What is Whipple's disease?
« on: 15/06/2007 22:49:38 »
Working in a laboratory, I see very few 'real patients'
and follow some cases through clinical reports from my
colleagues and friends.
Then I read med. literature and case reports, of course.
In the last few years Whipple's Disease (WD) has drawn
my attention for various reasons:

- Intriguing clinical presentations.
- technical difficulties in making diagnosis.
- cheap, easy and instantly accessible cure (when caught on time).
- defined as a 'very rare' disease, but underdiagnosed frequently.
- many cases reported from Europe (many in U.K., Germany and Switzerland?).
- first observed one century ago (1907), it is still a sort of 'mystery'.


"Earlier diagnosis leads to earlier treatment and hopefully the prevention of chronic disabling complications and needless mortality from this once uniformly fatal condition."    James DG and Lipman MC, 2002 (see below)



I open the discussion with simple bits and pieces plus whipple-pictures
Hope many of the NKSforum readers will partecipate in this open thread.
 






I overstressed on purpose intriguing reports from medical literature to open the discussion on how to find a cheap and easy way to avoid these treatable ailments going undetected for months and years, with all the human suffering involved.


In a few words, modern PCR technology will eventually allow us -in the near future- to develop special inexpensive microchips to detect by one simple blood test most of the germs that we carry 'on board'.

An infectious disease will be diagnosed in seconds starting from the germ this time, not from patients' medical history, signs and symptoms.

Quite a little revolution in clinical medicine, but today we do already use other 'screening' tests.
Of course we'll need top notch sensitivity and the highest number of bugs searched through a single test, to make it reliable, easy and cheap.
Unfortunately, these days we see some of this magic hightech show used mostly in forensic medicine.

Yes Karen,

Whipple's disease is so variegated in terms of symptoms
that goes from nothing to any sign or symptom you can imagine!
This makes it useless to report their list.





A visible bacterium which is reluctant to common cultivation

By means of electron microscopy, the bacterium of Whipple´s disease is well characterized as rod-shaped, approximately 2,5 um in length, with a diameter of 0,25 um.

Its most peculiar ultrastructural feature is a trilaminar membrane with a broad electron dense outer layer. ( 1, 2 )
 
 Since the bacterial nature of Whipple´s disease was recognized in 1961, several attempts were performed to culture the associated bacterium. Some of them were initially assumed to have been successful, but their results could never be reproduced by others. ( 3, 4, 5, 6 )

In 2000, a first case of successful cultivation associated with human fibroblast cell lines was reported, which eventually could be reconfirmed. ( 7, 8; 6 ) In 2003, the new knowledge of the genome provided information  for a first in vitro cultivation without host cells ( 9 ). (see: Bacterium/Growth )

YAYYYYYYYYYY! thanks Iko it is actually very interesting. So symptoms can range from nothing to tons of stuff! That must make diagnosing very difficult indeed!

5.0 - Questions about Whipples in Medicine

5.1 - What is Whipple's Disease?
Whipple's disease is a multisystem disorder caused by chronic infection with a bacterium, Tropheryma whippelii. Many patients have malabsorption, which means an impairment of the body's ability to absorb certain nutrients. The disease frequently causes weight loss, irregular breakdown of carbohydrates and fats, resistance to insulin. Most patients have dysfunctions of the immune system. When recognized and treated, Whipple's disease can be cured. Untreated, the disease is usually fatal. Read more at the National Digestive Diseases Clearing House or at Whipple´s Disease Online.

Whipple's disease was named after George Hoyt Whipple, who first observed the disease in 1907 at Johns Hopkins University in Baltimore, Maryland. Whipple was a staff member there from 1905 until 1914. He won the 1934 Nobel Prize in physiology and medicine. (See Blaine Whipple's article on this site and George Hoyt Whipple's ancestry in the WhippleGenWeb.)

(This question was answered with the help of Dr. med. Axel von Herbay, Privatdozent für Pathologie, Pathologisches Institut, Universitätsklinikum, Im Neuenheimer Feld 220, 69120 Heidelberg, Germany. Dr. von Herbay can be reached by e-mail at Axel_von_Herbay@med.uni-heidelberg.de, on the Web at www.WhipplesDisease.net, by telephone at +49 6221 562675, or by fax at +49 6221 562675.)

I hope you now have got the 'basics' of Whipple Disease,
I will add many more links later, don't worry.
Everybody is invited to post whipple bits here.
The final story has to be written still.

Then we'll collect a series of abnormal presentations
of the very same disease...looking like something else!



Whipple's disease: a granulomatous masquerader.

James DG, Lipman MC.
Department of Medicine, Royal Free School of Medicine, Rowland Hill Street, London NW3 2PF, UK.

Whipple's disease is a multisystemic infection that affects middle-aged white men. It typically presents with fever, polyarthritis, diarrhea, steatorrhea, and weight loss.
Many other systems can be involved, however, including the central nervous system, heart, lymphatics, lungs, bone marrow, and skin. Recent work has demonstrated the causative organism to be a complex bacteria, Tropheryma whipplei. The diagnosis is established most securely by periodic acid-Schiff staining of foamy monocyte-macrophages in biopsy tissue and body fluids, by electron microscopy, which reveals bacilli within membrane-bound vesicles, and by molecular amplification techniques using polymerase chain reaction of tissues and body fluids. The differential diagnosis includes chronic multisystemic infections and granulomatous disorders, because Whipple's disease is a fascinating blend of both. The condition can resemble sarcoidosis and mycobacterial disease and fungal, protozoal, and bacillary infections. Earlier diagnosis leads to earlier treatment and hopefully the prevention of chronic disabling complications and needless mortality from this once uniformly fatal condition.

Clin Chest Med. 2002 Jun;23(2):513-9, xi-xii.

Here is one of the most intriguing episodes of Whipple hunting:
the ultra-advanced treatment for a common disorder (Rheumatoid
Arthritis, or Still's disease) makes the real rare disease come OUT!
...and it's a report from Germany.

Exacerbation of Whipple's disease associated with infliximab treatment.

Kneitz C, Suerbaum S, Beer M, Müller J, Jahns R, Tony HP.
Department of Clinical Immunology and Rheumatology, Medizinische Poliklinik, University of Würzburg, Germany. kneitz_C@klinik.uni-wuerzburg.de

A 34-year-old man with chronic inflammatory joint disease and recurrent fever over 6 years was diagnosed as having Still's disease. Treatment with corticosteroids and azathioprine was ineffective. Therefore, infliximab/ methotrexate was started. The patient subsequently developed a wasting disease with rapid weight loss, erythema nodosum, diarrhoea, progressive lymph node enlargement, and a sigmoido-vesical fistula. Histological analysis of several enlarged lymph nodes, the margins of the fistula, and the small bowel established the diagnosis of Whipple's disease (WD). The presence of Tropheryma whipplei (Tw) DNA in the tissues was confirmed by polymerase chain reaction (PCR). Careful re-evaluation of biopsies taken from the ileum and the liver 2 years earlier, which at that time was not judged to be diagnostic for WD, retrospectively showed subtle histological signs of WD and were positive for Tw DNA.
In summary, infliximab treatment seems to increase the risk of exacerbation of WD.
WD should be carefully ruled out prior to application of tumour necrosis factor-alpha (TNF-alpha) blockade.

Sorry, I just found a major whipple-website,
"the" thing to start safely from here:
it had been temporarily lost in my notes.
Ready to click and read.
Enjoy





The treatment:  Sulfamethoxazole; Trimethoprim, SMX-TMP Tablet (Tab 400;80 mg;mg) for 1-2 years.

Before disappearing for a while and going again
through my messy notes about Whipple's disease,
I post another mysterious case for the affectionate
readers of 'fastidious' persistent infections:
here Whipple was dressed up as dermatomyositis,
an 'autoimmune' disorder of uncertain etiology...
...a pediatric case, quite rare indeed.

Actually it's easy: WD&DM give only this 1 citation on PubMed!  [:D]

Dermatomyositis and Whipple's disease.

Helliwell TR, Appleton RE, Mapstone NC, Davidson J, Walsh KP.
Department of Pathology, University of Liverpool, UK.

A 14-year-old boy presented with a 3-year history of a skin rash typical of juvenile dermatomyositis, and a 2-month history of mild proximal weakness, myalgia, and weight loss. A quadriceps biopsy showed perifascicular fibre atrophy, focal necrosis and regeneration, immunohistochemical labelling for HLA-1 on the surface of the fibres, and focal C5-9 deposition in capillaries. Macrophages with diastase-resistant, PAS-positive cytoplasm were present. Ultrastructural studies showed electron dense and membranous debris. The patient's symptoms responded to intravenous immunoglobulin and oral prednisolone.
Four months after discontinuing prednisolone, the patient developed cardiac failure, ventricular tachycardia, and a recurrence of his rash. The 16S ribosomal RNA specific for Tropheryma whippelii was identified by polymerase chain reaction (PCR) analysis in skeletal and cardiac muscle. The myalgia and skin rash responded to prednisolone and oral co-trimoxazole, and the tachycardia is controlled by oral verapamil. This patient appears to have a novel association of juvenile dermatomyositis and Whipple's disease.

Neuromuscul Disord. 2000 Jan;10(1):46-51.




Even Toxoplasma gondii has been involved in
several cases of autoimmune dermatomyositis.

Early diagnosis of Whipple's disease is crucial to
lower the number of useless autoptic diagnoses.
This is one "just on time" case in point:

New patient-friendly technologies for Whipple's disease hunting:
fiberoptic endoscopy cannot inspect the entire small intestine,
but only the first part of it, called duodenum, and a bit further...

In some 'occult' cases, whipple bacteria may hide in unreachable
sites of the small intestine.  Now they have to deal with micro-
electronics progress!


Refractory Whipple's disease with anaemia: first lessons from capsule endoscopy.

Fritscher-Ravens A, Swain CP, von Herbay A.Endoscopy Unit, St Mary's Hospital, London, UK.

Whipple's disease is a chronic multisystem disorder caused by infection with the rod-shaped bacterium, Tropheryma whippelii. We report the case of a 65-year-old woman with intestinal Whipple's disease that had been refractory to monotherapy with a number of antibiotics over a 2-year period. The patient then presented with watery diarrhoea, cachexia (body mass index 18 kg/m (2)) and chronic anaemia (haemoglobin 7.6 g/dl). Wireless capsule endoscopy showed that the disease affected the entire small intestine. Focal occult areas of bleeding were observed in different parts of the jejunum. The capsule's transit time through the small intestine was 2 hours 43 minutes. Capsule endoscopy allows novel insights into the pathophysiology of Whipple's disease.

Everything and its opposite, these are the 'typical' extremely vague symptoms
of Whipple disease according to clinical reports in medical literature.
As insomnia is rarely found, even hypersomnia has been recently reported:

Hypersomnia in Whipple disease: case report.

Maia LF, Marta M, Lopes V, Rocha N, Lopes C, Martins-da-Silva A, Monteiro L.
Department of Neurological Disordes and Senses, Hospital Geral de Santo António, Largo Prof. Abel Salazar, 4099-001 Porto, Portugal.

Whipple disease (WD) is a rare systemic infection caused by Tropheryma whippelii. Neurological involvement has been recognised in 40% of patients, either as initial manifestations or during the course of the disease. We report on a 45 years-old man with WD with initial, persistent and irresistible episodes of daytime somnolence. The patient was HLA-DQB1*0602 positive (genetic marker for narcolepsy). WD diagnosis was suspected on clinical and MRI basis and confirmed by histological and immunohistochemical study of duodenal biopsy. Forty months later all clinical features improved, narcoleptic-like episodes disappeared and cerebral MRI and CSF normalised. Longitudinal neurophysiological studies revealed persistent sleep pattern abnormalities with sleep fragmentation, paucity of slow wave and of REM sleep. The disruption of the hypocretin circuitry in the hypothalamic - diencephalic region triggered by the infection was the probable cause of the hypersomnia and narcopleptic symptoms. WD should be added to the list of causes of secondary hypersomnia.

Could you explain Hypersomnia better please?

Sorry Karen,

I was sleeping!  [;D]

Hypersomnia should be 'super'sleep, too much sleep and somnolence during daytime.
This patient had a genetic predisposition to narcolepsy too...
Well, narcolepsy is...(wiki-wiki-wiki! [;)])

Narcolepsy

Narcolepsy is a neurological condition most characterized by Excessive Daytime Sleepiness (EDS). A narcoleptic will most likely experience disturbed nocturnal sleep, confused with insomnia, and disorder of REM or rapid eye movement sleep. It is a type of dyssomnia.

The main characteristic of narcolepsy is overwhelming excessive daytime sleepiness (EDS), even after adequate night time sleep. A person with narcolepsy is likely to become drowsy or to fall asleep, often at inappropriate times and places. Daytime naps may occur with or without warning and may be physically irresistible. These naps can occur several times a day. They are typically refreshing, but only for a few hours. Drowsiness may persist for prolonged periods of time. In addition, night-time sleep may be fragmented with frequent awakenings.

Four other classic symptoms of narcolepsy, which may not occur in all patients, are cataplexy, sleep paralysis, hypnogogic hallucinations, and automatic behavior. Cataplexy is an episodic condition featuring loss of muscle function, ranging from slight weakness (such as limpness at the neck or knees, sagging facial muscles, or inability to speak clearly) to complete body collapse. Episodes may be triggered by sudden emotional reactions such as laughter, anger, surprise, or fear, and may last from a few seconds to several minutes. The person remains conscious throughout the episode. Sleep paralysis is the temporary inability to talk or move when waking up. It may last a few seconds to minutes. This is often frightening but is not dangerous. Hypnagogic hallucinations are vivid, often frightening, dream-like experiences that occur while dozing, falling asleep and/or while awakening. Automatic behavior means that a person continues to function (talking, putting things away, etc.) during sleep episodes, but awakens with no memory of performing such activities. It is estimated that up to 40 percent of people with narcolepsy experience automatic behavior during sleep episodes. Daytime sleepiness, sleep paralysis, and hypnagogic hallucinations also occur in people who do not have narcolepsy, more frequently in people who are suffering from extreme lack of sleep. Cataplexy is generally considered to be unique to narcolepsy.

MyGoodness, me hope never get this narcoPEPSI!    [:o]

An unusual case of insomnia associated with Whipple encephalopathy: first case reported from Greece.

Papadopoulou M, Rentzos M, Vagiakis E, Zouvelou V, Potagas C, Bonakis A, Chatzipanagiotou S, Ioannidis A, Nicolaou C, Vassilopoulos D.Department of Neurology, University of Athens Medical School, Eginition Hospital, 74 Vas. Sophias Av., 11528, Athens, Greece. marpapgr@yahoo.co.uk

Whipple disease is a relapsing systemic illness caused by Tropheryma whippelii.
Central nervous system involvement occurs in 5%-40% of all patients. Hypothalamic manifestations occur in 31% of Whipple encephalopathy, including polydipsia, hyperphagia, change in libido and insomnia. We report a case of a 48-year-old man with severe insomnia, depression, dementia, dysarthria, myoclonic movements of the limbs and ophthalmoplegia. The diagnosis of Whipple encephalopathy was confirmed by PCR analysis of blood and faeces. He received a full dose of antibiotic treatment. Despite clinical improvement, resolution of the lesions detected in MRI scan of the brain and negative results of the PCR in blood, faeces and cerebrospinal fluid six months later, insomnia persisted and finally subsided after the administration of carbamazepine (600 mg/day). Our case supports the finding that carbamazepine might be useful in the treatment of insomnia associated with Whipple encephalopathy.

This time Whipple was dressed up as sarcoidosis,
a mysterious infectious-like granulomatous disorder
of uncertain etiology...but Tropheryma whippelii
had been hiding there for years.



Weight loss, joint pain and abdominal lymphadenopathy
as signs of sarcoidosis, but also of Whipple's disease 
[Article in Dutch]

Deeren D, Vanderschueren S, Ectors N, Blockmans D, Bobbaers H.
Afd. Interne Geneeskunde, Universitaire Ziekenhuizen Leuven, België. driesdeeren@hotmail.com

Two patients, a woman aged 66 and a man aged 56 years, with an inflammatory syndrome, weight loss, joint pain and abdominal lymphadenopathy received long-term treatment with corticosteroids for alleged sarcoidosis. No long-term remission was induced and the patients were referred for a second opinion. Eventually the diagnosis of Whipple's disease was established 5 years after the appearance of the first symptoms in the case of the female patient and 4 years after in the case of the male patient. Both patients showed a marked clinical improvement after treatment with trimethoprim-sulfamethoxazole.
An atypical presentation of alleged sarcoidosis should suggest the possibility of Whipple's disease, especially in the case of gastrointestinal symptoms and the failure to respond to corticosteroids, and warrants duodenal biopsy. The presence of granulomas with an elevated angiotensin-converting enzyme level is not pathognomonic for sarcoidosis. It is vitally important to distinguish the two disorders, as Whipple's disease is an infectious disorder that requires antibiotic therapy to prevent a fatal outcome.

Ned Tijdschr Geneeskd. 2003 Mar 29;147(13):620-4.





In this unfortunate case -several years ago- it was simply too late...

Chronic interstitial nephritis in Whipple's disease.

Schlumpf A, Marbet UA, Stöcklin E, Wegmann W, Lämmle B, Mujagic M, Jösch W, Thiel G, Thölen H, Olivieri W, Gudat F, Torhorst J, Zollinger HU, Mihatsch MJ.
Report is given on a 68-year-old man who suffered primarily from progressive weight loss and repeated episodes of fever and arthralgia.
Later, liver dysfunction and renal insufficiency developed. Liver and kidney biopsies disclosed granulomatous hepatitis and nephritis. Because of the morphologic and clinical findings, the diagnosis of Boeck's disease (sarcoidosis) was made. Shortly before death, diarrhea developed.
Autopsy revealed a massive systemic involvement in Whipple's disease proven by light and electron microscopy and immunofluorescence. Tuberculoid and epitheloid cell granulomas and isolated giant cells were found in addition to the biopsy findings in skeleton muscles, the small intestine, lymphnodes and bronchi. At autopsy, the kidney showed chronic interstitial nephritis. The literature of kidney involvement in Whipple's disease is reviewed. This is the first case with granulomatous interstitial nephritis and chronic renal insufficiency in an inadequately treated Whipple's disease.

Klin Wochenschr. 1983 Jan 3;61(1):25-33.

Whipple was masked as meningoencephalitis in a young woman here.
Infectious etiology was suspected and PENICILLIN administered...
without finding any germ!  But of course it worked -empirically- for
a few months.
Then Whipple came back as a severe cardiovascular problem, and
again managed to hide until a brain biopsy was performed.
A simple PCR test would have made it earlier and more safely.



Cerebral Whipple's disease with a stroke-like presentation and cerebrovascular pathology.

Peters G, du Plessis DG, Humphrey PR.
Department of Neurology, Walton Centre for Neurology and Neurosurgery, Liverpool, UK.

Although neurological symptoms are common in Whipple's disease, patients rarely have a purely neurological presentation and involvement restricted to the central nervous system is uncommon. A 39 year old woman presented with a meningoencephalitic illness, which responded to penicillin.
Eleven months later she developed recurrent stroke-like episodes. Patchy enhancing meningeal, cortical, and subcortical lesions thought to be vascular in origin developed within nine days of the onset of symptoms. No evidence was found of a cardiovascular source of emboli, vasculitis, or thrombophilic condition. A brain biopsy showed meningoencephalitic features suspicious of Whipple's disease associated with leptomeningeal arterial fibrosis and thrombosis.
DNA polymerase chain reaction confirmed Tropheryma whippelii in both blood and brain tissue.
The neurological manifestations of cerebral Whipple's disease are varied and very rarely include stroke-like symptoms. The pathogenesis of cerebral infarction in Whipple's disease is not well established but arterial fibrosis and endocarditis complicated by embolisation have been reported. This case emphasises the importance of early brain biopsy in unusual cases of stroke and illustrates the clinical utility of polymerase chain reaction to confirm Whipple's disease.

Whipple disease is a very rare infection
mainly observed in middle-aged men and
only in some cases affecting the brain.
Statistically, of course.
But here there was a young boy and ONLY
the central nervous system was touched:



Presumed central nervous system Whipple's disease in a child: case report.

Tan TQ, Vogel H, Tharp BR, Carrol CL, Kaplan SL.
Department of Pediatrics, Baylor College of Medicine, Houston, Texas, USA.

Whipple's disease is a rare, chronic, multisystem illness that is pathologically characterized by the accumulation of macrophages in the involved tissue that have a positive periodic acid-Schiff reaction. It is typically seen in middle-aged white men, and only four cases involving persons younger than 15 years of age have been reported. CNS Whipple's disease without intestinal manifestations is rare; only six cases have been reported in the literature, all involving adults. We report the case of a young boy with clinical, laboratory, radiographic, and pathological signs and symptoms consistent with CNS Whipple's disease who responded to therapy with trimethoprimsulfamethoxazole.

Clin Infect Dis. 1995 Apr;20(4):883-9.

Any comment, criticism, contribution?
While I'm here waiting, I post a new Carnival

I love the pictures.. and Iko is this primarily a  disease that strikes men, or do a number of women get it to, albeit rarely...

Whipple disease is a very rare infection
mainly observed in middle-aged men and
only in some cases affecting the brain.
Statistically, of course.

Mostly middle-aged men, and until few years ago proper diagnostic tools were lacking.
Consequently abnormal presentations, like brain involvement without gastrointestinal symptoms (diarrhea), arthralgia, fever and wasting were probably overlooked.
Since the development of Polymerase Chain Reaction (PCR) genetic techniques, major progress has been achieved in this field: incredibly abnormal presentations are being discovered and reported more and more frequently, and normal people hosting the germ identified (healthy carriers are not uncommon).
As in many other medical issues, the final story has still to be written.
My genuine interest as a 'reader', as you probably understood, is about whipple disease overlapping with mysterious 'autoimmune' disorders.  Finally an infectious cause for a group of ailments that are frequently supposed to be simply based on an immune disorder, our defence system attacking its own territory. And treated by immune suppression, that shouldn't be the case when a 'fastidious' pathogen is fussying around.

Hey,

I'm not going to report and copy ALL whipple cases from MedLine!
But if you check the previous abstracts, you'll find women too...
In autoimmune disorders women win 10 to one, approximately.
Immune systems -is suggested- are heavily controlled by sex hormones.
We should ask Chris about Whipple naughty beasts...
he doesn't seem interested, or he's just too busy right now.
May be he had a very bad Carnival in Venice!  [;D]

When Tropheryma whippelii hits the central nervous system only,
this great masquerader becomes almost an 'invisible' pathogen:

Reversal of dementia associated with Whipple's disease
by trimethoprim-sulfamethoxazole, drugs that penetrate the blood-brain barrier.

Ryser RJ, Locksley RM, Eng SC, Dobbins WO, Schoenknecht FD, Rubin CE.

A previously healthy 67-yr-old man presented with progressive dementia over an 11-mo period. Evaluation revealed evidence of malabsorption. Jejunal biopsy established the diagnosis of Whipple's disease. No other etiology for the patient's dementia was uncovered. Treatment with trimethoprim-sulfamethoxazole resulted in rapid elimination of Whipple's bacilli from the jejunum and complete reversal of the patient's dementia over a 6-mo period. Significant levels of trimethoprim and sulfamethoxazole were easily quantitated in the cerebrospinal fluid during therapy. There is increasing recognition of progressive neurologic disease in patients with Whipple's disease who were treated with tetracycline. The reversal of presumed central nervous system disease in this case suggests that drugs that penetrate the blood-brain barrier might be preferable for the initial treatment of Whipple's disease.

Cerebral Whipple's disease as a cause of reversible dementia.

Unità Operativa di Neurologia, Ospedale Geriatrico Sestilli, I.N.R.C.A., Ancona, Italy. t.rossi@inrca.it

We describe a case of reversible dementia caused by Tropheryma whippelii (TW). Diagnosis was confirmed by a positive polymerase chain reaction for this pathogen both on serum and cerebrospinal fluid. Specific antibiotic therapy resulted in distinct clinical and neuroradiological improvement. Control polymerase chain reaction for T. whippelii on serum and cerebrospinal fluid was negative.

A prospective study of reversible dementias:
frequency, causes, clinical profile and results of treatment.

Srikanth S, Nagaraja AV.
Dementia Programme, Department of Neurology, Singapore General Hospital. drssrikanth@rediffmail.com

BACKGROUND: Dementia due to potentially reversible etiologies is an important group of dementias to be identified not only because of the number of such Patients encountered but also due to the potential for substantial improvement with treatment.
AIMS: To prospectively investigate the frequency and causes of dementias with potentially reversible etiologies; to examine the clinical features of this subgroup with a view to identifying a signature profile and to determine if this potential reversibility translates into actual reversibility with appropriate treatment. SETTING AND DESIGN: A prospective longitudinal study of patients with dementia presenting to the outpatient services of a tertiary referral hospital. Methods: All Patients above 40 years referred for evaluation of cognitive complaints were serially enrolled and underwent clinical examination, various laboratory tests and neuroimaging. Patients were followed-up for one year.
STATISTICAL ANALYSIS: One way analysis of variance for continuous variables followed by post hoc comparisons using Scheffe's procedure.
RESULTS: A total of 129 patients met Diagnostic and Statistical Manual of Mental Disorders edition 4 (DSM IV) criteria for dementia and qualified for inclusion into the study. Twenty-four patients (18%), all with moderately severe cognitive [mean mini mental state examination (MMSE) score +/- SD = 17.9 +/- 4.8] and neuropsychiatric [mean neuropsychiatric inventory (NPI) score +/- SD = 30.7 +/- 8.7] dysfunction were diagnosed to have reversible causes - neuroinfections in 11 patients, normal pressure hydrocephalus in 8 patients and vitamin B12 deficiency in 5 patients. The majority of these patients had gait and urinary dysfunction reminiscent of subcortical dementias. These reversible causes were clinically suspected in only 58% of patients. In 20/24 patients in whom follow up was possible mean MMSE score had improved to 22.2 and mean NPI score had improved to 8.0, following 6 months of treatment.

CONCLUSIONS: Reversible causes, especially neuroinfections and vitamin B12 deficiency accounted for 18% all dementias in this study.
The majority of these conditions was not clinically suspected though resulting in moderate to severe cognitive and psychiatric dysfunction. Most of these patients had a subcortical pattern of dementia and showed substantial improvement with treatment.

It looked like a lymphoma, but under the microscope
an infection was diagnosed: Whipple's disease!


Abdominal lymphomas, convulsive seizure and coma: a case of
successfully treated, advanced Whipple's disease with cerebral involvement.

Mohm J, Naumann R, Schuler U, Ehninger G.
Medizinische Klinik und Poliklinik I, Universitätsklinikum Carl Gustav Carus der Technischen Universität Dresden, Germany.

Whipple's disease is a rare, generalized inflammatory disorder due to the recently described bacterium Tropheryma whippelii. We report an unusual, successfully treated case of a 32-year-old woman, who presented with a 25 month history of large abdominal lymphomas, polyserositis and cachexia. The diagnosis of Whipple's disease was confirmed by duodenoscopy, lymph node and duodenal histology and polymerase chain reaction analysis of biopsy material and cerebrospinal fluid. A prolonged convulsive seizure with a subsequent 5 day period of coma were interpreted as signs of cerebral involvement. Under antibiotic treatment with trimethoprim-sulfamethoxazole (co-trimoxazole) the patient recovered completely, CT scans showed a complete regression of abdominal lymphomas. The therapy was continued over 18 months without the occurrence of a relapse.

One of many Whipple-websites is from Ohio Health:
everything is well explained and easy to find...


...even diagnostic difficulties are smartly described:

Screening and diagnosis

Whipple's disease is rare and many doctors may be unfamiliar with the disorder, so it's often diagnosed in its late stages. However, the earlier the diagnosis, the better because of the serious health risks associated with nontreatment

Hi Karen!

I took an extra boost of vitamin hyper megadoses and finally got your point!
Yes, Whipple bacteria can affect the heart and its valves, giving subacute endocarditis, strokes and things...but very rarely -because it is a very rare disease- and in the same fashion as many other much more common germs.
Some studies suggest that Whipple bacteria cause less inflammation than the other germs in most of the cases, but this is not clear (like all the rest).

Whipple's endocarditis: review of the literature
and comparisons with Q fever, Bartonella infection, and blood culture-positive endocarditis.

Fenollar F, Lepidi H, Raoult D.
Unité des Rickettsies, Centre Nationale de Recherche Scientifique, Unité Mixte de Recherche 6020, Marseille, France.

Whipple's disease is a systemic infection sometimes associated with cardiac manifestations. Recently, there has been an increase in the number of reported cases of Whipple's endocarditis. The purpose of our study was to describe this entity. Data from 35 well-described cases of Whipple's endocarditis were collected and compared with those of blood culture-positive endocarditis, Q fever endocarditis, and Bartonella endocarditis. Some patients with generalized Whipple's disease presented with cardiac involvement, among other symptoms. Others presented with a nonspecific, blood culture-negative endocarditis with no associated symptoms. In comparison with cases of endocarditis due to other causes, congestive heart failure, fever, and previous valvular disease were less frequently observed in the cases of Whipple's endocarditis. Without examination of the excised valves, the diagnosis of infective endocarditis could not have been confirmed in most cases. Treatment is not well established. Whipple's endocarditis is a specific entity involving minor inflammatory reactions and negative blood cultures, and its incidence is probably underestimated.

Clin Infect Dis. 2001 Oct 15;33(8):1309-16.









Whipple's disease: a difficult diagnosis?

Peters FP, Elbrecht EA, Wouters RS, Engels LG, Stockbrügger RW.
Department of Gastroenterology, University Hospital Maastricht, Netherlands.

We present 3 patients with Whipple's disease all characterized by a longstanding prodromal period with progressive weight loss, diarrhoea, lymphadenitis and arthralgia or arthritis. Sarcoid-like Whipple's disease was diagnosed in one patient. He was treated with antibiotics. Initially his condition improved; however, a cerebral relapse developed which was treated successfully by ceftriaxone and cefixime. Extraintestinal Whipple's disease (lymph node localisation) was diagnosed in another patient treated successfully with antibiotics. A third case of Whipple's disease was unexpectedly diagnosed by laparotomy and partial small bowel resection. He was not treated till 2 years later with tetracycline. After 1 year of treatment his condition had improved.

Wrong diagnosis for 16yrs,
then diarrhea started, so
Whipple was suspected and
...FOUND RIGHT THERE!!!
(17yrs ago)


Whipple's disease with axial and peripheral joint destruction.

Scheib JS, Quinet RJ.
Department of Internal Medicine, Ochsner Clinic, New Orleans, La.

A seropositive white man had follow-up for 16 years with a diagnosis of palindromic rheumatism. Treatment had included parenteral gold, methotrexate, prednisone, hydroxychloroquine sulfate, and penicillamine before diarrhea led to a biopsy-proven diagnosis of Whipple's disease.
Clinical and radiographic criteria for ankylosing spondylitis were met. In addition to classic Whipple's arthropathy, he had the combined but singular findings of pancarpal destruction and cervical apophyseal fusion. HLA typing revealed the B7 antigen. This case illustrates the pitfalls in diagnosis of a chronic polyarthritis that has, as a typical feature, a long latency before manifesting its more specific signs and symptoms (ie, diarrhea, malabsorption, and hyperpigmentation). Care should be taken during evaluation of any disease with atypical and nonspecific features (eg, positive rheumatoid factor in a patient with polyarthritis) and one should continue to reevaluate the original impression while confirmatory evidence is lacking. Moreover, the roentgenographic findings of pancarpal narrowing, apophyseal fusion, and advanced iliofemoral joint disease, in addition to sacroiliitis and syndesmophyte formation, challenge the generally held notion that Whipple's arthropathy is a nondestructive joint disease.

iko,

First, let me say thank you to you for your insight and thoughts on Tropheryma whipplei bacteria.

A good friend of mine has recently begun treatment consistent with that for Whipple's disease.

After reading a bit on this bacteria and the Whipple's disease, I have come to believe that it is considered to be rare only because it is so difficult to observe.

Also, I am curious about a few potential issues relating to this bacteria:

- Is this bacteria is able to be passed from one person to another by becoming airborne?

- Has any researcher actually ever seen this bacteria alive, since an electron microscope does not allow for live viewing?

- If not, how does this restrict the effort of researchers to understand the nature of this bacteria?

-  Could many, many diseases that are presently known to the medical community be simply manifestations of different stages of this bacteria's existence within its human host and be incorrectly viewed as stand alone diseases?

- Are some or all of the bacteria in the family of this bacteria being underestimated in terms of their ability to work together?

- Can evolutionary change to any of the (six?) bacteria in this family  allow a systematic evolution from one to another to another ... and ultimately to the T whipelii?

- Is it possible that this bacteria plays a very substantial role in cancer diseases?

- Do you think that routine efforts to check for this bacteria and further understand the likelihood of its role in medical conditions listed on the following website as soon as a few of these symptoms are recognized (http://www.mayoclinic.com/health/whipples-disease/DS00757/DSECTION=2) would help to substantially increase advanced detection of this bacteria, prevent more advanced illnesses and deaths, and thus save the medical industry money?

-  Do you believe that until this bacteria is dressed up in threads of economics and globally paraded before the medical insurance industry as a profit thief that that industry will continue to underestimate it or overlook it?

Thank you again for your insight and for your devotion to this subject.

I look forward to seeing what your responses to these questions are.

Dear understudy,

thank you so much for joining us
in this whipply discussion.
I'll reply your multiple questions asap!
For now I suggest not to focus on one single germ
causing many diseases, but on MANY different 'fastidious'
germs causing troubles in few predisposed individuals: this is the
mainframe of this whipple experiment here.
I'm not an expert: sometimes it helps!  [;D]
Cheers,

OK understudy,

I'll reply your multiple questions as
a no-expert, just your discussant and
a simple 'reader' of intriguing cases
regarding obnoxious fastidious germs.

iko,
First, let me say thank you to you for your insight and thoughts on Tropheryma whipplei bacteria.
A good friend of mine has recently begun treatment consistent with that for Whipple's disease.

After reading a bit on this bacteria and the Whipple's disease, I have come to believe that it is considered to be rare only because it is so difficult to observe.

I think Tropheryma whipplei may be a common germ in our environment, nevertheless it causes troubles in very few people. Even considering a consistent number of undiagnosed cases, it should be a rare pathogen anyway.
I overstressed on purpose intriguing reports from medical literature to open the discussion on how to find a cheap and easy way to avoid these treatable ailments go undetected for months and years, with all the human suffering involved.



Also, I am curious about a few potential issues relating to this bacteria:
- Is this bacteria is able to be passed from one person to another by becoming airborne?

I think it survives happily in the environment (Actinomycetae) with its triple layer membrane, consequently air, dust, water and contacts may be the routes of infection.
As in many other cases, infection is routinely kept under control efficiently by the defence systems: only in rare instances -probably because of some immune defect- whipple bacteria manage to spread around.
See the previously cited reviews for details.


- Has any researcher actually ever seen this bacteria alive, since an electron microscope does not allow for live viewing?

Interesting point: Whipple bacteria had been successfully cultured at the end of the last century.  They are intracellular germs...I think it's quite difficult to see them alive.

- If not, how does this restrict the effort of researchers to understand the nature of this bacteria?

-  Could many, many diseases that are presently known to the medical community be simply manifestations of different stages of this bacteria's existence within its human host and be incorrectly viewed as stand alone diseases?

Good point, and the actual target of this thread, but never forget that this could be just one of several germs playing dirty tricks and hiding behind some 'idiopathic' human diseases.
I decided to start with this peculiar one knowing that it's not alone.


- Are some or all of the bacteria in the family of this bacteria being underestimated in terms of their ability to work together?

- Can evolutionary change to any of the (six?) bacteria in this family  allow a systematic evolution from one to another to another ... and ultimately to the T whipelii?

I'd like to be able to answer these questions!   [:-X]

- Is it possible that this bacteria plays a very substantial role in cancer diseases?

We cannot exclude it, if we accept the connection between persistent infection, chronic inflammation and cancerogenesis. Helicobacter pylori causes intestinal lymphomas and gastric cancer.

- Do you think that routine efforts to check for this bacteria and further understand the likelihood of its role in medical conditions listed on the following website as soon as a few of these symptoms are recognized (http://www.mayoclinic.com/health/whipples-disease/DS00757/DSECTION=2) would help to substantially increase advanced detection of this bacteria, prevent more advanced illnesses and deaths, and thus save the medical industry money?

Give me some time to check this out...

-  Do you believe that until this bacteria is dressed up in threads of economics and globally paraded before the medical insurance industry as a profit thief that that industry will continue to underestimate it or overlook it?

Sometimes peculiar issues and rare disorders are ignored just like that: I would not always search for a hidden negative influence by medical insurance industry or others.
I tend to think that we need many more new smart brains most of all, honest enthusiastic researchers.  I've met many, maybe we need more.
Medical research about fastidious persistent germs could be partly supported by our govs and independent foundations.  Major pharmaceutical companies will follow


Thank you again for your insight and for your devotion to this subject.

I look forward to seeing what your responses to these questions are.

Thank you so much for your difficult questions:
I apologize right away for my short replies...
I prefer synthetic and condensed communication.
Regards,

ikod

I overstressed on purpose intriguing reports from medical literature to open the discussion on how to find a cheap and easy way to avoid these treatable ailments going undetected for months and years, with all the human suffering involved.


In a few words, modern PCR technology will eventually allow us -in the near future- to develop special inexpensive microchips to detect by one simple blood test most of the germs that we carry 'on board'.

An infectious disease will be diagnosed in seconds starting from the germ this time, not from patients' medical history, signs and symptoms.

Quite a little revolution in clinical medicine, but today we do already use other 'screening' tests.
Of course we'll need top notch sensitivity and the highest number of bugs searched through a single test, to make it reliable, easy and cheap.
Unfortunately, these days we see some of this magic hightech show used mostly in forensic medicine.

iko,

Thank you very much for your responses to my questions.

Kindly take notice of some relatively new findings regarding previous studies on the prevalence of Tropheryma whipplei in certain populations.

http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1890548

If this new study is accurate, then how does this affect the widely held belief that for those testing positive for the Tropheryma whipplei bacteria in their saliva that the bacteria itself is less responsible for disease than a defect in one's immune system or individual immunity to Tropheryma whipplei?   <<<<<<<this is the key question here!

Previous estimates have suggested that as many as 40% of the population carry Tropheryma whipplei in their saliva, and that only a small percentage of those testing positive for it have Whipple's disease - or one of the accepted forms of it.

Is it possible that the methods used in the new study could still have overlooked additional false positives, despite greatly reducing the prevalence of Trpheryma whipplei in the general population?

Am I misreading the data or are as much as 80% of the positives reviewed, in this May 2007 study, "false positives?"

Thank you again for your time and effort.

Thanks for your help overstudy!  [;D]

This contribution of yours shows us how fragile is our so called 'evidence' sometime.
Whipple bacteria are not anymore so common in humans as previously stated and we have to wait for properly arranged studies to know the percentage of 'healthy carriers' in our population.
We wanted to play the Helicobacter pylori game with Whipple too: common germ and few affected patients. No, this time is going to be different and maybe more complicated.
Of course, this is Whipple, the great granulomatous masquerader!

Still, impo*, we urgently need a cheap and reliable routine laboratory test for patients.

iko,

Welcome back.

To celebrate your return, I'll ask a new question.

Do parasites co-exist with "Tropheryma whipplei" in human hosts?

Just asking.

Thank you so much, again.

Hi understudy,

I took a couple of weeks off in fact.
Now I'm back to the Whipplipedia forum!
Thank you for your precious support around here.
Parasites, defined as protozoa (Toxoplasma, Giardia, Amoebas etc.) or multicellular (Nematoda, Cestoda) like pinworms, surely may coexist in any patient affected by any bacterial infection, so supposedly even in Whipple disease.
In certain countries, people don't carry just one, but 2 or 3 different species of parasites per person, due to the precarious hygienic standards.
I don't remember a single case report of whipple disease and any parasitic infestation of sort.
That doesn't certainly mean that there aren't any!
Why are you interested in such a peculiar association?
Do you suspect an immune deficiency in WD patients?

Bacterial infections swich on different immune reactions.
Common bacteria stimulate antibody production and macrophages' appetite.
Intracellular (e.g. TB, WD) bacteria need a macrophage and T-Lymph more complex response.
Parasites and fungi as well require a T-Lymph compartment fully operative.
As you probably read before, years ago a slightly defective T-cell subset has been suspected to contribute to Whipple disease...but these data need confirmation, like those PCR results!  [;D]

iko,

Sorry for my delay in responding.

Do most symptoms for a person suffering from parasites mimic those of a person suffering from a classic case of Whipple's disease?

Once antibiotic treatment for classic Whipple's disease is ongoing, should routine blood analysis show histaminase and basophils reacting as though one is being treated for parasites?

Are these just overlapping symptoms and reactions?

Thank you again.

There are many different species of parasites and they cause a wide variety of symptoms, so the 'classic' presentation of Whipple's disease, diarrhea-fever-weightloss-anemia and joint pain may overlap a parasite infestation.
Anyway, parasites are carefully searched in any severe case of diarrhea.


Once antibiotic treatment for classic Whipple's disease is ongoing, should routine blood analysis show histaminase and basophils reacting as though one is being treated for parasites?

I cannot answer this question.
WD bacteria duplication time is very long: approx. 18days.
When you start antibiotic therapy bacteria don't die in a short time, and for this reason treatment has to be extended (at least one year).


Are these just overlapping symptoms and reactions?

Thank you again.

If you consider the previously reported cases, you'll find that WD may be misdiagnosed as rheumatoid arthritis or dermatomyositis, as sarcoidosis or even non-Hodgkin lymphoma.
In rare cases WD has been discovered as  the unsuspected cause of reversible dementia.
Whipple's disease has never been reported misdiagnosed as a parasite infestation.
Parasitic diseases are diagnosed by specific tests: it's easy to rule them out.
One exception could be intracellular protozoa like Toxoplasma and Babesia, but this is another story...

This is the aim of this thread: difficult diagnosis and -maybe in rare cases- the 'real' cause of diseases of uncertain(!) etiology.

iko,

Let me thank you so much for your compelling response.

Intracellular parasitic infestation never misdiagnosed as a Whipple's disease?

It appears that "another story" is little understood and rapidly changing, even if intracellular parasites and Tropheryma Whipplei are mutually exclusive, which remains to be "seen."

Again, thank you for your fine work.
