Whipple disease.
Whipple disease is a rare disease caused by infection with the bacterium Tropheryma whippelii. Humans are the only known host for the infection. The signs of systemic infection include gastrointestinal problems, weight loss, and arthritis. Signs of central nervous system infection include cognitive changes, supranuclear gaze palsy, altered level of consciousness, and movement disorders. The diagnosis is based on clinical findings as well as microscopic examination of biopsy specimens and, more recently, polymerase chain reaction (PCR) analysis, which has high sensitivity and specificity. Although the organism historically has been difficult to culture, several recent attempts have been successful. Antibiotic treatment is recommended for 1 year while monitoring the clinical signs and cerebrospinal fluid PCR results.

[Neurological manifestations of Whipple disease].
Whipple disease is an uncommon chronic bacterial infection due to Tropheryma whipplei. Clinical manifestations are protean (joint pain, fever, weight loss, abdominal pain, lymphadenopathies), and the diagnosis is often delayed. Although previously considered a late manifestation of Whipple disease, neurological involvement is now frequently the initial clinical manifestation and represents the greatest risk for long-term disability. All patients should be treated and monitored as if they had central nervous system disease even if they are asymptomatic. Neurological manifestations include dementia (56 percent), abnormalities of eye movements (33p. cent), involuntary movements (28 percent), seizures, hypothalamic dysfunction, myelopathy, ataxia and psychiatric manifestations. Uveitis, retinitis, optic neuritis and papilloedema may be found. 80 percent of the reported cases of neuro-Whipple had associated systemic symptoms or signs but many patients are presenting without concurrent intestinal manifestation. Thus, the disease may remain undiagnosed or misdiagnosed, as rheumatoid arthritis or sarcoidosis. Traditionally, the diagnostic procedure of choice is biopsy of the duodenal mucosa by demonstrating PAS-positive foamy macrophages. However, not all cases have small bowel infiltration and tissue obtained from sites clinically affected may be helpful. CT and MR images of the central nervous system are normal or not specific: atrophic changes, mass lesions, focal abnormalities and hydrocephalus. The application of a PCR assay against Tropheryma whipplei has transformed the diagnosis. Positive results have been obtained from several tissues and from CSF and PCR is more sensitive than other techniques. All patients must be treated with antibiotics which cross the blood-brain barrier. Most agree that initial treatment with a combination of parenteral penicillin and streptomycin for at least 14 days is appropriate, thereafter cotrimoxazole orally 3 times a day for at least one and probably for two years. Third generation cephalosporins, rifampicin and chloramphenicol have been used successfully. PCR is recognized to be a useful tool for monitoring progress but it is sometimes difficult to reverse established neurological defects.

[Whipple disease--a rare systemic disease].
Whipple's disease is a rare, without antibiotic treatment deadly systemic infectious disease caused by the ubiquitary Gram positive bacterium Tropheryma whipplei. The agent can be demonstrated by light and electron microscopy and by PCR in tissues and body fluids affected. Men are affected more often than women. Most patients lose weight, have diarrhea, abdominal pain and arthralgias. In 10-40% of cases involvement of the CNS, often asymptomatic, is observed. PAS-positive macrophages in the lamina propria of duodenal biopsies are typical but not pathognomonic of Whipple's disease. Nowadays, the infectious agent should also be demonstrated by PCR. Treatment, mostly as a sequential therapy, is with antibiotics that cross the blood-brain barrier and should last for at least 1 year in order to avoid relapses. Before ending therapy the absence of Tropheryma whipplei in duodenal tissue and cerebrospinal fluid must be confirmed.

Inflammatory cell count and identification in specific duodenitis. (Celiac disease, Whipple's disease and Crohn's disease). Comparison with jejunal findings.
The authors studied the count and identification of inflammatory cells in duodenal biopsies of specific duodenitis. In celiac disease there is an increase of lymphocytes in the epithelial layer, and rich population of plasmacells in the lamina propria of duodenal mucosa. In Whipple's disease the reticulum cell component of lamina propria is increased, while total inflammatory cells are within normal limits, and both lymphocytes and plasmacells are decreased. The comparison between duodenal and jejunal findings shows similar data in celiac and Whipple's disease. In Crohn's disease the inflammatory cell count differs from controls only in presence of radiological or endoscopical features of duodenal involvement.

[Whipple disease: a single or multiple origin?].
After having been considered as an essentially digestive disease, Whipple's disease has appeared more and more to be a multivisceral disease with two main characteristics: on one hand Whipple's disease yields a diffuse infiltration of tissues by abnormal macrophages without any other inflammatory reaction; on the other hand, aspects of microbial invasion by intra or extracellular unique rod-shaped Gram+bacteria are found. This unusual pathological complex has alternatively been considered as suggestive of an immunological defect or as a very unusual type of bacterial infection. Though recent studies support the hypothesis of a primary microbial infection due to a hitherto undescribed bacterium (Tropheryma whippelii) or more or less related bacteria belonging to the actinomycetes family, they do not totally exclude a primary or acquired impairment of antigen processing by macrophages. Speculations about this fascinating pathophysiological model and about its optimal therapeutic modalities are not likely to reach a conclusion in the near future.

Cognitive and behavioral abnormalities in a case of central nervous system Whipple disease.
BACKGROUND: Whipple disease is a rare condition characterized by migratory polyarthralgias, fever, and chronic diarrhea. A subset of patients with the disease may either initially have or eventually develop symptoms of central nervous system involvement. DESIGN AND METHODS: The cognitive and behavioral functioning of a patient with central nervous system involvement from Whipple disease was studied during a 7-month period. Serial neuropsychological evaluations were used to quantify the nature of his cognitive and behavioral profile. SETTING: Neurology department of a university medical center. RESULTS: A variety of cognitive impairments were noted, most prominently in the domains of sustained attention, memory, executive function, and constructional praxis. There were striking behavioral manifestations as well, including disinhibition and confabulation. CONCLUSIONS: The case demonstrates a degree of higher-order central nervous system dysfunction rarely observed and quantified in connection with Whipple disease, and with important implications for differential diagnosis of certain neurologic conditions. We also call attention to some of the neuroanatomical correlates of this encephalopathic condition.

Whipple disease. Clinical review of 52 cases. The SNFMI Research Group on Whipple Disease. Société Nationale Française de Médecine Interne.
Whipple disease is a rare, multiorgan disease with prominent intestinal manifestations. We report a retrospective clinical study of 52 patients recruited in various parts of France from 1967 to 1994. Seventy-three percent of the patients were male. Clinical manifestations preceding the diagnosis were articular for 35 patients (67%), digestive for 8 patients (15%), general for 7 patients (14%), and neurologic for 2 patients (4%). At a later stage of the disease, 44 patients (85%) presented diarrhea, weight loss, and malabsorption, while 8 patients (15%) did not show any gastrointestinal symptom throughout the development of the disease. Forty-three patients (83%) presented arthralgia or arthritis, and 11 (21%) had prominent neurologic symptoms. In addition, cardiovascular symptoms were present in 9 patients (17%); mucocutaneous symptoms, in 9 patients (17%); pleuropulmonary symptoms, in 7 patients (13%); and ophthalmologic symptoms, in 5 patients (10%). All patients but 1 were given a positive diagnosis on histopathologic criteria: jejunal biopsy for 46 patients (90%), lymph node biopsy for 3 patients (6%), brain biopsy for 1 patient (2%), postmortem jejunal and cerebral biopsy for 1 patient (2%). With treatment, the disease evolved favorably in 47 patients (90%), while 5 patients (10%) had unfavorable outcomes (2 deaths from neurologic involvement, 1 patient with chronic dementia, and 2 patients with digestive symptoms insensitive to antimicrobial therapy). Of the 41 patients initially treated successfully and whose treatment has been completed, clinical evolution after discontinuation of treatment was favorable in 34 cases (83%). Clinical relapses occurred in 7 patients. No relapse was observed after treatment by trimethoprim-sulfamethoxazole, alone or following a combination of penicillin and streptomycin, or after the combination of penicillin and streptomycin, whatever the oral follow-up treatment prescribed. The evolution of patients showing a relapse was favorable in all cases after reintroduction of antibiotic therapy. These results are discussed in the light of previously published series and case reports of Whipple disease. The diagnosis of the disease remains difficult at an early phase or when digestive symptoms are absent. It is noteworthy that proximal enteroscopy is sometimes misleading, considered normal on macroscopic examination and nonspecific on pathologic grounds. A normal erythrocyte sedimentation rate represents another pitfall. Histopathology is the key for positive and differential diagnosis, and may require multiple and repeated biopsies. Findings from molecular biology confirm the central role of an uncultured Gram-positive bacillus which was named in 1992 Tropheryma whippelii. A recent report suggests that polymerase chain reaction (PCR) analysis of peripheral blood might allow the diagnosis of Whipple disease in some cases. However, immunologic or cellular parameters such as macrophagic function may play an important, although not clearly elucidated, role in the pathogeny of the disease. Trimethoprim-sulfamethoxazole should be considered the antimicrobial agent of choice in the treatment of Whipple disease, minimizing the risk of cerebral involvement and relapses.

Cerebellar ataxia and central nervous system whipple disease.
BACKGROUND: Whipple disease (WD) is an infectious disease, which may affect the central nervous system. Central nervous system symptoms are eventually present in as many as 43% of the cases. To our knowledge, cerebellar ataxia in WD has never been formally studied in any large series. OBJECTIVE: To determine the prevalence of cerebellar ataxia in central nervous system WD. RESULTS: Between January 1974 and December 2003, we identified 11 patients who met criteria for definite central nervous system WD, the second largest series to date. Surprisingly, while oculomasticatory myorrhythmia was recorded in only 1 patient (9%), cerebellar ataxia had been documented in 5 cases (45%). CONCLUSION: Our data suggest that cerebellar ataxia should be considered a more common feature of central nervous system WD.

Whipple disease and arthritis.
Whipple disease is a chronic, multisystem, curable, bacterial infection that usually affects middle-aged men and has a wide range of clinical manifestations. The most common symptoms are weight loss and diarrhea, preceded in three quarters of cases by arthritis for a mean of 6 years. In most patients, periodic acid-Schiff staining of proximal small bowel biopsy specimens reveals inclusions within the macrophages, corresponding to bacterial structures. However, patients with various manifestations of the disease may have no gastrointestinal symptoms and negative jejunum biopsy results. Before the onset of gastrointestinal symptoms, a strong index of clinical suspicion is the key to diagnosis. The classic setting is long-term, unexplained, seronegative oligoarthritis or polyarthritis with a palindromic or relapsing course, although chronic destructive polyarthritis and spondyloarthropathy have been repeatedly reported. Identification of the Whipple bacterium, Tropheryma whippelii, has led to the development of polymerase chain reaction as a diagnostic tool in patients in the early stages of the disease or with atypical Whipple disease. This technique can be used to detect the bacterium in many tissues and fluids, including synovial tissue and fluid. The recent cultivation of the Whipple bacillus should lead to the development of serologic tests, further facilitating diagnosis. These recent major advances may show that the infection is more frequent than previously suspected and may expand the clinical spectrum of the disease. It may also allow earlier diagnosis, thereby preventing the development of the severe systemic and sometimes fatal forms of the disease.

An unusual spinal presentation of Whipple disease.
SUMMARY: When Whipple disease (WD) is confined to the CNS, diagnosis may be difficult. We report a case of WD with spinal presentation in an otherwise healthy woman who had a 5-year history of relapsing-remitting cervico-thoracic myelopathy. We suggest that the diagnosis of WD should be considered in the presence of an enlarged and enhancing spinal cord even in the absence of any systemic involvement.

Hypersomnia in Whipple disease: case report.
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.

Diagnosis and monitoring of Whipple disease by polymerase chain reaction.
BACKGROUND: Whipple disease is a chronic, multisystem disorder associated with infection with Tropheryma whippelii, an organism that has not yet been grown on artificial media. In some cases, the diagnosis of Whipple disease is uncertain if it is based on histology alone. Although antibiotic regimens of various durations have been used, the disease recurs in about one third of cases. No test for cure is available. OBJECTIVE: To develop a test that is more sensitive and specific than histologic examination to diagnose Whipple disease and monitor the effects of antibiotic therapy. DESIGN: Retrospective, laboratory-based evaluations of stored tissue specimens. PATIENTS: 30 patients with clinically diagnosed, histologically confirmed Whipple disease and 8 patients in whom Whipple disease was clinically suspected but who did not have definitive histologic evidence. MEASUREMENTS: Pretreatment and post-treatment biopsy specimens of the small bowel and lymph node were tested by polymerase chain reaction for the presence of T. whippeli DNA. RESULTS: Results on PCR were positive in 29 of the 30 specimens from patients with histologically confirmed disease (sensitivity, 96.6%; specificity, 100%) and in 7 of the 8 specimens from patients in whom disease was clinically suspected. Small-bowel biopsy specimens were obtained after treatment from 17 patients (median duration of follow-up, 119 months); specimens from 12 of these patients had positive results on PCR. When these cases were correlated with therapeutic outcome, it was found that 7 of the 12 patients had clinical relapse during subsequent follow-up or had never responded to treatment (positive predictive value, 58% [95% CI, 28% to 85%]). In contrast, none of the 5 patients whose post-treatment biopsy specimens had negative results on PCR had relapse (negative predictive value, 100% [CI, 48% to 100%]; P = 0.044). No correlation was found between post-treatment histology and clinical outcome (P > 0.2). CONCLUSIONS: Polymerase chain reaction is highly sensitive and specific when used to confirm the diagnosis of Whipple disease, to identify inconclusive and suspicious cases, and to monitor response to therapy. A negative result on PCR may predict a low likelihood of clinical relapse; a positive test result that remains positive despite therapy may be associated with a poor clinical outcome. Histopathologic evaluation of post-treatment specimens does not predict clinical cure or relapse.

Computed tomography in Whipple disease.
A case of Whipple disease demonstrated on computed tomography (CT) a large mesenteric mass of low density and thickened folds in the jejunum, which was confirmed by barium studies. Retroperitoneal manifestations were absent. The importance of CT in demonstrating the extraintestinal manifestations of Whipple disease is emphasized.

Neurologic presentation of Whipple disease: report of 12 cases and review of the literature.
We report 12 cases of Whipple disease in patients with prominent neurologic symptoms, along with 122 cases of Whipple disease with nervous system involvement reported in the literature. We analyzed the clinical signs and results of additional examinations in 2 groups: the first group included patients with predominantly but not exclusively neurologic signs, and the second included patients with clinically isolated neurologic presentation of the disease. Whipple disease is a multisystemic infectious disease due to Tropheryma whippelii that may present with prominent or isolated symptoms of either the central or the peripheral nervous system. Recent reports stress the importance of polymerase chain reaction (PCR) analysis of cerebrospinal fluid, magnetic resonance imaging (MRI) during follow-up, and prolonged antibiotic therapy with drugs able to cross the blood-brain barrier. Cerebrospinal fluid should be analyzed repeatedly during follow-up, and treatment should be discontinued only when the results of PCR assay performed on cerebrospinal fluid are negative. Other examinations to be done include searching for gastrointestinal tract involvement with multiple duodenal biopsies and searching for systemic involvement with lymph node biopsies, which should be analyzed with light microscopy, electron microscopy, and PCR. When all examinations are negative, if Whipple disease is suspected and a lesion is found on brain MRI, a stereotactic cerebral biopsy should be performed. Treating Whipple disease with long-term trimethoprim-sulfamethoxazole is usually effective, but the use of third-generation cephalosporins in case of incomplete response deserves further attention.

[Whipple disease, initially diagnosed as sarcoidosis].
INTRODUCTION: Whipple disease is a multisystem infectious disease caused by Tropheryma whipplei. We report a case in which an initial diagnosis of sarcoidosis was changed to Whipple disease endocarditis. CASE: Based on clinical, radiographic, endoscopic and histologic findings, this 61-year-old man was diagnosed with sarcoidosis. Initial response to corticotherapy was good, but the patient required 35 mg of prednisone daily. The subsequent onset of clinical and laboratory signs of inflammation cast doubt on the diagnosis. After cardiac ultrasound revealed a mass 1 cm in diameter on the mitral valve, apparently vegetation, we diagnosed culture-negative infective endocarditis and ruled out most possible causes. PCR of a duodenal biopsy sample showed Tropheryma whipplei, thus confirming the diagnosis of Whipple disease, despite normal histological findings. After 3 weeks of intravenous gentamicin and amoxicillin treatment, oral cotrimoxazole was substituted. Follow-up transesophageal ultrasound showed no mitral vegetation. The patient, still under cotrimoxazole, has been off prednisone for 13 months and is completely asymptomatic. CONCLUSION: This case is an illustration of the difficulty in distinguishing Whipple disease from sarcoidosis in practice and of the importance of that distinction.

Intracerebral Whipple disease: unusual location and bone destruction. Case report.
Whipple disease is a rare systemic bacterial infection characterized by migratory polyarthralgia and chronic diarrhea. In 5 to 20% of patients with Whipple disease, the infection may present initially with or eventually develop symptoms related to the central nervous system (CNS). Although CNS involvement is a known feature of systemic Whipple disease, intracerebral mass lesions are uncommon. Mass lesions in these cases are typically deep seated and multifocal. Corticosubcortical regions are unusual sites of CNS involvement in cases of Whipple disease. In the present paper, the authors describe the first case of Whipple disease to feature a single corticosubcortical solid frontoparietal mass lesion that displayed homogeneous contrast enhancement on neuroimaging and was associated with bone destruction of the calvaria. Although CNS involvement has been observed in the form of deep-seated mass lesions in cases of systemic Whipple disease, unusual manifestations should be kept in mind during diagnosis and follow-up review in these patients.
