Whipple Disease
Conditions
Brief summary
Whipple's disease is a chronic systemic infection caused by ubiquitous bacterium Tropheryma wipplei on a genetic predisposition which should be considered in patients with recurrent episodes of seronegative arthritis, erosive or not, or inflammatory low back pain, chronic diarrhea, persistent fever, unexplained neurological signs, uveitis, endocarditis, and epithelioid granuloma. Laboratory tests may show malabsorption, erythrocyte sedimentation rate and C-reactive protein elevation, anemia, thrombocytosis, eosinophilia and lymphopenia. None of theses findings is specific and most patients have arthritis or low back pain mimicking rheumatoid arthritis and spondyloarthritis. As the disease is rare, chance for positive polymerase chain reaction testing for Tropheryma whipplei is low in this context.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of patients diagnosed as whipple's disease | Day 0 ( Date of diagnostic) | Diagnosis of Whipple's disease based on * at least one suggestive clinical finding * at least one test detecting T. Whipplei * diagnosis made by a specialist * a dramatic and persistent response to antibiotic therapy * Hydroxychloroquine 200mgx2 plus Doxycycline 100mgx2 * or trimethoprim/sulfamethoxazole 800/160mg x2 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of test performed in each centre | Day 0 (Date of diagnostic) | Number of diagnoses according to tests Patients will be divided into three groups Classic Whipple's disease (CWD), defined as : * duodenal biopsy positive by PAS/immunohistochemistry * or blood positive by PCR Focal Whipple's disease (FWD) * joint fluid positive by PCR * but duodenal biopsy negative by PAS/immunohistochemistry Chronic T. whipplei-associated arthritis (CTWA): chronic arthritis and * duodenal biopsy, stool, or saliva positive by PCR * duodenal biopsy negative by PAS/immunohistochemistry * joint fluid negative by PCR |
