Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief:
Overview
[Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].
Differentiating Whipple's disease from other Diseases
Whipple's disease must be differentiated from other diseases that cause malabsorption, chronic diarrhea, joins involvement, and neurologic symptoms.
- Malabsorption with small-intestine involvement (celiac disease, sarcoidosis, and lymphoma)
- Infections such as tuberculosis, endemic fungi (eg, Histoplasma spp), Rhodococcus and HIV infection
- Inflammatory bowel diseases
- Connective tissue diseases
- Neurologic disease
- Addison’s disease
The following diseases have presentations similar to that of Whipple's disease.
The table below summarizes the findings that differentiate fatty causes of chronic diarrhea[1][2][3]
| Cause | Osmotic gap | History | Physical exam | Gold standard | Treatment | |
|---|---|---|---|---|---|---|
| < 50
mOsm per kg |
> 50
mOsm per kg* | |||||
| lactose intolerance | - | + |

|
Lactose breath hydrogen test | Restriction of lactose and maintain calcium and vitamin D intake. |
| Celiac sprue | - | + |
|
Immunoglobulin A (IgA) anti-tissue transglutaminase (TTG) antibody followed by upper endoscopy with biopsy. | Dietary counseling, elimination of gluten in the diet. | |
| Whipple disease | - | + | Upper endoscopy with biopsies of the small intestine for T. whipplei testing (histology with PAS staining, polymerase chain reaction [[[PCR]]] testing, and immunohistochemistry) | Doxycycline and hydroxychloroquine are bactericidal | ||
