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, joins involvement, and neurologic symptoms, such as diseases that causes chronic diarrhea, infections, and connective tissue diseases.
- Malabsorption with small-intestine involvement (celiac disease, sarcoidosis, and lymphoma)
- Inflammatory rheumatic 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

> 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 | ||
