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].
OR
[Disease name] must be differentiated from [[differential dx1], [differential dx2], and [differential dx3].
Differentiating Whipple's disease from other Diseases
- Inflammatory rheumatic diseases
- Malabsorption with small-intestine involvement (celiac disease, sarcoidosis, and lymphoma)
- Addison’s disease
- Connective tissue diseases
- Neurologic diseases
- Whipple's disease must be differentiated from other diseases that cause [malabsorption], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].
- As [disease name] manifests in a variety of clinical forms, differentiation must be established in accordance with the particular subtype. [Subtype name 1] must be differentiated from other diseases that cause [clinical feature 1], such as [differential dx1] and [differential dx2]. In contrast, [subtype name 2] must be differentiated from other diseases that cause [clinical feature 2], such as [differential dx3] and [differential dx4].
Differentiating Whipple's disease from other Diseases
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]

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 | ||
