Overview
Plain-Language Overview
Whipple Disease is a rare infection that mainly affects the digestive system, especially the small intestine. It is caused by a bacterium called Tropheryma whipplei. This disease can lead to problems with absorbing nutrients from food, causing symptoms like weight loss, diarrhea, and joint pain. It can also affect other parts of the body, including the heart, brain, and eyes, leading to a variety of symptoms. Because it impacts how the body processes food and nutrients, it can cause serious health issues if not diagnosed and treated properly.
Clinical Definition
Whipple Disease is a chronic systemic infection caused by the gram-positive actinomycete Tropheryma whipplei. It primarily involves the small intestine, where it causes infiltration of the lamina propria by macrophages containing PAS-positive granules, leading to malabsorption. The disease manifests with weight loss, diarrhea, arthralgia, and abdominal pain, but can also involve the central nervous system, heart, and other organs. The pathogenesis involves impaired macrophage function and bacterial persistence. It is a rare but important cause of malabsorption and multisystem symptoms, requiring high clinical suspicion for diagnosis.
