Polymyositis as a cause of malabsorption. A case report

Area of Science:

• Gastroenterology
• Rheumatology
• Internal Medicine

Background:

• Polymyositis and dermatomyositis are inflammatory myopathies.
• Connective tissue diseases can affect multiple organ systems, including the gastrointestinal tract.
• Malabsorption syndrome presents with nutrient deficiencies and digestive disturbances.

Observation:

• A patient with polymyositis presented with symptoms of malabsorption syndrome.
• Radiological imaging revealed significant dilatation of the esophagus and small intestine.
• The patient's condition was characterized by intestinal stasis and bacterial overgrowth.

Findings:

• The malabsorption syndrome in this patient was attributed to bacterial overgrowth secondary to intestinal stasis.
• Polymyositis, similar to dermatomyositis and scleroderma, can involve the small bowel.
• Inflammatory myopathies may lead to gastrointestinal dysmotility and subsequent malabsorption.

Implications:

• This case highlights a rare gastrointestinal manifestation of polymyositis.
• Early recognition of intestinal involvement in polymyositis is crucial for timely management.
• Further research is warranted to understand the mechanisms linking inflammatory myopathies to gastrointestinal dysfunction.
