Eosinophilic Granulomatosis With Polyangiitis Gradually Worsening With Consecutive Pregnancies: A Case Report

This case report elucidates the diagnosis and management of eosinophilic granulomatosis with polyangiitis (EGPA), a form of systemic vasculitis, in a 32-year-old female presenting with progressive dermal, respiratory, and gastrointestinal symptoms following multiple pregnancies. The patient's history of allergic reactions and pregnancies suggested a gradual progression of EGPA, a condition rarely associated with pregnancy. Initial symptoms were misinterpreted as allergic reactions and acute gastroenteritis, delaying the correct diagnosis. Laboratory findings included eosinophilia and elevated immunoglobulin E, while further investigations ruled out other differential diagnoses, such as chronic eosinophilic leukemia. A clinical diagnosis of EGPA was made based on symptom progression, eosinophilia, and mononeuritis multiplex, absent typical granulomatous changes in the skin biopsy. Treatment with high-dose prednisolone and rituximab halted disease progression and improved symptoms, highlighting the critical importance of prompt diagnosis and treatment in preventing irreversible complications. This case emphasizes the need for general physicians to consider pregnancy as a potential trigger for autoimmune diseases like EGPA, especially in patients presenting with multi-symptom allergic reactions and high inflammatory markers.
