Introduction and importance: Churg-Strauss syndrome (CSS) is a rare multisystemic condition characterized by asthma, blood and tissue eosinophilia, and vasculitis. The purpose of this work is to present a detailed overview of CSS, focusing on its epidemiology, clinical symptoms, histological criteria, gastrointestinal involvement, and therapy.
Case presentation: The authors report a case of a 40-year-old woman with CSS who had peripheral eosinophilia, small vessel vasculitis, and bronchial asthma. Diagnosed with symmetric polyarthritis six months ago, experienced abdominal pain, vomiting, and loose faeces. Diagnostic tests revealed CSS with systemic involvement. In addition, we undertake a literature analysis to emphasize essential elements of CSS, such as its rarity and the difficulties in diagnosing and managing it.
Clinical discussion: CSS can cause gastrointestinal symptoms including stomach pain, diarrhoea, mucosal ulcers, rectal bleeding, and bowel perforations. Corticosteroids and immunosuppressives are routinely used in treatment, with caution due to the risks of long-term steroid use. The goal of treatment should be to induce remission while minimizing side effects.
Conclusion: CSS is a rare condition, with an annual incidence of 2.4 per million and a prevalence of 1.3 per 100 000. The illness typically presents with necrotizing vasculitis, extravascular granulomas, and eosinophilic tissue infiltration. CSS is a complex and rare condition that requires high clinical suspicion, especially when patients present with gastrointestinal symptoms in addition to asthma and eosinophilia. This case study adds to our understanding of CSS and emphasizes the significance of a holistic strategy for its management.
