Titel:
Successful treatment of refractory interstitial lung disease with cyclophosphamide and pirfenidone in a new onset of juvenile SLE; a case report
Beschreibung:
Introduction and importance: Systemic lupus erythematosus is a systemic immune disease, presented with a broad spectrum of clinical manifestations. The occurrence of interstitial lung disease as the initial manifestation of systemic lupus erythematosus is very rare. Case presentation: We present the case of a 6-year-old girl who presented with symptoms of fatigue, fever, oral ulcers, and dry cough with difficulty breathing. On physical examination, the patient had fever and oral ulcers, in addition of acute phase reactant analysis, positive ANA and double stranded DNA. Chest CT images showed nonspecific interstitial pneumonia + organizing pneumonia pattern, leading to the diagnosis of onset of systemic lupus erythematosus with interstitial lung disease. The patient was treated with steroids and azathioprine for one year, and the radiological and immunological resolution was noted. However, the patient continued to cough, have difficulty breathing, and was readmitted to the hospital due to SLE recurrence after 1 year of follow-up. Despite continued corticosteroid therapy and monthly administration of steroids and cyclophosphamide (CYS) for 6 months, the patient’s respiratory symptoms and chest X-ray results did not improve significantly. The patient was then prescribed a daily regimen of cyclophosphamide and pirfenidone, which was found to be effective in reducing the steroid dose and achieving remission after one year of follow-up. Clinical discussion: Treatment of connective tissue disease-associated interstitial lung disease is difficult due to a lack of treatment data. Conclusion: This case provided evidence of the efficacy of combination therapy of pirfenidone and cyclophosphamide for refractory connective tissue disease-associated interstitial lung disease in young children.
