Comprehensive Case Analysis: Diagnosing and Managing Myositis in Newly Diagnosed Systemic Lupus Erythematosus Patients in Indonesia

An 18-year-old female with Systemic Lupus Erythematosus (SLE) in Indonesia presented with symptoms including thigh pain, fever, and diarrhea, and was diagnosed with myositis through a muscle biopsy. Initial tests showed elevated transaminase and creatine kinase levels, positive ANA, and decreased complement levels. Treatment with steroids and hydroxychloroquine led to symptom resolution by the eighth day of hospitalization. This case underscores the importance of early diagnosis and management of myositis, a rare SLE manifestation, to achieve positive outcomes.
