ABSTRACT

A 54-year-old man was diagnosed with autoimmune pancreatitis, and treatment was initiated with 40 mg/day prednisolone. Prednisolone was tapered to 5 mg/day, and the treatment was terminated at 3 years and 2 months from initiation. Thereafter, a dry cough started. Chest computed tomography revealed thickening of the bronchial wall and ground-glass opacification in both lungs, with multiple nodules in the right lower lobe. Elevated serum IgG4 levels were detected, and transbronchial lung biopsy revealed IgG4-related respiratory disease. The administration of 30 mg/day prednisolone relieved the cough and improved the lung manifestations, and prednisolone was reduced gradually. Although rare, the recurrence of IgG4-related respiratory disease can occur after steroid maintenance treatment for autoimmune pancreatitis.
