RESUMO
A 51-year-old woman was referred for evaluation of progressive dyspnea of 3 months- duration. She had received 3 doses of adalimumab for treatment of rheumatoid arthritis prior to the onset of her dyspnea. Her chest examination revealed absent diaphragmatic movement with inspiration. Spirometry showed a severe restrictive defect. Radiologic studies confirmed the diagnosis of bilateral diaphragmatic paralysis. Laboratory and radiologic workup excluded other possible causes of the diagnosis. Adalimumab was discontinued, and she was treated with bilevel positive airway pressure ventilation and intravenous immunoglobulin. Three months later, the diaphragmatic paralysis persisted. This is the second reported case of bilateral diaphragmatic paralysis occurring in a patient who had received adalimumab. Acute neuropathies are rare side effects of tumor necrosis factor-alpha inhibitors.
