[Minocycline-induced pneumonia and pleurisy--a case report].
A 24-year-old woman had been treated with minocycline (MINO) for acute upper airway infection. Two days after the start of MINO therapy, she developed fever, cough, dyspnea, and bloody sputum. Her chest X-ray film revealed bilateral pleural effusions and butterfly shadow, and chest computed tomography revealed markedly increased density of pulmonary tissue in the central lung fields. Arterial blood gas analysis demonstrated severe hypoxemia. The characteristics of the pleural effusion were exudative. Based on the history of her illness and the chest X-ray findings, in addition to the laboratory findings of leukocytosis with eosinophilia and increased serum IgE, drug-induced pneumonia was suspected. Once the treatment with MINO was discontinued, her symptoms, laboratory data, and chest X-ray findings improved rapidly. Microscopic examination of a transbronchial lung biopsy specimen showed increased alveolar septal thickness with formation of Masson's bodies. Although the result of a lymphocyte stimulation test was negative for MINO, the skin test was positive for immediate response. Because of her clinical course, the possibility of induction by other drugs was excluded. This patient was therefore diagnosed to have MINO-induced pneumonia. To date, ten cases of MINO-induced pneumonia have been reported, but no previous case was associated with pleurisy.
