title: [Pulmonary edema associated with the Chinese medicine shosaikoto].
abstract: A 45-year-old Japanese woman presented with a high fever, a nonproductive coughing, and severe dyspnea, and was admitted to another hospital. During the week prior to hospitalization, she had been given Shosaikoto for treatment of liver dysfunction of unknown etiology. Mycoplasma pneumonitis was initially suspected, so she was treated with antibiotics (clindamycin and minocycline) and received oxygen therapy. Pulmonary insufficiency worsened rapidly, and she was transferred to our hospital. On admission, a chest roentgenogram revealed bilateral alveolar infiltrates predominantly in the medial lung fields. Furosemide and high-dose methylprednisolone were immediately administered, but hypoxemia increased. When the PaO2 was 55.7 Torr while the patient breathed 100% oxygen, mechanical ventilation with positive end-expiratory pressure (PEEP) was started. Arterial blood-gas values improved dramatically, and the chest roentgenogram became clear. Our diagnosis of noncardiogenic pulmonary edema is based on the chest-roentgenographic findings, infiltration of inflammatory cells as seen in two lung-biopsy specimens and bronchoalveolar lavage fluid, the lack of findings of heart failure on physical examination and electrocardiography, and the good clinical response to PEEP. A positive lymphocyte stimulation test in response to Shosaikoto implicated this non-traditional herbal medicine as an etiologic factor in the non-cardiogenic pulmonary edema. Shosaikoto has been identified as the cause of interstitial pneumonia or eosinophilic pneumonia, but pulmonary edema associated with Shosaikoto has not been previously described. This case suggests that methylprednisolone treatment may be insufficient for Shosaikoto-induced pulmonary edema, and that mechanical ventilation with PEEP is very effective.
