[Subacute pneumopathy caused by hydrochlorothiazide. Cytologic study of the broncho-alveolar lavage].
We report a case of diffuse interstitial pulmonary disease in a 73 year old woman treated for moderate hypertension for one year with the combination of hydrochlorothiazide (50 mg/day) and Amiloride (5 mg/day). The bronchoalveolar lavage showed a neutrophilia of 23% and a 5.5% eosinophilia. The absence of any other aetiological factor and the favourable outcome on cessation of the sole medication incriminate the latter as an aetiological agent in this interstitial pneumonitis.
