[Causes of recurrence of pulmonary tuberculosis: short and long term results of treatment]. / Prichiny retsidivov tuberkuleza legkikh, blizhaishie i otdalennye rezul'taty lecheniia.

The causes of pulmonary tuberculosis recurrences and efficacy of their treatment have been analyzed for 180 patients with pulmonary tuberculosis. The recurrences arise most often secondary to associated diseases (chronic bronchitis, chronic alcoholism, occupational hazards), in subjects who previously have had focal pulmonary tuberculosis (at the sites of posttuberculous changes). Treatment of the recurrences is longer than that of the primary foci, does not prevent residual changes, is not curative in all the cases.
