[Outcome and tendency of late convalescence in icterohemorrhagic leptospirosis]

To elucidate the time of onset and duration of complications of icterohemorrhagic leptospirosis (IL), a clinical course of early and late convalescence was analysed in 170 patients who were followed up for 1.5-9 years. It was found that affection of hepatobiliary, urinary, cardiovascular and nervous systems persisted for a year after the acute disease in 65.3, 67.6, 31.8 and 13.5% patients, respectively. The organ of vision was affected for 1 year in 7.1% patients. A total of 86% patients retained the above disorders in early convalescence (for a year). In early convalescence the author observed development of such diseases as chronic hepatitis, a latent stage of chronic renal failure, myocardiac myocardiodystrophy. Nervous and ocular complications manifested both in early and late convalescence (4-18 months). The complications combined in 66.0% cases, renal dysfunction + hepatic dysfunction being most frequent. Endogenic infection foci activated within 6 months after IL. In 19.4% patients, the pathological process prolonged up to 1.5 years. In 5.3% patients it can last for several years. It is concluded that IL patients should be followed up for 1.5 years, combined pattern of organ affection typical for IL should be taken into account.
