山东省基本消灭丝虫病后晚期丝虫病发病情况调查

EPIDEMIOLOGICAL SURVEY ON PATIENTS WITH ADVANCED FILARIASIS IN SHANDONG PROVINCE WITH BANCROFTIAN FILARIASIS BASICALLY ELIMINATED

1984～1988年,在原丝虫病严重流行的滕县、邹县等6个县(市)的252个村庄,发现的丝虫病人1038例中,象皮肿383例,乳糜尿357例,鞘膜积液298例。1983年前发病902例(86.9％);1984年后发病136例(13.1％),其中新发现乳糜尿患者125例,占新发病人的91.9％。结果表明,山东省基本消灭丝虫病后,已基本控制了象皮肿和鞘膜积液的发生,但仍继续出现乳糜尿新病人.因此在基本消灭班氏丝虫病的地区,应重点研究控制新病人和治愈原有病人的有效方法。

This paper reports on the incidence of advanced filariasis after basic elimination of bancroftian filariasis since 1983 in Shandong Province. Investigation was carried out in a population of 166 776 between 1984 and 1988 in 252 villages of Teng Xian and other 5 counties/cities, the erstwhile highly endemic areas. A total of 1038 filariasis patients were found with an average incidence of 0.6%. Among them, 383 were with elephantiasis, 357 with chyluria and 298 with hydrocele. 902 cases (86.9$) who suffered the disease before the elimination of filariasis and 136 cases (13.1%) after it, 125 (91.9%) being chyluria cases. The oldest of the 1 038 cases was 86 years of age and the youngest, 6 years of age. The course of duration as 8~74 years in elephantiasis cases, 82.8% of them (317 cases) had previously lymphangitis and/or lymphadenitis. In the past three years 16.4% (52 cases) suffered from prolonged or intermittent acute lymphangitis and/or lymphadenitis. The results of this survey indicated that, after the basic elimination of filariasis in Shandong Province together with thorough clearance of infection source, elephantiasis and hydrocele persisted while new cases of chyluria continued to develop. Therefore, in such areas more emphasis should be put on the treatment of clinical patients. New patients should be surveyed and old patients be treated actively so as ta reach the goal of eradicating filariasis.
