Equinococose policística na Amazônia oriental brasileira: atualização da casuística

Abstract

By means of epidemiological and clinical-laboratorial approaches was consolidated an update of polycystic echinococcosis in the Eastern Brazilian Amazon, period from 1962 to 2003, including unpublished cases and those already published. In that way, they were identified 40 cases of the disease in referred period, understanding cases coming from the States of Pará and Amapá, Brazil. The width of the ages went from 10 to 72 years and 47.5% belonged to the masculine sex. The liver was the attacked organ (82.5% of the cases). The Echinococcus vogeli (Rausch and Bernstein, 1972), comes as the main agent involved. Starting from the recognition of the importance and of the implications of the handling of the echinococcosis for the tropical area, it is believed that should happen an improvement of the diagnosis, appropriate treatment and of a better registration of the disease.

New Aspects of Neotropical Polycystic ( Echinococcus vogeli ) and Unicystic ( Echinococcus oligarthrus ) Echinococcosis

“…Cures were also reported by Chigot et al (10), who followed a similar course of treatment, including CT scanning, and the patient remained well for at least 3 years. In another series, 1 patient died, but 16 improved after surgery (76).…”

“…The clinical characteristics of polycystic echinococcosis in patients depend on the location of the metacestode as well as the extent of invasion of tissues, particularly the liver (Table 1) (76). Included in that group were 14 cases reported by Orlando Fonseca and Aurelio Costa in 1995 (12).…”

“…In one series of patients, five were treated with albendazole alone, with apparently favorable results (76). The courses of treatment were reportedly for different lengths of time and with different degrees of success.…”

Emergence of Polycystic Neotropical Echinococcosis

“…The disease occurs exclusively in rural areas of the American tropics and often in regions where E. granulosus is not present (33). Most cases are reported from Brazil and Colombia (33,39), but PE is endemic from Nicaragua to Chile (35). Its rising frequency (12 cases from 4 countries in 1979, 72 cases by 1997, and 86 cases from 11 countries as of 1998) shows that human PE is an emerging disease and no longer a medical curiosity (33).…”

Most cases are caused by E. vogeli, but many cases could not be assigned specifi cally to any of the 2 South American echinococcal species because the presence of hooks was not reported (33,39). In an advanced laboratory setting, Echinococcus species can be distinguished by PCR followed by sequencing or restriction fragment length polymorphism analysis (40).…”
