Resumen:
Cystic echinococcosis (CE) is a zoonoses of worldwide distribution
caused mainly by the metacestode Echinococcus granulosus. In Argentina,
its distribution reaches endemic levels. Objective: The aims of this
study were to investigate the trends in confirmed cases of human CE
recorded in"HospitalPrivadodeComunidad" (HPC) in Mardel Plata city
during a period of 28years (1974-2002) and to study demographic and
clinical characteristics of cases together with epidemiological factors
associated with the disease. Material and method: Clinical records of
operated and/or diagnosed patients were reviewed with regard to this
disease. Official notification (ON) records were used to compare the
MAI (mean annual incidence) of CE between 1998 and 2002 with the MAI of
CE in HPC during the same period. Data analysis was performed using Epi
Info 2000 and the R statistical software. One hundred and fifteen cases
(57.4% women; mean age 61.3+17.1 years) were included in this
retrospective study, 80% of which lived in urban areas. Result: The
average incidence for the period was 1,98 per 100000 inhabitants. Age
groups between 60 and 89 showed the higest MAl. In 76.5% of the cases,
ultrasonography was used to diagnose the disease. Hepatic location was
the most frequently seen. Ninety point four per cent of the total
diagnosed CE patients received any approach due to illness, 47.1%
received surgical treatment and 19.2% pharmacological treatment. The
mean length of hospital stay was 15 days. The average incidence for
period 1997-2001 was 3.6 and 1.3 in HPC and Official Notification
respectively.Conclusion: The average annual incidence of CE could be
under-estimated as it only reflects symptomatic cases. The most
diagnosticated age group was 60-89 years-old. This could be due to the
slow course of development for the CE and coincides with the high
percentage of adult people in the study area. CE infection is closely
related to people with high risk factors such as contaminated soil or
contact with infected dogs with parasit eeggs. Ultrasound alone or in
combination with other techniques is the method most frequently used to
diagnose the diasease.Surgery is the first choice for complicated
cysts. This disease generates a high cost for the hospital and an
important social impact. Although CE is a disease of obligatory
notification in Argentina, not all cases are reported. The permanence of
CE the region is mainly due to the natural transmission of the parasite
in the absence of control and prevention measures. Health authorities
should implement the necessary strategies in the study area.Sponsorships: Fund. Roemmers & UNMdP 15/E353.
