Abdominal cystic echinococcosis in Bangladesh: a hospital-based study

Abstract

Introduction: Cystic echinococcosis (CE) is reported from nearly all geographic areas of Bangladesh, but little information is available on its epidemiologic and clinical features. The aim of this study was to describe the clinical manifestations of hepatic and abdominal CE cases presenting to tertiary referral hospitals in Dhaka, Bangladesh. Methodology: A retrospective study was conducted via chart reviews of hepatic and abdominal CE patients under care at tertiary referral hospitals in Dhaka, Bangladesh, between 2002 and 2011. Age, sex, education level, occupation, urban versus rural residence, drinking water source, history of dog ownership, cyst type and location, and clinical manifestations were recorded for all patients. Results: Of the 130 patients enrolled, 92 (70.8%) were female and 38 (29.2%) were male. The majority of patients were from rural (76.2%) rather than urban (23.8%) areas. All cases were from the northern part of the country, with no cases reported from the south or southeast. Most patients were between 21 and 40 years of age. A total of 119 patients (91.5%) had cysts only in the liver, with the remaining 8.5% having cysts in both the liver and lungs or in the abdominal cavity. Seventy-six (58.5%) of the hepatic cysts were stage CE1, indicating recent infection. Conclusions: Active transmission of Echinococcus granulosus appears to be occurring in Bangladesh, as indicated by the high number of CE1 hepatic cysts seen at tertiary care hospitals. Community ultrasound screening studies are warranted to better define the distribution of cases and risk factors for parasite transmission.

Global Distribution of Alveolar and Cystic Echinococcosis

“…In Bangladesh, CE in humans has been reported previously throughout the country (Karim et al, 2015). In abattoirs of the Comilla and Brahmon Baria region CE was diagnosed in 30% of 433 cattle, 9% of 620 buffaloes, 17% of 460 sheep and 36% of 345 goats (Kabir et al, 2010).…”

“…An old report describes infection in 62.5% of dogs from Bangladesh, with seasonal variation (Islam, 1980). More recently, active transmission of CE appears to be occurring in Bangladesh due to findings from hospitals in Dhaka, Bangladesh, between 2002and 2011(Karim et al, 2015. CE has also been reported in cattle (Islam, 1982;Islam and Rahman, 1975).…”

Caracterización epidemiológica de hidatidosis humana y animal en la Región de Los Ríos, 1999-2009

“…Cabe señalar que la clasificación "agropecuaria", incluye diferentes labores vinculadas a esta categoría, como lo son trabajador agrícola, obrero de lechería y agricultor. Otros estudios también han reportado a las dueñas de casa como las más afectadas por esta enfermedad 23 . La mayor cantidad de casos registrados en las ocupaciones anteriormente mencionadas, tiene su posible explicación en la estrecha relación que existe entre el perro y su propietario, ya que en esta zona el perro no es utilizado preferentemente en labores relacionadas con el pastoreo, sino más bien es utilizado casi exclusivamente en labores de vigilancia de los hogares (observación personal).…”
