Outbreak of urogenital schistosomiasis in Corsica (France): an epidemiological case study
2016
Summary Background Schistosomiasis is a snail-borne parasitic disease endemic in several tropical and subtropical countries. However, in the summer of 2013, an unexpected outbreak of urogenital schistosomiasis occurred in Corsica, with more than 120 local people or tourists infected. We used a multidisciplinary approach to investigate the epidemiology of urogenital schistosomiasis in Corsica, aiming to elucidate the origin of the outbreak. Methods We did parasitological and malacological surveys at nine potential sites of infection. With the snails found, we carried out snail–parasite compatibility experiments by exposing snails to schistosome larvae recovered from the urine of a locally in…
The macroecology of cancer incidences in humans is associated with large-scale assemblages of endemic infections.
2018
8 pages; International audience; It is now well supported that 20% of human cancers have an infectious causation (i.e., oncogenic agents). Accumulating evidence suggests that aside from this direct role, other infectious agents may also indirectly affect cancer epidemiology through interactions with the oncogenic agents within the wider infection community. Here, we address this hypothesis via analysis of large-scale global data to identify associations between human cancer incidence and assemblages of neglected infectious agents. We focus on a gradient of three widely-distributed cancers with an infectious cause: bladder (~2% of recorded cancer cases are due to Shistosoma haematobium), liv…
Schistosoma haematobium Infection and CD4+ T-cell levels: A cross-sectional study of young South African women
2015
Schistosoma (S.) haematobium causes urogenital schistosomiasis and has been hypothesized to adversely impact HIV transmission and progression. On the other hand it has been hypothesized that HIV could influence the manifestations of schistosomiasis. In this cross-sectional study, we explored the association between urogenital S. haematobium infection and CD4 cell counts in 792 female high-school students from randomly selected schools in rural KwaZulu-Natal, South Africa. We also investigated the association between low CD4 cell counts in HIV positive women and the number of excreted schistosome eggs in urine. Sixteen percent were HIV positive and 31% had signs of urogenital schistosomiasis…
Ultrasonographical aspects of urinary schistosomiasis: Assessment of morphological lesions in the upper and lower urinary tract
1986
Ultrasonographic evaluation of 213 patients with urinary schistosomiasis in different age groups was performed in an endemic area of the Democratic Republic of Congo. The results were compared with 94 age matched controls without urinary schistosomiasis. In patients the bladder showed thickening of the wall, polypoid lesions of the mucosa and bladder wall, calcifications and urinary retention. Urinary tract obstruction, predominantly unilateral, was demonstrated. The lesions increased in severity with the intensity of infection, parallel to an increase in ova excretion. Children aged between 8 and 19 years were most severely affected. Pathological lesions of the upper urinary tract were rar…
Gynecological Manifestations, Histopathological Findings, and Schistosoma-Specific Polymerase Chain Reaction Results Among Women With Schistosoma hae…
2015
Schistosoma haematobium may cause pathology in the urinary and genital tracts. In the urinary tract, morbidity is correlated with intensity of infection, as indicated by the number of eggs excreted in the urine [1]. Up to 75% of women excreting S. haematobium ova in the urine may have ova in the lower genital tract. However, female genital schistosomiasis (FGS) may also occur in the absence of urinary egg excretion [2, 3]. FGS is rarely seen without use of a colposcope and is often overlooked even by those who have this tool. In remote areas, where most patients live, the cost of the equipment, the logistical difficulties associated with light sources, electricity, and clean instruments, as…

Dear Sir,We were pleased to read the recent case report on cervical schistosomiasis (Al-Baghdadi et al. 2014). We would like to add a few important points illustrated by a case presenting with cerv...
The first community-based report on the effect of genital Schistosoma haematobium infection on female fertility.
2009
A cross-sectional study in an Schistosoma haematobium endemic area of rural Zimbabwe examined 483 resident women between the ages of 20 and 49 years who were interviewed about fertility. S. haematobium ova in genital tissue was found to be significantly associated with infertility.
Supplementation with micronutrients and schistosomiasis: systematic review and meta-analysis
2019
Schistosomiasis is a parasitic disease caused by helminths of the genus Schistosoma with two presentations; one intestinal and another urinary; which depend on the specie of Schistosoma. One of the species that can produce intestinal schistosomiasis is Schistosoma mansoni, and the specie that produces urinary schistosomiasis is Schistosoma haematobium. Infection can be aggravated by a deficient nutritional status, which negatively impacts the immune system and increases susceptibility to infection. The main objective of this meta-analysis is to determine if a relationship exists between multimicronutrient supplementation and the reduction of infestation with Schistosoma mansoni and Schistos…
Epidemiological, clinical, diagnostic and economic features of an immigrant population of chronic schistosomiasis sufferers with long-term residence …
2021
Background Schistosomiasis, one of the neglected tropical diseases (NTD) listed by the WHO, is an acute and chronic parasitic disease caused by blood flukes (trematode worms) of the genus Schistosoma. Complications of long-term infestation include liver cirrhosis, bladder tumors and kidney failure. The objective of this study was to carry out a clinical and epidemiological characterization of a schistosomiasis-diagnosed immigrant population with long-term residencein the EU as well as to evaluate the diagnostic methods available to date. Methods and results A total of 61 individuals with Schistosoma infection who received medical attention between June 2002 and June 2016 at the North Metrop…
