Longevity of circulating cathodic antigens in filter paper dried urine spots.

Objectives: This study aims to determine the temporal stability of circulating cathodic antigens (CCA) in filter paper-based dried urine spot (FP-DUS) samples under varying temperatures condition.

Methods: Urine from 20 children confirmed to have infection using Kato-Katz (at least 1 egg per gram of stool) and Schisto POC-CCA (2+ and 3+) methods were stored in form of FP-DUS and urine at room temperature (RT), 4 °C and -20 °C. Standard urine and FP-DUS Schisto POC-CCA methods were employed to detect CCA in urine and FP-DUS samples respectively, at weeks 4, 8 and 12.

Urogenital schistosomiasis among adult male population in an endemic area of southern Tanzania: a descriptive cross-sectional study.

Background: Urogenital schistosomiasis (UGS) caused by is endemic in Southern Tanzania. The disease has significant implications for both socioeconomic and public health. Because infections with usually peak in childhood, the majority of studies have concentrated on school-aged children leaving other groups such as males which might be continuous reservoir of infection transmission.

Sexual and reproductive health among men with genital schistosomiasis in southern Tanzania: A descriptive study.

Male genital schistosomiasis (MGS) is a significantly neglected condition, and its consequences often receive inadequate attention. The disease is suggested to cause schistosomiasis-induced sexual and reproductive health problems among males. The study was conducted to investigate the prevalence of MGS, sexual and reproductive health problems that could be caused by MGS among adult males in Mtama district.

Accuracy and precision of dried urine spot method for the detection of Schistosoma mansoni circulating cathodic antigens in resource-limited settings.

Background: The World Health Organization recommends the use of Schisto point-of-care circulating cathodic antigens (Schisto POC-CCA) for screening of Schistosoma mansoni as it offers better sensitivity than microscopy. However, there are limitation facing the use of this method including timely availability of the test cassettes. The aim of this study was to determine the reliability of dried urine spot (DUS) method for collection of urine and detection of S.

Dried urine spot method for detection of circulating cathodic antigen in resource-limited settings: a proof of concept study.

Background: Among the challenges in schistosomiasis surveillance and mapping surveys is the lack of a sensitive diagnostic method especially in low transmission setting. Currently, the WHO recommends the use point-of-care circulating cathodic antigen (Schisto POC-CCA) tests for surveillance and mapping of intestinal schistosomiasis. However, Schisto POC-CCA test has its drawbacks, one of which is the timely availability of test kits.

Subclinical vascular damage in Schistosoma spp. endemic regions.

Cardiovascular abnormalities have been described in patients with schistosomiasis. Their true prevalence and clinical features in endemic settings are unknown. The study aimed to assess the prevalence of subclinical cardiovascular damage in a population endemic to schistosomiasis.

Urogenital schistosomiasis: prevalence, knowledge and practices among women of reproductive age in Northern Tanzania.

Objective: To determine the prevalence, knowledge and practices regarding urogenital schistosomiasis among women of reproductive age in Kileo Ward, Mwanga District.

Methods: A cross-sectional study was conducted in the dispensary in Kileo Village, Mwanga District. A pre-tested structured questionnaire was administered to participants to collect information on sociodemographic characteristics and schistosomiasis-related knowledge and practices.

Urogenital schistosomiasis prevalence, knowledge, practices and compliance to MDA among school-age children in an endemic district, southern East Tanzania.

Background: Tanzania has a high prevalence of urogenital schistosomiasis. Praziquantel is administered to school-age children on an annual basis as part of efforts to reduce transmission and morbidity associated with heavy infections. We investigated the prevalence, knowledge, and practices of urogenital schistosomiasis transmission, as well as compliance with mass drug administration (MDA) among schoolchildren in Masasi District.

Prevalence and risk factors of urogenital schistosomiasis among under-fives in Mtama District in the Lindi region of Tanzania.

Introduction: Despite the ongoing intervention for schistosomiasis control among school-age children in the Lindi region of Tanzania, urogenital schistosomiasis continues to be a public health problem, presumably because other at-risk populations are not covered in praziquantel deworming campaigns. Evidence shows that under-fives become infected in their early life hence the need to understand the disease profile and the risk factors for exposure to infection so as to plan effective control strategies in this group. This study examined the prevalence and risk factors of urogenital schistosomiasis among under-fives in the Mtama district, Lindi region of Tanzania.

Persistence of Schistosoma haematobium transmission among school children and its implication for the control of urogenital schistosomiasis in Lindi, Tanzania.

Background: Despite twelve rounds of school-based preventive chemotherapy for schistosomiasis in endemic areas of Tanzania such as Mtama district, Lindi: the burden of Schistosoma haematobium infection has remained highly conceivable due to re-infections. The factors associated with continuity of S.haematobium transmission in Mtama district, Lindi have not been fully established.

Predictors for the uptake of optimal doses of sulfadoxine-pyrimethamine for intermittent preventive treatment of malaria during pregnancy in Tanzania: further analysis of the data of the 2015-2016 Tanzania demographic and health survey and malaria indicator survey.

Background: In Tanzania, the uptake of optimal doses (≥ 3) of sulfadoxine-pyrimethamine for intermittent preventive treatment of malaria (IPTp-SP) during pregnancy has remained below the recommended target of 80%. Therefore, this study aimed to investigate the predictors for the uptake of optimal IPTp-SP among pregnant women in Tanzania.

Methods: This study used data from the 2015-16 Tanzania demographic and health survey and malaria indicator survey (TDHS-MIS).

A systematic review and meta-analysis on the rate of human schistosomiasis reinfection.

While praziquantel mass drug administration is currently the most widely used method in the control of human schistosomiasis, it does not prevent subsequent reinfection hence persistent transmission. Towards schistosomiasis elimination, understanding the reinfection rate is crucial in planning for the future interventions. However, there is scarcity of information on the global reinfection rate of schistosomiasis.

Evaluation of Occurrence, Concentration, and Removal of Pathogenic Parasites and Fecal Coliforms in Three Waste Stabilization Pond Systems in Tanzania.

In Tanzania, waste stabilization ponds (WSPs) are employed to treat wastewater, and effluents are used for urban agricultural activities. The use of untreated or partially treated wastewater poses risks of disease transmission, including parasitic and bacterial infections, to exposed communities. Little is known about the occurrence, concentration, and removal of parasites and fecal coliform (FC) bacteria in WSPs in Tanzania.

In vivo antimalarial activity of extracts of Tanzanian medicinal plants used for the treatment of malaria.

Plants used in traditional medicine have been the source of a number of currently used antimalarial medicines and continue to be a promising resource for the discovery of new classes of antimalarial compounds. The aim of this study was to evaluate in vivo antimalarial activity of four plants; Erythrina schliebenii Harms, Holarrhena pubescens Buch-Ham, Phyllanthus nummulariifolius Poir, and Caesalpinia bonducella (L.) Flem used for treatment of malaria in Tanzania.
