BackgroundIn Uganda, control of intestinal schistosomiasis with preventive chemotherapy is typically focused towards treatment of school-aged children; the needs of younger children are presently being investigated as in lakeshore communities very young children can be infected. In the context of future epidemiological monitoring, we sought to compare the detection thresholds of available diagnostic tools for Schistosoma mansoni and estimate a likely age of first infection for these children.Methods and FindingsA total of 242 infants and preschool children (134 boys and 108 girls, mean age 2.9 years, minimum 5 months and maximum 5 years) were examined from Bugoigo, a well-known disease endemic village on Lake Albert. Schistosome antigens in urine, eggs in stool and host antibodies to eggs were inspected to reveal a general prevalence of 47.5% (CI95 41.1–54.0%), as ascertained by a positive criterion from at least one diagnostic method. Although children as young as 6 months old could be found infected, the average age of infected children was between 3¼–3¾ years, when diagnostic techniques became broadly congruent.ConclusionWhilst different assays have particular (dis)advantages, direct detection of eggs in stool was least sensitive having a temporal lag behind antigen and antibody methods. Setting precisely a general age of first infection is problematic but if present Ugandan policies continue, a large proportion of infected children could wait up to 3–4 years before receiving first medication. To better tailor treatment needs for this younger ageclass, we suggest that the circulating cathodic antigen urine dipstick method to be used as an epidemiological indicator.
BackgroundIn 2012 the WHO formally recognised that infants and preschool children are at significant risk of schistosomiasis and qualify for treatment with praziquantel (PZQ). Targeted surveys determining both the performance and safety of this drug are now needed in endemic areas. We have formally assessed parasitological cure and putative side-effects in a prospective cohort of Schistosoma mansoni-infected children (aged 5 months–7 years old) in lakeshore settings of Uganda.Methodology/Principal FindingsFrom a total of 369 children found to be egg-patent for intestinal schistosomiasis, 305 were followed-up three to four weeks after PZQ treatment and infection status re-assessed. Separately, a previously tested side-effect questionnaire was employed before and 24 hours after PZQ treatment to assess incidence and amelioration of symptoms in young children and their mothers. While the overall observed parasitological cure was 56.4%, a significant difference was found between a sub-set of children who had a history of multiple PZQ treatments (between one and four in an 18 month period), where cure rate was 41.7%, and those who had never received treatment (cure rate was 77·6%). PZQ proved to be safe, with only mild reported side effects which cleared within a month after treatment. Prevalence of reported symptoms was significantly lower in children than in mothers, and fewer side-effects were reported upon subsequent rounds of PZQ treatment.Conclusion/SignificanceOur findings show that PZQ treatment of young children resulted in satisfactory cure rates, and marked reduction in egg-output, with only mild and transient reported side-effects. However, the cure rate is clearly lower in younger children and those with history of previous treatment. Cure rate, but not egg reduction rate, was also lower in children with heavier pre-intervention infection intensity. With chemotherapy now recommended as a long-term strategy for disease control in young children, research into optimising the periodicity of targeted treatment strategies is now crucial.
Two years after the introduction of provider-initiated, opt-out HIV counselling and testing during antenatal care (ANC) in Uganda, HIV testing uptake is still low. This study was carried out to explore pregnant women's experiences of, and views on, the policies for opt-out, and couple HIV testing, and to understand how the policy implementation could be improved in order to increase access to prevention of mother-to-child-transmission (PMTCT) services. The study was conducted at three ANC health facilities at different levels of care in rural eastern Uganda. Data were collected through sit-in observations during ANC and 18 semi-structured interviews with pregnant women receiving ANC, and thereafter analysed using latent content analysis. Pregnant women who received ANC from facilities that provided HIV testing on-site perceived HIV testing as compulsory without actually fully realizing the benefits of HIV testing and PMTCT. No referral for HIV testing or information about testing was given at ANC facilities that lacked HIV testing on-site. A major challenge of couple HIV testing was that pregnant women were made responsible for recruiting their spouses for testing, a precarious dilemma for many women who tried to fulfil health workers' requests without having the power to do so. In order to increase uptake of PMTCT services, the pre-test counselling in groups that precedes the provider-initiated HIV testing should be adjusted to inform women about the benefits of PMTCT. Further, if testing is perceived as compulsory it could potentially deter some women from seeking ANC services. In order to increase HIV testing of male partners new strategies are needed, for example peer-sensitization and male clinics. Moreover, to achieve the desired outcomes of the PMTCT programme, monitoring and evaluation should be built into the programme.
The World Health Organization (WHO) recommends praziquantel mass drug administration (MDA) to control schistosomiasis in endemic regions. We aimed to quantify recent and lifetime praziquantel coverage, and reasons for non-treatment, at an individual level to guide policy recommendations to help Uganda reach WHO goals. Cross-sectional household surveys (n = 681) encompassing 3208 individuals (adults and children) were conducted in 2017 in Bugoto A and B, Mayuge District, Uganda. Participants were asked if they had received praziquantel during the recent MDA (October 2016) and whether they had ever received praziquantel in their lifetime. A multivariate logistic regression analysis with socio-economic and individual characteristics as covariates was used to determine factors associated with praziquantel uptake. In the MDA eligible population (≥5 years of age), the most recent MDA coverage was 48.8%. Across individuals’ lifetimes, 31.8% of eligible and 49.5% of the entire population reported having never taken praziquantel. Factors that improved individuals’ odds of taking praziquantel included school enrolment, residence in Bugoto B and increasing years of village-residency. Not being offered (49.2%) and being away during treatment (21.4%) were the most frequent reasons for not taking the 2016 praziquantel MDA. Contrary to expectations, chronically-untreated individuals were rarely systematic non-compliers, but more commonly not offered treatment.
Abstractobjective To assess health workers' compliance with the procedures set in the focused antenatal care (ANC) guidelines in rural Uganda, Tanzania and Burkina Faso; to compare the compliance within and among the three study sites; and to appraise the logistic and supply of the respective health facilities (HF).methods The cross-sectional study was conducted in the rural HF in three African countries. This descriptive observational study took place in HF in Nouna, Burkina Faso (5), Iganga, Uganda (6) and Rufiji, Tanzania (7). In total, 788 ANC sessions and service provisions were observed, the duration of each ANC service provision was calculated, and the infrastructures of the respective HF were assessed.results Health workers in all HF performed most of the procedures but also omitted certain practices stipulated in the focused ANC guidelines. There was a substantial variation in provision of ANC services among HF within and among the country sites. The findings also revealed that the duration of first visits was <15 min and health workers spent even less time in subsequent visits in all three sites. Reagents for laboratory tests and drugs as outlined in the focus ANC guidelines were often out of stock in most facilities.conclusion Health workers in all three country sites failed to perform all procedures stipulated in the focused ANC guideline; this could not be always explained by the lack of supplies. It is crucial to point out the necessity of the core procedures of ANC repeatedly.
