Prevalence of glucose-6-phosphate dehydrogenase deficiency and its association with Plasmodium falciparum infection among children in Iganga distric in Uganda
BACKGROUND: Glucose-6-phosphate dehydrogenase (G6PD) is a metabolic enzyme involved in the pentose phosphate pathway, its especially important in red blood cell metabolism. Glucose-6-phosphate dehydrogenase deficiency is an X-linked recessive hereditary disease characterised by abnormally low levels of G6PD. About 400 million people worldwide have a deficiency of this enzyme. The remarkable geographic correlation of G6PD deficiency distribution with historical endemicity patterns of malaria has led to suggestions that the two could be linked. Some studies have concluded that G6PD deficiency confers resistance to malaria. OBJECTIVE: To determine the prevalence of G6PD deficiency, and determine its relationship with prevalence and incidence of P. falciparum infection among children in Uganda. METHODS: This was longitudinal study involving 245 children, 135 were actively followed up for 12 months. G6PD status was assessed for using PCR-RFLP method. A thick smear was done to determine presence of plasmodium trophozoites and parasite densities. RESULTS: A total of 245 children between 6 months and 9 years were recruited. Of these 46.5% were males. Overall prevalence for the X-linked G6PD A- mutation was; 79.59% wild type, 12.65% heterozygous and 7.76% homozygous or hemizygous. Among the males 14% were hemizygous. At baseline, 40.8% had asymptomatic P falciparum infection. There was no statistically significant difference in prevalence and incidence rates of malaria infection among the different G6PD genotypes with prevalence among heterozygous, homozygous, and wild type being 29%, 42.6% and 43% respectively (p = 0.11) and incidence among heterozygous and wild type being 0.56 and 0.52 episodes/year (p = 0.5). The heterozygous G6PD A- females had a lower parasite density compared to the wild type (2505 vs 941 parasites/μL; P = 0.024). CONCLUSIONS: This study showed that 20.41% of the population in this part of Uganda carry the G6PD A-mutation, within the range of 15-32% seen in other parts of Africa. P. falciparum infection incidence and prevalence rates are similar among the G6PD genotypes though, once infected, P. falciparum parasite densities are lowest among G6PD A- heterozygous females. This suggests differences in P. falciparum infection rates and severity of disease could be mediated by differences in parasite densities among the different G6PD genotypes
Factors affecting adherence to national malaria treatment guidelines in management of malaria among public healthcare workers in Kamuli District, Uganda
Treatment outcome of the implementation of HIV test and treat policy at The AIDs Support Organization (TASO) Tororo clinic, Eastern Uganda: A retrospective cohort study.
BackgroundUganda has been making progress towards universal HIV test and treat since 2013 and the 2016 test and treat policy was expanded from the 2013 guidelines. The expanded policy was rolled out in 2017 across the country. The treatment outcomes of this new policy have not yet been assessed at program level. The objective of this study was to determine the treatment outcome of the HIV test and treat policy in TASO Tororo Clinic, Eastern Uganda.MethodologyThis was a retrospective cohort study using secondary data. The study involved 580 clients who were newly diagnosed HIV positive in TASO Tororo clinic between June 2017 and May 2018, who were then followed up for ART initiation, retention in care, viral load monitoring and viral load suppression. The data was analyzed using Stat 14.0 version statistical software application.ResultsOf the 580 clients, 93.1%(540) were adults aged ≥20 years. The uptake of test and treat was at 92.4%(536) and 12 months retention was at 78.7% (422). The factors associated with retention in care were a) being counselled before ART initiation, AOR 2.41 (95%CI, 1.56-3.71), b) having a treatment supporter, AOR 1.57 (95%CI, 1.02-2.43) and having an opportunistic infection, AOR 2.99 (95%CI:1.21-7.41). The viral load coverage was 52.4% (221) and viral load suppression rate was 89.1% (197) of clients monitored. Age ConclusionThis study found high uptake of ART under test and treat policy, with very low viral load coverage, and a high viral load suppression rate among those monitored. The study therefore highlights a need to differentiate viral load testing based on the population needs and ensure each client testing positive receives pre-ART initiation counselling so as to improve retention in care
Sexual Behavior among Persons Living with HIV in Uganda: Implications for Policy and Practice
<div><p>Introduction</p><p>HIV epidemics are sustained and propagated by new cases of infection which result from transmission from infected persons to uninfected susceptible individuals. People living with HIV (PLHIV) play a critical role in prevention if they adopt safer sexual behaviors. This study estimated the prevalence of and factors associated with safer sexual behaviors among PLHIV seeking care from civil society organizations (CSOs).</p><p>Methods</p><p>In a cross sectional study PLHIV were interviewed about their sexual practices, use of alcohol, HIV status of their regular sexual partners, desire for more children and about their socio-demographic characteristics. We calculated the proportion of PLHIV who abstained and consistently used condoms in the previous twelve months. Independent associations between safer sex and other variables were estimated using adjusted prevalence ratios (aPR) and their 95% confidence intervals (CI).</p><p>Results</p><p>Of the 939 PLHIV, 54% (508) were either abstaining or using condoms consistently and 291 (31%) desired more children. The prevalence of consistent condom use among the sexually active was 41.3% (300/731). Consistent condom use was higher among PLHIV who: didn't use alcohol (aPR 1.30, CI 1.03–1.63); were educated about re-infection with a new strain of HIV (aPR 1.84, CI 1.08–3.12) and had regular sexual partner who was HIV negative (aPR 1.29, CI 1.05–1.57). Prevalence of abstinence was 22.2% (208/939). Abstinence increased with age from 9.4% among PLHIV <25 years to 40.5% among those >50 years. Abstinence was extremely low (2.5%) among PLHIV who were married.</p><p>Conclusions</p><p>Effective interventions that reduce alcohol consumption among PLHIV are needed to avert HIV transmission, prevent acquisition of new HIV strains and STIs. In addition, strategies are needed to address needs of PLHIV who desire more children.</p></div
