Estimating regional and national cancer incidence in Uganda: a retrospective population-based study, 2013–2017

BackgroundCancer is becoming a major health problem in Uganda. Cancer control requires accurate estimates of the cancer burden for planning and monitoring of the cancer control strategies. However, cancer estimates and trends for Uganda are mainly based on one population-based cancer registry (PBCR), located in Kampala, the capital city, due to a lack of PBCRs in other regions. This study aimed at estimating cancer incidence among the geographical regions and providing national estimates of cancer incidence in Uganda.MethodsA retrospective study, using a catchment population approach, was conducted from June 2019 to February 2020. The study registered all newly diagnosed cancer cases, in the period of 2013 to 2017, among three geographical regions: Central, Western and Eastern regions. Utilizing regions as strata, stratified random sampling was used to select the study populations. Cases were coded according to the International Classification of Diseases for Oncology (ICD-0-03). Data was analysed using CanReg5 and Microsoft Excel.Results11598 cases (5157 males and 6441 females) were recorded. The overall national age-standardized incidence rates (ASIR) were 82.9 and 87.4 per 100,000 people in males and females respectively. The regional ASIRs were: 125.4 per 100,000 in males and 134.6 per 100,000 in females in central region; 58.2 per 100,000 in males and 56.5 per 100,000 in females in Western region; and 46.5 per 100,000 in males and 53.7 per 100,000 in females in Eastern region. Overall, the most common cancers in males over the study period were cancers of the prostate, oesophagus, Kaposi’s sarcoma, stomach and liver. In females, the most frequent cancers were: cervix, breast, oesophagus, Kaposi’s sarcoma and stomach.ConclusionThe overall cancer incidence rates from this study are different from the documented national estimates for Uganda. This emphasises the need to enhance the current methodologies for describing the country’s cancer burden. Studies like this one are critical in enhancing the cancer surveillance system by estimating regional and national cancer incidence and allowing for the planning and monitoring of evidence-based cancer control strategies at all levels.

Health facility readiness to screen, diagnose and manage substance use disorders in Mbale district, Uganda

BackgroundSubstance use disorders (SUD) pose a significant public health problem in Uganda. Studies indicate that integrating mental health services into Primary Health Care can play a crucial role in alleviating the impact of SUD. However, despite ongoing efforts to integrate these services in Uganda, there is a lack of evidence regarding the preparedness of health facilities to effectively screen and manage SUD. Therefore, this study aimed to assess the readiness of health facilities at all levels of the health system in Mbale, Uganda, to carry out screening, diagnosis, and management of SUD.MethodsA health facility-based cross-sectional study was carried out among all the 54 facilities in Mbale district. A composite variable adapted from the WHO Service Availability and Readiness Assessment manual (2015) with 14 tracer indicators were used to measure readiness. A cut-off threshold of having at least half the criteria fulfilled (higher than the cutoff of 7) was classified as having met the readiness criteria. Descriptive analyses were performed to describe readiness scores across various facility characteristics and a linear regression model was used to identify the predictors of readiness.ResultsAmong all health facilities assessed, only 35% met the readiness criteria for managing Substance Use Disorders (SUD). Out of the 54 facilities, 42 (77.8%) had guidelines in place for managing SUD, but less than half, 26 (48%), reported following these guidelines. Only 8 out of 54 (14.5%) facilities had staff who had received training in the diagnosis and management of SUD within the past two years. Diagnostic tests for SUD, specifically the Uri stick, were available in the majority of facilities, (46/54, 83.6%). A higher number of clinical officers working at the health centres was associated with higher readiness scores (score coefficient 4.0,95% CI 1.5–6.5).ConclusionsIn this setting, a low level of health facility readiness to provide screening, diagnosis, and management for substance use disorders was found. To improve health facility readiness for delivery of care for substance use disorders, a frequent inventory of human resources in terms of numbers, skills, and other resources are required in this resource-limited setting.

Burden, risk factors, neurosurgical evacuation outcomes, and predictors of mortality among traumatic brain injury patients with expansive intracranial hematomas in Uganda: a mixed methods study design

BackgroundExpansive intracranial hematomas (EIH) following traumatic brain injury (TBI) continue to be a public health problem in Uganda. Data is limited regarding the neurosurgical outcomes of TBI patients. This study investigated the neurosurgical outcomes and associated risk factors of EIH among TBI patients at Mulago National Referral Hospital (MNRH).MethodsA total of 324 subjects were enrolled using a prospective cohort study. Socio-demographic, risk factors and complications were collected using a study questionnaire. Study participants were followed up for 180 days. Univariate, multivariable, Cox regression analyses, Kaplan Meir survival curves, and log rank tests were sequentially conducted. P-values of < 0.05 at 95% Confidence interval (CI) were considered to be statistically significant.ResultsOf the 324 patients with intracranial hematomas, 80.6% were male. The mean age of the study participants was 37.5 ± 17.4 years. Prevalence of EIH was 59.3% (0.59 (95% CI: 0.54 to 0.65)). Participants who were aged 39 years and above; PR = 1.54 (95% CI: 1.20 to 1.97; P = 0.001), and those who smoke PR = 1.21 (95% CI: 1.00 to 1.47; P = 0.048), and presence of swirl sign PR = 2.26 (95% CI: 1.29 to 3.95; P = 0.004) were found to be at higher risk for EIH. Kaplan Meier survival curve indicated that mortality at the 16-month follow-up was 53.4% (95% CI: 28.1 to 85.0). Multivariate Cox regression indicated that the predictors of mortality were old age, MAP above 95 mmHg, low GCS, complications such as infection, spasticity, wound dehiscence, CSF leaks, having GOS < 3, QoLIBRI < 50, SDH, contusion, and EIH.ConclusionEIH is common in Uganda following RTA with an occurrence of 59.3% and a 16-month higher mortality rate. An increased age above 39 years, smoking, having severe systemic disease, and the presence of swirl sign are independent risk factors. Old age, MAP above 95 mmHg, low GCS, complications such as infection, spasticity, wound dehiscence, CSF leaks, having a GOS < 3, QoLIBRI < 50, ASDH, and contusion are predictors of mortality. These findings imply that all patients with intracranial hematomas (IH) need to be monitored closely and a repeat CT scan to be done within a specific period following their initial CT scan. We recommend the development of a protocol for specific surgical and medical interventions that can be implemented for patients at moderate and severe risk for EIH.

Clinical characteristics and morbidity among hospitalized adults with advanced HIV disease in Uganda during 'test and treat' era.

Nearly four decades after the first case of AIDS was described, the global number of AIDS-related deaths has steadily declined but falls short of the elimination targets, especially in sub-Saharan Africa. Despite interventions to promote early HIV diagnosis and treatment, hospitalization and mortality related to advanced HIV disease (AHD) remains a significant public health problem in Uganda. We assessed the HIV treatment history and causes of hospitalization among in-patients with AHD at a tertiary hospital in Uganda. In this cross-sectional study, pre-hospitalization HIV treatment history and clinical characteristics of HIV-positive in-patients with CD4<200 cells/μL or WHO stage 3 or 4 clinical events were assessed. Descriptive data were summarized using percentages and medians. Among hospitalized adults with AHD from November 2021 to June 2022, 74% (260/353) knew their HIV status prior to hospitalization and 62% (219/353) were ART experienced at presentation. The median time since ART initiation was 28 months (IQR; 2-97). Overall, 73% (258/353) had at least two etiological diagnoses and the majority (non-mutually exclusive) were diagnosed with tuberculosis (61.2%), cryptococcal meningitis (20.7%), mucosal candidiasis (16.1%) and bacterial infections (15%). In conclusion, nearly two-thirds of in-patients with advanced HIV disease were ART experienced prior to hospitalization and tuberculosis was the most common cause of hospitalization. Innovative strategies to strengthen HIV diagnosis, linkage, and retention in HIV care and to increase coverage of TB preventive therapy are urgently needed.

Prevalence, trends and distribution of lifestyle cancer risk factors in Uganda: a 20-year systematic review

BackgroundCancer is becoming an important public health problem in Uganda. Cancer control requires surveillance of lifestyle risk factors to inform targeted interventions. However, only one national Non-Communicable Disease (NCD) risk factor survey has been conducted in Uganda. This review assessed the prevalence, trends and distribution of lifestyle risk factors in Uganda.MethodsThe review identified studies up to January 2019 by searching Medline, Embase, CINAL and Cochrane databases. Further literature was identified from relevant websites and journals; scanning reference lists of relevant articles; and citation searching using Google Scholar. To be eligible, studies had to have been conducted in Uganda, and report prevalence estimates for at least one lifestyle cancer risk factor. Narrative and systematic synthesis was used to analyse the data.ResultsTwenty-four studies were included in the review. Overall, unhealthy diet (88%) was the most prevalent lifestyle risk factor for both males and females. This was followed by harmful use of alcohol (range of 14.3% to 26%) for men, and being overweight (range of 9% to 24%) for women. Tobacco use (range of 0.8% to 10.1%) and physical inactivity (range of 3.7% to 4.9%) were shown to be relatively less prevalent in Uganda. Tobacco use and harmful use of alcohol were more common in males and more prevalent in Northern region, while being overweight (BMI > 25 kg/m2) and physical inactivity were more common in females and more prevalent in Central region. Tobacco use was more prevalent among the rural populations compared to urban, while physical inactivity and being overweight were more common in urban than in rural settings. Tobacco use has decreased overtime, while being overweight increased in all regions and for both sexes.ConclusionThere is limited data about lifestyle risk factors in Uganda. Apart from tobacco use, other lifestyle risk factors seem to be increasing and there is variation in the prevalence of lifestyle risk factors among the different populations in Uganda. Prevention of lifestyle cancer risk factors requires targeted interventions and a multi-sectoral approach. Most importantly, improving the availability, measurement and comparability of cancer risk factor data should be a top priority for future research in Uganda and other low-resource settings.

Widespread exposure to Crimean-Congo haemorrhagic fever in Uganda might be driven by transmission from Rhipicephalus ticks: Evidence from cross-sectional and modelling studies

Crimean-Congo haemorrhagic fever (CCHF) is a widespread tick-borne viral infection, present across Africa and Eurasia, which might pose a cryptic public health problem in Uganda. We aimed to understand the magnitude and distribution of CCHF risk in humans, livestock and ticks across Uganda by synthesising epidemiological (cross-sectional) and ecological (modelling) studies. We conducted a cross-sectional study at three urban abattoirs receiving cattle from across Uganda. We sampled humans (n=478), livestock (n=419) and ticks (n=1065) and used commercially-available kits to detect human and livestock CCHF virus (CCHFV) antibodies and antigen in tick pools. We developed boosted regression tree models to evaluate the correlates and geographical distribution of expected tick and wildlife hosts, and of human CCHF exposures, drawing on continent-wide data. The cross-sectional study found CCHFV IgG/IgM seroprevalence in humans of 10·3% (7·8-13·3), with antibody detection positively associated with reported history of tick bite (age-adjusted odds ratio=2·09 (1·09-3·98)). Cattle had a seroprevalence of 69·7% (65·1-73·4). Only one Hyalomma tick (CCHFV-negative) was found. However, CCHFV antigen was detected in Rhipicephalus (5·9% of 304 pools) and Amblyomma (2·9% of 34 pools) species. Modelling predicted high human CCHF risk across much of Uganda, low environmental suitability for Hyalomma, and high suitability for Rhipicephalus and Amblyomma. Our epidemiological and ecological studies provide complementary evidence that CCHF exposure risk is widespread across Uganda. We challenge the idea that Hyalomma ticks are consistently the principal reservoir and vector for CCHFV, and postulate that Rhipicephalus might be important for CCHFV transmission in Uganda, due to high frequency of infected ticks and predicted environmental suitability.

Intimate partner violence disclosure and associated factors among pregnant women attending a city hospital in South-Western Uganda: a cross-sectional study

BackgroundIntimate partner violence (IPV) during pregnancy is a public health problem in Uganda that negatively impacts maternal and newborn health outcomes. However, IPVdisclosure and associated factors among pregnant women have remained poorly documented in southwestern Uganda. Therefore, this study determined IPV disclosure and associated factors among pregnant women attending a large City hospital.MethodsIn a cross-sectional design, 283 women attending Mbarara City Hospital Antenatal care (ANC) clinic were consecutively recruited into the study. Data was collected using a semi-structured questionnaire. This was administered by the research team and the exercise took over a month. That is; from 7th January 2019 to 7th February 2019. The collected data was entered in STATA, and it was analyzed using chi-square, and univariate logistic regression statistics.ResultsOut of the 283 pregnant women who participated in the study, 199 of them, representing seventy-point three percent (70.3%), had reportedly experienced at least one type of IPV during their current pregnancy. However, nearly fifty percent of those that experienced IPV (49.7%, n = 99) disclosed it to a third party, while the majority disclosed it to their biological family member (66.7%), followed by their friends (55.5%), members of their husband’s family (35.3%), neighbors (12.1%), healthcare providers (9.1%), religious leaders (8.1%), and the police (3.1%). Gravidity, OR = 1.9(95% CI: 1.07–3.31, p = 0.027), parity OR = 1.9(95% CI: 1.08–3.34, p = 0.026) and witnessed IPV OR: 5.4(95% CI: 1.93–14.96; p = 0.001) were significantly associated with IPV disclosure.ConclusionA large proportion of the pregnant women who experienced IPV did not disclose it to any third party. In addition to the above, pregnant women's characteristics seem to have a strong influence on IPV disclosure. Therefore, it is important for healthcare providers to routinely screen for IPV during antenatal care if a high IPV disclosure rate is to be achieved.

Impact of the Sachet Alcohol Ban on Alcohol Availability in Uganda

Alcohol use continues to be a major public health problem in Uganda. This study sought to estimate the availability of sachet alcohol among retail food and beverage establishments in two Ugandan districts (Kampala and Jinja) before and after enactment of the national sachet alcohol ban. Independent observations in 100 establishments were conducted by a pair of trained observers during the peak hours of 7 P.M. to 1 A.M. Using a standardized checklist, observers recorded indications of alcohol availability before and after enactment of the sachet alcohol ban. Availability of (a) alcohol and (b) sachet alcohol were significantly affected by the ban. Before the ban, 69% of all establishments sold alcohol; there was a significant reduction in alcohol availability after enactment of the ban to 43% of the establishments (p < .001). This reduction was observed in off-premise establishments (p < .001), but not in on-premise establishments (p = .710). Additionally, before the sachet alcohol ban, 52% of all establishments sold sachet alcohol; however, there was a significant reduction in sachet availability after enactment of the ban (1.4%, p < .001). Legislation banning the manufacture and sale of sachet alcohol has the potential to reduce sachet availability. Future studies should examine changes in alcohol consumption following the sachet alcohol ban.

Youths\u2019 perceptions of community health workers\u2019 delivery of family planning services: a cross-sectional, mixed-methods study in Nakaseke District, Uganda

BackgroundHigh rates of unintended adolescent pregnancy are a significant health problem in Uganda. To improve access to family planning (FP) services, community-based Village Health Teams (VHTs) are widely employed in Uganda to deliver education and services. However, evaluations of FP programs suggest that mainly older, married women use VHT FP services.MethodsTo better understand youth reluctance to use VHTs, we collected quantitative FP and contraceptive-seeking behavior data from a survey of 250 youths aged 15–25 in randomly selected households in Nakaseke District, which we triangulated with data from 3 focus group discussions (FGDs) (n = 15).ResultsMost respondents received FP services from the formal health sector, not VHTs. Only half had talked to a VHT, but 65% knew that VHTs provide free FP services, and most (82%) felt comfortable talking to VHTs about FP. The main reasons for discomfort were fear that VHTs would violate privacy (mentioned by 60% of those not comfortable), that VHTs would talk to parents (33%), shyness (mentioned by 42% of those ≤18), and fear of being judged (14%). Concern about side effects was the most common reason for not using FP methods. Survey respondents said having VHTs of the same sex was important, particularly those in the youngest age group (OR = 4.45; 95%CI: 1.24, 16.00) and those who were unmarried (OR = 5.02; 95%CI: 2.42, 10.39). However, FGD participants (who were older than survey respondents on average) often preferred older VHTs of the opposite sex, whom they viewed as more professional and trustworthy. Respondents said the primary deciding factors for using VHTs were whether privacy would be respected, the proximity of care, and the respectfulness of care.ConclusionsVHTs are a known source of FP services but not widely used by youth due to privacy and quality of care concerns. VHT messaging and training should increase focus on ensuring privacy, protecting confidentiality, providing respectful care, and addressing concerns about contraceptive side effects. Preferences for VHTs of similar age and sex may be more important for younger adolescents than older youths for whom quality concerns predominate.

Whole-genome sequence analysis of Vibrio cholerae from three outbreaks in Uganda, 2014 - 2016

Background: Cholera remains a serious public health problem in Uganda and Africa. The aim of this study was to provide the complete array of antimicrobial resistance genes, integrative and conjugative elements, virulence genes, pathogenicity islands, plasmids, and insertion sequences in the strains. In addition, this study also aimed to provide a single nucleotide polymorphism (SNP) based phylogenetic analysis of the strains. Methods: In the analysis, both Linux and web-based bioinformatics approaches were used to analyze the study sequences. Databases used included; FastQC, MultiQC, Snippy, PANTHER, PATRIC, Unicycler, ISFinder, Center for Genomic Epidemiology pipelines (i.e. MLST, PlasmidFinder, MyDbFinder, and ResFinder), MashTree and IcyTree. Results: The 10 sequenced strains of Vibrio cholerae were found to carry virulence-associated genes including MakA, ctxA, ctxB, carA, carB, trpB, clpB, ace, toxR, zot, rtxA, ompW, ompR, gmhA, fur, hlyA, and rstR. Also identified were: genes of the Type VI secretion system including vasA-L, vgrG-2, vgrG-3, vipA/mglA, and vipB/mglB; alsD (VC1589), involved in the synthesis of 2,3-butanediol; alsR, involved in the acetate-responsive LysR-type regulation; makA, the flagella-mediated cytotoxin gene; Type VI pilus genes including tcpA-F, tcpH-J, tcpN, tcpP-T, and icmF/vasK; adherence genes acfA-D and IlpA; and quorum sensing system genes luxS and cqsA. Pathogenicity islands identified comprised of VSP-1 and VSP-2, as well as VPI-1 and VPI-2. In addition, strA and B, APH(3'')-I, APH(3'')-Ib, APH(6)-Id, APH(6)-Ic, murA, pare, dfrA1, floR, catB, and catB9 were among the antimicrobial resistance genes found in the sequences. Analysis for SNPs shared among the sequences showed that the sequenced strains shared 218 SNPs and of these, 98 SNPs were missense. Gene enrichment analysis of these SNPs showed enrichment in genes that mediate transmembrane-signaling receptor activity, peptidyl-prolyl cis-trans isomerase activity, and phosphor-relay response regulator activity. Conclusions: This study applied bioinformatics approaches to provide comprehensive genomic analysis of V. cholerae genomes obtained from Uganda.

Cultural responses towards the aftermath of suicide among the Acholi in Northern Uganda.

Suicide is a public health problem in Uganda among indigenous societies, and different societies manage its aftermath differently. To explore how the Acholi in Northern Uganda manage the aftermath of suicide. We conducted a qualitative study in Gulu district, a post-conflict area in Northern Uganda. We conducted a total of four focus group discussions (FGDs) and 12 key informant (KI) interviews. KI interviews were conducted with community leaders, while the FGDs were conducted with members of the general population. We analysed the data by means of Grounded Theory. Our findings indicate that rituals form a large part in managing suicide among the Acholi. Study communities practised distancing (symbolically and physically) as a way of dealing with the threat of suicide. Distancing was organized into two broad themes: affect regulation and securing future generations. It is recommended that public health interventions should utilize cultural institutions in the prevention of suicide.

Treatment and prevention of malaria in pregnancy in the private health sector in Uganda: implications for patient safety.

BackgroundMalaria in pregnancy is a major public health problem in Uganda; and it is the leading cause of anaemia among pregnant women and low birth weight in infants. Previous studies have noted poor quality of care in the private sector. Thus there is need to explore ways of improving quality of care in the private sector that provides almost a half of health services in Uganda.MethodsA survey was conducted from August to October 2014 within 57 parishes in Mukono district, central Uganda. The selected parishes had a minimum of 200 households and at least one registered drug shop, pharmacy or private clinic. Data was collected using a structured questionnaire targeting one provider who was found on duty in each selected private health facility and consented to the study. The main variables were: provider characteristics, previous training received, type of drugs stocked, treatment and prevention practices for malaria among pregnant women. The main study outcome was the proportion of private health facilities who prescribe treatment of fever among pregnant women as recommended in the guidelines.ResultsA total of 241 private health facilities were surveyed; 70.5 % were registered drug shops, 24.5 % private clinics and 5.0 % pharmacies. Treatment of fever among pregnant women in accordance with the national treatment guidelines was poor: 40.7 % in private clinics, decreasing to 28.2 % in drug shops and 16.7 % at pharmacies. Anti-malarial monotherapies sulphadoxine-pyrimethamine and quinine were commonly prescribed, often without consideration of gestational age. The majority of providers (>75 %) at all private facilities prescribed SP for intermittent preventive treatment but artemisinin-based combination therapy was prescribed: 8.3, 6.9 and 8.3 % respectively at drug shops, private clinics and pharmacies for prevention of malaria in pregnancy. Few facilities had malaria treatment guidelines; (44.1 % of private clinics, 17.9 % of drug shops, and 41.7 % at pharmacies. Knowledge of people at risk of malaria, P = 0.02 and availability of malaria treatment guidelines, P = 0.03 were the factors that most influenced correct treatment of fever in pregnancy.ConclusionTreatment of fever during pregnancy was poor in this study setting. These data highlight the need to develop interventions to improve patient safety and quality of care for pregnant women in the private health sector in Uganda.

Perceived Risk of HIV Infection and Associated Factors among Secondary School Students in Wakiso District, Uganda

Introduction. HIV/AIDS remain a major public health problem in Uganda and 4% of individuals aged between 15 and 24 years are living with HIV. Few studies have examined HIV risk perception among adolescents in Uganda.Methods. We conducted a cross-sectional study among 379 secondary school students using multistage sampling techniques. Data were collected using an interviewer-administered questionnaire. Descriptive and logistic regression analyses were conducted.Results. One hundred ninety-one (49.6%) of the respondents perceived themselves to be at risk of contracting HIV, 174 (45.9%) had ever had sex, and 139 (80.4%) had first sexual encounter at 16 years or less. Only 49% of respondents who had sex within 12 months used a condom. Being older than 17 years, knowing someone who died of HIV, early sexual debut, and having ever had sex were associated with perceived risk of contracting HIV. After multivariate analysis, knowledge of someone who died of HIV (Adjusted Odds Ratio (AOR) 16, 95% CI 1.49–171.97) remained statistically significant.Conclusion. Many secondary school students perceived themselves to be at risk of contracting HIV; this perception is associated with knowing someone who died of HIV/AIDS. There is a need to strengthen HIV risk reduction interventions in Wakiso secondary schools.

Prevalence and risk factors associated with tungiasis in Mayuge district, Eastern Uganda

IntroductionTungiasis is an endemic but neglected health problem in Uganda especially in resource poor communities. It is largely affecting rural communities in the Eastern, West Nile and Central regions. This study assessed prevalence and risk factors associated with tungiasis in Mayuge district, Eastern Uganda.MethodsThis was a cross sectional study that used a semi-structured questionnaire and observational checklist to collect quantitative data from 422 households in 12 villages. Prevalence of tungiasis was defined as presence of Tunga penetrans in the skin of any household member at the time of data collection.ResultsThe prevalence of tungiasis was 22.5%. However, a big percentage 41.5% of households were reported to have had T. penetrans in the previous month while 49.5% had T. penetrans for more than one month. Majority (90.5%)of the participants used a pin, needle, or thorn to remove sand flea from infected body parts. Having dirty feet (AOR 3.86, CI (1.76-8.34)), dirty clothes (AOR 3.46, CI (2.00-5.97)), cracked house floor (AOR =6.28, CI (3.28-12.03)), dirty floor (AOR 3.21, CI (1.38-7.46)), littered compounds (AOR= 2.95, CI (1.66-5.26)) and rearing cattle (AOR 2.38, CI (1.28-4.45)) were associated with tungiasis. However, practicing preventive measures (AOR 0.51, CI (0.29-0.90)) was found protective for disease.ConclusionTungiasis is still a prevalent health problem in rural communities in Eastern Uganda due to a number of individual (host) and environmental factors. There is need to increase awareness regarding improvement in sanitation and hygiene to enable communities’ implements interventions for prevention of T. penetrans.

Introducing rapid diagnostic tests for malaria into registered drug shops in Uganda: lessons learned and policy implications.

BackgroundMalaria is a major public health problem in Uganda and the current policy recommends introduction of rapid diagnostic tests for malaria (RDTs) to facilitate effective case management. However, provision of RDTs in drug shops potentially raises a new set of issues, such as adherence to RDTs results, management of severe illnesses, referral of patients, and relationship with caretakers. The main objective of the study was to examine the impact of introducing RDTs in registered drug shops in Uganda and document lessons and policy implications for future scale-up of malaria control in the private health sector.MethodsA cluster-randomized trial introducing RDTs into registered drug shops was implemented in central Uganda from October 2010 to July 2012. An evaluation was undertaken to assess the impact and the processes involved with the introduction of RDTs into drug shops, the lessons learned and policy implications.ResultsIntroducing RDTs into drug shops was feasible. To scale-up this intervention however, drug shop practices need to be regulated since the registration process was not clear, supervision was inadequate and record keeping was poor. Although initially it was anticipated that introducing a new practice of record keeping would be cumbersome, but at evaluation this was not found to be a constraint. This presents an important lesson for introducing health management information system into drug shops. Involving stakeholders, especially the district health team, in the design was important for ownership and sustainability. The involvement of village health teams in community sensitization to the new malaria treatment and diagnosis policy was a success and this strategy is recommended for future interventions.ConclusionIntroducing RDTs into drug shops was feasible and it increased appropriate treatment of malaria with artemisinin-based combination therapy. It is anticipated that the lessons presented will help better implementation of similar interventions in the private sector.

Genetic diversity and population structure of Trypanosoma brucei in Uganda: implications for the epidemiology of sleeping sickness and Nagana.

BackgroundWhile Human African Trypanosomiasis (HAT) is in decline on the continent of Africa, the disease still remains a major health problem in Uganda. There are recurrent sporadic outbreaks in the traditionally endemic areas in south-east Uganda, and continued spread to new unaffected areas in central Uganda. We evaluated the evolutionary dynamics underpinning the origin of new foci and the impact of host species on parasite genetic diversity in Uganda. We genotyped 269 Trypanosoma brucei isolates collected from different regions in Uganda and southwestern Kenya at 17 microsatellite loci, and checked for the presence of the SRA gene that confers human infectivity to T. b. rhodesiense.ResultsBoth Bayesian clustering methods and Discriminant Analysis of Principal Components partition Trypanosoma brucei isolates obtained from Uganda and southwestern Kenya into three distinct genetic clusters. Clusters 1 and 3 include isolates from central and southern Uganda, while cluster 2 contains mostly isolates from southwestern Kenya. These three clusters are not sorted by subspecies designation (T. b. brucei vs T. b. rhodesiense), host or date of collection. The analyses also show evidence of genetic admixture among the three genetic clusters and long-range dispersal, suggesting recent and possibly on-going gene flow between them.ConclusionsOur results show that the expansion of the disease to the new foci in central Uganda occurred from the northward spread of T. b. rhodesiense (Tbr). They also confirm the emergence of the human infective strains (Tbr) from non-infective T. b. brucei (Tbb) strains of different genetic backgrounds, and the importance of cattle as Tbr reservoir, as confounders that shape the epidemiology of sleeping sickness in the region.

Prescription patterns and drug use among pregnant women with febrile Illnesses in Uganda: a survey in out-patient clinics

BackgroundMalaria is a public health problem in Uganda; affecting mainly women and children. Effective treatment has been hampered by over-diagnosis and over-treatment with anti-malarial drugs among patients presenting with fever. In order to understand the effect of drug pressure on sulfadoxine-pyrimethamine (SP) resistance in pregnancy, a sample of pregnant women presenting with fever in out–patient clinics was studied. The main objective was to assess prescription patterns and drug use in pregnancy especially SP; and draw implications on the efficacy of SP for intermittent preventive treatment of malaria in pregnancy (IPTp).MethodsA total of 998 pregnant women with a history of fever were interviewed and blood samples taken for diagnosis of malaria and HIV infections. Data were captured on the drugs prescribed for the current febrile episode and previous use of drugs especially SP, anti-retroviral drugs (ARVs) and cotrimoxazole.ResultsFew pregnant women, 128 (12.8%) were parasitaemic for P.falciparum; and of these, 72 (56.3%) received first-line treatment with Artemether-lumefantrine (Coartem®) 14 (10.9%) SP and 33 (25.8%) quinine. Of the parasite negative patients (non-malarial fevers), 186 (21.4%) received Coartem, 423 (48.6%) SP and 19 (2.1%) cotrimoxazole. Overall, malaria was appropriately treated in 35.5% of cases. Almost all febrile pregnant women, 91.1%, were sleeping under a mosquito net. The majority of them, 911 (91.3%), accepted to have an HIV test done and 92 (9.2%) were HIV positive. Of the HIV positive women, 23 (25.0%) were on ARVs, 10 (10.9%) on cotrimoxazole and 30 (32.6%) on SP. A significant proportion of women, 40 (43.5%), were on both SP and cotrimoxazole. Age and occupation were associated with diagnosis and treatment of malaria and HIV infections.ConclusionThere is inappropriate treatment of malaria and non-malarial fevers among pregnant women in these facilities. This is due to non-adherence to the guidelines. Over-prescription and use of anti-malarial drugs, especially SP may have implications on resistance against SP for malaria prevention in pregnancy. The policy implications of these findings are to evaluate SP efficacy as IPTp; and the need to enforce adherence to the current clinical treatment guidelines.

Integrating TB screening tool in medical clinical records improves TB screening and detection among HIV and AIDS patients; a case TASO Uganda

BackgroundTuberculosis remains a major public health problem in Uganda with an annual incidence of 330 cases of all forms and 136 new smear‐positive cases per 100,000 people per year. The expected case load per year is 102,000 as per WHO 2010 Global Report. The 2010 Global WHO Report ranked Uganda 16th among the 22 TB high‐burden countries. Uganda, like most of Sub‐Saharan Africa, is battling with the dual tuberculosis and HIV/AIDS epidemic. TB stands as the number one killer of HIV/AIDS patients, and the clinical presentation of TB among the dually infected persons changed and this has a bearing on the clinical management and design of public health interventions to respond to the dual epidemic. TASO integrated TB screening tool clinical records to remind clinicians to screen for active TB among under TASO care.MethodologyClinicians complete a section of the clinical record form entitled TB screening by assessing if the patient enrolled for TASO care is symptomatic for TB using a screening tool. Patients who screened positive for one or more signs/symptoms of TB were further investigated to confirm active TB by sputum analysis, chest X‐ray, lymph node aspirates and pleural tap for analysis. Cases with confirmed TB received respective treatment as they continue to attend the usual medical review on appointment.ResultsOverall percentage of patients screened for TB improved from 78% to 96% between fourth quarter, 2011 and first quarter, 2012. Of those screened the percentage of patients with at least one or more positive signs/symptoms of TB increased from 23.3% to 42.5% within the same period TASO Tororo MIS, out of those with a positive screen who took a test, the percentage of patients diagnosed with TB increased from (26/126) 15.9% to (68/192) 35% within the same period.Conclusion/recommendationIntegrating screening tool in clinical record will prompt clinicians to screen for active TB at each clinic visit, allow continuity and quality of TB care, prevent unmasking of TB through immune reconstitution syndrome in patients with lower CD4 cell count initiating ART, and monitors TB investigation results, treatment, progress and outcomes.

Foetal haemoglobin and disease severity in sickle cell anaemia patients in Kampala, Uganda.

BackgroundSickle cell anaemia (SCA) is a major chronic health problem in Uganda. In patients with SCA, the level of foetal haemoglobin (HbF) has been found to be important in influencing the clinical course of the disease. Thus populations with high levels of HbF like those in Saudi Arabia have been described as having a milder clinical course with fewer complications as compared to populations with lower levels. Disease modifying drugs can increase the Hb F levels and modify the presentation of SCA.MethodsThis was a cross sectional study in which we determined foetal haemoglobin levels and examined the relationship between HbF levels and disease severity in SCA patients in Mulago Hospital, Kampala, Uganda. We consecutively enrolled 216 children aged 1 year to 18 years with SCA attending the Sickle Cell Clinic at Mulago Hospital whose guardians had given consent. The history included age at onset of initial symptoms and diagnosis, number of hospitalisations and blood transfusions and other complications of SCA (cardiovascular accidents, avascular hip necrosis and priapism). A detailed physical examination was performed to assess the current state and help describe the disease severity for each patient. Blood samples were drawn for HbF levels. HbF levels ≥10% was defined as high.ResultsOf the 216 children, (80) 37% had HbF levels ≥10%. Significant correlations were observed between HbF level and several clinical parameters independent of age including age at diagnosis (p value 0.013), number of hospitalisations (p value 0.024) and transfusions (p value 0.018) since birth.ConclusionA third of the children with SCA attending the Sickle cell clinic in Mulago Hospital have high HbF levels. Higher HbF level is associated with later onset of symptoms and presentation, and less severe disease characterised by fewer hospitalisations and blood transfusions. We suggest HbF levels should be determined at initial contact for patients with SCA to guide counselling and identify those who may need closer follow up and consideration for disease modifying drugs.
