Item Acceptability and Predictors of Uptake of Anti-Retroviral Pre-Exposure Prophylaxis (Prep) among Fishing Communities in Uganda: A Cross-Sectional Discrete Choice Experiment Survey(AIDS and behavior, 2019) Kuteesa, Monica O.; Quaife, Mathew; Biraro, Sam; Katumba, Kenneth R.; Seeley, Janet; Kamali, Anatoli; Nakanjako, DamalieWe used a discrete choice experiment to assess the acceptability and potential uptake of HIV pre-exposure prophylaxis (PrEP) among 713 HIV-negative members of fishing communities in Uganda. Participants were asked to choose between oral pill, injection, implant, condoms, vaginal ring (women), and men circumcision. Product attributes were HIV prevention effectiveness, sexually transmitted infection (STI) prevention, contraception, waiting time, and secrecy of use. Data were analysed using mixed multinomial logit and latent class models. HIV prevention effectiveness was viewed as the most important attribute. Both genders preferred oral PrEP. Women least preferred the vaginal ring and men the implant. Condom use was predicted to decrease by one third among men, and not to change amongst women. Oral PrEP and other new prevention technologies are acceptable among fishing communities and may have substantial demand. Future work should explore utility of multiple product technologies that combine contraception with HIV and other STI prevention.Item Acceptance of Routine Testing for HIV among Adult Patients at the Medical Emergency Unit at a National Referral Hospital in Kampala, Uganda(AIDS and Behavior, 2007) Nakanjako, Damalie; Kamya, Moses; Mayanja-Kizza, Harriet; Freers, Jurgen; Whalen, Christopher; Katabira, EllyHIV testing is an entry point to comprehensive HIV/AIDS prevention and care. In Uganda, Routine Testing and Counseling for HIV (RTC) is not widely offered as part of standard medical care in acute care settings. This study determined the acceptance of RTC in a medical emergency setting at Mulago national referral hospital. We interviewed 233 adult patients who were offered HIV testing. Overall, 83% were unaware of their HIV serostatus and 88% of these had been to a health unit in the previous six months. Of the 208 eligible for HIV testing, 95% accepted to test. Half the patients were HIV infected and 77% of these were diagnosed during the study. HIV testing was highly acceptable and detected a significant number of undiagnosed HIV infections. We recommend adoption of RTC as standard of care in the medical emergency unit in order to scale HIV diagnosis and linkage to HIV/AIDS care.Item Atorvastatin reduces T-cell activation and exhaustion among HIV-infected cART-treated suboptimal immune responders in Uganda: a randomised crossover placebo-controlled trial(Tropical medicine & international health, 2015) Nakanjako, Damalie; Ssinabulya, Isaac; Nabatanzi, Rose; Bayigga, Lois; Kiragga, Agnes; Joloba, Moses; Kaleebu, Pontiano; Kambugu, Andrew D.; Kamya, Moses R.; Sekaly, Rafick; Elliott, Alison; Mayanja-Kizza, HarrietT-cell activation independently predicts mortality, poor immune recovery and non-AIDS illnesses during combination antiretroviral therapy (cART). Atorvastatin showed anti-immune activation effects among HIV-infected cART-naïve individuals. We investigated whether adjunct atorvastatin therapy reduces T-cell activation among cART-treated adults with suboptimal immune recovery.A randomised double-blind placebo-controlled crossover trial, of atorvastatin 80 mg daily vs. placebo for 12 weeks, was conducted among individuals with CD4 increase <295 cells/μl after seven years of suppressive cART. Change in T-cell activation (CD3 + CD4 + /CD8 + CD38 + HLADR+) and in T-cell exhaustion (CD3 + CD4 + /CD8 + PD1 + ) was measured using flow cytometry.Thirty patients were randomised, 15 to each arm. Atorvastatin resulted in a 28% greater reduction in CD4 T-cell activation (60% reduction) than placebo (32% reduction); P = 0.001. Atorvastatin also resulted in a 35% greater reduction in CD8-T-cell activation than placebo (49% vs. 14%, P = 0.0009), CD4 T-cell exhaustion (27% vs. 17% in placebo), P = 0.001 and CD8 T-cell exhaustion (27% vs. 16%), P = 0.004. There was no carry-over/period effect. Expected adverse events were comparable in both groups, and no serious adverse events were reported.Atorvastatin reduced T-cell immune activation and exhaustion among cART-treated adults in a Ugandan cohort. Atorvastatin adjunct therapy should be explored as a strategy to improve HIV treatment outcomes among people living with HIV in sub-Saharan Africa.Item Building clinical pharmacology laboratory capacity in low- and middle-income countries: Experience from Uganda(African Journal of Laboratory Medicine, 2023) Omali, Denis; Buzibye, Allan; Kwizera, Richard; Byakika-Kibwika, Pauline; Namakula, Rhoda; Matovu, Joshua; Mbabazi, Olive; Mande, Emmanuel; Sekaggya-Wiltshire, Christine; Nakanjako, Damalie; Gutteck, Ursula; McAdam, Keith; Easterbrook, Philippa; Kambugu, Andrew; Fehr, Jan; Castelnuovo, Barbara; Manabe, Yukari C.; Lamorde, Mohammed; Mueller, Daniel; Merry, ConceptaResearch and clinical use of clinical pharmacology laboratories are limited in low- and middle-income countries. We describe our experience in building and sustaining laboratory capacity for clinical pharmacology at the Infectious Diseases Institute, Kampala, Uganda. Intervention: Existing laboratory infrastructure was repurposed, and new equipment was acquired. Laboratory personnel were hired and trained to optimise, validate, and develop in-house methods for testing antiretroviral, anti-tuberculosis and other drugs, including 10 high-performance liquid chromatography methods and four mass spectrometry methods. We reviewed all research collaborations and projects for which samples were assayed in the laboratory from January 2006 to November 2020. We assessed laboratory staff mentorship from collaborative relationships and the contribution of research projects towards human resource development, assay development, and equipment and maintenance costs. We further assessed the quality of testing and use of the laboratory for research and clinical care. Lessons learnt: Fourteen years post inception, the clinical pharmacology laboratory had contributed significantly to the overall research output at the institute by supporting 26 pharmacokinetic studies. The laboratory has actively participated in an international external quality assurance programme for the last four years. For clinical care, a therapeutic drug monitoring service is accessible to patients living with HIV at the Adult Infectious Diseases clinic in Kampala, Uganda. Recommendations: Driven primarily by research projects, clinical pharmacology laboratory capacity was successfully established in Uganda, resulting in sustained research output and clinical support. Strategies implemented in building capacity for this laboratory may guide similar processes in other low- and middle-income countries.Item Career development for infection and immunity research in Uganda: a decade of experience from the Makerere University – Uganda Virus Research Institute research and training programme [version 2; peer review: 2 approved](AAS Open Research, 2020) Nakanjako, Damalie; Zalwango, Flavia; Wairagala, Pamela; Luboga, Fiona; Andia Biraro, Irene; Bukirwa, Victoria Diana; Mboowa, Mary Gorrethy; Cose, Steve; Seeley, Janet; Elliott, AlisonThe Makerere University/Uganda Virus Research Institute (UVRI) Centre of Excellence for Infection & Immunity Research and Training (MUII) is a collaborative programme supporting excellence in Infection and Immunity (I&I) research in Uganda. Set up in 2008, MUII aims to produce internationally competitive Ugandan and East African I&I research leaders, and develop human and infrastructural resources to support research and training excellence. We undertook an internal evaluation of MUII’s achievements, challenges and lessons learned between 08-2008 and 12-2019, to inform programmes seeking to build Africa’s health research expertise. Methods: Quantitative data were abstracted from programme annual reports. Qualitative data were obtained in 03-04/2019: a crosssectional evaluation was undertaken among a purposefully selected representative sample of 27 trainees and two programme staff. Qualitative data was analysed according to pre-determined themes of achievements, challenges, lessons learned and recommendations for improvement. Results: By 12-2019, MUII had supported 68 fellowships at master’s- level and above (50% female: 23 Masters, 27 PhD, 15 post-doctoral, three group-leaders) and over 1,000 internships. Fellows reported career advancement, mentorship by experts, and improved research skills and outputs. Fellows have published over 300 papers, secured grants worth over £20m, established over 40 international collaborations, and taken on research and academic leadership positions in the country. Key lessons were: i) Efficient administration provides a conducive environment for high quality research; ii) Institutions need supportive policies for procurement, including provisions for purchases of specific biological research reagents from international manufacturers; iii) Strong international and multidisciplinary collaboration provides a critical mass of expertise to mentor researchers in development; and iv) Mentorship catalyses young scientists to progress from graduate trainees to productive academic researchers, relevant to society’s most pressing health challenges. Conclusions: Sustainable academic productivity can be achieved through efficient operational support, global collaboration and mentorship to provide solutions to Africa’s health challenges.Item Disclosure of Parental HIV Status to Children: Experiences of Adults Receiving Antiretroviral Treatment at an Urban Clinic in Kampala, Uganda(AIDS research and treatment, 2017) Osingada, Charles P.; Okuga, Monica; Nabirye, Rose C.; Sewankambo, Nelson K.; Nakanjako, DamalieLimited data are available on the experiences of parental HIV disclosure to children in Uganda. We conducted a qualitative study comprising sixteen in-depth interviews and four focus group discussions with parents receiving highly active antiretroviral therapy. Analysis was done using Atlas.ti qualitative research software. Back-and-forth triangulation was done between transcripts of the indepth interviews and focus group discussions, and themes and subthemes were developed. Barriers to parents’ disclosure included perceptions that children are too young to understand what HIV infection means and fears of secondary disclosure by the children. Immediate outcomes of disclosure included children getting scared and crying, although such instances often gave way to more enduring positive experiences for the parents, such as support in adherence to medical care, help in household chores, and a decrease in financial demands from the children. Country-specific interventions are needed to improve the process of parental HIV disclosure to children and this should encompass preparation on how to deal with the immediate psychological challenges associated with the parent’s disclosure.Item Doctoral training in Uganda: evaluation of mentoring best practices at Makerere university college of health sciences(BMC Medical Education, 2014) Nakanjako, Damalie; Katamba, Achilles; Kaye, Dan K.; Okello, Elialilia; Kamya, Moses R.; Sewankambo, Nelson; Mayanja-Kizza, HarrietGood mentoring is a key variable for determining success in completing a doctoral program. We identified prevailing mentoring practices among doctoral students and their mentors, identified common challenges facing doctoral training, and proposed some solutions to enhance the quality of the doctoral training experience for both candidates and mentors at Makerere University College of Health Sciences (MakCHS). Methods: This cross-sectional qualitative evaluation was part of the monitoring and evaluation program for doctoral training. All doctoral students and their mentors were invited for a half-day workshop through the MakCHS mailing list. Prevailing doctoral supervision and mentoring guidelines were summarised in a one-hour presentation. Participants were split into two homogenous students’ (mentees’) and mentors’ groups to discuss specific issues using a focus group discussion (FGD) guide, that highlighted four main themes in regard to the doctoral training experience; what was going well, what was not going well, proposed solutions to current challenges and perceived high priority areas for improvement. The two groups came together again and the note-takers from each group presented their data and discussions were recorded by a note-taker. Results: Twelve out of 36 invited mentors (33%) and 22 out of 40 invited mentees (55%) attended the workshop. Mentors and mentees noted increasing numbers of doctoral students and mentors, which provided opportunities for peer mentorship. Delays in procurement and research regulatory processes subsequently delayed students’ projects. Similarly, mentees mentioned challenges of limited; 1) infrastructure and mentors to support basic science research projects, 2) physical office space for doctoral students and their mentors, 3) skills in budgeting and finance management and 4) communication skills including conflict resolution. As solutions, the team proposed skills’ training, induction courses for doctoral students-mentor teams, and a Frequently Asked Questions’ document, to better inform mentors’, mentees’ expectations and experiences. Conclusion: Systemic and infrastructural limitations affect the quality of the doctoral training experience at MaKCHS. Clinical and biomedical research infrastructure, in addition to training in research regulatory processes, procurement and finance management, communication skills and information technology, were highlighted as high priority areas for strategic interventions to improve mentoring within doctoral training of clinician scientists.Item Global Health Leadership Training in Resource-Limited Settings: A Collaborative Approach by Academic Institutions and Local Health Care Programs in Uganda(Human Resources for Health, 2015) Nakanjako, Damalie; Namagala, Elizabeth; Semeere, Aggrey; Kigozi, Joanitor; Sempa, Joseph; Ddamulira, John Bosco; Katamba, Achilles; Biraro, Sam; Naikoba, Sarah; Mashalla, Yohana; Farquhar, Carey; Afya Bora Consortium members; Sewankambo, NelsonDue to a limited health workforce, many health care providers in Africa must take on health leadership roles with minimal formal training in leadership. Hence, the need to equip health care providers with practical skills required to lead high-impact health care programs. In Uganda, the Afya Bora Global Health Leadership Fellowship is implemented through the Makerere University College of Health Sciences (MakCHS) and her partner institutions. Lessons learned from the program, presented in this paper, may guide development of in-service training opportunities to enhance leadership skills of health workers in resource-limited settings.The Afya Bora Consortium, a consortium of four African and four U.S. academic institutions, offers 1-year global health leadership-training opportunities for nurses and doctors. Applications are received and vetted internationally by members of the consortium institutions in Botswana, Kenya, Tanzania, Uganda, and the USA. Fellows have 3 months of didactic modules and 9 months of mentored field attachment with 80% time dedicated to fellowship activities. Fellows’ projects and experiences, documented during weekly mentor-fellow meetings and monthly mentoring team meetings, were compiled and analyzed manually using pre-determined themes to assess the effect of the program on fellows’ daily leadership opportunities.Between January 2011 and January 2015, 15 Ugandan fellows (nine doctors and six nurses) participated in the program. Each fellow received 8 weeks of didactic modules held at one of the African partner institutions and three online modules to enhance fellows’ foundation in leadership, communication, monitoring and evaluation, health informatics, research methodology, grant writing, implementation science, and responsible conduct of research. In addition, fellows embarked on innovative projects that covered a wide spectrum of global health challenges including critical analysis of policy formulation and review processes, bottlenecks in implementation of national HIV early infant diagnosis and prevention of mother-to-child HIV-transmission programs, and use of routine laboratory data about antibiotic resistance to guide updates of essential drug lists.In-service leadership training was feasible, with ensured protected time for fellows to generate evidence-based solutions to challenges within their work environment. With structured mentorship, collaborative activities at academic institutions and local health care programs equipped health care providers with leadership skills.Item High T-cell immune activation and immune exhaustion among individuals with suboptimal CD4 recovery after 4 years of antiretroviral therapy in an African cohort(BMC infectious diseases, 2011) Nakanjako, Damalie; Ssewanyana, Isaac; Mayanja-Kizza, Harriet; Kiragga, Agnes; Manabe, Yukari C.; Nabatanzi, Rose; Kamya, Moses R.; Cao, HuyenAntiretroviral therapy (ART) partially corrects immune dysfunction associated with HIV infection. The levels of T-cell immune activation and exhaustion after long-term, suppressive ART and their correlation with CD4 T-cell count reconstitution among ART-treated patients in African cohorts have not been extensively evaluated.T-cell activation (CD38+HLA-DR+) and immune exhaustion (PD-1+) were measured in a prospective cohort of patients initiated on ART; 128 patient samples were evaluated and subcategorized by CD4 reconstitution after long-term suppressive treatment: Suboptimal [median CD4 count increase 129 (-43-199) cells/μl], N = 34 ], optimal [282 (200-415) cells/μl, N = 64] and super-optimal [528 (416-878) cells/μl, N = 30].Both CD4+ and CD8 T-cell activation was significantly higher among suboptimal CD4 T-cell responders compared to super-optimal responders. In a multivariate model, CD4+CD38+HLADR+ T-cells were associated with suboptimal CD4 reconstitution [AOR, 5.7 (95% CI, 1.4-23, P = 0.014)]. T-cell exhaustion (CD4+PD1+ and CD8+PD1+) was higher among suboptimal relative to optimal (P < 0.001) and super-optimal responders (P < 0.001). T-cell exhaustion was significantly associated with suboptimal responders [AOR, 1.5 (95%CI, 1.1-2.1), P = 0.022].T-cell activation and exhaustion persist among HIV-infected patients despite long-term, sustained HIV-RNA viral suppression. These immune abnormalities were associated with suboptimal CD4 reconstitution and their regulation may modify immune recovery among suboptimal responders to ART.Item Makerere University-Uganda Heart Institute collaborative cardiovascular disease training and research since 1988.(African Health Sciences, 2022-08) Okello, Emmy; Ssemogerere, Lameck; Ssinabulya, Isaac; Kayima, James; Nakanjako, Damalie; Sebatta, Elias; Lubega, Sulaiman; Oketcho, Michael; Mwambu, Tom; Lwabi, Peter; Mijumbi, Cephas; Omagino, JohnBackground: Makerere University College of Health Sciences has been collaborating with the Uganda Heart Institute to build capacity for research, training and clinical care in cardiovascular medicine for the last 34 years to appropriately respond to rising societal needs for advanced cardiovascular care which was lacking before this period. Aim: To describe the major milestones in the MakCHS-UHI cardiovascular training collaboration and chart way for future collaborations. Method: This short communication highlights some of the salient features and important milestones in the collaboration journey of the two institutions. Conclusion: Clinical centres of excellence in specialised fields of health care, such as the Uganda Heart Institute for Cardiology, provide a conducive academic environment for MakCHS clinical scientists to provide high quality evidence-based care to meet societal needs.Item Mentorship needs at academic institutions in resource-limited settings: a survey at Makerere university college of health sciences(BMC Medical Education, 2011) Nakanjako, Damalie; Byakika-Kibwika, Pauline; Kintu, Kenneth; Aizire, Jim; Nakwagala, Fred; Luzige, Simon; Namisi, Charles; Mayanja-Kizza, Harriet; Kamya, Moses R.Mentoring is a core component of medical education and career success. There is increasing global emphasis on mentorship of young scientists in order to train and develop the next leaders in global health. However, mentoring efforts are challenged by the high clinical, research and administrative demands. We evaluated the status and nature of mentoring practices at Makerere University College of Health Sciences (MAKCHS). Methods: Pre-tested, self-administered questionnaires were sent by email to all Fogarty alumni at the MAKCHS (mentors) and each of them was requested to complete and email back the questionnaire. In addition to training level and number of mentors, the questionnaires had open-ended questions covering themes such as; status of mentorship, challenges faced by mentors and strategies to improve and sustain mentorship within MAKCHS. Similarly, open-ended questionnaires were sent and received by email from all graduate students (mentees) registered with the Uganda Society for Health Scientists (USHS). Qualitative data from mentors and mentees was analyzed manually according to the pre-determined themes.Item Parasite-based malaria diagnosis: Are Health Systems in Uganda equipped enough to implement the policy?(BMC Public Health, 2012) Kyabayinze, Daniel J.; Achan, Jane; Nakanjako, Damalie; Mpeka, Betty; Mawejje, Henry; Mugizi, Rukaaka; Kalyango, Joan N.; D’Alessandro, Umberto; Talisuna, Ambrose; Jean-Pierre, Van geertruydenMalaria case management is a key strategy for malaria control. Effective coverage of parasite-based malaria diagnosis (PMD) remains limited in malaria endemic countries. This study assessed the health system's capacity to absorb PMD at primary health care facilities in Uganda. Methods: In a cross sectional survey, using multi-stage cluster sampling, lower level health facilities (LLHF) in 11 districts in Uganda were assessed for 1) tools, 2) skills, 3) staff and infrastructure, and 4) structures, systems and roles necessary for the implementing of PMD. Results: Tools for PMD (microscopy and/or RDTs) were available at 30 (24%) of the 125 LLHF. All LLHF had patient registers and 15% had functional in-patient facilities. Three months’ long stock-out periods were reported for oral and parenteral quinine at 39% and 47% of LLHF respectively. Out of 131 health workers interviewed, 86 (66%) were nursing assistants; 56 (43%) had received on-job training on malaria case management and 47 (36%) had adequate knowledge in malaria case management. Overall, only 18% (131/730) Ministry of Health approved staff positions were filled by qualified personnel and 12% were recruited or transferred within six months preceding the survey. Of 186 patients that received referrals from LLHF, 130(70%) had received pre-referral anti-malarial drugs, none received pre-referral rectal artesunate and 35% had been referred due to poor response to antimalarial drugs. Conclusion: Primary health care facilities had inadequate human and infrastructural capacity to effectively implement universal parasite-based malaria diagnosis. The priority capacity building needs identified were: 1) recruitment and retention of qualified staff, 2) comprehensive training of health workers in fever management, 3) malaria diagnosis quality control systems and 4) strengthening of supply chain, stock management and referral systems.Item Policy development, implementation and evaluation by the AIDS control program in Uganda: a review of the processes(Health Research Policy and Systems, 2013) Tumwesigye, Benson T.; Nakanjako, Damalie; Wanyenze, Rhoda K.; Akol, Zainab; Sewankambo, NelsonThe AIDS Control Program (ACP) in Uganda has spearheaded the national health sector HIV response for the last three decades. ACP has developed, revised and implemented various HIV prevention, care and treatment policies in order to keep interventions relevant to the changing dynamics of the HIV epidemic. However, the ACP team and partners remain concerned about the lengthy policy development processes. This study documented the policy development and revision processes to identify strengths and weaknesses in order to inform adjustments as Uganda embraces the move to ‘zero’ HIV infections. Methods: Data was collected through a review of the relevant policy documents and key informant interviews with the five program officers involved in the recently developed Safe Male Circumcision (SMC) policy and the recently revised HIV Counseling and Testing (HCT) policy. Qualitative data was analyzed manually using predetermined themes. Results: Development and revision of the SMC and HCT policies followed similar processes that included a series of meetings between senior management and a selected technical working group. However, the gaps included: i) inadequate awareness of the existence of national policy development and management guidelines; ii) limited engagement of the policy analysis unit in the policy development/revision processes; iii) inadequate tracking and evaluation of the policies before revision or development of new related policies; iv) lack of specific protocols/ standard operating procedures (SOPs); and, v) limited indigenous funding for the entire policy development processes which contributed to non-adherence to the anticipated timelines.Item Predictors and outcomes of mycobacteremia among HIV-infected smear- negative presumptive tuberculosis patients in Uganda(BMC infectious Diseases, 2015) Nakiyingi, Lydia; Ssengooba, Willy; Nakanjako, Damalie; Armstrong, Derek; Kirenga, Bruce J.; Mayanja-Kizza, Harriet; Joloba, Moses L.; Ellner, Jerrold J.; Dorman, Susan E.; Manabe, Yukari C.Sputum smear microscopy for tuberculosis (TB) diagnosis lacks sensitivity in HIV-infected symptomatic patients and increases the likelihood that mycobacterial infections particularly disseminated TB will be missed; delays in diagnosis can be fatal. Given the duration for MTB growth in blood culture, clinical predictors of MTB bacteremia may improve early diagnosis of mycobacteremia. We describe the predictors and mortality outcome of mycobacteremia among HIV-infected sputum smear-negative presumptive TB patients in a high prevalence HIV/TB setting.Between January and November 2011, all consenting HIV-infected adults suspected to have TB (presumptive TB) were consecutively enrolled. Diagnostic assessment included sputum smear microscopy, urine Determine TB lipoarabinomannan (LAM) antigen test, mycobacterial sputum and blood cultures, chest X-ray, and CD4 cell counts in addition to clinical and socio-demographic data. Patients were followed for 12 months post-enrolment.Of 394 sputum smear-negative participants [female, 63.7%; median age (IQR) 32 (28–39) years], 41/394 (10.4%) had positive mycobacterial blood cultures (mycobacteremia); all isolates were M. tuberculosis (MTB). The median CD4 cell count was significantly lower among patients with mycobacteremia when compared with those without (CD4 31 versus 122 cells/μL, p < 0.001). In a multivariate analysis, male gender [OR 3.4, 95%CI (1.4-7.6), p = 0.005], CD4 count <100 cells/μL [OR 3.1, 95% CI (1.1-8.6), p = 0.030] and a positive lateral flow urine TB LAM antigen test [OR 15.3, 95%CI (5.7-41.1), p < 0.001] were significantly associated with mycobacteremia. At 12 months of follow-up, a trend towards increased mortality was observed in patients that were MTB blood culture positive (35.3%) compared with those that were MTB blood culture negative (23.3%) (p = 0.065). Mycobacteremia occurred in 10% of smear-negative patients and was associated with higher mortality compared with smear-negative patients without mycobacteremia. Advanced HIV disease (CD4 < 100 cells/mm3), male gender and positive lateral flow urine TB LAM test predicted mycobacteremia in HIV-infected smear-negative presumptive TB patients in this high prevalence TB/HIV setting.Item Predictors for MTB Culture-Positivity among HIV-Infected Smear-Negative Presumptive Tuberculosis Patients in Uganda: Application of New Tuberculosis Diagnostic Technology(PLoS ONE, 2015) Nakiyingi, Lydia; Nonyane, Bareng A. S.; Ssengooba, Willy; Kirenga, Bruce J.; Nakanjako, Damalie; Lubega, Gloria; Byakika-Kibwika, Pauline; Joloba, Moses L.; Ellner, Jerry J.; Dorman, Susan E.; Mayanja-Kizza, Harriet; Manabe, Yukari C.The existing World Health Organization diagnostic algorithms for smear-negative TB perform poorly in HIV-infected individuals. New TB diagnostics such as urine TB lipoarabinomannan (LAM) could improve the accuracy and reduce delays in TB diagnosis in HIVinfected smear-negative presumptive TB. We sought to determine predictors for MTB culture- positivity among these patients.Item Prevalence, barriers and factors associated with parental disclosure of their HIV positive status to children: a cross-sectional study in an urban clinic in Kampala, Uganda(BMC Public Health, 2016) Osingada, Charles P.; Okuga, Monica; Nabirye, Rose C.; Sewankambo, Nelson K.; Nakanjako, DamalieBackground: Disclosure of parental HIV status is associated with a number of positive outcomes such as improved adherence to clinic appointments, lower levels of parental anxiety and depression, and mutual emotional support between parents and their children. Very few studies in low-resource settings have addressed the issues of parental disclosure of their HIV status to their children. Methods: A cross-sectional study was conducted among adult parents attending HIV/AIDS prevention, care and treatment clinic at Makerere University Infectious Diseases Institute (IDI), Kampala, Uganda. Participants were interviewed using the Parent Disclosure Interview (PDI) questionnaire which is a standard tool developed specifically for HIV infected parents. Data were analyzed using STATA version 13.1. Results: Of 344 participants, only 37 % had told at least one of their children that they were HIV positive. Barriers to disclosure were fear that children may tell other people about the parent’s HIV status, desire not to worry or upset children and perceptions that children may not understand. Age of the parent, religion and having someone committed to care of the children were positively associated with parental disclosure of their HIV positives status. Attainment of tertiary level of education was negatively associated with parental disclosure of their HIV status. Conclusions: Parental disclosure of a positive HIVstatus to their children is still low in urban Kampala. There is therefore need to develop locally relevant interventions so as to increase rates of parental disclosure of a positive HIV status to their children and thus promote open and honest discussions about HIV/AIDS at family levelItem Prevalence, Severity and Factors Associated with Dental Caries Among School Adolescents in Uganda: A Cross-Sectional Study(Brazilian dental journal, 2020) Ndagire, Barbara; Kutesa, Annet; Ssenyonga, Ronald; Kiiza, Harriet Mayanja; Nakanjako, Damalie; Rwenyonyi, Charles MugishaDental caries is one of the most prevalent diseases in developing countries. However, there is limited data on the prevalence and factors associated with dental caries in Ugandan adolescents. The purpose of the present study was to describe the prevalence, severity of dental caries and to determine the factors associated with the disease among school adolescents in Uganda. A cross sectional study was conducted at two secondary schools from Kampala (n=197) and Mukono (n=209) districts, Uganda. At both schools, random sampling was used to select the participating classes and the 406 adolescents (11-19 years) eligible to participate in the research. Dental caries was examined using the Decayed, Missing and Filled Teeth (DMFT) index, and a questionnaire was used to collect other relevant data in form of an oral interview. The data were analyzed using STATA version 12. The data was declared as survey data and all analyses were done with svy command. The prevalence of caries was determined as a percentage of individuals with DMFT score ≥1. Modified Poisson regression models were utilized to assess the association between prevalence, severity of dental caries and independent variables. The overall prevalence of dental caries was 66.0% and mean DMFT score of 2.18±2.67. Dental caries prevalence and severity were significantly (p<0.05) associated with tooth cleaning device, age and history of previous dental visit. There was a high prevalence and severity of dental caries among adolescents, which emphasizes the urgent need to develop and design appropriate interventions to reduce the disease burden.Item Programme level implementation of malaria rapid diagnostic tests (RDTs) use: outcomes and cost of training health workers at lower level health care facilities in Uganda(BMC Public Health, 2012-04-20) Kyabayinze, Daniel J.; Nakanjako, Damalie; Tibenderana, James K.; Geetruyden, Jean Pierre VanThe training of health workers in the use of malaria rapid diagnostic tests (RDTs) is an important component of a wider strategy to improve parasite-based malaria diagnosis at lower level health care facilities (LLHFs) where microscopy is not readily available for all patients with suspected malaria. This study describes the process and cost of training to attain competence of lower level health workers to perform malaria RDTs in a public health system setting in eastern Uganda. Health workers from 21 health facilities in Uganda were given a one-day central training on the use of RDTs in malaria case management, including practical skills on how to perform read and interpret the test results. Successful trainees subsequently integrated the use of RDTs into their routine care for febrile patients at their LLHFs and transferred their acquired skills to colleagues (cascade training model). A cross-sectional evaluation of the health workers’ competence in performing RDTs was conducted six weeks following the training, incorporating observation, in-depth interviews with health workers and the review of health facility records relating to tests offered and antimalarial drug (AMD) prescriptions pre and post training. The direct costs relating to the training processes were also documented. Overall, 135 health workers were trained including 63 (47%) nursing assistants, a group of care providers without formal medical training. All trainees passed the post-training concordance test with ≥ 80% except 12 that required re-training. Six weeks after the one-day training, 51/64 (80%) of the health workers accurately performed the critical steps in performing the RDT. The performance was similar among the 10 (16%) participants who were peer-trained by their trained colleagues. Only 9 (14%) did not draw the appropriate amount of blood using pipette. The average cost of the one-day training was US$ 101 (range $92-$112), with the main cost drivers being trainee travel and per-diems. Health workers offered RDTs to 76% of febrile patients and AMD prescriptions reduced by 37% six weeks post-training. One-day training on the use of RDTs successfully provided adequate skill and competency among health workers to perform RDTs in fever case management at LLHF in a Uganda setting. The cost averaged at US$101 per health worker trained, with the main cost drivers being trainee travel and per diems. Given the good peer training noted in this study, there is need to explore the cost-effectiveness of a cascade training model for large scale implementation of RDTs.Item Subclinical Atherosclerosis among HIV-Infected Adults Attending HIV/AIDS Care at Two Large Ambulatory HIV Clinics in Uganda(PLOS One, 2014) Ssinabulya, Isaac; Kayima, James; Chris, Longenecker; Luwedde, Mary; Semitala, Fred; Kambugu, Andrew; Ameda, Faith; Bugeza, Sam; Grace, McComsey; Juergen, Freers; Nakanjako, DamalieBackground The increased immune activation and inflammation of chronic HIV-infection and the characteristic dyslipidemias associated with HIV infection and antiretroviral therapy (ART) contribute to an increased risk of atherosclerotic vascular disease among HIV-infected adults. There is an emerging need to understand determinants of cardiovascular disease (CVD) among individuals aging with HIV in sub-Saharan Africa. We determined the prevalence of subclinical atherosclerosis [carotid intima media thickness (CIMT) ≥0.78 mm] and its correlation with traditional CVD risk factors among HIV-infected adults. Methods In a cross-sectional study, HIV-infected adults (ART-naïve and ART-treated) were consecutively selected from patients' enrollment registers at two large HIV clinics at Mulago Hospital, Kampala, Uganda. We measured traditional CVD risk factors including age, biophysical profile, fasting blood sugar and serum lipid profile as well as biomarkers of inflammation. High resolution ultrasound was used to measure common carotid CIMT. Results Of 245 patients, Median age [Interquartile range (IQR)] 37 years (31–43), 168 (69%) were females; and 100 (41%) were ART-treated for at least 7 years. Overall, 34/186 (18%) had subclinical atherosclerosis; of whom 15/108 (14%) were ART-naïve whereas 19/78 (24%) were ART-treated. Independent predictors of subclinical atherosclerosis included age [odds ratio (OR) 1.83 per 5-year increase in age; 95% confidence interval (CI) 1.24–2.69; p = 0.002], body mass index (BMI); OR 1.15; CI 1.01–1.31; p = 0.041 and high low density lipoprotein (LDL) [OR 2.99; CI 1.02–8.78, p = 0.046]. High sensitivity C-reactive protein (hsCRP) was positively correlated with traditional cardio-metabolic risk factors including waist circumference (r = 0.127, p = 0.05), triglycerides (r = 0.19, p = 0.003) and Total Cholesterol: High Density Lipoprotein ratio (TC:LDL) (r = 0.225, p<0.001). Conclusion The prevalence of subclinical atherosclerosis was 18% among HIV-infected adults in Uganda. Traditional CVD risk factors were associated with subclinical atherosclerosis. We recommend routine assessment of traditional CVD risk factors within HIV care and treatment programs in sub-Saharan Africa.Item Towards a definition of male partner involvement in the prevention of motherto- child transmission of HIV in Uganda: a pragmatic grounded theory approach(BMC Health Services Research, 2019) Muwanguzi, Patience A.; Nassuna, Louise K.; Voss, Joachim G.; Kigozi, Joanita; Muganzi, Alex; Ngabirano, Tom Denis; Sewankambo, Nelson; Nakanjako, DamalieMale partner involvement has been shown to increase mothers’ uptake of Prevention of Mother-to-Child Transmission of HIV (PMTCT) and improve maternal and infant HIV treatment outcomes. Currently, male involvement in PMTCT is measured primarily through men’s attendance at HIV testing and counselling which may not be a true reflection of their engagement. This study therefore set out to explore the meaning of male partner involvement and propose a definition and theoretical model of this concept in PMTCT in Uganda. Methods Eight focus group discussions and five in-depth interviews were conducted with couples at three public health facilities and community members in the health facility catchment areas in Uganda. The study employed a grounded theory approach underpinned by the pragmatic philosophical paradigm. Data were analyzed using the constant comparative method, performing three levels of open, axial, and selective coding. Results Of the 61 participants, 29 (48%) were male and the majority 39 (63.9%) were in long term marital relationships, while about half were self-employed 29 (47.5%). Three themes emerged for the meaning of male involvement in PMTCT (a) HIV treatment support (b) economic support and (c) psychosocial support. HIV treatment support included adherence support, couples’ HIV counseling and testing, and clinic attendance during and after pregnancy. Participants expressed that men were engaged in PMTCT when they offered economic support by providing basic needs and finances or when they included their female partners in financial planning for the family. Psychosocial support arose from the female participants who defined male involvement as family support, perceived societal recognition and emotional support. Emotional support also included the absence of harm resulting from women’s disclosure of HIV test results to their male partner. Conclusions This study proposes a new definition for male partner involvement in PMTCT in Uganda. The definition extends beyond men’s clinic attendance and HIV testing and counselling. Further research should seek to develop and validate tools to accurately measure male partner involvement as the next step in the development of interventions to improve PMTCT outcomes.
