    Background: Comorbid conditions and adverse drug events are associated with poor treatment outcomes among patients with drug resistant tuberculosis (DR – TB). This study aimed at determining the treatment outcomes of DR – TB patients with poor prognostic indicators in Uganda. Methods: We reviewed treatment records of DR – TB patients from 16 treatment sites in Uganda. Eligible patients had confirmed DR – TB, a treatment outcome in 2014–2019 and at least one of 15 pre-defined poor prognostic indicators at treatment initiation or during therapy. The pre-defined poor prognostic indicators were HIV co infection, diabetes, heart failure, malignancy, psychiatric illness/symptoms, severe anaemia, alcohol use, ciga rette smoking, low body mass index, elevated creatinine, hepatic dysfunction, hearing loss, resistance to fluo roquinolones and/or second-line aminoglycosides, previous exposure to second-line drugs (SLDs), and pregnancy. Tuberculosis treatment outcomes were treatment success, mortality, loss to follow up, and treatment failure as defined by the World Health Organisation. We used logistic and cox proportional hazards regression analysis to determine predictors of treatment success and mortality, respectively. Results: Of 1122 DR – TB patients, 709 (63.2%) were male and the median (interquartile range, IQR) age was 36.0 (28.0–45.0) years. A total of 925 (82.4%) had ≥2 poor prognostic indicators. Treatment success and mortality occurred among 806 (71.8%) and 207 (18.4%) patients whereas treatment loss-to-follow-up and failure were observed among 96 (8.6%) and 13 (1.2%) patients, respectively. Mild (OR: 0.57, 95% CI 0.39–0.84, p = 0.004), moderate (OR: 0.18, 95% CI 0.12–0.26, p < 0.001) and severe anaemia (OR: 0.09, 95% CI 0.05–0.17, p < 0.001) and previous exposure to SLDs (OR: 0.19, 95% CI 0.08–0.48, p < 0.001) predicted lower odds of treatment success while the number of poor prognostic indicators (HR: 1.62, 95% CI 1.30–2.01, p < 0.001), for every additional poor prognostic indicator) predicted mortality. Conclusion: Among DR – TB patients with multiple poor prognostic indicators, mortality was the most frequent unsuccessful outcomes. Every additional poor prognostic indicator increased the risk of mortality while anaemia and previous exposure to SLDs were associated with lower odds of treatment success. The management of anaemia among DR – TB patients needs to be evaluated by prospective studies. DR – TB programs should also optimise DR – TB treatment the first time it is initiated.

    (Tropical medicine and health, 2021-02-19) Bongomin, Felix; Olum, Ronald; Kyazze, Andrew Peter; Ninsiima, Sandra; Nattabi, Gloria; Nakyagaba, Lourita; Nabakka, Winnie; Kukunda, Rebecca; Ssekamatte, Phillip; Kibirige, Davis; Cose, Stephen; Nakimuli, Annettee; Baruch Baluku, Joseph; Andia-Biraro, Irene
    Background: Anemia in pregnancy represents a global public health concern due to wide ranging maternal and neonatal adverse outcomes in all peripartum periods. We estimated the prevalence and factors associated with anemia in pregnancy at a national obstetrics and gynecology referral hospital in Uganda and in addition performed a systematic review and meta-analysis of the overall burden of anemia in pregnancy in Uganda. Methods: We conducted a cross-sectional study among 263 pregnant women attending the antenatal care clinic of Kawempe National Referral Hospital, Kampala, Uganda, in September 2020. Anemia in pregnancy was defined as a hemoglobin level of < 11.0 g/dl and microcytosis as a mean corpuscular volume (MCV) of < 76 fL. We also performed a systematic review (PROSPERO Registration ID: CRD42020213001) and meta-analysis of studies indexed on MEDLINE, Embase, African Journal Online, ClinicalTrials.gov, ICTRP, and the Cochrane Library of systematic review between 1 January 2000 and 31 September 2020 reporting on the prevalence of anemia in pregnancy in Uganda. Results: The prevalence of anemia was 14.1% (n= 37) (95%CI 10.4–18.8), of whom 21 (56.8%) had microcytic anemia. All cases of anemia occurred in the second or third trimester of pregnancy and none were severe. However, women with anemia had significantly lower MCV (75.1 vs. 80.2 fL, p<0.0001) and anthropometric measurements, such as weight (63.3 vs. 68.9kg; p=0.008), body mass index (25.2 vs. 27.3, p=0.013), hip (98.5 vs. 103.8 cm, p=0.002), and waist (91.1 vs. 95.1 cm, p=0.027) circumferences and mean systolic blood pressure (BP) (118 vs 125 mmHg, p=0.014). Additionally, most had BP within the normal range (59.5% vs. 34.1%, p=0.023). The comparison meta-analysis of pooled data from 17 published studies of anemia in pregnancy in Uganda, which had a total of 14,410 pregnant mothers, revealed a prevalence of 30% (95% CI 23–37). Conclusions: Despite our study having a lower prevalence compared to other studies in Uganda, these findings further confirm that anemia in pregnancy is still of public health significance and is likely to have nutritional causes, requiring targeted interventions. A larger study would be necessary to demonstrate potential use of basic clinical parameters such as weight or blood pressure as screening predictors for anemia in pregnancy.

    Cardiovascular risk factors among people with drug-resistant tuberculosis in Uganda
    (BMC, 2022-10-10) Baruch Baluku, Joseph; Nabwana, Martin; Nalunjogi, Joanitah; Muttamba, Winters; Mubangizi, Ivan; Nakiyingi, Lydia; Ssengooba, Willy; Olum, Ronald; Bongomin, Felix; Andia-Biraro, Irene; Worodria, William
    Background Tuberculosis (TB) and its risk factors are independently associated with cardiovascular disease (CVD). We determined the prevalence and associations of CVD risk factors among people with drug-resistant tuberculosis (DRTB) in Uganda. Methods In this cross-sectional study, we enrolled people with microbiologically confirmed DRTB at four treatment sites in Uganda between July to December 2021. The studied CVD risk factors were any history of cigarette smoking, diabetes mellitus (DM) hypertension, high body mass index (BMI), central obesity and dyslipidaemia. We used modified Poisson regression models with robust standard errors to determine factors independently associated with each of dyslipidaemia, hypertension, and central obesity. Results Among 212 participants, 118 (55.7%) had HIV. Overall, 196 (92.5%, 95% confidence interval (CI) 88.0-95.3) had≥1 CVD risk factor. The prevalence; 95% CI of individual CVD risk factors was: dyslipidaemia (62.5%; 55.4–69.1), hypertension (40.6%; 33.8–47.9), central obesity (39.3%; 32.9–46.1), smoking (36.3%; 30.1–43.1), high BMI (8.0%; 5.0–12.8) and DM (6.5%; 3.7–11.1). Dyslipidaemia was associated with an increase in glycated haemoglobin (adjusted prevalence ratio (aPR) 1.14, 95%CI 1.06–1.22). Hypertension was associated with rural residence (aPR 1.89, 95% CI 1.14– 3.14) and previous history of smoking (aPR 0.46, 95% CI 0.21–0.98). Central obesity was associated with increasing age (aPR 1.02, 95%CI 1.00–1.03), and elevated diastolic blood pressure (aPR 1.03 95%CI 1.00–1.06). Conclusion There is a high prevalence of CVD risk factors among people with DRTB in Uganda, of which dyslipidaemia is the commonest. We recommend integrated services for identification and management of CVD risk factors in DRTB.

    Trusted sources of information on COVID-19 vaccines during the pandemic in Uganda:
    (Research squares, 2023-10-17) Oloya, Johnson Nyeko; Alema, Nelson Onira; Okot, Christopher; Olal, Emmanuel; Ikoona, Eric Nzirakaindi; Oyat, Freddy Wathum Drinkwater; Steven, Baguma; Ochula, Denish Omoya; Olwedo, Patrick Odong; Pebolo, Francis Pebalo; Atim, Pamela Okot; Okot, Godfrey Smart; Nantale, Ritah; Aloyo, Judith; Kitara, David Lagoro
    Background. COVID-19 has dramatically impacted communities worldwide, especially in developing countries. To successfully control the COVID-19 pandemic, more than 80% vaccination coverage was required, and the flow of correct information to the population was critical. However, misinformation and disinformation could impact this, increasing COVID-19 vaccine hesitancy in some communities. Several studies have assessed the effect of misinformation and disinformation on COVID-19 vaccine acceptance and other responses to the pandemic in the African continent. Thus, the most trusted sources of information on COVID-19 vaccines to the population is critical for successfully managing and controlling the pandemic. This study aimed to assess the most trusted sources of information on COVID-19 vaccines during the pandemic in northern Uganda. Methods. We conducted a cross-sectional study on 587 adult population members in northern Uganda. Stratified and systematic sampling methods were used for selecting participants from twenty-four health facilities in the Acholi subregion. Data were collected using an interviewer-administered questionnaire with an internal validity of Cronbach's α=0.72. A local IRB approved the study, and Stata version 18 was used for data analysis. A Pearson Chi-square (χ2) analysis was conducted to assess the association between trusted sources of information on COVID-19 vaccines among study participants and selected independent variables. Fisher's exact test assessed association when cell value following crosstabulation was ≤5. A P-value <0.05 was used as evidence for an association between the trusted sources of information and independent variables. All results were presented as frequencies and proportions and Chi-square or Fisher's exact test P-values at 95% Confidence Intervals (CI). Results: In a study of 587, most participants were males, 335(57.1%), in the age group of 25-34 years, 180(31.4%), and the most trusted source of information on COVID-19 vaccines were the traditional media sources such as Televisions, Radios, and Newspapers, 349(33.6%). There was no significant association between sex and sources of information on COVID-19 vaccines. However, by age group population, it was significantly associated with internet use (14.7% versus 85.3%; p=0.02), information from family members (9.4% versus 90.6%; p<0.01), and the Government/Ministry of Health (37.9% versus 62.1%; p<0.01). In addition, it was significantly associated with internet use (32.2% versus 67.8%; p=0.03), healthcare providers (32.5% versus 67.5%; p<0.018), the Government/Ministry of Health (31.1% versus 68.9%; p<0.01), and scientific articles (44.7% versus 55.3%; p<0.01) in healthcare workers compared to non-health workers. Conclusion. The most substantial finding from our study was that the most trusted sources of information on COVID-19 vaccines in northern Uganda were Television, Radio, and Newspapers. There were no significant differences in the most trusted sources of information on COVID-19 vaccines between the sexes but significant differences by age groups and occupations, with the younger age groups and non-healthcare workers having more trust in TVs, Radios, and Newspapers. For effective management of an epidemic, there is a need for accurate communication so that misinformation, disinformation, and malinformation do not disrupt the flow of information to communities.

    Impact of high baseline Aspergillus-specific IgG levels on weight and quality-of-life outcomes of patients with chronic pulmonary aspergillosis
    (Medical Mycology, 2020-04-02) Bongomin, Felix; Garcez, Tomaz; Denning, David W.
    This study aimed to evaluate the impact of quantitative baseline Aspergillus-specific immunoglobulin G (IgG) serum levels on weight changes of patients with chronic pulmonary aspergillosis (CPA) under antifungal treatment. We retrospectively reviewed data of patients diagnosed with CPA between April 2015 and March 2018 at the National Aspergillosis Centre (Manchester, UK). All patients were on continued antifungal treat ment for 12 months. Data on Aspergillus-specific IgG levels, St George’s quality of life (SGQoL) variables and weight at baseline, 6 months and 12 months were extracted. We defined a high serum Aspergillus-specific IgG as ≥ 200 mg/l (Group A) and low level < 200 mg/l (Group B). Forty-nine patients (37 male; 12 female), median age 65 years (range: 29–86) were studied. Overall, 33% (n = 16) of the patients were in Group A. The baseline characteristics between the two groups were similar. The median Charlson comorbidity index was 4 (range: 0–5) and 3 (range: 0–9) for Group A and Group B, respectively (P = .543). There was a sustained decline in median Aspergillus IgG levels from baseline, through 6 month to 12 months of continues therapy from 170 (range: 20–1110) to 121 (range: 20–1126), and finally 107 (15–937) mg/l, respectively (P < .001). Group A patients gained more weight at 6 months (9/15 [60%] vs. 7/33 [21%], P = .012) and at 12 months of treatment (9/15 [60%] vs. 7/33 [22%]), and more patients in Group B lost weight ((13/33 [41%] vs. 1/15 [7%]), P = .015). However, there was no difference in QoL outcomes across groups at 6 (P = .3) and 12 (P = .7) months. A very high Aspergillus IgG may confer a higher likelihood of weight gain as a key, objective marker of clinical response, if patients can tolerate 12 months of antifungal therapy.

    Medical Mycology dissertation topics require prioritisation among Postgraduate Microbiology trainees of Makerere University, Uganda
    (International Society for Infectious Diseases, 2022-04-25) Achan, Beatrice; Mboowa, Gerald; Kwizera, Richard; Kateete, David P.; Kajumbulaa, Henry; Bongomin, Felix
    Background: As elsewhere worldwide, there is an increasing burden of fungal diseases in Uganda. However, expertise in medical mycology (the study of fungal diseases of medical importance) among clinicians and laboratory personnel remains low. Objective: This study sought to determine the proportion of dissertations on medical mycology among postgraduate medical microbiology trainees at the College of Health Sciences, Makerere University, Uganda. Methods: We retrospectively reviewed the topics of dissertations submitted to the Departments of Medical Microbiology and Immunology & Molecular Biology from 2011 through 2018. The proportion of dissertation topics on medical mycology was analysed using descriptive statistics. Results: A total of 152 dissertations were retrieved. Of these, only 5 (3.3%) were on medical mycology compared to bacteriology (50.7%, n = 77), virology (27.6%, n = 42), parasitology (14.5%, n = 22) and immunology (4.0%, n = 6). Of the 5 dissertations on fungal diseases, the distribution was as follows: cryptococcal meningitis (40%, n = 2), Candidiasis (20%, n = 1), superficial mycoses (20%, n = 1) and other invasive fungal diseases (20%, n = 1). The most common method that was used for studying the fungal diseases was culture 60%, n = 3. Conclusion: There is limited research on medical mycology among the postgraduate medical microbiology trainees of Makerere University, Uganda

    Structural validity and reliability of the integrated conflict and violence scale
    (Taylor & Francis, 2009-09-07) Mutto, Milton; Lawoko, Stephen; Bangdiwala, Shrikant
    The study validated structure stability, reliability and sub-scale distinctiveness of integrated conflict and violence scale (ICVS) and was cross-sectional; war-affected grade 5 school children participated. ICV internal factorial validity and reliability were evaluated; eigenvalue size and scree plots were used for factor selection. A variable retention factor load threshold of 40.30 was used: Cronbach’s a tests confirmed reliability increments. Pair-wise Pearson correlation tests evaluated sub-scale distinctiveness. Gulu University granted ethical clearance. A total of 280 grade 5 children from 50 primary schools participated: 53% of them were males. Two factors accounted for 100% of variability in attitudes; 18 variables were retained. Expelled variables were: ‘If I catch some one stealing my sugar cane I will fight’ and ‘a bully should be forgiven’. Sub-scale internal consistency reliability coefficients were 0.73 and 0.65, respectively and distinctiveness correlation coefficient was 70.06. The ICVS was validated using standard criteria. Emerging two-factor scale has acceptable psychometric properties especially factorial structure, internal consistency and sub-scale distinctiveness.

    COVID-19 vaccine acceptance among high-risk populations in Uganda
    (Therapeutic Advances in Infectious Disease, 2021) Bongomin, Felix; Olum, Ronald; Andia-Biraro, Irene; Nakwagala, Frederick Nelson; Hudow Hassan, Khalid; Nassozi, Dianah Rhoda; Kaddumukasa, Mark; Byakika-Kibwika, Pauline; Kiguli, Sarah; Kirenga, Bruce J.
    Background: Immunization is an important strategy for controlling the COVID-19 pandemic. COVID-19 vaccination was recently launched in Uganda, with prioritization to healthcare workers and high-risk individuals. In this study, we aimed to determine the acceptability of COVID-19 vaccine among persons at high risk of COVID-19 morbidity and mortality in Uganda. Methods: Between 29 March and 14 April 2021, we conducted a cross-sectional survey consecutively recruiting persons at high risk of severe COVID-19 (diabetes mellitus, HIV and cardiovascular disease) attending Kiruddu National Referral Hospital outpatient clinics. A trained research nurse administered a semi-structured questionnaire assessing demographics, COVID-19 vaccine related attitudes and acceptability. Descriptive statistics, bivariate and multivariable analyses were performed using STATA 16. Results: A total of 317 participants with a mean age 51.5±14.1years were recruited. Of this, 184 (60.5%) were female. Overall, 216 (70.1%) participants were willing to accept the COVID-19 vaccine. The odds of willingness to accept COVID-19 vaccination were four times greater if a participant was male compared with if a participant was female [adjusted odds ratio (AOR): 4.1, 95% confidence interval (CI): 1.8–9.4, p=0.00]. Participants who agreed (AOR: 0.04, 95% CI: 0.01–0.38, p=0.003) or strongly agreed (AOR: 0.04, 95% CI: 0.01–0.59, p=0.005) that they have some immunity against COVID-19 were also significantly less likely to accept the vaccine. Participants who had a history of vaccination hesitancy for their children were also significantly less likely to accept the COVID-19 vaccine (AOR: 0.1, 95% CI: 0.01–0.58, p=0.016). Conclusion: The willingness to receive a COVID-19 vaccine in this group of high-risk individuals was comparable to the global COVID-19 vaccine acceptance rate. Increased sensitization, myth busting and utilization of opinion leaders to encourage vaccine acceptability is recommended.

    Nodding syndrome in Ugandan children—clinical features, brain imaging and complications: a case series
    (BMJ Open, 2013-04-08) Idro, Richard; Opoka, Robert Opika; Aanyu, Hellen T; Piloya-Were, Theresa; Namusoke, Hanifa; Musoke, Sarah Bonita; Nalugya, Joyce; Bangirana, Paul; Mwaka, Amos Deogratius; White, Steven; Chong, Kling; Atai-Omoruto, Anne D; Mworozi, Edison; Nankunda, Jolly; Kiguli, Sarah; Aceng, Jane Ruth; Tumwine, James K; Kakooza-Mwesige, Angelina
    Objectives: Nodding syndrome is a devastating neurological disorder of uncertain aetiology affecting children in Africa. There is no diagnostic test, and risk factors and symptoms that would allow early diagnosis are poorly documented. This study aimed to describe the clinical, electrophysiological and brain imaging(MRI) features and complications of nodding syndrome in Ugandan children. Design: Case series. Participants: 22 children with nodding syndrome brought to Mulago National Referral Hospital for assessment. Outcome measures: Clinical features, physical and functional disabilities, EEG and brain MRI findings and a staging system with a progressive development of symptoms and complications. Results: The median age of symptom onset was 6 (range 4–10) years and median duration of symptoms was 8.5 (range 2–11) years. 16 of 22 families reported multiple affected children. Physical manifestations and complications included stunting, wasting, lip changes and gross physical deformities. The bone age was delayed by 2 (range 1–6) years. There was peripheral muscle wasting and progressive generalised wasting. Four children had nodding as the only seizure type;18 in addition had myoclonic, absence and/or generalised tonic–clonic seizures developing 1–3 years after the onset of illness. Psychiatric manifestations included wandering, aggression, depression and disordered perception. Cognitive assessment in three children demonstrated profound impairment. The EEG was abnormal in all, suggesting symptomatic generalised epilepsy in the majority. There were different degrees of cortical and cerebellar atrophy on brain MRI, but no hippocampal changes. Five stages with worsening physical, EEG and brain imaging features were identified: a prodrome, the development of head nodding and cognitive decline, other seizure types, multiple complications and severe disability. Conclusions: Nodding syndrome is a neurological disorder that may be characterised as probably symptomatic generalised epilepsy. Clinical manifestations and complications develop in stages

    Cor pulmonale complicating chronic pulmonary aspergillosis with fatal consequences: Experience from Uganda
    (Medical mycology case reports, 2019-07-04) Bongomin, Felix; Kwizera, Richard; Atukunda, Angella; Kirengaa, Bruce J.
    Cor pulmonale is a rare complication of pulmonary aspergillosis (CPA). A 45-year-old Ugandan male with a history of recurrent community-acquired pneumonias was admitted with symptoms of progressive difficulty in breathing, chronic productive cough, non-exertional left sided chest pain and progressive weight loss occurring over a 12-month period. Chest CT scan and echocardiography confirmed the diagnosis of CPA with an asper gilloma complicating bronchiectasis, complicated with cor pulmonale. However, this was previously clinically misdiagnosed as PTB.
