    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.

    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

    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.

    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.

    Aspergillus-specific IgM/IgG antibody serostatus of patients hospitalized with moderate-critical COVID-19 in Uganda
    (African Health Sciences, 2022-09-03) Bongomin, Felix; Kwizera, Richard; Mande, Emmanuel; Aloyo, Sharley Melissa; Achan, Beatrice; Namusobya, Martha; Sereke, Senai Goitom; Batte, Charles; Kiguli, Sarah; Baruch Baluku, Joseph; Joloba, Moses L; Kirenga, Bruce J
    Invasive pulmonary aspergillosis is known to complicate the coronavirus diseases-2019 (COVID-19), especially those with crit ical illness. We investigated the baseline anti-Aspergillus antibody serostatus of patients with moderate-critical COVID-19 hos pitalized at 3 COVID-19 Treatment Units in Uganda. All 46 tested patients, mean age 30, and 11% with underlying respiratory disease had a negative serum anti-Aspergillus IgM/IgG antibody immunochromatographic test on day 3 (mean) of symptom onset (range 1-26), but follow up specimens to assess seroconversion were not available.

    Isolated renal and urinary tract aspergillosis: a systematic review
    (Sage Publications, 2023-11-16) Bongomin, Felix; Ekeng, Bassey E.; Mushi, Martha F.; Kibone, Winnie; Olum, Ronald; Meya, David B.; Hamer, Davidson H.; Denning, David W.; Morgan, Bethan
    Abstract Background: Aspergillosis localized to the kidneys and the urinary tract is uncommon. We conducted a comprehensive systematic review to evaluate risk factors and clinical outcomes of patients with isolated renal and genito-urinary tract aspergillosis. Methods: We systematically searched Medline, CINAHL, Embase, African Journal Online, Google Scholar, and the Cochrane Library, covering the period from inception to August2023 using the key terms ‘renal’ OR ‘kidney*’ OR ‘prostate’ OR ‘urinary bladder’ OR ‘urinary tract*AND ‘aspergillosis’ OR ‘aspergillus’ OR ‘aspergilloma’ OR ‘mycetoma’. We included single case reports or case series. Review articles, guidelines, meta-analyses, animal studies,protocols, and cases of genitourinary and /or renal aspergillosis occurring as a part of disseminated disease were excluded. Results: We identified 91 renal and urinary aspergillosis cases extracted from 76 publications spanning 1925–2023. Among the participants, 79 (86.8%) were male, with a median age of 46years. Predominantly, presentations consisted of isolated renal infections (74 instances,81.3%), followed by prostate (5 cases, 5.5%), and bladder (7 cases, 7.7%) involvement. Aspergillus fumigatus (42.9%), Aspergillus flavus (9.9%), and Aspergillus niger/glaucus (1.1% each) were isolated. Underlying risk factors included diabetes mellitus (29.7%), HIV (12.1%), haematological malignancies (11%), and liver cirrhosis (8.8%), while common symptoms encompassed flank pain (36.3%), fever (33%), and lower urinary tract symptoms (20.9%). An autopsy was conducted in 8.8% of cases. Diagnostic work-up involved histopathology (70.5%), renal CT scans and urine microscopy and culture (52.6% each), and abdominal ultrasound (17.9%). Treatments included amphotericin B (34 cases, 37.4%) and azole-based regimens (29 cases, 31.9%). Nephrectomy was performed in 16 of 78 renal cases (20.5%). All-cause mortality was 24.4% (19 cases). No significant mortality rate difference was observed among antifungal regimens (p=0.739) or nephrectomy status (p=0.8). Conclusion: Renal and urinary aspergillosis is an important cause of morbidity and mortality, particularly in immunocompromised and people with diabetes mellitus. While varied treatment strategies were observed, mortality rates showed no significant differences based on treatments or nephrectomy status. Further research is needed to refine diagnostics, optimize treatments, and enhance awareness among clinicians for early detection and management.

    "I thought I was going to die": Experiences of COVID-19 patients managed at home in Uganda
    (PLOS ONE, 2023-12-12) Nakireka, Susan; Mukunya, David; Tumuhaise, Crescent; Olum, Ronald; Namulema, Edith; Napyo, Agnes; Serwanja, Quraish; Ingabire, Prossie Merab; Muyinda, Asad; Bongomin, Felix; Musaba, Milton; Mutaki, Vivian; Nantale, Ritah; Akunguru, Phillip; Ainembabazi, Rozen; Nomujuni, Derrick; Olwit, William; Nakawunde, Aisha; Nyiramugisha, Specioza; Mwa Aol, Pamela; Rujumba, Joseph; Munabi, Ian; Kiguli, Sarah
    Background In Uganda, approximately 170,000 confirmed COVID-19 cases and 3,630 deaths have been reported as of January 2023. At the start of the second COVID-19 wave, the Ugandan health system was overwhelmed with a sudden increase in the number of COVID-19 patients who needed care, and the Ministry of Health resorted to home-based isolation and care for patients with mild to moderate disease. Before its rollout, the COVID-19 homebased care strategy had neither been piloted nor tested in Uganda. Objective To explore the experiences of COVID-19 patients managed at home in Uganda. Methods This was a qualitative study that was conducted to explore the lived experiences of COVID19 patients managed at home. The study was carried out among patients who presented to three hospitals that were designated for treating COVID-19 patients in Uganda. COVID-19 patients diagnosed at these hospitals and managed at home were followed up and contacted for in-depth telephone interviews. The data were analysed using thematic content analysis with the aid of NVIVO 12.0.0 (QRS International, Cambridge, MA). Results Participants experienced feelings of fear and anxiety: fear of death, fear of losing jobs, fear of infecting loved ones and fear of adverse events such as loss of libido. Participants also reported feelings of loneliness, hopelessness and depression on top of the debilitating and sometimes worsening symptoms. In addition to conventional medicines, participants took various kinds of home remedies and herbal concoctions to alleviate their symptoms. Furthermore, COVID-19 care resulted in a high economic burden, which persisted after the COVID-19 illness. Stigma was a major theme reported by participants. Participants recommended that COVID-19 care should include counselling before testing and during and after the illness to combat the fear and stigma associated with the diagnosis. Another recommendation was that health workers should carry out home visits to patients undergoing homebased care and that COVID-19 treatment should be free of charge. Conclusion COVID-19 home-based care was associated with fear, anxiety, loneliness, depression, economic loss and stigma. Policymakers should consider various home-based follow-up strategies and strengthen counselling of COVID-19 patients at all stages of care.
