Item 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, BethanAbstract 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.Item "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, SarahBackground 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.Item Prevalence of chronic pulmonary aspergillosis along the continuum of pulmonary tuberculosis care: A protocol for a living systematic review and meta-analysis(PLOS ONE, 2023-12-15) Bongomin, Felix; Olum, Ronald; Kibone, Winnie; Namusobya, Martha; Rhijn, Norman van; Denning, David W.Introduction Chronic pulmonary aspergillosis (CPA) is a debilitating disease estimated to affect over 3million people worldwide. Pulmonary tuberculosis (PTB) is the most significant risk factor for CPA. However, the true burden of CPA at the time of PTB diagnosis, during, and after PTB treatment remains unknown. In this paper, we present a protocol for a living systematic review aimed at estimating the current burden of CPA along the continuum of PTB care. Materials and methods We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) guidelines to formulate this protocol, which is registered with the International Prospective Register of Systematic Reviews (PROSPERO: CRD42023453900). We will identify primary literature through various electronic databases, including CINAHL, Ovid MEDLINE, MEDLINE (PubMed), EMBASE, Google Scholar, Cochrane Database of Systematic Reviews, and African Journal Online. The search will encompass articles from inception to December 31st, 2023, using medical subject heading search terms "pulmonary tuberculosis" AND "chronic pulmonary aspergillosis". Two reviewers will independently assess titles, abstracts, and full texts for eligibility using the Covidence web-based software.The eligible studies will comprise original observational research that reports on the prevalence of CPA diagnosed in individuals with PTB, based on established criteria, without language or geographic restriction. We intend to exclude single case reports and case series with fewer than 10 participants, as well as review articles, guidelines, and letters to the editors. Cochrane Risk of Bias Tools (ROB2 and ROBINS-I) will used to assess study quality and risk of bias and the quality of the evidence will be rated using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) tool. Our data syntheses will encompass meta-analysis and meta-regression, conducted using STATA version 18 and R- Studio version 4.0.2. This systematic review will be updated every 3–5years as more data emerges. Conclusions The findings of this proposed systematic review will summarize the available evidence on the occurrence of CPA, at the time of PTB diagnosis, during and after PTB treatment. The study results have the potential to guide healthcare policies regarding screening for CPA,enhance clinical decision-making, and catalyse further research into understanding the interplay between PTB and CPA. By shedding light on the current burden of CPA along the continuum of PTB care, we aspire to contribute to the betterment of patient care, disease management, and global health outcomes.Item Invasive Fungal Diseases in Africa:(MDPI, 2022-11-22) Bongomin, Felix; Ekeng, Bassey E.; Kibone, Winnie; Nsenga, Lauryn; Olum, Ronald; Itam-Eyo, Asa; Ngouanom Kuate, Marius Paulin; Pebolo, Francis Pebalo; Davies, Adeyinka A; Manga, Musa; Ocansey, Bright; Kwizera, Richard; Baluku, Joseph BaruchInvasive fungal diseases (IFDs) are of huge concern in resource-limited settings, particularly in Africa, due to the unavailability of diagnostic armamentarium for IFDs, thus making definitive diagnosis challenging. IFDs have non-specific systemic manifestations overlapping with more frequent illnesses, such as tuberculosis, HIV, and HIV-related opportunistic infections and malignancies. Consequently, IFDs are often undiagnosed or misdiagnosed. We critically reviewed the available literature on IFDs in Africa to provide a better understanding of their epidemiology, disease burden to guide future research and interventions. Cryptococcosis is the most encountered IFD in Africa, accounting for most of the HIV-related deaths in sub-Saharan Africa. Invasive aspergillosis, though somewhat underdiagnosed and/or misdiagnosed as tuberculosis, is increasingly being reported with a similar predilection towards people living with HIV. More cases of histoplasmosis are also being reported with recent epidemiological studies, particularly from Western Africa, showing high prevalence rates amongst presumptive tuberculosis patients and patients living with HIV. The burden of pneumocystis pneumonia has reduced significantly probably due to increased uptake of anti-retroviral therapy among people living with HIV both in Africa, and globally. Mucormycosis, talaromycosis, emergomycosis, blastomycosis, and coccidiomycosis have also been reported but with very few studies from the literature. The emergence of resistance to most of the available antifungal drugs in Africa is yet of huge concern as reported in other regions. IFDs in Africa is much more common than it appears and contributes significantly to morbidity and mortality. Huge investment is needed to drive awareness and fungi related research especially in diagnostics and antifungal therapy.Item Diagnostic Accuracy of Clinical Diagnostic Scoring Systems for Childhood Tuberculosis: A Systematic Review and Meta-analysis(Oxford University Press, 2023-12-11) Kakinda, Michael; Olum, Ronald; Baluku, Joseph Baruch; Bongomin, FelixBackground. Diagnosis of childhood tuberculosis (TB) poses several challenges. Therefore, point-based scoring systems and diagnostic algorithms have been developed to improve the diagnostic yields in this population. However, there are no updated systematic reviews of the existing childhood TB scoring systems and algorithms. Hence, we systematically reviewed the diagnostic accuracy of the childhood TB diagnostic scoring systems and algorithms. Methods. We systematically searched PubMed, CINAHL, Embase, Scopus, and Google Scholar databases for relevant articles published until 30 March 2023. QUADAS-2 was used to assess their study quality. Diagnostic accuracy measures (ie, sensitivity, specificity, diagnostic odds ratio, positive and negative likelihood ratios) were pooled using a random-effects model. Results. We included 15 eligible studies, with a total of 7327 study participants aged <15 years, with 10 evaluations of childhood TB diagnostic scoring systems and algorithms. Among these algorithms and scoring systems, only 3 were evaluated more than once. These were the Keith Edwards scoring system with 5 studies (sensitivity, 81.9%; specificity, 81.2%), Kenneth Jones criteria with 3 studies (sensitivity, 80.1%; specificity, 45.7%), and the Ministry of Health–Brazil algorithm with 3 studies (sensitivity, 79.9%; specificity, 73.2%). Conclusions. We recommend using the Keith Edwards scoring system because of its high sensitivity and specificity. Further research is necessary to assess the effectiveness of scoring systems and algorithms in identifying TB in children with HIV and malnutrition.Item Burden and associated phenotypic characteristics of tuberculosis infection in adult Africans with diabetes: a systematic review(Springer Nature, 2023) Kibirige, Davis; Biraro, IreneAndia; Kyazze, Andrew Peter; Olum, Ronald; Bongomin, Felix; Nakavuma, Rose Mwanje; Ssekamatte, Phillip; Emoru, Reagan; Nalubega, Goretti; Chamba, Nyasatu; Kilonzo, Kajiru; Laizer, Sweetness Naftal; Mrema, Lucy Elauteri; Olomi, Willyhelmina; Minja, LilianTina; Ntinginya, Nyanda Elias; Sabi, Issa; Hill, Philip C.; Brake, Lindsey te; Crevel, Reinout van; Sharples, Katrina; Critchley, JuliaDiabetes mellitus (DM) increases the risk of developing tuberculosis infection (TBI). However, the evidence on the burden and phenotypic characteristics of TBI in African patients with DM is limited. This study aimed to determine the prevalence and characterisation of TBI in native African patients living with DM. We searched PubMed, EMBASE, and African Journals Online for original studies reporting information on the prevalence and characteristics of TBI in adult Africans with DM. A forest plot was used to describe the pooled prevalence estimate of TBI and the corresponding 95% confdence intervals (CI). Six studies conducted in four African countries involving 721 participants with DM were included in this systematic review. The pooled prevalence estimate of TBI was 40% (95% CI 20–60%, I 2 = 98.52%, p< 0.001). Age ≥ 40 years and glycated haemoglobin levels independently predicted TBI positivity in patients with DM in three studies. Africans with DM have a high prevalence of TBI, especially those who are older or with poorly controlled diabetes. This justifes the need for studies to explore how to screen and manage TBI to avert the progression to active TB diseaseItem Prevalence of cardiovascular risk factors in active tuberculosis inAfrica: a systematic review and meta‑analysis(Scientifc Reports, 2022-09-19) Baruch Baluku, Joseph; Olum, Ronald; Bagasha, Peace; Okello, Emmy; Bongomin, FelixPeople with tuberculosis (TB) are at risk of major adverse cardiovascular events. We estimated the prevalence of cardiovascular risk (CVR) factors among people with active TB in Africa. This was a systematic review and meta-analysis of studies from Africa. We searched EMBASE, MEDLINE through PubMed, Web of Science, the Cochrane Central Register of Controlled Trials, mRCTs, Clinical trials.gov, and International Clinical Trials Registry Platform from inception to 31st December 2021. Among 110 eligible studies, 79 (238,316 participants) were included in the meta-analysis for smoking, 67 (52,793 participants) for current alcohol use, 30 (31,450 participants) for hazardous alcohol use, 51 (37,879 participants) for diabetes mellitus (DM), 19 (18,211 participants) for hypertension and 18 (13,910 participants) for obesity. The pooled prevalence was 26.0% (95% confidence interval 22.0–29.0) for smoking, 30.0% (25.0–35.0) for any current alcohol use, 21.0% (17.0–26.0) for hazardous alcohol use, 14.0% (9.0–18.0) for hypertension, 7.0% (6.0–9.0) for DM, and 4.0% (2.0–5.0) for obesity. Cost effective strategies are needed to screen for CVR factors among people with active TB in Africa.Item Internal Medicine Clerkship Amidst COVID-19 Pandemic: A Cross-Sectional Study of the Clinical Learning Experience of Undergraduate Medical Students at Makerere University, Uganda(Dove Press, 2021) Bongomin, Felix; Olum, Ronald; Nakiyingi, Lydia; Lalitha, Rejani; Ssinabulya, Isaac; Sekaggya Wiltshire, Christine; Ocama, Ponsiano; Byakika-Kibwika, PaulineBackground: The coronavirus-2019 (COVID-19) pandemic continues to impose a significant impact on medical education. We aimed to describe the clinical learning experience of undergraduate medical students undertaking internal medicine clerkship during the COVID-19 pandemic at Makerere University, Uganda. Methods: A descriptive, cross-sectional study among medical students in clinical years of study pursuing the Bachelor of Medicine and Bachelor of Surgery undergraduate degree program was conducted in November 2020. Only 3rd (junior clerks) and 5th (senior clerks) year medical students whose internal medicine clerkships were interrupted by the COVID-19 pandemic were studied. Results: Data of 188 (95%) eligible clinical year students; junior (101, 54.0%) and senior (86, 46.0%) were analysed. Median age was 24 (range: 22–42) years. Majority (70.1%) were male and Ugandan nationals (94.1%). Sixty-four (30.3%) students reported inadequate personal protective equipment, 152 (81.7%) felt at risk of contracting COVID-19, and 127 (67.9%) said it was difficult to observe COVID-19 standard operating procedures. Twenty two students (11.9%) were discouraged from pursuing a career in internal medicine. Overall, most students reported good or excellent clinical experience pre-COVID-19 era compared to during the COVID-19 era (4.0 vs 3.5, p<0.0001). Senior clerks significantly believed that the time allocated for the rotation was adequate (p<0.0001) and they were able to complete their study objectives (p<0.001), compared to the junior clerks. Senior clerks believed that learning was difficult when combined with junior clerks (p=0.013). About half of the students (51.4%, n=95) reported clinical teaching should remain as it was in the pre COVID-19 era. Conclusion: The COVID-19 pandemic has had a significantly negative effect on the clinical learning experience of the students. There is need to review the current teaching and learning methods to suit teaching and learning during pandemics of highly infectious diseases to ensure safe and effective learning experience.Item Anemia in Ugandan pregnant women: a cross-sectional, systematic review and meta-analysis study(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, IreneBackground: 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.Item Burden and associated phenotypic characteristics of tuberculosis infection in adult Africans with diabetes: a systematic review(Scientific Reports, 2023-11-11) Kibirige, Davis; Andia‑Biraro, Irene; Kyazze, Andrew Peter; Olum, Ronald; Bongomin, Felix; Mwanje Nakavuma, Rose; Ssekamatte, Phillip; Emoru, Reagan; Nalubega, Goretti; Chamba, Nyasatu; Kilonzo, Kajiru; Naftal Laizer, Sweetness; Elauteri Mrema, Lucy; Olomi, Willyhelmina; Minja, Lilian Tina; Ntinginya, Nyanda Elias; Sabi, Issa; Hill, Philip C.; te Brake, Lindsey; van Crevel, Reinout; Sharples, Katrina; Critchley, JuliaDiabetes mellitus (DM) increases the risk of developing tuberculosis infection (TBI).
