    (Antibiotics, 2021) Kizito, Mark; Lalitha, Rejani; Kajumbula, Henry; Ssenyonga, Ronald; Muyanja, David; Byakika-Kibwika, Pauline
    Excessive use of ceftriaxone contributes to the emergence and spread of antimicrobial resistance (AMR). In low and middle-income countries, antibiotics are overused but data on consumption are scarcely available. We aimed to determine the prevalence and factors influencing ceftriaxone prescription in a tertiary care private not-for-profit hospital in Uganda. Methods: A cross-sectional study was carried out from October 2019 through May 2020 at Mengo Hospital in Uganda. Patients admitted to the medical ward and who had been prescribed antibiotics were enrolled. Sociodemographic and clinical data were recorded in a structured questionnaire. Bivariate and adjusted logistic regression analyses were performed to determine factors associated with ceftriaxone prescription. Results: Study participants were mostly female (54.7%). The mean age was 56.2 years (SD: 21.42). The majority (187, 73.3%) presented with fever. Out of the 255 participants included in this study, 129 (50.6%) participants were prescribed ceftriaxone. Sixty-five (25.5%) and forty-one (16.0%) participants had a prescription of levofloxacin and metronidazole, respectively. Seven participants (2.7%) had a prescription of meropenem. Out of 129 ceftriaxone prescriptions, 31 (24.0%) were in combination with other antibiotics. Overall, broad-spectrum antibiotic prescriptions accounted for 216 (84.7%) of all prescriptions

    (Journal of Clinical Microbiology, 2020) Meyer, Amanda J.; Ochom, Emmanuel; Turimumahoro, Patricia; Byanyima, Patrick; Sanyu, Ingvar; Lalitha, Rejani; Kaswabuli, Sylvia; Andama, Alfred; Walter, Nicholas D.; Katamba, Achilles; Cattamanchi, Adithya; Worodria, William; Huang, Laurence; Yoon, Christina; Davis, Lucian
    The objective of this prospective cross-sectional study, conducted at a national referral hospital in Kampala, Uganda, was to determine diagnostic performance of serum C-reactive protein (CRP) as a triage test for tuberculosis (TB) among HIV-seronegative inpatients. We calculated the sensitivity, specificity, positive and negative likelihood ratios, and positive and negative predictive values to determine the diagnostic performance of a CRP enzyme-linked immunosorbent assay (ELISA) (Eurolyser) in comparison to that of a reference standard of Mycobacterium tuberculosis culture on two sputum samples. We constructed receiver operating curves and reported performance in reference to the manufacturer’s cutoff and also to a threshold chosen to achieve sensitivity of 90%, in accordance with the WHO’s targetproduct profile for a triage test. Among 119 HIV-seronegative inpatients, 46 (39%) had culture-positive pulmonary TB. In reference to M. tuberculosis culture, CRP had a sensitivity of 78% (95% confidence interval [CI], 64 to 89%) and a specificity of 52% (95% CI, 40 to 64%) at the manufacturer’s threshold of 10 mg/liter. At a threshold of 1.5 mg/liter, the sensitivity was 91% (95% CI, 79 to 98%) but the specificity was only 21% (95% CI, 12 to 32%). Performance did not differ when stratified by illness severity at either threshold. In conclusion, among HIV-seronegative inpatients, CRP testing performed substantially below targets for a TB triage test. Additional studies among HIV-seronegative individuals in clinics and community settings are needed to assess the utility of CRP for TB screening.

    Diagnosis of alcohol misuse and alcoholic liver disease among patients in the medical emergency admission service of a large urban hospital in Sub-Saharan Africa; a cross sectional study
    (Pan African Medical Journal, 2013) Kenneth Opio, Christopher; Seremba, Emmanuel; Ocama, Ponciano; Lalitha, Rejani; Kagimu, Magid; Martens Lee, William
    Uganda is among the top ten consumers of alcohol worldwide though there is little data on alcohol related liver disease. We describe alcohol use, alcohol misuse, and alcoholic liver disease among adults at the emergency admission service of a large urban hospital in Uganda. Methods: All adults who consented were prospectively evaluated for alcohol use by inquiry and alcohol misuse by the "Cutting down, Annoyance, Guilt and Eye-opener- CAGE" questionnaire. Alcohol related hepatocellular liver injury was assessed using aspartate aminotransferase, and alanine aminotransferase levels. A combination of CAGE score ≥2 and De Ritis ratio ≥2 defined alcoholic liver disease (ALD). Human Immunodeficiency Virus (HIV), and viral hepatitis B and C serologies were evaluated in all the patients. Descriptive and inferential statistics were generated to answer our research questions. Results: Three hundred and eighty individuals consented and participated in the study. Among these, 46.8% acknowledged use of alcohol while 21% and 10% met the study definition of alcoholic misuse and alcoholic liver disease respectively. Both alcohol misuse and alcoholic liver disease was significantly associated (p-value ≤ 0.05) with male gender, region of origin, number of life time sexual partners and serum albumin below 3.5 mg/dl after univariate and multivariate analysis. Conclusion: Alcohol misuse and alcoholic liver disease is frequent in this medical emergency unit. Our study suggests a link between alcohol misuse or alcoholic liver disease and male gender, region of origin, number of sexual partners, and serum albumin below 3.5mg/dl.

    Internal Medicine Clerkship Amidst COVID-19 Pandemic: A Cross-Sectional Study of the Clinical Learning Experience of Undergraduate Medical Students at Makerere University, Uganda
    (Advances in Medical Education and Practice, 2021) Bongomin, Felix; Olum, Ronald; Nakiyingi, Lydia; Lalitha, Rejani; Ssinabulya, Isaac; Sekaggya- Wiltshire, Christine; Ocama, Ponsiano; Byakika-Kibwika, Pauline
    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. Twentytwo 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.

    Sex and HIV Differences in Preserved Ratio Impaired Spirometry (PRISm) Among Ugandans Postpneumonia
    (Oxford University Press, 2024-03) Abelman, Rebecca A; Fitzpatrick, Jessica; Byanova, Katerina L; Zawedde, Josephine; Sanyu, Ingvar; Byanyima, Patrick; Musisi, Emmanuel; Hsieh, Jenny; Zhang, Michelle; Branchini, Jake; Sessolo, Abdul; Hunt, Peter W; Lalitha, Rejani; Davis, J Lucian; Crothers, Kristina; Worodria, William; Huang, Laurence
    Preserved ratio impaired spirometry (PRISm), defined as a normal ratio of forced expiratory volume in 1 second (FEV ) to forced vital capacity (≥0.70) with low FEV (<80% predicted), has been associated with increased mortality in the general population. Female sex has been associated with increased odds of PRISm in people without HIV. People with HIV (PWH) are at increased risk for lung function abnormalities, but whether HIV modifies the effect of sex on PRISm development is largely unknown. Adults with and without HIV underwent baseline followed by serial spirometry after completing therapy for pneumonia, predominantly tuberculosis (TB), in Kampala, Uganda. Using generalized estimating equations adjusted for age, body mass index, smoking, biomass fuel exposure, HIV, and TB status, we compared individuals with PRISm with those with normal spirometry. These models were stratified by HIV status. Of 339 baseline participants, 153 (45%) were women; 129 (38%) had HIV, of whom 53% were women. Overall, 105/339 participants (31%) had PRISm at baseline. HIV was associated with lower odds of PRISm (adjusted odds ratio [aOR], 0.38; 95% CI, 0.21-0.68; = .001). Female sex trended toward increased odds of PRISm among all participants (aOR, 1.65; 95% CI, 0.99-2.75; = .052). The association between female sex and PRISm tended to be stronger among PWH (aOR, 3.16; 95% CI, 1.14-8.76; = .03) than among those without HIV (aOR, 1.34; 95% CI, 0.73-2.45; = .34); this study was underpowered to detect an HIV-sex interaction of this magnitude ( = .30). Among Ugandan adults who recovered from pneumonia, female sex was associated with increased odds and HIV with decreased odds of PRISm, suggesting independent sex and HIV effects on PRISm pathogenesis.
