    Pneumonia is the leading cause of death in children, however, the microbial aetiology of pneumonia is not well elucidated in low- and middle-income countries. Our study was aimed at determining the microbial aetiologies of childhood pneumonia and associated risk factors in HIV and non-HIV infected children. We conducted a case-control study that enrolled chil dren with pneumonia as cases and non-pneumonia as controls from July 2017 to May 2020. Induced sputum and blood samples were investigated for microbial organisms using stan dard microbiological techniques. DNA/RNA was extracted from sputum samples and tested for viral and bacterial agents. Four hundred and four (404) subjects consisting of 231 (57.2%) cases and 173 (42.8%) controls were enrolled. We identified a significant (p =0.011) proportion of viruses in cases (125; 54.1%, 95%CI: 47.4–60.7) than controls (71;33.6%, 95%CI: 33.6–48.8) and these were mostly contributed to by Respiratory Syncytial Virus. Staphylococcus aureus (16; 4.0%), Klebsiella spp. (15, 3.7%) and Streptococcus pneumoniae (8, 2.0%) were the main bacterial agents identified in sputum or induced spu tum samples. HIV infected children with viral-bacterial co-detection were found to have verysevere pneumonia compared to those with only viral or bacterial infection. Indoor cooking (OR = 2.36; 95%CI:1.41–3.96) was found to be associated with pneumonia risk in patients. This study demonstrates the importance of various microbial pathogens, particularly RSV, in contributing to pneumonia in HIV and non-HIV paediatric populations. There is a need to accelerate clinical trials of RSV vaccines in African populations to support improvement of patient care

    Prevalence and risk factors of virological failure among children on antiretroviral therapy
    (BMG Glob Health, 2017) Owusu, Michael; Mensah, Michael; Enimil, Anthony; Mutocheluh, MOhammed; 0000-0001-5066-150X; 0000-0001-6521-3400
    An unprecedented global effort at scaling up universal access to antiretroviral therapy has decreased the progression of HIV. However, due to challenges with supplies and adherence to intermittent antiretroviral therapy (ART) for mothers, infants continue to be infected, some with resistant viruses. Exposure to these resistant strains leads to non responsiveness to therapy resulting in virological failure. Children are more vulnerable to HIV drug resistance because of their life long treatment, the possible selection of resistant strains as a result of prophylaxis for mothers with HIV enrolled in PMTCT. The objective of the study was to determine the prevalence and risk factors of virological resistance among HIV-1-positive children on antiretroviral therapy.
