Self-medication with antibiotics during the COVID-19 pandemic: A cross-sectional study among adults in Tema, Ghana.

BACKGROUND: Antibiotic self-medication is one of the common causes of antibiotic resistance of bacterial organisms. The COVID-19 pandemic introduced a new paradigm shift and significantly influenced healthcare behaviors, including an increase in antibiotic self-medication, which contributes to antibiotic resistance. This study was aimed at determining the prevalence of antibiotic self-medication and the possible associated factors during the peak of the COVID-19 pandemic among adult residents of Tema in Ghana from April to July 2021. METHODS: Using a cross-sectional design, 400 adults were randomly selected and surveyed using a researcher-assisted questionnaire. Data were analyzed with IBM® SPSS® Statistics Version 22.0, considering associations significant at a 95% confidence interval (p < 0.05). RESULTS: Of the 400 respondents, (76%) 304 had practiced antibiotic self-medication within the previous 12 months during the COVID-19 pandemic. Significant factors associated with antibiotic self-medication included gender, age, marital status, education, occupation, and National Health Insurance Scheme subscription. Convenience and avoiding long hospital queues were primary non-medical reasons for antibiotic self-medication, while previous successful experience, easy access to antibiotics, treating symptoms, prophylaxis, and fear of hospital infection were the medical reasons for antibiotic self-medication. Commonly self-administered antibiotics were azithromycin (34%), amoxicillin/clavulanic acid (22%), and metronidazole (16%) for perceived respiratory tract and gastrointestinal tract infections. CONCLUSIONS: The high prevalence of antibiotic self-medication observed during the COVID-19 pandemic underscores the need for enhanced public education and stricter enforcement of regulations governing antibiotic sales. The non-medical and medical factors of convenience, avoiding long hospital queues, previous successful experience, easy access to antibiotics, treating symptoms, prophylaxis, and fear of hospital infection which motivated antibiotic self-medication practices require the implementation of antimicrobial stewardship interventions.

Molecular Epidemiology of SARS-CoV-2 within Accra Metropolis Postlockdown.

Introduction: Currently, sequencing has been the only tool for the identification of circulating severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) variants. However, it is known to be an expensive and laborious approach involving high technical expertise. Considering the reduced adherence to preventive measures postlockdown in Accra, this study presents an alternative method that leverages polymerase chain reaction (PCR) to identify circulating SARS-CoV-2 variants in the Accra Metropolis postlockdown. Methods: This prospective cross-sectional study was conducted between July and December 2022. Nasopharyngeal samples were collected from 268 consenting participants. Samples were subjected to nucleic acid extraction and followed by real-time polymerase chain reaction for the detection and quantification of SARS-CoV-2 RNA. SARS-CoV-2 positive samples were subsequently subjected to variant identification using rapid PCR. Findings. The prevalence of SARS-CoV-2 within the Accra Metropolis was 30.2%. The majority of the SARS-CoV-2 infection was diagnosed in females, participants aged 41-50 years, and symptomatic participants. Participants aged ≤10 years and females recorded the highest viral load while participants aged 41-50 years recorded the highest number of infections. The SARS-CoV-2 variants detected were Alpha (64.2%), Delta (22.2%), and Omicron (13.6%). Predictors of SARS-CoV-2 infection identified were chills, cough, headache, body weakness, sore throat, and dyspnoea in order of decreasing association with SARS-CoV-2 infection. There was a strong association between symptom status, gender, age, and SARS-CoV-2 infection. Conclusion: There was a high prevalence of SARS-CoV-2 within the Accra Metropolis postlockdown within the sampling period. The Alpha variant of SARS-CoV-2 is the predominant circulating variant, and persons presenting with symptoms are most likely to be diagnosed with COVID-19. Children aged ≤10 years serve as a reservoir for infection transmission.

Comparative evaluation of RT-PCR and antigen-based rapid diagnostic tests (Ag-RDTs) for SARS-CoV-2 detection: performance, variant specificity, and clinical implications.

The COVID-19 pandemic has highlighted the critical need for accurate and efficient diagnostic tools for detecting severe acute respiratory coronavirus 2 (SARS-CoV-2) infections. This study presents a comparison of two diagnostic tests: RT-PCR and antigen detection rapid diagnostic tests (Ag-RDTs). This study focused on their performance, variant specificity, and their clinical implications. A simultaneous testing of 268 samples was carried out for SARS-CoV-2 using RT-PCR and Ag-RDTs [flourescence immunoassay (FIA) and lateral flow immunoassay (LFIA)]. Viral load was quantified, and variant identification was performed using a PCR-based assay. The prevalence was found to be 30.2% using reverse transcription PCR (RT-PCR), 26.5% using FIA, and 25% using LFIA. When comparing the FIA and LFIA, the overall diagnostic performance was found to be 80.25% vs 76.54%, 96.79% vs 97.33%, 91.55% vs 90.51%, and 91.88% vs 92.56% for sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV), respectively. Both Ag-RDTs showed a strong agreement with RT-PCR (κ = 0.78-0.80). The overall accuracies of the FIA and LFIA were 92.41% and 92.13%, respectively. The FIA showed higher sensitivity (73.68%) and PPV (92.08%) than the LFIA (65.79% and 90.56%, respectively) in asymptomatic patients. At low Ct values (<25), both Ag-RDTs had 100% sensitivity, but the sensitivity reduced to 31.82% for FIA and 27.27% for LFIA at Ct values > 30. The diagnostic sensitivity of FIA compared to LFIA for detecting the Alpha variant was 78.85% vs. 69.23% and 72.22% vs. 83.33% for the Delta variant. Both Ag-RDTs had 100% sensitivity for detecting Omicron. Both Ag-RDTs performed well in patients with high viral loads and Omicron variant infections compared to those infected with Alpha and Delta variants. This study confirms the comparable performance of RT-PCR and Ag-RDTs, specifically FIA and LFIA, for SARS-CoV-2 detection. The FIA showed higher sensitivity and PPV in asymptomatic cases, while both Ag-RDTs exhibited strong agreement with RT-PCR results. Notably, Ag-RDTs, particularly FIA, proved effective in detecting the Omicron variant and cases with high viral loads, highlighting their potential clinical utility in managing the COVID-19 pandemic.IMPORTANCEThis study is of utmost importance in providing effective responses to manage the COVID-19 pandemic. It rigorously compares the diagnostic accuracy, variant specificity, and practical considerations of reverse transcription PCR (RT-PCR) and antigen detection rapid diagnostic tests (Ag-RDTs) for severe acute respiratory coronavirus 2 (SARS-CoV-2), answering critical questions. The results of this study will help healthcare professionals choose the appropriate testing methods, allocate resources effectively, and enhance public health strategies. Given the evolution of the virus, understanding the performance of these diagnostic tools is crucial to adapting to emerging variants. Additionally, the study provides insights into logistical challenges and accessibility issues, which will contribute to refining testing workflows, particularly in resource-limited settings. Ultimately, the study's impact extends to global healthcare, providing valuable information for policymakers, clinicians, and public health officials as they work together for mitigating the impact of the pandemic.

Seroprevalence and effect of HBV and HCV co-infections on the immuno-virologic responses of adult HIV-infected persons on anti-retroviral therapy.

Chronic hepatitis negatively affects persons living with HIV. While varying in their transmission efficiency, HIV, HBV, and HCV have shared routes of transmission. Available data suggest widely variable rates of HBV and HCV infections in HIV-infected populations across sub-Saharan Africa. With prolonged survival rates due to increased accessibility to antiretroviral drugs, HBV and HCV have the potential to complicate the prognosis of HIV co-infected patients by contributing significantly to continued morbidity and mortality. The study sought to determine the seroprevalence of HIV/HBV and HIV/HCV co-infections among HIV patients on antiretroviral therapy and to evaluate the effect of HIV/HBV and HIV/HCV co-infections on the immunologic and virologic responses of patients. A cross-sectional study in which samples were taken from 500 people living with HIV and attending ART clinic at the Fevers unit of the Korle Bu Teaching Hospital and tested for Hepatitis B Surface Antigen (HBsAg) and Hepatitis C virus antibody (HCV). CD4 cell counts and HIV-1 RNA levels were estimated as well. Data generated were analysed using IBM SPSS version 22. The seroprevalence of HIV/HBV and HIV/HCV co-infections among people living with HIV was 8.4% and 0.2% respectively. HIV/HBV coinfection included 15/42 (35.7%) males and 27/42 (64.3%) females out of which the majority (97.6%) were in the 21-60 years old bracket. HIV/HBV and HIV/HCV co-infections have varied effects on the immunological and virological response of HIV patients on ART. The mean CD cell count was 361.0 ± 284.0 in HIV/HBV co-infected patients and 473.8 ± 326.7 in HIV mono-infected patients. The mean HIV-1 RNA level was not significantly different (X2 [df] = .057 [1]; P = .811) among HIV/HBV co-infected patients (Log102.9±2.0 copies/mL), compared to that of HIV mono-infected patients (Log102.8±2.1 copies/mL) although HIV mono-infected patients had lower viral load levels. One-third (14/42) of HIV/HBV co-infected patients had virologic failure and the only HIV/HCV co-infected patient showed viral suppression. 336/500 (67.2%) patients had HIV-1 viral suppression (females [66.1%]; males [33.9%]) while 164/500 (32.8%) had virologic failure (females [67.7%]; males [32.3%]). The mean CD4 count of patients with viral suppression and patients with virologic failure was 541.2 cells/µL (95% CI 508.5-573.8) and 309.9 cell/µL (95% CI 261.9-357.9) respectively.The study concludes that, HIV/HBV and HIV/HCV coinfections do not significantly affect the immunologic and virologic responses of patients who have initiated highly active antiretroviral therapy, and treatment outcomes were better in females than in males. There was no HBV/HCV co-infection among patients.
