RESUMEN

The nucleos(t)ide analogs require phosphorylation to the pharmacologically active anabolites in cells. We investigated the hypothesis that single-nucleotide polymorphisms (SNPs) in genes that encode transporters and phosphodiesterase (PDE) enzymes involved in tenofovir (TFV), disoproxil fumarate (TDF), and lamivudine (3TC) disposition will be associated with concentrations of their phosphate anabolites and virologic response. Individuals with human immunodeficiency virus (HIV) and hepatitis B virus (HBV) coinfection receiving TDF/3TC-containing antiretroviral therapy were enrolled. Steady-state TFV diphosphate (TFV-DP) and 3TC triphosphate (3TC-TP) concentrations in peripheral blood mononuclear cells (PBMCs) and dried blood spot samples were quantified. The relationship between genetic variants and TFV-DP and 3TC-TP concentrations as well as with virologic response were examined using multivariable linear regression. Of the 136 participants (median age 43 years; 63% females), 6.6% had HBV non-suppression, and 7.4% had HIV non-suppression. The multidrug resistance protein 2 (encoded by ABCC2 rs2273697) SNP was associated with 3TC-TP concentrations in PBMCs. The human organic anion transporter-1 (encoded by SLC28A2) rs11854484 SNP was associated with HIV non-suppression, and when evaluated together with SNPs with marginal associations (ABCC2 rs717620 and PDE1C rs30561), participants with two or three variants compared to those with none of these variants had an adjusted odds ratio of 48.3 (confidence interval, 4.3-547.8) for HIV non-suppression. None of the SNPs were associated with HBV non-suppression. Our study identified ABCC2 SNP to be associated with 3TC-TP concentrations in PBMCs. Also, a combination of genetic variants of drug transporters and PDE was associated with HIV non-suppression.

RESUMEN

BACKGROUND: The lateral flow urine lipoarabinomannan assay, Determine TB LAM (Determine LAM), offers the potential for timely tuberculosis (TB) treatment among people with human immunodeficiency virus (PWH). METHODS: In this cluster-randomized trial, Determine LAM was made available with staff training with performance feedback at 3 hospitals in Ghana. Newly admitted PWH with a positive World Health Organization four-symptom screening for TB, severe illness, or advanced HIV were enrolled. The primary outcome was days from enrollment to TB treatment initiation. We also reported the proportion of patients with a TB diagnosis, initiating TB treatment, all-cause mortality, and Determine LAM uptake at 8 weeks. RESULTS: We enrolled 422 patients including 174 (41.2%) in the intervention group. The median CD4 count was 87 (interquartile range [IQR], 25-205) cells/µL, and 32.7% were on antiretroviral therapy. More patients were diagnosed with TB in the intervention compared with the control group: 59 (34.1%) versus 46 (18.7%) (P < .001). Time to TB treatment remained constant, but patients were more likely to initiate TB treatment (adjusted hazard ratio, 2.19 [95% CI, 1.60-3.00]) during the intervention. Of patients with a Determine LAM test available, 41 (25.3%) tested positive. Of those, 19 (46.3%) initiated TB treatment. Overall, 118 patients had died (28.2%) at 8 weeks of follow-up. CONCLUSIONS: The Determine LAM intervention in real-world practice increased TB diagnosis and the probability of TB treatment but did not reduce time to treatment initiation. Despite high uptake, only half of the LAM-positive patients initiated TB treatment.

RESUMEN

BACKGROUND: Catheter-Related Bloodstream Infections (CRBSIs) are notable complications among patients receiving maintenance haemodialysis. However, data on the prevalence of CRBSIs is lacking. This study was conducted to determine the prevalence and factors associated with CRBSIs among patients receiving haemodialysis in the renal unit of the largest tertiary hospital in Ghana. METHODS: A hospital-based cross-sectional study was conducted on patients receiving maintenance haemodialysis via central venous catheters (CVC) between September 2021 and April 2022. Multivariate analysis using logistic regression was used to determine the risk factors that were predictive of CRBSI. Analysis was performed using SPSS version 23 and a p-value<0.05 was statistically significant. RESULTS: The prevalence of CRBSI was 34.2% (52/152). Of these, more than half of them (53.9%(28/52)) had Possible CRBSI while 11.5% (6/52) had Definite CRBSI. Among the positive cultures, 62% (21/34) were from catheter sites whilst the rest were from peripheral blood. Gram-negative cultures made up 53% (18/34) of positive cultures with the rest being Gram positive cultures. Acinetobacter baumannii (33.3% (6/18)) was the commonest organism isolated among Gram-negative cultures whilst Coagulase negative Staphylococci (43.7% (7/16)) was the commonest organism isolated among Gram-positve cultures. Gram-negative bacilli were more predominant in this study making up 52.9% of the total bacteria cultured. Sex, duration of maintenance dialysis, underlying cause of End-stage kidney disease, mean corpuscular haemoglobin (MCH), neutrophil count and lymphocyte count were significantly predictive of CRBSI status (p<0.05). CONCLUSION: There was a high prevalence of CRBSI among patients undergoing haemodialysis. The commonest causative agent was Coagulase negative Staphylococci, however there was a predominance of Gram-negative bacilli as compared to Gram positive cocci. There is a need to set up infection surveillance unit in the renal unit to track CRBSI and put in place measures to reduce these CRBSI.

RESUMEN

BACKGROUND: Living with HIV/AIDS is remarkably stressful and has an adverse effect on one's physical and mental health. In Sub-Saharan Africa, the introduction of highly active anti-retroviral therapy has led to an increased number of children with perinatal acquired HIV who are living into adolescence and adulthood. Developing strategies to cope with HIV becomes imperative, especially among these adolescents. The study determined the factors that influence coping strategies among adolescents living with HIV. METHODS: An analytic cross-sectional design was used. A total of 154 adolescents aged 10-19 years living with HIV were systematically sampled at the Fevers Unit of Korle Bu Teaching Hospital from June to December, 2021. The adolescent version of the KidCope tool was used to assess the choice of coping strategies. Stata 16 was used to determine associations between independent variables and the coping strategies identified. Only variables that were significant at p = 0.1 or less in the crude model were used to run the adjusted regression model. The level of significance was set at p = 0.05 with a 95% confidence interval. RESULTS: The mean age of participants was 19.2 ± 0.45 years with 51.9% (80/154) of participants being males. A majority, 57.1% of the participants employed positive coping strategies with 87.0% (135/154) using cognitive restructuring strategy. In an adjusted linear regression model, participants coping strategies were significantly associated with their educational level (p = 0.04) and presence of both parents as caregivers (p = 0.02). CONCLUSION: Participants largely adopted positive coping strategies in managing the disease. Factors that influenced the choice of coping strategies were higher levels of education and the presence of both parents as caregivers. The importance of a good social support structure and pursuing further education needs to be emphasized in counselling adolescents living with HIV as it promotes the choice of positive coping strategies.

RESUMEN

With the introduction of antiretroviral therapy (ART), many HIV-infected children are growing into adolescence and adulthood. A facility-based cross-sectional study was conducted at the Fevers Unit of one of the teaching hospitals in Ghana. The Morisky Medication Adherence Scale (MMAS-8) and pill count were used to assess adherence, while measured viral load levels of participants were used to assess viral suppression. The rate of viral suppression (<400 copies/ml) was 68.2%. Participants with high MMAS-8 scores were 8.4 times more likely to be virally suppressed compared to those with low MMAS-8 scores (OR = 8.4, p = 0.003, 95% CI: 2.11-33.48). The commonest reason for missing doses of their antiretroviral drugs (ARVs) was forgetfulness. Efforts must be made by all stakeholders involved in HIV care to engage adolescents and young adults living with HIV (AYALHIV) on personal and/or group levels to help identify and improve particular ART adherence issues so as to increase viral suppression rates.

RESUMEN

BACKGROUND: Diabetes often occurs together with tuberculosis (TB) and both may affect each other negatively. Diabetes may be associated with neurocognitive dysfunctioning in affected patients and may negatively impact treatment adherence and outcomes. This study compared the neurocognitive status between newly diagnosed smear positive tuberculosis patients with dysglycaemia and those with normoglycaemia. METHODS: The current study was a cross-sectional study involving one hundred and forty-six (146) newly diagnosed smear positive TB patients. Oral glucose tolerance test (OGTT) was performed and the results were categorized as either normoglycaemia, impaired glucose tolerance (IGT), impaired fasting glucose (IFG) or diabetes. Neurocognitive functioning among study participants was assessed at the time of TB diagnosis using Cognitive Failure Questionnaire (CFQ), Montreal Cognitive Assessment tool (MoCA), California Verbal Learning Test (CVLT), Brief Symptom Inventory (BSI) and the Spitzer Quality of Life Index (QLI). RESULTS: The mean age of the participants (n = 146) was 38.7 years with 78.8% being males and 21.2% females. Using the fasting blood glucose test, the prevalence of impaired fasting glucose and diabetes were 5.5 and 3.4% respectively, both representing a total of 13 out of the 146 participants; whilst the prevalence of impaired glucose tolerance and diabetes using 2-h post-glucose values were 28.8 and 11.6% respectively, both representing a total of 59 out of the 146 participants. There were no significant differences in the mean scores on the neurocognitive measures between the dysglaycaemia and normoglycamic groups using fasting plasma glucose (FPG). However, there were significant differences in the mean scores between the dysglycaemia and normal groups using 2-h postprandial (2HPP) glucose values on Phobic Anxiety (Normal, Mean = 0.38 ± 0.603; dysglycaemia, Mean = 0.23 ± 0.356; p = 0.045), and Montreal Cognitive Assessment (MoCA) scores (17.26 ± 5.981 vs. 15.04 ± 5.834, p = 0.037). CONCLUSION: Newly diagnosed smear positive patients with dysglycaemia were associated with significantly lower mean cognitive scores and scores on phobic anxiety than those with normoglyacaemia. The latter finding must be further explored.

RESUMEN

Peripheral neuropathy (PN) is the most frequent neurological complication in people living with HIV/AIDS. Neurological damage was identified to not only be caused by the viral infection itself but also through neurotoxic antiretroviral therapy (ART). PN is associated with a variety of risk factors; however, detailed knowledge is scarce for sub-Saharan African populations, bearing among the highest HIV/AIDS infection burden.In a cross-sectional study, we assessed the prevalence of PN in 525 adult outpatients suffering from HIV/AIDS and admitted to the largest tertiary hospital in Ghana. Through a detailed questionnaire and clinical examination including neurologic assessment and laboratory blood sample testing, this study investigated associations of PN with demographic and health determinants and identified risk factors associated with sensory neuropathy.The prevalence of PN in the Ghanaian cohort was 17.7% and increased odd ratios (OR) when patients were taller (> 1.57 m; OR = 3.84; 95% CI 1.38-10.66) or reached the age > 34 years (p = 0.124). Respondents with longer education duration had significantly less PN (≥ 9 years of education; OR = 0.49; 95% CI 0.26-0.92). The study also identified significant association of PN to both waist and hip girth and neutrophil counts. Curiously, higher adjusted odd ratios (aOR) of PN of patients under ART treatment were observed when CD4 lymphocytes were elevated (aOR = 0.81; 95% CI 0.36-1.83 and aOR = 2.17; 95% CI 0.93-5.05, for 300 and 600 counts, respectively). For patients on ART, an increase of 10 CD4 cell count units increased their chance of developing PN by 1% (aOR = 1.01; 95% CI 1.00 to 1.03).Despite current drug application regulations, prevalence of PN is still unacceptably high in sub-Saharan African populations. Reduction in chronic morbidity through a health system with routine monitoring, early diagnosis and prompt intervention, and effective case management can improve people living with HIV/AIDS' quality of life.

RESUMEN

BACKGROUND: The burden of end stage renal disease (ESRD) is reported to be higher among people of African ancestry. The majority do not have access to kidney transplantation. Africans, in general, are less likely to donate a kidney or receive a transplant. AIMS: This study surveyed public perceptions of kidney transplantation in an inner city and suburban communities in Ghana. It examined people's willingness to either accept or donate a kidney to save a life. In addition, it evaluated factors that influenced their opinion on the issue. METHODS: A cross-sectional survey was conducted in five purposively selected communities in the Greater Accra region in Ghana. Structured questionnaires and standardized instruments were administered to assess participants' socio-demographic characteristics, religiosity and spirituality, and perception of kidney transplantation. RESULTS: Of the 480 participants, 233 (48.5%) were willing to donate a kidney; 71.6% would only do so after death. Religion, loss of body part, and cultural values influenced participants' willingness to donate a kidney. Uncertainty of health status post-transplantation and uneasiness with the concept of transplantation influenced the participants' willingness to accept a kidney transplant. CONCLUSION: The study revealed that almost half of the participants hold positive views toward kidney transplantation.

RESUMEN

BACKGROUND: Buruli ulcer (BU) disease is a chronic debilitating skin disease caused by Mycobacteriumulcerans. It is associated with areas where the water is slow-flowing or stagnant. Policy makers take the necessary strategic and policy decisions especially where to target interventions based on available evidence including spatial distribution of the disease. Unfortunately, there is limited information on the spatial distribution of BU in Ghana. The aim of the study was to use Geographical Information System (GIS) technology to show the spatial distribution and hot spots of BU in Greater Accra and Eastern Regions in Ghana. The information could then be used by decision makers to make the necessary strategic and policy decisions, especially where to target intervention. METHODS: We conducted a community case search and spatial mapping in two districts in Eastern region (Akuapem South and Suhum- Kraboa-Coaltar) and two districts in Greater Accra region (Ga West and Ga South Municipalities) of Ghana to identify the spatial distribution of BU cases in the communities along the Densu River. These municipalities are already known to the Ministry of Health as having high case load of BU. Structured questionnaires on demographic characteristics, environmental factors and general practices were administered to the cases.Using the E-trex Garmin Geographical Positioning System (GPS), the location of the case patient was marked along with any important attributes of the community. ArcGIS was used to generate maps showing BU distribution and hot spots. RESULTS: Two hundred and fifty-seven (257) probable BU patients were enrolled in the study after the case search. These cases and their houses (or homes) were located with the GPS. The GIS maps generated showed a varying distribution of BU in the various communities. We observed clustering of BU patients downstream of the Densu River which had hitherto not been observed. CONCLUSIONS: There is clustering of BU in areas where the river was most contaminated. The identified hot spots for BU should be targeted for interventions by policy makers to ensure effective control of BU in Ghana.

RESUMEN

Background: Opportunistic infections (OIs) among newly diagnosed HIV patients are a marker for inadequateness of HIV awareness and testing. Despite global efforts at creating awareness for early detection, late HIV diagnosis and its associated OIs still exist. This study sought to determine the prevalence and patterns of OIs and associated factors among newly diagnosed HIV patients in Ghana. Methods: A retrospective study using data extraction was conducted among 423 newly diagnosed HIV patients aged ≥18 years at the Korle-Bu Teaching Hospital from July 1st 2018 to December 2019. Multivariate logistic regression was adopted to assess factors associated to OIs. Analysis was performed using SPSS version 16, and p-value < 0.05 was deemed significant. Results: The mean age of patients with a new HIV diagnosis was 40.15 ± 11.47 years. Male versus female sex differential was 30.3% and 69.7%, respectively. The prevalence of OIs among newly diagnosed HIV patients was 33.1% (95% CI = 34.6-44.1). About 70% (120/166) of patients with OIs were classified into WHO clinical stage III and IV. The most common OIs were candidiasis (oro-pharyhngeal-esophageal) (36.9%), and cerebral toxoplasmosis (19.9%). The odds of an OI at the time of HIV diagnosis among females was 51% lower than in males (aOR = 0.49, 95% CI = 0.28-0.86). Being employed increased the odds of OIs by 2.5 compared to the unemployed (aOR = 2.5; 95% CI = 1.11-5.61). Participants classified as World Health Organization (WHO) HIV clinical stage III and IV were 15.88 (95% CI = 9.41-26.79) times more likely to experience OIs. Conclusion: One in three patients newly diagnosed with HIV presented with an opportunistic infection, with men more likely to experience such infections. Significant attention should be given to improving case-finding strategies, especially among men.

RESUMEN

Background: Dolutegravir (DTG), a new antiretroviral drug, is being integrated into antiretroviral regimens for people with human immunodeficiency virus (PWH) in Ghana. There is little evidence of the effect of DTG on blood pressure (BP) levels in sub-Saharan Africa, especially West Africa. Our aim was to assess the incidence and predictors of hypertension (HTN) among PWH initiated on a DTG-based antiretroviral regimen in Ghana. Methods: An observational multicenter longitudinal study was conducted among PWH in Ghana from 2020 to 2022. BPs of nonhypertensive patients with BP ≤120/80 mm Hg at baseline were measured at 3, 6, 12, and 18 months post-DTG initiation. The primary outcome of the study was incidence of HTN, defined as BP ≥140/90 mm Hg. Kaplan-Meier estimator was used to estimate risk of developing HTN. Cox proportional hazards model with robust standard errors was used to estimate hazard ratios (HRs). Results: HTN prevalence among PWH screened was 37.3% (1366/3664). The incidence of de novo HTN among nonhypertensive PWH at 72 weeks was 598.4 per 1000 person-years (PY) (95% confidence interval [CI], 559.2-640.3) with incidence proportion of 59.90 (95% CI, 57.30-62.44). A quarter of those with de novo HTN developed it by month 6. Obesity (adjusted HR [aHR], 1.27 [95% CI, 1.05-1.54]), abnormal serum urea (aHR, 1.53 [95% CI, 1.27-1.85]), and low high-density lipoprotein (aHR, 1.45 [95% CI, 1.22-1.72]) were risk factors for HTN. Conclusions: Incidence of HTN was high among PWH on DTG. There is a need to monitor BP for HTN in adult PWH as well as traditional risk factors to reduce the burden of HTN and its complications.

RESUMEN

OBJECTIVE: Concentrations of tenofovir diphosphate (TFV-DP) and lamivudine triphosphate (3TC-TP) in cells are correlates of medication adherence and antiviral activity. However, studies have yet to characterize the simultaneous relationship between TFV-DP and 3TC-TP concentrations with HIV and hepatitis B virus (HBV) suppression. METHODS: Individuals with HIV/HBV coinfection on tenofovir disoproxil fumarate (TDF)-containing antiretroviral therapy (ART) were enrolled. Peripheral blood mononuclear cells (PBMCs) and dried blood spots (DBS) samples were collected and steady-state TFV-DP and 3TC-TP concentrations quantified using validated methods. The relationship between patient factors, TFV-DP, and 3TC-TP concentrations in PBMCs and DBS with HBV and HIV viral suppression were examined. RESULTS: Of 138 participants on TDF-containing ART for a median duration (range) of 6 (0.75-15) years, the median age was 43 years and 64% were women. Overall, 128 (92.8%) and 129 (93.5%) had suppressed HIV and HBV viral loads, respectively. Of the 128 participants with suppressed HIV, 122 (95.3%) had suppressed HBV. Self-reported ART adherence, recent change to dolutegravir-based ART, TFV-DP, and 3TC-TP concentrations in PBMCs and DBS were associated with HIV RNA suppression, while HBe antigen positivity, HIV suppression, and TFV-DP concentrations in DBS were associated with HBV DNA suppression (including six persons with HBV nonsuppression and HIV suppression). CONCLUSION: Long-term TDF/3TC-conatining ART was highly efficacious in individuals with HIV/HBV coinfection. Higher TFV-DP concentrations were predictive of suppression for both viruses. Persistent HBV viremia on TDF/3TC-containg ART requires additional research, but may represent poor adherence and the need for adherence interventions or novel antivirals.

RESUMEN

Background and Aim: Patients living with diabetes mellitus have a high burden of psychological distress such as depression and anxiety as well as impaired quality of life, which may negatively impact their adherence to medications, glucose control, and health-related costs.This study assessed the impact of quality of life and depression on medication adherence among patients with type 2 diabetes (type 2 diabetes mellitus [T2DM]) in a tertiary care setting in Ghana. Methods: The study was a cross-sectional study involving 238 patients with diabetes aged 18 years and above. Validated tools were used to assess medication adherence, depressive symptoms, and quality of life. Structural Equation Modeling was adopted to examine the mediation effect of quality of life on the relationship between depression and medication adherence among participants. Results: The mean age of the participants was 58.82 ± 13.49, and 169 (71.0%) out of a total of 238 respondents were females. Depression had a significant direct relationship with the quality of life of respondents [aß (95% confidence interval, CI) = -0.20 (-0.03, -0.00), p < 0.05; -0.21 (-0.41, -0.01) p < 0.05, respectively] and indirect relationship with quality of life [aß (95% CI) = -0.01 (-0.02, -0.004) p < 0.001]. Educational status and religion both showed a significant indirect relationship with quality of life [aß (95% CI) = 0.06 (0.07, 0.12), p < 0.05; 0.18 (0.01, 0.35) p < 0.05, respectively]. The mediating effect of quality of life on the relationship between depression and medication adherence was significant (Sobel = -3.19, p < 0.001). Conclusion: Depression, medication adherence, and quality of life were higher among older adults with T2DM. Depression was also found to have a strong negative association with both medication adherence and quality of life. Interventions to screen for depression and to improve the quality of life in patients living with diabetes are also recommended and this should go beyond the provision of standard treatments to explore further the mechanisms of this relationships.

RESUMEN

INTRODUCTION: Health care workers (HCWs) are crucial to the fight against COVID-19 and are at risk of being infected. We sought to determine the risk factors and associations of COVID-19 among HCWs in Ghana during the period of the pandemic. MATERIALS AND METHODS: A case-control study was conducted using the WHO COVID-19 HCWs exposure risk assessment tool. A HCW was categorized as "high risk" for COVID-19 if s/he did not respond "always, as recommended" to adherence to Infection Prevention and Control (IPC) measures during a healthcare interaction. A HCW was categorized as "low risk" if s/he responded "always, as recommended" to adherence to IPC measures. We used univariate and multiple logistic regression models to determine associated risk factors. Statistical significance was set at 5%. RESULTS: A total of 2402 HCWs were recruited and the mean age was 33.2±7.1 years. Almost 87% (1525/1745) of HCWs had high risk for COVID-19 infection. Risk factors identified were profession (doctor- aOR: 2.13, 95%CI: 1.54-2.94; radiographer-aOR: 1.16, 95% CI: 0.44-3.09)), presence of comorbidity (aOR: 1.89, 95%CI: 1.29-2.78), community exposure to virus (aOR: 1.26, 95% CI: 1.03-1.55), not performing hand hygiene before and after aseptic procedures performed (aOR: 1.6, 95% CI: 1.05-2.45); not frequently decontaminating high-touch surfaces always as recommended (aOR: 2.31, 95%CI: 1.65-3.22; p = 0.001) and contact with a confirmed COVID-19 patient (aOR: 1.39, 95% CI: 1.15-1.67). Among those who came into any form of contact with confirmed COVID-19 patient, providing direct care (aOR: 2.0, 95%CI: 1.36-2.94), face-to-face contact (aOR: 2.23, 95%CI: 1.41-3.51), contact with environment/materials used by COVID-19 patient (aOR: 2.25, 95%CI: 1.45-3.49) and presence during conduct of aerosol generating procedures (aOR: 2.73, 95%CI: 1.74-4.28) were associated with COVID-19 infection. CONCLUSION: Non-adherence to IPC guidelines puts HCWs at increased risk of COVID-19 infection thus ensuring IPC adherence is key to reducing this risk.

RESUMEN

Introduction: Antiretroviral therapy (ART) has reduced mortality and improved life expectancy among HIV patients but does not provide a cure. Patients must remain on lifelong medications and deal with drug resistance and side effects. This underscores the need for HIV cure research. However, participation in HIV cure research has risks without guaranteed benefits. We determined what HIV healthcare providers know about HIV cure research trials, the risks involved, and what kind of cure interventions they are likely to recommend for their patients. Methods: We conducted in-depth qualitative interviews with 39 HIV care providers consisting of 12 physicians, 8 counsellors, 14 nurses, 2 pharmacists, 2 laboratory scientists, and 1 community advocate from three hospitals. Interviews were transcribed verbatim and coded, and thematic analysis was performed independently by two investigators. Results: Participants were happy about the success of current treatments and hopeful that an HIV cure will be found in the near future, just as ART was discovered through research. They described cure as total eradication of the virus from the body and inability to test positive for HIV or transmit the virus. In terms of risk tolerance, respondents would recommend to their patients' studies with mild to moderate risks like what patients on antiretroviral therapy experience. Participants were reluctant to recommend treatment interruption to patients as part of a cure study and wished trials could be performed without stopping treatment. Healthcare providers categorically rejected death or permanent disability as an acceptable risk. The possibility of finding a cure that will benefit the individual or future generations was strong motivations for providers to recommend cure trials to their patients, as was transparency and adequate information on proposed trials. Overall, the participants were not actively seeking knowledge on cure research and lacked information on the various cure modalities under investigation. Conclusion: While hopeful for an HIV cure, healthcare providers in Ghana expect a cure to be definitive and pose minimal risk to their patients.

RESUMEN

Objective: The present study assessed the public's perception and Knowledge about COVID-19 and factors that could affect vaccine acceptability in Ghana. Design: We carried out a cross-sectional population-based study. A structured questionnaire was used to capture data on socio-demographic information, knowledge, and the public's perception of COVID-19 infection, as well as COVID-19 vaccine acceptability from consented participants. Factors affecting vaccine acceptability in Ghana were explored. Robust ordinary least square linear regression analysis was adopted to assess factors associated with vaccine acceptability. Setting: Five communities (Labone, Lartebiorkoshie, Old Fadama, Chorkor, and Ashiyie) in Accra in the Greater Accra district were selected. Participants: WHO modified cluster-sampling method was applied to select households of 997 participants in the five communities. Results: Most respondents were males (57.6%), and the median age of participants was 30 years. The study participants demonstrated a good knowledge of COVID-19 and had high perceptions of the COVID-19 pandemic. The results revealed that the highest educational level, marital status, self-rated Knowledge of COVID-19, Knowledge of COVID-19 definition, Knowledge of COVID-19 symptoms, and perception of the COVID-19 pandemic were significantly associated with vaccine acceptability. Self-reported impact of COVID-19 lockdown/movement restrictions on agriculture and job as a source of livelihood was associated with vaccine acceptability. Conclusion: Higher subjective and objective knowledge of COVID-19 increases vaccine acceptability scores significantly thus, education on COVID-19 and the vaccination against SARS-CoV-2 infection must be intensified to improve vaccine acceptability in Ghana, especially among those with lower educational backgrounds. Funding: None declared.

RESUMEN

OBJECTIVES: The COVID-19 pandemic had a disruptive impact on tuberculosis (TB) and HIV services. We assessed the in-hospital TB diagnostic care among people with HIV (PWH) overall and before and during the pandemic. METHODS: In this prospective study, adult PWH admitted at three hospitals in Ghana were recruited if they had a positive World Health Organization four-symptom screen or one or more World Health Organization danger signs or advanced HIV. We collected data on patient characteristics, TB assessment, and clinical outcomes after 8 weeks and used descriptive statistics and survival analysis. RESULTS: We enrolled 248 PWH with a median clusters of differentiation 4 count of 80.5 cells/mm3 (interquartile range 24-193). Of those, 246 (99.2%) patients had a positive World Health Organization four-symptom screen. Overall, 112 (45.2%) patients obtained a sputum Xpert result, 66 (46.5%) in the prepandemic and 46 (43.4%) in the pandemic period; P-value = 0.629. The TB prevalence of 46/246 (18.7%) was similar in the prepandemic 28/140 (20.0%) and pandemic 18/106 (17.0%) population; P-value = 0.548. The 8-week all-cause mortality was 62/246 (25.2%), with no difference in cumulative survival when stratifying for the pandemic period; log-rank P-value = 0.412. CONCLUSION: The study highlighted a large gap in the access to TB investigation and high early mortality among hospitalized PWH, irrespective of the COVID-19 pandemic.

RESUMEN

Introduction: tuberculosis (TB) is a major cause of morbidity and mortality in children in low- and middle-income countries. This study described the clinical presentation and identified factors contributing to poor outcome of childhood TB at Korle Bu Teaching Hospital (KBTH), Accra, Ghana. Methods: this was a retrospective cohort study of children aged ≤ 14 years with TB registered for treatment at KBTH from 2015 to 2019. Treatment outcomes were recorded as treatment success and unsuccessful outcomes (died and loss to follow-up). Multivariable logistics regression was conducted to assess factors associated with an unsuccessful outcome. Results: of 407 children with TB registered during the period, 269 (66.1%) patients had pulmonary tuberculosis (PTB). Of the 138 patients with extra-pulmonary TB (EPTB), 68 (49.3%) had TB lymphadenitis. The TB/HIV coinfection rate was 42.8%. The overall treatment success rate was 68.3%, whilst 71(17.4%) died, and 58 (14.3%) were lost to follow-up. Factors associated with death were age below 1 year (AOR: 3.46, 95% CI: 1.48-8.10, p=0.004) and having HIV coinfection (AOR: 1.89, 95% CI: 1.04-3.43, p=0.037). Factors associated with loss to follow-up were age below 1 year (AOR: 2.91, 95% CI: 1.12-8.59, p=0.029) and having EPTB (AOR: 2.40, 95% CI: 1.24-4.65, p=0.009). Conclusion: childhood TB treatment success in our population was below the national target of 85%, with high mortality and loss to follow-up rates, especially in younger children and those with HIV coinfection or EPTB. Tailored treatment strategies may be needed for children at risk of unsuccessful treatment outcome, especially among infants.

RESUMEN

Background: Hypertension is associated with high morbidity and mortality and this has been linked to poor treatment and control rates. To optimize drug treatment, patient-centered strategies such as coping, resilience, and adherence to medication may improve control rates and decrease the morbidity and mortality associated with hypertension. This study, therefore, assessed coping skills and resilience among patients with hypertension in Ghana. Methods: A cross-sectional study was conducted at Korle Bu Teaching Hospital. 224 consented patients with a diagnosis of hypertension were consecutively selected from the outpatient clinic. Questionnaires comprising socio-demographic characteristics, clinical parameters, Adult Resilience Measure, and the Africultural Coping Systems Inventory were administered. Data were analyzed using Stata version 16.1 and significance level was set at p-value of ≤ 0.05. Results: The mean age of participants was 62.03 ± 11.40 years and the majority were female (63%). The overall coping strategy mean score was 43.13 ± 13.57. For resilience, median relational and personal resilience (PR) scores were 32 (IQR-7) and 39 (IQR-9), respectively. Increased systolic BP significantly increases the overall coping strategy score. Collective coping strategy and systolic BP significantly increased coping scores (95%CI = 0.05-3.69 vs. 95%CI = 0.58-5.31). Overall coping strategy significantly increased personal and relational resilience (RR) domain scores by 0.004 (95%CI = 0.002-0.01) and 0.005 (95%CI = 0.003-0.006) units, respectively. This study demonstrated that Cognitive and emotional debriefing coping strategy was mostly used by patients with hypertension. Conclusion: Coping strategies had a positive and significant correlation with personal and RR, specifically collective and cognitive debriefing had a significant positive association with resilience among study participants. There is a need to actively put in measures that can improve the coping strategies and resilience among patients with hypertension to adjust to the long-term nature of the illness and treatment as this will promote better treatment outcomes.
