Prevalence and correlates of modifiable risk factors for cervical cancer and HPV infection among senior high school students in Ghana: a latent class analysis.

BACKGROUND: While health risk behaviours are likely to co-occur, there is dearth of studies exploring the clustering of cervical cancer and HPV infection risk factors among adolescents. This study aimed to determine: 1) the prevalence of modifiable risk factors for cervical cancer and HPV infection, 2) the clustering of modifiable risk factors for cervical cancer and HPV infection, and 3) factors associated with the identified clusters. METHODS: Female students (aged 16-24 years, N = 2400) recruited from 17 randomly selected senior high schools in the Ashanti Region, Ghana completed a questionnaire assessing modifiable risk factors for cervical cancer and HPV infection including sexual experience, early sexual intercourse (< 18 years), unprotected sex, smoking, sexually transmitted infections (STIs); multiple sexual partners (MSP) and smoking. Latent class analysis explored separate classes of students according to their risk factor profiles for cervical cancer and HPV infection. Latent class regression analysis explored factors associated with latent class memberships. RESULTS: Approximately one in three students (34%, 95%CI: 32%-36%) reported exposure to at least one risk factor. Two separate classes emerged: high-risk and low-risk (cervical cancer: 24% and 76% of students, respectively; HPV infection: 26% and 74% of students, respectively). Compared to participants in the low-risk classes i) the cervical cancer high-risk class were more likely to report exposure to oral contraceptives; early sexual intercourse (< 18 years); STIs; MSP and smoking; and ii) the HPV infection high risk class were more likely to report exposure to sexual intercourse; unprotected sex and MSP. Participants with higher risk factor knowledge had significantly higher odds of belonging to cervical cancer and HPV infection high-risk classes. Participants with greater perceived susceptibility to cervical cancer and HPV infection were more likely to belong to the high-risk HPV infection class. Sociodemographic characteristics and greater perceived seriousness about cervical cancer and HPV infection had significantly lower odds of belonging to both high-risk classes. CONCLUSIONS: The co-occurrence of cervical cancer and HPV infection risk factors suggests that a single school-based multi-component risk reduction intervention could concurrently target multiple risk behaviours. However, students in the high risk class may benefit from more complex risk reduction interventions.

Ambulatory end-stage liver disease in Ghana; patient profile and utility of alpha fetoprotein and aspartate aminotransferase: platelet ratio index.

BACKGROUND: End-stage liver disease (ESLD) is a major burden on public health, particularly in sub-Saharan Africa, where hepatitis B virus (HBV) is an important risk factor. We aimed to describe clinical characteristics of ESLD from cirrhosis or hepatocellular carcinoma (HCC) and the performance of aspartate aminotransferase (AST)-platelet ratio index (APRI) and alpha fetoprotein (AFP) in Ghana. METHODS: We performed an observational cross-sectional study in outpatient hepatology clinics at three teaching hospitals in Ghana, West Africa. One hundred and forty-one HCC, 216 cirrhosis and 218 chronic HBV patients were recruited by convenience sampling. Sociodemographic, history and examination, laboratory, and disease staging information were shown using descriptive statistics. Performance of the APRI score in diagnosis of cirrhosis and AFP in the diagnosis of HCC was determined using AUROC analysis. RESULTS: Median age at presentation was 44 years for HCC and 46 years for cirrhosis. HBV was found in 69.5% of HCC and 47.2% of cirrhosis cases, and HCV in 6.4% and 3.7% respectively. APRI cut-off of 2 had sensitivity of 45.4% and specificity of 95% in diagnosis of cirrhosis, and cut-off of 1 had sensitivity of 75.9% and specificity of 89%. AUC of AFP was 0.88 (95% CI 0.81-0.94) in diagnosis of HCC. Low monthly income was associated with lower odds of undertaking AFP. Thirty one percent of cirrhotic persons were Child-Pugh C, and 67.9% of HCC patients had advanced or terminal disease at presentation. CONCLUSIONS: Our findings emphasize the young age of ESLD patients in Ghana and the advanced nature at presentation. It highlights shortcomings in surveillance and the need for policies to address the burden and improve outcomes in Ghana.

Views of Service Users, Their Family or Carers, and Health Care Professionals on Telerehabilitation for People With Neurological Conditions in Ghana: Qualitative Study.

BACKGROUND: Up to 50% of people in low- and middle-income countries do not receive the rehabilitation they require. Telerehabilitation has the potential to improve access to neurorehabilitation services especially in low- and middle-income countries. Although there are reports of the barriers and facilitators to telerehabilitation in such settings, almost all are anecdotal. Furthermore, family or carers have a significant influence on the adoption and success of telerehabilitation, but their views have not been reported. OBJECTIVE: This study aimed to investigate the views of service users, their family or carers, and health care professionals (HCPs) on telerehabilitation for people with neurological conditions in Ghana. METHODS: Two focus groups were held at Komfo Anokye Hospital in Kumasi, Ghana: one in person for service users (n=11) and their family or carers (n=9), conducted in the Ghanaian language of Twi, and one hybrid for HCPs (n=18) conducted in English. The mean (SD) age of the service users was 59.8 (8.6) years; 5 users had a stroke and 6 had Parkinson disease. The HCP group consisted of 7 speech and language therapists, 3 physiotherapists, 3 occupational therapists, 3 medical staff, 1 nurse, and 1 industry representative. Focus groups were semi-structured and explored previous experiences of telerehabilitation, perceived benefits and challenges, and solutions to overcome these challenges. Focus groups were audio transcribed, and the service user transcript was translated into English. The resulting transcripts were analyzed using thematic analysis. RESULTS: Overall, participants were positive about the role of telerehabilitation but recommended hybrid delivery, with in-person rehabilitation in the early stages and telerehabilitation in the later stages. In relation to telerehabilitation in Ghana, there were 3 main themes: benefits, challenges or barriers, and implementation. Benefits included the convenience and lower cost for service users, the higher dose of therapy possible, and increased access for people in remote areas. However, challenges included lack of a stable internet connection, cost of phones and data packages, and low levels of literacy. Implementation issues included cultural relevance, information governance, and the platform used to deliver telerehabilitation, with most participants being familiar with WhatsApp. CONCLUSIONS: Telerehabilitation has the potential to be a useful method of delivering rehabilitation to people with neurological conditions in Ghana, especially in a hybrid rehabilitation model with telerehabilitation augmenting in-person sessions. However, many people were unaware of telerehabilitation, and challenges such as a reliable internet connection, cultural relevance, and costs need to be addressed. Clinical trials of low-cost telerehabilitation interventions contextualized to the specific user group are required.

Very low prevalence of Mansonella perstans-specific cell-free DNA in serum samples of Ghanaian HIV patients.

Background: Mansonellosis is a widely neglected helminth disease which is predominantly observed in tropical regions. This study was conducted to assess potential associations of the prevalence of circulating Mansonella perstans-specific cell-free DNA in human serum and HIV infection in Ghanaian individuals. Methods: For this purpose, serum samples obtained from Ghanaian HIV-patients (n = 989) and non-HIV-infected Ghanaian control individuals (n = 91) were subjected to real-time PCR targeting the ITS-(internal transcribed spacer-)2 sequence of M. perstans and Mansonella sp. Deux. Results: Mansonella-specific cell-free DNA was detected in serum samples of only 2 HIV-positive and 0 HIV-negative individuals, making any reliable conclusions on potential associations between HIV and mansonellosis in tropical Ghana unfeasible. Conclusions: Future epidemiological studies on hypothetical associations between mansonellosis and HIV infections should focus more specifically on high-endemicity settings for both Mansonella spp.-infections and HIV-infections, include higher case numbers and be based on real-time PCR from whole blood rather than from serum, in which only circulating parasite DNA but no more cell-bound parasite DNA can be detected. However, the study did not show associations of HIV infections in Ghanaian individuals with Mansonella worm loads high enough to detect cell-free Mansonella DNA in serum by PCR.

The Clinical Features and Immunological Signature of Cyclospora cayetanensis Co-Infection among People Living with HIV in Ghana.

Background: There is a paucity of information on the contemporary burden, disease patterns, and immunological profile of people living with HIV who are co-infected with C. cayetanensis in the post-antiretroviral therapy era. Methods: For this cross-sectional study, stool samples of 640 HIV-positive and 83 HIV-negative individuals in Ghana were tested for C. cayetanensis. Additionally, sociodemographic parameters, clinical symptoms, medical drug intake, and immunological parameters were assessed. Results: The prevalence of C. cayetanensis was 8.75% (n = 56) in HIV-positive and 1.20% (n = 1) in HIV-negative participants (p = 0.015). Within the group of HIV-positive participants, the prevalence reached 13.6% in patients with CD4+ T cell counts below 200 cells/µl. Frequencies of the clinical manifestations of weight loss and diarrheal disease were significantly higher in patients with C. cayetanensis compared to those without co-infection (36.36% vs. 22.59%, p = 0.034 and 20.00% vs. 4.90%, p < 0.001, respectively). The expression of markers of immune activation and exhaustion of T lymphocyte sub-populations was significantly elevated in patients colonized with C. cayetanensis. Conclusions: In the modern post-combined antiretroviral therapy (cART) era, the acquisition of C. cayetanensis among PLWH in Ghana is driven largely by the immunosuppression profile characterized by high expression of markers of immune activation and immune exhaustion.

Screening for Schistosoma spp. and Leishmania spp. DNA in Serum of Ghanaian Patients with Acquired Immunodeficiency.

Both Schistosoma spp. (species) and Leishmania spp. are prevalent in Ghana in West Africa. However, little is known about their local occurrence in immunocompromised individuals. In the study presented here, the real-time PCR-(polymerase chain reaction-)based screening for repetitive DNA (deoxyribonucleotide acid) sequences from the genomes of Leishmania (L.) spp. and Schistosoma (S.) spp. was performed in the serum of HIV-(human immunodeficiency virus-)infected Ghanaian patients. In 1083 assessed serum samples from HIV-positive and HIV-negative Ghanian patients, Leishmania spp.-specific DNA was not detected, while the diagnostic accuracy-adjusted prevalence estimation suggested a 3.6% prevalence of the S. mansoni complex and a 0.5% prevalence of the S. haematobium complex. Associations of schistosomiasis with younger age, as well as with the male sex, could be shown but not with an HIV status. Weakly significant signals for the associations of schistosomiasis with an increased viral load, reduced CD4+ (CD = cluster of differentiation) T cell count, and a reduced CD4+/CD8+ ratio could be observed but was inconsistently lost in the case of the stratification on the species complex level. So, it is concluded that factors other than HIV status are more likely to have influenced the occurrence of Schistosoma spp. infections in the assessed Ghanaian patients. Potential associations between HIV infection-associated factors, such as the viral load and the immune status of the patients, for which weak signals were observed in this hypothesis-forming retrospective assessment, should be confirmed by prospective, sufficiently powered investigations.

Contemporary trends in HIV-associated neurocognitive disorders in Ghana.

BACKGROUND: Widespread introduction of early combination antiretroviral therapy (cART) for People Living with HIV (PLWH) will influence the burden, profile, and trajectory of HIV-associated neurocognitive disorders (HAND) in the 21st century. OBJECTIVES: To assess the prevalence and trajectory of HAND among PLWH in a Ghanaian tertiary medical center. METHODS: We analyzed the dataset of a study involving PLWH established on cART (n = 256) and PLWH not initially on cART (n = 244). HIV-negative individuals (n = 246) served as normative controls for neurocognitive assessments. HAND was defined according to the Frascati criteria into asymptomatic neurocognitive impairment (ANI), mild neurocognitive disorder (MND) and HIV-associated dementia (HAD) at enrollment and at month 12. Multivariate logistic regression models were fitted to identify factors associated with HAND. RESULTS: Among PLWH on cART, 21.5%, 3.5% and 0.0% had ANI, MND and HAD respectively compared with 20.1%, 9.8% and 2.0% among PLWH cART naïve, p < 0.0001. Overall, 71.6%, 20.8%, 6.6% and 1.0% had no cognitive impairment, ANI, MND and HAD at baseline. Among participants who completed month 12 follow-up, 55.2% had no cognitive impairment, 43.5%, 1.2%, 0.0% had ANI, MND and HAD respectively, p < 0.0001. Adjusted odds ratio (95% CI) of six independent predictors of HAND at month 12 were no education (3.29;1.81-6.00), stage 4 disease (4.64;1.37-15.69), hypertension (2.28;1.10-4.73), nevirapine use (2.05;1.04-4.05), baseline viral load (0.66;0.56-0.77), and cigarette use (0.10; 0.03-0.42). CONCLUSION: Most Ghanaian patients in the post-cART era with HAND had mild neurocognitive impairments. The impact of hypertension on progression of HAND warrants further evaluation in our settings.

Evaluation of Vascular Event Risk while on Long-term Anti-retroviral Suppressive Therapy [EVERLAST]: Protocol for a prospective observational study.

BACKGROUND & OBJECTIVE: Cardiovascular disease (CVD) risk among the HIV population is high due to a combination of accelerated atherosclerosis from the pro-inflammatory milieu created by chronic HIV infection and the potentially adverse metabolic side effects from cART (combination antiretroviral therapy) medications. Although sub-Saharan Africa (SSA) bears 70% of the global burden of HIV disease, there is a relative paucity of studies comprehensively assessing CVD risk among people living with HIV on the continent. The overarching objective of the Evaluation of Vascular Event Risk while on Long-term Anti-retroviral Suppressive Therapy (EVERLAST) Study is to characterize the burden of CVD among HIV patients on ART in Ghana, and explore factors influencing it. METHODS: The EVERLAST study incorporates prospective CVD risk assessments and a convergent mixed methods approach. This prospective study will evaluate CVD risk by measuring Carotid Intimal Media Thickness (CIMT) and presence of traditional medical and lifestyle vascular risk among 240 Ghanaian HIV patients on antiretroviral therapy compared with age- and sex-matched HIV uninfected (n = 240) and HIV positive ART naïve controls (n = 240). A contextual qualitative analysis will also be conducted to determine attitudes/perceptions of various key local stakeholders about CVD risk among HIV patients. The primary outcome measure will be CIMT measured cross-sectionally and prospectively among the three groups. A host of secondary outcome variables including CVD risk factors, CVD risk equations, HIV associated neurocognitive dysfunction and psychological well-being will also be assessed. CONCLUSION: EVERLAST will provide crucial insights into the unique contributions of ART exposure and environmental factors such as lifestyle, traditional beliefs, and socio-economic indicators to CVD risk among HIV patients in a resource-limited setting. Ultimately, findings from our study will be utilized to develop interventions that will be tested in a randomized controlled trial to provide evidence to guide CVD risk management in SSA.

Nutritional management of cirrhosis patients: A qualitative study exploring perceptions of patients and health workers in Ghana.

BACKGROUND AND AIMS: Malnutrition is common among patients with end stage liver disease including liver cirrhosis and liver cancer. Optimal nutrition is important to reduce morbidity and mortality of these patients. There is limited qualitative data on nutritional status and management of chronic liver disease patients. We aimed to explore the knowledge, opinions and practices of cirrhosis patients and health workers in nutritional management of cirrhosis in Ghana, in order to determine whether there is a need to improve nutritional care for cirrhosis patients. METHODS: We conducted a qualitative study using semi-structured interviews of cirrhotic patients (n = 16) and healthcare providers (n = 27) in three academic centers in Accra, Kumasi and Cape Coast (Ghana). Recruitment was by purposive sampling of patients attending specialist liver disease clinics. The recorded data were analyzed using NVivo 11 software, with generation of codes, themes and subthemes. RESULTS: The major themes that emerged from the data included nutrition as part of care delivery during the hospital visit, nutritional recommendations, dietary changes and long-term practice improvement. The results showed that patients and health workers felt dietary recommendations for patients were frequently addressed, but could be significantly improved. We found that in the opinion of study participants, local guidelines are important and necessary in nutritional management of cirrhosis patients, and that participants felt it was difficult to change dietary habits following cirrhosis diagnosis. CONCLUSIONS: These results suggest that nutritional management of cirrhosis patients in Ghana requires improvement. Strategies to improve this could include a multi-disciplinary approach to nutritional management, development of local guidelines and continued nutritional assessment, monitoring and follow-up.

Burden of subclinical carotid atherosclerosis and vascular risk factors among people living with HIV in Ghana.

BACKGROUND: The burden of cardiovascular disease (CVD) among people living with HIV (PLWH) in sub-Saharan Africa is projected to rise due to a rapid epidemiological transition and improved treatment of HIV infection on the sub-continent. OBJECTIVE: The Evaluation of Vascular Event Risk while on Long-term Anti-retroviral Suppressive Therapy (EVERLAST) Study sought to assess the extent of subclinical atherosclerosis and characterize the nature of CVD risk factors among HIV patients on Antiretroviral therapy (ART) in Ghana. METHODS: We conducted a cross-sectional study involving HIV patients on antiretroviral therapy (n = 250) in comparison with HIV positive ART naïve (n = 201), and HIV uninfected controls (n = 250). We assessed prevalence of hypertension, dyslipidemia, diabetes mellitus, central obesity, and carotid atherosclerosis using B-mode carotid Doppler ultrasonography. We assessed factors associated with subclinical atherosclerosis defined by a carotid intimal media thickness (CIMT) cut-off of ≥0.78 mm among PLWH using a logistic regression model. RESULTS: Mean age of PLWH on combination ART (cART) was 45.7 ±â€¯8.6 years, 42.9 ±â€¯8.8 years among PLWH not on cART, and 44.9 ±â€¯9.5 years among HIV negative controls of which 81.2%, 81.6% and 81.1% respectively were females. Prevalence of subclinical atherosclerosis at the common carotid artery in the three groups was 67.6%, 66.7% and 62.4%, p = 0.43. Among PLWH, raised serum total cholesterol (OR 1.16, 95% CI: 1.00-1.35) and triglycerides (OR 1.32, 95% CI: 1.01-1.73) were significantly associated with subclinical atherosclerosis. Prevalence of vascular risk factors among PLWH on cART, PLWH cART naïve, and HIV negative controls respectively were as follows: dyslipidemia- 79.5%, 83.1%, and 73.5%, p = 0.04; hypertension- 40.2%, 23.4%, and 44.9%, p < 0.0001; central obesity-61.8%, 66.7%, and 78.2%, p < 0.0001; diabetes mellitus-6.8%, 5.5% and 4.9%, p = 0.53. CONCLUSION: Overall while there is a high baseline prevalence of CVD risk factors in the Ghanaian population, serum lipid derangements appear to be more prevalent among HIV infected patients, and are linked to sub-clinical atherosclerosis. Future studies need to confirm these findings, explore the underlying pathophysiology, and optimize treatment strategies to avert untoward CVD outcomes.
