Depression among epileptic patients and its association with drug therapy in sub-Saharan Africa: A systematic review and meta-analysis.

ABSTRACT:

Background

Despite the high prevalence of epilepsy in sub-Saharan Africa and the established relationship between depression and epilepsy, the extent of comorbid epilepsy and depression in the region is still poorly understood. The objective of this systematic review and meta-analysis is to address this gap in the literature by determining the pooled prevalence of depression among epileptic patients in sub-Saharan Africa.

Methods

A systematic desk review and electronic web-based search of PubMed, Google Scholar, EMBASE, PsycINFO and the World Health Organization's Hinari portal (which includes the SCOPUS, African Index Medicus, and African Journals Online databases) conducted from December 2, 2017 to February 30, 2018, identified peer-reviewed, original research articles and doctoral dissertations using pre-defined quality and inclusion criteria. Relevant data were extracted and descriptive summaries of the studies presented in tabular form. The I2 statistic was used to assess heterogeneity across studies. Funnel plot asymmetry and Egger's tests were used to check for publication bias and the methodological quality of the included studies were assessed using the scale developed by Hoy and colleagues. The pooled prevalence of comorbidity at a 95% confidence interval (CI) was determined by applying a trim and fill analysis in a random-effects model.

Results

Our search identified 167 studies, of which 14 original research articles and two doctoral dissertations reporting on case-control and cross-sectional studies were eligible for inclusion in the final analysis. The pooled estimate of prevalence of depression among patients with epilepsy was 32.71% (95% CI: 25.50-39.91%). Regional sub-group analysis found that the pooled prevalence in East Africa was 34.52% (95% CI: 23.53-45.51%) and 29.69% (95% CI: 22.7-36.68%) in Southern and West Africa. The odds of depression among epileptic patients receiving polytherapy were 2.65 higher than in those receiving monotherapy (95% CI: 1.49-4.71, I2 = 79.1%, p < 0.05).

Conclusion

Our findings indicate high comorbidity in sub-Saharan Africa and suggest that it may be more prevalent there than elsewhere. Comorbidity is statistically associated with polytherapy in the studies reviewed. Given the high levels of comorbidity in the region, more attention should be paid to incorporating depression screening and treatment into existing epilepsy programs and to revising treatment guidelines on comorbid depression to reduce polytherapy.

Project description:BackgroundWith increasing adverse cardiovascular disease (CVD) outcomes in HIV/AIDS patients, the possible contribution of antiretroviral therapy (ART) to the prevailing CVD epidemic in sub-Saharan Africa (SSA) through its effect on CVD risk factors has rather been under investigated. This study aimed to assess the extent to which ART is associated with hypertension, diabetes mellitus (DM) and dyslipidemia in SSA.MethodsThis is a systematic review and meta-analysis of studies from SSA, published between January 1946 and December 2017, from Medline, Embase, Africa-wide Information, the Cochrane library, African Index and Medicus databases. Both observational and interventional studies with comparable ART-treated and ART-naïve populations were selected and data was extracted from eligible studies. Pooled estimates of the effect of ART on the outcomes of interest (hypertension, diabetes and abnormal lipid profiles) were obtained using random effects meta-analysis, and meta-regression analysis was used to explore between-study heterogeneity.ResultsTwenty cross-sectional studies were included involving 5386 participants. There was no association between ART use and hypertension (OR: 1.9, 95%CI: 0.96-3.76, n = 8, I2 = 73.8%) and DM (OR: 2.53, 95%CI: 0.87-7.35, n = 8, I2 = 73.8%). ART use was associated with high total cholesterol (OR: 3.85, 95%CI: 2.45-6.07, n = 8, I2 = 67.0%), high triglycerides (OR: 1.46, 95%CI: 1.21-1.75, n = 14, I2 = 10.0%) and high LDL-cholesterol (OR: 2.38, 95%CI: 1.43-3.95, n = 11, I2 = 87.6%). ART was associated with rather lower odds of having low HDL-cholesterol (OR: 0.53, 95%CI: 0.32-0.87, n = 8, I2 = 78.2%). There was evidence of between-study heterogeneity for all outcomes except high triglycerides.ConclusionsART appears to be associated with CVD risk in HIV/AIDS patients in SSA only through dyslipidemia but not through hypertension and DM, however, high quality and robust research in SSA is mandated to accurately ascertain the actual contribution of ART to the CVD burden in this part of the world. Nevertheless, HIV/AIDS patients should still benefit from systematic CVD screening alongside their regular care services.Trial registrationProspero Registration - CRD42016042306.

Project description:Sub-Saharan Africa represents 69% of the total number of individuals living with HIV infection worldwide and 72% of AIDS deaths globally. Pulmonary infection is a common and frequently fatal complication, though little is known regarding the lower airway microbiome composition of this population. Our objectives were to characterize the lower airway microbiome of Ugandan HIV-infected patients with pneumonia, to determine relationships with demographic, clinical, immunological, and microbiological variables and to compare the composition and predicted metagenome of these communities to a comparable cohort of patients in the US (San Francisco). Bronchoalveolar lavage samples from a cohort of 60 Ugandan HIV-infected patients with acute pneumonia were collected. Amplified 16S ribosomal RNA was profiled and aforementioned relationships examined. Ugandan airway microbiome composition and predicted metagenomic function were compared to US HIV-infected pneumonia patients. Among the most common bacterial pulmonary pathogens, Pseudomonas aeruginosa was most prevalent in the Ugandan cohort. Patients with a richer and more diverse airway microbiome exhibited lower bacterial burden, enrichment of members of the Lachnospiraceae and sulfur-reducing bacteria and reduced expression of TNF-alpha and matrix metalloproteinase-9. Compared to San Franciscan patients, Ugandan airway microbiome were significantly richer, and compositionally distinct with predicted metagenomes that encoded a multitude of distinct pathogenic pathways e.g secretion systems. Ugandan pneumonia-associated airway microbiome is compositionally and functionally distinct from those detected in comparable patients in developed countries, a feature which may contribute to adverse outcomes in this population. Please note that the data from the comparable cohort of patients in the USUS data was published as supplemental material of PMID: 22760045 but not submitted to GEO The 'patient_info.txt' contains 12 clinical, 7 immunological and 3 microbiological variables for each patient.

Project description:Postpartum depression (PPD) is a common mental health challenge in resource-constrained sub-Saharan Africa (SSA). Characterizing its correlates will aid prediction, early detection, and pre-emptive interventions. This review aimed to systematically synthesize and stratify PPD correlates in sub-Saharan Africa. The review was structured as per the Preferred Reporting Item for Systematic Reviews and Meta-Analyses. We included studies that reported the correlates of PPD in SSA. We searched PubMed, Medline, CINAHL, Academic Search Complete, and PsycINFO for relevant peer-reviewed literature. The correlates of PPD constituted the primary outcome. A random effect model was fitted to estimate the pooled correlation coefficient per correlate. The clinical relevance of correlates was stratified based on strength of correlation (r) and recurrence (f). The mean age of the participants was 27.0 ± 6.0 years, and 68.6% of participants had completed at least secondary education. The correlates of PPD in SSA were intimate partner violence (IPV) ((risk weight (rw) = 2.8; r = 0.212 (confidence interval (CI): 0.11-0.31), poor social support (PSS) (rw = 1.9; r = 0.250 (0.133-0.361)), unwanted pregnancy (UP) (rw = 1.6; r = 0.279 (CI: 0.14-0.41); I2 = 95.89), and maternal age (MA) (rw = 0.96; r = 0.27 (CI: 0.154-0.37)), among others. A cumulative risk weight of ⩾0.95 was predictive of PPD and marks the critical point at which preemptive interventions should be instituted. The stratification of risk PPD factors and computation of risk stability index are useful in identifying the clinical significant risk factors. The provision of critical risk point will simplify early detection thus facilitating cost-effectiveness. Of the correlates of PPD in SSA, IPV, PSS, UP, and MA are the most important. Targeted screening and pre-emptive interventions for women with high risk weight may be a reasonable strategy both in the short and long term.

Project description:In sub-Saharan Africa, cervical cancer is an intersecting epidemic with HIV and it is the second most common cause of cancer-related deaths in women. Therefore, this study was aimed to estimate the current status of the prevalence and associated factors of precancerous cervical lesions among HIV-positive women in sub-Saharan Africa. A systematic literature search was conducted from legitimate electronic databases, including MEDLINE (Ovid), PubMed, EMBASE (Ovid), Emcare (Ovid), CINAHL (EBSCOhost), Web of Science, Scopus, and PopLine and other gray literature including Google, Google Scholar, World Cat, ResearchGate, and Mednar. Data were extracted with a structured format prepared in Microsoft Excel. Each study was evaluated using the Joanna Briggs Institute critical appraisal tool for cross-sectional and cohort studies checklists. Accordingly, medium and high-quality studies were included in the review. Data synthesis and statistical analysis was conducted using OpenMeta and comprehensive meta-analysis version 2 software. The study protocol is registered on PROSPERO with ID: CRD42018114266. The pooled prevalence of precancerous cervical lesion among HIV-positive women in sub-Saharan Africa was 25.6% (95% confidence interval [CI]: 19.4%-31.8%). Having more than 2 lifetime sexual partners (odds ratio [OR]: 4.77; 95% CI: 1.35-16.93), having had a history of sexually transmitted infections (STIs; OR: 1.92; 95% CI: 1.03-3.57), having more than 2 births (OR: 1.84; 95% CI: 1.33-2.53), and CD4 count <200 cells/mm3 (OR: 1.765; 95% CI: 1.23-2.535) were significantly associated with precancerous cervical lesions. The prevalence of precancerous cervical lesion among HIV-positive women was high. One in 4 HIV-infected women suffers from precancerous cervical lesion. Lower CD4 cell count, STIs, multiple sexual partnering, and histories of multiple births and abortions were the foremost contributing factors for this burden. Precancerous cervical lesion could be reduced significantly if preventive and promotive measures are done on the associated factors.

Project description:IntroductionEven though breast cancer incidence is lower in Sub-Saharan Africa, its mortality is higher in these countries. However, the impact does not end with diagnosis and treatment; rather many patients struggle with depression which is very common among these patients. This systematic review and meta-analysis helps to provide valuable insights into the overall prevalence of depression and associated factors among breast cancer patients in Sub-Saharan Africa.MethodWe searched several databases, including MEDLINE, Embase, Scopus, Hinary, CINHAL and Google Scholar to retrieve relevant literatures from inception up to 15 June 2023. All observational studies, published in English at any time were included, while, letters to editor, review articles, commentaries, interventional and qualitative studies, and, abstracts presented in conferences or seminars were excluded. The results of this systematic review and meta-analysis have been written based on the PRISMA 2020 checklist and the protocol have been registered in PROSPERO database (CRD42023428910).ResultWe have included nine articles with 2226 study participants. The result showed that, the pooled prevalence of depression among breast cancer patients in Sub-Saharan Africa was 45.6% (95% CI: 30%-61%) with significant heterogeneity I2 = 98.9%, (Cochrane) Q < 0.0001. There was no single study effect and publication bias but substantial heterogeneity was observed. In addition, there has been a publication bias with eggers test (p < 0.0033). However, there were no studies imputed after trim and fill analysis. From the factors, breast cancer patients who had poor financial support were 1.47 (95% CI: 1.02-2.13) times more at risk of developing depression than their counterparts.ConclusionThe prevalence of depression among breast cancer patients in Sub-Saharan Africa countries were higher than other regions. Thus, Emphasis should be given on developing financial assistance programs designed to cover the medical costs and improving the health care infrastructure.
