The COVID-19 pandemic has adversely affected tuberculosis (TB) care delivery in high burden countries. We therefore conducted a retrospective study to assess the impact of COVID-19 on TB case detection and treatment outcomes at the Chest Clinic at Connaught Hospital in Freetown, Sierra Leone. Overall, 2300 presumptive cases were tested during the first three quarters of 2020 (intra-COVID-19) versus 2636 in 2019 (baseline), representing a 12.7% decline. Testing declined by 25% in women, 20% in children and 81% in community-initiated referrals. Notwithstanding, laboratory-confirmed TB cases increased by 37.0% and treatment success rate was higher in 2020 (55.6% vs. 46.7%, p = 0.002). Multivariate logistic regression analysis found that age < 55 years (aOR 1.74, 95% CI (1.80, 2.56); p = 0.005), new diagnosis (aOR 1.69, 95% CI (1.16, 2.47); p = 0.007), pulmonary TB (aOR 3.17, 95% CI (1.67, 6.04); p < 0.001), HIV negative status (aOR 1.60, 95%CI (1.24, 2.06); p < 0.001) and self-administration of anti-TB drugs through monthly dispensing versus directly observed therapy (DOT) (aOR 1.56, 95% CI (1.21, 2.03); p = 0.001) independently predicted treatment success. These findings may have policy implications for DOTS in this setting and suggest that more resources are needed to reverse the negative impact of the COVID-19 pandemic on TB program activities in Sierra Leone.

Globally, over 280 million individuals suffer from mental disorders, and almost 85% in low-resource settings do not receive any therapy. In sub-Saharan Africa (SSA), many patients are forced to either live with untreated mental illness or seek care from traditional or religious leaders due to the high treatment cost. This literature review identifies pathways to access mental health services and proposed a collaborative model for care across SSA. We systematically searched five electronic databases (Embase and MEDLINE via OVID, CINAHL, PsycINFO, and Global Index Medicus) using the following search terms, ‘pathways to care’, ‘mental disorders,’ and ‘sub-Saharan Africa’ for primary studies reporting on pathways to care for mental disorders in SSA. There were no restrictions on the study’s date. Overall, the electronic database search produced 3399 search results, of which we retrieved 194 articles for full-text screening and 29 studies included in the analysis. This study finds that traditional and faith-based healers play an integral role in the pathway to care; more than 70% used traditional and religious healers as the first point of care for mental health care. The median duration for the delay in seeking treatment in a health facility was six months. Patients who sought care from traditional and faith healers were found to have experienced the most prolonged delay without treatment. Age, gender, level of education, marital status, and geographical location were some of the factors associated with the pathway choice. Patients who sought care from traditional and faith healers as the first point of care were found to have experienced the most extended delay without treatment when they arrived at the hospital. The study proposes and recommends a new model for collaboration between biomedical, traditional and faith-based healers that focuses on education through training and adopting a new referral framework.

Background: Advanced HIV disease (AHD) in young people living with HIV (PLHIV) is an increasingly pressing public health issue in sub-Saharan Africa. Despite global progress in early HIV testing and reducing HIV-related deaths, many youths experience increased rates of HIV disease progression in sub-Saharan Africa. This study describes the burden, clinical manifestations, and factors for disease progression among young PLHIV aged 15 – 24 years seeking medical services at a major public hospital in Sierra Leone. Methods: We performed a cross-sectional analysis of routinely collected data for PLHIV patients aged 15 to 24 seen at Connaught Hospital in Sierra Leone between September 2022 and March 2023. We estimated the proportion of AHD in young PLHIV and performed logistic regression modelling to explore predictors of AHD. The statistical significance level was set at 0.05 for all statistical tests. Results: Of the 581 PLHIV that were reported, 238 (40.9%) were between the ages of 15 and 24 years, with a median age of 22 (20—24), and 151 (63.5%) were females. On review, 178 (74.8%) has initiated antiretroviral therapy regimen (ART); 117 (65.7%) were actively on ART for ≤ 6 months, while 114 (64%) had interruptions with their ART treatment. The overall prevalence of AHD was 41.6% (99/238); 46.7% (35/68) of young PLHIV at the HIV clinic, and 39.3% (64/163) of admission. Sex—Female (OR, 0.51; 95% CI, 0.28–0.94; p = 0.030), and Tertiary Education level (OR, 0.27; 95% CI, 0.10 – 0.78; p = 0.015) have significantly lower odds of AHD in the entire study population. While for inpatients, Age (young Adults) of PLHIV (OR, 1.23; 95% CI, 1.00–1.52; p = 0.047) had 1.23 times the odds of AHD compared to adolescents, and being female (OR, 0.27; 95% CI, 0.08–0.84; p = 0.024), Overweight—Body mass index (OR, 0.10; 95% CI, 0.01–0.77; p = 0.028), Tertiary Education level (OR, 0.08; 95% CI, 0.01–0.52; p = 0.008) have significantly lower odds of AHD. Common conditions reported for the AHD group in the medical wards are tuberculosis (13.58%), hepatitis B (6.13%), Kaposi sarcoma (3.07%), and oesophagal candidiasis (2.45%). Conclusion: We reported a high prevalence of advanced HIV among young patients in a tertiary Hospital in Sierra Leone. One in two young PLHIV aged 15 to 24 years reported AHD, emphasizing the need to strengthen public health measures that address access to and retention of HIV services.

Limited diagnostic capacity for detecting asymptomatic malaria infections with low parasite densities hinders elimination efforts in Africa. Here, we adapt a near point-of-care, LAMP-based diagnostic platform for malaria diagnosis using capillary blood. This Pan/Pf detection method meets the Malaria Eradication Research Agenda (malERA) criteria for community-level screening, with a limit of detection of 0.6 parasites/μL and a sample-to-result time under 45 minutes. We evaluate its performance on 672 capillary blood samples collected at the community level in The Gambia and Burkina Faso, including 146 Plasmodium falciparum positives confirmed by qPCR. The diagnostic platform achieved 95.2% sensitivity (95% CI: 90.4–98.1) and 96.8% specificity (95% CI: 94.9–98.0). It also detected 94.9% (130/137) of asymptomatic infections and 95.3% (41/43) of submicroscopic cases (<16 parasites/μL), outperforming expert microscopy (70.1% and 0%) and rapid diagnostic tests (49.6% and 4.7%). This field-deployable molecular diagnostic method offers a sensitive, scalable solution to support test-and-treat strategies for malaria elimination across Africa.

Background: HIV infection rates are relatively low in Sierra Leone and in West Africa but the contribution of HIV to the risk factors for stroke and outcomes is unknown. In this study, we examined stroke types, presentation, risk factors and outcome in HIV stroke patients compared with controls.Methods: We used data from the Stroke in Sierra Leone Study at 2 tertiary hospitals in Freetown, Sierra Leone. A case control design was used to compare stroke type, presentation, risk factors and outcome in sero-positive HIV patients with HIV negative stroke controls. Controls were matched for age and gender and a 1:4 ratio cases to controls was used to optimize power. Analysis was performed using the Pearson x2 for categorical variable, Paired-T test and Mann-Whitney U test for continuous variables. A p-value of less than 0.05 was taken as the level of statistical significance.Results: Of 511 (51.8%) stroke patients tested for HIV, 36 (7.1%) were positive. Univariate unmatched analysis showed a stroke mean age of 49 years in HIV-positive versus 58 years in HIV-negative population (p = <0.001). In the case-control group, ischaemic stroke is the major type reported in both populations, HIV-negative pop-ulation: 77 (53.5%) versus HIV-positive: 25 (69.4%) (p = 0.084). Hypertension is the most prevalent risk factor in both groups, HIV-positive: 23 (63.9%) versus HIV-negative: 409 (86.1%) (p = 0.001). Lower CD4+ count is associated in-hospital mortality (p = <0.001).Conclusion: These findings support the current call for timely management of stroke and HIV through integrated care.
