Background: Obesity is linked to non-communicable conditions. We looked at obesity using four definable criteria and their relationship to biochemical and inflammatory indicators of cardiovascular diseases (CVDs) in people living with HIV (PLHIV)., Methodology: This cross-sectional study involved 140 randomly selected HIV-infected patients attending HIV clinics at the Jos University Teaching Hospital and Faith Alive Foundation in Jos, Nigeria. Anthropometric measurements such as height, weight, waist circumference, and hip circumference were taken to identify those with obesity. Fasting plasma glucose, lipid profile, High-sensitivity CRP (hsCRP), and HIV-related markers were evaluated., Result: The mean (SD) age of the participants was 42.5 (8.8) years, and the majority (71.4%) were females. The prevalence of Obesity based on Body-Mass-Index (BMI), International Diabetes Federation (IDF), Adult Treatment Panel (ATP), and Waist-Hip-Ratio (WHR) criteria were 18.6%, 50.7% 34.3%, and 45.7% respectively. Obesity concordance among the criteria for obesity was highest between IDF and ATP (Kappa= 0.673, p<0.001); and least between BMI vs WHR (Kappa= 0.124, p<0.073). Only 9.3% had obesity by all 4 criteria. BMI was independently associated with hypertension but not glycaemic status nor dyslipidaemia while Obesity by WHR was significantly associated with hypertension and dyslipidaemia, after adjusting for age and sex. There was no significant association between Obesity by all the criteria and HIV-related parameters such as duration of HIV infection, Antiretroviral (ARV) use, and CD4 counts (p>0.05)., Conclusion: Our study urges a unified assessment of obesity and a more prominent use of parameters of central obesity, for assessing cardiovascular risk in PLHIV., Competing Interests: The authors declare no competing interests., (Copyright © 2024 Nigerian Medical Association.)

Background: Both HIV infection and antiretroviral therapy (ART) may be associated with metabolic complications including bone loss. To further inform guidance on screening and treatment of bone disease, we evaluated the impact of HIV and ART on vitamin D (VD) levels and bone mineral density (BMD) among HIV-infected and uninfected Nigerians., Methods: We carried out a cross-sectional study of HIV-infected participants and uninfected matched controls, who were recruited from a large clinical site in Jos, Nigeria. Calcaneal ultrasonography was used to assess BMD. VD levels were determined using electrochemiluminescence binding assay, with vitamin D deficiency (VDD) defined as <25 ng/ml., Results: There were 241 participants (61 ART-experienced, 60 ART-naïve, and 120 HIV-uninfected), and the mean age was 39±10 years; 66% were female. VDD was present in 70.5% (95% CI:64.3–76.2%) of all participants; occurring in 70.0% of ART-experienced, 73.0% of ART-naïve and 69.0% of HIV-uninfected controls (p = 0.84). Overall, the prevalence of low BMD was 21.1% (95% CI: 16.1–26.8%); being present in 24.5% of ART-experienced, 26.6% of ART-naïve and 16.6% of HIV-uninfected controls (p = 0.22). Only female sex (OR 6.82; 95% CI:1.93–24.0, p <0.001) was significantly associated with low BMD in the HIV group. No HIV-specific factor including ART use and type was associated with low BMD., Conclusion: VDD and low BMD are both prevalent among HIV-infected and uninfected individuals in Nigeria. HIV, ART use, and VDD were not associated with low BMD., Competing Interests: The Authors declare that no competing interest exists., (Copyright © 2023 by West African Journal of Medicine.)

Background: The COVID-19 pandemic has led to hundreds of thousands of deaths worldwide., Aims: Being a novel viral disease, we sought to evaluate the knowledge and practice of doctors and nurses in a tertiary hospital regarding the disease., Subjects and Methods: Using a self-administered questionnaire, respondents were asked questions on the cause, clinical features, and prevention of COVID-19., Results: : We studied 409 respondents (238 doctors and 171 nurses) with a mean age of 34 ± 7 years and a median length of experience of five (IQR 2-9) years. The mean knowledge score was 9.6 ± 1.2 out of a maximum of 12 points with 337 (82.4%) respondents having good knowledge. The majority of respondents (62.8%) had not been trained on infection prevention and control since the outbreak of the pandemic. Only 95 (23.2%) had seen COVID-19 Standard Operating Procedures (SOP) displayed in the hospital. The use of the personal protective equipment (PPE) kit comprising the N-95 mask, face shield, gown, and shoes was seen by 194 (47.4%) respondents in recent times. A total of 397 (97.0%) respondents felt they were at an increased risk of contracting COVID-19 relative to the general populace. Measures taken to prevent COVID-19 included: wearing of face mask (68.7%), hand gloves (78.2%), frequent use of hand sanitizers (84.1%), frequent hand washing (84.8%), the daily wash of uniforms and ward coats (44.5%), daily cleaning of footwear (31.7%), and avoidance of taking home clothing and footwear worn in the hospital (54.2%)., Conclusion: Despite having good knowledge of transmission and clinical features of SARS-CoV 2, the utilization of protective measures by HCW in this study is unsatisfactory., Competing Interests: None

The aetiologic agent of COVID-19 is a novel coronavirus, SARS-CoV-2. Like other coronaviruses, it generally induces enteric and respiratory diseases in animals and humans. COVID-19 may be subclinical, and symptomatic, ranging from mild-to-severe disease. The spectrum of presentation is the result of several factors ranging from the inoculum size, inherent host susceptibility, possible cross-reacting circulating antibodies. Subclinical viral infections are associated with widespread community transmission and in some cases like Polio, herd immunity. An understanding of the biology and immune behavior in subclinical coronavirus disease 2019 (COVID-19) might be useful in the quest for vaccine development as well as the current control efforts against the COVID-19 pandemic. We carried out a narrative review of the available literature on the biology, etiopathogenesis, clinical manifestation of SARS-CoV-2 viral infection, focusing on our current understanding of the disease mechanisms and its clinical manifestation, and the host immune response to the infection. We also highlighted some of the research gaps regarding subclinical infection in COVID-19 and its potential application for vaccine development and other preventive efforts toward containing the current COVID-19 pandemic., Competing Interests: Conflicts of interest There are no conflicts of interest.

Background: Hypertension is one of the commonest cause of chronic kidney disease (CKD) in Nigerians. We describe blood pressure (BP) control and kidney disease markers in patients with hypertension as part of measures to curb the burden of this chronic debilitating disease., Methods: Patients with hypertension in the main tertiary hospitals in three states in north central Nigeria were evaluated for indicators of CKD, including proteinuria and estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m 2 . Patients had their early morning first void urine tested for proteinuria using Combi-10 test strips. eGFR was estimated using the MDRD equation., Results: A total of 1063 subjects (63.1% females and 36.8% males) with a mean age of 55 ± 11 years were studied. Diabetes mellitus (DM) was present in 214 (20.6%) and 422 (39.7%) had optimal BP control. The median duration of hypertension was 6 years (range 1-44 years). Proteinuria occurred in 130 (12.2%), while 212 (19.9%) had reduced eGFR and 46 (4.3%) had proteinuria and reduced eGFR. The use of calcium channel blockers [adjusted odds ratio (AOR): 0.70, 95% Confidence Interval (CI) 0.50-0.99] and the use of more than two antihypertensive medications (AOR: 0.62, 95% CI 0.40-0.96) were associated with reduced odds of optimal BP control. Male sex (AOR: 1.75, 95% CI 1.14-2.70) and the use of renin-angiotensin-aldosterone system blocking medications (AOR: 2.07, 95% CI 1.18-3.64) were independently associated with proteinuria while DM (AOR: 1.69, 95% CI 1.06-2.55) and treatment with more than two medications (AOR: 1.86, 95% CI 1.09-3.17) were more likely to have reduced eGFR., Conclusion: A large proportion of hypertensive patients in north-central Nigeria have poorly controlled BP. Kidney damage is common among these patients., Competing Interests: None

Objectives and Method: There are growing concerns of tenofovir disoproxil fumarate (TDF)-associated renal toxicity. We evaluated the effect of long-term TDF exposure on renal function in a cohort of HIV-1-infected Nigerians between 2006 and 2015. Multivariate logistic regression was used to identify predictors of renal impairment at different time over 144 weeks of antiretroviral therapy (ART)., Results: Data of 4897 patients, median age 42 years (interquartile range: 36-49), and 61% females were analyzed. The prevalence of renal impairment increased from 10% at week 24 to 45% at 144 weeks in TDF-exposed participants compared to an increase from 8% at 24 weeks to 14% at 144 weeks in TDF-unexposed participants. Tenofovir disoproxil fumarate exposure predicted the risk of renal impairment at 144 weeks of ART (odds ratio: 2.36; 95% confidence interval: 1.28-4.34)., Conclusion: Long-term exposure to TDF-based ART significantly increases the likelihood of renal impairment. The continued use of TDF-based regimen in our setting should be reviewed. We recommend the urgent introduction of tenofovir alafenamide-based regimen in the HIV treatment guidelines of Nigeria and other resource-limited countries.

Backround: Secondary hyperparathyroidism (SHPT) is a manifestation of chronic kidney disease mineral bone disorder (CKD-MBD). SHPT is common in patients with chronic kidney disease (CKD) and is associated with significant morbidity and mortality., Methods: A cross- sectional descriptive study involving 230 patients with CKD., Results: The mean age of the study population was 44.17±15.24 years. The median intact parathyroid hormone and alkaline phosphatase levels were 96pg/ml (range 4-953pg/ml) and 88 iu/l (range 10-800 iu/l) respectively. The mean (with standard deviation) calcium, serum phosphate, calcium phosphate product and haemoglobin levels were 2.22±0.29mmol/l, 1.8±0.62mmol/l, 3.94±1.42mmol 2 /l 2 and 9.90±1.87g/dl respectively. Majority of patients had advanced CKD with 70.3% of patients in stage G5. The prevalence rates of SHPT, hypocalcaemia, hyperphosphataemia, elevated alkaline phosphatase and elevated calcium phosphate product were 55.2%, 34.8%, 66.1%, 42.2% and 25.2% respectively.Univariate analysis revealed that SHPT was associated with hypocalcaemia, hyperphosphataemia, elevated alkaline phosphatase, proteinuria, anaemia, hypertension, left ventricular hypertrophy and stage of kidney disease; being worse with advancing kidney disease. Independently associated with SHPT were hypocalcaemia (OR=4.84), hyperphosphataemia (OR=3.06), and elevated alkaline phosphatase (OR=2.04)., Conclusion: The prevalence of SHPT in CKD is high, occurs early and is independently associated with hypocalcaemia, hyperphosphataemia and elevated alkaline phosphatase. The prevalence of SHPT also increases with worsening renal function.

Background: Hemodialysis (HD) is the main form of renal replacement therapy available in Nigeria. However, this is still largely unaffordable by individuals with resultant poor outcomes., Methods: This was a retrospective study of all patients with renal failure who had dialysis in the renal unit of Dalhatu Araf Specialist Hospital over the past 2 years. Information retrieved included sex, age, cause of renal failure, human immunodeficiency virus status, hepatitis B surface antigen status, antibodies to hepatitis C virus status, number of sessions, total duration on dialysis (in weeks), use of erythropoietin (EPO), common problems encountered on the dialysis machine, and the outcome of the patient., Results: A total of 68 patients (50% males) were enrolled in the study. The mean age was 41 ± 15 years (17-75), and mean weight in kilograms was 64.3 ± 10.9 (42-87). Acute kidney injury was seen in 18 (26.5%), while 50 (73.5%) had end-stage renal disease (ESRD). Chronic glomerulonephritis was the leading cause of ESRD (46%) with autosomal dominant polycystic kidney disease being the least (2%). The mean packed cell volume at the start of dialysis was 25.7% ± 5.9%. Tunneled necklines were in 11 (16.8%) and femoral catheters were in 48 (70.6%). The median total number of sessions was 4.0 (1-136), while the median duration on dialysis was 1 week (1-48) with both sexes having the same duration on dialysis ( P = 0.44). The average frequency of dialysis among those with ESRD was twice weekly. Only 15 (30.0%) of those with ESRD continued dialysis after 3 months. The median survival time for females was 5 weeks while that for the males was 20 weeks ( P = 0.108). EPO use was in 12 (17.7%) being 4000 IU once weekly. Cramps complicated the first sessions of dialysis in 27 (39.7%) patients., Conclusion: The survival of patients on HD in our environment is poor due largely to poor affordability despite its availability., Competing Interests: There are no conflicts of interest.
