RESUMO
BACKGROUND: The burden of chronic kidney disease (CKD) in Nigeria is quite alarming. The prevalence of CKD ranges from 11 - 23.5%. Hypertension and chronic glomerulonephritis (CGN) remain the two leading causes of CKD in Nigeria. The etiology of CKD in many of these patients remains unknown, as few biopsies are done. In order to demystify the various glomerular diseases that culminate in CGN, performing a kidney biopsy offers a ray of hope. Few studies on renal biopsies have emanated from Nigeria; this study, however, is unique as the histopathological analysis involves light, immunofluorescence, and electron microscopies. METHODS: This study involved two teaching hospitals in Lagos. Patients from these centers, who met the inclusion criteria, underwent real-time renal biopsy; after providing written informed consent. RESULTS: Among the 52 patients analyzed 26, (50%) were males. The mean age was 31.7 ± 12.8, with age range of 13 - 56 years. The most common indication for kidney biopsy was nephrotic syndrome, accounting for 73%. Focal segmental glomerulosclerosis (FSGS) was the most frequent histopathological diagnosis seen in 25 patients (48.1%). CONCLUSION: The findings from this study highlight the role that renal biopsy plays in making a concrete diagnosis in nephrology practice in a developing country like Nigeria. As almost 80% of the study population was made up of patients with FSGS and lupus nephritis, it remains to be determined by further studies among our patients, the role that Apolipoprotein L1 (APOL 1) gene mutation will play in the etiology of renal diseases in Nigeria.

Background: Periodontal diseases are chronic and inflammatory in nature, and have been associated with hypertension, a major risk factor for cardiovascular diseases. Hypertension is prevalent among Nigerians. However, controlled studies on the relationship between hypertension and periodontal disease in Nigeria are limited. Here, we investigated the relationship between periodontal diseases and hypertension among Nigerians. Methodology: This comparative, cross-sectional study assessed the periodontal clinical parameters, and body mass index (BMI) of 75 hypertensives and 75 gender-matched normotensive controls in a teaching hospital in Lagos, Nigeria. Hypertension was categorized as blood pressure ≥140/90 mm Hg based on the WHO guidelines. Sociodemography, periodontal parameters, BMI, and blood pressure were documented in interviewer-administered questionnaires. Periodontal disease was assessed by the highest Community Periodontal Index (CPI) scores, CPI sextants, gingival index (GI), simplified oral hygiene index (OHIS), and number of teeth with gingival recession. Hypertension was the dependent variable, while periodontal disease, obesity, age were the independent variables. P values <0.05 were considered statistically significant. Results: The mean CPI 3 sextant was significantly associated with hypertension (P<0.05). The independent predictors of hypertension were moderate gingival inflammation (OR 3.314, 95% CI 1.156-9.502, p=0.026), older age >60 years (OR 11.527, 95%CI 2.976-44.651, P<0.001), overweight/obesity (OR 3.279, 95%CI 1.414-7.602, P=0.006), and lower education (OR 3.070, 95% CI 1.288-7.319, P=0.011). Conclusion: In addition to the known risk factors for hypertension, moderate gingivitis was a predictor of hypertension, while hypertensives had a greater extent of pockets than non-hypertensives. This study reiterates the association of preventable, low-grade periodontal inflammation with hypertension.
RESUMO
Despite positive economic forecasts, stable democracies, and reduced regional conflicts since the turn of the century, Africa continues to be afflicted by poverty, poor infrastructure, and a massive burden of communicable diseases such as HIV, malaria, tuberculosis, and diarrheal illnesses. With the rising prevalence of chronic kidney disease and kidney failure worldwide, these factors continue to hinder the ability to provide kidney care for millions of people on the continent. The International Society of Nephrology Global Kidney Health Atlas project was established to assess the global burden of kidney disease and measure global capacity for kidney replacement therapy (dialysis and kidney transplantation). The aim of this second iteration of the International Society of Nephrology Global Kidney Health Atlas was to evaluate the availability, accessibility, affordability, and quality of kidney care worldwide. We identified several gaps regarding kidney care in Africa, chief of which are (i) severe workforce limitations, especially in terms of the number of nephrologists; (ii) low government funding for kidney care; (iii) limited availability, accessibility, reporting, and quality of provided kidney replacement therapy; and (iv) weak national strategies and advocacy for kidney disease. We also identified that within Africa, the availability and accessibility to kidney replacement therapy vary significantly, with North African countries faring far better than sub-Sahara African countries. The evidence suggests an urgent need to increase the workforce and government funding for kidney care, collect adequate information on the burden of kidney disease from African countries, and develop and implement strategies to enhance disease prevention and control across the continent.
RESUMO
BACKGROUND: The burden of symptoms and other concerns in chronic kidney disease (CKD) is known to be high, adversely affecting the quality of life of the growing number of those with this condition in developing countries. In this paper, we describe the protocol of a longitudinal observational study among people living with CKD. The study is developed to assess the bio-psychosocial factors associated with palliative care symptoms and concerns, and pattern of health services usage among Nigerians with stages 3-5 CKD. The overall objective is to establish the evidence-base for advocacy and policy formulation, treatment guidelines, care and services, and future clinical trial studies. METHODS: This is a multi-center study to investigate the longitudinal course of symptoms and other concerns among patients with stages 3-5 CKD in Nigeria. Interviewer administered and self-report measures at baseline (T0) and 3-month (T1) address socio-demographic characteristics, clinical-illness related information, palliative care-related symptoms and other concerns, pattern of formal or informal service usage, and bio psychosocial measures including estimated glomerular filtration rate (eGFR), anxiety, depression, quality of life, functioning, social support and spiritual wellbeing. DISCUSSION: This study represents the first longitudinal investigation of palliative care symptoms and concerns among people with CKD in Nigeria. It includes early stages of CKD in compliance with best practices, and a comprehensive range of bio-psychosocial outcomes to understand how these factors are associated with symptoms. This study will provide evidence for how best to integrate palliative care into management of CKD to improve care and quality of life of people with CKD. The study team welcomes collaborations with both national and international researchers.

BACKGROUND: Long-term treatment of common chronic cardiac conditions such as hypertension with calcium channel blockers (CCBs) has long been associated with gingival hyperplasia. This oral side effect may affect esthetics and function, yet often overlooked and therefore underreported among Nigerians. AIM: This study aimed to determine the association of CCBs with gingival overgrowth (GO) in hypertensive patients. METHODS: This was a hospital-based, case-control study conducted among 116 hypertensive patients (58 CCB and 58 non-CCB age-matched controls) attending the medical outpatient clinic of a tertiary health institution in Lagos, Nigeria. Data collection tools included interviewer-administered questionnaires and periodontal examination. Sociodemographic details, medical history, and periodontal indices (gingival index, plaque index, class of GO according to drug-induced GO [DIGO] Clinical Index) were recorded. RESULTS: The mean age was 59.4 ± 12.6 years, females representing 50.9%. In the CCB group, 39 (67.2%) participants were on amlodipine and 19 (32.8%) were on nifedipine. The mean duration of CCB use was 55.6 ± 53 months. DIGO was higher in CCB (36.2%) than that in non-CCB participants (17.2%) (χ2 = 4.4, P = 0.036). The risk of GO was higher in CCB users (odds ratio [OR] 2.7, [95% confidence interval (CI)]: 1.1-6.5). Amlodipine users had higher DIGO (37.5%) than that of nifedipine users (21.1%) (OR 2.3, [95% CI]: 1.0-5.3). The predominant class of DIGO among the CCB users was Class 2 DIGO Clinical Index (90.5%). CONCLUSION: The study reveals that the risk of GO is nearly three times in CCB than that of non-CCB users and twice higher in amlodipine than nifedipine users in Nigeria.
