Association of Periodontal Disease with Hypertension in Nigerian Patients: A Comparative Study.

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.

Trends in the epidemiology of childhood nephrotic syndrome in Africa: A systematic review.

Background: Childhood nephrotic syndrome, if left untreated, leads to progressive kidney disease or death. We quantified the prevalence of steroid-sensitive nephrotic syndrome, steroid-resistant nephrotic syndrome, and histological types as the epidemiology of nephrotic syndrome in Africa remains unknown, yet impacts outcomes. Methods: We searched MEDLINE, Embase, African Journals Online, and WHO Global Health Library for articles in any language reporting on childhood nephrotic syndrome in Africa from January 1, 1946 to July 1, 2020. Primary outcomes included steroid response, biopsy defined minimal change disease, and focal segmental glomerulosclerosis (FSGS) by both pooled and individual proportions across regions and overall. Findings: There were 81 papers from 17 countries included. Majority of 8131 children were steroid-sensitive (64% [95% CI: 63-66%]) and the remaining were steroid-resistant (34% [95% CI: 33-35%]). Of children biopsied, pathological findings were 38% [95% CI: 36-40%] minimal change, 24% [95% CI: 22-25%] FSGS, and 38% [95% CI: 36-40%] secondary causes of nephrotic syndrome. Interpretation: Few African countries reported on the prevalence of childhood nephrotic syndrome. Steroid-sensitive disease is more common than steroid-resistant disease although prevalence of steroid-resistant nephrotic syndrome is higher than reported globally. Pathology findings suggest minimal change and secondary causes are common. Scarcity of data in Africa prevents appropriate healthcare resource allocation to diagnose and treat this treatable childhood kidney disease to prevent poor health outcomes. Funding: Funding was provided by the Canadian Institute for Health Research (CIHR) and the National Institute of Health (NIH) for the H3 Africa Kidney Disease Research Network. This research was undertaken, in part, from the Canada Research Chairs program.

The burden of caring for renal patients: The nurses perspective.

Prevalence of chronic kidney disease (CKD) in Nigeria is on the increase and it is associated with increasing caregiving burden for both the professionals and informal caregivers. This study evaluated the burden experienced by nurses caring for CKD patients, identified the procedures causing the caregiving burden and factors associated with burden in two hospitals in Ondo State, Nigeria. Two hundred and forty nurses caring for renal patients were selected from two health institutions in Ondo State. Information on sociodemographic data was obtained using a self-administered questionnaire. The burden of care was evaluated using the Zarith Burden of Life Instrument (ZBI), with aggregate score ranged from 0-88. A score of 21-40 indicates mild-to-moderate burden while a score >40 indicates high burden. The mean age of the respondents was 33.7 ± 7.5 years (age range: 20-67 years). Forty percent experienced no burden, 48.3% experienced mild-to-moderate burden, 10.4% experienced severe burden while only 1.3% experienced very severe burden. Dialysis procedure (65.5%) was identified as posing the greatest caregiving burden. Factors identified as responsible for caregiving burden were shortage of staff (68%), followed by lack of funds on the part of the patients (67.1%). Caregiving burden was not associated with age, gender, or years of experience. Prevalence of caregiving burden was very high among the respondents and dialysis was identified as causing greatest burden. Government should fund and improve staffing of dialysis units to reduce caregiving burden.

Challenges of providing maintenance hemodialysis in a resource poor country: Experience from a single teaching hospital in Lagos, Southwest Nigeria.

Providing maintenance hemodialysis is associated with high costs and poor outcomes. In Nigeria, more than 90% of the population lives below the poverty line, and patients with end-stage renal disease (ESRD) pay out-of-pocket for maintenance hemodialysis. To highlight the challenges of providing maintenance hemodialysis for patients with ESRD in Nigeria, we reviewed records of all patients who joined the maintenance hemodialysis program of our dialysis unit over a 21-month period. Information regarding frequency of hemodialysis, types of vascular access for dialysis, mode of anemia treatment and frequency of blood transfusion received were retrieved. One hundred and twenty patients joined the maintenance hemodialysis program of our unit during the period under review. Seventy-two (60%) were males and the mean age of the study population was 47 + 14 years. The mean hemoglobin concentration at commencement of dialysis was 7.3 g/dL + 1.6 g/dL. The initial vascular access was femoral vein cannulation in all the patients. A total of 73.5% of the patients required blood transfusion at some point with 33% receiving five or more pints of blood. Only 3.3% of the patients had thrice weekly dialysis, 21.7% dialyzed twice weekly, 23.3% once weekly, 16.7% once in two weeks, 2.5% once in three weeks and 11.7% once monthly. At the time of review, 8.3% of the patients had died while 38.3% were lost to follow-up. Majority of patients with ESRD on maintenance hemodialysis in our unit were poorly prepared for dialysis, were under-dialyzed, and were frequently transfused with blood with resultant poor outcomes.

Adiponectin and atherosclerosis risk factors in African hemodialysis patients: a population at low risk for atherosclerotic cardiovascular disease.

Atherosclerotic cardiovascular disease (CVD) is the major cause of morbidity and mortality in hemodialysis (HD) patients. Adiponectin (ADPN), a recently discovered collagen-like protein, is secreted exclusively by adipocytes. It has anti-atherogenic properties and reduced serum ADPN levels have been shown to be predictive of cardiovascular events. In this study, we determined the atherosclerotic risk and the significance of ADPN levels in our HD patients and also examined its relationship to other traditional CVD risk factors. A cross-sectional study of 84 patients on maintenance HD (58 Blacks and 26 non-Blacks) and 63 healthy controls matched for age, sex and race (35 Blacks and 28 non-Blacks) was undertaken. Serum ADPN levels and other risk factors, including blood pressure, serum lipid, and C-reactive protein, were studied in HD patients and were compared with the controls. Carotid artery intima-media thickness and plaque occurrence was measured by B-mode ultrasonography while echocardiography was done according to American Society of Echocardiography guidelines. Serum ADPN levels were higher in the HD group compared with the control subjects (22.19 ± 0.98 mg/mL vs. 9.93 ± 0.68 mg/mL; P < 0.001). Higher ADPN levels in HD patients were associated with lower triglyceride levels. ADPN correlated positively (r = 0.49, P < 0.0001) with left ventricular mass index (LVMI) in the total study population. ADPN levels were raised in HD patients and correlated with LVMI, possibly because of the confounding effect of low glomerular filtration rate. ADPN levels were inversely related to risk factors for atherosclerosis and may provide possible targets for therapeutic interventions.

Frequency of complementary and alternative medicine utilization in hypertensive patients attending an urban tertiary care centre in Nigeria.

BACKGROUND: To study the frequency and pattern of use of complementary and alternative medicine (CAM) in patients with essential hypertension attending a tertiary hypertension clinic. METHODS: Two hundred and twenty-five consecutive hypertensive patients attending the hypertension clinic of the Lagos University Teaching Hospital over a 3-month period were interviewed. Socio-demographic data, duration of hypertension, clinic attendance, current blood pressure, and compliance to conventional medications was documented. CAM utilization was explored using both structured and open-ended questions. RESULTS: There were 90 (40%) male and 135 (60%) female patients with mean age +/- SD overall was 55.1 +/- 12.4 years. 88 (39.1%) of the respondents used CAM. Herbal products were the most commonly used CAM type. Amongst the CAM users, the most common herbal product used was garlic (69.3%). Others were native herbs (25%), ginger (23.9%), bitter leaf (Vernonia amygdalina) (9.1%), and aloe vera (4.5%). 2.5% used spiritual therapy. There was no difference in the clinical characteristics, socio-economic status, and blood pressure control of CAM users and non-users. Patients who utilized CAM had higher BMI compared with those who did not, but the difference was not statistically significant (mean BMI +/- SD of 29.1 +/- 5.6 vs 27.1 +/- 5.9 kg/m2; P = 0.05). CONCLUSION: A significant proportion of hypertensive patients attending our tertiary facility and receiving conventional treatment also use CAM therapies. Clinicians need to be aware of this practice, understand the rationale for this health-seeking behaviour, proactively enquire about their use, and counsel patients regarding the potential of some of the therapies for adverse reactions and drug interactions.
