Blood pressure control and kidney damage in hypertension: Results of a three-center cross-sectional study in North Central Nigeria.

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 m2. 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.

Undiagnosed depression among adults with diabetes mellitus in Jos.

BACKGROUND: Diabetes mellitus (DM) and depression are common chronic disease states of public health importance with huge burden and the potential to impact many aspects of life. They are said to be related though this relationship is not fully understood. The presence of depression among patients with DM is associated with poor glycemic control, complications, and poor self-care. METHOD: This was a descriptive cross-sectional study conducted at the Diabetes Clinic of the Jos University Teaching Hospital. Three hundred and ten (310) patients with diabetes mellitus were recruited consecutively. The depression module of the Mini International Neuropsychiatric Interview (M.I.N.I.) version 5.0 was used to ascertain depression among these patients. Other demographic data were obtained using a questionnaire. Blood pressure, weight, and height were also measured and the body mass index (BMI) calculated. RESULTS: One hundred and eighty four (59.35%) of the study population were females and the mean age (SD) of the study population was 54 ± 12 years. The mean age (SD) of the females was 53 ± 11 years and that of the males was 54 ± 12 years with no significant statistical difference (P = 0.35). Two hundred and forty nine (80.32%) of the study population were urban dwellers with 140 (45.16%) earning less than N500, 000 (794 USD) yearly. Current major depression was found in 35 (11.3%) patients, among whom 7 (2.3%) had recurrent depression. The presence of DM complications (OR: 3.50, 95% CI 1.16-10.61) and a positive family history of depression (OR: 4.03, 95% CI 1.32-12.29) were found to be correlates of current major depression. CONCLUSION: The prevalence of current major depression among patients with diabetes mellitus in this study is high. We recommend that all patients with DM should be screened for depression and treated appropriately to reduce its consequences.
