RESUMO
INTRODUCTION: Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in the chronic kidney disease (CKD) population. CKD patients are more likely to die from CVD before ever reaching end-stage renal disease (ESRD). The study, therefore, seeks to identify the prevalence of risk factors of CVD in CKD patients such as systemic hypertension, anemia, dyslipidemia, hypoalbuminemia, albuminuria, and abnormal calcium/phosphate products. METHODS: The study was a case-control cross-sectional study where one hundred fifty hypertensive CKD patients and age- and sex-matched hypertensive non-CKD subjects were consecutively enrolled at the renal unit of Delta State University Teaching Hospital (DELSUTH), Oghara. RESULTS: The findings of the study revealed the mean ages of cases and controls to be 48.91±11.93 years and 51.0±15.45 years respectively (p-value 0.182). There was an equal number of males and females among the study group and controls (92 males and 58 females) making a male-to-female ratio of 3:2. The prevalence of CVD risk factors such as diabetes mellitus, hypercholesterolemia, hypertriglyceridemia, elevated low-density lipoprotein, anemia, hypocalcemia, hyperphosphatemia, albuminuria, and hypoalbuminemia was significantly higher among the CKD group compared to controls. Similarly, the prevalence of reduced high-density lipoprotein (HDL) was higher among cases than controls, the difference was however not statistically significant. CONCLUSION: The study has shown that systemic hypertension, diabetes, anemia, dyslipidemia, hypoalbuminemia, albuminuria, and abnormal calcium/phosphate products increases the risk for CVD in the general population but is more expressed and significant in CKD patients.
RESUMO
In Nigeria, there is paucity of data on malnutrition among chronic kidney disease (CKD) patients especially before the initiation of dialysis therapy, necessitating this study. The study subjects consisted of 96 CKD patients recruited from the renal unit of our hospital. Forty age-and sex-matched controls were also studied. Nutritional status was assessed using Subjective Global Assessment (SGA), weight change over six months of follow-up, body mass index, mid-upper arm circumference, triceps skinfold thickness, and serum albumin concentration. A three-day food diary was used to determine the average daily protein intake of the patients. Sixty-six CKD patients completed the study. The age range of CKD patients was 23-65 years with a mean of 47.1 ± 13.2 years while the age range of the controls was 23-65 years with a mean of 44.1 ± 14.3 years. Out of the 66 CKD patients studied, four lost >10% of their body weight. The body mass index (BMI) was low (<20 kg/m2) in eight (12.1%) of CKD patients, while three (7.5%) subjects in the control population had BMI of <20 kg/m2. The serum albumin was less than 3 g/dL in seven (10.6%) of the CKD patients, SGA identified malnutrition in 30 (46%) of the CKD patients. The prevalence of malnutrition in predialysis CKD patients was high in this study.
