Kidneys functions in older adults with diabetic and hypertension problems

Abstract

Introduction: the decrease in glomerular filtration rate in older adults’ patients with diabetic and hypertensive problems is a consequence of physiological factors to which are added some vascular changes associated with alterations produced by underlying chronic diseases. Objective: to characterize renal function in older adults’ patients with diabetic and hypertensive problems attended at the Family Doctor's Office No. 4, Policlínico Docente "Ángel Alfonso Ortiz Vázquez", Manzanillo, Granma. Method: a descriptive, retrospective study was carried out in 2020 to determine the renal function in 249 older adults with diabetic and hypertension problems. The Cockcroft-Gaulty formula was used. The following variables extracted from the medical records were used: diagnosis of diabetes mellitus, diagnosis of hypertension, age, sex, weight and creatinine text. Results: male sex predominated (52.2 %). The mean age range, between 60 and 87 years, was 68.9 ± 7.3. The minimum glomerular filtration rate was 27.5 ml/min/1.73 m2, and the maximum was 143.7 ml/min/1.73 m2, the mean rate in these patients was 69.2 ± 18.7 ml/min/1.73 m2. For male was 71.4 ± 19.0 ml/min/1.73 m2 and 66.8 ± 18.2 ml/min/1.73 m2 for female. Hypertension predominated (94.4%) over diabetes mellitus (41.8%). The glomerular filtration rate in hypertensive patients (29.7 %) was less than 60 ml/min/1.73 m2. Conclusions: a third of patients with diabetic and hypertension had decreased in glomerular filtration rate, and this decrease was associated with increasing age.
