Correlation between chronic hypertension and occurrence of urinary tract infection

Abstract

Background: Urinary tract infections are very common in patients with high blood pressure. Hypertensive patients experience an average of three times of urinary tract infection per year. Blood pressure control is very important for preventing complications and also for identifying high-risk groups. Since, there is no national related study in this regard, the present study was conducted to investigate the effect of chronic hypertension on the incidence and recurrence of urinary tract infections. Methods: In this case-control study, the required data were collected from outpatient cases referring to Taleghani Hospital and Sina Hospital related to Tabriz University of Medical Sciences in Tabriz city, Iran. Data needed for the control group included patients accompanying patients who had no symptoms of urinary tract infection and with no history of blood pressure. Results: 60 patients with urinary tract infections were examined: 57 (47.5%) of the subjects were men and 63 (52.5%) women. There was a significant relationship between the rate of red blood cell deposition in the first hour and systolic blood pressure. There was no significant correlation between the numerical value of white blood cell count and systolic or diastolic blood pressure in the studied patients. Conclusion: According to the results of the present study, there was a significant difference in systolic blood pressure in patients ESR 1 hour (red blood cell deposition rate in the first hour) with hypertension in case and control groups. There was a significant correlation between the ESR of the first hour and systolic blood pressure in the study, so that with an increase in ESR 1h, the systolic blood pressure increased in the examined patients, however, no significant correlation was found between ESR 1hour and diastolic blood pressure. Also, there was no meaningful correlation between the numerical value of white blood cell count and systolic or diastolic blood pressure in the studied patients. There was no significant correlation between systolic and diastolic blood pressure and age. é 2017, Tehran University of Medical Sciences. All rights reserved.
