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.

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.

Background: Studies indicate a prevalence of 39.2% diabetes mellitus (DM) as the most common underlying cause in patients with dialysis. Statistics showed that the rates of morbidity and mortality were higher in hemodialysis patients with diabetes compared with hemodialysis patients without diabetes. The aim of this study was to evaluate the risk factors responsible for infections in patient’s chronic renal failure on hemodialysis patients having diabetic foot ulcers.
Methods: In this cross-sectional study, data were collected from 30 randomly selected hemodialysis patients who were referred to Imam Reza hospital, Tabriz from April 2016 to April 2017. The patients' records were taken according to inclusion and exclusion criteria and data were collected in designed questionnaires for further analysis.
Results: 63.3% of patients were males and 36.7% were females. The average age of study population was 51.23±12.74. Duration of dialysis was 5.15±3.58 years. The average HBA1C was 9.08±1.48. Bacterial cause of feet ulcer was isolated only in 56.7% of cases. Isolated bacteria were anaerobic (47.05%), gram-positive (35.29%) and gram negative (17.64%). Amputation was performed in 26.7% of cases. Mortality was reported in 13.3% of patients. Low personal hygiene, presence of vasculopathy, mortality and amputation was higher in anaerobic infections. Most infections were seen in patients with inadequate dialysis. Low dialysis adequacy, amputation, vasculopathy, increased duration of dialysis, poor hygiene was seen in patients with higher HbA1C.
Conclusion: These results indicate the importance of diabetic foot ulcers caused by anaerobic infections, because of the outcome of amputation and higher mortality rates in these patients, the prognosis is worse than other cases. Also, due to the direct relationship between personal hygiene and the development of anaerobic infections, it is possible to prevent these infections significantly by following these considerations. Most infections were found to be inappropriate in dialysis adequately. Therefore, accurate monitoring of patient's diabetes in the long run and the importance of this can control the complications of diabetes, including vasculopathy, followed by the need for amputation for fighting against diabetic foot ulcers.
