    ABSTRACT: The objective of this observational study was to quantify the incidence of urinary tract infections (UTI) among diabetes patients and compare this risk to patients without diabetes. Type 2 diabetes patients and a matched sample of patients without diabetes were identified from GPRD. Patients were followed for 1-year from their study index date until the first record of a UTI or a censored event. The incidence of UTI was 46.9 per 1000 person-years (95% confidence interval (CI) 45.8-48.1) among diabetes patients and 29.9 (95% CI 28.9-30.8) for patients without diabetes. Compared to the non-diabetes patients, the risk of UTI was 1.53 (95% CI 1.46-1.59) for all diabetes patients; and 2.08 (95% CI 1.93-2.24) for patients with previously diagnosed diabetes. In general practice, across gender and age, the risk of developing a UTI is higher for patients with type 2 diabetes compared to patients without diabetes.

    ABSTRACT: The objective of this population-based study was to evaluate the incidence of vaginitis (females) and balanitis (males) among a cohort of type 2 diabetes patients and compare this risk to patients without diabetes. The study population included 125,237 female patients and 146,603 males identified from GPRD. All patients were followed for 1-year from their study index date for the first record of an infection or a censored event. Among patients with diabetes the incidence of vaginitis was 21.0/1000PY (95% CI 19.8-22.1) with the risk being 1.81 (95% CI 1.64-2.00) greater that patients without diabetes. The incidence of balanitis among diabetes patients was 8.4/1000PY (95% CI 7.8-9.1) with a relative risk of 2.85 (2.39-3.39) compared to patients without diabetes. Additional analyses were performed by HbA1c level. Results from this large population-based study indicate that patients with diabetes are at an increased risk of being diagnosed with infections of the genital tract and patients with poorly controlled diabetes have higher risks.
