INTRODUCTION Diabetes mellitus and the postmenopausal period are associated with increased risk of urinary tract infections (UTIs) in women. However, data on UTIs in postmenopausal diabetic women are scarce. OBJECTIVES The aim of this study was to determine the prevalence of UTIs in postmenopausal women with type 2 diabetes mellitus, identify the potential risk factors, describe the causative pathogens, and assess their susceptibility to quinolones.  PATIENTS AND METHODS Patients were interviewed, examined, and had their hospital records analyzed. An uncontaminated midstream urine sample was collected and cultured in selective or enriched media. Colony‑forming units were counted and susceptibility to quinolones was assessed. Univariate and multivariate logistic regression models were built.  RESULTS Forty women were included in this prospective cross‑sectional study; their median age was 64 years (range, 52-84 years). UTIs occurred in 37.5% of the patients. The major implicated pathogens were Escherichia coli (66.7%) and enterococci (20%; most often Enterococcus faecalis). Most of the pathogens (93.8%) were susceptible to all tested quinolones. Patients with UTIs had a significantly lower glomerular filtration rate (P = 0.008) and higher comorbidity index (P = 0.01) compared with patients with sterile urine. Microangiopathic complications, including retinopathy and nephropathy, were identified as independent risk factor for UTIs (adjusted odds ratio, 3.5; 95% CI, 1.2-5.5; P = 0.006). The other clinical correlates of UTIs were urinary incontinence, hyperlipidemia, and microalbuminuria. CONCLUSIONS Postmenopausal diabetic patients with microangiopathy are at high risk of UTIs and therefore should be educated and vigilantly monitored. Attention should also be paid to urinary incontinence, hyperlipidemia, and microalbuminuria as other risk factors for UTIs. Quinolones are an attractive treatment option in this group of patients in Poland.

INTRODUCTION    There is an inverse relationship between high‑density lipoprotein cholesterol (HDL-C) levels and the risk of atherosclerosis. OBJECTIVES    The aim of the present study was to assess the oxidant-antioxidant balance in elderly people with different concentrations of HDL-C. PATIENTS AND METHODS    A total of 541 people aged 60 years or older were examined, of whom 90 individuals with no acute or severe chronic disorders had their waist circumference, body mass index, percentage of body fat, and blood pressure measured. Fasting and 120‑minute glycemia was determined in an oral glucose tolerance test, following which 15 patients with type 2 diabetes were excluded. Fasting plasma levels of lipids, total antioxidant status, and thiobarbituric acid-reacting substances (TBARS), as well ast the activity of erythrocyte superoxide dismutase 1 (SOD‑1) were assessed. Based on HDL-C levels, participants were divided into the high HDL‑C group (≥40.0 mg/dl and ≥50.0 mg/dl for men and women, respectively; n = 50) and the low HDL‑C group (<40.0 mg/dl and <50.0 mg/dl for men and women, respectively; n = 25). RESULTS    The groups did not differ in terms of age, blood pressure, body mass index, percentage of body fat, and glucose concentration. The high HDL‑C group had lower waist circumference (P <0.02) and lower triglyceride concentrations (P <0.00001). Increased TBARS levels (P <0.0005) was observed in the low HDL‑C group. There were no differences in SOD‑1 activity and total antioxidant status between the groups. CONCLUSIONS    HDL-C levels, which are known to reflect the antiatherogenic activity of HDL, including antioxidant properties, may indicate increasing oxidative stress in healthy elderly individuals.

The aim of this study was to assess the influence of 3 hypotensive drugs on the metabolic disorders: dyslipidemia, insulin resistance, hyperuricemia. There were 39 patients aged 20-55, with mild-to-moderate essential hypertension. The patients with other serious diseases or treated earlier with cholesterol or uric acid lowering drugs were excluded. Patients were divided into 3 groups, each was treated during 8 weeks with one drug: gr 1--trandolapril (T), gr 2--felodipine ER (F), gr 3--rilmenidine (R). Glucose and insulin in oral glucose tolerance test, I/G proportion, serum lipids and uric acid were tested before and after therapy. The therapy did not influence lipid parameters: LDL, HDL, triglyceride. In the T group there could be observed a significant reduction of total cholesterol value. Examined drugs did not induce changes in serum carbohydrate. The significant reduction of serum uric acid could be observed only after F therapy. Analysed drugs are very useful in therapy of hypertension with metabolic disorders.

The aim of this study was to evaluate the influence of blood pressure variability and circadian rhythm on left ventricular mass and urinary albumin excretion rate (UAE) in patients with essential hypertension. 82 untreated patients (35 women and 47 men; mean age 41.1 +/- 13.7) were recruited to this study. Mean office blood pressure at entry was 152/97 mmHg. Ambulatory blood pressure monitoring (ABPM) was performed using an Medilog ABP recorder (Oxford). Blood pressure variability was estimated as the standard deviation (SD) of systolic and diastolic ambulatory blood pressure. Urinary albumin excretion (UAE) was estimated by the radioimmunoassay during two separate days. Echocardiography was used to measure left ventricular mass and left ventricular mass index (LVMI). The median urinary albumin excretion for the whole group was 8.2 mg/day; in 18 patients (21.9%) microalbuminuria was present. Left ventricular mass index in a whole group was 109.1 g/m2; in 23 subjects (28.0%) left ventricular hypertrophy (LVH) was found. Patients with microalbuminuria as well as with left ventricular hypertrophy had higher office and 24 hour ambulatory systolic and diastolic blood pressure and higher systolic blood pressure variability. During ABPM 18 patients with absent nocturnal fall in blood pressure (non-dippers) were found; they did not display more frequent prevalence of target organ damage. Increased 24-hour blood pressure variability present in hypertensive subjects with both microalbuminuria and left ventricular hypertrophy may suggest that this phenomenon plays role in development of target organ damage.
