This study examined whether non-insulin-dependent diabetic (NIDDM) subjects have an increased prevalence of asymptomatic bacteriuria compared with subjects with normal glucose tolerance. Diabetic (n = 206) and normal (n = 418) subjects were identified from a defined geographic area in the San Luis Valley of southern Colorado. Presence of asymptomatic bacteriuria was determined by testing the subjects' urine with a reagent-strip test for nitrite and leukocyte esterase (Chemstrip LN). The ability of the Chemstrip LN to detect bacteriuria was evaluated by comparing its results with those from urine culture on a subsample of subjects. There were 7 control and 12 diabetic subjects with bacteriuria as measured by the Chemstrip LN. The prevalence of urinary tract colonization among diabetic compared with control subjects was increased 3.5-fold (95% confidence interval 1.4-8.6). Adjustment for confounding by age, sex, ethnicity, and county of residence resulted in an adjusted prevalence ratio of 4.4 (95% confidence interval 1.1-17.4). Among diabetic subjects, prevalence of bacteriuria increased with longer disease duration but was not affected by measures of glucose control. We conclude that NIDDM increases the prevalence of bacterial colonization of the urine and, therefore, probably also increases the risk of symptomatic urinary tract infection.

Women with diabetes mellitus (DM) have asymptomatic bacteriuria (ASB) and urinary tract infections (UTIs) more frequently than women without DM. For type 1 diabetes mellitus, risk factors for asymptomatic bacteriuria include a longer duration of diabetes, peripheral neuropathy and macroalbuminuria. For type 2 diabetes, the risk factors are higher age, macroalbuminuria and a recent symptomatic UTI. Poorly-controlled diabetes and residual urine after urination are no risk factors. The most important risk factor for a UTI in type 1 diabetes patients is sexual intercourse. In type 2 diabetes patients the major risk factor is the presence of asymptomatic bacteriuria. This higher prevalence does not appear to be based on a difference in virulence of the causative microorganism. Differences in host response may explain this higher prevalence: E. coli with type 1 fimbriae adhere better to uroepithelial cells in women with DM than to those in women without DM; women with DM and ASB have lower urinary cytokine concentrations and leukocyte counts compared to women without DM and ASB; in vitro studies show that E. coli grow better when glucose is present in urine. There is no consensus on whether ASB should be treated in these patients. There are indications that UTIs in diabetes patients should be treated as complicated UTIs.

We screened 228 women with diabetes for bacteriuria during the period of January 1997 through December 2000 at Pisa General Hospital (Pisa, Italy). A control group of 146 women without diabetes was also evaluated. The frequency of significant bacteriuria was 17.5% (40 of 228) among women with diabetes and 18.5% (27 of 146) among women in the control group. Seven (13.5%) of 52 and 33 (18.8%) of 176 women with type 1 and in type 2 diabetes, respectively, had significant bacteriuria. The presence of higher glycated hemoglobin levels was the only significant risk factor for significant bacteriuria in women with type 2 diabetes. A similar frequency of bacteriuria in women with and women without diabetes was found. Severe impairment of metabolic control of type 2 diabetes increases the risk of acquiring asymptomatic bacteriuria.

Most of the research about asymptomatic bacteriuria (ASB) in patients with diabetes mellitus has been performed in female patients, with a prevalence of approximately 7-13 %, about 3 to 4 times higher than that reported for nondiabetic women. Poor metabolic control, as assessed by haemoglobin A1c or glucosuria, is not associated with increased ASB. The latter is associated with an increased risk of symptomatic urinary tract infection among patients with type 2 diabetes, but not type 1 diabetes. These infections tend to be more complicated and caused by more resistant organisms than reported for nondiabetic patients. Despite this, systematic screening for and treating ASB have not been shown to reduce long-term complications, such as accelerated progression to arterial hypertension or renal failure, or symptomatic urinary tract infections (including pyelonephritis) or hospitalization for these infections. Thus, available evidence does not support systematic screening and antimicrobial treatment of ASB among patients with diabetes mellitus.

Urinary tract infection is a serious problem in diabetic patients, and asymptomatic bacteriuria (ASB) in these patients is a risk factor for pyelonephritis and renal dysfunction. In the present study, we investigated the relationships between age, body mass index, duration of diabetes, HbA1c level, glucosuria, glomerular filtration rate and microalbuminuria in type 2 diabetic patients with ASB. One hundred and twenty-three patients with type 2 diabetes mellitus were included in the study. The patients were divided into two groups according to ASB; Group I consisted of 22 patients with ASB, and Group II of 101 patients without ASB. There were no significant differences between the groups in regard to age, body mass index, creatinine clearance or microalbuminuria, while there were significant differences in HbA1c, duration of diabetes mellitus, glucosuria and pyuria (P < 0.05). The most commonly isolated microorganism was Escherichia coli. The present study identified the duration of diabetes, high HbA1c, glucosuria and pyuria as risk factors for ASB in type 2 diabetic patients.

We studied prophylactic potential of local use of estriol in respect of urinary infections (UI) in postmenopausal women with asymptomatic bacteriuria (AB) suffering from type 2 diabetes mellitus (DM). A two-stage trial has been conducted. Stage one (a prospective study) was made to detect AB in DM women with AB. Of 414 female examinees AB was detected in 87 women. At stage two these women were randomized into two groups: group 1 received 0.5 mg estriol as vaginal cream, group 2 (control) received no prophylactic treatment. After 9 months of the trial AB was detected in 19.4% women of group 1 and 68.4% of the control group (p<0.001). Clinically significant UI was detected in 8.3 and 18.4% examinees (p<0.001), respectively. No correlation was found between AB development and a HbA1c level. Estriol treatment resulted in a rise of vaginal health index (VHI), appearance of lactobacteria in the vaginal smear, lowering of atrophic vaginitis detection rate. No significant changes were registered in the controls. Thus, local estriol administration effectively prevents and treats UI in postmenopausal females.

Urinary tract infections are more common, more severe, and carry worse outcomes in patients with type 2 diabetes mellitus. They are also more often caused by resistant pathogens. Various impairments in the immune system, poor metabolic control, and incomplete bladder emptying due to autonomic neuropathy may all contribute to the enhanced risk of urinary tract infections in these patients. The new anti-diabetic sodium glucose cotransporter 2 inhibitors have not been found to significantly increase the risk of symptomatic urinary tract infections. Symptoms of urinary tract infection are similar to patients without diabetes, though some patients with diabetic neuropathy may have altered clinical signs. Treatment depends on several factors, including: presence of symptoms, severity of systemic symptoms, if infection is localized in the bladder or also involves the kidney, presence of urologic abnormalities, accompanying metabolic alterations, and renal function. There is no indication to treat diabetic patients with asymptomatic bacteriuria. Further studies are needed to improve the treatment of patients with type 2 diabetes and urinary tract infections.

Evidence shows that urine has complex bacterial profiles with considerable variation between individuals. Aging and age-related conditions can lead to the changes to the composition of urine, which means that the available nutrition for bacteria in the bladder changes with age. We explored the characteristics of the urinary microbiota of elderly women and whether these are associated with age-related conditions such as diabetes and urinary tract infections. An elderly and a non-elderly cohort of women were included. Magnetic beads were used to isolate bacterial genomic DNA, which was analyzed based on the V3-V4 hypervariable region of the 16S rRNA gene. There were significant differences between the elderly and non-elderly regarding thirteen genera of bacteria. For example, the relative abundance of Lactobacillus was dramatically reduced in the elderly compared with the non-elderly; it also decreased with age in the elderly cohort and it was not correlated with urine pH. The relative abundance of Peptococcus increased with age in the elderly while the abundance of Bifidobacteria decreased with age. The abundance of Escherichia coli was the same in the two cohorts, and it increased with water intake and was not associated with urinary tract infection events. Higher levels of Lactobacillus (including Lactobacillus iners) in the elderly were associated with diabetes, and lower levels of Peptoniphilus and Dialister were correlated with asymptomatic bacteriuria. The urinary microbiota of women is affected by ageing, type 2 diabetes mellitus and asymtomatic bacteriuria.
