Asymptomatic bacteriuria may be considered a complication in women with diabetes

WSTĘP. Celem pracy jest ocena częstości występowania oraz czynników ryzyka bezobjawowej bakteriurii (ASB, asymptomatic bacteriuria) u kobiet bez cukrzycy i chorych na cukrzycę. MATERIAŁ I METODY. Do badania włączono 636 kobiet chorych na cukrzycę (typu 1 i 2) w wieku 18&#8211;75 lat, które w tym czasie nie były w ciąży i nie występowały u nich zaburzenia układu moczowego, oraz 153 kobiety bez cukrzycy, które zgłosiły się do okulisty lub do lekarza innej specjalności w celu leczenia urazów (jako grupa kontrolna). Bezobjawową bakteriurę zdefiniowano jako obecność co najmniej 105 bakterii na ml jednego lub dwóch rodzajów tworzących kolonie, wyhodowanych z czystego, środkowego strumienia moczu osoby bez objawów zakażenia dróg moczowych (UTI, urinary tract infection). WYNIKI. Bezobjawowa bakteriuria występowała u 26% kobiet chorych na cukrzycę i u 6% kobiet bez cukrzycy (p < 0,001). Częstość ASB u kobiet chorych na cukrzycę typu 1 wyniosła 21%. Czynniki ryzyka ASB w cukrzycy typu 1 to: dłuższy czas trwania choroby, neuropatia obwodowa i makroalbuminuria. U kobiet chorych na cukrzycę typu 2 ASB występowała w 29% przypadków. Czynniki ryzyka ASB w cukrzycy typu 2 to: wiek, makroalbuminuria, niższy wskaźnik BMI oraz przebyte w poprzednim roku zakażenie dróg moczowych. Nie stwierdzono związku między aktualnym poziomem HbA1c i obecnością ASB. WNIOSKI. Częstość ASB jest większa u kobiet chorych na cukrzycę niż bez cukrzycy i schorzenie to można uznać za jedno z powikłań cukrzycy u kobiet.OBJECTIVE. To study the prevalence of and risk factors for asymptomatic bacteriuria (ASB) in women with and without diabetes. RESEARCH DESIGN AND METHODS. A total of 636 nonpregnant women with diabetes (type 1 and type 2) who were 18&#150;75 years of age and had no abnormalities of the urinary tract, and 153 women without diabetes who were visiting the eye and trauma outpatient clinic (control subjects) were included. We defined ASB as the presence of at least 105 colony-forming units/ml of 1 or 2 bacterial species in a culture of clean-voided midstream urine from an individual without symptoms of a urinary tract infection (UTI). RESULTS. The prevalence of ASB was 26% in the diabetic women and 6% in the control subjects (P < 0.001). The prevalence of ASB in women with type 1 diabetes was 21%. Risk factors for ASB in type 1 diabetic women included a longer duration of diabetes, peripheral neuropathy, and macroalbuminuria. The prevalence of ASB was 29% in women with type 2 diabetes. Risk factors for ASB in type 2 diabetic women included age, macroalbuminuria, a lower BMI, and a UTI during the previous year. No association was evident between current HbA1c level and the presence of ASB. CONCLUSIONS. The prevalence of ASB is increased in women with diabetes and might be added to the list of diabetic complications in these women

Acuut delier, waarschijnlijk uitgelokt door claritromycine

Clarithromycin is a relatively new antibiotic with many applications. Its frequent use explains why side-effects previously reported seldom now become clear. Two patients, a man aged 74 and a woman aged 56 years, developed delirium after treatment with clarithromycin as part of eradication treatment of Helicobacter pylori, presumably as a result of an ideosyncratic reaction to the clarithromycin. Preclinical and clinical investigations did not reveal side effects on the central nervous system. By now the appearance of a delirium presumably related to the use of clarithromycin has been described in several patients. Furthermore some patients had a positive rechallenge. Finally, 17 reports on psychiatric side effects, of which 7 were delirium, after the use of clarithromycin reached the Netherlands Pharmacovigilance Foundation (Lareb). This combination of facts makes a causal relationship probable

Lowering blood glucose during hip surgery does not influence coagulation activation

Background: Hyperglycaemia during and after hip surgery is associated with coagulation activation and an increased risk of venous thromboembolism. Whether lowering of glucose levels during hip surgery diminishes coagulation activation is unknown. We investigated the efficacy of the human GLP-1 analogue liraglutide to lower glucose during and after hip surgery and studied its influence on coagulation activation. Methods: A total of 37 obese subjects who underwent hip surgery were randomized to subcutaneous liraglutide or placebo for 4 consecutive days, starting one day prior to surgery. Glucose levels and coagulation indices at three fixed time-points (pre-operative, 2 h post-operative and 3 days post-operative) were measured. Results: Liraglutide reduced glucose at day three post-surgery (median glucose (IQR) liraglutide 5.5 (5.2–5.7) vs. placebo 5.8 (5.5–6.2); difference 0.3 mmol/L, P = 0.04). Changes in 6 out of 8 coagulation indices studied did not differ between the two groups. Only D-dimer levels were significantly lower in the liraglutide group at day three post-surgery and FVIII levels were significantly higher in the liraglutide group 2 h post-surgery. Conclusion: Although the human GLP-1 analogue liraglutide moderately reduced post-operative blood glucose levels in non-diabetic and prediabetic obese patients undergoing elective hip surgery, no changes were observed with respect to coagulation activation

Exercise in Closed-Loop Control: A Major Hurdle

Background: People with type 1 diabetes mellitus (T1DM) are at risk for exercise-induced hypoglycemia. Prevention of such hypoglycemia in a closed-loop setting is a major challenge. Markers for automated detection of physical activity could be heart rate (HR) and body acceleration counts (AC). Correlations between HR, AC, and glucose concentrations before and after moderate intensity exercise were examined in T1DM patients during open-loop control. Method: Eleven T1DM subjects treated with an insulin pump performed moderate intensity exercise of 30 min. Glucose profiles, insulin concentrations, HR, and acceleration were measured. Results: Mean (range) glucose decrease during exercise was 1.4 (0 to 3.3) mmol/liter. The mean increase in HR was 45.2 beats per minutes (15 to 106 bpm). Mean increase in AC was 18,000 (3,000 to 25,000). No correlations were seen between the glucose drop and HR or AC. A trend was observed between the increase in HR and increase in AC. Conclusion: Moderate intensity exercise resulted in increased HR and body AC while it decreased glucose concentrations but, in this real-time setting, no association could be demonstrated between the glucose decrease and increase in HR or AC.
