ABSTRACT Background and objectives: Despite the beneficial effects of intensive insulin therapy, nephropathy continues to be a major concern in type 1 diabetes mellitus (DM). Given the scarce data on this subject in our population, we performed an observational study in order to analyse the prevalence of albuminuria and its stages in a series of patients with type 1 DM and to evaluate the related factors. Patients and methods: Cross-sectional study that included all patients aged 18 and over, diagnosed of type 1 DM for at least 6 months, consecutively attended during 2008 at the Hospital del Mar de Barcelona and Hospital Granollers. Results: 291 patients were analysed and 46 (20.2%) had micro- or macroalbuminuria. Albuminuric patients, compared to those without were older (42.0±12.3 years vs. 37.1±11.5 years), had longer duration of diabetes (22.5±11.5 years vs. 14.1±10.1 years), and higher body mass index (26.3±3.7kg/m2 vs. 25.2±3.4kg/m2), glycosylated haemoglobin (8.15±1.5% vs. 7.59±1.4%) and systolic blood pressure (139.7±21.7 mmHg vs. 122.2±20.3mmHg). Multivariate analysis showed an independent association of albuminuria with diabetes duration (OR 1.081, 95% CI 1.038-1.126), triglyceride levels (OR 1.011, 95% CI: 1.002-1.018), smoking habit (OR 3.279, CI 95%: 1.114-9.654) and hypertension (OR 3.495, 95% CI: 1.074-11.368). Conclusion: In our series, one out of five patients with type 1 DM had micro- or macroalbuminuria, and its presence is associated with diabetes duration, triglyceride concentration, smoking and hypertension.

    ABSTRACT: IntroductionThe prevalence of hypogonadotropic hypogonadism (HH) in patients with type 2 diabetes mellitus is higher than in the general population and leads to detrimental effects on metabolic control, lipid profile, and body composition. Few studies have examined its role in type 1 diabetes mellitus.AimTo determine the prevalence of HH in patients with type 1 diabetes and associated risk factors.Main Outcome MeasuresClinical and biochemical parameters were gathered on initial evaluation. An HH score creating different experimental models was devised to calculate the risk of HH for an individual with type 1 diabetes.Methods Cross-sectional study of 181 male patients with type 1 diabetes consecutively admitted to the Diabetes outpatient clinics of three urban hospitals. All participants were Caucasians aged ≥ 18 years with type 1 diabetes duration of more than 6 months.ResultsOne hundred and eighty-one male patients with a mean age of 44.2 ± 13.2 years and a type 1 diabetes duration of 18.9 ± 12.7 years were included. Fifteen patients had HH, representing a prevalence of 8.3% (95% confidence interval [CI]: 4.3–12.3%). Age (odds ratio [OR] 1.066 [95% CI: 1.002–1.134]), waist circumference (OR 1.112 [95% CI: 1028–1203]), and insulin requirements ([IU/Kg] ×10 [OR 1.486 {95% CI: 1052–2.098}]) were independently associated with the presence of HH. The model that best predicted HH generated this formula: HH-score = (1.060 × age) + (1.084 × waist circumference) + (14.00 × insulin requirements) + triglycerides, where age was expressed in years, waist circumference in cm, insulin requirements in IU/kg/d, and triglycerides in mg/dL. An HH score > 242.4 showed 100% sensitivity and 53.2% specificity for HH diagnosis; positive and negative predictive values were 17.0 % and 100%, respectively.Conclusions One in 10 men with type 1 diabetes presents HH. This condition is associated with age, waist circumference, and insulin requirements. A simple formula based on clinical parameters can rule out its presence.

    ABSTRACT: Recently, increasing evidences have suggested that inflammatory stress is markedly occurred in the impaired tissue. Thus, the streptozotocin (STZ)-induced diabetic mice were used to investigate the potential renoprotective effect of ramulus mori polysaccharides (RMP) and to discuss the underlying mechanism. The results from the present study showed that RMP significantly lowered the blood glucose and serum levels of glycosylated protein, cholesterol, urea nitrogen (Urea-N), creatinine (Cr) and 24-hour urine protein, while the albumin content was elevated. Meanwhile, the proinflammatory cytokines such as interleukin-6 (IL-6), interferon-gamma (IFN-γ) and tumor necrosis factor alpha (TNF-α) in renal tissue of STZ-lesioned mice were reduced by RMP treatment. Similarly, pathological examination indicated that STZ-induced renal injury was effectively mitigated. In addition, the protein levels of interleukin-1 (IL-1) and interleukin-1 receptor (IL-1R) in renal tissue were notably decreased. Moreover, the endogenous expressions of phosphorylated-IκB (p-IκB) and nuclear factor-kappa B (NF-κB) were down-regulated, respectively. Together, these findings revealed that RMP treatment effectively attenuated STZ-induced cytotoxicity in renal tissue, in which RMP-exerted renoprotection was associated with intrarenally debilitating inflammation reaction through blocking the IL-1/NF-κB pathway, thereby maintaining the renal homeostasis.
