Introduction: Sleep restriction and/or impaired sleep quality negatively influence glucoregulation. The aim of this study was to assess subjective sleep parameters in patients with type 1 diabetes, to relate sleep parameters to long-term glycaemic control, and to assess possible risk factors for impaired sleep.Research design and methods: We studied 99 adult patients with type 1 diabetes (55M, 44F, duration of diabetes 26.9±1.2 years) and 99 age-, g...

Objective: To evaluate prospectively the relationship between Yersinia Enterocolitica (YE) infection and the development of overt autoimmune hypo- or hyperthyroidism (study A) and the de novo occurrence of thyroid antibodies (study B).Subjects and methods: Prospective cohort study of 790 euthyroid women who were 1st or 2nd degree relatives of AITD patients. Follow-up was 5 years, with annual assessments.Study A. Nested case&...

Background and objectives: Non-alcoholic fatty liver disease (NAFLD) is highly prevalent in patients with diabetes as well as the vice versa. It is crucial to identify the characteristics of this group of patients in order to prevent the development, the progression as well as the complications of the disease. We have studied characteristics of patients having both NAFLD and diabetes who are attending a tertiary care institute in Sri Lanka.Methods: A des...

Introduction: Men with the metabolic syndrome have low plasma testosterone (T) levels. We aimed to study whether normalization of plasma T in such men improved features of the metabolic syndrome over the longer term.Design/methods: 145 men, 35 to 70 years, with the metabolic syndrome and hypogonadism (baseline total testosterone level <12.0 nmol/l or calculated free T level <225 pmol/l). They had received treatment for 30 weeks with either parent...

Objective: To determine the predictive risk factors for the development of type 2 diabetes mellitus (DM) in patients with impaired glucose tolerance (IGT) or impaired fasting glucose (IFG) during the 8.5 follow up.Research design and methods: This is an 8-year prospective study in a randomly selected urban population including 2838 subjects aged ≥40 years living in Krakow. Seven hundred and six had IGT (387) or IFG (319) based on WHO criteria and 2...

Background: For many years testosterone therapy in men was considered to be a risk factor for increasing the PSA level and prostate volume as well as blood count parameters. Objective was to investigate the influence of testosterone therapy on prostate and blood count in men with metabolic syndrome and hypogonadism.Methods: In a randomized, placebo-controlled, double-blind, phase III trial (ClinicalTrials.gov identifier: NCT00696748), 184 men suffering f...

Context: Low testosterone level in men is associated with the metabolic syndrome (MetS) as well as with depressive symptoms, low vitality and sexual dysfunction.Objective: To assess the effects of testosterone administration on these subjective symptoms, which have not extensively been studied in hypogonadal men with the MetS. Design: randomized, placebo-controlled trial. Setting: academic, ambulatory, referral centre. Patients: 184 men suffering from bo...

Background: Metabolic syndrome has a high prevalence in male population, leading to the high rate of cardiovascular disease and mortality. Numerous studies show that low androgen levels in men are associated with the metabolic syndrome. This study tested whether normalization of testosterone levels improves metabolic dysregulations and body composition.Methods: In a randomized, placebo-controlled, double-blind, phase III trial (ClinicalTrials.gov identif...

Background: Numerous studies (among which, studies of androgen deprivation in men with prostate cancer) show that low androgen levels in men are associated with the metabolic syndrome. Obesity and particularly visceral fat excess is associated with pro-thrombotic and pro-inflammatory states as well. This study tested whether normalization of testosterone levels improves markers of inflammation.Methods: In a randomized, placebo-controlled, double-blind, p...

Introduction: Transient neonatal diabetes 1 (TNDM1) has an estimated incidence of 1 in 400 000 and is characterised by intra-uterine growth retardation and diabetes presenting soon after birth. Spontaneous remission of diabetes usually occurs within the first year of life. TNDM1 is caused by overexpression of imprinted genes at chromosome 6q24. Three causes have been described: paternal uniparental disomy for chromosome 6; paternally inherited duplication of 6q24; and maternal...
