There is still no consensus about the best strategy to screen Addison’s disease (AD) in type 1 diabetes mellitus (T1DM) patients. OBJECTIVE: The aim of this study was to determine the frequency of anti-21-hydroxilase (anti-21OH) in a multiethnic T1DM population and investigate if its presence is associated with any adrenal dysfunction or thyroid autoimmunity. METHODS: Forty individuals underwent an interview and blood was drawn for anti-thyroperoxidase (anti-TPO), anti-21OH, TSH, free T4 and cortisol measurement. RESULTS: Anti-21OH was found in 7.5% […]

PURPOSE: Check the evolution of type 1(T1) diabetic patients to hypertension and prehypertension and baseline factors related to final blood pressure levels (BP). METHODS: Observational study involving 127 T1 diabetic patients submitted to clinical and laboratorial evaluation and followed by for 5 (2.4-9.2) years. RESULTS: From the initially normotensive patients, 21.7% developed prehypertension, 4.7% developed hypertension and 73.6% remained with normal BP. From the prehypertensive patients, 35% returned to normal BP, 50% remained prehypertensive and 15% developed hypertension. The relative […]

OBJECTIVES: To estimate the prevalence of type 1 diabetes mellitus (DM1) and celiac disease association and to verify the existence of celiac disease symptoms, as well as the occurrence of other autoimmune diseases among the patients, their first-degree relatives and the possible influences of celiac disease in diabetes control. METHODS: It was done a cross-sectional study with 195 patients that answered a questionnaire about gastrointestinal symptoms and the occurrence of autoimmune diseases in their first-degree relatives. IgA was measured and […]

Lipodystrophy in HIV-infected patients (LDHIV) affects 40-50% of HIV-infected patients, but there are no data on its prevalence in Brazil. The aim of this study was to assess the LDHIV prevalence among HIV-infected adult Brazilian individuals, as well as to evaluate LDHIV association with cardiovascular risk factors and the metabolic syndrome (MS). It was included 180 adult HIV-infected outpatients consecutively seen in the Infectology Clinic of Universidade Estadual de Londrina.

Paget’s disease of bone is a focal disorder of bone remodeling accompanied initially by an increase in bone resorption, followed by a disorganized and excessive formation of bone, leading to pain, fractures and deformities. It exhibits a marked geographical variation in its prevalence. In Brazil it predominantly affects persons of European descent. The majority of the reported cases of the disease in Brazil are from Recife, owing to its peculiar mixed European colonization over approximately four centuries. The etiology is […]

The goal of this study was to determine the prevalence of Metabolic Syndrome (MS) in a semi-arid rural area in Bahia, motivated by the increase of impaired glucose tolerance in rural populations and the scant national data about the occurrence of MS. Total sample involved 240 adults > 25 years, randomly selected, 102 (42.5%) men and 138 (57.5%) women, mean age 49.5 ± 14.9, ranging from 25 to 87 years.

The aim of this population-based study was to estimate the prevalence of overweight and obesity in public and private schools of Santos city, Brazil. We evaluated a total of 10,822 children aged 7 to 10 years old. Determination of overweight and obesity was obtained by the 85th and 95th percentiles of BMI for age, respectively, as proposed by CDC in 2000. The overall prevalence rates of overweight and obesity were 15.7% (CI 95%= 15.0% to 16.4%) and 18.0% (17.3% to […]

The relationship between cancer and acromegaly has been subject of study for many years. From a case of differentiated thyroid carcinoma in one of our acromegalic patients, we reviewed a series of 100 acromegalics and found two others cases of thyroid cancer, which are described in this work. From that point, we have got data from the literature about this last association and its possible pathogenesis. The prevalence of thyroid disease is increased among acromegalic patients, mainly due to nodular […]
