P450c17 deficiency is an autosomal recessive disorder and a rare cause of congenital adrenal hyperplasia characterized by hypertension, hypokalemia, and impaired production of sex hormones. We performed a clinical, hormonal, and molecular study of 11 patients from 6 Brazilian families with the combined 17alpha-hydroxylase/17,20-lyase deficiency phenotype.(More)
OBJECTIVE To determine the prevalence of metabolic syndrome (MetS) in schoolchildren from 6 to 16 years old, while considering their socio-economic status and other potential risk factors. DESIGN A cross-sectional study was conducted between April and November of 2005 in a semi-rural city with a total population of 13,000 inhabitants. SETTING The study(More)
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(More)
The purpose of this study was to assess metformin effects on high-density lipoprotein (HDL) composition of patients with HIV-associated lipodystrophy (LDHIV). Twenty-four adult outpatients were enrolled to receive metformin (1700 mg/d) during 6 months, but 2 were lost to follow-up and 6 stopped the drug due to adverse events (gastrointestinal in 5, and(More)
BACKGROUND The magnitude of lipoprotein level reduction during the acute-phase response may be associated with the severity and mortality of sepsis. However, it remains to be determined whether low lipoprotein levels can be considered a risk factor for developing sepsis. We aimed to investigate lipoprotein levels as risk factors for sepsis in hospitalized(More)
1. The hepatic mechanisms involved in the simultaneous regulation of plasma cholesterol concentration and cholesteryl ester transfer protein (CETP) activity were investigated by sharply modifying the hepatic rates of cholesterol synthesis. This was accomplished by cholestyramine, lovastatin and cholesterol feeding in human CETP transgenic mice cross-bred(More)
BACKGROUND Transfusion of allogeneic blood influences outcome after surgery. Despite widespread availability of transfusion guidelines, transfusion practices might vary among physicians, departments, hospitals and countries. Our aim was to determine the amount of packed red blood cells (pRBC) and blood products transfused intraoperatively, and to describe(More)
Several clinical settings are associated with specific coagulopathies that predispose to uncontrolled bleeding. With the growing concern about the need for optimizing transfusion practices and improving treatment of the bleeding patient, a group of 9 Portuguese specialists (Share Network Group) was created to discuss and develop algorithms for the clinical(More)
Prader-Willi syndrome (PWS) is a genetic disorder frequently characterized by obesity, growth hormone deficiency, genital abnormalities, and hypogonadotropic hypogonadism. Incomplete or delayed pubertal development as well as premature adrenarche are usually found in PWS, whereas central precocious puberty (CPP) is very rare. This study aimed to report the(More)
AIMS Patients with type 1 diabetes, in the absence of chronic complications, have serum concentrations of high density lipoprotein cholesterol (HDL-C) similar to the general population. However, their HDL particles may be dysfunctional. We aimed to evaluate the antioxidant effect of HDL2 and HDL3 obtained from Caucasian males with type 1 diabetes with(More)
