Heterogeneity and high prevalence of bone manifestations, and bone mineral density in congenital generalized lipodystrophy subtypes 1 and 2.

Introduction: Congenital Generalized Lipodystrophy (CGL) is a rare autosomal recessive disease caused by mutations in genes responsible for the formation and development of adipocytes. Bone abnormalities are described. However, there is a scarcity of data.

Establishment of reference interval for thyroid-stimulating hormone using electrochemiluminescence assay in a healthy adult population from Fortaleza, Brazil.

Objective This study aimed to determine the thyroid-stimulating hormone (TSH) reference interval (RI) and to assess the influence of the use of thyroid ultrasonography (TUS) on reference individual selection from a healthy adult population in Fortaleza, Brazil. Subjects and methods This cross-sectional study recruited patients (N = 272; age = 18-50 years) with normal thyroid function (NTF) and placed them in three groups according to their test results: NTF (n = 272; all participants), TUS (n = 170; participants who underwent thyroid US), RI (n = 124; reference individuals with normal TSH levels). TSH, FT4, TT3, TgAb, and TPOAb concentrations were determined by electrochemiluminescence assay.

Leu124Serfs*26, a novel mutation in congenital generalized lipodystrophy with early cardiovascular complications.

Background: Congenital generalized lipodystrophy (CGL) is a rare autosomal recessive disorder characterized by the near-total loss of subcutaneous adipose tissue soon after birth, resulting in ectopic fat deposition and severe metabolic disturbances. Most cases are caused by or gene mutations. We aimed to report two unrelated CGL patients with a novel frameshift mutation in (p.

Association between cardiovascular autonomic neuropathy and left ventricular hypertrophy in young patients with congenital generalized lipodystrophy.

Background: Congenital generalized lipodystrophy (CGL) is a rare disorder characterized by the absence of subcutaneous adipose tissue, severe insulin resistance, diabetes mellitus, and cardiovascular complications, including cardiac autonomic neuropathy (CAN), left ventricular hypertrophy (LVH), and atherosclerosis. The present study aimed to access the association between CAN parameters and cardiovascular abnormalities in CGL patients.

Methods: A cross-sectional study was conducted with 10 CGL patients and 20 healthy controls matched for age, sex, BMI, and pubertal stage.

Early commitment of cardiovascular autonomic modulation in Brazilian patients with congenital generalized lipodystrophy.

Background: Metabolic abnormalities in congenital generalized lipodystrophy (CGL) are associated with microvascular complications. However, the evaluation of different types of neuropathy in these patients, including the commitment of cardiovascular autonomic modulation, is scarce. The objective of the present study was to determine the prevalence of cardiovascular autonomic neuropathy (CAN) in patients with CGL compared with individuals with type 1 diabetes and healthy subjects.

[Metabolic disorders in emerging and neglected infectious diseases].

The gradual and progressive replacement of infectious and parasitic by chronic diseases as causes of morbidity and mortality, characterizing the process of epidemiological transition hasn't been observed in various populations, especially in underdeveloped or developing countries characterizing a superposition of these profiles (incomplete transition). Besides the increased prevalence of metabolic disorders, various infectious diseases remain endemic in several regions, such as leprosy, tuberculosis, leishmaniasis, viral hepatitis, among others, as well as emerging diseases in recent decades, as HIV infection/Aids. In this context, more attention has been given to the occurrence of metabolic disturbances in the recent years, mainly from the observation of a high incidence of metabolic disorders associated with HIV infection/Aids, and its therapy with antiretroviral drugs.

[Gonadotrophic axis dysfunction in men with HIV-infection/aids].

Gonadotrophic axis dysfunction is commonly observed in HIV-infected patients. The pathogenesis is multifactorial and related to duration of HIV infection, direct cytopathic effects of viruses, use of drugs, opportunistic infections, malignancies, and malnutrition, among other factors. In men, reduced levels of testosterone is associated with loss of muscle mass and strength, decreased bone mineral density, lipodystrophy, depression, asthenia, fatigue and sexual dysfunction.
