Lipodystrophy is one of the complications of highly active antiretroviral therapies (HAART). This study evaluates the metabolic and endocrine changing in patients with lipodystrophy. Forty patients were evaluated and classified as lipoatrophy, lipohypertrophy and mixed syndrome. We analyzed insulin resistance for HOMA-IR (Homeostasis Model Assesment Insulin Resistance), fasten glucose and OGTT, urea, creatinine, TSH, Free T4, cortisol, DHEA, ratio cortisol/DHEA, prolactin, testosterone (in male), FSH, LH and estradiol (in female), total cholesterol, LDL-c, HDL-c, uric acid. Anthropometrics measures (Weight, height, body mass index, waist, hip and skin folds thickness), ultrasonographic exams for evaluate hepatic steatosis and measure of bone density. The isolated lipohipertrophy occurred only in female (p<0,05). The mean of age was similar in the groups, without changing in the distribution by age group. Dyslipidemia occurred in all groups after HAART (lipodystrophy mixed, 100%, lipohypertrophy, 80% and lipoatrophy, 70%). Antropometric data showed waist increased in the female with lipohypertrophy (98+ 13,4) and decreased in female with lipoatrophy (76,8 + 6,1). Patients with lipoatrophy have been eutrophic (82,4%) and patients with lipohypertrophy have overweight or obesity (60%). Male was associated with osteoporosis (p < 0,05). We found elevated prevalence of the dyslipidemia (85%) and metabolic syndrome (37,5%) in all groups. The metabolic syndrome was associated with lipohypertrophy. No significant changes were found in the thyroid, cortisol, cortisol/DHEA ratio, testosterone, FSH, LH and prolactina. Conclusions: Female is associated with isolated lipohypertrophy, metabolic syndrome and insulin resistance. Male is related with Osteopenia and osteoporosis. Hepatic steatosis were common, but is not influenced for a type of lipodystrophy. Hormonal changing were unusual events in lipodystrophy.

Estudo epidemiológico de agentes virais (HIV, HTLV, VHB e CMV) identificados em adolescentes grávidas atendidas em um centro de referência do Sistema Único de Saúde de Belém, Pará

The prevalence of infection by viral agents such as HIV-1, HTLV1/2, VHB and CMV is not so much known in pregnant teenage population from the North region of Brazil. One of the objectives of this study was to describe the prevalence of infections HIV-1, HTLV1/2, VHB and CMV in pregnant adolescents, attended in a Reference Center in the State of Pará. To achieve the objectives, it was collected blood samples from 324 pregnant adolescents, who came from several cities of the State, from November of 2009 to February of 2010. The samples were submitted to an immuno-enzymatic test (ELISA), in order to detect antibodies Anti- HIV, Anti- HTL V1/2, Anti- VHB and Anti- CMV IgM/ IgG. The serological analysis revealed one serum positive sample for HIV-1, two positives samples for HTLV1/2, while the majority of samples showed antibodies Anti-CMV-IgG, although the occurrence of high infection was low (2.2%). The prevalence of infection for VHB in pregnant adolescents was 0.62%, however a great number (83.3%) of adolescents are susceptible to the infection by VHB, what means they probably were not immunized. The majority of adolescents (63.4%) continued their studies, even though they know about their pregnancy and 34.6% started prenatal later, so they only had a minimum number of four consultations of prenatal. The result reinforces the hypothesis that pregnant adolescents have prevalence for those viral type infections, what is similar to the national pregnant women rates. The prevalence of viral subtypes (HTLV-2 and HIV-1 subtype B) obtained by the molecular characterization of serum positive samples from pregnant adolescents agreed with the prevalence of subtypes from the North region.
