Preenchimento facial com Polimetilmetacrilato em pacientes que vivem com a síndrome da imunodeficiência adquirida (AIDS) / Facial filling with polymethylmethacrylate in patients with acquired immunodeficiency syndrome

INTRODUÇÃO: Pacientes que vivem com síndrome da imunodeficiência adquirida (AIDS) em uso da Terapia Antirretroviral de Alta Potência (TARV) são suscetíveis a desenvolver síndrome lipodistrófica. O preenchimento facial com polimetilmetacrilato é opção de tratamento. O objetivo é analisar o procedimento de preenchimento facial e avaliar os pacientes em relação à percepção, incômodo, revelação do diagnóstico, expectativa quanto ao preenchimento e a satisfação e impacto em suas vidas. MÉTODOS: Análise em 63 pacientes submetidos ao preenchimento facial. Foram realizados procedimentos, analisados prontuários dos pacientes e o Protocolo do Ambulatório de Lipodistrofia do Programa Municipal de doenças sexualmente transmissíveis (DST)/AIDS e Hepatites Virais de São Bernardo do Campo, atendidos no período de janeiro a julho de 2009. RESULTADOS: Todos os 63 pacientes iniciais que concordaram em participar da pesquisa permaneceram até o término deste trabalho. Apenas seis pacientes (9,5%) eram de origem de outros municípios, enquanto 57 pacientes (90,5%) eram moradores de São Bernardo. 68,2% eram homens e 100% brancos. A média das idades foi 49,7 anos. Em média, o Vírus da Imunodeficiência Humana (HIV) foi diagnosticado há 11,5 anos, com tempo médio de uso de TARV por 10 anos e tempo médio de lipoatrofia facial de 3,8 anos. A maioria fez uso de Estavudina e/ou Efavirenz. Quem ficava mais desconfortável com as alterações na face eram os próprios pacientes. 85,7% não revelaram o diagnóstico para terceiros. 100% dos pacientes ficaram satisfeitos ou muito satisfeitos com o resultado obtido. CONCLUSÃO: 100% dos pacientes ficaram satisfeitos ou muito satisfeitos com o resultado obtido. Em 100% dos casos houve um impacto favorável na vida. Não houve efeitos adversos ao procedimento cirúrgico de preenchimento.

INTRODUCTION: Patients with acquired immunodeficiency syndrome (AIDS) who use highly active antiretroviral therapy (HAART) can develop lipodystrophy syndrome, for which facial filling with polymethylmethacrylate is a treatment option. The objective is to analyze the procedure of facial filling and evaluate patients in relation to their perception, discomfort, revelation of the diagnosis to third parties, expectation concerning facial filling, and satisfaction with the treatment outcome and its impact on their lives. METHODS: Sixty-three patients who underwent facial filling were evaluated. Procedures performed between January and July 2009 were assessed, the records of the patients were analyzed, and the outpatient lipodystrophy protocol of the STD/AIDS and Viral Hepatitis Municipal Program of São Bernardo do Campo was used. RESULTS: All the 63 patients who agreed to participate in the research completed the study. Only 6 patients (9.5%) were from other municipalities, while 57 patients (90.5%) were residents of São Bernardo. Of the patients, 68.2% were men and 100% were Caucasian. The mean age of the patients was 49.7 years. Human immunodeficiency virus was diagnosed 11.5 years prior on average, with 10-year average use of HAART and 3.8-year average time of facial lipoatrophy. Most of the patients used stavudine and/or efavirenz. The patients themselves felt more uncomfortable with facial changes. Among the patients, 85.7% did not reveal the diagnosis to third parties. CONCLUSION: All of the patients were satisfied or very satisfied with the result obtained, which had a favorable impact on their lives. The filling surgical procedure had no adverse effects.

Association between antiretrovirals and thyroid diseases: a cross-sectional study

Objective This study aims to estimate the prevalence of thyroid diseases and anti-TPO status. We searched for an association among presence of immune reconstitution and use of stavudine, didanosine and protease inhibitors with thyroid diseases. Materials and methods A cross-sectional study was performed to analyze the records of 117 HIV-infected patients who had their CD4+ cell count, viral load, anti-TPO, TSH and free T4 levels collected on the same day. Immune reconstitution was considered in those whose T CD4+ count was below 200 cells/mm3, but these values increased above 200 cells/mm3 after the use of antiretrovirals. The odds ratio obtained by a 2x2 contingency table and a chi-square test were used to measure the association between categorical variables. Results The prevalence of thyroid disease was 34.18%; of these, 4.34% were positive for anti-TPO. There was an association of risk between stavudine use and subclinical hypothyroidism (OR = 4.19, 95% CI: 1.29 to 13.59, X2 = 6.37, p = 0.01). Immune reconstitution achieved protection associated with thyroid disease that was near statistical significance OR = 0.45, 95% CI: 0.19 to 1.04, X2 = 3.55, p = 0.059. Conclusion The prevalence of thyroid disease in the sample studied was higher than what had been found in the literature, with a low positive anti-TPO frequency. The historical use of stavudine has an association of risk for the presence of subclinical hypothyroidism, and immune reconstitution has trends towards protection for the presence of thyroid diseases. .

Pharmacokinetics of lamivudine & stavudine in generic fixed-dose combinations in HIV-1 infected adults in India.

Background & objectives: Antiretroviral drug concentrations are important determinants of clinical response to a drug accounting for both toxicity and efficacy. Several factors such as age, ethnicity, body weight and patients’ immune status may influence antiretroviral drug concentrations. The aim of the study was to determine the influence of immunological status, sex and body mass index on the steady state pharmacokinetics of lamivudine (3TC) and stavudine (d4T) in HIV-infected adults, who were undergoing treatment with generic fixed dose combinations (FDC) of these drugs in India. Methods: Twenty seven HIV-1 infected patients receiving antiretroviral treatment (ART) for at least two weeks at the Government ART clinic at Tambaram, Chennai, took part in the study. Serial blood samples were collected predosing and at different time points after drug administration. Plasma 3TC and d4T levels were estimated by HPLC. Results: The patients’ immune status, sex or body mass index had no impact on the pharmacokinetics of 3TC. In the case of d4T, peak concentration was significantly lower in patients with CD4 cell counts < 200 cells/μl than those with ≥ 200 cells/ μl (P < 0.05), but were within the therapeutic range. The mean CD4 cell counts increased from 101 cells/μl at initiation of ART to 366 cells/μl at 12 months of treatment. Interpretation & conclusions: Blood levels of 3TC and d4T drugs that are part of generic FDCs commonly used by HIV-infected individuals in India were within the therapeutic range and not influenced by nutritional or immune status. There was a significant improvement in CD4 cell counts over 12 months of treatment. Indian generic FDCs manufactured and used widely in the developing world provide effective concentrations of antiretroviral drugs.

Significant differences between plasma HIV-1 RNA assays in HIV-1 subtype E infected patients treated with antiretroviral therapy.

A total of 72 HIV-1 infected Thai patients treated with didanosine (ddI) or stavudine (d4T) plus ddI at the time of interim analysis were analyzed. Sixty patients (83%) carried subtype E documented by HIV-1 V3 serotyping. HIV-1 RNA levels were measured using three commercial viral load assays. At baseline (n = 57), Quantiplex 2.0 and NucliSens 2.0 showed mean log10 HIV-1 RNA of 0.7 log10 or 5 fold lower than Amplicor 1.5 (mean 4.29 versus 5.0 log10, respectively, p < 0.001). At week 20 of treatment (n = 29), HIV-1 RNA levels were detected in 55.2%, 31%, and 33.5% of subjects tested by Amplicor 1.5, Quantiplex 2.0, and NucliSens 2.0, respectively. In conclusion: plasma HIV-1 RNA analyses showed comparable values with Quantiplex 2.0 and NucliSens 2.0 assays. In contrast, Amplicor 1.5 resulted in approximately 5 folds higher HIV-1 RNA levels and a 25% higher rate of detection of plasma HIV-1 RNA as compared to the other two assays. As the current goal of therapy is to suppress plasma viral load below the detection limit of the assays, the significant differences between the assays may influence antiretroviral efficacy evaluation and management.
