ABSTRACT

BACKGROUND:

Isotretinoin has been used to treat the most severe cases of acne; however, it may provoke adverse events in mucocutaneous and hepatic tissues, lead to alterations in lipid levels and cause teratogenicity.

OBJECTIVE:

The objective of this study was to evaluate the profile of changes in alanine aminotransferase (ALT), aspartate aminotransferase (AST) and triglyceride levels in patients who had been treated with oral isotretinoin dispensed by the São Mateus/ES pharmacy for special drugs.

METHODS:

A retrospective, observational, longitudinal study was conducted by carrying out a secondary analysis of each patient's data.

RESULTS:

Of the 130 patients who received isotretinoin between January and December 2009, only 70 were actually treated for 3 months or more and handed in the results of their laboratory tests. Of these 70 patients, 39 (55.7%) were female. The mean age of the women (23.9 years) was higher than the mean age of the men (20.1 years). There was a statistically significant increase in the levels of triglycerides (87.01 ± 48.25 versus 105.32 ± 48.76 mg/dL), AST (20.44 ± 6.26 versus 24.38 ± 11.92 U/L) and ALT (18.24 ± 8.31 versus 23.34 ± 20.03 U/L) performed prior to and 3 months or more after oral isotretinoin treatment. After treatment with oral isotretinoin, triglyceride levels had increased beyond the normal range in 11% of the patients, while 8.6% had elevated AST levels and 7.3% had increased ALT levels.

CONCLUSION:

The results in this population show that the use of oral isotretinoin for the treatment of acne may result in altered triglyceride, AST and ALT levels. These findings are in accordance with data published previously in the scientific literature, confirming the need to monitor these patients.
RESUMO
FUNDAMENTOS A isotretinoína tem sido usada no tratamento dos casos mais graves de acne, embora possa induzir reações adversas nos tecidos mucocutâneos e hepáticos, alterações nos níveis lipídicos e teratogenicidade.

OBJETIVOS:

Este estudo avaliou o perfil de alterações nas concentrações de Alanina Aminotransferrase, Aspartato Aminotransferrase e triglicerídeos em pacientes que fizeram uso de isotretinoína oral fornecida pelo serviço Farmácia de Medicamentos Excepcionais de São Mateus/ES.

MÉTODOS:

Foi realizado estudo observacional longitudinal exploratório retrospectivo, utilizando coleta de dados secundários de cada paciente.

RESULTADOS:

Dos 130 pacientes que receberam isotretinoína no período de janeiro a dezembro de 2009, somente 70 realizaram o tratamento por 3 meses ou mais e apresentaram os resultados dos exames. Desses 70 pacientes, 39 (55,7%) eram do sexo feminino. A média de idade das mulheres (23,9 anos) foi maior do que a média de idade dos homens (20,1 anos). Houve aumento estatisticamente significante nas dosagens de triglicerídeos (87,01±48,25 versus 105,32 ± 48,76), Aspartato Aminotransferrase (20,44 ± 6,26 versus 24,38 ± 11,92) e Alanina Aminotransferrase (18,24 ± 8,31 versus 23,34 ± 20,03), realizadas antes e após 3 meses ou mais de tratamento com isotretinoína oral. Após o tratamento com isotretinoína oral, 11% dos pacientes apresentaram elevação de triglicerídeos acima dos valores normais, 8,6% apresentaram elevação da Aspartato Aminotransferrase e 7,3% tiveram elevação da Alanina Aminotransferrase.

CONCLUSÃO:

Os resultados mostraram que o uso de isotretinoína oral para o tratamento da acne, na população estudada, pode levar a alterações nas dosagens de triglicerídeos, Alanina Aminotransferrase e Aspartato Aminotransferrase, como mostrado pela literatura científica, confirmando a necessidade de monitoramento.
