ABSTRACT

OBJECTIVE: To evaluate the frequency of non-alcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes mellitus (DM2) and to describe its risk factors. SUBJECTS AND METHODS: Blood samples of 78 patients were collected for assessment of glycemic and lipid profile, liver enzymes, TNF-α and HOMA-IR. The diagnosis of NAFLD was established by ultrasound. RESULTS: NAFLD was observed in 42 percent of patients who had greater BMI (p < 0.001), and frequency of hypertension (p < 0.001). Metabolic syndrome was more frequent in those with NAFLD (p = 0.019). The levels of aspartate, alanine aminotransferase, γ-glutamyl transpeptidase, uric acid, TNF-α, insulin and HOMA-IR were significantly higher in patients with NAFLD than those without NAFLD. CONCLUSION: Almost half of patients with DM2 were found to have NAFLD, and they have more elevated BMI, as well as higher levels of aminotransferases, γ-GT, uric acid, TNF-α, insulin and HOMA-IR than subjects without NAFLD.


OBJETIVO: Avaliar a frequência de doença hepática gordurosa não alcoólica (DHGNA) em pacientes com diabetes mellitus tipo 2 (DM2) e descrever seus fatores de risco. SUJEITOS E MÉTODOS: Amostras de sangue foram coletadas de 78 pacientes para avaliação dos perfis glicídico e lipídico, enzimas hepáticas, TNF-α e HOMA-IR. O diagnóstico de DHGNA foi estabelecido por ultrassonografia. RESULTADOS: NAFLD foi observada em 42 por cento dos pacientes que apresentaram maior IMC (p < 0,001). Hipertensão arterial sistêmica (p < 0,001) e síndrome metabólica foram mais frequentes naqueles com DHGNA (p = 0,019). Os níveis de aspartato aminotransferase, alanina aminotransferase, γ-glutamil transpeptidase, ácido úrico, TNF-α, insulina e HOMA-IR foram significativamente maiores nos pacientes com do que naqueles sem DHGNA. CONCLUSÃO: Quase metade dos pacientes com DM2 apresentaram DHGNA, os quais tiveram IMC mais elevado, bem como maiores níveis de aminotransferases, γ-GT, ácido úrico, TNF-α, insulina e HOMA-IR do que os indivíduos sem DHGNA.

ABSTRACT

OBJECTIVE: To compare the efficacy and tolerability of metformin, rosiglitazone and gliclazide MR as monotherapy and in combination in the treatment of type 2 diabetes. SUBJECTS AND METHODS: 250 patients treated with oral antidiabetic agents for at least 24 weeks in monotherapy or in combination therapy were included in this retrospective study. RESULTS: As monotherapy the reduction of fasting plasma glucose (FPG), postprandial glycemia (PPG) and HbA1c was similar with the three drugs after 24 weeks. Among patients on combination therapy, the reduction in HbA1c, FPG and PPG was significantly lower with rosiglitazone plus metformin, as compared to metformin plus gliclazide MR or gliclazide MR plus rosiglitazone. Patients treated with rosiglitazone achieved less favorable changes in lipid profile. CONCLUSION: In monotherapy all drugs were equally effective in improving glycemic control, whereas the combination of metformin plus gliclazide MR provided the best results concerning the improvement of both, glycemic control and lipid profile.


OBJETIVO: Comparar a eficácia e a tolerabilidade da metformina, rosiglitazona e gliclazida MR em monoterapia ou em combinação no tratamento do diabetes tipo 2. SUJEITOS E MÉTODOS: 250 pacientes tratados com antidiabéticos orais por pelo menos 24 semanas, em monoterapia ou em terapia combinada, foram incluídos neste estudo retrospectivo. RESULTADOS: Como monoterapia, a redução da glicemia de jejum (GJ), glicemia pós-prandial (GPP) e HbA1c foi similar com as três drogas, após 24 semanas. Entre os pacientes em terapia combinada, a redução da HbA1c, GJ e GPP foi significativamente menor com rosiglitazona e metformina, em comparação com metformina e gliclazida MR ou gliclazida MR mais rosiglitazona. Os pacientes tratados com rosiglitazona obtiveram mudanças menos favoráveis no perfil lipídico. CONCLUSÃO: Em monoterapia todos os medicamentos foram igualmente eficazes na melhora do controle glicêmico, enquanto a combinação de metformina e gliclazida MR proporcionou os melhores resultados relativos à melhoria de ambos, controle glicêmico e perfil lipídico.
