RESUMO
OBJECTIVE: To evaluate the effectiveness of adding vildagliptin to the treatment of patients with inadequately controlled type 2 diabetes mellitus (T2DM) treated with a combination of metformin and a sulphonylurea. SUBJECTS AND METHODS: 37 T2DM patients with HbA1c ranging from 7.7% to 12.4% (mean of 9.30 ± 1.38), despite the use of metformin in combination with a sulphonylurea, were additionally treated with vildagliptin (100 mg/day) for at least 6 months. RESULTS: During triple oral therapy (TOT) HbA1c levels < 7% were achieved in 11 patients (29.7%), whereas levels of fasting plasma glucose (FPG) < 120 mg/dL were observed in 12 patients (32.4%). Both findings were observed in 10 patients (27.0%). Compared to nonresponsive subjects, lower mean baseline HbA1c and FPG levels were seen in responsive patients, but the difference was only statistically significant for fasting plasma glucose (FPG). Moreover, there was considerable overlap between the two groups. CONCLUSION: Our preliminary results suggest that TOT with metformin, a sulphonylurea and vildagliptin may be useful for some T2DM patients nonresponsive to combination therapy with metformin and sulphonylurea.

OBJECTIVE: To evaluate the effectiveness of adding vildagliptin to the treatment of patients with inadequately controlled type 2 diabetes mellitus (T2DM) treated with a combination of metformin and a sulphonylurea. SUBJECTS AND METHODS: 37 T2DM patients with HbA1c ranging from 7.7 percent to 12.4 percent (mean of 9.30 ± 1.38), despite the use of metformin in combination with a sulphonylurea, were additionally treated with vildagliptin (100 mg/day) for at least 6 months. RESULTS: During triple oral therapy (TOT) HbA1c levels < 7 percent were achieved in 11 patients (29.7 percent), whereas levels of fasting plasma glucose (FPG) < 120 mg/dL were observed in 12 patients (32.4 percent). Both findings were observed in 10 patients (27.0 percent). Compared to nonresponsive subjects, lower mean baseline HbA1c and FPG levels were seen in responsive patients, but the difference was only statistically significant for fasting plasma glucose (FPG). Moreover, there was considerable overlap between the two groups. CONLUSION: Our preliminary results suggest that TOT with metformin, a sulphonylurea and vildagliptin may be useful for some T2DM patients nonresponsive to combination therapy with metformin and sulphonylurea.
OBJETIVO: Avaliar a eficácia da adição de vildagliptina ao tratamento de pacientes com diabetes melito tipo 2 (DM2) inadequadamente controlados com a terapia de combinação com metformina e sulfonilureia. SUJEITOS E MÉTODOS: 37 pacientes com DM2 e HbA1c variando entre 7,7 por cento e 12,4 por cento (média, 9,30 ± 1,38), apesar do uso de metformina associada a uma sulfonilureia, foram adicionalmente tratados com vildagliptina (100 mg/dia) durante, pelo menos, 6 meses. RESULTADOS: Durante a terapia oral tripla TOT), níveis de HbA1c < 7 por cento foram alcançados em 11 pacientes (27,9 por cento), enquanto a glicemia de jejum (GJ) < 120 mg/dL foi observada em 12 pacientes (32,4.1 por cento). Ambos os resultados foram descritos em 10 pacientes (27,0 por cento). Em comparação com indivíduos não responsivos, os pacientes responsivos tinham níveis basais mais baixos de HbA1c e GJ, mas a diferença foi estatisticamente significativa somente para glicemia de jejum. Além disso, houve grande sobre-posição entre os dois grupos. CONSLUSÃO: Nossos resultados preliminares sugerem que a TOT com metformina, uma sulfonilureia e vildagliptina pode ser útil para alguns pacientes com DM2 não responsivos à combinação com metformina e uma sulfonilureia.
