Glutamine dipeptide supplementation improves clinical responses in patients with diabetic foot syndrome

Abstract

The effect of glutamine dipeptide (GDP) supplementation in patients with diabetic foot syndrome was evaluated. A total of 22 patients took part in the study. GDP was supplied in 10 g sachets, and was dissolved in water immediately before use, with ingestion once a day, after lunch or after dinner (20 g/day) over a period of 30 days. Quantification of foot insensitive areas, oxidative stress, blood cytokines, and biochemical, hematological and toxicological parameters was performed before and after GDP supplementation. We observed an increase in blood levels of interferon-α (P=0.023), interferon-γ (P=0.038), interleukin-4 (P=0.003), interleukin-6 (P=0.0025), interleukin-7 (P=0.028), interleukin-12 p40 (P=0.017), interleukin-13 (P=0.001), leukocytes (P=0.037), eosinophils (P=0.049), and typical lymphocytes (P<0.001) due to GDP administration. In addition, we observed a reduced number (P=0.048) of insensitive areas on the foot, and reduction (P=0.047) of fasting hyperglycemia. Patients also showed increased blood high density lipoprotein (P<0.01) and protein thiol groups (P=0.004). These favorable results were associated with the absence of renal and hepatic toxicity. These results are of clinical relevance, since supplementation with GDP over 30 days improved clinical responses in patients with diabetic foot syndrome.Uniterms: Type 2 diabetes mellitus/treatment/study.

Tratamento de lesões nos pés de pessoas com diabetes mellitus no cenário brasileiro: revisão integrativa

“…As outras formas de tratamento, como cobertura de celulose com anti-inflamatório Ibuprofeno, cirurgia minimamente invasiva, suplementação com dipeptídeo de glutamina, ozônio tópico e implante de células cutâneas autólogas, também apresentaram efeitos positivos na reparação tecidual e na cura de úlceras por pé diabético (33)(34)(35)(36)(37) . Observa-se, portanto, que essas terapias ainda estão em teste e são pouco implementadas no dia a dia da prática dos enfermeiros, principalmente no…”
