ABSTRACT
The effects of chromium picolinate in Type 2 diabetic patients are investigated. Seventeen Type 2 diabetic patients were randomly divided into two groups. The experimental group received fiber-rich hypocaloric diet and chromium picolinate whereas the control group received fiber-rich hypocaloric diet and placebo. The chromium picolinate was offered twice a day at the dose of 100 µg. Anthropometric data such as blood pressure, fasting glycemia and glycated hemoglobin (HbA1c) were measured and these parameters were evaluated again after 90 days. No difference was reported in rates of body weight, waist, hip, body mass index, blood pressure and fasting glycemia (Control vs. Experimental groups) after treatment. However, a decrease (p = 0.0405) of HbA1c occurred in the experimental group when the pre-and post-treatment rates were compared. HbA1c data showed that chromium picolinate improved the glycemic control in Type 2 diabetes.
Neste estudo investigamos os efeitos do picolinato de cromo em pacientes portadores de Diabetes mellitus tipo 2. Para alcançar este objetivo 17 pacientes foram aleatoriamente divididos em 2 grupos. O grupo Experimental recebeu dieta hipocalórica rica em fibras e picolinato de cromo enquanto o grupo Controle recebeu dieta hipocalórica rica em fibras e placebo. Picolinato de cromo foi oferecido na dose de 100 µg, 2 vezes ao dia. Avaliamos os dados antropométricos, pressão arterial, glicemia de jejum e hemoglobina glicada A1c (HbA1c), sendo estes parâmetros reavaliados após 90 dias. Os resultados de peso, cintura, quadril, índice de massa corpórea, pressão arterial e glicemia de jejum, antes e após o tratamento não foram diferentes (Controle vs. Experimental). Contudo, houve redução (p = 0,0405) da HbA1c no grupo Experimental, ao compararmos os valores antes e após o tratamento. Portanto, a partir dos dados de HbA1c foi possível evidenciar que o picolinato de cromo melhora o controle glicêmico no Diabetes mellitus tipo 2.

The aim of this study was to determine whether plasma levels of carbonylated proteins, total antioxidant capacity (TAC) and reduced protein thiols could be suitable biomarkers of risk factors for diabetic foot. Individuals with type 2 diabetes with normal protective sensation (normal foot group) vs. loss of protective sensation and/or signs of peripheral arterial disease and/or foot deformities and/or history of ulcers and/or neuropathic fractures and/or amputation (diabetic foot group) were compared. The diabetic foot group showed higher carbonylated protein levels (P = 0.0457) and lower levels of TAC (P = 0.0148) and reduced protein thiols (P = 0.0088), compared with the normal foot group. In general, several other parameters of risk of diabetes complication (blood levels of glycated hemoglobin, glucose and cholesterol, duration of diabetes, body mass index and waist circumference) showed a tendency of higher values in the diabetic foot group. The results suggest that the plasma levels of carbonylated proteins, TAC and reduced protein thiols could furnish information about the risk of diabetic foot, considering that the changes in these biomarkers were associated with the loss of sensitivity and foot ulcerations.
ABSTRACT
Investigou-se o perfil de 80 pacientes diabéticos tipo 2 (PDT2), constituído de homens (45%) e mulheres (55%) com média de idade de 62,8 ± 8,5 anos, usuários de insulina NPH fornecida pela Secretaria Municipal de Saúde de Maringá, PR, Brasil. Obteve-se informações por meio de um questionário e pela medida do índice de massa corporal (IMC). Verificou-se que: 1) 72% apresentavam obesidade ou sobrepeso; 2) 67,5% utilizavam antihipertensivos dos quais os inibidores da enzima conversora (ECA) e os bloqueadores dos receptores de angiotensina (BRA) representavam 84%; 3) O IMC foi similar em PDT2 usuários ou não de agentes antihipertensivos; 4) 46% além da insulina utilizavam antidiabéticos orais; 5) a dose de insulina (unidades. kg-1. dia-1) foi inferior (p< 0,05) em usuários de antihipertensivos, sugerindo existir uma correlação entre terapia antihipertensiva e o uso de menores doses de insulina. Este efeito ocorreria de maneira independente do IMC ou da simultânea a terapia com antidiabéticos orais.
The profile of 80 type-2 diabetic patients (T2DP), male (45%) and female (55%), with mean age 62.8 ± 8.5 years old, receiving NPH insulin from the municipal health department of Maringa city, PR, Brazil, was investigated. Information about each volunteer was obtained using a questionnaire and an evaluation of body mass index (BMI). It was verified that: 1) 72% showed obesity or overweight; 2) 67.5% used antihypertensive drugs in which angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARB) were the main antihypertensive drugs (84%); 3) The BMI was similar in the T2DP with hypertension or without hypertension; 4) 46%, in addition to insulin therapy, also used antidiabetic drugs; 5) The daily dose of insulin (units. kg-1. day-1) in the group which received antihypertensive therapy was lower (p< 0.05), suggesting the presence of a relationship between antihypertensive treatment and lower doses of insulin. In addition, this relationship would occur independently of the influence of BMI or the simultaneous treatment with oral antidiabetic drugs.

O pé diabético é uma das complicações crônicas mais devastadoras em pacientes diabéticos, gerando alto impacto social e econômico, além de diminuir a qualidade de vida. Neste estudo exploratório-descritivo foram avaliados 39 pacientes diabéticos tipo 2 (PDT2), atendidos pelo Laboratório de Ensino e Pesquisa da Universidade Estadual de Maringá (agosto/2009 e abril/2010). Os pacientes foram submetidos a uma entrevista para obtenção de informações sobre o perfil socioeconômico e a avaliação laboratorial da glicemia e lipidemia (perfil metabólico). Os resultados revelaram: prevalência do gênero feminino, média de idade de 60,1 ± 9,5 anos, 71,8% tinham Ensino Fundamental incompleto, 61,5% eram casados, 74,3% eram sedentários, o tempo de doença foi de 9,2 ± 7,3 anos, 53,8% desconheciam os cuidados e complicações do pé e 70,6% estavam com a hemoglobina glicada alterada. Conclui-se que a baixa escolaridade e pouco conhecimento em relação à doença comprometem o processo de autocuidado, aumentando as chances do aparecimento das complicações crônicas.
Diabetic foot is one of the most devastating chronic complications of diabetic patients, causing high social and economic impact and decreased quality of life. In this exploratory-descriptive study were evaluated 39 patients with type 2 diabetes (T2DP) attended by the Clinical Analysis Teaching and Research Laboratory of the State University of Maringá (August/2009 and April/2010). Patients underwent an interview to obtain information on the socioeconomic profile and laboratory evaluation of blood glucose and lipids (metabolic profiling) The results revealed prevalence of female, mean age was 60.1 ± 9.5 years, 71.8% had incomplete primary education, 61.5% were married, 74.3% were sedentary, disease duration was 9.2 ± 7.3 years, 53.8% were unaware of the care and foot complications and 70.6% had glycated hemoglobin altered. We conclude that low education and little knowledge about the disease decreased the process of self-care, increasing the chances of development of chronic complications.
