          Abstract

          OBJECTIVE: The aim of this study is to assess the clinical care pattern and to compare the lipid and glycemic profile in a group of diabetic patients undergoing both hemodialysis (HD) and peritoneal dialysis (PD) and to correlate these data using biomarkers of cardiovascular risk. SUBJECTS AND METHODS: The first phase consisted in performing a survey on demographic data, questions about the medical team and glycemic control. In the second phase, patients were assessed through laboratorial data on their glycemic and lipid profile at a single center for HD and PD. RESULTS: 91 patients was the total population; 70 patients (77%) answered the survey; 66 patients (94%) considered the nephrologist the physician responsible for caring for their glycemic control. Second phase: 59 patients were assessed, 29 undergoing HD and 30 undergoing PD. Fifty-seven percent of the patients had HbA1c above 7%; the level of glycemic markers in patients undergoing peritoneal dialysis was significantly higher than in patients undergoing hemodialysis: HbA1c (9.37 ± 0.5) vs. (7.37 ± 0.49) p < 0.01; fasting glycemia (170 ± 15) vs. (126 ± 15) mg/dL p < 0.05. We found a positive correlation between HbA1c and hyperfibrinogenemia (r = 0.4437, p < 0.0005). CONCLUSIONS: The data reveal that glycemic control in diabetic patients undergoing renal replacement therapy (RRT) is neglected. Peritoneal dialysis is related to the worst level of glycemic markers, possibly due to the glucose content in the dialysis solution, and higher levels from HbA1c have a positive correlation with hyperfibrinogenesis in this population.

          OBJETIVO: Avaliar as características dos cuidados clínicos dos pacientes em diálise, comparar o controle glicêmico e lipídico entre os pacientes diabéticos em hemodiálise (HD) e em diálise peritoneal (DP) e correlacionar os dados laboratoriais com biomarcadores de risco cardiovascular. SUJEITOS E MÉTODOS: A primeira etapa consistiu de um questionário abordando variáveis demográficas, questões sobre a equipe multidisciplinar, incluindo a equipe médica e sobre o controle glicêmico. Na segunda, os pacientes foram avaliados com exames laboratoriais para controle glicêmico e perfil lipídico numa unidade de HD e DP. RESULTADOS: Dos 91 pacientes avaliados, setenta (77%) responderam ao questionário. Destes, 66 (94%) consideraram o nefrologista o médico responsável pelo cuidado do seu controle glicêmico. Na segunda etapa, foram avaliados 59 pacientes: 29 em HD e 30 em DP. Cinquenta e sete por cento dos pacientes diabéticos em diálise apresentaram HbA1c acima de 7%, sendo que aqueles em diálise peritoneal apresentam níveis de marcadores glicêmicos significativamente piores do que os pacientes diabéticos em HD, HbA1c: (9,37 ± 0,5) vs. (7,37 ± 0,49) p < 0.01; glicemia de jejum: (170 ± 15) vs. (126 ± 15) mg/dL, p < 0.05. Encontramos uma correlação positiva entre HbA1c e hiperfibrinogenemia (r = 0.4437, p < 0.0005). CONCLUSÕES: Nossos dados permitem inferir que o controle glicêmico da população diabética em terapia renal de substituição (TRS) é negligenciado. A diálise peritoneal está relacionada com piora nos níveis de marcadores glicêmicos, possivelmente em decorrência do conteúdo de glicose das soluções de diálise, e os níveis elevados de HbA1c estão associados com hiperfibrinogenemia nesta população.

            Inflammation, stress, and diabetes.

            Over the last decade, an abundance of evidence has emerged demonstrating a close link between metabolism and immunity. It is now clear that obesity is associated with a state of chronic low-level inflammation. In this article, we discuss the molecular and cellular underpinnings of obesity-induced inflammation and the signaling pathways at the intersection of metabolism and inflammation that contribute to diabetes. We also consider mechanisms through which the inflammatory response may be initiated and discuss the reasons for the inflammatory response in obesity. We put forth for consideration some hypotheses regarding important unanswered questions in the field and suggest a model for the integration of inflammatory and metabolic pathways in metabolic disease.

              Glycated albumin is a better glycemic indicator than glycated hemoglobin values in hemodialysis patients with diabetes: effect of anemia and erythropoietin injection.

              The significance of glycated albumin (GA), compared with casual plasma glucose (PG) and glycated hemoglobin (HbA(1c)), was evaluated as an indicator of the glycemic control state in hemodialysis (HD) patients with diabetes. The mean PG, GA, and HbA(1c) levels were 164.5 +/- 55.7 mg/dl, 22.5 +/- 7.5%, and 5.85 +/- 1.26%, respectively, in HD patients with diabetes (n = 538), which were increased by 51.5, 31.6, and 17.7%, respectively, compared with HD patients without diabetes (n = 828). HbA(1c) levels were significantly lower than simultaneous PG and GA values in those patients in comparison with the relationship among the three parameters in patients who had diabetes without renal dysfunction (n = 365), as reflected by the significantly more shallow slope of regression line between HbA(1c) and PG or GA. A significant negative correlation was found between GA and serum albumin (r = -0.131, P = 0.002) in HD patients with diabetes, whereas HbA(1c) correlated positively and negatively with hemoglobin (r = 0.090, P = 0.036) and weekly dose of erythropoietin injection (r = -0.159, P < 0.001), respectively. Although PG and GA did not differ significantly between HD patients with diabetes and with and without erythropoietin injection, HbA(1c) levels were significantly higher in patients without erythropoietin. Categorization of glycemic control into arbitrary quartile by HbA(1c) level led to better glycemic control in a significantly higher proportions of HD patients with diabetes than those assessed by GA. Multiple regression analysis demonstrated that the weekly dose of erythropoietin, in addition to PG, emerged as an independent factor associated with HbA(1c) in HD patients with diabetes, although PG but not albumin was an independent factor associated with GA. In summary, it is suggested that GA provides a significantly better measure to estimate glycemic control in HD patients with diabetes and that the assessment of glycemic control by HbA(1c) in these patients might lead to underestimation likely as a result of the increasing proportion of young erythrocyte by the use of erythropoietin.
