Abstract
- Para verificar a variabilidade do controle glicêmico em um estudo não controlado de diabéticos durante um ano de acompanhamento, nós avaliamos retrospectivamente 113 pacientes diabéticos. Com os valores das HBA1c (hemoglobina glicada) dosadas em 1998 calculamos um índice de controle que foi associado à idade, duração do diabetes, IMC e dose de insulina. A HBA1c foi maior em pacientes DM1 do que DM2, respectivamente [7,9 (4,4-13,3) vs. 7,0 (4,4-13,4)%; p= 0,007]. Nos 90 pacientes com no mínimo duas HBA1c, 68 (75,6%) mantiveram o controle: 51 (76,1%) em bom, 8 (11,1%) em regular e 9 (11,9%) em péssimo controle. Nenhum manteve todas as HBA1c na faixa da normalidade, sendo que 26 pacientes (28,9%) tiveram pelo menos uma HBA1c normal. No grupo geral, 44 pacientes (48,9%) apresentaram aumento da HBA1c, 41 (45,6%) diminuição e 5 pacientes (5,6%) mantiveram o mesmo valor, sem diferença entre DM1 e DM2 (p= 0,77). Observamos diferença na HBA1c e tempo de duração de diabetes entre os pacientes com DM2 que tratavam com dieta, hipoglicemiante oral, terapia combinada e monoterapia com insulina, respectivamente (5,4±0,5 vs. 6,3±1,3 vs. 7,6±1,4 vs. 8,4±2,0%; p= 0,001) e (8,5±9,9 vs. 5,3±4,2 vs. 14,1±9,6 vs. 16,9±8,1 anos; p= 0,003). O coeficiente de variação intraindividual da HBA1c foi de 11,6±7,4% (p= 0,0000), sendo de 12,8±7,6% (p= 0,0000) em DM1 e 10,4±7,2% em DM2 (p= 0,0000) sem diferença entre ambos. Concluímos que em nossa amostra a maioria dos pacientes manteve um bom controle apesar da variabilidade intraindividual e da dificuldade em normalizar os níveis de HBA1c. To evaluate the variability of glicemic control in diabetic patients followed during one year, we conducted a retrospective study in which the record data of 113 diabetic patients were analyzed. The value of HBA1c (glycated hemoglobin) measured during a year were registered and an index of glicemic control was calculated. This index was associated with duration of diabetes, BMI and dose of insulin. HBA1c were higher in type 1 diabetes than type 2, respectively, [7.9 (4.4-13.3) vs. 7.0 (4.4-13.4)%; p= 0.007]. In 90 patients with at least two HBA1c measurements, 68 (75.6%) had no change in glicemic control: 51 (76.1%) had good, 8 (11.1%) regular and 9 (11.9%) poor control. None of them sustained all the HBA1c in the normal range: 26 (28.9%) had at least one normal HBA1c value. In general group, 44 patients (48.9%) showed increase, 41 (45.6%) decreased and 5 (5.6%) remained with the same level of HBA1c, without difference between DM1 and DM2 (p= 0,77). A difference in HBA1c and diabetes duration among patients with DM2 treated with diet, oral hipoglycemic agents, combined therapy and monotherapy with insulin, was noted respectively (5.4±0.5 vs. 6.3±1.3 vs. 7.6±1.4 vs. 8.4±2.0%; p= 0.001) and (8.5±9.9 vs. 5.3±4.2 vs. 14.1±9.6 vs. 16.9±8.1 years; p= 0,003). The intraindividual coefficient of variation of HBA1c was 11.6±7.4% (p= 0.0000) being 12.8±7.6 (p= 0.0000) in type 1 and 10.4±7.2% in type 2 (p= 0.0000) without difference between both groups. In conclusion: the majority of the patients in our study maintained a good control despite the intraindividual variability of HBA1c and the difficulty to keeping it in the normal range.
