RESUMO
OBJECTIVE: To evaluate the alternative parameters to monitor glycemia in pregnant women with diabetes studying the relationship between fructosamine testing and self monitoring of blood glucose in pregnant women with diabetes. MATERIALS AND METHODS: Serum fructosamine levels and the self monitoring of blood glucose over 14 days before the collection of fructosamine were evaluated in 47 diabetic pregnant women. RESULTS: Seventy-one fructosamine levels and 2,238 glucose measurements (CGs) were analysed. Levels of fructosamine correlated with high blood glucose index (HBGI) and the standard deviation of glycemias (r = 0.28; p = 0.021 and r = 0.26; p = 0.03, respectively). The comparison between the mothers of the newborns with appropriated or large birthweight and those who gave birth to small newborns for their gestational age (SGA) showed that the latter had a lower glycemic mean (105 vs. 114 and 119 mg/dL), a higher low blood glucose index (5.8 vs. 1.3 and 0.7) and a higher percentage of hyperglycemias (11 vs. 0 and 0%) even when the fructosamine falls within the reference values (242 vs. 218 and 213 µmol/l). CONCLUSION: The levels of fructosamine can be used as further parameter to aid self monitoring of blood glucose to evaluate hyperglycemias and glycemic variability, however, this can underestimate hypoglycemias in pregnant women carrying small-for-gestational age fetuses.

Objetivo Avaliar parâmetros alternativos para monitorar a glicemia em portadoras de diabetes na gestação estudando a relação entre a frutosamina e a automonitoração em gestantes portadoras de diabetes. Materiais e métodos: A frutosamina sérica e os parâmetros da automonitoração nos 14 dias que antecederam a coleta da frutosamina foram avaliados em 47 gestantes portadoras de diabetes. Resultados Setenta e uma determinações de frutosamina e 2.238 glicemias capilares (GCs) foram analisadas. A frutosamina correlacionou-se com o índice de excursões hiperglicêmicas (HBGI) e o desvio-padrão das glicemias (r = 0,28; p = 0,021 e r = 0,26; p = 0,03, respectivamente). A comparação entre as mães dos neonatos com peso adequado ou grandes ao nascer com as genitoras que tiveram neonatos pequenos para a idade gestacional (PIG) revelou que estas tiveram menor média glicêmica (105 vs. 114 e 119 mg/dL), maior índice de excursões hipoglicêmicas (5,8 vs. 1,3 e 0,7) e maior percentual de hipoglicemias (11 vs. 0 e 0%) mesmo com frutosamina dentro dos valores de referência (242 vs. 218 e 213 μmol/l). Conclusão A frutosamina pode ser utilizada como parâmetro auxiliar à automonitoração para avaliação de hiperglicemias e variabilidade glicêmica, entretanto pode subestimar hipoglicemias em gestantes com fetos PIG. .
