ABSTRACT
To study the disturbances of biochemical parameters which make it possible to evaluate the nutritional state during the cystic fibrosis. Prospective study about 13 cases hospitalized over a 7 months period, whose age varies between 2 months and 12 years and adressed for a suspicion of cystic fibrosis. For all the patients we made a clinical collection of the data and a biochemical study. Hypoprotidemia [protidemia < 60 g/l] was noted in 6 cases. Three cases presented a hypocalcaemia [calcemia < 2.20 mmol/l]. A hypomagnesaemia [magnesemia < 0.70 mmol/L] was observed in 2 cases. The totality of the patients presented zinc concentrations lower than the normal value. Iron concentrations lower than the normal [11- 24 mmol/l] was noted in 5 cases. Four patients [4/13] presented a concentration of iron between 11.2 and 20 mmol/l, whereas a high concentration [32.3 mmol/l] was noted in only one case [7.7%]. The study of the biochemical parameters allowed to evaluate the variation of some trace elements in cystic fibrosis and their consequence on the nutritional state of the patients, which constitutes an essential element for the assessment of these patients
ABSTRACT
The delivery of a large baby may indicate that the mother had abnormal glucose tolerance during pregnancy. Glycosylated hemoglobin [HbA1c] concentration might be expected to identify women who had high blood glucose concentration before delivery. The aim of this study was to identify retrospectively, gestational diabetes in mothers of large baby and determine the HbA1c cutoff value. HbA1 was measured in 216 patients within the first three days of postpartum: 100 had large babies: weighing over than 4000g and 113 had normal-sized babies [control group]. We exclude mothers who had preterm, hypotrophy baby, stillborn, and diabetic mothers. The mean concentration of HbA1c was significantly higher in group with large babies than in group control [6.17%+ 085 vs 5.17+0.571=9.78 p<0.001]. The value of HbA1c=5.85%, evaluated by ROC curve, was considered as risk factor of macrosomia and then gestational diabetes. 83.5%of mothers with large babies had HbA1c 7 5.85 vs 7.8%of those with normal sized babies [p<0.0001]. No other significant differences were found between the two groups in other parameters. HbA1 c level may be of value as a postpartum screen for unrecognized diabetes and may help discriminate between a constitutionally large but otherwise normal newborn and a large infant of a diabetic mother. HbA1c measurements should be obtained in women with large babies, and, if upper than cutoff value found by curve ROC: 5.85%, maternal and fetal surveillance is recommended
