RESUMO
AIMS OF THE STUDY: We describe the impact of different forms of dysglycemia on maternal and neonatal health. This research is a part of the PEARL-Peristat Maternal and newborn registry, funded by Qatar National Research Fund (QNRF) Doha, Qatar. METHODS: A population-based retrospective data analysis of 12,255 women with singleton pregnancies screened during the year 2016-2017, of which 3,027 women were identified with gestation diabetes mellitus (GDM) during pregnancy and 233 were diabetic before pregnancy. Data on maternal outcome was collected from the PEARL-Peristat Maternal and newborn registry. RESULTS: The prevalence of GDM and diabetes mellitus (DM) was 24.7 % and 1.9%, respectively. 55% of DM, 38% of GDM and 25.6% of controls were obese (p<0.001). 71% of pregnant women with DM and 57.8% of those with GDM were older than 30 years versus 44.2% of controls. Pregnant women with DM or GDM had higher prevalence of hypertension versus normal controls (9.9%, 5.5% and 3.5%, respectively; p<0.001). Among women with vaginal deliveries, the proportion of women with induction of labor was significantly higher in the DM and GDM compared to control subjects (33.9%, 26.5% and 12.4%, respectively; p<0.001). The number of women who underwent Cesarean section was significantly higher in the DM and GDM groups versus normal controls (51.9%, 36.8%, and 28.5%, respectively; p<0.001). Preterm delivery was significantly higher in women with DM and GDM (13.7% and 9%, respectively versus normal women (6.4%); p<0.001). Babies of DM and GDM had significantly higher occurrence of respiratory distress (RDS) or transient tachypnea (TTS): 9% and 5.8 % versus normal controls (4.8%). Macrosomia was more prevalent in babies of DM (6.4%) and GDM (6.8%) compared to controls (5%) (p: <0.001). Significant hypoglycemic episodes occurred more frequently in babies of DM and GDM women (11.2% and 3%, respectively) versus controls (0.6%) (p: <0.001. Infants of DM and GDM mothers required more treatments of phototherapy (9.4% and 8.9%, respectively) versus those born to normal women (7.2%) (p: 0.006). The prevalence of congenital anomalies and neonatal death did not differ between the groups. CONCLUSIONS: Despite the improvement in the prenatal diagnosis and management of dysglycemia, there is still a higher prevalence of prematurity, macrosomia, and hypoglycemia in infants of mothers with DM and GDM. Measurements to reduce obesity and control dysglycemia in women during the childbearing period are highly required to prevent the still higher morbidity during pregnancy.

INTRODUCTION: The Clinical and radiological manifestations of newborns with severe VDD have not been studied well. MATERIALS AND METHODS: We studied the clinical, biochemical, and radiological manifestations of 10 full-term (FT) newborns (6: M, 4: F) infant presented to with symptomatic hypocalcemia (seizure) secondary to vitamin D deficiency (VDD) during the first 10 days of life are described. All were exclusively breastfed since birth. All their mothers have low 25 hydroxy vitamin D (25OHD) level <10 ng/mL and were not taking vitamin supplements during pregnancy. RESULTS: FT newborns with hypocalcemia secondary to VDD presented with generalized convulsions (10/10) and craniotabes (8/10), but none had rachitic chest rosaries or joint broadening. Cranial ultrasonographic evaluation was normal. Serum 25OHD concentrations were low in these newborns (13.2 ± 3.8 ng/mL) and their mothers (8.1 ± 1.5 ng/mL). A total of 60% of them had increased parathormone (PTH) concentrations (>60 ng/mL) and 60% had decreased magnesium (Mg) concentrations (<0.7 mmol/L). Their alkaline phosphatase (ALP) concentrations were significantly higher than normal newborns. All other laboratory results (liver function tests, urea and electrolytes, C reactive protein, lumbar puncture, blood culture, and lactate) were normal. In all patients, seizures ceased within 2 days of starting treatment with alphacalcidol and calcium. Radiological manifestations included metaphyseal band of relative lucency (osteopenia), just under the line of provisional calcification, within distal radius (7/10), femur (4/10), and tibia (3/10), mild cupping and haziness of distal radius (2/10). DISCUSSION: Newborns with VDD had significantly lower serum calcium, ALP and PTH and higher phosphate concentrations, compared to older infants with VDD rickets. In newborns with VDD, serum calcium levels were correlated significantly with 25OHD (r = 0.597, P < 0.001), Mg concentrations (r = 0.436, P < 0.001) and negatively with ALP concentrations (r = -0.451, P < 0.001). Serum PTH concentrations were correlated significantly with serum Mg (r = 0.78, P < 0.0001) but not with serum calcium (r = -0.103, P = 0.3) or 25OHD (r = -0.03, P = 0.7) concentrations. CONCLUSION: The clinical, biochemical, and radiological manifestations of VDD in newborns indicate that they are less adapted to VDD compared to older infants. VD supplementation for mothers and newborns should be considered to avoid short-term complications of VDD in the neonatal period and on the growing infants especially in countries with high prevalence of VDD.
