| Abstract: | Objective: The aim of this study was to evaluate maternal neutrophil gelatinase-asssociated lipocalin (NGAL) levels and fetal renal artery (fRA) Doppler flow indices in pregnant women fasting in Ramadan in respect of dehydration in long hot summer days as a marker of hypoperfusion and early renal injury.Methods: A cross-sectional observational study was carried out at a University Hospital. Fasting pregnant women and non-fasting age, gravidity and gestational age-matched women were evaluated for hematologic, blood biochemistry and urine parameters in the first and fourth weeks of the Ramadan. Umbilical artery and fRA Doppler flows were studied in each evaluation.Results: Blood urea nitrogen, potassium and hematocrit levels, blood and urine NGAL levels were significantly higher, and fRA Doppler indices increased in fasting women (p?p?>?0.05).Conclusions: Adequate maternal vascular volume is essential for the maintenance of healthy pregnancy. Fasting during the long and hot summer days leads to fluid deprivation and dehydration which was found to be related to subclinical maternal renal dysfunction and increased fRA Doppler indices. |
