Abstract Background Preeclampsia is a well-known cause of maternal mortality and morbidity in Ethiopia. The exact pathophysiology has not been fully understood. Calcium and magnesium deficiencies have been given emphasis to play roles in the pathophysiology. Although evidence is abundant, they are equivocal. The study aimed to see the association of dietary calcium intake, serum total calcium level and ionized calcium level with preeclampsia. It also evaluated the association between dietary calcium intake and serum calcium levels. Materials and methods An unmatched case–control study was conducted in Gandhi Memorial, Tikur Anbessa, and Zewditu Memorial Hospitals, all in Addis Ababa, between October to December, 2019. Cases were 42 women with preeclampsia and controls were 42 normotensive women. The medical and obstetric history was gathered using a structured questionnaire and the dietary calcium intake information using a 24-h dietary recall. The serum levels of total serum calcium and ionized (free) calcium were measured using an inductively coupled mass spectrophotometer. Bivariate and multivariate logistic regression and Pearson correlation test were utilized during data analysis. Results In comparison with controls, women with preeclampsia had lower mean (± 1SD) levels of ionized calcium level (1.1 mmol/l ± 0.11), total serum calcium level (1.99 mmol/l ± 0.35) and lower median (IQR) dietary calcium intake (704 mg/24 h,458–1183). The odds of having preeclampsia was almost eight times greater in those participants with low serum ionized calcium level (OR 7.5, 95% CI 2.388–23.608) and three times higher in those with low total serum calcium level (OR 3.0, 95% CI 1.024–9.370). Low dietary calcium intake also showed statistically significant association with preeclampsia (OR 3.4, 95% CI 1.092 -10.723). Serum ionized calcium level and total serum calcium level showed positive correlation of moderate strength (p = 0.004, r = 0.307), but no correlation was found between dietary calcium intake with both forms of serum calcium levels. Conclusion This study showed significant association between low dietary calcium intake and low serum calcium levels with preeclampsia, hence this can be used as a supportive local evidence for the current context-specific recommendation of calcium supplementation in societies with low-dietary calcium consumption in an attempt to prevent preeclampsia, therefore implementation study should be considered in Ethiopia to look for the feasibility of routine supplementation.

Background: Nutritional status in relation to selected biochemical parameters and also nutrient intakes in the pre-eclampsia and eclampsia was assessed in 52 patients and compared with that of 52 normal pregnant (NP) women. Serum calcium, ascorbic acid and blood Hb levels in the pre-eclamptic and eclamptic patients were significantly lower than the values of NP women. By unpaired t-test demonstrated in our study, the serum calcium, ascorbic acid and blood Haemoglobin (Hb) level were highly significantly different but not correlated with each other when compared among these groups. However, total statistical analysis revealed that among all the factors studied serum calcium level, ascorbic acid level and blood Hb level have effect on nutritional status of pre-eclampsia and eclampsia.DOI: http://dx.doi.org/10.3329/bjnut.v24i0.14032 Bangladesh J.

Background: Calcium requirement increases during pregnancy, thereby increasing the chances of developing hypocalcaemia. Hypocalcaemia may be associated with pregnancy-related complications. Therefore, we planned this study to estimate the prevalence of hypocalcaemia among pregnant women attending secondary care hospital, and to study the association between hypocalcaemia and pregnancy outcomes. Materials and Methods: This study was conducted in a secondary level hospital at Ballabgarh, district Faridabad, Haryana, India. Consecutive pregnant women with gestation period more than 28 weeks were enrolled. Dietary calcium intake was ascertained using 24-hour dietary recall method. Serum calcium estimation was done by Biolis 24i auto analyser. Outcome of pregnancy (preterm delivery, low birth weight (LBW) babies, and neonatal mortality) was assessed telephonically 3 months after the enrolment. Results: A total of 696 pregnant women were enrolled in the study. Mean (SD) dietary calcium intake and serum calcium level was 796.4 (360.4) mg/day and 9.56 (0.94) mg/dl respectively. Prevalence (95% CI) of hypocalcaemia was 23.9% (20.8 – 27.2%). Serum total calcium level was not associated with dietary calcium intake (p-value – 0.36). Mean serum calcium level was significantly lower in mothers who had LBW babies. Pre-eclampsia, preterm delivery, and neonatal mortality were not associated with serum calcium level. Conclusion: Serum calcium level may not be related to dietary calcium level. Hence, the current recommendation of calcium supplementation during antenatal period appears to be inconclusive among our study population.

ABSTRACT In addition to the previously described permeability disturbance in the blood aqueous barrier of the eye, measured as an increase of the aqueous flare, a series of transitory systemic effects have been recorded following the subcutaneous injection of synthetic α-MSH: marked increase of the free fatty acids in plasma, decrease in the serum calcium level, decrease in the blood pressure, increase in the skin temperature, increased frequency and diminished amplitude of respiration, presence of slow waves in the EEG. There is a correlation between the magnitude of the aqueous flare increase and the increase of free fatty acids in plasma and also between the aqueous flare and the minimum serum calcium level.

Objective: To determine the frequency of hypocalcemia in neonates with unconjugated hyperbilirubinemia receivingphototherapy.Study design and setting: Cross sectional study conducted at neonatal intensive care unit, King Abdullah Teaching Hospital,Mansehra for one year from December 2017 to November 2018.Methodology: Total 213 full term stable neonates of either gender with jaundice were studied in this study. Out of which,143 with unconjugated hyperbilirubinemia were exposed to phototherapy while 70 neonates with exaggerated physiologicalhyperbilirubinemia taken as control were not exposed to phototherapy. Serum calcium level was determined through bloodtest before and after 24 hours of phototherapy. SPSS version 22 was used to analyze the data. Frequency and percentageswere used to describe categorical variables like gender and hypocalcemia. Hypocalcemia was stratified by age and genderto see effect modifiers. Post stratified chi-square test was applied in which p value = 0.05 was considered as significancevalue.Results: In study group, 143 neonates who received phototherapy had mean age of 7 days ± 2.62 SD. Total 65% neonateswere male and 35% neonates were female. Mean serum calcium level of neonates before and after provision of phototherapywas 9.28 mg/dl ± 0.23 and 8.54 mg/dl ± 0.68 respectively, which is statistically significant. The frequency of hypocalcemiawas 40% in neonates with unconjugated hyperbilirubinemia after 24 hours of phototherapy.Conclusion: Hypocalcemia is an important complication in neonates with unconjugated hyperbilirubinemia after continuousphototherapy. Hypocalcemia has clinical impact and adds to morbidity, and if left untreated, can lead to mortality.
