Background Hyperbilirubinemia is one of the most common problems in newborns. Severe hyperbilirubinemia, known as kernicterus, can suppress O2 consumption and oxidative phosphorylation, as well as damage brain cells, resulting in neuronal dysfunction and encephalopathy. Phototherapy is a common therapy for neonatal hyperbilirubinemia, but may rarely lead to the adverse effect of hypocalcemia. Objective To investigate serum calcium levels in full term neonates with hyperbilirubinemia, before and after phototherapy. Methods This cohort study compared total serum calcium level before and after phototherapy in full term neonates with hyperbilirubinemia. Subjects were full term neonates aged 2-14 days with high total serum bilirubin levels, according to the Bhutani curve, and were treated with phototherapy at Sanglah Hospital, Denpasar, Bali, Indonesia. Paired T-test was used to compare serum calcium levels before and after phototherapy. Results There were 35 subjects in this study. Paired T-test revealed that subjects’ serum calcium significantly decreased after phototherapy [before: 9.47 mg/dL vs. after: 9.23 mg/dL; mean difference 0.24; (95%CI 0.03 to 0.46; P=0.025)]. None of our subjects had hypocalcemia after phototherapy. Conclusion Full term neonates with hyperbilirubinemia have reduced serum calcium levels after phototherapy.

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: Pancreatitis is an inflammatory condition that affects the pancreas and may also affect other tissues or distant organ. In this study our aim is to see if blood calcium level can be used as a prognostic marker in determining the severity of acute pancreatitis because hypocalcaemia is linked to higher mortality and hospitalization. Method: A retrospective study was conducted in the medical records department of a tertiary care health facility. A total of 75 participants were included in the research. .demographic details of all patients were collected .Patients above 18 years who presented with of epigastric pain, pre-Diagnosed gallstones, alcoholism were included int this study. The lowest total calcium levels were collected in order to examine total calcium as a predictive factor for severity. All of these information were collected and analyzed to get the appropriate findings. Results: A total of 75 patients were included in the research. The age of patients in each severity grade did not differ significantly (p value>0.05). The gender distribution of the two groups did not differ. (P >0.05). For mild and severe acute pancreatitis, mean total calcium levels were 7.98 and 6.67, respectively, which was statistically significant (p< 0.05). Conclusion: The total serum calcium level is a useful indicator for assessing  pancreatitis.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease and hypocomplementemia signifies disease activity. Several studies have shown that calcium may help maintain optimum function of immune system and metabolism in SLE. The aim of our study was to analyze the relationship between total serum calcium level and SLE activity. A total of 66 patients with SLE and 214 healthy controls were included in this study. Our results showed lower serum levels of calcium ( P < .001), complement C3 ( P < .001), complement C4 ( P < .001), and albumin ( P < .001) in patients with SLE. A negative correlation was found between serum calcium level and systemic lupus erythematosus disease activity index (SLEDAI) rating ( r = −0.394, P = .001). Additionally, serum level of calcium was positively correlated with serum complement C3 level ( r = 0.366, P = .003) in patients with SLE, while no such correlation was found between serum calcium level and complement C4 ( r = −0.190, P = .126). Likewise, patients with SLE with normal serum calcium level showed higher complement C3 level ( P < .01) than that of patients with low serum calcium level. Overall, the results displayed that patients with SLE have lower serum calcium level compared to healthy controls, and the serum calcium level is positively correlated with SLEDAI rating and serum complement C3 level in patients with SLE. In conclusion, the total serum calcium level is negatively correlated with SLE disease activity.

Background: To study the occurrence of hypocalcaemia in neonates with physiological unconjugated hyperbilirubinemia after 48 hours of phototherapy or at the end of phototherapy, in case duration of phototherapy was less than 48 hours.Methods: This prospective study was conducted on 100 term neonates (61 males and 39 females) admitted to Neonatal intensive care unit of Teerthankar Mahaveer Medical College, Moradabad with unconjugated hyperbilirubinemia and requiring phototherapy. Total Serum bilirubin levels and serum calcium levels were checked before and after phototherapy. Neonates were assessed for clinical features of hypocalcemia i.e. jitteriness, irritability/excitability, lethargy and convulsions.Results: After phototherapy, there was hypocalcemia in 35.0% neonates. The difference between pre and post phototherapy serum calcium levels were found to be statistically significant (p <0.001). 2.86% of neonates developed jitteriness among those who had hypocalcemia. Hypocalcemia was more in subjects who received phototherapy for longer duration.Conclusions: Hypocalcaemia is a common complication of phototherapy. Therefore, calcium supplementation should be done in all neonates undergoing phototherapy.

Background Antiepileptic drugs (AEDs) may affect calcium metabolism through several mechanisms. Much evidence has confirmed that carbamazepine and valproic acid, as the most widely used AEDs in epileptic children, leads to decreased serum calcium levels. This effect was suggested to be time and dose dependent. However, correlations between AEDs and calcium levels in Indonesian epileptic children have not been well studied.Objective To investigate possible correlations between total calcium levels and durations of therapy as well as doses of carbamazepine and valproic acid.Methods This analytical, cross-sectional study was performed from March to May 2015 in the Neuropediatric Outpatient Ward of Mohammad Hoesin Hospital, Palembang, South Sumatera. A total of 60 epileptic children taking carbamazepine and or valproic acid monotherapy were included and grouped accordingly. A single blood test was done for every participant to measure total serum calcium level. Correlation between daily dose or duration of AED with calcium level was assess using the Spearman-rho test.Results The mean total serum calcium levels in the carbamazepine and valproic acid groups were 9.48 (SD 0.83) mg/dL and 9.58 (SD 0.63) mg/dL, respectively. There was a statistically significant moderate correlation between the duration of carbamazepine therapy and total calcium level (r = 0.36; P=0.001). The cut-off point for duration of therapy was 23 months. There were no significant correlations between total calcium level and mean daily carbamazepine dose, nor between total calcium level and duration and dose of valproic acid therapy.Conclusion Longer duration of carbamazepine therapy is associated with low total serum calcium level, but carbamazepine dose is not. In addition, duration and dose of valproic acid are not associated with low total serum calcium level.

Background: Hypocalcemia is a frequently observed clinical and laboratory abnormality in neonates with risk factors such as prematurity, infant of diabetic mothers and perinatal asphyxia. Hypocalcemia can be asymptomatic or can cause apnoea, seizures, jitteriness, stridor, cardiac abnormalities. Clinically as calcium levels are maintained within narrow ranges. It is therefore imperative to measure and correct any deficit at the earliest. Unfortunately, total serum calcium level correlates poorly with ionized calcium level. Measurement of ionized calcium is both time consuming and expensive and therefore the need for more rapid, inexpensive and non-invasive method for screening at risk-neonates. Serum calcium levels are known to affect the duration of the QoTc interval. Therefore establishing a good correlation between serum/ionized calcium levels and QoTc will validate ECG as a reliable marker of hypocalcemia. Objective was to find correlation between QoTc interval and serum calcium levels in sick neonates.Methods: Total 730 infants were for serum total calcium and ionized calcium levels. Off these 142 infants with hypocalcemia, 29 infants were excluded based on exclusion criteria. The remaining 113 neonates were subjected to three cycles of ECG measurement before correction of calcium and were taken as cases. QoTc intervals were measured and were correlated with corresponding serum total calcium and ionized calcium levels.Results: In this study, a moderate negative or downhill correlation was found between total serum calcium QoT (r = -0.694 and p = <0.001) and QoTc (r = -0.680 and p = <0.001). The ionized calcium levels were found to have strong negative or downhill correlation with QoT (r = -0.837 and p = <0.001), QoTc (r = -0.819 and p = <0.001). All these correlations were found to be statistically significant with p<0.05.Conclusions: QoTc interval can be used as a surrogate marker for blood total or ionized calcium levels.

Introduction: The most prevalent anomalous physical finding during the first week of life is neonatal hyperbilirubinemia (NNH). It is estimated that more than two thirds of newborn babies have acquired clinical jaundice. It was also discovered that in the unconjugated hyperbilirubinemia of most neonates represents a common or exaggerated physiological syndrome. The physical immaturity of infants to handle increased production of bilirubin is referred to as Jaundice. This becomes potentially neurotoxic if severe unconjugated hyperbilirubinemia is left untreated. One of the routine strategies for treating hyperbilirubinemia is known as phototherapy. However it is not a harmless interference. This can produce negative results, such as dehydration, temperature volatility, blood flow redistribution, genotoxicity, rashes on the skin, loose skin, stools, damage to retinas, hypocalcemia and bronze baby syndrome. One of the lesser known but which has a potential adverse effect of phototherapy is hypocalcemia. A total serum calcium concentration of < 7 mg / dl or ionised calcium concentration < 4mg / dl (< 1mol / L) is classified as neonatal hypocalcemia. Hypocalcemia increases the permeability of cells to sodium ions and increases the excitability of cell membranes. Material & Methods: 60 full term neonates were included in present cross sectional study who was admitted to Neonatal Intensive Care Unit (NICU). Full term neonates who completed 37 weeks of gestation with unconjugated hyperbilirubinemia who require phototherapy. Under the normal protocol, traditional phototherapy equipment containing four blue light fluorescent lamps with wavelengths of 410-470 nm was mounted at a distance of 25-35 cm from the skin surface of neonates with entirely covered eyes and genitals. At 15μW / cm2 /nm at the level of the infant's skin, the irradiance during phototherapy was assessed and maintained consistently. Results: Among 60 neonates included in this study there were 27 (45%) male whereas 33 (55%) female neonates. In present study the mean levels of serum calcium before phototherapy was 9.21 with standard deviation of 0.83 while the serum calcium levels after phototherapy were 8.36 with standard deviation of 0.78. There was a statistically significant difference between serum mean calcium levels before and after phototherapy (p=0.001). Conclusion: A major issue is phototherapy induced hypocalcemia. Before beginning and during phototherapy for neonatal jaundice and close monitoring of neonates for signs of hypocalcemia, careful calcium status calculation should be carried out.. After phototherapy, there is a substantial reduction in the amount of serum calcium, but the risk of hypocalcemia in stable full-term neonates is minimal.
