Calcium And Magnesium

BACKGROUND Magnesium is a potential modulator of seizure activity because of its ability to antagonize the excitatory calcium influx through N-methyl-D-aspartate (NMDA) receptor which is thought to play a role in many human forms of epilepsy. When the extracellular concentration of calcium ion falls below normal, the nervous system becomes more excitable, allowing easy initiation of action potentials. Consequently, hypocalcaemia causes seizures because of its action of increasing excitability in the brain. We wanted to estimate the serum concentration of calcium and magnesium in idiopathic epilepsy patients and its co-relation. METHODS 94 cases of idiopathic epilepsy with breakthrough seizures admitted to KIMS Hospital, Hubli, meeting the inclusion criteria were considered for the study which was for 2-years’ time period. It’s a single centred, time bound and cross sectional study. RESULTS Mean serum calcium was low 8.36 ± 0.45 mg / dL and mean serum magnesium was 1.79 ± 0.28 mg / dL. 64.9 % had total serum calcium less than 8.5 mg / dL and 44.7 % had serum magnesium of < 1.8 mg / dL. 35.1 % had both low calcium and magnesium. There was significant difference in mean serum calcium with respect to number of episodes. There was no significant difference in mean serum magnesium with respect to number of episodes. CONCLUSIONS Serum calcium and magnesium levels which play a role in seizure initiation should be measured in all idiopathic epilepsy patients with breakthrough seizures as a seizure trigger. Considering the role of calcium and magnesium in the pathophysiology of seizures and by evaluating the results from the present study, breakthrough seizure could be provoked by hypocalcaemia and hypomagnesemia. Hence they may be used for the treatment of intractable seizures. KEYWORDS Calcium, Magnesium, Idiopathic Epilepsy

Background: No previous study explored the association between serum calcium levels and dyslipidemia in children. This study aimed to explore this relationship in children, based on a multicenter cross-sectional study population in China.Methods: Cross-sectional data was derived from the Pediatric Reference Intervals in China (PRINCE) study conducted between 2017 and 2018 involving 5,252 males and 5,427 females with a mean age of 10.0 ± 4.6 years. Multivariable logistic regression models were applied to calculate odds ratios (ORs), with 95% confidence intervals (CIs), for dyslipidemia of each serum calcium level and albumin-corrected calcium levels, which were sorted into quartiles. The restricted cubic spline model was fitted for the dose-response analysis. An L-shaped dose-response relation between calcium levels and the probability of dyslipidemia was found after the adjustment for multiple potential confounding factors, p for non-linear &lt; 0.001.Results: Using the middle category of calcium level as the reference, multivariable-adjusted ORs and 95% CIs of the lowest and the highest quartile categories were 0.96 (0.82–1.12) and 1.29 (1.12–1.48), respectively, for total serum calcium levels and 1.06 (0.91–1.23) and 1.39 (1.21–1.60) for albumin-corrected calcium levels.Conclusions: Individuals with higher levels of serum calcium were associated with increased risk of dyslipidemia in a sample of a healthy Chinese pediatric population. The association between serum calcium levels and dyslipidemia needs to be examined prospectively in future studies.

Objective: To determine the frequency and compare serum calcium levels amongst extremely preterm and very preterm neonates. Study Design: Comparative cross sectional study. Place and Duration of Study: Combined Military Hospital, Multan Pakistan, from May to Oct 2018. Methodology: A total of 217 preterm neonates, born at Combined Military Hospital Multan up to the gestational age of 32 weeks completed from last menstrual period, were included in the study. They were divided in to two group’s i.e. very preterm and extremely preterm neonates. Those born between 28-32 weeks completed of gestation were categorized as severely preterm. Extremely preterm were those born between 24-28 weeks completed of gestation. Venous blood samples were acquired at approximately 36 hours after birth and total serum calcium levels were analyzed. Neonates having total serum calcium levels <7 mg/dL were declared as suffering from hypocalcaemia. Results: Out of 217 neonates, 117 (53.9%) were male while 100 (46.1%) were female. Mean gestational age was 30.98 ± 2.12 weeks while mean parity of the mothers was 2.82 ± 1.08 children. Mean birth weight was 1510.26 ± 142.38 grams. One hundred and seventeen (53.9%) of the preterm neonates suffered from hypocalcaemia with the mean total serum calcium level being 6.58 ± 0.86 mg/dL. Hypocalcaemia was more common in extremely preterm neonates compared to very preterm neonates (p<0.05). Conclusion: Hypocalcaemia is a frequent complication encountered in preterm neonates born between 24-32 weeks gestation. Within these neonates, the frequency of hypocalcaemia is higher in extremely preterm compared to severely preterm babies.

1. The renal handling of calcium and magnesium was studied in six patients with persistent hypomagnesaemia after cis-platinum treatment for testicular tumours. 2. In comparison with normal subjects, the patients showed hypomagnesaemia (mean 0.54 mmol/l), which was associated with a normal urinary magnesium excretion (mean 4.83 mmol/24 h). Urinary calcium excretion was significantly lower in the patients than in the normal subjects (mean 2.05 vs 5.15 mmol/24 h, respectively; P < 0.01), despite slightly higher total serum calcium levels (2.53 vs 2.38 mmol/l, respectively; P < 0.05). During magnesium chloride infusion, when serum magnesium levels were comparable in patients and controls, urinary calcium excretion remained lower in the patients, indicating that hypomagnesaemia was not the cause of the hypocalciuria. 3. Dietary magnesium supplementation resulted in a significant increase in the serum magnesium levels in the patients, while dietary magnesium deprivation resulted in a comparable decrease in urinary magnesium excretion in patients and controls (to 1.46 and 2.00 mmol/day, respectively), although the serum magnesium level fell further (to 0.46 mmol/l) in the patients. 4. The dissociation of renal calcium and magnesium excretion appears to be part of the intrinsic tubular defect caused by cis-platinum. This dissociation of urinary calcium and magnesium excretion, which resembles that seen in Bartter's syndrome, may result from a lesion in the distal convoluted tubule.

The oral contraceptive pill fulfills the great human need for birth control with unrivalled effectiveness. The pill can effectively prevent pregnancy and alleviate menstrual disorder when used correctly. Many biochemical profiles of women taking oral contraceptives are disturbed due to metabolic alterations induced by its hormone content. The study was carried out in the Department of Biochemistry, Mymensingh Medical College, Mymensingh, during the period of July 2016 to June 2017 to evaluate the status of serum calcium and magnesium in oral contraceptive user women. For this study, 120 age-matched women were selected and grouped as 60 oral contraceptive user women and 60 non-oral contraceptive user women. Data were analyzed with the help of SPSS version 21. Mean±SD level of serum calcium and magnesium were 9.50±0.70 mg/dl and 1.81±0.13 mg/dl in oral contraceptive user women, while in normal healthy women the levels were 9.03±1.69 mg/dl and 2.10±0.17 mg/dl respectively. No significant difference of serum calcium between two groups was observed (p>0.05). Serum magnesium significantly reduced in oral contraceptive users when compared with non-oral contraceptive users (p<0.001). The study showed no significant difference in serum calcium level in contraceptive group when compared with noncontraceptive user group and serum magnesium level was significantly reduced in oral contraceptive users when compared to normal healthy group.Bangladesh J Med Biochem 2017; 10(2): 64-68

BACKGROUND Role for macronutrient supplementation in preventing pre-eclampsia is now backed with evidence which is evolving rapidly. We wanted to study and compare serum calcium and serum magnesium levels in pre-eclamptic women and women with normal pregnancy. METHODS 30 women with normal pregnancy and 30 women with preeclampsia were included in the study. Their serum calcium and magnesium levels were estimated using colorimetry. RESULTS Serum calcium levels in normotensive patients was found to be 9.3 ± 0.95 mg / dL and in preeclamptic patients, it was 8.3 ± 0.85 mg / dL. Serum magnesium levels were found to be 1.94 ± 0.24 mg / dL and 1.57 ± 0.125 mg / dL in normal and pre-eclamptic women respectively. These values were affected by age, parity, BMI, socio-economic status, and nutrition before and during pregnancy. CONCLUSIONS Low values of maternal serum calcium along with magnesium are related to preeclampsia which might have an association in this disease. We also realised that evaluation of base-line levels of serum calcium and magnesium are necessary during early pregnancy. Constant monitoring of blood pressure is also essential. Adequate intake of macronutrients is essential for maintaining health of both mother and child. Hence, measurable and realistic efforts must be made along these lines. Nutrition is a key concern in pregnant women and is pivotal in ensuring health in this vulnerable group. KEYWORDS Pre-Eclampsia, Serum Calcium, Serum Magnesium, Pregnancy, Macronutrients

Medical analysis laboratory must establish its own reference intervals depending on the facilities they are working with, the working substances and protocols. These reference intervals must be obtained depending on age groups in order to accurately interpret the results of the analyzes performed. The study is a retrospective one using 3217 data from the electronic archive of the S.C. Vladutiu&Garabedian S.R.L. Clinic in Medias. Total serum calcium was determined by the colorimetric method on the Konelab analyzer. Processing of the collected data was done using the Hoffmann method, considering 5% up to 95% of the values in the database, the values being randomly selected. For comparison, data from the literature was used. In children under 1 year old, it was not possible to calculate the reference intervals since data was insufficient. In the other age groups, reference intervals obtained in the current study were similar to the studied literature. Reference intervals established for calcium can provide important guidance for the reasonable supplementation of this essential element in children.

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.
