Background/Aims: As shown in the China Health and Nutrition Survey, serum magnesium is associated with anemia. However, the roles of magnesium in anemia and erythropoietin (EPO) responsiveness remain unclear in maintenance hemodialysis (MHD) patients. This study aims to investigate the level of serum magnesium and its relationship with EPO responsiveness in MHD patients. Methods: A total of 307 MHD patients were recruited for this survey. Laboratory data and anthropometrics were collected. EPO responsiveness was evaluated by the erythropoietin resistance index (ERI). The subjects were divided into 3 groups according to serum magnesium concentrations (group A, the lowest tertile; group B, the middle tertiles; and group C, the highest tertile). Multivariate logistic regressions were conducted to evaluate the factors that may be associated with EPO responsiveness. Results: The mean serum magnesium level was significantly higher than normal levels in MHD patients, while no hypomagnesemia was observed. A multivariate logistic regression model revealed that high-sensitivity C-reactive protein, intact parathyroid hormone, serum albumin, and magnesium levels were correlated with a high ERI. The OR of a high ERI was found to be 2.57 (95% CI 1.330–4.975, p = 0.005) for group A and 1.66 (95% CI 0.878––3.140, p > 0.05) for group B compared with the OR for group C. Conclusion: Serum magnesium levels were higher than normal levels in MHD patients. A high serum magnesium level was correlated with good EPO responsiveness and was therefore suggested to be a protective factor for EPO hyporesponsiveness.

Background: Acute Myocardial Infarction is the leading cause of morbidity and mortality throughout the world. Its prevalence among developing countries has increased significantly over the past two decades. Acute myocardial infarction is associated with electrolyte imbalance most commonly hypomagnesemia and hypokalaemia. Both are associated with ventricular arrhythmia which can lead to increase hospital mortality and morbidity. Objectives: To find out association of hypomagnesemia with ventricular arrhythmia in patients with acute myocardial infarction. Methods: Patients with acute myocardial infarction admitted in the department of Cardiology, DMCH, within the study period and who fulfilled the inclusion and exclusion criteria were taken as study sample. Informed consent was taken from all patients and then the patients were evaluated by detailed history, clinical examination and relevant investigations. Serum magnesium level was measured after admission. The sample population was Grouped into Group A(Acute myocardial infarction with normal serum magnesium) and Group B(Acute myocardial infarction with hypomagnesemia). Patients were followed up regularly till discharge or death for evidence of ventricular arrhythmia. Then the obtained data was analysed with SPSS 22.0. Results: Among 110 patients of Acute MI, 44 patients were in Group A who had plasma magnesium level e”0.7 mmol/ l and 66 patients were in Group B who had plasma magnesium level <0.7 mmol/l. Incidence of hypoagnesemia was 60% and more common in male. Male vs female percentage of hypomagnesemia were 61% vs 39%. Mean age was 54.16±11.72 yrs vs 57.52±10.59 yrs in group A vs group B. On admission serum magnesium level was 0.9218 vs 0.523 mmol/L( group A vs group B). The study showed that group B patients were more haemodynamically unstable and mean SBP and DBP were found 89.39±19.93 and 60.67±11.56 mm-Hg respectively. Troponin I was markedly increased in group B than A (i.e 4.7±1.79 vs 14.6±4.3 vs ng/ml). Adverse cardiac events such as cardiogenic shock (group A vs group B = 11.36% vs 28.27%) and ventricular arrhythmias(group A vs group B = 34% vs 72.73%) were also higher in group B than group A. Mean hospital stay for group B patient was higher than group A(6.78±0.85 vs 5.31±0.35 days). The study result showed that ventricular arrhythmia is negatively correlated with serum magnesium and the correlation coefficient was - 0.541. It also showed that serum Magnesium is positively correlated with Potassium(r= 0.831, p<0.01) and Calcium(r= 0.902, p<0.001). Multiple logistic regression analysis showed that hypomagnesemia is an independent risk factor for ventricular arrhythmia. Conclusions: This study showed that in patients with acute myocardial infarction, hypomagnesemia is common and it is significantly associated with ventricular arrhythmia. So the presence of hypomagnesemia should alert the physicians to adopt corrective measures as it increases both mortality and morbidity. Bangladesh Heart Journal 2020; 35(1) : 39-46

Background: Serum magnesium level is an important electrolytes for the maintenance of haemodynamic of the body. Objective: The purpose of the present study was to correlate the serum magnesium level and blood sugar status. Methodology: This cross sectional study was carried out in the Department of Medicine at Shaheed Suhrawardy Medical College Hospital, Dhaka, Bangladesh from July 2012 to December 2012. All the type 2 diabetic patients admitted in the Department of Medicine in-patient department of ShSMCH who were 18 years and above age with both sexes were included as study population and were designated as group A and non-diabetic patients were included as group B. Blood samples were drawn after an overnight fast for the measurement of fasting blood sugar and serum magnesium. Result: In this present study a total number of 60 patients were enrolled for this study after fulfilling the inclusion and exclusion criteria of which 30 patients were in group A and the rest 30 patients were in group B. The correlation coefficient of FBS and HbA1C with Serum Magnesium level was recorded. The FBS and serum magnesium was negatively correlated to each other significantly which was -0.534. The HbA1C and serum magnesium was negatively correlated to each other significantly which was -0.556. Conclusion: In conclusion the blood sugar level is inversely correlate with the serum magnesium level in type 2 diabetic patients.

The objective of this study was to assess the association of in-hospital mortality risk based on change in serum magnesium levels in hospitalised patients. All adult patients admitted to our hospital from years 2009 to 2013 with at least two serum magnesium measurements during hospitalisation were included. Serum magnesium change, defined as the absolute difference between the highest and lowest serum magnesium, was categorised into six groups: 0–0.2, 0.3–0.4, 0.5–0.6, 0.7–0.8, 0.9–1.0, ≥1.1 mg/dL. In-hospital mortality was the outcome of interest. Logistic regression was used to assess the association between serum magnesium change and in-hospital mortality, using serum magnesium change of 0.0–0.2 mg/dL as the reference group. A total of 42 141 patients, with the median serum magnesium change during hospital stay of 0.3 (IQR 0.2–0.6) mg/dL, were studied. In-hospital mortality based on serum magnesium change of 0–0.2, 0.3–0.4, 0.5–0.6, 0.7–0.8, 0.9–1.0, ≥1.1 mg/dL was 1.3%, 2.3%, 3.1%, 5.0%, 6.5%, and 8.8%, respectively (p<0.001). After adjustment for potential confounders, increased serum magnesium change was significantly associated with higher in-hospital mortality with adjusted OR of 1.39 (95% 1.14–1.69) in serum magnesium change of 0.3–0.4, 1.48 (95% CI 1.21 to 1.81) in 0.5–0.6, 1.89 (95% CI 1.53 to 2.34) in 0.7–0.8, 1.85 (95% CI 1.45 to 2.37) in 0.9–1.0 and 1.89 (95% CI 1.48 to 2.41) in ≥1.1 mg/dL when compared with serum magnesium change group of 0–0.2 mg/dL. Increased in-hospital mortality was associated with both downward and upward trends of serum magnesium change during hospitalisation. The greater extent of change in serum magnesium levels was progressively associated with increased in-hospital mortality

Background/Aims: The study aimed at investigating the impact of serum magnesium (Mg) baseline level and its variability on mortality in maintenance hemodialysis (MHD) patients. Methods: Eligible patients receiving regular MHD at Ningbo No. 2 Hospital between January 2009 and August 2016 were enrolled and follow-ups were conducted afterwards until death or transplantation. General information, laboratory results, and outcomes of subjects were collected. The relationship between baseline serum Mg level, its coefficient of variation (CV), and all-cause mortality and cardiovascular disease mortality were assessed, respectively. Subjects were divided into groups in 2 manners: by serum Mg level (lower Mg group: serum Mg <1.00 mmol/L, higher Mg group: serum Mg ≥1.00 mmol/L) and by serum Mg CV (high variation group: CV ≥0.149 mmol/L, middle variation group: 0.114 mmol/L ≤ CV < 0.149 mmol/L, and low variation group: CV <0.114 mmol/L). Results: 169 MHD patients were recruited in the study, with mean serum Mg 1.00 ± 0.18 mmol/L, average age 60.20 ± 15.64 years, and median dialysis duration 37.00 (18.30, 77.97) months. During the follow-up, 69 (40.83%) patients died, 24 (34.78%) of which died due to cardiovascular disease. Comparing the two groups, patients in the lower Mg group had a higher all-cause mortality (50.00 vs. 29.33%, p = 0.007). The multivariate Cox regression analysis suggested that lower Mg level was an independent factor for all-cause mortality as well as cardiovascular mortality (HR = 13.268, 95% CI 6.234–28.237, p < 0.001; HR = 12.702, 95% CI 3.737–43.174, p < 0.001, respectively). However, there were no significant statistical differences of all-cause and cardiovascular mortality among these three groups concerning Mg variation. And in the univariate and multivariate Cox regression analysis, serum magnesium CV was not the independent factor for all-cause mortality and cardiovascular mortality. Conclusions: The lower baseline serum magnesium level was associated with all-cause and cardiovascular mortality in MHD patients. However, the variability of magnesium level was not independently associated with the risk of death and further studies need to be conducted.

Background: Serum magnesium level in pregnancy is a valuable tool to find out preterm onset of labour. In the asymptomatic group, greater surveillance and administration of steroids, tocolytics and transfer to a higher centre wherever necessary has to be done with mothers with low serum magnesium level. The objective of the study is to find association between serum magnesium levels and women with preterm labour, and to compare these values with those patients who have a term delivery.Methods: The subjects included 100 pregnant women with preterm labour (cases) between 28 and 37 weeks gestation (Group A) and similar number of pregnant women with term labour (controls) between 37 and 40 weeks (Group B). Inclusion criteria for cases was singleton pregnancy, painful uterine contractions more than two in 30 minutes, intact fetal membranes, cervical dilatation (at least 1 cm) and effacement (80%). Serum magnesium levels were done in both the groups. Patients were followed until delivery. Routine antenatal investigations were done. Serum levels of magnesium were estimated by Erba’s semi auto-analyser.Results: 62% patients in Group A were from rural areas. More patients in Group A (70%) were from low socioeconomic class. More women in Group A were anaemic (44%). Mean value of hemoglobin in Group A was 9.93gm/dL. More patients in Group A had muscle cramps (89%). VLBW (<1500gm) neonates were more in Group A (21%). Also, LBW (1500-2499gm) neonates were more in Group A (60%). Mean neonatal birth weight in Group A (1907.3gm) was less. Neonatal morbidity and mortality was observed significantly more in Group A. Mean serum magnesium was less in Group A. Mean serum magnesium levels in primi and multigravida patients were less in Group A. Moreover, mean serum magnesium levels were less in urban and rural patients in Group A. Mean serum magnesium levels were less in normal and overweight patients in Group A. Also, mean serum magnesium levels were less in patients with cervical dilatation <3cm and >3cm in Group A.Conclusions: Low maternal serum magnesium level is associated with preterm labour. Patients with preterm labour have significantly low serum magnesium level when compared with labour at term.

Background: The objective of present study was to measure the serum magnesium levels in preterm labor patients, to measure the serum magnesium levels in term labor patients and to correlate the serum magnesium levels in preterm and term labor patients.Methods: It is a prospective case control study conducted in the department of obstetrics and gynecology, KIMS hospital and research Centre, Bengaluru, Karnataka, India. A venous blood sample is drawn from patients admitted to labor room who fulfill the inclusion and exclusion criteria out of which 50 patients belong to the Group-A (preterm labor) and 50 patients belong to Group-B (term labor). Serum magnesium level is measured in both the groups.Results: Women with preterm labor had a significantly reduced serum magnesium level with a mean serum magnesium level of 1.59 mg/dl with a SD of 0.83 whereas the patients with term labor had a mean serum magnesium level of 2.55 mg/dl with a SD of 0.40. The difference of serum magnesium levels observed between the study population and control population is independent of factors like maternal age, parity, gestational age, and socio-economic factors. In this study, it is found that serum magnesium levels are lower in early and late preterm compared to preterm between 33-34+6 weeks.Conclusions: Serum magnesium level can be used as a predicting tool for preterm labor. Preterm labor can be avoided by simple supplementation of Magnesium which might provide an easy and inexpensive means to decrease the problems related to preterm labor. There is a further scope for research on serum magnesium levels based on gestational age.
