Frequency of Hypomagnesaemia in Children with Hypocalcemic Seizures

Aim: To determine the frequency of hypomagnesaemia in children with hypocalcemic seizures. Study Design: Cross sectional descriptive study. Place and Duration: Department of Pediatrics, Liaquat University Hospital, Jamshoro / Hyderabad. From November 2017 to April 2018. Methodology: Children (06 months to 06 years age and of either gender) having Two or more than two hypocalcemic seizures within 12 hours duration were included in the study . The children with hypocalcemic seizure were assessed for magnesium deficiency (hypomagnesaemia). The evaluation of hypomagnesaemia was done according to the cut off / reference values for hypomagnesaemia (<1.8 mg/dl). The data was collected on pre-structured proforma (attached). Results: Total 147 children with hypocalcemic seizures were taken in this study, among them 49 (33.3%) patients had found low magnesium level and 98 (54.4%) patients had normal magnesium level. Conclusion: Seizures associated with hypocalcaemia is one of the common type of convulsion in children. In our study, a positive relation was found between low levels of serum magnesium and hypocalcemic seizures.

Morphofunctional characterization of rat thymus mast cells after administration of magnesium orotate mechanically activated forms

Relevance. The topicality of the work is determined by the wide spread of hypomagnesemia among the people, which makes it necessary to correct it. The aim of the work is to elucidate the cell-mediated response of the thymus mastocytic link to magnesium deficiency and its correction by the mechanoactivated form of magnesium orotate. Materials and Methods . Animals with drug-induced magnesium deficiency (administration of furosemide 30 mg/kg for 14 days) were administered either the initial preparation Magnerot (Magnerot, Vervag Pharma, Germany), or its mechanoactivated form. The level of magnesium in the blood was determined by test systems ARKREY (Japan). The concentration of magnesium in the thymus tissue was determined by the method of emission spectroscopy with inductively coupled (argon) plasma on an atomic emission spectrometer. Density of mastocytes and the indices of degranulation and granulolosis were calculated on paraffin sections of the thymus after coloration with toluidine blue. Results and Discussion . It was shown that furosemide administration the amount of magnesium decreased in the blood (from 1,750,08 to 0,9020,18 mmol/l, p0,05), but increased in the thymus (from 1,60,6 in the control to 3,71,2 mg/l); in the gland tissue, the number of mastocytes of morphotype A decreased and the number of mastocytes of morphotype D, after active degranulation, increased (by 7,1 times, p0,05). The type of mastocyte secretion in hypomagnesemia is represented by the merocrine variant. The administration of the initial magnesium orotate led to an increase in the concentration of magnesium in the blood to 1,150,25 mmol/l, which is 65,7% of the initial level, the amount of magnesium in the thymus remained elevated (3,41,1 mg/l), the number of actively degranulating cells (morphotype D) was increased. Mechanoactivated magnesium orotate restored the concentration of Mg2+ in the blood to 89,1% (1,560,18 mmol/l, p0,05) and decreased in the thymus (to 2,30,7 mg/l), restored the subpopulation of mastocytes saturated with heparin (type A), reduced the number of mastocytes of morphotype D. Conclusion . The mechanoactivated form of magnesium orotate has a normalizing effect on the population of thymic mastocytes, shows pronounced immunomodulatory activity, which allows us to consider it as a potential therapeutic agent for clinical testing in the complex therapy of hypomagnesemia and associated immunodeficiency.

Physiology of magnesium metabolism and the use of magnesium in intensive care (literature review with the results of personal observations, part 3)

In this review, we presented the results of experimental and clinical studies that most convincingly demonstrate the role of magnesium metabolism disorders in the development of myocardial damage, fatal arrhythmias, and arterial hypertension. We also highlighted the diagnosis of latent magnesium deficiency in the body and the role of magnesium deficiency in the pathogenesis of cardiomyopathy, congestive heart failure, and mitral valve prolapse. Oral Mg supplementation helps to reduce mean arterial pressure, peripheral vascular resistance, and the frequency of isolated and burst ventricular extrasystoles and attacks of unstable ventricular tachyarrhythmia. The researchers found that many patients with severe mitral valve prolapse had low serum Mg levels, and Mg supplementation was associated with improved patient outcomes. Monitoring the status of magnesium metabolism in the body is ne-cessary not only in intensive care and in the hospital as a whole but is also relevant in outpatient practice. The cost of magnesia therapy is quite low, but at the same time, regular intake of magnesium preparations or dietary supplements, containing mainly magnesium, can significantly improve the results of treatment of many diseases and prevent the development of complications that are dangerous for the body.

Association between magnesium concentrations and prediabetes: a systematic review and meta-analysis

Studies on the association between serum magnesium level and prediabetes yielded inconsistent results. Therefore, the present meta-analysis was designed to examine the association between serum magnesium levels and prediabetes. Online databases including PubMed, Embase, Scopus and Google Scholar were searched up to October, 2020. A total of 10 studies that reported mean and standard deviation (SD) of magnesium levels in prediabetes and healthy control group were identified. Random effects models were used to pool weighted mean differences (WMDs) of serum magnesium levels. Pooled-analysis showed that subjects with prediabetes had significantly lower serum magnesium levels compared with healthy controls (WMD = − 0.07 mmol/L; 95% CI − 0.09, − 0.05 mmol/L, P < 0.001). A significant heterogeneity observed across included studies (I2 = 95.6%, P < 0.001). However, different subgroup analysis did not detect the potential source of observed heterogeneity. Withdrawal of each individual study had no effect on the overall results. The present meta-analysis showed that circulating magnesium levels in people with prediabetes were significantly lower than healthy controls, confirming that magnesium deficiency may play a role in development and progression of prediabetes. Further studies with larger sample size and robust design are warranted to confirm present results.

Micronutrient deficiency in menstrual dysfunction among women of reproductive age

Objective. To determine whether inorganic menstrual dysfunction (MD) is associated with magnesium, iron and vitamin D deficiency in women of reproductive age. Materials and methods. The study group I consisted of 50 women with MD: dysmenorrhea (16 women), oligomenorrhea (12 women), functional hypothalamic amenorrhea (3 patients) and acyclic abnormal uterine bleeding (19 women), the comparison group II was composed of 30 patients with normal menstrual function. The methods of study included history taking using a questionnaire to detect the signs of magnesium deficiency, physical examination, echography of pelvic organs, full blood count, blood tests to determine the concentration of magnesium, vitamin D and ferritin as well as consulting a therapeutist. Results. Magnesium deficiency was registered significantly more often in patients with MD (93.0 3.6 %, 73.0 8.1 %, respectively; p 0.05). The most typical signs of magnesium deficiency were the central symptoms: headache (58.0 7.1 %, 22.0 7.6 %; p 0.001), irritability (53.0 7.1 %, 26.0 8.0 %; p 0.01), dyssomnia (45.0 7.0 %, 17.0 6.9 %; p 0.01), dizziness (42.5 7.0 %, 22.0 7.6 %; p 0.05), a decrease in libido (34.0 6.7 %, 13.0 6.1 %; p 0.05), as well as trophic disturbances including hair loss (38.0 6.9 %, 13.0 6.9 %; p 0.01). Similar findings were obtained when we studied the iron supply: the frequency of latent iron deficiency (according to ferritin concentration) was 77.0 5.9 and 35.7 8.4 % respectively; p 0.001. Deficiency or insufficient supply of 25(ОH)D was registered significantly more often in women with MD in comparison with healthy women (45.0 7.0 %, 20.0 7.3 %; p 0.05). Conclusions. In summary, determination of the level of micronutrients and adequate compensation of their deficiency can be important factors in physiological correction of endocrine imbalance leading to functional disorders in the reproductive system and a decrease in fertility.
