Guidelines for Preventing and Treating Vitamin D Deficiency: A 2023 Update in Poland.

Introduction: All epidemiological studies suggest that vitamin D deficiency is prevalent among the Polish general population. Since vitamin D deficiency was shown to be among the risk factors for many diseases and for all-cause mortality, concern about this problem led us to update the previous Polish recommendations. Methods: After reviewing the epidemiological evidence, case-control studies and randomized control trials (RCTs), a Polish multidisciplinary group formulated questions on the recommendations for prophylaxis and treatment of vitamin D deficiency both for the general population and for the risk groups of patients. The scientific evidence of pleiotropic effects of vitamin D as well as the results of panelists' voting were reviewed and discussed. Thirty-four authors representing different areas of expertise prepared position statements. The consensus group, representing eight Polish/international medical societies and eight national specialist consultants, prepared the final Polish recommendations. Results: Based on networking discussions, the ranges of total serum 25-hydroxyvitamin D concentration indicating vitamin D deficiency [<20 ng/mL (<50 nmol/L)], suboptimal status [20-30 ng/mL (50-75 nmol/L)], and optimal concentration [30-50 ng/mL (75-125 nmol/L)] were confirmed. Practical guidelines for cholecalciferol (vitamin D3) as the first choice for prophylaxis and treatment of vitamin D deficiency were developed. Calcifediol dosing as the second choice for preventing and treating vitamin D deficiency was introduced. Conclusions: Improving the vitamin D status of the general population and treatment of risk groups of patients must be again announced as healthcare policy to reduce a risk of spectrum of diseases. This paper offers consensus statements on prophylaxis and treatment strategies for vitamin D deficiency in Poland.

Do trace elements influence the course of newly diagnosed type 1 diabetes mellitus?

OBJECTIVE: The etiology of type 1 diabetes mellitus (DM1) is not fully understood. Some studies indicate an excess or deficiency of certain trace elements may affect glucose and insulin metabolism. This study aimed to assess the concentrations of trace elements in children with newly diagnosed DM1. The study group comprised 35 children aged 3-17 years (mean, 8.83±3.55 years). Serum concentrations of selenium, zinc, copper, and arsenic were determined at the time of diagnosis, after ~2 weeks (during insulin treatment), and after 6 months. No trace element deficiency was observed. Selenium levels were increased at all time points (77.61±14.03 µg/l; 70.42±11.04 µg/l; 75.79±12.89 µg/l). Arsenic levels were increased at the time of discharge (0.30±0.24 µg/l) and upon 6 months control visit (0.67±1.98 µg/l) for DM1. Copper levels were elevated at the time of diagnosis (1333±244 µg/l). No significant differences were observed in zinc concentrations between study and control group or between time points. Trace elements in the environment, especially selenium, may increase the incidence of DM1, although further research is required to confirm this association.

Management of Prader-Willi Syndrome (PWS) in adults - what an endocrinologist needs to know. Recommendations of the Polish Society of Endocrinology and the Polish Society of Paediatric Endocrinology and Diabetology.

Prader-Willi syndrome (PWS) is a complex genetic disorder characterised by a set of phenotypic traits, which include infantile hypotonia, short stature, and morbid obesity. Over the last 12 years, visible progress has been made in medical care management of PWS patients in Poland. Increasing awareness of the disorder in neonatal and paediatric care has led to early identification of the condition in neonates, followed by the institution of an appropriate dietary regime, introduction of physiotherapy, and early-onset recombinant human growth hormone (rhGH) treatment. Growth hormone (GH) therapy in Poland is conducted within the nationwide framework of the Therapeutic Programme: "Treatment of Prader-Willi Syndrome". The therapeutic interventions initiated in the paediatric centres need to be continued in multidisciplinary adult care settings. The main aim of PWS clinical management in adulthood is prevention of obesity and its comor-bidities, treatment of hormonal disorders, mental health stabilisation, nutritional guidance, as well as on-going physiotherapy. Integrated multidisciplinary therapeutic intervention is necessary if patients with such a complex genetic condition as PWS are to not only achieve an average life expectancy but also to enjoy higher quality of life.

Vitamin D Supplementation Guidelines for General Population and Groups at Risk of Vitamin D Deficiency in Poland-Recommendations of the Polish Society of Pediatric Endocrinology and Diabetes and the Expert Panel With Participation of National Specialist Consultants and Representatives of Scientific Societies-2018 Update.

INTRODUCTION: Vitamin D deficiency is an important public health problem worldwide. Vitamin D deficiency confers a significant risk for both skeletal and non-skeletal disorders and a number of lifelong negative health outcomes. The objectives of this evidence-based guidelines document are to provide health care professionals in Poland, an updated recommendation for the prevention, diagnosis and treatment of vitamin D deficiency. METHODS: A systematic literature search examining the prevention and treatment strategies for vitamin D deficiency was conducted. Updated recommendations were developed using the Grading of Recommendations, Assessment, Development and Evaluation system describing the strength of the recommendation and the quality of supporting evidence. Twenty-seven contributors representing different areas of expertise and medical specialties, including pediatricians, geriatricians, endocrinologists, epidemiologists, nephrologists, gynecologists and obstetricians evaluated the available published evidence related to vitamin D, formulated the goals of this document and developed a common consolidated position. The consensus group, representing six national specialist consultants and eight Polish and international scientific organizations/societies, participated in the process of grading evidence and drawing up the general and specific recommendations. RESULTS: The updated recommendations define the diagnostic criteria for the evaluation of vitamin D status and describe the prevention and treatment strategies of vitamin D deficiency in the general population and in groups at increased risk of the deficiency. Age- and weight-specific recommendations for prevention, supplementation and treatment of vitamin D deficiency are presented, and detailed practice guidance is discussed regarding the management in primary and specialized health care. CONCLUSION: Vitamin D deficiency remains still highly prevalent in Poland, in all age groups. Currently, there is a great necessity to implement a regular supplementation with recommended doses and to develop an effective strategy to alleviate vitamin D deficiency in the population. These updated recommendations are addressed to health professionals and the authorities pursuing comprehensive health policies and should also be included in public health programs aimed at preventing a broad spectrum of chronic diseases.
