Vitamin D, known for its essential role in calcium and bone homeostasis, has multiple effects beyond the skeleton, including regulation of immunity and modulation of autoimmune processes. Several reports have shown suboptimal serum 25 hydroxyvitamin D [25(OH)D] levels in people with different inflammatory and autoimmune rheumatic conditions, and an association between 25(OH)D levels, disease activity and outcomes. Although most available data pertain to adults, insights often are extended to children.

Guidelines to provide an update of the previously published Polish recommendations for the management of women and men with osteoporosis have been developed in line with advances in medical knowledge, evidence-based data, and new concepts in diagnostic and therapeutic strategies. A Working Group of experts from the Multidisciplinary Osteoporosis Forum and from the National Institute of Geriatrics, Rheumatology, and Rehabilitation in Warsaw performed a thorough comprehensive review of current relevant publications in the field (including all age groups of people and management of secondary osteoporosis), and they evaluated epidemiological data on osteoporosis in Poland and the existing standards of care and costs. A voting panel of all co-authors assessed and discussed the quality of evidence to formulate 29 specific recommendations and voted independently the strength of each recommendation.

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. 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.

Article Synopsis
  • - The study examined the uncommon overlap of type 1 diabetes (T1D) and juvenile idiopathic arthritis (JIA) in children, focusing on how these autoimmune disorders are managed and treated together.
  • - Researchers reviewed existing literature on T1D and JIA in pediatric patients and analyzed two additional cases from a single center, finding a total of six patients, with varying treatments and outcomes.
  • - The coexistence of these conditions can complicate treatment, as hyperglycemia may exacerbate JIA symptoms; however, utilizing advanced diabetes technology can help improve metabolic control amidst ongoing arthritis therapy.

Juvenile idiopathic arthritis (JIA), as a chronic condition, is associated with symptoms negatively impacting health-related quality of life (HRQL). Regarding growing interest in the implementation of the patient-reported outcome measures (PROMs), we aimed to review the non-disease specific PROMs addressing HRQL assessment, potentially useful in the clinical care of JIA and daily practice. A systematic literature search was conducted using MEDLINE/PubMed, Google Scholar, Scopus and Embase databases (1990 to 2021), with a focus on the recent 5-years period.

Unlabelled: Low bone mineral density (BMD) was diagnosed in 24% of childhood cancer survivors (CCS), whereas very low BMD was relatively uncommon at 8%. We suggest that low BMD in CCS may become alleviated over time. Stem cell transplantation, radiotherapy, and underweight were the strongest independent predictors of decreased BMD.

Objectives Hypoparathyroidism is a rare disease in children that occurs as a result of autoimmune destruction of the parathyroid glands, a defect in parathyroid gland development or secondary to physical parathyroid gland disturbance. Typical symptoms of hypoparathyroidism present as hypocalcaemia and hyperphosphatemia due to decreased parathyroid hormone secretion and may lead to nerve and muscles disturbances resulting in clinical manifestation of tetany, arrhythmias and epilepsy. Currently, there is no conventional hormone replacement treatment for hypoparathyroidism and therapeutic approaches include normalising mineral levels using an oral calcium supplement and active forms of vitamin D.

Osteoarthritis (OA) is characterized by deterioration of the joints and associated with considerable pain and disability. OA is a chronic disease that requires intervention with both non-pharmacological and pharmacological treatment modalities and, inevitably, disease progression may necessitate successive treatments throughout the course of the disease. There is increasing data on the shortfalls of current pharmacological treatment of OA, and safety concerns associated with analgesic therapy use in OA arising from increasing evidence of gastrointestinal, cardiovascular, hepatic and renal adverse events with paracetamol and non-steroidal anti-inflammatory drugs (NSAIDs).

Objectives: The Sarcopenia Quality of Life (SarQoL) questionnaire, a sarcopenia-specific patient-reported outcome measure, evaluates quality of life with 55 items. It produces 7 domain scores and 1 overall quality of life score, all between 0 and 100 points. This study aims to contribute to the interpretation of the SarQoL scores by calculating the standard error of measurement (SEM) and smallest detectable change (SDC) in a sample of subjects from 9 studies.
