Insights

Children with familial Mediterranean fever (FMF) have lower vitamin D levels than healthy children. This suggests vitamin D deficiency screening and supplementation may be beneficial for FMF patients.

Area of Science:

  • Pediatrics
  • Immunology
  • Endocrinology

Background:

  • Familial Mediterranean fever (FMF) is a genetic autoinflammatory disease.
  • Vitamin D plays a crucial role in immune function and bone health.
  • The relationship between FMF and vitamin D status is not well-established.

Purpose of the Study:

  • To investigate the prevalence of vitamin D deficiency in children diagnosed with FMF.
  • To compare vitamin D levels in pediatric FMF patients with healthy controls.

Main Methods:

  • A case-control study involving 100 children with FMF and 50 healthy children.
  • Measurement of serum 25-hydroxyvitamin D levels.
  • Analysis of demographic and clinical parameters, including MEFV mutations and parathyroid hormone levels.

Main Results:

  • Children with FMF exhibited significantly lower serum vitamin D levels compared to healthy controls (24.78 vs. 28.70 ng/mL, P=0.039).
  • Vitamin D levels did not differ significantly across various MEFV mutations (P=0.633).
  • A significant negative correlation was observed between vitamin D levels and parathyroid hormone (rs=-0.382, P<0.0001), and age (r=-0.235, P=0.019).

Conclusions:

  • Pediatric patients with FMF demonstrate lower vitamin D levels than their healthy peers.
  • Routine assessment of vitamin D status and potential supplementation are recommended for children with FMF.
  • Further large-scale studies are warranted to confirm the incidence of vitamin D deficiency in FMF.

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Connective Tissue Cell Types

Connective tissue develops from the mesoderm of a developing embryo and consists of cells, fibers, and ground substance: a gel-like material containing large complexes of carbohydrates and proteins. Connective tissue was first identified as a separate tissue family in the 18th century, and Johannes Peter Muller coined the term connective tissue.
Fat cells (adipocytes), smooth muscle cells (myoblasts), and bone cells (osteoblasts) are some connective tissue cell types. Some immune system cells...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Myasthenia Gravis: Diagnostic Tests

Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...
