Insights
Children with recurrent bronchitis show altered bone metabolism and decreased bone mineral density (BMD). This study highlights vitamin D deficiency and increased bone resorption in these children.
Area of Science:
- Pediatrics
- Bone Metabolism
- Respiratory Health
Background:
- Recurrent bronchitis (RB) is a common childhood illness.
- Bone health is crucial for overall child development.
- The relationship between RB and bone metabolism requires further investigation.
Purpose of the Study:
- To assess bone metabolism and bone mineral density (BMD) in children diagnosed with recurrent bronchitis.
- To compare bone health markers between children with RB and healthy controls.
Main Methods:
- Examined 120 children aged 6-10 years, divided into two groups: 60 with RB and 60 controls.
- Measured serum levels of alkaline phosphatase, osteocalcin, collagen type 1 degradation products, parathyroid hormone, and 25(OH)D.
- Utilized Dual-energy X-ray Absorptiometry (DXA) to assess bone mineral density (BMD) at various skeletal sites.
Main Results:
- Children with RB exhibited significantly higher alkaline phosphatase, osteocalcin, collagen type 1 degradation products, and parathyroid hormone levels compared to controls.
- A higher prevalence of vitamin D deficiency (serum 25(OH)D < 30 ng/ml) was observed in children with RB (59.3% increase).
- DXA scans revealed decreased BMD in a significant percentage of children with RB across lumbar vertebrae and femur neck regions.
Conclusions:
- Children with recurrent bronchitis demonstrate an activated bone resorption process.
- Vitamin D deficiency is prevalent in children with RB and is associated with decreased bone mineral density.
- Findings suggest a link between recurrent bronchitis and compromised bone health in children.
Abstract:
The aim - to determine the bone metabolism status and bone mineral density (BMD) in children with recurrent bronchitis (RB). 120 children aged 6 to 10 years were examined. Formed 2 groups: 1st group - children with RB (n=60); 2nd group - children occasionally suffering of upper respiratory tract infections (n=60). The average age was 8 years 2 months. Among children with RB, compared with children of the 2nd group, an increase in the number of patients with an increase in alkaline phosphatase activity (by 35.0%) (p<0.05), and serum osteocalcin level (by 66.7%) (p<0.05) was revealed, collagen type 1 degradation products (by 15.0%) (p<0.05), parathyroid hormone (by 13.3%) (p<0.05), decrease of serum 25(OH)D less than 30 ng/ml (by 59.3%) (p<0.05). A DXA in children with RB showed the presence of 24 (40.0%) episodes of decreased BMD in the L1, 25 (41.7%) episodes in L2, 24 (40.0%) episodes in L3, 27 (45.0%) episodes in L4, 28 (46.7%) cases in the left femur neck, 22 (36.7%) cases in the right femur neck. In children with RB was established activation of bone resorption on background of vitamin D deficiency and BMD decrease.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Hormones and Bone Tissue
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
Essential Minerals for Bone Health
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
