The oxidative metabolism of macrophages in vitamin E deficiency was studied on Aug-Lac strain rats. Vitamin E deficiency was shown to enhance luminol-dependent chemiluminescence of macrophages stimulated by opsonized zymosan. There was also an increase in microviscosity of macrophage membrane lipid phase, that was estimated with a fluorescent probe. The incubation of macrophages with dl-alpha-tocopherol led to the inhibition of macrophage chemiluminescence. Superoxide dismutase, glutathione peroxidase and glutathione reductase activity was not affected by vitamin E deficiency.

Tertiary hyperparathyroidism is characterized by hypercalcemia resulting from autonomous parathyroid hormone production and usually occurs after a prolonged period of secondary hyperparathyroidism. This condition can be a complication of X-linked hypophosphatemia (XLH), a rare genetic disease characterized by renal phosphate loss and consequent hypophosphatemia. Parathyroidectomy is considered the first-line therapy but surgical intervention can be complicated by hungry bone syndrome.

Ossification of the posterior longitudinal ligament of the vertebral column (OPLL) is a disease characterised by ectopic bone formation in the spinal ligament that causes progressive neurological impairment. However, there are no suitable treatments for OPLL. Here, we compared the general characteristics and haemostasis of patients with OPLL and those with cervical spondylotic myelopathy.

Kidney transplantation remains the gold standard treatment for end-stage kidney disease (ESKD), effectively alleviating numerous comorbidities and offering a substantial survival advantage over long-term dialysis. Despite advancements in immunosuppressive regimens and improvements in graft and patient survival rates, extended patient longevity brings an accumulating burden and complexity of bone disease in this population, which often goes underrecognized. The present study reviews the pathophysiology of CKD-MBD in pediatric KTR, focusing on the progression of bone disease before and after transplantation.
