Official title: The Role of Vitamin K2 in Preventing Glucocorticoid-Induced Bone Loss in Children With Nephrotic Syndrome

Run by Ain Shams University · NCT07206537 · Data updated 2026-11-12

Is this trial a fit for you?

Likely a good fit

Children under 16 with nephrotic syndrome who have been on glucocorticoid therapy for more than six months, have sufficient vitamin D levels, and do not have impaired kidney function or excluded comorbidities are ideal candidates.

Probably not a fit

Children with impaired kidney function, malabsorption of fat-soluble vitamins, prior fractures, genetic nephrotic syndromes, or known vitamin K disorders are unlikely to benefit or be eligible.

What this trial studies

This interventional study gives oral vitamin K2 supplements to pediatric patients with nephrotic syndrome who have received glucocorticoids for more than six months and monitors changes in bone metabolism. Participants undergo baseline and follow-up measurements of bone health markers and clinical monitoring while continuing standard nephrotic syndrome care. The protocol excludes children with impaired kidney function, malabsorption disorders, prior fractures, genetic forms of nephrotic syndrome, or vitamin K–related disorders to isolate the effect of supplementation. The goal is to determine whether vitamin K2 improves biochemical and clinical indicators of bone strength in this vulnerable population.

Why it matters

Potential benefit: If effective, vitamin K2 supplementation could reduce steroid-related bone loss and lower future fracture risk in affected children.

How similar studies have gone: Some adult and biochemical studies suggest vitamin K2 can improve bone metabolism, but evidence specifically in children with steroid-induced bone loss is limited.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Nephrotic patients under 16 years of age of both genders who were treated with GC for the first time. GC treatment was initiated at a dose of 2 mg/kg/day prednisolone with gradual dose reduction.
* All patients have been on glucocorticoid therapy for more than 6 months. All patients have sufficient vitamin D level 30 ng/ml (75 nmol/L) or above.

Exclusion Criteria:

1. Patients with impaired kidney functions.
2. Non-compliant patients on medications or vitamin supplements.
3. Diseases that affect fat-soluable vitamins absorption such as gallbladder or biliary disease, cystic fibrosis, celiac disease, etc.
4. History of vitamin K-related disorders as bleeding disorders, osteomalacia , etc.
5. History of bone fracture before the study.
6. Any nephrotic syndrome with identified genetic causes.
