Different Regimens of Vitamin D in treatment of children with chronic liver disease

Abstract Background Vitamin D is a steroid based hormone that has crucial role in calcium metabolism and bone homeostasis and potential role in fibrosis including liver. Patients with chronic liver disease has tendency for vitamin D deficiency with possible sequalae including hepatic osteodystrophy. Safe and effective regime of vitamin D that can be used in children with chronic liver disease is still not well established. Moreover, the potentiality of reversing fibrosis process or halting it by correction of vitamin D is still not well studied. Aim of work The primary aim of the study is to assess the efficacy and safety of vitamin D regime using two different mode of administration. The secondary aim is to assess the possible antifibrotic effect of vitamin D therapy by assessment of fibroscan. Methodology Twenty four children with different etiologies of chronic liver disease but age and sex matched as well as anthropometric measures are enrolled in the study. They were distributed randomly among the two arms of the study and followed up for 6 months using different laboratory and imaging variables. The two regimes were group A who received intramuscular stoss dose once (200.000 IU) vitamin D therapy while group B received oral vitamin D therapy with dose 50.000 IU for four weeks. All children received maintenance vitamin D (600 IU) and Ca doses thereafter for the whole follow up period. All patients were subjected to complete history taking, complete clinical examination including abdominal examination, signs of liver decompensation and signs of vitamin D deficiency. As regard laboratory investigations done were CBC, liver function tests, serum calcium and phosphorous. Serum vitamin D level and fibroscan were also done at the beginning and the end. Results There were significant improvement of vitamin D level in both arms with no development of toxic s/o of vitamin D toxicity with p-value of < 0.001 and 0.000 respectively in group A and B. The difference of improvements between both arms were not significant display the equal efficacy of both regimes (P = 0.885). There were no significant improvement of fibroscan parameters following vitamin D treatment in either group A or B with p-value 0.637 and 0.931 respectively. Conclusion Stoss and oral vitamin D regimes suggested in the study are both equally effective and safe in the treatment of vitamin D deficiency among children with chronic liver disease. Despite no proof of antifibrotic effect upon vitamin D correction, further study is required to evaluate this issue.
