A Study of Vitamin B12 Status in Children With Infantile Tremor Syndrome and Pre Infantile Tremor Syndrome
PRIMARY OBJECTIVES
• To describe the vitamin B12 status in children with infantile tremor syndrome(ITS) and Pre ITS
SECONDARY OBJECTIVES
- To study the vitamin B12 status in mothers of children with infantile tremor syndrome (ITS) and Pre ITS
- To study the blood levels of folate in children with infantile tremor syndrome (includes Pre ITS) and their mothers.

PLAN OF THE STUDY All consecutive patients who present in Pediatric Emergency and OPD in Advanced pediatric Centre with suspected Infantile tremor syndrome will be screened for inclusion in the study. Those found eligible would be included after an informed consent. Baseline clinical and demographic profile will be recorded on a proforma..The study aims at assessment of vitamin B12 status in children with ITS. The various manifestations of the syndrome, the presentations, the clinical picture, the development profile, various haematological and biochemical markers would be studied in a detailed manner and recorded on a proforma (annexure).
The first section of the proforma is targeted at the clinical picture of the disease. The presenting features will be recorded. The presenting complaints which can be anything ranging from an episode of upper respiratory tract infection to an apparently healthy child presenting with delayed milestones. A brief history of the development milestones achieved under gross motor, fine motor, language and social milestones is important and form a basis for screening the developmentally delayed children .A feeding history will be taken and is important as this disease is more frequently seen in children who are exclusively/predominantly breastfed. A detailed examination of the child would be done and the findings recorded. Skin and hair changes are very classical of this disease and hence will be to be studied and recorded in detail. A neurological examination will be done to study the neurological status of the children and presence of any extrapyramidal symptoms. Hematological indices will be recorded. Plasma Vitamin B 12, folate, homocysteine levels will be studied.Urine methylmalonic acid along with TMS/GCMS will also be done as a part of this project. Other investigations will be done as per case profile. Any other investigation if done for the case as a part of the treatment or diagnostic evaluation like liver function tests, renal function tests , EEG, CT, MRI will also be recorded.
The second section of the proforma consists of assessment of health and nutritional status of the mother. It aims at establishing any direct relation between the maternal health and development of ITS like picture in their children. Mother's dietary history will be taken to find out whether the maternal diet is lacking in Vitamin B12 and folate. A targeted neurological examination will be done to look for neurological manifestations of vitamin B12 deficiency in form of posterior column tract sensation and presence of peripheral neuropathy. A lab estimation of maternal Vitamin B12,folate and homocysteine levels will also be done and recorded.
Blood samples: Sampling would be done along with routine sampling as far as possible to avoid additional pricks to the child. Plasma would be immediately separated and stored and tested for Vitamin B12 ,homocysteine, methylmalonic acid and folate levels. This blood would be taken from sample already taken for other tests to be done in the child. Confidentiality of records would be maintained. The study is purely observational and will not influence the management of the child. Though as a standard policy all children with ITS would receive Vitamin B12, folate and other supplements and diet counseling will be done.
Blood TMS-acylcarnitine and propionylcarnitine along with evaluation of urine methyl malonic acid as a part of GCMS will also be studied in cases and controls.
Mother's blood samples will also be taken after explaining to them the entire aims and objectives of the study and taking full free voluntary informed consent from them. This would also benefit the mothers in a way because those identified with a deficiency will be given supplements to overcome the deficiency.
Control samples will be taken from children of the same age group admitted for some other ailment. A 2 ml sample will be taken from sample already drawn for other tests to be done in the child. The controls also stand to be benefitted because all children found deficient will be advised Vitamin B12 and folate supplementation immediately.
Vitamin B12 and folate levels will also be studied in the mothers of the 50 controls. All mothers found deficient will be advised Vitamin B12 and folate.
