Propranolol benefits infantile tremor syndrome after initiating vitamin B12 therapy: Case Study

Propranolol is beneficial for the treatment of infantile tremor syndrome (ITS) in the context of vitamin B12 deficiency, according to a recent case study published in the Frontiers in Pediatrics.

Children with vitamin B12 deficiency can present with anaemia, pancytopenia, failure to thrive, hypotonia and developmental delays and/or regression. Vitamin B12 deficiency can be seen in infants who are exclusively breastfed by mothers who are vegetarian or who are themselves vitamin B12 deficient. Investigations in children with vitamin B12 deficiency can reveal macrocytic anaemia, leukopenia, thrombocytopenia, high serum homocysteine levels and high lactate dehydrogenase (LDH) levels. Peripheral blood smears may show macrocytic hypochromic oval erythrocytes, anisocytosis, poikilocytosis, and hyper-segmentation of neutrophils. Furthermore, head imaging may reveal cerebral atrophy and delayed myelination patterns for age. Early recognition and treatment of vitamin B12 deficiency can lead to significant improvement in terms of neurodevelopment and prevent long term neurological consequence

A previously healthy 13-month-old girl was referred to a tertiary pediatric care centre for further investigations and management of her pancytopenia. She was initially seen by a general paediatrician in the community for concerns of a 2-month history of tiredness, decreased appetite and failure to thrive. Further investigations revealed that her anaemia was macrocytic: her MCV was 107.4 fL (range 79–97 fL). She was diagnosed with infantile tremor syndrome (ITS), which was likely triggered by her vitamin B12 treatment, as described in the literature. She also had undetectable vitamin B12 levels (<100 pg/mL, normal range 160–950 pg/mL), as well as high lactate dehydrogenase (LDH) levels (>4,300 U/L, normal range 373–618 U/L). Her reticulocyte count was also inappropriately within the normal range (61 × 103/μL, normal range 19–73 × 103/μL) given her significant anaemia. Her other nutrients including iron and folic acid were within normal range. Immunoglobulin levels were not measured.

She was closely followed by general paediatrics, haematology and neurology as an outpatient. She continued to show dramatic improvements in terms of neurodevelopment: within a month, she was sitting unsupported, was able to stand with minimal support and started to crawl. Her oral intake also increased significantly, and she was transitioned off of nasogastric tubes 4 months after her admission. Given the significant improvement in her tremors, she was weaned off of the propranolol after 6 weeks of treatment without any rebound in her symptoms.

Thus, this case highlights the efficacy and safety of propranolol for the treatment of ITS in the context of vitamin B12 deficiency. From a parental perspective, addressing these tremors provided reassurance and allowed their daughter to progress in terms of developmental skills. However, it is a limited report with only one case. Further studies are needed to identify the optimal treatment protocol for tremors associated with infantile tremor syndrome and vitamin B12 deficiency.
