Catch it before it breaks!: managing metabolic bone disease of prematurity.

PURPOSE OF REVIEW

Metabolic bone disease of prematurity, commonly referred to as osteopenia of prematurity, remains prevalent in the neonatal intensive care unit (NICU) despite recent medical advances. It is estimated that up to 60% of extreme low birth weight and 20% of very low-birth-weight infants have metabolic bone disease of prematurity. Often silent, it typically presents with poor growth, increased ventilator dependency and fractures. Clinical sequalae, such as short stature can extend into young adulthood. There is no universal consensus by neonatal intensive care unit clinicians on the screening, diagnosis, or treatment for metabolic bone disease of prematurity. The disease is often diagnosed late by radiographs or incidentally in this highly fragile population.

RECENT FINDINGS

Suggest screening using DEXA (dual-energy X-ray absorptiometry) scans or ultrasound, in combination with serum markers like alkaline phosphatase, phosphorous levels, parathyroid hormone, and tubular reabsorption of phosphate, might identify at-risk babies earlier. The use of protocol-based screenings may aid in early diagnosis.

SUMMARY

We present a review of the risk factors, recent screening methods, diagnosis and management of this prevalent, clinically relevant diagnosis, as well as propose a protocol for the early screening and management of this silent disease.
