New research reveals the clinical progression and evolution of pituitary hormone deficiencies in the first 3 years of life.

In a recent retrospective study published in Clinical Endocrinology, Jennifer M. Ladd, MD, MSc, pediatric physician in the Division of Endocrinology and associate program director of the Endocrinology Fellowship Program at Nationwide Children’s Hospital, and colleagues provide new insights into the clinical progression of congenital hypopituitarism in early childhood. This study represents one of the largest single-center cohorts examining the natural history of pituitary hormone deficiencies in children from birth to age 3 years.

“Pituitary hormone deficiencies are associated with significant morbidity, but we have limited understanding of the differences in how these deficiencies present and evolve during the neonatal and early childhood periods,” says Dr. Ladd. “Because there are highly effective treatments to replace missing hormones, the more we know, the earlier we can intervene before serious complications occur.”

The team analyzed clinical data from 56 patients born between 2009 and 2021. Each patient had at least one diagnosed pituitary hormone deficiency as well as abnormal pituitary or brain magnetic resonance imaging (MRI). Patients were classified into two groups: those with congenital isolated pituitary hormone deficiency (cIPHD, one deficiency) and those with congenital multiple pituitary hormone deficiencies (cMPHD, two or more deficiencies).

At the initial presentation, the cohort was about evenly divided; 46.4% had cIPHD, and 53.6% had cMPHD. There was no difference in gestational age, size at birth or sex. However, infants with cMPHD were diagnosed earlier than those with cIPHD.

“Children with multiple deficiencies were more likely to present symptomatically with hypoglycemia, as might be expected given many pituitary hormones are important for maintaining normal blood glucoses,” Dr. Ladd explains.

Infants found to have abnormal brain imaging without clinical signs were more likely to have cIPHD than cMPHD. The study showed no link between specific MRI abnormality and number of presenting pituitary hormone deficiencies.

“Brain imaging findings alone were not predictive of endocrine severity or progression. Although outside the scope of this study, we also know that some MRI abnormalities never result in pituitary hormone deficiencies. This is an important area for future research,” Dr. Ladd notes.

Critically, the study revealed that progression from cIPHD to cMPHD is common. By age 3 years, 65.4% of children initially diagnosed with cIPHD developed additional hormone deficiencies. Additionally, 78.9% of patients who started with two deficiencies progressed to three or four deficiencies by age 3 years.

“Our data show that the majority of patients will evolve to having more pituitary hormone deficiencies just within the first few years of life,” Dr. Ladd states.

These findings emphasize the need for ongoing, comprehensive endocrinology follow-up for all

children with congenital hypopituitarism, regardless of their initial presentation. Early detection and timely hormone replacement therapy are essential to prevent morbidity.

“Closely monitoring all patients over time and starting treatment early are all critical for protecting this high-risk population,” Dr. Ladd concludes.
