(Family Features) Pediatric growth hormone deficiency (GHD) is a relatively rare condition, affecting an estimated 1 in 4,000-10,000 children. Despite its rarity, GHD can significantly impact a child’s growth and development, which can potentially lead to short stature, delayed puberty, decreased muscle mass, delay in bone maturation and psychosocial implications.

With early diagnosis and appropriate treatment, children with GHD can achieve improved growth outcomes and lead healthy lives. Increasing understanding of GHD treatment options and closing knowledge gaps can make a difference in the patient and caregiver journey.

What is PGHD?
Growth hormone plays a critical role in helping young bodies grow and develop, including improving muscle metabolism, growing bones and breaking down fats.

PGHD occurs when a child’s pituitary gland is unable to produce enough growth hormone which results in noticeable changes on the growth chart.

Children with PGHD may look younger than their peers of the same age and gender, and puberty may be delayed or absent. Muscle development, metabolism and bone strength may also be impacted by insufficient or inadequate levels of growth hormone.

While growth hormone stimulates height increase during development, its role in the body extends beyond childhood. Even after growth plates close, growth hormone plays a vital role for cardiovascular health and for maintaining normal body structure and metabolism. Research also indicates osteoporosis as a long-term implication of GHD, highlighting its importance in overall health and well-being.

What are the Symptoms?
PGHD may be apparent during infancy, or it may not be revealed until later in childhood. Children with PGHD tend to have typical body proportions but noticeably slow growth. Other symptoms may include an immature or significantly younger look than other children of the same age, chubby body build, slow hair and nail growth, teeth that come in late and episodes of low blood sugar.

Children who have experienced a brain injury, brain tumor or radiation treatment involving the head are at higher risk for PGHD. Genetic factors can also increase risk.

How are Children Diagnosed?
Generally, doctors attempt to rule out other causes of slow growth, which may include genetic short stature, poor nutrition – which may be the result of an underlying condition such as celiac disease – and other genetic conditions, such as a hypothyroidism or Turner syndrome.

X-rays to evaluate bone age and imaging to identify the location of the pituitary gland can support the diagnosis. Another common screening option is a growth hormone stimulation test, in which medications are administered to trigger the release of growth hormone and blood is drawn frequently to monitor the body’s response.

What Treatment Options are Available?
Once a diagnosis is confirmed, children with PGHD often work closely with an endocrinologist to develop a treatment plan that includes growth hormone replacement therapy and closely monitor future growth. Dosing is based on weight and requires ongoing monitoring for adjustments. Traditionally, treatment was through daily injections, but more recently, weekly injections became available.

Children with PGHD who begin treatment early in life are more likely to reach adult height consistent with their family’s stature.
