Hear from Dr Andrew Dauber and Dr Marta Ramón Krauel in this podcast as they explore short stature conditions, including SPIGFD (severe primary IGF-1 deficiency) / growth hormone resistance, through real patient cases and clinical insights. While growth hormone deficiency is a well-known cause of short stature, this discussion covers patient cases where growth hormone levels are normal or even elevated, yet IGF-1 levels remain low—a hallmark of primary IGF-1 deficiency.

Gain valuable knowledge on identifying and managing this rare condition, with practical takeaways for clinical practice.

Key clinical takeaways:

• Growth hormone resistance can range from severe IGF-1 deficiency, like in classic Laron syndrome, to milder mutations in the same receptor. There can also be mutations in other parts of the signalling pathway

• Patients with SPIGFD have low IGF-1 levels resulting from growth hormone resistance or insensitivity, rather than deficiency, as they produce sufficient or even high levels of growth hormone without secondary causes of growth failure

• Laron syndrome, a classic form of SPIGFD, is characterised by severe short stature and distinct features such as spontaneous hypoglycemia, mid-face hypoplasia, frontal bossing, a high-pitched voice, and underdeveloped genitalia in boys

• Early and accurate diagnosis of SPIGFD is crucial for effective management, as growth hormone therapy is ineffective for these patients; recognising the distinction between severe and less severe IGF-1 deficiency, as well as primary versus secondary causes, ensures appropriate treatment to ensure optimal outcomes

• Recombinant IGF-1 therapy is indicated for patients with SPIGFD. Healthcare professionals must monitor for adverse events such as hypoglycemia and potential malignancies
