Leschke syndrome
A rare disorder with adrenal insufficiency, short stature, and intellectual disability.
Overview
Leschke syndrome is a rare and poorly understood congenital disorder that primarily affects growth and endocrine function. It is characterized by a combination of short stature, delayed puberty, and sometimes intellectual disability. Leschke syndrome is considered a type of pituitary hormone deficiency, particularly involving growth hormone and gonadotropins. The condition is extremely rare, and most information about it comes from isolated case reports and small series in medical literature.
Causes
The exact cause of Leschke syndrome remains unclear. It is believed to involve dysfunction of the hypothalamic-pituitary axis, leading to deficiencies in growth hormone and other pituitary hormones responsible for sexual development. Some researchers suggest that it may have a genetic basis, but no specific causative gene has been conclusively identified. In most cases, the condition appears sporadically without a clear pattern of inheritance.
Symptoms
The clinical features of Leschke syndrome typically present in childhood or adolescence and include:
Short stature – significantly below average height for age and sex, due to growth hormone deficiency
Delayed or absent puberty – due to gonadotropin deficiency, resulting in underdeveloped secondary sexual characteristics
Hypogonadism – small testes in males or underdeveloped breasts and amenorrhea in females
Intellectual disability – reported in some cases, though not universally present
Possible facial dysmorphism – such as a high forehead or prominent eyes in rare reports
Diagnosis
Diagnosis of Leschke syndrome involves clinical evaluation, hormonal testing, and exclusion of other causes of short stature and delayed puberty. The diagnostic workup may include:
Physical examination – assessment of growth parameters and secondary sexual characteristics
Growth hormone stimulation tests – to confirm growth hormone deficiency
Gonadotropin and sex hormone levels – to evaluate pituitary function and puberty status
Brain MRI – to check for structural abnormalities of the pituitary gland or hypothalamus
Bone age assessment – typically delayed relative to chronological age
Treatment
Treatment for Leschke syndrome focuses on hormone replacement therapy to address growth and pubertal delays. Common approaches include:
Recombinant human growth hormone (rhGH) – to promote height gain in children with confirmed deficiency
Sex hormone replacement therapy – testosterone for males and estrogen/progesterone for females to initiate and maintain puberty
Educational support – for individuals with cognitive or learning difficulties
Regular monitoring – by an endocrinologist to adjust hormone therapy and track growth and development
Prognosis
The long-term outlook for individuals with Leschke syndrome depends on the severity of hormone deficiencies and the timing of intervention. With early diagnosis and appropriate hormone replacement, many individuals can achieve near-normal adult height and undergo normal sexual development. Intellectual outcomes vary and may require additional support. Lifelong endocrine follow-up is often needed to manage hormone therapy and monitor for potential complications.
