An Effective Outcome Despite Delayed Treatment Initiation in a Female With Kallmann Syndrome: A Case Report

Area of Science:

• Reproductive Endocrinology
• Genetics
• Clinical Medicine

Background:

• Kallmann syndrome (KS) is characterized by hypogonadotropic hypogonadism and anosmia due to GnRH deficiency.
• Diagnosis in females typically occurs around age 15 due to primary amenorrhea, leading to hormone replacement therapy (HRT).
• Limited data exists on the efficacy of delayed HRT in females with KS.

Observation:

• A rare case of a female with KS diagnosed and treated at age 27 is presented.
• The patient initiated HRT after a significant delay in diagnosis.

Findings:

• Following HRT initiation, the patient exhibited increased uterine size, bone mineral density, and breast development over two years.
• These positive outcomes demonstrate that HRT remains effective despite delayed treatment.
• Therapeutic benefits became evident within a two-year timeframe.

Implications:

• This case highlights that HRT can be successfully initiated later in life for females with KS.
• The findings suggest that delayed treatment does not preclude positive therapeutic responses.
• These insights may inform management strategies for other patients with congenital hypogonadotropic hypogonadism and delayed treatment initiation.
