Hydroxyurea’s Impact on Ovarian Reserve in SCD

TOPLINE:

Hydroxyurea does not greatly cut ovarian reserve in girls and girls with sickle cell illness. Fertility preservation measures earlier than hydroxyurea medication would possibly maybe merely not be critical.

METHODOLOGY:

• The peep conducted in a pair of French reference companies and products, analyzed ovarian tissue from 76 girls and younger girls with sickle cell illness who underwent ovarian tissue cryopreservation earlier than hematological stem cell transplantation.
• Members had a median age of 10.2 years, with 65.8% being prepubertal. 46.1% had acquired hydroxyurea with a median day-to-day dosage of 23.0 mg/kg and median publicity time of 44 months.
• Histological examination alive to counting and categorizing follicles in accordance with their development stage and calculating follicle densities.
• The major final result used to be to judge the stop of hydroxyurea on primordial follicle density, with secondary analyses on growing follicle density and the influence of vaso-occlusive crises.

TAKEAWAY:

• No critical difference in primordial follicle density used to be stumbled on between hydroxyurea-exposed and hydroxyurea-naive groups (P = .95).
• After adjusting for age, the density of growing follicles used to be marginally lower within the hydroxyurea neighborhood than within the hydroxyurea-naive neighborhood (P = .09).
• No critical affiliation used to be stumbled on between the want of vaso-occlusive crises and primordial follicle density (P = .95).
• The authors concluded that fertility preservation measures earlier than initiating hydroxyurea medication attain not seem critical.

IN PRACTICE:

“Overall, these findings display that ovarian reserve in sickle cell illness used to be not diminished by hydroxyurea medication, transfusion, or vaso-occlusive crisis. Attributable to this truth, ovarian tissue cryopreservation would possibly maybe merely aloof be concept to be a fertility preservation choice earlier than gonadotoxic medication.”

SOURCE:

The peep used to be led by Tamara Diesch-Furlanetto, University of Basel Youngsters’s Clinical institution in Basel, Switzerland. It used to be printed online in Blood Advances.

LIMITATIONS:

One limitation of the peep is the absence of anti-Mullerian hormone level measurements at the time of ovarian tissue cryopreservation, which impedes correlation with follicle density. Additionally, the prolonged hydroxyurea wash-out interval, especially in those with cerebral vasculopathy, makes it tense to plan conclusions about the influence on growing follicles. The peep also lacked a wholesome alter neighborhood for comparability, making it untimely to attain that follicle density in sickle cell illness sufferers is typical.

DISCLOSURES:

No linked conflicts of hobby were disclosed by the authors. The peep used to be supported by grants from the root Stiftung für krebskranke Kinder, Regio Basiliensis, Basel, Switzerland, and SNF scientific change, Bern, Switzerland. Additional disclosures are necessary within the distinctive article.
