Background: Clinical characteristics and follow-up outcomes were examined in Korean patients with lipoid congenital adrenal hyperplasia (LCAH) enrolled in the Multicenter Networks for Ideal Outcomes of Pediatric Rare Endocrine and Metabolic Disease (OUTSPREAD) cohort. Methods: Thirty-one patients (classic LCAH C-LCAH, n=29; nonclassic LCAH NC-LCAH, n=2) from 10 centers were included. NC-LCAH was defined by any of the following: 46,XY karyotype with male external genitalia, no fludrocortisone use, or diagnosis after infancy. Results: Median age at diagnosis was 36.5 days (interquartile range IQR, 14.6 to 120.5); salt-wasting occurred in 58.6% of patients, and skin hyperpigmentation was the most common clinical feature (71%). All C-LCAH patients (STAR variants: p.Q258*/p.Q258* n=27, p.Q258*/p.Arg182His n=1, p.Q258*/p.Arg182Cys n=1; karyotypes: 46,XX n=17, 46,XY n=12) were diagnosed in infancy with a female phenotype. Among C-LCAH patients with 46,XX, 10 had spontaneous thelarche (median, 11.0 years; IQR, 8.2 to 12.2) and five reached menarche (median, 12.4 years; IQR, 11.9 to 13.2). Among eight C-LCAH-XX patients who underwent ultrasonography, three had ovarian cysts, including one rupture. Two NC-LCAH patients (p.Q258*/p.Val187Met and p. Ala218Val/p.Gly221Ser; both 46,XY) were diagnosed at 1.6 and 3.3 years with male external genitalia; one had spontaneous puberty at 10.6 years. Eight patients reached adult height (Z-score, 0.1; IQR, -0.9 to 1.2). The hydrocortisone dose was 21.7 mg/m2 (IQR, 14.9 to 26.5) at diagnosis and 17.3 mg/m2 (IQR, 13.9 to 22.7) at last follow-up (median age, 11.6 years; IQR, 8.9 to 17.4). Conclusion: This is the first large-scale multicenter investigation in Korea reporting long-term outcomes of LCAH. Continued longitudinal follow-up focusing on pubertal development and reproductive outcomes is warranted.
