The negative impact of levothyroxine treatment on urinary luteinizing hormone measurements in pediatric patients with thyroid disease
Demir, And; Bober, Ece; Darcan, Sukran; Aydin, Adem; Stenman, Ulf-Hakan; Buyukgebiz, Atilla; Hero, Matti (Frontiers Media Sa, 2023)Objectives: Previous studies suggest urinary luteinizing hormone (LH) and follicle-stimulating hormone (FSH) measurements by immunofluorometric assays (IFMA) as noninvasive alternatives to serum assays for puberty assessment. ... -
A Novel Case of Lipoatrophy Due to a Non-Pegylated Long-Acting Growth Hormone Somatrogon
Buyukgebiz, Atilla; Demir, And (Karger, 2024)[No abstract available] -
Quantification of overnight urinary gonadotropin excretion predicts imminent puberty in girls: a semi-longitudinal study
Demir, And; Buyukgebiz, Atilla; Aydin, Adem; Hero, Matti (Springer Int Publ Ag, 2023)PurposeWe explored the alternative of using overnight fold change in gonadotropin levels by comparing the last-night-voided (LNV) and first-morning-voided (FMV) urine concentrations of luteinizing hormone (LH) and ... -
Severe Lipoatrophy in a Growth Hormone Deficient Toddler Girl Treated with a Non-Pegylated Long-Acting Growth Hormone
Buyukgebiz, Atilla; Demir, And (Mdpi, 2025)Background: Recombinant growth hormone (rhGH) has been used since 1985 to treat growth hormone (GH)-induced short stature, typically associated with transient adverse events. However, lipoatrophy, characterized by irreversible ... -
Thematic Review of Endocrine Disruptors and Their Role in Shaping Pubertal Timing
Demir, And; Aydin, Adem; Buyukgebiz, Atilla (Mdpi, 2025)This review examines the inconsistent effects of endocrine-disrupting chemicals (EDCs) and pollutants on pubertal timing, emphasizing the methodological challenges contributing to variability in findings. Data from nine ... -
Urine Sampling Protocol Recommendations for Reliable Determination of Total Urinary Luteinizing Hormone Immunoreactivity in the Pediatric Population
Demir, And; Aydin, Adem; Buyukgebiz, Atilla (Mdpi, 2023)This study investigates day-to-day variations in urinary luteinizing hormone (U-LH) concentrations in children, focusing on potential minimization or correction methods. 95 children and adolescents (51 boys, 44 girls, ages ...
