Background: Biochemically monitoring 21-hydroxylase deficiency (21OHD) treatment is challenging. Serum/blood 17-hydroxyprogesterone (17OHP) measurements, especially in the early morning before medication, are traditionally used for this purpose. Urinary pregnanetriol (PT), a urinary metabolite of 17OHP, may also be used. Based on auxological data, we previously reported that the first morning PT value in the range of 2.23.3 mg/gCr is optimal for monitori...

Background: Congenital hypothyroidism (CH) can be categorized into two types: transient CH (group T) and permanent CH (group P). Several studies have recently demonstrated that the levothyroxine (LT4) dosage is useful for predicting LT4 requirement; however, none of the studies followed up their patients to puberty.Objective: To determine the cutoff value for the LT4 dosage as a predictor of LT4 requirement after puberty...
