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: The clinical diagnosis of x-linked hypophosphatemic (XLH) rickets is based on a number of biochemical observations. These include a reduction in the percentage of tubular reabsorption of phosphate (%TRP), and in the maximal tubular phosphate reabsorption capacity corrected for glomerular filtration rate (TmP/GFR). However, it is important to maintain sufficient renal blood flow in order to accurately calculate TmP/GFR.Objective: The aims of t...
