Figure 1. Clinical findings and responses to PTH infusion in ADH1 patients.
Panel A shows clinical characteristics and treatments for all six unrelated ADH1 patients (P1-P6). aM, male; F, female. bS, seizures; NC, nephrocalcinosis; RI, renal impairment; BC, bilateral cataracts; BS, Bartter syndrome; H, hyperinsulinism. cReceived phenobarbitone anticonvulsant therapy. df, familial; dn, de novo; c, constitutively active. eNormal ranges: adjusted-calcium, 2.20-260 mmol/L; phosphate, 1.30-2.60 mmol/L (<1 month), 1.30-2.40 mmol/L (1 month-1 year), 0.90-1.80 mmol/L (1-16 years), 0.80-1.50 mmol/L (>16 years); magnesium, 0.70-1.0 mmol/L; creatinine, 27-77 μmol/L (<1 month), 14-34 μmol/L (<1 year), 15-31 μmol/L (1-3 years), 23-37 μmol/L (3-5 years), 25-42 μmol/L (5-7 years), 30-47 μmol/L (7-9 years), 29-56 μmol/L (9-11 years), 39-60 μmol/L (13-15 years), 40-68 μmol/L (>15 years); parathyroid hormone (PTH) 1.6-6.9 pmol/L; urine calcium: creatinine (Ca:Cr) ratio, <1.50 mmol/mmol (0-1 years), <1.25 mmol/mmol (1-2 years), <1.0 mmol/mmol (2-5 years), <0.70 mmol/mmol (5-10 years), <0.60 mmol/mmol (10-18 years). fCSPI, continuous subcutaneous PTH(1-34) infusion; NA, not available; gMg, magnesium; K, potassium; T, thiazide, Di, diazoxide; Do, doxazosin; Fe, ferrous fumarate; Epo, erythropoietin. All children were taking cholecalciferol or ergocalciferol. Panel B shows effects of CSPI compared to prior therapy with oral calcium supplements and vitamin D analogs (Ca+D) on serum concentrations of adjusted-calcium; phosphate; calcium-phosphate product (Ca x Pi); and magnesium. Number of serum biochemical values per treatment group in each patient (P1-P6) are shown below respective box and whisker plot. Panel C shows effects of CSPI compared to prior therapy with Ca+D (Pre-CSPI) on numbers of seizures per month and hospital admissions per month, in six ADH1 patients (P1-P6).
