Secondary hyperparathyroidism (SHPT) is common in patients with end-stage kidney disease (ESKD) on kidney replacement therapy, which leads to abnormalities of bone and mineral metabolism. Patients conceiving on kidney replacement therapy add a further layer of complexity to the management of their SHPT. Existing literature in cases of primary hyperparathyroidism (PHPT) has linked untreated hyperparathyroidism to increased maternal and fetal morbidity, including hypertensive disorders of pregnancy, fetal growth restriction and neonatal hypocalcaemia.

Methods: Associations between baseline proteinuria and proteinuria reduction by either irbesartan, amlodipine, or control for similar decrements in blood pressure and the cumulative incidence of renal end points were examined using the Kaplan-Meier method in patients enrolled in the Irbesartan Diabetic Nephropathy Trial.
Results: Risk for kidney failure doubled for each doubling of baseline proteinuria level (hazard ratio, 2.
Background: It is important to know the reliability of early changes in proteinuria in predicting late renal outcomes. The IDNT was a trial in which treatment assignment, baseline and follow-up blood pressure determinations, and albumin/creatinine ratios (ACR), and renal outcomes were recorded.
Methods: Risk of renal outcomes in the IDNT was assessed by proportional hazards modeling as a function of treatment assignment, and achieved systolic blood pressure (SBP) both without, and then with, inclusion of values for baseline proteinuria and early changes in proteinuria.
