Background: Secondary hyperparathyroidism (SHPT) is a frequent complication of renal disease and most commonly occurs in patients on haemodialysis (HD) with metabolic, vascular, endocrine, and bone complications. The aim of this study was to analyze the evolution of mineral metabolism parameters during the first 36 months of HD treatment and identify the initial factors associated with severe SHPT.
Methods: Serum parathyroid hormone (PTH), calcium and phosphate levels were measured monthly; bone-specific alkaline phosphatase (b-ALP) and beta-CrossLaps (CTX) were measured biannually. Severe SHPT was defined as the need for cinacalcet treatment. Patients with less than 24 months of follow-up were excluded.
Results: One hundred thirty-three incident HD patients were included. Baseline mean PTH was 275 ± 210 pg/mL. After an initial drop at the third month (172 ± 133 pg/mL), the serum PTH level progressively increased to the maximum at 36 months (367 ± 254 pg/mL). This initial drop was associated with the initial correction of both hypocalcaemia and hyperphosphataemia. Serum CTX and b-ALP revealed no significant changes over time. Severe SHPT was observed in 18% of patients and was associated with higher mean calcaemia and phosphataemia. In logistic regression, the initial factors associated with the risk of severe SHPT were: female sex, higher baseline PTH and CTX values. A receiver operation characteristic curve analysis identified a cut-off value of >374 pg/mL for baseline PTH and >1.2 μg/L for CTX for increased risk of developing severe SHPT. The relative risk of developing severe SHPT was 3.7 (1.8-7.5, p = 0.002) for high baseline CTX, 4.9 (2.4-9.7, p = 0.001) for high baseline PTH, and 7.7 (3.6-16, p< 0.0001) when both criteria were present.
Conclusion: After an initial drop, a progressive increase in the serum PTH level during the first 3 years of HD treatment was observed despite aggressive therapy. High baseline levels of PTH and CTX increased the risk of developing severe SHPT.

Background Interest in microwave ablation (MWA) and radiofrequency ablation (RFA) use for treating secondary hyperparathyroidism (SHPT) is rising; however, ablation outcomes in patients with SHPT are not well characterized. Purpose To assess the response of parathyroid hormone (PTH), calcium, phosphorus, and alkaline phosphatase (ALP) levels to US-guided parathyroid MWA and RFA and the safety of these treatments in participants with SHPT. Materials and Methods This prospective multicenter cohort study, conducted from September 2017 to March 2022, included participants with SHPT.

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.

Background: The prevalence of vitamin D deficiency and secondary hyperparathyroidism (sHPT) in adult Fontan patients remains unstudied, and the role of vitamin D and parathyroid hormone (PTH) levels in assessing heart and circulatory failure in these patients is unclear.
Methods: We compared vitamin D deficiency and sHPT prevalence in adult Fontan patients (n = 35; mean age 33 ± 7.5 years) to adults with mild congenital heart disease (ACHD, n = 14).

Introduction: Secondary hyperparathyroidism (sHPT) is a common complication in patients with chronic kidney disease (CKD). Recently, etelcalcetide (EC), an intravenous calcimimetic, has been introduced as a treatment. We evaluated the efficacy of EC in treating sHPT.
