Brown tumor in a patient with renal failure and secondary hyperparathyroidism

A 28-year-old woman sought care due to an increase in mandible volume lasting approximately 1 year. The patient had chronic kidney disease caused by Berger disease in childhood, and underwent hemodialysis 3 times a week. An intraoral clinical examination revealed an expansive lesion on the left side of the mandible, causing mobility of the adjacent teeth. The radiographic examination showed a lesion of imprecise borders in the region of the right mandible of approximately 2 cm in size. An incisional biopsy and histologic examination revealed a giant cell lesion.

CONCLUSIONS: The effectiveness of cinacalcet were still obviously demonstrated even in chronic HD patients with severe SHPT. In addition, the improvements of bone markers and FGF-23, and stabilization of vascular calcification were observed. Therefore, cinacalcet can provide salutary effects on CKD-MBD in severe SHPT and might be an initially effective PTH-lowering therapy prior to surgical parathyroidectomy as well as an alternative treatment in the patients unsuitable for surgery.

We report here a case of severe SHPT in a hemodialysis patient treated with phosphate binders, calcitriol, and calcimimetics but who still required PTX. Severe hypocalcemia with muscle cramps occurred postoperatively. Around 1 year after PTX, anemia and features of SHPT have improved but the patient still has intermittent hypocalcemia with suspected postoperative hypoparathyroidism. Regular comprehensive assessment of calcium and phosphorus levels throughout all stages of chronic kidney disease is vital. The postoperative period of PTX in SHPT patients is critical, requiring monitoring to improve management.Blood Purif 2017;44(suppl 1):35-40

CONCLUSION: Monitoring PTH levels, early prevention and control of hyperparathyroidism and reducing the concentration of PTH are important means to improve prognosis and delay the progression of chronic kidney disease. Fasudil can restrain EMT induced by PTH; this conclusion provides experimental data for the application of fasudil in the clinical prevention and treatment of renal fibrosis.

Abstract We aim to evaluate the disturbances in mineral metabolism, abnormalities in bone mineral density (BMD), and extraskeletal calcification in newly detected, untreated predialysis stage 4 and 5 chronic kidney disease (CKD) patients at a tertiary care hospital in North India. This is cross-sectional observational study. A total of 95 (68 males, 27 females) newly detected patients underwent clinical evaluation, biochemical assessment [serum calcium, phosphorus, alkaline phosphatase (ALP), albumin, creatinine, intact parathyroid hormone (iPTH), 25- hydroxyvitamin D (25(OH)D)], BMD measurement (at spine, hip, an...

Secondary Hyperparathyroidism (SHPT) requiring parathyroidectomy (PTX) occurs more commonly in patients with progressive chronic kidney disease and in those on long-term lithium therapy. Successful PTX often results in a dramatic drop of parathyroid hormone level, relieves the patient from clinical symptoms, and reduces mortality. However, there is an ongoing debate on the optimal surgical treatment of SHPT. Currently, no clinical guidelines or trials have definitely answered the question of whether Total Parathyroidectomy (TPTX) is superior or equal to Total Parathyroidectomy with Autotransplantation (TPTX  + AT).

Authors: Zhao Y, Zhang LL, Ding FX, Cao P, Qi YY, Wang J Abstract BACKGROUND: Peptidyl-prolyl cis/trans isomerase NIMA-interacting 1 (Pin1) is a key regulator of PTH mRNA stability. Secondary hyperparathyroidism (SHPT), which is characterized by elevated serum PTH levels, is a common complication of CKD. We investigated the possible associations between CKD with SHPT (CKD SHPT) and single-nucleotide polymorphisms of the Pin1 gene and compared the levels of the Pin1 protein in the CKD SHPT patients with those of the controls. METHODS: The study group included 251 CKD SHPT patients and 61 controls. One putative f...

Authors: Chen L, Wang K, Yu S, Lai L, Zhang X, Yuan J, Duan W Abstract Parathyroidectomy (PTx) and medical treatments are both recommended for reducing serum intact parathyroid hormone (iPTH) and curing secondary hyperparathyroidism (sHPT) in patients with chronic kidney disease (CKD), but their therapeutic effects on long-term mortality are not well-known. Thus, we aim to assess such therapeutic effect of PTx. Electronic literatures published on Pubmed, Embase, and Cochrane Central Register of Controlled Trials in any language until 27 November 2015 were systematically searched. All literatures that compared outco...

CONCLUSIONS: Cinacalcet at low doses is effective in the management of SHPT in CKD patients who are not on dialysis. Its use reduces iPTH and calcaemia, without causing serious side effects or significant changes in renal function. PMID: 26906451 [PubMed - as supplied by publisher]
