Prognostic role of TNF alpha, LT alpha, MDR1 and codon 72 Tp53 gene polymorphisms on multiple myeloma Egyptian patients.

Leuk Res 2022 Apr 29;117:106854. Epub 2022 Apr 29.

Histology and Cytology Department, Faculty of Science, Mansoura University, Mansoura, Egypt.

Multiple Myeloma (MM) is a type of hematologic malignancies that characterized by uncontrolled plasma cell proliferation. So, the diagnosis depends on the increased numbers of abnormal, immature, or atypical plasma cells in the bone marrow, and many patients present with laboratory abnormalities, such as anemia, hypercalcemia, renal disease, and high protein levels in blood and urine. We aim to analyze the association of some genetic polymorphisms and its effect on the overall survival (OS) among MM patients. Read More

Germline Mutations Related to Primary Hyperparathyroidism Identified by Next-Generation Sequencing.

Front Endocrinol (Lausanne) 2022 28;13:853171. Epub 2022 Apr 28.

Department of Internal Medicine, Endocrine Research Institute, Yonsei University College of Medicine, Seoul, South Korea.

Primary hyperparathyroidism (PHPT) is characterized by overproduction of parathyroid hormone and subsequent hypercalcemia. Approximately 10% of PHPT cases are hereditary, and several genes, such as , , , and , are responsible for the familial forms of PHPT. However, other genetic mutations involved in the etiology of PHPT are largely unknown. Read More

Impaired Mineral Ion Metabolism in a Mouse Model of Targeted Calcium-Sensing Receptor (CaSR) Deletion from Vascular Smooth Muscle Cells.

J Am Soc Nephrol 2022 May 17. Epub 2022 May 17.

School of Biosciences, Cardiff University, Cardiff, United Kingdom

Background: Impaired mineral ion metabolism is a hallmark of CKD-metabolic bone disorder. It can lead to pathologic vascular calcification and is associated with an increased risk of cardiovascular mortality. Loss of calcium-sensing receptor (CaSR) expression in vascular smooth muscle cells exacerbates vascular calcification Conversely, vascular calcification can be reduced by calcimimetics, which function as allosteric activators of CaSR.

Safety and Efficacy of Pamidronate in Neonatal Hypercalcemia Caused by Subcutaneous Fat Necrosis: A Case Report.

Front Pediatr 2022 28;10:845424. Epub 2022 Apr 28.

Neonatal Intensive Care Unit, ASST Grande Ospedale Metropolitano Niguarda, Milan, Italy.

Subcutaneous fat necrosis of the newborn (SCFN) is a panniculitis that develops in fatty areas after fetal or perinatal distress. Prognosis is generally good with complete regression, but it can be complicated by metabolic abnormalities like hypoglycemia, hypertriglyceridemia, thrombocytopenia, and also potentially life-threatening hypercalcemia. Treatments have included hydration, furosemide and corticosteroids. Read More

Long-term efficacy and safety of rifampin in the treatment of a patient carrying a CYP24A1 loss-of-function variant.

J Clin Endocrinol Metab 2022 May 15. Epub 2022 May 15.

University Hospital of Pisa, Endocrine Unit, Pisa, Italy.

Background: Pharmacological therapy may be useful in the treatment of moderate to severe hypercalcemia in patients with infantile hypercalcemia-1 (HCINF1) due to pathogenic variants in the cytochrome P450 24 subfamily A member 1 (CYP24A1). Rifampin is an antituberculosis drug that is a potent inducer of cytochrome P450 3 subfamily A member 4 (CYP3A4), involved in an alternative catabolic pathway of vitamin D. The efficacy of rifampin in improving hypercalcemia was previously reported but many questions remain on the long-term efficacy and safety. Read More

Disorders of the Calcium Sensing Signaling Pathway: From Familial Hypocalciuric Hypercalcemia (FHH) to Life Threatening Conditions in Infancy.

J Clin Med 2022 May 5;11(9). Epub 2022 May 5.

Department of Pediatrics, St. Josef-Hospital Bochum, Ruhr-University Bochum, 44791 Bochum, Germany.

Familial hypocalciuric hypercalcemia (FHH) is a mostly benign condition of elevated calcium and PTH levels based on a hyposensitive calcium sensing receptor () in FHH 1 or its downstream regulatory pathway in FHH2 and FHH3. In children, adolescents and young adults with FHH the main challenge is to distinguish the condition from primary hyperparathyroidism and thereby to avoid unnecessary treatments including parathyroidectomy. However, inheritance of FHH may result in neonatal hyperparathyroidism (NHPT) or neonatal severe hyperparathyroidism (NSHPT), conditions with high morbidity, and in the latter even high mortality.

Multiple Myeloma: 2022 update on Diagnosis, Risk-stratification and Management.

Am J Hematol 2022 May 12. Epub 2022 May 12.

From the Division of Hematology, Mayo Clinic, Rochester, Minnesota.

Disease Overview: Multiple myeloma accounts for approximately 10% of hematologic malignancies.

Diagnosis: The diagnosis requires ≥10% clonal bone marrow plasma cells or a biopsy proven plasmacytoma plus evidence of one or more multiple myeloma defining events (MDE): CRAB (hypercalcemia, renal failure, anemia, or lytic bone lesions) attributable to the plasma cell disorder, bone marrow clonal plasmacytosis ≥60%, serum involved/uninvolved free light chain (FLC) ratio ≥100 (provided involved FLC is ≥100 mg/L), or >1 focal lesion on magnetic resonance imaging.

Risk Stratification: The presence of del(17p), t(4;14), t(14;16), t(14;20), gain 1q, or p53 mutation is considered high-risk multiple myeloma. Read More

Background: Dent disease is an X-linked disorder characterized by low molecular weight proteinuria (LMWP), hypercalciuria, nephrolithiasis and chronic kidney disease (CKD). It is caused by mutations in the chloride voltage-gated channel 5 (CLCN5) gene (Dent disease-1), or in the OCRL gene (Dent disease-2). It is associated with chronic metabolic acidosis; however metabolic alkalosis has rarely been reported. Read More

Ectopic parathyroid hormone as a rare aetiology of hypercalcemia with rhabdomyosarcoma: a new treatment strategy with Zoledronic Acid and Denosumab.

J Pediatr Endocrinol Metab 2022 May 10. Epub 2022 May 10.

Division of Pediatric Endocrinology, Department of Pediatrics, School of Medicine, Kocaeli University, İzmit, Kocaeli, Turkey.

Objectives: Ectopic parathyroid hormone (PTH) secretion is rare in children with rhabdomyosarcoma, and only a few pediatric cases have been reported to date. Reports of the use of Zoledronic Acid (ZA) and Denosumab are limited for the treatment of hypercalcemia of malignancy (HCM) in the pediatric population. The aim of presenting this pediatric case of rhabdomyosarcoma accompanied by HCM, secondary to ectopic PTH secretion, was to highlight the benefits of ZA as a first-choice bisphosphonate in this situation with Denosumab as an alternative therapy.

Novel methods of predicting ionized calcium status from routine data in critical care: External validation in MIMIC-III.

Clin Chim Acta 2022 May 5;531:375-381. Epub 2022 May 5.

Department of Medicine, Veterans Affairs New York Harbor Healthcare System, 800 Poly Place, Brooklyn, NY, USA.

Background: Low ionized calcium (I) is prevalent and prognostic in critical care, but poorly detected by either total calcium (T) or albumin-corrected T (cT). We recently derived models of I (Pred-I) and low I (Prob) in critical care that adjust T for binding to albumin and small anions-represented by the anion gap's components. On internal validation, they outperformed cT in diagnosing low I. Read More

Am J Kidney Dis 2022 May 4. Epub 2022 May 4.

Division of Nephrology, Department of Medicine, University of New Mexico Health Sciences Center, Albuquerque, New Mexico. Electronic address:

Metabolic alkalosis is a widespread acid-base disturbance, especially in hospitalized patients.
