Background: Sodium-glucose cotransporter 2 (SGLT2) inhibitors have been shown in clinical trials to increase serum Mg levels in patients with type 2 diabetes mellitus. However, it is unclear whether this effect is similarly observed in patients with chronic kidney disease (CKD) and whether such an increase is observed immediately after treatment.

Methods: Our retrospective observational study included the 62 patients with CKD who started SGLT2 inhibitor therapy at our institution between 2017 and 2022 and who had complete data on serum Mg measurements at baseline and at 1, 3, and 6 months after treatment.

A 34-year-old Japanese man presented with blurred vision, headache, nausea, anemia, thrombocytopenia, and severe renal dysfunction. Thrombotic microangiopathy was initially suspected to have been caused by malignant hypertension. Antihypertensive medications did not improve his thrombocytopenia or renal dysfunction, and other diseases causing thrombotic microangiopathy were ruled out.

Introduction: We previously reported that fibroblast growth factor 23 (FGF23)-klotho signaling plays a role in B cell immunity. Despite high serum levels of FGF23, a decline in immunity is frequently observed in patients on hemodialysis (HD); thus, abnormalities in the FGF23-klotho signaling pathway in immune cells may occur in these patients.

Methods: We analyzed the number of klotho-positive cells in peripheral blood mononuclear cells from 10 male and 6 female patients on HD and 5 healthy male subjects using flow cytometry.

A 74-year-old man underwent intravesical bacillus Calmette-Guerin (BCG) therapy for bladder cancer and later presented with lower left back pain. Magnetic resonance imaging of the spine showed high signal intensity, diagnosed as a cystic lesion in the epidural and bilateral intestinal psoas muscle. A computed tomography-guided needle biopsy and histological examination revealed bacteria from the family Mycobacteriaceae, and Mycobacterium bovis was identified using multiplex polymerase chain reaction.

Background: Vascular calcification is significant because of the close association between the degree of vascular calcification and cardiovascular mortality in chronic kidney disease (CKD) patients.

Summary: There are 2 types of vascular calcification in CKD patients. One is endothelial vascular calcification, a common type of vascular calcification.
