Multi-organ involvement and intratubular calcium phosphate deposition in the kidney biopsy: what should we investigate?

Background: Anorexia nervosa is frequently associated with alcohol use disorder. Both of them may adversely affect almost every body system, leading to worse clinical outcomes and high mortality risk. Nonetheless, there is little evidence interrelating anorexia nervosa, alcohol use disorder, and kidney failure.

Acute tubulointerstitial nephritis induced by the tyrosine kinase inhibitor vandetanib.

Few cases of immunoallergic tubulointerstitial nephritis associated with tyrosine kinase inhibitors have been described. We describe the first report case associated with vandetanib, a tyrosine kinase inhibitor indicated for the treatment of aggressive and symptomatic medullary thyroid cancer (CMT) in patients with locally advanced or metastatic non-resectable disease.

Fibroblast growth factor 23 (FGF 23) and phosphocalcic metabolism in chronic kidney disease.

Background And Objectives: The ample information available in relation to FGF 23, calcium, phosphorus, PTH, and 25/1,25 vitamin D has allowed us to define consistent values for each variable in each stage of chronic kidney disease (CKD). These values can define early stages, prognostic issues, and new treatment targets. We describe a cross-sectional study of these parameters in patients with different stages of CKD.
