PGNMID and anti-CD38 monoclonal antibody: a therapeutic challenge.

Monoclonal gammopathy of renal significance (MGRS) designates disorders induced by a monoclonal protein secreted by plasma cells or B-cell clones in patients who do not meet the diagnostic criteria for multiple myeloma or other B-cell malignancies. Proliferative glomerulonephritis with monoclonal immunoglobulin deposits (PGNMID) is a form MGRS. Until now, no guidelines to decide the best therapeutic approach to manage PGNMID exist, and most patients progress to End Stage Renal Disease (ESRD) without therapy.

[Renal biopsy practice in Piedmont and Valle d'Aosta].

In 2010 a questionnaire was administered to the renal units of Piedmont and Valle d'Aosta to analyze their procedures for renal biopsy (RB). Seventy-eight percent of units performed RBs, 57% for more than 20 years, but only 43% performed at least 20 BRs per year. 20/21 units performed RB in an inpatient setting and 1/21 in day hospital with the patient remaining under observation the night after.

Role of caspofungin in restoring the impaired phagocyte-dependent innate immunity towards Candida albicans in chronic haemodialysis patients.

Phagocyte-dependent cellular immunity in chronic kidney disease patients undergoing haemodialysis treatment is frequently impaired owing to the uraemic state, resulting in an intrinsic susceptibility to developing invasive fungal infections with high mortality rates. Since synergism between phagocytic cells and antifungal drugs may be crucial for successful therapy, the aim of this study was to evaluate the effects exerted by caspofungin (CAS) on the functional activities of polymorphonuclear cells (PMNs) in haemodialysed patients (HDs) towards Candida albicans compared with those of PMNs from healthy subjects (HSs). PMNs were separated from venous blood samples of 66 HDs and 30 HSs (as controls), and measurement of phagocytic and intracellular fungicidal activities of HD-PMNs and HS-PMNs was performed in the presence of CAS at the minimum inhibitory concentration (MIC) and at sub-MICs.

[Application of guidelines in clinical practice: a multicenter analysis of the treatment of membranous glomerulonephritis in Piedmont, Italy].

The treatment of membranous glomerulonephritis (MGN) is controversial, especially in cases of no response to first-line treatment or multiple relapses. The Clinical Nephrology Group of Piedmont carried out a multicenter analysis of the treatment of patients affected by MGN in 15 nephrology units in Piedmont. The first treatment is usually started after a waiting period of 3-6 months in case of proteinuria in the nephrotic range but normal or slightly impaired renal function.
