Abstract

Tubulointerstitial nephritis (TIN) with IgM-positive plasma cells (IgMPC-TIN) is an autoimmune kidney disease characterized by IgM/CD138-double-positive plasma cell infiltration in the tubulointerstitium. A 50-year-old man developed IgMPC-TIN and presented with crystalline inclusions in the rough endoplasmic reticulum. Intracellular crystal formation is a rare finding in paraprotein-related kidney diseases, but this case showed no pathogenic monoclonal immunoglobulin. Prednisolone (PSL, 30 mg) improved the TIN, but PSL tapering resulted in the recurrence of TIN. Combination therapy with 15 mg PSL and 150 mg mizoribine ultimately stabilized TIN. This case offers original evidence concerning the pathophysiology and treatment strategy of IgMPC-TIN.

Abstract

Background : IVC diameter on expiration (IVCdexp) is measured by echocardiography routinely. It is used to estimate volume status and designated as a definitive marker for determining dry weight (DW) in patients undergoing hemodialysis (HD). Methods : A cross-sectional study. Outpatients (n = 107), and inpatients (n = 35) undergoing HD were enrolled. IVCdexp was measured on non-dialysis days in outpatients and dialysis days before and after the dialysis session in inpatients. In outpatients, the relationship of IVCdexp with echocardiography findings and clinical characteristics was analyzed. IVCdexp was compared with the other DW markers as a predictive factor for intradialytic hypotension. In inpatients, IVCdexp was analyzed by dividing inpatients with or without fluid in extravascular space. Results : IVCdexp ranged from 5.4 to 16.9 mm in outpatients who had optimal DW. IVCdexp could reflect on volume status, but not predictive for intradialytic hypotension and not suggestive of fluid in extravascular space. Conclusions : IVCdexp was a rough marker to estimate volume status and only useful in suggesting apparent hypervolemia or hypovolemia. We should know that the IVCdexp value is affected by a lot of factors and not a definitive marker for estimating practical DW.

Abstract

Immune checkpoint inhibitors (ICIs) are becoming a common and important cancer therapy. ICIs are associated with a unique category of side effects, termed immune-related adverse events (irAEs). We herein report the case of a 72-year-old man with postoperative recurrence of lung squamous cell carcinoma who was treated with nivolumab and who developed proteinuria and a worsening kidney function. A kidney biopsy revealed IgA nephropathy. After drug withdrawal, the proteinuria improved and the deterioration of the patient’s renal function was halted. Although renal irAEs are considered to be rare and glomerulonephritis is not typical presentation, physicians need to pay more attention to renal irAEs and glomerular injury.

Abstract

Objective Roxadustat, a hypoxia-inducible factor-prolyl hydroxylase inhibitor, increases the hemoglobin (Hb) levels in patients with chronic kidney disease (CKD). To date, limited clinical studies have focused on the excessive increase in the Hb levels in the early weeks after switching from erythropoiesis-stimulating agents (ESA) to roxadustat in adult non-dialysis patients. We conducted a retrospective study to examine whether early overshoot frequently occurs after switching to roxadustat. Methods This 8-week retrospective pilot study examined patients with anemic, non-dialyzed CKD who switched from ESA (darbepoetin or epoetin beta pegol) to roxadustat or continued ESA. The Hb levels >12.5 g/dL after starting our observation was defined as Hb overshoot. Patients: Twenty-three patients who switched to roxadustat (roxadustat group) and 63 who continued ESA (ESA group) were included. Results The baseline median estimated glomerular filtration rate and mean Hb levels were 15.7 mL/min/1.73 mShizuokax and 10.77 g/dL in roxadustat group and 15.2 mL/min/1.73 m 2 and 10.64 g/dL in ESA group, respectively. Eight patients (34.8%) in the roxadustat group and two patients (3.2%) in the ESA group had Hb overshoot within the 8-week visit (odds ratio: 20.2 [95% confidence interval 3.13-130.0, p<0.01] in the background adjusted model). Among the patients with Hb overshoot in the roxadustat group, the Hb levels were maintained close to baseline 4 weeks after roxadustat discontinuation. A younger age and higher baseline Hb and Hct levels were risk factors for Hb overshoot. Conclusions Hb overshoot was frequently observed in patients switched to roxadustat. Clinicians should be aware of Hb overshoot and emphasize the importance of early Hb level checks.
