Rationale:POEMS syndrome is a rare multi-system disorder, which sometimes involves the kidney. Immunotactoid glomerulopathy (ITG) is an uncommon glomerular disease resulted from deposits of immunoglobulins and its derivatives. ITG caused by POEMS syndrome is rarely reported.Patient concerns:A 63-year-old man was presented with acute kidney injury. In addition, it's found that he had abnormal serum free κ /λ ratio, polyneuropathy, Castleman's disease, organomegaly, endocrinopathy and skin changes.Diagnoses:POEMS syndrome was diagnosed, Renal biopsy revealed an ITG.Interventions:Dexamethasone and thalidomide were given, as well as hemodialysis and other supportive treatments.Outcomes:The patient's extrarenal manifestations improved gradually and his renal function also showed slight improvement.Lessons:ITG caused by POEMS syndrome is rare, however, it makes sense that the monoclonal proteins produced by the plasma cells could cause ITG. Chemotherapy similar to that employed in multiple myeloma may be beneficial for these patients.
Introduction:The impact of vitamin B metabolic disorders on hemodialysis (HD) patients' survival is unknown. This study is to investigate the association of serum vitamin B1, B3, B5, and B6 with all-cause and cardiovascular (CV) mortality in HD patients.Methods: Patients' baseline serum vitamin B1, B3, B5, and B6 levels were collected, and they were followed up for the occurrence of all-cause and CV death. Kaplan-Meier analysis and Cox proportional hazards model were used to examine the association of vitamin B with mortality. Results: Seventy-six HD patients were included. The median follow-up time was 99 months. Kaplan-Meier analysis showed that baseline vitamin B5 < 69.0 nmol/L and vitamin B6 < 8.1 ng/ml were associated with a higher risk of CV mortality, but these associations were nullified after adjustment. Conclusions: Serum vitamins B1, B3, B5, and B6 were not associated with all-cause or CV mortality in HD patients.
