A 42-year-old female end-stage renal disease (ESRD) patient with reversible posterior leukoencephalopathy syndrome (RPLS) post-transfusion during initiation of hemodialysis is reported. Eleven days after the onset of illness, we diagnosed encephalopathy as a grand mal seizure resulting from diffuse cerebral edema. One reason for the delayed diagnosis was that her symptom, a throbbing headache that occurred during her first dialysis, indicated dialysis disequilibrium syndrome. We must bear in mind that a small amount of transfusion could cause RPLS even during the first dialysis. To our knowledge, this is the first case report on RPLS after blood transfusion in an ESRD patient.
Introduction and Aims: Deposition of C1q occurs in 0 to 45% of patients with IgAN. In order to identify whether mesangial C1q deposition in IgAN is a novel marker for the response to tonsillectomy plus steroid pulse therapy (TSP), we studied the association between mesangial C1q deposition in IgAN and the remission rate after TSP therapy for IgAN. Methods: We conducted a retrospective cohort study at a single Japanese center. We analyzed data on 110 patients diagnosed with IgA nephropathy who received TSP between January 2003 and December 2012. Positive C1q findings were defined as diffuse mesangial C1q deposition. The study outcome was the resolution of abnormal urinary findings and was defined as negative proteinuria and negative occult blood 1 year after steroid pulse therapy. Results: In all enrolled cases, 69 patients (62.7%) went into remission. Ten out of 24 (41.7%) C1q-positive patients experienced remission, and 59 out of 86 (68.6%) C1q-negative patients experienced remission. Multiple logistic regression model analysis showed that the absence of C1q deposition increased the odds ratio for remission (odds ratio 4.41; 95% confidence interval 1.33-15.75, p = 0.017). Conclusions: These results suggest that the absence of diffuse C1q deposition in the mesangial area of the glomerulus in patients with IgA nephropathy is a positive predictive sign for a response to TSP and is associated with the resolution of urinary abnormalities 1 year after TSP.
In this study, serum iPTH levels were related to administration of ARBs besides gender, age, the presence of DM and serum calcium levels. Our study suggests that the RA system involve serum iPTH levels in uremic patients.
Background The factors that predict baseline peritoneal permeability remain largely unknown. We noticed that patients that adhered to a strict low protein diet (LPD) during the predialysis period seldom showed high peritoneal permeability on the peritoneal equilibration test (PET) at the introduction of peritoneal dialysis (PD). Therefore, we investigated whether a strict LPD during the predialysis period affects peritoneal permeability. Method We retrospectively analyzed 37 patients that started PD in a single Japanese center. Patients were divided into group A and group B by the median amount of daily protein intake (PI) during the predialysis period using urine collected over 24 hours. Results There were no differences between groups A and B in age, gender, proportion of diabetic nephropathy, blood pressure, body mass index, or body surface area. There were also no differences between the groups in laboratory findings, including hematocrit, serum albumin, and serum creatinine. The PETs showed a significantly lower dialysate-to-plasma ratio of creatinine at 4 hours (Cr D/P) for group A than for group B ( p = 0.02). Furthermore, a significant positive correlation between Cr D/P and PI was observed ( r = 0.53, p < 0.01). Conclusion It is suggested that a strict LPD during the predialysis period may suppress peritoneal permeability at induction of PD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
