Purpose
Serum soluble interleukin-2 receptor level is a sensitive and quantitative marker of lymphocyte activation. We determined levels of serum soluble interleukin-2 receptor in children with reflux nephropathy to evaluate its clinical significance in the prediction for the progression of renal injuries.Materials and Methods
Serum soluble interleukin-2 receptor values were determined in 63 children with reflux nephropathy. The group consisted of 37 boys and 26 girls 10 to 18 years old. T cells (naive and memory), B cells and macrophages were evaluated immunohistochemically in the scarred kidneys of 4 other patients (3 boys and 1 girl 5 to 16 years old) who underwent nephrectomy due to severe reflux nephropathy with little function seen on99m technetium-dimercapto-succinic acid (DMSA) renal scan. Levels of serum soluble interleukin-2 receptor were measured by an enzyme-linked immunosorbent assay. We simultaneously determined serum levels of creatinine and beta 2-microglobulin, and urinary levels of alpha 1-microglobulin and microalbumin. Individual functions of the right and left kidneys were estimated by renal dimercaptosuccinic acid uptake.Results
Levels of serum soluble interleukin-2 receptor in the patients who had low total uptake of DMSA (right uptake plus left uptake) were significantly higher than those from patients with normal total uptake. Levels of serum soluble interleukin-2 receptor correlated significantly with levels of creatinine (r=0.616, p <0.0001) and beta 2-microglobulin (r=0.803, p <0.0001), and levels of urinary alpha 1-microglobulin (r=0.753, p <0.0001) and microalbumin (r=0.673, p <0.0001). A significant negative correlation was observed between levels of serum soluble interleukin-2 receptor and total DMSA uptake values (right uptake plus left uptake r= −0.678, p <0.0001). In the scarred kidneys leukocyte infiltrates were markedly increased in fibrosed spaces. The predominant cell type in these lesions was memory T cells.Conclusions
These results suggest that elevated levels of serum soluble interleukin-2 receptor are likely to reflect activated T cells in the kidneys of patients with reflux nephropathy and may be a useful predictor of progression of renal injury in these children. 相似文献72.

Previous investigations have suggested that ghrelin, an endogenous orexigenic peptide, is involved in the pathology of eating disorders. We conducted a study to determine whether any preproghrelin gene polymorphisms are associated with eating disorders. Three hundred thirty-six eating disorder patients, including 131 anorexia nervosa (AN)-restricting types (AN-R), 97 AN-binge eating/purging types (AN-BP) and 108 bulimia nervosa (BN)-purging types (BN-P), and 300 healthy control subjects participated in the study. Genotyping was performed to determine the polymorphisms present, and with this information, linkage disequilibrium (LD) between the markers was analyzed and the distributions of the genotypes, the allele frequencies, and the haplotype frequencies were compared between the groups. The Leu72Met (408 C > A) (rs696217) polymorphism in exon 2 and the 3056 T > C (rs2075356) polymorphism in intron 2 were in LD (D' = 0.902, r2 = 0.454). Both polymorphisms were significantly associated with BN-P (allele-wise: P = 0.0410, odds ratio (OR) = 1.48; P = 0.0035, OR = 1.63, for Leu72Met and 3056 T > C, respectively). In addition, we observed a significant increase in the frequency of the haplotype Met72-3056C in BN-P patients (P = 0.0059, OR = 1.71). Our findings suggest that the Leu72Met (408 C > A) and the 3056 T > C polymorphisms of the preproghrelin gene are associated with susceptibility to BN-P. 相似文献

Background
The aim of this study was to investigate patient characteristics on admission to hospital that increase the risk of subsequent mechanical ventilation (MV) use for patients with Guillain–Barré syndrome (GBS).Methods
We extracted data from the Japanese Diagnosis Procedure Combination (DPC) database for 4132 GBS patients admitted to hospital. Clinical characteristics of GBS patients with and without MV were compared. Multivariate logistic regression analyses were performed to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for the associations of requirement for MV with coexisting infectious diseases, after adjustment for potential confounding variables, age, sex, hospital type, and ambulance transportation.Results
In total, 281 patients required MV, and 493 patients had coexisting respiratory diseases on admission. After adjustment for covariates and stratification by coexisting respiratory diseases, multivariate logistic regression analysis revealed that coexisting cytomegaloviral (CMV) disease (OR 8.81; 95% CI, 2.34–33.1) and herpes simplex viral (HSV) infections (OR 4.83; 95% CI, 1.16–20.1) were significantly associated with the requirement for MV in the group without coexisting respiratory diseases.Conclusion
Our findings suggest that coexisting CMV and HSV infections on admission might be significantly associated with increased risk of respiratory failure in GBS patients. 相似文献75.

We experienced a case of relapse of proteinase 3-specific antineutrophil cytoplasmic autoantibody (C-ANCA)-associated rapid progressive glomerulonephritis (RPGN) in a patient after renal transplantation. A 19-yr-old man, who underwent a living donor kidney transplantation, presented a rapid renal function deterioration along with a sign of infection. Initially he was treated as acute rejection, but renal function did not improve. Renal biopsy revealed crescentic glomerulonephritis, and C-ANCA titer was 12 EU/mL, resulting in the diagnosis of C-ANCA-associated RPGN. He was treated with three consecutive methylprednisolone pulses twice in addition to the basal immunosuppressive medications (cyclosporine A and mizoribine), then his renal function improved to normal. Bearing the possibility of recurrence of glomerulonephritis in mind, we re-evaluated the nature and disease course of renal failure of original kidney. He experienced a rapid deterioration of renal function in 1992, and eventually CAPD was started in 1992. His serum in 1992 revealed high titer of C-ANCA (24 EU/mL), and renal biopsy performed in 1992 showed a crescentic glomerulonephritis. Taken together, we diagnosed this event as a relapse of C-ANCA-associated GN. Lessons from our experience are: 1) steroid pulse and high-dose corticosteroid therapy may be useful for the treatment of relapse of C-ANCA-associated GN patients after renal transplantation; 2) the possibility of a relapse of C-ANCA-associated GN following renal transplantation has to be kept in mind, especially when infection precedes the deterioration of allograft kidney function. 相似文献

Objective
Neuro-feedback (NFB) training by the self-regulation of slow potentials (SPs) <0.5?Hz recorded from the vertex scalp has been applied for seizure suppression in patients with epilepsy. However, SP is highly susceptible to artifact contamination, such as the galvanic skin response (GSR). This study aimed to evaluate the correlation between SPs recorded from the scalp and intracranial electroencephalography (EEG) by event-related coherence analysis.Methods
The scalp and subdural SPs were simultaneously recorded during NFB training by the DC-EEG machine while undergoing invasive recordings before epilepsy surgery in 10 patients with refractory partial epilepsy. The SPs at the vertex electrode were used as a reference for coherence analysis.Results
The coherence of SPs negatively correlated with the distance between the subdural and scalp electrodes. A significant negative correlation was noted between the linear subdural–scalp electrode distance and the coherence value (r?=????0.916, p?<?0.001).Conclusion
Scalp-recorded SPs from the vertex area primarily reflect the cortical activity of high lateral convexity.Significance
Our results strongly suggest that SPs in NFB recorded from the vertex scalp electrode is derived from the cortices of high lateral convexity but not from the artifacts, such as GSR. 相似文献78.

To determine the clinical characteristics of hepatitis B virus (HBV) reactivation in patients undergoing interferon‐free antihepatitis C virus (HCV) therapy, we examined HBV DNA in 25 HBV co‐infected patients and 765 patients with resolved HBV infection during and after treatment with direct‐acting antiviral agents (DAAs). Among those with HCV genotype 1, asunaprevir plus daclatasvir was administered to 160 patients, sofosbuvir (SOF) plus ledipasvir to 438 patients and paritaprevir plus ombitasvir and ritonavir to 25 patients. In total, 167 patients with genotype 2 were treated with SOF plus ribavirin. Three patients with an HBV DNA level ≥2000 IU/mL were treated with entecavir before anti‐HCV therapy, without reactivation of HBV. In 3 of 22 (12%) HBV surface antigen (HBsAg)‐positive patients with an HBV DNA level <2000 IU/mL, the viral load increased during treatment. However, hepatitis flare did not occur in these patients. There was no significant difference in clinical history between patients with and without HBV reactivation. Among 765 patients with resolved HBV infection, HBV reactivation occurred in 1 (0.1%) patient after initial resolution, whose HBV DNA level spontaneously decreased after DAA therapy. We compared anti‐HBs titres at baseline with those at post‐DAA therapy in 123 patients without HBsAg. There was no significant difference in anti‐HBs levels between the two points (P = .79). In conclusion, HBV reactivation was rare in HBsAg‐negative patients treated with DAA therapy. Additionally, hepatitis did not occur in HBV‐reactivated patients with a baseline HBV DNA level <2000 IU/mL before DAA therapy. 相似文献

Background: Previous small studies conducted around 2000 suggested an association between the use of angiotensin-converting enzyme inhibitors (ACEIs) and a reduction in post-stroke aspiration pneumonia (AP) in Japan. However, it is unclear whether receiving ACEIs can reduce post-stroke AP in the current clinical environment, where stroke management has been improved. This study aimed to re-evaluate the preventive effect of ACEIs on post-stroke AP, compared with that of angiotensin II receptor blockers (ARBs). Methods: Using the Japanese Diagnosis Procedure Combination database, we identified patients who were hospitalized for stroke and developed AP during hospitalization from July 2010 to December 2016. After applying the exclusion criteria, we performed 1:1 propensity score matching between patients receiving ACEIs and those receiving ARBs after discharge. The outcomes were 14-day, 30-day, and 90-day readmission for post-stroke AP among patients with stroke who had AP during their initial hospitalization. Cox regression was performed to analyze these readmissions. Results: In total, 35,586 eligible patients were identified. Of these patients, 5846 (16%) received ACEIs. Propensity score matching created 5789 pairs. No significant difference was seen in 14-day readmission (0.7% versus 0.8%), 30-day readmission (1.3% versus 1.3%), or 90-day readmission (2.4% versus 2.6%) between the ARB and ACEI groups. The hazard ratio of the ACEI group compared with the ARB group was not significant (1.21; 95% confidence interval: 0.98-1.48). Conclusions: In this retrospective nationwide study, ACEIs could not be concluded to have a preventive effect on post-stroke AP in the current clinical environment. 相似文献
