Objective We searched for evidence on mycophenolate mofetil(MMF) as a treatment for patients with diffuse proliferative lupus nephritis. Methods We attempted to find the current best evidence by searching The Cochrane Library(Issue 4, 2005), MEDLINE(1990 to June 2007), CMB(1980 to December 2006), CNKI(1979 to October 2007). We critically appraised the available evidence. Results Four systematic reviews and 6 randomized controlled trials of high quality were available. MMF and prednisolone were found to be an effective continuous induction-maintenance treatment for diffuse proliferative lupus nephritis. MMF was associated with less drug toxicity. Conclusion Given the current evidence and our clinical experience, and considering the patient and the values and preferences of his family,MMF was given at 1 g daily in combination with steroids at the beginning. No obvious adverse effects occurred during 3 months of follow-up.
ObjectiveTo investigate the diagnosis, clinical features, treatment and outcome of pure red cell aplasia (PRCA) caused by human parvovirus B19 (HPV-B19) infection in kidney recipients. Method The clinical courses of six patients with PRCA caused by HPV-B19 infection after renal transplantation in West China Hospital between May 2018 and April 2019 were retrospectively investigated. Results The six patients showed obvious anemia symptoms, lacking rash, joint pain and other clinical symptoms of viral infection. The hemoglobin level of five patients got totally remission from a course of intravenous immunoglobulin (IVIG) treatment, and anemia symptoms like fatigue, weakness got notable improvement. One patient had no improvement after two courses of IVIG treatment, and his anemia was significantly improved after the third IVIG course combined with immunosuppressant conversion(from tacrolimus to cyclosporine), and one patient with recurrence accepted a repeated course of IVIG treatment and obtained remission of severe anemia again. The median time of reticulocyte firstly rose to above 0.084×1012/L from the day of IVIG treatment ended was 3.50 (1.25, 5.00) days, and the median time required for a 30 g/L increase in hemoglobin to the end of IVIG treatment was 16.00 (9.25, 31.25) days. No serious adverse reactions occurred and all patients had stable graft function. Conclusions The main clinical manifestations of PRCA caused by HPV-B19 infection after kidney transplantation are anemia symptoms, lacking other clinical symptoms of viral infection. HPV-B19 DNA detection combined with blood routine examination, reticulocyte count and bone marrow cytology (or none) can diagnose HPV-B19 infection. High dose of IVIG is effective and safe, and a repeated course is still effective when the infection recurs. For refractory PRCA that IVIG monotherapy fail, a combination with conversion from tacrolimus to cyclosporine can effectively improve the anemia without graft dysfunction.

Objective To explore the medical insurance quota payment of dialysis treatment for outpatients with end-stage renal disease in Chengdu from following aspects, evaluation indexes and reasonable amount, so as to provide scientific basis for the payment of single disease. Methods A questionnaire survey was conducted to collect the cost information of patients, and to formulate the assignment of evaluation indexes according to the therapeutic principles and statistical results; Delphi method was adopted to determine the assignment and the standard of quota payment. Results A total of 17 dialysis organizations approved by Chengdu municipal medical insurance were involved in this study. Of 700 questionnaires distributed, 686 were retrieved. After excluding 26 questionnaires for incomplete filling and incorrect treatment information, a total of 660 questionnaires were included actually, accounted for 94.28% of all informants. The results of survey showed that, the hemodialysis treatment rate accounted for 84% (555/660) of all informants, while the peritoneal dialysis treatment rate accounted for 16% (105/660). By assessing the project assignment of outpatient dialysis treatment, the minimum annual payment of hemodialysis was RMB 118 242.75 yuan, while that of peritoneal dialysis was RMB 96 498.00 yuan. Conclusion The quota payment of outpatient dialysis shows b evidence after adopting the treatment project assignment. The grading quota payment of outpatient dialysis enables the medical insurance fund to be more reasonably used.
Objective To evaluate the effectiveness and safety of reduced glutathione in the treatment of acute renal failure. Methods Twenty-three patients with acute renal failure were divided into the treatment group (n=10) and the control group (n=13) by simple randomisation. Patients in the treatment group received intravenous reduced glutathione 1200 mg daily. Patients in the control group were not treated with reduced glutathione. The therapeutic course for both groups was 4 weeks. Serum creatinine and urea nitrogen were determined before treatment as well as at the end of each of the 4 weeks. Proximal and distal renal tubular functions were evaluated at the end of the treatment. The time when clinical symptoms were improved was recorded and adverse drug reactions were monitored. Results The durations of nausea and vomiting as well as the oliguria stage were shorter in the treatment group than in the control group. The serum creatinine level in the treatment group decreased more markedly than that in the control group. At the end of the treatment, the renal tubular function was better in the treatment group than in the control group. Conclusion Reduced glutathione contributes to the early recovery of renal function in patients with acute renal failure. However, more high-quality and large-scale randomized controlled trials are needed.
Objective To investigate the efficacy and safety of polyethersulfone highflux dialyzer for uremic patients. Methods Forty eligible uremic patients were randomized into two groups, i.e. polyethersulfone (PES) group and polysulfone(PSF) group, according to a random number table. The PES group received hemodialysis for 4 hours with polyethersulfone highflux dialyzer (Chengdu OCI Medical Device Co., Ltd), and the PSF group with polysulfone highflux dialyzers (Fresenius Polysulfones, Fresenius Medical Care, Bad Homburg, Germany). Changes in serum creatinine, urea, β2-microglobulin, hemoglobin and albumin levels were determined for efficacy and safety evaluation. Results All the 40 patients completed the trial. The serum creatinine, urea, β2-microglobulin levels of all the patients in the two groups decreased (gt;30%) after the hemodialysis with different highflux dialyzers, and no significant difference was observed between the two groups (Pgt;0.05). Changes in solute clearance index (KT/V) value, hemoglobin and albumin levels were also comparable between the two groups (Pgt;0.05). Conclusions The efficacy and safety of the PES hollow fiber membrane hemodialyzer is equivalent to that of the PSF hemodialyzer in hemodialysis for uremic patients.

Methods Fifteen patients with lupus nephritis (LN), 3 patients with membranoproliferative glomerulonephritis (MPGN) and 3 patients with membranous nephropathy (MN) who failed the previous immunosuppressive therapy from May 2008 to March 2010 in our hospital were treated with multitarget therapy. The initial dose of prednisone was 30-40 mg/d and then tapered gradually. MMF and FK506 were started at 0.5 g/d or 1 mg/d, and the target blood concentration of the two drugs was 20-40 mg/(h·L) and 5-8 ng/mL respectively. Clinical parameters such as liver and renal function, urine protein, and side effects were recorded and analyzed in the regular follow-up. Results After 6 months of treatment, 7 (46.7%) of the 15 LN patients achieved complete remission (CR), 5 (33.3%) achieved partial remission (PR), while 3 (20%) failed this treatment and had no response (NR). All of the three MPGN patents had NR to this combined therapy. Two (66.7%) of the 3 MN patents achieved PR while 1 (33.3%) had NR. No patient withdrew or died because of side effects. One patient developed upper respiratory infection, one experienced alopecia, two developed gastrointestinal syndrome and three experienced gradual increasing in the serum creatinine. Conclusion Multitarget therapy with FK506, MMF and steroid is an effective and safe therapy for refractory lupus nephritis and it can be used in patients who are resistant to the conventional immunosuppressive therapy. However, this combined therapy does not meet a satisfactory result in patients with MN and MPGN, which entails further study.
Objective To understand the preventive effect of pneumatic compression therapy on deep vein thrombosis (DVT) in lower limbs of patients with spinal cord injury. Methods Patients with spinal cord injury who transferred from Orthopedics Department to Rehabilitation Department undergoing rehabilitation in the First Affiliated Hospital of University of Science and Technology of China and discharged from April 2017 to December 2020 were retrospectively included. According to the contents of the medical order of the case data, the patients were divided into treatment group and control group. The intervention method of the treatment group was pneumatic compression therapy and conventional rehabilitation treatment, and the control group was conventional rehabilitation treatment. Multivariate logistic regression was used for statistical analysis to explore the association of pneumatic compression therapy and the risk of DVT in patients with spinal cord injury. Results Finally, 153 patients were enrolled, including 71 cases in the treatment group and 82 cases in the control group. After rehabilitation therapy, DVT occurred in 10 cases (14.1%) in the treatment group and 21 cases (25.6%) in the control group. There was no significant difference in incidence of DVT between the two groups (χ2=3.129, P=0.077). After six months of follow-up, DVT occurred in 11 cases (15.5%) in the treatment group and 12 cases (14.6%) in the control group. There was no significant difference in incidence of DVT between the two groups (χ2=0.022, P=0.822). D-dimer [odds ratio (OR) =1.104, 95% confidence interval (CI) (1.036, 1.175), P=0.002] and age [OR=1.081, 95%CI (1.040, 1.124), P<0.001] were independent risk factors for the risk of DVT after treatment. Pneumatic compression therapy was a protective factor for the risk of DVT [OR=0.210, 95%CI (0.075, 0.591), P=0.003]. Age [OR=1.057, 95%CI (1.008, 1.108), P=0.023] was an independent risk factor for the risk of DVT after six months. The effect of pneumatic compression therapy was not statistically significant (P=0.393). Conclusions After spinal cord injury, it is necessary to strengthen the management of high serum D-dimer state, especially the risk of DVT in elderly patients. Pneumatic compression therapy could be used as a treatment measure to reduce risk of DVT in patients with spinal cord injury during hospitalization, however, the preventive effect after half a year needs to be further studied.
