Objective To assess the effectiveness of intravenous immunoglobulin G (IVIG) in reducing the need for exchange transfusion in neonates with proven haemolytic disease due to Rh and/or ABO incompatibility. To evaluate the effectiveness of IVIG in reducing the duration of phototherapy and hospital stay. Methods We electronically searched CENTRAL, MEDLINE (1966 to May 2008), EMBASE (1992 to May 2008), CBMdisc (November 1979 to May 2008), and also checked the reference lists of all papers identified. According to the Cochrane Handbook for Systematic Reviews of interventions, randomized controlled trials comparing IVIG and phototherapy with phototherapy alone in neonates with Rh and/or ABO incompatibility were identified and analyzed. Results Six RCTs were included. The meta-analysis showed that, IVIG can significantly decrease the requirements of exchange transfusion (RR=0.27, 95%CI 0.18 to 0.42), the duration of hospitalization (WMD= –1.11, 95%CI –1.60 to –0.63) and the duration of phototherapy (WMD= –0.82, 95%CI –1.16 to –0.47). Conclusions Intravenous immunoglobulin (IVIG) is recommended for treating hemolytic disease of the newborn because it is effective in decreasing the requirements of exchange transfusion, the duration of hospitalization and phototherapy. Well designed studies with large sample in multi-center are required for further proving.
Objective To evaluate the efficacy and safety of different doses of intravenous immunoglobulin (IVIG) in the treatment of relapsing-remitting multiple sclerosis (RRMS). Methods We searched for randomized controlled trials of different doses of IVIG in the treatment of RRMS. We screened the retrieved studies according to the predefined inclusion and exclusion criteria, evaluated the quality of included studies, and performed meta-analyses with The Cochrane Collaboration’s Revman 4.2.0 software. Results Three randomized controlled trials of different dose of IVIG in the treatment of RRMS were included. One was of high quality and the other two were of lower quality. Heterogeneity was identified in one study which reported IVIG in postpartum RRMS. Two studies reported the relapsefree rate and no significant difference was noted between IVIG and placebo. Two studies reported the annual relapse rate, and no significant difference was observed (OR -0.00, 95% CI -0.36 to 0.36, P=0.98). Two studies reported the MRI lesions, and no difference was identified, either. The incidence of adverse events was similar between IVIG and placebo. Conclusion There is insufficient evidence to support the dose-effect relationship of IVIG in the treatment of RRMS. Therefore, an individualized dosing regimen should be applied according to patients’ tolerance and economic status.
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.
ObjectiveTo evaluate the effect of intravenous immunoglobulin (IVIG) on prognosis of patients with idiopathic systemic capillary leakage syndrome (ISCLS). MethodsCase reports and case series related to IVIG on prognosis of ISCLS were electronically searched from the PubMed, CNKI and WanFang Data databases from inception to December 31, 2021. Two researchers screened literature and extracted the data independently, then, prognostic data were analyzed. ResultsA total of 143 case reports (175 patients) and 5 case series (169 patients) were included. About 75% of patients had monoclonal gamma globulin, most of those were IgG κ type. A total of 40 patients received prophylaxis with IVIG, most of whom received a high dose (2 g/kg) of IVIG per month. The 5-year and 10-year survival rates of ISCLS patients receiving IVIG secondary prevention treatment were 96% and 72%, respectively, significantly better than the rates of 66% and 43% in the group without IVIG. The median number of acute episodes per year was 0 (0-20) in the group receiving secondary prevention with IVIG and 2 (1-16) in the group not receiving IVIG. ConclusionHigh-dose (2g/kg) IVIG can improve the long-term survival of ISCLS patients, but efficacy of IVIG in acute episodes is unclear.
