Abstract

OBJECTIVE To evaluate the clinical effect of high-dose intravenous immunoglobulin (HDIVIG) single dose and pulse therapy combined with small-dose prednisone acetate in the treatment of patients with Kawasaki disease (KD). METHODS Eighty patients with KD from Baoding Children's Hospital, China, were randomly divided into two groups: the experimental group and the control group, each with 40 cases. Patients in the experimental group were treated with HDIVIG single dose, pulse therapy combined with low-dose prednisone acetate, while patients in the control group were treated with conventional-dose immunoglobulin. Patients in both groups were treated with aspirin orally, and given symptomatic treatment including anti-inflammatory, nutritional support, correction of water and electrolyte disturbance and acid-base balance. Peripheral venous blood samples were drawn from all patients at the time of admission, Day-1, Day-7 and Day-14 after treatment, and in the basic state of getting up in the morning, and then the levels of tumor necrosis factor (TNF-a), C-reactive protein (CRP), interleukin-6 (IL-6) and other inflammatory factors were detected by enzyme-linked immunosorbent assay (ELISA). The time of body temperature falling to normal, lymph node swelling recovery, hands and feet swelling, mucosal hyperemia regression after treatment in the two groups was recorded, and the treatment effect of the two groups was comprehensively evaluated. RESULTS After treatment, the levels of inflammatory factors such as TNF-a, CRP, IL-6 in the experimental group were significantly lower than those in the control group, with a statistically significant difference (P<0.05). In addition, the time of body temperature falling to normal, lymph node swelling recovery, hands and feet swelling, and mucosal hyperemia regression in the experimental group was significantly shorter than that in the control group (p=0.00). The effective rate of the experimental group was 95% and that of the control group was 80%, with a statistically significant difference (p=0.04). CONCLUSION HDIVIG single dose, pulse therapy combined with small-dose prednisone acetate has a favourable therapeutic effect in the treatment of patients with KD, by which the inflammatory factors can be significantly improved, clinical symptoms and weight can be quickly ameliorated, and therapeutic effect can be enhanced.

Abstract

BACKGROUND Standard first-step therapy for Kawasaki disease consists of Intravenous immunoglobulin and high dose Aspirin (80-100 mg/kg/day). The standard dose of Intravenous immunoglobulin (2gr/kg) is strongly effective in reducing the risk of coronary arteries abnormalities. So, the proper dose and efficacy of Aspirin to decrease the risk of coronary arteries abnormalities is a controversial issue. In this study, it is tried to assess the result of eliminating high-dose Aspirin in the treatment of the acute phase of Kawasaki and observe the incidence rate of coronary arteries abnormalities when only Intravenous immunoglobulin was administered. METHODS This study is a prospective randomized, open-label, blinded end-points clinical trial performed in Afzalipour hospital in Kerman University of Medical Sciences from September 2017 to September 2018 in 62 patients with typical and atypical Kawasaki disease. The study group received Intravenous immunoglobulin (2 g/kg) and the control group get the same dose of Intravenous immunoglobulin plus Aspirin with the dose of 80-100 mg/Kg/day until they were afebrile for 48 hours. Afterward, both groups received a daily single dose (3-5 mg/kg) of Aspirin for six weeks. Echocardiography was done after two weeks, six weeks, and six months. Internal diameter of the left and right main coronary arteries was measured and then the corresponding Z-score was calculated. RESULTS In the study group, coronary arteries abnormalities decreased from 38.7% in the 2nd week to 16.1% in the 6th month. In the control group, it declined from 54.8% to 22.6%. There was no statistically significant difference between the groups in term of frequency of abnormal coronary arteries at the study period (P=0.151). CONCLUSIONS We concluded that high dose Aspirin does not have a significant role in preventing coronary arteries abnormalities in Kawasaki disease and giving standard 2 gr/kg/day Intravenous immunoglobulin without high-dose Aspirin in acute-phases therapy does not increase the risk of coronary arteries abnormality.

Abstract

OBJECTIVE To perform a systematic review and meta-analysis on the efficacy and safety of intravenous (IVIg) and subcutaneous (SCIg) immunoglobulin (Ig) therapy in the treatment of idiopathic inflammatory myopathy (IIM) and juvenile dermatomyositis (JDM). METHODS PubMed, Embase and SCOPUS were searched to identify studies on Ig therapy in patients with IIM and/or JDM (2010-2020). Outcome measures were complete response (CR) or partial response (PR) in terms of muscle power and extramuscular disease activity measures on the International Myositis Assessment and Clinical Studies Group (IMACS) core set domains. RESULTS Twenty-nine studies were included (n = 576, 544 IIM, 32 JDM). Muscle power PR with pooled Ig therapy was 88.5% (95% confidence interval (CI): 80.6-93.5, n = 499) and PR with SCIg treatment was 96.61% (95% CI: 87.43-99.15, n = 59). Pooled PR with first-line use of IVIg was 77.07% (95% CI: 61.25-92.89, n = 80). Overall, mean time to response was 2.9 months (95% CI: 1.9-4.1). Relapse was seen in 22.76% (95% CI: 14.9-33). Studies on cutaneous disease activity and dysphagia showed significant treatment responses. Glucocorticoid and immunosuppressant sparing effect was seen in 40.9% (95% CI: 20-61.7) and 42.2% (95% CI: 20.4-64.1) respectively. Ig therapy was generally safe with low risk of infection (1.37%, 95% CI: 0.1-2.6). CONCLUSIONS Add-on Ig therapy improves muscle strength in patients with refractory IIM, but evidence on Ig therapy in new-onset disease and extramuscular disease activity is uncertain.

Abstract

BACKGROUND High-dose intravenous immunoglobulin (IVIG) is the mainstay of treatment for Kawasaki disease (KD). Usually, 2 g/kg of IVIG is administered over 10-24 h, depending on the institution or physician, but the association between infusion speed and effectiveness has not been reported. In this study, we evaluated the differences in efficacy and safety between two different IVIG administration speeds. METHODS This was a multicenter, unblinded, randomized controlled study. Patients newly diagnosed with KD were randomized into two groups: one who received IVIG over 12 h (12H group, double speed), and one that received IVIG over 24 h (24H group, reference speed). The endpoints included the duration of fever, incidence of coronary artery abnormalities (CAAs) and of adverse events. Laboratory data were evaluated before and after IVIG administration. RESULTS A total of 39 patients were enrolled. There was no difference between groups in fever duration after the initiation of IVIG (21 h vs. 21.5 h, p = 0.325), and no patient experienced CAAs. Two adverse events were observed in the 12H group (elevation of aspartate aminotransferase and vomiting), however no severe adverse events requiring treatments or extension of hospital stay were observed in either group. After initial IVIG administration, the change ratio of inflammatory markers, such as white blood cell counts, neutrophils, C-reactive protein, and albumin, did not show significant differences between the two groups. On the other hand, a greater increase of serum immunoglobulin G from its baseline level was observed in the 24H group compared to the 12H group (3037 ± 648 mg/dl vs. 2414 ± 248 mg/dl, p < 0.01). CONCLUSION The efficacy and safety of IVIG administered over 12 h (double speed) were similar to those administered over 24 h (reference speed).

Abstract

BACKGROUND For many chronic immune system disorders, the available treatments provide several options for route of administration. The objective of this systematic literature review is to inform discussions about therapy choices for individual patients by summarizing the available evidence regarding the preferences of patients with chronic immune system disorders for intravenous (IV) or subcutaneous (SC) administration. METHODS Searches of the MEDLINE, Embase and Cochrane Library databases were conducted using terms designed to capture studies reporting patient preferences between IV and SC therapy published in English. Relevant studies were limited to those in which mode of administration, including treatment frequency and setting, was the main difference between comparators. RESULTS In total, 49 studies were included in the review. Among 18 studies that compared IV and SC immunoglobulin therapy, 16 found patients to prefer the SC administration route. The results of the 31 studies comparing IV infusion and SC injection of non-immunoglobulin therapies were mixed, with patients favoring SC administration in 20, IV infusion in seven, and having no overall preference in four. Patient experience had a strong effect on preferences, with treatment-experienced patients preferring their current administration route in most studies. Patients preferring SC administration tended also to prefer treatment at home, mainly due to the convenience and comfort of home treatment and the avoidance of having to attend hospital. By contrast, patients preferring IV infusion tended to cite the lower treatment frequency and a dislike of self-injecting, and preferred hospital treatment, mainly due to the presence of healthcare professionals and resulting feelings of safety. CONCLUSION In general patients with chronic immune system disorders tend to be more likely to choose SC administration than IV infusion, but preferences may vary according among individuals. These findings may assist discussions around appropriate treatment choices for each patient.

Abstract

Objective: This study aimed to identify the clinical features of Kawasaki disease shock syndrome (KDSS) in children. Methods: The case-control studies of KDSS and KD children up until April 30, 2021 were searched in multiple databases. The qualified research were retrieved by manually reviewing the references. Review Manager 5.3 software was used for statistical analysis. Results: The results showed that there was no significant difference in the incidence of male and female in children with KDSS. Children with KDSS compared with non-shocked KD, there were significant difference in age, duration of fever, white blood cell (WBC) count, percentage of neutrophils (NEUT%), platelet count (PLT), c-reactive protein level (CRP), alanine transaminase concentration (ALT), aspartate transaminase concentration (AST), albumin concentration (ALB), sodium concentration (Na), ejection fraction, and length of hospitalization as well as the incidence of coronary artery dilation, coronary artery aneurysm, left ventricular dysfunction, mitral regurgitation, pericardial effusion, initial diagnosis of KD, intravenous immunoglobulin (IVIG) resistance and receiving second dose of IVIG, vasoactive drugs, hormones, and albumin. In contrast, there was no difference in the hemoglobin concentration, erythrocyte sedimentation rate, and the incidence of conjunctival injection, oropharyngeal change, polymorphous rash, extremity change, and incomplete KD. Conclusion: Current evidence suggested that the children with KDSS had more severe indicators of inflammation and more cardiac abnormalities. These patients were resistant to immunoglobulin treatment and required extra anti-inflammatory treatment. Systematic Review Registration: PROSPERO registration number CRD42021241207.

Abstract

Aspirin was once believed to reduce the mortality of Kawasaki disease (KD) due to its effect on the thrombotic occlusion of coronary arteries. However, conflicting evidence has been found regarding aspirin treatment and its benefit in patients with acute KD. We compared the efficacy of different aspirin doses in acute KD. A literature search of PubMed, EMBASE, and Cochrane databases was conducted to identify studies comparing different doses of aspirin for acute KD. The primary outcome of interest was coronary artery lesions (CAL). We used random-effects network meta-analysis. Six retrospective studies, including 1944 patients receiving aspirin in doses of 0, 3-5, 30-50, or 80-100 mg/kg/day, were selected. The risks of CAL were not significantly different for the various doses of aspirin compared to the placebo: odds ratio (OR) was 1.10 [95% confidence interval (CI): 0.70-1.71] for patients with aspirin 3-5 mg/kg/day; OR = 1.23 (95% CI: 0.67-2.26) for aspirin 30-50 mg/kg/day, and OR = 1.59 (95% CI: 0.74, 3.421) for 80-100 mg/kg/day. The P-score ranged from 0.76 for placebo to 0.19 for aspirin 80-100 mg/kg/day. The different doses of aspirin exhibited no significant difference with regard to the efficacy of CAL or with the secondary outcomes of intravenous immunoglobulin resistance or hospital stays for acute KD. Therefore, we found that treatment without any aspirin is not inferior to other doses of aspirin and can also slightly reduce the risk of CAL.

Abstract

BACKGROUND Mucous membrane pemphigoid (MMP) is an autoimmune disease, which can lead to fibrosis of mucous membranes and functional impairment. Biologic agents should be explored as alternative treatment options to improve outcomes. OBJECTIVE To conduct a systematic review of biologic treatment outcomes in patients with MMP. METHODS MEDLINE and EMBASE search was conducted on July 23(rd), 2020 to include 63 studies using PRISMA guidelines. RESULTS Use of IVIG (n=154), rituximab (n=112), TNFα inhibitors (n=7), and combination treatments (n=58) were reported in 331 patients with MMP. IVIG led to complete resolution in 61.7% (n=95/154) of patients within 26.0 months, with a recurrence rate of 22.7% (n=35/154) and headache as the most common side effect (8.4%, n=13/154). Rituximab led to complete resolution in 70.5% (n=79/112) of patients within 8.7 months, with a recurrence rate of 35.7% (n=40/112). Most commonly reported side effects were urinary tract infections (4.5%, n=5/112), leukocytopenia (2.7%, n=3/112), death due to severe infections (1.8%, n=2/112). TNFα inhibitors led to complete resolution in 71.4% (n=5/7) of patients within 3.9 months of treatment, without reported adverse events. CONCLUSIONS Randomized clinical trials with long term follow up are required to conclude the promising safety and efficacy of biologic agents in MMP patients.

Abstract

BACKGROUND Coronary artery lesion (CAL) caused by Kawasaki disease (KD) is a leading cause of acquired heart disease in children. Initial treatment of intravenous immunoglobulin (IVIG) can reduce the incidence of CAL. Although most of the current studies have shown a certain correlation between CAL and IVIG resistance, the conclusions are not completely consistent. Thus, we performed this meta-analysis to evaluate the association between IVIG resistance and CAL in KD. METHODS PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, and China National Knowledge Infrastructure through April 21, 2020 were searched to detect relevant studies. Data analysis was performed with STATA 15.1. RESULTS A total of 53 relevant studies were eligible to this analysis, including 30312 KD patients, of which 4750 were IVIG resistance and 25562 were responders. There was a significant difference found between IVIG resistance and IVIG response groups in the incidence of CAL (P < 0.001, odds ratio (OR), 3.89; 95% confidence interval (CI) (3.18, 4.75)). The heterogeneity test results showed that the I2 value was 74.8%. The meta-regression analysis showed that the study regions might be the sources of heterogeneity. The subgroup analysis suggested that the incidence of CAL in the IVIG resistance group was still higher than that in the IVIG response group under different regions, IVIG resistance diagnostic criteria, CAL diagnostic criteria, and study types. Meanwhile, the sensitivity analysis did not find any significant impact from every single study. CONCLUSIONS This is the first meta-analysis to reveal the incidence of CAL was associated with IVIG resistance in KD patients. Further well-designed studies with uniform criteria are needed to evaluate the incidence of CAL in IVIG resistant patients.

Abstract

The present study aimed to review the relevant studies in order to determine the efficacy of infliximab (IFX) in the treatment of Kawasaki disease (KD). The relevant studies were retrieved using the PubMed, Cochrane and Embase databases. Key sources in the literature were reviewed; all articles published by July 2019 were considered for inclusion. For each study, odds ratios, mean difference and 95% confidence interval (95% CI) were assessed to evaluate study outcomes. A total of 16 studies involving 429 patients were relevant to the questions of interest of the current meta-analysis. Compared with intravenous immunoglobulin (IVIG), IFX or IFX plus IVIG significantly reduced the incidence of adverse events, including the number of patients with fever, changes in lip and oral cavity and/or cervical lymphadenopathy. The white blood cell (WBC), neutrophil and C-reactive protein (CRP) levels were also reduced in the IFX or IFX plus IVIG group compared with those in the IVIG or polyethylene glycol-treated human immunoglobulin (VGIH) groups. The platelet counts, alanine aminotransferase (ALT) levels and Z-scores were increased in the IFX or IFX plus IVIG groups compared with those in the IVIG or VGIH groups. In the single-arm studies, the incidence of coronary artery aneurysm was 0.150 (95% CI: 0.024, 0.277), the non-response rate was 0.097 (95% CI: 0.056, 0.138), and the incidence of adverse events was 0.156 (95% CI: 0.122, 0.190). IFX not only effectively reduced the incidence of fever, conjunctival injection, changes in lip and oral cavity and cervical lymphadenopathy polymorphous exanthema, but also the WBC, neutrophil, ALT and CRP levels. The platelet levels were increased in patients after the IFX therapy compared with patients in the IVIG or VGIH groups. IFX or IFX plus IVIG exhibited improved clinical efficacy in the treatment of KD compared with that of IVIG or VGIH. However, as a limited number of studies was included in the current study, the findings should be verified further.
