Immunoglobulin Failure and Retreatment in Kawasaki Disease

Several cases of Kawasaki disease (KD) were unresponsive to the initial treatment with intravenous immunoglobulin (IVIG). We retrospectively analyzed all children admitted with KD to determine the occurrence and variables associated with the initial IVIG treatment failure. All patients who fulfilled the criteria for KD and were treated with a single dose (2 g/kg) of IVIG between January 1995 and August 2001 were enrolled. An analysis of the patients who had initially failed to respond to IVIG was performed. A total of 120 patients were enrolled during the study period. There were 68 boys (56.7%). Fourteen patients (11.6%) were found to be unresponsive to initial IVIG treatment. Patients who were anemic (Hb<10 G/DL), HAD A HIGH NEUTROPHIL COUNT (> 75%), a high band count, and low albumin were at risk of failure to respond to a single dose of IVIG. We found no correlation among age, gender, days since starting IVIG treatment, and erythrocyte sedimentation rate (ESR) with failure of the initial IVIG treatment. There were 12 patients (10%) who developed coronary artery aneurysms. The failure of a single dose of IVIG treatment occured in up to 11.6% of our Kawasaki patients. We found that low hemoglobin (<10 G/DL), HIGH NEUTROPHIL COUNT (> 75%), high band count, and a low albumin were associated with the requirement for retreatment with a second dose of IVIG.     

N-terminal Pro-Brain Natriuretic Peptide (NT proBNP) as a Predictive Indicator of Initial Intravenous Immunoglobulin Treatment Failure in Children With Kawasaki Disease: A Retrospective Study

Intravenous immunoglobulin (IVIG) administered in the acute stage of Kawasaki disease (KD) is the standard therapy. Few reports describe nonresponders to initial treatment with IVIG in KD, which remains the most consistent risk factor for coronary artery lesions (CALs). This study aimed to investigate whether the serum level of N-terminal pro-brain natriuretic peptide (NT-proBNP) can be a predictive indicator for identifying patients with KD at higher risk of IVIG treatment failure. In this study, 135 patients with a diagnosis of KD admitted for IVIG treatment were retrospectively enrolled for analysis. Of these 135 patients, 22 were nonresponders who received additional rescue therapy because they had an elevated body temperature 36 h after completion of initial IVIG treatment. The NT-proBNP concentration was significantly higher in the nonresponder group (2,465.36 ± 3,293.24 pg/mL) than in the responder group (942.38 ± 1,293.48 pg/mL) (p < 0.05). The optimal sensitivity and specificity cutoff point for predicted nonresponders was 1,093.00 pg/mL or higher. The sensitivity and specificity for prediction of IVIG response were respectively 70.0 and 76.5 %. The findings show that NT-proBNP is a helpful marker in determining patients at risk for not responding to initial IVIG treatment. The authors suggest that patients with an NT-proBNP level of 1,093.00 pg/dL or higher are likely to fail initial IVIG and may require further rescue therapy.     

The relationship of eosinophilia to intravenous immunoglobulin treatment failure in Kawasaki disease

To investigate the role of eosinophils in Kawasaki disease (KD) and the relationship to initial intravenous immunoglobulin (IVIG) treatment failure. A retrospective analysis of all children who were admitted and met the criteria of KD between 1999 and 2005. The patients were divided into IVIG-responsive and IVIG-resistant groups. A total of 185 patients were enrolled during the study period. A series of blood eosinophils and biochemistry studies were correlated to the effectiveness of IVIG. The neutrophils percentage before IVIG treatment (pre-IVIG), leukocyte counts within 3 days after IVIG treatment (post-IVIG), liver enzyme, albumin levels, and post-IVIG eosinophils percentage were all significantly different between the two groups in univariate analysis. Under multivariate analysis with logistic regression, post-IVIG eosinophilia [peripheral blood (PB) eosinophils >or=4%] had an inverse correlation to KD patients with IVIG-resistance (p = 0.003). Also, pre-IVIG hypoalbuminemia (albumin 相似文献   

Marker of T‐cell activation is elevated in refractory Kawasaki disease

Background: The aim of this study was to investigate whether T‐cell activation is involved in the pathogenesis of Kawasaki disease (KD) resistant to intravenous immunoglobulin (IVIG) treatment. Methods: Serum samples were obtained from 27 patients who fulfilled the diagnostic criteria for KD. These 27 patients were divided into three groups according to their responses to IVIG: Group A, nine patients who showed no response to either initial IVIG or additional IVIG; Group B, six patients who did not respond to initial IVIG but did respond to additional IVIG; Group C, 12 patients who responded to initial IVIG. Serum samples were obtained before and after initial IVIG. Using a commercial chemiluminescence enzyme immunoassay, we examined the serum levels of two cytokines related to T‐cell activation and the severity of inflammation: soluble interleukin‐2 receptor and interleukin‐6. Results: There were no significant differences in the serum levels of the two cytokines before initial IVIG among the three groups, but significant intergroup differences were evident after initial IVIG in the serum levels of soluble interleukin‐2 receptor (P < 0.01, Group A > C) and interleukin‐6 (P < 0.01, Group A > B > C). Conclusions: Our results show that marker of T‐cell activation is elevated most markedly in KD patients resistant to both initial and additional IVIG, and suggest that T cells may be activated in refractory KD.

Intravenous immune globulin plus corticosteroids in refractory Kawasaki disease

Background: The aim of the present study was to investigate the efficacy of i.v. immune globulin (IVIG) therapy combined with corticosteroids for additional treatment of acute Kawasaki disease (KD) unresponsive to initial IVIG treatment. Methods: In 50 prospective KD patients, six IVIG non‐responders without clinical improvement within 24–48 h after completion of initial IVIG, received 2 g/kg IVIG concurrently with 2 mg/kg i.v. prednisolone sodium succinate (PSL) until normalization of C‐reactive protein level. Treatment was then changed to oral PSL, which was tapered over time. Clinical and coronary artery lesion (CAL) outcomes were compared with those of 13 IVIG non‐responders who received additional heterogeneous therapies in 125 retrospective KD patients. In addition, the scoring system of Kobayashi et al. for prediction of non‐responsiveness to initial IVIG treatment was retrospectively verified in 175 KD subjects, consisting of 50 prospective and 125 retrospective patients in order to evaluate the efficacy of the re‐treatment regimen. Results: Incidence of CAL in the study patients was lower than in the control patients, although differences were not significant both in the acute stage (within 1 month: 1/6, 16.7% vs 7/13, 53.8%; P= 0.177) and in the convalescent stage (after 1 month: 0/6, 0.0% vs 4/13, 30.8%; P= 0.255). According to the non‐responder prediction system, the scores of six study and 13 control patients before initial IVIG treatment were similar (7.2 ± 1.9 vs 5.3 ± 3.1; P= 0.200). No serious adverse effects related to each treatment were noted in patients of either group. Conclusions: Additional IVIG combined with concurrent PSL appears to be safe and worth evaluation for the treatment of acute KD unresponsive to initial IVIG treatment.     

A multicenter prospective randomized trial of corticosteroids in primary therapy for Kawasaki disease: clinical course and coronary artery outcome

OBJECTIVE: To investigate the role of corticosteroids in the initial treatment of Kawasaki disease (KD). STUDY DESIGN: Between September 2000 and March 2005, we randomly assigned 178 KD patients from 12 hospitals to either an intravenous immunoglobulin (IVIG) group (n = 88; 1 g/kg for 2 consecutive days) or an IVIG plus corticosteroid (IVIG+PSL) group (n = 90). The primary endpoint was coronary artery abnormality (CAA) before a 1-month echocardiographic assessment. Secondary endpoints included duration of fever, time to normalization of serum C-reactive protein (CRP), and initial treatment failure requiring additional therapy. Analyses were based on intention to treat. RESULTS: Baseline characteristics of groups were similar. Fewer IVIG+PSL patients than IVIG patients had a CAA before 1 month (2.2% vs 11.4%; P = .017). The duration of fever was shorter (P < .001) and CRP decreased more rapidly in the IVIG+PSL group than in the IVIG group (P = .001). Moreover, initial treatment failure was less frequent (5.6% vs 18.2%; P = .010) in the IVIG+PSL group. All patients assigned to the IVIG+PSL group completed treatment without major side effects. CONCLUSIONS: A combination of corticosteroids and IVIG improved clinical course and coronary artery outcome without causing untoward effects in children with acute KD.     

Analysis of potential risk factors associated with nonresponse to initial intravenous immunoglobulin treatment among Kawasaki disease patients in Japan

BACKGROUND: Some Kawasaki disease (KD) patients do not respond to initial treatment with intravenous immunoglobulin (IVIG). The purpose of this study was to determine potential risk factors associated with IVIG nonresponse among KD patients in Japan. METHODS: Data were obtained from questionnaires used for the 18th nationwide KD survey of patients who visited hospitals in Japan from 2003 through 2004. Data for patients who met the case definition for KD and received 2 g/kg single infusion IVIG as the initial treatment within 10 days of illness were analyzed. IVIG nonresponders were defined as patients who needed secondary treatment after initial IVIG administration. RESULTS: Among 15,940 KD patients in Japan during 2003-2004, 6330 patients received 2 g/kg single infusion IVIG within 10 days of illness onset. IVIG nonresponders accounted for 20.3% of them (n = 1286). Male sex [odds ratio (OR), 1.21, 95% confidence interval (CI), 1.06-1.37], receipt of the initial IVIG before the fifth day of illness (OR: 1.89, 95% CI: 1.66-2.15), and having recurrent KD (OR: 1.38, 95% CI: 1.00-1.90) were significantly associated with IVIG nonresponse. In addition, IVIG nonresponders had significantly higher risks for coronary artery aneurysms (OR: 10.38, 95% CI: 6.98-15.45) or giant coronary artery aneurysms (OR: 54.06, 95% CI: 12.84-227.65). CONCLUSIONS: Physicians should consider potential IVIG nonresponse among recurrent KD patients or KD patients diagnosed and treated before the fifth day of illness, particularly if they are boys and have laboratory values associated with nonresponse such as low platelet count, and elevated alanine aminotransferase and C-reactive protein. Some of these patients may benefit from administration of the alternative secondary treatment early during the illness along with the initial IVIG treatment.     

Steroid Pulse Therapy for Children With Intravenous Immunoglobulin Therapy–Resistant Kawasaki Disease: A Prospective Study

Patients with Kawasaki disease (KD) who did not respond to the initial IVIG are known to have higher risk for developing coronary arterial lesions (CALs). Our aim is to clarify whether patients with initial IVIG resistant KD may benefit from methylprednisolone pulse therapy (MPT) in comparison with re- treatment of IVIG (2nd IVIG). A total of 237 patients (median age: 2 years 2 months; range 1 months–10 years) with KD were initially treated with IVIG (2 g/kg). Among them, 41 patients (22 %) were assessed as IVIG resistance: these patients were allocated to either group A receiving MPT (n = 14) or group B receiving the 2nd IVIG (n = 27). Patients with resistant to the additional therapy (MPT or 2nd IVIG) were received second IVIG (group A) or MPT (group B). Changes in leukocyte count, C-reactive protein and albumin before and after an additional therapy were significantly greater in group A than those in group B. However, the prevalence of CALs did not differ between the groups (36 % in group A and 26 % in group B, p > 0.05). There was no significant difference in the medical cost between the groups (median cost: 92,032 JPY in group A and 97,331 JPY in group B). MPT does not reduce the risk of development to CAL and does not seem to be beneficial as single agent therapy for IVIG resistant KD.     

Assessment of Risk Factors for Korean Children with Kawasaki Disease

Kawasaki disease (KD) is the most common cause of acquired heart disease in children. Intravenous immunoglobulin (IVIG) is the standard therapy for KD, but more than 10% of KD patients do not respond to IVIG and are at high risk for the development of coronary artery lesions (CALs). To identify clinical and genetic risk factors associated with CAL development and IVIG nonresponsiveness, this study analyzed the clinical data for 478 Korean KD patients. Multivariate logistic regression analysis showed that incomplete KD, IVIG nonresponse, fever duration of 7?days or longer, and the CC/AC genotypes of the rs7604693 single nucleotide polymorphism (SNP) in the PELI1 gene were significantly associated with the development of CALs, with odds ratios (ORs) ranging from 2.06 to 3.04. The risk of CAL formation was synergistically increased by the addition of individual risk factors, particularly the genetic variant in the PELI1 gene. Multivariate analysis also showed that a serum albumin level of 3.6?g/dl or lower was significantly associated with nonresponsiveness to IVIG [OR, 2.76; 95% confidence interval (CI), 1.34-5.68; P?=?0.006]. Conclusively, incomplete KD, IVIG nonresponsiveness, long febrile days, and the rs7604693 genetic variant in the PELI1 gene are major risk factors for the development of CALs, whereas low serum albumin concentration is an independent risk factor for IVIG nonresponsiveness.     

Prediction of the Risk of Coronary Arterial Lesions in Kawasaki Disease by Brain Natriuretic Peptide

Kawasaki disease (KD) is an acute systemic vasculitis associated with the development of coronary arterial lesions (CALs) occurring in 3–5% of children treated by intravenous immune globulin (IVIG). However, a considerable number of patients who are not responding to IVIG are at much higher risk. Although studies have explored potential biomarkers to predict patients with KD who are at risk of CAL, no useful single marker exists. We hypothesized that the serum concentrations of the N-terminal moiety of brain natriuretic peptide (NT-proBNP) can be useful to predict CAL. Forty-three children with KD (29 males and 14 females) were enrolled in this study. Despite IVIG, 6 of the 43 patients developed CAL. There were, however, no significant differences in variables between children with CAL and those without CAL: These include age, gender, day of the illness, leukocyte count, and the serum levels of sodium, C-reactive protein, and albumin. The serum NT-proBNP level was significantly higher in children with CAL than those without CAL (2,611 ± 1,699 vs. 1,073 ± 1,427 pg/ml; P = 0.03): the cutoff value of 1,000 pg/ml to predict CAL produced a specificity of 0.68, sensitivity of 0.83, and an odds ratio as high as 10.4. In conclusion, NT-proBNP is increased in KD patients who are developing CAL, and patients with an elevated serum NT-proBNP >1,000 pg/ml have a risk of CAL ~10 times higher than that of patients with a modest increase.     

川崎病患儿治疗前后血清脂源性细胞因子的变化及意义

目的 检测急性期川崎病患儿静脉注射丙种球蛋白（IVIG）治疗前后血清中脂源性细胞因子Omentin-1和Chemerin浓度变化及意义。方法 选取2015年1月至2019年4月确诊为川崎病患儿60例为研究对象,同时选取40例健康儿童和40例急性感染性疾病患儿分别作为健康对照组和感染对照组。根据是否对IVIG治疗敏感将川崎病患儿分为IVIG敏感组（n=51）和IVIG不敏感组（n=9）;根据是否合并冠状动脉损害（CAL）将川崎病患儿分为合并CAL组（n=13）和不合并CAL组（n=47）。ELISA法检测川崎病患儿IVIG治疗前后及两对照组儿童血清Omentin-1和Chemerin水平。结果 川崎病患儿血清Omentin-1和Chemerin水平均明显高于健康对照组和感染对照组（P < 0.05）。经过48 h治疗后,IVIG敏感组患儿血清Chemerin水平较治疗前明显降低（P < 0.05）,血清Omentin-1水平在IVIG敏感组患儿治疗前后比较差异无统计学意义（P > 0.05）。治疗前,IVIG不敏感组患儿血清Chemerin水平明显高于IVIG敏感组（P < 0.05）;合并CAL组血清Chemerin水平明显高于不合并CAL组;而血清Omentin-1水平在IVIG敏感与不敏感组间及合并CAL与不合并CAL组间比较差异均无统计学意义（P > 0.05）。结论 川崎病患儿血清中高表达的Chemerin和Omentin-1可能参与川崎病的发生和发展;Chemerin可能参与川崎病所致CAL过程,且血清Chemerin水平可能成为临床预测IVIG敏感性的新监测指标。

川崎病治疗前发热时间与丙种球蛋白耐药的相关性临床研究北大核心CSCD

目的 探讨川崎病(Kawasaki disease,KD)患儿丙种球蛋白(intravenous immunoglobulin,IVIG)治疗前发热时间与IVIG耐药的关系。方法 回顾性收集2018年1月至2020年12月收治KD患儿317例的病例资料,根据IVIG治疗前发热时间分为短热程组(发热时间≤4 d,n=92)和长热程组(发热时间>4 d,n=225),根据是否发生IVIG耐药将每组再分为耐药组和非耐药组。分析比较不同热程耐药组及非耐药组的基线资料及实验室结果,并采用多因素logistic回归分析IVIG耐药的影响因素。结果 短热程组中IVIG耐药19例(20.7%),并发冠状动脉瘤5例(5.4%);长热程组中IVIG耐药22例(9.8%),并发冠状动脉瘤19例(8.4%);短热程组IVIG耐药率明显高于长热程组(P<0.05),而冠状动脉瘤发生率在两组间差异无统计学意义(P>0.05)。短热程组中,耐药患儿治疗前血钠水平低于非耐药患儿,而降钙素原、C反应蛋白及N末端B型利钠肽原水平则明显高于非耐药患儿(P<0.05)。长热程组中,耐药患儿治疗前血钠及肌酸激酶水平低于非耐药患儿(P<0.05)。多因素logistic回归分析显示,血钠水平降低与长热程组KD患儿IVIG耐药有关(P<0.05)。结论 KD患儿IVIG耐药因IVIG治疗前发热时间不同而异。在治疗前发热时间>4 d的KD患儿中,血钠降低与IVIG耐药具有相关性。     

Variations in the Number of CCL3L1 Gene Copies and Kawasaki Disease in Korean Children

High-dose intravenous immunoglobulin (IVIG) therapy is the highly effective and standard treatment for Kawasaki disease (KD). However, ~20?% of KD patients have persistent fever or recurrence of fever after the initial IVIG treatment, which increases the risk for coronary artery lesions (CALs). Furthermore, the mechanism of IVIG resistance in KD patients still is unknown. The number of CC chemokine ligand 3-like 1 (CCL3L1) gene copies is reported to be associated with KD and IVIG resistance in Japanese patients. In addition, the authors observed significant upregulation of the CCL3L1 gene expression after in vitro immunoglobulin treatment in B cell lines derived from KD patients. Therefore, this study of 459?KD patients and 496 healthy control subjects tested whether the number of CCL3L1 gene copies is associated with a risk of KD, CALs, and/or IVIG resistance in Korean KD patients. However, the number of CCL3L1 gene copies was not associated with KD (P?=?0.18), CAL formation (P?=?0.062), or the IVIG resistance (P?=?0.90). Therefore, the results indicate that the number of CCL3L1 gene copies does not have a role in susceptibility to KD or CALs nor with IVIG resistance in Korean KD patients.     

Early treatment with intravenous immunoglobulin in patients with Kawasaki disease

OBJECTIVES: To determine if a shorter interval between Kawasaki disease (KD) treatment with intravenous immunoglobulin (IVIG) and fever onset results in increased treatment failures, need for adjunctive therapy, or development of coronary artery lesions. STUDY DESIGN: Patients with KD (n = 178; 89 matched pairs) diagnosed between 1987 and 1999 were included in this case-control study. All patients had fever plus at least 4 of the 5 clinical criteria for KD. Eighty-nine patients who received IVIG at day 5 or earlier were matched to patients diagnosed within 4 weeks and given IVIG at days 6 to 9 of fever. Compiled data from a detailed chart review included demographics, clinical features, fever duration, investigations, disease course, and response to therapy. Differences between matched case and control pairs were analyzed by means oft tests and McNemar tests. RESULTS: No demographic differences were noted between the two groups. Patients treated on day 5 or less of fever had a shorter total fever duration (5.2 +/- 1.9 days vs 8.0 +/- 1.8 days, P <.0001), longer fever after IVIG treatment (1.5 +/- 1.9 days vs 0.8 +/- 1.3 days, P =.008), and less coronary artery ectasia at 1 year after KD onset (4% vs 16%, P =.02). There was no significant difference between cases and control patients in the number of patients with KD recrudescence, need for repeat courses of IVIG, need for corticosteroids, length of hospitalization, or development of coronary artery aneurysms within the first 3 months. Patients who were treated on day 5 or less of fever had higher levels of serum albumin (36 +/- 5 g/L vs 33 +/- 5 g/L, P <.01) and serum ALT (115 +/- 155 U/L vs 46 +/- 49 U/L, P <.001) as well as a lower platelet count (354 +/- 131 vs 403 +/- 166, P =.02) than did control patients during the acute phase. CONCLUSIONS: Early treatment of KD resulted in less coronary ectasia at 1 year after KD onset but was not associated with a quicker resolution of fever, an increased number of treatment failures, an increased need for adjunctive therapy, length of hospitalization, nor development of coronary artery lesions. In children with fever and classic clinical and laboratory findings of KD, treatment with IVIG on or before 5 days of fever resulted in better coronary outcomes and decreased the total length of time of clinical symptoms.     

Alteration of biochemical profiles after high-dose intravenous immunoglobulin administration in Kawasaki disease

Intravenous immunoglobulin (IVIG) has been used as an immunomodulatory treatment for several immune-mediated diseases. Early effects of high-dose IVIG treatment on biochemical profiles including lipids and proteins were evaluated in patients with Kawasaki disease (KD). Twelve children with KD (9 boys) were treated with IVIG at 2 g/kg over a period of 12 h. Serial sera samples were collected from the patients four times: before IVIG treatment and 2 h, 24 h and 7 d after IVIG treatment. The samples were frozen at -20°C before biochemical analysis. A significant decrease in albumin concentration was found 2 h and 24 h after IVIG treatment, but this recovered to the pretreatment level after 7 d. Total cholesterol and triglyceride increased slightly after 7 d. A significant decrease in HDL-cholesterol and C-reactive protein was seen 2 h and 24 h after IVIG treatment.

Conclusion : High-dose IVIG affects immediate changes in protein profiles and HDL-cholesterol in KD. Changes in HDL-cholesterol induced by IVIG may be the result of changes in systemic protein metabolism.     

儿童川崎病并发冠状动脉损害的危险因素分析

目的 探讨儿童川崎病(KD)并发冠状动脉损害(CAL)的危险因素。方法 回顾性分析895例KD患儿的病历资料,将其分为并发CAL 组(n=284)和未并发CAL 的对照组(n=611),比较两组临床及实验室指标,并对KD 患儿并发CAL的危险因素进行多因素logistic 回归分析。结果 男性、发生CAL 以外并发症、不典型KD、静脉注射丙种球蛋白(IVIG)抵抗、IVIG 治疗前发热时间>5 d、血清降钙素原(PCT)增高为KD患儿并发CAL 的独立危险因素(OR 值分别为1.712、2.028、3.655、2.912、1.350、1.068,均POR=0.931,P结论 男性KD患儿、不典型KD 患儿以及发生CAL 以外并发症、发热时间较长、IVIG 治疗抵抗的KD患儿并发CAL 的风险较高。血清PCT与ALB预测KD患儿并发CAL的价值不大。
