PURPOSE: The relationship between the number and size of platelet in the thrombocytosis period of Kawasaki disease (KD) was analyzed to investigate the risk of thrombosis in KD. METHODS: The number and size of the platelet in patients with KD (n=221) were serially evaluated and the relationship was analyzed. RESULTS: The value of mean platelet volume (MPV) was inversely correlated with the highest number of platelet with r(2)=0.0741, P < 0.001. CONCLUSIONS: Considering the size of the platelet, the vulnerability of thrombosis during the thrombocytosis period of KD might be low.

PURPOSE: The aims of this study were to compare serum procalcitonin (PCT) levels between febrile children with Kawasaki disease (KD) and those with bacterial or viral infections, and assess the clinical usefulness of PCT level in predicting KD. METHODS: Serum PCT levels were examined in febrile pediatric patients admitted between August 2013 and August 2014. The patients were divided into 3 groups as follows: 49 with KD, 111 with viral infections, and 24 with bacterial infections. RESULTS: The mean PCT level in the KD group was significantly lower than that in the bacterial infection group (0.82±1.73 ng/mL vs. 3.11±6.10 ng/mL, P=0.002) and insignificantly different from that in the viral infection group (0.23±0.34 ng/mL,P=0.457). The mean erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level in the KD group were significantly higher than those in the viral and bacterial infection groups (P<0.001 and P<0.001 for ESR, P<0.001 and P=0.005 for CRP, respectively). The proportion of patients in the KD group with PCT levels of >1.0 ng/mL was significantly higher in the nonresponders to the initial intravenous immunoglobulin treatment than in the responders (36% vs. 8%, P=0.01). CONCLUSION: PCT levels may help to differentiate KD from bacterial infections. A combination of disease markers, including ESR, CRP, and PCT, may be useful for differentiating between KD and viral/bacterial infections.

A girl was diagnosed with intravenous immunoglobulin (IVIG)-resistant Kawasaki disease (KD) due to pyrexia and hemoptysis for eight days. The girl was a school-age child with major clinical manifestations of pyrexia, skin rash, enlargement of bilateral cervical lymph nodes, conjunctival hyperaemia, red and cracked lips and strawberry-like tongue, followed by swelling of both hands and feet. Laboratory examination showed significant increases in white blood cell count, platelet count, C-reactive protein, erythrocyte sedimentation rate and liver enzymes, a significant reduction in albumin, and the presence of aseptic pyuria. After the first course of IVIG treatment, the girl still had recurrent pyrexia, with hemoptysis on day 2 after admission, and lung CT showed uneven luminance and patchy shadow. The symptoms were quickly alleviated after the second course of IVIG treatment combined with methylprednisolone and aspirin treatment. KD is a febrile disease characterized by multiple systemic vasculitis in childhood and can involve various organ systems such as the heart, lungs, kidneys and the nervous system. Therefore, it is necessary to carefully monitor and recognize the rare symptoms of KD, and early recognition of pulmonary complications of KD can avoid delay in diagnosis, prevent the development of more serious complications, and help with early treatment and disease recovery.

5.Recent research on platelet-leukocyte aggregates and their role in the pathogenesis of Kawasaki disease.
Chinese Journal of Contemporary Pediatrics 2023;25(6):587-594
Activated platelets may interact with various types of leukocytes such as monocytes, neutrophils, dendritic cells, and lymphocytes, trigger intercellular signal transduction, and thus lead to thrombosis and synthesis of massive inflammatory mediators. Elevated levels of circulating platelet-leukocyte aggregates have been found in patients with thrombotic or inflammatory diseases. This article reviews the latest research on the formation, function, and detection methods of platelet-leukocyte aggregates and their role in the onset of Kawasaki disease, so as to provide new ideas for studying the pathogenesis of Kawasaki disease.

OBJECTIVETo explore the change in serum adiponectin levels and its significance in children with Kawasaki disease (KD).
METHODSForty-five KD patients were enrolled in this study, including 18 with coronary artery lesions (CAL group) and 27 without coronary artery lesions (NCAL group). Twenty healthy children were recruited to the control group. Enzyme-linked immunosorbent assay was used to measure serum adiponectin levels, and an automatic biochemical analyzer was used to measure the levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C).
RESULTSThe serum adiponectin levels in the CAL and NCAL groups were significantly lower than in the control group during the acute phase, subacute phase, and recovery phase (P<0.01), with lower levels observed during the acute phase and subacute phase (P<0.01). Compared with the NCAL group, the CAL group had significantly higher serum levels of adiponectin during the acute phase and recovery phase (P<0.05). The levels of TC, HDL, and LDL in the NCAL and CAL groups were significantly lower than in the control group (P<0.05). The levels of serum adiponectin in KD patients were positively correlated with the levels of TC, TG, and C-reactive protein and the occurrence of CAL (r=0.31, 0.30, 0.34, and 0.35, respectively; P<0.05).
CONCLUSIONSChildren with KD have metabolic disorders of blood lipids and reduced serum adiponectin levels. Reduced serum adiponectin levels may be the result of systemic inflammation, while increased adiponectin levels may be closely associated with the occurrence of CAL.

BACKGROUNDCardiac involvement is the most common complication of Kawasaki disease (KD); however, the underlying mechanisms are not understood. The present study was designed to investigate changes in plasma hydrogen sulfide (H(2)S) and nitric oxide (NO) levels in the acute and recovery stages of KD children and to examine their clinical significance.
METHODSThirty-five KD patients and 32 healthy children were enrolled in the study. KD patients were divided into two subgroups: a non-cardiac involvement group and a cardiac involvement group. Plasma H(2)S levels were measured using the sulfur-sensitive electrode method and plasma NO levels and NO synthase activity were determined using the nitrate reductase method both before and after intravenous immune globulin (IVIG) therapy.
RESULTSPlasma H(2)S levels significantly decreased in KD patients during the acute phase of the disease and NO levels were significantly increased, compared with the control group (P < 0.01). After treatment with IVIG, both plasma H(2)S and NO levels significantly increased (P < 0.01). The plasma levels of H(2)S were significantly lower in the cardiac involvement group compared with the non-cardiac involvement group (P < 0.05).
CONCLUSIONH(2)S and NO may play a role in the pathophysiological process of inflammation during the acute phase of KD. Endogenous H(2)S may exert protective effects with respect to cardiac complications in KD.

OBJECTIVES:
To investigate the clinical manifestations and laboratory examination results of children with Kawasaki disease complicated by macrophage activation syndrome (KD-MAS), and to provide a basis for identifying early warning indicators for the early diagnosis and treatment of KD-MAS.
METHODS:
A retrospective study was performed on 27 children with KD-MAS (KD-MAS group) and 110 children with KD (KD group) who were admitted to Wuhan Children's Hospital, Tongji Medical College, Huazhong University of Science and Technology, from January 2014 to January 2022. Clinical and laboratory data were compared between the two groups. The receiver operating characteristic (ROC) curve was used to investigate the value of laboratory markers with statistical significance in the diagnosis of KD-MAS.
RESULTS:
Compared with the KD group, the KD-MAS group had significantly higher incidence rates of hepatomegaly, splenomegaly, incomplete KD, no response to intravenous immunoglobulin, coronary artery damage, multiple organ damage, and KD recurrence, as well as a significantly longer length of hospital stay (P<0.05). Compared with the KD group, the KD-MAS group had significantly lower levels of white blood cell count, absolute neutrophil count, hemoglobin, platelet count (PLT), erythrocyte sedimentation rate, serum albumin, serum sodium, prealbumin, and fibrinogen (FIB), a significantly lower incidence rate of non-exudative conjunctiva, and significantly higher levels of C-reactive protein, alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase (LDH), and serum ferritin (SF) (P<0.05). The ROC curve analysis showed that SF, PLT, FIB, and LDH had high value in the diagnosis of KD-MAS, with areas under the curve (AUC) of 0.989, 0.966, 0.932, and 0.897, respectively (P<0.001), and optimal cut-off values of 349.95 μg/L, 159×109/L, 3.85 g/L, and 403.50 U/L, respectively. The combination of SF, PLT, FIB, and LDH had a larger AUC than PLT, FIB, and LDH alone in the diagnosis of KD-MAS (P<0.05), but there was no significant difference in the AUC between the combination of SF, PLT, FIB, and LDH and SF alone (P>0.05).
CONCLUSIONS
KD-MAS should be considered when children with KD have hepatosplenomegaly, no response to intravenous immunoglobulin, coronary artery damage, and KD recurrence during treatment. SF, PLT, FIB, and LDH are of high value in the diagnosis of KD-MAS, especially SF is of great significance in the diagnosis of KD-MAS.

OBJECTIVETo study serum levels of brain natriuretic peptide (BNP) in children with Kawasaki disease (KD) and the correlation between BNP levels and the heart function.
METHODSForty-three children with KD and thirty healthy children were enrolled. Serum levels of BNP were measured using ELISA. KD children received an echocardiographic examination, including measurements of left ventricular ejection fraction (LVEF), left ventricular shorten fraction (LVSF), cardiac index (CI) and left ventricular inflow velocity through the mitral annulus.
RESULTSMean serum level of BNP at the acute stage in children with KD was significantly higher than that at the recovery stage as well as the control group (p<0.01). The LVEF, LVSF and CI levels at the acute stage were significantly lower than those at the recovery stage in children with KD (p<0.05). The linear regression analysis showed that the BNP level was negatively correlated with the levels of LVEF, LVSF and CI (r=-0.63, -0.52, -0.53, p<0.05).
CONCLUSIONSThe serum BNP levels increase significantly in KD children at the acute stage, and are negatively correlated with the levels of LVEF, LVSF and CI. Measurement of serum BNP level is useful for the early diagnosis of KD.

OBJECTIVETo study the value of anti-neutrophil cytoplasmic antibody (ANCA) in diagnosis of Kawasaki disease (KD).
METHODSSerum ANCA was detected in 30 children with typical Kawasaki disease (TKD) and in 16 with incomplete Kawasaki disease (IKD) in the acute and the recovery phases respectively. Twenty-five healthy children were randomly selected as a control group. An ultrasonic cardiography (UCG) was performed on children with KD in the acute phase.
RESULTSThe mean positive rate of serum ANCA in the acute phase in KD children was 65%, with 69% in IKD children and 63% in TKD children, which were obviously higher than that in the control group (P<0.01). The positive rate of serum ANCA in the recovery phase in KD children was significantly lower than that in the acute phase (33% vs 65%, P<0.05). The positive rate of serum ANCA in the acute phase in children with KD was significantly higher than that detected by UCG (P<0.01). The incidence rate of coronary artery lesions in children with positive ANCA was obviously higher than that in children with negative ANCA (43% vs 13%; P<0.05).
CONCLUSIONSSerum ANCA may be used as a reference index for early diagnosis of KD and secondary coronary artery lesions in children.
