Kawasaki disease (KD) is an acute systemic vasculitis of childhood. The diagnosis can be made in a patient who presents with a prolonged high fever and meeting at least four of five criteria including polymorphous rash, mucosal changes, extremity changes (including swelling and/or palmar and plantar erythema), bilateral nonsuppurative conjunctivitis, and unilateral cervical lymphadenopathy. Atypical KD refers to patients who have not met the full criteria and in whom atypical features may be present. We discuss a case of a 6-year-old male who presented to the Emergency Department with torticollis...

Maternal Graves' disease (GD) during pregnancy may influence thyroid function in fetuses. Neonates born to mothers with high serum TSH receptor antibody (TRAb) levels have been reported to develop 'neonatal GD'. Therefore, evaluations of serum thyroid hormone and TRAb levels in neonates upon birth are crucial for a prompt diagnosis. At delivery, we measured TRAb with third-generation TRAb test using an M22 human monoclonal antibody in neonates by collecting umbilical cord blood in a blood collection tube with lithium-heparin, which provides a whole blood/plasma sample...

In colorectal cancer, gain-of-function mutations in KRas play a critical role in malignant transformation. Tumor growth in colorectal cancer is known to be promoted by the intestinal myofibroblasts (IMFs) that localize adjacent to the cancer cells, but the mechanisms of interaction between KRas-mutated cancer cells and the myofibroblasts remain unclear. Here, we investigated the effects of KRas-mutated cells on the behavior of myofibroblasts by using mouse primary IMFs and cells of an IMF cell line (LmcMF) and a mouse colon epithelial cell line (aMoC1)...

Management guidelines for refractory Kawasaki disease (KD) are vague. We sought to assess practice variation and identify factors associated with large/complex coronary artery aneurysms (LCAA) and resource utilization in refractory KD. This retrospective cohort study identified patients aged ≤18 years with KD (2004 to 2014) using the Pediatric Health Information System. Refractory KD was defined as receiving >1 dose of intravenous immunoglobulin. Demographics, medications, concomitant infections, length of stay (LOS), and charges were collected...

INTRODUCTION: Early diagnosis and treatment of Kawasaki disease as the most common cause of acquired heart disease in childhood, may significantly improve the prognosis. Diagnosing infantile Kawasaki (younger than a year) is difficult because of obscure symptoms; at the same time they are at the higher risk of coronary abnormalities. CASE PRESENTATION: We report three infants with prolonged (more than 5 days) fever and peripheral gangrene without any other clinical manifestations of Kawasaki disease...

Coronary artery aneurysms (CAA) may occur in Kawasaki disease (KD). Patients with giant CAA (diameter >8 mm), in particular, have higher risk of myocardial infarction. Previous reports have demonstrated the necessity of anticoagulation therapy in such cases. The management of patients with KD complicated by giant CAA later in life, however, remains controversial. Here, we describe the strict management in the case of a 28-year-old pregnant Japanese woman with KD with giant CAA (diameter, 11 mm). Instead of warfarin, the patient was given low-dose aspirin and i...

BACKGROUND: Dalteparin, a low-molecular-weight heparin, has anticoagulant and anti-angiogenic activity. This study investigated whether dalteparin reduced coronary artery lesion (CAL) prevalence, and resistance to intravenous immunoglobulin (IVIG) therapy in Kawasaki disease (KD). METHODS: This retrospective study comprised two parts. In the first cohort, 126 patients with KD (68 male, 58 female; median age: 22 months, range: 1-67 months) admitted to Nihon University Nerima-Hikarigaoka Hospital from January 2004 to June 2008, received either dalteparin 75 IU/kg/day, IVIG 400 mg/kg/day for 5 consecutive days, and aspirin 30 mg/kg/day, or dalteparin 75 IU/kg/day and aspirin 30 mg/kg/day, until clinical improvement...

Heparin is a sulfated glycosaminoglycan (GAG), which contains N-acetylated or N-sulfated glucosamine (GlcN). Heparin, which is generally obtained from the healthy porcine intestines, is widely used as an anticoagulant during dialysis and treatments of thrombosis such as disseminated intravascular coagulation. Dermatan sulfate (DS) and chondroitin sulfate (CS), which are galactosamine (GalN)-containing GAGs, are major process-related impurities of heparin products. The varying DS and CS contents between heparin products can be responsible for the different anticoagulant activities of heparin...

The oral direct factor Xa inhibitor darexaban administered intraduodenally prevented venous thrombus formation in both rats and rabbits with no effect on bleeding. The indirect parenteral Factor Xa inhibitor fondaparinux exerted similar properties, only prolonging bleeding time at extremely high doses. In contrast, the thrombin inhibitor ximelagatran and low-molecular-weight heparin enoxaparin prolonged bleeding time at antithrombotic doses. Studies using human platelets showed darexaban glucuronide, a darexaban metabolite that predominantly determines darexaban antithrombotic effects in vivo, had no effect on platelet activation and aggregation, while heparin and enoxaparin activated platelets...

A conjugate of polyL-lysine (PLL) with unsulfated dextran produced by reductive amination was found to have remarkable anti-HIV-1 activity against both the macrophage-tropic R5 virus Ba-L and T-cell line tropic X4 virus IIIB strains, although neither PLL nor dextran has such activity. The conjugate is a pseudoproteoglycan (pseudoPG) that simulates the structure of a proteoglycan. Conjugation with dextran was found to produce an antiviral effect in three kinds of assay systems including a human CD4(+) T-cell line, and the pseudoPG synthesized using 10 kDa PLL and 10 kDa dextran showed EC(50) 4-40 times lower than that of sulfated dextran or heparin against Ba-L and EC(50) equal to that against IIIB, indicating that PLL-dextran (PLL-Dex) was more effective against R5 virus than sulfated polysaccharides...

N-acetyl-seryl-aspartyl-lysyl-proline (AcSDKP) is a natural inhibitor of pluripotent hematopoietic stem cell proliferation and is normally found in human plasma. Because AcSDKP is hydrolyzed by the N-terminal active site of angiotensin converting enzyme and partially eliminated in urine, its plasma level is a result of a complex balance between its production, hydrolysis by ACE, and renal elimination. In this study, we attempted to establish an enzyme immunoassay (EIA) for quantifying AcSDKP-like immunoreactive substance (IS), which is applicable for monitoring plasma AcSDKP levels in healthy subjects and patients with chronic renal failure...

Anticoagulation for thromboembolic disease and bleeding, the main complication of anticoagulation therapy, are uncommon but are potentially life- or limb-threatening conditions that may present in the pediatric emergency department. Thromboembolic disease in children usually occurs as a complication of vascular access, primarily in children with congenital heart disease or cancer. However, complications of anticoagulation therapy used in the treatment of venous thromboembolism, pulmonary embolism, and blocked central venous catheter; arterial thromboembolism, including arterial ischemic stroke, Kawasaki disease, and after cardiac surgery, may warrant a visit to n the pediatric emergency department...

Heparin sodium and heparin calcium, which are widely used as anti-coagulants, are known to potentially contain the natural impurity dermatan sulfate (DS). Recently serious adverse events occurred in patients receiving heparin sodium in the US, and a contaminant oversulfated chondroitin sulfate (OSCS) was found to be a cause of the events. To ensure the quality and safety of pharmaceutical heparins, there is need of a physicochemical identification test that can discriminate heparin from the heparin-related substances as well as a sensitive purity test for OSCS...

Patients with severe coronary artery involvement after Kawasaki disease (KD) require long-term systemic anticoagulation. We sought to compare our experience with thrombotic coronary artery occlusions, safety profile, and degree of coronary artery aneurysm regression in KD patients treated with low molecular weight heparin (LMWH) versus warfarin. Medical records of all KD patients diagnosed between January 1990 and April 2007 were reviewed. Of 1374 KD patients, 38 (3%) received systemic anticoagulation, 25 patients received LMWH from diagnosis onward, 12 of whom were subsequently switched to warfarin, and 13 received warfarin from onset...

We report a 15-month old girl with acute myocardial infarction 3 months after treatment for Kawasaki disease (KD); she had no coronary aneurysms. In the first 2 months after KD, she had normal electrocardiograms (ECGs) and echocardiograms that showed mildly dilated coronary arteries. At 3 months, she was asymptomatic but developed ECG changes of anteroseptal MI and increased troponin levels. Echocardiogram showed regional wall-motion abnormalities and decreased left ventricular function. She was admitted and treated with heparin and nitroglycerin drips...
