Kawasaki disease: infection, immunity and genetics.

Kawasaki disease is an acute multisystem vasculitic syndrome of unknown etiology occurring mostly in infants and children younger than 5 years of age. In developed countries, Kawasaki disease is currently the leading cause of acquired heart diseases in children. However, it is still a mysterious disease.

Methylprednisolone pulse therapy for massive lymphadenopathy in a child with intravenous immunoglobulin-resistant Kawasaki disease.

Kawasaki disease (KD) is an acute febrile multi-system vasculitis of unknown etiology. The diagnosis is based on clinical features. We describe a case of intravenous immunoglobulins (IVIG)-resistant KD presenting with persistent fever and massive cervical lymphadenopathy associated with mild respiratory distress.

Obstruction of the aorta and left pulmonary artery after Gianturco coil occlusion of patent ductus arteriosus.

We report an unusual case of simultaneous obstruction of the left pulmonary artery and descending thoracic aorta after Gianturco coil occlusion in a 15-month-old boy. The diagnosis was made by echocardiography and cardiac angiography. At surgery, thrombi coating on the protruded parts of the Gianturco coil in the pulmonary artery and aorta were found.

Enhancement of CREBSerine-133 phosphorylation through nitric oxide-mediated signaling induced by bacterial lipopolysaccharide in vascular smooth muscle cells from rats.

Nitric oxide (NO) induced by bacterial lipopolysaccharide (LPS) plays a critical role in various patho-physiological implications, such as atherosclerosis, vasculitis and septic shock. In addition, cAMP-responsive element binding protein (CREB), an important transcription factor for cell differentiation, has been shown to be involved in atherosclerogenesis in VSMCs. Here we investigated the possibility whether LPS-induced NO signaling led to phosphorylation of cAMP-responsive element binding protein on Serine-133 (CREBSer-133) in cultured vascular smooth muscle cells (VSMCs) from rats.

Expression of CD40 ligand on CD4+ T-cells and platelets correlated to the coronary artery lesion and disease progress in Kawasaki disease.

Objective: Kawasaki disease (KD) is an acute febrile vasculitic syndrome in children. CD40 ligand (CD40L) has been implicated in certain types of vasculitis. We proposed that CD40L expression might be correlated with coronary artery lesions in KD.

Aortico-left ventricular tunnel associated with single coronary artery in an infant.

Aortico-left ventricular tunnel (ALVT) is a rare congenital malformation in which an abnormal communication between the aorta and the left ventricle (LV) bypasses the aortic valve. In infants, it usually presents with congestive heart failure. The clinical presentations mimic aortic regurgitation or ruptured sinus of Valsalva aneurysm into the LV.

Decreased nitric oxide production after intravenous immunoglobulin treatment in patients with Kawasaki disease.

Objective: To assess nitric oxide (NO) production and different displays of NO synthase (NOS) isoforms in patients with Kawasaki disease (KD) before and after intravenous immunoglobulin (IVIG) treatment.

Study Design: Blood and urine samples were collected from patients with KD before IVIG treatment and 3 days afterward. Age-matched febrile patients with various diseases served as control patients.
