ABSTRACT A previously healthy 11-month-old girl presented with fever and rash for 6 days. Physical examination revealed an irritable infant with a high fever, injected conjunctivae, red cracked lips, posterior auricular lymphadenopathy, hepatomegaly, generalized erythematous maculopapular rash and petechial hemorrhage on trunk, face and extremities. Complete blood count showed atypical lymphocytosis and thrombocytopenia. Dengue infection was initially diagnosed. The persistent fever and clinical manifestations of Kawasaki disease (KD) were observed on day 8 with high erythrocyte sedimentation rate (56 mm/hr). Treatment of KD included intravenous immunoglobulin on day 9 of the illness. Desquamation of the fingers was found on day 15 of the illness. Ectasia of left coronary artery with small aneurysmal dilatation was detected by echocardiography on day 15 of the illness. Hemagglutination-inhibition test and enzyme-linked immunosorbent assay for dengue virus eventually showed a four-fold rising. According to the literature review, this is the second reported case of dengue infection concomitant with KD. The natural course of each disease may be modified and causes some difficulties in diagnosis and management.

    ABSTRACT: In recent years, many investigators have focused on potential associations between infections and vascular inflammation. We review the principal pathogenic mechanisms that have been implicated for possible roles in the vascular inflammation initiated by infectious agents. We also summarize the most important literature related to this topic. A novel theory known as autoantigen complementarity suggests that an infectious agent could trigger antineutrophil cytoplasmic antibody-associated vasculitis. Several recent studies investigating the presence of parvovirus B19 and herpesviruses in temporal arteries with giant cell arteritis have yielded contradictory results. A recent study has identified higher frequency of a novel human virus, the 'New Haven coronavirus', in respiratory secretions of children with Kawasaki disease. Many case reports have suggested potential relationships between human pathogens and vasculitis. There remains considerable interest in the possibilities of primary vasculitic syndromes caused in some fashion by infection. With the exception of a few well sustained associations - for example hepatitis B or C with known vasculitic syndromes - most of the purported links between microbial agents and primary vasculitides remain speculative.

    ABSTRACT: Kawasaki disease is an acute, self-limited vasculitis of childhood. The increasing frequency of the disease as well as the deficiency of specific diagnostic means renders its diagnosis and treatment an area of intense investigation. The purpose of this review is to summarize all the known features of Kawasaki disease and also give an insight to the latest findings. Kawasaki disease is one of the leading causes of acquired heart disease in children while its cause remains essentially unknown. Viruses, bacterial conventional as well as superantigens, and genetic polymorphisms have been implicated in the etiology of the disease. Markers of inflammation, such as CCL2 and CCXCL10, contribute to the pathology and the diagnosis of Kawasaki disease. Intravenous administration of immunoglobulin remains the mainstay of therapy for Kawasaki disease. Nevertheless, forms of the disease refractory to intravenous administration of immunoglobulin therapy may respond to aspirin, corticosteroids, cyclophosphamide, and/or plasmapheresis. The present review covers evidence regarding the history of Kawasaki disease, the epidemiology, etiology, pathology, genetic influences, and long-term sequela. It also includes an evaluation of contemporary diagnostic techniques and optimal therapeutic approaches with an emphasis on recent publications.

    ABSTRACT: There are several pediatric conditions which can present with fever and rash; however, it is uncommon to have two diseases occurring in a patient at the same time. We report a young child with fever and rash. He was initially diagnosed to have dengue fever based on clinical features and serological tests. Later in the course of illness he developed findings consistent with Kawasaki disease. This is extremely unusual and has rarely been reported before.
