Indian Academy of Pediatrics Position Paper on Kawasaki Disease

Subsequent development of Kawasaki disease following acute human adenovirus infection among siblings

We report a middle-childhood girl presented with high-grade fever and headache for 4 days. Following this, the child developed mucocutaneous symptoms. She had a notable family history of autoimmune disease. Tests revealed increased inflammatory markers. On the sixth day of illness, a two-dimensonal echocardiogram showed an enlarged coronary artery, diagnosed as incomplete Kawasaki disease (KD) and treated with IVIG and aspirin.Within a week, her younger sibling, an early-childhood girl presented with features of viral prodrome, developed mucocutaneous lesions and subcutaneous oedema of limbs. Her investigations also showed elevated inflammatory markers and echocardiographic changes, diagnosed as incomplete KD.The subsequent development of KD in siblings, both showing initial viral symptoms and a family history of autoimmune disease, led to the suspicion of a potential viral trigger. This was confirmed through viral PCR studies for human adenovirus (type 3). These cases highlight an unusual occurrence of KD developing in siblings following acute adenoviral infection.

Institute of Child Health, Kolkata, 1956–2022

Institute of Child Health, Kolkata is an iconic pediatric institution of India, which had its inception as one of the first pediatric hospital of the country. Pediatrics, as a separate branch of medicine, different from the principles and practices of adult medicine, was conceptualized and materialized in India by the founder of this institution, who is referred to as one of the Father of Indian Pediatrics, Dr. Kshirode Chandra Chaudhuri. This article portrays the journey of ICH, the popular acronym of the famed Institute, through the last seven decades from 1956 till the present, trying to capture the initial years of its establishment in the late 1950s, followed by its gradual evolution to an institution of central importance in pediatric healthcare, medical education, research and development, and service to the society, particularly in Eastern India.

Unexpected late-onset aortic valvulitis and moderate regurgitation during longitudinal evaluation of atypical infantile Kawasaki disease: The heart beyond coronaries!

Kawasaki disease (KD) is the most common pediatric vasculitis with coronary involvement feared as the most serious complication. The reported case describes a child presenting initially with atypical KD and coronary artery aneurysms. He was treated with intravenous immunoglobulin and aspirin. In spite of adequate compliance and no clinical recurrence, serial echocardiography revealed nonregression of aneurysm and new-onset moderate aortic regurgitation (AR) in the subacute phase produced by prolapse of noncoronary cusp of the aortic valve. AR without aortic root dilatation from persistent inflammation of the valve leaflets in KD is a rare phenomenon. This case demonstrates unusual cardiac manifestations of KD and reoriented our protocol for long-term surveillance in infantile KD.

COVID-19 related multisystem inflammatory syndrome in children (MIS-C): a hospital-based prospective cohort study from Kerala, India

Objectives

To study (1) epidemiological factors, clinical profile and outcomes of COVID-19 related multisystem inflammatory syndrome in children (MIS-C), (2) clinical profile across age groups, (3) medium-term outcomes and (4) parameters associated with disease severity.

Design

Hospital-based prospective cohort study.

Setting

Two tertiary care centres in Kerala, India.

Participants

Diagnosed patients of MIS-C using the case definition of Centres for Disease Control and Prevention.

Statistical analysis

Pearson χ2 test or Fisher's exact test was used to compare the categorical variables and independent sample t-test or Mann-Whitney test was used to compare the continuous variables between the subgroups categorised by the requirement of mechanical ventilation. Bonferroni's correction was used for multiple comparisons.

Results

We report 41 patients with MIS-C, mean age was 6.2 (4.0) years, and 33 (80%) were previously healthy. Echocardiogram was abnormal in 23 (56%), and coronary abnormalities were noted in 15 (37%) patients. Immunomodulatory therapy was administered to 39 (95%), steroids and IVIg both were used in 35 (85%) and only steroids in 3 (7%) patients. Intensive care was required in 36 (88%), mechanical ventilation in 8 (20%), inotropic support in 21 (51%), and 2 (5%) patients died. Mechanical ventilation requirement in MIS-C was associated with hyperferritinaemia (p=0.001). Thirty-seven patients completed 3 months follow-up by April 2021, of whom 6 (16%) patients had some residual echocardiographic changes.

Conclusions

Patients with MIS-C in our cohort had varied clinical manifestations ranging from fever with mild gastrointestinal and mucocutaneous involvement to fatal multiorgan dysfunction. Immediate and medium-term outcomes remain largely excellent except for the echocardiographic sequelae in a few patients which are also showing a resolving trend. Hyperferritinaemia was associated with the requirement of mechanical ventilation.
