Background: Multisystem inflammatory syndrome in neonates (MIS-N) is a rare condition thought to be associated with prenatal exposure to maternal severe acute respiratory syndrome coronavirus 2 infection. This immune-mediated hyperinflammation has been described in neonates with multiorgan dysfunction, including cardiopulmonary, encephalopathy, coagulopathy, and vascular complications. However, renovascular complications in MIS-N are rare.

Dengue infection is emerging as one of the most common tropical diseases globally. It manifests in varying severity from asymptomatic to the most severe forms of the disease, characterized by coagulopathy, increased vascular fragility, and permeability (dengue haemorrhagic fever) that may progress to hypovolaemic shock (dengue shock syndrome). For atypical manifestations, a new terminology known as expanded dengue syndrome (EDS) was introduced.

Purposeof The Review: In this review article, we aim to provide an overview of the pathophysiology, the clinical features, the therapeutic management and prognosis of patients affected by Multisystemic inflammatory syndrome (MIS) with cardiac involvement, focusing on myocarditis and pericarditis.
Recent Findings: MIS is a multiorgan hyperinflammatory condition due to a cytokine storm following (within 4-12 weeks) SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) infection. First described in children, it also affects young adults without comorbidities, predominantly males with highly heterogeneous clinical manifestations, including cardiac involvement.

The complex link between COVID-19 and immunometabolic diseases demonstrates the important interaction between metabolic dysfunction and immunological response during viral infections. Severe COVID-19, defined by a hyperinflammatory state, is greatly impacted by underlying chronic illnesses aggravating the cytokine storm caused by increased levels of Pro-inflammatory cytokines. Metabolic reprogramming, including increased glycolysis and altered mitochondrial function, promotes viral replication and stimulates inflammatory cytokine production, contributing to illness severity.

Adult-onset hemophagocytic lymphohistiocytosis (HLH) is a life-threatening hyperinflammatory syndrome characterized by dysregulated immune activation. Diagnosing HLH poses significant challenges due to its nonspecific clinical presentation, which often mimics infections, malignancies, and autoimmune diseases. Early recognition and prompt initiation of immunosuppressive therapy are crucial, as delayed treatment is associated with a high risk of mortality.
