ABSTRACT
Multisystem Inflammatory Syndrome in children related to COVID-19 (MIS-C) is a new condition the aftermath of which is yet to be studied both in Bulgaria and globally. We present a 15 years old patient with MIS-C, diagnosed with acute abdomen, operated and consequently treated for septic shock syndrome, with late diagnosis and favorable outcome with standard treatment at a Pediatric Intensive Care unit. Early detection and timely diagnosis by testing for early inflammatory markers such as procalcitonin, serological testing of IgM and IgG antibodies for SARS-CoV-2 and multidisciplinary collaboration can significantly alter the complications of this serious condition. Clinical experience and standard therapeutic strategies will decrease the mortality, the need of intensive care as well as prevent the long-term consequences in the affected patients. © 2021 Academy of Medicine.
