Insights
Multisystem Inflammatory Syndrome in Children (MIS-C) following COVID-19 infection presents with diverse symptoms. While both IVIG and combination therapy improved outcomes, combination therapy showed a trend toward better results in pediatric intensive care unit patients.
Area of Science:
- Pediatric critical care medicine
- Infectious diseases
- Rheumatology
Background:
- Children infected with SARS-CoV-2 can develop Multisystem Inflammatory Syndrome in Children (MIS-C).
- MIS-C presents with varied clinical features, affecting multiple organ systems.
- Gastrointestinal and ophthalmological symptoms are common in MIS-C.
Purpose of the Study:
- To describe clinical manifestations of MIS-C in children admitted to the pediatric intensive care unit (PICU).
- To evaluate the impact of different treatment strategies on patient outcomes.
Main Methods:
- Retrospective cross-sectional study of 11 MIS-C patients.
- Patients were classified using World Health Organization (WHO) criteria.
- Treatment involved intravenous immunoglobulin (IVIG) with or without corticosteroids.
Main Results:
- The study included 6 females and 5 males, with an average age of 5.08 years.
- Ten patients had confirmed SARS-CoV-2 infection; one had contact history.
- All patients exhibited fever and elevated inflammatory markers; clinical and inflammatory markers improved significantly post-treatment.
Conclusions:
- Both IVIG and combination therapy (IVIG plus corticosteroids) led to significant clinical improvement.
- Combination therapy suggested improved outcomes, though not statistically significant compared to IVIG alone.
Background:
Post coronavirus disease 2019 (COVID-19) infections, children presented with varying clinical manifestations of a Multisystem Inflammatory Syndrome in Children (MIS-C). The aim of our study is to identify the clinical manifestations upon admission to paediatric intensive care unit (PICU) and to identify how different treatments affected post-treatment outcomes. Methods: A retrospective cross-sectional study included 11 patients diagnosed with multisystem inflammatory syndrome based on the World Health Organization (WHO) classification and treated by intravenous immunoglobulin (IVIG) with/without corticosteroids. Results: There were six female and five male patients with an average age of 5.08±4.7 years. Ten had a confirmed positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) serological antibody test or polymerase chain reaction (PCR) test, with one having only contact history. The most common systems affected by MIS-C were gastrointestinal and ophthalmological presentations. All presented with fever and raised inflammatory markers (erythrocyte sedimentation rate, C-reactive protein, procalcitonin, ferritin, d-dimer, and lactate dehydrogenase). There was no statistical difference between both treatment groups. Clinical and inflammatory markers significantly improved in both groups.
Conclusion:
This study highlights an improved outcome associated with combination therapy, although there is no statistical significance between both groups.

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
