RationaleGreen inclusions (GI) are distinct morphological features found in phagocytic cells like neutrophils and monocytes. These intracellular structures exhibit bright green color with unclear boundaries, and their origin and clinical significance are still not fully understood. GI carriers, often middle-aged to elderly with liver dysfunction, face higher mortality rates, earning them the nickname "inclusions of death." This report presents a rare GI-related pediatric case, demonstrating a favorable response to blood purification therapy.Patient ConcernsA 10-year-old girl was admitted with recurrent fever, abdominal pain, and neurological symptoms, culminating in a transient cardiac arrest. Blood tests revealed multi-organ injury and a high risk of disseminated intravascular coagulation, while peripheral blood smear detected GI within neutrophil cytoplasm.DiagnosisThe patient was diagnosed with acute necrotizing encephalopathy, severe sepsis, and multiple organ failure.Interventions And OutcomesAfter receiving multiple sessions of blood purification therapy, peripheral blood GI levels markedly decreased, accompanied by improvements in various laboratory parameters and signs of neurological recovery. Unfortunately, due to financial constraints, the family opted to transfer the patient back to their local hospital, where she succumbed shortly after discharge.LessonsThis case underscores the complexities in managing GI-related pediatric cases. Moreover, it emphasizes the potential benefits of blood purification therapy in such scenarios. Notably, this study highlights a potential correlation between the level of GI in peripheral blood and disease severity, particularly in pediatric cases. While these findings hold clinical significance for the treatment and management of GI-related patients, further research focusing on middle-aged and elderly individuals is imperative to elucidate the fundamental relationship between peripheral blood GI quantity and clinical presentation and to evaluate the efficacy of blood purification in GI-related cases.Copyright © 2024 the Author(s).
