GATA2 deficiency is a genetic disorder caused by inherited or sporadic haploinsufficient mutations in the GATA2 gene. Patients have abnormalities in hematopoiesis, lymphangiogenesis and immunity; encompassing a broad range of clinical syndromes, mainly characterized by monocytopenia, B and NK cell cytopenia, severe or recurrent infections, and a high risk of developing myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). We report a case of an Argentinean woman who presented with multiple opportunistic infections as her first manifestation of GATA2 deficiency.

Sepsis is a life-threatening condition resulting from pathogen infection and characterized by organ dysfunction. Programmed cell death (PCD) during sepsis has been associated with the development of multiple organ dysfunction syndrome (MODS), impacting various physiological systems including respiratory, cardiovascular, renal, neurological, hematological, hepatic, and intestinal systems. It is well-established that pathogen infections lead to immune dysregulation, which subsequently contributes to MODS in sepsis.
