Patients with GATA2 (Emberger syndrome) deficiency needs early hematopoietic stem cell transplant (HSCT) before evolving in to myelodysplastic syndrome or acute myeloid leukemia and with time given compromised organ dysfunction leads to increase regimen-related toxicities. Most published cases have used nonmyeloablative conditioning regimens, show higher incidences of rejection and relapse rates and umbilical cord blood transplant has been reported to be suboptimal in patients with GATA2 deficiency because of longer period of engraftment leads to more infections and mortality. We report a 4.5-year-old girl with GATA2 deficiency who underwent matched unrelated donor HSCT utilizing a myeloablative conditioning regimen including intravenous busulfan (total dose of 12.8 mg/kg) and fludarabine (total dose of 160 mg/m) She tolerated the conditioning regimen and bone marrow infusion well. Her initial chimerism was mixed (90% donor), cyclosporine was gradually weaned and discontinued at day+85 and this resulted in conversion to full-donor chimerism. Bone marrow assessment 3 months post-HSCT revealed normal hematopoiesis and absence of monosomy 7. At 20 months of follow-up she had full-donor chimerism with complete reconstitution of the all hematopoietic stem cells. Myeloablative matched unrelated donor HSCT represents an effective option for cure in patients with GATA2 deficiency and Emberger syndrome.

The vascular endothelium is vital for cardio-pulmonary homeostasis and, thus, plays a crucial role in preventing life-threatening lung diseases. The transcription factor GATA2 is essential for hematopoiesis and maintaining vascular integrity. Heterozygous mutations in GATA2 can lead to a primary immunodeficiency syndrome with pulmonary manifestations.

Background: Germline GATA2-deficiency usually manifests as immunodeficiencies and myeloid neoplasms and sometimes with dermatological diseases, including warts, panniculitis, and skin cancers.
Case: We report a 36-year-old woman with germline GATA2-deficiency who developed Merkel cell carcinoma followed by acute myeloid leukemia. Molecular analysis revealed a germline GATA2 S447R variant, not reported from the previous reported case, suggesting a potential association with Merkel cell carcinoma.

Aim: Hypertensive nephropathy is a common complication of hypertension. However, no effective measures are currently available to prevent the progression of renal insufficiency. Gasdermin D (GSDMD) is a crucial mediator of pyroptosis that induces an excessive inflammatory response.
