Neutropenia-acquired
The most common cause of acquired neutropenia is infection. HBV, EBV, and HIV.
The second most common is medica-tion exposure: beta-lactam antibiotics, anti-thyroid drug, anti-tuberculosis, ticlopidine, baktar, carbamazepine, captopril, digitals, indomethacin

Kostmann syndrome Severe congenital neutropenia Cyclic neutropenia Ela2 gene HAX1 is a ubiquitously expressed mitochondrial
protein with weak homology to bcl-2 Wiskott-Aldrich syndrome protein (WASp) Gfi-1 zinc-finger protein, transcriptional repressor

5-Azacytidine was approved for the treatment of MDS in 2004
Azacytidine prolonged survival, delayed progression to AML, and improved quality of life. Complete response (CR) rate 7%, 16%PRs and 37% hematologic improvement also seen.
Decitabine was also evaluated in a phase 3 trial, and a 35% overall response rate was seen (9% CR, 8% PR, 18% hematologic improvement).

Genetic alterations affecting clinical outcome of cytogenetically normal acute myeloid leukemia (AML) patientsGenetic Alteration Prognostic SignificanceFavorableNPM1 mutations Patients with NPM1 mutations who do not harbor FLT3-ITD have significantly
better CR rates, EFS, RFS, DFS, and OS than patients without NPM1 mutations and FLT3-ITD.NPM1 mutations do not have a significant effect on prognosis of patients with FLT3-ITD.
CEBPA mutations Patients with CEBPA mutations have CRD and OS significantly longer than patients with the wild-type CEBPA gene.
Unfavorable
FLT3-ITD Patients with FLT3-ITD have significantly shorter CRD, DFS and OS than patients who do not harborFLT3-ITD.Particularly poor prognosis is conferred by FLT3-ITD coupled with no expression of a FLT3 wild-type allele or a high FLT3 mutant to FLT3 wild-type allele ratio.
MLL-PTD Patients with MLL-PTD have remission duration significantly shorter than patients without MLL-PTD.
