Neutropenic enterocolitis in patients with FLT3 mutated acute myeloid leukemia undergoing induction chemotherapy with midostaurin.

Int J Hematol 2018 Dec 3. Epub 2018 Dec 3.

Department of Hematology and Oncology, Marshall University, 1400 Hal Greer Blvd, Huntington, WV, 25701, USA.

Neutropenic enterocolitis mostly affects patients with acute myeloid leukemia (AML) who get treated with intensive chemotherapy which is associated with prolonged neutropenia; its pathogenesis is not well understood and the main factors in this life-threatening condition appear to be neutropenia, mucosal injury and a weakened immune system as a consequence of intensive chemotherapeutic agents. Midostaurin in combination with chemotherapy became the standard of care for FLT3 mutant AML since its approval by the United States Food and Drug Administration (FDA) in April 2017. Anecdotally in our institution, we noticed the common occurrence of neutropenic colitis in three out of three patients who were treated with midostaurin as part of induction chemotherapy for AML.

Use of Translational PK/PD Infection Models to Understand Impact of Neutropenia on Efficacy of Tedizolid Phosphate.

Antimicrob Agents Chemother 2018 Oct 29. Epub 2018 Oct 29.

Merck & Co. Inc., Kenilworth, NJ, USA

Tedizolid phosphate, the prodrug of the active antibiotic tedizolid, is an oxazolidinone for the treatment of acute bacterial skin and skin structure infections. Studies in a mouse thigh infection model demonstrated improved potency and pharmacokinetics-pharmacodynamics (PK/PD) vs linezolid. Subsequent studies showed that the efficacy of tedizolid was enhanced in immune competent (IC) compared with neutropenic (IS) mice, with stasis at clinically relevant doses being achieved only in the presence of granulocytes.

Ameliorative effect of silymarin against linezolid-induced hepatotoxicity in methicillin-resistant Staphylococcus aureus (MRSA) infected Wistar rats.

Biomed Pharmacother 2018 Dec 4;108:1303-1312. Epub 2018 Oct 4.

Department of Pharmacology, Nandha College of Pharmacy and Research Institute, Erode 638052, Tamilnadu, India.

Linezolid has a better choice for eradication of methicillin-resistant Staphylococcus aureus (MRSA) infections, but its use is limited because of linezolid-induced hepatotoxicity, myelosuppression, and lactic acidosis. This research elucidated the role of silymarin against hepatoxicity of linezolid therapy in MRSA infected Wistar rats. The rats were rendered neutropenic by an intraperitoneal injection of cyclophosphamide injection. Read More

[Efficacy and safety of decitabine in combination with G-CSF, low-dose cytarabine and aclarubicin in MDS-EB and AML-MRC].

Zhonghua Xue Ye Xue Za Zhi 2018 Sep;39(9):734-738

Institute of Hematology, Peking University People's Hospital, Beijing 100044, China.

To evaluate the clinical efficacy and safety of decitabine in combination with lower-dose CAG regimen (G-CSF, cytarabine and aclarubicin; D-CAG regimen) in the treatment of myelodysplastic syndromes with excess blasts (MDS-EB) and acute myeloid leukemia with myelodysplasia-related changes (AML-MRC), compared to standard CAG regimen. A total of 42 patients with newly diagnosed MDS-EB and AML-MRC from May 2011 to March 2017 were included in the retrospective study. 21 cases were initially treated with G-CSF for priming, in combination with cytarabine of 10 mg/m(2) q12h for 14 days and aclarubicin of 20 mg/d for 4 days (CAG regimen) and the other 21 cases were initially treated with decitabine of 20 mg/m(2) for 5 days and lower-dose CAG regimen (cytarabine of 10 mg/m(2) q12h for 7 days, aclarubicin of 10 mg/d for 4 days, and G-CSF for priming (D-CAG regimen).
