AI Article Synopsis
- The study examined how serum procalcitonin (PCT) levels can predict outcomes in acute leukemia patients with bacterial bloodstream infections by analyzing data from 236 patients over three years.
- Results showed a clear correlation between higher PCT levels and increased rates of infection-related death and complications like septic shock, with statistical significance across different concentration groups.
- The findings suggest that higher procalcitonin levels are an independent risk factor for severe outcomes, indicating its potential as a key prognostic marker in this patient population.
Article Abstract
Objective: To investigate the effects of serum procalcitonin(PCT) levels for predicting the outcome of bacteria bloodstream infection in acute leukemia patients.
Methods: Clinical data from 236 patients with acute leukemia accompanied by bacterial bloodstream infection during July 2014 to November 2017 were retrospectively analyzed, 236 patients were divided into 5 groups (<0.05 ng/ml, 0.05- <0.5 ng/ml, 0.5- <2.0 ng/ml, 2.0- <10.0 ng/ml and >10.0 ng/ml) according to PCT concentrations.
Results: The median age of patients was 40(13-73) years old. The male 123 cases(52.1%) and female 113 cases(47.9%) in 236 patients. The incidence of infection-related dealth in 5 groups was 0%, 1.4%, 13.8%, 25.0% and 33.3%, respectively; the incidence of septic shock and other serious complications in 5 groups was 0%, 2.1%, 13.8%, 25.0%, 33.3% and 6.4%, 7.0%, 24.1%, 41.7%, 50.0%, respectively, showing the concentration dependent manner and statistically significant difference (u=2127, P=0.000; u=2234, P=0.000; u=4102, P=0.000). Further analysis showed that with the increase of PCT concentration, the cumulative incidence of septic shock, infection-related death and other serious complications was gradually increased with statistically significance (HR=2.887, P=0.000, 95%CI:1.960-4.260; HR=3.158, P=0.000, 95%CI: 2.100-4.740; HR=2.158, P=0.000, 95%CI:1.550-3.000) respectively. Increased procalcitonin level is an independent risk factor for septic shock and infection-related death (HR=2.517, P=0.000, 95%CI: 1.520-4.168; HR=2.881, P=0.000, 95%CI: 1.692-4.904)respectively.
Conclusion: Serum procalcitonin level positively correlates with the incidence of serious bacteria bloodstream infection complications in the patients with acute leukemia. Increased procalcitonin level is an independent risk factor for septic shock and infection-related death, indicating that procalcitonin may be an important prognostic factor for infection outcome in acute leukemia patients with bacteremia.

Targeting the WDR5-MLL1 protein-protein interaction (PPI) is considered to be an effective approach for the treatment of MLL-rearranged leukemia. However, interfering with WDR5-MLL1 PPI reduces methylated H3K4 levels and induces a decline in acetylated H3 levels, which may contribute to the suboptimal cellular efficacy of WDR5 inhibitors. We observed that cotreatment with WDR5-MLL1 PPI and HDAC inhibitors augmented the antiproliferative effect in MV-4-11 cells.

To investigate the role of ALKBH3 in acute myeloid leukemia (AML), we constructed an animal model of xenotransplantation of AML. Our study demonstrated that ALKBH3-mediated m1A demethylation inhibits ferroptosis in KG-1 cells by increasing ATF4 expression, thus promoting the development of AML. These findings suggest that reducing ALKBH3 expression may be a potential strategy to mitigate AML progression.

Objective: To retrospectively analyze the incidence of infections in elderly acute myeloid leukemia (AML) patients undergoing induction therapy with venetoclax combined with hypomethylating agents and to compare these findings with those from patients receiving standard or low-dose chemotherapy.
Methods: Medical records of 169 elderly (≥60 years old) AML patients diagnosed via MICM (morphology, immunology, cytogenetics, and molecular genetics) at the First Affiliated Hospital of USTC between June 2019 and June 2022 were reviewed. Patients were divided into three groups: venetoclax combined with hypomethylating agents group (targeted therapy group), standard chemotherapy group, and low-dose chemotherapy group.
G-quadruplexes (G4s) are four-stranded alternative secondary structures formed by guanine-rich nucleic acids and are prevalent across the human genome. G4s are enzymatically resolved using specialized helicases. Previous studies showed that DEAH-box Helicase 36 (DHX36/G4R1/RHAU), has the highest specificity and affinity for G4 structures.
