myelosuppression

Acute myelogenous leukemia (AML) has a poor prognosis in patients who are ineligible for intensive chemotherapy. The combination of azacitidine and venetoclax has been shown to have high overall efficiency and remission rates, even in patients ineligible for aggressive chemotherapy. However, myelosuppression is often prolonged after treatment, and infection can also occur. Severe myelosuppression is often addressed by dose titration, but specific dose titration methods have not been clarified. We used the standard induction therapy with azacitidine plus venetoclax, and if blasts decreased to 20% or less, switched to 7+7 therapy to shorten venetoclax to 7 days starting from the next cycle...

OBJECTIVES: To explore the association between palbociclib and related adverse events (AEs) in the real world through U.S. Food and Drug Administration Adverse Event Reporting System (FAERS) database. METHODS: The signal strength of palbociclib-related AEs was done by disproportionality analysis. Clinical priority of palbociclib-related AEs was scored and ranked by assessing five different features. Serious and non-serious cases were compared by Mann-Whitney U test or Chisquared (χ2 ) test...

Sickle cell disease (SCD) poses a significant health challenge and therapeutic approaches often target fetal hemoglobin (HbF) to ameliorate symptoms. Hydroxyurea, a current therapeutic option for SCD, has shown efficacy in increasing HbF levels. However, concerns about myelosuppression and thrombocytopenia necessitate the exploration of alternative compounds. Heme-regulated inhibitor (HRI) presents a promising target for pharmacological intervention in SCD due to its association with HbF modulation. This study screened compounds for their potential inhibitory functions against HRI...

Esophageal cancer, which is common among the elderly, has the poorest prognosis among gastrointestinal cancers. Previously, we demonstrated that ferrichrome, produced by the probiotic Lactobacillus casei , exhibited anti-tumor effects in various gastrointestinal cancers, including colorectal and gastric cancers, with minimal effects on non-cancerous intestinal cells. However, it remains unclear whether ferrichrome exerts anti-tumor effects in esophageal cancer. A sulforhodamine B assay revealed that ferrichrome suppressed esophageal adenocarcinoma (OE33, OE19) and squamous cell carcinoma (KYSE70) cells...

Doxorubicin (DOX) is a prevalent anticancer agent; however, it is unfortunately characterized by high cardiotoxicity, myelosuppression, and multiple other side effects. To overcome DOX limitations, two novel pyridoxine-derived doxorubicin derivatives were synthesized (DOX-1 and DOX-2). In the present study, their antitumor activity and mechanism of action were investigated. Of these two compounds, DOX-2, in which the pyridoxine fragment is attached to the doxorubicin molecule via a C3 linker, revealed higher selectivity against specific cancer cell types compared to doxorubicin and a promising safety profile for conditionally normal cells...

As a complementary and alternative therapy, traditional Chinese medicine (TCM) has been playing a significant role in gastric cancer treatment. Data from individual systematic reviews have not been comprehensively summarized, and the relationship between certain interventions and outcomes are ill-defined. This study aimed to analyze the advantages of TCM interventions for gastric cancer by the method of evidence mapping. We searched PubMed, Embase, Web of Science, China National Knowledge Infrastructure, Chinese Scientific Journals Database, and Wanfang Database for systematic reviews of TCM treating gastric cancer up to December 31, 2023...

METHODS: A retrospective analysis was performed on 42 patients with HIV-DLBCL who were admitted to the Infectious Diseases Department of Yunnan Provincial Infectious Diseases Hospital from January 2018 to December 2020. 14 cases (including 1 case in stage II and 13 cases in stage III/IV) were treated with R-CHOP, 24 cases (including 1 case in stage II and 23 cases in stage III/IV) were treated with R-DAEPOCH, and 4 cases (including 1 case in stage II and 3 cases in stage III/IV) were treated with EPOCH...

OBJECTIVES: Secondary hemophagocytic lymphohistiocytosis (sHLH) is a cytokine-driven inflammatory syndrome that is associated with substantial morbidity and mortality and frequently leads to ICU admission. Overall survival in adults with sHLH remains poor, especially in those requiring intensive care. Classical chemotherapeutic treatment exhibits myelosuppression and toxicity. Recently, inhibition of Janus kinase signaling by ruxolitinib has shown efficacy in pediatric HLH. We therefore aimed to determine the activity and safety of a ruxolitinib-based regimen, in critically ill adults with sHLH...

BACKGROUND: Patients with relapsed intracranial germinoma can achieve durable remission with standard chemotherapy regimens and/or reirradiation; however, innovative therapies are required for patients with relapsed and/or refractory intracranial nongerminomatous germ cell tumors (NGGCTs) due to their poor prognosis. Improved outcomes have been reported using reinduction chemotherapy to achieve minimal residual disease, followed by marrow-ablative chemotherapy (HDCx) with autologous hematopoietic progenitor cell rescue (AuHPCR)...

BACKGROUND AND OBJECTIVES: To evaluate the potential benefits of Bacteroides fragilis 839 (BF839), a next-generation probiotics, in reducing myelosuppression and gastrointestinal toxicity associated with chemotherapy in breast cancer patient. METHODS AND STUDY DESIGN: 40 women with early breast cancer were randomly assigned to the BF839 (n=20) or placebo (n=20) during the administration of adjuvant chemotherapy (4 cycles of epirubicin 100mg/m2 and cyclophosphamide 600mg/m2)...

Thrombopoietin (Tpo), which binds to its specific receptor, the Mpl protein, is the major cytokine regulator of megakaryopoiesis and circulating platelet number. Tpo binding to Mpl triggers activation of Janus kinase 2 (Jak2) and phosphorylation of the receptor, as well as activation of several intracellular signalling cascades that mediate cellular responses. Three tyrosine (Y) residues in the C-terminal region of the Mpl intracellular domain have been implicated as sites of phosphorylation required for regulation of major Tpo-stimulated signalling pathways: Mpl-Y565, Mpl-Y599 and Mpl-Y604...

A patient with disseminated nocardiosis developed pancytopenia after treatment with recombinant interferon gamma (IFN-γ). While no prior clinical reports link pancytopenia to IFN-γ, our observations align with basic research on myelosuppressive effects of IFN-γ. Adjunctive IFN-γ may improve standard nocardiosis therapy, but vigilant monitoring of its hematological effects is necessary.

BACKGROUND: Bruton's tyrosine kinase inhibitors (BTKis) are targeted treatments for B-cell tumors but have significant side effects. This study assesses and contrasts the side effects of BTKis alone and its four combination therapies. RESEARCH DESIGN AND METHODS: The reporting odds ratio (ROR) was used to analyze the data on three BTKis monotherapies and combinations of ibrutinib with rituximab, obinutuzumab, venetoclax, and lenalidomide in the FDA Adverse Event Reporting System (FAERS) database up to December 2022...

Sofosbuvir is one of the crucial drugs used in the treatment of chronic hepatitis C virus (HCV) in adults and children with compensated liver disease, including cirrhosis. It may be used alone or with other drugs. Ribavirin is an antiviral medication used to treat HCV infection. It is not effective when used alone and must be used in combination with other medications, such as sofosbuvir. This study pertains to a comprehensive assessment of the deleterious effects of sofosbuvir (an antiviral drug against chronic HCV) or sofosbuvir combined with ribavirin (an antiviral drug against RNA and DNA viruses) on several biological activities of the body, including hematological, hormonal, biochemical, histological, and immunohistochemical examinations during a long-standing period on male healthy rats...
