Successful application of PD-1 knockdown CLL-1 CAR-T therapy in two AML patients with post-transplant relapse and failure of anti-CD38 CAR-T cell treatment.

Patients with relapsed/refractory acute myeloid leukemia (R/R AML) often show resistance to chemotherapy and have dismal outcomes. Therefore, it is urgent to develop new treatment strategies to address this problem. With tremendous achievement of chimeric antigen receptor T cells (CAR-T) therapy against B-cell malignancies, many efforts have been devoted to developing CAR-T therapy for R/R AML but with limited success, in part owing to a lack of specific targets.

Haploidentical CD7 CAR T-cells induced remission in a patient with TP53 mutated relapsed and refractory early T-cell precursor lymphoblastic leukemia/lymphoma.

Patients with relapsed/refractory early T-cell precursor lymphoblastic leukemia/lymphoma (ETP-ALL/LBL) respond poorly to traditional therapy and have dismal prognosis. CD7 is a promising therapeutic targets for chimeric antigen receptor modified T cell therapy (CART) due to its widely expression in almost all T-cell malignancies. Here we present the anti-CD7 CART therapy in a 11-year-old male with TP53 mutated relapsed/refractory ETP-ALL/LBL.

[The Effect of Immunized Platelet Transfusion Refractoriness on Allo-HSCT Patients with Malignant Hematological Diseases].

Objective: To investigate the characteristics of platelet antibody in patients with hematological diseases, so as to research the effect of immunized platelet transfusion refractoriness (PTR) on the prognosis of allogeneic hematopoietic stem cell transplantation (allo-HSCT) recepients with malignant hematological diseases patients.

Methods: The clinical data of platelet antibody positive patients tested by Capture-P in the First Affiliated Hospital of Soochow University from July 1, 2014 to July 1, 2019 were retrospectively analyzed, including sex, age, disease, platelet transfusion assessments, CD34 cells, transplant prognosis, and so on.

Results: In 5 years, 913 (7.

Development of acquired factor V inhibitor after treatment with ceftazidime: a case report and review of the literature.

We report the case of a 59-year-old Chinese man who showed an asymptomatic coagulation factor V deficiency pattern after second intravenous treatment with ceftazidime. Normal pooled plasma failed to correct the abnormalities in a mixing test, and the presence of factor V inhibitor was confirmed by the Bethesda method. The coagulopathy was not corrected by transfusion of fresh frozen plasma and prothrombin complex concentrate, but rather by treatment with prednisone and withdrawal of dubious drugs.

Valproic acid-associated low fibrinogen and delayed intracranial hemorrhage: case report and mini literature review.

A 41-year-old male had suffered from gradual hearing loss in his right ear for 2 years. Head computed tomography and magnetic resonance imaging scans showed a neoplasm in the cerebellopontine angle region, which was confirmed by the diagnosis of acoustic neurilemmoma by pathological findings after surgery. Following surgery, he routinely received valproic acid (VPA) to prevent seizures.

Clinical study of thalidomide combined with dexamethasone for the treatment of elderly patients with newly diagnosed multiple myeloma.

Objective: To investigate the relationship between the efficacy and safety of different doses of thalidomide (Thal) plus dexamethasone (Dex) as the initial therapy in elderly patients with newly diagnosed multiple myeloma (MM).

Methods: Clinical data of 28 elderly patients with newly diagnosed MM who underwent the TD regimen as the initial therapy were analyzed retrospectively. The patients were divided into two groups according to the maximal sustained dose of Thal: lower dose (group A) and higher dose (group B).
