Mutational Profile in Romanian Patients with Hemophilia A.

Hemophilia A (HA) is an X-linked recessive bleeding disorder caused by mutations in the F8 gene, resulting in deficient or dysfunctional factor VIII (FVIII). This study aimed to characterize the mutational profile of HA in Romanian patients using next-generation sequencing (NGS) and multiplex ligation-dependent probe amplification (MLPA). A total of 107 patients were analyzed, revealing pathogenic or likely pathogenic variants in 96.

DNA Sequencing of CD138 Cell Population Reveals TP53 and RAS-MAPK Mutations in Multiple Myeloma at Diagnosis.

Multiple myeloma is a hematologic neoplasm caused by abnormal proliferation of plasma cells. Sequencing studies suggest that plasma cell disorders are caused by both cytogenetic abnormalities and oncogene mutations. Therefore, it is necessary to detect molecular abnormalities to improve the diagnosis and management of MM.

The Significance of CD20 Intensity Variance in Pediatric Patients with B-Cell Precursor Acute Lymphoblastic Leukemia.

B-cell precursor acute lyphoblastic leukemia (ALL) is a common pediatric malignancy and patients may have significant benefits from monoclonal antibodies therapy with increased survival rates. Positive CD20 expression is identified in about half of these patients and its presence may serve as a prognostic factor in disease evolution. We performed a retrospective study including 114 patients diagnosed with B-ALL and evaluated the expression of CD20 through flow cytometry at diagnosis and on day 15.

Controversial Flow Cytometry Monitoring of a Relapse Case of Pediatric T Cell Acute Lymphoblastic Leukemia: A Case Report.

Acute lymphoblastic leukemia (ALL) is the most frequent childhood cancer, with 80-85% represented by B cell ALL and only 15% by T cell ALL. T Cell ALL (T-ALL) carries a more reserved prognosis compared to B Cell ALL (B-ALL) with regard to response to treatment, risk of relapse, and overall survival. Progress made in current monitoring protocols such as flow cytometry immunophenotyping (FCM) and by PCR-based amplification of antigen-receptor genes led to improved management of patients with ALL and superior rates of survival.

Phenotypic assessment of liver-derived cell cultures during expansion.

Liver cells represent an attractive source of cells for autologous regenerative medicine. The present study assesses the liver cells' stability during expansion, as a prerequisite for therapeutic use. The human liver cell cultures in this study were propagated efficiently for at least 12 passages.

Day 15 and Day 33 Minimal Residual Disease Assessment for Acute Lymphoblastic Leukemia Patients Treated According to the BFM ALL IC 2009 Protocol: Single-Center Experience of 133 Cases.

Childhood acute lymphoblastic leukemia (ALL) is a hematologic malignancy characterized by the acquisition of several genetic lesions in the lymphoid progenitors with subsequent proliferation advantage and lack of maturation. Along the years, it has been repeatedly shown that minimal residual disease (MRD) plays an important role in prognosis and therapy choice. The aim of the current study was to determine the prognostic role of MRD in childhood ALL patients in conjunction with other relevant patient and disease characteristics, thus showing the real-life scenario of childhood ALL.

The occurrence of chronic lymphocytic leukemia after chronic phase of chronic myeloid leukemia: case report and literature review.

The occurrence of chronic myeloid leukemia (CML) and chronic lymphocytic leukemia (CLL) in the same patient is a rare event. In published literature, CML diagnosis follows CLL diagnosis or both leukemias are diagnosed simultaneously or rarely, CLL diagnosis follows CML diagnosis. We report the case of one patient with renal adenocarcinoma who was diagnosed with CLL 60 months after CML diagnosis.

Refractory anemia with ringed sideroblasts and thrombocytosis without JAK2 V617F mutation: report of three cases.

In the WHO classification, there is a provisional entity called Myelodysplastic/Myeloproliferative Neoplasm, Unclassifiable (MDS/MPN, U). Refractory anemia with ringed sideroblasts associated with marked thrombocytosis (RARS-T) was included in this category. Recently published studies report a small percentage of patients with RARS-T.
