Severe Dengue Associated With Hemophagocytic Lymphohistiocytosis (HLH) in an Adult ICU.

Background: Dengue virus infection is a growing global health concern, especially in tropical and subtropical regions. Dengue fever is commonly self-limiting, but sometimes, rare complications such as hemophagocytic lymphohistiocytosis (HLH) may occur, leading to fatal outcomes. HLH is a rare, hyperinflammatory syndrome marked by excessive immune activation, which can result in multiorgan failure and death.

A Novel 5-Probe FISH Strategy is Better Equipped for a More Comprehensive and Cost-Effective Risk Stratification of BCP-ALL.

Objective: The modern treatment protocols in B-cell precursor acute lymphoblastic leukemia (BCP-ALL) are based on the disease's genetic characteristics and response to treatment. We propose a novel five-probe FISH strategy to risk stratify the BCP-ALL and compare its ability with the triple trisomy probe strategy to detect high hyperdiploidy.

Methods: All newly diagnosed BCP-ALL cases were investigated using a five-probe FISH panel that included probes targeting BCR::ABL1 fusion, ETV6::RUNX1 fusion, and break-apart probes for KMT2A, IgH, and CRLF2 rearrangements.

A Comparative Analysis of Freelite and N Latex FLC Assay for the sFLC Measurements in Suspected Patients of Monoclonal Gammopathy.

With the introduction of newer platforms for sFLC estimation, more comparative attempts are required to establish an assay-specific reference range, that can be used in the day-to-day clinical management of the patients, as the revised criteria for the diagnosis of myeloma recommend the use of involved Free light chain (FLC)/uninvolved FLC ratio as myeloma defining event, solely relying on Freelite assay.

AAV mediated genome engineering with a bypass coagulation factor alleviates the bleeding phenotype in a murine model of hemophilia B.

It is crucial to develop a long-term therapy that targets hemophilia A and B, including inhibitor-positive patients. We have developed an Adeno-associated virus (AAV) based strategy to integrate the bypass coagulation factor, activated FVII (murine, mFVIIa) gene into the Rosa26 locus using Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9 mediated gene-editing. AAV vectors designed for expression of guide RNA (AAV8-gRNA), Cas9 (AAV2 neddylation mutant-Cas9), and mFVIIa (AAV8-mFVIIa) flanked by homology arms of the target locus were validated in vitro.

Peripheral blood quantitation of CD26 positive leukemic stem cells as a predictor of tyrosine kinase inhibitor response in chronic myeloid leukemia.

Introduction: Leukemic stem cells (LSCs) are the transcriptionally low/silent cells which are resistant to the tyrosine kinase inhibitor. These have been found to play a pivotal role in disease relapse in chronic myeloid leukemia (CML) cases. The present study evaluated the correlation of absolute CML-LSC count in the peripheral blood (PB) at diagnosis and achievement of major molecular response (MMR) at 12 months in patients of CML-CP.

Role of miRNAs in T-cell activation and Th17/Treg-cell imbalance in acquired aplastic anemia.

Background: Altered T-cell repertoire with an aberrant T-cell activation and imbalance of the Th17/Treg cells has been reported in acquired aplastic anemia (aAA). miRNAs are well known to orchestrate T-cell activation and differentiation, however, their role in aAA is poorly characterized. The study aimed at identifying the profile of miRNAs likely to be involved in T-cell activation and the Th17/Treg-cell imbalance in aAA, to explore newer therapeutic targets.

CD157 Can Replace CD24 and CD14 in a Single-Tube Flow-Cytometric Assay to Detect Paroxysmal Nocturnal Hemoglobinuria (PNH) Clones on Both Neutrophils and Monocytes: A Prospective Study From North India.

Introduction As per current guidelines, detection of paroxysmal nocturnal hematuria (PNH) clones on leucocytes requires the demonstration of the loss of at least two glycosyl-phosphatidyl-inositol (GPI)-linked molecules on both neutrophils and monocytes by flow cytometry. CD24 and CD14 are GPI-linked molecules expressed on neutrophils and monocytes respectively, whereas another GPI-linked molecule, CD157, is expressed on both neutrophils and monocytes. This prospective study evaluated the ability of CD157 to replace both CD24 and CD14 in a single-tube flow-cytometric assay to detect PNH clones on both neutrophils and monocytes.
