Due to demographic aging of the general population, cytopenia and especially anemia unknown origin is on rise, with an increasing need for a structured clinical assessment these conditions. The advent next-generation sequencing (NGS) in our practice has facilitated detection clonal hematopoiesis (CH), which present more than 20−40% individuals above 80 years age. This poses unprecedented challe...

Objective: Thrombotic thrombocytopenic purpura (TTP) is the most malignant variant of microangiopathy that usually presents by typical symptoms including thrombocytopenia, hemolytic anemia, neurological abnormalities, fever and renal impairment. Report of the Case: We report a 12-year-old male presented by cytopenia, fever, purpura on his extremities, seizure and lethargy. Peripheral blood sm...

Previous studies of T cell reconstitution following allogeneic stem cell transplantation have described long-lasting T cell defects, including decreased levels of autocrine proliferating CD4+ T cells. However, T cell functions during the early phase of conditioning-induced, pre-engraftment pancytopenia have not been characterized previously. We used a whole blood assay to investigate T cell pro...

Although myelodysplastic syndromes are heterogeneous disorders comprising a benign subset of bone marrow failure similar to aplastic anemia, no laboratory test has been established to distinguish it from bone marrow failures that can evolve into acute myeloid leukemia. Plasma thrombopoietin levels were measured in 120 patients who had myelodysplastic syndrome with thrombocytopenia (< 100 × 10(9...

Little information exists about the association of anti-SSA/Ro60 and anti-Ro52/TRIM21 with systemic lupus erytematosus (SLE) features. In this work, we analysed the associations of both anti-Ro reactivities with clinical and immunological manifestations in 141 SLE patients. Photosensitivity and xerophtalmia/xerostomia were found to be positively associated with both anti-SSA/Ro60 (P = 0.024 and...

The evaluation of hematologic disorders after solid organ transplantation (SOT) must take into account issues unique to the post-transplant setting that influence the development of anemia and single or multi-lineage cytopenias. Attention to the time of onset of cytopenia(s) is important, because the disorders of passenger lymphocyte syndrome, transplant-related thrombotic microangiopathy, hemo...

Neutrophil function studies have been carried out in a series of 44 patients with primary myelodysplastic syndromes (MDS). In vitro tests of phagocytosis and killing of Candida guilliermondii and Staphylococcus aureus identified 13 patients with abnormal neutrophil function at presentation and a further 10 who developed abnormalities during the course of their disease. The incidence of defectiv...

A 75-year-old woman taking the nonsteroidal anti-inflammatory drug diclofenac (DCF) presented with acute Coombs-positive hemolytic anemia and subsequently developed renal failure. A drug-dependent antibody specific for red blood cells (RBCs) could not be demonstrated by in vitro testing with DCF. However, her serum was found to contain an IgM antibody that reacted strongly with RBCs in the pres...

BACKGROUND AND PURPOSE Lupus anticoagulants (LACs) are frequently found in patients with human immunodeficiency virus (HIV). This study was designed to examine the prevalence of LACs and its significance in HIV-infected Nigerian patients. METHODS LACs were assayed, and complete blood count and direct Coombs' test (DCT) were performed for 155 participants. Patients with other conditions known ...
