Aplastic anemia (AA) may evolve into clonal diseases like myelodysplastic syndrome (MDS) and acute myeloblastic leuke¬mia (AML). Monosomy 7 is a poor prognostic chromosomal abnormality commonly associated with therapy related MDS and secondary AML. It has also been associated with leukomogenic transformation in AA. We present here two adult ma¬le patients with acquired severe AA. Both patients ...
Between 1960 and 1977, 50 patients with agnogenic myeloid metaplasia were splenectomized. Twenty-five of 26 patients with painful splenomegaly, 4 of 9 patients with refractory hemolytic anemia, 4 of 10 patients with refractory thrombocytopenia, and 4 of 4 patients with portal hypertension showed significant benefit from the procedure. There were five immediate postoperative deaths. Four of thes...
A 58-year-old woman was admitted with refractory fever despite receiving broad-spectrum antibiotics. She had hypoxemia, severe anemia, elevated levels of serum lactic dehydrogenase and soluble interleukin-2 receptor, and a positive direct Coombs test, which suggested an underlying autoimmune hemolytic anemia (AIHA). Chest computed tomography (CT) showed no abnormal findings, but she had hypoxia...
Thrombotic thrombocytopenic purpura (TTP) is a heterogeneous disease primarily characterized by thrombocytopenia and microangiopathic hemolytic anemia. Therapeutic plasma exchange has dramatically improved mortality, allowing for emergence of refractory, relapsing, and atypical presentations. In this article, we describe four cases of TTP presenting with minimal schistocytes, mild elevation of ...
Here we describe the case of an unfortunate 26 year old woman who developed a fatal combination of autoimmune hemolytic anemia (AIHA), hemophagocytic lymphohistiocytosis (HLH), and thrombotic thrombocytopenic purpura (TTP). Her initial clinical picture looked that of typical autoimmune hemolytic anemia but when she was refractory to standard therapy and her course progressed, alternative diagno...
Recently, immunotherapeutic drugs, including PD-1 inhibitors (nivolumab, pembrolizumab), PD-L1 inhibitors (atezolizumab, avelumab), and CTLA4 inhibitors (ipiliumumab), have emerged as important additions to the armamentarium against certain malignancies and have been incorporated into therapeutic protocols for first-, second-, or third-line agents for these metastatic cancers. Immune checkpoint...
Histiocytic sarcoma (HS) rarely involves extranodal sites, such as the spleen. We report a unique pediatric case of massive splenomegaly and refractory Coombs negative hemolytic anemia (CNHA) secondary to HS. The CNHA resolved completely after an emergent splenectomy. Next generation sequencing (NGS) revealed novel ASXL1, PTPN11, KIT, and TP53 mutations, unmasking a clonal heterogeneity within ...
(Case 1) A 13-years-old female had multiple arthralgia and butterfly rush, when she admitted in our hospital in May 2001. Nephropathy, hemolytic anemia (Hb 6.3 g/dl and direct Coombs 3+) and high titers of antinuclear antibodies and anti-ds-DNA antibody were disclosed and she was diagnosed as systemic lupus erythematosus (SLE). Although combination therapy of PSL 60 mg/day with a steroid pulse ...
We investigated the efficacy of arsenic trioxide (ATO) in patients with refractory severe aplastic anemia (SAA). A total of 5 consecutive adults were enrolled. The patients received ATO at a dose of 0.15 mg/kg intravenously daily for 5 days every week for 8 weeks. If necessary, a second course was performed after an interval of one week. All patients achieved clinically significant responses to...
