There are no data on PNH among Omani patients. Methods We performed a retrospective review of all patients tested for PNH by flow cytometry at the Sultan Qaboos University Hospital between 2012 and 2019. Manifestations, treatment modalities and outcomes were assessed. Results Total of 10 patients were diagnosed or were on follow up for PNH (median age 22.5 years). Clinical manifestations included fatigue (80%) and anemia (70%). There were six patients who had classical PNH with evidence of hemolysis, three patient had PNH in the context of aplastic anemia, and one patient with subclinical PNH. The median reported total type II+III clone size was 95.5 (range 1.54-97) in neutrophils (FLAER/CD24) and 91.6 (range 0.036-99) in monocytes (FLAER/CD14). There were four patients who were found to have a clone size > 50% at time of diagnosis. The median follow up of the patients were 62 months (range: 8-204). -
Increased Red Cell Distribution Width in Fanconi Anemia: a Novel Marker Of
Sousa et al. Orphanet Journal of Rare Diseases (2016) 11:102 DOI 10.1186/s13023-016-0485-0 RESEARCH Open Access Increased red cell distribution width in Fanconi anemia: a novel marker of stress erythropoiesis Rosa Sousa1, Cristina Gonçalves2, Isabel Couto Guerra3, Emília Costa3, Ana Fernandes4, Maria do Bom Sucesso4, Joana Azevedo5, Alfredo Rodriguez6, Rocio Rius6, Carlos Seabra7, Fátima Ferreira8, Letícia Ribeiro5, Anabela Ferrão9, Sérgio Castedo10, Esmeralda Cleto3, Jorge Coutinho2, Félix Carvalho11, José Barbot3 and Beatriz Porto1* Abstract Background: Red cell distribution width (RDW), a classical parameter used in the differential diagnosis of anemia, has recently been recognized as a marker of chronic inflammation and high levels of oxidative stress (OS). Fanconi anemia (FA) is a genetic disorder associated to redox imbalance and dysfunctional response to OS. Clinically, it is characterized by progressive bone marrow failure, which remains the primary cause of morbidity and mortality. Macrocytosis and increased fetal hemoglobin, two indicators of bone marrow stress erythropoiesis, are generally the first hematological manifestations to appear in FA. However, the significance of RDW and its possible relation to stress erythropoiesis have never been explored in FA. In the present study we analyzed routine complete blood counts from 34 FA patients and evaluated RDW, correlating with the hematological parameters most consistently associated with the FA phenotype. Results: We showed, for the first time, that RDW is significantly increased in FA. We also showed that increased RDW is correlated with thrombocytopenia, neutropenia and, most importantly, highly correlated with anemia. Analyzing sequential hemograms from 3 FA patients with different clinical outcomes, during 10 years follow-up, we confirmed a consistent association between increased RDW and decreased hemoglobin, which supports the postulated importance of RDW in the evaluation of hematological disease progression. -

Personal Statement I have been involved for over 25 years in research on the autoimmune aspects of type 1 diabetes (T1D) and inflammation in type 2 diabetes (T2D). While in the Janeway Laboratory for my postdoctoral we were the first lab to show that islets in nonobese diabetic (NOD) mice did not express MHC class II molecules, but that expression of MHC class I increased significantly during the development of diabetes. Therefore, we established that beta cells were not presenting antigen to CD4 T cells (last publication listed). I have worked actively on autoimmunity in type 1 diabetes as evidenced by publications on autoantigens (insulin, glutamic acid decarboxylase), autoantibodies (anti-insulin receptor), T cells (CD8 and CD4), T cell clones and hybridomas (anti-insulin, antiGAD), humanized transgenic mice expressing the diabetes susceptibility DQ8 molecule that turned out to be an autoimmune model of human myocarditis, and the role of the insulin receptor in diabetes development which was supported by NIH. -

Blueprint Genetics Anemia Panel
Anemia Panel Test code: HE0401 Is a 88 gene panel that includes assessment of non-coding variants. Is ideal for patients suspected to have hereditary anemia who have had HBA1 and HBA2 variants excluded as the cause of their anemia or patients suspected to have hereditary anemia who are not suspected to have HBA1 or HBA2 variants as the cause of their anemia. The genes on this panel are included in the Comprehensive Hematology Panel. Is not recommended for patients suspected to have anemia due to alpha-thalassemia (HBA1 or HBA2). These genes are highly homologous reducing mutation detection rate due to challenges in variant call and difficult to detect mutation profile (deletions and gene-fusions within the homologous genes tandem in the human genome). Is not recommended for patients with a suspicion of severe Hemophilia A if the common inversions are not excluded by previous testing. An intron 22 inversion of the F8 gene is identified in 43%-45% individuals with severe hemophilia A and intron 1 inversion in 2%-5% (GeneReviews NBK1404; PMID:8275087, 8490618, 29296726, 27292088, 22282501, 11756167). This test does not detect reliably these inversions. About Anemia Anemia is defined as a decrease in the amount of red blood cells or hemoglobin in the blood. The symptoms of anemia include fatigue, weakness, pale skin, and shortness of breath. Other more serious symptoms may occur depending on the underlying cause. The causes of anemia may be classified as impaired red blood cell (RBC) production or increased RBC destruction (hemolytic anemias). Hereditary anemia may be clinically highly variable, including mild, moderate, or severe forms. -

Aberrant T or B cells or innate immune responses are variously involved in the pathophysiology of BMF, and hematological improvement after standard immunosuppressive or anti-complement therapies is the main indirect evidence of the central role of the immune system in BMF development. As part of this immune derangement, pro-inflammatory cytokines play an important role in shaping the immune responses and in sustaining inflammation during marrow failure. In this review, we summarize current knowledge of cytokine signatures in BMF syndromes.
