Paroxysmal nocturnal hemoglobinuria PNH is a rare, acquired hematologic disorder with variable clinical manifestations. The untreated disease is characterized by intravascular haemolysis, thrombophilia e. PNH phenotype is mainly caused by one or more acquired somatic mutation s in the phosphatidylinositol glycan class A PIG-A gene at the level of the pluripotent hematopoietic stem cell of the bone marrow. Treatment is symptom-oriented. In asymptomatic patients, a wait-and-see approach could be performed. In these patients, a prophylactic anticoagulation may be considered. In symptomatic patients, the development of targeted drug inhibition of the terminal complement cascade has led to a significant improvement in clinical symptoms and prevention of disease-related complications. Compared to historical controls, the survival time of patients with hemolytic PNH is now significantly improved. The first terminal complement inhibitor, Eculizumab, was approved infollowed by Ravulizumab in and Crovalimab in Pegcetacoplan, the first proximal complement inhibitor, became available in Danicopan and Iptacopan can also be used in following approval. Other newly developed complement inhibitors are still undergoing clinical trials. Paroxysmal nocturnal hemoglobinuria PNH is a rare, acquired disease of bone marrow hematopoietic stem cells that belongs to the group of bone marrow failure syndromes BMFS. The disease has a variable clinical course and is characterized by intravascular hemolysis, thrombophilia with thrombosis in typical and atypical locations and a variable degree of cytopenia [ 12 ]. There are no reliable epidemiological data available for the prevalence and incidence of PNH in Germany. Due to its clinical heterogeneity, it can be assumed that this disease might be "underdiagnosed" [ 3 ]. The basis at the cellular level in paroxysmal nocturnal hemoglobinuria is a mutation in the X-linked PIG-A gene, which prevents the biosynthesis of the glycosylphosphatidylinositol GPI anchor molecule [ 4 ]. In single individual cases, GPI deficiency arises due to hereditary mutations in autosomal localized genes such as PIG-T, in Ulrike 58 Österreich Aachen Dating the second allele is switched off by an additional somatic mutation and thus the complete biosynthesis step is interrupted leading to a PNH phenotype in these cells [ 56 ]. GPI deficiencies are found at the level of multipotent hematopoietic stem cells of the bone marrow [ 78 ]. The acquired somatic mutation s do not affect all bone marrow stem cells, resulting in a so-called mosaic situation. Very low numbers of GPI-deficient cells with the corresponding mutation can also be detected in healthy subjects using high-resolution detection methods [ 9 ]. In addition, previous observations show that at the stem cell level, GPI-deficient stem cells in individual PNH patients have an intrinsic growth advantage over normally expressing stem cells due to cytogenetic changes and thus exert clonal dominance in the bone marrow [ 11 ]. Recent studies using next generation sequencing NGS have shown that the mechanism of clonal expansion is much more complex in most PNH patients. In addition to the characteristic PIG-A mutations, other somatic mutations in myeloid genes activating mutations comparable to those in other Ulrike 58 Österreich Aachen Dating diseases [ 12 ] as well as mutations in genes involved in immune recognition such as HLA molecules 'immune escape mutations' have been found in PNH patients. Time line studies on quantitative distribution of these individually mutated competing clones have shown that a complex clonal hierarchy - caused by the interaction of myeloid progenitor cells and the immune system - is usually present in the bone marrow of PNH patients [ 13 ]. The consequence of GPI deficiency on a significant proportion of peripheral blood cells is a lack of complement-regulating proteins. In particular, CD55, the so-called 'decay accelerating factor DAF ' and CD59, the 'membrane inhibitor of reactive lysis MIRL ' [ 14 ] are to be mentioned. In the case of complement activation, erythrocytes in particular are sensitive to terminal complement-mediated lysis due to the constitutive absence of transmembrane-anchored Complement-regulating surface molecules. Since almost all PNH-specific symptoms have also been described in a patient with an isolated CD59 defect, the CD59 molecule plays a central role in the clinical symptoms as a regulator of the membrane attack complex MAC [ 14 ]. However, there is a correlation between the occurrence of hemoglobinuria and the size of the PNH clone, i. The classic characteristics of chronic hemolytic anemia are weakness, fatigue and exertional dyspnea. The extent of fatigue is not strictly linearly correlated with the extent of anemia, but with the extent of hemolysis Ulrike 58 Österreich Aachen Dating the size of the PNH clone. An abnormal depletion of nitric oxide correlates with the intravascular release of hemoglobin, on the one hand due to NO consumption through the metabolization of hemoglobin to methemoglobin. On the other hand, there is also a release of erythrocytic arginase, which reduces arginine as a starting substance for de novo NO production [ 15 ]. This is associated with endothelial cell dysfunction and platelet activation. The abnormal fatigue of PNH patients can also be linked to this depletion [ 15 ]. Thromboembolic complications are the most clinically relevant complication for patients with PNH and are the main cause of the increased morbidity and mortality of this disease [ 3 ]. The dysfunction caused by NO depletion is seen as part of thrombophilia, but coagulation-activating erythrocyte microvesicles and even inhibition of ADAMTS13 have also been identified. However, none of these factors alone can sufficiently explain the abnormal thrombophilia in patients with PNH [ 1617 ].
