P REVIOUS OBSERVATIONS have demonstrated the shortened life span of the red cell in patients with paroxysmal nocturnal hemoglohinuria ( PNH ).1.2 Studies of the survival of homologous PNH red cells by the Ashby technic and of autologous PNH cells labeled with radioactive sodium chromate have demonstrated a short and biphasic red cell survival curve in the patient and normal recipient. This life...

Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired clonal stem cell disorder with altered expression of glycosylphosphatidylinositol (GPI)-anchored proteins, resulting in the increased susceptibility of erythrocytes to complement-mediated lysis. This study compared the available laboratory methods for detection of PNH cells and evaluated their utility in routine clinical practice. Fifty p...

The complement system plays a central part in both innate and acquired immunity, but the contribution of complement activation to pathobiology is largely ancillary. An exception to the non-dominant role of complement in disease is the haemolytic anaemia of paroxysmal nocturnal haemoglobinuria (PNH). The intravascular haemolysis that is the clinical hallmark of PNH is a consequence of deficiency...

Thrombosis is one of the most common causes of mortality in Paroxysmal nocturnal hemoglobinuria (PNH), but the predisposing factors for thrombosis are yet to be defined. In this study, we outline the clinical characters and the susceptible genes which lead to thrombotic formation in 104 patients with PNH. The results displayed that the genotypes with minor alleles of rs495828 or rs2519093 in th...

Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired stem-cell disorder in which the glycolipid-anchored membrane proteins, including the cell-surface complement inhibitors, CD55 and CD59, are partially or completely deleted from the plasma membranes of mature blood cells. To gain insight into the pathogenesis of thrombosis that is frequently observed in this disorder, the procoagulant resp...

By WILLIAM H. CROSBY, MAJOR, MC, AUS P AROXYSMAL nocturnal hemoglobinuria (Marchiafava-Micheli syndrome) is a rare form of chronic hemolytic anemia characterized by the presence of abnormal erythrocytes which are susceptible to lysis by a factor normally present in plasma or serum. It has recently been suggested that this factor resembles closely or may even be identical with the coagulation ac...

background: we aimed to study the curative effects of botulinum a toxin (btx-a) on the treatment of post-herpetic neuralgia (pnh). methods: we enrolled 58 pnh patients and treated them with hypodermic injection of btx-a in xiangyang no.1 people’s hospital, hubei university of medicine, hubei, china. we measured and compared the visual analog score (vas), neuropathy pain scale (nps), quality of ...

Este artículo describe las experiencias en la salud pública brasileña durante peor crisis sanitaria de historia Brasil, debido a amenazas del COVID-19. Destaca el trabajo sus múltiples dimensiones y matices. matices, enfatizando Política Humanización SUS (PNH) que reconoce condiciones desfavorables opresivas salud. Rechaza, por un lado, posiciones victimizadas o pasivas veces asumen los trabaja...

Cytogenetic studies showed both 45XO and 46XY clones in the bone marrow of a 76-yr-old male with a 17-yr history of paroxysmal nocturnal hemoglobinuria (PNH). 55Fe incorporation studies demonstrated that both clones involved the hematopoietic stem cells. The loss of the Y chromosome may reflect an aging phenomenon, rather than be related to the PNH.
