Background: CIVID-19 due to SARS-CoV-2 was first described in the city of Wuhan in China and spread around the world turning into a pandemic. COVID-19 can affect different organ systems, including the oral mucosa.
OBJECTIVE
Paroxysmal nocturnal hemoglobinuria (PNH) is a clonal disorder due to a PIG-A gene mutation, resulting in deficient expression of GPI-anchored-proteins. Both immune-mediated suppression of hematopoiesis and cytokine alterations have been reported in aplastic anemia, a disease closely
Paroxysmal nocturnal hemoglobinuria (PNH) is a clonal, acquired hematopoietic disorder characterized by a phosphatidylinositol (PI) glycan-A gene mutation, which impairs the synthesis of the glycosyl-PI (GPI) anchor, thus causing the absence of all GPI-linked proteins on the membrane of the
Hemoglobin and myoglobin heme pigments and iron have acute and chronic nephrotoxic effects, which are often associated with massive hemolysis and rhabdomyolysis. We report a patient with a myelodysplastic syndrome and paroxysmal nocturnal hemoglobinuria phenotype who developed an acute renal failure
Acute renal failure is a known complication during hemolytic crisis in paroxysmal nocturnal hemoglobinuria (PNH). However, chronic renal failure is rare despite the well-known spectacular hemosiderosis of the kidneys due to chronic hemolysis. Here, we report about a 74-year-old man with PNH who
Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, life-threatening hematologic stem cell disorder characterized by hemoglobinuria, thrombosis, and tendency for bone marrow failure. The rare incidence of PNH in children, its nonspecific clinical presentation, and occasional absence of
Paroxysmal nocturnal hemoglobinuria (PNH) is a rare hematopoietic stem cell disorder characterized by hemolytic anemia, hemoglobinuria, bone marrow failure, and hypercoagulability. Thrombosis is the leading cause of mortality and occurs in one-half of PNH patients, with the hepatic veins being the
Paroxysmal nocturnal hemoglobinuria (PNH) is a rare disorder characterized by pancytopenia, hemolysis, and thrombosis. Abdominal vein thrombosis is a life-threatening manifestation of this disease. We present a patient with complete spleen necrosis due to thrombosis of the splenic vessels. After
A 66-year-old woman complained of fever, sore throat, and neck pain due to pharyngitis and painful lymph node swelling. CBC revealed severe pancytopenia and markedly hypocellular marrow. The administration of antibiotics and granulocyte-colony stimulating factor (G-CSF) successfully ameliorated the
