Anemia after kidney transplant is not uncommon. This paper reports a case of unexplained anemia in a kidney transplant recipient that persisted for more than two months, and that did not respond to recombinant human erythropoietin treatment but was successfully treated after diagnosing Parvovirus B19 ParvoV B19 infection. A middle-aged male underwent living-unrelated kidney transplantation from Pakistan in April He was on triple immuno-suppression therapy consisting of prednisolone, tacrolimus, and mycophenolate mofetil.
Fifth and sixth diseases: More than a fever and a rash
Transient Aplastic Crisis
Human parvovirus B19 B19 infection causes human bone marrow failure, by affecting erythroid-lineage cells which are well-known target cells for B The anaemia induced by B19 infection is of minor clinical significance in healthy children and adults, however, it becomes critical in those afflicted with haemolytic diseases. This condition is called transient aplastic crisis, and the pathogenesis is explained by the short life-span of red blood cells. Similarly, fetuses are thought to be severely affected by Bintrauterine infection in the first and second trimester, as the half-life of red blood cells is apparently shorter than RBC at the bone marrow haematopoietic stage.
Human Parvovirus B19 has been linked to a variety of diseases. One of the most common complications is transient aplastic crisis in patients with chronic hemolytic anemia. Very few case reports have implicated this virus as a putative etiology behind hepatitis and severe aplastic anemia in immuno competent individuals. We report a case of severe aplastic anemia in a previously healthy adult female due to acute parvovirus B19 infection.
Although there are several case reports of human parvovirus B19 infection in patients with hereditary spherocytosis, no systematic reviews of adult patients with hereditary spherocytosis with human parvovirus B19 infection have been published as clinical case reports. In this study, we report a case of aplastic crisis due to human parvovirus B19 infection in an adult patient with hereditary spherocytosis. A year-old woman with hereditary spherocytosis and gallstones was admitted because of rapid progress in marked anemia and fever. Although empiric antibiotic therapy was prescribed, her clinical symptoms and liver function test worsened.
