  • Title: Parvovirus B19-associated transient red cell aplasia in children: the role of bone marrow examination in unusual presentations.
    Author: Garewal G, Ahluwalia J, Das R, Marwaha RK.
    Journal: Pediatr Hematol Oncol; 2004 Sep; 21(6):505-11. PubMed ID: 15552814.
    Abstract:
    Human parvovirus B19 (PV B19) infection in children commonly presents as fifth disease. Transient red cell crisis, the other manifestation of PV B19 infection, is usually reported in children with chronic hemolytic anemia, with a worsening of the anemia. However, this condition may pass unrecognized in children without an underlying hemolytic disorder, since the anemia may be of a short duration and self-limiting. The authors report 3 cases of PV B19-induced transient aplastic in different clinical settings--pancytopenia in one child, during induction phase for acute lymphoblastic leukemia in the second, and fever with joint pains in the third. Treatment for PV B19-induced transient aplastic crisis is essentially supportive. There may be a dilemma in patients on immunosuppressive therapy, since initially it is difficult to distinguish between chronic pure red cell aplasia (a condition where intravenous immunoglobulin therapy is beneficial) and transient aplastic crisis, where supportive red cell transfusions suffice. The patient with leukemia also recovered spontaneously despite being on steroids. In all the 3 patients, the pure red cell aplasia recovered spontaneously without administration of intravenous gammaglobulins.
