          Abstract

          From January 1988 to January 1989 all the heart transplant and bone marrow recipients at the Instituto do Coração of the Hospital das Clínicas of the University of São Paulo Medical School were studied for the incidence and morbidity associated with herpesviruses infections after transplantation. Five bone marrow and 5 heart transplant recipients were followed for a mean of 4.2 months post-transplantation. All the patients were seropositive for cytomegalovirus (CMV) before admission and 80% experienced one or more recurrences during the observation period. Of the 12 episodes of CMV infection, that were identified in this study, 83% were accompanied by clinical or laboratory abnormalities. However, there was only one case of severe disease. The overall incidence of infection for herpes simplex (HSV) was 50%. Although most of HSV reactivations were oral or genital, one case of HSV hepatitis occurred. One of the 6 episodes of HSV infections that were treated with acyclovir showed an unsatisfactory response and was successfully managed with ganciclovir. All the individuals had anti-varicella zoster virus antibodies, but none of them developed infection. The study emphasizes the importance of active diagnostic surveillance of herpesvirus infections in transplant patients. Both CMV and HSV reactivations showed high incidence and important morbidity and thus, deserve prophylactic therapy.

          De janeiro de 1988 a janeiro de 1989 todos os pacientes submetidos a transplante de coração ou de medula óssea no Instituto do Coração do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo foram estudados quanto à incidência e morbidade das infecções pós-transplante causadas por vírus do grupo herpes. Cinco recipientes de medula óssea e 5 transplantados cardíacos foram observados por um período médio de 4.2 meses após o transplante. Todos os pacientes tinham sorologia positiva para citomegalovírus (CMV) antes do transplante e 80% desenvolveram uma ou mais recorrências durante o período de observação. Dos 12 episódios de infecão por CMV detectados neste estudo, 83% foram acompanhados por alterações clínicas ou laboratoriais. Apenas um caso apresentou doença grave. A incidência de infecções causadas por vírus Herpes simplex (HSV), foi de 50%. Apesar da maioria das reativações do HSV fossem representadas por lesões orais ou genitais, houve também um caso de hepatite por HSV. Um dos 6 episódios de infecção, por HSV que foram tratados com aciclovir não respondeu ao tratamento. Posteriormente, o paciente se beneficiou com o uso de ganciclovir. Todos os indivíduos apresentavam antes do transplante anticorpos anti-vírus da varicela zoster. Porém, não houve nenhum caso de reativação. Este estudo realça a importância do controle diagnóstico ativo das infecções por herpes-vírus em pacientes transplantados. Tanto as infecções causadas por CMV como por HSV mostraram alta incidência e grande morbidade indicando a necessidade de quimioprofilaxia.

          Intravenous immune globulin for prevention of cytomegalovirus infection and interstitial pneumonia after bone marrow transplantation.

          The effects of high doses of polyvalent intravenous immune globulin given for prophylaxis of cytomegalovirus infection and interstitial pneumonia in recipients of allogeneic marrow transplants were evaluated in a randomized controlled trial. Both symptomatic cytomegalovirus infection (21% compared with 46%, p = 0.03) and interstitial pneumonia (18% compared with 46%, p = 0.02) occurred less frequently in the recipients of intravenous immune globulin than in control patients. Prophylactic intravenous immune globulin was also associated with a lower incidence of graft-versus-host disease (34% in recipients compared with 65% in controls, p = 0.01), but its reduction in rates of interstitial pneumonia was independent of graft-versus-host disease and occurred in both patients with and without graft-versus-host disease. The high doses of immune globulin were well tolerated. Prophylactic intravenous immune globulin can modify the severity of cytomegalovirus infection and prevent interstitial pneumonia and possibly graft-versus-host disease in patients having allogeneic marrow transplantation.

              Prevention of cytomegalovirus infection by prophylaxis with an intravenous, hyperimmune, native, unmodified cytomegalovirus globulin. Randomized trial in bone marrow transplant recipients.

              We have completed a randomized trial to evaluate the safety and effectiveness of hyperimmune cytomegalovirus intravenous human globulin in prevention of cytomegalovirus infection and related problems in bone marrow transplant recipients. Prophylactic intravenous administration of this native, intact, hyperimmune, cytomegalovirus IgG, at a dose of 200 mg/kg 25, 50, and 75 days following transplant resulted in complete protection against cytomegalovirus infection during the 120 days covered by the treatment (p = 0.009). There was no interstitial pneumonia or mortality in the group receiving the hyperimmune IgG. This is significant at the p = 0.014 when compared with the supporting treatment control group. In bone marrow transplant recipients, prophylaxis with a total dosage of 0.6 g/kg of an intravenous hyperimmune cytomegalovirus globulin was safe and afforded effective protection against cytomegalovirus infection and interstitial pneumonia in this high-risk population.
