1/105. Fulminant adenovirus hepatitis following unrelated bone marrow transplantation: failure of intravenous ribavirin therapy.

    Fulminant hepatic failure due to adenovirus infection is a rare complication following stem cell transplantation. We report this complication in an unrelated bone marrow transplant recipient 30 weeks post-transplant. Treatment with intravenous ribavirin was started within 36 h of admission, but he succumbed to unusually fulminant hepatic failure. Adenovirus type 2 was isolated from stool surveillance samples and from post-mortem liver samples. Adenovirus dna was detected by PCR in blood and sputum samples at admission and was identified in post-mortem liver tissue by electron microscopy. Implications of the failure of ribavirin therapy are discussed.

2/105. Fulminant hepatic failure caused by adenovirus infection following bone marrow transplantation for Hodgkin's disease.

    Adenoviruses are increasingly realised to be responsible for serious morbidity and mortality following allogeneic bone marrow transplantation. We describe a case of fulminant hepatic failure due to adenovirus serotype 2 in a 39-year-old woman who received a matched sibling allogeneic bone marrow transplant for multiply relapsed Hodgkin's disease. Isolated fulminant hepatic failure caused by this serotype of adenovirus has not previously been described.

3/105. Haemorrhagic cystitis associated with adenovirus in a patient with AIDS treated for a non-Hodgkin's lymphoma.

    Adenovirus-induced haemorrhagic cystitis has been reported chiefly in bone marrow or kidney transplant recipients. We report here on an hiv-positive patient treated for a Burkitt's lymphoma who developed gross haematuria associated with fever and burning urination. Usual causes of haematuria were ruled out: lithiasis, urinary tract lesions, glomerulonephritis, mycobacterium and schistosoma infections, and drug toxicity. Adenovirus was detected by cellular cultures and BK/jc virus dna sequences were detected using a polymerase chain reaction method. Because BK/JC virus shedding is very common (75%) in hiv patients receiving chemotherapy, our data strongly suggest that adenovirus was responsible for the haemorrhagic cystitis in our patient. In conclusion, adenovirus should be considered as a potential cause of haemorrhagic cystitis in AIDS patients whose immunosuppression is aggravated by cytotoxic drugs.

4/105. Adenovirus infections following haematopoietic cell transplantation: is there a role for adoptive immunotherapy?

    Adenovirus has been recognised as an important pathogen in BMT recipients, especially in patients with GVHD and those receiving T cell-depleted allografts. We report adenovirus infections from an ongoing surveillance study in four patients after a non-myeloablative transplant and their improved outcome following withdrawal of immunosuppression in two patients and donor lymphocyte infusion for relapsed disease in the others. We discuss the control of adenovirus infections following immune manipulations and the feasibility of adoptive immunotherapy for post-transplant adenovirus infections.

5/105. Adenovirus and non-gonococcal urethritis.

    Non-gonococcal urethritis (NGU) is a common problem presenting to sexual health clinics that is usually managed empirically. In many cases the aetiology is never clearly established or further investigated. Adenovirus has been identified in the past as an occasional cause of NGU but little has been written about its clinical presentation. We present a case report of 6 men who were diagnosed with NGU caused by adenovirus infection, along with a review of the relevant literature, with the aim of improving clinical recognition of this pathogen.

6/105. Transplantation of CD34-enriched peripheral stem cells from an HLA-haplotype mismatched donor to a patient with severe aplastic anemia.

    A 14-year-old girl developed very severe aplastic anemia unresponsive to steroids, cyclosporine, ATG and filgrastim. She experienced repeated bacterial infections, hypermenorrhagia and epistaxis and received numerous transfusions. Lacking a matched family or unrelated donor, she was transplanted 6 months after diagnosis with CD34 cell-enriched peripheral stem cells from her HLA-haploidentical uncle. Conditioning included fludarabine, cyclophosphamide, 800 cGy TLI and OKT3. Prompt and sustained trilineage engraftment occurred. Acute GVHD grade 1 and herpes esophagitis were successfully treated. Eight months after grafting she was well with stable hematopoiesis. She then succumbed to fulminant hepatic failure due to adenovirus infection.

7/105. Fatal disseminated adenoviral infection in a renal transplant patient.

    Immunosuppressed patients are more susceptible to adenoviral infection and carry a significantly higher mortality than immunocompetent patients. Renal transplant patients with adenoviral infection most often present with infection of the kidney and urinary tract within weeks to months of transplant surgery, suggesting reactivation of the latent adenovirus in the immunosuppressed host as the source of infection. We describe the first case of a fatal adenovirus infection after several years of immunosuppression in a kidney transplant patient. Postmortem examination of several tissues, using standard viral culture and polymerase chain reaction, was positive for adenovirus serotype 21. This case is unusual in that the fatal disseminated viral infection occurred after 6 years of immunosuppression, suggesting that the source of adenovirus was a novel infection rather than reactivation of latent infection, or infection from the transplanted tissue. Furthermore, this is the first report of adenovirus type 21 in an immunosuppressed patient.

8/105. Adenovirus type 3 viremia in an adult with toxic shock-like syndrome.

    Surveillance by the Unexplained Deaths and Critical Illnesses Project (UNEX) uncovered a novel presentation of adenovirus type 3 infection that satisfied the criteria for toxic shock-like syndrome in a 28-year-old immunocompetent man. Adenovirus may be a cause of toxic shock syndrome; surveillance systems such as UNEX may uncover additional causes of this and other clinically defined infectious syndromes.

9/105. Lethal adenovirus infection in a patient who had undergone nonmyeloablative stem cell transplantation.

    We present a case of adenovirus (ADV) infection in a patient who had undergone nonmyeloablative stem cell transplantation (NST). A 50-year-old man with chronic myelogenous leukemia in the second chronic phase underwent NST from an HLA 2-loci-mismatched sibling. ADV hemorrhagic cystitis developed and progressed to lethal pneumonia. ADV was isolated from urine, bronchoalveolar lavage fluid, and postmortem specimens of kidney and liver. Because there are few reports of lethal pneumonia associated with ADV in japan, we present the case and discuss the cause of and therapy for the infection.

10/105. Fatal disseminated adenoviral infection associated with thrombotic thrombocytopenic purpura after allogeneic bone marrow transplantation.

    Adenoviruses are increasingly recognized as a significant cause of morbidity and mortality in immunocompromised patients. We report on a patient who, approximately 4 weeks after allogeneic stem cell transplantation, developed fever, new liver lesions and thrombotic microangiopathy. Adenovirus type 2 was isolated from blood and urine samples. liver biopsy showed parenchymal necrosis with intranuclear viral inclusion bodies. immunohistochemistry was positive for adenovirus. In addition, on electron microscopy the morphologic pattern was highly suggestive of adenovirus. The patient died on post-transplant day 40. The relatively early post-transplant presentation of disseminated adenoviral disease and its possible association with a TTP-like picture are rather unusual after allogeneic transplantation.
