Extracorporeal photoimmunotherapy (ECP) has been successfully used as adjunct treatment for steroid-resistant graft-versus-host disease (GvHD) after allogeneic stem cell transplantation. We serially investigated serum levels of soluble interleukin-2 receptor-alpha (sIL-2Ralpha), soluble tumor necrosis factor receptor I (sTNF-RI), and soluble CD8 (sCD8) in 19 patients with steroid-resistant acute GvHD before and after each ECP treatment. Highest levels of sIL-2Ralpha and sTNF-RI correlated with severe acute GvHD and infections. Despite an immediate sIL-2Ralpha and sTNF-RI decrease after each treatment cycle, a mean surge of sTNF-RI>sIL-2Ralpha during the first three ECP cycles was observed in infections. A delayed surge, i.e., after the third ECP cycle, of sIL-2Ralpha and elevated post-ECP sCD8 levels was observed in patients developing chronic GvHD. While levels of sIL-2Ralpha and sTNF-RI correlate with the severity of acute GvHD and infections during the early ECP treatment period, the recurring increase of post-ECP sCD8 possibly may serve as parameter for developing chronic GvHD.

Basiliximab, a chimeric interleukin-2 receptor (IL-2-R) antagonist, was evaluated in 17 patients with steroid-refractory acute graft-versus-host disease (GVHD) after allogeneic stem cell transplantation (SCT). Patients were transplanted from a related (n = 6) or unrelated (n = 11) HLA-identical donor because of acute lymphoblastic leukemia (n = 4), acute myeloid leukemia (n = 3), chronic myeloid leukemia (n = 7), myelodysplastic syndrome (n = 1), non-Hodgkin's lymphoma (n = 1), and multiple myeloma (n = 1). Basiliximab was given at a dose of 2 x 20 mg on 2 consecutive days after steroid-refractory acute GVHD had developed. Basiliximab was repeated on day 8 in cases of persistent GVHD. A median of four basiliximab infusions (range 1-12) were given to these patients. None had infusion-associated or cytokine-related side-effects after basiliximab. Twelve of 17 patients (71%) responded to basiliximab, 9/17 (53%) had a complete response (CR) of acute GVHD and 3/17 (18%) had a partial response (PR). Five of 17 patients (29%) did not respond. Chronic GVHD developed in 8/13 evaluable patients and only 2/8 had responded to basiliximab before. Five of 13 evaluable patients have no signs of chronic GVHD and all five had a CR or PR after basiliximab. This is the first report on the safety of basiliximab in patients with steroid-refractory acute GVHD. Our data suggest that basiliximab is effective in a substantial proportion of these patients.

Graft-versus-host disease (GVHD) after orthotopic liver transplantation (OLT) is a serious complication with mortality rates over 80%. Two patients with established GVHD after OLT were treated with Basiliximab, a chimeric murine human monoclonal antibody which binds to the alpha-chain of interleukin-2 receptor (IL-2R). Two males, aged 45 and 56 years, presented after OLT with a clinical picture consistent with GVHD. Quantitative measurements of recipient peripheral blood donor lymphocyte chimerism were carried out by flow cytometric analysis, and showed peak chimerism levels of 5% and 8%, respectively. Treatment comprised 3 doses of 1 g methyl prednisolone followed by 2 doses of 20 mg of Basiliximab. In both, treatment resulted in complete disappearance of macro-chimerism in blood. There was resolution of skin rash by day 7; however, diarrhea persisted. White cell scan showed increased uptake in the terminal ileum and small-bowel resection was performed in both patients. One patient is alive and well 36 months after OLT. The other patient had resolution of GVHD, but died of recurrent hepatitis C 1 year after OLT. The combination of immunological and surgical treatment for GVHD following solid organ transplantation has not previously been described.

Acute graft-versus-host disease (GVHD) may affect several organs. Syndecan-1 is a heparan sulfate proteoglycan that can be shed from the surface of most epithelial cells (skin, liver, and gut among others), which are target organs for GVHD. Syndecan-1 was measured in serum samples from 60 patients after allogeneic stem-cell transplantation and was related to the degree of GVHD. Syndecan-1 levels increased in patients who developed acute GVHD but not in patients without GVHD. The difference between groups was significant 3 to 10 weeks after transplantation. The peak level of syndecan-1 in serum correlated with the degree of acute GVHD (r=0.46, P<0.001). Combined, the peak levels of syndecan-1 and soluble interleukin-2 receptor detected patients with acute GVHD (sensitivity 82%, specificity 89%). This study shows that syndecan-1 levels are increased during acute GVHD. Syndecan-1 may be a marker for acute GVHD, especially if combined with determination of soluble interleukin-2 receptor.

Donor T cells activated by recipient alloantigens cause graft-versus-host disease (GVHD) after hematopoietic cell transplantation. Activated T cells express CD25, among other components of the interleukin-2 receptor. We conducted a phase I/II study to determine whether administration of CD25-specific antibody conjugated to ricin toxin A could reduce the risk of grade III or IV GVHD after marrow transplantation from HLA-matched unrelated donors. All patients received methotrexate and cyclosporine after the transplantation. The immunotoxin was given to 36 patients for 4 consecutive days beginning approximately 36 hours after the marrow infusion was completed. Fourteen (40%) of the 35 patients who could be evaluated developed grade III or IV GVHD. In a contemporaneous population of 121 patients who received marrow from HLA-matched unrelated donors and were given methotrexate and cyclosporine without the immunotoxin, the incidence of grades III and IV GVHD was 24%. Cyclosporine blocked the induction of CD25 expression on alloactivated T cells in vitro but had no detectable effect on CD25 expression by T-regulatory cells. Taken together, these results are consistent with the hypothesis that cyclosporine protected alloactivated donor T cells from the effects of the immunotoxin, whereas the CD25+ T-regulatory cells remained susceptible, causing an unexpected exacerbation of acute GVHD.

We report the case of 13-year-old boy who had been diagnosed as having anaplastic large cell lymphoma (ALCL) when he was 11 years old. He suffered a relapse despite the chemotherapy regimens he had been subjected to. Since anaplastic lymphoma kinase (ALK), one of the important prognostic factors of ALCL, was not expressed in the tumor cells, allogeneic peripheral blood stem cell transplantation (PBSCT) from his HLA-matched elder brother was performed. Eleven months after PBSCT, the patient developed nephrotic syndrome as a consequence of chronic graft-versus-host disease (GVHD). He was diagnosed as having membranous nephropathy (MN) based on the results of histological examinations. Soluble interleukin-2 receptor and anti-nuclear antibody closely reflected the clinical course of MN, therefore some immune mechanisms closely related to chronic GVHD seemed to contribute to the occurrence of MN after PBSCT.

Soluble interleukin-2 receptor (sIL-2R) levels were analyzed in 127 stem-cell transplant recipients. Granulocyte-colony stimulating factor (G-CSF) was given to 57 patients after transplantation. We found an association between G-CSF and increased sIL-2R levels. This indicates increased T-cell activation and may be one reason for the previously found increased incidence of acute graft-versus-host disease in G-CSF-treated patients.

Denileukin diftitox (DAB389IL-2; Ontak) is a novel recombinant fusion protein approved by the US Food and Drug Administration for the treatment of relapsed or refractory cutaneous T-cell lymphoma. It consists of fragments of diphtheria toxin linked to human interleukin-2 and works by targeting the high-affinity interleukin-2 receptor expressed on malignant cells. This article will review the clinical trials leading to the approval of denileukin diftitox for cutaneous T-cell lymphoma, and discuss the potential future role of this novel drug in patients with both malignant and nonmalignant diseases, including non-Hodgkin's lymphoma, chronic lymphocytic leukemia, solid tumors, psoriasis and graft-versus-host disease.

Inolimomab [corrected] an anti-interleukin-2 receptor (anti-IL-2R) monoclonal antibody, may be useful in the treatment of steroid-refractory acute graft-versus-host disease (aGVHD) by inhibiting 1 of its putative immunopathogenic pathways. We retrospectively analyzed 40 consecutive patients who received inolimomab [corrected] as salvage treatment for steroid refractory aGVHD at a single institution between June 1999 and December 2004. Inolimomab [corrected] was given intravenously at a dose of 11 mg/d for 3 consecutive days, followed by 5.5 mg/d for 7 consecutive days and then 5.5 mg every other day for 5 doses. No infusion-related side effects were noted. Twenty-three patients (58%) responded, including 15 (38%) complete and 8 (20%) partial responses. Median overall survival was 294 days (58-996 days) for responders versus 14 days for nonresponders (P < .001), with a 1 year probability of 59% vs 0% for overall survival (P < .0001). Patients without gastrointestinal (GI) involvement showed a higher response rate (100% versus 50% for those without versus with GI involvement, P = .03) In addition, patients who showed some response by day 15 had a higher overall survival (73 +/- 12% vs 24 +/- 12%, respectively, P = .02). The results of this study suggest that inolimomab [corrected] may be an effective salvage therapy for patients with steroid-refractory aGVHD, particularly for those without GI disease, and supports further studies with this agent in prospective controlled trials.
