Feasibility and response to budesonide as topical corticosteroid therapy for acute intestinal GVHD.

Therapy of acute intestinal GVHD is still one of the main challenges after allogeneic transplantation. Increasing systemic immunosuppression (IS) is the first choice and includes corticosteroids and lymphocyte antibodies, often associated with severe side-effects. In inflammatory bowel diseases such as Crohn's disease and ulcerative colitis, topical steroid therapy is used very successfully. Because of the similarity between these and acute intestinal GVHD we conducted a trial with oral budesonide (Budenofalk), a new topically active glucocorticoid, to treat patients with acute GVHD > or = grade II. After a diagnosis of aGVHD > or = grade II, 22 patients received increased IS, mainly systemic corticosteroids, and additionally budesonide 9 mg/day divided into three doses. Improvement in aGVHD, infectious side-effects, reduction of systemic IS and outcome were documented. Results were compared with the results of 19 control patients, who were treated only by increasing IS dose. In 17/22 patients (70%), treated with budesonide, the acute intestinal GVHD resolved and no relapse occurred after decreasing the systemic IS, while continuing budesonide. In only 8/19 patients in the control group did the acute intestinal GVHD resolve and 2/8 patients had a relapse of intestinal GVHD after decreasing IS, with an overall response of 33%. No severe intestinal infections occurred. We conclude that budesonide may be effective in acute intestinal GVHD as a topical corticosteroid and prospective, randomized studies should demonstrate its efficacy in allowing reduction of systemic immunosuppressive therapy, and its side-effects.

Expansion and fibronectin-enhanced retroviral transduction of primary human T lymphocytes for adoptive immunotherapy.

Human lymphocytes remain among the most promising target cells for gene therapy. Gene-modified lymphocytes have been used successfully to treat adenosine deaminase (ADA)-deficient patients and to control GvHD after allogeneic BMT. Because activation and proliferation of T cells are necessary for efficient retrovirus-mediated gene transfer and subsequent selection of transduced cells, mononuclear cells (MNC) from steady-state and G-CSF-stimulated peripheral blood were activated by short exposure to the mitogen PHA, the anti-CD3 antibody OKT3, or both in the presence of different concentrations of recombinant IL-2. Using OKT3 (10 or 30 ng/ml) and IL-2 (100 U/ml), T cells expanded efficiently during a 14-day culture period. Cell expansion was similar under serum-free conditions. The immunophenotypic profile over time showed a marked increase in CD8+ cells, leading to a reversed CD4/CD8 ratio of 1:2 and a slight increase in CD56+ cells. Supernatant-based centrifugal transduction of primary human T lymphocytes was compared with supernatant transduction on the extracellular matrix protein fibronectin. Transduction with cell-free retrovirus-containing supernatant in tissue culture flasks coated with human plasma fibronectin led to significantly higher transduction efficiencies (20% +/- 7.5%) than centrifugal transduction in uncoated culture flasks (13.6% +/- 5.1%)(p = 0.041). To both rapidly characterize transduced cells and isolate these from residual nontransduced but biologically equivalent cells, an amphotropic Moloney murine leukemia virus (MoMuLV)-based retroviral vector containing the intracytoplasmically truncated human low-affinity nerve growth factor receptor (deltaLNGFR) cDNA as a marker gene was used. FACS sorting of T cells after transduction resulted in >90% LNGFR+ cells and was much faster than enrichment of transduced cells through growth in G418-selection medium. These results show that supernatant-based retroviral gene transfer into primary human T lymphocytes can be enhanced by fibronectin. Ectopic expression of a cell surface protein can be used to rapidly and conveniently quantitate transduction efficiency through FACS analysis and to efficiently enrich transduced cells through FACS sorting.

An open, randomized, multicentre study comparing the use of low-dose ceftazidime or cefotaxime, both in combination with netilmicin, in febrile neutropenic patients. German Multicentre Study Group.

To reduce drug acquisition costs, the clinical and bacteriological efficacy of low-dose ceftazidime i.v. (1 g tid) was compared with cefotaxime i.v. (2 g tid). Both regimens were combined with netilmicin i.v. (2 mg/kg bodyweight tid), in an open, randomized, multicentre trial in febrile neutropenic patients. The addition of antibiotics for gram-positive coverage was part of the protocol; alteration in the antibiotics for gram-negative cover or premature discontinuation of the study antibiotics were judged as failure. One hundred and eighty six patients were randomized by nine German centres, the patients matched for age, underlying diseases and duration of neutropenia (median duration 14 days) in both treatment arms. Infections were documented microbiologically in 29% of the patients, clinically in 16% and suspected (fever of unknown origin) in 102/186 patients (55%). The 82 pathogens isolated were predominantly gram-positive bacteria. In an intent-to-treat analysis, the overall response rate without modification at the final evaluation was 58% in the ceftazidime group and 34% in the cefotaxime group (P < 0.01). The success rates with modification were 84% and 64%, respectively. The failure rate in a highly immunosuppressed subgroup of the patients (bone marrow transplant recipients) was higher for cefotaxime (53%) than for the ceftazidime arm (14%) (P < 0.001). Response rates were significantly higher in the ceftazidime group for patients with microbiologically documented and possible infections. No major bacterial superinfections occurred in the low-dose treatment arm. The tolerability was good for both regimens. Low-dose ceftazidime combined with netilmicin proved to be superior to recommended doses of cefotaxime/netilmicin in febrile neutropenic patients.

High-versus standard-dose filgrastim (rhG-CSF) for mobilization of peripheral-blood progenitor cells from allogeneic donors and CD34(+) immunoselection.

PURPOSE: The efficacy of a high- versus a standard-dose filgrastim (recombinant human granulocyte colony-stimulating factor, or rhG-CSF) regimen to mobilize peripheral-blood progenitor cells (PBPCs) for allogeneic transplantation was investigated in 75 healthy donors. PATIENTS AND METHODS: From December 1994 to December 1997, 75 consecutive donors (median age, 38 years; range, 17 to 67 years) were assigned to two different schedules of rhG-CSF for PBPC mobilization. Fifty donors received 24 microg rhG-CSF/kg body weight (BW) divided into two daily subcutaneous injections (two doses of 12 microg, group A), whereas 25 were treated with 10 microg rhG-CSF once daily (group B). Apheresis was started on day 4 in group A and on day 5 in group B. Target CD34(+) cell numbers in apheresis products were >/= 4 x 10(6)/kg recipient BW. RESULTS: Cytokine priming and collection of PBPCs were equally well tolerated in both groups. Significantly higher CD34(+) cell numbers in group A with 3. 7 x 10(6)/kg recipient BW/apheresis (0.47 x 10(6)/L apheresis) compared with 2 x 10(6)/kg recipient BW/apheresis (0.25 x 10(6)/L apharesis) in group B were obtained (P <.05). Using standard aphereses (median, 9 L), two doses of 12 microg rhG-CSF/kg allowed collection of >/= 4 x 10(6)/kg CD34(+) cells with two aphereses (range, one to three) in group A versus three aphereses (range, one to six) in group B (P <.015). Donor age, sex, and BW influenced the collection of CD34(+) cell numbers: in particular, significantly higher apheresis results were obtained in donors younger than 40 years compared with donors older than 40 years of age (P <.05). In 65 CD34(+) selection procedures using avidin-biotin immunoabsorption columns (Ceprate SC System, CellPro, Bothell, WA), a median CD34(+) purity of 53%, CD34(+) recovery of 40%, and the collection of 2 x 10(6)/kg CD34(+) cells/selection were achieved. In group A with higher CD34(+) cells/kg/apheresis, CD34(+) purity, recovery, and cell yields were 60%, 45%, and 2.3 x 10(6)/kg/selection, respectively, as compared with 48%, 31%, and 0.7 x 10(6)/kg in group B (P <.05). CONCLUSION: Our results demonstrate that twice daily rhG-CSF (two doses of 12 microg/kg BM) compared with once daily rhG-CSF (10 microg/kg BW), in addition to being well tolerated, significantly improves PBPC mobilization, allows the collection of higher numbers of CD34(+) cells with one or two standard aphereses, and facilitates subsequent selection procedures in healthy allogeneic donors.

Interferon-gamma and CXC chemokine induction by interleukin 12 in renal cell carcinoma.

Interleukin 12 (IL-12) is known to play an important role in the development of an antitumor response. Its activity has been shown to be dependent upon the intermediate production of IFN-gamma and the influx into the tumor of CD8 lymphocytes. In a murine model, tumor regression induced by IL-12 treatment correlated with IFN-gamma, IP-10, and Mig expression in the tumor bed and was abrogated by antibodies to both chemokines. Here we examined the effects of rHuIL-12 on IFN-gamma and CXC chemokine gene expression in patients with renal cell carcinoma (RCC) in an attempt to determine whether a similar series of molecular events leading to IL-12-mediated tumor regression in mice is also detectable in humans. As in the murine RENCA model, cultured RCC cells themselves could be induced by IFN-gamma to synthesize IP-10 and Mig mRNA. Explanted RCC produced IFN-gamma and IP-10 mRNA in response to IL-12 treatment, which was consistent with the finding that biopsied RCC tumors from IL-12-treated patients also variably expressed augmented levels of those molecules after therapy. Although Mig mRNA was present in the majority of biopsied tumors prior to treatment, both the Mig and IP-10 chemokines as well as IFN-gamma were induced in the peripheral blood mononuclear cells of IL-12-treated patients. Skin biopsies of IL-12-treated patients also all synthesized IP-10 mRNA. This study demonstrates that recombinant human IL-12 therapy of patients with RCC has the potential to induce the expression of gene products within the tumor bed that may contribute to the development of a successful antitumor response.

Constitutive expression of the Wilms tumor suppressor gene (WT1) in renal cell carcinoma.

The expression of the Wilms tumor suppressor gene WT1 is largely restricted to elements of the developing urogenital system. In the fetal kidney, WT1 transcripts are present at low levels in the condensing mesenchyme and at much higher levels in differentiating glomerular epithelium and are not detected in other mesenchymal-derived epithelial structures such as the proximal and distal tubules. However, WT1 expression is observed in tubule-like elements found in some Wilms tumors. As renal cell carcinoma (RCC) of the clear cell type is one of the most prevalent adult tumors of the kidney, and is thought to originate from the epithelial cells of the proximal tubules, we studied WT1 expression in RCCs. Despite the absence of WT1 in normal primary epithelial cells derived from proximal tubules, RCC tumors and tumor-derived cell lines expressed WT1 RNA. Immunocytochemical analyses of tumor cryosections showed widespread expression throughout the poorly differentiated epithelial components of the tumor. Immunoblots of RCC samples detected a normal size WT I protein and reciprocal antibody immunoprecipitations of RCC cell extracts indicated that WT I interacts with p53 as has been demonstrated for normal human fetal kidney. The aberrant expression of functional WT1 in RCC may represent a reversion to a more de-differentiated phenotype and may contribute to the tumorigenic phenotype by inappropriately activating or repressing genes involved in growth regulation.

Impaired activation of NFkappaB in T cells from a subset of renal cell carcinoma patients is mediated by inhibition of phosphorylation and degradation of the inhibitor, IkappaBalpha.

Activation of the transcription factor NFkappaB in peripheral blood T cells from patients with renal cell carcinoma (RCC) is compromised. This impaired signaling function results from a failure of RelA and c-Rel to translocate to the nucleus though normal levels of Rel proteins are present in the cytoplasm. We demonstrate here in a subset of RCC patients that the defect in NFkappaB activation is attributable to the absence of phosphorylation and degradation of the inhibitor IkappaBalpha. In patient T cells there was no stimulus dependent decrease in the cytoplasmic level of IkappaBalpha. Coimmunoprecipitation studies showed that RelA was in complex with IkappaBalpha and was not released after stimulation. Moreover, the phosphorylated form of IkappaBalpha detected in normal T cells after activation is absent in patient T cells. Additional experiments showed that soluble products from RCCs (RCC-S) can reproduce the same phenotype in T cells from healthy individuals. Supernatant fluid from cultured explants of RCC, but not normal kidney, inhibited the stimulus dependent nuclear translocation of NFkappaB without altering the cytoplasmic levels of RelA, c-Rel, and NFkappaB1. Phosphorylation and degradation of IkappaBalpha was also blocked by RCC-S. The mechanistic similarities between patient-derived T cells and normal T cells cultured with RCC-S suggest that the tumor-derived products may be the primary mediators of impaired T-cell function in this tumor system.

Sinus venous thrombosis: an unusual cause for neurologic symptoms after bone marrow transplantation under immunosuppression.

BACKGROUND: Hematopoietic and organ transplantations are increasing worldwide with more patients receiving immunosuppressive therapy. Neurological problems may complicate the posttransplant period. Possible causes include the conditioning regimen (e.g., seizures with busulfan), central nervous system infections (viral, bacterial, and fungal), or factors secondary to the immunosuppressive therapy and side effects of drug treatment (e.g., cyclosporine and tacrolimus). Sinus venous thrombosis, the occlusion of a cerebral venous vessel or a sinus, is an unusual cause of neurologic symptoms in patients after transplantation, and this has not been reported in the literature previously. METHODS: Three patients presenting with various neurological symptoms after allogeneic bone marrow transplantation underwent computed tomography scans and magnetic resonance imaging as a primary diagnostic procedure. RESULTS: In all patients, sinus venous thrombosis was found as the cause for seizures; it was the cause of disturbance of consciousness in two patients and headaches in two patients. All symptoms resolved without any neurologic deficiency after anticoagulation therapy with heparin followed by dicumarol. CONCLUSION: We conclude that sinus venous thrombosis should be considered as a cause of neurological symptoms in patients after transplantation under immunosuppressive therapy. Diagnosis is rapidly confirmed by noninvasive magnetic resonance imaging angiography. Therapeutic heparinization is the treatment of choice.

Efficient serum-free retroviral gene transfer into primitive human hematopoietic progenitor cells by a defined, high-titer, nonconcentrated vector-containing medium.

Defined serum-free conditions have great conceptual advantages for the biological safety and standardization of clinical gene transfer into hematopoietic stem cells. In the only study reported to date, Sekhar et al. achieved low serum conditions by a complex concentration procedure of a retroviral supernatant initially containing 10% fetal bovine serum. The high cost, small volume, possible coenrichment of serum-derived pathogens, limited recovery of vector particles, and low titer of the final diluted medium restrict the clinical application of this procedure. Transduction of primitive hematopoietic progenitor cells was not demonstrated. In the present study, a defined serum-free medium containing high titers of the pseudotyped retroviral vector PG13/LN was generated from PG13/LN producer cells without requiring a physical enrichment procedure. The transduction of committed hematopoietic progenitor cells in the serum-free vector-containing medium was efficient, and similar to that occurring under serum-containing control conditions. The number of primitive human hematopoietic long-term culture-initiating cell-derived colonies (LTC-IC-derived colonies) generated from CD34+ and CD34+/HLA-DRlo peripheral blood progenitor "stem" cells (PBSCs) increased during 7 days of treatment in this vector-containing medium in the presence of IL-3, SCF, and flt-3 ligand. The described procedure allowed efficient transduction of LTC-IC-derived colonies generated from CD34+, CD34+/HLA-DRlo, and CD34+/CD38lo PBSCs. This is the first report to demonstrate an increase in primitive peripheral blood LTC-IC-derived colonies in vitro as well as their efficient transduction in a high-titer, serum-free vector-containing medium that can be produced exclusively from defined pharmaceutical-grade components, making it ideally suited for applications in clinical gene therapy.

Ex vivo activation of tumor-draining lymph node T cells reverses defects in signal transduction molecules.

The adoptive transfer of tumor-draining lymph node (LN) T cells activated ex vivo with anti-CD3 and interleukin 2 (IL-2) mediates the regression of the poorly immunogenic murine melanoma D5. The efficacy of the activated LN cells is augmented when the sensitizing tumor is a genetically modified variant (designated D5G6) that secretes granulocyte/macrophage-colony-stimulating factor. In contrast to anti-CD3/IL-2-activated LN cells, adoptive transfer of freshly isolated tumor-draining LN T cells has no therapeutic activity. To determine whether the acquisition of antitumor function during ex vivo activation is associated with modifications in signal transduction capacity, the protein tyrosine kinases p56lck and p59fyn and proteins of the NF-kappaB family were analyzed in tumor-draining LN T cells. The levels of p56lck and p59fyn were lower in tumor-draining than in normal LN T cells and production of tyrosine-phosphorylated substrates was markedly depressed following anti-CD3 stimulation. After 5-day anti-CD3/IL-2 activation, levels of p56lck and p59fyn and protein tyrosine kinase activity increased. Interestingly, the levels of p56lck, p59fyn, and tyrosine kinase activity were higher in activated T cells derived from LN that drained D5G6 than they were in those from D5 tumors. In contrast, the cytoplasmic levels of c-Rel and Rel A were normal in freshly isolated tumor-draining LN, as was nuclear kappaB DNA-binding activity induced by anti-CD3 mAb or phorbol myristate acetate. Stimulation of activated LN cells with D5 tumor cells induced the nuclear translocation of NF-kappaB. These findings indicate that the recovery of proteins mediating signal transduction through the T cell receptor/CD3 complex in LN T cells activated ex vivo was associated with the acquisition of antitumor function.

Successful adoptive immunotherapy for relapse of AML 9 years after T-cell-depleted BMT.

Relapse is one of the main problems which can occur following allogeneic transplantation for haematological malignancies. In this situation the enhancement of the graft-versus-leukaemia effect by transfusion of donor buffy coats with or without cytokines may lead to complete remission especially in myeloid leukaemias. FISH (fluorescence in situ hybridization) is a sensitive method to monitor chimaerism in gender-different transplantation. We report a case of successful buffy coat transfer therapy > 9 years after bone marrow transplantation. This is the longest interval reported, to our knowledge, between transplantation to relapse, which was treated by adoptive immunotherapy. Complete donor chimaerism was confirmed by FISH.

The JAK-STAT pathway: signal transduction involved in proliferation, differentiation and transformation.

STAT proteins become activated upon tyrosine and serine phosphorylation, are subsequently translocated from the cytosol to the nucleus where they exert DNA-binding activity. Several STAT binding consensus motifs have been identified in the promoters of distinct genes. These consensus elements mediate STAT recruitment and influence the kind of STAT proteins that are bound at a specific promoter site. Recent structure function analyses have revealed conserved amino terminal sequences to be crucial for phosphatase dependent deactivation of the STAT proteins. To date an increasing amount of data is available concerning the on- and off-regulation of STAT activity. Considerable convergence as well as crosstalk has been shown between the JAK-STAT pathway and the MAPK, RAS, PI3K, PKC, and PKA involving pathways. Moreover, the nature of the genes that are regulated by STAT proteins as well as the cell functions that result from STAT activation are of great current interest. Understanding the critical functional role of STAT mediated signalling events as well as their regulation by interfering pathways provides new insights into the mechanisms involved in malignant cell proliferation.

[Effects of inpatient client-centered psychotherapy in various illness: 1-year follow-up].

The long-term effect (1-year-follow-up) of an inpatient client-centred psychotherapy programme was evaluated in 202 severe and chronically disturbed patients with a bread diagnose range (ICD-10 F1-F6). These 202 patients represented 74% of a total of 272 patients who had originally been examined and tested at admission and had now been re-identified after a follow-up of one year. Patients were investigated via Clinical Global Impressions (CGI), Bech-Rafaelsen-Melancholia-Scale (BRMES) and the Personality Inventory (Giessen-Test). Severity of illness, depressivity and self-and-other acceptance improved significantly; social incompetence was especially reduced in patients who had personality disorders. The range of effects reached from good to very good improvement: the magnitude of effect on social variables is probably even under estimated due to high pre-therapy variance. At follow-up 68% of the patients were in occupation or professional education. 32% needed no further treatment. Readmission rate was 14%. Results are discussed with regard to specific client-centred therapy.

Tumor-induced suppression of T lymphocyte proliferation coincides with inhibition of Jak3 expression and IL-2 receptor signaling: role of soluble products from human renal cell carcinomas.

The proliferative capacity of T cells infiltrating human tumors is known to be impaired, possibly through their interaction with tumor. Here we demonstrate that soluble products derived from renal cell carcinoma (RCC-S) explants but not normal kidney can inhibit an IL-2-dependent signaling pathway that is critical to T cell proliferation. A major target of the immunosuppression was the IL-2R-associated protein tyrosine kinase, Janus kinase 3 (Jak3). RCC-S suppressed basal expression of Jak3 and its increase following stimulation with anti-CD3/IL-2. Jak3 was most sensitive to suppression by RCC-S; however, reduction in expression of p56(lck), p59(fyn), and ZAP-70 was observed in some experiments. Expression of other signaling elements linked to the IL-2R (Jak1) and the TCR (TCR-zeta, CD3-epsilon, and phospholipase C-gamma) were minimally affected. In naive T cells, RCC-S also partially blocked induction of IL-2R alpha-, beta- and gamma-chain expression when stimulating via the TCR/CD3 complex with anti-CD3 Ab. To determine whether RCC-S suppressed IL-2-dependent signaling, primed T cells were employed since RCC-S had no effect on IL-2R expression but did down-regulate Jak3 expression and, to a lesser degree, p56(lck) and p59(fyn). Reduction in Jak3 correlated with impaired IL-2-dependent proliferation and signal transduction. This included loss of Jak1 kinase tyrosine phosphorylation and no induction of the proto-oncogene, c-Myc. These findings suggest that soluble products from tumors may suppress T cell proliferation through a mechanism that involves down-regulation of Jak3 expression and inhibition of IL-2-dependent signaling pathways.

Analysis of a regulatory element in the 5'-untranslated region of the bcl-2 gene.

The bcl-2 gene is an important antagonist of apoptosis, the programmed cell death. Bcl-2 is highly expressed in a variety of lymphomas. Lymphocytes of patients with chronic lymphocytic leukemia (CLL) express high amounts of bcl-2 even in the absence of the t(14;18) translocation, resulting in a strong resistance towards corticosteroid induced apoptosis. Within the 5'-untranslated region of the bcl-2 gene a p53 dependent negative response element has been described. Genetic alterations within this element could lead to uncontrolled overexpression of bcl-2 and subsequent resistance towards apoptosis. We therefore analyzed the mRNA from the 5'-untranslated region -279 to -85 bp of the bcl-2 gene by direct PCR sequencing from peripheral blood derived lymphocytes from patients with CLL and normal healthy donors. Compared to published sequences (Tsujimoto and Croce (1986) Proc. Natl. Acad. Sci. USA 83, 5214), we consistently found an exchange at position 1271 from A to G and at position 1284 from G to A in all CLL as well as normal donor derived samples analyzed. Thus, CLL specific alterations compared to normal cells could not be found and deregulated expression of bcl-2 in CLL cells does not appear to be due to alterations in the p53 dependent negative response element of the bcl-2 gene. However, our data add information to published sequence data of this region.

Early-onset secondary malignancies after high-dose chemotherapy and autologous hematopoietic stem cell transplantation.

We treated 500 patients with high-dose chemotherapy (HDC) and autologous bone marrow (ABMT) or autologous peripheral blood stem cell transplantation (PBSCT). Treated conditions included leukemia, lymphomas, breast cancer, lung cancer, germ-cell carcinomas, and other solid tumors. In order to assess relapse of primary malignancy or occurrence of new neoplasms, routine screening after ABMT or PBPCT was performed at regular and close intervals. With a total follow-up of 1358 person-years and a median follow-up of 34 months (range 9-91), 10/500 (2%) patients developed second malignancies after PBSCT or ABMT; i.e., one new cancer occurred every 136 person-years. All malignancies were detected at routine follow-up examinations; and 7/10 diagnoses were made in an asymptomatic phase; 6/10 neoplasms were amenable to complete surgical resection, five of which remain in CR at a median of 23+ months after autotransplantation. We conclude that regular and close follow-up examination of patients after autologous hematopoietic stem cell transplantation may be beneficial, since successful treatment of second malignancies is possible in selected cases after early detection.
