The incidence of malnutrition and immunocompetence in 156 patients admitted to hospital with liver disease was investigated. Expected weight/height was within the normal range for all groups except those with carcinoma. Triceps skinfold thickness (TSF) was reduced in 49% of patients with cirrhosis and 55% with alcoholic disease. Hypoalbuminaemia was common in all groups, with 66% of those with chronic disease having concentrations below 35 g/dl. Lymphopenia was equally common, 65% of patients with fulminant hepatic failure (FHF) having counts below 1000 cells/mm3. Incidence of total anergy to standard skin tests was 54% overall: 93% in FHF and 60% in cirrhosis and alcoholic disease. There were significant links between reduced TSF and hypoalbuminaemia, lymphopenia and anergy, hypoalbuminaemia and anergy, and anergy and mortality. Reduced TSF was only associated with anergy in patients with chronic disease. The high incidence of immuno-incompetence may underlie the frequent occurrence of spontaneous infections in patients with liver disease, and the association between anergy and malnutrition in patients with chronic liver disease suggests that the anergy may be partly reversible by dietary measures.

According to several histological and immunological features undifferentiated carcinoma of the nasopharynx (UCNT) is different from other ORL carcinomas (abundant lymphocytic infiltrate and frequent positive serology to EBV). Thus, immunological and virusological investigations were frequently performed in order to determine their diagnostic and prognostic significance. This study mainly concerned EBV serology and related immunological parameters. There are less data about immunological profile in those patients. In the present study, several standard immunological parameters were tested (number of different rosette-forming cells in peripheral blood, immunoglobulins serum levels and blastic transformation in the presence of PHA) in 17 patients with UCNT, 16 males and 1 female, aged 20 to 79 years. The aim of this study was to find out whether these patients were different from healthy controls, and if any of these parameters could be of prognostic value. Results point to the following disturbances in our group of patients: absolute lymphopenia caused by T-lymphopenia and significant decrease in ability of blastic transformation. Contrary to the registered suppression of cellular immunity there was a certain degree of stimulation of humoral response detected by hypergamaglobulinaemia and appearance of monoclonal immunoglobulin components in sera of few patients. All these immunological disturbances have no prognostic value in predicting the treatment response to chemotherapy.

We have reported a 27% overall anti-tumor response using i.p. immunotherapy of advanced ovarian carcinoma with autologous, ex vivo expanded, T lymphocytes re-targeted with bi-specific monoclonal antibody OC/TR, combined with soluble OC/TR and low-dose recombinant interleukin-2 (IL-2). This treatment had no effect on extraperitoneal disease. Therefore we studied in 13 patients whether this immunotherapeutic protocol resulted only in local or also in systemic immunomodulation. The phenotype of the ex vivo expanded lymphocytes was mainly CD3+, 4-, 8+, 16-, 56-. Their OC/TR-re-targeted cytolytic activity against Igrov-1 ovarian-carcinoma cells was approximately as high in responders as in non-responders. Following most therapeutic cycles, the immunophenotype of lymphocytes recovered from the peritoneal fluid was similar to that of the infused T cells (i.e., mainly CD3+, 4-, 8+) and they were coated with OC/TR. However, cytolytic activity of the recovered lymphocytes against Igrov- 1 cells was low in direct assays, and only slightly increased after additional in vitro re-targeting with OC/TR. Systemically, the i.p. immunotherapy resulted in a transient lymphopenia lasting for about 7 days, low (i.e., 5 to 13 ng/ml) serum concentrations of free, functional OC/TR, and very weak coating of circulating T lymphocytes with OC/TR. These peripheral-blood T lymphocytes did not exert OC/TR-re-targeted cytolytic activity. Thus, locoregional OC/TR-re-targeted cellular immunotherapy resulted in substantial local immunomodulation and anti-tumor effects but virtually no systemic immunomodulation.

Petroleum ether extract from H. spinosa root exhibited antitumor activity in Ehrlich ascites carcinoma and Sarcoma-180 bearing mice Processed extract suppressed significantly the tumor fluid volume at the end of 3 weeks experiment. It decreased about 50% of packed cell volume and increased life span of EAC/S-180 bearing mice in a day dependent manner. Red blood cell count, hemoglobin content and white blood cell count were more or less normal after processed extract treatment of the tumor bearing mice. In tumor control animals, neutrophils increased (273.7% in EAC and 263.4% in S-180 bearing mice respectively with respect to normal mice) whereas lymphocytes decreased (60.0% in EAC and 56.5% in S-180 bearing mice respectively with respect to normal mice). It also inhibited the rapid increase of body weight of tumor bearing mice.

Between March 1992 and August 1993, thirty patients with hairy cell leukemia (HCL) were treated in a single institution with 2-chlorodeoxyadenosine (2-CdA) for one course (N=27) or two courses at six month interval (N=3). Sixteen patients were previously untreated, 14 had been treated with alpha interferon (alpha IFN) (N=5), alpha IFN and splenectomy (N=8) and splenectomy, alpha IFN and Deoxycoformycin (N=1). Overall results in 29 evaluable patients were: 25 CR (86%), 3 PR (10%), one failure. The three PR patients relapsed after 18, 24 months and five years. Two were retreated successfully. Two CR patients relapsed after five years. Careful clinical survey, sequential bone marrow biopsies (BMB) with DBA44 immunostaining for assessment of response and detection of residual disease and serially evaluation of lymphocyte subsets counts were performed. Results of bone marrow biopsies study show 1) a progressive reduction in hairy cell infiltration during the first six months after therapy and not after that indicating that the best moment for the evaluation of response may be the sixth month, 2) the persistence of a very small number of DBA44+ cells (80% of BMB). There was a correlation between the presence of > 5% DBA44 positive cells on 6th month BMB and relapse. 60% had an absolute CD4+ lymphocyte count less than 0.2 10(9)/l at least on one examination after treatment. CD4+ lymphocyte level persisted less than baseline level in 8/18 patients tested after four and/or five years. Lymphopenia was less marked in splenectomized patients: 7/7 splenectomized patients tested have recovered a CD4+ lymphocyte count equal to pretherapy level compared to 3/11 non splenectomized patients (p: 0.004). Three opportunistic infections were observed early (first 6 months) after 2CdA therapy: pneumocystis pneumonia, retinitis due to toxoplasma in the patient who failed and legionella pneumonia in a patient retreated after relapse. Two patients developed a second carcinoma 6 and 12 months after therapy. Five patients died, three from a cause unrelated to HCL, one from HCL and one from infection while in second CR. At five years, overall survival is 83% and progression free survival is 66%. Our study shows 1) long-lasting response in the majority of patients after 2-CdA, 2) a correlation between persistent minimal residual disease detected with DBA44 immunostaining and occurrence of relapse and 3) a profound and persistent CD4+ lymphopenia more marked in non splenectomized patients.

Bispecific antibody (BsMAb) BIS-1 has been developed to redirect the cytolytic activity of cytotoxic T lymphocytes (CTL) to epithelial glycoprotein-2 (EGP-2) expressing tumour cells. Intravenous administration of BIS-1 F(ab')2 to carcinoma patients in a phase I/II clinical trial, caused immunomodulation as demonstrated by a rapid lymphopenia prior to a rise in plasma tumour necrosis factor-alpha and interferon-gamma levels. Yet, no lymphocyte accumulation in the tumour tissue and no anti-tumour effect could be observed. These data suggest a BsMAb-induced lymphocyte adhesion to blood vessel walls and/or generalized redistribution of the lymphocytes into tissues. In this study, we describe the effects of BIS-1 F(ab')2 binding to peripheral blood mononuclear cells (PBMC) on their capacity to interact with resting endothelial cells in vitro. Resting and pre-activated PBMC exhibited a significant increase in adhesive interaction with endothelial cells when preincubated with BIS-1 F(ab')2, followed by an increase in transendothelial migration (tem). Binding of BIS-1 F(ab')2 to PBMC affected the expression of a number of adhesion molecules involved in lymphocyte adhesion/migration. Furthermore, PBMC preincubated with BIS-1 F(ab')2 induced the expression of endothelial cell adhesion molecules E-selectin, VCAM-1 and ICAM-1 during adhesion/tem. These phenomena were related to the CD3 recognizing antibody fragment of the BsMAb and dependent on lymphocyte-endothelial cell contact. Possibly, in patients, the BIS-1 F(ab')2 infusion induced lymphopenia is a result of generalized activation of endothelial cells, leading to the formation of a temporary sink for lymphocytes. This process may distract the lymphocytes from homing to the tumour cells, and hence prevent the occurrence of BIS-1 F(ab')2 - CTL-mediated tumour cell lysis.

Diarrhoea, T-CD4+ lymphopenia and bilateral patchy pulmonary infiltrates developed in a male 60 yrs of age, who was treated with oxaliplatinum and 5-fluorouracil for unresectable rectum carcinoma. The findings from transbronchial lung biopsy and bronchoalveolar lavage (BAL) were consistent with an organizing diffuse alveolar damage pattern. Once extensive microbiological studies proved negative, corticosteroids were given and a complete remission of clinical and radiological abnormalities was achieved. It is concluded that the aforementioned pathological manifestations were due to chemotherapy and included a pulmonary adverse reaction, a feature never previously associated with oxaliplatinum and 5-fluorouracil regimens.

Kikuchi-Fujimoto disease (KFD), also know as histiocytic necrotizing lymphadenitis, is a benign disorder characterized histologically by necrotic foci surrounded by histiocytic aggregates, and with the absence of neutrophils. KFD was recognized in Japan, where it was first described in 1972. The disease is most commonly affecting young women. The cause of the disease is unknown, and its exact pathogenesis has not yet been clarified. Many investigators have postulated viral etiology of KFD, connecting it with Epstein Barr virus, human herpes simplex virus 6 parvo B 19, but also with toxoplasmic infection. Kikuchi-Fujimoto disease is usually manifested with lymphadenopathy and high fever, and is associated with lymphopenia, splenomegaly, and hepatomegaly with abnormal liver function tests, arthralgia, and weight loss. The disease has the tendency of spontaneous remission, with mean duration of three months. Single recurrent episodes of KFD have been reported with many years' pauses between the episodes. Kikuchi-Fujimoto disease may reflect systemic lupus erythematosus (SLE), and self-limited SLE-like conditions. Final diagnosis could only be established on the basis of typical morphological changes in the lymph node, and lymph node biopsy is needed for establishing the diagnosis. Lymphadenopathy in a patient with fever of the unknown origin could provide a clue to the diagnosis of lymphoma, tuberculosis, metastatic carcinoma, toxoplasmosis and infectious mononucleosis. As KFD does not have any classical clinical features and laboratory characteristics, it may lead to diagnostic confusion and erroneous treatment. We described a case of KFD, and suggested that this disease should be considered as a possible cause of fever of the unknown origin with lymphadenopathy.

3-Aminopyridine-2-carboxaldehyde thiosemicarbazone (3-AP, Triapine, Vion Pharmaceuticals, New Haven, CT) is an inhibitor of the M2 subunit of ribonucleotide reductase (RR). Preclinical testing demonstrates synergy between 3-AP and gemcitabine. Phase I studies of the combination have suggested tolerability and some initial evidence of efficacy. Therefore, a phase II study of gemcitabine plus 3-AP in advanced pancreatic carcinoma was undertaken. In this two-step phase II trial, patients with advanced pancreatic adenocarcinoma who had not received prior chemotherapy for advanced disease were treated with 3-AP 105 mg/m(2) given over 2 h. Four hours after the 3-AP infusion was completed, gemcitabine 1,000 mg/m(2) was given over 30 min. Both drugs were given on days 1, 8 and 15 of a 28-day cycle.Twenty-six patients were enrolled to the study. One patient withdrew consent prior to receiving any treatment and is excluded from all further analyses. Four patients discontinued treatment due to adverse effects. Grade 3/4 hematological adverse events included neutropenia, thrombocytopenia, lymphopenia, leukopenia and anemia and the most frequent non-hematological adverse events were fatigue and pain. No objective responses were observed. Eleven patients had stable disease (SD). In five of these eleven patients, SD lasted for more than 6 months. The median time to progression was 4.1 months and the 6 month progression-free survival rate was 29%. The median survival was 9.0 months with a 1-year survival of 28.0%. The combination of 3-AP and gemcitabine is associated with moderate toxicity in patients with advanced pancreatic cancer. This two-stage trial was stopped after stage I due to lack of antitumour activity. On the basis of this clinical trial, the combination of gemcitabine and 3-AP at this dose and schedule does not warrant further study in this patient population.

The objectives of this phase I study were to determine the maximum tolerated dose (MTD), recommended phase II dose (RD), antitumor activity, safety, and pharmacokinetics of pemetrexed-paclitaxel combination. Patients (N = 95) with advanced solid tumors were assigned to three schedules (21-day cycles [q21d]). Starting doses for each schedule of pemetrexed and paclitaxel, respectively, were: (S1) 400 and 135 mg/m(2) on d1; (S2) 400 mg/m(2) d1 and 40 mg/m(2) d1 and d8; S3) 400 mg/m(2) d8 and 30 mg/m(2) d1 and d8. MTD was 500/135 mg/m(2) (S1), 400/40 mg/m(2) (S2), and 500/120 mg/m(2) (S3). Most common dose limiting toxicities were febrile neutropenia, fatigue, and neuromotor toxicities. Most common toxicity was grade 3/4 lymphopenia. Four patients had partial response, 43 patients had stable disease. The RD determined was pemetrexed 500 mg/m(2) (d8) and paclitaxel 90 mg/m(2) (d1 and d8), q21d. The combination was well tolerated and showed efficacy in thyroid carcinoma and mesothelioma.
