Presenting features and prognosis in 72 patients with multiple myeloma who were younger than 40 years

The purpose of this study was to analyse the presenting clinical and laboratory features and the outcome of 72 patients with multiple myeloma (MM) who were younger than 40 years. The records of all Mayo Clinic patients with MM younger than 40 years who were seen between 1 January 1956 and 31 December 1992 were reviewed. Survival was measured from the date when treatment was required to the date of last follow-up or death. The frequency of MM in patients younger than 40 and 30 years in 3278 Mayo Clinic patients was 2.2% and 0.3%, respectively. The main presenting clinical features were bone pain (66%), fatigue (26%), extramedullary plasmacytomas (19%) and bacterial infection (11%). Renal function impairment (creatinine level > or = 177 micromol/l) and hypercalcaemia (serum calcium value > or = 2.75 mmol/l) occurred in 29% and 30% of patients, respectively. Among the 57 patients evaluable for response the objective response rate was 54%. 14/35 patients treated with a single alkylating agent achieved an objective response, whereas 17/22 patients given combination chemotherapy had an objective response (P=0.013). However, this higher response rate did not result in a significantly longer survival. The median survival for the 72 patients was 54 months. Patients with good prognostic features (normal renal function or low beta 2-microglobulin level) had a median survival of 8 years. The actuarial survival at 5 and 10 years after initiation of therapy was 43% and 13%, respectively. In summary, survival in very young patients with myeloma is longer than that observed in series of patients of all ages, especially in those with good prognostic factors.     

Treatment of advanced colorectal cancer with folinic acid and 5-fluorouracil in combination with cisplatinum

51 patients with metastatic colorectal cancer (stage Dukes D) were treated with intravenous (i.v.) infusion on days 1, 3, 5, 8 and 16 with folinic acid (200 mg/m2) and 5-fluorouracil (600 mg/m2), and on days 1, 8 and 16 with cisplatinum (25 mg/m2 i.v.); cycles were repeated every 4 weeks. All 51 patients were evaluable for toxicity and response criteria. 26 patients had objective responses (3 complete responses, 5.9%; 23 partial responses, 45.1%), relative risk 51% (95% confidence intervals 36.7-65.0%). Response duration ranged from 4 to 28.0 months (median 16.8). Overall median survival of all patients included was 14.7 months (range 3.0-33.0). Toxicity of WHO grade III, requiring dose reduction, occurred in 9 (18%) patients. The regimen described here appears to be active, safe and well tolerated for treatment of patients with advanced colorectal cancer.     

Reactive arthritis in patients attending an urban sexually transmitted diseases clinic

OBJECTIVE: To assess the prevalence, clinical manifestations, associated genital infections, and HLA associations of reactive arthritis (ReA) among patients attending an urban sexually transmitted diseases (STD) clinic. METHODS: Using a standardized questionnaire, 271 consecutive adults, primarily black, with possible or proven Chlamydia trachomatis genital infection were screened for symptoms of ReA. A followup questionnaire was administered 6 weeks later by mail. Patients who reported at least 1 symptom were evaluated by a rheumatologist. HLA-B typing was performed on patients with objective ReA features. RESULTS: Nine of 217 patients (4.1%) with genital infection/inflammation had objective ReA features. Chlamydial or nongonococcal STD syndromes were diagnosed in 8 of these 9 patients (88%). Genital infection/inflammation was asymptomatic in 78% of patients with ReA features. HLA-B27 or other B7-cross-reactive group antigens were not associated with the occurrence of ReA. CONCLUSION: Nongonococcal genital infections, often asymptomatic, can trigger a relatively mild ReA in a larger number of exposed patients than previously thought, irrespective of the individual's HLA status.     

Palliative chemotherapy with CMF after the same adjuvant regimen for breast cancer. The Breast Cancer Study Group

BACKGROUND: The results of palliative chemotherapy with cyclophosphamide, methotrexate and 5-fluorouracil (CMF) in patients with advanced breast cancer who received adjuvant therapy with the same regimen were investigated. RESULTS: Of 47 patients, 14 (30%) achieved an objective remission (median duration 9.5, range 5-21 months) and 8 (17%) stabilisation of disease (median duration 6, range 3-17 months). Objective remissions were observed in premenopausal as well as in postmenopausal women, in patients with all categories of dominant localisation of disease and regardless of the oestradiol receptor status of the primary tumour or eventual previous endocrine therapy. One of 4 and 13 of 43 patients who started palliative chemotherapy within or later than 12 months after the last adjuvant course obtained an objective remission. The median survival time from start of therapy of all treated patients was 12 (range 1-40) months. Patients with an objective remission or stable disease and patients with progressive disease had a median survival time of 20 (range 6-40) and 6 (range 1-35) months respectively (p < 0.0001). CONCLUSIONS: Palliative treatment with CMF should not be rejected for patients who have relapsed after adjuvant chemotherapy with the same modality.     

The Charing Cross Hospital experience with temozolomide in patients with gliomas

Temozolomide, a new oral cytotoxic agent, was given to 75 patients with malignant gliomas. The schedule used was for the first course 150 mg/m2 per day for 5 days (i.e. total dose 750 mg/m2), escalating, if no significant myelosuppression was noted on day 22, to 200 mg/m2 per day for 5 days (i.e. total dose 1000 mg/m2) for subsequent courses at 4-week intervals. There were 27 patients with primary disease treated with two courses of temozolomide prior to their radiotherapy and 8 (30%) fulfilled the criteria for an objective response. There were 48 patients whose disease recurred after their initial surgery and radiotherapy and 12 (25%) fulfilled the criteria for an objective response. This gave an overall objective response rate of 20 (27%) out of 75 patients. Temozolomide was generally well tolerated, with little subjective toxicity and predictable myelosuppression. However, the responses induced with this schedule were of short duration and had relatively little impact on overall survival. In conclusion, temozolomide given in this schedule has activity against high grade glioma. However, studies evaluating chemotherapy in primary brain tumours should include a quality-of-life/performance status evaluation in addition to CT or MRI scanning assessment.     

替莫唑胺联合利妥昔单抗对复发的老年原发中枢神经淋巴瘤的应用

Objective: The aim of our study was to analyze the long-term results of rituximab combined with temozolomide in treatment of elderly patients (> 60 years) with relapsed primary central nervous system lymphoma (PCNSL). Methods:Twelve postoperative elderly patients (> 60 years) were treated between August 2004 and October 2009. Temozolomide 100 mg/m2 to 200 mg/m2 days 1 to 7 and 15 to 21 and rituximab 375 mg/m2 days 1, 5, 8, 22. The maximum number of rituximab cycles was two. After one or two cycles of this combination, patients with an objective response and an acceptable level of toxicity continued treatment with single agent temozolomide (days 1 to 5, every 28 days). The overall survival was analyzed by using Kaplan-Meier. Results: The overall survival was 9 months. Toxicity was very mild with no grade 3-4 neurotoxicity toxic events. Conclusion: Rituximab combined with temozolomide seems to yields substantial long-term survival with moderate toxicity for the treatment of elderly relapsed PCNSL.     

Cycles of dose-intensive chemotherapy with peripheral stem cell support in persistent or recurrent platinum-sensitive ovarian cancer

OBJECTIVE: The objective was to determine the toxicity and surgically documented response rate of sequential high-dose chemotherapy with peripheral stem cell support in patients with persistent or recurrent cisplatin-sensitive ovarian cancer. METHODS: Fourteen patients (average age, 45 years) were treated with cyclophosphamide (4.5 g/m2), followed by granulocyte colony-stimulating factor (G-CSF)-stimulated peripheral stem cell harvests. The subsequent regimen prescribed three courses of carboplatin (1 g/m2) and cyclophosphamide (1.5 g/m2 with 2-mercaptoethanesulfonate) every 2 weeks with stem cell support. This was followed by three courses of paclitaxel at 250 mg/m2 every 2 weeks with G-CSF support only. Six patients were entered on the basis of a positive second-look laparotomy and 8 patients had a first recurrence after at least a 6-month disease-free interval. RESULTS: Fourteen patients were entered and 12 patients completed all planned courses of therapy (mean time, 13 weeks). Normal hematopoiesis was reestablished after each cycle. Hospitalization for neutropenic fever occurred in 11/93 cycles (11.8%). Thirteen patients required blood transfusions and in 12 patients platelet transfusions were given. One patient had grade 3 neurotoxicity. An initial elevated CA 125 returned to normal in 7/8 patients (88%) and 71% of patients with measurable disease responded to therapy. There were 2 pathologic complete responders (PCR), making the PCR rate 2/14 or 14% (0-35%). CONCLUSION: Although this regimen was well tolerated and clinical response rates were high, the surgically documented response rate was not clearly superior to conventional salvage regimens in platinum-sensitive patients.     

Phase II study of liarozole in advanced non-small cell lung cancer

The aim of this phase II study was to investigate the efficacy and tolerability of liarozole, a novel benzimidazole derivative, in non-small cell lung cancer (NSCLC). Liarozole 300 mg twice daily orally was evaluated in 14 patients with stage IIIB and IV NSCLC. 8 patients had received prior treatment with chemotherapy and/or radiotherapy. WHO toxicity grading and response criteria were used. Liarozole was well tolerated. Grade 2 toxicities included alopecia (1 patient), dermatological toxicity (5 patients), dry mouth (2 patients) and nausea and vomiting (2 patients). Leukocytosis was seen in 5 patients, including 2 cases with an elevated white cell count pretreatment. Liarozole was discontinued in 1 patient who developed intolerable progressive pruritus associated with an erythematous rash. No objective tumour response was seen, all 14 patients developing progressive disease within 4 months of commencing treatment. Liarozole was well tolerated but was ineffective as single agent therapy in the management of NSCLC. The side-effect profile was compatible with inhibition of retinoic acid degradation.     

Efficacy of recombinant alpha-interferon 2a and 13-cis-retinoic acid in the treatment of squamous cell carcinoma

BACKGROUND: Recent in vitro and in vivo studies hypothesize a synergistic effect of 13-cis-Retinoic Acid (13cRA) and recombinant alpha-IFN 2a (alpha-IFN) in the treatment of squamous cell carcinoma (SqCC). PATIENTS AND METHODS: 35 patients with SqCC in several sites were treated with 13cRA (0.6-1 mg/kg/day) combined with alpha-IFN (6 x 10(6) I.U./day), continuously for 3 months. RESULTS: We observed an objective response in 41% of cases (13/32 evaluable patients) with 5 complete and 8 partial responses. Toxicity was mild and always rapidly reversible, with no haematological side effects. CONCLUSIONS: These preliminary data confirm the feasibility and effectiveness of the combination of 13cRA and alpha-IFN in the therapy of SqCC, also in pre-treated patients, with acceptable toxicity and good compliance.     

Acute myocardial infarction in a patient during dobutamine stress echocardiography

Combined chemotherapy/radiotherapy treatments appear to yield better results in locally advanced non-small-cell lung cancer (NSCLC) than radiotherapy alone. The optimal induction chemotherapy regimen remains to be established. In the present study, chemotherapy with cisplatin and vinorelbine was used prior to radical radiotherapy in Stage III-B NSCLC. Thirty-three patients were entered prospectively into a Phase II study. Treatment consisted of three cycles of chemotherapy with cisplatin 100 mg/m2 on day 1 and vinorelbine 30 mg/m2 on days 1 and 8, followed by thoracic radiotherapy (60 Gy). Twenty-two percent of the 33 patients had grade 3-4 leukopenia, and there were six episodes (in 4 patients) of neutropenia-associated fever. Gastrointestinal toxicity was generally moderate. Peripheral neuropathy was present in 42% of the patients, although in most of them it was slight. The main radiotherapy toxicity was esophagitis grade I-II. Evaluation of response after the third chemotherapy course showed an objective response in 16 patients (48%), whereas in three patients (9%) the disease progressed during therapy. The median survival of the entire group was 13 months. Cisplatin plus vinorelbine followed by radiotherapy is an effective schedule for patients with locally advanced non-small-cell lung cancer.     

Effects of photochemical air pollution and allergen exposure on upper respiratory tract inflammation in asthmatics

Asthma is an inflammatory disease of the airways, and exacerbations of this disease have been associated with high levels of air pollution. The objective of this study was to examine whether ambient air pollution and/or allergen exposure induces inflammatory changes in the upper airways of asthmatics. Sixty patients with intermittent to severe persistent asthma visited the Hospital's Out Patient Clinic every 2 wk for a period of 3 mo, and on each visit a nasal lavage was obtained. Associations between nasal inflammatory parameters and seasonal allergens and/or air pollution exposures were analyzed using linear regression analysis. The study ran from July 3 to October 6, 1995, during which period ozone (8-h mean: 80 micrograms/m3) and PM10 (24-h mean: 40 micrograms/m3) were the major air pollutants; the major aeroallergen was mugwort pollen (24-h mean: 27 pollen grains/m3). Effects on both cellular and soluble markers in nasal lavage were demonstrated for both ozone and mugwort pollen, but not for PM10. Ambient ozone exposure was associated with an increase in neutrophils (112% per 100 micrograms/m3 increase in 8-h average ozone concentration), eosinophils (176%), epithelial cells (55%), IL-8 (22%), and eosinophil cationic protein (ECP) (19%). Increases in environmental mugwort pollen counts were associated with an increase in nasal eosinophils (107% per 100 pollen/m3) and ECP (23%), but not with neutrophils, epithelial cells, or lL-8. This study demonstrated that both ambient ozone and allergen exposure are associated with inflammatory responses in the upper airways of subjects with asthma, although the type of inflammation is qualitatively different.     

Clindamycin and primaquine therapy for mild-to-moderate episodes of Pneumocystis carinii pneumonia in patients with AIDS: AIDS Clinical Trials Group 044

The objective of this prospective, noncomparative study was to assess the safety and efficacy of clindamycin and primaquine therapy for mild-to-moderate pneumocystis pneumonia (defined as a difference of < 40 mm Hg between the alveolar and the arterial oxygen determinations) in patients with AIDS. In the first part of the study, 22 patients were treated with iv clindamycin (900 mg every 8 hours) for the first 10 days, and then their therapy was switched to oral clindamycin (450 mg every 6 hours) for an additional 11 days. In the second part of the study, 38 patients were treated entirely with oral clindamycin (600 mg every 8 hours). All patients were treated with oral primaquine base (30 mg once daily). Fifty-five (92%) of 60 patients responded to the study treatment. Forty-six (77%) of 60 patients completed a full course of therapy. Of the nine patients with treatment-limiting toxic effects, four had only a mild rash. This study indicates that the combination of clindamycin and primaquine is an effective and well-tolerated therapy for mild-to-moderate pneumocystis pneumonia in patients with AIDS. Entirely oral therapy appears to be as effective as initial therapy with iv clindamycin.     

A defect in the mitochondrial import of mutant Mn-superoxide dismutase produced in Sf21 cells

The objective of this study was to assess the effect on serum lipid levels of the substitution of simvastatin for fluvastatin at a dose ratio of 8:1 (fluvastatin to simvastatin). A secondary objective was to determine the number of patients at goal lipid levels before and after this substitution. The study included 60 outpatients with hyperlipidemia who had received a constant dose of fluvastatin for at least 6 weeks. After a baseline 12-hour lipid profile (total cholesterol, triglycerides, high-density lipoprotein, and low-density lipoprotein [LDL]) was obtained, patients were switched from fluvastatin to simvastatin at an 8:1 dose ratio. Patients were instructed to split the simvastatin tablets in half with a pill splitter and to take one half-tablet at bedtime. A repeat lipid profile and liver function testing were performed after 6 to 8 weeks of simvastatin therapy. Lipid components were compared before and during simvastatin therapy using a paired t test. Target LDL levels were based on guidelines issued by the National Cholesterol Education Program. Fifty-six patients completed the study. No change in lipid components was observed, except for a statistically significant decrease in LDL. The majority of patients had a decrease in LDL levels, rather than an increase, after the conversion to simvastatin. Six patients required a dose increase of simvastatin in response to increased LDL levels. Forty-one percent of patients achieved goal LDL levels with simvastatin, compared with 30% with fluvastatin. Four patients withdrew from the study, two because of troublesome side effects and two for failure to complete the protocol. The results show that simvastatin can be substituted for fluvastatin at a dose ratio of 8:1 without loss of lipid control in the majority of patients and that by using this ratio and splitting tablets, significant cost savings can be realized.     

A phase I clinical trial of murine monoclonal antibody D612 in patients with metastatic gastrointestinal cancer

In a phase I study, 21 patients with metastatic adenocarcinoma of the gastrointestinal tract received the murine monoclonal antibody D612. This antibody is directed at a M(r) 48,000 antigen restrictively expressed on tumors of the gastrointestinal tract and to a limited degree on normal gastrointestinal mucosa. Patients received total doses of 10-180 mg/m2 administered as single or multiple doses of 1-100 mg/m2 over an 8-day period. Dose-limiting toxicity was secretory diarrhea. A single dose of 100 mg/m2 exceeded guidelines for maximal tolerated dose. Higher total doses were achieved in subsequent patients by using repeated administration of lower doses. Three of five patients receiving 60 mg/m2 for 3 doses (180 mg/m2 total dose) experienced grade 3 diarrhea and could not complete the prescribed course. The dose of 40 mg/m2 administered on days 1, 4, and 8 (total dose, 120 mg/m2) has been selected as the dose for phase II studies. The pharmacokinetics of D612 is best described by a one-compartment model with a mean t1/2 of 48 +/- 3 h (SEM). Eighteen of 21 patients developed human anti-mouse antibody (HAMA). Patients who developed high levels of HAMA demonstrated a more rapid clearance of the day 8 dose than those who developed low levels of HAMA. In all patients studied, a component of HAMA was directed at the D612 variable region. With one exception, serum from all patients with detectable antibody to the D612 variable region demonstrated anti-paratope reactivity. Thirty-four % of known metastatic sites demonstrated uptake of radiolabeled D612. There were no objective antitumor responses in this phase I trial. The antitumor effect of D612 in vitro has been shown to be potentiated by interleukin 2 and recombinant human macrophage colony-stimulating factor. A phase II study of D612 administered in combination with cytokines that enhance human effector function is presently ongoing.     

A dose-finding study of ifosfamide by three-day continuous infusion in pretreated, advanced breast cancer patients

The purpose of the study was to establish the maximum tolerated dose of ifosfamide, administered over 72 hr, in metastatic breast cancer patients, pretreated with chemotherapy. Ifosfamide and mesna were given at the same dose, in the same solution, using a portable Pharmacia CADD-1 pump connected to a central venous access, at three dose levels: 7.5 g/m2 (6 patients), 9 g/m2 (8 patients), 10.5 g/m2 (3 patients); the courses were repeated every 3 weeks. Seventeen patients with a median age of 55 years (range, 34-68) and median performance status of 0 (range, 0-2) were treated. The patients were pretreated with a median of 2 (range, 1-3) prior regimens including anthracyclines in 14 patients and paclitaxel in 9. Dose-limiting toxicity was defined as the occurrence of any of the following events in > or = 2/6 patients: absolute neutrophil count < 500/ml for > 7 days or < 100/ml for > 3 days; febrile neutropenia; grade 4 thrombocytopenia; any grade > or = 3 nonhematologic toxicity. The dose-limiting toxicities were febrile neutropenia and grade 4 thrombocytopenia in 2/3 patients treated at 10.5 g/m2. Seven patients achieved an objective response (response rate 41%; 95% CI, 18% to 67%). We conclude that 72-hr infusion of ifosfamide is feasible in ambulatory patients. The recommended dose for phase II studies is 9 g/m2, with courses repeated every 21 days.     

Engraftment of allogeneic hematopoietic progenitor cells with purine analog-containing chemotherapy: harnessing graft-versus-leukemia without myeloablative therapy

The immune-mediated graft-versus-leukemia effect is important to prevent relapse after allogeneic progenitor cell transplantation. This process requires engraftment of donor immuno-competent cells. The objective of this study was to assess the feasibility of achieving engraftment of allogeneic peripheral blood or bone marrow progenitor cell after purine analog containing nonmyeloablative chemotherapy. Patients with advanced leukemia or myelodysplastic syndromes (MDS) who were not candidates for a conventional myeloablative therapy because of older age or organ dysfunction were eligible. All patients had an HLA-identical or one-antigen-mismatched related donor. Fifteen patients were treated (13 with acute myeloid leukemia and 2 with MDS). The median age was 59 years (range, 27 to 71 years). Twelve patients were either refractory to therapy or beyond first relapse. Eight patients received fludarabine at 30 mg/m2/d for 4 days with idarubicin at 12 mg/m2/d for 3 days and ara-c at 2 g/m2/d for 4 days (n = 7) or melphalan at 140 mg/m2/d (n = 1). Seven patients received 2-chloro-deoxyadenosine at 12 mg/m2/d for 5 days and ara-C 1 at g/m2/d for 5 days. Thirteen patients received allogeneic peripheral blood stem cells and 1 received bone marrow after chemotherapy. Graft-versus-host disease (GVHD) prophylaxis consisted of cyclosporine and methyl-prednisolone. Treatment was generally well tolerated, with only 1 death from multiorgan failure before receiving stem cells. Thirteen patients achieved a neutrophil count of greater than 0.5 x 10(9)/L a median of 10 days postinfusion (range, 8 to 17 days). Ten patients achieved platelet counts of 20 x 10(9)/L a median of 13 days after progenitor cell infusion (range, 7 to 78 days). Eight patients achieved complete remissions (bone marrow blasts were < 5% with neutrophil recovery and platelet transfusion independence) that lasted a median of 60 days posttransplantation (range, 34 to 170+ days). Acute GVHD grade > or = 2 occurred in 3 patients. Chimerism analysis of bone marrow cells in 6 of 8 patients achieving remission showed > or = 90% donor cells between 14 and 30 days postinfusion, and 3 of 4 patients remaining in remission between 60 and 90 days continued to have > or = 80% donor cells. We conclude that purine analog-containing nonmyeloablative regimens allow engraftment of HLA-compatible hematopoietic progenitor cells. This approach permits us to explore the graft-versus-leukemia effect without the toxicity of myeloablative therapy and warrants further study in patients with leukemia who are ineligible for conventional transplantation with myeloablative regimens either because of age or concurrent medical conditions.     

Encapsulation of Cryptococcus neoformans with glucuronoxylomannan inhibits the antigen-presenting capacity of monocytes

PURPOSE: The combination of carmustine (BCNU), dacarbazine (DTIC), cisplatin (DDP), and tamoxifen (Tam) has been reported in small series to provide a response rate of 50%, but with significant myelosuppression and risk of thromboembolic complications. We performed this phase II study to assess the antitumor activity and important toxicities of this combination in the cooperative group setting. PATIENTS AND METHODS: Seventy-nine eligible patients were treated with BCNU 150 mg/m2/d, every 6 weeks, DTIC 220 mg/m2/d on days 1 to 3 every 3 weeks, DDP 25 mg/m2/d on days 1 to 3 every 3 weeks, and Tam 20 mg orally daily throughout treatment. Treatment cycles were repeated every 6 weeks in responding or stable patients for a maximum duration of 1 year. RESULTS: Twelve objective responses were achieved (response rate 15%, 95% confidence interval 8%-25%). Five responses were complete (CR) and seven were partial (PR). The median response duration was 8+ (range, 4-19+) months, (16+ [4-19+] for CR and 8+ [4-11] for PR), and the median survival of the entire group was 9 months. The toxicities were predominantly neutropenia and thrombocytopenia. Four patients developed thromboembolic events. Two patients died while on protocol therapy, one with complications of neutropenia, and the other with disease progression. CONCLUSION: The activity of this regimen is in the range reported for single agents or DTIC plus DDP, and the addition of BCNU and Tam appears to increase toxicity. We do not recommend this combination for routine treatment of advanced melanoma or as the control arm in randomized studies of combination therapy.     

Recombinant human granulocyte colony-stimulating factor attenuates inflammatory responses in septic patients with neutropenia

OBJECTIVE: The objective of this study was to determine the effects of recombinant human granulocyte colony-stimulating factor (rhG-CSF) administration in septic patients with neutropenia. METHODS: Twenty consecutive septic patients were administered rhG-CSF subcutaneously (2 microg x kg(-1) x d(-1)) for 5 days (group G). They were compared with 14 septic patients treated earlier without rhG-CSF (group N). All patients in both groups met the criteria of total leukocyte count (TLC) less than 5,000/mm3 and C-reactive protein (CRP) more than 10 mg/dL. Changes in TLC, absolute neutrophil count (ANC), CRP, respiratory index (RI), Acute Physiology and Chronic Health Evaluation (APACHE) II score, and Goris's Multiple Organ Failure (MOF) index were evaluated. In addition, nucleated cell count (NCC), differentiation in bone marrow aspiration, neutrophil phagocytic and bactericidal activity, serum concentrations of interleukin-6 (IL-6) and IL-8 as inflammatory markers, and plasma concentration of leukocyte elastase (LE) as an indicator of the tissue injury were evaluated in group G. RESULTS: In group G, TLC, ANC, NCC, and neutrophil functions increased significantly, whereas CRP, IL-6, and IL-8 decreased reciprocally. There was no deterioration of LE and RI. Consequently, the APACHE II score and MOF index improved. In group N, however, CRP showed no change concomitant with the APACHE II score and MOF index. CONCLUSION: Administration of rhG-CSF attenuates inflammatory responses without inducing tissue injury in septic patients with neutropenia.     

Phase II trial of edatrexate in patients with metastatic colorectal cancer

Edatrexate is an analog of methotrexate which in vitro demonstrated activity against human colon cancer xenografts grown in nude mice. In a phase II trial, 12 patients with metastatic colorectal cancer and no prior chemotherapy were treated with Edatrexate 80 mg/m2/week for an initial period of 8 weeks. No objective responses were observed. Edatrexate is inactive against colon cancer at the dose and schedule used in this trial.     

Early release of proinflammatory cytokines after lung transplantation

BACKGROUND: Systemic hypotension may complicate the early postoperative period after lung transplantation. A release of proinflammatory cytokines secondary to lung ischemia/reperfusion injury could be involved in the pathogenesis of this early hemodynamic failure (EHF). Study objective: To assess prospectively whether the occurrence of EHF is associated with a release of cytokines in the systemic circulation. DESIGN: Blood samples were taken daily during the first postoperative week in 26 patients who underwent a double or a single-lung transplantation. These patients were divided into three groups: 7 patients who experienced EHF and subsequently died (EHF group); 15 patients without EHF (control group); and 4 patients without EHF but with an identified sepsis (sepsis group). The serum levels of interleukin (IL)-1beta, tumor necrosis factor-alpha (TNF-alpha), IL-6, and IL-8 were compared among the three groups. RESULTS: In the EHF group, the levels of each cytokine peaked at day 1 postoperatively. Cytokine levels at day 1 were significantly higher in the EHF group than in the control group (p<0.0006) or in the sepsis group (p<0.003 except for TNF-alpha). CONCLUSION: We conclude that EHF is associated with a massive release of proinflammatory cytokines that could play a determinant role in the pathogenesis of this complication.
