Local activation of immune response in bladder cancer patients treated with intraarterial infusion of recombinant interleukin-2.

Tumor regression induced in cancer patients by i.v. infusion of interleukin-2 (IL-2) is often accompanied by severe side effects. To investigate whether local administration would affect immune response without the side effects, two 5-day cycles of continuous intraarterial [internal iliac artery] infusion of recombinant interleukin-2 (rIL-2) were performed in 12 patients with transitional cell carcinoma (tumor stage 1, node stage 0, metastasis stage 0, and grade 1-2) of the bladder. Four groups of 3 patients were treated at each of 4 escalating doses of rIL-2 (18 x 10(3), 18 x 10(4), 18 x 10(5), and 18 x 10(6) IU/m2/day) throughout the course of the two IL-2 cycles. This treatment was effective in inducing a marked intratumor inflammatory response, consisting mainly of T-lymphocytes and macrophages. A remarkable dose-dependent increase in the levels of soluble CD25 was observed in the urine of all patients, which was associated constantly with an enhanced number of intratumor CD25+ cells. Intratumor macrophages were often immunoreactive for interleukin-1 and/or tumor necrosis factor, suggesting an activated status. Increased levels of soluble CD25 and CD25+ lymphocytes were observed in peripheral blood only at the two highest doses of rIL-2, while increased percentages of circulating HLA-DR+ and CD71+ lymphoid cells and enhancement of CD3+/CD16+ T-lymphocytes were found at lower doses. Peripheral blood eosinophils were augmented in almost all patients but were rarely increased in situ. We provide evidence that continuous intraarterial infusion of rIL-2 activates host immune response, acting preferentially at the tissue level.
Etanercept, infliximab, and leflunomide in established rheumatoid arthritis: clinical experience using a structured follow up programme in southern Sweden.

To explore the feasibility of prospectively monitoring treatment efficacy and tolerability of infliximab, etanercept, and leflunomide over a two year period in patients with established rheumatoid arthritis (RA) in clinical practice using a structured protocol.



All patients with RA at seven centres in southern Sweden, for whom at least two disease modifying antirheumatic drugs, including methotrexate, had failed or not been tolerated, who started treatment with either infliximab, etanercept, or leflunomide were included. They were evaluated at predefined times using a standardised protocol including items required for evaluating response to the American College of Rheumatology (ACR) or EULAR criteria. All adverse events were recorded using World Health Organisation terminology. Concomitant treatment and survival while receiving a drug were recorded.



During the study 166 patients were treated with etanercept, 135 with infliximab, and 103 with leflunomide. Treatment response as determined by the ACR and EULAR response criteria was similar for the tumour necrosis factor (TNF) blockers. The TNF blockers performed significantly better than leflunomide both as determined by the response criteria and by survival on drug analysis. Thus 79% and 75% continued to receive etanercept or infliximab compared with 22% of patients who started leflunomide after 20 months. The spectrum of side effects did not differ from those previously reported in the clinical trials. The initial two year experience of a protocol for postmarketing surveillance of etanercept, infliximab, and leflunomide shows that a structured protocol with central data handling can be used in clinical practice for documenting the performance of newly introduced drugs.



Efficacy data for the TNF blockers comply with results in clinical trials, whereas leflunomide appeared to perform worse than in clinical trials. Prolonged monitoring is required to identify possible rare side effects.
A comparative study of the clinical efficacy of nedocromil sodium and placebo. How does cromolyn sodium compare as an active control treatment?

Nedocromil sodium and cromolyn sodium are the only two currently available nonsteroid anti-inflammatory agents for treatment of asthma. Clinical differences between the two agents remain under continuous investigation with reports differentiating the two on the basis of atopy of the patient and reversibility of bronchoconstriction. This study investigated the efficacy of nedocromil sodium (4 mg, qid) for treatment of mild-to-moderate asthma in comparison to placebo using cromolyn sodium (2 mg, qid) as an active control treatment. Patients were primarily allergic asthmatics (with at least 15% reversibility) previously maintained on a regimen of regular bronchodilator therapy. During a 2-week run-in period, the patient's slow-release theophylline therapy was removed, and the patients were randomized to treatment after deterioration of asthma control (asthma symptom summary score of 3 for 7 of the 14 days). After 8 weeks of treatment, patients were returned to as occasion requires bronchodilator therapy, as per the 2-week baseline period. The results demonstrate that patients treated with nedocromil sodium showed statistically significant improvements during the primary time period (mean weeks 3 through 8) over placebo-treated patients as evidenced by all indexes of asthma symptoms, pulmonary function measures, and decreased bronchodilator reliance (p<0.05). Patients treated with cromolyn sodium demonstrated similar improvements over placebo-treated patients. Comparisons between nedocromil sodium and cromolyn sodium showed the two agents to be comparable in this group of primarily allergic patients with reversible disease. Between-group differences were noted for 3 of the 13 variables (nighttime asthma, FEV1, and forced expiratory flow rate between 25 % and 75% of the FVC) in favor of cromolyn sodium when the data were pooled during the primary time period. The number of patients missing 1 or more days from work/school/regular activity due to asthma was significantly fewer compared with placebo, and favoring nedocromil sodium over cromolyn sodium. No differences were observed among the three treatments for adverse events. This study demonstrated that in primarily allergic patients with reversible airways disease, nedocromil sodium and cromolyn sodium are both significantly more effective than placebo for treatment of mild-to-moderate asthma.
Vaccination with NY-ESO-1 overlapping peptides mixed with Picibanil OK-432 and montanide ISA-51 in patients with cancers expressing the NY-ESO-1 antigen.

We conducted a clinical trial of an NY-ESO-1 cancer vaccine using 4 synthetic overlapping long peptides (OLP; peptides #1, 79-108; #2, 100-129; #3, 121-150; and #4, 142-173) that include a highly immunogenic region of the NY-ESO-1 molecule. Nine patients were immunized with 0.25 mg each of three 30-mer and a 32-mer long NY-ESO-1 OLP mixed with 0.2 KE Picibanil OK-432 and 1.25 mL Montanide ISA-51. The primary endpoints of this study were safety and NY-ESO-1 immune responses. Five to 18 injections of the NY-ESO-1 OLP vaccine were well tolerated. Vaccine-related adverse events observed were fever and injection site reaction (grade 1 and 2). Two patients showed stable disease after vaccination. An NY-ESO-1-specific humoral immune response was observed in all patients and an antibody against peptide #3 (121-150) was detected firstly and strongly after vaccination. NY-ESO-1 CD4 and CD8 T-cell responses were elicited in these patients and their epitopes were identified. Using a multifunctional cytokine assay, the number of single or double cytokine-producing cells was increased in NY-ESO-1-specific CD4 and CD8 T cells after vaccination. Multiple cytokine-producing cells were observed in PD-1 (-) and PD-1 (+) CD4 T cells. In conclusion, our study indicated that the NY-ESO-1 OLP vaccine mixed with Picibanil OK-432 and Montanide ISA-51 was well tolerated and elicited NY-ESO-1-specific humoral and CD4 and CD8 T-cell responses in immunized patients.
Italian validation of INQoL, a quality of life questionnaire for adults with muscle diseases.

A quality of life (QoL) questionnaire for neuromuscular diseases was recently constructed and validated in the United Kingdom in a sample of adult patients with a variety of muscle disorders. Preliminary results suggested it could be a more relevant and practical measure of QoL in muscle diseases than generic health measures of QoL. The purpose of our work was: (i) To validate INQoL in Italy on a larger sample of adult patients with muscle diseases (ii) to compare INQoL to SF-36.



We have translated into Italian and applied language adaptations to the original UK INQoL version. We studied 1092 patients with different muscle disorders and performed (i) test-retest reliability (n = 80); (ii) psychometric (n = 345), known-group (n = 1092), external criterion (n = 70), and concurrent validity with SF-36 (n = 183).



We have translated and formally validated the Italian version of INQoL confirming and extending results obtained in the United Kingdom. In addition to good results in terms of reliability, known-group and criterion validity, a comparison with the SF-36 scales showed a stronger association between INQoL total index and SF-36 physical (r = -0.72) than mental (r = -0.38) summary health indexes. When considering comparable domains of INQoL and SF-36 with respect to an objective measure of muscle strength assessment (MMRC), regression analysis showed a stronger correlation using INQoL rather than SF-36 scores.



INQoL is recommended to assess QoL in muscle diseases because of its ability to capture physical limitations that are specifically relevant to the muscle condition.
Bridging therapy with low molecular weight heparin in patients with atrial fibrillation undergoing percutaneous coronary intervention with stent implantation: the AFCAS study.

Recent reports have provided evidence that bridging therapy with low-molecular-weight heparin (LMWH) may increase bleeding complications in patients with atrial fibrillation (AF) on oral anticoagulation undergoing percutaneous coronary intervention (PCI). We sought to assess mid-term bleeding and thromboembolic events in patients from the AFCAS registry discharged on triple therapy (TT).



AFCAS is a multicenter, prospective registry enrolling patients with AF undergoing PCI. The primary endpoints were: 1) bleeding complications as defined by the bleeding academic research criteria (BARC); 2) a composite of cardiac and cerebrovascular events (MACCE) at 3 and 12 month follow-ups.



Altogether 663 out of 929 consecutive patients were discharged on TT, either on oral vitamin K antagonist (VKA-TT) (n=498) or bridging LMWH-TT (n=165). Patients on LMWH-TT had more often diabetes, heart failure, and hypertension compared to those on VKA-TT. The rates of major bleeding events (BARC≥3) (11.5% vs. 6.0%, p=0.03) as well as MACCE (11.5% vs. 5.0%, p=0.006) were higher in the LMWH-TT group compared to VKA-TT group at 3 months follow-up. In a Cox multivariate regression model and propensity-score matched analysis LMWH-TT increased the risk for major BARC bleeding events at 3 and 12 month follow-ups.



In this large, prospective, real-world population of patients with AF undergoing PCI patients discharged on LMWH-TT had a significantly higher risk for major bleeds in comparison to patients discharged on VKA-TT. LMWH-bridging therapy appeared harmful in this subset of patient on oral anticoagulation.
Subclinical neuropathy among Diabetes Control and Complications Trial participants without diagnosable neuropathy at trial completion: possible predictors of incident neuropathy?

We sought to evaluate the prevalence of subclinical neuropathy in intensive and conventional treatment groups at completion of the Diabetes Control and Complications Trial (DCCT).



We assessed neuropathy using nerve conduction results obtained at DCCT completion after stratifying the DCCT cohort to exclude subjects with progressively less severe degrees of diagnosable neuropathy. We began with those who had confirmed clinical neuropathy (the primary DCCT end point) and eventually excluded all subjects with any clinical or electrodiagnostic evidence of neuropathy.



After excluding subjects with confirmed clinical neuropathy at DCCT completion, 8 of 10 nerve conduction measures (including all lower-extremity measures) were significantly improved in the intensive treatment group (O'Brien rank-sum test across all nerve conduction measures, P < 0.0001). Conduction velocity group differences were substantial, and the peroneal conduction velocity averaged 3.1 m/s faster in the intensive compared with the conventional treatment group (45.1 vs. 42.0 m/s, P < 0.0001). Numerous significant differences in median and peroneal motor conduction velocities favoring the intensive treatment group persisted, regardless of the exclusion criteria applied.



Intensive and conventional treatment group subjects without diagnosable neuropathy at DCCT completion had significant differences in electrophysiologic measurements favoring the intensive treatment group. Differences in subsequent incident neuropathy between the original treatment groups may reflect, in part, their levels of subclinical neuropathy at DCCT completion, rather than persistent metabolic effects.
Pulmonary function abnormalities and asthma are prevalent in children with sickle cell disease and are associated with acute chest syndrome.

Pulmonary diseases form major sources of morbidity and mortality in children with sickle cell disease (SCD). The objective of the study was to determine the prevalence of lung function abnormalities and asthma and their association with acute chest syndrome (ACS) in children with SCD. This was a cross-sectional retrospective study of 127 children with SCD; we collected information regarding ACS and asthma and pulmonary function test (PFT) data. Based on PFT results, the patients were assigned to one pattern of lung function [normal, obstructive lung disease (OLD), restrictive lung disease (RLD)]. Statistical analyses included Pearson correlation, prevalence odds ratio (POR), cross-tabulation, and multiple binary logistic regression. OLD was noted in 35% and RLD in 23% of the patients, with the remainder exhibiting a normal PFT pattern. Forty-six percent of patients had asthma, 64% of whom had a history of ACS. OLD (r = .244, P = .008, POR = 2.8) and asthma (r = .395, P < .001, POR = 5.4) were significantly associated with a history of ACS. There was a negative correlation between having normal PFT data and a history of ACS (r = -.289, P = .002, POR = .3). Asthma and pulmonary function abnormalities are prevalent in children with SCD, with OLD being more common than RLD. There is an association between asthma, OLD, and ACS, however causality cannot be proven due to the study design. We stress the importance of actively investigating for a clinical diagnosis of asthma in all patients with SCD and suggest that PFT data may help detect patients at lower risk for ACS.
Symptomatic effects of chondroitin 4 and chondroitin 6 sulfate on hand osteoarthritis: a randomized, double-blind, placebo-controlled clinical trial at a single center.

To evaluate the symptomatic effects of highly purified chondroitin 4 and chondroitin 6 sulfate (CS) therapy in patients with osteoarthritis (OA) of the hand.



This investigator-initiated, single-center, randomized, double-blind, placebo-controlled clinical trial included 162 symptomatic patients with radiographic evidence of hand OA (American College of Rheumatology criteria). Inclusion criteria included patient's assessment of global spontaneous hand pain of at least 40 mm on a 0-100-mm visual analog scale (VAS) and functional impairment of at least 6 (0-30 scale) on the Functional Index for Hand OA (FIHOA) in the most symptomatic hand. Patients received either 800 mg of CS (n = 80 patients) or placebo (n = 82 patients) once daily for 6 months and were analyzed in an intent-to-treat approach. The two primary outcomes were the change in the patient's assessment of global spontaneous hand pain and in hand function (by FIHOA score) from baseline to month 6. Secondary outcomes were improvement in grip strength, duration of morning stiffness, acetaminophen consumption, and the investigator's global impression of treatment efficacy.



There was a significantly more pronounced decrease in the patient's global assessment of hand pain in the CS group than in the placebo group (difference VAS scores -8.7 mm; P = 0.016). Hand function improved significantly more in the CS group than in the placebo group (difference in FIHOA scores -2.14; P = 0.008). There was a statistically significant between-group difference in favor of CS for the duration of morning stiffness and for the investigator's global impression of treatment efficacy. Changes in grip strength, acetaminophen consumption, and safety end points were not significantly different between the two groups.



This study demonstrates that CS improves hand pain and function in patients with symptomatic OA of the hand and shows a good safety profile.
A comparative study of reaction times between type II diabetics and non-diabetics

Aging has been shown to slow reflexes and increase reaction time to varied stimuli. However, the effect of Type II diabetes on these same reaction times has not been reported. Diabetes affects peripheral nerves in the somatosensory and auditory system, slows psychomotor responses, and has cognitive effects on those individuals without proper metabolic control, all of which may affect reaction times. The additional slowing of reaction times may affect every-day tasks such as balance, increasing the probability of a slip or fall.



Reaction times to a plantar touch, a pure tone auditory stimulus, and rightward whole-body lateral movement of 4 mm at 100 mm/s2 on a platform upon which a subject stood, were measured in 37 adults over 50 yrs old. Thirteen (mean age = 60.6 +/- 6.5 years) had a clinical diagnosis of type II diabetes and 24 (mean age = 59.4 +/- 8.0 years) did not. Group averages were compared to averages obtained from nine healthy younger adult group (mean age = 22.7 +/- 1.2 years).



Average reaction times for plantar touch were significantly longer in diabetic adults than the other two groups, while auditory reaction times were not significantly different among groups. Whole body reaction times were significantly different among all three groups with diabetic adults having the longest reaction times, followed by age-matched adults, and then younger adults.



Whole body reaction time has been shown to be a sensitive indicator of differences between young adults, healthy mature adults, and mature diabetic adults. Additionally, the increased reaction time seen in this modality for subjects with diabetes may be one cause of increased slips and falls in this group.
A phase I multidose study of dacetuzumab (SGN-40; humanized anti-CD40 monoclonal antibody) in patients with multiple myeloma.

This first-in-human, phase I study evaluated the safety, maximum-tolerated dose, pharmacokinetics, and antitumor activity of dacetuzumab in 44 patients with advanced multiple myeloma. Patients received intravenous dacetuzumab, either in 4 uniform weekly doses (first 4 cohorts) or using a 5-week intrapatient dose escalation schedule (7 subsequent cohorts; the last 3 cohorts received steroid pre-medication). An initial dose of 4 mg/kg dacetuzumab exceeded the maximum-tolerated dose for uniform weekly dosing. Intrapatient dose escalation with steroid pre-medication appeared effective in reducing symptoms of cytokine release syndrome and the maximum-tolerated dose with this dosing schema was 12 mg/kg/week. Adverse events potentially related to dacetuzumab included cytokine release syndrome symptoms, non-infectious ocular inflammation, and elevated hepatic enzymes. Peak dacetuzumab blood levels increased with dose. Nine patients (20%) had a best clinical response of stable disease. The observed safety profile suggested that dacetuzumab may be combined with other multiple myeloma therapies. Two combination trials are ongoing. Clinical trials gov identifier: NCT00079716.
Airway responses and inflammation in subjects with asthma after four days of repeated high-single-dose allergen challenge

Both standard and low-dose allergen provocations are an established tool in asthma research to improve our understanding of the pathophysiological mechanism of allergic asthma. However, clinical symptoms are less likely to be induced. Therefore, we designed a protocol for repetitive high-dose bronchial allergen challenges to generate clinical symptoms and airway inflammation.



A total of 27 patients aged 18 to 40 years with positive skin-prick tests and mild asthma underwent repetitive high-dose allergen challenges with household dust mites for four consecutive days. Pulmonary function and exhaled NO were measured at every visit. Induced sputum was analysed before and after the allergen challenges for cell counts, ECP, IL-5, INF-γ, IL-8, and the transcription factor Foxp3.



We found a significant decrease in pulmonary function, an increased use of salbutamol and the development of a late asthmatic response and bronchial hyperresponsiveness, as well as a significant induction of eNO, eosinophils, and Th-2 cytokines. Repeated provocation was feasible in the majority of patients. Two subjects had severe adverse events requiring prednisolone to cope with nocturnal asthma symptoms.



Repeated high-dose bronchial allergen challenges resulted in severe asthma symptoms and marked Th-2-mediated allergic airway inflammation. The high-dose challenge model is suitable only in an attenuated form in diseased volunteers for proof-of-concept studies and in clinical settings to reduce the risk of severe asthma exacerbations.
Successful alemtuzumab retreatment in progressive B-cell chronic lymphocytic leukemia: a multicenter survey in 30 patients

Although retreatment with alemtuzumab in relapsing B-cell chronic lymphocytic leukemia (CLL) may be beneficial, there has thus far been no thorough analysis available on this topic. Data were collected from 30 chemotherapy-pretreated patients with progressive CLL who had received alemtuzumab twice in consecutive, distinct therapy lines. The median dose of alemtuzumab retreatment was 402 mg (range, 43–1,090 mg). Retreatment with alemtuzumab induced an overall response rate of 47%. From the start of alemtuzumab retreatment, median progression-free survival (PFS) and overall survival (OS) were 6.3 and 20.0 months, respectively. Response rates, PFS and OS upon alemtuzumab retreatment were correlated with response to initial alemtuzumab treatment, the time interval between the initial course of alemtuzumab and start of retreatment, and the hemoglobin concentration prior to retreatment. Reported toxicities from 24 cases included infections (50%), febrile reactions upon alemtuzumab administration (38%), exanthema (21%), and grade 4 neutropenia (13%) and thrombocytopenia (17%). We conclude that alemtuzumab retreatment represents an effective and tolerable therapeutic option for selected patients with CLL.
