Single-agent cetuximab is safe and active in elderly patients with advanced colorectal cancer (CRC). A cetuximab-capecitabine combination has not previously been tested in elderly patients with advanced CRC. Material and Methods. Sixty-six patients with advanced CRC were treated with cetuximab as a 400 mg/m 2 i.v. infusion followed by 250 mg/m 2 i.v. weekly plus capecitabine at a dose of 1,250 mg/m 2 every 12 hours. After the inclusion of 27 patients, the protocol was amended for safety reasons, reducing the dose of capecitabine to 1,000 mg/m 2 every 12 hours. Thirty-nine additional patients were treated with the reduced dose of capecitabine. Results. The overall response rate was 31.8%. KRAS status was determined in 58 patients (88%). Fourteen of 29 patients with wild-type KRAS tumors responded (48.3%; 95% confidence interval [CI], 29.4%-67.5%), compared with six of 29 patients with mutant KRAS tumors (20.7%; 95% CI, 8.0%-39.7%). The median progression-free survival (PFS) interval was 7.1 months. The median PFS interval for patients whose tumors were wild-type KRAS was significantly longer than for those with mutant KRAS tumors (8.4 months versus 6.0 months; p = 024). The high incidence of severe paronychia (29.6%) declined (7.7%) after capecitabine dose adjustment. Conclusions. Cetuximab plus capecitabine at a dose of 1,000 mg/m 2 every 12 hours may be an alternative to more aggressive regimens in elderly patients with advanced wild-type KRAS CRC. © AlphaMed Press. Source

The role of CB2 cannabinoid receptors in the behavioral and neurochemical changes induced by intracaudate administration of 6-hydroxydopamine (6-OHDA) was evaluated. 6-OHDA (12 μg/4 μL) or its vehicle was injected in the caudate-putamen (CPu) of mice overexpressing the CB2 cannabinoid receptor (CB2xP) and wild type (WT) mice. Motor impairment, emotional behavior, and cognitive alterations were evaluated. Tyrosine hydroxylase (TH), glial fibrillary acidic protein (GFAP), and ionized calcium-binding adapter molecule 1 (Iba-1) were measured by immunocytochemistry in the CPu and/or substantia nigra (SN) of CB2xP mice and WT mice. Oxidative/nitrosative and neuroinflammatory parameters were also measured in the CPu and cortex of 6-OHDA-treated and sham-treated mice. 6-OHDA-treated CB2xP mice presented significantly less motor deterioration than 6-OHDA-treated WT mice. Immunocytochemical analysis of tyrosine hydroxylase in the SN and CPu revealed significantly fewer lesions in CB2xP mice than in WT mice. GFAP and Iba-1 immunostaining revealed less astrocyte and microglia recruitment to the treated area of the CPu in CB2xP mice. Malonyldialdehyde (MDA) concentrations were lower in the striatum and cerebral cortex of sham-treated CB2xP mice than in sham-treated WT mice. The administration of 6-OHDA increased MDA levels in both WT mice and CB2xP mice; it increased the oxidized (GSSG)/reduced (GSH) glutathione ratio in the striatum in WT mice alone compared with matched sham-treated controls. The results revealed that overexpression of CB2 cannabinoid receptors decreased the extent of motor impairment and dopaminergic neuronal loss, reduced the recruitment of astrocytes and microglia to the lesion, and decreased the level of various oxidative parameters. These results suggest that CB2 receptors offer neuroprotection against dopaminergic injury. © 2012 Elsevier Inc. Source

Objectives: To develop evidence-based recommendations for management of calcium pyrophosphate deposition (CPPD). Methods: A multidisciplinary guideline development group of 15 experts, representing 10 European countries, generated key propositions for management of CPPD using a Delphi consensus approach. For each recommendation research evidence was searched systematically. Whenever possible, the effect size and number needed to treat for efficacy and RR or OR for side effects were calculated for individual treatment modalities. Strength of recommendation was assessed by the European League Against Rheumatism visual analogue scale. Results: Nine key recommendations were generated, including topics for general management, treatment of acute attacks, prophylaxis against recurrent acute attacks and management of chronic symptoms. It was recommended that optimal treatment requires both non-pharmacological and pharmacological treatments. For acute CPP crystal arthritis, cool packs, temporary rest and joint aspiration combined with steroid injection are often sufficient. For prophylaxis or chronic inflammatory arthritis with CPPD, oral non-steroidal anti-inflammatory drugs with gastroprotective treatment and/or low-dose colchicine 0.5-1.0 mg daily may be used. Other recommendations included parenteral or oral corticosteroid for acute CPP arthritis in those unresponsive or unsuited to other measures, and lowdose corticosteroid, methotrexate or hydroxychloroquine for chronic inflammatory arthritis with CPPD. Asymptomatic CPPD requires no treatment. Strength of recommendations varies from 79% to 95%. Conclusion: Nine key recommendations for management of CPP crystal associated arthritis were developed using both research evidence and expert consensus. Strength of recommendations was provided to assist the application of these recommendations. Source

Purpose: To evaluate the efficacy and safety of first-line single-agent cetuximab in fit elderly patients with metastatic colorectal cancer, as well as potential molecular predictive factors for efficacy. Patients and methods: Patients aged 70 or older with metastatic CRC without criteria for frailty and no prior treatment for advanced disease were treated with single-agent cetuximab 400mg/m2 followed by weekly 250mg/m2 until disease progression or unacceptable toxicity. Results: Forty-one patients were included. Two patients achieved a complete response and 4 patients had a partial response for an overall response rate of 14.6%. Fifteen patients (36.6%) remained stable. Median time to progression was 2.9 months and median overall survival 11.1 months despite two-third of patients received chemotherapy at progression. Forty-five percent of EGFR gene copy number positive patients by FISH were progression-free at 12 weeks, in contrast with 12% of FISH negative patients (p= 0.04). Grade 3 skin toxicity was reported in 5 patients (12.2%). Hypersensitivity infusion reactions were not reported and there were no toxic deaths. Conclusion: Cetuximab is a safe monoclonal antibody with moderate activity in first-line metastatic colorectal cancer, but the present study does not support the use of cetuximab as single-agent in first-line fit elderly patients with metastatic CRC. © 2009 Elsevier Ireland Ltd.

This 24-week, open, single-arm, prospective, multicenter study evaluated the effects of conversion from ciclosporin to Tacrolimus QD in adult kidney transplant patients. Stable patients receiving ciclosporin were converted to Tacrolimus QD at 0.1 mg/kg/day. Relative change in renal function (primary endpoint) was assessed using estimated creatinine clearance (eCrCl) with a noninferiority margin set at -10%. A total of 346 patients were enrolled; and 301 patients were treated per protocol (PPS) in the hyperlipidemia (n = 42), hypertrichosis (n = 106), hypertension (n = 77) and gingival hyperplasia (n = 76) groups. Relative change in eCrCl was -0.6% in all PPS patients (95% CI, -2.2; 0.9) and -5.3% in the hyperlipidemia (CI, -9.59; -0.97), 0.9% in the hypertrichosis (CI, -2.59; 4.45), -0.1% in the hypertension (CI, -3.8; 3.68), and -1% in the gingival hyperplasia groups (CI, -4.63; 2.65) (PPS), meeting noninferiority criteria. There was no acute rejection. Decreases in serum lipids and blood pressure were moderate but without meaningful change in the number of treatment medications. Substantial decreases in severity of ciclosporin-related cosmetic side effects were evident from investigator and patient self-report of symptoms. Renal function remained stable after conversion to Tacrolimus QD. The effect of conversion on cardiovascular parameters was not clinically meaningful, however, marked improvement in ciclosporin-related cosmetic side effects was observed. © 2011 European Society for Organ Transplantation.
