[Title]: Assessment of fludarabine plus cyclophosphamide for patients with chronic lymphocytic leukaemia (the LRF CLL4 Trial): a randomised controlled trial.
[Abstract]: BACKGROUND: Previous studies of patients with chronic lymphocytic leukaemia reported high response rates to fludarabine combined with cyclophosphamide. We aimed to establish whether this treatment combination provided greater survival benefit than did chlorambucil or fludarabine. METHODS: 777 patients with chronic lymphocytic leukaemia requiring treatment were randomly assigned to fludarabine (n=194) or fludarabine plus cyclophosphamide (196) for six courses, or chlorambucil (387) for 12 courses. The primary endpoint was overall survival, with secondary endpoints of response rates, progression-free survival, toxic effects, and quality of life. Analysis was by intention to treat. This study is registered as an International Standard Randomised Controlled Trial, number NCT 58585610. FINDINGS: There was no significant difference in overall survival between patients given fludarabine plus cyclophosphamide, fludarabine, or chlorambucil. Complete and overall response rates were better with fludarabine plus cyclophosphamide than with fludarabine (complete response rate 38%vs 15%, respectively; overall response rate 94%vs 80%, respectively; p&lt;0.0001 for both comparisons), which were in turn better than with chlorambucil (complete response rate 7%, overall response rate 72%; p=0.006 and 0.04, respectively). Progression-free survival at 5 years was significantly better with fludarabine plus cyclophosphamide (36%) than with fludarabine (10%) or chlorambucil (10%; p&lt;0.00005). Fludarabine plus cyclophosphamide was the best combination for all ages, including patients older than 70 years, and in prognostic groups defined by immunoglobulin heavy chain gene (V(H)) mutation status and cytogenetics, which were tested in 533 and 579 cases, respectively. Patients had more neutropenia and days in hospital with fludarabine plus cyclophosphamide, or fludarabine, than with chlorambucil. There was less haemolytic anaemia with fludarabine plus cyclophosphamide (5%) than with fludarabine (11%) or chlorambucil (12%). Quality of life was better for responders, but preliminary analyses showed no significant difference between treatments. A meta-analysis of these data and those of two published phase III trials showed a consistent benefit for the fludarabine plus cyclophosphamide regimen in terms of progression-free survival. INTERPRETATION: Fludarabine plus cyclophosphamide should now become the standard treatment for chronic lymphocytic leukaemia and the basis for new protocols that incorporate monoclonal antibodies.

[Title]: Safety of celecoxib in patients with cutaneous reactions due to ASA-NSAIDs intolerance.
[Abstract]: BACKGROUND: Pseudo-allergic reactions against aspirin (ASA) and non-steroidal anti-inflammatory drugs (NSAIDs) are quite frequent. OBJECTIVE: Our aim was to determine tolerance of Celecoxib, a selective inhibitor of cyclooxygenase-2 (Cox-2), by oral challenge test in patients who showed skin reactions (diffuse erythema or urticaria/angioedema) after taking ASA and/or NSAIDs. METHODS: The oral challenge test was carried out in single-blind on 86 patients treated with a 200 mg cumulative dose of Celebrex, administered in 3 or 4 visits at 48-72 hours interval. RESULTS: Only 4 patients showed mild skin reactions. In addition, we observed 37 patients with osteoarthrosis taking a 200-400 mg/day dose of Celebrex 5-6 times a week, over a period of 75 days. At day 36, we observed in a single patient urticarial phenomena appeared on the chest and the back. CONCLUSIONS: Our study proves therefore Celecoxib safety on a 72-hour observation period.

[Title]: Modulation of arterial reactivity using amlodipine and atorvastatin measured by ultrasound examination (MARGAUX).
[Abstract]: OBJECTIVE: To evaluate the effect of the calcium channel blocker amlodipine on endothelial function in normotensive patients with coronary disease taking concomitant atorvastatin therapy. METHODS AND RESULTS: Atorvastatin was titrated (10-80 mg/day) to maintain LDL-C&lt;2.5 mmol/L and patients were randomized to receive amlodipine (5-10mg/day, n=64) or placebo (n=70) for 12 months. Brachial artery flow-mediated vasodilation (FMD) was assessed using vascular ultrasound. Inflammatory markers were also measured. At 12 months there was a significant decrease in mean low-density lipoprotein cholesterol (LDL-C) (4.4-2.1 mmol/L, P&lt;0.0001), high-sensitivity C-reactive protein (hsCRP) (3.8-2.3mg/L, P&lt;0.0001) and soluble vascular cell adhesion molecule-1 (sVCAM-1) (710-665 ng/mL, P&lt;0.0001) for all patients, compared with baseline. Amlodipine was associated with a mean blood pressure reduction of 8/3 mm Hg (P&lt;0.0001) whereas patients on placebo had no significant change. In the atorvastatin-placebo group, mean FMD increased (7.3-9.5%, P&lt;0.05) with no change in nitroglycerin-mediated dilation. No further benefit on FMD or inflammatory markers was observed with the addition of amlodipine. CONCLUSIONS: Intensive reduction of LDL-C with atorvastatin improves endothelium-dependent vasodilation and reduces markers of inflammation in patients with coronary disease. Amlodipine was not associated with a significant additional benefit on these variables.

[Title]: Neuropathy in multiple myeloma treated with thalidomide: a prospective study.
[Abstract]: BACKGROUND: Thalidomide is effective as a first-line therapy for the treatment of multiple myeloma (MM), but its use is limited by peripheral neurotoxicity. OBJECTIVE: To study the occurrence of both myeloma-related neuropathy and thalidomide-induced neuropathy in 31 patients with newly diagnosed MM. METHODS: Clinical and electrophysiologic examinations were performed in 31 patients with newly diagnosed MM before and after 4 months of therapy with thalidomide (200 mg/day, total dose: 21 g) aimed at debulking MM, before autologous transplantation. After transplantation, the patients took thalidomide, 200 mg/day for another 3 months (total dose over three months: 18 g) and then underwent a final clinical and electrophysiologic checkup. RESULTS: At baseline, four patients presented a mild sensorimotor peripheral neuropathy related to MM, which tended to worsen slightly during treatment with thalidomide. At the end of treatment, 83% of the patients had clinical and electrophysiologic evidence of a mild sensory rather than motor, axonal, length-dependent polyneuropathy, whereas 100% of the patients showed improvement to the basic pathology (&gt;or=partial response). CONCLUSIONS: Peripheral neuropathy, sometimes subclinical, and mild in our patients, is a common, early side effect of thalidomide therapy. The high doses (21 g) used in all patients for a relatively short time (4 months) rule out any correlations between neuropathy, total dose, and duration of treatment.

[Title]: Predictors of therapeutic response to beta-blockers in patients with heart failure in Taiwan.
[Abstract]: BACKGROUND/PURPOSE: Chinese are more sensitive to beta-blockers than Caucasians. However, data regarding beta-blocker therapy in heart failure (HF) patients in Taiwan are lacking. We aimed to evaluate the improvement of left ventricular function and the potential predictors of response to beta-blocker therapy in Taiwanese HF patients. METHODS: We enrolled 34 HF patients with baseline left ventricular ejection fraction (LVEF) &lt;/= 40%. Beta-blockers were titrated up to the maximum tolerable dose. LVEF prior to beta-blocker usage and at the stable dose were obtained. We also sequenced the entire gene encoding beta1-adrenoceptor to assess the relationships between LVEF improvement and gene polymorphisms. RESULTS: Beta-blocker therapy (25 +/- 22 months) with a mean stable dose of 12 +/- 8 mg carvedilol/day significantly improved LVEF (from 28 +/- 8% to 40 +/- 15%, p &lt; 0.001). Stepwise multiple linear regression analysis identified dilated cardiomyopathy (beta = 18.32, p = 0.0004), baseline LVEF (beta = -0.85, p = 0.0020), use of amiodarone (beta = -22.58, p = 0.0034) and square of digoxin dose (beta = -314.25, p = 0.0059) at stable beta-blocker dose as independent predictors of LVEF improvement, where beta is the estimated regression coefficient. We did not find any novel variant of beta1-adrenoceptor gene other than those previously reported at codons 49 and 389, with the allele distributions similar to those found in Caucasians, and these polymorphisms did not imply therapeutic response to beta-blocker. CONCLUSION: We demonstrated the therapeutic effects of beta-blockers in Taiwanese HF patients with a dose lower than what has been reported in Western people. Moreover, patients with the etiology of dilated cardiomyopathy or lower baseline LVEF predicted a greater LVEF improvement. The beta1-adrenoceptor gene polymorphisms were not responsible for the difference in sensitivity to beta-blockers in this Taiwanese population.

[Title]: A novel mutation pattern emerging during lamivudine treatment shows cross-resistance to adefovir dipivoxil treatment.
[Abstract]: AIMS: This study was conducted to clarify the resistance profile of a novel mutation pattern emerging during lamivudine (3TC) therapy and showing cross-resistance to adefovir dipivoxil (ADV) in a patient with chronic hepatitis B. METHODS AND RESULTS: Successful suppression of hepatitis B virus (HBV) replication by sequential therapy of 9 MU thrice weekly interferon (IFN) and 3TC was followed by genotypical resistance detected at month 28 of therapy (month 19 of lamivudine treatment). ADV was added to 3TC therapy on month 44 of antiviral treatment. Neither alanine aminotransferase normalization nor a stable decrease in HBV viral load was observed, although ADV was used for more than 40 months. The HBV pol region was amplified from serum samples obtained before and after ADV treatment. The complete genome was cloned into a TA vector. PCR products and 7-10 clones from each cloned vector were sequenced. A novel mutation, A181S, in the reverse transcriptase gene leading to a conversion of W172C in the overlapping surface antigen gene was detected along with a M2041 mutation. The complete genome comprising the A181S+M2041 pattern was cloned into an expression vector and its in vitro susceptibility to 3TC, ADV, tenofovir (PMPA), clevudine (L-FMAU) and emtricitabine (FTC) were determined in transiently transfected Huh7 cells. This mutation pattern displayed more than 1000-fold resistance to the nucleoside analogues 3TC and FTC and approximately sixfold resistance to L-FMAU, while it confers 28.23- and 5.57-fold resistance for the nucleotide analogues ADV and PMPA, respectively. CONCLUSION: A new mutation pattern, A181S+M2041, arising under lamivudine treatment confers cross-resistance to ADV both in vivo and in vitro.

[Title]: Phase 2 study of pegylated liposomal doxorubicin in combination with interleukin-12 for AIDS-related Kaposi sarcoma.
[Abstract]: Thirty-six patients with AIDS-associated Kaposi sarcoma (KS) requiring chemotherapy were treated for six 3-week cycles of pegylated liposomal doxorubicin (20 mg/m(2)) plus interleukin-12 (IL-12; 300 ng/kg subcutaneously twice weekly), followed by 500 ng/kg subcutaneous IL-12 twice weekly for up to 3 years. All received highly active antiretroviral therapy (HAART). Twenty-two had poor-prognosis KS (T(1)S(1)). Thirty patients had a major response, including 9 with complete response, yielding an 83.3% major response rate (95% confidence interval: 67.2%-93.6%). Median time to first response was 2 cycles. Median progression was not reached at median potential follow-up of 46.9 months. Of 27 patients with residual disease when starting maintenance IL-12, 15 had a new major response compared with this new baseline. The regimen was overall well tolerated; principal toxicities were neutropenia, anemia, transaminitis, and neuropsychiatric toxicity. Patients had increases in serum IL-12, interferon gamma, and inducible protein-10 (IP-10), and these remained increased at weeks 18 and 34. The regimen of IL-12 plus liposomal doxorubicin yielded rapid tumor responses and a high response rate in patients with AIDS-KS receiving HAART, and responses were sustained on IL-12 maintenance therapy. A randomized trial of IL-12 in this setting may be warranted. This study is registered at (http://www.clinicaltrials.gov) as no. NCT00020449.

[Title]: A randomized, placebo-controlled trial of citicoline add-on therapy in outpatients with bipolar disorder and cocaine dependence.
[Abstract]: INTRODUCTION: Bipolar disorder is associated with the highest rates of substance abuse of any psychiatric disorder. Cocaine use is particularly common in patients with bipolar disorder. Both cocaine use and bipolar disorder are associated with mood symptoms and cognitive impairment. Therefore, treatments that stabilize mood, improve cognition, and reduce cocaine use would be useful. Citicoline modulates phospholipids metabolism and neurotransmitter levels and appears to improve cognition in some central nervous system disorders. A 12-week, randomized, placebo-controlled, parallel-group, add-on, proof-of-concept trial of citicoline was conducted in 44 outpatients with a history of mania or hypomania and cocaine dependence. The primary aim was to examine memory, but mood and cocaine use were also assessed. METHOD: Participants were evaluated with a structured diagnostic interview; Inventory of Depressive Symptomatology-Self-Report, Young Mania Rating Scale, and Rey Auditory Verbal Learning Test. Cocaine use was assessed with urine drug screens. Data were analyzed using mixed-model analysis of covariance, generalized estimating equations, and logistic regression analyses that used all of the available data. RESULTS: A significant group effect (P = 0.006) favoring citicoline was observed on the Rey Auditory Verbal Learning Test alternative word list. No significant between-group differences were found on the Inventory of Depressive Symptomatology-Self-Report or Young Mania Rating Scale. The citicoline group had a significantly lower probability of a cocaine-positive urine at exit (P = 0.026). The covariate-adjusted odds ratio estimate was 6.41, suggesting that those who took placebo had 6.41-times higher odds of testing positive for cocaine at exit than those who took citicoline. Citicoline was well tolerated, with no participants to our knowledge discontinuing because of medication side effects. CONCLUSIONS: The use of citicoline was associated with improvement relative to placebo in some aspects of declarative memory and cocaine use, but not mood. The findings are promising and suggest that larger trials of citicoline are warranted.

[Title]: A randomized, flexible-dose, quasi-naturalistic comparison of quetiapine, risperidone, and olanzapine in the short-term treatment of schizophrenia: the QUERISOLA trial.
[Abstract]: This was a randomized, flexible-dose, rater-blind, parallel-group, quasi-naturalistic trial comparing the efficacy, safety, and tolerability of quetiapine, risperidone, and olanzapine in patients with schizophrenia hospitalized for severe psychotic symptoms. Seventy-five patients were randomized to quetiapine (n=25), risperidone (n=25), or olanzapine (n=25). Mean doses at Week 8 were: 590.0 mg/day quetiapine; 5.1 mg/day risperidone; 15.1 mg/day olanzapine. Four quetiapine, five risperidone, and five olanzapine patients discontinued prior to Week 8. There were no significant differences between groups in the primary efficacy measures of improvement from baseline in Positive and Negative Syndrome Scale (PANSS) total score at Week 8 in the per protocol (PP) population and the number of completers who experienced >or=40% improvement on the same scale. PP and intent-to-treat analyses showed significant improvement from baseline in each component of a PANSS-derived battery, without significant differences between treatments. No quetiapine patients, one risperidone, and four olanzapine patients reported an adverse event (AE) of moderate intensity; no severe AEs were reported. A linear mixed model for repeated measures showed an effect of treatment on body weight, with significant differences favoring quetiapine over risperidone and olanzapine. Simpson-Angus Scale scores were significantly worse with risperidone compared with both olanzapine and quetiapine at Week 3 and compared with quetiapine thereafter. Use of concomitant medications for anxiety or tension was significantly less frequent with quetiapine. In conclusion, quetiapine, risperidone, and olanzapine have similar efficacy in schizophrenia, but there are drug-specific differences for some AEs and in the use of concomitant medication that differentiate these agents.
