Scleritis after proton therapy in uveal melanoma [Skleritis nach Protonentherapie bei Aderhautmelanom]

BACKGROUND: Sclera is a very radioresistant tissue and scleritis after proton therapy has not been described so far. HISTORY AND SIGNS: Four female patients, aged between 31 and 74 years, were treated with proton therapy for uveal melanoma (height range: 2.2 - 3.5 mm), located in the macula, the superior equator and 2 in the ciliary body. All patients had a history of a previous or active inflammatory disease and developed scleritis after radiotherapy. THERAPY AND OUTCOME: Two patients had infectious scleritis and were treated with adequate antibiotic therapy. After systemic corticotherapy, 3 patients recovered completely; the remaining patient was managed with additional immunosuppressive treatment as well as a conjunctival and scleral graft, but has not become pain free yet. CONCLUSION: Scleritis is a possible complication after proton therapy, probably on an ischemic basis, where there is a predisposing factor such as inflammatory systemic disease.

Ambulatory blood pressure monitoring to assess antihypertensive therapy in private practice

Non-invasive ambulatory blood pressure monitoring has proved to be very useful in evaluating hypertensive patients. However, most previous studies were performed in specialised centres. Here the results of two trials are presented in which private physicians used ambulatory BP monitoring to assess the efficacy of antihypertensive drugs. The results were very similar to those observed previously in specialised clinics. In the individual patient, the level of ambulatory recorded pressure could not be predicted based on BP readings taken at the doctor's office. Also, the BP response to antihypertensive therapy was more reproducible when evaluated by ambulatory BP monitoring than by the doctor. Thus, the use of noninvasive ambulatory BP monitoring is also very appropriate in everyday practice for the management of hypertensive patients.

Mediastinal reinforcement after induction therapy and pneumonectomy: comparison of intercostal muscle versus diaphragm flaps.

OBJECTIVE: Prospective non-randomised comparison of full-thickness pedicled diaphragm flap with intercostal muscle flap in terms of morbidity and efficiency for bronchial stump coverage after induction therapy followed by pneumonectomy for non-small cell lung cancer (NSCLC). METHODS: Between 1996 and 1998, a consecutive series of 26 patients underwent pneumonectomy following induction therapy. Half of the patients underwent mediastinal reinforcement by use of a pedicled intercostal muscle flap (IF) and half of the patients by use of a pedicled full-thickness diaphragm muscle flap (DF). Patients in both groups were matched according to age, gender, side of pneumonectomy and stage of NSCLC. Postoperative morbidity and mortality were recorded. Six months follow-up including physical examination and pulmonary function testing was performed to examine the incidence of bronchial stump fistulae, gastro-esophageal disorders or chest wall complaints. RESULTS: There was no 30-day mortality in both groups. Complications were observed in one of 13 patients after IF and five of 13 after DF including pneumonia in two (one IF and one DF), visceral herniations in three (DF) and bronchopleural fistula in one patient (DF). There were no symptoms of gastro-esophageal reflux disease (GERD). Postoperative pulmonary function testing revealed no significant differences between the two groups. CONCLUSIONS: Pedicled intercostal and diaphragmatic muscle flaps are both valuable and effective tools for prophylactic mediastinal reinforcement following induction therapy and pneumonectomy. In our series of patients, IF seemed to be associated with a smaller operation-related morbidity than DF, although the difference was not significant. Pedicled full-thickness diaphragmatic flaps may be indicated after induction therapy and extended pneumonectomy with pericardial resection in order to cover the stump and close the pericardial defect since they do not adversely influence pulmonary function.

An EORTC Phase II study of caspofungin as first-line therapy of invasive aspergillosis in haematological patients.

OBJECTIVES: Caspofungin was evaluated as first-line monotherapy of invasive aspergillosis (IA) in patients with haematological malignancies and undergoing autologous transplants. METHODS: Adults with proven or probable IA, defined strictly according to EORTC-MSG criteria, were eligible. Those with possible IA were enrolled, but were not evaluable for efficacy unless upgraded to proven/probable disease within 7 days of registration based on investigations performed within 48 h after enrolment. Caspofungin dosage was 70 mg (day 1) followed by 50 mg/day. The primary endpoint was the proportion of patients with complete or partial response at the end of caspofungin therapy in the modified intention to treat (MITT) group; secondary endpoints were response and survival at day 84 and safety. RESULTS: In the MITT group (n = 61), 75% of patients had cancer not in remission (relapsing or refractory), 85% were neutropenic at enrolment and 49% had a Karnofsky score of < or =50. At end of treatment, 1 and 19 patients had complete and partial response, respectively [success rate 33% (20/61)], 9 (15%) achieved stabilization and 31 (51%) had disease progression. One patient was not evaluable. The 6 and 12 week survival rates were 66% (40/61) and 53% (32/60), respectively. Baseline characteristics associated with survival at day 84 were an underlying disease in remission (not relapsing or refractory) and Karnofsky score. Recovery from neutropenia at the end of treatment was also significantly associated with survival. No serious drug-related adverse events or discontinuations due to drug-related adverse events were observed. CONCLUSIONS: Caspofungin provided an observed response rate compatible with the null hypothesis of a true response rate of < or =35%. Underlying disease-related factors had a major impact on results.

Impact of etanercept-methotrexate therapy on patient-reported outcomes in rheumatoid arthritis patients with up to 12 months of symptoms.

Background/Purpose: Patient-reported outcomes (PROs) in patients with rheumatoid arthritis (RA) are critical in evaluating RA treatment effects on function and health-related quality of life (HR-QoL). Significant improvement in PROs has been reported in RA studies of biologic agents, including etanercept (ETN), but most studies have been conducted in patients with established disease. In addition to assessing treatment effects in early RA, there is interest in therapeutic strategies that allow dose reduction or withdrawal of biologic therapy (biologic-free) after induction of response. The PRIZE trial is an ongoing, 3-period study to evaluate the efficacy of combined ETN and methotrexate (MTX) therapy in patients with early, moderate-to-severe RA and to assess whether efficacy (remission) can be maintained with ETN dose reduction or biologic-free (Period 2) or drug-free (Period 3). Herein we report PROs associated with ETN 50 mg QW plus MTX (ETN50/MTX) therapy administered for 52 wks in Period 1 (induction) of the PRIZE trial. Methods: In Period 1, MTX- and biologic-naı‥ve patients with early, active RA (symptom onset 12 mo from enrollment; DAS28 _3.2) received open-label ETN50/MTX for 52 wks. The starting dose of MTX was 10 mg QW; at the discretion of the investigator, titration was permitted up to a maximum of 25 mg QW to achieve remission. Corticosteroid boosts were administered to patients not achieving low disease state at wks 13 and 26, unless contraindicated or not tolerated. PROs were assessed using the Health Assessment Questionnaire (HAQ) total score; Patient Acceptable Symptom State (PASS); EuroQol-5 Dimensions (EQ-5D) total index; Short Form Health Survey (SF-36); Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue; Work Instability Scale for Rheumatoid Arthritis (RAWIS); and Work Productivity and Activity Impairment Questionnaire: Rheumatoid Arthritis (WPAI:RA). Results: A total of 306 patients received treatment in Period 1 (mITT population); 222 (73%) patients completed the period. The majority of patients were female (70%), with a mean age of 50 y, mean DAS28 of 6.0 (median, 6.0), and duration of disease symptoms from onset of 6.5 months (median, 6.3 mo). Significant and clinically meaningful improvements in PROs, including in HAQ, EQ-5D, SF-36, and FACIT-Fatigue, were demonstrated with ETN50/MTX therapy from baseline to the final on therapy visit (Table; P_0.0001). Similar improvements were observed in all dimensions of RA-WIS and WPAI:RA (Table; P_0.0001). Conclusion: Combination therapy with ETN50/MTX for 52 wks in patients with _12 mo of symptomatic, active RA resulted in significant, clinically important improvements in measures of physical function, including normal HAQ (66.6% of patients), HR-QoL, fatigue, and work productivity. These outcomes are consistent with those reported in prior studies in patients with more established disease.

Peri-operative management of antiplatelet therapy in patients with coronary artery disease. Joint position paper by members of the working group on Perioperative Haemostasis of the Society on Thrombosis and Haemostasis Research (GTH), the working group on Perioperative Coagulation of the Austrian Society for Anesthesiology, Resuscitation and Intensive Care (ÖGARI) and the Working Group Thrombosis of the European Society for Cardiology (ESC).

An increasing number of patients suffering from cardiovascular disease, especially coronary artery disease (CAD), are treated with aspirin and/or clopidogrel for the prevention of major adverse events. Unfortunately, there are no specific, widely accepted recommendations for the perioperative management of patients receiving antiplatelet therapy. Therefore, members of the Perioperative Haemostasis Group of the Society on Thrombosis and Haemostasis Research (GTH), the Perioperative Coagulation Group of the Austrian Society for Anesthesiology, Reanimation and Intensive Care (ÖGARI) and the Working Group Thrombosis of the European Society of Cardiology (ESC) have created this consensus position paper to provide clear recommendations on the perioperative use of anti-platelet agents (specifically with semi-urgent and urgent surgery), strongly supporting a multidisciplinary approach to optimize the treatment of individual patients with coronary artery disease who need major cardiac and non-cardiac surgery. With planned surgery, drug eluting stents (DES) should not be used unless surgery can be delayed for ≥12 months after DES implantation. If surgery cannot be delayed, surgical revascularisation, bare-metal stents or pure balloon angioplasty should be considered. During ongoing antiplatelet therapy, elective surgery should be delayed for the recommended duration of treatment. In patients with semi-urgent surgery, the decision to prematurely stop one or both antiplatelet agents (at least 5 days pre-operatively) has to be taken after multidisciplinary consultation, evaluating the individual thrombotic and bleeding risk. Urgently needed surgery has to take place under full antiplatelet therapy despite the increased bleeding risk. A multidisciplinary approach for optimal antithrombotic and haemostatic patient management is thus mandatory.

Health technology assessment in evolution - focal therapy in localised prostate cancer.

Focal therapy in prostate cancer aims to treat only the part of the gland harboring clinically significant disease while preserving the rest of the tissue. This approach may substantially reduce treatment-related toxicity without compromising disease control outcomes. Short- to medium-term functional and oncological results in prospective interventional studies are promising, but comparative effectiveness research against standard of care is required to incorporate focal therapy among standard options. In this review, we discuss the actual stage of assessment and results of sources of energy commonly used to deliver focal therapy. We also provide our viewpoint on how the field will evolve in the near future.

Nighttime blood pressure: a target for therapy?

Ambulatory blood pressure (BP) monitoring is increasingly used in the evaluation of hypertensive patients. The ability to monitor BP throughout the day and night allows the detection of abnormal nocturnal BP patterns, the most common being a "nondipping" pattern, which is associated with increased cardiovascular risk; its correction appears to have a positive impact on cardiovascular outcome. Antihypertensive treatment should be individually adjusted to control BP during both daytime and nighttime. However, drug-induced lowering of nocturnal BP, if excessive, could amplify the morning BP surge in patients with daytime BP elevation, increasing the risk of developing a cardiovascular event. Ambulatory BP monitoring therefore represents a unique tool to establish the most appropriate antihypertensive drug regimen for the individual patient.

Combination of androgen deprivation therapy and radiotherapy for localized prostate cancer in the contemporary era.

Currently, androgen deprivation therapy (ADT) has a well-defined role when administered together with radiotherapy (RT): neo-adjuvant and concurrent combination for intermediate risk-disease and adjuvant therapy for high risk disease. Evidence of this association was generated by randomized trials designed and led approximately 30 years ago; thus the question which arises is how relevant and portable are these data in our current clinical practice? In the present review, we examine the pitfalls of these published randomized controlled trials, their relevance to present daily clinics, where high-dose external beam RT or brachytherapy is applied, as well as the adoption of ADT in patients with concomitant cardiovascular disorders.

Hypothyroid myopathy as a complication of interferon alpha therapy for chronic hepatitis C virus infection.

Interferon alpha (IFN-alpha) therapy is associated with a number of immunological side-effects, including autoimmune diseases and a 10% prevalence of thyroiditis. Hepatitis C virus (HCV) infection itself predisposes to autoimmune phenomena including hypothyroidism and myositis. The development of clinical hypothyroidism in the presence of positive thyroid antibodies in patients infected with HCV and treated with IFN-alpha suggests a possible association between the viral disease and the therapy. HCV infection may predispose to autoimmune thyroid disease and IFN-alpha therapy may secondarily lead to the development of thyroid dysfunctions. We report the single case of a female patient who developed a severe proximal myopathy in conjunction with primary hypothyroidism (Hoffmann's syndrome) secondarily to IFN-alpha therapy for HCV infection. This case highlights the need for careful clinical and biological monitoring for potential side-effects in such patients.

Effect of atazanavir versus other protease inhibitor-containing antiretroviral therapy on endothelial function in HIV-infected persons: randomised controlled trial.

OBJECTIVE: Impaired endothelial function was demonstrated in HIV-infected persons on protease inhibitor (PI)-containing antiretroviral therapy, probably due to altered lipid metabolism. Atazanavir is a PI causing less atherogenic lipoprotein changes. This study determined whether endothelial function improves after switching from other PI to atazanavir. DESIGN: Randomised, observer-blind, treatment-controlled trial. SETTING: Three university-based outpatient clinics. PATIENTS: 39 HIV-infected persons with suppressed viral replication on PI-containing regimens and fasting low-density lipoprotein (LDL)-cholesterol greater than 3 mmol/l. INTERVENTION: Patients were randomly assigned to continue the current PI or change to unboosted atazanavir. MAIN OUTCOME MEASURES: Endpoints at week 24 were endothelial function assessed by flow-mediated dilation (FMD) of the brachial artery, lipid profiles and serum inflammation and oxidative stress parameters. RESULTS: Baseline characteristics and mean FMD values of the two treatment groups were comparable (3.9% (SD 1.8) on atazanavir versus 4.0% (SD 1.5) in controls). After 24 weeks' treatment, FMD decreased to 3.3% (SD 1.4) and 3.4% (SD 1.7), respectively (all p = ns). Total cholesterol improved in both groups (p<0.0001 and p = 0.01, respectively) but changes were more pronounced on atazanavir (p = 0.05, changes between groups). High-density lipoprotein and triglyceride levels improved on atazanavir (p = 0.03 and p = 0.003, respectively) but not in controls. Serum inflammatory and oxidative stress parameters did not change; oxidised LDL improved significantly in the atazanavir group. CONCLUSIONS: The switch from another PI to atazanavir in treatment-experienced patients did not result in improvement of endothelial function despite significantly improved serum lipids. Atherogenic lipid profiles and direct effects of antiretroviral drugs on the endothelium may affect vascular function. Trial registration number: NCT00447070.

Dynamic impacts of the inhibition of the molecular chaperone hsp90 on the T-cell proteome have implications for anti-cancer therapy.

The molecular chaperone Hsp90-dependent proteome represents a complex protein network of critical biological and medical relevance. Known to associate with proteins with a broad variety of functions termed clients, Hsp90 maintains key essential and oncogenic signalling pathways. Consequently, Hsp90 inhibitors are being tested as anti-cancer drugs. Using an integrated systematic approach to analyse the effects of Hsp90 inhibition in T-cells, we quantified differential changes in the Hsp90-dependent proteome, Hsp90 interactome, and a selection of the transcriptome. Kinetic behaviours in the Hsp90-dependent proteome were assessed using a novel pulse-chase strategy (Fierro-Monti et al., accompanying article), detecting effects on both protein stability and synthesis. Global and specific dynamic impacts, including proteostatic responses, are due to direct inhibition of Hsp90 as well as indirect effects. As a result, a decrease was detected in most proteins that changed their levels, including known Hsp90 clients. Most likely, consequences of the role of Hsp90 in gene expression determined a global reduction in net de novo protein synthesis. This decrease appeared to be greater in magnitude than a concomitantly observed global increase in protein decay rates. Several novel putative Hsp90 clients were validated, and interestingly, protein families with critical functions, particularly the Hsp90 family and cofactors themselves as well as protein kinases, displayed strongly increased decay rates due to Hsp90 inhibitor treatment. Remarkably, an upsurge in survival pathways, involving molecular chaperones and several oncoproteins, and decreased levels of some tumour suppressors, have implications for anti-cancer therapy with Hsp90 inhibitors. The diversity of global effects may represent a paradigm of mechanisms that are operating to shield cells from proteotoxic stress, by promoting pro-survival and anti-proliferative functions. Data are available via ProteomeXchange with identifier PXD000537.

Cognitive behavioural therapy for obesity and binge eating associated to antipsychotic drugs

Background and Aims: Overweight, obesity and binge eating disorder are commonly reported in persons with severe mental disorders. Particularly, antipsychotic drugs (AP) induce weight gain in up to half of the patients. The aim of the present study is to confirm a previous study results on a larger sample of patients, to assess the impact of the interventions on other relevant dimensions of eating and weight related cognitions as well as to assess potential clinical indicators of outcomes such as AP drug, concomitant treatment with lithium or carbamazepine, psychiatric diagnostic, binge eating and severity of cognitive distortions. Method: A controlled study (12-week CBT vs. B N E) was carried out on 99 patients treated with an AP and who have gained weight following this treatment. Binge eating symptomatology, eating and weight-related cognitions, as well as weight and body mass index were assessed before treatment, at 12 weeks and at 24 weeks. Results: The findings confirms usefulness and effectiveness of the proposed CBT program on the treatment of binge symptomatology, cognitive distortions and obesity in patients treated with AP. Reduction of binge symptoms and maladapted cognitions appeared early, whereas the effect on weight appeared later during the follow up observation. No differences on outcomes were found across pharmacotherapy characteristics, diagnostic categories, binge eating nor severity of cognitive distortions. Conclusion: The proposed CBT treatment is useful for patients suffering from weight gain associated with AP treatments indeed when a concomitant treatment with lithium or valproate was given.
