Effects of pumpkin seed in men with lower urinary tract symptoms due to benign prostatic hyperplasia in the one-year, randomized, placebo-controlled GRANU study.

INTRODUCTION: The German Research Activities on Natural Urologicals (GRANU) study was a randomized, partially blinded, placebo-controlled, parallel-group trial that investigated the efficacy of pumpkin seed in men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH/LUTS). SUBJECTS AND METHODS: A total of 1,431 men (50-80 years) with BPH/LUTS were randomly assigned to either pumpkin seed (5 g b.i.d.), capsules with pumpkin seed extract (500 mg b.i.d.) or matching placebo. The primary response criterion was a decrease in International Prostate Symptom Score (IPSS) of ≥5 points from baseline after 12 months. Secondary outcome measures included IPSS-related quality of life, IPSS single items and diary-recorded nocturia. RESULTS: After 12 months, the response rate (intention-to-treat/last-observation-carried-forward approach) did not differ between pumpkin seed extract and placebo. In the case of pumpkin seed (responders: 58.5%), the difference compared with placebo (responders: 47.3%) was descriptively significant. The study products were well tolerated. Overall, in men with BPH, 12 months of treatment with pumpkin seed led to a clinically relevant reduction in IPSS compared with placebo. CONCLUSION: In order to fully justify a recommendation for the use of pumpkin seed to treat moderate LUTS, these findings need to be substantiated in a confirmatory study or systematic review.

Comparisons of health status scores with MRC grades in COPD: implications for the GOLD 2011 classification.

The 2011 Global Initiative for Chronic Obstructive Lung Disease (GOLD) strategy document recommends assessment of chronic obstructive pulmonary disease (COPD) using symptoms and future exacerbation risk, employing two score cut-points: COPD Assessment Test (CAT) score ≥ 10 or modified Medical Research Council dyspnoea scale (mMRC) grade ≥ 2. To explore the equivalence of these two symptom cut-points, the relationship between the CAT and the mMRC and St George's Respiratory Questionnaire (SGRQ), the Short-form Health Survey and the Functional Assessment of Chronic Illness Therapy Fatigue scores were retrospectively analysed using a primary care dataset. Data from 1817 patients (mean ± SD forced expiratory volume in 1 s 1.6 ± 0.6 L) showed a significant association between mMRC grades and all health status scores (ANOVA p<0.0001). mMRC grade 1 was associated with significant levels of health status impairment (SGRQ 39.4 ± 15.5 and CAT 15.7 ± 7.0); even patients with mMRC grade 0 had modestly elevated scores (SGRQ 28.5 ± 15.1 and CAT 11.7 ± 6.8). An mMRC grading ≥ 2 categorised 57.2% patients with low symptom (groups A and C) versus 17.2% with the CAT. Using the mMRC cut-point (≥ 1) resulted in similar GOLD group categorisations as the CAT (18.9%). The mMRC showed a clear relationship with health status scores; even low mMRC grades were associated with health status impairment. Cut-points of mMRC grade ≥ 1 and CAT score ≥ 10 were approximately equivalent in determining low-symptom patients. The GOLD assessment framework may require refinement.

Patient-centred assessment of COPD in primary care: experience from a cross-sectional study of health-related quality of life in Europe.

BACKGROUND: Most patients with chronic obstructive pulmonary disease (COPD) in Europe are treated in primary care, but perceptions on what guides primary care physicians (PCPs) in managing patients are lacking. AIMS: To describe factors associated with the assessment by PCPs of COPD severity and those associated with impaired health status, as assessed by patient-reported outcomes. METHODS: This cross-sectional study evaluated health-related quality of life (HRQL) in 2,294 COPD patients from five European countries. The severity of COPD was clinically judged by the PCPs and GOLD stage severity was calculated using spirometry data. RESULTS: PCPs' categories of severity reflected a wider range of HRQL scores (St George's Respiratory Questionnaire (SGRQ) total score: mild 30.3; moderate 41.7; severe 55.0; very severe 66.1) than GOLD severity grading (Stage I 38.2; Stage II 41.1; Stage III 49.9; Stage IV 58.5). Multiple ordinal logistic regression models showed that factors most closely related to PCP-rated COPD severity were Medical Research Council (MRC) dyspnoea grade, forced expiratory volume in 1 second (FEV1) percent predicted, HRQL score (either SGRQ or COPD Assessment Test (CAT)), and previous hospitalisations (model generalised R²=0.45 or 0.44 (SQRQ or CAT in model, respectively); all factors p<0.0001). Factors with the highest association with HRQL scores (SGRQ or CAT) were MRC dyspnoea grade, COPD severity (PCP-rated), sputum production, and number of co-morbidities (model R²=0.46 or 0.37 (SQRQ or CAT in multiple linear regression model, respectively); all factors p<0.0001). CONCLUSIONS: PCPs successfully graded COPD severity clinically and appeared to have greater discriminative power for assessing severity in COPD than FEV1-based staging. Their more holistic approach appeared to reflect the patients' HRQL rating and was consistent across five European countries.

Prevalence of low-risk and high-risk types of human papillomavirus and other risk factors for HPV infection in Germany within different age groups in women up to 30 years of age: an epidemiological observational study.

Human papillomavirus (HPV) infection is frequent in young women and persistent infection may lead to cervical cancer. Therefore, vaccination against HPV is recommended for young women in the age group from 12-17 years in Germany. However, epidemiological data on the prevalence of HPV types and risk factors for infection for younger women in Germany is scarce. To address this, an observational study was performed in Germany including 1,692 women aged 10-30 years. After a routine Pap smear, cervical swabs were tested for high-risk and low-risk HPV, respectively, using the Hybrid Capture 2 (HC2) test, and genotyped using the PCR-based tests SPF(10)/LiPA(25) and PapilloCheck®. In addition, the women were interviewed regarding their medical history and lifestyle factors. Three hundred seventy-seven (22.28%) women had positive HC2 results. The proportion of HPV positive women was highest in the 20-22 age group with 28.3%. Predominant HPV types were HPV 16, 42, 51 and HPV 16, 51, 31 as defined by PapilloCheck® and SPF(10)/LiPA(25), respectively. 95.8% of women did not show signs of any cervical lesion. Adjusted analysis identified number of sexual partners (OR:1.105; 95% CI:[1.069-1.142]), smoking (OR:1.508; [1.155-1.968]), and vaccination against HPV (OR:0.589; [0.398-0.872]) rather than increasing age as risk associated with HPV infection. Comparison of the genotyping assays showed that they correspond well regarding the high-risk HPV types but less well for low-risk HPV types. This epidemiological study shows that high-risk HPV infection is common in young women in Germany. According to our data, vaccination of young women could have a potential impact on the prevention of HPV infection and cervical disease.

Fosamprenavir/ritonavir plus tenofovir does not affect amprenavir pharmacokinetics: no effect of tenofovir.

The effect of tenofovir disoproxil fumarate (TDF) in combination with two boosted fosamprenavir regimens on amprenavir pharmacokinetic parameters was assessed in this prospective phase I crossover study with 30 healthy volunteers. The co-administration of TDF 300 mg once a day with fosamprenavir/ritonavir 1400/200 mg or 1400/100 mg once a day has no effect on the pharmacokinetics of amprenavir and results in non-significant increases of ritonavir pharmacokinetic parameters, suggesting that no dose modification is necessary when combining fosamprenavir/ritonavir with TDF.

Use of Fondaparinux Off-Label or Approved Anticoagulants for Management of Heparin-Induced Thrombocytopenia.

BACKGROUND: Life-threatening heparin-induced thrombocytopenia (HIT) is treated with the alternative nonheparin anticoagulants argatroban, lepirudin, or danaparoid. Frequently, the pentasaccharide fondaparinux is used off-label. OBJECTIVES: The authors sought to investigate the safety and efficacy of the different anticoagulants for treating HIT. METHODS: In a national, multicenter registry study, hospitalized patients who were diagnosed with HIT, an at least intermediate clinical HIT-risk (4Ts score ≥4 points), and received treatment with ≥1 dose of the aforementioned anticoagulants were included. Main outcome measures were the incidences of HIT-specific complications (thromboembolic venous/arterial events, amputations, recurrent/persistent thrombocytopenia, skin lesions) and bleedings. RESULTS: Of 195 patients, 46 (23.6%), 4 (2.1%), 61 (31.3%), and 84 (43.1%) had been treated first-line with argatroban, lepirudin, danaparoid, and fondaparinux, respectively. The composite endpoint of HIT-specific complications (thromboembolic events, amputation, skin necrosis) occurred in 11.7% of patients treated with approved alternative anticoagulation and in 0.0% of fondaparinux-treated patients. The all-cause in-hospital mortality rates were 14.4% during approved alternative anticoagulation and 0.0% during fondaparinux treatment. Bleeding complications occurred in alternatively anticoagulated patients and in fondaparinux-treated patients in 6.3% and 4.8%, respectively. Post hoc analysis of clinical and laboratory features confirmed "true" HIT in at least 74 of 195 (38.0%) patients; 35 of 74 (47.3%) were treated with fondaparinux. CONCLUSIONS: Fondaparinux is effective and safe in suspected acute HIT; no HIT-specific complications occurred in the fondaparinux-treated patients, even among those with a high clinical HIT probability. Further data from randomized controlled trials are urgently needed because lepirudin was recalled from the market; danaparoid access has been limited and is not approved in the United States; and argatroban is contraindicated in patients with impaired liver function, and activated partial thromboplastin time confounding may interfere with monitoring.

SAfety of Fondaparinux in transoesophageal echocardiography-guided Electric cardioversion of Atrial Fibrillation (SAFE-AF) study: a pilot study.

BACKGROUND: Current guidelines recommend unfractionated heparin (UFH) or low-molecular-weight heparin plus an oral anticoagulant for the prevention of thromboembolism in patients undergoing electric cardioversion of atrial fibrillation (AF). Selective factor Xa inhibitors, such as fondaparinux, which has a favourable benefit-risk profile in the prevention and treatment of venous thromboembolism and the management of acute coronary syndromes, have not been systematically evaluated in this setting. AIM: To evaluate the efficacy and safety of fondaparinux versus standard treatment in patients undergoing echocardiographically-guided cardioversion of AF. METHODS: In this multicentre, randomized, open-label, controlled, two-parallel-group, phase II pilot study, patients with AF undergoing electric cardioversion following transoesophageal echocardiography (TEE) were randomized to fondaparinux or standard therapy (UFH plus vitamin K antagonist [VKA]). Patients showing an atrial thrombus in the first TEE (clot-positive) were randomized to treatment with fondaparinux or standard care for 4 weeks before cardioversion. RESULTS: The primary endpoint (combined rate of cerebral neurological events, systemic thromboembolism, all-cause death and major bleeding events) occurred in 3 of 174 (1.7%) patients on fondaparinux and 2 of 170 (1.2%) patients on UFH+VKA. The rate of thrombus disappearance among clot-positive patients was higher in the fondaparinux arm (11 of 14; 78.6%) than in the UFH+VKA arm (7 of 14; 50.0%). Incidences of adverse events were similar (45.4% with fondaparinux and 46.5% with UFH+VKA). CONCLUSION: In this pilot study in patients with TEE-guided cardioversion, the use of fondaparinux appeared to be well tolerated, with similar efficacy to UFH+VKA. Furthermore, a trend to greater thrombus resolution was observed.

Frequent off-label use of fondaparinux in patients with suspected acute heparin-induced thrombocytopenia (HIT)--findings from the GerHIT multi-centre registry study.

INTRODUCTION: In life-threatening immune heparin-induced thrombocytopenia (HIT), treatment with an approved non-heparin anticoagulant is essential. However, off-label use with fondaparinux has been reported in the literature. The study aim was to collect data on "real-life" management of patients with suspected acute HIT regarding diagnostic and therapeutic strategies. PATIENTS AND METHODS: In a national multi-centre registry study, patients with a 4T's HIT-probability score of ≥ 4 points and treatment with at least one dose of (A)rgatroban, (L)epirudin, (D)anaparoid, or (F)ondaparinux were retrospectively evaluated. RESULTS: Of 195 patients, the 4T's scores were 4/5/6/7/8 points in 46 (23.6%)/50 (25.6%)/74 (38.0%)/13 (6.7%)/7 (3.6%) patients, respectively. During heparin therapy, 47 (24.1%) thromboembolic events, 5 (2.6%) skin lesions, 1 (0.5%) amputation, 24 (12.3%) Hb-relevant bleedings, and 2 (1.0%) fatalities occurred. A functional heparin-induced platelet activation assay was performed in 96.9%, a platelet factor 4/heparin-dependent enzyme immunoassay in 89.2%, a particle gel immunoassay in 12.3%, and a serotonin-release assay in none of the patients. Argatroban was used in 16.4%, lepirudin in 2.1%, danaparoid in 23.6%, fondaparinux in 40.0% of the patients; the sequential therapy strata were: AF (5.6%), DA (5.6%), DF (2.6%), DL (2.1%), ADF (1.5%), and DFL (0.5%). CONCLUSIONS: The current diagnostic laboratory strategy for suspected HIT is mostly (>96%) based on the recommended 2-step strategy (immunoassay plus functional assay). However, there is a wide fondaparinux off-label use (up to 50.3%) for suspected HIT, even in those patients with a high clinical pretest probability. Efficacy and safety of fondaparinux for HIT-treatment require further evaluation.

Influence of salmeterol/fluticasone via single versus separate inhalers on exacerbations in severe/very severe COPD.

BACKGROUND: Patients with severe or very severe chronic obstructive pulmonary disease (COPD) frequently suffer repeated exacerbations generating high health care utilization costs. Combined corticosteroid and bronchodilator treatment using a single inhaler might - via improved compliance - reduce exacerbation rates. OBJECTIVES: Our aim was to obtain descriptive data on exacerbation rates in patients with severe or very severe COPD (GOLD Stages III and IV as per GOLD 2009 classification) receiving salmeterol xinafoate/fluticasone propionate via a single inhaler (SFC) or via separate inhalers (Sal/FP) in addition to individual existing therapy in order to investigate the potential benefit of a fixed combination device as compared with two separate devices due to potentially improved patients' compliance. METHODS: This prospective, randomized, open-label, parallel-group, multi-center, exploratory study was conducted in Germany in 2007-2009. Patients were required to have suffered ≥ 2 moderate/severe exacerbations in the preceding year. RESULTS: 213 patients (SFC: 108 patients, Sal/FP: 105 patients) from 23 centers were evaluated. Approximately 25% of patients showed COPD Stage IV. On average patients had suffered 2.3 ± 0.6 moderate/severe exacerbations in the preceding year. The annual rate of moderate/severe exacerbations observed in the study was similar in both treatment groups (SFC: 0.86 ± 0.13; Sal/FP: 0.86 ± 0.14; exacerbation rate ratio SFC/Sal/FP: 1.00; p = 0.73; negative binomial model). Compliance was high and comparable in both groups. Besides COPD exacerbations, pneumonia (5.6%) and nasopharyngitis (5.2%) were the most common adverse events. CONCLUSION: Observed exacerbation rates were lower than those reported at baseline. No substantial difference was observed between administration of salmeterol xinafoate/fluticasone propionate via a single inhaler and separate inhalers. Treatment was safe and well tolerated.

Topotecan/cisplatin compared with cisplatin/etoposide as first-line treatment for patients with extensive disease small-cell lung cancer: final results of a randomized phase III trial.

INTRODUCTION: This phase III study compared efficacy and safety of topotecan-cisplatin (TP) versus topotecan-etoposide (TE) versus cisplatin-etoposide (PE) in chemo-naïve extensive disease small-cell lung cancer patients. METHODS: Seven hundred and ninety-five previously untreated patients were randomly assigned to TP (topotecan 1mg/m IV, d1-5; cisplatin 75 mg/m IV, d5; n = 358), PE (cisplatin 75 mg/m IV, d1; etoposide 100 mg/m IV, d1-3; n = 345) or TE (topotecan 1mg/m IV, d1-5; etoposide 80 mg/m IV, d3-5; n = 92). Primary endpoint was superiority of TP compared with PE, with the possibility to switch to a noninferiority test. RESULTS: The TE arm was closed after recommendations by the Independent Data Safety Monitoring Board. Median survival was similar and met the predefined endpoint of noninferiority of TP to PE (44.9 versus 40.9 weeks; p = 0.40). One-year survival rate showed 39.7% for TP versus 36.1% for PE (p = 0.29). Median time to progression was significantly longer with TP (27.4 versus 24.3 weeks, p = 0.01). Overall response rates were significantly higher for TP (55.5% versus 45.5%, p = 0.01).Hematologic toxicity was slightly higher for TP regarding G 3/4 neutropenia (35.7/35.8%), G 3/4 thrombocytopenia (18.7/4.8%), G 3/4 anemia (11.6/6.7%), febrile neutropenia (2.0/2.7%), sepsis (1.7/1.2%), and toxicity-related deaths (5.2/2.7%). CONCLUSION: TP is noninferior to PE in overall survival and superior in time to progression and overall response rates. Because of slightly worse toxicity profile TP is not a first-line standard treatment for patients with extensive disease small-cell lung cancer.

Ropinirole improves depressive symptoms and restless legs syndrome severity in RLS patients: a multicentre, randomized, placebo-controlled study.

Comorbid depressive symptoms in restless legs syndrome (RLS) remain a treatment challenge, as some antidepressants aggravate RLS symptoms. Preliminary data in depressive patients suggest antidepressant properties of ropinirole. The present study investigates the effects of ropinirole immediate release (IR) on depressive symptoms and RLS severity. A multicenter, placebo-controlled, double-blind randomized (3:1) study was performed including patients with moderate to severe idiopathic RLS and at least mild depressive symptoms. Ropinirole IR (in flexible doses up to 4 mg/day) or placebo was given for 12 weeks including an uptitration phase of 7 weeks. Visits were scheduled at screening, baseline, and weeks 1, 4, and 12 with additional telephone contacts for dosing decisions. The modified intent to treat population comprised 231 patients (171 ropinirole, 60 placebo). The MADRS (Montgomery-Asberg Depression Rating Scale) scores decreased from baseline to week 12 from 18.8 to 8.7 in the ropinirole group and from 18.4 to 12.1 in the placebo group (primary endpoint, adjusted mean treatment difference -3.6 (95% CI: -5.6 to -1.6, significance in favor of ropinirole: P < 0.001). The superiority of ropinirole compared to placebo was confirmed by the Hamilton Scale for Depression and Beck Depression Inventory-II scores. RLS severity scores (IRLS) decreased by 14.7 (ropinirole) and by 9.9 (placebo, P < 0.001) points. Three out of four subdomains of the Medical Outcomes Study Sleep Scale improved significantly. The findings indicate that mild to moderate depressive symptoms should not be treated before sufficient therapy for RLS. Antidepressant medication can be necessary if depression symptoms still persist even if RLS symptoms are ameliorated.

Randomized comparison of eptifibatide versus abciximab in primary percutaneous coronary intervention in patients with acute ST-segment elevation myocardial infarction: results of the EVA-AMI Trial.

OBJECTIVES: The aim of this study was to compare eptifibatide and abciximab as adjuncts to primary percutaneous coronary intervention (PCI). BACKGROUND: The glycoprotein (GP) IIb/IIIa receptor inhibitor abciximab as adjunct to primary PCI in patients with ST-segment elevation myocardial infarctions has been shown to reduce ischemic complications and improve clinical outcomes. So far, no trial has been performed to compare the efficacy of another GP IIb/IIIa receptor inhibitor, eptifibatide, and abciximab in primary PCI. METHODS: A total of 427 patients with ST-segment elevation myocardial infarctions <12 h and planned primary PCI were randomized to double-bolus eptifibatide (n = 226) followed by a 24-h infusion or single-bolus abciximab (n = 201) followed by a 12-h infusion. In this noninferiority trial, the primary end point was the incidence of complete (> or =70%) ST-segment resolution (STR) 60 min after PCI, a measure of myocardial reperfusion. The assumption was a 60% complete STR rate in the abciximab group. The noninferiority margin was set to 15%. RESULTS: The incidence of complete STR at 60 min after PCI in the intention-to-treat analysis was 62.6% after eptifibatide and 56.3% after abciximab (adjusted difference: 7.1%; 95% confidence interval: 2.7% to 17.0%). All-cause mortality 6.2% versus 4.5% (p = 0.50); reinfarction 0.4% versus 3.5% (p = 0.03); target vessel revascularization 4.4% versus 6.5% (p = 0.40); the combined end point of death, nonfatal reinfarction, and target vessel revascularization 10.6% versus 10.9% (p = 0.90); stroke 0.5% versus 0.5% (p = 1.00) after 6 months; and Thrombolysis In Myocardial Infarction major bleeding complications 4.0% versus 2.0% (p = 0.20) after 30 days were observed after eptifibatide and abciximab, respectively. CONCLUSIONS: Eptifibatide as an adjunct to primary PCI is equally as effective as abciximab with respect to STR.

National survey of guideline-compliant COPD management among pneumologists and primary care physicians.

The aim of this survey was to investigate guideline-compliant COPD management among pneumologists and primary care physicians (PCPs). A multiple-choice questionnaire was sent out to 1836 PCPs and 863 pneumologists in Germany. The questions focused on the key aspects of current national and international COPD guidelines. Four hundred eighty-six PCPs and 359 pneumologists participated in the study. It was found that pneumologists held the GOLD guideline in high regard (60.4%), while PCPs tended to follow the German National COPD guideline (66.5%). Differences were also found with regard to diagnosis and classification of COPD on the basis of spirometric and clinical criteria. The current GOLD classification of moderate and severe COPD was used by 36.2% and 23.4% of the pneumologists, respectively, and by 32.1% and 20.2% of the PCPs. Although PCPs and pneumologists endorsed educational measures to help patients quit smoking, implementation was still inadequate. The two most important therapeutic goals were to improve quality of life and prevent exacerbations. Except for the criteria for the use of steroids and the implementation of pulmonary rehabilitation measures, treatment of COPD based on severity class was largely in compliance with guidelines. However, appreciably more PCPs than pneumologists incorrectly assessed the evidence-based clinical benefits of various therapeutic measures. The study shows that, despite the popularity of COPD guidelines, deficits exist among pneumologists and PCPs with respect to diagnosis and treatment of COPD and practical implementation of educational measures. These deficiencies in guideline conformity might be best addressed through targeted continuing-education measures.
