Cost-effectiveness of extended-release niacin/laropiprant added to a stable simvastatin dose in secondary prevention patients not at cholesterol goal in Germany

Coronary heart disease (CHD) remains the leading cause of death in Germany despite statin use to reduce low-density lipoprotein cholesterol (LDL-C) levels; improving lipids beyond LDL-C may further reduce cardiovascular risk. A fixed-dose combination of extended-release niacin (ERN) with laropiprant (LRPT) provides comprehensive lipid management. We adapted a decision-analytic model to evaluate the economic value (incremental cost-effectiveness ratio [ICER] in terms of costs per life-years gained [LYG]) of ERN/LRPT 2 g over a lifetime in secondary prevention patients in a German setting. Two scenarios were modelled: (1) ERN/LRPT 2 g added to simvastatin 40 mg in patients not at LDL-C goal with simvastatin 40 mg; (2) adding ERN/LRPT 2 g compared with titration to simvastatin 40 mg in patients not at LDL-C goal with simvastatin 20 mg. In both scenarios, adding ERN/LRPT was cost-effective relative to simvastatin monotherapy at a commonly accepted threshold of €30,000 per LYG; ICERs for ERN/LRPT were €13,331 per LYG in scenario 1 and €17,684 per LYG in scenario 2. Subgroup analyses showed that ERN/LRPT was cost-effective in patients with or without diabetes, patients aged ≤65 or >65 years and patients with low baseline high-density lipoprotein cholesterol levels; ICERs ranged from €10,342 to €15,579 in scenario 1, and from €14,081 to €20,462 in scenario 2. In conclusion, comprehensive lipid management with ERN/LRPT 2 g is cost-effective in secondary prevention patients in Germany who have not achieved LDL-C goal with simvastatin monotherapy

Intensive care unit-related fluconazole use in Spain and Germany: patient characteristics and outcomes of a prospective multicenter longitudinal observational study

Background: Candida spp. are a frequent cause of nosocomial bloodstream infections worldwide. Objective: To evaluate the use patterns and outcomes associated with intravenous (IV) fluconazole therapy in intensive care units in Spain and Germany. Patients and methods: The research reported here was a prospective multicenter longitudinal observational study in adult intensive care unit patients receiving IV fluconazole. Demographic, microbiologic, therapy success, length of hospital stay, adverse event, and all-cause mortality data were collected at 14 sites in Spain and five in Germany, from February 2004 to November 2005. Results: Patients (n = 303) received prophylaxis (n = 29), empiric therapy (n = 140), preemptive therapy (n = 85), or definitive therapy (n = 49). A total of 298 patients (98.4%) were treated with IV fluconazole as first-line therapy. The treating physicians judged therapy successful in 66% of prophylactic, 55% of empiric, 45% of preemptive, and 43% of definitive group patients. In the subgroup of 152 patients with proven and specified Candida infection only, 32% suffered from Candida specified as potentially resistant to IV fluconazole. The overall mortality rate was 42%. Conclusion: Our study informs treatment decision makers that approximately 32% of the patients with microbiological results available suffered from Candida specified as potentially resistant to IV fluconazole, highlighting the importance of appropriate therapy

Caspofungin for treatment of invasive aspergillosis in Germany: results of a pre-planned subanalysis of an international registry

<p>Abstract</p> <p>Background</p> <p>This study is a pre-planned country-specific subanalysis of results in Germany from a multinational multicenter registry to prospectively assess real-world experience with caspofungin administered for treatment of proven or probable invasive aspergillosis (IA).</p> <p>Methods</p> <p>Data from patients treated with caspofungin for a single episode of IA were collected. Effectiveness was determined by the local investigator as favorable (complete or partial response) or unfavorable (stable disease, failure or death) at the end of caspofungin therapy. Descriptive statistics with binomial exact confidence intervals were employed.</p> <p>Results</p> <p>Forty-two consecutive patients were identified in three German centers. Three patients (7%) had proven IA and 39/42 (93%) had probable IA (modified European Organization for Research and Treatment of Cancer/Mycosis Study Group (EORTC/MSG) criteria). Forty-one patients had pulmonary IA and one had tracheal IA. Caspofungin monotherapy was received by 36/42 patients (86%); of these, 26/36 (72%) received salvage therapy. A favorable response was observed in 29/42 patients (69%; 95% CI 53 to 82%); of these, 21/29 (72%) had a complete and 8/29 (28%) a partial response. Favorable response rate was 69% in patients with monotherapy (95% CI 52% to 84%; 25/36 patients), and 67% in patients receiving combination therapy (95% CI 22% to 96%; 4/6 patients). Favorable response rate in patients with first line therapy was 64% (95% CI 31% to 89%; 7/11 patients), and 73% in patients with second line therapy (95% CI 54% to 88%; 20/30 patients). No adverse events were reported. In total, 35/42 patients (83%; 95% CI 69 to 93%) survived seven days after completion of caspofungin therapy.</p> <p>Conclusions</p> <p>These real-life findings in Germany are consistent with the international findings from this registry and with findings from randomized studies.</p

Fear of hypoglycaemia: defining a minimum clinically important difference in patients with type 2 diabetes

<p>Abstract</p> <p>Background</p> <p>To explore the concept of the Minimum Clinically Important Difference (MID) of the Worry Scale of the Hypoglycaemia Fear Survey (HFS-II) and to quantify the clinical importance of different types of patient-reported hypoglycaemia.</p> <p>Methods</p> <p>An observational study was conducted in Germany with 392 patients with type 2 diabetes mellitus treated with combinations of oral anti-hyperglycaemic agents. Patients completed the HFS-II, the Treatment Satisfaction Questionnaire for Medication (TSQM), and reported on severity of hypoglycaemia. Distribution- and anchor-based methods were used to determine MID. In turn, MID was used to determine if hypoglycaemia with or without need for assistance was clinically meaningful compared to having had no hypoglycaemia.</p> <p>Results</p> <p>112 patients (28.6%) reported hypoglycaemic episodes, with 15 patients (3.8%) reporting episodes that required assistance from others. Distribution- and anchor-based methods resulted in MID between 2.0 and 5.8 and 3.6 and 3.9 for the HFS-II, respectively. Patients who reported hypoglycaemia with (21.6) and without (12.1) need for assistance scored higher on the HFS-II (range 0 to 72) than patients who did not report hypoglycaemia (6.0).</p> <p>Conclusion</p> <p>We provide MID for HFS-II. Our findings indicate that the differences between having reported no hypoglycaemia, hypoglycaemia without need for assistance, and hypoglycaemia with need for assistance appear to be clinically important in patients with type 2 diabetes mellitus treated with oral anti-hyperglycaemic agents.</p

Simvastatin After Orthotopic Heart Transplantation: Costs and Consequences

Objective: Recent data indicate that the combination of a low cholesterol diet and simvastatin following heart transplantation is associated with significant reduction of serum cholesterol levels, lower incidence of graft vessel disease (GVD) and significantly superior 4-year survival rates than dietary treatment alone. On the basis of this first randomised long term study evaluating survival as the clinical end-point, we investigated the cost effectiveness of the above regimens as well as the long term consequences for the patient and for heart transplantation as a high-tech procedure. Design and setting: The perspective of the economic analysis was that of the German health insurance fund. Life-years gained were calculated on the basis of the Kaplan-Meier survival curves from the 4-year clinical trial and from the International Society for Heart and Lung Transplantation (ISHLT) overall survival statistics. Incremental costs and incremental cost-effectiveness ratios were determined using various sources of data, and both costs and consequences were discounted by 3% per year. Sensitivity analyses using alternative assumptions were conducted in addition to the base-case analysis. Patients and participants: As in the original clinical trial, the target population of the economic evaluation comprised all heart transplant recipients on standard triple immunosuppression consisting of cyclosporin, azathioprine and prednisolone, regardless of the postoperative serum lipid profile. Interventions: The therapeutic regimens investigated in the analysis were the American Heart Association (AHA) step II diet plus simvastatin (titrated to a maximum dosage of 20 mg/day) and AHA step II diet alone. Main outcome measures and results: Four years of treatment with simvastatin (mean dosage 8.11 mg/day) translated into an undiscounted survival benefit per patient of 2.27 life-years; 0.64 life-years within the trial period and 1.63 life-years thereafter. Discounted costs per year of life gained were $US1050 (sensitivity analyses$US800 to $US15 400) for simvastatin plus diet versus diet alone and$US18 010 (sensitivity analyses $US17 130 to$US21 090) for heart transplantation plus simvastatin versus no transplantation (all costs reflect 1997 values; $US1 = 1.747 Deutschmarks). Conclusions: Prevention of GVD with simvastatin after heart transplantation was cost effective in all the scenarios examined with impressive prolongation of life expectancy for the heart recipient. Simvastatin also achieved an internationally robust 21% improvement in the cost effectiveness of heart transplantation compared with historical cost-effectiveness data.Pharmacoeconomics, Simvastatin, Cost-effectiveness, Coronary-disorders, Hypercholesterolaemia, Randomised-controlled-trials, Heart-transplant, HMG-CoA-reductase-inhibitors, Graft-versus-host-disorders, Mortality

Prospective Study of Amphotericin B Formulations in Immunocompromised Patients in 4 European Countries

Background. Amphotericin B is a widely used broad-spectrum antifungal agent, despite being associated with significant adverse events, including nephrotoxicity. Methods. The present prospective study collected data on outcomes for 418 adult patients treated consecutively with polyenes in hematology and oncology wards in 20 hospitals in Europe. Results. Patients initially received amphotericin B deoxycholate (62% of patients), liposomal amphotericin B (27%), or other lipid formulations of amphotericin B (11%). Of the patients initially treated with amphotericin B deoxycholate, 36% had therapy switched to lipid formulations of amphotericin B, primarily because of increased serum creatinine levels (in 45.7% of patients) or other amphotericin B–attributable adverse events (in 41.3% of patients). Nephrotoxicity, which was defined as a 50% increase in the serum creatinine level, developed in 57% of patients with normal kidney function at baseline. Predictors of nephrotoxicity included formulation type and duration of treatment. Compared with patients without nephrotoxicity, patients with nephrotoxicity had a higher mortality rate (24%), and their mean length of stay in the hospital was prolonged by 8.6 days. Slight increases in the serum creatinine level (i.e., 50%) were associated with a significantly longer stay in the hospital. Severe nephrotoxicity (i.e., a 200% increase in the serum creatinine level) was a significant predictor of death, as were severe underlying medical conditions and documented fungal infection. Conclusion. This prospective study confirmed that, in European hospitals, amphotericin B formulations have a major influence on the length of stay in the hospital and nephrotoxicity-associated mortality
