Introduction Phosphodiesterase type-5 (PDE-5) inhibitors have previously been evaluated for their efficacy and safety in various clinical trials in men with erectile dysfunction (ED) with or without associated comorbidities. Aim This is the first prospective, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of a PDE-5 inhibitor (i.e., vardenafil) in an exclusive population of men with ED and dyslipidemia. Main Outcome Measures Three coprimary efficacy measurements (Sexual Encounter Performance [SEP]2, SEP3, International Index of Erectile Function-Erectile Function [IIEF-EF] domain scores) were used to assess the differential effect of vardenafil vs. placebo in this patient population. Adverse events (AEs) safety data were obtained to compare safety outcomes. Methods This 12-week of randomized, double-blind, placebo-controlled study was conducted in 59 U.S. centers. Patients received either on-demand, flexible-dose vardenafil 10 mg (titrated to 5 mg or 20 mg based upon efficacy and safety) or placebo. Results Of the 712 patients screened and entered into the study, 395 were randomized. Baseline demographics for the intent-to-treat population included: mean age, 54.4 years (±7.5 standard deviation [SD]); 76% Caucasian; mean body mass index (BMI), 31.7 kg/m2 (±12.7 SD); 47% past/present smoker; and 42% severe ED. Aside from dyslipidemia, other comorbidities included hypertension, 61%; obesity (i.e., BMI ≥ 30), 51%; and type 1 or 2 diabetes, 40%. During the 12-week treatment period, the least squares (LS) adjusted mean success rates in patients on vardenafil vs. placebo were: SEP2, 79.09% vs. 51.92%; and SEP3, 66.69% vs. 33.83% (P <0.001). The LS adjusted mean IIEF-EF domain score for week 12 using LOCF was 21.99 in patients on vardenafil therapy vs. 14.83 in those on placebo (P <0.001). The most commonly encountered AEs were headache and nasal congestion. Conclusions Vardenafil was demonstrated to be safe and effective for managing ED in men with ED and associated dyslipidemia. The results of this study support the role of expanded research on outcomes related to effective ED treatment and aggressive lipid control.

Background. Highly pathogenic avian influenza H5N1 viruses remain a threat to human health, with potential to become pandemic agents.Methods. This phase III, placebo-controlled, observer-blinded study evaluated the immunogenicity, cross-reactivity, safety, and lot consistency of 2 doses of oil-in-water (AS03A) adjuvanted H5N1 A/Indonesia/05/2005 (3.75 μg hemagglutinin antigen) prepandemic candidate vaccine in 4561 adults aged 18–91 years.Results. Humoral antibody responses in the H5N1 vaccine groups fulfilled US and European immunogenicity licensure criteria for pandemic vaccines in all age strata 21 days after the second dose. At 6 months after the administration of the primary dose, serum antibody seroconversion rates continued to fulfill licensure criteria. Neutralizing cross-clade immune responses were demonstrated against clade 1 A/Vietnam/1194/2004. Consistency was demonstrated for 3 consecutive H5N1 vaccine lots. Temporary injection-site pain was more frequent with H5N1 vaccine than placebo (89.3% and 70.7% in the 18–64 and ≥65 years strata vs 22.2% and 14.4% in the placebo groups). Unsolicited adverse event frequency, including medically attended and serious events, was similar between groups through day 364.Conclusions. In adults and elderly adults, AS03A-adjuvanted H5N1 candidate vaccine was highly immunogenic for A/Indonesia/05/2005, with cross-reactivity against A/Vietnam/1194/2004. Temporary injection site reactions were more frequent with H5N1 vaccine than placebo, although the H5N1 vaccine was well tolerated overall.Clinical Trials Registration. NCT00616928.

The vaccine Zostavax has been shown to prevent herpes zoster (HZ) and postherpetic neuralgia and is recommended for individuals >60 years of age. This study compared the safety and the immunogenicity of a refrigerator-stable formulation (Zostavax refrigerated) with those of the current formulation (Zostavax frozen) in subjects >50 years of age. Subjects with a negative history for HZ were randomized 1:1 to receive one dose of either formulation. Enrollment was stratified 1:2 by age (50 to 59 years and >60 years). Safety was evaluated for 28 days postvaccination. Varicella-zoster virus (VZV) antibody responses were measured by a glycoprotein enzyme-linked immunosorbent assay (gpELISA). The primary endpoints were the VZV antibody geometric mean titer (GMT; day 28), the VZV antibody geometric mean rise (GMR; days 1 to 28), and the incidence of vaccine-related serious adverse experiences (AEs) over 28 days. The refrigerated (n ‫؍‬ 182) and frozen (n ‫؍‬ 185) formulations induced similar GMTs (727.4 and 834.4 gpELISA units/ml, respectively); the estimated GMT ratio (refrigerated formulation/frozen formulation) was 0.87 (95% confidence interval, 0.71 to 1.07). The GMRs were 2.6-and 2.9-fold, respectively. No vaccine-related serious AEs were reported in either group, and the safety profiles of the formulations were generally similar. The frequencies of injection-site AEs during follow-up were 35.6% and 46.4% in the refrigerated and the frozen formulation groups, respectively, and were generally mild. The frequencies of systemic AEs were similar in the two groups, and those of vaccine-related AEs were ϳ6% in both groups. The refrigerator-stable formulation of Zostavax has an acceptable safety profile and is as immunogenic as the frozen formulation; thus, the vaccine may be used in clinical settings where freezer availability is limited.Herpes zoster (HZ), also known as shingles, is an often serious condition associated with the reactivation of varicellazoster virus (VZV) in individuals who have been exposed to the virus earlier in life (11,12). After the initial infection, which manifests clinically as chickenpox, VZV can become latent and reside in the dorsal or cranial nerve ganglia. The reactivation of VZV as HZ is usually characterized by a unilateral, dermatomally distributed cutaneous rash.The incidence of HZ in the general population has been estimated to be between 0.3 and 0.4% annually in the United States, Canada, and Europe (6, 9, 22, 37). The risk of developing HZ increases dramatically upon reaching 50 years of age, and this risk subsequently increases to a rate that approximates 1% per year by the age of 75 years (30,31,38). The long-lasting pain associated with HZ, termed postherpetic neuralgia (PHN), is the most common complication and cause of morbidity from HZ in immunocompetent patients (12,17,29,36). Worldwide, the lifetime risk of developing HZ has recently been estimated to be close to 30% in the general population and can be as high as 50% in individuals who reach the age of 85 years (9,13,18).

During the 14-day treatment period in a population with frequent heartburn who were likely to select a medication without consulting a prescriber, lansoprazole 15 mg once daily showed rapid and sustained effectiveness throughout a 24-hour period and was well tolerated.

To determine the efficacy and safety of a single-dose (1200 mg) soft gel insert (vaginal ovule) with miconazole nitrate (2%) topical cream compared with Monistat 7 (miconazole nitrate 2%) Vaginal Cream (Advanced Care Products, North Brunswick NJ) in treating vulvovaginal candidiasis (VVC), two randomized, single-blind, multicenter, controlled, comparative phase III studies were performed. Five hundred fifty-eight patients received either a single-dose miconazole nitrate (1200 mg) ovule or seven consecutive doses of Monistat 7. Ovule arm patients also received miconazole nitrate 2% cream for symptom relief, as needed, up to twice daily. The primary end point was a therapeutic cure. Also evaluated were time to complete symptom relief, safety, and patient preference. The ovule had overall cure rates of 71.7% (71 of 99 patients) and 61.5% (64 of 104 patients). Monistat 7 had overall cure rates of 70.1% (68 of 97 patients) and 61.1% (55 of 90 patients). A significantly greater proportion of patients experienced complete symptom relief by day 3 with the ovule (p = 0.008 and p = 0.025), and time to complete relief was significantly faster (median 4 versus 5 days and 3 versus 4 days). Overall safety results were consistent between groups in both studies. Miconazole nitrate vaginal ovule is as safe and efficacious in curing VVC as Monistat 7 while providing complete symptom relief significantly faster. Patients preferred the ovule to prior therapy.
