Efficacy Rates (efficacy + rate)
Selected AbstractsPhotodynamic Therapy for the Treatment of Cutaneous Neoplasia, Inflammatory Disorders, and PhotoagingDERMATOLOGIC SURGERY, Issue 5 2009EMILY TIERNEY MD BACKGROUND Photodynamic therapy (PDT) has demonstrated high efficacy, minimal side effects, and improved cosmetic outcome when used for the treatment of actinic keratoses (AK), basal cell carcinoma (BCC), squamous cell carcinoma, and photoaging. METHODS To review the literature on the use of PDT in dermatologic surgery using MEDLINE. RESULTS Published clinical studies using PDT in the treatment of AKs yield overall efficacy rates ranging from 50% to 71% with one treatment to as high as 88% to 90% with two or more treatments. For superficial BCC, initial clearance rates were 76% to 97%, and for Bowen's disease, initial clearance rates ranged from 72% to 94% overall. The use of PDT for photorejuvenation is a relatively new application of this technology, which has shown promise in improving the appearance of fine lines, pigmentary variation, and telangiectasias. CONCLUSIONS The advantages of photodynamic therapy include the capacity for noninvasive targeted therapy through topical application of aminolevulinic acid and methyl aminolevulinic acid, with outstanding cosmetic results. Although the theory behind the use of chemical photosensitizers and ultraviolet light to treat a wide variety of skin disorders is straightforward, the practical application of this technology is evolving. Additional research into the precise mechanisms of action for specific photosensitizers and optimal light sources will be highly beneficial to the advancement of this technology. [source] Insulin therapy in type 2 diabetes patients failing oral agents: cost-effectiveness of biphasic insulin aspart 70/30 vs. insulin glargine in the US,DIABETES OBESITY & METABOLISM, Issue 1 2007J. A. Ray Objectives:, To project the long-term clinical and economic outcomes of treatment with biphasic insulin aspart 30 (BIAsp 70/30, 30% soluble and 70% protaminated insulin aspart) vs. insulin glargine in insulin-naïve type 2 diabetes patients failing to achieve glycemic control with oral antidiabetic agents alone (OADs). Methods:, Baseline patient characteristics and treatment effect data from the recent ,INITIATE' clinical trial served as input to a peer-reviewed, validated Markov/Monte-Carlo simulation model. INITIATE demonstrated improvements in HbA1c favouring BIAsp 70/30 vs. glargine (,0.43%; p < 0.005) and greater efficacy in reaching glycaemic targets among patients poorly controlled on OAD therapy. Effects on life expectancy (LE), quality-adjusted life expectancy (QALE), cumulative incidence of diabetes-related complications and direct medical costs (2004 USD) were projected over 35 years. Clinical outcomes and costs were discounted at a rate of 3.0% per annum. Sensitivity analyses were performed. Results:, Improvements in glycaemic control were projected to lead to gains in LE (0.19 ± 0.24 years) and QALE (0.19 ± 0.17 years) favouring BIAsp 70/30 vs. glargine. Treatment with BIAsp 70/30 was also associated with reductions in the cumulative incidences of diabetes-related complications, notably in renal and retinal conditions. The incremental cost-effectiveness ratio was $46 533 per quality-adjusted life year gained with BIAsp 70/30 vs. glargine (for patients with baseline HbA1c , 8.5%, it was $34 916). Total lifetime costs were compared to efficacy rates in both arms as a ratio, which revealed that the lifetime cost per patient treated successfully to target HbA1c levels of <7.0% and , 6.5% were $80 523 and $93 242 lower with BIAsp 70/30 than with glargine, respectively. Conclusions:, Long-term treatment with BIAsp 70/30 was projected to be cost-effective for patients with type 2 diabetes insufficiently controlled on OADs alone compared to glargine. Treatment with BIAsp 70/30 was estimated to represent an appropriate investment of healthcare dollars in the management of type 2 diabetes. [source] Guidelines for the Management of Tinea Capitis in ChildrenPEDIATRIC DERMATOLOGY, Issue 3 2010Talia Kakourou M.D. Tinea capitis always requires systemic treatment because topical antifungal agents do not penetrate the hair follicle. Topical treatment is only used as adjuvant therapy to systemic antifungals. The newer oral antifungal agents including terbinafine, itraconazole, and fluconazole appear to have efficacy rates and potential adverse effects similar to those of griseofulvin in children with TC caused by Trichophyton species, while requiring a much shorter duration of treatment. They may be, however, more expensive (Grading of recommendation A; strength of evidence 1a). Griseofulvin is still the treatment of choice for cases caused by Microsporum species. Its efficacy is superior to that of terbinafine (Grading of recommendation A; strength of evidence 1b), and although its efficacy and treatment duration is matched by fluconazole (Grading of recommendation A; strength of evidence 1b) and itraconazole (Grading of recommendation A; strength of evidence 1b), griseofulvin is cheaper. It must be noted, however, that griseofulvin is nowadays not available in certain European countries (e.g., Belgium, Greece, Portugal, and Turkey). [source] Cumulative meta-analysis of systemic antifungal agents for the treatment of onychomycosisBRITISH JOURNAL OF DERMATOLOGY, Issue 3 2004A.K. Gupta Summary Background Onychomycosis is a common nail disease that is often chronic, difficult to eradicate, and has a tendency to recur. The most common oral therapies for dermatophyte toenail onychomycosis include terbinafine, itraconazole and fluconazole. Objectives A cumulative meta-analysis of the randomized controlled trials (RCTs) for antimycotic agents was performed to determine whether the pooled estimate of the cure rates has remained consistent over the years. Furthermore, for each agent we compared the overall meta-analytical average of both mycological and clinical response rates of RCTs vs. open studies. Methods We searched MEDLINE (1966 to November 2002) for relevant studies evaluating the efficacy of the oral antifungal agents terbinafine, itraconazole (pulse or continuous), fluconazole and griseofulvin for treating dermatophyte toenail onychomycosis. Studies included in this meta-analysis required a standard accepted dosage regimen, treatment duration and follow-up period. To determine the cumulative meta-analytical average, studies were sequentially pooled by adding one study at a time according to the date of publication (i.e. earliest to the most recent). Results There were 36 studies included in the analyses. For RCTs the change in efficacy of mycological cure rates from the first trial to the overall cumulative meta-average for each drug comparator is as follows (with 95% confidence interval): terbinafine, 78 ± 6% (n = 2 studies, 79 patients) to 76 ± 3% (n = 18 studies, 993 patients) (P = 0·68); itraconazole pulse, 75 ± 10% (n = 1 study, 20 patients) to 63 ± 7% (n = 6 studies, 318 patients) (P = 0·25); itraconazole continuous, 63 ± 5% (n = 1 study, 84 patients) to 59 ± 5% (n = 7 studies, 1131 patients) (P = 0·47); fluconazole, 53 ± 6% (n = 1 study, 72 patients) to 48 ± 5% (n = 3 studies, 131 patients) (P = 0·50); and griseofulvin, 55 ± 8% (n = 2 studies, 109 patients) to 60 ± 6% (n = 3 studies, 167 patients) (P = 0·41). The cumulative meta-analytical average of mycological cure rates when comparing RCTs vs. open studies was: terbinafine, 76 ± 3% (n = 18 studies, 993 patients) vs. 83 ± 12% (n = 2 studies, 391 patients) (P = 0·0028); itraconazole pulse, 63 ± 7% (n = 6 studies, 318 patients) vs. 84 ± 9% (n = 3 studies, 194 patients) (P = 0·0001); and fluconazole, 48 ± 5% (n = 3 studies, 131 patients) vs. 79 ± 3% (n = 3 studies, 208 patients) (P = 0·0001). Conclusions The cumulative meta-analysis of cure rates for RCTs suggests that over time, as new RCTs have been conducted, the efficacy rates have remained consistent. The efficacy rates of open studies are substantially higher compared with RCTs and may therefore overestimate cure rates. [source] Benzodiazepines in epilepsy: pharmacology and pharmacokineticsACTA NEUROLOGICA SCANDINAVICA, Issue 2 2008J. Riss Benzodiazepines (BZDs) remain important agents in the management of epilepsy. They are drugs of first choice for status epilepticus and seizures associated with post-anoxic insult and are also frequently used in the treatment of febrile, acute repetitive and alcohol withdrawal seizures. Clinical advantages of these drugs include rapid onset of action, high efficacy rates and minimal toxicity. Benzodiazepines are used in a variety of clinical situations because they have a broad spectrum of clinical activity and can be administered via several routes. Potential shortcomings of BZDs include tolerance, withdrawal symptoms, adverse events, such as cognitive impairment and sedation, and drug interactions. Benzodiazepines differ in their pharmacologic effects and pharmacokinetic profiles, which dictate how the drugs are used. Among the approximately 35 BZDs available, a select few are used for the management of seizures and epilepsy: clobazam, clonazepam, clorazepate, diazepam, lorazepam and midazolam. Among these BZDs, clorazepate has a unique profile that includes a long half-life of its active metabolite and slow onset of tolerance. Additionally, the pharmacokinetic characteristics of clorazepate (particularly the sustained-release formulation) could theoretically help minimize adverse events. However, larger, controlled studies of clorazepate are needed to further examine its role in the treatment of patients with epilepsy. [source] | ||||||||||
