Both topical corticosteroids induced a significant reduction in skin thickness, as compared with SDZ ASM 981 1% cream and vehicle, which were shown to be equivalent. The difference in skin thickness (measured by ultrasound examination) between patients treated with SDZ ASM 981 1% cream and those receiving either of the two topical steroids was significant from day 8 onwards. Histological analysis performed at day 29 showed significant epidermal thinning with topical steroids compared with SDZ ASM 981 1% cream or the vehicle. Conclusion The lack of atrophogenic properties of SDZ ASM 981 1% cream in this short-term study demonstrates its potential as long-term treatment for inflammatory skin diseases, thus overcoming a major drawback of topical steroids. This may also be important for the treatment of children, and sensitive areas of skin, such as the face and skin-folds.
Cholinesterase inhibitor treatment may offer continued therapeutic benefit for up to 2 years in patients with moderate AD. Although both drugs performed similarly on cognition and behaviour, rivastigmine may provide greater benefit in activities of daily living and global functioning.
In COPD patients requiring combination bronchodilator treatment, the addition of formoterol to regular ipratropium treatment is more effective than the addition of salbutamol.
Oxcarbazepine treatment over 6 months does not display any differential effects on cognitive function and intelligence in children and adolescents with newly diagnosed partial seizures relative to standard antiepileptic drug therapy. No impairment in cognitive function was observed in any treatment group over a 6-month period.
A randomized double-blind trial evaluated the efficacy and tolerability of rivastigmine, an inhibitor of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE), and donepezil, an AChE-selective inhibitor, in patients with Alzheimer's disease over a 2-year period. A retrospective analysis showed differential responses to cholinesterase inhibitors (ChE-Is) in patients younger than 75 years. This analysis investigated the effect of BuChE genotype on response to ChE-I therapy in these patients. In a retrospective analysis, patients younger than 75 who had consented to pharmacogenetic analysis were divided into groups according to BuChE genotype. Efficacy measures were the Severe Impairment Battery (SIB), Neuropsychiatric Inventory (NPI), Global Deterioration Scale (GDS), Mini-Mental State Examination (MMSE) and the Alzheimer's Disease Cooperative Study-Activities of Daily Living Scale (ADCS-ADL). Changes on efficacy parameters were calculated for rivastigmine-treated and donepezil-treated patients in both groups. Of 114 (34.1%) patients younger than 75 who were successfully assessed for BuChE genotype, 76 (66.7%) were homozygous for wild-type BuChE, and 38 (33.3%) carried at least one BuChE K-variant allele. Wild-type BuChE carriers showed significantly greater responses to rivastigmine than to donepezil on the SIB, ADCS-ADL, GDS and NPI. No significant between-treatment differences in efficacy were observed in BuChE K-variant carriers, although adverse events were more frequent in rivastigmine-treated patients. In this retrospective analysis, Alzheimer's disease patients younger than 75 with wild-type BuChE exhibited differential efficacy to rivastigmine, while BuChE K-variant carriers experienced similar long-term treatment effects with both agents. These differences may reflect rivastigmine's ability to inhibit BuChE and AChE.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
