Comparative Study
Comparison of acarbose and metformin therapy in newly diagnosed type 2 diabetic patients with overweight and/or obesity.
To compare the efficacy of acarbose and metformin in overweight and/or obese patients with newly diagnosed type 2 diabetes mellitus (T2DM). ⋯ Twenty-four weeks of therapy with acarbose and metformin induced similar reductions in HbA1c and body weight, but acarbose showed superior efficacy in improving islet α-cell function compared with metformin in overweight/obese patients with newly diagnosed T2DM. However, more large-sample, multicenter, randomized controlled trials are needed to evaluate the efficacy, safety, cost-effectiveness, and glycemic variability of the two drugs.

Cyclooxygenase (COX) 1 and 2 enzyme up-regulation is involved in the pathogenetic process of actinic keratosis (A.K.) and non-melanoma skin cancers. Diclofenac, a non-steroidal anti-inflammatory (N.S.A.I.D.) drug, is used as topical treatment of A.K. Piroxicam is a N.S.A.I.D. characterized by a high COX-1 inhibition activity. ⋯ Our experience suggests that 6 month topical piroxicam 0.8% is efficacious and well tolerated in A.K. Clinical efficacy is maintained 1 year post-treatment. The main limitation of our study is that it was an open label non-controlled trial. Future controlled trials are warranted in order to compare the efficacy and tolerability of this topical piroxicam preparation with standard treatments in the management of A.K.

Many patients with type 2 diabetes mellitus (T2DM) require insulin therapy. If basal insulin fails to achieve glycemic control, insulin intensification is one possible treatment intensification strategy. We summarized clinical data from randomized clinical trials designed to compare the efficacy and safety of basal-bolus and premixed insulin intensification regimens. ⋯ Of the four trials that reported a significant difference between regimens in bodyweight change, two favored basal-bolus therapy and two favored premixed insulin. Thus, on a population level, neither basal-bolus therapy nor premixed insulin showed a consistent advantage in terms of glycemic control, hypoglycemic risk, or bodyweight gain. It is therefore recommended that clinicians should adopt an individualized approach to insulin intensification - taking into account the benefits and risks of each treatment approach and the attitude and preferences of each patient - in the knowledge that both basal-bolus and premixed regimens may be successful.
