Review Meta Analysis
Randomized, vehicle-controlled trials of topical 5-fluorouracil therapy for actinic keratosis treatment: an overview.
Actinic keratoses are common in older individuals and topical immunotherapy is an important treatment when multiple lesions are present. To assess the efficacy of 5-fluorouracil in treating actinic keratoses, a systematic review of randomized, vehicle-controlled trials was performed. ⋯ After 4 weeks of treatment, total clearance and mean lesion count reduction were 52.6 and 90.2% in the treatment group versus 0.85 and 28.3% in the vehicle group, respectively. Topical 5-fluorouracil is efficacious in treating actinic keratoses; however, vehicle responses warrant further investigation of study design and disease severity scales.

Crohn's disease and ulcerative colitis are chronic, relapsing inflammatory disorders of the GI tract. In both Crohn's disease and ulcerative colitis, leukocytic infiltration of the mucosa is associated with epithelial damage. ⋯ Vedolizumab targets a subset of the CAMs blocked by natalizumab and is currently in Phase III trials to study its efficacy and safety in patients with inflammatory bowel disease. Here, we discuss the current treatment options available for patients with Crohn's disease or ulcerative colitis, the history of CAM inhibitors, the current state of development of vedolizumab and its future role in inflammatory bowel disease, if approved by regulatory agencies.
