Efficacy of Micro-Pulse Steroid Therapy as Induction Therapy in Patients With Polymyalgia Rheumatica

2014-08-27 03:19:10 | BioPortfolio


The study will examine the efficacy of a single intramuscular injection of betamethasone dipropionate/betamethasone sodium phosphate at the dose of 20mg/8mg (injection volume 4 ml) as an induction therapy in patients with polymyalgia rheumatica. Twenty patients will be randomized to receive an injection of betamethasone or placebo (isotonic NaCl solution) immediately after diagnosis. Both groups will receive the standard-of-care steroid therapy, starting from 10 mg of prednisone every day (qd), tapered down by 2.5 mg monthly if the disease is not active (scheduled monthly follow-ups by a rheumatologist). Primary outcome measures: the total cumulative dose of glucocorticosteroids and disease duration.

Medical and Biotech [MESH] Definitions

Hypertonic sodium chloride solution. A solution having an osmotic pressure greater than that of physiologic salt solution (0.9 g NaCl in 100 ml purified water).

A subclass of symporters that specifically transport SODIUM CHLORIDE and POTASSIUM CHLORIDE across cellular membranes in a tightly coupled process.

Agents that inhibit SODIUM CHLORIDE SYMPORTERS. They act as DIURETICS. Excess use is associated with HYPOKALEMIA.

Solution that is usually 10 percent glucose but may be higher. An isotonic solution of glucose is 5 percent.

A syndrome in the elderly characterized by proximal joint and muscle pain, high erythrocyte sedimentation rate, and a self-limiting course. Pain is usually accompanied by evidence of an inflammatory reaction. Women are affected twice as commonly as men and Caucasians more frequently than other groups. The condition is frequently associated with GIANT CELL ARTERITIS and some theories pose the possibility that the two diseases arise from a single etiology or even that they are the same entity.
