title: [Effectiveness of Formica rufa and autologous blood injection in patients with ankylosing spondylitis: a double-blind randomized study].
abstract: While complementary medicine and homeopathy is becoming an increasingly prominent part of the health care practices, there is a lack of controlled studies concerning their effectiveness. In our study, we wanted to answer the question whether a combination of Formica rufa D6 and reinjection of the patient's own blood is superior to injection of placebo. 104 patients with ankylosing spondylitis entered a prospective, randomized, double-blind study. During four weeks they received twice weekly either 1 ml of Formica rufa D6 in combination with 0.5 ml of blood or 1.5 ml NaCl intramuscular. Before and after therapy, mobility, thoracic excursion and doctor's overall assessment were measured in addition to patient's health status, using a German version of the Arthritis Impact Measurement Scales, before and after therapy as well as four, twelve, and twenty-four weeks later. We were not able to detect any statistical difference between treatment and placebo group in any of the parameters measured. Therefore, the therapy under study may not be regarded effective.
