In this study, a total of 100 eligible patients were surveyed. The mean age of the participating patients was 45.15 years (range: 14 - 83 years), and 84% were females. Diagnoses included 49 RA patients (49%), 31 SLE patients (31%), 11 scleroderma patients (11%), 5 vasculitis patients (5%), 1 ankylosing spondylitis patient (1%), 2 reactive arthritis patients (2%), 1 dermatomyositis patient (1%), 1 polymyositis patient (1%), 2 osteoarthritis patients (2%), and 1 low back pain patient (1%). The mean duration of the diseases was 8.26 months (range 0 - 35 months).
Eighty-seven patients (87%) reported using at least one form of CAM, among which 74 (85%) were females. Dietary supplements comprised the most frequent category of CAM among the patients (40%), followed by specific diet (36%). Fish oil (25%), massage therapy (20%), deep breathing exercise and meditation (16%), herbal remedies (11%), acupuncture (11%), homeopathy (4%), yoga (4%), and hypnotherapy (1%) were also used by the patients.
Channels through which the participants were introduced to CAM were: family physicians in 53 cases (26.6%), rheumatologists in 20 cases (10%), pharmacists in 3 cases (1%), naturopaths in 5 cases (2%), homeopaths in 2 cases (1%), and other ways in 116 cases (58%).
The most frequent reasons reported for discontinuing CAM and/or changing to another form of CAM were: inadequate response in 75 cases (63%), fear of possible adverse effects in 18 cases (15%), presence of actual adverse effects in 14 cases (12%), scarce results in 6 cases (5%), and being advised by a non-conventional medicine practitioner in 5 cases (4%).
Twenty-nine (33.3%) CAM users and 4 (30.8%) non-CAM users were smokers (P = 0.29). The mean age of CAM users and non-CAM users was 45.5 and 42.4 years, respectively (P = 0.61). The mean duration of the disease in CAM users was 8.64 months and in non-users was 6.51 months (P = 0.093). The mean education level of CAM users was 7.2 years and in non-CAM users was 6.3 years (P = 0.16). Seventy-six (87.4%) users and 10 (76.9%) non-users were married (P = 0.12). Fifty-two (89.7%) patients with more than 5 months disease duration were CAM users, and also 35 (83.3 %) of the patients with less than 5 months disease duration were CAM users, with no significant difference between the two groups (P > 0.05). Other factors such as age, sex, smoking, marital status, occupational status, living place, and birthplace were not significantly associated with CAM usage (P > 0.05).
The patients were divided into three age groups: 0 - 25 years, 26 - 50 years, and 51 - 83 years. Forty-six cases (53%) of CAM users belonged to the second group, 33 (38%) to the third group and 8 (9%) to the first group. These ratios had no noticeable contrast with non-CAM users (P > 0.05).
Eighty percent of the CAM users and all of the non-CAM users were attending the rheumatology centers regularly. Seventeen patients who had dropped out of follow-ups for more than one year and 70 (84.3%) regular visitors were CAM users. However, there was no significant role for CAM using in attending regular visits (P = 0.08).
Based on our results, the most common CAM remedy used in RA patients was a supplementary diet such as vitamins (40.8%), and in SLE it was a specific diet that was recommended by non-experts (37.8%).
