A Multicenter Analysis of the Use of Complementary and Alternative Medicine in Turkish Patients with Rheumatoid Arthritis

Prevalence and Factors Associated with Concomitant Chinese Medicine Use by Rheumatoid Arthritis Patients in A Multi-Ethnic Asian Population

OBJECTIVE

To determine the prevalence, factors associated with and patterns of concomitant Chinese medicine (CM) with Western treatment use among patients with rheumatoid arthritis (RA) in a tertiary referral centre (Singapore General Hospital) in Singapore.

METHODS

We conducted a cross-sectional interviewer-administered survey of a consecutive sample of patients with RA in Singapore General Hospital centre regarding their CM use including data on patient demographics, disease characteristics, concomitant use of CM and reasons, concerns and disclosure patterns from March to August 2015. Univariate and multivariate logistic regression analyses were performed to determine the associations of CM use.

RESULTS

Prevalence of CM use among the 258 patients surveyed (male: female 42: 216; Chinese: Malay: Indian 191: 29: 34; mean age: 61 years; mean duration of RA: 10 years) was 46.1% (119/258). On multivariate analysis, Chinese ethnicity (OR, 95% CI: 4.11, 1.49-11.36), Chinese speakers (OR, 95% CI: 2.35, 1.03-5.54), middle-income group (OR, 95% CI: 2.53, 1.01-6.31) and greater learned helplessness (OR, 95% CI: 1.13, 1.04-1.22) were significantly associated with CM use. More CM users disclosed their CM use to CM physicians (87.3%, 96/110), sought advice from them on treatment interactions (59.4%, 57/96) and how best to combine treatments (49.0%, 47/96) than did so with rheumatologists (42.0%, 50/119; 40.0%, 20/50; and 42.0%, 21/50, respectively). Forty-two percentage (29/69) of patients who concealed CM use from rheumatologists because their rheumatologists did not specifically enquire about CM use.

CONCLUSIONS

Concomitant CM use among patients with RA treated in a tertiary referral centre in Singapore is high but voluntary disclosure is low. The associations identified can help doctors identify and enquire about CM use, minimizing potential adverse interactions.

Association of complementary and integrative therapy use and symptoms among Turkish patients with familial Mediterranean fever

OBJECTIVE

This study explored the correlations between the use of complementary and integrative therapies (CITs) and symptoms among Turkish patients with familial Mediterranean fever (FMF).

METHODS

This is a cross-sectional and descriptive study. The study was conducted with 1119 FMF patients who were registered to the social networking site for Behcet's and the FMF Patients Association (Befemder) in Turkey, between January 2018 and February 2019. Data were collected using an online survey, for which a three-part questionnaire was created using a Google form. Descriptive statistics, chi-square test and logistic regression analysis were used to analyze the data.

RESULTS

It was determined that 53.2% of the individuals who participated in the research used various forms of CITs and that 32.8% used vitamin and mineral supplements (calcium, iron, and vitamin B12, C and D), 25.0% used nutritional supplements (fish oil and honey), and 24.6% used oral herbs (ginger, turmeric, green tea and rosemary) and mind-body methods (relaxation, respiration exercise and meditation). It was determined that the percentage of participants that used CITs was higher among women (odds ratio [OR] = 1.825; 95% confidence interval [CI] 1.421-2.344), those with joint pain (OR = 1.385; 95% CI 1.047-1.832), those with difficulty breathing (OR = 1.323; 95% CI 1.031-1.697), those with gastrointestinal symptoms (OR = 1.405; 95% CI 1.089-1.814) and those who had a family member with FMF (OR = 1.437; 95% CI 1.115-1.851).

CONCLUSION

More than half of the individuals used at least one type of CIT for symptom control.

The quality of online consumer health information at the intersection of complementary and alternative medicine and arthritis

BACKGROUND

Complementary and alternative medicine (CAM) use is prevalent among patients living with arthritis. Such patients often seek information online, for the purpose of gaining a second opinion to their healthcare provider or even self-medication. Little is known about the quality of web-based consumer health information at the intersection of CAM and arthritis; thus, investigating the quality of websites containing this information was the purpose of this study.

METHODS

Four unique search terms were searched on Google across four English-speaking countries. We assessed the first 20 results of each search, including them if they contained CAM consumer health information for the treatment and/or management of arthritis. Eligible websites were assessed in duplicate using the DISCERN instrument, which consists of 16-items designed to assess quality.

RESULTS

Of total of 320 webpages, 239 were duplicates, and a total of 38 unique websites were deemed eligible and assessed using the DISCERN instrument. The mean summed  DISCERN scores across all websites was 55.53 (SD = 9.37). The mean score of the overall quality of each website was 3.71 (SD = 0.63), thus the majority of websites are ranked as slightly above 'fair' quality.

CONCLUSION

Eligible websites generally received scores better than 'moderate' in terms of overall quality. Several shortcomings included a lack of transparency surrounding references used and underreporting of risks associated with treatment options. These results suggest that health providers should be vigilant of the variable quality of information their patients may be accessing online and educate them on how to identify high quality resources.

Use of complementary and alternative medicine in patients with ankylosing spondylitis

OBJECTIVE

Some studies have shown that the use of complementary and alternative medicine (CAM) is common in patients with chronic painful conditions, such as ankylosing spondylitis (AS). This study aimed to determine the prevalence and types of CAM usage in patients with AS and to evaluate the impact of treatment adherence and beliefs about medicines on CAM usage.

METHODS

This study has a descriptive design. A total of 140 patients with AS were included. The treatment adherence of the patients was evaluated using the Morisky Green Levine Medication Adherence Scale. The Beliefs about Medicines Questionnaire (BMQ-T) was used to assess patients' beliefs about medicines.

RESULTS

Previous or current CAM usage was stated by 40% of the patients. It has been found that CAM usage was significantly high (p<0.05) in patients who were married, older, and diagnosed at older ages. The difference between patients' beliefs about medicines and CAM usage was not statistically significant (p>0.05). The BMQ-T scores were significantly different in terms of the patients' treatment adherence (p<0.05).

CONCLUSION

This study showed that approximately half of the patients with AS were using 1 CAM method. Furthermore, medication adherence and patients' beliefs about medicines did not have any impact on CAM usage, but the patients' beliefs about medicines affected treatment adherence.

Determination of Use of Alternative Medicine Methods in Patients With Ankylosing Spondylitis

This study aimed to examine complementary and alternative medicine (CAM) use among patients with ankylosing spondylitis (AS) who had or who had not received treatment with biological agents; the study also aimed to determine the types of CAM methods used by these patients. This is a comparative and cross-sectional study. This research was conducted at a rheumatology outpatient clinic of a university hospital in Turkey. A total of 120 patients who had (n = 60) and had not (n = 60) received therapy with biological agents participated in this study. A patient identification form and a questionnaire prepared by the researchers were used to collate the study data. This study found that the most commonly used method among patients who did not receive biological therapy was thermal facilities, at a rate of 28.3%; and that the most commonly used method among patients who did receive biological therapy was the use of thermal facilities, at a rate of 25%. No significant difference was found between patients who had received and patients who had not received biological therapy in terms of age and disease duration. Information was provided by health professionals to the patients concerning frequently used CAM modalities.

Use of traditional and complementary medicine for musculoskeletal diseases

Background/aim

We aimed to determine the prevalence of traditional and complementary medicine (TCM) use among patients with musculoskeletal disorders (MSDs) and to examine the methods used, frequency, and experienced benefits of therapies; the reasons for using TCM; and the sources of information about therapies. We also compared demographic characteristics of users and nonusers of TCM.

Materials and methods

The descriptive study was conducted with 839 patients who attended the physical therapy and rehabilitation units of 3 public hospitals between September 2014 and March 2015. A self-administered questionnaire including demographic characteristics, medical history, and details of TCM use was applied.

Results

Of the 839 individuals in the study (592 female, 247 male; mean age 48.9 ± 13.0 years), 35.4% reported using TCM. There was no significant statistical difference between users and nonusers in terms of age, gender, body mass index, socioeconomic status, or educational level (P > 0.05). The disease duration of TCM users was significantly higher than that of nonusers (P < 0.05). The most commonly used TCM methods were balneotherapy (31%), herbal therapies (30%), wet cupping (22.2%), and massage-manipulation methods (21.2%). Of TCM users, 75.1% were satisfied.

Conclusion

The prevalence of TCM use and satisfaction levels are high in patients with MSDs. Physicians should be well informed about TCM methods and raise the awareness of patients to prevent improper use of TCM.

Natural Product Dietary Supplement Use by Individuals With Rheumatoid Arthritis: A Scoping Review

OBJECTIVE

Natural product dietary supplements (NDS), defined as non-mineral, non-vitamin, ingested, natural product-derived, substances, are the most frequently used complementary and alternative medicine modality in the US, with musculoskeletal disease being the most frequent reason for their use. Because NDS usage is frequently unreported, and patients with RA may be at higher risk for NDS-related side effects due the underlying nature of the disease and frequent use of complex pharmaceutical regimens, a scoping review of the literature was undertaken to examine population-based patterns of NDS use for RA self-management.

METHODS

Using guidelines for scoping reviews, Allied and Complementary Medicine, the Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, Embase, Ovid/Medline, and Web of Science databases were searched to identify references presenting primary data related to the prevalence or patterns of use of NDS in RA populations.

RESULTS

Twenty-three studies, which were published between 1980 and 2015 and conducted in 11 countries, met the inclusion criteria. The overall prevalence of NDS use in patients with RA was 47% worldwide and did not differ by geographic region. On average, 47% of patients found NDS to be effective and 13% reported adverse side effects, with only 30% informing their physicians about the use of NDS, which in a majority of cases were used concomitantly with RA pharmaceuticals. Marine oils, glucosamine, vinegar, and chondroitin were among the most commonly reported NDS worldwide.

CONCLUSION

Given the apparent communication gap between patients and providers regarding NDS use and higher potential risks associated with this usage in RA, ongoing surveillance of population-based practices may help facilitate RA management and direct future NDS research.

A 4-year non-randomized comparative phase-IV study of early rheumatoid arthritis: integrative anthroposophic medicine for patients with preference against DMARDs versus conventional therapy including DMARDs for patients without preference

BACKGROUND

While disease-modifying antirheumatic drugs (DMARDs) are a mainstay of therapy for rheumatoid arthritis (RA), some patients with early RA refuse DMARDs. In anthroposophic medicine (AM), a treatment strategy for early RA without DMARDs has been developed. Preliminary data suggest that RA symptoms and inflammatory markers can be reduced under AM, without DMARDs.

PATIENTS AND METHODS

Two hundred and fifty-one self-selected patients aged 16-70 years, starting treatment for RA of <3 years duration, without prior DMARD therapy, participated in a prospective, non-randomized, comparative Phase IV study. C-patients were treated in clinics offering conventional therapy including DMARDs, while A-patients had chosen treatment in anthroposophic clinics, without DMARDs. Both groups received corticosteroids and nonsteroidal anti-inflammatory drugs (NSAIDs). Primary outcomes were intensity of RA symptoms measured by self-rating on visual analog scales, C-reactive protein, radiological progression, study withdrawals, serious adverse events (SAE), and adverse drug reactions in months 0-48.

RESULTS

The groups were similar in most baseline characteristics, while A-patients had longer disease duration (mean 15.1 vs 10.8 months, p<0.0001), slightly more bone destruction, and a much higher proportion of women (94.6% vs 69.7%, p<0.0001). In months 0-12, corticosteroids were used by 45.7% and 81.6% (p<0.0001) and NSAIDs by 52.8% and 68.5% (p=0.0191) of A- and C-patients, respectively. During follow-up, both groups not only had marked reduction of RA symptoms and C-reactive protein, but also some radiological disease progression. Also, 6.2% of A-patients needed DMARDs. Apart from adverse drug reactions (50.4% and 69.7% of A- and C-patients, respectively, p=0.0020), none of the primary outcomes showed any significant between-group difference.

CONCLUSION

Study results suggest that for most patients preferring anthroposophic treatment, satisfactory results can be achieved without use of DMARDs and with less use of corticosteroids and NSAIDs than in conventional care.

LIMITATION

Because of the non-randomized study design, with A-patients choosing anthroposophic treatment, one cannot infer how this treatment would have worked for C-patients.

Characteristics of traditional Chinese medicine use in patients with rheumatoid arthritis in Taiwan: A nationwide population-based study

ETHNOPHARMACOLOGICAL RELEVANCE

Large-scale study of traditional Chinese medicine (TCM) usage among patients with rheumatoid arthritis (RA) is lacking. The aim of this study is to evaluate the TCM usage among RA patients in Taiwan.

MATERIALS AND METHODS

We examined the "registry for catastrophic illness patient dataset" of the National Health Insurance Research Database (NHIRD; n=23 million people) in Taiwan. Patients (n=25,263) newly diagnosed as RA in 2001-2009 were included and then followed-up until the end of 2011. Based on the medical utilization, they were further categorized into TCM users (n= 6891; 27.3%) and non-TCM users (n=18,372; 72.7%). The demographic data and core prescription patterns of the TCM users were analyzed.

RESULTS

Compared to non-TCM user, TCM users were younger (mean age: 49.6 versus 54.0 years), had a higher female/male ratio (82.7%/17.3% versus 74.1%/25.9%), resided in more urbanized area. Herbal remedies were the most commonly used therapeutic approach (76.4%), followed by combining acupuncture (21.1%). The frequency of outpatient visits in TCM users was higher across all disease categories except circulatory system. The most commonly prescribed formula and herb was Shang-Jong-Shiah-Tong-Yong-Tong-Feng-Wan and Rhizoma Corydalis, respectively. The analysis of core pattern revealed that Dang-Gui-Nian-Tong-Tang, Shu-Jing-Huo-Xie-Tang, Gui-Zhi-Shao-Yao-Zhi-Mu-Tang, Myrrha and Olibanum, were among the most frequently used combinations. RA patients who had anxiety and depression, allergic rhinitis, osteoporosis, menstrual disorder, and menopausal syndrome were prone to have more TCM visits compared to non-TCM users.

CONCLUSIONS

Our population-based study revealed the high prevalence and specific usage patterns of TCM in the RA patients in Taiwan. The information could be used for further pharmacological investigation and clinical trials.
