Influence of dietary habits on depression among patients with rheumatoid arthritis: A cross-sectional study using KURAMA cohort database.

ABSTRACT:

Objective

Although mental disorder is one of the most common comorbidities of rheumatoid arthritis (RA) and is known as a critical influence on RA remission rates, there is little knowledge regarding a possible therapeutic strategy for depression or anxiety in a RA population. Most recently, clinical evidence of dietary improvement for depression has emerged in a general population, but the relationship between dietary habits and mental disorder has not been investigated in RA. The purpose of this study is to elucidate clinical associations between mental disorder (depression/anxiety), dietary habits and disease activity/physical function in patients with RA.

Methods

A cross-sectional study was performed with 267 female outpatients from the KURAMA database. Using the Hospital Anxiety and Depression Scale (HADS), we classified the participants into three groups by depression state, and their characteristics were compared. Using the 20-items on the self-reported food frequency questionnaire, we investigated the relationship between dietary habits and depression or anxiety, adopting a trend test and a multivariate standardized linear regression analysis for the HADS score of depression or that of anxiety as a dependent variable.

Results

According to the classified stage of depression, current disease activity (DAS28-CRP: 28-Joint RA Disease Activity Score-C-reactive protein) and the health assessment questionnaire disability Index (HAQ-DI) were significantly increased. Trend analyses revealed that the depression score was inversely associated with the consumption of three food (fish, vegetables and fruit) out of twenty as was the anxiety score with only fish intake. Furthermore, multiple linear regression analysis revealed that the depression score was negatively associated with frequent fish intake (≥ 3 times per week) (Estimate -0.53, p = 0.033), HAQ-DI score within normal range (Estimate -0.88, p ≤ 0.001) and MTX use (Estimate -0.60, p ≤ 0.023). For the anxiety score, multivariate analysis showed similar but not significant associations with variables except for HAQ-DI score.

Conclusions

In a RA population, both depression and anxiety had a significant and negative association with HAQ-DI score, and depression rather than anxiety had negative association with frequent fish intake. Modification of dietary habits such as increased fish consumption may have a beneficial effect on the depression state in RA patients.

Project description:BackgroundPatients with rheumatoid arthritis (RA), who suffer from impaired physical function and fatigue, may have difficulties with grocery shopping and preparing meals. Also, to improve symptoms, patients often experiment with diets but seldom consult a dietitian. Although this could lead to a nutritiously deprived diet, an up-to-date, thorough description of the nutrient intake in Swedish patients with RA is absent. Here, we investigated the habitual dietary energy and nutrient intake in patients with RA living in southwestern Sweden.Materials and methodsThree-day food records performed at two time points during the ADIRA (Anti-inflammatory Diet In Rheumatoid Arthritis) trial, were used. The intake of energy and nutrients was analyzed using The Swedish Food Composition Database.ResultsA total of 62 participants (50 females, 12 males) were included in the study, where 18 participants completed one 3-day food record and 44 participants completed two 3-day food records. Median (IQR) intake of total fat was above or in the upper range of recommendations (females: 37.1 [32.5, 41.7] energy percent (E%), and males: 40.3 [37.5, 42.9] E%). Median (IQR) intake of saturated fatty acids exceeded recommendations (females: 14.9 [12.5, 17.0] E% and males: 15.4 [12.2, 17.0] E%), while median (IQR) carbohydrate and fiber intakes were below recommendations (females: 41.7 [36.3, 45.4] E% and 17.2 [12.8, 20.9] g, respectively, and males: 38.8 [35.2, 40,3] E% and 18.5 [15.7, 21.0] g, respectively). The reported intake of other macronutrients was in line with recommendations. For several micronutrients, e.g., vitamin A and D, folate, and calcium, median intake was below recommended intake. Vitamin A intake was especially low and did not reach lower intake level (LI) for 14 and 17% of females and males, respectively. For females, about 10% did not reach LI for vitamin D, calcium, and riboflavin.ConclusionWe found that patients with RA residing in southwestern Sweden reported a high intake of saturated fatty acids and low intake of fiber and several micronutrients.Clinical trial registration[https://clinicaltrials.gov/ct2/show/NCT02941055?term=NCT02941055&draw=2&rank=1], identifier [NCT02941055].

Project description:OBJECTIVES:Previous research showed that depression is common in rheumatoid arthritis (RA). However, the prevalence very much depends on different assessment tools and sociocultural differences, respectively. The main study aim and research question was to investigate the proportion of depressive symptoms in Austrian female patients with RA. SETTING:A nationwide multicentre study with seven secondary care centres all over Austria (hospital-based rheumatological outpatient clinics and private practices). PARTICIPANTS:319 patients with RA and 306 healthy controls (HCO), all female Caucasians, were asked to complete a Beck's Depression Inventory-Fast Screen (BDI-FS). Patients and HCO were ?18 years. Patients had to fulfil the 2010 classification criteria for RA. In addition, disease activity, disability, medication, drinking of alcoholic beverages, smoking and occupational status were evaluated. PRIMARY AND SECONDARY OUTCOME MEASURES:A BDI-FS cut-off value of ?4, per definition, indicates the presence of a depressive symptomatology. RESULTS:The return rate of questionnaires was high: 235/319 (73.7%) in patients with RA and 180/306 (58.8%), ending up with 392 complete questionnaires from 223 patients with RA (69.9%) and 169 HCO (55.2%). The BDI-FS was significantly higher in patients with RA (median BDI-FS 2 (IQR 0-4) vs median 1 (IQR 0-2) in HCO, p<0.001). BDI-FS scores from ?4, which by definition indicate depression, were found in 29.6% of patients with RA and 12.4% of HCO (p<0.001). Depressive symptoms were strongly associated with disease activity (Clinical Disease Activity Index, p<0.001) and disability (Health Assessment Questionnaire, p<0.005). No association of depressive symptoms with age, alcohol consumption, smoking, occupational status or use of medication was found. CONCLUSIONS:One-third of female patients with RA showed depressive symptoms. Depression was significantly higher in female patients with RA than in female HCO and was strongly associated with disease activity and disability. It would be of interest to address the same question in male participants.

Project description:IntroductionLimited data are available to explain nonadherence to methotrexate (MTX) therapy in patients with rheumatoid arthritis (RA). Better understanding of patterns of MTX use and reasons for nonadherence may help identify patients who would benefit from alternative RA treatments and potentially aid in developing strategies to increase overall adherence. The purpose of this study was to assess patients' self-reported adherence to MTX and to identify reasons for nonadherence.MethodsPatient panel members in the US self-reporting a diagnosis of RA of ?3 months' and current MTX use of ?4 weeks' duration, with or without concomitant use of another RA prescription medication, participated in this cross-sectional, web-based survey.ResultsThe sample population (251 MTX monotherapy, 250 MTX combination therapy) was predominantly female, white, non-Hispanic, and educated; 48% were 18-44 years-old, 47% had medical comorbidities, 66% were first diagnosed with RA ?5 years earlier, 51% reported MTX use of <1 year, and 83% reported oral MTX use. Forty-two percent reported not taking MTX exactly as prescribed. Reasons for nonadherence included forgetting to take it (33%), not needing it when feeling well (24%), and concern about long-term safety (24%). Among nonadherent patients, 53% took smaller doses, 52% skipped doses, and 6% reported other nonprescribed ways of taking MTX. Younger age, male sex, and shorter duration of MTX use were associated with poorer self-reported adherence. Compared with monotherapy patients, combination therapy patients, particularly those taking ?2 other RA prescriptions, were less likely to report high adherence.ConclusionNearly half the sample reported poor MTX adherence because they forgot to take it, thought it was not needed when they felt well, or had long-term safety concerns. Patients taking ?2 other RA prescription medications were less likely to report good adherence. Reducing treatment burden without sacrificing efficacy may be a strategy worth evaluating.

Project description:PurposeRheumatoid arthritis (RA) is an often debilitating autoinflammatory disease. Patients with rheumatoid arthritis are often troubled by co-occurring depression or other psychological manifestations. RA patients have a variety of treatment options available, including biologicals that inhibit cytokines or immune cells. If these cytokines influence the psychological symptoms, then the use of cytokine inhibitors should modulate these symptoms.MethodsA cohort of 209 individuals was recruited. This group included 82 RA patients, 22 healthy subjects, 32 depressed control subjects, and 73 subjects with systemic lupus erythematosus. Of the RA patients, 51% were on a biological therapeutic. ELISA was used to measure cytokine levels. A variety of psychological assessments were used to evaluate depression, anxiety, sleep, fatigue, and relationship status. Clinical values were obtained from medical records.ResultsIL-10 concentration was associated with depressive symptoms in the RA patients, healthy controls, and the lupus patients. In the patients with primary depression, depressive symptoms were associated with IL-6 and TNF-alpha. In RA patients, Tocilizumab use was associated with decreased depressive symptoms. 14 RA patients who were not using biologicals began using them by a one-month follow-up. In these patients, there was no significant change to any value except for fatigue.ConclusionsA variety of both biological and social factors influences depressive symptoms in RA. IL-10 and IL-6 are likely to be involved, since IL-10 concentration was associated with depression and Tocilizumab decreased depressive symptoms in the RA patients. The roles of these cytokines are different in RA and lupus, as high IL-10 in RA is associated with increased depressive symptoms, but high IL-10 in the lupus patients is associated with decreased depression. IL-6 was also associated with depressive symptoms in the patients with primary depression. These results strongly indicate that disease activity, including cytokine levels, has a strong impact on depressive symptoms.
