Lupus education for physicians and patients in a resource-limited setting Abstract Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with a wide range of manifestations and potential to affect several organ systems. Complications arise from both disease and medications especially glucocorticoids, significantly contributing to overall morbidity and mortality. SLE predominantly affects patients during their prime productive years resulting in substantial economic burden on the patient, caregivers, and society due to direct, indirect, and intangible costs. This illness burden is compounded in developing countries with limited resources due to various disparities in healthcare delivery. Physician education and practical referral and endorsement guidelines adapted to the local setting reinforce continuity and coordinated care. Likewise, patient education, self-help programs, and shared decision-making are essential best practice in the clinics. Both physician education and patient education improve overall outcomes in chronic diseases like SLE. As a developing country with very few rheumatologists and/or lupus specialists, efficient healthcare delivery for most Filipino lupus patients remains elusive. We describe our experience in confronting these challenges through development of strategies which focus on physician and patient education. Key Points • Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with a highly variable course, requiring specialized, individualized, and coordinated care by a healthcare team. • Health disparities and limited resources significantly contribute to illness burden on the patient, family, and society. • Physician education on SLE must commence at undergraduate medical school, be integrated in Internal Medicine and Pediatrics, and reinforced through specialized training in Rheumatology and related specialties. • Patient education and empowerment are integral to improving healthcare outcomes especially in a resource-limited setting.

Prevalence and risk factors associated with vertebral osteoporotic fractures in patients with rheumatoid arthritis Abstract Objectives To explore the prevalence and risk factors of osteoporosis (OP) and vertebral osteoporotic fracture (VOPF) in patients with rheumatoid arthritis (RA). Methods Anteroposterior and lateral X-ray examination of the vertebral column (T4-L4) was used for the semi-quantitative assessment of VOPF. Bone mineral density was measured by dual-energy X-ray absorptiometry. Results Of 865 RA patients, the prevalence of OP and VOPF was 33.6% and 20.2%, respectively. Patients with OP or VOPF were older, and had longer term use and a larger daily amount and cumulative dose of glucocorticoids (GCs), longer disease duration, and higher Health Assessment Questionnaire (HAQ) scores and Sharp scores than patients without OP or VOPF (P < 0.05). OP was also correlated with higher disease activity. The patients treated with GCs had higher incidences of OP and VOPF than the patients without GCs (P < 0.05). The cutoff values in the area under curve (AUC) of the daily dose or treatment course of GCs-VOPF were 9 mg and 37.5 days. Older age, female sex, and a higher Sharp score were risk factors for OP in RA patients, while higher BMI was a protective factor. Older age and a high GC daily dose were risk factors for VOPF in RA patients. Conclusions RA patients have a high prevalence of OP and VOPF. Older age, female sex, lower BMI, and higher activity and severity of RA are closely related with OP. Older age and a higher GC daily dose are risk factors for VOPF in RA patients. Key Points • Older age, female sex, lower BMI, and a higher Sharp score were risk factors for OP in RA patients. • Older age and a high GC daily dose were risk factors for VOPF in RA patients. • OP and VOPF in RA patients were correlated with longer disease duration and higher severity of RA.

Increased risks of psychiatric disorders in patients with primary Sjögren’s syndrome—a secondary cohort analysis of nationwide, population-based health claim data Abstract Introduction/objectives Primary Sjögren’s syndrome (pSS) is a chronic systemic autoimmune disease. The aim of this study was to investigate the risk of five common psychiatrist-diagnosed disorders in patients with pSS. Method Using Taiwan’s National Health Insurance Research Database, 688 patients with newly diagnosed pSS between 2000 and 2012 were identified. Two comparison cohorts were assembled, namely, 3440 patients without pSS and 1302 newly diagnosed patients with rheumatoid arthritis. The incidences of depressive disorder, anxiety disorder, bipolar disorder, sleep disorder, and schizophrenia between the pSS cohort and the comparison cohorts were compared using Poisson regression models. Results Patients with pSS exhibited a significantly higher risk of developing depressive disorder (adjusted incidence rate ratio [aIRR] = 2.11, p < 0.001), anxiety disorder (aIRR = 2.20, p < 0.001), and sleep disorder (aIRR = 1.76, p = 0.012) when compared with the non-pSS cohort. The risks of developing depressive, anxiety, and sleep disorders were also significantly increased when compared to the rheumatoid arthritis comparison cohort. When the analyses were stratified by sex, depressive disorder (aIRR = 2.10, p < 0.001), anxiety disorder (aIRR = 2.02, p = 0.001), and sleep disorder (aIRR = 1.74, p = 0.022) were found to be significantly increased in female patients with pSS. However, only anxiety disorder (aIRR = 4.88, p = 0.044) was also significantly increased in male patients with pSS. The peak age group of developing depressive disorder was 65–80 years old (aIRR = 3.46, p < 0.001). Conclusions In this retrospective cohort study based on population-based claim data, significantly increased incidences of depressive disorder, anxiety disorder, and sleep disorder were observed in patients with pSS. Key Points • Patients, particularly women, with primary Sjögren’s syndrome exhibited a significantly higher risk of developing depressive disorder, anxiety disorder, and sleep disorder. • The peak age group of developing depressive disorder was 65–80 years old.

Does symptomatic knee osteoarthritis increase the risk of all-cause mortality? Data from four international population-based longitudinal surveys of aging Abstract Objective This study aimed at examining the association between symptomatic knee osteoarthritis and all-cause mortality based on four population-based longitudinal surveys. Method Data were retrieved from the English Longitudinal Study of Aging (ELSA), the Survey of Health, Aging and Retirement in Europe (SHARE), the Korean Longitudinal Study of Aging (KLoSA), and the Indonesian Family Life Survey (IFLS). The association between symptomatic knee osteoarthritis and all-cause mortality over the 8- to 12-year follow-up period was assessed using Cox-proportional hazard models. Results In the entire sample of 59,522 participants (4823 with symptomatic knee osteoarthritis; 54,699 without symptomatic knee osteoarthritis [control group]; mean age: 61.8 years; female percentage: 55.3%), 8375 died (937 in the symptomatic knee osteoarthritis group, 7438 in the control group) during the follow-up period. Patients with symptomatic knee osteoarthritis had a higher risk of all-cause mortality than control group without adjusting for potential confounders in each survey, and the unadjusted hazard ratios (HRs) of all-cause mortality were 1.32 (95% confidence interval [CI] 1.18 to 1.47) in ELSA, 1.40 (95%CI 1.24 to 1.56) in SHARE, 1.25 (95%CI 1.06 to 1.47) in KLoSA, and 1.65 (95%CI 1.31 to 2.07) in IFLS. However, with adjustment of potential confounders, the corresponding HRs dropped to 1.07 (95%CI 0.94 to 1.20) in ELSA, 1.08 (95%CI 0.97 to 1.22) in SHARE, 0.91 (95%CI 0.77 to 1.08) in KLoSA, and 0.89 (95%CI 0.66 to 1.21) in IFLS, respectively. Conclusions In these four population-based longitudinal studies, no association between symptomatic knee osteoarthritis and increased risk of all-cause mortality was observed after adjusting for potential confounders. Key Points • This study evaluated the association between symptomatic knee OA and the risk of all-cause mortality among the participants retrieved from four large population-based longitudinal studies across the world. • No association between symptomatic knee osteoarthritis and increased risk of all-cause mortality was observed after considering potential confounders, and our findings were consistent with the results derived from four independent longitudinal studies. • The present study included four international population-based longitudinal studies, comprising both developed and developing areas, which allowed the findings to be interpreted under larger circumstance.

LncRNA GAS5 overexpression downregulates IL-18 and induces the apoptosis of fibroblast-like synoviocytes Abstract Background Long non-coding RNA (lncRNA) growth arrest specific transcript 5 (GAS5) negatively regulates interleukin-18 (IL-18) in ovarian cancer, while IL-18 contributes to the development of rheumatoid arthritis (RA). Therefore, GAS5 may also participate in RA. Methods GAS5 and IL-18 in plasma of RA patients (n = 60) and healthy controls (n = 60) were measured by RT-qPCR and ELISA, respectively. Linear regression was performed to analyze the correlations between plasma levels of IL-18 and GAS5 in both RA patients and healthy controls. Results In the present study, we found that plasma GAS5 was downregulated, while IL-18 was upregulated in RA patients than in healthy controls. A significant and inverse correlation between GAS5 and IL-18 was found in RA patients but not in healthy controls. IL-18 treatment did not significantly alter the expression of GAS5 in fibroblast-like synoviocytes, while GAS5 overexpression led to the inhibited expression of IL-18. GAS5 overexpression also resulted in the promoted apoptosis of fibroblast-like synoviocytes. Conclusions Therefore, GAS5 overexpression may improve RA by downregulating IL-18 and inducing the apoptosis of fibroblast-like synoviocytes. Key points • The present study mainly showed that overexpression of GAS5 may assist the treatment of RA. • The mechanism of GAS5 for the treatment of RA involves the downregulating inflammatory IL-18 and mediating the apoptosis of fibroblast-like synoviocytes. • GAS5 and IL-8 were correlated in RA patients but not in healthy controls.
