Safety and Effectiveness of Biologic Disease-Modifying Antirheumatic Drugs in Older Patients with Rheumatoid Arthritis: A Prospective Cohort Study

Influences of advanced age in rheumatoid arthritis: A multicentre ultrasonography cohort study

OBJECTIVES

We aimed to evaluate the effects of age on clinical characteristics and outcomes in biologic or targeted synthetic disease-modifying antirheumatic drug (b/tsDMARD)-naïve patients with rheumatoid arthritis (RA).

METHODS

We analysed the cases of 234 Japanese b/tsDMARD-naïve RA patients who underwent b/tsDMARD treatment in a multicentre ultrasound prospective observational cohort. We compared the clinical characteristics at baseline and outcomes at 12 months between those aged ≥60 years and those <60 years.

RESULTS

Compared to the <60-year-old group (n = 78), the ≥60-year-old group (n = 156) had higher inflammatory marker values and ultrasound combined scores, especially wrist joints, at baseline. Age at baseline positively correlated significantly with the ultrasound scores at baseline; however, age was not a significant variable by the multiple regression analysis. The patients treated with different MOAs in the ≥60-year-old group had comparable outcomes and multiple regression analysis revealed that mechanism of action (MOA) was not a significant contributor to the Clinical Disease Activity Index at 12 months.

CONCLUSIONS

RA patients with advanced age demonstrated distinctive clinical characteristics. The MOAs were not associated with clinical outcomes and ultrasound outcomes in RA patients with advanced age.

Personalized medicine in rheumatoid arthritis: Combining biomarkers and patient preferences to guide therapeutic decisions

The last few decades have seen major therapeutic advancements in rheumatoid arthritis (RA) therapeutics. New disease-modifying antirheumatic drugs (DMARDs) have continued to emerge, creating more choices for people. However, no therapeutic works for all patients. Each has its own inherent benefits, risks, costs, dosing, and monitoring considerations. In parallel, there has been a focus on personalized medicine initiatives that tailor therapeutic decisions to patients based on their unique characteristics or biomarkers. Personalized effect estimates require an understanding of a patient's baseline probability of response to treatment and data on the comparative effectiveness of the available treatments. However, even if accurate risk prediction models are available, trade-offs often still need to be made between treatments. In this paper, we review the history of RA therapeutics and progress that has been made toward personalized risk predictive models for DMARDs, outlining where knowledge gaps still exist. We further review why patient preferences play a key role in a holistic view of personalized medicine and how this links with shared decision-making. We argue that a "preference misdiagnosis" may be equally important as a medical misdiagnosis but is often overlooked.

Persistence and Safety of Golimumab in Elderly Patients with Rheumatoid Arthritis and Renal Dysfunction in a Real-World Setting

BACKGROUND

The efficacy and safety of golimumab in elderly patients with renal dysfunction are not well evaluated due to the exclusion criteria of clinical trials.

OBJECTIVE

To assess the persistence and safety of golimumab in elderly rheumatoid arthritis patients with renal dysfunction.

PATIENTS AND METHODS

In this retrospective observational study, we used Japan's nationwide electronic medical records and claims database to identify patients aged 65 years and older who were newly prescribed golimumab for rheumatoid arthritis between July 2011 and June 2018. Patients were divided into three groups according to estimated glomerular filtration rate (eGFR; high, ≥ 90; moderate, ≥ 60, < 90; low, ≥ 30, < 60), and the persistence of golimumab and adverse events were compared between the groups.

RESULTS

A total of 423 patients met the eligibility criteria. At 6 months, the persistence rates of golimumab were 62.4%, 63.7% and 67.0% in the high, moderate and low eGFR groups, respectively. In Cox proportional hazards regression analysis, baseline eGFR was not associated with golimumab persistence or adverse events, but concomitant methotrexate and low baseline C-reactive protein (CRP) were associated with longer golimumab persistence.

CONCLUSION

Reduced renal function was not associated with continuation of golimumab or incidence of adverse events, suggesting that the persistence of golimumab therapy in patients with rheumatoid arthritis is independent of the baseline level of renal function. On the other hand, concomitant use of methotrexate and low baseline CRP levels were suggested as factors that may affect the persistence of golimumab treatment.

Do medical treatment choices affect the health of chronic patients in middle and old age in China?-Evidence from CHARLS 2018

Different medical treatment choices may affect the health of patients with chronic diseases. This study aims to assess the relationship between treatment choices, including the use of traditional Chinese medicine (TCM), and the health levels of middle-aged and elderly patients with six chronic diseases. The sample data comes from China Health and Retirement Longitudinal Study (CHARLS 2018). Basic conditions, medical choices and health status of patients are incorporated. The ordered Logit and Logit regression models are used to analyze and compare the effects of six chronic disease patients’ medical options on their self-rated health (SRH) and depression. The overall average score of SRH is the highest in patients with heart disease (the worst in SRH), which is 3.433. Arthritis patients have the highest overall depression average score (depression) at 0.444. Under the premise of controlling a variety of socio-demographic factors, compared with the non-treatment group, taking TCM has a significant positive effect on SRH of patients with five diseases except hypertension. Both taking western medicine (WM) and taking integrated Chinese and Western medicine (IM) have a significant positive effect on SRH scores of patients with six chronic diseases in middle and old age. Taking TCM has effect on depression of patients with heart or stomach diseases, and taking WM and IM affects depression of middle-aged and elderly chronic patients except diabetes. Taking IM has a greater effect on SRH and depression of chronically ill patients, followed by taking WM, and the effect of taking TCM is relatively small, which is related to the development stage of the disease. Therefore, in the future, the control and treatment of chronic diseases in the middle and late stages can be discussed from the perspective of integrated traditional Chinese and western medicine, but attention should be paid to drug interactions. In order to improve the treatment rate and health level of patients with chronic diseases, their economic burden should be reduced, and they should be guided to choose more reasonable treatment methods.

Assessment of physical function, quality of life, and medication adherence in elderly patients with rheumatic diseases

Background

The proportion of older people in the total population has increased in Turkey as well as worldwide. As life expectancy rises, the increasing prevalence of rheumatic diseases poses major problems in the elderly. Comorbid diseases and the aging-induced changes in the endogenous immune response and the pharmacokinetic properties of therapeutic agents may complicate the decision to use a particular drug and result in a different clinical picture and treatment response. We, therefore, aimed to investigate the characteristics of chronic inflammatory diseases, their impact on physical function and quality of life, the prevalence of comorbid diseases that may complicate treatment planning, and treatment adherence in patients aged 65 years or older.

Results

One hundred seventy-four patients were included and divided into two age groups: 18–64 years (group 1, n = 85) and 65 years or older (group 2, n = 89). The mean age of all recruited patients was 57.55 ± 16.98 years. Of 174, 99 (56.9%) were female and 75 (43.1%) were male. The mean duration of rheumatic disease was 7 ± 4.8 years and age at onset was 51.46 ± 14.78 years. Gender distribution differed significantly by age group (P = 0.024). The percentage of females in group 1 was 48.2% and 65.2% in group 2. The occupational status also differed significantly by age group (P < 0.001). 48.2% of group 1 were employed and 57.3% of group 2 were housewives. Marital status varied significantly by age (P < 0.001). The percentage of married was 74.1% in group 1 and the percentage of separated/divorced/widowed in group 2 was 28.1%. There was no difference between groups 1 and 2 in terms of place of residence (P = 0.459). The prevalence of comorbid diseases and the rate of use of medications for comorbid diseases (non-rheumatic treatments) were higher in elderly patients. The rate of use of disease-modifying anti-rheumatic drugs (DMARDs) was 30.3% and biological agents 61.8% in the elderly group (≥ 65 years) (group 2) (P < 0.001). There were positive correlations between, Health Assessment Questionnaire (HAQ), Bath Ankylosing Spondylitis Functional Index (BASFI) and Nottingham Health Profile (NHP) domains in both groups. There was also a significant negative correlation between Medication Adherence Rating Scale (MARS) and all dimensions.

Conclusions

Elderly and younger patients with rheumatic diseases have different demographic and clinical characteristics. Physical function and quality of life are more affected by rheumatic diseases and treatment adherence is poorer in the elderly. Our study found a positive correlation between physical function and quality of life in both age groups. The treatment adherence rating scale showed a negative correlation with physical function and quality of life scores, with individuals with poor treatment adherence having worse physical function and quality of life.

Natural and iatrogenic ocular manifestations of rheumatoid arthritis: a systematic review

Purpose

To provide an overview of the ocular features of rheumatoid arthritis (RA) and of the ophthalmic adverse drug reactions (ADRs) that may be associated with the administration of antirheumatic drugs.

Methods

A systematic literature search was performed using the PubMed, MEDLINE, and EMBASE databases. In addition, a cohort of 489 RA patients who attended the Authors’ departments were examined.

Results

Keratoconjunctivitis sicca, episcleritis, scleritis, peripheral ulcerative keratitis (PUK), and anterior uveitis were diagnosed in 29%, 6%, 5%, 2%, and 10%, respectively, of the mentioned cohort. Ocular ADRs to non-steroidal anti-inflammatory drugs are rarely reported and include subconjunctival hemorrhages and hemorrhagic retinopathy. In patients taking indomethacin, whorl-like corneal deposits and pigmentary retinopathy have been observed. Glucocorticoids are frequently responsible for posterior subcapsular cataracts and open-angle glaucoma. Methotrexate, the prototype of disease-modifying antirheumatic drugs (DMARDs), has been associated with the onset of ischemic optic neuropathy, retinal cotton-wool spots, and orbital non-Hodgkin’s lymphoma. Mild cystoid macular edema and punctate keratitis in patients treated with leflunomide have been occasionally reported. The most frequently occurring ADR of hydroxychloroquine is vortex keratopathy, which may progress to “bull’s eye” maculopathy. Patients taking tofacitinib, a synthetic DMARD, more frequently suffer herpes zoster virus (HZV) reactivation, including ophthalmic HZ. Tumor necrosis factor inhibitors have been associated with the paradoxical onset or recurrence of uveitis or sarcoidosis, as well as optic neuritis, demyelinating optic neuropathy, chiasmopathy, and oculomotor palsy. Recurrent episodes of PUK, multiple cotton-wool spots, and retinal hemorrhages have occasionally been reported in patients given tocilizumab, that may also be associated with HZV reactivation, possibly involving the eye. Finally, rituximab, an anti-CD20 monoclonal antibody, has rarely been associated with necrotizing scleritis, macular edema, and visual impairment.

Conclusion

The level of evidence for most of the drug reactions described herein is restricted to the “likely” or “possible” rather than to the “certain” category. However, the lack of biomarkers indicative of the potential risk of ocular ADRs hinders their prevention and emphasizes the need for an accurate risk vs. benefit assessment of these therapies for each patient.

Impact of age on the efficacy and safety of peficitinib (ASP015K) for the treatment of rheumatoid arthritis

OBJECTIVES

To evaluate peficitinib efficacy and safety in Asian patients with rheumatoid arthritis (RA), stratified by age (≥20-<50, ≥50-<65, and ≥65 years).

METHODS

Efficacy data from two Phase 3 studies were analysed. Safety data from one Phase 2, two Phase 3, and one open-label extension study were pooled. Incidence rates per 100 patient-years of adverse events of special interest were calculated, and Cox proportional hazard analysis was conducted.

RESULTS

1052 patients received peficitinib for 2 years (median). Peficitinib demonstrated efficacy improvements versus placebo across all age categories. Incidence rates (95% confidence interval) per 100 patient-years for ≥20-<50, ≥50-<65, and ≥65 years were 0.8 (0.4, 1.9), 2.6 (1.8, 3.7), and 4.7 (3.1, 7.0) for serious infections and 3.7 (2.5, 5.4), 6.4 (5.0, 8.2), and 11.2 (8.5, 14.7) for herpes zoster-related disease, respectively. Twenty patients reported malignancies in pooled Phase 2/3 studies. Incidences of serious infections and herpes zoster-related disease increased significantly with age, but there was no association with baseline estimated glomerular filtration rate.

CONCLUSIONS

Peficitinib was efficacious in adult Asian RA patients of all ages. Age, but not estimated glomerular filtration rate, was associated with serious infections and herpes zoster-related disease, demonstrating the importance of an appropriate RA treatment strategy in older patients.
