ABSTRACT
Background/Aims Baricitinib is the most common Janus Kinase inhibitor (JAKi) used in the treatment of rheumatological conditions. Whilst randomised controlled trials have demonstrated the efficacy and safety profile of baricitinib, real-world data on the experience of JAKi use in clinical practice is lacking. The aim of this analysis was to evaluate baricitinib use in a real-world patient population in South London. Methods We looked at two rheumatology departments in South London (St George's Hospital;a tertiary teaching centre and Kingston Hospital;a district general hospital). All patients prescribed baricitinib between January 2017 to June 2022 were included. A retrospective assessment of electronic patient notes was performed to evaluate disease activity (determined by DAS-28 scores at baseline, 3-6 months and presently);adverse effects including side effects, rates of and reasons for discontinuation;and prescribing practice, including previous use of other biological disease modifying anti-rheumatic drugs (bDMARDs). Baseline data including age, gender, co-morbidities and rheumatological diagnoses were also included. Results 233 patients were included in this evaluation, with seropositive rheumatoid arthritis being the most common diagnosis (58%) and with a significant female population (87%). Baricitinib improved average DAS-28 scores from 5.75 (range 3.57-8.3) at baseline to 3.23 (range 0.28-7.49) at 3-6 months post-baricitinib, with the most recent DAS-28 score of 2.90 (range 0.56-6.77). Rates of adverse effects were low as shown in Table 1. Baricitinib was discontinued in 60/233 patients, with average duration to discontinuation of 9.5 months. The most common reasons for discontinuation were: ineffective disease control (28/60), recurrent bacterial infection (5/60), deranged liver function (3/60) and venous thromboembolism (2/60). Eight patients died whilst taking baricitinib. Where documented, the causes of death were Covid-19 (4/8) and malignancy (1/8). 110 out of 233 patients had received other bDMARDs before starting baricitinib. Documented reasons for baricitinib choice over tumour necrosis factor inhibitors (TNFi) included: previous lack of response to TNFi (89/233), contra-indication to TNFi (11/233) and preference of oral route (10/ 233). Conclusion Our real-world study of JAKi use shows that baricitinib is efficacious in the treatment of rheumatological conditions. Moreover, baricitinib is well tolerated, with low rates of adverse effects and subsequent discontinuation. (Table Presented).
ABSTRACT
Background/Aim: Long COVID-19 is one of the post-infection challenging issues. We aimed to assess the prevalence and characteristics of this syndrome in patients with autoimmune and rheumatic diseases (AIRDs) through a multicentre international e-surveys (The COVID-19 Vaccination in Autoimmune Diseases) COVAD study. Method(s): The COVAD group comprised of collaborators from 109 countries. An online survey platform was conducted in Jan-July 2022 to capture self-reported COVID-19 infection and vaccination data in patients with AIRDs and healthy controls (HCs). Long COVID-19 was defined as per WHO definitions as persistence of symptoms beyond 3 months of COVID-19 infection. Descriptive statistics and multivariable regression adjusted for age, gender, ethnicity, and disease modifying anti-rheumatic drugs (DMARDs) were employed. Result(s): Among the 7666 complete survey respondents, 1677 who had taken the survey >90 days of last COVID-19 infection were analyzed. Among them, a total of 8.1% (n = 136) had long COVID-19 syndrome and the median age was 46 (34-55) years, with Male: Female ratio of 1:6.3. The prevalence of long COVID-19 was significantly higher in patients with AIRDs compared to HCs (OR 2 [1.3-2.9], P < 0.001). Respondents with long COVID-19 had worse PROMIS 10a quality of life global physical and mental health score, as well as fatigue and pain VAS compared to those without post-COVID- 19 (all P < 0.001). Among patients with AIRDs, those with long COVID-19 reported to have higher flares of AIRDs following COVID-19 infection (OR 4.3, P < 0.01). On multivariable regression analysis, the characteristics of patients with long COVID-19 were female gender, Caucasian ethnicity and presence of comorbid insomnia. Presence of fatigue, muscle aches, dyspnoea and loss of taste during previous COVID-19 infection were the significant predictors of long COVID-19. Among patients with AIRDs, comorbidities (OR 2.0;95% CI: 1.08-3.6, P = 0.026), and advanced treatment (OR: 1.9;95% CI: 1.08-3.3, P = 0.024), or intensive care (OR: 3.8;95% CI: 1.01-14.4, P = 0.047) for severe COVID-19 were risk factors for long COVID-19. The use of rituximab, iv immunoglobulins (IVIG), mycophenolate mofetil and anti-TNF agents use also predicted long COVID-19. Conclusion(s): Patients with AIRDs are at higher risk of long-COVID- 19 syndrome. Associated comorbid conditions and advanced treatment or intensive care for severe COVID-19 confer a higher risk.
ABSTRACT
Background: Current research on COVID-19-related outcomes in patients with psoriasis, particularly regarding influence of treatments, are subject to lack of comparator group, selection bias, and insufficient statistical power.1 Accordingly, it remains uncertain whether immunomodulatory treatments for psoriasis enhance or decrease the risk of severe COVID-19-related outcomes, including hospitalization. Objective(s): To compare the risk of COVID-19-related hospitalization according to immunomodulator treatment type in patients with psoriasis Methods: Retrospective cohort study of the Explorys database in the United States between March 1st, 2020 and December 31st, 2020. Psoriasis diagnosis was defined by at least 2 ICD-9 or ICD-10 diagnosis codes prior to March 1st, 2020. Drug exposure was classified as biologic or traditional immunosuppressive (methotrexate, cyclosporine, apremilast) treatment based on prescription order in the 3 months preceding March 1st, 2020. Biologic treatments included TNFalpha, IL-12/IL-23, IL-17A, IL-23 and JAK inhibitors. The primary outcome was defined as hospital admission with diagnosis of COVID-19 or positive lab test occurring between admission and discharge date. Propensity score weighting was used to compare COVID-19-related hospitalization between treatment groups, adjusting for comorbidities and demographic characteristics. Result(s): A total of 51,606 psoriasis patients aged 18-88 were included. Crude cumulative incidence of COVID-19 hospitalization per 1,000 psoriasis patients was 3.4 in the biologic group (9/2,669), 9.5 in the traditional immunosuppressive group (15/1,585), and 3.9 in those receiving neither drug class (184/47,352). Incidence was 4.7 (6/1,282) and 14 (13/898) per 1,000 patients among those receiving TNF-alpha inhibitors and methotrexate, respectively. After propensity-score weighting, risk of COVID-19-related hospitalization for patients receiving any biologic was lower than that of patients receiving traditional immunosuppressives (RR 0.39, 95% CI 0.16, 0.92), and those receiving neither drug class (RR 0.66, 95% CI 0.32, 1.34). TNF-alpha inhibitor use was associated with lower risk of hospitalization relative to methotrexate use (adjusted RR 0.39, 95% CI 0.14, 1.06). Adjusted relative risk of hospitalization for methotrexate users relative to those receiving neither drug class was 2.78 (95% CI 1.47, 5.26). Conclusion(s): During the first wave of the pandemic in 2020, psoriasis patients using biologics were at lower risk of COVID-19-related hospitalization compared to those using traditional immunosuppressives, particularly methotrexate. Methotrexate use was associated with a substantial increase in risk of hospitalization relative to those who did not receive systemic treatments.
