A national, multicenter, retrospective study evaluating retention rate and efficacy of tocilizumab treatment in patients with active rheumatoid arthritis who had an inadequate response to csDMARDs and/or TNF inhibitors.

BACKGROUND: To describe the disease activity and retention rate in rheumatoid arthritis (RA) patients with inadequate response (IR) to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and/or tumor necrosis factor inhibitors (TNFis) who were prescribed tocilizumab (TCZ) as first-line or second-line biologic treatment in real-world setting. METHODS: Data gathered from patients' files was used in a multicenter and retrospective context. Retention rates and the Disease Activity Score in 28 joints with CRP (DAS28-CRP) were evaluated at time points. The relationship of drug efficacy with factors such as smoking, obesity, and previous use of TNFis was also examined. RESULTS: One hundred and twenty-four patients with a median (IQR) RA duration of 3.7 (7.4) years were included. Mean (SD) age was52.9 (12.9) and 75% of the patients were female. TCZ retention rates in the 6th and 12th months were 94.1% and 86.6%, respectively. In all patients, DAS28-CRP level decreased significantly from baseline to Months 3 and 6. There was an increase in patients with remission and/or low disease activity and a decrease in patients with high disease activity at Month 3 and Month 6 (p < 0.001 for both). Disease activity was similar between subgroups based on body mass index, smoking status, and previous use of TNFis at any time point. Regression analysis showed that absence of concomitant corticosteroid treatment independently was associated with remission/LDA achievement at Month 6 [OR = 0.31, 95% CI (0.14- 0.72), p = 0.006], and Month 12 [OR = 0.35, 95% CI (0.13-0.94), p = 0.037]. Overall, 25 mild adverse events were reported. DISCUSSION: TCZ was found to be effective and safe in RA patients with IR to csDMARDs and/or TNFis. The drug retention rate was considered satisfactory with more than half of the patients continuing TCZ treatment at Month 12.

Canakinumab is effective in patients with familial Mediterranean fever resistant and intolerant to the colchicine and/or anakinra treatment.

As an autosomal recessive autoinflammatory disease, treatment of Familial Mediterranean fever (FMF) has still gaps. Clinical studies are proving the safety and efficacy of colchicine in patients with FMF. However, there are very limited data on colchicine-resistant patients treated with canakinumab. This study presents the real-life experience of two rheumatology clinics choosing canakinumab in adult patients with FMF resistant to standard therapy. Treatment-resistant FMF patients with validated diagnoses enrolled from two rheumatology clinics. A special database was generated for the study and patients' demographic characteristics, FMF attack characteristics, adverse events seen during treatment, family history, MediterraneanFeVer (MEFV) mutations, and laboratory results recorded. Patients with missing dates were excluded from the analysis. PRAS score is used to assess the disease activity. A total of thirty colchicine and/or anakinra-resistant patients were enrolled to study. Twenty-one patients were female (70%) and the average disease duration was 21 years. The time from colchicine to anakinra was 4.27 years and the time to canakinumab was 1.52 years. Abdominal pain (100%), fever (93.3%), chest pain (56.7%) were the most prevailed findings. Morning stiffness, myalgia, low back pain, chest pain was the predominant musculoskeletal findings. Median colchicine dose was 2 mg/day (min-max 0.5-3 mg/day). The most common side effect during anakinra treatment, apart from treatment unresponsiveness, was injection site reactions. Before canakinumab treatment, the mean number of attacks was 8.3 in the 24 weeks, 4.33 in the third month of canakinumab treatment, and 1.56 at the last visit (p < 0.001). Also, the mean duration of attacks was 67.20 h before canakinumab treatment, this period decreased to 18.27 h after six months of canakinumab treatment (p < 0.001). Canakinumab is effective and tolerable to reduce attacks in resistant patients with FMF. Laboratory findings and clinical observation reveals that canakinumab can be another treatment option for colchicine and/or anakinra non-responders. Further studies with larger patients are required to validate recent findings with canakinumab.

Tofacitinib monotherapy and erectile dysfunction in rheumatoid arthritis: a pilot observational study.

We aimed to explore the effect of tofacitinib on erectile dysfunction (ED), as well as disease activity and health related quality of life in male patients with rheumatoid arthritis (RA). Forty eight male RA patients with ED were included. Demographic and clinical data at baseline and 6 month of treatment were recorded from patients' medical records. Disease activity was evaluated with the disease activity score on 28 joints (DAS28), quality of life with Health Assessment Questionnaire-Disability Index (HAQ-DI) and ED with International Index of Erectile Function-5 (IIEF-5). The patients were aged 45.58 [Formula: see text] 2.14 years with a disease duration of 79.33 [Formula: see text] 25.31 months. According to the IIEF-5, 17 (35.4%) patients had severe ED, 10 (20.8%) patients moderate ED, 10 (20.8%) patients mild to moderate ED and 11 (22.9%) patients mild ED. For the entire patient group, baseline median IIEF-5 score was significantly increased from 9.35 (5.30-19.40) to 9.90 (5.20-24.90), baseline median DAS28 was significantly decreased from 5.65 (4.80-6.70) to 5.00 (2.40-6.40), HAQ-DI from 1.70 (1.10-2.40) to 1.15 (0.40-2.20) at 6th month of treatment (all p value < 0.001). Also, quantitative change in IIEF-5 was significantly correlated with changes in DAS28 (r: - 0.735, p < 0.001) and HAQ-DI (r: - 0.700, p < 0.001). Tofacitinib monotherapy may improve ED severity and as well as disease activity and health related quality of life in male patients with RA complaining of ED.

Real-life data on tapering or discontinuation of canakinumab therapy in patients with familial Mediterranean fever.

This study aimed to investigate the disease characteristics of familial Mediterranean fever (FMF) patients undergoing dose optimisation and discontinuation of canakinumab therapy. A total of 61 patients diagnosed with FMF and using canakinumab for the resistant disease were enrolled on this retrospective study. Patients' characteristics, disease activity, treatment response, dose optimisation, dose intervals, attack-free periods, drug-free periods and side effects were noted. Dose intervals were extended in patients who achieved remission without being bound by any protocol at the discretion of the rheumatology physician who followed up with the patients in the outpatient clinic. The drug was discontinued in some patients whose dose intervals were 2 months or longer and remained in remission for 6 months or longer. A total of 57 patients (56% female, median age 32.4 years) were included. The mean attack frequency before canakinumab was 3.4/6 months, while it was 1.2 at the last post-treatment visit (p < 0.001). The median duration of canakinumab use was 46 months. After the first 6 months, the dosing interval was extended in 22 patients, and then treatment was discontinued in 12 of them who did not have an attack in the last 6 months. Three of the 12 patients whose treatment was discontinued started monthly treatment again after their attacks recurred. In the remaining ten patients, dose intervals were extended to 8-12 weeks after 6 months of monthly treatment. Nine patients are still being followed up without attacks and receive only colchicine therapy. Canakinumab is a safe and effective treatment, dose intervals may be extended, and follow-up without medication may be possible for eligible patients. However, there is a need for a consensus on dose optimisation or tapering.

Perspective of sarcoidosis in terms of rheumatology: a single-center rheumatology clinic experience.

Sarcoidosis may present with many rheumatological symptoms as well as mimic and/or may occur concomitantly with many other rheumatic diseases. We examined the demographic, clinical and laboratory characteristics of patients diagnosed with sarcoidosis in the rheumatology department. This study planned as retrospective cross-sectional study. Medical records of patients who applied to our rheumatology outpatient clinic due to complain of musculoskeletal problems and then diagnosed sarcoidosis were retrospectively investigated. Joint findings, extrapulmonary involvements, and coexisting rheumatic disease were evaluated. Fifty-six patients (41.21 ± 7.83 years, 75% female) were included. The duration of the disease was 49.61 ± 29.11 months, and the follow-up period was 26.66 ± 13.26 months. All patients had pulmonary system involvement. Arthralgia was present in 91.10% of 56 patients and arthritis in 89.29% of patients. Examining the subtypes of the arthritis findings, mono-arthritis was found in 31/50 (62%) patients, oligo-arthritis in 15/50 (30%) patients, and polyarthritis in 4/50 (8%) patients. A total of 11 (19.60%) patients were diagnosed with uveitis. Excision of the mediastinal LAP was performed in a total of 37 patients (66.1%) and became the most commonly employed method. Considering the treatment distribution of the patients under followed-up, it is seen that non-steroidal anti-inflammatory treatments were used in 15 (26.8%) patients, corticosteroids in a total of 40 (71.4%) patients, methotrexate in a total of 15 patients (26.8%), azathioprine in six (10.7%) patients, hydroxychloroquine in 14 (25%) patients, and infliximab in one (1.8%) patient. As sarcoidosis is a mimicking disease, a good differential diagnosis should be made to avoid misdiagnosis and in order not to be late in diagnosis and treatment. Physicians, especially rheumatologists, should remember sarcoidosis more frequently as the disease may overlap with other rheumatological diseases and may occur with many rheumatological manifestations.

Use of non-TNF biologics for the treatment of neuro-Behçet's disease: Literature review and 2 refractory cases of monoclonal anti-TNFs treated with tocilizumab.

Neurological complications of BD (neuro-Behçet's disease [NBD]) are life-threatening and disabling manifestations. Neurological involvement occurs in approximately 5% to 18% of patients with BD. Most patients with NBD respond well to glucocorticoids, cyclophosphamide, or anti-tumor necrosis factors (TNFs), but there are some resistant cases refractory to these drugs. This study aims to summarize the existing data on the management of NBD, with special focus on patients resistant to anti-TNFs. The study included a short review of early treatment steps. In addition to a literature review of treatment with non-TNF biologics, we present 2 NBD cases with neurological involvement that are resistant to standard high-dose steroid therapy and anti-TNF treatment. Both patients responded well to the tocilizumab therapy, and there was no serious adverse event.

Effects of the Disease Characteristics and the Treatment on Psychological Status in Patients with Rheumatoid Arthritis and Ankylosing Spondylitis.

INTRODUCTION: Various psychiatric disorders, especially depression and anxiety, are seen in 2/3 of the chronic rheumatic diseases with chronic pain. In this study, we aimed to define anxiety and depression rates in Rheumatoid Arthritis (RA) and Ankylosing Spondylitis (AS) patients (under treatment) with similar age and gender; to compare the obtained data with each other and healthy control group; and also we aimed to investigate the relationship between human leukocyte antigen B27(HLA-B27) in AS, Rheumatoid Factor (RF) and anti-cyclic citrullinated peptide antibodies (anti-CCP) in RA with anxiety and depression. METHOD: 46 patients with RA, 43 patients with AS and 29 healthy volunteers were evaluated with Beck Depression Inventory (BAI) and Beck Anxiety Inventory (BAI). Participants were also noted for their educational status, occupation status, family history of illness, duration of the disease and their current treatments. Then we compared the obtained data with the healthy control group. SPSS (IBM Corp. Released 2012. IBM SPSS Statistics for Windows, Version 21.p=0. Armonk, NY: IBM Corp.) was used for performing statistical analysis. RESULTS: There was no difference between the groups according to age, sex, duration of illness (p=0.104, p=0.767, p=0.377). A significant difference between groups in terms of BAI values were determined (p=0.018). In subgroup analyzes, the median BAI value of AS group was found to be higher than the control group (p=0.020). There were no differences in BAI values between AS and RA groups or between RA and the control groups (p>0.05, p>0.05 respectively). Also, there were no differences between the groups in terms of BDI values (p=0.055). CONCLUSIONS: Especially, chronic pain-related diseases are often associated with mental disorders, especially depression and anxiety. As a result, a multidisciplinary approach including psychiatric support should be used when planning treatment for these patients.
