Sexual dysfunction in male patients treated with methorexate for arthritis: Analysis of the IIEF5 questionnaire and hormonal status.

OBJECTIVE: The aim of this study is to evaluate the impact of methotrexate (MTX) on erectile function in male patients through the International Index of Erectile Function (IIEF5) questionnaire and hormonal dosage. METHODS: Male patients affected by inflammatory arthritis (rheumatoid arthritis [RA] or psoriatic arthritis [PsA]) with good disease control and treated with chronic MTX were enrolled. Age-matched patients affected by chronic arthritis not treated with MTX were enrolled as controls. Each patient had a complete sexual hormone evaluation. IIEF5 questionnaire was administered to each patient. RESULTS: One hundred and nine patients were included, 77 in the MTX group and 32 as controls. The median weekly MTX dose was 10mg (IQR 7.5) with a median MTX duration therapy of 8 years (IQR 17). The total IIEF5 score was lower in patients MTX exposed compared to the control group without a significant result. The total IIEF5 score of patients treated with MTX≥5 years was statistically significantly lower when compared to those non-MTX exposed patients (17 [IQR 15] versus 20 [IQR 7.7]; P=0.04) and compared to those treated for<5 years (17 [IQR 15] versus 20 [IQR 7]; P=0.01). A negative correlation was identified between the total IIEF5 score and MTX time exposure (r=-0.20 CI [-0.38 to -0.04]; P=0.039). MTX exposure was still associated with a lower IIEF5 score when adjusted for age (ß Estimate=-2.63; CI [-5.13 to -0.13]; P=0.039). Hormonal dosage was similar in both groups for all hormones evaluated. CONCLUSION: MTX exposure was associated with a lower IIEF5 score in male patients adjusted for age. The preliminary results need to be confirmed in larger prospective studies.

Should We Use bDMARDs as an Induction Therapy in Early and Severe Rheumatoid Arthritis? Results at 5 years from the ERA UCLouvain Brussels Cohort.

INTRODUCTION: This study sought to analyze the benefit of an early induction therapy with a biological disease-modifying anti-rheumatic drugs (bDMARD) during the first year of treatment with a 5-year follow-up in early rheumatoid arthritis (ERA). METHODS: We included ERA patients from the UCLouvain Brussels cohort who met the American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) 2010 classification criteria and were naïve to DMARDs. ERA patients were divided into two groups according to whether they received an induction bDMARD therapy or a standard therapy with methotrexate (MTX). Clinical response after the induction treatment at 6 and 12 months followed by a MTX maintenance therapy at 36 and 60 months was evaluated. RESULTS: Data from 470 ERA patients were collected, 189 received a bDMARD and 281 initiated MTX alone. In the bDMARD group, disease activity and HAQ were higher at baseline. A total of 391 patients were followed up to 5 years. We then divided each group into two subgroups according to the last treatment they received at 5 years: bDMARD > MTX (n = 95), bDMARD > bDMARD (n = 59); MTX > MTX (n = 134), MTX > bDMARD (n = 103). During the induction, we observed a clinical response with a large number of patients achieving DAS28-CRP remission. According to a treat-to-target (T2T) approach, remission rate was stable on MTX monotherapy or rescued by the addition or prolongation of a bDMARD. Interestingly, bDMARD followed by a MTX maintenance therapy experienced a stable and sustained DAS28-CRP remission rate in 53% of the ERA patients at year 5. CONCLUSIONS: Long-term remission is an achievable goal in ERA. Our results suggest that a bDMARD induction therapy followed by MTX maintenance therapy could be an interesting option.

Anti-TNF Induced Sarcoidosis-Like Disease in Rheumatoid Arthritis Patients: Review Cases from the RA UCLouvain Brussels Cohort.

INTRODUCTION: Drug-induced sarcoidosis-like disease is a rare side effect of anti-tumor necrosis factor (anti-TNF) agents in rheumatoid arthritis (RA) patients. The most commonly involved organs in such condition are the lungs, skin, and lymph nodes. The aim of this study is to report the number of cases and the clinical manifestations of sarcoidosis induced by anti-TNF in our RA UCLouvain Brussels cohort. METHODS: All case records of RA patients ever treated with a TNF inhibitor and presenting anti-TNF induced sarcoidosis in our rheumatology centers from 2000 to 2021 were retrospectively reviewed. RESULTS: Our RA UCLouvain Brussels cohort includes 2492 patients. Among them, 697 patients have been or are exposed to a TNF inhibitor. Only four patients with sarcoidosis induced by anti-TNF were identified and reviewed. Patient 1 was classified as incomplete Heerfordt syndrome. Patient 2 was a case of sarcoid-like granulomatosis manifesting as life-threatening hypercalcemia, acute kidney injury and atypical parenchymal pneumopathy. Patients 3 and 4 developed pulmonary sarcoidosis with hilar adenopathies. The TNF inhibitor was etanercept for the first three patients and infliximab for the last one. The time occurrence of sarcoidosis was highly variable after anti-TNF exposure. All patients recovered after glucocorticoid treatment and the discontinuation of the anti-TNF agent. CONCLUSIONS: This case highlights this rare paradoxical side effect and the variability of the clinical presentation. Further studies should analyze the immunopathology of such conditions.

Should we use glucocorticoids in early rheumatoid arthritis? Results at 5 years from the early RA UCLouvain Brussels cohort.

OBJECTIVES: To evaluate the proportion of patients with early RA (ERA) who had or had not initiated glucocorticoids, to analyse the baseline characteristics, and to assess the clinical benefit and side effects of glucocorticoids during 5 years of follow-up. METHODS: We included patients with ERA from the UCLouvain Brussels cohort who met the ACR/EULAR 2010 classification criteria and were naïve to conventional DMARDs (cDMARDs). We retrospectively collected patient characteristics prior to the introduction of cDMARDs with or without glucocorticoids. Efficiency and serious adverse events were analysed at 6, 12, 36 and 60 months. RESULTS: Data from 474 eligible ERA patients were collected; 180 patients initiated glucocorticoids compared with 294 who did not. At baseline, the increased CRP was the main factor that favoured the initiation of glucocorticoids followed by smoking, absence of ACPA, prescription of MTX as a monotherapy and age. Five years' follow-up of DAS28-CRP, HAQ or visual analog score (VAS) pain values did not differ between the two groups. We also analysed a subgroup of 139 patients who received >1 g of prednisolone during the 5-year period. We confirmed the same baseline differences and observed in addition more men and higher DAS-28CRP values. During the 5 years' follow-up, DAS-28CRP, VAS pain and HAQ remained significantly higher in this subgroup. More severe infections were also reported. CONCLUSION: In our ERA cohort, the initiation of glucocorticoid treatment did not bring additional benefit for the short- and long-term control of the disease. Glucocorticoid was more prescribed in seronegative RA patients with a higher level of inflammation.

Tapering of biological antirheumatic drugs in rheumatoid arthritis patients is achievable and cost-effective in daily clinical practice: data from the Brussels UCLouvain RA Cohort.

BACKGROUND/PURPOSE: Studies have demonstrated that rheumatoid arthritis (RA) patients who achieve low disease activity or remission are able to taper biological disease-modifying antirheumatic drugs (bDMARDs). The aim of this study was to evaluate the proportion of patients in whom bDMARDs can be tapered in daily practice and to analyse the characteristics of these patients. Other objectives were to analyse which bDMARDs are more suitable for dose reduction and the cost savings. RESULTS: Data from 332 eligible RA patients from our Brussels UCLouvain cohort were retrospectively analysed; 140 patients (42.1%) received a tapered regimen, and 192 received stable doses of bDMARDs. The age at diagnosis (43.1 vs 38.7 years, p = 0.04), health assessment questionnaire (HAQ) score (1.3 vs 1.5, p = 0.048), RF positivity rate (83.3 vs 72.9%, p = 0.04) and disease duration at the time of bDMARD introduction (9.7 vs 12.1 years, p = 0.034) were significantly different between the reduced-dose and stable-dose groups. Interestingly, relatively more patients receiving a tapered dose were treated with a combination of bDMARDs and methotrexate (MTX) (86.7% vs 73.8%, p = 0.005). In our cohort, anti-TNF agents were the most commonly prescribed medications (68%). Only 15 patients experienced a flare during follow-up. Adalimumab, etanercept and rituximab were the most common bDMARDs in the reduced-dose group and were associated with the most important reductions in annual cost. CONCLUSION: In daily practice, tapering bDMARDs in RA patients who have achieved low disease activity or remission is an achievable goal in a large proportion of patients, thereby reducing potential side effects and annual drug-associated costs. The combination of bDMARDs with MTX could improve the success of dose reduction attempts. TRIAL REGISTRATION: This retrospective non-interventional study was retrospectively registered with local ethics approval.
