The EULAR points to consider for use of antirheumatic drugs before pregnancy, and during pregnancy and lactation

A European League Against Rheumatism (EULAR) task force was established to define points to consider on use of antirheumatic drugs before pregnancy, and during pregnancy and lactation. Based on a systematic literature review and pregnancy exposure data from several registries, statements on the compatibility of antirheumatic drugs during pregnancy and lactation were developed. The level of agreement among experts in regard to statements and propositions of use in clinical practice was established by Delphi voting. The task force defined 4 overarching principles and 11 points to consider for use of antirheumatic drugs during pregnancy and lactation. Compatibility with pregnancy and lactation was found for antimalarials, sulfasalazine, azathioprine, ciclosporin, tacrolimus, colchicine, intravenous immunoglobulin and glucocorticoids. Methotrexate, mycophenolate mofetil and cyclophosphamide require discontinuation before conception due to proven teratogenicity. Insufficient documentation in regard to fetal safety implies the discontinuation of leflunomide, tofacitinib as well as abatacept, rituximab, belimumab, tocilizumab, ustekinumab and anakinra before a planned pregnancy. Among biologics tumour necrosis factor inhibitors are best studied and appear reasonably safe with first and second trimester use. Restrictions in use apply for the few proven teratogenic drugs and the large proportion of medications for which insufficient safety data for the fetus/child are available. Effective drug treatment of active inflammatory rheumatic disease is possible with reasonable safety for the fetus/child during pregnancy and lactation. The dissemination of the data to health professionals and patients as well as their implementation into clinical practice may help to improve the management of pregnant and lactating patients with rheumatic disease.

Safety and clinical outcomes of rituximab therapy in patients with different autoimmune diseases: experience from a national registry (GRAID)

IntroductionEvidence from a number of open-label, uncontrolled studies has suggested that rituximab may benefit patients with autoimmune diseases who are refractory to standard-of-care. The objective of this study was to evaluate the safety and clinical outcomes of rituximab in several standard-of-care-refractory autoimmune diseases (within rheumatology, nephrology, dermatology and neurology) other than rheumatoid arthritis or non-Hodgkins lymphoma in a real-life clinical setting.MethodsPatients who received rituximab having shown an inadequate response to standard-of-care had their safety and clinical outcomes data retrospectively analysed as part of the German Registry of Autoimmune Diseases. The main outcome measures were safety and clinical response, as judged at the discretion of the investigators.ResultsA total of 370 patients (299 patient-years) with various autoimmune diseases (23.0% with systemic lupus erythematosus, 15.7% antineutrophil cytoplasmic antibody-associated granulomatous vasculitides, 15.1% multiple sclerosis and 10.0% pemphigus) from 42 centres received a mean dose of 2,440 mg of rituximab over a median (range) of 194 (180 to 1,407) days. The overall rate of serious infections was 5.3 per 100 patient-years during rituximab therapy. Opportunistic infections were infrequent across the whole study population, and mostly occurred in patients with systemic lupus erythematosus. There were 11 deaths (3.0% of patients) after rituximab treatment (mean 11.6 months after first infusion, range 0.8 to 31.3 months), with most of the deaths caused by infections. Overall (n = 293), 13.3% of patients showed no response, 45.1% showed a partial response and 41.6% showed a complete response. Responses were also reflected by reduced use of glucocorticoids and various immunosuppressives during rituximab therapy and follow-up compared with before rituximab. Rituximab generally had a positive effect on patient well-being (physicians visual analogue scale; mean improvement from baseline of 12.1 mm).ConclusionsData from this registry indicate that rituximab is a commonly employed, well-tolerated therapy with potential beneficial effects in standard of care-refractory autoimmune diseases, and support the results from other open-label, uncontrolled studies.

EULAR recommendations for women's health and the management of family planning, assisted reproduction, pregnancy and menopause in patients with systemic lupus erythematosus and/or antiphospholipid syndrome.

Objectives Develop recommendations for womens health issues and family planning in systemic lupus erythematosus (SLE) and/or antiphospholipid syndrome (APS). Methods Systematic review of evidence followed by modified Delphi method to compile questions, elicit expert opinions and reach consensus. Results Family planning should be discussed as early as possible after diagnosis. Most women can have successful pregnancies and measures can be taken to reduce the risks of adverse maternal or fetal outcomes. Risk stratification includes disease activity, autoantibody profile, previous vascular and pregnancy morbidity, hypertension and the use of drugs (emphasis on benefits from hydroxychloroquine and antiplatelets/anticoagulants). Hormonal contraception and menopause replacement therapy can be used in patients with stable/inactive disease and low risk of thrombosis. Fertility preservation with gonadotropin-releasing hormone analogues should be considered prior to the use of alkylating agents. Assisted reproduction techniques can be safely used in patients with stable/inactive disease; patients with positive antiphospholipid antibodies/APS should receive anticoagulation and/or low-dose aspirin. Assessment of disease activity, renal function and serological markers is important for diagnosing disease flares and monitoring for obstetrical adverse outcomes. Fetal monitoring includes Doppler ultrasonography and fetal biometry, particularly in the third trimester, to screen for placental insufficiency and small for gestational age fetuses. Screening for gynaecological malignancies is similar to the general population, with increased vigilance for cervical premalignant lesions if exposed to immunosuppressive drugs. Human papillomavirus immunisation can be used in women with stable/inactive disease. Conclusions Recommendations for womens health issues in SLE and/or APS were developed using an evidence-based approach followed by expert consensus.

Improvement of coping abilities in patients with systemic lupus erythematosus: a prospective study

Objective: To evaluate a novel specific psychological intervention aimed at improving coping in patients with systemic lupus erythematosus (SLE). Methods: 34 community living SLE patients were recruited for the study. Intervention was undertaken in groups of up to eight patients and in two blocks over six months each. Eight patients were enrolled as a waiting list group. The 18 group sessions focused on information about the disease and specific problems of SLE patients, combining psychoeducative and psychotherapeutic elements. Psychological and medical evaluations were conducted at baseline and after three, six, and 12 months, using validated instruments. Results: The 34 SLE patients (91% female, mean age 42 years) improved significantly over a six month period on most of the psychological measuring instruments applied, such as depression, anxiety, and overall mental burden. The waiting list group showed no significant changes. Conclusions: Conceptualised psychoeducational support may produce a significant and sustained improvement in coping skills of SLE patients and hence in their quality of life.

Current state of evidence on ‘off-label’ therapeutic options for systemic lupus erythematosus, including biological immunosuppressive agents, in Germany, Austria and Switzerland – a consensus report

Systemic lupus erythematosus (SLE) can be a severe and potentially life-threatening disease that often represents a therapeutic challenge because of its heterogeneous organ manifestations. Only glucocorticoids, chloroquine and hydroxychloroquine, azathioprine, cyclophosphamide and very recently belimumab have been approved for SLE therapy in Germany, Austria and Switzerland. Dependence on glucocorticoids and resistance to the approved therapeutic agents, as well as substantial toxicity, are frequent. Therefore, treatment considerations will include ‘off-label’ use of medication approved for other indications. In this consensus approach, an effort has been undertaken to delineate the limits of the current evidence on therapeutic options for SLE organ disease, and to agree on common practice. This has been based on the best available evidence obtained by a rigorous literature review and the authors’ own experience with available drugs derived under very similar health care conditions. Preparation of this consensus document included an initial meeting to agree upon the core agenda, a systematic literature review with subsequent formulation of a consensus and determination of the evidence level followed by collecting the level of agreement from the panel members. In addition to overarching principles, the panel have focused on the treatment of major SLE organ manifestations (lupus nephritis, arthritis, lung disease, neuropsychiatric and haematological manifestations, antiphospholipid syndrome and serositis). This consensus report is intended to support clinicians involved in the care of patients with difficult courses of SLE not responding to standard therapies by providing up-to-date information on the best available evidence.

Low risk of renal flares and negative outcomes in women with lupus nephritis conceiving after switching from mycophenolate mofetil to azathioprine

OBJECTIVE MMF is teratogenic and needs to be replaced before pregnancy. This change may lead to flares. Our aim was to determine the risk of renal flares in women with LN who switched treatment from MMF to AZA before conception and to evaluate the outcome of their pregnancies. METHODS Medical records of women with LN counselled for pregnancy wish were reviewed. Women receiving treatment with either MMF or AZA (control group), with inactive lupus (SLEDAI ≤ 4) and quiescent LN (serum creatinine <1.5 mg/dl, inactive sediment and proteinuria <1 g/24 h for the preceding 6 months) were eligible for this study. RESULTS We identified 54 women [23 treated with MMF (group 1) and 31 treated with AZA (group 2)]. MMF dosage was tapered and subsequently transferred to AZA, which was maintained throughout pregnancy. Three (13%) patients (group 1) vs none (group 2) developed a renal flare 3-6 months after transitioning from MMF to AZA (P = 0.14) before pregnancy ensued. The only parameter with a significant difference in those with flare compared with those without was younger age (median 27 vs 30 years; P = 0.03). Risk for adverse outcome within 48 pregnancies (pre-eclampsia 9%, preterm delivery 20.5%) increased with every milligramme of prednisone dosage [odds ratio (OR) 2.03] and every single unit of SLEDAI score (OR 3.92). Renal flares occurred post-partum in two women. No patient developed worsening of renal function. CONCLUSION Replacing MMF with AZA in patients with quiescent LN for pregnancy planning rarely leads to renal flares. Pregnancy outcome was favourable.

Elevated levels of human beta-defensin 2 and human neutrophil peptides in systemic lupus erythematosus:

Objective: Defensins are immunomodulatory peptides and components of the innate immune response. They have been shown to be modulated in various disease states and in response to inflammatory stimuli. Recently, alpha-defensins have been implicated in the pathogenesis of autoimmune diseases. In order to explore whether these defensins may have a role in the pathogenesis of systemic lupus erythematosus (SLE), we sought to determine whether altered expression can be found in SLE patients. Material and Methods: Serum and EDTA-blood of 50 SLE patients who fulfilled the American College of Rheumatology (ACR) criteria (aged 41.4 ± 13.3 years) and 28 age- and sex-matched healthy controls were collected. Real-time polymerase chain reaction with gene-specific primers for human neutrophil peptides (HNPs), human beta-defensin 2 and 3 (hBD2, 3) in isolated polymorphonuclear cells and enzyme-linked immunosorbent assay (ELISA) in serum samples were performed. Results of SLE patients were compared with the control group and correlated to routine laboratory parameters, clinical data and Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). Results: SLE patients were predominantly female (90%) with a mean SLEDAI of 5.7 ± 6.1. In sera, patients displayed higher amounts of hBD2 and HNPs when compared with healthy controls. Furthermore, hBD2 correlated with levels of anti-dsDNA antibodies, erythrocyte count and the SLEDAI. Elevated values were observed in patients with myositis (n = 4). Serum HNPs on the other hand correlated with the neutrophil count and was elevated in patients with a rash (n = 7). Lupus patients suffering from transverse myelitis (n = 3) had raised serum-values of both HNPs and hBD2. While no mRNA of hBD2 or hBD3 was detected in polymorphonuclear cells, HNP mRNA was found in both healthy controls and patients without significant difference. Lupus nephritis and rash were associated with higher amounts of HNP mRNA, and the relative amount of copies correlated positively with the SLEDAI and negatively with C3 measurements. Conclusions: Serum levels of hBD2 and HNPs are elevated in SLE. The correlations of hBD2 and HNPs to established disease activity parameters and distinct clinical situations suggest that innate immune mechanisms are activated. Defensins may be involved in SLE pathogenesis.

Clinical outcomes and safety of rituximab treatment for patients with systemic lupus erythematosus (SLE) - results from a nationwide cohort in Germany (GRAID)

Objective The objective of this article is to evaluate the safety and clinical outcome of rituximab treatment in systemic lupus erythematosus (SLE) patients refractory to standard of care therapy in a real-life setting in Germany. Methods The GRAID registry included patients with different autoimmune diseases who were given off-label treatment with rituximab. Data on safety and clinical response were collected retrospectively. In SLE patients, clinical parameters included tender and swollen joint counts, fatigue, myalgia, general wellbeing, Raynaud’s and the SLEDAI index. Laboratory tests included dsDNA antibody titres, complement factors, hematologic parameters and proteinuria. Finally, the investigators rated their patients as non-, partial or complete responders based on clinical grounds. Results Data from 85 SLE patients were collected, 69 female and 16 male, with a mean disease duration of 9.8 years. The mean follow-up period was 9.6 ± 7.4 months, resulting in 66.8 patient years of observation. A complete response was reported in 37 patients (46.8%), partial response in 27 (34.2%), no response in 15 (19.0%). On average, major clinical as well as laboratory efficacy parameters improved substantially, with the SLEDAI decreasing significantly from 12.2 to 3.3 points. Concerning safety, one infusion reaction leading to discontinuation of treatment occurred. Infections were reported with a rate of 19.5 (including six severe infections) per 100 patient years. Conclusion With the restrictions of a retrospective data collection, the results of this study confirm data of other registries, which suggest a favourable benefit-risk ratio of rituximab in patients with treatment-refractory SLE.

Efficacy and Safety of Rituximab Treatment in Patients with Antineutrophil Cytoplasmic Antibody-associated Vasculitides: Results from a German Registry (GRAID)

Objective. Rituximab (RTX) therapy is a treatment option in patients with refractory antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). We investigated the tolerability and clinical efficacy of RTX in a cohort of patients with refractory AAV. Methods. Clinical and safety data of patients with AAV treated with RTX were retrospectively assessed from the data of a German national registry. Results. In total, 58 patients were included in this analysis (50/58 with granulomatosis with polyangiitis; 8/58 with microscopic polyangiitis who received at least 1 cycle, 17 patients who received 2 cycles, and 3 patients who received 3 cycles of RTX). Response was classified as complete and partial in 22 (40%) and in 29 cases (52.7%), respectively. Four patients (7.3%) were classified as nonresponders. Conclusion. RTX was well tolerated with good clinical efficacy in patients with refractory AAV.

Renal Outcome in Patients with Lupus Nephritis Using a Steroid-free Regimen of Monthly Intravenous Cyclophosphamide: A Prospective Observational Study

Objective. Intravenous cyclophosphamide (IV CYC) in combination with high doses of corticosteroids is considered the “gold standard” of therapy for lupus nephritis (LN). However, the optimal dose of corticosteroids needed has not been defined. We evaluated the efficacy of a monotherapy with IV CYC in patients with a first episode of LN (duration ≤ 6 months). Methods. Forty patients with LN received IV CYC (12 pulses). Prednisone alone was administered and dose-adjusted to control extrarenal manifestations. Response after 24 months was defined as normalization of creatinine level, inactive urinary sediment, and proteinuria ≤ 0.2 g/day [complete response (CR)] or ≤ 0.5 g/day [partial response (PR)]. Results. CR was achieved in 25 (62.5%) and PR in 8 (20%) patients. Mean starting dose of prednisone was 23.9 ± 23.8 mg/day. In a posthoc analysis, we separately analyzed patients initially treated with prednisone doses ≥ 20 mg/day (Group A, n = 19) or < 20 mg/day (Group B, n = 21). CR was achieved in 52.6% (Group A) versus 71.4% (Group B; p = 0.37); and PR in 26.3% versus 14.3%, respectively (p = 0.58). During longterm followup (10.4 ± 3.1 yrs), 37.8% experienced a renal flare. Thirty patients (81%) still have normal renal function. Renal outcome was irrespective of initial prednisone doses (p = 0.46, Pearson chi-square test of independence). Conclusion. Our rates of CR and PR and longterm outcomes were comparable with rates after treatment with a combination of IV CYC with high doses of corticosteroids. These data warrant randomized controlled trials evaluating different doses of corticosteroids in LN.
