Cancer complicating systemic lupus erythematosus--a dichotomy emerging from a nested case-control study

We determined whether any individual cancers are increased or decreased in a cohort of 595 patients with systemic lupus erythematosus (SLE) followed for up to 32 years at the University College London Hospitals Lupus Clinic, looking for any associated clinical or serological factors and the prognosis after cancer diagnosis

Effects of rituximab-based B-cell depletion therapy on skin manifestations of lupus erythematosus--report of 17 cases and review of the literature

Cutaneous manifestations occur frequently in systemic lupus erythematosus (SLE) and are pathognomonic in subacute-cutaneous lupus erythematosus (SCLE) and chronic cutaneous lupus erythematosus (CCLE). Although B-cell depletion therapy (BCDT) has demonstrated efficacy in SLE with visceral involvement, its usefulness for patients with predominant skin manifestations has not been fully established. In this single-centre, retrospective study 14 consecutive SLE, one CCLE and two SCLE patients with recalcitrant skin involvement were treated with 2 × rituximab 1 g, and 1 × cyclophosphamide 750 mg. Six months after BCDT, nine of 17 (53%) patients were in complete (CR) or partial remission (PR). Relapses occurred in 12 patients (71%) at a mean time of 10 ± 1.8 months after BCDT. A second cycle of BCDT achieved a more sustained remission in seven of nine patients (78%) lasting for a mean time of 18.4 ± 2.7 months. Minor adverse events were experienced by three patients. Mean follow-up was 30 months. Our own results and the literature review demonstrate that BCDT based on rituximab is well tolerated and may be effective for cutaneous lesions of lupus erythematosus. Randomized controlled trials are necessary to further evaluate the value of BCDT for this group of patients

A study of the influence of ethnicity on serology and clinical features in lupus

OBJECTIVE: The objective of this study was to review the links between ethnicity, serology and clinical expression in systemic lupus erythematosus (SLE) in a single cohort that was followed over a 36-year period. PATIENTS AND METHODS: Patients with SLE treated at the University College London Hospitals (UCLHs) between January 1978 and December 2013 formed the cohort. We assessed the demographic, clinical and serological data. Standard methods were used for laboratory testing. The Student t test and Mann-Whitney U test were used for the continuous variables; the Fisher's exact test was used for the categorical variables. RESULTS: We studied 624 SLE patients: There were 571 women (91.5%), with a mean age at diagnosis of 29.0 ± 6.5 years; and 53 men (8.5%), with a mean age at diagnosis of 29.4 ± 15.3 years. Ethnically, 369 of the patients were European, 100 were Afro-Caribbean, 77 were East Asian, 56 were South Asian and 21 were of mixed ethnicity. The East Asian patients developed the disease at a younger age than the other ethnic groups (p < 0.0001). The Afro-Caribbean patients were less frequently associated with the presence of rash and photosensitivity, and the non-European patients were more likely to have alopecia and renal involvement. The South Asian patients were significantly associated with musculoskeletal and neurological involvement, serositis, Sicca syndrome and hematological features. The Afro-Caribbean patients had the highest prevalence of anti-Smith, anti-RNP, anti-Ro and anti-La antibodies. Anti-IgG anticardiolipin (aCL) antibodies were significantly associated with the non-East Asian groups; and hypocomplementemia was common in the East Asians. Rash, alopecia, mouth ulcers, serositis, neurological, joint and renal involvement were significantly associated with the presence of anti-Smith and anti-RNP antibodies in the Afro-Caribbean group. We also observed an association of joint involvement and the presence of anti-Ro and anti-La antibodies in this group. CONCLUSIONS: The East Asian patients developed their SLE disease at a younger age than the other ethnic groups. Cutaneous involvement was more frequent in those who were not Afro-Caribbean. Serositis, joint and neurological involvement were more frequently diagnosed in the South Asian patients. Anti-ENA antibodies were frequently associated with the Afro-Caribbean patients

Rituximab - The first twenty years

It is now two decades since Rituximab was first used in the treatment of patients with systemic lupus erythematosus. There have been many challenges but in spite of failing to meet its primary endpoints in two clinical trials it is widely used for many aspects of lupus, its side-effects and the possibility that combining it with Benlysta may be of value. We also consider the proposal that it may provide a useful initial therapy. In this review, we consider the place of Rituximab in the treatment of lupus and anticipate how developments in fully-humanized anti-CD20 monoclonals may well extend the "therapeutic life" of B-cell depletion as a viable treatment option

"Mixed connective tissue disease": a condition in search of an identity

Mixed connective tissue disease was first described as a new autoimmune rheumatic disease in 1972 based on the claim of a distinct clinical picture associated with anti-RNP antibody positivity. Subsequently, this new entity has divided opinions in the rheumatology community. We have reviewed recent cohort studies with more than 100 patients, comparing the clinical and immunological features, treatment, prognosis and evolution to well-defined autoimmune rheumatic diseases. We also reviewed clinical features of undifferentiated autoimmune rheumatic diseases based on the most recent studies. After gathering and reviewing these data, we discuss whether the designation "mixed connective tissue disease" should be maintained

How I treat anticoagulant-refractory thrombotic antiphospholipid syndrome

The standard treatment of thrombotic antiphospholipid syndrome (APS) is lifelong oral anticoagulation with a vitamin K antagonist (VKA), generally warfarin. A minority of APS patients re-thrombose despite seemingly adequate anticoagulation. These patients are deemed anticoagulant-refractory. The management of anticoagulant-refractory APS is largely empirical and extrapolated from other clinically similar situations. Further options include increased VKA anticoagulation intensity or alternative antithrombotic strategies, including low-molecular-weight heparin, fondaparinux, the addition of antiplatelet therapy and consideration of vascular options. Anticoagulant-refractory thrombotic APS patients may have APS-associated thrombocytopenia, which necessitates balancing the risk of recurrent thrombosis versus bleeding, to achieve adequate anticoagulation. The multiple mechanisms involved in the generation of the thrombotic phenotype in APS suggest that anticoagulation alone may not control thrombosis. Thus, other modalities, including adjunctive treatment (hydroxychloroquine, statins and vitamin D) for APS-related thrombosis merit consideration, as well as immunomodulatory therapy and complement inhibition. APS patients may have coexistent systemic lupus erythematosus, which adds to the complexity of managing their thromboembolic disease. However, with attention to detail and judicious application of the limited data, it is possible to minimise the morbidity resulting from anticoagulant-refractory thrombotic APS. Multicentre studies are required to guide the sequence of interventions and their comparative efficacy in patients with anticoagulant-refractory thrombotic APS

Biologic therapies for systemic lupus erythematosus: where are we now?

PURPOSE OF REVIEW: Conventional approaches using hydroxychloroquine, corticosteroids and immunosuppressives have improved the prognosis for systemic lupus erythematosus (SLE) patients. Unfortunately, they have reached the limits of what they can achieve and patients still die prematurely and/or find their quality of life greatly impaired. Here, we discuss the problems of assessing activity in SLE, optimizing clinical trial design and more recent biologic approaches. RECENT FINDINGS: The success of B-cell depletion using Rituximab in open clinical studies, the approval of Belimumab (blocks the B-cell activating factor BAFF) and improvements in clinical trial design, gives cause for hope. Approaches including the use of fully humanized anti-CD20 and CD19 monoclonals, blocking interferons, inhibiting Bruton's tyrosine kinase (BTK), blocking the CD40 ligand (CD40L), utilizing an analogue of the FcɣRIIB and an IL12-23 blocker and targeting the JAK-STAT pathway have met end points in phase II and III trials. SUMMARY: For 20 years, we hoped that the successes of the biologic therapies in rheumatoid arthritis and psoriatic arthritis would be replicated in SLE but we have been generally disappointed. However, the encouraging recent results with monoclonals that block interferon and fully humanized anti-CD20 in particular, offer the prospect of a real revolution in the treatment of SLE

The use of anti-TNF-alpha therapies for patients with systemic lupus erythematosus. Where are we now?

INTRODUCTION: Systemic lupus erythematosus (SLE) is an autoimmune rheumatic disease characterized by multiple pathologies in which sustained inflammatory activity leads to progressive tissue destruction and organ damage. One of the main proinflammatory cytokines playing a key role in autoimmune diseases such as rheumatoid arthritis (RA) or SLE, is tumor necrosis factor (TNF) alpha. AREAS COVERED: The introduction of TNF-alpha inhibitors revolutionized the treatment of RA and other conditions including psoriatic arthritis and ankylosing spodylitis. We review here the efficacy and safety of TNF-alpha blockers in SLE focussing on why it has not been more widely used since TNF-alpha was reported to be increased in SLE patients and to correlate with disease activity. EXPERT OPINION: We summarize the reported SLE cases that have received TNF-alpha blockers and the main results to date. We reflect on whether there is a case to reconsider the use of TNF-alpha blockade in SLE

Very Delayed Lupus Nephritis: a Report of Three Cases and Literature Review

Lupus nephritis (LN) affects up to 50% of patients with Systemic Lupus Erythematosus (SLE) and is associated with a worse prognosis. LN usually develops within the first 5 years of the onset of the disease. We report three patients with very delayed LN (DLN) diagnosed after 15 or more years after SLE diagnosis. The three patients were non-Caucasian women with adolescent or adult-onset SLE. Each had antinuclear, anti-dsDNA and anti-Ro antibodies. Hydroxychloroquine was prescribed for each. Their disease courses were characterised by sporadic non-renal flares controlled by steroids and, in two cases, by one cycle of rituximab. Unexpectedly, they developed proteinuria, haematuria and lowering of estimated glomerular filtration rate with clinical signs of renal disease. LN was confirmed by renal biopsy. Reviewing them, each showed serological signs of increasing disease activity (rising levels of anti-dsDNA antibodies and fall in C3) that predated clinical or laboratory signs of LN by 1-3 years. Reviewing the literature, we found a lack of knowledge about DLN starting more than 15 years after SLE diagnosis. With the increasing life expectancy of patients with SLE it is likely that more cases of very DLN will emerge.info:eu-repo/semantics/publishedVersio
