The rate of preterm deliveries and intrauterine growth restriction (IUGR) seems to be increased, while the risk of miscarriages is controversial. Moreover, no study compared pregnancy outcomes in SSc with antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE). We performed a retrospective study to compare the pregnancy and disease outcomes of women with SSc with a cohort of age-matched women with systemic lupus erythematosus (SLE), antiphospholipid syndrome (APS), and healthy controls (HC). Methods A total of 154 pregnancies from SSc, SLE, APS patients, and HC were prospectively followed at the High-Risk Pregnancy Unit of our center from 2008 to 2019. The primary outcome was a composite endpoint of miscarriages, fetal deaths, intrauterine growth restriction (IUGR), preeclampsia, neonatal dea...

However, the differences in aPL prevalence decreased when an age-matched control group was included. The association of aPL with thrombotic events in COVID-19 is very heterogeneous. This could be influenced by the fact that most of the studies carried out were conducted on small populations enriched with elderly patients in which aPL was measured only at a single point and they were performed with non-standardized assays. The few studies that confirmed aPL in a second measurement showed that aPL levels hardly changed, with the exception of the lupus anticoagulant that commonly reduced. COVID-19 coagulopathy is an aPL-independent phenomenon closely associated with the onset of the disease. Thrombosis occurs later in patients with aPL presence, which is likely an additional prothrombotic factor. B2-glycoprotein deficiency (mainly aPL antigen caused both by low ...

The aim of this study was to assess this role in a real-life scenario. This retrospective, single-centre study included 56 patients with LN diagnosed from 1998 to 2019, with an initial kidney biopsy (KB1) at the onset of LN and a second kidney biopsy (KB2) after achieving renal remission. A total of 51 (91.1%) patients were women with a median age of 29.9 years [interquartile range (IQR) 23.4–40.6] at the time of LN diagnosis. KB2s were performed after 41.1 months (IQR 30.1–52.5) of KB1. At the time of KB2, complete renal response was achieved in 51 (91.1%) patients. The median activity index decreased from a baseline value of 6.5 (IQR 2.8–11) to 0 (IQR 0–2) (P < .001). The chronicity index worsened from 1 (IQR 0–2) to 2 (IQR 1–3) (P = .01). In patients with proliferative/mixed forms at KB2, the chronicity index median value increased to 3 (IQR 1.5–4), as well as interstitial fibrosis and tu...

In this article, we will review the drugs that have indication in patients with COVID-19, including corticosteroids, antimalarials, anti-TNF, anti-IL-1, anti-IL-6, baricitinib, intravenous immunoglobulins, and colchicine. The PubMed, Medline, and Cochrane Library databases were searched for English-language papers concerning COVID-19 treatment published between January 2020 and October 2020. Results were summarized as a narrative review due to large heterogeneity among studies...

Patients and methods. We analysed 56 BD patients (30 men; mean age, 34.4 ± 14.3 years) without any known thrombophilic factor, of which 17 had previously suffered from thrombosis (deep venous thrombosis in 14 and ischaemic stroke in 3), and 56 controls matched for age and sex. Additionally, we also evaluated 20 plasma samples with an international normalised ratio (INR) between 1.5 and 5.0 obtained from patients with atrial fibrillation but without a history of embolic events that were under treatment with acenocumarol. Thrombin generation was measured as ETP with a chromogenic assay in an automated analyser. Factor VIII, von Willebrand factor antigen, prothrombin fragment 1.2, D-dimer and plasmin-antiplasmin complexes were also measured. BD patients showed highe...

Our aim was to determine the prevalence of these antibodies in a wide spectrum of AID. We examined 923 serum samples representing 18 AID and compared them with 338 samples from healthy subjects. We used the BioPlex 2200-immunoassay (Bio-Rad, USA) to test samples for the presence of IgA and IgG directed at gliadin (AGA), tissue-transglutaminase (tTG), and Saccharomyces cerevisiae (ASCA). Prevalence of IgA AGA was significantly higher in antiphospholipid syndrome (APS) (7.1 %, P=0.012) and in pemphigus vulgaris (25%, P =0.008) patients, as compared with healthy controls. Presence of IgG-AGA was more common among Crohn's disease (20.5%, P = 0.023) and rheumatoid arthritis (6.5%, P=0.027) patients. IgG anti tTG were frequently observed in APS (6.1%, P=0.012), in giant cell arteritis (11.5%, P=0.013) and i...

Retrospective chart review from patients with BD treated with adalimumab in two specialized Spanish centres (Hospital Clínico San Cecilio, Granada and Hospital Clínic, Barcelona). From November 2006 to February 2011, 19 patients with BD were treated with adalimumab. The reason to initiate adalimumab was refractory disease in 17 (89.5%) patients and adverse events to CSA and infliximab in two (10.5%) patients, respectively. The main clinical manifestations leading to adalimumab administration were panuveitis in eight patients, severe bipolar aphthosis in eight, retinal vasculitis in three and severe folliculitis in three. Overall, adalimumab achieved clinical improvement in 17 of the 19 pati...

Retrospective and descriptive study of 496 patients recruited in sixteen centres on the frame of the Spanish Registry of Behçet Disease Project Group. Demographic and clinical data are presented in addition to treatments and their related adverse effects. Clinical features at disease onset and during follow-up were compared according to the sex of the patients. On the whole series, female to male ratio was 1.2:1.0. Mean age at disease onset was 28.7±12.6 years (range 17-73). Oral ulcers were the most frequent initial manifestation presented in 52.0% of patients. During follow-up, eye inflammatory disease was recorded in 45.1% of patients; thrombosis in 19.7% and central nervous system involvement in 13.5%. Men had higher prevalence of ocular involvement and venous thro...

We determined the serum concentration of interferon-γ (IFN-γ), interleukin-1β (IL-1β), IL-12p70, IL-17A, tumor necrosis factor-α (TNF-α), and hsCRP in 13 patients with active uveitis associated to BD, 24 inactive BD patients, and 20 controls. In a subgroup of 10 active patients, a second serum sample was obtained when the disease was inactive. Cytokine profiles and hsCRP levels were correlated with disease activity, severity, complications, and visual outcome. Levels of IFN-γ and TNF-α were significantly increased in patients with active uveitis associated to BD compared to controls (P < 0.05). IFN-γ, TNF-α, and hsCRP were significantly higher during active uveitis associated to BD compared to inactive disease (P…

During the 14th International Congress on Antiphospholipid Antibodies (aPL), a Task Force with internationally-known experts was created to carry out a critical appraisal of the literature available regarding the association of aPL with obstetric manifestations present in actual classification criteria (recurrent early miscarriage, fetal death, preeclampsia and placental insufficiency) and the quality of the evidence that treatment(s) provide benefit in terms of avoiding recurrent adverse obstetric outcomes. The association of infertility with aPL and the effectiveness of the treatment of patients with infertility and positive aPL was also investigated. This report presents current knowledge and limitations of published studies regarding pregnancy morbidity, infertility and aPL, identifying areas that need better investigative efforts and proposing how critical flaws could be avoided in future studies, as suggested by participants of the Task Force. Except for fetal death, there are limitations in the quality of the data supporting the association of aPL with obstetric complications included in the current APS classification criteria. Recommended treatments for all pregnancy morbidity associated to APS also lack well-designed studies to confirm its efficacy. APL does not seem to be associated with infertility and treatment does not improve the outcomes in infertile patients with aPL. In another section of the Task Force, Dr. Jane Salmon reviewed complement-mediated inflammation in reproductive failure in APS, considering new therapeutic targets to obstetric APS (Ob APS).
