COVID-19 vaccine safety during pregnancy and breastfeeding in women with autoimmune diseases: results from the COVAD study.

OBJECTIVES: We investigated COVID-19 vaccine safety in pregnant and breastfeeding women with autoimmune diseases (AID) in the COVID-19 Vaccination in Autoimmune Diseases (COVAD) study. METHODS: Delayed-onset (>7 days) vaccine-related adverse events (AE), disease flares (DF), and AID-related treatment modifications were analyzed upon diagnosis of AID versus healthy controls (HC) and the pregnancy/breastfeeding status at the time of at least one dose of vaccine. RESULTS: Among the 9201 participants to the self-administered online survey, 6787 (73.8%) were women. Forty pregnant and 52 breastfeeding patients with AID were identified, of whom the majority had received at least one dose of COVID-19 vaccine (100% and 96.2%, respectively). AE were reported significantly more frequently in pregnant than in non-pregnant patients (overall AE 45% vs 26%, p= 0.01; minor AE 40% vs 25.9%, p= 0.03; major AE 17.5% vs 4.6%, p< 0.01), but no difference was found in comparison with pregnant HC. No difference was observed between breastfeeding patients and HC with respect to AE. Post-vaccination DF were reported by 17.5% of pregnant and 20% of breastfeeding patients, and by 18.3% of age- and disease-matched non-pregnant and non-breastfeeding patients (n = 262). All pregnant/breastfeeding patients who experienced a DF were managed with glucocorticoids; 28.6% and 20% of them required initiation or change in immunosuppressants, respectively. CONCLUSION: This study provides reassuring insights into the safety of COVID-19 vaccines administered to women with AID during the gestational and post-partum periods, helping overcome hesitant attitudes, as the benefits for the mother and the fetus by passive immunization appear to outweigh potential risks.

EULAR recommendations for cardiovascular risk management in rheumatic and musculoskeletal diseases, including systemic lupus erythematosus and antiphospholipid syndrome.

OBJECTIVE: To develop recommendations for cardiovascular risk (CVR) management in gout, vasculitis, systemic sclerosis (SSc), myositis, mixed connective tissue disease (MCTD), Sjögren's syndrome (SS), systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS). METHODS: Following European League against Rheumatism (EULAR) standardised procedures, a multidisciplinary task force formulated recommendations for CVR prediction and management based on systematic literature reviews and expert opinion. RESULTS: Four overarching principles emphasising the need of regular screening and management of modifiable CVR factors and patient education were endorsed. Nineteen recommendations (eleven for gout, vasculitis, SSc, MCTD, myositis, SS; eight for SLE, APS) were developed covering three topics: (1) CVR prediction tools; (2) interventions on traditional CVR factors and (3) interventions on disease-related CVR factors. Several statements relied on expert opinion because high-quality evidence was lacking. Use of generic CVR prediction tools is recommended due to lack of validated rheumatic diseases-specific tools. Diuretics should be avoided in gout and beta-blockers in SSc, and a blood pressure target <130/80 mm Hg should be considered in SLE. Lipid management should follow general population guidelines, and antiplatelet use in SLE, APS and large-vessel vasculitis should follow prior EULAR recommendations. A serum uric acid level <0.36 mmol/L (<6 mg/dL) in gout, and disease activity control and glucocorticoid dose minimisation in SLE and vasculitis, are recommended. Hydroxychloroquine is recommended in SLE because it may also reduce CVR, while no particular immunosuppressive treatment in SLE or urate-lowering therapy in gout has been associated with CVR lowering. CONCLUSION: These recommendations can guide clinical practice and future research for improving CVR management in rheumatic and musculoskeletal diseases.

International Delphi consensus guidelines for follow-up after prophylactic total gastrectomy: the Life after Prophylactic Total Gastrectomy (LAP-TG) study.

BACKGROUND: Prophylactic total gastrectomy (PTG) remains the only means of preventing gastric cancer for people with genetic mutations predisposing to Hereditary Diffuse Gastric Cancer (HDGC), mainly in the CDH1 gene. The small but growing cohort of people undergoing PTG at a young age are expected to have a life-expectancy close to the general population, however, knowledge of the long-term effects of, and monitoring requirements after, PTG is limited. This study aims to define the standard of care for follow-up after PTG. METHODS: Through a combination of literature review and two-round Delphi consensus of major HDGC/PTG units and physicians, and patient advocates, we produced a set of recommendations for follow-up after PTG. RESULTS: There were 42 first round, and 62 second round, responses from clinicians, allied health professionals and patient advocates. The guidelines include recommendations for timing of assessments and specialties involved in providing follow-up, micronutrient supplementation and monitoring, bone health and the provision of written information. CONCLUSION: While the evidence supporting the guidelines is limited, expert consensus provides a framework to best manage people following PTG, and could support the collection of information on the long-term effects of PTG.

Alemtuzumab treatment in Denmark: A national study based on the Danish Multiple Sclerosis Registry.

OBJECTIVE: To investigate clinical outcomes in a real-world setting in the complete population-based cohort of alemtuzumab-treated MS patients in Denmark. METHODS: Data were retrieved from The Danish Multiple Sclerosis Registry between 2009 and 2019. Demographic and disease-specific patient parameters related to treatment history, efficacy, and safety outcomes were assessed at baseline and during follow-up visits. RESULTS: A total of 209 patients (78% female) started treatment with alemtuzumab during the study period with 3.1 ± 1.4 years follow-up. After 2 years, 75% of patients were relapse-free compared to 48% the year before alemtuzumab (p < 0.001). The annual number of relapses was reduced by 69% in year 4 compared with the year prior alemtuzumab. More active disease before alemtuzumab increased the annual hazard rate for relapse (HR: 2.88, p < 0.001). The Expanded Disability Status Scale (EDSS) score remained stable or improved in 81% of patients after 2 years. The need for an additional treatment course was associated with higher number of relapses in the year before alemtuzumab (odds ratio (OR) = 1.95, p = 0.001). CONCLUSION: In a country with primarily escalation strategy, relapse rate reduction was maintained for 5 years, and EDSS stabilized/improved in majority of patients. Higher relapse rate 1 year before alemtuzumab increased the odds for additional courses. Novel serious AEs were not observed.

The global antiphospholipid syndrome score in women with systemic lupus erythematosus and adverse pregnancy outcomes.

OBJECTIVES: To validate the global antiphospholipid syndrome score (GAPSS) in a cohort of women with systemic lupus erythematosus (SLE) and antiphospholipid antibodies (aPL). METHODS: This retrospective study included 143 women ever pregnant with SLE who presented in our outpatient clinic were included. Data on cardiovascular risk factors and aPL status were retrospectively collected and their individual GAPSS score was calculated. RESULTS: Significantly higher GAPSS values were found in women with any placental medicated complication (such as foetal death, placental abruption, prematurity, pre-eclampsia or intrauterine growth restriction (IUGR)) (GAPSS 8.2±3.0 vs. 3.5±3.0, p<0.001). Significantly higher GAPSS values were also found in those with recurrent miscarriages (RM) <10 weeks, foetal death, placental abruption, prematurity, pre-eclampsia or IUGR) (GAPSS 8.3±4.5 vs. 3.2±2.6, p<0.001). Patients with 3 or more consecutive early miscarriages (<10 weeks), foetal death, miscarriage <10 weeks' gestation, premature birth (<34 weeks), pre-eclampsia (<34 weeks), stillbirth, and placental infarction had significantly higher GAPSS values compared to those without previous pregnancy complications. The odds ratio of having any pregnancy morbidity when having a GAPSS value ≥8 was 20 compared to those with a GAPSS of ≤1 (p<0.001). CONCLUSIONS: Women with a history of aPL-related pregnancy complications had higher GAPSS values in this retrospective cohort compared to women without pregnancy complications. This study is the first step to assess the clinical utility of the GAPSS score in pregnancy. A prospective validation is needed.

The effect of hydroxychloroquine on platelet activation in model experiments.

Hydroxychloroquine (HCQ) is an antimalarial agent with pleiotropic effects and now represents a cornerstone in the management of patients with autoimmune conditions. While clinical series suggest anti-thrombotic properties, the way in which HCQ exerts this effect remains to be fully explained. Following a 24-h incubation of human umbilical vein endothelial cells (HUVEC) and human umbilical arterial endothelial cells (HUAEC) with HCQ (concentration 500, 1000 and 2000 ng/ml), these cells were then stimulated for an hour with tumor necrosis factor alpha (TNF-α) and were subsequently incubated in direct contact with thrombin-activated platelets. The expression of CD40L on platelets was measured by flow cytometry. The expression of CD40L on platelets significantly increased after direct incubation with 1000 ng/ml and 2000 ng/ml concentrations of HCQ. In contrast, after pre-incubation of HUAECs with 1000 ng/ml HCQ and following stimulation with platelets the expression of CD40L was significantly reduced also after stimulation with thrombin and TNF-α activated platelets. It was shown that the expression of CD40L on the platelets was not significantly reduced by different HCQ concentrations after contact with HCQ pre-incubated HUVECs. HCQ reduces the stimulatory effect of thrombin and TNF-α on platelet activation in the presence of endothelial cells. Our experiments suggest that HCQ pre-incubated HUAEC cells result in a reduced platelets activation measured by means of CD40L expression. Further, our results show that direct HCQ incubation of platelets (without the presence of EC) increased the expression of CD40L suggesting that the observed effect of HCQ on platelet activation may be EC mediated.

Hereditary diffuse gastric cancer: updated clinical practice guidelines.

Hereditary diffuse gastric cancer (HDGC) is an autosomal dominant cancer syndrome that is characterised by a high prevalence of diffuse gastric cancer and lobular breast cancer. It is largely caused by inactivating germline mutations in the tumour suppressor gene CDH1, although pathogenic variants in CTNNA1 occur in a minority of families with HDGC. In this Policy Review, we present updated clinical practice guidelines for HDGC from the International Gastric Cancer Linkage Consortium (IGCLC), which recognise the emerging evidence of variability in gastric cancer risk between families with HDGC, the growing capability of endoscopic and histological surveillance in HDGC, and increased experience of managing long-term sequelae of total gastrectomy in young patients. To redress the balance between the accessibility, cost, and acceptance of genetic testing and the increased identification of pathogenic variant carriers, the HDGC genetic testing criteria have been relaxed, mainly through less restrictive age limits. Prophylactic total gastrectomy remains the recommended option for gastric cancer risk management in pathogenic CDH1 variant carriers. However, there is increasing confidence from the IGCLC that endoscopic surveillance in expert centres can be safely offered to patients who wish to postpone surgery, or to those whose risk of developing gastric cancer is not well defined.

2019 update of EULAR recommendations for vaccination in adult patients with autoimmune inflammatory rheumatic diseases.

To update the European League Against Rheumatism (EULAR) recommendations for vaccination in adult patients with autoimmune inflammatory rheumatic diseases (AIIRD) published in 2011. Four systematic literature reviews were performed regarding the incidence/prevalence of vaccine-preventable infections among patients with AIIRD; efficacy, immunogenicity and safety of vaccines; effect of anti-rheumatic drugs on the response to vaccines; effect of vaccination of household of AIIRDs patients. Subsequently, recommendations were formulated based on the evidence and expert opinion. The updated recommendations comprise six overarching principles and nine recommendations. The former address the need for an annual vaccination status assessment, shared decision-making and timing of vaccination, favouring vaccination during quiescent disease, preferably prior to the initiation of immunosuppression. Non-live vaccines can be safely provided to AIIRD patients regardless of underlying therapy, whereas live-attenuated vaccines may be considered with caution. Influenza and pneumococcal vaccination should be strongly considered for the majority of patients with AIIRD. Tetanus toxoid and human papilloma virus vaccination should be provided to AIIRD patients as recommended for the general population. Hepatitis A, hepatitis B and herpes zoster vaccination should be administered to AIIRD patients at risk. Immunocompetent household members of patients with AIIRD should receive vaccines according to national guidelines, except for the oral poliomyelitis vaccine. Live-attenuated vaccines should be avoided during the first 6 months of life in newborns of mothers treated with biologics during the second half of pregnancy. These 2019 EULAR recommendations provide an up-to-date guidance on the management of vaccinations in patients with AIIRD.

A multicentre study of 244 pregnancies in undifferentiated connective tissue disease: maternal/fetal outcomes and disease evolution.

OBJECTIVES: To investigate fetal/perinatal and maternal outcomes from a large multicentre cohort of women diagnosed with UCTD. METHODS: This multicentre retrospective cohort study describes the outcomes of 224 pregnancies in 133 consecutive women with a diagnosis of UCTD, positive for ANA and aged <45 years old at study inclusion. RESULTS: Of the 224 pregnancies analysed, 177 (79%) resulted in live births, 45 (20.1%) in miscarriages (defined as pregnancy loss before 12 weeks' gestation), 2 (0.9%) in stillbirths (pregnancy loss after 20 weeks' gestation) and 6 (2.7%) cases showed intrauterine growth restriction. Miscarriages and stillbirths were strongly associated with the presence of aPL and ENA antibodies (P < 0.05). Maternal pregnancy complications were as follows: 5 (2.2%) cases developed pre-eclampsia, 11 (4.9%) cases gestational hypertension and 12 (5.4%) cases gestational diabetes. Joint involvement represented the most frequent clinical manifestation of the cohort (57.9%), followed by RP (40.6%), photosensitivity (32.3%) and haematological manifestations (27.1%). The rate of disease evolution of our cohort from a diagnosis of UCTD to a diagnosis of definite CTD was 12% within a mean time of 5.3 ± 2.8 years. With a total follow-up after first pregnancy of 1417 patient-years, we observed the evolution to a defined CTD in one out of every 88 patient- years. CONCLUSION: In our multicentre cohort, women with UCTD had a live birth rate of 79%. Women with UCTD should be referred to specialist follow-up when planning a pregnancy. ENA profiling and aPL testing should be mandatory in this setting, and further therapeutic approaches and management should be planned accordingly.

Hydroxychloroquine and antiphospholipid antibody-related pregnancy morbidity: a systematic review and meta-analysis.

PURPOSE OF REVIEW: Pregnancies in women with antiphospholipid antibodies (aPL) are associated with several pregnancy complications. The current treatment to prevent obstetric aPL-mediated morbidity is largely based on low-dose aspirin (LDA) and low-molecular-weight heparin (LMWH). Alternative treatment regimens to prevent obstetric aPL-related morbidity include the addition of the antimalarial hydroxychloroquine (HCQ). The aim of this systematic review is to identify the currently available evidence on the efficacy of HCQ to prevent aPL-related obstetric morbidity. RECENT FINDINGS: We identified four retrospective observational studies. No definite signal of harm was identified as none of the studies reported adverse outcomes. When comparing a total of 214 aPL-positive women with a total of 250 HCQ-exposed aPL-positive pregnancies and 521 pregnancies not exposed to HCQ, we found that HCQ exposure was not associated with an increased rate of live births [pooled OR 1.33; 95% confidence interval (CI) 0.62--2.86]). There was considerable heterogeneity in the analysis (I = 59%). SUMMARY: HCQ seems well tolerated in pregnancy. However, because of the heterogeneity of available studies, the questions whether women with aPL (or some subpopulation of those) might benefit from this agent during pregnancy remains unanswered. Randomized controlled data are needed.

Functional neuroimaging of recovery from motor conversion disorder: A case report.

A patient with motor conversion disorder presented with a functional paresis of the left hand. After exclusion of structural brain damage, she was repeatedly examined with whole-brain functional magnetic resonance imaging, while she performed visually paced finger-tapping tasks. The dorsal premotor cortex showed a bilateral deactivation in the acute-subacute phase. Recovery from unilateral hand paresis was associated with a gradual increase in task-based activation of the dorsal premotor cortex bilaterally. The right medial prefrontal cortex displayed the opposite pattern, showing initial task-based activation that gradually diminished with recovery. The inverse dynamics of premotor and medial prefrontal activity over time were found during unimanual finger-tapping with the affected and non-affected hand as well as during bimanual finger-tapping. These observations suggest that reduced premotor and increased medial prefrontal activity reflect an effector-independent cortical dysfunction in conversion paresis which gradually disappears in parallel with clinical remission of paresis. The results link the medial prefrontal and dorsal premotor areas to the generation of intentional actions. We hypothesise that an excessive 'veto' signal generated in medial prefrontal cortex along with decreased premotor activity might constitute the functional substrate of conversion disorder. This notion warrants further examination in a larger group of affected patients.

Pregnancy outcomes in mixed connective tissue disease: a multicentre study.

OBJECTIVES: In this study we aimed to investigate foetal and maternal pregnancy outcomes from a large multicentre cohort of women diagnosed with MCTD and anti-U1RNP antibodies. METHODS: This multicentre retrospective cohort study describes the outcomes of 203 pregnancies in 94 consecutive women ever pregnant who fulfilled the established criteria for MCTD with confirmed U1RNP positivity. RESULTS: The foetal outcomes in 203 pregnancies were as follows: 146 (71.9%) live births, 38 (18.7%) miscarriages (first trimester pregnancy loss of <12 weeks gestation), 18 (8.9%) stillbirths (pregnancy loss after 20 weeks gestation) and 11 (5.4%) cases with intrauterine growth restriction. Maternal pregnancy outcomes were as follows: 8 (3.9%) developed pre-eclampsia, 2 (0.9%) developed eclampsia, 31 (15.3%) developed gestational hypertension and 3 (1.5%) developed gestational diabetes. Women with MCTD and aPL and pulmonary or muscular involvement had worse foetal outcomes compared with those without. Moreover, we report a case of complete congenital heart block (0.45%) and a case of cutaneous neonatal lupus, both born to a mother with positive isolated anti-U1RNP and negative anti-Ro/SSA antibodies. CONCLUSION: In our multicentre cohort, women with MCTD had a live birth rate of 72%. While the true frequency of heart block associated with anti-U1RNP remains to be determined, this study might raise the consideration of echocardiographic surveillance in this setting. Pregnancy counselling should be considered in women with MCTD.

The effect of hydroxychloroquine on haemostasis, complement, inflammation and angiogenesis in patients with antiphospholipid antibodies.

Objectives: HCQ has been described as having a beneficial effect in patients with APS but its mechanism of action is unclear. We hypothesized that HCQ may have effects on subnormal angiogenesis, inflammation and haemostatic biomarkers seen in APS. The aim of our study was to assess laboratory markers [annexin A5 (AnxA5) anticoagulant activity, tissue factor (TF) levels, thromboelastography (TEG), CRP, Bb, C3a and VEGF] in HCQ-naïve patients with aPL at baseline and after commencing HCQ. Methods: Twenty-two patients with aPL [20 female, 2 male, median age 55 (range 18-70) years] had blood taken pre- and 3 months after starting HCQ 200 mg daily. Results: Soluble TF levels were significantly reduced comparing baseline and 3 months after HCQ commencement [401.8 (152.8) vs 300.9 (108) pg/ml (P = 0.010)]. No significant changes were found in the following [reported as pre- and post-HCQ commencement, mean (s.d.)]: AnxA5 anticoagulant ratio [187.1 (29.5) vs 193 (31) (P = 0.157)], anti-domain1 ß2 glycoprotein1 IgG activity [1.8 (2) vs 1.2 (1.4) µg/ml (P = 0.105)], complement C3a-des-Arg [147.8 (84.5) vs 154.4 (88.1) ng/ml (P = 0.905)], complement Bb [1.3 (0.7) vs 1.1 (0.7) µg/ml (P = 0.422)], VEGF [68.8 (40) vs 59.4 (19.6) pg/ml (P = 0.454)] and CRP [7 (3.5) vs 7 (3.9) µg/ml (P = 0.917)]. TEG results including TEG reaction time, achievement of clot firmness, TEG maximum amplitude and TEG percentage lysis 30 and 60 min after maximum amplitude showed no significant difference. Conclusion: HCQ significantly reduced soluble TF levels in patients with aPL. No significant change was observed in AnxA5 activity, anti-domain 1 IgG activity, TEG, CRP, complement Bb and C3a-des-Arg, and VEGF. Further studies of a larger patient cohort are needed.
