Tumor Necrosis Factor Inhibitor Use Increases Birthweight in Pregnant Women With Rheumatoid Arthritis Independently of the Soluble Fms-Like Tyrosine Kinase-1/Placental Growth Factor Ratio

BACKGROUND: To study whether the use of TNF (tumor necrosis factor) inhibitors (TNFi) by pregnant women with rheumatoid arthritis affects sFlt-1 (soluble Fms-like tyrosine kinase-1), PlGF (placental growth factor), or their impact on birthweight. METHODS AND RESULTS: sFlt-1 and PlGF were measured in all trimesters of pregnancy in the Preconception Counseling in Active Rheumatoid Arthritis study and were compared according to the use of TNFi. The association of sFlt-1 and PlGF with birthweight in relation to TNFi was determined. The study included 158 women, of whom 52.5% used TNFi during pregnancy. Both sFlt-1 and PlGF increased during pregnancy, whereas their ratio declined. Taking into consideration the trimester-related variation in levels of sFlt-1 and PlGF, after correction for relevant confounders, the sFlt-1/PlGF ratio was not significantly different between patients who did or did not use TNFi (sFlt-1/PlGF ratio in the second trimester compared with the first trimester: estimated change 8.17 [95% CI, 2.54-26.29], P=0.79; sFlt-1/PlGF ratio in the third trimester compared with the first trimester: estimated change 6.25 [95% CI, 1.73-22.50], P=0.25). In women who did not use TNFi, birthweight was significantly lower (3180 versus 3302 g; P=0.03), and sFlt-1 displayed a negative correlation with birthweight (r=-0.462, P&lt;0.001) and birthweight percentile (r=-0.332, P=0.008). In TNFi users, these correlations were absent. CONCLUSIONS: TNF inhibitor use increases birthweight in pregnant women with rheumatoid arthritis independently of the sFlt-1/PlGF ratio.

Modern treatment approach results in low disease activity in 90% of pregnant rheumatoid arthritis patients: The PreCARA study

Objectives: In patients with rheumatoid arthritis (RA), high disease activity impairs fertility outcomes and increases the risk of adverse pregnancy outcomes. The aim of this study was to determine the feasibility of a modern treatment approach, including treat-to-target (T2T) and the prescription of tumour necrosis factor (TNF) inhibitors, in patients with RA with a wish to conceive or who are pregnant. Methods: Patients were derived from the Preconception Counseling in Active RA (PreCARA) cohort. Patients with a wish to conceive or who are pregnant were treated according to a modified T2T approach, in which the obvious restrictions of pregnancy were taken into account. Results of the PreCARA study were compared with results of the Pregnancy-induced Amelioration of Rheumatoid Arthritis (PARA) study, a historic reference cohort on RA during pregnancy. Patients in the PARA cohort were treated according to the standards of that time (2002-2010). Differences in disease activity over time between the two cohorts were tested using a linear mixed model. Results: 309 patients with RA were included in the PreCARA study, 188 children were born. 47.3% of the patients used a TNF inhibitor at any time during pregnancy. Mean disease activity over time in the PreCARA cohort was lower than in the reference cohort (p<0.001). In the PreCARA cohort, 75.4% of the patients were in low disease activity (LDA) or remission before pregnancy increasing to 90.4% in the third trimester, whereas in the PARA cohort, these percentages were 33.2% and 47.3%, respectively. Conclusions: This first study on a modern treatment approach in pregnant patients with RA shows that LDA and remission are an attainable goal during pregnancy, with 90.4% of patients achieving this in the third trimester

Tumour necrosis factor inhibitor use during pregnancy is associated with increased birth weight of rheumatoid arthritis patients' offspring

Objectives To study pregnancy outcomes in a closely monitored, well-defined cohort of women with rheumatoid arthritis (RA). In particular, pregnancy outcomes of women that used a TNFi during pregnancy. Methods Patients were derived from a prospective study on pregnancy and RA (Preconception Counseling in Active RA study) and treated according to a treatment protocol aimed at minimal disease activity. Multivariate linear regression analysis was used to describe which variables influenced birth weight. Results 188 patients were included, 92 (48.9%) patients with RA used a TNFi during pregnancy. Disease Activity Score in 28 joints C reactive protein (DAS28CRP) was low at all time points during pregnancy (DAS28CRP in the third trimester: 2.17 (SD 0.73). TNFi use was not associated with an increase of adverse pregnancy outcomes such as low birth weight (<2500 g), (emergency) caesarian section, hypertensive disorders or congenital malformations. TNFi use resulted in less children born small-for-gestational age (p=0.05), however, did not increase the risk of large-for-gestational age (p=0.73). Mean birth weight was 173 g higher in women that used a TNFi during pregnancy (3.344 kg vs 3.171 kg, p=0.03). In the multivariate analysis, maternal age (β -0.023, 95% CI -0.040 to -0.0065, p=0.007), TNFi use (β 0.20, 95% CI 0.066, 0.34, p=0.004), diabetes mellitus (β 0.37, 95% CI 0.12, 0.63, p=0.004) and gestational age (β 0.18, 95% CI 0.15, 0.2, p<0.001) were statistically significant associated with birth weight. Conclusions This is the first study to show that TNFi use during pregnancy is associated with increased birth weight of offspring of women with well-controlled RA. The underlying mechanism of TNF-inhibition on birth weight and the long-term consequences for the offspring should be explored in future research

The sFlt-1 to PlGF ratio in pregnant women with rheumatoid arthritis: impact of disease activity and sulfasalazine use

OBJECTIVES: An elevated sFlt-1/PlGF ratio has been validated as a significant predictor of preeclampsia, but has not been established in women with RA. We explored whether the sFlt-1/PlGFratio could be altered due to disease activity in RA, and could be applied in this population to predict preeclampsia. Since SSZ has been suggested to improve the angiogenic imbalance in preeclampsia, we also aimed to examine whether SSZ could affect sFlt-1 or PlGF levels. METHODS: Making use of a nationwide, observational, prospective cohort study on pregnant women with RA, sFlt-1 and PlGF were measured in the third trimester. A total of 221 women, aged 21-42 years, were included, with a median gestational age of 30 + 3 weeks. RESULTS: No differences in sFlt-1 or PlGF were observed between women with high, intermediate or low disease activity (P = 0.07 and P = 0.41), whereas sFlt-1 and PlGF did not correlate with DAS28-CRP score (r = -0.01 and r = -0.05, respectively). Four (2%) women with a sFlt-1/PlGF ratio ≤38 developed preeclampsia in comparison to three (43%) women with a ratio > 38, corresponding to a negative predictive value of 98.1%. SSZ users (n = 57) did not show altered levels of sFlt-1 or PlGF in comparison to non-SSZ users (n = 164, P = 0.91 and P = 0.11). CONCLUSION: Our study shows that in pregnant women with RA, the sFlt-1/PlGF ratio is not altered due to disease activity and a cut-off ≤38 can be used to exclude preeclampsia. Additionally, SSZ use did not affect sFlt-1 or PlGF levels in this population

Systemic lupus erythematosus and COVID-19 during pregnancy

Background: The ongoing corona virus disease 2019 (COVID-19) pandemic is having a worldwide impact. Valuable information on the clinical characteristics of COVID-19 in pregnant patients with an autoimmune disease, such as systemic lupus erythematosus (SLE), is currently lacking. Methods: Herein, we describe the clinical presentation of 2 pregnant patients with SLE and mild symptomatic COVID-19 infection. Results: In both pregnant SLE patients, a watchful-waiting approach without initiation of treatment for COVID-19 was taken. No adverse outcomes were reported and both pregnancies resulted in healthy neonates born at term. In one patient we observed a flare in SLE disease activity, most likely attributed to discontinuing SLE treatment. Conclusion: Our report highlights the importance of multidisciplinary collaboration between health care professionals as well as individualized treatment decisions during unprecedented periods such as the current COVID-19 pandemic. Discontinuation of immunosuppressive drugs during the acute phase of a COVID-19 infection should be considered on a case-by-case basis. Maternal treatment decisions should be in line with current recommendations for treatment of rheumatic and musculoskeletal diseases during COVID-19 infection and in line with treatment of COVID- 19 during pregnancy

Cam Deformity and Acetabular Dysplasia as Risk Factors for Hip Osteoarthritis

Objective: Cam deformity and acetabular dysplasia have been recognized as relevant risk factors for hip osteoarthritis (OA) in a few prospective studies with limited sample sizes. To date, however, no evidence is available from prospective studies regarding whether the magnitude of these associations differs according to sex, body mass index (

Impaired fertility in men diagnosed with inflammatory arthritis: Results of a large multicentre study (iFAME-Fertility)

Objectives The impact of inflammatory arthritis (IA) on male fertility remains unexplored. Our objective was to evaluate the impact of IA on several male fertility outcomes; fertility rate (number of biological children per man), family planning, childlessness and fertility problems. Methods We performed a multicentre cross-sectional study (iFAME-Fertility). Men with IA 40 years or older who indicated that their family size was complete were invited to participate. Participants completed a questionnaire that included demographic, medical and fertility-related questions. To analyse the impact of IA on fertility rate, patients were divided into groups according to the age at the time of their diagnosis: ≤30 years (before the peak of reproductive age), between 31 and 40 years (during the peak) and ≥41 years (after the peak). Results In total 628 participants diagnosed with IA were included. Men diagnosed ≤30 years had a lower mean number of children (1.32 (SD 1.14)) than men diagnosed between 31 and 40 years (1.60 (SD 1.35)) and men diagnosed ≥41 years (1.88 (SD 1.14)).This was statistically significant (p=0.0004).The percentages of men diagnosed ≤30 and 31-40 years who were involuntary childless (12.03% vs 10.34% vs 3.98%, p=0.001) and who reported having received medical evaluations for fertility problems (20.61%, 20.69% and 11.36%, p=0.027) were statistically significant higher than men diagnosed ≥41 years. Conclusions This is the first study that shows that IA can impair male fertility. Men diagnosed with IA before and during the peak of reproductive age had a lower fertility rate, higher childlessness rate and more fertility problems. Increased awareness and more research into the causes behind this association are urgently needed

Patient Care Pathways for Pregnancy in Rare and Complex Rheumatic Diseases:Results From an International Survey

OBJECTIVE: To map existing organizational care pathways in clinical centers of expertise that care for pregnant women affected by rare and complex connective tissue diseases (rcCTDs). METHODS: An international working group composed of experts in the field of pregnancy in rcCTDs co-designed a survey focused on organizational aspects related to the patient's pathway before, during, and after pregnancy. The survey was distributed to subject experts through referral sampling. RESULTS: Answers were collected from 69 centers in 21 countries. Patients with systemic lupus erythematosus and/or antiphospholipid syndrome were followed by more than 90% of centers, whereas those with disorders such as IgG4-related diseases were rarely covered. In the majority of centers, a multidisciplinary team was involved, including an obstetrician/gynecologist in 91.3% of cases and other healthcare professionals less frequently. Respondents indicated that 96% of the centers provided routine pre-pregnancy care, whereas the number of patient visits during pregnancy varied across centers. A formalized care pathway was described in 49.2% of centers, and 20.3% of centers had a predefined protocol for the monitoring of pregnant patients. Access to therapies during pregnancy also was heterogeneous among different centers. CONCLUSION: In international referral centers, a high level of care is provided to patients with rcCTDs before, during, and after pregnancy. No significant discrepancies were found between European and non-European countries. However, this work highlights a potential benefit to streamlining the care approaches across countries to optimize pregnancy and perinatal outcomes among patients with rcCTDs.</p
