Risk of adverse pregnancy outcomes prior to the onset of an autoimmune rheumatic disease: a systematic review.

OBJECTIVES: An increased risk of adverse maternal and foetal pregnancy complications (including pre-eclampsia, intrauterine growth restriction, and small for gestational age) is well described in women with autoimmune rheumatic disease (ARD) compared with the general population (GenPop). It is less clear, however, whether this risk of adverse pregnancy outcome (APO) also exists in women with 'preclinical ARD' (pre-ARD) before they are diagnosed with an ARD many years post-partum. Therefore, we have undertaken a systematic review of the available evidence on APO in patients who subsequently were diagnosed with a rheumatic disease to identify whether there is an increased risk in pre-ARD. METHODS: The present study was reported in accordance with the guidance of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standard. A systematic literature review was performed using the online PubMed database. Pre-SLE and pre-RA patients were defined as those who, over the subsequent years, developed SLE or RA according to international classification criteria. RESULTS: A total of 176 articles were screened, and 27 original articles were selected for final analysis. Pre-RA was the most studied group, with 15 studies and a total of >1600 pregnancies, and pre-SLE was the second-most studied pre-ARD in pregnancy, with 14 studies and a total of >1000 pregnancies. We found that patients who subsequently developed SLE had an increased burden of poor pregnancy outcomes compared with pregnant women from the GenPop, but fewer APOs compared with pregnancies of women with SLE. In contrast, a similar rate of APOs was found when pre-RA pregnancies were compared with GenPop pregnancies. CONCLUSION: Our findings of an increased risk of APO in certain pre-ARDs highlights the relevance of taking an obstetric history during the first rheumatology appointment and the need for novel screening strategies for the prediction of APOs. Further research is required to elucidate the immune basis of APOs in preclinical and clinical ARD.

A systematic review of live vaccine outcomes in infants exposed to biologic disease modifying anti-rheumatic drugs in utero.

OBJECTIVES: Transplacental passage of certain biologic and targeted synthetic DMARDs leads to detectable levels in the neonate, which may impact on the safety of live vaccines. Guidelines advise delaying live vaccine administration in biologic-exposed infants until they are 7 months old. METHODS: A systematic review of Embase, Medline and Cochrane identified live vaccine outcomes in infants exposed to biologic or targeted synthetic DMARDs in utero. RESULTS: Studies included 276 in utero exposures to adalimumab, certolizumab, etanercept, infliximab, golimumab, tocilizumab and ustekinumab. Live vaccine exposures at <12 months of age included Bacille Calmette-Guérin (BCG) (n = 215), rotavirus (n = 46), and measles, mumps and rubella (MMR) (n = 12). We identified no reactions following MMR, seven mild reactions to rotavirus vaccination and eight reactions to BCG, including one death. All infants with an adverse reaction to BCG had been exposed to infliximab in utero, and six had received BCG in the first month of life. A freedom of information request to the Medicines and Healthcare products Regulatory Agency revealed four fatal disseminated BCG infections in infants exposed to TNF inhibitors in utero, including infliximab, adalimumab and one unspecified TNF inhibitor. CONCLUSION: Most evidence for a clinically harmful effect was for early administration of the BCG vaccine to infants exposed in utero to TNF inhibitors with high transplacental transfer rates.

Major determinants of prolonged remission in systemic lupus erythematosus: retrospective study over a 41+ year period.

OBJECTIVES: To investigate predictors of sustained complete remission (CR) for 3 and 5 years, minimum. METHODS: Retrospective observational study from January 1978 to December 2019, including systemic lupus erythmatosus (SLE) patients who attended the Lupus Clinic in a tertiary hospital, for at least 3 years. We used the BILAG score and serological profile to classify patients into CR, serologically active clinically quiescent (SACQ) and serological remission (SR). Multivariable Cox regression analysis was performed to investigate predictors of CR and Kaplan-Meier curves were obtained. RESULTS: We included 564 patients; 15% achieved CR, 7% SACQ and 15% SR. Some 63% attained no remission. In the CR group, 73% sustained the remission for 5 years or more. Patients who did not reach any kind of sustained remission died significantly earlier (P < 0.001). Cumulative survival figures at 5, 10, 20 and 30 years were 100, 100, 94 and 90%, respectively, for CR patients and 96, 93, 77 and 58%, respectively, for patients in the no-remission group. Significant predictors of CR were White ethnicity [adjusted hazard ratio (HR) 2.16 (95% CI 1.30-3.59); P = 0.003]; older age at diagnosis (>32 years) [HR 1.92 (1.24-2.97); P = 0.003]; absence of renal involvement [HR 2.55 (1.39-4.67); P = 0.002]; and of antiphospholipid syndrome (APS) [HR 4.92 (1.55-15.59); P = 0.007]. CONCLUSION: Patients not achieving any kind of sustained remission have a higher risk of early mortality. White ethnicity, older age at diagnosis, absence of renal involvement and of APS were significantly associated with CR. Predictors for sustained CR do not change whether a 3-year or 5-year period is applied.

Anti-IFNαR Mabs for the treatment of systemic lupus erythematosus.

INTRODUCTION: The type 1 interferon pathway is known to play a role in the immunopathology of systemic lupus erythematosus (SLE). As a result, biologic agents targeting this pathway have been developed and are currently being investigated in clinical trials. AREAS COVERED: We review the biologic agents which have been developed to antagonize type I interferons in SLE. We focus on anifrolumab, a type I interferon receptor antagonist, and consider the complexities of defining efficacy in SLE clinical trials. EXPERT OPINION: Anifrolumab shows promise as an addition to the SLE therapeutic armamentarium. Despite discordant results between its two phase III studies, there is a convincing suggestion of benefit in both trials to encourage the view that this approach might be effective. Data acquired thus far look particularly useful for cutaneous disease. We await data on its effect on renal, pulmonary, cardiac, and central nervous system involvement, on patient reported outcomes, and its safety and efficacy with long-term use.

Play attention! Therapeutic aspects to play in delirium prevention and management.

It is recognised that delirium is common among older adult inpatients and correlated with negative outcomes. The gold standard care for delirium management is achieved using multicomponent interventions. Which components work best is not yet well defined. During the COVID-19 outbreak, a paediatric ward was repurposed to treat adult patients. Paediatric nurses and play specialists remained on the ward. It was observed that the paediatric ward aesthetic and the team's dedicated approach to cognitive stimulation and sleep promotion improved well-being among older adult patients. We propose that elements of paediatric care, primarily deployment of a play specialist, could be incorporated into a multicomponent intervention for delirium prevention and management.

COVID-19-associated hyperinflammation and escalation of patient care: a retrospective longitudinal cohort study.

BACKGROUND: A subset of patients with severe COVID-19 develop a hyperinflammatory syndrome, which might contribute to morbidity and mortality. This study explores a specific phenotype of COVID-19-associated hyperinflammation (COV-HI), and its associations with escalation of respiratory support and survival. METHODS: In this retrospective cohort study, we enrolled consecutive inpatients (aged ≥18 years) admitted to University College London Hospitals and Newcastle upon Tyne Hospitals in the UK with PCR-confirmed COVID-19 during the first wave of community-acquired infection. Demographic data, laboratory tests, and clinical status were recorded from the day of admission until death or discharge, with a minimum follow-up time of 28 days. We defined COV-HI as a C-reactive protein concentration greater than 150 mg/L or doubling within 24 h from greater than 50 mg/L, or a ferritin concentration greater than 1500 µg/L. Respiratory support was categorised as oxygen only, non-invasive ventilation, and intubation. Initial and repeated measures of hyperinflammation were evaluated in relation to the next-day risk of death or need for escalation of respiratory support (as a combined endpoint), using a multi-level logistic regression model. FINDINGS: We included 269 patients admitted to one of the study hospitals between March 1 and March 31, 2020, among whom 178 (66%) were eligible for escalation of respiratory support and 91 (34%) patients were not eligible. Of the whole cohort, 90 (33%) patients met the COV-HI criteria at admission. Despite having a younger median age and lower median Charlson Comorbidity Index scores, a higher proportion of patients with COV-HI on admission died during follow-up (36 [40%] of 90 patients) compared with the patients without COV-HI on admission (46 [26%] of 179). Among the 178 patients who were eligible for full respiratory support, 65 (37%) met the definition for COV-HI at admission, and 67 (74%) of the 90 patients whose respiratory care was escalated met the criteria by the day of escalation. Meeting the COV-HI criteria was significantly associated with the risk of next-day escalation of respiratory support or death (hazard ratio 2·24 [95% CI 1·62-2·87]) after adjustment for age, sex, and comorbidity. INTERPRETATION: Associations between elevated inflammatory markers, escalation of respiratory support, and survival in people with COVID-19 indicate the existence of a high-risk inflammatory phenotype. COV-HI might be useful to stratify patient groups in trial design. FUNDING: None.
