Short- and Long-Term Mortality of Hospitalized Patients With Autoimmune Rheumatic Diseases and Serious Infections: A National Cohort Study.

OBJECTIVE: Infectious conditions are a significant cause of mortality in autoimmune rheumatic diseases (ARD). Among patients hospitalized with an infection, we compared in-hospital and long-term (3-year) mortality between those with and without ARD. METHODS: This retrospective analysis included members of the largest health maintenance organization in Israel, aged > 18 years at the first episode of infection, who required hospitalization during 2003-2019. We compared in-hospital mortality and the results of a 3-year landmark analysis of those who survived the index hospitalization between patients with ARD, according to disease subgroups, and patients without ARD. Additionally, we compared mortality outcomes among patients with ARD, according to subgroup diagnosis, matched in a 1:3 ratio by age, sex, and ethnicity to patients without ARD. RESULTS: Included were 365,247 patients who were admitted for the first time with the diagnosis of a serious infection. Of these, we identified 9755 with rheumatoid arthritis (RA), 1351 with systemic lupus erythematosus, 2120 with spondyloarthritis (SpA), 584 with systemic sclerosis, and 3214 with vasculitis. In a matched multivariate analysis, the risk for in-hospital mortality was lower among patients with RA (odds ratio [OR] 0.89, 95% CI 0.81-0.97) and SpA (OR 0.77, 95% CI 0.63-0.94). In a similar analysis, the risk of 3-year mortality was lower among patients with RA (hazard ratio [HR] 0.82, 95% CI 0.78-0.86) and vasculitis (HR 0.86, 95% CI 0.80-0.93). CONCLUSION: Among patients hospitalized for an infection, the risk of in-hospital and 3-year mortality was not increased among those with ARD compared to those without ARD.

The Diagnostic profile and clinical course of patients with rheumatic diseases in the medical intensive care unit.

Background/aim: Immunosuppressive and immunomodulatory treatments developed in recent years as a result of a better understanding of the pathophysiology of systemic rheumatic diseases (SRDs) improve the prognosis. Despite medical advances, individuals with SRDs at any stage may require intensive care and have a high mortality rate. The aim of this study was to investigate the demographic and clinical characteristics of patients with rheumatic diseases admitted to the intensive care unit (ICU), and the factors associated with the risk of mortality. Materials and methods: This was a retrospective, cross-sectional study that included patients with rheumatic diseases in the medical ICU. Factors of ICU 28-day mortality were identified by multiple-variable logistic analysis. Results: A total of 127 patients with SRDs admitted to the medical ICU were enrolled. Systemic lupus erythematosus (SLE) (32.3%) was the most common diagnosis of SRDs in patients admitted to the ICU. The reasons for admission to the ICU were combined infection and primary SRD flare-up (35.4%), primary SRD flare-up (22%), SRD-unrelated reasons (22%), infection (17.3%), drug side effects (3.9%), and SRD-related complications (0.8%). The most common organ dysfunctions before (49.6%) and during (77.2%) admission to ICU were in the respiratory system. The 28-day mortality was 78 (61.4%). While the maximum procalcitonin, serum lactate, and blood urea nitrogen (BUN) levels were higher in the nonsurvivor group, the platelet and serum albumin levels were statistically significantly lower than those in the survivor group (p < 0.05). Acute respiratory failure (ARF), the presence of septic shock, the need for invasive mechanical ventilation (IMV), BUN level, and low platelet-lymphocyte ratio (PLR) were significant in the final multiple-variable model. Conclusion: Significant predictors of mortality in patients with rheumatic diseases may include ARF, septic shock, the need for IMV, and high BUN and low PLR levels.

COVID-19 infection, admission and death among people with rare autoimmune rheumatic disease in England: results from the RECORDER project.

OBJECTIVES: To calculate the rates of COVID-19 infection and COVID-19-related death among people with rare autoimmune rheumatic diseases (RAIRD) during the first wave of the COVID-19 pandemic in England compared with the general population. METHODS: We used Hospital Episode Statistics to identify all people alive on 1 March 2020 with ICD-10 codes for RAIRD from the whole population of England. We used linked national health records (demographic, death certificate, admissions and PCR testing data) to calculate rates of COVID-19 infection and death up to 31 July 2020. Our primary definition of COVID-19-related death was mention of COVID-19 on the death certificate. General population data from Public Health England and the Office for National Statistics were used for comparison. We also describe COVID-19-related hospital admissions and all-cause deaths. RESULTS: We identified a cohort of 168 680 people with RAIRD, of whom 1874 (1.11%) had a positive COVID-19 PCR test. The age-standardized infection rate was 1.54 (95% CI: 1.50, 1.59) times higher than in the general population. A total of 713 (0.42%) people with RAIRD died with COVID-19 on their death certificate and the age-sex-standardized mortality rate for COVID-19-related death was 2.41 (2.30-2.53) times higher than in the general population. There was no evidence of an increase in deaths from other causes in the RAIRD population. CONCLUSIONS: During the first wave of COVID-19 in England, people with RAIRD had a 54% increased risk of COVID-19 infection and more than twice the risk of COVID-19-related death compared with the general population. These increases were seen despite shielding policies.

Factors associated with COVID-19-related death in people with rheumatic diseases: results from the COVID-19 Global Rheumatology Alliance physician-reported registry.

OBJECTIVES: To determine factors associated with COVID-19-related death in people with rheumatic diseases. METHODS: Physician-reported registry of adults with rheumatic disease and confirmed or presumptive COVID-19 (from 24 March to 1 July 2020). The primary outcome was COVID-19-related death. Age, sex, smoking status, comorbidities, rheumatic disease diagnosis, disease activity and medications were included as covariates in multivariable logistic regression models. Analyses were further stratified according to rheumatic disease category. RESULTS: Of 3729 patients (mean age 57 years, 68% female), 390 (10.5%) died. Independent factors associated with COVID-19-related death were age (66-75 years: OR 3.00, 95% CI 2.13 to 4.22; >75 years: 6.18, 4.47 to 8.53; both vs ≤65 years), male sex (1.46, 1.11 to 1.91), hypertension combined with cardiovascular disease (1.89, 1.31 to 2.73), chronic lung disease (1.68, 1.26 to 2.25) and prednisolone-equivalent dosage >10 mg/day (1.69, 1.18 to 2.41; vs no glucocorticoid intake). Moderate/high disease activity (vs remission/low disease activity) was associated with higher odds of death (1.87, 1.27 to 2.77). Rituximab (4.04, 2.32 to 7.03), sulfasalazine (3.60, 1.66 to 7.78), immunosuppressants (azathioprine, cyclophosphamide, ciclosporin, mycophenolate or tacrolimus: 2.22, 1.43 to 3.46) and not receiving any disease-modifying anti-rheumatic drug (DMARD) (2.11, 1.48 to 3.01) were associated with higher odds of death, compared with methotrexate monotherapy. Other synthetic/biological DMARDs were not associated with COVID-19-related death. CONCLUSION: Among people with rheumatic disease, COVID-19-related death was associated with known general factors (older age, male sex and specific comorbidities) and disease-specific factors (disease activity and specific medications). The association with moderate/high disease activity highlights the importance of adequate disease control with DMARDs, preferably without increasing glucocorticoid dosages. Caution may be required with rituximab, sulfasalazine and some immunosuppressants.

Clinical characteristics and outcomes of patients with coronavirus disease 2019 (COVID-19) and rheumatic disease: a comparative cohort study from a US 'hot spot'.

OBJECTIVE: To investigate differences in manifestations and outcomes of coronavirus disease 2019 (COVID-19) infection between those with and without rheumatic disease. METHODS: We conducted a comparative cohort study of patients with rheumatic disease and COVID-19 (confirmed by severe acute respiratory syndrome coronavirus 2 PCR), compared in a 1:2 ratio with matched comparators on age, sex and date of COVID-19 diagnosis, between 1 March and 8 April 2020, at Partners HealthCare System in the greater Boston, Massachusetts area. We examined differences in demographics, clinical features and outcomes of COVID-19 infection. The main outcomes were hospitalisation, intensive care admission, mechanical ventilation and mortality. RESULTS: We identified 52 rheumatic disease patients with COVID-19 (mean age, 63 years; 69% female) and matched these to 104 non-rheumatic disease comparators. The majority (39, 75%) of patients with rheumatic disease were on immunosuppressive medications. Patients with and without rheumatic disease had similar symptoms and laboratory findings. A similar proportion of patients with and without rheumatic disease were hospitalised (23 (44%) vs 42 (40%)), p=0.50) but those with rheumatic disease required intensive care admission and mechanical ventilation more often (11 (48%) vs 7 (18%), multivariable OR 3.11 (95% CI 1.07 to 9.05)). Mortality was similar between the two groups (3 (6%) vs 4 (4%), p=0.69). CONCLUSIONS: Patients with rheumatic disease and COVID-19 infection were more likely to require mechanical ventilation but had similar clinical features and hospitalisation rates as those without rheumatic disease. These findings have important implications for patients with rheumatic disease but require further validation.

Effectiveness and safety of lower dose sulfamethoxazole/trimethoprim therapy for Pneumocystis jirovecii pneumonia in patients with systemic rheumatic diseases: A retrospective multicenter study.

OBJECTIVES: To evaluate the effectiveness and safety of lower-dose sulfamethoxazole/trimethoprim therapy (SMX/TMP) for Pneumocystis jirovecii pneumonia (PCP) in patients with systemic rheumatic diseases. METHODS: In this multicenter retrospective study, we compared effectiveness and safety of SMX/TMP for the treatment of PCP among patients divided into three groups according to the initial dosage of SMX/TMP: the low, ≤10 mg/kg/day; the intermediate, 10-15 mg/kg/day; and the high and conventional, 15-20 mg/kg/day for TMP dose. RESULTS: Eighty-one patients, including 22, 30, and 29 patients in the low-, the intermediate- and the high-dose group could be analyzed and the 30-day survival rate were 100%, 93.3%, and 96.7%, respectively (P = 0.28). There were significant dose-dependent increasing trends of severe adverse drug reactions (ADRs) for SMX/TMP that were graded as ≥3 according to the Common Terminology Criteria for Adverse Events. When stratified by presence of severe hypoxemia defined by alveolar-arterial O2 gradient ≥45 mmHg, the 30-day survival and treatment modification rate were similar among the three groups, but frequency of severe ADRs were significantly decreased in the low-dose group. The low-dose group was independently and negatively associated with treatment modification within 14 days and severe ADRs. CONCLUSIONS: Lower dose SMX/TMP therapy with ≤10 mg/kg/day for TMP was as effective as higher dose therapy for the treatment of PCP and associated with lower rates of treatment modification and severe ADRs in patients with systemic rheumatic diseases.

Survival of adults with systemic autoimmune rheumatic diseases and pulmonary arterial hypertension after lung transplantation.

Objectives: Pulmonary arterial hypertension (PAH) is a major cause of morbidity and mortality in adults with systemic autoimmune rheumatic diseases (ARDs). The aim of this study was to determine whether adults with ARDs and PAH on right-sided heart catheterization (ARD-PAH) have increased mortality following lung transplantation compared with those with PAH not due to an ARD. Methods: We conducted a retrospective cohort study of 93 adults with ARD-PAH and 222 adults with PAH who underwent lung transplantation in the USA between 4 May 2005 and 9 March 2015 using data from the United Network for Organ Sharing. We examined associations between diagnosis and survival after lung transplantation using stratified Cox models adjusted for potential confounding recipient factors. Results: Among adults undergoing lung transplantation in the USA, we did not detect a difference in the multivariable-adjusted mortality rate between those with ARD-PAH and those with PAH [hazard ratio 0.75 (95% CI 0.47, 1.19)]. Conclusion: The presence of an ARD was not associated with increased mortality after lung transplantation in adults with PAH.

Simple screening tools predict death and cardiovascular events in patients with rheumatic disease.

OBJECTIVES: Patients with rheumatic disease (RD) have an increased mortality risk compared with the general population, mainly due to cardiovascular disease (CVD). We aimed to identify patients at high risk of CVD and mortality by comparing three screening tools suitable for clinical practice. METHOD: In this prospective, single-centre study, consecutive patients with rheumatoid arthritis (RA), systemic autoimmune disease (SAI), or spondyloarthritides (SpA) including psoriatic arthritis underwent a comprehensive cardiovascular risk assessment. Patients were predefined as being at high risk for cardiovascular events or death if any of the following were present: European Systematic COronary Risk Evaluation (SCORE) ≥ 3%, N-terminal pro-brain natriuretic peptide (NT-proBNP) ≥ 200 pg/mL, or any pathological electrocardiogram pattern. RESULTS: The patient population (n = 764) comprised 352 patients with RA, 260 with SAI, and 152 with SpA. After a median follow-up of 5.2 years, 6.0% of RD patients had died (7.0%, 7.2%, and 1.4% of patients in the RA, SAI, and SpA subgroups), and 5.0% had experienced a cardiovascular event (5.0%, 6.4%, and 2.8%, respectively). For all RD patients and the RA and SAI subgroups, NT-proBNP ≥ 200 pg/mL and SCORE ≥ 3% identified patients with a 3.5-5-fold increased risk of all-cause death and cardiovascular events. Electrocardiogram pathology was associated with increased mortality risk, but not with cardiovascular events. CONCLUSION: NT-proBNP ≥ 200 pg/mL or SCORE ≥ 3% identifies RA and SAI patients with increased risk of cardiovascular events and death. Both tools are suitable as easy screening tools in daily practice to identify patients at risk for further diagnostics and closer long-term follow-up.

Health-related quality of life in patients with chronic rheumatic disease after a multidisciplinary rehabilitation regimen.

INTRODUCTION: Multidisciplinary rehabilitation has beneficial effects on health-related quality of life (HRQoL) in patients with chronic rheumatic diseases. However, whether this intervention benefits different age groups in women or men is largely unknown. PURPOSE: To investigate HRQoL in patients with chronic rheumatic disease after completion of a 3-week multidisciplinary treatment, with special focus on differences in effect between age and gender groups. METHOD: HRQoL was measured with SF-36. Mean scores for all SF-36 domains were compared before and after the 3-week regimen and again at 3-, 6-, and 12-month follow-ups. Multivariable linear regression models using generalized estimating equations to account for repeated measurement were employed. A weighting procedure to account for differential dropouts was applied. RESULTS: Three hundred fifty-six women and 74 men with chronic rheumatic disease were included. There were short-term improvements in all SF-36 domains irrespective of age or gender. These effects persisted for up to 1 year in the psychological, social, and energy domains for women under 50. We found no lasting effects for men; however, young men showed similar trends. CONCLUSION: Inpatient multidisciplinary rehabilitation improves short-term HRQoL in all patients. Younger women maintain these beneficial effects for up to 1 year. Additional intervention should be considered for elderly women and for men in order to sustain rehabilitation effects.

[Outcome of intensive medical care for inflammatory rheumatic diseases]. / Outcome intensivmedizinischer Betreuung bei rheumatischen Erkrankungen.

BACKGROUND AND OBJECTIVE: Very little is known about the outcome of patients with inflammatory rheumatic diseases in intensive care units (ICU). This retrospective study investigated the results of intensive medical treatment in these patients and the reliability of scoring systems used for the prediction of survival. MATERIAL AND METHODS: A case group consisting of 50 patients suffering from inflammatory rheumatic diseases was generated by analysis of patient records from the ICU at the University Hospital for Internal Medicine in Halle (Saale) in the years 2001-2010. The APACHE II score and SAPS II were used to estimate the probable mortality rate. The data were compared to those of a control group consisting of 72 patients treated on the ICU and suffering from non-inflammatory joint diseases. RESULTS: In the case group a higher mortality rate (38 % vs. 20.8 %) and a higher frequency of respiratory, nephrogenic and cardiovascular complications were observed. In addition, these patients more often underwent artificial ventilation (66 % vs. 35 %) and had a higher rate of infections (74 % vs. 40.3 %) compared to the control group. In patients with inflammatory rheumatic diseases the SAPS II was not useful for correctly predicting mortality, whereas the APACHE II score showed sufficient agreement with the actual mortality rate. CONCLUSION: Patients with inflammatory rheumatic diseases displayed a poorer outcome compared with the control group in the course of the intensive care treatment. Universally applied scoring systems used to predict mortality are of limited value in this patient population.

[Prognosis and therapy of inflammatory rheumatic diseases : Impact of renal manifestations]. / Prognose und Therapie von entzündlich-rheumatischen Erkrankungen : Einfluss der Nierenbeteiligung.

BACKGROUND: Inflammatory rheumatic diseases and their treatment cause various renal manifestations requiring modification of treatment. OBJECTIVES: Discussion of renal manifestations in selected rheumatic diseases, including their impact on general prognosis and therapy. MATERIALS AND METHODS: Basic literature and expert opinions are analyzed and discussed. RESULTS: Inflammatory rheumatic diseases and their treatment cause various renal manifestations, including glomerular, tubular, interstitial, and vascular damage. The type of damage determines both, associated clinical symptoms (i.e. hematuria, proteinuria, loss of kidney function) and the renal and overall survival as will be discussed here for rheumatoid arthritis, systemic lupus erythematosus, scleroderma, Sjögrens syndrome, cryoglobulinemia and ANCA-associated vasculitis. CONCLUSION: Renal manifestations are generally indicators of high disease activity and usually require more intensive treatment of the underlying rheumatic disease. Early and rigorous treatment, which has to be adapted to renal function, is capable of improving renal and overall survival in many of the affected patients.

Cardiovascular Morbidity and Mortality Among Working Individuals With Rheumatic Disease: Results From a Large Prospective Cohort Study.

BACKGROUND: Cardiovascular comorbidities are common in rheumatic diseases and are associated with an increased mortality risk but have not been studied in a working population, with less severe disease. Also, the impact of premature cardiovascular mortality on work participation has been neglected until now. OBJECTIVES: The objectives of this study were to evaluate the cardiovascular risk in working individuals with inflammatory rheumatic diseases and to explore whether cardiovascular morbidity and mortality are associated with decreased work participation in this population. METHODS: Employees from 45 companies in The Netherlands (n = 12,140) were prospectively followed up from 1998 onward by annual questionnaires. Data covering 10 years of follow-up was available (1998-2008) for rheumatic and cardiovascular morbidities. Self-reported rheumatic and cardiovascular diseases were verified by clinical review in hospital records in a subsample living in 1 specific region of The Netherlands. Information on the vital status was obtained by linking our records to national registries. Cox proportional hazards models were used to determine the contribution of cardiovascular comorbidity on mortality, with adjustment for confounders. RESULTS: In the sample verified by clinical review, the 10-year risk of developing cardiovascular diseases tended to be increased in workers with inflammatory rheumatic diseases (n = 17) at baseline (relative risk, 2.30; 95% confidence interval [CI], 0.91-5.81) and was significantly increased in those with gout (n = 18) at baseline (relative risk, 3.64; 95% CI, 1.64-8.09) as compared with those without inflammatory rheumatic diseases or gout, respectively. Gout (n = 31; hazard ratio, 4.19; 95% CI, 1.33-13.25) and cardiovascular diseases (n = 206; hazard ratio, 2.19; 95% CI, 1.24-3.84) were significantly related to 10-year mortality. No deaths had occurred in individuals with inflammatory rheumatic diseases during follow-up. CONCLUSIONS: In this study, gout was significantly associated with cardiovascular comorbidity and mortality, but inflammatory rheumatic diseases were not. Decreased work participation in workers with gout and potentially inflammatory rheumatic diseases can be expected because of an increased morbidity but not mortality risk.

Adalimumab: long-term safety in 23 458 patients from global clinical trials in rheumatoid arthritis, juvenile idiopathic arthritis, ankylosing spondylitis, psoriatic arthritis, psoriasis and Crohn's disease.

BACKGROUND: As long-term treatment with antitumour necrosis factor (TNF) drugs becomes accepted practice, the risk assessment requires an understanding of anti-TNF long-term safety. Registry safety data in rheumatoid arthritis (RA) are available, but these patients may not be monitored as closely as patients in a clinical trial. Cross-indication safety reviews of available anti-TNF agents are limited. OBJECTIVE: To analyse the long-term safety of adalimumab treatment. METHODS: This analysis included 23 458 patients exposed to adalimumab in 71 global clinical trials in RA, juvenile idiopathic arthritis, ankylosing spondylitis (AS), psoriatic arthritis, psoriasis (Ps) and Crohn's disease (CD). Events per 100 patient-years were calculated using events reported after the first dose through 70 days after the last dose. Standardised incidence rates for malignancies were calculated using a National Cancer Institute database. Standardised death rates were calculated using WHO data. RESULTS: The most frequently reported serious adverse events across indications were infections with greatest incidence in RA and CD trials. Overall malignancy rates for adalimumab-treated patients were as expected for the general population; the incidence of lymphoma was increased in patients with RA, but within the range expected in RA without anti-TNF therapy; non-melanoma skin cancer incidence was raised in RA, Ps and CD. In all indications, death rates were lower than, or equivalent to, those expected in the general population. CONCLUSIONS: Analysis of adverse events of interest through nearly 12 years of adalimumab exposure in clinical trials across indications demonstrated individual differences in rates by disease populations, no new safety signals and a safety profile consistent with known information about the anti-TNF class.

Malignancy as a comorbidity in rheumatic diseases.

Patients with systemic autoimmune rheumatic diseases, particularly RA, SLE, SS and idiopathic inflammatory myopathies, are at increased risk of developing malignancies. Cancer occurrence adds to the disease burden in these patients, adversely affecting quality of life and life expectancy. This risk is related to the pathobiology of the underlying rheumatic disease including the inflammatory burden, immunological defects, and personal and environmental exposure such as smoking and some viral infections. Immunomodulatory therapies, especially chemotherapeutic agents, are also associated with an increased risk of cancer in these conditions. The decision to use immunomodulating therapies in patients with rheumatic disease must take into account the disease severity, expectations for disease control, comorbidities and host and environmental risk factors for cancer. Effective screening and monitoring strategies are important in reducing the risk of cancer in these patients.

An update on stem cell transplantation in autoimmune rheumatologic disorders.

Stem cell transplant (SCT) has long been the standard of care for several hematologic, immunodeficient, and oncologic disorders. Recently, SCT has become an increasingly utilized therapy for refractory autoimmune rheumatologic disorders (ARDs). The efficacy of SCT in ARDs has been attributed to resetting an aberrant immune system either through direct immune replacement with hematopoietic stem cells or through immunomodulation with mesenchymal stem cells. Among ARDs, refractory systemic sclerosis (SSc) and systemic lupus erythematosus (SLE) are the most common indications for SCT. SCT has also been used in refractory rheumatoid arthritis, inflammatory myopathies, antiphospholipid syndrome, granulomatosis with polyangiitis, and pediatric ARDs. Complete responses have been reported in approximately 30 % of patients in all disease categories. Transplant-related mortality, however, remains a concern. Future large multi-center prospective randomized clinical trials will help to better define the specific role of SCT in the treatment of patients with ARDs.

Life expectancy, standardized mortality ratios, and causes of death in six rheumatic diseases in Hong Kong, China.

OBJECTIVE: To examine the life expectancy, standardized mortality ratios (SMRs), and causes of death in 6 groups of patients from Hong Kong with different rheumatic diseases. METHODS: Patients with a diagnosis of systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PsA), systemic vasculitis (SV), or systemic sclerosis (SSc) registered in 37 public hospitals between 1999 and 2008 were identified in the hospital registry. SMRs were calculated by comparing the mortality rate in patients with each disease with that in the general population. Life expectancy was calculated by abridged life-table analysis, and the causes of death were compared. RESULTS: In 2008, data on 8,367 RA, 5,243 SLE, 2,154 AS, 1,636 SV, 778 PsA, and 449 SSc patients were available in our registry. The age- and sex-adjusted SMRs were highest for SLE (5.25 [95% confidence interval 4.79-5.70]), SSc (3.94 [95% confidence interval 3.20-4.68]), and SV (2.64 [95% confidence interval 2.36-2.93]). In female patients, the loss in life expectancy was greatest for SSc (34.1 years), SV (19.3 years), and SLE (19.7 years). In male patients, the loss in life expectancy was highest for SV (28.3 years), SLE (27 years), and SSc (16 years). There were 2,486 deaths during the study period (1999-2008), and the principal causes were infections (28%), cardiovascular complications (18%), cancer (16%), and disease activity (7%). Infection was the leading cause of death in SLE, RA, AS, and PsA, whereas deaths from disease-related activity and cardiovascular complications were most frequent in SSc. Cancer was the most common cause of death in SV. CONCLUSION: Our findings indicate that patients with SLE, RA, AS, PsA, SV, and SSc have increased mortality rates and reduced life expectancy. SLE has the highest adjusted SMR, and female SSc patients have the greatest loss in life expectancy. Infection is the leading cause of death, followed by cardiovascular complications and malignancies.

Pediatric rheumatic disease in the intensive care unit: lessons learned from 15 years of experience in a tertiary care pediatric hospital.

OBJECTIVE: This study describes the 15-yr experience of a large urban tertiary care children's hospital in treating critically ill patients with pediatric rheumatic diseases. DESIGN: Retrospective case series. SETTING: Children's Hospital Los Angeles, a large urban tertiary care children's hospital. PATIENTS: All patients with pediatric rheumatic diseases admitted to the Children's Hospital Los Angeles pediatric intensive care unit from January 1995 to July 2009. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: An internal database and medical records were reviewed for demographics, diagnoses, treatments, organ dysfunction, interventions, infections, and outcomes. Standardized mortality ratio was calculated based on Pediatric Risk of Mortality III estimated mortality. Factors associated with mortality were identified by univariate analyses.Ninety patients with 122 total admissions were identified. The majority of patients were Hispanic (63%), female (73%), and had systemic lupus erythematosus (62%). Pediatric rheumatic disease-related complications (50%) were the most common reason for admission; 32% of admissions involved multiorgan dysfunction. Eighteen admissions (15%) resulted in mortality. Deaths were most commonly attributed to combined infection and active rheumatic disease (50%), infection only (22%), rheumatic disease only (11%), or other causes (17%). In 30 (25%) admissions, a new rheumatologic diagnosis was established. Standardized mortality ratio was 0.72 (95% confidence interval 0.38-1.25) for pediatric rheumatic disease patients compared to 0.87 (95% confidence interval 0.79-0.96) for all pediatric intensive care unit patients. Factors associated with mortality included use of mechanical ventilation, vasopressors, and renal replacement (continuous venovenous hemodialysis) (all p < .05). CONCLUSIONS: Pediatric rheumatic disease-related complications were the principal cause of pediatric intensive care unit admission. Deaths occurred most often from severe infections in patients with active rheumatic disease. Pediatric rheumatology patients admitted to the pediatric intensive care unit had outcomes similar to the global pediatric intensive care unit population when adjusted for severity of illness.

Short- and long-term prognosis of acute critically ill patients with systemic rheumatic diseases: A retrospective multicentre study.

ABSTRACT: Patients with systemic rheumatic disease (SRD) share the risks of multi-organ flare-up, cardiovascular diseases, and immunosuppression. Such situations can lead to an acute critical illness. The present study describes the clinical features of SRD patients admitted to the intensive care unit (ICU) and their short- and long- term mortality.We performed a multicentre retrospective study in 10 French ICU in Lyon, France. Inclusion criteria were SRD diagnosis and admission for an acute organ failure. The primary endpoint was ICU mortality.A total of 271 patients were included. SRD included systemic lupus erythematosus (23.2% of included patients), vasculitis (10.7%), systemic sclerosis (10.7%), idiopathic inflammatory myopathy (6.3%), and other connective tissue disorders (rheumatoid arthritis, Sjögren and Sharp syndromes; 50.9%). Initial organ failure(s) were shock (43.5% of included patients), acute kidney injury (30.5%), and acute respiratory failure (23.2%). The cause(s) of ICU admission included sepsis (61.6%), cardiovascular events (33.9%), SRD-flare up (32.8%), and decompensations related to comorbidities (28%). The ICU mortality reached 14.3%. The factors associated with ICU mortality were chronic cardiac failure, invasive ventilation and admission in ICU for another reason than sepsis or SRD flare-up. The median follow-up after ICU discharge was 33.6 months. During follow-up, 109 patients died. The factors associated with long-term mortality included age, Charlson comorbidity index, and ICU admission for sepsis or SRD flare-up.The ICU mortality of patients with SRD was low. Sepsis was the first cause of admission. Cardiovascular events and comorbidities negatively impacted ICU mortality. Admission for sepsis or SRD flare-up exerted a negative effect on the long-term outcome.

The Influence of Corticosteroids, Immunosuppressants and Biologics on Patients With Inflammatory Bowel Diseases, Psoriasis and Rheumatic Diseases in the Era of COVID-19: A Review of Current Evidence.

Patients with inflammatory bowel disease, psoriasis or other rheumatic diseases treated with corticosteroids, immunomodulators and biologics might face additional risk during COVID-19 epidemic due to their immunocompromised status. However, there was still no unanimous opinion on the use of these therapy during COVID-19 epidemic. Current studies suggested that systemic corticosteroids might increase the risk of hospitalization, as well as risks of ventilation, ICU, and death among patients with immune-mediated inflammatory diseases. Anti-TNF agent was associated with lower rate of hospitalization, as well as lower risks of ventilation, ICU, and death. No significant changes in rates of hospitalization, ventilation, ICU and mortality were observed in patients treated with immunomodulators or biologics apart from anti-TNF agents. The underlying mechanism of these results might be related to pathway of antiviral immune response and cytokine storm induced by SARS-COV-2 infection. Decision on the use of corticosteroids, immunomodulators and biologics should be made after weighing the benefits and potential risks based on individual patients.

COVID-19 Among Patients With Inflammatory Rheumatic Diseases.

BACKGROUND: The course of novel coronavirus disease 2019 (COVID-19) has been of special concern in patients with inflammatory rheumatic diseases (IRDs) due to the immune dysregulation that may be associated with these diseases and the medications used for IRDs, that may affect innate immune responses. OBJECTIVE: In this cohort study, we aimed to report the disease characteristics and variables associated with COVID-19 outcome among Turkish patients with IRDs. METHODS: Between April and June, 2020, 167 adult IRD patients with COVID-19 were registered from 31 centers in 14 cities in Turkey. Disease outcome was classified in 4 categories; (i) outpatient management, (ii) hospitalization without oxygen requirement, (iii) hospitalization with oxygen requirement, and (iv) intensive care unit (ICU) admission or death. Multivariable ordinal logistic regression analysis was conducted to determine variables associated with a worse outcome. RESULTS: 165 patients (mean age: 50 ± 15.6 years, 58.2% female) were included. Twenty-four patients (14.5%) recovered under outpatient management, 141 (85.5%) were hospitalized, 49 (30%) required inpatient oxygen support, 22 (13%) were treated in the ICU (17 received invasive mechanic ventilation) and 16 (10%) died. Glucocorticoid use (OR: 4.53, 95%CI 1.65-12.76), chronic kidney disease (OR: 12.8, 95%CI 2.25-103.5), pulmonary disease (OR: 2.66, 95%CI 1.08-6.61) and obesity (OR: 3.7, 95%CI 1.01-13.87) were associated with a worse outcome. Biologic disease-modifying antirheumatic drugs (DMARDs) do not seem to affect COVID-19 outcome while conventional synthetic DMARDs may have a protective effect (OR: 0.36, 95%CI 0.17-0.75). Estimates for the associations between IRD diagnoses and outcome were inconclusive. CONCLUSIONS: Among IRD patients with COVID-19, comorbidities and glucocorticoid use were associated with a worse outcome, while biologic DMARDs do not seem to be associated with a worse outcome.
