Outcomes and cost analysis of patients with dementia in the intensive care unit: a population-based cohort study

BACKGROUND

Dementia is a neurological syndrome affecting the growing elderly population. While patients with dementia are known to require significant hospital resources, little is known regarding the outcomes and costs of patients admitted to the intensive care unit (ICU) with dementia.

METHODS

We conducted a population-based retrospective cohort study of patients with dementia admitted to the ICU in Ontario, Canada from 2016 to 2019. We described the characteristics and outcomes of these patients alongside those with dementia admitted to non-ICU hospital settings. The primary outcome was hospital mortality but we also assessed length of stay (LOS), discharge disposition, and costs.

RESULTS

Among 114,844 patients with dementia, 11,341 (9.9%) were admitted to the ICU. ICU patients were younger, more comorbid, and had less cognitive impairment (81.8 years, 22.8% had ≥ 3 comorbidities, 47.5% with moderate-severe dementia), compared to those in non-ICU settings (84.2 years, 15.0% had ≥ 3 comorbidities, 54.1% with moderate-severe dementia). Total mean LOS for patients in the ICU group was nearly 20 days, compared to nearly 14 days for the acute care group. Mortality in hospital was nearly three-fold greater in the ICU group compared to non-ICU group (22.2% vs. 8.8%). Total healthcare costs were increased for patients admitted to ICU vs. those in the non-ICU group ($67,201 vs. $54,080).

CONCLUSIONS

We find that patients with dementia admitted to the ICU have longer length of stay, higher in-hospital mortality, and higher total healthcare costs. As our study is primarily descriptive, future studies should investigate comprehensive goals of care planning, severity of illness, preventable costs, and optimizing quality of life in this high risk and vulnerable population.

Exploring disease perception in Behçet's syndrome: combining a quantitative and a qualitative study based on a narrative medicine approach

BACKGROUND

Behçet Syndrome (BS) has a significant psychological and social impact on patients, caregivers and families. The present study aims at exploring disease perception in BS patients, using both a co-designed survey and the narrative medicine (NM) approach.

METHODS

An ad-hoc questionnaire was co-designed by clinicians expert in BS, BS patients and caregivers and BS adult patients were invited to answer the online questionnaires. Cluster analysis was used to analyse data from the survey and to identify groups of patients with diverse disease perception. To further explore real-life perspectives, the stories of illness of a smaller group of adult BS patients were anonymously collected online and analysed by means of text, sentiment and qualitative analysis.

RESULTS

Two hundred and seven patients answered the survey and forty-three stories were collected. The cluster analysis highlighted that accepting or not the disease has a strong impact on the daily life, on how BS patients perceive themselves and in terms of hope for the future. The stories revealed that patients often address common issues, such as the long and complex journey faced from the disease onset until the BS diagnosis, which was strongly connected to the concept of time and perceived as an exhausting period of their lives.

CONCLUSION

To our knowledge, this is the first study that addressed disease perception also applying the NM principles in BS. The current perception that BS patients have of their disease should encourage the BS scientific and patient community in joining forces in order to improve the journey of BS patients.

Sleep quality in Behçet's disease: a systematic literature review

Behçet's Disease (BD) can be correlated with sleep impairment and fatigue, resulting in low quality of life (QoL); however, a comprehensive evaluation of this issue is still missing. We performed a systematic literature review (SLR) of existing evidence in literature regarding sleep quality in BD. Fifteen papers were included in the SLR. Two domains were mainly considered: global sleep characteristics (i) and the identification of specific sleep disorders (ii) in BD patients. From our analysis, it was found that patients affected by BD scored significantly higher Pittsburgh Sleep Quality Index (PSQI) compared to controls. Four papers out of 15 (27%) studied the relationship between sleep disturbance in BD and disease activity and with regards to disease activity measures, BD-Current Activity Form was adopted in all papers, followed by Behçet's Disease Severity (BDS) score, genital ulcer severity score and oral ulcer severity score. Poor sleep quality showed a positive correlation with active disease in 3 out of 4 studies. Six papers reported significant differences between BD patients with and without sleep disturbances regarding specific disease manifestations. Notably, arthritis and genital ulcers were found to be more severe when the PSQI score increased. Our work demonstrated lower quality of sleep in BD patients when compared to the general population, both as altered sleep parameters and higher incidence of specific sleep disorders. A global clinical patient evaluation should thereby include sleep assessment through the creation and adoption of disease-specific and accessible tests.

AB1152 COVID-19 mRNA VACCINE BOOSTER IN PATIENTS WITH SYSTEMIC AUTOIMMUNE DISEASES

Background

Patients with systemic autoimmune diseases (SADs) are often treated with drugs that interfere with the immune system and previous data showed a reduced seroconversion rate after anti-SARS-CoV2 vaccine in these subjects compared to healthy controls1. Administration of a booster dose of the vaccine could be particularly important in these patients, but data available to date are still scarce.

Objectives

To evaluate the antibody response to the booster dose of mRNA SARS-CoV2 vaccine in patients with SADs and to compare it to the response after completion of the first vaccination course. Secondly, to find possible correlations between a low antibody titre and patients’ clinical features, with special regard to ongoing immunosuppressive therapies.

Methods

Consecutive patients with an established diagnosis of SADs undergoing SARS-CoV2 vaccine were prospectively enrolled from January 2021; among them, we selected the patients who received the third vaccination dose between September and December 2021. Demographic and clinical data were collected at enrolment (sex, age, diagnosis, disease duration, ongoing therapies, previous SARS-CoV2 infection, presence of hypogammaglobulinemia); the last three elements were reassessed at each follow-up visit. Blood samples were collected 4 weeks both after the second (W4a) and the third (W4b) dose of the vaccine; a minority of patients was also tested 12 weeks after the second dose (W12). IgG antibodies to SARS-CoV2 receptor-binding domain (RBD) and neutralizing antibodies inhibiting the interaction between RBD and angiotensin converting enzyme 2 were evaluated. IgG anti-RBD were detected by solid phase assay on plates coated with recombinant RBD, while neutralising antibodies by using the kit SPIA (Spike Protein Inhibition Assay). Cut-off values were defined as the 97.5th percentile of a pre-vaccine healthy population. Statistical analysis was performed using IBM SPSS Statistics 20 and GraphPad Prism statistical packages. P values <0.05 were considered significant.

Results

Forty-five patients (95.6% female; mean age ±SD 55.6±14.1 years; mean disease duration 12.9±10.6 years) were enrolled. Diagnosis was in most cases connective tissue disease (31/45, 68.9%), followed by inflammatory arthritis (11/45, 24.4%) and systemic vasculitis (3/45, 6.7%). Two patients (4.4%) had a previous SARS-CoV2 infection and three had hypogammaglobulinemia (6.7%). At the time of the second dose, 18/45 patients were treated with glucocorticoids (GCs) [mean daily 6-methylprednisolone (6MP) dose 3.9 mg (min. 2, max. 14)], 17/45 with conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) and 12/45 with biologic DMARDs (bDMARDs). At the third dose administration, 19/45 patients were treated with GCs [mean daily 6MP dose 4.1 mg (min. 1.5, max. 10)], 18/45 with csDMARDs and 13/45 with bDMARDs. Anti-RBD IgG were positive in 42/45 patients (93.3%) at W4a, in 16/18 (88.9%) at W12 and in 42/45 (93.3%) at W4b. Neutralizing antibodies were present in 38/45 patients (84.4%) at W4a, in 14/18 (77.8%) at W12 and in 42/45 (93.3%) at W4b. Both anti-RBD IgG titers and neutralizing antibody titers significantly increased after the third dose if compared to W4a (p<0.0001 both) (Figure 1). Interestingly, of the 7 patients who had not developed an adequate neutralizing antibody response after the first vaccination course, 5 mounted an adequate titer after the booster. Two non-responder patients were both on combination therapy (one with low dose of GCs plus mycophenolate mofetil, the other with methotrexate and infliximab).

Conclusion

Our data suggest that in patients with SADs there is a decline in the antibody titers developed after COVID-19 vaccination, however the booster dose is effective in restoring an adequate antibody titre. These data consolidate the importance of a booster dose of COVID-19 vaccination in patients with SADs to aid in the generation of an immune response.

POS1232 LONG-TERM OUTCOMES OF COVID-19 VACCINATION IN PATIENTS WITH RARE AND COMPLEX CONNECTIVE TISSUE DISEASES: AN AD-INTERIM ANALYSIS OF ERN-ReCONNET VACCINATE STUDY

Background

Since the COVID-19 vaccination campaign was launched all over Europe, there has been general agreement on how benefits of SARS-CoV2 vaccines outweigh the risks in patients with rare connective tissue diseases (rCTDs). Yet, there is still limited evidence regarding safety and efficacy of such vaccines in these patients, especially in the long-term. For this reason, in the framework of ERN-ReCONNET, an observational long-term study (VACCINATE) was designed in order to explore the long-term outcome of COVID-19 vaccination in rCTDs patients. The consent form was developed thanks to the involvement of the ERN ReCONNET ePAG Advocates (European Patients Advocacy Group).

Objectives

To evaluate the safety profile of COVID-19 vaccination in rCTDs patients and the potential impact on disease activity. Primary endpoints were the prevalence of adverse events (AEs) and of disease exacerbations post-vaccination. Secondary endpoints were the proportion of serious adverse events (SAEs) and adverse events of special interest for COVID-19 (adapted from https://brightoncollaboration.us/wp-content/uploads/2021/01/SO2_D2.1.2_V1.2_COVID-19_AESI-update-23Dec2020-review_final.pdf)

Methods

The first ad-interim analysis of the VACCINATE study involved 9 ERN-ReCONNET Network centres. Patients over 18 years of age with a known rCTD and who received vaccine against COVID-19 were eligible for recruitment. Demographic data and diagnoses were collected at the time of enrolment, while the appearance of AEs and potential disease exacerbations were monitored after one week from each vaccination dose, and then after 4, 12 and 24 weeks from the second dose. A disease exacerbation was defined as at least one of the following: new manifestations attributable to disease activity, hospitalization, increase in PGA from previous evaluation, addition of corticosteroids or immunosuppressants.

Results

A cohort of 300 patients (261 females, mean age 52, range 18-85) was recruited. Systemic lupus erythematosus (44%) and systemic sclerosis (16%) were the most frequent diagnoses, followed by Sjogren’s syndrome (SS,12%), idiopathic inflammatory myositis (IMM,10%), undifferentiated connective tissue disease (UCTD,8%), mixed connective tissue disease (MCTD,4%), Ehlers-Danlos’s syndrome (EDS,4%), antiphospholipid syndrome (APS,2%). AEs appearing 7 days after the first and second doses were reported in 93 (31%) and 96 (32%) patients respectively, mainly represented by fatigue, injection site reaction, headache, fever and myalgia. Otitis, urticaria, Herpes Simplex-related rash, stomatitis, migraine with aura, vertigo, tinnitus and sleepiness were reported with very low frequency. Less than 2% of patients experienced AEs within 24 weeks from the second dose. No SAEs or AEs of special interest were observed in the study period. There were 25 disease exacerbations (8%), 7 of which severe. The highest number of exacerbations was observed after 4 weeks from the second dose (12 within week 4, 6 within week 12 and 7 within week 24). Disease exacerbation was most frequent in patients with EDS (33%) and MCTD (25%).

Conclusion

This preliminary analysis shows that COVID-19 vaccination is safe in rCTDs patients. AEs appear most often early after vaccination and are usually mild. Disease exacerbations are not frequent, but can be potentially severe and tend to occur most frequently within the first month after vaccination. Exacerbations can also occur 3-6 months after vaccination, although a causal relationship with the vaccination remains to be established. Our present data underline the importance of long-term observational studies.

AB0588 GIANT CELL ARTERITIS: DO DIFFERENT PHENOTYPES OF PRESENTATION MEAN DIFFERENT CLINICAL ENTITIES?

Background

Giant cell arteritis (GCA) represents the most common primary vasculitis of the elderly, affecting large and medium-sized arterial vessels. GCA often also involves the aorta and its major branches and may lead to aortic aneurysm/dissection as well as large artery stenoses; it seems that unrecognized extra-cranial involvement may be even more common.

Objectives

The primary aim of this study was to explore the different clinical entities in a large cohort of patients with GCA; a secondary aim was to evaluate long-term outcome of GCA patients with at least 5 years of follow-up.

Methods

A cohort of 278 GCA patients (54 males and 224 females, mean ± SD age 75 ± 6 years) were retrospectively studied. Clinical symptoms at disease onset and during the follow-up, time delay until diagnosis, as well as laboratory findings at the time of diagnosis and therapeutic approach were retrospective evaluated. In order to characterize the different clinical phenotypes, overall clinical symptoms were grouped for macro-area (cranial versus systemic). Moreover, long-term outcomes in patients with a minimum follow-up of 3 years were evaluated. A disease flare was defined as the presence of any further clinical manifestation compatible with the clinical spectrum of GCA and an increase of ESR ≥ 30 mm/hour, not otherwise justifiable, that required higher doses or new introduction of glucocorticoids (GC) therapy and/or the introduction of steroid sparing treatments (e.g. tocilizumab, methotrexate).

Results

The most frequent clinical manifestations presented at the onset included: constitutional symptoms 69%, new onset headache and/or scalp pain 64%, jaw claudicatio 32%, vision loss 30%, abnormal temporal artery on examination 19%, neuropsychiatric symptoms 17%, cough not otherwise justifiable 7%, cerebrovascular accidents 6% and hearing loss 3%. Irreversible (mono- or bilateral) blindness was reported in 7% of patients, mainly due to a latency period between onset and treatment of ≥ 3 months. Temporal artery biopsy was performed in 171 patients, resulting positive in 72%. Globally, about 38% of subjects (was characterized by a clinical profile compatible with extra-cranial GCA. In all cases, extra-cranial involvement was confirmed by (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET). Moreover, patients who presented symptoms compatible with large-vessel involvement were characterized by a more relapsing course compared with patients with cranial involvement GCA profile (both in terms of dose of corticosteroids and use of steroid-sparing agents).

Conclusion

According to the literature data, different phenotypes of GCA exist and they may probably represent different clinical entities, also in terms of prognosis and therapeutic approach. This is particularly crucial in order to plan a tailored therapy and prevent disease damage in the short and long-term follow-up.

P110 ACCIDENTAL FINDING OF COR TRIATRIUM SINISTER IN AN ADULT: DIAGNOSIS MANAGMENT

A 45–year old woman presented at the emergency department for palpitations and fever. The EKG, thoracic x–ray and troponins were normal, only a neutrophil leucocytosis was found. The echocardiography showed a normal bi–ventricular and valvular function and a mobile, linear, mass in the left atrium. In order to exclude an infective vegetation the patient underwent to a 2D and 3D transesophageal echocardiography (Figure 1 and 2) which showed a left ventricle concentric remodelling (iLVmass 62 g/m2; RWT 0.45), preserved left and right ventricle function (LVEF according to Simpson 70%; FAC 50%) and valves function; inter–atrial septum defects were excluded, too. The mass was described as a mobile membrane in the left atrium at 2.11 cm from the mitral valve anular plane, which divided the atrium into two separate chambers with a large fenestration without trans–mitralic flow obstruction, supporting a cor triatrium sinister. We excluded endocarditis (the blood cultures were negative, too) and supra–valvular mitral ring (since the left appendage position in the antero–inferior side of the left atrium). The cardiac MRI showed (Figure 3) (SSFP–FIESTA, IR–GRE T1, STIR T2) confirmed the finding of a left atrium divided in two chamber by a iso–intense membraine from the coumadin ridge between the left upper pulmonary vein and the left appendage to the inter–atrial septum fossa ovalis, incomplete in the infero–lateral part. Venous drenaige and other congenital abnormalities were excluded. Miocarditis was excluded since no fibrosis in IR–GRE T1 and no edema in Triple T2 sequences. Since the non–obstructive cor triatrium sinister, grading IA according the Lucas classification, was confirmed, no surgical treatment was proposed and the patient was discharged without complications.

Empowering rare disease patients through patient education: the new BehçeTalk programme

BACKGROUND

Educating patients and caregivers on their disease can improve their knowledge and promote the active involvement in the therapeutic decision-making process. Naturally, patient education programmes are critically important in rare systemic autoimmune diseases, where relevant knowledge and expertise still remain scattered. Behçet's disease (BD) represents a challenging rare condition, characterized by a variable spectrum of disease profile and a relapsing course.

RESULTS

Recently, BehçeTalk, an educational programme tailored for BD patients, families and caregivers with, was launched. BehçeTalk, entirely co-designed with BD patients, is offering educational on-line webinars on different aspects of the disease, as well support groups for patients and caregivers coordinated by a psychologist with specific expertise in BD.

CONCLUSIONS

The therapeutical management of BD is often challenging and frequently includes off-label treatments. Considering the specificities of BD, providing a specific education on the disease to patients will lead to empower them in being part of the decision-making processes, in the self-management and in improving their quality of life.

A257 PANCREATIC CANCER TREATMENT AND END OF LIFE OUTCOMES: A POPULATION BASED COHORT STUDY

Background

Patients with pancreatic cancer face challenging decisions regarding treatment choices following their diagnosis and often lack data on end-of-life (EOL) outcomes. Without the available information, older patients may be undertreated, dying earlier than they would have with treatment, while others may be overtreated and exposed to aggressive measures with harmful side effects.

Aims

To describe survival and EOL outcomes among pancreatic cancer patients based on index cancer treatment, disease stage, and patient characteristics.

Methods

We conducted a population based cohort study in Ontario, Canada of patients who died from April 2010 to December 2017 and were diagnosed with pancreatic cancer prior to death. We used administrative databases to collect data on demographics, baseline health status, treatments, and outcomes. The primary exposure was index cancer treatment (no treatment, radiation, chemotherapy alone, surgery alone, and surgery with chemotherapy). The primary outcomes were mortality, health care encounters per 30 days in the last six months of life, and palliative care visits per 30 days within the last six months of life. Secondary outcomes were location of death (institution vs. community), hospitalization within the last 30 days of life, and receipt of chemotherapy within the last 30 days of life. We estimated the association between the exposure and outcomes using multivariable models, adjusting for demographics, comorbidities, and cancer stage. Hazard ratios, adjusted mean differences, and odds ratios were reported with 95% confidence intervals.

Results

Our cohort included 9950 adults with a median age at diagnosis of 78. 56% received no index treatment, 5% underwent radiation, 27% underwent chemotherapy alone, 7% underwent surgery alone, and 6% underwent surgery and chemotherapy. In the multivariable regression (Table and Figure), radiation, chemotherapy alone, surgery alone, and surgery with chemotherapy were all associated with decreased mortality and fewer healthcare encounters. All groups except radiation were associated with fewer palliative care visits. All treatment groups were associated with lower odds of institutional death and hospitalization within the last 30 days of life, and higher odds of chemotherapy within the last 30 days of life.

Conclusions

Our data, the first to provide EOL outcome estimates based on index cancer treatment, can help patients make initial treatment decisions after a diagnosis of pancreatic cancer.

A systematic literature review of existing tools used to assess medication adherence in connective tissue diseases: the state of the art for the future development of co-designed measurement tools

Lack of medication adherence is frequent in chronic connective tissue diseases and is associated with poorer health outcomes, low quality of life and economic loss. This research is based on a systematic literature search and aims to identify the surveys and tools used for the assessment of medication adherence in patients with connective tissue diseases (CTDs) and in particular the tools co-designed with patients. A systematic literature review was performed in PubMed and Embase databases searching for studies concerning the application of surveys or tools designed for medication adherence assessment. A specific analysis was also performed to identify which of these existing tools were developed in co-design with patients affected by CTDs. 1958 references were identified, and 31 studies were finally included. Systemic lupus erythematosus was the most investigated disease, followed by the Behçet's disease. The tools used to assess adherence in CTDs were, in most cases, valid and useful. However, the results showed a certain degree of heterogeneity among the studies and the medication adherence assessment and measurement tools adopted, which were mostly based on selfreported questionnaire. No co-designed tools with patients were found. Low- and non-adherence were explored in some CTDs with valid and useful tools, while other CTDs still need to be assessed. Therefore, more efforts should be made to better understand the specific reasons for the low- and non-adherence in CTDs patients.

FRI0221 GIANT CELL ARTERITIS PRESENTING AS FEVER OF UNKNOWN ORIGIN AND DELAY IN DIAGNOSIS: ANALYSIS OF TWO DIFFERENT DECADES

Background:

Giant cell arteritis (GCA) represents the most common primary vasculitis of the elderly, that usually involves large and medium sized arteries. The wide spectrum of clinical manifestations can extensively vary, from cranial symptoms, such as headache, jaw claudication or visual alterations, to constitutional symptoms, like fever, weight loss or asthenia. Fever of unknown origin (FUO) may sometimes represents the initial symptom of GCA and when it is not associated with other typical GCA features, the diagnosis can be unluckily delayed.

Objectives:

The primary aim of the study was to identify the prevalence of GCA patients presenting as FUO. The secondary aims were to identify the delays in the diagnosis and to compare them between the last two decades.

Methods:

Epidemiological and clinical data of 274 GCA patients followed in the last 20 years in our Unit were analysed. We quantified the latency period between the onset of signs and symptoms and the final diagnosis of GCA in terms of months.

Results:

One hundred and eighty-five patients (49 males and 136 females, mean ± SD age at the onset 71±7 years) had shown at the onset signs and symptoms suggestive of GCA (new onset headache and/or scalp pain 86%, jaw claudication 39%, vision loss 35%, abnormal temporal artery on examination 49%, dizziness 31%) while 89 patients (33 males and 56 females, mean age at the onset 69±4 years) were sent to our attention just for the onset of FUO and for an increase of erythrocyte sedimentation rate and C-reactive protein not otherwise justified. After an extensive work-up aimed at excluding any kind of infection, malignancy or hematological disorder, the patients with FUO performed a temporal artery biopsy (TAB) and/or a (18)F-fluorodeoxyglucose positron emission tomography (18F-FDG PET). The results from histology and/or imaging allowed us to perform the diagnosis of GCA in all cases; moreover the main PET alterations reported were characterized by a (18)FDG uptake of the aortic arch and its major braches, including the carotid, subclavian, thoracic aorta and, less frequently, the abdominal aorta. Considering the different decades, the mean latency period between the onset of FUO and the diagnosis of GCA was 6±3 months in the decade from 2000 to 2010 and 3±2 months in the last decade, that was significantly higher compared with the mean latency period between the onset of signs and symptoms suggestive of GCA and the definitive diagnosis (3±1 months) in the other patients of the cohort in the first decade. Notably the latency period between the onset of signs and symptoms suggestive of GCA and the definitive diagnosis was more close (2±1 months) to the latency period of diagnosis in FUO presenting GCA in the last decade.

Conclusion:

Our data underline that there is a major focus on the diagnosis of GCA, even when the presentation is not typical; this is probably due to the major knowledge reached in the last decade, to an improved sensibilization regarding the different profiles of presentation and surely on the bigger use of 18F-FDG PET in the work-up of GCA patients.

AB0532 CORRELATION WITH THE FREQUENCY OF DISEASE RELAPSES DURING THE FIRST 3 YEARS FROM THE DIAGNOSIS AND DISEASE OUTCOMES IN BEHCET’S SYNDROME

Background:

Beside the organ involvement, a number of demographic factors could considerably influence the long-term and short-term outcomes of Behçet’s syndrome (BS): age at disease onset, duration of disease, gender and sex. Younger men patients are more suitable to have a more severe disease, due to an increased frequency both of morbidity and mortality, related to ocular,vascular and neurological involvement

Objectives:

The primary aims of the study were to evaluate disease activity in a cohort of BS patients consecutively followed in a BS clinic of a tertiary centre and to explore whether there is a correlation between frequency of relapses in the first 3 years of diseases and disease outcomes.

Methods:

One-hundred and sixty-five patients (91 males and 74 females; mean age 39±9 years, mean disease duration 9±5) with a diagnosis of BS according to the ISG criteria were studied. Disease activity has been evaluated by BDCAF and patients were also categorized in major or minor involvement of BS according or not to the presence of ocular, neurological and vascular involvement in the course of disease The numbers of relapses in the first 3 years from diagnosis were correlated with disease outcome and damage.

Results:

At time of the evaluation, 47% of BS patients presented an active disease; 69 patients presented muco-cutaneous involvement, 39 ocular disease, 21 joint involvement, 12 neurological impairment and 9 gastro-enteric involvement. Seventy-nine percent of patients presented in the course of the disease a severe BS involvement and the majority was represented by patients characterised by a more frequent relapse in the first 3 years of disease (M/F: 65/48, mean age 43±3 years). Those patients who experienced a more higher number of relapse in the first 3 years compared to the others were also characterised by poor disease outcomes and worse prognosis over time and this correlation was independent by the therapies taken.

Conclusion:

The high frequency of relapses during the first three years from diagnosis may be considered an important prognostic factor for disease outcome in BS patients, therefore could be taken into account as a useful element to tailor the management, not only according to the type and severity of symptoms and epidemiological factors.

End-of-life care following leg amputation in patients with peripheral artery disease or diabetes

Background

The aim was to characterize end-of-life care in patients who have had a leg amputated for peripheral artery disease (PAD) or diabetes.

Methods

This was a population-based retrospective cohort study of patients with PAD or diabetes who died in Ontario, Canada, between 2011 and 2017. Those who had a leg amputation within 3 years of death were compared with a control cohort of deceased patients with PAD or diabetes, but without leg amputation. The patients were identified from linked health records within the single-payer healthcare system. Place and cause of death, as well as health services and costs within 90 days of death, were compared between the amputee and control cohorts. Among amputees, multivariable regression models were used to characterize the association between receipt of home palliative care and in-hospital death, as well as time spent in hospital at the end of life.

Results

Compared with 213 300 controls, 3113 amputees were less likely to die at home (15·5 versus 24·9 per cent; P &lt; 0·001) and spent a greater number of their last 90 days of life in hospital (median 19 versus 8 days; P &lt; 0·001). Amputees also had higher end-of-life healthcare costs across all sectors. However, receipt of palliative care was less frequent among amputees than controls (inpatient: 13·4 versus 16·8 per cent, P &lt; 0·001; home: 14·5 versus 23·8 per cent, P &lt; 0·001). Among amputees, receipt of home palliative care was associated with a lower likelihood of in-hospital death (odds ratio 0·49, 95 per cent c.i. 0·40 to 0·60) and fewer days in hospital (rate ratio 0·84, 0·76 to 0·93).

Conclusion

Palliative care is underused after amputation in patients with PAD or diabetes, and could contribute to reducing in-hospital death and time spent in hospital at the end of life.

Immunometabolic biomarkers of inflammation in Behçet's disease: relationship with epidemiological profile, disease activity and therapeutic regimens

Behcet's disease (BD) is a systemic inflammatory disease with a still unclear pathogenesis. Although several inflammatory molecules have been studied, current biomarkers are largely insensitive in BD and unable to predict disease progression and response to treatment. Our primary aim was to explore serum levels of soluble CD40 L (sCD40L), soluble intracellular adhesion molecule (sICAM-1), monocyte chemoattractant protein-1 (MCP-1), myeloperoxidase (MPO), leptin, resistin, osteoprotegerin (OPG), soluble type 1 tumour necrosis factor receptor (sTNFR), interleukin (IL)-6 and serum amyloid A (SAA) serum concentration in a cohort of 27 BD patients. The secondary aim was to evaluate potential correlations between the putative circulating biomarkers, demographic profile of patients, the status of disease activity, the specific organ involvement at the time of sample collection and different therapeutic regimens. Serum concentrations of sTNFR (P = 0·008), leptin (P = 0·0011), sCD40L (P < 0·0001) and IL-6 (P = 0·0154) were significantly higher in BD patients than in HC, while no difference was found in MCP-1, MPO and resistin serum levels. Moreover, we observed significantly higher sTNFR serum concentrations in BD patients presenting inactive disease than HC (P = 0·0108). A correlation between sTNFR and age was also found, with higher levels in patients over 40 years than HC (P = 0·0329). Although further research is warranted to elucidate the role of circulating biomarkers, some of that may contribute to the understanding of the physiopathology processes underlying BD activity and damage as well as to provide useful tools for prognostic purposes and a personalized treatment approach.

Systemic vasculitides: a critical digest of the most recent literature

Herewith we provide our annual digest of the recent literature on systemic vasculitides. In this manuscript, we reviewed all the articles published during the last 12 months on large-, medium- and small-vessel vasculitis and selected the most relevant studies regarding the epidemiology, pathogenesis and management of systemic vasculitis. In particular, we focused the attention on giant cell arteritis, ANCA-associated vasculitis and cryoglobulinaemia.

Pain in Sjögren's syndrome

Sjögren's syndrome (SjS) is an autoimmune disease that affects the salivary and lacrimal glands, but it can also have extra-glandular manifestations. Although pain has not yet been fully studied and characterized, it is a symptom that can be often found in patients with SjS, who mainly complain of neuropathic pain, followed by nociceptive pain. The latter when combined with widespread dysfunctional symptoms is defined fibromyalgia. The aim of this work is to analyze the scientific literature on the presence of pain in patients with primary Sjögren's syndrome.

Systematic review of 2008-2012 literature and update of recommendations for the use of methotrexate in rheumatic diseases, with a focus on rheumatoid arthritis

The objective of this review is to update the recommendations of the 2010 Italian Consensus on the use of methotrexate (MTX) in rheumatoid arthritis (RA) and other rheumatic diseases. The literature published between 2008 and 2012 was systematically reviewed and updated recommendations on MTX use in rheumatic diseases, particularly RA, were formulated. These recommendations were approved by a panel of expert Italian Rheumatologists. A total of 10,238 references were identified, among which 70 studies were selected for critical evaluation. Sufficient evidence had accumulated to warrant changes to several of the recommendations in the new version. A new recommendation for patients with RA who are in MTX-induced clinical remission was also proposed and approved by the panel. Updated recommendations for the use of MTX in patients with RA or other rheumatologic disease are proposed.

Analysis of the prevalence of cataracts and glaucoma in systemic lupus erythematosus and evaluation of the rheumatologists' practice for the monitoring of glucocorticoid eye toxicity

Chronic glucocorticoid (GC) therapy is associated with an increased risk of developing cataracts and glaucoma, and recommendations have been developed for monitoring these side effects in patients with rheumatic diseases. The aim of this study was to assess the prevalence of cataracts and glaucoma and the adherence to the existing recommendations for monitoring eye toxicity of chronic GC therapy among systemic lupus erythematosus (SLE) patients in routine clinical practice. Clinical charts of 170 patients were examined, and 34 (20%) of them never underwent an eye assessment. The remaining 136 underwent an eye assessment with an interval of 75 ± 61.7 months. Only 45 (33%) had received an evaluation during the previous 12 months. All these 170 patients were taking chronic CG therapy at a mean daily dose of 5.4 ± 2.4 mg prednisone and a mean cumulative dose of 27.6 ± 20.5 g. Out of the 136 patients with at least one eye assessment, cataracts were observed in 39 patients (29%) and glaucoma in 4 patients (3%). Cataracts were diagnosed at a mean age of 46.5 ± 10 years; the development of cataracts was associated with age, disease duration, and cumulative GC dose. Glaucoma was diagnosed at a mean age of 40.5 ± 16 years; due to the small number of patients, no correlations were made. The prevalence of cataracts and glaucoma is higher than in the general population, and these conditions occur early in the life of SLE patients. An association between GC and cataracts is confirmed. The adherence to recommendations is suboptimal as only 33% of patients underwent an eye assessment over the previous 12 months. These data reinforce the need to improve adherence to recommendations for eye monitoring among SLE patients under chronic therapy with GC.
