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 < 0·001) and spent a greater number of their last 90 days of life in hospital (median 19 versus 8 days; P < 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 < 0·001; home: 14·5 versus 23·8 per cent, P < 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.

ANTECEDENTES: Caracterizar la atención al final de la vida en pacientes con amputación de la extremidad inferior por enfermedad arterial periférica (peripheral arterial disease, PAD) o diabetes. MÉTODOS: Se trata de un estudio de cohortes retrospectivo de base poblacional en sujetos fallecidos con PAD o diabetes en Ontario, Canadá (2011-2017). A partir de los registros sanitarios incluidos en un sistema de salud de una sola entidad pagadora, se identificaron los individuos con amputación de la extremidad inferior en los 3 años previos al fallecimiento y una cohorte control de fallecidos con PAD o diabetes sin amputación. Entre las cohortes de amputados y controles se comparó el lugar del fallecimiento y la causa, así como el uso de servicios sanitarios y costes en los últimos 90 días de vida. En el grupo de los amputados, se utilizaron modelos de regresión para caracterizar la asociación entre recibir cuidados paliativos domiciliarios y el fallecimiento en el hospital, así como los días de estancia hospitalaria al final de la vida. RESULTADOS: En comparación con los controles (n = 213.300), los sujetos con amputación (n = 3.113) era menos probable que fallecieran en el domicilio (16% versus 25%, P < 0,001) y pasaron un mayor número de sus últimos 90 días de vida en el hospital (mediana 19 versus 8 días, P < 0,001). Los costes de atención sanitaria al final de la vida en todos los sectores también fueron mayores para los amputados. Sin embargo, recibir cuidados paliativos fue menos frecuente en los amputados que en los controles (en el hospital 13% versus 17%, P < 0,001; domiciliarios 14% versus 24%, P < 0,001). En el grupo de los amputados, recibir cuidados paliativos domiciliarios se asociaba con una menor probabilidad de fallecimiento en el hospital (razón de oportunidades, odds ratio 0,49, i.c. del 95% 0,40-0,60) y menos días de hospitalización (tasa de riesgo 0,84, i.c. del 95% 0,76-0,93). CONCLUSIÓN: Los cuidados paliativos están infrautilizados en pacientes con PAD o diabetes y pueden contribuir a disminuir los fallecimientos en el hospital y los días de hospitalización al final de la vida.

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.

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.

[Adherence to cervical cancer screening in an Italian SLE cohort]. / Aderenza allo screening per il cancro della cervice uterina in una coorte italiana di donne affette da LES.

OBJECTIVE: Papanicolau (Pap) smear abnormalities are more frequently observed in systemic lupus erythematosus (SLE) respect to the general population. The primary objective of the present study was to evaluate the adherence to cervical cancer (CC) screening in an Italian cohort of SLE patients and, secondly, to evaluate the disease-related factors possibly influencing the patients' behavior. METHODS: Consecutive 25 to 64 year old SLE patients and aged- matched healthy women were enrolled for the study. All patients were interviewed during ambulatory visits, at admission to the clinic or by a telephone contact; disease related variables were also collected from the clinical charts. RESULTS: 140 SLE patients (mean age 48.3±12 years) and 70 controls matched for demographic and sociocultural characteristics were enrolled. Ninety-three SLE patients (66.4%) declared to perform the Pap test at least every three years (23.6% yearly and 42.8% when asked by the screening programs) while 47 (33.6%) did not perform regular CC screening (16.4% never did the test and 17.1% only occasionally). No significant differences were observed between patients and controls in cancer screening adherence. No significant associations were observed between the screening program behaviors and disease-related variables. CONCLUSIONS: Despite the growing evidence of an increased risk of CC in SLE, and regardless of the broad availability of screening programs and official recommendations, our results show insufficient CC surveillance among SLE patients and emphasize to rheumatologists and/or general practitioners the importance to discuss with patients this aspect during routine evaluations in order to encourage compliance to the recommended preventive measures.

European League Against Rheumatism recommendations for monitoring patients with systemic lupus erythematosus in clinical practice and in observational studies.

OBJECTIVES: To develop recommendations for monitoring patients with systemic lupus erythematosus (SLE) in clinical practice and observational studies and to develop a standardised core set of variables to monitor SLE. METHODS: We followed the European League Against Rheumatism (EULAR) standardised procedures for guideline development. The following techniques were applied: nominal groups, Delphi surveys for prioritisation, small group discussion, systematic literature review and two Delphi rounds to obtain agreement. The panel included rheumatologists, internists, dermatologists, a nephrologist and an expert related to national research agencies. The level of evidence and grading of recommendations were determined according to the Levels of Evidence and Grades of Recommendations of the Oxford Centre for Evidence-Based Medicine. RESULTS: A total of 10 recommendations have been developed, covering the following aspects: patient assessment, cardiovascular risk factors, other risk factors (osteoporosis, cancer), infection risk (screening, vaccination, monitoring), frequency of assessments, laboratory tests, mucocutaneous involvement, kidney monitoring, neuropsychological manifestations and ophthalmology assessment. A 'core set' of minimal variables for the assessment and monitoring of patients with SLE in clinical practice was developed that included some of the recommendations. In addition to the recommendations, indications for specific organ assessments that were viewed as part of good clinical practice were discussed and included in the flow chart. CONCLUSIONS: A set of recommendations for monitoring patients with SLE in routine clinical practice has been developed. The use of a standardised core set to monitor patients with SLE should facilitate clinical practice, as well as the quality control of care for patients with SLE, and the collection and comparison of data in observational studies.

[Churg-Strauss syndrome: outcome and long-term follow-up of 38 patients from a single Italian centre]. / Caratteristiche clinico-sierologiche e dati di out come di una casistica monocentrica di pazienti affetti da sindrome di Churg-Strauss.

OBJECTIVE: This study was aimed at verifying any potential correlation between anti-myeloperoxidase antineutrophil cytoplasmic antibodies (ANCA-MPO) and clinical features and outcome indices in Churg-Strauss Syndrome (CSS). METHODS: Thirty-eight Churg-Strauss syndrome patients were selected from the medical records of all vasculitis patients attending the Rheumatology and Immunology Unit at the Department of Internal Medicine of the University of Pisa in the decades between 1989 and 2008. Data were analysed retrospectively. Statistical analyses of the results were carried out using the Mann-Whitney test to determine the correlations between the clinical and serological parameters. Qualitative variables were compared using contingency table analysis and Fisher's exact test. RESULTS: ANCA-MPO were detected in15/38 (39%) patients. Positive ANCA status was associated with peripheral neuropathy (p=0.0006), whereas negative ANCA status was associated with lung involvement (p=0.002). Relapses were strongly associated with positive ANCA status (p=0.01) and with an increase in- or a reappearance of ANCA-MPO levels (p=0.006). Finally, ANCA-MPO were significantly associated with neurological damage (p=0.003). CONCLUSIONS: The presence or absence of ANCA-MPO identify different clinical subsets in CSS. Overall, ANCA-MPO appears as a useful tool in the monitoring of CSS and in particular a good predictor of CSS relapses.

Awareness, treatment and control of hyperlipidaemia, hypertension and diabetes mellitus in a selected population of southern Italy.

The purpose of the present study was to assess the degree of awareness, treatment and control of hyperlipidaemia compared with hypertension and diabetes mellitus in a selected population of southern Italy. All participants to a cardiovascular disease prevention campaign examined between April 1994 and July 1995 were screened for hyperlipidaemia, hypertension and diabetes mellitus. Subjects received also ECG, echo-Doppler of carotid arteries and filled in a questionnaire concerning personal and familial cardiovascular diseases, smoking habit and drug consumption. Of the 742 participants, 327 were found to have hypertension, 73 to have diabetes mellitus, 287 to have mild hyperlipidaemia and 322 to have moderate-severe hyperlipidaemia. Among hypertensive subjects, 60.2% were aware of their condition, 53.5% were treated and 15.6% had their blood pressure controlled at the recommended level (< 140/90 mmHg). Among diabetic subjects, 76.7% were aware, 64.4% treated and 19.2% reached fasting blood glucose level of less than 7.77 mmol/l (140 mg/dl). Only 24.0% of subjects with mild hyperlipidaemia were aware of their condition. Of the subjects found to have moderate-severe hyperlipidaemia, 64.9% were aware, 32.3% were treated and 9.0% had plasma cholesterol and triglycerides concentration of less than 6.45 and 5.65 mmol/l (250 and 500 mg/dl), respectively (cutoffs chosen to separate mild from moderate-severe hyperlipidaemia). These results show that mild hyperlipidaemia is almost neglected whereas awareness of moderave-severe hyperlipidaemia is quite widespread and comparable to that of hypertension and diabetes mellitus. Prevalence of treatment and control of moderate-severe hyperlipidaemia is, however, much lower than that of hypertension and diabetes.

[Serum pancreatic enzymes in the diagnosis of carcinoma of the pancreas]. / Gli enzimi pancreatici sierici nella diagnosi del carcinoma pancreatico.

Serum levels of amylase, pancreatic isoamylase, lipase, trypsinogen, and elastase 1 were determined in 41 patients with pancreatic carcinoma and compared with those 71 patients with chronic pancreatitis and 17 patients with digestive non-pancreatic carcinoma, in an attempt to evaluate their relative values in the diagnosis of pancreatic cancer. Trypsinogen and elastase 1 levels were the most frequently abnormal (56%), followed by pancreatic isoamylase (39%), lipase (34%), and amylase (27%). In 4 patients with resectable cancer levels of all serum enzymes were within normal limits, with the single exception of a low trypsinogen level in one patient. No significant differences in the behavior of serum enzymes were found between patients with pancreatic cancer and those with chronic pancreatitis or digestive non-pancreatic cancer. The results of our study indicate that measurement of serum pancreatic enzymes is of limited usefulness in the diagnosis of pancreatic cancer.
