Objective: To determine how mental disorders and psychopharmacological treatments before and during COVID-19 hospital admissions are related to mortality., Methods: Subjects included in the study were all adult patients with a diagnosis of COVID-19, confirmed clinically and by PCR, who were admitted to a tertiary university hospital in Badalona (Spain) between March 1 and November 17, 2020. Data were extracted anonymously from computerized clinical records., Results: 2,150 subjects were included, 57% males, mean age 61 years. History of mental disorders was registered in 957 (45%). Throughout admission, de novo diagnosis of mood or anxiety, stress, or adjustment disorder was made in 12% of patients without previous history. Delirium was diagnosed in 10% of cases. 1011 patients (47%) received a psychotropic prescription during admission (36% benzodiazepines, 22% antidepressants, and 21% antipsychotics). Mortality rate was 17%. Delirium during admission and history of mood disorder were independently associated with higher mortality risk (hazard ratios, 1.39 and 1.52 respectively), while previous year's treatments with anxiolytics/hypnotics and antidepressants were independently associated with lower mortality risk (hazard ratios, 0.47 and 0.43, respectively)., Conclusion: Mental symptoms are very common in patients hospitalized for COVID-19 infection. Detecting, diagnosing, and treating them is key to determining the prognosis of the disease and functional recovery., (© 2021 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background: Epidemiological data suggest that some viruses may be linked to the development of autoimmunity., Objectives: The objective of this work was to determine the presence of HHV-8 viral DNA in whole blood from patients suffering from different systemic autoimmune diseases (SAD). We also aimed at testing the prevalence of patients showing antibodies against an HHV-8 orfK8.1 peptide., Study Design: Two hundred and eighty SAD patients and 50 healthy blood donor controls were included. Molecular analyses were performed by nested PCR from DNA obtained from whole blood and an enzyme immunoassay was developed in order to test for the presence of antibodies directed against a synthetic peptide derived from the HHV-8 orfK8.1 protein., Results: Only 2 out of the 280 samples analyzed yielded the specific HHV-8 PCR product. Antibodies against orfK8.1 were detected in 2 SLE patients, 1 patient suffering from Sjögren's syndrome and 2 patients with vasculitis., Conclusions: We conclude that HHV-8 is usually not present in blood neither from autoimmune patients nor from healthy controls. Furthermore, HHV-8 antibodies against the HHV-8 orfK8.1 peptide were rarely detected. It leads us to infer that HHV-8 is not involved on the development of these disorders. It does not rule out the possibility that other environmental and microbiological triggers may account for their etiopathogenesis., (Copyright © 2014 Elsevier B.V. All rights reserved.)

Introduction: Increased expression of IL-33 and its receptor ST2, encoded by the IL1RL1 gene, has been detected in the inflamed arteries of giant cell arteritis (GCA) patients. The aim of the present study was to investigate for the first time the potential influence of the IL33 and IL1RL1 loci on GCA predisposition., Methods: A total of 1,363 biopsy-proven GCA patients and 3,908 healthy controls from four European cohorts (Spain, Italy, Germany and Norway) were combined in a meta-analysis. Six genetic variants: rs3939286, rs7025417 and rs7044343, within the IL33 gene, and rs2058660, rs2310173 and rs13015714, within the IL1RL1 gene, previously associated with immune-related diseases, were genotyped using predesigned TaqMan assays., Results: A consistent association between the rs7025417 polymorphism and GCA was evident in the overall meta-analysis, under both allele (P(MH) = 0.041, OR = 0.88, CI 95% 0.78-0.99) and recessive (P(MH) = 3.40E-03, OR = 0.53, CI 95% 0.35-0.80) models. No statistically significant differences between allele or genotype frequencies for the other IL33 and IL1RL1 genetic variants were detected in this pooled analysis., Conclusions: Our results clearly evidenced the implication of the IL33 rs7025417 polymorphism in the genetic network underlying GCA.

Objective: Different lines of evidence have highlighted the role of IL-17A in the inflammatory process occurring in giant cell arteritis (GCA). The aim of the present study was to assess whether the IL17A locus influences GCA susceptibility and its clinical subphenotypes., Methods: We carried out a large meta-analysis including a total of 1266 biopsy-proven GCA patients and 3779 healthy controls from four European populations (Spain, Italy, Germany and Norway). Five IL17A polymorphisms (rs4711998, rs8193036, rs3819024, rs2275913 and rs7747909) were selected by tagging and genotyped using TaqMan assays. Allelic combination and dependency tests were also performed., Results: In the pooled analysis, two of the five analysed polymorphisms showed evidence of association with GCA (rs2275913: PMH=1.85E-03, OR=1.17 (1.06-1.29); rs7747909: PMH=8.49E-03, OR=1.15 (1.04-1.27)). A clear trend of association was also found for the rs4711998 variant (PMH=0.059, OR=1.11 (1.00-1.23)). An independent effect of rs2275913 and rs4711998 was evident by conditional regression analysis. In addition, the haplotype harbouring the risk alleles better explained the observed association than the polymorphisms independently (likelihood p value <10(-05))., Conclusions: Polymorphisms within the IL17A locus show a novel association with GCA. This finding supports the relevant role of the Th17 cells in this vasculitis pathophysiology., (Published by the BMJ Publishing Group Limited.

Objectives: The Xq28 region, containing IRAK and MECP2, represent a common susceptibility locus for a high number of autoimmune diseases. Our aim in the present study was to evaluate the influence of the IRAK1 and MECP2 autoimmunity-associated genetic variants in the giant cell arteritis (GCA) susceptibility and its clinical subphenotypes., Methods: We analysed a total of 627 female biopsy-proven GCA patients and 1,520 female healthy controls of Spanish Caucasian origin. Two polymorphisms, rs1059702 and rs17345, located at IRAK1 and MECP2, respectively, were genotyped using TaqMan® allelic discrimination assays., Results: No association with any of the analysed polymorphisms was evident when genotype and allele frequencies were compared between GCA patients and controls (rs1059702: allelic p-value=0.699, OR=0.96, CI 95% 0.80-1.17; rs17435: allelic p-value=0.994, OR=1.00, CI 95% 0.84-1.19). Likewise, the subphenotype analysis yield similar negative results., Conclusions: We have assessed for the first time the possible role of IRAK1 and MECP2 autoimmune disease-associated polymorphisms in GCA. Our data suggest that IRAK1 rs1059702 and MECP2 rs17435 genetic variants do not play a significant role in GCA susceptibility or severity.

Objective: To evaluate systemic involvement in primary SS in a large cohort of Spanish patients using the EULAR-SS disease activity index (ESSDAI) definitions., Methods: Systemic involvement was characterized using ESSDAI definitions for the 10 clinical domains (constitutional, lymphadenopathy, glandular, articular, cutaneous, pulmonary, renal, peripheral nervous system, central nervous system and muscular). ESSDAI scores at diagnosis, during follow-up and cumulated at the last visit were calculated., Results: The cohort consisted of 921 patients. After a mean follow-up of 75 months, 77 (8%) patients still had an ESSDAI score of zero at the last visit. Organ by organ, the percentage of patients who developed activity during the follow-up (ESSDAI score ≥ 1 at any time) ranged between 1.4% and 56%, with articular, pulmonary and peripheral neurological involvement being the most common. Logistic multivariate regression analysis showed the following features at diagnosis and had the closest association with systemic activity (statistically significant independent variables in at least two domains): cryoglobulinaemia in five domains; anaemia, lymphopenia and low C3 levels in three domains each and age <35 years in two domains. Sicca features, ANA and RF at diagnosis were not associated with a higher cumulated activity score in any clinical domain., Conclusion: Primary SS is undeniably a systemic disease, with the joints, lungs, skin and peripheral nerves being the most frequently involved organs. Cytopenias, hypocomplementaemia and cryoglobulinaemia at diagnosis strongly correlated with higher cumulated ESSDAI scores in the clinical domains. Clinically the ESSDAI provides a reliable picture of systemic involvement in primary SS.

Aim: Deprivation has been linked to more complicated and uncontrolled diabetes. The validated Évaluation de la précarité et des inégalités de santé dans les centres d'examens de santé (EPICES; Evaluation of the Deprivation and Inequalities of Health in Healthcare Centres) score could help to identify such deprived patients. The present study evaluated the relationships between deprivation and prevalence of complications, uncontrolled diabetes and quality of life., Methods: This prospective study was conducted in the diabetology department of a tertiary university hospital from November 2006 to July 2007. Patients with diabetes were divided into two groups, according to their deprivation status [non-deprived: EPICES score<30.17; deprived: EPICES score≥30.17 (56.5%)]. Diabetes control, complications and quality of life [Short Form Health Survey (SF-36)] were compared in the two groups., Results: Of a total of 102 patients, 97 completed all of the questionnaires: 18 had type 1 diabetes and 79 had type 2 diabetes, in a geographical area moderately affected by deprivation. No statistical relationship could be demonstrated between deprivation and HbA(1c). Deprived patients with diabetes presented with higher levels of fasting blood glucose, lower levels of LDL cholesterol and a significantly higher risk of obesity (P=0.0020). As for complications, microalbuminuria was linked to deprivation (P=0.03), but no associations with other complications were found. Quality of life was poorer for all physical, mental and social dimensions in deprived patients., Conclusion: In this diabetic population, deprivation and glycaemic control were not associated. However, more deprived subjects with diabetes were at higher risk of renal disease. A deprived state was related to an altered quality of life as assessed by the SF-36 score., (Copyright © 2011 Elsevier Masson SAS. All rights reserved.)

To determine the value of the admission 12-lead electrocardiogram to predict infarct size limitation by thrombolytic therapy, data were analyzed in 488 of 533 patients with acute myocardial infarction (AMI) from a randomized multicenter study. All patients had typical electrocardiographic changes diagnostic for an AMI and were admitted within 4 hours after the onset of chest pain; 245 patients were allocated to thrombolytic treatment and 243 to conventional treatment. Cumulative 72-hour release into plasma of myocardial alpha-hydroxybutyrate dehydrogenase (HBDH) was used as a measure of infarct size. In general, the amount of infarct limitation due to thrombolytic therapy was proportional to the size of the area at risk. Patients with new Q waves, high QRS score and high ST-segment elevation or depression had the largest enzymatic infarct size in both treatment groups, irrespective of location of the AMI. Compared with conventionally treated patients, patients with anterior AMI treated with streptokinase had significant infarct size limitation (480 U/liter HBDH, 37%), and limitation was most prominent in those with Q waves (820 U/liter HBDH) or high ST elevation (750 U/liter HBDH). Infarct size limitation in inferior AMI was less impressive (330 U/liter HBDH, 33%) and patients with high ST-segment elevation (460 U/liter HBDH) or marked contralateral ST-segment depression (430 U/liter HBDH) had the most notable infarct limitation.(ABSTRACT TRUNCATED AT 250 WORDS)

The effect of coronary artery recanalization on early and late right and left ventricular function was studied in patients with an acute inferior wall myocardial infarction caused by an occlusion of the right coronary artery. Fifty-four out of 138 patients, with chest pain lasting less than 4 hours, with ST elevations diagnostic for acute myocardial infarction not responding to medical treatment, and without contraindication for thrombolytic therapy, had an occluded right coronary artery. In 26 of these 54 patients, the occlusion was located proximal to the first right ventricular branch. Fourteen of them were treated conventionally (group A) and 12 with intracoronary streptokinase (group B). In 28 patients, the occlusion was distal to the first right ventricular branch. Fifteen were treated conventionally (group C) and 13 with intracoronary streptokinase (group D). In all patients, coronary angiograms were made 2 to 3 weeks after acute myocardial infarction. A nuclear angiogram was made the second day after admission and 3 months later to determine right and left ventricular ejection fraction. Values of radionuclide left and right ventricular ejection fraction (RVEF) between acute study (less than 48 hours after acute myocardial infarction [AMI]) and late study (3 months after AMI) showed no significant improvement in the four groups of patients studied. Group A patients (patients with total occlusion of the right coronary artery treated conventionally) had a significantly lower RVEF acutely and at late study as compared to the other three groups.(ABSTRACT TRUNCATED AT 250 WORDS)

The effect of left ventricular function on changes in plasma volume during acetate and bicarbonate dialysis was studied in stable, chronic dialysis patients. Preservation of plasma volume in patients with a normal left ventricular function (mean circumferential fibre shortening velocity (VcF) greater than or equal to 1 circ/s) was significantly less during the first hour of acetate dialysis than during bicarbonate dialysis. However, in patients with impaired left ventricular function (VcF less than 1 circ/s) the decrease in plasma volume was more pronounced during acetate when compared to bicarbonate dialysis. This resulted in a decreased ultrafiltration volume and haemodynamic instability in these patients during acetate dialysis. The fibre shortening velocity increased during acetate and bicarbonate dialysis in patients with a normal left ventricular function, whereas in patients with impaired left ventricular function fibre shortening velocity increased only during bicarbonate dialysis. In conclusion, in patients with an impaired left ventricular function, bicarbonate is preferable to acetate in chronic dialysis.

This study compares inducibility of ventricular tachyarrhythmias by programmed electrical stimulation of the heart in patients with myocardial infarction with and without reperfusion after streptokinase therapy. Sixty-two consecutive patients admitted with an acute myocardial infarction were randomized to either combined intravenous and intracoronary streptokinase (streptokinase group) or to standard coronary care unit treatment (control group). Thirty-six of the 62 patients (21 patients from the streptokinase and 15 from the control group) with a first myocardial infarction were studied by programmed ventricular stimulation after a mean of 26 +/- 14 days. No patient had a history of antiarrhythmic drug use or documentation of a ventricular arrhythmia before the initial admission. A sustained ventricular arrhythmia was induced in 10 (48%) of the 21 patients randomized to streptokinase therapy and in all 15 (100%) control patients (p less than 0.001). Sustained monomorphic ventricular tachycardia was induced in 6 (29%) and 10 (67%) patients, respectively (p less than 0.05). To terminate an induced arrhythmia, direct current countershock was required in 33% of patients in the streptokinase group and 73% of patients in the control group (p less than 0.02). Seventeen of the 21 patients treated with streptokinase and no control patient had evidence of early reperfusion 200 +/- 70 minutes after the onset of pain. In comparison with patients without early reperfusion, patients in the reperfused group had a lower maximal serum creatine kinase value (p less than 0.01), a shorter time to peak creatine kinase value (p less than 0.001) and a higher angiographic left ventricular ejection fraction (62 versus 45%, p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
