Telematic interview in telepharmacy: consensus document for farmacotherapeutic monitoring and informed drug delivery.

Telepharmacy is defined as the practice of remote pharmaceutical care, using information and communication technologies. Given its growing importance in outpatient pharmaceutical care, the Spanish Society of Hospital Pharmacy developed a consensus document, "Guía de entrevista telemática en atención farmacéutica," as part of its strategy for the development and expansion of telepharmacy, with key recommendations for effective pharmacotherapeutic monitoring and informed dispensing and delivery of medications through telematic interviews. The document was developed by a working group of hospital pharmacists with experience in the field. It highlights the benefits of telematic interviewing for patients, hospital pharmacy professionals, and the healthcare system as a whole, reviews the various tools for conducting telematic interviews, and provides recommendations for each phase of the interview. These recommendations cover aspects such as tool/platform selection, patient selection, obtaining authorization and consent, assessing technological skills, defining objectives and structure, scheduling appointments, reviewing medical records, and ensuring humane treatment. Telematic interview is a valuable complement to face-to-face consultations but its novelty requires a strategic and formal framework that this consensus document aims to cover. The use of appropriate communication tools and compliance with recommended procedures ensure patient safety and satisfaction. By implementing telematic interviews, healthcare institutions can improve patient care, optimize the use of resources and promote continuity of care.

Real-life experience after 3 months with tezepelumab before marketing approval / Experiencia de la vida real después de 3 meses con tezepelumab antes de la aprobación de comercialización

Background: Tezepelumab is a monoclonal antibody targeting thymic stromal lymphopoietin (TSLP), implicated in asthma pathogenesis, and that has been approved for patients with severe uncontrolled asthma in Spain in October 2023. This study evaluates our experience with Tezepelumab for those patients who received the indicated drug off-label prior to its commercialization. Methods: We conducted a real-life observational study on three patients from the Severe Asthma Unit of the Hospital Universitario de Fuenlabrada, Spain, who received Tezepelumab off-label before its official approval. We analyzed symptoms control based on ACT, exacerbations, reductions in the doses of oral corticosteroid, lung function, blood changes and safety at 3 months of treatment. Results: Tezepelumab demonstrated efficacy in improving asthma control and a notable reduction in emergency department visits. OCS use decreased, with one patient halving their prednisone dose. Lung function, particularly FEV1 and FEV1/FVC parameters, improved, but no significant changes were observed in FeNO levels, blood eosinophil counts and total IgE. The treatment exhibited a favorable safety profile with no reported adverse effects during the study period. Conclusions: In this preliminary real-world experience prior to the official approval of tezepelumab in Spain, this monoclonal antibody showed promising results and suggests its potential as a valuable alternative for the treatment of severe asthma.(AU)

Evolution of Antibiotic Resistance in Escherichia coli and Klebsiella pneumoniae from Urine Cultures.

OBJECTIVE: Determine the evolution of antibiotic resistance of symptomatic bacteriuria caused by Escherichia coli (E. coli) and Klebsiella pneumoniae (K. pneumoniae) in Granada. MATERIAL AND METHOD: A descriptive retrospective study was carried out, including antibiograms of urine cultures in which microorganisms identified as E. coli and K. pneumoniae, were isolated in the Microbiology laboratory of the Hospital Universitario Virgen de las Nieves (Granada, Spain) between January 2016 and June 2021. RESULTS: E. coli was the most frequent isolate (10,048) and its resistance to ampicillin (59.45%) and ticarcillin (59.59%), and the increase to cefepime (15.07%) and amoxicillin-clavulanic acid (17.67%) is noteworthy. K. pneumoniae (2222) is notable for resistance to Fosfomycin (27.91%) and an increase to ciprofloxacin (37.79%) and amoxicillin-clavulanic acid (36.63%). Resistance is generally higher in hospitalized patients, males, and adults. CONCLUSIONS: Antibiotic resistance to the studied Enterobacteriaceae is on the rise, requiring empirical treatment targeted to the population area.

Shigelosis atendidas en el servicio de urgencias de un hospital regional del sudeste de España: Desde su presencia a la multirresistencia / Shigellosis attended in the emergency department of a regional hospital in southeastern Spain: from their presence to multiresistance

Introduction. In the bacterial etiology of severe acute infectious diarrhea, except that caused by Clostridioides difficile, most of them have an invasive character and antibiotic treatment will be necessary in specific situations. Shigella is a classic pathogen, in which it is crucial to know the sensitivity to different classic and alternative antimicrobials. The objective of this work was to analyze the presence of shigellosis and the rate of antibiotic resistance.Methods. A descriptive-retrospective study of the reports of shigellosis of stool cultures issued between January 2016 and April 2022 was conducted.Results. A total of 34 episodes (16 -47.1%- by Shigella sonnei) were observed, as of 2018. There were only 2 pediatric cases. The overall resistance rate to azithromycin, trimethoprim-sulfamethoxazole and ciprofloxacin was 52.9%, 64.7% and 44.1%, respectively. 26.5% were resistant to the 3 groups of antibiotics. There was a higher rate of resistance for S. sonnei. The emergence of resistance to cephalosporins in recent years stands out. Episodes of multidrug-resistant shigellosis were detected between 2020 (1 by S. flexneri) and 2022 (4 by S. sonnei).Conclusions. The episodes of shigellosis are emerging in our environment with a higher rate of multi-resistance. In this context, current empirical treatments for acute enteroinvasive enteritis are at risk of failure, if necessary.

Introducción: En la etiología bacteriana de la diarrea infecciosa aguda grave, exceptuando la causada por Clostridioides difficile, la mayor parte presentan un carácter invasor y el tratamiento antibiótico será preciso en situaciones concretas. Shigella es un patógeno clásico, en el que es crucial conocer la sensibilidad a distintos antimicrobianos clásicos y alternativos. El objetivo de este trabajo fue analizar la presencia de shigelosis y la tasa de resistencia a los antibióticos. Métodos: Se realizó un estudio descriptivo-retrospectivo de los informes de shigelosis de los coprocultivos emitidos entre enero de 2016 y abril de 2022. Resultados: Se observó un total de 34 episodios (16-47,1%- por Shigella sonnei), a partir del 2018. Sólo hubo 2 casos pediátricos. La tasa de resistencia global a azitromicina, trimetoprim-sulfametoxazol y ciprofloxacino fue de 52,9%, 64,7% y 44,1%, respectivamente. El 26,5% fueron resistentes a los 3 grupos de antibióticos. Hubo mayor tasa de resistencia por S. sonnei. Destaca la aparición de resistencia a cefalosporinas en los últimos años. Los episodios de shigelosis multirresistente se detectaron entre 2020 (1 por S. flexneri) y 2022 (4 por S. sonnei). Conclusiones: Los episodios de shigelosis importada están emergiendo en nuestro medio con una mayor tasa de multirresistencia. En este contexto, los tratamientos empíricos actuales para las enteritis agudas enteroinvasivas corren el riesgo de fracasar, en caso de ser necesarios. (AU)

Sex differences in cardiovascular and disease-related features in axial spondyloarthritis. A multicenter study of 912 patients.

OBJECTIVES: To determine the potential impact of sex-specific disease-related characteristics on cardiovascular (CV) disease in axial spondyloarthritis (axSpA). METHODS: Cross-sectional study of the Spanish AtheSpAin cohort to study CV disease in axSpA. Data on carotid ultrasound and CV disease and disease-related features were collected. RESULTS: 611 men and 301 women were recruited. Classic CV risk factors were significantly less prevalent in women, who also showed a lower frequency of carotid plaques (p = 0.001), lower carotid intima-media thickness (IMT) values ​​(p<0.001) and CV events (p = 0.008). However, after adjustment for classic CV risk factors, only the differences with respect to carotid IMT remained statistically significant. Women showed higher ESR at diagnosis (p = 0.038), and more active disease (ASDAS, p = 0.012, and BASDAI, p<0.001). They had shorter disease duration (p<0.001), lower prevalence of psoriasis (p = 0.008), less structural damage (mSASSS, p<0.001), and less mobility limitation (BASMI, p = 0.033). To establish whether these findings could lead to sex differences in CV disease burden, we compared the prevalence of carotid plaques in men and women with the same level of CV risk stratified according to the Systematic Coronary Risk Evaluation (SCORE). Men included in the low-moderate CV risk SCORE category had more carotid plaques (p = 0.050), along with longer disease duration (p = 0.004), higher mSASSS (p = 0.001) and psoriasis (p = 0.023). In contrast, in the high-very high-risk SCORE category, carotid plaques were observed more frequently in women (p = 0.028), who were characterized as having worse BASFI (p = 0.011), BASDAI (p<0.001) and ASDAS (p = 0.027). CONCLUSION: Disease-related features may influence the expression of atherosclerosis in patients with axSpA. This may be especially applicable to women at high CV risk, characterized by greater disease severity and more severe subclinical atherosclerosis than men, suggesting a stronger interaction between disease activity and atherosclerosis in women with axSpA.

Cardiovascular and disease-related features associated with extra-articular manifestations in axial spondyloarthritis. A multicenter study of 888 patients.

OBJECTIVES: To determine the potential impact of extra-articular manifestations (EAMs) on disease characteristics and cardiovascular (CV) risk in patients with axial spondylarthritis (axSpA). METHODS: This is a cross-sectional study from the AtheSpAin cohort, a Spanish multicenter cohort to study atherosclerosis in axSpA. Data on the history of CV events, subclinical carotid atherosclerosis, and disease-related features, including EAMs, were collected. RESULTS: 888 axSpA patients were recruited. Concomitant acute anterior uveitis (AAU), psoriasis (PSO), and inflammatory bowel disease (IBD) were present in 177 (19.9%), 96 (10.8%), and 57 (6.4%) patients, respectively. When compared with axSpA patients without EAMs, a significant increase in past CV events was observed in patients with PSO (9% versus 4%, p = 0.048) and in those with at least one EAM (7% versus 4%, p = 0.032) or with more than one EAM (11% versus 4%, p = 0.022). The frequency of carotid plaques and the values of cIMT were higher in patients with EAMs than in those without EAMs, although only the univariable analysis for carotid plaques in patients with PSO (39% versus 30%, p = 0.038) and for cIMT in patients with AAU (665 ± 156 µm versus 637 ± 139 µm, p = 0.042) and those with at least one EAM (661 ± 155 µm versus 637 ± 139 µm, p = 0.024) showed significant results. In addition, patients with PSO or IBD were found to have specific disease-related features, such as higher ESR at diagnosis, and more frequent use of glucocorticoids and TNF inhibitors than those without EAMs. Also, PSO patients had more commonly peripheral involvement and those with AAU more severe radiographic damage than those without EAMs. The frequency of HLA B27 was higher in patients with AAU and lower in those with PSO or IBD compared to those without EAMs. CONCLUSION: Patients with axSpA and EAMs, in addition to displaying their own disease-related features, are likely to have an increased CV risk that appears proportional to the number of EAMs and could be related to proatherogenic factors other than traditional CV risk factors, such as the inflammatory load and the use of glucocorticoids.

Irisin as a Novel Biomarker of Subclinical Atherosclerosis, Cardiovascular Risk and Severe Disease in Axial Spondyloarthritis.

Introduction: Patients with axial spondyloarthritis (axSpA) have a high disease burden mainly due to the rheumatic disease itself, and also exhibit accelerated atherosclerosis, that leads to a higher incidence of cardiovascular (CV) disease. Accordingly, the identification of biomarkers of CV risk and inflammation in axSpA patients is clinically relevant. In this sense, given the beneficial functions exerted by the adipomyokine irisin in processes related to CV disease and inflammation, our aim was to assess, for the first time, the role of irisin as a genetic and serological biomarker of subclinical atherosclerosis, CV risk and disease severity in axSpA patients. Methods: A large cohort of 725 Spanish patients with axSpA was included. Subclinical atherosclerosis (presence of plaques and abnormal carotid intima-media thickness values) was evaluated by carotid ultrasound. Four irisin polymorphisms (rs16835198 G/T, rs3480 A/G, rs726344 G/A, and rs1570569 G/T) were genotyped by TaqMan probes. Additionally, serum irisin levels were determined by ELISA. Results: Low irisin levels were linked to the presence of plaques (p=0.002) and atherogenic index values ≥4 (p=0.01). Serum irisin were positively correlated with C-peptide levels (p<0.001) and negatively correlated with visual analogue scale and Bath Ankylosing Spondylitis Metrology Index (p<0.05 in all the cases). Moreover, lower irisin levels were observed in patients with sacroiliitis and in those with a negative HLA-B27 status (p<0.001 and p=0.006, respectively), as well as in those treated with non-steroidal anti-inflammatory drugs and conventional disease-modifying antirheumatic drugs (p<0.001 and p=0.002, respectively). Interestingly, the TT genotype and the T allele of rs16835198 were less frequent in axSpA patients with ASDAS >2.1 (Odds Ratio (OR): 0.48 [0.28-0.83] and OR: 0.73 [0.57-0.92], respectively, p=0.01 in both cases). Additionally, the frequency of rs1570569 T allele was higher in these patients (OR: 1.46 [1.08-1.97], p=0.01). Furthermore, the GGGT haplotype was more frequent in patients with ASDAS values >2.1 (OR: 1.73 [1.13-2.66], p=0.01). Conclusions: Our results indicate that low serum irisin levels could be indicators of the presence of subclinical atherosclerosis, high CV risk and more severe disease in axSpA patients. In addition, irisin may also constitute a genetic biomarker of disease activity in axSpA.

Factors associated with atherosclerosis in radiographic and non-radiographic axial spondyloarthritis. A multicenter study on 838 patients.

OBJECTIVES: To identify disease-related factors associated with subclinical atherosclerosis and cardiovascular (CV) events in a large series of patients with axial spondyloarthritis (axSpA) and to identify possible differences in the effect of the potential pro-atherogenic factors between ankylosing spondylitis (AS) non-radiographic axSpA (nr-axSpA). METHODS: This is a cross-sectional observational study of the AtheSpAin cohort, a Spanish multicenter cohort to study atherosclerosis in axSpA. Subclinical atherosclerosis determined by carotid ultrasound included assessment of carotid intima-media thickness (cIMT) and plaque detection. RESULTS: 639 AS and 167 nr-axSpA patients were recruited. CV risk factors (CRF) and several disease-related factors showed a statistically significant association with subclinical atherosclerosis in the crude analysis. After adjustment for age, sex, and smoking (model 1), associations remained statistically significant for spinal mobility, inflammatory bowel disease, use of prednisone, and Disease-modifying antirheumatic drugs (DMARD) when assessing carotid plaques and for acute phase reactants (APR) at diagnosis, use of prednisone, DMARD, and TNF-inhibitors when measuring cIMT. In model 2, which also included classic CRF as confounding factors to identify axSpA features with a potential independent pro-atherogenic effect, the functional status was the only variable significantly associated with plaques and the use of prednisone and APR at diagnosis with cIMT. No association differences were found between both subtypes of patients. Besides, APR at diagnosis were also associated with subsequent development of CV events that had occurred in 33 patients. CONCLUSION: Apart from CRF, atherosclerotic disease in AxSpA is associated with disease-related factors such as inflammatory response and disease severity, with no differences between AS and nr-axSpA.

Combining Serial and Parallel Functionality in Functional Lung Avoidance Radiation Therapy.

PURPOSE: Functional lung avoidance (FLA) radiation therapy (RT) aims to minimize post-RT pulmonary toxicity by preferentially avoiding dose to high-functioning lung (HFL) regions. A common limitation is that FLA approaches do not consider the conducting architecture for gas exchange. We previously proposed the functionally weighted airway sparing (FWAS) method to spare airways connected to HFL regions, showing that it is possible to substantially reduce risk of radiation-induced airway injury. Here, we compare the performance of FLA and FWAS and propose a novel method combining both approaches. METHODS: We used breath-hold computed tomography (BHCT) and simulation 4-dimensional computed tomography (4DCT) from 12 lung stereotactic ablative radiation therapy patients. Four planning strategies were examined: (1) Conventional: no sparing other than clinical dose-volume constraints; (2) FLA: using a 4DCT-based ventilation map to delineate the HFL, plans were optimized to reduce mean dose and V13.50 in HFL; (3) FWAS: we autosegemented 11 to 13 generations of individual airways from each patient's BHCT and assigned priorities based on the relative contribution of each airway to total ventilation. We used these priorities in the optimization along with airway dose constraints, estimated as a function of airway diameter and 5% probability of collapse; and (4) FLA + FWAS: we combined information from the 2 strategies. We prioritized clinical dose constraints for organs at risk and planning target volume in all plans. We performed the evaluation in terms of ventilation preservation accounting for radiation-induced damage to both lung parenchyma and airways. RESULTS: We observed average ventilation preservation for FLA, FWAS, and FLA + FWAS as 3%, 8.5%, and 14.5% higher, respectively, than for Conventional plans for patients with ventilation preservation in Conventional plans <90%. Generalized estimated equations showed that all improvements were statistically significant (P ≤ .036). We observed no clinically relevant improvements in outcomes of the sparing techniques in patients with ventilation preservation in Conventional plans ≥90%. CONCLUSIONS: These initial results suggest that it is crucial to consider the parallel and the serial nature of the lung to improve post-radiation therapy lung function and, consequently, quality of life for patients.

HLA Class II Polymorphism and Humoral Immunity Induced by the SARS-CoV-2 mRNA-1273 Vaccine.

The vaccines designed against the SARS-CoV-2 coronavirus are based on the spike (S) protein. Processing of the S protein by antigen-presenting cells (APC) and its subsequent presentation to T cells is an essential part of the development of a humoral response. HLA-class II alleles are considered immune response genes because their codified molecules, expressed on the surface of APCs (macrophages, dendritic, and B cells) present antigenic peptides to T cell via their T cell receptor (TCR). The HLA-class II genes are highly polymorphic, regulating what specific peptides induce follicular helper T cells (TFH) and promote B lymphocyte differentiation into plasma or memory B cells. This work hypothesizes that the presence of certain HLA-class II alleles could be associated with the intensity of the humoral response (amount, length) to the SARS-CoV2 mRNA 1273 vaccine. We have studied the relationship between the HLA-class II typing of 87 health workers and the level of antibodies produced 30 days after vaccination. We show a possible association between the HLA-DRB1* 07:01 allele and the HLA-DRB1*07:01~DQA1*02:01~DQB1*02:02 haplotype to a higher production of antibodies 30 days after the administration of the second dose of mRNA-1273.

Study of humoral and cellular immunity in vaccinated with mRNA-1273.

The new vaccines against SARS-CoV-2 have raised a lot of expectations about their ability to induce immunity and the duration of this. This is the case of mRNA vaccines such as Moderna's mRNA-1273. Therefore, it is necessary to study the humoral and cellular immunity generated by these vaccines. Our objectives are determining what is the normal response of antibody production, and what is the level of protective antibodies and monitoring patients in case of subsequent infection with COVID-19. We present the first results of a longitudinal study of the humoral response in 601 health workers vaccinated with Moderna. The results show a humoral immunity at 90 days after the second dose of 100%, with a strong decrease between the levels of circulating anti-S IgG antibodies between days 30 and 90 post-vaccination. Observing a steeper decline in those who had higher titles at the beginning. In addition, we present a cellular response of 86% at three months after the second dose, which is related to low humoral response.

Comparative evaluation of chemiluminescent immunoassay and enzyme-linked immunosorbent assays for the diagnosis of West Nile virus infections.

In August 2020, anew West Nile virus (WNV) outbreak affected 71 people with meningoencephalitis in Andalusia (Spain). Samples from these individuals were received in our laboratory, a regional Virus Referral Centre. The aim of this study was to compare the agreement, sensitivity and specificity of findings between the WNV VIRCLIA IgG and IgM assay (Vircell, Spain) and the WNV ELISA IgM and IgG assay (Euroimmun, Germany) and to compare the performance of WNV VIRCLIA IgM and Euroimmun ELISA for cerebrospinal fluid (CSF) diagnosis. The study included 24 CSF samples (paired with serum samples) and 247 serum samples from 217 patients with suspected WNV infection (1 or 2 per patient). The agreement between ELISA and CLIA tests for IgM and Ig G detection in serum was 93% (kappa index = 0.85) and 96% (kappa index = 0.89) respectively. Sensitivity values of ELISA and CLIA tests for IgM in serum samples were 96.7% and 98.9%, respectively, and specificity values were 96.4% and 95.4% respectively. Sensitivity values of ELISA and CLIA test for IgG in serum samples were 91.1% and 97%, respectively, and specificity values were 100% and 98.8% respectively. Results obtained with ELISA and CLIA tests in CSF samples showed 75% agreement between them (kappa index = 0.51). According to these findings, the WNV VIRCLIA IgM and IgG monotest offers an accurate qualitative detection of WNV in serum and CSF specimens.

[Surveillance of rare diseases in Spain: Spanish Registry of Rare Diseases (ReeR).] / Vigilancia de las enfermedades raras en España: el Registro Estatal de Enfermedades Raras (ReeR).

Traditionally, epidemiological surveillance has focused on infectious diseases, but the concept of Public Health surveillance, introduced in Spain with the Law 33/2011, is broader and includes chronic diseases. Health strategies for these diseases need epidemiological information to improve understanding of socio-health needs and to facilitate the efficient management of resources. The European Union defines rare diseases (RD) as those that, being life-threatening or chronically debilitating, have a prevalence of less than 5 cases per 10,000 inhabitants. The RD Strategy of the National Health System, approved in 2009 and updated in 2014, recommends the development of regional registries of rare diseases (RAER), in addition to a national registry. The REpIER and Spain-RDR projects of the Institute of Health Carlos III (ISCIII) promoted the creation and regulation of 94% of the RAER. After more than 10 years of initiatives and work to improve the knowledge of RD's epidemiology in Spain, it was possible to implement the Spanish Registry of Rare Diseases (ReeR) in 2015, becoming one of the first population surveillance systems for chronic diseases of state scope. The ReeR procedures manual is the result of consensus between the RAER, the Ministry of Health, the ISCIII and the patient associations. The participatory methodology used for the implementation and launching of ReeR is considered an added value. The information system implemented will allow improving knowledge about the prevalence and distribution of RD in Spain.

Tradicionalmente la vigilancia epidemiológica se ha centrado en enfermedades transmisibles, pero el concepto de vigilancia en Salud Pública, incorporado en España con la Ley 33/2011, es más amplio e incluye las enfermedades crónicas. Las estrategias de salud para estas enfermedades necesitan disponer de información epidemiológica para mejorar el conocimiento de las necesidades sociosanitarias y facilitar la gestión eficiente de recursos. La Unión Europea define las enfermedades raras (ER) como aquellas que, con peligro de muerte o invalidez crónica, presentan una prevalencia inferior a 5 casos por cada 10.000 habitantes. La Estrategia en ER del Sistema Nacional de Salud, aprobada en 2009 y actualizada en 2014, recomienda desarrollar registros autonómicos de enfermedades raras (RAER) y uno estatal. Los proyectos REpIER y Spain-RDR del Instituto de Salud Carlos III (ISCIII) impulsaron la creación y regulación del 94% de los RAER; y tras más de 10 años de iniciativas y trabajos para mejorar el conocimiento de la epidemiología de las ER en España, se logró implementar el Registro Estatal de Enfermedades Raras (ReeR) en 2015, convirtiéndose en uno de los primeros sistemas de vigilancia poblacional de enfermedades crónicas de ámbito estatal. El manual de procedimientos del ReeR es el resultado del consenso entre los RAER, Ministerio de Sanidad, ISCIII y asociaciones de pacientes. La metodología participativa empleada para la implementación y puesta en funcionamiento del ReeR es considerada un valor añadido. El sistema de información implementado va a permitir mejorar el conocimiento sobre la prevalencia y distribución de las ER en España.

Potential relation of cardiovascular risk factors to disease activity in patients with axial spondyloarthritis.

BACKGROUND: Axial spondyloarthritis (axSpA) patients are known to have a higher prevalence of several comorbidities, including, among others, an increased risk of atherosclerosis, hypertension, dyslipidemia, and diabetes. The purpose of the present study was to determine whether the sum of traditional cardiovascular (CV) risk factors is related to disease characteristics, such as disease activity, in patients with axSpA. METHODS: A cross-sectional study that encompassed 804 patients with axSpA was conducted. Patients were assessed for the presence of five traditional CV risk factors (diabetes mellitus, dyslipidemia, hypertension, obesity, and smoking status), and disease activity measurements. A multivariable regression analysis was performed to evaluate whether the number of classic CV risk factors was independently associated with specific features of the disease, to include disease activity. RESULTS: A multivariable analysis showed that Ankylosing Spondylitis Disease Activity Score-C reactive protein (ASDAS-CRP) activity score was significantly higher in patients with 1 [beta coefficient 0.3 (95% confidence interval (CI) 0.1-0.5), p = 0.001] and ⩾2 [beta coefficient 0.5 (95% CI 0.3-0.7), p = 0.000] CV risk factors compared with those without CV risk factors. Similarly, patients with 1 [OR 2.00 (95%CI 0.99-4.02), p = 0.053] and ⩾2 [OR 3.39 (95%CI 1.82-6.31), p = 0.000] CV risk factors had a higher odds ratio for the presence of high disease activity compared with the zero CV category. The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) activity score was significantly associated with the number of CV risk factors, being higher in patients with more CV risk factors. These relationships showed a CV risk factor-dependent effect being beta coefficients and ORs higher for the effect of ⩾2 over 1 CV risk factor. CONCLUSION: Among patients with axSpA, as the number of traditional CV risk factors increased, disease activity similarly increases in an independent manner.

Vaspin in atherosclerotic disease and cardiovascular risk in axial spondyloarthritis: a genetic and serological study.

BACKGROUND: Vaspin is a novel anti-inflammatory adipokine associated with cardiovascular (CV) disease and inflammation in chronic inflammatory conditions different from axial spondyloarthritis (axSpA). Given the high incidence of CV disease (mainly due to accelerated atherosclerosis) exhibited by axSpA patients, we wondered if vaspin could also be a key molecule in this process. However, data on the role of vaspin regarding atherosclerotic disease in the context of axSpA is scarce. For this reason, we aimed to evaluate the implication of vaspin, at the genetic and serological level, in subclinical atherosclerosis and CV risk in axSpA. METHODS: This study included 510 patients diagnosed with axSpA. Carotid ultrasound (US) was performed to evaluate the presence of subclinical atherosclerosis. Three vaspin gene variants (rs2236242, rs7159023, and rs35262691) were genotyped by TaqMan probes. Serum vaspin levels were assessed by enzyme-linked immunosorbent assay. Statistical analysis was performed using STATA® v.11.1. RESULTS: Serum vaspin levels were significantly higher in female patients than in males and also in obese patients when compared to those with normal weight (p < 0.05). At the genetic level, we disclosed that the minor allele of rs2236242 (A) was associated with lower serum vaspin levels in axSpA, while the rs7159023 minor allele (A) was linked to higher serum levels (p < 0.05). When the three polymorphisms assessed were combined conforming haplotypes, we disclosed that the TGC haplotype related to high serum levels of vaspin (p = 0.01). However, no statistically significant association was observed between vaspin and markers of subclinical atherosclerosis, both at the genetic and serological level. CONCLUSIONS: Our results revealed that vaspin is linked to CV risk factors that may influence on the atherosclerotic process in axSpA. Additionally, we disclosed that serum vaspin concentration is genetically modulated in a large cohort of patients with axSpA.

First case of abdominal infection caused by bacteroides fluxus.

Bacteroides fluxus is a Gram-negative anaerobic bacillus isolated from human faeces in healthy individuals. Until now, this bacterium had not been involved in human diseases. We report the first case of abdominal infection due to this microorganism in an elderly patient. A 76-year-old man with a history of chronic pulmonary obstructive disease presented with dyspnea, orthopnea and cough. The clinical evolution worsened with both a colonic ischemia and further diffuse peritonitis of pancreatic origin. Peritoneal fluid was obtained and the culture yielded B. fluxus in pure culture. Resistance to penicillin, amoxicillin-clavulanate, clindamycin and moxifloxacin was documented. Treatment with meropenem + linezolid was started, but the patient finally died due to a multiorganic failure.
