RESUMO

Spanish Autonomous Communities (ACs) are entitled to decide on the prescription requirements of their own territories, which can create inequalities in access to new drugs in the management of psoriasis. The objective of this study was to assess whether the level of restrictions in the access to new drugs for the management psoriasis was associated with the probability of achieving disease control measured using the Minimum Disease Activity (MDA) criteria. Therefore, we combined the results of 2 previous independent, cross-sectional studies: one that described the MDA in psoriasis by AC, and another that evaluated the level of restrictions to drug access by AC. We found that the higher the number of restrictions the lower the chances of achieving the MDA criteria (p = 0.013). Our results suggest that, in Spain, geographical differences in the access to new drugs may be creating health inequalities across the country.

RESUMO

OBJECTIVES: To evaluate the treatment modalities and their effects in primary Sjögren's syndrome (pSS) patients with interstitial lung disease (ILD). METHODS: In this chart review study, patients diagnosed with pSS-related ILD (pSS-ILD) between January 2004 and August 2022 were screened. Glucocorticoid use and administered disease-modifying antirheumatic drugs (DMARDs) were determined. The difference between forced vital capacity (FVC) and diffusion capacity of the lungs for carbon monoxide (DLCO) before and after treatment was evaluated. RESULTS: ILD was present in 44 of 609 patients (7.2%) diagnosed with pSS. In 27 patients included in the study, steroid usage was 81.5%. There was a statistically insignificant increase in FVC% (from 80.20±22.1 to 81.6±23.0) and a decrease in DLCO% (53.7±15.3-52.2±19.3) with DMARD treatment (p=0.434 and p=0.652, respectively). There was no significant difference between the treatment groups (azathioprine [AZA], mycophenolate mofetil [MMF], and rituximab [RTX]) in terms of the change in FVC% and DLCO% compared with baseline levels. The effect of treatment on FVC and DLCO was similar in UIP and NSIP patterns. CONCLUSIONS: AZA, MMF, and RTX have similar effects on pulmonary functions in pSS-ILD and provide disease stabilization.

RESUMO

Drugs do not disappear once they have been excreted. In fact, 992 active principles have already been measured in the different environmental matrices. A recent study led by scientists from the University of York has studied the presence of drugs in the rivers of more than 100 different countries, showing that environmental contamination by pharmaceuticals is a global issue and that, concentrations found are frequently harmful to the environment. In this work, we have tried to briefly expose the problem of environmental contamination with medicines, but above all, we have tried to address the possible solutions, with a perspective from the field of hospital pharmacy. This is a very complex matter (a wicked problem), since it involves multiple stakeholders with different visions and interests regarding medicines. In order to find solutions, we will probably need to act at all steps of the drug's life cycle. Until now, health professionals have been part of the problem. It is time for us to be part of the solution.

RESUMO

INTRODUCTION: Biological disease-modifying antirheumatic drugs (bDMARD) have improved the clinical course and quality of life of patients with rheumatoid arthritis (RA). However, some patients failed to respond or have an insufficient response to bDMARD early in the course of the treatment. OBJECTIVES: To determine the percentage of RA patients who need to switch due to ineffectiveness in the first year of treatment and to identify specific baseline features as possible predictors of switch due to ineffectiveness in the first year of treatment. MATERIALS AND METHODS: An observational retrospective study was conducted with patients with RA that started their first bDMARD. Demographic data, disease characteristics, disease activity data scores, laboratory parameters and treatment at baseline were collected. The proportion of patients who failed to respond and who switched to another bDMARD in the first year of treatment was calculated. RESULTS: A total of 437 (364 females, 83.3%) patients with RA were included. The majority of these patients started an anti-TNF-α agent (n=315, 72.1%). Forty-eight (11.0%) patients failed to respond to the bDMARD in the first year of treatment. There were significantly more current or former smokers (p=0.030), with a history of depression (p=0.003) and positive for RF at baseline (p=0.014) in the switch group. In the multivariate analysis, anti-TNF-α agents use (OR 8.3, 95% CI 2.4-28.8, p=0.001), tobacco exposure (OR 2.3, 95% CI 1.1-4.8, p=0.02) and history of depression (OR 3.1, 95% CI 1.3-7.7) seem to predict the need to switch in the first year of treatment due to ineffectiveness. DISCUSSION AND CONCLUSION: In our study, tobacco exposure and depression appear to be modifiable risk factors associated with early switching due to ineffectiveness. Addressing these factors in daily clinical practice is crucial to enhance the overall response to therapy and improve the well-being of patients.

RESUMO

BACKGROUND AND AIMS: The criteria for the use of proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) more restrictive than those approved were established in Catalonia by the Health System (CatSalut) to improve their efficiency, with different LDL-C values from which to start treatment according to risk factors. The aim of the study is to analyse adherence to these criteria and results. METHODS: A retrospective study of patients treated with PCSK9i at Vall d'Hebron University Hospital between 2016 and 2021 was performed using data from the Registry of Patients and Treatments and medical records. The degree of agreement with the CatSalut criteria, LDL-C-responders (decrease ≥30%), cardiovascular events and discontinuations were analysed. RESULTS: A total of 193 patients treated with PCSK9i were followed for a median of 27 months (IQR 23). The median age was 61 (IQR 15); 62.7% were men. Seventy percent of the patients had non-familial hypercholesterolemia. Treatment was for secondary prevention of cardiovascular disease in 82.4% of cases. The median LDL-C decreased from 139 (IQR 52) to 59 (IQR 45) mg/dL. The percentage of LDL-C reduction was 61.0% (IQR 30). In 72.5% of patients, all CatSalut criteria for starting treatment were met. The rate of responders was 85.4%. During follow-up, 19 patients (9.8%) had a cardiovascular event, and 15 (7.7%) discontinued treatment, in two cases due to toxicity. CONCLUSION: PCSK9i were used according to CatSalut criteria in three out of four cases. In this high-risk population, incidence of cardiovascular events was similar to that in clinical trials.

RESUMO

PURPOSE: To review and analyse the available literature on peripheral administration of noradrenaline (NA) with the aim of providing recommendations to ensure correct use and patient safety. METHODS: Systematic review on the databases PubMed, ISI Web of Science, SCOPUS, and Science Direct, using the following search terms: ("Noradrenaline" [Mesh]) AND ("Norepinephrine" [Mesh]) AND ("Vasopressors" [Mesh]) AND ("Peripheral infusions" [Mesh]) OR ("Extravasations" [Mesh]). A total of 1040 articles were identified. Animal studies and studies written in languages other than English were excluded. Finally, 83 articles were included. RESULTS: NA can be administered peripherally. The risk of extravasation should be taken into account, with phentolamine being the first pharmacological line of treatment. It has also been related to the appearance of thrombophlebitis, cellulitis, tissue necrosis, limb ischaemia, and gangrene, although its incidence seems to be low. The use of peripheral NA in children seems to be carried out without obvious complications. The use of standard concentrations is suggested to reduce the risk of errors. It is recommended to use 0.9% saline as the default diluent for peripheral NA. CONCLUSIONS: Peripheral infusions of NA could be a safe and beneficial option in early resuscitation provided that a number of guidelines are followed that reduce the likelihood of complications associated with this route.

RESUMO

Introducción: el hecho de que una persona no puede acceder a un servicio de salud puede favorecer la automedicación, que es la administración de fármacos según la autopercepción del individuo sobre su posible diagnóstico y solución. Aunque es una situación considerada como problema de salud pública, por medio de la educación o futuras investigaciones que generen propuestas, se podrá erradicar las barreras al acceso de la salud oral. Objetivo: determinar la prevalencia de la automedicación en odontología en adultos de Macas, Ecuador, durante el año 2021. Material y métodos: estudio descriptivo, cuantitativo, documental, comunicacional y transversal actual, donde se trabajó sobre la población de edad adulta de Macas, Ecuador; los datos se recolectaron mediante una encuesta online, para luego ser analizados en prevalencia, frecuencia y chi cuadrado. Resultados: 49% de los encuestados respondió que se automedican, los analgésicos fueron el tipo de medicamento más consumido (44.2%); 27% de los individuos respondió que el dolor dental era una causa para tomar medicamentos sin receta, el principal motivo para automedicarse y no acudir al odontólogo fue por indicación del técnico de farmacia (26%). Conclusiones: los datos epidemiológicos obtenidos en esta investigación demuestran la marcada tendencia de las personas a consumir medicinas sin receta médica, por lo que, se deduce que existe una barrera para acceder a los servicios de salud oral; por ello, debería darse la importancia y atención oportuna (AU)


Introduction: the fact that a person cannot access a health service, may favor self-medication, which is the administration of drugs according to the individual's self-perception about their possible diagnosis and solution. Although, it is a situation considered as a public health problem, through education or future research that generates proposals, it will be possible to eradicate the barriers to oral health access. Objective: to determine the prevalence of self-medication in dentistry in adults in Macas, Ecuador, during the year 2021. Material and methods: a descriptive, quantitative, documentary, communicational and current cross-sectional study was carried out on the adult population of Macas, Ecuador; data were collected by means of an online survey and then analyzed in terms of prevalence, frequency and chi-square. Results: 49% of those surveyed responded that they self-medicate, analgesics were the most consumed type of medicine (44.2%), 27% of the individuals responded that dental pain was a cause for taking medicines without prescription, the main reason for self-medicating and not going to the dentist was because of the indication of the pharmacy technician (26%). Conclusions: the epidemiological data obtained in this investigation show us the marked tendency of people to take medicines without a medical prescription; therefore, it can be deduced that there is a barrier to accessing oral health services, and for this reason it should be given importance and timely attention (AU)

RESUMO

Even though a large number of antihypertensive drugs are suitable for hypertension treatment, some new therapeutic targets are recently under development. Most are focused in the treatment of resistant hypertension, added to the drugs currently available for treating such condition. Others have specific particularities in their duration of action, which allows their use once per month or every six months and could become alternatives to the current antihypertensive treatment. Most interesting therapeutic targets are the renin-angiotensin-aldosterone system, through interference with the RNA of the angiotensinogen, the inhibition of brain aminopeptidase III, the inhibition of aldosterone synthase, and new non-steroidal aldosterone receptor antagonists. In addition, dual endothelin receptor antagonists or agonists of the NPR1 receptor, the main effector of natriuretic peptides are other new interesting therapeutic possibilities. In this paper, we review clinical data on the development of the most interesting molecules acting through these new therapeutic targets.

RESUMO

Diuretics have been used for decades in the treatment of hypertension. Its efficacy has been demonstrated in numerous clinical trials. It is well known that the reduction in cardiovascular risk is a consequence of the reduction in blood pressure levels regardless of the drug used, but thiazide diuretics continue to be first-line drugs, especially in low doses and combined with other drugs. The debate on the advantages of using chlorthalidone or hydrochlorothiazide continues, however hydrochlorothiazide is drug most used and for which there is greater availability. The association with potassium-sparing diuretics increases the effectiveness and reduces the adverse reactions of thiazides. A new group of drugs, close to potassium-sparing diuretics, that antagonise aldosterone synthase are showing promising results as antihypertensives. There are no significant differences between men and women regarding the antihypertensive effect of thiazide diuretics.

RESUMO

La degeneración macular asociada a la edad (DMAE) constituye una de las principales causas de la pérdida de agudeza visual (AV) en los mayores de 50 años en el mundo, siendo la DMAE neovascular (DMAEn) la causante del 80% de los casos de pérdida de visión severa debido a esta enfermedad. Hace ya más de una década que se emplean los fármacos antifactor de crecimiento del endotelio vascular (anti-VEGF) para el tratamiento de esta enfermedad, cambiando drásticamente el pronóstico visual de estos pacientes. Sin embargo, los primeros estudios de los que se disponían datos de los resultados eran a corto plazo. En la actualidad existen ya diferentes series publicadas de los resultados de la DMAE a largo plazo tras el tratamiento con anti-VEGF, siendo el objetivo de la presente revisión sintetizar dichos resultados. El seguimiento medio de los estudios incluidos fue de 8,2 años (rango: 5-12 años). La AV inicial media fue 55,3 letras del Early Treatment Diabetic Retinopathy Study (ETDRS) (rango: 45,6-65) siendo la AV final media 50,1 letras (rango: 33,0-64,3), existiendo una pérdida media de 5,2 letras. Al final del seguimiento un 29,4% de los pacientes mantuvieron una AV>70 letras. El 67,9% de los pacientes se mantuvo estable al final del seguimiento (<15 letras de pérdida), existiendo una pérdida severa (≥15 letras) del 30,1%. La fibrosis y la atrofia fueron las principales causas de pérdida de AV a largo plazo, presentándose al final del seguimiento en un 52,5% y un 60,5%, respectivamente.(AU)


Age-related macular degeneration (AMD) is one of the main causes of visual acuity (VA) loss in people over 50 years of age worldwide, with neovascular AMD (nAMD) accounting for 80% of cases of severe vision loss due to this disease. Anti-vascular endothelial growth factor (anti-VEGF) drugs have been used for the treatment of this disease for more than a decade, changing drastically the visual prognosis of these patients. However, initial studies reporting data on outcomes were short term. Currently, there are different series published on the long-term results of AMD after treatment with anti-VEGF, and the aim of this review is to synthesize these results. The mean follow-up of the included studies was 8.2 years (range 5-12 years). The mean initial VA was 55.3 letters in the Early Treatment Diabetic Retinopathy Study (ETDRS) (range 45.6-65) and the mean final VA was 50.1 letters (range 33.0-64.3), with a mean loss of 5.2 letters. At the end of follow-up, 29.4% of the patients maintained a VA>70 letters. The 67.9% of patients remained stable at the end of follow-up (<15 letter loss), with a severe loss (≥15 letters) of 30.1%. Fibrosis and atrophy were the main causes of long-term VA loss, occurring at the end of follow-up in 52.5% and 60.5%, respectively.(AU)

RESUMO

BACKGROUND: Adalimumab biosimilar MSB11022 (Idacio ®) has been approved for the same indications as its originator (Humira ®), based on findings from clinical trials in plaque psoriasis. Data on its efficacy and safety in inflammatory bowel disease, however, are scarce. METHODS: Retrospective, observational study of 44 patients with inflammatory bowel disease: 30 were treated with originator adalimumab, 5 were directly started on MSB11022, and 9 switched from originator to biosimilar adalimumab. To evaluate the effectiveness of the use of adalimumab in inflammatory bowel disease, both laboratory markers (fecal calprotectin and C-reactive protein) and scales that measure the activity of inflammatory bowel disease using specific scales (Harvey-Bradshaw Index (HBI) have been usEd.) for Crohn's disease and Mayo Score for Ulcerative Colitis. Efficacy was evaluated by recording the adverse effects that could occur with the administration of adalimumab (original or biosimilar). The success of the switch was determined by analyzing meaningful differences in effectiveness and safety criteria. Concomitant therapy and the need for dose intensification were also analyzed. Objective of this study was to assess the effectiveness and safety of biosimilar adalimumab in adalimumab-naïve patients and patients switched from originator adalimumab. RESULTS: No significant differences were observed in clinical disease activity (P=.317) or biochemical parameters [fecal calprotectin (P=.445) and C-reactive protein P=.661)] after the switch from the originator adalimumab to MSB11022. There was not a significant reduction in the concomitant use of corticosteroids and thiopurines (P=.157). No emergency room visits or hospitalizations were observed during the study period and none of the patients experienced serious adverse effects. CONCLUSIONS: Between originator adalimumab and biosimilar-start cohorts, no differences were observed, between originator adalimumab and switch cohorts, no significant differences were found either, and with the pre- and post-switch to biosimilar comparison, 2 of the 9 patients experienced AEs after the switch. The biosimilar showed a favorable safety profile (one patient with a serious adverse effect (rash) with biosimilar discontinued treatment) and no significant changes to clinical or biochemical parameters were observed after the switch.

RESUMO

Los fármacos opioides permanecen como fármacos de elección en el tratamiento del dolor agudo postoperatorio y del dolor crónico oncológico. Su prescripción inadecuada, ha dado lugar, en algunos países, a una verdadera «crisis de opioides». En este contexto, puede resultar interesante el potencial terapéutico de algunos ligandos que actúan como moduladores alostéricos de la fijación de los agonistas opioides y su capacidad de modular su actividad, modificando su afinidad, potencia e incluso eficacia. (AU)


Opioids are still the drugs of choice for the treatment of acute post-surgical pain and chronic cancer pain. Overprescribing of these drugs has given rise to an “opioid crisis” in some countries. In this context, attention has been drawn to the therapeutic potential of various ligands that act as allosteric modulators of orthosteric binding sites and modulate the drug's activity, affinity, potency, and even efficacy.

RESUMO

La actividad de nuestras células no solo depende de la secuencia desnuda de ADN sino también de las marcas químicas que controlan el material genético. El nivel regulatorio más reconocido en este ámbito es la epigenética. En la misma destacan la metilación del ADN y las modificaciones post-traduccionales de las histonas que confieren especificidad a la expresión genética y determinan la conformación tridimensional de nuestro genoma. Un segundo componente serían las modificaciones del ARN, un campo conocido como epitranscriptómica. Los cambios químicos de los ARNs tanto los codificantes como los mensajeros determinan la actividad de estas moléculas. Tanto el epigenoma como el epitranscriptoma sufren alteraciones profundas en la enfermedad, particularmente en cáncer. Sin embargo, al tratarse de modificaciones químicas plásticas y dinámicas, es posible revertir las mismas usando distintos principios farmacológicos. Los fármacos epigenéticos, como los inhibidores de la metilación del ADN y la desacetilación de histonas ya han sido aprobados para su uso clínico en oncología. Los fármacos epitranscriptómicos serán los próximos en alcanzar este objetivo.(AU)


The activity of our cells not only depends on the naked DNA sequence but also on the chemical marks that control the genetic material. The most recognized regulatory level in this field is epigenetics. This includes DNA methylation and post-translational modifications of histones that confer specificity to gene expression and determine the three-dimensional conformation of our genome. A second component would be RNA modifications, a field known as epitranscriptomics. Chemical changes in both coding and messenger RNAs determine the activity of these molecules. Both the epigenome and epitranscriptome undergo profound alterations in disease, particularly in cancer. However, since these are plastic and dynamic chemical modifications, it is possible to reverse them using different pharmacological principles. Epigenetic drugs, such as DNA methylation inhibitors and histone deacetylase inhibitors, have already been approved for clinical use in oncology. Epitranscriptomic drugs will be the next to achieve this goal.(AU)

RESUMO

Antecedentes: En España, aunque el Ministerio de Sanidad elabora el informe de posicionamiento terapéutico (IPT) y las condiciones de reembolso de los fármacos, las Comunidades Autónomas (CC. AA.) gestionan los servicios de salud y deciden sobre las condiciones de prescripción en su ámbito territorial. El objetivo del estudio EQUIDAD fue describir los condicionantes para la prescripción de los nuevos fármacos en Dermatología en las CC. AA. y sus posibles diferencias. Material y métodos: Estudio transversal realizado en abril-mayo del 2023. Dos dermatólogos con responsabilidades directivas de cada Comunidad Autónoma (C. A.) informaron sobre los condicionantes autonómicos y locales en la prescripción de los fármacos cuyo IPT para el tratamiento de enfermedades dermatológicas fue publicado en los años 2016-2022. Los datos fueron recogidos mediante un cuestionario online. Resultados: Un total de 33 investigadores de 17 CC. AA. participaron en el estudio. Se observaron inequidades entre CC. AA. para el acceso a los nuevos fármacos. Existieron condicionantes autonómicos adicionales al IPT en psoriasis en el 64,7% de las CC. AA., siendo este porcentaje menor en dermatitis atópica (35,3%) o melanoma (11,8%). El más frecuente fue el requisito de un orden de prescripción previo para el uso del fármaco. En algunas CC. AA. se detectaron además variaciones y condicionantes locales (diferencias entre centros de una misma C. A.). Conclusiones: Existe una multiplicidad de criterios tanto a nivel autonómico como local que añade restricciones adicionales a las establecidas por los IPT y que plantean una situación de inequidad entre los pacientes y los profesionales de las diferentes CC. AA. en el acceso a los nuevos fármacos. (AU)


Background: Although the Spanish Ministry of Health prepares national therapeutic positioning reports (TPRs) and drug reimbursement policies, each of the country's 17 autonomous communities (ACs) is responsible for health care services and prescription requirements in its territory. The aim of the EQUIDAD study was to describe and explore potential differences in prescription requirements for new dermatology drugs across the autonomous communities. Material and methods: Cross-sectional study conducted in April and May, 2023. Two dermatologists with management responsibilities from each autonomous community reported on territorial and more local prescription requirements for drugs covered by national TPRs issued between 2016 and 2022. Results: Thirty-three researchers from 17 autonomous communities participated. The data submitted revealed between-community inequities in access to new drugs. Overall, 64.7% of the regions imposed additional prescription requirements to those mentioned in the TPRs for psoriasis. This percentage was lower for atopic dermatitis (35.3%) and melanoma (11.8%). The most common requirement for accessing a new drug was a previous prescription for another drug. Differences and additional requirements were also detected at the local level (i.e., differences between hospitals within the same autonomous community). Conclusions: Spain's autonomous communities have multiple regional and local prescription requirements that are not aligned with national TPR recommendations. These differences result in inequitable access to new drugs for both patients and practitioners across Spain. (AU)

RESUMO

Background: Although the Spanish Ministry of Health prepares national therapeutic positioning reports (TPRs) and drug reimbursement policies, each of the country's 17 autonomous communities (ACs) is responsible for health care services and prescription requirements in its territory. The aim of the EQUIDAD study was to describe and explore potential differences in prescription requirements for new dermatology drugs across the autonomous communities. Material and methods: Cross-sectional study conducted in April and May, 2023. Two dermatologists with management responsibilities from each autonomous community reported on territorial and more local prescription requirements for drugs covered by national TPRs issued between 2016 and 2022. Results: Thirty-three researchers from 17 autonomous communities participated. The data submitted revealed between-community inequities in access to new drugs. Overall, 64.7% of the regions imposed additional prescription requirements to those mentioned in the TPRs for psoriasis. This percentage was lower for atopic dermatitis (35.3%) and melanoma (11.8%). The most common requirement for accessing a new drug was a previous prescription for another drug. Differences and additional requirements were also detected at the local level (i.e., differences between hospitals within the same autonomous community). Conclusions: Spain's autonomous communities have multiple regional and local prescription requirements that are not aligned with national TPR recommendations. These differences result in inequitable access to new drugs for both patients and practitioners across Spain. (AU)


Antecedentes: En España, aunque el Ministerio de Sanidad elabora el informe de posicionamiento terapéutico (IPT) y las condiciones de reembolso de los fármacos, las Comunidades Autónomas (CC. AA.) gestionan los servicios de salud y deciden sobre las condiciones de prescripción en su ámbito territorial. El objetivo del estudio EQUIDAD fue describir los condicionantes para la prescripción de los nuevos fármacos en Dermatología en las CC. AA. y sus posibles diferencias. Material y métodos: Estudio transversal realizado en abril-mayo del 2023. Dos dermatólogos con responsabilidades directivas de cada Comunidad Autónoma (C. A.) informaron sobre los condicionantes autonómicos y locales en la prescripción de los fármacos cuyo IPT para el tratamiento de enfermedades dermatológicas fue publicado en los años 2016-2022. Los datos fueron recogidos mediante un cuestionario online. Resultados: Un total de 33 investigadores de 17 CC. AA. participaron en el estudio. Se observaron inequidades entre CC. AA. para el acceso a los nuevos fármacos. Existieron condicionantes autonómicos adicionales al IPT en psoriasis en el 64,7% de las CC. AA., siendo este porcentaje menor en dermatitis atópica (35,3%) o melanoma (11,8%). El más frecuente fue el requisito de un orden de prescripción previo para el uso del fármaco. En algunas CC. AA. se detectaron además variaciones y condicionantes locales (diferencias entre centros de una misma C. A.). Conclusiones: Existe una multiplicidad de criterios tanto a nivel autonómico como local que añade restricciones adicionales a las establecidas por los IPT y que plantean una situación de inequidad entre los pacientes y los profesionales de las diferentes CC. AA. en el acceso a los nuevos fármacos. (AU)

RESUMO

OBJECTIVE: To determine the seroprevalence of SARS-CoV-2 in patients with immune-mediated inflammatory diseases (IMID) treated with biologic (bDMARDs) or synthetic targeted disease-modifying antirheumatic drugs (tsDMARDs). METHODS: An observational, descriptive, prospective and cross-sectional study of analytical prevalence analysis was conducted in patients with IMID with bDMARDs or tsDMARDs. Seroprevalence was compared by measuring immunoglobulinG (IgG) against SARS-CoV-2 between October/2020 and May/2021. RESULTS: A total of 550 IMID's patients were studied, all of them on treatment with bDMARDs or tsDMARDs. The seroprevalence of the total patient group was 16% (88/550). Patients receiving therapy with tumor necrosis factor alpha inhibitors (TNFi) had a higher seroprevalence compared to other biologic and synthetic targeted therapies (OR: 1.792 [95%CI: 1.088-2.951]; P=.021). The influence on seroprevalence of concomitant use with b/tsDMARDs of conventional synthetic DMARDs (csDMARDs) was also analyzed. A lower seroprevalence was demonstrated in the group of patients treated with TNFi and methotrexate together, compared with those on TNFi monotherapy, 10.1 vs 24.1% (OR: 0.355 [95%CI: 0.165-0.764]; P=.006). No significant differences were found with the other DMARDs. Regarding IMIDs, no differences in seroprevalence were identified between the different disease groups. CONCLUSION: Patients on treatment with TNFα inhibitors have better humoral response compared to the other b/tsDMARDs. However, when associated with methotrexate the seroprevalence decreases significantly.
