Complement Therapeutics in Autoimmune Disease
Many autoimmune diseases are characterized by generation of autoantibodies that bind to host proteins or deposit within tissues as a component of immune complexes. The autoantibodies can activate the complement system, which can mediate tissue damage and trigger systemic inflammation. Complement inhibitory drugs may, therefore, be beneficial across a large number of different autoimmune diseases. Many new anti-complement drugs that target specific activation mechanisms or downstream activation fragments are in development. Based on the shared pathophysiology of autoimmune diseases, some of these complement inhibitory drugs may provide benefit across multiple different diseases. In some antibody-mediated autoimmune diseases, however, unique features of the autoantibodies, the target antigens, or the affected tissues may make it advantageous to block individual components or pathways of the complement system. This paper reviews the evidence that complement is involved in various autoimmune diseases, as well as the studies that have examined whether or not complement inhibitors are effective for treating these diseases
Caracterizaci贸n de la fibrilaci贸n auricular y riesgo tromboemb贸lico en pacientes del Hospital Le贸n Cuervo Rubio
Introduction: among cardiac pathologies, atrial fibrillation is related to a high incidence of thromboembolic diseases. Objective: to clinically and epidemiologically characterize atrial fibrillation and thromboembolic risk in patients attended at the Le贸n Cuervo Rubio Hospital in Pinar del R铆o between 2017 and 2019. Methods: an observational, descriptive, cross-sectional, descriptive study was conducted on patients with atrial fibrillation attended at the Le贸n Cuervo Rubio Hospital in Pinar del R铆o from 2017 to 2019. The study universe consisted of 198 patients diagnosed with atrial arrhythmias in that hospital, the sample was constituted by 68 patients who met the inclusion and exclusion criteria. Results: female sex predominated (58.8%). The most representative age group was 75 to 85 years old (45.5 %). Some type of heart disease associated with atrial fibrillation was present in 69.1% of patients. Persistent atrial fibrillation predominated (35.2%). Palpitations predominated as symptoms of atrial fibrillation (91.1%). Most patients with atrial fibrillation were in the moderate thromboembolic risk category (66.1%). Conclusions: the predominant sex was female, the most affected age group was over 85 years, ischemic heart disease was the most prevalent history, persistent atrial fibrillation was the most frequent, palpitations were the main symptom, and according to the thromboembolic risk category, most patients were at moderate risk.Introducci贸n: dentro de las patolog铆as cardiacas, la fibrilaci贸n auricular se relaciona con una alta incidencia de enfermedades tromboemb贸licas. Objetivo: caracterizar cl铆nica y epidemiol贸gicamente la fibrilaci贸n auricular y el riesgo tromboemb贸lico en pacientes atendidos en el Hospital Le贸n Cuervo Rubio de Pinar del R铆o entre 2017 y 2019. M茅todo: se realiz贸 un estudio observacional, descriptivo, de corte transversal a pacientes con fibrilaci贸n auricular atendidos en el Hospital Le贸n Cuervo Rubio de Pinar del R铆o de 2017 a 2019. El universo de estudio estuvo conformado por 198 pacientes con diagn贸stico de arritmias auriculares en dicho hospital, la muestra qued贸 constituida por 68 pacientes que cumplieron con los criterios de inclusi贸n y exclusi贸n. Resultados: predomin贸 el sexo femenino (58,8 %). El grupo etario m谩s representativo fue el de 75 a 85 a帽os (45,5 %). El 69,1 % presentaban alg煤n tipo de cardiopat铆a asociada a la fibrilaci贸n auricular. Predomin贸 la fibrilaci贸n auricular de tipo persistente (35,2 %). Predominaron las palpitaciones como s铆ntomas de la fibrilaci贸n auricular (91,1 %). La mayor铆a de los pacientes con fibrilaci贸n auricular estaban en la categor铆a de riesgo tromboemb贸lico moderado (66,1 %). Conclusiones: el sexo que predomin贸 fue el femenino, el grupo et谩reo m谩s afectado fue el de m谩s de 85 a帽os, la cardiopat铆a isqu茅mica fue el antecedente de mayor prevalencia, la fibrilaci贸n auricular de tipo persistente fue la m谩s frecuente, las palpitaciones constituyeron el s铆ntoma principal y seg煤n la categor铆a de riesgo tromboemb贸lico la mayor铆a de los pacientes presentaban riesgo moderado
