ABSTRACT
Introduction: Cases of acute myocarditis have been after administration of the BNT162b2 and Ad26.COV2.S vaccine. Objective: Describe another possible mechanism of myocarditis after COVID-19 vaccination. Case presentation: We describe the clinical case of a 72-year-old female with pleuritic chest pain one week after the third of the BNT162b2 mRNA vaccine. Serological tests for cardiotropic pathogens were negative, and autoimmunity screening was positive with anti-nuclear antibody (ANA) in 1:160 dilution, Anti-double-stranded DNA (anti-dsDNA), and anti-histone antibodies. 18F-fluoro-deoxy-glucose (FDG) positron emission tomography/computed tomography (PET/CT) showed a focal myocardial and pericardial inflammatory process in the cardiac apex. Results and discussion: Systemic lupus erythematosus (SLE) diagnosis was made with myocardial affection. As far as we know, this is the first report of a case of lupus myocarditis after the COVID-19 vaccine. Conclusion: Given the pathogenic rationales, the association between SLE and myocarditis should be considered.
Introducción: Se han presentado casos de miocarditis aguda tras la administración de las vacunas BNT162b2 y Ad26.COV2.S. Objetivo: Describir otro posible mecanismo de miocarditis posterior a la vacunación contra el COVID-19. Presentación del caso: Describimos el caso clínico de una mujer de 72 años con dolor torácico pleurítico una semana después de la tercera vacuna de ARNm BNT162b2. Las pruebas serológicas para patógenos cardiotrópos fueron negativas y el cribado de autoinmunidad fue positivo con anticuerpos antinucleares (ANA) en dilución 1:160, anticuerpos anti-ADN de doble cadena (anti-dsADN) y antihistonas. La tomografía por emisión de positrones/tomografía computarizada (PET/TC) con 18F-fluorodesoxiglucosa (FDG) mostró un proceso inflamatorio miocárdico y pericárdico focal en el ápex cardíaco. Resultados y discusión: Se realizó el diagnóstico de lupus eritematoso sistémico (LES) con afectación miocárdica. Hasta donde sabemos, este es el primer reporte de un caso de miocarditis lúpica después de la vacuna contra el COVID-19. Conclusión: Dadas las justificaciones patogénicas, se debe considerar la asociación entre lupus eritematoso sistémico (LES) y miocarditis.

ABSTRACT
BACKGROUND: Ivermectin inhibits the replication of SARS-CoV-2 in vitro at concentrations not readily achievable with currently approved doses. There is limited evidence to support its clinical use in COVID-19 patients. We conducted a Pilot, randomized, double-blind, placebo-controlled trial to evaluate the efficacy of a single dose of ivermectin reduce the transmission of SARS-CoV-2 when administered early after disease onset. METHODS: Consecutive patients with non-severe COVID-19 and no risk factors for complicated disease attending the emergency room of the Clínica Universidad de Navarra between July 31, 2020 and September 11, 2020 were enrolled. All enrollments occurred within 72 h of onset of fever or cough. Patients were randomized 1:1 to receive ivermectin, 400 mcg/kg, single dose (n = 12) or placebo (n = 12). The primary outcome measure was the proportion of patients with detectable SARS-CoV-2 RNA by PCR from nasopharyngeal swab at day 7 post-treatment. The primary outcome was supported by determination of the viral load and infectivity of each sample. The differences between ivermectin and placebo were calculated using Fisher's exact test and presented as a relative risk ratio. This study is registered at ClinicalTrials.gov: NCT04390022. FINDINGS: All patients recruited completed the trial (median age, 26 [IQR 19-36 in the ivermectin and 21-44 in the controls] years; 12 [50%] women; 100% had symptoms at recruitment, 70% reported headache, 62% reported fever, 50% reported general malaise and 25% reported cough). At day 7, there was no difference in the proportion of PCR positive patients (RR 0·92, 95% CI: 0·77-1·09, p = 1·0). The ivermectin group had non-statistically significant lower viral loads at day 4 (p = 0·24 for gene E; p = 0·18 for gene N) and day 7 (p = 0·16 for gene E; p = 0·18 for gene N) post treatment as well as lower IgG titers at day 21 post treatment (p = 0·24). Patients in the ivermectin group recovered earlier from hyposmia/anosmia (76 vs 158 patient-days; p < 0.001). INTERPRETATION: Among patients with non-severe COVID-19 and no risk factors for severe disease receiving a single 400 mcg/kg dose of ivermectin within 72 h of fever or cough onset there was no difference in the proportion of PCR positives. There was however a marked reduction of self-reported anosmia/hyposmia, a reduction of cough and a tendency to lower viral loads and lower IgG titers which warrants assessment in larger trials.
