zithromax and Atrial-Fibrillation

The coronavirus disease 2019 (COVID-19) pandemic has affected millions of people worldwide resulting in significant morbidity and mortality. Arrhythmias are prevalent and reportedly, the second most common complication. Several mechanistic pathways are proposed to explain the pro-arrhythmic effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. A number of treatment approaches have been trialled, each with its inherent unique challenges. This rapid systematic review aimed to examine the current incidence and available treatment of arrhythmias in COVID-19, as well as barriers to implementation.. Our search of scientific databases identified relevant published studies from 1 January 2000 until 1 June 2020. We also searched Google Scholar for grey literature. We identified 1729 publications of which 1704 were excluded.. The incidence and nature of arrhythmias in the setting of COVID-19 were poorly documented across studies. The cumulative incidence of arrhythmia across studies of hospitalised patients was 6.9%. Drug-induced long QT syndrome secondary to antimalarial and antimicrobial therapy was a significant contributor to arrhythmia formation, with an incidence of 14.15%. Torsades de pointes (TdP) and sudden cardiac death (SCD) were reported. Treatment strategies aim to minimise this through risk stratification and regular monitoring of corrected QT interval (QTc).. Patients with SARS-CoV-2 are at an increased risk of arrhythmias. Drug therapy is pro-arrhythmogenic and may result in TdP and SCD in these patients. Risk assessment and regular QTc monitoring are imperative for safety during the treatment course. Further studies are needed to guide future decision-making.

Analysis of the pathogenesis of coronavirus infection caused SARS-CoV-2 indicates a significant impact of hemorheological disorders on its course and outcomes. It is known that chronic cardiovascular diseases are associated with the risk of severe course and lethal outcomes both in COVID-19 and other infectious diseases. Therefore, in each case it is necessary to study the interaction and mutual influence of different components of the treatment program prescribed to such patients.The purpose of this work was to evaluate the effect of coagulation activity on the course of a novel coronavirus infection (COVID-19) and to justify the management of comorbid patients having been received novel oral anticoagulants (NOACs) in previously selected doses according to indications in concomitant somatic diseases.. Total 76 cases of confirmed coronavirus infection in patients who had been received initial therapy on an outpatient basis were analyzed. 26 patients who received NOACs (rivaroxaban, apixaban, dabigatran) made up the main group and 50 - the comparison (control) group in which patients had not been administered any drugs that affect blood clotting until the episode of COVID-19. All patients have been prescribed therapy following the Provisional guidelines «Prevention, diagnosis and treatment of coronavirus infection (COVID-19)» (https://static-0.minzdrav.gov.ru/system/attachments/attaches/).. The number of hospitalizations was significantly fewer in the group of patients who had been received NOACs (19 vs. 66% in the control group). No deaths or cases of severe respiratory and/or renal failure were observed in the main group, while adverse outcomes were noted in 14% of patients who had not been administered these drugs.. Taking NOACs reduces the probability of severe course and adverse outcomes in the development of coronavirus infection caused by SARS-CoV-2, which indicates a significant contribution of coagulation mechanisms to the pathogenesis in COVID-19. There were no indications for drug replacement and correction of anticoagulant therapy regimens in patients who received adequate therapy with oral anticoagulants for treating a non-severe form of coronavirus infection in ambulatory patient settings.

The new coronavirus 2019 epidemic declared in China on December 31, 2019 soon spread to the rest of the world, becoming the subject of an unprecedented health pandemic according to the World Health Organization's declaration of March 11, 2020. It is a disease that has the potential to cause multiple systemic infections. We report here the case of an acute polyradiculoneuritis of the Guillain-Barré type (GBS) indicative of a COVID-19 infection. This is a 41 year old patient seen for ascending, symmetrical and bilateral, progressive and acute tetraparesis with in a context of influenza syndrome and digestive infections treated 2 weeks earlier. During a COVID-19 infection, certain inflammatory cells stimulated by the virus produce inflammatory cytokines creating immune-mediated processes. The same mechanism is observed in GBS being also an immune-mediated disorder. The management of this disease in COVID-19 positive patients does not differ from that of patients who do not carry the virus. The risk of respiratory distress in COVID-19 positive patients becomes twice as great in patients with GBS who test positive for COVID-19 at the same time. Monitoring for hemodynamic disorders and respiratory distress in a neuro-intensive care unit may be fruitful.

Digoxin is commonly prescribed to elderly patients with heart failure and atrial fibrillation, and macrolide antibiotics markedly increase the risk of digoxin toxicity.. The aim was to determine whether, in older patients receiving digoxin, macrolide antibiotics are associated with sudden death.. We used a population-based, nested, case-control design from January 1, 1994 to December 31, 2012 in a cohort of Ontario residents aged 66 years or older prescribed digoxin. The primary outcome was the risk of sudden death within 14 days of exposure to one of three antibiotics (erythromycin, clarithromycin, or azithromycin), relative to cefuroxime.. Among 39,072 Ontarians who died suddenly while receiving digoxin, 586 died within 14 days of receiving a study antibiotic. Relative to cefuroxime, we found no statistically significant increase in the risk of sudden death following treatment with erythromycin [adjusted odds ratio (aOR) 0.98; 95% confidence interval (CI) 0.65-1.48], clarithromycin (aOR 1.25; 95% CI 0.94-1.65), or azithromycin (aOR 1.07; 95% CI 0.75-1.53).. This finding reinforces the cardiovascular safety of macrolide antibiotics in a high-risk population.

A patient with mechanical heart valves developed bleeding, after the introduction of amiodarone and azithromycin. Though the anticoagulant effect could be neutralized, the patient succumbed to heart failure. Any new drug prescribed to patients on anticoagulant must be assessed for its potential for interaction and warrants frequent prothrombin time testing.
