Amiodarone-induced lupus-like syndrome
American Journal of Therapeutics
|July 13, 2013
Summary
Amiodarone, used for cardiac arrhythmias, rarely causes drug-induced lupus. This case highlights a rare instance in a 37-year-old male, with complete recovery after stopping the medication.
Area of Science:
- Cardiology
- Rheumatology
- Pharmacology
Background:
- Amiodarone is a widely prescribed antiarrhythmic medication.
- Drug-induced lupus erythematosus (DILE) is a known, albeit uncommon, adverse effect of various medications.
- Rare reports exist linking amiodarone use to the development of DILE.
Observation:
- A 37-year-old male patient was initiated on amiodarone for cardiac arrhythmias.
- Shortly after commencing amiodarone therapy, the patient developed symptoms consistent with lupus erythematosus.
- The clinical presentation and temporal association suggested a drug-induced etiology.
Findings:
- The patient presented with a rare case of amiodarone-induced lupus erythematosus.
- Discontinuation of amiodarone led to a complete resolution of the lupus-like symptoms.
- This case reinforces the potential for amiodarone to induce lupus.
Implications:
- Clinicians should maintain a high index of suspicion for DILE in patients on amiodarone presenting with lupus-like symptoms.
- Early recognition and cessation of amiodarone can lead to favorable patient outcomes.
- Further pharmacovigilance is warranted to better understand the incidence and risk factors for amiodarone-induced lupus.

01:12Antiarrhythmic Drugs: Class III Agents as Potassium Channel Blockers
Class III antiarrhythmic drugs are a group of medications that can prolong action potentials in the heart. They achieve this by blocking potassium channels or enhancing inward currents from sodium channels. However, these drugs have a unique property of "reverse use-dependence," which is most pronounced at slower heart rates and can lead to torsades de pointes—a specific type of arrhythmia. However, it is essential to note that excessive QT interval prolongation—a measure of the heart's...
01:19Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations
The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
01:16Drug toxicity: Idiosyncratic Reactions
Idiosyncratic drug reactions represent abnormal chemical responses that vary significantly among individuals, ranging from extreme sensitivity to low doses to insensitivity to high doses. These reactions often occur due to the drug's covalent binding with serum proteins, forming a foreign hapten that triggers an immunotoxicological response. The variability in drug reactions has a strong pharmacogenetic foundation, with genetic differences crucial in how individuals metabolize drugs. For...

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
