Amiodarone is a benzofuran derivative with a chemical structure similar to thyroxine. Originally introduced to treat angina pectoris, amiodarone was found to have antiarrhythmic properties, and in 1985, was approved in the United States for treatment of life-threatening ventricular arrhythmias. It is now used for various ventricular and supraventricular arrhythmias refractory to conventional first-line medications, and as a result, side effects have been observed with increased frequency. The most severe and potentially life-threatening of these side effects is the development of pulmonary toxicity. Typically, amiodarone pulmonary toxicity (APT) is manifested by acute pneumonitis and chronic fibrosis. Amiodarone-associated hemoptysis (AAH) is a rare occurrence. The authors describe a case of AAH successfully treated with cessation of drug and steroid therapy.

The authors describe a case of a 74-year-old man with advanced coronary heart disease in whom pulmonary hemorrhagic complications during therapy with ticlopidine and subsequently with clopidogrel and amiodarone were observed. Fever and massive hemoptysis following five days of ticlopidine treatment, before elective coronary angiography, were noticed. Transient interstitial X-ray changes of the right lung were visible. Three months later a new episode on the third day of clopidogrel administration was manifested. He was after PCI, performed because of ACS complicated with ventricular fibrillation. Two days following clopidogrel discontinuation hemoptysis remitted but after ten days occurred again (this time with bilateral X-ray changes). Amiodarone, given after VF, was stopped. Spectacular improvement with steroid treatment was observed. Indobufen (reversible COX- 1 inhibitor) as an antiplatelet therapy was availed. The authors discuss therapeutic dilemma concerning the patient with coexisting different diseases.

Amiodarone pulmonary toxicity (APT) is a common and distinctive form of drug-induced lung injury. Several patterns have been described and the most common pattern of APT is interstitial pneumonitis. However, amiodarone-induced diffused alveolar haemorrhage is rarely reported. We describe a case of early onset of APT manifested by respiratory distress, haemoptysis, severe hypoxia and bilateral pulmonary infiltrates that was finally diagnosed with amiodarone-induced diffuse alveolar haemorrhage. High suspicion of APT in patients with these non-specific clinical symptoms is needed. Early recognition and treatment are imperative.

The patient was a 26 year-old man who was referred to our hospital in June 2011 because of severe heart failure. At age 24 years, he was found to have Becker muscular dystrophy. He received enalapril for cardiac dysfunction; however, he had worsening heart failure and was thus referred to our hospital. Echocardiography showed enlargement of the left ventricle, with a diastolic dimension of 77 mm and ejection fraction of 19%. His condition improved temporarily after an infusion of dobutamine and milrinone. He was then administered amiodarone for ventricular tachycardia; however, he subsequently developed hemoptysis. Amiodarone was discontinued and corticosteroid pulse therapy was administered followed by oral prednisolone (PSL). His creatinine phosphokinase (CPK) level and cardiomegaly improved after the corticosteroid therapy. The PSL dose was reduced gradually, bisoprolol was introduced, and the catecholamine infusion was tapered. A cardiac resynchronization device was implanted; however, the patient's condition gradually worsened, which necessitated dobutamine infusion for heart failure. We readministered 30 mg PSL, which decreased the CPK level and improved the cardiomegaly. The dobutamine infusion was discontinued, and the patient was discharged. He was given 7.5 mg PSL as an outpatient, and he returned to normal life without exacerbation of the heart failure. There are similar reports showing that corticosteroids are effective for skeletal muscle improvement in Duchenne muscular dystrophy; however, their effectiveness for heart failure has been rarely reported. We experienced a case of Becker muscular dystrophy in which corticosteroid therapy was effective for refractory heart failure.

Amiodarone-induced pulmonary toxicity (APT) is one of the most feared and underappreciated adverse effects of this commonly prescribed antiarrhythmic. APT has a variable presentation, among the rarest of these is amiodarone-induced diffuse alveolar hemorrhage with hemoptysis. Though previous cases confirmed with biopsy averaged a dose of 570 mg PO daily, APT can occur at any dose. Previous literature has suggested the importance of cumulative exposure to amiodarone rather than the patient's actual dose. The presented case describes amiodarone-induced hemoptysis occurring at a dose of 200 mg PO daily for five years. Additionally described is the treatment regimen which managed a patient with metabolic syndrome and elevated A1c while addressing the recommended treatment of extended high-dose steroids for APT with complicated respiratory status. To the best of the authors' knowledge, only two biopsied cases have been described at a dose this low. Furthermore, this case describes a more typical timeline for APT than those two cases.

Amiodarone is an antiarrhythmic agent that is used commonly in clinical practice. It is associated with many side effects, the most common being pulmonary manifestations. Interstitial pneumonitis is one of the most common complications, however rarely amiodarone can cause diffuse alveolar haemorrhage (DAH) too. We describe the case of a 73-year-old woman who presented with shortness of breath and haemoptysis 4 days after starting amiodarone. She was diagnosed with amiodarone-induced DAH based on imaging and bronchoalveolar lavage. She was treated with intravenous and then oral steroids, and amiodarone was discontinued. The patient made a significant clinical and radiological recovery. She was discharged 10 days after her presentation. This case highlights a rare but potentially life-threatening complication of a commonly used medication.
