A rare case of Diffuse Alveolar Hemorrhage (DAH) due to warfarin toxicity.
Warfarin is one of the most frequently used anticoagulant agents in the clinic. The most important adverse effect of warfarin is hemorrhage of vital organs, such as lung and brain. Diffuse Alveolar Hemorrhage (DAH) is a rare clinical condition which occurs due to variety of medical disorders. Although it's rarely reported, DAH can be a result of coagulopathy prompted by warfarin therapy. In this study we present a case of DAH, caused by warfarin toxicity which referred to the hospital with non-specific respiratory symptoms.. A 41-year-old female patient referred to the hospital complaining of shortness of breath, cough and dizziness. She had been taking warfarin due to mitral valve replacement for the past 10 years. Her recent symptoms began shortly after taking amoxicillin, a few days before admission. Early clinical examination and paraclinical studies reveal DAH as the cause of respiratory symptoms. The patient was then intubated and received fresh frozen plasma, packed cells and oral vitamin K. Laboratory findings apart from increased INR, PT, ESR and CRP were all within normal range. After the initiation of treatment patient's INR decreased and her clinical condition improved. Follow-up CT-Scan and bronchoscopy also confirmed resolving DAH.. The usage of warfarin in anticoagulation should be closely monitored due to its narrow therapeutic window and other factors, including its interaction with other medications such as antibiotics. Warfarin toxicity can lead to DAH, a life-threatening condition which can be presented with non-specific symptoms and deteriorate patient's clinical condition in a short time. Therefore, it is of utmost importance to watch closely for primary symptoms of such rare incident in patients under warfarin therapy and initiate treatment as soon as possible, to prevent mortality.

Nocardial endocarditis in native aortic valve with nocardial sepsis in a case of breast cancer.
Central venous catheter-associated bacteraemia caused by Nocardia species is very rare; the diagnosis of nocardiosis in patients with cancer is challenging because its clinical presentation is varied, sometimes mimicking metastases, and the high index of clinical suspicion is required for prompt institution of therapy. Herein, we report a case of nocardial sepsis with native aortic valve endocarditis in a patient with breast cancer in whom multidisciplinary team involvement and prompt initiation of therapy have led to successful outcome. Topics: Amikacin; Anti-Bacterial Agents; Anticoagulants; Aortic Valve; Breast Neoplasms; Central Venous Catheters; Clopidogrel; Cough; Endocarditis, Bacterial; Fatigue; Female; Headache; Heart Valve Prosthesis Implantation; Humans; Meropenem; Middle Aged; Nocardia; Nocardia Infections; Platelet Aggregation Inhibitors; Radiography, Thoracic; Sepsis; Treatment Outcome; Warfarin | 2019 |
A case of tricuspid valve non-bacterial thrombotic endocarditis presenting as pulmonary embolism in a patient with antiphospholipid antibody syndrome.
A 47-year-old woman with a medical history of Raynaud's phenomenon presented with fever, cough and shortness of breath. She was found to have left lower lobe consolidation and pleural effusion and was treated as a case of pneumonia. During the hospital course, her respiratory status worsened, and she was intubated on the third hospital day. To investigate the high A-a gradient, a Computerized Tomographic Pulmonary Embolism (CTPE) study was done which identified a large left lower pulmonary artery embolism. She was also found to have a new murmur, and an echocardiogram demonstrated a large lesion on tricuspid valve. However, multiple sets of her blood cultures came back consistently negative. Alternative diagnoses for culture-negative endocarditis were considered, and a full set of rheumatological workup was done. Laboratory tests were suggestive of antiphospholipid syndrome, hence the diagnosis of tricuspid valve Libman-Sacks endocarditis was made.

Use of contrast-enhanced computed tomography for management of a late-onset spontaneous massive chest wall hematoma.
This is a rare case of a 68-year-old woman who was rehospitalized after uneventful redo double-valve surgery. An 8.3 × 12.9 × 16.4 cm tense right chest wall hematoma was diagnosed. This was precipitated by a single cough. Contrast-enhanced computed tomography revealed a bleeding source. Hematoma evacuation and hemostasis following emergency warfarin reversal produced an excellent outcome.

Clinically significant interaction between warfarin and popular cough lozenges 'Fisherman's Friend'.
The authors report a highly probable and clinically relevant interaction between warfarin and the popular cough lozenges 'Fisherman's Friends' in a 67-year-old man, whereby ingestion of these lozenges for approximately 1 month was associated with a significant reduction in international normalised ratio to subtherapeutic levels.

Probable warfarin interaction with menthol cough drops.
Warfarin is a widely used and effective oral anticoagulant; however, the agent has an extensive drug and food interaction profile. We describe a 46-year-old African-American man who was receiving warfarin for a venous thromboembolism and experienced a decrease in his international normalized ratio (INR). No corresponding reduction had been made in his warfarin dosage, and no changes had been made in his concomitant drug therapy or diet. The patient's INR fell from a therapeutic value of 2.6 (target range 2-3) to 1.6 while receiving a weekly warfarin dose of 50 mg. His INR remained stable at 1.6 for 3 weeks despite incremental increases in his warfarin dose. The patient reported that he had been taking 8-10 menthol cough drops/day due to dry conditions at his workplace during the time period that the INR decreased. Five days after discontinuing the cough drops, his INR increased from 1.6 to 2.9. Over the subsequent 5 weeks, his INR was stabilized at a much lower weekly warfarin dose of 40 mg. Use of the Naranjo adverse drug reaction probability scale indicated that the decreased INR was probably related to the concomitant use of menthol cough drops during warfarin therapy. The mechanism for this interaction may be related to the potential for menthol to affect the cytochrome P450 system as an inducer and inhibitor of certain isoenzymes that would potentially interfere with the metabolism of warfarin. To our knowledge, this is the second case report of an interaction between warfarin and menthol. Patients receiving warfarin should be closely monitored, as they may choose to take over-the-counter products without considering the potential implications, and counseled about a possible interaction with menthol cough drops.

A case of isolated peripheral pulmonary artery branch stenosis associated with multiple pulmonary artery aneurysms.
Selective right pulmonary arteriography and 3-dimensional computed tomography revealed multiple severe stenoses of the peripheral pulmonary artery associated with poststenotic aneurysms in a 65-year-old woman. She was referred to the hospital for evaluation of dry cough, gradually increasing dyspnea and multiple nodular shadows on a chest radiograph. Echocardiography and cardiac catheterization showed severe pulmonary hypertension, though other structural heart diseases or well-characterized congenital syndromes were ruled out. She was diagnosed as isolated peripheral pulmonary artery branch stenosis. Recent advances in CT technology enable a less-invasive assessment of pulmonary artery, and can be useful in the management of pulmonary arterial hypertension.

Possible warfarin interaction with menthol cough drops.
To report a case of possible interaction of menthol cough drops (Halls) with warfarin in a patient awaiting cardioversion.. A 57-year-old white male awaiting cardioversion for atrial fibrillation was prescribed warfarin. His dosage was adjusted to 7 mg daily to provide stable international normalized ratio (INR) values of 2.28-2.68. Approximately one week later, his INR fell to 1.45. During a follow-up interview, the patient reported that he experienced a flu-like illness during the previous week and had been using menthol cough drops. No other potential causes for the decreased INR were found. Illness will most often elevate the INR; we therefore concluded that the cough drops were the likely cause of this reaction, and the warfarin dose was increased to 53 mg/wk. After discontinuing use of menthol cough drops, the warfarin dose was returned to the previous amount and the INR remained stabilized.. An objective causality assessment suggests that the decreased INR was possibly related to the use of menthol cough drops during warfarin therapy. The active ingredient in these cough drops is menthol. Menthol has been shown to affect the pharmacokinetics of other drugs by inducing or inhibiting cytochrome P450 isoenzymes and slowing drug absorption. It is not clear whether these mechanisms played a role in this case. As of January 5, 2005 this is the first case report documenting an interaction between warfarin and cough drops containing menthol.. This case documents a significant decrease in the INR following the use of menthol cough drops. Patients who are ill have several factors that can potentially affect their INR and should be monitored closely.
