Treatment
Medical Care
- No specific therapy is indicated for Libman-Sacks endocarditis.
- The use of corticosteroids and/or cytotoxic agents for acute enlarging vegetations is controversial. Furthermore, steroid usage is implicated in the formation of leaflet thickening and valvular dysfunction. However, a recent prospective study of 56 patients with primary antiphospholipid syndrome observed that 17 patients (36%) developed new cardiac abnormalities at the 5-year follow-up. New appearances of cardiac involvement were significantly related to high immunoglobulin-G levels and anticardiolipin antibody titers, suggesting that lowering these titers with immune-modulating therapy may prevent the development of cardiac lesions.
- Antibiotic prophylaxis is recommended for prophylaxis of secondary infective endocarditis during procedures precipitating bacteremia (eg, dental work, colonoscopy, rigid bronchoscopy, cystoscopy, colonic surgery). However, these guidelines are not well based on evidence in the case of Libman-Sacks valvular disease.
- Anticoagulation with warfarin is often indicated for atrial fibrillation, mitral stenosis, mechanical heart valves, and thromboembolic events. High-dose anticoagulation is recommended for antiphospholipid syndrome. Case reports of resolution of valvular vegetations after warfarin therapy in patients with antiphospholipid syndrome suggest a role for anticoagulation in the treatment of valvular disease. However, therapeutic trials are lacking.
- The efficacy of aspirin in preventing embolic phenomena with Libman-Sacks endocarditis is undetermined.
- Manage heart failure due to valvular dysfunction according to usual guidelines. Medications might include vasodilators, beta-blockers, diuretics, and digoxin.
- Patients with renal impairment and systemic lupus erythematosus are at slightly increased risk for bone marrow depression and agranulocytosis with ACE inhibitors.
Surgical Care
- Valve replacement might be required for hemodynamically significant valvular dysfunction. Mechanical prostheses are usually implanted. The use of bioprosthetic (tissue) valves is debated because of concerns regarding recurrence of disease and early prosthesis degeneration.
- Although numerous reports of uneventful valve replacement for Libman-Sacks endocarditis have been published, mortality rates in lupus patients have been reported to be as high as 25%.
- Aggressive prophylaxis and treatment of perioperative thrombotic complications are required.
Consultations
- Cardiologist for assistance with the evaluation of the nature and severity of valvular disease, management of heart failure, and evaluation for coexistent lupus cardiac pathology
- Cardiac surgeon if valve replacement is required
- Rheumatologist if underlying systemic lupus erythematosus is suggested
- Infectious disease specialist if sepsis or secondary infective endocarditis is suggested
- Neurologist for cerebrovascular complications
Diet
No special diet is required. However, patients with heart failure might need to avoid excessive sodium intake and patients receiving immunosuppression for systemic lupus erythematosus should avoid products that contain listerial organisms, such as soft cheeses.
Medication
Although no specific therapy is available for Libman-Sacks endocarditis, the following medications can be indicated for the management of valvular disease, complications, and associated conditions.
Antibiotic prophylaxis is recommended for prophylaxis of secondary infective endocarditis during procedures precipitating bacteremia. However, these guidelines are not well based on evidence in the case of Libman-Sacks valvular disease. The specific regimen depends on the nature of the valvular abnormalities, the procedure to be performed, allergies to antibiotics, and prior history of infective endocarditis. Consult guidelines, such as those provided by the American Heart Association, for specific information.
Limited trials have shown symptomatic benefit with ACE inhibitors for patients with mitral regurgitation and preserved left ventricular contractile function. A wide variety of drugs in this category can be used, including benazepril, captopril, enalapril, fosinopril, lisinopril, moexipril, quinapril, ramipril, and trandolapril. Avoid ACE inhibitors in patients with documented hypersensitivity and with a history of angioedema to ACE inhibitors, bilateral renal artery stenosis, severe hypotension, or second- or third-degree heart block in the absence of a pacemaker.
The hypotensive effects of ACE inhibitors can be enhanced when given concurrently with diuretics. Exercise caution in patients with hypovolemia, renal impairment, and hepatic disease. Patients with collagen vascular disease, such as systemic lupus erythematosus and scleroderma, are at slightly increased risk of bone marrow depression and agranulocytosis. Exercise caution in elderly patients; they may have decreased renal function. Hyperkalemia can result with coadministration of potassium-sparing diuretics and potassium supplements. Nonsteroidal anti-inflammatory drugs can potentiate renal dysfunction and reduce the antihypertensive effects of ACE inhibitors. Antacids can decrease the absorption of ACE inhibitors.
Anticoagulants
Indications for anticoagulation include atrial fibrillation, mitral stenosis, mechanical valves, thrombosis, thromboembolism, and antiphospholipid syndrome. Case reports have shown regression of valve masses with the use of anticoagulation, although data are not conclusive. For anticoagulation, warfarin is used regularly.
Warfarin (Coumadin)
Oral anticoagulant that suppresses hepatic synthesis of vitamin K–dependent clotting factors. Well absorbed orally, metabolized in liver, and excreted in urine and feces. Has a half-life of 0.5-1.5 d.
Loading regimen usually used for initiation of therapy. Titrate maintenance dose to desired blood PT and INR; desired INR depends on indication for anticoagulation, age of patient, and risks of bleeding versus thromboses. High-dose anticoagulation (INR 3-4) usually indicated for antiphospholipid syndrome and mechanical valves. Available tab sizes are 1, 2, 2.5, 5, 7.5, and 10 mg.
Adult
5-15 mg/d PO qd for 2-5 d; adjust dose according to desired INR
Pediatric
Not established
Griseofulvin, carbamazepine, glutethimide, estrogens, nafcillin, phenytoin, rifampin, barbiturates, cholestyramine, colestipol, vitamin K, spironolactone, oral contraceptives, and sucralfate can decrease anticoagulant effects; oral antibiotics, phenylbutazone, salicylates, sulfonamides, chloral hydrate, clofibrate, diazoxide, anabolic steroids, ketoconazole, ethacrynic acid, miconazole, nalidixic acid, sulfonylureas, allopurinol, chloramphenicol, cimetidine, disulfiram, metronidazole, phenylbutazone, phenytoin, propoxyphene, sulfonamides, gemfibrozil, acetaminophen, and sulindac can increase anticoagulant effects
Documented hypersensitivity, severe liver or kidney disease, open wounds or GI ulcers, hemophilia, leukemia, blood dyscrasia, bacterial endocarditis, severe hypertension, eclampsia, preeclampsia
Pregnancy
D - Fetal risk shown in humans; use only if benefits outweigh risk to fetus
Precautions
Do not switch brands after achieving therapeutic response; caution in active tuberculosis or diabetes; patients with protein C or S deficiency are at risk of developing skin necrosis
