Treatment
Medical Care
Treatment of patients with hereditary lymphedema is primarily directed against the prevention of infection and the control of local complications of limb swelling. Studies in mice, however, suggest that induced overexpression of VEGFR3 ligands stimulate the growth of functional lymphatic vessels.12 An increase in lymphatics would benefit patients with primary and secondary lymphedema.
- Exercise and elevation of the extremity promote movement of fluid away from the lower extremity.
- Elastic stockings and bandages are applied in a gradient fashion, with the highest compression distally and no constriction points.
- Gentle massage or pneumatic compression can be used.
- Proper skin hygiene and use of skin moisturizers prevents drying and fissuring of skin and subsequent bacterial skin infections.
- Use an antistreptococcal antibiotic to treat recurrent cellulitis. Prophylactic antibiotic therapy, such as benzathine penicillin in low doses, may be used to prevent intermittent cellulitis. Antibiotics directed at prophylaxis should have good activity against Streptococcus pyogenes.
- No medication treats or prevents Milroy disease. Complications of this disease, including cellulitis, bacteremia, and chylothorax, are treated as required. Benzopyrones, such as coumarin or diosmin, may stimulate proteolysis of tissue proteins.
Surgical Care
- Several surgical methods have been attempted to benefit patients with Milroy disease, but none has achieved lasting success.
- Excision of the fibrotic subcutaneous tissues with coverage by split-thickness skin grafts has been described.
- Pedicular transfer of skin with healthy lymphatics to the affected limb and anastomosis to existing lymphatic channels has been tried without much success.
Consultations
- Consultation with an infectious disease specialist is indicated for the treatment of recurrent cellulitis.
- In the future, consultation with a geneticist will provide insights into familial inheritance patterns.
Activity
Encourage patients to exercise after a graded support is applied to the involved extremity.
Medication
No medication treats or prevents Milroy disease. Complications of this disease, including cellulitis, bacteremia, and chylothorax, are treated as required. Antistreptococcal antibiotics (eg, cefazolin, clindamycin) can be used to treat cellulitis. Monthly penicillin G benzathine injections may be required to prevent recurrent cellulitis.
Antibiotics
Empiric antimicrobial therapy must be comprehensive and should cover all likely pathogens in the context of this clinical setting.
Cefazolin (Ancef)
First-generation semisynthetic cephalosporin that arrests bacterial cell wall synthesis, inhibiting bacterial growth. Primarily active against skin flora, including Staphylococcus aureus. Typically used alone for skin and skin-structure coverage. IV and IM dosing regimens are similar.
Adult
250 mg to 2 g IV/IM q6-12h, depending on severity of infection; not to exceed 12 g/d
Pediatric
25-100 mg/kg/d IV/IM divided q6-8h, depending on severity of infection; not to exceed 6 g/d
Probenecid prolongs effect; coadministration with aminoglycosides may increase renal toxicity; may yield false-positive urine-dip test results for glucose
Documented hypersensitivity
Pregnancy
B - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals
Precautions
Adjust dose in renal impairment; superinfections and promotion of nonsusceptible organisms may occur with prolonged use or repeated therapy
Clindamycin (Cleocin)
Lincosamide for treatment of serious skin and soft tissue staphylococcal infections. Also effective against aerobic and anaerobic streptococci (but not enterococci). Inhibits bacterial growth, possibly by blocking dissociation of peptidyl t-RNA from ribosomes, causing RNA-dependent protein synthesis to arrest.
Adult
150-450 mg/dose PO q6-8h; not to exceed 1.8 g/d; 600-1200 mg/d IV/IM divided q6-8h, depending on degree of infection
Pediatric
8-20 mg/kg/d PO as hydrochloride and 8-25 mg/kg/d PO as palmitate divided tid/qid; 20-40 mg/kg/d IV/IM divided tid/qid
Increases duration of neuromuscular blockade induced by tubocurarine and pancuronium; erythromycin may antagonize effects; antidiarrheals may delay absorption
Documented hypersensitivity; regional enteritis, ulcerative colitis, hepatic impairment, antibiotic-associated colitis
Pregnancy
B - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals
Precautions
Adjust dose in patients with severe hepatic dysfunction; no adjustment necessary in patients with renal insufficiency; associated with severe and possibly fatal colitis by allowing overgrowth of Clostridium difficile
Penicillin G benzathine (Bicillin)
Interferes with synthesis of cell wall mucopeptides during active multiplication, which results in bactericidal activity. Used to treat syphilis and for prophylaxis of recurrent streptococcal infections.
Adult
1.2 million U IM qmo
Pediatric
25,000-50,000 U/kg IM qmo; not to exceed 1.2 million U/dose
Probenecid can increase effectiveness by decreasing clearance; coadministration with tetracyclines can decrease effectiveness
Documented hypersensitivity
Pregnancy
B - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals
Precautions
Caution in patients with impaired renal function
Anticoagulants
May stimulate proteolysis of tissue proteins.
Warfarin (Coumadin)
Interferes with hepatic synthesis of vitamin K–dependent coagulation factors. Used for prophylaxis and treatment of venous thrombosis, pulmonary embolism, and thromboembolic disorders. Tailor dose to maintain INR of 2-3.
Adult
5-15 mg/d PO for 2-5 d; adjust dose according to desired INR
Pediatric
0.05-0.34 mg/kg/d PO; adjust dose according to desired INR
Drugs that may decrease anticoagulant effects include griseofulvin, carbamazepine, glutethimide, estrogens, nafcillin, phenytoin, rifampin, barbiturates, cholestyramine, colestipol, vitamin K, spironolactone, oral contraceptives, and sucralfate; medications that may increase anticoagulant effects include 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
Documented hypersensitivity; severe liver or kidney disease; open wounds or GI ulcers
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 patients with active tuberculosis or diabetes; patients with protein C or S deficiency are at risk of developing skin necrosis
