Cellulitis

This is often our worst nightmare and sends us to the hospital more than anything else regarding lymphedema. In this section there are many detailed articles on cellulitis, complications of and treatment for cellulitis and/or lymphangitis.

-----------------

Discussion Acute Cellulitis

Acute Cellulitis is one of the complications of lymphedema. The patient may not be aware of the source of the etiology. Sometimes it may be a cut, mosquito bite, open wound or other infection in the body.

The first sign is increased or different quality of PAIN involving the lymphedema limb. The patients often describe this as a "flu like symptom or an ache" involving the Lymphedema arm or leg. This is usually followed by sudden onset of ERYTHEMA(redness, red streaks or blotches) on the involved limb. The HYPERTHERMIA(lymphedema limb becomes warm, hot) will follow and the patient may experience the CHILLS and even HIGH FEVER.

The early intervention and treatment with antibiotics will resolve this condition (it usually takes a very minimum ten day course of antibiotics). Only a Medical Doctor will be able to prescribe the Antibiotics, thus a consultation with a Doctor is necessary. Severe Cellulitis may require Inter venous Antibiotic treatment and hospitalization. Again, elevation of the affected limb is important.

During that phase the patient should NOT massage the lymphedema limb, bandage, apply the pump, wear tight elastic sleeve or exercise excessively. Avoid the blood pressure and blood to be drawn from the involved arm. Keep the limb elevated as much as possible while resting. Once the symptoms dissipate the treatment MLD/CDP should be initiated.

How do we prevent this infection? The patient should be careful with daily activities and take all precautions to protect the skin (wear gloves when gardening, cleaning with detergents, etc... ). If an injury to skin occurs on the lymphedema limb it is necessary to clean the wound with alcohol or hydrogen peroxide and apply Neosporin/Polysporin antibiotic ointment. If the symptoms progress seek the attention of a physician immediately.It is so very important to avoid getting cellulitus as it furtherdestroys the lymphatic system. Allowed to spread or continue it can become systemic and can lead to gangrene, amputation of the limb or even death.

Clinical

Cellulitis is clinically a spreading infection involving both the dermis and subcutaneous tissues. Unlike erysipelas, it will not have a clear raised border. Other features may include red streaking from the infected area, regional lymphadenopathy.

Symptoms

Symptoms include all over body ache, fever, severe pain of the infected area, chills, weakness. The skin color will be red, warm and very tender to the touch.

Causes

The most common bacteria responsible for cellulitis infections are staph aureus and strep A. Other less common bacterial agents include Step B, gram-negative bacteria, and immunocompromised patients pneumococcus. Less common bacteria such as Hemophilus influenzae, Pasturella multocide, and erysipelothrix rhusiopathiae can cause it as well.

Entry foci for the bacteria includes nasal cavities, wound, cuts, scrapes (any type of skin break). Insect bites (especially spider) can cause the condition. Cat scratches, animal bites are another source of bacteria.

Risk Factors

Patients with any of the following disorders are more at risk for developing serious and or life threatening cellulitis:

Lymphedema, Diabetes, immunodeficiency (of any type), Varicella (cellulitis as a complication of), chemo therapy patients, venous insufficiency or venous stasis, chronic steroid users, post surgical patients, individuals with edema and finally age may also be a factor with infants and the elderly more susceptible to infections.

Complications

Complications can include septicemia, tissue necrosis, gangrene, amputation of the affected limb, death. It should be noted also that cellulitis causes further damage to the lymphatics and thereby makes lymphedema worse. Other complications include lymphangitis, skin abcesses.
In compromised patients, physicians must be careful to observe for a complicating gram-negative super infection that can accompany regular gram-positive bacteria. This can occur asa result of the even further depletion of the body's immune system.


Treatment

Cellulitis responds well to antibiotic therapy. Generally, a ten day course of treatment is prescribed. Antibiotics used to treat cellulitis include Keflex, Augmentin, penicillins. Unasyn and vancomycin are standard IV antibiotics. In situations of a gram negative infection, Gentamicin is used.

For special at risk patients, blood work may also be indicated to assure the infection has not become systemic.

This group, which includes lymphedema patients may need extended IV antibiotic therapy.

Prognosis

With early diagnosis and subsequent rapid treatment the outcome is actually excellant with the overwhelming number of patients making full recovery. In special risk groups however, there is a heightened risk of complication and morbidity.

--------------------

Signs of secondary infection - The signs of infection can often be negligible and the therapist must be extremely vigilant for them. The physician may prescribe antibiotic therapy if he or she suspects it. Signs of SAI can also be unmistakable with high fever and chills; the patient may require a ten-day hospitalization with intravenous antibiotic therapy.

Clinical signs of infections: - Minor rash or red streaks may be visible. Any of the following may be present or not:: Itching, tenderness, dull aching in a limb, blotchy areas, small blisters, general malaise, etc. In septicemia fever, chills and nausea are common. The signs may include aggravation of the lymphedema condition: Increase in edema volume so that the medical compression feels too tight for reasons that are unclear. Lymph nodes may become enlarged, or pain may occur in lymph nodes. There may be an elevation of temperature of the extremity. Pain may appear or increase, with tender spots, heaviness, tightness, tiredness, etc. Fistulae (lymphorrhea) may also occur; the reason for this is not known.

Chronic secondary infections are more difficult to assess, with slight elevation in skin temperature, increased sensitivity, slight itching or redness. Sometimes the redness (erythema) is not present if the infection is situated deep in the tissue. This condition may be pain-free in a patient whose affected limb is numb. Some episodes of infection are milder and resolve in a few days without antibiotic treatment. Fungusor staphylococcus may be the agents causing these kinds of infections.

D- Prevention of Secondary Infection: - Decongestion of the edema - Extremely careful skin care - Prophylactic antibiotic therapy may be suggested by the physician in cases of recurrent SAI. Allergic inquiry / test is recommended first.

E- Treatment: The therapist should be able to work with a medical team. It is imperative to check with a physician if there is any suspicion of secondary infection, and scrupulously treat any infection. Hands-on lymphatic drainage and medical compression (bandages, garments) should be interrupted until the condition is under control (at least 48 to 72 hours, up to 8 days).
The signs of infections (edema, erythema, warmth, aching, etc.) should have clearly disappeared. Antibiotic therapy: Bacterial infection calls for immediate antibiotic therapy. The sensitivity of the bacteria to antibiotics (regular penicillin G) is generally good.

Suggested treatment (Olszewski W.L.): first episode: 3 months of antibiotic therapy. If there are more than two episodes, one year's antibiotic therapy may be indicated. Check for the few adverse effects of prolonged antibiotic therapy: change in intestinal flora, gastro-intestinal disorders, damage to liver, kidneys and bones, allergic reactions, etc. Where the patient is allergic to penicillin, erythromycin usually works well. After one episode of infection, it may be wise for lymphedema patients to carry a supply of antibiotics or a prescription with them, especially when traveling away from home.
