Predisposition To Infection: Neutropenia
Patients with neutropenia are predisposed to infection because of insufficient circulating neutrophils, lack of adequate myeloid marrow reserve, or congenital or acquired defects in neutrophil function . Neutropenia is frequently associated with mucosal or integumentary barrier disruption, and the indigenous colonizing florae are responsible for most infections. More than 20% of patients with chemotherapy-induced neutropenia develop skin and soft-tissue infections, many of which are due to hematogenous dissemination from other sites, such as the sinuses, lungs, and the alimentary tract . Important pathogens for neutropenic patients can be separated into organisms most likely to cause an initial infection and those more likely to cause a subsequent infection . Pathogens causing initial infections are usually bacteria, including both gram-negative and gram-positive organisms. Pathogens causing subsequent infections are usually antibiotic-resistant bacteria, yeast, or fungi .
Skin and soft-tissue infections in the immune compromised host: treatment and management.
How Is A Skin Infection Treated
Treatment depends on the cause of the infection and the severity. Some types of viral skin infections may improve on their own within days or weeks.
Bacterial infections are often treated with topical antibiotics applied directly to the skin or with oral antibiotics. If the strain of bacteria is resistant to treatment, treating the infection may require intravenous antibiotics administered in the hospital.
You can use over-the-counter antifungal sprays and creams to treat a fungal skin infection. If your condition doesnt improve, ask your doctor about prescription oral or topical creams. In addition, you can apply medicated creams to your skin to treat parasitic skin infections. Your doctor may also recommend medications to reduce discomfort like anti-inflammatory drugs.
Clinical Manifestations Of Inflammation
The cardinal manifestations of inflammation are warmth, erythema, edema, pain and dysfunction . Prolonged inflammation can lead to chronic edema, especially in the lower extremities, and can result in a postcellulitic syndrome. Ancillary systemic signs, such as fever, hypotension and tachycardia, result from cytokine-induced changes in thermoregulation and vascular resistance. The release of cytokines may be mediated by the normal immune cell function or by bacterial toxin stimulation. Out-of-proportion pain results from severe damage of the deep layers of skin produced by bacterial toxins, while bullous lesions are produced by toxin-mediated epidermal cleavage. Skin anesthesia, which may be present during the course of necrotizing fasciitis, occurs secondary to toxin-mediated nerve tissue damage. Also, violaceous lesions result from toxin-mediated lysis of erythrocytes and hemorrhage .

Are There Any Over
Over-the-counter oral antibiotics are not approved in the U.S. A bacterial infection is best treated with a prescription antibiotic that is specific for the type of bacteria causing the infection. Using a specific antibiotic will increase the chances that the infection is cured and help to prevent antibiotic resistance. In addition, a lab culture may need to be performed to pinpoint the bacteria and to help select the best antibiotic. Taking the wrong antibiotic — or not enough — may worsen the infection and prevent the antibiotic from working the next time.
There are a few over-the-counter topical antibiotics that can be used on the skin. Some products treat or prevent minor cuts, scrapes or burns on the skin that may get infected with bacteria. These are available in creams, ointments, and even sprays.

Some common oral or injection treatments for skin conditions include:
- Antibiotics: Oral antibiotics are used to treat many skin conditions. Common antibiotics include dicloxacillin, erythromycin, and tetracycline.
- Antifungal agents: Oral antifungal drugs include fluconazole and itraconazole. These drugs can be used to treat more severe fungal infections. Terbinafine is an oral antifungal medicine that may be used to treat fungal infections of the nails.
- Antiviral agents: Common antiviral agents include acyclovir , famciclovir , and valacyclovir . Antiviral treatments are used for skin conditions including those related to herpes and shingles.
- Corticosteroids: These medications, including prednisone, can be helpful in treating skin conditions linked to autoimmune diseases including vasculitis and inflammatory diseases such as eczema. Dermatologists prefer topical steroids to avoid side effects however, short-term use of prednisone is sometimes necessary.
- Immunosuppressants: Immunosuppressants, such as azathioprine and methotrexate , can be used to treat conditions including severe cases of psoriasis and eczema.
Surgical Examination And Drainage
Urgent consultation with a surgeon should be sought in the setting of crepitus, circumferential cellulitis, necrotic-appearing skin , evolving bullae, rapidly evolving cellulitis, pain disproportional to physical examination findings, severe pain on passive movement, or other clinical concern for necrotizing fasciitis. Wong et al have developed a scoring tool to assist in the diagnosis of necrotizing fasciitis. Cellulitis associated with an abscess requires surgical drainage of the source of infection for adequate treatment.
Serious concern for necrotizing fasciitis and/or the presence of necrotic skin should prompt examination of the fascial planes by immediate computed tomographic imaging or surgical direct observation, which, in most cases, can be performed at the bedside by an experienced surgeon. Circumferential cellulitis may result in compartment syndrome, which may require surgical decompression. Measurement of compartment pressures may be helpful in diagnosis.

Cautions With Other Medicines
Some medicines can affect the way that flucloxacillin works and increase the chance of you having side effects.
Tell your doctor if you’re taking any of these medicines before you start flucloxacillin:
- methotrexate, an anti-inflammatory medicine for arthritis and similar conditions
- warfarin, a medicine to prevent blood clots
- other antibiotics
Tell your doctor if you’ve recently had, or are due to have, an oral typhoid vaccination. Flucloxacillin can make it less effective.
Swelling And Redness In Your Lower Legs May Not Require Treatment With Antibiotics
If one or both of your lower legs are swollen and red, visit your doctor to find out why. In most cases, if both of your lower legs are swollen and red at the same time, its not because of an infection. That means you dont need antibiotics.

Antibiotics Can Be Harmful
If you have an infection, antibiotics can save your life. But antibiotics can also be harmful if you take them when you dont need them. The more antibiotics you use, the less likely they are to work when you need them.
Antibiotics can cause side effects. Antibiotics that you take by mouth can cause upset stomach, vomiting, diarrhea, and vaginal yeast infections. They can also cause allergic reactions. These include rashes, swelling, itching, and trouble breathing. Side effects from antibiotics cause nearly 1 in 5 trips to the emergency department.
Antibiotic creams and ointments can slow the healing of wounds. And they can cause redness, swelling, blistering, draining, and itching.
Antibiotics can breed superbugs. More than half of all antibiotics used in the U.S. are not needed. Thats according to the Centers for Disease Control and Prevention. Taking antibiotics when you dont need them can breed superbugs. These are bacteria that are hard to kill. They can make it harder to get well and cause health problems. You can spread superbugs to other people.
Antibiotics can be a waste of money. Antibiotics that you take by mouth can cost from $8 to more than $200. Antibiotic creams and ointments can cost from $5 to more than $150. Plus, you may need to spend more on healthcare and treatments due to side effects and superbugs from antibiotics.
People At Risk Of Bacterial Infections
Antibiotics may also be recommended for people who are more vulnerable to the harmful effects of infection. This may include:
- people aged over 75 years
- babies less than 72 hours old with a confirmed bacterial infection, or a higher than average risk of developing one
- people with heart failure
- people who have to take insulin to control their diabetes
- people with a weakened immune system either because of an underlying health condition such as HIV infection or as a side effect of certain treatments, such as chemotherapy

Top 4 Antibiotic Treatments For Internal Or Severe Infections
Hospitalized patients with more complicated or severe forms of infections are often prescribed one of the following four antibiotics. These infections can include deep soft-tissue infections, surgical infections, major abscesses, wound infections and burn patients.
Oftentimes a broad-spectrum antibiotic is used in conjunction with the following antibiotics. Most options below use intravenous methods of delivering antibiotics into the body. A picc line may be used for prolonged treatment.
1. Intravenous Vancomycin
Vancomycin is often called an antibiotic of last resort for MRSA, though resistance against it has been growing. Vancomycin requires IV administration into a vein and can occasionally have severe side effects. Duration of treatment can last weeks to months. Tissue penetration is variable and it has limited penetration into bone. Its often prescribed for pneumonia .
- Resistance: Some strains of MRSA are now becoming resistant to Vancomycin, with one strain called VRSA .
- Side Effects and Precautions: Serious side effects can include ringing in ears, diarrhea, and hearing problems. Like most antibiotics, it can cause secondary infections like thrush or yeast infections. Because this medication is eliminated through the kidneys, it could cause kidney problems in the elderly or those with impaired kidney function.
