Necrotizing Skin And Soft

streptococcal skin infections – Impetigo, Ecthyma, Cellulitis, Erysipelas, Necrotising Fasciitis

Necrotizing skin and soft-tissue infections differ from the milder, superficial infections by clinical presentation, coexisting systemic manifestations, and treatment strategies . They are often deep and devastating. They are deep because they may involve the fascial and/or muscle compartments they are devastating because they cause major destruction of tissue and can lead to a fatal outcome. These conditions are usually secondary infections, in that they develop from an initial break in the skin related to trauma or surgery. They can be monomicrobial or polymicrobial . Although many specific variations of necrotizing soft-tissue infections have been described on the basis of etiology, microbiology, and specific anatomic location of the infection, the initial approach to the diagnosis, antimicrobial treatment, and decision to use operative management are similar for all forms and are more important than determining the specific variant.

What Type Of Doctors To See

Dermatologists specialize in diagnosing and treating skin conditions. A dermatologist can determine whether your skin infection is caused by strep bacteria or another type of bacteria. They can prescribe antibiotics and give advice to help you care for your skin. If you have an underlying skin condition, such as eczema, that makes you more likely to develop streptococcal skin infections, a dermatologist can help you manage it over the long term. Doing so could help to reduce your risk of future infections.

How Can I Reduce My Risk Of Spreading Or Getting Group A Streptococcal Infections

Even though there is no vaccine to prevent group A streptococcal infections, you can reduce your risk of getting an infection or spreading infection by having good hygiene. Good hygiene includes:

  • Washing your hands with soap and water often.
  • Covering your mouth and nose when you cough or sneeze.
  • Throwing away your tissues after using them.
  • Washing utensils, plates and glasses after someone who is sick uses them.
  • Staying home if you feel sick.
  • Cleaning and covering wounds until they heal.

Genetic Control Of Virulence Factors

Control of virulence factor gene expression over time and under diverse environmental conditions depends on multiple complex and interrelated genetic systems . Of the known transcriptional regulators in S. pyogenes, the most intensively studied include Mga , Mry , and a two-component regulatory system known as CsrRS or, alternatively, as CovRS , which represses the synthesis of the hyaluronic acid capsule and several exotoxins. The regulator of proteinase B has also been shown to have multiple polymorphisms that control the virulence of S. pyogenes .

Is Staph A Sexually Transmitted Infection

Antibiotics can be used to treat staph infections. At the same time, we do not consider staphylococcus aureus to be a sexually transmitted illness, although it is carried from skin to skin contact. Staph bacteria are found in the nose of about half of the population and only cause problems when the number increases. Using antibiotics to treat staph infections where they are not needed can lead to their development of resistance.

What Is Group A Streptococcus

Group A streptococci are bacteria commonly found in the throat and on the skin. The vast majority of GAS infections are relatively mild illnesses, such as strep throat and impetigo. Occasionally, however, these bacteria can cause much more severe and even life threatening diseases such as necrotizing fasciitis and streptococcal toxic shock syndrome . In addition, people may carry group A streptococci in the throat or on the skin and have no symptoms of disease.

Bacterial Skin Infection – Cellulitis and Erysipelas (Clinical Presentation, Pathology, Treatment)

Natasha Press, MD, FRCPC

What I did before

A 32 year old woman, otherwise healthy, presented with a spider-bite. On exam, she had a tender abscess on her buttock. It was associated with some surrounding cellulitis but no fever or other systemic features. I recommended incision and drainage, but she wasnt keen on it, so I gave her a 7-day prescription for cephalexin 500 mg po qid.

What changed my practice

The woman returned to the office 1 week later. The abscess had increased in size and another one had appeared on her labia. She was in significant discomfort and reported no improvement with the cephalexin. Incision and drainage of her abscesses were done, and the culture result from the swab showed community-associated methicillin resistant Staphylococcus aureus . This patient did not improve because her abscesses were caused by ca-MRSA which is resistant to cephalexin and other beta-lactam antibiotics. As well, an incision and drainage should have been done when she initially presented.

Abscesses caused by ca-MRSA are often multiple, appearing on the buttock and groin, as well as other parts of the body. Treatment includes incision and drainage, with the addition of antibiotics if the abscess is large or there is surrounding cellulitis, incomplete drainage, or fever Oral antibiotics effective against ca-MRSA usually include septra, doxycycline, and clindamycin.

What I do now

  • Initiate empiric antibiotics which cover Group A Strep AND ca-MRSA

    What Are Bacterial Skin Infections

    A bacterial skin infection can be treated with antibiotics and other topical or oral medications. A bacterial skin infection is a painful and itchy inflammation of the skin, caused by bacteria. Most often, these infections happen on the arms or legs, but you can get them anywhere on the body. If the infection gets bad enough, you may even need to be treated in a hospital. A bacterial skin infection is a type of infection that can occur on the skin.

    It usually affects the area around the mouth and eyes and may cause redness, painful sensations, and swelling. Bacterial skin infections are a type of infection that is caused by a bacterial or yeast infection that affects your skin, causing redness, swelling and other symptoms. While they may be painful and even embarrassing, they should not be taken lightly as they can cause long-term damage if left untreated.

    Generalization Of The Inflammatory Process

    A local pathological process without treatment often acquires a generalized character. A large number of rash elements with abundant exudation and the formation of grayish serous crusts appear everywhere on the skin. The red border of the lips, the mucous membranes of the mouth, nose, and eyes are affected. Diffuse foci heal with abundant peeling at the site of erosion, new vesicles and streptococcal impetigo flickens can form along the periphery.

    What Causes Group A Streptococcal Infection

    Group A streptococcal infection is caused by bacteria that commonly exist on the skin and in the throat, including among many healthy people. Up to 1 in 3 people with group A streptococcal can carry the bacteria on their bodies without it causing any disease or without their experiencing any symptoms at all.

    However, people who carry group A streptococcus can also spread the infection by coughing and sneezing droplets that contain the bacteria, or by direct skin contact. For example, if you are in close contact with someone with group A streptococcal bacteria, you may become infected if you:

    • breathe in droplets from their cough or sneeze
    • touch something with droplets on it and then touch your mouth or nose
    • drink from their glass or eat with their cutlery
    • touch their infected skin sores

    Can Invasive Group A Streptococcal Disease Be Treated

    Principles and Practices of Adequate Antibiotic Therapy

    Group A streptococcus bacteria can be treated with common, inexpensive antibiotics. Penicillin is the drug of choice for both mild and severe disease. For penicillin-allergic patients with mild illness, erythromycin can be used, although occasional resistance has been seen. Clindamycin may be used to treat penicillin-allergic patients with more severe illness and can be added to the treatment in cases of necrotizing fasciitis or STSS. Certain other antibiotics also are effective. In addition to antibiotics, supportive care in an intensive care unit and sometimes surgery are necessary with these diseases. Early treatment may reduce the risk of death although, unfortunately, even appropriate therapy does not prevent death in every case.

    What Can Be Done To Help Prevent Invasive Group A Streptococcal Infections

    The spread of all types of group A streptococcal infections may be reduced by good hand washing, especially after coughing and sneezing, before and after preparing foods and before eating. Persons with sore throats should be seen by a physician who can perform tests to find out whether it is strep throat if so, one should stay home from work, school or daycare for 24 hours or more after taking an antibiotic. All wounds should be kept clean. Wounds should be watched for possible signs of infection which include increasing redness, swelling and pain at the wound site. If these signs occur, especially in a person who also has a fever, consult a doctor immediately.

    Predisposition To Infection: Neutropenia

    Understanding Cellulitis: Skin and Soft Tissue Infections

    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 .

    The majority of minor staph skin infections may be treated at home. Soak the afflicted region with warm water or cover it with warm, damp washcloths. Apply a heating pad or a hot water bottle to the skin three or four times a day for roughly 20 minutes. If your doctor recommends it, apply antibiotic ointment. Otherwise, skip the medicine and wait it out.

    If the skin infection does not improve within a few days, see a dermatologist.

    What Is The Best Antibiotic For A Bacterial Infection

    Bacterial infections are treated with antibiotics such as amoxicillin, erythromycin and ciprofloxacin. There are many different types of antibiotic, with different ways of working the choice depends on the type of infection you have. Fungi commonly cause skin infections such as athletes foot and ringworm.

    How To Manage Recurrent Skin Infections

    Recurrent cellulitis is extremely challenging. Each repeated episode of cellulitis can cause inflammation and disruption of the lymphatic system and subsequent lymphoedema. The affected limb is subsequently more prone to infection and a vicious cycle of cellulitis and limb swelling is established.

    Treating the underlying cause of infection is the most important step in management. In cases of chronic lymphoedema and venous stasis, compression of the affected limb by bandaging or stockings helps to increase venous return and contractility of the lymphatic ducts, therefore decreasing swelling and cellulitis. Further supportive measures such as elevation of the limb may also confer symptomatic relief. For example in cellulitis of the leg, raising the foot higher than the hip with supportive cushions helps to reduce swelling and pain. Prophylactic long-term suppressive antibiotics offer symptomatic benefit and costbenefit in cases of recurrent streptococcal cellulitis.6,7 Options include twice-daily oral penicillin or cephalexin.

    For recurrent staphylococcal infections, decolonisation measures should be considered .8 In difficult cases of recurrent infections despite prophylactic antibiotics, expert consultation with an infectious disease specialist is recommended.

    What Is Group A Streptococcal Infection

    Sore throat

    Group A streptococcus, also known by the abbreviation GAS, is a type of bacteria often found in the throat and on the skin. Group A streptococcal infections commonly cause sore throats, also known as strep throat. This type of bacteria can be the cause of a rash sometimes known as scarlet fever and skin infections such as impetigo and cellulitis.

    In rare cases the bacteria can also cause a severe, life-threatening infection known as invasive group A streptococcal disease . Two of the most severe forms of iGAS are necrotising fasciitis and streptococcal toxic shock syndrome.

    In some people, a group A streptococcus infection can lead to serious complications that can harm the heart or kidneys .

    Anyone can develop group A streptococcal disease, but people who are most at risk include:

    • children under 5 years of age, especially infants
    • older people over 65 years of age
    • people with poor access to hygiene facilities
    • people who live or spend time in crowded conditions
    • people with weak immune systems or chronic illnesses

    Children are more likely to become infected because they tend to be less aware of hygiene rules than adults. They also generally spend more time in crowded environments such as schools and play in close physical contact.

    What Are Streptococcal Skin Infections

    Streptococcus bacteria can infect the skin or throat. In the case of the former, they cause skin infections such as cellulitis or impetigo. Although most streptococcal skin infections are mild, they can occasionally develop into more serious illnesses.

    Here are some terms that can help you understand streptococcal skin infections:

    • Bacteria: Microorganisms that invade the body and can cause illness.
    • Antibiotics: Medicines that kill bacteria in the body.

    Interactions With Other Drugs

    These antibiotics from streptococci exhibit the following drug interactions:

    Imipenem and Meropenem should not be used concomitantly with drugs that can damage the liver or worsen its kidney function.

    Clindamycin differs incompatibility with the antibiotics of the aminoglycoside group, hypnotics and sedatives, calcium gluconate and magnesium sulfate, as well as with vitamins B6, B9, B12.

    The activity of the drug with Cefpirum potentiates the simultaneous use of antibiotics of other groups . Also, its combination with antitumor agents, immunosuppressors, drugs for the treatment of tuberculosis, diuretics of the loop type should be avoided.

    Amoxiclav reduces blood coagulability and the reliability of hormonal contraceptives.

    Top 10 List Of Common Infections Treated With Antibiotics

    Most antibiotics fall into their individual antibiotic classes. An antibiotic class is a grouping of different drugs that have similar chemical and pharmacologic properties. Their chemical structures may look comparable, and drugs within the same class may kill the same or related bacteria.

    However, it is important not to use an antibiotic for an infection unless your doctor specifically prescribes it, even if its in the same class as another drug you were previously prescribed. Antibiotics are specific for the kind of bacteria they kill. Plus, you would need a full treatment regimen to effectively cure your infection, so dont use or give away leftover antibiotics.

    Why Does Invasive Group A Streptococcal Disease Occur

    Introduction to Impetigo | Infection, Subtypes and Treatment

    Invasive group A streptococcal infections occur when the bacteria gets past the defenses of the person who is infected. This may occur when a person has sores or other breaks in the skin that allow the bacteria to get into the tissue. Health conditions that decrease a person’s immunity to infection also make invasive disease more likely. In addition, there are certain strains of GAS that are more likely to cause severe disease than others. The reason why some strains will cause more severe illness is not totally clear but may involve the production of substances that cause shock and organ damage and of enzymes that cause tissue destruction.
