Bacteremia usually follows a cutaneous focus of infection but may follow an upper respiratory infection. In addition, the number of children with varicella who develop GAS bacteremia has increased (26).

reported an increased incidence of GAS bacteremia in patients with varicella from 7% to 50% at their institution (26). GAS bacteremia in varicella is thought to occur secondary to a superinfected cutaneous lesion. Serotypes M1 and M3 have been most commonly isolated in patients with GAS bacteremia. Serotypes M1, M3, and M18 are more invasive and are associated with higher morbidity and mortality rates than M4 and M12, which are generally considered less virulent.

M type 1 strains produce pyrogenic exotoxins A and B, and the latter toxin also has associated proteinase activity (7).

Therapy for GAS bacteremia consists of parenterally administered penicillin .

Patients allergic to penicillin can be treated with clindamycin , vancomycin, or a first generation cephalosporin.

Pneumonia secondary to group A streptococcus is

frequently

Since the mid 1980s, the number of reports describing this association has increased. Up to 30% of patients with GAS pneumonia have a history of group A streptococcal upper respiratory tract infection (8).

Empyema develops in 40% of patients, and bacteremia in 15%. Other complications include mediastinitis, pericarditis, pneumothorax, and bronchiectasis.

However, a peritonsillar abscess may yield mixed flora as well. Needle aspiration or surgical drainage of the abscess as well as antimicrobials are usually required. Indications for needle aspiration include severe pain and trismus, difficulty swallowing, and poor response to antimicrobials alone.

Patients can be treated orally for 10 days with either a first generation cephalosporin such as cephalexin , clindamycin , or amoxicillin-clavulanic acid, if they appear nontoxic and can maintain adequate hydration. Some patients may require initial treatment with a parenteral antibiotic and be discharged to home on oral antibiotics to complete a 10 day course. Tonsillectomy at the time of surgical incision and drainage can provide improved drainage, prevent recurrences, and permit earlier discharge. Patients with a known allergy to cephalosporins can be treated with clindamycin. P eritonsillar Cellulitis: Occasionally, peritonsillar cellulitis occurs without development of a localized abscess. Like peritonsillar abscesses, peritonsillar

cellulitis

R etropharyngeal Abscess: Retropharyngeal abscess also occurs from direct extension of an acute pharyngitis. Causative organisms include both aerobes and anaerobes.

Therapy consists of parenterally administered antimicrobials such as a first generation cephalosporin or clindamycin . Patients who do not respond to antimicrobial therapy or who have impaired respiratory function may require surgical incision and drainage under general anesthesia.

O titis Media and Sinusitis: Otitis media and sinusitis due to group amoxicillin false positive A streptococcus normally are secondary to direct extension from a streptococcal infection occurring in the upper respiratory tract.

With persistent infection, an appropriate alternative would be amoxicillin/clavulanate .

In patients allergic to amoxicillin, erythromycin or clindamycin is an acceptable alternative.

Oral cephalosporins can be effective as well in patients who have not had immediate hypersensitivity reactions to penicillin .

U vulitis : amoxicillin for laryngitis Uvulitis can occur alone or in association with acute pharyngitis or epiglottitis (50). influenzae type b infection, recent immunization strategies have greatly decreased its incidence.

However, uvulitis can occur secondary to group A streptococcus, usually as a complication of an acute pharyngitis (50).

Parenteral therapy should be used, directed against both group A streptococcus and H. Patients can be discharged on an oral antibiotic to complete a 10 day course of therapy.

C ervical Lymphadenitis: Cervical lymphadenitis secondary to group A streptococcus infection can result from direct extension from an acute pharyngitis or direct inoculation. Since the etiologic agent is not always known, therapy is initially directed against the most common organisms, which include S. Therefore, a first generation cephalosporin, such as cephalexin , or a ?-lactamase-resistant penicillin should be given enterally for 10 days.

If the infection persists or get amoxicillin medication online the patient develops signs of systemic toxicity, parenteral antibiotics should generally be used. First generation cephalosporins such as cefazolin , nafcillin , or clindamycin are also appropriate choices.

Antimicrobial therapy should be given parenterally for 10 to 14 days (12).

Patients allergic to penicillin can be treated with a

A rthritis: Post-streptococcal reactive arthritis (PSRA) is a recognized complication of group A streptococcal infections. Antibiotic therapy aimed at the underlying focus of infection is generally all that is required.

However, anti-inflammatory drugs may aid patient comfort.

Of concern, is the risk that a subset of patients with PSRA may develop rheumatic heart disease. This has led some to suggest that patients with PSRA, like patients who have had ARF, may require antimicrobial prophylaxis to prevent the occurrence of rheumatic heart disease (20). It has been recommended that these patients receive prophylaxis for 1 year, and then if no evidence amoxicillin 125mg 5ml for babies of rheumatic heart disease develops, prophylaxis could be discontinued (20).

Septic arthritis secondary to group A streptococcal infection can result from direct inoculation or bacteremic spread. Therapy consists of parenteral antibiotics given for 10 to 14 days.

Choices include a third generation cephalosporin, such as ceftriaxone and cefotaxime , or beta lactams such as nafcillin or penicillin . In addition, surgical drainage of purulent material from the joint space is required.

E ndocarditis: Endocarditis due to group A streptococcus was relatively common during the preantibiotic era.

Therapy

Patients with amoxicillin for sepsis known GAS endocarditis have been treated

successfully

O steomyelitis : Like septic arthritis, osteomyelitis secondary to group A streptococcal infection is known, but rare. Therapy consists of appropriate antimicrobials given parenterally to control the infection.

If group A streptococcus has been identified as the etiologic agent, penicillin can be used. Patients allergic to penicillin can be treated with clindamycin , vancomycin, or cefazolin .

L iver Abscess: Liver abscesses secondary to group A streptococcal infection generally result from hematogenous spread.

Therapy consists of long term parenterally administered penicillin and surgical drainage. Initially, until an etiologic agent has been determined, a combination of a penicillinase-resistant penicillin, such as

nafcillin

Treatment should consist of 2 to 4 weeks of parenterally administered

antibiotics

A cute Rheumatic Fever: Treatment of patients with acute rheumatic fever is generally directed toward decreasing acute inflammation, decreasing fever and toxicity, controlling cardiac failure, preventing episodes of recurrent ARF after significant streptococcal upper respiratory tract infections, and preventing rheumatic heart disease. The mainstays of treatment are salicylates and corticosteroids.

Neither of these agents prevents or modifies the development of rheumatic heart disease. Patients clinically diagnosed with ARF who have not received antimicrobial therapy for a recent episode of GAS pharyngitis

should
