Pediatric Gastroenteritis Medication

Medication Summary
Although antibiotic treatment clearly shortens the clinical illness and duration of pathogen excretion in dysentery caused by Shigella species, routine antibiotic use provides no clear advantage to treat gastroenteritis caused by Campylobacter jejuni, Yersinia enterocolitica, E coli, and Salmonella species.
Antibiotic administration may be considered for very young patients with Salmonella- caused gastroenteritis, for patients who are immunocompromised, and for patients who are systemically ill.
Evidence suggests that antibiotic treatment of enterohemorrhagic E coli infection may increase the risk for developing hemolytic uremic syndrome.
Rifaximin has excellent antibacterial activity and was approved in 2004 for the treatment for traveler's diarrhea caused by noninvasive strains of E coli.
Antibiotics
Class Summary
In cases of Shigella enteritis, antibiotic treatment provides more rapid resolution of symptoms and faster fecal shedding of the organism. Trimethoprim-sulfamethoxazole (TMP-SMZ) is the drug of choice. In uncomplicated enteritis caused by nontyphoidal Salmonella species, antibiotics have no beneficial effect and may prolong the carrier state. The role of antimicrobials to treat enteritis caused by Campylobacter species, Y enterocolitica, and E coli remains controversial. Metronidazole is the recommended medication for G lamblia.
Sulfamethoxazole and Trimethoprim (Bactrim, Cotrim, Septra)
An antibacterial combination that may be used to treat enteritis caused by susceptible strains of Shigella flexneri and Shigella sonnei when antibacterial therapy is indicated.
Metronidazole (Flagyl)
Appears to be absorbed into cells where intermediate-metabolized compounds are formed that bind DNA and inhibit protein synthesis.
Rifaximin (Xifaxan, RedActiv, Flonorm)
Nonabsorbed (< 0.4%), broad-spectrum antibiotic specific for enteric pathogens of the gastrointestinal tract (ie, Gram-positive, Gram-negative, aerobic and anaerobic). Rifampin structural analog. Binds to beta-subunit of bacterial DNA-dependent RNA polymerase, thereby inhibiting RNA synthesis. Indicated for E coli (enterotoxigenic and enteroaggregative strains) associated with travelers' diarrhea.
Vaccines
Class Summary
These agents elicit active immunization to increase resistance to infection. Vaccines consist of microorganisms or cellular components, which act as antigens. Administration of the vaccine stimulates the production of antibodies with specific protective properties.
Rotavirus vaccine (RotaTeq, Rotarix)
Currently, 2 orally administered live-virus vaccine are available.
RotaTeq contains 5 live human-bovine reassortant rotaviruses and is administered as a 3-dose regimen against G1, G2, G3, and G4 serotypes, the 4 most common rotavirus group A serotypes. It also contains attachment protein P1A (genotype P[8]).
Rotarix contains an attenuated human strain and is effective against rotavirus G1, G3, G4, and G9 strains and is administered as a 2-dose series in infants aged 6-24 wk.
