Mesenteric Lymphadenitis Medication

Antibiotics are often started empirically in moderately to severely ill patients, using broad-spectrum antibiotics intended to cover the commonly associated pathogens. Antibiotic treatment should then be adjusted based on the sensitivity of the isolated pathogen. Treatment duration is variable based on the cause and severity of illness. For uncomplicated cases, antibiotic treatment is not necessary.
When indicated, empiric antimicrobial therapy must be comprehensive and should cover the likely pathogens in the context of the clinical setting. Given the predominance of Y enterocolitica, initial antibiotic selection from trimethoprim-sulfamethoxazole (TMP-SMX), third-generation cephalosporins, fluoroquinolones, aminoglycosides, and doxycycline should be considered. These agents provide broad coverage for enteric pathogens.
Imidazole ring-based antibiotic active against various anaerobic bacteria and protozoa. Exerts a bactericidal effect by inhibiting protein synthesis. Used in combination with other antimicrobial agents (except for Clostridium difficile enterocolitis).
Lincosamide used for treatment of serious skin and soft tissue staphylococcal infections. Also effective against aerobic and anaerobic streptococci (except enterococci). Inhibits bacterial growth, possibly by blocking dissociation of peptidyl t-RNA from ribosomes, thus causing cessation of RNA-dependent protein synthesis.
Bactericidal activity against susceptible organisms. Alternative to amoxicillin when unable to take medication orally.
Interferes with synthesis of cell wall mucopeptides during active multiplication, resulting in bactericidal activity against susceptible bacteria.
Fluoroquinolone with activity against pseudomonads, streptococci, MRSA, Staphylococcus epidermidis, and most gram-negative organisms but no activity against anaerobes. Inhibits bacterial DNA synthesis and, consequently, growth. Trovafloxacin (Trovan) overcomes many of these limitations. Continue treatment for at least 2 d (7-14 d typical) after signs and symptoms have disappeared.
For treatment of multiple organism infections in which other agents do not have wide-spectrum coverage or are contraindicated because of potential for toxicity.
Second-generation cephalosporin indicated for gram-positive cocci and gram-negative rod infections. Infections caused by cephalosporin- or penicillin-resistant gram-negative bacteria may respond to cefoxitin.
Inhibits biosynthesis of cell wall mucopeptide and is effective during stage of active growth. Antipseudomonal penicillin plus beta-lactamase inhibitor that provides coverage against most gram-positive bacteria, most gram-negative bacteria, and most anaerobes.
Drug combination of beta-lactamase inhibitor with ampicillin. Covers skin, enteric flora, and anaerobes. Not ideal for nosocomial pathogens.
