What antibiotics are used to treat Neisseria meningitidis?
Meningococcal infections are usually treated with penicillin, ampicillin, or a combination of penicillin and chloramphenicol. Isolates of Neisseria meningitidis with increased levels of resistance to penicillin have been reported in the last few years, particularly from Spain and the United Kingdom (17, 20).
What is the drug of choice for meningitis?
Penicillin is the drug of choice for the treatment of meningococcal meningitis and septicemia. Chemoprophylactic antimicrobials most commonly used to eradicate meningococci include rifampin, quinolones (eg, ciprofloxacin), ceftriaxone. Also included in this class are minocycline and spiramycin.
What Gram-negative Diplococci causes meningitis?
Acinetobacter baumannii is now the most common Gram-negative bacterium causing Gram-negative bacillary meningitis in the neurosurgical setting in parts of Europe, followed by Klebsiella pneumoniae [5,6].
What is the first line treatment for meningitis?
Acute bacterial meningitis must be treated immediately with intravenous antibiotics and sometimes corticosteroids. This helps to ensure recovery and reduce the risk of complications, such as brain swelling and seizures. The antibiotic or combination of antibiotics depends on the type of bacteria causing the infection.
Does amoxicillin cover Neisseria meningitidis?
With such low resistance rates, penicillin remained the drug of choice for the initial treatment of patients 16–60 years old with meningitis predominantly caused by S. pneumoniae and N. meningitidis….Table 1.
|Patient group .||Recommended antibiotics .|
|Age >60 years||amoxicillin and third generation cephalosporin|
Does ceftriaxone cover Neisseria meningitidis?
Antimicrobial therapy is the cornerstone of meningococcal disease management. Expanded-spectrum cephalosporins (ceftriaxone and cefotaxime) are widely accepted antimicrobials for the treatment of patients suspected of having meningococcal disease (1, 5).
Why is Vanco used for meningitis?
Treatment of meningitis with vancomycin has been effective in clinical situations that precluded the use of the commonly administered agents, i.e., in infections due to resistant strains or to unusual organisms, in patients allergic to penicillin, and in patients for whom therapy with a first-choice antibiotic has …
Why is dexamethasone given before antibiotics in meningitis?
Dexamethasone reduces morbidity and mortality in bacterial meningitis by blunting the inflammatory response secondary to bacterial lysis, which frequently causes detrimental physiologic effects. Dexamethasone should be given prior (20 minutes before) or concurrently with antibiotics.
Which antibiotics treat gram-negative bacteria?
Fourth-generation cephalosporins such as cefepime, extended-spectrum β-lactamase inhibitor penicillins (piperacillin/tazobactam, ticarcillin/clavulanate) and most importantly the carbapenems (imipenem/cilastatin, meropenem, ertapenem) provide important tools in killing Gram-negative infections.
Does meropenem penetrate CNS?
Meropenem demonstrated poor penetration into CSF, with a median CSF/serum ratio of 9 % and high interindividual pharmacokinetic variability.
What does Vanco cover in meningitis?
The addition of vancomycin was implemented in 1997 to provide coverage for ceftriaxone-nonsusceptible (ceftriaxone or cefotaxime minimum inhibitory concentration, ≥1 μg/mL) S pneumoniae isolates that were associated with ceftriaxone treatment failures.
Will amoxicillin treat bacterial meningitis?
Thus, intravenous amoxicillin sodium provided therapy for bacterial meningitis comparable to that of ampicillin in this limited case-control study.
