Once in the hospital, the antibiotics of choice are usually IV broad spectrum 3rd generation cephalosporins, e.g., cefotaxime or ceftriaxone. Benzylpenicillin and chloramphenicol are also effective. Supportive measures include IV fluids, oxygen, inotropic support, e.g., dopamine or dobutamine and management of raised intracranial pressure. Steroid therapy may help in some adult patients, but is unlikely to affect long term outcomes.There is some debate on which antibiotic is most effective at treating the illness. A systematic review compared two antibiotics. There was one trial: an open label (not blinded) non-inferiority trial of 510 people comparing two different types of antibiotics; ceftriaxone (in which there were 14 deaths out of 247), and chloramphenicol (12 deaths out of 256). There were no reported side effects. Both antibiotics were considered equally effective. Antibiotic choice should be based on local antibiotic resistance information. Prognosis
Complications
Complications following meningococcal disease can be divided into early and late groups. Early complications include: raised intracranial pressure, disseminated intravascular coagulation, seizures, circulatory collapse and organ failure. Later complications are: deafness, blindness, lasting neurological deficits, reduced IQ, and gangrene leading to amputations. Epidemiology
Africa
The importance of meningitis disease is as significant in Africa as HIV, TB and malaria. Cases of meningococcemia leading to severe meningoencephalitis are common among young children and the elderly. Deaths occurring in less than 24 hours are more likely during the disease epidemic seasons in Africa and Sub-Saharan Africa is hit by meningitis disease outbreaks throughout the epidemic season.
Since vaccine duration is unknown, mass select vaccinations may be the most cost-effective means for controlling the transmission of the meningococcal disease, rather than mass routine vaccination schedules. Chronic medical conditions
Persons with component deficiencies in the final common complement pathway (C3, C5-C9) are more susceptible to N. meningitidis infection than complement-satisfactory persons, and it was estimated that the risk of infection is 7000 times higher in such individuals. In addition, complement component-deficient populations frequently experience frequent meningococcal disease since their immune response to natural infection may be less complete than that of complement non-deficient persons.Inherited properdin deficiency also is related, with an increased risk of contracting meningococcal disease. Persons with functional or anatomic asplenia may not efficiently clear encapsulated Neisseria meningitidis from the bloodstream Persons with other conditions associated with immunosuppression also may be at increased risk of developing meningococcal disease. Antibiotics
An updated 2013 Cochrane review investigated the effectiveness of different antibiotics for prophylaxis against meningococcal disease and eradication of N. meningitidis particularly in people at risk of being carriers. The systematic review included 24 studies with 6,885 participants. During follow up no cases of meningococcal disease were reported and thus true antibiotic preventative measures could not be directly assessed. However, the data suggested that rifampin, ceftriaxone, ciprofloxacin and penicillin were equally effective for the eradication of N. meningitidis in potential carriers, although rifampin was associated with resistance to the antibiotic following treatment. Eighteen studies provided data on side effects and reported they were minimal but included nausea, abdominal pain, dizziness and pain at injection site.
