Intraventricular antibiotics for bacterial meningitis in neonates

Infection of the membranes and the fluid surrounding the brain (meningitis) and of the fluid‐filled spaces in the brain (ventriculitis) may be caused by bacteria, especially gram‐negative bacteria. This type of infection is difficult to eradicate using safe doses of antibiotics given into the blood stream. In theory, intraventricular administration of antibiotics (administration of antibiotics into the fluid‐filled spaces in the centre of the brain) would produce higher antibiotic concentrations in the fluid in the brain than intravenous administration alone, and eliminate the bacteria more quickly. However, taps of the fluid‐filled spaces may cause harm as the needle has to penetrate the brain tissue. Only one trial was identified. In this trial enrolling infants with gram‐negative meningitis and ventriculitis, the use of intraventricular antibiotics in addition to intravenous antibiotics resulted in a three‐fold increased risk for mortality compared to standard treatment with intravenous antibiotics alone. Based on this result, intraventricular antibiotics should be avoided. Further trials comparing these interventions are not justified in newborn infants.

Newer, third generation cephalosporins versus conventional antibiotics for treating acute bacterial meningitis

Acute bacterial meningitis is a life‐threatening illness. Currently the evidence suggests that old and new antibiotics offer the same level of treatment. Bacteria which cause meningitis are often thought to be resistant to conventional (older) antibiotics, and so doctors often prescribe newer antibiotics (called third generation cephalosporins). Commencing treatment early is vitally important and the choice of antibiotic is often made without any knowledge of possible drug resistance. This review examined 19 studies with 1496 participants to see whether there is a difference in effectiveness between conventional and newer antibiotics. This review found no differences. Adverse effects in both approaches were similar, except for diarrhoea, which was more common in the cephalosporin group. Only three studies dealt with adults; the remaining studies recruited participants aged 15 years and younger. Therefore, we believe that the results probably pertain more to children. Conventional and newer antibiotics seem reasonable options for initial, immediate treatment. The choice may depend on availability, affordability and local policies.

Treatment of acute cryptococcal meningitis in HIV infected adults, with an emphasis on resource‐limited settings

Despite the advent and increasingly wide availability of antiretroviral therapy for people with HIV/AIDS, cryptococcal meningitis remains a significant cause of death and illness amongst individuals with HIV infection in resource‐limited settings (poor countries). The ideal way to manage cryptococcal meningitis remains unclear. The main aim of this review was to determine the best treatment for cryptococcal meningitis in resource‐limited settings. In these settings, usually only Amphotericin and fluconazole are available. The authors didn't find any suitable studies that compared these two drugs. Because Flucytosine, which works well with Amphotericin, is often not available in poor countries, policy makers and government officials should consider using this drug for HIV treatment programmes. Future research into the management of cryptococcal meningitis in resource‐limited settings should focus on the most effective use of medications that are available in these settings.
