Pediatric Guidelines: CNS Infections - Meningitis

Acyclovir is efficacious in treating herpes simplex meningitis and can be used to treat herpes zoster meningitis. If either of these viruses is suspected or if herpes simplex encephalitis is at all suspected, most clinicians begin empiric treatment with acyclovir and, if PCR is negative for these viruses, then stop the drug Give the first dose of IV dexamethasone just before or with the first dose of antibiotics. If giving the first dose of IV dexamethasone after initial antibiotic administration, this should ideally be done within 4 hours and not more than 12 hours after starting antibiotics.

Pediatrics. 2001;108:230-238 6. Kimberlin DW Methods: One hundred and one patients with acute primary or recurrent HSV-2 meningitis were assigned to placebo (n = 51) or 0.5 g of valacyclovir twice daily (n = 50) for 1 year after initial treatment with 1 g of valacyclovir 3 times daily for 1 week in a prospective, placebo-controlled, multicenter trial. The primary outcome was time until recurrence of meningitis HSV encephalitis is generally a more indolent process than bacterial meningitis, so one day's delay in therapy probably wouldn't be catastrophic. Acyclovir is nephrotoxic and lowers the seizure threshold. Therefore, universal application of empiric acyclovir to all encephalopathic patients while awaiting an HSV PCR would cause harm

Consult DOSAGE AND ADMINISTRATION section for recommended adjustments in dosing based upon creatinine clearance There is no direct evidence for this in meningitis/encephalitis, but fever is generally harmful for neurocritically ill patients.

*Bioavailability decreases with increasing dose. In one multiple-dose, crossover study in healthy subjects (n = 23), it was shown that increases in plasma acyclovir concentrations were less than dose proportional with increasing dose, as shown in Table 2.

Genital herpes. For the treatment of first episode genital herpes, the dose of oral acyclovir is 200 mg orally five times per day, or 400 mg orally three times per day (Table 64.1).Neither higher doses of oral acyclovir nor the addition of topical acyclovir provide added benefit (Wald et al., 1994).Duration of therapy in first episode disease is 7-10 days (Anonymous, 2002)

Clinical Practice Guidelines : Meningitis and encephaliti

  1. The recommended dose is 10 mg of dexamethasone given every 6 hours for 5 days, beginning with or before the first dose of antibiotics. The dose of acyclovir for HSV encephalitis is generally 10-12.
  2. The dose of aciclovir for infusion for children aged between three months and 12 years is calculated on the basis of body surface area. Children three months of age or older with Herpes simplex (except herpes encephalitis) or Varicella zoster infections should be given aciclovir for infusion in doses of 250 mg per square metre of body surface.
  3. There are 2 types of meningococcal vaccines available in the United States: All 11 to 12 year olds should get a meningococcal conjugate vaccine, with a booster dose at 16 years old. Teens and young adults (16 through 23 year olds) also may get a serogroup B meningococcal vaccine. CDC also recommends meningococcal vaccination for other children.

Given the suspicion of meningitis/encephalitis, the patient was given intravenous acyclovir 10 mg/kg eight hourly and ceftriaxone 2 g intravenous six hourly empirically. Following deterioration of renal function, acyclovir therapy was stopped Introduction: In late 2011, a shortage of IV acyclovir led to the need to empirically substitute high-dose oral valacyclovir (HDVA) to conserve IV acyclovir for patients with confirmed herpes simplex virus (HSV) meningitis or encephalitis If the absolute neutrophil count falls below 500/mm3, decreasing the aciclovir dose or administering granulocyte colony stimulating factor (GCSF) should be considered. At the end of therapy in CNS and disseminated disease, PCR assessment of CSF should be used and treatment continued if the child remains PCR positive at this site

Neonatal meningitis is a serious medical condition in infants that is rapidly fatal if untreated.Meningitis is an inflammation of the meninges, the protective membranes of the central nervous system, is more common in the neonatal period (infants less than 44 days old) than any other time in life, and is an important cause of morbidity and mortality globally Antibiotic dose will be divided and given down both lumens in patients with double lumen catheters.

Meningitis & Encephalitis - EMCrit Projec

Meningitis is a serious inflammation of the meninges, the thin, membranous covering of the brain and the spinal cord. Meningitis is most commonly caused by infection (by bacteria, viruses, or fungi), although it can also be caused by bleeding into the meninges, cancer, diseases of the immune system, and an inflammatory response to certain types of chemotherapy or other chemical agents Aciclovir tablets and liquid. Doses will vary, depending on why you're taking aciclovir. Your doctor will tell you how much to take and how often. A single dose is generally between 200mg and 800mg, and may be lower for children. You'll usually take aciclovir 2 to 5 times a day. Try to space the doses evenly throughout the day Encephalitis is an uncommon but potentially devastating neurological syndrome with different aetiologies including direct central nervous system infection with different agents (most commonly viral) and those mediated by the immune system. Whilst there have been several recent publications and guidelines on the management of bacterial central nervous system infections in adults and children.

Multiple antiviral medications are currently being tested in the general population; their impact on preventing the potential, rare sequelae of viral meningitis has not yet been established Acute bacterial meningitis is an infection of the meninges (the system of membranes that envelops the brain and spinal cord), which often causes hearing loss. Bacterial meningitis is fatal in 5% to 40% of children and 20% to 50% of adults despite treatment with adequate antibiotics. It is caused by bacteria that usually spread from an ear or. Fungal and tuberculous meningitis require months of therapy while viral meningitis is a self-limited infection that generally does not require therapy. The one exception to this rule is meningitis due to herpes simplex. Intravenous acyclovir or valacyclovir is recommended for these cases. 1. Antibacterial agent All patients received acyclovir intravenously for 1-2 weeks resulting in full recovery, suggesting that VZV meningitis tends to be mild symptom, good response to treatment and benign prognosis. The difficulty in meningitis diagnosis is to distinguish whether it's a viral or bacterial etiology, because this is crucial for treatment decisions


People with meningitis may need to stay in hospital for a few days, and in certain cases treatment may be needed for several weeks. Even after going home, it may be a while before you feel completely back to normal. Additional treatment and long-term support may also be required if any complications of meningitis occur, such as hearing loss GA PNA DOSE FREQUENCY ≥ 37 weeks 0 - 7 days 50 mg/kg 12-hourly ≥ 37 weeks 8 - 28 days 50 mg/kg 8-hourly AND metronidazole IV* LOAD 15 mg/kg, then PMA PNA DOSE FREQUENCY 37 - < 41 weeks n/a 7.5 mg/kg 8-hourly AND gentamicin IV †† for monotherapy or if gentamicin unsuitable use piperacillin-tazobactam IV The treatment of an underlying cause, and specifically presumed ABM or herpes encephalitis, must again be initiated early using appropriate antibiotics and acyclovir in appropriate doses. The initial choice of antibiotic may need to be revised, depending on the results of bacterial/viral antigen studies and also blood, other tissue, and CSF. For neonates with HSV encephalitis, prescribe high dose intravenous aciclovir (20 mg/kg/8 h) for a minimum of 21 days; follow-up suppressive treatment with oral valaciclovir is associated with improvement in neurodevelopment outcomes.11 Adults with HSV encephalitis need a lower dose than neonates (10 mg/kg/8 h) and for 14-21 days Acyclovir may be taken with or without food. Adult oral doses for treating genital herpes are 200 mg every 4 hours (5 times daily) for 7-10 days or 400 mg three times daily for 5-10 days. Herpes Zoster ( shingles) is treated with 800 mg every 4 hours (5 times daily) for 7 to 10 days.
