Discussion of treatments for Meningococcal disease:

Meningococcal Disease (General): DBMD (Excerpt)

Bacterial meningitis can be treated with a number of effective antibiotics. It is important, however, that treatment be started early in the course of the disease. Appropriate antibiotic treatment of most common types of bacterial meningitis should reduce the risk of dying from meningitis to below 15%, although the risk is higher among the elderly. (Source: excerpt from Meningococcal Disease (General): DBMD)

Meningococcal Disease (General): DBMD (Excerpt)

People who qualify as close contacts of a person with meningitis caused by N. meningitidis should receive antibiotics to prevent them from getting the disease. (Source: excerpt from Meningococcal Disease (General): DBMD)

Brudzinski's sign: Emergency interventions
(Handbook of Signs & Symptoms (Third Edition))

If the patient is alert, ask him about headache, neck pain, nausea, and vision disturbances (blurred or double vision and photophobia) — all indications of increased intracranial pressure (ICP). Next, observe the patient for signs and symptoms of increased ICP, such as an altered level of consciousness (LOC) (restlessness, irritability, confusion, lethargy, personality changes, and coma), pupillary changes, bradycardia, widened pulse pressure, irregular respiratory patterns (Cheyne-Stokes or Kussmaul's respirations), vomiting, and moderate fever.

Keep artificial airways, intubation equipment, a handheld resuscitation bag, and suction equipment on hand because the patient's condition may suddenly deteriorate. Elevate the head of his bed 30 to 60 degrees to promote venous drainage. Administer an osmotic diuretic, such as mannitol, to reduce cerebral edema.

Monitor ICP and be alert for ICP that continues to rise. You may have to provide mechanical ventilation and administer a barbiturate and additional doses of a diuretic. Also, cerebrospinal fluid (CSF) may have to be drained.

Headache: Treatment
(Professional Guide to Diseases (Eighth Edition))

Depending on the type of headache, analgesics — ranging from aspirin to codeine or meperidine — may provide symptomatic relief. Other measures include identification and elimination of causative factors and, possibly, psychotherapy for headaches caused by emotional stress. Chronic tension headaches may also require muscle relaxants.

For migraine headaches, ergotamine alone or with caffeine may be an effective treatment. The Food and Drug Administration allows labeling of various analgesic preparations that include caffeine to state that they’re for the treatment of migraine headaches. Remember that these medications can’t be taken by pregnant women because they stimulate uterine contractions. These drugs and others, such as metoclopramide or naproxen, work best when taken early in the course of an attack. If nausea and vomiting make oral administration impossible, drugs may be given as rectal suppositories.

Drugs in the class of sumatriptan are considered by many clinicians to be the drug of choice for acute migraine attacks or cluster headaches. Drugs that can help prevent migraine headaches include antidepressants (such as nortriptyline or fluoxetine), beta blockers (propranolol), and calcium-channel blockers (verapamil). Corticosteroids provide short-term relief for some patients with cluster headaches.

Meningococcal infections: Treatment
(Professional Guide to Diseases (Eighth Edition))

As soon as meningococcal infection is suspected, treatment begins with high doses of aqueous penicillin G, ampicillin, or ceph-alosporins such as ceftriaxone; or, for the patient who is allergic to penicillin, I.V. chloramphenicol. Therapy may also include mannitol for cerebral edema, I.V. heparin for DIC, dopamine for shock, and digoxin and a diuretic if heart failure develops. Supportive measures include fluid and electrolyte maintenance, ventilation (maintenance of a patent airway and oxygen, if necessary), insertion of an arterial or central venous pressure (CVP) line to monitor cardiovascular status, and bed rest.

Prophylaxis with ciprofloxacin or rifampin aids health care personnel who work in close contact with the patient, such as those administering cardiopulmonary resuscitation or assisting with intubation or suctioning without wearing a surgical mask.

Vitamin C deficiency: Treatment
(Professional Guide to Diseases (Eighth Edition))

Because scurvy is potentially fatal, treatment begins immediately to restore adequate vitamin C intake by daily doses of 100 to 200 mg vitamin C in synthetic form or in orange juice in mild disease and by doses as high as 500 mg/day in severe disease. Symptoms usually subside in 2 to 3 days; hemorrhages and bone disorders, in 2 to 3 weeks.

To prevent vitamin C deficiency, patients unable or unwilling to consume foods rich in vitamin C or those facing surgery should take daily supplements of ascorbic acid. The recommended daily allowance is 60 mg/day. Vitamin C supplementation may also prevent this deficiency in recently weaned infants or those drinking formula not fortified with vitamin C.

Encephalitis: Treatment
(Handbook of Diseases)

The antiviral agent acyclovir is effective only against herpes encephalitis. Treatment of all other forms of encephalitis is entirely supportive.

Drug therapy includes phenytoin or another anticonvulsant, usually given I.V.; glucocorticoids to reduce cerebral inflammation and edema; furosemide or mannitol to reduce cerebral swelling; sedatives for restlessness; and aspirin or acetaminophen to relieve headache and reduce fever.

Other supportive measures include adequate fluid and electrolyte intake to prevent dehydration and antibiotics for an associated infection such as pneumonia. Isolation is unnecessary.

Headache: Treatment
(Handbook of Diseases)

Depending on the type of headache, treatment interventions range from relaxation techniques, massage, and biofeedback to pharmacologic agents. Tricyclic antidepressants, beta-adrenergic blockers, and anticonvulsants may be prescribed for headache prevention; nonsteroidal anti-inflammatory drugs (NSAIDs), combination NSAIDs with caffeine, ergotamines, and dopamine antagonists  may be used for abortive measures. Narcotic agents are generally avoided or may be limited to twice weekly.

Abortive therapy using the synthetic form of serotonin (sumatriptan) is available in an oral form and as a nasal spray and can easily be carried for immediate use.

Other measures include identification and elimination of causative factors, stressors, or stimuli that might trigger an attack such as in the migraine-type headache. Diet history and examination of lifestyle patterns may help identify causative agents.

Assure coverage for resistantStreptococcus pneumoniae with vancomycin if there is a concernfor meningitis: Management of Bacterial Meningitis
(Avoiding Common Pediatric Errors)

The broad-spectrum cephalosporins, cefotaxime and ceftriaxone, have traditionally been used as standard therapy for bacterial meningitis in infants and children. However, in the past decade, penicillin-and cephalosporin- resistant pneumococcal meningitis has been reported. In fact, cultures of cerebrospinal fluid (CSF) were positive for 3 to 14 days after the initiation of therapy. Therefore, in an attempt to identify an effective therapy, several antibiotic regimens including vancomycin, chloramphenicol, rifampin, erythromycin, and imipenem, alone and in combination were given to patients to identify an ideal anti–pneumococcal meningitis regimen.

Researchers concluded that on the basis of data from the pneumococcal meningitis models and limited clinical experience, it was impossible to make a single recommendation for initial empiric treatment that would be suitable forallpatientswithsuspectedorprovenpneumococcalmeningitis.However, the following guidelines could be considered in managing such patients:
• Physicians should be aware of the S. pneumoniae susceptibility patterns in their area and request their hospital laboratories to perform dilution susceptibility tests on any pneumococcal isolates recovered from usually sterile body sites.
• Because penicillin-resistant pneumococci have been identified in many areas of the United States, initial empiric therapy for bacterial meningitis should be based on the possibility that it is the etiology of the patient's illness. The recommended therapy is therefore ceftriaxone or cefotaxime and vancomycin (60 mg/kg/day divided in four doses), in addition to dexamethasone.
• A repeat lumbar puncture in patients with pneumococcal meningitis to document eradication of the pathogen should be performed 24 to 36 hours after the start of therapy, primarily in patients in whom the organism is cephalosporin resistant.
• Alteration of the initial antimicrobial regimen should be based on the clinical response of the patient and on the results of the CSF culture and susceptibility studies from the second lumbar puncture. In the event that the patients' clinical condition has worsened or that the follow-up Gram- stained smear or culture of CSF indicates failure to substantially reduce or eradicate the organism, substitution of rifampin for vancomycin in the therapeutic regimen is recommended.
• Patients without complications should be treated for a minimum of 10 days.

Meningitis: Management
(Pediatric Infectious Disease)

Empiric Therapy for Bacterial Meningitis

When faced with a patient with presumed bacterial meningitis, it is optimal to start appropriate antibiotics as early as possible. The “Gram stain game” can help in this decision. The following are the major pathogens of pediatric bacterial meningitis.

1. Streptococcus agalactiae: group B streptococcus. A gram-positive coccus, group B streptococcus is a common cause of neonatal meningitis. Up to one half of women are colonized with S. agalactiae in the genital tract; neonates become colonized at the time of delivery. A certain percentage of these neonates then become bacteremic, which can result in CSF infection. Therapy is with ampicillin and gentamicin.

2. Streptococcus pneumoniae. Another gram-positive coccus, this is the most common cause of infant and toddler meningitis. The mechanism is similar to that of group B streptococcus, whereby colonizing bacteria entering the bloodstream with subsequent infection of the CSF.

3. Neisseria meningitidis. A gram-negative diplococcus, this can cause rapid onset of meningitis, septic shock, and death. Septic shock associated with N. meningitidis is often associated with rapid onset of petechial and purpuric lesions. Therapy is with a third-generation cephalosporin or intravenous penicillin.

4. Listeria monocytogenes. A gram-positive rod, this organism is ubiquitous in the environment and commonly found in unpasteurized food products. Meningitis usually occurs in the neonatal period and in immunocompromised patients. This is the one cause of bacterial meningitis not sensitive to the third-generation cephalosporins. Ampicillin is the drug of choice, used in combination with gentamycin. For patients who cannot tolerate ampicillin, intravenous trimethoprim-sulfamethoxazole is recommended as the second choice. Vancomycin may be a successful alternative antibiotic, although treatment failures have also been reported.

5. Haemophilus influenzae (type b). Before the development of the conjugate vaccine, this gram-negative coccobacillus frequently caused invasive disease. Pediatricians rarely encounter type b H. influenzae meningitis in unvaccinated populations. There are increasing reports of nontypeable Haemophilus causing invasive disease, including meningitis. Treatment is with a third-generation cephalosporin; ampicillin can be used if the causative bacteria are β-lactamase negative.

Special Considerations: Treatment of Streptococcus pneumoniae

The most common cause of infant and toddler meningitis remains S. pneumoniae, although this may ultimately change owing to the recent addition of the conjugate vaccine to primary immunization series.

Resistance of S. pneumoniae. One of the major issues in the treatment of pneumococcal meningitis is the increasing resistance to penicillin and cephalosporins. Resistance is mediated by alterations in penicillin-binding proteins. This increases the minimal inhibitory concentration (MIC) to both these antibiotics; that is, increased concentrations of antibiotic are needed to inhibit growth of bacteria. The problem faced with treating meningitis in the context of increasing MIC is as follows:

The breakpoint is the highest MIC at which an organism is defined as sensitive to a given drug. The desire to achieve a CSF concentration of 10 times the MIC explains the breakpoints for penicillin and third-generation cephalosporins for the treatment of S. pneumoniae meningitis. The maximal concentration of penicillin obtained in the CSF is about 1.0 µg/mL. The breakpoint for the use of penicillin in pneumococcal meningitis is 0.06 µg/mL; any MIC to penicillin of an infecting pneumococcus greater than this does not guarantee a concentration 10 times the MIC. The maximal concentration for a third-generation cephalosporin in the CSF is about 5.0 µg/mL. The breakpoint for cefotaxime or ceftriaxone is 0.5 µg/mL; if the MIC is greater than 0.5, a concentration in the spinal fluid of 10 times the MIC cannot be ensured.

Rates of resistance vary from community to community. Rates of S. pneumoniae with an MIC to penicillin greater than 0.1 µg/mL can be as high as 75%. Rates of pneumococcus with an MIC to a third-generation cephalosporin greater than 0.5 µg/mL can approach 20%. These numbers may increase as antibiotic overuse persists. It is for this reason that empiric therapy for presumed pneumococcal meningitis includes vancomycin (15 mg/kg given intravenously every 6 hours) and a third-generation cephalosporin. All pneumococcal isolates from the CSF should be tested for MIC to penicillin and third-generation cephalosporins. After specific MICs are available, therapy can be tailored appropriately.

There is little experience, although justifiable concern, in the management of children with pneumococcal meningitis in which the isolated bacteria has an MIC to cefotaxime or ceftriaxone greater than 2.0 µg/mL. In those cases, treatment with both vancomycin and a third-generation cephalosporin is recommended. The addition of rifampin, 20 mg/kg in two divided doses, should also be considered.

Meropenem is a new antibiotic that has excellent gram-negative coverage and good CSF penetration. Although approved for children 3 months of age or older with penicillin-susceptible pneumococcal meningitis, there is little clinical experience with this drug in resistant pneumococcal isolates. In the coming years, more data regarding meropenem in the treatment of resistant pneumococcal meningitis will be available.

Steroid Therapy for Bacterial Meningitis

During the past decade, increasing attention has been given to adjunctive treatment for bacterial meningitis. It is recognized that bacterial meningitis is a disorder of intense inflammation and that this inflammation can result in substantial morbidity, primarily in the form of hearing loss. For patients with H. influenzae type B meningitis, dexamethasone is recommended. The dose is 0.15 mg/kg of dexamethasone every 6 hours for 4 days.

The use of steroids in pneumococcal meningitis is more controversial. A major concern is a possible decrease in antibiotic concentration in the CSF when steroids are given. In animal models, vancomycin concentration was altered up to 75% when concurrent steroids were used. The few clinical trials performed have not shown CSF differences in vancomycin and cefotaxime concentrations in the presence of dexamethasone. Two retrospective studies regarding outcome in patients with resistant pneumococcal meningitis receiving dexamethasone have been published, reaching different conclusions. In a small number of children with bacterial meningitis who received both vancomycin and dexamethasone, vancomycin levels in the CSF were comparable to those measured in children who receive vancomycin without dexamethasone. At this point, the opinion of the American Academy of Pediatrics is that the clinician needs to evaluate each case individually, weighing risks and benefits of steroid use.
