Improving access to these tests is a key step in reducing deaths from cryptococcal meningitis. At approximately the same time, the incidence of cryptococcal infections rose dramatically, due in large part to the explosion of the AIDS epidemic around the world and the use of more potent immunosuppressive agents by increasing numbers of solid organ transplant recipients [4]. A 2015 Cochrane review found a nonsignificant reduction in overall mortality (relative risk [RR] = 0.90), as well as a significant reduction in severe hearing loss (RR = 0.51), any hearing loss (RR = 0.58), and short-term neurologic sequelae (RR = 0.64) with the use of dexamethasone in high-income countries.41 The number needed to treat to decrease mortality in the S. pneumoniae subgroup was 18 and the number needed to treat to prevent hearing loss was 21.38,41 There was a small increase in recurrent fever in patients given corticosteroids (number needed to harm = 16) with no worse outcome.38,41, The best evidence supports the use of dexamethasone 10 to 20 minutes before or concomitantly with antibiotic administration in the following groups: infants and children with H. influenzae type B, adults with S. pneumoniae, or patients with Mycobacterium tuberculosis without concomitant human immunodeficiency virus infection.7,8,42,45 Some evidence also shows a benefit with corticosteroids in children older than six weeks with pneumococcal meningitis.45, Because the etiology is not known at presentation, dexamethasone should be given before or at the time of initial antibiotics while awaiting the final culture results in all patients older than six weeks with suspected bacterial meningitis. Ventriculoperitoneal shunts may become secondarily infected with bacteria; however, this is an uncommon complication. Benefits and harms. This disease is rare in healthy people. Cryptococcal meningitis is a common opportunistic infection in AIDS patients, particularly in Southeast Asia and Africa. Vaccination has nearly eliminated the risk of Haemophilus influenzae and substantially reduced the rates of Neisseria meningitidis and Streptococcus pneumoniae as causes of meningitis in the developed world.10 Between 1998 and 2007, the overall annual incidence of bacterial meningitis in the United States decreased from 1 to 0.69 per 100,000 persons.1 This decrease has been most dramatic in children two months to 10 years of age, shifting the burden of disease to an older population.1 Annual incidence is still highest in neonates at 40 per 100,000, and has remained largely unchanged.1 Older patients are at highest risk of S. pneumoniae meningitis, whereas children and young adults have a higher risk of N. meningitidis meningitis.1,11 Patients older than 60 years and patients who are immunocompromised are at higher risk of Listeria monocytogenes meningitis, although rates remain low.11, Presentation can be similar for aseptic and bacterial meningitis, but patients with bacterial meningitis are generally more ill-appearing. Maintenance therapy. It is notable that, despite the relatively short time AIDS has been in existence, more data now exist on the treatment of AIDS-associated cryptococcal meningitis than on the treatment of any other form of cryptococcal infection. Drug acquisition costs are high for antifungal therapies administered for life. Bacterial meningitis droplet precautions: What to know These cookies may also be used for advertising purposes by these third parties. Taking this medication helps prevent relapses. HILLARY R. MOUNT, MD, AND SEAN D. BOYLE, DO. Patients in the amphotericin B group had significantly more relapses, more drug-related adverse events, and more bacterial infections, including bacteremia [24]. How is cryptococcal meningitis diagnosed? So, if the disease is left untreated for a long time, it can cause some serious damage to your nervous system some of which can . Owing to its inherent toxicity and difficulty of administration, it is recommended only in a salvage setting [14] (CII). According to the British Medical Bulletin, 10 to 30 percent of people with HIV-related CM die from the illness. The cause determines if it is contagious. Examination maneuvers such as Kernig sign or Brudzinski sign may not be useful to differentiate bacterial from aseptic meningitis because of variable sensitivity and specificity. Most cases of aseptic meningitis are viral and require supportive care. If your tests come back negative for CM for two weeks, your doctor will probably ask you to stop taking amphotericin B and flucytosine. Toxicity associated with use of fluconazole/flucytosine combination therapy is substantial [15]. Some of the treatment regimens currently in use have not been studied in randomized clinical trials, but rather are used on the basis of anecdotal reports or open-label phase II studies. The format of this section was changed to improve readability and accessibility. Options. In cases of extrapulmonary, non-CNS disease, resolution of lesions is the desired outcome. Patients may also present with neurological deficits, altered mental status, and seizures, indicating increased intracranial pressure (ICP). The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. Specific recommendations for the treatment of HIV-associated cryptococcal pulmonary disease are summarized in table 2. With the exception of the typical skin lesions (which mimic molluscum contagiosum) associated with disseminated cryptococcosis, history, physical examination, or routine laboratory testing cannot elicit features suggestive of cryptococcal disease. To ensure that appropriate empiric precautions are implemented always, hospitals must have systems in place to evaluate patients routinely according to these criteria as part of their preadmission and admission care. The goal of treatment is cure of the infection (CSF sterilization) and prevention of long-term CNS system sequelae, such as cranial nerve palsies, hearing loss, and blind-ness.

Youll probably also take flucytosine, another antifungal medication, while youre taking the amphotericin B. Cryptococcal antigen can be found in the body weeks before symptoms of meningitis. This is especially true in people who have AIDS. For patients with elevated baseline opening pressure, lumbar drainage should remove enough CSF to reduce the opening pressure by 50%. No laboratory or clinical test, such as serial serum or CSF cryptococcal antigen testing, is useful for monitoring for microbial relapse during the maintenance phase of treatment [31, 34]. Vaccination against the most common pathogens that cause bacterial meningitis is recommended. Intravenous antibiotics should be used to complete the full treatment course, but outpatient management can be considered in persons who are clinically improving after at least six days of therapy with reliable outpatient arrangements (i.e., intravenous access, home health care, reliable follow-up, and a safe home environment).7, Corticosteroids are traditionally used as adjunctive treatment in meningitis to reduce the inflammatory response. cryptococcal, or other .
