However, failing eradication, which is common in HIV disease, long-term control of infection and resolution of clinical evidence of disease are the principal goals. Cryptococcal meningitis. You can learn more about how we ensure our content is accurate and current by reading our. Objectives. Specific pathogens are more prevalent in certain age groups, but empiric coverage should cover most possible culprits. Classic symptoms of pneumonitis, including cough, fever, and sputum production, may be present, or pleural symptoms may predominate. Outcomes. Uniform success cannot be anticipated with existing therapy; however, since the mortality associated with cryptococcal meningitis can be up to 25% among persons with AIDS, the use of therapies that result in even modest levels of success are worthy. The desired outcome is continued absence of symptoms associated with cryptococcal meningitis and resolution or stabilization of cranial nerve abnormalities. Drug acquisition costs are high for antifungal therapies administered for life. Because the goal is cure following cessation of therapy, patients requiring suppressive therapy for >12 years should be considered failures. The annual incidence is unknown because of underreporting, but European studies have shown 70 cases per 100,000 children younger than one year, 5.2 cases per 100,000 children one to 14 years of age, and 7.6 per 100,000 adults.2,3 Aseptic is differentiated from bacterial meningitis if there is meningeal inflammation without signs of bacterial growth in cultures. Therefore, initial therapy with fluconazole, even among low risk patients, is discouraged (DIII). Improving access to these tests is a key step in reducing deaths from cryptococcal meningitis. Meningitis is an inflammatory process involving the meninges. Preventing relapse of cryptococcosis reduces mortality and morbidity and slows the progression of HIV disease. They help us to know which pages are the most and least popular and see how visitors move around the site. The symptoms of CM usually come on slowly. The Advisory Committee on Immunization Practices recently added a category B recommendation (individual clinical decision making) for consideration of vaccination with serogroup B vaccines in healthy patients 16 to 23 years of age (preferred age of 16 to 18 years).60,61 The serogroup B vaccines are not interchangeable, so care should be taken to ensure completion of the series with the same brand that was used for the initial dose. Patients who tests positive for cryptococcal antigen can take antifungal medication to help the body fight the early stage of the infection. Patient information: See related handout on meningitis, written by the authors of this article. Your Guide to Salmonella Meningitis and How to Spot It, Group B Streptococcal (GBS) Meningitis: Symptoms, Treatment, Outlook, and More. Your doctor will clean an area over your spine, and then theyll inject numbing medication. Costs. Repeating the LP can identify resistant pathogens, confirm the diagnosis if initial results were negative, and determine the length of treatment for neonates with a gram-negative bacterial pathogen until CSF sterilization is documented.7,47, Prognosis varies by age and etiology of meningitis. Symptoms are those of pneumonia, meningitis, or involvement of skin, bones, or viscera. In addition, anemia occurs frequently and thrombocytemia occurs occasionally (possibly as a result of exposure to heparin). If any test is positive for C. neoformans, then a CSF examination is recommended to exclude cryptococcal meningitis. CNS disease usually presents as meningitis and on rare occasions as single or multiple focal mass lesions (cryptococcomas). Additional costs are accrued for the monthly monitoring of therapies during maintenance therapy. Data Sources: The terms meningitis, bacterial meningitis, and Neisseria meningitidis were searched in PubMed, Essential Evidence Plus, and the Cochrane database. Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. For patients with more severe disease, a combination of fluconazole (400 mg/d) plus flucytosine (100150 mg/d) may be used for 10 weeks, followed by fluconazole maintenance therapy. Because CSF enterovirus polymerase chain reaction testing is more rapid than bacterial cultures, a positive test result can prompt discontinuation of antibiotic treatment, thus reducing antibiotic exposure and cost in patients admitted for suspected meningitis.34 Similarly, polymerase chain reaction testing can be used to detect West Nile virus when seasonally appropriate in areas of higher incidence. The goal of treatment is control of the infection and prevention of dissemination of disease to the CNS. Medical approaches, including the use of corticosteroids, acetazolamide, or mannitol, have not been shown to be effective in the setting of cryptococcal meningitis. The etiologies of meningitis range in severity from benign and self-limited to life-threatening with potentially severe morbidity. Indeed, few studies have been conducted that specifically evaluate outcomes among HIV-infected patients with pulmonary or non-CNS disease. These cookies allow us to count visits and traffic sources so we can measure and improve the performance of our site. Recommendations. 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]. If your doctor suspects you have CM, they will order a spinal tap. Your doctor will monitor you closely while youre on this drug to watch for nephrotoxicity (meaning the drug can be toxic to your kidneys). Additional costs are accrued for monthly monitoring of therapies associated with most of the recommended regimens. Options. Use N95 or higher respiratory protection when aerosol-generating procedure performed. However, it is also important to exclude cryptococcal meningitis in patients with seizures, bizarre behavior, confusion, progressive dementia, or unexplained fever. Antifungal medicine treats meningitis in those who have it, and can prevent meningitis in those who do not. Benefits and harms. You will be subject to the destination website's privacy policy when you follow the link. Youll probably switch to taking only fluconazole for about eight weeks. In many cases, people need to continue taking fluconazole indefinitely. Costs. Surgery should be performed for patients with persistent or refractory pulmonary or bone disease, but it is rarely needed. Recommendations.

This recommendation is extrapolated from the treatment experience of patients with HIV-associated cryptococcal meningitis [11, 13]. In the most recent large comparative study of this disease, the overall mortality was 6%; in contrast, previous treatment studies experienced mortality rates of 14%25% [11, 13]. The most troublesome toxic side effect is renal injury, including elevation of the serum creatinine, hypokalemia, hypomagnesemia, and renal tubular acidosis. 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. The primary objective of effective intracranial pressure management is the reduction of morbidity and mortality associated with cryptococcal meningitis in both HIV and HIV-negative patients. Patients should initially undergo daily lumbar punctures to maintain CSF opening pressure in the normal range. Within a few days to a few weeks of contact, an infected person may develop the following symptoms: In some cases, the infected person may experience a stiff neck and fever. Adverse effects from fluconazole monotherapy at 400 mg daily are uncommon. Sputum fungal culture, blood fungal culture, and a serum cryptococcal antigen test are appropriate laboratory studies in any HIV-infected patient with pneumonia and a CD4+ T lymphocyte count <200 cells/mL. The presence of a positive serum cryptococcal antigen titer implies deep tissue invasion and a high likelihood of disseminated disease. The Bacterial Meningitis Score has a sensitivity of 99% to 100% and a specificity of 52% to 62%, and appears to be the most specific tool available currently, although it is not widely used.2527 The score can be calculated online at http://reference.medscape.com/calculator/bacterial-meningitis-score-child. Standard Precautions Recommendations, Table 5. (2005). C. gattii is more likely to infect someone with a healthy immune system than C. neoformans. Abstract. Defining the presence of meningitis and its severity is essential; there is no adequate substitute for examination of the CSF. Objective: This narrative review provides an evidence-based summary of the current data for the emergency medicine evaluation and management of CM. The main risk of lumbar drainage occurs in the setting of a coexistent mass lesion and obstructive hydrocephalus, which is a relatively rare complication of cryptococcal disease. Dexamethasone can be discontinued after four days or earlier if the pathogen is not H. influenzae or S. pneumoniae, or if CSF findings are more consistent with aseptic meningitis.46, Repeat LP is generally not needed but should be considered to evaluate CSF parameters in persons who are not clinically improving after 48 hours of appropriate treatment. Induction therapy. This content is owned by the AAFP. Its far more common in people with HIV or AIDS patients in Sub-Saharan Africa, where people with this disease have a mortality rate thats estimated to be 50 to 70 percent. However, in patients with HIV or AIDS, the yearly incidence rate is between 2 and 7 cases per 1,000 people. To treat a Cryptococcus infection, doctors may use any of the following antifungal medications: amphotericin B (Fungizone) flucytosine (Ancobon) fluconazole (Diflucan) For a Histoplasma infection,.
