Medical approaches, including the use of corticosteroids, acetazolamide, or mannitol, have not been shown to be effective in the setting of cryptococcal meningitis. The cause determines if it is contagious. Induction therapy. Aggressive antiretroviral therapy should be administered in accordance with standards of care in the community [35]. Fungal meningitis: Causes, symptoms, treatment, and more HIV-infected patients with elevated intracranial pressure do not differ clinically from those with normal opening pressure, except that neurological manifestations of disease are more severe among those with higher pressures [21, 22]. Last medically reviewed on December 11, 2017, Meningitis is an inflammation of the fluid and membranes surrounding the brain and spinal cord. Treatment should not be delayed if there is lag time in the evaluation. Improving access to these tests is a key step in reducing deaths from cryptococcal meningitis. The etiologies of meningitis range in severity from benign and self-limited to life-threatening with potentially severe morbidity. Meningitis - Diagnosis and treatment - Mayo Clinic This is especially true in people who have AIDS. Patients who present with mild-to-moderate symptoms or who are asymptomatic with a positive culture for C. neoformans from the lung should be treated with fluconazole, 200400 mg/d for life [3, 4, 15] (AII); however, long-term follow-up studies on the duration of treatment in the era of HAART are needed. Lipid formulations of amphotericin B can be substituted for amphotericin B for patients whose renal function is impaired. 2023 Healthline Media LLC. PDF Communicable Disease Management Protocol Viral Meningitis/Encephalitis In cases where fluconazole is not an option, an acceptable alternative is itraconazole, 400 mg/d for life [9] (CII). In patients with more severe disease, amphotericin B should be used until symptoms are controlled, then an oral azole agent, preferably fluconazole, can be substituted (BIII). Cases also occur in patients with other . Aseptic meningitis is the most common form of meningitis with an annual incidence of 7.6 per 100,000 adults. Among patients with solid organ transplants, aggressive treatment of early cryptococcal disease may prevent loss of the transplanted organ. 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. Drug acquisition costs are high for antifungal therapies administered for life. HIV-negative, immunocompromised hosts should be treated in the same fashion as those with CNS disease, regardless of the site of involvement. Cryptococcal disease is an opportunistic infection that occurs primarily among people with advanced HIV disease and is an important cause of morbidity and mortality in this group. Diagnostic accuracy of Xpert MTB/RIF Ultra and culture assays to detect Mycobacterium Tuberculosis using OMNIgene-sputum processed stool among adult TB presumptive patients in Uganda. Oral fluconazole, 200 mg/d, is the most effective maintenance therapy for AIDS-associated cryptococcal meningitis [17, 24] (AI). Whether the CNS disease is associated with involvement of other body sites, treatment remains the same. 2016 Jul 14;375(2):188. doi: 10.1056/NEJMc1605205. Specific recommendations for the treatment of non-HIV-associated cryptococcal pulmonary disease are summarized in table 1. Preventing Deaths from Cryptococcal Meningitis | Fungal Diseases | CDC Your doctor will also perform a physical examination when trying to figure out if you have CM. This guideline is part of a series of updated or new guidelines from the IDSA that will appear in CID. Thank you for submitting a comment on this article. Presentation also varies in young children, with vague symptoms such as irritability, lethargy, or poor feeding.14 Arboviruses such as West Nile virus typically cause encephalitis but can present without altered mental status or focal neurologic findings.6 Similarly, HSV can cause a spectrum of disease from meningitis to life-threatening encephalitis. We characterized 110 Cryptococcus strains collected from Xiangya Hospital of Central South University in China during the 6-year study period between 2013 and 2018, and performed their antifungal susceptibility testing . These materials are intended to support cryptococcal screen-and-treat programs. Your doctor will monitor you closely while youre on this drug to watch for nephrotoxicity (meaning the drug can be toxic to your kidneys). Several treatment options exist for managing elevated intracranial pressure (table 3) including intermittent CSF drainage by means of sequential lumbar punctures, insertion of a lumbar drain, or placement of a ventriculoperitoneal shunt. Example of Safe Donning and Removal of PPE, U.S. Department of Health & Human Services, Acute diarrhea with a likely infectious cause in an incontinent or diapered patient, Contact Precautions (pediatrics and adult), Droplet Precautions for first 24 hours of antimicrobial therapy; mask and face protection for intubation, Contact Precautions for infants and children, Rash or Exanthems, Generalized, Etiology Unknown, Droplet Precautions for first 24 hours of antimicrobial therapy, Airborne plus Contact Precautions; Contact Precautions only if Herpes simplex, localized zoster in an immunocompetent host or vaccinia viruses most likely, Maculopapular with cough, coryza and fever, Cough/fever/upper lobe pulmonary infiltrate in an HIV-negative patient or a patient at low risk for human immunodeficiency virus (HIV) infection, Airborne Precautions plus Contact precautions, Cough/fever/pulmonary infiltrate in any lung location in an HIV-infected patient or a patient at high risk for HIV infection, Cough/fever/pulmonary infiltrate in any lung location in a patient with a history of recent travel (10-21 days) to countries with active outbreaks of SARS, avian influenza, Respiratory infections, particularly bronchiolitis and pneumonia, in infants and young children. Patients may also present with neurological deficits, altered mental status, and seizures, indicating increased intracranial pressure (ICP). Specific pathogens are more prevalent in certain age groups, but empiric coverage should cover most possible culprits. This combination helps treat the condition quicker. Drug acquisition costs are high for antifungal therapies administered for life. Data Sources: The terms meningitis, bacterial meningitis, and Neisseria meningitidis were searched in PubMed, Essential Evidence Plus, and the Cochrane database. The authors thank Thomas Lamarre, MD, for his input and expertise. In cases where fluconazole cannot be given, itraconazole is an acceptable, albeit less effective, alternative [9, 33] (B, I). Patients who test positive for cryptococcal antigen can take antifungal medicine. Objective: This narrative review provides an evidence-based summary of the current data for the emergency medicine evaluation and management of CM. 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. Author disclosure: No relevant financial affiliations. 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. Dexamethasone should be given before or at the time of antibiotic administration to patients older than six weeks who present with clinical features concerning for bacterial meningitis. Advanc`es in vaccination have reduced the incidence of bacterial meningitis; however, it remains a significant disease with high rates of morbidity and mortality, making its timely diagnosis and treatment an important concern.1. Benefits and harms. By far the most common presentation of cryptococcal disease is cryptococcal meningitis, which accounts for an estimated 15% of all AIDS-related deaths globally, three quarters of which are in sub-Saharan Africa. Itraconazole appears less active than fluconazole [17, 33]. Standard Precautions Recommendations, Table 5. Worldwide, nearly 152,000 new cases of cryptococcal meningitis occur each year, resulting in an estimated 112,000 deaths. While awaiting the results of imaging studies, the serum should be tested for the presence of cryptococcal polysaccharide antigen. Fifteen percent of patients in the placebo arm developed CNS relapse compared with no relapses in the fluconazole group. Toxic side effects of amphotericin B are common and include nausea, vomiting, chills, fever, and rigors, which can occur with each dose. As the overall incidence of cryptococcal disease has increased so has the number of treatment options available to treat the disease. Drug acquisition costs are high for antifungal therapies administered for 612 months. Most immunocompetent patients will be treated successfully with 6 weeks of combination therapy [1, 3] (AI); however, owing to the requirement of iv therapy for an extended period of time and the relative toxicity of the regimen, alternatives to this approach have been advocated. Cryptococcal meningitis usually presents as a subacute meningoencephalitis. However, if oral azole therapy cannot be given, or the pulmonary disease is severe or progressive, amphotericin B is recommended, 0.40.7 mg/kg/d for a total dose of 10002000 mg (BIII). Systemic complications of acute bacterial meningitis must be treated, including the following: Hypotension or shock Hypoxemia Hyponatremia (from syndrome of inappropriate antidiuretic hormone. They help us to know which pages are the most and least popular and see how visitors move around the site. Please check for further notifications by email. Drug-related toxicities and development of adverse drug-drug interactions are the principal harms of therapeutic intervention. *Infection control professionals should modify or adapt this table according to local conditions. For patients with more severe disease, treatment with amphotericin B (0.51 mg/kg/d) may be necessary for 610 weeks. Antifungal medicine treats meningitis in those who have it, and can prevent meningitis in those who do not. Lateral flow assay is a reliable, rapid, and inexpensive test that can be used on a small sample of blood or spinal fluid to detect cryptococcal antigen. Outcomes. Cryptococcus neoformans is a fungus that lives in the environment throughout the world. Ketoconazole is not effective as maintenance therapy [30] (DII). However, in people with weakened immune systems, such as those living with HIV, Cryptococcus can stay hidden in the body and later cause a serious (but not contagious) brain infection called cryptococcal meningitis. All patients should be monitored closely for evidence of elevated intracranial pressure and managed in a fashion similar to HIV-positive patients (see below). Cryptococcal Meningitis: Diagnosis and Management Update Preferred treatment options for cryptococcal disease in HIV-negative patients. Costs. For those patients receiving long-term prednisone therapy, reduction of the prednisone dosage (or its equivalent) to 10 mg/d, if possible, may result in improved outcome to antifungal therapy. Options. Owing to its inherent toxicity and difficulty of administration, this therapy is recommended only in this salvage setting [14] (CII). Drug acquisition costs are high for antifungal therapies administered for 612 months. Meningitis - Knowledge @ AMBOSS With the advent of polyene antifungal agents, particularly amphotericin B, successful outcomes were achieved in as much as 60%70% of patients with cryptococcal meningitis, depending on the status of the host at the time of presentation [1]. Recently, lipid formulations of amphotericin B have been tested in cryptococcal meningitis and may have some toxicity profile advantages over the conventional amphotericin B formulation when used alone or possibly with flucytosine [12, 29]. CDC supports various activities to reduce illness and death from cryptococcal meningitis including: CDC has developed training materials to help educate physicians, nurses, HIV/AIDS counselors, pharmacists, and patients about the diagnosis, management, and prevention of cryptococcal disease. However, this is not possible in many areas of high incidence, and it should not delay diagnosis. Combination therapy of amphotericin B and flucytosine will sterilize CSF within 2 weeks of treatment in 60%90% of patients [1, 3]. Use N95 or higher respiratory protection when aerosol-generating procedure performed. 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. 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. Cryptococcal meningitis is a fungal infection of the tissues covering the brain and spinal cord. St George's, University of London. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. 7, 8 Droplet isolation precautions should be instituted for the first 24 hours of . Placement of a ventriculoperitoneal shunt requires neurosurgical intervention with general anesthesia, which is an expensive, but potentially life-saving, procedure. Benign recurrent lymphocytic meningitis (Mollaret meningitis), Drug-induced meningitis (e.g., non-steroidal anti-inflammatory drugs, trimethoprim/sulfamethoxazole), Alternative: meropenem (Merrem IV) plus vancomycin, Adults older than 50 years or with altered cellular immunity or alcoholism, Vancomycin plus ceftriaxone plus ampicillin, Patients with basilar skull fracture or cochlear implant, Patients with penetrating trauma or post neurosurgery, History of central nervous system disease, Seizure (in the previous 30 minutes to one week), Living in a household with one or more unvaccinated or incompletely vaccinated children younger than 48 months, 20 mg per kg per day, up to 600 mg per day, for four days, Close contact (for more than eight hours) with someone with, Single intramuscular dose of 250 mg (125 mg if younger than 15 years), Contact with oral secretions of someone with, Adults: 600 mg every 12 hours for two days, Not fully effective and rare resistant isolates, Children one month or older: 10 mg per kg every 12 hours for two days, Children younger than one month: 5 mg per kg every 12 hours for two days, Previous birth to an infant with invasive, Initial dose of 5 million units intravenously, then 2.5 to 3 million units every four hours during the intrapartum period, Colonization at 35 to 37 weeks' gestation, High risk because of fever, amniotic fluid rupture for more than 18 hours, or delivery before 37 weeks' gestation, Clindamycin susceptibility must be confirmed by antimicrobial susceptibility test. You can learn more about how we ensure our content is accurate and current by reading our. However, owing to the toxicity of this regimen, it is recommended only as an alternative option for therapy [16] (CII). Cryptococcal antigen can be found in the body weeks before symptoms of meningitis. This was demonstrated in a placebo-controlled, double-blind, randomized trial evaluating the effectiveness of fluconazole for maintenance therapy after successful primary treatment with either amphotericin B alone or in combination with flucytosine in patients with AIDS [23]. Aggressive management of elevated intracranial pressure is perhaps the most important factor in reducing mortality and minimizing morbidity of acute cryptococcal meningitis. In all cases of cryptococcal meningitis, careful attention to the management of intracranial pressure is imperative to assure optimal clinical outcome. Objectives. Lumbar puncture may be performed without computed tomography of the brain if there are no risk factors for an occult intracranial abnormality. Your comment will be reviewed and published at the journal's discretion. The content is unchanged. People with advanced HIV should be tested early for cryptococcal infection. What are the symptoms of cryptococcal meningitis? Treatment with steroids has yielded mixed results in both HIV-infected and HIV-negative patients, and its impact on outcome is unclear. Also, it is optional to continue fluconazole (200 mg/d) for 612 months (BIII). Let's look at the symptoms to know. If left untreated, CM may lead to more serious symptoms, such as: Untreated, CM is fatal, especially in people with HIV or AIDS. By this definition, almost three-fourths of 221 HIV-infected patients in a recent NIAID-sponsored Mycoses Study Group trial had elevated intracranial pressure at baseline. Examination findings that may indicate meningeal irritation include a positive Kernig sign, positive Brudzinski sign, neck stiffness, and jolt accentuation of headache (i.e., worsening of headache by horizontal rotation of the head two to three times per second). It is clear that all immunocompromised patients require treatment, since they are at high risk for development of disseminated infection. Classic symptoms of pneumonitis, including cough, fever, and sputum production, may be present, or pleural symptoms may predominate. For full access to this pdf, sign in to an existing account, or purchase an annual subscription. Fever, headache, neck stiffness, and altered mental status are classic symptoms of meningitis, and a combination of two of these occurs in 95% of adults presenting with bacterial meningitis.12 However, less than one-half of patients present with all of these symptoms.12,13, Presentation varies with age. In cases of CNS mass lesions (cryptococcomas), radiographic resolution of lesions is the desired outcome. Most people who develop CM already have severely compromised immune systems. Physical examination findings have shown wide variability in their sensitivity and specificity, and are not reliable to rule out bacterial meningitis.1820 Examples of Kernig and Brudzinski tests are available at https://www.youtube.com/watch?v=Evx48zcKFDA and https://www.youtube.com/watch?v=rN-R7-hh5x4. Maintain isolation precautions as necessary with bacterial meningitis. Owing to the intense fungal burden and large amount of replication in patients with HIV disease, adjunctive steroid therapy is not recommended for HIV-infected patients (DIII). Diagnosis of meningitis is mainly based on clinical presentation and cerebrospinal fluid analysis. CSF results can be variable, and decisions about treatment with antibiotics while awaiting culture results can be challenging. Cryptococcal Meningitis: Causes, Symptoms, and Diagnosis
