cryptococcal meningitis isolation precautions

CSF examination and viral isolation or serology. We provide a complete overview, including causes, symptoms, and treatment. An 8-person subcommittee of the National Institute of Allergy and Infectious Diseases (NIAID) Mycoses Study Group evaluated available data on the treatment of cryptococcal disease. Meningitis is inflammation of the subarachnoid space, the fluid bathing the brain (between the arachnoid and the pia mater; figure above). (2017).

You can review and change the way we collect information below. Mortality remains high despite the introduction of vaccinations for common pathogens that have reduced the incidence of meningitis worldwide. Serum procalcitonin, serum C-reactive protein, and CSF lactate levels can be useful in distinguishing between aseptic and bacterial meningitis.2833 C-reactive protein has a high negative predictive value but a much lower positive predictive value.28 Procalcitonin is sensitive (96%) and specific (89% to 98%) for bacterial causes of meningitis.29,30 CSF lactate also has a high sensitivity (93% to 97%) and specificity (92% to 96%).3133 CSF latex agglutination testing for common bacterial pathogens is rapid and, if positive, can be useful in patients with negative Gram stain if LP was performed after antibiotics were administered. 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]. The presence of a positive serum cryptococcal antigen titer implies deep tissue invasion and a high likelihood of disseminated disease. The clinicians index of suspicion should be guided by the prevalence of specific conditions in the community, as well as clinical judgment. Options. Bacterial meningitis droplet precautions, such as wearing personal protective equipment (PPE) and isolating those with the disease, can reduce the spread of this disease from person to person.. While awaiting the results of imaging studies, the serum should be tested for the presence of cryptococcal polysaccharide antigen. This inflammation can produce a wide range of symptoms and, in extreme cases, cause brain damage, stroke, or even death. Endotracheal intubation (EI) is an emergency procedure that's often performed on people who are unconscious or who can't breathe on their own. The differential . Acetozolamide and mannitol have not been shown to provide any clear benefit in the management of elevated intracranial pressure resulting from cryptococcal meningitis (DIII). Amphotericin B, flucytosine, and fluconazole are antifungal medications shown to improve survival in patients with cryptococcal infections. This specific species is an emerging pathogen and is best known for the 2013 outbreak in the U.S. Pacific Northwest. Costs. Michael S. Saag, Richard J. Graybill, Robert A. Larsen, Peter G. Pappas, John R. Perfect, William G. Powderly, Jack D. Sobel, William E. Dismukes, Mycoses Study Group Cryptococcal Subproject, Practice Guidelines for the Management of Cryptococcal Disease, Clinical Infectious Diseases, Volume 30, Issue 4, April 2000, Pages 710718, https://doi.org/10.1086/313757. On the basis of experience of treating cryptococcal meningitis in HIV disease, it is reasonable to follow a similar induction, consolidation, and suppression strategy, since previous strategies reported failure rates of 15%20% with 6 weeks of treatment with combination amphotericin B/5-flucytosine [3]. Most cases are . Specific recommendations for the treatment of non-HIV-associated cryptococcal meningitis are summarized in table 1. In 2015, the Advisory Committee on Immunization Practices gave meningococcal serogroup B vaccines a category B recommendation (individual clinical decision making) for healthy patients 16 to 23 years of age (preferred age 16 to 18 years). Two types of fungus can cause cryptococcal meningitis (CM). According to the British Medical Bulletin, 10 to 30 percent of people with HIV-related CM die from the illness. Cryptococcal antigen, a biological marker that indicates a person has cryptococcal infection, can be detected in the body weeks before symptoms of meningitis appear. CM is more common in people who have compromised immune systems, such as people who have AIDS. Benefits and harms. Patients who test positive for cryptococcal antigen can take antifungal medicine. Youll receive antifungal drugs if you have CM. Appropriate antimicrobials should be given promptly if bacterial meningitis is suspected, even if the evaluation is ongoing. 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]. Indeed, few studies have been conducted that specifically evaluate outcomes among HIV-infected patients with pulmonary or non-CNS disease. 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. Copyright 2017 by the American Academy of Family Physicians. Objectives. The content is unchanged. Meningitis is an infection and inflammation of the meninges, which are the membranes that cover the brain and spinal cord. Objectives. Recommendations. 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. Ventriculoperitoneal shunts may become secondarily infected with bacteria; however, this is an uncommon complication. Objectives. As is true for other systemic mycoses, treatment of disease due to C. neoformans have improved dramatically over the last 2 decades. Beginning in the 1980s, orally bioavailable azole antifungal agents with activity against C. neoformans were introduced, in particular, itraconazole and fluconazole. Additional costs are accrued for monthly monitoring and supervision of therapies associated with most of the recommended regimens. Treatment with steroids has yielded mixed results in both HIV-infected and HIV-negative patients, and its impact on outcome is unclear. Control Management of Cases: Enteric precautions are indicated for seven days after onset, unless a non-enteroviral diagnosis is established. When flucytosine was added to amphotericin B as combination therapy, overall outcome of therapy was improved and the duration of treatment could be reduced from 10 weeks to 46 weeks, depending on the status of the host [1, 3]. 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. Focal neurological signs may reflect mass lesions. Antifungal medicine treats meningitis in those who have it, and can prevent meningitis in those who do not. Causes In most cases, cryptococcal meningitis is caused by the fungus Cryptococcus neoformans. 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. The objective of treatment is eradication of the infection and control of elevated intracranial pressure. 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. In conjunction with antiretroviral therapy, long-term maintenance antifungal therapy should be administered. The format of this section was changed to improve readability and accessibility. Cryptococcal meningitis, mainly caused by Cryptococcus neoformans/gattii species complexes, is a lethal infection in both immunosuppressive and immunocompetent populations.

Airborne plus Contact Precautions plus eye protection. Recommendations. Bacterial meningitis. Classic signs of meningeal irritation commonly are absent on physical examination, and routine laboratory assessment is rarely revealing. Prospective clinical trials and carefully conducted observational studies show that potent antiretroviral therapy reduces the incidence of opportunistic infections [2527]. Benefits and harms. For those individuals who are unable to tolerate fluconazole, itraconazole (200400 mg/day for 612 months) is an acceptable alternative. Patients are usually treated with two antifungal agents and the . If your doctor suspects you have CM, they will order a spinal tap. 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 serum cryptococcal antigen is positive in >99% of subjects with cryptococcal meningitis, usually at titers >1 : 2048 [11, 13]. This recommendation is extrapolated from the treatment experience of patients with HIV-associated cryptococcal meningitis [11, 13]. Most common causes are viral or autoimmune. People with advanced HIV should be tested early for cryptococcal infection. Fifteen percent of patients in the placebo arm developed CNS relapse compared with no relapses in the fluconazole group. Search dates: October 1, 2016, and March 13, 2017. One-fourth of the patients had opening pressures >350 mm H2O [22]. However, there are considerable side effects from flucytosine (150 mg/kg/d) when given in combination with fluconazole for 10 weeks in patients with HIV-associated cryptococcal meningitis [16]. Drug-related toxicities and development of adverse drug-drug interactions are the principal potential harms of therapeutic intervention. Bicanic T, et al. Additional costs are accrued for the biweekly monitoring of therapies during acute induction therapy and every-other-week monitoring during consolidation therapy. Meningitis is an infection and inflammation of the meninges, which are the membranes that cover the brain and spinal cord. The desired outcome is continued absence of symptoms associated with cryptococcal meningitis and resolution or stabilization of cranial nerve abnormalities. Cryptococcal meningitis pathophysiology includes brain damage. 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,. Pneumonia is thought to herald the onset of disseminated disease. Bacterial meningitis is a medical emergency that requires prompt recognition and treatment. Patients who test positive for cryptococcal antigen can take antifungal medicine. To screen people living with HIV for early cryptococcal infection and cryptococcal meningitis, healthcare facilities and laboratories must have access to the reliable tests. Costs. The relative strength of each recommendation was graded according to the type and degree of evidence available to support the recommendation, in keeping with previously published guidelines by the Infectious Diseases Society of America (IDSA). 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. For patients with more severe disease, treatment with amphotericin B (0.51 mg/kg/d) may be necessary for 610 weeks. Options. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. Recommendations. Secondary infection of the shunt with C. neoformans generally does not occur if antifungal therapy has been instituted. Drug acquisition costs are high for antifungal therapies administered for life. 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. Your doctor will clean an area over your spine, and then theyll inject numbing medication. The desired outcome is resolution of symptoms, such as cough, shortness of breath, sputum production, chest pain, fever, and resolution or stabilization of abnormalities (infiltrates, nodules, masses, etc.) Amphotericin B (0.71 mg/kg given iv daily for 2 weeks) combined with flucytosine, 100 mg/kg given orally in 4 divided doses per day, is the initial treatment of choice [11, 13, 18, 29] (AI). Although no retrospective or prospective studies have been conducted to investigate treatment options for such patients, they should probably be treated with antifungal therapy (AIII). HSV and varicella zoster viral polymerase chain reaction testing should be used in the setting of meningoencephalitis. 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. These pathogens include enterohemorrhagicEscherichia coliO157:H7,Shigella spp,hepatitis A virus, noroviruses, rotavirus,C. difficile. 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. Please check for further notifications by email. A summary of treatment recommendations for AIDS-associated cryptococcal meningitis is provided in table 2. The organism has a strong predilection for infecting the CNS; however, infection has been reported in virtually every organ in the body. Therapy with amphotericin B (0.71 mg/kg/d) for 2 weeks, followed by 810 weeks of fluconazole (400800 mg/d), is followed with 612 months of suppressive therapy with a lower dose of fluconazole (200 mg/d) (BIII). Most parenchymal lesions will respond to antifungal treatment; large (>3 cm) accessible CNS lesions may require surgery. 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. Youll need to get spinal fluid testing repeatedly during treatment. Dexamethasone should be administered to children and adults with suspected bacterial meningitis before or at the time of initiation of antibiotics.

This fungus is found in soil all over the world. 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. . (2005). Defining the presence of meningitis and its severity is essential; there is no adequate substitute for examination of the CSF. Some reports describe the successful use of flucytosine (100 mg/kg/d for 612 months) as therapy for pulmonary cryptococcal disease; however, concern about the development of resistance to flucytosine when used alone limits its use in this setting [2, 5] (DII). This disease is rare in healthy people. CSF antigen titers are higher and the India ink smear is more frequently positive among patients with elevated opening pressure than among patients with normal opening pressure. Learn about the risk factors and complications. Treatment options for cryptococcal disease in HIV-infected patients. Authors Anil A Panackal 1 , Kieren A Marr 2 , Peter R Williamson 3 Affiliations 1 National . The cause determines if it is contagious. In cases where fluconazole is not an option, an acceptable alternative is itraconazole, 400 mg/d for life [9] (CII). Immunosuppressed patients, such as solid organ transplant recipients, require more prolonged therapy [3]. Its usually found in soil that contains bird droppings. The antibiotic or combination of antibiotics depends on the type of bacteria causing the infection. In both HIV-negative and HIV-positive patients with cryptococcal meningitis, elevated intracranial pressure occurs in excess of 50% of patients [22]. Among those individuals who are unable to tolerate fluconazole, itraconazole (200400 mg/d) is an acceptable alternative. Some HIV-infected patients present with isolated cryptococcemia or a positive serum cryptococcal antigen titer (>1 : 8) without evidence of clinical disease. We avoid using tertiary references. Prolonged external lumbar drainage places patients at major risk for bacterial infection. St George's, University of London. Ebola Virus Disease for Healthcare Workers [2014]. Academic Pulmonary Sleep Medicine Physician Opportunity in Scenic Central Pennsylvania, MEDICAL MICROBIOLOGY AND CLINICAL LABORATORY MEDICINE PHYSICIAN, CLINICAL CHEMISTRY LABORATORY MEDICINE PHYSICIAN, Copyright 2023 Infectious Diseases Society of America. The choice of treatment for disease caused by Cryptococcus neoformans depends on both the anatomic sites of involvement and the host's immune status. A lumbar puncture is recommended after 2 weeks of treatment to assess the status of CSF sterilization. Management of elevated intracranial pressure in HIV-infected patients with cryptococcal disease. Aseptic meningitis is the most common form of meningitis with an annual incidence of 7.6 per 100,000 adults. All rights reserved. Surgery should be performed for patients with persistent or refractory pulmonary or bone disease, but it is rarely needed. 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. CDC twenty four seven. The most common forms of immunosuppression other than human immunodeficiency virus (HIV) include glucocorticoid therapy, biologic modifiers, the use of some tyrosine kinase inhibitors (eg, ibrutinib), solid organ transplantation, cancer (particularly hematologic malignancy), and conditions such as . It is clear that all HIV-infected patients require treatment, since they are at high risk for disseminated infection. Recommendations. Lipid formulations of amphotericin B appear beneficial and may be useful for patients with cryptococcal meningitis and renal insufficiency [12, 1821] (CII). Salmonella meningitis is a kind of bacterial meningitis that can be dangerous if not treated. Therefore, the specific treatment of choice has not been fully elucidated. For those individuals with non-CNS-isolated cryptococcemia, a positive serum cryptococcal antigen titer >1 : 8, or urinary tract or cutaneous disease, recommended treatment is oral azole therapy (fluconazole) for 36 months. Elevated intracranial pressure is defined as opening pressure >200 mm H2O, measured with the patient in a reclining (lateral decubitus) position. 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. All Rights Reserved. If left untreated, CM may lead to more serious symptoms, such as: Untreated, CM is fatal, especially in people with HIV or AIDS. 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. In selected cases, susceptibility testing of the C. neoformans isolate may be beneficial to patient management, particularly if a comparison can be determined between baseline and sequential isolates.
