Meningitis is an infection of the meninges, the membranes that surround the brain and spinal cord. Outcomes. Control Management of Cases: Enteric precautions are indicated for seven days after onset, unless a non-enteroviral diagnosis is established. Whether the CNS disease is associated with involvement of other body sites, treatment remains the same. Bacterial meningitis is a medical emergency that requires prompt recognition and treatment. Three percent of fluconazole patients and 37% of placebo patients relapsed at any site. Outcomes. Thank you for taking the time to confirm your preferences. Options. Copyright 2017 by the American Academy of Family Physicians. It is necessary to carefully monitor serum electrolytes, renal function, and bone marrow function. Meningitis is an infection and inflammation of the meninges, which are the membranes that cover the brain and spinal cord. All patients should be monitored closely for evidence of elevated intracranial pressure and managed in a fashion similar to HIV-positive patients (see below). Treatment with chemoprophylactic antibiotics should be given to close contacts7,62,63 (Table 89,14,6468 ). Among HIV-infected patients with elevated CSF pressures, a poorer clinical response was noted among patients whose pressure increased between baseline and week 2 of treatment; benefit from management of intracranial pressure is inferred from reduced mortality in this population [22]. Elevated intracranial pressure is an important contributor to morbidity and mortality of cryptococcal meningitis. These essential medications are often unavailable in areas of the world where they are most needed. However, in patients with HIV or AIDS, the yearly incidence rate is between 2 and 7 cases per 1,000 people. 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). For selected patients who have responded very well to HAART, consideration might be given to discontinuing secondary antifungal prophylaxis after 1218 months of successful suppression of HIV viral replication (CIII). Drug acquisition costs are high for antifungal therapies administered for life. Worldwide, approximately 1 million new cases of cryptococcal meningitis occur each year, resulting in 625,000 deaths. 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.

Fluconazole consolidation therapy may be continued for as along as 612 months, depending on the clinical status of the patient. 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. This is not the case for all patients and can vary in older patients and those with partially treated bacterial meningitis, immunosuppression, or meningitis caused by L. monocytogenes.11 It is important to use age-adjusted values for white blood cell counts when interpreting CSF results in neonates and young infants.23 In up to 57% of children with aseptic meningitis, neutrophils predominate the CSF; therefore, cell type alone cannot be used to differentiate between aseptic and bacterial meningitis in children between 30 days and 18 years of age.24. Learn more about the signs of meningitis, and how to, There are important differences between viral, fungal, and bacterial meningitis, in terms of their severity, how common they are, and the way they are. Prospective clinical trials and carefully conducted observational studies show that potent antiretroviral therapy reduces the incidence of opportunistic infections [2527]. Before 1950, disseminated cryptococcal disease was uniformly fatal. You can review and change the way we collect information below. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. To further complicate the diagnostic process, physical examination and testing are limited in sensitivity and specificity. The study will help to identify safer and more effective drugs that target cryptococcal infections like the life-threatening meningo-encephalitis in an immunocompromised host. Aggressive management of elevated intracranial pressure is perhaps the most important factor in reducing mortality and minimizing morbidity of acute cryptococcal meningitis. In both HIV-negative and HIV-positive patients with cryptococcal meningitis, elevated intracranial pressure occurs in excess of 50% of patients [22]. This test cannot be used to rule out bacterial meningitis.7. Cryptococcal meningitis. CDC can also help provide customized resources on training and case studies for cryptococcal screening. Cryptococcal Meningitis: a Life-Threatening Brain Infection INTRODUCTION. Use eye/face protection if aerosol-generating procedure performed or contact with respiratory secretions anticipated. Drug-related toxicities and development of adverse drug-drug interactions are the principal potential harms of therapeutic intervention. Options. Costs. The treatment for cryptococcal meningitis is intravenous administration of amphotericin B; may be used with or without 5-flucytosine. Additional costs are accrued for the biweekly monitoring of therapies during acute induction therapy and every-other-week monitoring during consolidation therapy. Frontiers | Microbiological, Epidemiological, and Clinical Options. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. However, no randomized studies in these population groups have been completed in the era of triazole therapy. Combination therapy with fluconazole (400800 mg/d) and flucytosine (100 mg/kg/d in 4 divided doses) has been shown to be effective in the treatment of AIDS-associated cryptococcal meningitis [16, 29]. 2023 Healthline Media LLC. The prevention of progression to cryptococcal meningitis is the principal goal of therapy in this population. However, cryptococcal meningitis is still a major problem where HIV prevalence is high and where access to healthcare may be limited. Therefore, owing to its toxicity and difficulty with administration, amphotericin B maintenance therapy should be reserved for those patients who have had multiple relapses while receiving azole therapy or who are intolerant of the azole agents (CI). As is true for other systemic mycoses, treatment of disease due to C. neoformans have improved dramatically over the last 2 decades. Treatment with steroids has yielded mixed results in both HIV-infected and HIV-negative patients, and its impact on outcome is unclear. 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. 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. Appropriate antibiotics should be given to identified contacts within 24 hours of the patient's diagnosis and should not be given if contact occurred more than 14 days before the patient's onset of symptoms.63 Options for chemoprophylaxis are rifampin, ceftriaxone, and ciprofloxacin, although rifampin has been associated with resistant isolates.62,63, This article updates a previous article on this topic by Bamberger.9. Bicanic T, et al. Mortality remains high despite the introduction of vaccinations for common pathogens that have reduced the incidence of meningitis worldwide. Airborne plus Contact Precautions plus eye protection. Improved access to antiretroviral therapy (ART) globally has helped improve the immune systems of many HIV patients so that they arent at increased risk of cryptococcal meningitis. If your tests come back negative for CM for two weeks, your doctor will probably ask you to stop taking amphotericin B and flucytosine. Some HIV-infected patients present with isolated cryptococcemia or a positive serum cryptococcal antigen titer (>1 : 8) without evidence of clinical disease. Etiologies range in severity from benign and self-limited to life-threatening with potentially severe morbidity. Bacterial meningitis droplet precautions: What to know The goal of treatment is control of the infection and prevention of dissemination of disease to the CNS. Most of the illness and deaths are estimated to occur in resource-limited countries, among people living with HIV. Cookies used to enable you to share pages and content that you find interesting on CDC.gov through third party social networking and other websites. HSV and varicella zoster viral polymerase chain reaction testing should be used in the setting of meningoencephalitis. 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. 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. There are no controlled clinical trials describing the outcome of therapy for AIDS-related cryptococcal pneumonia (table 2). 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. More Information. This is especially true in people who have AIDS. Cryptococcus neoformans / isolation & purification* These cookies allow us to count visits and traffic sources so we can measure and improve the performance of our site. The elevated intracranial pressure in this setting is thought to be due, in part, to interference with CSF reabsorption in the arachnoid villi, caused by high levels of fungal polysaccharide antigen or excessive growth of the organism per se. Aseptic and Bacterial Meningitis: Evaluation, Treatment, and Prevention Yet, because of the potentially grave consequences of overlooking this illness, it is imperative to assess AIDS patients with pneumonia for possible fungal infection. The presence of a positive serum cryptococcal antigen titer implies deep tissue invasion and a high likelihood of disseminated disease. People who have advanced HIV infection should be tested for cryptococcal antigen. 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 prevalence of cryptococcosis in these studies was too low to provide direct evidence or confirm that antiretroviral therapy affects cryptococcal disease, but there is no biological basis to suspect that control of cryptococcosis in AIDS patients would not be improved by the use of HAART. After the 2-week period of successful induction therapy, consolidation therapy should be initiated with fluconazole (400 mg orally once daily) administered for 8 weeks or until CSF cultures are sterile [11] (AI). CDC twenty four seven. Costs. Infection Control Isolation Precautions Appendix A Clinical Syndromes or Conditions Warranting Empiric Transmission-Based Precautions in Addition to Standard Precautions Guideline for Isolation Precautions: Preventing Transmission of Infectious Agents in Healthcare Settings (2007) Appendix A: Table 2 Format Change [February 2017] Fluconazole is well-tolerated; nausea, abdominal pain, and skin rash are the most common adverse effects. Youll receive antifungal drugs if you have CM. These patients, as well as those coinfected with human immunodeficiency virus, should be managed in consultation with an infectious disease subspecialist when available. But the conditional rarely occurs in someone who has a normal immune system. Ketoconazole is generally ineffective in the treatment of cryptococcosis in HIV-infected patients and should probably be avoided [10, 30] (DII). Older patients are less likely to have headache and neck stiffness, and more likely to have altered mental status and focal neurologic deficits11,13 (Table 31113 ). The CNS disease may be associated with concurrent pneumonia or with other evidence of disseminated disease, such as focal skin lesions, but most commonly presents as solitary CNS infection without other manifestations of disease. There is little to distinguish cryptococcal pneumonia from other causes of atypical pneumonia in HIV-infected patients. Reprints or correspondence: Dr. Michael S. Saag, University of Alabama at Birmingham, 908 20th Street South, Birmingham, AL 35294-2050 (. In HIV-infected patients, evaluation of the CSF reveals minimal inflammation (frequently, few leukocytes; and normal levels of glucose and protein) but uncontrolled fungal growth in the CSF. Your doctor will clean an area over your spine, and then theyll inject numbing medication. Although all asymptomatic patients with positive cultures should be considered for treatment, many immunocompetent patients with positive sputum cultures have done well without therapy [5]. The classic triad of meningitis is fever, headache, and neck stiffness. Youll probably switch to taking only fluconazole for about eight weeks. 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 . However, it is also important to exclude cryptococcal meningitis in patients with seizures, bizarre behavior, confusion, progressive dementia, or unexplained fever. Length of treatment varies based on the pathogen identified (Table 67 ). Cryptococcal antigen can be found in the body weeks before symptoms of meningitis. Itraconazole appears less active than fluconazole [17, 33]. Because clinical findings are also unreliable, the diagnosis relies on the examination of cerebrospinal fluid obtained from lumbar puncture. If left untreated, CM may lead to more serious symptoms, such as: Untreated, CM is fatal, especially in people with HIV or AIDS. Before CSF results are available, patients with suspected bacterial meningitis should be treated with antibiotics as quickly as possible.8,22,36,37 Acyclovir should be added if there is concern for HSV meningitis or encephalitis. Specific recommendations for the treatment of non-HIV-associated cryptococcal pulmonary disease are summarized in table 1. There are a number of clinical decision tools that have been developed for use in children to help differentiate between aseptic and bacterial meningitis in the setting of pleocytosis. Most people who develop CM already have severely compromised immune systems. Although some preliminary evidence suggests lower relapse rates of opportunistic infections when patients have been successfully treated with potent antiretroviral therapy, until proven otherwise, maintenance therapy for cryptococcal meningitis should be administered for life (AI). 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]. The authors thank Thomas Lamarre, MD, for his input and expertise. 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. The differential . Opinion regarding optimal treatment was based on personal experience and information in the literature. Recommendations. Meningitis - Knowledge @ AMBOSS Cookies used to track the effectiveness of CDC public health campaigns through clickthrough data. Because the goal is cure following cessation of therapy, patients requiring suppressive therapy for >12 years should be considered failures. Additional costs are accrued for monthly monitoring and supervision of therapies associated with most of the recommended regimens. Update: Recommendations for healthcare workers can be found at Ebola For Clinicians. To reduce mortality from cryptococcal infection, CD4 testingis also needed to identify patients with low CD4 counts, who are at highest risk for cryptococcal meningitis. Patients with symptoms need treatment.

These cases are often viral, and enterovirus is the most common pathogen in immunocompetent individuals.2,4 The most common etiology in U.S. adults hospitalized for meningitis is enterovirus (50.9%), followed by unknown etiology (18.7%), bacterial (13.9%), herpes simplex virus (HSV; 8.3%), noninfectious (3.5%), fungal (2.7%), arboviruses (1.1%), and other viruses (0.8%).5 Enterovirus and mosquito-borne viruses, such as St. Louis encephalitis and West Nile virus, often present in the summer and early fall.4,6 HSV and varicella zoster virus can cause meningitis and encephalitis.2, Causative bacteria in community-acquired bacterial meningitis vary depending on age, vaccination status, and recent trauma or instrumentation7,8 (Table 29 ). CNS disease usually presents as meningitis and on rare occasions as single or multiple focal mass lesions (cryptococcomas). Defining the presence of meningitis and its severity is essential; there is no adequate substitute for examination of the CSF. You can review and change the way we collect information below. The desired outcome is resolution of abnormalities, such as fever, headache, altered mental status, meningeal signs, elevated intracranial pressure, and cranial nerve abnormalities. A fungus called C. neoformans causes most cases of CM. Relapse rates were 2% for fluconazole and 17% for amphotericin B. Drug acquisition costs are high for antifungal therapies administered for 612 months. Currently, these tests are unavailable in many parts of the world. These pathogens include enterohemorrhagicEscherichia coliO157:H7,Shigella spp,hepatitis A virus, noroviruses, rotavirus,C. difficile. Patients are usually treated with two antifungal agents and the . Learn more about potential causes and risk. Cryptococcal meningitis usually presents as a subacute meningoencephalitis. Additional costs are accrued for daily, weekly, and monthly monitoring of therapies associated with most of the recommended regimens. The evidence for corticosteroids is heterogeneous and limited to specific bacterial pathogens,3844 but the organism is not usually known at the time of the initial presentation. However, owing to the toxicity of this regimen, it is recommended only as an alternative option for therapy [16] (CII). 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. Introduction: Cryptococcal Meningitis (CM) remains a high-risk clinical condition, and many patients require emergency department (ED) management for complications and stabilization. This trial was terminated by an independent data safety monitoring board after preliminary results revealed a CSF culture relapse rate of 4% among patients receiving fluconazole (200 mg/d), compared with 24% relapse among itraconazole (200 mg/d) recipients [17]. Among patients with HIV infection and cryptococcal meningitis, induction therapy with amphotericin B (0.71 mg/kg/d) plus flucytosine (100 mg/kg/d for 2 weeks) followed by fluconazole (400 mg/d) for a minimum of 10 weeks is the treatment of choice. 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. Similarly, therapy with a combination of fluconazole plus flucytosine seems to be superior to fluconazole alone [16, 28], although this regimen is more toxic than fluconazole monotherapy. Most people likely breathe in this microscopic fungus at some point in their lives but never get sick from it. Treatment decisions should not be based routinely or exclusively on cryptococcal polysaccharide antigen titers in either the serum or CSF [31, 34] (AI). Combination therapy of amphotericin B and flucytosine will sterilize CSF within 2 weeks of treatment in 60%90% of patients [1, 3]. Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. In infants and young children, the presentation is often nonspecific. The patient commonly presents with neurological symptoms such as a headache, altered mental status, and other signs and symptoms include lethargy along with fever, stiff neck (both associated with an aggressive inflammatory response), nausea and vomiting. Cookies used to make website functionality more relevant to you. Antifungal medicine treats meningitis in those who have it, and can prevent meningitis in those who do not. Cookies used to track the effectiveness of CDC public health campaigns through clickthrough data. 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,. Guidelines for diagnosing, preventing and managing cryptococcal disease The test accurately detects cryptococcal infections more than 95% of the time. 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. It isnt found in bird droppings. One-fourth of the patients had opening pressures >350 mm H2O [22]. Similarly, HIV-negative patients may have elevated CSF pressure associated with meningeal inflammation, crypto-coccomas, and either communicating or, very rarely, obstructive hydrocephalus. All information these cookies collect is aggregated and therefore anonymous. Owing to its inherent toxicity and difficulty of administration, this therapy is recommended only in this salvage setting [14] (CII). The panel conferred in person (on 2 occasions), by conference call, and through written reviews of each draft of the manuscript. Cryptococcal meningitis | British Medical Bulletin | Oxford Academic Let's discuss when to get it and possible side effects: Learn how COVID-19 could lead to meningitis in rare cases and what it may mean for your treatment and outlook. You can learn more about how we ensure our content is accurate and current by reading our. 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. Prompt recognition of a potential case of meningitis is essential so that empiric treatment may begin as soon as possible. Guidelines for The Diagnosis, Prevention and Management of Cryptococcal cryptococcal, or other . 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. Fluconazole (400800 mg/d) plus flucytosine (100150 mg/kg/d) for 6 weeks is an alternative to the use of amphotericin B, although toxicity with this regimen is high. Radiographic imaging of the brain is recommended prior to performance of the initial lumbar puncture to rule out the presence of a space-occupying lesion [21] (BII). Its associated with trees, most commonly eucalyptus trees. It may be prudent to use doses of 200 mg of itraconazole twice daily (BIII). For those patients with HIV who present with isolated pulmonary or urinary tract disease, fluconazole at 200400 mg/d is indicated. Meningitis can be caused by fungi, parasites, injury, or viral or bacterial infection. Induction therapy. If you need to go back and make any changes, you can always do so by going to our Privacy Policy page. Dose-limiting adverse effects (predominantly gastrointestinal in nature) that resulted in the discontinuation of flucytosine were reported in 28% of patients; and another 32% described significant side effects that did not result in the discontinuation of therapy. How is cryptococcal meningitis diagnosed? Other laboratory testing and clinical decision rules, such as the Bacterial Meningitis Score, may be useful adjuncts. Your doctor may also test your blood. The etiologies of meningitis range in severity from benign and self-limited to life-threatening with potentially severe morbidity. In cases of extrapulmonary, non-CNS disease, resolution of symptoms and signs, as well as other markers of disease (e.g., radiographic abnormalities), is the desired outcome. Cryptococcal meningitis in an immunocompetent patient It is associated with a variety of complications including disseminated disease as well as neurologic complications . Author disclosure: No relevant financial affiliations. 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. For patients who are unable to tolerate fluconazole, itraconazole (200 mg twice daily) may be substituted (CIII). Meningitis Treatment & Management - Medscape
