Youll typically receive amphotericin B intravenously, meaning directly into your veins. Reprints or correspondence: Dr. Michael S. Saag, University of Alabama at Birmingham, 908 20th Street South, Birmingham, AL 35294-2050 (. In all cases of cryptococcal meningitis, careful attention to the management of intracranial pressure is imperative to assure optimal clinical outcome. INTRODUCTION. Most common causes are viral or autoimmune. 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]. Cryptococcal meningitis pathophysiology includes brain damage. Outcomes. If any test is positive for C. neoformans, then a CSF examination is recommended to exclude cryptococcal 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). A potential treatment option is combination therapy with fluconazole, 400 mg/d, plus flucytosine, 150 mg/kg/d, for 10 weeks; however, the toxicity associated with this regimen limits its utility [15] (CII). Aseptic meningitis is the most common form of meningitis with an annual incidence of 7.6 per 100,000 adults. They help us to know which pages are the most and least popular and see how visitors move around the site. Selection of the appropriate empiric antibiotic regimen is primarily based on age (Table 29 ). Objectives. These agents can be used alone or in combination with other agents with varying degrees of success. However, owing to the toxicity of this regimen, it is recommended only as an alternative option for therapy [16] (CII). But the conditional rarely occurs in someone who has a normal immune system. Your doctor will insert a needle and collect a sample of your spinal fluid. Patients with symptoms need treatment. These essential medications are often unavailable in areas of the world where they are most needed. The prevention of progression to cryptococcal meningitis is the principal goal of therapy in this population. However, this is not possible in many areas of high incidence, and it should not delay diagnosis. 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 . For patients with more severe disease, treatment with amphotericin B (0.51 mg/kg/d) may be necessary for 610 weeks. The differential . Drug acquisition costs are high for antifungal therapies administered for life. Ventriculoperitoneal shunts may become secondarily infected with bacteria; however, this is an uncommon complication. Lipid formulations of amphotericin B can be substituted for amphotericin B for patients whose renal function is impaired. This content is owned by the AAFP. It grows in the debris around the base of the eucalyptus tree. Components of a Protective Environment, Figure. The choice of treatment for disease caused by Cryptococcus neoformans depends on both the anatomic sites of involvement and the host's immune status. Learn how it can, Recurrent meningitis is a rare condition that happens when meningitis goes away and comes back again. Although no specific studies have been designed to investigate treatment options for such patients, they should be treated. This combination helps treat the condition quicker. 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]. Lipid formulations of amphotericin B appear beneficial and may be useful for patients with cryptococcal meningitis and renal insufficiency [12, 1821] (CII). Airborne Precautions if pulmonary infiltrate, Airborne Precautions plus Contact Precautions, if potentially infectious draining body fluid present, Petechial/ecchymotic with fever (general). The usual precautions apply regarding lumbar puncture in this setting, and a CT head scan prior to lumbar puncture would always be preferable in suspected cryptococcal meningitis. Surgery should be performed for patients with persistent or refractory pulmonary or bone disease, but it is rarely needed. Common manifestations in this setting include papilledema, hearing loss, loss of visual acuity, pathological reflexes, severe headache, and abnormal mentation. The treatment for cryptococcal meningitis is intravenous administration of amphotericin B; may be used with or without 5-flucytosine. 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. Placement of a ventriculoperitoneal shunt requires neurosurgical intervention with general anesthesia, which is an expensive, but potentially life-saving, procedure. There is little to distinguish cryptococcal pneumonia from other causes of atypical pneumonia in HIV-infected patients. C. gattii is more likely to infect someone with a healthy immune system than C. neoformans. At the present time, in addition to amphotericin B and flucytosine, other drugs, namely fluconazole, itraconazole, and lipid formulations of amphotericin B, are available to treat cryptococcal infections. To further complicate the diagnostic process, physical examination and testing are limited in sensitivity and specificity. All Rights Reserved. Meningitis can be caused by fungi, parasites, injury, or viral or bacterial infection. In cases where fluconazole cannot be given, itraconazole is an acceptable, albeit less effective, alternative [9, 33] (B, I). on chest radiograph. 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]. In cases of CNS masses (cryptococcoma), resolution of lesions is the desired outcome. Dexamethasone should be administered to children and adults with suspected bacterial meningitis before or at the time of initiation of antibiotics. Toxicity associated with use of fluconazole/flucytosine combination therapy is substantial [15]. Drug-related toxicities and development of adverse drug-drug interactions are the principal potential harms of therapeutic intervention. The differential diagnosis is broad (Table 1). Therefore, initial therapy with fluconazole, even among low risk patients, is discouraged (DIII). These cookies may also be used for advertising purposes by these third parties. This test cannot be used to rule out bacterial meningitis.7. Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. 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, or masses) on chest radiograph. In cases where repeated lumbar punctures or use of a lumbar drain fail to control elevated pressure symptoms, or when persistent or progressive neurological deficits are present, a ventriculoperitoneal shunt is indicated [21, 22] (BII). Because clinical findings are also unreliable, the diagnosis relies on the examination of cerebrospinal fluid obtained from lumbar puncture. Last medically reviewed on December 11, 2017, Meningitis is an inflammation of the fluid and membranes surrounding the brain and spinal cord. 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. C. neoformans infection statistics. Two types of fungus can cause cryptococcal meningitis (CM). Adverse effects from fluconazole monotherapy at 400 mg daily are uncommon. Therefore, the specific treatment of choice has not been fully elucidated. In cases where fluconazole is not an option, an acceptable alternative is itraconazole, 400 mg/d for life [9] (CII). Bacterial meningitis classically has a very high and predominantly neutrophilic pleocytosis, low glucose level, and high protein level. Respiratory syncytial virus, parainfluenza virus, adenovirus, influenza virus, Contact plus Droplet Precautions; Droplet Precautions may be discontinued when adenovirus and influenza have been ruled out, Abscess or draining wound that cannot be covered, If positive history of travel to an area with an ongoing outbreak of VHF in the 10 days before onset of fever. Costs. For full access to this pdf, sign in to an existing account, or purchase an annual subscription. Treatment of tuberculous, cryptococcal, or other fungal meningitides is beyond the scope of this article, but should be considered if risk factors are present (e.g., travel to endemic areas, immunocompromised state, human immunodeficiency virus infection). Management of elevated intracranial pressure in HIV-infected patients with cryptococcal disease. Prospective clinical trials and carefully conducted observational studies show that potent antiretroviral therapy reduces the incidence of opportunistic infections [2527]. Its usually found in soil that contains bird droppings. 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). Fluconazole is well-tolerated; nausea, abdominal pain, and skin rash are the most common adverse effects. If you need to go back and make any changes, you can always do so by going to our Privacy Policy page. Classic signs of meningeal irritation commonly are absent on physical examination, and routine laboratory assessment is rarely revealing. The test accurately detects cryptococcal infections more than 95% of the time. cryptococcal, or other . Additional costs are accrued for monthly monitoring and supervision of therapies associated with most of the recommended regimens. Meningitis can be caused by different germs, including bacteria,. Delayed initiation of antibiotics can worsen mortality. Cryptococcosis is a pulmonary or disseminated infection acquired by inhalation of soil contaminated with the encapsulated yeasts Cryptococcus neoformans or C. gattii. Systemic complications of acute bacterial meningitis must be treated, including the following: Hypotension or shock Hypoxemia Hyponatremia (from syndrome of inappropriate antidiuretic hormone. Meningitis is an inflammatory process involving the meninges. 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. Recommendations. Youll need to get spinal fluid testing repeatedly during treatment. 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]. As a result, most clinicians are uncertain about which agents to use for which underlying disease state, in what combination, and for what duration. It is clear that all immunocompromised patients require treatment, since they are at high risk for development of disseminated infection. Meningitis can be caused by different germs, including bacteria, fungi, and viruses. Among those individuals who are unable to tolerate fluconazole, itraconazole (200400 mg/d) is an acceptable alternative. It is necessary to carefully monitor serum electrolytes, renal function, and bone marrow function. Your Guide to Salmonella Meningitis and How to Spot It, Group B Streptococcal (GBS) Meningitis: Symptoms, Treatment, Outlook, and More. Also, it is optional to continue fluconazole (200 mg/d) for 612 months (BIII). According to the British Medical Bulletin, 10 to 30 percent of people with HIV-related CM die from the illness. Patients with the syndromes or conditions listed below may present with atypical signs or symptoms (e.g.neonates and adults with pertussis may not have paroxysmal or severe cough). It is associated with a variety of complications including disseminated disease as well as neurologic complications . 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]. 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. 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. Oxford University Press is a department of the University of Oxford. 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. Specific pathogens are more prevalent in certain age groups, but empiric coverage should cover most possible culprits. Recommendations. Working with health programs to introduce and implement cryptococcal screening and treatment, Helping health programs assess costs and impact of cryptococcal screening activities, Supporting training of clinical and laboratory staff on diagnosing, treating, and managing cryptococcal infection and cryptococcal meningitis, Collaborating with partners to improve access to cryptococcal diagnostics and antifungal drugs. Few studies have been conducted that specifically evaluate outcomes among HIV-negative patients with pulmonary or non-CNS disease. You will be subject to the destination website's privacy policy when you follow the link. Acute bacterial meningitis must be treated right away with intravenous antibiotics and sometimes corticosteroids. 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). Options. Patients may also present with neurological deficits, altered mental status, and seizures, indicating increased intracranial pressure (ICP). The toxicity of amphotericin B limits its utility as a desired agent in the treatment of mild-to-moderate pulmonary disease among immunocompetent hosts. Itraconazole appears less active than fluconazole [17, 33]. People with advanced HIV should be tested early for cryptococcal infection. In cases where flucytosine cannot be administered, amphotericin B alone (administered at the same doses listed above) is an acceptable alternative [13] (BI). In cases of CNS mass lesions (cryptococcomas), radiographic resolution of lesions is the desired outcome. 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). However, no randomized studies in these population groups have been completed in the era of triazole therapy. Most patients with cryptococcal meningoencephalitis are immunocompromised. Fifteen percent of patients in the placebo arm developed CNS relapse compared with no relapses in the fluconazole group. 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. Among patients with solid organ transplants, aggressive treatment of early cryptococcal disease may prevent loss of the transplanted organ. Specific recommendations for the treatment of HIV-associated cryptococcal pulmonary disease are summarized in table 2. To screen people living with HIV for early cryptococcal infection and cryptococcal meningitis, healthcare facilities and laboratories must have access to the reliable tests. 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. 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]. A summary of treatment recommendations for AIDS-associated cryptococcal meningitis is provided in table 2. Your doctor will also perform a physical examination when trying to figure out if you have CM. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Bacterial meningitis is a medical emergency that requires prompt recognition and treatment. 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]. If SARS and tuberculosis unlikely, use Droplet Precautions instead of Airborne Precautions. Causes In most cases, cryptococcal meningitis is caused by the fungus Cryptococcus neoformans. These cookies may also be used for advertising purposes by these third parties. Cryptococcal meningitis is a fungal infection that usually affects people with a weakened immune system. The content is unchanged. Measuring stigma associated with hepatitis B virus infection in Sierra Leone: Validation of an abridged Berger HIV stigma scale. Treatment should be started promptly in cases where transfer, imaging, or lumbar puncture may slow a definitive diagnosis. 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. Classic symptoms of pneumonitis, including cough, fever, and sputum production, may be present, or pleural symptoms may predominate. Specific recommendations for the treatment of non-HIV-associated cryptococcal pulmonary disease are summarized in table 1. Elevated intracranial pressure is an important contributor to morbidity and mortality of cryptococcal meningitis. *Infection control professionals should modify or adapt this table according to local conditions. We provide a complete overview, including causes, symptoms, and treatment. It may be prudent to use doses of 200 mg of itraconazole twice daily (BIII). Benefits and harms. Ketoconazole has in vitro activity against C. neoformans, but is generally ineffective in the treatment of cryptococcal meningitis and should be used rarely, if at all, in this setting [10] (CIII). Control Management of Cases: Enteric precautions are indicated for seven days after onset, unless a non-enteroviral diagnosis is established. These cookies allow us to count visits and traffic sources so we can measure and improve the performance of our site. Most people likely breathe in this microscopic fungus at some point in their lives but never get sick from it. All information these cookies collect is aggregated and therefore anonymous. The optimal dose of lipid formulations of amphotericin B has not been determined, but AmBisome has been effective at doses of 4 mg/kg/d [12]. Such testing is generally best used in cases of relapse or in cases of refractory disease. 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). Cryptococcal meningitis. An alternative to this regimen is amphotericin B (0.71 mg/kg/d) plus 5-flucytosine (100 mg/kg/d) for 2 weeks, followed by fluconazole (400 mg/day) for a minimum of 10 weeks. In addition, anemia occurs frequently and thrombocytemia occurs occasionally (possibly as a result of exposure to heparin). Because of the poor performance of clinical signs to rule out meningitis, all patients who present with symptoms concerning for meningitis should undergo prompt lumbar puncture (LP) and evaluation of cerebrospinal fluid (CSF) for definitive diagnosis. Infections and other disorders affecting the brain and spinal cord can activate the immune system, which leads to inflammation. 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. 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. Patients in the amphotericin B group had significantly more relapses, more drug-related adverse events, and more bacterial infections, including bacteremia [24]. 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. Immunosuppressed patients, such as solid organ transplant recipients, require more prolonged therapy [3]. 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. Options. Most common causes are bacterial or viral. Two clinical trials found that therapy with a combination of amphotericin B plus flucytosine was superior to amphotericin B alone or fluconazole monotherapy [11, 18]. Recommendations. Lumbar drains are typically used in intensive care unit settings, which are associated with higher costs.

Ketoconazole is generally ineffective in the treatment of cryptococcosis in HIV-infected patients and should probably be avoided [10, 30] (DII). In both HIV-negative and HIV-positive patients with cryptococcal meningitis, elevated intracranial pressure occurs in excess of 50% of patients [22]. The presentation of pulmonary cryptococcosis can range from asymptomatic nodular disease to severe acute respiratory distress syndrome (ARDS). The clinicians index of suspicion should be guided by the prevalence of specific conditions in the community, as well as clinical judgment. If you do not allow these cookies we will not know when you have visited our site, and will not be able to monitor its performance. Most parenchymal lesions will respond to antifungal treatment; large (>3 cm) accessible CNS lesions may require surgery. If you need to go back and make any changes, you can always do so by going to our Privacy Policy page. This disease is rare in healthy people. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. The desired outcome is resolution of abnormalities, such as fever, headache, altered mental status, ocular signs, and elevated intracranial pressure. Salmonella meningitis is a kind of bacterial meningitis that can be dangerous if not treated. This fungus is found in soil all over the world. Its associated with trees, most commonly eucalyptus trees. 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. Aggressive management of elevated intracranial pressure is perhaps the most important factor in reducing mortality and minimizing morbidity of acute cryptococcal meningitis. The most common choice is amphotericin B. Youll need to take the drug daily. This material may not otherwise be downloaded, copied, printed, stored, transmitted or reproduced in any medium, whether now known or later invented, except as authorized in writing by the AAFP. 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). Additional costs are accrued for monthly monitoring of therapies associated with most of the recommended regimens. Some HIV-infected patients present with isolated cryptococcemia or a positive serum cryptococcal antigen titer (>1 : 8) without evidence of clinical disease. Yet, because of the potentially grave consequences of overlooking this illness, it is imperative to assess AIDS patients with pneumonia for possible fungal infection. However, it is also important to exclude cryptococcal meningitis in patients with seizures, bizarre behavior, confusion, progressive dementia, or unexplained fever. Cryptococcal antigen, a biological marker that indicates a person has cryptococcal infection, can be detected in the body weeks before symptoms of meningitis appear. Early, appropriate treatment of cryptococcal meningitis reduces both morbidity and mortality. The panel conferred in person (on 2 occasions), by conference call, and through written reviews of each draft of the manuscript. It is clear that all HIV-infected patients require treatment, since they are at high risk for disseminated infection. See permissionsforcopyrightquestions and/or permission requests. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. Cryptococcal meningitis is a fungal infection of the tissues covering the brain and spinal cord. 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 ). Flucytosine dosage must be adjusted on the basis of hematologic toxicities or, preferably, based on measurement of flucytosine levels. The objective of treatment is eradication of the infection and control of elevated intracranial pressure. Occasionally patients who present with extremely high opening pressures (>400 mm H2O) may require a lumbar drain, especially when frequent lumbar punctures are required to or fail to control symptoms of elevated intracranial pressure.
