cryptococcal meningitis isolation precautions

Thus, itraconazole should be used in cases where the patient is intolerant of fluconazole or has failed fluconazole therapy (BI). The goal of treatment is cure of the infection and prevention of dissemination of disease to the CNS. Ventriculoperitoneal shunts may become secondarily infected with bacteria; however, this is an uncommon complication. However, the initial dose should be given earlier in the setting of a high-risk condition, such as functional asplenia or complement deficiencies, travel to endemic areas, or a community outbreak.60 There are also two available vaccines for meningococcal type B strains (MenB-4C [Bexsero] and MenB-FHbp [Trumenba]) to be used in patients with complement disease or functional asplenia, or in healthy individuals at risk during a serogroup B outbreak as determined by the Centers for Disease Control and Prevention.60. Fluconazole consolidation therapy may be continued for as along as 612 months, depending on the clinical status of the patient. The toxicity of amphotericin B limits its utility as a desired agent in the treatment of mild-to-moderate pulmonary disease among immunocompetent hosts.

Abstract. This fungus is found in soil around the world. Thank you for submitting a comment on this article. 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. 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. 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. This disease is rare in healthy people. (2017). Toxic side effects from amphotericin B are common. 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] Treatment decisions should not be based routinely or exclusively on cryptococcal polysaccharide antigen titers in either the serum or CSF [31, 34] (AI). Outcomes. Youll probably also take flucytosine, another antifungal medication, while youre taking the amphotericin B. Youll need to get spinal fluid testing repeatedly during treatment. It is clear that all HIV-infected patients require treatment, since they are at high risk for disseminated infection. Your doctor will insert a needle and collect a sample of your spinal fluid. These cookies allow us to count visits and traffic sources so we can measure and improve the performance of our site. Outcomes. The initial management strategy is outlined in Figure 1.7,9 Stabilization of the patient's cardiopulmonary status takes priority. 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]. Cryptococcal meningitis, mainly caused by Cryptococcus neoformans/gattii species complexes, is a lethal infection in both immunosuppressive and immunocompetent populations. 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. As the overall incidence of cryptococcal disease has increased so has the number of treatment options available to treat the disease. However, no randomized studies in these population groups have been completed in the era of triazole therapy. How is cryptococcal meningitis diagnosed? C. gattii is more likely to infect someone with a healthy immune system than C. neoformans. 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]. Objectives. Outcomes. Neurologic sequelae such as hearing loss occur in approximately 6% to 31% of children and can resolve within 48 hours, but may be permanent in 2% to 7% of children.5356 An audiology assessment should be considered in children before discharge.8 Follow-up should assess for hearing loss (including referral for cochlear implants, if present), psychosocial problems, neurologic disease, or developmental delay.57 Testing for complement deficiency should be considered if there is more than one episode of meningitis, one episode plus another serious infection, meningococcal disease other than serogroup B, or meningitis with a strong family history of the disease.57, Vaccines that have decreased the incidence of meningitis include H. influenzae type B, S. pneumoniae, and N. meningitidis.5860 Administration of one of the meningococcal vaccines that covers serogroups A, C, W, and Y (MPSV4 [Menomune], Hib-MenCY [Menhibrix], MenACWY-D [Menactra], or MenACWY-CRM [Menveo]) is recommended for patients 11 to 12 years of age, with a booster at 16 years of age. Linking to a non-federal website does not constitute an endorsement by CDC or any of its employees of the sponsors or the information and products presented on the website. Selection of the appropriate empiric antibiotic regimen is primarily based on age (Table 29 ). 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. In infants and young children, the presentation is often nonspecific. Three potential options exist for antifungal maintenance therapy: fluconazole, itraconazole, and weekly or biweekly amphotericin B. Outcomes. Our website services, content, and products are for informational purposes only. 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. 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]. The principal intervention for reducing elevated intracranial pressure is percutaneous lumbar drainage [21, 22] (AII). Cryptococcal antigen, a biological marker that indicates a person has cryptococcal infection, can be detected in the body weeks before symptoms of meningitis appear. Cookies used to track the effectiveness of CDC public health campaigns through clickthrough data. These agents can be used alone or in combination with other agents with varying degrees of success. People with advanced HIV should be tested early for cryptococcal infection. 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. The choice of treatment for disease caused by Cryptococcus neoformans depends on both the anatomic sites of involvement and the host's immune status. CDC twenty four seven. Youll receive antifungal drugs if you have CM. 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. All rights reserved. For those individuals who are unable to tolerate fluconazole, itraconazole (200400 mg/day for 612 months) is an acceptable alternative. Bacterial meningitis is a medical emergency that requires prompt recognition and treatment. CDC twenty four seven. If SARS and tuberculosis unlikely, use Droplet Precautions instead of Airborne Precautions. If you need to go back and make any changes, you can always do so by going to our Privacy Policy page. Considerations for Bioterrorist Threats, Table 4. You can review and change the way we collect information below. They help us to know which pages are the most and least popular and see how visitors move around the site. The etiologies of meningitis range in severity from benign and self-limited to life-threatening with potentially severe morbidity. Your doctor may also test your blood. Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. Add Droplet Precautions for the first 24 hours of appropriate antimicrobial therapy if invasive Group A streptococcal disease is suspected, Centers for Disease Control and Prevention. INTRODUCTION. 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). Recommendations. In cases of CNS mass lesions (cryptococcomas), radiographic resolution of lesions is the desired outcome. Oxford University Press is a department of the University of Oxford. Indeed, few studies have been conducted that specifically evaluate outcomes among HIV-infected patients with pulmonary or non-CNS disease. Whether the CNS disease is associated with involvement of other body sites, treatment remains the same. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. 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. Treatment should not be delayed if there is lag time in the evaluation. 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). Patients are usually treated with two antifungal agents and the . Cryptococcal antigen can be found in the body weeks before symptoms of meningitis. 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. Cookies used to track the effectiveness of CDC public health campaigns through clickthrough data. These materials are intended to support cryptococcal screen-and-treat programs. Owing to its inherent toxicity and difficulty of administration, it is recommended only in a salvage setting [14] (CII). Prolonged external lumbar drainage places patients at major risk for bacterial infection. 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. In cases where flucytosine cannot be administered, amphotericin B alone (administered at the same doses listed above) is an acceptable alternative [13] (BI). 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. Meningitis can be caused by fungi, parasites, injury, or viral or bacterial infection. Most parenchymal lesions will respond to antifungal treatment; large (>3 cm) accessible CNS lesions may require surgery. 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). 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. 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]. Because of the relatively rapid emergence of drug resistance, flucytosine is not employed as a single agent and is, therefore, only used in combination with amphotericin B or fluconazole. CM usually occurs in people who have a compromised immune system. Copyright 2017 by the American Academy of Family Physicians. Drug acquisition costs are high for antifungal therapies administered for life. 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. on chest radiograph. Other laboratory testing and clinical decision rules, such as the Bacterial Meningitis Score, may be useful adjuncts. CNS disease usually presents as meningitis and on rare occasions as single or multiple focal mass lesions (cryptococcomas). Patients with meningitis present a particular challenge for physicians. These tissues are called meninges. Examination maneuvers such as Kernig sign or Brudzinski sign may not be useful to differentiate bacterial from aseptic meningitis because of variable sensitivity and specificity. In cases of CNS masses (cryptococcoma), resolution of lesions is the desired outcome. However, in patients with HIV or AIDS, the yearly incidence rate is between 2 and 7 cases per 1,000 people. Microscopy of cerebrospinal fluid Vaccination against the most common pathogens that cause bacterial meningitis is recommended. The organism has a strong predilection for infecting the CNS; however, infection has been reported in virtually every organ in the body. Specific recommendations for the treatment of non-HIV-associated cryptococcal meningitis are summarized in table 1. 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. Therefore, the specific treatment of choice has not been fully elucidated. A lumbar puncture is recommended after 2 weeks of treatment to assess the status of CSF sterilization. Therefore, initial therapy with fluconazole, even among low risk patients, is discouraged (DIII). Patient information: See related handout on meningitis, written by the authors of this article. Patients with a positive culture at 2 weeks may require a longer course of induction therapy. Author disclosure: No relevant financial affiliations. The desired outcome is continued absence of symptoms associated with cryptococcal meningitis and resolution or stabilization of cranial nerve abnormalities. 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. Introduction: Cryptococcal Meningitis (CM) remains a high-risk clinical condition, and many patients require emergency department (ED) management for complications and stabilization. In a large analysis of patients from 1998 to 2007, the overall mortality rate in those with bacterial meningitis was 14.8%.1 Worse outcomes occurred in those with low Glasgow Coma Scale scores, systemic compromise (e.g., low CSF white blood cell count, tachycardia, positive blood cultures, abnormal neurologic examination, fever), alcoholism, and pneumococcal infection.1113,16 Mortality is generally higher in pneumococcal meningitis (30%) than other types, especially penicillin-resistant strains.12,48,49 Viral meningitis outside the neonatal period has lower mortality and complication rates, but large studies or reviews are lacking. Aseptic meningitis is the most common form of meningitis with an annual incidence of 7.6 per 100,000 adults. Delayed initiation of antibiotics can worsen mortality. A fungus called C. neoformans causes most cases of CM. Among patients with normal baseline opening pressure (<200 mm H2O), a repeat lumbar puncture should be performed 2 weeks after initiation of therapy to exclude elevated pressure and to evaluate culture status. C. gattii also causes CM. There are no controlled clinical trials describing the outcome of therapy for AIDS-related cryptococcal pneumonia (table 2). Options. Among patients with AIDS- associated cryptococcal meningitis who are treated successfully, there is a high risk of relapse in the absence of maintenance therapy. Similarly, HIV-negative patients may have elevated CSF pressure associated with meningeal inflammation, crypto-coccomas, and either communicating or, very rarely, obstructive hydrocephalus. 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). 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. 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. In each case, careful assessment of the CNS is required to rule out occult meningitis. Learn about the risk factors and complications. Search dates: October 1, 2016, and March 13, 2017. Fluconazole should be continued for life. This is especially true in people who have AIDS. Systemic complications of acute bacterial meningitis must be treated, including the following: Hypotension or shock Hypoxemia Hyponatremia (from syndrome of inappropriate antidiuretic hormone. The presence of a positive serum cryptococcal antigen titer implies deep tissue invasion and a high likelihood of disseminated disease. Youll probably switch to taking only fluconazole for about eight weeks. These pathogens include enterohemorrhagicEscherichia coliO157:H7,Shigella spp,hepatitis A virus, noroviruses, rotavirus,C. difficile. All patients should be monitored closely for evidence of elevated intracranial pressure and managed in a fashion similar to HIV-positive patients (see below). Options. 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). Learn how it can, Recurrent meningitis is a rare condition that happens when meningitis goes away and comes back again. Three percent of fluconazole patients and 37% of placebo patients relapsed at any site. Meningitis is an infection of the meninges, the membranes that surround the brain and spinal cord. These cookies allow us to count visits and traffic sources so we can measure and improve the performance of our site. Aseptic meningitis is the most common form. Additional costs are accrued for daily, weekly, and monthly monitoring of therapies associated with most of the recommended regimens. This specific species is an emerging pathogen and is best known for the 2013 outbreak in the U.S. Pacific Northwest. 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. For immunocompetent hosts with isolated pulmonary disease, careful observation may be warranted; in the case of symptomatic infection, indicated treatment is fluconazole, 200400 mg/day for 36 months. Patients who test positive for cryptococcal antigen can take antifungal medicine. Early, appropriate treatment of HIV-associated cryptococcal meningitis significantly reduces both the morbidity and mortality associated with this disorder. Most common causes are viral or autoimmune. Currently, these tests are unavailable in many parts of the world. Maintain isolation precautions as necessary with bacterial meningitis. Aggressive management of elevated intracranial pressure is perhaps the most important factor in reducing mortality and minimizing morbidity of acute cryptococcal meningitis. Ketoconazole is not effective as maintenance therapy [30] (DII). Before 1950, disseminated cryptococcal disease was uniformly fatal. Patients should initially undergo daily lumbar punctures to maintain CSF opening pressure in the normal range. 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. 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. According to the British Medical Bulletin, 10 to 30 percent of people with HIV-related CM die from the illness. Additional costs are accrued for monthly monitoring and supervision of therapies associated with most of the recommended regimens. You can learn more about how we ensure our content is accurate and current by reading our. Your comment will be reviewed and published at the journal's discretion. To screen people living with HIV for early cryptococcal infection and cryptococcal meningitis, healthcare facilities and laboratories must have access to the reliable tests. Lumbar drains are typically used in intensive care unit settings, which are associated with higher costs. If your tests come back negative for CM for two weeks, your doctor will probably ask you to stop taking amphotericin B and flucytosine. For those patients with HIV who present with isolated pulmonary or urinary tract disease, fluconazole at 200400 mg/d is indicated. Patients who tests positive for cryptococcal antigen can take antifungal medication to help the body fight the early stage of the infection. C. neoformans infection statistics.
