One large cohort study found a 4.5% mortality rate and a 30.9% rate of complications, such as developmental delay, seizure disorder, or hearing loss, for childhood encephalitis and meningitis combined.50 Tuberculous meningitis also has a higher mortality rate (19.3%) with a higher risk of neurologic disease in survivors (53.9%).51 A recent prospective cohort study also found that males had a higher risk of unfavorable outcomes (odds ratio = 1.34) and death (odds ratio = 1.47).52, Complications from bacterial meningitis also vary by age (Table 71,11,12,46,5356 ). Cryptococcal meningitis : a deadly fungal disease among people living 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. Patients with symptoms need treatment. Your Guide to Salmonella Meningitis and How to Spot It, Group B Streptococcal (GBS) Meningitis: Symptoms, Treatment, Outlook, and More. Cryptococcal antigen can be found in the body weeks before symptoms of meningitis. Costs. 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. 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. The panel conferred in person (on 2 occasions), by conference call, and through written reviews of each draft of the manuscript.

Meningitis - National Institute of Neurological Disorders and Stroke 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). Currently, these tests are unavailable in many parts of the world. The principal intervention for reducing elevated intracranial pressure is percutaneous lumbar drainage [21, 22] (AII). Patients are usually treated with two antifungal agents and the . Pneumonia is thought to herald the onset of disseminated disease. Airborne plus Contact Precautions plus eye protection. To further complicate the diagnostic process, physical examination and testing are limited in sensitivity and specificity. The test accurately detects cryptococcal infections more than 95% of the time. Durable Viral Suppression Among Young Adults Living with HIV Receiving Ryan White Services in New York City. 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. Lumbar drains are typically used in intensive care unit settings, which are associated with higher costs. PDF Communicable Disease Management Protocol Viral Meningitis/Encephalitis Most people who develop CM already have severely compromised immune systems. Systemic complications of acute bacterial meningitis must be treated, including the following: Hypotension or shock Hypoxemia Hyponatremia (from syndrome of inappropriate antidiuretic hormone. Abstract. For patients with more severe disease, treatment with amphotericin B (0.51 mg/kg/d) may be necessary for 610 weeks. 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. Fluconazole is well-tolerated; nausea, abdominal pain, and skin rash are the most common adverse effects. 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]. Oral fluconazole, 200 mg/d, is the most effective maintenance therapy for AIDS-associated cryptococcal meningitis [17, 24] (AI). 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. Patients who test positive for cryptococcal antigen can take antifungal medicine. 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. 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). 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. U.S. Centers for Disease Control and Prevention (CDC), bmb.oxfordjournals.org/content/72/1/99.full, cdc.gov/fungal/diseases/cryptococcosis-neoformans/statistics.html, hivinsite.ucsf.edu/InSite?page=md-agl-crypcoc, mayoclinic.org/diseases-conditions/meningitis/basics/definition/con-20019713, Bacterial, Viral, and Fungal Meningitis: Learn the Difference, Recurrent Meningitis: A Rare but Serious Condition, Understanding the Meningitis Vaccine: What It Is and When You Need It. Intrathecal or intraventricular amphotericin B may be used in refractory cases where systemic administration of antifungal therapy has failed. The objective of treatment is eradication of the infection and control of elevated intracranial pressure. 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. Viral meningitis (non-HSV) management is focused on supportive care. In cases where fluconazole is not an option, an acceptable alternative is itraconazole, 400 mg/d for life [9] (CII). See additional information. 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). Combination therapy of amphotericin B and flucytosine will sterilize CSF within 2 weeks of treatment in 60%-90% of patients [ 1, 3 ]. However, cryptococcal meningitis is still a major problem where HIV prevalence is high and where access to healthcare may be limited. A randomized comparative trial demonstrated the superiority of fluconazole (200 mg/d) over amphotericin B (1 mg/kg/w) as maintenance therapy [24]. Drug acquisition costs are high for antifungal therapies administered for life. Because of the risk of increased intracranial pressure with brain inflammation, the Infectious Diseases Society of America recommends performing computed tomography of the head before LP in specific high-risk patients to reduce the possibility of cerebral herniation during the procedure (Table 4).7,21,22 However, recent retrospective data have shown that removing the restriction on LP in patients with altered mental status reduced mortality from 11.7% to 6.9%, suggesting it may be safe to proceed with LP in these patients.22, The CSF findings typical of aseptic meningitis are a relatively low and predominantly lymphocytic pleocytosis, normal glucose level, and a normal to slightly elevated protein level (Table 59 ). Objectives. Maintain isolation precautions as necessary with bacterial meningitis. You will be subject to the destination website's privacy policy when you follow the link. These patients, as well as those coinfected with human immunodeficiency virus, should be managed in consultation with an infectious disease subspecialist when available. Toxicity associated with use of fluconazole/flucytosine combination therapy is substantial [15]. Most of the illness and deaths are estimated to occur in resource-limited countries, among people living with HIV. In both HIV-negative and HIV-positive patients with cryptococcal meningitis, elevated intracranial pressure occurs in excess of 50% of patients [22]. GBS meningitis typically affects newborns but can affect adults too. 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). INTRODUCTION. Despite the absence of controlled clinical trial data from HIV-negative populations of patients, a frequently used alternative treatment for cryptococcal meningitis in immunocompetent patients is an induction course of amphotericin B (0.51 mg/kg/d) with flucytosine (100 mg/kg/d) for 2 weeks, followed by consolidation therapy with fluconazole (400 mg/d) for an additional 810 weeks [7] (BIII). HILLARY R. MOUNT, MD, AND SEAN D. BOYLE, DO. These materials are intended to support cryptococcal screen-and-treat programs. 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). Early, appropriate treatment of cryptococcal meningitis reduces both morbidity and mortality. Meningitis is an infection and inflammation of the meninges, which are the membranes that cover the brain and spinal cord. Preferred treatment options for cryptococcal disease in HIV-negative patients. The authors thank Thomas Lamarre, MD, for his input and expertise. Patients should initially undergo daily lumbar punctures to maintain CSF opening pressure in the normal range. Oxford University Press is a department of the University of Oxford. This combination helps treat the condition quicker. 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). Airborne Precautions if pulmonary infiltrate, Airborne Precautions plus Contact Precautions, if potentially infectious draining body fluid present, Petechial/ecchymotic with fever (general). Your doctor will monitor you closely while youre on this drug to watch for nephrotoxicity (meaning the drug can be toxic to your kidneys). 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]. This content is owned by the AAFP. 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]. CDC twenty four seven. 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). 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. They are called Cryptococcus neoformans (C. neoformans) and Cryptococcus gattii (C. gattii). Objective: This narrative review provides an evidence-based summary of the current data for the emergency medicine evaluation and management of CM. We characterized 110 Cryptococcus strains collected from Xiangya Hospital of Central South University in China during the 6-year study period between 2013 and 2018, and performed their antifungal susceptibility testing . Worldwide, approximately 1 million new cases of cryptococcal meningitis occur each year, resulting in 625,000 deaths. While awaiting the results of imaging studies, the serum should be tested for the presence of cryptococcal polysaccharide antigen. 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.) Two types of fungus can cause cryptococcal meningitis (CM). 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.. Aggressive management of elevated intracranial pressure is perhaps the most important factor in reducing mortality and minimizing morbidity of acute cryptococcal meningitis. This fungus is found in soil all over the world. 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]. Cryptococcal meningitis: Symptoms, causes, and treatment When the CSF pressure is normal for several days, the procedure can be suspended. Worldwide, nearly 152,000 new cases of cryptococcal meningitis occur each year, resulting in an estimated 112,000 deaths. 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]. Your doctor will also perform a physical examination when trying to figure out if you have CM. Benefits and harms. 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). Amphotericin B, flucytosine, and fluconazole are antifungal medications shown to improve survival in patients with cryptococcal infections. Drug-related toxicities and development of adverse drug-drug interactions are the principal harms of therapeutic intervention. . Copyright 2017 by the American Academy of Family Physicians. No laboratory or clinical test, such as serial serum or CSF cryptococcal antigen testing, is useful for monitoring for microbial relapse during the maintenance phase of treatment [31, 34]. 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. More Information. Recommendations. Bacterial meningitis is a medical emergency that requires prompt recognition and treatment. 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.
