Systemic complications of acute bacterial meningitis must be treated, including the following: Hypotension or shock Hypoxemia Hyponatremia (from syndrome of inappropriate antidiuretic hormone. Placement of a ventriculoperitoneal shunt requires neurosurgical intervention with general anesthesia, which is an expensive, but potentially life-saving, procedure. In cases where fluconazole is not an option, an acceptable alternative regimen is itraconazole, 200400 mg/d, for 612 months [9] (BIII). Bacterial meningitis classically has a very high and predominantly neutrophilic pleocytosis, low glucose level, and high protein level. Cryptococcal meningitis is a serious disorder with high mortality and thus best managed by an interprofessional team that includes a radiologist, emergency department physician, internist, infectious disease specialist, infectious disease nurse, neurologist and a pharmacist. Few studies have been conducted that specifically evaluate outcomes among HIV-negative patients with pulmonary or non-CNS disease. Maintenance therapy. How is cryptococcal meningitis diagnosed? Oral fluconazole, 200 mg/d, is the most effective maintenance therapy for AIDS-associated cryptococcal meningitis [17, 24] (AI). These pathogens include enterohemorrhagicEscherichia coliO157:H7,Shigella spp,hepatitis A virus, noroviruses, rotavirus,C. difficile.

The organisms listed under the column Potential Pathogens are not intended to represent the complete, or even most likely, diagnoses, but rather possible etiologic agents that require additional precautions beyond Standard Precautions until they can be ruled out. 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. 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. It may be prudent to use doses of 200 mg of itraconazole twice daily (BIII). 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. The goal of treatment is control of the infection and prevention of dissemination of disease to the CNS. The most troublesome toxic side effect is renal injury, including elevation of the serum creatinine, hypokalemia, hypomagnesemia, and renal tubular acidosis.

The antibiotic or combination of antibiotics depends on the type of bacteria causing the infection. A lumbar puncture is recommended after 2 weeks of treatment to assess the status of CSF sterilization. Abstract. Some patients present with isolated cryptococcemia, a positive serum cryptococcal antigen titer (>1 : 8) without evidence of clinical disease, or a positive urine culture or prostatic disease. Lumbar puncture may be performed without computed tomography of the brain if there are no risk factors for an occult intracranial abnormality. Options. The objective of treatment is eradication of the infection and control of elevated intracranial pressure. The choice of treatment for disease caused by Cryptococcus neoformans depends on both the anatomic sites of involvement and the host's immune status. Therefore, the specific treatment of choice and the optimal duration of treatment have not been fully elucidated for HIV-negative patients.

Options. These materials are intended to support cryptococcal screen-and-treat programs. However, owing to the toxicity of this regimen, it is recommended only as an alternative option for therapy [16] (CII). CDC twenty four seven. 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. If you need to go back and make any changes, you can always do so by going to our Privacy Policy page. The symptoms of CM usually come on slowly. Aggressive management of elevated intracranial pressure has not been employed consistently in HIV-negative patients with cryptococcal meningitis, and its impact on outcome is unclear. Patients with meningitis present a particular challenge for physicians. Treatment should be started promptly in cases where transfer, imaging, or lumbar puncture may slow a definitive diagnosis. Toxicity associated with use of fluconazole/flucytosine combination therapy is substantial [15]. 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 ). Elevated intracranial pressure is an important contributor to morbidity and mortality of cryptococcal meningitis. The prevention of progression to cryptococcal meningitis is the principal goal of therapy in this population. See permissionsforcopyrightquestions and/or permission requests. This combination helps treat the condition quicker. 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. 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. Dexamethasone should be administered to children and adults with suspected bacterial meningitis before or at the time of initiation of antibiotics. 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]. 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. Objectives. Treatment should not be delayed if there is lag time in the evaluation. Common manifestations in this setting include papilledema, hearing loss, loss of visual acuity, pathological reflexes, severe headache, and abnormal mentation. Objective: This narrative review provides an evidence-based summary of the current data for the emergency medicine evaluation and management of CM. Maintain isolation precautions as necessary with bacterial meningitis. Worldwide, approximately 1 million new cases of cryptococcal meningitis occur each year, resulting in 625,000 deaths.

All information these cookies collect is aggregated and therefore anonymous. Early, appropriate treatment of cryptococcal meningitis reduces both morbidity and mortality. A randomized comparative trial demonstrated the superiority of fluconazole (200 mg/d) over amphotericin B (1 mg/kg/w) as maintenance therapy [24]. Fifteen percent of patients in the placebo arm developed CNS relapse compared with no relapses in the fluconazole group. Specific recommendations for the treatment of non-HIV-associated cryptococcal meningitis are summarized in table 1. For those individuals who are unable to tolerate fluconazole, itraconazole (200400 mg/day for 612 months) is an acceptable alternative. 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 extrapulmonary, non-CNS disease, resolution of symptoms and signs, as well as other markers of disease (e.g., radiographic abnormalities), is the desired outcome. Indeed, few studies have been conducted that specifically evaluate outcomes among HIV-infected patients with pulmonary or non-CNS disease. The etiologies of meningitis range in severity from benign and self-limited to life-threatening with potentially severe morbidity. Cryptococcal disease that develops in patients with HIV infection always warrants therapy. 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).

Examination findings that may indicate meningeal irritation include a positive Kernig sign, positive Brudzinski sign, neck stiffness, and jolt accentuation of headache (i.e., worsening of headache by horizontal rotation of the head two to three times per second). 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. For otherwise healthy hosts with CNS disease, standard therapy consists of amphotericin B, 0.71 mg/kg/d, plus flucytosine, 100 mg/kg/d, for 610 weeks. Options. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Fluconazole is well-tolerated; nausea, abdominal pain, and skin rash are the most common adverse effects. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. 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. Benefits and harms. 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). Fever, headache, neck stiffness, and altered mental status are classic symptoms of meningitis, and a combination of two of these occurs in 95% of adults presenting with bacterial meningitis.12 However, less than one-half of patients present with all of these symptoms.12,13, Presentation varies with age. Benefits and harms. These guidelines update the recommendations that were first released in 2018 on diagnosing, preventing, and managing cryptococcal disease. As the overall incidence of cryptococcal disease has increased so has the number of treatment options available to treat the disease. These cookies perform functions like remembering presentation options or choices and, in some cases, delivery of web content that based on self-identified area of interests. However, this is not possible in many areas of high incidence, and it should not delay diagnosis. You can review and change the way we collect information below. Recommendations. 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). Intrathecal or intraventricular amphotericin B may be used in refractory cases where systemic administration of antifungal therapy has failed. Most of the illness and deaths are estimated to occur in resource-limited countries, among people living with HIV. Drug acquisition costs are high for antifungal therapies administered for life. Meningitis can be caused by fungi, parasites, injury, or viral or bacterial infection. In addition, anemia occurs frequently and thrombocytemia occurs occasionally (possibly as a result of exposure to heparin). Cryptococcus neoformans is a fungus that lives in the environment throughout the world. Meningitis is an infection and inflammation of the meninges, which are the membranes that cover the brain and spinal cord. Two types of fungus can cause cryptococcal meningitis (CM). Acute bacterial meningitis must be treated right away with intravenous antibiotics and sometimes corticosteroids. Most people likely breathe in this microscopic fungus at some point in their lives but never get sick from it. The initial management strategy is outlined in Figure 1.7,9 Stabilization of the patient's cardiopulmonary status takes priority. Most common causes are bacterial or viral. Prospective clinical trials and carefully conducted observational studies show that potent antiretroviral therapy reduces the incidence of opportunistic infections [2527]. A fungus called C. neoformans causes most cases of CM. Elevated intracranial pressure is defined as opening pressure >200 mm H2O, measured with the patient in a reclining (lateral decubitus) position. Immunocompetent patients who present with mild-to-moderate symptoms should be treated with fluconazole, 200400 mg/d for 612 months [3, 4] (AIII). Yet, because of the potentially grave consequences of overlooking this illness, it is imperative to assess AIDS patients with pneumonia for possible fungal infection. Patients in the amphotericin B group had significantly more relapses, more drug-related adverse events, and more bacterial infections, including bacteremia [24]. 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. Before 1950, disseminated cryptococcal disease was uniformly fatal. Reprints or correspondence: Dr. Michael S. Saag, University of Alabama at Birmingham, 908 20th Street South, Birmingham, AL 35294-2050 (. Cookies used to track the effectiveness of CDC public health campaigns through clickthrough data. 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. Abstract. 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. Objectives. Management of Contacts: Investigation of contacts is not of practical value. 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. 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. Improving access to these tests is a key step in reducing deaths from cryptococcal meningitis. Costs. There is little to distinguish cryptococcal pneumonia from other causes of atypical pneumonia in HIV-infected patients. The clinicians index of suspicion should be guided by the prevalence of specific conditions in the community, as well as clinical judgment. Combination therapy of amphotericin B and flucytosine will sterilize CSF within 2 weeks of treatment in 60%-90% of patients [ 1, 3 ]. 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. Acetozolamide and mannitol have not been shown to provide any clear benefit in the management of elevated intracranial pressure resulting from cryptococcal meningitis (DIII). Costs. In cases of CNS mass lesions (cryptococcomas), radiographic resolution of lesions is the desired outcome. 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.. 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). This inflammation can produce a wide range of symptoms and, in extreme cases, cause brain damage, stroke, or even death. 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. Empiric antibiotics should be directed toward the most likely pathogens and should be adjusted by patient age and risk factors. Fluconazole consolidation therapy may be continued for as along as 612 months, depending on the clinical status of the patient. Benefits and harms. Cryptococcal meningitis.

Your doctor may also test your blood. 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 ).
