Specific recommendations for the treatment of non-HIV-associated cryptococcal meningitis are summarized in table 1. Oxford University Press is a department of the University of Oxford. Management of elevated intracranial pressure in HIV-infected patients with cryptococcal disease. Additional costs are accrued for monthly monitoring and supervision of therapies associated with most of the recommended regimens. Cryptococcal meningitis pathophysiology includes brain damage. 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 ). 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,. Preventing relapse of cryptococcosis reduces mortality and morbidity and slows the progression of HIV disease. 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. The antibiotic or combination of antibiotics depends on the type of bacteria causing the infection. 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 ). This fungus is found in soil all over the world. As is true for other systemic mycoses, treatment of disease due to C. neoformans have improved dramatically over the last 2 decades. However, it is also important to exclude cryptococcal meningitis in patients with seizures, bizarre behavior, confusion, progressive dementia, or unexplained fever. While awaiting the results of imaging studies, the serum should be tested for the presence of cryptococcal polysaccharide antigen. When the CSF pressure is normal for several days, the procedure can be suspended. According to the U.S. Centers for Disease Control and Prevention (CDC), infections by C. neoformans occur yearly in about 0.4 to 1.3 cases per 100,000 people in the general healthy population. Surgery should be considered for patients with persistent or refractory pulmonary or bone lesions. To further complicate the diagnostic process, physical examination and testing are limited in sensitivity and specificity. For those individuals who are unable to tolerate fluconazole, itraconazole (200400 mg/day for 612 months) is an acceptable alternative. Costs. Among HIV-negative patients, the benefit of steroid therapy is not well-established and should not be used (DIII). (2005). The etiologies of meningitis range in severity from benign and self-limited to life-threatening with potentially severe morbidity. Taking this medication helps prevent relapses. Treatment decisions should not be based routinely or exclusively on cryptococcal polysaccharide antigen titers in either the serum or CSF [31, 34] (AI). This disease is rare in healthy people. CDC twenty four seven. All Rights Reserved. Recognition of cryptococcal meningitis in HIV-infected patients requires a high index of suspicion. Specific recommendations for the treatment of non-HIV-associated cryptococcal pulmonary disease are summarized in table 1. Airborne plus Contact Precautions plus eye protection. You will be subject to the destination website's privacy policy when you follow the link. There are 2 key elements in preventing relapse of cryptococcal meningitis: (1) control of HIV replication by means of potent HAART and (2) the use of chronic antifungal therapy to prevent microbial relapse. 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. Therefore, the specific treatment of choice has not been fully elucidated. Cryptococcus gattii is a ubiquitous fungal pathogen that causes meningitis and pneumonia. Is There a Link Between Meningitis and COVID-19? 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. Medical approaches, including the use of corticosteroids, acetazolamide, or mannitol, have not been shown to be effective in the setting of cryptococcal meningitis. Cryptococcal meningitis is a fungal infection that usually affects people with a weakened immune system. A randomized comparative trial demonstrated the superiority of fluconazole (200 mg/d) over amphotericin B (1 mg/kg/w) as maintenance therapy [24]. Ventriculoperitoneal shunts may become secondarily infected with bacteria; however, this is an uncommon complication. With the exception of the typical skin lesions (which mimic molluscum contagiosum) associated with disseminated cryptococcosis, history, physical examination, or routine laboratory testing cannot elicit features suggestive of cryptococcal disease. It is associated with a variety of complications including disseminated disease as well as neurologic complications . Patients with a positive culture at 2 weeks may require a longer course of induction therapy. Youll probably also take flucytosine, another antifungal medication, while youre taking the amphotericin B. 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. 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. 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. Outcomes. Use eye/face protection if aerosol-generating procedure performed or contact with respiratory secretions anticipated. 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.) Cryptococcal antigen, a biological marker that indicates a person has cryptococcal infection, can be detected in the body weeks before symptoms of meningitis appear. For both immunocompetent and immunocompromised patients with significant renal disease, lipid formulations of amphotericin B may be substituted for amphotericin B during the induction phase [12] (CIII). These essential medications are often unavailable in areas of the world where they are most needed. Among patients with AIDS- associated cryptococcal meningitis who are treated successfully, there is a high risk of relapse in the absence of maintenance therapy. 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. The differential diagnosis is broad (Table 1). 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). Treatment should be started promptly in cases where transfer, imaging, or lumbar puncture may slow a definitive diagnosis. This fungus is found in soil around the world. Pilot studies that have investigated fluconazole with flucytosine as initial therapy yielded unsatisfactory outcomes [7]. Patients in the amphotericin B group had significantly more relapses, more drug-related adverse events, and more bacterial infections, including bacteremia [24].

Search dates: October 1, 2016, and March 13, 2017. Because the goal is cure following cessation of therapy, patients requiring suppressive therapy for >12 years should be considered failures. 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. There are two meningitis vaccines available in the US, and both are proven safe. The lung is the principal route of entry for infection. Defining the presence of meningitis and its severity is essential; there is no adequate substitute for examination of the CSF. But the conditional rarely occurs in someone who has a normal immune system. CDC twenty four seven. 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. 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. 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. Benefits and harms. Your doctor will insert a needle and collect a sample of your spinal fluid. Therefore, initial therapy with fluconazole, even among low risk patients, is discouraged (DIII). 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. Options. Aggressive antiretroviral therapy should be administered in accordance with standards of care in the community [35].

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. Introduction: Cryptococcal Meningitis (CM) remains a high-risk clinical condition, and many patients require emergency department (ED) management for complications and stabilization. Aseptic meningitis is the most common form. Standard Precautions Recommendations, Table 5. In addition, anemia occurs frequently and thrombocytemia occurs occasionally (possibly as a result of exposure to heparin). The most troublesome toxic side effect is renal injury, including elevation of the serum creatinine, hypokalemia, hypomagnesemia, and renal tubular acidosis. We avoid using tertiary references.
