Meningitis Treatment & Management - Medscape 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. 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. In many cases, people need to continue taking fluconazole indefinitely. The presentation of pulmonary cryptococcosis can range from asymptomatic nodular disease to severe acute respiratory distress syndrome (ARDS). Ventriculoperitoneal shunts may become secondarily infected with bacteria; however, this is an uncommon complication. Author disclosure: No relevant financial affiliations.

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. Most common causes are viral or autoimmune. Your doctor will insert a needle and collect a sample of your spinal fluid. Dexamethasone should be administered to children and adults with suspected bacterial meningitis before or at the time of initiation of antibiotics. Youll probably also take flucytosine, another antifungal medication, while youre taking the amphotericin B. Cryptococcal meningitis: a review for emergency clinicians Patients with meningitis present a particular challenge for physicians. Infections and other disorders affecting the brain and spinal cord can activate the immune system, which leads to inflammation. 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. However, in patients with HIV or AIDS, the yearly incidence rate is between 2 and 7 cases per 1,000 people. The objective of treatment is eradication of the infection and control of elevated intracranial pressure. CSF examination and viral isolation or serology. 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]. Early, appropriate treatment of HIV-associated cryptococcal meningitis significantly reduces both the morbidity and mortality associated with this disorder.

If tuberculosis is unlikely and there are no AIIRs and/or respirators available, use Droplet Precautions instead of Airborne Precautions, Tuberculosis more likely in HIV-infected individual than in. After 10 weeks of therapy, the fluconazole dosage may be reduced to 200 mg/d, depending on the patient's clinical status. Copyright 2023 American Academy of Family Physicians. Patients typically present with fever and/or headache of gradual onset, which becomes progressively more debilitating. Your Guide to Salmonella Meningitis and How to Spot It, Group B Streptococcal (GBS) Meningitis: Symptoms, Treatment, Outlook, and More. An alternative regimen for AIDS-associated cryptococcal meningitis is amphotericin B (0.71 mg/kg/d) plus 5-flucytosine (100 mg/kg/d) for 610 weeks, followed by fluconazole maintenance therapy. 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. Considerations for Bioterrorist Threats, Table 4. Early, appropriate treatment of non-CNS pulmonary and extrapulmonary cryptococcosis reduces morbidity and prevents progression to potentially life-threatening CNS disease. CSF results can be variable, and decisions about treatment with antibiotics while awaiting culture results can be challenging. In addition, anemia occurs frequently and thrombocytemia occurs occasionally (possibly as a result of exposure to heparin).

Control Management of Cases: Enteric precautions are indicated for seven days after onset, unless a non-enteroviral diagnosis is established. The principal intervention for reducing elevated intracranial pressure is percutaneous lumbar drainage [21, 22] (AII). Recommendations. Combination therapy of amphotericin B and flucytosine will sterilize CSF within 2 weeks of treatment in 60%90% of patients [1, 3]. Because the goal is cure following cessation of therapy, patients requiring suppressive therapy for >12 years should be considered failures. A lumbar puncture is recommended after 2 weeks of treatment to assess the status of CSF sterilization. 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]. 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. Chemoprophylaxis of close contacts is helpful in preventing additional infections. To receive email updates about this page, enter your email address: We take your privacy seriously. 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.

Your doctor will monitor you closely while youre on this drug to watch for nephrotoxicity (meaning the drug can be toxic to your kidneys). 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.) 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. definitions. Classic symptoms of pneumonitis, including cough, fever, and sputum production, may be present, or pleural symptoms may predominate. Immunosuppressed patients, such as solid organ transplant recipients, require more prolonged therapy [3]. *Infection control professionals should modify or adapt this table according to local conditions. cryptococcal, or other . Aseptic meningitis is the most common form. Abstract.

These pathogens include enterohemorrhagicEscherichia coliO157:H7,Shigella spp,hepatitis A virus, noroviruses, rotavirus,C. difficile. It is necessary to carefully monitor serum electrolytes, renal function, and bone marrow function. When the CSF pressure is normal for several days, the procedure can be suspended. Recommendations. Regardless of the treatment chosen, it is imperative that all patients with pulmonary and extrapulmonary cryptococcal disease have a lumbar puncture performed to rule out concomitant CNS infection. Guidelines for diagnosing, preventing and managing cryptococcal disease Cookies used to track the effectiveness of CDC public health campaigns through clickthrough data. At approximately the same time, the incidence of cryptococcal infections rose dramatically, due in large part to the explosion of the AIDS epidemic around the world and the use of more potent immunosuppressive agents by increasing numbers of solid organ transplant recipients [4]. 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. In selected cases, susceptibility testing of the C. neoformans isolate may be beneficial to patient management, particularly if a comparison can be determined between baseline and sequential isolates. Combination therapy of amphotericin B and flucytosine will sterilize CSF within 2 weeks of treatment in 60%-90% of patients [ 1, 3 ]. 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. The desired outcome is resolution of abnormalities, such as fever, headache, altered mental status, meningeal signs, elevated intracranial pressure, and cranial nerve abnormalities.
