In a small, unvalidated retrospective analysis of 27 patients with HIV-associated cryptococcal meningoencephalitis who received fluconazole as initial therapy, 32 episodes of relapse were documented [50]. 76. Goldman-Cecil Medicine. Evidence summary. Induction therapy with AmBd (0.7–1 mg/kg per day IV), liposomal AmB (3–4 mg/kg per day IV), or ABLC (5 mg/kg per day IV) plus flucytosine (100 mg/kg per day orally in 4 divided doses) for at least 6 weeks (B-III). 16. Recombinant IFN-γ use remains uncertain (C-III). With rapid immune reconstitution in patients with cryptococcal meningitis, there is a risk of increased inflammatory response in the meninges that can lead to paradoxical worsening of the symptoms and, sometimes, death. Call your local emergency number or go to an emergency room if you suspect meningitis in a young child who has these symptoms: Centers for Disease Control and Prevention website. Corticosteroid treatment may be considered if ARDS is present in the context of IRIS (B-III). This treatment trial defined our preferred regimen of AmBd and flucytosine followed by fluconazole, as noted in the previous IDSA guidelines, and likely reflects differences in the pharmacokinetics, bioavailability, and drug interactions between the 2 azoles. An even higher dosage of 1.0 mg/kg per day IV of AmBd has been used for the initial 2 weeks in cryptococcal meningitis with good results but without any comparative data [169]. Two large, prospective, randomized, comparative trials showed that fluconazole is the most effective maintenance therapy [53]. Given the continuing high morbidity and mortality of cryptococcal meningoencephalitis in non–HIV-infected patients associated with suboptimal treatment regimens and the poor results of fluconazole alone for cryptococcal meningoencephalitis in HIV-infected patients, there is insufficient evidence to recommend fluconazole alone or combined with flucytosine as primary induction therapy for non–HIV-infected, nontransplant patients. After 2 weeks of therapy, CSF culture results were negative 9% more often in patients receiving AmBd plus flucytosine than in patients treated with AmBd alone (P=.06). When AmBd is given in resource-limited areas, frequent laboratory monitoring and fluid supplementation are still essential. 75. 51. For instance, in a recent study involving 62 patients coinfected with HIV and C. neoformans, MRI identified masses in 21% and dilated perivascular spaces in 46% [88]. Maintenance therapy is fluconazole (6 mg/kg per day orally) (A-II). Permanent ventriculoperitoneal (VP) shunts should be placed only if the patient is receiving or has received appropriate antifungal therapy and if more conservative measures to control increased intracranial pressure have failed. No clinical trials dedicated to children have been performed. 52. Because of its mechanism of action and animal model studies that show potential for teratogenicity, flucytosine is classified as a pregnancy class C drug and should be used with caution in pregnancy on a case-by-case basis. In addition, this trial demonstrated that the risk of relapse was increased if the patient had not received flucytosine during the initial 2 weeks of primary therapy for cryptococcal meningoencephalitis [54]. Although dissemination from an active pulmonary infection can occur in a nonimmunosuppressed patient, it is a much less likely occurrence than in immunocompromised patients. Recommendations for initial maintenance therapy have not changed since they were initially published. The other role for surgery in the immunocompetent patient population regards those patients who have persistent focal radiographic abnormalities despite conventional antifungal therapy. The most common symptoms are fever, headache, and neck stiffness. Nonetheless, extensive treatment studies with flucytosine in children have not been performed, and flucytosine-related myelosuppression has been reported in adult patients during the 2-week induction phase of therapy [160]. Emphasis has been placed on potential complications in management of cryptococcal infection, including increased intracranial pressure, immune reconstitution inflammatory syndrome (IRIS), drug resistance, and cryptococcomas. Evidence summary. These guidelines for its management have been built on the previous Infectious Diseases Society of America guidelines from 2000 and include new sections. IRIS may either occur early (ie, within a few days) or late after the introduction of HAART, sometimes up to several months thereafter. Philadelphia, PA: Elsevier; 2020:chap 262. Stable patients, presenting with cavitary or nodular lung lesions and in whom the infection is limited to the lungs may be treated with fluconazole at a dose of 400 mg orally per day for the duration of induction and consolidation phases. No events occurred during a median period of 26.1 months when patients were receiving both HAART and maintenance therapy for cryptococcal meningitis (0% incidence per 100 person-years). Untreated, adrenal insufficiency is fatal, and indeed this was invariably the case until the advent of synthetic cortisone in 1949. When possible, relapse isolate(s) from an area where resistance has been documented should undergo in vitro susceptibility testing. Routine in vitro susceptibility testing of C. neoformans isolates during initiation of therapy is not recommended for 2 principal reasons: (1) primary resistance to first-line antifungal drugs is not currently a significant clinical problem, and (2) in vitro susceptibility testing (including methods and breakpoints) for Cryptococcus species against azoles and AmB is not well validated. In a comparative study of 100 patients treated with liposomal AmB versus AmBd, the 2-week mycological success of liposomal AmB dosages between 3 mg/kg per day (64%) and 6 mg/kg per day (54%) was similar. This complication of increased intracranial pressure must be reduced without causing cerebral herniation. Cryptococcal CNS infection causes the typical symptoms and signs of meningitis. In cryptococcosis, IRIS can occur in 2 forms: (1) “unmasking” IRIS, in which cryptococcal symptoms first appear after the start of HAART; or (2) “paradoxical” IRIS during the treatment of cryptococcosis and administration of HAART. The most important issues are clinical identification and prevention, and finally, when it is causing severe disease, IRIS management requires the use of an anti-inflammatory strategy to prevent further host damage and not a change in direct antifungal drug(s). For AmBd toxicity issues, LFAmB may be substituted in the second 2 weeks. If so, these will need to be addressed in the therapeutic strategy after reinduction therapy. Intermittent AmBd should be reserved for patients who have had multiple relapses following azole therapy or who are intolerant of azoles. T.C.S. These complications may occur from this infection: Amphotericin B can have side effects such as: Call your local emergency number (such as 911) if you develop any of the serious symptoms listed above. Another oral drug, fluconazole, in high doses may also be effective. There is no general agreement on the timing of above, and there are no systematically collected data assessing effect of delay of re-initiating repeated lumbar punctures and other drainage procedures. AmBd dosages of 0.7 mg/kg per day with adjunctive saline infusions are generally well tolerated for 2 weeks [21, 27, 87], and toxicity issues with prolonged use can be averted in some cases by substituting LFAmB for AmBd in the second 2–4 weeks of induction therapy.

Amphotericin B (AmB) deoxycholate (AmBd; 0.7–1.0 mg/kg per day intravenously [IV]) plus flucytosine (100 mg/kg per day orally in 4 divided doses; IV formulations may be used in severe cases and in those without oral intake where the preparation is available) for at least 2 weeks, followed by fluconazole (400 mg [6 mg/kg] per day orally) for a minimum of 8 weeks (A-I). Lesions detected by CT are more common in apparently healthy hosts (>14%) than those compromised by AIDS (4%–5%) or for other reasons (10%) [110] and are usually associated with meningitis. Surgery should be considered for either diagnosis or persistent radiographic abnormalities and symptoms not responding to antifungal therapy (B-III). Since then, the strength of these guidelines has been supported by reports of adverse consequences when they are not followed [2, 92]. Multiple cryptococcomas require prolonged therapy, with or without corticosteroids. Recommendations for management also include other sites of infection, including strategies for pulmonary cryptococcosis. Itraconazole (200 mg twice per day orally) for 10–12 weeks (C-II), although use of this agent is discouraged. In severely immunosuppressed patients with nonresponding parenchymal brain mass, it is essential to consider that the mass may represent a second pathogen or tumor, and a brain biopsy or aspirate will be necessary for identification. Di Afrika, meningitis cryptococcal diperkirakan merupakan penyebab meningitis yang paling sering dijumpai dan ini mencakup 20–25% kematian yang berhubungan dengan AIDS di … In a subsequent trial for the treatment of AIDS-associated cryptococcal meningoencephalitis, a higher dosage of AmBd (0.7 mg/kg per day) was used, along with a lower dosage of flucytosine (100 mg/kg per day) [27] than earlier antifungal combination studies involving HIV-uninfected patients [28, 29]. A switch to fluconazole is appropriate after delivery. Although C. neoformans may be isolated from sputum samples of asymptomatic individuals [78], its identification in respiratory tract specimens in a transplant recipient should be considered as representing a pathogen and warrants an investigation for invasive pulmonary disease. Alternative therapy to AmBd is liposomal AmB (3–4 mg/kg per day) in patients with initial or developing renal dysfunction or who are receiving other nephrotoxic agents. There are also case reports of very low levels of proinflammatory cytokines (IFN-γ, tumor necrosis factor-α, and interleukin-6) and high levels of the anti-inflammatory cytokine interleukin-10 in C. gattii meningitis in nonimmunocompromised hosts that were associated with slowed clearance of cryptococcus from the CSF [117, 118]. 26th ed. Evidence summary. The median time to disease onset is 21 months after transplantation; 68.5% of the cases occur > 1 year after transplantation. Furthermore, the treatment of meningoencephalitis in HIV-infected individuals formalized the concept of induction, consolidation (clearance), and maintenance (suppression) phases in management of invasive mycoses in a severely immunosuppressed host. 66. A randomized trial in Thailand found severe metabolic acidosis and other complications associated with acetazolamide therapy and was stopped prematurely [97]. Normal or mildly increased in tuberculous meningitis; may be increased in fungal; AIDS patients with cryptococcal meningitis have increased risk of blindness and death unless kept below 300 mm H 2 O.

Cases of cryptococcosis-associated IRIS have also been reported as a complication in solid-organ transplant recipients [82] and in apparently healthy hosts [85]. 39. At annual intervals, the Expert Panel Chair, the SPGC liaison advisor, and the Chair of the SPGC will determine the need for revisions to the guideline on the basis of an examination of current literature. Because no significant comparative trials/studies have been conducted to evaluate “salvage therapy” for patients for whom primary therapy fails or who experience relapse after successful primary therapy, our recommendations are based solely on clinical experience/personal preference and several small, open trial studies with refractory disease. In a small prospective study of CNS cryptococcosis in transplant recipients, the median time to CSF sterilization was 10 days (mean, 16 days) [75]. Meningitis is a serious infection of the meninges in the brain or spinal cord that is most commonly viral or bacterial in origin, although fungal, parasitic, and noninfectious causes are also possible. The primary end point of this study was the rate of reduction in CSF cryptococcal colony-forming units (CFUs) from serial quantitative CSF cultures obtained on days 3, 7, and 14 of treatment. These tissues are called meninges. There are no prospective studies that specifically address the management of pulmonary cryptococcosis in any patient population but only retrospective surveys and anecdotal reports [78, 81, 88, 89, 122]. A recent study of 64 randomized HIV-infected patients with cryptococcal meningoencephalitis showed that AmBd at 1.0 mg/kg per day was more fungicidal than at 0.7 mg/kg per day with the use of flucytosine [30]. 59. All members of the Expert Panel participated in the preparation and review of the draft guideline. This necessitates higher dosages in children. Three options exist for antifungal maintenance therapy of AIDS-associated cryptococcal meningoencephalitis: (1) oral fluconazole (200 mg per day), (2) oral itraconazole (200 mg twice per day orally), or (3) AmBd (1 mg/kg per week IV). In all non–HIV-infected and in most HIV-infected patients receiving combination antifungal therapy with AmBd plus flucytosine, negative cultures at 2 weeks of therapy should be a goal. 62. In a very recent study of 143 randomized patients, the combination use of AmBd (0.7 mg/kg per day) plus fluconazole (800 mg per day) demonstrated satisfactory outcomes, compared with AmBd alone, and may be a reasonable approach to therapy in settings where flucytosine is not available or contraindicated [38].
