Abstract
Background Emerging risk factors highlight the need for an updated understanding of cryptococcosis in the United States. Objective Describe the epidemiological trends and clinical outcomes of cryptococcosis in three patient groups: people with HIV (PWH), non-HIV-infected and non-transplant (NHNT) patients, and patients with a history of solid organ transplantation. Methods We utilized data from the Merative Medicaid Database to identify individuals aged 18 and above with cryptococcosis based on the International Classification of Diseases, Tenth Revision diagnosis codes from January 2017 to December 2019. Patients were stratified into PWH, NHNT patients, and transplant recipients according to Infectious Diseases Society of America guidelines. Baseline characteristics, types of cryptococcosis, hospitalization details, and in-hospital mortality rates were compared across groups. Results Among 703 patients, 59.7% were PWH, 35.6% were NHNT, and 4.7% were transplant recipients. PWH were more likely to be younger, male, identify as Black, and have fewer comorbidities than patients in the NHNT and transplant groups. Notably, 24% of NHNT patients lacked comorbidities. Central nervous system, pulmonary, and disseminated cryptococcosis were most common overall (60%, 14%, and 11%, respectively). The incidence of cryptococcosis fluctuated throughout the study period. PWH accounted for over 50% of cases from June 2017 to June 2019, but this proportion decreased to 47% from July to December 2019. Among the 52% of patients requiring hospitalization, 61% were PWH and 35% were NHNT patients. PWH had longer hospital stays. In-hospital mortality at 90 days was significantly higher in NHNT patients (22%) compared to PWH (7%) and transplant recipients (0%). One-year mortality remained lowest among PWH (8%) compared to NHNT patients (22%) and transplant recipients (13%). Conclusion In this study, most cases of cryptococcosis were PWH. Interestingly, while the incidence remained relatively stable in PWH, it slightly increased in those without HIV by the end of the study period. Mortality was highest in NHNT patients.

Therapeutic lumbar puncture and lumbar drainage: which is more effective for the management of intracranial hypertension in HIV patients with cryptococcal meningitis? Results of a prospective non-randomized interventional study in China. Curr Med Res Opin 2022; 38:803-810.

Abstract
OBJECTIVE This study aimed to evaluate the effectiveness of therapeutic lumbar drainage (LD) compared to therapeutic lumbar puncture (LP) for the management of intracranial hypertension (ICH) among HIV-positive patients with cryptococcal meningitis (CM). METHODS The study was a multicenter prospective non-randomized interventional clinical trial. One hundred and sixteen HIV-associated CM patients were identified who presented with ICH (≥250 mmH2O). The LP group comprised 76 cases, while the LD group consisted of 40 cases. We compared mortality, intracranial pressure (ICP) normalization rate, and clinical symptom remission at 10 weeks, between the two groups. RESULTS The cumulative mortality at week 10 was 22.4% in the LP group and 20% in the LD group (p = .927), without any significant difference in mortality between the two groups. Improvement after treatment at 2-weeks, ICP normalization, and headache reversal event occurrence in the two groups showed no significant difference (p > .05). The incidence of CSF Cryptococcus clearance at two weeks in the LD group was significantly higher than in the LP group (p < .05). The frequency of invasive lumbar therapeutic procedures in the LP group during the first week was higher than that of the LD group (p < .05). Localized infection at the puncture site occurred more frequently in the LD group than in the LP group (p < .05). CONCLUSION For HIV-positive CM patients with an elevated ICP, LD and LP are comparably effective and safe options to normalize ICP. LP increases the frequency of invasive lumbar therapeutic procedures but does not incur more risk of infection events at the puncture site, while LD may accelerate CSF Cryptococcus clearance but may induce more frequent localized infection. TRIAL REGISTRATION This study was registered as one of 12 trials under a general project at the Chinese Clinical Trial Registry (ChiCTR1900021195).

Abstract
Background Cryptococcal meningitis (CM) remains a leading cause of death in HIV-infected patients, despite advances in CM diagnostic and therapeutic strategies. This study was performed with the aim to develop and validate a novel scoring model to predict mortality risk in HIV-infected patients with CM (HIV/CM). Methods Data on HIV/CM inpatients were obtained from a Multicenter Cohort study in China. Independent risk factors associated with mortality were identified based on data from 2013 to 2017, and a novel scoring model for mortality risk prediction was established. The bootstrapping statistical method was used for internal validation. External validation was performed using data from 2018 to 2020. Results We found that six predictors, including age, stiff neck, impaired consciousness, intracranial pressure, CD4+ T-cell count, and urea levels, were associated with poor prognosis in HIV/CM patients. The novel scoring model could effectively identify HIV/CM patients at high risk of death on admission (area under curve 0.876; p<0.001). When the cut-off value of 5.5 points or more was applied, the sensitivity and specificity was 74.1 and 83.8%, respectively. Our scoring model showed a good discriminatory ability, with an area under the curve of 0.879 for internal validation via bootstrapping, and an area under the curve of 0.886 for external validation. Conclusions Our developed scoring model of six variables is simple, convenient, and accurate for screening high-risk patients with HIV/CM, which may be a useful tool for physicians to assess prognosis in HIV/CM inpatients.

Abstract
BACKGROUND Cryptococcal meningitis (CM) is the most serious presentation of invasive cryptococcosis. Seen in patients with and without HIV infection, CM is associated with significant morbidity and mortality. Early lumbar puncture is a cornerstone of treatment in cryptococcal meningitis. We present findings from a nationwide analysis of patients admitted with CM in the United States between 2007 and 2016, with the aim of determining the impact of delays in lumbar puncture on inpatient outcomes. METHODS The national inpatient sample (NIS) database was queried for all inpatient visits for cryptococcal meningitis between January 2007 and December 2016. Logistic regression models were used to determine risk factors for inpatient mortality, prolonged admissions, and delays in obtaining an initial lumbar puncture. RESULTS The annual number of admissions for CM decreased during the study interval, from 3590 in 2007 to 2830 in 2016. Mortality did not change over this period (9.9%); however, length of stay and inpatient cost significantly increased. The proportion of patients with HIV declined from 70.7% to 54.0%. Delay in lumbar puncture beyond the first 24 h was independently associated with mortality (OR = 1.55, CI = 1.31-1.82, p-value <.001). Patients admitted on a weekend, those of African-American ethnicity, and those without a known history of HIV were more likely to have delays in obtaining an early LP. HIV patients had a lower risk of mortality (OR = 0.77, CI = 0.68-0.86, p-value <.001). CONCLUSION We found an independent association of delay in early lumbar puncture with worsened patient outcomes. Inpatient mortality for patients with CM continues to remain high, with an increasing proportion of patients without underlying HIV infection. There were significant deviations in management of CM from Infectious Diseases Society of America (IDSA) guidelines.

Abstract
BACKGROUND The indications for lumbar puncture in non-HIV-infected, non-transplant (NHNT) patients with cryptococcosis without meningeal signs need to be more fully defined. OBJECTIVES This study was designed to determine the optimal predictors of central nervous system (CNS) involvement in adult NHNT patients with cryptococcosis. METHODS The study population consisted of adult NHNT patients with culture-confirmed cryptococcosis who sought care at a university hospital in Taiwan from 2002 to 2016. We used a case-control method to identify the clinical characteristics and laboratory findings associated with CNS involvement in patients who underwent a diagnostic lumbar puncture. In the sensitivity analysis, we included additional control patients who did not undergo lumbar puncture, but were followed beyond 12 months without the development of CNS involvement in the absence of exposure to any fungicidal agents. RESULTS We entered 270 NHNT adult patients into the study during the 15-year period. CNS involvement was confirmed in 66 (71.0%) of 93 patients who underwent lumbar puncture. A multivariable analysis revealed that presence of neurological manifestations and elevated serum CRAG titers were independently associated with a 23.97-fold (95% confidence interval [CI], 4.37-182.23) and 1.53-fold (per 2-fold increment, 95% CI 1.26-1.92) increased odds ratio for CNS involvement, respectively. Headache and focal neurologic signs were independently associated with CNS involvement. A cut-off serum CRAG titer of ≥1:64 provided the highest diagnostic performance by Youden index (sensitivity 83% and specificity 65%). Similar findings were noted in the sensitivity analysis including 198 (73%) patients. CONCLUSION Lumbar puncture is indicated for NHNT patients with cryptococcosis who have neurologic manifestations or a serum CRAG titer of ≥1:64.

Abstract
Cryptococcal meningitis is a potentially devastating infectious complication of immunosuppression best characterized in individuals with HIV. Early recognition of and appropriate antifungal therapy for cryptococcal meningitis has a profound effect on outcomes, but with more varied presentations in well-resourced countries recognition may be delayed. We present four cases of cryptococcal meningitis in immunosuppressed patients, each with significant delays in diagnosis. Pulling from recollections of providers and the documented chart assessments, we discuss and tabulate the cognitive biases and diagnostic errors that contributed to delay. We further explore the knowledge deficits regarding cryptococcal meningitis that appeared in these cases. Once meningitis was considered, each of these cases of cryptococcal meningitis was rapidly diagnosed. Diagnostic delay was driven by knowledge deficits, followed by common biases such as availability heuristics and premature closing. These delays could be countered by maintaining broad differential diagnoses, re-evaluating the patient presentation after recognition of immunosuppression, and early consultation of specialists. Delay in diagnosis of cryptococcal meningitis is associated with high morbidity and mortality. By exploring the various case presentations and errors made, we hope to provide a counter to some of the knowledge deficits associated with cryptococcal meningitis, and to provide actionable advice for early consultation to infectious disease specialists in order to improve outcomes.

Abstract
These updated guidelines from the Infectious Diseases Community of Practice of the American Society of Transplantation review the diagnosis, prevention, and management of cryptococcosis in the pre- and post-transplant period. The current update now includes a discussion of cryptococcosis, which is the third most common invasive fungal infection in SOT recipients. Infection often occurs a year after transplantation; however, early infections occur and donor-derived infections have been described within 3 months after transplant. There are two main species that cause infection, Cryptococcus neoformans and C gattii. Clinical onset may be insidious, but headaches, fevers, and mental status changes should warrant diagnostic testing. The lateral flow cryptococcal antigen assay is now the preferred test from serum and cerebrospinal fluid due to its rapidity, accuracy, and cost. A lumbar puncture with measurement of opening pressure is recommended for patients with suspected or proven cryptococcosis. Lipid amphotericin B plus 5-flucytosine is used as initial treatment of meningitis, disseminated infection, and moderate-to-severe pulmonary infection, followed by fluconazole as consolidation therapy. Fluconazole is effective for mild-to-moderate pulmonary infection. Immunosuppression reduction as part of management may lead to immune reconstitution syndrome that may resemble active disease.

Abstract
Cryptococcocis is an opportunistic fungal infection with high morbidity and mortality. Guidelines to aid clinicians regarding diagnosis, management, and treatment can be extensive and challenging to comply with. There is no tool to measure guideline adherence. To create such a tool, we reviewed current guidelines from the Infectious Diseases Society of America, the World Health Organization, the American Society of Transplantation, and recent significant publications to select the strongest recommendations as vital components of our scoring tool. Items included diagnostic tests (blood, tissue, and cerebrospinal fluid cultures, Cryptococcus antigen, India ink, histopathology with special fungal stains, central nervous system imaging), pharmacological (amphotericin B, flucytosine, azoles) and nonpharmacological treatments (intracranial pressure management, immunomodulation, infectious disease consultation), and follow-up of central nervous system complications. The EQUAL Cryptococcus Score 2018 weighs and aggregates the recommendations for the optimal management of cryptococcosis. Providing a tool that could measure guideline adherence or facilitate clinical decision-making.

Abstract
Background An infectious disease (ID) consultation is often obtained to treat patients with cryptococcosis due to the complex nature of the disease, but has never been demonstrated to impact outcomes. Methods We assembled a retrospective cohort of 147 consecutive cases of cryptococcosis in patients without HIV. Patients who were diagnosed less than 24 hours prior to death were excluded. Survival analysis was performed with Cox regression with survival censored past 90 days. Results The patients with an ID consult had a higher fungal burden but a lower 90-day mortality compared to patients without ID involvement (27% vs 45%, p<0.001), with an adjusted hazard ratio of not receiving an ID consult of 4.1 (95% CI: 2.2, 7.6). The ID consult group was more likely to receive an indicated lumbar puncture (86% vs 32%, p<0.001), and more likely to be treated with amphotericin B (AmB) (87% vs 24%, p<0.001) and flucytosine (5-FC) (57% vs 16%, p<0.001) when indicated. The duration of therapy with AmB (14 vs 11 days, p=0.05) and 5-FC (7.5 vs 1 days, p<0.001) was longer in the ID consult group. Conclusions Patients that received an ID consult were significantly less likely to die in the 90 days following diagnosis. Patients seen by ID physicians were more likely to be managed according to evidence based practice established by randomized controlled trials and published in IDSA guidelines. These data suggest that an ID consult should be an integral part of clinical care of patients with cryptococcosis.

Abstract
Cryptococcal meningitis (CM) is a common opportunistic infection with a high mortality rate in human immunodeficiency virus (HIV)-infected patients. It is unclear whether mannitol could be used to manage neurological symptoms in HIV-associated CM. Here, we retrospectively analyzed the clinical data of 33 patients with HIV-associated symptomatic CM at our hospital where mannitol was used to relieve neurologic symptoms. With the empirical mannitol therapy, patients had a median of 2 episodes (range, 1-6 episodes) of headaches the day at the starting of anti-cryptococcal therapy. The median score of pain intensity assessed by numerical rating scales was 7-point (range, 4-8 points). After the administration of mannitol, the score of pain intensity was reduced to 3-point or less. Three weeks after anti-cryptococcal therapy, 75.8% (25/33) of the patients did not report headaches. During the initial 3 weeks of anti-cryptococcal therapy, 13 patients had a total of 42 episodes of seizures. 97.6% (41/42) of the episodes of seizures were controlled after the administration of mannitol. Overall, 87.9% (29/33) of the patients survived more than 10 weeks without the need of therapeutic cerebrospinal fluid drainage. Mannitol was used for median of 26 days (range, 1-85 days) in these 29 patients. One patient had permanent vision loss. This study indicates that mannitol may possibly relieve neurologic symptoms in HIV-associated CM. It is worth re-revaluating the role of mannitol administration as a symptom control strategy in mild cases of HIV-associated CM.

Abstract
OBJECT Patients with cryptococcal meningitis often develop symptomatic intracranial hypertension. The need for permanent CSF diversion in these cases remains unclear. METHODS Cases of cryptococcal meningitis over a 5-year period were reviewed from a single, large teaching hospital. Sources of identification included ICD-9 codes, operative logs, and microscopy laboratory records. RESULTS Fifty cases of cryptococcal meningitis were identified. Ninety-eight percent (49/50) of patients were HIV positive. Opening pressure on initial lumbar puncture diagnosing cryptococcal meningitis was elevated (> 25 cm H2O) in 33 cases and normal (≤ 25 cm H2O) in 17 cases. Thirty-eight patients ultimately developed elevated opening pressure over a follow-up period ranging from weeks to years. Serial lumbar punctures for relief of intracranial hypertension were performed in 29 cases. Thirteen of these patients ultimately had shunting procedures performed after failing to improve clinically. Two factors were significantly associated with the need for shunting: patients undergoing shunt placement were more likely to be women (5/13 vs 0/16; p = 0.01) and to have a pattern of increasing CSF cryptococcal antigen (10/13 vs 3/16 cases; p = 0.003). All patients re-presenting with mycological relapse either underwent or were offered shunt placement. CONCLUSIONS Neurosurgeons are often asked to consider CSF diversion in cases of cryptococcal meningitis complicated by intracranial hypertension. Most patients do well with serial lumbar punctures combined with antifungal therapy. When required, shunting generally provided sustained relief from intracranial hypertension symptoms. Ventriculoperitoneal shunts are the favored method of diversion. To the authors' knowledge, the present study is the largest series on diversionary shunts in primarily HIV-positive patients with this problem.

Abstract
BACKGROUND Screening individuals with AIDS for serum cryptococcal antigen (CrAg), followed by treatment of CrAg positives with antifungals, may prevent cryptococcal meningitis. This review examined data on CrAg screening and treatment in resource-limited settings. METHODS We searched articles published during 2007-2014 on the effectiveness and cost-effectiveness of CrAg screening and treatment on the outcomes of mortality, morbidity, retention in care, quality of life, and/or prevention of ongoing HIV transmission. We rated overall quality of individual articles, summarized the body of evidence, the expected impact, and cost-effectiveness for each outcome. RESULTS We identified 2613 articles. Eight met all inclusion criteria. Five studies addressed mortality and/or morbidity outcomes; all were observational and had small sample sizes; 3 lacked a comparison group. Ratings of study quality ranged from "medium" to "weak," and the quality of the overall body of evidence for mortality and morbidity outcomes was rated as "fair." The intervention's expected impact on mortality and morbidity was rated as "moderate." The 4 cost-effectiveness studies included in the analysis showed that CrAg screening and treatment interventions are highly cost-effective. No studies addressed retention in care, quality of life, or HIV transmission. CONCLUSIONS Although limited, the body of evidence regarding CrAg screening and treatment suggests that the intervention may have an impact on preventing cryptococcal meningitis and death in persons with AIDS. Additional research is needed to quantify the intervention's effectiveness and identify optimal treatment dosing and implementation best practices.

Abstract
INTRODUCTION Cryptococcosis is an opportunistic mycosis, especially in patients that are human immunodeficiency virus (HIV)-positive, and frequently involves the central nervous system. METHODS We assessed the potential of ventriculoperitoneal shunting (VPS) in preventing mortality due to uncontrollable intracranial hypertension (ICH) in 15 patients with acquired immunodeficiency syndrome (AIDS)-related cryptococcal meningitis. RESULTS After 2 weeks of antifungal therapy consisting of amphotericin B deoxycholate with or without fluconazole, patients with persistent ICH underwent VPS, despite having persistent Cryptococcus neoformans infection. In 12 patients, the uncontrollable ICH was resolved by VPS. CONCLUSIONS Patients with cryptococcal meningoencephalitis who have ICH must be considered for VPS even with positive cerebrospinal fluid cultures.

Abstract
Background Despite the development of context-specific guidelines, cryptococcal meningitis (CCM) remains a leading cause of death amongst HIV-infected patients. Results from clinical audits in routine practice have shown critical gaps in clinicians’ adherence to recommendations regarding the management of CCM. Aim The aim of this study was to review the acute management of CCM at an urban district hospital in KwaZulu-Natal, South Africa with a view to making recommendations for improving care. Setting An urban district hospital in KwaZulu-Natal, South Africa. Methods A retrospective audit was performed on clinical records of all patients (age > 13 years) admitted to the hospital with a diagnosis of CCM between June 2011 and December 2012. Results Measurement of cerebrospinal fluid opening pressure at initial lumbar puncture (LP) was done rarely and only 23.4% of patients had therapeutic LPs. The majority of patients (117/127; 92.1%) received amphotericin B, however, only 19 of the 117 patients (16.2%) completed the 14-day treatment target. Amphotericin B-toxicity monitoring and prevention was suboptimal; however, in-patient referral for HIV counselling and testing was excellent. Conclusions The quality of care of CCM based on selected process criteria showed gaps in routine care at the hospital despite the availability of context-specific guidelines. An action plan for improving care was developed based on stakeholders’ feedback. A repeat audit should be conducted in the future in order to evaluate the impact of this plan and to ensure that improvements are sustained.

Accuracy of noninvasive intraocular pressure or optic nerve sheath diameter measurements for predicting elevated intracranial pressure in cryptococcal meningitis.

Abstract
Intraocular pressure measurement by tonometry and optic nerve sheath diameter measurement by ultrasound have imprecise but statistical correlation with intracranial pressure. Neither technique is an effective surrogate measure of intracranial pressure in cryptococcal meningitis; manometry should be used. Background Cryptococcal meningitis is associated with increased intracranial pressure (ICP). Therapeutic lumbar puncture (LP) is recommended when the initial ICP is >250 mm H2O, yet the availability of manometers in Africa is limited and not always used where available. We assessed whether intraocular pressure could be a noninvasive surrogate predictor to determine when additional therapeutic LPs are necessary. Methods Ninety-eight human immunodeficiency virus-infected Ugandans with suspected meningitis (81% Cryptococcus) had intraocular pressure measured using a handheld tonometer (n = 78) or optic nerve sheath diameter (ONSD) measured by ultrasound (n = 81). We determined the diagnostic performance of these methods for predicting ICP vs a standard manometer. Results The median ICP was 225 mm H2O (interquartile range [IQR], 135–405 mm H2O). The median intraocular pressure was 28 mm Hg (IQR, 22–37 mm Hg), and median ultrasound ONSD was 5.4 mm (IQR, 4.95–6.1 mm). ICP moderately correlated with intraocular pressure (ρ = 0.45, P < .001) and with ultrasound ONSD (ρ = 0.44, P < .001). There were not discrete threshold cutoff values for either tonometry or ultrasound ONSD that provided a suitable cutoff diagnostic value to predict elevated ICP (>200 mm H2O). However, risk of elevated ICP >200 mm H2O was increased with an average intraocular pressure >28 mm Hg (relative risk [RR] = 3.03; 95% confidence interval [CI], 1.55–5.92; P < .001) or an average of ONSD >5 mm (RR = 2.39; 95% CI, 1.42–4.03; P = .003). As either intraocular pressure or ONSD increased, probability of elevated ICP increased (ie, positive predictive value increased). Conclusions Noninvasive intraocular pressure measurements by tonometry or ultrasound correlate with cerebrospinal fluid opening pressure, but both are a suboptimal replacement for actual ICP measurement with a manometer.

Abstract
PURPOSE To evaluate the relationship between intracranial hyperpressure (HICP) and mortality in patients with cryptococcal meningitis related to AIDS (CMRA). METHODS This was an observational retrospective study. Patients were treated according to the Infectious Diseases Society of America recommendations during the evaluation period (days 0, 3, 5 and after hospitalization). High intracranial pressure (HICP) was defined as ICP values of C250 mm H20. The correlation between HICP and mortality at each of the three time points considered was investigated. Statistical analysis on the descriptive parameters and on the probability of a "death" event (odds ratio, OR) at each of those three time points was performed using the statistical software program Epidata. RESULTS Eighty patients were included in this study, of whom 53 (66.25 %) were male. The average age of the patients was 37.5 ± 8.1 (range 22–55) years. The median CD4?lymphocyte cell count was 35 (range 0–367) cells/ml. Among the entire patient cohort, 53 patients had a favorable outcome, and the mortality rate was 33.75 %. At baseline (day 0), 57 subjects (71.5 %) presented HICP, and these patients had a higher mortality rate than those with a normal ICP, but the difference did not reach statistical significance[OR 1.65, 95 % confidence interval (CI) 0.56–4.84]. On day 3, 41 of the patients presented HICP, and HICP at this timepoint was significantly associated with an increased risk of mortality (OR 4.35, 95 % CI 1.56–12.09). On day 5, 35(43.5 %) patients presented HICP, and HCIP at this time point was also significantly associated with higher mortality (OR 7.23, 95 % CI 2.53–20.14). CONCLUSION The results of this study confirm an association between HICP and mortality in patients with CMRA and indicate that the control of ICP during the first 5 days of hospitalization is more important than managing HICP only at baseline.

Abstract
Intracranial pressure management with repeat lumbar puncture (LP) was investigated in patients with cryptococcal meningitis in sub-Saharan Africa. Conducting at least 1 additional LP soon after cryptococcal diagnosis was related to decreased risk of acute mortality regardless of initial pressure. Introduction. Cryptococcal meningitis is the most common cause of adult meningitis in sub-Saharan Africa. Raised intracranial pressure (ICP) is common in cryptococcosis. Prior studies suggest elevated ICP is associated with mortality, and guidelines recommend frequent lumbar punctures (LPs) to control ICP. However, the magnitude of the impact of LPs on cryptococcal-related mortality is unknown. Methods. In sum, 248 individuals with human immunodeficiency virus (HIV)-associated cryptococcal meningitis, screened for the Cryptococcal Optimal ART Timing (COAT) trial in Uganda and South Africa, were observed. Individuals received an LP to diagnose meningitis, and subsequent therapeutic LPs were recommended for elevated ICP (>250 mmH2O) or new symptoms. We compared survival, through 11 days, between individuals receiving at least 1 therapeutic LP with individuals not receiving therapeutic LPs. The COAT trial randomized subjects at 7–11 days; thus, follow-up stopped at time of death, randomization, or 11 days. Results. Seventy-five (30%) individuals had at least 1 therapeutic LP. Individuals receiving therapeutic LPs had higher cerebrospinal fluid (CSF) opening pressures, higher CSF fungal burdens, and were more likely to have altered mental status at baseline than those with no therapeutic LPs. Thirty-one deaths (18%) occurred among 173 individuals without a therapeutic LP and 5 deaths (7%) among 75 with at least 1 therapeutic LP. The adjusted relative risk of mortality was 0.31 (95% confidence interval: .12–.82). The association was observed regardless of opening pressure at baseline. Conclusions. Therapeutic LPs were associated with a 69% relative improvement in survival, regardless of initial intracranial pressure. The role of therapeutic LPs should be reevaluated.

Abstract
Although the incidence of HIV-associated cryptococcosis has decreased in developed countries since the introduction of antiretroviral therapy, this disease continues to cause significant morbidity and mortality in sub-Saharan Africa among patients with AIDS. Important strides have been made in an attempt to decrease the burden of disease, particularly the development of the lateral flow assay cryptococcal antigen (LFA CrAg) as a diagnostic tool in resource-limited settings, coupled with the introduction of pre-emptive treatment with fluconazole for HIV-positive patients at risk for cryptococcosis with a positive LFA CrAg. Among solid organ transplant recipients, recent prospective studies have identified cryptococcosis as the third most common invasive fungal infection, and progress is being made toward earlier diagnosis and more effective therapy. Finally, the Cryptococcus gattii outbreak in British Columbia, Canada and the US Pacific Northwest is providing important new insights into the emergence of this pathogen in geographic areas previously considered low risk for acquisition of infection. Understanding the similarities and differences among C. gattii and C. neoformans infections will provide critical insights into the behavior of these organisms in the human host. Both pathogens affect immunocompetent and immunosuppressed hosts, causing pulmonary, central nervous system and widely disseminated infections. Treatment recommendations in the future will necessarily take into account the site of infection, clinical severity of the infection, Cryptococcus species, host immune status and economic resources.

Abstract
Central nervous system (CNS) infections in cancer patients present a diagnostic and therapeutic challenge for clinicians. While CNS infections are not frequent complications of cancer, its therapies, or hematopoietic stem cell transplantation, the importance of CNS infections lies in their propensity to result in profound morbidity and substantial mortality in this vulnerable patient population. With an expanding population of patients with malignant disease undergoing more potent and aggressive therapies and with the advent of newer immunomodulatory agents, the incidence of CNS infectious complications is likely to rise. This chapter will summarize the clinical and diagnostic evaluation of potential infections of the CNS in these patients and will discuss particular pathogens of interest with regard to this at-risk patient population.

Abstract
Latin America is the region with the third most AIDS-related cryptococcal meningitis infections globally. Highly active antiretroviral therapy (HAART) has reduced the number of infections; however, the number of deaths and the case-fatality rate continues to be unacceptable. In this review, we focus on the burden of AIDS-related cryptococcosis in Latin America and discuss potential strategies to reduce early mortality from Cryptococcus. In this review, we highlight the importance of: (1) earlier HIV diagnosis and HAART initiation with retention-in-care to avoid AIDS; (2) pre-HAART cryptococcal antigen (CRAG) screening with preemptive fluconazole treatment; (3) better diagnostics (e.g. CRAG testing); and (4) optimal treatment with aggressive management of intracranial pressure and induction therapy with antifungal combination. Implementation of these strategies can reduce cryptococcal-related deaths, improve care, and reduce healthcare costs.

Abstract
Invasive fungal infections are a major problem in solid organ transplant (SOT) recipients. Overall, the most common fungal infection in SOT is candidiasis, followed by aspergillosis and cryptococcosis, except in lung transplant recipients, where aspergillosis is most common. Development of invasive disease hinges on the interplay between host factors (e.g., integrity of anatomical barriers, innate and acquired immunity) and fungal factors (e.g., exposure, virulence and resistance to prophylaxis). In this article, we describe the epidemiology and clinical features of the most common fungal infections in organ transplantation. Within this context, we review recent advances in diagnostic modalities and antifungal chemotherapy, and their impact on evolving prophylaxis and treatment paradigms.

Cryptococcal meningitis treatment strategies in resource-limited settings: a cost-effectiveness analysis. PLoS Med 2012; 9:e1001316.

Abstract
BACKGROUND Cryptococcal meningitis (CM) is the most common form of meningitis in Africa. World Health Organization guidelines recommend 14-d amphotericin-based induction therapy; however, this is impractical for many resource-limited settings due to cost and intensive monitoring needs. A cost-effectiveness analysis was performed to guide stakeholders with respect to optimal CM treatment within resource limitations. METHODS AND FINDINGS We conducted a decision analysis to estimate the incremental cost-effectiveness ratio (ICER) of six CM induction regimens: fluconazole (800-1,200 mg/d) monotherapy, fluconazole + flucytosine (5FC), short-course amphotericin (7-d) + fluconazole, 14-d of amphotericin alone, amphotericin + fluconazole, and amphotericin + 5FC. We computed actual 2012 healthcare costs in Uganda for medications, supplies, and personnel, and average laboratory costs for three African countries. A systematic review of cryptococcal treatment trials in resource-limited areas summarized 10-wk survival outcomes. We modeled one-year survival based on South African, Ugandan, and Thai CM outcome data, and survival beyond one-year on Ugandan and Thai data. Quality-adjusted life years (QALYs) were determined and used to calculate the cost-effectiveness ratio and ICER. The cost of hospital care ranged from $154 for fluconazole monotherapy to $467 for 14 d of amphotericin + 5FC. Based on 18 studies investigating outcomes for HIV-infected individuals with CM in resource-limited settings, the estimated mean one-year survival was lowest for fluconazole monotherapy, at 40%. The cost-effectiveness ratio ranged from $20 to $44 per QALY. Overall, amphotericin-based regimens had higher costs but better survival. Short-course amphotericin (1 mg/kg/d for 7 d) with fluconazole (1,200 mg/d for14 d) had the best one-year survival (66%) and the most favorable cost-effectiveness ratio, at $20.24/QALY, with an ICER of $15.11 per additional QALY over fluconazole monotherapy. The main limitation of this study is the pooled nature of a systematic review, with a paucity of outcome data with direct comparisons between regimens. CONCLUSIONS Short-course (7-d) amphotericin induction therapy coupled with high-dose (1,200 mg/d) fluconazole is "very cost effective" per World Health Organization criteria and may be a worthy investment for policy-makers seeking cost-effective clinical outcomes. More head-to-head clinical trials are needed on treatments for this neglected tropical disease. Please see later in the article for the Editors' Summary.

Abstract
The introduction of several new antifungals has significantly expanded both prophylaxis and treatment options for invasive fungal infections (IFIs). Relative to amphotericin B deoxycholate, lipid-based formulations of amphotericin B have significantly reduced the incidence of nephrotoxicity, but at a significant increase in drug acquisition cost. Newer, broad-spectrum triazoles (notably voriconazole and posaconazole) have added significantly to both the prevention and treatment of IFIs, most notably Aspergillus spp. (with voriconazole) and the treatment of some emerging fungal pathogens. Finally, a new class of parenteral antifungals, the echinocandins, is employed most frequently against invasive candidal infections. While the role of these newer agents continues to evolve, this review summarizes the activity, safety and clinical applications of agents most commonly employed in the treatment of IFIs.

Abstract
BACKGROUND Cerebrospinal fluid (CSF) analysis is often deferred in patients with cryptococcal disease, particularly in the absence of neurologic manifestations. We sought to determine whether a subset of solid organ transplant (SOT) recipients with high likelihood of central nervous system (CNS) disease could be identified in whom CSF analysis must be performed. METHODS Patients comprised a multicenter cohort of SOT recipients with cryptococcosis. RESULTS Of 129 (88%) of 146 SOT recipients with cryptococcosis who underwent CSF analysis, 80 (62%) had CNS disease. In the overall study population, abnormal mental status, time to onset of cryptococcosis more than 24 months posttransplantation (late-onset disease), serum cryptococcal antigen titer more than 1:64, and fungemia were independently associated with an increased risk of CNS disease. Of patients with abnormal mental status, 95% had CNS cryptococcosis. When only patients with normal mental status were considered, three predictors (serum antigen titer >1:64, fungemia, and late-onset disease) independently identified patients with CNS cryptococcosis; the risk of CNS disease was 14% if none, 39% if one, and 94% if two of the aforementioned predictors existed (chi for trend P<0.001). CONCLUSIONS CSF analysis should be strongly considered in SOT recipients with cryptococcosis who have late-onset disease, fungemia, or serum cryptococcal antigen titer more than 1:64 even in the presence of normal mental status.

Abstract
Cryptococcosis is a global invasive mycosis associated with significant morbidity and mortality. These guidelines for its management have been built on the previous Infectious Diseases Society of America guidelines from 2000 and include new sections. There is a discussion of the management of cryptococcal meningoencephalitis in 3 risk groups: (1) human immunodeficiency virus (HIV)-infected individuals, (2) organ transplant recipients, and (3) non-HIV-infected and nontransplant hosts. There are specific recommendations for other unique risk populations, such as children, pregnant women, persons in resource-limited environments, and those with Cryptococcus gattii infection. Recommendations for management also include other sites of infection, including strategies for pulmonary cryptococcosis. 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. Three key management principles have been articulated: (1) induction therapy for meningoencephalitis using fungicidal regimens, such as a polyene and flucytosine, followed by suppressive regimens using fluconazole; (2) importance of early recognition and treatment of increased intracranial pressure and/or IRIS; and (3) the use of lipid formulations of amphotericin B regimens in patients with renal impairment. Cryptococcosis remains a challenging management issue, with little new drug development or recent definitive studies. However, if the diagnosis is made early, if clinicians adhere to the basic principles of these guidelines, and if the underlying disease is controlled, then cryptococcosis can be managed successfully in the vast majority of patients.

Abstract
OBJECTIVE To investigate the histopathology of the arachnoid granulations in patients with HIV-associated cryptococcal meningitis and correlate the findings with clinical data, in particular cerebrospinal fluid (CSF) opening pressure. DESIGN Case series. METHODS Postmortems were requested on patients dying during initial hospitalization with HIV-associated cryptococcal meningitis. RESULTS Five postmortems were performed. Large numbers of cryptococcal cells were seen within the arachnoid granulations. The number of fungal cells correlated with CSF pressure. Inflammatory cell infiltrates and disruption of the normal architecture of the granulations were also observed. CONCLUSION The study provides the first direct evidence supporting the obstruction to CSF reabsorption at the level of the arachnoid granulations as the main mechanism underlying the development of raised CSF pressure in HIV-associated cryptococcal meningitis.

Abstract
Cryptococcus neoformans is an opportunistic fungal pathogen that causes central nervous system and pulmonary disease among immunocompromised patients. Recent studies highlight the high incidence of cryptococcosis among patients in certain resource-poor areas, where there is also a high incidence of AIDS. Despite the availability of antifungal agents with anticryptococcal activity, the mortality and treatment-failure rates associated with cryptococcosis remain unacceptably high. This article reviews current treatment strategies and the basis for these strategies, as well as prospects for future approaches to the treatment of cryptococcosis.

Abstract
Cryptococcosis continues to have a high mortality rate in human immunodeficiency virus (HIV)-positive patients despite advances made in antifungal treatment, intracranial pressure management, and antiretroviral therapy. This retrospective chart review was conducted at the University of Maryland Medical Center and Baltimore VA Medical Center from 1993 to 2004. We reviewed all inpatient cases of cryptococcal infections to assess predictors of inpatient mortality among HIV-positive patients. Data collected included patient demographics, presenting symptoms and CD4 counts, lumbar puncture (LP) results including opening pressure (OP), cryptococcal antigen (CAg) levels, sites of infection, and drug therapy. Multivariate and survival analyses were performed. We identified 202 patients with primary cryptococcosis. The main sites of infection included blood (72%), central nervous system (85%), and lower respiratory tract (34%). Overall 30-day mortality was 14%. Predictors of mortality included syncope (P = 0.039; OR, 4.5), concomitant pneumonia (P = 0.001; OR, 3.5), respiratory failure (P < 0.001; OR, 10.5), and admission into the intensive care unit (P < 0.001; OR, 8). Amphotericin dose, OP > or = 250 mm H2O, and number of LPs were not found to be predictive of mortality. Mortality attributable to cryptococcosis remains high. Our study findings suggest that syncope, respiratory failure, pneumonia, and admission to the intensive care unit are independently associated with an increased risk of death within 30 days after cryptococcosis diagnosis.

Abstract
OBJECTIVES To assess impact of serial lumbar punctures on association between cerebrospinal fluid (CSF) opening pressure and prognosis in HIV-associated cryptococcal meningitis; to explore time course and relationship of opening pressure with neurological findings, CSF fungal burden, immune response, and CD4 cell count. DESIGN Evaluation of 163 HIV-positive ART-naive patients enrolled in three trials of amphotericin B-based therapy for cryptococcal meningitis in Thailand and South Africa. METHODS Study protocols required four lumbar punctures with measurements of opening pressure over the first 2 weeks of treatment and additional lumbar punctures if opening pressure raised. Fungal burden and clearance, CSF immune parameters, CD4 cell count, neurological symptoms and signs, and outcome at 2 and 10 weeks were compared between groups categorized by opening pressure at cryptococcal meningitis diagnosis. RESULTS Patients with higher baseline fungal burden had higher baseline opening pressure. High fungal burden appeared necessary but not sufficient for development of high pressure. Baseline opening pressure was not associated with CD4 cell count, CSF pro-inflammatory cytokines, or altered mental status. Day 14 opening pressure was associated with day 14 fungal burden. Overall mortality was 12% (20/162) at 2 weeks and 26% (42/160) at 10 weeks, with no significant differences between opening pressure groups. CONCLUSION Studies are needed to define factors, in addition to fungal burden, associated with raised opening pressure. Aggressive management of raised opening pressure through repeated CSF drainage appeared to prevent any adverse impact of raised opening pressure on outcome in patients with cryptococcal meningitis. The results support increasing access to manometers in resource-poor settings and routine management of opening pressure in patients with cryptococcal meningitis.

Abstract
The significance of cryptococcal infection as a cause of human disease has dramatically evolved in recent years. The objective of this study was to outline the worldwide significance of cryptococcosis and review developments in the management of cryptococcal meningitis. Cryptococcus neoformans var. grubii remains an important cause of disease, particularly in hosts with acquired immunosuppression. Cryptococcus gattii, on the other hand, infects hosts with seemingly normal immune systems and a recent dramatic outbreak in a new ecologic environment highlights the emerging clinical significance of this fungal pathogen. The introduction of new antifungal agents and the adoption of strategies for controlling elevated intracranial pressure in cryptococcal meningitis have added to our therapeutic options. However, the mortality from this infection remains unacceptably high and we are faced with the specific challenges in the management of this disease.

Abstract
BACKGROUND Cryptococcosis is a life-threatening opportunistic fungal infection in both HIV-positive and -negative patients. Information on clinical presentation and therapeutic guidelines, derived mostly from clinical trials performed before introduction of highly active antiretroviral therapy in patients with cryptococcal meningoencephalitis, is missing data on extrameningeal involvement and infections by serotype D as opposed to serotype A of Cryptococcus neoformans. METHODS AND FINDINGS The prospective multicenter study CryptoA/D was designed in France (1997-2001) to analyse the factors influencing clinical presentation and outcome without the bias of inclusion into therapeutic trials. Of the 230 patients enrolled, 177 (77%) were HIV-positive, 50 (22%) were female, and 161 (72.5%) were infected with serotype A. Based on culture results at baseline, cryptococcosis was more severe in men, in HIV-positive patients, and in patients infected with serotype A. Factors independently associated with mycological failure at week 2 independent of HIV status were initial dissemination (OR, 2.4 [95% confidence interval (CI), 1.2-4.9]), high (>1:512) serum antigen titre (OR, 2.6 [1.3-5.4]), and lack of flucytosine during induction therapy (OR, 3.8 [1.9-7.8]). The three-month survival was shorter in patients with abnormal neurology or brain imaging at baseline, and in those with haematological malignancy. CONCLUSIONS Thus sex, HIV status, and infecting serotype are major determinants of presentation and outcome during cryptococcosis. We propose a modification of current guidelines for the initial management of cryptococcosis based on systematic fungal burden evaluation.

Abstract
In the past 2 decades, Cryptococcus has emerged in its clinical significance and as a model yeast for understanding molecular pathogenesis. C neoformans and C gattii are currently considered major primary and secondary pathogens in a wide array of hosts that are known to be immunocompromised or apparently immunocompetent. A recent outbreak of C gattii infections further underscores the clinical importance of the yeast through its epidemiology and pathogenicity features. With an enlarging immunosuppressed population caused by HIV infection, solid organ transplantation, and clinical use of potent immunosuppressives, such as cancer chemotherapy, monoclonal antibodies, and corticosteroids, this fungus has become a well-established infectious complication of modern medicine. This article examines current issues in cryptococcal infections, including new classification, epidemiology, pathogenesis, and specific clinical aspects.

Abstract
PURPOSE OF REVIEW Combined antifungal drug therapy is widely used in severe invasive mycoses in solid organ transplant (SOT) recipients. We have reviewed the available data in the literature. RECENT FINDINGS No single randomized study on antifungal combination therapy in SOT patients has been performed. Existing information does not support the use of combination therapy in invasive candidiasis in SOT patients. Indeed, initial combination therapy with amphotericin B and 5-flucytosine is recommended for SOT patients with central nervous system cryptococcosis, mainly with increased white blood cell counts in the cerebrospinal fluid or with altered mental status. No impact on outcome was observed with combination therapy in Scedosporium infections in SOT patients. The combination of voriconazole and terbinafine may be an attractive option for S. prolificans infections. A prospective study of voriconazole plus caspofungin as initial therapy for invasive aspergillosis in SOT patients found that combination therapy was independently associated with reduced mortality in patients with renal failure and in those with Aspergillus fumigatus infection, even when adjusted for other factors predictive of mortality in the study population. SUMMARY Combination therapy should be considered for severe forms of invasive fungal infections in SOT patients; however, multicenter studies of such patients are urgently needed.
