Abstract
BACKGROUND Seroprevalence studies have shown that 70% of children are exposed to Cryptococcus , the most common cause of meningitis in people living with human immunodeficiency virus (HIV), but reported pediatric disease prevalence is much lower than in adults. METHODS PubMed and Ovid Global Health databases were searched with the terms "cryptococcosis," "cryptococcal meningitis," " Cryptococcus neoformans " or " Cryptococcus gattii ." All studies reporting pediatric specific data in the English language from 1980 up until December 2022 were included. RESULTS One hundred sixty-eight publications were reviewed totaling 1469 children, with the majority reported from Africa (54.2%). Sixty-five percent (961) were HIV positive, 10% (147) were non-HIV immunocompromised and 19% (281) were immunocompetent. Clinical signs and symptoms were only reported for 458 children, with fever (64%), headache (55%) and vomiting (39%) being the most common. Most children (80%) suffered from meningoencephalitis. Lung involvement was rarely described in HIV-positive children (1%), but significantly more common in the non-HIV immunocompromised (36%) and immunocompetent (40%) groups ( P < 0.0001). Only 22% received the recommended antifungal combination therapy, which was significantly higher in immunocompetent children than those with HIV (39% vs. 6.8%; P < 0.0001). Overall mortality was 23%. A significant higher mortality was observed in children with HIV compared with immunocompetent children (32% vs. 16%; P < 0.001), but not compared with children with non-HIV immunosuppression (25). CONCLUSIONS This is the largest review of pediatric cryptococcosis with new observations on differences in clinical presentation and outcome depending on the underlying condition. The lack of granular clinical data urges prospective clinical epidemiological studies for improved insight in the epidemiology, management and outcome of cryptococcosis in children.

Abstract
OBJECTIVES Describe the epidemiology of immunocompromised HIV-infected pediatric (children and adolescents ≤ 19 years) and adults (> 19 years) with positive serum cryptococcal antigen lateral flow assay (CrAg-LFA) in KwaZulu-Natal. DESIGN Retrospective review of laboratory-based database and clinical charts. METHODS A review of the National Health Laboratory Services database of all serum CrAg-LFA performed in KwaZulu-Natal between June 2015 and December 2016 and comparison of the epidemiology of pediatric and adult patients was conducted. A reflex serum CrAg-LFA (IMMY CrAg-LFA) was performed on samples with CD4 counts < 100 cells/μL. Charts of all pediatric patients with a positive CrAg-LFA at Prince Mshiyeni Memorial Hospital were reviewed and 1-year outcome assessed. RESULTS A total of 22,741 laboratory records were retrieved, and 1140 records were removed because of duplicate entries (1074) and insufficient data (64). There was a statistically significant difference in the incidence of positive CrAg-LFA in pediatrics and adults, respectively [40 (3.5%) versus 1194 (5.8%), P = 0.001]. The incidence of positive CrAg-LFA in Ethekwini district was 59 and 56 cases per 100,000 persons in adolescents 10-14 years and 15-19 years, respectively. Six of the 8 patients with available treatment history were on antiretroviral treatment (ART) with immune failure at the time of CrAg-LFA testing. CONCLUSIONS Severe immune suppression in adolescents on ART is a risk factor for cryptococcal antigenemia. A concerted effort to timeously manage ART failure in adolescents with appropriate changing of ART regimens is urgently warranted.

Abstract
Aim: Cryptococcosis causes significant morbidity and mortality worldwide, but pediatric data are limited. Methods: A retrospective literature review of Australian pediatric cryptococcosis and additional 10-year audit of cases from a large pediatric network. Results: 22 cases of cryptococcosis in children were identified via literature review: median age was 13.5 years (IQR 7.8-16 years), 18/22 (82%) had meningitis or central nervous system infection. Where outcome was reported, 11/18 (61%) died. Of six audit cases identified from 2008 to 2017, 5 (83%) had C. gattii disease and survived. One child with acute lymphoblastic leukemia and C. neoformans infection died. For survivors, persisting respiratory or neurological sequelae were reported in 4/6 cases (67%). Conclusion: Cryptococcosis is uncommon in Australian children, but is associated with substantial morbidity.

Abstract
Invasive fungal diseases (IFDs) are devastating opportunistic infections that result in significant morbidity and death in a broad range of pediatric patients, particularly those with a compromised immune system. Recognizing them can be difficult, because nonspecific clinical signs and symptoms or isolated fever are frequently the only presenting features. Therefore, a high index of clinical suspicion is necessary in patients at increased risk of IFD, which requires knowledge of the pediatric patient population at risk, additional predisposing factors within this population, and the clinical signs and symptoms of IFD. With this review, we aim to summarize current knowledge regarding the recognition and clinical presentation of IFD in neonates and children.

Abstract
Although uncommon in children, fungal infections of the central nervous system can be devastating and difficult to treat. A better understanding of basic mycologic, immunologic, and pharmacologic processes has led to important advances in the diagnosis and management of these diseases, but their mortality rates remain unacceptably high. In this focused review, we examine the epidemiology and clinical features of the most common fungal pathogens of the central nervous system in children and explore recent advances in diagnosis and antifungal therapy.

Abstract
Background Data regarding HIV-seronegative pediatric patients with cryptococcal meningitis (CM) have been very limited. Methods We retrospectively reviewed non-HIV-infected in patients with CM from January 2002 through December 2013 in Beijing Children’s Hospital. Records of the all patients were obtained and compared. Results The 34 children had a median age of 5.6 years. Most of the patients were male (67.6 %). Only 23.5 % of the cases had identifiable underlying diseases. The sensitivity of the CSF cryptococcal antigen, India ink smear and CSF culture in our study were 81.5, 85.3 and 82.4 %, respectively. And the sensitivity of combinations of these tests was 91.2 %. Out of the 34 patients, 16 (47.1 %) had other organs involvement in addition to the brain. The main abnormal features via magnetic resonance imaging (MRI) were Virchow-Robin space dilatation (44.4 %), hydrocephalus (38.9 %), gelatinous pseudocysts (33.3 %), brain atrophy (33.3 %), meningeal enhancement (27.8 %) and local lesions (27.8 %). In total, 64.7 % of the patients were successfully treated at discharge, whereas treatment failed in 35.3 % of the patients. Conclusions Cryptococcal meningitis is an infrequent disease with a high fatality rate in children in China. The majority of patients were apparently healthy. Clinicians should consider cryptococcal infection as a potential pathogen of pediatric meningitis. Cryptococcal antigen, India ink smear and culture tests are recommended for diagnosis.

Abstract
Cryptococcus neoformans is an encapsulated fungal pathogen that is remarkable for its tendency to cause meningoencephalitis, especially in patients with AIDS. While disease is less common in children than adults, it remains an important cause of morbidity and mortality among HIV-infected children without access to anti-retroviral therapy. This review highlights recent insights into both the biology and treatment of cryptococcosis with a special emphasis on the pediatric literature.

Abstract
Cryptococcal meningitis is uncommon in children, particularly in infants. A 2-day-old boy was admitted with signs suggestive of meningitis. Lumbar puncture confirmed meningitis and cryptococcal infection (cryptococcal antigen and Indian ink stain-positive). His mother was HIV-negative. This is thought to be the youngest case of cryptococcal meningitis to be reported. Cryptococcal infection should be considered in children of all ages with meningitis where there is possible immunodeficiency or failure to respond to initial treatment with antibiotics.

Abstract
Cryptococcosis is reported in adults and is often acquired immune deficiency syndrome (AIDS)-associated; however, its frequency in children is low. Based on the National Survey on Cryptococcosis conducted in Colombia, an epidemiological and clinical analysis was performed on cases of the disease observed in children less than 16 years old between 1993-2010. We found 41 affected children (2.6% prevalence) from the 1,578 surveys received. The country mean annual incidence rate was 0.017 cases/100,000 children under 16 years, while in Norte de Santander the incidence rate was 0.122 cases/100,000 (p < 0.0001). The average age of infected children was 8.4 and 58.5% were male. In 46.3% of cases, a risk factor was not identified, while 24.4% had AIDS. The most frequent clinical manifestations were headache (78.1%), fever (68.8%), nausea and vomiting (65.6%), confusion (50%) and meningeal signs (37.5%). Meningitis was the most frequent clinical presentation (87.8%). Amphotericin B was given to 93.5% of patients as an initial treatment. Positive microbiological identification was accomplished by India ink (94.7%), latex in cerebrospinal fluid (100%) and culture (89.5%). Out of 34 isolates studied, Cryptococcus neoformans var. grubii (VNI 85.3%, VNII 8.8%) was isolated in 94.1% of cases and Cryptococcus gattii (VGII) was isolated in 5.9% of cases. These data are complemented by a literature review, which overall suggests that cryptococcosis in children is an unusual event worldwide.

Abstract
Cryptococcal meningitis is a life-threatening opportunistic fungal infection in both HIV-infected and HIV-uninfected patients. According to the most recent taxonomy, the responsible fungus is classified into a complex that contains two species (Cryptococcus neoformans and C. gattii), with eight major molecular types. HIV infection is recognized worldwide as the main underlying disease responsible for the development of cryptococcal meningitis (accounting for 80-90% of cases). In several areas of sub-Saharan Africa with the highest HIV prevalence despite the recent expansion of antiretroviral (ARV) therapy programme, cryptococcal meningitis is the leading cause of community-acquired meningitis with a high mortality burden. Although cryptococcal meningitis should be considered a neglected disease, a large body of knowledge has been developed by several studies performed in recent years. This paper will focus especially on new clinical aspects such as immune reconstitution inflammatory syndrome, advances on management, and strategies for the prevention of clinical disease.

Abstract
BACKGROUND Although cryptococcal meningitis (CM) is an emerging disease worldwide, there have been few studies of the characteristics and risk factors of CM in children. METHODS We used data collected from May 2007 through April 2012 in the Acute Meningitis-Encephalitis Syndrome Surveillance project in Shi Jiazhuang, China to describe the epidemiologic, clinical, and laboratory findings in children with CM. Furthermore, a matched case-control study was used to determine risk factors of CM. RESULTS Overall 23 HIV-negative children with CM (median age: 10.91 years; range: 5 months-17 years) were enrolled in our study. The average annual incidence of CM was 0.43/100,000 with a fatality rate of 1.7%. Most patients were males (60.87%) and rural children (73.91%). Common clinical symptoms included increased intracranial pressure, such as headaches (78.3%), nausea (60.9%), altered mental status (56.5%), vomiting (52.2%), and seizures (43.5%), and frequent laboratory findings consisted of blood leukocytosis (87.0%), decreased CSF glucose (87.0%), pleocytosis (82.6%), increased intracranial pressure (73.9%) and elevated CSF proteins (65.2%). Epidemiologic, clinical, and laboratory findings were similar between patients with and without underlying diseases. Multivariate logistic regression analysis showed that children who had contact with birds/bird droppings or saprophytes were more likely to be infected than those without such contact (odds ratio(OR) =11.82; 95% confidence interval (CI), 2.21-62.24; P = 0.004). Patients with an interval of ≥20 days from onset to admission were at high risk for CM (OR= 5.31; 95%CI, 1.58-17.89; P = 0.007). CONCLUSIONS Our findings show that CM is an uncommon disease with a high mortality rate in children. Although additional studies are needed to find effective prevention and treatments for CM, clinicians should consider CM as a potential cause for pediatric meningitis in children, particularly boys from rural areas, who had contact with birds/bird droppings or saprophytes and in children who did not receive prompt medical attention.

Abstract
Objectives To determine the incidence of WHO clinical stage 3 and 4 conditions during early anti-retroviral therapy (ART) in resource limited settings (RLS). Design/Setting A descriptive analysis of routine program data collected prospectively from 25 Médecins Sans Frontières supported HIV treatment programs in eight countries between 2002 and 2010. Subjects/Participants 35,349 study participants with median follow-up on ART of 1.33 years (IQR 0.51–2.41). Outcome Measures Incidence in 100 person-years of WHO stage 3 or 4 conditions during 5 periods after ART initiation. Diagnoses of conditions were made according to WHO criteria and relied upon clinical assessments supported by basic laboratory investigations. Results The incidence of any WHO clinical stage 3 or 4 condition over 3 years was 40.02 per 100 person-years (31.77 for stage 3 and 8.25 for stage 4). The incidence of stage 3 and 4 conditions fell by over 97% between months 0–3 and months 25–36 (77.81 to 2.40 for stage 3 and 28.70 to 0.64 for stage 4). During months 0–3 pulmonary tuberculosis was the most common condition diagnosed in adults (incidence 22.24 per 100 person-years) and children aged 5–14 years (25.76) and oral candidiasis was the most common in children <5 years (25.79). Overall incidences were higher in Africa compared with Asia (43.98 versus 12.97 for stage 3 and 8.98 versus 7.05 for stage 4 conditions, p<0.001). Pulmonary tuberculosis, weight loss, oral and oesophageal candidiasis, chronic diarrhoea, HIV wasting syndrome and severe bacterial infections were more common in Africa. Extra-pulmonary tuberculosis, non-tuberculous mycobacterial infection, cryptococcosis, penicilliosis and toxoplasmosis were more common in Asia. Conclusions The incidence of WHO stage 3 and 4 conditions during the early period after ART initiation in RLS is high, but greatly reduces over time. This is likely due to both the benefits of ART and deaths of the sickest patients occurring shortly after ART initiation. Access to appropriate disease prevention tools prior to ART, and early initiation of ART, are important for their prevention.

Abstract
In low-income countries, children ≥4 years and adults with low CD4 count have equally high mortality risk in the 3 months after initiation of antiretroviral therapy, similar to that of untreated individuals. Bacterial infections play a major role; targeted interventions could have important benefits. Background. Adult mortality in the first 3 months on antiretroviral therapy (ART) is higher in low-income than in high-income countries, with more similar mortality after 6 months. However, the specific patterns of changing risk and causes of death have rarely been investigated in adults, nor compared with children in low-income countries. Methods. We used flexible parametric hazard models to investigate how mortality risks varied over the first year on ART in human immunodeficiency virus–infected adults (aged 18–73 years) and children (aged 4 months to 15 years) in 2 trials in Zimbabwe and Uganda. Results. One hundred seventy-nine of 3316 (5.4%) adults and 39 of 1199 (3.3%) children died; half of adult/pediatric deaths occurred in the first 3 months. Mortality variation over year 1 was similar; at all CD4 counts/CD4%, mortality risk was greatest between days 30 and 50, declined rapidly to day 180, then declined more slowly. One-year mortality after initiating ART with 0–49, 50–99 or ≥100 CD4 cells/μL was 9.4%, 4.5%, and 2.9%, respectively, in adults, and 10.1%, 4.4%, and 1.3%, respectively, in children aged 4–15 years. Mortality in children aged 4 months to 3 years initiating ART in equivalent CD4% strata was also similar (0%–4%: 9.1%; 5%–9%: 4.5%; ≥10%: 2.8%). Only 10 of 179 (6%) adult deaths and 1 of 39 (3%) child deaths were probably medication-related. The most common cause of death was septicemia/meningitis in adults (20%, median 76 days) and children (36%, median 79 days); pneumonia also commonly caused child deaths (28%, median 41 days). Conclusions. Children ≥4 years and adults with low CD4 values have remarkably similar, and high, mortality risks in the first 3 months after ART initiation in low-income countries, similar to cohorts of untreated individuals. Bacterial infections are a major cause of death in both adults and children; targeted interventions could have important benefits.

Abstract
To describe clinical characteristics, treatment and outcome of cryptococcal meningitis in immunocompetent children. Immunocompetent children with cryptococcal meningitis who attended Changzheng Hospital between 1998 and 2007 were retrospectively reviewed. During the 10 years reviewed, 11 children with cryptococcal meningitis were admitted to Changzheng hospital and identified as immunocompetent. The 11 children had a median age of 7.25 years. Headache (100%), fever (81.8%), nausea or vomiting (63.6%) and visual or hearing damage or loss (36.4%) were the most common symptoms before treatment. There is no evidence for other site infection of cryptococcus although all the cryptococcal antigen titre is high in blood. All the patients received amphotericin B or AmB liposome with 5-flucytosine for at least 6 weeks followed by fluconazole or itraconazole as consolidation treatment for at least 12 weeks. Nine patients were cured mycologically; however, sequela of visual damage was showed in one patient. Cryptococcal meningitis seems to be uncharacteristic of symptoms, and central nervous system may be the only common site for infection. Amphotericin B with 5-flucytosine should be the choice of induction treatment in this group of patients.

Abstract
BACKGROUND Cryptococcus neoformans is a common opportunistic infection in adults with acquired immunodeficiency syndrome (AIDS), but cryptococcal infection (CI) has also been recognized in HIV-negative patients. Despite the fact that many studies were conducted in adults, limited data exist for pediatric patients. METHODS The Pediatric Health Information System, a database containing administrative information from 42 United States children's hospitals, was used to identify children admitted for the treatment of CI between 2003 and 2008. All pediatric inpatients less than 19 years of age who received an ICD-9 code for cryptococcosis or cryptococcal meningitis (CM) were included. Data regarding presence of underlying medical conditions, antifungal therapies administered, and hospital discharge disposition were evaluated. RESULTS A total of 63 cases of CI were identified, for a CI admission frequency of 6.2 cases per million hospitalizations. Most patients (63.5%) had an underlying immunocompromising medical condition, whereas 21% were immunocompetent and 16% were infected with HIV. Cryptococcosis not involving the central nervous system was more common than CM (62% vs. 38%). Most patients received a combination of fluconazole, amphotericin, and flucytosine in their treatment regimen; however, 9 patients received no antifungal medications. The overall in-hospital case fatality rate was 9.5%. CONCLUSIONS The majority of pediatric cryptococcosis occurred in non-HIV-infected patients. However, most patients had other immunocompromising medical conditions. Patients with CM usually received therapy in accordance with the Infectious Disease Society of America guidelines for adults, but patients with non-CM were more likely to receive therapies not supported by these guidelines.

Abstract
Pediatric cryptococcosis has been documented in various organs, but pediatric renal cryptococcosis (RC) remains undocumented to date. The authors report RC in 2 children with AIDS, 7 and 9 years of age, with proteinuria. Both patients, on antiretroviral therapy (ARV) for 28 (patient 1) and 54 (patient 2) weeks each, had secured viral immunosuppression, but immune restoration was realized by patient 1 only. Cryptococcal immune reconstitution inflammatory syndrome (IRIS) was diagnosed on the renal biopsy from patient 1 based on the clinicopathological profile and the presence of segmental glomerular and an interstitial lymphoplasmacytic and granulomatous reaction to Cryptococcus neoformans, with a predominance of capsule-deficient fungal forms. The renal biopsy from patient 2 demonstrated typical HIV-associated nephropathy with focal intratubular and interstitial C neoformans yeasts. Pediatric AIDS-associated renal disease must be expanded to include RC and cryptococcal IRIS, and the kidney must be included as a potential sentinel site of IRIS.

Abstract
Between 1991-2006, nine patients below age 18 years, with a microbiologic documentation of Cryptococcus neoformans infection and no evidence of human immunodeficiency virus infection, were identified and treated at Chang Gung Children's Hospital. All exhibited central nervous system involvement. Seven patients were female (age range, 9-16 years; mean age, 13.7 years). Five patients (56%) manifested underlying diseases and were receiving either steroid or immunosuppressant treatment at time of disease onset. Eight patients presented with meningitis. Headache, vomiting, and focal neurologic signs were the most common presentations. Protein and sugar levels in cerebrospinal fluid were within normal range in seven cases, whereas India ink smear and cryptococcal antigen testing were positive in 87% (7/8) and 78% (7/9) of patients, respectively. With prompt antifungal therapy, all survived, but one presented the sequel of blindness. Cryptococcosis is uncommon in the nonhuman immunodeficiency virus-infected pediatric population. Clinicians should take into account a diagnosis of central nervous system cryptococcosis when children present with prolonged headache, vomiting, and focal neurologic signs. Indian ink stain and cryptococcal antigen testing of cerebrospinal fluid should be performed.

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
Cryptococcosis is a systemic-opportunistic mycosis caused by two species of the encapsulated yeast-like organism, Cryptococcus neoformans and C. gattii, which cause infection in immunocompromised individuals and in immunologically normal hosts, respectively. Most susceptible to infection are patients with T-cell deficiencies. The spectrum of disease ranges from asymptomatic pulmonary lesions to disseminated infection with meningoencephalitis. After the emergence of AIDS, cryptococcal infections have become much more common. The mycosis occurs less frequently in children than in adults. The purpose of this article is to discuss the aetiology, clinical presentation, predisposing conditions and outcomes in cases of cryptococcosis in children. Emphasis is placed upon paediatric cases occuring in Brazil and in particular to highlight the difference between cases diagnosed in Porto Alegre (South - subtropical climate) and in Belem (North - equatorial climate).

Abstract
Disseminated cryptococcal disease is often associated with immunodeficient states. The diagnosis is usually made using standard antigen tests on serum and cerebrospinal fluid in patients with known immunodeficiency. Often, blood and cerebrospinal fluid cultures also yield Cryptococcus neoformans. The authors describe a child whose diagnosis remained elusive until a bone marrow aspiration, performed as part of an evaluation for suspected neoplasm, revealed the offending organism.

Abstract
Cryptococcal meningitis was diagnosed in a 92-day-old boy who was not HIV-1-infected and who survived after treatment, although with hydrocephalus. The mother was HIV-1-infected, delivered prematurely, had peripartum cryptococcal meningitis and died 14 days postpartum. There was no other possible source for cryptococcal infection in this infant. This is believed to be a case of mother-to-child transmission of cryptococcosis.

Abstract
Pulmonary cryptococcosis is an uncommonly recognized disease of childhood. Among immunocompetent and non-HIV-infected individuals, pulmonary cryptococcosis may be asymptomatic or present with chronic, nondescript symptomatology. In this report we describe a 10-year-old with malignant fibrous histiocytoma of bone and a pulmonary nodule secondary to Cryptococcus neoformans. We use this case as a background to review the pediatric literature regarding pulmonary cryptococcosis and to discuss the utility of immunohistochemistry for diagnosis of this clinical entity.

Abstract
Cryptococcal meningitis is an uncommon but often fatal complication of systemic lupus erythematosus (SLE). We report on a 13-year-old girl with SLE using high-dose prednisolone for several months, presented to us with low grade fever, intermittent vomiting and headache. Physical examination, including papilloedema and meningeal irritation, was unremarkable. Serum and cerebrospinal fluid (CSF) cryptococcal antigen titer was 1: 128 by latex agglutination method. CSF culture yielded Cryptococcus neoformans. We used amphotericin B deoxycholate (a cumulative dose of 1.95 gm) and fluconazole (200 mg day-1) for 6 weeks. Clinical response was good. Then, we continued fluconazole 200 mg per qd as suppressive therapy for thirty-four months. There were no neurological sequelae or relapse after 20-month follow-up. Timely diagnosis and effective antifungal therapy could improve the prognosis of cryptococcal meningitis in SLE patients.

Abstract
BACKGROUND The number of children with AIDS in Africa is high. Such children may be at risk for cryptococcal meningoencephalitis, but data are scarce regarding this disease in our population. METHODS We examined records of HIV-infected children (< or =16 years) diagnosed with cryptococcal meningoencephalitis in Harare, Zimbabwe, between 1995 and 2000. To elucidate features unique to pediatric disease, the children were compared with adult patients with HIV-associated cryptococcal meningoencephalitis. RESULTS Thirteen children presented to our institution with headache (85%), nuchal rigidity (69%), vomiting (46%), impaired mental status (38%), convulsions (38%) and focal neurologic signs (23%). The mean duration of symptoms before diagnosis was 9 days. Cerebrospinal fluid examination revealed normal white blood cell counts in 64%, protein value in 67% and glucose concentration in 57% of patients. Children were more likely than adults to have seizures (38% vs. 11%, P = 0.02) and normal cerebrospinal fluid protein (67% vs. 10%, P < 0.01). The in-hospital mortality was 43%. Convulsions (P = 0.05) and impaired mental status (P < 0.01) were associated with increased mortality CONCLUSIONS Cryptococcal meningoencephalitis in African children presents acutely or subacutely, can have a fulminant picture and is consistent with progressive meningoencephalitis.

Abstract
OBJECTIVE Cryptococcus neoformans is an important cause of central nervous system infection in adults with acquired immunodeficiency syndrome (AIDS) but an unusual cause of disease in children with AIDS. The basis for this age-related difference in incidence is not known but may be caused by differences in exposure or immune response. The objective of this study was to determine whether the low prevalence of cryptococcal disease among children is related to a lack of exposure to C neoformans. METHODS Sera were obtained from 185 immunocompetent individuals ranging in age from 1 week to 21 years who were being evaluated in an urban emergency department. Sera were analyzed for antibodies to C neoformans and Candida albicans proteins by immunoblotting. Immunoblot patterns were compared with those obtained from sera of patients with cryptococcosis (n = 10) and workers in a laboratory devoted to the study of C neoformans. The specificity of our results was confirmed by several approaches, including antibody absorption and blocking studies. Sera were also analyzed for the presence of cryptococcal polysaccharide by both enzyme-linked immunosorbent assay and latex agglutination assays. RESULTS Sera from children 1.1 to 2 years old demonstrated minimal reactivity to C neoformans proteins. In contrast, the majority of sera from children >2 years old recognized many (>/=6) C neoformans proteins. For children between 2.1 and 5 years old, 56% of sera (n = 25) reacted with many proteins, whereas for children >5 years old (n = 120), 70% of samples reacted with many proteins. Reactivity was decreased by absorbing sera with C neoformans extracts or by preincubating blots with sera from experimentally infected but not from control rats. Reactivity to C neoformans proteins did not correlate with reactivity to C albicans proteins, which was common in sera from children between the ages of 1.1 and 2 years. Cryptococcal polysaccharide was detected at a titer of 1:16 (~10 ng/mL) in the sera of 1 child, a 5.6-year-old boy who presented to the emergency department with vomiting. CONCLUSIONS Our findings provide both indirect and direct evidence of C neoformans infection in immunocompetent children. Our results indicate that C neoformans infects a majority of children living in the Bronx after 2 years old. These results are consistent with several observations: the ubiquitous nature of C neoformans in the environment, including its association with pigeon excreta; the large number of pigeons in urban areas; and the increased likelihood of environmental exposure for children once they have learned to walk. The signs and symptoms associated with C neoformans infection in immunocompetent children remained to be determined. Primary pulmonary cryptococcosis may be asymptomatic or produce symptoms confused with viral infections and, therefore, not recognized as a fungal infection. Our results suggest that the low incidence of symptomatic cryptococcal disease in children with AIDS is not a result of lack of exposure to C neoformans. These findings have important implications for C neoformans pathogenesis and the development of vaccine strategies.

Abstract
We report the case of a 22-month-old African boy with cutaneous lesions as the predominant feature of disseminated cryptococcosis (positive blood and cerebrospinal fluid cultures) and as the presenting manifestation of severe vertically acquired HIV infection (CDC C3 category). To our knowledge these cutaneous lesions have never been reported as the initial manifestation of AIDS in children.

Abstract
As the decade draws to a close, physicians can be cautiously optimistic about the prevention and treatment of opportunistic infections in children with HIV disease. As more children receive therapy with powerful antiretroviral regimens, fewer are likely to be at risk for opportunistic pathogens. The widespread use of protease inhibitor combination therapies has already resulted in a dramatic decrease in morbidity and mortality in the population of HIV-infected adults. The same effect has been seen at pediatric care centers throughout the United States. Clinicians caring for HIV-infected children are now considering the safety of discontinuing prophylactic therapies for children with sustained immunologic improvement on antiretroviral therapy. For children who remain at risk, prophylactic regimens for PCP and MAC have been shown to decrease the risk for these infections. Preventive regimens for several other opportunistic infections are also available. The understanding of the pathogenesis of HIV and many of the opportunistic pathogens has led to the development of a variety of efficacious therapies for these infections. Despite these advances, physicians can anticipate that HIV-infected children will continue to develop opportunistic infections and other related complications. Some children fail to respond to antiretroviral therapies, whereas others are unable to tolerate the complex medication regimens. Prophylactic therapies are not 100% protective and, despite improved treatments, few opportunistic infections are cured. Most require lifelong maintenance therapy in the absence of immune reconstitution. Drug interactions, complex dosing schedules, adverse side effects, and high costs further limit the efficacy of these therapies. The prophylaxis, diagnosis, and treatment of opportunistic infections are likely to remain integral components of HIV care for the near and distant future.

Abstract
BACKGROUND Lipid formulations of amphotericin B have been recently introduced for treatment of invasive fungal infections. However, little is known about their role in pediatric populations. METHODS We studied the safety and antifungal efficacy of amphotericin B lipid complex (ABLC, Abelcet) in 111 treatment episodes in pediatric patients through an open label, emergency use multicenter study. Patients with invasive fungal infections were enrolled if they had mycoses refractory to conventional antifungal therapy, if they were intolerant of previous systemic antifungal agents or concomitant nephrotoxic drugs or if they had preexisting renal disease. RESULTS All 111 treatment episodes were evaluable for safety and 54 were evaluable for efficacy. The mean serum creatinine for the study population did not significantly change between baseline (1.23 +/- 0.11 mg/dl) and cessation of ABLC therapy (1.32 +/- 0.12 mg/dl) during 6 weeks. There were no significant differences observed between initial and end-of-therapy levels of serum potassium, magnesium, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and hemoglobin. However, there was an increase in mean total bilirubin (3.66 +/- 0.73 to 5.31 +/- 1.09 mg/dl) at the end of therapy (P = 0.054). Among 54 cases fulfilling criteria for evaluation of antifungal efficacy, a complete or partial therapeutic response was obtained in 38 patients (70%) after ABLC therapy. Complete or partial therapeutic response was documented in 56% of cases with aspergillosis (n = 25) and in 81% (n = 27) with candidiasis. Among premature infants (n = 8) and allogeneic marrow recipients (n = 14), response rates were 88 and 57%, respectively. Response was similar in those patients enrolled because of intolerance to previous antifungal therapy or because of progressive infection. CONCLUSIONS These data support the use of ABLC for treatment of invasive fungal infections in pediatric patients who are intolerant of or refractory to conventional antifungal therapy.
