Abstract
BACKGROUND Disseminated cryptococcosis is a rare disease in children, especially in children with normal immunity. The understanding of this disease needs to be improved. This study aims to update the global situation of disseminated cryptococcosis in non-HIV infected children for the first time. METHODS The clinical data of a child with disseminated cryptococcosis was retrospectively analyzed, and disseminated cryptococcosis clinical features of published studies were summarized. Electronic databases were searched in February 2025. Clinical studies that meet the criteria were included in the present study. RESULTS Totally 116 cases were analyzed in this study, including 1 case in our center and 115 cases from 45 studies. The cohort included 82 males (70.7%) and 34 females (29.3%), with ages ranging from 10 months to 18 years. The main clinical manifestations were fever (79.3%), respiratory symptoms (41.4%), and neurological symptoms (39.7%), followed by hepatosplenomegaly (35.3%), rash (27.6%), lymphadenopathy (18.1%), and gastrointestinal symptoms (16.4%). The most commonly affected organs were the lungs (77.6%), central nervous system (53.4%), and lymph nodes (51.7%). Immunodeficiency was present in 12.9% of children (3.4% domestic cases vs. 9.5% foreign cases). Elevated eosinophils were observed in 43 patients (37.1%), and elevated IgE levels in 35 patients (30.2%). The most common pathogen-positive specimens were cerebrospinal fluid (54 cases, 46.6%), blood cultures (49 cases, 42.2%), lymph node biopsies (26 cases, 22.4%), bone marrow (18 cases, 15.5%), and skin samples (8 cases, 6.9%). Combination therapy was administered to 89 patients (76.7%), while 21 patients (18.1%) received monotherapy. Clinical improvement occurred in 94 patients (81.0%), with 15 fatal cases. CONCLUSIONS Disseminated cryptococcosis in children often presents with fever, respiratory and neurological symptoms, with the lungs, central nervous system, and lymph nodes being the most frequently involved organs. Most cases do not have immunodeficiency or underlying diseases, and blood tests often reveal eosinophilia and elevated IgE levels. The positive detection rates of pathogens are relatively high in blood cultures, cerebrospinal fluid, bone marrow cultures, and lymph node biopsies. The majority of patients achieved favorable therapeutic outcomes with combination therapy.

Abstract
Cryptococcosis is a fungal disease with worldwide distribution and wide array of clinical manifestations, caused by encapsulated basidiomycetous yeasts called Cryptococcus spp. It has traditionally been considered an opportunistic infection known to occur in immunocompromised hosts, particularly those who are infected with human immunodeficiency virus. However, this infection has also been reported in phenotypically 'normal' or otherwise clinically non-immunocompromised patients. The seemingly mysterious nature of this potentially fatal illness has always kept clinicians and diagnosticians in a dilemma. This case series reiterates this perspective.

Genotypic diversity and antifungal susceptibility of Cryptococcus neoformans isolates from paediatric patients in China. Mycoses 2018; 62:171-180. [PMID: 30341799 DOI: 10.1111/myc.12863] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2018] [Revised: 09/20/2018] [Accepted: 10/14/2018] [Indexed: 12/11/2022]
Abstract
Cryptococcosis is a life-threatening mycosis primarily occurring in adult patients particularly those with immunosuppression such as HIV infection/AIDS. The number of reported cases of paediatric cryptococcosis has increased in the last decade around the world, including China. However, current information on the characteristics of cryptococcosis in children, particularly the genotypic diversity and antifungal susceptibility of the isolates, is limited. In the present study, a total of 25 paediatric isolates of Cryptococcus neoformans were genotyped using the ISHAM-MLST scheme. In vitro susceptibility to antifungal agents of the 22 isolates was tested using the CLSI M27-A3 method. Our analyses revealed that the genotypic diversity of C. neoformans isolates from Chinese paediatric patients was low, with ST 5 (80%) and ST 31 (12%) being the two major sequence types. Reduced susceptibility to fluconazole (FLU), 5-flucytosine (5-FC) and itraconazole (ITR) was observed among C. neoformans isolates from Chinese paediatric patients, particularly among the ST5 isolates, which was similar to observations made on C. neoformans isolates from Chinese adult patients. In addition, the majority of isolates (3/4, 75%) obtained from deceased patients showed decreased antifungal susceptibility, which indicates that further monitoring of antifungal susceptibility of Cryptococcus isolates is warranted in management of paediatric cryptococcosis.
