Knowledge about the clinical characteristics and prognostic factors of Talaromyces marneffei infection in children is limited, especially in HIV-positive children. We performed a retrospective study of all HIV-positive pediatric inpatients with T. marneffei infection in a tertiary hospital in Southern China between 2014 and 2019 and analyzed the related risk factors of poor prognosis using logistic regression. Overall, 28 cases were enrolled and the prevalence of talaromycosis in AIDS children was 15.3% (28/183). The median age of the onset was 8 years (range: 1–14 years). The typical manifestation of skin lesion with central umbilication was not common (21.4%). All the children had very low CD4+ cell counts (median 13.5 cells/μL, range: 3–137 cells/μL) on admission. 92.9% children were misdiagnosed and talaromycosis was only noted after positivity for HIV infection. 89.3% diagnoses of T. marneffei infections were based on positive blood cultures, with a long culture time (median 7 days, range from 3–14 days). The sensitivity of fungus 1,3-β-D-glucan assay was 63.2%. Amphotericin B was superior to itraconazole in the induction antifungal therapy of talaromycosis in HIV-positive children. A six-month follow-up revealed a 28.6% mortality. Lower ratio of CD4+/CD8+ and amphotericin B treatment not over 7 days predicted poor prognosis. Our retrospective study provided an overview and update on the current knowledge of talaromycosis in HIV-positive children. Pediatricians in endemic areas should be aware of mycoses to prevent misdiagnosis. 1,3-β-D-glucan assay did not show optimal sensitivity. Amphotericin B treatment over 7 days can improve poor prognosis.
相似文献Knowledge about the clinical and laboratory characteristics and prognosis of Talaromyces marneffei infection in children is limited. A retrospective study was conducted on pediatric patients with disseminated T. marneffei infection in a clinical setting. Extracted data included demographic information (age and sex), clinical features, laboratory findings, treatment, and prognosis. Eleven HIV-negative children were enrolled. The male/female ratio was 8:3. The median age of onset was 17.5 months (3.5–84 months). The mortality rate in these children was 36.36% (4/11). Seven children had underlying diseases. All of the children had multiple immunoglobulin abnormalities and immune cell decline. Ten children received voriconazole treatment, and most of the children (7/10) had a complete response to therapy at primary and long-term follow-up assessment; only three children died of talaromycosis. One patient recovered from talaromycosis but died of leukemia. The child who received itraconazole treatment also showed clinical improvement. No adverse events associated with antifungal therapies were recorded during and after the treatment. Talaromycosis is an indicator disease for undiagnosed severe immunodeficiencies in children. Awareness of mycoses in children by pediatricians may prompt diagnosis and timely treatment. Voriconazole is an effective, well-tolerated therapeutic option for disseminated T. marneffei infection in non-HIV-infected children.
