Utility and Pitfalls of β-D-Glucan for Diagnosis and Response Monitoring of Chronic Disseminated Candidiasis in Paediatric Cancer Patients.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundβ-D-Glucan (BDG) is a useful but nonspecific biomarker in patients with suspected invasive fungal diseases including Pneumocystis pneumonia. Little is known, however, about its utility for response monitoring in chronic disseminated candidiasis (CDC). PATIENTS AND
methodsWe describe the utility and pitfalls of serum BDG in paediatric cancer patients with suspected CDC. BDG in serum was measured serially (i.e., 5 to 10 times of a time period of 200 to 400 days) by a commercially available assay (Fungitell; Associates of Cape Cod, MA, USA) and values were correlated to patient- and disease-related variables.
resultsFive paediatric patients (4f/1 m; 4-18 years) with acute lymphoblastic leukaemia (n = 4) and Ewing sarcoma (n = 1) followed between 2013 and 2024 were included. CDC was located in the spleen (n = 5), liver (n = 4), lungs (n = 3), CNS (n = 2), kidney (n = 1), and skin (n = 1); and diagnosed based on imaging, a positive blood culture (n = 1), a positive BDG assay in serum (n = 5), and absence of other etiologies. Patients received IV liposomal amphotericin B and/or caspofungin, followed by fluconazole orally for 184 to > 365 days, respectively. BDG concentrations in serum (35 time points) stayed elevated for prolonged periods of time, were independent of clinical symptoms, and returned to normal with resolution of imaging findings in the four leukaemia patients. In the patient with Ewing sarcoma, liver biopsy performed 5 months after diagnosis due to lack of improvement revealed disseminated aspergillosis.
conclusionsBDG in serum is useful for microbiological diagnosis and monitoring of probable CDC; however, it remains a non-specific fungal biomarker whose results need to be scrutinised in patients who do not respond to treatment as expected.
