Chromoblastomycosis is an endemic mycoses which has been misdiagnosed or underdiagnosed in the past. This may be due to the clinicopathologic characteristics that it shares with other neglected tropical diseases such as leprosy and cutaneous tuberculosis. Correlating clinical findings with histopathologic cues will lead clinicians to correct diagnosis and subsequent treatment success.

OBJECTIVE:
To evaluate the clinical value of droplet digital PCR (ddPCR) in rapid and accurate diagnosis of invasive fungal infection (IFI) in neonates.
METHODS:
The highly conserved sequence of fungi 18S RNA was selected as the target sequence, and primers were designed to establish a ddPCR fungal detection system. Blood samples were collected from 83 neonates with high-risk factors for IFI and/or related clinical symptoms in the neonatal intensive care unit (NICU) of a hospital in Shenzhen, China. Blood culture and ddPCR were used for fungal detection.
RESULTS:
The ddPCR fungal detection system had a specificity of 100% and a sensitivity of 3.2 copies/μL, and had a good reproducibility. Among the 22 blood samples from neonates with a confirmed or clinical diagnosis of IFI, 19 were detected positive by ddPCR. Among the 61 blood samples from neonates who were suspected of IFI or had no IFI, 2 were detected positive by ddPCR.
CONCLUSIONS
The ddPCR technique can be used for the detection of neonatal IFI and is a promising tool for the screening and even diagnosis of neonatal IFI.

Journal of Experimental Hematology 2019;27(5):1678-1681
OBJECTIVE:
To analyze the diagnostic value of (1, 3) -β-D-glucan and galactomannan (GM) tests in the patients with acute leukemia complicated by invasive fungal disease, and explore the application of serological detection (G/GM) and lung CT for early diagnosis of invasive fungal disease (IFD).
METHODS:
A total of 493 patients with acute leukemia complicated by high risk invasive fungal infection, also receival G and GM tests, in Department of hematology of our hospital from June 2016 to December 2016 were selected and were divided into IFD-confirmed group (62 cases) including confirmed and clinical diagnesed IFD, and IFD-unconfirmed group (431 cases) including suspected IFD and non-IFD according to the diagnostic criteria of IFD. The results of G and GM tests in patients of 2 groups were analyzed, then the diagnostic efficacy of G and GM done and combination evaluated. In addition, 26 patients whose lung CT negative at hospitalization, moreover, presentation of changes in lung by CT during hospitalization and serological G and GM test positive were selected, and the difference of time between serological that postive and presentation of changes in lung by CT were compared for the estimation of early diagnotic value.
RESULTS:
The positive rate of (1, 3) -β-D-glucan in IFD-confirmed group and IFD-unconfirmed group was 56.5% and 10.4%, respectively. Meanwhile, that of galactomannan test was 41.9% and 9.0%, respectively. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of (1, 3) -β-D-glucan was 56%, 90%, 44% and 92%, and that of galactomannan was 42%、91%、40% and 93%, respectively. Moreover, the combination of (1, 3) -β-D-glucan and galactomannan could raise the sensitivity to 69% and specificity to 98%. The positive results of serological detection (G/GM) come earlier about five days than CT changes.
CONCLUSION
Both (1, 3) -β-D-glucan and galactomannan test have high sensitivity and specificity, and the combination of them can improve the diagnostic efficacy, and make the clinical antifungal therapy more precisely. In the early clinical diagnosis of IFD, the positive results of serological detection coming earlier than lung CT.

OBJECTIVE:
To investigate the clinical characteristics, prevention and treatment of invasive fungal disease (IFD).
METHODS:
The clinical data of 164 patients who met the diagnostic criteria of IFD in our center from January 2012 to January 2015 were retrospectively analyzed. The incidence, clinical characteristics, related factors, treatment methods and prognosis were analyzed.
RESULTS:
Among 1289 cases of blood diseases, 164 cases suffered from IFD with inciduce of 12.7%. The main infection sites were as followed: lung, blood and gastrointestinal tract, with incidence of 84.2%, 5.5% and 3% respectively. The funge was found in 35 cases by detection; among fungi, the detected rate of candida albicans. aspergillus and candida glabrata was more high with 51.5%, 20% and 14.3% respectively. Among 164 childen with blood deseases complicated by IFD, 36 cases gained complete remission, 97 cases gained partial remission, 10 cases were stable, 11 cases were progressive and 10 cases died, the overall effective rate reached 81.1%. The univariate analysis showed that the gramulopenia, granulocyte recovery, long-term use of corticosteroid and immuno-suppressive agents, as well as different grades of diagnosis were significant factors affecting the efficacy of antifungal therapy for blood disease children with IFD, the multivariate analysis further showed that the granulocyte recovery and diagnosis grades were independent prognostic factors affecting the therapeutic efficacy for IFD children. The overall survival rate of IFD children with 12 weeks of antifungal treatnment was 81.7%, out of which the survival rate of IFD children at 12 weeks of treatment with itraconazole, voriconazole, amphotericin B and caspofungin was 81.4%, 80%, 69.4% and 97.1% respectively, there were significant differences in survival rate between each other by long rank test. In addition of caspofungin, the other 3 kinds of drugs had toxic side effects of different degrees, but IFD children could tolerated these effects after symptomatic treatment.
CONCLUSION
The incidence of IFD in children with blood deseases in our hospital is 12.7%, the lung is most common infective site, moreover patogens of IFD mainly is candida. The promotion of granulocyte recovery and early stratified diagnosis can contribule to the treatment of IFD. For the IFD children with better economic condition, the caspofungin is a potent antifungal agent with high efficacy, low toxicity and better prognosis.

OBJECTIVE:
To assess the efficacy and safety of fluconazole in the prophylaxis of invasive fungal infection in very low birth weight (VLBW) infants.
METHODS:
Databases including PubMed, Embase, the Cochrane Library, Wanfang Data, Weipu, and CNKI were searched for randomized controlled trials (RCTs) of prophylactic fluconazole in VLBW infants. Review Manager 5.3 software was used to perform a Meta analysis of the included studies.
RESULTS:
A total of 12 RCTs were included, involving 1 679 VLBW infants. The Meta analysis showed that prophylactic fluconazole significantly reduced the incidence of invasive fungal infection (RR=0.44, 95%CI: 0.27-0.71, P<0.001), the incidence of fungal colonization (RR=0.31, 95%CI: 0.24-0.40, P<0.001), and the mortality during hospitalization (RR=0.74, 95%CI: 0.58-0.94, P=0.01) compared with the control group. There were no significant differences between VLBW infants using different doses of fluconazole in the incidence of invasive fungal infection and fungal colonization (P>0.05). No significant differences were found in the incidence of fluconazole resistance and complications between the fluconazole and control groups (P>0.05).
CONCLUSIONS
Prophylactic fluconazole can effectively and safely prevent invasive fungal infection in VLBW infants, even at a small dose.

9.Consensus on diagnosis and treatment of invasive fungal infection in patients with severe liver disease.
Chinese Journal of Hepatology 2022;30(2):159-168
The prognosis of severe liver disease combined with invasive fungal infection (IFI) is poor, and the clinical manifestations are often atypical. Moreover, most of the antifungal drugs are metabolized in the liver, with severe toxicities and side effects, making clinical diagnosis and treatment difficult. The Professional Committee for Hepatology, the Chinese Research Hospital Association and the Hepatology Branch of China Medical Association organized relevant experts to formulate an expert consensus based on the characteristics of patients with severe liver disease combined with IFI, in order to provide reference for medical personnel in making decisions on the diagnosis and treatment.
