OBJECTIVE: To investigate the etiological and clinical characteristics of immunocompetent patients with candidemia. METHODS: The clinical and microbiological data of patients diagnosed as candidemia admitted in Peking University Third Hospital from January 2010 to June 2016 were retrospectively analyzed. Underlying diseases, Candida spp. colonization, clinical manifestations, microbiological data, treatment and the outcome were compared between the HIV-negative immunocompromised (IC) and nonimmunocompromised (NIC) patients. RESULTS: A total of 62 cases diagnosed as candidemia were analyzed including 36 men and 26 women, with 16 to 100 years of age [(66.02±17.65) years]. There were 30 NIC and 32 HIV-negative IC patients respectively. In the NIC patients, there were 19 cases (19/30, 63.33%) with admission in intensive care unit (ICU), 21 (21/30, 70.00%) associated diabetes mellitus or uncontrolled hyperglycemia and 22 (22/30,73.33%) receiving invasive mechanical ventilation, while in the HIV-negative IC patients, there were 8 (8/32, 25.00%), 13 (13/32, 40.63%) and 7 (7/32, 21.88%) respectively (P<0.05). The NIC patients had higher acute physiology and chronic health evaluation (APACHE II) scores and sequential organ failure assessment (SOFA) scores both at admission (19.98±5.81, 6.04±6.14) and candidemia onset (25.61±6.52, 12.75±8.42) than the HIV-negative IC patients (APACHEII 15.09±5.82, 22.15±5.98) and SOFA 2.87±2.73, 7.66±5.64 respectively (P<0.05). In the NIC patients, twenty-one cases (21/30, 70.00%) died in hospital, while 14 cases (14/32, 43.75%) in HIV-negative IC. The crude mortality was significantly different between the two groups (P<0.05). By blood culture, Canidia albicans remained the the most prevalent isolates in all the patients. Clinical manifestation, Candida spp. colonization, etiology and drug susceptibility were also similar between NIC and HIV-negative IC patients (P>0.05). CONCLUSION Candidemia in NIC patients tends to occur in those who are much more critically ill, more often admitted in ICU, and more frequently have diabetes mellitus or uncontrolled hyperglycemia and receive invasive mechanical ventilation than HIV-negative IC patients. NIC patients also have poorer prognosis than HIV-negative IC patients. Clinical manifestations, and microbiological characteristics are similar between HIV-negative IC and NIC patients.

OBJECTIVETo investigate the clinical features of Candida albicans sepsis in preterm infants.

METHODSRetrospective analysis was performed on the clinical data of 13 preterm infants with Candida albicans sepsis, who were born at 28 to 36 weeks of gestational age and who weighed between 1400 and 2815 g.

RESULTSThe infants were infected with Candida albicans at the age of 19±11 d, with the main clinical manifestations being apnea, poor response, poor skin perfusion, blood oxygen concentration decrease, dark skin, yellowish skin, heart rate increase in the rest state, copious phlegm and difficulty in weaning from the ventilator. The infants showed significantly decreased platelet and increased C-reactive protein (CRP), platelet distribution width (PDW), alanine transaminase (ALT), creatine kinase isoenzyme-MB (CK-MB), total bilirubin (TBIL), creatine kinase (CK), and lactate dehydrogenase (LDH). CK and LDH were significantly decreased after 2 weeks of antifungal therapy. Only 3 cases developed drug resistance to fluconazole and these showed response when treated with voriconazole instead. Of the 13 cases, 10 were cured, 2 abandoned therapy and 1 died.

CONCLUSIONSThe clinical manifestations of Candida albicans sepsis are nonspecific in preterm infants. Infectious diseases are probably caused by Candida albicans in preterm infants 2-3 weeks after birth. Preterm infants show decreased platelet and increased CRP, PDW, ALT, CK-MB, TBIL, CK, and LDH when infected with Candida albicans.

Candidemia due to uncommon Candida spp. appears to be increasing in incidence. C. dubliniensis has been increasingly recovered from individuals not infected with HIV. Identification of C. dubliniensis can be problematic in routine clinical practice due to its phenotypic resemblance to C. albicans. We report the first case of C. dubliniensis candidemia in Korea, which occurred in a 64-yr-old woman who presented with partial seizure, drowsiness, and recurrent fever. Germ-tube positive yeast that was isolated from blood and central venous catheter tip cultures formed smooth, white colonies on sheep blood agar and Sabouraud agar plates, indicative of Candida spp. C. dubliniensis was identified using the Vitek 2 system (bioMerieux, USA), latex agglutination, chromogenic agar, and multiplex PCR. The blood isolate was susceptible to flucytosine, fluconazole, voriconazole, and amphotericin B. After removal of the central venous catheter and initiation of fluconazole treatment, the patient's condition gradually improved, and she was cleared for discharge from our hospital. Both clinicians and microbiologists should be aware of predisposing factors to C. dubliniensis candidemia in order to promote early diagnosis and appropriate treatment.

BACKGROUND: The incidence of candidemia in paediatric patients has increased over the last decade. We analysed the clinical characteristics of pediatric patients with candidemia over a 3-year period in Chonnam National University Hospital. METHODS: The medical records of 28 patients with candidemia diagnosed between 1996 and 1998 were retrospectively reviewed. Clinical characteristics including underlying illness, risk factors, therapy and outcome were assessed in relation to causing Candida species. RESULTS: The causing agents were mainly non-C. albicans species (24/28 cases, 81.5%). Underlying illnesses of patients were malignancy (n=12), surgical diseases (n=4), prematurity (n=2), and other medical illnesses of (n=10). Studies on clinical status at positive culture revealed antibiotic exposure (28/28, 100%), placement of central venous catheter (CVC, 16/28, 57.1%), use of total parenteral nutrition (15/28, 53.6%), and chemotherapy (14/28, 50%). Twenty patients were treated with amphotericin B and/or fluconazole and 15 patients'CVCs were removed. Overall mortality due to candidemia was 25%(7/28). CONCLUSIONS: These data show that most of pediatric candidemia cases are caused by non-C. albicans species and associated with a relatively lower mortality rate
