dc.description.abstract Aim The aim was to determine the epidemiology of invasive fungal infections at Chris Hani Baragwanath Hospital. The specific objectives were to determine the 1) risk factors, 2) clinical presentation, 3) laboratory abnormalities, 4) organisms and their susceptibilities and 6) outcome in neonates with positive blood or CSF fungal cultures at Chris Hani Baragwanath Hospital. Methods This was a retrospective record review of patients who had positive blood or CSF cultures. Patients were identified by a computerized microbiological surveillance database. The data was collected over a three-year period from January 2002 to December 2004. Patient hospital files were reviewed for clinical signs, full blood count (FBC), C-reactive protein (CRP) and outcomes. Fungal culture results were reviewed for susceptibilities. To identify risk factors a convenient cohort was compared to the patients with fungal sepsis. The data was analysed using a Statistica software package. Results There were 150 patients with fungal sepsis among admissions over this 3 yearperiod giving an incidence of 1.3 per 100 admissions. Thirty-nine records were not found thus 111 patient records were reviewed. The median birthweight was 1280g and the gestational age 30 weeks. The median age of onset was 16 days and 6.3% had early onset fungal sepsis. There were 61 males. Twenty-eight percent of patients were born to HIV positive mothers. Candida parapsilosis was the commonest (56%) organism isolated followed by C. albicans (43%). All the C. albicans isolates and 93% of the C. parapsilosis isolates were susceptible to amphotericin B. Fluconazole susceptibilities were reported as, 96% for C. albicans, and 60% of the C. parapsilosis as being susceptible. Central venous catheters (CVCs) (p=<0.001), the use of TPN (p=<0.001) and third generation cephalosporins were identified as risk factors associated with fungal sepsis. The all-cause mortality and Candida–related mortality were 30% and 23% respectively. The non-survivors had lower platelet counts (p=0.007) than the survivors. Patients with Gram-negative sepsis had lower platelet counts than the fungal group (p=<0.001) on the repeat laboratory parameters. Conclusion The incidence is 1.3 per 100 admissions. Risk factors associated with fungal sepsis are very low birthweight and gestational age, the use of TPN, CVCs and third generation cephalosporins. Candida parapsilosis is the common organism causing fungal sepsis in neonates. Candida albicans was associated with a higher mortality. Thrombocytopenia is not organism specific to fungal sepsis. en_US
