Urinary candidiasis: a prospective study in hospital patients
Abstract:
In a prospective study of 29 hospital inpatients with candiduria, yeasts were frequently isolated from the urine in the absence of symptoms and no serious deep fungal infection occurred. The prevalence of diabetes mellitus and urinary catheterisation was significantly increased in this group compared to the general hospital population. There was a high incidence of yeast species other than Candida albicans in the urine, non-albicans species constituting 39% compared with 18% from other sites (p less than 0.01).
Insights
Asymptomatic candiduria (yeast in urine) is common in hospital patients, especially those with diabetes or urinary catheters. Non-albicans Candida species are more frequent in urine than at other sites.
Area of Science:
- Medical Mycology
- Hospital Epidemiology
- Infectious Diseases
Background:
- Candiduria, the presence of yeast in urine, can occur in hospitalized patients.
- Risk factors for candiduria include diabetes mellitus and urinary catheterization.
- Understanding the prevalence and species distribution of urinary Candida is crucial for patient management.
Purpose of the Study:
- To investigate the occurrence and characteristics of candiduria in hospital inpatients.
- To identify risk factors associated with candiduria.
- To determine the species distribution of yeasts isolated from urine samples.
Main Methods:
- Prospective study design.
- Inclusion of 29 hospital inpatients with candiduria.
- Comparison of risk factor prevalence with the general hospital population.
- Yeast species identification from urine and other sites.
Main Results:
- Yeast frequently isolated from urine without symptoms; no serious deep fungal infections observed.
- Significantly higher prevalence of diabetes mellitus and urinary catheterization in candiduria patients.
- Non-albicans Candida species were more common in urine (39%) compared to other sites (18%).
Conclusions:
- Asymptomatic candiduria is a frequent finding in hospitalized patients, particularly those with diabetes or urinary catheters.
- Non-albicans Candida species represent a significant proportion of urinary yeast isolates.
- Further research may be needed to guide management strategies for asymptomatic candiduria.
