- Abstract:
- Background: The prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae, Ureaplasma urealyticum, Mycoplasma hominis and Trichomonas vaginalis in the patient population of the STD outpatient clinic of the Department of Dermatology and Venereology Graz has not yet been collected and statistically analyzed. Objective: The goal of this thesis is to asses the prevalence of above mentioned pathogens among patients of the STD outpatient clinic Graz. Methods: This retrospective study involved the collection of data of all patients tested for Chlamydia trachomatis, Neisseria gonorrhoeae, Ureaplasma urealyticum, Mycoplasma hominis and Trichomonas vaginalis in the period of time from 05/2006 to 05/2011 at the STD outpatient clinic of the Department of Dermatology and Venereology Graz. The following parameters were collected: age, sex and infection status. After completing the collection, all data were anonymized and analyzed statistically via Microsoft Excel and SPSS. Based on the three appointed parameters (age, sex, infection status) two different observation periods and consecutively two test populations were established. All data collected within the period of time from 05/16/2006 to 05/26/2011 were used for the evaluation of the parameters age and sex. To ensure statistical comparability of the collected data on the parameter infection status for each pathogen over the years only the years from 2007 to 2010 (full 12 months) were taken into account. Results: In total 1669 patients, 1159 (69%) men and 510 (31%) women, were tested. The overall mean age of patients was at 36.1 years. Among all of the tested patients, 657 (39.4%) were tested positive for at least one of the pathogens of interest. Out of the 657 patients tested positive, 431 (n = 66%) were of male and 226 (n = 34%) of female gender. The average age in patients tested positive for at least one pathogen was at 31.8 years. The most common pathogen to be found in the study population from 2007 to 2010 in both male and female patients was U. urealyticum (n = 319/61.8%), followed by C. trachomatis (n = 108/20.9%), N. gonorrhoeae (n = 74/14.3%), M. hominis (n = 11/2.1%), und T. vaginalis (n = 4/0.8%). The STD outpatient clinic Graz was most commonly frequented by patients between the age of 20 and 29 years. 392 men (33.8%) and 159 women (31.1%) were part of this age group. With increasing age (>30 years) the frequency of consultations at the Graz STD clinic in both sexes declined. Conclusion: The results of the statistical evaluation of the data collected at the STD clinic Graz show that the prevalence of C. trachomatis and N. gonorrhoeae remains on a constant level, while U. urealyticum and M. hominis show declining numbers for the studied period of time. A significant trend for T. vaginalis can not be determined, because of the small amount of infections detected.
