[PMID: 38850689 DOI: 10.1016/j.diagmicrobio.2024.116394] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 05/20/2024] [Accepted: 06/04/2024] [Indexed: 06/10/2024]
Abstract
Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), Ureaplasma urealyticum (UU) are the common sexually transmitted pathogens and lead to genital diseases, highly prevalent all around the world. The objective of this study was to analyze the prevalence of NG, CT and UU among outpatients in central China. A total of 2186 urogenital swabs were collected from the patients and the NG, CT and UU pathogens were testing with RT-PCR method, meanwhile the medical records were obtained from the hospital information system. The overall infection rates of NG, CT and UU were 4.57 %, 6.63 % and 48.81 % respectively, showed the prevalence of UU was higher than NG and CT. The younger people had the highest infection rate of NG (10.81 %), CT (20.54 %) and UU (54.59 %). Single infection (89.09 %) was significant higher than co-infection (10.91 %), and the CT-UU co-infection was the prominent pattern (66.41 %). There were an obvious sex difference, the prevalence of NG and CT were significant higher in male, whereas UU was higher in female. Our study could contributed a better understanding of the prevalence of NG, CT and UU, facilitating to the development of effective screening, prevention and treatment policies.

Characteristics of reproductive tract infections caused by common pathogens among the outpatients of reproductive medicine center in Putian: retrospective study. BMC Infect Dis 2024; 24:315. [PMID: 38486167 PMCID: PMC10941379 DOI: 10.1186/s12879-024-09180-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Accepted: 02/26/2024] [Indexed: 03/17/2024] Open
Abstract
BACKGROUND This study aims to explore the infection and age distribution of Ureaplasma urealyticum (UU), Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Herpes simplex virus type II (HSV II) among the outpatients of Reproductive Medicine Center in Putian, Fujian Province to provide a clinical basis for the early diagnosis and treatment of various reproductive tract diseases and infertility in this region. METHODS A total of 1736 samples of secretions and exfoliated cervical cells were collected from the outpatients of the Reproductive Medicine Center of the Affiliated Hospital of Putian University from December 2021 to April 2023. The infections of UU, CT, NG and HSVII were detected by real-time fluorescence polymerase chain reaction (PCR), and the infection statuses of the patients with different genders, ages and diagnoses were analysed. RESULTS Among the 1736 patients, 611 were male and 1125 were female. The male patients had higher UU infection rate but lower HSV II infection rate than the female patients. No significant difference in CT and NG infection rates was observed between the genders. The CT infection rate gradually decreased with the increase in the age. The difference in UU, NG and HSV II infection rates among the different age groups was not statistically significant. For UU infection, the male infertile patients had the highest rate of 37.72% (172/456). Meanwhile, the differences in CT, NG and HSV II infection rates among the different diagnosis groups were not statistically significant. Among the male and female infertile patients, the CT infection rate was the highest in the 21-25 years of age group at 11.11% (2/18) and 9.47% (9/95), respectively. No statistically significant difference in UU, CT, NG and HSV II infection rates was observed among the different age groups of patients diagnosed in relation to the family planning guidance and between the male and female patients with other diagnoses results. CONCLUSIONS This study showed that UU was the most frequently identified pathogen in infertile men in Putian, Fujian Province. The CT infection rate was the highest in people under 20 years old, and the infection showed a tendency toward young individuals. Therefore, the publicity of sexual health knowledge must be strengthened, and the prevention and treatment of venereal diseases among young and middle-aged people must be improved. Moreover, the pathogen infection is related to infertility to a certain extent, which is conducive to clinical diagnosis and treatment.

Prevalence of Ureaplasma species among patients at a tertiary hospital in China: a 10-year retrospective study from 2013 to 2022. Eur J Clin Microbiol Infect Dis 2023; 42:1425-1437. [PMID: 37843646 DOI: 10.1007/s10096-023-04678-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Accepted: 10/03/2023] [Indexed: 10/17/2023]
Abstract
BACKGROUND Ureaplasma species are common pathogens of the urogenital tract and can cause a range of diseases. Unfortunately, there is still a scarcity of large-scale and cross-sectional studies on the prevalence of Ureaplasma species in China to clarify their epidemic patterns. METHODS This study retrospectively analyzed the data of 18667 patients who visited Peking Union Medical College Hospital for showing various symptoms of (suspected) Ureaplasma species infection during the period 2013-2022. The overall prevalence of Ureaplasma species was calculated, and subgroup analyses were conducted in view of gender, age, specimen types, and diagnosis in every year within the period studied. Furthermore, previous literature that reported on the prevalence of Ureaplasma species in various regions of China was searched and summarized. RESULTS The overall positive rate of Ureaplasma species in this study reached 42.1% (7861/18667). Specifically, the prevalence of Ureaplasma species was significantly higher in female patients, while the highest detection rate was found in the 21-50 age group. From 2013 to 2022, there were no significant differences in positive rates of Ureaplasma species among years. However, the detection rate of Ureaplasma species was decreased in COVID-19 period (2020-2022) compared to pre-COVID-19 period (2017-2019). In view of the distribution of patients, outpatients predominated, but the detection rate was lower than inpatients. Urine was the most common specimen type, while cervical swabs had the highest detection rate of Ureaplasma species. When grouped by diagnosis, the highest positive rate of Ureaplasma species was seen in patients with adverse pregnancy outcomes and the lowest rate in patients with prostate disease. The previous literature, although heterogeneous, collectively suggested a high prevalence of Ureaplasma species in China. CONCLUSIONS Our study has shown that Ureaplasma species have reached a significant prevalence in China and demands adequate attention.

Front Public Health 2023; 11:1228048. [PMID: 38089034 PMCID: PMC10711282 DOI: 10.3389/fpubh.2023.1228048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Accepted: 11/07/2023] [Indexed: 12/18/2023] Open
Abstract
Background Ureaplasma urealyticum, Chlamydia trachomatis, and Neisseria gonorrhoeae are the prevalent causes of several genital diseases worldwide; however, their characteristics in different genders have not been well documented in Shanghai. The aim of this study is to describe the prevalence of common pathogens among outpatients, considering variations by gender and age. Methods From January 1, 2016, to December 31, 2021, the urogenital swabs of 16216 outpatients aged 3-95 years from two general hospitals in Shanghai were collected. All participants' swabs were investigated for U. urealyticum, C. trachomatis, and N. gonorrhoeae by isothermal RNA-based simultaneous amplification and testing. The basic information of all participants was also recorded, including age and gender. The chi-square test was used to compare the prevalence between different genders, age groups, and infection patterns. Results There were 5,744 patients (35.42%) with positive samples whose ages ranged from 7 to 80 years (33.23 ± 8.63 years), and 62.14% of them were women. The most common pathogen detected was U. urealyticum (85.08%). The highest prevalence rate of all three pathogens was found in patients aged ≤ 20 years (40.53%, 95% confidence intervals [CI]: 33.80%-47.63%). The prevalent rate of U. urealyticum was higher in men (33.36%, 95% CI: 32.19%-34.55%). The overall prevalence rates of U. urealyticum, C. trachomatis, and N. gonorrhoeae were 30.14% (95% CI: 29.44%-30.85%), 6.00% (95% CI: 5.64%-6.38%), and 2.10% (95% CI: 1.89%-2.33%). Conclusions Ureaplasma urealyticum was the most prevalent pathogen in the population, and its prevalence decreased with age. Young men aged ≤ 20 years were more frequently infected. Regular screening for sexually transmitted pathogens in different genders and age groups are warranted, particularly in young men.

Prevalence of syphilis and chlamydia trachomatis infection among female sex workers in Jiangsu, China: Results from a multicenter cross-sectional and venue-based study. Front Public Health 2022; 10:1018724. [PMID: 36388309 PMCID: PMC9659951 DOI: 10.3389/fpubh.2022.1018724] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2022] [Accepted: 10/14/2022] [Indexed: 01/28/2023] Open
Abstract
Background Female sex workers (FSWs) are considered highly vulnerable to sexually transmitted infections (STIs), but available data on the prevalence of STIs among FSWs in China is limited at a provincial level. This study aimed to evaluate the prevalence of STIs and risk factors among FSWs in Jiangsu, China. Methods We conducted a multicenter cross-sectional study in seven cities of Jiangsu to investigate the prevalence and risk factors associated with HIV and other STIs. Blood and urine were collected to test for HIV, syphilis, Hepatitis C (HCV), Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) infections. Results We enrolled 3,580 FSWs. The overall prevalence of bacterial STIs was 6.2% (5.4%-7.0%). The prevalence of HIV, syphilis infection, HCV, NG and CT were 0.1% (95%CI, 0.0-0.2), 1.8% (95%CI, 1.4-2.3), 0.3% (95%CI, 0.1-0.5), 0.3% (95%CI, 0.2-0.5) and 4.3% (95%CI, 3.6-5.0), respectively. Most FSWs (85.6%) reported consistent condom use with clients in the past month. Only 10.6% of FSWs reported group sex, and 68.3% self-reported HIV testing in the previous year. According to the multivariable model, having group sex in the past year (aOR, 2.521, 95%CI: 1.366-4.651) and HIV infection (aOR, 26.260, 95%CI: 2.432-283.563) were associated with a higher risk of syphilis infection. Migrants (aOR, 1.669, 95%CI: 1.163-2.395), having a history of STIs in the past year (aOR, 4.601, 95%CI: 1.003-21.118), and NG infection (aOR, 38.549, 95%CI: 11.214-132.514) were associated with a higher risk of CT infection. On the contrary, FSWs aged older than 25 were associated with lower risk of syphilis infection (25-34: aOR, 0.339, 95%CI: 0.151-0.763) and CT infection (25-34: aOR, 0.503, 95%CI: 0.316-0.802; ≥35: aOR, 0.578, 95%CI: 0.362-0.925). Conclusion This study's prevalence rates of syphilis and CT infections show the need to promote comprehensive STIs control and prevention strategies, including behavioral intervention and STIs screening, especially in younger high-risk populations. With the increasing coverage of HIV testing, integrating other STIs screening with HIV testing may be a reasonable way to implement comprehensive STIs control and prevention.

Abstract
BACKGROUND Sexually transmitted infections (STIs) can have serious consequences, and the global STI incidence remains high. However, there is little information on the frequency of STIs with multiple pathogens according to age. Accordingly, we conducted a study to determine the trends of coinfection with sexually transmitted pathogens according to age in the Republic of Korea from 2018 to 2020. METHODS From January 2018 to December 2020, 65,191 samples of swab, urine, and other types submitted for STI screening were obtained from U2Bio Co. Ltd. (Seoul, Republic of Korea). Multiplex polymerase chain reaction, a sensitive and rapid method for simultaneous detection of STIs caused by multiple different pathogens, was performed using an AccuPower STI4C-Plex Real-Time PCR kit, AccuPower STI8A-Plex Real-Time PCR kit, and AccuPower STI8B-Plex Real-Time PCR kit with an Exicycler 96 Real-Time Quantitative Thermal Block. RESULTS Of the 65,191 samples tested, 35,366 (54.3%) tested positive for one or more sexually transmitted pathogens. The prevalence of coinfections with two or more sexually transmitted pathogens was inversely proportional to age. Furthermore, the rates of coinfection with sexually transmitted pathogens and age distribution differed according to sex and the sexually transmitted pathogen type. CONCLUSION This study confirmed that a significant proportion of patients with STIs are coinfected with multiple pathogens. Public health managers could use these results to recognize and prevent STIs according to age.

Prevalence of Chlamydia trachomatis Among Pregnant Women, Gynecology Clinic Attendees, and Subfertile Women in Guangdong, China: A Cross-sectional Survey. Open Forum Infect Dis 2021; 8:ofab206. [PMID: 34235228 PMCID: PMC8253043 DOI: 10.1093/ofid/ofab206] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Accepted: 04/21/2021] [Indexed: 11/22/2022] Open
Abstract
Background Chlamydia trachomatis (CT) is a major cause of infertility
and adverse birth outcomes, but its epidemiology among childbearing-age
women remains unclear in China. This study investigated the prevalence of CT
and associated factors among Chinese women aged 16–44 years who were either
(1) pregnant, (2) attending gynecology clinics, or (3) subfertile. Methods We conducted a cross-sectional survey and recruited participants from
obstetrics, gynecology, and infertility clinics in Guangdong between March
and December 2019. We collected information on individuals’ sociodemographic
characteristics, previous medical conditions, and sexual behaviors.
First-pass urine and cervical swabs were tested using nucleic acid
amplification testing. We calculated the prevalence in each population and
subgroup by age, education, and age at first sex. Multivariable binomial
regression models were used to identify factors associated with CT. Results We recruited 881 pregnant women, 595 gynecology clinic attendees, and 254
subfertile women. The prevalence of CT was 6.7% (95% CI, 5.2%–8.5%), 8.2%
(95% CI, 6.2%–10.7%), and 5.9% (95% CI, 3.5%–9.3%) for the above 3
populations, respectively. The subgroup-specific prevalence was highest
among those who first had sex before age 25 years and older pregnant women
(>35 years). The proportion of asymptomatic CT was 84.8%, 40.0%, and
60.0% among pregnant women, gynecology clinic attendees, and subfertile
women, respectively. Age at first sex (<25 years), multipara, and ever
having more than 1 partner increased the risk of CT. Conclusions Childbearing-age women in China have a high prevalence of CT. As most women
with CT were asymptomatic, more optimal prevention strategies are urgently
needed in China.

Abstract
Objective This study aimed to determine the association of asymptomatic sexually transmitted infections (STIs), including Ureaplasma urealyticum (UU), Mycoplasma hominis (MH), Mycoplasma genitalium, Chlamydia trachomatis, and herpes simplex virus type 2, with high-risk human papillomavirus (hrHPV) in cervical intraepithelial lesions and neoplasms. Methods A total of 320 hrHPV-positive and 160 hrHPV-negative women were divided into high-grade squamous intraepithelial lesion (HSIL) + invasive cervical cancer and low-grade squamous intraepithelial lesion + normal subgroups, respectively, on the basis of pathological cervical lesions. Cervical brush specimens were amplified and hybridized using polymerase chain reaction kits. Results MH was associated with hrHPV infection, but not with specific hrHPV genotypes or with single or multiple genotypes. Coinfection of hrHPV and UU serotype 14 (Uup14) showed an increased risk of HSILs and cervical carcinoma (odds ratio [OR]: 12.541, 95% confidence interval [CI]: 3.625–43.390). U. urealyticum biovar (Uuu) and Uup1 infections showed a similar increased risk (OR: 11.646, 95% CI: 1.493–90.850; OR: 7.474, 95% CI: 1.140–49.015, respectively) without hrHPV. Conclusions Asymptomatic STIs are widespread. This study shows an association between UU subtypes and cervical cancer, providing new insight into cervical lesion etiology. Screening for MH, Uup14, Uup1, and Uuu is important under different hrHPV statuses.
