High frequency of latent Chlamydia trachomatis infection in patients with rhegmatogenous retinal detachment

AIM： To determine the frequency of detection of ocular and extraocular Chlamydia trachomatis （CT） infection in non -high myopes with rhegmatogenous retinal detachment （RRD）. METHODS： This was a single-center, nonrandomized, prospective, case-control study. One hundred and four patients were divided into a study group with RRD （n= 63） and a control group with traumatic retinal detachment （n=41）. Samples of subretinal fluid （SFR）, conjunctival, urethral/cervical swabs, and blood were collected. The frequency of detection of CT infection in SRF samples was determined by polymerase chain reaction （PCR）, direct fluorescence assay （DFA） and cell culture, whereas that in conjunctival swabs was determined by PCR and DFA, and those in urethral/cervical swabs and blood were determined by DFA. Yates Chi-square test （with Bonferroni correction） and two-tailed Student＇s t-test were used for statistical analysis. RESULTS： SRF CT infection was detected more frequently in the study group （50.8%-71.4%） than in the control group （9.8%-12.2%） by all the methods used （P〈 0.01）. The frequency of detection of conjunctival CT infection by DFA was higher in the RRD patients compared with the controls （81.0% vs 24.4%, P=0.004）. The PCR detected conjunctival CT infection more often in the study group than in the controls （46.0% vs89.8%, P= 0.007）. The DFA detected CT in blood specimens almost as frequently as in urogenital specimens, for the RRD patients （61.2% vs 63.5%） and the controls （7.3% vs 9.8%）. CONCLUSION： CT infection is detected with high frequency in non-high myopes with RRD.

Patients with Cervical Ureaplasma Urealyticum and Chlamydia Trachomatis Infection Undergoing IVF/ICSI-ET: The Need for New Paradigm

Genital tract infections with ureaplasma urealyticum（UU） and chlamydia trachomatis（CT） are the most frequent sexually-transmitted disease worldwide. UU and CT infections are considered to be the leading cause for infertility and adverse pregnancy outcomes. However, little is known about the specific effect of cervical UU and CT infections on the etiology of female infertility, as well as the pregnancy outcomes of the patients undergoing in vitro fertilization/intracytoplasmic sperm injection-embryo transfer（IVF/ICSI-ET）. In order to find the association between cervical UU and/or CT infection and pregnancy outcomes, we conducted a retrospective case-control study on the patients undergoing IVF/ICSI-ET with cervical UU and/or CT infection. A total of 2208 patients who received IVF/ICSI-ET were enrolled in this study. Data on the general conditions, pregnancy history and clinical pregnant outcomes were analyzed in terms of the cervical UU and CT detection. Our results revealed that cervical UU and CT infections were the risk factors for ectopic pregnancy and tubal factor-induced infertility. Moreover, the pregnancy rate, abortion rate, ectopic pregnancy rate and premature birth rate in patients with UU and/or CT infections showed no significant difference when compared with the control group. We recommend that cervical UU and CT detection should be an optional item for infertility patients and clinical UU detection should differentiate the subtypes of cervical UU. Positive cervical UU and CT infections should not be taken as strict contraindications for IVF/ICSI-ET.

Longitudinal association of gonorrhea and bacterial vaginosis with repeat chlamydia diagnoses among U.S. Army women: A retrospective cohort analysis

Background: Historically, sexually transmitted infections have affected the health of the U.S. military. To determine whether gonorrhea, bacterial vaginosis, genital herpes, and trichomoniasis are predictors of repeat chlamydia diagnoses among U.S. Army women, medical data reported into the Defense Medical Surveillance System during the 2006–2012 period were analyzed.Methods: For all inpatient and outpatient medical records, the first and second International Classification of Diseases,version 9(ICD-9) diagnostic positions were reviewed for each chlamydia case to determine the occurrence of repeat diagnoses. The Andersen-Gill regression model, an extension of the Cox model for multiple failure-time data, was used to study associations between predictors and repeat chlamydia diagnoses.Results: Among 28,201 women with a first chlamydia diagnosis, 5145(18.2%), 1163(4.1%), 267(0.9%), and 88(0.3%)had one, two, three, and four or more repeat diagnoses, respectively. Overall, the incidence of repeat chlamydia was8.31 cases per 100 person-years, with a median follow-up time of 3.39 years. Gonorrhea(hazard ratio(HR)=1.58, 95%CI: 1.44–1.73) and bacterial vaginosis(HR=1.40, 95% CI: 1.09–1.79) were significant predictors for repeat chlamydia.These estimated hazard ratios were attenuated, but remained significant, after controlling for age, race/ethnicity,marital status, and military rank. No significant association was found for genital herpes(HR=1.13, 95% CI: 0.55–2.29)and trichomoniasis(HR=1.43, 95% CI: 0.43–4.68).Conclusions: This large cohort study suggests that gonorrhea and bacterial vaginosis were associated with repeat chlamydia diagnoses among U.S. Army women. These findings can be used in formulating new interventions to prevent repeat chlamydia diagnoses.

Extragenital chlamydia infection among active-duty women in the United States Navy

Background: Pharyngeal and anorectal reservoirs of gonorrhea(GC) and chlamydia(CT) are increasingly recognized among heterosexual women. While a number of studies performed at sexually transmitted disease(STD) clinics have found a high prevalence of extragenital GC/CT infection, such screening is typically not offered during routine primary care visits for women. We sought to define the prevalence of and factors associated with extragenital GC/CT among women in the U.S. Navy.Methods: We recruited servicewomen stationed in San Diego, California, between the ages of 18 and 25 who presented for an annual physical exam between January and September, 2017. Nucleic acid amplification testing was performed on swabs collected at endocervical, oropharyngeal and anorectal sites to assess the presence of GC/CT. An anonymous behavioral questionnaire was also administered to characterize sexual risk. Descriptive statistics were used to compare women with and without a prior history of any sexually transmitted infection(STI)(self-report) along with a current GC/CT diagnosis. This study was approved by the Institutional Review Board of the Uniformed Services University of Health Sciences.Results: Of the 75 patients who were approached, 60 subjects were enrolled in the study, including white 20(33.3%), black/African American 18(31.0%), Hispanic/Latina 13(21.7%) and Asian/Pacific Islander 9(15.5%) women. Among all the women, six(10.0%) were diagnosed with CT infection, all via endocervical exam. Of these, five(8.3%) had concurrent anorectal infection, including two cases(3.3%) accompanied by pharyngeal infection. Of the subjects, 15(25.0%) reported anal intercourse in their most recent sexual encounter, most of which was condomless(13/15, 86.7%). A high number of women who reported sex with a casual male partner(19/45, 42.2%) reported rarely or never using condoms;last, 41.7% consuming at least 3 drinks on a typical drinking day, and one-third of the reported drinking more than once per week.Conclusions: We found a high prevalence of anorectal CT infection, although no infections were detected without concurrent endocervical involvement. Nonetheless, the high prevalence of condomless anal intercourse reported by participants argues for further study and ongoing consideration of extragenital screening among high-risk patients. Behavioral interventions are also warranted given the high prevalence of sexual and related risk factors.

Impact of sexually transmitted infections on women health

Sexually transmitted infections (STIs) are the infections that can be transmitted from one sex partner, who already has such infection, to another. The causes of STIs in human are very well elucidated and their causative agents are identified as bacteria, parasites and viruses. The worldwide epidemiology of more than 20 types of STIs has been established, which includes diseases like Chlamydia, Gonorrhea, Genital herpes, HIV/ AIDS, HPV, Syphilis and Trichomoniasis. Though STIs affect both men and women indiscriminately, however, the pathophysiology of disease is more obvious among women. Other than abstinence, the most effective way to prevent the transmission or acquisition of STIs is to use a condom during sexual intercourse. Condoms are effective in decreasing the transmission of HIV. However, once contacted, STIs caused by bacteria or parasites can be treated with antibiotics. STIs caused by a virus may not virtually have any cure though the medicines may keep the disease under control. Correct usage of preventive measures greatly reduces but does not completely eliminate the risk of catching or spreading STIs.

Sexually Transmitted Infections (STIs) Knowledge Assessment of Adults in a US South Eastern Texas Region

The purpose of this cross-sectional descriptive study was to assess knowledge level regarding signs and symptoms, prevention, treatment of STIs among a sample of residents from Southeastern Texas. One hundred and fifty-seven participants age 18 and over responded to the 23 questionnaire items. Questionnaires were distributed to mostly public places such as hair salons, fitness centers, health centers, gas stations, apartments, and stores. Results indicated that 50.3% of participants reported syphilis was not curable;while over 61% reported gonorrhea was incurable. Over 64% of respondents reported they did know the symptoms for syphilis and over 70% believed that syphilis was vaccine preventable. The data collected from this study indicated that some residents from Southeast Texas lack basic information concerning Syphilis, Gonorrhea, and Chlamydia with regard to prevention, signs and symptoms, and treatment. The cost and effort to increase educational programs and educational messages appear to be justified. Implications for practice include increasing funding and efforts to provide more educational programs focusing on sexually transmitted disease prevention, health literary education to dispel the myths and stigma related to STIs and community wide collaboration efforts to increase awareness.

Chlamydia pneumoniae replicates in Kupffer cells in mouse model of liver infection

AIM: To develop an animal model of liver infection with Chlamydia pneumoniae (C. pneumoniae) in intraperito-neally infected mice for studying the presence of chlamy-diae in Kupffer cells and hepatocytes.METHODS: A total of 80 BALB/c mice were inoculated intraperitoneally with C. pneumoniae and sacrificed at various time points after infection. Chlamydiae were looked for in liver homogenates as well as in Kupffer cells and hepatocytes separated by liver perfusion with collagenase. C. pneumoniae was detected by both isola-tion in LLC-MK2 cells and fluorescence in situ hybridiza-tion (FISH). The releasing of TNFA-α by C. pneumoniae in vitro stimulated Kupffer cells was studied by enzyme-linked immunosorbent assay.RESULTS: C. pneumoniae isolation from liver homoge-nates reached a plateau on d 7 after infection when 6 of 10 animals were positive, then decreased, and became negative by d 20. C. pneumoniae isolation from sepa-rated Kupffer cells reached a plateau on d 7 when 5 of 10 animals were positive, and became negative by d 20. The detection of C. pneumoniae in separated Kupffer cells by FISH, confirmed the results obtained by culture. Isolated hepatocytes were always negative. Stimula-tion of Kupffer cells by alive C. pneumoniae elicited high TNF-α levels. CONCLUSION: A productive infection by C. pneumo-niae may take place in Kupffer cells and C. pneumoniae induces a local pro-inflammatory activity. C. pneumoniae is therefore, able to act as antigenic stimulus when local-ized in the liver. One could speculate that C. pneumoniaeinfection, involving cells of the innate immunity such as Kupffer cells, could also trigger pathological immune re-actions involving the liver, as observed in human patients with primary biliary cirrhosis.

Sexually Transmitted Infections among African-American Population of the Midwest United States

Background: Sexually transmitted infections (STIs) such as chlamydia and gonorrhea are commonly reported infections in the United States. Greater Omaha has had continually higher reported rates of chlamydia and gonorrhea for more than a decade compared to the rest of the state rates. Minority and young adults have been disproportionately affected. Purpose: The objectives of our study were to estimate the prevalence and to identify risk factors for chlamydia and gonorrhea among young adults. Methods: We conducted a cross-sectional survey with 310 young adults aged 19 -25 years between June 2011 and June 2012. The study collected socio-demographic, behavioral and other risk factors for STIs utilizing a pre-design standardized questionnaire. Gonorrhea and chlamydia status of the participants were established by testing urine samples using PCR-based diagnostic technique. Descriptive and multivariable regression analyses were used to examine risk factors for STIs. Results: About 12.6% survey participants had at least one STI test positive. Lower education was associated with STIs but was not statistically significant (Odd Ratio for no schooling was 8.24, 95% CI 0.93 -72.86, Odd Ratio for high school education was 2.05, 95% CI 0.25 -16.63 compared to associate or college level education). No other predictors were associated with STIs. The average age of the first sexual intercourse was lower, and the number of sexual partners was higher compared to their national counterparts. Conclusion: We found a higher percentage of STI-positive individuals compared to previously reported county-level estimates. Education was the single and most important predictor of positive STI status.

Research Progress on Chlamydia trachomatis Infection and Related Cytokines

Chlamydia trachomatis (Ct) infection can induce host cells to produce numerous cytokines.Cytokines play important roles in inflammatory response. Although inflammation can protect the body, persistent inflammation can lead to pathological changes and tissue damages. Further research should determine whether cytokine production directly affects development and outcomes of inflammation. This study summarizes Ct infection and related cytokines.

小檗碱的体外抗衣原体活性研究

研究旨在阐明天然产物小檗碱的体外抗衣原体活性。首先,通过测定小檗碱对沙眼衣原体L2和鼠衣原体MoPn包涵体形成数量和感染性子代滴度的影响,发现小檗碱对两种衣原体均呈浓度依赖性抑制。其次,采用CCK-8试剂盒测定化合物对细胞活力的影响,显示浓度不高于8μmol/L时小檗碱无明显宿主细胞毒性。借助宿主细胞和衣原体预处理实验,发现小檗碱不能直接作用于宿主细胞,仅能微弱地直接作用于衣原体而影响衣原体的感染过程。最后,分析小檗碱对衣原体增殖过程的影响。后加药和撤药实验结果显示,小檗碱主要作用于2~12 h的EB→RB转化阶段;长期耐受实验结果表明,小檗碱可以延缓衣原体的生长周期,但不能完全杀死衣原体。综上,小檗碱具有广谱的体外抗衣原体活性,对衣原体增殖过程的干扰作用强于对感染过程的影响。
