Identification of novel markers for uncomplicated lower genital tract infections and upper genital tract pathology due to Chlamydia trachomatis

Pelvic inflammatory disease in the adolescent and young adult: An update

Pelvic inflammatory disease (PID) is an infection of the female upper genital tract that is typically polymicrobial with classic core involvement of Neisseria gonorrhoeae and/or Chlamydia trachomatis, though other endogenous flora from the vagino-cervical areas can be involved as well. It is often a sexually transmitted disease but other etiologic routes are also noted. A variety of risk factors have been identified including adolescence, young adulthood, adolescent cervical ectropion, multiple sexual partners, immature immune system, history of previous PID, risky contraceptive practices and others. An early diagnosis and prompt treatment are necessary to reduce risks of PID complications such as chronic pelvic pain, ectopic pregnancy and infertility. Current management principles of PID are also reviewed. It is important for clinicians to screen sexually active females for common sexually transmitted infections such as Chlamydia trachomatis and provide safer sex education to their adolescent and young adult patients. Clinicians should provide comprehensive management to persons with PID and utilize established guidelines such as those from the US Centers for Disease Control and Prevention (CDC).

Pelvic inflammatory disease in the adolescent: a poignant, perplexing, potentially preventable problem for patients and physicians

PURPOSE OF REVIEW

The present review considers recent pelvic inflammatory disease literature. It remains a difficult condition to accurately diagnose and manage in the adolescent woman. Failure of accurate diagnosis and prompt management leads to complications, including chronic pelvic pain and infertility.

RECENT FINDINGS

Annual chlamydia screening of sexually active adolescents is an important method for early identification of this common cause of this disorder. Youth with positive screens can be lost for treatment if effective follow-up plans are not in place in clinical practice. The intrauterine device is not a risk factor for this condition in adolescents and is a recommended contraceptive device in sexually active adolescent women. A variety of chlamydial antigens are being used to help differentiate lower genital infection from upper genital disorder. Clinicians are not following established protocols for its diagnosis and management.

SUMMARY

Sequelae can be reduced in adolescent women if clinicians continue with regular chlamydia screening in sexually active adolescent women, have a low index of suspicion for pelvic inflammatory disease, carefully follow accepted treatment protocols, and teach youth comprehensive sexuality education including regular condom use. Funded research is needed to develop improved diagnosis and management tools as well as a chlamydia vaccine.

Chlamydia trachomatis and Genital Mycoplasmas: Pathogens with an Impact on Human Reproductive Health

The most prevalent, curable sexually important diseases are those caused by Chlamydia trachomatis (C. trachomatis) and genital mycoplasmas. An important characteristic of these infections is their ability to cause long-term sequels in upper genital tract, thus potentially affecting the reproductive health in both sexes. Pelvic inflammatory disease (PID), tubal factor infertility (TFI), and ectopic pregnancy (EP) are well documented complications of C. trachomatis infection in women. The role of genital mycoplasmas in development of PID, TFI, and EP requires further evaluation, but growing evidence supports a significant role for these in the pathogenesis of chorioamnionitis, premature membrane rupture, and preterm labor in pregnant woman. Both C. trachomatis and genital mycoplasmas can affect the quality of sperm and possibly influence the fertility of men. For the purpose of this paper, basic, epidemiologic, clinical, therapeutic, and public health issue of these infections were reviewed and discussed, focusing on their impact on human reproductive health.

The molecular fingerprint of high grade serous ovarian cancer reflects its fallopian tube origin

High grade serous ovarian cancer (HGSC), the most lethal and frequent type of epithelial ovarian cancer (EOC), has poor long term prognosis due to a combination of factors: late detection, great metastatic potential and the capacity to develop resistance to available therapeutic drugs. Furthermore, there has been considerable controversy concerning the etiology of this malignancy. New studies, both clinical and molecular, strongly suggest that HGSC originates not from the surface of the ovary, but from the epithelial layer of the neighboring fallopian tube fimbriae. In this paper we summarize data supporting the central role of fallopian tube epithelium in the development of HGSC. Specifically, we address cellular pathways and regulatory mechanisms which are modulated in the process of transformation, but also genetic changes which accumulate during disease progression. Similarities between fallopian tube mucosa and the malignant tissue of HGSC warrant a closer analysis of homeostatic mechanisms in healthy epithelium in order to elucidate key steps in disease development. Finally, we highlight the importance of the cancer stem cell (CSC) identification and understanding of its niche regulation for improvement of therapeutic strategies.

Unveiling New Molecular Factors Useful for Detection of Pelvic Inflammatory Disease due to Chlamydia trachomatis Infection

Background. Untreated Chlamydia trachomatis infections in women can result in disease sequelae such as pelvic inflammatory disease (PID), ultimately culminating in tubal occlusion and infertility. While nucleic acid amplification tests can effectively diagnose uncomplicated lower genital tract infections, they are not suitable for diagnosing upper genital tract pathological sequelae. Objective. The purpose of this paper was to provide a comprehensive review of new molecular factors associated with the diagnosis and prognosis of PID. Material and Methods. The literature was searched using the key words “Chlamydia trachomatis infections,” “pelvic inflammatory disease,” and “molecular factors” in the PubMed database. Relevant articles published between 1996 and 2012 were evaluated. Conclusions. The use of new molecular factors could potentially facilitate earlier diagnosis and prognosis in women with PID due to C. trachomatis infection.
