Local markers for prediction of women at higher risk of developing sequelae to Chlamydia trachomatis infection.

PROBLEM: Chlamydial infections are often associated with various fertility-related disorders. Serological prediction of these has limitations, as they do not differentiate between past and current infections. Thus, we looked for local markers that could predict more precisely women at higher risk of developing severe complications. METHOD OF STUDY: A total of 320 Chlamydia trachomatis positive women with or without fertility disorders were tested for the prevalence of immunoglobulin A antibodies to synthetic peptides of chlamydial heat-shock protein 60 (cHSP60) and cHSP10 along with cervical interferon-gamma (IFN-gamma) and serum C-reactive protein (CRP) levels. RESULTS: Positive IFN-gamma level was the single best predictor for fertility disorder [odds ratio (OR) 15.4]. The predictive value of IFN-gamma could be significantly improved only by the addition of CRP test (OR 37.9). CONCLUSION: Positive IFN-gamma levels in cervical washes along with elevated CRP levels could be used to predict women who are at higher risk of developing fertility disorders.

Sublingual versus vaginal route of misoprostol for cervical ripening prior to surgical termination of first trimester abortions.

BACKGROUND: Sublingual and vaginal routes of misoprostol have been found to be effective for pharmacological ripening prior to surgical termination of first trimester abortions. We conducted this study to compare the effectiveness and acceptability of sublingual versus vaginal route of misoprostol for cervical priming prior to vacuum aspiration (VA). METHODS: In this prospective clinical trial, a total of 100 women with period of gestation between 6 and 12 weeks scheduled for day surgery abortion were sequentially allocated into two groups of 50 each. All participating women received 400 microg of misoprostol 3 h prior to VA either by sublingual (self-administered at home) or by vaginal route (inserted by the doctor in hospital) after wetting the tablet with water. RESULTS: Demographic characteristics of both the groups were comparable. For all periods of gestation, sublingual misoprostol significantly improved cervical dilatation (p<0.001) and reduced the time duration of surgery (p<0.001) compared to vaginal group without increasing the side effects. Mean pain score of the sublingual group was 2.7+/-1.1 as compared to 3.2+/-1.6 of the vaginal group (p=0.57). Misoprostol tablet was found intact in the vagina of three patients and was only partially absorbed amongst five patients at the time of VA. CONCLUSION: Sublingual route is an effective and convenient alternative to vaginal administration of misoprostol for cervical dilatation. It can be conveniently self-administered at home thereby decreasing hospital stay and cost. It also has a good patient acceptability rate.

Determinants of early discontinuation of IUCD use in rural northern district of India: a multivariate analysis and its validation.

The purpose of this study was to examine the determinants for early discontinuation among IUCD users in a rural district of northern India. Multivariate analysis indicated several significant predictors of early discontinuation of IUCD use. The risk of discontinuation increased more than two times in the presence of factors such as more than usual amount of menstrual flow before insertion and intermenstrual bleeding after insertion. Similarly, residence or alternatively those coming from villages without health centres were nearly two times more likely to discontinue. Menstrual disturbance increased the risk nearly three-fold. If only those women who report normal menstrual cycles had IUCDs inserted, it is very likely that the high discontinuation rate due to menstrual disturbance could be reduced. Knowledge about the IUCD and its effectiveness decreased the risk of early discontinuation but was not a statistically significant factor in multivariate analysis. Validation of the developed model was done by using the bootstrapping method and the model was found to be 18% noisy. These findings may help family planning providers in counselling and practice.

Comparison between the sublingual and oral route of misoprostol for pre-abortion cervical priming in first trimester abortions.

BACKGROUND: Misoprostol has been used for achieving cervical priming before suction evacuation (SE) by the oral or vaginal route, although both routes have their shortcomings. We evaluated the efficacy of the sublingual versus oral route of misoprostol for cervical priming before SE. METHODS: A prospective clinical trial was carried out in 100 women with a period of gestation of between 6 and 12 weeks who were sequentially allocated to two groups of 50 each. Both groups received 400 microg of misoprostol 3 h prior to SE by either the sublingual or the oral route. RESULTS: Demographically, both groups were similar. For all periods of gestation, sublingual misoprostol significantly improved cervical dilation (P<0.001) with a reduction in duration of surgery (P=0.024) compared with the oral route. Mean (+/- SD) pain scores for the sublingual and oral groups were similar (2.6 +/- 1.4 versus 3.5 +/- 1.1). No major complications occurred in either of the two groups. CONCLUSION: the sublingual route is an effective alternative to oral administration of misoprostol for cervical dilation. To the best of our knowledge, this is the first study to compare the efficacy of the sublingual versus the oral route of misoprostol for cervical priming before SE.

Enhanced immunocompetent cells in chlamydial cervicitis.

OBJECTIVE: To investigate changes in cell-mediated immunophenotypes by flow cytometry in endocervical secretions and peripheral blood in women with Chlamydia trachomatis infection. STUDY DESIGN: Fifty women attending the gynaecology outpatient department of Safdarjang Hospital, New Delhi, India, with signs and symptoms of cervicitis were enrolled. All patients underwent endocervical screening for C trachomatis (direct fluorescence antibody test [DFA]), and any coinfection with Candida (Gram stain), bacterial vaginosis (Gram stain), Neisseria gonorrhoeae (Gram stain), Trichomonas vaginalis (wet mount) and HIV (enzyme-linked immunosorbent assay) was ruled out. Flow cytometry was done to investigate changes in immunophenotypes in endocervical secretions and peripheral blood using monoclonal antibodies for surface markers (CD3, CD4, CD8, CD19, CD45 and CD83). Data were analyzed by chi2 test, while means were compared using Student's t test. RESULTS: C trachomatis positivity was found to be 36% (n = 18). Forty-eight patients constituted the study population since 2 patients coinfected with Candida, bacterial vaginosis and T vaginalis were excluded. A statistically significant enhancement in CD4+, CD8+ and dendritic cellular phenotypes was observed in the endocervical secretions of Chlamydia-positive patients, while B cells showed no marked difference. In the parallel study of matched peripheral blood, immunophenotypes did not show statistically significant results. CONCLUSION: Increased influx of CD4+, CD8+ and dendritic cells in the endocervix is an indication of cell-mediated immunity in response to C trachomatis infection. Local immune response in the cervical region is independent of systemic response. The mechanism by which local mucosal and systemic immune cells interact to repel or enhance susceptibility to C trachomatis infection requires further study.

Role of sublingual misoprostol for cervical ripening prior to vacuum aspiration in first trimester interruption of pregnancy.

This is a prospective randomized clinical trial evaluating, for the first time, the effectiveness of sublingual route of misoprostol for cervical priming prior to vacuum aspiration (VA). The trial included 100 women seeking first trimester abortion who were sequentially randomized into two groups of 50 each. Patients of study group received 400 microg sublingual misoprostol 3 h prior to VA while those of the control group did not receive any premedication for cervical ripening. For all periods of gestation between 6 and 12 weeks, misoprostol significantly reduced pain score, blood loss, time duration and rate of complications without increasing the side effects. Sublingual misoprostol is an effective alternative to mechanical cervical dilatation. It can be self-administered and has a good patient-acceptability rate. As no study has evaluated the role of sublingual route of misoprostol for cervical priming before VA, wider studies should be done to advocate its routine use.

Predominance of Chlamydia trachomatis serovars associated with urogenital infections in females in New Delhi, India.

Screening for Chlamydia trachomatis was done for 280 endocervical swab samples by PCR specific for endogenous plasmid. Age dependency was seen in symptomatic patients, with a high chlamydial prevalence rate (28%) found in younger women. Genotyping by restriction fragment length polymorphism analysis of omp1 PCR-positive samples showed serovars D, E, and F to be the most prevalent.

Serum copper levels in carcinoma of ovary and cervix.

The role of serum copper level (SCL) as a diagnostic and prognostic tool in genital tract malignancies was evaluated. SCL was employed as a marker for response to treatment (surgical/radiotherapy). 129 women attending gynaecology outpatient department or admitted in the gynecology ward were studied. Of these 77 patients in the disease (study) group were proven cases of genital tract malignancies and 52 served as controls. Outcome measures studied were: SCL levels estimated before initiation of any treatment i.e. surgery/radiotherapy; thereafter, at two weeks after completion of treatment. Follow up of the study subjects was done between 4-8 weeks and 8-10 weeks, when the patients were evaluated for any recurrence of disease and SCLs were also estimated. Kruskal-Wallis one-way analysis of variance determined whether values varied significantly among the different groups studied. Mean SCLs were found to be significantly elevated in cases of Ca ovary (n = 15), early CaCx (n = 14) and late CaCx (n = 48), as compared to the control group, comprising of women with no signs and symptoms of malignancy (n = 52). SCLs decreases significantly (P < 0.001) after treatment of Ca ovary and CaCx. These results indicate a possible clinical usefulness of estimating serum copper levels in women with genital tract cancer and suggest a role for SCL in the evaluation of the disease activity and as a prognostic tool in the management of genital malignancies.

Reliability of detecting rRNA sequences of Chlamydia trachomatis with fluorescence in situ hybridization without amplification.

OBJECTIVE: To use fluorescence in situ hybridization (FISH) using ribosomal RNA (rRNA) oligonucleotide probes as the target nucleic acid for the detection of Chlamydia trachomatis. STUDY DESIGN: Suitable sequences selected from the rRNA sequence of C trachomatis were labeled with a fluorescent dye and used in FISH for detecting chlamydial inclusion bodies and/ or elementary bodies in paraformaldehyde-fixed urogenital swab samples. The sensitivity and specificity of the FISH assay were compared with those of the polymerase chain reaction (PCR) using plasmid primers. Positive known C trachomatis-infected McCoy cells were used as positive controls. Urogenital swab specimens that were C trachomatis negative on culture and PCR were used as negative controls. RESULT: Among the 128 samples included in the study, FISH was positive in 28 (21.8%) and PCR in 33 (25.7%). A significant correlation was found between the 2 detection methods. Results of PCR and FISH were consistent in 115 of the 128 samples (R = 0.89). Thirteen samples showed discordant results. Of these, 9 FISH negative samples were PCR positive and 4 FISH positive samples were PCR negative. CONCLUSION: FISH was a highly specific and fairly sensitive technique for detecting C trachomatis. Signal amplification techniques and use of different fluorophores may further increase the sensitivity of this technique.

Polymerase chain reaction for detection of endocervical Chlamydia trachomatis infection in women attending a gynecology outpatient department in India.

OBJECTIVES: To detect Chlamydia trachomatis infection by polymerase chain reaction (PCR) in symptomatic women attending a gynecology clinic in a city hospital and in randomly selected slum dwellers. STUDY DESIGN: Endocervical specimens were collected from 350 women with genitourinary complaints (group I) and 53 slum dwellers (group II). Samples were analyzed by PCR, direct fluorescence assay (DFA) and Giemsa stain cytology for detection of C trachomatis and compared for their sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). RESULTS: The prevalence of endocervical C trachomatis infection was 43.1% and 24.5% in groups I and II, respectively. The sensitivity, specificity, PPV and NPV of PCR were 80.0%, 75.0%, 66.6% and 85.7%, respectively, when DFA was considered true positive. The percent increment in detection of C trachomatis by PCR was 15.3%. CONCLUSION: Giemsa stain cytology has low sensitivity and specificity; hence, it cannot be recommended for use as a diagnostic technique. It appears that PCR can be used routinely in Chlamydia diagnosis and in screening selected populations. The high positivity of C trachomatis infection in urban slum dwellers is cause for concern.
