Antichlamydia Antibodies and Sperm Quality among Male Partners of Infertile Couples in Nigeria

: The impact of Chlamydia trachomatis on semen quality has been studied with varied results. Aim: To determine the prevalence of antichlamydial antibodies and their relationship with sperm quality among male partners of infertile couples in Enugu, South-East Nigeria. Materials and Methods: It was a cross-sectional study of infertile male partners of couples attending infertility clinics at the University of Nigeria Teaching Hospital (UNTH) Ituku-Ozalla, Enugu, Nigeria. Their sera were assayed for antichlamydial antibodies, and semen analysis and culture were done for each participant. Results: Two hundred and eighty-two (282) male partners of infertile couples were studied. Infertility was commoner among participants aged 40 years or more (45.1%) and was mainly of the "primary type" (62.1%). Antichlamydia antibody was detected in 156 (55.3%) participants and was significantly associated with sperm quality (P = 002; OR = 2.294; 95% CI = 1.36­3.88). Overall, 81 (28.7%) had abnormal sperm quality. The sperm count, progressive motility, and vitality were significantly lower in participants with abnormal sperm quality than those with normal sperm quality (P < 0.001) while morphology, volume, and liquefaction time did not differ significantly (P > 0.05). Staphylococcus aureus was the predominant organism isolated from culture (122/282, 43.3%) while Streptococcus species were the least (4/262, 1.4%). There was significantly more Staphylococcus aureus isolated from the semen of participants that were seropositive to antichlamydial antibodies than those that were seronegative (80/156, 51.3% vs. 42/126, 33.3%; OR = 2.105; 95% CI = 1.30­3.42; P = 0.003). Conclusion: The prevalence of antichlamydial antibodies among male partners of infertile couples in Enugu, Nigeria is high and there is a significant association with sperm quality, sperm count, and bacterial isolates in seminal culture. Male partners of infertile couples in Enugu should be screened for antichlamydial antibodies and appropriate treatment offered wherever indicated. There is a need for increased public awareness and advocacy campaigns on the impact of Chlamydia infection on male factor infertility. This primary preventive measure may help in reducing the burden of Chlamydia infection and male factor infertility.

Effect of fluvastatin sodium on the risk factors of atherosclerosis in previous coronary heart disease after infection with chlamydia pneumonia / 中国生化药物杂志

Objective To investigate the effect of fluvastatin sodium on the risk factors of atherosclerosis in patients with previous coronary heart disease.Methods 58 cases meeting the inclusion criteria and diagnosed coronary heart disease history of chlamydial infection were selected and randomly divided into study group and control group, 29 cases in each group, the control group were given routine treatment, study group on the basis of conventional treatment of fluvastatin sodium(20 mg pertime, once daily) treatment.A total of 4 weeks treatment for a course, the blood lipid and vascular endothelial function, matrix metalloproteinases and inflammatory factor levels were determined before and after treatment, and adverse reactions were recorded between the two groups.Results Compared with the control group, the total cholesterol ( TC ) , triglyceride ( TG ) , low density lipoprotein cholesterol(LDL-C) and lipid comprehensive index(LCI) in study group after treatment were lower, the high density lipid-cholesterol(HDL-C) was higher, the soluble intercellular adhesion molecule-1(sI-CAM-1) and endothelin-1(ET-1) were lower, the NO was higher, matrix metalloproteinase-1 (MMP-1), MMP-9 and tissue inhibitor of metalloproteinase-1(TIMP-1) were lower, and tumor necrosis factor-α(TNF-α), interleukin 1 beta(IL-1β), high-sensitivity c-reactive protein( Hs-CRP ) and IL-6 were lower ( all P <0.05 ).All patients were followed up, only slight gastrointestinal adverse reaction, there was no significant difference in adverse reactions between the two groups.Conclusion The fluvastatin sodium can reduce the blood lipid, the level of matrix metalloproteinases, improve vascular endothelial function and inflammatory state, with high safety.

Infección por Chlamydia Trachomatis en un grupo de mujeres de alto riesgo, trabajadoras del sexo en Costa Rica / Infection by Chlamydia Trachomatis in a group of women of high risk, workers of sex in Costa Rica

Las clamidias son los patógenos más importantes en las enfermedades de transmisión sexual en todo el mundo. Sólo para Estados Unidos se estima que ocurren más de 4 millones de infecciones clamidiales por año. En Costa Rica pocos estudios de la infección por Chlamydia trachomatis (CT) han sido publicados por la falta de introducción de pruebas sensibles y específicas para su tamizaje y diagnóstico. Este estudio pretende determinar la presencia de la infección por CT en un grupo de mujeres trabajadoras de sexo (MTS) para demostrar la necesidad de diagnóstico y tomar las medidas adecuadas de prevención y control. En un estudio descriptivo transversal prospectivo, un total de 457 MTS fueron analizadas, se obtuvieron muestras de endocervical y orina, así como datos epidemiológicos. La prueba de PCR Roche Diagnostic fue usada para detectar la infección por C. Trachomatis. Se determina un 14.7 por ciento de prevalencia de infección afectando principalmente a los grupos etarios de 16 a 34 años así, como su relación con comportamientos de riesgo tales como, edad temprana de inicio de relaciones sexuales (10 a 19 años), baja escolaridad (66 por ciento primaria o menos), múltiples compañeros sexuales (50.7 por ciento de 11 a 50 por semana), no uso del preservativo (43.8 por ciento). No se encontró relación entre la infección por CT y el diagnóstico clínico sintomatológico lo que evidencia la necesidad de la implementación de un método de diagnóstico como las pruebas de amplificación nucleica de gran sensibilidad y especificidad como, su aplicación en diferentes tipos de muestras: endocervicales, uretrales, orina que permitan la detección y prevención de la infección, para brindar los tratamientos oportunos y la disminución de la morbilidad y la transmisión.

The Chlamydia are the most important pathogens in the sexual transmission diseases over the world. An estimated of 4 million Chlamydia infection occurs annually in the United States. In Costa Rica, few studies of the Chlamydia trachomatis (CT) infection have been published because of the lack of sensitive and specific testing introduction methods for screening and diagnostic. This study tries to determine the presence of the infection by CT in a group of women sex workers (WSW) to demonstrate that we must implemented the diagnostic and take the measures from prevention and control. In one descriptive, prospective and transversal study, a total of 457 WSW were analyzed. Endocervicales, urine samples and epidemiological data were obtained from the study. C. Trachomatis infection was detected with the PCR Roche Diagnostic Test. In this study a 14.7% of prevalence is determined, affecting mainly groups of people from 16 to 34 years old. Besides, a connection with early sexual intercourse (10 to 19 years), low schooling (primary 66% or less), multiple sexual partners (50.7% from 11 to 50 per week), non use of condom (43.8%) was found. In the study there was not relation between infection by CT and the clinical diagnostic symptoms that demonstrates the necessity of the implementation of a diagnostic method, like nucleic acid amplifi cation tests, for the great sensitivity and specifi city, and its application in different specimens: urethral, endocervicales, urine that allow the detection and prevention of the infection, to offer the proper treatments and the reduction of the morbidity and the transmission.

Situation, clinical characteristics and the value of PCR in diagnosis of urogenital chlamydia infection

The study aimed to investigate the situation, clinical characteristics and the value of PCR in diagnosis of urogenital chlamydia infection. During 3 months (6/2003-9/2003) we had studied 416 patients with urogenital discharge attending at laboratory department of the National Institute of Dermatology of Vietnam (NIDV). They had been tested for the C.T by using PCR and /or Hexagon (EIA). Results: 94 patients were detected C.T infection, the rate is 22.6%. In which, number of the women is 3.66 times higher than the men. The highest frequency of C.T infection is group of age from 25 to 34, and patients who live in urban. The most common symptom is cervicitis (in female) and urethritis, pain or burning during urenation (in male). PCR was positive in some cases which were negative with Hexagon test.

Prevalence of Chlamydia Infection in Infertile Women: Application of Polymerase Chain Reaction for Detection of Chlamydia trachomatis DNA / 대한산부인과학회잡지

OBJECTIVE: Endocervical infection of Chlamydia trachomatis is one of the most common sexually transmitted diseases(STD) in women, and it usually disseminates into the upper genital tract, especially at the uterine exploration. This study was performed to investigate the prevalence rate of endocervical Chlamydia trachomatis in infertile women with the application of polymerase chain reaction(PCR) for the detection of Chlamydia trachomatis DNA. METHODS: From March, 1996 to October, 1999, endocervical swabs were obtained in 101 infertile patients at SNUH. Chlamydia trachomatis DNA was extracted and amplified by a commercially available Amplicor Chlamydia trachomatis PCR kit(Roche Diagnostics, Branch burg, USA). The clinical characteristics of infertile patients were reviewed and analyzed. RESULTS: The mean age was 31.0 years old, and the mean duration of infertility was 43.4 months. The prevalence rate of endocervical Chlamydia trachomatis in infertile patients was 4.0%(4/101). There was no significant difference in the prevalence rate of Chlamydia trachomatis infection among the different infertility factor groups: 7.1%(2/28) in tubal-peritoneal factor group, 8.3%(1/12) in cervical factor group, and 8.3%(1/12) in unexplained infertility group. Two patients suffered from chronic cervicitis. CONCLUSION: The application of PCR for the detection of Chlamydia trachomatis DNA was a rather rapid and accurate diagnostic method. Therefore, it could be recommended as a diagnostic test applicable to the routine infertility work-up.
