Bacterial vaginosis is associated with prematurity and vaginal fluid mucinase and sialidase: results of a controlled trial of topical clindamycin cream.

OBJECTIVE: The pathogenesis of preterm birth and other adverse pregnancy outcomes linked with reproductive tract infection remains poorly understood. Mucolytic enzymes, including mucinases and sialidases (neuraminidase), are recognized virulence factors among enteropathogens and bacteria that cause periodontal infection. Perturbation of maternal cervicovaginal mucosa membrane host defenses by such enzyme-producing microorganisms may increase the risk of subclinical intrauterine infection during pregnancy and thus increase risks of preterm birth. STUDY DESIGN: We prospectively evaluated vaginal fluid mucinase and sialidase and selected cervicovaginal bacteria along with pregnancy outcomes in 271 women. Within this study, women with bacterial vaginosis (16 to 27 week' gestation) were treated with 2% clinadmycin vaginal cream or placebo. Enzyme, microbial findings, treatment effects, and pregnancy outcomes were compared among drug- and placebo-treated women and control women without bacterial vaginosis. RESULTS: Presence of bacterial vaginosis at intake was associated with increased risk of preterm birth (relative risk 3.3, 95% confidence interval 1.2 to 9.1, p = 0.02), premature rupture of membranes (relative risk 3.8, 95% confidence interval 1.6 to 9.0, p = 0.002), and preterm premature rupture of membranes. Mucinase and sialidase activities were more commonly identified, and they occurred in higher concentrations, if present, in women with bacterial vaginosis (mucinase: 44.3% with bacterial vaginosis vs 27.4% without, p = 0.007; sialidase: 45% with bacterial vaginosis vs 12% without p < 0.001). Sialidase activity was associated with bacterial vaginosis-linked organisms (Gardnerella vaginalis, Mobiluncus spp, and Mycoplasma hominis) and Chlamydia trachomatis and yeast species; mucinase activity was associated only with bacterial vaginosis-linked microorganisms. Clindamycin, 2% cream, was effective treatment for bacterial vaginosis and temporarily reduced mucinase and sialidase activities. Topical treatment of bacterial vaginosis did not reduce risks of perinatal morbidity. Women with persistent or recurrent sialidase 8 weeks after treatment were at increased risk of preterm birth (15.6% vs 7.4%) premature rupture of membranes (30% vs 15%), and low birth weight (20% vs 3%, relative risk 6.8, 95% confidence interval 1.6 to 28.1). CONCLUSIONS: Persistence of sialidase-producing vaginal microorganisms in numbers sufficient to increase vaginal fluid sialidase activity may be a risk factor for possibly preventable subclinical intrauterine infection and preterm birth. This study confirms and further informs our understanding of the association of bacterial vaginosis and preterm birth; studies to evaluate whether systemic treatment for bacterial vaginosis can effectively reduce vaginal mucolytic enzymes and risks of prematurity and other morbid outcomes are continuing.

Patterns of adnexal inflammatory damage: Chlamydia, the intrauterine device, and history of pelvic inflammatory disease.

In a study of 204 consecutive infertile couples, 58 women with adnexal abnormalities consistent with prior pelvic infection were identified. The status of those 58 subjects with respect to prior pelvic infection, prior intrauterine device use, and serologic evidence of past chlamydial infection was correlated with the types of adnexal abnormalities identified. Women with serologic evidence of past chlamydial infection were more likely to exhibit severe adhesions and hydrosalpinx formation, and hydrosalpinx formation was related to a history of clinically detected pelvic infection.

Conservation of biodiversity of the coastal resources of Sundarbans, Northeast India: an integrated approach through environmental education.

The Indian Sundarbans, a diversified coastal wetland on the southern fringe of the State of West Bengal, harbors a luxuriant biodiversity and acts as a potential refuge of living marine resources. Girdled with thick mangrove foliage, this estuarine delta system offers an excellent nursery ground for most of the brackishwater finfish and shellfish. Since supply of hatchery-produced tiger prawn seed (Penaeus monodon) is highly inadequate in West Bengal, the aquaculture farms of this region largely depend on the supply from natural resources. Being motivated by a regular cash income, the majority of coastal people from Sundarbans have adopted prawn seed collection as their profession almost throughout the year as an important source of earning. The users are neither trained nor guided at any stage from collection to marketing and are fully dependent on traditional methods. They first sort out the tiger prawn seeds (mainly the postlarval stage PL 20) accounting only 0.25-0.27% of the total catch and thereafter the major portion of the haul are thrown away on the beach flats or the tidal mudflats. This wasted by-catch contains the juveniles of economic and uneconomic varieties of finfish and shellfish along with a bulk of holoplankters and meroplankters (non-target species). This practice causes several ecological and occupational consequences, namely, (i) the huge destruction of the pelagic biota that can lead to severe stock depletion as well as hamper the energy transference through the marine ecosystem food webs; (ii) constant dragging of nets along the coast and tidal creeks paves the way for soil erosion, uprooting the mangrove seedlings and saltmarsh vegetation; (iii) the water quality is deteriorating in the catchment areas due to mud erosion and (iv) due to constant contact with the seawater, the collectors are affected with waterborne diseases, skin infections, reproductive tract disease in women and many other contagious diseases. This paper, in addition to identifying the challenge to environmental quality and resource abundance, emphasizes the need for grass-root public education so that local people come to understand, support and implement sustainable resource conservation and environmental protection activities now and in the future. As a follow-up course of action, the authors have initiated a general awareness program for developing consciousness among the coastal people regarding proper use of natural resources. Initiatives are taken for educating coastal people by holding workshops and seminars with the use of educational resource materials. Exclusive awareness camps and grass root level training for coastal people are also being proposed as a future course of action by means of exhibitions, audiovisuals etc. It is proposed that local government bodies come forward to mitigate this problem with scientific and rational approaches and to take proper actions towards conservation.

Control of sexually transmitted diseases for HIV-1 prevention: understanding the implications of the Mwanza and Rakai trials.

Two randomised controlled trials of sexually transmitted disease (STD) treatment for the prevention of HIV-1 Infection, in Mwanza, Tanzania, and Rakai, Uganda, unexpectedly produced contrasting results. A decrease in population HIV-1 incidence was associated with improved STD case management in Mwanza, but was not associated with STD mass treatment in Rakai. Some reductions in curable STDs were seen in both studies. These trials tested different interventions in different HIV-1 epidemic settings and used different evaluation methods; the divergent results may be complementary rather than contradictory. Possible explanations include: differences in stage of the HIV-1 epidemic, which can influence exposure to HIV-1 and the distribution of viral load in the infected population; potential differences in the prevalence of Incurable STDs (such as genital herpes); perhaps greater Importance of symptomatic than symptomless STDs for HIV-1 transmission; and possibly greater effectiveness of continuously available services than of intermittent mass treatment to control rapid STD reinfection. Implications of the trials for policy and future research agenda are discussed.

Mot luuk problems in Northeast Thailand: why women's own health concerns matter as much as disease rates.

In this paper, we consider women's illness experiences, above and beyond the presence of clinically identifiable disease. In Northeast Thailand, epidemiological data suggest that the prevalence of major women's reproductive tract infections is relatively low and not a cause for significant public health attention. Conversely, we found that self-reported rates of gynecological complaints are high and a significant women's health concern in rural Northeast villages. Women's embodied experiences and interpretations of these complaints affect their lives dramatically. Moreover, women's responses to gynecological problems (regardless of diagnosed morbidity) constitute an important health issue in their own right. In this regard, we document the dangers of women's self-treatment practices that rely largely on small doses of medically inappropriate antibiotics, the manner in which family life and sexual relations are disrupted by fears that gynecological problems will progress to cervical cancer, health care seeking patterns and expectations from health staff, and most importantly, how women's concerns about the seriousness of recurrent ailments result in substantial suffering. This study demonstrates why attention to women's own health concerns is as important to address in health programs as rates of disease, and why common gynecological problems and work-related complaints are important to take seriously rather than dismiss as psychological or routine and expected. We argue that there is a strong need to conduct ethnographic research on women's health problems as a complement to, and not merely a support for, epidemiological research. An evidence-based approach to health policy needs to be accompanied by a more humanistic approach to understanding health care needs.

Living with infertility: experiences among Urban slum populations in Bangladesh.

This paper explores the perceived causes of infertility, treatment-seeking for infertility and the consequences of childlessness, particularly for women, among a predominantly Muslim population in urban slums of Dhaka in Bangladesh. In-depth interviews were conducted with 60 women and 60 men randomly selected from Urban Surveillance System clusters of the International Centre for Diarrhoeal Disease Research, Bangladesh. Case studies of 20 self-perceived infertile women who had previously participated in a study on the prevalence of sexually transmitted diseases and other reproductive tract infections were taken, and three traditional healers were interviewed as key informants. In both groups of respondents, the leading causes of infertility were perceived to be evil spirits and physiological defects in women and psychosexual problems and physiological defects in men. Herbalists and traditional healers were considered the leading treatment option for women, while for men it was remarriage, followed by herbalists and traditional healers. Childlessness was found to result in perceived role failure, with social and emotional consequences for both men and women, and often resulted in social stigmatisation of the couple, particularly of the woman. Infertility places women at risk of social and familial displacement, and women clearly bear the greatest burden of infertility. Successful programmes for dealing with infertility in Bangladesh need to include both appropriate and effective sources of treatment at community level and community-based interventions to demystify the causes of infertility, so that people know why infertility occurs in both men and women and and where best to seek care.

Cultural and biomedical meanings of the complaint of leukorrhea in South Asian women.

Among women in South Asia, the complaint of vaginal discharge (often called leukorrhea) is extraordinarily common. From a biomedical perspective, this symptom suggests that reproductive tract infection (RTI) is prevalent in the subcontinent; however, several recent studies provide evidence that the prevalence of RTI is relatively low. Women who do not have RTI frequently report the symptom of vaginal discharge. An anthropological perspective on the cultural meanings of leukorrhea can shed light on this puzzling phenomenon. According to Ayurvedic concepts of health and illness, genital secretions are considered a highly purified form of dhatu, or bodily substance, and loss of this precious substance is thought to result in progressive weakness or even death. Many South Asian women who complain of vaginal discharge also report a variety of somatic symptoms such as dizziness, backache and weakness. The link between unexplained gynaecological symptoms and mental health concerns has been explored by both psychiatrists and anthropologists in South Asia. Leukorrhea may represent a culturally shaped "bodily idiom of distress", in which concerns about loss of genital secretions reflect wider issues of social stress. Problems may arise when a symptom with deep cultural meaning is interpreted in a purely biomedical framework. In the syndromic approach to the treatment of sexually transmitted infections (STIs), health workers are trained to treat women presumptively based on history and a risk assessment, but without clinical or laboratory confirmation of infection. A recent evaluation of this approach demonstrates that many women who complain of vaginal discharge do not have RTI, and are inappropriately treated with antibiotics. It seems likely that women are over-reporting vaginal discharge because of its deep cultural meanings, meanings that need to be understood within an anthropological rather than biomedical framework.

The epidemiology of preterm labor.

There are many factors that are associated with preterm labor and delivery. These include maternal conditions such as medical illness, anemia and uterine malformation. They may be related to past events such as prior obstetric complication, previous preterm labor, cervical surgery or induced abortion. They may be intrinsic to the current pregnancy, such as reproductive tract infection, multifetal gestation, maternal age, short interpregnancy interval or prolonged menstrual conception interval. Maternal behaviors such as smoking and substance abuse can be risk factors for a short gestation. Demographic variables such as race, employment and socioeconomic status can also be associated with preterm labor. This article briefly reviews these subjects.

Sexual behaviour of infertile Nigerian women.

The objective of this study is to examine the sexual behaviour of infertile women in Ile-Ife, Nigeria and to elucidate to what extent women seeking treatment for secondary infertility are at risk of sexually transmitted diseases. In a 1-year study period, 236 secondarily infertile women (cases) and 472 pregnant women (controls) were interviewed using detailed open-ended questionnaires. Infertile women were at a significant risk of having multiple sexual partners OR 3.80 (1.97-7.32), reproductive tract infections OR 8.52 (5.08-14.37), early age at first sexual intercourse OR 19.13 (92.45-29.47) and poor condom use OR 4.50 (2.01-9.31) compared to controls (pregnant women). The paper discusses the reasons for the above observations and made recommendations aimed at reducing the infections related infertility in this subregion.

Why do women complain of vaginal discharge? A population survey of infectious and pyschosocial risk factors in a South Asian community.

BACKGROUND: Vaginal discharge is a common complaint, particularly among women in Asia. Although presumed to be caused by reproductive tract infections (RTIs), the association between the complaint and the presence of RTIs is weak. This study aimed to investigate the risk factors of the complaint of vaginal discharge. METHODS: We conducted a community-based survey of 3000 women aged 18-50 years, randomly sampled from a population in Goa, India. Women who gave informed consent were invited to participate in a structured interview, which elicited data on the primary outcome (the experience of current abnormal vaginal discharge) and psychosocial exposures: gender adversity; symptoms of somatoform disorders; and common mental disorders (CMD). All women were required to provide vaginal and/or urine samples for diagnosis of RTIs using gold standard laboratory tests. Risk factors were analysed using logistic regression with the binary outcome of the complaint of vaginal discharge. RESULTS: Of the 2494 women (83%) who agreed to participate, 14.5% complained of having an abnormal vaginal discharge. Stress was the most common causal attribution for the complaint. The final multivariate model found that high scores for CMD (OR 2.16, 1.4-3.2) and somatoform disorders (6.23, 4.0-9.7) and the use of an intrauterine contraceptive device (1.86, 1.0-3.4) were independently associated with the complaint. Low literacy (0.54, 0.4-0.8) and age >40 years (0.29, 0.2-0.4) were associated with a reduced risk. RTI were not associated with the complaint (1.24, 0.9-1.6). CONCLUSIONS: Psychosocial factors have the strongest association with the complaint of vaginal discharge. Syndromic management algorithms need refinement so that women with complaints that are non-infectious in aetiology are offered psychosocial interventions.
