International Clinical Practice Guidelines for the Treatment of Acute Uncomplicated Cystitis and Pyelonephritis in Women: A 2010 Update by the Infectious Diseases Society of America and the European Society for Microbiology and Infectious Diseases

A Panel of International Experts was convened by the Infectious Diseases Society of America (IDSA) in collaboration with the European Society for Microbiology and Infectious Diseases (ESCMID) to update the 1999 Uncomplicated Urinary Tract Infection Guidelines by the IDSA. Co-sponsoring organizations include the American Congress of Obstetricians and Gynecologists, American Urological Association, Association of Medical Microbiology and Infectious Diseases-Canada, and the Society for Academic Emergency Medicine. The focus of this work is treatment of women with acute uncomplicated cystitis and pyelonephritis, diagnoses limited in these guidelines to premenopausal, non-pregnant women with no known urological abnormalities or co-morbidities. The issues of in vitro resistance prevalence and the ecological adverse effects of antimicrobial therapy (collateral damage) were considered as important factors in making optimal treatment choices and thus are reflected in the rankings of recommendations.

Douching in relation to bacterial vaginosis, lactobacilli, and facultative bacteria in the vagina

OBJECTIVE To study how frequency, recentness, and reason for douching impact bacterial vaginosis‐related vaginal microflora and the occurrence of cervical pathogens. Douching has been linked to bacterial vaginosis as well as to chlamydial cervicitis in some, but not all, studies. METHODS A total of 1200 women at high risk for sexually transmitted infections were enrolled from five clinical sites around the United States. Cross‐sectional, structured interviews were conducted and vaginal swabs were self‐obtained for Gram stain, culture, and DNA amplification tests for Neisseria gonorrhoeae and Chlamydia trachomatis. RESULTS Douching at least once per month was associated with an increased frequency of bacterial vaginosis. Those who douched recently (within 7 days) were at highest risk [odds ratio (OR) 2.1, 95% confidence interval (CI) 1.3, 3.1]. Douching for symptoms (OR 1.7, 95% CI 1.1, 2.6) and for hygiene (OR 1.3, 95% CI 1.0, 1.9) both related to bacterial vaginosis risk. The associations between douching and Gardnerella vaginalis, Mycoplasma hominis, and lack of hydrogen peroxide‐producing lactobacilli were similar to those between douching and bacterial vaginosis. Gonococcal or chlamydial cervicitis was not associated with douching. CONCLUSION Douching for symptoms or hygiene, particularly frequent or recent douching, was associated with bacterial vaginosis and bacterial vaginosis‐associated vaginal microflora, but not with gonococcal or chlamydial cervicitis.

Pneumonia in pregnancy

Objective:Historically, pneumonia during pregnancy has been associated with increased morbidity and mortality compared with nonpregnant women. The goal of this article is to review current literature describing pneumonia in pregnancy. This review will identify maternal risk factors, potential complications, and prenatal outcomes associated with pneumonia and describe the contemporary management of the varied causes of pneumonia in pregnancy. Results:Coexisting maternal disease, including asthma and anemia, increase the risk of contracting pneumonia in pregnancy. Neonatal effects of pneumonia in pregnancy include low birth weight and increased risk of preterm birth, and serious maternal complications include respiratory failure. Community-acquired pneumonia is the most common form of pneumonia in pregnancy, with Streptococcus pneumoniae, Haemophilus influenzae, and Mycoplasma pneumoniae accounting for most identified bacterial organisms. Beta-lactam and macrolide antibiotics are considered safe in pregnancy and are effective for most community-acquired pneumonia in pregnancy. Viral respiratory infections, including varicella, influenza, and severe acute respiratory syndrome, can be associated with maternal pneumonia. Current antiviral and respiratory therapies can reduce maternal morbidity and mortality from viral pneumonia. Influenza vaccination can reduce the prevalence of respiratory hospitalizations among pregnant women during influenza season. Pneumocystis pneumonia continues to carry significant maternal risk to an immunocompromised population. Prevention and treatment of Pneumocystis pneumonia with trimethoprim/sulfamethoxazole is effective in reducing this risk. Conclusions:Prompt diagnosis and treatment with contemporary antimicrobial therapy and intensive care unit management of respiratory compromise has reduced the maternal morbidity and mortality due to pneumonia in pregnancy. Prevention with vaccination in at-risk populations may reduce the prevalence and severity of pneumonia in pregnant women.

Observations concerning the microbial etiology of acute salpingitis.

Abstract OBJECTIVES : The specific aims of this study were (1) to describe the microbiologic characteristics of patients with acute salpingitis and (2) to determine the incidence of bacterial vaginosis in patients with acute salpingitis and whether bacterial vaginosis microorganisms were common upper-genital-tract isolates in these patients. STUDY DESIGN: Women with pelvic inflammatory disease underwent laparoscopy to confirm the diagnosis of acute salpingitis and for culture of the fallopian tubes and cul-de-sac. Endometrial and minute fimbrial biopsies were performed, and specimens were evaluated for evidence of inflammation. Bacterial vaginosis was diagnosed by vaginal Gram stain. RESULTS : Eighty-four patients had visually confirmed acute salpingitis. Neisseria gonorrhoeae or Chlamydia trachomatis was isolated from 65 (77.4%) patients. Vaginal microorganisms were isolated from the endometrium in 16 (31.4%) of 51 cases and from the cul-de-sac in 12 (14.3%) of 84 cases. Bacterial vaginosis was present in 61.8% of patients with acute salpingitis, and 100% of anaerobes isolated from the upper genital tract of patients with acute salpingitis were bacterial vaginosis micororganisms. These anaerobes were isolated from the upper genital tract in the absence of a concurrent gonococcal, chlamydial, or Haemophilus influenzae infection in only two cases. CONCLUSIONS : The initiation of acute salpingitis is predominantly due to the ascending spread of sexually transmitted microorganisms. Bacterial vaginosis is a common concurrent disorder of women with acute salpingitis, and bacterial vaginosis microorganisms are commonly isolated from the upper genital tracts of patients with pelvic inflammatory disease.

Bacterial vaginosis and risk of pelvic inflammatory disease.

BACKGROUND: Bacterial vaginosis commonly is found in women with pelvic inflammatory disease (PID), but it is unclear whether bacterial vaginosis leads to incident PID. METHODS: Women (n = 1,179) from 5 U.S. centers were evaluated for a median of 3 years. Every 6–12 months, vaginal swabs were obtained for gram stain and culture of microflora. A vaginal microflora gram stain score of 7–10 was categorized as bacterial vaginosis. Pelvic inflammatory disease was diagnosed by presence of either histologic endometritis or pelvic pain and tenderness plus one of the following: oral temperature greater than 38.3°C; sedimentation rate greater than 15 mm/hour; white blood count greater than 10,000; or lower genital tract detection of leukorrhea, mucopus, or Neisseria gonorrhoeae or Chlamydia trachomatis. RESULTS: After adjustment for relevant demographic and lifestyle factors, baseline bacterial vaginosis was not associated with the development of PID (adjusted hazard ratio 0.89, 95% confidence interval 0.55–1.45). Carriage of bacterial vaginosis in the previous 6 months before a diagnosis (adjusted risk ratio 1.31, 95% confidence interval 0.71–2.42) also was not significantly associated with PID. Similarly, neither absence of hydrogen peroxide–producing Lactobacillus nor high levels of Gardnerella vaginalis significantly increased the risk of PID. Dense growth of pigmented, anaerobic gram-negative rods in the 6 months before diagnosis did significantly increase a womans risk of PID (P = .04). One subgroup of women, women with 2 or more recent sexual partners, demonstrated associations among bacterial vaginosis, Gardnerella vaginalis, anaerobic gram-negative rods, and PID. CONCLUSION: In this cohort of high-risk women, after adjustment for confounding factors, we found no overall increased risk of developing incident PID among women with bacterial vaginosis.

Prevention of vaginal trichomoniasis by compliant use of the female condom.

BACKGROUND Several case-control studies suggest that the male condom protects women against some sexually transmitted diseases. The female condom is the first barrier device under the womans control that may be effective in the prevention of sexually transmitted diseases. GOAL OF THIS STUDY To determine if appropriate use of the female condom decreased the rate of recurrent vaginal trichomoniasis in previously diagnosed and treated women. STUDY DESIGN One hundred and four sexually active women with vaginal trichomoniasis were treated with metronidazole and assigned to a group using the female condom or a control group during a 45-day period of continued sexual activity. Fifty women served as controls, and 54 women were assigned to use the female condom. RESULTS Only 20 women used the female condom each time they had sexual intercourse. Reinfection with trichomonas occurred in 7/50 (14%) controls, in 5/34 (14.7%) noncompliant users, and in 0/20 compliant users of the female condom. CONCLUSION The compliant use of the female condom is effective in preventing recurrent vaginal trichomoniasis.

Fluconazole Susceptibility of Vaginal Isolates Obtained from Women with Complicated Candida Vaginitis: Clinical Implications

ABSTRACT Despite considerable evidence of azole resistance in oral candidiasis due to Candida species, little is known about the azole susceptibilities of the genital tract isolates responsible for vaginitis. The fluconazole susceptibilities of vaginal isolates obtained during a multicenter study of 556 women with complicated Candida vaginitis were determined by evaluating two fluconazole treatment regimens. Of 393 baseline isolates of Candida albicans, 377 (96%) were highly susceptible to fluconazole (MICs, <8 μg/ml) and 14 (3.6%) were resistant (MICs, ≥64 μg/ml). Following fluconazole therapy, one case of in vitro resistance developed during 6 weeks of monitoring. In accordance with the NCCLS definition, in vitro fluconazole resistance correlated poorly with the clinical response, although a trend of a higher mycological failure rate was found (41 versus 19.6% on day 14). By using an alternative breakpoint of 1 μg/ml, based upon the concentrations of fluconazole achievable in vaginal tissue, no significant differences in the clinical and mycological responses were observed when isolates (n = 250) for which MICs were ≤1 μg/ml were compared with isolates (n = 30) for which MICs were >1 μg/ml, although a trend toward an improved clinical outcome was noted on day 14 (odds ratio, >2.7; 95% confidence interval, 0.91, 8.30). Although clinical failure was uncommon, symptomatic recurrence or mycological relapse almost invariably occurred with highly sensitive strains (MICs, <1.0 μg/ml). In vitro fluconazole resistance developed in 2 of 18 initially susceptible C. glabrata isolates following fluconazole exposure. Susceptibility testing for women with complicated Candida vaginitis appears to be unjustified.

Wound infection after cesarean: effect of subcutaneous tissue thickness.

Objective To estimate the effect of the thickness of subcutaneous tissue at the surgery site on abdominal wound infection after cesarean delivery. Methods We measured the maximum vertical depths of subcutaneous incisions of women who had cesarean deliveries. The surgical technique for closure was standardized and drains were not used. Abdominal wound infection was defined by standard criteria and limited to the first 6 postoperative weeks. Additional demographic, intrapartum, and perioperative data previously associated with wound infection also were collected. Data were analyzed by Student t test, χ2 test, and multiple logistic regression. Results Wound infection occurred in 11 of 140 women (7.8%) who delivered by cesarean. Risk factors identified as significantly associated with wound infection by univariate analysis were thickness of subcutaneous tissue, maternal weight, and body mass index. Multiple logistic regression analysis confirmed subcutaneous tissue thickness as the only significant risk factor for wound infection, with a relative risk of 2.8 (95% confidence interval 1.3, 5.9). There were no significant differences between women who developed wound infections and those without infections in terms of selected demographics, duration of ruptured membranes, number of vaginal examinations, chorioamnionitis, type of skin incision, or duration of surgery. Conclusion Thickness of subcutaneous tissue appears to be the only significant risk factor associated with abdominal wound infection after cesarean delivery.

Douching and endometritis: results from the PID evaluation and clinical health (PEACH) study.

Background Douching has been related to risk of pelvic inflammatory disease (PID). Goal To examine the association between douching and PID in a large, multicenter, clinical trial of PID after adjustment for race/ethnicity. Study Design Interviews were conducted with 654 women who had signs and symptoms of PID. Vaginal Gram stains and upper genital tract pathology/cultures were obtained from all the women. Women with evidence of plasma cell endometritis and/or gonococcal or chlamydial upper genital tract infections were compared with women who had neither endometritis nor upper genital tract infection. Results Women with endometritis or upper genital tract infection were more likely to have douched more than once a month or within 6 days of enrollment than women who never douched. These associations remained after adjustment for confounding factors, after analysis of black women only; and among women with normal or intermediate vaginal flora but not bacterial vaginosis. Conclusion Among a predominantly black group of women with clinical PID, frequent and recent douching was associated with endometritis and upper genital tract infection.

Effectiveness of treatment strategies of some women with pelvic inflammatory disease: a randomized trial.

Objective: Among all women with pelvic inflammatory disease (PID), prevention of adverse reproductive consequences appears to be similarly achieved by outpatient treatment and inpatient treatment. We assessed whether outpatient is as effective as inpatient treatment in relevant age, race, and clinical subgroups of women with PID. Methods: Women with clinical signs and symptoms of mild-to-moderate pelvic inflammatory disease (n = 831) were randomized into a multicenter trial of inpatient treatment, initially employing intravenous cefoxitin and doxycycline compared with outpatient treatment consisting of a single intramuscular injection of cefoxitin and oral doxycycline. Comparisons between treatment groups during a mean of 84 months of follow-up were made for pregnancies, live births, time to pregnancy, infertility, PID recurrence, chronic pelvic pain, and ectopic pregnancy. Results: Outpatient treatment assignment did not adversely impact the proportion of women having one or more pregnancies, live births, or ectopic pregnancies during follow-up; time to pregnancy; infertility; PID recurrence; or chronic pelvic pain among women of various races; with or without previous PID; with or without baseline Neisseria gonorrhoeae and/or Chlamydia trachomatis infection; and with or without high temperature/white blood cell count/pelvic tenderness score. This was true even in teenagers and women without a previous live birth. Ectopic pregnancies were more common in the outpatient than the inpatient treatment group, but because these were so rare, the difference did not reach statistical significance (5 versus 1, odds ratio 4.91, 95% confidence interval 0.57–42.25). Conclusion: Among all women and subgroups of women with mild-to-moderate PID, there were no differences in reproductive outcomes after randomization to inpatient or outpatient treatment.
