Epidemiology, pathogenesis and treatment of pelvic inflammatory disease.

Pelvic inflammatory disease, the infection and inflammation of the female upper genital tract, is a common cause of infertility, chronic pain and ectopic pregnancy. Diagnosis and management are challenging, due largely to a polymicrobial etiology which is not fully delineated. Signs and symptoms of this syndrome vary widely, further complicating diagnosis and treatment. Due to the potential for serious sequelae, a low threshold for diagnosis and treatment is recommended. Since pelvic inflammatory disease has a multimicrobial etiology including Neisseria gonorrhoeae, Chlamydia trachomatis and anaerobic and mycoplasmal bacteria, treatment of pelvic inflammatory disease should be broad spectrum. Recent treatment trials have focused on shorter duration regimens such as azithromycin and monotherapies including ofloxacin, although data are sparse. Research comparing sequelae development by differing antimicrobial regimens is extremely limited, but will ultimately shape future treatment guidelines. Several promising short-duration and monotherapy antibiotic regimens should be evaluated in pelvic inflammatory disease treatment trials for compliance, microbiological and clinical cure, and reduction of subsequent adverse reproductive and gynecological morbidity.

Association between allelic variants in cytokine genes and preeclampsia.

OBJECTIVE: The purpose of this study was to examine the relationship between cytokine genotypes and preeclampsia. STUDY DESIGN: We conducted a case-control study that examined cytokine genotypes among 150 primiparous preeclamptic women and 661 primiparous, normotensive women. Analyses were adjusted for age, prepregnancy cigarette smoking, and education. RESULTS: Preeclamptic white women were more likely than normotensive white women to carry the up-regulating tumor necrosis factor-alpha-308 A/A (odds ratio, 4.1; 95% CI, 1.1-15.3) genotype. Both black and white women with preeclampsia were more likely than normotensive control subjects to carry the interleukin-1alpha-producing-4845 G/G genotype (black odds ratio, 11.6; 95% CI, 1.5-89.3; white odds ratio, 1.7; 95% CI, 0.7-3.9), -889 C/C genotype (black odds ratio, 5.1; 95% CI, 0.6-41.6; white odds ratio, 1.9; 95% CI, 0.8-4.7), and the interleukin-1alpha-4845/interleukin-1alpha-889/interleukin-1beta-3957 GCC/GCC haplotype (black odds ratio, 3.4; 95% CI, 1.3-8.7; white odds ratio, 2.1; 95% CI, 1.4-3.2). CONCLUSION: Cytokine genotypes were associated with preeclampsia and may identify women who are at high risk for preeclampsia.

Predictors of chronic pelvic pain in an urban population of women with symptoms and signs of pelvic inflammatory disease.

OBJECTIVE: The objective of this study was to assess the risk profile for chronic pelvic pain (CPP) after pelvic inflammatory disease (PID). STUDY: Multivariate logistic regression was used to assess risk factors for CPP in a longitudinal study of 780 predominately black, urban women with clinically suspected PID: complaints of acute pain (<30 days); a clinical finding of pelvic tenderness; and leukorrhea, mucopurulent cervicitis, or untreated gonococcal or chlamydial cervicitis. CPP was defined as pain reported at >or=2 consecutive interviews conducted every 3 to 4 months for 2 to 5 years. RESULTS: Nonblack race (odds ratio [OR], 2.17; 95% confidence interval [CI], 1.31-3.58), being married (OR, 2.06; 95% CI, 1.02-4.18), a low SF-36 mental health composite score (OR, 2.71; 95% CI, 1.69-4.34), >or=2 prior PID episodes (OR, 2.84; 95% CI, 1.07-7.54), and smoking (OR, 1.65; 95% CI, 1.01-2.71) independently predicted CPP. Histologic endometritis or evidence of endometrial Neisseria gonorrhoeae or Chlamydia trachomatis infection was negatively associated with CPP (OR, 0.69; 95% CI, 0.44-1.10). CONCLUSIONS: A range of demographic, clinical, historical, and behavioral factors predict CPP after PID.

Estrogen replacement, muscle composition, and physical function: The Health ABC Study.

PURPOSE: Although the beneficial effects of estrogen use on cardiovascular and cognitive function in postmenopausal women have been recently discredited, controversy remains regarding its usefulness for maintaining skeletal muscle mass or strength. Therefore, the purpose of this study was to determine whether estrogen use is associated with enhanced muscle composition and, if so, whether this translates into improved strength and physical function. METHODS: Cross-sectional analysis of 840 well-functioning community-dwelling white women (current estrogen replacement therapy (ERT) users = 259, nonusers = 581) aged 70-79 yr participating in the Health, Aging and Body Composition Study. Muscle composition of the midthigh by computed tomography included cross-sectional area (CSA) of the quadriceps, hamstrings, intermuscular fat and subcutaneous fat, and muscle attenuation in Hounsfield units (HU) as a measure of muscle density. Isometric hand grip and isokinetic knee extensor strength were assessed by dynamometry. Physical function was assessed using a summary scale that included usual 6-m walk and narrow walk speed, repeated chair stands, and standing balance. RESULTS: In analyses of covariance adjusted for relevant confounders, quadriceps muscle CSA and HU were greater in current ERT than non-ERT women (P < 0.05). Grip strength was also greater (P < 0.05) in women taking ERT while knee extensor strength approached significance (P < 0.10). However, differences in muscle composition and strength were modest at < or =3.3%. There was no difference by ERT status for the hamstring muscles, fat CSA, or for physical function. CONCLUSION: The associations between ERT and muscle composition and strength were minor and did not translate into improved physical function. Initiation of ERT for preservation of muscle composition and function may not be indicated.

Differential distribution of allelic variants in cytokine genes among African Americans and White Americans.

Racial disparities in health are largely unexplained. Because many diseases causing premature mortality among African Americans are mediated by the immune system, the authors explored the race-specific distribution of allelic variants in cytokine genes known to stimulate inflammation. The authors studied women seeking prenatal care and delivering singletons in uncomplicated first births at a US hospital in 1997-2001. A total of 179 African-American women and 396 White women were evaluated for functionally relevant allelic variants in cytokine genes. African-American women were significantly more likely to carry allelic variants known to up-regulate proinflammatory cytokines; odds ratios increased with allele dose. Odds ratios for African Americans versus Whites in genotypes up-regulating proinflammatory interleukin (IL) 1 (IL1A-4845G/G, IL1A-889T/T, IL1B-3957C/C, and IL1B-511A/A) ranged from 2.1 to 4.9. The proinflammatory cytokine interleukin-6 IL6-174 G/G genotype was 36.5 times (95% confidence interval (CI): 8.8, 151.9) more common among African Americans. Genotypes known to down-regulate the antiinflammatory interleukin-10 (IL10-819 T/T and IL10-1082 A/A) were elevated 3.5-fold (95% CI: 1.8, 6.6) and 2.8-fold (95% CI: 1.6, 4.9) in African Americans. Cytokine genotypes found to be more common in African-American women were consistently those that up-regulate inflammation.

Bacterial vaginosis and anaerobic bacteria are associated with endometritis.

BACKGROUND: Chlamydia trachomatis and/or Neisseria gonorrhoeae account for approximately one-third to one-half of pelvic inflammatory disease (PID) cases. Thus, up to 70% of cases have an unknown, nongonococcal/nonchlamydial microbial etiology. METHODS: We investigated the associations of N. gonorrhoeae, C. trachomatis, bacterial vaginosis, anaerobic bacteria, facultative bacteria, and lactobacilli with endometritis among 278 women with complete endometrial histology and culture from the PID Evaluation and Clinical Health Study. RESULTS: Women with acute endometritis were less likely to have H(2)O(2)-producing Lactobacillus species (odds ratio [OR], 0.1; 95% confidence interval [CI], 0.01-0.8) and more likely to be infected with C. trachomatis (OR, 16.2; 95% CI, 4.6-56.6), N. gonorrhoeae (OR, 11.6; 95% CI, 4.5-29.9), diphtheroids (OR, 5.0; 95% CI, 2.1-12.2), black-pigmented gram-negative rods (OR, 3.1; 95% CI, 1.4-7.0), and anaerobic gram-positive cocci (OR, 2.1; 95% CI, 1.0-4.3) and to have bacterial vaginosis (OR, 2.4; 95% CI, 1.3-4.3). CONCLUSIONS: We conclude that bacterial vaginosis-associated organisms are frequent among women with PID. Because these organisms were strongly associated with endometritis, we recommend that all women with PID be treated with regimens that include metronidazole.

Sleep and sleep-disordered breathing in adults with predominantly mild obstructive airway disease.

Neither the association between obstructive airways disease (OAD) and sleep apnea-hypopnea (SAH) nor the sleep consequences of each disorder alone and together have been characterized in an adult community setting. Our primary aims were (1) to determine if there is an association between OAD and SAH and (2) identify predictors of oxyhemoglobin desaturation during sleep in persons having OAD with and without SAH. Polysomnography and spirometry results from 5,954 participants in the Sleep Heart Health Study were analyzed. OAD was defined by a FEV1/FVC value less than 70%. Assessment of SAH prevalence in OAD was performed using thresholds of respiratory disturbance index (RDI) greater than 10 and greater than 15. A total of 1,132 participants had OAD that was predominantly mild (FEV1/FVC 63.81 +/- 6.56%, mean +/- SD). SAH was not more prevalent in participants with OAD than in those without OAD (22.32 versus 28.86%, with and without OAD, respectively, at RDI threshold values greater than 10; and 13.97 versus 18.63%, with and without OAD, respectively, at RDI threshold value greater than 15). In the absence of SAH, the adjusted odds ratio for sleep desaturation (> 5% total sleep time with saturation < 90%) was greater than 1.9 when FEV1/FVC was less than 65%. Participants with both OAD and SAH had greater sleep perturbation and desaturation than those with one disorder. Generally mild OAD alone was associated with minimally altered sleep quality. We conclude that (1) there is no association between generally mild OAD and SAH; (2) exclusive of SAH and after adjusting for demographic factors and awake oxyhemoglobin saturation, an FEV1/FVC value less than 65% is associated with increased risk of sleep desaturation; (3) desaturation is greater in persons with both OAD and SAH compared with each of these alone; and (4) individuals with generally mild OAD and without SAH in the community have minimally perturbed sleep.

Lower quality of life among women with chronic pelvic pain after pelvic inflammatory disease.

OBJECTIVE: To evaluate the morbidity from chronic pelvic pain after pelvic inflammatory disease (PID). METHODS: A total of 547 women were studied as part of the PID Evaluation and Clinical Health (PEACH) Study. Chronic pelvic pain was defined as pelvic pain reported at two or more consecutive interviews conducted every 3 to 4 months through 32 months and was graded as mild to moderate (low pain intensity) or moderate to severe (high pain intensity). Mean Medical Outcomes Study Short Form (SF-36) scores at 32 months were compared by chronic pelvic pain categories. RESULTS: The mean (+/- standard deviation) physical health composite scores and mental health composite scores from the SF-36 were progressively lower among women with increasing grade of chronic pelvic pain (physical health composite scores: no chronic pelvic pain = 87.3 +/- 10.7, mild to moderate chronic pelvic pain = 79.1 +/- 14.6, moderate to severe chronic pelvic pain = 73.6 +/- 16.0, P < .01; mental health composite scores: no chronic pelvic pain = 78.7 +/- 13.6, mild to moderate chronic pelvic pain = 69.1 +/- 15.8, moderate to severe chronic pelvic pain = 67.5 +/- 17.1, P < or = .01). Individual physical function, bodily pain, general health, vitality, social function, and mental health scores were also significantly lower among women with chronic pelvic pain and by increasing grade of pain intensity. CONCLUSION: Chronic pelvic pain after PID is associated with reduced physical and mental health.

The impact of estrogen and progesterone on asthma.

OBJECTIVE: This paper describes evidence of a positive effect of both endogenous and exogenous estrogen and progesterone on lung function across the life span in women. DATA SOURCES: Articles were identified using the keywords asthma, pulmonary function, menarche, menopause, estrogen, progesterone, hormone replacement therapy, oral contraceptives, and menstrual cycle from years 1966 to 2001 in MEDLINE. Additional studies were identified from article reference lists. STUDY SELECTION: Relevant, peer-reviewed original research articles in the English language were selected. RESULTS: Estrogen and/or progesterone may alter pulmonary function and asthma. Premenopausal women experience decreases in pulmonary function and increases in asthma exacerbations and hospitalizations during the premenstrual and menstrual phases. Oral contraceptives and hormone replacement therapy are associated with improved pulmonary function and decrease in asthma exacerbation. Some asthmatic patients experience improved pulmonary function and reduced asthma medication requirement during pregnancy. CONCLUSIONS: Estrogen and progesterone modify airway responsiveness. Further research is needed to elucidate the clinical relevance of estrogen and progesterone in the pathophysiology and therapy of asthma.

Strength and muscle quality in a well-functioning cohort of older adults: the Health, Aging and Body Composition Study.

OBJECTIVES: To determine whether lower lean mass and higher fat mass have independent effects on the loss of strength and muscle quality in older adults and might explain part of the effect of age. DESIGN: Single-episode, cross-sectional analyses of a cohort of subjects in the Health, Aging and Body Composition (Health ABC) Study. SETTING: Ambulatory clinic and research laboratory. PARTICIPANTS: Two thousand six hundred twenty-three men and women aged 70 to 79 from the Health ABC Study. MEASUREMENTS: Upper and lower extremity strength was measured using isokinetic (knee extension) and isometric (grip strength) dynamometers. Body composition (lean mass and fat mass) was determined by measuring lean mass of upper and lower extremities and the total body by dual-energy x-ray absorptiometry. Muscle quality was ascertained by taking the ratio of strength to muscle mass for both upper and lower extremities. RESULTS: Upper and lower extremity strength and muscle quality decreased as age increased. Most of the explained variance in strength was due to differences in muscle mass, but, in those at the extremes of body fat and lower leg muscle quality, the association with body fat was independent of the effect of age. Although blacks had greater muscle strength and mass than whites, leg muscle quality tended to be lower in blacks than in whites. Upper extremity strength adjusted for lean mass and muscle quality were also associated inversely and independently with age, body fat, and black race. CONCLUSION: In this older cohort, lower strength with older age was predominantly due to a lower muscle mass. Age and body fat also had significant inverse associations with strength and muscle quality. Both preservation of lean mass and prevention of gain in fat may be important in maintaining strength and muscle quality in old age.

Endometritis does not predict reproductive morbidity after pelvic inflammatory disease.

OBJECTIVE: We investigated the association between endometritis and reproductive morbidity. STUDY DESIGN: Participants were 614 women in the PID Evaluation and Clinical Health (PEACH) Study with pelvic pain, pelvic organ tenderness, and leukorrhea, mucopurulent cervicitis, or untreated cervicitis. We compared women with endometritis (>or=5 neutrophils or >or=2 plasma cells), Neisseria gonorrhoeae or Chlamydia trachomatis upper genital tract infection (UGTI) or both to women without endometritis/UGTI for outcomes of pregnancy, infertility, recurrent pelvic inflammatory disease (PID), and chronic pelvic pain (CPP), adjusting for age, race, education, PID history, and baseline infertility. RESULTS: Endometritis/UGTI was not associated with reduced pregnancy (odds ratio [OR] 0.8, 95% CI 0.6-1.2) or elevated infertility (OR 1.0, 95% CI 0.6-1.6), recurrent PID (OR 0.6, 95% CI 0.4-0.9), or CPP (OR 0.6, 95% CI 0.4-0.9). PEACH participants with and without endometritis/UGTI had higher age- and race-specific pregnancy rates than 1997 national rates. CONCLUSION: Among women with clinically suspected mild-to-moderate PID treated with standard antibiotics, endometritis/UGTI was not associated with reproductive morbidity.

Walking performance and cardiovascular response: associations with age and morbidity--the Health, Aging and Body Composition Study.

BACKGROUND: The long-distance corridor walk is a timed 400-meter walk test used to assess walking endurance in well-functioning men and women aged 70-79 in the Health, Aging and Body Composition Study. METHODS: We examined walking time along with heart rate and blood pressure response in relationship to prevalent chronic conditions, weight, physical activity, and markers of subclinical disease. Of 3075 participants, 2324 (76%) completed the test with heart rate and blood pressure responses in the range expected for a moderate level of exertion. RESULTS: Slower walking time was influenced by both clinical and subclinical disease, and also was strongly related to both low and high body weight and low self-reported physical activity. Heart rate and blood pressure responses were higher with several clinical and subclinical diseases, but heart rate response and recovery were more strongly related to walking time than to disease. Higher body mass index and lower physical activity were associated with greater heart rate response and recovery. CONCLUSIONS: The independent contribution of both clinical and subclinical disease to walking time supports the use of walking tests as a summary measure of disease in older adults. The independent association of walking time with physical activity suggests that it is sensitive to levels of fitness as well. Together these findings show that walking performance is a valid indicator of physiologic reserve in older adults.

How does low back pain impact physical function in independent, well-functioning older adults? Evidence from the Health ABC Cohort and implications for the future.

OBJECTIVE: To determine the relationships between low back pain (LBP) frequency and intensity and self-reported and performance-based physical function in a large cohort of well-functioning older adults. DESIGN: Cross-sectional survey and examination. SETTING: Community-based cohort of the Health, Aging, and Body Composition (Health ABC) study. PARTICIPANTS: Participants were 2,766 community-dwelling adults, aged 70-79; 42% were African American, 52% were men. OUTCOME MEASURES: 1) Back pain-location, frequency, intensity; 2) Hip and/or knee pain; 3) Body mass index (BMI); 4) Self-reported difficulty doing functional tasks; 5) Lower extremity function, using the battery from the Established Populations for Epidemiologic Studies in the Elderly (EPESE); 6) Self-rated health; 7) Comorbidity; 8) Depressive symptoms, using the Center for Epidemiological Studies-Depression (CES-D) scale. RESULTS: LBP was common (36%), and its frequency/intensity was significantly associated with other pain and comorbidities. In gender-specific models, LBP frequency/intensity was not significantly associated with EPESE performance score after adjusting for age, race, BMI, CES-D score, knee pain, hip pain, and other comorbidities. LBP frequency/intensity, however, was significantly associated with self-reported difficulty with most functional tasks after adjusting for important confounders. CONCLUSIONS: Among well-functioning community-dwelling older adults, LBP frequency/intensity was associated with perceived difficulty in performing important functional tasks, but not with observed physical performance. The demonstrated dose-response relationship between pain frequency/intensity and self-reported task performance difficulty underscores the importance of clinical efforts to treat pain without necessarily eradicating it. Additional work is needed to determine whether back pain is associated with a risk for progressive functional decline and loss of independence in older adults and whether therapeutic interventions can ameliorate decline and, therefore, preserve independence.
