RESUMO

BACKGROUND: We analyzed the association between substance use (SU) and condomless sex (CS) among HIV-negative adults reporting heterosexual sex in the Seek, Test, Treat, and Retain (STTR) consortium. We describe the impact of SU as well as person/partner and context-related factors on CS, identifying combinations of factors that indicate the highest likelihood of CS. METHODS: We analyzed data from four US-based STTR studies to examine the effect of SU on CS using two SU exposures: 1) recent SU (within 3 months) and 2) SU before/during sex. Behavioral data were collected via 1:1 or self-administered computerized interviews. Adjusted individual-study, multivariable relative risk regression was used to examine the relationship between CS and SU. We also examined interactions with type of sex and partner HIV status. Pooled effect estimates were calculated using traditional fixed-effects meta-analysis. We analyzed data for recent SU (n = 6781; 82% men, median age = 33 years) and SU before/during sex (n = 2915; 69% men, median age = 40 years). RESULTS: For both exposure classifications, any SU other than cannabis increased the likelihood of CS relative to non-SU (8-16%, p-values< 0.001). In the recent SU group, however, polysubstance use did not increase the likelihood of CS compared to single-substance use. Cannabis use did not increase the likelihood of CS, regardless of frequency of use. Type of sex was associated with CS; those reporting vaginal and anal sex had a higher likelihood of CS compared to vaginal sex only for both exposure classifications (18-21%, p < 0.001). Recent SU increased likelihood of CS among those reporting vaginal sex only (9-10%, p < 0.001); results were similar for those reporting vaginal and anal sex (5-8%, p < 0.01). SU before/during sex increased the likelihood of CS among those reporting vaginal sex only (20%; p < 0.001) and among those reporting vaginal and anal sex (7%; p = 0.002). Single- and poly-SU before/during sex increased the likelihood of CS for those with exclusively HIV-negative partners (7-8%, p ≤ 0.02), and for those reporting HIV-negative and HIV-status unknown partners (9-13%, p ≤ 0.03). CONCLUSION: Except for cannabis, any SU increased the likelihood of CS. CS was associated with having perceived HIV-negative partners and with having had both anal/vaginal sex.

RESUMO

BACKGROUND: Prevention of rectal HIV transmission is a high-priority goal for vaccines and topical microbicides because a large fraction of HIV transmissions occurs rectally. Yet, little is known about the specific target-cell milieu in the human rectum other than inferences made from the colon. METHODS: We conducted a comprehensive comparative in situ fluorescence study of HIV target cells (CCR5-expressing T cells, macrophages, and putative dendritic cells) at 4 and 30 cm proximal of the anal canal in 29 healthy individuals, using computerized analysis of digitized combination stains. RESULTS: Most strikingly, we find that more than 3 times as many CD68 macrophages express the HIV coreceptor CCR5 in the rectum than in the colon (P = 0.0001), and as such rectal macrophages seem biologically closer to the HIV-susceptible CCR5 phenotype in the vagina than the mostly HIV-resistant CCR5 phenotype in the colon. Putative CD209 dendritic cells are generally enriched in the colon compared with the rectum (P = 0.0004), though their CCR5 expression levels are similar in both compartments. CD3 T-cell densities and CCR5 expression levels are comparable in the colon and rectum. CONCLUSIONS: Our study establishes the target-cell environment for HIV infection in the human distal gut and demonstrates in general terms that the colon and rectum are immunologically distinct anatomical compartments. Greater expression of CCR5 on rectal macrophages suggests that the most distal sections of the gut may be especially vulnerable to HIV infection. Our findings also emphasize that caution should be exercised when extrapolating data obtained from colon tissues to the rectum.

RESUMO

A 37-year-old man with known intravenous drug abuse presented in the surgical ambulatory care unit with acute leg ischemia after accidental intra-arterial injection of dissolved flunitrazepam tablets into the right femoral artery. A combination of anticoagulation, vasodilatation, and local selective and superselective thrombolysis with urokinase was performed to salvage the leg. As a result of the severe ischemia-induced pain, the patient had to be monitored over the complete therapy period on the intensive care unit with permanent administration of intravenous fluid and analgetics. We describe the presenting symptoms and the interventional technique, and we discuss the recent literature regarding the management of accidental intra-arterial injection of dissolved flunitrazepam tablets.

RESUMO

BACKGROUND: The Step study was a randomized trial to determine whether an adenovirus type 5 (Ad5) vector vaccine, which elicits T cell immunity, can lead to control of human immunodeficiency virus (HIV) replication in participants who became HIV-infected after vaccination. METHODS: We evaluated the effect of the vaccine on trends in HIV viral load, CD4+ T cell counts, time to initiation of antiretroviral therapy (ART), and AIDS-free survival in 87 male participants who became infected with HIV during the Step study and who had a median of 24 months of post-infection follow-up. RESULTS: There was no overall effect of vaccine on mean log(10) viral load (estimated difference between groups, -0.11; P = .47). In a subset of subjects with protective HLA types (B27, B57, B58), mean HIV-1 RNA level over time was lower among vaccine recipients. There was no significant difference in CD4+ T cell counts, time to ART initiation, or in AIDS-free survival between HIV-1-infected subjects who received vaccine versus those who received placebo. CONCLUSIONS: HIV RNA levels, CD4+ T cell counts, time to initiation of ART, and AIDS-free survival were similar in vaccine and placebo recipients. There may have been a favorable effect of vaccine on HIV-1 RNA levels in participants with HLA types associated with better control of HIV-1.

RESUMO

BACKGROUND: In the continuing effort to introduce antiretroviral therapy in resource-limited settings, there is a need to understand differences between natural history of HIV in different populations and to identify feasible clinical measures predictive of survival. METHODS: We examined predictors of survival among 836 heterosexuals who were infected with HIV subtype CRF01_AE in Thailand. RESULTS: From 1993 to 1999, 269 (49.4%) men and 65 (25.7%) women died. The median time from the estimated seroconversion to death was 7.8 years (95% confidence interval 7.0-9.1). Men and women with enrolment CD4 counts <200 cells/microl had about 2 and 11 times greater risk of death than those with CD4 counts of 200-500 and >500, respectively. Measurements available in resource-limited settings, including total lymphocyte count (TLC), anaemia, and low body mass index (BMI), also predicted survival. Men with two or more of these predictors had a median survival of 0.8 (0.5-1.8) years, compared with 2.7 (1.9-3.3) years for one predictor and 4.9 (4.1-5.2) years for no predictors. CONCLUSIONS: The time from HIV infection to death appears shorter among this Thai population than among antiretroviral naive Western populations. CD4 count and viral load (VL) were strong, independent predictors of survival. When CD4 count and VL are unavailable, individuals at high risk for shortened HIV survival may be identified by a combination of low TLC, anaemia, and low BMI. This combination of accessible clinical measures of the disease stage may be useful for medical management in resource-limited settings.

RESUMO

This study evaluated Amsel's criteria, the FemExam card and pH plus amine methods for the diagnosis of bacterial vaginosis (BV) in a resource-poor setting. Two hundred Azerbaijani women participated in a study about reproductive health that included a gynaecological examination and an interviewer-administered survey. Using the WHO syndromic diagnosis algorithm, nearly all women (99%) had abnormal vaginal discharge. The prevalence of BV by Gram stain was 35%; using pH plus amine, the FemExam card and Amsel's criteria, prevalence ranged from 29% to 49%. No behavioural or demographic characteristics were associated with BV as diagnosed by Gram stain. The sensitivity ranged from 0.59 to 0.74 and specificity from 0.65 to 0.92 using the three methods. The pH plus amine test is better than syndromic management protocols, and although it is not the most sensitive or specific of the three methods it will be easiest to implement in resource-poor settings.

RESUMO

Toxic epidermal necrolysis (TEN) is an epidermolytic skin disorder associated with drug administration. It is associated with an erythematous rash with full thickness epidermal loss and characteristic histology. A 35-year-old woman underwent allogeneic hematopoietic stem cell transplantation (HSCT) for severe aplastic anemia (SAA). She developed an acute epidermolytic rash and TEN was diagnosed on the basis of skin biopsy. In the HSCT setting, TEN should be thought of as an important differential diagnosis of epidermolytic dermopathies. The most distinctive diagnostic test in the differential diagnosis of these disorders is skin biopsy

RESUMO

OBJECTIVE: To determine the natural history of bacterial vaginosis in women with or at risk for human immunodeficiency virus (HIV). METHODS: A cohort of 854 HIV-infected women and 434 HIV-uninfected women from four US sites was followed prospectively with gynecologic exams every 6 months over a 5-year period. The prevalence, incidence, persistence, and severity of bacterial vaginosis, which was defined using a Gram-staining scoring system, were calculated using generalized estimating equation methods. RESULTS: In adjusted analyses, HIV-infected women had a higher prevalence of bacterial vaginosis than HIV-uninfected women (adjusted odds ratio [OR] 1.29; 95% confidence interval [CI] 1.08, 1.55). Although HIV-infected women were not more likely to have incident infections, they were more likely to have persistence of their infections (adjusted OR 1.49; 95% CI 1.18, 1.89). Similarly, immunocompromised women (CD4+ cell count less than 200 cells/microL) were more likely than HIV-infected women with higher CD4+ cell counts (more than 500 cells/microL) to have prevalent (adjusted OR 1.29; 95% CI 1.03, 1.60) and persistent (adjusted OR 1.38; 95% CI 1.01, 1.91) bacterial vaginosis infections, but not more likely to have incident infections. Immunocompromised women had more severe bacterial vaginosis by both clinical criteria (adjusted OR 1.40; 95% CI 1.08, 1.82) and by Gram-staining criteria (adjusted OR 1.50; 95% CI 1.12, 2.00). CONCLUSIONS: Bacterial vaginosis is more prevalent and persistent among HIV-infected women, particularly among those who are immunocompromised. Immunocompromised women are more likely than HIV-infected women with higher CD4+ cell counts to have severe bacterial vaginosis.

RESUMO

BACKGROUND: Bacterial vaginosis is a common gynecologic infection that has been associated with a variety of gynecologic and obstetric complications, including pelvic inflammatory disease, postabortal infection and premature delivery. Recent studies suggest that bacterial vaginosis may increase a woman's risk for human immunodeficiency virus (HIV). We undertook this study to assess whether the prevalence and characteristics of bacterial vaginosis differed according to HIV status in high-risk US women. METHODS: Prevalence of bacterial vaginosis was assessed by Gram's stain and clinical criteria for 854 HIV-infected and 434 HIV-uninfected women enrolled in the HIV Epidemiology Research (HER) Study. Multiple logistic regression techniques were used to determine whether HIV infection independently predicted bacterial vaginosis. RESULTS: Almost half (46%) the women had bacterial vaginosis by Gram's stain. The prevalence of bacterial vaginosis was 47% in the HIV-positive women compared with 44% in the HIV-negative women; this difference was not statistically significant (p = 0.36). After adjustment for other covariates, HIV-positive women were more likely than HIV-negative women to have bacterial vaginosis (odds ratio (OR) 1.31; 95% confidence interval (CI) 1.01-1.70) by Gram's stain but not by clinical criteria (OR 1.16; CI 0.87-1.55). Among HIV-positive women, use of antiretroviral drugs was associated with a lower prevalence of bacterial vaginosis (adjusted OR 0.54; Cl 0.38-0.77). CONCLUSIONS: In this cross-sectional analysis of high-risk US women, HIV infection was positively correlated with bacterial vaginosis diagnosed by Gram's stain.

RESUMO

Human immunodeficiency virus (HIV) infection and related immunosuppression are associated with excess risk for cervical neoplasia and human papillomavirus (HPV) persistence. Type-specific HPV infection was assessed at 6-month intervals for HIV-positive and HIV-negative women (median follow-up, 2.5 and 2.9 years, respectively). The type-specific incidence of HPV infection was determined, and risk factors for HPV persistence were investigated by statistical methods that accounted for repeated measurements. HIV-positive women were 1.8, 2.1, and 2.7 times more likely to have high-, intermediate-, and low-risk HPV infections, respectively, compared with HIV-negative women. In multivariate analysis, high viral signal, but not viral risk category, was independently associated with persistence among HIV-positive subjects (odds ratio [OR], 2.5; 95% confidence interval [CI], 2.1-2.9). Furthermore, persistence was 1.9 (95% CI, 1.5-2.3) times greater if the subject had a CD4 cell count <200 cells/microL (vs. >500 cells/microL). Thus, HIV infection and immunosuppression play an important role in modulating the natural history of HPV infection.

RESUMO

OBJECTIVE: Correlates of abnormal human immunodeficiency virus cervical cytologic findings were examined among women infected with human immunodeficiency virus and uninfected women. STUDY DESIGN: We performed a cross-sectional analysis of baseline data on demographically similar women with infection or risk factors for it. RESULTS: Among 1050 women without hysterectomy, squamous intraepithelial lesions were more common among women infected with human immunodeficiency virus than among uninfected women (18.8% vs 5.3%; P <.001). In multivariate analysis the association of squamous intraepithelial lesions with human papillomavirus infection was strong; adjusted prevalence ratios were 27 for high-risk, 25 for intermediate-risk, and 10 for low-risk types (95% confidence intervals, 12-58, 12-54, and 4-25, respectively). Much lower adjusted prevalence ratios were seen for the only other factor significantly associated with squamous intraepithelial lesions, namely, infection with human immunodeficiency virus in conjunction with a reduced CD4(+) cell count. Adjusted prevalence ratios were 1.9 for CD4(+) cell counts <200 and 1.6 for CD4(+) cell counts between 200 and 500 (95% confidence intervals, 1.2-3.0 and 1.0-2.5, respectively). Adjusted attributable fractions calculated for this study population indicated that if both human immunodeficiency virus and human papillomavirus were removed, 47.6% of the observed lesions with atypical squamous cells of uncertain significance and 93.4% of the observed squamous intraepithelial lesions would be prevented. CONCLUSION: Squamous intraepithelial lesions are more common among human immunodeficiency virus-infected women and are associated most commonly with high- and intermediate-risk human papillomavirus types and secondarily with human immunodeficiency virus-associated immune compromise.

RESUMO

Antifungal agents can effectively treat mucosal candidiasis; however, their use can lead to colonization with less susceptible species and to resistance among normally susceptible strains. Oral and vaginal Candida isolates obtained at 3 points over 2 years from human immunodeficiency virus (HIV)-seropositive and at-risk HIV-seronegative women were identified by species and were evaluated for in vitro fluconazole susceptibility. Prevalence of non-C. albicans strains increased over time, and these strains were more likely among women reporting current antifungal use. Among C. albicans isolates, resistance was rare, with no evidence for progressive reduction in susceptibility over time. Among non-C. albicans isolates, reduced susceptibility occurred frequently and increased with time. HIV-seropositive women were more likely to have non-C. albicans isolates with reduced susceptibility as were women reporting current antifungal use. This evolution and section of mucosa-colonizing Candida species with reduced susceptibility could play a critical early role in the development of antifungal resistance among C. albicans isolates responsible for refractory candidiasis.

RESUMO

OBJECTIVE: To estimate the risk of intraoperative or postoperative complications for interval laparoscopic tubal sterilizations. METHODS: We used a prospective, multicenter cohort study of 9475 women who had interval laparoscopic tubal sterilization to calculate the rates of intraoperative or postoperative complications. The relative safety of various methods was assessed by calculating overall complication rates for each major method of tubal occlusion. Method-related complication rates also were calculated and included only complications attributable to a method of occlusion. We used logistic regression to identify independent predictors of one or more complications. RESULTS: When we used a more restrictive definition of unintended major surgery, the overall rate of complications went from 1.6 to 0.9 per 100 procedures. There was one life-threatening event and there were no deaths. Complications rates for each of the four major methods of tubal occlusion ranged from 1.17 to 1.95, with no significant differences between them. When complication rates were calculated, the spring clip method had the lowest method-related complication rate (0.47 per 100 procedures), although it was not significantly different from the others. In adjusted analysis, diabetes mellitus (adjusted odds ratio [OR] 4.5; 95% confidence interval [CI] 2.3, 8.8), general anesthesia (OR 3.2; CI 1.6, 6.6), previous abdominal or pelvic surgery (OR 2.0; CI 1.4, 2.9), and obesity (OR 1.7; CI 1.2, 2.6) were independent predictors of one or more complications. CONCLUSION: Interval laparoscopic sterilization generally is a safe procedure; serious morbidity is rare.

RESUMO

The aim of this study was to identify factors ascertainable at initial presentation that predict a complicated clinical course in HIV-negative women hospitalized with pelvic inflammatory disease (PID). We used data from a cross-sectional study of women admitted for clinically diagnosed PID to a public hospital in New York City. A complicated clinical course was defined as undergoing surgery, being readmitted for PID, or having a prolonged hospital stay (> or = 14 days) but no surgery. Logistic regression was used to identify independent predictors of complications. In adjusted analyses, older age (> or = 35 years) was a risk factor for prolonged hospital stay (adjusted odds ratio [OR] = 3.9; 95% confidence interval [CI] = 1.3-11.6) and surgery (OR = 10.4; CI = 2.5-44.1); self-reported drug use was a risk factor for readmission for PID (OR = 7.7; CI = 1.4-41.1) and surgery (OR = 6.2; CI = 1.8-20.5). Older age and self-reported drug use appear to be independent risk factors for a complicated clinical course among women hospitalized with PID.

RESUMO

CONTEXT: Little is known about pregnancy outcomes among the approximately 11 million refugees worldwide, 25% of whom are women of reproductive age. OBJECTIVE: To estimate incidence of and determine risk factors for poor pregnancy outcomes and to calculate the contribution of mortality from neonatal and maternal deaths to overall mortality in a refugee camp. DESIGN: Cross-sectional review of records and survey, conducted in February and March 1998. SETTING: Mtendeli refugee camp, Tanzania. PARTICIPANTS: For the overall assessment, 664 Burundi women who had a pregnancy outcome during a recent 5-month period (September 1, 1997-January 31, 1998) and their 679 infants; 538 women (81%) completed the survey. MAIN OUTCOME MEASURES: Incidence of fetal death (fetus born > or =500 g or > or =22 weeks' gestation with no signs of life), low birth weight (<2500 g), neonatal death (death <28 days of life), and maternal death (deaths during or within 42 days of pregnancy from any cause related to or aggravated by the pregnancy or its management). RESULTS: The fetal death rate was 45.6 per 1000 births, the neonatal mortality rate was 29.3 per 1000 live births, and 22.4% of all live births were low birth weight. Compared with women without poor pregnancy outcome, those with poor pregnancy outcome were more likely to report prior high socioeconomic status (adjusted odds ratio [OR], 1.6; 95% confidence interval [CI], 1.1-2.4), having a first or second pregnancy (OR, 2.2; 95% CI, 1.4-3.4), and having 3 or more episodes of malaria during pregnancy (OR, 2.0; 95% CI, 1.4-3.1). Neonatal and maternal deaths accounted for 16% of all deaths during the period studied. CONCLUSIONS: Poor pregnancy outcomes were common in this refugee setting, and neonatal and maternal deaths, 2 important components of reproductive health-related deaths, contributed substantially to overall mortality.

RESUMO

The heterosexual transmission of subtype E human immunodeficiency virus type 1 (HIV-1) infection was evaluated in 467 couples in Thailand in whom the man was HIV-1 positive and the woman had no risk factors for HIV other than sex with her infected partner. At baseline, 216 (46.3%) of the 467 women were positive for HIV-1; prevalence of HIV among women was 52.2% when their male partners had CD4+ lymphocyte counts of <200 cells/microL, 45.9% in women whose partners had counts of 200-499 micro/L, and 39.2% in women whose partners had counts of >/=500/microL. Women were twice as likely to be HIV positive if their partners had a history of a sexually transmitted disease (STD); however, their HIV prevalence was 29% among couples who had no STD history. It appears that female partners of men infected with subtype E HIV-1 are at high risk of infection even when the man's CD4+ cell count is relatively high. A high rate of STDs may contribute significantly to this risk [corrected].

RESUMO

Women who were partners of HIV-positive blood donors were enrolled in a study of heterosexual HIV transmission between March 1992 and December 1996 and were interviewed and examined. Gynaecological conditions, including cervical dysplasia, human papillomavirus (HPV) infection, gonorrhoea, chlamydial infection, trichomoniasis, bacterial vaginosis, vaginal candidiasis and syphilis were assessed in addition to HIV status and CD4 level. Of 481 women enrolled, 224 (46.6%) were HIV seropositive. HIV-infected women were more likely to have abnormal vaginal discharge on physical examination (OR=2.6, P <0.01), HPV infection with a high-risk type (OR=6.9, P <0.01), and cervical dysplasia (OR=5.3, P <0.01). The prevalence of other gynaecological conditions detected at the enrolment visit did not differ by HIV status. History of prior STD (OR=2.0, P <0.01) was more common among HIV-infected women. The median CD4 count was 400 cells/microl among HIV-infected women. The prevalence of abnormal vaginal discharge and bacterial vaginosis increased significantly with decreasing CD4 count. The prevalence of ectopy, vaginal candidiasis, and cervical dysplasia increased with decreasing CD4 count, but these trends were not significant. We conclude that HIV-infected Thai women appear to have increased prevalences of abnormal vaginal discharge, squamous intraepithelial lesions and self-reported history of STD.


PIP: Gynecologic conditions associated with HIV infection were examined in 481 regular female sex partners of HIV-positive male blood donors enrolled in a study of heterosexual HIV transmission conducted at Chiang Mai University Hospital and Lampang Provincial Hospital in Thailand in 1992-96. Of these women, 224 (46.6%) were HIV-infected. HIV-positive and HIV-negative women were similar in terms of age, education, and age at first intercourse; however, a history of sexually transmitted disease was more common among the HIV-infected women (31.7%) than their uninfected counterparts (18.7%). HIV-infected women also were significantly more likely to have abnormal gynecologic conditions, including abnormal vaginal discharge at physical examination (odds ratio (OR), 2.6; 95% confidence interval (CI), 1.6-4.2) and cervical dysplasia (OR, 5.3; 95% CI, 2.0-15.2). Among HIV-positive women, the prevalence of abnormal vaginal discharge and bacterial vaginosis increased significantly with decreasing CD4 count. Syphilis, gonorrhea, chlamydia, and trichomoniasis rates were generally low and did not differ by HIV status. These findings suggest a need for further research on variations in gynecologic conditions associated with HIV infection in different countries.
