Sexually transmitted infections (STIs) have shown to enhance the transmission of human immunodeficiency virus (HIV) and to be more common among female commercial sex workers (FSWs). A cross-sectional study was conducted among 625 FSWs in six cities of Argentina in 2000-2002. The seroprevalence of HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), human T-cell lymphotropic virus type I/II, and syphilis was 3.2%, 14.4%, 4.3%, 1.6%, and 45.7%, respectively. Syphilis was associated with older age (>/= 30 years, adjusted odds ratio [AOR] = 2.6 to 4.9), >/= 10 years in sex work (AOR = 2.2), use of illegal drugs (AOR = 2.1), and a prior history of an STI (AOR = 3.0). HBV and syphilis was the most common co-infection in 44 (7.5%) subjects. FSWs in Argentina are exposed to HIV and other STIs due to high-risk sexual and illegal drug use behavior. Renewed efforts are necessary to intervene effectively in this high-risk population. 相似文献

This study identifies the risk factors for hepatitis B virus (HBV) and hepatitis C virus (HCV) and measures the prevalence of hepatitis B surface antigen (HBsAg) and antibody to hepatitis C (anti-HCV) in the general population of Jakarta. A population-based sample of 985 people aged 15 and above was surveyed. Risk factors were identified through questionnaires and home visits. Serum was analysed for HBsAg, antibody to hepatitis B surface antigen (anti-HBs), anti-HCV, aspartate aminotransferase (AST) and alanine aminotransferase (ALT). The seroprevalence was: 4.0% (39/985) for HBsAg, 17.2% (170/985) for anti-HBs, and 3.9% (38/985) for anti-HCV. The risk factors for hepatitis B and hepatitis C infection had little in common. Low socioeconomic status was a strong risk factor for HBsAg (adjusted odds ratio (OR) 18.09; 95% confidence interval (CI) 2.35–139.50). In addition, the Chinese group has 2.97 higher risk of having HBV infection compared with the Malayan ethnic group (adjusted OR 2.97; 95% CI 1.22–7.83). There was moderate positive trend between family size and risk of HBsAg positivity (P= 0.130). Age over 50 (adjusted OR 14.72; 95% CI 4.35–49.89) and history of transfusion were significant risk factors for hepatitis C (adjusted OR 3.03; 95% CI 1.25–7.33). Hepatitis B and hepatitis C infections have different risk factors in Jakarta, a high risk in population for both diseases. Hepatitis B transmission is associated with low socioeconomic status, Chinese ethnic group and large family size, while hepatitis C is associated with an older age and a history of transfusions. 相似文献

Individuals using illicit drugs are at risk for heavy drinking and infection with human immunodeficiency virus (HIV) and/or hepatitis C virus (HCV). Despite medical consequences of drinking with HIV and/or HCV, whether drug users with these infections are less likely to drink is unclear. Using samples of drug users in treatment with lifetime injection use (n = 1309) and non-injection use (n = 1996) participating in a large, serial, cross-sectional study, we investigated the associations between HIV and HCV with abstinence from alcohol. About half of injection drug users (52.8 %) and 26.6 % of non-injection drug users abstained from alcohol. Among non-injection drug users, those with HIV were less likely to abstain [odds ratio (OR) 0.55; adjusted odds ratio (AOR) 0.58] while those with HCV were more likely to abstain (OR 1.46; AOR 1.34). In contrast, among injection drug users, neither HIV nor HCV was associated with drinking. However, exploratory analyses suggested that younger injection drug users with HIV or HCV were more likely to drink, whereas older injection drug users with HIV or HCV were more likely to abstain. In summary, individuals using drugs, especially non-injection users and those with HIV, are likely to drink. Age may modify the risk of drinking among injection drug users with HIV and HCV, a finding requiring replication. Alcohol intervention for HIV and HCV infected drug users is needed to prevent further harm. 相似文献

To assess the epidemiology of hepatitis B virus (HBV) infection among men who have sex with men (MSM) in Peru, we evaluated the prevalence and associated risk factors for HBV serologic markers among participants of a HIV sentinel surveillance conducted in 2002–2003. The standardized prevalences for total antibodies to hepatitis B core antigen (anti-HBc) and hepatitis B surface antigen (HBsAg) were 20.2% and 2.8%, respectively. Individuals with human immunodeficiency virus (HIV-1) infection had significantly higher anti-HBc (44.3% versus 19.3%) and HBsAg (9.5% versus 2.3%) prevalences than uninfected men. Increasing age (adjusted odds ratio [AOR] = 1.06), versatile sexual role (AOR = 1.59), sex in exchange for money/gifts (AOR = 1.58), syphilis (AOR = 1.74), HIV-1 infection (AOR = 1.64), and herpes simplex virus type 2 (HSV-2, AOR = 2.77) infection were independently associated with anti-HBc positivity, whereas only HIV-1 infection (AOR = 3.51) and generalized lymph node enlargement (AOR = 3.72) were associated with HBsAg positivity. Pre-existing HBV infection is very common among Peruvian MSM and was correlated with sexual risk factors. MSM in Peru constitute a target population for further HBV preventive and treatment interventions. 相似文献

A cross-sectional survey was conducted to determine the sociodemographic correlates of herpes simplex virus type 2 (HSV-2) infection among male and female commercial sex workers in Kunming, Yunnan Province of China. HSV-2 prevalence was 33.0%, human immunodeficiency virus (HIV) infection was 2.4% and hepatitis C virus (HCV) infection was 6.8%. Subjects who were positive for HSV-2 had a significantly higher prevalence of HIV infection (5.5% versus 0.9%, P = 0.002; odds ratio [OR]: 6.4, P = 0.006) and HCV infection (18.7% versus 2.4%, P < 0.001; OR: 7.6, P < 0.001) compared with HSV-2-negative individuals. Risk factors that increased the odds of HSV-2 infection were HIV infection, HCV infection, being female, and having a steady sex partner within the last six months (P < or = 0.01). In a multivariate analysis, being female (OR: 6.6, P < 0.001), having HCV infection (OR: 5.9, P < 0.001) and having a sex partner within the last six months (OR: 2.2, P < 0.05) showed greater odds of being infected with HSV-2. A strong relationship was found between HSV-2, HIV and HCV infections. 相似文献

Assisted injection among injection drug users (IDUs) remains understudied. We recruited 1,056 IDUs using respondent‐driven sampling in Tijuana, Mexico. Participants underwent HIV and syphilis testing and structured interviews. One‐quarter (25%) sought injection assistance in the past 6 months. Seeking injection assistance was independently associated with being female (adjusted odds ratio [AOR]= 2.59; 95% confidence interval [CI]= 1.73–3.90), being born outside Baja California (AOR = 1.75; CI = 1.26–2.42), having recent abscesses (AOR = 2.59; CI = 1.93–3.47), using syringes previously used by others in the past 6 months (AOR = 1.99; CI = 1.45–2.71), and ever being arrested for carrying sterile syringes (AOR = 1.55; CI = 1.15–2.09).

Hepatitis C in Peru: risk factors for infection, potential iatrogenic transmission, and genotype distribution. 总被引:2,自引:0,他引:2
J L Sanchez M H Sjogren J D Callahan D M Watts C Lucas M Abdel-Hamid N T Constantine K C Hyams S Hinostroza R Figueroa-Barrios J C Cuthie 《The American journal of tropical medicine and hygiene》2000,63(5-6):242-248
A large seroepidemiologic and genotyping study of hepatitis C virus (HCV) was conducted in Lima, Peru, during the periods of 1986 to 1993 (cohort A) and 1994 (cohort B). Anti-HCV seroprevalence rates were 15.6% (216 of 1,389) and 11.7% (168 of 1,438), respectively. Low rates were seen among volunteer blood donors (1.1% and 0.8%). Anti-HCV rates were much higher among patients undergoing hemodialysis (43.7% and 59.3%), hemophiliacs (60.0% and 83.3%), in those more than 39 years old (18.2% and 26.0%), in females (25.0% and 27.4%), and in less-educated persons (16.9%). Age- and gender-adjusted risk factors in cohort B included blood transfusion history (adjusted odds ratio [AOR] = 29.8), prior organ transplantation (AOR = 9.1) or a history of hepatitis (AOR = 4.9), previous hospitalization (AOR = 3.7), a history of intravenous drug use (AOR = 3.5), prior major surgery (AOR = 2.6), a history of acupuncture (AOR = 2.1), previous dental procedures (AOR = 1.2), and prior medical injections (AOR = 1.04). The most prevalent HCV genotype was type 1 (86%), followed by type 3 (10%) and type 2 (2%). Transmission through unsafe injection-related and medical/dental procedures appears to play an important role in HCV infection among Peruvians. 相似文献

We assessed associations of herpes simplex virus types 1 and 2 (HSV-1 and -2), cytomegalovirus (CMV), and human herpesvirus 8 (HHV-8) infection with subclinical coronary atherosclerosis in 291 HIV-infected men in the Multicenter AIDS Cohort Study. Coronary artery calcium (CAC) was measured by non-contrast coronary CT imaging. Markers for herpesviruses infection were measured in frozen specimens collected 10-12 years prior to case identification. Multivariable logistic regression models and ordinal logistic regression models were performed. HSV-2 seropositivity was associated with coronary atherosclerosis (adjusted odds ratio [AOR]=4.12, 95% confidence interval [CI]=1.58-10.85) after adjustment for age, race/ethnicity, cardiovascular risk factors, and HIV infection related factors. Infection with a greater number of herpesviruses was associated with elevated CAC levels (AOR=1.58, 95% CI=1.06-2.36). Our findings suggest HSV-2 may be a risk factor for subclinical coronary atherosclerosis in HIV-infected men. Infection with multiple herpesviruses may contribute to the increased burden of atherosclerosis. 相似文献

OBJECTIVES: To determine whether South African youths living in communities that had either of two youth human immunodeficiency virus (HIV) prevention interventions [(a) loveLife Youth Centre or (b) loveLife National Adolescent Friendly Clinic Initiative] would have a lower prevalence of HIV, sexually transmitted infections (STIs), and high risk sexual behaviours than communities without either of these interventions. METHODS: In 2002 the baseline survey of a quasi-experimental, community-based study was conducted in South Africa. In total 33 communities were included in three study arms (11 communities per study arm). The final sample included 8735 youths aged 15-24 years. All participants took part in a behavioural interview and were tested for HIV, gonorrhoea (Neisseria gonorrhoeae) and Chlamydia (Chlamydia trachomatis). RESULTS: HIV prevalence was 20.0% among females and 7.5% among males (OR 3.93 95% CI 2.51-6.15). There were no significant differences between study arms for HIV, NG or CT prevalence at baseline. In multiple regression analyses, HIV was significantly associated with NG infection (OR 1.96 95% CI 1.24-3.12) but not with CT infection. Youths who reported >1 lifetime partner were also significantly more likely to be infected with HIV (OR 1.98 95% CI 1.55-2.52), as were those who reported ever having engaged in transactional sex (OR 1.86 P = 0.02) or having had genital ulcers in the past 12 months (OR 1.71 P < or = 0.001). CONCLUSIONS: HIV prevention programmes must ensure that gender inequities that place young women at greater risk for HIV infection are urgently addressed and they must continue to emphasize the importance of reducing the number of sexual partners and STI treatment. 相似文献

Background In Vietnam, the prevalence of hepatitis C virus (HCV) infection among injecting drug users and patients with liver disease
is known to be high, yet the magnitude of HCV in the general population, particularly in rural areas, has not been clearly
estimated. A community-based study was used to determine the prevalence of HCV infection in a rural population of north Vietnam
and explore risk factors associated with HCV acquisition.
Method A community-based viral hepatitis seroprevalence study using a multistage sampling method to recruit participants was undertaken.
The study population size (n = 837) had been determined on the basis of estimated hepatitis B virus (HBV) prevalence. Information on demography and potential
risk factors were obtained using face-to-face interviews, and all selected participants were tested for anti-HCV antibody.
Results HCV prevalence in the study population was 1.0% (95% CI: 0.4%–1.9%). Hospital admission (adjusted odds ratio [AOR]: 7.19;
95% CI: 1.59–32.53; P = .01) and having tattoos (AOR: 13.37: 95% CI: 1.86–96.15; P = .01) were independent predictors of HCV infection, and farmers were less likely to have HCV infection than those in other
occupations (AOR: 0.19; 95% CI: 0.04–0.84; P = .02).
Conclusion The prevalence of HCV infection is low in the general rural population in northern Vietnam. An association between HCV infection
and hospital admission and tattoos indicate a need to improve the standards of infection control in healthcare and other settings
in this region.

BACKGROUND: We evaluated associations between human immunodeficiency virus (HIV) infection, herpes simplex virus type 2 (HSV-2) infection, and syphilis among men who have sex with men (MSM) in Peru. METHODS: A surveillance survey of 3280 MSM was conducted; sexual behavior was assessed with a structured computer-assisted self-interview, and serum antibody testing was performed for HIV, HSV-2, and Treponema pallidum. RESULTS: HIV, HSV-2, and syphilis seroprevalences of 13.9%, 46.3%, and 13.4% were detected, respectively. HSV-2 seroprevalence was twice as high in HIV-infected subjects (80.5%) than it was in HIV-uninfected subjects (40.8%) (P < .01), and HSV-2 seropositivity (adjusted odds ratio [AOR], 5.66) was found to be strongly associated with HIV infection. In addition, homosexual self-definition (AOR, 3.12), exchange of sex for money (AOR, 1.61), unprotected sex (no condom) (AOR, 2.81), history of sex work (AOR, 1.89), oral receptive sex (AOR, 1.43), and cocaine use before/during sex (AOR, 2.53) within the preceding 6 months, as well as such sexually transmitted infections (STIs) and STI syndromes as proctitis (AOR, 2.80), genital ulcer disease (GUD) (AOR, 2.06), prior syphilis (AOR, 2.64), genital warts (AOR, 1.70), and self-reported STIs within the preceding 6 months (AOR, 1.61), were also found to be significant predictors of HIV infection. CONCLUSIONS: We found a strong association between HSV-2 seropositivity and HIV infection. Intervention measures against GUD due to HSV-2 infection and syphilis, such as routine testing, early detection, HSV-2 suppressive treatment, and condom distribution, need to be enhanced as part of STI prevention strategies at a national level to effectively reduce HIV infection among MSM in Peru. 相似文献

BACKGROUND/AIMS: To evaluate the strength of association between parenterally transmitted viral hepatitis and specific types of invasive procedures. METHODS: Data from the surveillance system for type-specific acute viral hepatitis (SEIEVA) during the period 1994-1999 were used. The association of acute hepatitis B virus (HBV) and hepatitis C virus (HCV) infection with the potential risk factors (odds ratios (OR)) was estimated comparing 3120 hepatitis B and 1023 hepatitis C cases with 7158 hepatitis A cases, used as controls, by multiple logistic regression analysis. RESULTS: Most procedures resulted in being associated with the risk of acquiring acute HBV or HCV. The strongest associations were: for HBV infection, abdominal surgery (adjusted OR = 3.9; 95% confidence intervals (CI) = 2.0-7.5), oral surgery (OR = 2.7; 95% CI = 1.6-4.5) and gynaecological surgery (OR = 2.6; 95% CI = 1.2-5.5); for HCV infection, obstetric/gynaecological interventions (OR = 12.1; 95% CI = 5.6-26.3), abdominal surgery (OR = 7.0; 95% CI = 3.2-14.9) and ophthalmological surgery (OR = 5.2; 95% CI = 1.1-23.2). Biopsy and/or endoscopy were associated with HCV, but not with HBV infection. CONCLUSIONS: Invasive procedures represent an important mode of HBV and HCV transmission. Since a large proportion of the adult general population is exposed to these procedures and an effective HCV vaccine is not yet available, non-immunological means of controlling iatrogenic modes of transmission are extremely important. 相似文献

Limited health care access and missed opportunities for HIV and other sexually transmitted infection (STI) education and testing in health care settings may contribute to risk of HIV infection. In 2008, we conducted a case-control study of African American men who have sex with men (MSM) in a southeastern city (Jackson, Mississippi) with an increase in numbers of newly reported HIV cases. Our aims were to evaluate associations between health care and HIV infection and to identify missed opportunities for HIV/STI testing. We queried 40 potential HIV-infected cases and 936 potential HIV-uninfected controls for participation in this study. Study enrollees included HIV-infected cases (n=30) and HIV-uninfected controls (n=95) who consented to participate and responded to a self-administered computerized survey about sexual risk behaviors and health care utilization. We used bivariate analysis and logistic regression to test for associations between potential risk factors and HIV infection. Cases were more likely than controls to lack health insurance (odds ratio [OR]=2.5; 95% confidence interval [CI]=1.1-5.7), lack a primary care provider (OR=6.3; CI=2.3-16.8), and to not have received advice about HIV or STI testing or prevention (OR=5.4; CI=1.3-21.5) or disclose their sexual identity (OR=7.0; CI=1.6-29.2) to a health care provider. In multivariate analysis, lacking a primary health care provider (adjusted odds ratio [AOR]=4.5; CI=1.4-14.7) and not disclosing sexual identity to a health care provider (AOR=8.6; CI=1.8-40.0) were independent risk factors for HIV infection among African American MSM. HIV prevention interventions for African American MSM should address access to primary health care providers for HIV/STI prevention and testing services and the need for increased discussions about sexual health, sexual identity, and sexual behaviors between providers and patients in an effort to reduce HIV incidence and HIV-related health disparities. 相似文献

BACKGROUND: Risk factors influencing the incidence of human immunodeficiency virus (HIV) infection were investigated in a case-control study nested within a community-randomized trial of treatment of syndromic sexually transmitted infections (STIs) in rural Tanzania. METHODS: Case patients were persons who became HIV positive, and control subjects were randomly selected from among persons who remained HIV negative. For each sex, we obtained adjusted odds ratios (ORs) and population-attributable fractions (PAFs) for biomedical and behavioral factors. RESULTS: We analyzed 92 case patients and 903 control subjects. In both sexes, the incidence of HIV infection was significantly higher in subjects with an HIV-positive spouse than in those with HIV-negative spouse (men: OR, 25.1; women: OR, 34.0). The incidence of HIV infection was significantly higher in those who became positive for herpes simplex virus type 2 (HSV-2) (men: OR, 5.60; women: OR, 4.76) and those who were HSV-2-positive at baseline (men: OR, 3.66; women: OR, 2.88) than in subjects who were HSV-2 negative. In women, living elsewhere (OR, 3.22) and never having given birth (OR, 4.27) were significant risk factors. After adjustment, the incidence of HIV infection was not significantly associated with a history of injections or STIs in either sex. CONCLUSION: HSV-2 infection was the most important risk factor for HIV infection, which highlights the need for HSV-2 interventions in HIV infection control, and there were particularly strong associations with recent HSV-2 seroconversion. The PAF associated with having an HIV-positive spouse was low, but this is likely to increase during the epidemic. 相似文献

Understanding predisposing factors for sexually transmitted infections (STIs) in young adults may identify targets for public health interventions. We conducted a cross-sectional web-based survey of university students' sexual attitudes, behaviours and lifestyles and self-reported rates of STI. A total of 827 students responded, 22.4% had two or more sexual partners in the previous year with inconsistent condom use and the lifetime prevalence of STIs was 9.6%. Factors associated with a diagnosis of STI were increasing age and number of sexual partners ever, female gender (adjusted odds ratio [AOR] 2.70, 95% confidence interval [CI] 1.31, 5.56) and use of crack (AOR 10.45, 95% CI 1.46, 75.16). For female students, these were increasing age and number of partners ever, whereas for male students having sex with other men (bisexual AOR 4.8, 95% CI 1.02, 22.595, homosexual AOR 17.66, 95% CI 3.03, 103.04) and use of crack (AOR 32.24, 95% CI 3.33, 312.08). Multiple partners and recreational drug use may predict incidence of STI. Prevention strategies need to aim at reducing risk behaviour across various activities. 相似文献

OBJECTIVES: To determine the prevalence of major sexually transmitted infections (STIs) and gynaecological morbidity in women of reproductive age living in rural communities in north-east Brazil and to assess risk factors associated with the presence of STIs. METHODS: A total of 341 women (84%) were examined gynaecologically and colposcopically. The gynaecological history was taken by means of a standardized, pre-tested questionnaire. Cervical smears were obtained and vaginal fluid was collected. Vulvovaginal candidiasis (VC), bacterial vaginosis (BV), trichomoniasis (TV) and syphilis seroreactivity were determined by standard laboratory techniques. Infections with Neisseria gonorrhoeae, Chlamydia trachomatis and human papilloma virus (HPV) were diagnosed by hybrid capture assays using vaginal lavage fluid. Odds ratios (OR) were calculated to assess risk factors associated with STIs. RESULTS: The prevalence of HPV, BV and TV was 26%, 15% and 10%, respectively. VC as well as infections with N. gonorrhoeae and C. trachomatis were detected in 6%; syphilis seroreactivity, in 3%. Multiple infections were very common, and 51% of women had at least one STI. Vaginal discharge, the predominant morbidity (56%), was significantly associated with BV (OR = 6.3; P < 0.001), vulvovaginal itching with VC (OR = 3.5; P < 0.05) and lower abdominal pain with C. trachomatis infection (OR = 2.6; P < 0.04). Colpitis was diagnosed in 27% of women and significantly associated with TV (OR = 3.5%; P < 0.001) and VC (OR = 2.9; P < 0.05). Being unmarried was a significant risk factor for having an STI (OR = 2.4; P < 0.05). Among unmarried women, age (<20 years) was a significant risk factor (OR = 3.3; P = 0.01). CONCLUSIONS: The STIs are highly prevalent in this female population in the rural hinterland of north-east Brazil and associated with considerable morbidity. In view of the expected spread of HIV from the urban centres at the coast to the interior there is an urgent need for providing STI-related health care and health education for adolescents and women in rural Brazil. 相似文献

The prevalence and risk factors for hepatitis delta virus (HDV) infection among Mongolian school children were assessed by detecting the antibody against HDV and HDV RNA, and through structured interviews. The study subjects consisted of 181 children with the past or ongoing hepatitis B virus infection who were investigated during the nationwide serosurvey conducted in 2004. The prevalence of antibody to HDV was 6.1%, with the proportion of 13.6% among hepatitis B surface antigen (HBsAg)-positive subjects, all of whom had HDV RNA. Multivariate logistic regression analyses showed that injections (> 11 times) (odds ratio [OR] = 8.31, 95% confidence interval [CI] = 1.28-54.07) and blood sampling (> 3 times) (OR = 5.34, 95% CI = 1.12-25.53) in health care settings, hospitalization (> 3 times) (OR = 6.20, 95% CI = 1.18-32.71), and cohabitating with patients with chronic hepatitis (OR = 4.57, 95% CI = 1.26-16.55) predicted the seropositivity for antibody to HDV. These results suggest that parenteral exposures in health care settings and household transmission are the main routes of HDV transmission among Mongolian children. 相似文献

The prevalence of hepatitis delta virus antibodies was determined in four cohorts of homosexual or bisexual men positive for hepatitis B surface antigen who were evaluated between April 1984 and April 1985. Antibodies to hepatitis delta virus were found in 16 of 106 men in Los Angeles (15.1%; 95% confidence interval [Cl], 8.3% to 21.9%); 6 of 64 men in San Francisco (9.4%; 95% Cl, 3.5% to 19.3%); 1 of 76 men in Pittsburgh (1.3%; 95% Cl, 0.03% to 7.1%); and 0 of 52 men in Chicago (0%; 95% Cl, 0% to 5.6%). From 44.0% to 65.4% of men negative for hepatitis delta virus and all men positive for hepatitis delta virus but one (P less than 0.0001) were positive for antibodies to human immunodeficiency virus (HIV). In multivariate analysis, infection with hepatitis delta virus was associated with intravenous drug use (adjusted odds ratio [OR] = 6.7, P less than 0.01), with sexual activity as measured by number of partners (adjusted OR = 8.4, p less than 0.01), and probably with rectal trauma (adjusted OR = 3.9, P = 0.17). As with HIV infection, prevalence of hepatitis delta virus infection in homosexual men differs by location and is most likely transmitted both sexually and parenterally. 相似文献

Animal and human studies suggest that Schistosoma mansoni infection may increase risk of human immunodeficiency virus (HIV) acquisition. Therefore, we tested 345 reproductive age women in rural Tanzanian villages near Lake Victoria, where S. mansoni is hyperendemic, for sexually transmitted infections (STIs) and schistosomiasis by circulating anodic antigen (CAA) serum assay. Over one-half (54%) had an active schistosome infection; 6% were HIV-seropositive. By univariate analysis, only schistosome infection predicted HIV infection (odds ratio [OR] = 3.9, 95% confidence interval = [1.3–12.0], P = 0.015) and remained significant using multivariate analysis to control for age, STIs, and distance from the lake (OR = 6.2 [1.7–22.9], P = 0.006). HIV prevalence was higher among women with more intense schistosome infections (P = 0.005), and the median schistosome intensity was higher in HIV-infected than -uninfected women (400 versus 15 pg CAA/mL, P = 0.01). This finding suggests that S. mansoni infection may be a modifiable HIV risk factor that places millions of people worldwide at increased risk of HIV acquisition. 相似文献

AIM: To identify possible risk factors and their synergism for cholangiocarcinoma development.METHODS: A hospital-based, case-control study in which we included 276 cholangiocarcinoma patients [193 extrahepatic cholangiocarcinoma (ECC) and 83 intrahepatic cholangiocarcinoma (ICC)], diagnosed at a training hospital in Korea between 2007 and 2013, and 552 healthy controls matched 2:1 for age, sex, and date of diagnosis. Risk factors for cholangiocarcinoma and possible synergism between those factors were evaluated using conditional logistic regression and synergism index, respectively.RESULTS: There was an association between cholangiocarcinoma and hepatitis B virus (HBV) infection, diabetes mellitus (DM), cholecystolithiasis, choledocholithiasis, and hepatolithiasis, with the adjusted odds ratios (AORs) of 4.1, 2.6, 1.7, 12.4, and 39.9, respectively. Synergistic interaction on the additive model was investigated between HBV infection and DM (AOR = 12.2; 95%CI: 1.9-80.1). In the subgroup analyses, cholecystolithiasis, choledocholithiasis, hepatolithiasis, and DM were significant risk factors for ECC (AOR = 2.0, 18.1, 14.9, and 2.0, respectively), whereas choledocholithiasis, hepatolithiasis, HBV infection, and DM were risk factors for ICC (AOR = 8.6, 157.4, 5.3 and 4.9, respectively). Synergistic interaction was also observed between HBV infection and DM (OR = 22.7; 95%CI: 2.4-214.1). However, there was no synergistic interaction between other significant risk factors for cholangiocarcinoma.CONCLUSION: In this Korean study, HBV infection and DM were found to exert independent and synergistic effects on the risk for cholangiocarcinoma, including ICC. Exploring the underlying mechanisms for such synergy may lead to the development of cholangiocarcinoma prevention strategies in high-risk individuals. 相似文献
