Modification of syphilitic genital ulcer manifestations by coexistent HIV infection

BACKGROUND: Conflicting data exist regarding whether HIV infection leads to changes in the clinical manifestations and severity of genital ulcer disease (GUD). GOAL: To determine the impact of HIV on the etiology and clinical severity of GUD. STUDY DESIGN: From July 1990 to July 1992, consecutive patients presenting to the two Baltimore City Health Department (BCHD) Sexually Transmitted Diseases clinics were approached as candidates for enrollment in a prospective study to determine factors associated with the transmission and acquisition of sexually transmitted diseases (STDs). RESULTS: Of the 1368 patients who presented to the BCHD, 214 (16%) had genital ulcerations: 160 (21%) of 757 men and 54 (9%) of 611 women. Among the patients with GUD who had undergone HIV testing, 28 (14%) of 204 were infected with HIV: 25 (17%) of 151 men and 3 (6%) of 53 women. Although both groups-those infected with HIV and those not infected with HIV--presented with GUD of similar duration (10 versus 11 days; P = 0.17), multiple lesions were found more frequently in men with HIV infection than in uninfected men: 87% versus 62% (P = 0.02). Although not statistically significant, GUD in men with HIV infection more often were deep (64% versus 44%, respectively) rather than superficial (36% versus 57%, respectively; P = 0.08), and larger (505 mm(2) versus 109 mm 2; P = 0.06). Primary syphilis caused more GUD among men with HIV infection than among uninfected men: 9 (36%) of 25 versus 24 (19%) of 126, respectively (P < 0.01). Secondary syphilis was diagnosed with concomitant GUD more frequently among men with HIV infection than among uninfected men: 3 (13%) of 25 versus 3 (2%) of 123, respectively (P < 0.01). CONCLUSIONS: In this study, patients who presented with GUD were more likely to be infected with HIV. A higher proportion of men with HIV infection had multiple lesions, and the lesions were more likely to be caused by syphilis.     

Human immunodeficiency virus infection and genital ulcer disease in South Africa: the herpetic connection

BACKGROUND AND OBJECTIVES: While genital ulcers are a risk factor in HIV infection, the association of specific agents of genital ulcer disease (GUD) with HIV infection may vary. GOAL: To determine the etiology of GUD in HIV-infected and HIV-uninfected men attending sexually transmitted disease (STD) clinics in Durban, Johannesburg, and Cape Town, South Africa, and the association of previous and current sexually transmitted infections with HIV infection in men with ulcerative and nonulcerative STDs. STUDY DESIGN: A cross-sectional study of 558 men with genital ulcers and 602 men with urethritis. RESULTS: Patients with GUD were more likely to be infected with HIV than patients with urethritis (39.4% versus 21.4%, P< or =0.001). Herpes simplex virus 2 (HSV-2) was the most common agent identified in ulcer specimens (35.9%), and was detected in a significantly higher proportion of ulcer specimens from HIV-infected patients than in specimens from HIV-uninfected patients (47.4% versus 28.2%, P< or =0.001). Patients infected with HIV-1 were significantly more likely to have HSV-2 infection, as measured by the presence of the antibody to glycoprotein G-2, than patients not infected with HIV (63.1% versus 38.5%, P< or =0.001). Patients infected with HIV-1 were also significantly more likely to have initial HSV-2 infection than HIV-uninfected patients with GUD (50.0% versus 31.6%, P = 0.007). Haemophilus ducreyi was detected in 31.7% of ulcer specimens; prevalence did not vary by HIV-infection status. Treponema pallidum DNA was detected significantly less frequently in ulcer specimens from patients infected with HIV than in specimens from patients not infected with HIV (10.2% versus 26%, P< or =0.001); no association was found between HIV-infection status and fluorescent treponemal antibody absorption test seroreactivity, even when men with M-PCR-positive syphilis lesions were excluded from the analyses. CONCLUSION: The authors found that HSV-2 is a more common etiology of GUD than has been suggested by previous studies conducted in South Africa; serologic evidence of HSV-2 infection and current cases of genital herpes are strongly associated with HIV infection among men who present to STD clinics with GUD or urethritis.     

Etiology of genital ulcer disease and association with human immunodeficiency virus infection in two tanzanian cities

BACKGROUND: The etiological agent is usually not established in cases of genital ulcer disease (GUD) in Tanzania, since diagnosis and treatment of this disease are based mainly on clinical rather than microbiologic parameters. GUD increases the risk of infection with HIV. However, the association between specific GUD infections and HIV infection has not been fully investigated. GOAL: The goal was to determine the etiology of GUD and the prevalence of HIV infection in patients with GUD in urban areas of Tanzania. STUDY DESIGN: A total of 102 clinical specimens were collected from 52 and 50 patients with GUD in Dar es Salaam and Mbeya, respectively, and from 93 patients with genital discharge in a cross-sectional study. Two polymerase chain reaction (PCR) assays were used to identify either a single target DNA or all three DNAs of the major causes of GUD: Haemophilus ducreyi, Treponema palladum and herpes simplex virus type 2 (HSV-2). The sera from all patients were tested for antibodies to HIV and T palladum. RESULTS: In Dar es Salaam, DNA from HSV-2, and was detected in 63%, 13%, and 2%, respectively, of the 52 genital ulcer specimens. The corresponding figures in Mbeya were 34%, 10%, and 0% of 50 specimens. Overall, 9% of the 102 patients with GUD were infected with both HSV-2 and, and 39/102 genital ulcer specimens (38%) were negative for the DNA of all three pathogens. The HIV infection rates among GUD patients were 46% and 52% in Dar es Salaam and Mbeya, respectively; among the non-GUD patients, the corresponding rates were 35% and 45%, respectively. The HIV infection rate in Dar es Salaam was significantly higher among women (11/14; 78%) than among men (13/38; 34%) (P = 0.004). Among the HIV-seropositive GUD patients, 71% and 46% (P < 0.003) were coinfected with HSV-2 in Dar es Salaam and Mbeya, respectively. Furthermore, women with HSV-2 in Dar es Salaam were significantly more likely to be HIV-infected than men (60% versus 39%; P相似文献   

Accuracy of clinical diagnosis of genital ulcer disease

In Africa, establishment of an accurate clinical diagnosis in cases of genital ulcer disease is difficult owing to atypical presentation of ulcerations and mixed infections. This is compounded by the frequent lack of suitable laboratory facilities. In 240 cases of genital ulcer disease among mineworkers in Carletonville, South Africa, this study endeavored to correlate the clinical diagnosis with laboratory findings. Clinical accuracy and positive and negative predictive values were determined for each type of genital ulcer disease encountered. Overall, the accuracy of clinical diagnosis was 68% for single infections, 80% for chancroid, 55% for primary syphilis, 27% for lymphogranuloma venereum (LGV), and 22% for genital herpes. Adequate laboratory facilities are indispensible for the establishment of an accurate etiologic diagnosis of genital ulcer disease and thus the institution of appropriate antimicrobial therapy.     

Epidemic crack cocaine use linked with epidemics of genital ulcer disease and heterosexual HIV infection in the Bahamas: evidence of impact of prevention and control measures

BACKGROUND: Epidemic freebase/crack cocaine use began in the Bahamas in 1982, closely followed by epidemics of genital ulcer disease (GUD) and HIV infection. Numbers of new clients receiving ambulatory treatment for cocaine use in Nassau peaked in 1984. GOAL: To assess interrelations among epidemics of crack use, GUD, and HIV infection. STUDY DESIGN: The study was designed for review and comparison of temporal trends in ambulatory and inpatient treatment of cocaine users and in numbers of cases of sexually transmitted disease (STD) and HIV infection in the Bahamas. A retrospective case-control study of cocaine use and STDs was performed at the Comprehensive Dermatovenereology Clinic in Nassau. RESULTS: Ambulatory visits and inpatient admissions for cocaine use peaked in 1984 and 1987, respectively. GUD cases increased 12-fold in the Bahamas from 1983 to the period of 1985-1987 and then declined. At the Comprehensive Dermatovenereology Clinic, gonorrhea cases outnumbered bacterial GUD cases approximately 10:1 in 1982 and 1983, but the latter increased to outnumber gonorrhea cases in 1985 and 1987-1988. Annual HIV seroprevalences at new-problem visits rose from less than 0.3% in 1986 to 12.9% by 1994 and then leveled off. Cocaine use among patients seen with STD from 1985 through 1990 was significantly associated with GUD (odds ratio [OR], 3.3; 95% CI, 2.1-5.1), secondary syphilis (OR 5.5; 95% CI, 2.4-12.6), and HIV infection (OR, 8.1; 95% CI, 4.3-15.2). CONCLUSIONS: In temporally linked successive epidemics of cocaine use, GUD, and HIV infection, case-control analyses confirmed the association of cocaine use with GUD and with HIV infection. Declining GUD and HIV seroprevalence stabilization followed declines in cocaine use and implementation of syndromic management of GUD, as well as intensified partner-notification efforts.     

Association between HIV-1 infection,the etiology of genital ulcer disease,and response to syndromic management

BACKGROUND: Reports on the effect of HIV-1 infection on healing rates of ulcers are conflicting. GOAL: The goal was to determine the etiology and response to treatment of genital ulcer disease (GUD) in relation to HIV-1 infection. STUDY DESIGN: This was a cohort study of patients with GUD treated with local syndromic management protocols. RESULTS: Among the 587 recruited, the prevalences of infections due to HSV, Treponema pallidum, Chlamydia trachomatis (lymphogranuloma venereum [LGV]), Haemophilus ducreyi, Calymmatobacterium granulomatis, and HIV-1 were 48%, 14%, 11%, 10%, 1%, and 75%, respectively. The prevalence T. pallidum of was higher among men (P = 0.03), and an association was seen among HIV-1-seronegatives on univariate and multivariate analyses (P < 0.001; = 0.01). The prevalence of C trachomatis (LGV) was higher among females (P = 0.004), and an association was seen among HIV-1-seropositives on univariate analysis (P = 0.04). At follow-up, 40/407 (10%) showed a decreased healing tendency, not associated with ulcer etiology or HIV-1 seropositivity. CONCLUSION: Response to syndromic management of GUD was acceptable and not associated with HIV-1 coinfection.     

Soap and water prophylaxis for limiting genital ulcer disease and HIV-1 infection in men in sub-Saharan Africa.

In general, East, Central and Southern Africa appear to be worse affected by HIV-1 infection than West Africa. So far there is little evidence to suggest that differences in either sexual behaviour or numbers of sexual partners could account for this disparity. Two risk factors in men for acquiring HIV-1, that tend to vary along this geographical divide, are lack of circumcision and genital ulcer disease (GUD) which are much less common in West Africa. Although uncircumcised men with GUD are an important high frequency HIV-1 transmitter core group, few interventions have targeted such individuals. Given the recent expansion in AIDS-related technologies, is it possible that methods effective in limiting GUD in the preantibiotic era have been overlooked? During the first and second world wars, chancroid, the commonest cause of GUD in Africa today, was controlled successfully with various prophylactics including soap and water. Many parts of Africa are undergoing social upheaval against a background of violence, and in this environment soap and water prophylaxis would now seem to merit re-evaluation as an intervention for preventing both GUD and HIV-1 in uncircumcised men. By facilitating healing of traumatic, inflammatory and infected penile lesions, pre- and post-exposure prophylaxis with soap and water could be a cheap and effective method for decreasing the risks of acquiring GUD and HIV in this vulnerable group of uncircumcised men.     

Recent advances in management of genital ulcer disease and anogenital warts

ABSTRACT:   Genital ulcer disease (GUD) constitutes a major public health problem. Most of them are the result of sexually transmitted diseases. Genital herpes, syphilis, lymphogranuloma venereum, granuloma venereum, or chancroid are the commonly encountered GUD. The treatment modalities for these disorders have changed with advent and use of drugs such as azithromycin. The treatment modalities differ in patients with HIV disease. Further vaccines for herpes genitalis and human papilloma virus has opened new avenues in management of these diseases. In regions where there are no diagnostic facilities or where the costs of diagnostic tests are prohibitive, syndromic management of GUD is preferred.     

Sexual behaviour in Zulu men and women with genital ulcer disease.

OBJECTIVE--To investigate patterns of sexual behaviour in men and women with genital ulcer disease (GUD) and their relevance to HIV-1 transmission. METHODS--A sexual behaviour questionnaire was administered by the same interviewer to all participants who were also entered into a study of the microbial aetiology of GUD. SETTING--City Health Sexually Transmitted Diseases Clinic, King Edward VIII Hospital, Durban, South Africa. PARTICIPANTS--100 Zulu men and 100 Zulu women. RESULTS--36 (%) of men and 36 (%) of women had continued with sexual intercourse despite GUD. Patients with donovanosis and secondary syphilis were more likely than those with other causes of GUD to have intercourse despite ulcers. During swab collection bleeding was observed from ulcers in 59 women and 26 men. Prostitutes were not identified and were rarely named as source contacts. Men had more sexual partners (190) than women (122) during the previous three months. Condom use was minimal. Men who migrated between urban and rural areas appeared to have the most sexual partners. Urban women had more partners than women from rural areas. CONCLUSIONS--Men and women with GUD are practising riskful sexual behaviour and could benefit from behaviour modification programmes. In this community men who travel between urban and rural areas and who present late with GUD that bleeds easily are probably the most important high-frequency HIV transmitter core group. A significant potential risk of blood to blood contact during sexual intercourse exists in patients with GUD.     

Herpes simplex virus infection and genital ulcer disease among patients with sexually transmitted infections in Dar es Salaam, Tanzania

The relative importance of Haemophilus ducreyi and Treponema pallidum in genital ulcer disease in Africa has decreased recently, whereas that of herpes simplex virus (HSV) type 2 has increased. We analysed 301 lesional specimens from Tanzanian patients with genital ulcer disease for the presence of H. ducreyi, T. pallidum and HSV-1/HSV-2 by performing a separate PCR for each pathogen. Infectious agents were detected in 211 (70%) of the cases. A single pathogen was found in 191 samples and two or more pathogens in the remaining 20. HSV-2 represented 83% of all identified pathogens, HSV-1 8%, T. pallidum 4% and H. ducreyi 5%. HSV-1 was identified as a single pathogen in four samples, in combination with others in an additional 14 samples. Thus, HSV-1 can also be the cause of genital ulcer disease in Africa. Regular surveillance of genital ulcer disease aetiology is important in programs for management of genital ulcer disease and HIV in Africa.     

The clinical diagnosis of genital ulcer disease in men in the tropics

Since the clinical diagnosis of genital ulcers without laboratory confirmation is not reliable in developed countries, we postulated that clinical diagnosis alone would be no more reliable in developing countries. A presumptive clinical diagnosis of chancroid, genital herpes, syphilis, or lymphogranuloma venereum was made for 100 male patients at the Special Treatment Clinic in Nairobi, Kenya. This diagnosis was then compared to the final diagnosis determined by laboratory identification of the pathogen, by culture, or by serologic response. In 64 patients, a final diagnosis of either chancroid, syphilis, or genital herpes was established. The diagnostic accuracy varied from 75% for chancroid to 42% for syphilis and 43% for herpes. The overall diagnostic accuracy was 66%. The predictive values of positive clinical diagnoses were 84% for chancroid, 60% for syphilis, and 75% for herpes. Thus, clinical diagnosis of genital ulcer disease was not sufficiently reliable in this study.     

Improving the accuracy of syndromic diagnosis of genital ulcer disease in Malawi

OBJECTIVES/GOAL: Most resource-poor settings rely on syndromic criteria to diagnose genital ulcer disease (GUD). However, the etiologic pathogens of GUD vary temporally and geographically, and current criteria may not reflect changes in the prevalence of specific pathogens. STUDY: In 1999, we estimated the prevalence of Treponema pallidum (Tp), herpes simplex virus (HSV), and Haemophilus ducreyi (Hd) in Malawi. We then used regression coefficients of independent correlates of HSV and Hd to develop weighted diagnostic algorithms, in which weights were beta-coefficients corresponding to each factor. RESULTS: Overall, a decrease in the proportion of sexually transmitted disease attributable to GUD was noted in 7 years. Thirty-five percent were attributable to HSV, 30% to H. ducreyi, and 4% to T. pallidum. Areas under the receiver operating characteristic curves for weighted and unweighted HSV diagnostic algorithms were 67.6% and 66.5%, respectively. There was no significant difference in the explanatory performance of the weighted and unweighted algorithms. CONCLUSIONS: Unweighted algorithms can therefore be used to improve diagnostic accuracy of GUD.     

Metastatic Crohn's disease mimicking genital pyoderma gangrenosum in an HIV patient

The differential diagnosis of ulcerative genital lesions in patients with high risk sexual habits can be a challenge even for dermatologists. We present the case of a 27-year-old HIV-positive male with a history of recalcitrant genital ulcers. Microbiology studies were negative. A skin biopsy and a sample from a perineal fistula showed granulomatous infiltrates. The patient was treated with prednisone, metronidazole and aminosalicylates, showing complete resolution of the lesions in a few weeks. The clinical picture and histological findings are consistent with the diagnosis of cutaneous metastatic Crohn's disease. Although infrequent, metastatic Crohn's disease should be suspected in cases of recalcitrant ulcerative conditions, even in the absence of intestinal disease.     

The impact of HIV infection and immunodeficiency on human papillomavirus type 6 or 11 infection and on genital warts

BACKGROUND: HIV infection and associated immunodeficiency are known to alter the course of human papillomavirus (HPV) infections and of associated diseases. GOAL: This study investigated the association between HIV and HPV and genital warts. STUDY DESIGN: HPV testing and physical examinations were performed in two large prospective studies: the Women's Interagency HIV Study (WIHS) and the HIV Epidemiology Research Study (HERS). Statistical methods incorporating dependencies of longitudinal data were used to examine the relationship between HIV and HPV and genital warts. RESULTS: A total of 1008 HIV-seronegative and 2930 HIV-seropositive women were enrolled in the two studies. The prevalence of HPV 6 or 11 was 5.6 times higher in HIV-seropositive women in the WIHS and 3.6 times higher in the HERS. Genital wart prevalence increased by a factor of 3.2 in the WIHS and 2.7 in the HERS in HIV-seropositive women. In the WIHS, infection with HPV type 6 or 11, in comparison with no HPV infection, was associated with odds of genital wart prevalence of 5.1 (95% CI: 2.9-8.8), 8.8 (95% CI: 6.1-12.8), and 12.8 (95% CI: 8.8-18.8) in HIV-seronegative women, HIV-seropositive women with > or =201 CD4 cells/microl, and HIV-seropositive women with < or =200 CD4 cells/microl, respectively. In the HERS, infection with HPV type 6 or 11 was associated with odds of 2.7 (95% CI: 1.6-4.6), 4.9 (95% CI: 3.2-7.7), and 5.3 (95% CI: 3.3-8.5) in these same groups. Other HPV types showed a similar dose-response relation, but of substantially lower magnitude and statistical significance. CONCLUSIONS: HIV infection and immunodeficiency synergistically modified the relation between HPV 6 or 11 infection and genital wart prevalence.
