BACKGROUND AND OBJECTIVES: The most important risk factor for cervical neoplasia is genital infection with certain types of human papillomavirus (HPV). Genital warts (GW) are an easily recognizable condition caused by HPV. Although only a fraction of HPV infections are clinical, a history of ever having had GW could serve as a marker for exposure to HPV. GOALS: To study the risk factors for ever having had GW. The association of GW with abnormal Papanicolaou (Pap) smear and relation to cervical neoplasia is also discussed. STUDY DESIGN: A case-control study among 10,838 women aged 20 to 29 years and reporting at least one lifetime sexual partner. The women were participants in a prospective cohort study on the relationship between HPV and cervical neoplasia in Copenhagen, Denmark. Data were obtained by means of personal interviews using structured questionnaires. RESULTS: In all, 1,820 women (17%) reported ever having had GW. The most important risk factor was the number of lifetime of sexual partners (adjusted odds ratio 5.2; 95% confidence interval: 3.4-8.0) for at least 40 partners vs. 1 to 2 partners). The number of regular partners, sexually active years, a history of chlamydial infection, and smoking were also associated with the risk of ever having had GW. Women who had had GW were 1.9 times more likely than other women to report an abnormal Pap smear. CONCLUSIONS: The study confirms the sexual transmission of the infection. There is also good concordance between risk factors for ever having had GW and cervical neoplasia. A close relationship between having had GW and an abnormal Pap smear was observed.

Cancer-associated human papillomavirus (HPV) types are detected in genital warts removed from immunosuppressed individuals more commonly than from those occurring in otherwise healthy individuals. The prognosis of genital warts containing cancer-associated HPV types is not known. Because it is assumed that genital warts are benign lesions, they are usually treated by destructive therapies without prior knowledge of histopathology. The aim of the present study was to determine whether genital warts from individuals with or without human immunodeficiency virus (HIV) contain high-risk HPV types or areas of dysplasia. The study design was a nonrandomized analysis of genital warts removed by excision biopsy from 15 HIV-infected patients and 15 HIV-negative patients. The tissue was analyzed for HPV DNA by hybrid capture, and microscopic sections of each biopsy were examined for areas of dysplasia. Genital warts from HIV-infected patients contained cancer-associated ("high risk") HPV types in 9 of 15 cases, including 1 that contained only a high-risk type. High-grade dysplastic abnormalities were present in 2 of the 15 lesions from this group, both of which contained high-risk HPV types. Four genital warts removed from HIV-negative patients contained high-risk HPV types, but none contained dysplastic abnormalities. It is concluded that genital warts from HIV-infected patients often contain high-risk HPV types. Such lesions may exhibit dysplastic changes. The frequency of dysplastic changes in genital warts from HIV-infected patients is not known. Biopsy of genital warts may be indicated prior to additional therapy in HIV-infected patients, and surgical removal should be considered as a preferred treatment option in these patients.

Epidemiology of genital warts in England and Wales: 1971 to 1994.

Simms I, Fairley CK.

Communicable Disease Surveillance Centre, Colindale, London.

OBJECTIVE: To describe the epidemiology of genital warts in England and Wales over the period 1971 to 1994. METHOD: Retrospective study of available statistics. RESULTS: The rate of attendance for genital warts increased by 390% and 594% for men and women respectively between 1971 and 1994. Most of this increase occurred between 1980 and 1986. From 1986 to 1991 virtually no change occurred, but since 1992 the rate of attendance has risen by 15%. The ratio of male to female cases has declined steadily from 1.85 in 1971 to 1.34 in 1994. Rates of attendance for first attack in men were highest in the 20 to 24 year age group whereas for women it peaked in those aged 16 to 24 years. Regional data indicate that the rate of attendance has increased consistently over England and Wales during this period. CONCLUSIONS: Rates of genital warts have risen substantially over the past 25 years. If these are a reflection of changes in sexual behaviour then the rise since 1992 is of considerable concern particularly for the incidence of cervical cancer in the coming decades.

Prevalence of human papilloma virus genital infections in sexually transmitted diseases clinic attendees in Ibadan.

All patients, who presented at the Sexually Transmitted Disease clinic of the University College Hospital, Ibadan, between the period of August 1996 and January 1998 were included in this study. They were examined for genital infections in order to determine the prevalence rate of Human papilloma virus genital infection (genital warts) among them. Out of the 1,373 patients seen in the clinic during the period, 861 (62.71%) had STD while the remaining 512 (37.29%) had other conditions. Out of these 861 cases, 69 (8.01%) had HPV genital infection, while the remaining 792 (91.9%) had other STDS. Of these 69 cases of genital warts, 35 (50.7%) were males while 34 (49.3%) were females. Their ages ranged between 17 and 74 years, with the peak incidence in the 20-29 years age group. 32 (46.4%) had concurrent genital infections with non-gonococcal urethritis and cervicitis 9(13%) constituting the most common type. The highest incidence (36.2%) of this condition was found among petty traders while the lowest was found among the business executives and applicants. In 67 (97%) of these patients, the nature of sexual intercourse was vaginal, while in 1 (1.5%) it was oral and another 1 (1.5%) both vaginal and oral. 26 (37.7%) of the patients had just one sexual partner, while 7 (8.1%) had 2 or more. Only 2 (2.9%) admitted to have had any sexual contact with commercial sex workers. The sites of warts in males include the shaft of the penis, the glans penis, perineum and intrameatum. In females, warts were found in the vulva, vagina, cervix, perineum and perianal regions. 42 (60.9%) of these patients were placed on 20% podophyllin on tincture of benzoin, 17 (24.6%) on cryotherapy and 1 (1.5%) on both. They all did well on the different treatment regimens except for 1 (1.5%) that had to change from podophyllin to cryotherapy when there was no reduction in size. 11 (15.9%) were however lost to follow up.

BACKGROUND: Condylomata acuminata is one of the most common sexually transmitted diseases (STDs) diagnosed in the United States, yet relatively little research has been conducted on the determinants of this disease in well-defined populations. GOAL: To determine the exposures that predispose a woman to the development of condylomata acuminata or genital warts. STUDY DESIGN: A population-based case-control study was conducted among enrollees of Group Health Cooperative of Puget Sound. Patients (94 women with incident and 55 women with recurrent condyloma) were diagnosed between April 1, 1987 and September 30, 1991. Control subjects were 133 women without a history of genital warts. An in-person interview was conducted to collect information on subject characteristics, exposures, and on all episodes of genital warts. RESULTS: Women with five or more partners within the 5 years before reference date were over seven times more likely to have incident condyloma (relative risk [RR], 7.5; 95% confidence interval [CI], 3.1-18.1) and over 12 times more likely to have recurrent condyloma (RR, 12.8; 95% CI, 4.2-38.9) compared with women with only one sexual partner during this time period. An increased risk of incident condyloma was also associated with a history of any STD (RR, 2.6; 95% CI, 1.1-5.8), a history of oral herpes (RR, 2.2; 95% CI, 1.1-4.4), and a history of allergies (RR, 2.0 95% CI, 1.0-3.8). Our data did not support a strong association between risk of condyloma and smoking or recent use of oral contraceptives. CONCLUSION: Our results suggest that risk of condyloma is primarily related to sexual behavior. We did not observe a strong association between risk of condyloma and many of the exposures considered to be potential cofactors for anogenital cancers associated with other types of human papillomaviruses.
