RESUMO
Longitudinal data from a case series indicated that clearance rates (95% CIs) of anogenital warts (AGW) by silver nitrate (n = 14) and podophyllin (n = 34) were 93% (79.35, 100) and 14.7% (3, 27) respectively; and RR, 6.31 (95% CI 2.77, 14.37, p = 0.0(5)2), relative benefit increase, 532% (410, 654), and NNT, 1 (1, 2). The total effort needed US$28(BB$56) vs US$598 in 1-3 vs 1-37 visits to achieve one successfully treated patient respectively. While subject to the errors of an open, non-randomized case series, silver nitrate was highly efficacious and cost-effective and should replace podophyllin at the Winston Scot Polyclinic.
Datos longitudinales de una serie de casos indicaron que las tasas de eliminación (95% CI) de verrugas anogenitales (VAG) mediante nitrato de plata (n = 14) y podofilina (n = 34) fueron 93% (79.35, 100); y 14.7% (3, 27) respectivamente; y RR, 6.31 (95% CI 2.77, 14.37, p = 0.0(5)2), aumento relativo de beneficios, 532% (410, 654), y NNT, 1 (1, 2). El esfuerzo total necesitó $28 USD (BB$56) vs $598 USD en 1-3 vs 1-37 visitas para lograr un paciente tratado con éxito respectivamente. Aunque sujeto a los errores de una serie de casos abierta no aleatorizada, el nitrato de plato fue altamente eficaz y costo-efectivo y debe reemplazar la podofilina en Winston Scot Polyclinic.

INTRODUCTION: A retrospective study in the referral centre for sexually transmitted infections (STIs) in Singapore to describe the epidemiology and treatment outcome of patients with anogenital warts. SUBJECTS AND METHODS: We reviewed the case records of 301 patients with anogenital warts who were seen over a 1-year period (1999). We also attempted to interview every patient by telephone to find out if they had any clinical recurrences for which treatment was sought elsewhere. RESULTS: There were 255 males and 46 females with a mean age of 34 years. Two hundred and nineteen (72.8%) presented with symptoms lasting 12 weeks or less. In males, warts occurred most frequently in the preputial cavity (52.5%) and on the penile shaft (40.8%). In females, they occurred most frequently on the external genitalia (91.3%). Two hundred and thirty-five males were treated with cryotherapy and 69% (95% CI, 62.6% to 74.8%) achieved clinical resolution after a mean of 6 treatment cycles. Seven males were treated with podophyllin 0.25% in ethanol and 71% (95% CI, 29.0% to 96.3%) were clinically cured after a mean of 4 treatment cycles. Thirty-nine females were treated with cryotherapy and 67% (95% CI, 49.8% to 80.9%) achieved clinical cure after a mean of 4 treatment cycles. Of the 290 patients treated at the centre, 212 (73%; 95% CI, 67.3% to 77.8%) patients (184 males, 28 females) achieved clinical cure after a mean of 7 weeks (range, 1 to 34 weeks); 90% (95% CI, 86.0% to 93.2%) of them by 15 weeks. Seven-two patients defaulted follow-up and 6 responded partially to treatment. Of the 212 patients who achieved clinical cure, 195 were interviewed by telephone, on an average, 17.7 months after clinical resolution. Thirty-seven (19%; 95% CI, 13.7% to 25.2%), all males, relapsed clinically after a mean of 100 days (range, 5 to 329 days); 90% (95% CI, 84.6% to 93.6%) relapsed by 228 days. CONCLUSIONS: Podophyllin 0.25% in ethanol was the most cost-effective treatment for males. One in 5 patients had a recurrence of their warts and most had their recurrence within 8 months of initial resolution.

BACKGROUND: Genital warts is a common sexually transmitted disease treated by a variety of medical specialists. Standard therapies offer symptomatic relief but cannot ensure lasting remission. Using the clinical literature, claims databases, and a panel of experienced practitioners, the relative efficacy, cost, and cost effectiveness of five common treatments for genital warts were assessed in this study. METHODS: We reviewed the clinical literature for the following genital wart therapies: podofilox, podophyllin, trichloroacetic acid, cryotherapy, and laser therapy, focusing on their relative efficacy. Physicians experienced in treating genital warts defined standard treatment protocols for men and women patients with moderate wart burdens. Using national claims data and protocols developed by physicians, we derived three economic models based on provider charges, third-party payments, and a resource-based relative value scale, respectively. RESULTS: The literature review demonstrated highly variable success and recurrence rates among treatment methods and failed to show that one treatment provides consistently superior efficacy. In the economic models, treating women generally proved more costly than treating men per episode of care. This was due to the need for more extensive follow-up visits in the treatment of women. Total costs were highest for cryotherapy and lowest for a patient-applied therapy that reduced the need for follow-up visits. CONCLUSIONS: Clinicians should consider both clinical and cost issues when choosing the appropriate treatment for patients with genital warts.

The cost effectiveness of 25% podophyllin resin and 0.5% podophyllotoxin solution in the treatment of genital warts in Genitourinary Medicine Clinic attenders was studied. Although the average treatment cost for a course of podophyllotoxin was more than that for podophyllin resin (20.75 pounds v. 14.95 pounds respectively) the overall cure rate with podophyllotoxin was 66% as opposed to 34.6% with podophyllin. When the costing of secondary treatment options was considered the cost per patient cured of warts with podophyllin resin was 27.15 pounds compared with 25.73 pounds for podophyllotoxin solution (not significant).
