Comparison Between Efficacy of Topical 25%Podophyllin and Cryotherapy on Genital Warts

Overview

Human papilloma virus (HPV), is the major prevalent cause of sexually transmitted disease affecting genitalia, causing Condylomata Accuminata, also known as external genital warts or anogenital warts.¹ Occurring in men and women with a prevalence rate of 0.6-1.2% worldwide. It primarily affects those in the age range of 20-25 years. Human papilloma virus infections subclinically are primarily caused by either type HPV- 6 or HPV- 11. A vast variety of treatment options are available to treat CA , including immunomodulators ( imiquimod, purified protein derivative and the HPV vaccine), physical ablation ( cryotherapy and electrodessication) and topical cytotoxic drugs ( TCA, phenol, 5- fluorouracil, retinoids, podophyllin and bleomycin)¹ . Although there are multiple effective treatment are present for EGW, no single treatment has been identified as the best ideal way to treat CA. Cryotherapy causes the destruction of keratinocytes infected with HPV by using below zero temperature and leading to thermal cell necrosis. Podophyllum peltatum and Podophyllum emodi are the main source of Podophyllin, a refined plant- based resin.¹² It works by attaching itself to the infected cell's microtubule disturbing the linking process which stops the mitotic process during the metaphase stage of cell division causing the death of epithelial cell. Study will include patients which will be divided into 2 groups A \& B, 48 in each group. Group A will receive topical 25% podophyllin resin via cotton bud under supervision once weekly for 04 weeks. Group B will receive cryotherapy of 10sec freeze cycle twice weekly for 04 weeks. Patient will be followed at interval of 4 weeks and 8 weeks from start of treatment. Treatment will be considered efficant when decrease in the number of warts is clinically evident at follow up visits. Efficacy of treatment will be graded as 'excellent' \>90% clearance, 'good'60-89% clearance, 'satisfactory'30-59% clearance and 'poor'\<30% clearance.

Human papilloma virus (HPV), is the major prevalent cause of sexually transmitted disease affecting genitalia, causing Condylomata Accuminata, also known as external genital warts or anogenital warts. Occurring in men and women with a prevalence rate of 0.6-1.2% worldwide. It primarily affects those in the age range of 20-25 years. Human papilloma virus infections subclinically are primarily caused by either type HPV- 6 or HPV- 11.Topical medicines, surgeries and other treatment are among the many possible therapeutic options available. However recurrence and treatment failure are observed with almost all the available treatment after the warts have been visibly cleared. EGW management poses a major obstacle therapeutically . The patient's immunological condition determine the outcome of the warts , if they are left untreated , they could go away spontaneously, get bigger in size and numerous , or remain the same. The treatment goal is to remove visible warts in order to potentially reduce their infectious , if not the carcinogenic properties. In this study we will compare the efficacy of topical 25% podophyllin resin versus cryotherapy for the treatment of warts . Study will include patients which will be divided into 2 groups A \& B, 48 in each group. Group A will receive topical 25% podophyllin resin via cotton bud under supervision once weekly for 04 weeks. Group B will receive cryotherapy of 10sec freeze cycle twice weekly for 04 weeks. Patient will be followed at interval of 4 weeks and 8 weeks from start of treatment.
