Local Management of Anogenital Warts in Non-immunocompromised Adults: A Systematic Review and Meta-analyses of Randomized Controlled Trials.

ABSTRACT:

Introduction

Several therapeutic options are available to manage anogenital warts (AGWs). However, no hierarchy of treatments is provided in the latest European and American recommendations. This study aimed to determine the efficacy and safety of local treatments for the management of AGWs.

Methods

A search was conducted through 12 databases from inception to August 2018. All randomized controlled trials (RCTs) in which at least one parallel treatment group composed of immunocompetent adults with AGWs received at least one provider-administered or patient-administered treatment were included. Risk of bias assessment and meta-analyses of aggregated study data were performed on the basis of the Cochrane Handbook, and quality of evidence evaluation followed the Grading of Recommendation Assessment, Development and Evaluation (GRADE) approach. Primary endpoints were complete clearance and recurrence at 3 months.

Results

Seventy RCTs (9931 patients) were included. All but four RCTs had a high risk of bias. CO₂ laser was slightly more efficacious than cryotherapy [risk ratio (RR) 2.05; 95% confidence interval (CI) 1.61-2.62], with fewer recurrences at 3 months (RR 0.28; 95% CI 0.09-0.89). Electrosurgery was slightly more efficacious than cryotherapy. No differences in efficacy or side effects were found between cryotherapy and imiquimod or trichloroacetic acid. Podophyllotoxin gel was slightly more efficacious than podophyllotoxin cream. 5-Fluorouracil (5-FU) was slightly more efficacious and caused less erosion than CO₂ laser (RR 1.37; 95% CI 1.11-1.70).

Conclusion

The vast majority of included RCTs had a low level of evidence, thereby preventing the establishment of a hierarchy of treatments. Nevertheless, our results provide an overview of the main AGW treatments available for general practitioners and specialists. While provider-administered treatments are superior, patient-administered treatments (e.g., imiquimod, podophyllotoxin) are useful solutions for compliant patients.

Project description:BackgroundHuman papillomavirus (HPV), primarily genotypes 6 and 11, cause the majority of cases of anogenital warts (AGW). Although benign, AGW are associated with a substantial economic and psychosocial burden. Several vaccines have been developed to prevent HPV. The objective of this study was to describe the epidemiology and healthcare resource utilization of AGW in Morocco, as well as the associated costs of treatment from the public healthcare perspective.MethodsThis was a descriptive analysis of questionnaire data obtained via a Delphi panel. The panel consisted of 9 physicians practicing in public hospitals in Morocco (4 dermatologists and 5 obstetricians/gynecologists). The questionnaire collected data on physician and practice characteristics, diagnostic tests and procedures, treatments, and follow-up (including recurrence) of patients with AGW. Questionnaire items on which ≥ 70% of respondents agreed were considered as having consensus. Costs associated with diagnosis, treatment, and follow-up were calculated in Moroccan dirham (MAD) and converted to euros (€) based on official national price lists for public hospitals and the HCRU estimates from the questionnaire.ResultsThe physician-estimated prevalence of AGW in Morocco was 1.6%-2.6% in women and 2.0%-5.3% in men. A mean (median) of 6.4 (4) patients per month per physician sought medical attention for AGW. Simple observation was the most common diagnostic method for AGW in both men and women, and excision was the most prescribed therapy (75%), requiring a mean of 2 visits. Recurrence occurred in approximately 27% of patients. The cost per case of managing AGW, including recurrence, was estimated at 2182-2872 MAD (€207-272) for women and 2170-2450 MAD (€206-233) for men. The total annual cost of medical consultations for AGW in Morocco ranged from 3,271,877 MAD to 4,253,703 MAD (€310,828-404,102).ConclusionsExpert consensus indicates that AGW represent a significant burden to the Moroccan public healthcare system. These data can inform policy makers regarding this vaccine-preventable disease.

Project description:ObjectiveTo generate estimates of comparative clinical effectiveness for interventions used in the treatment of anogenital warts (AGWs) through the systematic review, appraisal and synthesis of data from randomised controlled trials (RCTs).DesignSystematic review and network meta-analysis of RCTs. Search strategies were developed for MEDLINE, Embase, the Cochrane Library and the Web of Science. For electronic databases, searches were run from inception to March 2018. The systematic review was carried out following the general principles recommended in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.ParticipantsPeople aged ≥16 years with clinically diagnosed AGWs (irrespective of biopsy confirmation).InterventionsTopical and ablative treatments recommended by the British Association for Sexual Health and HIV for the treatment of AGWs, either as monotherapy or in combination versus each other.Outcome measuresComplete clearance of AGWs at the end of treatment and at other scheduled visits, and rate of recurrence.ResultsThirty-seven RCTs met inclusion criteria. Twenty studies were assessed as being at unclear risk of bias, with the remaining studies categorised as high risk of bias. Network meta-analysis indicates that, of the treatment options compared, carbon dioxide laser therapy is the most effective treatment for achieving complete clearance of AGWs at the end of treatment. Of patient-applied topical treatments, podophyllotoxin 0.5% solution was found to be the most effective at achieving complete clearance, and was associated with a statistically significant difference compared with imiquimod 5% cream and polyphenon E 10% ointment (p<0.05). Few data were available on recurrence of AGWs after complete clearance. Of the interventions evaluated, surgical excision was the most effective at minimising risk of recurrence.ConclusionOf the studies assessed, as a collective, the quality of the evidence is low. Few studies are available that evaluate treatment options versus each other.Trial registration numberCRD42013005457.
