HPV-associated anal lesions in HIV+ patients: long-term results regarding quality of life.

PURPOSE: HIV infection and concomitant HPV-associated anal lesions may significantly impact on patients' quality of life (QoL), as they are predicted to have negative effects on health, psyche, and sexuality. MATERIAL AND METHODS: Fifty-two HIV+ patients with HPV-associated anal lesions were enrolled in a survey approach after undergoing routine proctologic assessment and therapy for HPV-associated anal lesions if indicated over a time span of 11 years (11/2004-11/2015). Therapy consisted of surgical ablation and topic treatment. QoL was analyzed using the SF-36 and the CECA questionnaires. RESULTS: Fifty-two of 67 patients (77.6%) were successfully contacted and 29/52 provided full information. The mean age was 43.8 ± 12.8 years. The median follow-up from treatment to answering of the questionnaire was 34 months. Twenty-one percent (6/29) of the patients reported suffering from recurrence of condyloma acuminata, three patients from anal dysplasia (10.3%). In the SF-36, HIV+ patients did not rate their QoL as significantly different over all items after successful treatment of HPV-associated anal lesions. In the CECA questionnaire, patients with persisting HPV-associated anal lesions reported significantly higher emotional stress levels and disturbance of everyday life compared to patients who had successful treatment (71.9/100 ± 18.7 vs. 40.00/100 ± 27.4, p = 0.004). Importantly, the sexuality of patients with anal lesions was significantly impaired (59.8/100 ± 30.8 vs. 27.5/100 ± 12.2, p = 0.032). CONCLUSION: HPV-associated anal lesions impact significantly negative on QoL in HIV+ patients. Successful treatment of HPV-associated anal lesions in HIV+ patients improved QoL. Specific questionnaires, such as CECA, seem to be more adequate than the SF-36 in this setting.

[Treatment of HPV-associated Anal Lesions in HIV-positive Patients - Comparison of Surgical Treatment and Topical Therapy with Imiquimod]. / Behandlung HPV-assoziierter analer Läsionen bei HIV-positiven Patienten ­ chirurgische Abtragung vs. topische Therapie mit Imiquimod.

OBJECTIVES: In HIV+-patients, routine proctological assessment is warranted due to the high incidence of human papilloma virus (HPV) infection-related anogenital lesions, such as Condylomata acuminata (C. ac.), anal intraepithelial dysplasia (AIN) and anal cancer. For C. ac. and AIN, surgical resection and topical therapy with imiquimod have been discussed as treatment options. BACKGROUND: In this study, we contrasted surgical resection and topical imiquimod therapy of HPV-associated anal lesions in HIV+-patients, with a focus on healing rates and clinical outcome. We also analysed whether a synergistic treatment effect was detectable. METHODS: This was a retrospective analysis of 97 HIV+ patients who underwent proctological evaluation and treatment over a 10-year period (11/2004 - 11/2015) at our centre. Initial success of surgical treatment, topical imiquimod therapy and the combination of the two strategies were compared. RESULTS: In 53/97 patients (54%), HPV-associated anal disease was diagnosed upon the first visit. In approx. 50% of the patients, the HIV infection was adequately controlled (52 patients with viral load < 40 copies [53.6%]) under cART. The mean age was 41.0 ± 11.6 years. In 7/53 patients with macroscopic C. ac., low-grade and in 18/53 patients high-grade AIN were additionally confirmed. Success rates of surgical resection, imiquimod treatment and the combination of the two were compared. Complete remission of C. ac. and AIN four weeks after treatment was considered a therapeutic success. For C. ac., success rates with imiquimod were 5/25 (20.0%) vs. surgery* 30/57 (52.6%, Mann-Whitney U test p < 0.05) vs. surgery+imiquimod 7/15 (46.7%). For AIN, success rates with imiquimod were 4/24 (16.7%) vs. surgery* 47/83 (56.7%, Mann-Whitney U test p < 0.05) vs. surgery+imiquimod 9/21 (42.8%). In 7/92 (13%) of surgical treatments, complications were reported: four minor and two significant bleeding episodes and one perianal thrombosis. No side effects of imiquimod were documented besides skin irritation. CONCLUSION: Surgery is more effective than topical imiquimod as initial therapy of HPV-related anogenital disease in HIV+-patients. A synergistic effect could not be demonstrated. On this basis, we recommend surgical treatment of C. ac. and AIN in HIV+-patients as first line treatment.
