P76 Management of aciclovir-resistant mucocutaneous herpes simplex virus infection: a systematic review
British Journal of Dermatology(2023)
摘要
Abstract Aciclovir resistance results in immunocompromised hosts due to long-term antiviral therapy and ongoing viral replication. Aciclovir resistance in herpes simplex virus (HSV) poses a major concern, as this can lead to chronic and recalcitrant infection that significantly impacts on the quality of life. While different treatment options exist, there are currently no standardized clinical treatment guidelines for mucocutaneous aciclovir-resistant (ACV-R) HSV infection. This systematic review seeks to identify safe and effective treatments for mucocutaneous ACV-R HSV infection. For this systematic review, PubMed/MEDLINE and Embase were searched in September 2022 for all articles published between 1 January 1980 and 1 September 2022. Studies were included if they described the use of a medication for the treatment of mucocutaneous ACV-R HSV infection. From the initial search that yielded 1066 studies, 86 met the inclusion criteria and were selected. Of the 86 studies, 6 were clinical trials and 80 were case reports/series. A total of 318 patients were included in our review. Foscarnet [intravenous (IV) and topical] was studied in 5 clinical trials and 25 case reports/series, leading to complete response in most patients, with adverse effects including renal toxicity and electrolyte abnormalities. Vidarabine (IV) was found to be inferior to foscarnet in a clinical trial and reported in two case reports. Common side-effects included nausea, anaemia and renal impairment. Trifluridine (topical) was studied in a clinical trial and a case report, showing complete response in some patients. Cidofovir (IV, topical, intralesional) was studied in 21 case reports/series, showing complete response in most patients, with renal impairment as the most common adverse effect. Imiquimod (topical) was studied in eight case reports/series, showing complete response and no side-effects. Pritelivir (oral) was reported in two case reports/series, showing complete response and no side-effects. Combination treatment was reported in 10 case reports/series with variable clinical response. Our review also identified reports of less widely used treatments. These include artesunate, zidovudine, varicella-zoster virus vaccine, leflunomide and surgical excision, which achieved variable response rates but have not been widely studied. While foscarnet and cidofovir have the most robust evidence, IV administration of these agents is associated with significant side-effects and may be limiting. Intralesional and topical formulations of cidofovir, trifluridine and imiquimod are alternative options appropriate for outpatient management. Pritelivir is a novel and promising treatment of mucocutaneous ACV-R HSV infection.
