Managing Monkeypox Virus: Characterizing Common Cutaneous Manifestations and Antiviral Efficacy.

BACKGROUND: The Monkeypox virus (MPX) has been detected in multiple non-endemic countries since May 2022. The cutaneous manifestations of MPX can have multiple distinct presentations, including pustular and vesicular. Although there are no approved treatments, three antivirals (brincidofovir, cidofovir, tecovirimat) have been utilized. The objective of our study was to conduct a systematic review to evaluate antiviral efficacy (first aim) and cutaneous manifestations of MPX (second aim). METHODS: Utilizing PRISMA guidelines, we searched PubMed and SCOPUS databases to identify studies utilizing antiviral treatment in human subjects for MPX and studies reporting cutaneous characteristics of MPX lesions. RESULTS: For our first aim, six articles met inclusion criteria. For our second aim, 27 met inclusion criteria. Eighty-eight percent had complete resolution with tecovirimat (n=28) which was well tolerated, and decreased hospitalization time (10 days) compared to brincidofovir (29 days). Forty-four percent of patients had <10 cutaneous lesions and 36% had 10-100 lesions. The most common lesion type was pustular (32%, n=380). CONCLUSION: This limited sample of studies suggests that tecovirimat is well tolerated and may be an effective antiviral for MPX treatment. Further studies are required to better understand the role of antivirals for MPX treatment among human patients. J Drugs Dermatol. 2023;22(3): doi:10.36849/JDD.7263.

Assessing Comparative Efficacy of Biologics for the Treatment of Psoriasis With Nail Involvement: A Systematic Review.

Background: Despite recent advances in biologics, there is a lack of significant evidence regarding the comparative efficacy of biologics in treating more resistant features of psoriasis, namely nail psoriasis. A systematic review synthesizing data from multiple studies is efficacious in assessing the comparative efficacy among biologics for the treatment of nail psoriasis. Objective: To evaluate and compare the efficacy of biologics for the treatment of nail psoriasis. Methods: Utilizing PRISMA guidelines, a systematic literature review was conducted using the Pubmed database on November 16, 2022. Studies selected were phase 3 or 4 randomized clinical trials, clinical studies, or other randomized trials with data on the treatment with biologics for adults with nail psoriasis. Results: Sixteen studies meeting inclusion criteria were included for analysis. At 24 weeks, the highest mean NAPSI percent improvement achieved at week 24 was by brodalumab (76.9%) followed by etanercept (74%) and ixekizumab (70.5%) while the biologics achieving the greatest proportion of NAPSI 0 were adalimumab (44.6%) and ixekizumab (41%). Conclusions: This study helps elucidate the comparative efficacy of biologics for the treatment of nail psoriasis. This review suggests that brodalumab and etanercept are associated with the highest percent improvement in nail psoriasis while adalimumab and ixekizumab are associated with the greatest probability of complete nail resolution.

Multiple Keratoacanthomas Following Moderna Messenger RNA-1273 COVID-19 Vaccination Resolved With 5-Fluorouracil Treatment: Case Report.

Cutaneous reactions have been commonly associated with the Moderna messenger RNA (mRNA) COVID-19 vaccine. Among the reported cutaneous side effects, there have not been any associations reported yet regarding keratoacanthoma development after COVID-19 mRNA vaccination. We report a novel case of an 86-year-old man who experienced an eruption of multiple keratoacanthomas 2 weeks after inoculation with the Moderna mRNA-1273 vaccine that resolved following treatment with intralesional 5-fluorouracil.
