BACKGROUND In patients with actinic keratosis (AK), subclinical and clinical lesions coexist across large areas of sun-exposed skin. The long-term efficacy of AK treatments depends on their ability to eradicate both types of lesions across the entire field. OBJECTIVE To assess the long-term efficacy of imiquimod 3.75% using the reduction in lesions from Lmax (maximum lesion count during treat...

TO THE EDITOR: The role of Toll-like receptor-7s (TLR7) in innate immunity against single-stranded RNA viruses is well established. Recently, our group found TLR7 agonists also relax guinea pig and human airway smooth muscle strips via production of nitric oxide (1, 2). Immunostaining identified extensive TLR7 expression on airway nerves, but none on smooth muscle; thus we hypothesized airway n...

We have provided evidence for a multifaceted antitumor-function of the Toll-like receptor 7 (TLR7) agonist imiquimod, which rapidly recruits plasmacytoid dendritic cells and possibly other immune cells into tumors by inducing the secretion of CCL2 by dermal cells. Imiquimod induces pDC maturation and their conversion into cytolytic killer cells, which are capable of eliminating tumors independe...

SUMMARY We present a brief literature review of the topical immune-modulating medication Imiquimod. The treatment of periorbital melanoma in situ typically requires surgical resection. Here we discuss a case of lower eyelid melanoma in situ successfully treated non-operatively with Imiquimod.

Mycosis fungoides (MF) and S é zary syndrome (SS) are the most common forms of cutaneous T cell lymphoma (CTCL), and most frequently manifest as CD4 CD45RO malignant T cells with T cell receptor clonality [1]. MF and SS are often refractory to standard chemotherapeutic treatments, which expose patients to toxicity often without substantial benefi t. Because of the limited effi cacy of existing ...

BACKGROUND Transcutaneous immunization (TCI) approaches utilize skin associated lymphatic tissues to elicit specific immune responses. In this context, the imidazoquinoline derivative imiquimod formulated in Aldara applied onto intact skin together with a cytotoxic T lymphocyte (CTL) epitope induces potent CTL responses. However, the feasibility and efficacy of the commercial imiquimod formulat...

Topical imiquimod cream is increasingly applied in the treatment of lentigo maligna (LM), in particular for large lesions where surgery may lead to disfiguring scars. Published studies suggest that more frequent and prolonged treatment with topical imiquimod is associated with higher efficacy. In this study we prospectively treated 27 patients suffering from LM on the face with imiquimod 5% cre...

The treatment of melanoma in situ (MIS) is controversial with current standard of care being surgical excision with clear margins. Alternative topical therapy with imiquimod has been proposed in recent studies as a possible treatment for MIS. This study aimed to evaluate the use of topical 5% imiquimod as an alternative approach for the treatment of residual melanoma in situ after surgical rese...

OBJECTIVE To evaluate the treatment of anal intraepithelial neoplasia (AIN) with the local immune response modifier imiquimod in human immunodeficiency virus (HIV)-positive men who have sex with men (MSM). DESIGN Prospective, nonrandomized, open-label pilot study, with a mean follow-up time of 9(1/2) months. SETTING Dermatology department of a university hospital. Patients Twenty-eight cons...

PURPOSE Women infected with human papillomavirus (HPV) with normal cytology to mild abnormalities currently have no treatment options other than watchful waiting or surgery if high-grade cervical lesions or cancer develop. A therapeutic vaccine would offer the possibility of preventing high-grade lesions in HPV-infected women. GTL001 is a therapeutic vaccine composed of recombinant HPV16 and HP...
