The parasites of genus Leishmania are the causative agents of one of the most widespread and devastating diseases. According to follow-up data, these medications may provoke adverse drug reactions, drug resistance, relapse as well as financial burden. The mechanism of action of opioid drugs are primarily exerted via transmembrane G-protein coupled receptors. One of the potent synthetic immunomo...

The low-molecular-weight imidazoquinolinamine derivative, l-(2methylpropyl)-l//-iinidazo(4,5-<')quinolin-4-amine (imiquimod, previ ously described as R-837), induced a-interferon (IFN-a) in mice. IFN induction was identified at oral doses as low as 3 mg/kg. The 10% lethal dose for daily treatment with imiquimod was 200 mg/kg. Oral treatment with 30 mg/kg imiquimod once every three days signific...

N oninvasive immunobiologic therapy with topical imiquimod, 5%, cream is an emerging therapeutic option for basal cell carcinoma (BCC). Despite the documented short-term efficacy of imiquimod for superficial BCC, few data exist on the longterm course of imiquimod-treated BCCs. In an effort to evaluate the long-term outcome of patients treated with imiquimod for BCC, we conducted a 5-year follow...

BACKGROUND The immune system plays a critical role in the development and pathogenesis of actinic keratosis (AK). Imiquimod has been shown to stimulate the cutaneous immune response and be effective for the treatment of nonmelanoma skin cancers. OBJECTIVE Two phase III, randomized, double-blind, vehicle-controlled studies evaluated the efficacy of imiquimod 5% cream compared with vehicle in t...

Imiquimod activates the immune system when applied to a local area. We report a patient with a history of well-controlled myasthenia gravis who was prescribed imiquimod for lentigo maligna. Treatment was halted after 2 weeks when the patient reported itching and irritating sensations in his throat, consistent with previous myasthenia exacerbations. The symptoms improved once imiquimod use was d...

The survival of the Tasmanian devil (Sarcophilus harrisii) is threatened by devil facial tumour disease (DFTD). This transmissible cancer is usually fatal, and no successful treatments have been developed. In human studies, the small immunomodulatory molecule imiquimod is a successful immunotherapy, activating anti-tumour immunity via stimulation of toll-like receptor-7 (TLR7) signaling pathway...

Imiquimod, an immunomodulator with no direct in vitro antiviral activity, has in vivo anti-herpesvirus activity by inducing interferon and enhancing other only partially defined immune responses. Imiquimod treatment of primary genital herpes simplex virus (HSV) infection in guinea pigs reduces the level of genital disease by 90%. We further investigated its utility as suppressive therapy of rec...

BACKGROUND AND OBJECTIVE The objective of this study was to improve port wine stain (PWS) therapeutic outcome in response to laser therapy. Our specific aim was to determine whether the combined use of pulsed dye laser (PDL) therapy and topical Imiquimod versus PDL alone can improve PWS therapeutic outcome. STUDY DESIGN/MATERIALS AND METHODS This pilot study involved a retrospective review of...

BACKGROUND Topical imiquimod is sometimes used for lentigo maligna (LM) in situ melanoma instead of surgery, but frequency of cure is uncertain. Pathological complete regression (pCR) is a logical surrogate marker for cure after imiquimod, although residual LM and atypical melanocytic hyperplasia may not be reliably distinguished. A trial comparing imiquimod vs. surgery might be justified by a ...

The pathogenesis of vitiligo was examined for clues to the pigmentary changes that may occur after treatment with topical imiquimod. The literature varies on the pigmentary changes induced by topical use of imiquimod. The US Food and Drugs Administration lists 68 reports of pigmentary changes out of a total of 1257 reports related to imiquimod lodged from 1997 to 2003. Some studies describe vit...
