Topical ivermectin

Rosacea has variable clinical presentation consisting of four overlapping phenotypes: erythematotelangiectatic, papulopustular, phymatous, and ocular.1 Rosacea's pathogenesis involves increased cutaneous density of Demodex folliculorum mites, which drive inflammation through activation of Toll-like receptor-2.1,2 Thus, topical ivermectin (IVM) 1.0% cream's anti-inflammatory and acaricidal activity provides an effective and targeted treatment for moderate-to-severe rosacea. However, literature assessing IVM is limited to efficacy in treating the papulopustular presentation, limiting generalizability...

PURPOSE: To determine the association between ocular and facial demodicosis, and the effect of facial treatment on ocular demodicosis. DESIGN: Prospective clinical cohort study. METHODS: Ocular demodicosis outpatients from a tertiary medical center were enrolled from April to December 2020. The diagnosis was based on epilation of four eyelashes from each upper eyelid. High ocular Demodex load (ODL) was defined as ≥8 mites per eye. Facial infestation was assessed by direct microscopic examination, with facial Demodex overgrowth (FDO) defined as a density >5 mites/cm2 ...

The increasing resistance to antiparasitic drugs and limited availability of new agents highlight the need to improve the efficacy of existing treatments. Ivermectin (IVM) is commonly used for parasite treatment in humans and animals, however its efficacy is not optimal and the emergence of IVM-resistant parasites presents a challenge. In this context, the physico-chemical characteristics of IVM were modified by nanocrystallization to improve its equilibrium water-solubility and skin penetration, potentially improving its therapeutic effectiveness when applied topically...

DESCRIPTION: Evidence for the use of outpatient treatments in adults with confirmed COVID-19 continues to evolve with new data. This is version 2 of the American College of Physicians (ACP) living, rapid practice points focusing on 22 outpatient treatments for COVID-19, specifically addressing the dominant SARS-CoV-2 Omicron variant. METHODS: The Population Health and Medical Science Committee (formerly the Scientific Medical Policy Committee) developed this version of the living, rapid practice points on the basis of a living, rapid review done by the ACP Center for Evidence Reviews at Cochrane Austria at the University for Continuing Education Krems (Danube University Krems)...

Although rejected by the World Health Organization, the human and even veterinary formulation of ivermectin has widely been used for prevention and treatment of COVID-19. In this work we leverage Twitter to understand the reasons for the drug use from ivermectin supporters, their source of information, their emotions, their gender demographics, and location information, in Nigeria and South Africa. Topic modelling is performed on a Twitter dataset gathered using keywords 'ivermectin' and 'ivm'. A model is fine-tuned on RoBERTa to find the stance of the tweets...

The current study investigated the scabicidal potential of Egyptian mandarin peel oil (Citrus reticulata Blanco, F. Rutaceae) against sarcoptic mange-in-rabbits. Analysis of the oil's GC-MS identified a total of 20 compounds, accounting for 98.91% of all compounds found. Mandarin peel oil topical application improved all signs of infection, causing a scabicidal effect three days later, whereas in vitro application caused complete mite mortality one day later. In comparison to ivermectin, histopathological analysis showed that the epidermis' inflammatory-infiltration/hyperkeratosis-had disappeared...

BACKGROUND: Treatment failure is considered to be an important factor in relation to the increase in scabies incidence over the last decade. However, the regional and temporal differences, in addition to the predictors of therapy failure, are unclear. OBJECTIVES: We aimed to conduct a systematic review of the prevalence of treatment failure in patients with scabies and investigation of associated factors. METHODS: We searched MEDLINE, EMBASE, CINAHL, Web of Science, Scopus, Global Health and the Cochrane Central Register of Controlled Trials from inception to August 2021 for randomized and quasi-randomized trials, in addition to observational studies that enrolled children or adults diagnosed with confirmed or clinical scabies treated with permethrin, ivermectin, crotamiton, benzyl benzoate, malathion, sulfur or lindane, and measured treatment failure or factors associated with treatment failure...

BACKGROUND: Increasing evidence has sparked a debate on the loss of sensitivity of scabies mites to conventional permethrin therapy. Mutations in the voltage-sensitive sodium channels (VSSC) were associated with knockdown resistance (kdr) in many arthropods, but have never been identified in Sarcoptes scabiei variatio hominis mites. OBJECTIVES: To identify factors contributing to therapy failure. METHODS: 67 mites were collected from 64 scabies-infested patients in Vienna, Austria, of whom 85...

Background: Antibiotics are considered the backbone of rosacea management, especially for controlling inflammatory papules and pustules. We aim to evaluate the efficacy and safety of varied prescriptions and doses of antibiotics in treating rosacea by network meta-analysis. Methods: In this study, we compared all available randomized controlled trials (RCTs) that have studied systemic and topical antibiotics and placebo in rosacea therapy. We searched databases such as the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, PubMed, Web of Science, and LILACS for published and unpublished RCTs on ClinicalTrials...

The Australian sea lion ( Neophoca cinerea ) experiences high pup mortality of seasonally alternating severity, partly attributed to endemic hookworm ( Uncinaria sanguinis ) infection. To further explore health outcomes of early hookworm elimination, a treatment trial was conducted at Seal Bay Conservation Park, South Australia, over consecutive lower and higher mortality breeding seasons (2019, 19.2%; 2020-1; 28.9%). Pups ( n = 322) were stratified into two age cohorts (median 14 d and 24 d recruitment ages) and randomly assigned to treated (topical ivermectin 500  μg/kg) or control (untreated) groups...

Demodex folliculorum is a commensal mite that inhabits the orifices of cutaneous pilosebaceous follicles. Overgrowth of these organisms can lead to Demodex folliculitis, which typically presents as papules and pustules predominantly involving the temples, cheeks, and occasionally the chest. We present a 51-year-old woman with iatrogenic Demodex folliculitis secondary to immunosuppressive treatment for an autoimmune connective tissue disease. Histopathological exam of a skin biopsy, which revealed follicular Demodex mites, confirmed the diagnosis...

Oral myiasis is a rare parasitic disease that requires immediate treatment once diagnosed. However, no standard treatment protocol can be found in the literature. Through a clinical-surgical report, we present the case of an 82-year-old man with lesions extending through the vestibule and alveolar ridge of the maxilla on both sides, in addition to occupying a large part of the palate, with a considerable number of larvae. The patient was initially treated with a single dose of systemic ivermectin (6 mg orally) and topical application of a tampon soaked in ether...

Ivermectin was popular drug on trial for preventive and therapeutic role in COVID-19. However, there is disagreement concerning the validity of its clinical efficacy. Hence, we conducted a Meta-analysis and Systematic review for effect of Ivermectin Prophylaxis in prevention of COVID-19. The online databases of PubMed (Central), Medline, and Google scholar for randomized controlled trials, non-randomized trial and prospective cohort study were searched up to March 2021. Nine studies were included for analysis, out of which four were Randomized controlled Trial (RCTs), Two Non-RCTs and three cohort studies...

Scabies is a parasitic skin disease caused by Sarcoptes scabiei var. hominis . Crusted scabies, also known as Norwegian scabies, is a rare and severe form of scabies that occurs more frequently in immunocompromised, elderly, disabled, and debilitated patients. The present study reports a case of crusted scabies combined with bullous scabies. A 44-year-old man was admitted with the chief complaint of red, thick, scaly patches of skin accompanied by crusting that felt itchy and worsened at night. The lesions had appeared all over his body intermittently for the last 10 years; however, the complaints worsened in the last 2 months...

PURPOSE: To describe a case of bilateral facultative ophthalmomyiasis externa due to Calliphoridae in a 30-year-old male assault victim at a suburban hospital in New York and review the relevant literature. OBSERVATIONS: An adult male was found to have maggot infestation of both eyes and severe secondary injury to the left cornea and ocular surface. He was treated with manual larvae removal, oral ivermectin, broad spectrum IV antibiotics, and topical antibiotics...

BACKGROUND: Residual malaria transmission is the result of adaptive mosquito behavior that allows malaria vectors to thrive and sustain transmission in the presence of good access to bed nets or insecticide residual spraying. These behaviors include crepuscular and outdoor feeding as well as intermittent feeding upon livestock. Ivermectin is a broadly used antiparasitic drug that kills mosquitoes feeding on a treated subject for a dose-dependent period. Mass drug administration with ivermectin has been proposed as a complementary strategy to reduce malaria transmission...

BACKGROUND: Hematophagous mites affect numerous bird species, causing severe injuries to the budgerigars. Some species can cause dermatitis in humans. AIMS: The purpose was to morphologically identify the mites related to budgerigars ( Melopsittacus undulatus) and their nests in Yucatan, Mexico. METHODS: In May 2022, a private budgerigar hatchery was visited and mites were collected from the bodies of the birds and their nests. The morphological traits of the mites were confirmed by scanning electron microscopy...

Scabies is an invasive skin condition caused by Sarcoptes scabiei mites. The present study investigates the antiscabies potential of coconut seed extract (CSE) in rabbits. GC-MS analysis of the seed oil identified 17 known compounds, while CSE phytochemical investigation afforded 4 known ones. The topical application of seed extract improved all signs of infection, and the improvement started 3 days post application. However, in vitro application of the extract caused 99% mortality of mites 1 day post application...

INTRODUCTION: Topical ivermectin is an anti-inflammatory and anti-Demodex drug for papulopustular rosacea. Rosacea is a relapsing disease and the time between recurrences should be considered alongside efficacy. OBJECTIVES: The aims of this study were to assess the time of first relapse and relapse rates of Demodex mite infestation and papulopustular rosacea. METHODS: We conducted a prospective study of subjects affected by different degrees of papulopustular rosacea...

Pharmaceutical messianism is a manifestation of medical populism. It arises during extraordinary crises, is built on the familiar, endorsed by heterodox authorities, and involves a highly accessible panacea. Amid the politics and public desperation in the Philippines during the COVID-19 pandemic, pharmaceutical messianism can be observed in the form of Ivermectin, a panacea offered to prevent and treat COVID-19. Thus, it may be worthwhile to determine the changes and patterns of public interest toward Ivermectin...
