: Toxocariasis is a common zoonosis caused by infection with Toxocara canis or cati larvae. Ocular toxocariasis is one of the forms of infestation found in 1/1,000 - 1/10,000 children. Children with idiopathic nephrotic syndrome (INS) are at high risk of infections, also parasitic infestations, which can, in turn, cause relapses of the disease. A CASE REPORT: We present a case of a 6-year-old boy with steroiddependent nephrotic syndrome. The disease started at age of 2, the boy had 9 relapses of INS, and was treated with oral prednisone, levamisole, and cyclophosphamide...

Cutaneous and genital warts are common dermatological conditions caused by the human papilloma virus (HPV). Although it is a benign condition, it causes disfigurement, has a tendency to koebnerize, and can be transmitted to others. This makes adequate and timely treatment important. There are several conventional treatments available with variable response. Topical and systemic immunotherapy has now found a significant place in the treatment of warts because of its nondestructive action, ease of use, and promising results...

The fast anthelmintic resistance development has shown a limited efficiency in the control of animal's endoparasitosis and has promoted research using alternative control methods. The use of chemicals in animal anthelmintic treatment, in association with nematophagous fungi used for biological control, is a strategy that has proven to be effective in reducing the nematode population density in farm animals. This study aims to verify the in vitro susceptibility of the nematophagous fungi Arthrobotrys oligospora, Duddingtonia flagrans and Paecilomyces lilacinus against the antiparasitic drugs albendazole, thiabendazole, ivermectin, levamisole and closantel by using the Minimum Inhibitory Concentration (MIC)...

Haemonchus contortus is an important gastrointestinal parasite on sheep farms in tropical regions. The resistance of the parasite against most anthelmintic drugs represents a great economic problem to sheep farming and is a major challenge that needs to be overcome. The searches for new anthelmintic agents that act on different stages of the parasite's life cycle are necessary for the development of new therapeutic options. The aim of this study was to evaluate the in vitro and in vivo anthelmintic activity of Thymus vulgaris essential oil against H...

In Ontario, Canada, widespread resistance to ivermectin and fenbendazole, the only readily available ovine anthelmintics, has been documented, primarily in Haemonchus sp. In other parts of the world, closantel has been used to control such infections; however, the drug was not currently licensed for use in Canada and the USA. A randomized controlled trial was conducted on six client-owned farms in Ontario in 2013 and 2014 to determine the efficacy of closantel (Flukiver(®) 5% Oral Suspension, Elanco Animal Health, 10mg/kg bodyweight) against ivermectin- and fenbendazole-resistant Haemonchus sp...

Early in 2015, sheep in a summer rainfall area of NSW, Australia, displayed signs of haemonchosis despite treatment with monepantel. A faecal egg count reduction test (FECRT) was performed on yearlings with natural field infections using various anthelmintics. Only a four-way combination drench achieved a reduction in faecal egg count (FEC) greater than 95%. The combination contained abamectin, albendazole, levamisole and closantel. Treatments with a derquantel/abamectin combination, monepantel and moxidectin reduced FECs by 93, 31, and 30% respectively...

BACKGROUND: There is some evidence that ATP binding cassette (ABC) transporters play a role in resistance to anthelmintics, particularly against macrocyclic lactones. Some anthelmintics, including ivermectin (IVM), have been shown to induce transcription of multiple ABC transporters in nematodes; however, the effects of monepantel (MPL) on transcription of these transporter genes has not been studied. METHODS: Larvae of two MPL-susceptible isolates of Haemonchus contortus were exposed to MPL at two concentrations (2...

Levamisole is an immunomodulatory drug that was previously used to treat various medical conditions, including parasitic infections, nephrotic syndrome, and colorectal cancer. Over the last few years, increasing amounts of levamisole have been used as an adulterant in cocaine. Levamisole-cut cocaine has become a concern because it is known to cause a necrotizing purpuric rash, autoantibody production, and life-threatening leukopenia. Mixed histologic findings of vasculitis and thrombosis are characteristic of levamisole-induced purpura...

Levamisole is an increasingly common cocaine adulterant that can cause severe and rapid onset cutaneous vasculitis in humans. While most cases may be managed conservatively, we describe a series of patients in whom the extent of skin and soft tissue necrosis mandated surgical intervention. A retrospective review of all patients admitted to one of two regional burn centers between 2006 and 2016 for soft tissue necrosis after exposure to levamisole-adulterated cocaine was included in our study. Ten patients, majority female (9/10) with an average age of 43...

Gastrointestinal nemathelminths affect productive as well as reproductive performance of a wide range of ruminants. To assess the impact of anthelmintic treatment on gain in body weight (b. wt.) of sheep and goat, a study was conducted using two different flocks of sheep and goats each maintained in semi intensive system. Infected animals in both the flocks were divided into three groups each. Group I and II in each flock were treated with levamisole (@7.5 mg/kg b. wt. subcutaneously) and fenbendazole (@5 mg/kg b...

Because of developing resistance to the existing anthelmintic drugs, there is a need for new anthelmintic agents. Tobacco plant has alkaloid materials that have antiparasitic effect. We investigated the in vitro anthelminthic effect of aqueous and alcoholic extract of Tobacco (Nicotiana tabacum) against M. marshalli. For investigating this effect, we prepared three dilutions of aqueous and alcoholic extract of Tobacco (25, 50 and 75 mg/ml). The worms exposed to extracts for 10 h at 25-30 °C. The buffer PBS used as negative control and 50 mg/ml dilution of Levamisole used as standard reference...

PURPOSE: Luminal A breast cancers have better prognosis than other molecular subtypes. Luminal A cancers may also be insensitive to adjuvant chemotherapy, although there is little high level evidence to confirm this concept. The primary hypothesis in this formal prospective-retrospective analysis was to assess interaction between subtype (Luminal A vs. other) and treatment (chemotherapy vs. not) for the primary endpoint (10-year invasive disease free survival) of a breast cancer trial randomizing women to adjuvant chemotherapy, analyzed in multivariate Cox proportional hazards models using the Wald interaction test...

The metabolic disease, type 2 diabetes mellitus (T2DM), is a major risk factor for Alzheimer's disease (AD). This suggests that drugs such as metformin that are used to treat T2DM may also be therapeutic toward AD and indicates an interaction between AD and energy metabolism. In this study, we have investigated the effects of metformin and another T2DM drug, 5-aminoimidazole-4-carboxamide ribonucleotide (AICAR) in C. elegans expressing human Aβ42. We found that Aβ expressed in muscle inhibited levamisole sensitive nicotinic acetylcholine receptors and that metformin delayed Aβ-linked paralysis and improved acetylcholine neurotransmission in these animals...

Levamisole is an antihelminthic drug banned by the US Food and Drug Administration (FDA) in 2000 because of its dangerous side effects. Over the past few years, it has been identified as an adulterant in cocaine and reported to cause cutaneous vasculitis in cocaine users. The health burden of levamisole is serious since it is estimated that over 5 million Americans use cocaine and that 70% of the cocaine used in the USA contains levamisole. In this paper we report the case of a 23-year-old female cocaine user that presented with purpuric rash and skin necrosis, found to have positive c-ANCA and anti-proteinase 3 antibodies...

In phase I, faecal egg count reduction tests (FECRT) were conducted on six commercial cattle farms to compare the performance of two pour-on and one oral combination anthelmintic. Groups of 12-15 calves were sampled for faecal nematode egg count (FEC) before treatment with either abamectin oral, levamisole oral, an abamectin+levamisole oral combination or one of two abamectin+levamisole combination pour-ons. Samples were collected again 14days after treatment to calculate the percentage reduction in FEC. The proportions of infective stage larvae (L3) in faecal cultures were used to apportion egg counts to, and calculate efficacy against, the main parasite genera...

Levamisole, which is used as an adulterated compound of cocaine, is currently being seen year after year in cocaine intoxication. For a few cases in the last decade, necrotic purpura and neutropenia after levamisole/cocaine intoxication have been described in the medical community. Herein, we present an original case of levamisole intoxication of a 40-year-old woman who smoked heroin and cocaine few during a month. She rapidly presented an extensive necrotic purpura of the nose, cheeks and extremities (lower and upper), and immunologic reactions (positive anti-MPO and anti-HNE)...

Levamisole (LEVA) and garlic are prevalent immunomodulators in humans and animals. Therefore, the present study aimed to examine the immunomodulatory effects of LEVA and garlic oil (GO) alone or in combination on the immune response of Wistar rats. A total of 24 male Wistar rats were allocated into four equal groups: Control group, which was given ad libitum access to food and water; and groups 2‑4, which were orally administered LEVA [2.5 mg/kg body weight (BW) every 2 days], GO, (5 ml/kg BW daily), or LEVA plus GO, respectively for 4 consecutive weeks...

A combination of lipophilic and hydrophilic drugs in a single solution is a challenge due to their different physicochemical properties. In vitro and in vivo release studies are useful to optimize this solution. The in vitro (Franz diffusion cell) release rate of levamisole phosphate from an isotropic vehicle of medium chain mono and diglycerides (MCMDG) was significantly slower than the release from water. The injectable solution of the isotropic MCMDG-based system was prepared with 13.65% of levamisole phosphate and 0...

Helminth parasites rely on fast-synaptic transmission in their neuromusculature to experience the outside world and respond to it. Acetylcholine plays a pivotal role in this and its receptors are targeted by a wide variety of both natural and synthetic compounds used in human health and for the control of parasitic disease. The model, Caenorhabditis elegans is characterized by a large number of acetylcholine receptor subunit genes, a feature shared across the nematodes. This dynamic family is characterized by both gene duplication and loss between species...
