Filter by:Women included between 18 and 45 years old, pregnant during their second or third trimester of pregnancy (calculated by a sure menstrual date and confirmed by a 1st trimesteric ultrasound) with hemoglobin level below 10.5 mg /dL.
The goal of this study is to describe the prevalence and the type of parasite in patients with a chronic spontaneous urticaria as well as to describe the associations between parasitic disease and the characteristics of the patients, for example eosinophilia.
This is a single-centre, open-label, Phase Ib study designed to assess if intravenous injection of approximately 3200 P. falciparum (NF54 strain) sporozoites can be safely administered to achieve blood-stage parasitaemia with a kinetics/PCR profile that will allow for the future characterisation of antimalarial blood-stage activity of new chemical entities in a relatively small number of participants during early drug development. Healthy, malaria-naïve adults, aged 18-55 years, will be enrolled in a maximum of 2 cohorts. Enrolment into the cohorts will proceed sequentially, with two target levels of parasitaemia, i.e., 5000 parasites/mL blood in Cohort 1 and 10000 parasites/mL blood in Cohort 2. (Based on observed levels of parasitaemia in Cohort 1, the target threshold for treatment in Cohort 2 was maintained at 5,000 p/mL (vs 10,000 p/mL in the protocol)). The 3-day antimalarial therapy regimen will be further administered and monitored until parasite clearance. Safety and tolerability will be monitored during the whole study duration.
Demodex blepharitis is a prevalent cause of comorbid infection among individuals undergoing cataract surgery. Several complications may arise in the postsurgical period from Staphylococcus or Streptococcus co-infections, as Demodex is a vector for these pathogens. Hence, prophylactic treatments before cataract surgery may lead to a reduction in complication rates. Since Demodex infestation and cataract surgery are two prevalent coexisting conditions in the general population, this study aims to test the effect of four combined treatments to eradicate or improve the Demodex infestation index before surgery. The investigators are conducting a single-blinded randomized trial of four therapies in participants undergoing cataract surgery. All participants will or are receiving daily eyelid cleansing bid and topical 0.3% ciprofloxacin q4h for three days added to the allocated treatment arm. Our four intervention groups are: [1] Blephaclean eye scrubs; [2] 50% dilution baby shampoo; [3] tea tree oil shampoo; [4]: topical 0.3% ciprofloxacin alone. To assess treatment efficacy, the investigators will perform eyelash hair epilation pre and postoperatively. The primary outcome is a change in the mean Demodex spp. infestation index. Also, a change in the crude number of Demodex (egg, larvae, nymph, or adult-form) spp. in eyelashes after one-week of therapy.
A health education learning package (HELP) has been improved and evaluated for its impact against intestinal parasitic infections among Orang Asli schoolchildren in West Malaysia. 13 schools were allocated into two groups (intervention and control groups) and the impact of HELP was evaluated after 3 and 6 months of baseline assessment and HELP intervention.
The goal of the proposed study is to assess the prevalence of intestinal parasitic diseases in adults and children. These invasions are included to "dirty hand diseases" (per os invasions), therefore it applies mainly preschool children.
This is a randomized, double-blind, placebo-controlled clinical study evaluating the efficacy and safety of a single application of 0.5% ivermectin lotion in Filipino subjects with head lice.
The aim of this study is to estimate the accuracy of CL Detect Rapid Test™ compared to a composite reference standard test (Direct examination of skin smears + PCR test) in patients with clinically suspected Cutaneous Leishmaniasis disease in Morocco.
The IDIS study aims to develop a new rapid diagnostic test for invasive salmonellosis using samples (blood, urine) collected from patients with fever and healthy controls at the Institute of Tropical Medicine (ITM) and collaborating centers. The samples are collected after informed consent and/or assent is given by the participant and are stored in a -80 ⁰C freezer after processing (centrifugation and/or aliquoting). Basic information regarding the patient and the samples are coded and stored in a protected Microsoft Access database. The samples will be shipped to Belgium for proteomic analysis. Identification of Salmonella specific proteins in the samples will hopefully support the development of a rapid diagnostic test. Once this test has been developed, the samples will also be used for validation and evaluation of this test.
Antimalarial drug resistance has reached critical levels on the Thai-Cambodian border. Many have begun advocating for concerted malaria elimination efforts in Cambodia. However, there is currently no consensus on how malaria elimination is to be achieved with the tools available. In this study, the investigators will conduct operational research with the Royal Cambodian Armed Forces (RCAF) and National Malaria Center (CNM) to quantify the relative effectiveness of the two major interventional approaches - monthly malaria prophylaxis (MMP) or focused screening and treatment (FSAT) - in a head to-head comparison. In addition, the investigators will quantify the relative contribution of a recently advocated vector intervention for military personnel - the insecticide treated uniform (ITU) - in addition to other vector control measures currently employed by the RCAF. The investigators will employ the same permethrin insecticide self-application kits currently used by the US military. The investigators will estimate the cost effectiveness of each approach and attempt to define the best way forward for malaria elimination efforts in a critically important malaria reservoir in military population (and their dependents) who reside on the Thai-Cambodian border. The aim of the study is not only to conduct research to better define the best way forward in malaria elimination efforts in the high risk military populations, but to also build capacity within the RCAF to support and lead future elimination efforts in the most difficult-to-reach mobile populations.
