Filter by:People of all ages are affected by intestinal parasitic infections(IPIs) ; however, children are the most commonly affected, which is linked to their poor hygienic practices, and weak immune status. In children, IPIs are associated with malabsorption, weight loss, anemia, poor growth rate, learning difficulties, mental retardation and intellectual problems . The difficulty of diagnosis is the main problem in the control of intestinal parasitic infections. The choice of a particular technique is usually influenced by affordability, simplicity, cost, sensitivity in addition to the level of technical skills involved. Microscopic examination remains the cornerstone of parasitological diagnosis which is time consuming and requires an experienced observer to identify the organism. Formalin-ether sedimentation technique is commonly used in laboratories owing to its ability to isolate a large variety of parasites. However, it's a labor intensive procedure and is usually associated with hazards of using the inflammable lipid solvents. The drawbacks of the previous techniques have encouraged the development of commercial products such as Feconomics which is a new ready to use kit for concentration of stool samples in parasitological diagnosis. The aim of the study is : evaluation of the efficacy of Feconomics technique in comparison to traditional techniques i.e., direct smear and formalin ethyl acetate sedimentation technique for the diagnosis of intestinal parasites in school children.
The overall goal of this study is to determine if periodic de-worming of persons living with HIV in intestinal parasite-endemic regions will lead to decreased morbidity and mortality associated with HIV by reducing immune activation and intestinal damage associated with these diseases. The hypothesis for this project is that intestinal parasitic infections contribute to a modifiable pro-inflammatory state in persons living with HIV (PLWH). Aim 1: Determine the prevalence of intestinal parasitic infections in PLWH receiving care at an HIV-treatment center in Lilongwe, Malawi using a highly sensitive multi-parallel stool PCR test. Hypothesis: highly sensitive stool PCR testing will demonstrate that disease burden of parasitic infection in PLWH in Malawi is higher than historically reported based on stool microscopy. Aim 2: Determine the impact of parasitic infection on intestinal damage and immune activation by measuring sCD14, sCD163, and intestinal fatty acid binding protein (I-FABP) in PLWH. Hypothesis: plasma biomarkers reflecting intestinal damage and immune activation are elevated in those with HIV and parasitic co-infection compared with parasite-negative participants with HIV. Aim 3: Determine the impact of eradication of parasitic infection on intestinal damage and immune activation by measuring sCD14, sCD163, and intestinal fatty acid binding protein (I-FABP) in PLWH before and after treatment of parasitic co-infection. Hypothesis: plasma biomarkers reflecting intestinal damage and immune activation are elevated in those with HIV and parasitic co-infection, and these biomarkers decrease with anti-parasitic treatment.
This is an open-label, adaptive study that will utilise the P. falciparum induced blood stage malaria (IBSM) model to characterise the pharmacokinetic/pharmacodynamic (PK/PD) profile of pyronaridine. Up to 18 healthy, malaria naïve adult participants are planned to be enrolled into this study, in cohorts of up to six participants each. Following a screening period of up to 28 days, cohorts of up to 6 healthy participants will be enrolled. Each participant will be inoculated intravenously on Day 0 with P. falciparum infected erythrocytes. Participants will be followed up daily on Days 1 to 3, and will attend the clinical unit once on Days 4, 5, 6 and 7 for clinical evaluation and blood sampling. Participants will be admitted to the clinical trial unit on Day 8 for a single oral dose of pyronaridine. Different doses of pyronaridine will be administered across and within cohorts. Participants will be randomised to a dose group on the day of dosing. The highest dose of pyronaridine administered will be no more than 720 mg; the lowest dose administered will be no less than 180 mg. Each subsequent cohort will be composed of up to 3 dose groups. The Safety Data Review Team (SDRT) will review all available safety and tolerability data from the previous cohort/s prior to inoculation of the next cohort. Participants will be confined in the clinical unit for at least 96 h (Days 8 - 12) to monitor the safety and tolerability of pyronaridine dosing. Upon discharge from the clinical unit participants will be monitored on an outpatient basis up to Day 50±2. Participants will receive compulsory antimalarial rescue treatment with Riamet® (artemether/lumefantrine) on Day 47±2 or earlier.
Patients with Demodex infestation of the eyelids will have the sleeves from both eyes cleaned off with microblepharoexfoliation. Afterwards, one eye will be randomly selected for treatment with topical ivermectin 1% cream. The treatment will be repeated on that eye 2 weeks later. Afterwards, the patients will present monthly for photographs of the eyelashes. The photographs will be reviewed by an ophthalmologist outside of our institution who will be blind to which eye was treated and independently grade the amount of sleeves in each eye. The follow-up will be for 6 months after the second treatment.
Nutritional status during pregnancy plays an important role in maternal health and birth outcomes. While few factors impacting nutritional status during pregnancy have been identified, studies of undernutrition in children have revealed a key role for the gut microbiome. Remarkably, studies examining the dynamics of the maternal gut microbiome before and during pregnancy and its impact on birth outcomes are limited. This study is being conducted to investigate how a mother's nutritional status and her gut microbiome during pregnancy contribute to the birth outcomes and health of her baby. The gut microbiome is the totality of microorganisms (e.g. bacteria, viruses, fungi) living in the gastrointestinal tract. This study will focus on married pregnant women 24 years and younger living in Matiari District in Pakistan. The focus is on younger women due to their vulnerability to undernutrition. Pregnant participants, and upon delivery, their newborns will be followed throughout pregnancy and for a year afterwards. Throughout this period, the investigators will collect stool samples, rectal swabs, blood samples, health assessments, nutritional and dietary assessments and birth/ labour details. The goal is to define the relationship between a mother's nutritional status and her microbiome dynamics during pregnancy and how they contribute to the birth outcomes and growth of her newborn. Investigators hypothesizes that alterations of the microbiota in the maternal gut (dysbiosis) is exacerbated by nutritional status or pathogen exposure during pregnancy. This impacts weight gain because of impaired nutrient absorption, and can lead to corresponding negative birth outcomes.
Malaria is a parasitic disease causing substantial morbidity and mortality globally. Malaria is a potentially severe and fatal disease in non-immune individuals. In areas of intense transmission infections individuals acquired immunity that protect against clinical disease. Nonetheless, immunity is not regarding sterilizing and repeated infections often result in an asymptomatic carriage of malaria parasites. These chronic apparently asymptomatic infections have been associated with anemia, cognitive dysfunction and adverse events during pregnancy. Global migration has increased over the last decade and has resulted in an increasing number of migrants from malaria endemic regions arriving in non-endemic countries. Migrants from malaria endemic countries may carry asymptomatic infections with malaria parasites, as well as other parasitic infections such as strongyloides and schistosomiasis, with a possible negative impact on health in this group. The prevalence of asymptomatic malaria and other parasites is not fully elucidated in migrants from different regions. Moreover, the longevity of asymptomatic carriage of malaria parasites in absence of re-exposure is not known. The aim of this study is to assess the prevalence of malaria parasites and other parasitic infections in migrants in Sweden, both newly arrived and migrants with longer residency, and intend to evaluate the need for screening for various parasitic infections in migrants arriving in Sweden. Moreover, this study will also assess antibody responses to malaria and other parasitic diseases.

Role of parasitic infection in Inflammatory bowel disease and Irritable bowel The burden of the parasitic disease is in-direct relation with the health and nutritional status of the host, inducing not only parasite-specific immunity but also can modify the host's immune responses . Many parasites can imitate inflammatory bowel disorders and some studies showed that infection with parasites can improve disorders like IBD or moderate the symptoms of inflammatory bowel disorders . Even though, many studies have shown that gastrointestinal infection is an important risk factor for the development of IBS
