Malaria is a major public health problem. There were around 240 million cases of malaria and 627,000 deaths worldwide in 2020. Most of the deaths are in children under five living in Africa. It is a major problem for those who live in affected areas and for travellers. There is a great need for a safe, effective malaria vaccine. This study is being done to evaluate an experimental malaria vaccine for its safety and also look at the body's immune response to the vaccine. The vaccine tested in this study is called and "RH5.1". This is given with an adjuvant called "Matrix-M". This is a substance to improve the body's response to a vaccination. The aim is to use the vaccines and adjuvant to help the body make an immune response against parts of the malaria parasite. This study will assess: 1. The safety of the vaccines in healthy participants. 2. The response of the human immune system to the vaccines. This will be achieved by giving participants three doses of the RH5.1 vaccines at two different dose levels (10 micrograms and 50 micrograms). One group will have 3 doses of 10 micrograms given at 0, 1 and 6 months whilst the other will receive 2 doses of 50 micrograms (at 1 and 2 months) followed by a 10 microgram dose at 6 months- known as a 'delayed fractional dose'. Blood tests and information about any symptoms will be performed/collected that occur after vaccination. Information from previous studies suggests that a delayed fractional dose improves the immune response to the vaccine, particularly in terms of the antibody response. Current prediction is that this improvement is due to the delay in dosing, rather than the reduction in dose, and this study will help to answer that. Having a vaccine at a single dose is important for efficient production and dosing for vaccines rolled out in national programs so being able to move away from 'delayed fractional dose' regimens to 'delayed final dose' regimens will be important for vaccine development.
Pediculosis capitis or head lice infestation is a human medical condition caused by the infestation of the hair by the parasitic insect Pediculus humanus capitis (human head lice). The most common symptom of infestation is pruritus (itching) on the head which normally intensifies 3 to 4 weeks after the initial infestation. The test items have been developed with the ambition to offer a complete head lice treatment, whilst also offering ultimative convenience in use - making treatment of head lice infestation easy, and effective in few minutes. The main objective of this clinical study is to confirm the efficacy on head lice treatment of two Medical Devices, already in market.
The purpose of this study is to evaluate and compare the effect of two dosing regimens, BID versus TID dosing, of an Exploratory Vehicle (EV) on meibomian gland dysfunction (MGD) in patients with Demodex lid infestation.
This is an open-label, adaptive study using the P. falciparum induced blood stage malaria (IBSM) model to characterise the pharmacokinetic/pharmacodynamic (PK/PD) profile and safety of MMV367 (the IMP). Up to 18 participants will be enrolled in cohorts of up to 6 participants each. The study will proceed as follows for all participants: - Screening period of up to 28 days to recruit healthy adult participants. - Day 0: Intravenous inoculation with approximately 2,800 viable P. falciparum-infected red blood cells. - Days 1-3: Daily follow up via phone call or text message. - Days 4-7: Daily site visits for clinical evaluation and blood sampling to monitor malaria parasite numbers via quantitative polymerase chain reaction (qPCR). - Day 7 PM: Start of confinement within the clinical trial unit. - Day 8: Administration of a single oral dose of the IMP (MMV367). Different doses of MMV367 will be administered across and within cohorts in order to effectively characterise the PK/PD relationship. - Days 8-11: Regular clinical evaluation and blood sampling while confined to monitor malaria parasite numbers and measure MMV367 plasma concentration. - Day 11 AM: End of confinement within clinical trial unit. - Days 12-23: Outpatient follow-up for clinical evaluation and blood sampling. - Day 24: Initiation of compulsory definitive antimalarial treatment with Riamet® (artemether/lumefantrine) and/or other registered antimalarials if required. Treatment will be initiated earlier than Day 24 in the event of: - Insufficient parasite clearance following IMP dosing - Parasite regrowth following IMP dosing Characterising the pharmacokinetic/pharmacodynamic relationship of MMV367 - Participant discontinuation/withdrawal, - Investigator's discretion in the interest of participant safety. - Day 27: End of study visit for final clinical evaluation and to ensure complete clearance of malaria parasites.
Malaria is a major public health problem. There were around 240 million cases of malaria and 627,000 deaths worldwide in 2020. There is a great need for a safe, effective malaria vaccine and the team at University of Oxford is trying to make vaccine(s) which can prevent serious illness and death. This study is being done to assess an experimental malaria vaccine for its ability to prevent malaria illness. This is done using a 'blood-stage challenge model'. This is when volunteers are infected with malaria parasites using malaria-infected red blood cells. The vaccine we are testing in this part of the study is called "RH5.2-VLP". It is given with an adjuvant called "Matrix-M". This is a substance to improve the body's response to a vaccination. RH5.2-VLP is being tested for the first time in humans in this trial. The Matrix-M adjuvant has been given to tens of thousands of people, with no major concerns, such as illness. The aim is to use this vaccine and adjuvant to help the body make an immune response against parts of the malaria parasite. This study will assess: 1. The safety of the vaccine in healthy participants. 2. The response of the human immune system to the vaccine. 3. The ability of the vaccine to prevent malaria illness (Group 2 only). We will do this by giving healthy adult participants (aged 18-45) three of the vaccines and/or expose participants to malaria infection at the Centre for Clinical Vaccinology and Tropical Medicine (CCVTM), Churchill Hospital in Oxford. We will then do blood tests and collect information about any symptoms that occur after vaccination. There will be 19 to 54 visits, lasting between 3 months to 2 years and 2 months.
Chronic hepatic illness is one of the most serious health issues . Liver cirrhosis as the latest phase of chronic liver disease causes a disorder called cirrhosis-associated immune dysfunction syndrome (CAIDS) . Cirrhosis comes to be a systemic disease, with several organ disorders. At this phase, patients become highly vulnerable to various infections because of CAIDS, which comprises both innate and adaptive immunity). Patients with hepatic cirrhosis and ascites are more liable to other complications of liver disease, including hyponatremia, refractory ascites, or hepatorenal syndrome (HRS) . Liver cirrhotic patients are considered to be as immunosuppressed and are vulnerable to a different species of entero-parasites . Intestinal parasitic diseases have been reported in association with diabetes mellitus (DM) which is considered a predisposing factor to infection in cirrhotic patients . Immunosuppression among DM cases is due to increased blood glucose levels, which modifies several immune responses and this renders the body susceptible to various opportunistic infections comprising parasitic infections Intestinal parasites such as Blastocystis hominis, Cryptosporidium spp., Isospora belli, Cyclospora cayetanensis, and Microsporidia have appeared as significant opportunistic parasites that are responsible for severe illness in immunocompromised patients , subsequently, patients suffer from severe morbidity and high mortality).
Irritable bowel syndrome (IBS) is common medical disorder and represent a group of diseases of the gastrointestinal tract that is characterized by chronic abdominal pain , bloating , passage of mucus or straining with bowel movements, sense of incomplete evacuation after bowel movements or sense of urgency to move the bowels.Several parasites including Entamoeba. histolytica, Giardia spp., Blastocystis. hominis, and Trichinella spp. have been discussed as contributing factors to the development of IBS. B. hominis is one of the most common human intestinal protozoa in both developing and developed countries. some studies have reported a significant association between the parasitic infections, especially Blastocystis, and IBS.Cryptosporidium has been reported in IBS patients, with the onset of gastrointestinal symptoms after an acute episode of cryptosporidiosis despite recovery and parasite clearance.Numerous studies have been conducted to evaluate the association between the parasitic infections and IBS. Aim of the work: To detect prevalence of intestinal parasitic infections in irritable bowel syndrome patients in sohag.
