Parasite Immunol 2018 Sep 21:e12591. Epub 2018 Sep 21.

Medical Research Council/Uganda Virus Research Institute and London School of Hygiene & Tropical Medicine Uganda Research Unit, Entebbe, Uganda.

While antigens from Schistosoma schistosomula have been suggested as potential vaccine candidates, the association between antibody responses to schistosomula antigens and infection intensity at reinfection is not well-known. Schistosoma mansoni infected individuals were recruited from a schistosomiasis endemic area in Uganda (n=372), treated with 40mg/kg praziquantel (PZQ) and followed up at five weeks and at one-year post-treatment. Pre-treatment and five-week post-treatment immunoglobulin (Ig) E, IgG1 and IgG4 levels against recombinant schistosomula antigens rSmKK7, rSmLy6A, rSmLy6B and rSmTSP7 were measured using ELISA.

Medical Research Council/Uganda Virus Research Institute and London School of Hygiene & Tropical Medicine Uganda Research Unit, Entebbe, Uganda.

Larvae of Schistosoma (schistosomula) are highly susceptible to host immune responses and are attractive prophylactic vaccine targets, although cellular immune responses against schistosomula antigens in endemic human populations are not well characterized. We collected blood and stool from 54 Schistosoma mansoni-infected Ugandans, isolated peripheral blood mononuclear cells and stimulated them for 24 hours with schistosome adult worm and soluble egg antigens (AWA and SEA), along with schistosomula recombinant proteins rSmKK7, Lymphocyte Antigen 6 isoforms (rSmLy6A and rSmLy6B), tetraspanin isoforms (rSmTSP6 and rSmTSP7). Cytokines, chemokines and growth factors were measured in the culture supernatants using a multiplex luminex assay, and infection intensity was determined before and at one year after praziquantel (PZQ) treatment using the Kato Katz method.

THE EFFECT OF STEM CELLS AS AN ADJUVANT ON THE IMMUNOGENICITY OF A POTENTIAL ANTI-SCHISTOSOMAL VACCINE IN MICE.

J Egypt Soc Parasitol 2016 Dec;46(3):693-716

Vaccination against schistosomes can be targeted towards the prevention of infection and/or to the reduction of parasite fecundity and pathology. However, as eggs are responsible mainly for schistosomiasis pathology, so crude soluble egg antigen (SEA) seems suitable to be used as a potential vaccine. Many studies have provided new insights establishing a role for mesenchymal stem cells (MSCs) in liver regeneration and improvement of schistosomiasis hepatic fibrosis, in addition to the need for standardized and effective adjuvant-vaccine formulations.

Parasitic infections of the gut have major implications for child health, but many questions remain unanswered. Protozoal parasites, especially cryptosporidiosis and giardiasis, cause diarrhoea and contribute to impaired growth, neurocognitive development and mortality. Entamoeba histolytica causes dysentery and may have more subtle effects on child growth. Read More

Egyptian Canopic Jars at the Crossroad of Medicine and Archaeology: Overview of 100 Years of Research and Future Scientific Expectations.

Pathobiology 2018 08 21:1-9. Epub 2018 Aug 21.

Ancient Egyptian human remains have been of interest in the fields of both medical and Egyptological research for decades. However, canopic jar holders for internal organs (liver, lungs, stomach, intestines) of Egyptian mummies appear to be but a very occasional source of data for such investigations. The few medical approaches focusing on the content of these jars are summarized and listed according to pathogens and diseases to give a structured overview of this field of study. Read More

Praziquantel-lipid nanocapsules: an oral nanotherapeutic with potential tegumental targeting.

Int J Nanomedicine 2018 6;13:4493-4505. Epub 2018 Aug 6.

Department of Pharmaceutics, Faculty of Pharmacy, Alexandria University, Alexandria, Egypt,

Purpose: Lipid nanocapsules (LNCs) have shown potential to increase the bioavailability and efficacy of orally administered drugs. However, their intestinal translocation to distal target sites and their implication in pharmacokinetic (PK)-pharmacodynamic (PD) relationships are yet to be elucidated. In this study, the effect of LNCs on the PD activity and pharmacokinetics of praziquantel (PZQ), the mainstay of schistosomiasis chemotherapy, was investigated. Read More

Liposomal Curcumin Attenuates the Incidence of Oxidative Stress, Inflammation, and DNA Damage Induced by Copper Sulfate in Rat Liver.

Dose Response 2018 Jul-Sep;16(3):1559325818790869. Epub 2018 Aug 9.

Pharmacology Department, Faculty of Pharmacy, King Saud University, Riyadh, Saudi Arabia.

Background: Copper is an essential element that is used widely in agriculture as fungicides and insecticides; for example, it is used to control schistosomiasis and as an antiseptic and germicide. Copper sulfate (CuSO) induces multiorgan dysfunction through the stimulation of reactive oxygen species and oxidative stress. Despite the numerous pharmacological effects of curcumin (CUR), its pharmacokinetic properties are less promising. Read More
