Full description

Parasitic protozoal infections have prominent immunomodulatory changes in different autoimmune diseases. Moreover, helminths and their derivatives were established to have a protective role. Clinical trials of autoimmune diseases have tested the obvious helminths' immunomodulatory effect in inflammatory bowel disease, multiple sclerosis and rheumatoid arthritis . Autoimmunity is the immune system's inability to differentiate between foreign and self-antigens, resulting in damage of the healthy tissues . Recently, strong epidemiological studies revealed a steady increase in autoimmune diseases incidence in the developed countries. Also, The prevalence of the autoimmune diseases varies between rural and urban areas within the same country . The high records of autoimmune diseases incidences in these countries is attributed to the decline in infectious diseases prevalence "hygiene hypothesis ".

Multiple sclerosis (MS) is an inflammatory demyelinating disease affecting the CNS. Although its etiology remains obscure, several lines of evidence show that autoimmunity has a major role in the disease pathogenesis . Recent researches explain that parasitic infections can alter the disease course . Which is in the form of decreased number of relapses, minimal change in disability scores and lower MRI activity .

Childhood nephrotic syndrome (NS) is a worldwide disease with incidence and prognosis vary greatly according to the geographic distribution, with a prevalence of 15 per 100 000 under 16 years of age and higher incidence in South Asian (Pakistani, Indian, and Bangladeshi) and Arab children . NS is considered as a disease with immune impairment, Also some infections are found to be related to nephrotic syndrome . Parasitic infections may possibly be nonspecific triggers of NS . For instance, parasitic infections have been known to be associated with immune complex- mediated glomerular lesions . Moreover, parasites can mediate Altered T-helper cell cytokine expression, binding of autoantibodies to glomerular autoantigens, and immune complex formation .

The present study clarifies two very interesting and yet unexplored potentials, Do parasitic infections aggravate or ameliorate the course of autoimmune diseases? Also, what is the prevalence of parasitic infections in MS and NS in our governorate?
