Immuno-metabolic factors in schistosomal hepatic fibrosis modulating atherogenesis.

Clinical expression of atherosclerosis is infrequent among patients with schistosomal hepatic fibrosis (SHF), besides, the latter disease is a disease with many immunological expressions. The aim of the present work was to search for a possible immunological and metabolic interaction which would modulate atherogenic mechanisms. The study was carried out on 31 patients with SHF and 20 non-schistosomal subjects (10 with evident clinical atherosclerosis and 10 without). All investigated subjects were males aged above 40 years, and were subjected to the following: serum lipoprotein pattern, total cholesterol, phospholipids, triglycerides, ApoA, ApoB, IgG, IgM, IgA, C3 + circulating immune complexes (CICs) and passive haemagglutination using S mansoni adult worm antigens. The results showed low levels of blood lipids in patients with SHF especially in those with porto-systemic collaterals; serum levels of IgG and IgM were significantly increased in all patients with SHF, while IgA was only increased in patients with collaterals who in turn showed the least incidence of clinically evident atherosclerosis; serum C3 was increased in patients with clinical atherosclerosis, both schistosomal and non-schistosomal. CICs have been higher in patients with SHF without atherosclerosis while decreased in atherosclerosis patients, both schistosomal and non-schistosomal. Our results may consolidate the view of a protective role of liver affection against atherogenesis as well as the important contribution of the immune mechanisms in this context.

Study of eosinophilia in relation to serum IgE level and cell mediated immunity (CMI) to soluble egg antigen (SEA) in human schistosomiasis mansoni.

Eosinophil count, delayed intradermal test and lymphoblast transformation test (LTT) using SEA, have been used to study the correlation of eosinophilia with CMI in patients with schistosomiasis mansoni. Only a weak positive correlation was found between the eosinophil count and both in vivo and in vitro manifestations of CMI. When IgE serum level was correlated with eosinophil count, a positive correlation was only found in cases with hepato-splenic disease (those with increased CMI).

Thyroid function in hepatic schistosomiasis.

Serum thyroxine (T4), serum tri-iodothyronine (T3-uptake) and the free thyroxine index in 17 men suffering from hepatosplenic schistosomiasis did not differ significantly from those of ten healthy male controls. There was no correlation between these values and serum protein levels or liver function tests.
