RESUMO
Soluble adhesion molecules namely soluble intercellular adhesion molecule-1 (sICAM-1) and soluble E-selectin (sELAM-1) were assayed in hydatid patients with or without complications. It was found that sICAM-1 was significantly increased in patients with hydatid cysts as compared to the control group. In lymphoedemic filariasis cases both sICAM-1 and sELAM-1 showed highly significant increase more than the control group. However, non of both soluble adhesion molecules were significantly elevated in patients with ascariasis, hymenolepiasis, heterophyiasis and strongyloidiasis as compared to controls. The results indicated that SICAM-1 & S ELAM-1 are useful markers for hydatidosis and filariasis, but not for ascariasis, hymenolepiasis, heterophyiasis and strongyloidiasis

A total of 280 patients, 240 infertile and 40 pregnant were subjected to thorough history taking, general and local examination for exclusion of organic lesion, laboratory investigations to exclude parasitic, bacterial and fungal infections. Sterile vaginal swab from the posterior fornix was taken, and examined by wet smear preparation, Giemsa staining and cultivation on C.P.L.M. medium for trichomoniasis infection. The mean age of the infertile group was 25.75+/-3.92, and of the control group was 21.6+/-2.38 (in years). The mean duration of infertility was 2.81+/-1.51 (years). Out of 240 infertile women, 18.75% complained of discharge, 17.5% itching, 15.42% dysuria, 14.58% dyspareunia, and 10% had cervical lesion. Of the 40 controls, 5% complained of discharge, 2.5% complained of itching, dysuria, dyspareunia, but none had cervical lesion. Of the total cases (280), 36 (12.9%) had T. vaginalis. The clinical data observed were significantly higher among the infertile group than the control group. Cultures were positive in 14.58% of the infertile group and 2.5% in the control group. The difference between the 2 groups was statistically significant. No doubt, T. vaginalis plays an important role in female infertility.

Two groups of patients were studied. First one included 50 schistosomiasis mansoni patients, 30 with simple infection, 10 with splenomegaly and with ascites. Second group included 111 patients of whom 20 with pure S. mansoni, 27 with pure HCV infection, 54 with mixed infection of schistosomiasis and HCV and 10 with schistosomiasis, HCV and typhoid fever. Serum transaminases and anti-HCV antibodies performed, showed anti-HCV raised levels in 10% of simple schistosomiasis, 60% in splenomegalic patients, 80% in ascites patients, and 7.1% in controls. Liver function tests in first group were within normal range except in those with ascites. In second group, liver function tests was norma in pure schistosomiasis patients, in pure HCV patients serum bilirubin was normal in 22.2%, AST, ALT and alkaline phosphatase were higher. In mixed infection, serum bilirubin was normal in 18.5%, serum transaminases were higher and alkaline phosphatase was normal among 77.7%. Patients with typhoid fever, HCV and schistosomiasis (12.6%) showed significant increase of liver function as compared with each of pure HCV or HCV and schistosomasis. Results were discussed.

A total of 47 patients with toxoplasmosis (21 cases) with amoebic liver abscess (14 cases) and with giardiasis (12 cases) as well as 14 healthy control were subjected to thorough history taking, clinical examination, stool & urine analysis, complete blood picture, ESR, C-reactive protein, ASO, widal test, blood cultures, liver function tests, serum creatinine, hepatitis viral markers, rheumatoid factor, auto-antibodies, stool culture, rectal snip, chest X-ray, abdominal sonar, level of serum adhesion molecules (sICAM-1, sELAM-1), ELISA detection of Toxoplasma antibodies in serum, liver biopsy, detection and counting of Giardia cysts. In toxoplasmosis group, highly significant increase in serum levels of sICAM-1 (P<0.01) and significant increase in serum levels of sELAM-1 (P<0.05) in comparison to control. However, only sICAM-1 levels were significantly increased in IgM cases more than in IgG cases. In amoebic liver abscess group, both sICAM-1 and sELAM-1 significantly increased when compared with control. In giardiasis group, highly significant increase of serum levels of sELAM-1 was noticed than in control group (P<0.01), while sICAM-1 showed no significant difference (P>0.05). There was no correlation between sELAM-1 and number of cysts in the stool (intensity of infection). Soluble forms of adhesion molecules especially sICAM-1 have the potentiality as good markers of endothelial damage, severity of disease and to less extend load of infection.

Cercariae were obtained in a large number from the maintained life cycle of S. mansoni. They were attenuated at different doses (20 Kr, 50 Kr, 60 Kr, 70 Kr and 80 Kr) of gamma radiation. Laboratory bred Swiss Albino mice were classified into 7 groups. Five groups were immunized with +/-500 S. mansoni cercariae. Two groups were used as positive and negative controls. All animals were sacrificed after 8 weeks. Spleen cell proliferative responses to Phytohaemagglutinin (PHA) were assessed in all groups. IL-10 was measured by ELISA in serum and splenic cells secretion in-vitro. RNA extracted from freshly isolated liver cells was analyzed for detection of mRNA of IL-10 by reverse transcriptase polymerase chain reaction (RT-PCR). The results showed augmentation of proliferative cell from the spleen in all vaccinated groups except with 80 Kr, irradiated cercariae group. The highest percentage of lymphocytes transformation was recorded among the mice immunized with 60 Kr, irradiated cercariae. After challenge, splenic responses in all groups declined progressively to the control level. IL-10 secretion from spleen cells of all vaccinated groups increased after challenge with the least level in 60 Kr, immunized challenged group. IL-10 mRNA expression was higher among 60 Kr, immunized with irradiated cercariae mice group than 70 Kr, one, but with no expression among 80 Kr, cercariae immunized ones.

There was significant increase in coccidia positive cases among Hodgkin lymphoma receiving chemotherapy as compared to control group (p < 0.05). The increase was highly significant in the group of acute lymphocytic leukaemia receiving chemotherapy as compared to control group (P < 0.01). The total percent of cases with single type of coccidia were 12.2% compared to multiple coccidial infections (4.3%). The most commonly associated parasite was Cryptosporidium. The total cryptosporidial infections (single and mixed with other coccidia) were 12.1% of the total studied cases. In the immunocompromised the prevalence was 14.3%. In the immunocompetents with diarrhoea, was 8.3% and in control was 5.6%. Microsporidial infections (single and mixed with other coccidia), being the least detected among the four intestinal spores forming coccidia, were 2.4% in the immunocompromised groups. No Microsporidium was detected in the immunocompetent or adult control groups. The total cyclosporal infections (single and mixed with other coccidia) were 6.3% of the total studied cases. In the immunocompromised groups, the prevalence was (8.3%) where in immunocompetent group, was 2.8%. None was detected in the control subjects. Single cyclospora was 3.0% while mixed Cyclospora represented 3.3% of all studied cases. The Isospora infections (single and mixed) were 3.8% of total patients. The prevalence among immunocompromised group was 5.2% and in immunocompetent patients was 2.8%.
