Studies on certain serum enzymatic activities in hepatosplenic bilharziasis.

Determination of serum enzymatic activities in hepatosplenic bilharziasis (H.S.B.) were conducted in 100 bilharzial patients, in different stages and 30 controls SGot, SGPT, ALK pH, ALD and SLDH with its both fractions heat stable and labile.). Early elevation of serum enzymatic activities of SGOT, SGPT and SALK. pH, may be considered as a sensitive parameter for functional changes in H.S.B. rather than other conventional liver function tests. The elevated enzymic activity of total LDH in this study was associated with elevation in its both fractions. In particular, the changes in the total activity was in parallel with that of its heat labile fraction. The latter may be considered as a confirmatory test for marked deterioration of liver functions in H.S.B. The changes in the heat stable fraction was inconstant and may be attributed to extrahepatic bilharzial dissimilation. Significantly high serum enzymatic activity of SALD was found in cases of H.S.B. particularly those showing striking muscle wasting.

The coagulation profile in hepatosplenic schistosomiasis.

The biological activity of blood coagulation factors II, V, VII, VIII, IX, X, XI and XII, fibrinogen and prekallikrein was assessed in 15 healthy subjects and 60 patients with endemic Egyptian hepatosplenomegaly. The degree of liver disease was graded according to the Child-Pugh classification, the intensity of S. mansoni infection was monitored by determination of circulating schistosome immune complexes (CSIC) level using a monoclonal antibody and hemostasis activation was detected by measurement of hemostatic markers D-dimer and prothrombin fragment 1 + 2 (F1+2). Functional activity of antithrombin III, alpha2-antiplasmin and protein C as well as quantitative determination of plasma concentrations of alpha1-antitrypsin, C1 activator inhibitor and alpha2-macroglobulin were also carried out. The progressive deterioration of liver function which matched the severity of the disease and the intensity of schistosomal infection led to a reduction in anticoagulant proteins (decreases in antithrombin III and protein C) resulting in hypercoagulability and thrombin generation (increased F1+2) subsequently followed by consumption (prolongation of coagulation screening tests, thrombocytopenia, hypofibrinogenemia and decreased factor VIII resulting in hypocoagulability and secondary fibrinolysis (increased D-dimer and decreased alpha2-antiplasmin). A significant decline in fibrinogen and factors VII, XII and prekallikrein was detected in bleeders compared with ascitic patients. The decline in factor XII was closely related to CSIC high titers in all disease groups, but was not correlated to D-dimer or F1+2 concentrations. This suggests that circulating schistosome immune complexes may exert an inhibitory effect on contact factor XII which should be taken into account when considering the reasons for schistosomal coagulopathy and bleeding in hepatosplenic schistosomiasis.

[Liver involvement in HIV infection and various parasitic diseases].

During the course of systemic infections, the liver is an organ which is frequently involved. The pathology of the human immunodeficiency virus with all its infections, opportunistic tumours and some parasitoses, such as amebiasis, kala-azar, hydatidosis, schistosomiasis and fascioliasis, evolve into hepatic compromise. This development is what we attempt to summarise.

Some pathological and biochemical studies on experimental ascaridiasis in chickens.

During studying the pathogenicity of Ascaridia galli for young Ross-Broiler chickens fed with single doses of 100, 200 and 500 infective eggs, it was found that the infected chickens showed variable decreases in body weight gain and increases in the ratio of liver weight relative to body weight when compared with the control. Both decrease and increase was proportionally related with the number of infective eggs given to the chickens. Biochemical analysis of muscle and liver tissue of the previous groups of chickens showed a decrease in both glycogen and protein content and an increase in fat content of muscle and liver of infected chickens when compared with those of normal tissues. The decrease in the glycogen content due to ascaridiasis was mostly apparent in case of 500 egg dose and that of the protein content was noted with the egg doses of 200 and 500. Each of the three egg doses showed a significant increase in the fat content of the muscle and liver of infected chickens when compared with the control. After the sixth week of infection chickens fed with 500 eggs showed emaciation, loss of colour of combs and legs and of brightness of plumage, diarrhoea, drooping wings, ruffled feathers and a gradual loss of strength manifested by leg weakness. At autopsy, the small intestine showed external macroscopic lesions of haemorrhage and congestion. Intestinal obstruction with adult Ascaridia galli was also found in the infected birds.

Strobilocercus fasciolaris infection with hepatic sarcoma and gastroenteropathy in a Wistar colony.

Tapeworm cysts were identified in liver of Wistar rats and it induced fibrosarcoma in liver and gastroenteropathy in stomach and intestine. The tapeworm larva was confirmed as Strobilocercus fasciolaris by PCR linked mitochondrial DNA sequencing. Light microscopy, special staining (masson trichrome) and immunoflouresence supported the diagnosis of fibrosarcoma. Infiltration of plasma cells, macrophages and eosinophils were observed in the liver section. Gastric mucosal hyperplasia, dilation of gastric glands with secretion, intestinal mucosal cell hyperplasia, proliferation of duodenal submucosal glands were confirmed by light microscopy and supported by PAS, AB staining. The concomitant development of hepatic sarcoma and gastroenteropathy by larvae of Taenia taeniaeformis (S. fasciolaris) infection is very rare and is the first reported case in Wistar rats to our knowledge.

Opportunistic intestinal parasites among children with chronic liver disease.

Two hundred children were included in this study, 80 patients showing clinical and/or biochemical evidence of chronic liver disease, 80 immuno-compromised children due to causes other than chronic liver disease and 40 healthy control. All were subjected to detailed history, thorough clinical examination, investigated by liver function tests and stool examination by special techniques for opportunistic intestinal parasites. Autoimmune chronic hepatitis represented 12.5% of cases with chronic liver disease, hepatic schistosomiasis 30%, congenital cholestasis 25%, chronic viral hepatitis 20% and metabolic liver diseases 12.5%. The incidence of opportunistic intestinal parasites with chronic liver disease (92.5%) was nearly similar to the immuno-compromised ones (90%) and significantly higher than controls (30%). Mixed infection was not detected in controls while 57.5% of patients with chronic liver disease and 35% of immuno-compromised were infected by 2 parasites and 12.5% of each group was infected by more parasites. The commonest parasites were G. lamblia, E. histolytica and C. parvum but no Strongyloides stercoralis was detected. Children with chronic liver disease can be considered immuno-compromised and are liable to infection by opportunistic intestinal parasites.

Fibrosarcomas in two rats arising from hepatic cysts of Cysticercus fasciolaris.

Two of five male Sprague-Dawley rats with hepatic tapeworm cysts developed large multinodular fibrosarcomas. Fibrosarcomas envelope tapeworm cysts, invaded the serosa of multiple organs, and extended through the diaphragm into the pleural cavity. Light microscopy, immunohistochemistry, and electron microscopy supported the diagnosis of fibrosarcoma. The parasites were identified as Cysticercus fasciolaris, the larval stage of Taenia taeniaeformis. The development of sarcomas in rats induced by Taenia sp. is thought to be attributable to the chronic inflammatory reaction of the capsule. There are parallels between these and other tumors occurring in mice and cats with suggested chronic inflammatory etiologies.

Assessment of splenic functions in patients with hepato-splenic schistosomiasis using non-invasive techniques.

This study was carried out on forty cases, classified into 3 groups; group I: 10 healthy controls subjects, group II: 20 patients with hepatosplenic schistosomiasis and group III: 10 bilharzial patients who underwent total splenectomy. All cases were subjected to clinical examination, abdominal ultrasonography, rectal snips and laboratory investigations which included: stool and urine analysis, complete blood picture, IHAT for bilharziasis, liver function tests, viral markers, estimaton of T-lymphocyte subpopulations (CD(+)3, CD(+)4, & CD(+)8) by flow Cytometry, silver stained blood films to detect argyrophilic inclusions and 99mTc sulphur colloid splenic scan which was applied to group II only. The present results revealed varying degrees of hypersplenism (anaemia, leukopenia & thrombocytopenia) in GII. Seventy percent of this group was positive for HbsAg, HCV or both in association with schistosomiasis. Abnormal red blood cells (acanthocytes, target cells, pitted cells & normoblasts) and inclusion bodies (Howell Jolly bodies, argyrophilic inclusions & pappenhiemer bodies) were detected with different values in GIII. CD(+)4 cells were moderately reduced in GII while they were markedly decreased in GIII. CD(+)8 cells were elevated in GII and returned nearly to the normal values in GIII with decrease in number of total T-lymphocytes. Most patients of GII showed marked squestration of 99mTc labelled R.B.Cs. in the spleen with reversed hepatic/splenic ratio (normally hepatic/splenic ratio is over two). IHAT showed positivity in 90% of patients in GII while it was 50% in GIII. Although total splenectomy improved the haematological pattern and the cytopenias, which are prominent features in hepatosplenic schistosomiasis, yet the immunological profile was still altered. So, it is recommended to perform segmental splenectomy with retention of a normal mass of functioning residual spleen to preserve more immunological function and to protect against life-threatening occurrence of post-splenectomy sepsis.

[Hepatosplenic schistosomiasis: case report and clinical review].

Although seen rarely in Switzerland, schistosomiasis is a parasitosis affecting 200 to 250 million people round the world, mainly in tropical and subtropical regions of Africa, Asia, Central and South America. Depending on the parasitic species, the ureters and the bladder (S. haematobium) or the intestine and the liver (S. mansoni, S. japonicum, S. mekongi) are primarily involved. Other organs may be affected (lung, kidneys and central nervous system). Hepatosplenic schistosomiasis represents a special form of chronic infection by S. mansoni, S. japonicum or S. mekongi predominantly occurring in adolescents heavily and repeatedly infected during childhood, together with an additional genetic predisposition for the disease. Hepatosplenic schistosomiasis on a worldwide scale is one of the most prevalent causes of portal hypertension in man. We describe a 33-year-old Portuguese female with mansonian hepatosplenic schistosomiasis 12 years after leaving Africa, who had hepatosplenomegaly, portal hypertension, esophageal varices and hypersplenism. Splenomegaly and slight anemia had been known for years without prompting further work-up. Two months before diagnosis she had been delivered of a normal child after pregnancy without portal-hypertensive complications, namely esophageal hemorrhage. Because of placenta accreta, however, erythrocyte transfusion had been performed after delivery and was possibly responsible for hepatitis C found later on. Pathophysiology, clinical findings and therapy of the disease are discussed.

Clinical staging of malignant lymphoma in patients suspected to have hepato-splenic schistosomiasis.

Exploratory laparotomy, splenectomy and liver biopsy were carried out as a pre-treatment staging procedure in 32 cases of pathologically proved malignant lymphoma with clinically palpable spleen. The spleen was found to be negative for lymphoma in 17 cases, of which liver pathology showed bilharzial hepatic fibrosis in eight cases, nutritional cirrhosis in two cases and non-caseating granuloma in three cases. The liver was clinically positive in 13 cases. After laparotomy, three cases showed bilharzial pathology only. Bilharziasis has accounted for about one half of the false positive hepato-splenic involvement. These findings exemplify the usefulness of laparotomy as a staging procedure in regions endemic for hepato-splenomegaly.
