Hepatic and intestinal schistosomiasis after orthotopic liver transplant.

Schistosomiasis affects 200 to 250 million people worldwide. Hepatic schistosomiasis is a well-recognized cause of chronic liver disease and portal hypertension. There are no previous reports of schistosomiasis post liver transplantation. We report on 2 cases of schistosomiasis in liver transplant recipients--a case of gastric schistosomiasis and a case of hepatic schistosomiasis. A discussion of the pathology of schistosomal infection and a rationale for screening potential liver transplant recipients from endemic areas follows.

Toxocariasis simulating hepatic recurrence in a patient with Wilms' tumor.

We report the case of a 3-year-old girl with stage I Wilms' tumor of favorable histology. During the course of chemotherapy 5 months post-diagnosis, an abdominal ultrasonogram revealed hypoechoic areas consistent with hepatic tumor recurrence. A liver biopsy performed to rule out recurrence of the malignancy was suggestive of toxocariasis and the diagnosis was confirmed by serologic testing. Although the patient had few classic signs of visceral larva migrans, her eosinophilia and family social history should have suggested this possibility. This case demonstrates that hepatic toxocariasis should be considered in evaluating hepatic hypoechoic lesions in a child, even when features typical of the disease are absent.

Evaluation of colchicine with or without praziquantel therapy in the control of hepatic fibrosis in murine schistosomiasis.

Colchicine alone or following praziquantel was given to mice infected with Schistosoma mansoni either 6 or 10 weeks post infection. Praziquantel increased body weight gain, histologically reduced number, diameter and cellularity of granuloma and improved liver function parameters. Early praziquantel therapy decreased hepatic collagen content as detected by the colorimetric method and the serum procollagen propeptide (PIIIP), while later treatment at the 10th week of infection increased hepatic collagen content and serum PIIIP. Colchicine therapy significantly decreased body weight gain with significant weight loss after early treatment. Colchicine did not change the histologic picture of schistosomal liver fibrosis; it induced a detectable hepatocytic injury recorded ultrastructurally and histologically with excitation of the inflammatory reaction in the granuloma and in portal tracts after early treatment. Excess pigmentation in macrophages and Kupffer cells, binucleation and large sized hepatocytic nuclei were evident after colchicine therapy. Colchicine increased hepatic collagen content microgram/mg protein, raised globulin and total serum protein and normalized the raised serum PIIIP of infected mice, but had no effect on PIIIP of normal mice. Early cessation of schistosomal infection evidently minimized the adverse effects of colchicine.

Visceral leishmaniasis after orthotopic liver transplantation: impact of persistent splenomegaly.

Visceral leishmaniasis was observed in a 50-year-old female liver transplant recipient 1 year following transplantation. Signs of active infection were low-grade fever, pancytopenia, persistent splenomegaly, positive cultures for leishmania in liver and bone marrow biopsy specimens, and newly positive leishmania serology. Following sequential therapy with pentavalent antimony and amphotericin B, blood values improved massively, bone marrow cultures became negative, and leishmania serology decreased. Secondary prophylaxis with fluconazole was instituted and the patient remains without signs of active infection 1 year after successful therapy.

Fulminant hepatitis in Kala-azar.

One hundred and fifty cases of Kala-azar were studied for evidence of hepatic involvement. The hepatic function was mildly affected in 25 cases and 3 cases had fulminate hepatitis. Most of the cases were cured after anti-Kala-azar therapy except 2 cases, who died of hepatic failure. This study suggests that fulminant hepatitis may be the outcome of Kala-azar, itself.

Cholangiocarcinoma coincident with schistosomiasis japonica.

The relationship of parasitic liver disease to cholangiocarcinoma has long been debated, and it has been reported that cholangiocarcinoma is associated with opisthorchiasis viverrini. We report herein a rare case of cholangiocarcinoma associated with schistosomiasis japonica. A 76-year-old Japanese man with jaundice was diagnosed with cholangiocarcinoma. Radical resection was not done because of hepatic arterial and portal vein invasion. Biliary microwave tissue coagulation therapy was performed with placement of a metallic stent endoprosthesis. Twenty-two months after the treatment, however, the patient died from hematemesis. Autopsy findings revealed that there was no distant metastasis, even in the area of regional lymph node metastasis. The primary tumor in the hepatic hilar region had been replaced by necrotic debris resulting from the microwave therapy, and an expandable metallic stent was located in the center of the debris. Histological findings showed schistosome eggs, which were old and microcalcified, in veins in the colonic submucosa. Glisson's fibrosis around the cancer lesion suggested that schistosomiasis japonica and cholangiocarcinoma can occur together with severe chronic inflammation of the portal vein.

Schistosoma haematobium: the pathology of experimental infection.

The pathologic changes in experimental animals infected with Schistosoma haematobium are reviewed and compared to the pathology in infected humans. The clinically important lesions in persons infected with S. haematobium are generally confined to the urogenital system. In experimental animals, functionally important lesions of the urogenital system are the exception but do occur in a significant proportion of infected primates. The acute lesions of the urinary tract in primates are similar to those in infected persons. Chronic lesions characterized by the extensive submucosal accumulation of calcified eggs are common in infected humans but uncommon in S. haematobium-infected animals.

Liver disease in early life in Kenya.

A survey of significant pathological abnormalities of liver in the first two decades of life is presented; this is based on biopsy and autopsy specimens received in the histopathology service in Nairobi over five years. It includes conditions which one might expect in a diagnostic service in any country, some of which are attributable to known local conditions, and others which show distinctive features in their occurrence of frequency. There is an unexpected number of cases of chronic aggressive hepatitis and cirrhosis and the latter is notable for its frequency in the first decade of life. Hepatocellular carcinoma also occurs rather commonly, although most often in the second decade and as a complication of cirrhosis. There is a marked male preponderance in chronic aggressive hepatitis, cirrhosis, hepatocellular carcinoma and schistosomiasis. It is unlikely that this is due to selection of cases and the series shows no indication of tribal influence. The possible role of infections and toxins, particularly in the genesis of chronic aggressive hepatitis and cirrhosis, is discussed. In the search for clues to pathogenesis, detailed systematic investigation of children with liver disease is advocated, paying particular attention to cultural background, and exposure to infections and toxic agents.

Serum and urinary ribonuclease in children with schistosomal hepatic fibrosis.

Serum and urinary RNase activity was determined in 15 normal children and in 52 children in various clinical stages of schistosomal hepatic fibrosis. The activity of serum RNase was compared with that of serum GOT, GPT and AP. The activity of serum and urinary RNase in the different schistosomal groups was significantly higher than in healthy children. The elevated levels of serum and urinary RNase activity were possibly due to malnutrition with tissue catabolism, zinc-deficiency and liver cell injury. Treatment with Astiban and protein-rich diet resulted in a significant decrease in serum and urinary RNase activity and an in significant drop in serum GOT, GPT and AP. Serum and urinary RNase appear to be more sensitive indices for evaluating the early metabolic disturbances in schistosomal patients than GOT, GPT or AP. Our findings also showed that the severity of cases could be graded according to the level of urinary RNase.

The spectrum of liver disease in the United Arab Emirates.

Of 209 patients with liver disease attending the Al Qassimi Hospital, Sharjah, 172 were suffering from acute hepatitis. The proportion harbouring the hepatitis B surface antigen was unknown. Of the remainder, 10 were suffering from chronic active hepatitis, five from primary hepatoma and six from cirrhosis. Infection with hepatitis virus B was regarded as of aetiological significance in three cases of chronic active hepatitis, four of primary hepatoma and two of cirrhosis.

In vivo imaging of tissue eosinophilia and eosinopoietic responses to schistosome worms and eggs.

Using a sensitive transgenic reporter mouse system and in vivo biophotonic imaging techniques, we present a dynamic analysis of eosinophil responses to schistosome infection. Use of this methodology provided previously unattainable detail on the spatial and temporal distribution of tissue eosinophilia and eosinopoietic responses to schistosome worms and eggs. Dramatic hepatic and intestinal eosinophilia in response to the deposition of schistosome eggs, with accompanying eosinopoiesis in the bone marrow, was observed between weeks 8 and 10 p.i., with subsequent downregulation evident by week 11. Contrary to expectations, we also demonstrate that schistosome parasites themselves induce significant intestinal eosinophilia and eosinopoiesis in the bone marrow at very early stages during prepatent infection.

Determination of the period for establishment of a liver network echogenic pattern in Schistosoma japonicum infection.

Schistosomiasis is caused by infection with Schistosoma haematobium, S. mansoni, S. japonicum, or S. mekongi. S. japonicum infection results in liver cirrhosis at the final stage. A "network" (NW) echogenic pattern on hepatic ultrasonography appears to be specific to S. japonicum infection. The principal aim of the present study was to determine the exact year(s) or even month(s) required for the establishment of the liver NW echogenic pattern from the initial infection in young patients with schistosomiasis japonica since there are few data on this important point. We conducted yearly ultrasonographic, serologic, coprologic, and physical examinations of schistosomiasis patients in the Philippines from 1996 up to the present. During that period, the total number of patients examined was approximately 2,000, among whom we selected 2 patients for determination of the duration required for NW establishment, when they were 10 years old. Although the exact time of initial exposure to schistosomes cannot be determined, the duration for the establishment of NW was definitively confirmed in patient no. 1 to be between 19-24 months based on the results of serologic and coprologic examinations. For patient no. 2, the circumstantial evidence suggested that the establishment of a NW might require 5 to 6 years at maximum. To the best of our knowledge, this is the first evidence-based report on the determination of the period required for the establishment of a liver NW echogenic pattern in S. japonicum infection in the Philippines.
