The study was conducted on 75 multitransfused children aged between 2 and 13 years who attended the Department of Paediatrics, LNJPN Hospital, New Delhi from July 1990 to July 1991. These included 64 cases of thalassaemia major, 4 cases of haemophilia, 3 patients of acute lymphatic leukaemia and one each of acute myeloid leukaemia, aplastic anemia, chronic idiopathic thrombocytopenic purpura and acute haemorrhagic pancreatitis. HBsAg was tested in all, Anti-HBc was tested in 44 patients and Anti-HCV in 43 patients. Anti HDV was tested in HBsAg positive patients and IgM anti-HAV was tested in patients suffering from hepatitis. Liver function tests were evaluated in all patients. HBsAg was positive in 31% of patients; 40% of males and 15% of females were HBsAg positive, the difference being statistically significant. 84% of patients were Anti-HBc positive, 21% were anti HCV positive, 4% were Anti HDV positive. 15% of the patients had post transfusion hepatitis. Anti HCV was present in 57% of the hepatitis patients; none had anti-HAV IgM.

Oxidative stress appears to play a role in the pathogenesis of a number of gastrointestinal disease states, including pancreatitis; gastric and duodenal ulcer disease; IBD; gastric, esophageal, and colon cancers; and hepatic injury secondary to alcohol, metal storage disorders, hepatitis, and ischemia/reperfusion injury. The nutritional antioxidants are attractive potential therapeutic and chemopreventive agents because they are inexpensive and have a relatively low toxicity profile. A word of caution should be noted: Some antioxidants, such as vitamin C, can be prooxidant under certain conditions, and systemically altering the redox state may have untoward effects on the inflammatory response in certain disease states. Thus, at the current time, antioxidant therapy should be restricted to randomized, controlled clinical trials, in which treatment effects can be closely monitored, and therapeutic efficacy can be determined with scientific accuracy.

We have developed a single-catheter technique for percutaneous isolated liver chemoperfusion (PILP) with hepatic venous isolation and charcoal hemoperfusion (HVI-CHP) for the treatment of malignant liver tumors. We report here the surgical technique, pharmacokinetics, and effectiveness of PILP in multiple advanced liver tumors. Twenty-eight patients with hepatocellular carcinoma (HCC) and 18 with metastatic liver tumors underwent a total of 61 PILPs with HVI-CHP. HVI-CHP was accomplished mainly by the single-catheter technique using a novel four-lumen, two-balloon catheter; it was used to isolate and capture total hepatic venous outflow and, at the same time, to direct the filtered blood to the right atrium. Under HVI-CHP, either doxorubicin 960-150 mg/m2) or cisplatin (150-200 mg/m2) was infused via the hepatic artery. The PILP was completed successfully in all 61 trials. Two of forty-six patients died early; one of necrotizing pancreatitis and the other of hepatic arterial thrombosis. Both deaths were related directly to the hepatic arterial catheter. Excluding these two deaths, the treatments were well tolerated. The major side effects were mild to moderate chemical hepatitis and reversible myelosuppression. Of the 27 evaluable HCC patients, 17 (63%) had an objective tumor response (5 complete and 12 partial responses). In 15 patients with colorectal hepatic metastases (CHM), 7 had a sharp decrease in serum carcinoembryonic antigen (CEA) levels (to < 50% of their pretreatment levels) after treatment. However, a single PILP had limited efficacy in terms of the durability of remission (< or = 6 months in most CHM patients, as assessed by CEA levels). These results indicate that PILP with HVI-CHP has high efficacy in most patients with multiple advanced liver tumors. In addition, the results suggest a role of multiple treatment courses of PILP in the induction of long-term remission, especially for patients responsive to the first treatment.

The investigation is concerned with developing a model for using blood serum from patients with hepatic tumors to induce the activity of a gamma-glutamyl transferase enzyme in homogenized bovine hepatic tissue culture. An immunoglobulin protein was found to be responsible for the effect. The technique under discussion (Patent No. 2027997) provides a means for differential diagnosis of hepatoma and liver metastasis, on the one hand, and cholecystitis, pancreatitis, hepatitis, echinococcosis and hemangioma of the liver, on the other. The effectiveness of the method was 94.7; sensitivity--90.8 and specificity--97.9%.

A 34-yr-old woman developed simultaneous pancreatitis and hepatitis following exposure to trimethoprim-sulfamethoxazole (TMP/SMX). The episode occurred 4 yr after a previous episode of hepatitis associated with TMP/SMX. This patient represents the second case of concurrent TMP/SMX-induced pancreatitis and hepatitis reported in the literature. However, it is the first in which the adverse reaction was documented following an inadvertent rechallenge with the drug.

Association of hepatitis viruses with acute pancreatitis in the setting of nonfulminant viral hepatitis is rare. We report six cases of nonfulminant viral hepatitis complicated by acute pancreatitis, including the first documented case of hepatitis E virus (HEV) associated acute pancreatitis. The other five patients had acute viral hepatitis caused by hepatitis A infection. Besides features of viral hepatitis, the presence of typical abdominal pain, high serum amylase, and ultrasound or CT scan features suggested the diagnosis of acute pancreatitis. This complication generally developed in the initial phase of the hepatitic illness. All of the patients had mild to moderate pancreatitis that recovered uneventfully with conservative treatment.

Cutaneous infection with Leishmania braziliensis complex requires treatment with parenteral pentavalent antimonials to prevent development of mucocutaneous leishmaniasis. Patients with imported disease are usually managed in hospital because of concerns over drug toxicity. This study describes the clinical features and outcome of infection treated in the UK in an out-patient setting. Thirteen marines (aged 19-35 years) who acquired leishmaniasis in Belize were studied prospectively. Three had at least two lesions (0. 6-3 cm diameter), eight had regional lymphadenopathy and one had localized painless lymphatic thickening. Histology for amastigotes and PCR for Leishmania braziliensis complex was positive in all. Culture was positive in six. Patients received 1.5-2 g (mean 1.7 g) (20 mg/kg) sodium stibogluconate intravenously daily for 20 days. All developed transient musculoskeletal symptoms and asymptomatic hepatitis. Eleven developed biochemical pancreatitis, and one thrombocytopenia. Three developed transient ECG changes and one herpes zoster. There were four device-related infections, two requiring hospitalization (one required surgical drainage of an abscess). All lesions re-epithelialized. A total of 250 bed-days were saved over a 67-day period. These results indicate that in selected patients, out-patient therapy for cutaneous leishmaniasis with parenteral high-dose sodium stibogluconate may be appropriate, provided there is adequate monitoring of therapy.

Porcine circoviruses (PCV) are small nonenveloped DNA viruses containing a unique single-stranded circular genome. Previously, no recognized link was found between PCV infection of pigs and disease, and PCV was considered a nonpathogenic agent. Over the last 5 years, a "novel" PCV, designated PCV2, has been associated with various disease syndromes in pigs, primarily postweaning multisystemic wasting syndrome (PMWS). Pigs with PMWS have a variety of clinical signs, including debility, dyspnea, palpable lymphadenopathy, diarrhea, and pallor or icterus. Lesions associated with the presence of PCV2 in a variety of cell types include lymphohistiocytic to granulomatous interstitial pneumonia, hepatitis, nephritis, myocarditis, enteritis, and pancreatitis. The lesions of PMWS have been reproduced experimentally after inoculation of piglets with PCV2 cell culture isolates, although the full expression of the disease syndrome may require the presence of other agents such as porcine parvovirus or porcine reproductive and respiratory syndrome (PRRS) virus. Recent reports have linked PCV2 to other disorders in pigs, ranging from abortion and reproductive failure to "atypical" PRRS. Available data indicate high seroprevalence of antibodies to PCV2 worldwide. The diagnosis of PCV2-associated disease is based on the direct demonstration of PCV2 antigens or nucleic acid in affected tissues. PCV2 is now regarded as an important emerging pathogen. Although vertical transmission has been documented, the epidemiology of PCV2 infections is poorly understood, as is the role of the immune response in controlling or augmenting disease.

Programmed cell death (apoptosis), a form of cell death, described by Kerr and Wyllie some 20 years ago, has generated considerable interest in recent years. The mechanisms by which this mode of cell death (seen both in animal and plant cells), takes place have been examined in detail. Extracellular signals and intracellular events have been elaborated. Of interest to the clinician, is the concentrated effort to study pharmacological modulation of programmed cell death. The attempt to influence the natural phenomenon of programmed cell death stems from the fact that it is reduced (like in cancer) or increased (like in neurodegenerative diseases) in several clinical situations. Thus, chemicals that can modify programmed cell death are likely to be potentially useful drugs. From foxglove, which gave digitalis to the Pacific Yew from which came taxol, plants have been a source of research material for useful drugs. Recently, a variety of plant extracts have been investigated for their ability to influence the apoptotic process. This article discusses some of the interesting data. The ability of plants to influence programmed cell death in cancerous cells in an attempt to arrest their proliferation has been the topic of much research. Various cell-lines like HL60, human hepatocellular carcinoma cell line (KIM-1), a cholangiocarcinoma cell-line (KMC-1), B-cell hybridomas, U937 a monocytic cell-line, HeLa cells, human lymphoid leukemia (MOLT-4B) cells and K562 cells have been studied. The agents found to induce programmed cell death (measured either morphologically or flow cytometrically) included extracts of plants like mistletoe and Semicarpus anacardium. Isolated compounds like bryonolic acid (from Trichosanthes kirilowii var. Japonica, crocin (from saffron) and allicin (from Allium sativum) have also been found to induce programmed cell death and therefore arrest proliferation. Even Chinese herbal medicine "Sho-saiko-to" induces programmed cell death in selected cancerous cell lines. Of considerable interest is the finding that Panax ginseng prevents irradiation-induced programmed cell death in hair follicles, suggesting important therapeutic implications. Nutraceuticals (dietary plants) like soya bean, garlic, ginger, green tea, etc. which have been suggested, in epidemiological studies, to reduce the incidence of cancer may do so by inducing programmed cell death. Soy bean extracts have been shown to prevent development of diseases like polycystic kidneys, while Artemisia asiatica attenuates cerulein-induced pancreatitis in rats. Interestingly enough, a number of food items as well as herbal medicines have been reported to produce toxic effects by inducing programmed cell death. For example, programmed cell death in isolated rat hepatocytes has been implicated in the hepatitis induced by a herbal medicine containing diterpinoids from germander. Other studies suggest that rapid progression of the betel- and tobacco-related oral squamous cell carcinomas may be associated with a simultaneous involvement of p53 and c-myc leading to inhibition of programmed cell death. Several mechanisms have been identified to underlie the modulation of programmed cell death by plants including endonuclease activation, induction of p53, activation of caspase 3 protease via a Bcl-2-insensitive pathway, potentiate free-radical formation and accumulation of sphinganine. Programmed cell death is a highly conserved mechanism of self-defense, also found to occur in plants. Hence, it is natural to assume that chemicals must exist in them to regulate programmed cell death in them. Thus, plants are likely to prove to be important sources of agents that will modulate programmed cell death.

Infections are thought to be important in the pathogenesis of many heart diseases. Coxsackievirus B3 (CVB3) has been linked to chronic dilated cardiomyopathy, a common cause of progressive heart disease, heart failure and sudden death. We show here that the sarcoma (Src) family kinase Lck (p56lck) is required for efficient CVB3 replication in T-cell lines and for viral replication and persistence in vivo. Whereas infection of wild-type mice with human pathogenic CVB3 caused acute and very severe myocarditis, meningitis, hepatitis, pancreatitis and dilated cardiomyopathy, mice lacking the p56lck gene were completely protected from CVB3-induced acute pathogenicity and chronic heart disease. These data identify a previously unknown function of Src family kinases and indicate that p56lck is the essential host factor that controls the replication and pathogenicity of CVB3.
