There are increasing challenges for the practising gastroenterologist in treating AIDS-related gastrointestinal diseases. The differential diagnoses of dysphagia and odynophagia include cytomegalovirus (CMV) and herpes simplex virus (HSV) infection, non-specific aphthous ulceration and non-AIDS oesophageal diseases, especially reflux oesophagitis. Chronic subacute abdominal pain with nausea, vomiting, early satiety and weight loss is suggestive of an obstructive lesion caused by lymphoma or Kaposi's sarcoma. Severe acute abdominal pain can indicate pancreatitis or intestinal perforation due to cytomegalovirus. Right upper quadrant pain (with or without fever, vomiting or abnormal liver function tests with a cholestatic profile) is suggestive of hepatobiliary pathology including cholecystitis, cholangitis, acalculous cholecystitis and AIDS cholangiopathy. Diarrhoea is the most common gastrointestinal symptom of AIDS, affecting 50-90% of patients. Causes of AIDS diarrhoea include protozoa (Cryptosporidium parvum, Isospora belli, Enterocytozoon bieneusi, Septata intestinalis, Cyclospora spp, Entamoeba histolytica and Giardia lamblia), bacteria (Mycobacterium avium-intracellulare, Clostridium difficile, Salmonella, Shigella and Campylobacter jejuni), and viruses (CMV, HSV and possibly HIV). Chronic diarrhoea, malnutrition and weight loss can shorten the life-span of patients with AIDS. Elemental diets, isotonic formulas, medium chain triglycerides and total parenteral nutrition have been tried with little success in AIDS patients with severe diarrhoea and wasting.

Cisplatinum is highly effective in numerous solid tumors and was evaluated in Hodgkin's disease clinical stages (CS) I/II. Sixty-five patients (43 male, 22 female; median age 25, with 12 patients under 16: CS IA-IIA 41, IB 5, IIB 19) were randomly assigned to one of the following arms (PAF87 protocol): 3 ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine with methylprednisolone) cycles (ABVD arm) or 3 ABVD plus cisplatinum cycles (ABVD-Plt arm) followed by radiotherapy (RT); extended field (40 Gy) RT with a short paraaortic field including the spleen (30 Gy) was then administered in the ABVD arm; extended field (30 Gy) without lombosplenic port prophylaxis. RT was administered in ABVD-Plt arm when patients were in complete remission (CR) after chemotherapy (CT). Median follow-up was 35 months (6-62 months). During CT, 1 patient (ABVD-Plt) died from viral meningo-encephalitis; five patients (1 ABVD, 4 ABVD-Plt) stopped treatment because of emesis, of whom three receiving only 1.5-2.5 (ABVD-Plt) cycles, are still in CR after 13-60 months. Fifty-five patients (27 ABVD-Plt) were in CR after CT. Among the 27 ABVD-Plt patients, all in CR after RT, two died (one from myocardial infarction and one from immunoblastic lymphoma); one patient from the ABVD arm died from gastro-intestinal hemorrhage in 1st CR. No ABVD-Plt patient relapsed; 1 ABVD patient relapsed in non-irradiated area. At five years, actuarial survival/relapse-free survival was 96.1/90% and 88.2/100% for ABVD and ABVD-Plt patients, respectively.

A nationwide multi-center cooperative phase II clinical study of irinotecan hydrochloride (CPT-11) was conducted to evaluate its efficacy in intractable malignant lymphoma and acute leukemia. In malignant lymphoma, one course of CPT-11 consisted of intravenous drip infusion at a dose of 40 mg/m2 once daily for 3 consecutive days, performed once a week. In acute leukemia, one course of CPT-11 consisted of intravenous drip infusion at a dose of 15 to 20 mg/m2 a day twice daily for 7 consecutive days (1 cycle), performed every 2 to 4 weeks. Among the 79 patients with malignant lymphoma and 50 patients with acute leukemia enrolled in the study, 66 and 41 patients, respectively, completed treatment. These patients had all undergone chemotherapy prior to treatment. Among the malignant lymphomas, the response rate in non-Hodgkin's lymphoma (NHL), including 9 CRs, was 42% (26/62, 95% CI: 30-54%); of these there was a response rate of 39% (5/13), including 1 CR, in adult T-cell leukemia (ATL) as well. In Hodgkin's disease (HD), on the other hand, there were no cases in which efficacy was demonstrated (0/4). The overall response rate in malignant lymphoma was 39% (26/66), and the response rate even among the recurrent intransigent cases was 42% (16/38). The 50% survival time (MST) in the 74 eligible cases of malignant lymphoma was 153 days. In acute leukemia, on the other hand, partial remission was observed in 2 of 17 cases (12%) of acute lymphocytic leukemia (ALL), but no cases of remission were observed in the 24 patients with acute myelogenous leukemia (AML). The overall remission rate in acute leukemia was 5% (2/41, 95% CI: 1-14%). The principal adverse effects were myelosuppression in malignant lymphoma and gastrointestinal symptoms, including diarrhea, nausea/vomiting, anorexia and abdominal pain, in both malignant lymphoma and acute leukemia, and there was little organ damage to the heart, liver or kidney. Myelosuppression and gastrointestinal adverse effects were severe in some of the patients, so caution is required. Based on the above findings, CPT-11 appears to be efficacious in the treatment of non-Hodgkin's lymphoma.

Twenty-four patients with a variety of malignant diseases (13 lymphoma, 4 myeloma, 1 ALL, 6 solid tumours) were treated with the alkylating agents busulphan and melphalan as a preparative regimen for autologous BMT. Thirteen males and 11 females, aged 27-53 years (median 39.5 years) received oral busulphan 1 mg/kg q6 h on days -6 to -3, followed by i.v. melphalan 140 mg/m2 on day -2 and infusion of cryopreserved haemopoietic cells on day 0. The major toxicity seen was gastrointestinal with nausea, vomiting and diarrhoea in 17 patients and severe mucositis in 22. There was no evidence of cardiotoxicity, nephrotoxicity, haemorrhagic cystitis or clinical signs of hepatic veno-occlusive disease. Twenty-three patients engrafted with the median duration of neutropenia (< 0.05 x 10(9)/l) 10 days (range 5-63 days) and thrombocytopenia (< 50 x 10(9)/l) 43 days (range 5-350 days). Three patients died of transplant-related complications. Of 15 evaluable patients with active disease at BMT, 9 responded and 6 were refractory. Sixteen evaluable patients were in CR after BMT. Seven relapsed, 1 died in remission and 8 remain in CR 12-46 months (median 29 months) later. Of the group of 13 lymphomas, overall and relapse-free actuarial survival at 36 months was 64% and 58%, respectively, while for the entire group of 24 patients these values were 39% and 34%. Busulphan and melphalan is a safe and inexpensive conditioning regimen for autologous BMT with acceptable toxicity and substantial antitumour activity particularly against lymphomas.

Primary lymphoma of the pancreas is an extremely rare condition. There are no previous reports from northern Europe. It is important to differentiate pancreatic carcinoma from lymphoma because there is significant difference between the prognosis and treatment. We describe here a case of primary pancreatic lymphoma in a 64-year-old woman who was admitted to hospital because of a sudden abdominal pain and vomiting. Ultrasound, computed tomography and endoscopic retrograde cholangiopancreatography findings are presented, and the features of pancreatic lymphoma in these imaging studies are discussed.

A 7-year-old boy presented with headache, vomiting, fever, epileptic seizure, and a left hemiparesis. Computed tomography revealed low-density areas in the left frontal lobe and right occipital lobe. Incisional biopsy of the right occipital lesion showed a diffuse and laminar destruction accompanied by microglial reaction in the cortex. An encephalitis of unknown etiology was suspected without data on viral titers in the serum and cerebrospinal fluid. Two months later right hemiparesis and ataxia appeared that were alleviated by prednisolone. Thereafter, similar symptoms repeatedly appeared, but disappeared after treatment with prednisolone. Approximately 5 years later, hemiparesis recurred: computed tomography revealed an 8 x 5 cm mass in the right lobe. A brain biopsy revealed non-Hodgkin's lymphoma of diffuse large, predominantly non-cleaved cell type of B-cell nature. The patient died 1 week after the surgery. The first biopsy specimen (taken at 7 years of age) did not contain Epstein-Barr virus genomes even when examined by polymerase chain reaction. The polymerase chain reaction and in situ hybridization techniques on the second biopsy specimens (taken at 12 years of age) revealed the Epstein-Barr virus sequences in the nuclei of diffuse large cell lymphoma. These findings suggested that the Epstein-Barr virus infection occurring between the first and second biopsies played an etiologic role in the pathogenesis of the brain lymphoma.

Although gout and hyperuricaemia are usually thought of as conditions of indulgent male middle age, in addition to the well-known uricosuria of the newborn, there is much of importance for the paediatric nephrologist in this field. Children and infants may present chronically with stones or acutely with renal failure from crystal nephropathy, as a result of inherited deficiencies of the purine salvage enzymes hypoxanthine-guanine phosphoribosyltransferase (HPRT) and adenine phosphoribosyltransferase (APRT) or of the catabolic enzyme xanthine dehydrogenase (XDH). Genetic purine overproduction in phosphoribosylpyrophosphate synthetase superactivity, or secondary to glycogen storage disease, can also present in infancy with renal complications. Children with APRT deficiency may be difficult to distinguish from those with HPRT deficiency because the insoluble product excreted, 2,8-dihydroxyadenine (2,8-DHA), is chemically very similar to uric acid. Moreover, because of the high uric acid clearance prior to puberty, hyperuricosuria rather than hyperuricaemia may provide the only clue to purine overproduction in childhood. Hyperuricaemic renal failure may be seen also in treated childhood leukaemia and lymphoma, and iatrogenic xanthine nephropathy is a potential complication of allopurinol therapy in these conditions. The latter is also an under-recognised complication of treatment in the Lesch-Nyhan syndrome or partial HPRT deficiency. The possibility of renal complications in these three situations is enhanced by infection, the use of uricosuric antibiotics and dehydration consequent upon fever, vomiting or diarrhoea. Disorders of urate transport in the renal tubule may also present in childhood. A kindred with X-linked hereditary nephrolithiasis, renal urate wasting and renal failure has been identified, but in general, the various rare types of net tubular wasting of urate into the urine are recessive and relatively benign, being found incidentally or presenting as colic from crystalluria. However, the opposite condition of a dominantly inherited increase in net urate reabsorption is far from benign, presenting as familial renal failure, with hyperuricaemia either preceding renal dysfunction or disproportionate to it. Paediatricians need to be aware of the lower plasma urate concentrations in children compared with adults when assessing plasma urate concentrations in childhood and infancy, so that early hyperuricosuria is not missed. This is of importance because most of the conditions mentioned above can be treated successfully using carefully controlled doses of allopurinol or means to render urate more soluble in the urine. Xanthine and 2,8-DHA are extremely insoluble at any pH. Whilst 2,8-DHA formation can also be controlled by allopurinol, alkali is contraindicated. A high fluid, low purine intake is the only possible therapy for XDH deficiency.

Idarubicin, a new analogue of daunorubicin, was administered intravenously at a dose of 15 mg/m2 to 31 patients with previously treated patients with unfavorable non-Hodgkin's lymphoma. Clinical characteristics included median age 69 years, performance status 1, and prior chemotherapeutic regimens 1. Twenty of the patients were relapsing after prior therapy and 11 were refractory; 29 had received prior anthracycline or anthracenedione. Responses were observed in 43% of patient (3 CR and 10 PR) with a median duration of 10+ months (2-29+ months). Idarubicin was well tolerated with non-hematologic toxicities (nausea/vomiting, mucositis, and anorexia) seen in < 50% of patients. Median hematologic values during the first cycle for this dosage included WBC 1300/mm3, platelets 129,000/mm3, and hemoglobin 10.9 mg/dl. With dose escalation, hematologic toxicity was dose-limiting. Symptomatic cardiac toxicity was observed in one patient who had received maximum dose doxorubicin and radiotherapy. Median values for the cardiac ejection fraction during the full course of therapy for the entire group of patients were 0.62 (initial) and 0.60 (final). Idarubicin in intravenous form is an active drug in previously treated patients with unfavorable non-Hodgkin's lymphoma. Further studies employing idarubicin in non-Hodgkin's lymphoma should be considered. Cardiac function should be followed in trials utilizing anthracycline-type chemotherapeutic agents.

A 79-year-old women with upper abdominal pain, vomiting and weight loss was found at endoscopy to have a large tumour mass in the gastric body. Histology of forceps biopsies revealed an adenocarcinoma of intestinal type. Gastrectomy was performed, but extensive lymph node metastasis precluded a curative surgical approach. Histopathological study of the specimen, however, revealed two distict malignancies, which arose in the setting of Helicobacter pylori-associated chronic gastritis with partial mucosal atrophy. One tumour was a gastric carcinoma, while the other was a primary B-cell lymphoma of the stomach (CD20-positive). The lymphoma comprised both a low-grade component (mucosa-associated lymphoid tissue- or MALT-type lymphoma), and a high-grade component (large cell lymphoma with CD30-positive giant cells). Infection with H. pylori was confirmed by the serological presence of IgG antibodies to H. pylori-antigens, including antibodies against the 128 kDa protein of the cytotoxin-associated gene (cagA gene) of H. pylori.

Six patients with either acceleration or blast crisis of transformed chronic myeloid leukemia (CML) were treated with high-dose interferon alpha in combination with hydroxyurea. All patients responded to the treatment by reversal to stable chronic phase. Two of these patients responded repeatedly during their course of disease. Median time for return to chronic phase was 4 weeks. Adverse side-effects such as nausea, vomiting, hairloss, fever, prolonged cytopenia were not observed.
