The acute reaction in the course of a total body irradiation (TBI) appears in an organ-specific damage of the stem cells. Moreover, there are unspecified central-nervous stress reactions. Clinical reactions are obtained by the study and symptomatic therapy is proposed. 90 patients with different forms of leukaemia were observed. We documented the course in a specific "protocol system". Reactions like an increase of body temperature, changes of pulse and blood pressure were registered. The occurrence of gastro-intestinal reactions is a typical symptom of the acute radiation syndrome e.g. vomiting and diarrhoea are demonstrated in dependence of the applicated dose of irradiation. Further symptoms of TBI appeared in the later period. Mucositis, parotitis, a decreased function of the salivary glands and diarrhoea as well as vomiting are characterized by different intensity and temporary termination. A difference between allogeneic and autologous transplantation is caused by a medicamental additional treatment. During the late period these symptoms will disappear completely. Moreover, after TBI and BMT late effects are a cataract and some changes in the hormonal system demanding a specific correction or substitution respectively.

BMT results in multiple toxicities and organ dysfunction, which significantly influence the nutritional status of patients. The preparative regimen, which includes high-dose chemotherapy (with or without radiotherapy), causes nausea, vomiting, diarrhea, mucositis, anorexia, dysgeusia, and xerostomia. Conditioning may also contribute to infection and organ dysfunction. TPN is used as the principal method of nutritional support during the first month after transplantation. Oral feedings are primarily employed thereafter. A team approach is required to manage the nutritional aspects of care effectively in this complex patient population.

We investigated the antiemetic efficacy and safety of intravenous ondansetron infusion in the BMT setting. We conducted prospective randomized comparison trials between ondansetron at 2 dose levels and metoclopramide (MCP) plus droperidol for the prevention of chemotherapy-induced nausea and vomiting in 2 patient populations scheduled to undergo BMT. One patient population (n = 30) received CY alone, the other population (n = 30) received combination chemotherapy of Bu and CY. The CY alone group received ondansetron for 3 days, and the Bu/CY group received ondansetron for 7 days. The primary endpoints were emesis control and nausea. Secondary endpoints included acute (headache, diarrhea and sedation) and delayed (engraftment and regimen-related) side-effects. In both trials, ondansetron provided better emesis control than did MCP plus droperidol during CY administration (P = 0.009, 3-day trial; P = 0.0022, 7-day trial). There was a wide interpatient variation in serum ondansetron levels, although group averages were proportional to the dose administered. Intrapatient day-to-day variation was 10-30% and did not change significantly with concurrent CY administration. Antiemetic efficacy did not correlate with ondansetron serum levels at the doses tested. Headache incidence was similar in all groups. Sedation was highest in the MCP plus droperidol group (P = 0.048, 3-day trial; P = 0.016, 7-day trial). No statistically significant differences in engraftment or regimen-related toxicities were observed between groups in either trial. Ondansetron appears to be a safe and efficacious antiemetic during conditioning for BMT.

Intestinal biopsy samples derived from 22 consecutive patients with severe diarrhoea (> 1.5 1/day for 3 or more consecutive days) following allogeneic BMT were analysed for the local presence of cytomegalovirus (CMV) and histological and immunohistological alterations described as typical for acute graft-versus-host disease (GVHD). Seventeen patients showed extensive histopathological lesions typical for acute intestinal GVHD grade > I, 14 marked GVHD-related immunohistological alterations. In intestinal biopsies from 10 of these 22 patients CMV-DNA was detected using PCR- and in situ hybridisation techniques. In 7 of these 10 CMV-DNA positive samples CMV protein expression and in 5 cytomegalic cells were demonstrated. CMV could predominantly be shown in biopsies obtained from the ascending colon and/or the terminal ileum. All 10 patients with local CMV infection showed severe histopathological and immunohistological alterations described as typical for acute intestinal GVHD. Five of seven patients with a CMV-positive intestinal biopsy showed marked improvement of lower gastrointestinal tract disease on antiviral therapy. Five of seven patients lacking local presence of CMV but with severe histopathological lesions responded to therapy with high-dose steroids. Thus, PCR screening for CMV and histopathological analysis may help to treat lower intestinal disease in the marrow transplant recipient early and effectively.

An unrelated donor bone marrow transplant (UD-BMT) was carried out on a 10-year-old patient with metachromatic leukodystrophy (MLD). We collected cerebrospinal fluid (CSF) on day +168 and cultured it with recombinant IL-2 and PHA-P to examine the origin of cells in the CSF. Analysis on variable number of tandem repeat (VNTR) of lymphocytes in the CSF amplified by PCR revealed that lymphocytes in the CSF were of donor origin. These data support that BMT at an early stage may prevent deterioration in MLD. Although the patient developed grade III acute GVHD with rash and diarrhea, we successfully treated acute GVHD using rabbit anti-human thymocyte immunoglobulin (ATG). UD-BMT may be an alternative treatment for patients with MLD in the absence of an HLA matched family donor.

Two patients developed acute severe rotavirus-associated diarrhoea following BMT. Both received treatment with oral immunoglobulin and in each case the diarrhoea substantially resolved within 3 days, and rotavirus became undetectable in their stool. Oral immunoglobulin may be a useful therapy for rotavirus gastroenteritis post-BMT.

Diarrhea in marrow transplant recipients is a frequent complication attributable to non-infectious events such as acute GVHD or infectious events such as viral gastroenteritis. Rotavirus and enteric adenovirus are the most frequent viral pathogens. To determine the frequency of these infections, we prospectively examined the stool specimens of 94 patients who underwent autologous BMT (34 cases) or allogeneic BMT (60 cases). Stool specimens were examined from patients twice weekly. Nineteen of the 94 patients were infected with viral pathogens. This study showed: (1) an incidence of viral gastroenteritis identical in autologous and allogeneic BMT (20%), (2) a persistent risk despite treatment in laminar air flow rooms, (3) a significant association with severe acute GVHD, and (4) a significant risk of multiple viral infections in autologous BMT recipients. Rotavirus and adenovirus are a cause of enteritis involvement in patients undergoing BMT and they may be underdiagnosed and confused with GVHD. Screening of stool specimens after BMT should be directed to prevention and treatment of these viral infections to decrease the morbidity and mortality associated with BMT.

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.

We report the case of a 14-year-old boy with myelodysplastic syndrome (MDS/RAEB) which developed following Fanconi anemia. The patient received BMT from an HLA-identical sister. Based on the in vitro CY-sensitivity test, 100 mg/kg of CY was administered for conditioning combined with 6 Gy TBI. Mucosal symptoms such as stomatitis, diarrhea and hematuria were severe, but manageable, and engraftment was successful. The patient has maintained normal trilineage hematopoiesis with > 90% Karnofsky score for 30 months with disappearance of a clonal chromosomal abnormality (47,XY, +i(lq)) which was detected before BMT.
