A prospective randomised study was carried out to compare the effect of mesna (2-mercaptoethane sulphonate sodium) with that of forced diuresis in preventing cyclophosphamide induced haemorrhagic cystitis in marrow transplant recipients. Sixty-one consecutive BMT recipients were randomised for treatment with forced diuresis or mesna. The incidence of macroscopic haematuria was significantly lower in the mesna treated group (chi 2 = 4.03, P less than 0.05). No specific side effects of mesna were detected. The lymphopenia induced by cyclophosphamide in the aplastic recipients was similar in the mesna and forced diuresis groups suggesting that mesna has no effect on the lymphocytotoxic activity of cyclophosphamide, although 6 out of 7 episodes of graft failure documented in the study occurred in mesna treated patients. As a result of this study our present policy is to use mesna in all BMT recipients but to continue careful documentation of the incidence of graft failure.

Sodium D-glucaro-delta-lactam (ND2001) inhibited spontaneous pulmonary metastases of the highly metastatic B16 melanoma variant with a maximal inhibition rate of 99.5%, and 6 of 7 animals remained metastasis-free. Likewise, ND2001 inhibited the spontaneous pulmonary metastases of both Lewis lung carcinoma (3LL) with a rate of 98.0% (3 of 5 animals remaining metastasis-free) and rat KDH-8 liver carcinoma with a rate of 82.5% (3 of 7 animals remaining metastasis-free), although it was unable to inhibit the metastases of mouse BMT-11 fibrosarcoma and rat SST-2 breast carcinoma. Pretreatment with ND2001 in vitro inhibited the pulmonary metastases of the B16 variant and 3LL cells, which indicates direct action upon the cancer cells. When the invasive activity of cancer cells was measured by the Boyden chamber method, the number of invading B16 variant or 3LL cells was reduced with maximal inhibition rates of 93.0% or 89.9%, respectively, but pretreatment with ND2001 failed to reduce the invasive activity of BMT-11 or SST-2 cells. ND2001 showed neither cytocidal nor antitumor activity. These results suggest that ND2001 inhibited pulmonary metastases at the invasive step into the basement membrane by directly changing some property of the tumor cells.

In a retrospective analysis, 79 allogeneic bone marrow recipients treated with AmBisome prophylactically or because of proven or suspected invasive fungal infection (IFI) were evaluated in 92 episodes. The median duration of treatment was 14 (range 1-112) days. The mean maximum dose given was 1.64 +/- 0.8 mg kg-1 day-1 and the mean total dose was 1.29 +/- 2.28 g. The overall incidence of reported adverse events was 194, of which none had a serious outcome. In six cases, the drug was withdrawn as a result of toxic or allergic reactions: dyspnoea and flush (3), urticaria (1), cholecystitis (1) and disorientation (one case, probably not related to AmBisome). No anaphylactoid reactions were seen. Laboratory findings, including low serum potassium (48% of the episodes), increased serum creatinine (38%) and increased serum sodium levels (7%), caused no major clinical problems. Thirteen cases of verified IFI were evaluated regarding the efficacy of AmBisome. Survival or cure of the mycotic infection occurred in 5/13 patients (38%). Two patients were treated with AmBisome (3.6 and 3.3 mg kg-1 day-1) because of verified IFI before BMT. One died of IFI. The other died of venoocclusive disease of the liver (VOD) without histological evidence of active IFI. We found a significant (P < 0.05) reduction in autopsy-proven IFI, 12/199 (6%) compared to the period when only conventional doses of amphotericin B were used, 26/227 (11%).

The knowledge of renal function in the course of BMT is poor. We prospectively investigated glomerular and tubular function in 42 children who underwent BMT because of malignancy. Seventeen children were transplanted autologously. Investigations were performed before and immediately after the conditioning regimen. Inulin and creatinine clearance, albuminuria, urine excretion of alpha 1-microglobulin, beta-N-acetylglucosaminidase, alanine-aminopeptidase, intestinal alkaline phosphatase, and Tamm-Horsfall-Protein as well as sodium- and phosphatreabsorption were measured. The patients were classified regarding use of total body irradiation (tTBI) in the conditioning regimen. BEFORE CR: Glomerular filtration rate (GFR) was not influenced by the underlying diagnosis or previous treatment. Mean GFR was elevated compared with the reference group. Microalbuminuria was elevated in 15% of patients, and mean levels were higher than in the reference group. Proximal tubular dysfunction was indicated by an elevated excretion of alpha 1-MG in 54%, of beta-NAG in 66%, of AAP in 40%, and of IAP in 47%. Fractional sodium excretion was abnormal in 21%, phosphate reabsorption in 5% and THP-excretion in 7% of the patients. AFTER CR: Creatinine clearance was not affected by CR. After CR alpha 1-MG, beta-NAG, FENa, AAP, and IAP were increased compared with values before CR. TP/Clcr was decreased. Excretion of THP was not altered by CR. In patients without fTBI there was a greater increase in alpha 1-MG excretion and decrease in phosphate reabsorption after CR compared with patients conditioned with fTBI. We conclude that significant proximal tubular dysfunction is present in about 50-60% of patients before and in nearly all alter CR. Distal tubular function was less severely affected. Severity of nephrotoxicity after CR did not correlate with pre-existing abnormalities.

We earlier reported a sizeable protection conferred by 'mitochondria rich' (MT) fraction of adult B. malayi and the present study was planned to locate the candidate protective molecule/s in the active fraction. The MT fraction was subjected to sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) and the antigen bands showing strong immune-reactivity with the resistant mastomys sera were assayed for their lymphoproliferative response using splenocytes of protected animals. Of the eight such protein bands, one sub fraction with a molecular weight of approximately 34 kDa (BMT-5) produced utmost cellular proliferation and was therefore exploited for vaccination study. BMT-5 emulsified in Freund's adjuvant produced discernible protection causing 69 and 67% reductions in microfilaraemia and adult worm burden respectively along with sterilization of 68% of the recovered female parasites. Significant levels of filaria-specific and non-specific lymphoproliferation along with enhanced release of Th1 cytokines (TNF-alpha, IFN-gamma and IL-2) by splenocytes were observed in the vaccinated mastomys in addition to elevated levels of antigen-specific IgG, IgG2a, IgG2b and IgA. The peritoneal macrophages of immunized animals also revealed enhanced nitric oxide production in the presence of BMT-5. The findings suggest that approximately 34 kDa (BMT-5) molecules present in the MT fraction of adult B. malayi provided sizeable protection against infective larval challenge by generating a Th1 biased milieu in the host.
