The role of ursodeoxycholic acid (UDCA) in the prevention of hepatic complications after allogeneic stem cell transplantation was studied in a prospective randomized open-label multicenter trial. A total of 242 patients were allocated to receive (n ‫؍‬ 123) or not to receive (n ‫؍‬ 119) UDCA in the dose of 12 mg/kg/d orally from the day preceding the conditioning until day 90 after transplantation. In the UDCA-treated group a significantly smaller proportion of patients developed a serum bilirubin level exceeding 50 M (18 of 123 versus 31 of 119, P ‫؍‬ .04), and similarly a smaller proportion of patients exceeded the alanine aminotransferase level of 100 U/L. There was no difference in the incidence of veno-occlusive disease of the liver. Compared to the control group, in the UDCA-treated group there was a nonsignificant trend toward a lower overall incidence of acute graft-versushost disease (GVHD) and a significantly lower incidence of grade III to IV acute GVHD (5 of 123 versus 17 of 119, P ‫؍‬ .01), stage II to IV liver and intestinal GVHD, and stage III to IV skin GVHD. There was no difference in the incidence of chronic GVHD or in the relapse rate. Among the patients given UDCA, the survival at 1 year was significantly better, 71% versus 55% (P ‫؍‬ .02), and the nonrelapse mortality rate was lower, 19% versus 34% (P ‫؍‬ .01), than in the control group. There were significantly more deaths in GVHD in the control group. In conclusion, UDCA administration reduced hepatic problems and severe acute GVHD and improved survival. These results suggest a role for UDCA in the prevention of transplantrelated complications in allogeneic transplantation.

After myeloablative treatment and allogeneic stem cell transplantation (SCT), patients are kept in isolation rooms in the hospital to prevent neutropenic infections. During a 3-year period, patients were given the option of treatment at home after SCT. Daily visits by an experienced nurse and daily phone calls from a physician from the unit were included in the protocol. We compared 36 patients who wished to be treated at home with 18 patients who chose hospital care (control group 1). A matched control group of 36 patients treated in the hospital served as control group 2. All home care patients had hematologic malignancies and 19 were in first remission or first chronic phase. Of the donors, 25 were unrelated. The patients spent a median of 16 days at home (range, 0-26 days). Before discharge to the outpatient clinic after SCT, patients spent a median of 4 days (range, 0-39 days) in the hospital. In the multivariate analysis, the home care patients were discharged earlier (relative risk [RR] 0.33, P ‫؍‬ .03), had fewer days on total parenteral nutrition (RR 0.24, P < .01), less acute graft-versus-host disease (GVHD) grades II-IV (RR 0.25, P ‫؍‬ .01), lower transplantationrelated mortality rates (RR 0.22, P ‫؍‬ .04), and lower costs (RR 0.37, P < .05), compared with the controls treated in the hospital. The 2-year survival rates were 70% in the home care group versus 51% and 57% (not significant) in the 2 control groups, respectively (P < .03). To conclude, home care after SCT is a novel and safe approach. This study found it to be advantageous, compared with hospital care. (Blood. 2002;100: 4317-4324)

We evaluated the analgesic efficacy, safety and tolerability of a novel chemokine receptor 2 (CCR2) antagonist, AZD2423, in posttraumatic neuralgia. This was a double-blind, randomized, parallel-group, multicentre study. One hundred thirty-three patients with posttraumatic neuralgia were equally randomized to 28days' oral administration of 20mg AZD2423, 150mg AZD2423 or placebo. The primary efficacy variable was the change of average pain score from 5days at baseline to the last 5days of treatment, measured by a numerical rating scale (NRS, 0-10). The secondary efficacy measures included NRS worst pain score, patient global impression of change, pain interference on sleep and activity, and Neuropathic Pain Symptom Inventory (NPSI). The change of the NRS average pain score was not significantly different between treatment groups (AZD2423 20mg -1.54; AZD2423 150mg -1.53; placebo -1.44). There were trends towards larger reduction of NPSI total score and NPSI subscores for paroxysmal pain and paresthesia/dysesthesia by AZD2423 150mg compared to placebo. No other secondary efficacy variables differed between treatment groups. The frequency and type of adverse events for AZD2423 were similar to placebo. Increased plasma levels of chemokine ligand 2 and reduced mean levels of monocytes (-30% by AZD2423 150mg) suggested that the administrated doses of AZD2423 had interacted with the CCR2 target. The CCR2 antagonist AZD2423 demonstrated no efficacy on NRS average pain scores and most of the secondary pain variables. The NPSI data suggested possible effects on certain sensory components of pain. There were no major safety or tolerability concerns.
