Adherence with naltrexone prescription advice in hospital outpatient alcohol rehabilitation programme

Background: The anti-craving drug, naltrexone, is used as a pharmacotherapeutic adjunct in the treatment of alcohol dependence. In addictive disorders, compliance issues remain central. There are limited data on compliance with naltrexone treatment regimens within formalized rehabilitation programs and even less data that identifies factors that have an impact on this. Objective: To study patient adherence to naltrexone medication regimens and examine whether patients' reported pre-treatment alcohol use, dependence severity and measures of psychological health are predictive of medication compliance. Method: Fifty outpatients meeting DSM IV criteria for alcohol dependence enrolled in 12-week rehabilitation programme. This included cognitive behavioural therapy (CBT) and naltrexone, 50 mg orally daily. Measures included: pharmacy prescription pick-up including number of tablets dispensed, programme attendance and patient pre-treatment alcohol use variables. Measures of psychological health included somatic symptoms, anxiety, social dysfunction and depression as measured by the General Health Questionnaire (GHQ-28). Results: Classifying the sample into compliant (greater than or equal to 90% medication pick-up) and less compliant groups, 66% of subjects were naltrexone-compliant. Pre-treatment alcohol use variables were not predictive of compliance. Although social dysfunction and depression tended towards poorer prescription filling, measures of psychological distress (GHQ-28) did not identify factors predictive of medication non-compliance. One patient withdrew from treatment because of naltrexone-induced dysphoria. Conclusion: Patients with alcohol dependence demonstrated high levels of anti-craving medication compliance, good rehabilitation programme participation and favourable outcomes. Naltrexone was well tolerated. Medication compliance in this study group compared well with those of other hospital populations with chronic disorders. Factors predictive of anti-craving medication compliance in alcohol dependence require further study.

Combination therapy with tacrolimus and anti-thymocyte globulin for the treatment of steroid-resistant acute graft-versus-host disease developing during cyclosporine prophylaxis

We report our experience with the combination of anti-thymocyte globulin (ATGAM) and tacrolimus in the treatment of 20 patients with steroid refractory and dependent acute graft-versus-host disease (GVHD) transplanted between August 1996 and February 2000. All patients received cyclosporine-based GVHD prophylaxis. Thirteen patients developed a maximum of grade TV, five grade III and two grade II acute GVHD, with 15 patients being refractory to steroids and five dependent on steroids. Patients were treated with ATGAM (15 mg/kg for 5 d) and tacrolimus (0.025-0.1 mg/kg/d) in addition to continuation of their high-dose steroids and cessation of their cyclosporine. Within 28 d of treatment, we observed eight complete responses (CR), six partial responses (PR) and six with no response. Overall response (CR + PR) was predicted by GVHD severity. Infectious complications occurred in 80% of patients. The median survival was 86.5 d (range, 21-1081 d) with 35% of patients remaining alive, Survival following combination therapy was significantly more likely in men (P < 0.001), skin-only GVHD (P = 0.027), less severe GVHD (P = 0.048), and in responders to tacrolimus and ATGAM (P< 0.001). In conclusion, concurrent introduction of ATGAM and tacrolimus is a promising therapeutic combination for GVHD refractory to steroids and cyclosporine.

Lipid-lowering therapy following major cardiac events: progress and deficits

Objective: To assess hospital prescribing of lipid-lowering agents in a tertiary hospital, and examine continuation of, or changes to, such therapy in the 6-18 months following discharge. Design: Retrospective data extraction from the hospital records of patients admitted from October 1998 to April 1999. These patients and their general practitioners were then contacted to obtain information about ongoing management after discharge. Setting: Tertiary public hospital and community. Participants: 352 patients admitted to hospital with acute myocardial infarction or unstable angina, and their GPs. Main outcome measures: Percentage of eligible patients discharged on lipid-lowering therapy and percentage of patients continuing or starting such therapy 6-18 months after discharge. Results: 10% of inpatients with acute coronary syndromes did not have lipid-level estimations performed or arranged during admission. Documentation of lipid levels in discharge summaries was poor. Eighteen per cent of patients with a total serum cholesterol level greater than 5.5 mmol/L did not receive a discharge prescription for a cholesterol-lowering agent. Compliance with treatment on follow-up was 88% in the group discharged on treatment. However, at follow-up, 70% of patients discharged without therapy had not been commenced on lipid-lowering treatment by their GPs. Conclusions: Prescribing of lipid-lowering therapy for secondary prevention following acute coronary syndromes remains suboptimal. Commencing treatment in hospital is likely to result in continuing therapy in the community. Better communication of lipid-level results, treatment and treatment aims between hospitals and GPs might encourage optimal treatment practices.

A histone deacetylase inhibitor, azelaic bishydroxamic acid, shows cytotoxicity on Epstein-Barr virus-transformed B-cell lines - A potential therapy for posttransplant lymphoproliferative disease

Background. Posttransplant lymphoproliferative disease (PTLD), driven by the presence of Epstein-Barr virus (EBV), is becoming an increasingly important clinical problem after solid organ transplantation. The use of immunosuppressive therapy leads to the inhibition of the cytotoxic T cells that normally control the EBV latently infected B cells. The prognosis for many patients with PTLD is poor, and the optimal treatment strategy is not well defined. Method. This study investigates the use of a histone deacetylase inhibitor, azelaic bishydroxamic acid (ABRA), for its ability to effectively kill EBV-transformed lymphoblastoid cell lines. Results. In vitro treatment of lymphoblastoid cell lines with ABRA showed that they were effectively killed by low doses of the drug (ID50 2-5 mug/ml) within 48 hr. As well as being effective against polyclonal B-cell lines, ABHA was also shown to be toxic to seven of eight clonal Burkitt's lymphoma cell lines, indicating that the drug may also be useful in the treatment of late-occurring clonal PTLD. In addition, ABHA treatment did not induce EBV replication or affect EBV latent gene expression. Conclusion. These studies suggest that ABHA effectively kills both polyclonal and clonal B-cell lines and has potential in the treatment of PTLD.

Use of high and low velocity cervical manipulative therapy procedures by Australian manipulative physiotherapists

The use of cervical manipulation presents concerns because of a risk of devastating side effects of trauma to the vertebral artery. Little is known about the frequency of use of cervical manipulation versus passive mobilisation by physiotherapists. A recent national, multi-centre randomised clinical trial of the physiotherapy management of cervicogenic headache provided an opportunity to gain an insight into practices of a sample of manipulative physiotherapists across Australia. The treatment records for the 100 subjects who received only manipulative therapy, or manipulative therapy with exercise as per the trial protocol, were audited. The results revealed that cervical manipulation was used in 20.2% of the 1090 treatments provided to these subjects but cervical joint mobilisation only was used in the vast majority of treatments (77.6%). Nevertheless, 42% of subjects were treated with cervical manipulation at some time. In most instances, manipulation was accompanied by passive mobilisation in the same treatment session. Patients were manipulated on one to six occasions and this occurred predominantly in the latter half of the 12-treatment program. Cervical manipulation was used less frequently in the group who also received exercise. The data suggest that the physiotherapists participating in this study used cervical manipulation selectively and relatively conservatively considering the high use of cervical mobilisation techniques. This may reflect their due regard to safety in the treatment of the cervical region.
