INTRODUCTION

Bone marrow transplantation is used to treat an increasing number of patients and diseases (1 2) As it is among the chiefly recent of advances in transplant medicine, the impact of lifetime substance abuse on recipients on bone marrow transplantation issue has yet to be systematically addressed.

In contrast, alcoholism and liver transplantation have been considered from the two medical and ethical aspects. Since alcoholic liver disease causes end-stage liver failure, be of importance tos about unsatisfactory rates of posttransplant survival if alcohol use is resum persist. lately however, Starzl, et al. have build that posttransplant results with alcoholic patients are comparable to those with other adult patients with other hepatic diseases (3456)

The project of this retrospective study is to criterion the hypothesis that lifetime substance abuse will have an adverse impact upon survival after bone marrow transplantation when other factors including disease and operation are equal. Substance abuse or reliance is defined according to the criteria established from the American Psychiatric Association in the Diagnostic and Statistical Manual of Mental Disorders, Third Edition--Revised (DSM-III-R, 7) and does not include individuals with insignificant or trivial use.

METHODS

Subjects

thought subjects were selected from 468 patients admitted since January 1990 to the Brigham and Women's Hospital in Boston for bone marrow transplantation. controls were eligible for inclusion if they were identified by the agency of nursing and physician staff to have a lifetime substance abuse question at admission.

reflection Design

Comparison patients were rareed from the BMT admissions roster without knowledge of the cogitation endpoint, survival time, by the first author. Criteria for matching included diagnosis and stage, pretransplant BMT conditioning regimen, BMT original (allogeneic, autologous, or matched unrelated), and age. Pretransplant conditioning regimen may consist of either chemotherapy or chemotherapy with radiation to ablate the patient's admit marrow. Matches were then reviewed and approved by means of the BMT Medical Director for medical comparability.

The medical records of patients with and without substance abuse puzzles were then reviewed and abstracted according to the first author, certified in Addiction Psychiatry, or the certified addictions counselor for confirmation of the patients' substance abuse status, course of transplant, result and demographic information. This close attention was approved by the Human Research Committee of the Brigham and Women's Hospital.

Data Analysis

Simple descriptive statistics comparing patients with and without substance abuse were calculated. eventuates are reported as percentages or as means with standard deviations.

Survival times were calculated from the date of admission to the date of last run after up. Failure was defined as death; patients still alive at last go in the rear [i]or[/i] in the wake of up were censored. Survival data were then analyzed using the SAS Lifetest process (8) to compute Kaplan Meier survival distributions and log rank touchstones for association of survival time with lifetime substance abuse. A secondary survival analysis was performed with stratification from history of cigarette smoking to proof for its potential association with survival time and to adjust for the result of cigarette smoking before assessing the drift of lifetime substance abuse forward survival. Finally, a third survival analysis was performed with stratification by way of type of bone marrow transplant to proof the association of survival time with symbol of bone marrow transplant, and to adjust for impressed sign of transplant before assessing the power of lifetime substance abuse upon survival. All reported probability values are two-sided.

RESULTS

Seventeen patients were identified at BMT nursing and physician staff to have either present or remote substance abuse at admission. The positive substance abuse assessment was confirmed in all 17 cases by means of the expert substance abuse reviewers. Medical record data included comprehensive physician and nursing preadmission, admission and hospital assessments which ask for history, commonness and quantity of alcohol and substance use, evaluations complet by means of psychiatrists and social workers, and documented reports of patient substance abuse given to staff according to patient's family members. Eleven of the 17 (65%) patients acknowledged using substances up to the day of admission, similar as drinking 6 to 12 beers daily, smoking marijuana daily, or "eating" 30 percocet daily. near patients reported having blackouts and arrests for driving while intoxicated prior to admission, and single in kind who drank up to a fifth of spirits daily, was detoxified just couple months prior to transplant admission. Duration of substance use ranged from regular use for a year, to 3habitual use for many years.

The diagnostic impression was based forward all available information on chart review, and the probable DSM-III-R diagnoses are as follows: alcohol abuse or stay current, n = 6; alcohol abuse or prop in remission, n = 6; cocaine abuse, in remission, n = 1; marijuana abuse, in every one's mouth n = 5; opiate abuse or reliance current, n = 2; opiate abuse or support in remission, n = 3; benzodiazepine abuse, passing from hand to hand n = 1; polysubstance abuse or confidence (alcohol, opiate, and benzodiazepine simultaneously), generally received n = 1. Of note, 14 of the 17 patients with lifetime substance abuse or reliance were also cigarette smokers, with an average of 193 [+ or -] 102 pack years. None of the 17 comparison patients was ground to have lifetime substance abuse or concatenation In contrast to the substance abusers, merely 3 of these patients were cigarette smoker with an average of 70 [+ or -] 36 pack years.
