The prediction of abstinence from ethanol may be crucial to the optimal selection of liver transplantation candidates with alcoholism. Of 84 consecutive end-stage alcoholic patients who underwent transplantation (1986-1994) at our institution, we analyzed 63 long-surviving recipients for pretransplantation variables to predict posttransplantation abstinence (follow-up: 49.3 +/- 21 mo). Thirty-three pretransplantation variables were reviewed from our transplantation data base and supplemented and confirmed with interviews with recipients. The psycho-social inclusion criteria included the following: patient recognition of alcoholism, a domicile, an occupation, and at least one close personal relationship. The incidence of abstinence from ethanol was (50/63) 79%. A logistic regression of the 33 variables in conjunction with our above inclusion criteria accurately predicted abstinence (90% accuracy, chi2 model, P < .00001) based on the absence of previous history of any illicit drug use (Drug Use: yes = 1/no = 0), the presence of an active, personal life insurance policy (Life Ins: yes = 1/no = 0), number of alcoholic sisters (ETOH-SIS), and the length of pretransplantation abstinence (PRE-TRANS-ABS, mos): Prob. of abstinence = 1/1 + e(-F), F = -0.33 +/- 0.89 (DRUG USE) -1.02 (LIFE INS) -1.68 (ETOH-SIS) +0.24 (PRE-TRANS-ABS). In contrast, receiver-operating characteristic curve analysis found that 7 and 9 months of pretransplantation abstinence were the best cut-off points in predicting subsequent abstinence, but poor utility was noted at these points with this specific value alone (sensitivity 61-84%, specificity 64-68%). A separate analysis of high-risk patients with poly-drug use (n = 15, alcohol recidivism 8/15, 53%) and the remaining low-risk group of purely alcohol dependent patients (n = 48, alcohol recidivism 5/48, 10%) found no combination of variables was predictive of abstinence in either group. The length of pretransplantation abstinence is a relatively poor predictor of posttransplantation abstinence. Variables of comorbid substance use, social function, and possibly family history are more predictive in conjunction with our standard criteria and might be useful as tools in evaluating liver transplantation candidates whose primary diagnosis is alcohol-induced cirrhosis.

This study examined data collected from a sample of female sex workers (FSWs) during the first two years of a brief risk-reduction intervention for vulnerable populations that focused on substance use and HIV risk-related behaviours (2007-2009) as part of a rapid assessment and response evaluation study. In 2007, in collaboration with a local non-governmental organisation (NGO), an initiative was begun to roll out targeted harm reduction strategies for drug-using street based FSWs in Durban, South Africa. Data were collected on demographic characteristics, substance use and HIV risk behaviours to tailor these harm reduction strategies with participants. Over the first two years of the intervention, data were collected from 646 FSWs: 428 who reported being at low risk for HIV and 218 who reported being at high risk for HIV (defined as engaging in unprotected sex with sexual partners in the past 90 days). FSWs who had previously been diagnosed with HIV or a sexually transmitted disease (STD) were significantly less likely to report engaging in unprotected sex. Those who used over-the-counter or prescription (OTC/PRE) drugs reported engaging in unprotected sex significantly more often than FSWs who did not use these substances, while those who used heroin were less likely to report unprotected sex. The findings are encouraging in that those who are aware of their HIV status are less likely to engage in risky sexual behaviour, and therefore HIV testing and counselling is recommended. It indicates the need to identify strategies to encourage the likelihood of all FSWs, particularly those who are HIV-positive, to use condoms. It also encourages further research to investigate specific substances as possible predictors of high risk behaviours in high-risk populations of sex workers.
