Addressing tri-morbidity (hepatitis C, psychiatric disorders, and substance use): the importance of routine mental health screening as a component of a comanagement model of care.
BACKGROUND: Recent studies suggest that most patients with hepatitis C virus (HCV) infection commonly present to medical clinics with active psychiatric and substance use disorders. However, routine screening for these disorders is generally not done. OBJECTIVES: The purpose of our study was to assess prospectively the frequency of psychiatric and substance use disorders in patients presenting for initial assessment of a positive HCV antibody test result. METHODS: A sample of 293 patients represented the majority of patients scheduled for their initial hepatology clinic visit at the Portland Veterans Affairs Medical Center between September 2002 and September 2003. The patient screening questionnaire, Alcohol Use Disorders Identification Test-Consumption (AUDIT-C), and the Beck Depression Inventory (BDI-II) were administered to all patients. RESULTS: At screening, 93% of the patients had a current or past history of at least 1 psychiatric disorder, and 73% had >or=2 disorders. The most common disorders included depression (81%), posttraumatic stress disorder (62%), any substance use disorder (58%), bipolar disorder (20%), and other psychotic disorders (17%). One hundred two patients (35%) had baseline BDI-II scores in the moderate-to-severe range of depression (>19), and 61 (21%) had AUDIT-C scores indicating current heavy alcohol use (>or=4). CONCLUSIONS: Psychiatric and substance use disorders are highly prevalent among veterans with chronic hepatitis C. Thirty-five percent have significant symptoms of depression before the initiation of treatment with interferon (IFN). Routine screening for underlying psychiatric and substance use disorders and early treatment intervention before initiating antiviral therapy is essential to prevent worsening of depression and to optimize the outcome of treatment with IFN. Comanagement treatment models involving mental health care may expand the pool of patients eligible to receive treatment with IFN, as well as enhance treatment outcomes.

Liver transplantation in patients with alcohol and other substance use disorders.
It is unfortunate that LT is not the ultimate sobering experience. LT patients can and do relapse; however, relapse to alcohol or substance use should no more be considered a failure of LT than the recurrence of HCV after LT. It is a phenomenon of their addiction. As a group, the survival and outcomes of patients undergoing LT for ALD are not significantly different from those undergoing LT for other causes. The fact that few patients return to heavy and deleterious alcohol or substance use attests to the success of programs in selecting patients capable of caring for themselves and their livers after LT. In the pre-LT phase, establishing the correct addiction diagnosis is essential so that those at highest risk can be carefully monitored. Although information is emerging about other risk factors for relapse, the authors caution against considering patients with these characteristics as being categorically unfit for LT. Each individual is unique, and such factors should guide clinical decision making rather than being absolute contraindications. After LT, clinical interviews, preferably by a trained psychiatric physician or clinician, are essential to monitoring alcohol and substance use, and surveillance early on is required. Much work needs to be done with respect to substance use and relapse after LT because few studies have explored these issues. In addition, the special treatment needs of those who relapse has not been addressed. Treatment research is underway but has relied on traditional strategies that are not always applicable to LT recipients. Further areas to improve clinical care include improving health behaviors, specifically, smoking cessation. The authors anticipate that, in the near future, the ongoing work in this area will provide information and guidance to physicians and clinicians caring for these unique patients.

Immunosuppressants.
Immunosuppressants are prescribed to prevent rejection of transplanted tissues and organs and are also used in the treatment of autoimmune disorders. Consultation-liaison psychiatrists increasingly encounter patients taking these agents as the number of transplant recipients increases and the indications for the use of immunosuppressants expands. These drugs have potentially deleterious physical, mental, and biochemical side effects. In addition, transplant recipients and patients with autoimmune disorders commonly have comorbid illnesses that require pharmacologic treatment. The management of these patients is challenging secondary to the severity of these illnesses, the number of medications prescribed, and the potential for adverse drug-drug interactions. Knowledge of the pharmacokinetic properties of these drugs and the potential for serious drug-drug interactions that cause alterations in serum levels of the immunosuppressant medications is essential. Increased serum levels may cause serious toxic effects and decreased serum levels may lead to rejection of the transplanted organ or worsening of the autoimmune disorder. Adverse events may also occur when serum levels of medications prescribed for comorbid illnesses are altered by administration of immunosuppressants. The pharmacokinetic drug-drug interaction profiles of the glucocorticoids, cyclosporine, tacrolimus, sirolimus, mycophenolate mofetil, azathioprine, and monoclonal antibodies are discussed in this review.
