Treatment of hepatitis C infection.

HCV infection is one of the leading causes of chronic liver disease worldwide,and it results in cirrhosis, liver failure, and HCC. As a result, hepatitis C cirrhosis has become the principal indication for liver transplantation. Ironically,HCV infection can be cured with available antiviral therapies, but only a minority of infected persons has ever been treated. The current standard of therapy isa combination of PEG-IFNalpha and ribavirin, which produces high rates of SVRs(absence of detectable HCV RNA at least 24 weeks after cessation of therapy):42% to 56% in genotype 1 and 75% to 84% in genotypes 2 and 3. Recent reports indicate that the less frequent genotypes 4, 5, and 6 also are responsive to combination therapy. Recommendations for treatment of conventional and special patient populations were reviewed in detail. Newer therapeutics that are entering clinical trials provide hope that SVRs may be possible in patients who are difficult to treat and in nonresponders to current therapy.

The implications of weight changes with antipsychotic treatment.

Patients receiving treatment with atypical antipsychotics commonly experience weight gain, which can cause considerable distress and can have deleterious effects on cardiovascular health. Because of the associated weight gain and potential direct effects on glucose metabolism, atypical antipsychotics have also been linked to the development of type II diabetes mellitus. Data on long-term treatment with these agents show that clozapine and olanzapine, followed by risperidone, were associated with the greatest degree of weight gain. A large body of data suggests that during long-term treatment, patients receiving the atypical antipsychotic quetiapine experience minimal weight gain. Data also suggest that quetiapine treatment does not increase the risk of developing type II diabetes. The use of atypical antipsychotics is increasing, as these agents are being prescribed for schizophrenia in lieu of conventional antipsychotics. Furthermore, these drugs have efficacy for treating other conditions such as bipolar disorder. Physicians prescribing atypical antipsychotics must be aware of the risk of weight gain and its associated comorbidities.

Choosing an atypical antipsychotic.

The atypical antipsychotics vary in terms of their pharmacological profiles, particularly in relation to their tolerability, effects on safety parameters and patient acceptability. Olanzapine, risperidone and ziprasidone are associated with extrapyramidal symptoms (EPS) in a dose-dependent manner, whereas quetiapine has been shown to produce a significantly lower incidence of substantial EPS effects than haloperidol, and less EPS requiring treatment than risperidone. Similarly, unlike risperidone and haloperidol, quetiapine treatment has been associated with a significant reduction in serum prolactin levels, and has normalized raised prolactin levels after discontinuation of previous treatment. Weight gain is also one of the major unwanted adverse effects of treatment with many antipsychotic drugs but, in contrast, quetiapine has demonstrated a neutral or 'normalizing' effect on body weight. In comparison with other antipsychotics, quetiapine has been shown to possess a favourable safety profile, with no requirement for routine blood, thyroid, or liver monitoring during treatment. Overall, quetiapine therapy has produced high levels of patient satisfaction and compliance and this, coupled with its efficacy in reducing psychoses of various origins, has made it an attractive treatment option in both patients at increased risk of EPS, and the general population.

A Treatment Algorithm for Attention Deficit Hyperactivity Disorder in Cocaine-Dependent Adults: A One-Year Private Practice Study with Long-Acting Stimulants, Fluoxetine, and Bupropion.

A subgroup of adults in private treatment for cocaine dependence in remission reported a therapeutic effect from cocaine during the initial phases of cocaine addiction and, also, met DSM-IV criteria for ADHD. We report evidence that study subjects probably medicated their ADHD symptoms with cocaine and describe a 1-year treatment algorithm featuring long-acting stimulants that was effective in the management of their ADHD and cocaine dependence. Nineteen stable patients in full remission from all substance dependence were entered into an open label, prospective, treatment trial for ADHD. The treatment schedule consisted of the progressive introduction-and discontinuation of ineffective medication-of each of several medications in the following order: fluoxetine, bupropion, pemoline, sustained-release methylphenidate, dextroamphetamine spansules, and methamphetamine gradumets. Treatment of ADHD was successful. Several treatment regimens, especially those including long-acting stimulants, alone or in combination with other agents, were highly effective. All but 1 of the 19 subjects had a fully effective response for at least 1 full year. Mean UTAH scale scores were 7.4 before any medications were administered and 1.6 at the end of the study. Treatment proved successful in suppressing ADHD symptoms, with minimal cocaine slips or side effects.
