Major depressive disorder in hepatitis C: an open-label trial of escitalopram.

BACKGROUND: Depression is a common condition associated with hepatitis C and may be induced by interferon alfa, the primary treatment for hepatitis C. Depression is also a major barrier to the initiation of such treatment. This study examined the effect of escitalopram on measures of depression, quality of life, and tests of liver function in subjects with comorbid hepatitis C and depression. METHOD: Subjects with DSM-IV major depressive disorder and hepatitis C were included in this open-label study. The recruitment period was from October 2002 through February 2004. Treatment status with regard to interferon therapy was neither an inclusion nor an exclusion criterion. Subjects received escitalopram for 8 weeks starting at 10 mg/day. Dosage adjustments up to 20 mg/day were made after week 4, as deemed clinically necessary. Scores on the 17-item Hamilton Rating Scale for Depression (HAM-D-17) and the Clinical Global Impressions-Severity of Illness scale (CGI-S) and results of liver function tests (AST, ALT, GGT) were obtained at baseline, 2 weeks, 4 weeks, and 8 weeks. Medical Outcomes Study Short Form Health Survey (SF-36) ratings and Hopkins Symptom Checklist-90-Revised (SCL-90-R) scores were obtained at baseline and week 8. RESULTS: Eighteen subjects (12 female, 6 male) participated in this study. The mean daily dose of escitalopram at endpoint was 12.78 mg. Mean HAM-D-17 scores decreased significantly with treatment (t = 8.535, df = 17, p < .0001). Statistically significant improvement was also demonstrated on many subscales of the SF-36, the SCL-90-R, and the CGI-S. Tests of liver function showed no significant changes. CONCLUSION: These results suggest that depression in patients with hepatitis C may be effectively and safely treated with escitalopram.

Delirium.

Delirium is characterized by an acute change in cognition and a disturbance of consciousness, usually resulting from an underlying medical condition or from medication or drug withdrawal. Delirium affects 10 to 30 percent of hospitalized patients with medical illness; more than 50 percent of persons in certain high-risk populations are affected. The associated morbidity and mortality make diagnosis of this condition extremely important. Patients with delirium can present with agitation, somnolence, withdrawal, and psychosis. This variation in presentation can lead to diagnostic confusion and, in some cases, incorrect attribution of symptoms to a primary psychiatric disorder. To make the distinction, it is important to obtain the history of the onset and course of the condition from family members or caregivers. Primary care physicians must be able to recognize delirium so that the underlying etiology can be ascertained and addressed. The management of delirium involves identifying and correcting the underlying problem, and symptomatically managing any behavioral or psychiatric symptoms. Low doses of antipsychotic drugs can help to control agitation. The use of benzodiazepines should be avoided except in cases of alcohol or sedative-hypnotic withdrawal. Environmental interventions, including frequent reorientation of patients by nursing staff and education of patients and families, should be employed in all cases.

An open-label trial of citalopram for major depression in patients with hepatitis C.

BACKGROUND: Hepatitis C affects nearly 4 million Americans. Depression is a common comorbid condition in this population and may be induced by interferon alfa, an approved treatment for hepatitis C. Depression is a major indicator for discontinuation of interferon therapy. This open-label study examines the effect of citalopram on measures of depression and quality of life and tests of liver function in subjects with hepatitis C and major depressive disorder. METHOD: Subjects were recruited by advertisement; those with DSM-IV major depressive disorder were included in the study. Subjects received citalopram for 8 weeks starting at 20 mg/day. Dosage adjustments were made as the physicians deemed clinically necessary. No dosages were increased prior to week 4 of the study. Hamilton Rating Scale for Depression (HAM-D) scores, Clinical Global Impressions-Severity of Illness scale (CGI-S) scores, Medical Outcomes Study Short Form Health Survey (SF-36) ratings, Symptom Checklist-90-Revised (SCL-90-R) scores, and liver function tests were obtained at baseline, 4 weeks, and 8 weeks. RESULTS: A total of 15 patients (10 men, 5 women) participated in this study. The mean daily dose of citalopram at endpoint was 26.67 mg. Mean HAM-D scores decreased significantly with treatment (F = 36.3, df = 2,42; p = .0001). Thirteen of the 15 subjects demonstrated a clinical response, defined as a 50% or greater reduction in HAM-D scores. CGI-Severity of Illness scores also improved significantly (p = .0001). Subjects demonstrated statistically significant improvement (p < .05) on all of the SF-36 subscales. Statistically significant improvements (p < .05) were also demonstrated on all subscales of the SCL-90-R. Tests of liver function showed no significant worsening of aspartate aminotransferase, alanine aminotransferase, or gamma-glutamyltransferase levels. CONCLUSION: These results suggest that depression in patients with hepatitis C may be effectively and safely treated with citalopram.

Plasma levels of citalopram in depressed patients with hepatitis C.

Hepatitis C affects an estimated 4 million Americans and 100 million people worldwide. Rates of depression are higher than that seen in the general population. Antidepressant therapy is often initiated at lower doses in patients with liver disease because of concerns about impaired metabolism and clearance. This study assessed plasma levels of citalopram in 15 subjects with hepatitis C and major depression during an 8-week trial. The mean citalopram dose at study completion was 26.67 mg/day. Mean plasma levels of citalopram, compared with levels previously reported, were lower than expected (at 10 mg/day [N = 1]: 21 ng/ml [N = 1]; at 20 mg/day [N = 8]: mean = 42.25 ng/ml, SD = 18.38; at 30 mg/day [N = 1]: 54 ng/ml; at 40 mg/day [N = 5]: mean = 76.2 ng/ml, SD = 35.86). There was a tendency for lower plasma levels to be found in those subjects receiving interferon, although a statistically significant difference was not observed. Citalopram was well tolerated. The results of this study suggest that patients with major depression and hepatitis C, but without evidence of severe liver disease, may be able to tolerate usual recommended doses of citalopram, thus avoiding the potential for undertreatment of the depression.
