RESUMEN
BACKGROUND: Pharmacological treatment of depression in HIV-infected patients has been found to be effective. This study assessed the efficacy and feasibility of treatment with fluoxetine and the best method of administering the drug to patients with HIV infection. METHODS: Sixteen seropositive and 16 seronegative patients, equally matched for age and sex, who had Hamilton Rating Scale for Depression scores of at least 16 and who received at least 20 mg/d of fluoxetine for 8 weeks were studied. RESULTS: Depression was alleviated in both groups. However, improvement in the seropositive patients occurred later. INTERPRETATION: The results confirm the effectiveness of fluoxetine in treating depression in people with HIV infection. The lack of adverse effects makes this treatment particularly suitable, especially because seronegative people take longer to respond to treatment.

Though some epidemiological investigations support the association between pigment gallstone formation and chronic alcoholism with cirrhosis, little attention has been paid to the influence of alcohol itself on biliary bilirubin secretion, so that the pathogenesis of pigment cholelithiasis in alcoholics is hitherto unknown. On different days we intravenously administered ethanol (0.7 g/kg body weight), diluted with 500 ml of saline, or saline alone to 6 non-obese patients with an indwelling T tube and reestablished enterohepatic bile circulation. At the time of the investigation bile cultures were negative for aerobic and anaerobic bacteria. Ethanol significantly increased biliary unconjugated bilirubin in respect to control values. The phenomenon reached a maximum 2 h after alcohol infusion when the value of unconjugated bilirubin averaged 2.37 +/- 0.30% of total bilirubin in contrast to 0.65 +/- 0.14% in control conditions (p less than 0.01), and subsided 6 h after the end of ethanol infusion. Since increased amounts of biliary unconjugated bilirubin predispose to pigment stone formation, it can be speculated that alcohol contributes to pigment cholelithiasis pathogenesis by enhancing the biliary concentrations of this form of pigment.

Hydroxychloroquine and phlebotomy were compared in the treatment of porphyria cutanea tarda (PCT). Thirty patients received hydroxychloroquine (200 mg twice weekly) for 1 year and thirty-one underwent twice-monthly phlebotomies of 400 ml whole blood each, also for 1 year. Clinical signs of disease improved equally in both groups. At the end of the year, urinary porphyrin excretion had significantly improved in twenty-two out of thirty hydroxychloroquine-treated subjects, but in only eight out of the thirty-one patients who received phlebotomy. Liver histology showed significant regression of steatosis and siderosis in both groups compared with the pretrial biopsy, but the activity of liver disease, as judged by the extent of necrosis, inflammation and fibrosis, worsened in twelve hydroxychloroquine and in seven phlebotomy-treated patients. It is concluded that hydroxychloroquine is more effective than phlebotomy in decreasing porphyrin production. However, further work is needed to assess whether long-term hydroxychloroquine treatment favours the progression of the chronic liver disease associated with PCT.
