Pilot randomized controlled trial of Chinese herbal treatment for HIV-associated symptoms. Randomized, placebo-controlled trial of Chinese herb therapy for HIV-1-infected individuals. Preliminary report of a randomized, double-blind placebo-controlled trial of a Chinese herbal medicine preparation CH-100 in the treatment of chronic hepatitis C. Oral acyclovir prophylaxis against herpes simplex virus in non-Hodgkin lymphoma and acute lymphoblastic leukaemia patients receiving remission induction chemotherapy. A randomised double blind, placebo controlled trial.
We wished to determine the short-term safety and efficacy of a Chinese medicinal herb preparation in treating symptoms of human immunodeficiency virus (HIV) infection in a 12-week randomized, double-blind, placebo-controlled clinical trial in a University-affiliated acquired immunodeficiency syndrome (AIDS) clinic at a public general hospital. Thirty adults with symptomatic HIV infection, no previous AIDS-defining diagnosis, and CD4+ counts of 0.200-0.499 x 10(9)/L (200-499/mm3) received 28 tablets each day of either a standardized oral preparation of 31 Chinese herbs or a cellulose placebo. Primary outcome measures were changes in life satisfaction, perceived health, and number and severity of symptoms. Other outcomes included adherence, and changes in weight, CD4+ count, depression, anxiety, physical and social function, and mental health. Two placebo- and no herb-treated subjects had mild adverse events (AE). Subjects on both arms reported taking 94% of prescribed tablets. No differences between treatment groups reached the p < 0.05 level. Life satisfaction improved in herb-treated [+0.86, 95% confidence interval (CI): +0.29, +1.43] but not in placebo-treated subjects (+0.20, 95% CI -0.35, + 0.75). Number of symptoms was reduced in subjects receiving herbs (-2.2, 95% CI -4.1, -0.3) but not in those receiving placebo (-0.3, 95% CI -3.2, +2.7). There were trends toward greater improvements among herb-treated subjects on all symptom subscales except dermatologic. Believing that one was receiving herbs was strongly associated with reporting that the treatment had helped (p < 0.005), but not with changes in life satisfaction or symptoms. There were improvements in life satisfaction and symptoms among subjects receiving the herbal therapy. Whether Chinese herbs are effective in the management of symptomatic HIV infection can be adequately addressed only by larger trials of longer duration. Alternative medicine or complementary remedies that have not been scientifically tested are nonetheless widely used to treat chronic illnesses, particularly if curative options are limited.
                To assess the effectiveness of Chinese medicinal herbs in reducing symptoms and improving the quality of life of HIV-infected persons.
                Prospective, placebo-controlled double-blind study.
                University-based HIV outpatient clinic.
                68 HIV-infected adults with CD4 cell counts <0.5 x 10(9)/L.
                Participants were randomized to receive four daily doses of seven pills containing a standardized preparation of 35 Chinese herbs or placebo for 6 months.
                Symptoms, HIV disease progression, HIV-1 RNA plasma viral loads, CD4 and CD8 cell counts, and scores on standard questionnaires for quality of life, depression, anxiety, and coping.
                Intervention and placebo groups were equivalent at baseline regarding, respectively, previous antiretroviral therapy (74% versus 79%), median CD4 cell counts (0.20 x 10(9)/L versus 0.25 x 10(9)/L), and median HIV-1 plasma viral loads (35,612 copies/ml versus 52,027 copies/ml). At enrollment, none of the study subjects was seriously ill or depressed, and average coping and quality of life scores were in the normal range. In all, 53 (78%) participants completed the study. Patients taking Chinese herbs reported significantly more gastrointestinal disturbances (79% versus 38%; p = .003) than those receiving placebo. No therapy-related toxicities were observed. At completion of the study, no significant differences between the intervention and placebo groups were found regarding plasma viral loads, CD4 cell counts, symptoms, and psychometric parameters. HIV-1 RNA level was unchanged at study end. Among participants who were not on concomitant antiretroviral therapy, median CD4 cell counts declined by 0.05 x 10(9)/L in both the intervention and placebo groups.
                This standardized formulation of Chinese herbs for HIV-infected individuals did not improve quality of life, clinical manifestations, plasma virus loads, or CD4 cell counts. The data suggest that this formulation of Chinese herbs is not effective when administered in a Western medicine setting. The treatment of chronic hepatitis C is relatively unsatisfactory and many patients have turned to unproven alternative medicines to modify the course of their illness. We report a study of a Chinese herbal medicine preparation CH-100 in the management of chronic hepatitis C. Patients with documented chronic hepatitis C were randomly allocated to receive active herbal or placebo tablets (five tablets thrice daily). Patients were followed monthly and evaluated by a Western and a traditional Chinese medical practitioner. Therapy was monitored by measurement of liver function tests, creatinine and full blood count on a monthly basis. Twenty patients in each group were well matched for age, sex, duration of illness, previous interferon therapy and alcohol intake. Active Chinese herbal medication was associated with a significant reduction in alanine aminotransferase (ALT) levels over the 6 month study period (P < 0.03). No patient cleared the virus but four normalized their ALT on treatment. Appropriately prescribed Chinese herbal medicine may have a role in the management of chronic hepatitis C and further controlled studies are indicated. Forty-one patients receiving remission induction chemotherapy with vincristine, adriamycin and prednisolone (VAP) for high grade lymphoma or acute lymphoblastic leukaemia were entered into a double blind, placebo controlled trial of oral acyclovir prophylaxis against herpes simplex virus (HSV) infection. The dose of acyclovir was 200 mg four times daily for the duration of chemotherapy (six weeks). Of the 40 evaluable patients, 20 were randomised to each arm. Prophylactic oral acyclovir significantly reduced the incidence of clinical HSV infection from 60% on placebo to 5% acyclovir (P less than 0.001), and the incidence of viral isolates from 70% on placebo to 5% on acyclovir (P less than 0.001).
There is no firm evidence of efficacy of any medicinal herbs for HCV infection. Medicinal herbs for HCV infection should not be used outside randomised clinical trials.
