The Use of Complementary and Alternative Medicine for Liver Disease

Outcomes and Toxicology of Herbal Drugs in Alcoholic Hepatitis - A Single Center Experience from India

Background and Aims: We aimed to study clinical outcomes and liver biopsy features of alcoholic hepatitis (AH) patients on complementary and alternative medicines (CAMs) and to analyze the retrieved drugs for chemical and toxic components linked to drug-induced liver injury. Methods: We retrospectively assessed clinical, biochemical and liver biopsy features of AH patients on CAM with drug-induced liver injury (AH-CAM, n = 27) and compared them to a control group (classical AH, n = 29) on standard of care. Patients without liver biopsy evaluation and other causes for liver disease were excluded. Samples of the CAMs (n = 42) from patients were retrieved and assessed for chemical and toxins. Results: All were males, and significantly worse clinical presentation, biochemical severity, and liver disease scores were notable in patients with AH-CAM. Traditional Ayurvedic-polyherbal formulations were the most commonly used CAM. On liver histology, varying grades of severe-necrosis, severe hepatocellular, canalicular, cholangiolar cholestasis with predominant lymphocytic-portal-inflammation and varying grades of interface-hepatitis were noted in AH-CAM. Analysis of CAMs revealed presence of heavy metals up to 100,000 times above detectable range and adulterants, such as antibiotics, chemotherapy agents, nonsteroidal anti-inflammatory drugs, alcohols, antidepressants, anxiolytics, and recreational drugs. On follow up, a significantly higher number of patients with AH on CAM died at end of 1, 3- and-6-months compared to controls (37% vs. 83%, 29% vs. 62%, 18% vs. 52% respectively; p < 0.001). Conclusions: Patients with AH and CAM-related drug-induced liver injury have extremely poor short-term survival in the absence of liver transplantation compared to those patients with AH on evidence-based management. Early transplant referral and educating on and curbing of CAM use in severe liver disease through strict monitoring of unregulated traditional health practices can help ease the burden of liver-related death.

Meta-Analysis of Combination Therapy of Chinese Herbs Plus Interferon and Ribavirin in Patients with Chronic Hepatitis C

BACKGROUND We aimed to evaluate the combination therapy of Chinese herbs plus interferon and ribavirin in treatment of patients with chronic hepatitis C (CHC). MATERIAL AND METHODS Related databases were searched to identify randomized controlled trials (RCTs) that evaluated biochemical response, virological response, histological response, and/or adverse reactions to combination therapy of interferon and ribavirin with and without Chinese herbs. The RR (relative risk) with a 95% confidence interval (CI) was calculated. Sensitivity analysis was conducted by omitting one study at a time. Publication bias among the eligible studies was evaluated by Egger's test. RESULTS A total of 17 RCTs matched the selection criteria. Overall, combination therapies of Chinese herbs plus interferon and ribavirin achieved significantly higher ALT (alanine transaminase) and ETVR (the end-of-treatment viral response), and significantly lower levels of HA (hyaluronic acid), LN (laminin), PC III (procollagen iii peptide), IV-C (type IV collagen), decreased LC (decreasing leukocyte count), ATF (abnormal thyroid function), psychosis, and anemia in CHC patients compared with those treated without Chinese herbs. Sensitivity analysis showed no changes and no potential publication bias was found. CONCLUSIONS The current evidence suggests that combination therapy of Chinese herb plus interferon and ribavirin yields better outcome and fewer adverse events in CHC patients than that of interferon plus ribavirin therapy.

Dietary supplement use among patients with hepatocellular carcinoma

BACKGROUND

More than 50% of US adults, and an even larger proportion of cancer patients, use dietary supplements. Since many supplements require hepatic metabolism, they may be particularly likely to cause toxicities in patients with hepatocellular carcinoma (HCC). However, little is known about supplement use in patients with HCC.

METHODS

From 2008 to 2012, we gave newly diagnosed HCC patients at our institution a standardized questionnaire about dietary supplement use, demographic factors, and clinical characteristics. We then followed patients for four years or until time to death to examine the relationship with supplement use.

RESULTS

Of 146 patients, 71% had used vitamins and 45% herbal supplements. Most commonly used supplements were antioxidants (51%), multivitamins (46%), vitamin D (25%), and milk thistle (23%). People in mid-higher income brackets were more likely to use herbal supplements (19% of those earning <$30 000, 50% of those earning $30 000-60 000, and 34% of those earning >$60 000 used supplements). Hepatitis C (HCV) patients were more likely to use milk thistle than those without HCV (30% vs 13%, P = .03), and patients with hepatitis B (HBV) were more likely than non-HBV patients to use vitamin C (32% vs 14%, P = .01). Supplement use was not associated with overall survival.

CONCLUSIONS

Like cancer patients in other studies, the majority of our HCC patients used dietary supplements. Supplement use was not associated with overall survival but should be studied in larger patient samples.
