Randomized Controlled Trial Multicenter Study
Diet low in FODMAPs reduces symptoms of irritable bowel syndrome as well as traditional dietary advice: a randomized controlled trial.
A diet with reduced content of fermentable short-chain carbohydrates (fermentable oligo-, di-, monosaccharides, and polyols [FODMAPs]) has been reported to be effective in the treatment of patients with irritable bowel syndrome (IBS). However, there is no evidence of its superiority to traditional dietary advice for these patients. We compared the effects of a diet low in FODMAPs with traditional dietary advice in a randomized controlled trial of patients with IBS. ⋯ A diet low in FODMAPs reduces IBS symptoms as well as traditional IBS dietary advice. Combining elements from these 2 strategies might further reduce symptoms of IBS. ClinicalTrials.gov ID NCT02107625.

We conducted an open-label, randomized, phase 3 trial to determine the efficacy and safety of sofosbuvir and ribavirin, with and without peginterferon-alfa, in treatment-experienced patients with cirrhosis and hepatitis C virus (HCV) genotype 2 infection and treatment-naïve or treatment-experienced patients with HCV genotype 3 infection. ⋯ Among patients with genotype 3 HCV infection, including a large proportion of treatment-experienced patients with cirrhosis, the combination of sofosbuvir, peginterferon, and ribavirin for 12 weeks produces high rates of SVR. Treatment-experienced patients with cirrhosis and genotype 2 HCV infection had high rates of SVR in all groups. EudraCT ID 2013-002641-11.

Multicenter Study
Efficacy of ledipasvir and sofosbuvir, with or without ribavirin, for 12 weeks in patients with HCV genotype 3 or 6 infection.
We performed a phase 2 clinical trial to evaluate the efficacy and safety of ledipasvir and sofosbuvir, with or without ribavirin, in patients infected with hepatitis C virus (HCV) genotype 3 or 6. ⋯ In an uncontrolled, open-label trial, high rates of SVR12 were achieved by patients with HCV genotype 3 infection who received 12 weeks of ledipasvir and sofosbuvir plus ribavirin, and by patients with HCV genotype 6 infection who received 12 weeks of sofosbuvir and ledipasvir without ribavirin. Current guidelines do not recommend the use of ledipasvir and sofosbuvir, with or without ribavirin, in patients with HCV genotype 3 infection. ClinicalTrials.gov Number: NCT01826981.

Clinical Trial
Incidence and mortality of colorectal cancer in individuals with a family history of colorectal cancer.
Little is known about the change in risk conferred by family history of colorectal cancer (CRC) as a person ages. We evaluated the effect of family history on CRC incidence and mortality after 55 years of age, when the risk of early onset cancer had passed. ⋯ After 55 years of age, subjects with 1 FDR with CRC had only a modest increase in risk for CRC incidence and death; age of onset in the FDR was not significantly associated with risk. Individuals with ≥2 FDRs with CRC had continued increased risk in older age. Guidelines and clinical practice for subjects with a family history of CRC should be modified to align CRC testing to risk. ClinicalTrials.gov number, NCT00002540.

Sofosbuvir and daclatasvir are direct-acting antiviral drugs used to treat chronic hepatitis C virus infection. In 2015, the Food and Drug Administration and European Medical Agency warned that bradycardia could occur when amiodarone was administered in combination with sofosbuvir, but no case reports had been published. We report extreme bradycardia within 2 hrs after intake of sofosbuvir and daclatasvir by 2 patients receiving amiodarone. ⋯ Administration of sofosbuvir and daclatasvir on day 13 induced bradycardia 2 hrs after intake. However, no bradycardia occurred following a rechallenge 8 weeks after the patient stopped taking amiodarone. These observations indicate that patients treated with amiodarone should be continuously monitored within the first 48 hrs following the initiation of sofosbuvir and daclatasvir.
