Fecal Microbiota Transplantation for Clostridium difficile Infection: A One-Center Experience.

BACKGROUND: Clostridium difficile is a gram-positive, anaerobic, and spore-forming bacillus, which is responsible for the majority of antibiotic-associated diarrhea and colitis. OBJECTIVE: Determine if fecal microbiota transplantation (FMT) is effective in a population sample from Connecticut. METHODS: We report the clinical experience of 92 consecutive patients from one gastroenterology practice in central Connecticut treated by colonoscopy with FMT for infection with Clostridium difficile from 2012 to 2017. The analyses are based on clinical follow-up up to 3 months after the FMT procedure and on medical chart review. RESULTS: Overall, complete recovery occurred in 86% of patients. As previously reported in a limited number of previous studies, community-acquired cases were more common than hospital-acquired cases, and community-acquired cases were more likely to be female. CONCLUSIONS: Consistent with some previous reports, we found the following: the source of the donor for FMT did not make a difference in recovery: material from nonrelatives was as effective as from close relatives; and the presence of multiple comorbidities did not make a difference in recovery: patients with 2 or more comorbidities did as well as those with one or none.

Impact of Cigarette Smoking Status on Pain Intensity Among Veterans With and Without Hepatitis C.

Objective: Chronic pain is a significant problem in patients living with hepatitis C virus (HCV). Tobacco smoking is an independent risk factor for high pain intensity among veterans. This study aims to examine the independent associations with smoking and HCV on pain intensity, as well as the interaction of smoking and HCV on the association with pain intensity. Design/Particpants: Cross-sectional analysis of a cohort study of veterans of Operations Enduring Freedom/Iraqi Freedom/New Dawn (OEF/OIF/OND) who had at least one visit to a Veterans Health Administration (VHA) primary care clinic between 2001 and 2014. Methods: HCV was identified using ICD-9 codes from electronic medical records (EMRs). Pain intensity, reported on a 0-10 numeric rating scale, was categorized as none/mild (0-3) and moderate/severe (4-10). Results: Among 654,841 OEF/OIF/OND veterans (median age [interquartile range] = 26 [23-36] years), 2,942 (0.4%) were diagnosed with HCV. Overall, moderate/severe pain intensity was reported in 36% of veterans, and 37% were current smokers. The adjusted odds of reporting moderate/severe pain intensity were 1.23 times higher (95% confidence interval [CI] = 1.14-1.33) for those with HCV and 1.26 times higher (95% CI = 1.25-1.28) for current smokers. In the interaction model, there was a significant Smoking Status × HCV interaction (P = 0.03). Among veterans with HCV, smoking had a significantly larger association with moderate/severe pain (adjusted odds ratio [OR] = 1.50, P < 0.001) than among veterans without HCV (adjusted OR = 1.26, P < 0.001). Conclusions: We found that current smoking is more strongly linked to pain intensity among veterans with HCV. Further investigations are needed to explore the impact of smoking status on pain and to promote smoking cessation and pain management in veterans with HCV.

Cigarette Smoking Status and Receipt of an Opioid Prescription Among Veterans of Recent Wars.

Objective: Cigarette smokers seeking treatment for chronic pain have higher rates of opioid use than nonsmokers. This study aims to examine whether veterans of Operations Enduring Freedom/Iraqi Freedom/New Dawn (OEF/OIF/OND) who smoke are more likely to receive an opioid prescription than nonsmokers, adjusting for current pain intensity. Design: Cross-sectional analysis of a cohort study of OEF/OIF/OND veterans who had at least one visit to a Veterans Health Administration primary care clinic between 2001 and 2012. Methods: Smoking status was defined as current, former, and never. Current pain intensity (+/- 30 days of smoking status), based on the 0-10 numeric rating scale, was categorized as no pain/mild (0-3) and moderate/severe (4-10). Opioid receipt was defined as at least one prescription filled +/- 30 days of smoking status. Results: We identified 406,954 OEF/OIF/OND veterans: The mean age was 30 years, 12.5% were women (n = 50,988), 66.3% reported no pain or mild pain intensity, 33.7% reported moderate or severe pain intensity, 37.2% were current smokers, and 16% were former smokers. Overall, 33,960 (8.3%) veterans received one or more opioid prescription. Current smoking (odds ratio [OR] = 1.56, 95% confidence interval [CI] = 1.52-1.61) and former smoking (OR = 1.27, 95% CI = 1.22-1.32) were associated with a higher likelihood of receipt of an opioid prescription compared with never smoking, after controlling for other covariates. Conclusions: We found an association between smoking status and receipt of an opioid prescription. The effect was stronger for current smokers than former smokers, highlighting the need to determine whether smoking cessation is associated with a reduction in opioid use among veterans.

Hepatitis C Virus: A Review of Treatment Guidelines, Cost-effectiveness, and Access to Therapy.

Hepatitis C virus (HCV) infection remains a significant medical concern in the United States and around the world. It is still one of the leading causes of chronic liver disease, and, for more than 20 years, there has been little progress in the treatment of HCV infection. The advent of direct-acting antivirals (DAAs) initiated the era of high efficacy and well-tolerated medications with high cure rates. The efficacy of these medications has prompted many professional societies around the world to update their treatment guidelines to include DAAs as first-line treatment. Guidelines by the American Association for the Study of Liver Disease/Infectious Disease Society of America, World Health Organization, Asian-Pacific Association for the Study of Liver and the European Association for the Study of Liver have all incorporated DAAs into their treatment guidelines. Despite the promising data supporting these medications, however, their cost represents a limiting factor to their use, even though studies have shown DAAs to be cost-effective. In addition to the expense of these medications and limited resources, there are many barriers preventing patients from receiving this potentially life-saving treatment. In order to overcome these barriers, these issues need to be recognized and addressed.

Dietary genistein induces sex-dependent effects on murine body weight, serum profiles, and vascular function of thoracic aortae.

BACKGROUND: The influence on, or interaction of, sex and dietary genistein on serum markers of cardiovascular health and cardiovascular function remain unclear. OBJECTIVES: Our purpose was to examine the effects of a genistein-containing diet (600 mg/kg food) (600G) and a genistein-free diet (0G), on cardiovascular risk parameters of male and female mice. METHODS: C57BL/6J mice were fed the diets for 1 month, after which time blood pressure, serum markers, and in vitro vascular reactivity was measured. RESULTS: Males fed the 600G diet gained significantly less weight than males fed the 0G diet (by 1.71 g); diet had no effect on female weight gain. Males fed the 600G diet also exhibited significantly elevated serum insulin (2.9 [0.5] vs 1.8 [0.4] ng/dL), and decreased serum glucose (0.15 [0.01] vs 0.24 [0.02] ng/dL) levels, resulting in a significant increase in the ratio of insulin to glucose; insulin and glucose levels were not changed by dietary genistein in females. Arterial pressure measurements from 0G-fed males were lower than other groups. However, basal vascular reactivity of isolated aortic rings was significantly increased by the 600G diet in both males (from 0.55 [0.03] to 0.94 [0.18] g) and females (from 0.45 [0.04] to 0.78 [0.09] g). Aortic wall thickness was not affected by diet. Norepinephrine-mediated contractility was also greater in aortic rings of male and female mice fed the 600G diet, and differences from the 0G diet persisted in the presence of L-NG-nitroarginine methyl ester but were completely accounted for by increased basal reactivity. CONCLUSION: Our data indicate that 1 month of a 600G or 0G diet significantly alters vascular function independent of sex. In contrast, sex-dependent differences exist in well-established serum markers of cardiovascular health and disease.
