ER Niacin/Laropiprant Impact on Cardiovascular Markers and Atheroprogression in HIV-infected Individuals on cART

HIV-infected patients are at increased risk for cardiovascular disease. Large investigations support an inverse correlation between HDL-C levels and coronary heart disease. Therefore a treatment lowering HDL-C such as niacin could reduce the risk of atheroprogression not only through its benefit in terms of lipid profile, but also by reducing atherosclerotic inflammation.
The study aims at showing that a therapy targeting HDL-C increase in HIV-infected patients on suppressive cART has the potential for reducing subclinical atherosclerotic inflammation associated with HIV itself in HIV-individuals on cART.
NILACH is a randomised, multicenter, double blind, placebo controlled, 48 weeks trial to test the effect of the newly marketed niacin/laropiprant on carotid intima-media thickness (IMT) in 90 subjects.
Regimen 1: ER niacin/laropiprant 1g/20 mg for the first 4 weeks and 2g/40mg from week 5 to the end of the study (the titration aims to reduce adverse reactions)
Regimen 2: ER niacin/laropiprant placebo p.m.
The primary end point is the change in mean common carotid intima-media thickness from baseline and 48 weeks, compared between the niacin/laropiprant group and the placebo group.
The proposed in vivo experiments should provide insights on the potential benefits of niacin treatment of cardiovascular disease in HIV patients. In addition, we will be able to further clarify the role of systemic inflammatory mediators in the development of early atherosclerosis of HIV-infected patients on antiretroviral therapy. Detection and treatment of non-infectious co-morbidities such as cardiovascular diseases have become essential for HIV-infected individuals exposed to lifelong antiretroviral therapy and go beyond mere management of opportunistic infections or virologic suppression.

Efficacy of time restricted eating and resistance training on body composition and mood profiles among young adults with overweight/obesity: a randomized controlled trial

Article

Author: Ye, Weibing ; Cui, Tingting ; Liu, Yubo ; Korivi, Mallikarjuna ; Sun, Yichao

BACKGROUND/OBJECTIVE:

Dietary restriction or exercise regimens can promote weight loss or physical fitness among patients with obesity. However, intervention-associated adverse effects may impede patients' motivation to participate in dietary/exercise interventions. We examined the effects of time restricted eating (TRE) with or without resistance training (RT) on body composition, mood profile, and sleep quality in young college adults with overweight or obesity.

METHODS:

Fifty-four young college students with overweight/obesity were randomized into control (CON), TRE, RT, and TRE plus RT (TRE+RT) trials. The TRE trials restricted to an eating window of 10-hour/day for 8-week. The RT trials performed supervised resistance exercise, while the control trial maintained a regular lifestyle. Changes in body composition variables, blood pressure, mood status, and sleep quality were measured before and after the intervention.

RESULTS:

TRE intervention alone or in combination with RT significantly (p < 0.01) decreased body weight (>2 kg) and BMI (~1 kg/m²) in adults with overweight/obesity. Both RT alone and combined with TRE substantially decreased fat mass by 1.1 ± 0.5 and 3.2 ± 0.4 kg, respectively. The decreased fat mass was greater in the combination trial than in the RT trial, whereas TRE alone had no effect. In contrast, fat-free mass was significantly (p < 0.01) decreased with TRE (-2.3 ± 06 kg), increased with RT (1.6 ± 0.3 kg), and was stably maintained with combination interventions. The reduced waist and hip circumferences in the TRE (p < 0.01) were similar to those in the TRE+RT trials, however, RT alone had no effect. Time and group interaction showed a large effect size (partial eta squared) for all body composition variables. In addition, RT with or without TRE notably decreased diastolic blood pressure (RT: -5.5 ± 1.9 mmHg, TRE+RT: -4.1 ± 1.5 mmHg, p < 0.05). Mild anxiety levels at baseline in RT (4.8 ± 2.6) and TRE+RT (4.1 ± 3) trials were found to be normal at postintervention in TRE+RT (3.6 ± 1.7) but not in RT (5.6 ± 3.5). No depression or stress was recorded among the participants during the intervention. The reported poor sleep quality among participants at baseline was significantly improved with RT (4.8 ± 2.9; p < 0.05), and tended to improve with TRE+RT interventions (4.5 ± 1.9).

CONCLUSIONS:

10-hour TRE is beneficial for weight/fat loss without affecting mood status. However, TRE combined with RT might be more effective for weight/fat loss, maintaining muscle mass, and good quality of sleep among young adults with overweight or obesity.

Time-restricted eating and autosomal dominant polycystic kidney disease: a pilot, randomized clinical trial

Article

Author: George, Diana ; Thomas, Elizabeth ; Chonchol, Michel ; Ramanathan, Sumana ; Wang, Wei ; Steele, Cortney ; Ostrow, Anna ; Coleman, Erin ; Gregory, Adriana ; Kline, Timothy L ; Nowak, Kristen L ; Bing, Kristen ; Gitomer, Berenice Y

ABSTRACT:

Background:

Autosomal dominant polycystic kidney disease (ADPKD) is the most commonly inherited progressive kidney disease. Time-restricted eating (TRE) is a fasting regimen that restricts eating to a particular window (typically 8 hours/day), which could slow cyst growth based on preclinical models.

Methods:

A 12-month, randomized, controlled, behavioral dietary intervention compared TRE with a control group given healthy eating advice without TRE (HE), without caloric restriction. Participants underwent baseline and 12-month measurements, including adherence (percentage of participants adhering to the 8-hour window; primary outcome), and MRI to determine height-adjusted total kidney volume (htTKV) and adiposity.

Results:

Twenty-nine participants (23 females, mean standard ± deviation 48 ± 9 years) with a body mass index of 31.1±5 kg/m2 were randomized to TRE (n = 14) or HE (n = 15). Of the total participants, 71% (n = 10) of TRE and 87% (n = 13) of HE participants completed the intervention. The eating window was 9.6 ± 3.6 hours for TRE (60% achieving the 8-hour window) and 12.0 ± 2.0 for HE groups (P = .07). At month 12, both groups lost modest weight (−2.4 ± 6.4% and −3.6 ± 5.4% in the TRE and HE groups, respectively). Annual change in htTKV was 3.0 ± 8.5% and 4.6 ± 8.8% in the TRE and HE groups, respectively. Both change in weight (r = 0.67, P < .01) and change in visceral adiposity (r = 0.54, P < .01) were positively correlated with change in htTKV.

Conclusion:

Both the TRE and HE group lost modest weight at 12 months. The targeted TRE adherence of ≥75% of participants was not achieved. Weight and adiposity loss may be more important drivers of kidney growth than the timing of eating.

Time-restricted eating to address persistent cancer-related fatigue among cancer survivors: a randomized controlled trial

Article

Author: Zhu, Shijun ; Quick, Lauren ; Youngblood, Shari M ; Kleckner, Amber S ; Manoogian, Emily N C ; Clingan, Carin L ; Elrod, Rebecca D ; Kleckner, Ian R ; Badros, Ashraf Z ; Emadi, Ashkan ; Panda, Satchidananda

PURPOSE:

Time-restricted eating (TRE) helps regulate rest-activity rhythms, blood glucose, and other diurnally regulated energetics processes, which may have implications for persistent fatigue. In a randomized controlled trial, we tested the effects of TRE vs. control on fatigue in cancer survivorship.

METHODS:

Adult cancer survivors were recruited who were 2 months to 2 years post-treatment and reported moderate to severe fatigue. Participants were randomized 1:1, TRE:control, and all received individualized nutrition counseling. The TRE group self-selected a 10-h eating window for 12 weeks. At baseline, week 6, and week 12, participants were asked to log eating instances, complete the Functional Assessment of Chronic Illness Therapy-Fatigue questionnaire (FACIT-F, higher score = less fatigue), and wear an actigraph and continuous glucose monitor.

RESULTS:

Thirty participants completed baseline assessments and were randomized (77% female, 53% Black/African American, 43% White, 7% Hispanic; 54.1 ± 14.7 years old; 87% with blood cancer); 25 completed 12-week assessments. TRE led to a meaningful reduction in fatigue at week 12 controlling for baseline levels (change in FACIT-F fatigue subscale = 0.0 ± 5.4 for control, 4.1 ± 5.7 for TRE, p = 0.11, effect size (ES) = 0.70; clinically meaningful threshold = 3.0 points). Glucose parameters (e.g., average interstitial glucose, average fasting glucose) tended to be lower, and rest-activity rhythms tended to indicate more regularity for those in the TRE vs. control group at weeks 6 and 12, though differences were not statistically significant (p > 0.19).

CONCLUSIONS:

A 12-week, nutritionist-led TRE program led to less fatigue than control. Continued study of TRE patterns are warranted to optimize this eating pattern and address persistent cancer-related fatigue.

FDA sends warning letter to Merck & Co over vaccines plant

Merck & Co’s week of woe has continued with the news that US regulators have told the firm to correct what are described as “numerous manufacturing deficiencies” at its main vaccines plant. The US Food and Drug Administration has issued a warning letter to Merck having conducted an inspection of the firm’s West Point, Pennsylvania facility between November 26, 2007 and January 17 this year. The agency’s investigators say they documented “significant deviations from current good manufacturing practice” at the plant in the manufacture of vaccine products, bulk drug substances and drug components. The products manufactured at the West Point site include Merck & Co’s cervical cancer vaccine Gardasil and ProQuad, its combination jab against measles, mumps, rubella and chicken pox. Also produced at the facility are the Haemophilus influenzae type B vaccine PedvaxHIB and ComVax for haemophilius b and hepatitis B and 1.2 million doses of these two jabs were voluntarily recalled in December because Merck said it could not assure sterility of those specific vaccine lots. The warning letter, which is posted on the FDA’s website in a heavily edited form, has been issued because Merck's response to the FDA’s initial inspection report was "inadequate to address the serious deviations noted”. Most of the myriad complaints appear to deal with procedural errors but the agency stresses it "does not believe that the issues identified will affect the safety of the vaccines" made at the facility. Merck says that it is committed to working with the FDA to address these issues, adding that it does not distribute contaminated products and is confident in their “quality, effectiveness and safety”. The letter comes in a week when Merck’s stock has taken a bashing after the FDA rejected applications firstly for a proposed fixed combination of Singulair (montelukast) and S-P’s Claritin (loratadine) as a treatment for allergic rhinitis and secondly for its new cholesterol compound MK-0524A (extended-release niacin/laropiprant).
