Influenza Vaccine in Elderly: Nutritional Status-Dependent Immunogenicity

influenza vaccine

The immune response to influenza vaccine is attenuated in elderly persons, though they are at greatest risk for morbidity and mortality by influenza virus infection. Experimental studies demonstrate that co-administration of L-cystine and L-theanine enhanced antigen-specific production of immunoglobulin in aged mice infected with influenza virus. This study thus investigated the effect of L-cystine and L-theanine on antibody induction by influenza vaccines in elderly persons.

Attenuation of Natural Killer T-Cells with Cystine and Theanine

Men who perform resistance training 3 times a week for at least 6 months tend to have lower T-helper cell counts than non–resistance trained men. In addition, the natural killer (NK) cell count, an index of innate immunity, has been shown to decrease below the resting value after submaximal resistance exercise in both resistance-trained and non–resistance-trained men. It is a common hypothesis that resistance training impairs the immune system rather than enhancing its functions. This study examined the affects of cystine and theanine on NK cells, inflammation and immunity.

Double-blind, Randomized Trial on Cystine, Theanine and the Common Cold

The common cold, an acute infection properly known as “cold syndrome,” is the most common human illness. The majority of cases of cold syndrome are acute infections of the upper respiratory tract, and its major cause is viral infection. Conventional methods of treatment use medications, such as analgesic agents and antihistamines, but these are only effective for the alleviation of symptoms, such as sneezing and runny nose. The incidence of subjects with colds during this trial was significantly lower in the CT group than in the placebo group, although the duration of the colds was not significantly different between the groups. These results suggest that CT supplementation may be useful for the prevention of the common cold.

Interview with Bernard Bihari, MD: Low-dose Naltrexone for Normalizing Immune System Function

  Introduction   Bernard Bihari, MD, (1931-2010) was the discoverer of the clinical effects of low-dose naltrexone (LDN) in humans. In his groundbreaking clinical trial of patients with HIV/AIDS at Downstate Medical Center in 1985-86, Dr Bihari discovered the significant effectiveness of low-dose naltrexone in protecting the battered immune systems
