The team, led by Martin Markowitz from the Aaron Diamond AIDS Research Center, conducted a series of studies to assess correlates of immune activation..In an effort to promote better health outcomes for PWID, investigators, working in a three-institution multidisciplinary team, examined the relationship between injection drug use and immune activation in plastic manufacturers in china a sample of HIV infected and uninfected PWID. The investigators found the high prevalence of the hepatitis C virus among PWID made it difficult to distinguish between effects of IDU and active HCV infection.The participants for the study included people who were current and former injectors, and comparison participants who never injected."Harm reduction efforts for PWID should include treatment of HCV infection, to reduce immune activation and enhance related health benefits."However, an examination of the relationship between injection behaviors and immune activation, controlling for HCV viremia, found that while sharing injection equipment was not related to immune activation, frequency of injection and duration of injection were related to the immune markers studied."Cessation of injection resulted in a decline in immune activation.e.
A longitudinal study to test the impact of curing HCV on immune activation among PWID is underway by our group," said Dr.Washington D.: According to a new study, the use of heroin and illicit drugs triggers a response from the body's immune system.C.The team concluded by saying, "Further study to determine the mechanisms of the relationship between injection drug use behaviors and immune activation are needed in order to achieve the comprehensive understanding required to improve health of PWID.The researchers also examined three risk behaviours - sharing injection equipment; duration of injection frequency in years; and injection frequency over the past 30 days."The study is published in Journal of Acquired Immune Deficiency Syndromes.The results also suggest that harm reduction efforts to decrease injection frequency, without altogether stopping, can have positive effects towards reducing immune activation.To disentangle the effects of injection from HCV infection, the researchers compared immune markers between active PWID and individuals who had ceased injection (for one to four months)."Injection drug use (IDU), with or without HIV-infection, is associated with an increase in immune activation, measured in blood and in the GI tract," said co-investigator Sauarabh Mehandru.
