Inflammation linked to intensity of tobacco smoking among HIV-positive people Inflammation in the body has been linked to the intensity of tobacco smoking among people with HIV, according to a team of University of Massachusetts Amherst researchers. Krishna Poudel, associate professor of community health education in the School of Public Health and Health Sciences, and colleagues reported positive linear relationships between intensity, duration and pack-years of smoking and inflammation in HIV-positive people. They believe it to be the first, more thorough examination of specific smoking-related variables with the levels of inflammation in this group, while also taking into account highly active antiretroviral therapy (HAART) and other important factors.
