In addition to HIV infection, factors at baseline associated with subsequent mortality were hypoleptinemia (p = 0.0002), low levels of HMW adiponectin (p = 0.0149), and high levels of PYY (p = 0.0087), IL2 (p = 0.0004), IL6 (p = 0.004), and TNF-α (p = 0.0203) (Table 7) [8]. Here, PYY is linked to HIV infectious disease.
