Acquired immune deficiency syndrome（ AIDS） with pulmonary infection has become the main condition of AIDS patients with opportunistic infections

and it has become one of the primary causes of death among AIDS patients. From the view of traditional Chinese medicine

the clinical research on AIDS with pulmonary infection is discussed

and the etiology and pathogenesis

syndrome differentiation

and influencing factors related to syndrome types of the disease are analyzed. The authors think that there are complicated pathological factors in AIDS with pulmonary infection. Syndrome differentiation method

such as Zang-Fu

Qi-Blood

and Yin-Yang differentiation should be taken into consideration in the process of clinical syndrome differentiation

combining with disease staging. The pathogenesis of the disease involves many organs

including the lungs

spleen and kidney

and Qi-blood deficiency is one of the characteristics. Phlegm

deficiency and damp are still its important pathological factors. In the early stage of pulmonary infection

both defensive-Qi and evil-Qi are sufficient

which often cause phlegm-heat obstructing lung syndrome. With the weakness of Qi-blood function of organs

phlegm-damp obstructing lung syndrome occurs. In the later period of the disease

many organs are damaged

that often leading to lung and kidney deficiency syndrome. Distribution of syndrome types in AIDS with pulmonary infection is influenced by many factors

such as geographic regions

gender

route of infection

etc. which should be considered comprehensively in the process of clinical syndrome differentiation.
