Summary The genesis and development of tumor are closely connected with immune system and neuroendocrine system. To investigate the changes of neuroendocrine and immune system in leukemia patients and their probable connection with leukemia, we studied five groups of patients including leukemia patients with normal temperature, leukemia patients with high temperature and infection (high‐leukocyte count group and low leukocyte count group), general patients with fever and healthy Chinese adult blood donors as control group. We determined their blood cell counts by blood count meter, determined their arginine vasopressin (AVP) levels in blood plasma by radioimmunoassay and their cross‐reacting protein (CRP), and lipopolysaccharide (LPS) levels by immunoturbidimetry. Then we studied the difference and association among these indexes. Our results revealed a significant increase of AVP, LPS, and CRP levels in the blood of leukemia patients with normal temperature vs. normal people; Individual leukemia patients had high AVP levels although they had normal LPS and CRP levels; In the group of leukemia patients with high temperature and low leukocyte counts, the CRP level is significantly higher than some of other groups, while there was no significant increase in its AVP level. We conclude that no matter the temperature is normal or not, there were always neuroendocrine disturbance, inflammation, and inapparent infection in leukemia patient; To the leukemia patients with low leukocyte counts, the relationship between inflammation and neuroendocrine is more complicated.
