ABSTRACT

BACKGROUND:

The increase of leukocyte and blood glucose levels is a kind of stress reaction when acute cerebrovascular disease occurs, it often occurs at the early clinical stage of acute cerebrovascular disease.

OBJECTIVE:

To observe the levels of leukocyte and blood glucose at the early stage of acute cerebrovascular disease, and investigate their correlation with recent prognosis.

DESIGN:

A prognostic analysis based on diagnosis taken patients as observational subjects.

SETTING:

Qingtian County People's Hospital.

PARTICIPANTS:

Totally 235 inpatients with acute cerebrovascular disease aged (63.13±9.55) years were selected from Qingtian County People's Hospital between May 2000 and May 2002, including 90 cases of cerebral hemorrhage (52 males and 38 females) aged (63.13±9.55) years and 145 cases of cerebral infarction (73 males and 72 females) aged (71.22±8.00) years. The disease course ≤ 1 month. According to the number of leukocytes, the patients were divided into normal leukocyte group (n=167) and increased leukocyte group (n=68). According to the level of blood glucose, they were divided into normal blood glucose group (n=146) and hyperglycemia group (n=89). The neurologic deficit score (NDS) of 0-15 points was taken as mild, 16-30 as moderate and 31-45as severe.

METHODS:

All the patients received cranial CT examination immediately after admission, and fasting venous blood samples were drawn on the next morning to detect the levels of leukocyte and fasting blood glucose. The x2 test was applied.MAIN OUTCOME

MEASURES:

① Comparison of age It was obviously higher in the cerebral infarction group than in the cerebral hemorrhage group [(71.22±8.00), (63.13±9.55) years, t=6.90, P ＜ 0.001]. ② Comparison of the percentage of disease types In the increased leukocyte group,the percentage of cerebral hemorrhage was obviously higher than that of cerebral infarction (66%, 34%, x2=31.47, P ＜ 0.005). In the hyperglycemia group, the percentage of cerebral hemorrhage was higher than that of cerebral infarction (51%, 49%, x2=9.12, P ＜ 0.005). ③ Comparison of the percentage of severe neurological impairment It was obviously higher in the increased leukocyte group than in the normal leukocyte group (26%, 6%,x2=21.12, P ＜ 0.005), also markedly higher in the hyperglycemia group than in the normal blood glucose group (27%, 5%, x2=21.70, P ＜ 0.005).④ Comparison of the percentage of death It was obviously higher in the increased leukocyte group than in the normal leukocyte group (31%, 6%,x2=26.15, P ＜ 0.005), also markedly higher in the hyperglycemia group than in the normal blood glucose group (26%, 5%, x2=20.02, P ＜ 0.005).

CONCLUSION:

Both the increase of leukocyte and blood glucose can damage the brain tissue, and can be used to judge the disease condition of patients with acute cerebrovascular disease, estimate the prognosis and guide the treatment.
