【Objective】This study aimed to determine whether the recovery period from pneumonia might be correlated with the CD4 lymphocyte count or other general blood test parameters in patients aged 60 years or older.【Methods】Routine blood counts with additional test parameters, including the CD4 lymphocyte count, were performed on admission or immediately after in 104 patients aged 60 years or older who were hospitalized for treatment of community-acquired pneumonia from October 2005, in order to examine whether the duration of treatment with antibiotics(considered to represent the recovery period from pneumonia)was correlated with the CD4 lymphocyte count or other general blood test parameters.【Results】The CD4 lymphocyte counts were significantly reduced in patients who died of pneumonia(non-survivor group, n=10)as compared with those among the patients who recovered from the pneumonia(recovery group, n=94)and normal individuals(normal group, n=68)(208±51/μl vs. 520±34/μl and 812±67/μl, respectively;p<0.01). However, there was no correlation between the CD4 lymphocyte count and the recovery period from pneumonia in the recovery group(p=0.09, r=0.16). The serum Alb level was significantly reduced in the non-survivor group as compared with the values in the recovery and normal groups(2.65±0.11g/dl vs. 3.30±0.06g/dl and 3.98±0.04g/dl, respectively;p<0.01). The serum Alb was correlated with the recovery period from pneumonia in the recovery group(p<0.01).【Conclusions】Pneumonia is more likely to become severe in patients with lower CD4 lymphocyte counts, and may also follow a protracted course and become severe in patients with low serum Alb levels.
