Abstract:
Objective To investigate the change of renal tubular function in elderly patients after use of β lactam antibiotic. Methods The elderly patients with pulmonary infection were treated with β lactam antibiotic,the dosage was 50%-70% of normal use. The renal tubular function indicated by urine α1-MG, β2-MG, pro/Cre, NAG/Cre and glomerulus function marked by eGFR, serum creatinine (Cre)), cystatin C were detected during drugs treatment and 7 days after stopping medications. Results The infection was controlled well in 3-7 days after treatment. Urine α1-MG, β2-MG, pro/Cre and NAG/Cre were abnormal before treatment, were elevated in 3, 14 days after using antibiotic, and came down to the level before treatment on 7 days after stopping treatment. The level of Cre and eGFR was (89.0±25.97) μmol/L and (26.39±8.17) ml/min before treatment, then elevated and decreased in 14 days after treatment, respectively, and down to the level before treatment on 7 days after stopping of antibiotic. Cystatin c was abnormal before treatment and did not change significantly after treatment and after stopping antibiotic. Conclusions It is important to protect renal tubular function and to adjust antibiotic dosage according to eGFR during using antibiotic in elderly patients to control infection.
