Abstract:
Objective To explore the value of CD+4T lymphocyte count in laboratory diagnosis of AIDS complicated with pulmonary tuberculosis.Methods Forty-three patients with acute tuberculosis were selected as the subjects.Among them,14 patients had typical tuberculosis(X-ray or chest CT),29 cases were atypical tuberculosis(X-ray or chest CT).43 patients were examined by CD+4T lymphocyte count,sputum smear tuberculosis acid-fast bacilli test and T-SPOT.TB(interferon-γ release test),and the results of various methods were compared.Results The The number of CD+4T lymphocytes in patients with typical pulmonary tuberculosis was (151.26±59.47)/μL,and that in atypical pulmonary tuberculosis was (69.11±19.65)/μL,the difference was statistically significant(t=5.124,P<0.05);and with the reduction of CD+4T lymphocytes,AIDS patients showed more atypical pulmonary tuberculosis.The positive detection rates of CD+4T lymphocyte count,T-SPOT.TB and sputum smear were 86.05%,16.28% and 51.16% respectively.The positive rate of combined detection of three methods(90.70%) was significantly higher,the differences were statistically significant(x2=5.123,6.023,7.125,all P<0.05).Conclusion CD+4T lymphocyte count is of great value in the laboratory diagnosis of AIDS complicated with tuberculosis,and it is worthy to be widely carried out in clinical practice.
