Abstract

Background: Hemodialysis patients are at risk of acquiring tuberculosis, which is most often due to reactivation of the
infection. As a result, screening for tuberculosis is recommended in hemodialysis patients. In this study, the rate of
response to cutaneous PPD along with tetanus and diphteria toxoid antigens have been evaluated to define in hemodialysis patients.
Materials and Methods: This clinical trial was conducted on 67 chronic hemodialysis patients in Labbafi Nejad Hospital
during March- May 2001. PPD, tetanus and diphtheria toxoid solutions, with 1/10 dilution were administered by Manteaux
technique and the induration was evaluated 48-72 hours, 7 and 9 days after.
Results: Of 64 patients, 18.8% had positive PPD tests and 26.6% had negative anergy tests through the first evaluation.
The degree of constancy in the results of PPD and anergy tests during the three-time evaluation period were 23.4% and
18.7%, respectively, and the degree of induration was increased or decreased among the rest.
Conclusion: Hemodialysis patients are at the increased risk for acquiring tuberculosis. Thus, negative cutaneous PPD
results should certainly be revised and evaluated using anergy tests and repetitive readings of the test results. Attention
must be paid to the “Delayed Type Hypersensitivity” (DTH) phenomenon presenting for the first time in the analysis of
cutaneous test results. Finally, it is recommended to reconsider the value of cutaneous PPD test and its method of
analysis in hemodialysis patients. (Tanaffos 2002; 1(2): 21-26)
