Description

HIV-infected patients may develop non-Hodgkin's malignant lymphoma, which is an AIDS-defining condition. Stebbing et al identified risk factors for occurrence of lymphoma in these patients. The authors are from the Imperial College of Science, Technology and Medicine and Chelsea and Westminster Hospital in London.


 

Parameters:

(1) age of the patient in years at entry to the cohort

(2) CD4 and CD8 lymphocyte counts

(3) antiretroviral therapy

 

Age of the patient at entry to the cohort: An age > 39 years was associated with decreased risk of developing lymphoma. The relative ratio decreases 1.02 for each year > 39 years (relative ratio = (-1.02 * ((age in years) - 39))

 

CD4 and CD* cell counts: The pattern of CD4 <= 200 per µL and CD8 < 595 per µL is associated with increased risk, with a relative ratio of 1.3.

 

Antiretroviral therapy:

(1) No antiretroviral therapy was associated with the greatest risk.

(2) Treatment with nucleoside analogues alone was associated with increased risk.

(3) A regimen that included a protease inhibitor (PI) and/or non-nucleoside reverse transcriptase inhibitor (NNRTI) showed a lower risk.

 

An HIV-positive patient with risk factors should be monitored more closely for development of malignant lymphoma. Ideally they should be treated with PI and/or NNRTI.
