Prediction of CD4+ ranges based on the total number of leukocytes in people living with HIV

Objective. To predict the amount of CD4+/μL3 in sequences of patient records with CD4 T lymphocyte values above 500 cells/μL3 and / or between 200 to 500 cells/μL3 from the absolute leukocyte count in the context of the theory of probability.

Materials and methods. Two mathematical inductions were performed to find predictive mathematical relationships for CD4+/μL3 when they are above 500 cells/μL3 and between 200 to 500 cells/μL3, from the absolute count of leukocytes. Subsequently, the probability of success of the predictions was calculated, two blind studies were performed on 80 remaining data, and sensitivity and specificity were calculated for both cases.

Results and discussion. If there are more than three records in time per patient, and these are above 500 CD4/μL3 cells or between 200 to 500 CD4/μL3 cells, finding that the absolute leukocyte count has a greater or equal value to three and lower to 4 for all the records, the following record will be maintained with a measurement of CD4 lymphocytes>500 or between [200, 500], if in the absolute count of leukocytes of the patient sequences a value of four is observed and CD4+ ranges from 200 to 500 cells/μL3, it can be deduced that there will be at least one measurement of CD4 +>500 cells/μL3 associated with a leukocyte measurement / μL3 greater than 3.7.

Conclusions. We established two temporal mathematical patterns capable of predicting the CD4+/μL3 count from the absolute leukocyte count.
