Possible reasons for not starting HAART included: 7 cases had CD4+ lymphocyte count ≥200 cells/mm3 (all survived); 3 cases defaulted from TB treatment (all survived); 10 cases died within 15 days after TB diagnosis; 8 cases had other conditions (3 with abnormal liver function because of liver cirrhosis; 2 with cancer; 1 committed suicide; 1 had severe sepsis; and 1 had personal reasons; all of them died). This evidence concerns the gene CD4 and tuberculosis.
