His CD4 count was only drawn once prior to initiating multidrug therapy just over 3 weeks later and was only slightly depressed at 407 cell/μL. While this is well above the typical threshold of less than 100 cells/μL seen in ADRs to TMP-SMX, his viral load was markedly elevated at 9,645,190 copies/μL. Primary HIV can present with similar cutaneous and mucosal findings even in the absence of an ADR; however, it is typically accompanied by fever and lymphadenitis and presents in the first week of illness, none of which were seen in this patient [12]. The gene discussed is CD4; the disease is lymphadenitis.
