Patients with HIV
HIV status at the time of their breast cancer diagnosis. The duration (median (IQR) of known HIV status prior to breast cancer diagnosis was 4 years. (0e9) years).
The HIV-infected patients had A23187 median (IQR) CD 4 count of 477 (287e670) cells/mm3 and 59.4% of patients on ARTs had a viral load below detectable levels (i.e. viral load below 50 copies/ml). Among patients with detectable viral loads, the median (IQR) viral load was 4757.5 (268.5e58609.5) copies/ml. The duration of seropositivity and ART use, CD 4 cell count and viral load were not associated with the clinical stage and pathological characteristics of the breast

Patients neurotransmitters had been diagnosed with HIV more than a year prior to their breast cancer diagnosis, and those on ART had lower viral loads and higher CD4 cell counts than other patients.
