title: [Study on the association of clinical characteristic, CD4+ and level of HIV viral load among 690 initial HIV-infection].
abstract: OBJECTIVE
  To understand the correlation between CD4+ cell count, HIV viral load (VL) and clinical characteristics among patients when HIV-1 was tested positive and initial AIDS diagnosis was made.
  
  
  METHODS
  690 HIV-infected cases from Beijing Di-Tan Hospital were included and under a cross sectional study while SPSS statistical method was used.
  
  
  RESULTS
  The 690 HIV-infected cases would include 458 males and 232 females with age range from 2-72 years (mean age as 35.3). The modes of transmission showed that: homosexual contact taking up 17.5% while heterosexual was 16.7%. Most of the homosexual-infected ones lived in Beijing and most of them had bachelor or master's degrees. 19.4% of the transmission happened between heterosexual/bisexual couples, suggesting that HIV was transmitted through the "bridge population" while the rest were infected by contaminated blood/plasma. Many of the cases were identified when they lately visited the pre-operation surveillance point in the hospital. Serious immunodeficiency symptoms or signs were discovered as: CD4+ count < 50 cell/microl, serious opportunistic infections including pneumocystosis pulmonary, cerebral toxoplasmosis and cryptococcal meningitis. Higher frequencies of diseases seen were dermotosis, pneumonia, upper respiratory tract infection, hepatitis and digestive tract moniliasis.
  
  
  CONCLUSIONS
  Because of the late identification of the disease, serious immuo-suppression situation often appeared, suggesting that there was an urgent need to improve STD/AIDS knowledge on those HIV (+) people so they might have an early access to accept medical care.
