Abstract

Objective: The present study attempts to determine normal values of CD4, CD8, CD4/CD8 ratio, total WBC and differential counts, hematocrit and total lymphocyte count (TLC) in healthy HIV sero-negative and sero-positive subjects, and to assess the prognostic significance of these parameters in these subjects as compared to AIDS subjects. Material and Methods: A total of 300 subjects (147 M, 153 F) aged between 17 and 71 years were recruited into the study. Subjects were separated according to sex and divided into three groups: Group A: healthy HIV sero-negative subjects; Group B: healthy HIV sero-positive newly diagnosed ART-naïve subjects; and Group C: AIDS subjects. CD4 and CD8 counts were determined by flow cytometry; hematocrit was determined using Hawksley micro-capillary tubes; total WBC and differential counts were determined manually with the improved Neubauer counting chamber; and TLC was obtained by multiplying the percentage of lymphocytes by the total WBC count. Results: For male subjects, significant differences were found in CD4 count, CD4/CD8 count ratio, hematocrit, total WBC and TLC, whereas for female subjects, significant differences were found only in CD4 and CD4/CD8 count ratio in the three groups of subjects. In both sexes, however, these parameters were found to be highest in healthy HIV sero-negative subjects and lowest in AIDS subjects, with HIV sero-positive subjects having intermediate values. Conclusion: The results confirm previous reports that the CD4 count and CD4/CD8 count ratio are fairly reliable indicators of the progression of HIV infection. In addition, the results also apparently suggest that the prognostic value of CD8 count is limited and that of TLC possibly sex-dependent. The results could be of importance in our environment since previous reports have been relatively scarce.

Özet

Amaç: Bu çalışmanın amacı sağlıklı HIV seronegatif ve seropozitif olgularda normal CD4, CD8 değerleri, CD4/CD8 oranı, total lökosit ve periferik yaymadaki kan hücrelerinin sayımları hematokrit ve total lenfosit sayımının (TLS) tespit edilmesi ve AIDS olgularına kıyasla bu kişilerde söz konusu parametrelerin prognostik öneminin değerlendirilmesidir. Yöntem ve Gereçler: Onyedi ile 71 yaş aralığındaki toplam 300 olgu (147 E, 153 K) çalışmaya alınmıştır. Olgular cinsiyete göre ayrılmış ve üç gruba bölünmüştür: Grup A: Sağlıklı HIV seronegatif olgular; Grup B: sağlıklı HIV seropozitif (yeni teşhis edilmiş ART-naïve) olgular; ve Grup C: AIDS olguları. CD4 ve CD8 sayımları akış sitometrisi ile; hematokrit Hawksley mikro-kapiler tüpler ile; total lökosit ve periferik yaymadaki kan hücrelerinin sayımları geliştirilmiş Neubauer sayım kabı kullanılarak manuel olarak tespit edilmiş ve TLS de lenfosit yüzdesinin toplam lökosit sayımı ile çarpılmasıyla elde edilmiştir. Bulgular: Üç çalışma grubunda erkek olgularla ilgili olarak CD4 sayımı, CD4/CD8 sayımının oranı, hematokrit, toplam lokösit ve toplam lenfosit sayımına yönelik anlamlı farklılıklar gözlemlenirken kadın olgularda yalnızca CD4 sayımı ve CD4/CD8 oranında anlamlı farklılıklar bulunmuştur. Ancak her iki cinsiyete yönelik olarak bu parametrelerin en yüksek değerleri HIV seronegatif olgularda ve en düşük değerleri de AIDS olgularında gözlenmiştir. HIV seropozitif olgular ise ara değerlere sahiptir. Sonuç: Elde edilen sonuçlar ile CD4 sayımı ve CD4/CD8 oranının, HIV enfeksiyonunun gelişimine yönelik oldukça güvenilir göstergeler olduğuna dair önceki raporlar onaylanmaktadır. Ayrıca elde edilen sonuçlar ile, CD8 sayımı prognostik değerinin sınırlı olduğu ve toplam lenfosit sayımının ilgili değerinin ise cinsiyete bağlı olduğu açıkça ileri sürülmektedir. Önceki raporlar nispeten sınırlı olduğundan elde edilen sonuçlar son derece önem taşımaktadır.
