The choice to include the optimal protease inhibitor (PI) in highly active antiretroviral therapy (HAART) regimens in children with perinatal HIV-1 infection is still under debate. Virologic and immunologic outcomes of three different regimens in an observational paediatric cohort were compared. Data from 12 saquinavir-, 18 nelfinavir-, and 10 lopinavir/ritonavir-treated children were analyzed after 4 and 24 weeks of therapy. Immunologic and virologic outcomes were compared using multivariate analysis adjusting the results for age, baseline CD4+ T-lymphocyte count and baseline viral load. Saquinavir-treated children displayed significant reduction in viral load at week 24 (but not at week 4) and no increase in CD4+ T-lymphocyte count, indicating a poor advantage in using this drug. Lopinavir/ritonavir-treated children presented lower viral loads than nelfinavir-treated children at week 4 (P=0.020) and week 24 (p<0.0001). Virologic failure occurred in 6/18 (33.3%) nelfinavir-treated children but in no child receiving lopinavir/ritonavir (P=0.013). An undetectable viral load was achieved in 9/10 (90.0%) lopinavir/ritonavir- vs. 3/18 (16.6%) nelfinavir-treated children (p<0.0001). No significant difference in CD4+ T-lymphocyte count was observed between lopinavir/ritonavir- and nelfinavir-treated children at weeks 4 and 24. However, a different kinetic of the immunologic recovery was observed. Lopinavir/ritonavir-treated children displayed higher CD4+ T-lymphocyte counts than saquinavir-treated children since the first month of therapy (week 4: P=0.042; week 24: P= 0.029) while nelfinavir-treated children took 24 weeks to reach such an outcome (P=0.034). Since lopinavir/ritonavir-based regimen controls viral replication more efficiently and restores CD4+ T-lymphocyte count more quickly than saquinavir- or nelfinavir-based HAART, it may be considered when a salvage therapy or a rapid increase in CD4+ T-lymphocytes is necessary.

Viral Coinfection

Viral coinfection in the oral cavity associated to HIV infection was evaluated in 180 children from birth to 13 years of age of both sexes. The oral examinations were performed at the Pediatric AIDS Outpatient Clinic, São Lucas Hospital and Clinic Hospital, both in Porto Alegre, Brazil and at the School of Dental Medicine, University Hospital Center, State University of New York at Stony Brook, USA. The aim of this study was to identify the presence of viral infections in the oral cavity. PCR technique was used to determine opportunistic viral infections caused by CMV, EBV, and HSV in mucosal swabs. A high frequency of viral infection was detected in the oral cavity of HIV-infected children determined by the PCR technique. HIV-infected children with viruses had a favorable CD4+T lymphocyte count and unfavorable viral load.

Hematological Analysis

This study was carried out to determine the effect of herbal medication on the clinical status of HIV infected persons especially on their CD4+ T lymphocyte count and viral load. The toxicity of the medication was also studied. 25 HIV positive individuals were taken for the study. They were treated with a herbal formulation developed in our centre, for one year. Patients were evaluated for their clinical status every month and CD4+ T lymphocyte and viral load every six months. Other parameters assessed were body weight, hematological analysis and hepatic and renal function tests. Body weight was found to be increased in 20 patients out of 25 who have undergone treatment. CD4+T lymphocyte count was increased in 15 patients and viral load was decreased in 20 patients. In six patients viral load was undetectable range. Administration of these medications significantly reduced, elevated interferon-? and tumor necrosis factor in HIV patients. Medication did not produce any toxicity in HIV patients, as it did not show any significant change in hepatic function, renal function and haematology. Administration of herbal preparation was found to reduce clinical symptoms produced by HIV infection. This herbal formulation was found useful therapeutically for the management of HIV infection and did not produce any toxicity.

<p><strong>Backgrounds:</strong> As there is no published data regarding the response to Anti-retroviral therapy (ART) among HIV patients from Bangladesh. The present study was designed to determine the immunological and virological responses of HIV infected Bangladeshi adults starting ART. Objectives: To monitor the changes of CD4 and CD8 T-lymphocyte count and Viral load (VL) before and after three and six months of starting ART.</p><p><strong>Methods:</strong> 20 symptomatic HIV infected patients with CD4 T-lymphocyte count of &lt;350 cells/µ] of blood were initiated ART.CD4 and CDS T-lymphocyte counts were estimated by Flowcytometer and VL was dete1mined by real-time PCR technique.</p><p><strong>Results:</strong> The mean CD4 T-lymphocyte count among the sn1dy patients were 177±127 cells/µl before initiation of ART. After ART initiation, their mean CD4 count increased significantly to 368±181 and 452±183 cellshll after three and six months respectively (P&lt;0.0001).The mean CDS T-lymphocyte counts were 901±650 cells/µ! before initiation of ART, which increased to I 085±393 and 1121±372 cells/µl after three and six months respectively after ART initiation (P&gt;0.05). Before ART initiation, the mean VL was 5.25±1.19 log10 (copies/ml) among the study population which became undetectable in 15 (75%) patients after three months of ART and in another 2 (10%) patients after 6 months of ART initiation.</p><p><strong>Conclusion:</strong> Our study concluded that, ART is effective in slowing the progression of HIV infection to AIDS with good immunological and virological outcome among the ART initiators.</p>
