Assessment on depressive status and the therapeutic effects of highly active antiretroviral therapy among anti-HIV-1(+) population / 中华流行病学杂志

<p><b>OBJECTIVE</b>To assess the depressive status and its influence on Chinese HIV-1(+) population, and how it was influenced by highly active antiretroviral therapy (HAART) and the CD4(+) T cell count.</p><p><b>METHODS</b>Anti-HIV-1(+) patients (age between 18 and 65 years old) who had met the criteria to commence the anti-HIV treatment but had not yet started, were selected from the Beijing Ditan Hospital between March 2011 and June 2012. BDI-II (Beck Depression Inventory) and a self-designed questionnaire were used to evaluate the baseline and the status of 48 weeks post the HAART treatment. Statistically, t test and the Wilcoxon rank sum test were used to compare the BDI scores under different conditions and before/after the HAART.</p><p><b>RESULTS</b>(1) Of 100 subjects: male to female ratio was 99:1; the average age was 31.37 ± 5.58 years; the average education background was of 13.13 ± 3.51 years; the unemployed percentage was 4%; time before being identified as anti-HIV-1(+) was 5.0 (1.0 - 21.0) months; the percentage being infected through homosexual contact was 83%. The baseline BDI score was 6.0 (3 - 10.25). (2) There was no significant difference (P > 0.05) in BDI score between those subjects having had education less or more than 12 years; the BDI score of patients whose anti-HIV-1(+) was significantly higher (P < 0.05) among those discovered within the past 6 months than those more than 6 months. The BDI score of patients whose baseline CD4(+) T cell count below 200 cells/µl was significantly higher (P < 0.05) than those with baseline CD4(+) T cell count greater than 200 cells/µl. The CD4(+) T cell count was significantly high (P < 0.001) after 48 weeks of anti-viral treatment, but the BDI score was not significantly different (P > 0.05). There was no significant change (P > 0.05) in the proportion of patients with different degrees of BDI score before and after 48 weeks of antiviral treatment.</p><p><b>CONCLUSION</b>Depression in HIV patients was most overt in the first six months when they were aware of the infection. The degree of depression was more severe in patients with baseline CD4(+) T cell count less than 200 cells/µl with improvement of immunity after the HAART did not alleviate the level of depression.</p>

Impact of highly active antiretroviral therapy on plasma MCP-1 and MSP in AIDS patients / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To study the effect of highly active antiretroviral therapy (HAART) on plasma levels of MSP and MCP-1 in AIDS patients.</p><p><b>METHODS</b>Forty Chinese AIDS patients were treated with HAART for 3 months and 84 German AIDS patients with HAART for 3 to 6 years. The pre-treatment and post-treatment plasma levels of MSP and MCP-1 were measured by enzyme-linked immunosorbent assay (ELISA), and their correlations with CD4+ cell counts and viral loads were analyzed.</p><p><b>RESULT</b>The mean levels of MCP-1 were significantly higher and MSP were significantly lower in HIV-infected patients compared with the HIV-negative controls (P <0.01). After HAART for three months, there were no significant changes in the levels of these cytokines. But after long-term HAART (for 3 to 6 y), the level of MCP-1 was increased and that of MSP decreased significantly (P<0.01). There was a negative correlation between MSP and MCP-1 levels, and the same for MSP level and CD4+ cell counts; while there was a positive correlation between MCP-1 levels and CD4+ cell counts.</p><p><b>CONCLUSION</b>The changed plasma levels of MSP and MCP-1 are associated with HIV-1 infection and HAART may reverse the levels of these two cytokines.</p>
