【摘要】 目的 研究人类免疫缺陷病毒(HIV)感染者和获得性免疫缺陷综合症(AIDS)患者CD4+T淋巴细胞数变化(ΔCD4+T)和外周血淋巴细胞总数变化(ΔTLC)的相关性。探讨用ΔTLC预测ΔCD4+T在监测HIV/AIDS患者疾病进展以及高效抗逆转录病毒治疗(HAART)疗效的价值。 方法 回顾性分析2005〖CD3/5〗2008年确诊的91例HIV/AIDS患者的临床资料。 结果 ΔTLC与ΔCD4+T呈直线正相关(r=0809,Plt;001),好于TLC与CD4+T的相关性(r=0712,Plt;001)。分别用ΔTLC 170、330、630、910个/μL细胞预测ΔCD4+T 50、100、200、300个/μL细胞时具有较好的预测价值,各项评价指标符合率基本达到90%以上,显著高于相同时间下用TLC预测CD4+T计数的价值。 结论 应用ΔTLC预测ΔCD4+T,可比TLC更加直观、准确的反映HIV感染者疾病进展和评价AIDS患者HAART的疗效。【Abstract 】Objective To assess the utility of total lymphocyte count (TLC) changes (ΔTLC) in place of TLC to predict the development of HIV/AIDS. To investigate the monitoring value of ΔCD4+T on progress of HIV/AIDS and HAART which predicted by ΔTLC. Methods Clinical data of 91 patiens with HIV/AIDS diagnosed from 2005 to 2009 were retrospectively analyzed. Results A linear correlation was found between the value of ΔTLC and the value of CD4+T changes(ΔCD4+T)(r=0809,Plt;001),which was better than the correlation between TLC and CD4+T (r=0712,Plt;001).Using ΔTLC as 170,330,630,910 cells/μL,respectively for forecasting ΔCD4+T as 50,100,200,300 cells/μL,respectively,had a better predictive value with the area under ROC curve near to 09,significantly higher than using TLC for predicting CD4+T counts. Conclusion ΔTLC is more accurate than TLC to reflect the development of HIV/AIDS.
ObjectiveTo summarize the clinical, radiological and pathological characteristics of acquired immune deficiency syndrome (AIDS) combined with Pneumocystis carinii pneumonia (PCP), so as to improve the clinicians' understanding of the disease. MethodsThe clinical data of 50 AIDS patients combined with PCP admitted between February 2006 and May 2015 were retrospectively analyzed, including medical history, physical signs, laboratory examination, chest high resolution CT (HRCT), pathological characteristics, treatment and prognosis, etc. ResultsThe clinical features of AIDS patients combined with PCP included cough, dyspnea and fever, without obvious positive signs in the lung.The patients were divided as a mild group, a moderate group and a severe group according to the levels of PaO2.There was significant difference among three groups in serum albumin level [(23±3) g/L vs. (30±5) g/L and (28±6) g/L, P < 0.01].There were no significant differences among three groups in CD4+ T lymphocyte and lactate dehydrogenase (LDH) (P > 0.05).The typical chest radiograph feature of HRCT was ground-glass shadows in both lungs, and may be associated with reticular shadows or "gravel sign" and cyst.Of 50 patients, 16 patients were diagnosed via pathology of transbronchial lung biopsy(TBLB) and only 5 patients were diagnosed via silver staining of the bronchoalveolar lavage fluid (BALF).The other patients were clinically diagnosed.100% of the patients were treated with sulfamethoxazole (SMZco), 64%with caspofungin, and 72% with glucocorticoid.All the patients relieved with no death in hospital. ConclusionWhen a patient got cough, dyspnea and fever, especially ground glass on HRCT in both lungs, AIDS combined with PCP should be highly considered, and diagnostic treatment with SMZco and CD4+ T lymphocyte measurement should be conducted as soon as possible, so as to reduce misdiagnosis and mortality.
Objective To assess the effect of early antiretroviral therapy on acquired immune deficiency syndrome in Butuo County, Liangshan Autonomous Prefecture. Methods A total of 1 037 patients who underwent antiretroviral therapy between January 1st 2012 and December 31st 2013 in Butuo Coungty were divided into 2 groups. The early treatment group (with CD4+ lymphocyte count >350 /mm3) was group A (n=459) and delayed treatment group (with CD4+ lymphocyte count≤350 /mm3) was group B. After 18-month treatment, the treatment retention rate, clinical effect and the side effects of medication in two groups were observed and analyzed. Results After 18 months, there were 297 (64.7%) and 320 (55.4%) patients who were persisting in treatment in group A and B, respectively; while the mortality was 6.1% (28/459) and 14.4% (83/578), respectively in group A and B. The differences were significant (P<0.001). The rate of virological suppression in group A and B was 64.0% (190/297) and 63.8% (204/320) respectively without any significant difference (P>0.05). Compared with baseline CD4+ T lymphocyte counts, the growth rate of CD4+ T lymphocyte count in group A and B was 5.7% and 37.5%, respectively; the difference was significant (P<0.001) Conclusions Early treatment for acquired immune deficiency syndrome in Butuo County, Liangshan Autonomous Prefecture is effective, however, its growth rate of CD4+ T lymphocyte count is lower than that of delayed treatment. Early treatment doesn’t cause the increasement of the risk of common adverse reactions of medication, and it can reduce the mortality.
ObjectivesTo evaluate the effects of short message service (SMS) intervention for improving antiretroviral treatment adherence in HIV patients by meta-analysis.MethodsDatabases including PubMed, EMbase, CINAHL, Web of Science, ScienceDirect, The Cochrane Library, CNKI, WanFang Data, VIP and CBM were searched electronically from January 2000 to December 2018 to collect randomized controlled trials (RCTs) on the efficacy of SMS intervention on HIV patients. Two reviewers independently screened literature, extracted data, and assessed risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software.ResultsA total of 10 RCTs with 2 411 patients were included. The meta-analysis showed that SMS intervention could improve significantly treatment adherence of HIV patients (RR=1.11, 95%CI 1.03 to 1.20, P<0.01). The subgroup analysis showed that weekly texting had an effect on treatment adherence (RR=1.15, 95%CI 1.00 to 1.33, P<0.05); personal sending (RR=1.17, 95%CI 0.99 to 1.38, P=0.06) and daily sending (RR=1.02, 95%CI 0.83 to 1.26, P=0.84) of SMS had no statistical significance on treatment adherence; the intervention duration of 6 months (RR=1.11, 95%CI 1.00 to 1.23, P=0.05) could improve the treatment adherence, while the intervention duration of 12 months (RR=1.07, 95%CI 0.98 to 1.17, P=0.13) had no statistical difference on treatment adherence; there was no statistical difference in CD4+ cell count before and after treatment (WMD=4.18, 95%CI −39.33 to 47.69, P=0.85).ConclusionsBy comparing SMS intervention with routine nursing, sending SMS weekly for 6 months to remind HIV patients to take medicine can improve treatment adherence. Due to the limitation of quantity and quality of the included studies, the above conclusions are required to be assessed by more high-quality studies.
Zhaojue is a deeply impoverished county located in Liangshan Autonomous Prefecture with high prevalence of human immunodeficiency virus infection. Based on local conditions, West China Hospital of Sichuan University has established a targeted supporting mode called “three-level organization and five-in-one”. This mode integrates administrative support teams, multiple disciplinary technical support teams and on-site expert teams to achieve five goals, including building effective teams, promoting clinical practice, enhancing skill training, focusing on academics and building a systematic platform. This model has improved the ability of treatment on human immunodeficiency virus infection and overall health services in Zhaojue County. It also reflects the responsibility of West China Hospital of Sichuan University in poverty alleviation and public welfare.
Objective To investigate the AIDS knowledge and sexual behavior of middle school students in the key areas of HIV/AIDS epidemic in Liangshan, Sichuan Province in 2015 and 2020, so as to understand the epidemic trend and acquire possible references for future prevention. Methods A survey on AIDS knowledge and sexual behavior of middle school students was conducted in 2015 and 2020 in the key areas of HIV/AIDS epidemic in Liangshan, Sichuan Province, respectively. The prevalences of HIV/AIDS knowledge and sexual behavior were analyzed. Results The rate of AIDS education was increasing, which was 75.4% in 2015 and 89.3% in 2020, respectively. However, the awareness rate of AIDS remained low, which was 44.4% in 2015 and 53.3% in 2020, respectively. The reported rate of sexual behavior decreased, which was 12.8% in 2015 and 1.6% in 2020, respectively. The condom usage rates were still low, with 47.4% and 55.8%, respectively in 2015 and 2020. Conclusions The AIDS publicity and education work in Liangshan is effective, and the awareness rate of AIDS, the rate of sexual behavior and the usage rate of condom are improving well. However, the slow increase in the awareness rate of AIDS and the usage rate of condom require further in-depth analysis aiming at the specification of this area so that effective scientific measures can be carried out to prevent the HIV/AIDS diffusion.
