In recent years, the incidence rate of ischemic stroke in people living with HIV/AIDS (PLWHA) is increasing, attracting wide attention from scholars at home and abroad. In addition to traditional risk factors of stroke, the secondary ischemic stroke in PLWHA is also affected by HIV infection. This study reviews the incidence rate and risk factors of secondary ischemic stroke in PLWHA, in order to provide a theoretical basis for preventing and reducing the incidence of ischemic stroke in PLWHA.
ObjectiveTo compare the value of CURB-65 score and expanded CURB-65 score in evaluating prognosis of pneumonia in non-HIV infected patient and HIV infected patient.MethodsThe study included 206 hospitalized pneumonia patients without HIV infection and 299 pneumonia patients with HIV infection. According to their clinical prognosis within 4 weeks of treatment, they were divided into a deterioration group and an improvement group. The basic situation and the differences of clinical indicators between the two groups were compared. The predictive value of CURB-65 score and expanded CURB-65 score for clinical prognosis of pneumonia in non-HIV infected patients and HIV infected patients was compared by using receiver operator characteristic (ROC) curve.ResultsFor the pneumonia patients without HIV infection, the area under ROC curve (AUC) of CURB-65 score and expanded CURB-65 score were 0.862 and 0.848, respectively. There was no significant difference in AUC between CURB-65 score and expanded CURB-65 score (Z=0.661, P=0.5084). The Youden indexes of CURB-65 score and expanded CURB-65 score were 60.11% and 54.92%, respectively. For the pneumonia patients with HIV infection, the AUC of CURB-65 score and expanded CURB-65 score were 0.588 and 0.634, respectively. There was no significant difference between them (Z=1.416, P=0.1567). The Youden index of the two scores was 19.53% and 20.52%, respectively.ConclusionsThe CURB-65 score and expanded CURB-65 score can effectively evaluate the clinical prognosis of pneumonia in non-HIV infected patients, but their predicted values are limited in evaluating the prognosis of pneumonia in HIV infected patients.
Objective To investigate the feasibility and methods of surgical treatment for HIV/AIDS patients with otolaryngology diseases. Methods From January 2016 to February 2017, nineteen patients with HIV/AIDS who underwent otolaryngology surgery were included in this study. The demographic data of patients, including age, gender, course of disease, CD4+ T lymphocyte count before operation and disease type were collected and the clinical treatment methods were summarized. The curative effect was analyzed retrospectively. Results The operations of all the 19 patients were successful without occupational exposure among medical staff. One patient with papillary squamous cell carcinoma did not received further treatment. The other 18 patients recovered well and their life quality was significantly improved. Conclusions If HIV/AIDS patients with otolaryngological diseases are examined preoperatively and have no surgical contraindications, the operation shloud be performed by controlling the surgical indications strictly. The life quality of the patients may be improved and the patients’ life may be prolonged after the surgery.
Objective To explore the operative safety of HIV-infected patients with colorectal cancer in different degrees of immunodeficiency. Methods A total of 56 patients, including 26 cases of HIV positive (HIV-positive group) and 28 cases of HIV negative (HIV-negative group), who underwent radical operation for colorectal cancer between January 2012 and December 2015, were enrolled in our study. We divided HIV-positive patients into three groups according to CD4+ T cells count in peripheral venous blood before 1 day (D0) of the surgery (HIV-positive Ⅰgroup with CD4+ T cells count >500/μL, HIV-positive Ⅱgroup with CD 4+ T cells count among 200–500/μL, and HIV-positive Ⅲ group with CD4+ T cells count <200/μL). Non-infective patients were enrolled in HIV-negative group. Leukocyte count, neutrophil percentage, lymphocyte percentage, CD 4+ T cells subsets count, and CD8+ T cells subsets count of the 4 groups in different time points were tested. In addition, we compared postoperative complications, carcinoembryonic antigen (CEA), and postoperative survival rate between the HIV-positive group and the HIV-negative group. Results In 56 cases, there were 26 cases of HIV-positive patients (including 10 cases of HIV-positive Ⅰ group, 8 cases of HIV-positive Ⅱ group and 10 cases of HIV-positive Ⅲ group). Variance results about repeated measurement data showed that, variation of leukocyte count, neutrophil percentage, lymphocyte percentage, and CD8+ T cells count among 4 groups after surgery had no statistical significance (P>0.05), in addition there was no significant on time effect and interactive effect of time and group (P>0.05). CD4+ T cells count in the 4 groups showed a trend from decline to rising with time going, and the time effect had statistical significance (P<0.05). The speed and amplitude of decline and recovery of CD4+ T cells count were different among groups, and the group effect had statistical significance (P<0.05). CEA showed a trend of decline after surgery in both HIV-positive group and HIV-negative group, and the time effect had statistical significance (P<0.05), but the group effect and interactive effect of time and group had no statistical significance (P>0.05). No statistically significant differences in amount of blood loss, duration of surgery, postoperative stay, nor complication rate (including incision infection, pulmonary infection, and opportunistic infections after surgery) were found between the HIV-positive group and the HIV-negative group (P>0.05). The overall survival situation of the HIV-positive group and the HIV-negative group had no statistical significance (P>0.05). Conclusions Radical operation for HIV-infected patients with colorectal cancer has an impact of " first inhibition and recovery” on cellular immunity over a period of time. Incidence of postoperative complications and survival rates are similar in HIV-positive patients and HIV-negative patients. In a word, it’s safe to have radical operation for colorectal cancer in HIV-positive patients under the proper perioperative treatment.
ObjectiveTo investigate the ultrasonic changes of liver during various immune periods with different number of CD4+ T lymphocytes in HIV/AIDS patients with chronic viral hepatitis. MethodsThe clinical data of 100 patients with chronic viral hepatitis diagnosed between January 2010 and December 2012 were selected. Among them, 50 simple chronic viral hepatitis patients were designated as the control group, and the other 50 HIV/AIDS patients with chronic viral hepatitis were regarded as the experimental group. Ultrasonographic observation was applied on patients of the experimental group according to different immune period based on the number of CD4+ T lymphocytes. Indexes observed included liver size, the edge of liver, capsule of liver and hepatic parenchymal echo. The cross-check analysis was employed between observed results and clinical laboratory results. ResultsAbnormal changes of the experimental group were shown on the ultrasound observation of liver in different CD4+ T lymphocyte count immune periods, including enlargement of the liver, slightly blunt liver margin, slightly thick capsule, dense and uniform, slightly rough and not so uniform, or rough and not uniform hepatic parenchymal echo. There was no significant difference in ultrasonic changes of liver between the two groups when the CD4+ T cell number was over 300/mm3. However, the difference was significant when the CD4+ T cell number was below 100/mm3. ConclusionLiver abnormalities become more obvious as CD4+ T cell count decreases in HIV/AIDS patients with chronic viral hepatitis. Comprehensive considerations of various liver ultrasound indicators are helpful in clinical evaluation of HIV/AIDS patients with chronic viral hepatitis.
【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.
Objective To analyze the clinical data of monkeypox (mpox) cases in Chengdu, to investigate the clinical characteristics of patients with mpox complicated with human immunodeficiency virus (HIV) / acquired immunodeficiency syndrome (AIDS), and provide reference for clinical diagnosis and treatment. Methods Mpox patients admitted to Public Health Clinical Center of Chengdu between June 29 and August 8, 2023 were continuously included. Patients were divided into an observation group and a control group based on whether they were complicated with HIV/AIDS. The clinical characteristics of two groups of patients were observed and compared. Results A total of 56 patients were included, all of whom were male; Age range from 19 to 51 years old, with an average of (31.6±5.9) years old; There were 23 cases in the observation group and 33 cases in the control group. Except for age, perianal lesions with infection, number of rashes, diarrhea, CD4+ lymphocyte count, CD4/CD8 ratio, syphilis, chest CT abnormalities, rash duration, and length of hospital stay (P<0.05), there was no statistically significant difference in epidemiological data, clinical features, auxiliary examinations, treatment, and intensive care unit admission between the two groups of patients (P>0.05). There was a statistically significant difference between the Ct values of throat swab nucleic acid and blister fluid nucleic acid in the total population [(30.1±4.4) vs. (23.4±3.8); t=5.462, P<0.001]. Conclusions Mpox patients complicated with HIV/AIDS are prone to persistent, diverse, and severe lesions due to relatively lower CD4+ lymphocyte counts. Therefore, it is necessary to actively provide symptomatic treatment and prevent complications for patients.
