Clinical features of fundus lesions of 74 patients with acquired immunodeficiency syndrome in Shenyang / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the clinical features and factors of fundus lesions in patients with acquired immunodeficiency syndrome(AIDS)in Shenyang and the relationship between fundus lesions and CD4+T cell count.METHODS: Retrospective case study. A total of 74 cases with AIDS who were treated in the Central Hospital of Liaoning Electric Power Supply Co., Ltd., from January 2021 to December 2021 were selected. The fundus manifestation and CD4+T cell count of the patients were analyzed.RESULTS: The total detection rate of fundus lesions in AIDS patients was 58%. CD4+T cell count in the patients with fundus lesions was significantly lower than that in the patients with normal fundus [29(6, 55)/μL vs. 76(35, 103)/μL, P<0.01]. The rate of fundus lesions was the highest in the patients with CD4+T cell count ≤ 50/μL(74%). Logistic regression analysis showed that as the CD4+T cell count increased, the incidence of fundus lesions decreased(OR=0.977, 95%CI 0.964～0.991, P<0.01).CONCLUSION: Fundus lesions in AIDS patients related to CD4+T cell count. Decreasing CD4+T cell count was a risk factor of fundus lesions for AIDS patients. Routine fundus examination is important for the early diagnosis of fundus lesions in AIDS patients.

Viral selection pressure and CD4+T cell epitope in HLA-DRB1 * 11:01 of HCV infected patients / 中国输血杂志

【Objective】 HLA-DRB1 * 11:01, as a class HLA-Ⅱ gene, was reported to be associated with spontaneous clearance of HCV in Han and Li population. Our study was to investigate the effects of viral selection pressure and CD4+T cell epitope on the natural outcome of HCV infection in HLA-DRB1 * 11:01 positive infected patients. 【Methods】 The positive selection sites and population growth of E1E2 and NS3 genes of common HCV 6a in HLA-DRB1 * 11:01 positive and negative groups in Guangdong were respectively analyzed. The peptide library covering the conserved regions of common HCV genotypes was used to stimulate HCV spontaneous clearance group and chronic infection group using ELISPOT method. Reactive peptides were obtained according to the number of spot-forming cells per well and the frequency of occurrence in different groups. 【Results】 The positive selection sites (PSSs) of E1E2 and NS3 of common HCV 6a in HLA-DRB1 * 11:01 negative group were greater than those in HLA-DRB1 * 11:01 positive group. Furthermore, the number of PPSs in CD4+T cell peptide in HLA-DRB1 * 11:01 negative group were also greater than those in HLA-DRB1 * 11:01 positive group; Both groups of HCV 6a had a population growth in Guangdong, and the expansion trend of HLA-DRB1 * 11:01 negative group was significantly higher than that of HLA-DRB1 * 11 :01 positive group. Compared to HCV chronic infection group, the response rate of HCV spontaneous clearance group to five peptides (C-52 E2691-707, C-119 NS31545-1560, C-134 NS4A1669-1684, C-154 NS4B1912-1927, C-159 NS4B1929-1944) was higher. However, the HCV chronic infection group showed a higher response rate to two of the peptides(C-111 NS31497-1512, C-130 NS31650-1665). When HLA-DRB1 * 11:01 typing was considered, there was no significant difference in HCV-specific immune response generated by PBMCs between HLA-DRB1 * 11:01 positive and HLA-DRB1 * 11:01 negative groups. 【Conclusion】 This study revealed the relationship between viral selection pressure of HLA-DRB1 * 11:01 HCV infected persons and CD4+T cell antigen epitopes. At the same time, CD4+ T cell antigen epitopes of HCV pan-genotype were obtained, providing basic data for the development of T cell vaccine suitable for HCV pan-genotype.

Characteristics and the first CD4+T lymphocyte counts of newly reported HIV-infected cases aged 50 and above in Dehong Prefecture of Yunnan Province during 2016 to 2021 / 上海预防医学

ObjectiveTo investigate the factors that influence the first CD4+T lymphocyte counts in newly reported HIV-infected cases aged 50 and above in Dehong Prefecture of Yunnan Province during 2016 to 2021， and to understand the patient immune status and disease progression so as to provide scientific basis for HIV prevention and control strategies in the future. MethodsData was collected from the national HIV/AIDS information system. Multivariate logistic regression was used for the analysis of factors affecting the first CD4+T lymphocyte counts. ResultsA total of 642 cases of HIV infection were newly reported， among them， 571 cases had CD4+T lymphocyte counts and 200 cases （35.03%） had CD4+T lymphocyte counts <200 cells·μL-1. Patients who were in the 50-59 age group， male， divorced or widowed， and less educated were more likely to have CD4+T lymphocyte counts <200 cells·μL-1. Compared with active testing consultants， forced reeducation through labor or drug rehabilitation cases were less likely to have CD4+T lymphocyte counts <200 cells·μL-1. ConclusionThere is no obvious upward trend in newly reported HIV infected persons aged 50 years and above in Dehong Prefecture during 2016 to 2021. However， the situation of CD4+T lymphocyte counts <200 cells·μL-1 is still serious. Attention should be paid to the key groups： male， Chinese nationality， farmers， Han nationality， married or divorced， junior high school education or below， and heterosexual transmission. It is necessary to strengthen the intervention in people aged 50 and above and improve the detection efficiency.

Value of dynamic monitoring of absolute value and function of peripheral blood lymphocyte subsets in predicting the risk of early viral infection after kidney transplantation / 器官移植

Objective To investigate the predictive and diagnostic value of absolute value and function of different lymphocyte subsets in evaluating the risk of early viral infection after kidney transplantation. Methods Ninety-five kidney transplant recipients were enrolled in this prospective observational cohort study, and divided into the stable group (n=77) and infection group (n=18) according to postoperative immune status. Peripheral blood samples were collected for flow cytometry before operation, and 2 weeks, 1 month, 2 months and 6 months after operation. The dynamic changes of the absolute values of CD4+T cells, CD8+T cells and natural killer (NK) cells were compared between two groups. The function of lymphocyte subsets in two groups was evaluated by detecting the proportion of interferon (IFN)-γ+CD4+T cells, IFN-γ+CD8+T cells and IFN-γ+NK cells. The value of the absolute values and function of lymphocyte subsets in predicting and diagnosing viral infection in the early stage after kidney transplantation was evaluated. Results During viral infection, the absolute values of CD4+T cells, CD8+T cells and NK cells in the infection group were at a relatively low level. At 2 months after operation, the absolute values of CD4+T cells and NK cells in the infection group were lower than those in the stable group. At 6 months after operation, the absolute values of CD4+T cells and CD8+T cells in the infection group were significantly lower compared with those in the stable group (all P < 0.05). During viral infection, the proportion of IFN-γ+CD4+T cells, IFN-γ+CD8+T cells and IFN-γ+NK cells in the infection group were all at a relatively low level, especially that of IFN-γ+CD8+T cells decreased most significantly. At postoperative 2 months, the proportion of IFN-γ+CD8+T cells and IFN-γ+NK cells in the infection group was significantly higher than those in the stable group. At 6 months after operation, the proportion of IFN-γ+CD4+T cells and IFN-γ+CD8+T cells in the infection group was significantly higher than those in the stable group (all P < 0.05). Logistic regression analysis showed that the increasing proportion of IFN-γ+CD8+T cells and IFN-γ+NK cells was correlated with the increasing risk of viral infection at 2 months after operation (both P < 0.05). The receiver operating characteristic (ROC) curve demonstrated that the diagnostic value of absolute values of lymphocyte subsets combined with IFN-γ secretion function for viral infection in the immunocompromised recipients was significantly higher than that of absolute values of lymphocyte subsets alone (P < 0.05). Conclusions Dynamic monitoring of the changes of absolute values and function of lymphocyte subsets provides critical reference value for the prediction, diagnosis and medication guidance of viral infection.

Analysis of late detection of HIV/AIDS cases aged 50 years and above in Jilin Province / 上海预防医学

ObjectiveTo investigate the late detection of HIV/AIDS cases in the elderly in Jilin Province and analyze its influencing factors， to provide theoretical basis for improving their life quality. MethodsThe first CD4 values of HIV/AIDS patients aged 50 years and above living in Jilin Province were used to estimate late detection， and the influencing factors of late detection in elderly cases were analyzed. ResultsThe average CD4 cell count of newly reported HIV/AIDS cases aged 50 and above in Jilin Province from 1996 to 2021 was （230.55±191.97）， the low value group accounted for the largest proportion （50.8%）， and the late detection rate was 59.3% （1397/2325）. The late detection cases were mainly from sexual transmission （46.8% for same-sex and 48.2% for heterosexual contact）. From the perspective of sample sources， most of the late detection patients were diagnosed while testing for other illnesses， followed by testing and consulting. In terms of contact history， the late detection of cases of men who have sex with men was higher. The binary logistic regression analysis showed that gender， marriage， sample source and report year were the factors affecting the late detection of AIDS. The late detection rate of males was higher， and cases of married couples were more likely to be late detection. With the increase of report year， the late detection rate decreased， and testing and counseling could effectively reduce the late detection rate of AIDS. ConclusionThe CD4 cell count in the first detection of HIV/AIDS in the elderly in Jilin Province is low， and the late detection rate of male cases is high. In recent years， the expansion of voluntary counseling and testing in Jilin Province has effectively reduced the late detection rate of HIV/AIDS. At the same time， sex education should be strengthened for the elderly， healthy marital relationships should be advocated and more attention should be paid to the mental health of the elderly.

Preliminary identification of CD4 T cell epitopes in genotype 1 and 6 of hepatitis C virus / 中国输血杂志

【Objective】 To study the CD4 T cell epitopes in Core and NS3 protein of genotype 1(GT1) and 6(GT6) of hepatitis C virus(HCV). 【Methods】 A total of 298 overlapping peptides(16-mer) spanning Core and NS3 protein of GT1 and GT6 HCV were synthesized. Peripheral blood mononuclear cells(PBMCs) from 17 HCV+ and 7 healthy blood donors were stimulated by peptide pools, followed by evaluating T cell response by IFN-γ ELISPOT, by which 21 peptides with positive results were found. These peptides were further applied to individually stimulate 20 HCV+ and 18 healthy PBMCs. The differences of responsive frequencies to the 21 positive peptides between the two study groups were compared. 【Results】 Pooled and individual peptide stimulation tests showed that HCV+ PBMCs were responsive to the stimulation of 5 peptides(GT1 NS31273-1288 and NS31315-1330; GT6 NS31033-1048, NS31087-1102 and NS31351-1366), with a responsive frequency ranging 18.9%-27.0%. In contrast, healthy PBMCs were not or low responsive(0%-4.0%) to these five peptides. The responsive frequencies were statistically different between the two groups(P<0.05). No reported epitopes in IEDB were found identical with these 5 peptides via sequence alignment. 【Conclusion】 Our study identified novel CD4 T cell epitopes in NS3 protein of GT1 and GT6 HCV, which has potential application value for the research and development of HCV vaccine.

The changes and influencing factors of CD4+ T cell numbers during different periods of antiviral therapy in HIV/AIDS patients in Yichang City / 公共卫生与预防医学

Objective To analyze the changes of CD4+ T cell numbers at different periods of antiviral therapy in HIV-infected and AIDS patients (HIV/AIDS) in Yichang City. Methods The relevant information was retrieved from the National AIDS Comprehensive Prevention Information System-Antiretroviral Treatment Management Database. Changes in the number of CD4+ T cells were analyzed in HIV/AIDS patients who started receiving highly active antiretroviral therapy (HAART) and continued the treatment for 3 years from January 1, 2003 to December 31, 2017 in Yichang. Results The number of CD4+T lymphocytes in 550 HIV/AIDS cases increased significantly at various time points within 3 years after treatment, and increased with the increase of treatment time（F=100.20，P<0.001）. The CD4+T cell counts of different baseline level groups were statistically different before and after treatment（F=8.57，P<0.01）. The CD4+ T cell counts of patients who started treatment at age of 15-30 years old increased faster than those who started treatment at age of over 30 years old（F=1.27，P<0.05）. Conclusion HAART has a significant effect on the increase of CD4+T cells, and the early treatment is more effective. Early detection, diagnosis and treatment should be promoted, and anti-viral treatment should be actively carried out.

Prevalence and Types of Mucocutaneous Disorders, Their Correlation to CD4 Count and Their Impact on Quality of Life in Adults with HIV Infection

Background@#Data on prevalence and type of mucocutaneous diseases in HIV-positive patients and their impact on quality of life (QoL) are sparse. We aim to determine prevalence and type of mucocutaneous disorders, their correlation to CD4+ counts and impact on QoL for adults with HIV, using the Dermatology Life Quality Index (DLQI).@*Methods@#A cross-sectional study of HIV-infected adults seen in HIV and Dermatology Clinic.@*Results@#The majority (90%) of 174 participants recruited was male. Median age at diagnosis of HIV infection was 29 years (IQR 10). Mucocutaneous disorders were present in 90.2%, out of which 58.6% had two or more mucocutaneous disorders. Mean CD4+ count was significantly lower in patients with, compared to those without mucocutaneous disorders (363 vs 548 cells/µL; p=0.030). Infections accounted for 67.2% of all mucocutaneous disorders seen, followed by inflammatory dermatoses (51.7%), cutaneous adverse drug reactions (17.8%) and neoplasm (2.3%). The five most frequent manifestations were eczema (22.4%), anogenital warts (21.2%), candidiasis (16.7%), dermatophytosis (15.5%) and secondary syphilis (12.0%). Oral candidiasis, pruritic papular eruption, drug-induced maculopapular eruption and drug rash with eosinophilia and systemic symptoms were significantly more prevalent in patients with CD4+ counts <200 cells/µL but anogenital warts were more prevalent in patients with CD4+ counts ≥200 cells/µL. The mean DLQI score was 8.39 (SD ± 6.83). QoL was severely impaired (DLQI >10) in 34.4%.@*Conclusion@#Mucocutaneous disorders were common in HIV patients causing significant impairment in quality of life. Prevalence co-related with low CD4+ counts. Adequate management of HIV may reduce the prevalence of mucocutaneous disorders and improve QoL.

Relationship between lncRNA and the differentiation of CD4+ T lymphocyte subsets in autoimmune diseases / 药学学报

Long non-coding RNA (lncRNA) has a wide range of biological functions in epigenetic, cell cycle, cell differentiation and other life activities, and that affect the development and differentiation of immune cells and the maintenance of homeostasis in the immune system. CD4+ T cell subsets are heterogeneous cells with different functions, including promoting the proliferation and differentiation of T cells, B cells and other immune cells, and coordinating related functions between immune cells. Autoimmune disease (AID) is a chronic inflammatory disease caused by an autoantigen immune reaction. lncRNA and CD4+ T cell subsets are involved in the occurrence and progression of the disease. This article reviews the relationship between lncRNA and the differentiation of AID CD4+ T cell subsets.

Aspectos clínicos y de laboratorio en pacientes con diagnóstico tardío de SIDA / Clinical and laboratory findings in patients with late diagnosis of AIDS

RESUMEN Introducción: El retraso diagnóstico de la infección por SIDA constituye un problema de gran magnitud con importantes repercusiones para los propios infectados y para la sociedad en general. Objetivos: Caracterizar a los pacientes con diagnóstico tardío de infección por VIH y su evolución a los 6 meses del diagnóstico. Material y Métodos: Se realizó un estudio longitudinal de corte prospectivo que incluyó 248 casos con diagnóstico positivo de infección por VIH durante su ingreso o en la consulta de infectología del Instituto de Medicina Tropical "Pedro Kourí" desde enero de 2015 hasta diciembre de 2016, los que se dividieron en dos grupos de comparación, según diagnóstico tardío (n=79) o no (n=169) de la enfermedad. Resultados: La edad avanzada y el sexo masculino fueron factores relacionados con el diagnóstico tardío de la infección por VIH. La fiebre (31,7%) y los síntomas respiratorios (20,3%) fueron las formas más frecuentes de presentación, mientras que la neumonía por Pneumocystis jirovecii fue la enfermedad con más incidencia en el momento del diagnóstico. La mitad de los pacientes se encontraban con inmunodepresión severa en el momento del diagnóstico. Los pacientes con diagnóstico tardío mostraron una supervivencia significativamente menor a los 6 meses del diagnóstico en comparación con los pacientes con diagnóstico precoz. La carga viral y el nivel de linfocitos CD4 fueron parámetros de laboratorio con un alto valor predictivo de mortalidad. Conclusiones: El diagnóstico tardío de infección por VIH conlleva un alto riesgo de mortalidad, mayor en aquellos con afectación de la carga viral y el nivel de linfocitos T CD4+.

ABSTRACT Introduction: Late diagnosis of HIV is a major problem with important consequences for the people infected with this virus and the society in general. Objectives: To characterize patients with late diagnosis of HIV infection and their evolution six months after diagnosis. Material and Methods: We conducted a prospective longitudinal study which included 248 cases with positive diagnosis of HIV infection during admission at the Pedro Kourí Tropical Medicine Institute between January 2015 and December 2016. They were divided into two comparison groups which included patients with late diagnosis (n=79) and those with no late diagnosis (n=169) of the disease. Results: Advanced age and male sex were factors related to the late diagnosis of HIV infection. Fever (31.7%) and respiratory symptoms (20.3%) were the most frequent forms of presentation, whereas Pneumocystis jirovecii pneumonia was the disease with the highest incidence at the time of diagnosis. Half of the patients were found to have severe immunosuppression at the time of diagnosis. Patients with late diagnosis showed a significantly diminished survival six months after being diagnosed compared with those patients with early diagnosis. Viral load and CD4+ T count were laboratory parameters with a high predictive value of mortality. Conclusions: Late diagnosis of HIV leads to a high risk of mortality, which is higher in those with affectation of the viral load and low CD4+ T cell count.

Characteristics of treatment-naïve HBV-infected individuals with HIV-1 coinfection: A cross-sectional study from South India

Purpose: Human immunodeficiency virus-1 (HIV-1) and hepatitis B virus (HBV) coinfection has become a major health problem across the globe. The increased life expectancy of HIV-1 patients due to antiretroviral therapy has led to the emergence of liver disease as a major mortality factor among them. The purpose of the study was to examine the baseline characteristics of HBV in treatment-naïve HBV/HIV coinfection from southern India compared to monoinfected individuals. Materials and Methods: The study was cross sectional in design, and samples were examined from 80 HIV-1, 70 HBV and 35 HBV/HIV-coinfected individuals using chemiluminescent microparticle immunoassay, real-time polymerase chain reaction and flow cytometry assays. Results: There was a significant increase in HBV DNA (P = 0.0001), higher hepatitis B e antigen percentage difference (P = 0.027) and lower CD4 counts (P = 0.01) among the HBV/HIV-coinfected individuals, but no difference in the HIV-1 viral load compared to HIV-1-monoinfected individuals. Also, the aspartate aminotransferase levels, prothrombin time and the international normalised ratio were significantly high among coinfected individuals. Conclusion: These findings conclude that HIV-1 coinfection can have serious implications on the outcome of HBV-related liver disease. To the contrary, HBV infection had no consequence on the progression of HIV-1 disease but distinctly lowered CD4+ T-cells.

Circulating Low Absolute CD4⁺ T Cell Counts May Predict Poor Prognosis in Extranodal NK/T-Cell Lymphoma Patients Treating with Pegaspargase-Based Chemotherapy / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: Extranodal natural killer/T-cell lymphoma, nasal type (ENKTL) is a rare subtype of non-Hodgkin lymphoma, and asparaginase-based regimens are the best first-line treatments. Data on the role of specific circulating lymphocyte subsets in the progression of ENKTL are limited. The aim of this study was to investigate the clinical correlation and distribution of circulating absolute CD4+ T-cell counts (ACD4Cs) in ENKTL. MATERIALS AND METHODS: We retrospectively searched medical records for 70 newly diagnosed ENKTL patients treated with pegaspargase-based regimens. Comparison of ACD4Cs as a continuous parameter in different groups was calculated. Univariate and multivariate analyses were used to assess prognostic factors for overall survival (OS) and progression-free survival (PFS). RESULTS: Stage III/IV, B symptoms, elevated lactate dehydrogenase, monocytopenia, high-intermediate and high risk International Prognostic Index (IPI) and Korean Prognostic Index (KPI), high risk Prognostic Index of Natural Killer Lymphoma (PINK), and lower lymphocytes were significantly associated with low ACD4C at diagnosis. With a median follow-up time of 32 months, patients who had an ACD4C < 0.30×109/L had a worse OS. Median OS was 11 months and median PFS was 5 months in the low ACD4C cohort. There were significant differences in both OS and PFS between the two cohorts. Moreover, multivariate Cox analysis identified ACD4Cs as an independent predictor for OS and PFS. CONCLUSION: Low ACD4Cs were associated with poorer survival and could act as a negative predictor for ENKTL patients treated with asparaginase-based regimens.

Primary study on the effect of glucose on mouse CD4+ T cell differentiation and its mechanism / 上海交通大学学报（医学版）

Objective :To study the effect of glucose on mouse CD4+ T cell differentiation. Methods :Mouse naïve CD4+ T cells cultured in the regulatory T cell (Treg), Th1, Th17 or Th2 differention condition were treated with different concentrations of glucose for 5 days. Treg, Th1, Th17 or Th2 percentages were measured by flow cytometry. Quantitative real-time PCR was used to detect the gene expressions of related cytokines and transcriptional factors. Results :The proportions of Treg and Th2 as well as the gene expressions of transforming growth factor-β, interleukin-4 (IL-4) and IL-13, and transcriptional factors, Foxp3 (forkhead box P3) and Gata3 (GATA binding protein 3), were increased significantly with the treatment of increasing concentration of glucose. On the contrary, with the glucose treatment, the percentages of Th1 and Th17 were reduced, and the gene expressions of the related cytokines and cytokine receptors, such as interferon-γ, IL-17A, IL-17F, IL-22 and IL-23R, and the related transcriptional factors, Tbx21 (T-box transcription factor 21) and RORC (RAR related orphan receptor C), were decreased consistently. Conclusion :Glucose promotes Treg and Th2 differentiation while inhibits Th1 and Th17 differentiation in vitro.

Objective To investigate the cell origin of interleukin (IL)-22-secreting cell of mice infected with Trichinella spiralis (T.spiralis) at the early encapsulated stage.Methods Twelve Balb/c mice were divided into the infected group and the control group according to body weight by random number table.The infected mice were intragastrically administrated with 300 muscle larvae of T.spiralis,and the control mice were given the same amount of normal saline.The IL-22-secreting cell subsets in mouse splenic lymphocytes were detected by flow cytometry at the fourth week after infection.Results The proportion of IL-22-secreting cells in splenic lymphocytes of T.spiralis infected mice was increased when compared with control group [(0.88 ± 0.25)％ vs (0.28 ±0.17)％,t =-4.899,P ＜ 0.05].There was no significant difference between the proportion of CD3+IL-22+ cells and CD3-IL-22+ cells in the splenic lymphocytes of the infected group [(0.29 ± 0.17)％ vs (0.51 ± 0.17)％,t =-2.195,P ＞ 0.05],and the percentage of CD3-IL-22+ cells were similar between the infected group and the control group [(0.51 ± 0.17)％ vs (0.44 ± 0.22)％,t =-0.600,P ＞ 0.05].The proportion of CD3+IL-22+ cells in the infected group was significantly higher than that in the control group [(0.29 ± 0.17)％ vs (0.07 ± 0.06)％,t =-3.068,P ＜ 0.05],and the percentage of CD4+IL-22+ T cells and γδTCR+IL-22+ T cells were obviously increased in CD3+ lymphocytes [(1.28 ± 0.54)％ vs (0.16 ± 0.07)％,(0.33 ± 0.22)％ vs (0.02 ± 0.00)％,t =-4.997,-3.342,P ＜ 0.05].Conclusions The proportion of IL-22-secreting splenic lymphocytes is increased in mice infected with T.spiralis at the early encapsulated stage.The rise is caused by increased numbers of IL-22-secreting CD3 + lymphocytes,especially CD4+ T cells and γδT cells.

Ocular manifestations in patients attending antiretroviral therapy centre at a tertiary care hospital in Himachal Pradesh, India

Background & objectives: Ocular manifestations in HIV/AIDS patients range from adnexal disorders to the posterior segment disease. This study was aimed to evaluate the ocular manifestations, including vision-threatening manifestations in HIV-positive patients attending an antiretroviral therapy centre (ART) of a tertiary care hospital in north India and its association with the CD4+ cell count. Methods: This cross-sectional study was conducted in the department of Ophthalmology in collaboration with the ART centre. An equal number of patients were selected from each year i.e., 30 patients each from those registered in the year 2010 till 2015. These patients were selected randomly from the register using systematic randomization. Hence, a total of 150 patients were examined for ocular manifestations. All the patients included in this study were on highly active ART. Results: Of the 150 patients examined, 53 per cent were females and 47 per cent were males. Heterosexual transmission was the most common mode of transmission in 126 (84%) patients. Maximum number of patients was in the age group of 31-40 yr. Ocular manifestations were present in 53 [35.3%; 95% confidence interval (CI): 28-43%] patients. Twelve (8%; 95% CI: 4-12%) patients had lid and adnexal manifestations. Anterior-segment manifestations were present in 20 (13.3%; 95% CI: 8-19%) patients. Posterior-segment manifestations were present in 21 (14%; 95% CI: 8-20%) and vision-threatening posterior-segment ocular lesions were present in 14 per cent of the patients. Univariate logistic regression showed a significant (P<0.001) inverse association of CD4+T-cell count with the vision-threatening posterior-segment ocular lesions. Interpretation & conclusions: Routine ocular examination may be done in all the HIV/AIDS patients to detect and treat vision-threatening ocular lesions at the earliest.

Effect of baseline CD4+ T cell count on drop-out of antiretroviral therapy in HIV infected persons in Guangxi Zhuang Autonomous Region, 2008-2015 / 中华流行病学杂志

Objective To investigate the effect of baseline CD4+T cell count (CD4) on drop-out of antiretroviral therapy (ART) in HIV infected persons.Methods Retrospective cohort was conducted in this study.HIV infected persons aged≥ 18 years and receiving free ART for the first time in Guangxi Zhuang Autonomous Region (Guangxi) from 2008 to 2015 were selected from the antiretroviral treatment database of National Comprehensive HIV/AIDS Information System,with follow-up conducted till May 30,2016.Cause-specific Cox proportional hazard models were used to evaluate effect of different CD4 on the drop-out of ART in the HIV infected persons.Results A total of 58 502 eligible study participants were included in this retrospective cohort study.The average drop-out ratio was 4.8/100 person-years.After controlling the following baseline covariates:age,sex,marital status,route of HIV infection,WHO clinical stage before ART,initial/current ART regiment,ART regiment adjustment,and year of initiating ART for potential confounding,the adjusted HR of drop-out for HIV infected persons with 200-cells/μl,351-cells/μl and ≥500 cells/μl were 1.110 (95％CI:1.053-1.171,P＜0.001),1.391 (95％CI:1.278-1.514,P＜0.001) and 1.695 (95％CI:1.497-1.918,P＜ 0.001),respectively,in risk for drop-out compared with those with baseline CD4 ＜200 cells/μ 1.Among the HIV infected persons,56.0％ (1 601/2 861) of drug withdrawal was due to poor compliance with medication.Conclusions With the increase of baseline CD4 when initiating ART,the risk for the drop-out in HIV infected persons increased significantly.To further reduce the drop-out of ART,it is important to take CD4 into account in initiating ART and to strengthen the health education on treatment compliancy and training for healthcare providers.

Programs on mobility, status of follow-up and CD4+T cell testing among people living with HIV/AIDS, in China 2011-2015 / 中华流行病学杂志

Objective To analyze the mobility,status of follow-up and CD4+T cell testing (CD4 testing) programs among people living with HIV (PLHIV) between 2011 and 2015 and to improve the prevention program on HIV secondary transmission.Methods Data were collected from both Case Reporting Cards and Follow-up Cards through the National HIV/AIDS Comprehensive Control and Prevention data system.Changes of residence among the newly reported cases and survival cases between 2011 and 2015 were analyzed by SPSS 24.0 software.Results The number of newly reported inter-provincial mobile PLHIV had been increasing,with proportions of the total reported cases from 10.0％ (5 576/55 805) in 2011 to 13.3 ％ (15 348/115 231) in 2015.After adjusting for related confounders,percentages of follow-up and CD4 testing were lower in inter-provincial and inter-prefectural mobile cases than those without.Conclusion Service regarding the follow-up and CD4 testing programs was affected by mobility of people living with HIV/AIDS.Programs on communication and personal contact should be strengthened in the follow-up management services for PLHIV.Information on potential mobility of PLH1V should be gathered timely by health workers during the subsequent follow-up period to avoid the loss of follow-up and CD4 testing on patients.

Initial follow-up and CD4+ T cell count test of newly reported students HIV cases in China, 2013-2017 / 中华预防医学杂志

Objective@#To analyze first follow-up and CD4+ T (CD4) cell count test of newly reported students HIV cases in China from 2013 to 2017.@*Methods@#Data were collected from both Case Reporting Cards and Follow-up Cards from China Information System for HIV/AIDS Control and Prevention between 1st January 2013 and 31st December 2017. The inclusion criteria are 15-24 years old students who were newly diagnosed with HIV infection. Logistic regression model was used to analyze relevant factors of the first CD4 test results less than 200 CD4 cells/μl.@*Results@#There were 12 037 newly diagnosed students HIV cases from 2013 to 2017. Most cases were male (97.7%), 19-22 years old (65.1%) and Han ethnicity (90.5%). At the time of diagnosis, the route of HIV infection was most frequently homosexual contact (82.2%). The majority of cases (46.9%) were diagnosed at HIV voluntary counseling and testing (VCT) location. About 2 465 (20.6%) students had unprotected intercourse in the past 3 months, of which 1 387 (56.8%) had 1 sexual partner, 610 (25.0%) with 2 sexual partners, 273 (11.2%) with 3 partners and 170 (7.0%) with more than 4 partners. 11.0% and 28.9% of cases had initial CD4 counts less than 200 cells/μl and 200-349 cells/μl. Compared to the male, younger than 18 years old and diagnosed at VCT location, female (OR=2.09, 95%CI: 1.51-2.89), aged 21 to 22 years (OR=1.25, 95%CI: 1.06-1.47), diagnosed in hospital settings (OR=2.20, 95%CI: 1.89-2.57) and preoperative testing (OR=1.36, 95%CI: 1.07-1.73) had greater proportion of the first CD4 test result less than 200 CD4 cells/μl.@*Conclusion@#The number of newly diagnosed students HIV cases significantly increased in past 5 years, and the proportion of late diagnosis was high. Female, aged 21 to 22 years, diagnosed in hospital settings and preoperative testing were related to the first CD4 test result less than 200 CD4 cells/μl.
