ABSTRACT
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.

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.

Objective@#To analyze the change trend of HIV genetic subtypes and compare the first CD4+T cell counts of newly diagnosed HIV infected patients in Liuzhou from 1998 to 2012, and provide a reference for AIDS prevention and control.@*Methods@#Newly diagnosed HIV-infected patients from 1998 to 2012 in Liuzhou were selected through national HIV/ADIS comprehensive response information management system. Their plasma samples were used for RNA gene extraction, amplification, sequencing and genotyping. Coharan-Armitage trend test was used to analyze the ratio trend of genetic subtypes and phylogenetic clusters of HIV and Wilcoxon Rank Sum Test was used to compare the first CD4+T cell counts (CD4) of the different subtype HIV infected patients.@*Results@#A total of 1 877 newly diagnosed HIV infected patients were included in the study. From 1998 to 2012, the proportions of CRF01_AE and CRF01_AE (Cluster 1) increased from 78.4% (76/97) to 91.5% (1 441/1 574), from 63.9% (62/97) to 74.0% (1 164/1 574), and the proportion of CRF07_BC decreased from 17.5% (17/97) to 4.6% (72/1 574), respectively (Z=4.632, P<0.001; Z=2.455, P=0.014; Z=-5.943, P<0.001). The median and interquartile range of the first CD4 of the patients infected with subtype CRF01_AE (Cluster 1), CRF01_AE (Cluster 2), CRF07_BC and CRF08_BC were 230 (83-375), 215 (48-351), 365 (254-503) and 334 (206-479) cell/μl, respectively. The first CD4 levels of the patients infected with subtype CRF01_AE (Cluster 1) or CRF01_AE (Cluster 2) were significantly lower than those of CRF07_BC (Z=-4.795, P<0.001; Z=-4.238, P<0.001).@*Conclusion@#The genetic subtypes of HIV were mainly CRF01_AE in newly diagnosed HIV-infected patients and this subtype proportion was in increase and the first CD4 levels of the patients were low in Liuzhou during 1998 to 2012.
ABSTRACT
Objective@#To explore drug resistance of different viral loads, and investigate the relationship between drug resistance and CD4+T cell counts in patients with HIV antiretroviral therapy (ART) in China from 2003 to 2015.@*Methods@#Data were extracted from the Chinese National HIVDR Surveillance database from 2003 to 2015. For this study, the data collected were as follows: having received ART for ≥12 months; 18 years or older; demographic characteristics, information of ART, CD4+T cell counts, viral load (VL) and HIV drug resistance of a total of 8 362 patients were collected. Multi-variables non-conditional logistic regression model was used to study the relationship between viral load, HIV drug resistance and CD4+T cell counts.@*Results@#Participants with age of (41.8±10.5) years were enrolled in this study. Among them, 59.9% (5 009 cases) were men. The percentage of CD4+T cell counts <200 cells/μl in the total population was 17.9% (1 496 cases), the highest was in VL ≥1 000 copies/ml with drug resistance, which was 43.0% (397/923) , followed by VL 50-999 copies/ml with drug resistance, which was 31.1% (69/222), and the lowest was in VL 50-999 copies/ml without drug resistance 13.2% (273/2 068). Compared to VL 50-999 copies/ml without drug resistance, VL<50 copies/ml, VL 50-999 with drug resistance, VL≥1 000 copies/ml without drug resistance, and VL ≥1 000 copies/ml with drug resistance, the OR (95%CI) of CD4 <200 cells/μl were 0.9 (0.7-1.0), 3.2 (2.3-4.4), 2.6 (2.1-3.2), and 4.9 (4.0-5.9), respectively. Among 222 patients with VL 50-999 and HIVDR, the most frequent antiretroviral drugs were EFV and NVP, both of which were NNRTI, and whose percentage both were 94.1% (209 cases). The most frequent mutations were M184V/I (NNRTI), and the percentage was 26.1% (58 cases). The second one was K103N (NNRTI), and the percentage was 22.5% (50 cases). The percentage of V32L/E (PI) and V82A (PI) were lower, they were 0.9% (2 cases) and 0.5% (1 case) respectively.@*Conclusion@#Decreased CD4+T cell counts were associated with HIV drug resistance at low viraemia. In the case of low viral load, the most vulnerable were the NNRTI antiviral drugs such as EFV and NVP.

ABSTRACT
Background: Usefulness of hemoglobin and albumin as prognostic markers for highly active anti-retroviral therapy for HIV-1 infection. Introduction: Anemia and hypoalbuminemia are common complications in human immunodeficiency virus (HIV) infection. We aimed to investigate the changes in hemoglobin and albumin levels in response to highly active antiretroviral therapy (HAART). Further, we evaluated the appropriateness of using hemoglobin and albumin as HIV disease progression markers. Materials and Methods: A prospective longitudinal study of 122 subjects was carried out. Pre-treatment, one year, and two year post-treatment hemoglobin, and albumin levels were correlated with respective CD4+ T cell counts. The sensitivity, specificity, and positive predictive value of each marker against CD4+ T cell counts were calculated in order to establish the appropriateness of use of these parameters as surrogate disease progression and prognostic markers. Results: Mean hemoglobin and albumin levels pre-, one, and two year post HAART were 9.7 g/dL, 12.1 g/dL, and 13.1 g/dL, respectively, P = 0.001; albumin: 3.7 gm%, 4.4 gm%, and 4.7 gm%, respectively, P = 0.001. There was a positive correlation between hemoglobin, albumin, and CD4+ T cell count at pre-treatment, one year, and two year post-treatment visit. Both albumin and hemoglobin had high sensitivity when compared to CD4+ T cell counts. Conclusions: Hemoglobin and albumin levels were found to increase after initiation of HAART. Hemoglobin and albumin were seen to be a strong prognostic marker of HIV disease progression at pre-, one, and two year post-treatment. Therefore, hemoglobin and albumin may be used together along with CD4 + T cell counts in HIV management, particularly in resource-poor settings.

Objective To explore the determinants and changes ofCD4+ T cell counts among antiretroviral treatnent-naive HIV/AIDS patients in Dchong prefecture, Yunnan province. Methods A retrospective cohort analysis was conducted on HIV-infected local residents, being reported during 1989 through May 2010, in Dehong prefecture. The patients had received at least two CD4 + T cell counting tests before receiving the antiretroviral treatment (ART). Difference between the first and the last CD4 + T cell counts was calculated and described. Logistic regression analysis was conducted to examine the determinants of significant depletion of CD4 + T cell counts among them. Results A total of 4487 HIV/AIDS patients were included in the study. The change of CD4 +T cell counts between the first and the last CD4 + T cell count tests had a median of-2.0 cells/μ l in month (IQR: -8.2-3.6) and was significantly associated with socio-demographic characteristics, HIV transmission mode,the first or baseline CD4+ T cell counts and the time interval between the first and the last CD4 + T cell counting tests etc. About 60.0％ (2693/4487) of the HIV/AIDS patients had deletions of CD4 + T cell counts, and 31.2％ (1400/4487) had significant ( ≥ 30％ ) deletions of CD4 + T cell counts. Results from the multiple logistic regression analysis indicated that age, ethnicity,marital status, HIV transmission mode, the first CD4+ T cell counts and the interval between the first and the last CD4+ T cell counting tests were significantly associated with the significant depletion of CD4 + T cell counts. Conclusion The changing rate of CD4 + T cell count among ART-naive local HIV-infected patients in Dehong prefecture, Yunnan province was relatively slow. However,substantial proportion of them showed significant decreases of CD4 + T cell counts, which was determined by many factors. More efforts were needed to systematically and consistently follow-up those HIV-infected patients and measure their CD4+ T cell counts in China, in order to instantaneously monitor the disease progression,and the initiation of ART, if necessary.
ABSTRACT
Antiretroviral therapy advances have proportioned to AIDS patients a survival increase. At the same time, the permanence of the seropositive people in the nosocomial environment becomes common not only by the adverse reactions caused by this therapy, but also by several opportunistic diseases that take them into and out of hospital environment. During the hospital permanence, the patients expose their impaired immune system to the nosocomial virulent microorganisms, and acquire destructive nosocomial infections that sometimes can be lethal. Among several hospital syndromes described, little is known about infections in immunocompromised patients and how their immune system is able to determine the course of the infection. The objective of this study was to describe the major microorganisms involved in the nosocomial infections of HIV-1 seropositive patients associated with their immunological status. The survey was carried out with the Hospital Infection Control Service records, from University Hospital, Londrina, Paraná, Southern of Brazil, during the period from July 2003 to July 2004. From all the cases studied (n=969), 24 patients (2.5%) had AIDS diagnosis and a half of them was women with the mean of CD4+ T cells counts of 158/mm³. The main topography of the infection was pulmonary (50.0%) and the main isolated microorganisms were Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. A major incidence of infection was observed in patients with CD4+ T cells counts lower than 50/mm³. The study of the relationship between the impairment of the immune system and infectious agents could provide a better healthcare of people living with HIV/AIDS and advances into the nosocomial infection control systems.
Avanços na terapia anti-retroviral têm proporcionado aos pacientes com AIDS um aumento na sobrevida. Ao mesmo tempo, a permanência de pacientes soropositivos no ambiente nosocomial torna-se comum não só pelos efeitos colaterais desta terapia, mas também pelas diversas doenças oportunistas que acometem estes indivíduos dentro e fora do ambiente hospitalar. Durante o período de internação, a fragilidade do sistema imunológico é exposta à virulência da microbiota nosocomial, adquirindo infecções hospitalares graves e muitas vezes fatais. Dentre as diversas síndromes de infecções hospitalares descritas, pouco se sabe sobre estas infecções em pacientes imunocomprometidos e sobre como o estado imunológico é capaz de determinar o curso destas infecções. Este trabalho teve como objetivo determinar os principais microrganismos envolvidos nas infecções hospitalares de pacientes soropositivos para a infecção pelo HIV-1 e descrever a associação com seu perfil imunológico. Realizou-se análise de dados de notificações do Serviço de Controle de Infecção Hospitalar do Hospital Universitário, Londrina, Paraná, na região sul do Brasil, no período de julho de 2003 a julho de 2004. Do total de casos estudados (n=969), 24 pacientes (2,5%) tinham o diagnóstico de AIDS, sendo metade do gênero feminino, com contagem média de células T CD4+ de 158,4/mm³. A principal topografia foi o sítio pulmonar (50,0%), sendo Staphylococcus aureus, Pseudomonas aeruginosa e Escherichia coli os principais microrganismos isolados. Observou-se maior incidência de infecção em pacientes com contagem de células T CD4+ menor que 50/mm³. O estudo da relação entre sistema imunológico e microrganismos causadores de infecções poderá contribuir para melhorias nos cuidados de pacientes com AIDS e avanços nos sistemas de controle de infecção hospitalar.
