Introduction: This study investigated the association of selected biopsychosocial factors (i.e., CD4 cell count, self-stigma, and social stigma) with the quality of life and adherence to treatment of people living with HIV in the National Capital Region. Methods: A cross-sectional study design was conducted to document the health status and behavior of respondents affiliated with a clinic in Quezon City. Participants answered an online questionnaire containing the Berger HIV Stigma Scale, WHO-QOL for HIV, and HIV Treatment Adherence SelfEfficacy Scale. Bivariate analyses and prevalence risk ratios were used to determine the association of selected biopsychosocial factors with quality of life and adherence to treatment. Results: One hundred respondents were analyzed, of which 42% had CD4 cell counts < 350 cells/mm3, 43% had high self-stigma and 36% had high social stigma while 11% had poor QOL and 7% had poor ATT. There was no significant association of CD4 cell count, self-stigma and social stigma with quality of life and with adherence to treatment. Conclusion A weak association was noted between poor QOL and low CD4 cell counts and among those who felt higher social stigma, but the relationships were not significant. The association between poor ATT and the selected biopsychosocial factors was not significant.

Background: With the recent rise in number of HIV/AIDS patients in the Philippines, knowledge of the most common mucosal and cutaneous findings among HIV/AIDS patients can be a valuable tool of assessment. Objectives: To determine the different mucosal and cutaneous disease findings of HIV/AIDS patients; evaluate their frequency and association with the latest CD4 cell counts, and to determine patients’ demographic and medical profiles. Methods: This is a cross-sectional study done at a tertiary hospital in Makati city from January 2017 to September 2018. Walk-in patients or those referred by Infectious Disease specialists were evaluated using a standardized history and physical examina- tion form. Latest CD4 counts were also obtained. Results: A total of 93 patients were enrolled. Majority were males (98%), with a mean age of 32 +/- 7.08, employed (64%), and on HAART (87%). A large part of the group (45%) has severe immunosuppression (CD4 counts <200/mm3). The most common manifes- tations were the following: non-infective, fungal, and drug-related dermatoses, with the most common dermatoses being seb- orrheic dermatitis, xerosis, pruritic papular eruptions (PPE), superficial fungal infections, drug hypersensitivity reactions, and syphilis. PPE was noted to be significantly associated with low CD4 counts. Conclusion Due to small population size, significant associations between the other dermatoses with their CD4 counts were not seen except for PPE, which was significantly associated with CD4 counts <200/mm3. Nevertheless, a strong suspicion for any underlying HIV//AIDS infection is still warranted in the presence of these dermatoses.

OBJECTIVE: To understand the differences in lymphocyte subsets in patients with different clinical classifications of corona virus disease 19 (COVID-19). METHODS: Eighty-one patients with COVID-19 who were admitted to the isolation ward under the responsibility of three medical aid teams in the Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, from February 8, 2020 to March 28, 2020, were selected to collect clinical data. According to the relevant diagnostic criteria, the disease status of the patients was classified into moderate cases (n=35), severe cases (n=39) and critical cases (n=7) when lymphocyte subset testing was performed. Their blood routine tests, lymphocyte subsets and other indicators were tested to compare whether there were differences in each indicator between the patients of different clinical classification groups. RESULTS: The differences in the absolute count of total lymphocytes, T-lymphocytes, CD4⁺T-lymphocytes, CD8⁺T-lymphocytes and natural killer (NK) cells among the three groups of patients were all statistically significant (P < 0.05), and the critical cases were significantly lower than the moderate and severe cases in the above indicators, and the indicators showed a decreasing trend with the severity of the disease. In 22 patients, the six indicators of the absolute count of T-lymphocytes, B-lymphocytes, CD4⁺T-lymphocytes, CD8⁺T-lymphocytes and NK cells, CD4⁺/CD8⁺ ratio were all within the normal reference range in the first test, and 59 patients had abnormalities of the above indicators, with the absolute count of NK cells and CD8⁺ T lymphocytes decreasing most frequently (61%, 56%). The patients with the absolute count of NK cells and CD8⁺ T lymphocytes below the normal reference range were one group, and the remaining abnormal patients were the other group. There were more critical cases in the former group (moderate : severe : critical cases were 4 : 8 : 7 vs. 19 : 21 : 0, respectively, P=0.001), and all the deaths were in this group (6 cases vs. 0 case, P=0.001). The absolute B lymphocyte count was below the normal reference range in 15 patients, and the remaining 64 cases were within the normal range. The ratio of moderate, severe and critical cases in the reduced group was 4 : 7 : 4, and the ratio of critical cases was more in normal group which was 30 : 31 : 3, and the difference between the two groups was statistically significant (P=0.043). CONCLUSION The more critical the clinical subtype of patients with COVID-19, the lower the absolute count of each subset of lymphocytes.

OBJECTIVE: To investigate the effects of different stimultors (PHA, PMA and IL-2) and culture systems (PBMC and whole blood) on the proliferation of human peripheral blood lymphocyte subsets, so as to provide the experimental basis for selecting the appropriate system according to the experimental purposes. METHODS: A total of 10 ml serum samples were collected from healthy volunteers (n=6). The 300 μl whole blood was directly used to detect lymphocyte subsets by flow cytometry. The 400 μl whole blood were inoculated respectively with 3 different stimulators at 37℃ and 5% CO2 for 60 h; Three different stimulators were also added to the PBMC which were isolated from 2 ml whole blood. Then the proliferation ability of lymphocyte subsets was analyzed by flow cytometry. RESULTS: After the PBMC were stimulated with PHA, CD4CD8CD3 lymphocytes were the most subset; The proportion of CD3CD4 T lymphocytes and CD3CD19 B lymphocytes decreased after being stimulated by PMA (P<0.01, P<0.05); the lymphocyte subset ratio had no significant change after being stimulated by IL-2. After the whole blood system was stimulated with PHA, the CD4/CD8 T lymphoblasts were main subsets, the counts of B lymphocytes and NK cells were reduced; after being stimulated with PMA, the number of CD8CD3 T lymphoblast and CD4CD8T lymphocytes increased, the B/NK cells were not distinguished with the surface markers; after the whole blood system was stimulated with IL-2, the proportion of NK cells significantly increased (P<0.05). CONCLUSION Lymphocyte proliferation stimulated by PMA is the fastest, while the effect of IL-2 on the lymphocyte subset proportion stimulated by IL-2 is the minimal. After being stimulated by PHA the division cycles of lymphocyte are the most.

OBJECTIVETo observe interventional effects of anti-viral therapy and Compound Qin-gre Granule (CQG) on host cellular immune functions of acute virus infection patients.

METHODSThirty acute virus infection patients were recruited to detect peripheral lymphocyte subsets. They were randomly assigned to two groups, the Western medicine treatment group (treated with anti-virus Western medicine) and the integrative medicine treatment group (treated with anti-virus Western medicine plus CQG). T-cell subsets were re-examined 7 days later. Changes between before and after treatment were observed. Effect on host cellular immune functions and efficacy were compared between the Western medicine treatment and the integrative medicine treatment.

RESULTSCompared with the normal control group, the percentage of peripheral T cells increased, and the percentage of B/NK cells decreased in acute virus infection patients (P < 0.01). Meanwhile, in T cell subsets, the percentage of CD8+ T cells and CD8+ CD38+ T cells increased (P < 0.05, P < 0.01); and percentages of CD4+ T cells, CD4+ CD28 + T cells, and CD8+ CD28+ T cells decreased (P < 0.05, P < 0.01). After one-week treatment, percentages of CD4+ T cells, CD4+ CD28+ T cells, and CD8+ CD28+ T cells increased (P < 0.05, P < 0.01), while the percentage of CD8+ CD38+ T cells decreased (P < 0.01). More significantly, these changes were greater in the integrative medicine treatment group than in the Western medicine treatment group (P < 0.05).

CONCLUSIONSDisarranged cellular immune functions existed in acute virus infection patients. CQG could significantly improve viral infection induced immunologic derangement and immunologic injury.

OBJECTIVE: To investigate the expression level of T lymphocyte subsets in elderly patients with newly diagnosed multiple myeloma (NDMM), and to evaluated the prognostic value of T lymphocytic abnormalities in elderly NDMM patients. METHODS: Pretreated peripheral blood of 39 newly diagnosed elder patients with MM was tested by multi-parameter flow cytometry (MFC) to quantitatively detect T lymphocyte subsets, including CD4T cell, CD8T cell, and CD4/CD8 ratio. The prognostic values T-lymphocyte subset were evaluated in newly diagnosed elderly patients with MM. RESULTS: The median follow-up time was 21.5 (range, 3.0-66.0) months. Absolute counts of CD4T cell and CD4/CD8 ratio positively correlated with prognosis. In the multivariate COX analysis, lower CD4/CD8 ratio and CD4T cell counts were identified to be independent adverse prognostic factors for OS. CONCLUSION Lower CD4/CD8 ratio and CD4T cell counts at initial diagnosis are independent unfavorable prognostic factors for elderly patients with MM, and T lymphocyte subsets are crucial indicators for MM patients' prognosis.
