CD4 T-Lymphocytes Count in HIV-<i>Toxoplasma gondii</i>Co-Infected Pregnant Women Undergoing a Prevention of Mother-to-Child Transmission Program

Toxoplasma gondii (T. gondii) is a parasite responsible of toxoplasmosis, a disease often asymptomatic but with serious consequences in pregnant women and immunocompromised subjects. Objective: This study aimed to investigate the impact of T. gondii infection on CD4+ T lymphocytes count in HIV-infected pregnant women. Methods: This was a cross-sectional study of pregnant women co-infected by HIV and T. gondii. The study was conducted from January to July 2016 at the Prevention of Mother-to-Child Transmission of HIV (PMTCT) sites in the Health District of Lacs in Togo. Diagnosis of HIV was performed by immuno-chromatographic methods with Determine TM HIV-1/2 and immuno-filtration with Tri-Dot HIV-1 and 2 kits. Presence of anti-toxoplasmic IgG and IgM antibodies was established via enzyme immunoassay using ELISA-BIOREX&reg;kit. Flow cytometry was used to count CD4+ T lymphocytes. Results: Our study found that of the 4599 pregnant women, 111 (2.41%) were HIV-positive. Among them, 109 (98.20%) were infected by HIV-1 and 2 (1.98%) by HIV-2. Antibodies against T. gondii were detected in 5.36% (IgM), 25% (IgG) and 3.57% (both IgM and IgG) of HIV 56 infected women. There was no significant difference between CD4 cell count in HIV (+)/T. gondii IgM (-)/IgG (-) infected pregnant women (378.8 ± 222.8 cell//μl) compared to HIV (+)/T. gondii/IgM (+) (457.3 ± 183.3 cell//μl), HIV (+)/T. gondii IgG (+) (419.4 ± 287.3 cell//μl) and HIV (+)/T. gondii IgM/IgG (+) (480.5 ± 252.4 cell/μl). Conclusion: This study showed that intracellular parasite T. gondii did not alter CD4+ T lymphocytes count in HIV/T. gondii co-infected pregnant women.

Poor CD4 count is a predictor of untreated depression in human immunodeficiency virus-positive African-Americans

AIM: To determine if efforts to improve antiretroviral therapy(ART) adherence minimizes the negative impact of depression on human immunodeficiency virus(HIV) outcomes. METHODS: A cross-sectional study of a clinic-based cohort of 158 HIV seropositive(HIV+) African Americans screened for major depressive disorder(MDD) in 2012. CD4 T lymphocyte(CD4+) counts were obtained from these individuals. Self-report on adherence to ART was determined from questionnaire administered during clinic visits. The primary outcome measure was conditional odds of having a poorer CD4+ count(< 350 cells/mm3). Association between CD4+ count and antidepressant-treated or untreated MDD subjects was examined controlling for self-reported adherence and other potential confounders. RESULTS: Out of 147 individuals with available CD4+ T lymphocyte data, 31% had CD4+ count < 350 cells/mm^3 and 28% reported poor ART adherence. As expected the group with > 350 cells/mm^3 CD4+ T lymphocyte endorsed significantly greater ART adherence compared to the group with < 350 cells/mm3 CD4+ T lymphocyte count(P < 0.004). Prevalence of MDD was 39.5% and 66% of individuals with MDD took antidepressants. Poor CD4+ T lymphocyte count was associated with poor ART adherence and MDD. Adjusting for ART adherence, age, sex and education, which were potential confounders, the association between MDD and poor CD4+ T lymphocyte remained significant only in the untreated MDD group.CONCLUSION: Therefore, CD4+ count could be a clinical marker of untreated depression in HIV+. Also, mental health care may be relevant to primary care of HIV+ patients.

Haematology Parameters of Apparently Healthy Prospective Whole Blood Donors in a Nigerian Hospital Setting

Background: Adequate selection of a prospective whole blood donor protects his health and safety of the recipient. Objectives: The main objective of this study was to determine the haematology parameters of apparently healthy prospective whole blood donors. Participants and Methods: This was a hospital based prospective study carried out from August to October 2020 at the blood transfusion unit of the Lagos State University Teaching Hospital (LASUTH), Ikeja, Nigeria. A structured pretested questionnaire was used for data collection. The socio demographic status and the haematology parameters of apparently healthy prospective whole blood donors who tested negative for HIV, hepatitis B and C markers were captured. Obtained data were analysed with the statistical package for the social scientist software version 20. Results: One hundred male (97.1%) and three female (2.9%) apparently healthy prospective whole blood donors were studied. The median age of study subjects was 30 years. Obtained median haematology parameter values were 13 g/dl, 40%, 4.9/nl and 203.9/nl for haemoglobin concentration, haematocrit, total white cell and platelet counts respectively. The median values for the mean corpuscular haemoglobin concentration (MCHC), mean corpuscular haemoglobin (MCH) and mean corpuscular volume (MCV) of participants were 32.6 g/dl, 27.7 pg and 85.7 fl respectively. Observed prevalence of subnormal haematology parameters for haemoglobin concentration, total white cells, platelets were 12.6%, 25.2%, and 13.6% respectively. Also subnormal values for MCHC, MCH, MCV were 11.7%, 26.2%, and 16.5% respectively among prospective whole blood donors in this study. No higher than normal haematology parameter values were observed. Median values for erythrocyte sedimentation rate was 8.4 mm/hr. Conclusion: A significant percentage of apparently healthy prospective whole blood donors had subnormal haematology parameters values. Obtained normal values in our study are comparable with local reference range reports from previous studies in Nigeria and other parts of Africa. 124947 .

HIV感染者/AIDS患者96例抗病毒治疗前后CD_4^+T细胞水平分析
