Background: Globally 36.7 million people living with HIV, 1.8 million new HIV infection, and 1 million AIDS-related deaths in 2016.Patient mortality was high during the first 6 months after therapy for all patient subgroups and exceeded 40 per 100 patient years among patients who started treatment at low CD4 count. The aim this study was to evaluate the trend of CD4 cell count over time and to determine the progress of patient characteristics measured at baseline on CD4 cell count of HIV-infected patients who were under ART treatment in Arba Minch Hospital.  Methods: This study was retrospective follow up study using data extracted from medical records, patient interviews, and laboratory work-up. The study was employed among 550 adult patients that were selected by simple random sampling. The continuous outcome variable CD4 cell count has measured at months 0, 6, 12, 18, and 24. Longitudinal data analysis were used because the set of measurements on one patient tend to be correlated, measurements on the same patient close in time tend to be more highly correlated than measurements far apart in time, and the variability of longitudinal data often changes with time and the data handled through linear mixed effect models. Result: The fitted result of the linear mixed model showed that linear visit time effect and the baseline characteristics education status, condom, tobacco, degree of Disclosure, and weight effects had significant effect on CD4 measurements. Also, the interaction age with linear visit time effect had significant effect on the evolution of CD4 cell count. However, no significant difference between sex, WHO stage, and marital status groups. Conclusion: This study find that the CD4 cell count of HIV/AIDS patients is significantly determined by the visit time, education status, condom, tobacco, degree of Disclosure, and weight effects of patients.

Universal HIV screening and treatment initiation of HIV-positive persons are well-established standards. However, late presentation to care is a barrier to early antiretroviral therapy (ART) and prevention of HIV transmission. We sought to determine the immunodeficiency at presentation to care and characterize the initiation and response to ART among HIV-positive persons over 2003–2013 in our urban HIV clinical practice at the Cleveland Clinic. Using a retrospective cohort study design, we assessed the CD4 cell count of HIV-positive patients at entry into care for each year and evaluated the trend over time. For patients who initiated treatment, we assessed the pretreatment CD4 cell count, consistency of timing and regimen with US treatment guidelines, and HIV RNA level at one-year and last follow-up visits. Regression analyses were used to determine predictors of study outcomes. We found that the cohort (N = 452) median CD4 cell count at presentation to care was 297 cells/mm3 (inter-quartile range: 104–479 cells/mm3), without any significant change over time (P = 0.62), and with 37% and 21% of presentations being late and advanced, respectively. Guideline-consistency (85%–100%) and regimen-consistency (41%–100%) were moderate to high and improved over time. Virologic suppression (<400 copies/ml) at one year and last follow-up was high (79% and 92%) and associated with regimen selection and durability. We conclude that CD4 cell count at first presentation to HIV care remained less than 350 cells/mm3 for 11 years in our clinical practice, despite advances in HIV testing and treatment guidelines. Early diagnosis and linkage to care and treatment are critical for ending the HIV epidemic.

Abstract Background: Adolescents living with perinatally-acquired HIV (APHIV) face challenges including timely disclosure of their HIV-serostatus that was explored in the West-African COHADO cohort. We assessed the 24-month outcomes in COHADO, among APHIV in relation to the disclosure of their own HIV-serostatus.Methods: Nested within the International epidemiologic Database to Evaluate AIDS pediatric West African prospective cohort (IeDEA pWADA), the COHADO cohort included antiretroviral (ART)-treated APHIV aged 10–19 years, enrolled in HIV-care <10 years, in Abidjan (Côte d’Ivoire) and Lomé (Togo) in 2015. A favorable 24-month outcome was defined when combining being retained in care, without progression to WHO-AIDS stage, with CD4 cell count > baseline CD4 (± 10%) and with virological suppression (viral load [VL] <50 copies/mL). We investigated correlates of APHIV favorable 24-month outcome using multivariate logistic regression. Results: Overall, 209 APHIV were included, 51.6% in Abidjan, 54.5% were females. At inclusion, median CD4 cell count was 521/mm3 (IQR[281-757]); only 29.6% had a VL measurement of whom 3.2% in virological suppression. APHIV were younger in Lomé (median age: 12 years (interquartile range [IQR]:11-15) compared to Abidjan (14 years (IQR:12-15, p=0.01). Full HIV-disclosure increased from 41.6% at inclusion to 74.1% after 24 months. After 24 months of follow-up, 6 (2.9%) died, 8 (3.8%) were lost to follow-up, 4 (1.9%) were transferred out. Overall, 73.7% did not progress to WHO-AIDS stage, 62.7% had CD4 count above (± 10%) of the baseline value (48.6% in Abidjan versus 69.0% in Lomé, p<0.001). Among the 83.7% with VL measurements, 48.8% were in virological suppression (Abidjan: 45.4%, Lomé: 52.5%, p<0.01). The 24-month combined outcome was favorable for 45% (29.6% in Abidjan and 61.4% in Lomé, p<0.01). Adjusted on sex, age, a 24-month favorable outcome was not associated with HIV-disclosure status but was significantly higher for APHIV living in Lomé compared to those living Abidjan (adjusted odds ratio =4.41, 95%CI:2.29-8.50). Conclusions: 24-month favorable outcome rates were low among West-African APHIV and differed accross countries. HIV-disclosure frequency improved over time but remained low. Context-specific responses are urgently needed to improve adolescent’s care to reach the UNAIDS 90% target of virological success for those on ART.

Background CD4 lymphocyte cell count represents the main immunological marker used to monitor HIV infection. However, frequent monitoring may be unnecessary, could cause anxiety to the patient as well as burdening healthcare with extra expenses.   Objectives and methods To analyse the probability of maintaining a safe number of CD4 in HIV-positive subjects under treatment with ≥350 cells/µl at baseline during a three-year follow up. We conducted a retrospective study performing three analyses with Kaplan-Meyer method considering: 1) all patients independently from their viral load (VL); 2) patients with 500 > CD4 ≥ 350 cells/µl versus (vs) CD4 ≥ 500 cells/µl at baseline; 3) patients with VL < 20 copies/ml vs VL > 20 copies/ml.   Results 253 subjects were enrolled. The median CD4 count was 623 (489-805) cells/µl. Subjects maintaining ≥ 350 cells/µl in the first, second and third year were respectively 238 (94.1%), 229 (90.5%) and 226 (89.3%), independently from VL. Within subjects with ≥ 350 CD4/µl vs ≥ 500 CD4/µl at baseline, those who maintained ≥ 350 cells/µl until the third year were respectively 241 (95.3%) and 158 (98.1%). The probability of maintaining these values in the third year was 89.3% for those who had CD4 ≥ 350/µl at baseline and 98.1% for those who had CD4 ≥ 500/µl. This probability was around 90% vs 99% for subjects with HIV-RNA above or below 20 copies/ml. Secondly, we tried to estimate the costs of CD4 determinations in a three-year period (from April 1, 2013 to March 31, 2016). We analysed respectively 343 subjects in the first period, 364 in the second and 383 in the third, with a median value of 500 CD4/µl during the research time taken into account. We found a mean value of about two determinations patient/year (2.41 in 2013/2014; 2.32 in 2014/2015; 2.18 in 2015/2016), with a significant decrease between the first and the last period (p<0.001). The mean cost patient/year was €101.51 in the first year, €97.61 in the second, €92.00 in the third (p<0,001). Assuming to extend these procedures to all our patients with stable CD4 cells/µl and monitoring CD4 cell count once in a year, it could be possible to obtain an overall saving of €19,152/year.   Conclusions A very high percentage of subjects maintained a high and safe number of CD4 cells (>350 cells/µl) during a three-year follow up. It could be possible to save up to 66% of the costs by reducing the number of CD4 count determinations in a year, to have other favourable consequences as well, releasing new resources for patient’s management.

In September 2015, the World Health Organization updated their guidelines to recommend antiretroviral therapy (ART) for all people living with HIV. Countries are now in the process of implementing strategies to provide universal HIV treatment. We analyzed the rate of retention and time to ART eligibility (according to 2013 WHO guidelines) among 3,345 adult patients receiving positive HIV test results between February 1, 2003 and March 31, 2013 at the GHESKIO Clinic in Haiti, with WHO stage 1 or 2 disease and initial CD4 cell count >500 cells/mm3. Among the 3,345 patients, 2,423 (72%) were female, the median age was 33 years, 3,089 (92%) lived in Port-au-Prince, and 1,944 (58%) had attended no school or primary school only. The median initial CD4 cell count was 668 cells/mm3 (IQR: 572-834); over the subsequent 2 years, 1,485 patients (44%) were lost to follow-up and 7 (<1%) died pre-ART, 1,041 (31%) were retained in pre-ART care, and 819 (24%) initiated ART. In multivariate analysis, secondary education (aOR 1.27; 95% CI: 1.10-1.47), female gender (aOR: 1.28; 95% CI: 1.09-1.50), co-habitation (aOR: 1.31; 95% CI: 1.09-1.57), and residence in Port-au-Prince (aOR: 1.43; 95% CI: 1.09-1.88) were associated with retention in care. The median time from baseline CD4 count to ART eligibility was 1.7 years. Prior to the implementation of universal treatment, pre-ART attrition was high among patients who did not qualify for ART at presentation. Though implementing WHO recommendations for universal ART will require service expansion, it will likely result in improved retention for those at risk of being lost to follow-up.

AbstractAn obesity paradox has been proposed in many conditions including HIV. Studies conducted to investigate obesity and its effect on HIV disease progression have been inconclusive and are lacking for African settings. This study investigated the relationship between overweight/obesity (BMI≥25 kg/m2) and HIV disease progression in HIV+ asymptomatic adults not on antiretroviral treatment (ART) in Botswana over 18 months. A cohort study in asymptomatic, ART-naïve, HIV+ adults included 217 participants, 139 with BMI of 18·0–24·9 kg/m2 and seventy-eight participants with BMI≥25 kg/m2. The primary outcome was time to event (≥25 % decrease in cluster of differentiation 4 (CD4) cell count) during 18 months of follow-up; secondary outcomes were time to event of CD4 cell count<250 cells/µl and AIDS-defining conditions. Proportional survival hazard models were used to compare hazard ratios (HR) on time to events of HIV disease progression over 18 months. Higher baseline BMI was associated with significantly lower risk of an AIDS-defining condition during the follow-up (HR 0·218; 95 % CI 0·068, 0·701; P=0·011). Higher fat mass at baseline was also significantly associated with decreased risk of AIDS-defining conditions during the follow-up (HR 0·855; 95 % CI 0·741, 0·987; P=0·033) and the combined outcome of having CD4 cell count≤250/µl and AIDS-defining conditions, whichever occurred earlier (HR 0·918; 95 % CI 0·847, 0·994; P=0·036). All models were adjusted for covariates. Higher BMI and fat mass among the HIV-infected, ART-naïve participants were associated with slower disease progression. Mechanistic research is needed to evaluate the association between BMI, fat mass and HIV disease progression.

Abstract Background: Human immunodeficiency virus attacked an immune cell and the CD4 cell which is responsible for the body’s immune to infectious agents. Acquired immunodeficiency syndrome is one of the major public health problems in Sub-Saharan Africa including Ethiopia. The main objective of this study to identify the determinants of CD4 cell count among antiretroviral therapy attendants of infected adults follow up in Gonder teaching referral hospital, Gonder, Ethiopia implemented by SAS version 94. Methods: A retrospective cohort study was conducted on 216 regular follow up patients whose age greater than 14 years from December 1, 2012, to December 30, 2017. A multilevel model was used to identify the factors of CD4 cell count of patients and it considered variability between and within patients. Results: The mean with a standard deviation of weight, and a hemoglobin level of patients were 55.48(10.21), and 18.25(33.028) respectively. This study concluded that the variation for CD4 cell count existed between patients was 63 % and the remaining 37 % of variation existing within patients. In this study, the random coefficient time-varying covariate model was well fitted which shows weight and hemoglobin level were statistically significant predictors at a 5% level of significance for the log of CD4 cell count of patients. Conclusion: This study shows the hemoglobin level and weight of patients were statistically significant for the log of CD4 cell count of patients follow up in Gonder teaching referral hospital, Gonder, Ethiopia. Moreover, the result of the study shows that the log of CD4 count of patients increased when hemoglobin level and weight of patients increased. Hence, intervention should be given the ways to increase weight and hemoglobin levels of patients during follow up antiretroviral therapy.
