Objectives: Estimate tuberculosis (TB) incidence among patients receiving HAART. Compare the dynamic of the CD4-cell count and viral load before notification of the TB with the dynamic among patients remaining free of TB. Design: Prospective cohort with ascertainment of TB cases from medical records. Methods: The first 404 adults HIV-1 infected patients enrolled in the Senegalese antiretroviral drug access initiative were eligible. CD4-cell and viral load were assessed at baseline and every 6 months. Patients receiving an antituberculosis treatment at HAART initiation were excluded from analysis. Any TB case notified after the first month of HAART was considered as an incident case. Follow-up was censored at death or at the last visit before March 31, 2008. CD4-cell trajectories until TB notification were compared to non-TB developers within two distinct periods: from HAART initiation to 24 months and after. Results: Over 404 eligible patients, 352 were included in this analysis. Median follow-up reached 73 months and 1821 person-years were accrued. Half of the 42 incident cases were notified before month 19 of HAART yielding to an overall incident rate of 2.3/100 PY [1.7-3.1]. Annual incidence decreased with duration of HAART (trend in incidence: RR=0.26, p<10-4). During the first period, CD4-cell count dynamic of most TB patients was identical to the dynamic among patients remaining free of TB. Most cases of the second period occurred in a context of an immunological failure. Conclusions: This study provides an estimate of TB incidence among patients on HAART in Senegal and supports two underlying mechanisms.

<b><i>Objectives:</i></b> The aim of present work was to assess cytomegalovirus (CMV) viremia in Iranian human immunodeficiency virus (HIV)-1-infected patients with a CD4+ count &#x3c;100 cells/mm<sup>3</sup> and to explore whether CMV DNA loads correlate with CD4+ cell counts or associated retinitis. <b><i>Methods:</i></b> This study was conducted at the AIDS research center in Iran on HIV-1-infected patients with CD4+ count &#x3c;100 cells/mm<sup>3</sup>, antiretroviral therapy-naive, aged ≥18 years with no previous history of CMV end-organ disease (CMV-EOD). <b><i>Results:</i></b> Thirty-nine of 82 patients (47.56%) had detectable CMV viral load ranging from 66 to 485,500 IU/mL. CMV viral load in patients with retinitis ranges from 352 to 2,720 IU/mL, and it was undetectable in 2 patients. No significant associations between CMV viremia and CD4+ cell count was found (<i>p</i> value = 0.31), whereas significant association of CMV viremia in HIV-infected patients with retinitis was found (<i>p</i> &#x3c; 0.02). <b><i>Conclusions:</i></b> We estimated the frequency of CMV viral load infection in Iranian HIV-1-infected patients with a CD4+ cell count &#x3c;100 mm<sup>3</sup>/mL in the largest national referral center for HIV-1 infection in Iran. Further research is required on the relevance of CMV viral load in diagnostic and prognostic value of CMV-EOD.

The objective of the study was to investigate risk factors for the development of non-Hodgkin's lymphoma (NHL) in HIV-infected patients with hepatitis С virus (HCV) coinfection. A total of 37 HIV-positive subjects with NHL treated in the Moscow Center for Prevention and Control of AIDS between 2009 and 2013 were included in the study. HIV patients were divided into 2 groups: 23 cases with HCV coinfection and 14 patients without HCV coinfection. At the time of making the diagnosis of NHL 90% of patients had CD4 cell count < 350 cell/mm 3. The mean CD4 cell count in the first group (120±123 cell/mm 3) was significantly lower (p=0,035), than in patients without HCV coinfection (267±253 cell/mm3). At the time of making the diagnosis of NHL 70% of patients had HIV viral load ≥5,00 log10. The mean viral load was 5,47±1,09 log10 copies/ml in the first group and 4,06±2,03 log10 copies/ml in the second group (p=0,033). At the time of making the diagnosis of NHL 78% of patients did not receive combination antiretroviral therapy (cART). In most patients who received cART virologic suppression unsufficient and CD4 cell count remained to be low. Risk factors associated with an increased risk of NHL in HIV-infected patients with HCV coinfection are low CD4 cell count, high HIV viral load and lack of effective cART. Timely initiation of cART followed by complete virologic suppression and CD4 recovery are key factors to prevent NHL in HIV-infected patients.

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.
