<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 Impact

Abstract Background Substance use is common among people living with human immunodeficiency virus (PLWH) and a barrier to achieving viral suppression. Among PLWH who report illicit drug use, we evaluated associations between HIV viral load (VL) and reduced use of illicit opioids, methamphetamine/crystal, cocaine/crack, and marijuana, regardless of whether or not abstinence was achieved. Methods This was a longitudinal cohort study of PLWH from 7 HIV clinics or 4 clinical studies. We used joint longitudinal and survival models to examine the impact of decreasing drug use and of abstinence for each drug on viral suppression. We repeated analyses using linear mixed models to examine associations between change in frequency of drug use and VL. Results The number of PLWH who were using each drug at baseline ranged from n = 568 (illicit opioids) to n = 4272 (marijuana). Abstinence was associated with higher odds of viral suppression (odds ratio [OR], 1.4–2.2) and lower relative VL (ranging from 21% to 42% by drug) for all 4 drug categories. Reducing frequency of illicit opioid or methamphetamine/crystal use without abstinence was associated with VL suppression (OR, 2.2, 1.6, respectively). Reducing frequency of illicit opioid or methamphetamine/crystal use without abstinence was associated with lower relative VL (47%, 38%, respectively). Conclusions Abstinence was associated with viral suppression. In addition, reducing use of illicit opioids or methamphetamine/crystal, even without abstinence, was also associated with viral suppression. Our findings highlight the impact of reducing substance use, even when abstinence is not achieved, and the potential benefits of medications, behavioral interventions, and harm-reduction interventions.

Abstract Background An increased risk of cardiovascular disease (CVD) was reported in patients coinfected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV), without identifying factors associated with atherosclerotic CVD (ASCVD) events. Methods HIV–HCV coinfected patients were enrolled in the ANRS CO13 HEPAVIH nationwide cohort. Primary outcome was total ASCVD events. Secondary outcomes were coronary and/or cerebral ASCVD events, and peripheral artery disease (PAD) ASCVD events. Incidences were estimated using the Aalen-Johansen method. Factors associated with ASCVD were identified using cause-specific Cox proportional hazards models. Results At baseline, median age of the study population (n=1213) was 45.4 (interquartile range [IQR] 42.1−49.0) years and 70.3% were men. After a median follow-up of 5.1 (IQR 3.9−7.0) years, the incidence was 6.98 (95% confidence interval [CI] 5.19−9.38) per 1000 person-years for total ASCVD events, 4.01 (2.78−6.00) for coronary and/or cerebral events, and 3.17 (2.05−4.92) for PAD ASCVD events. Aging (hazard ratio [HR] 1.06, 95% CI 1.01−1.12), prior CVD (HR 8.48, 95% CI 3.14−22.91), high total cholesterol (HR 1.43, 95% CI 1.11−1.83), high-density lipoprotein cholesterol (HR 0.22, 95% CI 0.08−0.63), statin use (HR 3.31, 95% CI 1.31−8.38), and high alcohol intake (HR 3.18, 95% CI 1.35−7.52) were independently associated with total ASCVD events, while undetectable baseline viral load (HR 0.41, 95%CI 0.18−0.96) with coronary and/or cerebral events. Conclusion HIV–HCV coinfected patients experienced a high incidence of ASCVD events. Some traditional cardiovascular risk factors were the main determinants of ASCVD. Controlling cholesterol abnormalities and maintaining undetectable HIV viral load are essential to control cardiovascular risk.

ABSTRACT The relationship of the neutralizing activity (NA) profile of sera from human immunodeficiency virus (HIV)-infected individuals to the HIV viral load and the absolute CD4 count was examined. The NA of 24 serum samples against autologous isolates (AI) and HIV type 1 strain MN was examined. Three NA patterns were recognized. Nine sera neutralized both AI and MN (+/+), six sera neutralized MN but not AI (−/+), and nine sera failed to neutralize both AI and MN (−/−). The identification of the three neutralization patterns (+/+, −/+, and −/−) indicated that resistance to neutralization was progressive. A reciprocal relationship between the viral burden of the patients and the NA profiles was observed. The nine subjects with a −/− NA profile had a plasma viral load of ≥5 × 104 copies/ml and a cellular viral burden of ≥1,122 infectious units per million viable cells, which were significantly different from those of the other groups (P < 0.02). These patterns were independent of the phenotypic characteristics of the virus. Longitudinally, subjects with a −/− profile at baseline gained their HIV-specific NA by 24 weeks of antiretroviral therapy when this was associated with a ≥1-log10 decline in the plasma HIV viral load. The sera from week 24 from some patients were able to neutralize both the 24-week and the baseline dominant virus isolates. A change in CD4 cell count of 50 or more in either direction predicted a −/− or +/+ profile. The verification of the autologous NA profile might be important in selecting patients who may benefit from immune-based therapies involving neutralizing monoclonal antibodies.
