Objective:The objective of this study is to estimate life expectancies of HIV-positive patients conditional on response to antiretroviral therapy (ART).Methods:Patients aged more than 20 years who started ART during 2000–2010 (excluding IDU) in HIV clinics contributing to the UK CHIC Study were followed for mortality until 2012. We determined the latest CD4+ cell count and viral load before ART and in each of years 1–5 of ART. For each duration of ART, life tables based on estimated mortality rates by sex, age, latest CD4+ cell count and viral suppression (HIV-1 RNA <400 copies/ml), were used to estimate expected age at death for ages 20–85 years.Results:Of 21 388 patients who started ART, 961 (4.5%) died during 110 697 person-years. At start of ART, expected age at death [95% confidence interval (CI)] of 35-year-old men with CD4+ cell count less than 200, 200–349, at least 350 cells/μl was 71 (68–73), 78 (74–82) and 77 (72–81) years, respectively, compared with 78 years for men in the general UK population. Thirty-five-year-old men who increased their CD4+ cell count in the first year of ART from less than 200 to 200–349 or at least 350 cells/μl and achieved viral suppression gained 7 and 10 years, respectively. After 5 years on ART, expected age at death of 35-year-old men varied from 54 (48–61) (CD4+ cell count <200 cells/μl and no viral suppression) to 80 (76–83) years (CD4+ cell count ≥350 cells/μl and viral suppression).Conclusion:Successfully treated HIV-positive individuals have a normal life expectancy. Patients who started ART with a low CD4+ cell count significantly improve their life expectancy if they have a good CD4+ cell count response and undetectable viral load.

Objectives To estimate life expectancy for people with HIV undergoing treatment compared with life expectancy in the general population and to assess the impact on life expectancy of late treatment, defined as CD4 count <200 cells/mm 3 at start of antiretroviral therapy.Design Cohort study.Setting Outpatient HIV clinics throughout the United Kingdom.Population Adult patients from the UK Collaborative HIV Cohort (UK CHIC) Study with CD4 count ≤350 cells/mm 3 at start of antiretroviral therapy in 1996-2008.Main outcome measures Life expectancy at the exact age of 20 (the average additional years that will be lived by a person after age 20), according to the cross sectional age specific mortality rates during the study period.Results 1248 of 17 661 eligible patients died during 91 203 person years' follow-up. Life expectancy (standard error) at exact age 20 increased from 30.0 (1.2) to 45.8 (1.7) years from 1996-9 to 2006-8. Life expectancy was 39.5 (0.45) for male patients and 50.2 (0.45) years for female patients compared with 57.8 and 61.6 years for men and women in the general population (1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006) Conclusions Life expectancy in people treated for HIV infection has increased by over 15 years during 1996-2008, but is still about 13 years less than that of the UK population. The higher life expectancy in women is magnified in those with HIV. Earlier diagnosis and subsequent timely treatment with antiretroviral therapy might increase life expectancy. IntroductionHIV infection has become a chronic disease with a good prognosis provided treatment is started sufficiently early in the course of the disease and the patient is able to maintain lifelong adherence to antiretroviral therapy. 1 2 Mortality rates have decreased such that, compared with the general population, the risk of death in successfully treated patients is similar to that of people with unhealthy lifestyles (such as heavy smoking, drinking, or obesity) or other chronic conditions such as diabetes.3 Although previous studies have compared mortality rates in patients with HIV with those in the general population [3][4][5][6] or have reported the prognosis of patients with HIV by estimating cumulative probability of death, 7 few have estimated how long those with HIV are likely to live.Estimates of life expectancy are important to individuals who want to plan their lives better, to service providers, and to policy makers. Patients might use this information to inform decisions on when they start antiretroviral therapy and treatment of comorbidities, pension provision, starting a family, or buying a house. Service providers require estimates of life expectancy to project the number of people with HIV who will need treatment and the future costs of providing antiretroviral therapy. Policy makers in the health service will be interested in addressing inequalities in life expectancy between patients with different characteristics, such as race or sex, or between those with early or delayed initia...

Patients infected with prevalent non-B subtypes were as likely to achieve viral load suppression as persons infected with subtype B and showed comparable rates of CD4 cell count recovery. HAART achieves excellent outcomes regardless of the infecting subtype.

Background. Tenofovir disoproxil fumarate (TDF) has been linked to renal impairment, but the extent to which this impairment is reversible is unclear. We aimed to investigate the reversibility of renal decline during TDF therapy.Methods. Cox proportional hazards models assessed factors associated with discontinuing TDF in those with an exposure duration of >6 months. In those who discontinued TDF therapy, linear piecewise regression models estimated glomerular filtration rate (eGFR) slopes before initiation of, during, and after discontinuation of TDF therapy. Factors associated with not achieving eGFR recovery 6 months after discontinuing TDF were assessed using multivariable logistic regression.Results. We observed declines in the eGFR during TDF exposure (mean slopes, −15.7 mL/minute/1.73 m2/year [95% confidence interval {CI}, −20.5 to −10.9] during the first 3 months and −3.1 mL/minute/1.73 m2/year [95% CI, −4.6 to −1.7] thereafter) and evidence of eGFR increases following discontinuation of TDF therapy (mean slopes, 12.5 mL/minute/1.73 m2/year [95% CI, 8.9–16.1] during the first 3 months and 0.8 mL/minute/1.73 m2/year [95% CI, .1–1.5] thereafter). Following TDF discontinuation, 38.6% of patients with a decline in the eGFR did not experience recovery. A higher eGFR at baseline, a lower eGFR after discontinuation of TDF therapy, and more-prolonged exposure to TDF were associated with an increased risk of incomplete recovery 6 months after discontinuation of TDF therapy.Conclusions. This study shows that a decline in the eGFR during TDF therapy was not fully reversible in one third of patients and suggests that prolonged TDF exposure at a low eGFR should be avoided.

Objectives Patients starting highly active antiretroviral therapy (HAART) may have a suboptimal CD4 increase despite rapid virological suppression. The frequency and the significance for patient care of this discordant response are uncertain. This study was designed to determine the incidence of a discordant response at two time‐points, soon after 6 months and at 12 months, and to determine the relationship with clinical outcomes. Methods Data obtained in the UK Collaborative HIV Cohort Study were analysed. A total of 2584 treatment‐naïve patients starting HAART with HIV viral load (VL)>1000 HIV‐1 RNA copies/mL at baseline and <50 copies/mL within 6 months were included in the analysis. Patients were classified at either 6–10 (midpoint 8) months or 10–14 (midpoint 12) months as having a discordant (CD4 count increase <100 cells/μL from baseline) or concordant response (CD4 count increase ≥100 cells/μL). Results Discordant responses occurred in 32.1% of patients at 8 months and in 24.2% at 12 months; 35% of those discordant at 8 months were concordant at 12 months. A discordant response was associated with older age, lower baseline VL, and (at 12 months) higher baseline CD4 cell count. In a multivariate analysis it was associated with an increased risk of death, more strongly at 12 months [incidence rate ratio (IRR) 3.35, 95% confidence interval (CI) 1.73–6.47, P<0.001] than at 8 months (IRR 2.08, 95% CI 1.19–3.64, P=0.010), but not with new AIDS events. Conclusions Discordant responders have a worse outcome, but assessment at 12 months may be preferred, given the number of ‘slow’ responders. Management strategies to improve outcomes for discordant responders need to be investigated.
