Abstract
Kidney disease is the fourth most common cause of non-AIDS-related mortality in people living with HIV. Combination antiretroviral therapy (cART) remains the cornerstone of treatment. However, little is known about the impact of cART on disease outcomes in patients with HIV-associated nephropathy (HIVAN) and HIV-immune complex kidney disease (HIVICK). This systematic review evaluates the impact of cART on progression to end-stage kidney disease (ESKD) and other outcomes in HIV-infected individuals. We conducted a literature search utilizing PubMed, and Cochrane database and 11 articles met inclusion criteria for analysis of which nine HIVAN studies showed decreased progression to ESKD or death for subjects when treated with cART versus those untreated. However, two studies showed no survival advantage with cART. Three HIVICK studies showed improvement in delaying ESKD in subjects on cART compared to untreated subjects. cART appeared to reduce the risk to ESKD or death in patients with both HIVAN and HIVICK.Entities:

Figure 1.Evolution of ART, HIV-associated mortality and inclusive dates of studies reviewed. Key: NRTI, nucleoside reverse-transcriptase inhibitors; PI, protease inhibitor; NNRTI, non-nucleoside reverse-transcriptase inhibitors; STR, single tablet regimen; INSTI: integrase nuclear strand inhibitors. The graph represents the death rate from people living with HIV in the United States from 1990 to 2017 recorded in deaths per 100,000 people. The early 1990s saw a significant surge in HIV cases. Three different drug classes: NRTI, PI, and NNRTI were available for use by the mid-1990s. Since then, there has been a significant drop in people living with HIV until 2017. Further, introducing several other medication classes including INSTI to disrupt different viral mechanisms has dramatically reduced viral load in people living with HIV. The early 2000s saw the advent of the first single-tablet regimens (STR), which have been prescribed widely. Shown are the years of each included study in our manuscript to provide perspective on the evolution of HIV related disease and the impact of ART on data observed for HIVAN, HIVICK and survival in people living with HIV.

| Publication | Study Duration | N | Outcomes | Conclusion |
|---|---|---|---|---|
| Bookholane et al Prospective Cohort Study, 2020 | 2002-2018 | 233 | 163/233 HIVAN patients received ART. There was a protective association of ART on renal outcomes in HIVAN patients (p = 0.008). HIVAN incidence saw an overall decreasing trend, with increase in ART usage noted during the study duration (p < 0.001) | HIVAN was the most common etiology of kidney disease in HIV patients in South Africa. There is a decrease in the total number of HIVAN patients over time, likely due to increased ART availability. |
| Halle et al Retrospective study, 2019 | 2007-2013 | 43 | 109/156 patients were HIV positive, of which 76 patients were on cART with a median CD4 count of 241 (117-438) cells/mm3. Patients on cART at the start of the study showed a better survival curve (p = 0.021) versus those not on cART. | HIVAN is the primary etiology, especially in HIV patients not taking c-ART, and they had a high mortality rate. |
| Bige et al Retrospective study, 2012 | 2000-2009 | 57 | 57 HIVAN patients were studied. After the loss of follow-up (6 patients), 51 patients completed the entire study. ESKD was seen in 58.8% of patients with median renal survival of 40 months. Additionally, the study did not show any association between HAART usage and better renal outcome, irrespective of viral suppression. | More than half of the studied HIVAN patients suffered from ESKD despite being treated with HAART. However, early recognition of the disease is vital to start c-ART and RAS blockers timely before irreversible renal injury occurs. |
| Post et al Retrospective study, 2008 | 1998-2004 | 61 | 61 HIVAN patients were studied. Out of which 60 were already on ART at the time of HIVAN diagnosis. Patients showed an 89% five years survival rate. | The study showed no additional benefit of early initiation of ART on renal function and viral suppression. However, overall patient survival improved. |
| Atta et al Cohort Study, 2006 | 1995- 2004 | 36 | Out of 263, 36 HIVAN patients were part of the study. Of which 26 HIVAN patients received ART. The study concluded that the renal survival was better in the group receiving ART compared to the non-treatment group (control) both in univariate (P = 0.025) and multivariate analysis (P <0.05), independent of CD4 count. | This study provides significant data favoring the use of ART in patients with HIVAN (p <0.05) and its positive impact on the renal function irrespective of CD4 count, plasma HIV RNA. The importance of early diagnosis and treatment of HIVAN played a massive role in preventing renal loss. |
| Abott et al Cohort Study, 2003 | 1996–2000 | 36 | 31 patients were on either ART or cART. There was no survival advantage in using the ART/cART (AHR, 0.62, p = 0.06). The study also showed that patients with HIVAN had an increased risk of mortality (AHR: 4.74, p < 0.01) compared to patients with other causes of ESKD. | ART use was underutilized in patients by the study population. Primary diagnosis of HIVAN carried a higher mortality risk when compared to other causes of ESKD. Variables including study population (post-ESKD patients), use of earlier regimens, small sample size, may have underpowered the study outcome. |
| Cosgrove et al Retrospective study, 2002 | 1996–2000 | 23 | A total of 23 HIVAN patients were identified and followed, of which 13 of 23 patients received HAART. At the end of the study, patients who received HAART showed better renal outcomes than those who didn't. | HIVAN patients who received c-ART had a stable renal function after the follow-up period compared to non-c-ART patients; they either showed worsening serum creatinine, renal failure leading to dialysis, or death. |
| Lucus et al Cohort Study, 2004 | 1989-2001 | 94 | The study focused on 94 patients with an incidence of HIVAN of 8 per 1000 person-years. There was a 60% reduction of HIVAN risk in patients on HAART. In addition, no patients developed HIVAN when HAART was initiated before the development of AIDS. | c-ART was associated with a decrease in HIVAN incidence. |

Summaries of all the Included Studies for HIVAN or HIVICK.
| Publication | Study Duration | N (HIVAN) | N (HIVICK) | Outcomes | Conclusion |
|---|---|---|---|---|---|
| Booth et al Multicentre Study, 2016 | 1998–2012 | 65 | 55 | 65 HIVAN and 55 HIVICK patients were identified via kidney biopsy. ART therapy was given to 33.9% and 58.2% respectively. After 48 weeks of follow-up, there was a significant drop in proteinuria in both groups (p < 0.0001). | HIVICK patients on ART with detectable viral load at the time of HIVICK diagnosis showed improved kidney function. |
| da Silva et al Cohort Study, 2016 | 2004- 2014 | 14 | 14 | 17 patients of HIVAN and 15 patients of HIVICK were followed up for a median of 25 months. Most patients (82%) were on ART. Specific data on individual groups was not available. Upon 2 years of follow up, significant increase in eGFR (p = 0.005), with trends towards increased CD4 cell counts (p = 0.170), and decreased viral loads (p = 0.390). | The inference of the study; HIVAN was the most common HIV-associated kidney disease. Patients with baseline CD4 cell count ≥200 cells/mm3 compared to <200 cells/mm3 had better kidney function by the end of the follow up (p = 0.003). |
| Szczech et al Retrospective Cohort Study, 2004 | 1995-2001 | 42 | 26 | 42 HIVAN and 26 non-HIVAN patients were studied. 27/42 of HIVAN patients were on ART therapy. There was no significant relation between the viral load and ART initiation in both HIVAN and non-HIVAN group. Lesions other than HIVAN were not associated with progression to renal replacement therapy (p = 0.06) compared to HIVAN patients-->use of ART was associated with slower progression to renal replacement therapy use (p = 0.03). | The study reported mortality benefit of using ART in HIVAN patients but also concluded that there was no benefit of ART on non-HIVAN patients. |
