Abstract
PURPOSE The number of patients with asymptomatic human immunodeficiency virus (AHIV) is increasing as the efficacy of antiretroviral therapy improves. While there is research on operative risks associated with having HIV, there is a lack of literature describing the impact of well-controlled HIV on postoperative complications. This study seeks to elucidate the impact of AHIV on postoperative outcomes after total hip (THA) and knee (TKA) arthroplasty. METHODS The Nationwide Inpatient Sample was retrospectively reviewed for patients undergoing TKA and THA from 2005 to 2013. Subjects were subdivided into those with AHIV and those without HIV (non-HIV). Patient demographics, hospital-related parameters, and postoperative complications were all collected. One-to-one propensity score-matching, Chi-square analysis, and multivariate logistical regressions were performed to compare both cohorts. RESULTS There were no significant differences between AHIV and non-HIV patients undergoing TKA or THA in terms of sex, age, insurance status, or total costs (all, p ≥ 0.081). AHIV patients had longer lengths of stay (4.0 days) than non-HIV patients after both TKA (3.3 days) and THA (3.1 days) (p ≤ 0.011). Both TKA groups had similar postoperative complication rates (p > 0.081). AHIV patients undergoing THA exhibited an increased rate of overall surgical complications compared non-HIV patients (0 vs. 4.5%, p = 0.043). AHIV was not associated with increased complications following both procedures. CONCLUSION Despite lengthier hospital stays among AHIV patients, baseline AHIV was not associated with adverse outcomes following TKA and THA. This adds to the literature and warrants further research into the impact of asymptomatic, well-controlled HIV infection on postoperative outcomes following total joint arthroplasty.

The Impact of Asymptomatic Human Immunodeficiency Virus-Positive Disease Status on Inpatient Complications Following Spine Surgery: A Propensity Score-Matched Analysis. J Clin Med 2023; 12:jcm12041458. [PMID: 36835993 PMCID: PMC9967388 DOI: 10.3390/jcm12041458] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 01/20/2023] [Accepted: 02/04/2023] [Indexed: 02/15/2023] Open
Abstract
In the United States, nearly 1.2 million people > 12 years old have human immunodeficiency virus (HIV), which is associated with postoperative complications following orthopedic procedures. Little is known about how asymptomatic HIV (AHIV) patients fare postoperatively. This study compares complications after common spine surgeries between patients with and without AHIV. The Nationwide Inpatient Sample (NIS) was retrospectively reviewed from 2005-2013, identifying patients aged > 18 years who underwent 2-3-level anterior cervical discectomy and fusion (ACDF), ≥4-level thoracolumbar fusion (TLF), or 2-3-level lumbar fusion (LF). Patients with AHIV and without HIV were 1:1 propensity score-matched. Univariate analysis and multivariable binary logistic regression were performed to assess associations between HIV status and outcomes by cohort. 2-3-level ACDF (n = 594 total patients) and ≥4-level TLF (n = 86 total patients) cohorts demonstrated comparable length of stay (LOS), rates of wound-related, implant-related, medical, surgical, and overall complications between AHIV and controls. 2-3-level LF (n = 570 total patients) cohorts had comparable LOS, implant-related, medical, surgical, and overall complications. AHIV patients experienced higher postoperative respiratory complications (4.3% vs. 0.4%,). AHIV was not associated with higher risks of medical, surgical, or overall inpatient postoperative complications following most spine surgical procedures. The results suggest the postoperative course may be improved in patients with baseline control of HIV infection.

[PMID: 27769179 PMCID: PMC5073883 DOI: 10.1186/s12879-016-1930-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2016] [Accepted: 10/13/2016] [Indexed: 02/06/2023] Open
Abstract
Background Symptomatic primary HIV infection is associated with an adverse prognosis, and immediate initiation of combination antiretroviral therapy (cART) is recommended. However, little is known about immunological predictors of immune recovery. Thymic Stromal Lymphopoietin (TSLP) is a cytokine that promotes CD4+ T cells homeostatic polyclonal proliferation and regulates Th17/regulatory T-cell balance, immunological functions known to be affected during primary HIV infection. The aim of this study was to describe immune recovery in primary and chronic HIV infection and possible impact of TSLP. Methods Prospective study including 100 HIV-infected individuals (primary HIV infection (N = 14), early presenters (>350 CD4+ T cells/μL, N = 42), late presenters without advanced disease (200–350 CD4+ T cells/μL, N = 24) and with advanced disease (<200 CD4+ T cells/μL, N = 20) and). Immune recovery was defined as increase in CD4+ T cells count from baseline to a given time of follow-up. Plasma TSLP was determined using ELISA and CD4+ T cell subpopulations (recent thymic emigrants, naïve and memory cells) were measured using flow cytometry at baseline and after 6, 12 and 24 months of cART. Results Immune recovery was comparable in all groups, and no differences in immune homeostasis were found between primary HIV infection and early presenters, whereas differences in absolute counts and proportions of CD4+ T cell subpopulations were found between primary HIV infection and late presenters. TSLP was elevated in primary HIV infection at baseline and after 24 months of cART. Interestingly, TSLP was negatively associated with proportion of recent thymic emigrants (correlation coefficient −0.60, p = 0.030). TSLP was not associated with immune recovery in primary HIV infection. Conclusions Immune recovery was comparable in primary and chronic HIV infection whereas differences in absolute counts and proportions of CD4+ T cell subpopulations were found between primary HIV infection and late presenters supporting early initiation of cART. Higher plasma TSLP was found in primary HIV infection, and TSLP was associated with lower thymic output, but not with immune recovery. These findings indicate a possible role of TSLP in immune homeostasis in HIV infection but do not support TSLP to affect immune recovery in primary HIV infection.
