Osteoarthritis (OA), a degenerative joint disease primarily affecting the hips and knees, is characterized by multifactorial dysregulation of chondrocyte homeostasis and currently lacks curative treatment options. Intra-articular hyaluronic acid (HA) injections have clinically provided symptomatic relief for three decades; however, HA's rapid in vivo degradation by free radicals and hyaluronidases limits its efficacy. We hypothesized that adding niacinamide (vitamin B3) to linear HA hydrogels would provide ancillary anti-inflammatory and anti-catabolic properties, thereby improving HA-based viscosupplementation therapy. This preliminary preclinical mechanistic study investigated the functional effects of incorporating niacinamide into linear HA-based hydrogels using in vitro cellular models. Initially, Raw 264.7 macrophages and C28/I2 or SW1353 human chondrocytes were pre-treated with varying concentrations of HA/B3, with or without lipopolysaccharide (LPS) or interleukin-1β (IL-1β), respectively. Subsequently, pro-inflammatory and pro-catabolic markers were quantified biochemically. Results demonstrated that HA/B3 hydrogels exhibited enhanced functional stability compared to HA alone and possessed significant anti-inflammatory and anti-catabolic properties, without inducing cytotoxicity in either cell line. In Raw 264.7 macrophages, HA/B3 inhibited LPS-induced tumor necrosis factor-α (TNF-α) release and suppressed cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) protein expression. In vitro, HA/B3 hydrogels reduced IL-1β-induced IL-6 production in primary chondrocytes by 16% and suppressed PGE2 concentration in both macrophages and chondrocytes by 60%, effects superior to HA alone. Finally, a rat primary articular chondrocyte model suggested slight anti-hypertrophic effects of HA/B3 in vitro. Collectively, these findings suggest that HA/B3 hydrogels possess anti-arthritic potential, highlighting a novel strategy for next-generation viscosupplement systems.

Background: Hypothermic machine perfusion (HMP) has been associated with reduced delayed graft function compared with static cold storage (SCS). However, the molecular mechanisms underlying these differences during cold preservation remain incompletely understood. This study compared cold-storage-related biochemical and histological changes in kidneys preserved by HMP versus SCS using a Lewis rat model prior to transplantation. Methods: Following isolation, rat kidneys were flushed with cold saline (4 °C). Left kidneys were preserved by HMP at constant flow using Belzer’s machine perfusion solution (MPS) at 4 °C, while right kidneys were stored using SCS in University of Wisconsin solution at 4 °C. After four hours of preservation, kidneys were processed for biochemical and histological analysis. Fresh biopsies were evaluated for mitochondrial complex respiration. Western blotting was performed to assess expression of NDUFS3, a complex I subunit. Histological staining for nitrotyrosine and kidney injury markers was compared across groups. Results: Mitochondrial complex respiration did not differ significantly between the SCS and HMP groups. Western blot analysis demonstrated significantly increased NDUFS3 expression in HMP-preserved kidneys compared with SCS and control kidneys. Histological evaluation revealed elevated tubular staining of nitrotyrosine and kidney injury markers in SCS kidneys relative to controls, whereas HMP preservation markedly attenuated these increases. Conclusions: HMP mitigates cold-storage-induced oxidative stress and reduces expression of kidney injury markers after four hours of preservation. These molecular findings suggest a protective effect of HMP during cold preservation. Future studies with longer preservation times and transplantation models are needed to determine whether these improvements translate into enhanced post-transplant kidney function.
