Abstract
Hand-foot syndrome (HFS) is a common side effect of fluoropyrimidine anticancer drugs and often becomes a dose-limiting manifestation of toxicity once it occurs. The precise mechanism of HFS remains unclear, and effective measures to prevent or relieve it are currently limited. To investigate the pathogenesis of HFS and effective measures for treating or preventing it, establishment of animal models is crucial. Here, we gave male SD rats 170 mg/kg of tegafur (prodrug of 5-FU) daily for 35 days and evaluated their clinical and histopathological characteristics and pain-related behavioral tests. TUNEL-positive apoptotic cells and 5-FU concentrations in the plantar skin were also evaluated to investigate the mode of toxicity. Tegafur treatment induced hypersensitivity to mechanical pressure on the plantar surface beginning in Week 3, with decreased locomotor activity. Focal desquamation of the plantar skin was observed almost concomitantly and gradually worsened to palmar and plantar skin thickening with severe desquamation, cracks, or both. Histopathological lesions in the plantar skin at treatment end included desquamation and thickening, with epidermal cell swelling and spongiosis and focal inflammation in the dermis. The time-course of development and the characteristics of the tegafur-induced skin lesions were highly similar to those in human fluoropyrimidine-induced HFS, indicating that a HFS rat model was successfully established. Localized high concentrations of 5-FU in the palmar and plantar skin, with increased apoptosis, are likely involved in the mode of toxicity. Our model should clarify the pathogenesis of HFS, providing new insights into the best supportive care and prevention.

Pharmaceutical and clinical studies of celecoxib topical hydrogel for management of chemotherapy-induced hand-foot syndrome. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2023; 396:1571-1581. [PMID: 36418469 DOI: 10.1007/s00210-022-02339-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Accepted: 11/10/2022] [Indexed: 11/25/2022]
Abstract
Hand-foot syndrome (HFS) can be categorized as a frequent dose-limiting side effect following administration of chemotherapeutic agents, which needs an effective medication to avoid dose reduction or discontinuation. Oral celecoxib has been proved to be the best pharmacological intervention to ameliorate the skin lesions. However, due to reported gastrointestinal and cardiovascular toxicity following its long-term administration, celecoxib topical application would be a safe alternative for skin disorders. In this work, first, we formulated and optimized a topical hydrogel of celecoxib (1%) and then we investigated its efficacy in the management of chemotherapy-induced HFS in cancer patients. Optimized hydrogel showed acceptable results for drug content, pH, rheology, and stability. Analyzing in vitro drug release study by various mathematical models, the optimized hydrogel showed a zero-order release pattern with 93.27 ± 1.56% cumulative celecoxib release within 8 h. Ex vivo permeation studies across Wistar rat skin indicated suitable skin retention of celecoxib for topical delivery. Twenty-nine patients suffering from HFS were randomized to receive celecoxib and the placebo hydrogels 2 times a day for 3 weeks. At the baseline and at the end of the trial, HFS grades were determined. No serious adverse events occurred in patients who completely followed the instructions. No statistically significant differences between two arms were observed at the baseline (p value = 0.38). By contrast, Wilcoxon signed-rank test showed significant differences when secondary grades (p value = 0.05) and grade differences (p values < 0.001) were analyzed. Overall, the study proved that celecoxib hydrogel could be a promising intervention to manage HFS side effect.

Mitochondria-Targeted Triphenylphosphonium-Hydroxytyrosol Prevents Lipotoxicity-Induced Endothelial Injury by Enhancing Mitochondrial Function and Redox Balance via Promoting FoxO1 and Nrf2 Nuclear Translocation and Suppressing Inflammation via Inhibiting p38/NF-кB Pathway. Antioxidants (Basel) 2023; 12:antiox12010175. [PMID: 36671037 PMCID: PMC9854738 DOI: 10.3390/antiox12010175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Revised: 01/05/2023] [Accepted: 01/06/2023] [Indexed: 01/14/2023] Open
Abstract
Hyperlipidemia results in endothelial dysfunction, which is intimately associated with disturbed mitochondrial homeostasis, and is a real risk factor for cardiovascular diseases (CVDs). Triphenylphosphonium (TPP+)-HT, constructed by linking a mitochondrial-targeting moiety TPP+ to hydroxytyrosol (HT), enters the cell and accumulates in mitochondria and is thus an important candidate drug for preventing hyperlipidemia-induced endothelial injury. In the present study, we found that TPP-HT has a better anti-inflammatory effect than HT. In vivo, TPP-HT significantly prevented hyperlipidemia-induced adverse changes in the serological lipid panel, as well as endothelial and mitochondrial dysfunction of the thoracic aorta. Similarly, in vitro, TPP-HT exhibited similar protective effects in palmitate (PA)-induced endothelial dysfunction, particularly enhanced expression of the mitochondrial ETC complex II, recovered FoxO1 expression in PA-injured human aorta endothelial cells (HAECs) and promoted FoxO1 nuclear translocation. We further demonstrated that FoxO1 plays a pivotal role in regulating ATP production in the presence of TPP-HT by using the siFoxO1 knockdown technique. Simultaneously, TPP-HT enhanced Nrf2 nuclear translocation, consistent with the in vivo findings of immunofluorescence, and the antioxidant effect of TPP-HT was almost entirely blocked by siNrf2. Concomitantly, TPP-HT’s anti-inflammatory effects in the current study were primarily mediated via the p38 MAPK/NF-κB signaling pathway in addition to the FoxO1 and Nrf2 pathways. In brief, our findings suggest that mitochondria-targeted TPP-HT prevents lipotoxicity induced endothelial dysfunction by enhancing mitochondrial function and redox balance by promoting FoxO1 and Nrf2 nuclear translocation.
