Abstract
OBJECTIVE To describe the successful conservative management of chemical pneumonitis and presumed acute respiratory distress syndrome in a cat secondary to inadvertent pulmonary polyethylene glycol-electrolyte solution (PEG-ELS) instillation. CASE SUMMARY PEG-ELS is commonly used in small animals for bowel cleansing and to treat constipation. There have been several instances of aspiration or accidental instillation of this solution into the lungs of both people and dogs. PEG-ELS was inadvertently infused into the lungs of the cat in the current report. After 10 days in the ICU, during which time treatment with oxygen therapy, antibiosis, diuretics, and corticosteroids was provided, the cat was successfully discharged. NEW OR UNIQUE INFORMATION PROVIDED To the authors' knowledge, this is the first report of instillation of PEG-ELS in a cat resulting in chemical pneumonitis and lung injury. We describe the successful management of this condition with conservative management and without the need for invasive interventions such as bronchoscopy and lavage or mechanical ventilation.

Pulmonary injury and oxidative stress in rats induced by inhaled sulfur mustard is ameliorated by anti-tumor necrosis factor-α antibody. Toxicol Appl Pharmacol 2021; 428:115677. [PMID: 34390737 DOI: 10.1016/j.taap.2021.115677] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Revised: 08/07/2021] [Accepted: 08/09/2021] [Indexed: 11/20/2022]
Abstract
Sulfur mustard (SM) is a bifunctional alkylating agent that causes severe injury to the respiratory tract. This is accompanied by an accumulation of macrophages in the lung and the release of the proinflammatory cytokine, tumor necrosis factor (TNF)α. In these studies, we analyzed the effects of blocking TNFα on lung injury, inflammation and oxidative stress induced by inhaled SM. Rats were treated with SM vapor (0.4 mg/kg) or air control by intratracheal inhalation. This was followed 15-30 min later by anti-TNFα antibody (15mg/kg, i.v.) or PBS control. Animals were euthanized 3 days later. Anti-TNFα antibody was found to blunt SM-induced peribronchial edema, perivascular inflammation and alveolar plasma protein and inflammatory cell accumulation in the lung; this was associated with reduced expression of PCNA in histologic sections and decreases in BAL levels of fibrinogen. SM-induced increases in inflammatory proteins including soluble receptor for glycation end products, its ligand, high mobility group box-1, and matrix metalloproteinase-9 were also reduced by anti-TNFα antibody administration, along with increases in numbers of lung macrophages expressing TNFα, cyclooxygenase-2 and inducible nitric oxide synthase. This was correlated with reduced oxidative stress as measured by expression of heme oxygenase-1 and Ym-1. Together, these data suggest that inhibiting TNFα may represent an efficacious approach to mitigating acute lung injury, inflammatory macrophage activation, and oxidative stress induced by inhaled sulfur mustard.

Abstract
Public health issues have been raised regarding fructose toxicity and its serious metabolic disorders. Deleterious effects of high fructose intake on insulin sensitivity, body weight, lipid homeostasis have been identified. The new millennium has witnessed the emergence of a modern epidemic, the metabolic syndrome (MS), in approximately 25% of the world's adult population. The current study aimed to investigate the effect of the TNF-α antagonist infliximab on fructose-induced MS in rats. Rats were administered fructose (10%) in drinking water for 12 weeks to induce the experimental MS model. infliximab (5 mg/kg) was injected once weekly intraperitoneally starting on the 13th week for 4 weeks. Increase in body weight, blood glucose level, serum triglycerides (TGs), adiponectin level and blood pressure were present in MS rats. They also prompted increases in serum of leptin, TNF-α, and malondialdehyde (MDA) levels. Treatment with infliximab did not affect body weight, hyperglycemia or hypertension, but decreased serum TGs and increased serum HDL-c levels. Infliximab also decreased adiponectin levels. Surprisingly, infliximab increased MDA above its value in the MS group. These results reflect the fact that infliximab affects the manifestations of MS in rats. Though infliximab reduced TGs, increased HDL-c levels, reversed adiponectin resistance occurred by fructose, the drug failed to combat MS-mediated hyperglycemia, hypertension, and elevated MDA above the insult.

Abstract
OBJECTIVE Multiple rib fractures (RFs) and pulmonary contusions (PCs), with resulting systemic lung inflammation, are the most common injuries caused by blunt chest trauma (BCT) in motor vehicle accidents. This study examined levels of the inflammation marker interleukin (IL)-6 and those of the acute-phase reactant surfactant protein (SP)-D in patients with BCT. DESIGN Prospective, cross-sectional, observational study. SETTING Single-centre, tertiary care hospital in the Black Sea Region of Turkey. PARTICIPANTS The study included 60 patients with BCT who were hospitalised in our thoracic surgery department. PARAMETERS MEASURES The SP-D and IL-6 serum levels of patients with RFs (two or more RFs) (n=30) and patients with PCs (n=30) were measured after 6 hours, 24 hours and 7 days, and compared with those of age-matched and gender-matched healthy participants. RESULTS The 6-hour serum SP-D levels of the RFs (p=0.017) and PCs (p<0.001) groups were significantly higher than those of the healthy controls. The 24-hour and 7-day SP-D levels of both groups were also higher than the control group. The serum IL-6 levels of both groups were significantly higher than those of the control group. We have found Injury Severity Score to be independently related to 6-hour IL-6 (β=1.414, p<0.001) and 24-hour IL-6 levels (β=1.067, p<0.001). The development of complications was independently related to 6-hour SP-D level (β=0.211, p=0.047). CONCLUSIONS RFs and PCs after BCT lead to local and systemic inflammation due to lung injury. The levels of the systemic inflammation marker IL-6 and those of the acute-phase reactant SP-D were elevated in the present study. The SP-D level may be used as a marker in the follow-up of BCT-related complications.

Abstract
INTRODUCTION Methotrexate (MTX) is used to treat cancers, several forms of arthritis and other rheumatic conditions, although MTX may cause pulmonary toxicity related to the production of free oxygen radicals, various cytokines. Infliximab (IB) with its potent effect on tumor necrosis factor-alpha (TNF-α) inhibition also inhibits the release of endothelin-1 (ET-1). We aimed to investigate whether IB reduces pulmonary damage induced by an overdose of MTX. METHOD The rats were divided into 3 groups of 8 animals. The control group was given only saline. One dose of 20mg/kg MTX intraperitoneal was administered in the MTX group. IB 7 mg/kg was given to the MTX+IB (MI) group. Three days after IB was administered, 20mg/kg MTX was given. Five days after MTX was administered, all rats were sacrificed. RESULTS The TNF-α, ET-1, malondialdehyde (MDA), myeloperoxidase (MPO) and caspase-3 levels in MTX group were significantly higher than in control groups of TNF-α (P=.001), ET-1 (P=.001), MDA (P=.001), MPO (P=.001) and caspase-3 levels (P=.001) and MI groups of TNF-α (P=.009), ET-1 (P=.001), MDA (P=.047), MPO (P=.007) and caspase-3 levels (P=.003). The MI group had less histopathological damage in lung tissue than the MTX group. CONCLUSION Overdose of MTX leads to cytokine release and the formation of reactive oxygen species in addition to increased ET-1 secretion release that causes lung damage. IB, as a potent proinflammatory agent, TNF-α blocker, can decrease ET-1 release and oxidative stress, it may show significant protective effects in lung tissue against damage caused by MTX overdose.

Abstract
OBJECTIVES To investigate whether infliximab (Ib), an inhibitor of tumor necrosis factor alpha (TNF-α), prevents cisplatin (Cis)-induced nephrotoxicity. METHODS The study was performed in the Department of Internal Medicine, Recep Tayyip Erdogan University, Rize, Turkey, between November 2012 and May 2013. Thirty male Wistar albino rats were divided into 3 groups, a control group, a Cis group, and a Cis+Ib group. The animals of the Cis group were injected with a single dose (7 mg/kg) of Cis intraperitoneally. The animals of the Cis+Ib group were injected with a single dose (7 mg/kg) of Ib 72 hours prior to Cis injection. RESULTS The TNF-α, interleukin-1 beta (IL-1b), nitric oxide (NO) and adenosine deaminase (ADA) levels of the Cis group were higher than both the control group TNF-α (p<0.001), IL-1α (p<0.001), NO (p<0.001) and ADA (p<0.001), and the Cis+Ib group TNF-α (p<0.001), IL-1b (p<0.001), NO (p<0.001), and ADA (p=0.003). Histopathological examination revealed extensive damage in the Cis group, while the damage in the Cis+Ib group was lower. While the carbonic anhydrase II (CA-II) level of the Cis group was lower than both groups, it was similar in the Cis+Ib and the control groups. CONCLUSION Infliximab acts against Cis-induced nephrotoxicity by a strong inhibition of TNF-α. Additionally, the combination of these 2 drugs does not obviously change the level of CA-II.

Abstract
Pro-inflammatory cytokines have been proposed to be associated with the pathogenesis of depression. Consistent with this notion, several clinical observations have suggested the antidepressant efficacy of TNF-α inhibitors in patients with chronic inflammatory diseases. In this study, we evaluated the antidepressant and anxiolytic effects of chronic TNF-α inhibitor (infliximab, 5 mg/kg, i.p., weekly) administration in the chronic mild stress (CMS) model of depression. Rats were divided into three groups: saline-control (no stress), saline-CMS, and infliximab-CMS. Rats in the latter two groups were exposed to CMS for 8 weeks. Saline (former two groups) or infliximab was injected weekly during this period. After CMS, total locomotor activity, anxiety-like behaviour and depression-like behaviours were evaluated using automated locomotor activity cage, elevated plus maze (EPM), and sucrose preference (SPT) and forced swimming (FS) tests, respectively. As expected, the saline-CMS group exhibited higher depression-like behaviours in FS and SPT tests compared with the saline-control group. There were no differences between these two groups in terms of the anxiety-like behaviour or total locomotor activity. Infliximab reduced the depression-like behaviour of CMS rats compared with saline-CMS group, and anxiety-like behaviour of CMS rats compared with saline-CMS and saline-control groups. Our findings suggest that chronic and systemic TNF-α inhibition reduced depression and anxiety-like behaviour in the CMS model of depression in rats.
