ABSTRACT Introduction: Skeletal muscle injuries stimulate a systemic inflammatory response which may interfere in species reproduction. Objective: To evaluate the effects caused by skeletal muscle injuries on the inflammatory response and sperm parameters of male adult rats. Methods: The sample group was composed of 30 Wistar rats distributed evenly across control and injury groups. Muscle injury was induced by bruising, caused by the release of a 200 g weight from a height of 30 cm onto the gastrocnemius muscle. Blood (CBC and damage/muscle inflammation markers), muscle (oxidative stress) and gonad (sperm parameters) samples were collected 72h after the injury. Results: The muscle injury increased monocytes, creatine kinase, C-reactive protein, reactive oxygen species (ROS) concentration and lipid peroxidation. In contrast, the injury reduced antioxidant capacity against peroxyl radicals (ACAP), membrane integrity (36%) and sperm acrosome (33%). Membrane integrity and acrosome (p<0.05) correlate directly with ACAP (ρ=0.602; ρ=0.513 respectively) and inversely with monocytes (ρ=-0.703; ρ=-0.635, respectively), creatine kinase (ρ=-0.450; ρ=-0.603), C-reactive protein (ρ=-0.511; ρ=-0.703) and parameters of oxidative stress (ROS ρ=-0.703; ρ=-0.635; lipid peroxidation ρ=-0.494; ρ=-0.559). Conclusion: The acute systemic inflammatory response arising from skeletal muscle injury interferes in the male reproductive cell organelles (membrane and acrosome). Level of Evidence V; Experimental study.

Challenging Situation

Volumetric muscle loss (VML) is defined as a condition in which a large volume of skeletal muscle is lost due to physical insult. VML often results in a heightened immune response, resulting in significant long-term functional impairment. Estimates indicate that ~250,000 fractures occur in the US alone that involve VML. Currently, there is no active treatment to fully recover or repair muscle loss in VML patients. The health economics burden due to VML is rapidly increasing around the world. Immunologists, developmental biologists, and muscle pathophysiologists are exploring both immune responses and biomaterials to meet this challenging situation. The inflammatory response in muscle injury involves a non-specific inflammatory response at the injured site that is coordination between the immune system, especially macrophages and muscle. The potential role of biomaterials in the regenerative process of skeletal muscle injury is currently an important topic. To this end, cell therapy holds great promise for the regeneration of damaged muscle following VML. However, the delivery of cells into the injured muscle site poses a major challenge as it might cause an adverse immune response or inflammation. To overcome this obstacle, in recent years various biomaterials with diverse physical and chemical nature have been developed and verified for the treatment of various muscle injuries. These biomaterials, with desired tunable physicochemical properties, can be used in combination with stem cells and growth factors to repair VML. In the current review, we focus on how various immune cells, in conjunction with biomaterials, can be used to promote muscle regeneration and, most importantly, suppress VML pathology.

Information concerning the mechanisms underlying oxidative stress and low-grade inflammation in young healthy women predisposing eventually to future diseases is scarce. We investigated the relationship of oxidative stress and high-sensitivity C-reactive protein (hsCRP) in fertile-age women by oral combined contraceptive (OC) use. Caucasian Italian healthy non-obese women (n = 290; 100 OC-users; 190 non-OC-users; mean age 23.2 ± 4.7 years) were analyzed. Blood hydroperoxides, as oxidative stress biomarkers, were assessed by Free Oxygen Radical Test (FORT). Serum hsCRP was determined by an ultra-sensitive method (hsCRP). Markedly elevated oxidative stress (≥400 FORT Units) was found in 77.0% of OC-users and 1.6% of non-OC-users, odds ratio (OR) = 209, 95% CI = 60.9–715.4, p < 0.001. Elevated hsCRP levels ≥ 2.0 mg/L, considered risky for cardiovascular diseases (CVDs), were found in 41.0% of OC-users and 9.5% of non-OC-users, OR = 6.6, 95%CI 3.5–12.4, p < 0.001. Hydroperoxides were strongly positively correlated to hsCRP in all women (rs = 0.622, p < 0.001), in OC-users (rs = 0.442, p < 0.001), and in non-OC-users (rs = 0.426, p < 0.001). Women with hydroperoxides ≥ 400 FORT Units were eight times as likely to have hsCRP ≥ 2 mg/L. In non-OC-users only, hydroperoxides values were positively correlated with weight and body mass index, but negatively correlated with red meat, fish and chocolate consumption. Our research is the first finding a strong positive correlation of serum hydroperoxides with hsCRP, a marker of low-grade chronic inflammation, in young healthy women. Further research is needed to elucidate the potential role of these two biomarkers in OC-use associated side-effects, like thromboembolism and other CVDs.
