Abstract
Stress has been well-documented to have a significant role in the etiopathogenesis of bruxism. Activation of the hypothalamic-pituitary-adrenal axis (HPA) and subsequent release of corticosteroids lead to increased muscle activity. Neurological studies have demonstrated that chronic stress exposure induces neurodegeneration of important neuronal structures and destabilization of the mesocortical dopaminergic pathway. These disruptions impair the abilities to counteract the overactivity of the HPA axis and disinhibit involuntary muscle activity, while at the same time, there is activation of the amygdala. Recent evidence shows that overactivation of the amygdala under stressful stimuli causes rhythmic jaw muscle activity by over activating the mesencephalic and motor trigeminal nuclei. The present review aimed to discuss the negative effects of certain vitamin and mineral deficiencies, such as vitamin D, magnesium, and omega-3 fatty acids, on the central nervous system. It provides evidence on how such insufficiencies may increase stress sensitivity and neuromuscular excitability and thereby reduce the ability to effectively respond to the overactivation of the sympathetic nervous system, and also how stress can in turn lead to these insufficiencies. Finally, the positive effects of individualized supplementation are discussed in the context of diminishing anxiety and oxidative stress, neuroprotection and in the reversal of neurodegeneration, and also in alleviating/reducing neuromuscular symptoms.

Reveille JD. Biomarkers in axial spondyloarthritis and low back pain: a comprehensive review. Clin Rheumatol 2021; 41:617-634. [PMID: 34674081 DOI: 10.1007/s10067-021-05968-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Revised: 09/20/2021] [Accepted: 10/13/2021] [Indexed: 02/07/2023]
Abstract
The spectrum of axial spondyloarthritis (AxSpA) (including both non-radiographic and radiographic AxSpA), also known as ankylosing spondylitis AS, has achieved growing recognition. With the development of treatments not only effective in controlling disease activity but also in slowing radiographic progression, and given the cost and risk profiles of these novel treatments and the limitations of current clinical criteria, imaging and peripheral blood biomarkers (C-reactive protein, HLA-B27 testing), the need for better biomarkers has never been greater. The purpose of this review is to present up-to-date information on the biomarkers for the diagnosis for assessing disease diagnosis, activity, treatment response, and radiographic progression of AxSpA, and entails multiple search strings used to identify articles of interest published in PubMed and the Cochrane database up to May 1, 2021. We present the current status of research in serologic biomarkers such as cytokines, adipokines, matrix metalloproteinases, calprotectin, CD74, antibodies, bone turnover markers, and circulating protein fragments of cartilage and connective tissue degradation and other biomarkers. Despite a great deal of work, most serologic results have been disappointing and to date none perform better than CRP. Recent promising preliminary data for some has been published, but require further confirmation. Transcriptomic biomarkers such as micro-RNAs and genetic biomarkers also show promise to assist in diagnosis and possibly for radiographic severity, including a recently developed panel of genetic risk markers used in a polygenic risk score instrument in AS diagnosis. These need further confirmation and application in AS as well as in nr-AxSpA.

Ozcan-Kucuk A, Ege B, Koparal M, Gonel A, Koyuncu I. Evaluation of the Oxidative Stress Level and Serum Prolidase Activity in Patients with Sleep Bruxism. Comb Chem High Throughput Screen 2021; 24:286-293. [DOI: 10.2174/1386207323999200729114410] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Revised: 06/02/2020] [Accepted: 07/14/2020] [Indexed: 11/22/2022]
Abstract
Aims and Objective:
Sleep bruxism is a complicated disease, and its cause remains
controversial. If the etiology of bruxism is resolved, the treatment can be adjusted to the prevailing
aetiological factor. Thus, the aim of this study was to evaluate the oxidative stress level and serum
prolidase activity in patients with sleep bruxism.
Materials and Methods:
Seventy healthy subjects and 51 patients with sleep bruxism were
included in this study, and blood samples from all patients were collected. Serum samples were
analyzed for total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index
(OSI), and prolidase activity.
Results:
The prolidase, TOS, and OSI levels were significantly higher in patients with bruxism
than in the healthy controls (p = 0.001, p = 0.001, p = 0.001, respectively). The TAS level was
significantly lower in bruxism patients than in healthy controls (p = 0.003).
Conclusion:
The increased TOS, OSI, and prolidase levels and decreased TAS levels could be
assumed to result in oxidative injury in patients with sleep bruxism. However, the study could not
determine whether oxidative imbalance and increased serum prolidase levels could be a cause or a
result of bruxism.

Abstract
AbstractObjectivesThe severity of interstitial fibrosis/tubular atrophy (IFTA) is the most important determinant of the irreversible progression of chronic kidney disease (CKD). Prolidase is the key enzyme in collagen turnover and is associated with an extracellular matrix increase. We aimed to evaluate the relationship between the presence and degree of IFTA and serum prolidase enzyme activity (SPEA) in patients undergoing a renal biopsy.MethodsThis cross-sectional study included 56 patients who underwent a renal biopsy (30 males; mean age 45.3 ± 16.8 years) and also 54 healthy volunteers (21 males; mean age 42.7 ± 8.2 years). IFTA scoring was performed on the basis of percentage of IFTA presence in renal biopsy tissues (1=<10%; 2=10–24%; 3=25–50%; 4=>50%). SPEA was measured by spectrophotometric method.ResultsThe proteinuria and SPEA levels of the patients were significantly higher than the controls (p<0.001 and p<0.001, respectively). SPEA decreased significantly when the IFTA score increased (p<0.002). In the correlation analysis, the IFTA score was negatively correlated with SPEA (rs=−0.461, p<0.001), and positively correlated with proteinuria (rs=0.274, p=0.041).ConclusionThese findings suggest that increased collagen turnover decreases over time concerning the progression of renal fibrosis. Monitoring of SPEA level may useful as a biomarker for early determination of CKD progression and severity.

Abstract
Abstract
Introduction. Familial Mediterranean Fever (FMF) is an autoinflammatory disease. Prolidase is a specific imidodipeptidase that plays a role in collagen degradation, and an important role in inflammation and wound healing. Hypoxia-inducible factor-1α (HIF-1) is an important protein in the regulation of immunological response, hemostasis, vascularization. The aim of the study was to compare serum prolidase and HIF-1α levels in patients with FMF in attack-free period and healthy control group.
Methods. Between August 2017 and December 2017, sixty patients diagnosed with FMF according to the criteria of the Tel-hashomer and admitted to Sivas Cumhuriyet University Medical Faculty, Internal Medicine Rheumatology Department and sixty healthy volunteers were enrolled in the study.
Results. Median serum prolidase levels were 72.1 (25.1–114.9) ng/ml in FMF group and 30.7 (21.3–86.2) ng/mL in healthy control (HC) group (p = 0.018). ROC analysis showed that the sensitivity was 65% and the specificity was 68.3% at serum prolidase levels 54.03 ng/mL (p < 0.05). The median serum levels of HIF-1α in the FMF group was 482.0 (292.0–3967.0) pg/mL and 632.0 (362.0–927.0) pg/mL in the HC group (p > 0.05). There was no significant correlation between laboratory findings, sex, age, and prolidase (p > 0.05).
Conclusion. Serum prolidase enzyme levels in FMF patients with attack-free period were significantly higher than in the HC group. However, the role of prolidase and HIF1-α in the FMF disease needs to be clarified with more extensive and comprehensive studies.

Abstract
Background/aim Changes in collagen metabolism and fibroblastic activity may play a role in the pathogenesis of brucellosis. The prolidase enzyme plays an important role in collagen synthesis. We aimed to investigate the association of prolidase levels with brucellosis. Materials and methods Serum prolidase levels in 20 patients newly diagnosed with brucellosis were compared with levels in 30 healthy control subjects. Patients with brucellosis were reassessed 3 months later for prolidase, other laboratory measurements, and response to treatment. Results The levels of serum prolidase were significantly higher in brucellosis patients compared with those of healthy controls. Prolidase, sedimentation, and C-reactive protein levels were significantly lower after antibrucellosis treatment than before treatment. Conclusion The current study is the first to demonstrate significantly increased serum prolidase levels in patients with brucellosis compared with healthy controls. Prolidase levels also significantly decreased with antibrucellosis treatment. This finding provides a new experimental basis to understand the pathogenesis of brucellosis in relation to collagen metabolism. The increase in serum prolidase levels might be related to several factors such as tissue destruction, increased fibroblastic activity, and granuloma formation, all of which are involved in the natural history of brucellosis.

Abstract
Objective: To investigate serum prolidase activity and oxidative stress in patients with temporomandibular joint internal derangement (TMJ-ID).Methods: Seventy patients with Wilkes stage III, IV, and V joints and 70 healthy controls were included. Serum prolidase activity and oxidative stress parameters, including total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), advanced oxidation protein products (AOPP), glutathione (GSH), ferric reducing antioxidant power (FRAP), and lipid hydroperoxide (LOOH) were measured.Results: The levels of prolidase, TOS, OSI, AOPP, and LOOH were significantly higher in the TMJ-ID group than in the control (p = .0001). TAS and FRAP level was significantly lower in the TMJ-ID group than in the control (p = .0001). There was no significant difference in GSH between groups.Conclusion: Significantly increased prolidase activity and oxidative stress in patients with TMJ-ID may be related to long-term collagen tissue damage, and inflammation and can be effective in the etiology of TMJ-ID.

Abstract
Aim: Assessment of plasma prolidase levels in polycystic ovary syndrome (PCOS). Patients & methods: PCOS patients were screened according to Rotterdam Criterion and prolidase levels were measured. Results: A total of 170 patients and 160 controls were recruited for the study and it was found that prolidase levels were significantly higher in PCOS group (991.10 ± 39.52) than control (621.89 ± 23.94). Furthermore it has been found that prolidase levels increase with the number of cysts in ovaries. Conclusion: Significant difference between prolidase levels in PCOS and control shows that it may be used as a diagnostic marker for disease. In addition to this, there is a positive correlation found between prolidase levels and number of cysts, hence may be used as a prognostic marker to monitor disease status.
