As intact cognitive function in RA is essential for successfully performing day-to-day activities, adhering to treatment programs, understanding the biological and clinical factors which may affect cognition is important for improving clinical outcomes and quality of life.<a class="elsevierStyleCrossRef" href="#bib0175">5</a>Brain-derived neurotrophic factor (BDNF) stands out for its high level of expression in the brain and its potent effects on synapses. It is now widely accepted that the main function of BDNF in the adult brain is to regulate synapses, with structural and functional effects ranging from short-term to long-lasting, on excitatory or inhibitory synapses, in many brain regions. The diverse effects of BDNF on brain synapses stem from its complex downstream signaling cascades, as well as the diametrically opposing effects of the pro- and mature form through distinct receptors, tyrosine receptor kinase B(TrkB) and p75 neurotrophin receptor (NTR). Many aspects of BDNF cell biology are regulated by neuronal activity. The synergistic interactions between neuronal activity and synaptic plasticity by BDNF make it an ideal and essential regulator of cellular processes that underlie cognition and other complex behaviors.<a class="elsevierStyleCrossRef" href="#bib0180">6</a>The aim of the present study was to assess the use of BDNF as a potential biomarker of cognitive dysfunction in Egyptian rheumatoid patients with and without activity and evaluate its relation to depression. Find a relation between cognitive dysfunction, depression, and BDNF serum levels in rheumatoid arthritis patients.Patients and methodsThe study was carried out on 60 adult RA patients recruited from Internal Medicine Department and outpatient's clinic of Kasr Al Aini University Hospitals fulfilling European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) 2010 criteria.<a class="elsevierStyleCrossRef" href="#bib0185">7</a> The patients were subdivided in to two groups, group A included 30 patients with active RA and group B included 30 patients with inactive RA. Patients were further classified into having fibromyalgia or not according to the 2010 American College of Rheumatology Preliminary Diagnostic Criteria for Fibromyalgia (ACR 2010).<a class="elsevierStyleCrossRef" href="#bib0190">8</a> Patients with other autoimmune disease, diabetes, hypertension, coronary artery disease, cerebrovascular disease, dyslipidemia, thyroid disease, history of head trauma with loss of alertness, established neurological damage, drug abuse, dependence, or underlying psychiatric illness and those smoking were excluded from this work. Thirty apparently healthy volunteers with no history of autoimmune diseases were included as a control group. The participants provide their written informed consent to participate in this study. The study was approved by the Research Ethical committee of Cairo University (code MD-141-2021).All patients were subjected to full history taking, complete medical examination, assessment of RA disease activity by disease activity score 28 (DAS28),<a class="elsevierStyleCrossRef" href="#bib0195">9</a> Assessment of cognitive function was via The Montreal Cognitive Assessment (MoCA) test<a class="elsevierStyleCrossRef" href="#bib0200">10</a> and assessment of depression using the Patient Health Questionnaire-9 (PHQ-9).<a class="elsevierStyleCrossRef" href="#bib0205">11</a> Complete blood count (CBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), serum level of creatinine, blood urea, uric acid, urine analysis, alanine transaminase (ALT), aspartate aminotransferase (AST), lipid profile (total cholesterol, low-density lipoprotein LDL-C, high-density lipoprotein HDL-C, Serum triglycerides TG), rheumatoid factor (RF), Anti-Cyclic Citrullinated Peptide (Anti-CCP) antibody, anti-nuclear antibody (ANA) and serum BDNF levels were measured.Human BDNF ELISA kit (Catalog No. E1302Hu) was based on double antibody sandwich enzyme-linked immune-sorbent assay (ELISA) technology. The plate has been pre-coated with Human BDNF antibody. BDNF present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Human BDNF antibody is added and binds to BDNF in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated BDNF antibody. After incubation unbound Streptavidin-HRP is washed away during a washing step. Substrate solution is then added, and color develops in proportion to the amount of Human BDNF. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450nm. The optical density (OD) measured spectrophotometrically at wavelength 450±2nm is proportional to the concentration of BDNF. The BDNF concentration was calculated by comparing the sample OD to the standard curve.Statistical analysisData were coded and entered using the statistical package for the Social Sciences (SPSS) version 28 (IBM Corp., Armonk, NY, USA). Data was summarized using mean, standard deviation, median, minimum, and maximum for quantitative variables and frequencies (number of cases) and relative frequencies (percentages) for categorical variables. Comparisons between groups were done using unpaired t test when comparing two groups and analysis of variance (ANOVA) with multiple comparisons post hoc test when comparing more than two groups in normally distributed quantitative variables while non-parametric Kruskal–Wallis test and Mann–Whitney test were used for non-normally distributed quantitative variables.<a class="elsevierStyleCrossRef" href="#bib0305">12</a> For comparing categorical data, Chi square (χ2) test was performed.

Learning and long-term potentiation processes in the hippocampus require BDNF and its receptor, tyrosine receptor kinase B (TrkB).<a class="elsevierStyleCrossRef" href="#bib0220">16</a>BDNF is a major member in the neurotrophin, plays a critical role not only in neurodevelopment and neuroprotection but also in synaptic plasticity, learning, and a variety of cognitive functions. Substantial evidence in animal studies showed that the up regulation of BDNF signaling pathway or endogenous BDNF levels promoted neural development and memory capability, while inhibition of BDNF signaling interfered with learning and long-term memory formation.<a class="elsevierStyleCrossRef" href="#bib0225">17</a>We aimed in our study to find a relationship between BDNF and cognitive impairment in patients with RA and explore the possibility of using BDNF as a biomarker for this condition.In the current study, the mean age in group A was 37.8 (±9.37), and the mean age in group B was 39.97 (±8.04). The duration of disease in group A was 56.00 months (±63.29), while the mean duration in group B was 31.3 months (±32.60).Imran et al., who studied the level of depression in RA and its relationship with disease severity, enrolled patients with a mean age of 43.5±11.9 years, and the mean duration of disease was 7.8±5.5 years.<a class="elsevierStyleCrossRef" href="#bib0230">18</a> While Szlachetka et al., who studied the determinants of cognitive function in RA, involved patients with a mean age of 73.7 years with RA duration of 31.3 years.<a class="elsevierStyleCrossRef" href="#bib0235">19</a>In the current study, the median RA duration in patients with normal cognitive function was 16 months, ranging from 1 month to 180 months, while the median RA duration in impaired cognitive function patients was 24 months, ranging from 1 to 204 months. There was no statistically significant difference in the mean duration of disease between the two groups, we did not find a statistically significant correlation between RA duration and the level of cognitive dysfunction (r=−0.149, p=0.257).In accordance with our study, Appenzeller et al., found no significant relation between the duration of the illness and cognitive impairment.<a class="elsevierStyleCrossRef" href="#bib0315">20</a>In our study, we described cognitive dysfunction in patients with RA as compared to the control group (p=0.001) and compared it in active and inactive groups, showing that 66.7% of active RA patients had abnormal cognitive function and the same percentage in inactive patients.

Eighty percent of patients had moderate to severe depression.Pezzato et al. found the prevalence of depression to be 14.3% among patients with RA. Out of the 70 depressed patients, 30 subjects, already known to be depressed in the past, were still depressed at the time of the assessment, with only 11 (15.7%) on antidepressants. Their multivariate analysis showed that male sex, a higher patient global assessment (PGA) score, the use of antidepressants, and a higher health assessment questionnaire (HAQ) score were significantly associated with an increased risk of depression.<a class="elsevierStyleCrossRef" href="#bib0325">30</a>Dickens et al. found twelve independent studies comparing depression in patients with rheumatoid arthritis with depression in healthy control subjects.

Patients and methodsThe study was carried out on 60 RA patients; 30 were active (group A) and 30 were non active (group B); and 30 controls (group C). RA disease activity was assessed via DAS28 tool, cognitive function via The Montreal Cognitive Assessment and depression via the PHQ depression scale. Serum BDNF levels were measured. ResultsThe mean age in group A was 37.8 (±9.37) years with 83.3% females, in group B was 39.97 (±8.04) years with 86.7% females and in group C was 33.17 (±3.6) years with 93.3% females. Abnormal cognitive functions test was detected in 66.7% of group A, 66.7% of group B, and in 23.3% of group C. There was a statistically significant difference in BDNF serum level between both groups of patients (1.58±0.9ng/ml for group A, 1.81±1.17ng/ml for group B) compared with the control group (3.01±1.25ng/ml, p<0.001).There was no statistically significant difference between BDNF and both disease duration and cognitive function, also no statistically significant difference regarding cognitive function, depression, and BNDF levels in patients with and without fibromyalgia.
