    Background Pain has been frequently described as a clinical feature of COVID-19, and the main pain syndromes that have been associated with the acute phase of this disease so far are headache, myalgia, arthralgia, and neuropathic pain. Understanding the characteristics of pain symptoms is crucial for a better clinical approach. Methods Patients who were diagnosed as having COVID-19 using reverse transcription-polymerase chain reaction were included in the study. Patients were asked to complete a 51-item questionnaire via a phone interview, which included questions on demographics, acute COVID-19 symptoms, the presence of pain symptoms, and their characteristics in the acute phase of COVID-19. Results A total of 222 out of 266 patients with COVID-19 participated in the study, yielding a response rate of 83.5%. A total of 159 patients reported at least one kind of pain syndrome with a prevalence of 71.6%. Myalgia was reported in 110 (49.6%) patients, headache in 109 (49.1%), neuropathic pain symptoms in 55 (24.8%), and polyarthralgia in 30 (13.5%) patients. A total of 66 patients reported only one type of pain, 46 reported two types, 42 reported three types, and five patients reported all four types of pain. Logistic regression analysis showed that there were significant associations between these pain syndromes and a strong association was found between neuropathic pain and headache. Conclusion Pain is a frequently observed symptom of mild-to-moderate COVID-19. There are significant relationships between pain syndromes in COVID-19, which may be due to a sequence of common etiologic factors. Significance This study described the main pain syndromes associated acute phase of mild-to-moderate COVID-19 and its associated features. Headaches and pain of neuropathic characteristics were prevalent in this sample.

    Multiple sclerosis (MS) is an inflammatory, autoimmune demyelinating, and neurodegenerative disorder of the central nervous system. Interactions between environmental factors, predisposition genes, and determining genes appear to be involved in its etiology. Epigenetic mechanisms such as microRNA-mediated gene regulation can determine the susceptibility and severity of autoimmune diseases. Therefore, to determine the role of miR-146a and miR-155 in MS and its developmental stages, the expression levels in the serum of MS and clinically isolated syndrome (CIS) patients were compared with those of healthy controls. In the present study, the expression levels of miR-146a and miR-155 were assessed using quantitative Real-Time PCR in blood samples of 15 CIS patients and 61 relapsing-remitting multiple sclerosis (RRMS) patients alongside 32 healthy patients as controls. Furthermore, any associations with the clinicopathologic variables of the patients were also evaluated. Dysregulations were found only in the miR-146a and miR-155 expressions in the RRMS-Control group. When the RRMS patients were evaluated in terms of the characteristics of sex, annual attack rate, age of diagnosis, duration of follow-up, and immunomodulatory treatments used, no significant differences were observed. However, significant dysregulations were identified in miRNA expression in the vitamin D level, EDSS values, and the number of attacks. ROC curve analysis showed that miR-146a and miR-155 were significant in the RRMS-Control group for the area under the curve (AUC). It is possible that miR-146a may be associated with vitamin D deficiency and disease disability, while miR-155 may be associated with the number of attacks.

    Objective: A functional single nucleotide polymorphism, rs1611115, in the dopamine beta-hydroxylase (DBH) gene, is reported to regulate plasma enzyme activity levels. Mere, we report the first evaluation of this association in patients with early-onset Parkinson's disease (EOPD) and healthy controls in the Turkish population.Materials and Methods: We evaluated the DBH rs1611115 polymorphism in 114 (64 male and 50 female) Turkish patients with EOPD and 58 sex- and age-matched healthy controls from the Turkish population. A total of 27.2% (n=31) of our patients who had any variation including pathogenic or non-pathogenic missense, non-sense and/or intronic variation with unknown significance in EOPD genes were grouped as "variation-positive EOPD". A total of 50.8% (n=58) of our patients were grouped as "variation and family history-negative EOPD" and the possible contribution of the DBH rs1611115 polymorphism to EOPD pathogenesis was evaluated in this group.Results: There was no significant difference in the genotypic and allelic frequencies of DBH rs1611115 between patients with EOPD and controls. To our knowledge, this is the first evaluation of the DBH rs1611115 polymorphism in patients with EOPD and ethnically matched controls in the Turkish population.Conclusion: Some previous studies have reported conflicting association results between DBH rs1611115 polymorphism and PD pathogenesis in different ethnic groups. Therefore, further studies are needed to evaluate dopamine metabolism-related generic variants and to determine their possible roles in EOPD susceptibility in the Turkish population.

    In the present study, we focused on investigating the contribution of functional dopamine D2 and D3 receptor variants to motor and/or non-motor symptoms of early onset Parkinson's disease (EOPD). Three functional single nucleotide polymorphisms (SNPs), DRD3 rs6280, DRD2 rs2283265 and DRD2 rs1076560, were genotyped in 128 Turkish EOPD patients and then, statistical analysis was conducted for the potential impacts of SNPs on clinical parameters. All three SNPs were found to be statistically significant in terms of PD-related pain: DRD3 [rs6280; risk allele "T" for pain; p = 0.031; odds ratio (OR)=4.25], DRD2 [rs2283265; risk allele "A" for pain; p = 0.001; OR=8.47] and, DRD2 [rs1076560; risk allele "A" for pain; p = 0.022; OR=4.58]. Additionally, bilateral disease [p = 0.011; OR=5.10] and gender [risk group "female"; p = 0.003; OR=8.53] were also identified as significant univariate risk factors for PD-related pain. Based on logistic regression analysis conducted with the significant univariate risk factors, this the first report to clarify that a female patient with bilateral PD and DRD2 rs2283265 polymorphism has a significant risk for PD-related pain. Our findings might contribute to improve life quality by offering treatment options for pain in PD patients with these clinical and genetic features.
