Item Successful Treatment of a Child with Hemoglobin Hammersmith with Hematopoietic Stem Cell TransplantationYildirim, AT; Gülen, H; Türkmen, H; Özek, G; Oymak, Y; Durmaz, B; Karaca, EHemoglobin (Hb) Hammersmith, formed by serine substitution for phenylalanine at residue 42 in the beta-globin chain, is a very rare variant of unstable hemoglobin with low oxygen affinity. For patients with hemoglobinopathies, it is well-established that hematopoietic stem cell transplantation provides a complete cure, but the literature on its role for those with Hb Hammersmith is limited. A seven-month-old girl who was examined for anemia and splenomegaly was followed up for congenital hemolytic anemia. The patient with visible cyanosis of the lips and whose p50 was low in blood gas was diagnosed with Hb Hammersmith through the DNA sequence analysis. During the follow-up, frequent blood transfusions had to be given due to anemia aggravated by infections. Following a successful hematopoietic stem cell transplant from an HLA-matched sibling, the patient completely recovered from Hb Hammersmith. The case is presented because of its rarity.Item ACTN3 R577X Polymorphism Does Not Influence Explosive Leg Muscle Power in Elite Turkish Volleyball PlayersErgin, E; Dinc, N; Yücel, SB; Taneli, F; Durmaz, BThe aim of the present study was to evaluate the relationship between explosive power and ACTN3 R577X polymorphism among elite women volleyball players. Voluntary participants (20.88 +/- 3.20 years, 172.72 +/- 9.34 cm, 61.79 +/- 10.08 kg, 20.70 +/- 2.21 kg/m(2)) including elite Turkish women volleyball players (n=72) and nonathletic university students (n=99) were included in the study. Venous blood samples were collected before the jump tests. After anthropometric measurements were obtained, subjects performed static vertical jump and counter movement jump to evalute explosive power performances. ACTN3 R577X polymorphism analyses were assessed on the blood samples in order to evaluate the genotypic frequencies of the ACTN3 R577X genotypes differed between groups. There was no statistically significant difference on ACTN3 R577X polymorphism groups' genotype distribution in the study groups. The genotype distribution was similar for both volleyball players and the nonathletic university students (p= 0.77). Moreover, there was no statistically significant difference for vertical and counter jump results on ACTN3 R577X polymorphism RR, RX and XX genotypes for volleyball players and the nonathletic university students. As a conclusion, the findings of the study reveal that ACTN3 R577X polymorphism has a key role in explaining individual phenotypic differences in muscle strength, but not affecting volleyball performance singly at least for elite Turkish women volleyball players. In addition, it is believed that this polymorphism are not strong enough to be predictive or/and utilized seperately as a talent identification factor in volleyball.Item Does MCT1-T1470A Polymorphism Modify Lactate Kinetics and Training Status?Turgay, F; Bilgin, Z; Yigittürk, O; Durmaz, B; Asikovali, S; Köksala, AStudy Objectives: The (MCT1-T1470A) polymorphism related to monocarboxylate transporters 1 (MCTs) which transport lactate (LA) may affect LA kinetics and training status, which is unclear. Methods: Participants in the athletic group (AG; 42 anaerobic athletes; 21.8 +/- 2.7 years) and the control group (CG; 39 sedentary men; 23.0 +/- 3.3 years) performed the Yoyo recovery level 1 test. LA elimination speeds were calculated by dividing the difference between LA5, LA15, and LA30 values of passive recovery corresponding to the 5th, 15th, and 30th minutes following the Yoyo test by the elapsed time. MCT1 polymorphism was determined from genomic DNA samples by next-generation sequencing. Results:The LA5, LA15, and LA30 values of the control group were significantly higher than those of the athlete group (p=0.053, p=0.042, and p=0.028, respectively), but not for LA elimination speeds. There was no significant difference for these parameters between genotype groups. Although the VO2max of the AA control group was significantly greater than that of the T carrier ( Tc) control group, there was no significant difference for VO2max between the athletic genotype groups (AA and Tc). Conclusions: MCT1-T1470A polymorphism did not have a significant effect on LA kinetics in athletes. However, the AA group was negatively affected for VO2max compared to the Tc group. This may be due to extreme sensitivity of the AA group to the training caused by this polymorphism. Further studies are needed to shed light on this entity.Item THE RELATIONSHIP BETWEEN MRI FINDINGS, PAIN AND DISABILITY IN THE PATIENTS WITH CERVICAL OSTEOARTHRITISAltan, L; Ökmen, BM; Tuncer, T; Akarirmak, U; Ayhan, F; Bal, A; Bozbas, G; Cerrahoglu, L; Cevik, R; Durmaz, B; Duruöz, T; Dülgeroglu, D; Gürer, G; Gürsoy, S; Hepgüler, S; Hizmetli, S; Kaçar, C; Kaptanoglu, E; Kocabas, H; Nas, K; Nur, H; Özçakir, S; Özdolap, S; Sindel, D; Sahin, O; Sendur, F; Tikiz, C; Ugurlu, HItem THE FREQUENCY AND ASSOCIATION OF KNEE, HIP, HAND AND SPINE OSTEOARTHRITIS IN TURKISH POPULATION: A PRELIMINARY RE PORT OF MULTICENTER LONGITUDINAL STUDYTuncer, T; Ugur, S; Nur, H; Kacar, C; Akarimak, U; Altan, L; Ayhan, F; Bal, A; Basaran, S; Bilgilisoy, M; Bozbas, G; Cerrahoglu, L; Cevik, R; Coskun, N; Dagli, Z; Durmaz, B; Duruoz, T; Dulgeroglu, D; Gurer, G; Gursoy, S; Hepguler, S; Hizmetli, S; Kaplanoglu, E; Kaya, T; Kocabas, H; Kuran, B; Melikoglu, M; Nas, K; Oncu, J; Ozcakir, S; Ozdolap, S; Saridogan, M; Sarikaya, S; Sindel, D; Sahin, O; Sendur, OF; Tikiz, C; Ugurlu, H; Yilmaz, FItem 2017 update of the Turkish League Against Rheumatism (TLAR) evidence-based recommendations for the management of knee osteoarthritisTuncer, T; Cay, FH; Altan, L; Gurer, G; Kacar, C; Ozcakir, S; Atik, S; Ayhan, F; Durmaz, B; Eskiyurt, N; Genc, H; GokceKutsal, Y; Gunaydin, R; Hepguler, S; Hizmetli, S; Kaya, T; Kurtais, Y; Saridogan, M; Sindel, D; Sutbeyaz, S; Sendur, OF; Ugurlu, H; Unlu, ZIn a Turkish League Against Rheumatism (TLAR) project, evidence-based recommendations for the management of knee osteoarthritis (OA) was developed for the first time in our country in 2012 (TLAR-2012). In accordance with developing medical knowledge and scientific evidence, recommendations were updated. The committee was composed of 22 physical medicine and rehabilitation specialists (4 have rheumatology subspeciality also) and an orthopaedic surgeon. Systematic literature search were applied on Pubmed, Embase, Cochrane and Turkish Medical Index for the dates between January the 1st 2012 and January the 29th of 2015. The articles were assessed for quality and classified according to hierarchy for the level of evidence, and the selected ones sent to committee members electronically. They were asked to develop new recommendations. In the meeting in 2015, the format of the recommendations was decided to be patient-based and considering the grade and the severity of the disease. By the discussion of the each item under the light of new evidences, the final recommendations were developed. Each item was voted electronically on a 10-cm visual analogue scale (VAS) and the strength of recommendation (SoR) was calculated. In the light of evidences, totally 11 titles of recommendations were developed; the first 7 were applicable to each patient in every stages of the disease, remaining were for defined specific clinical situations. The mean SoR value of the recommendations was between 7.44 and 9.93. TLAR-2012 recommendations were updated in a new format. We think that, present recommendations will be beneficial for the physicians who manage, as well as the patients who suffer from the disease.Item Translation and validation of the Turkish version of the Ankylosing Spondylitis Quality of Life (ASQOL) questionnaireDuruöz, MT; Doward, L; Turan, Y; Cerrahoglu, L; Yurtkuran, M; Calis, M; Tas, N; Ozgocmen, S; Yoleri, O; Durmaz, B; Oncel, S; Tuncer, T; Sendur, O; Birtane, M; Tuzun, F; Bingol, U; Kirnap, M; Erturk, GC; Ardicoglu, O; Memis, A; Atamaz, F; Kizil, R; Kacar, C; Gurer, G; Uzunca, K; Sari, HThe Ankylosing Spondylitis Quality of Life (ASQoL) questionnaire is a disease-specific measure of needs-based quality of life developed in the UK and the Netherlands. This study describes translation, validation, and reliability of the scale into Turkish population. The ASQoL was translated into Turkish using the dual-panel process. Content validity was assessed via cognitive debriefing interviews with ankylosing spondylitis (AS) patients. Patients with AS according to modified New York criteria were recruited into the study from 12 hospitals of all part of Turkey. Psychometric and scaling properties were assessed via a two administration survey involving the ASQoL, the Nottingham Health Profile (NHP), Bath AS Functional Index (BASFI), and Bath AS Disease Activity Index (BASDAI). Classical psychometrics assessed reliability, convergent validity (correlation of ASQoL with NHP, BASFI, and BASDAI) and discriminative validity (correlation of ASQoL with perceived AS-severity and general health). Cognitive debriefing showed the new Turkish ASQoL to be clear, relevant, and comprehensive. Completed survey questionnaires were received from 277 AS patients (80 % Male, mean age 42.2/SD 11.6, mean AS duration 9.4 years/SD 9.4). Test-retest reliability was excellent (0.96), indicating low random measurement error for the scale. Correlations of ASQoL with NHP sections were low to moderate (NHP Sleep 0.34; NHP Emotional Reactions 0.83) suggesting the measures assess related but distinct constructs. The measure was able to discriminate between patients based on their perceived disease severity (p < 0.0001) and self-reported general health (p < 0.0001). The Turkish version of ASQoL has good reliability and validity properties. It is practical and useful scale to assess the quality of life in AS patients in Turkish population.Item Correlation of clinical signs and magnetic resonance imaging findings in patients with lumbar spondylosisAltan, L; Ökmen, BM; Tuncer, T; Sindel, D; Çay, HF; Hepgüler, S; Sarikaya, S; Ayhan, F; Bal, A; Bilgilisoy, M; Çapkin, E; Cerrahoglu, L; Çevik, R; Dülgeroglu, D; Durmaz, B; Duruöz, T; Gürer, G; Gürsoy, S; Hizmetli, S; Kaçar, C; Kaptanoglu, E; Ecesoy, H; Melikoglu, M; Nas, K; Nur, H; Özcakir, S; Sahin, N; Sahin, O; Saridogan, M; Sendur, ÖF; Sezer, I; Bozbas, GT; Tikiz, C; Ugurlu, HObjectives: The purpose of the study was to contribute further to this debated topic by investigating the correlation of magnetic resonance imaging (MRI) findings with the clinical picture in lumbar spondylosis patients.Patients and methods: This multicenter retrospective study (as part of the epidemiological project of the TLAR-OASG [Turkish League Against Rheumatism-Osteoarthritis Study Group]) included 514 patients (101 males, 413 females; mean age: 63.6 +/- 10.8 years; range, 40 to 85 years) who were diagnosed as lumbar spondylosis by clinical examination and direct X-ray between December 2016 and June 2018. Demographic characteristics of patients, Visual Analog Scale for pain, presence of radiating pain, Roland-Morris disability questionnaire, straight leg raise test, deep tendon reflexes, neurogenic intermittent claudication symptoms, any decrease of muscle strength, and abnormality of sensation were recorded. Lumbar MRI findings of the patients were recorded as positive or negative in terms of disc herniation, intervertebral disc degeneration, root compression, osteophytes, spinal stenosis. Statistical analysis was done to assess the correlation between the clinical symptoms, physical examination, and MRI findings.Results: Correlation analysis of the MRI results and the clinical findings showed a significant correlation between straight leg raise test and root compression (p<0.001, r=0.328) and a significant correlation between neurogenic intermittent claudication and spinal stenosis (p<0.001, r=0.376). Roland-Morris disability questionnaire had a significant correlation with all MRI findings (p<0.05, r<0.200). Conclusion: The results of this study corroborate the notion that diligent patient history and physical examination are more valuable than MRI findings, even though a higher incidence of abnormal MRI findings have been obtained in patients with disability and dermatomal radiating pain.Item Evidence-Based Recommendations for the Management of Knee Osteoarthritis: A Consensus Report of the Turkish League Against RheumatismTuncer, T; Çay, HF; Kaçar, C; Altan, L; Atik, OS; Aydin, AT; Ayhan, FF; Yanik, BÇ; Durmaz, B; Eskiyurt, N; Genç, H; Kutsal, YG; Günaydin, R; Hepgüler, S; Hizmetli, S; Kaya, T; Kurtais, Y; Ölmez, N; Saridogan, M; Sindel, D; Tur, BS; Sütbeyaz, S; Sendur, ÖF; Ugurlu, H; Ünlü, ZObjectives: Knee osteoarthritis (OA) is a common disease which causes pain, disability and great socioeconomic burden as a result. Turkish League Against Rheumatism (TLAR) initiated a project to prepare national, evidence-based recommendations for the management of knee osteoarthritis supported by expert-opinion in order to assist the physicians who are interested in knee OA in their daily clinical practice. Materials and methods: The expert committee was composed of 25 academicians, 23 of whom were physical medicine and rehabilitation (PM&R) specialists (three also had rheumatology subspeciality) and two were orthopedic surgeons. At the first meeting, the previous guidelines were discussed, and 2008 Osteoarthritis Research Society International (OARSI) recommendations were decided to be taken as the fundamental template for national recommendations. Databases of the Pubmed, Embase, Cochrane, and Turkish Medical Index were used to search the literature, and this was carried out for the period between 2009-2010 for international publications since studies up to 2009 were present in the 2010 OARSI update. No limit was applied for searching of national publications. The selected relevant publications were graded according to evidence level and quality, and were sent to the members who were then asked to suggest propositions according to their experiences, knowledge, and review of the literature. After amalgamation and editing of new proposals, Delphi rounds were started. After five Delphi rounds, the propositions on which the members were in consensus, were discussed with regard to evidence and the strength of recommendation was determined by measuring on visual analog scale (VAS) for each proposal at the final meeting. Results: Nineteen propositions (one for general principles, nine for non-pharmacologic treatments, seven for pharmacologic treatments, and two for surgical treatments) were accepted as the TLAR Evidence-Based Recommendations for the Management of Knee OA in consensus as a result of Delphi rounds. Conclusion: Evidence-based recommendations for the management of knee OA were developed by TLAR for the first time in our country. The recommendations should be updated regularly according to new evidence and insights. It is expected that physicians who are interested in knee OA will benefit greatly from this report in their daily clinical practice.Item The clinical, functional, and radiological features of hand osteoarthritis: TLAR-osteoarthritis multi-center cohort studyDuruöz, MT; Gürsoy, DE; Tuncer, T; Altan, L; Ayhan, F; Bal, A; Bilgilisoy, M; Cerrahoglu, L; Çapkin, E; Çay, HF; Çevik, R; Durmaz, B; Dülgeroglu, D; Gürer, G; Gürsoy, S; Hepgüler, S; Hizmetli, S; Kaçar, C; Kaptanoglu, E; Kaya, T; Ecesoy, H; Melikoglu, MA; Nas, K; Nur, H; Özçakir, S; Saridogan, M; Sarikaya, S; Sezer, I; Sindel, D; Sahin, N; Sahin, Ö; Sendur, ÖF; Bozbas, GT; Tikiz, C; Ugurlu, HObjectives: This study aims to evaluate the clinical, functional, and radiological features of hand osteoarthritis (OA) and to examine their relationships in different geographic samples of the Turkish population. Patients and methods: Between April 2017 and January 2019, a total of 520 patients (49 males, 471 females; mean age: 63.6 +/- 9.8 years) with hand OA were included in the study from 26 centers across Turkiye by the Turkish League Against Rheumatism (TLAR). The demographic characteristics, grip strengths with Jamar dynamometer, duration of hand pain (month), the severity of hand pain (Visual Analog Scale [ VAS]), and morning stiffness were evaluated. The functional disability was evaluated with Duruoz Hand Index (DHI). The Kellgren-Lawrence (KL) OA scoring system was used to assess the radiological stage of hand OA. Results: The DHI had significant correlations with VAS- pain (r= 0.367, p<0.001), duration of pain (r=0.143, p=0.001) and bilateral handgrip strengths (r=-0.228, p=0.001; r=-0.303, p<0.001). Although DHI scores were similar between the groups in terms of the presence of hand deformity (p= 0.125) or Heberden's nodes (p=0.640), the mean DHI scores were significantly higher in patients with Bouchard's nodes (p=0.015). The total number of nodes had no significant correlations with the VAS-pain and DHI score (p>0.05). The differences between the groups of radiological hand OA grades in terms of age (p= 0.007), VAS-pain (p<0.001), duration of pain (p<0.001), and DHI (p<0.001) were significant. There were no significant differences between radiological hand OA grades according to the duration of the stiffness, grip strength, and BMI (p>0.05 for all). Conclusion: In our population, the patients with hand OA had pain, functional disability, and weak grip strength. The functional impairment was significantly correlated with the severity of the pain, and the functional status was worse in high radiological hand OA grades.Item Prevalence of Rheumatoid Arthritis and Spondyloarthritis in Turkey: A Nationwide StudyTuncer, T; Gilgil, E; Kaçar, C; Kurtais, Y; Kutlay, S; Bütün, B; Yalçin, P; Akarirmak, Ü; Altan, L; Ardiç, F; Ardiçoglu, Ö; Altay, Z; Cantürk, F; Cerrahoglu, L; Çevik, R; Demir, H; Durmaz, B; Dursun, N; Duruöz, T; Erdogan, C; Evcik, D; Gürsoy, S; Hizmetli, S; Kaptanoglu, E; Kayhan, Ö; Kirnap, M; Kokino, S; Kozanoglu, E; Kuran, B; Nas, K; Öncel, S; Sindel, D; Orkun, S; Sarpel, T; Savas, S; Sendur, OF; Senel, K; Ugurlu, H; Uzunca, K; Tekeoglu, I; Guillemin, FObjectives: This study aims to estimate the prevalence of rheumatoid arthritis (RA) and spondyloarthritis (SpA) in Turkey using the same telephone questionnaire developed for screening RA and SpA in France and used in Serbia and Lithuania. Material and methods: The study was performed in two steps. In step I, the French questionnaire was translated into Turkish and validated through a group of 200 patients (80 males, 120 females; mean age 44.0 +/- 13.1 years; range, 19 to 75 years) followed up at the rheumatology departments of University Hospitals in Antalya and Ankara. In step II, the validated Turkish questionnaire was administered face-to-face to randomly selected 4,012 subjects (1,670 males, 2,342 females; mean age 41.5 +/- 16.8 years; range, 16 to 97 years) by trained general practitioners across the country, in 25 provinces for case detection. The subjects who were suspected of having RA or SpA in accordance with the questionnaire were invited to the nearest university hospital for rheumatologic examination in order to confirm the diagnosis. Results: In step II, a total of 25 subjects (2 males, 23 females) were diagnosed as RA. The standardized RA prevalence for the general population of Turkey was calculated as 0.56% (95% confidence interval [CI]; 0.33-0.79), 0.10% (95% CI; -0.05-0.25) for males and 0.89% (95% CI; 0.51-1.27) for females. A total of 18 subjects (3 males, 15 females) were diagnosed as SpA. The standardized SpA prevalence for the general population of Turkey was 0.46% (95% CI; 0.25-0.67), 0.17% (95% CI; -0.03-0.37) for males and 0.65% (95% CI; 0.32-0.98) for females. The prevalence of RA was highest in the Northern region (2.00%) and the prevalence of SpA was highest in the Central region (1.49%). Conclusion: The prevalences of RA and SpA in Turkey are close to each other and there are significant inter-regional variations in prevalences of both RA and SpA.
