Clinical characteristics of patients with connective tissue disease-related interstitial lung disease: a retrospective analysis

INTRODUCTION

Interstitial lung disease is one of the most critical manifestations of connective tissue diseases that may cause morbidity and mortality. This study aimed to evaluate the clinical and demographic characteristics and treatment of the patients with connective tissue disease-related interstitial lung disease.

METHOD

This retrospective observational study included patients from the Gulhane Rheumatology Interstitial Lung Disease cohort between October 2016 and June 2023. The patients were assessed retrospectively.

RESULTS

A total of 173 patients were included in the study with a mean age of 63.4 ± 11.9 years. The frequencies of CTD were 34.1% Sjogren's syndrome, 30.1% rheumatoid arthritis, 25.4% systemic sclerosis, 5.8% undifferentiated connective tissue disease, 2.9% idiopathic inflammatory myositis, 1.2% mixt connective tissue disease, and 0.6% systemic lupus erythematosus in decreasing frequencies. Nonspecific interstitial pneumonia, which was the most common interstitial lung disease pattern in 103 (59.5%) patients, was most frequent among patients with SS and SSc (p < 0.001 vs. p < 0.001). Usual interstitial pneumonia was most frequent among patients with RA (p < 0.001). All patients received immunosuppressive treatment, most commonly azathioprine. 57.2% were using immunosuppressives for ILD. Six patients had mortality, and infections were the leading cause.

CONCLUSIONS

As a critical manifestation of connective tissue diseases, immunosuppressive treatment is indispensable in the management of interstitial lung diseases especially those at an increased risk for progression. The treatment approaches should be assessed in a patient-based way. The patients under immunosuppressive treatment should be cautiously followed for infections. Key Points • Interstitial lung disease is a noteworthy manifestation of connective tissue diseases. • The clinical findings, treatment requirements, and progression vary according to the severity of the disease. • Immunosuppressive treatment may be essential in patients with worsening symptoms, impaired pulmonary function tests, and radiological findings.

The Association between SLAP Lesions and Critical Shoulder Angle and Glenoid Depth

PURPOSE OF THE STUDY

The critical shoulder angle (CSA) is formed by the combination of glenoid inclination and acromial index and has been shown related to rotator cuff tears and glenohumeral osteoarthritis. SLAP lesions today have an important place among bicipitolabral pathologies that cause intensive shoulder pain. We aimed to investigate the relationship between CSA and glenoid depth and SLAP lesions.

MATERIAL AND METHODS

Between March 2017 and January 2022, 279 consecutive shoulder arthroscopy patients' MRI images were retrospectively examined. After the exclusion criteria, 191 patients were eligible. Patients with SLAP lesions (n=37) were assembled as the study group (Group 1), and patients with intact superior labrum (n=154) were named as the control group (Group 2). Critical shoulder angle (CSA) and glenoid depth measurements were performed using the preoperative MRI images.

RESULTS

A total of 191 patients, of whom 84 were male (44%) were included. The mean age was 49.9±14.96 (range 18-79). There was a statistically signifi cant difference between the SLAP group (Group 1) and the control group (Group 2) in terms of CSA (p=0.032). The mean CSA was 31.66°±3.51° in Group 1 and 33.57° ±5.01° in Group 2. The cut-off value for CSA in patients with SLAP lesions was calculated as 32.85° and the area under the curve was 0.61, therefore a satisfactory association was observed between the groups. The mean glenoid depth was 4.32 ±1.25 mm in Group 1, and 4.39 ±0.32 mm in Group 2. There was no statistically signifi cant difference between the groups in terms of glenoid depth (p=0.136) and also no association between the glenoid depth and SLAP lesions was observed (cut-off=4.45 mm, AUC=0.32).

CONCLUSIONS

Low CSA is associated with SLAP lesions, just as in glenohumeral osteoarthritis. Further prospective clinical studies are needed to enlighten the predisposing effect of CSA to SLAP lesions and the success of superior labral repairs.

The relationship between Salusin-α, Salusin-β, and Klotho levels with subclinical atherosclerosis in ankylosing spondylitis

OBJECTIVE

Subclinical atherosclerosis (SA) is often observed in ankylosing spondylitis (AS) patients; Salusin-α (Sal-α), Salusin-β (Sal-β), and Klotho hormones are thought to be associated with atherosclerosis. This study aims to evaluate the relationship between Sal-α, Sal-β, and Klotho levels with SA in AS.

PATIENTS AND METHODS

The study included patients older than 18 years who applied between August 1, 2019, and September 1, 2019. Patients with AS were included in the AS group, and patients without a known disease were included in the healthy group. Epicardial adipose tissue thickness (EATT) and carotid intima-media thickness (CIMT) measurements were used to assess SA.

RESULTS

The study group included 38 (40.9%) patients diagnosed with AS, and the control group included 55 (59.1%) participants. CIMT and EATT levels were higher in the AS group than in the healthy group [0.37 (0.17) vs. 0.54±0.18, p<0.001; 0.44±0.11 vs. 0.54 (0.18), p=0.004, respectively]. There was no significant difference in Sal-α, Sal-β, and Klotho levels between the AS and healthy groups (p>0.05). Furthermore, there was no observed relationship between EATT or CIMT and Klotho, Sal-α, or Sal-β in either group (p>0.05).

CONCLUSIONS

Although SA level was higher in AS patients, there was no relationship between SA and Sal-α, Sal-β, and Klotho levels.

Does decision tree analysis predict oral ulcer activity-related factors in patients with Behçet's syndrome?

OBJECTIVES

The study aimed to identify the interactions among treatment protocols and oral ulcer activity related factors in patients with Behçet's syndrome (BS) using the Classification and Regression Tree (CART) algorithm.

METHODS

In this cross-sectional study, 979 patients with BS were included from16 centres in Turkey, Jordan, Brazil and the United Kingdom. In the CART algorithm, activities of oral ulcer (active vs. inactive), genital ulcer (active vs. inactive), cutaneous involvement (active vs. inactive), musculoskeletal involvement (active vs. inactive), gender (male vs. female), disease severity (mucocutaneous and musculoskeletal involvement vs. major organ involvement), smoking habits (current smoker vs. non-smoker), tooth brushing habits (irregular vs. regular), were input variables. The treatment protocols regarding immunosuppressive (IS) or non-IS medications were the target variable used to split from parent nodes to purer child nodes in the study.

RESULTS

In mucocutaneous and musculoskeletal involvement (n=538), the ratio of IS use was higher in patients with irregular toothbrushing (ITB) habits (27.1%) than in patients with regular toothbrushing (RTB) habits (14.2%) in oral ulcer activity. In major organ involvement (n=441), male patients with ITB habits were more likely treated with IS medications compared to those with RTB habits (91.6% vs. 77.6%, respectively).

CONCLUSIONS

Male BS patients on IS who have major organ involvement and oral ulcer activity with mucocutaneous and musculoskeletal involvement have irregular toothbrushing habits. Improved oral hygiene practices should be considered to be an integral part for implementing patient empowerment strategies for BS.

Epidemiological trends and seasonal dynamics of tuberculosis in Southeastern Turkey

Background

Tuberculosis (TB) is an important public health issue. Determining TB trend and seasonal variability provides useful information for designing treatment strategies and control programs.

Aim

The present study attempts to investigate the epidemiological trend and the seasonal variations.

Materials and Methods

TB data containing 2450 cases were collected over a period of seven years in the province of Diyarbakir in southeast Turkey. Trend function and seasonal variability were investigated by statistical curve fitting, surface fitting, and autoregressive time series analysis.

Results

The study revealed a gradually decreasing trend in the number of TB cases over a period of seven years. Total TB incidence had seasonal variations (P = 0.04); there was a greater number of TB cases between April and July, with a peak in June. There were significant monthly seasonal variations with June peaks among females (P < 0.001), in patients in the age groups of 0-15 (P < 0.001) and 36-45 years (P < 0.001), in new cases (P < 0.001) and in the patients with pulmonary TB (P = 0.01). The extra-pulmonary TB cases peak in May (P = 0.01). Pulmonary TB and TB patients in the 36-45 age group had summer peak, while the other groups peaked at spring.

Conclusions

Spring and summer peaks detected in total TB cases and in many subgroups indicate that multicenter and comprehensive clinical studies are needed to explain these variations.

Management of wet ascitic type of peritoneal tuberculosis: single center experience

OBJECTIVE

We aimed to present our experience with the management of 17 patients with ascites who underwent diagnostic laparoscopy or laparotomy, and histologic confirmation of wet ascitic type of peritoneal tuberculosis (TB).

PATIENTS AND METHODS

Between January 2008 and March 2019, 17 patients whose ascites were investigated by a gastroenterologist and who were thought to have non-cirrhotic ascites were referred to our Surgery clinic for peritoneal biopsy. The clinical, biochemical, radiological, microbiological, and histopathological data of the patients who underwent diagnostic laparoscopy or laparotomy were analyzed retrospectively. Histopathological examination of peritoneal tissue samples in hematoxylin-eosin-stained preparations revealed necrotizing granulomatous inflammation with caseous necrosis and Langhans type giant cells. Ehrlich-Ziehl-Neelsen (EZN) staining was studied with the suspicion of TB. Acid-fast bacilli (AFB) were detected in EZN stained slide. Histopathological findings were also considered.

RESULTS

Seventeen patients aged 18 to 64 years were included in this study. The most common symptoms were ascites and abdominal distention, weight loss, night sweats, fever and diarrhea. Radiological examination revealed peritoneal thickening, ascites, omental cacking, and diffuse lymphadenopathy. Histopathologically, necrotizing granulomatous peritonitis consistent with peritoneal TB were detected. While direct laparoscopy was preferred in sixteen patients, laparotomy was preferred in the remaining one due to previous surgical procedures.  However, seven were converted to open laparotomy.

CONCLUSIONS

Diagnosis of abdominal TB requires high index of suspicion, and the treatment should be prompt to reduce the morbidity and mortality associated with delay in treatment.

Effect of ursodeoxycholic acid on liver regeneration capacity after living donor hepatectomy: a prospective, randomized, double-blind clinical trial

OBJECTIVE

Ursodeoxycholic acid (UDCA) has multiple hepatoprotective activities: it modifies the bile acid pool, decreases levels of endogenous, hydrophobic bile acids while increasing the proportion of nontoxic hydrophilic bile acids. It also has cytoprotective, antiapoptotic, and immunomodulatory properties. The aim of this study was to analyze the effect of postoperative administration of UDCA on liver regeneration capacity.

PATIENTS AND METHODS

This is a single-center, prospective, randomized, double-blind study that was carried out in our Liver transplant Institute. Sixty living liver donors (LLDs) who underwent right lobe living donor hepatectomy were divided into two groups using computer-generated random numbers: one group received oral UDCA 500 mg 12 hourly for 7 days (UDCA group; n=30) from the first postoperative day (POD) and the other did not receive UDCA (non-UDCA group; n=30). Both groups were compared in terms of the following parameters: clinical and demographic parameters, liver enzymes (ALT, AST, ALP, GGT, total bilirubin, direct Bilirubin), and INR.

RESULTS

The median ages in the UDCA and non-UDCA were 31 years (95% CI for median: 26-38) and 24 years (95% CI for median: 23-29), respectively. Liver function tests showed significant differences at various times within the first seven PODs. The INR was lower in UDCA group patients on POD3 and POD4. However, GGT was significantly lower on POD6 and POD7 for the UDCA group. Total bilirubin was also significantly lower on POD3 for the UDCA group patients, but ALP was lower all from POD1 to POD7. A significant difference was also observed in AST on POD3, POD5 and POD6.

CONCLUSIONS

Postoperative administration of oral UDCA significantly improves liver function tests and INR among LLDs.

Factors affecting anxiety, depression, and stress among patients with hepatocellular carcinoma during COVID-19 pandemic

OBJECTIVE

Patients with chronic disease whose treatments are limited may experience depression, anxiety, and stress-related symptoms, as well as an increase in the levels of these conditions. This study aims to determine the factors affecting the depression, stress, and anxiety levels of hepatocellular carcinoma (HCC) patients due to the fear of COVID-19 exposure.

PATIENTS AND METHODS

118 patients with advanced HCC treated with non-transplant treatment options or on the waiting list due to the lack of a donor were enrolled. To evaluate the stress, depression, and anxiety levels during the COVID-19 process, Depression Anxiety Stress Scales (DASS-21) and the Coronavirus Anxiety Scale (CAS) were administered to 118 patients through a face-to-face interview. Sociodemographic and clinical characteristics were recorded, and the primary endpoint measure was the total score of DASS. In addition, the multilayer perceptron (MLP) model was constructed to predict the scores of the DASS-21 total.

RESULTS

There were significant differences between DASS depression (p=0.010; p=0.030) DASS anxiety (p=0.010; p=0.010) and DASS total (p=0.046; p=0.023) scores in terms of gender and protective effect of the vaccine. Also, a significant difference between gender for the CAS scale was determined (p=0.044). The median score of the DASS total in the COVID-19 group was higher than in the non-COVID-19 group; however, the increase was not significant. MLP model revealed that chronic disease, gender, age, place of residence, smoking, type of vaccine, and COVID-19 exposure were the most important predictors for the DASS total.

CONCLUSIONS

Chronic disease, gender, and age were prominent factors in predicting the DASS-21 total score in HCC patients. Therefore, the crucial factors were clinically considered for managing depression, stress, and anxiety in HCC patients.

Surgical Treatment of Catamenial Chest Pain: Excision of diaphragmatic endometriosis during robot-assisted laparoscopic surgery

Background

10% of women of reproductive age are affected by endometriosis, and diaphragmatic endometriosis represents 1-1.5% of these cases. Diaphragmatic endometriotic lesions often require surgical treatment.

Objective

This video aims to demonstrate the appearance of diaphragmatic endometriosis and describe our experience with robot-assisted laparoscopic excision of full thickness diaphragmatic endometriosis.

Materials and Methods

The patient was a 37-year-old female with the complaint of cyclical right shoulder pain (for 1 year). She previously had caesarean section scar and umbilical endometriosis excision procedures. The magnetic resonance imaging (MRI) of the abdomen highlighted three endometriotic nodules, one of which was described as full thickness on the right hemi-diaphragm. The patient underwent a robot-assisted laparoscopic endometriosis surgery as a joint procedure between the gynaecology and general surgery teams. The falciform ligament was completely divided to obtain full views of the endometriotic lesions on the diaphragm. Superficial diaphragmatic lesions were first excised. The larger deep nodule, which was described on the MRI, was then excised with the full thickness of diaphragm. Pleural cavity was entered intentionally to achieve complete excision of the nodule. Laparoscopic assessment of the right lower pleural cavity through this opening did not show any endometriotic lesions. After the excision, the diaphragm was repaired with a barbed suture. Negative pressure suction of the pleural cavity was performed at the end of this repair instead of using a chest tube.

Results

The patient was discharged on the 3rd day with no complications encountered. Histopathological examination confirmed endometriosis. The patient was asymptomatic three months after surgery.

Conclusion

Robotic-assisted surgery is an easy and safe choice especially in such challenging dual compartment surgeries by providing a 3D view that abolishes sensory loss and increases depth perception, providing better manoeuvrability with tremor absence.

Histopathological, immunohistochemical and biochemical evaluation of electroacupuncture treatment of nervus radialis and nervus ulnaris injuries in rabbits

The aim of this study was to evaluate the efficacy of electroacupuncture in acute and chronic phases of radial and ulnar nerve injuries in histopathological, immunohistochemical and biochemical aspects. In the study, the rabbits were divided into four groups namely acute nerve injury (ANI) group, chronic nerve injury (CNI) group, positive control (PC) group and negative control (NC) group. In the ANI, CNI and PC groups, damage was created on the nervus radialis and nervus ulnaris by applying pressure for 60 seconds using a hemostatic forceps under anesthesia. No damage was created in the NC group. Fifteen sessions of electroacupuncture were applied to the rabbits in the ANI, CNI, and NC groups every other day using LI-4 (Large Intestine Meridian-4, He Gu), LI-10 (Large Intestine Meridian-10, Shou San Li), LR-3 (Liver Meridian-3, Tai Chong), and ST-36 (Stomach Meridian-36, Zusanli) electroacupuncture points. Electroacupuncture was not applied to the rabbits in the PC group. Decapitation was performed under general anesthesia at the end of electroacupuncture applications. After the euthanasia procedure, the samples obtained were evaluated for histopathological, immunohistochemical and biochemical parameters. In conclusion, degenerative foci in the treatment groups were found to be fewer than in the PC group whereas NGF and S-100 immunoreactivity were higher in the treatment groups than in the PC group. Whereas no statistically significant difference was observed between the treatment groups and the NC group in terms of oxidative stress factors, there was a statistically significant difference between the treatment groups and the PC group. In light of all these data, we have concluded that electroacupuncture is an effective treatment method for peripheral nerve injuries.

Doxorubicin-induced oxidative stress injury: The protective effect of kumiss on cardiotoxicity

Bu çalışmanın amacı, doksorubisinin (DOX) neden olduğu kardiyotoksisite üzerine kımızın etkisini araştırmaktı. Yirmi sekiz Wistar-Albino erkek sıçan 4 gruba ayrıldı: Birinci gruba (kontrol) herhangi bir müdahale yapılmadı. İkinci gruba 7 gün gavaj yoluyla 2 ml/kg/gün, üçüncü gruba intraperitoneal DOX, dördüncü gruba kımız+DOX 20 mg/kg tek doz verildi. DOX uygulamasından 7 gün önce Kumiss uygulamasına başlandı ve 7 gün devam edildi. 7 On thkımız uygulamasının ilk gününde intraperitoneal olarak DOX uygulandı. Malondialdehit (MDA), indirgenmiş glutatyon (GSH) seviyeleri ve katalaz (CAT), glutatyon peroksidaz (GSH-Px), süperoksit dismutaz (SOD), glukoz-6-fosfat dehidrojenaz (G6PD) ve glutatyon-S- gibi antioksidan enzimler Kalp ve kan dokularında kardiyotoksisite patogenezindeki etkinliklerini belirlemek için transferaz (GST) aktiviteleri belirlendi. DOX grubu kontrol grubu ile karşılaştırıldığında MDA (p<0,001, p<0,001) ve GSH (p<0,001, p=0,002) düzeylerinde artış ve CAT'de azalma (p=0,001, p<0,001) , GSH-Px (p<0.001, p<0.001), G6PD (p<0.001, p=0.001) ve GST (p=0.003) aktiviteleri bulundu ve SOD aktivitesinde istatistiksel olarak anlamlı fark bulunmadı.

Sonuç olarak, lipid peroksidasyon ürünlerindeki artış ve antioksidan enzimlerdeki azalmanın, güçlü bir kemoterapötik ilaç olan DOX ile indüklenen kardiyotoksisitenin patogenezinde rol oynayabileceği belirlendi ve kırmızının DOX kaynaklı oksidatif hasara karşı koruduğu gösterildi.

Vessel sealing system vs. conventional knot-tying for hilar dissection during living donor hepatectomy: a prospective, randomized, double-blinded study

OBJECTIVE

LT has become the gold standard treatment for many liver diseases, especially chronic liver disease. A commonly seen problem, even in donors who do not develop any major complications after living donor hepatectomy (LDH), is the persistent drainage of lymphatic fluid from the hepatectomy site drain, which causes extensive hospitalization and consequent loss to the workforce. To our knowledge, no study has yet been published comparing LVSS and conventional knot-tying methods for hilar dissection, which is an important stage of the LDH procedure. We aimed to prospectively compare the outcomes of these two treatment methods.

PATIENTS AND METHODS

Donor candidates were divided into two groups: conventional suture tying (conventional knot tying group; n=34) and Ligasure vessel sealing system (LVSS; n=34). A simple randomization method of drawing lots was used to assign the patients to each group. The following parameters were analyzed for all patients: age, gender, BMI, duration of surgery, postoperative drainage amounts, drain removal times and complications, length of hospital stay, morbidity, and mortality.

RESULTS

There were no significant differences in terms of operative times, postoperative drainage levels, hospital stay or drain removal times.

CONCLUSIONS

In this study, the use of LVSS in LDH was found to be safe, although it did not offer any advantage over conventional methods. Nevertheless, it seems probable that the use of LVSS could reduce operative time and amounts of lymphatic drainage, especially in centers with minimal experience with LDH, such as new LDH centers.

Quality of life, disease activity and preferences for administration routes in rheumatoid arthritis: a multicentre, prospective, observational study

Objective

We aimed to evaluate quality of life (QoL), disease activity, compliance to treatment, patient and physician preferences for route of administration (RoA), status of health and pain in RA patients starting advanced treatments or needing a switch, and the factors associated with patient preferences.

Methods

A multicentre, prospective, observational and 1-year follow-up study was conducted, between 2015 and 2020, in adult RA patients using advanced treatments for the first time or needing a switch in their current treatments. All the data collected were entered into electronic case report forms. DAS in 28 joints with ESR [DAS28-4(ESR)], EuroQol 5-Dimensional Questionnaire (EQ-5D), HAQ Disability Index (HAQ-DI), Compliance Questionnaire for Rheumatology (CQR-19), Work Productivity and Activity Impairment Instrument (WPAI) and Patient Global Assessment-Visual Analogue Scale (PGA-VAS) questionnaires were used for longitudinal assessments.

Results

Four hundred and fifty-nine patients were enrolled. Three hundred and eight patients (67.1%) attended the final study visit at 12 months and were included for comparative analyses. Irrespective of RoA, the disease activity and QoL improved significantly at 12 months, whereas compliance worsened. At baseline and 12 months, EQ-5D and DAS28-4(ESR) scores were significantly correlated (P < 0.001). The WPAI scores changed significantly in favour of better outcomes over 12 months after initiation of advanced treatment or switching (P < 0.001). A higher proportion of patients preferred an oral RoA, in comparison to physicians (53.6% vs 31.4%; P < 0.001). Patient and physician RoA preferences were independent of gender, age, disease duration, advanced treatment type and the EQ-5D-3L, DAS28-4(ESR), HAQ-DI, PGA-VAS and CQR-19 scores at baseline.

Conclusion

The oral route was more frequently preferred by patients compared with physicians, although patients’ preference rates showed a slight increase towards the end of the treatment, which might be an important factor for RA outcomes. Better control of disease activity and QoL were achieved at 12 months, regardless of RoA.

Diffusion-weighted imaging of the liver in assessing chronic liver disease: effects of fat and iron deposition on ADC values

OBJECTIVE

This study was designed to evaluate whether fat and iron affect the apparent diffusion coefficient (ADC) values of the liver parenchyma in the settings of fibrosis and inflammation.

PATIENTS AND METHODS

We evaluated the diffusion-weighted images (DWIs) of 58 patients with chronic liver disease and 48 control subjects. Liver specimens of patients were assessed for fibrosis, necroinflammation, iron, and steatosis. Liver ADCs, spleen ADCs, and normalized liver ADCs (defined as the ratio of the liver ADC to spleen ADC) values were analyzed after stratifying patients with either fibrosis stages or histology activity index (HAI) scores. The relationship between ADC values and histopathological findings was studied using multiple linear regression analysis.

RESULTS

The median liver and normalized liver ADC values were significantly lower in higher stages of fibrosis and HAI scores. Compared to the control group, patients with the highest stages of fibrosis and inflammation had significantly higher spleen ADCs. The effect of the fibrosis stage on liver ADC and normalized liver ADC values was significant in the setting of inflammation, whereas the degree of steatosis and iron grade did not affect these ADC values.

CONCLUSIONS

ADC values can distinguish both later stages of liver fibrosis and inflammation. There is no significant effect of fat and iron on ADC values. Therefore, DWI may be reliable in evaluating liver fibrosis and inflammation.

Protocol paper: Multi-site, cluster-randomized clinical trial for optimizing functional outcomes of older cancer survivors after chemotherapy

BACKGROUND

Cancer survivors over the age of 65 have unique needs due to the higher prevalence of functional and cognitive impairment, comorbidities, geriatric syndromes, and greater need for social support after chemotherapy. In this study, we will evaluate whether a Geriatric Evaluation and Management-Survivorship (GEMS) intervention improves functional outcomes important to older cancer survivors following chemotherapy.

METHODS

A cluster-randomized trial will be conducted in approximately 30 community oncology practices affiliated with the University of Rochester Cancer Center (URCC) National Cancer Institute Community Oncology Research Program (NCORP) Research Base. Participating sites will be randomized to the GEMS intervention, which includes Advanced Practice Practitioner (APP)-directed geriatric evaluation and management (GEM), and Survivorship Health Education (SHE) that is combined with Exercise for Cancer Patients (EXCAP©®), or usual care. Cancer survivors will be recruited from community oncology practices (of participating oncology physicians and APPs) after the enrolled clinicians have consented and completed a baseline survey. We will enroll 780 cancer survivors aged 65 years and older who have completed curative-intent chemotherapy for a solid tumor malignancy within four weeks of study enrollment. Cancer survivors will be asked to choose one caregiver to also participate for a total up to 780 caregivers. The primary aim is to compare the effectiveness of GEMS for improving patient-reported physical function at six months. The secondary aim is to compare effectiveness of GEMS for improving patient-reported cognitive function at six months. Tertiary aims include comparing the effectiveness of GEMS for improving: 1) Patient-reported physical function at twelve months; 2) objectively assessed physical function at six and twelve months; and 3) patient-reported cognitive function at twelve months and objectively assessed cognitive function at six and twelve months. Exploratory health care aims include: 1) Survivor satisfaction with care, 2) APP communication with primary care physicians (PCPs), 3) completion of referral appointments, and 4) hospitalizations at six and twelve months. Exploratory caregiver aims include: 1) Caregiver distress; 2) caregiver quality of life; 3) caregiver burden; and 4) satisfaction with patient care at six and twelve months.

DISCUSSION

If successful, GEMS would be an option for a standardized APP-led survivorship care intervention.

AB0533 THE ASSESSMENT OF CLINICAL CHARACTERISTICS OF MALE SYSTEMIC LUPUS ERYTHEMATOSUS PATIENTS

Background

Systemic lupus erythematosus (SLE) is a multisystemic chronic autoimmune disease that is nine times more frequent among females. Due to a female dominancy, the data regarding male patients is limited.

Objectives

This study aimed to evaluate the clinical characteristics of male patients with SLE.

Methods

This retrospective study included male SLE patients who followed up in a tertiary rheumatology outpatient clinic between October 2016 and December 2021. Those who met the Systemic Lupus International Collaborating Clinics (SLICC) criteria were included. The data of the patients and SLE Disease Activity Index-2000 (SLEDAI-2K) values were obtained from files.

Results

There were 40 male SLE patients with a mean age of 42.7 ± 17.3 years. The median age of diagnosis was 30 years, and the median disease duration was 63.5 months (ranges between 5-444). The mean value of the SLICC score was 4.7 ± 0.8. The most frequent initial clinical manifestations were thrombocytopenia and photosensitivity, which were seen in 8 (9.6%) patients each (Table 1). Six (15%) patients had secondary antiphospholipid antibody syndrome. Thirty-five (87.5%) patients achieved remission, but 14 (35%) patients had at least one relapse in the follow-up period. The most frequent manifestation after relapse was nephritis in 9 (22.5%) patients that had no renal involvement at the time of diagnosis. The median SLEDAI score was 2 (ranges between 0-12). The most commonly preferred drug for the treatment was hydroxychloroquine and corticosteroids (92.5% for each). Nineteen (47.5%) patients received pulse steroids. Besides, the most frequently prescribed immunosuppressive drug was mycophenolate mofetil (37.5%). The rates of azathioprine, cyclophosphamide, methotrexate, cyclosporine A, rituximab, intravenous immunoglobulin, and leflunomide usage were 30%, 27.5%, 17.5%, 10%, 7.5%, 7.5%, 5%, respectively. Antinuclear antibody (ANA) was positive in 35 (87.5%) patients, and anti-dsDNA was positive in 9 (22.5%). The median level of anti-dsDNA titers was 40 IU/ml (ranges between 23-200). Other autoantibody positivity rates were; 12 (30%) for anti-Sm, 6 (15%) for anti-histon, 4 (10%) for anti-RNP and 4 (10%) for anti-nucleosome. Thirteen (32.5%) patients had low C3 levels, and 11 (27.5%) patients had low C4 levels. The hospitalisation rate was 55%, and no death was seen during follow-up.

Conclusion

Since SLE is more prevalent among females, it may occur in male patients with mild or life-threatening manifestations. In the current study, the seropositivity was less than in the literature, which may indicate male patients should be cautiously evaluated. Although renal involvement is not an initial manifestation, it may develop during the follow-up.

Identification of bacterial species in milk by MALDI-TOF and assessment of some oxidant-antioxidant parameters in blood and milk from cows with different health status of the udder

This study aimed to identify bacterial pathogens in milk samples from dairy cows with subclinical and clinical mastitis as well as to assess the concentrations of oxidant-antioxidant parameters [malondialdehyde (MDA), reduced glutathione (GSH), and total GSH levels] in both blood and milk samples. From a total of 200 dairy cows in 8 farms, 800 quarter milk samples obtained from each udder were tested in the laboratory for the presence of udder pathogens. Cultivated bacteria causing intramammary infection from milk samples were identified by Matrix-Assisted Laser Desorption/Ionization-Time of Flight (MALDI-TOF). In addition, from tested animals 60 cows were selected includıng 20 healthy cows that were CMT negative, 20 cows with subclinical mastitis (SM), and 20 cows with clinical mastitis (CM) for detection of MDA, GSH, and total GSH levels in blood and milk samples. Three hundred and eighty (47.5%; 380/800), 300 (37.5%; 300/800), and 120 (15%; 120/800) of milk samples, respectively were CMT positive or SM and CM, and those positives were cows from different farms. We observed that 87.4% (332/380), 25.3% (76/300), and 34.2% (41/120) of cows with CMT positive, CMT negative, and CM had bacterial growth. The most predominantly identified bacteria were Staphylococcus chromogenes (18.7%) obtained mainly from SM and Staphylococcus aureus (16.7%) as the most frequent cause of CM. According to our results, dairy cows with CM had the highest MDA levels, the lowest GSH, and total GSH levels in both blood and milk samples however, high MDA levels and low GSH levels in milk samples with SM were observed. Based on our results, lipid oxidant MDA and antioxidant GSH could be excellent biomarkers of cow's milk for developing inflammation of the mammary gland. In addition, there was no link between nutrition and MDA and GSH levels.

AB0420 UNINTENTIONAL MONOTHERAPY IN RHEUMATOID ARTHRITIS PATIENTS RECEIVING TOFACITINIB AND DRUG SURVIVAL RATE OF TOFACITINIB

Background

Combination of MTX with a bDMARDs or tsDMARDs is considered the most effective treatment regimen currently available for patients with RA who have failed to respond to conventional DMARDs. However, approximately 30% of patients receive bDMARDs as monotherapy in daily clinical practice. Studies in the literature do not assess unintentional monotherapy in general. However, it is thought that some patients may switch to monotherapy unintentionally. In other words, some patients who are prescribed combination therapy switch to monotherapy without informing their physicians.

Objectives

To determine the rate of unintentional monotherapy in rheumatoid arthritis (RA) patients receiving tofacitinib and to evaluate tofacitinib survival rate.

Methods

This national, multicentre, retrospective study included patients’ data from the TURKBIO Registry. Data on demographics, clinical characteristics, disease duration and activity, comorbidities, and treatment were analysed.

Results

Data of 231 RA patients (84.8% female, median age, 56 years) were included; 153 were initially prescribed combination therapy and continued to their therapies; 31 were initially prescribed combination therapy but switched to monotherapy of their own will (unintentional monotherapy); 21 were initially prescribed monotherapy and switched to combination therapy; 26 were initially prescribed monotherapy and continued to their therapies. The combination and unintentional monotherapy groups did not differ regarding remission rate assessed by DAS28-CRP (60.5% and 70%, respectively, p=0.328). The rate of comorbidities at the time of data retrieval was significantly higher in the unintentional monotherapy group compared with the combination group (83.3% vs. 60.3%, p=0.031). Presence of comorbidities was a significant factor affecting switching to monotherapy (p=0.039, Odds ratio: 3.29, 95% CI: 1.06-10.18). Drug survival rates of the unintentional monotherapy and combination groups did not differ. The median drug survival duration of tofacitinib was 27+ months with a 1-year and 4-year drug survival rates of 89.6% and 60.2%, respectively, in the unintentional monotherapy group.

Conclusion

Although 13.4% of the study population started monotherapy unintentionally, drug survival rates of the unintentional monotherapy and combination groups were not different. Comorbidity was an important factor affecting transition from combination therapy to monotherapy.

This study was sponsored by Pfizer.

POS1357 THE 10-YEAR OUTCOME OF PATIENTS WITH BEHCET’S SYNDROME: A SINGLE-CENTER EXPERIENCE

Background

Behcet’s syndrome (BS) is a vasculitis characterized by recurrent oral and genital ulcers, as well as ocular, cutaneous, vascular, gastrointestinal, musculoskeletal, and central nervous system manifestations.

Objectives

The study aimed to evaluate the 10-year outcome of patients with BS.

Methods

A cohort of 682 patients diagnosed with BS between January 2007 and December 2009 in the rheumatology outpatient clinic of Gulhane Training and Research Hospital were re-evaluated in November 2021. The data regarding the clinical course of 84 patients (84/682) were obtained from patients’ files and detailed telephone interviews.

Results

The study included 84 patients (63 male, 21 female) with a mean age of 47.1±10.6 years. The mean disease duration was 17.6±5.7 years. At the time of the diagnosis, the mean age of the patients was 29.5±9.4 years. Oral ulcer (100%), papulopustular lesions (82.1%), genital ulcer (77.4%), and erythema nodosum (59.5%) were the most frequent manifestations at the time of diagnosis. Ocular (46.4%), musculoskeletal (35.7%), vascular (19%), gastrointestinal (3.6%), and neurological (1.2%) manifestations were seen in decreasing frequency. The most frequent ocular disease was posterior uveitis, whereas superficial thrombophlebitis and deep venous thrombosis were the most prevalent forms of vascular involvement. One patient had transverse myelitis as neurological involvement. Colchicine (88.1%) and corticosteroids (57.1%) were the most preferred drugs for the initial treatment. Fifty-one (60.7%) patients received at least one immunosuppressive agent. After 10-year, there was a statistically significant decrease in all manifestations of BS (Table 1). Nevertheless, 9 (10.7%) patients (8 male, 1 female) had new clinical findings. Five patients had (5.9%) mucocutaneous, 2 (2.4 %) arthritis and 2 (2.4%) vascular lesions as new clinical manifestations. The mean age of the patients with newly onset clinical findings was 48±8.9 years. There was no statistically significant difference between patients with and without new clinical findings with respect to age (p=0.79). The new onset mucocutaneous manifestations were genital ulcer and erythema nodosum. Besides, new onset vascular lesions were superficial and deep venous thrombosis of the lower extremities. The mean age of the patients who developed venous thrombosis at the time of the assessment was 37.0±7.07 years. Vascular involvement was detected more frequently in younger patients (p=0.03). However, ocular involvement is a frequent symptom after mucocutaneous involvement at the beginning, none of the patients had new eye involvement at the end of the follow-up. Colchicine, corticosteroid, and azathioprine were associated with the highest drug survival. Twenty-one (41.1%) patients of who were administered immunosuppressive agents as initial therapy were still using immunosuppressives 10 year later. The most frequently prescribed immunosuppressives were azathioprine and cyclosporine during the follow-up.

AB1088 COVID-19 VACCINATION OF SPONDYLOARTHRITIS PATIENTS RECEIVING BIOLOGICAL THERAPY: REAL-LIFE DATA

Background

Considering the concerns regarding COVID-19 vaccine safety among patients with rheumatic diseases due to a lack of data, an urgent need for studies evaluating safety profiles of vaccines emerged.

Objectives

Vaccination against the coronavirus disease-2019 (COVID-19) started in March 2021 in the group using biological therapy in our country. In this study, post-vaccine real-life data of patients with spondyloarthritis (SpA) followed up with biological therapy were analyzed.

Methods

Adult patients diagnosed with SpA who were followed up under biological therapy and vaccinated by CoronaVac inactive SARS-CoV-2 orBNT162b2 messenger RNA (mRNA) COVID-19 (Pfizer-BioNTech) vaccine were included in our observational, multicenter, prospective study.

Results

A total of 287 patients (58.2% male; mean age: 47) were included in the study. 202 (%70,4) of patients were being followed up with the diagnosis of AS, 40 (%13,9) of them with PsA, 32 (%11,1) of them with nr-axSpA, 11 (%3,8) of them with enteropathic arthritis, and 2 (%0,7) of them with uSpA. The most common comorbidities were found to be HT (n:65; 22.6%) and DM (n:38; 13.2%). While 221 (77%) of the patients were receiving biological therapy alone, 27 (9.4%) patients were using methotrexate, 25 (8.7%) patients were using sulfasalazine, and 12 (4.2%) patients were using leflunomide. The median duration of biological therapy was 40 weeks (19-75 IQR). The most commonly used treatment was infliximab (26.8%), adalimumab (23.3%) was the second (Table 1).

It was determined that 207 (72.1%) of the patients preferred inactivated virus vaccine, while 80 (27.9%) preferred mRNA vaccine. When the time between the biological treatment and the day of vaccination is examined, detected median time between biological treatment and the first dose of vaccination is 11.5 days (5-19 IQR), between the first dose of vaccination and biological treatment is 14 days (7-21 IQR), between treatment and the second dose of vaccine is 14 days (5-23.5 IQR), and between the second dose of vaccine and the next biological treatment is 12.5 days (7-15 IQR). While 25 (8.7%) of the patients had COVID-19 infection before vaccination, 7 (2.4%) patients were found to have COVID-19 after vaccination (p<0.001). While two of the patients who had COVID-19 infection in the pre-vaccination period required hospitalization, none of the patients who had COVID-19 in the post-vaccination period required hospitalization.

The rate of patients who developed side effects after the first dose of the vaccine was 20.6%. The side effects seen, respectively, were detected as pain-redness at the injection site (16%), fatigue (11.8%), headache (8.4%), muscle-joint pain (7.3%) and fever (5.6%). The rate of patients reporting side effects after the second dose of the vaccine was 17.1%. The incidence of side effects after mRNA vaccine was found to be statistically significant compared to inactivated virus vaccine in terms of both doses (p=0.011, p<0.001). Major side effects such as myocarditis, anaphylaxis-angioedema, myocardial infarction, and thrombosis were not observed in any of the patients included in the study. There was no evidence of disease activation in the median follow-up of 209 days (145-280 IQR) after vaccination.

Conclusion

During the follow-up of the patients during the study, no major vaccine-related side effects, post-vaccine disease activation and the need for treatment change were not detected. In order to more accurately evaluate the efficacy of the vaccination program in the patient population using biologic agents, larger-scale studies including unvaccinated individuals are needed.

AB0766 Biologic Drug Preferences of Turkish Rheumatologists in Spondiloartropathy Patients with Advanced Chronic Renal Disease

Background

Biological therapies are the main treatment options for patients with active spondyloarthropathy (SpA) who do not respond to nonsteroidal anti-inflammatory drugs or conventional synthetic disease-modifying drugs. Kidney diseases are not a contraindication to biologic therapies. However, there are some safety concerns for these drugs for patients with advanced chronic kidney disease. De novo infection or recurrence of infections are the main challenges in patients with multiple comorbidities during biologic treatments. Neverthless, physicans should initiate these treatments in active and resistant diseases.

Objectives

Here, we evaluated which biologic therapies clinicians’ first option to initiate in SpA patients with advanced chronic kidney disease (CRD).

Methods

Total 140 patients of TREASURE database who fullfield axial and/or peripheral ASAS SpA criteria with glomerular filtration rate < 60 ml/dk (stage 3,4 or 5 CRD according to The National Kidney Foundation classification) were included to the study. Renal stages of the patients were evaluated when biologic therapy was initiated. Five anti-TNF (adalimumab, certolizumab, etanercept, golimumab, infliximab) and an interleukin-17A blocker (secukinumab) were on the market during the study. We evaluated physicans’ first choice for biologic therapy for patients with stage 3,4 and 5 CRD respectively.

Results

More than two thirds of the patients had stage 3 CRD. Anti-TNF drugs were the first choice of biologic treatment in the patients with advanced CRD. Etanercept was started at most to the patients in general, in stage 3 and in stage 5 CRD groups. However, adalimumab was the first choise in stage 4 CRD. Both etanercept and adalimumab were the first drug of choise in three fourth of the stage 4 and stage 5 patients. All two patients on Il-17A blocker had stage 3 CRD (Table 1).

Conclusion

We show that rheumatologists in the TREASURE group prefer to initiate anti-TNF drugs first in all advanced CRD stages. Etanercept was the first choice in these patients.

POS1195 CAN PRE-TREATMENT INFLAMMATORY BIOMARKER LEVELS GUIDE TO DETERMINE APPROPRIATE TIME OF TOCILIZUMAB THERAPY IN COVID-19

Background

Due to the pleiotropic cytokine interleukin-6 (IL-6) plays a pivotal role in the pathogenesis of COVID- 19, tocilizumab, an inhibitor of the IL-6 receptors, was considered as an attractive therapeutic option. When the inflammation cascade is excessive and therapy is delayed, the efforts for suppression of inflammation does not necessarily reduce mortality in all cases. Besides, early using anti-cytokine therapy may lead to both increased cost and risks including iatrogenic immunosuppression (1). Defining of patients who will benefit from tocilizumab and determining optimal timing of tocilizumab will prevent drug-related side effects and increased costs due to unnecessary drug use.

Objectives

To investigate the reliability of pre-treatment levels of prognostic nutritional index (PNI), C-reactive protein/albumin ratio (CAR), systemic immune-inflammatory index (SII), IL-6, lactate dehydrogenase (LDH) as a treatment response biomarker in hospitalized COVID-19 patients who administered tocilizumab.

Methods

One hundred thirty three COVID-19 patients received tocilizumab were included. The end-points of treatment effectiveness were evaluated with the rate of death and emerging need for mechanical ventilation at 28 days of hospitalization. To determine independent mortality risk factors, multivariate logistic regression analyzes were performed for statistically different variables among groups that were statistically different in univariate analysis. The capacity of IL-6, CAR, PNI, SII and LDH values in predicting of tocilizumab response in COVID-19 patients were analyzed using receiver operating characteristic (ROC) curve analysis.

Results

34 (25.56%) patients died after tocilizumab therapy. Patients who improved after tocilizumab were significantly younger and had significantly lower IL-6, LDH, SII, CAR and higher PNI than patients who died. In univariate analyses, mortality was significantly associated with age, IL-6, LDH, PNI, SII, CAR and CRP. In multivariate analysis, age (OR:1.070, 95%CI:1.019-1.124, p:0.007) and LDH (OR:1.006, 95CI%:1.003- 1.010, p<0.001) were found to be independent predictors of mortality after tocilizumab therapy. To identify of tocilizumab response in COVID-19 patients, IL6 had the highest area under curve (AUC) value (AUC:0.782, 95%CI:0694-0.870), followed by LDH (AUC:0.761, 95%CI:0.661-0.861), PNI (AUC:0.696, 95%CI:0.584-807), SII (AUC:0.671, 95%CI:0.551–0.790), CAR (AUC:0.682, 95%CI:0.578– 0.786) and CRP (AUC:0.643, 95%CI:0.535–0.751). Predictive performance of inflammatory biomarkers in the prediction of mortality after tocilizumab therapy was presented in Table 1.

Although the patients with significantly lower IL-6, LDH, SII, CAR and higher PNI levels improved after tocilizumab therapy, only serum LDH levels and age were found to be as independent predictors of mortality. To specify the optimal time interval and the patients who will benefit from tocilizumab, these biomarkers may be used.

AB0762 Incidence Of Anterior Uveitis In Axial Spondyloarthritis During Secukinumab Treatment: TWO YEARS REAL LIFE EXPERIENCE FROM TURKBIO REGISTRY

Background

Secukinumab (SEC), a human anti-IL-17A monoclonal antibody, has similar treatment response rates to tumor necrosis factor (TNF) inhibitors in patients with axial spondyloarthritis (SpA). However, the efficacy of SEC on anterior uveitis (AU) is unclear.

Objectives

This study aimed to evaluate the risk of new-onset or relapsing AU in axial SpA patients treated with SEC.

Methods

In this prospective cohort study, 130 axial SpA patients receiving SEC at the TURKBIO registry between 2019 and 2021 were evaluated. Demographic and clinical characteristics and data about the presence of AU pre or post-treatment were collected. The univariate and multivariate logistic regression analyses were performed to evaluate the predictors of AU development.

Results

The mean age of the patients (F/M: 59/71) was 47.4±10.9 years. The median follow-up time was 540 days (IQR: 330-630). SEC was the first biological agent in 50 (38.4%) patients and 35 (26.9%) patients were using at least one concomitant conventional synthetic DMARD (Table 1). While continued SEC therapy was in 93 (71.5%) patients, treatment withdrawal was in 37 cases (in 26 due to ineffectiveness, two adverse events and nine other reasons). Overall, 15(11.5%) patients had a history of AU before the SEC. During follow-up, AU attacks were seen in the 6 cases (4 were new-onset and 2 were flare) and 5 of these patients have a history of inadequate response to TNF inhibitors. The frequency of AU was calculated as 3.42 per 100 patient-years during SEC treatment. The only significant predictor of AU development was the baseline high C-reactive protein (CRP) level on multivariate analysis (p=0.003, OR: 1.063 [95% CI 1.021-1.107]).

AB1276 EVALUATION OF DRUG-FREE REMISSION RATES IN IDIOPATHIC GRANULOMATOUS MASTITIS

Background

Idiopathic granulomatous mastitis (IGM) is a rare inflammatory breast disease. There is no clear consensus on its treatment yet (1).

Objectives

The aim of the study was to evaluate the rates of drug-free remission of the patients with IGM in a period of three-year follow-up.

Methods

A total of 76 patients who were followed-up with biopsy proven IGM, between February 2011 and November 2021 in rheumatology outpatient clinic of Gulhane Training and Research Hospital, were evaluated retrospectively. To analyze long-term outcomes, 55 patients who were followed up for 3 years were included in the study. Data regarding the demographic and clinical characteristics of the patients were obtained from patients’ files.

Results

The study included 55 female patients with a mean age of 36.8 ± 6.3 years. Forty-nine (89.1%) patients received immunosuppressive treatment, one (1.8%) patient received postoperative immunosuppressive treatment, 3 (5.4%) patients had immunosuppressive treatment due to recurrence after surgery, and 1 (1.8%) patient underwent only surgery. One (1.8%) patient had no treatment for IGM. Patients who received immunosuppressive drugs for initial treatment, 38 (69.1%) received methotrexate (MTX) and corticosteroids (CS), 7 (13.2%) received azathioprine (AZA) and CS, 3 (5.6%) received only CS and 1 (1.8%) received cyclosporine A (CsA) and CS. Four (7.2 %) patients had received MTX after surgery. At 3-year follow-up 54 (98.1%) patients were in drug-free remission. The median duration of drug-free remission in patients receiving MTX plus CS, CS, and azathioprine plus CS was 19.7, 32.9, and 14.7 months, respectively. One patient who received CsA plus CS was in drug-free remission for 28.3 months. The median duration of treatment with combination of CS and other immunosuppressives was 6.7 months. The median duration of immunosuppressive treatment was 15.8 months (Table 1). Recurrence was observed in 4 (80%) patients who did not receive immunosuppressive therapy after surgery. Three (75%) of these patients received MTX due to recurrence, and remission was achieved.

The influence of MTAD and QMix on the accuracy of electronic apex locator in locating simulated perforations

Aims and Background

The aim of this study was to evaluate the accuracy of the electronic actual length in detecting artificial perforations of the root canal in the presence of saline solution (NaCl, (Eczacibasi, Istanbul, Turkey), chlorhexidine [CHX (Werax, Tunadent, Izmir, Turkey)], QMix (Dentsply Tulsa, Maillefer, Ballaigues, Switzerland), and MTAD (Dentsply, Tulsa Dental, Tulsa, OK, USA).

Materials and Methods

The root canals of 25 single-rooted extracted human teeth were perforated artificially in the middle section of the root. The actual lengths up to the perforation site were measured and then, the teeth were embedded in an alginate mold. Electronic measurements of the perforations were obtained by an electronic apex locator according to the manufacturers' recommendations under dry conditions and in the presence of NaCl, CHX, MTAD, and QMix using a #20 K-file. Each canal was irrigated with distilled water and then dried with paper points between the measurements. Statistical analyses were performed using the Friedman test and Spearman Rank correlation coefficient to assess the correlations between the measurement methods.

Results

Highest correlation between the actual length and the electronic measurement was observed under dry conditions and NaCl solution (r: 0.932, r: 0.940 respectively), and the least correlation was observed with MTAD solution (r: 0.697) using statistical analysis. Moreover, the accuracy of the electronic apex locator with different irrigation solutions was statistically different from each other (P = 0.001).

Conclusion

The most accurate electronic measurements of artificial perforation were obtained under dry conditions or with NaCl.

Physicians' Biological Drug Preference in Patients With Rheumatoid Arthritis and Spondyloarthritis With a History of Malignancy: Perspectives From the Treasure Database

OBJECTIVE

Because of concerns about malignancy risks, using biological disease-modifying antirheumatic drugs (bDMARDs) in patients with a history of malignancy remains a challenging issue in rheumatology practice. This study aimed to investigate bDMARD preferences of physicians when treating of rheumatoid arthritis (RA) and spondyloarthritis (SpA) patients with a history of malignancy.

METHODS

The data for this cross-sectional study were gathered from the TReasure database using a date range of December 2017 and January 2020. Biological disease-modifying antirheumatic drug preferences were analyzed for 40 RA patients and 25 SpA patients with a history of malignancy.

RESULTS

The most frequently prescribed bDMARD was rituximab, which was given to 28 RA patients (70%). For 25 patients (62.5%), the time between the diagnosis of malignancy and starting on a bDMARD regimen was less than 60 months, with a median interval of 43.5 months. Among SpA patients, the preferred bDMARDs were secukinumab and etanercept, which were each administered to 7 patients (28%). For 13 SpA patients (52%), the time between the diagnosis of malignancy and starting on bDMARDs was less than 60 months, with a median interval of 97 months.

CONCLUSIONS

The observed bDMARD preferences may be related to the therapeutic effects of rituximab on lymphoproliferative malignancies, the protective effects of secukinumab on tumor progression, and the short half-life of etanercept. Biological disease-modifying antirheumatic drugs should be used in RA and SpA patients with malignancy in case of high inflammatory activity.

The magnetic resonance imaging assessment of optic nerve sheath diameter in pediatric acute liver failure patients

OBJECTIVE

To evaluate the diagnostic value of optic nerve sheath diameter (ONSD) using brain MRI in the pretransplantation period in the pediatric acute liver failure patients, and correlate the ONSD with clinical grade of hepatic encephalopathy (HE) and MRI findings.

PATIENTS AND METHODS

Forty acute liver failure patients and 40 control group patients were retrospectively analyzed. The high signal intensities in T2W (T2-weighted image), FLAIR (Fluid Attenuated Inversion Recovery) and DWI (diffusion-weighted imaging) sequences were evaluated and ONSD was measured. The patients were grouped first into 5 according to their West Haven score, and HE grade 0 and grade 1 were accepted as low grade HE, HE grade 2, 3 and 4 were accepted as high grade HE. The patients were grouped to 2 according to the MRI findings as low grade and high grade MRI group.

RESULTS

The mean value of ONSD was 6.0 ± 1.80 and 4.94 ± 1.27 in the all patients and in the control group, respectively. There was statistically significant difference between both the ONSD and the low grade-high grade HE groups (p=0.01), and between the ONSD and the low grade-high grade MRI groups (p<0.001).

CONCLUSIONS

Although high ONSD values do not make the diagnosis of cerebral edema, it may cause suspicion in the early period. MRI can be helpful in the diagnoses of increased intracranial pressure like ultrasound. Our study is the first study to compare ONSD and MRI findings in addition to HE grades. The widespread use of MRI in children in recent years may help determine the normal range of ONSD values.

Ultrasound-guided wire localization biopsy in non-palpable breast lesions: predictive factors for malignancy

OBJECTIVE

The aim of the study was to evaluate the results of ultrasound-guided excisional biopsy in patients with nonpalpable breast lesions and examine factors associated with malignancy.

PATIENTS AND METHODS

A total of 380 patients who underwent ultrasound-guided excisional biopsy for suspected nonpalpable breast masses, between May 2012 and 2018, were retrospectively examined. Histopathological results of the patients were compared regarding age, ultrasound findings, ultrasonographic and mammographic Breast Imaging Reporting and Data System (BI-RADS) categories and factors predicting malignancy were determined.

RESULTS

The mean age of the patients was 48.35 ± 11.23 (17-86) years. There was a history of breast cancer in the families of 22 (5.8%) patients, and 187 (49.2%) patients were in menopause. The complication rate was found to be 6.6%. Malignant lesions were detected in 76 (20%) patients and benign lesions were detected in 304 (79.99%) patients. Some benign lesions were high-risk lesions (16.8%). Most of the patients with malignant lesions had early-stage breast cancer (83.3%). In univariate analyzes, ultrasonographic BI-RADS, mammographic BI-RADS and age variables were found to be associated with malignancy (p = 0.0001). In the multiple logistic regression analysis, ultrasonographic and mammographic BI-RADS values were found to be risk factors for malignancy (p = 0.0001).

CONCLUSIONS

BI-RADS scoring was used to determine risk factors in predicting malignancy in the evaluation of suspected nonpalpable lesions. The ultrasound-guided wire localization biopsy is a useful method in nonpalpable breast lesions with suspected malignancy that cannot be diagnosed by core/vacuum biopsy or in cases where incompatibility between pathology and radiology results exists.

The Risk of Presarcopenia Is Increased Among Female Patients With Primary Sjögren's Syndrome

OBJECTIVES

Sarcopenia is a progressive and generalized loss of muscle mass and function. The aim of this study was to evaluate the frequency of sarcopenia among patients with primary Sjögren's syndrome (SS) and the factors related with sarcopenia.

METHODS

Forty-four female patients with primary SS and 44 female control subjects were included in this cross-sectional study between February and August 2019. Sarcopenia was evaluated by the handgrip test, Skeletal Muscle Mass Index, and gait speed test.

RESULTS

Eleven patients (25.0%) had presarcopenia in the SS group and 2 (4.5%) in the control group (p = 0.007). Compared with control subjects, SS patients had lower results of hand grip and gait speed tests (p = 0.005 and p < 0.001, respectively). According to the Mini Nutritional Assessment Short Form, patients with presarcopenia had higher risk of malnutrition compared with patients without sarcopenia (p = 0.043). Patients with presarcopenia had higher scores in the European League Against Rheumatism Sjögren's Syndrome Patient-Reported Index pain domain and patient visual analog scale for global disease activity compared with patients without sarcopenia (p = 0.044 and p = 0.036, respectively). In multivariate regression analysis, European League Against Rheumatism Sjögren's Syndrome Patient-Reported Index pain was associated with hand grip strength (p = 0.016, R2 = 0.13) and Mini Nutritional Assessment Short Form was associated with Skeletal Muscle Mass Index (p = 0.005).

CONCLUSIONS

Risk of sarcopenia is increased in patients with SS. Pain and malnutrition may contribute to presarcopenia. Evaluating pain and patient's global disease activity may help physicians to determine patients with increased risk of sarcopenia. Controlling disease activity and pain and preventing malnutrition may reduce the risk of development of sarcopenia.

Randomised controlled study of seroma rates after mastectomy with and without quilting the skin flap to pectoralis muscle

Aims

The aim of this study was to determine whether seroma formation was affected by reduction of the potential dead space with the flap fixation method and obliteration of the axillary region in patients with breast cancer who underwent either mastectomy and axillary lymph node dissection or sentinel lymph node biopsy. A total of 105 patients with breast cancer were divided into two groups according to wound closure patterns.

Patients and Methods

The operating time, postoperative pain and complications, time to drain removal, seroma formation, amount of fluid aspirated and number of aspirations were recorded prospectively.

Results

No significant difference was found between groups in the rates of seroma development (P = 0.7), complication rates (P = 0.6), time to drain removal (P = 0.5), length of hospital stay (P = 0.3) or numbers of aspiration (P = 0.7). The operating time for fixation was determined to be longer than that of the classic procedure (P = 0.02).

Conclusions

Reducing potential dead space with flap fixation and obliteration of the axillary region may be useful in decreasing the development of seroma in patients who have undergone mastectomy because of breast cancer. However, surgical technique must be careful, and appropriate patient follow-up must be conducted.

The effect of hip dysplasia on some biochemical parameters, oxidative stress factors and hematocrit levels in dogs

In this study, it was aimed to investigate the effect of hip dysplasia on some biochemical parameters, oxidative stress factors and hematocrit values in dogs. Hematocrit values (HTC), serum calcium (Ca), phosphorus (P) levels, serum alkaline phosphatase (ALP), creatine kinase (CK) activities and oxidative stress factors were evaluated in a total of 27 dogs with healthy hip joints (n: 11) and hip dysplasia (n: 16). There was no statistically significant difference between the two groups in terms of HCT, Ca and P values (p˃0.05). ALP and CK activities were found to be statistically significantly increased in the group with hip dysplasia compared to the control group with a healthy hip joint (p˂0.05). While malondialdehyde (MDA) level, one of the oxidative stress factors, was increased in the group with hip dysplasia, decreased glutathione (GSH) levels, catalase (CAT) and glutathione peroxidase (GSH-Px) activities were significantly decreased. There was no significant difference between the two groups in terms of superoxide dismutase (SOD) level. As a result, it was determined that oxidative stress factors differ in dogs with hip dysplasia compared to dogs with the healthy hip joint.

P–424 Evaluating the relationship between endoplasmic reticulum stress and recurrent pregnancy loss in a young population cohort

Study question

Does endoplasmic reticulum (ER) stress evaluated by X-box binding protein 1 (XBP–1) among patients aged 18–30 years play a role in recurrent pregnancy loss (RPL)?

Summary answer

High levels of XBP–1 observed in patients with known RPL indicate that ER stress plays an important role in RPL.

What is known already

Female reproductive tract undergoes dynamic changes during oogenesis which require protein synthesis, folding, maturation, which take place in the ER. ER is also responsible for destruction of unfolded/misfolded proteins. Excess accumulation of these faulty proteins leads to ER stress, which actives unfolded protein response (UPR). XBP–1 is a transcription factor involved in UPR and regulates ER stress-mediated apoptosis. Regulation of ER homeostasis is important in folliculogenesis, oocyte maturation and embryogenesis. It is also known that ER stress has a positive correlation with age and it is associated with age-related diseases.

Study design, size, duration

This prospective case-controlled study was conducted at University of Health Sciences Turkey, Istanbul Kanuni Sultan Suleyman Training and Research Hospital Department of Obstetrics and Gynecology between March 2020 – September 2020. A total of 70 subjects were included in the study. All patients gave their written informed consent before their enrollment in the study.

Participants/materials, setting, methods

38 patients aged 18–30 years with a history of RPL were included in the study. Patients who had miscarriages due to fetal abnormalities, patients with infections, endocrine or genetic disorders, smokers, alcohol and/or drug abusers, with acute/chronic inflammatory diseases, patients using steroids, anti-inflammatory and antioxidant medications were excluded from the study. Age-matched 32 healthy subjects without RPL were included in the control group. XBP–1 levels were determined using Human XBP–1 ELISA Kit (Elabscience Co., USA).

Main results and the role of chance

The mean age in the control group and in the study group were 25.21±3.3 and 25.26±2.6, respectively and they were statistically similar (p = 0.324). When groups were compared according to thyroid stimulating hormone (TSH) levels and body mass index (BMI), which are additional risk factors of RPL both groups were statistically similar (p = 0.642 and 0.942, respectively). As expected gravidity and abortus numbers were significantly higher in the study group (p &lt; 0.001). A mean XBP–1 level of 1233.41± 3902.97 was determined in the control group. The mean value of the study group was calculated to be 2251.49± 9621.12. Mean XBP–1 level in the study group was significantly high (p &lt; 0.001). A receiver operating curve (ROC) analysis was conducted in the study group. The area under the curve was found to be 87% (95% CI: 79% - 95%). The specificity was 75%, sensitivity was 89%, positive LR was 3.5, negative LR was 0.15, positive predictive value was 80% and negative predictive value was 87% for the cut-off XBP–1 level at 1364.68 pg/mL.

Limitations, reasons for caution

Small sample size is an important limitation of this study. In addition, evaluating XBP–1 only in serum samples does not let us drive any conclusions on the local changes of ER stress. Studies with larger samples sizes and studying XBP–1 levels in tissue samples of endometrial material is needed.

Wider implications of the findings: The significantly high levels of XBP–1 in RPL patients younger than 30 years, indicate higher ER stress in this group even when age dependent increase in ER stress is calculated out of the equation. XBP–1 can be a promising marker in evaluating patients with a fertility wish for RPL risk.

Tumor multifocality and serum albumin levels can identify groups of patients with hepatocellular carcinoma and portal vein thrombosis having distinct survival outcomes

Background

Macroscopic portal vein thrombosis (PVT) is a major poor prognosis factor in patients with hepatocellular carcinoma (HCC), but constitute a heterogeneous group.

Aims

To examine blood and tumor parameters of 1667 HCC patients who had PVT to identify factors that could differentiate different survival subsets.

Methods

a large HCC database was examined for presence of patients with PVT and analyzed retrospectively for PVT-associated factors and prognosis.

Results

A logistic regression model was calculated for presence of PVT. Highest odds ratios were found for tumor multifocality and serum albumin levels, as well as serum alpha-fetoprotein (AFP) and bilirubin levels. A Kaplan-Meier and Cox model on survival also showed the highest hazard ratios for tumor multifocality and serum albumin. A model was constructed on all 4 possible combinations of tumor focality and serum albumin in PVT patients. The longest survival group had <2 tumor nodules plus serum albumin >3.5 g/dL. Conversely, the shortest survival group had >2 tumor nodules plus serum albumin <3.5 g/dL. These 2 patient groups differed in maximum tumor diameter and levels of serum AFP, AST and bilirubin.

Conclusions

Combination low tumor focality and high serum albumin identifies prognostically better PVT patient subgroups that might benefit from aggressive therapies.

•

Portal vein thrombosis (PVT) is a major poor prognosis factor in HCC patients.

•

We found that the highest odds ratios for PVT included number of tumor foci and serum albumin levels.

•

A model was constructed with all 4 possible combinations of these 2 parameters.

•

The longest survival group had <2 tumor nodules plus normal albumin. Conversely, the shortest survival group had >2 tumor nodules plus low albumin. These 2 PVT groups had a 3-fold difference in survival and had significantly different AFP and bilirubin levels.

•

These findings provide simple patient selection criteria for treating in PVT patients.

POS0929 FACTORS ASSOCIATED WITH THE DEVELOPMENT OF ANTI-DRUG ANTIBODIES TO TUMOUR NECROSIS FACTOR INHIBITORS IN PATIENTS WITH AXIAL SPONDYLOARTHRITIS; A TWO YEAR FOLLOW-UP STUDY

Background:

Axial spondyloarthritis (axSpA) is a chronic inflammatory rheumatic disease affecting sacroiliac joints and spine as well as peripheral joints and entheses. Tumour necrosis factor inhibitors (TNFi) are widely used in patients with persistently high disease activity despite non-steroidal anti-inflammatory drugs. Some patients fail to respond or loose responsiveness during therapy with TNFi. The development of anti-drug antibodies (ADA) might play a role in non-response or some adverse events. However it has never been evaluated for 2-years period.

Objectives:

Therefore, the aim of the present study was to evaluate the development of ADA against TNFi longitudinally during 2-years period in axSpA patients and factors associated with it.

Methods:

In total 180 axSpA patients according to ASAS classification criteria with a new TNFi prescription in the last two weeks period were included in this observational study. Clinical data and serum samples were collected at baseline and at every 12 weeks. Serum drug levels and ADAs were measured on 12, 24, 52 and 104 weeks of treatment by ELISA in one center to avoid inter-assay variability. The development of ADA over time was investigated by using generalized estimating equations (GEE) which is a technique for longitudinal data analysis allowing the use of all available data even deviated from normality.

Results:

180 biologic naive axSpA patients (116 male, median [IQR] 44,5 [14,5] years) who started anti-TNF agents (infliximab [20%], adalimumab [27,2%], etanercept [32,2%] and golimumab [20,6%]) were included in the analysis. In comparison to baseline values BASDAI, ASDAS-CRP and CRP values were significantly decreased in third months of follow-up (Figure 1). In total 172 patients had at 12 weeks, 154 at 24, 121 at 52, and 73 at 104 week serum samples available for ADA determination. In longitudinal analysis; baseline age and TNFi type, as well as longitudinal BASDAI, ASDAS, serum CRP levels and the development of adverse events and discontinuation of the drug were found to be associated with the development of ADA. In order to determine independent association/s with the development of ADA two longitudinal multivariable models were run; (a) with ASDAS as an activity measure, (b) with BASDAI and CRP levels and produced that all the variables were independently associated with longitudinally development of anti-drug antibodies (Table 1). Antibodies to adalimumab were related with lower serum drug levels.

Conclusion:

The results of the present study with up to 2 years of follow-up, revealed that the development of ADA against TNFi therapy is associated with high disease activity, the development of adverse events and treatment discontinuation in patients with axSpA. And etanercept might be negatively associated with the development of ADA.

AB0229 A NATIONAL, MULTICENTER, SECONDARY DATA USE STUDY EVALUATING EFFICACY AND RETENTION OF FIRST-LINE BIOLOGIC TREATMENT WITH TOCILIZUMAB IN PATIENTS WITH RHEUMATOID ARTHRITIS IN REAL-LIFE SETTING FROM TURKBIO REGISTRY

Background:

Tocilizumab (TCZ) is a human anti-interleukin (IL)-6 receptor antibody approved in Turkey for the treatment of rheumatoid arthritis (RA).

Objectives:

In this study our purpose was to describe the disease activity, quality of life (QoL), and retention rate in RA patients who were prescribed TCZ as first-line biologic treatment in a real-world setting.

Methods:

Anonymized patient registry of TURKBIO was used based in a national, multicenter, and retrospective context. We conducted a search in the registry between years 2013 and 2020 and included adult RA patients who were prescribed with TCZ as their first-line biologic treatment with a post-TCZ follow-up of at least 6 months. CDAI, DAS28-(ESR), and HAQ-DI scores in 6, 12, and 24 months were obtained. Pairwise comparison was carried out for survey scores across baseline and timepoints. Subgroup analysis for route of TCZ administration was performed. EULAR response criteria were used for response evaluation. Retention of TCZ was evaluated by Kaplan-Meier analysis.

Results:

Overall,130 patients with a mean RA duration of14 years were included in the study. 87.7% of the patients were female and mean age was53 (SD; 15.0). Median duration of follow-up was 18.5 months. Majority (90.8%) of patients were given tocilizumab via intravenous route at baseline. Number of patients with ongoing TCZ treatment and follow-up at 6, 12, and 24 months were 121 (93%), 85 (65%), and 46 (35%), respectively. Remission rates at 6, 12, and 24 months per CDAI (<2.8) and DAS28-(ESR) (<2.6) scores were 61.5%, 44.6%, 30%, and 54.6%, 40.8%, 27.7%, respectively. CDAI, DAS28-(ESR) and HAQ-DI survey scores significantly improved at 6, 12 and 26 months, respectively (p<0.001) (Table 1) in both IV and SC TCZ subgroups. At 6, 12 and 24months 74.8%, 82.5% and 86.4% of patients achieved a EULAR good response respectively. Twenty-three patients (17.6%) discontinued TCZ at 24 months. Of these, 19 patients discontinued due to unsatisfactory response. Retention rates of TCZ at 6, 12, and 24 months were 93%, 84.3%, and 72.2%, respectively (Figure 1).

Conclusion:

TCZ as a first-line biologic treatment was found to be clinically effective in this real-world study with a high retention rate. These results are in line with the results gathered from previous TCZ controlled and real-life studies in which TCZ was found clinically safe and effective.

AB0893-HPR TREATMENT SATISFACTION, EXPECTATIONS, PATIENT PREFERENCES, AND CHARACTERISTICS IN PATIENTS WITH RHEUMATOID ARTHRITIS (RA): TURKISH COHORT RESULTS OF THE SENSE STUDY

Background:

Suboptimal control of RA may lead to severe and progressive articular damage, loss of function, and deterioration of the quality of life (QoL).

Objectives:

To assess treatment satisfaction, sociodemographic, clinical, health care resource utilization, and QoL characteristics of patients with sub-optimally controlled RA and treated with conventional synthetic and/or biologic DMARDs.

Methods:

This study was an international, multicenter, cross-sectional, non-interventional study. Adult RA patients with moderate to severe disease activity (DAS28>3.2) were enrolled. Patient satisfaction was evaluated with Treatment Satisfaction Questionnaire for Medication (TSQM, version 1.4) with a scale ranging from 0 (indicating poor satisfaction) to 100 (indicating perfect satisfaction). Patients were questioned regarding treatment adherence, patient preferences, and expectations. Workability was evaluated using Work Productivity and Activity Impairment Questionnaire-Rheumatoid Arthritis (WPAI-RA, version 2.0). Short Form 36 (V2) survey were performed to all patients.

Results:

One hundred sixty-four patients were included in the study and most (78.0%) were female. The median age was 57.0 years, ranging between 22.0 and 84.0 years. Half of the patients (50.6%) were primary school graduates and 6.1% were unemployed due to RA and seeking work. Median time since RA diagnosis was 8.0 years and mean (±SD) DAS28-CRP score was 4.8 (±1.0). Mean total activity impairment was 54.9% (±27.4). In the past 3 months from enrollment, the mean number of healthcare professional and emergency room visits were 1.8 (±1.1) and 1.8 (±1.3), respectively. Mean number and length of hospitalizations in the previous 3 months were 1.1 (±0.3) times and 8.3 (±7.2) days, respectively. Mean TSQM scores were 53.5 (±21.4) for effectiveness, 86.0 (±26.7) for side effects, 67.8 (±16.5) for convenience, and 57.7 (±22.0) for global satisfaction. The leading expectation was ‘lasting relief of RA symptoms’ (mean score: 5.8). Preferred time until the effect of onset was ‘up to 1 week’ for 76.2% of the patients. Most of the patients (57.9%) preferred oral administrations and the most preferred frequency of administration was ‘once per day’ (46.3%). Mean physical and mental component summary scores for Short Form 36 (V2) survey were 37.9 (±8.3) and 40.1 (±10.7).

Conclusion:

Two-thirds of the patients with RA who have suboptimal responses are not satisfied with their treatments. Moreover, oral and once-daily treatment approaches stand out in patient preferences. Finally, suboptimal control leads to deterioration in clinical characteristics, workability, and QoL of patients with RA.

AB0479 LONGTERM RETENTION RATE OF CERTOLIZUMAB PEGOL IN AXIAL SPONDYLOARTHRITIS IS HIGHER: DATA FROM TURKBIO

Background:

Choosing the best treatment strategy for a patient is one of the most difficult issues in modern rheumatology, as there are various factors affecting drug therapy in chronic diseases, such as efficacy, safety, and compliance. Physicians take care of long-term retention rate and responses for discontinuation of candidate drug.

Objectives:

The purpose of this study to assess the drug survival of certolizumab pegol (CZP) in patients with axial spondyloarthritis (ax-SpA) and to identify the predictors and reasons for discontinuation.

Methods:

Data on patient characteristics, demographics, diagnosis, duration of disease, treatment and outcomes have been collected since 2011 in Turkish Biologic (TURKBIO) Registry. By the end of December 2020, 410 ax-SpA patients received CZP and were included. Kaplan Meier plot was used for drug survival analysis. Cox regression analysis was performed to evaluate the predictor associated with drug survival.

Results:

During the median 54 months follow-up, 92 (22.4%) patients discontinued the CZP treatment. The reasons for discontinuation: ineffectivity was 58.7% (n=54), adverse events was 6.5%, pregnancy was 3.3% and surgery was 4.3%. The baseline characteristics of patients continue with CZP and discontinuation due to ineffectiveness were shown in the Table 1. Patients who discontinued CZP had higher HAQ, BASFI and BASDAI values. Moreover, they were more co-treated with NSAIDs and csDMARDs. At the month 36, retention rate of CZP was 71.5% in patients with ax-SpA (Figure 1).

Conclusion:

Real life experience from this nationwide TURKBIO registry show higher long-term retention rate of CZP in ax-SpA. Higher baseline disease activity and functional limitation predict discontinuation of CZP. Adding NSAIDs and csDMARDs to the treatment of the patient with poor prognosis cannot increase retention rates.

Assessment of the effects of loneliness, perceived social support, and depression on medication adherence in patients with ankylosing spondylitis

PURPOSE

This study aims to investigate the effects of loneliness, perceived social support, and depression on medication adherence of patients with ankylosing spondylitis (AS).

DESIGN AND METHODS

This cross-sectional study was conducted with 119 AS patients. Data were collected using the Morisky-Green-Levine Medication Adherence Scale, the UCLA Loneliness Scale (ULS), the Multidimensional Scale of Perceived Social Support (MSPSS), and the Beck Depression Inventory (BDI).

FINDINGS

Nonadherent patients were younger (P = .033), scored higher on the ULS (P = .015), and BDI (P = .024) scales, and lower on the MSPSS scale (P = .039) and on family support (P = .002).

PRACTICAL IMPLICATIONS

The biopsychosocial aspects of patients with AS should be managed holistically to improve their medication adherence.

Incidentally Detected Gastric Gastrointestinal Stromal Tumor during Living Donor Liver Transplant Surgery for Hepatocellular Carcinoma: The First Two Cases

Coexistence of hepatocellular carcinoma and gastrointestinal stromal tumor is rare. In this case series, we aimed to present an unusual coincidence of a gastrointestinal stromal tumor and hepatocellular carcinoma in patients who underwent living donor liver transplantation for hepatocellular carcinoma who had an incidental gastric gastrointestinal tumor which was detected intraoperatively.

Serum NO, S100B, NSE concentrations in migraine and their relationship

INTRODUCTION

Migraine pathogenesis still remains uncertain. Studies have found contradictory results regarding NO, S100B and NSE parameters in migraine patients. Therefore, in our study, we aimed to measure NO, S100B and NSE concentrations in migraine patients, compare them with the control group and find the relationship between these parameters.

MATERIALS AND METHODS

Fifty-two patients (35 women and 17 men) diagnosed with migraine according to the International Headache Classification II criteria were included in the study. 30 healthy participants without any history of disease were included in the control group. Serum NO, S100B and NSE levels were determined in all participants.

RESULTS

It was found that NO, S100B parameters increased compared to the control group, and NSE parameter decreased compared to the control group in the migraine patients participating in this study (p = 0,004, p = 0,002, p = 0,000) It was found that there was a moderate positive linear correlation between serum S100B and NSE in the migraine patients in our study (r = 442, p = 0.011).

CONCLUSION

In our study, the fact that there was a statistically significant difference in the NO, S100b and NSE parameters of migraine and control group patients indicates that these molecules can be effective in the pathogenesisof migraine. The moderate positive linear correlation found between serum S100B and NSE in migraine patients in our study demonstrates that these molecules together can be effective in the pathogenesis.
