Recurrent Cushing's Disease in Adults: Predictors and Long-Term Follow-Up.

Cushing's disease (CD) is characterized by endogenous hypercortisolism that is associated with increased mortality and morbidity. Due to high recurrence rates in CD, the determination of high-risk patients is of paramount importance. In this study, we aimed to determine recurrence rates and clinical, laboratory, and histological predictors of recurrence in a high volume single-center. This retrospective study included 273 CD patients operated in a single pituitary center between 1997 and 2020. The patients with early postoperative remission were further grouped according to recurrence status (recurrent and sustained remission groups). Demographic, radiologic, laboratory, pathologic, and follow-up clinical data of the patients were analyzed and compared between groups. The recurrence rate was 9.6% in the first 5 years; however, the overall recurrence rate was 14.2% in this study. Higher preoperative basal ACTH levels were significantly correlated with CD recurrence even with ACTH levels adjusted for tumor size, Ki-67 levels, and tumoral invasion. Recurrence rates were significantly higher in patients with ACTH levels higher than 55 pg/ml, tumor diameter>9.5 mm, and if adrenal axis recovery was before 6 months. The severity of hypercortisolism, morbidities, and demographic factors except age were not predictive factors of recurrence. Based on our study data, younger age at diagnosis, a diagnosis of osteoporosis, higher preoperative ACTH levels, larger tumor size, invasive behavior, higher Ki 67 index, and early recovery of the adrenal axis during the postoperative period attracted attention as potential predictors of recurrent disease.

Resveratrol prevents ovariectomy-induced bone quality deterioration by improving the microarchitectural and biophysicochemical properties of bone.

INTRODUCTION: Osteoporosis is a major health problem that is very common worldwide and is characterized by both low bone density and deterioration in bone quality. New treatment options without side effects have become an active area of research in recent years. This study was designed to investigate the preventive effects of resveratrol on bone quality deterioration caused by ovariectomy. MATERIALS AND METHODS: Sixty rats were randomly divided into five groups (12 animals per group): Control, Sham-operated (SHAM), ovariectomized (OVX), OVX + Resveratrol-40 mg/kg/day (OVX + Res40), OVX + Resveratrol-80 mg/kg/day (OVX + Res80). Resveratrol was administered by oral gavage (40 and 80 mg/kg/day) for ten weeks. Micro-CT measurements, biomechanical testing, Raman spectroscopy analysis, and RT-PCR analysis were performed. ALP, OCN, TAS, and TOS levels were also measured from blood serum. RESULTS: Bone strength, bone volume/total volume, trabecular volume, and trabecular thickness were higher in the OVX + RES-80 group than in the OVX group. Resveratrol increased osteogenic differentiation, as the expression of osteogenic markers ALP, Col1A1, Runx2, OPG, OCN increased in both OVX + RES-80 and OVX + RES-40 groups compared to the OVX group. 80 mg/kg/day resveratrol administration decreased the levels of ALP, OCN and TOS in ovariectomized rats. Raman spectroscopy findings showed a preventive effect of resveratrol administration against ovariectomy-induced deterioration in biophysiochemical properties of bone tissue. CONCLUSION: This study revealed that administration of different doses of 80 mg/kg/day and 40 mg/kg/day of resveratrol had protective effects on bone quality deterioration caused by ovariectomy.

Sensitivity of the amide I band to matrix manipulation in bone: a Raman micro-spectroscopy and spatially offset Raman spectroscopy study.

The fracture resistance of bone arises from the hierarchical arrangement of minerals, collagen fibrils (i.e., cross-linked triple helices of α1 and α2 collagen I chains), non-collagenous proteins, and water. Raman spectroscopy (RS) is not only sensitive to the relative fractions of these constituents, but also to the secondary structure of bone proteins. To assess the ability of RS to detect differences in the protein structure, we quantified the effect of sequentially autoclaving (AC) human cortical bone at 100 °C (∼34.47 kPa) and then at 120 °C (∼117.21 kPa) on the amide I band using a commercial Raman micro-spectroscopy (µRS) instrument and custom spatially offset RS (SORS) instrument in which rings of collection fiber optics are offset from the central excitation fiber optics within a hand-held, cylindrical probe. Being clinically viable, measurements by SORS involved collecting Raman spectra of cadaveric femur mid-shafts (5 male & 5 female donors) through layers of a tissue mimic. Otherwise, µRS and SORS measurements were acquired directly from each bone. AC-related changes in the helical status of collagen I were assessed using amide I sub-peak ratios (intensity, I, at ∼1670 cm-1 relative to intensities at ∼1610 cm-1 and ∼1640 cm-1). The autoclaving manipulation significantly decreased the selected amide I sub-peak ratios as well as shifted peaks at ∼1605 cm-1 (µRS), ∼1636 cm-1 (SORS) and ∼1667 cm-1 in both µRS and SORS. Compared to µRS, SORS detected more significant differences in the amide I sub-peak ratios when the fiber optic probe was directly applied to bone. SORS also detected AC-related decreases in I1670/I1610 and I1670/I1640 when spectra were acquired through layers of the tissue mimic with a thickness ≤2 mm by the 7 mm offset ring, but not with the 5 mm or 6 mm offset ring. Overall, the SORS instrument was more sensitive than the conventional µRS instrument to pressure- and temperature-related changes in the organic matrix that affect the fracture resistance of bone, but SORS analysis of the amide I band is limited to an overlying thickness layer of 2 mm.

Potential Protective Effects of Ruta Chalepensis L. Extracts Against Gentamicin-Induced Nephrotoxicity via Reduction on Apoptotic, DNA Damage and Oxidative Stress Markers in Mice.

In this study, the protective effects of Ruta chalepensis L. extracts on the extent of tissue damage in gentamicin-induced nephrotoxicity have been investigated. Ruta chalepensis L. extracts were prepared by subcritical water and ultrasound-assisted organic solvent extraction methods. Protective activity of Ruta chalepensis L. extracts on Gentamicin-induced nephrotoxicity is investigated by apoptotic, DNA damage, oxidative stress markers and evaluating histopathological in kidney tissue of mice. Gentamicin significantly increased Caspase-3 and -8 activities, NO levels, serum creatinine and BUN, while 8-OHdG and MDA levels were significantly decreased with Ruta chalepensis L. extract treatment. In addition, Ruta chalepensis L. extracts treatment significantly increased CAT and SOD activities. Histopathological alterations in Gentamicin group were significantly diminished by application of Ruta chalepensis L. extracts. These results suggest that treatment with Ruta chalepensis L. extracts may ameliorate renal dysfunction and structural damage through the reduction of oxidative stress and apoptosis in the kidney.

Anterior segment complications after dexamethasone implantations:real world data.

PURPOSE: We aim to contribute to the literature in terms of treatment safety with our real world data by examining the anterior segment complications and follow-up results of patients who underwent dexamethasone implants in our clinic. METHODS: The records of patients treated with at least one intravitreal dexamethasone implant for various retinal diseases: diabetic macular edema (265 eyes), central retinal vein occlusion (45 eyes), retinal vein branch occlusion (91 eyes), postoperative cystoid macular edema (18 eyes), non-infectious uveitis (37 eyes) and other (14 eyes) between July 2013 and April 2020 were reviewed. RESULTS: After 925 injections were applied to 470 eyes of a total of 383 patients, the eyes were controlled during a mean follow-up of 24 months. No complications were detected in 328 eyes. Intraocular pressure (IOP) above 25 mmHg was detected in 97 eyes (20.6%) that had no previous history of ocular hypertension. Of these 97 eyes, 71 (73.1%) eyes with increased IOP were treated with topical monotherapy, 26 (26.8%) eyes were treated with topical combined therapy and 1 (1.03%) patient had glaucoma surgery. Cataracts requiring surgical intervention developed in 55 (%21.73) of 253 phakic eyes. Three patients have anterior chamber dislocation of dexamethasone, 1 patient was hospitalized with sterile endophthalmitis on the 7th day after the injection, and pars plana vitrectomy was performed. CONCLUSION: This study is the first long-term follow-up study in our country evaluating the safety of dexamethasone implant injections in various retinal diseases and presenting the first real world data. Cataract progression and increased IOP were found to be the most common side effects. We observed that the patient's diagnosis did not cause a statistically significant change in the observation of side effects. As a result of our findings, close follow-up of IOP after the injection of dexamethasone implants would be appropriate.

Changes in retinal vessel and retinal layer thickness after cross-linking in keratoconus via swept-source OCT angiography.

PURPOSE: To analyze the postoperative foveal avascular zone (FAZ) area, superficial capillary plexus (SCP), deep capillary plexus (DCP) vascular densities (VD), and retinal layers after cross-linking (CXL) for keratoconus treatment. METHODS: Twenty-seven eyes with cross-linking treatment for keratoconus were included in the study. Foveal avascular zone (FAZ) area, SCP VD, DCP VD, and retinal layers were evaluated by using optical coherence tomography angiography (OCTA). OCTA measurements were made at preoperative, first week, and first and sixth months after the surgery. In addition, corneal topography measurements were also made. RESULTS: Although there was a decrease in corneal thickness in the follow-up of the patients, there was no significant difference in axial length and anterior chamber depth. There was no significant difference in full retinal thickness in the foveal and parafoveal areas. While there was a significant increase in retinal nerve fiber layer (RNFL) thickness in the foveal area (p = 0.032, p = 0.015, p = 0.017; preoperative values compared to first week, first month, and sixth month respectively), there was a decrease in ganglion cell layer (GCL) thickness in the parafoveal area in the postoperative sixth month (p = 0.028). There was no difference in FAZ measurements. In the parafoveal area, a decrease was observed in SCP VD in the sixth-month control (p = 0.019). There was a significant increase in DCP VD in the foveal area (p = 0.008, p = 0.043, p = 0.040). The preoperative mean CDVA (corrected distance visual acuity) was 0.37 ± 0.16 logMAR and postoperative sixth month mean CDVA was 0.39 ± 0.15. There was no significant difference in visual acuity (p = 0.71). CONCLUSION: Keratoconus patients successfully treated with CXL had significant changes in retinal layers and vessel density in the superficial and deep retinal plexus.

Compositional assessment of bone by Raman spectroscopy.

Raman spectroscopy (RS) is used to analyze the physiochemical properties of bone because it is non-destructive and requires minimal sample preparation. With over two decades of research involving measurements of mineral-to-matrix ratio, type-B carbonate substitution, crystallinity, and other compositional characteristics of the bone matrix by RS, there are multiple methods to acquire Raman signals from bone, to process those signals, and to determine peak ratios including sub-peak ratios as well as the full-width at half maximum of the most prominent Raman peak, which is nu1 phosphate (ν1PO4). Selecting which methods to use is not always clear. Herein, we describe the components of RS instruments and how they influence the quality of Raman spectra acquired from bone because signal-to-noise of the acquisition and the accompanying background fluorescence dictate the pre-processing of the Raman spectra. We also describe common methods and challenges in preparing acquired spectra for the determination of matrix properties of bone. This article also serves to provide guidance for the analysis of bone by RS with examples of how methods for pre-processing the Raman signals and for determining properties of bone composition affect RS sensitivity to potential differences between experimental groups. Attention is also given to deconvolution methods that are used to ascertain sub-peak ratios of the amide I band as a way to assess characteristics of collagen type I. We provide suggestions and recommendations on the application of RS to bone with the goal of improving reproducibility across studies and solidify RS as a valuable technique in the field of bone research.

Evaluation of painkillers according to the principles of rational drug use in patients registered to a family medicine unit.

AIMS: We aimed to evaluate knowledge, attitudes and usage of the painkillers within the framework of rational drug use. METHODS: This study was conducted in a family medicine unit with a questionnaire consists of 27 questions. RESULTS: Total of 506 patients participated in the study. The number of people who used pain medication every day was 29 (5.7%) and paracetamol was the most common analgesic (51.1%). The use of painkillers was more common in women and amongst the patients over 65 years of age. The rate of those who preferred painkillers in the form of pills was higher in married patients and the singles preferred injectables (P = .004). Inappropriate use of painkillers was much more prominent in nonsteroidal antiinflammatory drug users (P < .05). CONCLUSION: Demographic features and disease characteristics were the notable factors that affected painkillers selection and the level of knowledge about them.

ECHOCARDIOGRAPHIC PREDICTORS OF THE EARLY POSTOPERATIVE PERIOD IN PATIENTS AFTER CORONARY ARTERY BYPASS GRAFT SURGERY.

OBJECTIVE: The aim: The purpose of the present research was to study the results of coronary artery bypass graft (CABG) surgery depending on the degree of left ventricular ejection fraction (LVEF) reduction with the aim to identify additional echocardiographic predictors of the early postoperative period. PATIENTS AND METHODS: Materials and methods: Were fixed, the results of CABG in 97 patients operated on in the "Bikard" private clinic from March 2016 to December 2018 were the material of the research. All patients underwent CABG surgery under cardiopulmonary bypass and cardioplegia, and in the preoperative period underwent echocardiographic examination according to the standard technique on the Vivid 7 machine. Patients, in dependent of the LVEF, were divided into 3 groups: group 1 35 people (LVEF < 40%), group 2 32 people ( 40% < LVEF < 50%), group 3 30 people (LVEF > 50%). RESULTS: Results: Our studies showed that the most important echocardiographic predictors of a complicated development of the disease in the early postoperative period, in addition to LVEF of the heart, can be the size of the left ventricle and left atrial, the presence and severity of mitral regurgitation and diastolic dysfunction of the left ventricle of the heart. CONCLUSION: Conclusions: Comprehensive measurement of these echocardiographic parameters will allow more accurately predict the results of coronary artery bypass grafting in the early postoperative period.

Comparison of P-Wave Duration and Dispersion in Mitral Valve Replacement Surgery Via Right Atrial Transseptal or Left Atrial Approach in Rheumatic Mitral Stenosis Patients.

BACKGROUND: Predisposition to atrial fibrillation in mitral valve surgery has been well demonstrated. The changes in electrocardiographic parameters (Pmax, Pmin and P-wave dispersion) related to AF risk are unknown. We aimed to document the relationship between electrocardiographic changes and mitral valve replacement through right or left atrial surgical approaches. METHODS: We retrospectively studied 154 patients, who underwent mitral valve replacement surgery from 2008 to 2018. Seventy-nine patients were operated with right atriotomy and transseptal approach (Group 1), and 75 patents were operated with left atriotomy (Group 2). ECGs obtained at hospital admittance and postoperatively at 24 hours were blindly analyzed. RESULTS: Preoperative demographic characteristics were similar. Pmax, Pmin and P-wave dispersion were similar preoperatively. All parameters increased in both groups compared with the preoperative values (P < .05). Postoperative Pmax, Pmin and P-wave dispersion all were statistically significantly higher with the right atrial approach (P < .05). Postoperative AF also was more common in Group 1 (P < .05). CONCLUSION: Right atrial approach may lead to higher P-wave changes and atrial arrhythmias. This may be due to more extensive surgical disruption. The changes in atrial anatomic structure can increase atrial arrhythmic propensity and can cause atrial fibrillation.

The Role of Matrix Composition in the Mechanical Behavior of Bone.

PURPOSE OF REVIEW: While thinning of the cortices or trabeculae weakens bone, age-related changes in matrix composition also lower fracture resistance. This review summarizes how the organic matrix, mineral phase, and water compartments influence the mechanical behavior of bone, thereby identifying characteristics important to fracture risk. RECENT FINDINGS: In the synthesis of the organic matrix, tropocollagen experiences various post-translational modifications that facilitate a highly organized fibril of collagen I with a preferred orientation giving bone extensibility and several toughening mechanisms. Being a ceramic, mineral is brittle but increases the strength of bone as its content within the organic matrix increases. With time, hydroxyapatite-like crystals experience carbonate substitutions, the consequence of which remains to be understood. Water participates in hydrogen bonding with organic matrix and in electrostatic attractions with mineral phase, thereby providing stability to collagen-mineral interface and ductility to bone. Clinical tools sensitive to age- and disease-related changes in matrix composition that the affect mechanical behavior of bone could potentially improve fracture risk assessment.

Molecular cytogenetic analysis reveals the existence of two independent neo-XY sex chromosome systems in Anatolian Pamphagidae grasshoppers.

BACKGROUND: Neo-XY sex chromosome determination is a rare event in short horned grasshoppers, but it appears with unusual frequency in the Pamphagidae family. The neo-Y chromosomes found in several species appear to have undergone heterochromatinization and degradation, but this subject needs to be analyzed in other Pamphagidae species. We perform here karyotyping and molecular cytogenetic analyses in 12 Pamphagidae species from the center of biodiversity of this group in the previously-unstudied Anatolian plateau. RESULTS: The basal karyotype for the Pamphagidae family, consisting of 18 acrocentric autosomes and an acrocentric X chromosome (2n♂ = 19, X0; 2n♀ = 20, XX), was found only in G. adaliae. The karyotype of all other studied species consisted of 16 acrocentric autosomes and a neo-XY sex chromosome system (2n♂♀ = 18, neo-XX♀/neo-XY♂). Two different types of neo-Y chromosomes were found. One of them was typical for three species of the Glyphotmethis genus, and showed a neo-Y chromosome being similar in size to the XR arm of the neo-X, with the addition of two small subproximal interstitial C-blocks. The second type of the neo-Y chromosome was smaller and more heterochromatinized than the XR arm, and was typical for all Nocarodeini species studied. The chromosome distribution of C-positive regions and clusters of ribosomal DNA (rDNA) and telomeric repeats yielded additional information on evolution of these neo-XY systems. CONCLUSION: Most Pamphagidae species in the Anatolian region were found to have neo-XY sex chromosome systems, belonging to two different evolutionary lineages, marked by independent X-autosome fusion events occurred within the Trinchinae and Pamphaginae subfamilies. The high density of species carrying neo-XY systems in the Anatolian region, and the different evolutionary stage for the two lineages found, one being older than the other, indicates that this region has a long history of neo-XY sex chromosome formation.

Effects of losartan treatment on the physicochemical properties of diabetic rat bone.

Inhibitors of the renin-angiotensin system used to treat several diseases have also been shown to be effective on bone tissue, suggesting that angiotensin-converting enzyme inhibitors and angiotensin receptor blockers may reduce fracture risk. The present study investigated the effects of losartan on the physicochemical and biomechanical properties of diabetic rat bone. Losartan (5 mg/kg/day) was administered via oral gavage for 12 weeks. Bone mineral density (BMD) was measured using dual-energy X-ray absorptiometry. Whole femurs were tested under tension to evaluate the biomechanical properties of bone. The physicochemical properties of bone were analyzed by Fourier transform infrared spectroscopy. Although losartan did not recover decreases in the BMD of diabetic bone, it recovered the physicochemical (mineral and collagen matrix) properties of diabetic rat bone. Furthermore, losartan also recovered ultimate tensile strength of diabetic rat femurs. Losartan, an angiotensin II type 1 receptor blocker, has a therapeutic effect on the physicochemical properties of diabetic bone resulting in improvement of bone strength at the material level. Therefore, specific inhibition of this pathway at the receptor level shows potential as a therapeutic target for diabetic patients suffering from bone diseases such as osteopenia.

Miniscrew biomechanics: Guidelines for the use of rigid indirect anchorage mechanics.

Indirect anchorage is an established form of anchorage provided by orthodontic miniscrews. Although there are different ways to set up the mechanics, rigid indirect anchorage offers the greatest biomechanical versatility but is more difficult to install than conventional, nonrigid indirect anchorage or direct anchorage. The purpose of this article was to introduce readers to the concept of rigid indirect anchorage and provide guidelines as to its use.

Normocalcemic hyperparathyroidism is associated with complications similar to those of hypercalcemic hyperparathyroidism.

Normocalcemic primary hyperparathyroidism (NC-PHPT) is a variant of hyperparathyroidism, characterized by normal serum calcium levels, high parathyroid hormone (PTH) and normal 25-OH vitamin D status. The present study aimed to compare complications related to hyperparathyroidism in patients with NC-PHPT and hypercalcemic PHPT (HC-PHPT). We retrospectively evaluated the records of 307 PHPT patients between January 2010 and March 2013. We excluded patients with impaired renal function and liver failure. All patients underwent a biochemical and hormonal examination including serum glucose, albumin, total calcium, phosphorus, creatinine, lipoproteins, PTH and 25-OH vitamin D. Nephrolithiasis and bone mineral density were documented based on a review of the medical records. The study population consisted of 36 (12 %) males and 271 (88 %) females with a mean age of 53.3 ± 9.5 years (29-70 years). Twenty-three of the patients were diagnosed with NC-PHPT (group 1) and 284 were diagnosed with HC-PHPT (group 2). There were no significant differences in terms of age, gender, prevalence of hypertension, low bone mineral density and kidney stones between the groups. The mean thyroid-stimulating hormone (TSH) and low-density lipoprotein (LDL) levels were significantly higher in group 1 than in group 2. Our study found that patients with NC-PHPT have similar several complications as patients with HC-PHPT. NC-PHPT patients have higher TSH levels despite being within the normal range, and higher LDL-C levels than patients with HC-PHPT. However, this relationship needs to be clarified in future studies with larger cohorts.

Increased Serum Levels of IL-28 and IL-29 and the Protective Effect of IL28B rs8099917 Polymorphism in Patients with Hashimoto's Thyroiditis.

Hashimoto's thyroiditis (HT) is thought to result from decreased T helper type 2 (Th2) responses, leading to the progressive destruction of thyrocytes. IFN-λ1, -λ2, and -λ3 (also known as IL-29, IL-28A, and IL-28B, respectively) are recently described members of the IFN-λ family and have been shown to decrease the production of Th2 cytokines in vitro. However, the role and mechanism of IFN-λ1 in HT remain unknown. The purpose of this study was to examine whether IL29 and IL28B gene polymorphisms are susceptibility genes for the development of HT. Also, we investigated the effects of IL-29 and IL-28 serum levels in the pathogenesis of HT. Using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method, single-nucleotide polymorphisms (SNPs) of IL28B rs8099917 (IL28 G/T) and IL29 rs30461 (IL29 T/C) were studied in 99 patients with HT and 100 healthy controls. Considering the allelic distribution of the IL28 G/T polymorphism, a higher frequency of the G allele was observed in the control group versus the HT group. Thus, it was suggested that the G allele may be protective against HT pathogenesis (OR = 0.388, 95% CI = 0.217-0.693; p = 0.001). Our findings also demonstrated that there was a statistically significant difference in serum IL-28 and IL-29 levels between case and control groups (p < 0.001). Increased serum levels of IL-28 and IL-29 were found in patients with HT. However, we did not find a relationship between the IL29 gene polymorphism and HT. In conclusion, the IL28B gene polymorphism and serum IL-28 and IL-29 levels seem to play a role in the pathogenesis of HT.

Assessment of Mean Platelet Volume and its Effect on Disease Control in Patients with Acromegaly.

BACKGROUND: Morbidity and mortality rates due to cardiovascular diseases are more common in acromegalic patients than the healthy population. Platelets play a significant role in both the onset and progression of clotting which then cause the development of atherosclerotic plaques. Increased mean platelet volume (MPV) is an indicator of platelet activation and known as an independent risk factor for atherosclerotic processes. The aim of this study was to compare MPV levels between acromegalic and non-acromegalic patients. METHODS: The data of 56 acromegalic patients and 72 controls matched for age, gender, and the presence of diabetes were retrospectively reviewed. RESULTS: MPV levels were found to be higher in acromegalic patients compared to controls (8.82 ± 1.17 fL and 7.74 ± 0.87 fL, respectively, p < 0.001). Acromegalic patients were also classified according to their status of remission (a total of 27 patients were in remission and 29 patients were not in remission). Both age and gender were similar between the groups (p = 0.145 and p = 0.616, respectively). MPV levels at the time of diagnosis and after six months of treatment (p = 0.555 and p = 0.917, respectively) were not statistically significant. CONCLUSIONS: Our results suggest that MPV levels are higher in acromegalic patients than the controls until the early stages of treatment, independent of diabetes. Therefore, MPV levels may be an important determinant of acromegalic patients.

Psychiatric symptoms in ankylosing spondylitis: their relationship with disease activity, functional capacity, pain and fatigue.

OBJECTIVES: The aim of this study is to evaluate psychiatric symptoms in patients with ankylosing spondylitis (AS) and to investigate the relationship of the disease activity, functional capacity, pain, and fatigue with psychiatric symptoms. METHODS: Eighty AS patients and 80 healthy controls were included in the study. Spinal pain by visual analog scale (pain VAS-rest), disease activity by Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), functional capacity by Bath Ankylosing Spondylitis Functional Index (BASFI), and fatigue by Multidimensional Assessment of Fatigue (MAF) were assessed in patients. Psychiatric symptoms were measured using the Symptom Checklist-90-R (SCL-90 R), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Pittsburgh Sleep Quality Index (PSQI) and Rosenberg Self-Esteem Scale (RSES). RESULTS: SCL-90-R total and all subscale scores (except interpersonal sensitivity and psychoticism) and BDI scores were significantly higher in the AS group compared to control group. PSQI total and all subscale scores were significantly higher in the AS group. State anxiety scale score was significantly higher and RSES score was significantly lower in the AS group. Psychiatric symptoms (except Rosenberg Self-Esteem score) were significantly correlated with BASDAI, BASFI, pain VAS rest, and MAF scores. CONCLUSION: Psychiatric symptoms are often seen in patients with AS. Disease activity, functional capacity, pain and fatigue were correlated with psychiatric symptoms but self-esteem was not. Therefore, psychiatric symptoms should be taken into consideration in the management of AS.
