ABSTRACT

Purpose@#To investigate the long-term clinical outcomes of transplanted amniotic membrane in patients who underwent permanent amniotic membrane transplantation (P-AMT) on cornea. @*Methods@#From April 2014 to March 2021, medical records and digital photographs of 68 patients (72 eyes) who underwent P-AMT were analyzed retrospectively. The duration of complete re-epithelization of cornea and wearing therapeutic contact lense (T-lens) after surgery were investigated, the size of preserved amniotic membrane (AM) excluding the melted portion was analyzed using the Image J program every year up to 6 years after surgery, and it was compared by dividing into a single-layer group and a double-layer group. In addition, when the AM melts, the cause, time, and related factors of melting were analyzed. @*Results@#The average duration to complete re-epithelialization after surgery was 12.2 ± 11.0 days, and T-lens were worn on average up to 8.7 ± 8.5 months after surgery. In total group, the average ratio of preserved AM annually up to 6 years after surgery was 94.9%, 94.3%, 97.8%, 96.4%, 95.8%, 91.6% respectively, and there was no significant difference between the single-layer group and the double-layer group. AM melting appeared in 38.9% (28 eyes) of the total group, and melting was first observed on average 16.4 ± 17.2 months after surgery. The formation and rupture of bullae was the most common cause of melting at 71.4% (20 eyes), and there were no statistically significant related factors involved in the formation of bullae. @*Conclusions@#In the case of P-AMT performed in various diseases of the cornea, the transplanted AM is partially melt but considered to be well preserved up to 6 years after surgery to form a stable ocular surface.

ABSTRACT

Objective@#Although nonsteroidal anti-inflammatory drugs (NSAIDs) are the first-line treatment for ankylosing spondylitis (AS), their effect on kidney function remains unclear. This longitudinal study investigated the correlation between long-term NSAID use and kidney function in patients with AS using electronic medical records. @*Methods@#The electronic medical records of 1,280 patients with AS collected from a single center between January 2001 and December 2018 were reviewed. The Assessment of Spondyloarthritis International Society (ASAS) NSAID Intake Score was used to determine the cumulative dose of all NSAIDs prescribed for a different time intervals. Each ASAS NSAID Intake Score was obtained for intervals of 6 months, 1 year, 2 years, 3 years, 5 years, and 10 years. The correlation between the ASAS NSAID Intake Score and final estimated glomerular filtration rate (eGFR) for each interval was investigated. @*Results@#The mean ASAS Intake Scores for 6-month, 1-year, 2-year, 3-year, 5-year, and 10-year intervals were 55.30, 49.28, 44.84, 44.14, 44.61, and 41.17, respectively. At each interval, the pearson correlation coefficients were −0.018 (95% CI: −0.031 to −0.006, p=0.004), −0.021 (95% CI: −0.039 to −0.004, p=0.018), −0.045 (95% CI: −0.071 to −0.019, p=0.001), −0.069 (95% CI: −0.102 to −0.037, p<0.001), −0.070 (95% CI: −0.114 to −0.026, p=0.002), −0.019 (95% CI: −0.099 to 0.062, p=0.645), respectively. There was a very weak negative relationship between ASAS Intake Score and eGFR at each interval. @*Conclusion@#Long-term NSAID use did not correlate with kidney function based on real-world data in patients with AS.

ABSTRACT

Background@#Corrective osteotomy is an effective surgery for correcting posture in patients with ankylosing spondylitis (AS). Despite satisfactory correction, some patients experience re-stooping during follow-up. However, there have been no studies on restooping in AS. We aimed to analyze the factors that affect re-stooping. @*Methods@#Fifty patients (50 cases) who underwent thoracolumbar corrective osteotomy for AS from March 2006 to April 2018 were analyzed. We defined re-stooping as global kyphosis that recurs after corrective osteotomy. The patients were divided into two groups based on the ratio of correction loss: non-re-stooping group (N group) and re-stooping group (R group). We analyzed the demographic data and radiological parameters, such as modified Stoke Ankylosing Spondylitis Spine Score (mSASSS), sagittal vertical axis, and various angles. We also investigated the factors affecting re-stooping by analyzing the correlation between the ratio of correction loss and various factors. @*Results@#A significant difference was seen in the change in the mSASSS from before surgery to the last follow-up between the N group (2.87 ± 3.08) and the R group (9.20 ± 5.44). In multivariate analysis, only the change in the mSASSS from before surgery to the last follow-up was significantly correlated with the ratio of correction loss. @*Conclusions@#Thoracolumbar corrective osteotomy seems to provide high satisfaction among patients with AS but can lead to re-stooping during follow-up. The change in mSASSS was related with re-stooping in the current study. We recommend active rehabilitative exercises and appropriate medication depending on the patient’s condition, which may help delay the postoperative progression of AS.

ABSTRACT

We aimed to develop evidence-based recommendations for treating axial spondylarthritis (axSpA) in Korea. The development committee was constructed, key clinical questions were determined, and the evidence was searched through online databases including MEDLINE, Embase, Cochrane, KoreaMed, and Kmbase. Systematic literature reviews were conducted, quality of evidence was determined, and draft recommendations were formulated according to the Grading of Recommendations Assessment, Development, and Evaluations methodology. Recommendations that reached 80% consensus among a voting panel were finalized. Three principles and 21 recommendations were determined. Recommendations 1 and 2 pertain to treatment strategies, regular disease status assessment, and rheumatologist-steered multidisciplinary management. Recommendations 3 and 4 strongly recommend patient education, exercise, and smoking cessation. Recommendations 5–12 address pharmacological treatment of active disease using nonsteroidal anti-inflammatory drugs, glucocorticoids, sulfasalazine, biologics, and Janus kinase inhibitors. Recommendations 13–16 address treatment in stable disease. We suggest against spa and acupuncture as therapies (Recommendation 17). Recommendations 18 and 19 pertain to total hip arthroplasty and spinal surgery. Monitoring of comorbidities and drug toxicities are recommended (Recommendations 20 and 21). Recommendations for axSpA treatment in a Korean context were developed based on comprehensive clinical questions and evidence. These are intended to guide best practice in the treatment of axSpA.

ABSTRACT

Purpose@#We investigated the clinical features and risk factors associated with the onset of uveitis in patients with ankylosing spondylitis. @*Methods@#A survey was conducted targeting patients with ankylosing spondylitis who have experienced uveitis. The questionnaire collected information on demographic characteristics, clinical features, and lifestyle-related risk factors for uveitis including stress, sleep quality, rest periods, eating habits, and intake of caffeine, alcohol, and tobacco. Respondents were asked to recall their condition at the time of their most recent uveitis flare-up and rate it on a 5-point scale (1 = good to 5 = bad). @*Results@#The study included 47 patients with ankylosing spondylitis; the average age was 40.0 years, 68.1% were male, and 89.4% tested positive for human leukocyte antigen (HLA)-B27. The average treatment duration for uveitis was 5.2 weeks, with an average recurrence rate of 4.5 times. The most common symptom at the time of uveitis was eye redness (87.2%). The average scores for the surveyed risk factors were as follows: stress, 4.1 points; sleep, 3.1 points; rest, 3.4 points; eating habits, 2.9 points; caffeine intake, 3.3 points; alcohol intake, 2.4 points; and smoking, 2.5 points. No significant correlation was found between age, uveitis treatment duration, number of recurrences, and any of the surveyed scores. @*Conclusions@#Patients with ankylosing spondylitis appeared to experience higher levels of stress during episodes of uveitis; however, further investigation is needed.

ABSTRACT

Objective@#Bone morphogenetic protein receptor type 2 (BMPR2) has been associated with radiographic changes in ankylosing spondylitis (AS), but further characterization of the cellular signaling pathway in osteoprogenitor (OP) is not clearly understood.The aim of this study was to investigate the expression of BMPR2 and bone morphogenetic protein 2 (BMP2)-mediated responsibility in AS. @*Methods@#We collected 10 healthy control (HC) and 14 AS-OPs derived from facet joints. Subsequently, we then conducted RNA sequencing with two samples per group and selected BMP-related genes. Facet joint tissues and derived primary OPs were evaluated by validation of selected RNA sequencing data, immunohistochemistry, and comparison of osteogenic differentiation potential. @*Results@#Based on RNA-sequencing analysis, we found that BMPR2 expression is higher in AS-OPs compared to in HC-OPs. We also validated the increased BMPR2 expression in facet joint tissues with AS and its derived OPs in messenger RNA and protein levels. Additionally, primary AS-OPs showed much greater response to osteogenic differentiation induced by BMP2 and a higher capacity for smad1/5/8-induced RUNX2 expression compared to HCs. @*Conclusion@#The expression of BMPR2 was found to be significantly increased in facet joint tissues of patients with AS. These findings suggest that BMPR2 may play a role in the BMP2-mediated progression of AS.

ABSTRACT

The cervical spine plays a critical role in supporting the skull, maintaining horizontal gaze, and facilitating walking. Its unique characteristics, including the widest range of motion among spinal segments, have led to extensive research on cervical sagittal alignment. Various parameters have been proposed to evaluate cervical alignment, with studies investigating their clinical significance, correlation with symptoms, and implications for surgical interventions. Recent findings suggest that cervical sagittal alignment not only impacts the cervical spine but also influences global spine-pelvic alignment through compensatory mechanisms. This comprehensive review examines classical and new parameters of cervical sagittal alignment and considers the dynamic and muscular factors associated with it.

ABSTRACT

Purpose@#Outcome analysis of urachal cancer (UraC) is limited due to the scarcity of cases and different staging methods compared to urothelial bladder cancer (UroBC). We attempted to assess survival outcomes of UraC and compare to UroBC after stage-matched analyses. @*Materials and Methods@#Total 203 UraC patients from a multicenter database and 373 UroBC patients in single institution from 2000 to 2018 were enrolled (median follow-up, 32 months). Sheldon stage conversion to corresponding TNM staging for UraC was conducted for head-to-head comparison to UroBC. Perioperative clinical variables and pathological results were recorded. Stage-matched analyses for survival by stage were conducted. @*Results@#UraC patients were younger (mean age, 54 vs. 67 years; p < 0.001), with 163 patients (80.3%) receiving partial cystectomy and 23 patients (11.3%) radical cystectomy. UraC was more likely to harbor ≥ pT3a tumors (78.8% vs. 41.8%). While 5-year recurrence-free survival, cancer-specific survival (CSS) and overall survival were comparable between two groups (63.4%, 67%, and 62.1% in UraC and 61.5%, 75.9%, and 67.8% in UroBC, respectively), generally favorable prognosis for UraC in lower stages (pT1-2) but unfavorable outcomes in higher stages (pT4) compared to UroBC was observed, although only 5-year CSS in ≥ pT4 showed statistical significance (p=0.028). Body mass index (hazard ratio [HR], 0.929), diabetes mellitus (HR, 1.921), pathologic T category (HR, 3.846), and lymphovascular invasion (HR, 1.993) were predictors of CSS for all patients. @*Conclusion@#Despite differing histology, UraC has comparable prognosis to UroBC with relatively favorable outcome in low stages but worse prognosis in higher stages. The presented system may be useful for future grading and risk stratification of UraC.

ABSTRACT

Purpose@#This study aimed to investigate the oncologic outcomes and prognostic factors of salvage treatments in patients with recurrent oropharyngeal squamous cell carcinoma (OPSCC) after radiotherapy (RT)-based treatment. @*Materials and Methods@#A cancer registry was used to retrieve the records of 337 patients treated with definitive RT or concurrent chemoradiotherapy (CRT) from 2008 to 2018 at a single institution. The poor-responder group (PRG) was defined as patients with residual or recurrent disease after primary treatment, and the oncologic outcomes for each salvage treatment method were analyzed. In addition, prognostic indicators of recurrence-free survival (RFS) and overall survival (OS) were identified in patients who underwent salvage treatment. @*Results@#After initial (C)RT, the PRG comprised 71 of the 337 patients (21.1%): 18 patients had residual disease, and 53 had recurrence after primary treatment (mean time to recurrence 19.5 months). Of these, 63 patients received salvage treatment (surgery 57.2%, re-(C)RT 23.8%, and chemotherapy 19.0%), and the salvage success rate was 47.6% at the last follow-up. The overall 2-year OS for salvage treatments was 56.4% (60.8% for the salvage surgery group and 46.2% for the salvage re-(C)RT). Salvage surgery patients with negative resection margins had better oncologic outcomes than those with close/positive resection margins. Using multivariate analyses, locoregional recurrence and residual disease after primary surgery were associated with poor outcome after salvage treatment. In Kaplan-Meier analyses, p16 status was significantly associated with OS in the initial treatment setting but not in the salvage setting. @*Conclusion@#In recurrent OPSCC after RT-based treatment, successful salvage was achieved in 56.4% patients who had undergone salvage surgery and radiation treatment. Salvage treatment methods should be selected carefully, given recurrence site as a prognostic factor for RFS.

ABSTRACT

Purpose@#To compare and investigate the short-term clinical outcomes between 10-0 polypropylene sutured intraocular lens (IOL) scleral fixation and modified Yamane sutureless IOL scleral fixation in patients with IOL or crystalline les dislocation and aphakic state. @*Methods@#From August 2012 to May 2022, medical records were retrospectively analyzed for 43 patients with sutured scleral fixation and 40 patients with sutureless scleral fixation. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), total astigmatism, IOL astigmatism, refractive error, corneal endothelial cell density, surgical time and complications were compared before surgery, 1 week, 1 month, and 3 months after surgery. @*Results@#In the two groups, after 3 months of surgery, UCVA and BCVA improved compared to before surgery, but there was no significant difference between two groups. The absolute refractive error and total astigmatism for one week after surgery and IOL astigmatism for one week and one month after surgery were significantly lower in sutureless fixation group. There was no significant difference in postoperative corneal endothelial cell density changes between two groups, and total surgical time and IOL fixation time were measured significantly lower in sutureless fixation group. @*Conclusions@#Although modified Yamane sutureless IOL scleral fixation did not show significant improvement in visual acuity compared with conventional sutured IOL scleral fixation, sutureless fixation provided better stability of IOL in the early stages after surgery and short in the surgical time. So it can be an effective alternative to conventional sutured scleral fixation in patients with IOL or crystalline lens dislocation and aphakic state.

ABSTRACT

Purpose@#A patient with heterozygous granular corneal dystrophy type 2 (GCD2) underwent phacoemulsification with multifocal intraocular lens insertion, and complained of visual discomfort. We investigated the cause of the discomfort and visual function in this case.Case summary: A 59-year-old woman with granular opacity had slit lamp photographs taken 5 years earlier. Two years later, she underwent phacoemulsification with multifocal intraocular lens (Trifocal AT Lisa tri toric 839MP®, Carl Zeiss Meditec AG, Inc., Jena, Germany) insertion in both eyes at a local clinic. She felt very uncomfortable after the surgery, but the granular and lattice opacities due to GCD2 of her corneas remained stationary for 5 years. Her visual acuity decreased from preoperatively (preoperative: right 0.5, left 0.6; last visit: right 0.3, left 0.4). Her contrast sensitivity was also decreased and the total higher order aberration was increased (right 1.590 μm, left 1.194 μm), compared to normal range. @*Conclusions@#Multifocal intraocular lens insertion in cataract surgery can lead to severe declines in contrast sensitivity and visual acuity and increased higher-order aberration in a GCD2 patient. It may not be advisable to use multifocal intraocular lenses in a GCD2 patient.

ABSTRACT

Background@#Laminoplasty is a common and effective surgery for decompression of the spinal cord in multilevel cervical myelopathy. The midline splitting technique (MST) and the unilateral open door technique (UODT) are the two most commonly performed laminoplasty techniques with continuous debate on which is preferable. This study aimed to add light to the matter by comparing and exploring the possible causes of different outcomes. @*Methods@#A total of 101 patients who underwent laminoplasty for degenerative cervical myelopathy were included in this study.Radiographic measurements including C2–7 Cobb angle, C2–7 range of motion (ROM), Pavlov ratio of the most compressed level, and canal area with diameter were compared. Modified Japanese Orthopedic Association (mJOA) score and complications including C5 palsy, axial neck pain, hinge fractures, and spacer displacement were also compared. Statistical analysis was performed using independent samples t-test, chi-square test, Fisher’s exact test, and linear mixed model. @*Results@#C2–7 ROM, canal diameter, Pavlov ratio, and mJOA score did not demonstrate differences between the two techniques.The UODT group had greater postoperative canal expansion but had more loss of C2–7 lordosis than did the MST group. Of the complications, hinge fractures were more common in the UODT group, with more loss of C2–7 lordosis in patients with hinge fractures. On the other hand, spacer displacement occurred only in the MST group, with lesser canal expansion in patients with spacer displacement. @*Conclusions@#The two laminoplasty techniques both demonstrated effectiveness in treating patients with multilevel cervical myelopathy. However, care should be given to avoid hinge fractures and spacer displacement since both can possibly lead to unfavorable outcomes.

ABSTRACT

Purpose@#Contrast sensitivity, the ability to distinguish the relative difference in luminance of an object from its surrounding or adjacent objects, is a useful measure of visual function. In granular corneal dystrophy type 2 (GCD2), opacity of the corneal stroma causes deterioration in visual function. We compared the contrast sensitivity of GCD2 patients before and after phototherapeutic keratectomy (PTK) to evaluate the perioperative visual function in these patients. @*Methods@#This study included 22 eyes of heterozygote GCD2 patients. The visual acuity and contrast sensitivity were measured before and after PTK. The contrast sensitivity was measured in mesopic and photopic background luminances, with glare (G) levels of 0-2 (G0, G1, and G2, respectively) and spatial frequencies at 1.5, 3, 6, 12, and 18 cycles per degree (cpd). @*Results@#The contrast sensitivity increased after PTK at 1.5 and 3 cpd in mesopic and photopic conditions with G0-2 glare (p < 0.05). At 6 cpd, the contrast sensitivity increased in the mesopic condition with G1 glare, and in the photopic condition with G0-2 glare (p < 0.05). However, there was no change in contrast sensitivity at any glare level at 12 and 18 cpd after PTK. @*Conclusions@#In GCD2 patients, the contrast sensitivity increased significantly after PTK. The vision of GCD2 patients, which is decreased due to corneal opacity, is improved after PTK.

ABSTRACT

Purpose@#To compare serum selenium levels in Graves patients and non-Graves control participants and to evaluate associations between serum selenium levels and clinical features of Graves orbitopathy (GO). @*Methods@#We conducted a single-center, retrospective case-control study among 33 patients with Graves disease without GO (GD), 31 patients with diagnosed GO, and 27 unaffected healthy participants enrolled between 2013 and 2020 at Severance Hospital. We compared serum selenium concentrations between the GD, GO, and healthy control groups, and analyzed associations between serum selenium and GO patients’ clinical activity scores, severity (assessed through modified NOSPECS scores), and other clinical features using multivariate linear regression analysis. @*Results@#Mean serum selenium levels were 109.30 ± 16.39, 111.39 ± 14.04, and 126.09 ± 21.09 ng/mL in GO patients, GD patients, and healthy control participants, respectively. Mean serum selenium levels in Graves patients with and without orbitopathy were significantly lower than those in the healthy control group (p < 0.05), and mean selenium levels were slightly lower in GO than those in GD patients (p = 0.594). Serum selenium levels were significantly lower in GO patients with eyelid retraction than in patients without retraction (p = 0.038). However, serum selenium levels were not associated with clinical activity scores and modified NOSPECS scores (p = 0.241 and 0.801, respectively). @*Conclusions@#Serum selenium levels were significantly lower in Graves patients with or without GO, compared to non-Graves control participants. Selenium levels were not associated with clinical activity scores or NOSPECS scores, though we observed an association with eyelid retraction.

ABSTRACT

Background/Aims@#The study investigated the incidence of thromboembolic events (TEE) in head and neck (H&N) cancer patients who received concurrent chemoradiotherapy (CCRT) with cisplatin, and analyzed the factors affecting TEE occurrence @*Methods@#Two hundred and fifty-seven patients who started CCRT with cisplatin for H&N cancer from January 2005 to December 2019 were analyzed. @*Results@#TEE occurred in five patients, an incidence rate of 1.9%. The 2-, 4-, and 6-month cumulative incidences of TEE were 0.8%, 1.6%, and 1.9%, respectively. Khorana score was the only factor associated with TEE occurrence (p = 0.010). @*Conclusions@#The incidence of TEE in H&N cancer patients who underwent CCRT with cisplatin was relatively low when compared to other types of cancer. However, patients with a high Khorana score require more careful surveillance for possible TEE occurrence.

ABSTRACT

Purpose@#There have been few reports on comparison between sunitinib and pazopanib as first-line targeted therapy in Korean metastatic clear cell renal cell carcinoma (ccRCC). We sought to analyze the treatment trends of metastatic ccRCC by comparing the effects and adverse events of sunitinib and pazopanib. @*Materials and Methods@#Data of 357 metastatic RCC patients who received the sunitinib or pazopanib as the first-line targeted therapy from the Daegyeong Oncology Study Group database was obtained and analyzed. Among these patients, patients who only clear cell type was confirmed after needle biopsy or nephrectomy were included, and patients who underwent target therapy for less than 3 months were excluded. @*Results@#Of 251 patients who met the inclusion criteria, sunitinib and pazopanib group were identified in 156 (62%) and 95 patients (38%), respectively. Pazopanib group was older (66 years vs. 61 years, p=0.001) and more symptomatic (65% vs. 52%, p=0.037) and had more patients with Karnofsky performance status <80 (20% vs. 11%, p=0.048) and fewer number of organ metastases (p=0.004) compared to sunitinib group. There was no significant difference in disease control rate (88.5% vs. 87.3%, p=0.744), the median progression-free survival (19 months vs. 15 months, p=0.444) and overall survival (25 months vs. 19 months, p=0.721) between sunitinib and pazopanib. The most common grade 3/4 adverse events with sunitinib and pazopanib were anemia (5%) and hand-foot syndrome (3%), respectively. There was no significant difference between sunitinib and pazopanib in number of patients who experienced grade 3/4 adverse events (15% vs. 11%, p=0.275). However, there were more patients who discontinued treatment due to only adverse events in sunitinib group compared to pazopanib group (12% vs. 3%, p=0.020). @*Conclusions@#In Korean metastatic ccRCC, pazopanib tended to be used in patients with poorer health status compared to sunitinib. Sunitinib and pazopanib had no significant difference in treatment effect and survival, but pazopanib had more tolerable adverse events.

ABSTRACT

Purpose@#To report a case of Exophiala endophthalmitis after cataract surgery, which has not been reported previously in Korea.Case summary: A 70-year-old woman visited the hospital 7 days after cataract surgery in her right eye with unilateral vision impairment. At the time of the visit, visual acuity of the right eye was hand motion, and the fundus was not clearly observed due to numerous inflammatory cells with hypopyon in the anterior chamber. With an initial diagnosis of suspected bacterial endophthalmitis, vitrectomy was performed immediately with intravitreal injection of antibiotics and steroid. On day 14 after vitrectomy, inflammation in the anterior chamber and vitreous opacity worsened, and complete vitrectomy, including of the vitreous base, and removal of the intraocular lens and capsule was performed. Exophiala was detected in the biopsy specimen on day 6 after the second surgery, and the patient was discharged with a prescription for voriconazole eye drops. On day 23 after the second surgery, the best-corrected visual acuity in the right eye had improved to 1.0, and there was no evidence of endophthalmitis recurrence and no observed additional abnormal findings of the fundus until 6 months after second surgery. @*Conclusions@#In a case of fungal endophthalmitis that occurred after cataract surgery, good results were obtained by vitrectomy involving complete removal of the peripheral vitreous body, including the intraocular lens and lens capsule, which was the basis for growth of the fungus in the early stage of endophthalmitis.

ABSTRACT

Background@#To evaluate the incidence of fractures and fracture risk factors in Korean patients with polymyalgia rheumatica (PMR). @*Methods@#All PMR patients who visited a rheumatology clinic at a tertiary referral hospital between March 2005 and March 2018 were retrospectively assessed. We estimated bone mineral density (BMD) screening rate within 6 months of the first visit and classified the patients according to the performance and results of BMD screening. Incidence rates (IRs) of fractures were calculated in each group and risk factors for fractures were identified using Poisson regression analysis. @*Results@#A total of 95 PMR patients with median (interquartile range) age of 64.0 (56.0–72.0) years were included. Baseline BMD was assessed in only 55.8% of these patients (n = 53); 24 patients with osteoporosis, 20 with osteopenia, and 9 with normal BMD. During 433.1 person-years (PYs) of observation, 17 fractures occurred in 12 patients (IR, 3.93 [95% confidence interval (CI), 2.46–6.26]/100 PYs); 8.32 (95% CI, 4.09–16.90)/100 PYs in the osteopenia group, 3.40 (95% CI, 1.30–8.90)/100 PYs in the osteoporosis group, and 3.37 (95% CI, 1.53–7.39)/100 PYs in the no BMD test group. Risk factors for fractures were female sex, advanced age (≥ 65 years), longer follow-up duration, initial glucocorticoid dose ≥ 10 mg/day, and higher cumulative glucocorticoid dose over the first 6 months. @*Conclusion@#The incidence rate of fractures in Korean patients with PMR was 3.93/100 PYs. Female sex, advanced age, longer follow-up duration, and increased glucocorticoid dose are risk factors for osteoporotic fracture.

ABSTRACT

Background@#s/Aims: This study was performed to reveal the usefulness of the trabecular bone score (TBS) in assessing bone strength in patients with ankylosing spondylitis (AS) in comparison with dual-energy X-ray absorptiometry (DXA) methods. @*Methods@#A total of 215 AS patients (75.8% male) were enrolled from a single university hospital in Korea. Demographic and clinical information were assessed. Patients completed X-rays of the cervical and lumbar spine (L-spine), and spinal ankyloses were quantified using the modified Stoke AS Spine Score (mSASSS). Hip, anteroposterior and lateral L-spine bone mineral density (BMD) and TBS were assessed by DXA methods. Clinical characteristics and bone strength measurement results were compared between male and female AS patients. The accuracy of each bone strength evaluation method in predicting Fracture Risk Assessment Tool (FRAX) scores indicating moderate or higher fracture risk was compared by receiver operating characteristic curves in patients aged ≥ 40 years. Correlations between each bone strength measurement method and mSASSS were examined. @*Results@#Male patients showed higher mSASSS and less prevalent peripheral joint involvement compared to female patients (p < 0.05). TBS, hip BMD, and L-spine lateral BMD showed comparably high areas under the curve (AUCs) for predicting FRAX-major osteoporotic fractures (MOF) ≥ 10% (AUC ranged 0.72 to 0.76). TBS negatively correlated with mSASSS in both male and female patients (p < 0.01). @*Conclusions@#TBS could predict the risk of MOF and is not influenced by spinal osteoproliferation in AS patients, even in those with advanced spinal changes.
