Evaluation of balance in patients with systemic sclerosis.

BACKGROUND: The aim was to examine static/dynamic balance and proprioception of Systemic Sclerosis by comparing healthy and relationship with demographic and disease-related data. METHODS: 21 Systemic Sclerosis and 19 healthy were included.Berg Balance Scale (functional balance), Sensamove Sensbalance Maxiboard Software (static, dynamic balance:reaction time and travel time and proprioception), Scleroderma Health Assessment Questionnaire/Health Assessment Questionnaire (health status), Medsger's Disease Severity Scale, Modified Rodnan Skin Score were used in evaluation. FINDINGS: Comparing the groups, there was significant difference in Berg Balance Scale (p:0.036); Health Assessment Questionnaire/Scleroderma Health Assessment Questionnaire (p:0.001); Static balance-center (p:0.001), front (p:0.001), back (p:0.001), left (p:0.001), right (p:0.021); proprioception-front (p:0.025);Reaction Time-front (p:0.031) and left (p:0.010);Travel Time-front (p:0.041) and left (p:0.014) in favor of healthy group.In Systemic Sclerosis, disease severity had moderate correlation with static balance-back (r:-0.504,p:0.020).Skin thickness had low correlation with Reaction Time-front (r:-0.449,p:0.041).Age had low correlation with Travel time-front (r:0.458,p:0.037) and proprioception-left (r:0.450,p:0.041); moderate with Travel time-back (r:0.515;p:0.017) and proprioception-front (r:0.539,p:0.012). INTERPRETATION: Compared to healthy, Systemic Sclerosis had worse health status, functional balance, static/dynamic balance and proprioception.This situation is related to disease severity, skin thickness and age. Evaluations made with objective methods may have the potential to determine the extent of the problem.Clinicians can guide the treatment of patients with SSc by evaluating their static/dynamic balance and proprioception.With early treatment, additional problems that may occur due to worsening of balance and proprioception can be prevented.Proprioception and dynamic balance evaluation can be performed for older patients, static balance when disease activity is high, and dynamic balance when skin thickness score is high.

Peripheral Arthritis and Tenosynovitis in a Patient With Brucellosis.

Brucellosis is an infectious disease caused by Gram-negative bacteria. Musculoskeletal system involvement is common in patients with brucellosis. Herein we report a patient who presented with bilateral arthralgia in the ankles and diffuse swelling of the left hand in the follow-up. He had been diagnosed with brucellosis and improved well after a 10-week duration of antibiotic therapy. Rheumatic diseases may have many infectious mimickers. Brucellosis is one of those that should be considered in the differential diagnosis.

Investigation of Biopsychosocial Status, Fatigue, Sleep Quality, Alexithymia, Cognitive Functions, and Quality of Life in Behçet's Disease.

Objective: The aim of this study was to compare the effects of Behçet's disease in terms of anxiety, biopsychosocial status, fatigue, sleep quality, alexithymia, cognitive level, and quality of life according to major and minor organ involvement. Methods: The study was planned as a single-centre cohort study. Fifty patients diagnosed with Behçet's (mean age 43±11.96 years) were included in the study. The patients were divided into two groups as major organ involvement (uveitis, neuro-Behçet's, or vascular type Behçet's disease) and minor organ involvement (mucocutaneous type Behçet's disease). Biopsychosocial status was evaluated with Biopsychosocial Questionnaire (BETY-BQ), anxiety with Beck Anxiety Inventory (BAI), fatigue with Multidimensional Assessment of Fatigue (MAF) Scale, sleep quality with Pittsburgh Sleep Quality Index (PSQI), alexithymia with Toronto Alexithymia Scale-20 (TAS-20), cognition level with Mini-Mental State Examination (MMSE), and quality of life with Short Form-36 (SF-36). Results: In the comparison according to minor and major organ involvement, there was no significant difference between the groups in BETY-BQ, BAI, MAF, PSQI, TAS-20, MMSE and SF-36 (p>0.05). Conclusion: Behçet's disease negatively effects in parameters such as biopsychosocial status, fatigue, sleep quality, alexithymia and quality of life. The presence of major or minor organ involvement in the patients did not change these negative effects.

The validity and reliability of the Turkish version of the Brief Fear of Negative Evaluation Scale - straight forwardly in patients with systemic sclerosis.

Objective: This study aimed to examine the validity and reliability of Turkish version of Brief Fear of Negative Evaluation Scale-Straightforwardly (BFNE-S (TR)) in patients with Systemic Sclerosis (SSc). Materials and Methods: 35 individuals (mean age: 53.3±13.0 years) diagnosed as SSc were included. Data on demographics, were collected via structured interview. All participants were evaluated by same investigator. The disability was evaluated with Scleroderma Health Assessment Questionnaire (SHAQ), disease severity with Medsger's Disease Severity Scale, and skin involvement with Modified Rodnan Skin Score. BFNE-S (TR) was applied to the patients with SSc who did not receive any treatment for test retest at one-week intervals. Results: The one-factor structure was provided for all indices except Chi-Square. Factor loadings were significant. The patient responses to the BFNE-S (TR) demonstrated excellent internal consistency (Cronbach's α: 0.95). The floor effect (20%) percentage of patients who scored at floor level, was observed. Test-retest reliability of the scale was excellent with 0.91 (95%CI: 0.78-0.96). BFNE-S (TR) total score had positive correlation with SHAQ_Digestive (r=0.503) and SHAQ_Raynaud phenomenon (r=0.343)(p<0.05). Conclusions: The BFNE-S (TR) is a reliable and valid scale and can be used for measurement of fear of negative evaluation in SSc.

Intestinal Peripheral T-Cell Lymphoma in a Patient with Ankylosing Spondylitis Under Treatment with Infliximab: A Case Report and Review of the Literature.

Background: Recent literature involves many cases with lymphoma and ankylosing spondylitis (AS) with or without the use of TNF inhibitors. Herein, we report a patient, a 56-year-old Human Leukocyte Antigen-B27 (HLA-B27) positive man with four years history of AS who was still under treatment with infliximab with clinical remission. He was admitted with a new-onset, 6-week history of bloody diarrhoea with mucus, abdominal pain, fever, and weight loss. An ileocolonoscopy showed linear ileocecal valve ulcers. Histopathological findings of ileocecal valve ulcers revealed peripheral T-cell lymphoma of the small intestine. Infliximab was interrupted because of the possible progression of the lymphoma. Methods: We aimed to emphasize the underlying potential pathogenic mechanisms and to review the related literature. A literature search was conducted in the PubMed database between January 1980 and November 2020. The keywords including 'ankylosing spondylitis' and 'lymphoma' were used. Conclusion: TNFi use, immunosuppression, and chronic inflammation may be related to the development of lymphoma in chronic inflammatory diseases. Ileocecal valve involvement should not be interpreted as inflammatory bowel disease, infection, or vasculitis in the presence of red flags.

Evaluation of the controlling nutritional status score and prognostic nutritional index in patients with familial Mediterranean fever.

OBJECTIVE: Familial Mediterranean fever (FMF) is the most common disease that leads to secondary amyloidosis in Turkish population. The prognostic nutritional index (PNI) and the controlling nutritional status (CONUT) score were recently investigated in many clinical conditions as predictors of disease activity and prognosis of underlying disease. We aimed to evaluate these indexes in FMF patients. METHODS: We included a total of 135 patients with FMF without amyloidosis at baseline. Demographic characteristics, particular attack features, treatment modalities, disease complications of patients, and a follow-up time for each patient were obtained. Disease complications were defined as amyloidosis or end stage renal disease. Baseline laboratory parameters in the attack-free period were used to assess the subclinical inflammation. Spearman's rho correlation analysis was used for numerical variables. Univariate and multivariate logistic regression analyses were used to determine factors that had an impact on the development of amyloidosis. Receiver operating characteristic (ROC) curve analysis was used to discover the appropriate cutoff points of CONUT score and PNI for predicting the development of amyloidosis. RESULTS: ROC analysis revealed that the optimal cutoff points for neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), CONUT score, and PNI were >1.9, >145, >2, and ≤54, respectively. The area under the curve values of CONUT score and PNI for predicting the development of amyloidosis were 0.830 (95% CI: 0.76-0.89, P < .001) and 0.940 (95% CI: 0.88-0.97, P < .001), respectively. Correlation analyses revealed significant positive correlations between CONUT score, NLR, and PLR. The high CONUT score was associated with the development of amyloidosis in FMF patients in addition to age and M694V homozygous mutation. CONCLUSION: Low PNI and high CONUT score at diagnosis may have a poor prognostic value for the development of amyloidosis in patients with FMF in addition to older age and M694V homozygous mutation. These indexes may be a useful and inexpensive screening biomarkers in clinical practice for predicting amyloidosis in patients with FMF.

Efficacy of local oxygen-ozone therapy for the treatment of digital ulcer refractory to medical therapy in systemic sclerosis: A randomized controlled study.

BACKGROUND: This study aimed to investigate the efficacy of local oxygen-ozone therapy in systemic sclerosis (SSc) patients with digital ulcers (DUs) who were resistant to medical therapy and had impairment in activities of daily living. METHODS: Participants' demographic data, and clinical parameters were recorded. Twenty-five SSc patients with DUs were randomized to the ozone group (I) (n = 13) to receive medical treatment plus local oxygen-ozone therapy and the control group (II) (n = 12) to receive medical treatment only. Hand functions were assessed using the Health Assessment Questionnaire (HAQ) and the Modified Hand Mobility in Scleroderma (HAMISm) test. Clinical parameters, HAQ, and mHAMIS scores were re-evaluated in participants 4 weeks after the initiation of treatment. RESULTS: Demographic and clinical characteristics of the two groups showed no significant differences. At 4 weeks after the initial treatment, the efficacy rate was significantly higher in the ozone group than that in the control group (92% versus 42% P = 0.010). Clinical parameters, HAQ, and HAMISm scores were significantly improved in the treatment group compared to those in the control group (P < 0.05). CONCLUSION: Local oxygen-ozone therapy was effective in the treatment of SSc patients with resistant DUs and improved clinical parameters and functional disability.

Successful Treatment of Systemic Lupus Erythematosus-Associated Thrombocytopenia with Eltrombopag: A Report of Two Cases and Literature Review.

Thrombocytopenia is one of the common haematological manifestations, occurring in 7% to 30% of systemic lupus erythematosus (SLE) patients. Immune thrombocytopenia (ITP) may occur in variable pathways as a result of cross-reacting antibodies or immune complexes that bind to platelet receptors, or infection of progenitor megakaryocytes, and decreased production of thrombopoietin (TPO). It was shown that the vast majority of SLE patients with thrombocytopenia had increased levels of anti-glycoprotein IIb/IIIa (anti-GPIIb/IIIa) or anti-thrombopoietin receptor (anti-TPOR). Eltrombopag is a thrombopoietin receptor agonist that binds to the transmembrane portion of the surface receptor and induces maturation of megakaryocytes and production of platelets. Herein, we report two SLE patients with severe thrombocytopenia who are also refractory to both intravenous immunoglobulin (IVIG), rituximab, and splenectomy. Ultimately, they successfully treated with eltrombopag without any complication. Eltrombopag worked well and their platelet counts increased above 200,000/mm3 only two weeks later.

IL-23R gene polymorphisms in rheumatoid arthritis.

Rheumatoid arthritis (RA) is a common autoimmune disease in which many different genetic variants of functional gene polymorphisms may play a culprit role in the underlying pathogenetic mechanism. The recent studies suggest that interleukin-23 receptor (IL-23R) gene polymorphisms may increase susceptibility to the development of various autoimmune diseases. We aimed to examine the possible relationship of nine single nucleotide polymorphisms (SNPs) in the IL-23R gene to susceptibility to rheumatoid arthritis and their associations with disease characteristics in the South Aegean region of Turkey. We enrolled 100 rheumatoid arthritis patients and age- and sex-matched 96 healthy subjects in the study. After deoxyribonucleic acid (DNA) isolation was performed, a 'Restriction Fragment Length Polymorphism' (RFLP) method was used for the investigation of polymorphisms associated with the IL-23R gene. Allele identification and genotyping were obtained from polymerase chain reaction (PCR) products using gel electrophoresis. Allele frequencies and detected genotypes were compared between groups. All statistical analyses were performed using SPSS 25.0 (IBM SPSS Statistics 25 software (Armonk, NY: IBM Corp.)). Continuous variables were defined by the mean ± standard deviation and categorical variables were defined by number and percent. Logistic Regression Analysis was used for determining which variables affect the presence of RA. Differences between categorical variables were analyzed with Chi-square analysis. Statistical significance was determined as p < 0.05. The mean age was 53.48 ± 11.7 years in the RA group, whereas 52.55 ± 12.7 years in the healthy control group. The genotypes of IL-23R with rs11805303(TT), rs10889677(AA), rs1004819(AA), and rs7530511(CT) polymorphisms were seen more often in RA patients than healthy controls. Having the AA genotype of IL-23R rs1004819 and the CT genotype of Il-23R rs7530511 increase the development risk of RA with a statistical significance (OR: 3.416 p = 0.003 and OR: 4.899 p = 0.0001, respectively). RA patients with the CC genotype of Il-23R with rs11805303, the CC genotype with rs10889677, and the TT genotype with rs2201841 of the IL-23R gene had higher erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels than with other genotypes. RA patients with the CC genotype rs11805303 and the GG genotype rs1004819 of the IL-23R gene had more active disease. Our findings suggest that all of the nine analyzed IL-23R gene polymorphisms are seen more frequently than healthy controls in our study population. Besides, some SNPs were related to higher acute phase reactants and higher disease activity scores.

Cut-Off Value of Serum Uric Acid for Development of Gout Disease in Patients with Multiple Co-Morbidities.

OBJECTIVE: This study aimed to determine the association between hyperuricemia, comorbid diseases and risk of developing gout disease in a Turkish population in a long follow-up period. METHODS: A total of 2000 Turkish adults were cross-sectionally analysed for serum urate levels in 2009 at the Pamukkale University Faculty of Medicine. All patients on regular follow-up at our tertiary health center (n=1322) were included in this study. Demographic features (age and gender), comorbid clinical conditions, and medication use were noted. The risk of developing gout and the determinant factors were investigated. Multivariate logistic regression analysis was performed to analyse causative effects of factors while receiver operating characteristic (ROC) curve analysis was used to identify optimal cut-off values of uric acid level for predicting the development of gout. RESULTS: Among 1322 patients, the mean age was 56.9 (SD:14.68) years. 57.3% (n=758) of the patients were female. The most common co-morbid disease was chronic kidney disease (581, 43%), followed by hypertension (522, 39.4%). Gout developed in 25 patients (1.8%). Gout development risk and presence of all the above comorbidities were significantly higher in patients with serum urate ≥7mg/dl compared with <7mg/dl. Male gender and not using urate lowering drugs were the main risk factors for developing gout disease. ROC analysis of serum uric acid levels identified a cut-off value of >7 (AUC: 0.776, sensitivity 86.96%, specificity 66.74%). CONCLUSION: There is still a dilemma concerning the culprit effects of both comorbidities and hyperuricemia on the risk of developing gout disease.

Ultrasonographic measurement of the vascular wall thickness and intima-media thickness in patients with Behçet's disease with symptoms or signs of vascular involvement: A cross-sectional study.

OBJECTIVES: This study aims to measure and compare bilateral carotid intima-media thickness (CIMT), bilateral jugular, common femoral, and main portal vein wall thicknesses (VWTs) in Behçet's disease (BD) patients with and without vascular involvement to obtain a cut-off value for vascular complications and determine their relationship with disease activity. PATIENTS AND METHODS: Sixty-three BD patients (41 males, 22 females; median age: 38.0 years; min 20 - max 71 years) and 30 healthy control subjects (14 males, 16 females; median age: 40.3 years; min 21 - max 60 years) were included in this cross-sectional study between February and March 2020. According to imaging findings, BD patients were divided into two groups as those with and without vascular complications. Disease duration, medical treatment and BD manifestations of patients were questioned. Disease activity was evaluated using the Behçet's Disease Current Activity Form (BDCAF) and the Behçet's Syndrome Activity Scale (BSAS). Two radiologists blinded to the diagnosis of BD used ultrasound to measure VWT and CIMT. Receiver operating characteristics were assessed to obtain sensitivity and specificity values for each VWT and CIMT. RESULTS: The groups were similar in terms of age, sex, and body mass index (p>0.05). There was a significant difference between the BD groups when the BDCAF and BSAS scores were compared, while there was no difference between them in terms of disease duration and medical treatment (p>0.05). All VWTs and CIMTs were significantly higher in patients with BD compared to healthy controls (p<0.05). There was no significant difference between the BD groups in terms of CIMT, jugular and common femoral VWTs (p>0.05). But portal VWT was significantly higher in patients with vascular involvement (p<0.05). A cut-off value of ≥1.35 mm yielded a sensitivity of 79.2% and a specificity of 82.4% for the diagnosis of vascular involvement with the highest Youden's index (area under the curve, 0.869; 95% confidence interval, 0.783 to 0.956). CONCLUSION: Portal VWT has high sensitivity and specificity for the screening of vascular involvement in patients with BD.

Role of rehabilitation in a COVID-19 survivor with intensive care unit-acquired weakness: A case report.

Intensive care unit-acquired weakness (ICU-AW) is a catastrophic and debilitating clinical condition that causes generalized weakness and predisposes to adverse short- and long-term outcomes. Novel coronavirus disease-2019 (COVID-19) has been a global pandemic since November 2019. Each additional ICU admission for COVID-19 stresses intensive care unit (ICU) and hospital capacity. Accurately designed, timely rehabilitation procedures may reduce the patient burden of ICUs and hospitals. In this article, we describe a COVID-19 survivor who developed acute respiratory distress syndrome (ARDS) and ICU-AW. Early pulmonary rehabilitation in the ICU and long-term rehabilitation maintenance after the ICU and hospital discharge resulted in a positive outcome.

Development of Two Types of Skin Cancer in a Patient with Systemic Sclerosis: a Case Report and Overview of the Literature.

Systemic sclerosis (SSc) is an uncommon rheumatic disease in which the underlying main histopathologic feature is a thickening of the skin due to excessive accumulation of collagen in the extracellular tissue. Fibrogenesis, chronic inflammation, and ulceration may eventually promote skin neoplasms. Although nonmelanoma skin cancer (NMSC) is the most frequent type, there have been restricted case reports and case series with skin cancers in SSc patients in the literature. Herein, we describe a 78-year-old woman diagnosed with diffuse cutaneous systemic sclerosis thirteen years ago and associated nonspecific interstitial pneumonia that was successfully treated with high cumulative doses of cyclophosphamide. She developed basal cell carcinoma and squamous cell carcinoma of the skin in the follow-up. She is still on rituximab treatment with stable interstitial lung disease as indicated by pulmonary function tests and high-resolution chest computed tomography. To our knowledge and a literature search, this is the first reported patient with SSc with two types of skin cancer. In this review, we also aimed to emphasize the relationship between SSc and skin cancer, and possible risk factors for SSc-related skin cancer.

A single center experience: physician related diagnostic delay and demographic and clinical differences between patients with ankylosing spondylitis and non-radiographic axial spondyloarthritis.

Background. A large number of comparative studies have been conducted for ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-axSpA), including disease burden, treatment modalities and patient characteristics. The aim of this study was to compare physician related diagnostic delay time between patients with AS and nr-axSpA. Methods. In our retrospective study we included 266 patients with axSpA. Patients were classified into two subgroups, AS and nr-axSpA. The time from back pain onset until diagnosis of axSpA was defined as the diagnostic delay. The first specialist referred to and the first diagnosis for each patient was noted in detail. Patient characteristics, clinical manifestations and laboratory and imaging results at diagnosis were also compared between subgroups. Results. The diagnostic delay time was significantly longer for AS patients [6 ± 8.14 years vs 1.62 ± 2.54 years]. 40.9% of all patients were initially consulted by specialists in physical therapy and rehabilitation, followed by 29.7% consulted by a neurosurgeon and 19.9% by a rheumatologist. The most common initial diagnosis was fibromyalgia, 52.6% (140), followed by ankylosing spondylitis, 28.9% (77), and lumbar disc hernia, 12.7% (34). Conclusion. The vast majority of patients were initially evaluated by healthcare providers other than rheumatologists and mostly diagnosed with fibromyalgia. Efforts to increase awareness and to educate first healthcare providers may shorten the diagnostic delay time.

Levels of Carbohydrate Antigen 125 in Patients With Adult Onset Still Disease: A Case Report.

Adult onset Still disease (AoSD) is a rare systemic polygenic non-familial autoinflammatory disease. There is no specific biological parameter for diagnosis of AoSD today. This paper presents a case series of three patients with AoSD who had elevated baseline levels of carbohydrate antigen 125 (CA 125). The clinical course of patients was favorable with treatment modalities including steroids and non-steroidal anti-inflammatory drugs. After a comprehensive literature search, it appears that this is the first paper on the association between AoSD and CA 125.

Rare Association of Antiphospholipid Antibody Syndrome, Systemic Lupus Erythematosus and Aortic Dissection: A Striking Presentation with Multi-Organ Failure?

Systemic lupus erythematosus is a chronic autoimmune disease with a wide variety of clinical presentations induced by different immunocomplexes and autoantibodies. Antiphospholipid antibody syndrome (APLAS) is a life-threatening clinical condition characterized by venous and arterial thromboses or pregnancy morbidity in the presence of persistent moderate/high levels of antiphospholipid antibodies. Aortic dissection is rarely associated with APLAS and always requires prompt diagnosis and early treatment. We report a rare case with a striking presentation. The patient developed multi-organ failure due to lethal aortic dissection and the obstruction of abdominal and thoracic branch vessels. LEARNING POINTS: Aortic dissection is a rare lethal clinical condition that always requires prompt diagnosis and early treatment.Signs of multi-organ ischaemia due to obstruction of abdominal and thoracic branch vessels should be kept in mind by clinicians.Venous thrombosis and medial wall necrosis in the aorta may be underlying complex pathophysiological mechanisms in patients with antiphospholipid antibody syndrome.

A Rare Case with Systemic Lupus Erythematosus Manifested by two Different Neurologic Entities; Guillain Barre Syndrome and Posterior Reversible Encephalopathy Syndrome.

Systemic lupus erythematosus (SLE) is an immune-mediated, lifelong disease characterized by quite heterogeneous neuropsychiatric manifestations. Herewith, we report the first rare co-incidental case with posterior reversible encephalopathy syndrome (PRES), Guillain Barre Syndrome (GBS), and (SLE). The coexistence of these neurological conditions in SLE patients could lead to delayed diagnosis and treatment due to this rare coalescence and clinical diversity. Currently, there are no specific, diagnostic radiological or laboratory biomarkers for neurological involvement in SLE. Awareness and, early recognition of neuropsychiatric involvements of the disease are important for timely appropriate treatment. Delayed treatment may cause permanent damage, poor prognosis, long term morbidity, and even death.

Validation of the Simple Psoriatic Arthritis Screening (SiPAS) questionnaire in a Turkish psoriatic population.

OBJECTIVES: Screening of psoriatic arthritis (PsA) in patients with psoriasis (PsO) is critical for the prevention of irreversible joint erosions, deformity, and disability. The SiPAS questionnaire is a short, simple and useful tool designed to screen PsA. This study aimed to evaluate validity of the SiPAS questionnaire in Turkish patients with PsO. MATERIALS AND METHODS: The Turkish translation of SiPAS was sent to us by the developer authors of the original index. Subjects were recruited from dermatology outpatient clinics. All patients' demographic parameters and SiPAS questionnaire results were recorded. After patients completed the questionnaire they were assessed by a rheumatologist according to standard protocol which included a complete history, detailed physical examination, laboratory tests and Classification for Psoriatic Arthritis (CASPAR) criteria. Receiver operating characteristics (ROC) were assessed to obtain sensitivity and specificity of the Turkish version of the SiPAS questionnaire. RESULTS: One hundred and thirty subjects were recruited into the study. The mean age of subjects were 43.5 years and the 55.4% of subjects were female. Of these, after rheumatologic evaluation 42 patients were diagnosed as PsA. The area under the ROC curve was 0.994 which means as excellent predictor and optimum cut-off threshold to discriminate patients diagnosed with PsA was 3 according to this ROC curve analysis. The overall sensitivity and specificity based on cut-off threshold of 3, were 97.6% and 94.3%, respectively. CONCLUSIONS: The Turkish version of the SiPAS questionnaire is a simple useful, time-saving and valid tool for screening PsA in patients diagnosed with PsO with its high sensitivity and specificity. A SiPAS score ≥3 is an indication for referral to a rheumatologist.

Hypertrophic Osteoarthropathy Presenting as Rheumatoid Arthritis Mimicker: A Case Report.

Paraneoplastic rheumatologic syndromes are defined as clinical conditions that mimic primary rheumatic disease in the course of cancer; they generally improve with the effective treatment of underlying malignancy. Hypertrophic osteoarthropathy (HOA) is one of the paraneoplastic syndromes, and it is characterized by the combined presence of periostosis, digital clubbing, and swelling of soft tissues, skin, and joints in the distal extremities. HOA is commonly associated with intrathoracic malignancies (primary lung tumors or metastases). In this report, we discuss a patient with HOA secondary to lung adenocarcinoma, who was admitted with symmetric polyarthritis presenting as elderly onset rheumatoid arthritis. He was successfully treated with chemotherapy ablation for underlying malignancy. Anti-inflammatory drugs were also administered. HOA should be kept in mind in the differential diagnosis of inflammatory arthritis.
