Bilateral orbital pseudotumor in a patient with Takayasu arteritis: a case report and review of the literature

Inflammatory orbital pseudotumor is often associated with rheumatologic disorders. It has been reported commonly with ANCA-associated vasculitides, especially granulomatosis with polyangiitis (Wegener’s granulomatosis). There are also a few cases of large vessel vasculitis such as giant cell arteritis and Behcet’s disease. Here, we report a patient with undiagnosed Takayasu arteritis presenting with proptosis and diplopia, with later diagnosis of an inflammatory pseudotumor of the orbit. In this case, we believe extensive involvement of blood vessels, including bilateral pulmonary artery stenosis, and elevated inflammatory markers that show disease activity may be related to pseudotumor formation in Takayasu arteritis. Since this is an unusual and unreported presentation of the disease, better estimation of a causal relationship may be possible in the future with further information. In conclusion, although uncommon, this case highlights that orbital pseudotumor may be an important finding in Takayasu arteritis. For early diagnosis, better treatment, and good prognosis, it should be considered in patients presenting with ocular symptoms similar to the other vasculitides.     

The effect of the aspiration of pericardial effusion on intraocular pressure

OBJECTIVE: To assess the effect of pericardial effusion on intraocular pressure (IOP). PATIENTS AND METHODS: Twenty-two patients with pericardial effusion were enrolled into the study. The average pericardial effusion was 2245 +/- 257 cc, and the mean IOP was 26.1 +/- 2.1 mm Hg in the initial examination. Pericardial effusion was aspirated via canula under topical anaesthesia at two or three-day intervals. IOP was measured after every aspiration of pericardial fluid. We statistically compared the changes in the mean IOP after every aspiration (one-way ANOVA), and calculated the correlation (regression analysis) between the amount of fluid and the changes in IOP. RESULTS: An average of 400 ml of fluid was aspirated at two or three-day intervals. The mean IOP decreased to 23.3, 21.2, 19.1 and 16.3 mm Hg after aspirations, respectively. These decreases in the mean IOP were statistically significant (p < 0.01). In regression analysis, we observed a meaningful relationship between the changes in IOP and the amount of pericardial effusion (p < 0.001). CONCLUSION: We found that pericardial effusion affected IOP due to increased episcleral venous pressure. Therefore, patients with pericardial effusion should be referred for an ophthalmological examination with IOP measurement. IOP-lowering medication can eventually be started or adjusted by the ophthalmologist.     

Prospective study of the spontaneous course of subclinical hypothyroidism: prognostic value of thyrotropin,thyroid reserve,and thyroid antibodies

Subclinical hypothyroidism is a frequent syndrome affecting about 10 million people in the United States. The management of such patients is open to debate. In a long-term prospective study we analyzed the spontaneous course and the value of predictive factors in the development of overt thyroid failure. We studied 82 female patients with subclinical hypothyroidism prospectively over a mean observation period of 9.2 yr. TSH, thyroid hormones, thyroid reserve after TRH administration, thyroid antibodies, and clinical parameters were assessed at yearly intervals. The cumulative incidence of overt hypothyroidism was calculated using life-table analysis and Kaplan-Meier curves. According to the initial serum TSH concentrations (TSH, 4-6/>6-12/>12 mU/liter), Kaplan-Meier estimates of the incidence of overt hypothyroidism were 0%, 42.8%, and 76.9%, respectively, after 10 yr (P < 0.0001). When only patients with TSH levels greater than 6 mU/liter were analyzed, the cumulative incidence was 55.3%. The incidence of overt hypothyroidism increased in patients with impaired thyroid reserve (52.6% vs. 38.1%; P = 0.05) and positive microsomal antibodies (58.5% vs. 23.2%; P = 0.03). This prospective long-term study demonstrates that only a part of the cohort of patients with subclinical hypothyroidism develops overt hypothyroidism over time and that a major group remains in the subclinical state after 10 yr. The measurement of TSH, microsomal (thyroperoxidase) antibodies, and thyroid reserve allows initial risk stratification for the development of overt thyroid failure (risk ratio ranging from 1.0-15.6). Our study helps to recognize the spontaneous course of subclinical hypothyroidism and in the identification of patients most likely to progress to overt hypothyroidism.     

High frequency of inflammatory back pain and other features of spondyloarthritis in patients with rheumatoid arthritis

The aim of this study was to investigate the frequency of patients with rheumatoid arthritis (RA) who have inflammatory back pain (IBP) and meet the existing classification criteria for ankylosing spondylitis (AS) and spondyloarthritis (SpA). We included 167 patients fulfilling the ACR 1987 revised criteria for RA. After obtaining a medical history and performing a physical examination, standard pelvic X-rays for examination of the sacroiliac joints (SIJ) were ordered in all patients. A computed tomography (CT) or magnetic resonance imaging (MRI) of SIJ was performed in patients with suspected radiographic sacroiliitis and MRI of SIJ in those who have IBP but no radiographic sacroiliitis. IBP was defined according to both Calin and experts’ criteria. The modified New York (mNY) criteria were used to classify AS, both ESSG and Amor criteria for SpA and ASAS classification criteria for axial SpA. There were 135 female and 32 male patients with a mean age of 54.8 years. The mean disease duration was 9.8 years. RF was positive in 128 patients (79.2 %) and anti-CCP in 120 patients (81.1 %). Twenty-eight patients with RA (16.8 %) had IBP (Calin criteria), and four (2.4 %) had radiographic sacroiliitis of bilateral grade 3. Three patients (1.8 %) fulfilled the mNY criteria for AS, 31 (18.6 %) ESSG and 26 (15.6 %) Amor criteria for SpA. Nine patients (five with MRI sacroiliitis) (5.3 %) were classified as having axial SpA according to new ASAS classification criteria. This study suggests that the prevalence of SpA features in patients with RA may be much higher than expected.     

Hyperuricemia and its related factors in an urban population, Izmir, Turkey

The aim of this study was to examine the prevalence of hyperuricemia and its associated factors in an urban area of Izmir, located in western Turkey. Our study group was selected by computerized sampling from the participants of a larger population-based study searching for the prevalence of rheumatoid arthritis in Balcova and Narlidere districts of Izmir. A total of 132 subjects (69 women and 63 men) were included in this study. Serum uric acid, glucose, creatinine and lipid levels were studied. Body composition along with body fat percentage was determined anthropometrically. A total of 16 subjects had hyperuricemia (4 women and 12 men). The overall prevalence of hyperuricemia was 12.1% and the mean uric acid level was 4.9 ± 1.3 mg/dl. Males had significantly higher uric acid levels than females (P < 0.05; 5.5 ± 1.3 vs. 4.3 ± 1.1 mg/dl, respectively). The prevalence of hypertension, diabetes, obesity and metabolic syndrome was 24.4, 5.3, 28 and 26.5%, respectively. There was no gouty subject. Sum of skinfold thickness (SFT) measurements and creatinine levels were the independent predictors of hyperuricemia (β = 0.45, 0.47, respectively). Uric acid measurement is important not only for inflammatory rheumatic disorders but also for predicting metabolic syndrome and related coronary artery disease. There is sex difference in uric acid levels in favor of women most probably explained by gonadal hormones. Hyperuricemia is significantly predicted by anthropometric measure of SFT which is a simple clinical screening method along with creatinine levels.     

Osteoprotegrin interacts with biomarkers and cytokines that have roles in osteoporosis,skin fibrosis,and vasculopathy in systemic sclerosis: A potential multifaceted relationship between OPG/RANKL/TRAIL and Wnt inhibitors

Abstract

Objectives: We explored the interactions of osteoprotegerin (OPG) with biomarkers of bone turnover and cytokines, including soluble receptor activator for nuclear factor kappa beta ligand (sRANKL), tumor necrosis factor-related apoptosis-induced ligand (TRAIL), and Wnt inhibitors in osteoporosis, vasculopathy and fibrosis related to systemic sclerosis (SSc).

Methods: The study included 46 SSc patients and 30 healthy controls. Skin thickness, pulmonary fibrosis and/or hypertension, digital ulcers, and calcinosis cutis of SSc patients were assessed. We determined bone mineral density (BMD), and OPG, sRANKL, TRAIL, secreted frizzled-related protein 1 (sFRP-1), Dickkopf-related protein 1 (DKK-1), sclerostin in the serum of both patients and controls.

Results: OPG, sclerostin, and sFRP-1 levels were similar between patients and controls (P?>?0.05). Femoral neck and lumbar spine BMD and vitamin D levels were lower, and the OC, NTX, sRANKL, DKK1 and TRAIL levels were significantly higher, in patients than in controls (p?<?0.05). In subgroup analysis, patients with higher modified Rodnan skin score (mRodnan) had higher DKK-1, sclerostin, and TRAIL levels (p?<?0.05); those with diffuse SSc subtype had lower BMD values than those with limited SSc (p?<?0.05). Skin and pulmonary fibrosis linked negatively with BMD measures.

Conclusion: we showed that sRANKL levels were higher and correlated with bone turnover markers. It may be related to osteoporosis in SSc. The OPG level was unaltered in SSc patients. Higher TRAIL levels associated with skin thickness may indicate vascular dysfunction or injury. Higher DKK-1 and sclerostin levels may be related to a reactive increase in cells and be prominently linked to fibrosis in SSc.     

The role of body mass index and other body composition parameters in early post-transplant complications in patients undergoing allogeneic stem cell transplantation with busulfan–cyclophosphamide conditioning

Patients with impaired nutritional status may show increased risk of hematopoietic stem cell transplantation (HSCT)-related complications. This study was conducted to determine whether body mass index (BMI) and other body composition parameters, such as lean body mass index (LBMI) and body fat mass (BFM), are associated with early post-transplantation toxicity and mortality in allogeneic HSCT recipients. The records of 71 patients diagnosed with acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), chronic myeloid leukemia (CML), or myelodysplastic leukemia (MDS) who had undergone allogeneic HSCT with a conditioning regimen of busulfan–cyclophosphamide (Bu–Cy), between September 2003 and January 2009 at the Stem Cell Transplantation Unit of Gazi University Hospital were retrospectively evaluated. BMI was found to be negatively correlated with the NCI grade of mucositis, cardiotoxicity, emesis, and hyperglycemia, and with the number of erythrocyte transfusions. LBMI was also negatively correlated with the number of erythrocyte transfusions, cardiotoxicity, emesis, and hyperglycemia. BFM was negatively correlated with the day of neutrophil engraftment, and NCI grade of mucositis. Nutritional status did not have an impact on overall survival (OS), progression-free survival (PFS), or 100-day transplant related mortality (TRM).
