Twenty-two points to consider for clinical trials in systemic sclerosis, based on EULAR standards.

OBJECTIVE: SSc is clinically and aetiopathogenically heterogeneous. Consensus standards for more uniform trial design and selection of outcome measures are needed. The objective of this study was to develop evidence-based points to consider (PTCs) for future clinical trials in SSc. METHODS: Thirteen international SSc experts experienced in SSc clinical trial design were invited to participate. One researcher with experience in systematic literature review and three trainees were also included. A systematic review using PubMed and the Cochrane Central Register of Controlled Trials was conducted and PTCs when designing clinical trials in SSc were developed. As part of that development we conducted an Internet-based Delphi exercise regarding the main points to be made in the consensus statement. Consensus was defined as achieving a median score of ≥7 of 9. RESULTS: By consensus, the experts decided to develop PTCs for each individual organ system. The current document provides a unifying outline on PTCs regarding general trial design, inclusion/exclusion criteria and analysis. Consensus was achieved regarding all the main points of the PTCs. CONCLUSION: Using European League Against Rheumatism suggestions for PTCs, a general outline for PTCs for controlled clinical trials in SSc was developed. Specific outlines for individual organ systems are to be published separately. This general outline should lead to more uniform and higher-quality trials and clearly delineate areas where further research is needed.

Associations between a scleroderma-specific gastrointestinal instrument and objective tests of upper gastrointestinal involvements in systemic sclerosis.

OBJECTIVES: UCLA-SCTC-GIT 2.0 is an instrument designed to evaluate gastrointestinal (GI) symptoms in systemic sclerosis (SSc). The objective of our study was to assess the associations between the upper GI (UGI) symptom scales (reflux and distention/bloating [D/B] scales) versus objective/laboratory studies. METHODS: Fifty-five patients with SSc were enrolled at 2 centres. Each patient completed the GIT 2.0 and had objective and laboratory tests. Correlations were assessed using the Spearman's test. We also assessed the average scores in patients with positive vs. negative tests and compared them using the t-test and Wilcoxon test. RESULTS: The mean (SD) age was 53.6 (11.8), 90% were women and 49% had limited SSc. The mean reflux and D/B scores were 0.82 and 1.25, respectively (moderate severity). The reflux scale had moderate correlations with upper GI objective evaluations (correlation coefficient ≥0.40) and was able to differentiate between patients with endoscopy proven esophagitis and manometric abnormalities (p=0.01 for both). D/B scores were numerically higher in patients with abnormal objective tests. The GIT 2.0 reflux and D/B scales had a high sensitivity ranging from 80% to 94% but very low specificity (range; 0-20%) based on objective gold standard GI measures. CONCLUSIONS: The GIT 2.0 reflux and D/B scales have a high sensitivity (range 80-94%) for UGI involvement. The GIT 2.0 instrument complements the objective tests for assessment of the UGI.

Atherosclerosis in systemic sclerosis: a systematic review and meta-analysis.

OBJECTIVE: Systemic sclerosis (SSc) is characterized by calcification, vasculopathy, and endothelial wall damage, all of which can increase the risk of developing atherosclerosis and cardiovascular disease. The aim of this study was to perform a systematic review and meta-analysis to determine whether the risk of atherosclerosis is increased in SSc patients compared to healthy individuals. METHODS: A systematic search was performed to identify studies published in PubMed and the Cochrane database up to May 2010, and recently published abstracts were also reviewed. Two reviewers independently screened articles to identify studies comparing the rate of atherosclerosis in SSc patients to that in healthy controls. The studies utilized one of the following methods: angiography, Doppler ultrasound to assess plaque and carotid intima-media thickness (IMT), computed tomography, magnetic resonance imaging, flow-mediated vasodilation (assessed as the FMD%), the ankle-brachial index, or autopsy. For carotid IMT and FMD% values, we computed a pooled estimate of the summary mean difference and explored predictors of carotid IMT using random-effects meta-regression. RESULTS: Of the 3,156 articles initially identified, 31 were selected for systematic review. The meta-analysis included 14 studies assessing carotid IMT and 7 assessing brachial artery FMD%. Compared to healthy controls, SSc patients had a higher prevalence of coronary atherosclerosis, peripheral vascular disease, and cerebrovascular calcification. Meta-analysis showed that SSc patients had increased carotid IMT (summary mean difference 0.11 mm, 95% confidence interval [95% CI] 0.05 mm, 0.17 mm; P = 0.0006) and lower FMD% (summary mean difference -3.07%, 95% CI -5.44%, -0.69%; P = 0.01) compared to controls. There was marked heterogeneity between the studies, which was mainly attributable to variations in disease duration and differences in the mean/median age between SSc patients and controls. CONCLUSION: Patients with SSc have an increased risk of atherosclerosis compared to healthy subjects. Further studies should elucidate the mechanism of this increased risk.

Association of gastrointestinal involvement and depressive symptoms in patients with systemic sclerosis.

OBJECTIVES: SSc-associated gastrointestinal tract involvement (SSc-GIT) is an important predictor of depressive symptoms. University of California at Los Angeles Scleroderma Clinical trial Consortium Gastrointestinal Tract 2.0 (UCLA SCTC GIT 2.0) is a 34-item valid instrument that captures GIT symptom severity and impact on quality of life. It has seven GI-specific scales and a total GIT score. The objectives were to assess: (i) whether there is an association between depressed mood with GI symptom scales as assessed by the UCLA SCTC GIT 2.0 instrument; and (ii) to explore which GI-specific symptom scales are associated with depressed mood in patients with SSc. METHODS: One hundred and fifty-two patients with SSc completed the UCLA SCTC GIT 2.0 and the Center for Epidemiologic Studies Short Depression scale (CES-D10). Patients were divided into depressed (CES-D ≥ 10) or non-depressed group (CES-D < 10) and compared using t-test or chi-square test. Multiple linear regression was used to determine associations between GI scales and depressed mood (CES-D). RESULTS: Study participants were 84% female, 78% Caucasian and 40% had depressed mood (CES-D10 ≥ 10). Patients with depressed mood had statistically worse GI scale scores (except fecal soilage) and worse total GIT score (P < 0.05). In the multivariable model reflux and constipation scales were independently associated with worse CES-D scores (P = 0.01-0.06) CONCLUSION: SSc-GIT involvement is associated with depressed mood. Reflux and constipation scales of UCLA-SCTC GIT 2.0 were independently associated with CES-D. Future studies should assess if treatment of GIT symptoms will improve depressed mood in patients with SSc-GIT.

Identifying Risk Factors Associated with Inappropriate Use of Acid Suppressive Therapy at a Community Hospital.

Purpose. By examining the prescribing patterns and inappropriate use of acid suppressive therapy (AST) during hospitalization and at discharge we sought to identify the risk factors associated with such practices. Methods. In this retrospective observational study, inpatient records were reviewed from January 2011 to December 2013. Treatment with AST was considered appropriate if the patient had a known specific indication or met criteria for stress ulcer prophylaxis. Results. In 2011, out of 58 patients who were on AST on admission, 32 were newly started on it and 23 (72%) were inappropriate cases. In 2012, out of 97 patients on AST, 61 were newly started on it and 51 (84%) were inappropriate cases. In 2013, 99 patients were on AST, of which 48 were newly started on it and 36 (75%) were inappropriate cases. 19% of the patients inappropriately started on AST were discharged on it in three years. Younger age, female sex, and 1 or more handoffs between services were significantly associated with increased risk of inappropriate AST. Conclusion. Our findings reflect inappropriate prescription of AST which leads to increase in costs of care and unnecessarily puts the patient at risk for potential adverse events. The results of this study emphasize the importance of examining the patient's need for AST at each level of care especially when the identified risk factors are present.

Wire in the heart: fracture and fragment embolization of retrievable inferior vena cava filter into the right ventricle.

We report a case of a 58-year-old female who was found to have a fractured limb of her IVC filter in her right ventricle during a cardiac catheterization. A 25 mm radioopaque thin linear structure was seen in the proximal portion of the right ventricle. It was fixed and did not migrate or change position during investigations. On fluoroscopy, the IVC filter was observed in an appropriate location in the midabdomen. Yet, fractures of at least two of the metal filamentous legs of the IVC device were noticed. The patient was made aware of the many risks associated with filter removal. Due to the high risks of the procedure, she refused surgery and the filter fragment was not removed. We present this case to underscore the potential complications of IVC filters.

Idiopathic bilateral adrenal hemorrhage in a 63-year-old male: a case report and review of the literature.

Adrenal hemorrhage is a largely uncommon condition typically caused by a number of factors including infection, MI, CHF, anticoagulants, trauma, surgery, and antiphospholipid syndrome. Yet, idiopathic bilateral hemorrhage is rare. The authors present a case of a 63-year-old male who presented with abdominal pain that was eventually diagnosed as bilateral adrenal hemorrhages due to an unknown origin. Abdominal CT revealed normal adrenal glands without enlargement, but an MRI displayed enlargement due to hemorrhage in both adrenals. There was no known cause; the patient had not suffered from an acute infection and was not on anticoagulants, and the patient's history did not reveal any of the other known causative factors. The case underscores the importance of keeping bilateral adrenal hemorrhages on the list of differentials even when a cause is not immediately clear. It also raises the question of whether CT is the most sensitive test in the diagnosis of adrenal hemorrhage and whether the diagnostic approach should place greater weight on MRI. The case highlights the need for prompt therapy with steroids once bilateral hemorrhage is suspected to avert the development or progression of adrenal insufficiency.

An unusual presentation of classic idiopathic polyarteritis nodosa as acute interstitial nephritis.

In the medical literature, there have been few reported cases of classic Polyarteritis Nodosa (cPAN) presenting with acute renal failure (ARF) and, unlike microscopic polyangiitis (MPA), no documentation to our knowledge of cPAN with clinical presentation similar to acute interstitial nephritis. We describe a case of ARF and a clinical picture suggestive of acute interstitial nephritis (AIN). However, renal biopsy of this patient showed acute necrotizing intrarenal vasculitis, suggestive of cPAN. Although no guidelines exist for the most appropriate therapy for patients presenting in this fashion, combination therapy with cyclophosphamide and steroids, in our patient, resulted in clinical improvement and resolution of dialysis-dependent renal failure. These findings suggest the potential for good prognosis in patients with cPAN who present with a presumed diagnosis of AIN and dialysis-dependent ARF.
