The Prevalence and Clinical Correlates of an Auscultatory Gap in Systemic Sclerosis Patients
Introduction. Accurate blood pressure (BP) measurement is essential to the diagnosis and management of hypertension in patients with systemic sclerosis (SSc) to help prevent renal and cardiovascular complications. The presence of an auscultatory gap during manual BP measurement—the temporary disappearance of the Korotkoff sounds during cuff deflation—leads to a potentially important underestimate of systolic BP if undetected. Objectives. Since the presence of an auscultatory gap is frequently associated with increased vascular stiffness, we investigated its presence and correlates in 50 consecutive SSc patients. Methods. For each patient, BP was measured sequentially using three different approaches performed in the same order. Results. Sixteen of 50 patients (32%) had an auscultatory gap which if undetected would have resulted in clinically important underestimates of systolic BP in 4 patients. The presence of an auscultatory gap was statistically associated with the presence of antibodies to RNA polymerase III (P<0.0068) and SSc diagnosis type (P<0.01). Conclusions. Our study demonstrates that auscultatory gaps are relatively common in SSc and correlate with markers for SSc vasculopathy. If undetected auscultatory gaps may result in clinically important underestimation of BP. Thus, electronic oscillometric BP may be preferred in SSc patients
Low-Dose Naltrexone for Pruritus in Systemic Sclerosis
Pruritus is a common symptom in systemic sclerosis (SSc), an autoimmune disease which causes fibrosis and vasculopathy in skin, lung, and gastrointestinal tract (GIT). Unfortunately, pruritus has limited treatment options in this disease. Pilot trials of low-dose naltrexone hydrochloride (LDN) for pruritus, pain, and quality of life (QOL) in other GIT diseases have been successful. In this case series we report three patients that had significant improvement in pruritus and total GIT symptoms as measured by the 10-point faces scale and the University of California Los Angeles Scleroderma Clinical Trials Consortium Gastrointestinal Tract 2.0 (UCLA SCTC GIT 2.0) questionnaire. This small case series suggests LDN may be an effective, highly tolerable, and inexpensive treatment for pruritus and GIT symptoms in SSc
Functional articular cartilage repair: here, near, or is the best approach not yet clear?
In this Review we describe three approaches for cartilage tissue repair at the rheumatology–orthopaedics interface: disease-modifying osteoarthritis (OA) drug (DMOAD) treatment; cell-based therapies, and intrinsic cartilage repair by joint distraction. DMOADs can slow the progression of joint damage. Cell-based therapies have evolved to do the same, through selection of the most potent cell types (and combinations thereof), as well as identification of permissive boundary conditions for indications. Joint distraction techniques, meanwhile, have now demonstrated the capacity to stimulate actual intrinsic tissue repair. Although this progress is promising, true biological joint reconstruction remains distant on the developmental pathway of 'regenerative medicine'. Prolonged functional repair—that is, cure of diseases such as OA—remains an unmet medical need and scientific challenge, for which comparative and constructive interaction between these physical, chemical and cellular approaches will be required. Careful selections of patients and combinations of approaches will need to be made and tested to demonstrate their cost-effectiveness. Only with such rational and integrated assessment of outcomes will the promising results of these approaches be consolidated in clinical practice
