Left ventricular dysfunction and arrhythmias in asymptomatic patients with systemic sclerosis.

INTRODUCTION AND AIMS: Cardiac involvement in systemic sclerosis (SS) is frequently silent and a major cause of mortality in these patients. This work aims to study the prevalence and associations of left ventricular dysfunction (LVD) and arrhythmias in SS. METHODS AND RESULTS: Prospective study of SS patients (n=36), excluding those with symptoms of (or) cardiac disease, pulmonary arterial hypertension or cardiovascular risk factors (CVRF). A clinical, analytical, electrocardiogram (EKG), Holter, and echocardiogram with global longitudinal strain (GLS) assessment were performed. Arrhythmias were classified into clinically significant arrhythmias (CSA) and non-significant. Twenty-eight percent had left ventricular diastolic dysfunction (LVDD), 22% LV systolic dysfunction (LVSD) according to the GLS, 11.1% both, and 16.7% cardiac dysautonomia. Fifty percent presented alterations by EKG (44% CSA), 55.6% by Holter (75% CSA) and 8.3% CSA by both. An association was found between the elevation of troponin T (TnTc) and CSA and between the elevation of both NT-proBNP and TnTc with LVDD. CONCLUSIONS: We found a higher prevalence of LVSD than in the literature, detected by GLS and being 10 times higher than that detected by LVEF, which justifies the need to incorporate this technique in the routine evaluation of these patients. The association of TnTc and NT-proBNP with LVDD suggests that they can be used as minimally invasive biomarkers of this affectation. The absence of correlation between LVD and CSA indicates that the arrhythmias could be due, not only to a supposed structural alteration of the myocardium, but to an independent and early cardiac involvement, which should be actively investigated even in asymptomatic patients without CVRF.

Comparative efficacy of intra-articular hyaluronic acid and corticoid injections in osteoarthritis of the first carpometacarpal joint: results of a 6-month single-masked randomized study.

OBJECTIVE: The study aim was to compare the efficacy and safety of ultrasound-guided intra-articular injections of hyaluronic acid and betamethasone in the management of patients with osteoarthritis of the thumb. METHODS: Eighty-eight evaluable patients diagnosed with osteoarthritis of the thumb (Kellgren-Lawrence grade II-III) received ultrasound-guided intra-articular treatment with hyaluronic acid (48) or betamethasone (40). In total, 3 local injections were scheduled at 7-day intervals. Assessments were performed at baseline and at 7, 14, 30, 90, and 180 days. RESULTS: In both study groups, the pain Visual Analogue Scale and Functional Index for Hand Osteoarthritis scores decreased significantly during follow-up compared to baseline. There were no significant differences between the groups. However, at 90 days, the functional score showed a trend towards greater clinical improvement in the hyaluronic acid group (P 0.071). A subanalysis of patients with Functional Index score≥5 and Visual Analogue Scale score≥3 at baseline showed a significantly higher median functionality score in the hyaluronic acid group (P 0.005 at 90 days and P 0.020 at 180 days). Further limiting analysis to a baseline pain score≥5 showed significantly greater improvement in functionality score (P 0.004 at 180 days), which was already apparent after the second intra-articular injection at 14 days (P 0.028). In this patient subset, the mean pain score also improved significantly at 180 days (P 0.02). CONCLUSIONS: Both hyaluronic acid and betamethasone were effective and well-tolerated for the management of rhizarthrosis. Hyaluronic acid was more effective over time and more efficiently improved functionality and pain in patients with more severe symptoms.

Safety profile of biological intravenous therapy in a rheumatoid arthritis patients cohort. Clinical nursing monitoring (Sebiol study).

INTRODUCTION: The Biologics used in the management of rheumatoid arthritis (RA) in recent years, have comprehensively permitted to understand its security, as shown in registries such as BIOBADASER. The present manuscript represents an observational cohort study to describe the safety perinfusional profile of those intravenous treatments. OBJECTIVES: To confirm the safety profile of biological therapies in routine clinical practice, after the administration of intravenous drugs and 24 hours post-administration. MATERIAL AND METHODS: We evaluated a cross-sectional cohort of 114 patients with RA (according to the American College of Rheumatology ACR criteria), attending within one month in 2009 the nursing clinics of day care hospital of 12 Catalonian hospitals. All patients were treated with intravenous biological agents. We recorded the age, sex, current and previous drug treatments, we also collected data about previous vaccination and premedication received and any adverse event occurring at the time of drug administration or within 24 hours. If an adverse event occurred, was categorized by MedDRAv11.0 International Dictionary, and categorized in terms of intensity (mild, moderate, severe), relationship to drug administration according to Karch and Lasagna algorithm (unrelated, unlikely, possible, probable, definite) and the further measures taken. RESULTS: 111 patients met the inclusion criteria, with a mean age of 56.06 years (SD: 12.12), 90 of them women (81.1%) and mean time since diagnosis of the disease of 11.97 years (SD: 7.95). 24 patients (21.6%) had a history of allergy. 12 adverse events were observed in 7 patients, 9 of which at the time of administration and 3 in 24 hours after. There were no serious adverse events and only one of the adverse events (AEs) was rated as moderate (urticaria). The remaining AA were mild.
