The challenge of the definition of early symptomatic knee osteoarthritis: a proposal of criteria and red flags from an international initiative promoted by the Italian Society for Rheumatology.

The aim of this study was to establish consensus for potential early symptomatic knee osteoarthritis (ESKOA) clinical definition and referral criteria from primary care to rheumatologists, based on available data from literature and a qualitative approach, in order to perform studies on patients fulfilling such criteria and to validate the obtained ESKOA definition. A complex methodological approach was followed including: (1) three focus groups (FG), including expert clinicians, researchers and patients; (2) a systematic literature review (SLR); (3) two discussion groups followed by a Delphi survey. FG and SLR were performed in parallel to inform discussion groups in order to identify relevant constructs to be included in the modified Delphi survey. ESKOA is defined in the presence of: (a) two mandatory symptoms (knee pain in the absence of any recent trauma or injury and very short joint stiffness, lasting for less than 10 min, when starting movement) even in the absence of risk factors, or (b) knee pain, and 1 or 2 risk factors or (c) three or more risk factors in the presence of at least one mandatory symptom, with symptoms lasting less than 6 months. These criteria are applicable in the absence of active inflammatory arthritis, generalized pain, Kellgren-Lawrence grade >0, any recent knee trauma or injury, and age lower than 40 years. Knee pain in the absence of any recent trauma lasting for less than 6 months was considered as the referral criterion to the rheumatologist for the suspicion of ESKOA. This consensus process has identified provisional clinical definition of ESKOA and defined potential referral criterion to rheumatologist, in order to test ESKOA obtained definition in prospective validation studies.

Ultrasonographic wrist and hand abnormalities in early psoriatic arthritis patients: correlation with clinical, dermatological, serological and genetic indices.

OBJECTIVES: The aims of our study are to describe the wrist and hand ultrasound (US) abnormalities compared to clinical examination in early psoriatic arthritis (ePsA) and to analyse their correlation with clinical, dermatological, serological and genetic indices. METHODS: We analysed 1120 fingers and 224 wrists of 112 early PsA, with MyLab70 Xview (Esaote, linear probe) ultrasound (US). Power Doppler active synovitis (AS), erosions, finger tendons tenosynovitis or peritendinitis (TP) and pseudotenosynovitis (PT), were compared to clinical (BASDAI, SHAQ), dermatological (PASI and psoriasis aspects), serological (ESR, CRP, ACPA) and genetic (HLA haplotypes) indices. RESULTS: All US abnormalities were present: AS was more frequent at wrists (50/224 [22.3%]), followed by hand PT (68/1120 [6,1%]) and TS (29/1120 [2.6%]), while erosions were rare (10/1120 [0.8%]). US abnormalities were independent of ePsA clinical indices (except erosions - even if represented only in a low percentage - that correlated to BASDAI [p<0.05]), while they were associated to several dermatological (except PASI), serological and genetic parameters: psoriasis (all p<0.0001), palmoplantar psoriasis (wrist and hand AS p<0.0005 and p<0.005, respectively), hand psoriasis (all p<0.0001), nail dystrophy (hand AS p<0.05, PT p<0.0001, erosions p<0.0001); positive CRP (all p<0.0001), ESR (wrist and hand AS p<0.005 and <0.0005, respectively, TS, PT and erosions p<0.0001) and ACPA - even if represented only in 1.78% of patients - (wrist and hand AS and TS p<0.0001, PT p<0.5); HLA-B27 (wrist and hand AS p<0.0001, TS p<0.01, PT p<0.05), -B35 (wrist and hand AS p<0.01 and p<0.05, respectively), -B38 (wrist and hand AS p<0.0001, TS p<0.0001, PT p<0.005), -CW6 (wrist AS p<0.05), -DR4 (wrist and hand AS p<0.0001, TS p<0.0001, PT p<0.005). CONCLUSIONS: US abnormalities of hand and wrist were independent of clinical ePsA indices (except erosions), while they correlated to dermatological (except PASI), serological and genetic parameters of disease.

Ultrasound detects occult entheseal involvement in early psoriatic arthritis independently of clinical features and psoriasis severity.

OBJECTIVES: Entheseal involvement is a frequent and distinctive feature of psoriatic arthritis (PsA), and is often under-diagnosed. The aim of the present study is to investigate using ultrasound (US), lower limb entheseal abnormalities in patients with early psoriatic arthritis (ePsA) and to evaluate their correlation with ePsA clinical characteristics. METHODS: Ninety-two ePsA patients (with duration of symptoms less than 1 year), diagnosed according to CASPAR criteria, were consecutively scored with Glasgow Ultrasound Enthesitis Scoring System (GUESS) and Power Doppler (PD) US (My Lab 70 Esaote) of lower limbs entheses (quadriceps, patellar, achilles tendons and plantar fascia). Patients were clinically examined by palpation of lower limbs entheses, Maastricht Ankylosing Spondylitis Enthesitis Index (MASES) and total Psoriasis Area and Severity Index (PASI). Correlations were investigated between GUESS and PD with other ePsA clinical characteristics (duration of symptoms and morning stiffness, pain and fatigue visual analogue scale [VAS], Health Assessment Questionnaire SpA-modified [S-HAQ]). RESULTS: All patients had GUESS>1 and 40.2% showed positive PD signal on entheses, at a higher percentage than tenderness revealed by clinical examination (29.3%). GUESS and PD did not correlate with MASES, PASI and other clinical characteristics. No significant differences in GUESS and PD were detected between positive or negative findings of MASES and PASI. CONCLUSIONS: US detects subclinical entheseal involvement in ePsA, independently of ePsA clinical examination and symptoms.

Ultrasound discloses entheseal involvement in inactive and low active inflammatory bowel disease without clinical signs and symptoms of spondyloarthropathy.

OBJECTIVE: To investigate the presence of lower limb entheseal abnormalities in IBD patients without clinical signs and symptoms of SpA and their correlation with IBD clinical variables. METHODS: A total of 81 IBD patients [55 Crohn's disease (CD) and 26 ulcerative colitis (UC), 43 females and 38 males, mean age 41.3 (12.4) years, BMI 24 (2)] with low active (12) and inactive (67) disease were consecutively studied with US (LOGIQ5 General Electric 10-MHz linear array transducer) of lower limb entheses and compared with 40 healthy controls matched for sex, age and BMI. Quadriceps, patellar, Achilleon and plantar fascia entheses were scored according to the 0-36 Glasgow Ultrasound Enthesitis Scoring System (GUESS) and power Doppler (PD). Correlations of GUESS and PD with IBD features [duration, type (CD/UC) and activity (disease activity index for CD/Truelove score for UC)] were investigated. The intra- and inter-reader agreements for US were estimated in all images detected in patients and controls. RESULTS: Of the 81 patients, 71 (92.6%) presented almost one tendon alteration with mean GUESS 5.1 (3.5): 81.5% thickness (higher than controls P < 0.05), 67.9% enthesophytosis, 27.1% bursitis and 16.1% erosions. PD was positive in 13/81 (16%) patients. In controls, US showed only enthesophytes (5%) and no PD. GUESS and PD were independent of duration, activity or type (CD/UC) of IBD. The intra- and inter-reader agreements were high (>0.9 intra-class correlation variability). CONCLUSIONS: US entheseal abnormalities are present in IBD patients without clinical signs and symptoms of SpA. US enthesopathy is independent of activity, duration and type of gut disease.

Left ventricular hypertrophy in chronic kidney disease. Is pulse pressure an independent risk factor?

BACKGROUND: The study's aim was to evaluate the relations between pulse pressure (PP), hypertension and anemia with left ventricular hypertrophy (LVH). MATERIALS AND METHODS: The risk factors and prevalence of LHV were evaluated in 111 patients with CRF. RESULTS: LVH was diagnosed in 81.9% of all patients. The prevalence of hypertension was 72.6%. Anemia was present in all patients. Of the variables tested lower levels of hemoglobin, systolic blood pressure (SBP) and PP predicted the occurrence of LVH. CONCLUSIONS: This study has shown a strong association between chronic kidney disease (CKD) and LVH in pre dialysis patients. Pulse pressure, SBP and anemia play an important role in the development of left ventricular hypertrophy in CKD patients.
