RESUMO

The term "rhupus" is traditionally used to describe patients with coexistence of systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). The aim of the present work was to investigate prevalence, clinical and radiological picture as well as the serological profile of a series of rhupus patients; SLE patients and RA patients from our Unit were used as disease control groups. A total of 103 consecutive SLE patients were screened; among the entire cohort, 10 patients (9.7%) were classified as "rhupus". In our rhupus patients SLE features preceded the onset of arthritis in 5 patients (50%) while in the remaining patients arthritis appeared before or simultaneously (3 and 2 patients respectively). As compared with SLE patients, rhupus patients have significantly less kidney involvement (p=0.01) while no differences were observed between neuropsychiatric, cutaneous, hematological involvement or serositis. At our physical examination, 9 (90%) rhupus patients were presenting active joint involvement; CRP positivity and ESR levels resulted significantly higher than in SLE (p=0.006) patients while no differences were observed with respect to RA patients. In all rhupus patients, at least one pathological finding was revealed by ultrasound (US) examination at wrist and/or hand joints; overall, rhupus patients presented higher scores in all the US parameters with respect to SLE patients, especially at hands; no statistically significant differences have been observed with respect to RA patients. Magnetic resonance (MR) revealed erosions in all rhupus patients with a concomitant bone edema in five patients. The cumulative erosive burden in rhupus patients was significantly higher than in SLE patients and similar to RA patients (SLE vs rhupus p=0.005); bone pathology distribution was also similar between rhupus patients and RA patients. These data suggest the importance of assessing joint involvement in SLE with advanced imaging techniques and of evaluating the presence of prognostic factors for joint disease severity in order to establish adequate disease monitoring and to institute early appropriate therapies to avoid late consequences of unrecognized concomitant rheumatoid arthritis (Amezcua-Guerra et al., 2006 [25]; Zhao et al., 2009 [26]).

RESUMO

Fibromyalgia syndrome (FMS) is a common form of non-inflammatory rheumatism within the general population with symptoms often mimicking those of arthritis or muscle disorders. Arthralgic symptoms in the region of the hip are commonly mentioned by patients with FMS and one of the diagnostic trigger points for the condition is found around the greater trochanter. To date, no formal imaging studies using ultrasound (US) have been performed in FMS. This study describes the correlation between clinical and US findings in patients presenting with primary FMS to rheumatology clinics. In the majority of the patients, no significant pathological US abnormalities were detected.

RESUMO

OBJECTIVES: To investigate the prevalence of ultrasound (US) detectable inflammation in hips of patients with ankylosing spondylitis (AS) and the relationship between US and measures of disease activity and severity. METHODS: Consecutive patients with AS attending the rheumatology units involved in this study were enrolled. Clinical and demographical data were recorded. US examination of bilateral hips was performed at the same time, evaluating anterior longitudinal scan to search for synovial hypertrophy (SH), joint effusion (JE) or power Doppler (PD) positive synovitis. RESULTS: A total of 56 patients were included, median age (interquartile range, IQR) 49 (39, 59.5), median disease duration 98 (72, 204) months, 80.3% were treated with TNF-α inhibitors, median BASDAI 2.65 (1.96, 3.95), 30.3% had hip tenderness. US JE was found in 26.7% of patients, US SH in 16%, no patient had detectable PD. The concordance between clinical findings and US abnormalities was moderate, with a kappa of 0.44. Patients with detectable US abnormalities had higher median visual analogue scale (VAS) pain and C-reactive protein (CRP), while there was no significant association with other measures of disease activity and disability. In the subgroup of patients with no hip tenderness, US alterations were still significantly related to higher CRP levels, while in patients with hip tenderness and no US abnormalities CRP was not higher than in the asymptomatic patients. CONCLUSIONS: US assessment of hip joint in AS patients can be considered of value, as suggested by the correlation with relevant clinical and laboratory measures. In asymptomatic patients, US examination might provide further information on subclinical involvement.

RESUMO

The foot is increasingly the focus of attention for rheumatologists when assessing patients presenting to a clinic and may represent underlying intra-articular inflammatory pathology or involvement of the surrounding soft tissues. This study describes the correlation between clinical and ultrasound (US) findings in patients presenting with a variety of rheumatic disorders linked with foot pain. Poor correlation was found between conventional clinical examination and US in cases with joint inflammation, tendonitis and, more particularly, those cases with enthesopathy.

RESUMO

OBJECTIVES: To investigate the ability of ultrasonography (US) to detect synovitis in metatarsophalangeal joints (MTP) in patients with suspicion of early arthritis, and to discriminate between diagnoses. METHODS: Patients referred to early arthritis clinics for differential diagnosis were enrolled, and clinical and laboratory measures were recorded. Ultrasonography of MTPs was performed searching for synovial hypertrophy (SH), joint effusion (JE) and power Doppler (PD), graded from 0 to 3 on a semi-quantitative scale. Patients were classified according to definite classification criteria, or as undifferentiated arthritis or non-inflammatory pathology. US findings were compared across different diagnoses and diagnostic accuracy was calculated taking clinical diagnosis as reference. RESULTS: Out of 427 patients (71% rheumatoid arthritis (RA), 20% undifferentiated arthritis (UA), 15% spondyloarthritides (SpA), 13% non-inflammatory), 307 (71.9%) showed SH, 120 (25.5%) JE, 77 (18.0%) PD. RA patients had median JE, SH and PD scores significantly higher than non-inflammatory and other diseases. Patient with UA and SpA had higher scores of SH and JE compared to non-inflammatory, no significant differences were present among different diagnosis. In RA, SH and JE were more frequently detected in the second MTP, and PD in the fifth. Crystal-related arthritis showed a tendency towards a more frequent involvement of the first MTP. The diagnostic accuracy of single US measures was moderate, but the detection of a PD of 2 or more provided a high specificity for the diagnosis of RA. CONCLUSIONS: US can be used as additional information in patients evaluated in an early arthritis setting. High scores of JE, SH and PD, together with the pattern of involvement are suggestive of RA.

RESUMO

Psoriatic arthritis (PsA) is an arthropathy associated with psoriasis, which is part of the spondyloarthropathy family, and which may present with various forms, from mono-oligoarthritis to symmetric polyarthritis mimicking rheumatoid arthritis. In longstanding disease, the symmetric polyarthritis is the most common pattern of PsA, involving the small joints of hands, feet (the involvement of which seems to be very common, ranging from 50 to 100% of patients), wrists, ankles and knees. Other common features are represented by the inflammation of enthesis and tendons. Its exact prevalence, in Italy, should be about 30% in psoriatic subjects or 0.42% when considering the general population. The aims of our study were to investigate, by US examination, the prevalence and the features of foot involvement in PsA and to describe their correlations with clinical findings. Ultrasound (US) examinations were performed using a Logiq 9 (General Electric Medical Systems, Milwaukee, WI) equipped with a multifrequency linear probe, working at 14 MHz. One hundred and eighty feet were investigated in a total of 101 patients. Prior to US assessment, all patients underwent a clinical examination by an expert rheumatologist who recorded the presence/absence of pain, tenderness (detected by palpation and/or active or passive mobilisation of the feet) and swelling. US finding indicative of metatarsophalangeal joint inflammation were obtained in 77 (76.2%) patients, while only 34 (33.7%) patients were positive to the clinical examination. This study demonstrates that US detected a higher number of inflamed joints with respect to clinical assessment in PsA patients.

RESUMO

OBJECTIVES: To investigate the prevalence and severity of sonographic-detected abnormalities in knee osteoarthritis (OA) and to correlate ultrasound (US) findings with clinical data. METHODS: Outpatients with chronic, painful knee OA according to the ACR criteria were consecutively recruited and underwent clinical and US examinations. An expert rheumatologist recorded the presence of knee joint pain, swelling and tenderness, patient's global assessment of knee pain using visual analogue scale (VAS), and Lequesne Index of severity for knee OA. A second rheumatologist, blinded to the clinical data, performed the knee US examination using a Logiq9 machine equipped with a 12MHz linear probe and registering the presence of joint effusion, synovial proliferation, power Doppler (PD) signal, Baker's cyst, osteophytes and femoral cartilage abnormalities. RESULTS: One hundred and sixty-four knees of 82 patients (53 women, 29 men) were studied; mean age was 63.2±8.1 SD years, mean disease duration was 4.3±5.6 SD years. All patients complained of at least one knee joint pain during physical activity. Mean patient's VAS for knee pain was 48.4±19.9 SD mm, mean Lequesne Index was 8.2±4.4 SD. Knee swelling was present in 39% of the patients and tenderness was found in 65.8%. US showed: joint effusion in 43.3% of the patients, synovial proliferation in 22.1%, PD signal in 2.9%, Baker's cysts in 6.6%, cartilage abnormalities in 79%, osteophytes in 100%. In all patients US findings were present at least at the level of one knee. Statistically significant correlations were demonstrated between a composite inflammatory score and both VAS (p=0.004) and Lequesne Index (p<0.0001). CONCLUSIONS: This US study showed both inflammatory abnormalities and structural damage lesions in knee OA. Interestingly, statistically significant correlations were demonstrated between US inflammatory findings and the main clinical tests for OA, confirming that sonography has a relevant role in the global evaluation of patients with knee OA.

RESUMO

Psoriatic arthritis (PsA) is an arthropathy associated to psoriasis, which is part of the spondyloarthropathy family, and which may present with various forms, from mono-oligoarthritis to symmetric polyarthritis mimicking rheumatoid arthritis. In longstanding disease, the symmetric polyarthritis is the most common pattern of PsA, involving small joint of hands, feet, wrists, ankles and, very frequently, knees. Other common features are represented by the inflammation of enthesis and tendons. Ultrasound (US) examinations were performed using a Logiq 9 (General Electric Medical Systems, Milwaukee, WI) equipped with a multifrequency linear probe, working at 10-14 MHz. One-hundred and sixty-six knee joints were investigated in a total of 83 patients. Prior to US assessment, all patients underwent a clinical examination by an expert rheumatologist who recorded the presence/absence of pain, tenderness (detected by palpation and/or active or passive mobilisation of the knee), and knee swelling. Sixty-two (74.7%) knee joints were found clinically involved, while at least one US finding indicative of joint inflammation was obtained in 70 (84.3%) knee joints. In the 59% of the patients we noticed synovial hypertrophy. Enthesitis was present in 39.7% of the subjects studied. This study demonstrated that US detected a higher number of inflamed knee joints and enthesis with respect to clinical assessment in PsA patients.

RESUMO

The knee is a frequent target for gout and calcium pyrophosphate dihydrate (CPPD) disease with involvement of both articular and peri-articular structures. The aims of the present study were to investigate the relationship between clinical and ultrasound (US) findings and to describe the prevalence and distribution of crystal deposits in the knee in patients with gout and CPPD disease. Thirty patients with gout and 70 patients with CPPD disease were enrolled in the study. Prior to US assessment all patients underwent a clinical examination by an expert rheumatologist who recorded the presence/absence of pain, tenderness (evocated by palpation and/or active or passive mobilisation of the knee), and knee swelling. US examinations were performed using a Logiq 9 (General Electric Medical Systems, Milwaukee, WI) equipped with a multifrequency linear probe, working at 9 MHz. Two hundred knee joints were investigated in a total of 100 patients. Fifty-one (25.5%) knee joints were found clinically involved, while at least one US finding indicative of joint inflammation was obtained in 73 (36.5%) knee joints.The most frequent US finding indicative of knee joint inflammation was joint effusion, detected in 21 (35%) out of 60 knees and in 52 (37%) out of 140 knees, in gout and CPPD disease, respectively. Ten (17%) out of 60 knees and 21 (15%) out of 140 knees were found positive for synovial hypertrophy with or without intra-articular power Doppler, in gout and CPPD disease respectively. Sonographic evidence of crystal deposition within joint cartilage (hyaline and fibrocartilage) was more frequently seen than in the soft tissue in the knee.This study demonstrated that US detected a higher number of inflamed knee joints than clinical assessment in patients with crystal related arthropathies and that the distribution of crystal deposits at joint cartilage level permitted distinction between gout and CPPD disease. Further studies are required to investigate both sensitivity and specificity of US features indicative of crystal aggregates at both tendon and entheseal level.

RESUMO

The knee joint is a frequent focus of attention for rheumatologists when assessing patients presenting to a clinic and may represent underlying intra-articular inflammatory pathology or involvement of the surrounding soft tissues. This study describes the correlation between clinical and ultrasound findings in patients presenting with a variety of rheumatic disorders and knee pain. US imaging provides for a sensitive and detailed identification of different intra- and peri-articular pathology responsible for knee pain.

RESUMO

In the rheumatology literature, most of the available evidence on three-dimensional ultrasound (3D US) is related to the acquisition process and highlights the virtual operator independence and shortening of the US examination time. The main aim of this study was to compare 3D US using a high-frequency volumetric probe and conventional 2D US at the wrist and hand in patients with rheumatoid arthritis (RA). The 3D US examinations were performed using a Logiq 9 (General Electrics Medical Systems, Milwaukee, WI) with a high-frequency (8-15 MHz) volumetric probe. Overall, there is good-to-excellent agreement between the two modalities relating to both joint inflammation and bone erosion. This study is an initial step towards establishing a methodology necessary for developing multi-centre US studies which are aimed at assessing hand involvement in patients with RA.
