Structured report for chest high-resolution computed tomography in patients with connective tissue disease: Impact on the report quality as perceived by referring clinicians.

RATIONALE AND OBJECTIVES: To evaluate the impact on perceived report quality of referring rheumatologists for a chest high-resolution computed tomography (HRCT) structured report (SR) template for patients with connective tissue disease (CTD), compared to the traditional narrative report (NR). MATERIALS AND METHODS: We retrospectively considered 123 HRCTs in patients with CTD. Three radiologists, blinded to the original NRs they wrote during clinical routine, re-reported each HRCT using an SR dedicated template. We then divided all NR-SR couples into three groups (41 HRCT each). Each group was evaluated by one of three rheumatologists (R1, R2, R3), who expressed their perceived report quality for the respective pools of NRs and SRs in terms of completeness, clarity (both on a 10-points scale), and clinical relevance (on a 5-points scale). The Wilcoxon test and the McNemar test were used for statistical analysis. RESULTS: For each rheumatologist, SR received higher ratings compared to NR for completeness (median ratings: R1, 10 vs. 7; R2, 10 vs. 8; R3, 10 vs. 6, all p < 0.0001), clarity (median ratings: R1, 10 vs. 7; R2, 10 vs. 8; R3, 10 vs. 7, all p < 0.0001), and clinical relevance (median ratings: R1, 5 vs. 4; R2, 5 vs. 4; R3, 5 vs. 1, all p < 0.0001). After rating dichotomization, the use of SR led to a significant increase (p < 0.01) in completeness, clarity, and clinical relevance as compared to NR, except for clarity as perceived by R2 (p = 1). CONCLUSION: Referring rheumatologists' perceived report quality for structured reporting of HRCT in patients with CTD was superior to narrative reporting.

Potential transfer of aquatic organisms via ballast water with a particular focus on harmful and non-indigenous species: A survey from Adriatic ports.

Ballast water discharges may cause negative impacts to aquatic ecosystems, human health and economic activities by the introduction of potentially harmful species. Fifty untreated ballast water tanks, ten in each port, were sampled in four Adriatic Italian ports and one Slovenian port. Salinity, temperature and fluorescence were measured on board. Faecal indicator bacteria (FIB), phyto- and zooplankton were qualitatively and quantitatively determined to identify the species assemblage arriving in ballast water. FIB exceeded the convention standard limits in 12% of the sampled tanks. Vibrio cholerae was not detected. The number of viable organisms in the size groups (minimum dimension) <50 and ≥10 µm and ≥50 µm resulted above the abundances required from the Ballast Water Management Convention in 55 and 86% of the samples, respectively. This is not surprising as unmanaged ballast waters were sampled. Some potentially toxic and non-indigenous species were observed in both phyto- and zooplankton assemblages.

Switching to etanercept in patients with rheumatoid arthritis with no response to infliximab.

TNF-alpha is thought to play a pivotal role in the initiation and perpetuation of the chronic inflammatory process in rheumatoid arthritis. TNF-alpha blockers such as infliximab and etanercept are currently used in the treatment of active rheumatoid arthritis (RA) when traditional DMARDs have failed and are effective in a significant proportion of patients. However, about one third are non-responders to anti-TNF-alpha. The aim of this study was to verify whether rheumatoid patients, after failing infliximab, can benefit from etanercept. We analysed 18 patients with active RA with no response to at least 3 DMARDs and where infliximab therapy had failed. The patients had received infliximab associated with methotrexate: eleven of them did not show any significant response, while seven patients, after a good response, relapsed. Etanercept was then started. EULAR criteria of response were used with calculation of activity index DAS28 at baseline, after 2 weeks, 3 months and every third month until last follow-up. A moderate or good response was achieved with etanercept in 13 out of 18 patients. From our experience, etanercept can be considered as a good alternative choice when infliximab has failed.

[Neuropsychological tests, MRI and SPECT in the evaluation of CNS involvement in SLE]. / Test neuropsicologici, RMN e SPECT nella valutazione del danno cerebrale nel LES.

OBJECTIVE: To assess the agreement between presence and location of central nervous system (CNS) structural damage and neuropsychological performance. METHODS: 21 unselected SLE patients underwent a 3 hours-long battery of neuropsychological tests sampling 15 cognitive functions. A neuropsychologist hypothesized for each SLE patient the most likely site of possible involvement, according to the neuropsychological performance. Patients underwent MRI scans within 6 months (3 months before or after) from neuropsychological tests and SPECT. RESULTS: 14 of the 21 SLE patients (66.6%) were impaired in at least 1 function; among these, 7 patients (33.3%) were mildly impaired and 7 (33.3%) had more than 3 functions impaired. 10 patients (48%) had abnormal MRI scan. Negative and positive agreements between neuropsychological performance and MRI scan were detected in 15 patients (71%; ?2 with Yates' correction 6.09, p 0.007, measure K for concordance 0.44, p 0.03). All the 6 negative agreements had no records of major neurologic or psychiatric events; among the 9 positive agreements, 6 presented previous major neurologic events and 2 minor neuropsychiatric symptoms. Among the subjects with disagreement, 1 was unimpaired with positive MRI and without neuropsychiatric symptoms, 5 were mildly impaired with negative MRI. CONCLUSIONS: A detailed neuropsychological evaluation along with MRI arose as a valid method to exclude or to identify, localize and clinically interpret CNS involvement in SLE. Disagreement between MRI and neuropsychological tests was detected mainly for mild cognitive impairment that might be the expression of functional (inflammatory or ischemic) processes.

Rescue of combination therapy failures using infliximab, while maintaining the combination or monotherapy with methotrexate: results of an open trial.

OBJECTIVE: To assess the possible clinical and biological rescue of rheumatoid arthritis (RA) in 16 patients who were still active despite intensive combination therapy after receiving infliximab following the Anti-Tumour necrosis factor Trial in Rheumatoid Arthritis with Concomitant Therapy (ATTRACT) schedule. METHODS: Sixteen patients who were still active despite combination therapy with optimal doses of methotrexate (MTX 15-17.5 mg/week) and cyclosporin A (CsA 2.5-3.5 mg/day) received infliximab. Ten received their combination plus infliximab (Combi), and six received infliximab plus MTX alone (Mono). The follow-up was carried out for 30 weeks in all patients and for 46 weeks in eight. Efficacy and safety were examined. RESULTS: At entry, the mean disease activity score (DAS) was 5.6 (all patients had a DAS >3.7). After therapy, eight of 10 patients in Combi and four out of six in Mono showed an improvement of >50% in the initial swollen joint count, yet only one patient reached 50% improvement in the initial DAS after 30 weeks, and one patient had a DAS <2.4 (low disease activity). Of the eight patients who reached 46 weeks of follow-up, three showed an improvement in DAS of 50% and two had a DAS <2.4. When considering the change over time, the difference between DAS at entry and at week 30 was statistically significant only in patients receiving MTX plus CsA, while it was not significant in those receiving MTX only. Two patients developed recurrent febrile upper respiratory infections in the Combi therapy group, while two had a single febrile infection in the MTX alone group. Two patients became strongly anti-cardiolipin positive (IgM >40 MPL) and one developed a coronary syndrome. CONCLUSION: Infliximab can be added incrementally to MTX plus CsA, with favourable results in terms of efficacy and safety over time in severe rapidly aggressive and progressive RA. Finally, minor evidence emerged for a stronger efficacy of the Combi treatment compared with Mono.

Analysis of improvements, full responses, remission and toxicity in rheumatoid patients treated with step-up combination therapy (methotrexate, cyclosporin A, sulphasalazine) or monotherapy for three years.

OBJECTIVE: To evaluate two monotherapies followed by step-up combination therapy with two or three complementary drugs in active rheumatoid arthritis (RA) in comparison with sulphasalazine (SSZ) alone. METHODS: One hundred and twenty-six consecutive patients with early active RA were enrolled in this open controlled clinical trial. The primary end-point was 50% improvement according to the ACR criteria (ACR50) at 6, 12 or 18 months. The secondary end-points were a full response (Magnusson criteria) and/or remission (ACR criteria) at 3 yr. Methotrexate (MTX) (group 1), cyclosporin A (CsA) (group 2) or SSZ (group 3) was used first. After 6 months, a combination of two drugs (CsA and MTX) was employed in groups 1 and 2. SSZ was added after 12 months if improvement was less than ACR50 with the combination. Group 3 continued with SSZ alone. RESULTS: After 6 months, 57% of patients in group 1, 31% of group 2 (MTX vs CsA, P=0.002) and 33% of group 3 (MTX vs SSZ, P=0.01) had reached ACR50 improvement according to intention-to-treat analysis. At month 12 after starting a drug combination, 67% of group 1 and 76% of group 2 had reached ACR50 compared with 24% of group 3. At the 18-month follow-up, 90% of group 1 and 88% of group 2 but only 24% of group 3 had reached ACR50. After 18 months, 62% of group 1, 60% of group 2 and 48% of group 3 showed side-effects and three, five and eight patients in the three groups respectively had dropped out of the study. At the 3-yr follow-up, 9% of the patients in groups 1 and 2 and 7% of group 3 were in remission according to the ACR criteria; according to the Magnusson criteria, 40% showed a full response in groups 1 and 2 but only 21% did so in group 3. CONCLUSION: MTX appears to be the fastest-acting agent. A step-up approach with MTX plus CsA plus SSZ led to a 50% improvement according to the ACR criteria in most patients. After 3 yr, 40% of patients receiving combination therapy and 21% of patients receiving monotherapy showed a full response, while 9 and 7% respectively attained remission.

[TNF- alpha gene polymorphisms in rheumatoid arthritis patients treated with anti-TNF-alpha agents: preliminary results]. / Polimorfismi del gene del TNF-alpha in pazienti con artrite reumatoide trattati con biologici anti-TNF-alpha: risultati preliminari.

OBJECTIVES: To study -238 and +489 TNF-alpha polymorphisms in severe-unresponsive (more than 6 swollen joints and still active disease despite at least 6 months of DMARDs combination therapy) and mild-responsive (less than 3 swollen joints and good response to MTX or other conventional DMARDs) rheumatoid arthritis (RA). METHODS: We investigated 100 RA patients (56 with severe and 44 with mild disease activity) and 45 healthy blood donors (HBDs). Genotyping was performed by PCR-restriction fragment length polymorphism procedure. Several clinical and serological parameters were also examined. RESULTS: Severe RA patients disclosed the -238 GG genotype in 100% of the cases versus 95.5% in the mild-responsive patients and 91.2% in the HBDs. The +489 GG genotype disclosed only a trend towards a prevalence in severe RA patients. However the +489 A allele seems to associates with early onset, longer disease duration and longer responsiveness to conventional therapy. CONCLUSION: The -238 AG genotype is absent in severe-unresponsive RA, but present in mild-responsive RA subjects. Thus -238 GG homozygosity associates with severity and unresponsiveness. In contrast the +489 polymorphism does not segregate differently between responsive and unresponsive RA patients.

Anticardiolipin antibodies in rheumatoid patients treated with etanercept or conventional combination therapy: direct and indirect evidence for a possible association with infections.

OBJECTIVE: To assess the occurrence of anticardiolipin antibodies (ACA) (as well as of anti-DNA antibodies) in patients with rheumatoid arthritis treated with etanercept or combination therapy. METHODS: Eight patients treated with etanercept 25 mg twice weekly were studied for a period of 85 weeks. A control group of 39 patients with rheumatoid arthritis undergoing combination treatment (methotrexate (MTX) + cyclosporin A or MTX + chloroquine) were studied for the same period of time. The occurrence of anticardiolipin antibodies (ACA-IgG) and anti-DNA was examined, together with the possible occurrence of infections due to bacteria capable of inducing B cell activation. RESULTS: In 5/8 patients receiving etanercept an increase of ACA-IgG was seen, while anti-DNA became positive in 3/8 patients. A nasal or bronchial infection due to Staphylococcus aureus (Staph aureus) or a urinary tract infection due to E coli, occurred in all five cases. Antibiotic treatment produced a return to normal of ACA-IgG, and also of anti-DNA, in all cases except one. The infectious agent was eradicated in all subjects but one. In the control group Staph aureus was found in the nasal swab in 10/39 subjects; ACA-IgM (followed by ACA-IgG) appeared at the same time as infection occurred in 6/10, while no infection related to the increased ACA-IgM was recorded in the other four. CONCLUSIONS: Bacterial DNA, especially that enriched in CpG motifs, is a powerful immunostimulant that may, in some cases, lead to ACA or anti-DNA positivity, once tumour necrosis factor alpha is blocked. Eradication of the infections leads to a rapid decrease of ACA-IgG and of anti-DNA levels.

Steroid sparing therapeutic approaches to polymyalgia rheumatica-giant cell arteritis. State of the art and perspectives.

The therapeutic approach to polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) remains mainly based on corticosteroids. A few studies in PMR suggest a steroid-sparing effect with methotrexate in a subset of patients. No real alternative to steroids exists in GCA. Given the high chance of long-term treatment with corticosteroids in both diseases, randomized controlled trials with new immunosuppressive steroid-sparing drugs are eagerly awaited.

Changes in regional cerebral blood flow after a cold hand test in systemic lupus erythematosus patients with Raynaud's syndrome.

The appearance of vasospastic features in the central nervous system (CNS) after a cold stressor test was Investigated through single photon emission computed tomography (SPECT) of regional cerebral blood flow in patients with systemic lupus erythematosus, with and without Raynaud's syndrome, and in scleroderma patients. We have shown that Raynaud's syndrome may occur in the CNS and that anticardiolipin or lupus anticoagulant positivity may favour perfusion defects.

Circulating levels of interleukin 10 and other cytokines in rheumatoid arthritis treated with cyclosporin A or combination therapy.

OBJECTIVE: To assess longitudinally over a 12 month period circulating serum levels of interleukin 10 (IL-10) and cytokines IL-3, IL-4, IL-6, and IL-12 in a cohort of patients with early onset rheumatoid arthritis (RA) treated with either cyclosporin A (CyA) or with combination therapy of CyA plus hydroxychloroquine as disease modifying antirheumatic drugs. METHODS: We studied 8 patients receiving CyA and 12 patients receiving CyA plus hydroxychloroquine. IL-3, IL-4, IL-6, IL-10, and IL-12 were determined by ELISA at entry, after 2 weeks, after one month, after 6 months, and after 12 months. Rheumatoid factor levels and the possible appearance of monoclonal gammopathies over time were studied by immunofixation and immunoblotting techniques. RESULTS: The pooled data show that at entry only the median baseline levels of IL-10 (3.9 vs 1.6 pg/ml; p < 0.01) and IL-6 (16.9 vs 1.4 pg/ml, p < 0.001) were higher in patients than in controls. IL-4 was not detectable. Some patients at entry (those with the longest disease duration) had detectable levels of IL-3. Only levels of IL-10 decreased significantly between entry and final values, in monotherapy and combination therapy as well. A single transient monoclonal band was observed after 6 months of treatment, which disappeared afterwards. No difference was seen in any of the cytokines between the CyA and the CyA plus hydroxychloroquine treated patients. CONCLUSION: During treatment with either CyA or CyA plus hydroxychloroquine, IL-10 levels decreased significantly. No additive effect of the 2 drugs was detected.

High dose intravenous immunoglobulin therapy for rheumatic diseases: clinical relevance and personal experience.

The actual efficacy and applicability of high dose intravenous immunoglobulin (IVIG) therapy in the rheumatic disorders is still being debated. In the last few years clinical results have become available on a large number of patients, and efforts have been devoted to experimental studies of the mechanism of action of IVIG. However, the results of controlled clinical trials will be crucial to indicate stricter guidelines and directions for future clinical and experimental research. IVIG is of major value in Kawasaki disease and in severe lupus-associated thrombocytopenia. Its possible benefits are also remarkable in refractory dermatomyositis and probably in some patients with the antiphospholipid syndrome and recurrent miscarriages despite standard treatment. At present, the role of IVIG therapy remains controversial in lupus nephritis and in systemic vasculitis, while it does not seem to be effective in rheumatoid arthritis.

Abnormalities of autonomic nervous system in hyperadrenergic orthostatic hypotension: description of a case.

Hyperadrenergic orthostatic hypotension was diagnosed in a 27-year-old man because of recurrent episodes of hypotension associated with high plasma noradrenaline levels. In this patient, laboratory tests were performed to evaluate autonomic nervous system function. Decreased response to Valsalva maneuver and carotid sinus massage indicated decreased baroreflex and vagal responsiveness, respectively. Cardiovascular response to the handgrip was reduced in comparison to controls. Passive leg raise showed normal reduction of plasma norepinephrine, indicating normal responsiveness of cardiopulmonary receptors. 'Non-dipper' profile in the ambulatory blood pressure monitoring provided further evidence for an impaired autonomic control of cardiovascular function in this patient. This report suggests the presence of autonomic dysfunction in hyperadrenergic orthostatic hypotension.
