The data project: a shared approach between stakeholders of the healthcare system in definition of a therapeutic algorithm for inflammatory arthritis.

Rheumatic musculoskeletal diseases or RMD [rheumatoid arthritis (RA) and spondyloarthritis (SpA)] are systemic inflammatory diseases for which there are no biomarkers capable of predicting treatments with a higher likelihood of response in naive patients. In addition, the expiration of the anti-TNF blocking drugs' patents has resulted in the availability of anti-TNF biosimilar drugs with the same efficacy and safety than originators but at significantly reduced prices. To guarantee a personalized therapeutic approach to RMD treatment, a board of rheumatologists and stakeholders from the Campania region, Italy, developed a clinically applicable arthritis therapeutic algorithm to guide rheumatologists (DATA project). The general methodology relied on a Delphi technique forecast to produce a set of statements that summarized the experts' consensus. Selected clinical scenarios were discussed in light of the available evidence, and there were two rounds of voting on the therapeutic approaches. Separate discussions were held regarding rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis. The decision-making factors for each disease were clinical presentation, demographics, and comorbidities. In this paper, we describe a virtuous process between rheumatologists and healthcare system stakeholders that resulted in the development of a shared therapeutic algorithm for RMD patients naive to bDMARDs.

Plasmapheresis in cryoglobulinemic neuropathy: a clinical study.

Mixed cryoglobulinemia (MC) and glomerulonephritis are the most important extrahepatic manifestations of chronic hepatitis C virus (HCV) infection. The clinical expression of cryoglobulinemia varies from an indolent course to the development of systemic vasculitis. The renal manifestations may range from isolated proteinuria to overt nephritic or nephrotic syndrome with variable progression towards chronic renal insufficiency. Plasmapheresis appears to be a useful adjunct to conventional therapy in the treatment of anti-GBM nephritis, severe dialysis-dependent forms of pauciimmune RPGN, cryoglobulinemia, and HUS-TTR Therapy with plasmapheresis produced a marked decrease in cryoglobulin levels and a subsequent relevant clinical improvement of cutaneous lesions and renal function. In cryoglobulinemia, plasmapheresis can be used as effective further therapy to minimize cutaneous, renal and/or neurologic involvement.

European multicentre study to define disease activity criteria for systemic sclerosis. I. Clinical and epidemiological features of 290 patients from 19 centres.

OBJECTIVE: To investigate the existence of differences among European referral centres for systemic sclerosis (SSc) in the pattern of attendance and referral and in the clinical and therapeutical approaches. METHODS: In 1995 the European Scleroderma Study Group initiated a multicentre prospective one year study whose aim was to define the disease activity criteria in SSc. During the study period each participating European centre was asked to enroll consecutive patients satisfying American College of Rheumatology criteria for SSc and to fill out for each of them a standardised clinical chart. Patients from various centres were compared and differences in epidemiological, clinical, and therapeutical aspects were analysed. RESULTS: Nineteen different medical research centres consecutively recruited 290 patients. The patients could be divided into two subgroups: 173 with the limited (lSSc) and 117 with the diffuse (dSSc) form of the disease. The clinical and serological findings for the series of 290 patients seemed to be similar to data previously reported. However, when the data were analysed to elicit any differences between the participating centres, a high degree of variability emerged, in both epidemiological and clinical features and in the diagnostic and therapeutic approaches to the disease. CONCLUSIONS: The clinical approach to SSc, not only in different countries but also in different centres within the same country, is not yet standardised. To overcome this problem, it will be necessary for the scientific community to draw up a standardised procedure for the management of patients with SSc. This would provide a common research tool for different centres engaged in research on this complex disease.

Proximal stomach function in systemic sclerosis: relationship with autonomic nerve function.

Gastrointestinal involvement is frequent in patients with systemic sclerosis (SSc); however, studies on the proximal stomach and its regulation are lacking. It has been hypothesized that the primary event in the pathogenesis of gastrointestinal involvement in SSc is an early neural lesion. This study investigates proximal stomach function and its relation to autonomic nerve function in SSc. Twenty SSc patients classified in to clinical subsets, underwent measurement of proximal stomach function with and without glucagon by electronic barostat and an assessment of autonomic nerve function. SSc patients were not significantly different from 11 controls for gastric compliance (59.5+/-5.0 vs 47.7+/-4.2 ml/mm Hg, P = 0.1). The pressure-volume curves in each participant with and without glucagon were significantly different (P < 0.001). A significant positive association was found between gastric compliance and autonomic nerve function (P < 0.05). The change in gastric compliance during glucagon administration was significant-associated with autonomic function (P < 0.05). The perception cumulative scores did not differ between SSc patients and control subjects (P = 0.2). In conclusion, proximal stomach function is associated with autonomic nerve function in SSc patients. This confirms the frequent association of motility disorders with autonomic dysfunction in SSc.

Vesical telangiectasias as a cause of macroscopic hematuria in systemic sclerosis.

A 36-year-old female with diffuse cutaneous systemic sclerosis (dcSSc) developed macrohematuria due to vesical telangiectasias that was responsive to diathermocoagulation of the vasal lesions. This is the first report of a patient with dcSSc and vesical telangiectasias leading to severe macrohematuria that was successfully treated with diathermocoagulation.

Right ventricular diastolic abnormalities in systemic sclerosis. Relation to left ventricular involvement and pulmonary hypertension.

OBJECTIVES: To investigate right ventricular diastolic function in systemic sclerosis (SSc) and its relation to clinical features of the disease. METHODS: Seventy seven unselected SSc patients and 33 healthy subjects were submitted to echocardiography and echo Doppler study to assess left and right systolic as well diastolic function and to estimate maximal arterial systolic pulmonary pressure (PAP). In addition, the patients were investigated to define the SSc subset and the extent of skin and internal organ involvement. RESULTS: An abnormal right ventricular filling, as expressed by an inverted tricuspidal (Tr) E/A ratio (Tr E/A ratio <1), was detected in 31 of the 77 SSc patients (40%) and in 0 of the 36 controls ( p<0.001 ). All the 31 patients with an inverted Tr E/A ratio were found to have a PAP > 30 mm Hg. Twenty resulted to have an inverted mitral (Mit) E/A ratio (Mit E/A ratio <1), indicating an abnormal left ventricular filling. In multiple regression analysis, Tr E/A ratio resulted to be independently correlated to both PAP (r= -0.35;p<0. 003) and Mit E/A ratio (r=0.39;p<0.001). CONCLUSIONS: This study points out an impaired right ventricular filling in a significant percentage of SSc patients whatever the subset. This alteration is independently correlated to both PAP and left ventricular filling abnormalities.

[Mouth opening in patients with systemic sclerosis: base analysis and during follow-up]. / L'apertura della bocca in pazienti con sclerosi sistemica: analisi basale e in corso di follow-up.

BACKGROUND: A large number of orofacial abnormalities have been described in patients with Systemic Sclerosis (SSc) but no data are reported on the correlation with different subgroups of patients on the efficacy of different therapies. METHODS: In the present study mouth opening was retrospectively evaluated in 40 patients with SSc in whom measurement of interlabial distance was taken at the first clinical control and during follow-up. The data confirmed that the mouth opening is significantly decreased in patients with SSc independently from sclerosis subgroup, age or disease duration. RESULTS: Follow-up (8 +/- 8.3 years) showed a different behaviour of the parameter: in 12 patients (group I) no variation in mouth opening was detected, in 18 patients (group II) a decrease and in 10 patients (group III) an increase was observed. CONCLUSIONS: The only difference between the three groups was the treatment received: 80% of the patients of group III (p < 0.01) have been treated with cyclophosphamide (CF). Our data further support the efficacy of treatment with CF in patients with SSc.

Scleroderma renal crisis analysis of prevalence and outcome in a large italian series.

During a 30-year period, 323 SSc patients were admitted to a tertiary center specialized in connective tissue diseases. Among them 13 (4|X%) developed scleroderma renal crisis (SRC). These 13 SRC patients with respect to the remaining SSc patients were older, were more often affected by diffuse cutaneous systemic sclerosis (dcSSc), and had slightly higher blood pressure and more frequent heart involvement at initial presentation. Among the 13 SRC patients, an older age, a shorter disease duration, and a higher peak serum creatinine correlated with a poor outcome.SRC in Italian patients showed a lower prevalence (4|X%) than in many earlier reports. Mean survival in SRC patients was 6 years. This tended to be less than the 16.5 years for all others, but this trend was not statistically significant at least for those admitted in the post-captopril era.From a clinical point of view, the higher prevalence of later SRC in dcSSc patients presenting with mild arterial hypertension and or heart involvement is worth noting. Many patients were asymptomatic and were detected only on a routine visit. Such patients must be carefully followed to detect any early finding of SRC.

Diastolic abnormalities in systemic sclerosis: evidence for associated defective cardiac functional reserve.

OBJECTIVE: To investigate the pattern of diastolic abnormalities in patients with systemic sclerosis (SSc) and the relationship between impaired ventricular filling and systolic function. METHODS: Twenty four patients with SSc underwent M-mode and two dimensional echocardiography using echo-Doppler and gated blood pool cardiac angiography, both at rest and after exercise. RESULTS: An impaired diastolic relaxation of the left ventricle was detected in 10 of the 24 patients with SSc. Left ventricular ejection fraction at rest in these 10 patients with impaired ventricular filling did not differ from that in the remaining 14 patients, but eight of the 10 failed to increase their ejection fraction during exercise, compared with two of the 14 with normal ventricular filling (p = 0.003). CONCLUSION: Impaired relaxation of the left ventricle is a recently described feature of scleroderma heart disease. Diastolic dysfunction in SSc could depend on myocardial fibrosis or myocardial ischaemia, or both. It was found to be associated with a defective cardiac functional reserve. However, its prognostic significance remains to be clarified.
