Abstract
Objective To discuss the results of the KETASER01 trial and the reasons for its failure, particularly in view of future studies. Methods KETASER01 is a multicenter, randomized, controlled, open‐label, sequentially designed, non‐profit Italian study that aimed to assess the efficacy of ketamine compared with conventional anesthetics in the treatment of refractory convulsive status epilepticus (RCSE) in children. Results During the 5‐year recruitment phase, a total of 76 RCSEs treated with third‐line therapy were observed in five of the 10 participating Centers; only 10 individuals (five for each study arm; five females, mean age 6.5 ± 6.3 years) were enrolled in the KETASER01 study. Two of the five patients (40%) in the experimental arm were successfully treated with ketamine and two of the five (40%) children in the control arm, where successfully treated with thiopental. In the remaining six (60%) enrolled patients, RCSE was not controlled by the randomized anesthetic(s). Significance The KETASER01 study was prematurely halted due to low eligibility of patients and no successful recruitment. No conclusions can be drawn regarding the objectives of the study. Here, we discuss the KETASER01 results and critically analyze the reasons for its failure in view of future trials.

Abstract
OBJECTIVE To study the long term effectiveness of intravenous immunoglobulin and plasmapheresis associated with prednisone and cyclophosphamide in Churg-Strauss syndrome. SUBJECTS and methods: We studied 18 subjects with new onset Churg-Strauss syndrome. All received the "standard" treatment based on prednisone (1 mg/kg/day for 1 month and then slowly tapered) and cyclophosphamide (2 mg/kg/day for 6 months in severe cases). In nine patients, synchronised cycles with plasmapheresis and intravenous immunoglobulin (2 g/kg) were repeated monthly for 6 months and every other month for a further three cycles. Clinical (disease activity monitored by Birmingham vasculitis activity score (BVAS) and damage index (modified Rankin score)) and functional (C reactive protein, blood eosinophil count, and electromyogram-electoneurogram) parameters were collected during treatment and the 3 year follow up period. RESULTS After 12 months, all patients in the treatment group and four (44%) in the control group were in remission. At the end of the 3 year follow up period, we documented significant differences in BVAS (p<0.01), global damage (p<0.02), modified Rankin score (p<0.04), and the daily maintenance prednisone dose (p<0.002) between the two groups. We found a tendency towards lower frequency of relapse and incidence of osteoporosis in the treatment group. CONCLUSION Complete clinical and functional recovery with a long term stable remission and a low incidence of side effects can be achieved by intravenous immunoglobulin associated with plasmapheresis in patients with Churg-Strauss syndrome.

Abstract
OBJECTIVE To determine whether some behavioural manifestations and poor motor performances in patients affected by rheumatoid arthritis (RA) are due to subclinical cognitive defects. METHODS We performed a psychometric assessment of 30 patients affected by RA exploring several cognitive domains such as memory, visual-spatial integration, motor planning, mental flexibility, relating performances with morphological and functional neuroimaging (MRI and SPECT). We also related the cognitive data with the Ritchie and Lee indexes and other clinical parameters. RESULTS We found an impairment in visual-spatial tasks in 71% of patients with a high correlation to activity and disease severity as expressed by the Ritchie and Lee indexes (p < 0.005; p < 0.01). Furthermore, we detected in 38% of patients some difficulties in mental flexibility related to the Lee Index (p < 0.05). These poor performances are related to hypoperfusion of the frontal and parietal lobes as detected by brain SPECT; this finding is more evident in patients with brain white matter alterations on MRI. CONCLUSIONS Our data allow us to hypothesize that manual dexterity could be due to a disconnection between subcortical white matter and parietal-frontal lobes because of microangiopathy; furthermore, a chronic reduction in sensorial stimuli by impaired joints could lead to produce an alteration in motor planning cognitive processes.

Abstract
OBJECTIVE To describe the treatment of polymyositis (PM) and dermatomyositis (DM) with prednisone (PRED) and cyclosporin A (CSA) alone or associated with intravenous immunoglobulin (IVIg) and plasmapheresis (PEX). METHODS Between 1992 and 1999 CSA and PRED were used to treat 20 patients with idiopathic myositis (12 with DM, eight with PM), diagnosed according to the Bohan and Peter criteria. In patients with refractory or relapsed disease, IVIg was added alone (seven cases) or synchronised with PEX (six cases). A standardised protocol was used to evaluate the patients, and assess disease activity and treatment response. RESULTS Despite a transient response to PRED and CSA in 16/20 cases, this combination did not induce full remission in 13/20 cases, which led to the IVIg trial with or without PEX. Patients receiving PRED and CSA plus IVIg had a significantly higher probability of maintaining complete remission at the end of the four year follow up period than those treated with PRED and CSA alone (p<0.001). No further benefit was added by the PEX. The presence of arthritis significantly correlated with a poorer response to treatment (p<0.05). Adverse effects were gingival hyperplasia (one patient) and transient renal dysfunction (one). CONCLUSIONS This open study suggests that combined treatment with PRED, CSA, and IVIg is useful in patients with myositis, even those with refractory or relapsed disease; no increase in the number or type of side effects is seen.

Abstract
This study compared iloprost and nifedipine to ascertain whether they could improve parameters of endothelial and platelet functions in the treatment of Raynaud's phenomenon secondary to systemic sclerosis. Thirteen patients affected by systemic sclerosis were treated with intravenous infusion of iloprost, and 7 patients were treated with oral nifedipine. Blood samples were taken at baseline and after 6 and 12 months of therapy to assess main serological indexes of endothelial damage, thrombin activation, fibrinolysis, as well as natural inhibitors of coagulation. After 12 months of therapy, the patients treated with iloprost had a significant decrease in thrombomodulin levels (p = 0.02) and a significant increase in tissue-plasminogen activator levels (p = 0.007), in comparison with the patients taking nifedipine (p = 0.007). Moreover, patients treated with nifedipine showed increased levels of thrombin-antithrombin complex after 12 months of therapy in comparison with baseline values (p = 0.03) and in comparison with the values of the patients treated with iloprost over the same period (p = 0.05). These preliminary results thus seem to indicate that iloprost plays an important, if at least partial, role in the protection and restoration of endothelial integrity in patients with systemic sclerosis.

Abstract
Previous data have indicated that organ-specific and non-organ-specific autoimmune diseases may occur in the same patient. We report here our study on the type and prevalence of endocrine autoimmune diseases in undifferentiated connective tissue disease (UCTD). A retrospective analysis revealed five out of 75 UCTD cases (6.6%) with cytology-verified autoimmune thyroiditis (associated with insulin-dependent diabetes mellitus in one case). Other UCTD patients had Graves' disease (one case), non-toxic multinodular goitre (two cases) and central hypothyroidism (one case). In a prospective study, thyroid function was evaluated in 15 consecutive UCTD patients with neither clinical nor laboratory signs of thyroid involvement. Basal and post-TRH stimulation TSH levels were significantly higher in UCTD patients than in healthy subjects.

Abstract
Recent changes in the Italian health care system are causing a complex redefinition of the traditional principles of nursing. Among the new principles that are being proposed, the implementation of a clinical practice based on the evidence generated by the medical research community appears to be prominent. However, objective time constraints in finding and evaluating the available information have often hampered the achievement of this highly desirable goal. In this perspective, exploitation of the intrinsic quickness of the internet-based information retrieval systems has the potential to effectively circumvent the problem. To provide nurses with a proper training in a timely search and evaluation of on-line data, we have designed and developed a guide to those websites providing clinical information. This guide consists of (1) reviews of existing websites, and (2) proposal of a standardized model for selection, evaluation, and description of existing and newly appearing websites. We believe that this guide might increase the capability of nurses to effectively exploit the medical and scientific information resources available on the net.

Abstract
OBJECTIVE To study those conditions with a proven or hypothesised immunologic pathogenesis and denominated under a working definition of undifferentiated connective tissue diseases (UCTD). METHODS A multicentre prospective study was organised involving 10 tertiary referral centers of internal medicine in Italy, with the aim of describing the natural history of UCTD and the prevalence of its different clinical and immunological manifestations. RESULTS After a five-year follow-up period, data on 165 patients were available for analysis. UCTDs occur mainly in females in their fourth decade of life. Articular and mucocutaneous features and Raynaud's phenomenon represent the most common findings. Nevertheless, we also detected a relatively high incidence of permanent major organ damage. Regarding the immunologic parameters, we documented some conflicting results in the correlation between serologic abnormalities and clinical features. In 10 patients UCTD evolved to a major disease, generally systemic lupus erythematosus or Sjögren's syndrome. CONCLUSION A low rate of evolution to a defined autoimmune disease, the limited use of steroid or immunosuppressive therapy, and a favourable course in the majority of cases are the main characteristics of patients with UCTDs.

Abstract
An international collaborative project for the evaluation of clinical competence at the end of the Medical School curriculum using the ECFMG-CSA (Educational Commission for Foreign Medical Graduates--Clinical Skills Assessment) prototype was started in Italy in April 1996. Faculty representatives from Italian Medical Schools and experts from the ECFMG in Philadelphia participated in the Project. The CSA consists of integrated clinical encounters with 10 standardized patients during which the examinee is asked to obtain a focused history, perform a relevant physical examination and communicate initial diagnoses and management plan to the Standardized Patient (SP). The SP then completes checklists that are scored by Faculty members. The project was concluded in Spring 1998 and a total of 173 new graduates were examined. The data elaborated by the primary site in Chieti University will be available in the Fall 1998 by the ECFMG in Philadelphia. This preliminary communication reports the opinions of the examinees on the ECFMG-CSA, contained in the questionnaires administered after the test. Most of the examinees considered this new methodology as a valid tool for the assessment of clinical competence, especially history-taking and interpersonal skills and stated that the SP simulations were realistic. The 72% of examinees indicated that the Medical School curriculum does not adequately prepare for the CSA examination. Lastly, 68% was in favour of including the SP in the Medical Licensing Examination.

Abstract
In this paper we tried to define the capillaroscopic pattern of anti phospholipid syndrome able to differentiate between the primary (PAPS) and the systemic lupus erythematosus-associated form (SLE-APS) and to be a predictive marker of thrombotic manifestations. Eight PAPS and five SLE-APS patients were studied. In each patient the evaluation was based on anti cardiolipin antibody levels, nailfold capillaroscopy, retinal fluorangiography and transcranial doppler sonography. Statistical analysis has been performed using chi 2 analysis. Morphological alterations of capillary loops, venular visibility and sludging of blood were often observed in both groups. While we found in higher prevalence a variability of capillary loop length in PAPS patients, the SLE-APL group significantly differed for the presence of microhaemorrhages (p < 0.001). When we evaluated the clinical history, a marked microcirculatory damage was related with the occurrence of thrombotic manifestations in the PAPS patients. Anti cardiolipin antibody levels, retinal fluorangiography and transcranial doppler sonography did not correlate with clinical history in either group. In conclusion, nailfold capillaroscopy can be usefully employed in the differentiation between primary and SLE-associated anti phospholipid syndrome, and it can help to identify the patients at higher risk of thrombotic disease.

Abstract
Connective tissue diseases (CTDs) are chronic multisystemic inflammatory disorders whose indicative signs or symptoms have a high sensitivity but poor specificity in predicting the evolution into a given CTD. We have analysed 84 consecutive patients initially diagnosed as having an early undifferentiated CTD (early UCTD) with the aim of verifying the evolution into one definite CTD and of evaluating the predictive value of clinical and laboratory parameters. During a 5-year study period, 33 patients developed signs of a full-blown CTD; the highest probability of evolution was in the first 48 months after the onset. Multivariate analysis allowed us to select those variables correlating with evolution into a particular CTD, such as sclerodactyly and oesophageal dysfunction for systemic sclerosis, xerostomia and anti-nuclear antibodies (SS-A pattern) for Sjögren's syndrome, and fever and anti-DNA antibodies for systemic lupus erythematosus. Furthermore, we assessed the prevalence of various clinical and laboratory manifestations, complications and prognosis of those patients diagnosed after a 5-year disease duration period as having a UCTD. In our series, major organs such as the kidney or heart seem to be spared, whereas we detected a relatively high prevalence of endocrine disease of autoimmune origin.

Abstract
Rheumatoid arthritis (RA) is a chronic multisystemic disease affecting mainly the joints and characterised by a poor prognosis. In a four month open study we evaluated the efficacy and tolerability of a combination therapy in 14 patients with active and refractory RA (non responsive to MTX or CsA monotherapy). After three pulses of methyl-prednisolone (125 mg/die i.v. for 3 days), at day the 4 patients received methotrexate (MTX 15/mg/week p.os) and cyclosporine (CsA 3 mg/kg/day p.os). At the end of treatment period, patients had a statistically significant improvement in the tender-joint count (Ritchie Index) in the swollen-joint count and in the pain as recorded on a 100-mm visual-analogue scale. Following the criteria of the American College of Rheumatology for response to treatment in RA, 6 patients (60%) met these criteria, whereas 2 had a worsening. We could not detect any clear difference in serological parameters (ESR, CRP and Hb levels) between the beginning and the end of the therapy. A significant difference in the score of edema/joint effusion was documented at the RM analysis. Side-effects were not substantially increased as compared to MTX or CsA in single therapy. Combination therapy with CsA and MTX seems to be a safe and effective treatment for patients with active and refractory RA.

Abstract
In this paper we considered different models concerning the clinical expression of neuropsychiatric involvement in course of systemic lupus erythematosus (SLE). These models describe pathological conditions as multifocal cerebropathy, transverse myelitis, peripheral neuropathy and panic attacks. We have chosen these cases as clinical example of different pathogenic mechanisms responsible of CNS-lupus, as hypercoagulation due to antiphospholipid syndrome, immune-complex vasculitis, complement-mediated autoantibody damage and antibody-induced cytotoxicity. The prevalence of neuropsychiatric manifestations in 122 SLE patients is also reported. Finally, the paper reports some guidelines about diagnostic and therapeutic behaviour in course of CNS-lupus.

Abstract
In absence of thrombocytosis, periodic bloodlettings represent the elective therapy of polycythemia vera. In the present study we tested if neocytoapheresis, a method able to remove large quantities of younger, and then bigger red cells could represent an alternative therapeutic choice in these patients. We found that the employment of neocytoapheresis produced a remarkable delay in the time of procedures with a mean interval of 100 +/- 55 days. The mean value of hematocrit before neocytopheresis is resulted statistically different in comparison with the hematocrit after the procedure (p = 0.0001). The reticulocyte count is resulted higher in apheresis product in comparison with the blood control measured before procedure (p = 0.0001). In the same way, the mean corpuscular volume in the collection bags was higher than the volume measured before neocytoapheresis (p = 0.0095). We did not find any variation about the mean values of white blood cells and platelets before and after neocytoapheresis in the patients examined. These preliminary data seem to underline a better withdrawal of big size cells by this technique suggesting the efficacy of neocytoapheresis in the treatment of polycythemia vera.

Abstract
OBJECTIVE Based on serological and molecular evidence of hepatitis C virus (HCV) infection in a significant proportion of patients with mixed cryoglobulinemia (MC), a direct association between HCV and MC has been suggested. The goal of the present study was to investigate the role played by HCV and by the immune response to the virus in the pathogenesis of mixed cryoglobulinemia. METHODS A competitive reverse transcription polymerase chain reaction was employed to evaluate the concentrations of specific HCV RNA sequences in different clinical specimens (plasma, sera, cryoprecipitates, bone marrow and peripheral blood cells). Using recombinant and synthetic peptides covering the HCV core, envelope 1 (E1) and nonstructural regions 4 (NS4) and 5 (NS5), the humoral immune response in a group of MC patients was assessed with an enzyme-linked immunosorbent assay. Natural killer (NK) cell activity was estimated using a 4 hr 51 Cr release assay. RESULTS Quantitation of the RNA molecules in the biological samples confirmed an increased virion concentration in cryoprecipitates from 13/15 patients with mixed cryoglobulinemia. Analysis of the humoral immune response against the synthetic peptides suggested a distinct response to HCV antigens in MC patients when compared to patients with HCV infection but without serological evidence of cryoglobulinemia. Unstimulated NK cell functioning was below the normal range in all patients tested. However, peripheral blood mononuclear cells showed no enhancement of NK activity by the interferon inducer polyinosinic acid:polycytidilic acid. Enhancement by interferon-alpha was normal, suggesting an impairment in interferon production. CONCLUSION The quantitative data are in line with the hypothesis of a direct or indirect role of HCV in mixed cryoglobulinemia. The abnormal immune response could be involved in the onset and persistence of HCV infection, and possibly in the appearance of cryoglobulinemia.

Abstract
PURPOSE The purpose of this study was to assess whether granulocytopenia observed in 3 of 38 patients with essential mixed cryoglobulinemia who were treated with low-dose interferon was due to the underlying disease or to synergistic toxicity of interferon with other drugs. PATIENTS AND METHODS Adverse effects of interferon therapy were monitored in 38 patients affected with type II essential mixed cryoglobulinemia. Patients were treated with 3 million units (MU), daily or on alternate days, of recombinant interferon-alpha 2a (35 patients) or with natural interferon-beta (3 patients). The duration of treatment ranged between 6 and 15 months; the total duration of follow-up, including after therapy, ranged between 8 and 93 months. RESULTS None of 35 patients treated with interferon alone developed significant hematologic alterations. In addition, none of 7 patients treated with angiotensin-converting enzyme (ACE) inhibitors alone showed hematologic toxicity. Three patients who were treated with a combination of interferon and ACE inhibitors developed severe granulocytopenia a few days after starting treatment. Granulocytopenia subsided within 1 to 2 weeks after suspending therapy. Resumption of treatment with this drug combination produced a granulocytopenia relapse in 1 patient. In these 3 patients, interferon treatment alone, or ACE inhibitor monotherapy, was not followed by granulocytopenia. CONCLUSION Although severe hematologic toxicity rarely develops in patients treated with low-dose interferon, granulocytopenia occurred in all 3 of our patients with mixed cryoglobulinemia who were treated with a combination of low-dose interferon-alpha 2a and ACE inhibitors. Neither drug alone was toxic in any of our cryoglobulinemic patients, indicating a high risk of severe hematologic toxicity for this drug combination, at least in patients with this disease. Physicians should be aware of this danger when using interferon treatment in patients with this, or possibly other, disorder(s) that also require antihypertensive therapy.

Abstract
OBJECTIVES Because sudden death due to complete atrioventricular (AV) block or ventricular arrhythmias is the most dramatic event in myotonic dystrophy, we assessed the relation of cardiac disease to cytosine-thymine-guanine (CTG) triplet mutation in adults affected with myotonic dystrophy. BACKGROUND The myotonic dystrophy mutation, identified as an unstable deoxyribonucleic acid (DNA) sequence (CTG) prone to increase the number of trinucleotide repeats, produces clinical manifestations of the disease in skeletal muscle, the heart and many organ systems. METHODS Forty-two adult patients underwent electrocardiography and echocardiography; in addition, signal-averaging electrocardiography was performed in 22, and 24-h Holter monitoring was recorded in 32. The diagnosis was established by neurologic examination, electromyography, muscle biopsy and DNA analysis. The patients were then classified into three subgroups on the basis of the number of CTG trinucleotide repeat expansions: E1 = 18 patients with 0 to 500 CTG repeats; E2 = 12 patients with up to 1,000 repeats; E3 + E4 = 10 patients with up to 1,500 repeats and 2 patients with > 1,500 repeats. RESULTS The incidence of normal electrocardiographic (ECG) results was found to be significantly different in the three subgroups (55%, 50%, 17% in E1, E2, E3, + E4, respectively, p = 0.04), with the highest values in the group with fewer repeat expansions. The incidence of complete left bundle branch block was also significantly different among the groups (5% in E1, 0% in E2, 42% in E3 + E4 p = 0.01) and was directly correlated with the size of the expansion. A time-domain analysis of the signal-averaged ECG obtained in 12 patients in E1, 4 in E2, 5 in E3 and 1 in E4 showed that abnormal ventricular late potentials were directly correlated with CTG expansion (33% in E1, 75% in E2, 83% in E3 + E4, p = 0.05). Moreover, the incidence of ventricular couplets or triplets showed a positive correlation with size of CTG expansion (0 in E1, 0 in E2, 29% in E3 + E4, chi square 0.02). CONCLUSIONS Our findings suggest that the involvement of specialized cardiac tissue, accounting for severe AV and intraventricular conduction defects, is related to CTG repeat length. In addition, the presence of abnormal late potentials directly correlates to CTG expansion. Abnormal late potentials, caused by slowed and fragmented conduction through damaged areas of myocardium, represent a substrate for malignant reentrant ventricular arrhythmias. In the future, therefore, molecular analysis of DNA should identify patients with cardiac disease at high risk for development of AV block or lethal ventricular arrhythmias.

Abstract
OBJECTIVE Since fish oils seem to play a potential role in the treatment of inflammatory disorders by inhibiting arachidonic acid metabolism, the purpose of this study was to determine their therapeutic efficacy in mixed cryoglobulinemia (MC), an inflammatory condition caused by the deposition of immune complexes in vessel walls. METHODS In an 8-week double-blind randomized trial, ten MC patients received a daily dietary supplement of 3 gm of eicosapentaenoic acid (EPA) and 2 gm of docosahexenoic acid (DHA), while 10 other MC patients received placebo (olive oil). The severity of purpura, arthralgias, paresthesias, asthenia and Raynaud's phenomenon were monitored daily, and serological assays were performed at the beginning of the study, at the end of the treatment period, and after 4 weeks of wash-out. RESULTS No significant differences were found between the two groups with regard to the clinical symptoms, although the percentage of patients who reported a clinical improvement was higher in the group treated with fish oils. As for the serological parameters, no variation was found in the placebo group, while in the group receiving fish oils a significant decrease in cryocrit and rheumatoid factor levels was observed, which in the case of rheumatoid factor persisted at the end of the wash-out period. CONCLUSIONS Under the experimental conditions employed in this study, we could not demonstrate a significant improvement in clinical symptoms in patients with mixed cryoglobulinemia treated with fish oils. However, since our results indicated some improvement in the serological parameters potentially involved in the pathogenesis of the disorder, further studies are warranted to establish the optimal dose and duration of fish oil supplementation in the treatment of MC.

Abstract
Endomyocardial biopsy is still considered the only reliable method for diagnosing acute rejection. However, because of its invasive nature, this procedure cannot be performed on a daily basis. Therefore, for the noninvasive monitoring of transplanted patients, we tested the sensitivity of serum levels of basement membrane antigens, type IV collagen fragment NC1 and laminin fragment P1 (LP1), of antibodies against laminin and type IV collagen, and of soluble interleukin 2 receptor (sIL2R). In 17 patients who underwent heart transplantation no correlation was found between the degree of rejection and the levels of antibodies to type IV collagen and laminin. Serum laminin P1 and sIL2-R values were found increased in all the study groups even in absence of rejection; however, sIL2R levels were higher in patients with more severe rejection. NC1 levels were found significantly higher in patients with mild or moderate rejection than in those with no rejection or in controls. These preliminary data suggest a possible predictive role of basement membrane antigens in cardiac rejection, but further studies in a larger group of transplanted patients are needed.

Abstract
We have investigated the distribution of TGF beta using antibodies specific for its intracellular and extracellular forms in full-thickness biopsies of patients with SSc, primary Raynaud's phenomenon (PRP), systemic lupus erythematosus (SLE), and from normal subjects. Nine of 11 SSc biopsies demonstrated intracellular TGF beta in endothelial cells while only 6 exhibited extracellular TGF beta. Endothelial cells in skin biopsies of all PRP patients displayed both intracellular and extracellular TGF beta. All other control biopsies were negative. In patients with PRP, some positively staining fibroblasts were found scattered throughout the dermis. Lastly, extracellular TGF beta was localized in the papillary dermis of PRP and SSc biopsies and in all the dermal layers of SLE patients. No significant staining of TGF beta was observed in the endothelial cells, fibroblasts, or in the extracellular matrix of the majority of biopsies from normal subjects. These data suggest that TGF beta may be one of the cytokines involved in the early stages of pathogenesis of SSc, and that endothelial cells in SSc and PRP may be a source and/or a target of TGF beta.

Abstract
The increase of survival in patients with Hodgkin's disease (HD) has made appear the problem of secondary neoplasms, included acute leukemias. The authors evaluate the incidence of acute leukemias in 205 HD with a follow-up more than 12 months (mean 92 months). With regard to these latter, 18 (8.7%) were treated with radiotherapy alone, 69 (33.6%) with chemotherapy alone and 118 (57.5%) with a combination of radiotherapy and chemotherapy. Chemotherapy consisted of 2-12 courses of MOPP alone or in combination with ABVD. The relative risk of acute leukemias is 96.7 (CI 95%: 44.2-183.6): nine cases against an expectancy of 0.093. The risk changes during five-years periods, but not significantly, and it not declines after ten years from the diagnosis. Only the alkylating chemotherapy seems to be important to favour the onset of acute leukemias. Among the patients who received a number of courses of MOPP less or equal than 6 (177), seven developed an acute leukemia (relative risk 85.3; CI 95%: 34.3-175.9); among those who received more than 6 (9), two developed an acute leukemia (relative risk 333.3; CI 95%: 40.3-1204.1). Neither the addition of radiotherapy nor the stage nor the splenectomy nor the histotype favour the onset of acute leukemia.

Abstract
The Myelo-Dysplastic Syndromes are a heterogeneous group of diseases which includes patients with different prognosis. There is no agreement about the management and the therapeutic strategy must be based on many individual parameters, particularly the age of the patients and their performance status. The therapeutic options range from no cytotoxic therapy for low-risk patients up to more aggressive treatment for high-risk patients, with disappointing results except for the very few cases eligible for allogenic bone marrow transplantation. The leukaemic cell can be induced to differentiate, so losing its self-maintenance potential; different drugs such as Interferon, vitamin D3, retinoids and arabinosyl-cytosine (low doses) have shown a differentiating action on myeloid blasts in "vitro". We summarize the general strategy in the treatment of myelo-dysplastic syndromes based on literature data, and on our results about the efficacy and tolerance of a combination of the above mentioned differentiating drugs, in a group of 27 elderly patients affected by myelodysplastic syndrome with poor prognosis. We obtained 14 objective responses (52%), and the median overall survival of these patients have been compared with that of 25 patients with severe myelodysplastic syndrome treated with a conventional regimen. In the 27 patients receiving the differentiating combination the median survival was found to be 14.7 months, versus 8.4 months for the control group. The results obtained are encouraging about the tolerance and the efficacy of this combination in elderly patients with a poor MDS prognosis. Further randomized studies are necessary to establish whether this treatment can really improve the survival in this group of patients.

Abstract
Soluble interleukin 2 receptor (sIL2R) may be used as an index of immune perturbation. We report on the correlation between the serum levels of sIL2R, as assessed with a sandwich-ELISA, and disease activity in 61 patients with Systemic Lupus Erythematosus (SLE) and in 15 with systemic idiopathic vasculitis (SIV). The mean levels of sIL2R in SLE and SIV patients were significantly higher than in healthy controls and higher values were detected in patients with active disease or severe organ involvement or infection. We also studied patients with clinically silent SLE, characterized by the presence of several immunologic abnormalities. The sIL2R mean level in this group did not differ from that of quiescent SLE patients, suggesting that immunologic alterations are present even in inactive SLE. Finally, the sIL2R assay showed higher sensitivity and specificity than most of the common immunologic parameters.

Abstract
Immune reactivity to the 65-kDa mycobacterial heat shock protein (hsp65) has been associated with arthritis in rats and humans. In this report we evaluated patients with juvenile rheumatoid arthritis for such immunity. A high proportion of affected children showed both antibody and T lymphocyte responses to hsp65 and to two related peptides: the nonapeptide 180-188 sequence of hsp65 and a partially homologous peptide of the cartilage proteoglycan link protein. The titer of circulating antibodies was generally higher in patients with clinically active disease. In contrast to the juvenile rheumatoid arthritis patients, patients with adult rheumatoid arthritis tended to have lower responses of their peripheral blood T lymphocytes to the whole hsp65 molecule. Moreover, the adult rheumatoid arthritis patients did not respond to the peptides. Thus, there appear to be immunological differences between juvenile and adult forms of rheumatoid arthritis related to hsp65 reactivity.

Abstract
It has been reported that immunity to the 65 kDa heat shock protein of Mycobacterium tuberculosis (MT-hsp65) not only accompanies rheumatoid arthritis (RA), but may also be characteristic of chronic inflammation. We now report serum antibodies to MT-hsp65 in 47% of systemic sclerosis (SSc), 38% of primary Raynaud's phenomenon (PRP) and 5% of systemic lupus erythematosus (SLE). Antibody levels were higher in patients with active or progressive SSc and correlated with the degree of skin fibrosis. Thus, immunity to MT-hsp65 appears in SSc and is not limited to RA. However, it does show some degree of specificity beyond chronic inflammation: PRP patients have a higher reactivity than do SLE patients.

Abstract
Systemic sclerosis (scleroderma) is characterized by excessive fibroblastic activity taking place through mechanisms largely unknown. It has been speculated that soluble factors, collectively categorized as lymphokines or monokines, and released by inflammatory or other differentiated cells, may modulate fibroblast multiple functions including migration, chemotaxis and protein synthesis. Vascular endothelium itself, which is deeply injured in systemic sclerosis, is acting as a target for the action of cytokines and is an important producer of polypeptide mediators that contribute to the inflammatory reaction and to the establishment of fibrosis. Thus, interactions through soluble mediators between fibroblasts, endothelial cells and immunocompetent cells appear crucial for the development of systemic sclerosis lesions. The aim of the present study is to evaluate the available information on the role of cytokines and to discuss their potential influence in the pathogenesis of systemic sclerosis.

Abstract
Sera from 224 patients with systemic sclerosis (scleroderma) were analyzed for circulating antibodies against an antigenic determinant characterized by two molecules of galactose in alpha 1-3 linkage. About 45% of the patients were found to have values above the normal range. The mean antibody level was significantly higher than that found in normal subjects (p less than 0.001) or in patients with primary Raynaud's phenomenon who were included as controls. The mean level of anti-Gal antibodies correlated with the degree of skin and internal organ involvement, as well as with the presence of progression or inflammation. Furthermore, when patients with early onset disease were analyzed, high levels of anti-Gal antibodies were present in the subgroups characterized by evidence of progression or inflammation, whereas patients with stable disease did not differ from the controls. We conclude that humoral immunity against Gal alpha 1-3 Gal is an early feature of scleroderma, may be important for its pathogenesis, and may provide a more sensitive tool to detect disease activity.

Abstract
Our aim was to assess whether the amount of complement C3b/C4b receptors (CR1) on erythrocytes shows a correlation to disease activity in various connective tissue diseases such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA) and essential mixed cryoglobulinemia (EMC). Using an anti-CR1 monoclonal antibody, 26 patients with SLE, 34 with RA and 22 patients with EMC were investigated for erythrocyte CR1 expression. The control group consisted of 30 healthy individuals. The mean number of CR1/erythrocyte in the control group was 568 +/- 197 (range 174-1060), significantly higher than studied (EMC:379 +/- 248; p = 0.0005;SLE 147 +/- 56, p less than 0.0001; RA 298 +/- 177, p less than 0.0001). In patients with RA and in SLE, but not in patients with EMC, the number of CR1 numbers and anticardiolipin antibody (aCl) titers (r2 = 0.493; p = 0.034). A statistically significant correlation between CR1 numbers and CH50 values was found in patients with SLE, while in 3 patients with RA 4 months of therapy with cyclosporine A led to a further 30% reduction in CR1 number. Our conclusions are that (a) the decreased expression of erythrocyte CR1 is apparently a common feature of patients with various connective tissue diseases; (b) several acquired factors such as disease activity, complement activation, aCl and drugs may contribute to the loss of CR1 from erythrocytes; (c) in patients with RA and SLE, but not in patients with EMC, CR1 enumeration on erythrocytes may serve as a variable for clinical monitoring.

Abstract
Interleukin-2 (IL-2), soluble interleukin-2 receptor (IL-2R) and tumor necrosis factor (TNF) have been measured in sera from 47 patients affected by classic rheumatoid arthritis (RA) using an enzyme-linked immunosorbent assay. The patients were divided into 4 groups as follows: group A, 18 patients with inactive disease; group B, 19 patients with active disease under treatment with non-steroidal antiinflammatory drugs (NSAID) and second-line drugs; group C, 5 patients with active disease under treatment with NSAID and cyclosporine A (CSA) for at least 4 months; group D, 5 patients in the same condition as patients of group C, but treated with azathioprine (AZA) instead of CSA. IL-2 was undetectable in all patients except two, both characterized by active disease. Soluble IL-2R levels were above the upper limit of the normal range in most of the patients studied, but the mean value ( +/- 1 SD) was significantly higher in patients of group B (1,288 +/- 421 U/ml) than in patients of group A (686 +/- 205 U/ml) and group C (842 +/- 414 U/ml). In two patients affected by active RA treated with pulse methylprednisolone therapy (1 g/day for 3 alternate days) the values of soluble IL-2R dropped from 948 to 662 U/ml and from 660 to 518 U/ml, respectively. No statistically significant correlation was observed between the serum level of IL-2R and the RF titre or percentage of C1q-binding activity, respectively. TNF was found within the normal range in all patients except one, who was characterized by active arthritis, high number of rheumatoid skin nodules and extremely high RF titre.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The aim of the present work was to evaluate the action of cyclosporin (CsA) both in vivo and in vitro on the active sodium transport across the erythrocyte membrane of rheumatoid arthritis (RA) patients. The in vivo study was performed on 20 patients affected by refractory RA and treated with CsA (5 mg/kg/die) or with azathioprine (2 mg/kg/die) before and after 7 days' therapy. The control group was formed of 25 healthy subjects. RA patients before treatment showed increased intra-erythrocyte Na+ concentration and decreased Na+, K+ ATPase activity in comparison with normal subjects. A rise in the activity of the sodium pump and a reduction in the intra-erythrocyte Na+ concentration were observed after cyclosporin treatment, but not after azathioprine. The in vitro study was performed on intact RBCs and on erythrocyte membranes from 15 healthy subjects and from 12 patients affected by classical RA, in the presence or absence of CsA (0.5-1-2 micrograms/ml). CsA (0.5 micrograms/ml) increased the Na+, K+ ATPase activity in intact RBCs and in erythrocyte membranes from both groups of subjects. Intracellular Na+ was decreased only in erythrocytes from RA patients after addition of 0.5 micrograms/ml CsA. A direct action of CsA on the membrane hydrophobic environment of the Na+, K+ ATPase is hypothesized on the basis of the present results.

Abstract
The case of a 21-year-old patient operated on as an emergency for traumatic rupture of the suprahepatic inferior vena cava (IVC) and hepatic vein (HVs) is presented. Since anatomic reconstruction of the ruptured vessels was considered unfeasible, a direct anastomosis was instituted between the right atrium and the liver capsule around the disrupted IVC and HVs, using extracorporeal circulation, deep hypothermia and circulatory arrest. Hemorrhage was easily controlled and the patient survived. As far as we know, this operation, originally developed for the treatment of the Budd-Chiari syndrome, has never been used before as a life saving procedure under the circumstances described.

Abstract
Three patients with life-threatening manifestations of systemic lupus erythematosus (SLE), unresponsive to conventional high-dose corticosteroid and/or immunosuppressive therapy were treated with intravenous polyspecific IgG (IVIG). Following IVIG infusion, lupus encephalitis in the first patient quickly resolved and the impressive improvement of the clinical status was associated with a transient increase in C1q-binding activity. The daily infusion of IgG had to be suspended after three days in the second patient with encephalitis and nephritis, because the renal function rapidly deteriorated; subsequently, six plasma exchanges led to an almost complete recovery. Finally, leukocyte and platelet counts increased and remained within normal range following IgG therapy in the third patient having SLE-associated leuko- and thrombocytopenia. In all three patients a decrease in anti-DNA antibody levels and an increase in total complement hemolytic activity were detected after therapy.

Abstract
When compared with 40 normal controls, 46 patients with essential cryoglobulinemia had higher serum concentrations of a basement membrane antigen, laminin fragment P1 (LP1). Serum LP1 values were more pronounced in patients with visceral involvement, compared with those with skin vasculitis only. Asymptomatic patients or those with arthralgia usually had normal values. Increased disease activity was associated with a significant increase in LP1 (P less than 0.01). For evaluation of disease activity, determination of serum LP1 was a more sensitive measure than any complement factor assay.

Abstract
Antibodies against type IV collagen were detected in the sera of 21% of patients with primary Raynaud's phenomenon (PRP) and 68% of patients with systemic sclerosis. Sera from 25% of the PRP patients and 48% of systemic sclerosis patients displayed antibodies to laminin. Eighty percent of the patients with PRP and antibodies to basement membrane antigens developed additional serologic or clinical manifestations, whereas only 16% of patients with PRP and no anti-basement membrane antibodies developed such manifestations.

Abstract
An abnormality of sodium handling has been suggested as one of the mechanisms responsible for the development of pregnancy-induced hypertension. We analysed the plasma and urinary concentrations, and the intraerythrocyte activities of Na and K, and the RBC membrane Na+/K+-ATPase activity of 77 hypertensive and 133 normal pregnant women. Umbilical cord blood of infants from 21 hypertensive and 28 control women was studied. The Na+/K+-ATPase activity was determined by measuring the inorganic phosphate released by incubation in a reaction medium in the presence and absence of K ions or ouabain. The intra-erythrocyte sodium and potassium activities were measured by ion-selective electrode analysis of the haemolysates, after washing the RBCs in 110 mmol/l MgCl2. We found a significant increase in intracellular sodium and a reduction in Na+/K+-ATPase activity in the hypertensive women in comparison with the control subjects during pregnancy. No difference was observed in early puerperium. Cord blood from infants of pregnancy-induced hypertensive women showed an increase in intracellular Na+ activity and a decrease in the erythrocyte membrane Na+/K+-ATPase activity in comparison with cord blood samples from control subjects. The observed abnormalities in the plasma membrane sodium transport may play a major role in the pathophysiology of pregnancy-induced hypertension.

Abstract
Imidazole salicylate (750 mg t.i.d.) was compared with ibuprofen (400 mg t.i.d.) in a 30-day multicenter double-blind clinical trial in patients with osteoarthrosis. Both drugs were effective in relieving joint pain and in reducing the duration of morning stiffness. A statistically significant reduction of the severity of these symptoms was observed already one week after the start of treatment, lasting until the end of the study. No significant differences in efficacy were demonstrated between the two drugs throughout the trial. The systemic tolerability, assessed by changes in tests of hematological, liver and kidney function, was excellent with both treatments. The incidence of side effects (mostly gastrointestinal complaints) was fairly low in both groups, and lower in the group treated with imidazole salicylate.

Abstract
To gain insight into the pathogenic mechanisms of immune complex-mediated vasculitis, clinically normal skin specimens from the forearms of 12 patients with essential mixed cryoglobulinemia were investigated by light microscopy, immunofluorescence microscopy, and electron microscopy. Basement membrane alterations were documented in 9 patients. Eleven patients had deposits in vessel walls, but only in 1 was there evidence of inflammation. The same immunoglobulins of the cryoproteins could be demonstrated in the tissue deposits by immunofluorescence analysis and by immunoelectron microscopy. These findings suggest that, in essential mixed cryoglobulinemia, immune reactants in dermal vessels of normal skin are more common than is evidenced by clinical examination. Moreover, it seems that cryoglobulins, as such, are not sufficient to trigger an inflammatory process: Additional local or plasma factors are required. Deposits were absent in 7 patients with cryoglobulinemia that was associated with a primary disorder. This could be ascribed to the lower cryocrit levels documented in this group of patients, or to the shorter duration of their disease.
