Abstract
Secondary lymphoedema of the leg can result in disruption of lymphatic vessels following lymph node surgery. Evidence supports the use of complex decongestive physiotherapy (CDP) in such cases, despite the possibility of tumour recurrence due to this therapy in cancer patients. We present the case of a 52-year-old woman who developed in-transit metastases and systemic evaluable disease one month after starting CDP for secondary lymphoedema of the leg.

Abstract
Flow cytometric analysis is a technique which allows not only phenotypical characterization of cellular subsets but also allows quantitation of cellular antigens. In this paper we summarize the Molecules of Equivalent Soluble Fluorochromes (MESF) units and the Antibody Binding Capacity (ABC) methods.

Abstract
The "Euro-Lupus Cohort" is composed by 1,000 patients with systemic lupus erythematosus (SLE) that have been followed prospectively since 1991. These patients have been gathered by a European consortium - the "Euro-Lupus Project Group". This consortium was originated as part of the network promoted by the "European Working Party on SLE", a working group created in 1990 in order to promote research in Europe on the different problems related to this disease. The "Euro-Lupus Cohort" provides an updated information on the SLE morbidity and mortality characteristics in the present decade as well as defines several clinical and immunological prognostic factors.

Abstract
OBJECTIVE In B27 transgenic rats, susceptibility to the development of a spondyloarthropathy-like disease has been shown to correlate with the level of B27 transgene expression on lymphoid cells. The aim of this work was to study HLA-B27 molecule expression in peripheral blood mononuclear cells (PBMCs) from patients with ankylosing spondylitis (AS) and from normal controls (NC). METHODS Twenty B27(+) AS patients and 16 B27(+) NC were studied. HLA-B27 whole molecules and free heavy chains (HCs) and total HLA class I molecules were evaluated at the surface of PBMCs by immunofluorescence and flow cytometry. B27 subtypes were defined with the PCR-SSP (polymerase chain reaction-sequence-specific primer) technique. Cellular activation was evaluated by the expression of CD69, CD25 molecules and interferon gamma (IFN-gamma) production. RESULTS B27 expression was 55,536.3+/-18,961.0 MESF (molecules of equivalent soluble fluorochromes) units in AS and 25,936.0+/-12,117.5 MESF in NC (P=0.00009), total HLA class I expression was 448,840.2+/-136,293.8 MESF in AS and 533,494.4+/-232,931.1 MESF in NC (not significant), HC expression was 10,593.4+/-6,396.1 MESF in AS and 14,843.0+/-7,544.2 MESF in NC (not significant). The higher B27 expression in the SA group was not due to higher cell activation as it was not correlated with CD69 and CD25 expression in PBMCs or with the level of IFN-gamma. HLA-B27 expression did not correlate with indexes of disease status [Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI) and Bath Ankylosing Spondylitis Metrology Index (BASMI)]. CONCLUSIONS We found greater expression of HLA-B27 molecules in patients with AS than in healthy subjects. This phenomenon was not accompanied by general up-regulation of HLA class I molecules or by greater expression of classical T-cell activation markers. On this basis we propose that the higher expression of the HLA-B27 molecules is a further predisposing factor for the development of AS.

Abstract
We report the case of a 30-year-old caucasian woman affected by SLE who developed neurological symptoms (prosopagnosia and visual-spatial agnosia) after nine years of disease. Brain MRI showed no abnormalities while a brain SPECT scan showed diffuse uptake defects and hypoperfusion areas in the right and left frontal-parietal regions. At that time the patient was on hydroxychloroquine (400 mg/day) and oral prednisolone (0.5 mg/kg/day) as maintenance therapy. One year later the patient showed worsening of Raynaud's phenomenon with digital dystrophic lesions and was therefore treated with an intravenous infusion of Iloprost (1.5 ng/kg/min per 6h/day for 10 days consecutively), while baseline treatment remained unchanged. One month later the patient showed a dramatic improvement in her cognitive function and subsequent SPECT scans showed the gradual disappearance of perfusion abnormalities. This first report of Iloprost treatment in CNS lupus suggests the potential therapeutic usefulness of this drug in patients with SLE and functional CNS involvement.

Abstract
Ankylosing Spondylitis (AS) is characterised by the strongest association with an HLA antigen ever described for any disease. It represents therefore the ideal model for the understanding of the link between immune-mediated diseases and the HLA system. The role of HLA-B27 in the pathogenesis of AS will be discussed focusing on the recently described higher expression of these molecules in patients with AS compared with healthy controls.

Abstract
Chloroquine (CQ) resistance in Plasmodium falciparum contributes to growing malaria-attributable morbidity and mortality in sub-Saharan Africa. However, the extent and degree of such resistance vary considerably between endemic areas. Data on CQ resistance in northern Ghana are almost entirely lacking. The therapeutic efficacy of CQ in uncomplicated malaria was therefore assessed, in a standard, 14-day protocol, in 225 children aged <5 years in Tamale, in the Northern region of Ghana. Early treatment failure (ETF) was observed in 11% of the children and late treatment failure in 18%. High initial parasite density and young age were independent predictors for ETF. Resistant parasitological responses (RI-RIII) were seen in 57% of the cases that could be classified. More than half of these responses occurred in children fulfilling the criteria for adequate clinical response (ACR), indicating a considerable lack of agreement between parasitological and clinical outcome. During the follow-up period, haemoglobin levels increased by approximately 1g/dl not only in patients with ACR but also in those who experienced clinical failure more than 1 week post-treatment. As CQ-treatment failure occurred in >25% of the children and more than half of the parasitological responses indicated resistance, current recommendations for the treatment of uncomplicated malaria in young children in northern Ghana have to be reconsidered.

Abstract
To our knowledge, only three cases of remitting symmetrical pitting oedema in systemic lupus erythematosus have been reported so far. This is the first report of two patients with asymmetrical pitting oedema and systemic lupus erythematosus. The first patient presented two consecutive episodes of unilateral oedema. The first episode involved the distal part of the right lower extremity and remitted spontaneously while the second involved the volar region of the left wrist and distal half of the forearm and promptly responded to steroids. Magnetic resonance imaging of the left wrist and forearm showed tenosynovitis of the flexor tendons and subcutaneous oedema. The second patient instead developed a single episode of pitting oedema of the distal part of the right lower extremity that resolved spontaneously. Magnetic resonance imaging of the right ankle and foot showed subcutaneous oedema without involvement of the tendon sheaths or osteoarticular and ligamental structures. These two cases suggest that pitting oedema in systemic lupus erythematosus may occasionally be asymmetric and associated or not with tenosynovitis.

Abstract
The aim of this study was to evaluate morphological and functional abnormalities by cerebral imaging in a series of systemic lupus erythematosus (SLE) patients with and without overt central nervous system (CNS) manifestations, and to detect possible relationships with clinical parameters and a large panel of autoantibodies, including those reactive against neurotypic and gliotypic antigens. 68 patients with SLE were investigated in a cross-sectional study which included clinical evaluation of symptoms, cerebral magnetic resonance imaging (MRI) and brain single photon emission tomography (SPECT) analysis, electroencephalography (EEG), and serological tests for antibodies directed against nuclear, cytoplasmic neuronal and glial cell-related antigens. The results of this study showed: (1) a significant positive association of (a) anti-glial fibrillary acidic protein (GFAP) serum antibodies with neuropsychiatric (NP) manifestations and (b) anti-serin proteinase 3 (anti-PR3/c-ANCA) serum antibodies with pathological cerebral SPECT; (2) the presence of significantly higher values of (a) SLICC organ damage index in patients with abnormal MRI and (b) SLAM activity index in patients with abnormal SPECT; and (3) the association of (a) abnormal MRI with nonactive NP manifestations and (b) combined abnormality of brain SPECT and MRI with the occurrence of overall overt NP manifestations and with those of the organic/major type. Neuropsychiatric manifestations, namely those of the organic/major type, appeared to be significantly associated to the presence of a serum antibody against GFAP, a gliotypic antigen. There was also evidence of an association between SPECT abnormality and the presence of anti-PR3 (c-ANCA). Furthermore, brain imaging by MRI and SPECT applied to SLE patients appears to express CNS involvement significantly related to specific categories of NP manifestations. The abnormalities detected by the two tests seem to be preferentially associated with different activity phases of the NP disorder or of the lupus disease.

Abstract
OBJECTIVE We investigated the distribution of MICA triplet repeat polymorphism in a random population and in patients with seronegative spondyloarthritis from Sardinia compared to continental Italy. METHODS We analyzed the distribution of MICA triplet repeat polymorphism in HLA-B*2709 [not associated with ankylosing spondylitis (AS)] and B*2705 (associated with AS) haplotypes, to verify whether the strong association of MICA-A4 with HLA-B27 reported in other populations is maintained in Sardinia, and compared the distribution of MICA-A alleles in HLA-B27 negative versus HLA-B27+ patients with AS. RESULTS We found that the frequency of MICA-A4 triplet repeat allele in a random Sardinia population is higher (53.2%) than in other Caucasian populations (around 20%); this allele is strongly associated with both HLA-B*2709 and B*2705. No significant difference between HLA-B27+ patients with AS and healthy controls was found: the MICA-A4 allele was present in more than 90% of subjects. MICA-A4 was found in 16 out of 20 HLA-B27 negative Sardinian patients with AS, with a frequency (80%) more similar to that of the HLA-B27+ group of patients than that of controls. CONCLUSION The high frequency of MICA-A4 allele in HLA-B27 negative patients with AS from Sardinia, suggests the presence within the HLA region of a susceptibility factor other and certainly weaker than B27. This factor is likely to be more easily found by analyzing genetically homogeneous populations like the Sardinian, characterized by a small number of very frequent haplotypes.

Abstract
Articles included in this review reflect the recent advances made in basic research and the clinical management of psoriatic arthritis in 1999. Some of these advances are destined to modify the current approach to the disease. The problems related to nosology and epidemiology, the two still controversial aspects, are discussed first. Genetic susceptibility to psoriasis and psoriatic arthritis, and the inciting role played by some bacteria, are confirmed, and attention is focused on the role of T cells, cytokines, adhesion molecules, and angiogenetic factors in the skin and synovial membrane. New classification criteria are provided and a simplified spectrum of the disease seems to emerge from clinical studies. Modern imaging techniques enable early articular changes to be discovered, support innovative pathogenetic hypotheses, and allow new therapeutic approaches.

Abstract
OBJECTIVE As the antiphospholipid syndrome (APS) is characterized by antibodies which bind negatively charged phospholipids either directly or mainly through different target epitopes located on the beta-2-glycoprotein-I (beta 2GPI) molecule, the aim of this study is to describe an additional target epitope for anti-cardiolipin binding. METHODS The binding characteristics of affinity purified anti-cardiolipin antibodies from a patient with monoclonal gammopathy associated with clinically overt APS were studied; inhibition studies were also carried out. These antibodies were used for the active induction of experimental APS. RESULTS The affinity purified anti-cardiolipin antibodies were found to bind a target epitope created by the complex of cardiolipin/beta 2GPI, while not reacting with a complex composed by another phospholipid (phosphatidylserine/beta 2GPI), as confirmed by direct binding and competition assays. Immunization of naive mice with this unique affinity purified anti-cardiolipin antibody resulted in the induction of experimental APS (thrombocytopenia, prolonged coagulation timed and fetal resorptions). The anti-cardiolipin/beta 2GPI injected mice developed high titers of mouse anti-cardiolipin/beta 2GPI antibodies with the same binding characteristics as the human antibody which was used for disease induction. CONCLUSION APS is a unique syndrome that is characterized by a diversity of pathogenic anti-phospholipid antibodies which may explain the diversity of clinical manifestations reported in patients.

Abstract
OBJECTIVE To test the prevalences and the clinical associations of anticardiolipin (aCL) and anti-beta2GPI (abeta2GPI) antibodies in a large series of European patients with systemic lupus erythematosus (SLE). METHODS 574 SLE patients from 7 European countries were tested for aCL and abeta2GPI by ELISA methods. RESULTS aCL of IgG, IgM, and IgA isotypes were detected in 22.8%, 14%, and 13.9% of the patients, respectively. IgG and IgM abeta2GPI were detected in 20% of the patients. The presence of aCL was highly associated with the presence of abeta2GPI. Medium-high titer IgG aCL and abeta2GPI were associated with thrombosis, with similar sensitivity, specificity, and positive predictive value. When present at medium-high titer, IgG aCL were associated with thrombocytopenia, IgM aCL with hemolytic anemia, and cerebrovascular accidents. IgA aCL with livedo reticularis and Raynaud's phenomenon. CONCLUSIONS aCL, when present at medium-high titer, are as important as abeta2GPI, as a risk factor for thrombosis. Medium-high titer aCL, but not abeta2GPI, are associated with other clinical features of the antiphospholipid syndrome.

Abstract
We report a case of bleomycin-induced scleroderma in a 35-year-old woman treated with chemotherapy for Hodgkin's disease. Approximately 6 months after the first chemotherapy cycle, the patient developed skin sclerosis in both arms. The lesion showed no signs of spontaneous clinical amelioration and treatment with steroids was unsuccessful. A partial remission of the skin sclerosis was instead obtained by the administration of D-penicillamine. A family history revealed other cases of autoimmune diseases and HLA typing showed the presence of antigens associated with scleroderma. The association between bleomycin therapy and scleroderma is discussed.

Abstract
We describe an unusual case of overlap between Takayasu's arteritis (TA) and systemic sclerosis (SSc). TA has been found in association with several diseases, but not with SSc. To our knowledge this is the first case report of TA associated with SSc in the literature. It is possible that the expression of the two diseases in our patient was influenced by the presence of genetic factors predisposing to both TA and SSc.

Abstract
In the present study we assessed the frequency and characteristics of the main causes of morbidity and mortality in SLE during a 5-year period and analyzed the prognostic significance for morbidity and mortality of the main immunologic parameters used in clinical practice. We started in 1990 a multicenter study of 1,000 patients from 7 European countries. All had medical histories documented and underwent medical interview and routine general physical examination when entered in the study, and all were followed prospectively by the same physicians during the ensuing 5 years (1990-1995). Four hundred thirteen patients (41.3%) presented 1 or more episodes of arthritis, 264 (26.4%) had malar rash, 222 (22.2%) active nephropathy, 139 (13.9%) fever, 136 (13.6%) neurologic involvement, 132 (13.2%) Raynaud phenomenon, 129 (12.9%) serositis (pleuritis and/or pericarditis), 95 (9.5%) thrombocytopenia, and 72 (7.2%) thrombosis. Two hundred seventy patients (27%) presented infections, 113 (11.3%) hypertension, 75 (7.5%) osteoporosis, and 59 (5.9%) cytopenia due to immunosuppressive agents. Sixteen patients (1.6%) developed malignancies, with the most frequent primary localizations the uterus and the breast. Several immunologic parameters (anti-dsDNA or antiphospholipid antibodies) were found to have a predictive value for the development of SLE manifestations during the period of the study. Forty-five patients (4.5%) died; the most frequent causes of death were divided similarly among active SLE (28.9%), infections (28.9%), and thromboses (26.7%). A survival probability of 95% at 5 years was found. A lower survival probability (92%) was detected in those patients who presented at the beginning of the study with nephropathy.

Abstract
In Sardinia, like in other Caucasoid populations, rheumatoid arthritis (RA) is significantly associated with HLA-DR4 and DR1 antigens. To discover which DR4 and DR1 alleles were associated with the disease we selected 22 Sardinian patients affected by RA. Fifty DR4+ and 28 DR1+ healthy individuals coming from the same geographical area were used as controls. In the Sardinian patients only two DRB1*04 alleles were observed: DRB1*0405 in 11 and DRB1*0403 in three patients. The DRB1*0102 allele was observed in two patients and DRB1*0101 in six patients. Hereditary predisposition to RA in Sardinia therefore seems to be almost exclusively associated with the DRB1*0405 and DRB1*0101 alleles which share the 67LLEQRRAA74-85VG86 epitope in the peptide binding groove.

Abstract
OBJECTIVES To evaluate, in a cohort of 566 patients with systemic lupus erythematosus (SLE) drawn from 11 European centres: (i) the prevalence of ANCAs and their subspecificities in a large series of European SLE patients; (ii) the possible associations of ANCA with the most common clinical manifestations of the disease; and (iii) whether ANCAs correlate with some of the autoantibodies commonly found in SLE. METHODS ANCA detection was performed by indirect immunofluorescence (IIF), and by ELISA for lactoferrin (LF), myeloperoxydase (MPO), proteinase3 (PR3) and lysozyme (LZ) subspecificities. RESULTS The prevalence of ANCA was 16.4% (IIF). The prevalence of LF was 14.3%, LZ 4.6%, MPO 9.3%, and PR3 1.7%. Our results show that ANCA is associated with certain clinical manifestations of SLE. In particular, positive correlations were found between IIF ANCA and serositis (p = 0.026), livedo reticularis (p = 0.01), venous thrombosis (p = 0.03) and arthritis (p = 0.04), while anti-LF antibodies were associated with serositis (p = 0.05) and livedo reticularis (p < 10(-3). Nevertheless, multivariate analysis demonstrated that other autoantibodies, such as aCL and SSA/Ro, are more closely correlated than ANCA with some of the aforementioned clinical features. CONCLUSION Our results demonstrate that ANCA are detectable in SLE sera and that some of them are associated with particular clinical manifestations. Whether ANCA plays a direct pathogenetic role in the vascular damage of SLE or only represents an epiphenomenon or a marker of disease activity remains to be elucidated.

Abstract
Lithium kinetics were studied in four manic-depressive women treated with calcitonin for post-menopausal osteoporosis. During calcitonin therapy all patients showed a significant decrease of lithium blood levels, and an increase in lithium renal clearance was observed in two out of two patients. According to these data, lithium therapy needs to be adjusted in patients undergoing concomitant treatment with calcitonin.

Abstract
The Arctic is still relatively pristine in nature, but it is also vulnerable to pollution because contaminants originating from midlatitudes are transported to the Arctic by atmospheric processes, ocean currents, and rivers (Muir et al., 1992). Recognition of this fact of Arctic vulnerability has resulted in a Declaration on the Protection of the Arctic Environment by eight Arctic countries. A manifest aim of this declaration is to develop an Arctic Monitoring and Assessment Program. We report here on the presence of measurable levels of polycyclic aromatic hydrocarbon-DNA adducts, including relatively high levels in Arctic beluga (Delphinapterus leucas). These results lend support to the value of developing biological assessment programs for Arctic wildlife.

Abstract
A prospective, open, multicentre, randomized study with a blinded radiological end-point was started in 1991. The aim of the study was to assess whether cyclosporin A (CyA) controls ongoing anatomical damage in active early rheumatoid arthritis (RA) better than conventional disease-modifying anti-rheumatic drugs (DMARDs) as used in everyday clinical practice. A total of 340 consenting patients with early RA (mean duration 1.4 yr) were recruited; 167 were randomized to CyA 3mg/kg per day and 173 to DMARDs. Hand, wrist and foot X-rays were blindly scored by a central committee of three radiologists using the Larsen-Dale method. Any side-effects were carefully recorded. The control of clinical symptoms was similar in both groups. Radiological evaluation of 284 patients (141 on CyA; 143 on DMARDs) after 12 months showed a significant decrease in the mean progression in the eroded joint count (1.3 +/- 3.1 vs 2.4 +/- 3.0, P < 0.001). There was also better maintenance on treatment with CyA than in the group treated with DMARDs (89.2 vs 77.5%, respectively; P = 0.002). CyA seems to offer greater control of ongoing anatomical joint damage in early RA than conventional DMARDs after 12 months.
