[OBJECTIVE - To assess the relation between clinical features and the presence of SS-A(Ro) and SS-B(La) autoantibodies in systemic lupus erythematosus. PATIENTS - The data of 200 patients with definite systemic lupus erythematosus were analysed. SSA( Ro) and SS-B(La) antibodies were assessed by enzyme immunoassay. RESULTS - 40.5% of systemic lupus erythematosus' patients were SS-A(Ro) and/or SS-B(La) antibody positive (’positive group’); the majority of such patients displayed both antibodies, 16.5% had SSA( Ro) antibodies alone, while only 2% has SS-B(La) antibodies alone. There were no differences in the occurrence of arthritis, secondary antiphospholipid syndrome and hematologic manifestations between the positive and negative groups; serositis was more common in the positive group. Skin manifestations, in particular subacute cutaneous lupus erythematosus and urticaria vasculitis were more frequent in the positive group, while kidney and central nervous system involvation, in particular severe forms were less frequent. Secondary Sjögren's syndrome occurred exclusively in antibody positive patients. Sm, RNP and Scl-70 antibodies were more frequently found in the positive group. CONCLUSIONS - The presence of SS-A(Ro) and/or SS-B(La) antibodies in systemic lupus erythematosus has some prognostic significance; in antibody-positive patients there is an increased risk for skin lesions (in particular subacute cutaneous lupus erythematosus and urticaria vasculitis) and secondary Sjögren’s syndrome and a decreased risk for severe nephritis or central nervous system involvement.]

[β-endorphin concentrations in the cerebrospinal fluid and serum in systemic lupus erythematosus and multiple sclerosis patients]

BARACZKA Krisztina, BENDER Tamás, BARNA István, GÉHER Pál

[INTRODUCTION - The aim of the present study was to investigate the cerebrospinal fluid and serum β- endorphin levels in several diseases characterized by central nervous system demyelinisation. PATIENTS AND METHODS - Ten patients with systemic lupus erythematosus complicated with demyelinating syndrome and ten patients with chronic progressive form of multiple sclerosis were selected. Concentrations of β-endorphin were measured using a high sensitive, specific radioimmunoassay. Statistical significance (Wilcoxon test, two variable t test) and correlations (Spearman and Pearson correlations coefficients) were calculated. RESULTS - β-endorphin concentration in the cerebrospinal fluid did not differ in multiple sclerosis and systemic lupus erythematosus patients compared to the controls.]

[Diagnostic value of MRI in patients with juvenile dermatomyositis]

CONSTANTIN Tamás, PONYI Andrea, BALÁZS György, SALLAI Ágnes, DANKÓ Katalin, FEKETE György, KARÁDI Zoltán

[Diagnosis of juvenile dermatomyositis is based on the presence of proximal muscle weakness, characteristic skin lesions, muscle enzyme elevation in the serum, and may requires the performance of invasive procedures such as electromyography and/or muscle biopsy. Magnetic resonance imaging (MRI) is considered to be an objective non-invasive tool to detect muscle involvement for diagnosis as well as for follow-up studies. We report a case of a 12 years old girl with definitive juvenile dermatomyositis. She received glucocorticoid therapy and achieved remission of the disease. After a long-term relapse free period, she was presented with severe proximal muscle weakness and normal creatinine kinase levels. The laboratory studies did not reveal acute inflammation or infection. In this case MRI was diagnostic to the relapse of juvenile dermatomyositis, with an increased STIR (short tau inversion recovery) signal of proximal muscles. The muscle involvement detected by MRI correlated with functional ability. After she achieved clinical remission, further follow-up MRI scans demonstrated that the affected muscles had returned to normal signal intensity. Findings of dermatomyositis on MRI scans include increased signal intensity in the affected muscles, perimuscular edema, chemical-shift artifact, and increased signal intensity in subcutaneous tissue. MRI is a sensitive technique and proposed to be a good indicator for an early diagnosis of the disease. MRI may also help to guide the muscle biopsy and may enhance the sensitivity of histological examination. After completion of therapy, MRI may be used for monitoring the progress of the disease as signal intensity of affected muscles returns to normal. MRI is also helpful, if the diagnosis is suspected but has not been formally evaluated.]

[Experiences on cyclosporin-A treated childhood atopic dermatitis resistant to other therapies]

SZAKOS Erzsébet, SZEGEDI Andrea, SÓLYOM Enikõ, HUNYADI János

[BACKGROUND - Cases of six children suffering from serious form (resistant to conventional therapy) of atopic dermatitis are presented and the experiences regard of treatment with cyclosporin A (Sandimmun Neoral-microemulsion form) are summarised. PATIENTS - The average age of the 4-16 year-old children (three girls, three boys) was 9.9 years. The skin process started at infantile age. The cyclosporin A was used during 12-85 weeks, in a maximal dose of 3.5-5 mg/body weight kg/day. The patients received locally creams or ointments to moisture their skin continuously and if it was necessary, corticosteroid creams or ointments for a few days. RESULTS - The therapeutic response was excellent in five cases and poor in one case. The short time therapies resulted transient, the long time therapies long acting effect. There was no side effect indicating the stop of cyclosporin A therapy. Three children presented body weight elevation slightly higher than the age-related physiologic change. Epstein-Barr and cytomegalovirus infection with severe submandibular lymphadenopathy appeared in a patient and transient hypertrichosis in the case treated for 85 weeks. DISCUSSION - The authors propose treating severe childhood atopic dermatitis resistent to other therapeutic possibilities with cyclosporin A. The adequate follow up, monitoring of clinical and bloodchemical parameters are important.]

Posterior reversible encephalopathy syndrome as an initial manifestation of systemic lupus erythematosus

AYAS Özözen Zeynep, ÖCAL Öncel Ruhsen, GÜNDOGDU Aksoy Asli

Posterior reversible encephalopathy syndrome (PRES) is a disorder which is diagnosed with its characteristic clinical and radiological findings, typically resolves with treatment. The prevalence of PRES in systemic lupus erythematosus (SLE) patients is not exactly known. A systemic disorder frequently appears as a presenting symptom in SLE. However, in rare cases, the disease starts with a neurological manifestation. Here we report a 35-year-old woman presenting with a headache and blurred vision. She had neurologic symptoms and cerebral lesions on magnetic resonance imaging (MRI) suggesting PRES. The patient was diagnosed with SLE during the etiological investigation of PRES. In this article, we aimed to emphasize that PRES as an initial presentation of SLE.

[Autoantibodies against α-fodrin in patients with Sjögrens’s syndrome]

SZÁNTÓ Antónia, CSÍPŐ István, ZEHER Margit

[INTRODUCTION, PATIENTS AND METHODS - In this study, the authors examined the presence of the IgA and IgG type autoantibodies against the 120 kDa α-fodrin in the sera of patients affected with primary and secondary Sjögren’s syndrome, rheumatoid arthritis and systemic lupus erythematosus, being treated in the Department of Clinical Immunology of the 3rd Department of Internal Medicine, at the University of Debrecen. As a control population, the sera of healthy blood donors were used. RESULTS - Due to their findings, the presence of autoantibodies against the α-fodrin was significantly higher in patients with primary Sjögren’s syndrome than in the control group. The presence of these autoantibodies occurred significantly more often in patients affected with secondary Sjögren’s syndrome associated to RA and SLE, than in these polysystemic autoimmune diseases without sicca-syndrome. Interestingly, they couldn’t find any connection between the presence of autoantibodies against α-fodrin and the occurrence of SS-A/Ro or SS-B/La autoantibodies. There was no correlation in primary and secondary Sjögren’s-syndrome between the extraglandular symptomes or the swelling of the salivary glands and the presence of the anti-α-fodrin autoantibodies. CONCLUSIONS - The autoantibodies against α- fodrin might be important in the diagnosis of the juvenile Sjögren’s syndrome and other juvenile autoimmune diseases, in the early diagnose of Sjögren’s syndrome, especially in the lack of anti-SSA/ Ro and anti-SS-B/La.]

[MCP-1 (monocyte chemoattractant protein-1) G/A and T-bet (T-helper promoter factor) C/G polymorphisms in primary Sjögren’s syndrome and systemic lupus erythematosus]

KOVÁCS Attila, KONCZ Ágnes, ENDREFFY Emőke, ARANKA László, PETRI Ildikó, ELLER József, SZALAI Csaba

[INTRODUCTION - Monocyte chemoattractant protein- 1 (MCP-1) is a β-chemokine involved in the attraction and accumulation of mononuclear granulocytes towards the site of inflammation. One of the transcriptional factors of T-cells is called T-bet. PATIENTS AND METHODS - The authors investigated the MCP-1-2518 G/A and T-bet 310 C/G (His33Gln) polymorphisms evaluating the distribution of the specific genotypes in 45 patients with primary Sjögren's syndrome (pSS), 51 patients with systemic lupus erythematosus (SLE), and in 320 healthy blood donors as the control group. MCP-1-2518 G/A and T-bet 310 C/G polymorphisms were detected with molecular genetic methods from the purified genomic DNA. RESULTS - The frequency of the MCP-1-2518 AG heterozygous genotype decreased tendentiously only in SLE patients, while the frequency of the MCP-1 AA homozygous genotype increased comparing to the control group (13.7% vs. 5.9%; Pearson’s χ2 test=6.125, ns.). Analyzing the genotype frequency for the MCP-1 wild (GG) and AA homozygous genotypes in pSS group, the MCP-1 AA homozygous genotype proved to be more frequent comparing to the control group (82.8%:17.2% vs. 90.7%:9.3%; Pearson’s χ2 test 1.755, ns). These relations showed only tendentious association in the SLE group (81.6%:18.7% vs. 90.7%:9.3%; Pearson’s χ2 2.811, p=0.094, ns.) There was not any significant correlation between the investigated MCP-1- 2518 G/A and the T-bet 310 C/G polymorphisms and the TNF-α -308 G/A and -238 allele polymorphisms. The frequency of T-bet was equal in relation with heterozygous (CG) to wild CC genotype in the investigated two autoimmune disorders. The GG homozygous genotype for T-bet could not be found in SLE and pSS groups, likely to be a protective factor. CONCLUSIONS - The above mentioned polymorphisms didn’t show any significant correlation with TNF-α -308 and -238 allele polymorphisms. The further research of the MCP-1 G/A and T-bet C/G polymorphisms is important, because of their possible prognostic importance for SLE and pSS.]

[Systemic lupus erythematosus is an autoimmune disorder. It stands at the focus of medical interest: basic scientists, clinicians and innovative biotechnologists all pay attention to lupus. Authors of this article present the novel scientific results on the etiopathogenesis, clinical and laboratory characteristics of SLE. Furthermore, authors discuss diagnostic problems and the possible therapeutic modalities. One of the most important results is the characterisation and mapping of the susceptibility genes as well as the analysis of their functional features. More and more is known about the relationship between natural and adaptive immunity, about the cooperation of T and B cells. The abnormalities of intracellular biochemical processes and signal transduction pathways have been cleared. The importance of cytokine network and infective agents in the pathogenesis of SLE has largely been investigated recently. With regards to the outcome of the disease, there is growing attention paid on chronic organ damages, such as end-stage renal disease, osteoporosis and atherosclerosis - in connection with the increased life expectancy. Evidence accumulates on the importance of immune-inflammatory processes in the initiation and perpetuation of osteoporosis and atherosclerosis. There is an urgent need for validated biomarkers which can predict the susceptibility, prognosis, clinical manifestations, activity and severity of SLE. To follow and measure the effectiveness of treatment is also required. Although the principals of lupus management have not changed, novel immune modulators, biological therapy and non-medical treatments (e.g. stem-cell transplantation) have become available. Further research and clinical observations may help to find the real place of such therapeutics.]

[Analysis of short-term and long-term survival and causes of death in patients with systemic lupus erythematosus]

TARR Tünde, KISS Emese, SZEGEDI Gyula, ZEHER Margit

[INTRODUCTION - In systemic lupus erythematosus (SLE), both short-term and long-term survival rates have improved worldwide. We analysed retrospectively the short-term and long-term survival data and causes of death at a single center. These data were compared with previous survival data recorded at the same centre and published in international studies. PATIENTS AND METHOD - The data of 550 patients with SLE were analysed between 1970 and 2009. We examined the effect of clinical symptoms, age, severity and onset of the disease and the applied immunosuppressive treatment on survival, using the Kaplan-Meier method. RESULTS - Survival rates at 5, 10, 15 and 20 years after the diagnosis were 98%, 94%, 90% and 89%, respectively. Late onset, neuropsychiatric symptoms and severe SLE were found to be prognostic factors. Manifestations affecting other organs and the applied immunosuppressive therapy did not influence survival rates. During the study period, 57 out of the 550 patients (10.4%) died. The main causes of death were cardiovascular complications (50.9%), infections (21%), and malignancies (12.3%). CONCLUSIONS - Our results show that among patients with SLE, it is mostly longterm survival that has increased, owing to the close control of patients. The increase in cardiovascular mortality highlights the importance of regular screening.]
