Hungarian Immunology - 2004;3(02)

[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.]

[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.]

[Toll-like receptors and epithelial cells]

SZEGEDI Gyula

[Toll-like receptors have been extensively studied in the last few years. These receptors are involved in the mechanisms how microbes and infections are linked to natural immunity and some autoimmune-inflammatory processes. Here author reviews the latest news on Tolllike receptors with much emphasis on their role on epithelial cells. Therapeutic strategies targeting Toll-like receptors are also discussed.]

[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.]

[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.]

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.

Acute motor and sensory axonal neuropathy associated with Sjögren’s syndrome

ETHEMOGLU Ozlem, KOCATÜRK Özcan, TARINI Zeynep Emine

Sjögren’s syndrome (SS) is an autoimmune disease with mononuclear cell infiltration and destruction of the lacrimal gland and salivary glands, which cause dryness of the eyes and mouth. The most common neurological condition seen in SS is peripheral neuropathy. Initial manifestation of SS as an acute fulminant peripheral neuropathy is extremely rare. We report a 42-year-old patient presenting with acute motor sensory-axonal neuropathy in the presence of SS. She showed partial response to intravenous immunoglobulin but favourable clinical improvement was seen after initiation of corticosteroid treatment.

[NOVEL RESULTS ON SYSTEMIC LUPUS ERYTHEMATOSUS]

KISS Emese, GERGELY Péter, SZEGEDI Gyula

[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.]

[SIMULTANEOUS CENTRAL AND PERIPHERAL NERVOUS SYSTEM INVOLVEMENT IN SYSTEMIC LUPUS ERYTHEMATOSUS]

ILNICZKY Sándor, KAMONDI Anita, ARÁNYI Zsuzsanna, VÁRALLYAY György, GAAL Barbara, SZIRMAI Imre, NAGY György

[Systemic lupus erythematosus is a frequent autoimmune disease, affecting several organs, including the brain, spinal cord and nerves. Cerebral vasculitis, transverse myelitis and polyneuropathy are the most common neurological manifestations. We report a case of a 46 years old woman who suffered incomplete transverse myelitis in her age of 44. After 2 years the second relapse presented with arthralgias, painful paraesthesias and weakness of the lower limbs. Neurological signs suggested involvement of the central and the peripheral nervous system. Based upon clinical and laboratory findings systemic lupus erythematosus was diagnosed. Magnetic resonance imaging revealed two hyperintense lesions on T2 weighted scans within the cervical spinal cord. The brain scan was normal. Protein content was slightly elevated in the cerebrospinal fluid, with normal cell count. Electrophysiological examinations diagnosed a subacute sensory-motor axonal polyneuropathy. On methylprednisolone treatment her condition improved. Simultaneous development of central and peripheral lesions of the nervous system in cases with systemic lupus erythematosus may lead to a challenge to establish the diagnosis.]
