[Autoimmun thyroiditis presence in patient with Hodgkin’s disease in remission]

BÍRÓ Edit, BAKÓ Gyula, SZEGEDI Gyula, ILLÉS Árpád

[INTRODUCTION - It is known that the incidence of hypothyroidism is higher in long term survivor patients with Hodgkin's disease, and it is supposed to be the result of treatment, such as neck radiotherapy. The author believe that other etiologic factors may also play a role in the development of hypothyroidism. PATIENTS AND METHODS - Looking for the possible causes of hypothyroidism, the thyroid function of 151 patients treated for Hodgkin's disease since 1970 were examined. These patients with Hodgkin's disease in complete remission for at least one year and their data on thyroid autoantibody positivity [antithyroid peroxidase antibody (aTPO), antihuman thyroglobulin antibody (aHTG), TSH antireceptor antibody (TRAK)] were analysed. RESULTS - Among the patients with antibody positive 26 received ultrasound scanning and fine needle aspiration cytology of the thyroid, which confirmed autoimmun thyroiditis. There were no significant differences between the mean age, histologic subtypes and stage of the disease between the patients with antibody positive those with antibody negative. A significantly greater number of women in the group of antibody positive patients was found and thyroid dysfunction (two cases of hyper, and 13 cases of hyperthyroidism) was revealed in 53.6% of the patients. Though antibody positivity was more frequent in patients having been treated by neck irradiation, but no significant relationship was found between the form of Hodgkin’s disease treatment and the development of thyroiditis. Thus the authors cannot confirm the assumption according to which the autoantigens released from the thyroid gland damaged by neck irradiation for Hodgkin's disease would provoke the development of thyroiditis. Since - independently of the type of treatment received - the incidence of thyroiditis is higher in patients with Hodgkin's disease, it is probable that immune regulation disorders may also play a role in its development and thus hypothyroidism is the result of a multi-factor process. DISCUSSION - These results underline the importance of a regular control of thyroid hormones and thyroid autoantibodies in follow up Hodgkin’s disease patients. Levothyroxine administered as an isohormone treatment may inhibit the development of hypothyroidism in patients with thyroiditis may improve the quality of their life.]

[Changes in the signal transduction of T-lymphocytes caused by hyperglycemia]


[AIMS - Lately the altered calcium balance of different cell types (eg.: erythrocytes, platelets, neutrophil granulocytes) was described in diabetes mellitus. It is also known that patients with diabetes mellitus suffer from various infections more often then healthy individuals because of immunological malfunctions. But the mechanism of these changes is still unclear. In order to investigate the effect of hyperglycemia on the function of immunocompetent cells we established an in vitro diabetes model by culturing human T cells (Jurkat cells) at different glucose concentrations for one week. Then we measured the basal cytosolic calcium level, the calcium signal after ionomycin or anti-CD3 treatment and the tyrosinephosphorylation of signal transducing proteins as well as the fructosamine level of cellular proteins. MATERIALS AND METHOD - Cytosolic free calcium levels were detected by flow cytometry using ion selective fluorescent indicator (Fluo-3 AM). Calcium signals of Jurkat cells were measured after ionomycin or monoclonal anti-CD3 antibody (OKT3) treatment. We also measured the tyrosine-phosphorylation on flow cytometer after anti-CD3 stimulation using indirect immunfluorescent labeling with monoclonal antiphospho- tyrosine antibody. The non-enzymatic glycation of cellular proteins was determined by measuring the fructosamine levels of cell lysates. RESULTS - The higher concentration of extracellular glucose resulted in concentration-dependent elevation of basal cytosolic free calcium level in Jurkat cells. Reduced calcium signal (activation capacity) was measured either after ionomycin or monoclonal anti-CD3 antibody treatments in cells kept at hyperglycemic conditions. In addition, the time kinetics of calcium signal following anti- CD3 activation was found prolonged in the hyperglycemic cells. The tyrosine-phosphorilation of hyperglycemic Jurkat cells also proved to be impaired. High glucose concentrations in tissue culture medium caused increase in the glycation of T-cell proteins. CONCLUSIONS - We propose that increased glycation of proteins involved in calcium transport and/or intracellular signal transduction of T-cells may account for our observations.]

[Ocular myositis]

KISS Emese, FACSKÓ Andrea, DÉVÉNYI Katalin, DANKÓ Katalin, ZEHER Margit

[INTRODUCTION - Dermato-/polymyositis is an autoimmune disorder, which belongs to the idiopathic inflammatory myopaties. It involves skeletal muscles in form of weakness and inflammatory infiltrates. Characteristic skin lesions are present in dermatomyositis. Other organs may also be affected mainly in the presence of myositis specific autoantibodies. The inflammation usually involves the proximal muscles of extremities. CASE REPORT - In the present work we report the case of a 52-year-old woman. In the previous history the removal of rectal adenocarcinoma was remarkable in 1994. After that she received chemotherapy. She complied for severe headache and pain in the right eye in 2000 October, therefore a skull CT was performed, indicating thickening of rectus medalis muscle within orbital cavity. There was an enhancement of contrast material in the muscle. Glaucoma was excluded. Neurologist suspected the presence of myositis and indicated 0.5 mg/kg corticosteroid therapy. Soon after the left eye became painful, but due to the corticosteroid treatment both eyes became painless. A control orbital CT was completely negative in 2000 November. Immunology consultancy revealed a mild proximal muscle atrophy in both lower extremities, but CPK and LDH enzyme levels were normal, EMG was characteristic for mild chronic nerve lesion. The biopsy, taken from the involved proximal muscle of lower extremity, did not show inflammatory infiltration. Complete screening for cancer was negative. Thyroid gland disease could be excluded. Immune laboratory data were negative, autoantibodies, including anti-Jo1, could not be detected. Based on the results a rare disease, ocular myositis was diagnosed. Considering the clinical improvement, the withdrawal of corticosteroid therapy was offered. Stringent immunology and oncology follow-up is required. CONCLUSION - In relation to our case report, we discuss clinical symptoms of orbital myositis, diagnostic procedures to identify the disease and also differential diagnostic considerations.]

[Anti-synthatase syndrome]


[The idiopathic inflammatory myopathies (IIM) are autoimmune diseases, characterized by symmetric proximal muscle weakness. Over the last several decades, many abnormalities of the cellular and humaral immune systems of IIM patients have been described. Some of these are autoantibodies unique to the IIM (the myositis specific autoantibodies MSA). The MSAs are antigen-driven, arise months prior to the onset of myositis, correlate in titre with disease-activity. Studies in the recent years proved that clinically and immuno-geneticaly different disease entities can be defined using myositis specific auto-antibodies. Their use make the serological classification. Myositis specific autoantibodies make it possible to define more homologies subgroups within polymyositis/dermatomyositis that may support the adequate treatment. The most common MSA is the antihistidyl- transfer RNA synthetase (anti-Jo-1), which can be found in 5-30% of patients with myositis. Patients with anti-synthatase antibodies tend to have characteristic clinical presentation of fever, small joint arthritis, intestinal lung disease, Raynaud's phenomenon, mechanic's hands and severe myositis. Sera of 65 PM/DM were tested for anti-Jo- 1 antibody. 15 patients (23%) had anti-Jo-1 antibody (10 PM, 5 DM). The patients with anti-Jo- 1 antibody has a significantly higher incidence of interstitial lung disease, arthritis, fever and Raynaud's phenomenon. These patients needed not only corticosteoid therapy, but other immunosupressive treatment. All 15 patients presented with the onset of weakness between February and July. The determination of myositis-specific autoantibodies has produced more homogenous grouping within the polymyositis/dermatomyositis patients.]

[Monitoring of effectiveness of ramipril-amlodipine fixed combination, a non-interventional trial (Ramona study). Subgroup analysis of patients with chronic kidney disease]


[Hypertension and chronic kidney disease are independent cardiovascular risk factors. The 5th Cardiovascular Consensus Conference has recommended chronic kidney disease in high-risk category. In chronic kidney disease hypertension is observed in most cases. In patients with chronic kidney disease blood pressure targets are as 140/90 mmHg blood pressure below must be achieved without overt proteinuria. In chronic kidney disease combined antihypertensive therapy treatment should be initiated according the Hungarian Society of Hypertension recommendations. Aims: Monitoring the effectiveness and safety of the fix combination of ramipril/amlodipine Egiramlon® therapy in chronic kidney disease suffering from mild or moderate hypertension despite antihypertensive treatment. Patients and methods: Open, prospective, phase IV clinical observational study, which involved known chronic kidney disease (age over 18 years) with mild or moderate hypertension. Ramipril/amlodipine fixed combination (5/5, 5/10, 10/5 or, 10/10 mg) were administered or titrated in three visits, during the 4 months of trial period. The doses of the fixed combination drugs were determined individually during the visits by the 923 physicians involved in the study. The target blood pressure value was <140/90 mmHg according the new guidelines of ESH/ESC. Results: 70.1% of total patient (9169) was fulfilled the protocol during the four month of trial (6423 patients). In this population 194 patients suffered from chronic kidney disease. The age of patients was 68.52±1.84 (mean±SD) years, 85 (43.8) women and 109 (56.2%) men. 74.74% of total patients with chronic kidney disease has reached target blood pressure at the end of 4th month (primary endpoint). The blood pressure has decreased significantly (all p<0.0001) from 158.04/90.46±9.97/8.30 mmHg (1. visit) to 138.77/82.12±10.68/7.21 mmHg 2. visit and to 130.40/78.59±7.56/5.75 at the and of trial (3. visit), it means -27.64/- 11.87 mmHg decrease from the beginning of the 4th Month (3. visit). eGFR level increased significantly from 46.3±16.49 ml/min/1,73m2 to 49.0±19.58 ml/min/1,73m2. Patients suffered from chronic kidney disease have tolerated well the various doses of fixed combination of ramipril/amlodipine, and adverse events have no occurred correlation of treatment.]

[Risk estimates of advanced chronic kidney disease and predicting mortality in dialyzed patients]


[In mostly the second part of the last decade lots of epidemiological study have been released about the progression of the chronic kidney disease (CKD) and theirs connection with the risk of death. The fact that lots of nephrologist from all over the world (from Canada to New-Zealand) are pretty much interested in this topic is absolutely proved by national (REIN Study – French Registry) and international (KDIGO Controversies Conference, DOPPS 1-5, or the European AROII Study) researchers with these epidemiological questions in their focus. The risk estimation facts that are able to show the life expectancy of patients with CKD 3-5 (expected time to dialysis or mortality risk before renal replacement therapy – RRT) and the early or hopefully longer survival odds of the dialyzed ones could be very useful not only for the medical stuff but also for the patients. In case of the predialyzed patients the focus has to be on the Bansal score and also on the Kidney Failure Risk Equation (KFRE) scores (with 4 and 8 variable); on the other hand in dialyzed patients the REIN score that prognose a short-term survival and the Cohen model (both are easy calculated with webcalculators) are in the highlight of importance. There is not a big difference (2- 7%) in validated researches between the prognosed and the real survival dates. Despite of this prediction has to always be evaluated individually in favour of the best decision we can make for the patients and in order to choose the right treatment: conservative therapy, dialysis or transplantation.]

[Lipid-lowering treatment in chronic kidney disease in light of new studies and recommendations]


[Summary – Chronic kidney disease (CKD), which affects 10-14% of the population, dramatically increases the incidence and severity of cardiovascular (CV) disease, leading to death in the majority of patients before kidney replacement therapy. The current CV risk scorecards in CKD significantly underestimate the real risk and are therefore not applicable. For CV risk assessment it is recommended to use the combined GFR/proteinuria table also, which is used for CKD classification, was also adopted by the Hungarian CV Consensus Conference last year. The benefit of cholesterol- lowering treatment has also been demonstrated in CKD, and a 1 mmol/l reduction in LDL-c, as in the general population, reduces the incidence of major CV events by 20%. Recent clinical trials have clearly indicated that the lower the LDL-c values achieved, the lower the risk of future CV events, and therefore the new recommendations have tightened the LDL-c values to be achieved. ]
