Cím:Calculation of the radioiodine dose for the treatment of graves' hyperthyroidism : is more than seven-thousand rad target dose necessary? / Laszlo Bajnok, Emese Mezosi, Endre Nagy, Jeno Szabo, Ilona Sztojka, Jozsef Varga, Laszlo Galuska, Andras Leovey

Megjegyzések:Some authors recently suggested a significant increase in the target dose of radioiodine treatment in Graves' disease. The aim of the present study was to investigate the impact of thyroid gland mass on the success rate of radioiodine treatment. For this purpose, the thyroid function of 105 consecutive Graves' patients was assessed 6 and 12 months after a 131I treatment and correlated to the gland mass. The patients were categorized according to the gland mass into small (< or = 30 g; 19 patients), medium size (31-50 g; 40 patients), and large size (> 50 g; 46 patients) groups (S, M, L groups, respectively). None of the patients received more than a 10,000-rad (100-Gy) target dose. During the calculation of administered 131I activity, late uptake measurement has also been routinely used, in addition to the usual maximal uptake parameter. The established effective half-life of 131I was highly variable (5 +/- 1.2 days; range: 2-7.6 days) and could not be predicted based on other clinical data without measuring an extended radioiodine uptake curve of the given patient. However, the correlation between the administered activity calculated from the complete set of uptake values and that of only a single late one was excellent (r = 0.99). Six months after the 131I treatment, hyperthyroidism was cured in 81% of patients with small and medium size thyroid glands, with 62% euthyroid and 19% hypothyroid ratios respectively. In the early phase of study for large goiters, the same linear mass activity function was used during calculation as in smaller glands. In these 17 patients the nonhyperthyroid result was comparable to the results of treatment of the small and medium size gland groups only after 1 year (77%), but the 6-month success rate was significantly lower (53%; p < 0.05). After obtaining these results, the usual 7000-rad target dose was increased to 8000-10,000 rad (depending on the gland mass) in another group of 29 patients with large thyroid glands that result in an acceptable 6-month success rate of 72%. In conclusion, instead of the "mCi 131I/g gland mass/maximal uptake" dose calculation, we suggest a method in which (1) the late 131I uptake measurement is taken into account and (2) for large goiters there is an additional dose adjustment, ie, increase is needed over the usual linear, size driven calculation. No overall increase of target dose over 10,000 rad is necessary if no antithyroid medication is given shortly before 131I treatment.

Cím:Prevalence of iodine deficiency and goitre during pregnancy in east Hungary / Mezosi E., Molnar I., Jakab A., Balogh E., Karanyi Z., Pakozdy Z., Nagy P., Gyory F., Szabo J., Bajnok L., Leovey A., Kakuk G., Nagy E. V.

Megjegyzések:OBJECTIVE: To assess the iodine nutritional status and the prevalence of goitre during pregnancy in a region of Hungary that appeared to be iodine sufficient in previous studies. DESIGN: A cross-sectional voluntary screening study was organized in which 313 pregnant women participated. METHODS: Urine iodine concentration and the volume of the thyroid gland were measured in every woman. In the presence of low urinary iodine concentrations, goitre, or both, thyroid function tests were performed. RESULTS: Iodine deficiency was found in 57.1% of the pregnant women, and was severe in 15.6%. The volume of the thyroid gland was enlarged in 19.2% of individuals. Nodular goitre was found in 17 women (5.4%). The frequency of goitre and the mean thyroid volume were increased in the group of iodine-deficient women. In the 89 cases of iodine deficiency or goitre, thyrotrophin concentrations were in the normal range; however, the free triiodothyronine:free throxine ratio was increased in 97% of them, indicating that the thyroid gland was in a stimulated state in these individuals. CONCLUSIONS: Iodine deficiency with high prevalence of goitre was recognized among pregnant women in an area that previously appeared to be iodine sufficient. An unexpected mild iodine deficiency was also noted in the non-pregnant control group. Reassessment and continuous monitoring of iodine nutritional status is warranted even in populations that are apparently considered to be 'at no risk' of iodine deficiency, especially in pregnant women. Regular administration of iodine, starting at preconception or in early pregnancy and continuing during the period of nursing, is recommended in these regions.

Cím:The role of technetium-99m methoxyisobutylisonitrile scintigraphy in the differential diagnosis of cold thyroid nodules / Emese Mezősi, Laszló Bajnok, Ferenc Gyory, Jozsef Varga, Ilona Sztojka, Jeno Szabo, Laszlo Galuska, Andras Leovey, György Kakuk, Endre Nagy
Dátum:1999
ISSN:1619-7070
Megjegyzések:Various diagnostic techniques have been successfully used in the clinical management of cold nodules; however, the decision on whether to employ surgery or a conservative treatment is not always easy. This study was designed to appraise the diagnostic value of technetium-99m methoxyisobutylisonitrile (MIBI) scintigraphy in the assessment of cold nodules detected using (99m)Tc-pertechnetate. Fifty-two patients were included in the study. All had already been selected for surgery, based on their clinical and laboratory findings, including fine-needle aspiration biopsy. The total number of cold nodules on (99m)Tc-pertechnetate scans was 59. The thyroid scan was performed 20-40 min after i.v. injection of 400 MBq of (99m)Tc-MIBI. Uptake of MIBI in thyroid nodules was compared with that in the surrounding normal thyroid tissue, and a score of between 0 and 3 was assigned to each nodule as follows: 0, cold; 1, decreased; 2, equal; 3, hot. Definitive histology revealed nodular goitre in 24 cases, adenoma in 19, thyroiditis in 1, differentiated cancer in 12, medullary cancer in 2, and anaplastic cancer in 1. None of the degenerative nodules were hot on MIBI scan, while the adenomas showed a variety of MIBI imaging patterns, most frequently the score 3 pattern. In the diagnosis of differentiated thyroid cancer the sensitivities of score 3 and score 2+3 MIBI uptake patterns were 83% (10/12) and 100%, respectively. The score 3 MIBI uptake pattern had a specificity of 100% and a positive predictive value of 100% with respect to thyroid (benign and malignant) neoplastic diseases, whereas a specificity of 72% and a positive predictive value of 43% were observed in the detection of differentiated cancer. After a cold nodule had been detected using (99m)Tc-pertechnetate, a second scan with high MIBI uptake increased by 7.8 times the probability that this nodule would be a differentiated cancer. In conclusion, (99m)Tc-MIBI scintigraphy is a useful method in the differential diagnosis of cold thyroid nodules if the primary aim is to differentiate degenerative from neoplastic diseases rather than to differentiate benign from malignant nodules. High MIBI uptake considerably increases the probability of a differentiated thyroid cancer and facilitates immediate surgical removal, while decreased uptake actually excludes it. We suggest a combination of fine-needle aspiration biopsy and MIBI scan as a routine diagnostic approach to cold thyroid nodules.

Cím:Graves' ophthalmopathy : eye muscle involvement in patients with diplopia / Endre V. Nagy, Judit Toth, Ildiko Kaldi, Judit Damjanovich, Emese Mezosi, Agota Lenkey, Laszlo Toth, Jeno Szabo, Zsolt Karanyi, Andras Leovey

Megjegyzések:Background: Diplopia identifies patients with eye muscle involvement in Graves' ophthalmopathy (GO).Objective: To identify clinical parameters that could eliminate the need for magnetic resonance imaging(MRI) to assess the activity of inflammation in the eye muscles of GO patients with diplopia.Methods: In 43 patients with GO with recently developed diplopia, orbital ultrasound and MRI wereperformed. Muscle diameters and MRI T2 relaxation times were measured, and the amount of orbitalconnective tissue was calculated from MRI scans and compared with ultrasound readings, diplopiagrades, degree of protrusion, ocular pressure, tear production, antibody levels and hormonalparameters of thyroid function.Results: No correlation was found between diameters of 233 extraocular muscles measured by MRIand by ultrasound. For each of the four muscles, there was a diameter above which ultrasound wasalways unreliable. MRI data were used in further analysis. Of the muscles examined, the inferiorrectuses were the most frequently enlarged ? at least one, in 93% of cases. Medial, lateral and superiorrectuses were enlarged in 59%, 37% and 34% of the orbits respectively. The pattern of muscleinvolvement of the two orbits tended to be symmetric (r?0.49, P?0.003), particularly for the medialrectuses (r?0.90, P?0.000). Proptosis correlated with the sum of the muscle diameters for a giveneye (right eye: r?0.54, P?0.003; left eye: r?0.57, P?0.001), but it failed to correlate with theamount of orbital connective tissue. In 53% of the patients, normal T2 relaxation times were found inall eight muscles. There was only a weak correlation between muscle thickness and T2 relaxation time(r?0.49, P?0.003), indicating that muscle enlargement alone is not a sign of disease activity. Theseverity of diplopia was independent of T2 relaxation time. The amount of orbital connective tissueshowed a negative correlation with the greatest T2 relaxation time for a given eye (r? ?0.52,P?0.004); this suggests that disease types exist that have predominant muscle involvement andpredominant connective tissue expansion. No correlation between connective tissue expansion andproptosis, diplopia grade, muscle thickness or disease duration was found ? that is, connective tissueexpansion is not a major factor in diplopia. Both muscle and connective tissue findings wereindependent of thyroid function.Conclusion: Ultrasound and MRI eye muscle diameter readings do not correlate, because of the inherentinaccuracy of orbital ultrasound. Muscle enlargement alone does not mean oedematous swelling andactive disease. Neither ultrasound, nor any combination of 11 clinical and laboratory parametersprovided the degree of information on muscles and connective tissue that was obtainable by MRI. Inunclear cases of recently developed diplopia, before orbital decompression surgery, in the case oftreatment failure or if, for any other reason, imaging is needed in GO, MRI is the method of choice.

Cím:Heterogeneous signal pathways through TSH receptors in porcine thyroid cells following stimulation with Graves' immunoglobulin G. / Szabó J., Fóris G., Keresztes T., Csabina S., Varga Zs., Bakó Gy., Mezősi E., Nagy E., Paragh Gy., Leövey A.
Dátum:1998
Megjegyzések:We compared different signal transduction pathways through thyroid stimulating hormone receptor (TSH-R) in porcine thyroid cells (PTC) following stimulation with thyroid stimulating hormone (TSH) and 11 thyroid stimulating immunoglobulin samples (TSI) obtained from patients with Graves' disease. DESIGN: Following stimulation with TSI, the level of inositol trisphosphate (IP3) and [Ca2+]i, as well as the membrane bound protein kinase C (PKC) activity and the intensity of the arachidonic acid (AA) cascade, were determined in PTC. RESULTS: Seven out of eleven TSI samples activated PTC through IP3 generation, elevated [Ca2+]i from the intracellular pools, exhibited verapamil-insensitive membrane-bound PKC activation, and enhanced release of [14C]AA derivates (however, one of the samples was also able to take up Ca2+ from the extracellular space). Four out of eleven TSI samples did not activate the phospholipase C (PLC) system in which case the Ca2+ signal occurred only in the presence of extracellular Ca2+, the membrane bound PKC activation was verapamil sensitive, and in two of these four TSI samples, the AA release was extremely high. CONCLUSIONS: The simultaneous examination of the majority of the known signal pathways using TSI samples showed that TSI samples from different patients activate thyroid cells through different pathways. Their effects differ from that of TSH and, to a certain extent, from each other. The results give a certain new insight into the intracellular mechanisms exerted by TSI.

Cím:Parameters of respiratory burst and arachidonic acid metabolism in polymorphonuclear granulocytes from patients with various thyroid diseases / Szabó J., Fóris G., Mezösi E., Nagy E. V., Paragh G., Sztojka I., Leövey A.
Dátum:1996
Megjegyzések:The oxidative processes (oxygen consumption, superoxoid anion generation, arachidonic acid cascade) of human polymorphonuclear granulocytes (PMNs) obtained from patients suffering from thyroid disorders of autoimmune origin (Graves' disease and Hashimoto's thyroiditis), and non autoimmune origin (toxic adenoma) were investigated. All Graves' and toxic adenoma patients were hyperthyroid. Hashimoto's thyroiditis patients were euthyroid. Healthy age and sex matched volunteers served as controls. The results are as follows: 1) In PMNs from both hyperthyroid groups (Graves' disease and toxic adenoma), independently from the autoimmune origin of the disease, a significantly increased Antimycin A sensitive mitochondrial oxygen consumption and a slightly increased superoxide anion generation were detected. 2) In both autoimmune thyroid disease groups (Graves' disease and Hashimoto's thyroiditis)--depending on the functional state of the thyroid gland--a significantly altered intracellular killing activity was measured. 3) An increased arachidonic acid cascade--triggered by opsonized zymozan (OZ)--was detected in both autoimmune thyroid diseases. The increased arachidonic acid cascade was sensitive to phospholipase A2 inhibiting Mepacrin treatment. 4) The PMNs from both autoimmune thyroid diseases produced large amount of leukotriens (LTs)--LTC4 and LTB4--after stimulation through their Fc receptors but the synthesis of prostagalandins (PGs) has not changed. There are no data indicating local, specific effects of circulating leukotriens in the thyroid gland itself, but based on authors' data, their general, regulating role on both the endocrine-- as well as on the immune system--seems to be plausible.
