Gastric emptying in hyperthyroidism.

OBJECTIVES: We undertook a prospective study to survey gastric emptying of a solid meal in patients with hyperthyroidism until euthyroidism was reached after pharmacological treatment with thiamazole. METHODS: Eleven women (aged 33.2 +/- 3.2 SE yr) with recently diagnosed hyperthyroidism participated in the study. Thyroid function parameters and gastric emptying were examined on three occasions, before treatment, during the third week of treatment, and after euthyroidism was restored. The control group was composed of 12 age-matched healthy women (aged 34.5 +/- 2.3 yr). Gastric emptying of a 390-kcal 99mTc-labeled solid meal was continuously recorded under a gamma camera over 90 min. A power-exponential model was used for analysis of the gastric emptying course. Three gastric emptying parameters were computed: t1/2, the gastric half-emptying time, S, the curve shape parameter, and K, the slope of the curve. RESULTS: Pretreatment solid phase gastric emptying of the patients was not statistically significantly different from that of the healthy control subjects: t1/2, 82.8 +/- 4.9 vs 93.5 +/- 6.0 min; S, 0.996 +/- 0.103 vs 1.032 +/- 0.064; and K, 8.42 +/- 0.47 vs 7.64 +/- 0.39 min(-1) x 10(-3). Gastric emptying during the third week of treatment did not change in comparison with pretreatment gastric emptying: t1/2, 84.3 +/- 8.2 min; S, 1.014 +/- 0.123; and K, 8.92 +/- 1.12 min(-1) x 10(-3). On the other hand, a slight increase in rate of gastric emptying was observed after the restoration of euthyroidism (t1/2, 74.6 +/- 5.8 min, and K, 9.65 +/- 0.76 min(-1) x 10(-3), p < 0.05 vs healthy control subjects for both parameters), but no significant change was observed in the shape parameter (S, 0.980 +/- 0.066). CONCLUSIONS: In women with hyperthyroidism, gastric emptying of solids does not differ significantly from that observed in age-matched healthy control subjects and remains unaffected during pharmacological treatment. After restoration of euthyroidism, a slight but statistically significant increase in the rate of gastric emptying occurs in patients as compared with healthy control subjects.

Gastric emptying in hypothyreosis.

The purpose of this study was to compare the solid phase gastric emptying (GE) in hypothyreotic patients before treatment and after euthyreosis has been reached. Ten female patients (aged 44.8 +/- 9.5[SD] y) with recently diagnosed hypothyroidism were included in the study. Their thyrometabolic state and GE were examined before treatment and after a median of 5 1/2 months (range 2 1/2-12 1/2), i.e., when euthyreosis was achieved. The control group consisted of 12 healthy women (aged 34.5 +/- 8.1y). GE of a 390-kcal 99mTc-labelled solid meal was continuously recorded under a gamma camera during 90 min. A power-exponential model was used for the analysis of the GE course. Compared to the controls, the solid phase GE of the hypothyreotics was characterized by a significantly lower curve shape parameter S (0.745 +/- 0.217 vs. 1.032 +/- 0.223, p < 0.01) and slope of the curve K (4.8 +/- 2.2 min-1.10(-3) vs. 7.6 +/- 1.3 min-1.10(-3), p < 0.01). Restoration of euthyreosis resulted in an increase of both parameters, making the GE pattern no longer statistically significantly different from that encountered in healthy subjects. The treatment did not affect the gastric half emptying time T1/2 (median: 125 min and 130 min before and after the treatment, respectively; healthy controls: 94 min). A wide variation of individual GE data was found either before or after the treatment, and in a few cases delayed GE persisted despite an effective substitutive treatment. The GE kinetics was, however, in no way related to the severity of the disease. Further research on the pathogenesis of this phenomenon is warranted.

[Cognitive function in patients with systemic sclerosis].

Central nervous system involvement is seldom reported in patients with systemic sclerosis (SSc). Cognitive functions were determined in 21 patients with definite SSc and 42 healthy controls. Thyroid function was also measured in order to eliminate the effect of hypothyroidism on cognitive functioning. It was found that the SSc patients with normal thyroid function showed defective long-term and recent memory, learning ability, criticism, perception and visuo-perceptual skills, their simple reaction time was prolonged. Similar but less advanced cognitive defects were shown in the SSc patients with overt or latent hypothyroidism. The obtained results indicate that the central nervous system involvement is more common in patients with SSc than it has been reported earlier.

[The influence of salmon calcitonin on the soluble form of VCAM-1 (CD 106) and E-selectin (CD 62E) in serum of patients with atopic bronchial asthma].

The aim of the study was to evaluate the effect of salmon calcitonin (CT) on serum level of soluble form of VCAM-1 (sVCAM-1 = soluble vascular cell adhesion molecule-1) and E-selectin (sE-selectin = soluble E-selectin) in patients with atopic bronchial asthma. Twenty-four individuals divided into 4 groups (6 persons each) were investigated. The first group consisted of patients with chronic moderate bronchial asthma, the second and third groups consisted of patients with mild bronchial asthma and the fourth group K consisted of healthy individuals. The patients of the first and second group were treated with CT at a dose of 100 i.v./days s.c. for three days. The patients of the third group were given placebo (phychological saline) in similar way as CT. The indices were measured before the treatment with CT or placebo and on the 4th day of the treatment. It was found that CT treatment decreased sVCAM-1 in serum only in the patients of the first group (p < 0.05) but had no effect upon sE-selectin level. The obtained results suggest that CT interfered into mechanisms of inflammation involving adhesion molecules in patients with bronchial asthma.

Premictional volume and contractility of the urinary bladder in patients with systemic sclerosis.

Ultrasonographic measurements of the urinary bladder in 21 women with systemic sclerosis (SSc) revealed abnormal volume of the bladder in about 65% of patients; 6/21 had a smaller bladder and 7/21 had a larger bladder than the controls. The volume of the remaining urine after miction was higher in 7 patients. Fibrosis of the bladder wall leading to a small rigid bladder and ureteral obstruction resulting in a large bladder with low contractility are suggested as phenomena involved in disturbed function of the urinary bladder in SSc patients. Patients with symptoms lasting more than 14 yrs. were found to have larger premictional volume of the bladder than those with short-lasting disease. No correlation between age, number of deliveries and bladder volume was found.

[Investigations concerning the effect of nabumetone on gastric mucosa].

The investigations were carried out in 9 patients (6 women and 3 men) with rheumatoid arthritis or degenerative joint disease. All subjects were given 1000 mg nabumetone (NA) in a single daily dose at the evening, during 21 days. Before and after the therapeutic course, endoscopic examination of the upper digestive tract was carried out. On day at the begin and on the 22nd day of the NA treatment, the gastric transmucosal electric potential difference (PD) was determined, in (a) standard condition, (b) after intragastric application of 1000 mg NA, and (c) after a similar application of 1000 mg of acetylsalicylic acid (AAS). On the contrary to the effect caused by AAS (p < 0.001), NA did not result any significant change of the PD (p > 0.05), neither after a single nor after 21 day-long application (the lowest PD value before the NA therapeutic course was after a single NA dose -45.8 +/- 2.7 mV and after a single dose of AAS -40.4 +/- 2.45 mV; after the end of the NA therapy course the values were: after additional NA dose -46.7 +/- 3.5 mV and after AAS -40.5 +/- 2.7 mV) Endoscopically, any changes of the upper digestive tract mucosa which could be related to the NA therapeutic course were not detected.

[Influence of energy expenditure and other factors on the incidence of arterial hypertension in employees with some types of employment in Tychy].

The aim of the work was to evaluate the incidence of arterial hypertension in the inhabitants of Tychy, a city polluted by ecotoxins, in relation to the energy expenditure of professional work, in consideration of overweight, cholesterolaemia, uricemia, alcohol consumption, age and sex. Investigations were carried out on 1964 individuals (1392 men, 572 women) divided in 5 groups with different intensity of professional work. Serum uric acid and cholesterol levels were determined in all examined persons. Incidence of the obesity was also considered. The authors conclude that the risk of arterial hypertension in the examined individuals of Tychy is average 17.4% for both men and women, and it decreases with enhanced energy expenditure at professional work for men. Arterial hypertension appears in subjects from obesity, hyperuricaemia and drinking more than 4.0 dl of pure ethanol per week.

[Evaluation of stomach emptying in patients with hyperthyroidism].

The study aimed at the evaluation of the kinetics of gastric emptying (GE) of a solid meal in hyperthyroid patients during a pharmacological treatment with thiamazole until the moment of euthyroid restoration. Fourteen female patients ((33.4 +/- 2.6 y, mean +/- SE) with recently diagnosed hyperthyreosis took part in the study. Twelve age matched healthy women (34.5 +/- 2.3 y) constituted a control group (C). Every patient underwent the GE examination before treatment (I). In 12 patients the GE was reexamined on the 3rd treatment week (II). After the achievement of euthyroid, which happened after 4.5 mo (median; interquartile range 2.0 to 7.3 mo), a third GE measurement was taken in 13 patients (III). The GE of a 99mTc-labelled solid meal was measured with the use of a gamma camera. Time-activity curves from the gastric region of interest were used, after subjection to appropriate corrective procedures, to calculate the mean gastric transit time (MTT 90) and the fraction of the test meal retained in the stomach after 90 min (F90). Before the treatment and on the third week of management the GE of hyperthyroidism was not statistically significantly different from that of healthy controls (MTT90:39.44 +/- 0.30 min [I] 39.31 +/- 0.64 min [II] and 40.06 +/- 0.29 [C]; F90:46.6 +/- 1.9% [I], 47.9 +/- 3.7% [II] and 50.8 +/- 2.4% [C]). The restoration of euthyreosis was accompanied by a slight but statistically significant increase in the GE -p < 0.05 in the case of F90 vs the pre-treatment situation. Also the patients' GE was found then to be slightly but statistically faster than in healthy controls (MTT90:38.72 +/- 0.39 min [III], and F90: 42.2 +/- 2.3% [III] -p < 0.05 vs [C] for both parameters). We conclude that in hyperthyreotic women the GE of solids does not differ significantly from age-matched healthy female controls and remains unchanged during a pharmacological treatment. After achievement of euthyreosis a slightly but statistically significantly faster GE is observed in the patients when compared to healthy controls.

[Evaluation of gastric emptying in patients with hypothyroidism].

The study aimed at the evaluation of the gastric emptying (GE) kinetics in hypothyroid patients before and after a substitutive treatment with L-thyroxin. Twelve female hypothyroid (aged 45.3 +/- 8.7 years, mean +/- SD) and a control group of 12 healthy women (aged 34.5 +/- 8.1 years) were examined. The GE of a 99mTc-labelled solid meal was measured with the use of a gamma camera in every patient before the treatment, and in 10 of them a repeat GE examination was performed after the restoration of euthyroid; the median duration of the treatment was 5.5 mo (range 2.5 to 12 mo). The mean gastric transit time (MTT90) and the fraction of the test meal retained in the stomach after 90 min (F90) were statistically significantly greater in untreated hypothyroid than in healthy controls (MTT90: 42.01 +/- 1.86 min patients vs 40.06 +/- 1.00 min controls, p = 0.0043; F90: 64.3 +/- 15.4% patients vs 50.8 +/- 8.2% controls, p = 0.0173). In ten patients in whom a second GE measurement was taken after the achievement of euthyroid, a slight increase of the GE was observed (MTT90:41.46 +/- 1.49 min before vs 41.04 +/- 1.81 min after the treatment, NS) which was then no longer statistically significantly different from that of the healthy controls. No relationship was found between the GE and the severity of clinical symptoms of hypothyroidism. GE remained, however, slowed in some patients despite the restoration of euthyreosis. We conclude that: (I) long-lasting hypothyreosis is accompanied by a slightly slowed GE of solids, and (II) restoration of euthyreosis does not imply a parallel improvement of the hypothyroidism-associated delay in GE.

[The influence of heart infarction on the concentration of aminoterminal type III procollagen peptide in blood serum].

UNLABELLED: The reconstructive processes in a heart infarction pertain also the fibrous tissue sceleton, of which the main element are collagen fibres. The aim of the study was determination of variability of a specific collagen synthesis marker, i.e. the serum aminoterminal type III procollagen peptide (PIIINP) and its correlation with hydroxyproline (HP), hydroxylysin (HL) concentration as well as activity of creatine kinase (CK) and aspartate aminotransferase (AspAT) in serum after heart infarction. The investigations were carried out in 30 patients with a heart infarction with Q wave (group I), in 20 subjects with a heart infarction without Q wave (group II) and in 30 healthy subjects, comprising the C group. All these parameters were determined on the 1st, 2nd, 3rd, 5th and 10th day after onset of infarction. In comparison to the C group, in group I on the 1st day the PIIINP concentration was 3-fold higher and in group II it 2 1/2-fold higher (C = 4.3 +/- 1.8; I = 14.2 +/- 3.9; II = 10.4 +/- 2.0 micrograms/l; p < 0.001). In group I even on the 10th day the concentration did not return to normal values, instead in group II it reached the values x + SD in C group after 5 days. There was no significant correlation between concentration of PIIINP and all other examined parameters stated. Heart infarction with a Q wave caused a relatively highest (% of mean values in C group) increase in CK and AspAT activity, PIIINP held a medial position, while HP and HL the lowest. After infarction without a Q wave the relative elevation of PIIINP concentration was near to the AspAT and HP increase. CONCLUSIONS: 1. the differences of serum PIIINP concentration are probably resulted by the magnitude of heart infarction. 2. During 10 days after the onset of heart infarction the serum concentration of PIIINP does not show any correlation with HP, HL and enzymatic heart infarct markers. 3. The results indirectly show, that the scar formation after heart infarction begins already on the first day.

[Effect of heart infarction on levels of type I procollagen carboxyterminal peptide in blood serum].

The aim of the study was determination of the influence of heart infarction on the blood serum level of type I procollagen carboxyterminal peptide (PICP) and its covariability with concentration of hydroxyproline (HP) and hydroxylysine (HL) as well as activity of creatine kinase (CK) and aspartate transferase (AspAT). The investigations were carried out in 30 patients with a heart infarction with Q wave (group I) and in 20 subjects with a heart infarction without Q wave. The control group comprised 30 healthy subjects. The determination of all parameters was performed on the 1st, 2nd, 3rd, 5th and 10th day after the infarct onset. On the 1st day of heart infarction, the concentration of PICP in serum was (x +/- SD): gr. I-235 +/- 33, gr. II-209 +/- 8, gr. C-65 +/- 17 micrograms/l. There was no co-variability of PICP concentration and the values of all other determined parametres. The authors conclude: 1. the increase of serum PICP concentration is connected probably with the magnitude of heart infarction, 2. the reconstruction process of the heart fibrous tissue and scar formation begins already on the first day of infarction onset, 3. during 10 days after infarction onset the serum PICP concentration does not correlate with HP, HL as well as the enzymatic heart infarct indices, namely CK and AspAT.

[Interdigestive gallbladder volume and and meal-induced gallbladder emptying in patients with diabetes].

The aim of the study was to find whether the type of diabetes and the duration of this disease causes any influence on gallbladder (GB) emptying, after exclusion of possible effect of obesity and a hyperglycaemia over 7 mmol/l (126 mg%) on this phenomenon. The investigations were carried out in 44 subjects with diabetes mellitus, among them 22 with type I and 22 with type II. These groups were divided according to disease duration: shorter or longer than 3 years. Two control groups (CI, CII) comprised each 20 healthy subjects. The age of CI and CII corresponded to the age of diabetes groups type I and II, respectively. All subgroups as well as the control groups were matched according to sex percentage structure, body mass index (BMI) and body surface (BS). In groups with type I and II diabetes, the number of cases with diabetic neuropathy was comparable. There was not found any significant (p > 0.05) influence of diabetes on the interdigestive GB volume, neither non-standardized nor standardized with regard to standard BS (1.73 m2). In comparison to the control groups, after a test meal, there was in all diabetic groups a statistically significant (0.001 > p < 0.05) reduction of GB emptying observed. This diminution was most expressed in the group with long-lasting type I diabetes.

Serum amino-terminal propeptide of type III procollagen in patients with hyperthyroidism or hypothyroidism during therapy.

Changes in serum amino-terminal type III procollagen propeptide (PIIIPN) and hydroxyproline were compared with indices of thyroid function in 33 patients with hyperthyroidism and 16 patients with hypothyroidism before and after treatment. Control values were obtained from 26 healthy individuals. Hyperthyroidism was shown to be associated with an increased level of PIIIPN and hypothyroidism with a decreased PIIIPN level. An increase in PIIIPN was found in 100% of hyperthyroid patients and a decrease in 31% of those with hypothyroidism, while hydroxyproline increased in only 54% of patients with hyperthyroidism and its level was decreased in only 6% of patients with hypothyroidism. Correlation between PIIIPN and thyroxine and triiodothyronine levels was shown. The results obtained suggest that PIIIPN is a valuable index of tissue response to thyroid hormones.

[Effect of misoprostol, a synthetic prostaglandin E analog, on levels of serum C-peptide in serum and glucose tolerance].

The aim of the study was to investigate whether oral application of misoprostol (MI), which is an analogue of prostaglandin E1, does change the secretion of insulin and the blood glucose level. The investigations were carried out in 15 subjects, aged 21-40 yrs, with a gastric or duodenal ulcer and without any disturbances of the digestive tract motility. In 7 of them (group A), without stated diabetes a single oral dose of 400 mg MI versus placebo (PL) and 15 min later 75 g glucose p.o., was applied in randomized order, on different days, in fasting state. In 8 subjects with mild diabetes type II (gr B) MI versus PL and after 15 min. i.v. 1.0 mg glucagon was similarly administered. In both groups the concentrations of glucose and C-peptide in blood were determined. In comparison to PL, the application of MI did not cause any statistically significant differences of C-peptide in serum and blood glucose levels neither before and after oral glucose loading nor after i.v. administration of glucagon. Statistically not significant were also the differences in AUC (p > 0.05).
