We aimed to evaluate prognostic efficacy of cortisol and TFTs in critically ill poisoned patients admitted to toxicology intensive care unit(ICU).METHODS: In a prospective study of consecutively enrolled subjects admitted to the toxicology ICU, lab analyses included TFTs(total T3 and T4 as well as TSH) and cortisol levels drawn between 8 am–10 am during period of the first 24 hours post-ingestion/exposure. Simplified Acute Physiology Score Ⅱ(SAPS Ⅱ) and Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ) were recorded. All scores were compared to detect the best prognostic factor. Type of poisoning was also included.RESULTS: In 200 patients evaluated, 129 were male and mean age was 31 years. In general, SAPS Ⅱ, T4, and cortisol could prognosticate death. After regression analysis, only cortisol had such efficacy(P=0.04; OR=1.06; 95%CI=1.05–1.08; cut-off=42 μg/d L; sensitivity=70%; specificity=82%). Between aluminium phosphide(ALP)-and non ALP-poisoned patients, level of consciousness, mean arterial pressure, and cortisol level could prognosticate death in ALP poisoning(all Ps<0.001 in both uni and multivariate analyses). Median(interquartile range; IQR) GCS was 7(6, 10) and 15(8, 15) in non-ALP and ALP-poisoned patients(P<0.003). SAPS Ⅱ and APACHE Ⅱ could not prognosticate death at all.CONCLUSION: Cortisol best prognosticated outcomes for subjects admitted to the toxicology ICU. Its level is higher in ALP-poisoned patients probably due to the higher stress while they remain conscious till the final stages of toxicity and are aware of deterioration of their clinical condition or may be due to their significantly lower blood pressures.展开更多

METHODS： A study population of 3 749 residents aged 20-79 years without previously diagnosed thyroid disease was available for analyses. Serum TSH was used to assess thyroid function. Cholelithiasis was defined by either a prior history of cholecystectomy or the presence of gallstones on ultrasound. Logistic regression was performed to analyze independent associations between thyroid function and cholelithiasis. RESULTS： There were 385 persons （10.3%） with low （〈0.3 mIU/L）, 3 321 persons （88.6%） with normal and 43 persons （1.2%） with high serum TSH levels （〉3 mIU/L）. The proportion of cholelithiasis among males and females was 14.4% and 25.3%, respectively. Among males, there was an independent relation between high serum TSH and cholelithiasis （OR 3.77; 95%-CI 1.06-13.41; P〈0.05）. Also among males, there was a tendency towards an elevated risk of cholelithiasis in persons with low serum TSH （OR 1.40; 95%-CI 0.96-2.02; P= 0.07）. In the female population, no such relation was identified. CONCLUSION： There is an association between thyroid and gallstone disease with a gender-specific relation between hypothyroidism and cholelithiasis.展开更多

The rats were exposed to high fluoride drinking water （45 mg F-L^-1 from 100 mg NaF L-1）, low dietary iodine （0.0855 mg kg-1）, or both together in order to assess the effects of these three regimens on the thyroid function of the offspring rats. After the animal model was established, the offspring rats were bred and 10-, 20-, 30-, 60-, and 90-d-old rats were used for the experiment. The treatments for the offspring rats were the same as those of their parents. In comparison with control rats, the relative thyroid glands were changed by three regimens, but the mean values of thyroid weight in the experimental groups saw no marked difference. Serum TT3 levels were increased in all stages in the low iodine （LI） group. In the high fluoride （HiF） group, increase in TT3 levels was observed except in 20-d-old rats. Decrease in TT3 at 20- and 90-d and increase in TT3 at 30- and 60-d were found in HiF＋LI group. Serum TT4 levels first saw an increase, and then dropped in the LI and HiF＋LI group. However, an increase in TT4 was found in the HiF group. The levels of TSH in serum rocketed at d 20, and then dropped in the next stages in experimental groups. The results suggested that thyroid disorder could be induced by high flroride in drinking water, low iodine diet, or both of them. Exposure time to fluoride or low iodine diet was one of the important factors that fluoride can induce the development of thyroid dyfunction.展开更多

The objective of this research is to critically analyze the age and gender based variations of thyroid volume and thyroid hormone levels in the hospital based euthyroid subjects. Methodology: A total of 221 euthyroid subjects aged 1 - 86 years were selected to observe the normal thyroid size by ultrasonography at Department of Radiology and the thyroid function test values (FT3, FT4 and TSH) of 2413 euthyroid subjects aged (Results: The best fitted equations with significant correlation coefficients and p Conclusion: The thyroid size first increases and then decreases whereas the thyroxin level first decreases and then increases with aging. Left lobe volume is almost same for both genders and right lobe volume is higher in males. The thyroid size in menarche and menopause periods of females is larger than that of males. Such age- and gender-specific changes recommend the new refer-ence ranges for the normal thyroid functions.展开更多

Methods The thyroid samples from 14 cases of diagnosed AFTAs were analyzed, with normal thyroid specimens adjacent to the tumors as controls. The 155 base pairs DNA fragments which encompassed the third cytoplasmic loop and the sixth transmembrane segments in the TSH receptor gene exon 10 were amplified by Polymerase chain reaction (PCR) and analyzed by the single-strand conformation polymorphism (SSCP). Direct sequencing of the PCR products was performed with Prism Dye Terminator Cycle Sequencing Core Kit. Results 6 of 14 AFTA specimens displayed abnormal migration in SSCP analysis. In sequence analysis of 3 abnormally migrated samples, one base substitution at nucleotide 1957 (A to C) and two same insertion mutations of one adenosine nucleotide between nucleotide 1972 and 1973 were identified. No mutations were found in controls. Conclusion This study confirmed the presence of TSH receptor gene mutations in AFTAs; both one-point substitution mutation and one-base insertion mutation were found to be responsible for the pathogenesis of AFTAs.展开更多

A total of 226 volunteers i.e. 128 male and 98 female were screened at Radiology Department King Abdul-Aziz University Hospital. They were categorized as smokers and non- smokers;the number of smokers was 99 cases i.e. 48 Cigarette smokers and 51 Shisha smokers, and the non-smokers were 127 cases. The information was gathered via a questionnaire distributed at the radiology department. Ultrasonography of thyroid and thyroid function test were performed for 166 participants;and data were analyzed Using SPSS version 22 and Microsoft excel. The study was carried out based on random selection and findings revealed that most of the cases were in the age group between 20 to 30 years old, high body mass index (BMI) was 33.1 kg/m2 in persons above 60 years old and the highest percentage smokers in the age group from 20 to 30 years (40.02%). Ultrasonography of thyroid showed 96 (58%) normal cases, 46 (28%) abnormal “solid” cases and 24 (14%) abnormal “cyst” cases. A lower proportion of cigarette and shisha smokers (15.4% and 5.6% respectively) had an enlarged thyroid gland compared to no cigarettes or shisha smokers (47.9% and 47.3% respectively). The difference between these frequencies was statistically significant (Chi-square = 9.446 and 11.424, p = 0.002 and p = 0.001 for cigarette and shisha smoking respectively). Consequently, it can be concluded from this research that there are no direct significant values correlating smoking habit to thyroid volume or function. However, it is always recommended not smoke due to other well-known threats.展开更多

Thyroid function is also affected by goitrogenic substances in some plant foods, like cassava. Aim: This study aims to assess thyroid function status and its association to consumption of foods containing goitrogenic substances. Methods: A cross sectional study was done on a total of 65 pregnant women attending Sawla Health Center, South Ethiopia. Serum samples were collected and analyzed for TSH, total T4 and total T3 by using ELISA kit. Data on consumption of foods containing were obtained from food frequency questionnaire. Results: The median TSH of the first, second and third trimesters, respectively are 2.57, 1.86 and 2.42 mIU/L, which are within the reference interval (0.30-6.20 mIU/L) of the test kit. The median total T4 values (9.8, 10.0 and 10.3 μg/dl in the first, second and third trimesters, respectively) were also within the reference interval (4.8-11.6 μg/dl) of the test kits. The median total T3 in the first (2.60 ng/ml) and third (2.35 ng/ml) trimesters were elevated, but it was within the reference interval (0.69-2.02 ng/ml) in the second trimester (1.92 ng/ml). Though statistically non-significant median TSH was increased in women grouped as cassava consumers and M. stenopetala consumers while median total T4 values were decreased in these groups. Conclusion: The study subjects have normal thyroid function as the median values of TSH and total T4 were within the reference interval of the test kit. Frequent consumption of cassava and Moringa stenopetala may affect thyroid function.展开更多

The control group was given oral placebo, while the treatment group was given selenium yeast. The expression levels of thyroid function [including thyroid stimulating hormone (TSH), free triiodothyronine (FT3) and free thyroxine (FT4)], immune response [including thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TGAb), interferon-γ (IFN-γ), interleukin-4 (IL-4)] and oxidative stress [including malondialdehyde (MDA), glutathione peroxidase (GPx) and superoxide dismutase (SOD)] were observed and compared between the two groups.Results: The two groups showed significant changes in auxiliary diagnosis, immune response and oxidative stress. Before treatment, there was no significant difference in the levels between the two groups. After treatment, there was no significant difference in the above indexes between the control group and that before treatment. There was no significant difference in thyroid function related indexes between the treatment group and the control group. The levels of TPOAb, TGAb, IFN-γ and MDA in the treatment group were significantly lower than those before treatment and in the control group, while the levels of IL-4, GPx and SOD were significantly higher than those before treatment and in the control group.Conclusions: Selenium supplementation can stabilize thyroid function, reduce the level of thyroid antibody production, and improve immune response and oxidative stress response in HT patients.展开更多

Method: 90 patients with epilepsy who visited our hospital from January 2015 to May 2018 were selected as the observation group and 90 healthy volunteers were selected as control group. All patients in the observation group were treated with oxcarbazepine alone. T lymphocyte subsets, IgA, IgG, IgM, T3, T4, FT3, FT4, TSH, hs-CRP and Hcy in observation group were detected before treatment, 3 months after treatment and 6 months after treatment. The results were compared with those of the control group. Results: The levels of CD3+ and CD4+ in the control group were (65.25±9.51)% and (43.29±6.74)% respectively, which were higher than those in the observation group (P<0.05). The levels of CD8+, IgA and IgG in the control group were (22.40±6.41)%, (2.22±0.51) g/L, (9.99±1.28) g/L respectively, which were lower than those in the observation group (P<0.05). The levels of CD3+ and CD4+ in the observation group after 3 months and 6 months of treatment were significantly higher than those before treatment (P<0.05). The levels of CD8+, IgA and IgG in the observation group after 3 months and 6 months of treatment were significantly lower than those before treatment (P<0.05). There was no significant difference in the level of IgM between the observation group and the control group at each time point (P>0.05). The levels of thyroid hormones in the observation group before treatment and 3 months after treatment were not significantly different from those in the control group (P>0.05). The FT4 of the observation group was (14.98±1.03) pmol/L 6 months after treatment, which was significantly lower than that of the control group before treatment and 3 months after treatment (P<0.05). The levels of T3, T4, FT3 and TSH at each time point in the observation group were not significantly different from those in the control group (P>0.05). Before treatment, there was no significant difference in hs-CRP and Hcy levels between the observation group and the control group (P>0.05). The levels of hs-CRP and Hcy in the observation group were (4.82±0.67) mg/L and (13.36±1.51) umol/L respectively after 3 months of treatment. The levels of hs-CRP and Hcy in the observation group after 3 months of treatment were significantly higher than those before treatment and in the control group, and the difference was statistically significant (P<0.05). The levels of hs-CRP and Hcy in the observation group were (4.99±0.47) mg/L and (16.83±1.94) umol/L respectively after 6 months of treatment. The levels of hs-CRP and Hcy in the observation group were significantly higher than those in the control group after 3 months of treatment and before treatment (P<0.05). Conclusion: Oxcarbazepine can effectively improve the immune function of epilepsy patients, but with the prolongation of medication time, it may have adverse effects on thyroid function, hs-CRP and Hcy.展开更多

In the present work, thyroid function of pregnant women from Benin republic was studied. Two hundred forty (240) pregnant women, without thyroid disease history, have been included in the study. A blood sample was drawn for measurement of TSH, free T3 and free T4 serum levels. From the first to the third trimester, plasma levels of free T3 and free T4 decreased when plasma levels of TSH increased. Using recommendations of the 2011 American Thyroid Association (ATA) guidelines, thyroid dysfunction was observed in 24.17% of subjects. Hypothyroidism was present in 22.50% of subjects with 19.17% of subclinical hypothyroidism, 0.83% of overt hypothyroidism and 2.50% of hypothyroxinemia and hyperthyroidism was observed in 1.67% of subjects. An increase from 15.52% to 28.07% was observed in the frequency of hypothyroidism from the first to the third trimester of pregnancy. When an upper cut-off value of 4 mU/L was used for TSH, as recommended in the 2017 ATA guidelines, prevalence of thyroid disorders was 14.58% with 12.91% of hypothyroidism but no hypothyroidism was observed in women in the first trimester of pregnancy. A rise in hypothyroidism frequency was observed when pregnant women age increased. Hypothyroidism was very common in pregnant women in Benin. To allow accurate assessment of thyroid status in pregnant women in Benin, pregnancy specific range for plasma level of TSH and thyroid hormones should be established.展开更多

文摘Objective To examine the mechanistic of organochlorine-associated changes in lung function.Methods This study investigated 76 healthy older adults in Jinan,Shandong Province,over a fivemonth period.Personal exposure to organochlorines was quantified using wearable passive samplers,while inflammatory factors and thyroid hormones were analyzed from blood samples.Participants’lung function was evaluated.After stratifying participants according to their thyroid hormone levels,we analyzed the differential effects of organochlorine exposure on lung function and inflammatory factors across the low and high thyroid hormone groups.Mediation analysis was further conducted to elucidate the relationships among organochlorine exposures,inflammatory factors,and lung function.Results Bis(2-chloro-1-methylethyl)ether(BCIE),was negatively associated with forced vital capacity(FVC,–2.05%,95%CI:–3.11%to–0.97%),and associated with changes in inflammatory factors such as interleukin(IL)-2,IL-7,IL-8,and IL-13 in the low thyroid hormone group.The mediation analysis indicated a mediating effect of IL-2(15.63%,95%CI:0.91%to 44.64%)and IL-13(13.94%,95%CI:0.52%to 41.07%)in the association between BCIE exposure and FVC.Conclusion Lung function and inflammatory factors exhibited an increased sensitivity to organochlorine exposure at lower thyroid hormone levels,with inflammatory factors potentially mediating the adverse effects of organochlorines on lung function.
文摘BACKGROUND: Prognostic value of cortisol and thyroid function tests(TFTs) has previously been evaluated in medical ICUs. We aimed to evaluate prognostic efficacy of cortisol and TFTs in critically ill poisoned patients admitted to toxicology intensive care unit(ICU).METHODS: In a prospective study of consecutively enrolled subjects admitted to the toxicology ICU, lab analyses included TFTs(total T3 and T4 as well as TSH) and cortisol levels drawn between 8 am–10 am during period of the first 24 hours post-ingestion/exposure. Simplified Acute Physiology Score Ⅱ(SAPS Ⅱ) and Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ) were recorded. All scores were compared to detect the best prognostic factor. Type of poisoning was also included.RESULTS: In 200 patients evaluated, 129 were male and mean age was 31 years. In general, SAPS Ⅱ, T4, and cortisol could prognosticate death. After regression analysis, only cortisol had such efficacy(P=0.04; OR=1.06; 95%CI=1.05–1.08; cut-off=42 μg/d L; sensitivity=70%; specificity=82%). Between aluminium phosphide(ALP)-and non ALP-poisoned patients, level of consciousness, mean arterial pressure, and cortisol level could prognosticate death in ALP poisoning(all Ps<0.001 in both uni and multivariate analyses). Median(interquartile range; IQR) GCS was 7(6, 10) and 15(8, 15) in non-ALP and ALP-poisoned patients(P<0.003). SAPS Ⅱ and APACHE Ⅱ could not prognosticate death at all.CONCLUSION: Cortisol best prognosticated outcomes for subjects admitted to the toxicology ICU. Its level is higher in ALP-poisoned patients probably due to the higher stress while they remain conscious till the final stages of toxicity and are aware of deterioration of their clinical condition or may be due to their significantly lower blood pressures.

文摘AIM： To investigate those associations using data of the population-based Study of Health in Pomerania. METHODS： A study population of 3 749 residents aged 20-79 years without previously diagnosed thyroid disease was available for analyses. Serum TSH was used to assess thyroid function. Cholelithiasis was defined by either a prior history of cholecystectomy or the presence of gallstones on ultrasound. Logistic regression was performed to analyze independent associations between thyroid function and cholelithiasis. RESULTS： There were 385 persons （10.3%） with low （〈0.3 mIU/L）, 3 321 persons （88.6%） with normal and 43 persons （1.2%） with high serum TSH levels （〉3 mIU/L）. The proportion of cholelithiasis among males and females was 14.4% and 25.3%, respectively. Among males, there was an independent relation between high serum TSH and cholelithiasis （OR 3.77; 95%-CI 1.06-13.41; P〈0.05）. Also among males, there was a tendency towards an elevated risk of cholelithiasis in persons with low serum TSH （OR 1.40; 95%-CI 0.96-2.02; P= 0.07）. In the female population, no such relation was identified. CONCLUSION： There is an association between thyroid and gallstone disease with a gender-specific relation between hypothyroidism and cholelithiasis.

文摘Thirty-two Wistar rats were divided randomly into four groups of eight with six females and two males in each group. The rats were exposed to high fluoride drinking water （45 mg F-L^-1 from 100 mg NaF L-1）, low dietary iodine （0.0855 mg kg-1）, or both together in order to assess the effects of these three regimens on the thyroid function of the offspring rats. After the animal model was established, the offspring rats were bred and 10-, 20-, 30-, 60-, and 90-d-old rats were used for the experiment. The treatments for the offspring rats were the same as those of their parents. In comparison with control rats, the relative thyroid glands were changed by three regimens, but the mean values of thyroid weight in the experimental groups saw no marked difference. Serum TT3 levels were increased in all stages in the low iodine （LI） group. In the high fluoride （HiF） group, increase in TT3 levels was observed except in 20-d-old rats. Decrease in TT3 at 20- and 90-d and increase in TT3 at 30- and 60-d were found in HiF＋LI group. Serum TT4 levels first saw an increase, and then dropped in the LI and HiF＋LI group. However, an increase in TT4 was found in the HiF group. The levels of TSH in serum rocketed at d 20, and then dropped in the next stages in experimental groups. The results suggested that thyroid disorder could be induced by high flroride in drinking water, low iodine diet, or both of them. Exposure time to fluoride or low iodine diet was one of the important factors that fluoride can induce the development of thyroid dyfunction.

文摘OBJECTIVE:To observe the effects of Buzhong Yiqi granule(补中益气颗粒)on thyroid function and ovarian function in rats with experimental autoimmune thyroiditis(EAT).METHODS:EAT model was replicate by using the method of mixing and injecting porcine thyroglobulin with Freund's adjuvant and high iodine.Rats were randomly divided into normal control(NC)group,EAT model(EAT)group,selenium yeast(PC)group,low dose Buzhong Yiqi(BZYQ-L)group,medium dose Buzhong Yiqi(BZYQ-M)group and high dose Buzhong Yiqi(BZYQ-H)group.After two months of drug intervention according to dosage,enzyme-linked immunosorbent assay(ELISA)was used to measure the levels of free triiodothyronine(FT3),free thyroxine(FT4),thyroid-stimulating hormone(TSH),antithyroid peroxidase antibody(TPOAb),thyroglobulin antibody(TGAb)in peripheral blood of rats.The pathological changes of rat thyroid tissues were observed under light microscope with HE staining;ELISA was used to determine estradiol(E2),follicle-stimulating hormone(FSH),luteinizing hormone(LH),testosterone(T),antimüllerian hormone(AMH),and the pathological changes of rat ovarian tissues were observed under light microscope with hematoxylin and eosin staining.RESULTS:Compared with the NC group,BZYQ granule improved the thyroid and ovarian tissue morphology,and the levels of TPOAb,TGAb and TSH in the model group rats significantly increased(P<0.05),the thyroid tissue was severely destroyed,the levels of E2,FSH,LH,T,AMH significantly increased(P<0.05),and the ovary exhibited polycystic changes;Compared with the model group,TSH level in the BZYQ-L group rats decreased(P<0.05),FSH,T,AMH levels decreased(P<0.05),in the BZYQ-M group TPOAb,TSH levels decreased(P<0.05),FSH,LH,T,AMH levels significantly decreased(P<0.05),BZYQ-H group TPOAb,TGAb,TSH levels significantly decreased(P<0.05),FSH,LH,T,AMH levels significantly decreased(P<0.05),with the greatest improvement and significantly better than selenium yeast group(P<0.05).CONCLUSIONS:BZYQ granule could regulate the thyroid function of EAT rats,reduce thyroid antibody titers,then act on the ovarian function,regulate hormone disorders,and alleviate the pathological damage of rat's ovarian tissues.The effect of high dose Buzhong Yiqi granule is the best.
文摘With regard to brain acetylcholinesterase and acetylcholine and serum triiodothyronine(T_3) and thyroxine(T_4)profiles,a biphasic response pattern was elicited in Channa punctatus chroni- cally exposed to nonlethal doses of locally used pesticides,namely,Metacid-50 and Carbaryl. Data revealed that these xenobiotics caused significant inhibition of brain acetylcholinesterase activity and a decrease in thyroxine level accompanied by a concurrent increase in acetylcholine accumulation and T_3 level.It is surmised that Metacid-50 and Carbaryl influence both neural and hormonal functions.1989 Academic Press.Inc.
文摘Background: The thyroid status is evaluated by two clinical diagnostic tests which are thyroid ultrasonography and thyroid function tests. The objective of this research is to critically analyze the age and gender based variations of thyroid volume and thyroid hormone levels in the hospital based euthyroid subjects. Methodology: A total of 221 euthyroid subjects aged 1 - 86 years were selected to observe the normal thyroid size by ultrasonography at Department of Radiology and the thyroid function test values (FT3, FT4 and TSH) of 2413 euthyroid subjects aged (Results: The best fitted equations with significant correlation coefficients and p Conclusion: The thyroid size first increases and then decreases whereas the thyroxin level first decreases and then increases with aging. Left lobe volume is almost same for both genders and right lobe volume is higher in males. The thyroid size in menarche and menopause periods of females is larger than that of males. Such age- and gender-specific changes recommend the new refer-ence ranges for the normal thyroid functions.
文摘Objective To determine the relationship between TSH receptor gene mutations and autonomously functioning thyroid adenomas (AFTAs). Methods The thyroid samples from 14 cases of diagnosed AFTAs were analyzed, with normal thyroid specimens adjacent to the tumors as controls. The 155 base pairs DNA fragments which encompassed the third cytoplasmic loop and the sixth transmembrane segments in the TSH receptor gene exon 10 were amplified by Polymerase chain reaction (PCR) and analyzed by the single-strand conformation polymorphism (SSCP). Direct sequencing of the PCR products was performed with Prism Dye Terminator Cycle Sequencing Core Kit. Results 6 of 14 AFTA specimens displayed abnormal migration in SSCP analysis. In sequence analysis of 3 abnormally migrated samples, one base substitution at nucleotide 1957 (A to C) and two same insertion mutations of one adenosine nucleotide between nucleotide 1972 and 1973 were identified. No mutations were found in controls. Conclusion This study confirmed the presence of TSH receptor gene mutations in AFTAs; both one-point substitution mutation and one-base insertion mutation were found to be responsible for the pathogenesis of AFTAs.
文摘Objective:To assess the peripheral blood NKT cell number and function in patients with Graves disease and study their correlation with hyperthyroidism.Methods: The patients who were diagnosed with Graves disease in our hospital between May 2014 and September 2016 were selected as GD group, and 55 healthy volunteers who received physical examination in our hospital during the same period were selected as control group. Peripheral blood was collected to determine the number of CD3+CD56+NKT cells, and serum was collected to detect the contents of cytokines and thyroid function indexes.Results: Peripheral blood CD3+CD56+NKT cell number in Graves disease group was significantly lower than that in control group;serum IL-2, IFN-γ, TNF-α, IL-10 and TGF-β contents in GD group were significantly lower than those in control group and positively correlated with peripheral blood CD3+CD56+NKT cell number while IL-4, IL-5, IL-17, FT3, FT4, TPOAb, TgAb and TRAb contents were significantly higher than those in control group and negatively correlated with peripheral blood CD3+CD56+NKT cell number.Conclusion:The abnormal reduction of peripheral blood NKT cell number in patients with Graves disease can affect the balance of Th1/Th2 and Th17/Treg and increase the TRAb secretion to cause hyperthyroidism.
文摘This study was conducted to explore possible correlation between smoking habit and thyroid volume and function in Jeddah. A total of 226 volunteers i.e. 128 male and 98 female were screened at Radiology Department King Abdul-Aziz University Hospital. They were categorized as smokers and non- smokers;the number of smokers was 99 cases i.e. 48 Cigarette smokers and 51 Shisha smokers, and the non-smokers were 127 cases. The information was gathered via a questionnaire distributed at the radiology department. Ultrasonography of thyroid and thyroid function test were performed for 166 participants;and data were analyzed Using SPSS version 22 and Microsoft excel. The study was carried out based on random selection and findings revealed that most of the cases were in the age group between 20 to 30 years old, high body mass index (BMI) was 33.1 kg/m2 in persons above 60 years old and the highest percentage smokers in the age group from 20 to 30 years (40.02%). Ultrasonography of thyroid showed 96 (58%) normal cases, 46 (28%) abnormal “solid” cases and 24 (14%) abnormal “cyst” cases. A lower proportion of cigarette and shisha smokers (15.4% and 5.6% respectively) had an enlarged thyroid gland compared to no cigarettes or shisha smokers (47.9% and 47.3% respectively). The difference between these frequencies was statistically significant (Chi-square = 9.446 and 11.424, p = 0.002 and p = 0.001 for cigarette and shisha smoking respectively). Consequently, it can be concluded from this research that there are no direct significant values correlating smoking habit to thyroid volume or function. However, it is always recommended not smoke due to other well-known threats.
文摘Objective:To investigate the changing pattern of thyroid and adrenal function in postmenopa-usal women;and the relationship between hormone replacement therapy(HRT)and thyroid andadrenal function.Methods:The levels of tT_3,tT_4,fT_3,fT4,TSH and cortisol were measured in 60 postmeno-pausal women(30 cases in HRT group;30 cases in control group)before and 12 months afterHRT.Results:The serum levels of tT_3,tT_4,fT_3,fT_4,TSH and cortisol had no significant differ-ence before and 12 months after HRT in postmenopausal women.The values of them were all innormal ranges.Conclusion:Changing pattern of thyroid and adrenal function was not as significant as that ofgonads in postmenopausal women and the impact of HRT on it was not so significantly evident.
文摘Background: Pregnancy is associated with the change in thyroid function. Thyroid function is also affected by goitrogenic substances in some plant foods, like cassava. Aim: This study aims to assess thyroid function status and its association to consumption of foods containing goitrogenic substances. Methods: A cross sectional study was done on a total of 65 pregnant women attending Sawla Health Center, South Ethiopia. Serum samples were collected and analyzed for TSH, total T4 and total T3 by using ELISA kit. Data on consumption of foods containing were obtained from food frequency questionnaire. Results: The median TSH of the first, second and third trimesters, respectively are 2.57, 1.86 and 2.42 mIU/L, which are within the reference interval (0.30-6.20 mIU/L) of the test kit. The median total T4 values (9.8, 10.0 and 10.3 μg/dl in the first, second and third trimesters, respectively) were also within the reference interval (4.8-11.6 μg/dl) of the test kits. The median total T3 in the first (2.60 ng/ml) and third (2.35 ng/ml) trimesters were elevated, but it was within the reference interval (0.69-2.02 ng/ml) in the second trimester (1.92 ng/ml). Though statistically non-significant median TSH was increased in women grouped as cassava consumers and M. stenopetala consumers while median total T4 values were decreased in these groups. Conclusion: The study subjects have normal thyroid function as the median values of TSH and total T4 were within the reference interval of the test kit. Frequent consumption of cassava and Moringa stenopetala may affect thyroid function.

文摘Objective:To explore the effect of selenium supplementation on thyroid function, immune response and oxidative stress in HT patients with normal thyroid function.Methods: A total of 120 Hashimoto's thyroiditis patients with normal thyroid function admitted to our hospital from June 2016 to March 2018 were randomly divided into treatment group and control group with 60 cases in each group. The control group was given oral placebo, while the treatment group was given selenium yeast. The expression levels of thyroid function [including thyroid stimulating hormone (TSH), free triiodothyronine (FT3) and free thyroxine (FT4)], immune response [including thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TGAb), interferon-γ (IFN-γ), interleukin-4 (IL-4)] and oxidative stress [including malondialdehyde (MDA), glutathione peroxidase (GPx) and superoxide dismutase (SOD)] were observed and compared between the two groups.Results: The two groups showed significant changes in auxiliary diagnosis, immune response and oxidative stress. Before treatment, there was no significant difference in the levels between the two groups. After treatment, there was no significant difference in the above indexes between the control group and that before treatment. There was no significant difference in thyroid function related indexes between the treatment group and the control group. The levels of TPOAb, TGAb, IFN-γ and MDA in the treatment group were significantly lower than those before treatment and in the control group, while the levels of IL-4, GPx and SOD were significantly higher than those before treatment and in the control group.Conclusions: Selenium supplementation can stabilize thyroid function, reduce the level of thyroid antibody production, and improve immune response and oxidative stress response in HT patients.

The present study was designed to investigate the effects of hydro-alcoholic extract of nigella sativa L. (NS) on performance of Forced Swimming Test (FST), blood biochemical parameters related to fatigue and thyroid functions. Therefore, Blood Urea Nitrogen (BUN), Creatine Kinase (CK), Lactic Dehydrogenase (LDH), and Total Protein (TP), triiodothyronine T3, thyroxin T4 and TSH tests were investigated. Thirty five male adult mice were randomly divided into five groups: three NS-fed groups, one fluoxetine treated group and one control group. Three NS experimental groups received hydro-alcoholic extract of NS at doses of 50, 100 and 200 mg/kg orally for two weeks. Immobility time decreased in all NS groups compared with control group. Administration of NS significantly increased the concentration of T3 and T4 of the treatment groups. On the contrary, the amount of BUN, CK, LDH, TP and TSH decreased. In conclusion, black seed extract at the experimented doses showed anti-depressant, anti-fatigue and hyperthyroid effects.
文摘Objective: To investigate the effects of oxcarbazepine on immune function, thyroid function and related factors in epilepsy patients. Method: 90 patients with epilepsy who visited our hospital from January 2015 to May 2018 were selected as the observation group and 90 healthy volunteers were selected as control group. All patients in the observation group were treated with oxcarbazepine alone. T lymphocyte subsets, IgA, IgG, IgM, T3, T4, FT3, FT4, TSH, hs-CRP and Hcy in observation group were detected before treatment, 3 months after treatment and 6 months after treatment. The results were compared with those of the control group. Results: The levels of CD3+ and CD4+ in the control group were (65.25±9.51)% and (43.29±6.74)% respectively, which were higher than those in the observation group (P<0.05). The levels of CD8+, IgA and IgG in the control group were (22.40±6.41)%, (2.22±0.51) g/L, (9.99±1.28) g/L respectively, which were lower than those in the observation group (P<0.05). The levels of CD3+ and CD4+ in the observation group after 3 months and 6 months of treatment were significantly higher than those before treatment (P<0.05). The levels of CD8+, IgA and IgG in the observation group after 3 months and 6 months of treatment were significantly lower than those before treatment (P<0.05). There was no significant difference in the level of IgM between the observation group and the control group at each time point (P>0.05). The levels of thyroid hormones in the observation group before treatment and 3 months after treatment were not significantly different from those in the control group (P>0.05). The FT4 of the observation group was (14.98±1.03) pmol/L 6 months after treatment, which was significantly lower than that of the control group before treatment and 3 months after treatment (P<0.05). The levels of T3, T4, FT3 and TSH at each time point in the observation group were not significantly different from those in the control group (P>0.05). Before treatment, there was no significant difference in hs-CRP and Hcy levels between the observation group and the control group (P>0.05). The levels of hs-CRP and Hcy in the observation group were (4.82±0.67) mg/L and (13.36±1.51) umol/L respectively after 3 months of treatment. The levels of hs-CRP and Hcy in the observation group after 3 months of treatment were significantly higher than those before treatment and in the control group, and the difference was statistically significant (P<0.05). The levels of hs-CRP and Hcy in the observation group were (4.99±0.47) mg/L and (16.83±1.94) umol/L respectively after 6 months of treatment. The levels of hs-CRP and Hcy in the observation group were significantly higher than those in the control group after 3 months of treatment and before treatment (P<0.05). Conclusion: Oxcarbazepine can effectively improve the immune function of epilepsy patients, but with the prolongation of medication time, it may have adverse effects on thyroid function, hs-CRP and Hcy.
文摘Thyroid dysfunction is frequent in pregnant women and is often associated with an increased risk of adverse maternal and fetal outcome. In the present work, thyroid function of pregnant women from Benin republic was studied. Two hundred forty (240) pregnant women, without thyroid disease history, have been included in the study. A blood sample was drawn for measurement of TSH, free T3 and free T4 serum levels. From the first to the third trimester, plasma levels of free T3 and free T4 decreased when plasma levels of TSH increased. Using recommendations of the 2011 American Thyroid Association (ATA) guidelines, thyroid dysfunction was observed in 24.17% of subjects. Hypothyroidism was present in 22.50% of subjects with 19.17% of subclinical hypothyroidism, 0.83% of overt hypothyroidism and 2.50% of hypothyroxinemia and hyperthyroidism was observed in 1.67% of subjects. An increase from 15.52% to 28.07% was observed in the frequency of hypothyroidism from the first to the third trimester of pregnancy. When an upper cut-off value of 4 mU/L was used for TSH, as recommended in the 2017 ATA guidelines, prevalence of thyroid disorders was 14.58% with 12.91% of hypothyroidism but no hypothyroidism was observed in women in the first trimester of pregnancy. A rise in hypothyroidism frequency was observed when pregnant women age increased. Hypothyroidism was very common in pregnant women in Benin. To allow accurate assessment of thyroid status in pregnant women in Benin, pregnancy specific range for plasma level of TSH and thyroid hormones should be established.
