RÉSUMÉ

Background: Polycystic ovarian syndrome (PCOS), a heterogeneous endocrine disorder is most common in women of the reproductive age group. Thyroid disorders and PCOS are two of the most common endocrine disorders in women. Although the etiopathogenesis of hypothyroidism and PCOS is completely different, these two disorders have many common features. An increase in ovarian volume and cystic changes in ovaries have been reported in primary hypothyroidism. The aim of this study was to find the correlation of thyroid-stimulating hormone (TSH) level in obese and non-obese women, who were diagnosed to have PCOS.Methods: The data of 161 women who visited the institution for diagnosis and management of PCOS were included in the study. Demographic data like age, height and weight of the women at the time of diagnosis of PCOS were collected and subjected to analysis.Results: The results showed that 15% obese PCOS women had high TSH level and 7% non- obese PCOS had high TSH level.Conclusions: The result of the study suggests that higher level of TSH seen in obese PCOS women than non -obese PCOS women.

RÉSUMÉ

This study was conducted to determine if there is a relationship between vitiligo and ABO blood groups, the Rhesus (Rh) factor, thyroid stimulating hormone (TSH) and vitamin D. For vitiligo analysis, two hundred subjects participated in this study, 100 vitiligo patients and 100 control cases (without vitiligo). ABO blood grouping and Rh typing were tested by a slide method. TSH testing involved 80 vitiligo patients and 80 controls (without vitiligo) and the hormone was analyzed by separating the serum in a centrifuge for two minutes and the results were obtained by Beckman fully automatic analyzer. For vitamin D, 50 vitiligo patients and 50 healthy people (without vitiligo) were included. The data on vitamin D were obtained from private laboratory services. Statistical analysis was performed using IBM SPSS version 26. P< 0.05), while no statistically significant difference in TSH serum levels between vitiligo cases and controls, was found (p-value > 0.05). Furthermore, despite showing that subjects with blood group O are more susceptible to vitiligo as compared to other groups, there was no significant association of vitiligo with ABO blood groups (p-value > 0.05). Similarly, the incidence of Rh positive and Rh negative was not statistically different between the two groups (p-value > 0.05). This study showed that vitiligo patients are often vitamin D deficient. This study highlights the need to evaluate vitamin D status in vitiligo patients to improve the level of skin pigment loss. It remains unknown whether vitamin D deficiency causes vitiligo. However, a collection of larger sample sizes of different ethnicities should be required to achieve a precise conclusion.

RÉSUMÉ

Background: The study's objective was to evaluate and compare total serum protein, serum albumin, and thyroid hormones in children with PEM (protein-energy malnutrition) and healthy controls.Methods: In this cross-sectional study, 100 children with PEM served as cases, while an equal number of age and gender-matched healthy children served as controls. 4 ml of venous blood were taken (3 ml in a plain vial and 1 ml in an EDTA vial) and immediately submitted for further investigation. SPSS software (version 25) was used to analyze the data. A p value of ?0.05 was considered statistically significant.Results: PEM children have lower serum total protein, albumin level, total T3 (TT3), and total T4 (TT4) levels compared to healthy controls (p<0.0001). Mean TSH levels in cases and controls were nearly similar. There was no significant difference between serum TSH concentrations in PEM children and the controls. Grade I PEM had the highest mean total protein, serum albumin, T3, and T4 levels, followed by grades II, III, and IV. When mean total protein, serum albumin, T3, and T4 levels of each grade of PEM were compared to controls, mean total protein, serum albumin, T3, and T4 levels were substantially lower in each grade of PEM (p<0.0001).Conclusions: PEM children have low serum total protein and albumin levels. This is probably due to decreased oral intake of proteins and reduced biosynthesis. Serum TT3 and TT4 levels are lower in children with PEM than in healthy controls, which is most likely due to reduction in circulating plasma proteins.

RÉSUMÉ

Background: Due to the very high complications of neonatal hypothyroidism in the country, neonatal screening program is performed for timely diagnosis and treatment of neonates. The aim of this study to investigate the relationship between infant hypothyroidism and maternal thyroid disease. Methods: This cross-sectional study was done on 195 neonates with a diagnosis of hypothyroidism. Necessary data were collected by a checklist and then analyzed by statistical methods in statistical package for the social sciences (SPSS) version 21 by statistical methods. Results: Of all mothers, 21.0% had a history of thyroid disease. There was no statistically significant relationship between maternal age and infant thyroid stimulating hormone (TSH). There was no significant relationship between the history of maternal hypothyroidism and maternal hypothyroidism (during experiments) with the amount of TSH in the newborn. There was a direct and significant relationship between maternal TSH level and maternal free T4. But there was no statistically significant relationship between infant TSH level and maternal TSH level and free T4. There was no significant difference in neonatal TSH levels with maternal anti-TPO status. There was no significant relationship between the history of maternal diabetes and the history of maternal hypertension with neonatal TSH. There was no significant difference in neonatal TSH levels by maternal thyroid status. Conclusions: In the present study, no significant relationship was found between the incidence of neonatal hypothyroidism and the presence of thyroid disease in mothers. The existence of different genetic and environmental factors and the significant impact of each of these factors can justify this result.

RÉSUMÉ

Background: Premature babies, particularly those with very low birth weight (VLBW), are at a higher risk of developing congenital hypothyroidism. The inadequate development of the hypothalamic-pituitary axis in preterm infants contributes to the higher prevalence of this condition in this population. However, the optimal screening and treatment protocols for congenital hypothyroidism in preterm newborns remain unclear.Methods: This was a hospital-based observational study conducted over a period of 18 months. The study included 150 preterm babies born at the Sri Adichunchanagiri hospital and research centre. Non-probability sampling was used to select the study subjects. Data on demographic and clinical factors were collected from mothers and newborns. Blood samples were collected at day 3 of life to estimate thyroid-stimulating hormone levels. Correlations between TSH levels and various parameters were analyzed using statistical methods.Results: The study found that the prevalence of congenital hypothyroidism in preterm newborns was 2%. The mean TSH level at day 3 was 7.56 mIU/L, and 9.3% of cases had TSH levels above 20 mIU/l. Significant associations were found between high TSH levels and primiparity, vaginal delivery, and maternal gestational diabetes mellitus. There was an inverse correlation between TSH levels and gestational age, birth weight, and Apgar scores at 1 and 5 minutes.Conclusions: The study revealed a prevalence of congenital hypothyroidism of 2% in preterm newborns. Risk factors such as primiparity, vaginal delivery, and maternal GDM were associated with high TSH levels. These findings highlight the importance of screening and early detection of congenital hypothyroidism in premature babies to improve outcomes.

RÉSUMÉ

Background: Thyroid dysfunction is one of the most common endocrine disorders affecting women of reproductive age group. There is a debate among obstetricians about universal versus targeted screening for hypothyroidism during pregnancy. Therefore, we conducted this study with aim to highlight the need for universal screening of pregnant women for hypothyroidism.Methods: This was prospective analytical study involving 200 pregnant women conducted in a tertiary care hospital in Mumbai from January 2018 to December 2019. Thyroid-stimulating hormone (TSH) was done as a screening test. Estimation of free T3 (FT3) and free T4 (FT4) are advised if TSH was found abnormal. Patients were followed up throughout the pregnancy and postpartum up to 6 weeks. Study parameters were assessed in both mother and neonate and statistical analysis was done.Results: Pregnancy induced hypertension (PIH) was observed in 13% of study population. Premature labour was observed in 11% of study population. Recurrent abortion was observed in 7% of study population. Postpartum haemorrhage (PPH) was observed in 4% of study population. Anaemia was observed in 69% of study population. Neonatal intensive care unit (NICU) admission was observed in 17% of study population. Neonatal hypo/ hyperthyroidism was observed in 3% of study population.Conclusions: Pregnant females should routinely be screened for thyroid functions to detect hypothyroidism and be given adequate treatment to prevent maternal and foetal complications. Adequate treatment and regular follow up will improve the maternal and foetal outcomes.

RÉSUMÉ

Background: Chronic liver disease (CLD) is a continuous process of inflammation, destruction, and regeneration of liver parenchyma, which leads to fibrosis and cirrhosis. Liver plays an essential physiological role in thyroid hormone activation and inactivation, transport, and metabolism, as well as the synthesis of thyroid binding globulin. A complex relationship exists between thyroid and liver in health and disease. Methods: 103 patients of CLD were included in this study from December 2020 to September 2022. They were classified as per child Pugh scoring after clinical assessment and investigations. Thyroid function profile was measured for all the patients. Results: Among 103 patients, 8 (7.76%) patients were having overt hypothyroidism and 28 (27.18%) patients had subclinical hypothyroidism, while 67 (65.04%) patients had normal thyroid profile levels. There was significant correlation between CTP class and hypothyroidism status of patient (p value <0.001) with 25 (56.81%) patients of CTP class C having subclinical hypothyroidism, while 3 (7.5%) patients of CTP class B had subclinical hypothyroidism and none patient of CTP class A had subclinical hypothyroidism. Conclusions: Our study found that there was increased prevalence of subclinical hypothyroidism in CLD patients which increased with severity of CLD as assessed with CTP class.

RÉSUMÉ

Background: The association between anemia and hypothyroidism has been recognized, although the prevalence of anemia in hypothyroid patients varies widely between studies. The main objectives were to study the prevalence, type, etiology of anemia in primary hypothyroidism and to correlate severity of anemia with severity of hypothyroidism. Methods: This research was conducted as a case-control study. Patients with newly diagnosed overt primary hypothyroidism and euthyroid controls totaling 170 in total were included in the study. The morphological subtypes of anemia and the causes of each were investigated. There was a correlation between the severity of anemia and that of hypothyroidism. Results: Anemia was highly prevalent among cases, as it was present in 110 (64.7%) of patients with hypothyroidism and in 60 (35.3%) of patients who did not have hypothyroidism in the control group. In cases, 100 (58.8%) of serum samples tested positive for anti-TPO, while just 20 (11.8%) of control samples did so. In these cases, with elevated TSH, the anemia was severe. Conclusions: Our study concluded that a statistically significant high anaemia prevalence was found among the patients with primary hypothyroidism. In comparison to the controls, it was shown that cases had a significantly higher incidence of certain types of, as well as anti-TPO positive and iron insufficiency. The TSH level and hemoglobin level were shown to have a statistically significant inverse association with one another.

RÉSUMÉ

Background: When the thyroid gland does not produce and release enough thyroid hormone into your circulation, it is known as hypothyroidism. Your metabolism becomes slower as a result. Hypothyroidism, also known as an underactive thyroid, can make you feel exhausted, put-on weight, and have trouble with cold weather. In utero, throughout infancy, during youth, or even during maturity, it may begin to develop. The frequency of unanticipated overt hypothyroidism varies from 1 to 18 cases per thousand persons when accompanied by biochemical and clinical symptoms of hypothyroidism. The aim of the study was to observe the various clinical presentations of hypothyroidism Methods: This cross-sectional observational case-based study was conducted at the institute of nuclear medicine, Dhaka medical college hospital, Dhaka, Bangladesh. The study duration was 6 months, from January 2005 to July 2005. A total of 50 patients attended at the study place during the study period who were biochemically hypothyroid were included in the study. Results: The age range of the patients was 13 months to 54 years with a mean age of 29.5 years in this series. The majority of the patients were between 20 to 49 years of age. Female comprises 80.0% in comparison to 20.0% of male cases of hypothyroidism. Spontaneous primary (idiopathic) hypothyroidism (90.0%), post-radioiodine therapy, and post-ablative hypothyroidism were the most important causes of hypothyroidism in this series. Most typical symptoms and signs of hypothyroidism were found in this study. The most common symptoms were generalized weakness, lethargy, slowness of activities, impairment of memory, loss of scalp hair, somnolence, dry skin, puffiness of the face, constipation, weight gain, hoarseness of voice, swelling of the body, decreased sweating and paraesthesia. Cases of idiopathic hypothyroidism and other types had similar symptoms. The mean duration of symptoms before medical consultation was 2.9 years. Dry and coarse skin topped the list of physical findings and was present in 60.0% of the cases. Other findings in order of frequency include goiter (56.0%), puffiness of the face (38.0%), cold and thick skin (44.0%), thick tongue (24.0%), peripheral edema (24.0%), Anemia (20.0%), pallor of the face (12.0%), bradycardia (08.0%), thick lips (4.0%), ascites (2.0%) and pericardial effusion (2.0%). Conclusions: Although in the present series a limited number of patients were included, it encompassed varieties of cases. Moreover, an attempt was made to evaluate the common presentation, age incidence, sex distribution, and laboratory status of hypothyroidism in our country, giving more emphasis on clinical findings.

RÉSUMÉ

Background:Thyroid diseases are among the commonest endocrine disorders. It effects growth, embryonic development, tissue differentiation, maturation, metabolism, increases chronotropic and inotropic action of heart. The aim was to study gonadal dysfunction in womenwith thyroid disease; to study levels of FSH, LH, prolactin, estrogen and testosterone in hypothyroid and hyperthyroid.Methods:All participants fulfilling the inclusion criteria were interviewed as per proforma and medical details were recorded in proforma sheet and patients were subjected to necessary blood investigations.Results:Among 80 study subjects, majority were in the age group 26-35 years (60.1%) and majority had overt hypothyroid disease (72.5%). Symptoms of hypothyroid subjects mainly were fatigue, weight gain, hair loss, oligomenorrhea. Hyperthyroid subjects had fatigue, palpitations, oligomenorrhea, polymenorrhea. Prolactin had positive correlation with TSH in hypothyroid subjects, their LH, FSH levels were normal and sex steroid levels were low. In contrary, majority of the hyperthyroid subjects had normal prolactin and FSH, high LH and high sex steroid levels.Conclusions:The study demonstrated that thyroid disease in women causes menstrual abnormalities due to altered gonadotropinpatterns which in turn alter ovarian hormone pattern. Hypothyroidism is associated with hyperprolactinemia leading to anovulation and abnormal menstrual cycle. Hyperthyroidism is associated with increased levels of LH, estrogen and testosterone with normal levels of PRL and FSH. Screening, identifying and correcting thyroid disease should be undertaken to prevent infertility as early as possible.

RÉSUMÉ

Alopecia areata is an autoimmune disease that causes hair loss. It is characterized by patchy hair loss that affects the scalp and other areas of the head, as well as the eyelashes, beard, and complete body hair. Alopecia areata manifests as a circular patch of hair loss that may progress to baldness of the entire scalp (Alopecia areata totalis) or loss of full body hair (Alopecia areata universals). The disease's etiopathogenesis is unknown, however autoimmunity appears to play a signi?cant role. Thyroid problems are frequently linked to AA, the most common of which is autoimmune Thyroid disorders. Aim: The goal of our research is to see if Alopecia Areata (AA) is linked to thyroid hormones (T3, T4, and TSH) and to evaluate the T3, T4, and TSH levels. Material and Methods: The present study included 150 A.A patients(cases) and 150 controls attended to Department of Dermatology in collaboration with Department of Biochemistry, LNMC & J.K Hospital, Bhopal. The levels of T3, T4 and TSH was estimated by ELISA. Result: The present study shows statistically signi?cant differences between patients and controls regarding Thyroid Hormones levels of TSH, T3 and T4. Conclusions: The ?ndings imply an association between Alopecia Areata and Thyroid function issues. Thyroid function abnormalities should be checked in all patients with alopecia areata, regardless of their clinical condition

RÉSUMÉ

Background: Thyroid disorders are among the common endocrine disorders in pregnant woman after diabetes mellitus. Pregnancy is a stress test of maternal thyroid function. Several changes are observed in maternal thyroid function during pregnancy and failure to adapt to these physiological changes results in thyroid dysfunction. Subclinical hypothyroidism occurs in 10% of all pregnancies. Hypothyroidism has adverse effects on mother and fetus like anemia, pre eclampsia, preterm delivery, low birth weight and mental retardation of neonate. Decreased availability of thyroid hormones also impair neurological and intellectual development of the fetus. The relevance of this study is to document the association of hypothyroidism and its adverse effects on mother and fetus. Materials and methods: This prospective observational study was carried out during the period January 2020 to December 2020 (12 months) at Government General Hospital (GGH), Rangaraya Medical College, Kakinada, Andhra Pradesh, India. Subjects of this study were 170 antenatal women in third trimester with singleton pregnancy admitted in the obstetric ward, and informed consent was obtained. Women were chosen irrespective of age, parity, residence and socioeconomic status. Women with multiple pregnancy, a known case of thyroid disorder, or any pre-existing medical disorder were excluded. Routine hematological parameters and estimation of T3, T4 and TSH was conducted. Results: In this study out of 170 cases, anemia was seen in-15.29%, pre eclampsia in-11.77%, GDM in-4.11%, Oligohydramnios with IUGR in-5.88%, preterm labor in-3.53%, LSCS in-35.29% and IUFD in-0.59% of case and low birth weight (8.24%), Hyperbilirubinemia (3.53%) and NICU admissions (11.76%). Conclusion: This Study concluded that hypothyroidism in pregnancy leads to preeclampsia, preterm labour, increases caesarean delivery, low birth weight and hyperbilirubinemia in neonates. Henceeffective treatment of hypothyroidism ensures safe pregnancy with minimal maternal and foetal complications.

Objective:Pretibial myxedema (PTM) is a localized myxedema characterized by excessive dermal hya-luronan (HA) deposition and elevated serum TSH receptor antibody (TRAb). In this study, we investigated the effects of TRAb and its subtypes, stimulating antibody [TSAb (M22)] and inhibitory antibody[TBAb (K1-70)], on the synthesis of hyaluronic acid produced by PTM primary dermal fibroblasts.Methods:Normal and PTM dermal fibroblasts were isolated and stimulated with M22, K1-70, and IgG from patients respectively. HA concentration in the supernatant before and after stimulation was tested by ELISA. The protein level and phosphorylation variation of CEMIP, HAS2 and PI3K-AKT pathway were detected by Western blot.Results:IgG from patients (TRAb 8.4 IU/L) significantly stimulated the extracellular accumulation of HA in PTM primary fibroblasts. Similarly, both M22 and K1-70 also upregulated HA level in the supernatant, though K1-70 seemed much more effecitve. After treatment with IgG, M22, and K1-70, the expression of HAS2 increased and the expression of CEMIP decreased; meanwhile, p-PI3K and p-AkT increased. Among them, further study on K1-70, promoting HA production by regulating PI3K-AkT signal pathway could be inhibited by PI3K inhibitor (LY294002).Conclusion:TSAb (M22) and TBAb (K1-70), especially TBAb, increase HAS2 and inhibit CEMIP expression by activating PI3-AKT signaling pathway in PTM fibroblasts, leading to increased extracellular HA level.

Objective@#To evaluate the status of euthyroidism achieved among Thai patients with post-ablative hypothyroidism and to examine the difference between various weight-based daily levothyroxine (LT4) replacement regimens in these patients.@*Methodology@#We conducted a retrospective review of Thai patients with Graves’ disease (GD) who developed hypothyroidism following radioactive iodine treatment from 2016 to 2020 at Theptarin hospital. Daily LT4 dose was calculated based on actual body weight (ABW), ideal body weight (IBW), and estimated lean body mass (LBM).@*Results@#We reviewed a total of 271 patient records. Of these, 81.2% were females with a mean age of 40.8±11.7 years, LT4 intake duration of 27.1±14.6 months, and LT4 dose/kg ABW of 1.4±0.5 μg/kg/day. At the final follow-up, 62.4% of patients achieved thyroid-stimulating hormone (TSH) levels within the reference interval, 15.5% had TSH levels over, and 22.1% had TSH levels under the reference range. Obese patients required a lower daily LT4 dose relative to ABW and higher daily LT4 dose relative to IBW to attain euthyroidism (ABW 1.1±0.4 μg/kg/day and IBW 2.0±0.8 μg/kg/day). Estimated daily LT4 dose based on LBM showed a constant dosage of 2.0 μg/kg/day in all BMI categories.@*Conclusions@#Suboptimum LT4 replacement therapy was found in almost half of hypothyroid patients with GD treated with radioactive iodine. Estimated LBM was a better indicator for dosing calculation in these patients compared with ABW and IBW.

RÉSUMÉ

Objective To discuss the epidemiological characteristics of the dynamic changes of serum FT3, FT4, and TSH levels in patients with hemorrhagic stroke under the age of 45, and to discuss the prognostic evaluation effects and influencing factors of these indicators. Methods From January 2017 to January 2020, 227 patients with multicenter hemorrhagic stroke in our hospital were selected for analysis. Collect and analyze prognosis (death, rebleeding, no adverse prognosis) at baseline and 12 months of follow-up; monitor serum FT3, FT4, and TSH levels during treatment at the same time during follow-up, 7 days after treatment, and 14 days after treatment. Observe the trend characteristics of dynamic changes. The assay method is enzyme-linked immunosorbent assay. At the end of the follow-up, the subjects were divided into three groups: death, rebleeding, and no adverse prognosis according to the prognostic outcome of the 12-month short-term follow-up. The epidemiological characteristics of patients with different prognosis and the dynamic change trend of FT3, FT4 and TSH in the same serum were compared. The interconnectedness. Results There were no statistically significant differences in gender and age between the three groups (P>0.05), but the differences in hypertension, hyperglycemia, and hyperlipidemia were statistically significant (P0.05). The FT4 level of the case group was significantly higher than that of the control group at all times (P0.05). The TSH level of the case group was significantly higher than that of the control group at all times (P0.05). With the decrease of the patient's age, the serum FT3 level has a gradually increasing trend, and the serum FT4, TSH level, mortality and rebleeding rate have a gradually decreasing trend (P<0.05). Conclusion The continuous decrease of FT3 level and the continuous increase of FT4 and TSH levels are potentially associated with the poor prognosis of patients with hemorrhagic stroke, which is worthy of clinical attention.

RÉSUMÉ

ABSTRACT Objective: Thyroid functions in preterm newborns may be altered in the first week of life. Hypothyroxinemia has been commonly reported in these babies, which could be due to the immaturity of the hypothalamic pituitary thyroid axis or acute illness. It could have a long-term impact on the developing brain of these babies. We conducted this study to estimate the incidence of transient hypothyroxinemia of prematurity (THOP) and to determine its risk factors. Materials and methods: We analyzed thyroid stimulating hormone (TSH) and free T4 levels of 64 preterm neonates admitted in the neonatal intensive care unit. TSH and free T4 levels were measured in the first week and then at 14-21 days of life to estimate the incidence of THOP and determine its risk factors. We also estimated the incidence of congenital hypothyroidism (CH) and delayed TSH elevation in CH. Risk analysis was conducted using simple and multiple logistic regression, and numerical data was compared using the Mann Whitney U test and t test. Results: THOP was seen in 25% of the preterm babies. Caesarean delivery, presence of one or more morbidities, mechanical ventilation, birth weight ≥ 1,500 g, and gestational age ≥ 32 weeks were identified as risk factors for THOP based on simple logistic regression. In multiple regression, mechanical ventilation and gestational age ≥ 32 weeks were significantly associated with THOP. CH was seen in 2 (3.1%) babies, and 1 of these cases had delayed TSH elevation.

RÉSUMÉ

Resumen El hipotiroidismo es el cuadro clínico resultante de la disminución en la producción de hormonas tiroideas. Objetivo. Fue caracterizar el hipotiroidismo en pacientes que acudieron al laboratorio clínico del Centro de Especialidades IESS de la Libertad, durante el período enero 2018 - enero 2020 mediante la medición de niveles de FT3, FT4, TSH. Materiales y Métodos. Se realizó un estudio de tipo descriptivo, de diseño documental. El universo constituye 2451 pacientes con sospecha de enfermedad tiroidea que acudieron al servicio de laboratorio del Centro de Especialidades IESS, La Libertad durante el período enero 2018 a enero 2020. Se procedió a revisar archivos de historial de resultados de los pacientes atendidos en el laboratorio. Resultados. 617 pacientes cumplen criterios de hipotiroidismo primario lo cual representa una prevalencia del 25,2%. El hipotiroidismo subclínico, constituye el 70,8%, el hipotiroidismo clínico representa el 29,2%, estos fueron más frecuentes en mujeres. En cuanto al grupo etario el hipotiroidismo subclínico se presenta con mayor frecuencia en el grupo de adultos 44,9 % y en adultos jóvenes 24,8 %. En referencia a las comorbilidades asociadas; tanto en el hipotiroidismo clínico y subclínico las más representativas en orden de frecuencia son: hipertensión arterial (35%), dislipidemia (25,8%) y diabetes mellitus (14,1%). Conclusiones . Existe una alta prevalencia de hipotiroidismo primario, los hombres se clasifican mayoritariamente con hipotiroidismo clínico, las mujeres tienen mayor frecuencia de hipotiroidismo subclínico. La presencia de comorbilidades como hipertensión arterial, dislipidemias y diabetes mellitus tipo II están presentes en los pacientes hipotiroideos estudiados.


Abstract Hypothyroidism is the clinical picture resulting from decreased thyroid hormone production. Objective. Was to characterize hypothyroidism in patients attending the clinical laboratory of the Centro de Especialidades IESS de la Libertad, during the period January 2018 - January 2020 by measuring levels of FT3, FT4, TSH. Materials and Methods . A descriptive study of documentary design was performed. The universe constituted 2451 patients with suspected thyroid disease who attended the laboratory service of the Centro de Especialidades IESS, La Libertad during the period January 2018 to January 2020. We proceeded to review the results history files of the patients attended in the laboratory. Results. 617 patients met criteria for primary hypothyroidism which represents a prevalence of 25.2%. Subclinical hypothyroidism constitutes 70.8%, clinical hypothyroidism represents 29.2%, these were more frequent in women. Regarding the age group, subclinical hypothyroidism was more frequent in adults 44.9% and in young adults 24.8%. In reference to the associated comorbidities; both in clinical and subclinical hypothyroidism the most representative in order of frequency are: arterial hypertension (35%), dyslipidemia (25.8%) and diabetes mellitus (14.1%). Conclusions. There is a high prevalence of primary hypothyroidism, men are mostly classified with clinical hypothyroidism, women have a higher frequency of subclinical hypothyroidism. The presence of comorbidities such as arterial hypertension, dyslipidemias and type II diabetes mellitus are present in the hypothyroid patients studied.


Resumo O hipotireoidismo é o quadro clínico resultante da diminuição da produção de hormônios da tireóide. Objetivo. Caracterizar o hipotireoidismo em pacientes que freqüentam o laboratório clínico do Centro de Especialidades IESS de la Libertad, durante o período de janeiro de 2018 a janeiro de 2020, medindo os níveis de FT3, FT4, TSH. Materiais e métodos. Foi realizado um estudo descritivo do projeto documental. O universo consistia de 2451 pacientes com suspeita de doença da tireóide que compareceram ao serviço laboratorial do Centro de Especialidades IESS, La Libertad, durante o período de janeiro de 2018 a janeiro de 2020. Procedemos à revisão dos arquivos de histórico dos resultados dos pacientes atendidos no laboratório. Resultados. 617 pacientes preencheram os critérios para o hipotireoidismo primário, o que representa uma prevalência de 25,2%. O hipotireoidismo subclínico constituía 70,8%, o hipotireoidismo clínico 29,2%, e estes eram mais frequentes nas mulheres. Em termos de faixa etária, o hipotireoidismo subclínico foi mais freqüente em adultos (44,9%) e em adultos jovens (24,8%). Em referência às co-morbidades associadas; tanto no hipotireoidismo clínico como no subclínico, as mais representativas em ordem de frequência são: hipertensão arterial (35%), dislipidemia (25,8%) e diabetes mellitus (14,1%). Conclusões . Há uma alta prevalência de hipotireoidismo primário, os homens são na maioria classificados com hipotireoidismo clínico, as mulheres têm uma maior frequência de hipotireoidismo subclínico. A presença de co-morbidades como hipertensão, dislipidemia e diabetes mellitus tipo II estão presentes nos pacientes hipotireóides estudados.
