Thyroid dysfunction in Khyber Pakhtunkhwa, Pakistan

Factors responsible for the persistence of Hypothyroidism among Pakistani Women

Substantial change in climate over the years in South Asia is directly affecting the diet and health of the population. It is important to analyze the aftermath of this change and its impact on the thyroid status. In recent years, a complex interplay of the changing climate with the environmental, geographical and dietary factors has contributed to the continued prevalence of hypothyroidism in Pakistani women. To study the influence of various factors which might be aggravating hypothyroidism in the female population of Pakistan, a thorough search of literature was conducted of various databases including Google Scholar and PubMed. Google as a search engine was also explored. This included both interventional and observational studies, published in English, from the year 1950 onwards uptil June 2023. It also included WHO website and local news clips about the awareness campaigns on iodine deficiency over the past years. All studies conducted on females to diagnose hypothyroidism, with both positive and negative outcomes were included in this study. The factors contributing to hypothyroidism among the female population in Pakistan encompass the effects of climate change, both direct and indirect, topographical factor, indiscriminate use of hazardous pesticides, presence of chemical contaminants in food and water, and a lack of awareness among the public and healthcare professionals about the condition's symptoms and management.

Exploring the Effect of Metformin to Lower Thyroid-Stimulating Hormone in Euthyroid and Hypothyroid Type-2 Diabetic Patients

Introduction

Metformin is one of the safest, first-line oral hypoglycemic agents used in type-2 diabetes mellitus patients. This study aims to study the effect of metformin on thyroid-stimulating hormone (TSH) in hypothyroid and euthyroid individuals, as both these diseases have an increased prevalence and coexistence.

Method

This hospital-based study was conducted in Jinnah Allama Iqbal Institute of Diabetes and Endocrinology (JAIDE), Allama Iqbal Medical College/Jinnah Hospital Lahore, Pakistan, from October 2019 to April 2020. One hundred and sixty type-2 diabetic participants, aged 25-60 years and meeting the inclusion criteria were enrolled in the study after informed consent. They were divided into two groups, the hypothyroid group who were already on levothyroxine therapy and had a stable TSH in the normal range, and a euthyroid group who had no thyroid dysfunction. Both the groups were started on metformin therapy for the control of type-2 diabetes mellitus and followed for six months. Their blood samples for TSH and free thyroid hormone (fT4) were drawn both prior to and after the study period.

Results

Out of the 160 type-2 diabetic patients, TSH levels showed a significant reduction in the hypothyroid patients (2.33 ± 0.70, p < 0.001) with no significant changes in the euthyroid patients (3.87 ± 0.40, p = 0.206) following six months of metformin therapy. However, there was no significant difference in the fT4 levels in either of the groups.

Conclusion

Metformin has the effect of significantly lowering TSH levels in hypothyroid individuals. However, no such effect was observed in euthyroid patients.

The effect of dexamethasone on pain control after thyroid surgery: a meta-analysis of randomized controlled trials

INTRODUCTION

The effect of dexamethasone on postoperative pain after thyroid surgery remains controversial. We conduct a systematic review and meta-analysis to explore the influence of dexamethasone versus placebo on postoperative pain after thyroid surgery.

METHODS

We search PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through May 2020 for randomized controlled trials (RCTs) assessing the effect of dexamethasone versus placebo on postoperative pain after thyroid surgery. This meta-analysis is performed using the random-effect model.

RESULTS

Eight RCTs involving 734 patients are included in the meta-analysis. Overall, compared with control group for thyroid surgery, dexamethasone shows significantly reduced pain scores (SMD = - 0.82; 95% CI - 1.08 to - 0.56; P < 0.00001), number of required analgesics (OR = 0.18; 95% CI 0.11-0.31; P < 0.00001), analgesic consumption (SMD = - 0.38; 95% CI - 0.63 to - 0.13; P = 0.003), nausea and vomiting (OR = 0.38; 95% CI 0.17-0.86; P = 0.02), as well as rescue antiemetics (OR = 0.40; 95% CI 0.20-0.79; P = 0.008).

CONCLUSIONS

Perioperative dexamethasone is effective to reduce the pain, nausea and vomiting after thyroid surgery.

Morphological spectrum of endometrium with thyroid hormone profile in infertile female population of Khyber Pakhtunkhwa province of Pakistan

Objectives:

To study the morphological spectrum of endometrial changes with the thyroid hormone levels in infertile women.

Methods:

This cross sectional study was conducted at Department of Pathology, Peshawar Medical College, Health Care Centre and Madina Medical Laboratory, Peshawar from April 2013 to August 2013. Total 160 cases of infertile women were included in the study. Biopsies were taken on 22-23rd day of menstrual cycle. Statistical Analysis was performed using SPSS version 19 statistical program. Difference between endometrial findings of patients with normal thyroid profile and abnormal one were analyzed for statistical significance using Chi square test. Probability values p ≤ 0.05 were considered statistically significant.

Results:

In our study, majority infertile women were euthyroid (80%), followed by hyperthyroid (18%) and only two% to be hypothyroid. The correlation of endometrial morphology with thyroid hormones levels turned out to be insignificant. While correlating histological details of endometrial biopsy with thyroid hormone status, we found significant association of leukocytic infiltrate with thyroid hormone levels.

Conclusion:

This study shows that thyroid hormones may have role in early leukocytic infiltration into stroma, and a possibility of immune modulation by altered thyroid hormones in causing infertility.

Role of Prophylactic Dexamethasone Before Thyroidectomy in Reducing Postoperative Pain, Nausea and Vomiting

Introduction Post-operative nausea, vomiting (PONV) and pain are the most frequently encountered complains after thyroid surgery. Steroids effectively reduce pain, nausea, and inflammation, therefore prophylactic administration of steroids improve these outcomes. The aim of our study was to compare the prophylactic administration of dexamethasone with placebo in terms of PONV and pain. Patients and methods We conducted a double-blinded randomized controlled trial including 100 patients who underwent thyroid surgery from January 2017 to December 2017 in Surgical Unit-I of the Holy Family hospital, Pakistan. The outcome in terms of post-operative pain, nausea and vomiting were measured. Results The mean age of the patients was 39.62 ± 12.73 years in group A, while in group B it was 39.06 ± 13.25 years. Out of the 100 patients included in our trial, 52 (52%) patients were males and 48 (48%) patients were females. The mean value of pain in group A patients was 1.60 ± 1.26, while in group B it was 3.60 ± 1.94. A statistically significant difference was found between the study groups with regard to the pain score of the patients i.e. p-value = 0.001. The PONV was found in 28 patients from group A and 19 patients from group B and no significant improvement was seen (p-value = 0.071). Conclusion A single dose of prophylactic dexamethasone significantly reduces the mean pain score in patients undergoing thyroidectomy; however, insignificant relation was noted in terms of PONV condition.

PATTERN OF THYROID DISORDERS AMONG PATIENTS IN HAZARA DIVISION, PAKISTAN

Background: Thyroid disorders are a commonly encountered problem in hilly areas of Pakistan. The objectives of the study were to determine the frequency and distribution of thyroid disorders among patients presenting with suggestive signs & symptoms of thyroid disorders in Hazara Division, Pakistan. Material and Methods: This cross-sectional study was conducted in Departments of Medicine and Pediatrics & Neonatology, Ayub Medical College, Abbottabad, KP, Pakistan from January, 2017 to January, 2018. Exclusion criteria was patients taking medicines such as Lithium and Cordarone. Sample size was 55 selected using consecutive sampling technique. Reference values were taken as follows; serum TSH=0.4-4.0 µIU/L, serum T3=100-200 ng/dL), serum T4=5-13.5 µgm/dL. Demographic variables were sex and age. Research variables were thyroid status (euthyroid/ hyperthyroid/ hypothyroid) and levels of thyroid function tests (TFT). Categorical variables such as sex and thyroid status were calculated by frequency and percentages whereas numeric variables such as age and TFT by Mean and SD. Descriptive statistics were calculated using SPSS Version 20. Results: Out of the total 55 patients, 11 patients were males and 44 patients were females. The minimum age was 20 years, maximum age was 90 years. Mean age was 43.24 years±15.118. Out of the total 55 patients, 14 (25.5%) were euthyroid, 30 patients (54.5%) were hyperthyroid and 11 (20%) patients were hypothyroid. Out of the 14 patients that were euthyroid, seven were males and seven were females. Out of the 30 hyperthyroid patients 26 were females and only 4 were males. All 11 hypothyroid were females. Conclusions: Hyperthyroidism is more common thyroid disorder in Hazara Division specially in adult females.
