Purpose.The association between autoimmune diseases and keratoconus (KC) has been proposed based on previous retrospective studies and case reports. The aim of our study is to investigate whether KC is associated with autoimmune thyroid disease. Methods.A comparative study was conducted on 131 adult subjects from September 2015 to May 2017 at Jordan University Hospital, Amman, Jordan. Subjects were classified into 2 groups: subjects with autoimmune thyroid disease, including Graves’ disease and Hashimoto’s thyroiditis (n=68), and a healthy group for comparison (n=63). Subjects with any other conditions known to be associated with KC were excluded. The diagnosis of KC was based on clinical and corneal topographic findings utilizing the Oculus-Pentacam machine. In addition, TSH and total T4 levels as well as thyroid peroxidase antibodies were measured in all study participants. Antithyroglobulin antibodies, thyroid stimulating immunoglobulin, thyroid ultrasound, and thyroid uptake and scan were also selectively performed in some participants.Results.This study included a total of 131 participants (101 females and 30 males), including patients and controls. In the multivariate analysis, autoimmune disease was not significantly associated with keratoconus (OR = 1.1; 95% confidence interval: 0.3, 3.8;pvalue = 0.353) after adjusting for age and gender.Conclusion.This study did not show a statistically significant association between autoimmune thyroid disease and KC.

Objective: To evaluate the prevalence of autoimmune thyroid disease (AITD) in diabetic children in south Punjab. Methods: This was an observational cross sectional study from Jan 2019 to Dec 2019 in the outpatient diabetic clinic of the department of pediatric endocrinology at Children Hospital and The Institute of Child Health Multan. A total of 161 consecutive patients of both genders with TIDM were enrolled in this study after taking informed consent. Blood samples for Thyroid functions testes including thyroid stimulating hormone (TSH), free thyroxin (fT4), Thyroid peroxidase antibody (TPO-Ab), thyroglobulin antibody (TG-Ab) and glycosylated hemoglobin (HbA1C) level were sent. Results: Among diabetic children males were 83 (51.6%). Age range was 2-15 years. Mean age and standard deviation was 9.7± 4.3. TPO-Ab was positive in 34 patients (21.1%) and TG-Ab in 27 patients (16.7%), whereas both antibodies were positive in 17 patients (10.5%). Six patients (3.7%) had evidence of subclinical hypothyroidism, 8 patients (4.9%) had overt hypothyroidism and 1 patient (0.62%) had hyperthyroidism Conclusion: The prevalence of AITD among children and adolescents with type 1 diabetes mellitus was 21.1% in our study. Hypothyroidism was more prevalent in these children compared to hyperthyroidism. All diabetic children should be screened for AITD. Thyroid functions should be checked where TPO antibody is positive.

1. The analysis of the antibody response in autoimmune thyroid disease has followed several historical trends. It was the investigation of thyroid-reactive antibody that allowed the initial characterization of the three principle thyroid autoantigens, thyroglobulin, thyroid peroxidase and the thyroid stimulating hormone receptor. 2. Analysis can be grouped under two broad areas: analysis of the physiological and pathological effects of the antibody, and analysis of the structure of the antibodies themselves. This review will focus on the latter. 3. Within recent years there has been a great increase in knowledge of thyroid-reactive antibody structure, principally through the adoption of phage display combinatorial library methodologies. While this latter technique has established some general principles for antibodies to thyroglobin and especially thyroid peroxidase, there is still a substantial gap in our knowledge of the antibody response to the thyroid stimulating hormone receptor. 4. Thyroid peroxidase antibodies have a relatively restricted V-region usage, and there is a correlation between the V-regions used and the epitope on thyroid peroxidase bound. In particular the Vκ light chain, Vκl(O12), is associated with reactivity to one epitope. 5. The purpose of this review is to bring together the latest results concerning the molecular analysis of the antibody response in autoimmune thyroid disease, to highlight areas of ignorance and conflict, and to discuss the methods adopted to circumvent the problems associated with analysis of the antibody response.

The thyroid gland is frequently associated with autoimmune disease. It produces thyroid hormones responsible for controlling cellular metabolism. The current case control study  involved ninety subjects which were assigned into two equal-numbered groups of patients and apparently healthy controls. For laboratory evaluation, five millilitres of venous blood were withdrawn from individual participants, serum were collected and  stored at –20 oC to be analysed.  Immunoassay technique was used to measure the serum level of thyroid stimulating hormone (TSH), thyroxine (T4), and triiodothyronine (T3). While ELISA technique was used for measuring the serum levels of anti-thyroid peroxidase (anti-TPO) antibodies and IL-22. The results of the current study showed that, in  the patient group, thirty eight (84.44 %) subjects were diagnosed with hypothyroidism, represented by thirty five female (77.77 %) and three male (6.67 %); furthermore, seven individuals (15.56 %) were grouped as hyperthyroid patients and represented by five females  (11.11 %) and two males (4.45 %). The results also demonstrated that the serum  TSH levels  (12.04  ± 2.76) for the patients were significantly (p< 0.05) higher than that of the control group  (1.87 ± 0.15). Whereas, T3 and T4 mean serum levels ± SE were 2.05 nmol/l ±0.14; 100.66 nmol/l ± 4.76 and 2.14 nmol/l ± 0.07; 105.37 nmol/l ± 2.92 for patient and control categories, respectively. The findings of this work showed that mean serum level (IU/ml) of anti-thyroidperoxidase antibody in patient group differed significantly (P <0.05) in comparison to control group  (represented by 259.08±59.99 and 8.71 ±1.23, respectively). No statistical difference was non-significant when comparison involved mean serum concentration levels of IL-22 for patients (157.22 ng/ml ± 24.81) and controls (157.08 ng/ml ± 24.80). In conclusion: IL-22 cannot be proposed as an essential factor participating the development and/or the progression of autoimmune thyroid disease (AITD).
