Fulltext ANCA-associated vasculitis - revisited, and its association with autoimmune thyroid disease

Lai Y, Nik Yahya NH, Ong SG

Med J Malaysia, 2014 Apr;69(2):98-100.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are a group of uncommon diseases. Given its rarity and multisystem clinical presentation which are usually serious and potentially fatal, prompt recognition and early treatment are of utmost importance. We report a case of AAV that presented with digital infarcts, cutaneous vasculitis, rapidly progressive glomerulonephritis, mononeuritis multiplex, eosinophilia and positive myeloperoxidase (MPO)-ANCA antibody. Apart from renal damage, there was complete recovery in other systems following intravenous cyclophosphamide and high-dose glucocorticoids albeit the response was delayed. This response obviates the need for second-line therapy with newer agent such as rituximab (anti-CD20 monoclonal antibody). We would also like to highlight that this is the first case of AAV that is associated with autoimmune thyroid disease to be reported from Malaysia.

We report a case of tuberculosis of the thyroid gland associated with mediastinal lymphadenitis in a 30 years-old male, who presented with dysphagia and a mid line anterior neck swelling. Fine needle aspiration was positive for acid fast bacilli. He made an uneventful recovery with antituberculous drugs. Although seldom observed, tuberculosis should be kept in mind in te differential diagnisis of nodular lesions of the thyroid.

Fulltext A supersensitive in-house enzyme-linked immunosorbent assay (ELISA) for measurement of thyroid-stimulating hormone (TSH) and its clinical applications

Goh KH, Goh ML, Thean ET, Khalid BA

Med J Malaysia, 1992 Dec;47(4):248-60.

PMID: 1303476

A supersensitive ELISA was developed for measurement of thyroid-stimulating hormone (TSH) concentrations in serum using in-house rabbit polyclonal antisera and a commercial monoclonal antibody. The assay was optimised and validated by recovery, linearity and cross-reactivity experiments and further compared to other available assays and EQAS samples. Good precision was obtained with a working assay range of 0.2 to 100 mIU/L with < 10% coefficient of variation (CV) for both intra and interassay. The assay is highly sensitive and specific with a minimum detectable limit of 0.07 mIU/L and negligible cross-reactivities against LH, FSH, HCG and other pituitary peptides. Good correlations were obtained when compared to Abbott hTSH EIA (r = 0.993; p < 0.001; n = 85) and NETRIA IRMA (r + 0.995; p < 0.001; n = 76). The normal reference range established was 0.4 to 4.0 mIU/L (n = 76). TSH levels in serum of thyrotoxic patients (n = 83) were significantly lower (0.07 to 0.20 mIU/L, p < 0.0001) and completely distinct from normal values thereby obviating the requirement of a TRH-stimulation test. Stability studies showed that coated wells can be stored at 4 degrees C for at least 2 months. This highly sensitive in-house hTSH ELISA which is cheap, stable and readily available is useful for diagnosis and management of patients with various thyroid disorders.

PMID: 7121352

The serum alpha-1 acid glycoprotein of 9 euthyroid subjects, 14 hypothyroid patients and 21 hyperthyroid patients was determined by radial immunodiffussion in agar plates. The serum alpha1 acid glycoprotein level in both the hypothyroid and hyperthyroid patients were significantly lowered when compared to the euthyroid subjects. There was no significant correlation between the alpha-1 acid glycoprotein level mid the Liothyronine resin uptake (T3 resin. uptake) and the serum total Thyroxine Iodide (T4I) level.

Endemic goitre in Malaya

Polunin I

Med J Malaya, 1951;5.

1. Observations have been quoted which mention the existence of goiter in remote inland areas of Malaya. 2. 39.5% of 618 Malays and 40.8% of 710 aborigines from inland areas were found on examination to have visible thyroid glands. A high incidence of thyroid enlargement was found in almost all areas where these observations were made, on a wide range of Geological Formations. 3. In the seaside populations studied, the low incidence of ‘visible’ thyroid glands (2/184) is typical of that of other ‘goiter free’ areas. 4. Iodine estimations have been carried out on seven water samples from rivers draining inland areas where thyroid data have been collected, and gave values of 0.2 to 0.6 parts of iodine per thousand million. The development of goiter is to be expected when the iodine content is so low. 5. High calcium content of waters cannot be important in causing goiter in Malaya. 6. The availability of dried seafoods is thought to be an important factor in goiter prevention in Malaya. Four dried marine foods contained 360 to 1,340 parts of iodine per thousand million.

Fine needle aspiration cytology of the thyroid--a review of experience in 1853 cases

Jayaram G, Razak A, Gan SK, Alhady SF

Malays J Pathol, 1999 Jun;21(1):17-27.

PMID: 10879275

1853 thyroid lesions subjected to cytological sampling (either by the fine needle aspiration or fine needle capillary sampling technique) from January 1992 to December 1997 at the University Hospital, Kuala Lumpur, were reviewed. Nodular goitre was the most common thyroid lesion needled (67.35%). Among the neoplastic lesions, follicular neoplasms predominated (64%), followed by papillary carcinoma (29.4%). In 325 cases, partial or total thyroidectomy had been done, providing material for histological review and cyto-histological correlation. Cytological diagnosis was found to have high sensitivity and specificity rates of over 75%. Besides, most non-neoplastic thyroid lesions could be diagnosed on cytology. The scope of cytology in the diagnosis of lymphomas, anaplastic and metastatic tumours rendered diagnostic biopsies (or thyroidectomy) unnecessary in these cases. Being a cost-effective technique and having the capacity to provide exact morphological diagnosis in a large variety of thyroid lesions, cytology is obviously the method of choice in the assessment of thyroid nodules.

PMID: 22589665 MyJurnal

Goitre is a slow-growing thyroid mass, rarely presenting as an emergency. However, a superimposed infection or acute intralesional bleeding can cause the mass to increase rapidly in size. We report a patient with long-standing multinodular goitre who presented with bleeding from the left thyroid mass. Despite all appropriate measures, the continuous bleeding finally stopped upon thyroidectomy.

Thyroid disorders could be broadly categorised into benign and malignant diseases. Approaches for the
management of benign and malignant thyroid disorders have been well documented including the treatment
using radioactive iodine (RAI). RAI has long been used to treat hyperthyroidism and well differentiated
thyroid cancer. Nevertheless, there are various factors that may influence the outcome of RAI treatment
including matters related to patient preparations. Thus, healthcare personnel play an important role in
assisting patients to make the necessary preparations. This article aims to give nurses and clinicians of
various specialities an insight into the overview of RAI treatment for thyroid disorders particularly in
Malaysia and further discusses the issues related to preparations of patients.

External laryngeal nerve in thyroid surgery: is the nerve stimulator necessary?

Aina EN, Hisham AN

Eur J Surg, 2001 Sep;167(9):662-5.

PMID: 11759734 DOI: 10.1080/11024150152619282

OBJECTIVE: To find out the incidence and type of external laryngeal nerves during operations on the thyroid, and to assess the role of a nerve stimulator in detecting them.
DESIGN: Prospective, non-randomised study.
SETTING: Teaching hospital, Malaysia.
SUBJECTS: 317 patients who had 447 dissections between early January 1998 and late November 1999.
MAIN OUTCOME MEASURES:
Number and type of nerves crossing the cricothyroid space, and the usefulness of the nerve stimulator in finding them.
RESULTS: The nerve stimulator was used in 206/447 dissections (46%). 392 external laryngeal nerves were seen (88%), of which 196/206 (95%) were detected with the stimulator. However, without the stimulator 196 nerves were detected out of 241 dissections (81%). The stimulator detected 47 (23%) Type I nerves (nerve > 1 cm from the upper edge of superior pole); 86 (42%) Type IIa nerves (nerve < 1 cm from the upper edge of superior pole); and 63 (31%) Type IIb nerves (nerve below upper edge of superior pole). 10 nerves were not detected. When the stimulator was not used the corresponding figures were 32 (13%), 113 (47%), and 51 (21%), and 45 nerves were not seen. If the nerve cannot be found we recommend dissection of capsule close to the medial border of the upper pole of the thyroid to avoid injury to the nerve.
CONCLUSION: Although the use of the nerve stimulator seems desirable, it confers no added advantage in finding the nerve. In the event of uncertainty about whether a structure is the nerve, the stimulator may help to confirm it. However, exposure of the cricothyroid space is most important for good exposure in searching for the external laryngeal nerve.

PMID: 1058690

A group of patients with solitary nodules of the thyroid were treated at the University of Malaya by surgery under local anaesthesia. This was done in order to expedite exploration of a potentially malignant condition. This group comprised 43 patients, and four cancers were found. The standard technique used was satisfactory from the viewpoint of both the patient and the surgeon. The pattern of this condition in a Malaysian population is documented, the technique used is described, and thyroidectomy under local aneaesthesia is discussed.

High prevalence of thyroid function test abnormalities in chronic schizophrenia

Othman SS, Abdul Kadir K, Hassan J, Hong GK, Singh BB, Raman N

Aust N Z J Psychiatry, 1994 Dec;28(4):620-4.

PMID: 7794205

The thyroid status of 249 patients with chronic schizophrenia (males = 136, females = 113) with a median age of 36 years (range: 16 to 58 years) and a median duration of hospitalisation of 10 years (range: 1 to 30 years) was assessed. Thyroid antibodies (TAb) were found in 51 patients (20%). In female patients, 32 (28%) were TAb positive compared to 13% (n = 152, p = 0.01) in healthy female blood donors. In male patients, the prevalence of TAb was 14% compared to 7% (n = 449, p = 0.01) in healthy male blood donors. Of the 183 patients who had thyroid hormone measurements, 60% had normal test, 5% had elevated TSH and 17% had low TSH. The T4, FT41 and FT31 were significantly lower in those with low or high TSH (p < 0.001) compared to those with normal TSH. Of the 143 patients with normal TSH, 33 (23%) had low T3. In conclusion, there is a spectrum of thyroid function test abnormalities in chronic schizophrenia; this may be related to an abnormality in the central regulation of the hypothalamo-pituitary thyroid axis as well as at the peripheral level. However the association between chronic schizophrenia and the presence of thyroid antibodies, and the clinical relevance of these biochemical abnormalities, are still not clear.

Fulltext Prevalence of growth and endocrine disorders in Malaysian children with transfusion-dependent thalassaemia

Tan KA, Lum SH, Yahya A, Krishnan S, Jalaludin MY, Lee WS

Singapore Med J, 2019 Jun;60(6):303-308.

PMID: 30556093 DOI: 10.11622/smedj.2018155

INTRODUCTION: Endocrine dysfunction due to iron overload secondary to frequent blood transfusions is a common complication in children with transfusion-dependent thalassaemia (TDT). We ascertained the prevalence of endocrine dysfunction in children with TDT seen in a hospital setting in Malaysia.

METHODS: We reviewed all patients with TDT who had ≥ 8 blood transfusions per year. Patients who had a history of stem cell transplantation, concurrent autoimmune diseases or were newly diagnosed to have TDT were excluded. Standard diagnostic criteria were used in the diagnosis of various endocrine dysfunctions.

RESULTS: Of the 82 patients with TDT, 65% had at least one endocrine dysfunction. Short stature was the commonest (40.2%), followed by pubertal disorders (14.6%), hypoparathyroidism (12.3%), vitamin D deficiency (10.1%), hypocortisolism (7.3%), diabetes mellitus (5.2%) and overt hypothyroidism (4.9%). Subclinical hypothyroidism and pre-diabetes mellitus were seen in 13.4% and 8.6% of the patients, respectively. For children aged < 10 years, the prevalence of both thyroid dysfunction and hypoparathyroidism was 9.1%.

CONCLUSION: Two-thirds of children with TDT experienced at least one endocrine dysfunction. Thyroid dysfunction and hypoparathyroidism may be missed if endocrine screening is only performed in children with TDT > 10 years of age. Close monitoring for endocrine dysfunction and hormonal therapy is essential to prevent long-term adverse outcomes.

Thyroid function, autoantibodies, and HLA tissue typing in children with alopecia areata

Nanda A, Alsaleh QA, Al-Hasawi F, Al-Muzairai I

Pediatr Dermatol, 2002 11 20;19(6):486-91.

PMID: 12437547

A total of 80 Kuwaiti children with alopecia areata (AA), without clinical evidence of thyroid disease, were screened for the presence of thyroid abnormalities, and 50 unrelated children with AA were tissue typed for human leukocyte antigen (HLA) class I and class II antigens. Thyroid abnormalities were detected in 14 children (17.5%). Among these, 11 children (14%) had thyroid autoantibodies. These observations highlight the significance of screening for thyroid abnormalities in children with chronic, recurrent, and/or extensive disease. The Kuwaiti children with AA were observed to have a significant association with HLA B21 (OR 18.850, 95% CI 4.404-80.677), B40 (OR 6.767, 95% CI 1.818-25.181), and HLA B12 (OR 4.833, 95% CI 1.198-19.505) antigens. These findings differed from those reported elsewhere.

Spectral sensitivity in patients with dysthyroid eye disease

Sharanjeet-Kaur, Dickinson CM, O'Donoghue E, Murray IJ

Ophthalmic Physiol Opt, 1997 May;17(3):232-8.

PMID: 9196665 DOI: 10.1111/j.1475-1313.1997.0_749.x

The majority of patients with dysthyroid eye disease have an acquired colour vision defect. However, no psychophysical investigation of selective damage to colour or flicker pathways has been carried out. In order to clarify the nature of the visual pathology, we have used a psychophysical technique (spectral sensitivity) to selectively stimulate the chromatic and achromatic mechanisms. Spectral spots of size 1 degree presented at a rate of 1 Hz on a bright 1000 td white background are detected by the chromatic mechanism but a rate of 25 Hz reveals the achromatic mechanism. Fifteen patients (28 eyes) between the ages of 50-70 years were tested. The study showed that all patients had reduced spectral sensitivity, either 1 Hz, 25 Hz or both. The patients with reduced 1 Hz or 25 Hz spectral sensitivity only had a shorter systemic and ocular duration of the condition, had no proptosis, normal intraocular pressures in primary gaze, slightly higher intraocular pressures on upgaze, normal visual field plots and FM 100-Hue error scores higher than the normal age-matched values. The patients with reduced both 1 Hz and 25 Hz spectral sensitivities had a longer systemic and ocular duration of the condition, had proptosis, normal intraocular pressures in primary position, higher intraocular pressures on upgaze and higher FM 100-Hue error scores than the age-matched normals and those in Groups 1 and 2. A total of 50% of patients in Group 3 had defective visual field plots. These data suggest that there is a damage of the large achromatic fibres and small chromatic fibres in dysthyroid eye disease. The mechanism of the damage could be one of ischaemic or mechanical or both.

Fulltext Thyroid-Modulating Activities of Olive and Its Polyphenols: A Systematic Review

Pang KL, Lumintang JN, Chin KY

Nutrients, 2021 Feb 06;13(2).

PMID: 33561976 DOI: 10.3390/nu13020529

Olive oil, which is commonly used in the Mediterranean diet, is known for its health benefits related to the reduction of the risks of cancer, coronary heart disease, hypertension, and neurodegenerative disease. These unique properties are attributed to the phytochemicals with potent antioxidant activities in olive oil. Olive leaf also harbours similar bioactive compounds. Several studies have reported the effects of olive phenolics, olive oil, and leaf extract in the modulation of thyroid activities. A systematic review of the literature was conducted to identify relevant studies on the effects of olive derivatives on thyroid function. A comprehensive search was conducted in October 2020 using the PubMed, Scopus, and Web of Science databases. Cellular, animal, and human studies reporting the effects of olive derivatives, including olive phenolics, olive oil, and leaf extracts on thyroid function were considered. The literature search found 445 articles on this topic, but only nine articles were included based on the inclusion and exclusion criteria. All included articles were animal studies involving the administration of olive oil, olive leaf extract, or olive pomace residues orally. These olive derivatives were consistently demonstrated to have thyroid-stimulating activities in euthyroid or hypothyroid animals, but their mechanisms of action are unknown. Despite the positive results, validation of the beneficial health effects of olive derivatives in the human population is lacking. In conclusion, olive derivatives, especially olive oil and leaf extract, could stimulate thyroid function. Olive pomace residue is not suitable for pharmaceutical or health supplementation purposes. Therapeutic applications of olive oil and leaf extract, especially in individuals with hypothyroidism, require further validation through human studies.
