Hyperthyroidism and hypothyroidism

Thyroid disorders based on autoimmunity such as hyperthyroidism (an overactive thyroid) and hypothyroidism (an underactive thyroid) occur more frequently in people with T1DM. Both conditions are the result of autoimmune thyroiditis, which is usually missed because it causes no symptoms most of the time. In a study of 58 people enrolled in the Diabetes Control and Complications Trials published in Diabetes Care in April 2003, 18 patients had hypothyroidism and one had hyperthyroidism. When symptoms are present, they alter metabolism. Hyperthyroidism and hypothyroidism affect diabetic control, and it's important to diagnose them by doing thyroid blood tests. Treatment for hypothyroidism is replacement of thyroid hormone. Treatment of hyperthyroidism is with antithyroid drugs, radioactive iodine, or surgery. The symptoms of the more common hypothy-roidism are weight gain, slowness, dry skin, brittle nails, tiredness, and intolerance to cold. With hyperthyroidism, you get weight loss,...

Thyroid Disease in Type Children

Because type 1 diabetes is an autoimmune disease (see Chapter 2), it is not surprising that children with type 1 have other autoimmune diseases more commonly than unaffected children. The disease that is found most commonly in association with type 1 diabetes is autoimmune thyroiditis. This condition is discovered by obtaining a blood test that shows an abnormal increase in proteins in the blood called thyroid autoantibodies. In a study of 58 patients with type 1 diabetes (Diabetes Care, April 2003), 19 were found to have autoimmune thyroiditis. Autoimmune thyroiditis usually results in no symptoms, but occasionally it causes low thyroid function (hypothyroidism), and even more rarely it causes high thyroid function (hyperthyroidism). Autoimmune thyroiditis is found mostly in girls between 10 and 20 years of age. This condition is easily treated, as I explain in my book Thyroid For Dummies, 2nd Edition (Wiley). Autoimmune thyroiditis is so common in type 1 diabetes that type 1...

Screening For Thyroid Disease

People with type 1 diabetes are at higher risk for autoimmune thyroid disease most frequently the thyroid is underactive (Hashimoto's thyroiditis), but it can also sometimes be overactive (Graves' disease). Your doctor will check you for thyroid disease when you are first diagnosed with type 1 diabetes and then every one to two years. Thyroid abnormalities also increase with age, and your doctor therefore may do thyroid tests periodically even if you have type 2 diabetes.

Thyroid disease in preexisting diabetic pregnancy

During pregnancy, thyroid levels are altered by several mechanisms hCG stimulation of the TSH receptor increases the free T4 during early pregnancy, and increased thyroid-binding globulin related to estrogen stimulation later in pregnancy results in lowering of free T4. Currently, there is not a consensus regarding routine screening of TSH during pregnancy. However, 10-12 of women of reproductive age have thyroid antibodies (123). Prepregnancy screening of women with DM1 or DM2 seems warranted since early treatment may improve pregnancy outcome. For women with preexisting hypothyroidism, levothyroxine dose should be titrated every 4-6 weeks to target TSH not higher than 2.5 microunits mL preconception and in the first trimester and 3.0 microunits mL in the second and third trimesters (124).

Maternal Complications

Thyroid Disease Thyroid disease is autoimmune disease colinked with diabetes. Physiological stress from pregnancy brings out the tendency toward thyroid disease in diabetic women. Hypothyroidism may lead to gestational hypertension, which, in turn, causes increased incidence of pre-eclampsia and low birth weight (29). Controlling maternal hypothyroidism should be a concern during pregnancy. A study by Haddow and colleagues (30) indicates that hypothyroidism in the mother can impair the intellectual development of Hyperthyroidism is accompanied by an overall increase in metabolic activity. This hypermetabolic state becomes especially dangerous during pregnancy, because the mother cannot provide sufficient nourishment for both her child and herself. Fetal malnourishment resulting from hyperthyroidism increases the risk of fetal mortality and reduced birth weight (31). Hyperthyroidism also increases insulin requirements and makes blood glucose control extremely difficult. Antithyroid...

First Trimester Weeks

Coincident thyroid disease is very common in type 1 diabetes, up to 40 (26). In addition, women who are euthyroid but have thyroid autoimmunity (TAI) are at risk of developing hypothyroidism during pregnancy and should be monitored. The thyroxine dose often will require increased dosing of 30-50 by 4-6 weeks of gestation. Women who do not require increased amounts of replacement in the first trimester may still require increased dosing later in gestation, and therefore a serum TSH should be measured every 30-40 days. The TSH goal is less than 2.5 mLU L if hypothyroidism is diagnosed prior to pregnancy in the first trimester and 3.0 mLU L in the second and third trimesters (27).

Effect Of Cooccurring Diseases On Glycemic Control And Treatment Of Diabetes

Hyperthyroidism leads to insulin resistance and increased insulin doses to control hyperglycemia. This should be taken into account when thyrostatic therapy is commenced for a diabetic patient, and the insulin doses should be adequately reduced to avoid hypoglycemia when euthyroidism is reached. On the other hand, hypothyroidism in a diabetic patient is often diagnosed after an increased frequency of hypoglycemia. Treatment of hypothyroidism will lead to an increased demand for insulin. Hypocorti-solism can cause hypoglycemia both in diabetic and nondiabetic subjects. Patients with type 1 diabetes are particularly sensitive to changes in cortisone levels and usually need hydrocortisone substitution divided in at least three daily doses or supplementation with a longer-acting preparation (e.g., prednisone) to avoid nocturnal hypoglycemia. Untreated CD can lead to malabsorption and hypoglycemia. Correction of hypothyroidism may provoke an Addisonian crisis in patients with subclinical...

Risk Factors For Obesity

Various medical genetic causes of obesity must also be considered. Endocrine conditions associated with weight gain include hypothyroidism, Cushing's syndrome, hypogonadism in the male, polycystic ovary syndrome (PCOS) in the female and growth hormone deficiency (42). Rare genetic causes of obesity include Prader-Willi syndrome, Bardet-Biedl syndrome and Cohen's syndrome. Diabetes can be an obvious consequence of the severe obesity associated with such syndromes.

Acquired Hypothalamic Alterations

Lesions of the ventromedial area of the hypothalamus (VMH) may result form inflammatory processes such as encephalitis, arachnoiditis, tuberculosis, or trauma, or malignancy (Frohlich syndrome) (305,306). Children with hypothalamic obesity may present with a history of foraging and stealing foods. They have a voracious appetite and may display frequent tantrums if food is denied. In children, craniopharyngioma is the most common CNS tumor that leads to hypothalamic and pituitary dysfunction (307). Hypothalamic obesity is often coupled with other hypothalamic-pituitary disturbances, which may exacerbate the obesity (e.g., growth hormone deficiency or hypothyroidism), but the obesity resists treatment with hormonal replacement (308,309). It is believed that hypothalamic injury leads to alterations in the appetite center, which can cause hyperphagia and obesity (310). However, there is increasing evidence that the hyperinsulinemia seen in this disorder plays a role in the development of...

Human Single Gene Mutations

Believed that excessive weight gain in these children is caused by disturbance of hypothalamic appetite center(s), which leads to increased food intake. Pseudo-hypoparathyroidism (Type 1A) (PHP) is also associated with obesity and short stature and is characterized by short fourth metacarpal, short thick neck, rounded facies, mental retardation, and hypocalcemia (240). It is commonly inherited as an autosomal dominant trait and may be accompanied by hypothyroidism and gonadal failure. The gene is located in chromosome 20q13.2. These patients present a germline loss of function mutations in the alpha subunit of the ubiquitously expressed G protein that couples many hormone receptors to the adenylate cyclase second messenger system. The hypothalamic GS protein-coupled melanocortin 4 (MC4) receptor in the hypothalamus, which mediates the effects of leptin on inhibition of satiety as described below. PHP patients present genetic mutations in GS alpha, which result in severe obesity and...

Pathogenesis And Treatment Of The Macrovascular Complications Of Type Diabetes

Unlike patients with type 2 diabetes who have, if anything, a superabundance of CAD risk factors, patients with type 1 diabetes have a scarcity of traditional CAD risk factors. Lipid profiles are generally normal or even quite good with high levels of high-density lipoprotein (HDL) cholesterol when glucose is well controlled. Triglycerides and low-density lipoprotein (LDL) cholesterol are rarely elevated unless the diabetes is poorly controlled (13). Alterations of LDL particle size distribution are common in type 2 diabetes, in which small dense phenotype B LDL particles of increased atherogenic potential predominate as the consequence of insulin resistance (14). This shift in LDL particle size is rarely seen in type 1 diabetes. However, as in type 2 diabetes, glycation of apolipoproteins with an increased potential for lipid oxidation is noted in type 1 diabetes. This undoubtedly contributes in part to the excess atherosclerosis of poorly controlled type 1 diabetes (15). Oxidized...

Investigating the pathogenesis of problematic hypoglycaemia

It is important to avoid carrying out hypoglycaemia studies on people with ischaemic heart disease, epilepsy, hypertension, untreated hypothyroidism, hypoadrenalism or unstable diabetic retinopathy. It is crucial not to carry out studies on women of childbearing age if radioisotopes or potentially teratogenic or fetotoxic drugs are to be used, because of the potential risk to any future fetus.

Which medicines are used in the treatment of diabetic dyslipidaemia

In rare cases it can even lead to rhabdomyolysis and renal damage. The frequency of myositis is exceptionally small (roughly 0.05-0.1 percent), but increases mainly in diabetics with nephropathy (proteinuria), hypothyroidism and liver disease. The appearance of myalgias without myositis presents, in the various studies, at a rate of 2-11 percent. The preventive measurement of serum CPK is not recommended, because it does not predict the future appearance of myositis (a measurement at the beginning of treatment, however, is nonetheless recommended for potential future comparison). The patient should be informed about the symptoms of myositis and be told to stop the medicine in the event of compatible symptoms, to drink lots of fluids and contact their treating physician for measurement of CPK. The incidence of clinically important myopathy is increased in the event of coadministration of a statin with other medicines that inhibit the cytochrome P450-3A4, mainly...

The Vitamin D Metabolism Gene CYPB

The cytochrome P450, subfamily XXVIIB, polypeptide 1 gene (CYP27B1) encodes 25-hydroxy-vitamin D3-1-a-hydroxylase, which is expressed in the renal proximal tubule and catalyzes metabolic activation of 25-hydroxyvitamin D3 into 1a, 25-dihydroxyvitamin D3 1-a,25-(OH)2 D3 , the active form of vitamin D (118). As a key enzyme in vitamin D metabolism, mutations of this gene have been shown to cause type 1 vitamin D-dependent rickets (119-122). Two polymorphisms, a promoter region SNP rs10877012 and an intronic SNP rs4646536, were reported to be associated with DM1 by a study of 187 DM1 German families (123). Recently, the DM1 association was confirmed by a large-scale study (124). Besides DM1, Lopez et al. showed also that the CYP27B1 promoter SNP is also associated with Addison's disease, Hashimoto's thyroiditis and Graves' disease (125). The role

Testing For Autoimmune Diseases

I mentioned in Chapter 3 that people with type 1 diabetes are at risk for other autoimmune diseases, especially thyroid disease and celiac disease. When your child is diagnosed with type 1 diabetes, he should also be screened for autoimmune thyroid disease. His doctor will do these thyroid tests at intervals or if there is a problem with your child's growth, because low thyroid hormone levels can slow down growth.

Handling the Physical and Emotional Consequences of Type Diabetes

Not only does T1DM have short- and long-term physical consequences, but as an autoimmune disease, T1DM also is associated with other autoimmune diseases such as celiac disease, an inflammation of the gastrointestinal tract thyroid disease and skin diseases. Chapter 5 explains the importance of checking for those diseases and correcting them, if present.

Orthostatic Hypotension

The first step in the management of orthostatic hypotension is the discontinuation, where possible, of long-acting hypotensive agents that may be contributing to the problem. Occasionally, the patient can be switched to a shorter-acting agent (captopril, e.g.) and the timing of the dose altered in order to minimize daytime orthostatic changes. Other non-neuropathic etiologies such as volume depletion, adrenal insufficiency, anemia, and hypothyroidism should be addressed. Typical initial approaches to the problem include elevating the head of the bed by 30 during the night, instructing the patient to make changes in posture slowly stand-in-stages and use of body stockings (which have to be at least waist high). The latter often do not meet with much success, however, because of the fact that much of the fluid pooling is not in the lower extremities, but in the splanchnic circulation. Plasma volume expanders such as a high-salt diet or fludrocortisone (up to 0.4 mg d), which also...

Diagnosis And Ancillary Investigations

Diabetic Foot Drawing

Routine laboratory investigations are recommended to exclude possible reversible causes of cognitive impairment. The practice parameter of the American Academy of Neurology (AAN) states that vitamin B12 deficiency and hypothyroidism should be ruled out, as these are comorbidities that are likely to appear in the elderly and in patients with suspected dementia in particular (26). Unless the patient has some specific risk factor or evidence of prior syphilitic infection, screening for neurosyphilis is not recommended (26). Additionally, blood sedimentation rate, complete blood cell count, electrolytes, glucose, renal and liver function tests can be tested to evaluate possible comorbidities at first evaluation.

The interaction of insulin resistance and Bcell function

It is possible that nonautoimmune and autoimmune destruction of (-cells could coexist, but the current classification considers two subtypes. In type 1a there is evidence suggesting an autoimmune origin of (-cell destruction, mostly determined by the presence of circulating antibodies against islet cells insulin antibodies in the absence of exposure to exogenous insulin or antibodies to glutamic acid decarboxylase, and or islet cell-associated phosphatase. This autoimmune entity also is associated with certain HLAs. Patients with type 1a are also more likely to have other concomitant autoimmune disorders, such as autoimmune thyroiditis, Addison's disease, and celiac disease.

Do not take Lugols iodine if you know you are allergic to iodine It could be fatal

Naturally, one would not leave such medicine within the reach of children. Also, one would not use anything medicinal, including Lugol's unless there were a need, like cancer, AIDS, or bowel disease. When the gas and bloating problem has stopped, stop using Lugol's. If one or two doses of Lugol's cures the problem, stop. Store it in a perfectly secure place. In the past, 2 3 of a teaspoon (60 drops) of Lugol's was the standard dose of iodine given to persons with thyroid disease. Six drops is small by comparison.

Growth Puberty And Diabetes Insulin Deficiency And Resistance

Another important but easily overlooked cause of adolescent growth failure or delayed puberty in adolescents with diabetes is hypothyroidism resulting from Hashimoto's thyroiditis. Although only a small proportion of affected children, mostly girls, develop hypothyroidism, up to 10 of children and adolescents with diabetes develop a goiter and antithyroid antibodies (23). Similarly, celiac disease affects up to 5 of diabetic children and adolescents, often only presenting with growth failure or

Epidemiology Of Dyslipidemia In Type Diabetes

Dyslipidemia is common in patients with type 2 diabetes it is present at the time of diagnosis, and even in the pre-diabetic phase. It persists despite usual hypoglycemic therapy and its expression will be affected by genetic and lifestyle characteristics, such as gender, obesity, exercise levels, diet, alcohol intake, poor glycemic control, smoking, hypothyroidism, as well as renal and hepatic function. It is also affected by concomitant drugs and the presence of primary dyslipidemia, such as familial combined hyperlipidemia.

Counseling and Preconception Care Recommendations to Reduce Maternal and Fetal Risks of Preexisting Diabetes What Are

Thyroid Disease Does My Thyroid Disease Affect My Pregnancy Thyroid disease is a common problem for women with both DM1 and DM2. All women with diabetes should be screened with a TSH for thyroid abnormalities in the preconception period. Women with hypothyroidism on stable replacement hormone doses should be advised to increase their thyroid hormone dose by 30 once pregnancy is confirmed (62). It is beyond the scope of this chapter to discuss the management of hyper or hypothyroidism in detail.

Thyroid

Obese individuals, but serum concentrations of triio-dothyronine (T3) are elevated, likely due to increased peripheral conversion of T4 to T3 (338). Furthermore, TSH response to TRH stimulation has been reported to be variable (65,338). The blunted TSH response to TRH stimulation in obesity is believed to be due to increased somatostatinonergic tone because soma-tostatin inhibition by pyridostigmine pretreatment significantly enhances the TSH response in obese adults but not in obese children (339). Hypothyroid-ism is not a common cause of obesity. However it has long been shown that excessive weight gain, secondary to an underactive thyroid gland, is due to a combination of decreased metabolic rate and enhanced fluid retention (340). In children, hypothyr-oidism is associated with poor linear growth. Therefore, a normally growing overweight child is not likely to be hypothyroid.

Postpartum

Chronic autoimmune or lymphocytic thyroiditis (or TPO antibodies) is present in 18-25 of patients with type 1 diabetes (26). If there is already known hypothyroidism, levothyroxine doses are reduced to the preconception dose. Women with type 1 diabetes who have TPO antibodies without hypothyroidism are at increased risk of postpartum thyroiditis (25 ) (26).

Clinical Picture

Autoimmune thyroid disease, total 66 Hashimoto's thyroiditis 33 Diabetes appears to be the most prevalent of the single-component diseases (see Table 3). Graves' and Hashimoto's diseases are equally common, and the joint prevalence of thyroid disease exceeds the prevalence of diabetes. Diabetes was significantly more common in males and thyroid disease in females. The mean age of manifestation was 27 yr for diabetes and between 36 and 40 yr for the other components (see Fig. 4). Diabetes was also the first component to appear in 48 of the individual patients, followed by 19 for Graves' disease, 17 for Hashimoto's disease, and 15 for adrenocortical insufficiency. Only diabetes showed a gender difference with respect to the order of appearance it was the first in 65 of the males, in contrast to 43 of the females. Of combinations of the component diseases, diabetes with thyroid disease was the most common, occurring in 33 . The second, diabetes with adrenal insufficiency, made up 15 ,...

Immunology

Most of the autoimmune endocrine disorders appear initially as infiltration of the gland by lymphocytes and macrophages. This may lead to destruction and atrophy of the gland with deficiency of its hormone. Sometimes, it halts or even reverses at a stage of relative hypofunction. This has been documented for thyroiditis (5) and adrenalitis (6), and may be true for insulitis (7,8). The destructive process is presumed to be T-cell mediated. Commonly, antibodies to certain antigens of the gland appear in blood, most frequently antibodies against intracellular enzymes. The role of such autoantibodies Exceptions to this uncertainty of antibody role are some antibodies against membrane receptors, like the a-chain of the acetylcholine receptor in myasthenia gravis and the thyrotropin receptor in AITD. Antibodies to thyrotropin receptor can act as either agonists causing Graves' hyperthyroidism or blockers causing hypothyroidism. The net effect depends on their relative activities. Other...

Genetic Syndromes

Watery bloody diarrhea Failure to thrive Type 1 diabetes mellitus Hypothyroidism Eczema are thought to be responsible for this syndrome, which is found in greatest frequency among Iranian Jews, Sardinians, and Finns (55). Although T1DM is relatively uncommon in APS Typel (approximately 1 of affected probands), a publication on a series of Finnish patients with APECED reported a 12-fold higher prevalence of diabetes compared to the general population (56). The association between diabetes and both autoimmune adrenal insufficiency and thyroiditis is considerably greater in patients with APS type 2, also known as Schmidt syndrome (57), or Carpenter syndrome, so called when all the three conditions are present (58). Autoimmune diabetes is present in 20 to 50 of subjects with the APS type 2, and usually presents at an earlier age than either Addison's disease or thyroid disorders (59,60). As with classical type 1A diabetes, and similar to what is seen in other isolated autoimmune...

Pathophysiology

Diabetes mellitus type 1 may be sporadic or associated with other autoimmune diseases within patients or within families. The latter has been classified as autoimmune polyglandular syndrome type II (APS-II). APS-II is a polygenic disorder with a female preponderance which typically occurs between the ages of 20 and 40 years (9). In clinical practice, anti-thyroxine peroxidase (TPO) positive hypothyroidism is the most frequent concomitant autoimmune disease in type 1 diabetic patients, therefore all type 1 diabetic patients should annually be screened for the presence of anti-TPO antibodies. Other frequently associated disorders are atrophic gastritis leading to vitamin B12 deficiency (pernicious anemia) and vitiligo. Rare disorders in APS-II are presented in Table 2. Autoimmune hypothyroidism

Thyroid functions

Too much thyroid hormone leads to insulin resistance, making diabetes worse. Too little thyroid hormone increases insulin sensitivity, so people with low thyroid function have reduced levels of blood glucose. All children born in the United States are tested at birth with a thyroid-stimulating hormone (TSH) blood test because low thyroid function during development of the brain may lead to reduced intelligence. The TSH is the most sensitive test of thyroid function. Treatment for low thyroid function (hypothyroidism) is with replacement thyroid hormone. Treatment for increased thyroid function (hyperthyroidism) is with antithyroid drugs, radioactive iodine, or surgery. See my book Thyroid For Dummies (Wiley) for much more on this topic.

The CTLA Locus

An A-G transition at position 49 (+49G > A, rs231775), which encodes an Ala Thr substitution in the signal peptide, had been associated with DM1 in a European population (65). Subsequently, this DM1 association was replicated in different populations (66-70). However, controversy remains that some studies did not replicate the DM1 association. The mechanism remains undetermined. Kouti et al. found that the predisposing +49G allele is associated with reduced T-cell proliferation (64), while Maurer et al. found that the predisposing +49G allele is associated with greater proliferative response of T cells (63). Besides DM1, the CTLA4 gene variation is also associated with RA (26), SLE (71), Graves' disease, and autoimmune hypothyroidism (72). In patients with DM1 and the CTLA4 gene variation, female gender is a known risk factor for the development of antithyroid antibodies (73). The Ala Thr substitution from +49G > A maps to the signal peptide and does not exist in the mature...

Tamara C Takoudes MD

Labor and delivery is a unique time for the gravid woman with diabetes, as there are specific challenges with changing insulin requirements related to labor, mode of delivery, and type of diabetes. This chapter will give a brief overview of the use of insulin during pregnancy, intrapartum as well as postpartum, but please refer to Chap. 17 for a more complete discussion. Postpartum concerns in women with diabetes include an increased risk of endometritis and wound infection, postpartum thyroiditis, decreased insulin requirements, and contraception challenges.

Interferons

Interferons (IFNs) comprise a group of related proteins whose effects include antiviral activity, growth regulatory properties, inhibition of angiogenesis, regulation of cell differentiation, enhancement of major histocompatibility complex antigen expression and a wide variety of immunomodulatory activities. They were originally classified according to their source and have subsequently been renamed Alpha-IFN (formerly known as leukocyte IFN), beta-IFN (formerly known as fibroblast IFN) and gamma-IFN (formerly known as immune IFN). Use of IFN therapy especially IFN-alpha in the treatment of hepatitis-C is common. They are commonly used in the management of hepatitis-C. There have been some reports of it causing IGT or DM. In some cases the presence of immunological data suggests DM1 (149-152) while in others the need for insulin is only temporary (153). This diabetogenic effect is perhaps unsurprising since (i) IFN is a cytokine involved in the immunopathology that leads to P-cell...

Tolerance Mechanisms

The MHC-antigen complex is an essential component of the thymic selection (or deletion) of lymphocytes and their eventual maturation into CD4+ or CD8+ T cells. Both the expression of coreceptors, CD4 and CD8, and costimulatory molecules such as CD80 86 and CD40L, appear to be important in the selection of regulatory T cells and the deletion of potentially autoreactive lymphocytes. Another important mechanism in the determination of central tolerance is the expression and presentation of autoantigens in the thymic cortex and medulla. Animal studies have clearly shown that specialized cells, called medullary thymic epithelial cells (mTECs) and dendritic cells (46) are able to transcribe and express proteins usually found in peripheral tissues, such as insulin, thyroglobulin, and myelin basic protein (47-49), which have been associated with autoimmune T1DM, thyroiditis and multiple sclerosis, respectively. The qualitative and quantitative expression of these proteins by mTECs appear to,...

Other Specific Types

Markers of immune destruction, including ICA, and or IAA, autoantibodies to GAD and IICA 512 are present in 85-90 of individuals when fasting hyperglycemia is initially detected, and often many years before (28). The peak incidence of this form of Type 1 diabetes occurs in childhood and adolescence but the onset may occur at any age ranging from childhood to the ninth decade of life (29). Patients are rarely obese when they present with this type of diabetes. However, the presence of obesity is not incompatible with the diagnosis. Other autoimmune disorders such as Grave's disease, Hashimoto's thyroiditis and Addison's disease may be associated with Type 1 diabetes mellitus (30).

Problem

Ir n I The parent of a 4-year-old boy with type 1 diabetes consults you wanting to know if there U H is anything he can do to prevent a future child developing the condition. He already has an 8-year-old daughter with diabetes and there is a strong family history of autoimmune thyroid disease on both his and his wife's side of the family. They are contemplating having a third child.

Checking the TSH

Because there is a higher incidence of thyroid disease among people with diabetes and because thyroid disease is often confused with other conditions, a screening test called the thyroid stimulating hormone level is done at the time that diabetes is diagnosed and every five years thereafter if it is normal. Too much thyroid hormone leads to insulin resistance, making diabetes worse than before. Too little thyroid hormone increases insulin sensitivity so people with low thyroid function have reduced levels of blood glucose. Much more about thyroid disease and its treatment can be found in my book Thyroid For Dummies, 2nd Edition.

Alstrom Syndrome

This syndrome was first described in 1959, when two of Alstrom's original patients died from renal failure (86). The characteristic features of this syndrome appear to be pigmentary retinal degeneration, sensorineural hearing loss, childhood obesity, non-insulin-dependent diabetes mellitus, hyperlipidaemia, and chronic nephropathy. Features occasionally observed include acanthosis nigricans, hypogonadism, hypothyroidism, alopecia, short stature, and cardiomyopathy. A large kindred including eight affected patients has been described (87). Hyperinsulinemia and hypertriglyceridemia with normal cholesterol levels were observed in most affected individuals tested. Non-insulin-dependent diabetes and growth retardation appeared to be age-related manifestations that occurred postadolescence. Younger affected children were not overtly hyperglycaemic and were normal or above average height for age.
