Cardiac failure is an uncommon complication of juvenile hyperthyroidism. We describe an adolescent boy with Graves' disease who developed manifestations of heart failure while on antithyroid medications. There was no evidence of any underlying cardiac disease. He had paradoxical euthyroid hormone profile which rose to hyperthyroid range when the manifestations of the cardiac failure subsided. The case highlights several unusual features of Graves' disease.

We describe a 48-year-old man with thyroid storm presenting with heart failure. He presented severely impaired left ventricular wall motion and a marked increase in the liver enzymes. He developed disseminated intravascular coagulation on day 2. Due to elevated serum thyroid hormone level, anti-thyroid hormone receptor antibody positivity, and his clinical symptoms, he was diagnosed as thyroid storm due to untreated Graves' disease. His condition did not improve even after 6 days of conventional therapy including steroids. After therapeutic plasma exchange was carried out, his thyroid hormone level decreased markedly. Consequently, his condition recovered gradually, and he was discharged at day 43.

Over the past few decades, there has been an increase in the number of reports about newly recognized (atypical or unusual) manifestations of Graves' disease (GD), that are related to various body systems. One of these manifestations is sometimes the main presenting feature of GD. Some of the atypical manifestations are specifically related to GD, while others are also similarly seen in patients with other forms of hyperthyroidism. Lack of knowledge of the association between these findings and GD may lead to delay in diagnosis, misdiagnosis, or unnecessary investigations. The atypical clinical presentations of GD include anemia, vomiting, jaundice, and right heart failure. There is one type of anemia that is not explained by any of the known etiological factors and responds well to hyperthyroidism treatment. This type of anemia resembles anemia of chronic disease and may be termed GD anemia. Other forms of anemia that are associated with GD include pernicious anemia, iron deficiency anemia of celiac disease, and autoimmune hemolytic anemia. Vomiting has been reported as a presenting feature of Graves' disease. Some cases had the typical findings of hyperthyroidism initially masked, and the vomiting did not improve until hyperthyroidism has been detected and treated. Hyperthyroidism may present with jaundice, and on the other hand, deep jaundice may develop with the onset of overt hyperthyroidism in previously compensated chronic liver disease patients. Pulmonary hypertension is reported to be associated with GD and to respond to its treatment. GD-related pulmonary hypertension may be so severe to produce isolated right-sided heart failure that is occasionally found as the presenting manifestation of GD.

Hyperthyroidism has many characteristic manifestations of various organ systems. Cardiovascular effects are frequent in these patients. A less known complication of hyperthyroidism is reversible right-sided heart failure and pulmonary hypertension. In the patient presented, the symptoms of atrial fibrillation and right-sided heart failure were the first manifestations of hyperthyroidism. Doppler echocardiography confirmed pulmonary hypertension. Other secondary reasons for pulmonary hypertension were excluded. Graves' disease was the only reasonable choice. The treatment of hyperthyroidism resulted in conversion in sinus rhythm, withdrawal of symptoms and signs of right-sided heart failure, and normalization of pulmonary artery pressure.

Jaundice related to thyrotoxicosis and not as an effect of antithyroid drugs is a rare complication that usually occurs in the presence of heart failure (HF) or hepatitis. We report a case of a 54-year-old white woman with hyperthyroidism caused by Graves's disease and jaundice despite methimazole suspension. Bilirubin fluctuated at high values, between 30.0 and 52.3 mg/dL, transaminases were slightly increased, on admission ALT = 46 U/L and AST = 87 U/L; coagulation indices and serum proteins were on the lower limit of the normal range with PT 68% and albumin = 2.5 g/dL. Serology for hepatitis was negative. After the first radioiodine therapy (RT), bilirubin reached its maximum, which coincided with the worst period of HF exacerbation. Bilirubin normalized 4 weeks after the second RT, with the stabilization of HF and normalization of thyroid hormones. We discuss the possible etiologies of severe jaundice in hyperthyroid patients, as well as the difficult anticoagulant therapy with warfarin.

Graves' disease is the most common cause of hyperthyroidism in the developed world. It is caused by an immune defect in genetically susceptible individuals in whom the production of unique antibodies results in thyroid hormone excess and glandular hyperplasia. When unrecognized, Graves' disease impacts negatively on quality of life and poses serious risks of psychosis, tachyarrhythmia and cardiac failure. Beyond the thyroid, Graves' disease has diverse soft-tissue effects that reflect its systemic autoimmune nature. Thyroid eye disease is the most common of these manifestations and is important to recognise given its risk to vision and potential to deteriorate in response to radioactive iodine ablation. In this review we discuss the investigation and management of Graves' disease, the recent controversy regarding the hepatotoxicity of propylthiouracil and the emergence of novel small-molecule thyroid-stimulating hormone (TSH) receptor ligands as potential targets in the treatment of Graves' disease.

Graves' disease (GD) is the most common cause of hyperthyroidism in children. This review gives an overview and update of management of GD. Antithyroid drugs (ATD) are recommended as the initial treatment, but the major problem is the high relapse rate (30%) as remission is achieved after a first course of ATD. More prolonged medical treatment may increase the remission rate up to 50%. Alternative treatments, such as radioactive iodine or thyroidectomy, are considered in cases of relapse, lack of compliance, or ATD toxicity. Therefore, clinicians have sought prognostic indicators of remission. Relapse risk decreases with longer duration of the first course of ATD treatment, highlighting the positive impact of a long period of primary ATD treatment on outcome. The identification of other predictive factors such as severe biochemical hyperthyroidism at diagnosis, young age, and absence of other autoimmune conditions has made it possible to stratify patients according to the risk of relapse after ATD treatment, leading to improvement in patient management by facilitating the identification of patients requiring long-term ATD or early alternative therapy. Neonatal autoimmune hyperthyroidism is generally transient, occurring in only about 2% of the offspring of mothers with GD. Cardiac insufficiency, intrauterine growth retardation, craniostenosis, microcephaly and psychomotor disabilities are the major risks in these infants and highlight the importance of thyroid hormone receptor antibody determination throughout pregnancy in women with GD, as well as highlighting the need for early diagnosis and treatment of hyperthyroidism.

A young female presented with evidence of right-sided heart failure and was subsequently found to have significant pulmonary artery hypertension (PAH). Because of her normal left ventricular function and pulmonary capillary wedge pressure, the most probable site of etiology seemed to be the pulmonary vasculature. All the common possible secondary causes of PAH were ruled out, but during the investigations, she was found to have elevated thyroid function tests compatible with the diagnosis of Grave's disease. The treatment of Grave's disease, initially by medications and subsequently by radioiodine therapy, was associated with a significant reduction in the pulmonary artery systolic pressure. The purpose of this case report is to highlight one of the unusual and underdiagnosed presentations of Grave's disease.

We present a case of acute heart failure as the first manifestation of Graves' disease. It illustrates some of its cardiovascular complications, particularly atrial fibrillation, pulmonary hypertension and heart failure. This case report highlights the importance of considering hyperthyroidism as a cause of idiopathic pulmonary hypertension, and demonstrates the potential reversibility of its complications.

A 38-year-old woman on medical therapy for Basedow disease and hypertension with a history of recent heart failure became pregnant. At the 13th week of gestation, her echocardiography showed pulmonary hypertension with 63 mmHg of estimated systolic pulmonary arterial pressure. At the 26th week of gestation, she was admitted to our hospital with dyspnea and uncontrolled hypertension. After medical treatments, elective caesarean section was scheduled at the 30th week of gestation. While monitoring continuously arterial blood pressure and central venous pressure, continuous infusion of prostaglandin E1 was initiated. After epidural anesthesia had been established, surgical procedure was safely performed. The patient was discharged 9 days after surgery, and her estimated systolic pulmonary arterial pressure dropped to 35 mmHg on echocardiography 2 months after the operation. We speculate that pregnancy induced her severe pulmonary hypertension.
