Abstract
We describe a case of acute liver injury and migratory arthralgia in a patient receiving bicalutamide treatment for prostate cancer. A 67-year-old male with metastatic prostate cancer presented with a 6-day history of migratory arthralgia. He had been undergoing treatment with bicalutamide for 4 months; 3 weeks prior to symptom appearance the bicalutamide dose had been increased. He had no other symptoms. Liver tests and inflammatory markers were markedly elevated. Serology for hepatitis viruses A, B, and C, CMV, and EBV and autoimmune causes were all negative, and an ultrasound of the upper abdomen was normal. There was no history of blood transfusion, intravenous drug abuse, or alcohol abuse. Due to the suspicion of a drug-induced symptomatology, bicalutamide was discontinued and the patient started on 30 mg prednisolone daily. Three weeks later he was symptom free and after 6 weeks his liver tests were almost normal. The Roussel Uclaf Causality Assessment Method (RUCAM) suggested a high probability of liver injury. Bicalutamide has very rarely been reported as a causative agent for liver injury and to our knowledge never for migratory polyarthralgia. The migratory polyarthralgia was attributed to bicalutamide due to the absence of other etiological factors and the disappearance of symptoms after discontinuation of the drug. To our knowledge, this is the first published case report of migratory arthralgia and concomitant liver injury attributed to bicalutamide.

Abstract
The purpose of this case report and review of the literature is to provide an exploration of the clinical symptoms, diagnosis, prevention, and management of propylthiouracil (PTU)-associated vasculitis in the intensive care setting. A PubMed search of the available literature was conducted using the MeSH search terms "propylthiouracil" and "vasculitis." The literature search returned 121 articles. Twenty-five were excluded because they were not in English. Fifty-nine case reports or case studies describing PTU-associated vasculitis were included. Data extracted from each case study included patient age, sex, autoimmune markers, laboratory tests, length of time on PTU, treatment for vasculitis, and patient outcomes. The authors reviewed 128 cases of PTU-associated vasculitis. The majority were women (8.8:1 F:M ratio), and the most common presenting symptoms were rash (51.6%), fever (46.9%), and arthralgia (43.8%). In addition to discontinuing PTU, the most common treatment was steroids (71.9%). Eight patients (6.3%) progressed to end-stage renal disease; two (1.6%) required intubation for respiratory failure; and five (3.9%) died of various organ systems failure related to vasculitis development. A high index of suspicion for vasculitis should be maintained, especially when presented with skin manifestations in the presence of PTU therapy. Screening with myeloperoxidase-antinuclear cytoplasmic antibodies is most sensitive. Positive screening should prompt a thorough clinical investigation. In cases of severe skin manifestations, the focus should be on aggressive wound care. Our case report is unique, not only in the size and extent of cutaneous involvement, but also as the first description of mortality secondary to cutaneous manifestations.

Abstract
Background Adverse reactions associated to anti-thyroid drugs include fever, rash, arthralgia, agranulocytosis and hepatitis that are thought to be hypersensitivity reactions. Five cases of pleural effusion associated to thionamides have also been reported, two with propylthiouracil and three with carbimazole. Case presentation We report here a case of a 75-year-old man admitted because of unilateral pleural effusion. The patient had a recent diagnosis of hyperthyroidism and 6 days after starting methimazole complained of pleuritic chest pain. He had elevated C-reactive protein and erythrocyte sedimentation rate and normal white blood cell count and liver enzymes. Chest radiography showed a moderate right pleural effusion and the ultrasound revealed a loculated effusion that was shown to be an eosinophilic exudate. Conclusions The temporal relationship between methimazole intake and the development of pleural effusion combined with the extensive exclusion of alternative causes, namely infectious, neoplastic and primary auto-immune diseases, led to the diagnosis of hypersensitivity reaction to methimazole. The thionamide was stopped and corticosteroid was started with complete resolution of the pleural effusion in 3 months. Awareness of this rare adverse reaction of anti-thyroid drugs is important and methimazole can be added to the list of possible etiologies of drug-induced eosinophilic pleural effusion.

Abstract
Propylthiouracil (PTU)-associated vasculitis is a potentially life-threatening disease with a recent increase in the reported cases in the medical literature. This increase may suggest that some earlier cases have been unrecognized or assigned to an alternative nosology category. Although the skin can be the only organ affected by PTU-associated vasculitis, there are many reports with multiple-system involvement. Classically, the symptoms appear under a tetrad of fever, sore throat, arthralgia, and skin lesions. Cutaneous lesions in reported cases of PTU vasculitis have most commonly consisted of retiform acral, purpuric plaques, or nodules. We report a case of perinuclear antineutrophil cytoplasmic antibody-associated vasculitis developed during treatment with PTU for Grave's disease.

Abstract
Background: Nitrobenzene is a carcinogen, which induces—among others—thyroid tumors. Melatonin is an effective antioxidant, whereas some antioxidative effects of propylthiouracil (PTU; an antithyroid medication used for the treatment of thyrotoxicosis) were also found. The aim of the study was to compare protective effects of melatonin and PTU against lipid peroxidation in homogenates of porcine thyroids, incubated in the presence of nitrobenzene. Methods: Homogenates of porcine thyroids were incubated for 30 min in the presence of nitrobenzene (0.001, 0.01, 0.1, 0.25, 0.5, 1.0, 2.5, 5.0, 7.5, and 10.0 mM). The level of lipid peroxidation products (malondialdehyde + 4-hydroxyalkenals) was measured spectrophotometrically. Nitrobenzene (7.5 and 10.0 mM) increased lipid peroxidation in the homogenates of porcine thyroids. Subsequently, homogenates of porcine thyroids were incubated for 30 min in the presence of nitrobenzene (7.5 mM) plus one of the antioxidants: melatonin (0.000001, 0.00001, 0.0001, 0.001, 0.01, 0.1, 0.25, 0.5, 1.0, 2.5, 5.0, and 7.5 mM) or PTU (0.01, 0.1, 0.25, 0.5, 1.0, 2.5, 5.0, and 7.5 mM). Results: Lipid peroxidation caused by nitrobenzene was effectively prevented by melatonin, with the lowest effective concentration of 0.0001 mM, being only two orders of magnitude higher than physiological blood concentration in humans. At the same time, PTU revealed protective effects only in the highest used concentration (7.5 mM), which is practically never reached during pharmacological treatment in patients with thyrotoxicosis. Conclusions: Melatonin can serve as an effective agent in protection against nitrobenzene-induced lipid peroxidation in porcine thyroid.

Abstract
Several studies have shown the relation between Graves' disease and stenosis/occlusion of intracranial arteries. To our knowledge, only 31 cases, including our case, of concurrent Graves' disease and moyamoya syndrome or intracranial arterial stenosis/occlusion have been described. The patients were predominantly women, and their ages ranged from 10 to 54 years (mean, 29.3 years). Transient ischemic attacks and cerebral infarction were the common symptoms in these patients. Except one previous case and the present case, all cases showed thyrotoxicity when the cerebral ischemic event occurred. Among the 29 cases, in which the treatment regimen was known, antithyroid therapy was administered in 25 cases, and surgical treatment for cerebral vessel diseases was performed in 11 cases. Most of the patients eventually recovered from the neurological symptoms after medical and/or surgical treatment; one of the patients died, and one patient's condition worsened. Although the mechanism underlying intracranial arterial occlusion or stenosis in patients with Graves' disease has not been elucidated, several hypotheses have been described. Thyroid hormones may augment vascular sensitivity to the sympathetic nervous system and induce pathological changes in the arterial walls. An immune-mediated mechanism may play a role in the pathogenesis of these diseases. Atherosclerosis may be associated with these disorders. Vasculitis induced by antithyroid drugs may cause changes in the intracranial arteries. Finally, the possibility of a mere coincidence of Graves' disease and these vascular changes should also be considered. Cerebrovascular hemodynamic changes induced by thyrotoxicosis were considered to be responsible for the cerebral ischemic events. Excessive thyroid hormone production is considered to increase the cerebral metabolism and oxygen consumption. In addition, thyrotoxicosis-induced hypercoagulability may influence ischemic events. Therefore, the possibility of thyrotoxicosis should be considered when patients with Graves' disease show exacerbation of cerebral ischemic symptoms at follow-up. The necessity of surgery in addition to antithyroid therapy might be dependent on the mechanisms of the vascular changes and symptoms. If hyperthyroidism is associated with vascular changes and symptoms, antithyroid therapy may be adequate. However, if immune-mediated mechanisms or coincidences are considered to be associated with vascular changes and symptoms, like our case, surgical procedures might be needed.

Abstract
Propylthiouracil (PTU) is a common and effective clinical medicine for the treatment of hyperthyroidism. Our previous study demonstrated that short-term treatment with PTU inhibits progesterone production in rat granulosa cells. However, our present results indicate that a 16-h treatment with PTU was able to stimulate pregnenolone production in rat granulosa cells, although progesterone production was diminished by PTU through inhibition of 3β-hydroxysteroid dehydrogenase. Notably, we found that PTU treatment enhanced the conversion of cholesterol into pregnenolone, whereas the protein level of the cytochrome P450 side-chain cleavage enzyme (P450scc, which is the enzyme responding to this conversion) was not affected. Interestingly, the levels of steroidogenic acute regulatory protein (StAR) in both total cell lysate and the mitochondrial fraction were significantly increased by PTU treatment. Furthermore, the binding of steroidogenic factor-1 (SF-1) to the StAR promoter region was also enhanced by PTU treatment, which suggests that PTU could upregulate StAR gene expression. In addition to SF-1 regulation, we found that mitogen-activated protein (MAP) kinase kinase activation is an important regulator of PTU-stimulated StAR protein expression, based on the effects of the MEK inhibitor PD98059. In conclusion, these results indicate that PTU plays opposite roles in the production of progesterone and its precursor, pregnenolone. The regulation of negative feedback on speeding the cholesterol transportation and pregnenolone conversion after a 16-h PTU treatment may be the mechanism explaining PTU's inhibition of progesterone production in rat granulosa cells.

Abstract
Vasculitis comprises a broad group of syndromes characterized by inflammation and necrosis on the walls of blood vessels, resulting in narrowing or occlusion of the lumen. The distribution of involved blood vessel varies considerably and serves as the basis for one classification of vasculitic syndromes: large vessels (Takayasu arteritis, giant cell arteritis); medium and small muscular arteries (polyarteritis nodosa, Churg-Strauss syndrome, Wegener's granulomatosis, vasculitis in rheumatic diseases); and small vessels ("hypersensitivity" vasculitis, Henoch-Schonlein purpura, microscopic polyangiitis, cryoglobulinemia). This article reviews medium and large vessel vasculitis and current treatment options; it also presents a comprehensive approach to diagnosing and treating patients with suspected cutaneous vasculitis.

Abstract
BACKGROUND Propylthiouracil (PTU) has been used in the treatment of hyperthyroidism for many years and inhibits the enzyme 5'-deiodinase, which converts thyroxine to triiodothyronine. Several studies have reported PTU as an effective treatment for plaque psoriasis. PTU exhibits immunomodulatory effects; however, its exact mechanism of action in psoriasis is unknown. Few patients were studied in these reports and treatment with PTU was continued for no longer than 8 weeks. METHODS In this study we report on four patients with resistant plaque psoriasis who had treatment with oral PTU for 4-32 weeks (mean 18.4). RESULTS Three of the four patients exhibited moderate clinical improvement with reductions in psoriasis severity observed within 4-6 weeks of commencing PTU therapy. The side effects noted were subclinical hypothyroidism in two patients and worsening of muscle aches in one patient. Monitoring included regular thyroid function, full blood count, and liver and renal function tests. CONCLUSION This study illustrates that oral PTU can be a useful addition to the therapy of resistant cases of plaque psoriasis and shows that this treatment can be continued for longer than 8 weeks with few side effects occurring secondary to PTU.

Abstract
Propylthiouracil (PTU), a thyonamide class drug commonly used to treat hyperthyroidism has been reported to cause adverse reactions in 3% to 12% of patients. The side effects have been described more frequently as mild, but ocasionally severe fatal reactions may occur. We report the case of a fourteen years old patient in use of PTU for the last three years who presented with fever, hemorrhagic blisters, necrotic ulcers, and that developed purpuric lesions and nodules in lower extremities. Laboratory and histopathologic findings were compatible with skin leukocytoclastic vasculitis, a pattern found in hypersensitivity reaction vasculitis. Suspension of PTU and introduction of prednisone, induced complete remission of symptoms and healing of the skin lesions. The importance of this study is to call attention to the occurrence of serious cutaneous manifestation with a mortality rate that might reach 10%, associated with a systemic drug frequently used in internal medicine. Early diagnosis and withdrawal of the suspected medication is mandatory. Administration of corticosteroids and/or immunosuppressives agents must be considered.

Abstract
Vasculitis presents with a range of clinical manifestations, many of which affect the skin. Diagnosing and classifying vasculitis can prove challenging. Particularly given the lack of unified criteria that are both useful as a research tool and clinically relevant. Also, vasculitis may be secondary to a wide range of conditions, making the prompt recognition and treatment of associated disorders essential for appropriate patient management. This article will highlight the classification, pathogenesis, clinical presentation, diagnosis, evaluation, and treatment of the cutaneous vasculitides.

Abstract
Palpable purpura is a concerning clinical finding in pediatric patients and can have many causes, including infectious and autoimmune processes. A rare cause, drug-induced vasculitis, may result from the production of antineutrophil cytoplasmic antibodies (ANCAs) in response to a medication. We report a girl with Turner syndrome and Graves' disease who presented with palpable purpuric lesions. The diagnosis of propylthiouracil (PTU)-associated vasculitis was made by observation of consistent clinical features, the detection of elevated ANA and ANCA in the blood, and the observed clinical resolution of symptoms following withdrawal of PTU. Subsequent treatment of persistent hyperthyroidism with radioablation did not result in an exacerbation of the vasculitis, a complication described in prior case reports.

Abstract
Substantial evidences suggested that propylthiouracil (PTU) could induced anti-myeloperoxidase (MPO) antibodies in sera from patients with hyperthyroidism, however, only a subgroup of the PTU-induced anti-MPO antibody positive patients developed clinical evident vasculitis. The aim of this study is to compare the titres and affinities of PTU induced anti-MPO antibodies in sera from patients with hyperthyroidism with and without clinical vasculitis. Anti-MPO antibody positive sera from patients diagnosed hyperthyroidism with (n = 13) and without (n = 14) clinical evident vasculitis were collected. The titre was determined by MPO-ELISA and expressed as logarithm value (lgT). The affinity constant (aK) of anti-MPO IgG was measured by antigen inhibition assay. The titre and aK values were compared between patients with and without vasculitis. In patients with vasculitis, the mean lgT of anti-MPO antibodies was 3.62 +/- 0.66; the median aK was 4.47 x 10(7)M(-1). In patients without vasculitis, the mean lgT was 2.54 +/- 0.29; the median aK was 0.14 x 10(7)M(-1), and both were significant lower than those in patients with vasculitis (t = 5.464; P = 0.000 & z = -4.373; P = 0.000, respectively). We concluded that the titre and affinity of anti-MPO antibodies might be associated with the development of clinical vasculitis in patients with PTU-induced ANCA.

Abstract
OBJECTIVE We report a case of leukocytoclastic vasculitis as a manifestation of propylthiouracil hypersensitivity. CLINICAL PRESENTATION AND INTERVENTION A 66-year-old woman with a history of a toxic adenoma was referred for evaluation of a purpuric rash on the legs and buttocks bilaterally. She was biochemically hyperthyroid. Biopsy of the skin lesions revealed leukocytoclastic vasculitis. Propylthiouracil therapy was discontinued, and methimazole started. The purpuric rash resolved and surgical treatment for toxic adenoma resulted in euthyroid state. CONCLUSION This report indicated that leukocytoclastic vasculitis should be considered in the differential diagnosis of patients with a vasculitic rash. The discontinuation of the propylthiouracil was associated with disappearance of the lesions.

Abstract
We report on a case of pulmonary capillaritis with diffuse alveolar hemorrhage in a child due to propylthiouracil (PTU). PTU treatment is a rare cause of pulmonary capillaritis in adults; we report on the first case in a pediatric patient. The treatment of pulmonary capillaritis often requires corticosteroid therapy, other immunosuppressive medications, or withdrawal of the causative agent. Our patient recovered completely after treatment with a limited course of corticosteroids and removal of PTU.

Abstract
As reações cutâneas graves adversas à droga são as que geralmente necessitam de internação hospitalar, por vezes em unidade de terapia intensiva ou de queimados, com observação minuciosa dos sinais vitais e da função de órgãos internos. O objetivo é descrever estas reações facilitando o seu reconhecimento e tratamento. Fazem parte deste grupo a Síndrome de Hipersensibilidade à Droga (SHD), a Pustulose Exantemática Generalizada Aguda (PEGA), a Necrose Cutânea induzida por Anticoagulante, as Vasculites de Pequenos Vasos (VPV), a Vasculite de Hipersensibilidade ao Propiltiouracil (VHP) e as Reações tipo Doença do Soro (RDS). A SHD tem-se tornado de elevada relevância clínica devido ao uso amplo dos anticonvulsivantes aromáticos e da dapsona, utilizada no tratamento de doenças como a acne e a hanseníase. A PEGA é determinada principalmente pelos derivados beta-lactâmicos e tem como principal diagnóstico diferencial a psoríase pustulosa generalizada. As VPV tegumentares podem refletir uma doença multissistêmica subjacente, com danos graves em órgãos nobres, como os rins, pulmões e sistema hematológico, com morbidade elevada e possível letalidade. Abordamos as características clínicas e o tratamento destas reações adversas à droga.

Abstract
Therapeutic agents from virtually every pharmacological class have been implicated in the development of drug-induced vasculitis. Clinical manifestations range from small vessel hypersensitivity vasculitis and leukocytoclastic vasculitis to clinical syndromes indistinguishable from classical systemic forms of vasculitis such as Wegener's granulomatosis, polyarteritis nodosa and Churg-Strauss syndrome (CSS). The exact pathogenic mechanisms involved remain to be elucidated; but both cell-mediated and humoral immunity appear to play important roles. Affected individuals may present with cutaneous involvement alone or life-threatening systemic involvement, which may result in severe and sometimes fatal illness. Since clinical presentation as well as serological and pathological parameters is identical to idiopathic forms of vasculitis, a high index of suspicion is necessary to accurately and expeditiously diagnose drug-induced vasculitis. Withdrawal of the offending agent alone is often sufficient to induce prompt resolution of clinical manifestations, obviating the need for systemic corticosteroids or more powerful forms of immunosuppression.

Abstract
UNLABELLED Vasculitis can range in severity from a self-limited single-organ disorder to a life-threatening disease with the prospect of multiple-organ failure. This condition presents many challenges to the physician, including classification and diagnosis, appropriate laboratory workup, treatment, and the need for careful follow-up. The physician must not only be able to recognize vasculitis but also be able to provide a specific diagnosis (if possible) as well as recognize and treat any underlying etiologic condition. Most diagnostic criteria are based on the size of vessel involvement, which often correlates with specific dermatologic findings. This may allow the dermatologist to provide an initial diagnosis and direct the medical evaluation. This article reviews the classification and diagnosis of cutaneous vasculitic syndromes and current treatment options; it also presents a comprehensive approach to diagnosing and treating the patient with suspected cutaneous vasculitis. (J Am Acad Dermatol 2003;48:311-40.) LEARNING OBJECTIVE At the completion of this learning activity, participants should be familiar with the classification and clinical features of the various forms of cutaneous vasculitis. They should also have a rational approach to diagnosing and treating a patient with vasculitis.

Abstract
Propylthiouracil (PTU) is a thioamide drug used clinically to inhibit thyroid hormone production. However, PTU is associated with some side effects in different organs. In the present study, the acute and direct effects of PTU on testosterone production in rat Leydig cells were investigated. Leydig cells were isolated from rat testes, and an investigation was performed on the effects of PTU on basal and evoked-testosterone release, the functions of steroidogenic enzymes, including protein expression of cytochrome P450 side-chain cleavage enzyme (P450(scc)) and mRNA expression of the steroidogenic acute regulatory protein (StAR). Rat Leydig cells were challenged with hCG, forskolin, and 8-bromo-cAMP to stimulate testosterone release. PTU inhibited both basal and evoked-testosterone release. To study the effects of PTU on steroidogenesis, steroidogenic precursor-stimulated testosterone release was examined. PTU inhibited pregnenolone production (i.e., it diminished the function of P450(scc) in Leydig cells). In addition to inhibiting hormone secretion, PTU also regulated steroidogenesis by diminishing mRNA expression of StAR. These results suggest that PTU acts directly on rat Leydig cells to diminish testosterone production by inhibiting P450(scc) function and StAR expression.

Abstract
OBJECTIVE To evaluate the literature for published cases of drug-induced vasculitis with cutaneous and/or systemic manifestations. DATA SOURCES The MEDLINE database was searched from 1965 to December 1999 for articles focusing on drugs and vasculitis, using various search terminologies (e.g., Churg-Strauss syndrome, Goodpasture's syndrome, Henoch-Schönlein purpura, various drugs suspected to induce vasculitis). Cases were included when they met the established criteria as described in the methodology. DATA SYNTHESIS Drugs found to be most frequently associated with vasculitis were propylthiouracil, hydralazine, colony-stimulating factors, allopurinol, cefaclor, minocycline, D-penicillamine, phenytoin, isotretinoin, and methotrexate. The interval between the first exposure and appearance of symptoms was reported to be extremely variable (hours to years). Vasculitis has occurred after drug dosage increases and after rechallenge with the suspected drug. In the majority of cases, vasculitis has resolved after discontinuing the drug. Patients with more severe, often life-threatening, manifestations have required treatment with corticosteroids, plasmapheresis, hemodialysis, or cyclophosphamide. Death was the result in 10% of all published cases, with a predominance in patients in whom multiple organ systems were involved. CONCLUSIONS Clinicians need to be suspect of drug-induced vasculitis to enable prompt diagnosis and treatment. This should improve patient outcomes based on the data referenced for this article.

Abstract
A 71-year-old man with acrodermatitis continua of Hallopeau was treated successfully with a combination of oral propylthiouracil and methotrexate. After 14 weeks, he developed acute pancytopenia, an uncommon idiosyncratic side-effect of propylthiouracil, and presented with a life-threatening methicillin-resistant Staphylococcus aureus pneumonia. This illustrates the potential value and associated risks of propylthiouracil in the management of this difficult condition.
