Anderson-Fabry disease is a rare lysosomal storage disorder. It results from a deficiency of the lysosomal alpha-galactosidase A and leads to progressive accumulation of globotriaosylceramide in the endothelium and tissue cells of various organs. Some of the typical clinical findings such as tiredness, dry skin, myalgia and arthralgia as well as vague gastrointestinal complaints are also symptoms of hypothyroidism. Therefore, we studied the thyroid function in patients with Anderson-Fabry disease. Thyroid function was studied in 11 patients (6 female, 5 male) with Anderson-Fabry disease by measuring thyroid-stimulating hormone (TSH) and free thyroxine serum levels. Nine patients had chronic kidney disease with stage 1 and two with stage 5. Subclinical hypothyroidism (normal serum free thyroxine concentrations along with elevated serum TSH levels) was found in 4 of 11 patients (36.4%). Subclinical hypothyroidism was observed in both male and female patients as well as in patients with stage 1 and stage 5 kidney disease. Subclinical hypothyroidism is a common finding in patients with Anderson-Fabry disease, showing an excess prevalence as compared to the normal population. The high frequency seems to be relevant regarding the potential consequences of a hypothyroid state.

In a retrospective study of 309 cases of hypothyroidism seen at King Fahd Hospital of the University (KFHU), Al-Khobar, 124 (90 Saudis and 34 non-Saudis) adult patients with spontaneous primary hypothyroidism satisfied the inclusion criteria for detailed analysis. Their male:female ratios for Saudis and non-Saudis were 1:4.6 and 1:3.9 respectively. The majority were diagnosed in their third and fourth decades. The prevalence of previously undiagnosed spontaneous and biochemically overt primary hypothyroidism in Saudis was 5.2/1000 females and 0.94/1000 males. FT4I was normal in 43 (35%) and low in 81 (65%). FT4I correlated with cold intolerance, constipation, dry skin, hoarseness, delayed reflex relaxation, and coarse and cold skin. In rank order, presenting symptoms in those with low FT4I were tiredness (56%), cold intolerance (38%), constipation, weight gain, menstrual disturbance - especially amenorrhea - (36% each), dry skin (35%), hoarseness (31%); signs were coarse skin (53%), delayed reflex relaxation (32%), cold skin and goiter (24% each). The above clinical findings may help physicians in the early detection of primary hypothyroidism. Population-based studies are necessary to provide more data on this disease in this country.

The introduction of potent anti-retroviral treatment (ART) has transformed HIV disease into a chronic condition with the prospect, for the patient, of strict adherence to effective but life-long treatments. Within this framework, a major issue that can negatively affect adherence is the side-effects of the treatment. To date, studies documenting how individuals HIV-infected through drug injection (IDUs) experience ART-related side effects are sparse. Longitudinal data collected from the APROCO-COPILOTE cohort have been used to compare the experience of ART-related side-effects who have been HIV-infected via injecting drug use and non-IDU patients. A 20-item list was used to collect self-reported side-effects over a 7-year follow up period. Of 922 patients, 15% were IDUs. At any given visit, IDUs reported a significantly higher number of side-effects and had approximately twice the risk of reporting any side effect than non-IDUs. Most commonly reported side-effects were dry skin, fatigue, vomiting, bone troubles, insomnia. After adjustment for social conditions, depressive symptoms, use of sleeping pills and time since HIV diagnosis, IDUs reported experiencing significantly more side-effects than non-IDUs. Whether or not this is related to sensitivity to pain or to other comorbidities is difficult to establish. Further research is needed to understand how substitution treatment can mediate the relationship between exposure to opioids and side-effects. Providing appropriate care to reduce side-effects, thereby increasing adherence to ART in this population, remains a major challenge especially in those countries scaling up ART. Incorporating symptom management and improving access to analgesic medications within a model of comprehensive care for HIV-infected IDUs, could reduce the impact of drug-related and HIV-related harms and induce better long-term treatment outcomes and quality of life.

Symptoms consistent with hypothyroidism or adrenal insufficiency, such as lethargy, anorexia, cold intolerance, weakness, hypotension or paraesthesia, are frequently reported in the literature in patients with Human African Trypanosomiasis (HAT), but an endocrine origin for these symptoms has not yet been demonstrated. Thyroid and adrenocortical function were assessed in 60 patients with late-stage HAT and compared to those in 60 age- and gender-matched healthy controls. Clinical assessment and endocrine laboratory examinations were performed on admission, within 2 days after the end of treatment and at follow-up 3 months later. Signs and symptoms of hypothyroidism, such as fatigue, cold sensation, constipation, paraesthesia, peripheral oedema and dry skin, were significantly more frequent in HAT patients than in the controls. However, these signs and symptoms could not be attributed to hypothyroidism due to the lack of supporting laboratory data, and thus empirical replacement therapy for the clinically suspected hypothyroidism was not warranted. Signs and symptoms consistent with adrenal insufficiency, such as weakness, anorexia, weight loss or hypotension, were significantly more frequent in HAT patients than in controls, but they could not be associated with an insufficiency of the adrenocortical axis. Higher basal levels of cortisol were found in HAT patients than in controls, which can be viewed as a stress response to the infection. However, a transitory adrenal insufficiency was suspected in 8% of HAT patients at admission and in 9% at discharge. All values were normal at follow-up 3 months later.

The thyroid gland produces hormones critical to the maintenance of the cellular metabolic rate. The actions of these hormones are far-reaching, affecting thermoregulation and calorigenesis; the metabolism of carbohydrates, fats, and proteins; and oxygen utilization. Thyroid hormones also appear to act synergistically with epinephrine and enhance tissue sensitivity to catecholamines. Signs and symptoms of hypothyroidism include listlessness, fatigue, cold intolerance, dry skin, hair loss, constipation, weight gain, muscle soreness, and slow heart rate. Signs and symptoms of hyperthyroidism include irritability, heat intolerance, tremors, increased sweating, frequent bowel movements, and quickened heart rate. The effect of inadequately treated or undiagnosed hyperthyroidism on the heart carries perioperative risks. To provide competent dental care to patients with thyroid dysfunction, clinicians must understand the disease, its treatment, and the impact the disease and its treatment may have on the patient's ability to undergo and respond to dental care.

Sorafenib (Nexavar) is an orally active multikinase inhibitor that is approved in the EU for the treatment of hepatocellular carcinoma. Monotherapy with sorafenib prolongs overall survival and delays the time to progression in patients with advanced hepatocellular carcinoma who are not candidates for potentially curative treatment or transarterial chemoembolization. Sorafenib is generally well tolerated in patients with advanced hepatocellular carcinoma. Thus, sorafenib represents an important advance in the treatment of advanced hepatocellular carcinoma and is the new standard of care for this condition. The bi-aryl urea sorafenib is an oral multikinase inhibitor that inhibits cell surface tyrosine kinase receptors (e.g. vascular endothelial growth factor receptors and platelet-derived growth factor receptor-beta) and downstream intracellular serine/threonine kinases (e.g. Raf-1, wild-type B-Raf and mutant B-Raf); these kinases are involved in tumour cell proliferation and tumour angiogenesis. In vitro, dose-dependent inhibition of cell proliferation and induction of apoptosis was seen with sorafenib in human hepatocellular carcinoma cells lines. Sorafenib demonstrated dose-dependent antitumour activity in a murine xenograft model of human hepatocellular carcinoma. Steady-state plasma concentrations were reached within 7 days in patients with advanced, refractory solid tumours who received twice-daily oral sorafenib. Metabolism of sorafenib occurs primarily in the liver and is mediated via cytochrome P450 (CYP) 3A4 and uridine diphosphate glucuronosyltransferase 1A9. In advanced hepatocellular carcinoma, differences in sorafenib pharmacokinetics between Child-Pugh A and B patients were not considered clinically significant. Sorafenib may be associated with drug interactions. For example, sorafenib exposure was reduced by an average 37% with concomitant administration of the CYP3A4 inducer rifampicin (rifampin); sorafenib concentrations may also be decreased by other CYP3A4 inducers. Monotherapy with oral sorafenib 400 mg twice daily prolonged median overall survival and delayed the median time to progression in patients with advanced hepatocellular carcinoma, according to the results of two randomized, double-blind, placebo-controlled, multicentre, phase III trials (the SHARP trial and the Asia-Pacific trial). There was no significant difference between sorafenib and placebo recipients in the median time to symptomatic progression in either trial. The vast majority of patients included in these trials were Child-Pugh A. Combination therapy with sorafenib plus doxorubicin did not delay the median time to progression to a significant extent compared with doxorubicin alone in patients with advanced hepatocellular carcinoma, according to the results of a randomized, double-blind, phase II trial. However, the median durations of overall survival and progression-free survival were significantly longer in patients receiving sorafenib plus doxorubicin than in those receiving doxorubicin alone. Combination therapy with sorafenib plus tegafur/uracil or mitomycin also showed potential in advanced hepatocellular carcinoma, according to the results of noncomparative trials. Monotherapy with oral sorafenib was generally well tolerated in patients with advanced hepatocellular carcinoma, with a manageable adverse effect profile; diarrhoea and hand-foot skin reaction were consistently the most commonly occurring drug-related adverse events in clinical trials. In the SHARP trial, drug-related adverse events of any grade occurring in significantly more sorafenib than placebo recipients included diarrhoea, hand-foot skin reaction, anorexia, alopecia, weight loss, dry skin, abdominal pain, voice changes and 'other' dermatological events. A similar tolerability profile was seen in the Asia-Pacific trial. As expected given the addition of a chemotherapy agent, the adverse event profile in patients with advanced hepatocellular carcinoma who received combination therapy with sorafenib plus doxorubicin differed somewhat to that seen with sorafenib monotherapy in the SHARP trial. In patients receiving sorafenib plus doxorubicin, the most commonly occurring all-cause adverse events (all grades) included fatigue, neutropenia, diarrhoea, elevated bilirubin levels, abdominal pain, hand-foot skin reaction, left ventricular dysfunction, hypertension and febrile neutropenia.

Sunitinib is an oral oxindole multitargeted kinase inhibitor that inhibits certain receptor tyrosine kinases (RTKs). These include vascular endothelial growth factor receptors (VEGFR type 1 and 2), platelet-derived growth factor receptors (PDGFR-alpha and PDGFR-beta), stem cell factor receptor (KIT), FMS-like tyrosine kinase-3 (FLT3), glial cell-line derived neurotrophic factor receptor (RET) and the receptor of macrophage-colony stimulating factor (CSF1R). Examination of the antitumor effect of sunitinib in a variety of cell lines in vitro suggested an antiproliferative activity that is dependent on the presence of constitutively active RTK targets. The use of sunitinib as first-line therapy in advanced renal cell carcinoma (RCC) has improved the overall survival compared with that observed after cytokine therapy, while its administration in patients with gastrointestinal stromal tumors (GISTs) after progression or intolerance to imatinib achieved an objective response of 7%. Sunitinib is currently approved for the treatment of GISTs in this setting, and as first-line therapy for the treatment of advanced RCC. The relatively long half-life of sunitinib and its major metabolite allow for a once-daily dosing schedule. An interesting antitumor activity of sunitinib was reported in phase II studies of patients with a variety of malignancies, such as hepatocellular cancer, pancreatic neuroendocrine tumors, and non-small cell lung cancer; results of phase III studies are urgently anticipated. Fatigue is one of the most common adverse effects of sunitinib, as 50-70% of patients with advanced RCC and GIST complained of this adverse effect. Other adverse effects are diarrhea, anorexia, nausea and vomiting, oral changes and bleeding events. Most toxicities are reversible and should not result in discontinuation of sunitinib. If necessary, dose adjustments or interruptions should be made. Hypothyroidism has been described in the first 2 weeks of sunitinib therapy and its incidence increases progressively with the duration of therapy. Sunitinib may exert its hypertensive activity through a direct effect on the vasculature, while its most important cardiac adverse effect is left ventricular dysfunction. A variety of skin adverse effects have been described with the use of sunitinib such as hand-foot syndrome, yellow discoloration of the skin, dry skin, subungual splinter hemorrhages, acral erythema, and generalized skin rashes. Administration of sunitinib in the adjuvant and neoadjuvant setting of patients with RCC and of its combination with chemotherapy and other targeted therapies are currently under intense investigation.

The purpose of this study was to determine which symptoms are the most reported occur most frequently, have the greatest severity, and cause the most bother for patients on hemodialysis (HD), and to determine if the symptoms experienced differ between the first (HD1) and second (HD2) treatments of the week. An observational, comparative design was used to determine participants' HD symptoms experienced on HD1 and HD2, and the effect of the symptom experience on quality of life (QOL). One hundred subjects were recruited from five dialysis centers. The adapted Dialysis Frequency, Severity, and Symptom Burden Index (DFSSBI) and the Medical Outcomes Study Short Form 36 (MOS SF 36) were administered (N = 99) on HD1 and the DFSSBI again on HD2. Data were analyzed for significance among symptom experience test scores in relation to HD1 and HD2, QOL, and gender and age. Of 31 symptoms assessed respondents reported an average of 9.77 symptoms on HD1 and 7.51 symptoms on HD2. Overall, more symptoms were reported and were more frequent, severe, and bothersome on HD1 when the level of metabolic waste is highest. The most reported symptoms included tiredness, dry skin, difficulty falling asleep, itching, numbness/tingling, difficulty staying asleep, decreased interest in sex, and bone/joint pain. Females scored consistently higher than males in the four symptom dimensions. Respondents reported about the same as the population norm (50) on the physical component summary score of the MOS SF 36 and higher than the norm (65.23) on the mental component summary score. The study found patients on HD experience multiple symptoms that can be frequent, severe, and bothersome. Interventions should be developed and tested to reduce symptom bother and improve QOL.

Postpartum thyroiditis (PPT) is the occurrence of de novo autoimmune thyroid disease, excluding Graves' disease, in the first year postpartum. The incidence of PPT is 5.4% in the general population, and it is increased in individuals with other autoimmune diseases such as type 1 diabetes mellitus. The classic presentation of PPT of hyperthyroidism followed by hypothyroidism is seen in 22% of cases. The majority of women with PPT experience an isolated hypothyroid phase (48%), with the remainder experiencing isolated thyrotoxicosis (30%). Up to 50% of women who are thyroid antibody positive (thyroid peroxidase antibody and/or thyroglobulin antibody) in the first trimester will develop PPT. Symptoms are more common in the hypothyroid phase of PPT and include fatigue, dry skin, and impaired memory. Despite multiple studies exploring the relationship between PPT and postpartum depression, or postpartum depression in thyroid antibody-positive euthyroid women, the data are conflicting, and no firm conclusions can be reached. Long-term follow-up of women who had an episode of PPT reveals a 20-40% incidence of permanent primary hypothyroidism. In a single study, selenium administration significantly decreased the incidence of PPT, but replication of the findings is needed before the recommendation can be made that all pregnant thyroid peroxidase antibody-positive women receive selenium. The indication for treating the hyperthyroid phase of PPT is control of symptoms, whereas treatment of the hypothyroid phase of PPT is indicated for symptomatic relief as well as in women who are either breastfeeding or attempting to conceive.
