Oral burning with dysphagia and weight loss

Fibromyalgia is a disorder characterized by an abnormal pain regulation. Widespread pain, fatigue, and sleep disturbance are the prevalent symptoms. When unusual symptoms are overbearingly predominant at clinical presentation, the diagnosis becomes challenging. We report on the case of a patient with fibromyalgia, who presented with dysphagia, odynophagia, and glossodynia as prevalent symptoms. Difficulty in swallowing gradually developed over a month prior hospitalization, and worsened progressively so that nourishment and fluid intake were impeded. Because anemia with mild iron deficiency was found, esophagogastroduodenoscopy was performed, but no lesions were seen in the upper digestive tract. Levels of zinc and vitamin B12 were normal. Intense pain at pelvis and the inferior limbs, which was at a first glance referred to as osteoarthrosis, associated with oral symptoms and feeling of being in the clouds allowed us to diagnose fibromyalgia. Amitriptyline was used, with relief of symptoms. Although oropharyngeal symptoms were occasionally reported in fibromyalgia, they are often overlooked. The present case, therefore, testifies the need to consider the diagnosis of fibromyalgia when the patient presents with such symptoms that cannot be readily explained on other grounds

Treatment of atherosclerotic renovascular hypertension: review of observational studies and a meta-analysis of randomized clinical trials.

open9Atherosclerotic renal artery stenosis can cause ischaemic nephropathy and arterial hypertension. We herein review the observational and randomized clinical trials (RCTs) comparing medical and endovascular treatment for control of hypertension and renal function preservation. Using the Population Intervention Comparison Outcome (PICO) strategy, we identified the relevant studies and performed a novel meta-analysis of all RCTs to determine the efficacy and safety of endovascular treatment when compared with medical therapy. The following outcomes were examined: baseline follow-up difference in mean systolic and diastolic blood pressure (BP), serum creatinine, number of drugs at follow-up, incident events (heart failure, stroke, and worsening renal function), mortality, cumulative relative risk of heart failure, stroke, and worsening renal function. Seven studies comprising a total of 2155 patients (1741 available at follow-up) were considered, including the recently reported CORAL Study. Compared with baseline, diastolic BP fell more at follow-up in patients in the endovascular than in the medical treatment arm (standard difference in means -0.21, 95% confidence interval (CI): -0.342 to -0.078, P = 0.002) despite a greater reduction in the mean number of antihypertensive drugs (standard difference in means -0.201, 95% CI: -0.302 to -0.1, P < 0.001). At variance, follow-up changes (from baseline) of systolic BP, serum creatinine, and incident cardiovascular event rates did not differ between treatment arms. Thus, patients with atherosclerotic renal artery stenosis receiving endovascular treatment required less anti-antihypertensive drugs at follow-up than those medically treated. Notwithstanding this, they evidenced a better control of diastolic BP.openopenCaielli P;Frigo AC;Pengo MF;Rossitto G;Maiolino G;Seccia TM;Calò LA;Miotto D;Rossi GPCaielli, P; Frigo, ANNA CHIARA; Pengo, Mf; Rossitto, G; Maiolino, G; Seccia, TERESA MARIA; Calò, La; Miotto, Diego; Rossi, Gianpaol

Endothelin-1 Drives Epithelial-Mesenchymal Transition In Hypertensive Nephroangiosclerosis

BACKGROUND: Tubulointerstitial fibrosis, the final outcome of most kidney diseases, involves activation of epithelial mesenchymal transition (EMT). Endothelin‐1 (ET‐1) activates EMT in cancer cells, but it is not known whether it drives EMT in the kidney. We therefore tested the hypothesis that tubulointerstitial fibrosis involves EMT driven by ET‐1. METHODS AND RESULTS: Transgenic TG[mRen2]27 (TGRen2) rats developing fulminant angiotensin II–dependent hypertension with prominent cardiovascular and renal damage were submitted to drug treatments targeted to ET‐1 and/or angiotensin II receptor or left untreated (controls). Expressional changes of E‐cadherin and α‐smooth muscle actin (αSMA) were examined as markers of renal EMT. In human kidney HK‐2 proximal tubular cells expressing the ET(B) receptor subtype, the effects of ET‐1 with or without ET‐1 antagonists were also investigated. The occurrence of renal fibrosis was associated with EMT in control TGRen2 rats, as evidenced by decreased E‐cadherin and increased αSMA expression. Irbesartan and the mixed ET‐1 receptor antagonist bosentan prevented these changes in a blood pressure–independent fashion (P < 0.001 for both versus controls). In HK‐2 cells ET‐1 blunted E‐cadherin expression, increased αSMA expression (both P < 0.01), collagen synthesis, and metalloproteinase activity (P < 0.005, all versus untreated cells). All changes were prevented by the selective ET(B) receptor antagonist BQ‐788. Evidence for involvement of the Rho‐kinase signaling pathway and dephosphorylation of Yes‐associated protein in EMT was also found. CONCLUSIONS: In angiotensin II–dependent hypertension, ET‐1 acting via ET(B) receptors and the Rho‐kinase and Yes‐associated protein induces EMT and thereby renal fibrosis

Quantitative Value of Aldosterone-Renin Ratio for Detection of Aldosterone-Producing Adenoma: The Aldosterone-Renin Ratio for Primary Aldosteronism (AQUARR) Study

Current guidelines recommend use of the aldosterone-renin ratio (ARR) for the case detection of primary aldosteronism followed by confirmatory tests to exclude false-positive results from further diagnostic workup. We investigated the hypothesis that this could be unnecessary in patients with a high ARR value if the quantitative information carried by the ARR is taken into due consideration

Angiotensin peptides in the regulation of adrenal cortical function

The adrenal cortex plays a key role in the regulation of metabolism, salt and water homeostasis and sex differentiation by synthesizing glucocorticoid, mineralocorticoid and androgen hormones. Evidence exists that angiotensin II regulates adrenocortical function and it has been contended that angiotensin peptides of the non-canonical branch of the renin angiotensin system (RAS) might also modulate steroidogenesis in adrenals. Thus, the aim of this review is to examine the role of the RAS, and particularly of the angiotensin peptides and their receptors, in the regulation of adrenocortical hormones with particular focus on aldosterone production

Endothelin-1 (ET-1) modulates epithelial-mesenchymal transition (EMT), which contributes to kidney tubulo-interstitial fibrosis in angiotensin II-dependent hypertension

The origin of myofibroblasts remains uncertain, but studies suggest that the epithelial cells may acquire a fibroblast-like phenotype via epithelial-mesenchymal transition (EMT). Objective of the study was to investigate whether EMT may contribute to the development of kidney fibrosis in a model of angiotensin II-dependent hypertension and to identify the role of ET-1 via ETA/ETB receptors. Transgenic rats TGRen2 (n=35) received for 4 weeks one of the following treatments a) irbesartan, b) bosentan, non selective ETA /ETB receptor antagonist, c) BMS-182874, selective ETA,antagonist, d) BMS+irbesartan, e) placebo. EMT was assessed by investigating coexpression of a marker of epithelial cell (E-cadherin) and one of myofibroblast (S100A4 or alfa-SMA) with double immunofluorescence. Specific immunoreactivity was measured using QWinStandard Leica ImageTMsoftware. A reduction in blood pressure was found only with irbesartan, whereas both bosentan and irbesartan significantly lowered tubulo-interstitial fibrosis. Coexpression of E-cadherin and S100A4, or E-cadherin and alfa-SMA, markedly decreased in the tubular cells of TGRen2 treated with irbesartan or bosentan. Alfa-SMA expression decreased after irbesartan, bosentan and BMS+irbesartan, but not after BMS. S100A4 expression was reduced after irbesartan, bosentan and BMS+irbesartan. E-cadherin increased only after irbesartan. Coexpression of the markers of myofibroblasts and kidney epithelial cells, by demonstrating the development of EMT during the onset of kidney hypertension-induced damage, suggests a crucial role of EMT in the pathogenesis of Ang II-mediated fibrosis. The reduction of myofibroblast markers not only after irbesartan, but also after blockade of ETA/ETB receptors, suggests an involvement of ET-1 in the development of Ang II-mediated EMT
