Evaluation of estimated glomerular filtration rate and clinical variables in systemic sclerosis patients.

Objectives: The most important renal complication of systemic sclerosis (SSc) is scleroderma renal crisis (SRC). Many patients demonstrate less severe renal complications, most likely associated with reduced renal blood flow and a consequent reduction in glomerular filtration rate (GFR). The mechanism of this slowly progressive form of chronic renal disease is unclear.

Three-dimensional echocardiography and 2D-3D speckle-tracking imaging in chronic pulmonary hypertension: diagnostic accuracy in detecting hemodynamic signs of right ventricular (RV) failure.

Background: Our aim was to compare three-dimensional (3D) and 2D and 3D speckle-tracking (2D-STE, 3D-STE) echocardiographic parameters with conventional right ventricular (RV) indexes in patients with chronic pulmonary hypertension (PH), and investigate whether these techniques could result in better correlation with hemodynamic variables indicative of heart failure.

Methods And Results: Seventy-three adult patients (mean age, 53±13 years; 44% male) with chronic PH of different etiologies were studied by echocardiography and cardiac catheterization (25 precapillary PH from pulmonary arterial hypertension, 23 obstructive pulmonary heart disease, and 23 postcapillary PH from mitral regurgitation). Thirty healthy subjects (mean age, 54±15 years; 43% male) served as controls.

Exercise tolerance in systemic sclerosis patients without pulmonary impairment: correlation with clinical variables.

Objectives: In systemic sclerosis (SSc) patients pulmonary vasculopathy (PV) is present in the early stage of disease and impairs dilation of affected pulmonary blood vessels, impeding pulmonary blood flow during exercise. Abnormal gas exchange findings were early investigated by cardiopulmonary exercise test (CPET).

Methods: A total of 34 female and 6 male [median age 49 (20-63) years] SSc patients with normal chest imaging and pulmonary function tests were enrolled.

Safety and infectious prophylaxis of intravenous immunoglobulin in elderly patients with membranous nephropathy.

A variety of infections has been recognized as an important cause of morbidity and mortality in patients with nephrotic syndrome, and membranous nephropathy is a common cause of this in the elderly. The reasons for infection risk are due to oedema complications, urinary loss of factor B and D of the alternative complement pathway, cellular immunity, granulocyte chemotaxis, hypogammaglobulinemia with serum IgG levels below 600 mg/dL, and secondary effects of immunosuppressive therapy. Many different prophylactic interventions have been used for reducing the risks of infection in these patients but recommendations for routine use are still lacking.

Sexual distress, sexual dysfunction and relationship quality in women with systemic sclerosis: correlation with clinical variables.

To assess the rate of sexual distress, sexual dysfunction and relationship quality and their association with clinical variables in women with systemic sclerosis (SSc), 102 sexually active women with SSc were recruited. Sexual distress, sexual dysfunction and dissatisfaction with relationship quality were investigated by Female Sexual Distress Scale Revised (FSDS-R), Female Sexual Function Index (FSFI) and Dyadic Adjustment Scale (DAS), respectively. The patients underwent medical examinations and nailfold videocapillaroscopy (NVC).

Increased intrarenal arterial stiffness may predict the occurrence of new digital ulcers in systemic sclerosis.

Objective: Patients with systemic sclerosis (SSc; scleroderma) are at high risk for the development of ischemic digital ulcers (DUs), which occur in 35-60% of SSc patients. The aim of this study was to assess the correlation between intrarenal arterial stiffness and DUs in SSc patients and to evaluate the prognostic value of Doppler indices to predict new DU occurrence.

Methods: Seventy unselected, consecutive patients with SSc (58 women and 12 men, mean ± SD age 49.

Nutritional status measured by BMI is impaired and correlates with left ventricular mass in patients with systemic sclerosis.

Objective: Systemic sclerosis (SSc) is a multisystemic chronic disease that is complicated by protein-energy malnutrition (PEM). Considering that PEM also may influence left ventricular mass (LVM), the aim of this study was to evaluate whether LVM is related to patients' nutritional status and to determine clinically relevant features of SSc.

Methods: Adult patients referring to our institution were considered.

Doppler ultrasound study of penis in men with systemic sclerosis: a correlation with Doppler indices of renal and digital arteries.

Erectile dysfunction (ED) prevalence in male systemic sclerosis (SSc) is high and its pathogenesis is unclear. The aim of the study is to assess correlation between Doppler ultrasound indices of penis and kidneys or digital arteries in male systemic sclerosis. Fourteen men with systemic sclerosis were enrolled in this study.

Clitoral blood flow in systemic sclerosis women: correlation with disease clinical variables and female sexual dysfunction.

Objectives: The objectives of this study were to investigate clitoral blood flow in SSc women compared with healthy controls and to correlate it with microvascular damage and disease clinical variables. We also evaluated the correlation between clitoral blood flow and sexual dysfunction.

Methods: Twenty-two SSc women and 20 healthy controls matched for sex and age were enrolled in this study.

Erythrocyte glutathione transferase: a non-antibody biomarker for systemic sclerosis, which correlates with severity and activity of the disease.

Erythrocyte glutathione transferase (e-GST) is a detoxifying enzyme hyper-expressed in nephropathic patients and used recently as a biomarker for blood toxicity. Systemic sclerosis (SSc) is characterized by endothelial dysfunction and fibrosis of the skin and internal organs. Renal involvement is frequent in SSc patients.

Ulcers caused by bullous morphea: successful therapy with N-acetylcysteine and topical wound care.

Bullous morphea is an uncommon form of localized scleroderma. The pathogenesis is unknown and treatment of coexistent ulcers is difficult. The pathogenesis of bullae formation in morphea is multifactorial, but reactive oxygen species production appears to play a key role.

Erectile dysfunction, endothelium dysfunction, and microvascular damage in patients with systemic sclerosis.

Introduction: Erectile dysfunction (ED) prevalence in men with systemic sclerosis (SSc) is high and can be considered a manifestation of endothelium damage.

Aim: This study aims to correlate ED with endothelial dysfunction and digital vascular damage in SSc patients.

Main Outcome Measures: The main outcome measures were erectile function, Doppler indices of cavernous arteries, flow-mediated dilation (FMD), capillaroscopic damage, skin perfusion, and digital pulsatility.

Red blood cell alterations in systemic sclerosis: a pilot study.

Aims: The aim of this work was to investigate whether systemic oxidative imbalance that occurs in patients with systemic sclerosis affects red blood cell integrity.

Methods: Reactive oxygen species, intracellular content of total thiols and molecules involved in red blood cell aging (e.g.

Skewed T-cell receptor variable β repertoire and massive T-cell activation in idiopathic orofacial granulomatosis.

Orofacial granulomatosis (OFG) is a clinicopathologic entity describing oral lesions with noncaseating granulomas including a spectrum of diseases such as the Melkersson-Rosenthal syndrome. The involvement of abnormal T-cell responses has been suggested in the pathogenesis of OFG although few and contrasting data are currently available on this issue. In a patient with OFG, we observed virtually complete CD4 and CD8 T-cell receptor (TCR) β-chain variable region (BV) repertoires at the lesion level and in circulation.

Clinical and histological outcome predictors in renal limited pauci-immune crescentic glomerulonephritis: a single centre experience.

Renal-limited vasculitis is a pauci-immune crescentic glomerulonephritis with no signs of systemic involvement, representing one of the most common causes of rapidly progressive glomerulonephritis. The study aims to examine clinical and histological features in twenty-four patients with RLV diagnosed by the Nephrology Department of Sapienza University of Rome, Italy, evaluating the role of these parameters in predicting renal survival. Patients details, clinical and histological features and outcomes were recorded at the time of renal biopsy and over a mean follow-up period of 36±6 months.

ACTH and azathioprine: antiproteinuric and lipid-lowering effect in the course of idiopathic membranous glomerulonephritis.

Idiopathic membranous glomerulonephritis is a frequent cause of nephrotic syndrome and may have a variable course, from spontaneous remission to progression on renal failure. The therapy is based on alternating steroids and chlorambucil or cyclophosphamide (Ponticelli protocol) for six months. In absence of complete or partial remission after protocol, cyclosporine, adrenocorticotropic hormone, mycophenolate mofetil, rituximab can be used for potential therapy.

Evaluation of Chronic Kidney Disease Epidemiology Collaboration equation to estimate glomerular filtration rate in scleroderma patients.

Objective: Renal involvement in SSc is often subclinical and chronic kidney disease (CKD) develops, with slow worsening of glomerular filtration rate (GFR). The present investigation was undertaken in order to study how well the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) correlates with measured GFR (mGFR) in a group of SSc patients with serum creatinine (sCr) in the normal range.

Methods: Forty-one scleroderma patients (37 females and 4 males) with a median age of 46 years were enrolled.

Subcutaneous immunoglobulin therapy in a patient with myopathic dropped head syndrome and common variable immunodeficiency.

Prominent neck extension weakness is an uncommon clinical entity, also termed dropped-head syndrome, that may be part of a generalized neuromuscular disorder. We report here the case of a woman with dropped-head syndrome and pulmonary arterial hypertension secondary to systemic sclerosis. Subsequently, she developed common variable immunodeficiency and subcutaneous immunoglobulin therapy was started.

Recurrent infections in children with nickel allergic contact dermatitis.

Some patients with nickel (Ni) allergic contact dermatitis (ACD) suffer from systemic symptoms after ingestion of Ni-rich foods, a condition termed Systemic Nickel Allergy Syndrome (SNAS). The aim of this study is to investigate in children the relationship between Ni ACD and lymphocyte subsets or susceptibility to infections. Nineteen children with Ni ACD and 18 controls matched for sex and age were enrolled.
