Association of uric acid with kidney function and albuminuria: the Uric Acid Right for heArt Health (URRAH) Project
2021
Abstract Background Hyperuricemia is commonly observed in patients with chronic kidney disease (CKD). However, a better understanding of the relationship among uric acid (UA) values, glomerular filtration rate (GFR) and albuminuria may shed light on the mechanisms underlying the excess of cardiovascular mortality associated with both chronic kidney disease and hyperuricemia and lead to better risk stratification. Our main goal was to study the relationships between serum uric acid and kidney disease measures (namely estimated GFR [eGFR] and albuminuria) in a large cohort of individuals at cardiovascular risk from the URic acid Right for heArt Health (URRAH) Project database. Methods Clinica…
Position paper on liver and kidney diseases from the Italian Association for the Study of Liver (AISF), in collaboration with the Italian Society of …
2021
Abstract Liver and kidney are strictly connected in a reciprocal manner, in both the physiological and pathological condition. The Italian Association for the Study of Liver, in collaboration with the Italian Society of Nephrology, with this position paper aims to provide an up-to-date overview on the principal relationships between these two important organs. A panel of well-recognized international expert hepatologists and nephrologists identified five relevant topics: 1) The diagnosis of kidney damage in patients with chronic liver disease; 2) Acute kidney injury in liver cirrhosis; 3) Association between chronic liver disease and chronic kidney disease; 4) Kidney damage according to dif…
Objective tinnitus secondary to palatal tremor: Two case reports and brief literature review.
2021
Abstract Objective tinnitus is defined as a type of tinnitus perceived by both the patient and external observer. This paper presents two cases of objective tinnitus related to palatal tremor, along with a literature review. Palatal tremor is a condition characterized by soft palate involuntary contractions. Two types of palatal tremor have been described: symptomatic palatal tremor and essential palatal tremor, with different clinical manifestations. Diagnostic workup is based on medical history and physical examination, including direct oropharynx exploration and cavum visualization through nasopharyngoscopy. Brain MRI is mandatory in all cases. If a secondary origin is suspected, additio…
Stem cell-secreted factor therapy regenerates the ovarian niche and rescues follicles.
2021
Background Ovarian senescence is a normal age-associated phenomenon, but increasingly younger women are affected by diminished ovarian reserves or premature ovarian insufficiency. There is an urgent need for developing therapies to improve ovarian function in these patients. In this context, previous studies suggest that stem cell–secreted factors could have regenerative properties in the ovaries. Objective This study aimed to test the ability of various human plasma sources, enriched in stem cell–secreted factors, and the mechanisms behind their regenerative properties, to repair ovarian damage and to promote follicular development. Study Design In the first phase, the effects of human pla…
French Endocrine Society Guidance on endocrine side effects of immunotherapy.
2018
The management of cancer patients has changed due to the considerably more frequent use of immune checkpoint inhibitors (ICPIs). However, the use of ICPI has a risk of side effects, particularly endocrine toxicity. Since the indications for ICPI are constantly expanding due to their efficacy, it is important that endocrinologists and oncologists know how to look for this type of toxicity and how to treat it when it arises. In view of this, the French Endocrine Society initiated the formulation of a consensus document on ICPI-related endocrine toxicity. In this paper, we will introduce data on the general pathophysiology of endocrine toxicity, and we will then outline expert opinion focusing…
Tertiary hyperparathyroidism: a review
2021
Abstract: Tertiary hyperparathyroidism (HPT III) occurs when an excess of parathyroid hormone (PTH) is secreted by parathyroid glands, usually after longstanding secondary hyperparathyroidism. Some authorities reserve the term for secondary hyperparathyroidism that persists after successful renal transplantation. Long-standing chronic kidney disease (CKD) is associated with several metabolic disturbances that lead to increased secretion of PTH, including hyperphosphatemia, calcit-riol deficiency, and hypocalcaemia. Hyperphosphatemia has a direct stimulatory effect on the parathyroid gland cell resulting in nodular hyperplasia and increased PTH secretion. Prolonged hypocalcaemia also causes …
Prospective Study of Parathyroid Graft Function in Patients with Renal Hyperparathyroidism After Total Parathyroidectomy and Heterotopic Autotranspla…
1999
Evaluation of the value of gradients for intact parathyroid hormone after total parathyroidectomy and heterotopic autotransplantation for renal hyperparathyroidism.Prospective long-term follow-up study.Teaching hospital, Germany.A total of 115 patients operated on for renal hyperparathyroidism between 1 August 1987 to 15 August 1997.100/115 had total parathyroidectomy with autotransplantation.Analyses of serum calcium, alkaline phosphatase, and intact parathormone in serum 1, 4, 8, 12, 18 and 24 months postoperatively and annually thereafter. Parathormone gradients were calculated as the ratio of the parathormone concentrations in the antecubital venous blood of the grafted and the non-graf…
Blood Brain Barrier Compromise with Endothelial Inflammation may Lead to Autoimmune Loss of Myelin during Multiple Sclerosis
2009
Multiple sclerosis is an autoimmune disease characterized by multifocal areas of inflammation and demyelination within the central nervous system. The mechanism that triggers the disease remains elusive. However, recent findings may indicate that multiple sclerosis, at its source, could be a hemodynamic disorder. It has been found that multiple sclerosis patients exhibit significant stenoses in extracranial veins draining the central nervous system (in azygous and internal jugular veins), which are associated with significant pressure gradients measured across strictures. Such anatomic venous abnormalities were not found in the control group of healthy subjects. In this review, it is hypoth…
Chronic cerebrospinal venous insufficiency is unlikely to be a direct trigger of multiple sclerosis
2013
Abstract Background Chronic cerebrospinal venous insufficiency, a vascular pathology affecting the veins draining the central nervous system can accompany multiple sclerosis and is suspected to be involved in its pathogenesis. Objective This study was aimed at exploring a potential role for chronic cerebrospinal venous insufficiency in triggering multiple sclerosis. If it were venous abnormalities responsible for neurological pathology, one should expect negative correlation, i.e. more severe vascular lesions in the patients with early onset of multiple sclerosis. Methods Localization and degree of venous blockages in 350 multiple sclerosis patients were assessed using catheter venography. …
CD15 – A new marker of pathological villous immaturity of the term placenta
2014
Abstract Introduction Idiopathic immaturity is one of the main reasons for latent placental insufficiency and antenatal hypoxia. Postnatal identification of the immature placental phenotype may help early stratification of a heterogeneous population of newborns and individually identify risk of disease in the immediate postnatal life. The aim of the study was to determine the relevant diagnostic markers associated with pathological placental immaturity. Methods 111 tissue samples from normal and pathological term placentas with persisting villous immaturity comprised the comparative immunohistochemical study (CD15, CD34). Positive immunohistochemical reactions were quantitatively assessed i…
