Cardiovascular-Renal Consequences of Reducing Renal Mass After Living Kidney Donation
Kidney FailureHypertension4 moreA reduce in renal mass may result in remnant single nephron hyperfiltration, with associated proteinuria and an accelerated loss of kidney function. Live-donor kidney transplantation is generally considered the best choice for patients who have renal failure and are awaiting transplantation, because these kidneys function better than kidneys from deceased donors, and waiting times for deceased-donor transplants are long Although several studies have shown that kidney donation has low short-term morbidity and mortality, the data on long-term outcomes are much less complete. This study is designed to prospectively evaluate the effects of unilateral nephrectomy on cardiovascular-renal functions of donors after living kidney donation: the development of hypertension, albuminuria, renal failure, inflammatory and endothelial changes.
Keratinocyte Growth Factor and Cytokines in Burns.
BurnsGrowth Factors3 moreKERATINOCYTE GROWTH FACTOR AND CYTOKINES IN SKIN BURNS. INTRODUCTION: Intense inflammatory responses are activated by burns that affect a large total body surface area. Changes in plasma levels of cytokines after burns occur before metabolic abnormalities unsettle the patient. So it may be possible to develop therapeutic interventions that may attenuate the acute inflammatory response by decreasing the expression of these cytokines. The importance of growth factors in the healing process was demonstrated in cultured keratinocytes and fibroblasts. The keratinocyte growth factor (KGF) is a growth factor active in the repair of wounds, being the most potent stimulator of mitotic cells. PURPOSE: To assess the level of keratinocyte growth factor (KGF) and IL-1ß, IL-6, IL-8, IL-10, IL-12 and TNF-alfa of patients with burns produced by cultured primary dermal fibroblasts and the gene expression. METHODS: 10 patients will be include (05 patients in the study group and 05 patients in the control group) admitted to the Burns Care Unit of the Discipline of Plastic Surgery, Federal University of São Paulo (UNIFESP) between 25% and 50% of total body surface area (TBSA), deep second-degree or third degree, with need to perform surgical debridement. The control group will be constituted by patients with less than 5% of TBSA, deep second-degree or third degree, with need to perform surgical debridement. The authors will evaluate the levels of IL-1ß, IL-6, IL-8, IL-10, IL-12p70 and tumor necrosis factor alpha (TNF-alfa) in samples of the culture media of primary dermal fibroblasts of patients selected using flow cytometry. The level of keratinocyte growth factor (KGF), in the same samples will be evaluated by ELISA. The keratinocyte growth factor (KGF) and TNF-alfa gene expression will be evaluated in the culture of primary dermal fibroblasts from the same patients. The gene expression of KGF and cytokines will be done by qRT-PCR and RT-PCR array. The experiments will be done in duplicate.
Periodontal and Periapical Inflammation and Pregnancy
Periodontal DiseasePeriapical Disease4 moreThis is a retrospective chart review of patient records at the University of Mississippi Medical Center. We are not actively recruiting patients for this study. Recent animal studies we conducted showed that periapical abscesses during pregnancy cause a systemic inflammatory response in the mother. Also due to the increase in TNF-alpha (an inflammatory cytokine) the mother also become insulin resistant and thus developed gestational diabetes. Periodontal inflammation has been shown in the research to lead to low-birth weight and pre-term birth. We are looking retrospectively to see if an association exists in charted data between periapical and periodontal inflammation and adverse pregnancy outcomes.
Effects of Multiple Nasal Exposures to House Dust Mite Allergen on Nasal and Body Inflammation and...
Allergic RhinitisThis study will evaluate whether multiple nasal antigen challenges with dust mite allergen produces increases in nasal symptoms and local allergic inflammatory cells in the nose and the blood.
A Study Evaluating the Association of Inflammation With Hemodialysis Access Type
End Stage Renal DiseaseInflammationTo determine if the type of hemodialysis vascular access correlates with markers of inflammation, namely C-reactive protein and interleukin-6, and with both access and patient survival in the end stage renal disease population.
Vascular Access for Hemodialysis and Inflammation
Vascular Access for Hemodialysis and InflammationThe aim of the present study was to investigate patients free of active infection and/or thrombosis to assess if the type of vascular access (AVF, AVG, TCC), could influence: the levels of serological markers of inflammation (CRP, IL-6, TNF-a); the degree of expression on monocyte surface of inflammation and immune response modulating molecules: CD14, CD32 and CD44. the amount of monocytic cells expressing a senescent phenotype (CD14 and CD32).
Examining the Link Between Obesity, Inflammation, and Response to Asthma Medications
AsthmaObesityAsthma is a common, long-term disease that is caused by inflammation of the airways. Inflammation also plays a role in obesity and may affect the way a person responds to asthma medication. This study will examine the relationship between obesity and inflammation and the effect they have on response to corticosteroid asthma medications.
Towards a High-fat Feeding Intervention Study: Identification of Markers for Inflammation and Organ...
Systemic Inflammatory Response SyndromeSepsisPatients undergoing major surgery, trauma or burns are prone to develop an exacerbated inflammatory response, which is potentially lethal to the individual. Recently, the researchers' group showed in a rodent model of hemorrhagic shock that high-fat feeding administered before shock attenuates inflammation and reduces intestinal and hepatic damage. In the mechanism that underlies this protective effect, the release of cholecystokinin in gut wall and activation of efferent vagus bundles are crucial events. Before investigating the effect of high-fat nutrition in clinical setting, suitable markers of inflammation and organ damage need to be selected. In this study, blood will be collected in patients undergoing different types of operations. Consequently several markers for inflammation and organ damage will be determined. Hence, suitable parameters for a future high-fat intervention study will be selected.
