Filter by:Temporal volume loss is part of the natural aging process of the face. It is primarily the consequence of fat pad atrophy, but bone loss, ligament weakening, soft tissue, and muscle also contribute. . The goal of the study is to evaluate the volumizing and bio-stimulatory effects of sculptra injections in the temples.
With current antiretroviral therapy, people living with HIV reach virological suppression faster, which in turn leads to a higher life expectancy. Nevertheless, this improved survival rate is not free of other comorbidities, such as metabolic syndrome, characterized by a decrease in glucose tolerance and an increase in insulin resistance. Berberine is an alkaloid that has proven beneficial effects on both glucose tolerance and insulin resistance, but has not been tested in people living with HIV under virological suppression. We hypothesize that berberine will improve inflammatory markers and metabolic profile in this population without significant interactions nor adverse effects.
Contour deformity of face causes both functional as well as aesthetic problems for the patient. Fat being an autologous tissue source is considered as an ideal soft-tissue filler because it is abundant, readily available, inexpensive, host compatible, and can be harvested easily and repeatedly. However absorption of grafted fat is a major problem resulting in lack of consistency of final clinical outcome. Adipose tissue derived mesenchymal stem cells have the potential to enhance the viability of the grafted fat and the reliability of the final outcome of surgery. In the current study potential of mesenchymal stem cells will be studied by comparing two groups of patients requiring fat grafting for contour deformities of face. Control group will have fat graft with out enrichment with stem cells whereas experimental group will have their fat graft enriched with mesenchymal stem cells. Comparison will be made regarding viability of grafted fat in two groups.
Lipodystrophies are part of a clinically heterogeneous group of disorders characterized by loss (lipoatrophies) and / or accumulation of fat, which usually results in a change of normal tissue surface. Millions of plastic and reconstructive surgeries are performed annually to repair soft tissue defects due to trauma, tumor resection and congenital defects. Surgical options for lipoatrophy, the lipodystrophy type characterized by subcutaneous adipose tissue atrophy, include: Transfer of autologous fat, Dermis - fat graft, Skin flaps and Commercially available fillers. Currently, the most commonly filler agent used for the lipodystrophy treatment is polymethylmethacrylate, considered permanent and with a history of short- and medium-term adverse effects. Biocompatible and temporary filler agents such as hyaluronic acid, polylactic acid and collagen have been used for over 25 years for cosmetic purposes and in lipoatrophies. More recently, the use of autologous fibroblasts proved to be efficient solving acne scars and enabling dermis regeneration. Studies in mice showed that the combination of pre - adipocytes with a biomaterial is much more effective in tissue reconstitution than the injection of adipose tissue only, providing volume and also stimulating cell proliferation and differentiation with increased production of extracellular matrix. This project aims a phase I clinical trial of a filler agent, composed of mesenchymal stem cells derived from autologous adipose tissue associated with hyaluronic acid.
A follow-up study on the randomized, controlled, double-blind HIGH: low study. We will examine the participants from the HIGH: low study min. 6 months after finishing the HIGH: low study. We will look at the parameters: quality of life, sugar-metabolism, fat-metabolism, fat-redistribution and cytokines. The study will use the participants control visit, and the only additional examination will be the danish MOS-HIV questionnaire.
