The development of the immuno-suppressant drug ciclosporin in the 1980s gave a fillip to what type of surgeries?
"an ophthalmic ointment for dogs called Optimmune, manufactured by Intervet, which is part of Merck. It is also used to treat sebaceous adenitis (immune response against the sebaceous glands), pemphigus foliaceus (autoimmune blistering skin disease), Inflammatory bowel disease, anal furunculosis (anal inflammatory disease), and myasthenia gravis (a neuromuscular disease). It is sometimes prescribed for extreme cases of immune-mediated hemolytic anemia. Ciclosporin Ciclosporin, also spelled cyclosporine and cyclosporin, is an immunosuppressant medication and natural product. It is taken by mouth or by injection into a vein for rheumatoid arthritis, psoriasis, Crohn's disease, nephrotic syndrome, and in organ transplants to prevent rejection."
"given the Nobel Prize in Physiology or Medicine in 1990 for work on immunosuppression. Immunosuppressive drugs have the potential to cause immunodeficiency, which can cause increased susceptibility to opportunistic infections and decreased cancer immunosurveillance. Immunosuppressants may be prescribed when a normal immune response is undesirable, such as in autoimmune diseases. Steroids were the first immunosuppressant identified, but its side-effects limited its use, the more specific azathioprine was identified in 1960, but it was the discovery of ciclosporin in 1980(together with azathioprine) that allowed significant expansion of transplantation to less well-matched donor-recipient pairs as well as broad application to lung transplantation,"
"in a cascading series of events that cause mitochondrial energy production supporting the cell to be reduced or stopped completely. The cessation of energy production results in cellular death. Protecting mitochondria is a viable cardioprotective strategy. In 2008, an editorial in the New England Journal of Medicine called for more studies to determine if cyclosporin can become a treatment to ameliorate reperfusion injury by protecting mitochondria. To that end, in 2011 the researchers involved in the original 2008 NEJM study initiated a phase III clinical study of reperfusion injury in 1000 myocardial infarction patients in centers throughout Europe. Results of"
"radical production that hypothermia improves patient outcome following a blockage of blood flow to the brain. There are some preliminary studies that seem to indicate that treatment with hydrogen sulfide (HS) can have a protective effect against reperfusion injury. In addition to its well-known immunosuppressive capabilities, the one-time administration of cyclosporin at the time of percutaneous coronary intervention (PCI) has been found to deliver a 40 percent reduction in infarct size in a small group proof of concept study of human patients with reperfusion injury published in The New England Journal of Medicine in 2008. Cyclosporin has been confirmed in"
"in conditions such as traumatic brain injury, and has been shown in animal experiments to reduce brain damage associated with injury. Ciclosporin blocks the formation of the mitochondrial permeability transition pore, which has been found to cause much of the damage associated with head injury and neurodegenerative diseases. Ciclosporin's neuroprotective properties were first discovered in the early 1990s when two researchers (Eskil Elmér and Hiroyuki Uchino) were conducting experiments in cell transplantation. An unintended finding was that CsA was strongly neuroprotective when it crossed the blood–brain barrier. This same process of mitochondrial destruction through the opening of the MPT pore"
"act by binding the IL-2a receptor's α chain, preventing the IL-2 induced clonal expansion of activated lymphocytes and shortening their survival. They are used in the prophylaxis of the acute organ rejection after bilateral kidney transplantation, both being similarly effective and with only few side-effects. Like tacrolimus, ciclosporin (Novartis' Sandimmune) is a calcineurin inhibitor (CNI). It has been in use since 1983 and is one of the most widely used immunosuppressive drugs. It is a cyclic fungal peptide, composed of 11 amino acids. Ciclosporin is thought to bind to the cytosolic protein cyclophilin (an immunophilin) of immunocompetent lymphocytes, especially T-lymphocytes."
"Inhaled ciclosporin Ciclosporin is a cyclic polypeptide that has been used widely as an orally-available immunosuppressant. It was originally used to prevent transplant rejection of solid organs but has also found use as an orally administered agent to treat psoriasis, rheumatoid arthritis, dry eye and other auto-immune related conditions. A variety of pre-clinical and clinical studies have been and are investigating its use to treat lung-related disorders via inhalation. Formulation of the drug for inhalation purposes has proved challenging because of ciclosporin's poor aqueous solubility. Consequently, aerosol studies have often employed compatible solvents such as propylene glycol or ethanol as"
"that study were announced in 2015 and indicated that ""intravenous ciclosporin did not result in better clinical outcomes than those with placebo and did not prevent adverse left ventricular remodeling at 1 year"". This same process of mitochondrial destruction through the opening of the MPT pore is implicated in making traumatic brain injuries much worse. Ciclosporin is currently in a phase II/III (adaptive) clinical study in Europe to determine its ability to ameliorate neuronal cellular damage in traumatic brain injury. TRO40303 is a new cardioprotective compound that was shown to inhibit the MPT pore and reduce infarct size after ischemia-reperfusion."
"with regimens consisting of azathioprine and prednisone, the transplantation of kidneys to unrelated recipients (allotransplantation) was successful for the first time. For many years, this kind of dual therapy with azathioprine and glucocorticoids was the standard antirejection regimen, until ciclosporin was introduced into clinical practice (by Calne as well) in 1978. Ciclosporin has now replaced some of the azathioprine use due to a longer survival time, especially in heart-related transplantations. Moreover, despite being considerably more expensive, mycophenolate mofetil is also increasingly being used in place of azathioprine in organ transplantation, as it is associated with less bone marrow suppression, fewer"
"the vehicle for administration by nebulizer or have used more complicated aqueous-based formulations involving liposomes or other dispersions. Dry powder inhaler as well as propellant metered dose inhaler (pMDI) formulations have also been created and evaluated in the laboratory and in early clinical studies. Ciclosporin was brought to market in 1983 but the first non human aerosol studies were not published until the late 1980s. These efforts probed the anti-inflammatory and immunosuppressive properties of ciclosporin after regional deposition of drug in the lungs. Ciclosporin has been touted as a therapeutic option in moderate to severe asthmatic patients as a corticosteroid"
"problems (damage to the renal vein), clotting disorders, diabetes, consumption of ciclosporin or an unknown problem. Patients who have undergone a kidney transplant are commonly prescribed ciclosporin, an immunosuppressant drug which is known to reduce renal blood flow, increase platelet aggregation in the blood and cause damage to the endothelial tissue of the veins. In a clinical study conducted by the Nuffield Department of Surgery at the Oxford Transplant Centre, UK, transplant patients were given low doses of aspirin, which has a some anti-platelet activity. There is risk of bleeding in transplant patients when using anticoagulants like warfarin and herapin."
"Use during pregnancy may result in preterm birth; however, ciclosporin does not appear to cause birth defects. Ciclosporin is believed to work by decreasing the function of lymphocytes. It does this by forming a complex with cyclophilin to block the phosphatase activity of calcineurin, which in turn decreases the production of inflammatory cytokines by T‐lymphocytes. Ciclosporin was isolated in 1971 from the fungus ""Tolypocladium inflatum"" and came into medical use in 1983. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. The wholesale cost in the developing"
"the increase in lung transplants performed in the USA and Europe since the mid-1980s. Numbers have increased from 33 in 1988 to 1468 in 2007. Furthermore, acute cellular rejection is common after transplantation and will occur in up to 90% of patients and episodes are most likely to occur in the first post-operative year. Consequently, the application of ciclosporin by oral and IV administration has led to efforts to treat acute and acute refractory rejection by direct aerosol administration first in animal models and soon thereafter in transplant patients. Most of these early efforts were carried out by or associated"
"are avoided or withdrawn after the transplantation. Ciclosporin, considered a breakthrough immunosuppressive when first discovered in the 1980s, ironically causes nephrotoxicity and can result in iatrogenic damage to the newly transplanted kidney. Tacrolimus, which is a similar drug, also causes nephrotoxicity. Blood levels of both must be monitored closely and if the recipient seems to have declining renal function or proteinuria, a biopsy may be necessary to determine whether this is due to rejection or ciclosporin or tacrolimus intoxication . Post operatively, kidneys are periodically assessed by ultrasound to assess for the imaging and physiologic changes that accompany transplant rejection."
"resulted in the patient's discharge from hospital. In 1979 at Stanford, Jamieson performed 25 heart transplants, comprising more than 50 percent of the total performed globally at that time. In 1979, he described a series of successful transplantations in primates using cyclosporine, a fungal derivative whose immunosuppressive properties were reported by Jean-Francois Borel. Observing Roy Calne's reports on how cyclosporine led to a reduction in acute rejection and consequent longer survival rates following liver and kidney transplantation, Jamieson then demonstrated the possibility of using cyclosporine in human heart-lung transplantations. Subsequently, with Edward Stinson and Norman Shumway, he published Stanford's achievements"
"ciclosporine-ciclophilin binding inhibits calcineurin and effectively inhibits the human immune system. Without calcineurin, the activity of nuclear factor of activated T-cells and transcription regulators of IL-2 in T-lymphocytes is blocked. Ciclosporin A considerably alters the nuclear morphology of in vitro human peripheral blood mononuclear leukocytes from ovoid to a radially splayed lobulated structure. The expression levels of alanine racemase affects the level of cyclosporine production by ""T. inflatum"". Ciclosporin A was first introduced in medical use in the 1970s after an organ transplant to reduce graft rejection. This use was based on cyclosporin’s ability to interfere with lymphokine biosynthesis. Ciclosporin"
"changed to yield the predominantly ""trans"" isomer which possesses most of the beneficial effect of the drug (immunosuppression) in the treatment of organ transplantation and autoimmune diseases. Voclosporin Voclosporin is an experimental immunosuppressant drug being developed by Aurinia Pharmaceuticals. It is being studied as a potential treatment for lupus nephritis (LN) and uveitis. It is an analog of ciclosporin that has enhanced action against calcineurin and greater metabolic stability. Voclosporin was discovered by Robert T. Foster and his team at Isotechnika in the mid 1990s. Isotechnika was founded in 1993 and merged with Aurinia Pharmaceuticals in 2013. Initially, voclosporin was"

Despite the development of viable surgical techniques, liver transplantation remained experimental through the 1970s, with one year patient survival in the vicinity of 25%. The introduction of ciclosporin by Sir Roy Calne, Professor of Surgery Cambridge, markedly improved patient outcomes, and the 1980s saw recognition of liver transplantation as a standard clinical treatment for both adult and pediatric patients with appropriate indications. Liver transplantation is now performed at over one"
"HIV related illnesses. In the 1980s, people with cystic fibrosis rarely lived beyond their early teens. Drugs like Pulmozyme and tobramycin, both developed with aid from the ODA, revolutionized treatment for cystic fibrosis patients by significantly improving their quality of life and extending their life expectancies. Now, cystic fibrosis patients often survive into their thirties and some into their fifties. The 1985 Nobel Prize for medicine went to two researchers for their work related to familial hypercholesterolemia, which causes large and rapid increases in cholesterol levels. Their research led to the development of statin drugs which are now commonly used"

Azathioprine, cortisone and Anti-thymocyte globulin were the immunosuppressants used until two rejection episodes resulted in changing therapy to cyclosporine A three weeks after surgery and they were discharged from hospital at Christmas 1981. Between 1978 and 1982, he held various professorships including the Universities of Boston, Birmingham, Milwaukee, Paris and Stanford. More than twenty heart transplant procedures followed over the next three years. Under his leadership, intermittently spanning over 40 years at LMU, more than 1,000 heart transplants were performed.

"stroke, ischemia-reperfusion injury. In addition, necroptosis is noted to contribute to atherosclerosis, pancreatitis, inflammatory bowel disease, neurodegeneration, and some cancers. In solid-organ transplantation, ischemia-reperfusion injury can occur when blood returns to tissue for the first time in the transplant recipient. A major contributor to tissue damage results from activation of regulated necroptosis, which could include contributions from both necroptosis and mitochondrial permeability transition. Treatment with the drug cyclosporine, which represses the mitochondrial permeability transition effector Cyclophilin D, improves tissue survival primarily by inhibiting necrotic cell death, rather than its additional function as an immunosuppressant. Recently, necroptosis-based cancer therapy, using a"

Immunosuppressive drugs are often of the cytotoxic (chemotherapy) class, including rituximab (Rituxan) which targets B cells, and cyclophosphamide, a drug which reduces the function of the immune system. Ciclosporin has also been used in CIDP but with less frequency as it is a newer approach. Ciclosporin is thought to bind to immunocompetent lymphocytes, especially T-lymphocytes. Non-cytotoxic immunosuppressive treatments usually include the anti-rejection transplant drugs azathioprine (Imuran/Azoran) and mycophenolate mofetil (Cellcept). In the U.S., these drugs are used ""off-label"", meaning that they do not have an indication for the treatment of CIDP in their package inserts. Before"

"a team of surgeons at the University of Minnesota led by Richard C. Lillehei reported successful transplantation of the small intestine in dogs. Five years later in 1964, Ralph Deterling in Boston attempted the first human intestinal transplant, albeit unsuccessfully. For the next two decades, attempts at transplanting the small intestine in humans were met with universal failure, and patients died of technical complications, sepsis, or graft rejection. However, the discovery of the immunosuppressant ciclosporin in 1972 triggered a revolution in the field of transplant medicine. Due to this discovery, in 1988, the first successful intestinal transplant was performed in"
"is implicated in making traumatic brain injuries much worse. Ciclosporin has been used experimentally to treat cardiac hypertrophy (an increase in cell volume). Inappropriate opening of the mitochondrial permeability transition pore (MPTP) manifests in ischemia (blood flow restriction to tissue) and reperfusion injury (damage occurring after ischemia when blood flow returns to tissue), after myocardial infarction (heart attack) and when mutations in mitochondrial DNA polymerase occur. The heart attempts to compensate for disease state by increasing the intracellular to increase the contractility cycling rates. Constitutively high levels of mitochondrial cause inappropriate MPTP opening leading to a decrease in the cardiac"

The use of the operating microscope in spinal surgery allows the procedure to be performed through a smaller incision and with greater safety because the surgeon's visualization of nerve tissue is improved. Around this time, Dr. John A. McCulloch developed a technique for decompressing spinal nerves while minimizing the amount of ""collateral damage"" to supporting spinal ligaments, bones, and muscles. In contrast to traditional laminectomy, the lamina, spinous process, inter- and supraspinous ligaments are preserved. Also, the"
