The very first insulin injection to treat diabetes On January 11, 1922, 14-year-old Leonard Thompson became the first person to receive an insulin injection as a treatment for diabetes.

What happened to diabetics before insulin was discovered?

Just before Banting discovered insulin, a new and somewhat effective treatment was being promoted by Dr. Frederick Allen and Dr. Elliot Joslin, the world's leading diabetologists. The Allen Diet was an individualized starvation diet which limited carbs along with calories for people with diabetes.Jul 29, 2016

What was the most significant complication from diabetes before the invention of insulin?

(University of Chicago Press, 1984). 304 pages. The most significant complication from diabetes, before the invention of insulin, was falling into a hyperglycemic induced coma. Pioneers such as Drs. Fred Allen and Elliott P. Joslin were able to help some diabetics prolong their life by as long as a year or two with careful management of carbohydrate intake. Before insulin, dying from diabetes meant starving to death and eventually falling into coma. Diabetes patients were in such painfully malnourished states, often weighing under 70 pounds upon admittance to a hospital, that the only tragic figures who could remind these doctors of their earliest patients were victims of concentration camps during World War II or mass famine in Africa. The highlights one of those incredible moments in medical history where a new treatment literally raises people from the dead. Author Michael Bliss brilliantly illustrates one of the most significant medical findings in modern medicine while paying special attention to the facts explaining the controversies associated with its discovery. Insulin was discovered at the University of Toronto and Bliss’s position as a professor of history at the university enables him to utilize previously unpublished and privately held documents. He uses vivid detail and skillfully paints a picture of the significant gains and trying mishaps along the tenuous path to insulin discovery in the early 1900s. The story was written by Bliss to serve as a “readable and definitive history of the discovery of insulin,” aimed at academics and lay readers alike. It is a compelling and heartwarming story that any reader, not just medical professionals and diabetics, could enjoy. Some passage Continue reading >>

How has diabetes changed in the past 50 years?

The lives of people with diabetes has changed considerably in 50 years. They now have specific tools and easier access to information than ever before. The healthcare professionals who treat them also know more about the complexity of the disease, and which treatments work best. Pending the next medical revolution, Diabetes Québec is demanding the implementation of a national strategy to fight diabetes – a strategy founded on education, prevention, support and treatment. The last 60 years have clearly demonstrated that people with diabetes who are well informed, properly supported and treated appropriately live longer lives in better health. The discovery of insulin and glycemic control Insulin, discovered in 1921 by the legendary Banting, Best and MacLeod collaboration, is nothing short of a miracle. Worldwide, it has saved thousands of patients from certain death. Before the discovery of insulin, diabetics were doomed. Even on a strict diet, they could last no more than three or four years. However, despite the many types of insulin and the first oral hypoglycemic agents that came to market around 1957 in Canada, glycemia control – the control of blood glucose (sugar) levels – still remains an imprecise science. In the 1950s, the method a person used to control his blood glucose levels was to drop a reagent tablet into a small test tube containing a few drops of urine mixed with water. The resulting colour – from dark blue to orange – indicated the amount of sugar in the urine. Even when they monitored their patients closely, doctors realized that blood glucose levels had to be much better controlled in order to delay the major complications significantly affecting their patients’ lives: blindness, kidney disease, gangrene, heart attack and stroke.

Nowadays, the ready supply of processed food has weakened the association between wealth and eating more, but obesity, diet, and a lack of exercise are still risk factors for type 2 diabetes.

When was diabetes first discovered?

The earliest known mention of diabetes appeared in 1552 B.C. in a 3rd Dynasty Egyptian papyrus authored by Hesy-Ra, one of the world’s first documented physicians, who wrote about an illness resulting in frequent urination...which we now know is one of the key symptoms of the condition. And in the first century A.D., ancient Greek physician Aretaeus vividly described the destructive nature of an illness which he named “diabetes,” derived from the Greek word “siphon” (meaning flowing through), and rendered the earliest account of diabetic patients’ intense thirst and “melting down of flesh and limbs into urine.” Diabetes indeed appears to have been a death sentence in the ancient era: Aretaeus did attempt to treat it, but could not provide a good prognosis. He commented that "life (with diabetes) is short, disgusting and painful.” In the Middle Ages, diabetes was known as the “pissing evil.” And until the 11th century, diabetes was commonly diagnosed by “water tasters,” who tasted the urine of people thought to have diabetes to see if the excretion was sweet like honey. Thus, the Latin word “mellitus,” meaning honey, was added to the term diabetes. As physicians learned more about diabetes, they began to understand how it could be managed. One of the first diabetes treatments involved prescribed exercise, often horseback rid Continue reading >>

Where did the word "diabetes" come from?

Origin of the term ‘diabetes’ The term diabetes is the shortened version of the full name diabetes mellitus. Diabetes mellitus is derived from the Greek word diabetes meaning siphon - to pass through and the Latin word mellitus meaning honeyed or sweet. This is because in diabetes excess sugar is found in blood as well as the urine. It was known in the 17th century as the “pissing evil”. The term diabetes was probably coined by Apollonius of Memphis around 250 BC. Diabetes is first recorded in English, in the form diabete, in a medical text written around 1425. It was in 1675 that Thomas Willis added the word “'mellitus'” to the word diabetes. This was because of the sweet taste of the urine. This sweet taste had been noticed in urine by the ancient Greeks, Chinese, Egyptians, Indians, and Persians as is evident from their literature. History of the treatment of diabetes Sushruta, Arataeus, and Thomas Willis were the early pioneers of the treatment of diabetes. Greek physicians prescribed exercise - preferably on horseback to alleviate excess urination. Some other forms of therapy applied to diabetes include wine, overfeeding to compensate for loss of fluid weight, starvation diet, etc. In 1776, Matthew Dobson confirmed that the sweet taste of urine of diabetics was due to excess of a kind of sugar in the urine and blood of people with diabetes. In ancient times and medieval ages diabetes was usually a death sentence. Aretaeus did attempt to treat it but could not give a good outcome. Sushruta (6th century BCE) an Indian healer identified diabetes and classified it as “Madhumeha”. Here the word “madhu” means honey and combined the term means sweet urine. The ancient Indians tested for diabetes by looking at whether ants were attracted to a person's u Continue reading >>

Who discovered the pancreatic extract?

Go to: The introduction of pancreatic extracts While Naunyn, Mering and Minkowski had focused on the pancreas as the seat of diabetes, Eugene Opie (1873–1971), a pathologist at Johns Hopkins University, Baltimore, made a further important advance by establishing the association between diabetes and destruction of the islets of Langerhans,10,11 and this observation stimulated research into the effects of administering pancreatic extracts. During the early 1900s in Aberdeen, Scotland, John Rennie and Thomas Fraser studied the effects in five patients with diabetes of giving an extract of “principal islets” (large islets forming separate globular aggregates made up mostly of endocrine pancreatic tissue present in some fishes (and snakes), but no convincing benefit was detected.12 At around the same time, in Belgium, J De Meyer (1878–1934) discovered an internal secretion produced by the islets,13,14 but his attempt to extract it from pancreatic tissue also failed. In Berlin, Georg Ludwig Zuelzer extracted animal pancreas with alcohol and saline, and, after first experimenting on rabbits, he gave injections of the extract to a dying diabetic patient. Although there seemed to be an initial improvement (no biochemical measurements were made), the extract was used up within a few days and the patient relapsed and died. He carried out further experiments,15 injecting five diabetic patients with pancreatic extract, but impurities caused fever. He spent a further three years trying to purify his extract. Zuelzer's method of extraction was subsequently developed by the pharmaceutical firm Hoechst and Zuelzer can justly be regarded as the first person to have achieved even partial success in finding a pancreatic extract with potential therapeutic value.16 Meanwhile, in Chic Continue reading >>

How to treat Type 1 diabetes?

Scientists at the University of Texas announced the breakthrough, which uses a novel approach that may eliminate Type 1 diabetes and see painful insulin injections become a thing of the past. University of Texas Health Science Center doctors used a virus as a carrier to introduce insulin-producing genes into the pancreas of rodent subjects. Professor Ralph DeFronzo said researchers altered cells so they secreted insulin, but only in response to glucose — mimicking the behavior of the body’s beta cells. This study bypasses the autoimmune system by altering other pancreatic cells so they can co-exist with immune defenses — unlike beta cells, which are rejected in Type 1 patients. At the moment, Type 1 diabetes is treated by monitoring glucose levels and injecting artificial insulin several times a day. While technology has made management of the condition easier, a cure has been elusive — until now. The patent’s co-inventor, Professor Bruno Doiron, said the results had never been seen before. “It worked perfectly,” Doiron said. “We cured mice for one year without any side effects.” Doiron predicted the same low-risk response in humans. “If a Type 1 diabetic has been living with these cells for 30, 40 or 50 years, and all we’re getting them to do is secrete insulin, we expect there to be no adverse immune response.” DeFronzo said the same method of treatment has been approved almost 50 times by the US Food and Drug Administration to treat various conditions, including rare childhood diseases. Whi Continue reading >>

Can dapagliflozin help with diabetes?

Researchers have discovered that a drug commonly used to treat type 2 diabetes patients could also benefit those with type 1 diabetes. A study by the University of Buffalo has revealed that type 1 patients given dapagliflozin - a medication traditionally given to type 2 sufferers - experienced a significant decline in their blood sugar levels. Until now, there hadn’t been a significant development in treatment for type 1 diabetes since the discovery of insulin in the 1920s. Both type 1 and type 2 diabetes sufferers have higher than normal blood sugar levels. When the drug was taken in addition to insulin - needed by type 1 diabetics every day to survive - there was an improvement in blood glucose levels. However, the former is where the body’s immune system attacks and destroys insulin-producing cells, while the latter is caused when the body doesn't produce enough insulin, or the body's cells don't react to insulin. In the study, researchers looked at 833 participants aged between 18 and 75 who had poorly controlled blood sugars for 24 weeks. It was the first time dapagliflozin had been tested for effectiveness and safety in treating type 1 globally - the study took place in 17 countries. When the drug was taken in addition to insulin - needed by type 1 diabetics every day to survive - there was an improvement in blood glucose levels. Fri, August 19, 2016 Diabetes is a common life-long health condition. There are 3.5 million people diagnosed with diabetes in the UK and an estimated 500,000 who are living undiagnosed with the condition. "Our paper provides the initial signal that dapagliflozin is safe and effective in patients with Type 1 diabetes and is a promising adjunct treatment to insulin to improve glycemic control," said Professor Paresh Dandona, a study aut Continue reading >>
