Nov 01, 2016  Latent autoimmune diabetes in adults (LADA) is considered a subgroup of type 1 diabetes and is often misdiagnosed because of a lack of both awareness and standardized diagnostic criteria (1–3). LADA is characterized by adult-onset diabetes and circulating autoimmune antibodies; thus, patients may present clinically with characteristics of both type 1 and type 2 diabetes (2–5). The Other Diabetes: LADA, or Type 1.5. And scientists have identified several other diabetes subtypes beyond types 1 and 2. The most common of these is called latent autoimmune diabetes in adults (LADA), and it accounts for roughly 10 percent of people with diabetes, making it probably more widespread than type 1. Answer From M. Regina Castro, M.D. Latent autoimmune diabetes in adults (LADA) is a slow progressing form of autoimmune diabetes. Like the autoimmune disease type 1 diabetes, LADA occurs because your pancreas stops producing adequate insulin, most likely from some 'insult' that slowly damages the insulin-producing cells in the pancreas.

She mainly studies the genetics of type 1 diabetes mellitus, with a particular focus on latent autoimmune diabetes in adults. Moreover, she is involved in research into the genetics of obesity and the identification of new markers of insulin resistance in children and adolescents who are overweight or have obesity. &. Ernesto Maddaloni, is a specialist in endocrinology and diabetes and a consultant endocrinologist at the University Campus Bio-Medico, Rome, Italy.

He qualified in medicine at the University Campus Bio-Medico and completed a postdoctoral research fellowship in the Research Division, Vascular Cell Biology Section, of the Joslin Diabetes Center (affiliated with Harvard Medical School) in Boston, Massachusetts, USA. His research activity has previously focused on the characterization of autoimmune diabetes during adulthood, contributing to the description of its epidemiology, and is now focused on the pathophysiology and clinical implications of vascular and bone complications. Adult-onset autoimmune diabetes is a heterogeneous disease that is characterized by a reduced genetic load, a less intensive autoimmune process and a mild metabolic decompensation at onset compared with young-onset type 1 diabetes mellitus (T1DM). The majority of patients with adult-onset autoimmune diabetes do not require insulin treatment for at least 6 months after diagnosis. Such patients are defined as having latent autoimmune diabetes in adults (LADA), which is distinct from classic adult-onset T1DM. The extensive heterogeneity of adult-onset autoimmune diabetes is apparent beyond the distinction between classic adult-onset T1DM and LADA. LADA is characterized by genetic, phenotypic and humoral heterogeneity, encompassing different degrees of insulin resistance and autoimmunity; this heterogeneity is probably a result of different pathological mechanisms, which have implications for treatment.

The existence of heterogeneous phenotypes in LADA makes it difficult to establish an a priori treatment algorithm, and therefore, a personalized medicine approach is required. In this Review, we discuss the current understanding and gaps in knowledge regarding the pathophysiology and clinical features of adult-onset autoimmune diabetes and highlight the similarities and differences with classic T1DM and type 2 diabetes mellitus.

Today, we know that younger people can get and that often appears in adulthood.

During pregnancy, women can get, which resembles type 2 and usually disappears after childbirth. And scientists have identified several other diabetes subtypes beyond types 1 and 2. The most common of these is called latent autoimmune diabetes in adults (LADA), and it accounts for roughly 10 percent of people with diabetes, making it probably more widespread than type 1.So why haven't more people heard of it? LADA can be classified as a more slowly progressing variation of type 1 diabetes, yet it is often misdiagnosed as type 2. As of now, there is still a lot of uncertainty over how exactly to define LADA, how it develops, and how important it is for patients to know if they have it. Surprise FindingDoctors stumbled upon the LADA phenomenon quite by accident back in the 1970s.

They were testing a way of identifying proteins called auto­antibodies in the blood of people with type 1. The presence of these proteins is evidence of an attack by one's own immune system. The new test was successful and confirmed for the first time that type 1 is an autoimmune disease in which the body's immune system kills off the beta cells in the pancreas, the makers of.As part of their study, the researchers also looked for the same autoantibodies in the general population and in people with type 2 diabetes (which is not an autoimmune disease). The proteins were virtually absent in the general population, but they showed up, to the scientists' surprise, in about 10 percent of people diagnosed with type 2. This suggested that there was a subcategory of people who could now be diagnosed as having LADA instead, even though there was no obvious difference in their symptoms from those of people with type 2.While not everyone has settled on calling the condition LADA (some prefer 'type 1.5'), or even whether it's distinct from type 1, researchers are working on a set of criteria for its diagnosis: 1) the presence of auto­antibodies in the blood, 2) adult age at onset, and 3) no need for insulin treatment in the first six months after diagnosis.

This definition would distinguish LADA from type 1—because people diagnosed with type 1 typically need to start insulin immediately—and from type 2, because of the presence of autoantibodies in the blood. There is still some controversy about whether these are the best criteria for diagnosing LADA. But 'the general concept is very well accepted,' says Jerry Palmer, MD, a professor at the University of Washington in Seattle.The debate over LADA has led some doctors to move away from the idea that the various types of diabetes are truly separate entities. 'We think there is a continuum in diabetes overall,' says Suat Simsek, MD, a professor at VU University Medical Center in the Netherlands. Autoantibodies and their effect on beta cell health may be the key to defining the relationships among type 1, type 2, and LADA. Scientists have discovered several different types of auto­antibodies related to diabetes.

People with type 1 have higher levels and more types of these proteins than do those with LADA, which may be the reason beta cells are destroyed faster in type 1 than in LADA. In type 2 diabetes, autoantibodies are generally absent and, as a consequence, beta cell decline is the slowest.There was some hope that genetics would help to draw the diabetes boundaries. But a 2008 study in Diabetes found that, genetically, LADA has features of both type 1 and type 2. So, in autoantibodies and genetics, LADA appears to fall somewhere between types 1 and 2 on the diabetes spectrum, though perhaps closer to type 1. Does It Matter?Sorting out the different types and subtypes of diabetes satisfies scientific curiosity, but is there good reason to look for LADA?

Would it help health care providers to give better treatment or people with diabetes to achieve better blood glucose control and fewer complications?Blood tests for LADA measure autoantibodies and insulin production, but they may not be necessary for most people diagnosed with type 2, according to Simsek. In a severely obese person (with a body mass index of 35 or more), 'it doesn't make sense to test,' he says, in part because treatment for LADA wouldn't really be different from that of someone with type 2: diet, exercise, and, if necessary, medication. But testing could be a good idea for leaner, physically active adults who are more likely to have LADA and should not be overly, a characteristic of type 2.One potentially critical reason to test for LADA is that, someday, the results may help tailor treatment. For people with LADA, there is already some evidence that early insulin treatment may keep beta cells in the business of producing insulin, at least for a while. A 2008 Japanese study in the Journal of Clinical Endocrinology & Metabolism compared insulin and sulfonylurea treatment in 4,000 adults with LADA. Treating people early with insulin helped them avoid total dependence on insulin longer than those who took sulfonylureas.'

Insulin treatment can preserve beta cell function,' says principal investigator Tetsuro Kobayashi, MD, PhD, a professor at the University of Yamanashi in Japan. 'If you use other oral agents, you lose function faster and go to an insulin-dependent state very, very quickly.' So, for people with LADA, a misdiagnosis of type 2 may mean that they both take ineffective oral medications and lose their insulin-producing beta cells faster.Another reason to test is that medicines being developed to prevent or cure type 1 diabetes may also turn out to be effective against LADA.

'What we need is another therapy besides insulin, one that alters the underlying disease process,' says Palmer. 'Then it will be of prime importance whether or not you have LADA.

But right now we don't have that therapy.' If such a therapy does emerge, the hope is that by then LADA will be better understood and more accurately diagnosed, so that people with this form of diabetes can get the treatment they need.Also.
