Research Design And Methods

Living with latent autoimmune diabetes in adults (LADA) | Charlies story | Diabetes UK

We included 64 glutamic acid decarboxylase antibody-positive individuals, who were diagnosed with diabetes < 3âyears before the study, aged 30 to 70âyears, and without clinical need for insulin treatment. We stratified participants by age and body mass index and evaluated β-cell function by GSCT after a 48-hour temporary withdrawal of study medication.

Presence Of Other Autoimmune Conditions

Positive pancreatic autoantibodies are strongly associated with other autoimmune diseases, particularly thyroid disease . There is also an association with coeliac disease . A personal or family history of other autoimmune disease is another useful clue when considering LADA.

Screening for LADA

In view of the relatively high prevalence seen in studies , it can be argued that there is value in screening all adults with a new diagnosis of diabetes for autoantibodies. Knowing that someone is antibody-positive will alert clinicians to the possibility of a more rapid progression towards insulin and affect our monitoring and treatment choices .

In the Consensus Statement, the panel concluded that general screening for autoantibodies should be used in newly diagnosed, non-insulin-requiring diabetes, and that the one-off cost associated with this test would be justified . They recommended testing for anti-GAD antibodies, which are the most sensitive marker of LADA and most widely used across the world .

Clinical Heterogeneity Of Lada

At diagnosis, the clinical presentation of autoimmune diabetes is extremely broad, ranging from diabetic ketoacidosis to hyperglycemia controlled with diet alone or hypoglycemic agents. In this context, subjects defined as having LADA who do not require insulin at first, encompass a wide spectrum of phenotypes from prevalent insulin resistance to prevalent insulin deficiency, sharing halfway clinical and metabolic features of T1DM and T2DM . By comparing patients with T2DM with those affected by LADA, the latter tend to show fewer signs of metabolic syndrome, such as healthier lipid and blood pressure profiles, lower BMI and waist-to-hip ratio . In this regard, the A Diabetes Outcome Progression Trial found that among recently diagnosed individuals with T2DM, those who were positive for GADA had higher high-density lipoprotein cholesterol and lower triglyceride levels, as well as lower frequency of metabolic syndrome . By contrast, the majority of studies reported that the features of metabolic syndrome appear to be more prevalent in LADA than in classical T1DM.

Interventions For Latent Autoimmune Diabetes In Adults

LADA is a condition that at diagnosis looks like type 2 diabetes but actually is a type 1 diabetes, where the patient will become insulin requiring. In the UK approximately 3.6% of people who look like they have type 2 diabetes actually have type 1 diabetes, while other studies suggest the prevalence is higher and treatment for these patients may need to be different from that used in type 2 diabetes.We identified 15 publications looking at 1019 patients who were followed between three months to 10 years. We found many of the publications had poor quality of reporting and had small numbers of participants. However, there does seem to be evidence from this review that the drug sulphonylurea could make patients insulin dependent sooner and it does not control blood sugar as well as insulin. Therefore, this suggests that this drug should not be a first line treatment for patients with LADA. In addition, insulin combined with vitamin D, or Chinese herbs may maintain natural insulin production better than insulin alone. Similarly, glutamic acid decarboxylase may maintain natural insulin production. However, there was no conclusive evidence that any of the other remaining treatment methods were better than each other. Studies on oral agents or insulin reported no adverse events in terms of severe hypoglycaemic attacks.

Lada And Diagnostic Challenges

Education in Nutrition News

To identify patients affected by LADA, islet autoantibodies should be theoretically tested in all cases of newly diagnosis T2DM. In fact, the early identification of LADA as well as a personalized therapeutic approach might be essential in order to slow down the autoimmunity process and preserve -cell function.

Latent Autoimmune Diabetes In Adults: Causes Symptoms Treatment

An autoimmune disorder is a condition in which the immune system of a personmalfunctions. Usually, for a healthy individual when foreign cells like bacteria orviruses try to get inside the body, the immune system sends out fighter cells todestroy them. The immune system of a person with an autoimmune disordercannot differentiate these foreign invaders and host cells apart. This results inthe fighter cells sent by the immune system attacking the host cells intending todestroy them. It is caused by abnormally low or high activity of the immunesystem. These attacks can affect any part of the body and result in weak bodyfunctioning.

Q: What is latent autoimmune diabetes in adults ?

A: In LADA, patients appear to have type 2 diabetes phenotypically. They do not, however, have an early requirement for insulin. They are also positive for autoantibodies usually associated with type 1 diabetes. When compared to those with type 1 diabetes, these patients generally have greater preservation of ß-cell function with a slower development of absolute insulin deficiency however, they do invariably develop a need for insulin.1

The proposed diagnostic criteria for LADA include:

1) Adult age at diagnosis .

2) Positivity for at least one antibody usually seen in type 1 diabetes including islet cell autoantigen-2 antibodies, islet cell antibodies, insulin antibodies, and glutamic acid decarboxylase 65 antibodies .

3) Evidence of at least temporary preservation of ß-cells with a delay in the need for insulin therapy at least 6 months after initial diagnosis.2 These patients usually will require insulin within 6 years of diagnosis as ß-cells fail with the autoimmune pancreatic effects.

Q: Should I check antibody levels on all new onset adult patients with diabetes to evaluate for the presence of LADA?

Q: Are there any distinguishing clinical features in patients with LADA versus type 2 diabetes?

What Are The Symptoms Of Mody

Symptoms can vary and depend on which gene mutation is causing your MODY.

In general, the symptoms of MODY are mild and show up gradually. That’s why many people first learn they have it when a routine blood test shows they have abnormal blood sugar levels.

If you do have symptoms, they’ll be the same as those for other types of diabetes, such as:

  • Greater thirst
  • Frequent infections

How Is Mody Treated

Your treatment options for MODY, and how well they’re likely to work, depend on which genetic mutation is causing your disease. Doctors treat most forms of MODY with a type of oral diabetes drug called sulfonylureas. These drugs help your pancreas make more insulin.

Depending on the type of MODY you have, you may need injections of insulin. Some people are able to manage their condition with lifestyle changes like diet and exercise.

Type 15 Diabetes Outlook

Life expectancy for people who have LADA is similar to people who have other types of diabetes. Higher blood sugar over a sustained period of time can lead to diabetes complications , such as kidney disease, cardiovascular problems, eye disease, and neuropathy, which can adversely affect prognosis. But with good blood sugar control, many of these complications can be prevented.

In the past, people who had type 1 diabetes had a shortened life expectancy . But improved diabetes treatments are changing that statistic. With good blood sugar control, a normal life expectancy is possible.

How Is Lada Different From Type 1 Diabetes

  • The process of destruction of the pancreatic beta cells in the case of LADA is slow and can last up to several years. In type 1 diabetes, it is rapid and the full-blown disease develops within a few weeks, up to several months.
  • Type 1 diabetes always has severe symptoms. However, the form of diabetes known as LADA can be asymptomatic for a very long time because it is usually accompanied by slight or moderate hyperglycemia.
  • LADA is diagnosed in adult patients, usually between 35 and 50 years of age, although, it may also occur in older people. Type 1 diabetes is diagnosed mainly in children, adolescents and young adults.

Inclusion And Exclusion Criteria

Men and women, aged 30 to 75âyears, positive for GAD antibodies with < 3 years of known diabetes, without pharmacological treatment for diabetes and with no clinical need for insulin treatment were eligible for the study. Glycated haemoglobin concentration had to be at least 10% above the upper limit of normal before treatment, or 5% above the ULN when on treatment with metformin, but not exceeding 60% above the ULN at the time of randomization. Fasting levels of C-peptide had to be â¥0.3 nmol/L.

Exclusion criteria were kidney failure , proliferative retinopathy with or without sequelae, myocardial infarction , unstable angina pectoris and other serious chronic diseases . We also excluded fertile women who planned to become pregnant during the study period.

Types Of Testing To Diagnose Lada

There are a variety of blood tests that can rule out type 2 diabetes and confirm a LADA diagnosis. But the two tests that offer the clearest and most immediate diagnosis of LADA are:

  • Glutamic acid decarboxylase
  • Islet cell antibodies

GAD and ICA testing is looking for autoantibodieswhich are the result of your immune system attacking the cells in your pancreas that produce insulin. A person with type 2 diabetes would not test positive for these autoantibodies.

While autoantibody testing should be adequate for a LADA diagnosis, other testing can include:

  • Hemoglobin A1c test
  • Fasting plasma glucose test
  • Oral glucose tolerance test
  • Random plasma glucose test
  • Ketone test

While this list can feel overwhelming, the first two tests should lead your healthcare team to a clear diagnosis very quickly.

How Can We Distinguish Between Lada And Type 2 Diabetes

What is LADA? (Malayalam) | Dr. Pratibha Prasannan
  • Although hyperglycemia in both LADA and type 2 diabetes increases slowly, it is the result of completely different causes. In the first case it is an autoimmune process, in which the cells producing insulin are slowly destroyed, in the second, insulin resistance occurs.
  • LADA is most often diagnosed in people with a normal body weight or in those who are slightly overweight, who do not have hypertension, lipid disorders or a genetic susceptibility towards diabetes.
  • LADA often appears as another autoimmune disease .

Diagnostic Challenges in LADA

The panel agreed that to effectively identify patients affected by LADA, all newly diagnosed T2D patients should be screened for GADA positivity to allow for a rapid diagnosis and implementation of an appropriate therapy and follow-up of progressing -cell failure. This approach may be costly, but the one-off cost of GADA measurement is justified.

As they become available, new cost-effective bioassays detecting autoantibodies targeting other islet autoantigens should be considered to diagnose LADA. If, however, economic issues represent an obstacle, at least one of the following clinical factors should be sought to select patients in whom to measure GADA: family history of T1D or autoimmune diseases , normal/slightly overweight BMI , young age at onset , and poor metabolic control. If patients are GADA positive, they are managed according to . If there is a strong suspicion of LADA in a GADA-negative individual, other islet autoantibodies should be assayed. GADA-negative , likely T2D, patients are managed according to . Although elevated levels of GADA have been associated with a greater risk of insulin requirement compared with low levels, GADA levels cannot be used in clinical practice for therapeutic choice because it is difficult to set a threshold to discriminate between high and low levels, bioassays are semiquantitative, and there is variation in GADA levels between different laboratories.

Fatty Fish Consumption And Risk Of Latent Autoimmune Diabetes In Adults

It has been suggested that intake of fatty fish may protect against both type 1 and type 2 diabetes. Hypotheses rest on the high marine omega-3 fatty acid eicosapentaenoic acid+docosahexaenoic acid and vitamin D contents, with possible beneficial effects on immune function and glucose metabolism. Our aim was to investigate, for the first time, fatty fish consumption in relation to the risk of latent autoimmune diabetes in adults . Analyses were based on data from a Swedish casecontrol study with incident cases of LADA and type 2 diabetes and randomly selected diabetes-free controls . Diabetes classification was based on the onset of age , glutamic acid decarboxylase autoantibodies, and C-peptide. A validated food frequency questionnaire was used to derive information on previous intake of fish, polyunsaturated long-chain omega-3 fatty acids and supplementation of fish oil and vitamin D. Odds ratios with 95% confidence intervals were calculated using logistic regression, adjusted for age, gender, body mass index , family history of diabetes, physical activity, smoking, education, and consumption of alcohol, fruit, vegetables and red meat. Weekly fatty fish consumption , was associated with a reduced risk of LADA but not type 2 diabetes . Similar associations were seen for estimated intake of n-3 PUFA and fish oil supplementation . Our findings suggest that fatty fish consumption may reduce the risk of LADA, possibly tContinue reading > >

Enhancing Healthcare Team Outcomes

According to the World Health Organization , there were 422 million people with DM globally. As the prevalence of LADA in a population of T2 DM is between 4 and 12 percent depending on the population, between 17 to 50 million will have LADA. This number is likely to grow exponentially in the coming years.

The primary care practitioner is very likely to encounter patients with LADA frequently and should be equipped with the knowledge and understanding to recognize and manage this condition promptly.

The endocrinologist sees difficult and complex patients and coordinates care with the PCP, ophthalmologist, podiatrist, and geneticist.

Laboratory medicine advises on the appropriateness of tests, performs biochemical and serological tests, and communicates them to the treating physician on time.

Bariatric surgeons must have a high index of suspicion for LADA in the obese with diabetes and counsel them regarding the less than optimal glycemic control post-surgery.

A coordinated effort by all the above health care providers is needed to achieve good glycemic control, prevent or delay complications, and substantially reduce morbidity, mortality, and health care costs.

Absence Of Metabolic Syndrome

Lada Diabetes Symptoms

Metabolic syndrome is the combination of central obesity, hyperlipidaemia, hypertension and insulin resistance. People with LADA are more likely to have metabolic syndrome than people with type 1 diabetes, but less likely than those with antibody-negative type 2 diabetes .

In clinical practice, a person diagnosed with type 2 diabetes who has a normal BMI with no features of metabolic syndrome is a good clue for the possible presence of autoantibodies and, potentially, a LADA diagnosis. Of course, this is not always true, and some cases may be indistinguishable from type 2 diabetes with metabolic syndrome .
