Poor Specificity Of Low Growth Hormone And Cortisol Levels During Fasting Hypoglycemia For The Diagnoses Of Growth Hormone Deficiency And Adrenal Insufficiency

Poor Specificity Of Low Growth Hormone And Cortisol Levels During Fasting Hypoglycemia For The Diagnoses Of Growth Hormone Deficiency And Adrenal Insufficiency

Abstract OBJECTIVES. Fasting tests are used to identify the cause of hypoglycemia in children. The purposes of this study were to (1) determine whether growth hormone and cortisol levels obtained at the time of hypoglycemia in such tests can identify children with growth hormone and/or cortisol deficiency and (2) identify potential clinical factors that influence growth hormone and cortisol responses to hypoglycemia. STUDY DESIGN. The design consisted of chart review of all diagnostic fasting tests conducted over a 3-year period (n = 151). A normal growth hormone level was defined as ≥7.5 ng/mL, and a normal cortisol level was defined as ≥18 μg/dL. RESULTS. During the fasting tests, 84 children (median age: 1.3 years [2 days to 14.3 years]), became hypoglycemic, with blood glucose ≤50 mg/dL. Diagnoses included normal, ketotic hypoglycemia, hyperinsulinism, fatty acid–oxidation defects, glycogen-storage disease, and late dumping hypoglycemia. A total of 70% had growth hormone and cortisol levels less than the “normal” thresholds regardless of diagnosis. Of various factors (age, diagnosis, fast duration, duration blood glucose level of <60 mg/dL, and blood glucose nadir), only age was positively associated with cortisol, and none were consistently related to growth hormone. CONCLUSIONS. A singe low growth hormone or cortisol value at the time of fasting hypoglycemia has poor specificity for the respective diagnoses of growth hormone deficiency and adrenal insufficiency. Abstract OBJECTIVE. A high proportion of children in the United States are overweight, suffer from food insecurity, and live in households facing maternal stressors. The objective of this article was to identify the associations of food insecurity and maternal stressors with childhood overweig Continue reading >>

The Theory.

Tell me who this sounds like: The typical patient with ketotic hypoglycemia is a "toddler", a young child between the ages of 10 months and 4 years. Episodes nearly always occur in the morning after an overnight fast, often longer than usual. Symptoms include those of neuroglycopenia, ketosis, or both. The neuroglycopenic symptoms usually include lethargy and malaise, but may include unresponsiveness or seizures. The principal symptoms of ketosis are anorexia, abdominal discomfort, and nausea, sometimes progressing to vomiting. If severe, parents usually take the child to a local emergency department, where blood is drawn. The glucose is usually found to be between 35 and 60 mg/dl (1.8-3.1 mMol/L). The total CO2 is usually somewhat low as well, (14-19 mMol/L is typical), and if urine is obtained, high levels of ketones are discovered. Ketones can also be measured in the blood at the bedside (Medisense glucometer). Other routine tests are normal. If given intravenous fluids with saline and dextrose, the child improves dramatically and is usually restored to normal health within a few hours. A first episode is usually attributed to a "viral infection" or acute gastroenteritis. However, in most of these children one or more additional episodes recur over next few years and become immediately recognizable to the parents. In mild cases, carbohydrates and a few hours of sleep will be enough to end the symptoms. Precipitating factors, conditions that trigger an episode, may include extended fasting (e.g., missing supper the night before), a low carbohydrate intake the previous day (e.g., a hot dog without a bun), or a stress such as a viral infection. Most children affected by ketotic hypoglycemia have a slender build, many with a weight percentile below height percentile, tho Continue reading >>

Hypoglycemia

Hypoglycemia refers to low blood sugar, or technically a lower than normal blood glucose level. It is rarely encountered in pediatric practice outside of the newborn nursery, where it is a commonplace event. Profound hypoglycemia in the newborn can cause brain damage. Aggressive blood glucose monitoring of asymptomatic (nothing appears to be wrong) infants has been the standard. I think attitudes are softening in the era of cost-benefit analysis, since many babies seem to be subjected to large numbers of (in retrospect) needless blood glucose determinations compared to the actual number of significant problems identified. Symptoms of hypoglycemia are generally related to the body's efforts to raise the blood glucose level back to where it should be. These symptoms are really just the manifestations of adrenaline (epinephrine) release, which is the chief signal the body uses to mobilise stored glucose into the bloodstream. The most noticable adrenaline effects are nervousness, light-headedness, increased heart rate, and a particularly urgent sense of hunger. Headache is sometimes a symptom of hypoglycemia; I believe the explanation is brain neuronal cell dysfunction. In the newborn, symptoms of hypoglycemia include sweating, jitteriness, rapid breathing, rapid heart rate, pallor, or even apnea. Profound or very difficult to treat hypoglycemia in a newborn can signal the presence of rare but dangerous conditions such as galactosemia, growth hormone deficiency, insulin secreting tumors, or may reflect severe intrauterine growth restriction (IUGR). Hypoglycemia is the opposite of hyperglycemia - high blood glucose - which is the hallmark of diabetes. True hypoglycemia in children older than newborns is reasonably rare and is not the cause of the myriad complaints and condit Continue reading >>

Hypoglycemia in Infants and Children Authors: Robert A. Felter, MD, FAAP, CPE, FACPE, Professor of Clinical Pediatrics, Georgetown University School of Medicine; Assistant Director, Pediatric Inpatient and Emergency Service, Inova Loudoun Hospital, Leesburg, VA. Ron D.

Peer Reviewer: Ademola Adewale, MD, FAAEM, Assistant Professor of Emergency Medicine, Assistant Program Director, Florida Hospital Emergency Medicine Residency Program, Orlando, FL. Hypoglycemia is the most common metabolic disorder in children. The causes for hypoglycemia are many and diverse.1 One of the most frequent causes of hypoglycemia is insulin/glucose imbalance in diabetic children; since the management of diabetes and its complications is a subject on its own, this topic will not be included in this issue. The authors focus on issues important to the emergency physician, with emphasis on the need to diagnose and treat hypoglycemia quickly. In the very young infant, failure to recognize and treat hypoglycemia may lead to permanent neurological sequelae. It is also important to remember that hypoglycemia is a symptom and not a diagnosis or a disease entity and always has an underlying etiology that must be ascertained. Sometimes the emergency department (ED) physician may determine the underlying cause, and sometimes the symptom must be treated without knowing the underlying cause. Because hypoglycemia can be rapidly and easily determined at the bedside, there is little reason not to obtain this important piece of clinical information.

Practical Peds: Handling The Hypoglycemic Child

Practical Peds: Handling The Hypoglycemic Child

There are a few kids out there who are prone to hypoglycemia. They may be diabetic and on insulin, or have ketotic hypoglycemia or metabolic disorders that cause them to drop their blood sugars with stress. One thing that mothers can do is stock up on cake frosting. Your next patient is a small five-year-old boy who is rather thin and pale. He is lying on the gurney and not responding to anything. On rapid assessment, his airway, breathing and circulation seem to be OK. He isn’t actively having a seizure. His mom says she brought him in because his blood sugar is low. You get a bedside glucose and she’s right, it’s 38. You start a line and grab a couple of tubes of blood before you start any dextrose. You bolus him with 5 ml/kg of 10% dextrose rapidly through the peripheral line. Now it’s time to talk to the mom and get more of the story. She says he’s had this problem since he was two. He’ll have episodes of vomiting and become unresponsive and when he’s taken in to the ED his blood sugar will be low. He’s been admitted for this in the past but his work-up has been inconclusive. Mom says that she was to tell the ED the next time he came in to get some labs before they give him glucose. OK, now you’re feeling pretty good about those tubes you snagged. This morning was a pretty typical episode for him. He woke up and began vomiting. No fevers. Mom gave him Zofran but he vomited that too. She kept checking his blood sugars and they ranged from 49-59. She made one more attempt to get him to take something by mouth but he threw that up too, so she loaded him in the car and brought him in to the ED. He’s vomited about 8 times. No diarrhea, no fevers, no ill contacts. His past history is otherwise unremarkable. He’s on no meds except Zofran as needed. No Continue reading >>

Ketotic Hypoglycemia In Children

Ketotic Hypoglycemia In Children

Did You Know? Fasting tolerance improves with an increase in body mass, which is believed to be the reason why children with ketotic hypoglycemia outgrow this condition by the time they turn 8 to 9 years old. Ketotic hypoglycemia is the most common type of hypoglycemia that affects children after the neonatal period. However, the condition resolves on its own by the time they reach adolescence. More commonly, children in the age group of 18 months to 5 years experience recurrent episodes of hypoglycemia, especially during an illness or after fasting for a prolonged time period (more than 8 to 16 hours). Hypoglycemia refers to a blood sugar level lower than 70 mg/dL. Usually, hypoglycemia is a complication associated with diabetes. So, diabetic children and adolescents can experience hypoglycemia when they take too much of insulin or eat too little. But, ketotic hypoglycemia has not been found to be related to a specific endocrine or metabolic abnormality. It is mainly associated with low tolerance for fasting, and most children outgrow this condition before they turn 8 to 9 years old. After this age, the incidence of this type of hypoglycemia is quite rare. It is characterized by fasting hypoglycemia and ketosis. Ketosis refers to an increase in the level of ketones in the body. When the level of blood glucose is low, the liver releases its stored glycogen, which is converted to glucose in order to maintain adequate serum glucose. This is then followed by lipolysis, where the fat is broken down by the body to derive energy. The process, however, produces ketones as by-products. So, this condition is where the blood glucose level is low, with elevated levels of ketone bodies. ✦ Ketotic hypoglycemia, also known as 'accelerated starvation', is idiopathic in nature.

Question: From Moraga, California, USA: My daughter was diagnosed with ketotic hypoglycemia at two years, 10 months after a bout of rotavirus. She has consistently been in the 75th percentile for height and 90th percentile for weight, so she does not appear to fit the standard child with ketotic hypoglycemia I have read about. The episode occurred after a trip to a high altitude where she was extremely active (we live at sea level). She started vomiting at 2 a.m. one night during our vacation and could hold nothing down the entire next day, not even a teaspoon of water. We drove home and took her to the Emergency Room (ER) almost 24 hours after the vomiting started. The doctor gave her suppositories to stop the vomiting, but performed no blood work, and we went home. She drank some Pedialyte and juice, about 16 ounces total, through the night and next morning. Around noon, she started vomiting again and could hold nothing down. Mild diarrhea also started. She became more lethargic and that night, around 2 a.m. (48 hours after the vomiting started and 24 hours after the first visit), she started vomiting bile. We took her back to the ER. Her sugar was 26 mg/dl [1.4 mmol/L]. It took a few hours for her sugar to get back over 80 mg/dl [4.4 mmol/L], where they wanted it. She was hospitalized and the doctors performed numerous tests on her, including a fasting blood sugar test, and found nothing out of the ordinary aside from the rotavirus. We saw an endocrinologist who had us test her blood sugar at home for a few weeks. Everything looked okay and we were told she had ketotic hypoglycemia. We just had to be careful to give her something to eat before bed and an early breakfast, which we do. Aside from getting grumpy when hungry, she has been fine since the episode a little Continue reading >>

Low Blood Sugar In Kids Linked To Mutations

Low Blood Sugar In Kids Linked To Mutations

WASHINGTON -- Children with recurrent unexplained episodes of hypoglycemia should be screened for the ketotic forms of glycogen storage disease, a researcher said here. Among a group of 173 children who had two or more episodes of ketotic hypoglycemia, defined as plasma glucose levels below 50 mg/dL and ketones present in the urine or blood, 34.7% were found on genetic testing to have mutations associated with disorders of glycogen storage or utilization, according to Michelle M. Corrado, BS, and colleagues from the University of Florida in Gainesville. Type 1, or "classical" glycogen storage disease, is caused by a genetic mutation which causes a deficiency of glucose-6-phosphatase. The result is an inability to metabolize glucose accompanied by a lack of gluconeogenesis, so patients become severely hypoglycemic and develop hepatomegaly. Certain other forms of the disease, however, are characterized by a milder phenotype. In types 3,6, and 9, the mutations prevent glycogen from breaking down into glucose, while in type zero, the mutation inhibits storage of glucose in the liver as glycogen. In those four types, patients can't utilize glucose for energy, but glyconeogenesis is intact and patients can break down fat for energy, with byproducts of triglycerides and ketones. Because little is known about the prevalence of these conditions, and to determine whether they might be an underrecognized cause of childhood hypoglycemia, Corrado's group has conducted a long-term study in which they screened genomic DNA from saliva of children with multiple episodes of hypoglycemia and no evidence of adrenal insufficiency, growth hormone deficiency, or fatty acid oxidation disorders. A total of 102 of the children enrolled in the study between 1998 and 2013 were male, and 71 were fe Continue reading >>

Hypoglycemia In Children

Hypoglycemia In Children

What is hypoglycemia? Hypoglycemia occurs when the blood sugar is too low to fuel the brain and the body. Glucose is the main source of fuel for the body. The normal range of blood sugar, depending on the timing and nutritional content of the last meal consumed, is approximately 70 to 140 mg/dl (milligrams of glucose per deciliter of blood). If you have type 1 diabetes, your goal blood sugar range may be slightly different. Infants and small children with type 1 diabetes will have different goal ranges than adolescents or adults. However, consult your child's doctor for more specific information. Hypoglycemia may be a condition by itself, or may be a complication of diabetes or another disorder. Hypoglycemia is most often seen as a complication of overdoing insulin in a person with diabetes, which is sometimes referred to as an insulin reaction. What causes hypoglycemia? Causes of hypoglycemia in children with diabetes may include the following: Too much medication; for instance, too much insulin or oral diabetes medication Medication mistakes. All families will, at some point, give the wrong kind of insulin for a meal or at bedtime. Inaccurate blood-glucose readings A missed meal A delayed meal Too little food eaten, as compared to the amount of insulin taken More exercise than usual Diarrhea or vomiting Injury, illness, infection, or emotional stress Other medical problems sometimes seen in people with type 1 diabetes, such as celiac disease or an adrenal problem. An additional cause of hypoglycemia in neonates and toddlers includes a group of conditions called hyperinsulinism. This may occur as a result of abnormal cell development of the special "beta" cells in the pancreas that secrete insulin or from a mass in the pancreas. Hypoglycemia due to endogenous insulin i Continue reading >>

Missed Meals Or Night Hunger Can Make Your Child Throw Up

Missed Meals Or Night Hunger Can Make Your Child Throw Up

IN MOST cases, we have seen young kids who go to bed or sleep without super and in the night complains of nausea or vomit. When we eat, food, especially carbohydrates, are converted into glucose in the body that provides energy. Glucose in blood is glycemia and in case there is low glucose, then the situation becomes hypoglycemia. The situation whereby kids develop low blood glucose or hypoglycemia and vomit is known as ketotic hypoglycemia. Some parents might not realise that not getting enough food can be the cause of unexplained vomiting for their young ones and this usually happens in the middle of the night or morning. Children who are seemingly health and vomit during the above mentioned times then vomiting is often caused by low blood sugar. However, this problem is often seen amongst children aged nine months and five years. The child will typically feel some nausea or abdominal discomfort just prior to vomiting, and will usually be subdued for about 30 minutes after vomiting, afterwards will otherwise appear normal. Vomiting caused by ketotic hypoglycemia is often misdiagnosed as the stomach flu. The distinguishing feature of ketotic hypoglycemia is that the child quickly returns to normal; if vomiting occurs in the middle of the night, after a short period of general weakness, the child will typically sleep comfortably for the rest of the night. But if vomiting occurs in the morning, the child has to eat before he or she goes for daily activities. Vomits caused by ketotic hypoglycemia differ from those caused by other problems such as the stomach flu. In ketotic hypoglycemia, the Vomitus appears typically bubbly and tinged with a bit of yellow color whereas in stomach flu the vomits are incompletely digested food. Why so common in the middle of the night? Duri Continue reading >>

What are the symptoms of hypoglycemia? While each child may experience symptoms of hypoglycemia differently, the most common include: shakiness dizziness sweating hunger headache irritability pale skin color sudden moodiness or behavior changes, such as crying for no apparent reason clumsy or jerky movements difficulty paying attention or confusion What causes hypoglycemia? The vast majority of episodes of hypoglycemia in children and adolescents occur when a child with diabetes takes too much insulin, eats too little, or exercises strenuously or for a prolonged period of time. For young children who do not have diabetes, hypoglycemia may be caused by: Single episodes: Stomach flu, or another illness that may cause them to not eat enough fasting for a prolonged period of time prolonged strenuous exercise and lack of food Recurrent episodes: accelerated starvation, also known as “ketotic hypoglycemia,” a tendency for children without diabetes, or any other known cause of hypoglycemia, to experience repeated hypoglycemic episodes. medications your child may be taking a congenital (present at birth) error in metabolism or unusual disorder such as hypopituitarism or hyperinsulinism.

Ketotic Hypoglycemia

Ketotic Hypoglycemia

Ketotic hypoglycemia is a medical term used in two ways: (1) broadly, to refer to any circumstance in which low blood glucose is accompanied by ketosis, and (2) in a much more restrictive way to refer to recurrent episodes of hypoglycemic symptoms with ketosis and, often, vomiting, in young children. The first usage refers to a pair of metabolic states (hypoglycemia plus ketosis) that can have many causes, while the second usage refers to a specific "disease" called ketotic hypoglycemia. Hypoglycemia with ketosis: the broad sense[edit] There are hundreds of causes of hypoglycemia. Normally, the defensive, physiological response to a falling blood glucose is reduction of insulin secretion to undetectable levels, and release of glucagon, adrenaline, and other counterregulatory hormones. This shift of hormones initiates glycogenolysis and gluconeogenesis in the liver, and lipolysis in adipose tissue. Lipids are metabolized to triglycerides, in turn to fatty acids, which are transformed in the mitochondria of liver and kidney cells to the ketone bodies— acetoacetate, beta-hydroxybutyrate, and acetone. Ketones can be used by the brain as an alternate fuel when glucose is scarce. A high level of ketones in the blood, ketosis, is thus a normal response to hypoglycemia in healthy people of all ages. The presence or absence of ketosis is therefore an important clue to the cause of hypoglycemia in an individual patient. Absence of ketosis ("nonketotic hypoglycemia") most often indicates excessive insulin as the cause of the hypoglycemia. Less commonly, it may indicate a fatty acid oxidation disorder. Ketotic hypoglycemia in Glycogen storage disease[edit] Some of the subtypes of Glycogen storage disease show ketotic hypoglycemia after fasting periods. Especially Glycogen storage Continue reading >>

No matter what we're doing, even during sleep, our brains depend on glucose to function. Glucose is a sugar that comes from food, and it's also formed and stored inside the body. It's the main source of energy for the body's cells and is carried to them through the bloodstream. When blood glucose levels (also called blood sugar levels) drop too low, it's called hypoglycemia. Very low blood sugar levels can cause severe symptoms that need immediate medical treatment. Blood sugar levels in someone with diabetes are considered low when they fall below the target range. A blood sugar level slightly lower than the target range might not cause symptoms, but repeated low levels could require a change in the treatment plan to help avoid problems. The diabetes health care team will find a child's target blood sugar levels based on things like the child's age, ability to recognize hypoglycemia symptoms, and the goals of the diabetes treatment plan. Low blood sugar levels are fairly common in people with diabetes. A major goal of diabetes care is to keep blood sugar levels from getting or staying too high to prevent both short- and long-term health problems. To do this, people with diabetes may use insulin and/or pills, depending on the type of diabetes they have. These medicines usually help keep blood sugar levels in a healthy range, but in certain situations, might make them drop too low. Hypoglycemia can happen at any time in people taking blood sugar-lowering medicines, but is more likely if someone: skips or delays meals or snacks or doesn't eat as much carbohydrate-containing food as expected when taking the diabetes medicine. This is common in kids who develop an illness (such as a stomach virus) that causes loss of appetite, nausea, or vomiting. takes too much insulin, ta Continue reading >>

First Blog Ever, First Ketotic Hypoglycemic Event Ever...

First Blog Ever, First Ketotic Hypoglycemic Event Ever...

Hi everyone, if there is anyone out there? I am starting up a blog to help provide tips, tricks and advice for those out there who have toddlers with Ketotic Hypoglycemia. My 3 year old son was diagnosed with this condition last weekend. I have yet to find very handy resources for this condition, so I thought it best to start chronicling, not only for myself, but others out there that might find some of this useful. Last Saturday our son woke up quite lethargic, requested and started chugging water (a first), and over a 45 minute period he became virtually unresponsive. His lips were the color of his skin, he was a limp noodle and was sweating profusely. This was all a first. Was he dehydrated? Something was seriously wrong. We could hardly keep him awake. We rushed him to our Doctor's office, luckily right around the corner and open on a Saturday.... Thankfully, the Doc knew immediately to check his blood sugar. His sugar was at a very scary level of 22, and we later learned he was minutes away from seizure! Thankfully, he never had one, or I would have likely had one with him! She was shocked he was even awake (barely). Normal blood sugar levels for a child his age are, ideally, 80 - 150. Most people pass out when they get below 50. The Doc gave him a sugary glucose drink used in diabetic testing, and amazingly he was awake enough to drink it as we would periodically rouse him. His sugars got up high enough for us to transport him to the children's hospital for admission and further testing.... The office Doc first thought it could be diabetes. I immediately began to break down, as I knew what this meant. A lifetime of glucose testing, diet restrictions, hospitalizations... This could not be happening! But none of this would be clarified until days later... We got to Continue reading >>
