Children
• Biologically, A child is generally a human between the stages of birth and puberty
• United Nations Convention on the Rights of the Child defines child as “a human being below the age of 18 years unless under the law applicable to the child, majority is attained earlier”
![Page 4: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/4.jpg)
Adolescence
• A transitional stage of physical and psychological human development that generally occurs during the period from puberty to legal adulthood.
![Page 5: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/5.jpg)
Why Special?• Changes in insulin sensitivity related to sexual
maturity and physical growth
• Ability to provide self care
• Supervision in child care and school
• Unique neurological vulnerability to hypoglycemia, hyperglycemia of DKA
![Page 6: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/6.jpg)
Type 2 Diabetes Mellitus
![Page 7: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/7.jpg)
• It is assumed that prevalence of T2DM under 20 years of age will quadruple in 40 years.
![Page 8: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/8.jpg)
Testing Protocol in T2DM (< 18yrs)
• Asymptomatic Children:
–Overweight:–BMI > 85th percentile for age and sex–Weight for height > 85th percentile–Weight > 120% of ideal for height
![Page 9: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/9.jpg)
• Any two of the following risk factors:
– Family history of T2DM– Race/Ethnicity– Signs of Insulin resistance or associated conditions– Maternal history of Diabetes or GDM
![Page 10: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/10.jpg)
• Age of initiation:• At 10 years of age, or• At puberty, if puberty is earlier
• Checking should be done every 3 years
![Page 11: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/11.jpg)
Suitable Tests
• Validity of HbA1c in the pediatric population under question
• OGTT and FPG more suitable
• For now, aside from rare instances like cystic fibrosis and hemoglobinopathies, HbA1c is recommended
![Page 12: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/12.jpg)
Do not miss!!
• Blood Pressure measurement
• Fasting lipid panel
• Assessment of Albumin excretion
• Dilated eye examination
![Page 13: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/13.jpg)
Type 1 Diabetes Mellitus
![Page 14: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/14.jpg)
• 5-10% of all cases of Diabetes Mellitus
• 75% of all cases diagnosed as T1DM < 18 years of age
![Page 15: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/15.jpg)
• Can be immune mediated or idiopathic
• Immune mediated variety was previously called “juvenile onset diabetes”
• The rate of ß-cell destruction is variable, being rapid in infants and children
• Children & adolescents may present with DKA more
![Page 16: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/16.jpg)
Diagnosis
• According to ADA Criteria for Diagnosis of Diabetes
• Autoimmune Markers:• Islet cell autoantibodies• Autoantibodies to Insulin• Autoantibodies to GAD• Autoantibodies to ZnT8
![Page 17: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/17.jpg)
• Early diagnosis may limit acute complications
• Extend long term endogenous insulin production if diagnosed early
![Page 18: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/18.jpg)
Associated Autoimmune Conditions
–Thyroid disease:• TSH:– If normal, repeat every 1-2 years
• Anti-TPO and anti-TG Ab
–Autoimmune Gastritis:• S. B12 assay
![Page 19: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/19.jpg)
• Celiac Disease:
• Anti tTG IgG• Anti Deamidated Gliadin IgG
![Page 20: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/20.jpg)
Glycemic Goals
• HbA1c: <7.5%
• Before meals: 5.0-7.2 mmol/L
• Bedtime: 5.0-8.3 mmol/L
![Page 21: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/21.jpg)
• Should be individualized
• Should consider long term benefits of A1c Control and risks of hypoglycemia
![Page 22: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/22.jpg)
Remember!
• Attain low BG as safely as possible
• Stepwise goals
• Hypoglycemic unawareness (<6yrs)
• Near normalization of glucose levels more difficult to achieve in adolescents than in adults
![Page 23: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/23.jpg)
To Avoid Hypoglycemia
• Insulin analogues
• Continuous Glucose Monitoring
• Low glucose suspend insulin pumps
• Education
![Page 24: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/24.jpg)
Management of Blood Pressure
• High normal BP: (>90th percentile)• Dietary intervention• Exercise• Drugs (if no improvement for 3-6 months)
• Hypertension: (> 95th percentile)• ACE inhibitors• ARBs
• Goal:• Consistent BP < 90th percentile for age, sex and
height
![Page 25: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/25.jpg)
Management of Dyslipidemia
• Obtain a Fasting Lipid Profile at or above 2 years of age:• If abnormal, monitor annually• If LDL <100 mg/dl, repeat every 5 years
![Page 26: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/26.jpg)
• Initial Therapy:• Optimized glucose control•MNT (Medical Nutrition Therapy)
• After the age of 10 years:• LDL >160 mg/dl, or• LDL > 130 mg/dl and one or more CVD
risks
• Goal: • LDL <100 mg/dl
![Page 27: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/27.jpg)
Smoking
• Discourage all sorts of smoking, including e-cigarettes

Screening for Microvascular complications
• Nephropathy:• At least annually: (if diabetic for > 5
years)–Spot urine for ACR
• Creatinine clearance/ eGFR: – Initially once, then based on age, duration,
treatment etc.
![Page 29: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/29.jpg)

Monogenic Diabetes Syndromes• Diagnosed within first 6 months of life or
within 25 years• Strong family history but not typical of T2DM• Mild fasting hyperglycemia:
• 100-150 mg/dl (5.5-8.5 mmol/L)
• Diabetes with:• Negative Autoantibodies• No signs of Insulin resistance• No Obesity
![Page 33: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/33.jpg)

• Permanent form can be well managed with Sulfonylureas
![Page 34: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/34.jpg)
Maturity-Onset Diabetes of the Young(MODY)
• Age below 25 years
• Inherited as Autosomal Dominant pattern
• Impaired insulin secretion
• Minimal or no defects in insulin action
![Page 35: Care of Diabetes in Children and Adolescents](https://reader033.fdocuments.us/reader033/viewer/2022042907/5884c0a41a28ab34778b6c71/html5/thumbnails/35.jpg)
Importance MDS
• To avoid suboptimal treatment regimens
• Unnecessary delay in diagnosing other family members
