Introduction

Pediatric diabetes can be a scary and life-changing diagnosis. However, with proper management, patients with pediatric diabetes can live long, full lives. Patients with pediatric diabetes—and their parents and caregivers—will take their cues from health care professionals when it comes to managing diabetes. Having an in-depth knowledge of the pathophysiology and management techniques of diabetes will allow health clinicians to provide reassuring knowledge and treatment options to their patients. Knowledge and information are powerful tools for every member of the healthcare management team to provide optimal care and a high quality of life for the patient.

Type 1 diabetes mellitus, previously known as juvenile diabetes, is a chronic and progressive metabolic disorder wherein the body is unable to produce insulin to meet its energy needs. The condition is a result of autoimmune destruction of the beta cells in the pancreas. As its former name suggests, the disease has an early onset, usually before 18 years of age. Once diagnosed, an individual will require lifelong insulin treatment and monitoring for complications.

Type 1 diabetes mellitus is also known as insulin-dependent diabetes mellitus (IDDM) because the pancreas is completely unable to produce insulin, as opposed to type 2 diabetes mellitus, which is where the pancreas produces insufficient amounts of insulin to sustain the energy requirements of the body.

According to the CDC, type 1 diabetes is caused by mechanisms much different from those that cause type 2 diabetes mellitus. Despite prolific research into the origins of the disease, the exact etiology of both types of diabetes remains unclear. Nevertheless, studies in the recent years have primarily pointed out its onset as following exposure to environmental stimuli such as a virus and certain dietary factors in genetically predisposed individuals. However, because of the very early onset of the disease in pediatric populations, the role of genetic factors is also a very important consideration.

The onset of pediatric type 1 diabetes mellitus can occur at any pre-pubertal age, however, the peak incidence usually increases with age until mid-puberty and then declines. This means that the majority of these patients are school-age children whose care and wellbeing is entrusted to the school and day care personnel for the majority of their day. In this case, it is the school nurses, teachers or other personnel trained to perform diabetes care, as part of the interdisciplinary pediatric diabetes healthcare (DHC) team, who are responsible for them especially when it comes to glycemic monitoring, insulin administration and carbohydrate counting of meals. They are also partly responsible for educating the patient about their disease, its management and treatment.

It is important for all health professionals, not just nurses, who are part of the interdisciplinary pediatric diabetes healthcare (DHC) team to be able to provide continuous counseling as patients grow older, and lean toward independent and self-management of the disease. The course is intended to enhance and reinforce the knowledge of health professionals on type 1 diabetes mellitus in pediatric patients, especially with regards to their diagnosis, management, treatment and overall long-term health education.

Pathophysiology

Type 1 diabetes mellitus is a result of the autoimmune destruction of the beta cells of the pancreas.

Hypotheses

Current studies have several hypotheses on the etiologic origins of the disease, pathologic mechanisms and presentation, and progression to microvascular comorbidities. The pathophysiologic mechanisms at play primarily involve both genetic and environmental factors, and are discussed in detail below.

Genetic Factors

The genetic component of this form of diabetes is complex and involves multiple genes but there is also high risk among siblings, especially monozygotic twins.1 A study by Tseck, et al. found dizygotic twins to possess a 5-6 percent concordance rate for type 1 diabetes mellitus2 while monozygotic twins are half more likely to have similar diagnosis upon reaching 40 years old.3

Children of parents with type 1 diabetes mellitus are also at greater risk for the same disease themselves. However, the risk differs depending on which of the parents has the disease. Those with mothers who have diabetes possess the relatively small risk of 2-3 percent to develop the disease themselves, as compared to those with fathers who have diabetes, which increases their risk of developing it to 5-6 percent. However, if both parents have diabetes, the risk for a child to also develop diabetes increases to about 30 percent. Additionally, the risk is relatively greater if the onset of the parent(s) disease happened prior to the age of 11 years old, and relatively lesser if the onset happened at a later age.

The genetic component of diabetes is also apparent in the important difference seen in its frequency of occurrence among various ethnic groups. Type 1 diabetes mellitus is very common in individuals with European ancestry, with those from northern Europe significantly more affected compared to those from the Mediterranean region.4 It is most uncommon among people of East Asian descent.5

Studies on genome-wide association found several loci linked with diabetes, although there were not enough causal relations found. The regions most commonly linked to other autoimmune diseases, the major histocompatibility complex (MHC), is also where various susceptibility loci for diabetes, specifically, class II human leukocyte antigen (HLA) DR and DQ haplotypes (the detected amino acids involved in the disease process), are found.6,7,8

A list of DR-DQ haplotypes linked to greater risk for diabetes type I is found below, in hierarchical order:6

·  DRB1*0301 - DQA1*0501 - DQB1*0201 (odds ratio [OR] 3.64)

·  DRB1*0405 - DQA1*0301 - DQB1*0302 (OR 11.37)

·  DRB1*0401 - DQA1*0301 - DQB*0302 (OR 8.39)

·  DRB1*0402 - DQA1*0301 - DQB1*0302 (OR 3.63)

·  DRB1*0404 - DQA1*0301 - DQB1*0302 (OR 1.59)

·  DRB1*0801 - DQB1*0401 - DQB1*0402 (OR 1.25)

Approximately 90-95 percent of young children diagnosed with the disease are carriers of the HLA-DR3 DQB1*0201, HLA-DR4 DQB1*0302, or both. Children who carry haplotypes DR3 and DR4 heterozygotes are the most susceptible. As mentioned previously, the individuals who carry the aforementioned haplotypes and therefore, at most risk, are primarily of European descent. There is not enough study data on other ethnic populations.

An important gene that plays a role in the pathophysiology of type 1 diabetes mellitus is the insulin gene (INS). It encodes for the pre-proinsulin peptide, which is close to a variable number of tandem repeats (VNTR) polymorphism at chromosome 11p15.5.9 Various VNTR alleles can promote both resistance and susceptibility to type 1 diabetes mellitus via their action on insulin gene (INS) transcription in the thymus gland.

Environmental factors

Environmental triggers may also contribute to the development of type 1 diabetes mellitus. These triggers include viruses such as enterovirus,12 mumps, rubella, and coxsackievirus B4, toxic drugs and chemicals, cytotoxins, and exposure to cow’s milk during infancy.13

It is important to remember that a combination of factors may be at play, instead of just one. A study by Lempainen, et al. found that evidence of an enterovirus infection as early as 1 year of age was tied to the appearance of type 1 diabetes mellitus–related autoimmunity among children exposed to cow's milk before the age of 3 years old. This finding strongly suggests a relationship between the two factors. In addition, the finding also offers a possible explanation for the conflicting findings obtained in studies that only studied these factors individually.14

The finding of one meta-analysis points to a weak but important linear elevation in the risk of pediatric type 1 diabetes mellitus associated with increasing maternal age.15 However, there is insufficient evidence to support any substantial increase in type 1 diabetes mellitus risk in children after preeclampsia complications during pregnancy.16

A study by Simpson, et al. based in Denver, Colorado, followed children at increased risk of diabetes since 1993 and did not find any link between vitamin D intake nor 25-hydroxyvitamin D levels during childhood to be linked with autoimmune destruction of the islets of Langerhans nor progression to type 1 diabetes mellitus.17 Another risk factor for the development of type 1 diabetes mellitus may be upper respiratory infection during the first year of life. A data analyzed 148 children who were carriers of genetic markers of the disease and found that upper respiratory infections in the first year of life were linked to greater risk for type 1 diabetes mellitus.18,19
