In many cases, neonatal diabetes may be treated with oral sulfonylureas such as glyburide. Physicians may order genetic tests to determine whether or not transitioning from insulin to sulfonylurea drugs is appropriate for a patient.

The transfer from insulin injections to oral glibenclamide therapy seems highly effective for most patients and safe. This illuminates how the molecular understanding of some monogenic form of diabetes may lead to an unexpected change of the treatment in children. This is a spectacular example of how the pharmacogenomic approach improves in a tremendous way the quality of life of the young diabetic patients.

Insulin Therapy

- Long Acting Insulin: (Insulin glargine)-is a hormone that works by lowering levels of blood glucose. It starts to work several hours after an injection and keeps working for 24 hours. It is used to manage blood glucose of diabetics. It is used to treat Type 1 and 2 diabetes in adults and Type 1 diabetes in kids as young as 6 years old.

- Short Acting Insulin (e.g. Novolin or Velosulin)-It works similarly to natural insulin and takes up to 30 minutes and lasts for about 8 hours depending on the dosage used.

- Intermediate Insulin: (e.g. NPH insulin)- Usually taken in combination with a short acting insulin. Intermediate acting insulin starts to activate within the first hour of injecting and enters a period of peak activity lasting for 7 hours.

Sulfonylureas

- Sulfonylureas: This medication signals the pancreas to release insulin and help the body's cells use insulin better. This medicaiton can lower A1C levels ( AIC is defined as a measurement of the blood glucose after previous 2–3 months) by 1-2%.

Chronic hyperglycemia due to any cause can eventually cause blood vessel damage and the microvascular complications of diabetes. The principal treatment goals for people with MODY — keeping the blood sugars as close to normal as possible ("good glycemic control"), while minimizing other vascular risk factors — are the same for all known forms of diabetes.

The tools for management are similar for all forms of diabetes: blood testing, changes in diet, physical exercise, oral hypoglycemic agents, and insulin injections. In many cases these goals can be achieved more easily with MODY than with ordinary types 1 and 2 diabetes. Some people with MODY may require insulin injections to achieve the same glycemic control that another person may attain with careful eating or an oral medication.

When oral hypoglycemic agents are used in MODY, the sulfonylureas remain the oral medication of first resort. When compared to patients with type 2 diabetes, MODY patients are often more sensitive to sulphonylureas, such that a lower dose should be used to initiate treatment to avoid hypoglycaemia. Patients with MODY less often suffer from obesity and insulin resistance than those with ordinary type 2 diabetes (for whom insulin sensitizers like metformin or the thiazolidinediones are often preferred over the sulfonylureas).

Clinical Trials of NDM

- The research article is entitled, "A Successful Transition to sulfonamides treatment in male infant with novel neonatal diabetes mellitus (NDM) caused by the ABBC8 gene mutation and 3 years follow up". It is a case study on the transitioning of treatments from insulin therapy to sulfonamides therapy. NDM is not initiated by an autoimmune mechanism but mutations in K-sensitve channel, "KCNJ11, ABCC8" and "INS" genes are successful targets for changing treatments from insulin to sulfonamides therapy.

- Introduction: Within this study a two month old male was admitted into the intensive care unit, because the he was showing signs of diabetic ketoacidosis. Other symptoms include, respiratory tract infection, sporous, dehydration, reduced subcutaneous fat, Candida mucous infection. The infant's family history was negative for diseases of importance to hereditary and the eldest sibling was healthy.

- Experiment: The current treatment plan consist of therapy for ketoacidosis was started upon admissions into the hospital. Also, subcutaneous insulin was given (0.025-0.05 units/kg/h) and adjusted to the glycaemic profiles and the patient was converted to euglycaemic state. After 24 hours, oral intake of insulin started and treatment continued with subcutaneous short acting insulin then intermediate acting insulin plus 2 dosage of short acting insulin. A genetic analysis was conducted for NDM and mutation of KCNJ11, "ABCC8" and "INS" genes have been given. Sequence analysis showed a rare heterogeneous missense mutation, PF577L, in the patient's exon 12 of ABCC8 gene. This confirms diagnosis of NDM caused by heterozygous mutation in the SUR1 subunit of the pancreatic ATP-sensitive potassium channel, because his parents' white blood cells did not show signs of this mutation.

- Results: Switching from the insulin therapy to the sulfonamides was a successful treatment. It is the current regimen used to treat NDM.

- Discussion/Conclusion: ABCC8 gene produces SUR1 protein subunit that interacts with pancreatic ATP-sensitive potassium channel. When the channel opens a large amount of insulin is released. Mutations that occur in ABCC8 are associated with congential hyperinsulinism and PNDM or TNDM. Patients that have mutations in their potassium channel, improved their glucose levels with sulfonylurea regimen and glibenclamide showed successful results in managing glucose levels as well.

- A 2006 study showed that 90% of patients with a KCNJ11 mutation were able to successfully transition to sulfonylurea therapy.

In some forms of MODY, standard treatment is appropriate, though exceptions occur:

- In MODY2, oral agents are relatively ineffective and insulin is unnecessary.

- In MODY1 and MODY3, insulin may be more effective than drugs to increase insulin sensitivity.

- Sulfonylureas are effective in the K channel forms of neonatal-onset diabetes. The mouse model of MODY diabetes suggested that the reduced clearance of sulfonylureas stands behind their therapeutic success in human MODY patients, but Urbanova et al. found that human MODY patients respond differently to the mouse model and that there was no consistent decrease in the clearance of sulfonylureas in randomly selected HNF1A-MODY and HNF4A-MODY patients.

The most common method to manage hypoglycemia and diabetes is with an insulin pump. . However in infants and very young children long acting insulins like Glargine and Levemir are preferred to prevent recurrent hypoglycemia . As soon as parent knows Walcott-Rallison syndrome is the source, treatment or therapy plans need to be drawn up along with frequent check ins to make sure kidney and liver functions are around normal and insulin therapy are working. If needed, the patient can undergo thyroxin therapy in order to maintain proper thyroid stimulating hormone levels. This has only been needed in a few cases were hypothyroidism was present in the patient.

In adults, fibrates and statins have been prescribed to treat hyperglycerolemia by lowering blood glycerol levels. Fibrates are a class of drugs that are known as amphipathic carboxylic acids that are often used in combination with Statins. Fibrates work by lowering blood triglyceride concentrations. When combined with statins, the combination will lower LDL cholesterol, lower blood triglycerides and increase HDL cholesterol levels.

If hyperglycerolemia is found in a young child without any family history of this condition, then it may be difficult to know whether the young child has the symptomatic or benign form of the disorder. Common treatments include: a low-fat diet, IV glucose if necessary, monitor for insulin resistance and diabetes, evaluate for Duchenne muscular dystrophy, adrenal insufficiency & developmental delay.

The Genetic and Rare Diseases Information Center (GARD) does not list any treatments at this time.

It has been suggested that a possible method of treatment for histidinemia is through the adoption of a diet that is low in histidine intake. However, the requirement for such dietary restrictions is typically unnecessary for 99% of all cases of histidinemia.

No treatment is available to cure or slow down the progression of aspartylglucosaminuria. Bone marrow transplants have been conducted in hope that the bone marrow will produce the missing enzyme. The results of the tests thus far have shown to be inconclusive.

Since ear infections and respiratory infections are common for children diagnosed with aspartylglucosaminuria, it is best to have regular checkups for both the ears and the respiratory tract.

Extreme sensitivity to the sun’s rays may develop; the best way to protect an individual diagnosed with aspartylglucosaminuria is to have them wear sunglasses, hats or caps to protect their eyes.

Epilepsy and insomnia can both be treated with medication.

It will be beneficial to children who are diagnosed with AGU to receive an education from a school with special teaching.

There is no cure available for Weaver syndrome. However, with multidisciplinary management such as neurological, pediatric, orthopedic, and psychomotor care and genetic counseling, symptoms can be managed. Surgery may be used to correct any skeletal issues. Physical and occupational therapy are considered an option to help with muscle tone. Also, speech therapy is often recommended for speech related problems.

There is no proven treatment for congenital lactic acidosis. Treatments that are occasionally used or that are under investigation include the ketogenic diet and dichloroacetate. Other treatments aim to relieve symptoms – for example, anticonvulsants may be used to relieve seizures.

Nucleoside bypass therapy is an experimental treatment aimed to restore the normal levels of deoxyribonucleotides (dNTPs) in mitochondria.

Patients with PDE do not respond to anticonvulsant medications, but seizures rapidly cease with therapeutic intravenous doses of Vitamin B6 and remission from seizures are often maintained on daily therapeutic doses of Vitamin B6. An optimal dose has not yet been established, but doses of 50–100 mg/day or 15–30 mg/kg/day have been proposed. Importantly, excessive doses of vitamin B6 can result in irreversible neurological damage, and therefore several guidelines recommend 500 mg per day as the maximal daily dose.

Despite remission of seizure activity with vitamin B6 supplementation, intellectual disability is frequently seen in patients with PDE. Because the affected enzyme antiquitin is involved in the cerebral lysine degradation pathway, lysine restriction as an additional treatment modality has recently been explored. Studies have been published which demonstrate potential for improved biomarkers, development, and behavior in patients treated with lysine restriction in addition to pyridoxine supplementation. In trial, lysine restriction of 70–100 mg/kg/day in children less than 1 year of age, 45–80 mg/kg/day in children between 1–7 years of age, and 20–45 mg/kg/day in children older than 7 years of age were prescribed. Despite the potential of additional benefit from lysine restriction, vitamin B6 supplementation remains the main-stay of treatment given lack of studies thus far demonstrating the safety and efficacy of lysine restriction for this purpose.

The only treatment for MWS is only symptomatic, with multidisciplinary management

CTD is difficult to treat because the actual transporter responsible for transporting creatine to the brain and muscles is defective. Studies in which oral creatine monohydrate supplements were given to patients with CTD found that patients did not respond to treatment. However, similar studies conducted in which patients that had GAMT or AGAT deficiency were given oral creatine monohydrate supplements found that patient’s clinical symptoms improved. Patients with CTD are unresponsive to oral creatine monohydrate supplements because regardless of the amount of creatine they ingest, the creatine transporter is still defective, and therefore creatine is incapable of being transported across the BBB. Given the major role that the BBB has in the transport of creatine to the brain and unresponsiveness of oral creatine monohydrate supplements in CTD patients, future research will focus on working with the BBB to deliver creatine supplements. However, given the limited number of patients that have been identified with CTD, future treatment strategies must be more effective and efficient when recognizing individuals with CTD.

There are no treatments for MDDS, but some of the symptoms can be managed. For survivors living with MDDS, there are drugs to control epilepsy, and physical therapy can help with muscle control. Liver transplants may benefit people with liver involvement.

There is no cure for ONH; however, many therapeutic interventions exist for the care of its symptoms. These may include hormone replacement therapy for hypopituitarism, occupational, physical, and/or speech therapy for other issues, and services of a teacher of students with blindness/visually impairment. Special attention should be paid to early development of oral motor skills and acclimation to textured foods for children with texture aversion, or who are otherwise resistant to eating.

Sleep dysfunction can be ameliorated using melatonin in the evening in order to adjust a child's circadian clock.

Treatment for strabismus may include patching of the better eye, which may result in improved vision in the worse eye; however, this should be reserved for cases in which the potential for vision improvement in both eyes is felt to be good. Surgery to align the eyes can be performed once children with strabismus develop equal visual acuity in both eyes, most often after the age of three. Generally surgery results in improved appearance only and not in improved visual function.

Most patients suffering from KTS have epilepsy that is resistant to anti-epileptic agents. Some patients showed a partial response to treatment, but very few were able to stop their epilepsy through treatment. One case was responsive to treatment using Phenobartbital and vigabatrin which are both anti-epileptic agents. Spasticity can be treated with baclofen, but not all patients are responsive to the treatment.

Treatment for CLSD is largely focused on treating the symptoms of the disorder, because it is still in the early stages of research. Symptomatic treatment is also the only option due to the genetic nature of the disorder. Treatment may include surgeries to correct facial and cranial dysmorphisms or therapy sessions to help alleviate behavioral abnormalities associated with the disorder.

With appropriate treatment and management, patients with Weaver syndrome appear to do well, both physically and intellectually, throughout their life and have a normal lifespan. Their adult height is normal as well.

Treatment plans will vary depending on the severity of the condition and its evidences in each patient.

Areas that will probably need to be evaluated and assessed include speech, vision, hearing and EEG. Treatment measures may include physical therapy, occupational therapy, Speech therapy, anti-seizure drugs and orthotic devices. Surgery may be needed to assuage spastic motor problems. Various supportive measures such as joint contractures that could prevent complications.

Genetic counseling may also be recommended

Like many mitochondrial diseases, there is no cure for MERRF, no matter the means for diagnosis of the disease. The treatment is primarily symptomatic. High doses of Coenzyme Q10, B complex vitamins and L-Carnitine are the drugs that patients are treated with in order to account for the altered metabolic processed resulting in the disease. There is very little success with these treatments as therapies in hopes of improving mitochondrial function. The treatment only alleviates symptoms and these do not prevent the disease from progressing. Patients with concomitant disease, such as diabetes, deafness or cardiac disease, are treated in combination to manage symptoms.

Treatment is symptomatic, often addressing indicators associated with peripheral pulmonary artery stenosis. Laryngotracheal calcification resulting in dyspnea and forceful breathing can be treated with bronchodilators including the short and long-acting β2-agonists, and various anticholinergics. Prognosis is good, yet life expectancy depends on the severity and extent of diffuse pulmonary and arterial calcification.

Plasma and cerebrospinal fluid levels of pipecolic acid are frequently elevated in patients with PDE, though it is a non-specific biomarker. α-aminodipic semialdehyde is elevated in urine and plasma and is a more specific biomarker for PDE. Improvements in these biomarkers have been reported with the implementation of a lysine-restricted diet. Initial studies evaluating the safety and efficacy of lysine restriction evaluated developmental and cognitive outcomes by age-appropriate tests and parental observations.

At the hospital, physicians follow standard protocol for managing seizures. Cluster seizures are generally controlled by benzodiazepines such as diazepam, midazolam, lorazepam or clonazepam. The use of oxygen is recommended in the United States, but in Europe it is only recommended in cases of prolonged epileptic status.
