How many types of OI are there?
There are at least 19 recognized forms of osteogenesis imperfecta, designated type I through type XIX. Several types are distinguished by their signs and symptoms, although their characteristic features overlap. Increasingly, genetic causes are used to define rarer forms of osteogenesis imperfecta.
What is the most common OI?
Some of the most common OIs in people with HIV are: Herpes simplex virus 1 (HSV-1) infection—a viral infection that can cause sores on the lips and mouth. Salmonella infection—a bacterial infection that affects the intestines.

OI type II is the most severe type of osteogenesis imperfecta. Affected infants often experience life-threatening complications at birth or shortly after. Infants with OI type II have low birth weight, abnormally short arms and legs and blue sclera.
What is the classification of OI?

What is OI type 3 severe?
Type III. Most severe type in babies who don’t die as newborns. At birth, a baby may have slightly shorter arms and legs than normal and arm, leg, and rib fractures. A baby may also have a larger than normal head, a triangle-shaped face, a deformed chest and spine, and breathing and swallowing problems.
What are 5 opportunistic infection?
HIV-related OIs include pneumonia, Salmonella infection, candidiasis, toxoplasmosis, and tuberculosis (TB).
Do people with OI have teeth?
About half of the people who have OI have teeth that appear normal, and their major concerns are routine care. However, the other half has a defect in the teeth called Dentinogenesis Imperfecta (DI), sometimes referred to as opalescent teeth or brittle teeth.
What causes osteogenesis imperfecta Type 3?
OI type III is caused by changes in the COL1A1 or COL1A2 genes and is inherited in an autosomal dominant manner.
Is OI dominant or recessive?
Most types of OI are inherited in an autosomal dominant pattern. Almost all infants with the severe type II OI are born into families without a family history of the condition. Usually, the cause in these families is a new mutation in the egg or sperm or very early embryo in the COL1A1 or COL1A2 gene.
How long does someone with osteogenesis imperfecta live?
The median survival time in the OI cohort was 72.4 years for males (compared to 81.5 years in the reference population) and 77.4 for females (compared to 84.5 in the reference population).
Does osteogenesis imperfecta get worse with age?
It causes bones to break easily. In type 3 OI, your child’s body produces enough collagen but it’s poor quality. Your child’s bones can even begin to break before birth. Bone deformities are common and may get worse as your child gets older.
Is osteogenesis imperfecta a disability?
Typically, applying for and receiving social security disability benefits can take many months. But what if your disabling condition is so severe that you cannot wait? OI type II is a disabling condition on the Compassionate Allowance List, which qualifies an individual for an expedited approval process.
How is OI diagnosed?
There is no specific test for OI. Your doctor uses your medical and family history, physical exam, and imaging and lab tests to diagnose it. Your doctor may also test your collagen (from skin) or genes (from blood). There is no cure, but you can manage symptoms.
What is the life expectancy of OI?
Life expectancy for males with OI was 9.5 years shorter than that for the general population (72.4 years vs 81.9 years), and for females, was 7.1 years shorter than that for the general population (77.4 years vs 84.5 years).
What is the treatment for brittle bone disease?
taking regular exercise to keep your bones as strong as possible. healthy eating – including foods rich in calcium and vitamin D. taking a daily supplement containing 10 micrograms of vitamin D. making lifestyle changes – such as giving up smoking and reducing your alcohol consumption.
Who discovered OI?
The earliest known case of OI is in a partially mummified infant’s skeleton from ancient Egypt now housed in the British Museum in London. In 1835, Lobstein coined the term osteogenesis imperfecta and was one of the first to correctly understand the etiology of the condition.
Is osteogenesis imperfecta painful?
Conclusions: Pain is a common occurrence for children with OI and is both acute and chronic in nature, interfering with children’s daily living activities. OI pain may not be optimally treated because many children experienced moderate to severe pain despite use of analgesics and/or coping strategies.
Can OI be cured?
To date, there is no known treatment, medicine, or surgery that will cure osteogenesis imperfecta (OI). The goal of treatment is to prevent deformities and fractures and allow the child to function as independently as possible. Treatments for preventing or correcting symptoms may include: Care of fractures.
