What are the different types of sickle cell disease?

Sickle cell disease or sickle cell disorder is a term often used to talk about a group of diseases affecting hemoglobin. It is the oxygen-carrying element of blood that makes up 2 alpha globins and 2 beta globins. Sickle cell disease happens due to beta-globin mutation and depending on the abnormality in mutation.

Types-
Sickle cell diseases can be of many types depending on the gene mutation in the blood. Some of the common types are-

Sickle hemoglobin s disease (ss)
Hemoglobin ss disease or sickle cell anemia is the most popular type of scd. It takes place when hemoglobin s gene mutation is inherited from both mother and father. In simple words, it happens when the child inherits one substitution beta-globin gene from each parent. In this type, the body only produces hemoglobin s. It is mostly found in people of african and indian origin.

Sickle hemoglobin- c disease (sc):
Patients with sickle hemoglobin sc disease have a moderately dissimilar swapping in their genes of beta-globin. Here, both hemoglobin c and hemoglobin s are inherited from each parent. It may cause similar symptoms like anemia but remains relatively l. People of west african and mediterranean origin are more prone to this.

Hbs beta-thalassemia
People with this type of scd inherit one sickle cell gene s and one gene for beta-thalassemia from each parent. Zero and plus are the two common types of beta-thalassemia. While beta 0 thalassemia usually takes a severe form, beta + thalassemia is a milder form of the disease.

Sickle beta-zero thalassemia
Beta-zero thalassemia takes form when the child inherits the beta s gene from one parent and beta 0 thalassemia gene mutation from the other. With similar symptoms to anemia, it is a slightly severe form of beta-thalassemia.

Sickle beta-plus thalassemia
Substitutions in both beta-globin genes take place in patients with sickle beta thalassemia (sb) disease. This may even lead to the requirement of blood transfusion if no normal beta globin is produced. Mediterranean and caribbean people are more likely to have this disorder.

Hemoglobin sd, hemoglobin se, and hemoglobin so
These are the few rare and not less common types of sickle cell diseases. They are also less severe. People with these forms of scd inherit one sickle cell gene s and one gene from uncommon hemoglobin (d, e, or o) from each parent.

Sickle cell trait
Hbas
People with sct have one sickle cell gene s and one normal gene a from both mother and father. Ones with this disorder show few to no signs of the disease and usually spend a normal life. However, the risk to their future generations still exists.
 

What Are The Different Types Of Sickle Cell Disease?

When abnormal cells grow inside the brain and are in the form of a mass the condition is called a brain tumour. However, on the other hand, brain cancer is a disease of the brain in which cancer cells (malignant cells) arise in the brain tissue. Cancer cells grow to form a mass of cancer tissue (tumour) that interferes with brain functions such as muscle control, sensation, memory, and other normal body functions. 

 ;

Some brain tumours are cancerous while others fall under the category of non-cancerous ones.

Brain cancer is actually the abnormal growth and uncontrolled growth of the cancer cells in the brain, that forms a tumour in the brain. Tumours can be either benign or malignant.

Benign brain tumours are abnormal collections of cells that reproduce slowly and usually remain separate from the surrounding normal brain.

Malignant tumours reproduce and grow quickly. Their borders are hard to distinguish from the normal brain around them.

 

The underlying cause of primary brain cancer, cancer that begins in the brain, is not known. Secondary brain cancer is caused by a cancer of another organ in the body, such as the breast, prostate, kidney, skin, or bone, that has spread to the brain.

 ;

The brain tumours originate in the brain itself. Tumours start to develop if there are mutations in the dna. It is because of these mutations that cells of the brain increasingly grow and divide. Usually, in adults, the primary brain tumours are uncommon in comparison to the secondary brain tumours.


 

There are few early symptoms of brain cancer, but as the tumour grows within the confines of the skull, it causes increased intracranial pressure and exerts pressure on the brain, causing signs to develop.


 ;

Brain cancer occurs when there is an uncontrolled growth of cancer cells in the brain that form a malignant brain tumour. The underlying cause of primary brain cancer, cancer that begins in the brain, is not known. Secondary brain cancer is caused by a cancer of another organ in the body, such as the breast, prostate, kidney, skin, or bone, that has spread to the brain.


 

What Is The Significant Difference Between Brain Tumour And Brain Cancer?

The most common forms of diabetes ;are type 1 and type 2 diabetes. In type 1, your immune system damages the cells inside the pancreas that produce insulin. Therefore, the pancreas are unable to produce an adequate amount of insulin.

In type 2 diabetes, your body does not respond properly to the insulin produced by the pancreas. As a result, your body will have a difficult time removing sugar ;from the blood. The cells may stop insulin production over time that may lead to insulin deficiency. However, there are other forms of diabetes that are lesser-known but can affect you just as bad.

Types of diabetes beyond type 1 and type 2

Gestational diabetes

In gestation diabetes, a condition that affects pregnant women, the blood sugar levels increase to an extent that may hamper the health of the mother and the child.

Symptoms

Usually, there are no symptoms as such. If diabetes worsens, women may observe symptoms such as -


	
	A need to pee more frequently
	
	
	Excessive thirst and hunger
	
	
	Dryness in the mouth
	


Lada (latent autoimmune diabetes in adults)

It is sometimes referred to as type 1.5 diabetes. Here, your immune system kills the insulin-producing cells inside the pancreas. As this condition takes a longer period to develop, you may not need insulin for many months after you have been diagnosed.

Symptoms

You may observe the following symptoms  


	
	Dryness and itchiness
	
	
	Tingling sensation in feet or hands
	
	
	Blurry vision
	
	
	Frequent urination
	


Mody (maturity-onset diabetes of the young)

This condition is observed during adolescence. Here, genetic mutations limit the pancreas from making insulin. So, due to insufficient insulin, your blood sugar level goes up. If any of your parents have mody, you are likely to have the condition.

Symptoms

Symptoms may include  


	
	Yeast and ;skin infections
	
	
	Frequent urination
	
	
	An urge to pee more often
	


Treatment

Primary care for these other forms of diabetes follows the usual course of treatment as with type 1 and type 2.


	
	Diabetic medications
	
	
	Insulin shots or injections
	
	
	Dietary changes
	


The doctor may instruct you to monitor your blood sugar levels frequently to keep it under control. This will be accompanied by a diet ;consisting of adequate calories, but avoid fatty foods, excess sugar and carbohydrates. Mild exercise is also recommended.

The best way to prevent these conditions is to visit your doctor frequently and follow the treatment plan. Do not keep your diabetes untreated.

A Sneak Peek Beyond Type 1 And Type 2 Diabetes

Abstract

Background: it is essential to have an understanding of life expectancy and risk factors among patients with sickle cell disease (sickle cell anemia, hemoglobin diseases, and thalassemias). These are required to counsel the patients, target treatment, and plan the right clinical trials.

 

Methods: a research followed 3764 people ranging from birth to 66 years of age and suffering from scd. The procedure was done to understand the life expectancy and calculate the average age at death. Moreover, the study understood the reasons for the death in all 209 adults. It used the proportional-hazards regression analysis to know the risks for an untimely death in adults with sickle cell anemia.

 ;

Results: when the results for young kids and adults with sickle cell anemia were observed, it was found that the average age at death was 48 for women and 42 for men. Moreover, suffering from hemoglobin c disease had an average mortality age of 60 for men and 68 years for women.

 

In people with sickle cell disease, 18% of deaths took place in patients with mainly renal organ failures. 33% of the tested patients were medically free of organ failures but episodes of pain crisis took their life. Out of these patients, 78% experienced chronic pain, chest syndrome, or both, while 22% suffered a stroke that took their lives.

 ;

Clinical modeling showed that people with sickle cell anemia faced acute chest syndrome, seizures, kidney failure, a white-cell count of over 15, 000 per cubic mm, and a low hemoglobin level were related to a risk of early death.

 

Conclusions: results suggested that 50% of patients with sickle cell anemia lived beyond the age of 50. A huge share of those who lost their lives suffered no noticeable chronic organ failure. However, most of them died due to acute episodes of pain or stroke. Early death was seen highest among patients who had symptomatic disease. High levels of fetal hemoglobin suggested improved chances of survival and are assumably a credible source to foresee the risks and other factors related to adult life expectancy.

Life Expectancy And Risk Factors Involved In Sickle Cell Disease

Atherosclerosis refers to a medical condition in which the arteries become hardened and narrowed due to the accumulation of cholesterol plaque in the walls of the artery, obstructing the flow of blood.

What are the causes?

Atherosclerosis is a slow but progressive disorder that starts with the damage of endothelium   cells lining the interior surface of lymphatic and blood vessels. This allows bad ldl cholesterol to build up in the artery walls. Over time, a plaque made of calcium, macrophages, and cholesterol grows to a certain size to clog up arteries, disrupting blood flow around the body.

Other factors leading to atherosclerosis to include  

High blood pressure

High levels of triglyceride in the blood

High cholesterol levels

Certain medical conditions   diabetes, obesity, insulin resistance

Smoking/use of tobacco

Inflammatory conditions like lupus and arthritis

Symptoms of atherosclerosis

Atherosclerosis may develop in childhood or during adolescence. Mild conditions may not reveal observable symptoms unless the arteries are clogged, and blood supply to the tissues and organs are restricted.

Signs of moderate to severe atherosclerosis depend on the affected arteries   it could be the arteries leading to your brain, your heart, legs and arms, or the kidney. The symptoms of atherosclerosis include  

Weakness and fatigue

Difficulty breathing/concentrating

Headaches

Facial numbness

Paralysis

Vomiting

Chest pain

Anxiety

Loss of appetite

Swelling in the feet and hands

If any of the above symptoms seem familiar to you, consult a doctor right away for treatment.

Can atherosclerosis be prevented?

The best way to avoid cholesterol plaque from building up in the artery walls is to prevent the onset of atherosclerosis with these preventive measures.

Eat healthy   avoid eating foods that are rich in saturated fats   red meat, butter and cheese. These increase your cholesterol levels drastically. Instead, include foods that contain unsaturated fats, like avocados, olive oil, fatty fish, nuts and seeds because these help to keep ldl or bad cholesterol levels down.

Stay active   exercising and staying active can help regulate your cholesterol levels and prevent certain conditions that might put you at risk for atherosclerosis.

Quit smoking   people who smoke should quit smoking because it is a major risk factor for atherosclerosis   it increases blood pressure, which in turn, affects your cholesterol levels.

Atherosclerosis can lead to complications. With precautionary measures and proper treatment, the condition can be avoided.

C-reactive protein ;is a type of protein produced by the liver in response to an infection ;or inflammation. When your body contracts an infection, the white blood cells produce proteins to fight it. Some of these proteins activate the liver into producing c-reactive protein. For many years, the crp ;blood level has been used to ascertain the level of infection or inflammation.

Assessing the risk of heart disease ;with c-reactive protein

The level of crp is a potential indicator of how likely you are to develop cardiovascular diseases. This is because the development of atherosclerosis is linked with inflammation within the walls of your blood vessel. This results in higher levels of c-reactive protein in atherosclerosis patients than in those without the disorder.

The greater the crp levels, the more chances you have of being affected by cardiovascular disorders. The test also determines the risk of a second attack.

The value of knowing your crp levels depends on whether you come under one of three cardiovascular risk groups.


	
	High risk   not important to know crp because you should be combining lifestyle changes and aggressive treatment to reduce risk
	
	
	Intermediate risk   helpful to find out crp levels, as it can provide vital information crucial in deciding the next line of treatment
	
	
	Low risk   even if your crp levels are high, you will not be at risk   due to negligible risk factors and low cholesterol levels   that should require more than just lifestyle changes
	


To find out crp levels you will have to take a blood test. C-reactive protein is classified into  


	
	High   equal to or greater than 3
	
	
	Intermediate   between 1 and 3
	
	
	Low   below 1
	


If you are having a c-reactive protein test to check for heart diseases, your healthcare provider may recommend a cholesterol test as well. A number of other tests may also be prescribed to evaluate your risk further.
