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?

Hepatitis is a condition that affects the liver by causing inflammation which is a common outcome resulting from a viral infection. While different types of hepatitis diseases are caused by different causes, there are some reasons like medications, toxins, alcohol, and drugs that are typically known.

 

Types

The five common types of viral hepatitis are hepatitis a, b, c, d, and e.

 ;


	
	Hepatitis a
	


Hepatitis a is the result of an infection caused by the hepatitis a virus. This type of hepatitis is an acute disease.

 


	
	Hepatitis b
	


The hepatitis b virus causes hepatitis b. This is often a chronic disease that lasts longer.

 ;


	
	Hepatitis c
	


Hepatitis c comes from the hepatitis c virus. It is one of the most common bloodborne infections in the world. It is a long-lasting condition.

 


	
	Hepatitis d
	


This is a not so commonly found form of hepatitis that only occurs in hepatitis b infected people. This virus not only causes liver inflammation but also cannot be contracted without an existing hbv infection.

 ;


	
	Hepatitis e
	


Hepatitis e is waterborne. Hepatitis e virus infection is responsible for it. It is generally acute but can be severely chronic for pregnant women.


 

Causes of viral hepatitis

It is true that different types of viral hepatitis infections are caused by distinct modes of transmission. Here are the causes of a hepatitis infection:

 ;


	
	Hepatitis a- when a person is exposed to the hepatitis a virus through food or water.
	


 


	
	Hepatitis b- when an individual comes in contact with hepatitis b virus through the transmission of bodily fluids like blood, semen, etc.
	


 ;


	
	Hepatitis c- when someone gets infected with the hepatitis c virus through the contamination of bodily fluids.
	


 


	
	Hepatitis d- when a person is exposed to hepatitis d virus-infected blood, it causes this disease.
	


 ;


	
	Hepatitis e- when a person comes in contact with the hepatitis e virus through water or food.
	


 

Causes of non-viral hepatitis

Although hepatitis is commonly caused due to an infection, other factors can also be reasons to cause hepatitis.

 ;

Alcohol

Excessive alcohol can lead to liver damage, causing inflammation. It can also be called alcoholic hepatitis. The alcohol impacts the liver cells directly. Moreover, it can also cause cirrhosis or even permanent liver failure.

 

Autoimmune system response

In rare cases, the immune system of a person attacks the liver itself. It leads to inflammation that can be mild to severe according to the infection. Moreover, it s more common in females than in males.

How Is Hepatitis Caused And Some Common Types?

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?

Hepatitis is a medical condition that occurs when an infected person's liver gets inflamed. There are several reasons that can result in hepatitis, including viral infections, heavy alcohol abuse, and autoimmune conditions.

 

Mostly, hepatitis is a result of an infection caused by a virus. Such a condition is called viral hepatitis. Today, we will talk about the three most common types of viral hepatitis diseases:

 ;


	
	Hepatitis a
	
	
	Hepatitis b
	
	
	Hepatitis c
	


 

Hepatitis a

Hepatitis a is a result of hepatitis a virus infection in a person and is relatively uncommon.

 ;

Regions, where hepatitis a is more common, are:

 


	
	Africa
	
	
	Asia
	
	
	Central and south america
	
	
	Eastern europe
	


 ;

How it is transmitted

Hepatitis a virus can be present in the fecal matter and blood of an infected person. Hence, it is transmitted via the oral route, involving ingestion of the virus into a person through the feces.

 

Different ways you can get hepatitis a infection are:

 ;


	
	Having in-person contact with a hepatitis a-infected patient
	
	
	Sexual contact with a person who hosts the virus
	
	
	Consuming contaminated food or drink
	
	
	Eating undercooked shellfish
	
	
	Being near contaminated toilets and diaper changing areas
	


 

Hepatitis b

Hepatitis b is caused by the hepatitis b virus.

 ;

Regions, where hepatitis b is more common, are:


	
	Western pacific region
	
	
	African region
	


 

How it is transmitted

You can contract hepatitis b virus through direct contact with blood or bodily fluids of hepatitis b infected person.

 ;

Different ways you can get hepatitis b infection are:

 


	
	Sexual contact with someone with hepatitis b virus infection
	
	
	Sharing injections and other tools
	
	
	Born to hepatitis b infected parent
	
	
	Direct contact with blood of an infected individual
	
	
	Sharing personal belongings and toiletries like razors or nail clippers.
	


 ;

Hepatitis c

Hepatitis c occurs by the infection caused by hepatitis c virus.

 

Regions, where hepatitis c is more common, are:


	
	Eastern mediterranean region
	
	
	European region
	


 ;

How it is transmitted

Hepatitis c virus is spread through blood and other bodily fluids.

 

Different ways you can get hepatitis c infection are:

 ;


	
	Sharing injections
	
	
	Born to hepatitis c mother
	
	
	Sexual contact with an infected person
	
	
	Piercing or tattooing with unsterilized equipment
	
	
	Injuries with needles pr blades
	
	
	Sharing razors, or toothbrushes
	


The A, B and C of Hepatitis

World sickle cell day is observed annually on the 19th of june to raise awareness of sickle cell-related diseases. It is observed to increase people's knowledge and the understanding required to face the challenges posed by the disease.


 

What is sickle cell disorder (scd)?

Sickle cell disorders or sickle cell diseases are genetic blood disorders that cause an abnormality in the red blood cells. The rbcs turn into sickle-shaped cells that stick together and block the blood flow in the body.


 ;

Types

There are four major classifications of sickle cell diseases-


	
	Hemoglobin ss disease
	
	
	Hemoglobin sc disease
	
	
	Hemoglobin sb+ thalassemia
	
	
	Hemoglobin sb 0 thalassemia
	



 

Symptoms

One can start noticing symptoms of sickle cell in a patient at around 6 years of age. However, they can differ from person to person. Some of the most typical symptoms are-

 ;


	
	Anemia
	


A shortage of red blood cells occurs due to the excessive early dying in 10-20 days. It leads to an oxygen shortage in the body.


	
	Excessive pain
	


Blockage of blood flow due to the change in shape leads to periodic cycles of pain in the body.


	
	Swelling in the body
	


As the blood circulation becomes irregular, swelling becomes a regular phenomenon.


	
	Infections
	


Sickle cell can be damaging to the spleen. It increases the risk of ailments in the body that can be prevented only by antibiotics.


	
	Delayed puberty
	


Oxygen and nutrients carried by the blood are required for growth. As a reason, irregular blood flow can lead to slow growth or delay in puberty.


	
	Vision issues
	


Infected blood vessels carrying blood to the eyes can cause damage to the retina. It can lead to visual problems.


 

Traits and treatment

As sickle cell is genetic, it is suggested to take a test that can detect any trait of the disease. It can prevent any life-threatening risks to the newborn. However, we don't have a complete cure for sickle cell disorders. There are preventive measures that reduce the adversity of the disease to an extent. Procedures like blood transfusions help greatly in minimizing the effects of the disorder.

World Sickle Cell Day: Know All About Sickle Cell Disease

Preeclampsia is a condition that affects women during pregnancy. It is characterized by increased blood pressure and high levels of protein in the urine. Women with preeclampsia also experience swelling in the feet, legs, and arms.

Researchers suspect that excessive body fat or poor nutrition are the primary contributors to preeclampsia and eclampsia.

If left undetected, preeclampsia can lead to a more severe complication, known as eclampsia. Eclampsia can put you and your baby at risk, and can even lead to death (in rare cases).

How do preeclampsia and eclampsia affect the mother?

Preeclampsia and eclampsia can cause a host of complications for the mother, such as the following  

Hellp syndrome   hellp syndrome refers to three different conditions   low platelet count, elevated liver enzymes, and haemolysis. This generally occurs late in pregnancy and affects the processing of rbc, functioning of the liver, and blood clotting.

Seizures

Heart and renal failure

Water in the lungs

Bleeding from the liver

Reversible blindness

Effects of preeclampsia and eclampsia on the baby

Preeclampsia can lead to problems with the placenta in the initial stage of pregnancy. This may pose risks, including the following to the baby  

Lack of nutrients and oxygen, which may prevent the foetus to grow properly

Preterm birth

Stillbirth   this happens when the placenta is separated from the uterine wall

Infant death

Stillbirths are more common when the mother has suffered from a severe form of preeclampsia, like hellp syndrome.

Preeclampsia and eclampsia are linked to a myriad of health issues and life-long challenges for prematurely born babies. These may include cerebral palsy, learning disorders, epilepsy, deafness and blindness.

There is no particular cure for preeclampsia and eclampsia. Treatment, however, depends on how close you are to your due date, and how much the foetus has developed. In the case of mild preeclampsia, your doctor may recommend resting, healthy eating   that limits salt intake   and regular prenatal checkups.
