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?

Environmental factors play a quintessential role in affecting our health. Fresh air, fresh food and fresh water, not only strengthen our body and mind but also make our life worth living. Contrary to this bad environment hampers the quality of life. This is the main reason why people from hill stations or the countryside seem to be healthier than those living in polluted urban cities. Following are the environmental factors that affect your health:

Polluted air

The health effects of polluted air are several. Not many people know that one-third of the deaths are caused because of strokes, lung cancer and heart failure. Air pollution is the chief reason behind these chronic ailments. The other life-threatening diseases caused by polluted air is- asthma or bronchitis. Smoke from machines, vehicles outside, and stoves, the burning of fuels inside can cause breathing problems and wheezing. 

Dirty environment

A dirty environment often leads to the breeding of insects and bacteria that become carriers of life-threatening diseases such as dengue, typhoid, diphtheria, malaria, and so on. Most of the diseases mentioned here are caused by mosquitoes that thrive on stagnant water.

Toxic food ;

The environmental quality of a region has a direct impact on the food produced in that area. Both vegetarian and non-vegetarian food faces the danger of becoming toxic if the environment it is being grown in is polluted. For eg- chemical wastes that are often dumped in water bodies cause the seafood in that area to become highly toxic.

Chemical pollutants

Cancer nowadays is becoming a household disease. The major reason behind this is that technological development has brought new categories of pollutants. Many of these contain chemicals and compounds that are carcinogenic in nature. This ultimately leads to the development of cancer in most people. 

Climate change and natural calamities

Change in climate disrupts the functioning of nature in many ways that further impact the health of humans. These changes include- the natural temperature of the planet, heavy rainfalls and sandstorms. The numerous impacts of climate may result in a high risk of nervous and respiratory diseases. ;

Hence protecting the environment is extremely important for the life of a human being. The change will come after taking small steps. Numerous small steps can really make a difference.

Environmental Factors That Affect Health

People suffering from sickle cell disease (scd) usually start showing symptoms very early. They can appear to show up even during the first year of life. Symptoms of a sickle cell vary from one person to another and can be mild to serious depending on the condition.

 

Sickle cell disease is a health condition that worsens with time. Despite the absence of any full-proof solution, some treatments prevent further complications. These treatments can help patients receive aid for a lifetime. Simply said, sickle cell diseases can be managed medically.

 ;

Treatment

Treatment in a sickle cell patient depends on the severity of the symptoms. Preventing complications and relieving pain is the primary aim of the diagnosis. They can range from medications to blood transfusions.

 

Concerns

Some of the concerns that need to be taken care of during the treatment of scd are-

 ;


	
	Prevent painful scenarios
	


A painful episode or sickle cell crisis can be avoided by consuming sufficient fluids, wearing warm clothing, and staying away from sudden temperature changes.

 


	
	Avoid infections
	


Children with sickle cell anemia are made safe from infections by using penicillin. Adults with anemia might need to take penicillin all their lives. Doctors should ensure that all vaccinations in children and adults are periodically done to avoid any infections. However, during the covid-19 pandemic sickle cell patients should take extra care.

 ;

Medications

While there can be numerous ways to manage sickle cell treatment, medications help in a significant way. Some of the prescribed medicines are-


	
	Hydroxyurea- it reduces the frequency of sickle crises. Pregnant women should stay away from this according to experts.
	
	
	Crizanlizumab- this drug injected into the patient can help reduce the sickle crises in adults and children over the age of 16.
	
	
	Voxelotor- it is an oral drug used in children over 12. It lowers the risk of anemia by improving blood flow.
	
	
	Pain-relievers- narcotics to prevent excessive pain can also be used during the treatment.
	


 

Surgical procedures


	
	Blood transfusion
	


It is used to prevent stroke and other related complications in patients. This can increase the number of red blood cells in the body that can help reduce the symptoms.

 ;


	
	Stem cell transplant
	


It is also called a bone marrow transplant and is used to replace affected bone marrow with a healthy one. This procedure is carried out between matched donor and recipient. Although it is a known cure for sickle cell disease, various risks involved make it a less used practice.

 

Can Sickle Cell Be Cured?

Thyroid cancer refers to the type of ;cancer that originates in the thyroid gland. Cancer develops when the cells in your thyroid gland begin multiplying uncontrollably to form malignant tumours.

What leads to the development of cancer in the thyroid glands is not clearly known. However, a combination of environmental factors and genetics could be a leading cause of cancer.

Thyroid cancer is the sixth most common cancer in women, and usually affects those in their 20s and early 30s.

Types of thyroid cancer

Four types of thyroid cancer are prevalent, which are  


	
	Papillary thyroid cancer   ;this is the most common type of thyroid cancer. Cancer typically develops in one of the two lobes in the thyroid gland, and gradually spreads to the lymph nodes in your neck.
	
	
	Follicular thyroid cancer   ;the second most common type is the follicular thyroid cancer. Here the disease spreads to other body parts and organs, like the bones or lungs rather than the lymph nodes.
	
	
	Medullary cancer   cancer starts from the c-cells of the thyroid gland, which usually produce a hormone called ;calcitonin. The disease can spread to the lungs, liver, or lymph nodes even before a nodule is discovered.
	
	
	Anaplastic thyroid cancer   this form of cancer is rare but aggressive. It develops from an existing follicular or papillary cancer and spreads to other parts of the body faster than any other type of thyroid cancer.
	


Symptoms to watch out for

The symptoms of thyroid cancer depend on its type. Although there are no observable symptoms in the initial stage, you might be able to spot some changes in your body as cancer progresses. These symptoms include:


	
	A lump or mass in the neck that can be felt through the skin
	
	
	Change in voice   ;hoarseness
	
	
	Pain in the throat and neck
	
	
	Difficulty in swallowing
	
	
	Swelling of the lymph nodes in your neck
	


Diagnosis and treatment

The following tests/procedures can help detect thyroid cancer early  


	
	Blood test
	
	
	Ultrasound
	
	
	Biopsy
	
	
	Imaging tests
	
	
	Genetic testing
	
	
	Pet scan
	


Once cancer is diagnosed, appropriate treatment will be prescribed depending on the stage. Primary treatment options include  


	
	Chemotherapy ;  medications are infused through veins to kill cancer cells
	
	
	Radiation therapy   high-energy radio beams are directed to destroy cancer cells
	
	
	Radioactive ;iodine   large doses of radioactive iodine are given orally
	
	
	Targeted therapy   medications are given to attack certain vulnerabilities in the cancer cells
	
	
	Surgery ;  complete or partial removal of the thyroid gland or the lymph nodes
	


Prior to the treatment, your doctor will discuss the treatment plan specific to your diagnosis. Thyroid cancer is curable if detected at the right time. Therefore, do not lose hope and consult a specialist as early as possible.

Thyroid Cancer: Causes, Symptoms, And Treatment

Hepatitis- related to an inflammatory condition of the liver. It occurs mainly due to infection caused by viruses but there are other possible causes as well. Hepatitis can be temporary or viral. Temporary hepatitis, which is acute in nature, gets resolved on its own. Viral hepatitis can be of five types, a, b, c, d, and e.

Symptoms of hepatitis

Hepatitis, in its initial phase, is called the acute phase. The following symptoms along with mild flu are visible:

Loss of appetite
Fatigue
Joint pains
Pain in the abdomen
Nausea
Weight loss
Jaundice
Though this phase is not really dangerous for some patients, it can result in liver failure leading to death.

How is hepatitis diagnosed?

Physical examination
Laboratory tests
Imaging tests


Treatment for hepatitis

Treatment options for different types of hepatitis are:

Hepatitis a: this doesn t require treatment as it is short-term in nature. In case the symptoms cause a lot of discomforts, then bed rest is recommended. The vaccine is available to prevent this infection.

Hepatitis b: acute hepatitis b doesn t require treatment either. Its chronic form can be treated with antiviral medications. This can be prevented with vaccination.

Hepatitis c: this type of hepatitis, both in its acute and chronic forms, is treated through antiviral medications.

Hepatitis d: according to a study in 2013, a drug known as alpha interferon is used to treat this type of hepatitis. Unfortunately, this only comes to the rescue of 25-30% of people.

Hepatitis e: this acute form of hepatitis gets resolved on its own. Adequate rest, drinking a sufficient amount of water, and taking enough nutrients in their food are some of the ways to get healed from this disease.
