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?

Urinary tract infections (uti) can occur anywhere in the urinary system   the bladder, kidneys, urethra, and ureter. Most of these infections affect the lower part of the urinary system   urethra and the bladder.

An infection ;confined to the bladder can be frustrating and painful. You may experience pain during urination, and pus or blood in the urine. However, the condition becomes worse if the infection spreads to the upper part of the urinary system, particularly to the kidneys, triggering nausea, ;vomiting, and severe pain in the back.

If uti is left untreated, it can potentially lead to kidney damage   a condition known as pyelonephritis.

How does untreated uti affect the kidneys?

Untreated urinary tract infections can cause the kidneys to swell up and damage them permanently. The infections initially begin in the lower tract of your urinary system. Then the bacteria slowly enter your body through the urethra and begin multiplying and spreading up to the bladder. The bacteria eventually travel to your kidneys through the ureters.

Some people are at higher risk for kidney damage due to urinary tract infections. This includes  


	
	Pregnant women
	
	
	Elderly people
	
	
	People with kidney problems
	
	
	Someone with a weak immune system
	


Signs to watch out for

An untreated infection in the bladder that has spread to the kidneys is associated with symptoms, such as the following  


	
	Chills and ;fever
	
	
	Vomiting and nausea
	
	
	Pain in either side of your lower back
	


You should visit a doctor right away if you notice the above uti symptoms. The condition requires immediate medical intervention in order to prevent damage to your kidneys.

Symptoms of painful utis can be managed by combining medications and lifestyle remedies. Consult a specialist to diagnose the condition early and seek appropriate treatment to avoid complications.

Untreated Urinary Tract Infections And Kidney Damage: Know The Connection

Kidney - prolonged periods of stress can indirectly hurt your kidneys. So you need to be stress free to keep your kidneys healthy.

Stress And Kidney Failure: Are They Connected?

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

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.
