Gene Therapies for Sickle-Cell Disease

Two gene therapies for sickle-cell disease (SCD) are:

1. Lyfgenia from Bluebird Bio

2. Casgevy by Vertex Pharmaceuticals and Crispr Therapeutics

This transformative therapy depend on Crispr gene-editing technology and uses the patients' own blood stem cells. The DNA is cut at targeted areas, and the faulty DNA deleted, added or replaced. The modified blood stem cells are transplanted back into the patient where they multiply within the bone marrow.

The gene therapy is a one-time treatment. 

This therapy is approved for patients aged 12 and older.

Follicular lymphoma

Cancer happens when the immune system is weak and the proliferation rate of certain cell type accelerates and remains unchecked. By the time a tumour is discovered, it has already started to metastasized to other parts of the body (stage 4). One good example of this type of cancer is follicular lymphoma.

The immune system is the body's defense system to thrash out pathogens (bacteria, fungus and viruses) when they come into contact with the body. These pathogens can enter the body in many ways. Dirty contaminated hands and feet, catching someone else's sneezes and coughs, use of contaminated articles of a sick person, etc can cause human to contract pathogens.

There are times when the immune system is good and strong. And there are times when the immune system is a bit weaker and not at its best. When the immune system is weak, changes in the cells, tissues and organs are not cleared or corrected, and cancerous growth go unchecked.

What is blood cancer?

Huffington Post, UK: Blood cancer

Blood cancer:

  • is an umbrella term
  • is a group of cancers that affect the blood, bone marrow and lymphatic system
  • there are 137 types (eg: leukaemia, lymphoma, multiple myeloma)
  • they are often diagnosed late
  • late diagnosis affects a patient's survival (life span)
  • blood cancer rate: 1 in 25 persons in UK (4%)
  • how common is blood cancer? 5th most commonly diagnosed cancer in UK

The lymphatic system comprises 

  1. lymphatic tissue (found in the stomach, bowel, eye and thyroid gland)
  2. white blood cells (called lymphocytes)
  3. lymphatic organs (such as the bone marrow, tonsils, thymus, testicles, spleen and lymph nodes).

What is lymphoma? What is Non-Hodgkin Lymphoma (NHL)? 

CDC: Lymphoma, Non-Hodgkin Lymphoma, Causes, Symptoms

St Baldrick's Foundation, UK: Non-Hodgkin Lymphoma

Lymphoma is a type of cancer that affects the lymph glands or other organs in the lymphatic system. There are different types of lymphoma. The 2 main types are: 

  1. Hodgkin lymphoma (a cancer of a type of white blood cell called lymphocytes)
  2. non Hodgkin lymphoma (NHL) (a cancer of the lymphatic system).


What are the causes of lymphoma?

CDC: Lymphoma, Non-Hodgkin Lymphoma, Causes, Symptoms

The cause of lymphoma is unknown. It develops because of changes in the genes of a lymphocyte. These changes affect how the cell grows and divides, or prevent it from dying when it normally should. Thus, the cancer cell lives on without ever dying.


What are the symptoms of lymphoma?

Cancer has symptoms. Symptoms in lymphoma can be apparent or not. Patients may experience some of the following:

  1. weight changes (rapid weight loss over a short time, losing a lot of weight, eg losing 15 kg in 2 weeks)
  2. appetite changes (refusing normal meals and usual food)
  3. heavy sweating (night sweats, profuse sweating at night, pillows and bedsheet are drenched)
  4. fever (extremely high fever overnight for a week), 
  5. tiredness, fatigue (not much energy to get up except to lie down and continue sleeping)
  6. restlessness, blank mind, unthinking
  7. swollen lymph nodes (here and there, off and on, painful or painless, varying sizes, ballotable, at groin, upper arm and neck),
  8. feeling funny in the groin and armpit due to swollen lymph nodes
  9. legs affected (walk funny, limping, cannot lift up one leg fully)
  10. weird looking neck and upper arm (where lymph nodes are swollen and are visible)
  11. difficulty swallowing (when trying to drink or eat something because the swollen lymph nodes are blocking and pressing on the blood vessels and nerves in the throat and neck)
  12. more noticeable lymph nodes (feeling the lymph nodes are increasing in number with time)
  13. more lymph nodes detected (progressing upwards towards the neck and head region)
  14. large swollen lymph nodes in the neck or encircling the neck
  15. difficulty breathing, shortness of breath (SOB) or feeling breathless (the swollen lymph nodes have spread to the lungs and neck region and can block the oesophagus and trachea
  16. infected lymph nodes (bacteria survive in the swollen lymph nodes which are difficult to treat)
  17. skin changes (worsening itchy skin, will not disappear with calamine lotion, nothing seems to reduce the skin itch)
  18. irritating dry coughing to clear the throat (when trying to remove smelly pus from the swollen or enlarged tonsils)
  19. abdominal pain (constant abdominal pain after food intake, lump in the abdomen)
  20. food cannot go down normally (need to push food down, can only eat minimally)
  21. bloatedness (constantly feeling bloated but not burping)
  22. discomfort when seated (due to large abdomen because of enlarged liver or spleen)
  23. headaches (if lymphoma starts in the brain or cannot fart)
  24. difficulty thinking 
  25. difficulty moving limbs and body parts (legs, arms, and neck)
  26. changes in personality and moods (due to dissatisfaction, frustration, unhappiness and depression, inability to do much physical activities as before cancer)
  27. seizures


What is follicular lymphoma?

What happens in follicular lymphoma?

Some cells of the immune system can proliferate voraciously and become massive. The patient ends up with a big hard abdomen. Some cancer grows a bit more slowly but given time, it too can become massive, and give a big hard abdomen.

When a cancerous growth becomes massive, it can occupy all available spaces in the abdomen, pushing on nearby organs and blood vessels away from their normal orientation and location. 

This means, the major aorta that supplies the legs can be occluded and there is no blood supply to the legs ... walking can become arrested. 

The diaphragm is pushed upwards by the massive cancerous growth, and disrupts lymphatic flow ... causing backflow and unequal build up of lymph in the pleural spaces of both lungs. 


How is pleural fluid drained?

The lungs can easily get filled with a litre of lymph exudate each pleural space per 8 hours collection. Lymph is drained from the pleural space by a tube. The tube is of 2 types: 

  1. Pigtail tube (8 months) with collection canister, and 
  2. Intraperitoneal catheter (IPC), also called chest tube (7 months) with urine bag for collection of pleural fluid.


What is a pigtail?

Initially because of the large volume of lymph that must be drained daily every 8 hours, a pigtail is installed by the Interventional Radiology (IR) Unit, under local anaesthesia and takes 15-20 minutes. This is a very painful procedure. The initial lymph drained in bloody and then becomes milky, then clear amber with time. The pigtail is left in use for about 8 months. The exit port can hurt extremely painful. Bandage must be replaced daily.


What is IPC?

Once the fluid in the pleural spaces has reduced, another type of tube is used. This is the IPC or chest tube. It is installed in the ward treatment room by the Chest Specialist and her team (about 5 people). The chest tube is left in place for a few months (7 months) till the pleural fluid is reduced to less than 50 ml overnight. 


When and how is the chest tube removed?

When the pleural fluid is much reduced (less than 50 ml overnight), the chest tube is then removed surgically in the treatment room. It is removed by pulling it out quickly and strongly ... the patient feels a shocking vacuum. The incision is then stitched with 8 stitches for complicated removal where the tissues have attached to the chest tube. Chest tube removal is 20 minutes in a simple removal. However, a complicated chest tube removal may take up to an hour. 


How do you care for the incision site after chest tube/IPC removal?

A light bandage with waterproof cover is applied to protect the stitches. This bandage is replaced daily for a week or two. Then daily cleaning without bandage should suffice. 


What is a keloid?

Keloid will develop in some cases. The scar is itchy and painful even at 8 months post-op when sweat accumulates and soak the scar.

What were the difficulties of cancer diagnosis and complications of cancer?

This particular cancer was not detected at first until much later. It presented as a renal problem (hyperkalaemia). Correcting and investigating Hyperkalaemia resulted in an accidental finding of massive growth in ultrasound of the abdomen. A CXR was performed for SOB. A CT guided biopsy was performed and revealed Follicular lymphoma. The accumulated pleural fluid was drained from both lung, major from right lung. Pigtail was installed 4x for 8 months. Then IPC was installed for 7 months. IPC was removed after minimal pleural fluid remained in the right lung. The pleural fluid was less in the left lung and was drained only once using pigtail. CA 19-9 for ovarian cancer was suspected but was negative. Chemotherapy with dual monoclonal antibodies was performed for 6 cycles at 28 days apart. CT-NATP was done after every 3 chemo sessions. Stimulating growth factor was given after 4 days starting each chemo. The abdominal mass was partially reduced after 6 chemo cycles. Maintenance chemo with Rituximab was continued (for an additional 2 years at 2 months apart).


Treatment depends on:

  1. type and stage of cancer
  2. health of patient
  3. patient's will power to survive cancer 
  4. faith in treatment modes
  5. consent


Treatment modes and drugs will depend on type and stage of cancer, patient's immunity, affordability and consent. There are a few treatment modes available (as of 16 December 2021):

  1. Chemotherapy (using monoclonal antibodies: 1. Rituximab (Ritu) and 2. Bendamustine (Benda))
  2. Radiotherapy (using tagged radioisotopes)
  3. Steroids
  4. Biological drugs (proteins which affect functions of the cancer cells and control cancerous growth)
  5. Stem cell (homologous stem cells are obtained by harvesting patient's own blood for stem cells)
  6. Bone marrow transplant (BMT)
  7. Microencapsulation (in future; based on research at ISS, NASA)

Longevity

 Longevity is subjective and means different things in different communities. Short life span will mean rushing everything into the short time span. Long life means there is no need to rush things as there is time to do everything at leisure.

What to study in people who live long (long livers)?

  • Food: food composition, diet and nutrition, natural food products
  • Food KAP: Knowledge, activities, and practices
  • Level of eating food: good amount, extra amounts, moderate amounts
  • Activities: daily, weekly, monthly
  • Social status: alone (solo), together (family, small group, large groups)
  • Stress relivers: how do people relief stress?
  • Brain and senility: how active is the brain?, cognitive function (count, group, class etc)
  • Attitude: calmness, level of stress
  • Ecology: level of air pollution 
  • Celebrations: what do they celebrate?
  • Rest: how much rest is needed?
Age of participants:
  • young livers
  • middle-age livers
  • elderly livers
  • long livers
Study questions:
  1. How old are you?
  2. How old is the youngest in your family?
  3. How old is the eldest in your family?
  4. How long do you sleep?
  5. How do you start your daily activities?
  6. What do you do daily?
Health check
  1. Heart
  2. Muscle
  3. Brain
How to study communities?

  1. Group A: Communities which lived to between 40 and 50. Some lucky ones lived beyond 50.
  2. Group B: Communities which lived to between 50 and 60. Some lucky ones lived beyond 60.
  3. Group C: Communities which lived to between 60 and 70. Some lucky ones lived beyond 70.
  4. Group D: Communities which lived to between 60 and 70. Some lucky ones lived beyond 80.

Penicillin

The Penicillium mold (fungus) was accidentally discovered by Alexander Fleming in his laboratory in 1928. The fungus produced pencillin which blocked the growth of Staphylococcus (a bacteria). Penicillium is important for the production of penicillin, an antibiotic.

Penicillin took a long time to come on the market. It was made available by the end of the Second World War (1945), and helped to save soldiers on the battle field from influenza (flu), who would otherwise die. Thus, penicillin was hailed as a saviour of the soldiers involved in the great war. More soldiers were returning after the war due to penicillin. Even postal boxes had penicillin posters draped them, with the words, 'Penicillin cures gonorrhea in 4 hours'.

While the initial green fungus (Penicillium notatum) was grown in petri dishes, the fungus grows well on orange skin. It also grows well on orange skin kept in the fridge and on stale bread. However, higher yields of penicillin comes from Penicillium chrysogenum grown on the flesh of cantaloupe (a fruit like a melon, with orange flesh).

Penicillin allergy is uncommon but people who have severe allergy to penicillin have severe itch after trying oral penicillin or died after being injected with penicillin. Doctors will always ask parents or patients before prescribing or administering penicillin. You should know whether you are allergic to penicillin or otherwise.

Commercial penicillin is produced by fermentation, which is done in batches using cultured media from microbial sources (not animal sources). Corn steep liquor is mixed with glucose (as carbon source) and first sterilised in tanks. The fungus is added to the fermentation tanks and produces penicillin as a natural secondary product (metabolite). The fungus is then separated from the penicillin (in the fermentation broth). The penicillin is then purified for use as medicine. The fungus is recycled to produce another batch of penicillin.

There was one poster which said, 'Try Penicillin. Made from mold, you can get this drug from your doctor or prepare it yourself'. It is alright to try and see Penicillium growth on orange skin and/or bread at home. However, care has to be taken not to contaminate other food kept at home or stored in the fridge. Care has also got to be taken not to breathe in the spores released from the fungus. If you can smell the fungus, the spores are already inside you! Keep your distance or use a face mask. Take pictures and destroy the fungus by burning it outside your home. Take precaution when you use fire.
