Does chloramphenicol cause bone marrow suppression?

Chloramphenicol dose-related bone marrow suppression is observed in virtually all patients who receive the drug. This expected effect of chloramphenicol is due to its ability to reversibly inhibit mitochondrial protein synthesis and ferrochelatase found on the inner membrane of mitochondria.

Is chloramphenicol reversible?

The incidence of aplastic anemia is rare but the consequences are severe because it is irreversible. The risk of human exposure led to the ban of chloramphenicol use in food animals.

What antibiotics treat aplastic anemia?

Antithymocyte Globulin

It is typically used with cyclosporine as the first-line immunosuppressive therapy (IS) to treat patients with acquired aplastic anemia.

What is the most toxic reaction to chloramphenicol?

Blood Dyscrasias
The most serious adverse effect of chloramphenicol is bone marrow depression. Serious and fatal blood dyscrasias (aplastic anemia, hypoplastic anemia, thrombocytopenia, and granulocytopenia) are known to occur after the administration of chloramphenicol.

How long does chloramphenicol stay in your system?

Half-life in adults with normal hepatic and renal function is 1.5 – 3.5 hours. In patients with impaired renal function half-life is 3 – 4 hours. In patients with severely impaired hepatic function half-life is 4.6 – 11.6 hours.

Can chloramphenicol cause leukemia?

Chloramphenicol is reasonably anticipated to be a human carcinogen, based on limited evidence of carcinogenicity from human cancer studies. Numerous case reports have shown leukemia to occur following chloramphenicol-induced aplastic anemia (IARC 1990).

Is bone marrow suppression reversible?

Myelosuppression is usually reversible; however, it may take several months for the white blood cell count to return to the normal range, and some patients remain relatively leukopenic. Irreversible, fatal bone marrow suppression has been reported in patients receiving chlorambucil for rheumatic disease.

Is drug-induced aplastic anemia reversible?

In some cases, aplastic anemia is a temporary side effect of a medication. It can be reversed if exposure to the cause is stopped.

Can chloramphenicol cause aplastic anemia?

Although chloramphenicol continues to be the leading single cause of drug-induced aplastic anemia, little progress has been made in elucidating the mechanism of its toxic effect. The reversible erythroid depression occurring concurrently with chloramphenicol therapy is a pharmacologic effect.

What is the toxic effect of chloramphenicol?

Chloramphenicol can be fatal in an overdose; this usually occurs with intravenous administration of the drug and is more likely to affect infants. Symptoms of poisoning include nausea and vomiting, abdominal distension, metabolic acidosis, hypotension, hypothermia, cardiovascular collapse, and coma.

Why was chloramphenicol discontinued?

Chloramphenicol can produce some serious adverse effects, including aplastic anemia, neurotoxicity, and some cancers. In 1991, the United States discontinued the use of the oral formulation because of its association with aplastic anemia.

What is the management of bone marrow suppression?

Treatment and prevention to manage bone marrow suppression
Your child should avoid strenuous activity, contact sports or heavy lifting. Avoid having your child blow their nose or forcefully cough. Avoid harsh, raw vegetables, or foods with rough surfaces in your child’s diet. Avoid allowing your child to consume …

Is bone marrow suppression serious?

Myelosuppression is not usually life threatening in itself, but if a person has fewer white blood cells, they have an increased risk of developing a potentially life threatening infection or bleed.

How do you reverse bone marrow suppression?

If you begin to experience myelosuppression from bone marrow failure, doctors may recommend a transplant or transfusion to replenish blood cells. An alternative to transfusions is growth factor injections. These injections are natural chemicals that help boost bone marrow performance.

What does chloramphenicol do to the body?

Chloramphenicol is used in the treatment of infections caused by bacteria. It works by killing bacteria or preventing their growth.

Can bone marrow suppression be reversed?

Can bone marrow damage be reversed?

Bone marrow failure is most often not reversible.

Can bone marrow suppression be cured?

Bone marrow suppression due to azathioprine can be treated by changing to another medication such as mycophenolate mofetil (for organ transplants) or other disease-modifying drugs in rheumatoid arthritis or Crohn’s disease.

How can I increase my bone marrow naturally?

You can keep your bone marrow healthy by: Eating a diet rich in protein (lean meats, fish, beans, nuts, milk, eggs). Taking vitamins (iron, B9, B12). Treating medical conditions where bone marrow abnormalities are a side effect.

What helps bone marrow recovery?

Bone Marrow Transplant Recovery at the Hospital
While you recover at the hospital, you might need: Medicine to keep your immune system low to decrease the chance of transplant rejection. Antibiotics to prevent infection. Platelets, plasma, and red blood cell transfusions to prevent bleeding and anemia.

What happens if your bone marrow is suppressed?

Bone marrow suppression can cause extreme tiredness (fatigue), infection, and bleeding.

What foods repair bone marrow?

You can keep your bone marrow healthy by: Eating a diet rich in protein (lean meats, fish, beans, nuts, milk, eggs). Taking vitamins (iron, B9, B12).

What vitamin is good for bone marrow?

Vitamin D
The bone marrow disease myelofibrosis is stimulated by excessive signaling from vitamin D and immune cells known as macrophages, reveals a Japanese research team. These findings could help to develop alternative treatments that do not target problem genes.

How can I restore my bone marrow naturally?

Eating protein, iron and B vitamins will help bone marrow do its job.
…
Each type of blood cell has an important function:

Red blood cells transport oxygen throughout the body.
White blood cells support the immune system to fight infection.
Platelets are required for proper blood clotting.

What stimulates bone marrow growth?

This may happen when the oxygen content of body tissues is low, if there is loss of blood or anemia, or if the number of red blood cells decreases. If these things happen, the kidneys produce and release erythropoietin, which is a hormone that stimulates bone marrow to produce more red blood cells.
