Chloramphenicol aplastic anemia. The most serious side effect of chloramphenicol treatment is aplastic anaemia. This effect is rare and sometimes fatal. The risk of AA is high enough that alternatives should be strongly considered.

Acquired aplastic anemia AA is a rare life-threatening bone marrow failure BMF disorder that affects patients of all ages and is caused by lymphocyte destruction of early hematopoietic cells. Diagnosis of AA requires a comprehensive approach with prompt evaluation for inherited and secondary causes of bone marrow aplasia while providing aggressive supportive care.

The choice of frontline. Aplastic anemia appears to occur as a result of chloramphenicols effect on depleting ferritin concentrations in the mitochondria because of the shared ribosomal structures between bacteria and mitochondria making the latter susceptible to the drugs ability to inhibit protein synthesis within the mitochondria. There have also been cases of leukemia developing after aplastic anemia from.

Drugs eg chloramphenicol isoniazid linezolid Copper deficiency. Serum iron studies. Basophilic stippling of RBCs.

Aplastic anemia decrease in or damage to marrow stem cells damage to the microenvironment within the marrow and replacement of the marrow with fat. It results in bone marrow aplasia markedly reduced hematopoiesis CAUSES congenital or acquired Idiopathic Infections and pregnancy certain medications chemicals or radiation damage 33.

Aplastic anemia Chances of survival are poorer for patients with idiosyncratic aplasia caused by chloramphenicol and viral hepatitis and better when paroxysmal nocturnal hemoglobinuria or insecticide toxicity are the probable etiology.

In addition to the hematocrit percentage it is necessary to study other RBC tests such as RBC count hemoglobin MCV MCH MCHC and RDW to identify the type of anemia. A physical examination or complete medical history may reveal possible causes for aplastic anaemia such as exposure to toxins or certain drugs for example chloramphenicol or prior treatment for cancer.

Some cases of aplastic anaemia are temporary while others have lasting damage to the bone marrow. Treatment depends on the cause. Chloramphenicol may decrease the effectiveness of cyanocobalamin.

Chloramphenicol CP D–threo-2-dichloroacetamido-1-pnitro-phenyl-13-propanediol is an effective antibiotic against gram-positive and gram-negative microorganisms. However CP is toxic to hematopoietic system or causes health hazards such as blue baby syndrome bone marrow suppression and aplastic anemia.

Conventionally to achieve a sensitive method of CP. Sideroblastic anemia is suspected in patients with microcytic anemia or a high RDW anemia particularly with increased serum iron serum ferritin and transferrin saturation see Iron Deficiency Anemia Iron Deficiency Anemia Iron deficiency is the most common cause of anemia and usually results from blood loss. Malabsorption such as with celiac disease is a much less common cause.

The enzyme defects responsible for a patients hereditary hemolytic anemia. SICKLE CELL DISEASE. Paracetamol phenacetin pyrazinamide and chloramphenicol.

In sideroblastic anaemia there is a defect in haem synthesis failure to incorporate iron into the haemoglobin molecule. This leads to excess loading of iron to compensate in red cell precursors and into iron stores sometimes. Many drugs can also lower your red blood cell count such as chemotherapy drugs chloramphenicol quinidine and hydrations.
