Neutrophils play a vital role in protecting against infection, so the duration and severity of neutropenia directly correlate with the total incidence of all infections, including those that are life threatening. (medscape.com)
[ 3 ] Major causes of acquired neutropenia are infection, drugs (through direct toxicity or immune effects), and autoimmunity. (medscape.com)
Agranulocytosis, also known as agranulosis or granulopenia, is an acute condition involving a severe and dangerous lowered white blood cell count (leukopenia, most commonly of neutrophils) and thus causing neutropenia in the circulating blood. (wikipedia.org)
To be precise, neutropenia is the term normally used to describe absolute neutrophil counts (ANCs) of less than 500 cells per microlitre, whereas agranulocytosis is reserved for cases with ANCs of less than 100 cells per microlitre. (wikipedia.org)
The duration and severity of neutropenia directly correlate with the total incidence of all infections and of those infections that are life threatening. (medscape.com)
Tuberculosis (see the image below) is one type of infection that may cause neutropenia. (medscape.com)

If neutropenia is not treated, bacterial infections can lead to life-threatening complications such as bacterial shock or bacterial contamination of the blood (sepsis. (orthopedicshealth.com)
Drugs with this characteristic include valproic acid, carbamazepine, and the beta-lactam antibiotics. (orthopedicshealth.com)
Radioactive iodine2
Reduction of thyroid hormone is accomplished by use of drug therapy, surgical subtotal thyroidectomy, or treatment with radioactive iodine (RAI). (medscape.com)
Patients with GD are treated with any of the following: antithyroid drugs (ATDs), radioactive iodine (RAI) therapy, or thyroidectomy. (e-jyms.org)
Vulnerability to infection is extremely high in patients with agranulocytosis, which is the virtual absence of neutrophils in peripheral blood, with ANC typically lower than 100/μL. (medscape.com)
Although the reaction is generally idiosyncratic rather than proportional, experts recommend that patients using these drugs be told about the symptoms of agranulocytosis-related infection, such as a sore throat and a fever. (wikipedia.org)
Instruct patients treated with antithyroid drugs as to possible adverse effects and the need for close follow-up. (medscape.com)
As neutrophil levels decrease, the susceptibility of patients with acquired agranulocytosis to bacterial infections becomes even greater. (orthopedicshealth.com)
Continuing drug treatment for an extended time is now encouraged in patients with a high possibility of remission with low-dose MMZ. (e-jyms.org)
Neutrophils1
In agranulocytosis, the concentration of granulocytes (a major class of white blood cells that includes neutrophils, basophils, and eosinophils) drops below 200 cells/mm3 of blood. (wikipedia.org)
Acute1
In rare cases of acute acquired agranulocytosis, destructive action of certain white blood cell antibodies (leukocyte isoantibodies) may be induced by certain drugs such as phenylbutazone, gold salts, sulfapyridine, aminopyrine, meralluride, and dipyrine. (orthopedicshealth.com)
Disorder3
Acquired agranulocytosis is a rare, drug-induced blood disorder that is characterized by a severe reduction in the number of white blood cells (granulocytes) in the circulating blood. (orthopedicshealth.com)
The treatment of acquired agranulocytosis includes the identification and elimination of drugs or other agents that induce this disorder. (orthopedicshealth.com)
Fetal effects vary with the disorder and the drugs used. (msdmanuals.com)
Severe2
It is a severe lack of one major class of infection-fighting white blood cells. (wikipedia.org)
Agranulocytosis implies a more severe deficiency than granulocytopenia. (wikipedia.org)
Symptoms2
Symptoms may be improved by treatment with beta-blocking drugs. (medscape.com)
The first symptoms of acquired agranulocytosis are usually those associated with a bacterial infection such as general weakness, chills, fever, and/or extreme exhaustion. (orthopedicshealth.com)
People with this condition are at very high risk of serious infections due to their suppressed immune system. (wikipedia.org)
In some instances, the action of some drugs or chemicals suggests that the immune system is involved. (orthopedicshealth.com)
Bacterial2
Lung infections are usually bacterial or fungal pneumonias. (medscape.com)
People with acquired agranulocytosis are susceptible to a variety of bacterial infections, usually caused by otherwise benign bacteria found in the body. (orthopedicshealth.com)
Granulocytopenia1
for these reasons, granulocytopenia is a more etymologically consistent term, and as such, is sometimes preferred to "agranulocytosis" (which can be misinterpreted as "agranulocyt-osis", meaning proliferation of agranulocytes (i.e. lymphocytes and monocytes). (wikipedia.org)
Sudden1
Agranulocytosis may be asymptomatic, or may clinically present with sudden fever, rigors and sore throat. (wikipedia.org)
Cases1
We appreciate and agree with the comment by Asawa et al that "the leukocyte differentiated count, not only routine white blood cell count is critically important for the correct diagnosis of antithyroid drug-induced agranulocytosis in some cases. (jamanetwork.com)
Medications2
However, among the drugs to which a patient may be sensitive are several used in the treatment of cancer (cancer chemotherapeutic agents) and others used as antipsychotic medications (e.g., clozapine). (orthopedicshealth.com)
Antibiotic medications may also be prescribed if there is a positive blood culture for the presence of bacteria or if a significant local infection develops. (orthopedicshealth.com)

Cutting agent1
The Drug Enforcement Administration reported that, as of February 2010, 71% of seized cocaine lots coming into the US contained levamisole as a cutting agent. (wikipedia.org)
Albendazole, marketed as Albenza, Eskazole, Zentel, Andazol and Alworm, is a member of the benzimidazole compounds used as a drug indicated for the treatment of a variety of worm infestations. (parasitetesting.co.uk)
Total1
Consequently, agranulocytosis is sometimes described as "no granulocytes", but a total absence is not required for diagnosis. (wikipedia.org)
Dosage1
500mg.org gives you the possibility to purchase cheap Glipizide 2,5, 5, 10 mg online and also find out more about Glipizide side effects, dosage information and drug interactions. (llclinic.com)
Correct1
After the correct clinical evaluation, oral antidiabetic drugs were added. (bvsalud.org)
Important1
For the long-term management of recurrent GD, it is important to induce remission by evaluating the patient's drug response, stopping ATDs at an appropriate time, and actively switching to surgery or RAI therapy, if indicated. (e-jyms.org)
Your personal doctor may prescribe such a medicine in conjunction with sulfonylureas insulin, or possibly a category of drugs generally known as thiazolidinediones. (llclinic.com)
Remains1
Despite this, "agranulocytosis" remains the most widely used term for the condition. (wikipedia.org)
The New York State Department of Health found that the effectiveness of Pfizer's vaccine against Covid infection plummeted from 68% to 12% for kids in that age group during the omicron surge from Dec. 13 through Jan 24. (covid19reporter.com)
