Other nutritional deficiencies are also worth considering: neutropenia caused by deficiencies of trace elements (such as copper) has also been described, although other haemopoietic cell lines are usually affected. 17 Extreme energy restriction—in patients with anorexia nervosa An eating disorder characterized by abnormally low body weight.Anorexia Nervosa
Does leukopenia increase the risk of infection in anorexia nervosa?
To determine whether patients with anorexia nervosa (AN) and leukopenia have an increased risk of infection, we reviewed the incidence of leukopenia and infection in 68 cases of AN and studied the mechanism of profound neutropenia in one.
What are the effects of neutropenia?
Neutropenia’s effects vary depending on your neutrophil count. With mild neutropenia, you may not experience any symptoms. You may learn you have neutropenia incidentally during a blood test for another condition. Moderate to severe neutropenia may increase your risk of infection. Without treatment, severe neutropenia can be life-threatening.
What is the difference between severe and chronic neutropenia?
The risk of infection is greatest with severe neutropenia, defined by an absolute blood neutrophil count (ANC) less than 0.5 x 10 (9)/L. Severe chronic neutropenia, lasting for more than a few weeks, can be caused by congenital marrow defects, as well as intrinsic and acquired disorders.
How does anorexia nervosa affect the bone marrow?
As a restrictive eating disorder, anorexia nervosa often leads to extreme weight loss and malnutrition. Over a long period of time, sustained nutrient and energy deprivation can seriously impact your body’s essential organ functions. In severe cases, weight loss and malnourishment can even compromise the health of your bone marrow.
Can anorexia cause low white blood cell count?
An estimated one-third of anorexic patients have mild anemia (low red blood cell count). Leukopenia (low white blood cell count) occurs in up to 50 percent of anorexic patients.

What causes neutrophils to be low?
What causes a low neutrophil count? Neutropenia is the result of your body destroying neutrophils before your bone marrow can create more. Causes of a low neutrophil count include: Infection (hepatitis, tuberculosis, sepsis, Lyme disease).
What is an alarming WBC count?
In general, for adults a count of more than 11,000 white blood cells (leukocytes) in a microliter of blood is considered a high white blood cell count.

What does it mean when you have leukopenia?
What is Leukopenia. When a person has leukopenia, it means they are suffering from a shortage of white blood cells, also known as leukocytes. When an adult’s white blood cell count is under 3,500 per microliter of blood, it is generally categorized as an auto-immune disorder. There are several different types of white blood cells, ...

What is the most common cause of neutropenia?
Medications, including chemotherapy. Chemotherapy is one of the most common causes of neutropenia.
How to prevent neutropenia?
These suggestions should help: Wash your hands frequently with soap and water. Wash your hands before and after you eat, after you use the toilet, after touching pets or things outside of your house, and after you cough or sneeze.
What to do if you have febrile neutropenia?
Your doctor will prescribe drugs to fight the infection, such as antibiotics. If you do develop febrile neutropenia, your doctor is likely to admit you to the hospital. You may get your antibiotics intravenously (through a vein). Treating this type of neutropenia is important.
What is the lowest neutrophil count?
By many standards, the lowest acceptable limit for adults is about 1,500 neutrophils per microliter of blood. (Some put the cut-off at 1,800 per microliter.) The range of neutrophil numbers in mild neutropenia is 1,000-1,500; the number in moderate neutropenia is 500-1,000; and the count in severe neutropenia is less than 500.
What is neutropenia in blood?
What is neutropenia? Neutropenia refers to lower-than-normal levels of neutrophils in the blood. A neutrophil is a type of white blood cell that is produced mainly in the bone marrow. White blood cells in general, and neutrophils in particular, are important for infection control in the body.
Why does neutrophilemia happen?
Neutropenia happens for one of these reasons: the neutrophils are used up or destroyed faster than they are produced, or the bone marrow does not make enough neutrophils in the first place. There are many factors that fall into these two categories.
What are the symptoms of neutropenia?
Neutropenia, especially in its mild form, may not have symptoms. If symptoms exist, they could include: 1 Fever 2 Sores 3 Swelling 4 Repeated infections
Causes
Numerous factors may cause neutropenia through destruction, decreased production or abnormal storage of neutrophils.
Cancer and cancer treatments
Cancer chemotherapy is a common cause of neutropenia. In addition to killing cancer cells, chemotherapy can also destroy neutrophils and other healthy cells.
What is isolated neutropenia?
Isolated neutropenia is a common clinical problem seen by primary care physicians and hematologists . The evaluation of neutropenia is dictated by the acuity of the clinical presentation and the duration, age, and clinical status of the patient. In this review, we provide a practical approach to the evaluation of the adult patient with neutropenia, with the major focus on the evaluation of neutropenia in the outpatient setting.
When does neutropenia occur?
Primary autoimmune neutropenia usually occurs during the first year of life. As the name implies, it manifests without other signs or symptoms of an underlying autoimmune disorder. 46 Neutropenia can be moderate to severe and complicated by serious infections. Although the disease is usually self-limited and spontaneously remits within 2 years in about 95% of cases, prophylactic antibiotics and treatment with G-CSF during the neutropenic period are often necessary. 47
What is the cause of autoimmune neutropenia?
It is caused by autoantibodies directed at specific neutrophil antigens. 43 Most of these antigens are surface glycoproteins, including FcγIIIb, CD177, CD11a, and CD11b. 44
What is constitutional neutropenia?
Constitutional or ethnic neutropenia is characterized by mild, chronic neutropenia, usually with an ANC >1000 in a patient with no history of recurrent infections. Constitutional neutropenias are more common in patients of certain ethnic backgrounds, particularly those of Mediterranean and African descents. 1, 2 Neutropenia in populations of African origin is linked to polymorphisms in the Duffy Antigen Receptor Complex ( DARC) gene, 3 but the mechanism by which the Duffy-negative phenotype is linked to neutropenia is unknown, as is the extent to which DARC polymorphisms may be linked to constitutional neutropenia in other ethnic groups. In the vignettes described here, Patient 1 should be diagnosed with constitutional/ethnic neutropenia and not be subjected to further workup. Extensive evaluation of a healthy patient of African descent with an ANC in this range, even in the absence of a past history of CBC panels, is consistently uninformative.
What should be the physical exam for neutropenia?
In otherwise healthy patients with incidental neutropenia, the physical examination should focus on examination for adenopathy or splenomegaly, as well as specific signs of active or prior infection, such as healing skin ulcers or aphthous ulcers. There are few other specific physical examination findings that are helpful.
Is neutropenia congenital or occult?
Newly detected neutropenia in a young patient, particularly one without known previously normal ANCs, raises the possibility of an occult congenital neutropenia syndrome ( Table 1 ). These can be divided into pure neutropenic syndromes and congenital syndromes that include neutropenia as a component of their phenotypes. Of the pure neutropenic syndromes, benign familial, and constitutional neutropenia are universally mild and do not lead to infectious sequelae, whereas patients with severe congenital neutropenia (SCN) have extremely low neutrophil counts or frank agranulocytosis, leading to chronic, severe infections.
Which antibiotics have the highest odds of causing neutropenia?
In the few studies that have corrected for the rate of prescription, a handful of drugs (clozapine, methimazole, sulfasalazine, trimethoprim-sulfamethoxazole, and β- lactam antibiotics as a class) have shown the highest odds ratios for causing serious neutropenia. 36, 37. Table 2. Drugs associated with neutropenia or agranulocytosis.
