Synonyms and keywords: Elevated white blood cell count; Right-shift leukocytosis; Left-shift leukocytosis

Overview

Leukocytosis is the elevation of the white blood cell count above the normal range (greater than 11,000 per mm3). Leukocytosis is frequently a sign of an inflammatory response, most commonly the result of infection, but may also occur following certain parasitic infections, bone tumors, strenuous exercise, emotional stress, pregnancy, anesthesia, and epinephrine administration. Leukocytosis may be classified into 5 sub-types: neutrophilia (most common), lymphocytosis, monocytosis, eosinophilia, and basophilia. Other classifications include: Left shift or right shift leukocytosis. The pathogenesis of leukocytosis is characterized by the increase of leukocytes (primarily neutrophils), followed by the proliferation and release of granulocyte and monocyte precursors in the bone marrow, which is then stimulated by several products of inflammation including C3a and G-CSF.^[1]

Historical Perspective

Leukocytosis was first discovered by Paul Kautchakoff in 1846.^[1]

Classification

Leukocytosis may be classified into 5 sub-types:^[2]

Leukocytosis may also be classified into 2 groups:^[2]

Left shift (most common)

Immature leukocytes increase
Proliferation and release of granulocyte and monocyte precursors in the bone marrow
Usually stimulated by several products of inflammation including C3a and G-CSF

Right shift

Reduced count or lack of "young neutrophils"
Associated with the presence of "giant neutrophils"

Another variant of leukocytosis is the leukemoid reaction.
The image below demonstrates a graphic figure that illustrates hematopoietic growth factors in leukocytosis.^[3]

Pathophysiology

The pathogenesis of leukocytosis is characterized by:^[2]

An increased release of leukocytes from bone marrow storage pools
Decreased margination of leukocytes onto vessel walls
Decreased extravasation of leukocytes from the vessels into tissues
Increase in number of precursor cells in the bone marrow

Causes

Causes of leukocytosis
Neutrophilic leukocytosis (neutrophilia)	Acute bacterial infections, especially pyogenic infections Sterile inflammation Tissue necrosis Myocardial infarction Burns
Eosinophilic leukocytosis (eosinophilia)	Allergic disorders Asthma Hay fever Drug allergies Allergic skin diseases Pemphigus Dermatitis herpetiformis Parasitic infections Some forms of malignancy Hodgkin's lymphoma Some forms of Non-Hodgkin lymphoma Systemic auto-immune diseases (e.g. SLE) Some forms of vasculitis Cholesterol embolism (transiently)
Basophilic leukocytosis Basophilia	Myeloproliferative disease, e.g. Chronic myelogenous leukemia
Monocytosis	Chronic infections Tuberculosis Bacterial endocarditis Rickettsiosis Malaria Systemic autoimmune diseases, e.g. SLE Inflammatory bowel diseases, e.g. ulcerative colitis
Lymphocytosis	Chronic infections Tuberculosis Brucellosis Viral infections Hepatitis Cytomegalovirus infection Infectious mononucleosis Pertussis Some forms of malignancy, such as lymphocytic leukæmias

Epidemiology and Demographics

Leukocytosis is very common.^[2]

Age

Patients of all age groups may develop leukocytosis.
Normal white blood count differential changes with age.
Leukocytosis in neonates is more common, in comparison to children and adults.^[2]

Gender

Leukocytosis affects men and women equally.

Race

There is no racial predilection for leukocytosis.

Risk Factors

Common risk factors in the development of leukocytosis include:^[2]

Physiological processes (e.g. stress, exercise, pregnancy)
Drugs (e.g. corticosteroids, lithium, beta agonists)
Trauma
Stress

Natural History, Complications and Prognosis

The majority of patients with leukocytosis are initially symptomatic.^[3]
Early clinical features include:^[3]

Common complications of leukocytosis include:^[3]

Prognosis generally depends on the underlying etiologies.^[3]

Diagnosis

Symptoms

Leukocytosis is usually symptomatic.
Symptoms of leukocytosis are often unspecific such as:^[3]

Weight loss
Fevers of unknown origin
Hyperhidrosis
Chronic pain
Fatigue
Dyspnea
Malaise

Obtain history of the following:

Clinical features
Duration (e.g. days, weeks, months)
Remainder of complete blood count

Laboratory Findings

Laboratory findings that are consistent with the diagnosis of leukocytosis involve the ^[3] White blood cell count being above the normal range (greater than 11,000 per mm3).

+'''Leukocytosis''' is the elevation of the white blood cell count above the normal range (greater than 11,000 per mm3). Leukocytosis is frequently a sign of an [[Inflammation|inflammatory response]], most commonly the result of [[infection]], but may also occur following certain parasitic infections, [[bone tumor|bone tumors]], strenuous exercise, emotional stress, pregnancy,  anesthesia, and epinephrine administration. Leukocytosis may be classified into 5 sub-types: [[neutrophilia]] (most common), [[lymphocytosis]], [[monocytosis]], [[eosinophilia]], and [[basophilia]]. Other classifications include: Left shift or right shift leukocytosis. The pathogenesis of leukocytosis is characterized by the increase of leukocytes (primarily neutrophils), followed by the proliferation and release of granulocyte and monocyte precursors in the bone marrow, which is then stimulated by several products of inflammation including [[C3a]] and [[G-CSF]].<ref name="pmid24750674">{{cite journal |vauthors=Chabot-Richards DS, George TI |title=Leukocytosis |journal=Int J Lab Hematol |volume=36 |issue=3 |pages=279–88 |year=2014 |pmid=24750674 |doi=10.1111/ijlh.12212 |url=}}</ref>

+==Historical Perspective==
+*Leukocytosis was first discovered by Paul Kautchakoff in 1846.<ref name="pmid24750674">{{cite journal |vauthors=Chabot-Richards DS, George TI |title=Leukocytosis |journal=Int J Lab Hematol |volume=36 |issue=3 |pages=279–88 |year=2014 |pmid=24750674 |doi=10.1111/ijlh.12212 |url=}}</ref>
-==Overview==
+==Classification==
-'''Leukocytosis''' is an elevation of the white blood cell count (the [[leukocyte]] count) above the normal range. The normal adult human leukocyte count in peripheral [[blood]] is 4.4-10.8 x 10<sup>9</sup>/[[litre|L]]. A white blood count of 11.0 x 10<sup>9</sup>/[[litre|L]] or more suggests leukocytosis. Often, the word refers to an increased [[neutrophil granulocyte]] count, as neutrophils are the main granulocytes.  An increase in [[eosinophil granulocyte]] is known as [[eosinophilia]]. Granulocytosis can be a feature of a number of disease processes including [[infection]], especially [[bacterium|bacteria]]; [[malignancy]], most notably [[leukemia]] (it is the main feature of [[chronic myelogenous leukemia]], CML) and [[autoimmune disease]].  Although it may be a sign of illness, leukocytosis in-and-of itself is not a disorder, nor is it a disease.  It is simply a laboratory finding.
+*Leukocytosis may be classified into 5 sub-types:<ref name="pmid11087187">{{cite journal |vauthors=Abramson N, Melton B |title=Leukocytosis: basics of clinical assessment |journal=Am Fam Physician |volume=62 |issue=9 |pages=2053–60 |year=2000 |pmid=11087187 |doi= |url=}}</ref>
+:*[[Neutrophilia]] (most common)
+:*[[Lymphocytosis]]
+:*[[Monocytosis]]
+:*[[Eosinophilia]]
+:*[[Basophilia]].
-==Epidemiology and Demographics==
+*Leukocytosis may also be classified into 2 groups:<ref name="pmid11087187">{{cite journal |vauthors=Abramson N, Melton B |title=Leukocytosis: basics of clinical assessment |journal=Am Fam Physician |volume=62 |issue=9 |pages=2053–60 |year=2000 |pmid=11087187 |doi= |url=}}</ref>
-Leukocytosis is very common in acutely ill patients. It occurs in response to a wide variety of conditions, including viral, bacterial, fungal, or parasitic infection, cancer, hemorrhage, and exposure to certain medications or chemicals including steroids.  Leukocytosis can also be the first indication of [[neoplastic]] growth of leukocytes.
+:*'''Left shift''' (most common)
+::*Immature leukocytes increase
+::*Proliferation and release of [[granulocyte]] and [[monocyte]] precursors in the [[bone marrow]]
+::*Usually stimulated by several products of inflammation including [[C3a]] and [[Granulocyte colony stimulating factor|G-CSF]]
+:*'''Right shift'''
+::*Reduced count or lack of "young [[neutrophils]]"
+::*Associated with the presence of "giant [[Neutrophil|neutrophils]]"
-==Pathophysiology==
+*Another variant of leukocytosis is the [[leukemoid reaction]].
-The mechanism that causes leukocytosis can be of several forms: an increased release of leukocytes from [[bone marrow]] storage pools, decreased margination of leukocytes onto vessel walls, decreased [[leukocyte extravasation|extravasation]] of leukocytes from the vessels into tissues, or an increase in number of precursor cells in the marrow.

+== Natural History, Complications and Prognosis==
+*The majority of patients with leukocytosis are initially symptomatic.<ref name="wiki">Leukocytosis. Wikipedia. https://en.wikipedia.org/wiki/Leukocytosis Accessed on May 23, 2016 </ref>
+*Early clinical features include:<ref name="wiki">Leukocytosis. Wikipedia. https://en.wikipedia.org/wiki/Leukocytosis Accessed on May 23, 2016 </ref>
+:*[[Fever]]
+:*[[Hyperhidrosis]]
+:*[[Fatigue]]
+*Common complications of leukocytosis include:<ref name="wiki">Leukocytosis. Wikipedia. https://en.wikipedia.org/wiki/Leukocytosis Accessed on May 23, 2016 </ref>

+*Prognosis generally depends on the underlying etiologies.<ref name="wiki">Leukocytosis. Wikipedia. https://en.wikipedia.org/wiki/Leukocytosis Accessed on May 23, 2016 </ref>
-==Leukemoid Reaction==
+== Diagnosis ==
-A leukocyte count of above 25 to 30 x 10<sup>9</sup>/[[litre|L]] is termed as [[leukemoid reaction]]. This occurs as a reaction of healthy bone marrow to extreme stress, trauma, or infection.
-[[Leukemoid reaction]] is different from [[leukemia]] and from leukoerythroblastosis, in which immature blood cells are present in peripheral blood.
+=== Symptoms ===
+*Leukocytosis is usually symptomatic.
+*Symptoms of leukocytosis are often unspecific such as:<ref name="wiki">Leukocytosis. Wikipedia. https://en.wikipedia.org/wiki/Leukocytosis Accessed on May 23, 2016 </ref>
+:*Weight loss
+:*Fevers of unknown origin
+:*[[Hyperhidrosis]]
+:*[[Chronic pain]]
+:*[[Fatigue]]
+:*[[Dyspnea]]
+:*[[Malaise]]
+*Obtain history of the following:
+:*Clinical features
+:*Duration (e.g. days, weeks, months)
+:*Remainder of complete blood count
-==Differential Diagnosis of Causes of {{PAGENAME}} (specifically)==
+=== Laboratory Findings ===
-===By Organ System===
+*Laboratory findings that are consistent with the diagnosis of leukocytosis involve the <ref name="wiki">Leukocytosis. Wikipedia. https://en.wikipedia.org/wiki/Leukocytosis Accessed on May 23, 2016 </ref> [[White blood cell count]] being above the normal range (greater than 11,000 per mm3).
