Presentation
The major clinical feature of leukopenia is infection, often serious and more likely as neutrophil counts fall. The manifestations mainly depend upon the degree of leukopenia or rather neutropenia. The clinical features seen are due to the bacterial infections. It is necessary to consider [7] neutrophil count as this is the most abundant type of white blood cells and an important marker of infection.
The main symptoms of leukopenia are:
- Anemia: A low level of hemoglobin occurs with decrease in white blood cells. The reason is not yet clearly known but can be due to blood dyscrasias and an increased number of red blood cells that are required for oxygen to be circulated.
- Fever: Due to decrease in level of immunity and white blood cells, patient is at a higher risk of opportunistic infections. Fever is a strong indication of some infection.
- Pneumonia: Once infection enters the body, it is most likely to infect lungs. It could be viral or bacterial.
Other symptoms include headache, menstrual irregularities, thrombocytopenia , stomatitis and a variety of other infections in literally any part of the body. A patient may show no symptom other than mouth ulcers suggesting of some infection.

Some sources of quality protein are fish, eggs, poultry, beef, milk, Greek yogurt and beans. If your diet is poor, or you're having trouble eating, you can take a multivitamin or supplement with vitamin B12 and folate. [nebraskamed.com]
If you have neutropenia, you should avoid raw meat, eggs and fish, moldy or expired food, unwashed or moldy fruit and vegetables, and unpasteurized beverages, including fruit and vegetable juice, beer, milk, as well as unpasteurized honey. [oncologynutrition.org]
Avoid uncooked eggs, raw or undercooked meats, poultry, fish and seafood. These foods can contain harmful organisms. Live plants can be a source of germs. Remove plants from the living area. Avoid cleaning cat litter boxes or birdcages. [cancer.ca]
- Weight Loss
Anemia occurred independently of the degree of weight loss. The platelet counts decreased by a clinically insubstantial, although statistically significant, amount (281,000-250,000; P < .0005). [ncbi.nlm.nih.gov]
In our study, the patients with SVR had significant weight loss compared to those without SVR. The association between body weight, weight loss and SVR is controversial. [medsci.org]

Workup
Severe cases of leukopenia should be investigated and treated urgently. Mild drop in counts without any symptomatic evidence may not need any laboratory investigation and will spontaneously resolve on its own without any treatment [8].
A thorough history of fever, anemia, mouth ulcers and hepatosplenomeagly should be noted. History of intake of drugs should be checked, especially cytotoxic drugs. Any exposure to radiation or chemotherapy should be sought out. Laboratory investigations such as a complete blood profile, urine analysis, ANA, serum protein electrophoresis and vitamin and folate level and anti-neutrophil antibodies tests should be done. Other specific tests include bone marrow examination, bone scan for any metastasis, CT scan to detect any liver or spleen lesion, lymph node biopsy in case of Hodgkin disease.

Treatment
Leukopenic patients are more susceptible to endogenous and hospital acquired infections. Simple measures which are of paramount importance in treatment of severe cases are good hand washing practices and skin cleaning, especially around orifices. Aseptic techniques, good venous access, minimizing invasive procedures and intramuscular injections are important measures.
Attempts to locate the site of infection and identify the organisms involved should be made in all cases. Cultures of throat, urine, sputum and blood and X-ray chest are mandatory. A combination of broad spectrum antibiotics [9] should be given. Vitamins and steroids are also given to help increase the level of WBCs. Cytokines therapies are advised when cancer is the cause. Most patients with mild to moderate leukopenia do not require any treatment. Antibiotics suffice in case of infection. Autoimmune disorders require steroids to improve counts.
Prognosis
The prognosis of leukopenia depends upon the cause, duration of leukopenia, as well as age of the patient. Due to easy availability of broad spectrum antibiotics along with good supportive care, recovery even for severe cases is good. Morbidity is high in cases of long and severe infections which can be anything from skin infections to systemic infections and septicaemia.
Complications and fatality is high in cases of malignancy and AIDS. Fever due to decreased neutrophils in cancer can affect about 4-30% of individuals. Death occurs if septicaemia is not brought under control. Drug induced leukopenia also carries a high mortality rate , but with timely and vigorous antibiotic treatment outlook is better.
Etiology
The five types of leukocytes found in peripheral blood are neutrophils, eosinophils and basophils which are the granulocytes, the lymphocytes and the monocytes. The normal white blood count 4000-11,000 per cubic millimeter of blood. A count less than 3,500 cubic millimeter is regarded as leukopenia [3]. There are a number of causes which can lead to leukopenia such as:
- Certain infections like malaria, typhoid, kala azar, influenza, brucellosis and viral hepatitis
- Overwhelming bacterial infections especially in patients with poor resistance like miliary tuberculosis or sepsis [4]
- Drugs, chemicals and physical agents which induce aplasia of the bone marrow e.g. anti metabolites, ionising radiation.
- Certain hematological and other diseases such as pernicious anemia, aplastic anemia, liver cirrhosis, systemic lupus erythematosus, Gaucher disease
- Cachexia and debility
- Anaphylactoid shock
- Certain rare hereditary or familial disorders like cyclic neutropenia, primary splenic neutropenia, idiopathic benign neutropenia
- Vitamin and folate deficiencies
- Deficiency of zinc and copper
- Autoimmune disorders
Epidemiology
The incidence of leukopenia is quite common in patients with advanced stage HIV infection, occurring in 85-90% cases of clinical AIDS. The levels of neutrophils and lymphocytes are chiefly affected, neutrophils being less than 1000 per cubic millimeter of blood [5]. Age seems to influence the neutrophil count and elderly people have higher risk of leukopenia than younger individuals. Congenital forms of leukopenia more common in childhood.
Leukopenia tends to have a predilection for women more than men; this can be because of frequent usage of drugs by women. Leukopenia and neutropenia is also common in individuals treated with valproate and quetiapine. Leukopenia occurs frequently on patients receiving chemotherapy and anti tuberculosis treatment, though spontaneous recovery happens. Sometimes the therapy will have to be stopped if the counts fall too low.
Pathophysiology
A reduction in the counts of any of the 5 leukocytes implies leukopenia [6]. Monocytes, basophils and eosinophils already exist in scant numbers such that a reduction in these does not significantly cause a decrease in total white blood cell count or affect the body significantly. It is mainly a decrease in neutrophils and lymphocytes which are the major white blood cells which can cause leukopenia.
All leukocytes are produced from the precursors present in the bone marrow known as pluripotent hematopoetic stem cells. Due to a short lifespan of these cells, the bone marrow is constantly producing new white blood cells. In the bone marrow they are present in two stages- the proliferative stage and the mature stage. Sites of leukopenia can be limited to any of these stages-
The pathophysiology can be divided into two categories-
- Disorders of production or release of leukocytes from marrow- any damage or injury to bone marrow, bone marrow malignancies. Disorders in the pluripotent haemopoetic cells itself.
- Disorders of disposal or utilisation (spleen, tissues)
As a result of this, leukopenia can lead to severe infection which mainly affects skin, mucus membranes and genital areas.
Prevention
The most important way to prevent leukopenia is to boost the immune system and keep it strong. It is vital to immediately check and investigate any signs of illness and prevent the infection from progressing [10]. Certain lifestyle modifications can also help such as regular exercising especially if overweight as it can affect the functioning of the immune system.
Summary
Leukopenia is a clinical condition characterized by reduction in bone marrow production of white blood cells, especially the granulocytes, leaving the body inadequately protected against bacteria and other agents that might invade the body tissues. This condition predisposes the individual to many serious infections. Leukocytes help to fight off and protect the body from infectious or foreign agents. These cells are produced by the hematopoetic system and found all over the body including blood and lymphatic system. Technically, it implies a fall in neutrophils, monocytes and even lymphocytes. Yet, in clinical practice, it is synonymous with neutropenia [1].
Normally, the human body lives in symbiosis with many bacteria because many mucus membranes of the body are constantly exposed to the environment. Any decrease in the leukocytes is immediately followed by an attack of bacteria that are already present in/on the body. Within two days after the bone marrow stops producing white blood cells, ulcers appear in the mouth and colon or the individual develops some kind of respiratory infection. Without treatment death often ensues in less than a week after acute total leukopenia occurs. Any irradiation by gamma rays, or exposure to drugs and chemicals like benzene is likely to cause aplasia of the bone marrow which produces white blood cells. Many drugs, even certain antibiotics, can cause aplasia of the bone marrow causing leukopenia.
After moderate irradiation injury to the bone marrow, some stem cells may remain undestroyed and are capable of regenerating themselves provided sufficient time is available. A patient properly [2] treated with transfusion plus antibiotics and other drugs to ward off infections usually develops enough new bone marrow within several weeks for white blood cell concentrations to return to normal.
Patient Information
Leukopenia is a medical condition where the White blood cell levels reduce. The White blood cells are basically the soldiers of the body responsible for fighting away all infections and foreign agents. There are 5 types of white blood cells out of which neutrophils are the most abundant one and hence the terms leukopenia and neutropenia are often used interchangeably. They are responsible for protecting the body against all microorganisms. The level of leukocytes can fall due to many reasons ranging from malignancies, any disease of the bone marrow, HIV, any severe infections and autoimmune disorders. There can be many other causes of leukopenia.
Symptoms may vary, some patients may show no symptom other than mouth ulcers and fever indicating of an infection in the body. Other symptoms include tiredness, recurring infections, stomach pains. sore and swollen gums and other symptoms. It is important to consult your doctor who will need to do various tests such as blood tests and other specific tests to come to a diagnosis. Mild infections demand no treatment and are self resolving. In severe cases, antibiotics along with other therapies to build up white blood count in the body will be required. Steroids and cytokine therapies may be required in case of malignancies.
