If you have HIV, your doctor will regularly request a battery of blood tests to better monitor and assess:. Central to these examinations is another test called the complete blood count CBC. By doing so, the CBC can identify and ideally prevent the development of treatment-related side effects, as well as to detect any disorders that may be related to HIV infection. The test itself measures several components or features of your blood, including the white blood cells, the red blood cells, and platelets. White blood cells, also known as leukocytes, are a subset of cells produced in the blood marrow, whose primary aim it is to fight infection.
There is still controversy about whether aggressive early treatment of HIV infection with anti-HIV medications also called antiretroviral medications will slow the long term progression of disease. This page was last reviewed in November How quickly would you have spotted these 3 cases? Historically, HIV testing had been considered primarily for individuals with certain high-risk factors that increase their likelihood of infection TABLE 3. P -values below 0.

The virus is spread by:. After someone is infected with HIV, blood tests can detect antibodies to the virus, even if they never had any symptoms of their infection. This is called HIV seroconversion converting from HIV negative to HIV positive by blood testing , and usually occurs within 3 months of exposure, but on rare occasions can by delayed up to a year after infection.
Following the initial infection, there may be no further evidence of illness for the next 10 years. This stage is called asymptomatic HIV infection. However, the vast majority of patients do ultimately progress to AIDS. To date there are a small number of people who have tested positive for HIV, but later no longer test positive and have no signs of disease.
Although this is relatively rare, it provides evidence that the human body may be capable of removing the disease. These people are being carefully watched and studied. HIV has spread throughout the world. Higher numbers of people with the disease are found in large metropolitan centers, inner cities, and among certain populations with high-risk behaviors. Acute HIV infection can appear like infectious mononucleosis , flu , or other viral illnesses.
If symptoms occur, they are usually seen 1 - 4 weeks after becoming infected. Lower-than-normal CD4 white blood cell count may be a sign of a suppressed immune system. The CD4 count usually improves 1 - 2 months after acute infection. People with HIV infection need to be educated about the disease and its treatment so they can be active partners in making decisions with their health care provider. There is still controversy about whether aggressive early treatment of HIV infection with anti-HIV medications also called antiretroviral medications will slow the long term progression of disease.
You should discuss this option with your health care provider. You can often reduce the stress of illness by joining a support group where members share common experiences and problems. See AIDS - support group. However, appropriate treatment can dramatically improve the length and quality of life for persons infected with HIV, and can delay the onset of AIDS.
The treatments for conditions that occur with early symptomatic HIV disease vary in effectiveness. Some infections and diseases are easier than others to treat with medications. Call for an appointment with your health care provider if you have had a possible or actual exposure to AIDS or HIV infection, or if you are at risk and have had symptoms like those of acute HIV infection.
Safer sex behaviors may reduce the risk of getting the infection. There is still a risk of getting infected with HIV, even if you practice "safe sex," because condoms can break. Abstinence is the only sure way to prevent sexual transmission of the HIV virus. People who are at risk for HIV infection should have regular testing to ensure early diagnosis and prompt treatment.

Any of the following symptoms can occur: Decreased appetite Fatigue Fever Headache Malaise Muscle stiffness or aching Rash Sore throat Swollen lymph glands Ulcers of the mouth and esophagus These symptoms can last from a few days to 4 weeks, and then subside.
White blood cell differential may show abnormalities. Treatment People with HIV infection need to be educated about the disease and its treatment so they can be active partners in making decisions with their health care provider.
Follow these healthy practices in the early stages of HIV infection: Avoid exposure to people with infectious illnesses. Avoid settings and situations that could lead to depression. Maintain positive social contacts, hobbies, interests, and pets.
Eat a nutritious diet with enough calories. Get enough exercise, but don't wear yourself out. Keep stress to a minimum. Practice safer sex. The disease is highly transmissible, especially in the first months after infection.

General guidelines: Do not have unprotected sexual intercourse with numerous partners or anyone who has multiple partners, uses IV drugs, or that has or may be infected with AIDS. Avoid injection drug use. If you do use such drugs, do not share needles or syringes. People with AIDS or who have had positive HIV antibody tests can pass the disease on to others and should not donate blood, plasma, body organs, or sperm. Do not exchange body fluids during sexual activity. Images Kaposi's sarcoma - lesion on the foot.

Hiv and decreased wbc. What are white blood cells or leucocytes?
Kevin Pho, MD. There are many reasons for a low WBC count. HIV is one of them, although you may want to look at more common causes first. Any viral infection can decrease the WBC count transiently. As the virus passes, the WBC will normalize again. Persistently low WBC counts can also be due to various forms of lymphoma.
If this is the case, a bone marrow biopsy can be considered. Various immunosuppressive disorders, including HIV, can be considered.
Because of this, I would advise testing. Followup with your personal physician is essential. This answer is not intended as and does not substitute for medical advice - the information presented is for patient education only.
Please see your personal physician for further evaluation of your individual case. Kevin, M. I have a low white blood count when I am very sick and I can asure you I do not have aids.
Not even anything close to that. I would just practice safe sex and get checked for it at least once a yr. So stop freaking out,I'm sure its because of your cold. Good luck. I'm going to say it's. You have a cough and cold and a diagnosis of bronchitis. HIV takes in almost all cases only few months to convert, at most six months.

Think a loved one may be experiencing hearing loss? Here are five warning signs to watch for. The Best Time for Your Health. When this condition called cytopenia or leukopenia occurs, the body is less able to fight infection.
Among the most important white blood cells are CD4 "helper" T-cells and CD8 "killer" T-cells, which respectively trigger an adaptive immune response and aim to neutralize the virus. Additionally, there are cells called macrophages, dendritic cells, and Langerhans cells which comprise part of the body's innate built-in immune response.
These cells function as the first-line defense whenever an infection agent tries to enter the body. Red blood cells, also known as erythrocytes, are responsible for carrying oxygen from the lungs to the various cells and tissues of the body. The RBC value is then used to evaluate the hematocrit percentage of blood volume taken up by red blood cells , while an additional assay measures the protein in red blood cells called hemoglobin that are responsible for carrying the oxygen molecules.
Very low readings of RBC values can indicate anemia , a condition wherein cells and tissues are not provided ample supplies of oxygen. When this happens, a person will often feel fatigued or exhausted, pretty much all the time, and may look visibly pale or washed out. If anemia is diagnosed while a person is on zidovudine, an iron supplement may be prescribed if the anemia is considered mild.
In more severe or persistent cases, the drug may need to be substituted with another appropriate agent. While zidovudine is less commonly used in first-line HIV therapy, it remains an important drug option for some, particularly during pregnancy.
Severe cases of anemia are sometimes treated with erythropoietin, an antibiotic drug of which can stimulate the synthesis of red blood cells, or may require an intravenous blood transfusion to effectively top up these cells.
Platelets, also called thrombocytes, are colorless cells that are involved in the blood clotting process. Low platelets values can lead to easy bleeding or bruising in the affected individual.
Severe cases can even result in potentially life-threatening internal bleeding. The condition, known as thrombocytopenia, is associated with chronic HIV infection, primarily in people with advanced disease who are not yet on treatment.
The initiation of HIV therapy can generally resolve the condition by suppressing the inflammatory agents associated with infection, which is known to deplete platelet numbers.

Laboratory Tests and HIV: Entire Lession - HIV
HIV-induced changes in cytokine responses to bacteria may influence susceptibility to bacterial infections and the consequent inflammatory response. We examined the impact of HIV on whole blood responsiveness to bacterial stimulation in asymptomatic subjects and patients with bacterial bloodstream infection BSI. Whole blood was stimulated ex vivo with two bacterial Toll-like receptor agonists lipopolysaccharide and lipoteichoic acid and two pathogens Streptococcus pneumoniae and non-typhoidal Salmonella , which are relevant in HIV-positive patients.
These results suggest a complex effect of HIV on leukocyte responses to bacteria. However, in patients with sepsis, leukocyte responses were equally blunted in patients with and without HIV infection. HIV patients have an increased risk of developing bacterial bloodstream infections BSIs and sepsis, which are associated with higher mortality [ 1 — 4 ]. Although the immunological mechanisms behind enhanced susceptibility, morbidity and mortality due to bacterial infections in HIV patients are incompletely understood, previous studies suggest a role for inadequate release of soluble mediators such as cytokines [ 5 ].
Pro-inflammatory cytokine release is an essential element of the host response during bacterial infection, which is important for protective immunity but also causes collateral damage due to exaggerated inflammation [ 6 ]. Sepsis is also associated with immune suppression, which involves a reduced ability of leukocytes to respond to re-stimulation with bacterial agonists [ 7 , 8 ]. In contrast, previous investigations suggested that HIV infection results in priming of leukocytes to stimulation with bacterial agonists.
Knowledge on the impact of HIV infection on the responsiveness of whole blood leukocytes to bacterial stimuli is limited, especially in the HIV endemic setting of sub-Saharan Africa. This information is relevant to understand host defences against bacteria in HIV patients and to obtain insight into the effect of HIV infection on hyper-inflammation and immune suppression during sepsis.
Therefore, we examined 1 the whole blood leukocyte response in asymptomatic patients with HIV compared to healthy controls and 2 whether HIV co-infection influences sepsis-induced suppression of leukocyte responses to a secondary stimulus. The cohort reported here was featured in part in previous studies on the impact of HIV infection on presentation and outcome of febrile illness, activation of the complement system and neutrophil extracellular traps [ 4 , 14 , 15 ].
Patients were included in the present analysis as soon as the blood culture became positive; at that moment, a second blood sample was drawn for whole blood stimulation as described below. Afebrile, asymptomatic controls, with or without HIV infection, were recruited in the vicinity of the hospital and the HIV outpatient clinic. Written informed consent was obtained from all participants or their guardians. Coagulase-negative staphylococci and Bacillus spp.
Streptococcus viridians were regarded as contaminants as well, unless the patient had clinical signs of endocarditis or meningitis. As part of a clinical trial requirement, the microbiology laboratory at the Albert Schweitzer Hospital successfully participates in regular external quality assurance programmes addressing species identification.
Glomerular filtration rates were estimated by the modification of diet in renal disease MDRD formula [ 16 ]. Stimulations in BSI patients and controls were done on one occasion. Asymptomatic subjects were sampled on inclusion into the study. To establish the optimal dose of heat-killed bacteria, LPS and LTA, to induce a robust cytokine response, we performed whole blood stimulations with serial dilutions of stimuli, using blood from healthy volunteers.
Each cytokine assay was done for all samples in one run on the same day using the same batch of reagents, thereby eliminating inter-assay variability.
Categorical variables are presented as percentages and continuous variables as medians with their interquartile range in the table and as box-and-whisker plots in the figures.
We used Fisher's exact tests for comparisons of categorical variables, Mann—Whitney U tests or Kruskall—Wallis tests to assess differences for non-normally distributed continuous variables, and unpaired t -tests or one-way ANOVA tests for normally distributed variables. Cytokine release in response to a stimulus was determined by calculating the difference in cytokine levels between the stimulated and medium control samples.
Outliers were determined using a Grubbs test. Samples with outliers in the unstimulated control were excluded from our analyses. An additional sensitivity analysis was performed in some cases to correct for differences in leukocyte count by dividing cytokine read-outs by the number of leukocytes. This was an exploratory study, so a formal sample size calculation could not be performed.
No mathematical correction was made for multiple comparisons. Table 1 presents the baseline characteristics of the study population. In addition, we obtained blood cultures from patients, 33 of which revealed a bacterial pathogen, including 14 patients with HIV infection. Data are presented as medians interquartile ranges , except for sex, renal failure, liver injury and antibiotic treatment; p -values below 0.
The causative pathogens are depicted in Table 2. There were no differences in pathogens according to HIV status, except for infection with S. Two asymptomatic HIV patients had to be excluded from analysis due to outliers in the unstimulated control samples. Cytokine releases from unstimulated whole blood medium control samples are depicted in Figure 1.
Spontaneous cytokine release by whole blood samples from BSI patients and asymptomatic subjects with or without HIV infection.
Whole blood was kept in RPMI medium for 24 hours. Data are depicted as box-and-whisker plots depicting the smallest observation, lower quartile, median, upper quartile and largest observation.
Significant differences between HIV-negative asymptomatic controls and asymptomatic HIV patients or sepsis cases are shown, as well as differences within groups asymptomatic or sepsis according to HIV status.
To examine whether this finding was related to lower leukocyte counts in asymptomatic HIV patients, a sensitivity analysis was performed in which results were corrected for leukocyte counts.
Whole blood was stimulated for 24 hours. The capacity of leukocytes to respond to bacterial agonists is a strong denominator of both the early protective immune response and the late, potentially damaging inflammatory reaction.
In addition, the reduced ability of leukocytes to react to bacterial agonists during established severe infection has been implicated as an important feature of immune suppression in patients with sepsis [ 7 ].
We hypothesized that HIV infection might influence the cytokine production capacity of blood leukocytes and studied this in asymptomatic subjects and patients with BSI. HIV infection had no influence on the diminished cytokine production capacity of blood leukocytes from BSI patients. Our findings extend the relevance of these findings to a whole blood stimulation model and a wider range of bacterial agonists.
Several mechanisms could be involved in reduced NK cell responsiveness in HIV patients, including the expansion of an unresponsive subset of NK cells and shedding of MHC class I chain-related molecules, which provide negative feedback to NK cells [ 5 ]. We observed no significant differences in whole blood leukocyte responses between asymptomatic patients with and without cART. A possible explanation for the absence of improvement on cART is the presence of more advanced disease in patients on cART, as illustrated by their lower CD4 counts Table 1.
However, we did observe consistent priming of pro-inflammatory cytokine release after stimulation with NTS in asymptomatic HIV patients without cART as compared to healthy controls. In line with this finding, a previous study found that HIV infection was associated with enhanced cytokine release from alveolar macrophages in response to NTS [ 22 ]. The enhanced susceptibility of HIV patients to invasive NTS suggests that enhanced pro-inflammatory cytokine release upon NTS exposure is not protective, but may contribute to more extensive tissue damage.
In patients with BSI, HIV co-infection had no impact on the capacity of blood leukocytes to release cytokines, regardless of the cytokine read-out or stimulus applied.
In line with this, we observed a predominantly common genomic response of whole blood leukocytes in Dutch ICU patients with or without sepsis [ 24 ]. These results suggest a predominantly common host response in sepsis patients with or without HIV co-infection.
Our study was limited by the relatively small number of patients with BSI, so we grouped patients with different pathogens and sites of infection. Possibly as a consequence, variance in leukocyte responses within groups was relatively large.
Differences in antibiotic treatment regimens was another potential source of variance. In order to avoid a type I error, we did not correct for multiple comparisons. However, by testing different bacterial stimuli and different read-outs, we were able to observe consistency in leukocyte responses in different patient groups. To the best of our knowledge, this is the first study to examine the impact of HIV on leukocyte responsiveness in patients with BSI.
