The only way to know if your viral load is undetectable over the long term is to have regular viral load tests. You should have an undetectable viral load for at least six months before you can rely on undetectable viral load as an HIV prevention strategy.. When starting HIV treatment it usually takes three to six months before the viral load becomes undetectable. Most people will eventually have an undetectable viral load if they take their HIV treatment exactly as prescribed by their doctor and have a drug combination that is effective against their strain of HIV.. Once your viral load has become undetectable, it is important to regularly monitor the viral load to ensure that it remains undetectable. If your viral load becomes detectable again, there may be a risk of HIV transmission. An ongoing detectable viral load may also indicate that your HIV treatment is no longer working properly. If your viral load does become detectable, then you should discuss your options with your doctor. It is ...
The retrospective analysis included 21,400 people who were eligible for point-of-care viral load testing and who had been on ART for at least three months, up to June 2017. Eighty-five per cent received a viral load test during the study period and 89% of those tested had a viral load below 1000 copies/ml - almost matching the UNAIDS target of 90% of people on ART being virally suppressed.. Of those with a viral load above 1000 copies/ml, 83% received a follow-up test. Less than a third (29%) had a viral load below 1000 copies/ml on the follow-up test. Of those with a viral load above 1000 copies/ml on the follow-up test, 70% received a third viral load test.. Re-suppression was rare among those who received a follow-up test; only 15% had a viral load below 1000 copies/ml at follow-up. Eighty per cent of those with viral load above 1000 copies/ml were switched to second-line treatment. Switching rates and the rate of post-switch viral load testing were significantly higher at decentralised ...
The new test offers a broad dynamic range from high levels of virus in a patients blood to the "undetectable" low levels of viremia -- the goal of therapy.

HCV RNA viral load is an important predictor of sustained virological response and, recently, a significant correlation with liver fibrosis was described. We investigated on possible influence of clinical and viro-immunological variables on HCV viral load in HIV-HCV co-infected patients over a study time of three years (2009-2012). We retrospectively enrolled 98 adult patients with a diagnosis of chronic HIV infection in 2009, a diagnosis of chronic HCV infection with a detectable plasma HCV RNA in 2009 and 2012, HCV therapy-naïve or with failed and stopped antiviral treatment before June 2008. The following variables were recorded: age, gender, HCV genotype, IL28B rs12979860 CC genotype, HCV treatment status, advanced liver fibrosis diagnosis, antiretroviral therapy, CD4+ cell count, HCV viral load, HIV RNA (plasma HIV-1 RNA levels were measured from blood samples every three months at least). The correlation was established using linear regression analysis, analysis of variance and Fishers exact
To evaluate, in HIV-infected patients whose baseline CD4 count is 300 to 750 cells/mm3, whether an antiretroviral treatment regimen based upon clinical evaluation and CD4 counts plus HIV RNA viral load is more effective than a treatment regimen based upon clinical evaluation and CD4 counts without the use of HIV RNA viral load information. To assess relative utility of viral load testing in determining therapeutic choice by the surrogate marker of CD4 cell counts after 48 weeks of therapy.. It is hypothesized that among HIV-infected patients whose baseline CD4 count is in the range of 300 to 750 cells/mm3, those patients who incorporate initial and periodic viral RNA measurements in their therapeutic decisions will have higher CD4 counts after 48 weeks than patients whose therapeutic decisions do not incorporate initial and periodic viral RNA measurements. ...

This illustrated leaflet gives basic information on undetectable HIV viral load.. If your viral load result is undetectable, there is only a little HIV in the body. The aim of HIV treatment is to have an undetectable viral load: this means that your HIV is being kept under control.. If you have had an undetectable viral load for at least six months, and you continue to take your treatment as prescribed, there is no risk of passing HIV on during sex. ...

SEATTLE - People living with HIV who undergo HIV viral load testing at the point of health care delivery and receive their results immediately go on to achieve undetectable viral loads at higher rates than people whose testing is done at laboratories, researchers said here.. Results from the Simplifying HIV Treatment and Monitoring - or STREAM study - conducted in Durban, South Africa found that nearly 90 percent of study participants who received point-of-care viral load testing and same-day counseling had achieved viral suppression 12 months after testing, compared to 76 percent of participants who waited for the results of viral load testing conducted at laboratories - part of the prevailing standard of care - Dr. Paul Drain of the University of Washington said here.. Subjects whose samples were sent to labs were notified of their viral load results on average 28 days later, Drain said, compared to subjects who received their results within hours and had their results uploaded to the health ...
The present paper gives a brief description of study of decay of viral load in HCV infection during treatment of patients through various mathematical tools. In the study clinical data of few patients have been taken. The basic model of HIV infection adapted by Neumann et al has been taken in to account and explained to understand the decay or flow of viral load. For eight consecutive weeks data of viral load has been taken which is based on clinical data. Then, by using RStudio simulation (R-language) viral load is forecasted further for six more weeks. The forecasted viral load totally resembles with viral load through clinical data established by using Origin Lab. The sensitivity analysis of study of viral load of HCV during treatment for fourteen weeks shows specific pattern which will help in the treatment of Hepatitis C infected patients. In this study immunity of a human body is excluded.. Keywords: Mathematical model, Graphical presentation (MATLAB), Simulation (RStudio), Forecasting of ...

Researchers in Paris focused on two sets of patients--group 1 consisting of 413 people with a viral load always below 20 copies and group 2 including 25 people with at least two viral loads between 20 and 50 copies [1]. The investigators measured viral loads at least three times through the 1 year after inclusion in the study with the COBAS AmpliPrep TaqMan HIV-1 assay. During that time, 267 of 413 people in group 1 (65%) and 11 of 25 in group 2 (44%) had viral loads consistently below 20 copies, a nearly significant difference (P = 0.053 ...
Hepatitis c undetectable viral load - What is the difference between hepatitis C viral load and hepetitis c genotype? Numbers and type. Viral load refers to how many viral molecules can be detected in the blood. It gives an idea about how active the virus is and can be used to monitor response to therapy. Genotype refers to a test that can identify subtypes of hep c. Certain genotypes are more likely to respond to a given therapy, so this information can be useful in deciding in what treatment, if any, would be best.

Due to the limited number and mechanism of action of current agents, any changes in a regimen will lead to further constraints on therapy in the future of the patient in question. Antiretroviral changes should be made cautiously. Recommendations regarding changing antiretroviral therapy include the following:. A. Therapy should not be changed prematurely. Virologic and immunologic trends should be established before medication changes are planned. See below.. B. If viral load measurements are being used to change therapy, repeat the viral load measurements prior to most, if not all, significant changes. The exception to this is the already observed trend of increasing viral load and decreasing CD4-lymphocytes with or without clinical deterioration.. C. Consideration of antiretroviral therapy change in the setting of possible virologic failure should be done in the following situations:. 1) Viral load becomes detectable and continues to rise in someone who had previously had an undetectable viral ...
Its complicated but here is what almost came about: people living with HIV in Ontario would have had their viral load test results, with their names attached, sent from the provincial testing labs to their local public health unit.. For what? Public Health Ontario proposed leaving it up to the individual local health units to decide. The move followed a legal opinion obtained by Public Health Ontario that as HIV is a reportable disease (thats not new), the required reporting to local health units includes viral load test results (that certainly IS new). The new rules, formed without community consultation, were slated to start as early as September 2017. Thanks to community mobilization which triggered the involvement of CATIE, the Ontario HIV Treatment Network (OHTN), the Ministry of Health and Long Term Cares AIDS Bureau and AIDS Action Now, the changes wont happen - for now.. Its not hard to see why community members were shocked, if not outraged. by the proposed changes. They challenge ...
A viral load test measures how much human immunodeficiency virus (HIV) is in the blood. Viral load is first measured when you are diagnosed with HIV infection.
Viral loads can fluctuate over time depending on patients access and response to HIV treatment, their medication adherence behavior, and care status.
Simon Collins, HIV i-Base. On 7 December 2012, the US FDA approved changes to the rilpivirine (Edurant) package insert that included restricting the indication to treatment-naïve adult patients with HIV viral load less than 100,000 copies/mL.. Previously, the FDA had only highlighted the poorer responses in patients with baseline viral load ,100,000 copies/mL. This brings the US indication in line with the label indication originally granted by the EU. On 25 January, a similar change occured for the Fixed Dose Combination of Eviplera that contains rilpivirine/tenofovir/FTC.. Of note, the FDA review included a different summary of data relating to the risk of resistance based on baseline viral load and CD4 count, that appears to be different to the analysis of the 96 week pooled phase 3 data in the EU Summary of Product Characteristics, see Table 1 and 2.. This showed that in people failing virologically, there were disproportionately higher rates of resistance when stratified by both baseline ...
The UNC team analyzed data on 1481 HIV-positive women in WIHS from 2006 through 2009. WIHS enrolls HIV-positive and high-risk negative women in the Bronx, Brooklyn, Chicago, Los Angeles, San Francisco, and Washington, DC. The researchers grouped women according to self-reported health insurance--no insurance, Medicaid, Medicare or other public insurance, and private insurance. They also ranked women by annual income--below $6000, $6001 to $12,000, $12,001 to $18,000, or above $18,000. Defining an unsuppressed viral load as HIV RNA above 200 copies, the investigators used Cox proportional hazards models to estimate time from 2006 to 2009 with an unsuppressed viral load by insurance type and stratified by ADAP access (yes or no). WIHS records viral load every 6 months ...
Viral load means exactly what it sounds like -- its an estimate of how much HIV is circulating in your blood. Generally speaking, your viral load is not considered as critical as your CD4 count in determining the health of your immune system. However, once you begin HIV treatment, it is a good measure of how well your HIV medications are working.. A viral load test measures the amount of HIV in a small amount (milliliter, or mL) of your blood. The most sensitive viral load tests currently used in clinics can detect as few as 20 copies of HIV per milliliter of blood. When your viral load test indicates that you have fewer than 20 copies/mL of HIV, your health care provider will tell you that your viral load is "below the limit of detection," or "undetectable.". This does not mean you no longer have HIV in your body. Though it is not technically impossible for someone who has an "undetectable" viral load to transmit HIV, studies show that there is virtually no risk of HIV transmission when a ...

Background The prognostic value of CD4 counts and RNA viral load for identifying treatment need in HIV-infected individuals depends on (a) variation within and among individuals, and (b) relative risks of clinical progression per unit CD4 or RNA difference. Methodology/Principal Findings We reviewed these measurements across (a) 30 studies, and (b) 16 cohorts of untreated seropositive adults. Median within-population interquartile ranges were 74,000 copies/mL for RNA with no significant change during the course of infection; and 330 cells/µL for CD4, with a slight proportional increase over infection. Applying measurement and physiological fluctuations observed on chronically infected patients, we estimate that 45% of population-level variation in RNA, and 25% of variation in CD4, were due to within-patient fluctuations. Comparing a patient with RNA at upper 75th centile with a patient at median RNA, 5-year relative risks were 1.4 (95% CI 1.2-1.7) for AIDS and 1.5 (1.3-1.9) for death, without change
VL was more likely to be detectable if participants had OIs in the prior three months compared to when they did not (OR=4.0 (95% CI=1.9-8.6)). The CD4+ T cell counts declined 24.1 cells/µL per three months in intervals where the participants had OIs compared to an increase of 21.3 cells/µL per three months in intervals where they did not have OIs (adjusted difference in the rate of CD4+ T cell count change of 61.7 cells/µL per three months (95% CI=13.7-109.7), P value=0.012). The rate of CD4+ T cell count increase was 25.6 cells/µL per three months (95% CI=11.6-39.6) higher for females compared to males (p value ...

When the amount of HIV in the blood is too low to be detected with a viral load (HIV RNA) test. Antiretroviral (ARV) drugs may reduce a persons viral load to an undetectable level; however, that does not mean the person is cured. Some HIV, in the form of latent HIV reservoirs, remain inside cells and in body tissues.
Results 19 [45%] patients achieved SVR versus 23 [70%] who did not. No statistically-significant differences were observed for the variables sex [68% male vs. 70%]; fibrosis stage [6% F2 vs. 0%, 27% F3 vs. 17%, 67% F4 vs. 83%]; HIV-HCV coinfection [26% vs. 13%]; baseline haemoglobin [150 ± 16 mg/dl vs. 147 ± 16]; AST [61 ± 47 mU/ml vs. 70 ± 38] and ALT [78 ± 61 mU/ml vs. 72 ± 42] levels. In contrast, differences were founded in age [52 ± 7 years vs. 57 ± 9] and in viral load reduction after the lead-in [24% ,1 log vs. 64%]. The Chi-squared test showed a statistically-significant relationship between SVR and undetectable viral load at weeks eight and twelve, as well as at the end of treatment. Logistic regression showed that viral load at week eight (OR: 5.03 [95% CI:1.25-20.19]) was the only independent predictor of SVR. This association remained significant after controlling independently for age. ...

The higher your viral load the more likely you are to pass on HIV to a sexual partner. High viral loads are more likely in someone recently infected with HIV (during seroconversion) or in someone with advanced HIV disease not on antiretroviral therapy (HAART). HAART reduces viral loads in blood to less than 50 copies per ml. But studies have shown that even when the viral load is undetectable in blood it can still be detected in semen and infect a partner. Levels of HIV in semen are also increased if someone has a sexually transmitted infection. There have been many case reports of HIV infections occurring this way. So it is important to continue to use a condom even if your viral load is undetectable.. ...

More than half of the participants had 3 or more comorbidities and their HIV pill purchase Pimaricin burden was high (more than 2 pills daily). After 12 months, 65 participants achieved undetectable viral load levels, whereas 15 experienced virologic failure (2 consecutive viral loads 50 copies/mL) and the remaining 20 had persistent VLLV. In the virologic failure group, there was a predominance of white males (66%) with a significant number of comorbidities and pill burden. Univariate logistic regression suggested that there was a difference between the failure versus nonfailure groups in terms of race, ethnicity, and alcohol use. Multivariate regression with virological failure as the outcome ...
Viral load tests are blood tests that measure HCV ribonucleic acid (RNA, or genetic material) in the blood. The presence of viral RNA indicates that the virus is actively replicating (reproducing and infecting new cells). A viral load test is usually first done after a person has tested positive for exposure to HCV based on an antibody test. A blood sample is taken and the amount of HCV RNA in a milliliter of blood is measured. Viral load tests confirm whether an individual is actively infected with HCV. Viral load test results are reported in terms of International Units per milliliter (IU/mL).. HCV Genotype, Quasispecies & Subtype ...
Objective: The possible role of Human Herpes Virus-6 in cardiac disorders in childhood was explored in a retrospective study on archival specimens of explanted hearts.. Methods: 16 children (median age at transplantation 11.0 years) with idiopathic dilated cardiomyopathy (DCM) and 19 children (median age at transplantation 1.0 year) with congenital heart disease (CHD), previously found negative for other cardiotropic viruses such as Enteroviruses, Adenovirus, Parvovirus B19, CMV, and EBV, were tested for HHV-6 by quantitative Real-Time PCR and by genotyping. In addition, HHV-7/8 infection was investigated by qualitative PCR.. Results: HHV-6 B variant was detected in 11 out of 35 samples (31.4%) with a mean viral load of 3.15 x102 copies/µg of cellular DNA. When assessed by heart disorder, the prevalence was different in the two groups (i.e. 43.7% in DCM and 21% in CHD) while the mean viral loads were similar. In a logistic multivariate analysis HHV-6 was independently associated with DCM taking ...
Initiating combination anti-HIV therapy (ART) can greatly reduce the amount of HIV in the blood (viral load). Over time, as the viral load continues to fall, in the majority of people it reaches a very low level that cannot be accurately assessed using routine laboratory tests. Such low viral load levels are commonly called

Additional experiments revealed that the HIV-specific CD4 T cell responses showed activity associated with cell-killing and could even destroy HIV-infected macrophages - an unusual function for CD4 T cells, which have traditionally been seen as helper cells. In addition, the researchers determined that the presence of a specific cell-death protein called granzyme A prominently distinguished HIV-specific CD4 cells of participants maintaining a lower "viral set point" from those less able to control viral levels. To validate these findings, the researchers examined a larger group of HIV-infected individuals and found that those with higher levels of granzyme A in their HIV-specific CD4 T cell response immediately after infection progressed more slowly to AIDS and did not require antiretroviral therapy as quickly as did those with lower levels of the protein. "The key baseline difference between these two groups has to do with the quality, not the quantity, of the HIV-specific CD4 T cell response," ...

Correlation of High Interleukin 17A and Interleukin 6 Levels with High Virus Load Among Subtype C HIV-infected, Antiretroviral Therapy-naive Zimbabwean Patients: A Cross-sectional Study
Pandemic (H1N1) 2009 virus causes severe illness, including pneumonia, which leads to hospitalization and even death. To characterize the kinetic changes in viral load and identify factors of influence, we analyzed variables that could potentially influence the viral shedding time in a hospital-based cohort of 1,052 patients. Viral load was inversely correlated with number of days after the onset of fever and was maintained at a high level over the first 3 days. Patients with pneumonia had higher viral loads than those with bronchitis or upper respiratory tract infection. Median viral shedding time after the onset of symptoms was 9 days. Patients <13 years of age had a longer median viral shedding time than those >13 years of age (11 days vs. 7 days). These results suggest that younger children may require a longer isolation period and that patients with pneumonia may require treatment that is more aggressive than standard therapy for pandemic (H1N1) 2009 virus.

In general, your viral load is the most important factor in determining whether your medications are working. Other important factors are your CD4 (T-cell) count, your recent clinical history, and findings from a physical examination by your doctor. Your viral load should be tested again 2-4 weeks after you start treatment. If your drugs are working, your viral load should be decreasing, and it should continue to decrease as you continue to take your medications.. Throughout HIV treatment, your viral load should be tested every 3-4 months to make sure your drugs are still working. If your viral load is not detectable within 4-6 months after starting treatment, you should talk to your doctor about possibly changing your medications.. How fast or how much your viral load decreases may depend on other factors, not only on the drugs you are taking. These factors can include your baseline viral load and CD4 (T-cell) count (before starting therapy), whether you have used Antiretroviral drugs before, ...
There are inefficiencies in current approaches to monitoring patients on antiretroviral therapy in sub-Saharan Africa. Patients typically attend clinics every 1 to 3 months for clinical assessment. The clinic costs are comparable with the costs of the drugs themselves and CD4 counts are measured every 6 months, but patients are rarely switched to second-line therapies. To ensure sustainability of treatment programmes, a transition to more cost-effective delivery of antiretroviral therapy is needed. In contrast to the CD4 count, measurement of the level of HIV RNA in plasma (the viral load) provides a direct measure of the current treatment effect. Viral-load-informed differentiated care is a means of tailoring care so that those with suppressed viral load visit the clinic less frequently and attention is focussed on those with unsuppressed viral load to promote adherence and timely switching to a second-line regimen. The most feasible approach to measuring viral load in many countries is to ...
