Management of Virologic Treatment Failure. The approach to management and subsequent treatment of virologic treatment failure will differ depending on the etiology of the problem. While the causes of virologic treatment failure may be multifactorial, nonadherence plays a role in most cases. Assessment of a child with suspicion of virologic treatment failure should include evaluation of adherence to therapy and medication intolerance, confirmation that prescribed dosing is correct for all medications in the regimen, consideration of pharmacokinetic (PK) explanations of low drug levels or elevated and potentially toxic levels, and evaluation of suspected drug resistance (see Antiretroviral Drug-Resistance Testing in the Guidelines for the Use of Antiretroviral Agents in HIV-1-Infected Adults and Adolescents). The main barrier to long-term maintenance of sustained virologic suppression in adults and children is incomplete adherence to medication regimens, with subsequent emergence of viral ...

CONTEXT: Presence of low-frequency, or minority, human immunodeficiency virus type 1 (HIV-1) drug resistance mutations may adversely affect response to antiretroviral treatment (ART), but evidence regarding the effects of such mutations on the effectiveness of first-line ART is conflicting.. OBJECTIVE: To evaluate the association of preexisting drug-resistant HIV-1 minority variants with risk of first-line nonnucleoside reverse transcriptase inhibitor (NNRTI)-based antiretroviral virologic failure.. DATA SOURCES: Systematic review of published and unpublished studies in PubMed (1966 through December 2010), EMBASE (1974 through December 2010), conference abstracts, and article references. Authors of all studies were contacted for detailed laboratory, ART, and adherence data.. STUDY SELECTION AND DATA ABSTRACTION: Studies involving ART-naive participants initiating NNRTI-based regimens were included. Participants were included if all drugs in their ART regimen were fully active by standard HIV ...
Virologic failure occurs in a large proportion of individuals receiving treatment with combination antiretroviral therapy. Studies suggest that treatment interruption prior to initiation of a multiple-drug rescue regimen may improve virologic response in individuals who have failed several prior antiretroviral regimens. Other studies suggest there is a virologic benefit derived from using genotypic or phenotypic resistance testing in selecting salvage therapy regimens for patients failing antiretroviral therapy. This study tests the hypothesis that salvage regimens selected on the basis of HIV-1 resistance genotype, phenotype [AS PER AMENDMENT 02/19/02: virtual phenotype], and treatment history will be more effective if there is a period of treatment interruption before initiating that regimen.. Patients continue their antiretroviral therapy until randomization. Based on the results of the pre-entry genotype and phenotype [AS PER AMENDMENT 02/19/02: virtual phenotype] tests and treatment ...

1. Torres et al performed an RCT in 3 Spanish hospitals over 8 years. 120 patients with severe CAP (CRP , 150mg/l) were given intravenous bolus of 0.5 mg/kg per 12 hours of methylprednisolone or placebo for 5 days, started within 36 hours of hospital admission.Treatment failure was the primary outcome.. (Early treatment failure was development of shock, new need for mechanical ventilation , or death within 72 hours. Late treatment failure defined as worse CXR, persistence of severe respiratory failure, or any early treatment failure criteria between 72 hours and 120 hours.). There was less treatment failure in the steroid group (13 v 31%). Looking more closely it was the late treatment failure that was more affected, particularly the occurrence of septic shock. No statistically significant difference in hyperglycaemia.. Only 120 patients in 8 years raises concerns about recruitment and consequently external validity. Also there was no mortality difference between the groups - although the ...
Sputum samples from ten individuals were positive for acid-fast bacilli. Three of these individuals were HIV-positive, and one of these people was newly diagnosed with HIV thanks to the community health campaign.. Nine of the TB diagnoses were new; the other case had previously been detected at a local health centre. Six of the new cases had microscopy results suggesting their TB was highly contagious. Overall, 0.31% of people were newly diagnosed with TB. The number of people needed to screen using symptoms and microscopy to identify a single new case was 3024. The number of people with prolonged cough who required screening with microscopy to identity a new case was 320, the figure falling to 80 per case for HIV-positive people with chronic cough.. All nine people with newly detected TB were linked to care and initiated TB therapy. This treatment was completed by six people. One individual experienced treatment failure and initiated a second-line regimen; one individual was lost to follow-up; ...
Objectives: Better understanding of the dynamics of HIV reservoirs under ART is a critical step to achieve a functional HIV cure. Our objective was to assess the genetic diversity of archived HIV-1 DNA over 48 weeks in blood cells of individuals starting treatment with a dolutegravir-based regimen. Methods: Eighty blood samples were prospectively and longitudinally collected from 20 individuals (NCT02557997) including: acutely (n = 5) and chronically (n = 5) infected treatment-naive individuals, as well as treatment-experienced individuals who switched to a dolutegravir-based regimen and were either virologically suppressed (n = 5) or had experienced treatment failure (n = 5 ...

Southern Africa has the highest prevalence of HIV worldwide, and South Africa has the highest number of HIV infected people. South Africa and other resource-limited countries provide antiretroviral therapy (ART) for people with HIV, with limited, standardized regimens for first line and second line. Patients who fail first line treatment are put on second line regimens, yet options for third line are very limited. The first study looks at predictors of first line treatment failure in South Africa and develops a predictive model that can estimate absolute risk of treatment failure over 5 years on ART, given a baseline profile of clinical and demographic factors. The model was developed with accelerated failure time models, using predictors that maximized discrimination between patients. The model can be used to identify patients who need adherence interventions, and to estimate how changes in baseline parameters in the population influence long-term need for second line ART. The second study ...
Treatment failure is a serious problem facing some national tuberculosis [TB] control programmes. Irregularity of treatment is a factor that can lead to treatment failure. A case-control study was carried out in TB centres in Egypt during April 2001-December 2002 aimed at investigating the predictors of treatment failure. We interviewed 119 people with treatment failure and an equal number of cured cases [controls] and their families regarding sociodemographic characteristics, information about TB, information about drugs, treatment compliance, family support and patient-family interaction. Significant risk factors for treatment failure were non-compliance to treatment, deficient health education to the patient, poor patient knowledge regarding the disease and diabetes mellitus as co-morbid ...
Our study indicates that 7% of patients with type 1 autoimmune hepatitis deteriorate during corticosteroid therapy and that treatment failure is associated with onset at an early age, acute presentation, hyperbilirubinemia, HLA DRB1*03, and a MELD score of at last 12 points. We could not ascribe the treatment failure to transition of the autoimmune hepatitis to another condition, and only 1 patient developed fatty liver disease, in whom treatment failure might have related to a superimposed or concurrent disease. Treatment failure was associated with a poor prognosis despite high-dose corticosteroid treatment, 7 patients (50%) either died of liver-related causes or required transplantation, and only 2 patients (14%) achieved remission.. Previous studies have indicated the importance of using disease severity, shown by histological pattern and laboratory features, to identify patients who have a poor prognosis if they are untreated.56 These findings, however, have not reliably identified those ...
Background: Timely detection of treatment failure with subsequent switch to second-line regimen reduces mortality among HIV infected people on antiretroviral therapy (ART). This paper aims to investigate the detection of immunological treatment failure and switch rate to second line regimen in Ethiopia. Methods: A retrospective cohort study was conducted among HIV infected patients (age > 15 years) who initiated ART between 2007 and 2009. The required data were collected from patient registers and formats. Data were entered and validated using EpiData software and then exported to SPSS version 20.0 for analysis. Odds ratio with 95 % CI was used to assess whether immunological treatment failure was associated with experiencing unfavorable treatment outcomes (death or lost to follow up). Results: Records of 293 patients were reviewed with a total of 1545 Person-Years of Observation (PYO). The median baseline CD4 count was 115 cells/mm3 (IQR: 64-176). A total of 46 (15.7 %) patients experienced ...

article{a788131c-c8d3-451e-9c12-43ec2f617e36, abstract = {,p,Background: Early identification of virological failure (VF) limits occurrence and spread of drug-resistant viruses in patients receiving antiretroviral treatment (ART). Viral load (VL) monitoring is therefore recommended, but capacities to comply with this are insufficient in many low-income countries. Clinical algorithms might identify persons at higher likelihood of VF to allocate VL resources. Objectives: We aimed to construct a VF algorithm (the Viral Load Testing Criteria; VLTC) and compare its performance to the 2013 WHO treatment failure criteria. Methods: Subjects with VL results available 1 year after ART start (n = 494) were identified from a cohort of ART-naïve adults (n = 812), prospectively recruited and followed 2011-2015 at Ethiopian health centres. VF was defined as VL≥1000 copies/mL. Variables recorded at the time of sampling, with potential association with VF, were used to construct the algorithm based on ...

Failure is a part of our life except for the lucky ones but im pretty sure that no one ever did not experience such. Experiencing it was a painful thing yet in the end when everything is already ok we realize that everything happens for a reason and that everything happens for a purpose. we might not know it that that point in time but sooner or later youll find out. Failure is just passing everything will just go as it should be. take time to reflect and discern what to do next time to avoid failure this is only one thing is for sure, through failure we will learn from our mistakes, there will be many things that we discover in our self and that somehow will know that we are strong to accept such pain. In failure there is a opportunity to improve and be better the next time ...

Based on data from our study, the FQ treatment failure rate was only 0.8% in the low MIC group and 6.9% in the high MIC group. Although the failure rate was not high, the patients with high MIC-FQSEC UTIs was seven times more likely to experience treatment failure after adjusting for underlying cerebrovascular disease.. Based on this finding, FQ therapy should be carefully given to only FQSEC-UTI cases with a low risk for reduced FQ susceptibility. Use a higher dose of FQ may resolve this problem. However, the US Food and Drug Administration has recently advised to avoid FQ therapy for mild conditions including uncomplicated UTIs because of its serious side effects. FQs should be reserved for only those who do not have alternative treatment options.. We believe that our study has several strengths. First, our study definition to identify ambulatory FQSEC UTIs has shown promising discrimination ability in our pilot study (87.8% sensitivity and 85.7% specificity). For this reason, only patients ...
The high failure rate (e.g., 50%-60%) of phase III trials in oncology presents a major obstacle to the drug discovery process (1). Understanding and addressing the potential reasons for these high failure rates are crucial to making progress. Possible reasons for the high failure rate in phase III trials include (i) suboptimal choice of patient population and (ii) inaccurate predictions of effectiveness from the hypothesis generating prior phase II trials. The focus of this work is on the second of these reasons, and focuses on the choice of the endpoints used for phase II trials in patients with measurable disease to identify agents worthy of further evaluation. Our goal was to consider alternative phase II endpoints to the standardly used endpoint of tumor response, and in particular the use of endpoints based on continuous tumor measurements.. Historically, phase II trials have used tumor response rate as the primary endpoint, where response is assessed via the Response Evaluation Criteria in ...
Virologic failure occurred most frequently in individuals aged 18 to 19 years and concentrated around the time of transition to adult care (OR, 4.26, 95% CI, 1.12-16.28, p = 0.03). Individuals who were not able to independently adhere to their ART were especially likely to experience virologic failure (OR, 6.89; 95% CI, 2.57-18.5, p , 0.001), as were individuals with a poor knowledge of HIV (OR, 5.15; 95% CI, 2.16-12.3, p , 0.001), though only two individuals fell into this category. Low educational attainment was also identified as a risk failure for sustained viral breakthrough. Half of participants experienced virologic failure as children, and a third of these individuals experienced a sustained rebound in viral load after transition. Only two individuals who did not experience treatment failure as children subsequently has virological breakthrough as adults. As regards loss to follow-up after transition, individuals who had child protection services involved in their paediatric care were ...
