International cross-cultural development and field testing of the primary care practice questionnaire for the PaRIS survey (PaRIS-PCPQ)

BackgroundThe PaRIS survey, an initiative of the Organisation for Economic Co-operation and Development (OECD), aims to assess health systems performance in delivering primary care by measuring the care experiences and outcomes of people over 45 who used primary care services in the past six months. In addition, linked data from primary care practices are collected to analyse how the organisation of primary care practices and their care processes impact care experiences and outcomes. This article describes the development and validation of the primary care practice questionnaire for the PaRIS survey, the PaRIS-PCPQ.MethodThe PaRIS-PCPQ was developed based on domains of primary care practice and professional characteristics included in the PaRIS conceptual framework. Questionnaire development was conducted in four phases: (1) a multi-step consensus-based development of the source questionnaire, (2) translation of the English source questionnaire into 17 languages, (3) cross-national cognitive testing with primary care professionals in participating countries, and (4) cross-national field-testing.Results70 items were selected from 7 existing questionnaires on primary care characteristics, of which 49 were included in a first draft. Feedback from stakeholders resulted in a modified 34-item version (practice profile, care coordination, chronic care management, patient follow-up, and respondent characteristics) designed to be completed online by medical or non-medical staff working in a primary care practice. Cognitive testing led to changes in the source questionnaire as well as to country specific localisations. The resulting 32-item questionnaire was piloted in an online survey and field test. Data from 540 primary care practices from 17 countries were collected and analysed. Final revision resulted in a 34-item questionnaire.ConclusionsThe cross-national development of a primary care practice questionnaire is challenging due to the differences in care delivery systems. Rigorous translation and cognitive testing as well as stakeholder engagement helped to overcome most challenges. The PaRIS-PCPQ will be used to assess how key characteristics of primary care practices relate to the care experiences and outcomes of people living with chronic conditions. As such, policymakers and care providers will be informed about the performance of primary care from the patient’s perspective.

The predictive value of systemic immune-inflammation index for vascular access survival in chronic hemodialysis patients

ObjectiveTo examine the prognostic values of systemic immune-inflammation indices of hemodialysis (HD) vascular access failure and develop a prediction model for vascular access failure based on the most pertinent systemic immune-inflammation index.Study designA prospective cohort study.Setting & participantsPatients undergoing autogenous HD vascular access surgeries or arteriovenous graft as a permanent hemodialysis access in a tertiary center in southwest China from January 2020 to June 2022.PredictorsSystemic immune-inflammation indices, including NLR, dNLR, AAPR, SIRI, SII, PNI, PLR, and LIPI, and clinical variables.OutcomesThe outcome was defined as survival of the hemodialysis access, with both occluded and stenotic access being considered as instances of access failure.Analytical approachCox proportional hazard regression model.Results2690 patients were included in the study population, of whom 658 experienced access failure during the follow-up period. The median duration of survival for HD vascular access was 18 months. The increased systemic immune-inflammation indices, including dNLR, NLR, SII, PNI, SIRI, PLR, and LIPI, are predictive of HD access failure, with SII demonstrating the strongest prognostic value. A simple SII-based prediction model for HD access failure was developed, achieving C-indexes of 0.6314 (95% CI: 0.6249 – 0.6589) and 0.6441 (95% CI: 0.6212 – 0.6670) for predicting 6- and 12-month access survival, respectively.ConclusionsSystemic immune-inflammation indices are significantly and negatively associated with HD vascular access survival. A simple SII-based prediction model was developed and anticipates further improvement through larger study cohort and validation from diverse centers.

The ECG abnormalities in persons with chronic disorders of consciousness.

We aimed to investigate the electrocardiogram (ECG) features in persons with chronic disorders of consciousness (DOC, ≥ 29days since injury, DSI) resulted from the most severe brain damages. The ECG data from 30 patients with chronic DOC and 18 healthy controls (HCs) were recorded during resting wakefulness state for about five minutes. The patients were classified into vegetative state (VS) and minimally conscious state (MCS). Eight ECG metrics were extracted for comparisons between the subject subgroups, and regression analysis of the metrics were conducted on the DSI (29-593days). The DOC patients exhibit a significantly higher heart rate (HR, p = 0.009) and lower values for SDNN (p = 0.001), CVRR (p = 0.009), and T-wave amplitude (p < 0.001) compared to the HCs. However, there're no significant differences in QRS, QT, QTc, or ST amplitude between the two groups (p > 0.05). Three ECG metrics of the DOC patients-HR, SDNN, and CVRR-are significantly correlated with the DSI. The ECG abnormalities persist in chronic DOC patients. The abnormalities are mainly manifested in the rhythm features HR, SDNN and CVRR, but not the waveform features such as QRS width, QT, QTc, ST and T-wave amplitudes.

Mutational profile of previously treated chronic lymphocytic leukemia patients progressing on acalabrutinib or ibrutinib.

Chronic lymphocytic leukemia (CLL) progression during Bruton tyrosine kinase (BTK) inhibitor treatment is typically characterized by emergent B-cell receptor pathway mutations. Using peripheral blood samples from relapsed/refractory CLL patients in ELEVATE-RR (NCT02477696) (median 2 prior therapies), we report clonal evolution data for patients progressing on acalabrutinib or ibrutinib (median follow-up 41 months). Paired (baseline and progression) samples were available for 47 (excluding 1 Richter) acalabrutinib-treated and 30 (excluding 6 Richter) ibrutinib-treated patients. At progression, emergent BTK mutations were observed in 31 (66%) acalabrutinib-treated and 11 (37%) ibrutinib-treated patients (median variant allele fraction [VAF]: 16.1% vs 15.6%). BTK C481S mutations were most common in both groups; T474I (n = 9; 8 co-occurring with C481) and the novel E41V mutation within the pleckstrin homology domain of BTK (n = 1) occurred with acalabrutinib, while neither mutation occurred with ibrutinib. L528W and A428D co-mutations presented in one ibrutinib-treated patient. Pre-existing TP53 mutations were present in 25 (53.2%) acalabrutinib-treated and 16 (53.3%) ibrutinib-treated patients at screening. Emergent TP53 mutations occurred with acalabrutinib and ibrutinib (13% vs 7%; median VAF: 6.0% vs 37.3%, respectively). Six acalabrutinib-treated patients and one ibrutinib-treated patient had emergent TP53/BTK co-mutations. Emergent PLCG2 mutations occurred in 3 (6%) acalabrutinib-treated and 6 (20%) ibrutinib-treated patients. One acalabrutinib-treated patient and 4 ibrutinib-treated patients had emergent BTK/PLCG2 co-mutations. While common BTK C481 mutations were observed with both treatments, patterns of mutation and co-mutation frequency, mutation VAF, and uncommon BTK variants varied with acalabrutinib (T474I and E41V) and ibrutinib (L528W, A428D) in this patient population.

Evaluation of hepatic injury in chronic hepatitis B and C Using APRI and FIB-4 indices compared to fibroscan results

Background: Hepatitis B (HBV) and hepatitis C viruses (HCV) are significant causes of liver disease worldwide. Liver fibrosis (LF) is a complication of chronic liver damage caused by HBV and HCV due to our limited knowledge comparing the diagnostic performance of platelet to aspartate aminotransferase ratio index (APRI) and fibrosis-4 (FIB-4) index with fibroscan. Methods: This study evaluated liver damage in HBV and HCV using APRI, FIB4, and fibroscan indices. This retrospective cohort descriptive-analytical study was conducted on patients with HBV and HCV. This study uses laboratory results and imaging to investigate liver damage in chronic HBV and HCV patients. APRI and FIB-4 were computed based on laboratory results. Results: A total of 185 patients (82 hepatitis B and 103 hepatitis C) were included in the study. Thirteen patients had liver cirrhosis. There was no statistically significant difference between the fibroscan results in the two groups (P=0.99). The HBV group’s mean APRI and FIB-4 were lower than HCV, but no significant difference was observed (P&gt;0.05). Our results in HBV and HCV patients showed that APRI and FIB-4 accomplished well anticipating cirrhosis with an AUC of 0.771-0.845 and 0.871-0.910, respectively. Conclusion: Fibroscan is a powerful tool superior to APRI and FIB-4 in predicting LF and cirrhosis. Nevertheless, APRI and FIB-4 are inexpensive and non-invasive indicators with acceptable efficacy in predicting advanced fibrosis or cirrhosis. However, these two measures are not reliable in low-grade fibrosis.

Effectiveness of photodynamic therapy on the treatment of chronic periodontitis: a systematic review during 2008–2023

ObjectiveThis study investigated the effect of photodynamic therapy on chronic periodontitis patients and then evaluated the microbial, immunological, periodontal, and clinical outcomes. The significant effects of photodynamic therapy obtained by in vitro and in vivo studies have made it a popular treatment for periodontal diseases in recent years. Photodynamic therapy is a novel bactericidal strategy that is stronger, faster, and less expensive than scaling and root planing.MethodThis study registered on PROSPERO (CRD42021267008) and retrieved fifty-three randomized controlled trials by searching nine databases (Medline, Embase, Scopus, Open Gray, Google Scholar, ProQuest, the Cochrane Library, Web of Science, and ClinicalTrials.gov) from 2008 to 2023. Of 721 records identified through database searches following title and full-text analysis, and excluding duplicate and irrelevant publications, 53 articles were included in this systematic review. Fifty of the 53 eligible studies fulfilled all the criteria in the Joanna Briggs Institute’s (JBI’s) Checklist for RCTs; the remaining articles met 9–12 criteria and were considered high quality.ResultsThe present study showed that photodynamic therapy in adjunct to scaling and root planing has the potential to improve periodontal parameters such as clinical attachment loss or gain, decrease in bleeding on probing, and probing pocket depth. In addition, photodynamic therapy decreases the rate of periodontal pathogens and inflammation markers, which, in turn, reduces the progression of periodontitis.ConclusionPhotodynamic therapy is considered a promising, adjunctive, and low-cost therapeutic method that is effective in tissue repair, reducing chronic periodontitis, reducing inflammation, and well-tolerated by patients.

Quality of life and strength, but not cytokines, are associated with DAS-28 in active and inactive rheumatoid arthritis

Objective: Evaluate and correlate data between relevant cytokines, disease progression, and handgrip and quality of life among RA patients at different stages of disease progression. Method: Thirty-three RA patients were recruited for analysis, using comparisons and correlations, between levels of circulating cytokines (IFN-γ, TNF-α, IL-4, IL-6, IL-10, IL-17, IL-1β, and TNF receptors I and II), activity of the disease (evaluated using the DAS-28), handgrip (Hydraulic dynamometer), and quality of life (SF-36). Result: RA patients in different disease stages showed increases of IL-6 and IL-10 compared control group. Positive correlation between IL-6 with TNF-α, and IL-4 with IL-10 was found. Handgrip strength and quality of life were not related to cytokine levels. However, remission patients had better strength and quality of life indices compared to the active patients. In addition, handgrip of the non-dominant side, physical functions, role limitations physical health, pain, energy/fatigue and social functions have a negative correlation with the DAS28-PCR. Conclusion: High levels of IL-6 and IL-10 were observed in the chronic RA patients, but the values did not show correlation with disease activity, handgrip strength and quality of life. Disease activity show correlation with handgrip strength and quality of life. Furthermore, remission patients had better strength and quality of life indices compared to the active patients.

A nation-wide medical record database study: Value of hepatitisB surface antigen loss in chronic hepatitisB patients in Japan.

HepatitisB surface antigen (HBsAg) seroclearance is considered to be one of the best surrogate endpoints of functional cure for hepatitisB virus (HBV) infection. However, evidence regarding the relationship between achieving HBsAg seroclearance or a low baseline HBsAg level, and long-term clinical outcomes in Japanese patients with chronic HBV infection remains to be confirmed in a real-world setting. A retrospective observational cohort study was performed with an electronic medical record database, including data from 230 hospitals across Japan. Chronic HBV infection was defined as two consecutive, positive HBsAg laboratory measurements for HBV infection. The date of the second positive was used as a baseline to identify subsequent HBsAg seroclearance and liver disease progression. In the database, 2523 patients with chronic HBV infection were identified as the chronic hepatitisB (CHB) cohort. Among the CHB cohort with an average observational period of 5.19±3.87years, 202 patients (8%) achieved HBsAg seroclearance after baseline. They had a lower risk of developing hepatocellular carcinoma (HCC) (adjusted hazard ratio [aHR] 0.206, p<0.01) and cirrhosis (aHR 0.361, p<0.01). When the CHB cohort was stratified into two groups based on baseline HBsAg levels (<100IU/mL and ≥100IU/mL), patients with a lower baseline level of HBsAg (<100IU/mL) had a lower risk of developing liver disease (HCC aHR 0.600, p<0.01; cirrhosis aHR 0.618, p<0.05). These results confirm the clinical significance of HBsAg seroclearance and low HBsAg level at baseline with respect to long-term outcomes of patients with CHB in the Japanese population.

Integrating Smartphone Sensor Technology to Enhance Fine Motor and Working Memory Skills in Pediatric Obesity: A Gamified Approach

Childhood obesity remains a pervasive global challenge, often accompanied by deficits in working memory and fine motor skills among affected children. These deficits detrimentally impact academic performance. Despite limited evidence, home-based interventions targeting both fine motor skills and working memory remain underexplored. Leveraging game-based approaches holds promise in behavior modification, self-management of chronic conditions, therapy adherence, and patient monitoring. In this study, a novel smartphone-based game was meticulously developed to target the enhancement of working memory and fine motor skills in a cohort of thirty-two obese or overweight children. Over two weeks, participants engaged in regular gameplay sessions within the comfort of their homes. Pretest and post-test assessments yielded compelling evidence of significant improvements, with statistical significance established at a robust 95% confidence level. Notably, participants exhibited a progressive trend of improvement in their gameplay performance. Recognizing the profound impact of academic achievement on future socioeconomic trajectories, regardless of weight management outcomes, the importance of bolstering cognitive skills cannot be overstated. This innovative intervention offers a pragmatic and cost-effective solution to empower children to cultivate essential cognitive abilities within their home environment. By fostering the development of working memory and fine motor skills, this intervention holds promise in facilitating improved academic performance and, consequently, enhancing long-term prospects for these children.

"Spanish flu," encephalitis lethargica, and COVID-19: Progress made, lessons learned, and directions for future research.

One hundred years ago, an influenza pandemic swept across the globe that coincided with the development of a neurological condition, named "encephalitis lethargica" for the occurrence of its main symptom, the sudden onset of sleepiness that either developed into coma or gradually receded. Between 1917 and 1920, mortality of the flu was >20 million and of encephalitis lethargica approximately 1 million. For lessons to be learned from this pandemic, it makes sense to compare it with the COVID-19 pandemic, which occurred 100 years later. Biomedical progress had enabled testing, vaccinations, and drug therapies accompanied by public health measures such as social distancing, contact tracing, wearing face masks, and frequent hand washing. From todays' perspective, these public health measures are time honored but not sufficiently proven effective, especially when applied in the context of a vaccination strategy. Also, the protective effects of lockdowns of schools, universities, and other institutions and the restrictions on travel and personal visits to hospitals or old-age homes are not precisely known. Preparedness is still a demand for a future pandemic. Clinical trials should determine the comparative effectiveness of such public health measures, especially for their use as a combination strategy with vaccination and individual testing of asymptomatic individuals. It is important for neurologists to realize that during a pandemic the treatment possibilities for acute stroke and other neurological emergencies are reduced, which has previously led to an increase of mortality and suffering. To increase preparedness for a future pandemic, neurologists play an important role, as the case load of acute and chronic neurological patients will be higher as well as the needs for rehabilitation. Finally, new chronic forms of postviral disease will likely be added, as was the case for postencephalitic parkinsonism a century ago and now has occurred as long COVID.

Quality and safety actions in primary care practices in COVID-19 pandemic: the PRICOV-19 study in Spain

BackgroundPrimary Health Care (PHC) has been key element in detection, monitoring and treatment of COVID-19 cases in Spain. We describe how PHC practices (PCPs) organized healthcare to guarantee quality and safety and, if there were differences among the 17 Spanish regions according to the COVID-19 prevalence.MethodsCross-sectional study through the PRICOV-19 European Online Survey in PCPs in Spain. The questionnaire included structure and process items per PCP. Data collection was due from January to May 2021. A descriptive and comparative analysis and a logistic regression model were performed to identify differences among regions by COVID-19 prevalence (low < 5% or high ≥5%).ResultsTwo hundred sixty-six PCPs answered. 83.8% of PCPs were in high prevalence regions. Over 70% PCPs were multi-professional teams. PCPs attended mainly elderly (60.9%) and chronic patients (53.0%). Regarding structure indicators, no differences by prevalence detected. In 77.1% of PCPs administrative staff were more involved in providing recommendations. Only 53% of PCPs had a phone protocol although 73% of administrative staff participated in phone triage. High prevalence regions offered remote assessment (20.4% vs 2.3%, p 0.004) and online platforms to download administrative documents more frequently than low prevalence (30% vs 4.7%, p < 0.001).More backup staff members were hired by health authorities in high prevalence regions, especially nurses (63.9% vs 37.8%, p < 0.001. OR:4.20 (1.01-8.71)). 63.5% of PCPs provided proactive care for chronic patients. 41.0% of PCPs recognized that patients with serious conditions did not know to get an appointment.Urgent conditions suffered delayed care in 79.1% of PCPs in low prevalence compared to 65.9% in high prevalence regions (p 0.240). A 68% of PCPs agreed on having inadequate support from the government to provide proper functioning. 61% of high prevalence PCPs and 69.5% of low ones (p: 0.036) perceived as positive the role of governmental guidelines for management of COVID-19.ConclusionsSpanish PCPs shared a basic standardized PCPs’ structure and common clinical procedures due to the centralization of public health authority in the pandemic. Therefore, no relevant differences in safety and quality of care between regions with high and low prevalence were detected. Nurses and administrative staff were hired efficiently in response to the pandemic. Delay in care happened in patients with serious conditions and little follow-up for mental health and intimate partner violence affected patients was identified. Nevertheless, proactive care was offered for chronic patients in most of the PCPs.

Measuring the perceived wellbeing of hemodialysis patients: A Mind Genomics cartography.

Chronic Kidney Disease patients under hemodialysis have high morbidity rate, which tends to considerably affect their health-related quality of life. Multiple studies that have made use of different questionnaries report the poor life quality of this patient group. The research in hand implemented the Mind Genomics Approach as a method to asses the health-related quality of life of hemodialysis patients, while relying on conjoint measurements to group individuals with similar patterns of responses to a certain mindset. The study is conducted in 3 clinics with 219 patients. It uncovers three clusters or mindsets: Mindset 1- Feels guardedly optimistic but worried about money, Mindset 2-Feels strongly positive because the state guarantees and the family supports, Mindset 3-Feels positive only about money. Based on the analysis of the collected data, the findings of this study suggest that the quality of life in hemodialysis patients is highly correlated to their financial status. The current study is one of the few first attempts to apply Mind Genomics in medical settings and the first, to our knowledge, in hemodialysis centers. This technology might enable healthcare proffesionals to provide personalized psychological treatment and additional social support to patients, which in turn could improve their clinical outcomes. The study is an example of using technology as a service.

Cough Response to High-Dose Inhaled Corticosteroids in Patients with Chronic Cough and Fractional Exhaled Nitric Oxide Levels ≥ 25ppb: A Prospective Study.

This study aimed to investigate the effects of high-dose inhaled corticosteroids (ICS) on chronic cough patients with elevated fractional exhaled nitric oxide (FeNO) levels. In a prospective study, adults with chronic cough and FeNO ≥ 25ppb, without any other apparent etiology, received fluticasone furoate (200 mcg) for three weeks. Outcomes were evaluated using FeNO levels, cough severity, and Leicester Cough Questionnaire (LCQ) before and after treatment. Of the fifty participants (average age: 58.4years; 58% female), the treatment responder rate (≥ 1.3-point increase in LCQ) was 68%, with a significant improvement in cough and LCQ scores and FeNO levels post-treatment. However, improvements in cough did not significantly correlate with changes in FeNO levels. These findings support the guideline recommendations for a short-term ICS trial in adults with chronic cough and elevated FeNO levels, but the lack of correlations between FeNO levels and cough raises questions about their direct mechanistic link.

Pulmonary artery pressure monitoring in chronic heart failure: effects across clinically relevant subgroups in the MONITOR-HF trial.

In patients with chronic heart failure (HF), the MONITOR-HF trial demonstrated the efficacy of pulmonary artery (PA)-guided HF therapy over standard of care in improving quality of life and reducing HF hospitalizations and mean PA pressure. This study aimed to evaluate the consistency of these benefits in relation to clinically relevant subgroups. The effect of PA-guided HF therapy was evaluated in the MONITOR-HF trial among predefined subgroups based on age, sex, atrial fibrillation, diabetes mellitus, left ventricular ejection fraction, HF aetiology, cardiac resynchronisation therapy, and implantable cardioverter defibrillator. Outcome measures were based upon significance in the main trial and included quality of life, clinical, and PA pressure endpoints, and were assessed for each subgroup. Differential effects in relation to the subgroups were assessed with interaction terms. Both unadjusted and multiple testing adjusted interaction terms were presented. The effects of PA monitoring on quality of life, clinical events, and PA pressure were consistent in the predefined subgroups, without any clinically relevant heterogeneity within or across all endpoint categories (all adjusted interaction P-values were nonsignificant). In the unadjusted analysis of the primary endpoint quality-of-life change, weak trends towards a less pronounced effect in older patients (Pinteraction = 0.03; adjusted Pinteraction = 0.33) and diabetics (Pinteraction = 0.01; adjusted Pinteraction = 0.06) were observed. However, these interaction effects did not persist after adjusting for multiple testing. This subgroup analysis confirmed the consistent benefits of PA-guided HF therapy observed in the MONITOR-HF trial across clinically relevant subgroups, highlighting its efficacy in improving quality of life, clinical, and PA pressure endpoints in chronic HF patients.

The socio-economic burden of H1-antihistamine-refractory chronic spontaneous urticaria in Germany.

Data from the AWARE study (A Worldwide Antihistamine-Refractory chronic urticaria patient Evaluation) illustrate a substantial disease burden in German patients with H1-antihistamine (-H1-AH)-refractory chronic spontaneous urticaria (CSU). Detrimental effects on patients' quality of life, poor disease control and impairment in the ability to work and perform other daily activities are reported. Based on these findings, this study aims to quantify the epidemiological and socio-economic burden of H1-AH-refractory CSU in Germany. To determine the epidemiological burden of H1-AH-refractory CSU, the age- and gender-specific prevalence of CSU and the proportion of H1-AH-refractory patients in Germany anonymized data from the InGef research database have been used. In a second step, the socio-economic burden in terms of lost numbers of hours in paid and unpaid work was calculated by extrapolating the age- and gender-specific work productivity and activity impairment (WPAI) observed in AWARE to the H1-AH-refractory CSU population in Germany. Finally, productivity losses in paid and unpaid work were monetized using the human capital and the friction cost approach respectively. Moreover, socio-economic burden was calculated depending on symptom control of the patients (measured by urticaria control test [UCT]). In Germany, over 203,000 patients (20 years or older) had H1-AH-refractory CSU in 2018. The avoided lost paid and unpaid work hours attributable to H1-AH-refractory CSU summed up to over 100 million. Overall, the socio-economic burden of H1-AH-refractory CSU in monetary terms was evaluated at € 2.2 billion and the majority of this was due to unpaid work loss. Patients with poor disease control, as indicated by UCT score < 12, were more likely to suffer from high impairment than patients with controlled disease, resulting in a higher socio-economic burden. The results of our analyses picture the substantial socio-economic burden of H1-AH-refractory CSU and therefore the tremendous impact it has on daily lives of individuals and society overall.

Sustained virological response in chronic hepatitis C patients by direct-acting antiviral treatment significantly reduces liver stiffness over 24 weeks posttreatment.

To investigate whether direct-acting antiviral (DAA) treatment affected liver fibrosis testing, including transient elastography (TE), aspartate aminotransferase-to-platelet ratio index (APRI), and Fibrosis-4 (FIB-4) index, after establishing a sustained virological response for 24 weeks. This prospective cohort study was conducted between October 1, 2019, and September 30, 2020, at Rajavithi Hospital, Bangkok, Thailand. All the patients had significant liver fibrosis (TE ≥ 7.0 kPa) at baseline and completed 12 weeks of DAA therapy. After achieving SVR, liver stiffness measurements were repeated for at least 24 weeks. The primary outcome was a > 30% improvement in TE score at the end of the study compared to baseline. A multivariate logistic regression model was used to identify the parameters associated with the primary outcome. Temporal changes in APRI and FIB-4 indices from baseline to 24 weeks posttreatment were also examined. A total of 110 chronic HCV patients were included in our cohort, of which 57 (52.3%) achieved the primary outcome. The median TE decreased from 15.05 (8.76-23.68) kPa at pretreatment to 9.60 (6.50-14.40) kPa at 24 weeks posttreatment (P < .001). Those who had a baseline TE ≥ 9.5 kPa had higher odds of meeting the primary outcome, and this remained significant after adjusting for age, sex, baseline body mass index, underlying diabetes mellitus, HCV genotype 3, baseline laboratory levels, and treatment regimens (OR 3.04; 95% CI 1.22-7.60, P = .017). Similar to TE, the median APRI and FIB-4 index displayed a considerable reduction from baseline to 24 weeks after successful therapy. Modern DAA treatment has been associated with considerable improvement in liver stiffness measured by TE in chronic HCV patients who achieve SVR, with roughly 52% of patients experiencing a reduction of > 30% in TE over 24 weeks posttreatment compared to baseline. This probably indicates early fibrosis regression, although the effect of resolution of inflammation after treatment completion cannot be ruled out.
