Abstract
RATIONALE Diffuse alveolar hemorrhage (DAH) is a life-threatening manifestation of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). The Plasma Exchange (PLEX) and Glucocorticoids (GC) in Severe AAV (PEXIVAS;NCT00987389) trial was the largest in AAV and first to enroll participants with DAH requiring mechanical ventilation. OBJECTIVES Evaluate characteristics, treatment effects, outcomes for patients with AAV with and without DAH. METHODS PEXIVAS randomized 704 participants to PLEX or no-PLEX and reduced or standard-dose GC. DAH status was defined at enrollment as no-DAH, non-severe, or severe (room air SpO(2)≤85% or use of mechanical ventilation). MEASUREMENTS AND MAIN RESULTS At enrollment, 191(27.1%) participants had DAH (61 severe, including 29 ventilated) and were younger, more frequently relapsing, PR3-ANCA positive, and had lower serum creatinine but were more frequently dialyzed than participants without DAH (n=513,72.9%). Among those with DAH, 8/95(8.4%) receiving PLEX died within one year vs. 15/96(15.6%) with no-PLEX (HR 0.52,CI 0.21-1.24), while 13/96(13.5%) receiving reduced-GC died vs. 10/95(10.5%) with standard-GC (HR 1.33,CI 0.57-3.13). When ventilated, ventilator-free days were similar with PLEX vs. no-PLEX (medians 25,IQR 22-26 vs. 22-27), fewer with reduced-GC (23[20-25]) vs. standard-GC (26[25-28]). Treatment effects on mortality did not vary by presence or severity of DAH. Overall, 23/191(12.0%) with DAH died within one year vs. 34/513(6.6%) without DAH. End-stage kidney disease and serious infections did not differ by DAH status or treatments. CONCLUSION Patients with AAV and DAH differ from those without DAH in multiple ways. Further data are required to confirm or refute a benefit of PLEX or GC dosing on mortality. Clinical trial registration available at www. CLINICALTRIALS gov, ID: NCT00987389.

Roxadustat reduces left ventricular mass index compared to rHuEPO in haemodialysis patients in a randomized controlled trial
Tan, W., Wang, X., Sun, Y., Wang, X., He, J., Zhong, L., Jiang, X., Sun, Y., Tian, E., Li, Z., et al
Journal of internal medicine. 2024
Abstract
BACKGROUND Left ventricular hypertrophy (LVH) is highly prevalent in haemodialysis (HD) patients and is associated with an increased risk of death. Roxadustat and recombinant human erythropoietin (rHuEPO, abbreviated as EPO) are the main treatment strategies for renal anaemia in HD patients, but it has not been clear whether there is a difference in their effect on LVH. METHODS In this multi-centre, prospective, randomized trial of 12-month duration, study participants were randomized in a 1:1 ratio to the roxadustat group or the EPO group. The doses of both treatment regimens were adjusted so that the patients had a haemoglobin level of 10.0-12.0 g per dL. The primary study endpoint was the change from baseline to 12 months in the left ventricular mass index (LVMI, g/m(2) ) measured by echocardiography. RESULTS In total, 114 patients were enrolled. The mean age was 50 years, and the median dialysis duration was 33 months. Sixty-one patients were men, and 24 were diabetic. LVMI decreased from 116.18 ± 27.84 to 110.70 ± 25.74 g/m(2) in the roxadustat group. However, it increased from 109.35 ± 23.41 to 114.99 ± 28.46 g/m(2) in the EPO group, with a significant difference in the change in LVMI between the two groups [-5.48 (-11.60 to 0.65) vs. 5.65 (0.74 to 10.55), p < 0.05]. Changes in left ventricular mass, end-diastolic volume and 6-min walk test seemed superior in the roxadustat group. There were no significant differences in other cardiac geometry, biochemical parameters and major adverse cardiovascular events between the two groups. CONCLUSIONS Compared to EPO, roxadustat is more helpful in the regression of LVH in HD patients.

Sharma, G. K., Patil, A., Kaur, P., Rajesh, S., Drakonaki, E., Botchu, R.
Journal of ultrasound. 2024
Abstract
PURPOSE To assess whether Ultrasound guided dry needling is adequate for both common extensor tendon tears and tendinosis or whether ultrasound guided platelet rich plasma (PRP) has a superior outcome when compared to dry needling when there are tears of the common extensor tendon. MATERIALS AND METHODS This is a single-centre, single-blinded, randomised controlled trial conducted between November 2018 and April 2020. 40 patients diagnosed with lateral epicondylitis based on clinical and sonographic features and having comparable baseline characteristics were randomly assigned to the two study groups (dry needling and PRP). Inclusion criteria were patients aged 20 years or more who were symptomatic for at least 3 months with sonographic evidence of lateral epicondylitis. Exclusion criteria were complete tear of common extensor tendon confirmed on ultrasound and presence of other associated diseases like osteoarthritis of shoulder and elbow. RESULTS There was significant improvement in the visual analogue scale pain score in PRP group compared to the dry needling group at 9 months. However, this difference was not evident at 3 and 6 months follow-up. Mean improvement in common extensor tendon thickness in PRP group (5.1 mm at 3 months and 4.3 mm at 6 months) was slightly better than dry needling (4.4 mm at 3 months and 4.0 mm at 6 months). There was no difference in tear (if present) healing between both groups at 3 months. However at 6 months follow up, PRP demonstrated significant (mean-2.5) healing in tear compared to dry needling (mean-3.1). CONCLUSION Two injections of Ultrasound guided PRP are more beneficial non operative treatment compared to ultrasound guided dry needling, in lateral epicondylitis.

Scientific reports. 2024;14(1):1128
Abstract
To assess the clinical efficacy of Double Filtration Plasmapheresis (DFAPP), a novel blood purification method, in treating hyperlipidemic moderate/severe pancreatitis (HL-M/SAP). A total of 68 HL-M/SAP patients were enrolled in this study. The observation group, comprising 34 patients, received DFAPP treatment, while the control group underwent CVVH + PA treatment. We compared the efficacy changes between the two groups post-treatment. Patients treated with DFAPP showed significant improvements in clinical outcomes. After 72 h of DFAPP treatment, HL-M/SAP patients exhibited notably lower multiple organ failure scores and a reduced mortality rate compared to those in the CVVH + PA group. Triglyceride levels in HL-M/SAP patients treated with DFAPP for 48 h averaged 3.75 ± 1.95, significantly lower than the 9.57 ± 3.84 levels in the CVVH + PA group (P < 0.05). Moreover, CRP levels decreased markedly, IL-17 levels diminished, IL-10 levels increased, and the decline in IL-35 levels was significantly less pronounced compared to the CVVH + PA group. The recurrence rate of pancreatitis was also significantly lower after 6 months. The early implementation of DFAPP in HL-M/SAP patients effectively reduces triglyceride levels, suppresses pro-inflammatory factors, enhances anti-inflammatory factors, and mitigates cytokine storm-induced sepsis damage. Consequently, this leads to a decrease in the incidence of multiple organ failure, improved patient survival rates, and a reduce the recurrence rate of lipogenic pancreatitis.Trial registration: Chinese Clinical Trial Registry, ChiCTR2300076066.

Abstract
A rotator cuff tear is a prevalent ailment affecting the shoulder joint. The clinical efficacy of combined therapy remains uncertain for partial rotator cuff tears. In this study, we integrated extracorporeal shockwave therapy (ESWT) with platelet-rich plasma (PRP) injection, juxtaposed with PRP in isolation. Both cohorts exhibited significant improvements in visual analogue scale (VAS), Constant-Murley score (CMS), degrees of forward flexion, abduction, internal rotation, and external rotation, and the sum of range of motion (SROM) over the six-month assessment period. The application of ESWT in conjunction with PRP exhibited notable additional enhancements in both forward flexion (p = 0.033) and abduction (p = 0.015) after one month. Furthermore, a substantial augmentation in the range of shoulder motion (SROM) (p < 0.001) was observed after six months. We employed isobaric tag for relative and absolute quantitation (iTRAQ) to analyze the differential plasma protein expression in serum samples procured from the two groups after one month. The concentrations of S100A8 (p = 0.042) and S100A9 (p = 0.034), known to modulate local inflammation, were both lower in the ESWT + PRP cohort. These findings not only underscore the advantages of combined therapy but also illuminate the associated molecular changes.

Abstract
INTRODUCTION Anemia of chronic kidney disease (CKD) has a high incidence and is associated with many disease conditions. Iron dysmetabolism is an important contributor to anemia in CKD patients. METHODS ALTAI, a randomized, active-controlled, phase 4 trial, investigated the efficacy of roxadustat versus recombinant human erythropoietin (rHuEPO) on gastrointestinal iron absorption in patients with anemia of CKD (stage 4/5). The primary endpoint was change from baseline to day 15 in gastrointestinal iron absorption (serum iron area under the concentration-time curve; AUC(0-3h)) following single-dose oral iron. RESULTS Twenty-five patients with a mean age of 55.1 years were randomized 1:1 to roxadustat (n = 13) or rHuEPO (n = 12). Baseline iron profiles were similar between treatment groups. Change from baseline to day 15 in serum iron AUC(0-3h) was not statistically significantly different between the roxadustat and rHuEPO groups. Mean (SD) change from baseline in serum iron AUC(0-3h) was 11.3 (28.2) g × 3 h/dl in the roxadustat group and - 0.3 (9.7) g × 3 h/dl in the rHuEPO group. Roxadustat treatment was associated with decreased hepcidin and also increased transferrin, soluble transferrin receptor, and total iron-binding capacity (TIBC), with nominal significance. The proportion of patients experiencing one or more adverse events was 38.5% when treated with roxadustat and 16.7% with rHuEPO. CONCLUSIONS The study showed no significant difference between roxadustat and rHuEPO in iron absorption but was underpowered because of recruitment challenges.

Abstract
INTRODUCTION Iron deficiency anaemia (IDA) is the most common systemic manifestation of inflammatory bowel disease (IBD) that has detrimental effects on quality of life (QoL) and disease outcomes. Iron deficiency (ID), with or without anaemia, poses a diagnostic and therapeutic challenge in patients with IBD due to the multifactorial nature of ID(A) and its frequent recurrence. Elevated hepcidin-a systemic iron regulator that modulates systemic iron availability and intestinal iron absorption-has been associated with oral iron malabsorption in IBD. Therefore, hepcidin could assist in therapeutic decision-making. In this study, we investigate whether hepcidin can predict response to oral and intravenous iron supplementation in patients with active IBD undergoing anti-inflammatory treatment. METHODS AND ANALYSIS PRIme is an exploratory, multicentre, open-label and randomised trial. All adult patients with active IBD and ID(A) will be assessed for eligibility. The participants (n=90) will be recruited at five academic hospitals within the Netherlands and randomised into three groups (1:1:1): oral ferrous fumarate, oral ferric maltol or intravenous iron. Clinical and biochemical data will be collected at the baseline and after 6, 14 and 24 weeks. Blood samples will be collected to measure hepcidin and other biomarkers related to iron status. In addition, patient-reported outcomes regarding QoL and disease burden will be evaluated. The primary outcome is the utility of hepcidin as a predictive biomarker for response to iron therapy, which will be assessed using receiver operating curve analysis. ETHICS AND DISSEMINATION The study has been approved by the Institutional Review Board at the Leiden University Medical Center (IRB No. P21.109) and other study sites. All participants will provide written informed consent to enrol in the study. The findings will be published in a peer-reviewed journal and disseminated at scientific conferences; the dataset will be available on reasonable request. TRIAL REGISTRATION Prospectively registered in the https://clinicaltrials.gov/ and the Eudra registries. First submitted on 10 May 2022 to the ClinicalTrials.gov (ID: NCT05456932) and on 3 March 2022 to the European Union Drug Regulating Authorities Clinical Trials Database (ID: 2022-000894-16).

Abstract
(1) Background: Current treatments for knee osteoarthritis (KOA), such as intra-articular corticosteroids or hyaluronic acid (HA) injections, are controversial due to their ineffectiveness in preventing disease progression. Platelet-rich plasma (PRP) has become a promising and possible treatment for KOA. It is thought to enhance articular cartilage regeneration and reduce OA-related impairment. PRP contains growth factors such as PDGF-BB, which stimulates growth and inhibits joint damage. Based on numerous studies, after a certain amount of time, it was found that multiple PRP treatments reduced pain more than a single injection. This study evaluates the efficacy of multiple PRP (m-PRP) injections compared to multiple HA (m-HA) injections for KOA treatment, focusing on their correlation with PDGF-BB levels. (2) Methods: In this single-center, open-label, randomized, comparative clinical trial, 30 KOA patients received m-PRP and m-HA injections. VAS and WOMAC were used to evaluate clinical outcomes and PDGF-BB concentrations. (3) Results: The study analysis revealed a statistically significant reduction in pain indices. In both the m-PRP and m-HA groups after 12 weeks, m-PRP showed superior results. PDGF-BB concentrations also increased, with a strong negative correlation and statistical significance using Spearman's rho. (4) Conclusions: Multiple PRP injections are safe and associated with elevated PDGF-BB, reduced VAS and WOMAC scores, providing the potential for articular cartilage regeneration and inhibiting knee osteoarthritis progression.

Abstract
BACKGROUND For anemia management in patients with chronic kidney disease not on dialysis, darbepoetin alfa (DA), which has a shorter half-life but is more inexpensive than continuous erythropoietin receptor activator (CERA), is preferred in Korea. This study evaluated the efficacy, safety, and cost-effectiveness of once-in-4-weeks DA compared with once-in-4-weeks CERA in patients with chronic kidney disease not on dialysis. METHODS In this randomized, prospective, non-inferiority study, 40 erythropoiesis-stimulating agent-naïve patients with chronic kidney disease not on dialysis were randomized 1:1 to the DA group and CERA group. They received the study drug once in 4 weeks during 10- or 12-week correction period and 24-week efficacy evaluation period. The primary outcomes were the mean difference in the changes in hemoglobin levels between baseline and efficacy evaluation period and hemoglobin response rates during the correction period. The secondary outcomes included differences in adverse events and costs. RESULTS DA was non-inferior to CERA for anemia correction; the mean difference in the change in hemoglobin levels between the groups was -0.070 g/dL (95% confidence interval, -0.730 to 0.590 g/dL). Hemoglobin response rates were 100% with DA and 94.1% with CERA. Adverse events were comparable. The mean cost of DA was approximately one-third that of CERA (34,100 ± 7,600 Korean won/4 weeks vs. 115,500 ± 23,600 Korean won/4 weeks; p < 0.001). CONCLUSION Once-in-4-weeks DA safely corrects anemia in erythropoiesis-stimulating agent-naïve patients with chronic kidney disease not on dialysis and is more cost-effective than once-in-4-weeks CERA.

Abstract
BACKGROUND Several treatment modalities are available for the treatment of vitiligo due to the lack of a uniformly effective therapy. Topical latanoprost 0.005% is an effective topical treatment. Fractional CO(2) laser alone or combined with platelet-rich plasma (PRP) has been proposed as effective adjunctive therapies. OBJECTIVES We aimed to compare the efficacy of topical latanoprost 0.005% (Ioprost®, Orchidia, Egypt) combined with either add-on fractional CO(2) laser or fractional CO(2) -PRP versus topical latanoprost monotherapy in the treatment of localized stable vitiligo. PATIENTS/METHODS The study included 60 patients randomly assigned into three equal groups. Group A patients received topical latanoprost drops only. Group B patients received topical latanoprost drops and fractional CO(2) laser sessions at 2-week interval for 3 months. Group C patients received topical latanoprost drops and fractional CO(2) laser sessions combined with PRP at a 2-week interval for 3 months. The mean improvement score by the physician was calculated 4 months after the start of the study. Punch skin biopsies were obtained before treatment and 4 months from the beginning of the study and stained with H&E and HMB-45 antibody for evaluation of pigmentation. RESULTS Significant clinical improvement of vitiligo lesions with significant increase of re-pigmentation were reported in the three treated groups. Latanoprost in combination with fractional CO(2) and PRP was associated with more significant therapeutic outcomes than either combined latanoprost and fractional CO(2) or latanoprost alone. CONCLUSION Fractional CO(2) laser-PRP enhances the therapeutic efficacy of latanoprost 0.005% in the treatment of localized stable vitiligo.
