Early MOnitoring of REsponse (MORE) to Golimumab Therapy: Results of a Multicentre, Prospective Observational Trial.

BACKGROUND: The therapeutic goal of clinical remission in patients with moderate to severe ulcerative colitis (UC) is achieved after biological therapy only in 16-39%. Individualization of therapeutic intervention would benefit from prediction of early response. STUDY OBJECTIVE: The primary objective of our study was to assess golimumab (GLM) trough serum level of ≥2.5 µg/mL in combination with a reduction of faecal calprotectin (FC) of ≥50% at week 6 compared to baseline to predict clinical response at week 26 after regular GLM intake. METHODS: Patients with moderate to severe active UC and planned GLM treatment were recruited for a prospective, multicentre, observational study in Germany. Prediction of clinical response was assessed by FC and GLM trough level. Missing data were imputed as therapy failure according to the last observation carried forward method. RESULTS: Fifty nine patients have been enrolled. 54% of patients were anti-TNF naïve. Clinical response at week 6 was a significant predictor for achieving clinical response at week 26 (odds ratio [OR] 10.97, confidence interval [CI], 2.96-40.68; p < 0.001). Moreover, patients with a GLM trough level of ≥2.5 µg/mL and a ≥50% reduction of FC at week 6 had an OR of 5.33 (95% CI, 0.59-47.84) to achieve clinical response at week 26. CONCLUSION: Clinical response at week 6 is the best predictive marker for achieving clinical response at week 26. Consideration of significant reduction of FC and trough GLM serum levels could improve prediction of response.

Percutaneous Bioelectric Current Stimulation in the Treatment of Chronic Achilles Tendinopathy: Protocol for a Double-Blind, Placebo-Controlled Randomized Multicenter Trial.

BACKGROUND: The consensus for the optimal treatment strategy for chronic Achilles tendinopathy (AT) is still debated and treatment options are limited. This results in a significant medical need for more effective treatment options. OBJECTIVE: The aim of this study is to investigate the therapeutic effects of percutaneous bioelectric current stimulation (PBCS) on AT. METHODS: A multicenter, randomized, double-blind, placebo-controlled clinical trial will be conducted. A total of 72 participants with chronic (ie, >3 months) midpoint AT will be randomized and receive four PBCS sessions-either verum or placebo-over 3 weeks. Both groups will complete daily Achilles tendon loading exercises in addition to the intervention. Evaluation sessions will be completed at baseline and during the intervention (weeks 0-3). Self-reported outcome measures will be completed at follow-up at weeks 4, 12, 26, and 52. The primary outcomes are the Victorian Institute of Sports Assessment-Achilles questionnaire scores and statistical evaluation of intraindividual differences between baseline and 12-week evaluations after initial treatment of verum therapy compared to control. Secondary outcomes will assess Pain Disability Index scores; average pain, using the 11-point Numeric Rating Scale; return to sports; and use of emergency medication. RESULTS: The study began in May 2021. As of October 2022, we randomized 66 out of 72 participants. We anticipate completing recruitment by the end of 2022 and completing primary data analysis by March 2023. CONCLUSIONS: The study will evaluate the effects of PBCS on pain, physical function, and clinical outcomes.

Cell-Free Blood Cell Secretome (BCS) Counteracts Skin Aging: Multi-Center Prospective Regenerative Aesthetic Medicine Study Using Exokine®.

Background: The "Inflammation Theory of Ageing" identifies pro-inflammatory cytokines and oxidative damage as one cause of cellular and mitochondrial deterioration and aging. Cell-free blood cell secretome (BCS) also known as autologous conditioned serum (ACS) has shown anti-inflammatory and regenerative mode of action in musculoskeletal disorders and radicular compression. Aim: To confirm that BCS can improve signs of skin aging from a previous study in a multi-center setting. Methods: Prospective, one-armed, multi-center interventional therapeutic study. Ninety-five women with skin firmness loss were treated with four intra-dermal injection sessions in both cheeks at 0, 2, 4 and 6 weeks. BCS was processed with Exokine® medical device according to manufacturer's instructions. Primary endpoints were cutometric R0 and R3 at 12 and 24 weeks. GAIS, FACE-QTM, Patient Attractivity Self-Assessment and safety were evaluated. Results: Mean skin firmness (R0) improved significantly from baseline 0.40 mm to 0.38 mm at week 12 and to 0.36 mm at week 24. Mean skin tiring (R3) improved significantly from baseline 0.45 mm to 0.42 mm at week 12 and to 0.40 at week 24. FACE-QTM "Satisfaction with Skin" significantly improved from baseline to weeks 12, 24 and 48. So did "Satisfaction with Facial Appearance" and "Psychological and Social Function". "Satisfaction with Decision" and "Satisfaction with Outcome" were stable at week 24 and 48. At week 48 patients assessed their age 1.68 years younger vs Baseline. FACE-QTM aging appraisal improves from Baseline 52.94 to 65.23 at week 48. GAIS, by both physicians and patients, confirm improvement of skin. Conclusion: For up to 48 weeks four intra-dermal injections with cell-free BCS increase facial skin firmness and resilience to tiring and patients' satisfaction with their facial appearance and skin. Patients perceive their face as younger. BCS has the ability to sustainably rejuvenate facial skin safely. Study Registration: Registration on German clinical trials register: DRKS00013014.

Cell-Free Blood Cell Secretome (BCS) Counteracts Skin Aging and Restores Firmness and Elasticity.

BACKGROUND: Blood Cell Secretome, BCS (also Autologous Conditioned Serum, ACS) is efficacious in treatment of musculoskeletal disorders. It contains inflammation resolving cytokines, growth factors, exosomes, and lipid mediators. Skin aging is associated with reduced TGF-ß signaling and collagen synthesis and chronic (sub-acute) inflammation, among other factors. Pre-clinically, BCS counteracts these mechanisms, suggesting it as a treatment against cutaneous aging. OBJECTIVE: This 24-week study evaluated the effects of deep dermal to immediate sub-dermal micropuncture injections of cell-free BCS in patients with age-related reduced facial skin elasticity. METHODS: In this prospective, single-armed, mono-center study, 21 women underwent 4 BCS treatment sessions over 12 weeks with follow-up at 24 weeks. The primary endpoint was skin elasticity measured by cutometry. Secondary endpoints were safety, skin hydration, and aesthetic assessments using global aesthetic improvement scale. RESULTS: Skin firmness increased significantly between baseline and 12 weeks (P<0.001) and further increased by 24 weeks (P<0.001). Skin tiring was congruently reduced (P<0.001). Skin hydration and aesthetic ratings improved significantly. No BCS-related adverse reactions occurred. CONCLUSION: BCS treatment resulted in increased firmness and hydration, usually attributed to younger skin. BCS is potentially the first cell-free autologous therapy for skin rejuvenation derived from patients’ own blood. J Drugs Dermatol. 2021;20(6):682-688. doi:10.36849/JDD.5018.

Pain localization in cluster headache patients: Onset, peak, and radiation.

OBJECTIVE AND AIM: To describe differences in pain locations for onset, peak, and radiation aspects of cluster headache (CH) attacks. METHODS AND MATERIALS: Data were collected for 23 months using a cross-sectional online survey composed of 117 questions on pain location, demographics, and clinical features. 5260 datapoints on 44 pain locations from 631 respondents were analyzed. RESULTS: During the onset and peak of attacks, pain is concentrated periorbitally. Pain locations outside the periorbital region were reported more frequently for radiation than for onset and peak of attacks. Dorsal (occipital, neck, shoulder) pain was reported more frequently in connection with onset and radiation than during peak: onset (13%) versus peak (6%), p < 0.001, and radiation (22%) versus peak (6%), p < 0.001. There was no significant difference in dorsal pain frequencies for onset (13%) vs. radiation (22%), p = 0.552. Furthermore, the frequency with which individual pain locations were reported differed significantly for onset, peak, and radiation in CH. CONCLUSIONS: Analysis of the pain location data shows specific frequencies and distributions of pain location for three aspects of CH attacks. The frequency with which individual pain points were reported differed significantly for onset, peak, and radiation. In general, dorsal pain points were reported more frequently for onset and radiation than for peak pain. Pain locations beyond the eye (extraorbital points) were more frequently reported in connection with radiating pain. Our findings could serve as a basis for future research, correlating CH pain patterns with the outcome of treatment approaches.

A 4-year non-randomized comparative phase-IV study of early rheumatoid arthritis: integrative anthroposophic medicine for patients with preference against DMARDs versus conventional therapy including DMARDs for patients without preference.

BACKGROUND: While disease-modifying antirheumatic drugs (DMARDs) are a mainstay of therapy for rheumatoid arthritis (RA), some patients with early RA refuse DMARDs. In anthroposophic medicine (AM), a treatment strategy for early RA without DMARDs has been developed. Preliminary data suggest that RA symptoms and inflammatory markers can be reduced under AM, without DMARDs. PATIENTS AND METHODS: Two hundred and fifty-one self-selected patients aged 16-70 years, starting treatment for RA of <3 years duration, without prior DMARD therapy, participated in a prospective, non-randomized, comparative Phase IV study. C-patients were treated in clinics offering conventional therapy including DMARDs, while A-patients had chosen treatment in anthroposophic clinics, without DMARDs. Both groups received corticosteroids and nonsteroidal anti-inflammatory drugs (NSAIDs). Primary outcomes were intensity of RA symptoms measured by self-rating on visual analog scales, C-reactive protein, radiological progression, study withdrawals, serious adverse events (SAE), and adverse drug reactions in months 0-48. RESULTS: The groups were similar in most baseline characteristics, while A-patients had longer disease duration (mean 15.1 vs 10.8 months, p<0.0001), slightly more bone destruction, and a much higher proportion of women (94.6% vs 69.7%, p<0.0001). In months 0-12, corticosteroids were used by 45.7% and 81.6% (p<0.0001) and NSAIDs by 52.8% and 68.5% (p=0.0191) of A- and C-patients, respectively. During follow-up, both groups not only had marked reduction of RA symptoms and C-reactive protein, but also some radiological disease progression. Also, 6.2% of A-patients needed DMARDs. Apart from adverse drug reactions (50.4% and 69.7% of A- and C-patients, respectively, p=0.0020), none of the primary outcomes showed any significant between-group difference. CONCLUSION: Study results suggest that for most patients preferring anthroposophic treatment, satisfactory results can be achieved without use of DMARDs and with less use of corticosteroids and NSAIDs than in conventional care. LIMITATION: Because of the non-randomized study design, with A-patients choosing anthroposophic treatment, one cannot infer how this treatment would have worked for C-patients.

Early Monitoring of Response (MORE) to Golimumab Therapy Based on Fecal Calprotectin and Trough Serum Levels in Patients With Ulcerative Colitis: A Multicenter Prospective Study.

BACKGROUND: The treatment of ulcerative colitis (UC) patients with moderate to severe inflammatory activity with anti-tumor necrosis factor alpha (TNFα) antibodies leads to a clinical remission rate of 10% after 8 weeks of therapy. However, it must be taken into account that patient selection in clinical trials clearly influences both response and remission rates. An unsatisfactory response to anti-TNFα medication after week 12 often leads to a discontinuation of treatment. The early prediction of clinical response could therefore help optimize therapy and potentially avoid ineffective treatments. OBJECTIVE: The aim of this study is to develop an algorithm for optimizing golimumab administration in patients with moderate to severe UC by calculating the probability of clinical response in Week 26 based on data from Week 6. METHODS: The study is designed as a prospective, single-arm, multicenter, non-interventional observational study with no interim analyses and a sample size of 58 evaluable patients. The primary outcome is the prediction of clinical response in Week 26 based on a 50% reduction in fecal calprotectin and a positive golimumab trough level in Week 6. RESULTS: Enrollment started in October 2014 and was still open at the date of submission. The study is expected to finish in December 2016. CONCLUSIONS: The early identification of patients who are responding to an anti-TNFα antibody is therapeutically beneficial. At the same time, patients who are not responding can be identified earlier. The development of a therapeutic algorithm for identifying patients as responders or non-responders can thus help prescribing physicians to both avoid ineffective treatments and adjust dosages when necessary. This in turn promotes a higher degree of treatment tolerance and patient safety in the case of anti-TNFα antibody administration.

Anticoagulation with rivaroxaban for livedoid vasculopathy (RILIVA): a multicentre, single-arm, open-label, phase 2a, proof-of-concept trial.

BACKGROUND: Livedoid vasculopathy is a thrombotic skin disease characterised by recurrent occlusion of the cutaneous microcirculation in lower extremities, which results in skin infarctions with painful ulcerations and irreversible scar formation. Rivaroxaban is a direct factor Xa inhibitor that prevents thrombus formation. We investigated whether rivaroxaban is effective for the treatment of livedoid vasculopathy. METHODS: We did this single-arm, open-label, multicenter, phase 2a, proof-of concept trial at three university hospitals in Germany. Patients with livedoid vasculopathy and a minimum pain score of 40 on the visual analogue scale were eligible to participate. Patients received oral rivaroxaban tablets for 12 weeks at an initial dose of 10 mg twice per day, which was reduced to once per day if a reduction of pain by 50% on the visual analogue scale was achieved. Subcutaneous enoxaparin at 1 mg per kg bodyweight once or twice per day was allowed as a backup treatment in case of insufficient efficacy and increased pain. The primary endpoint was change in pain on the visual analogue scale from baseline to 12 weeks. Efficacy was assessed in the intention-to-treat population and safety was assessed in all patients who received at least one dose of study drug. This trial is registered with the EU Clinical Trials Register, EudraCT number 2012-000108-13-DE, and is closed to new participants. FINDINGS: Between Dec 28, 2012, and April 24, 2014, 36 patients were screened, 28 patients were recruited for the study, and 25 patients received treatment. During treatment, five patients dropped out of the study because of withdrawal of consent (one patient), lack of compliance (one patient), violation of inclusion criteria (two patients), and a serious adverse event (one patient). Median pain on the visual analogue scale decreased from 65·0 (IQR 52·0-78·0) at baseline to 6·0 (1·0-14·0) after 12 weeks of treatment (p<0·0001). Six of the 20 patients required additional treatment with enoxaparin. Eight treatment-related adverse events were recorded in six (24%) of the 25 patients: five cases of menorrhagia including one classified as both menorrhagia and dysmenorrhoea, one case of dyspnoea, and one case of gingival bleeding. The only serious adverse reaction to rivaroxaban during the study was one case of menorrhagia in a patient with concomitant endometriosis, which resulted in study discontinuation. INTERPRETATION: Rivaroxaban seems to effectively reduce pain in livedoid vasculopathy. Therefore we suggest that rivaroxaban with enoxaparin as a backup treatment is a suitable treatment option for patients with livedoid vasculopathy.

Azathioprine-induced Acute Pancreatitis in Patients with Inflammatory Bowel Diseases--A Prospective Study on Incidence and Severity.

BACKGROUND AND AIMS: Azathioprine [AZA] is recommended for maintenance of steroid-free remission in inflammatory bowel disease IBD. The aim of this study has been to establish the incidence and severity of AZA-induced pancreatitis, an idiosyncratic and major side effect, and to identify specific risk factors. METHODS: We studied 510 IBD patients [338 Crohn's disease, 157 ulcerative colitis, 15 indeterminate colitis] with initiation of AZA treatment in a prospective multicentre registry study. Acute pancreatitis was diagnosed in accordance with international guidelines. RESULTS: AZA was continued by 324 [63.5%] and stopped by 186 [36.5%] patients. The most common cause of discontinuation was nausea [12.2%]. AZA-induced pancreatitis occurred in 37 patients [7.3%]. Of these: 43% were hospitalised with a median inpatient time period of 5 days; 10% had peripancreatic fluid collections; 24% had vomiting; and 14% had fever. No patient had to undergo nonsurgical or surgical interventions. Smoking was the strongest risk factor for AZA-induced acute pancreatitis [p < 0.0002] in univariate and multivariate analyses. CONCLUSIONS: AZA-induced acute pancreatitis is a common adverse event in IBD patients, but in this study had a mild course in all patients. Smoking is the most important risk factor.

White-Light or Narrow-Band Imaging Colonoscopy in Surveillance of Ulcerative Colitis: A Prospective Multicenter Study.

BACKGROUND & AIMS: Early detection of neoplastic lesions is essential in patients with long-standing ulcerative colitis but the best technique of colonoscopy still is controversial. METHODS: We performed a prospective multicenter study in patients with long-standing ulcerative colitis. Two colonoscopies were performed in each patient within 3 weeks to 3 months. In white-light (WL) colonoscopy, stepwise random biopsy specimens (4 biopsy specimens every 10 cm), segmental random biopsies (2 biopsy specimens in 5 segments), and targeted biopsy specimens were taken. In NBI colonoscopy, segmental and targeted biopsy specimens were taken. The sequence of WL and NBI colonoscopy was randomized. RESULTS: In 36 of 159 patients enrolled (22.6%), 54 lesions with intraepithelial neoplasia (IN) were found (51 low-grade, 3 high-grade). In WL colonoscopy we found 11 IN in stepwise biopsy specimens, 4 in segmental biopsy specimens, and 15 in targeted biopsy specimens. In NBI colonoscopy 7 IN were detected in segmental biopsy specimens and 24 IN were detected in targeted biopsy specimens. Almost all IN were found with one technique alone (κ value of WL vs NBI, -0.86; P < .001). Statistically equivalent numbers of IN were found in NBI colonoscopy with targeted and segmental biopsy specimens as in WL colonoscopy with targeted and stepwise biopsy specimens, but with fewer biopsy specimens (11.9 vs 38.6 biopsy specimens, respectively; P < .001), and less withdrawal time was necessary (23 vs 13 min, respectively; P < .001). CONCLUSIONS: Stepwise biopsy specimens are indispensable in WL colonoscopy. The combination of targeted and segmental biopsy specimens in the NBI technique is as sensitive as targeted together with stepwise biopsy specimens in WL colonoscopy, but requires fewer biopsy specimens and less time. The highest sensitivity should be reached by combining the WL and NBI techniques by switching between the modes.

A Phase II Multicenter Trial With Rivaroxaban in the Treatment of Livedoid Vasculopathy Assessing Pain on a Visual Analog Scale.

BACKGROUND: Livedoid vasculopathy is an orphan skin disease characterized by recurrent thrombosis of the cutaneous microcirculation. It manifests itself almost exclusively in the ankles, the back of the feet, and the distal part of the lower legs. Because of the vascular occlusion, patients suffer from intense local ischemic pain. Incidence of livedoid vasculopathy is estimated to be around 1:100,000. There are currently no approved treatments for livedoid vasculopathy, making off-label therapy the only option. In Europe, thromboprophylactic treatment with low-molecular-weight heparins has become widely accepted. OBJECTIVE: The aim of this trial is the statistical verification of the therapeutic effects of the anticoagulant rivaroxaban in patients suffering from livedoid vasculopathy. METHODS: We performed a therapeutic phase IIa trial designed as a prospective, one-armed, multicenter, interventional series of cases with a calculated sample size of 20 patients. The primary outcome is the assessment of local pain on the visual analog scale (VAS) as an intraindividual difference of 2 values between baseline and 12 weeks. RESULTS: Enrollment started in December 2012 and was still open at the date of submission. The study is expected to finish in November 2014. CONCLUSIONS: Livedoid vasculopathy is associated with increased thrombophilia in the cutaneous microcirculation and the continuous use of anticoagulants helps improve the symptoms. The causes of cutaneous infarctions are heterogenous, but ultimately follow the known mechanisms of the coagulation cascade. Rivaroxaban affects the coagulation cascade and inhibits the factor Xa-dependent conversion of prothrombin to thrombin, thereby considerably reducing the risk of thrombosis.

German Randomized Acupuncture Trial for chronic shoulder pain (GRASP) - a pragmatic, controlled, patient-blinded, multi-centre trial in an outpatient care environment.

UNLABELLED: The German Randomized Acupuncture Trial for chronic shoulder pain (GRASP) comprised 424 outpatients with chronic shoulder pain (CSP) > or =6 weeks and an average pain score of VAS > or =50 mm, who were randomly assigned to receive Chinese acupuncture (verum), sham acupuncture (sham) or conventional conservative orthopaedic treatment (COT). The patients were blinded to the type of acupuncture and treated by 31 office-based orthopaedists trained in acupuncture; all received 15 treatments over 6 weeks. The 50% responder rate for pain was measured on a VAS 3 months after the end of treatment (primary endpoint) and directly after the end of the treatment (secondary endpoint). RESULTS: In the ITT (n=424) analysis, percentages of responders for the primary endpoint were verum 65% (95% CI 56-74%) (n=100), sham 24% (95% CI 9-39%) (n=32), and COT 37% (95% CI 24-50%) (n=50); secondary endpoint: verum 68% (95% CI 58-77%) (n=92), sham 40% (95% CI 27-53%) (n=53), and COT 28% (95% CI 14-42%) (n=38). The results are significant for verum over sham and verum over COT (p<0.01) for both the primary and secondary endpoints. The PPP analysis of the primary (n=308) and secondary endpoints (n=360) yields similar responder results for verum over sham and verum over COT (p<0.01). Descriptive statistics showed greater improvement of shoulder mobility (abduction and arm-above-head test) for the verum group versus the control group immediately after treatment and after 3 months. The trial indicates that Chinese acupuncture is an effective alternative to conventional orthopaedic treatment for CSP.

Correlation between severity of disease and reimbursement of costs in neonatal and paediatric intensive care patients.

AIM: The aim of the present study was to investigate the correlation between neonatal, paediatric and adult disease severity scores and reimbursement by health insurances. METHODS: The setting was a university hospital's neonatal intensive care unit (NICU) and paediatric intensive care unit (PICU). We performed a prospective study of all patients admitted over the 3-month study period. Data collected included five scoring systems to predict mortality or to quantify disease severity (Paediatric Index of Mortality [PIM], Paediatric Risk of Mortality [PRISM], Simplified Acute Physiological Score [SAPS], Score for Neonatal Acute Physiology [SNAP], Therapeutic Intervention Scoring System [TISS]) on a daily basis, the total reimbursement as calculated by the grouper according to the German diagnosis-related groups (DRG) system, age of the patient, length of stay (LOS), International Classification of Diseases (ICD)-10 and DRG diagnosis. Our intention was to determine the correlation between different neonatal, paediatric and adult scores (PIM, PRISM III, SAPS-II, SNAP, Core-10-TISS), and reimbursement by the health insurance on the basis of the German DRG system in its 2005 and 2007 version. RESULTS: No positive correlation between any score applied and reimbursement by the health insurance could be identified. Reimbursement was positively correlated to the length of hospital stay. Positive correlations could also be shown for some of the scores among each other. CONCLUSION: We conclude that other scoring systems or measures of disease severity urgently need to be established to terminate the chronic underfunding of paediatric intensive care medicine in the developed countries.
