RESUMO

BACKGROUND: Travel to regions with rabies risk has increased. However, data on adequate rabies post exposure prophylaxis (PEP) abroad is scarce. The aim of this study was to assess the appropriateness of medical management following suspected rabies exposure (SRE) in international travellers. METHOD: A cross-sectional questionnaire-based study in returning travellers with reported SRE who sought post-exposure medical care was conducted in two large German travel clinics. RESULTS: The 75 included SRE cases had a median age of 34 years (range 26-43) and showed a female predominance (59%, 44/75). Most participants returned from Asia (47%, 34/72). About 28% had received pre-exposure prophylaxis (PrEP, ≥2 vaccine doses) (20/71). In 51% the animal was actively approached (34/67). All patients had category II/III exposure according to the World Health Organization (65% category III, 49/75). With 78% (52/67), most patients cleaned the wound after SRE; 36% (24/67) used water and soap. Only 57% (41/72) of participants sought medical care during their trip. Overall, 45% (33/74) received rabies vaccination abroad which corresponds to 80% out of those who sought healthcare (33/41). CONCLUSIONS: Awareness for appropriate first aid and the urgency of seeking timely professional treatment including PEP after an SRE seems to be insufficient in German travellers. Travel practitioners need to educate travellers about rabies risk, prevention measures and the correct behaviour after SRE including adequate wound treatment and seeking immediate medical help for PEP. PrEP should be offered generously especially to travellers with high rabies-exposure risk and those visiting areas with limited healthcare access.

RESUMO

Background: Coagulopathy is common in acute symptomatic Plasmodium falciparum malaria, and the degree of coagulation abnormality correlates with parasitemia and disease severity. Chronic asymptomatic malaria has been associated with increased morbidity. However, the role of coagulation activation in asymptomatic, semi-immune individuals remains unclear. This study investigates the potential effect of asymptomatic P falciparum infection on coagulation activation in semi-immune Ghanaian adults. Methods: Blood from asymptomatic Ghanaian adults with P falciparum blood stage infection detectable by polymerase chain reaction (PCR) or by both PCR and rapid diagnostic test and from noninfected individuals, was investigated. Markers of coagulation activation including global coagulation tests, D-dimer, antithrombin III, fibrinogen, and von Willebrand factor antigen were tested. Furthermore, blood count, inflammation markers, and liver and kidney function tests were assessed. Results: Acquired coagulopathy was not found in asymptomatic P falciparum infection. Asymptomatic malaria was associated with significantly lower platelet counts. Systemic inflammation markers and liver and kidney function tests were not altered compared to noninfected controls. Conclusions: There is no laboratory evidence for acquired coagulopathy in adults with asymptomatic P falciparum malaria in highly endemic regions. Lack of laboratory evidence for systemic inflammation and liver and kidney dysfunction indicates that asymptomatic malaria may not be associated with significant morbidity.

RESUMO

Unlike other nucleotide oligomerization domain-like receptors, Nlrp10 lacks a canonical leucine-rich repeat domain, suggesting that it is incapable of signal sensing and inflammasome formation. Here we show that mouse Nlrp10 is expressed in distal colonic intestinal epithelial cells (IECs) and modulated by the intestinal microbiome. In vitro, Nlrp10 forms an Apoptosis-associated speck-like protein containing a caspase-recruitment domain (ASC)-dependent, m-3M3FBS-activated, polyinosinic:polycytidylic acid-modulated inflammasome driving interleukin-1ß and interleukin-18 secretion. In vivo, Nlrp10 signaling is dispensable during steady state but becomes functional during autoinflammation in antagonizing mucosal damage. Importantly, whole-body or conditional IEC Nlrp10 depletion leads to reduced IEC caspase-1 activation, coupled with enhanced susceptibility to dextran sodium sulfate-induced colitis, mediated by altered inflammatory and healing programs. Collectively, understanding Nlrp10 inflammasome-dependent and independent activity, regulation and possible human relevance might facilitate the development of new innate immune anti-inflammatory interventions.

RESUMO

BACKGROUND: Primary sclerosing cholangitis (PSC) is a progressive bile duct disease associated with inflammatory bowel disease (PSC-IBD). AIM: To investigate whether patients with PSC-IBD benefit from a gluten-free and amylase trypsin inhibitor (ATI)-free diet (GFD). METHODS: We performed a prospective clinical pilot study administering an eight-week GFD. The primary outcomes were colonic inflammation assessed by proctosigmoidoscopy, and liver stiffness (surrogate for fibrosis, inflammation and cholestasis) measured by transient elastography before and after GFD. Amongst the secondary (exploratory) outcomes were colonic mucosal and serum cytokine/chemokine changes, the intestinal microbiome and transcriptome dynamics, and shifts in serum markers of hepatic fibrogenesis. RESULTS: Fifteen patients with PSC-IBD completed the study. The study did not meet its primary outcome: the endoscopic score and liver stiffness remained unchanged. However, the expression of pro-inflammatory mucosal cytokines and chemokines such as IL6, IL8, CCL2, and TNFα was significantly down-regulated. Two critical markers of liver fibrosis and matrix remodelling, thrombospondin-2 and -4, decreased significantly. The microbiota composition changed slightly, including a decrease in the pathogen Romboutsia ilealis. The intestinal transcriptome indicated a gut barrier improvement. Pruritus, fatigue, overall well-being, faecal calprotectin levels, and serum alkaline phosphatase did not change significantly. CONCLUSIONS: This study did not demonstrate a clinical improvement with short-term GFD in patients with PSC-IBD. However, a gluten/ATI-free diet may improve biomarkers of intestinal inflammation and barrier function in these patients with associated changes in the enteric microbiota. Further investigation of the therapeutic potential of the GFD in PSC-IBD is warranted.

RESUMO

OBJECTIVES: The global prevalence of intestinal extended-spectrum ß-lactamase-producing Enterobacterales (ESBL-PE) is approximately 17% in communities, with significant variations among regions. This longitudinal study aimed to assess the impact of antibiotic intake on the incidence of intestinal ESBL-PE in Ghanaian pharmacy customers outside of hospitals. METHODS: Screening for ESBL-PE was performed in four independent pharmacies in Kumasi, Ghana, using rectal swabs and an ESBL-PE-selective medium. Pharmacy customers purchasing antibiotics were recruited, and those buying non-antibiotic drugs served as controls. Participants who were negative for ESBL-PE provided follow-up swabs for up to 28 days. RESULTS: At baseline, 302 (75%) of 404 participants were colonized with ESBL-PE. Sixty-three participants who were negative for ESBL-PE at baseline received per-protocol follow-up, including 28 individuals who took antibiotics and 35 controls. The cumulative proportions of ESBL-PE in the antibiotics and control groups were 71% (20/28) and 54% (19/35) at the first follow-up (p 0.258), 86% (24/28) and 80% (28/35) at the second follow-up (p 0.741) and 86% (24/28) and 94% (33/35) at the third follow-up (p 0.393), respectively. DISCUSSION: The rate of intestinal ESBL-PE carriage among pharmacy customers outside of hospitals was higher than expected at baseline and further increased during the 28 days of follow-up, irrespective of antibiotic intake. This alarming finding needs to be considered in the antibiotic treatment of outpatients and emphasizes the urgent need for improved prevention strategies, development of new antibiotic drugs and potential future elimination strategies. Further longitudinal studies on ESBL-PE in African communities, also outside of pharmacy settings, are required.

RESUMO

Non-nutritive sweeteners (NNS) are commonly integrated into human diet and presumed to be inert; however, animal studies suggest that they may impact the microbiome and downstream glycemic responses. We causally assessed NNS impacts in humans and their microbiomes in a randomized-controlled trial encompassing 120 healthy adults, administered saccharin, sucralose, aspartame, and stevia sachets for 2 weeks in doses lower than the acceptable daily intake, compared with controls receiving sachet-contained vehicle glucose or no supplement. As groups, each administered NNS distinctly altered stool and oral microbiome and plasma metabolome, whereas saccharin and sucralose significantly impaired glycemic responses. Importantly, gnotobiotic mice conventionalized with microbiomes from multiple top and bottom responders of each of the four NNS-supplemented groups featured glycemic responses largely reflecting those noted in respective human donors, which were preempted by distinct microbial signals, as exemplified by sucralose. Collectively, human NNS consumption may induce person-specific, microbiome-dependent glycemic alterations, necessitating future assessment of clinical implications.

RESUMO

Autoimmune liver diseases are a group of immune-mediated liver diseases with three distinct entities, including autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis. The interplay of genetic and environmental factors leads to the breakdown of self-tolerance, resulting in hyper-responsiveness, and auto-aggressive immune activation. Emerging evidence links autoimmune liver diseases with alterations of the commensal microbiome configuration and aberrant immune system activation by microbial signals, mainly via the gut-liver axis. Thus, the microbiome is a new frontier to deepen the pathogenetic understanding, uncover biomarkers, and inspire innovative treatments. Herein, we review the current evidence on the role of the microbiome in autoimmune liver diseases from both clinical and basic research. We highlight recent achievements and also bottlenecks and limitations. Moreover, we give an outlook on future developments and potential for clinical applications.

RESUMO

Knowledge of living donor liver transplantation (LDLT) for autoimmune liver diseases (AILDs) is scarce. This study analyzed survival in LDLT recipients registered in the European Liver Transplant Registry with autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis (PSC) and the non-autoimmune disorder alcohol-related cirrhosis. In total, 29 902 individuals enrolled between 1998 and 2017 were analyzed, including 1003 with LDLT. Survival from >90 days after LDLT for AILDs in adults was 85.5%, 74.2%, and 58.0% after 5, 10, and 15 years. Adjusted for recipient age, sex, and liver transplantation era, adult PSC patients receiving LDLT showed increased mortality compared to donation after brain death (DBD) (hazard ratio [HR] = 1.95, 95% confidence interval [CI] = 1.36-2.80, p < .001). Pediatric PSC patients showed also increased mortality >90 days after LDLT compared to DBD (HR = 3.00, 95% CI 1.04-8.70, p = .043). Multivariate analysis identified several risk factors for death in adult PSC patients receiving LDLT including a male donor (HR = 2.49, p = .025). Adult PSC patients with LDLT versus DBD conferred increased mortality from disease recurrence (subdistribution hazard ratio [subHR] = 5.36, p = .001) and biliary complications (subHR = 4.40, p = .006) in multivariate analysis. While long-term outcome following LDLT for AILD is generally favorable, PSC patients with LDLT compared to DBD might be at increased risk of death.

RESUMO

OBJECTIVES: This longitudinal case-control study aimed to determine the frequency of polymicrobial enteric detections in Ghanaian infants with and without diarrhoea. METHODS: Infants aged 1-12 months with and without diarrhoea attending the outpatient department of a peri-urban Ghanaian hospital were prospectively assessed and stool samples were collected on days 0, 6 and 28 and analysed for 18 enteric pathogens with PCR. RESULTS: At least one enteric pathogen was detected in 100 of 107 cases with diarrhoea (93%) and in 82 of 97 controls (85%). The number of pathogens was higher in cases than in controls (median three versus two pathogens, p 0.001). The adjusted attributable fraction (AF) for diarrhoea was highest for enterotoxigenic Escherichia coli (7.2%, 95% CI -2.0% to 16.3%), rotavirus (4.1%, 95% CI 0.6%-7.5%), Giardia lamblia (2.3%, 95% CI -0.7 to 5.3%) and astrovirus (2.3%, 95% CI -2.9 to 7.5%). In cases, a higher pathogen number was significantly associated with watery stool consistency (median 3, interquartile range (IQR) 2-5 versus median 2.5, IQR 1-4, p 0.014), stool frequency five or more per day (median 4, IQR 3-5 versus median 3, IQR 2-4, p 0.048) and vomiting (median 4, IQR 3-5 versus median 3, IQR 2-4, p 0.025). During follow-up, 94% (78/83) of cases and 85% (67/79) of controls had acquired at least one new pathogen without developing a new episode of diarrhoea. CONCLUSION: Enteric pathogens could be identified in the stool of the vast majority of Ghanaian infants, whereby pathogens were very frequently acquired without resulting in new episodes of diarrhoea during follow-up. A higher number of co-occurring pathogens may increase the risk of diarrhoea and disease severity.

RESUMO

OBJECTIVES: To provide a basis for clinical management decisions in Paecilomyces variotii infection. METHODS: Unpublished cases of invasive P. variotii infection from the FungiScope® registry and all cases reported in the literature were analysed. RESULTS: We identified 59 cases with P. variotii infection. Main baseline factors were presence of indwelling devices in 29 cases (49.2%), particularly peritoneal catheters (33.9%) and prosthetic heart valves (10.2%), haematological or oncological diseases in 19 (32.2%), major surgery in 11 (18.6%), and diabetes mellitus in 10 cases (16.9%). The most prevalent infection sites were peritoneum (n = 20, 33.3%) and lungs (n = 16, 27.1%). Pain and fever were frequent (n = 35, 59.3% and n = 33, 55.9%, respectively). Diagnosis was established by culture in 58 cases (98.3%). P. variotii caused breakthrough infection in 8 patients. Systemic antifungals were given in 52 patients (88.1%). Amphotericin B was administered in 39, itraconazole in 15, and posaconazole in 8 patients. Clinical isolates were frequently resistant to voriconazole, whereas the above-mentioned antifungals showed good in vitro activity. Infections of the blood and CNS caused high mortality. Overall mortality was 28.8% and death was attributed to P. variotii in 10 cases. CONCLUSIONS: P. variotii causes life-threatening infections, especially in immunocompromised and critically ill patients with indwelling devices. Patients undergoing peritoneal dialysis are at particular risk. Multidisciplinary management is paramount, including molecular techniques for diagnosis and treatment with efficacious systemic antifungals. Amphotericin B, itraconazole and posaconazole are regarded as treatments of choice. Combination with flucytosine may be considered. Surgical debridement and removal of indwelling devices facilitate favourable outcome.

RESUMO

BACKGROUND: While the prognosis of patients with Ewing sarcoma (EwS) is improving, little is known about the frequency of pain and its risk factors in survivors of EwS. This study aims to analyse the prevalence and risk factors of pain and its predictive value for recurrence. PATIENTS AND METHODS: In patients with remission after treatment of EwS, frequency and characteristics of pain within the first 5 years of follow up were assessed retrospectively. RESULTS: Of 80 patients, 37 (46%) presented with at least one episode of pain. Chronic pain (>3 months) was observed in 10 patients (13%). Experience of at least one episode of pain was associated with prior combined local treatment (surgery and radiation compared to surgery alone; odds ratio [OR] 5.83, 95% confidence interval [CI] 1.43-34.9, P = .007). A total of 59 episodes of pain were observed, including 47 acute and 12 chronic episodes. Lower limb pain accounted for 46% (27/59) of all episodes of pain, and was associated with primary tumour of the pelvis or lower extremity (OR 4.29, 95% CI 1.18-18.21, P = .025), which represented 64% (51/80) of all EwS. The positive predictive value of pain for recurrence was only 12%. CONCLUSION: Pain is a common problem in survivors of EwS, which mostly affects the lower extremity, and should be regularly assessed. Interventions to reduce pain may be particularly important in patients with combined local treatment with surgery and radiation, who seem to be at considerably increased risk for pain. Patients presenting with pain should be examined for recurrence.

RESUMO

BACKGROUND: Ghana is among the high-burden countries for malaria infections and recently reported a notable increase in malaria cases. While asymptomatic parasitaemia is increasingly recognized as a hurdle for malaria elimination, studies on asymptomatic malaria are scarce, and usually focus on children and on non-falciparum species. The present study aims to assess the prevalence of asymptomatic Plasmodium falciparum and non-falciparum infections in Ghanaian adults in the Ashanti region during the high transmission season. METHODS: Asymptomatic adult residents from five villages in the Ashanti Region, Ghana, were screened for Plasmodium species by rapid diagnostic test (RDT) and polymerase chain reaction (PCR) during the rainy season. Samples tested positive were subtyped using species-specific real-time PCR. For all Plasmodium ovale infections additional sub-species identification was performed. RESULTS: Molecular prevalence of asymptomatic Plasmodium infection was 284/391 (73%); only 126 (32%) infections were detected by RDT. While 266 (68%) participants were infected with Plasmodium falciparum, 33 (8%) were infected with Plasmodium malariae and 34 (9%) with P. ovale. The sub-species P. ovale curtisi and P. ovale wallikeri were identified to similar proportions. Non-falciparum infections usually presented as mixed infections with P. falciparum. CONCLUSIONS: Most adult residents in the Ghanaian forest zone are asymptomatic Plasmodium carriers. The high Plasmodium prevalence not detected by RDT in adults highlights that malaria eradication efforts must target all members of the population. Beneath Plasmodium falciparum, screening and treatment must also include infections with P. malariae, P. o. curtisi and P. o. wallikeri.

RESUMO

Ocular complications are rare in patients with dengue fever, but may cause permanent loss of vision. We present the case of a 29-year-old German woman who developed severe acute vision loss because of dengue-associated maculopathy after traveling to Vietnam and Cambodia. Initially, the optical coherence tomography showed detachment of the retinal pigment epithelium, a central shift in the retinal pigmentation and intraretinal cysts. The patient was hospitalized and treated with a short course of intravenous prednisolone. Vision improved, and the patient showed full recovery at 9 months after the onset. This case highlights the importance of awareness and adequate management for ocular involvement in patients with dengue fever, including travelers.

RESUMO

Leishmaniasis is a protozoan parasitic infection that can manifest as visceral or cutaneous disease. Immunosuppression, mainly through TNF-α) inhibition, is a risk factor for complicated leishmaniasis that is becoming increasingly known. Here, we present a case of cutaneous leishmaniasis (CL) in a patient who suffers from advanced Takayasu-Arteritis, requiring TNF-α inhibition with infliximab. The primary CL lesions in this 47-year-old, female patient were caused by Leishmaniapanamensis and occurred after a touristic trip to Panama on her right foot. The lesions first resolved under treatment with liposomal amphotericin B. However, ten months later, the patient returned with relapsing lesions requiring further treatment. We discuss the challenges and risks of leishmaniasis in patients with TNF-α inhibition and the rare phenomenon of relapsing CL and the management hereof. We review published cases of CL associated with TNF-α inhibition. A growing body of evidence now suggests that especially CL (and visceral leishmaniasis (VL)) can be associated with TNF-α inhibition. The host response to leishmaniasis is of the Th1-type and TNF-α and interferon-gamma expression are crucial for disease control. Inversely, TNF-α inhibition can lead to complicated and relapsing progression of leishmanial infection. Therefore, we propose that CL and VL should be considered in at-risk patients receiving immunosuppressants.

RESUMO

The aim of this study was to analyze longterm patient and graft survival after liver transplantation for autoimmune hepatitis (AIH-LT) from the prospective multicenter European Liver Transplant Registry. Patient and liver graft survival between 1998 and 2017 were analyzed. Patients after AIH-LT (n = 2515) were compared with patients receiving LT for primary biliary cholangitis (PBC-LT; n = 3733), primary sclerosing cholangitis (PSC-LT; n = 5155), and alcohol-related cirrhosis (AC-LT; n = 19,567). After AIH-LT, patient survival was 79.4%, 70.8%, and 60.3% and graft survival was 73.2%, 63.4%, and 50.9% after 5, 10, and 15 years of follow-up. Overall patient survival was similar to patients after AC-LT (P = 0.44), but worse than after PBC-LT (hazard ratio [HR], 1.48; P < 0.001) and PSC-LT (HR, 1.19; P = 0.002). AIH-LT patients were at increased risk for death (HR, 1.37-1.84; P < 0.001) and graft loss (HR, 1.35-1.80; P < 0.001) from infections compared with all other groups and had a particularly increased risk for lethal fungal infections (HR, 3.38-4.20; P ≤ 0.004). Excluding patients who died within 90 days after LT, risk of death after AIH-LT was superior compared with AC-LT (HR, 0.84; P = 0.004), worse compared with PBC-LT (HR, 1.38; P < 0.001) and similar compared with PSC-LT (P = 0.93). Autoimmune hepatitis (AIH) patients with living donor liver transplantation (LDLT) showed reduced survival compared with patients receiving donation after brain death (HR, 1.96; P < 0.001). In AIH-LT patients, overall survival is inferior to PBC-LT and PSC-LT. The high risk of death after AIH-LT is caused mainly by early fatal infections, including fungal infections. Patients with LDLT for AIH show reduced survival.

RESUMO

OBJECTIVES: Invasive fungal infections caused by Lomentospora prolificans are associated with very high mortality rates and can be challenging to treat given pan-drug resistance to available antifungal agents. The objective of this study was to describe the clinical presentation and outcomes in a cohort of patients with invasive L prolificans infections. METHODS: We performed a retrospective review of medical records of patients with invasive L prolificans infection in the FungiScope® registry of rare invasive fungal infections. Patients diagnosed between 01 January 2008 and 09 September 2019 were included in for analysis. RESULTS: The analysis included 41 patients with invasive L prolificans infection from eight different countries. Haematological/oncological malignancies were the most frequent underlying disease (66%), disseminated infection was frequent (61%), and the lung was the most commonly involved organ (44%). Most infections (59%) were breakthrough infections. Progression/deterioration/treatment failure was observed in 23/40 (58%) of patients receiving antifungal therapy. In total, 21/41 (51%) patients, and 77% of patients with underlying haematological/oncological malignancy, had a fatal outcome attributed to invasive fungal infection. Combination antifungal therapy was frequent (24/40) and associated with improved survival. In particular, treatment regimens including terbinafine were significantly associated with higher treatment success at final assessment (P = .012), with a positive trend observed for treatment regimens that included voriconazole (P = .054). CONCLUSIONS: Lomentospora prolificans infections were associated with mortality rates of 77% and above in patients with underlying haematological/oncological malignancies and those with disseminated infections. While combination therapy is the preferred option for now, the hope lies with novel antifungals currently under development.

RESUMO

BACKGROUND & AIMS: Biliary strictures are common complications after orthotopic liver transplantation. Endoscopic retrograde cholangiography evolved as standard and percutaneous transhepatic cholangiodrainage as alternative therapy. This study analysed predictors of long-term success of biliary strictures after endoscopic retrograde cholangiography and/or percutaneous transhepatic cholangiodrainage and its impact on patient survival. METHODS: All adult patients with biliary strictures receiving endoscopic retrograde cholangiography and/or percutaneous transhepatic cholangiodrainage between 2009 and 2015 at the University Medical Center Hamburg-Eppendorf were retrospectively analysed. Potential predictors of long-term success (≥12 months) were identified by univariate and logistic regression analyses. Patient survival was analysed by Kaplan-Meier method and log-rank test. RESULTS: Hundred and sixteen patients were treated with endoscopic retrograde cholangiography and/or percutaneous transhepatic cholangiodrainage, including 67 patients with anastomotic strictures, 22 with nonanastomotic strictures and 27 with both stricture types. Eighty-five patients received endoscopic retrograde cholangiography, 17 percutaneous transhepatic cholangiodrainage and 14 both techniques. Long-term success was achieved in 60 patients (52%). Predictors of treatment failure were a preinterventional C-reactive protein >8 g/dL in anastomotic strictures (P = 0.039) and a body mass index ≤21 kg/m2 in nonanastomotic strictures (P = 0.021). In patients who received endoscopic retrograde cholangiography only, balloon dilatation of anastomotic strictures with larger diameters favoured success (P = 0.015). Achievement of long-term success was associated with prolonged patient survival in anastomotic strictures (P = 0.036) and nonanastomotic strictures (P = 0.025), but not in combined strictures (P = 0.739). CONCLUSION: In post-orthotopic liver transplantation biliary strictures treated by endoscopic retrograde cholangiography and/or percutaneous transhepatic cholangiodrainage, patient BMI and preinterventional C-reactive protein may influence prognosis. Endoscopic retrograde cholangiography with larger balloon diameter may favour success in anastomotic strictures. Long-term success by endoscopic retrograde cholangiography and/or percutaneous transhepatic cholangiodrainage is associated with superior survival in patients with anastomotic strictures and nonanastomotic strictures only.

RESUMO

BACKGROUND: The Interdisciplinary Tumor Board (ITB) of the Cooperative Ewing Sarcoma Study (CESS) Group was investigated to assess its impact on the overall survival (OAS) of Ewing sarcoma (EwS) patients. The ITB functions as a reference center for the international institutions participating in the clinical trials of the CESS group, but is also available internationally to patients who have not been treated within an appropriate clinical trial. The value of tumor boards in terms of benefit for the patients and the health care system in general is not well documented and is also the subject of controversial discussions. A review of the representative literature is included. METHODS: Data were analyzed from 481 patients who had been registered into the European Ewing Tumor Working Initiative of National Groups (EURO E.W.I.N.G.-99) clinical trial via the CESS data center between 2006 and 2009; this included 331 patients with localized disease and another 150 individuals with metastases at diagnosis. Median follow-up time was 3.2 years. RESULTS: Improved OAS was observed for patients with metastases who had received recommendations from the ITB compared with those who had not received recommendations. In patients with localized disease, a recommendation from the ITB had no influence on OAS. CONCLUSION: As a reference center for a rare disease, recommendations from our ITB impacted local therapy and led to higher OAS in patients with metastatic disease. To our knowledge, this is the first analysis that examines the value of a reference tumor board on a rare disease.

RESUMO

BACKGROUND: The Cooperative Ewing Sarcoma Study and the Late Effects Surveillance System of the Society for Paediatric Oncology and Haematology recommend a structured follow-up imaging protocol (FUIP) for patients with Ewing sarcoma (EwS) with decreasing frequency of imaging over the first 5 years. The present study aims to assess the effectiveness of the FUIP for EwS patients regarding survival after relapse. PATIENTS AND METHODS: A retrospective multicenter analysis on 160 eligible patients with EwS recurrence was performed. Potential survival differences following recurrence diagnosis between patients with protocol-detected and symptomatic relapse were investigated using the Kaplan-Meier method. Additional subgroup analyses were performed on the relapse type. Overall survival (OS) was calculated from diagnosis of relapse to last follow-up or death. RESULTS: In the multicenter analysis, recurrence was detected by FUIP in 77 of 160 patients (48%) and due to symptoms in 83 patients (52%). Regarding the entire study population, OS was significantly superior in patients with protocol-detected relapse compared to patients with symptomatic relapse (median, 2.4 vs. 1.2 years; P < 0.001). In the subgroup analyses, patients whose lung recurrences were detected by the FUIP experienced longer survival after recurrence than those whose recurrences were detected symptomatically (P = 0.023). In the 83 symptomatic patients, pain was the most prevalent symptom of relapse (72%). CONCLUSION: FUIP may benefit survival in EwS relapse, especially in lung recurrence. Pain was the leading symptom of relapse.
