Weight-Loss Endoscopy Trial: A Multicenter, Randomized, Controlled Trial Comparing Weight Loss in Endoscopically Implanted Duodenal-Jejunal Bypass Liners versus Intragastric Balloons versus a Sham Procedure.

INTRODUCTION: Obesity is associated with reduced life expectancy and various comorbidities. Surgical interventions are effective but accompanied by the risk of serious complications. Less invasive endoscopic procedures mainly comprise the intragastric balloon (IB) and the duodenal-jejunal bypass liner (DJBL). A randomized, sham-controlled study comparing both procedures has not been undertaken so far. METHODS: We performed a randomized, patient- and assessor-blinded, controlled trial comparing weight loss in IB versus DJBL versus a sham procedure (2:2:1 ratio). Patients with a BMI >35 kg/m2 or >30 with obesity-related comorbidities were included. The IB was removed after 6 months and the DJBL after 12 months. The main objective was successful weight loss (>10% from baseline) 12 months after explantation of the devices. Secondary outcomes were changes in comorbidities, quality of life, and complications. RESULTS: Thirty-three patients were randomized. Recruitment has to be stopped suddenly in after the DJBL device lost its CE mark in Europe. In all, 11 patients received DJBL, 15 IB, and 7 were allocated to the sham group. Blinding was feasible in all patients. Weight decreased from baseline until explantation (DJBL: 129.4 ± 28.3 kg to 107.4 ± 16.7 kg; IB: 118.3 ± 22.8 kg to 107.4 ± 25.7 kg; sham: 134.6 ± 18.0 kg to 131.2 ± 14.3 kg), but patients regained weight almost to the baseline level 12 months after explantation. Only 1 patient in IB group reached the primary endpoint. Severe device-related complications were very rare. CONCLUSION: Endoscopic bariatric procedures failed to achieve effective weight loss 12 months after explantation of the devices. The results of this trial need to be interpreted with caution due to its early termination.

[Management of gastroparesis care in Germany - a survey by the working group of guiding gastroenterologic clinicians (Arbeitsgemeinschaft Leitender Gastroenterologischer Krankenhausärzte, ALGK)]. / Versorgungsrealität der Gastroparese in Deutschland ­ eine Umfrage der Arbeitsgemeinschaft Leitender Gastroenterologischer Krankenhausärzte (ALGK).

INTRODUCTION: The treatment of gastroparesis can be difficult in everyday clinical practice. The aim of this anonymous survey of members of the Arbeitsgemeinschaft Leitender Gastroenterologischer Krankenhausärzte e.V. (ALGK) was to investigate the management of gastroparesis care in Germany. MATERIAL AND METHODS: The ALGK conducted a member survey using a standardized anonymous questionnaire including 11 questions from 14.04.2023 to 29.04.2023. The questions covered diagnostic and therapeutic procedures as well as various aspects of the management of gastroparesis. RESULTS: The response rate was 21.4% (62 members). Only 6.56% of all respondents assessed the prevalence of gastroparesis correctly as estimated by current epidemiological publications. 68.85 % of all respondents used gastric emptying scintigraphy for diagnosis. 51.61% regarded an individualized therapy as the most important treatment goal, taking into account etiology and impact of symptoms, compared to symptomatic treatment of leading clinical symptom in 43,55 %. First choice treatment was medical treatment in 41.94%, dietary recommendations in 27.42% and endoscopic interventions in 24.2%. 100% of respondents used prokinetics, 40.32% used antiemetics while only 4.84% used analgesics. Insufficient availability of medical treatment options represents a need of action for 85.48%, compared to lacking official approval of available drugs for this indication for 48,39% of all respondents. Treatment options with little evidence were used quite frequently (e.g. use of herbal therapies in 43.55%). DISCUSSION: Overall, the frequency of gastroparesis was underestimated in the current survey. Endoscopic options are quite often used as first-line treatment. Although symptom-guided treatment is important for the majority of respondents, prokinetics are predominantly used.

[Takayasu arteritis after COVID-19 infection in a 26-year-old female patient with Crohn's disease]. / Takayasu ­ Arteriitis nach COVID-19-Infektion bei einer 26 Jahre alten Patientin mit Morbus Crohn.

Extraintestinal manifestations, e.g. of the skin, joints or liver, are frequently found in Crohn's disease. We report about a 26-year-old female patient with longstanding Crohn's disease, who was admitted to our hospital with suspicion of an acute attack with suggestive symptoms and increased significantly inflammatory parameters. Shortly before, symptomatic COVID-19 disease (SARS-CoV-2 variant omicron) had been made. Comprehensive endoscopic and imaging diagnostics ruled out active Crohn's disease. However, inflammatory thickening of the aortic arch was seen, and a diagnosis of Takayasu arteritis (type II b) was made. Steroid therapy resulted in a rapid and sustained improvement of clinical symptoms. The occurrence of Takayasu arteritis is extremely rare outside Japan. An coincidence has been described in chronic inflammatory bowel diseases and is discussed as a possible extraintestinal manifestation. The occurrence of immune-mediated disease after COVID-19 disease has been described and may be triggered by the infection. Patients with inflammatory bowel disease may represent a special risk population.

[Costs of potentially outpatient endoscopic procedures in cases with a 1-day hospital stay versus a longer stay]. / Kosten potenziell ambulant erbringbarer endoskopischer Leistungen in Fällen mit 1-Tages-Verweildauer gegenüber einer längeren Verweildauer.

INTRODUCTION: The transfer of patient care and medical interventions that was previously provided on an inpatient basis to outpatient settings is a stated goal of health politics. It is unclear to what extent costs of an endoscopic procedure and the disease severity depend on the duration of inpatient treatment. We therefore examined whether endoscopic services for cases with a one-day length of stay (VWD) are comparably expensive to cases with a longer VWD. METHODS: Outpatient services were selected from the DGVS service catalog. Day cases with exactly one such gastroenterological endoscopic (GAEN) service were compared with cases with VWD>1 day regarding their patient clinical complexity levels (PCCL) and mean costs. Data from the DGVS-DRG project with §21-KHEntgG cost data from a total of 57 hospitals from 2018 and 2019 served as the basis. Endoscopic costs were taken from cost center group 8 of the InEK cost matrix and plausibility checked. RESULTS: A total of 122,514 cases with exactly one GAEN service were identified. Statistically equal costs were shown in 30 of 47 service groups. In 10 groups, the cost difference was not relevant (<10%). Cost differences >10% existed only for EGD with variceal therapy, insertion of a self-expanding prosthesis, dilatation/bougienage/exchange with PTC/PTCD in place, non-extensive ERCP, endoscopic ultrasound in the upper gastrointestinal tract, and colonoscopy with submucosal or full thickness resection, or foreign object removal. PCCL differed in all but one group. CONCLUSION: Gastroenterology endoscopy services provided as part of inpatient care but potentially performable on an outpatient basis are predominantly equally expensive for day cases as for patients with a length of stay greater than one day. The disease severity is lower. Calculated §21-KHEntgG cost data thus form a reliable basis for the calculation of appropriate reimbursement for hospital services to be provided as outpatient services under the AOP in the future.

Serum electrolytes, osmolality, and cleansing quality after bowel prep for colonoscopy with a PEG solution containing ascorbic acid and electrolytes.

BACKGROUND: The cleansing procedure with PEG 3350 + ascorbic acid (PEG + Asc; Moviprep®) requires the additional ingestion of clear liquids. We aimed to determine the effects on serum electrolytes, osmolality and cleansing quality, and in a prospective "real world" trial. PATIENTS AND METHODS: Patients underwent a standardized split-dose bowel preparation for colonoscopy with PEG + Asc. Serum electrolytes and osmolality were measured before and after the prep procedure. The volume of prep solution (PA) and additional clear liquid (CL) was recorded. Prep quality was assessed using the Ottawa Bowel Prep Grading Scale (OBPS). The primary outcome measures were changes of serum electrolytes and osmolality during the cleansing procedure. A secondary end point was the OPBS. RESULTS: One hundred ninety-one of 219 patients entered the per protocol analysis. Prep quality was considered excellent in 57.6%, moderate in 20.9%, and insufficient in 21.5%. The number of patients with hyponatremia increased from 12 (6.3%) before to 25 (13.2%) after the prep procedure. Mean sodium concentration did not change significantly. The volume of CL correlated inversely with Na+ concentration (r = - 0.409, p < 0.01) and a worse OBPS (r = 0.198, p < 0.01). CONCLUSIONS: Bowel preparation with PEG-Asc in clinical routine is generally safe, but patients should be advised not to drink more than 2 l of clear liquid because of imminent electrolyte disturbances. Additionally, the quality of cleansing either remains unchanged or may even worsen.

Technical success, resection status, and procedural complication rate of colonoscopic full-wall resection: a pooled analysis from 7 hospitals of different care levels.

INTRODUCTION: Endoscopic full-thickness resection (eFTR) using the full-thickness resection device (FTRD®) is a novel minimally invasive procedure that allows the resection of various lesions in the gastrointestinal tract including the colorectum. Real-world data outside of published studies are limited. The aim of this study was a detailed analysis of the outcomes of colonoscopic eFTR in different hospitals from different care levels in correlation with the number of endoscopists performing eFTR. MATERIAL AND METHODS: In this case series, the data of all patients who underwent eFTR between November 2014 and June 2019 (performed by a total of 22 endoscopists) in 7 hospitals were analyzed retrospectively regarding rates of technical success, R0 resection, and procedure-related complications. RESULTS: Colonoscopic eFTR was performed in 229 patients (64.6% men; average age 69.3 ± 10.3 years) mainly on the basis of the following indication: 69.9% difficult adenomas, 21.0% gastrointestinal adenocarcinomas, and 7.9% subepithelial tumors. The average size of the lesions was 16.3 mm. Technical success rate of eFTR was achieved in 83.8% (binominal confidence interval 78.4-88.4%). Overall, histologically complete resection (R0) was achieved in 77.2% (CI 69.8-83.6%) while histologically proven full-wall excidate was confirmed in 90.0% (CI 85.1-93.7%). Of the resectates obtained (n = 210), 190 were resected en bloc (90.5%). We did not observe a clear improvement of technical success and R0 resection rate over time by the performing endoscopists. Altogether, procedure-related complications were observed in 17.5% (mostly moderate) including 2 cases of acute gangrenous appendicitis requiring operation. DISCUSSION: In this pooled analysis, eFTR represents a feasible, effective, and safe minimally invasive endoscopic technique.

Small intestinal dysmotility in cirrhotic patients: correlation with severity of liver disease and cirrhosis-associated complications.

INTRODUCTION: Altered small intestinal motility has been observed in various manometry studies in patients with cirrhosis. Since small bowel manometry is available only in a few centers, interpretation of dysmotility in cirrhosis is controversial. PATIENTS AND METHODS: In this study, both fasting and postprandial manometric tracings of 24-hour antroduodenojejunal manometries were analyzed using both visual analysis and computer-aided analysis. RESULTS: In 34 patients (83 %), the mean migrating motor complex (MMC) cycle length was different compared with healthy controls. Phase II was prolonged in 27 patients (66 %), while phase I showed a reduced duration in 23 (56 %) and in phase III in 13 individuals (32 %). We also observed special motor patterns, e. g., migrating clustered contractions (MCCs) or retrograde clustered contractions (RCCs), which were present during fasting (69 %) and postprandial (92 %) motility, while none of the healthy controls showed any special motor patterns. Special motor patterns showed a significant correlation with the severity of cirrhosis (Child-Score; p > 0.05) and the existence of ascites (p < 0.05). DISCUSSION: This study in a large cohort of patients with cirrhosis by using 24-hour, solid state portable manometry showed in most individuals disturbances of cyclic fasting motility. Special motor patterns like RCCs during fasting and postprandial motility could be observed exclusively in the cirrhosis group, showing a significant correlation with severity of cirrhosis and the occurence of associated complications.

Overlap of concurrent extrahepatic autoimmune diseases is associated with milder disease severity of newly diagnosed autoimmune hepatitis.

BACKGROUND: Concurrent extrahepatic autoimmune disorders (CEHAID) are frequently observed in autoimmune hepatitis (AIH). It is not clear whether there is any prognostic significance of CEHAID on AIH. The aim of this study was to examine the prognostic impact of CEHAID and the correlation with the disease severity of AIH. METHODS: This study included 65 hospitalized subjects who fulfilled the accepted criteria for AIH during an 8-year period (2009-2016). All records were manually screened for presence of associated autoimmune diseases. Disease severity of AIH was assessed by liver laboratory tests including the ratio of aspartate aminotransferase to alanine aminotransferase (AST/ALT) and liver histology. RESULTS: Among the enrolled patients, 52 (80%) were female (median age 61 years, IQR 45-75). Fifty-six (86.2%) were classified as type-1 AIH. In 26 (40%) patients at least one additional extrahepatic autoimmune disease was diagnosed. Thirty-four subjects were referred to our hospital because of acute presentation of AIH (supposed by an acute elevation of hepatic enzymes) for subsequent liver biopsy resulting in initial diagnosis of AIH. This group was stratified into 3 subgroups: (A) AIH alone (n = 14); (B) overlap with primary biliary cirrhosis (PBC) / primary sclerosing cholangitis (PSC) (n = 11); and (C) with CEHAID (n = 9). AST/ALT ratio was the lowest in subgroup C (median 0.64, IQR 0.51-0.94; P = 0.023), compared to subgroup A (median 0.91, IQR 0.66-1.10) and subgroup B (median 1.10, IQR 0.89-1.36). Patients with AIH alone showed a trend to the highest grade of fibrosis (mean 2.3; 95% CI: 1.5-3.0) with no statistical significance compared to subjects with CEHAID (lowest grade of fibrosis; mean 1.5; 95% CI: 0.2-2.8; P = 0.380) whereas the ongoing inflammation was comparable. CONCLUSIONS: AST/ALT ratio and extent of fibrosis were lower in subjects with AIH and CEHAID, compared to subjects with only AIH. Therefore, the occurrence of CEHAID might be a predictor for lower disease severity of newly diagnosed acute onset AIH, possibly caused by an earlier diagnosis or different modes of damage.

Damage control strategy in perforated diverticulitis with generalized peritonitis.

BACKGROUND: The best treatment for perforated colonic diverticulitis with generalized peritonitis is still under debate. Concurrent strategies are resection with primary anastomosis (PRA) with or without diverting ileostomy (DI), Hartmann's procedure (HP), laparoscopic lavage (LL) and damage control surgery (DCS). This review intends to systematically analyze the current literature on DCS. METHODS: DCS consists of two stages. Emergency surgery: limited resection of the diseased colon, oral and aboral closure, lavage, vacuum-assisted abdominal closure. Second look surgery after 24-48 h: definite reconstruction with colorectal anastomosis (-/ + DI) or HP after adequate resuscitation. The review was conducted in accordance to the PRISMA-P Statement. PubMed/MEDLINE, Cochrane central register of controlled trials (CENTRAL) and EMBASE were searched using the following term: (Damage control surgery) AND (Diverticulitis OR Diverticulum OR Peritonitis). RESULTS: Eight retrospective studies including 256 patients met the inclusion criteria. No randomized trial was available. 67% of the included patients had purulent, 30% feculent peritonitis. In 3% Hinchey stage II diverticulitis was found. In 49% the Mannheim peritonitis index (MPI) was greater than 26. Colorectal anastomosis was constructed during the course of the second surgery in 73%. In 15% of the latter DI was applied. The remaining 27% received HP. Postoperative mortality was 9%, morbidity 31% respectively. The anastomotic leak rate was 13%. 55% of patients were discharged without a stoma. CONCLUSION: DCS is a safe technique for the treatment of acute perforated diverticulitis with generalized peritonitis, allowing a high rate of colorectal anastomosis and stoma-free hospital discharge in more than half of the patients.

[Prognostic significance and economic burden of hepatic encephalopathy in liver cirrhosis in German hospitals based on G-DRG data]. / Mortalität und ökonomische Auswirkungen der hepatischen Enzephalopathie bei Leberzirrhose in deutschen Krankenhäusern auf der Basis von G-DRG-Kostendaten.

INTRODUCTION: Hepatic encephalopathy (HE) represents a frequent complication of liver cirrhosis with negative effects on patients' lives. The prevalence of clinical HE is estimated to be between 30-45 %. Regardless of its clinical and prognostic relevance HE is considered to be underdiagnosed. METHODS: Beyond a systematic analysis of mortality of HE, we investigated the economic impact and reimbursement situation for HE in patients with liver cirrhosis in Germany. For the retrospective analysis, anonymized data (2011-2015) concerning expenses and diagnoses (§â€Š21-4 KHEntgG) were obtained from 74 participating hospitals of the Diagnosis Related Groups (DRG) Project of the German Gastroenterological Association (DGVS). Furthermore, results were compared with case data from all German hospitals provided by the German Federal Authority on Statistics (Statistische Bundesamt (Destatis), Wiesbaden). RESULTS: In participating hospitals 59 093 cases with liver cirrhosis were identified of which 14.6 % were coded as having HE. Hospital mortality was threefold increased compared to cirrhosis-patients without HE (20.9 versus 7.5 %). Cases with cirrhosis as well as the proportion with HE increased over time. Compared to all patients with cirrhosis, reimbursement for HE patients produced a deficit (of up to 634 € for HE grade 4). DISCUSSION: Mortality is threefold increased in patients with cirrhosis when an additional HE is diagnosed. Hospitals participating in the DGVS-DRG-project coded 2 % more HE cases among their cirrhosis cases than the rest of hospitals either because of a selection bias for greater disease severity or because of better coding quality. At present, reimbursement for HE patients on the basis of F-DRG-system produced a deficit.

[Patient perception and approval of fecal microbiota transplantation (FMT) as an alternative treatment option for ulcerative colitis]. / Akzeptanz des fäkalen Mikrobiota-Transfers (Stuhltransplantation) als alternative Therapie bei Patienten mit Colitis ulcerosa.

INTRODUCTION: Fecal microbiota transplantation (FMT) represents a treatment option for recurring Clostridium difficile-associated colitis. However, there is also evidence that FMT can be effective in treating ulcerative colitis. This study examined the approval and willingness of affected patients who underwent FMT. METHODS: A standardized questionnaire containing 27 polar and open questions was dispatched to a cohort of 262 patients suffering from UC. It included questions regarding the FMT process, donors, and possible concerns. Additionally, aspects of social background and disease activity were addressed. RESULTS: The response rate was 31.3 % (n = 82). Forty-eight (58.5 %) patients were already aware of FMT. Forty-six (56.1 %) were willing to undergo FMT if given a respective indication. The effectiveness of the procedure (40.2 %), followed by failure of all other therapies (17.1 %), formed the principal motivation. The transmission of possible infectious agents (26.8 %), and the potential contamination of the stool graft leading to a deterioration of clinical symptoms, raised the most concerns. (20.7 %).The preferred delivery system of FMT was capsules (67.1 %), followed by colonoscopic application (47.6 %). The patients were in favour of a donor proposed by the physician (52,4 %). Willingness to undergo FMT did not differ significantly between genders (56.4 % women vs. 57.1 % men). Smokers (88.9 %), patients who did not watch television at all (77.8 %) and those with private health insurance, showed an increased willingness to undergo FMT. CONCLUSION: For the majority of the UC patients surveyed, FMT represents a feasible treatment option. Approximately half of the respondents would consider FMT as an alternative treatment option, even inspite of a satisfactory disease response to current standard therapies. Unsurprisingly, there are concerns regarding the transmission of possible infectious agents and the hygienic implementation of FMT itself.

[Updated S2k-Guideline "Complications of liver cirrhosis". German Society of Gastroenterology (DGVS)]. / Aktualisierte S2k-Leitlinie der Deutschen Gesellschaft für Gastroenterologie, Verdauungs- und Stoffwechselkrankheiten (DGVS) "Komplikationen der Leberzirrhose".

This guideline provides evidence-based key recommendations for diagnosis and therapy of complications of liver cirrhosis and upgrades the 2011 version. An interdisciplinary team of medical experts and patient support groups developed the guideline following the AWMF recommendations for evidence based consensus guidelines. New chapters concerning diagnosis and therapy of hepatic encephalopathy were added.

Design of the Weight-loss Endoscopy Trial (WET): a multi-center, randomized, controlled trial comparing weight loss in endoscopically implanted duodenal-jejunal bypass liners vs. intragastric balloons vs. a sham procedure.

BACKGROUND: Obesity is a global problem leading to reduced life expectancy, cardiovascular diseases, diabetes and many types of cancer. Even people willing to accept treatment only achieve a mean weight loss of about 5 kg using commercial weight loss programs. Surgical interventions, e.g. sleeve gastrectomy or gastric bypass are effective but accompanied by risk of serious complications and side effects. Less invasive endoscopic procedures mainly comprise the intragastric balloon (IB) and the duodenal-jejunal bypass liner (DJBL). To date, a randomized comparison between these devices has not been undertaken or shown to be superior to a sham procedure. METHODS: We designed a multi-center, randomized, patient and assessor-blinded, controlled trial comparing weight loss in endoscopically implanted IB vs. DJBL vs. a sham procedure. A total of 150 patients with a BMI > 35 kg/m2 or > 30 with obesity-related comorbidities and indication for proton pump inhibitors are randomized to receive either IB, DJBL or a sham gastroscopy (2:2:1 ratio). All participants undergo regular dietary consultation. The IB will be removed after 6 months, whereas the DJBL will be explanted after 12 months. All patients will receive gastroscopies at implantation and explantation of the devices or sedation without gastroscopy to maintain blinding. Main exclusion criteria are malignant diseases, peptic ulcer or previous bariatric intervention. Weight loss 12 months after explantation of the devices, changes in comorbidities, quality of life, complication rates and safety will be evaluated. DISCUSSION: This trial could help to identify the most effective and safest endoscopic device, thus determining the new standard procedure for endoscopic bariatric treatment. TRIAL REGISTRATION: 16th January 2017. DRKS00011036. Funded by the German Research Foundation (DFG).

Olfactory Function is Affected in Patients with Cirrhosis Depending on the Severity of Hepatic Encephalopathy.

INTRODUCTION AND AIM: Olfactory functions are altered to a variable degree by chronic liver disease. Few studies including only small populations of patients emphasized the possibility of hepatic encephalopathy (HE) influencing olfactory nervous tasks. So far, no study has explicitly focused on olfactory function depending on the severity of HE as assessed by objective diagnostic procedures. Thus we performed a study using the "Sniffin' Sticks" test system, critical flicker-fusion frequency (CFF) and clinical West Haven criteria. MATERIAL AND METHODS: 54 cirrhotic patients with liver cirrhosis were included. Furthermore, 43 adult volunteers participating as a non-cirrhotic control group. Olfactory testing was performed using the "Sniffin' Stick" test battery (Burghart Medizintechnik, Wedel, Germany) which renders a widely-used tool both in clinical and research settings for the assessment of olfactory threshold, odor identification and discrimination. Several complications of cirrhosis were diagnosed by reference methods. Statistical analysis of cirrhosis-associated complications and their relation to olfactory function was performed. Assessment of HE and classification of different stages were performed according to clinical criteria (West- Haven criteria) and according to CFF, which was determined using a portable analyzer. RESULTS: Olfactory function was significantly reduced in cirrhotic patients (in 61.1%) compared to controls (p < 0.001). Among cirrhotics patients, the prevalence of olfactory deficits (hyposmia, anosmia) increased with the severity of HE as assessed by CFF and clinical criteria (p = 0.008 and p = 0.097, respectively). No correlation was observed between olfactory deficits and severity of liver disease as assessed by Child-Pugh-Score, etiology of cirrhosis and complications of cirrhosis such as ascites and portal venous hypertension. CONCLUSIONS: Olfactory testing serves as a screening tool for HE and may facilitate grading of HE-severity.

[Liver disease in systemic Lupus erythematodes - results of an explorative observational study]. / Hepatopathie bei systemischem Lupus erythematodes ­ Ergebnisse einer explorativen Beobachtungsstudie.

INTRODUCTION: Systemic lupus erythematodes (SLE) represents an autoimmune disease with a highly variable clinical course affecting numerous organs. Hepatic manifestation seems to be rare. It is not clear whether hepatic disease in SLE is of any prognostic importance or whether it correlates with disease activity. METHODS: Our patient cohort included 172 patients with proven SLE, all treated at Bogenhausen Hospital between 01.2009 and 12.2015. Retrospectively, all admissions as inpatients and outpatients were analyzed (n = 671; mean 3.9 per patient). Liver damage was diagnosed by evaluation of laboratory parameters on the basis of pathological liver enzymes and by imaging methods. Disease activity of SLE was calculated by using European Consensus Lupus Activity Measurement-(ECLAM-)Score. Additionally, parameters of SLE including disease duration, organ damage and immune suppressive medication and their possible association with hepatopathy were analyzed. RESULTS: Elevated liver parameters (ASAT, ALAT, GGT, AP) indicating liver damage were detectable in 109 patients (63.4 % of total population) demonstrating significant association with disease activity (on the basis of ECLAM-score, p < 0.001), duration of treatment, frequency of admissions (p < 0.01, respectively), number of used immunosuppressive agents (p < 0.018), increased blood sedimentation rate (p < 0.001) and reduction of serum complement (p < 0.03). Abnormal ultrasound findings of the liver (e. g., non-alcoholic fatty liver disease) were diagnosed in 19.8 %. DISCUSSION: Elevated liver parameters occur frequently in patients with SLE, especially in context with increased disease activity (on the basis of ECLAM-Score or intensified immunosuppressive therapy) and prolonged course of the disease. Liver enzymes should be obtained regularly in patients with SLE and, if necessary, further diagnostic steps should be initiated. Further prospective studies might clarify whether abnormal liver parameters must be included in activity indices to judge disease activity in SLE.

Traveler's Diarrhea, vision abnormalities and unsteady gait in a young woman.

We report on the course of disease in a young woman, originally admitted with suspected refractory infectious tropical traveler's diarrhea. However, symptoms did not resolve upon either symptomatic or subsequent antibiotic therapy. When neurologic deterioration was observed, imaging studies revealed a dramatic series of thromboembolic events, including intracranial hemorrhage caused by extensive sinus vein thrombosis as well as thrombi of the right cardiac ventricle. Colonic mucosal biopsy samples finally led to the histologic diagnosis of ulcerative colitis. Having excluded thrombophilia or any other disease potentially related to a prothrombotic state, we interpreted the thromboembolic events as secondary to the primary manifestation of the underlying inflammatory bowel disease.The increased risk of thromboembolic complications-especially deep vein thrombosis and pulmonary embolism-in inflammatory bowel disease is well documented in the literature. However, sinus vein thrombosis and cardiac thrombi represent a remarkable dimension of this risk and a rare course of coagulopathy secondary to an acute flare of ulcerative colitis. Still, there is a lack of awareness of this risk, resulting in poor implementation of preventive measures modifying risk factors and allowing for pharmacological prophylaxis. We therefore emphasize that-in line with the 2014 German S3 Guideline-thromboprophylaxis in the setting of an acute flare of inflammatory bowel disease is mandatory and should not be restricted because of safety concerns.
