[Integrated management of patients with chronic inflammatory bowel disease in the Rhine-Main Region: results of the first integrated health-care project IBD in Germany]. / Integrierte Versorgung von Patienten mit chronisch-entzündlichen Darmerkrankungen im Rhein-Main-Gebiet: Ergebnisse der ersten integrierten Versorgung CED in Deutschland.

INTRODUCTION: In our previous studies investigating the drug therapy in patients suffering from inflammatory bowel disease (IBD) in the Rhein-Main region, Germany, we detected serious discrepancies between treatment reality and treatment guidelines. Consecutively, patient outcome in this cohort was compromised. Following this pilot project a network between primary deliverers of care for IBD patients and one large health-care insurance company [BKK Taunus (Gesundheit), the second largest insurance company in Hessen, Germany] was established. PATIENTS AND METHODS: An analysis of treatment and socioeconomic data from 220 IBD patients (Crohn's disease - CD = 96, ulcerative colitis - UC = 124) entering the integrative health-care programme between 1.1.-30.9.2009 was performed. RESULTS: Remission rates for CD and UC in the integrated health-care programme could be improved from 60 - 73 % (CD) and from 61 - 79 % (UC). Guideline-conform treatment was observed in 81 % of patients with CD and 85 % with UC, respectively. Although medication costs increased, total costs could be cut by 162 304.- €, as secondary costs for hospitalisation and days off work could be reduced. CONCLUSION: The study shows that networking of deliverers of care for IBD patients with health insurances provides an excellent possibility to optimise medical treatment and can cut down costs significantly.

Health care and cost of medication for inflammatory bowel disease in the Rhein-Main region, Germany: a multicenter, prospective, internet-based study.

BACKGROUND: Studies examining the treatment reality of IBD patients in Germany have been limited, as networking among deliverers of care and reliable documentation of medical, demographic, and economic data are lacking. The aim of the present study was to establish an internet-based treatment registry in order to evaluate treatment of IBD patients in Germany. METHODS: Between November 1(st), 2005, and January 31, 2007, 1024 outpatients with prevalent IBD from 10 gastroenterological private practices and 3 hospitals (UC = 439, CD = 567, ID = 18) were enrolled in the study. An internet-based registry was established that included data about medical history, disease status, diagnostic procedures, laboratory test results, and medical treatment. Data for private practices and hospitals were pooled in order to compare treatment habits between these types of medical facilities. The cost of medication was determined according to medications prescribed. RESULTS: There was no significant difference between the 2 patient groups in demographic and clinical characteristics. Marked differences were observed in medical treatment. The most frequently prescribed medications in the private practices for patients in remission and those with active disease were aminosalicylates and corticosteroids. Immunomodulators played a marginal role. In contrast, in the hospitals azathioprine/6-MP was predominantly used for the maintenance of remission. Patients with fistulizing CD were treated with infliximab. The mean annual cost of medications was 1826 +/- 1331euro/patient (median 1353euro) in the private practices and 1849euro +/- 2897euro/patient (median 960euro) at the University Hospital. CONCLUSIONS: The registry provides the first detailed data about the reality of treatment of IBD patients in Germany and reveals the necessity for networking among attending physicians in order to implement guidelines-conformed treatment.

Individual invitation letters lead to significant increase in attendance for screening colonoscopies: Results of a pilot study in Northern Hesse, Germany.

BACKGROUND: Colorectal cancer (CRC) is the second most common cancer in Germany. Screening colonoscopies are considered an effective tool for early detection and prevention of CRC and are recommended in Germany for citizens over the age of 55. To increase the participation rate for screening colonoscopies, an invitation procedure was initiated in parts of Germany for patients between the ages of 55 and 75 who had never undergone a screening colonoscopy before. METHODS: We examined the number of participating patients before, during, and after the invitation procedure and compared the number of the participating patients who received a cover letter with the participating patients from the control group. Additionally, we classified the findings of the colonoscopies including CRC, advanced adenomas, and polyps. RESULTS: During the invitation period, the participation rate of the invitation group increased from 220 patients to 531 patients compared to 1256 to 1693 in the control group. The increase was significantly greater in patients with cover letters (+141% vs.+35%, p < 0.0001). Also, significantly more polyps and adenomas were found in patients from the invitation letter group (254 (+102%) vs. 679 (-9%), p < 0.0001). CONCLUSIONS: Our study clearly indicates that personal invitation letters are an effective measure to increase overall participation rates in screening colonoscopies.

Female patients suffering from inflammatory bowel diseases are treated less frequently with immunosuppressive medication and have a higher disease activity: a subgroup analysis of a large multi-centre, prospective, internet-based study.

BACKGROUND: The introduction of immunosuppressants and biologic agents has led to active debate and research about optimal therapeutic strategies considering risk factors and predictors of clinical outcome in inflammatory bowel disease (IBD). Data about gender-specific treatment differences and risk factors is lacking for IBD. The aim of the present study was to evaluate gender-related differences in the treatment of a distinct IBD patient population treated in the Rhein-Main region, Germany. METHODS: Data about past medical history, disease status and medical treatment of 986 outpatients treated in ten gastroenterological practices and three hospitals were collected from November 1st 2005-July 31st 2007 and analyzed with regard to gender-related differences in therapy and disease management. RESULTS: With the exception of an extended disease duration in women, no significant gender-related differences in demographic and clinical characteristics were observed. Men showed a significantly higher remission rate than women (p=0.025), while women received significantly less immunosuppressive medication compared to men (p=0.011). In addition, treatment with immunosuppressants was not different in women with child-bearing potential compared to menopausal women. CONCLUSION: Our investigation demonstrates for the first time gender-specific differences in the therapeutic management in a large cohort of IBD patients.

[Effectiveness of antiviral therapy in patients with chronic hepatitis C treated by private practice gastroenterologists]. / Effektivität der antiviralen Behandlung von Patienten mit chronischer Hepatitis C in der gastroenterologischen Facharztpraxis.

The standard treatment for patients with chronic hepatitis C consists of pegylated interferon (PegIFN) alpha in combination with ribavirin. Information on treatment effectiveness outside clinical trials is sparse. To study community-based health care, a regional network supported by the German network of competence for hepatitis (Hep-Net) was created between gastroenterologists in private practice and a tertiary referral centre. A treatment register containing evidence-based guidelines was established and 212 consecutive patients who were treated with either PegIF Nalpha 2a/ribavirin (n = 126) or PegIFNalpha2b/ribavirin (n = 86) for 24 weeks (HCV genotype 2, 3) and 48 weeks (HCV genotype 1, 4, 5), respectively, were included and followed prospectively. Twenty-four weeks after cessation of antiviral treatment a sustained virological response was achieved in 54 % of the patients. By univariate analyses, infection with HCV genotypes 2 or 3 (p < 0.0001), younger age (p < 0.0001), normal gamma-glutamyltransferase levels before initiation of treatment (p = 0.003), and absence of language communication problems (p = 0.023) were associated with a sustained virological response. The presence of liver cirrhosis in patients with HCV genotype 1, 4, 5 infection was associated with lower sustained response rates (p = 0.025). Patients infected with HCV genotype 1 in whom the PegIFNalpha dose was reduced had higher virological relapse rates (p = 0.049). With regard to the treating physician, sustained virological response rates ranged from 26 - 67 % in patients infected with HCV genotype 1. Our study shows that virological response rates similar to those in international randomised clinical trials can be achieved by private practice gastroenterologists. The presented network allows characterization of the treatment outcome in chronic hepatitis C not only with regard to virus- and host-related factors but also on an individual physician basis.

Addition of senna improves colonoscopy preparation with lavage: a prospective randomized trial.

Attempts have been made to further improve the widely performed colonoscopy preparation with lavage. In a prospective study, 120 outpatients and inpatients scheduled for total colonoscopy were randomized to two preparatory regimens. The day before endoscopy either extractum sennae (N = 60) or a placebo solution (N = 60) was given. Just before examination all patients underwent whole gut irrigation with a polyethylene glycol electrolyte lavage solution (PEG-ELS). Adequacy of preparation, patient tolerance, and the necessary amount of PEG-ELS were assessed. Physician assessment of colon cleansing showed superiority in the group with additional laxative. The colon was free of solid debris in 66.7% of patients after PEG-ELS and in 90% after senna/PEG-ELS administration (p less than 0.01). Patient tolerance was similar in both groups with 86.7% vs. 83.3% of subjects rating the preparation as tolerable. Severe adverse events were not observed. In the senna/PEG-ELS group, significantly less (p less than 0.05) lavage fluid was needed. We conclude that the combination of senna and PEG-ELS is more effective than PEG-ELS in cleansing the colon for colonoscopy.

Senna vs. bisacodyl in addition to Golytely lavage for colonoscopy preparation--a prospective randomized trial.

Colonoscopy preparation with lavage is a clinically accepted procedure. After having shown that its results can be improved by the additional intake of Senna this randomized prospective trial was designed to evaluate the effects of different laxatives in a combined preparation regimen. The day before endoscopy either Bisacodyl or extractum Sennae was given to 120 patients. Immediately before examination all patients underwent whole gut irrigation with Golytely solution. Patient acceptance and effectiveness of the two procedures were excellent and no relevant intolerance was observed. Satisfactory cleansing results were achieved with Bisacodyl as well as with Senna (98.3 vs. 95%). There was no significant difference between the laxatives used. We conclude that both regimens are safe, generally well tolerated and effective ways of preparation for colonoscopy.

[Endosonographic findings in the upper gastrointestinal tract in staging of malignant nodal and extranodal lymphomas]. / Endosonographische Befunde des oberen Gastrointestinaltraktes beim Staging maligner nodaler und extranodaler Lymphome.

Endoscopic ultrasound has not yet become a routine procedure for the diagnosis and therapy planning of malignant lymphomas, and it was always restricted to patients with gastric or bowel involvement. From 1990 to 1992, 33 endoscopic ultrasound investigations have been performed in 25 patients with malignant lymphomas at the Cologne University Hospital. In addition, 21 of these patients had other (conventional) diagnostic procedures at the same time serving as reference. Endoscopic ultrasound showed lymphomas in 16/21 patients, and no evidence of lymphomas in 5/21 patients. The referencial investigations together showed lymphomas in 17/21 patients, and no evidence of lymphomas in 4/21 patients. Therefore, sensitivity was 94%. 5 of the patients in addition had involvement of the upper gastrointestinal tract's wall, proven by referencial investigations, which was diagnosed correctly in all cases. The pathological lymph nodes appeared mostly as echopoor, rather sharply demarcated and homogeneous. Their size was 7 mm to 55 mm in diameter, median 11 mm. The different histological types of lymphomas could not be distinguished by means of these criteria. Endoscopic ultrasound allows a detailed view at the mediastinal and epigastrical lymph node stations and may give important informations for the staging of malignant lymphomas.

Combined treatment of large and calcified gallstones by ESWL and laparoscopic cholecystectomy.

In order to facilitate laparoscopic cholecystectomy in the presence of large gallbladder stones seven patients underwent ESWL before operation. In six cases (83%) a fragmentation to less than or equal to 1 cm could be achieved by application of 1,605 to 2,900 (mean 2,266) shock waves with the spark-gap lithotripter Philips-Dornier MFL 5000. In these cases intraoperative stone destruction or an increase of the puncture incision size could be avoided, thus proving the efficacy of this combined treatment approach. Laparoscopic inspection was performed 2 to 48 hours after ESWL. Including two additional cases operated because of unsuccessful ESWL, hematomas of the liver and adjacent organs were observed in six of nine patients (67%). This high rate of subclinical tissue lesions warrants caution if repeated ESWL sessions are scheduled at short-term intervals.

Comparison between endoscopic laser and different surgical treatments for palliation of advanced rectal cancer.

The results of different treatment modalities in 196 patients with rectal carcinoma were analyzed. Patients were treated by palliative endoscopic laser therapy (n = 37), palliative surgery (n = 42), and curative surgery (n = 117). Laser therapy was successful for recanalization of the stenosis with 1.3 (range, one to five) sessions. Bleeding stopped always after a single session. If necessary, treatment was repeated monthly. Good results were seen in 35/37 patients (95 percent). They received an average of four sessions during their remaining lifetime, the median of which was eight months. No morbidity and no therapy-related mortality occurred. Palliative surgery (expanded and restricted resections) showed good results in 41/42 patients (98 percent). Morbidity was 3/42 (7 percent); mortality was 1/42 (2 percent). The median survival was 14 months for local surgical treatment and 6.3 months for deep anterior rectal resection and for abdominoperineal (Dixon's) resection. No significant difference (P = 0.15) in survival times between the palliatively treated patient groups could be detected. Survival prognosis was determined by tumor stage and outcome. In the curative (outcome R0) resection patients, morbidity and mortality were each 9/117 (8 percent). The three-year survival rate was 80 percent. If curative resection is impossible, laser therapy should be considered as an alternative to palliative surgery because of less hospitalization and seemingly less side effects. The decision on the kind of palliation in patients with rectal carcinoma should be made with regard to the patient's quality of life.
