    Notes: Abstract PURPOSE: This study was designed to compare esophageal and anorectal function parameters in patients with systemic sclerosis and to define the role of anorectal manometry in the diagnosis of gastrointestinal involvement of systemic sclerosis. PATIENTS AND METHODS: Twenty-six consecutive patients (22 females) with systemic sclerosis originally referred for assessment of esophageal function were evaluated by esophageal and anorectal manometry. Anorectal function parameters were compared between patients with normal and those with disturbed esophageal function. RESULTS: A total of 17 of 26 patients (65 percent) had severe esophageal dysfunction with aperistalsis of the lower two-thirds of the esophagus, whereas 9 patients (35 percent) had normal esophageal manometry. Only three patients (11.5 percent) suffered from occasional fecal incontinence. Anorectal function parameters (resting pressure, maximum squeeze pressure, perception threshold) were not significantly different between patients with normal and those with disturbed esophageal motility. Rectoanal inhibitory reflex was excitable in nearly 90 percent of patients. CONCLUSION: In an unselected group of patients with systemic sclerosis, fecal incontinence and abnormal anorectal function are rather rare findings. Anorectal manometry cannot differentiate between patients with and without gastrointestinal involvement of systemic sclerosis.

    Notes: Abstract Inflammatory infiltrates and upregulated collagen production are hallmarks of systemic sclerosis (SSc). There are indications that chemokines are involved in accumulation of inflammatory and matrix-synthesizing cells in SSc skin lesions. Therefore, we searched for the expression and localization of the chemokine RANTES (“regulated upon activation and normal T cells expressed and secreted”) in skin and esophageal biopsies from patients with SSc. Using immunohistochemistry and in situ hybridization, skin biopsies derived from clinically involved and noninvolved skin of 18 patients with early and long-term SSc were examined for RANTES expression and compared with nondiseased skin sections of seven patients without SSc. In addition, esophageal snap biopsies were taken in a subgroup of six SSc patients. Strong expression of RANTES could be detected in the epidermis in keratinocytes of patients with short-term and long-term disease, both on the mRNA and protein level. The percentage of RANTES-expressing cells were significantly higher in clinically noninvolved skin sections than in involved skin areas. In contrast, no RANTES expression was found in esophageal biopsies or in the control group. The results indicate that RANTES is present in human sclerodermatous skin. RANTES may be involved in early pathogenesis of SSc as well as in fibrosis pathways, either by chemoattraction of immunocompetent cells and/or by modulation of collagen production.

    Notes: Abstract In 20 patients with systemic sclerosis (SSc) and 24 healthy controls, gallbladder motility was evaluated by abdominal ultrasonography after stimulation by a standard liquid meal. Results from patients with normal and dis turbed oesophageal function were analysed separately in order to investigate the significance of gallbladder motility as a parameter for gastrointestinal involvement in SSc. All patients showed a marked decrease in gallbladder size after stimulation (patients 61 ±13%; controls 48 ±12%). Patients with oesophageal dysfunction (n=12) had a slightly lower gallbladder contraction (maximal decrease =58±13%) when compared to patients with normal oesophageal function (n=8; 66± 13%); however, this difference was not statistically significant. Gallbladder motility in patients with SSc was not reduced when compared with healthy controls. SSc-induced oesophageal dysfunction was not associated with impaired gallbladder motility. Thus, measurement of gallbladder emptying is not a helpful tool when looking for gastrointestinal involvement in SSc.

    Description / Table of Contents: Abstract Background and Aim: According to the German consensus statement, the indication for treatment of HCV-RNA-positive chronic hepatitis C is not derived from histopathology but from elevated aminotransferases. The indication for liver biopsy has been discussed controversely. This study aimed at investigating the correlation between different biochemical and virological parameters and histological scores of inflammation and fibrosis in chronic hepatitis C. Patients and Methods: In a retrospective study, data of 126 patients with chronic hepatitis C who had undergone liver biopsy between January 1994 and March 1998 were analyzed. Histology was interpreted according to a defined numerical score of inflammation and fibrosis by a single pathologist. Scores of fibrosis and inflammation were correlated with biochemical and virological parameters. Results: Inflammatory grading showed a moderate but significant correlation with ALT (r = 0,33, p 〈 0.001), whereas staging of fibrosis did not correlate with ALT (r = 0.15). There was no association between grading or staging and HCV genotype (n = 110) or serum viral load (n = 57). Grading and staging showed a significant association with each other (p 〈 0.0001). Conclusion: Aminotransferases as “surrogate markers” reflect more or less the histological inflammatory activity but do not allow any estimation of the extent of fibrosis. Some patients may have a high inflammatory activity with low aminotransferases or high aminotransferases with low inflammatory activity. Virological parameters such as HCV genotype or viral load do not allow an estimation of histological findings. If prior to treatment of chronic hepatitis C liver biopsy is omitted and the decision for treatment depends solely on the measurement of surrogate markers, considerable misjudgment of the actual status of liver inflammation or fibrosis may result.
    Notes: Zusammenfassung Hintergrund und Ziel: Die Indikation zur Therapie der HCV-RNA-positiven chronischen Hepatitis C ergibt sich nach den derzeitigen deutschen Leitlinien nicht aus der Histologie, sondern durch das Vorliegen erhöhter Transaminasen. Die Indikation zur Gewinnung einer Leberhistologie vor Therapiebeginn wird kontrovers diskutiert. Ziel dieser Studie war die Untersuchung der Korrelation verschiedener biochemischer und virologischer Parameter mit dem histologischen Entzündungs- und Fibrosegrad bei chronischer Hepatitis C. Patienten und Methodik: In einer retrospektiven Untersuchung wurden die Daten von 126 Patienten analysiert, bei denen zwischen Januar 1994 und März 1998 bei chronischer Hepatitis C eine Leberpunktion durchgeführt worden war. Die Histologien wurden einheitlich von einem Pathologen nach einem numerischen Entzündungs- und Fibrosegrad analysiert. Entzündungs- und Fibrosegrade wurden korreliert mit biochemischen und virologischen Parametern. Ergebnisse: Der Entzündungsgrad korrelierte mit der Höhe der GPT (r = 0,33; p 〈 0,001) nicht aber das Fibrosestadiulm (r = 0,15). Weder Entzündungs- noch Fibrosegrad zeigten eine signifikante Korrelation mit dem HCV-Genotype (n = 110) oder der HCV-RNA-Kopienzahl im Serum (n = 57). Entzündungs- und Fibrosegrad waren hochsignifikant miteinander assoziiert (p 〈 0,0001). Schlußfolgerung: Transaminasen spiegeln als “Surrogatmarker” in etwa die histologische Entzündungsaktivität wider, erlauben jedoch keine Rückschlüsse auf das Fibrosestadium. Bei einem Teil der Patienten können jedoch durchaus eine hohe Entzündungsaktivität bei niedrigen Transaminasen oder hohe Transaminasen bei niedriger histologischer Entzündungsaktivität vorliegen. Virologische Parameter wie HCV-Genotyp oder HCV-RNA-Kopienzahl im Serum lassen keine Rückschlüsse auf den Entzündungsgrad oder das Fibrosestadium zu. Der Verzicht auf eine Leberhistologie vor Einleitung der Therapie einer Hepatitis C und die ausschließliche Bestimmung von “Surrogatmarkern” können zu einer deutlichen Fehleinschätzung der tatsächlichen Entzündungs- und Umbauvorgänge in der Leber führen.
