[Current initiatives in Germany for translating national guidelines into reality - a survey]. / Aktuelle Initiativen zur Realisierung nationaler Leitlinien in Deutschland - eine Ubersicht.

The role of practice guidelines as a tool for quality management in health care is now widely accepted in Germany- not only by health professionals, but also in politics. The physicians' professional associations as well as health care authorities (physicians' self-governmental bodies) and parliament introduced several incentives and regulations, aiming at a regular use of guidelines in health care. Among these the German guideline clearinghouse with the systematic approach towards identification, dissemination, and implementation of best available evidence-based guidelines, as well as the country-wide implementation of disease management guidelines seem to be effective and efficient in quality management as well as in patient care management in the German health care system. The article gives an overview on background, procedures and barriers to country-wide implementation of clinical practice guidelines within a social security health care system.

Current status of multiple sclerosis therapy in Germany: a national survey.

We conducted a semi-standardized enquiry concerning diagnostic, immunotherapeutic and supportive care strategies for multiple sclerosis (MS). A questionnaire was sent to all German neurological departments in December 1996, with 63% (n = 244) responding before May 1997. As might be expected, MS therapy in Germany is not very standardized. Most clinics use intravenous steroids for treating relapses, although with different dosing regimens. Nevertheless, oral steroids are also used. Interferon-beta and azathioprine are both used for the treatment of relapsing-remitting MS at the same frequency. Only 33% of German neurological departments said that they used an immunomodulating agent for chronic-progressive cases, indicating it in about 50% of cases. Azathioprine is the drug of first choice, followed by methotrexate. Regarding supportive care measures, the technique of intermittent self-catheterization is widely under-represented. Despite the lack of conclusive evidence from prospective studies for the value of azathioprine, it is still one of the most commonly used drugs for the treatment of relapsing-remitting and chronic-progressive MS. There was no evidence of a consensus on treatment standards for chronic-progressive disease courses.

Detection of a soluble form of the CD30 antigen in sera of patients with lymphoma, adult T-cell leukemia and infectious mononucleosis.

Using a sandwich enzyme-linked immunosorbent assay (ELISA) we were able to detect a soluble form of the CD30 antigen (CD30s) in the supernatant of cell lines expressing membrane-bound CD30 and in T and B cells after transformation with human T-cell leukemia virus (HTLV-I) and Epstein-Barr-Virus (EBV). While CD30s was not found in 250 healthy controls, it was detected in the sera of patients with Hodgkin's disease (23/100), anaplastic large-cell (6/9), angioimmunoblastic (2/2) and one unclassified high-grade non-Hodgkin's lymphoma (NHL), as well as in 18/20 patients with acute adult T-cell leukemia (ATL, HTLV-I-positive). It was absent in a large number of patients with other high-grade NHL, all low-grade NHLs, acute or chronic leukemias and solid tumors. The only non-malignant disease with detectable levels of CD30s was infectious mononucleosis (9/10). The membrane-bound form of CD30 has a molecular weight of 120 kDa. Western blot analysis revealed that CD30s in the serum of patients has a molecular weight of 88 kDa, identical to the antigen released by cell lines in vitro. CD30s disappeared in all originally positive cases after successful treatment and reappeared in relapsing patients. Thus, CD30s may be useful as a specific marker for disease activity of certain types of lymphoma and ATL.
