[Autoimmune diagnostics in nephrology and rheumatology]. / Autoimmundiagnostik in der Nephrologie und Rheumatologie.

Autoimmune diagnostics plays a central role in the detection of various acute and/or chronic diseases in both nephrology and rheumatology, which are associated with high morbidity and mortality if left untreated or not detected in time. Patients are threatened with significant limitations in everyday skills and quality of life due to loss of kidney function and dialysis, immobilizing and destructive joint processes or also significant damage of organ systems. In all of these autoimmune diseases, early diagnosis and treatment is of central importance for the further course and prognosis of disease.Antibodies play an essential role in the pathogenesis of autoimmune diseases. Antibodies are either directed against organ or tissue-specific antigens, such as in primary membranous glomerulonephritis or Goodpasture's syndrome, or they lead to a systemic disease such as systemic lupus erythematosus (SLE) or rheumatoid arthritis.Knowledge of the sensitivity and specificity of antibodies is crucial for the interpretation of antibody diagnostics results. Antibody detection can precede the clinical onset of the disease, and antibody titers often reflect disease activity. However, there are also false positive results. Detection of antibodies in the absence of disease symptoms often leads to uncertainty and unnecessary further diagnostics. Therefore, an unfounded "antibody screening" is not recommended.A rational antibody diagnostics is an integral part of the diagnostics and during treatment of nephrological and rheumatological diseases like glomerulonephrititis, pulmorenal syndrome, SLE and other collagenosis, thrombotic microangiopathy (HUS/TTP) and rheumatoid arthritis.

[Current patient care of giant cell arteritis in Rhineland-Palatinate]. / Versorgungssituation der Riesenzellarteriitis in Rheinland­Pfalz.

BACKGROUND: Giant cell arteritis (GCA) is one of the most common forms of inflammatory vasculitis in older patients. Because of possible irreversible vision deterioration, a fastest possible diagnosis and therapy is of absolute importance. To date, there are still no reliable data to obtain an initial assessment of the outpatient health care situation of patients diagnosed with GCA in Rhineland-Palatinate. METHODS: The specialists (neurologists, rheumatologists, ophthalmologists and general practitioners) participating in the statewide rheumatology network ADAPTHERA were questioned with the help of a questionnaire regarding disease frequency, activity, drug therapy and possible comorbidities. In addition, the collected data were compared and supplemented by the ambulatory coding of the Association of Statutory Health Insurance Physicians in Rhineland-Palatinate. RESULTS: Based on the information provided by general practitioners, 272 GCA patients were treated in Rhineland-Palatinate during the survey period. The average duration of the disease until diagnosis was 3.6 (SD ± 4.8) months. Drug therapy in the form of glucocorticoids was in first place followed by methotrexate, acetylsalicylic acid (ASA) and azathioprine. Cardiovascular diseases, chronic pain syndromes, depression, osteoporosis and diabetes mellitus were also described as comorbidities. CONCLUSION: The majority of patients with GCA are being cared for by general practitioners (GP). Long-term therapy and timely rheumatological co-treatment seem to be problematic. The primary care providers expressed their wishes for rheumatological training and further education measures. In terms of diagnosis and treatment, there is a demand to implement a "vasculitis fast-track" module.
