In addition to the primary glomerulonephritides described elsewhere in this issue, there is a group of diseases in which immune complex deposition or disturbances in complement regulation play a central pathogenic role. Among the most important and clinically relevant forms of these immune complex- and complement-mediated glomerulonephritides are postinfectious glomerulonephritis (PIGN), lupus nephritis (LN), cryoglobulinemic glomerulonephritis, and C3 glomerulopathy (C3G). While PIGN, LN, and cryoglobulinemic glomerulonephritis are characterized by glomerular immune complex deposits, C3 glomerulopathy is primarily based on a dysregulation of the alternative complement pathway. These diseases require specialized treatment in university outpatient clinics in collaboration with nephrology practices. Renal biopsy is a key diagnostic tool, and histologically, a membranoproliferative pattern is frequently observed. This article provides a systematic overview of immune complex- and complement-mediated glomerulonephritis and compares their pathogenesis, clinical presentation, immunoserological profiles, histology, and available therapies.</p>","PeriodicalId":73385,"journal":{"name":"Innere Medizin (Heidelberg, Germany)","volume":"67 5","pages":"506-514"},"PeriodicalIF":0.6,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147790987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are widespread diseases in the proper sense. Around 2.5 million people are hospitalized annually due to gastroenterological diseases and approximately 140,000 deaths per year are directly attributed to them. In addition, there are substantial impairments in the quality of life, high periods of inability to work and an immense economic burden on the healthcare system with annual costs of over €60 billion. It is particularly relevant that a substantial proportion of these diseases could be avoided or at least the course could be favorably influenced. The gastrointestinal tract including the liver and pancreas undertakes a key management function for the whole organism. Disorders of the digestive organs not only have a local effect but also influence the metabolism, cardiovascular system, immune system and the brain. Therefore, prevention in gastroenterology always also means prevention of systemic diseases. A healthy gut is a prerequisite for a healthy life. Prevention in gastroenterology is also a success story. The introduction of screening coloscopy, the vaccination against hepatitis B, the introduction of hepatitis B and C screening and the eradication of Helicobacter pylori demonstrably reduce the morbidity and mortality risks and impressively show the potential of a consistently implemented preventive strategy.

These highly prevalent conditions have a high morbidity and mortality. As many can be prevented by relatively simple nonpharmacological measures or effectively mitigated by low-threshold pharmacological interventions, they represent model diseases for prevention in internal medicine. This article outlines the current options and discusses them in the context of current prevention strategies. Endocrine and diabetic diseases are among the most common and consequential chronic disorders in industrialized countries and essentially contribute to the total morbidity and mortality. Principal preventive strategies include structural prevention (environmental prevention), such as promoting anti-adipogenic and anti-diabetogenic social structures and behavioral prevention. The emphasis of preventive strategies is on population-related measures, structured screening programs and evidence-based lifestyle interventions. Based on current epidemiological data and guidelines, practical approaches are presented, ranging from iodine prophylaxis, lipid and blood pressure screening to promotion of healthy bone and obesity preventive structures. The concepts discussed demonstrate that effective endocrine and diabetological prevention requires coordinated action across clinical medicine, public health and health policy to realize its full potential.</p>","PeriodicalId":73385,"journal":{"name":"Innere Medizin (Heidelberg, Germany)","volume":" ","pages":"30-34"},"PeriodicalIF":0.6,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13056723/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147357815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are several reasons for this: first, the examinations included in the check-up are insufficient. Second, the individuals who would benefit most often do not participate. Furthermore, the impact of prevention is difficult to quantify. Nevertheless, the check-up is an excellent tool for identifying individual risk factors and lifestyle diseases at an early stage and to react appropriately. It helps bridge vaccination gaps, reduce or delay multimorbidity, the need for long-term care and frailty until later in life, and strengthens the health literacy of the population.
