Glomerulonephritis und malignes Lymphom : Überwiegend Männer mit niedrigmalignem Lymphom mit unterschiedlichen glomerulonephritisformen (Kasuistik)

□ BackgroundThe association of non-Hodgkin’s lymphoma with different types of glomerulonephritis is well-known for many years. Whereas in Hodgkin’s disease, minimal change glomerulonephritis is mainly observed, in non-Hodgkin’s lymphoma various forms of glomerulonephritis are found.□ Patients and ResultsWe describe 3 cases of non-Hodgkin’s lymphoma, which were assoicated with glomerulonephritis. Two cases of glomerulonephritis nephritis showed nephrotic syndromes, which improved by medicinal treatment. In 2 cases glomerulonephritis and non-Hodgkin’s lymphoma developed simultaneously. In a third lymphoma was followed by glomerulonephritis after 3 years.□ ConclusionAlthough the pathogenetic relationship between non-Hodgkin’s lymphoma and glomerulonephritis is not fully understood, the high number of reported cases yield interdependence. Lymphoma associated glomerulonephritis is found more often in men than in women. Low-grade non-Hodgkin’s lymphomas — especially chronic lymphatic leukemias — seem to develop glomerulonephritis more rrequently than high-grade. The majority of non-Hodgkin’s lymphoma do not show any predisposition to a special type of glomerulonephrits, only in cutaneous lymphoma IgA-nephropathy predominates.
