title: [Chronic lymphocytic leukemia complicated by pernicious anemia during long-term remission].
abstract: Chronic lymphocytic leukaemia was diagnosed in 1957 in a 29-year-old male patient who lived 31 years after that time. At the time of diagnosis he was in good general condition with the enlarged liver (4 cm) and spleen (5 cm). In peripheral blood the leukocyte count was 47 x 10(9)/1 with 80% lymphocytes (38 x 10(9)/1), Hb 106 g/1; the bone marrow showed hypercellularity with predominance of lymphocytes. Treatment with corticosteroids was during 1958-1966. In 1967 Chlorambucil was given for 3 months, in 1972 for one month, inducing normalization of leukocyte count, 5.7 x 10(9)/1 with 40-50% of lymphocytes (3 x 10(9)/1). In 1977 the bone marrow showed slight lymphocytosis (38%). Numerous infections were recorded. Splenomegaly disappeared in 1980. In 1982 macrocytic anaemia was observed. Diagnosis of pernicious anaemia was established based on megaloblastic bone marrow and positive Schilling test. Vitamin B12 treatment resulted in reticulocyte response (crisis) and normalization of haemoglobin level. In 1988 light anaemia and melena appeared. Gastroscopy revealed lesions in the fornix histologically identified as ventricular carcinoma. It can be presumed that the appearance of pernicious anaemia as an autoimmune disease is analogous to other autoimmune complications in chronic lymphocytic leukaemia (haemolytic anaemia, thrombocytopenia).
