T., 65 years old, who had apparently had no previous disease, suffered in 1946 while in Mexico from an acute infection of undetermined etiology which lasted about 10 days. This episode was accompanied by a severe anemia (about 1,400,000 red blood cells per cubic millimeter). He was given five transfusions, one of which caused a very marked reaction. Since that time, the anemia has never disappeared. The skin has been pale and yellow-tinged. The patient always felt tired and had alternative periods of improvement and relapse. In 1946, splenomegaly had been discovered, the lower border of the spleen being felt at two or three fingerhreadth below the left costal margin. At that time, blood counts revealed a hematologic picture of pancytopenia: RBC, 3,090,000 per cubic millimeter, hemoglobin 82 per cent, hematocrit 32 per cent, M.C.V. 106 cubic microns, reticulocytes 1.3 per cent and 5 per cent. WBC, 2,900 per cubic millimeter with the following differential: neutrophils 34 per cent, eosinophils 1 per cent, basophils 1 per cent, lymphocytes 63 per cent, monocytes 1 per cent. Ameth’s classification showed a shift to the left. The platelets were 130,000 per cubic millimeter. Differential counts of bone marrow showed an increase of erythroblastic elements (50 per cent). Osmotic resistance was normal (4.8 - 3.2). No sickling of red blood cells was noted. The icterus Index was 9 on one occasion and 23.8 on another occasion (normal: 2 to 4). The qualitative Van den Bergh’s reaction was strongly positive. Urobilinogen was present In the urine to a dilution of 1/15. There was no hemosiderin in the urinary sediment. No occult blood was found in the urine or in the stools. The bleeding time was 3 to 4 minutes. The clotting time was 13 minutes. Prothrombin time was normal. The thymol turbidity test gave a result of 8.1 units. Bromsulfalein retention was 40 to 80 per cent. Blood urea was 0.19 per 1000 ml. serum proteins: 71 Gm. per 1000 ml. (albumin 46 Gm. per 1000 ml., globulin 25 Gm. per 1000 ml.). Alkaline phosphatase: 10 units. Biopsy of the liver did not show any lesion compatible with a diagnosis of cirrhosis. Cholecystography was done but the gallbladder was not visualized. To summarize: there was at that time a marked pancytopenia with signs of increased destruction of blood cells and accelerated regeneration, confirming the diagnosis of hemolytic anemia. Because of the palpable spleen, the diagnosis of splenic neutropenia was made. From www.bloodjournal.org by guest on December 22, 2014. For personal use only. ACQUIRED HEMOLYTIC ANEMIA AND 1081 ANTI-TN Between 1946 and 1952, the red blood counts have ranged from 2,100,000 to 3,350,000 per cubic millimeter, the mean being 2,500,000. The white blood counts oscillated between 3,900 and 1,300 per cubic millimeter, with a mean of 2,200. Neutrophils were always around 45 per cent, lymphocytes around 40 per cent. Reticulocyte count was 10 per cent on one occasion, but it was low usually. The general condition of the patient was never very satisfactory during that period and the course of the disease was interspersed with episodes of fatigue and increased icterus. However, these pathologic manifestations were so important as to keep the patient away from his work. One of us noted in 1950 the polyagglutinability of the patient’s red blood cells. It could be ascertained, however, that the patient was of group B because his serum contamed an anti-A agglutinin. On the same occasion, marked ovalocytosis was discovered (20 per cent of the erythrocytes were ovalocytes of Gunther’s group IV). On the first examination, in 1951, the following results were found: RBC, 2,715,000 per cubic millimeter; hematocrit, 30; mean diameter of red cells, 7 to 8 microns; M.C.V., [08 cubic microns; reticulocyte count, 8 per cent. The red cells had a tendency to autoagglutinate. There was marked anisocytosis with ovalocytosis. The hemoglobin was 60 per cent and the color index 1.1. M.C.H. was 32 micromicrograms and M.C.H.C. 29 per cent. The osmotic fragility test showed initial lysis at 5.4 and complete lysis at 3.4 per 1000 ml. The mechanical resistance of erythrocytes was slightly decreased. Acid-serum test, Crosby’s test and autohemolysis study gave normal results. Donath-Landsteiner’s test was negative. The WBC was 2,800 per cubic millimeter with the following differential: neutrophils, 42 per cent, eosinophils, 2 per cent, lymphocytes, 46 per cent, monocytes, 8 per cent, acidophilic normoblasts, 2 per cent. The platelets were 112,000 per cubic millimeter. Hemostasis studies showed a bleeding time at 4 minutes, a clotting time at 8 minutes, a normal clot retraction, a prothrombin time at 75 per cent, a slightly diminished prothrombin consumption and also a slightly diminished heparin tolerance. Serologic studies showed the persistence of polyagglutinability. There was no panagglutinin in the serum as seen in acquired hemolytic anemia. However a certain degree of autoagglutination was noted under the microscope. The search for hemolysins,2’ as well as the Donath-Landsteiner’s test, remained negative. In the serum a cold thromboagglutinin was detected, but no leukoagglutinin was found at that time. During the following months the general condition of the patient remained unchanged. In 1952, as well as on a few occasions afterwards, attacks of acute gouty arthritis supervened. Because of the persistence of the anemia, it was decided in 1953 to give the patient a few transfusions of washed B, Rh-negative red cells. These were perfectly tolerated at a frequency of one transfusion of 200 ml. every two weeks. The RBC reached 3,200,000 per cubic millimeter, but the \VBC remained at 1,200 per cubic millimeter and platelet count at 120,000. Some time later, an acute infection provoked a fall of the RBC to 1,500,000 per cubic millimeter. Six transfusions of washed cells were then necessary. At that point a leukoagglutinin was found in the serum. In 1955, the patient was treated with cortisone (from 200 to 350 mg. per day for three weeks) and then with prednisone (from 20 to 50 mg. per day). Improvement was remarkable and transfusions could be discontinued. Following that, RBC was between 2 and 3 million per cubic millimeter, WBC between 2,500 and 3,000 and platelet count around 200,000 per cubic millimeter. In 1956, the patient began to complain of a lasting pain in the right hypochondrlum. No lesion has been found to explain it, and the general condition of the patient has remained satisfactory since then. Briefly, this is an acquired hemolytic anemia with persistent leukopenia. The beginning of the disease dates back to 12 years ago and seems to be related to an acute infection of undetermined etiology. From the serologic point of view, this case is remarkable because of the persistence of the polyagglutinability phenomenon, observed since 1950. Transfusions of washed erythrocytes have been given with success, washed cells being used in order not to give the patient the substance which is present in normal plasma and has the power of agglutinating his own red blood cells. Corticoid therapy has been effective and has made transfusions unnecessary for over two years. From www.bloodjournal.org by guest on December 22, 2014.
