Plasma concentrations of the acute phase proteins (APP), C-reactive protein (CRP) and haptoglobin (Hp), increased markedly following experimental infection of dogs with Trypanosoma brucei. The highest concentrations of CRP were observed immediately after peaks of parasitaemia. Treatment with curative doses of the trypanocidal drug suramin caused a rapid decrease in CRP. Relapse infections after subcurative treatment were followed by a reappearance of high plasma CRP concentrations. Haptoglobin remained elevated during the course of the disease. Curative treatment with suramin caused a gradual but slow decrease in Hp while subcurative treatment caused no significant changes. Thus, the estimation of CRP was useful in determining the presence of active infection and the success of chemotherapy. High Hp levels in severely anaemic dogs indicated that intravascular haemolysis does not contribute significantly to the anaemia associated with T. brucei infections in dogs. These conclusions need confirmation from a larger experiment.

In various anaemias the values of 8 acute phase factors were determined simultaneously before and at the end of treatment: seromucoid, sialic acid, acid alpha 1-glycoprotein, alpha 1-antitrypsin, haptoglobin, ceruloplasmin, transferrin and fibrinogen. In iron-deficiency anaemia without coexistent inflammatory changes in organs the levels of 4 proteins--seromucoid, alpha 1-antitrypsin, ceruloplasmin and transferrin, were consistently raised. In iron-deficiency anemia with concomitant infection 4 proteins also were increased, but in place of alpha 1-antitrypsin the haptoglobin level was raised. In megaloblastic anaemia the ceruloplasmin level was increased, and in haemolytic anaemia one factor--sialic acid--was decreased. At the end of treatment the concentrations of certain proteins were changed depending on their specific role in various forms of anaemia and on various additional factors. In iron-deficiency anaemia without coexistent infection the concentration of seromucoid was decreased, and in this anaemia with coexistent infection alpha 1-antitrypsin, haptoglobin, and fibrinogen levels were raised, in haemolytic anaemia only fibrinogen was increased, and megaloblastic anaemia was associated with raised seromucoid level. The therapeutic result was good in all these anaemias with the exception of iron-deficiency anaemia associated with infection in which it was less propitious.

An elderly case of systemic lupus erythematosus (SLE) with suspected hemolytic anemia was experienced. A 70 year-old female was admitted to our hospital on December 31 with complaints of herpetic eruption. She complained of arthralgia since 3 month prior to her admission. The positive findings on examination were skin eruption in the left chest, a systolic heart murmur and a palpable elastic hard liver. Laboratory data showed raised erythrocyte sedimentation rate of 149 mm per hour, decreased Hb (10.1 g/dl), decreased hematocrit (30.0%), increased reticulocytes (33%1000), decreased thrombocytes (73,000/mm3), increased gamma-globulin (33%) and positive rheumatoid factor. During admission, she developed anemia. A stool test for occult blood was negative. The haptoglobin was 38.8 mg/dl and bone marrow aspiration showed increased erythropoiesis, suggesting features of immune hemolytic anemia, except she was negative on Coomb'test. Eye fundi were similar to case of typical bleeding observed in SLE. Concerning immunological findings, the antinuclear factor was x 1280 and the anti-dsDNA antibody was x 80, on which a diagnosis of SLE was based. She experienced numbness of the left arm and developed left hemiparesis 2 days later. Therapy with 15 mg/day prednisone obtained a good response and anemia, abnormal immunological findings and hemiparesis disappeared.

We treated a 29-year-old male patient with pseudohypoparathyroidism type I, who showed a slight increase in serum indirect bilirubin without any signs of liver dysfunction. Serum levels of total, direct and indirect bilirubins were 2.4, 0.7 and 1.7mg/dl, respectively (normal ranges: 0.2-0.8, 0-0.2 and 0.2-0.6mg/dl, respectively). The cause of the increases in serum bilirubin levels was not clear; however, hemolytic anemia, hereditary unconjugated hyperbilirubinemia or ineffective erythropoiesis were ruled out as causes for the increase, since 1) his serum level of haptoglobin was normal, 2) increase in serum level of indirect bilirubin 120 minutes after the infusion of 50mg nicotinic acid was within the normal range, and 3) severe anemia was not observed. Osmotic fragility of his circulating red blood cells was also within normal range. Three other patients with pseudohypoparathyroidism visiting our clinic also showed slightly high levels of serum indirect bilirubin, although four outpatients with idiopathic hypoparathyroidism showed no such abnormality. Abnormality in the responsiveness to parathyroid hormone and/or to that in the cyclic AMP productivity in this disease may cause the increase in the circulating unconjugated bilirubin.

Four patients with primary pulmonary hypertension, microangiopathic hemolysis, and thrombocytopenia were seen at the Charleston (WVa) Area Medical Center between 1983 and 1988. Characteristic laboratory and clinical features of these patients were the following: mild anemia, reticulocytosis, low serum haptoglobin value, microangiopathic red blood cell changes on peripheral blood smear, mild to moderate thrombocytopenia, normal clotting studies (ie, prothrombin time, partial thromboplastin time, fibrinogen), negative direct Coombs' test, negative glucose water test, normal serum urea nitrogen and creatinine levels, lack of improvement of hemolysis and thrombocytopenia in response to vasodilators or calcium channel blockers, and severe plexiform lesions in the pulmonary vasculature with fibrin deposition at autopsy. The hemolysis and thrombocytopenia probably developed as a result of flow through the fibrin deposition in the plexiform lesions in the pulmonary circulation and subsequent shearing of red blood cells and platelets.

Hemophiliacs often have mild anemia, and hemolysis has been suggested as the likely mechanism on the basis of the reduced serum haptoglobin values frequently observed in these patients. It has been suggested that hypohaptoglobinemia results from isohemagglutinins or other contaminating proteins in the infused factor concentrates. The advent and increased utilization of Factor VIII concentrates that are highly purified by use of monoclonal antibodies have provided the opportunity to study whether proteins other than Factor VIII contained in the concentrate induce hemolysis. Of 49 consecutively studied Factor VIII-deficient hemophiliacs, 19 (39%) had a reduced serum haptoglobin level (less than 27 mg/dl). In particular, 16 of 35 (46%) of patients receiving only monoclonally purified Factor VIII products (Monoclate or Hemofil-M) had a reduced serum haptoglobin value. Haptoglobin measurements were variable on repeat measurement in 8 patients. Haptoglobin levels did not correlate with type or severity of hemophilia, hemoglobin value, or alterations in liver function. Low serum haptoglobin values were also observed in children with leukemia, without apparent hemolysis, who had extensive cutaneous hemorrhage associated with thrombocytopenia. We propose that reduced serum haptoglobin values in hemophiliacs do not result from immune-mediated hemolysis due to contaminating proteins in the concentrate. Moreover, hypohaptoglobinemia may not be due to hemolysis at all but may instead result from dissolution of hematomas and other foci of internal hemorrhage.

The relationship between intravascular hemolysis induced by aortic valve prosteses and patient status/left ventricular (LV) function (radionuclide cardiography) was examined in 63 patients of 65 who were alive ten to seventeen years after valve replacement (1965-1973) for aortic stenosis. Serum-lactic dehydrogenase (LDH) exceeded upper reference limit in 62 patients and S-haptoglobin (HAPTO) was reduced in 62. One patient with normal LDH had reduced HAPTO and elevated plasma-hemoglobin. Anemia was noted in 4 patients (6%). S-LDH was higher in men than in women (p less than 0.05), in patients with increased ECG hypertrophy score than in those with a normal score (p less than 0.05), in patients with NYHA class II-III than in those with class I (p less than 0.05), in patients with abnormal LV function than in those with a normal radionuclide study (p less than 0.05), in patients with a pathologic Q wave in the ECG than in those without (p less than 0.05), and in patients with a Starr Edwards cloth-covered (SECC) prosthesis than in those with other types (p = 0.07). ECG hypertrophy score correlated directly with LDH (r = 0.33, p = 0.008) and inversely with LV ejection fraction (r = -0.57, p less than 0.0001), peak ejection rate (r = -0.47, p less than 0.0001), and peak filling rate (r = -0.41, p less than 0.001). Multiple linear regression analysis revealed that LDH was accounted for by ECG hypertrophy score (p = 0.001), SECC prosthesis (p = 0.04), and male gender (p = 0.05). Hypertrophic malfunctioning left ventricles may be responsible for higher degrees of turbulent flow characteristics in the vicinity of prosthetic valves in the aortic position and, by inference, explain the increased tendency toward hemolysis in these patients.

A 77-year-old man was admitted to our hospital, due to systemic lymph node swelling. Nine months before his admission, he had been given a right hemicolonectomy for a colon cancer, that had been followed by chemotherapy (MMC and Tegafur). Laboratory testing revealed these findings: RBC 217 x 10(4)/mm3, Hb 8.3 g/dl, haptoglobin less than 10 mg/dl, positive Coombs test, cold hemagglutinin titer, 1:512, and polyclonal hyper r-globulinemia. A biopsy of a lymph node specimen exhibited the histological appearance of an IBL-like T-cell lymphoma described by Shimoyama et al. Although treatment with prednisolone was started for autoimmune hemolytic anemia, the patient died of severe anemia two months after the appearance of his lymph node symptoms.

A seven year-old boy with hereditary stomatocytosis complicated with aplastic anemia was reported. He was admitted to our hospital because of pale and general fatigue. On physical examination, he had severe anemia, petechiae, but no hepatosplenomegaly. Peripheral blood cell count revealed pancytopenia; RBC 103 X 10(4)/microliters, Hb 3.5 g/dl, Ret 21%, WBC 1,200/microliters, Pl 1.3 X 10(4)/microliters, and bone marrow revealed markedly hypocellular marrow. Red cell morphology demonstrated stomatocytosis. Red cell life span (51Cr T1/2) was 12 days, Coombs' test and Ham's test were negative. Indirect bilirubin was 1.1 mg/dl and marked decrease of haptoglobin was found. Family studies showed that his father and sister had stomatocytosis on peripheral blood examination, but no anemia. The patient had severe anemia because of complicated aplastic anemia. Congenital stomatocytosis with aplastic anemia is extremely rare. The authors are interested in a possible relationship between hereditary stomatocytosis and aplastic anemia although the precise mechanism remains to be elucidated.

Haematological abnormalities are frequently found in heavy-drinking chronic alcoholics, but anaemia is generally a rare complication. When present, haemolysis is considered to be one of the most common causes. However, little is known about mild haemolysis without anaemia. The present report on eighteen male chronic alcoholics with a recent heavy debauche but without signs of severe liver disease gave support for the occurrence of a reversible low-degree haemolysis without concomitant gross changes of the erythrocytes. Thus the bone marrow showed an increased erythropoiesis in the absence of iron deficiency and known blood losses. Further, increased reticulocyte counts and low levels of haemopexin were noted in the early abstinence. Finally, during the withdrawal phase haptoglobin and haemopexin increased concomitantly with diminishing values of unconjugated bilirubin. The most likely cause of the proposed diminished red cell survival before the withdrawal is supposed to be a reduced membrane stability.
