Delayed hemolytic transfusion reaction case study

  • 30.08.2019
The frequency of unexpected studies in blood donors and transfusion candidates in Korea. The anamnestic antibody response resulting from secondary antigen exposure decline, sickle cell patients often receive chronic transfusions frequently leading to alloimmunization. Seoul: Korea Medical Publishing Co; Most blood-group reactions including with a subsequent case in antibody concentrations can lead to unexpected antibody. Majestic wines annual report 2019 feel that I have largely expanded my literary to data collection of our study in any hemolytic, prepared to teach high school students their required literature.

We report on a case demonstrating that DHTR may occur as a result of PS exposure on antigen-matched RBC, resulting in macrophage clearance and hemolysis without detection of autoantibodies or alloantibodies. Red blood cell transfusion continues to play a vital role in sickle cell disease SCD management.

Although the risks of transmissible infectious agents continue to decline, sickle cell patients often receive chronic transfusions frequently leading to alloimmunization. Delayed hemolytic transfusion reaction DHTR is a possible, life-threatening, adverse effect of a blood transfusion due to recipient RBC autoantibodies or alloantibodies. Phosphatidylserine PS is a phospholipid at the extracellular face of the RBC membrane and is associated with the macrophage clearance of sickled erythrocytes.

In several ways this abnormality could contribute to the pathophysiology of sickle cell anemia. Studies have shown that exposure of PS on RBC membrane may promote blood coagulation and could also contribute to observed increases in adhesion of sickle erythrocytes to endothelial cells, and both processes may contribute to microvascular occlusion during sickle cell crisis.

The exposure of PS on sickle cell erythrocytes could also be partly responsible for the decreased RBC survival characteristic of the disorder. Potential consequences of such pathologic PS exposure include an exacerbation of the anemia due to enhanced reticuloendothelial clearance and activation of coagulation cascade. As PS increases RBC adhesion, it facilitates engulfment and macrophage clearance by the reticuloendothelial system. Case Report A year-old male with SCD presented with a history of cough and chest pain lasting 3 days and a hemoglobin Hb of 7.

Despite 2 days of antibiotics, he continued to have increased chest pain, and erythrocytapheresis was instituted. He had no history of alloimmunization and underwent exchange transfusion with 6 units of Rh and Kell antigen-matched packed RBC.

The patient was hospitalized for 3 days, and the total Hb at discharge was Nineteen days following discharge, he was admitted with fever and pain crisis. The total Hb was 6. The Hb electrophoresis showed Hb S The patient was treated with analgesics, intravenous fluids, and folic acid. He was not transfused with any blood components and was discharged 3 days later. He presented 27 days following the last admission with a possible DHTR.

The Hb was 6. Additional serologic testing including direct antiglobulin test DAT and indirect antiglobulin test IAT , which were tested with autologous controls, remained negative. The Transfusion Medicine team was consulted, and it was recommended to withhold any additional transfusions pending investigation. The patient was started on hydroxyurea and Procrit. His lowest Hb was 5. The patient's blood type was O Rh-positive and the preoperative cross matching and antibody screening test turned out to be negative.

Under general anesthesia, right total knee replacement arthroplasty was first performed and after surgery she received 2 units of packed red blood cells RBCs. After transfusion, there was no episode of transfusion reaction. Two weeks after surgery, preoperational test for left total knee replacement indicated that hemoglobin level was On surgery day, she received 0. In the operating room, EKG, noninvasive blood pressure monitoring and a pulse oximetry monitor were placed.

For continuous monitoring of blood pressure and arterial blood gas analysis, 20 G catheter was placed to the left radial artery and central venous catheter was inserted to the internal jugular vein for central venous pressure CVP.

One hour and 20 minutes after the onset of surgery when the total amount of blood loss was estimated more than ml, transfusion of packed RBCs was started. A cross-matching test turned out to be negative again, suitable for transfusion. During transfusion, the patient showed stable vital signs. Five minutes after 1 unit of packed RBCs was transfused, red-colored urine, which was suspected as hemoglobinuria, was observed.

For immediate treatment, fluid was administered while 10 mg furosemide was injected. Then we asked the Department of Laboratory Medicine to conduct ABO-Rh blood typing test of the patient's and the donor's blood, cross-matching, antibody screening test, direct anti-globulin test DAT and indirect anti-globulin test IAT , and urinalysis.

Hereafter, no big blood loss developed and the surgery was completed without further transfusion. Except for the incidence of red-colored urine sustained during surgery, patient's vital signs were stably maintained. At the completion of surgery when her spontaneous respiration and consciousness were confirmed, she was extubated and transported to the recovery room. Red-colored urine sustained even in the recovery room, but the color was waning and the patient's vital signs were normal, so she was referred to a ward.

Post-operative test results showed that the transfused blood and patient's blood were compatible and that antibody screening test result was negative.

Cross-matching turned out to be negative again. Examination of patient's blood tested by an independent laboratory to determine more exact cause revealed that anti-Dia antibody was identified in an unexpected antibody screening test.

Since the next day of surgery, red-colored urine was not observed, which made additional urinalysis unnecessary. Hemoglobin level measured right after surgery was 8. Then, she was discharged without any complications. Discussion Potential adverse effects from blood transfusion involve contamination, acute immunologic hemolytic reaction, delayed extravascular hemolysis, febrile allergic transfusion reaction, erythrocytolysis, etc.

Among these reactions, acute immunologic hemolytic reaction is mainly developed by incompatible blood transfusion of ABO blood group or by unexpected antibody present in the blood. For the patient in this case, cross-matching tests conducted before transfusion and immediately after red-colored urine developed were both negative. The main purposes of cross matching are: 1 to prevent acute hemolytic transfusion reaction due to ABO blood group incompatibility by detecting patient's anti-A and anti-B antibodies against RBCs to be transfused; 2 to prevent acute hemolytic transfusion reaction developed by the response of recipient's unexpected antibody to the counterpart antigen of donor's blood.

What is definitely necessary for the 2nd purpose is the indirect anti-globulin method including an antiglobulin phase. When detecting IgM that reacts even at room temperature such as anti-A or anti-B antibody in 1 , it is possible to identify agglutination reaction by centrifugal sedimentation following after reaction of RBCs and serum at room temperature, which is called "immediate spin phase" or "saline phase".

The main purpose of the immediate spin phase is to prevent ABO blood group incompatibility. When the absence of unexpected antibody in recipient's specimen is confirmed by negative antibody screening result or when an emergency situation makes it impossible to perform a test for incompatibility by unexpected antibody in cross-matching test of anti-globulin method, it takes at least 15 to 30 minutes for the reaction time of serum , it is a routine for RBCs to be taken out only after immediate spin phase [ 7 ].

In the present case, unexpected antibody screening test performed at our hospital was negative while the patient had no abnormal medical history. As bleeding during surgery is regarded as emergency transfusion, cross-matching test was performed only with immediate spin phase and the result turned out to be negative compatible when transfusion was performed.

For the causes of acute hemolytic reaction developed during surgery in the present case, while the results of the tests performed by an independent blood center were unknown, the following three scenarios were to be considered: 1 Drug-induced hemolysis: this assumption is supported by the fact that IAT was positive while antibody screening test was negative. Even though there is no abnormality in previous transfusions, such drugs as acetaminophen, antihistamine, cephalosporin, etc.

Even if a test performed is still negative after exhibition of hemolytic reaction, such possibility cannot be completely excluded.

It is because there are some cases in which the manifestation of unexpected antibodies such as 'kidd' can be identified late or clinical manifestation can be presented at even low potency when the antibody screening test is negative [ 2 , 9 ].

Dib is classified as a high-frequency antigen regardless of ethnicity while the prevalence of Dia differs among races. The Dia antigen is rare in Caucasians, but occurs with high incidence in Asians and American Indians. For Koreans, it is reported that 6. Anti-Dia antibody has relative high positive reaction rate in Koreans [ 3 - 6 ]. It has been reported that anti-Dia antibody was detected in a patient who was given transfusion repeatedly in Korea [ 11 , 12 ], besides incidences of delayed hemolytic transfusion reaction due to anti-Dia antibody [ 13 ].

Because antibody screening panels for an unexpected antibody screening test currently used in Korea are mostly imported abroad, there is a high probability that the Dia antigen is not contained.

Even though anti-Dia antibody is present in patient's serum, it is not detected in unexpected antibody screening test, which keeps transfusion reaction from being prevented. On the basis of the lab results from the independent blood center that the patient was negative for Dia antigen and positive for anti-Dia antibody, we made a diagnosis of acute hemolytic reaction due to anti-Dia antibody.

Considering that she had a history of a surgery previously performed at another hospital when she may have received transfusions and that she was given a transfusion two weeks ago, it is highly likely that anti-Dia antibody was produced by transfusion. Since she had no specific adverse effects of transfusion performed two weeks ago, we assume that she would be first exposed to Dia antigen at the time of transfusion or that there was no side effect because there would be no anti-Dia antigen in the donor's blood even if she had already have anti-Dia antibody.

J Korean Med Sci. For the causes of acute hemolytic reaction developed during surgery in the present case, while the results of the tests performed by an independent blood center were unknown, the following three scenarios were to be considered: 1 Drug-induced hemolysis: this assumption is supported by the fact that IAT was positive while antibody screening test was negative. As bleeding during surgery is regarded as emergency transfusion, cross-matching test was performed only with immediate spin phase and the result turned out to be negative compatible when transfusion was performed. To prevent other transfusion reaction by anti-Dia antibody, addition of Dia positive cells as unexpected antibody screening test is recommended.

He had no history of alloimmunization and underwent exchange transfusion with 6 units of Rh and Kell antigen-matched packed RBC. She had no other specific diseases than osteoporosis. Henry's clinical diagnosis and management by laboratory methods. According to Chadebech and colleagues, recurrence of vaso-occlusive crises and hyperhemolysis may be due to increased PS exposure on patient RBCs, and it is thought that a subsequent transfusion will induce the same consequences, which might further explain the observed exacerbation of hemolysis in SCD patients experiencing a DHTR. In all cases of DHTR, studies have shown that hemolysis of donor RBCs may promote a cascade of events, including the release of free Hb and free radicals, decrease in nitric oxide availability, and release of proinflammatory plasmatic factors, such as proinflammatory cytokines or platelet-activating factor. Follow-up serology at days following the last admission remained negative.

We report a current episode of intraoperative acute hemolytic transfusion reaction due to anti-Dia antibody not detected by preoperative antibody screening test. The negative control consists of the same 7-day-old donor Hb AA RBC mixed with compatible fresh 7-day-old random donor plasma in the same ratio as above. The main purposes of cross matching are: 1 to prevent acute hemolytic transfusion reaction due to ABO blood group incompatibility by detecting patient's anti-A and anti-B antibodies against RBCs to be transfused; 2 to prevent acute hemolytic transfusion reaction developed by the response of recipient's unexpected antibody to the counterpart antigen of donor's blood. On surgery day, she received 0. During transfusion, the patient showed stable vital signs.

When this sample was exposed to additional treatment with calcium ionophore A, an increased PS exposure was measured at As bleeding during surgery is regarded as emergency transfusion, cross-matching test was performed only with immediate spin phase and the result turned out to be negative compatible when transfusion was performed. It has been reported that anti-Dia antibody was detected in a patient who was given transfusion repeatedly in Korea [ 11 , 12 ], besides incidences of delayed hemolytic transfusion reaction due to anti-Dia antibody [ 13 ]. Follow-up serology on the patient days following the episode of hemolysis still demonstrated a negative finding of RBC autoantibodies or alloantibodies and a negative DAT.

Keywords: Anti-Dia antibody, Antibody screening test, Hemolytic transfusion reaction Pre-transfusion test consists of ABO blood grouping, RhD genotyping test, antibody screening test and cross-matching. One hour and 20 minutes after the onset of surgery when the total amount of blood loss was estimated more than ml, transfusion of packed RBCs was started. Therefore, the post-transfusion plasma obtained 19 days after transfusion was used to induce PS exposure on a fresh 7-day-old donor Hb AA RBC confirmed by sickle cell screening. Here we report a case of acute hemolytic transfusion reaction due to Anti-Dia antibody. He was given intravenous fluids and pain medications and was discharged 2 days later for possible sinusitis. The exposure of PS on sickle cell erythrocytes could also be partly responsible for the decreased RBC survival characteristic of the disorder.
