Correlation and Regression Analysis Applied for Types and Number of Blood Transfusions Versus Transfusions Induced ADR Among Pediatric Haemato-Oncology and Thalassemia Patients

Abstract

Introduction: Blood transfusion is a remedial intercession and a fundamental fragment of Current medical services framework.

In any case, the dangers of non-irresistible difficulties have gotten more obvious. These nonirresistible complexities called as adverse transfusion reactions (ATRs) can either be intense in nature or follow a postponed course.

Introduction

Blood transfusion is a remedial intercession and a fundamental fragment of Current medical services framework. As indicated by the WHO the bonding is an action of moving blood or blood-items taken from a giver into the vasculature and in this manner the flowing blood of the recipient, done by embeddings an IV Needle/Catheter in the patient and followed by use of blood or the blood-items.¹

In any case, the dangers of non-irresistible difficulties have gotten more obvious. These non-irresistible complexities called as adverse transfusion reactions (ATRs) can either be intense in nature or follow a postponed course.²

Transfusion reaction is any unanticipated impact that happens in a patient during or subsequent to accepting blood and the blood-items. These can be arranged as intense transfusion responses, happening inside 24 hours of transfusion and deferred bonding responses happens inside the space of days or long periods of bonding. Intense and moderate responses can be additionally classified as insusceptible interceded and non-immune intervened.³,⁹

Different types of ADR (Adverse drug reaction) were observed after the transfusion of blood and its components. The observed ADR were fever, chills, urticarial, hepatomegaly due to the transfusion of whole blood, PCV, and Fresh-Frozen Plasma. As the number of transfusion increases the incidence of ADR occurrence is also increased.⁸

Information on conceivable unwanted impacts will be valuable to forestall their event and help in clinical administration. Hemovigilance is intended to identify and dissect all untoward impacts of blood-bonding to address their motivation and forestall the Repeat⁴

Methodology and Eligibility Criteria

The project was carried-out in Department of Pediatric Oncology & Thalassemia unit. The population required for the study includes patients undergoing blood transfusions. The study design selected was prospective and observational design. A period of 6 months was determined for the purpose of data collection and observation of adverse reactions.

In the study, patients of both genders (male and female) of ages less than equal to 18 years were considered. Also, thalassemia patients and patients with any type of cancer who were ready to accept the protocols were included. Patients enrolled in other study and with any solid tumor were excluded (Refer Figure 1).

The mean and standard deviation for the Types of ADR and types of transfusion was observed to be 1.32 ± 1.554 and 3.56 ± 1.028 respectively.

In Pearson correlation, types of ADR and types of transfusions are positively correlated but it is not statistically significant because the P value is more than .05 (Refer Tables 5 and 6).

The mean and standard deviation for the Types of ADR and number of transfusion per person was observed to be 1.32 ± 1.554 and 1.00 ± 1.760 respectively.

In Pearson correlation, types of ADR and number of transfusions are positively correlated and statistically significant with P value less than .05.

The chart represents that the rate of incidence of ADR is increased as the number of transfusions increase (Refer Table 7).

Correlation of Types of ADR and Number of Transfusion. among Pediatric Haemato-Oncology and Thalassemia Patients

The chance of an ADR occurrence with every transfusion is 0.4. The P value is less than .05 so it is statically significant. It is positively correlated, having a high impact on the number of transfusion and rate of incidence of ADR.

The R value of multiple transfusion with ADR occurrence (.4) gives a significant result at P value less than .05 so it reveals the correlation between the respective variables.

The result of regression analysis shows that every unit increases in blood transfusions to the patient occurrence of ADR significantly increases by 0.478 times. Thus, 22.8% of variance (adjusted R² = .228).

The ADR can be explained by single blood transfusion at P value less than .05. Thus, the results are significantly significant (53.96%) didn’t suffer from any adverse reaction (Refer Table 8).

Discussion

This study demonstrates the correlation and regression for types and number of Blood transfusions versus transfusions induced ADR among pediatric haemato-oncology and thalassemia patients at the tertiary care Hospital which was an Prospective and observational study. This study was conducted especially in pediatric population (0-18 years) of both in male and female.

Stainsby et al,¹ it was observed 153 (47.7%) subjects of male patients were included and 163 (50.8%) subjects of female patients were included. In current study, 38 (60.48%) subjects of male patients were included and 25 (39.38%) subjects of female patients were included.

Present findings indicating that total of 83 units, out of which 61 units of PCV (73.49%), 6 units of platelets (7.22%), 14 units of Whole Blood (16.86%), 1 units of Fresh Frozen Plasma (1.20%), and 1 units of RBC (1.20%) was transfused.

In study conducted by Tushar it was observed that a total no. of 8121 units of whole blood and components were given. These comprised whole blood (5535 [68.15%]), packed red blood cells (901 [11.09%]), Fresh-Frozen-plasma (1180 [14.5%]), and Platelets (505 [6.21%]).⁶

Howsoever, it was seen in our study that out of 63 patients enrolled, 11 patients had from hematomegaly (17.46%), 9 patients had fever (14.28%), 8 patients had chills (12.69%), 1 patient had rashes (1.58%), and 34 patients didn’t suffer from any adverse reactions. Therefore in a study it was observed that almost half of the patients (47.6%) suffered from ADR and these patients only required symptomatic treatment or no treatment.

In a similar report by Bhattacharya, Negi G et al,⁴ event of adverse transfusion reaction was 0.18% (105 reactions out of [56 503 units] of blood and it’s segment transfused).

Additionally in a report by Negi et al, Blood-transfusion security: Investigation of unfriendly responses at the blood donation center of a tertiary consideration place (38 013 units) of blood and it’s segments that had been given, 101 (0.2%) cases had an ATR. The most notable reaction was negatively powerless—34/101 (33.6%) followed by Febrile—26/101 (25.7%). Various reactions included bonding related exceptional Lung-injury in-6/101 (5.9%) cases, and immune reactions were found in 19/101 (18.8%) cases.⁵

In the current study there is a positive and significant correlation with types of ADR and number of transfusion. Also there is a positive correlation with the type of ADR and types of transfusion but it is not statistically significant.

Similarly, in a study conducted by Hendrickson and Hillyer, it was observed that the most Serious ADR was caused because of the Acute transfusion reactions or events. Also there was a significant correlation with types of ADR and number of transfusion. It also indicates a high impact on number of transfusion and rate of incidence of ADR. Each blood item that was transfused conveys a little danger of an intense or late unfavorable impact. The most well-known prompt ADR to transfusion are fever, chills and urticaria. In specific instances of gentle urticarial responses or the presence of rehashed chill-fever responses in duplicate transfused patients.^7,10

Conclusion

This study conducted on the detection of adverse reactions in patients receiving blood transfusions concludes that the occurrence of adverse reactions during or after the blood transfusion was caused by numerous reasons and the main reason for most of the reactions seen was directly related to the number of blood or its products being transfused. . .

While a Blood transfusion is given for unavoidable situation the important factors to be kept under consideration are ADR following transfusion which can be the common complication observed. The study also concludes that the rate of incidence of ADR is increased significantly as the number of transfusion increases.
