Insights

Prognosis for heart transplant recipients experiencing antibody-mediated rejection (AMR) with cardiogenic shock (CS) is poor. Aggressive treatment showed high mortality, with most cases linked to de novo donor-specific antibodies (DSA).

Area of Science:

  • Cardiology
  • Transplantation Immunology

Background:

  • Data on the prognosis of heart allograft antibody-mediated rejection (AMR) complicated by cardiogenic shock (CS) are limited.
  • Antibody-mediated rejection (AMR) is a significant concern following heart transplantation.

Purpose of the Study:

  • To analyze the characteristics, treatment, and outcomes of patients with biopsy-proven AMR and CS.
  • To investigate the prognosis and recurrence of AMR in heart transplant recipients with CS.

Main Methods:

  • Retrospective, single-center observational study.
  • Inclusion criteria: biopsy-proven AMR and CS.
  • Follow-up for graft function, AMR recurrence, and cardiac allograft vasculopathy (CAV) in survivors.

Main Results:

  • Seventeen patients (70% male, median age 56 years) were included; AMR occurred at a median of 21 months post-transplant.
  • Most cases involved de novo class II donor-specific antibodies (DSA); only 2 had prior AMR history.
  • In-hospital and 1-year mortality rates were high (76% and 82%, respectively), despite aggressive immunosuppression.

Conclusions:

  • Cardiogenic shock due to AMR, particularly with de novo class II DSA, carries a poor prognosis.
  • Aggressive conventional immunosuppressive therapies demonstrated limited efficacy in improving survival for these patients.

Antibody Structure

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
The Y-Shaped Structure of Antibodies Consists of Four Polypeptide Chains
Antibodies consist of four polypeptide chains: two identical heavy...

Sign Convention01:30

Sign Convention

When analyzing a beam subjected to various loads, it is crucial to understand the internal forces and moments generated within the structure. These internal forces can be broadly classified into normal forces, shear forces, and bending moments. To determine these forces and moments, we use the method of sections and apply a specific sign convention based on their direction and the side of the section being analyzed.
The normal force acts perpendicular to the beam's cross-section and can...

Shock Waves01:16

Shock Waves

While deriving the Doppler formula for the observed frequency of a sound wave, it is assumed that the speed of sound in the medium is greater than the source's speed through it. When this condition is breached, a shock wave occurs.
When the source's speed approaches the speed of sound, constructive interference between successive wavefronts emitted by the source occurs immediately behind it. Initially, scientists believed that this constructive interference would result in such high...

Enolate Mechanism Conventions01:15

Enolate Mechanism Conventions

When a carbonyl compound is treated with a strong base, the α position gets deprotonated to give a resonance-stabilized intermediate called an enolate. Enolates are ambident nucleophiles because they possess two nucleophilic sites that can attack an electrophile owing to the delocalization of the negative charge between the α carbon and oxygen atoms. When the oxygen atom attacks an electrophile, it is called O-attack, whereas electrophilic attack via the α carbon is known as...

Hypothesis: Accept or Fail to Reject?01:17

Hypothesis: Accept or Fail to Reject?

The outcome of any hypothesis testing leads to rejecting or not rejecting the null hypothesis. This decision is taken based on the analysis of the data, an appropriate test statistic, an appropriate confidence level, the critical values, and P-values. However, when the evidence suggests that the null hypothesis cannot be rejected, is it right to say, 'Accept' the null hypothesis?
There are two ways to indicate that the null hypothesis is not rejected. 'Accept' the null...

Quantifying and Rejecting Outliers: The Grubbs Test01:02

Quantifying and Rejecting Outliers: The Grubbs Test

Sometimes, a data set can have a recorded numerical observation that greatly  deviates from the rest of the data. Assuming that the data is normally distributed, a statistical method called the Grubbs test can be used to determine whether the observation is truly an outlier.  To perform a two-tailed Grubbs test, first, calculate the absolute difference between the outlier and the mean. Then, calculate the ratio between this difference and the standard deviation of the sample. This...
