What is the appropriate workup for a patient with a history of Myelodysplastic Syndrome (MDS) and pericardial effusion, now presenting with steadily rising Liver Function Tests (LFTs), thrombocytopenia, and hypoalbuminemia?

From the Guidelines

For a patient with a history of myelodysplastic syndrome (MDS) and pericardial effusion who now presents with steadily rising liver function tests (LFTs), low platelets, and low albumin, I recommend an urgent comprehensive workup to identify the underlying cause of these concerning findings. The workup should include:

• Complete blood count with differential
• Comprehensive metabolic panel
• Coagulation studies (PT/INR, PTT)
• Inflammatory markers (CRP, ESR) Specific liver studies should include:
• Hepatitis viral panel (A, B, C)
• Autoimmune hepatitis markers (ANA, anti-smooth muscle antibody, anti-LKM)
• Iron studies
• Ceruloplasmin Imaging should include:
• Abdominal ultrasound with Doppler to assess for portal vein thrombosis
• CT or MRI of the abdomen with contrast if safe given the platelet count Echocardiography should be repeated to reassess the pericardial effusion and cardiac function. Consider bone marrow biopsy to evaluate for progression of MDS or transformation to acute leukemia, which could explain the worsening cytopenias, as suggested by 1. Liver biopsy may be necessary if the etiology remains unclear after initial testing, though this requires careful consideration of bleeding risk given the thrombocytopenia. These findings could represent disease progression, medication toxicity, infection, or development of a secondary condition such as autoimmune hepatitis or infiltrative disease. Platelet transfusion support may be needed if levels fall below 10,000/μL or below 50,000/μL if invasive procedures are planned, as recommended by 1 and 1. It is also essential to consider the potential impact of iron overload on the patient's condition, as discussed in 1, and assess the need for iron chelation therapy. Given the complexity of MDS management, as outlined in 1, a multidisciplinary approach is crucial to ensure the best possible outcome for the patient.

Patient Workup

The patient has a history of Myelodysplastic Syndrome (MDS) and pericardial effusion, and is now presenting with steadily rising Liver Function Tests (LFTs), low platelets, and low albumin.

Diagnostic Approach

• Echocardiography is essential to define the location and size of the pericardial effusion, as well as to assess for signs of cardiac tamponade, such as chamber collapse, inferior vena cava plethora, and marked respiratory variation in mitral and tricuspid inflow 2.
• The patient's clinical presentation, including hypotension, increased jugular venous pressure, and distant heart sounds (Beck triad), should be evaluated to determine if cardiac tamponade is present 3.
• Laboratory tests, including complete blood count, liver function tests, and coagulation studies, should be performed to evaluate the patient's overall condition and to guide further management.

Management

• Pericardiocentesis is the definitive treatment for cardiac tamponade, and should be performed emergently if the patient is hemodynamically unstable 4.
• Echocardiographic guidance may be used to perform pericardiocentesis, and can help to reduce the risk of complications 5.
• In patients with recurrent pericardial effusion, surgical approaches may be preferable to repeat pericardiocentesis 5.
• The patient's underlying condition, including their history of MDS, should be taken into account when determining the best course of management, and therapeutic measures to address the underlying disease process should be initiated after pericardial drainage is accomplished 4.

Considerations

• The patient's rising LFTs, low platelets, and low albumin should be evaluated in the context of their overall clinical presentation, and may indicate the need for additional diagnostic testing or therapeutic interventions.
• The risk of complications associated with pericardiocentesis, including bleeding and infection, should be carefully considered and mitigated through the use of imaging guidance and other techniques 6.
