How do you approach the management of patients with mildly elevated mPAP (21-24 mmHg) and PVR (2-3 WU) who may be at risk of progression, given the recent changes in the hemodynamic definition of pulmonary hypertension?
The "new" definition of PH with a cutoff of 20 mmHg is a very sensible change, based on the study by Kovacs et al., PMID 19324955, which showed that a mean PAP of 20 mmHg is already two standard deviations above the mean PAP in normals. Thus, the cut off of 20 mmHg makes more sense than 25 mmHg.To a...
What factors should be prioritized when deciding the timing of CIED extraction in patients with high surgical risk or multiple comorbidities?
I'll do my best to respond, though the question isn’t entirely clear to me. If the intent is to determine which patients should be prioritized for CIED extraction, the key consideration is whether the benefits outweigh the risks. The most straightforward case is persistent bacteremia, especially in ...
How do you identify patients with false positive AcHR antibodies?
First of all, of course, one should look for the clinical correlation. Even a weakly positive AchR binding antibody is likely to be "real" (true positive) if accompanied by unequivocal clinical signs of MG, e.g., fatigable ptosis with positive ice pack test, or fatigable bulbar/limb weakness. Ideall...
What is your approach to discordant dsDNA testing, such as positivity to dsDNA by crithidia but negativity to dsDNA by other modalities?
What a great question with many facets. The information I provide is meant to be very practical. These answers are from the viewpoint of a rheumatologist and not an immunologist. I discussed this subject with Dr. Debra Zack, a rheumatologist/immunologist who is an expert with anti-dsDNA, and I had t...
When considering the use of DOACs in APLS, does the number of positive APLS antibodies influence your decision?
The number of antibodies is an important consideration.On the one end of the spectrum, I would not recommend any DOACs in a triple positive APLS (especially with arterial thrombosis). Having said that, I would not change treatment in a triple positive APLS patient if they were started on DOACs in th...
Do you always initiate hypercoagulable work up in a patient with recurrent stroke?
As always, this is a more complex problem than it appears. A history of both prior other thrombosis and family history of thrombosis is essential. Are there good reasons for the stroke and/or has it been worked out in past including carotid disease, atrial fibrillation, underlying malignancy, valvul...
How will you treat a young man with recurrent cryptogenic strokes with no identifiable cause, with MTHFR A1298C homozygous mutation and normal homocysteine level?
The genetic variant you report seems to be a SNP that, while it has been reported to be statistically associated with various diseases in GWAS studies, is not pathogenic. SNPs that are significant in GWAS studies have very small effect sizes that can be measured when considered in thousands of peopl...
Can lupus anticoagulant be positive despite a normal aPTT?
aPTT is one of the assays that may be abnormal in the presence of lupus anticoagulant, but not always. Usually, when screening for lupus anticoagulant, there will be a "special" aPTT assay used that is a bit more sensitive to detect lupus anticoagulant. There are several different aPTT-based assays ...
How do you determine if pulmonary hypertension is disproportionate to the severity of lung disease?
This is a question we faced on a daily basis in our PH clinic. Patients with parenchymal lung disease like COPD or ILD would get an echocardiogram that showed an elevated RVSP and/or RV dilation/dysfunction and will be referred to our clinic for PH evaluation. Alternatively, the patient already unde...
Would you check ANCA titers in a patient with a history of PR-3-ANCA glomerulonephritis in remission and a stable creatinine but with recurrent microscopic hematuria?
Not sure there is an easy answer to this. A patient in remission should not get a recurrence of glomerular hematuria unless the disease is active. A new onset glomerular hematuria would certainly make me worried about a relapse, some of which may be subtle, indicating "grumbling disease". The data o...
