For patients with microcytosis MCV 75-79 and normal Hb, low TIBC, and normal ferritin do you always rule out thalassemia?
Microcytosis is typical in thalassemia. With a normal ferritin and hemoglobin concentration, I would start screening by measuring HPLC, HbA2 levels that are high in beta-thalassemia carriers. (HbA2 can be normal with “mild” thalassemia alleles and for several other reasons.) Microcytosis without iro...
What is the target ferritin level for patients with hereditary hemochromatosis and signs of end-organ damage?
I believe the best marker to guide phlebotomy therapy for iron overload is the serum ferritin concentration. I use a target ferritin level of approximately 50 ng/ml. However, one could justify a ferritin level of <200 ng/ml from the literature of serum ferritin compared to body iron stores in HFE he...
Do you continue antiplatelet/anticoagulant therapy in patients with hemodynamically stable diverticular bleeding to improve localization and treatment of source of bleeding?
Usually the decision to stop antiplatelet/anticoagulant therapy is dependent on the indication for starting the therapy, the severity of the bleeding and hemodynamic status of the patient. Based on the current ACG guidelines, it is ok to continue antiplatelet/anticoagulant therapy for hemodynamicall...
Do you recommend careful correction of serum sodium to avoid osmotic demyelination syndrome in patients who are found to have isoosmolar hyponatremia in the setting of an elevated BUN level?
Urea is an ineffective osm and so if the blood is "isoosmolar" in the setting of hyponatremia but is isoosmolar because of an elevated BUN it may be isoosmolar numerically but not physiologically. I would ignore the BUN in making my decision. I would not ignore the BG though if it were elevated.
Do you routinely order a pre-operative TTE in patients with apparently compensated CHF, but who have not had an echocardiogram in some time?
In a patient with compensated CHF (with stable symptoms), I do not routinely order pre-operative echocardiograms for evaluation of ejection fraction. There are some situations in which it may be helpful for perioperative risk assessment, counseling, and management.The 2024 ACC/AHA (American College ...
How do you decide between opting for semi-elective outpatient versus inpatient TAVR for patients with severe critical AS?
Most patients undergo semi-elective procedures, which are more favorable for hospital reimbursement and reduce the risk of acute kidney injury. However, in a small subset of patients (<20%) with critical aortic stenosis (AS) and severe symptoms, particularly syncope, inpatient management is required...
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...
