What are your management strategies for acute kidney injury attributed to pembrolizumab in patients with a kidney biopsy showing predominately acute tubular injury?
If ATN is indeed the predominant lesion, then I’d work up for usual causes (meds, infection, hemodynamic shifts, etc.). I would not advise holding pembrolizumab in this case unless there are other indications to do so.
Do you pursue a skin biopsy or kidney biopsy in patients whom you suspect have X-linked Alport syndrome?
The approach to the diagnosis of Alport syndrome has changed over the past decade with heavier reliance on molecular genetic testing sometimes prior to or in lieu of tissue diagnosis, however, this is dependent upon many factors including insurance coverage and availability of electron microscopy. G...
When do you check macroprolactin in the evaluation of hyperprolactinemia?
Macroprolactin is usually biologically inactive so if a patient has high prolactin without any symptoms, I would check macroprolactin.
What is your approach to a patient with IgG4RD with past pulmonary involvement (biopsy proven) managed with steroids alone, now with new hematuria/proteinuria, but stable renal function?
Significant hematuria is not a typical feature of IgG4-related kidney disease. IgG4-RKD most commonly presents as tubulointerstitial nephritis (TIN), which presents as mild, non-nephrotic range proteinuria. In fact, urinalysis in the context of TIN is often normal, as the proteinuria is largely non-...
What additional testing besides LAC/APLS, factor V Leiden, prothrombin gene mutation, JAK 2 do you draw for unprovoked cerebral venous sinus thrombosis?
Cerebral venous sinus thromboses (CVST) are often put into the category of "thromboses of unusual sites,"--as opposed to the more common lower extremity thromboses or pulmonary emboli.Provoked causes of CVST include pregnancy or exogenous estrogen use, infection of the head/neck or CNS, head trauma,...
How do you approach treating patients with lupus profundus?
For lupus profundus/lupus panniculitis, I would first confirm the diagnosis with a deep punch biopsy or incisional biopsy. The differential for lupus profundus includes factitial panniculitis, traumatic panniculitis, morphea profundus, and subcutaneous panniculitis-like T-cell lymphoma.Once the diag...
How long can you treat dermatomyositis with IVIG?
Typically, in best-case scenarios, you can treat dermatomyositis with IVIG for 1 year, but some patients require it for 18-24 months, and the minority of patients continue to require it over several years. Some patients may only need it until you achieve improvement, especially in some countries whe...
How would you approach a patient with MPO-positive isolated peripheral nerve vasculitis?
AAV can present with a peripheral neuropathy as a first manifestation. The first question we're often facing is whether a biopsy is necessary. If the neuropathy pattern is one of mononeuritis multiplex and there are no atypical features or other atypical serologic findings, I sometimes forego nerve ...
What is the risk of serious bacterial infection in a febrile solid tumor patient who has not yet started cancer-directed therapy and has normal cell counts with no central line?
This depends on the type of the tumor, the location, and the individual circumstances. It may not be wrong in this scenario to draw blood cultures and give a dose of ceftriaxone pending 24-hour results, but this practice may also vary based on these different variables e.g. RMS of paranasal-ear area...
For how long do you treat uncomplicated CRE bacteremia in an immunocompetent patient?
Assuming rapid resolution of the systemic inflammatory response, I generally recommend 7 days of antibiotic administration – and I am not aware of data that this should be prolonged when the pathogen is a CRE. One of the studies listed below [Soto et al] addresses CRE bacteremia and the duration of ...
