Is there a role for nitazoxanide for treatment of norovirus gastroenteritis in immunocompromised patients?
There is no good-quality evidence supporting a role for nitazoxanide for treatment of norovirus gastroenteritis in immunocompromised patients. The efficacy of nitazoxanide in viral gastroenteritis is supported by a small manufacturer-sponsored randomized, double-blind trial in non-immunocompromised ...
If a patient who has tolerated allopurinol for a prolonged period of time is subsequently found to be positive for the HLA-B*58:01 gene, how would you manage urate-lowering therapy thereafter?
There is a strong association between the presence of the HLA-B*58:01 allele and allopurinol-related severe cutaneous adverse reactions (SCAR* - Stevens-Johnson Syndrome, Toxic Epidermal Necrolysis or Severe Hypersensitivity Syndrome). This association was demonstrated in a Taiwanese study by Hung e...
Do you have safety concerns when prescribing GLP-1 medications in patients on corticosteroids or immunosuppressive therapy?
I think we need to be particularly careful when co-prescribing with systemic corticosteroids because of the risk of sarcopenia. We know that rapid weight loss is accompanied not only by a loss of fat tissue but also of muscle. Corticosteroids can also have myotoxicity and cause muscle atrophy. I the...
Are there particular subsets of AAV patients in which avacopan is more effective?
The following answer was jointly drafted by Dr. Peter Merkel and Dr. David Jayne:Patients in the ADVOCATE trial were stratified at entry according to time of diagnosis (new/relapsing), diagnosis (GPA/MPA), ANCA serotype (PR3/MPO), and background immunosuppressive (cyclophosphamide/rituximab) with re...
What approaches can we take to initiate therapy and improve survival rates in patients with HLH?
At our institution, we have comprised a multidisciplinary team to help treat these patients. The team or "HLH task force" as we like to call ourselves is comprised of a clinical immunologist, rheumatologist, dermatologist, critical care physician, hepatologist, BMT attending/hematologist, infectious...
What is your approach to managing sclerosing mesenteritis (mesenteric panniculitis)?
I have seen and followed dozens of patients with this diagnosis. As noted above, it is important foremost to be sure of the diagnosis. Mesenteric panniculitis can be part of the IgG4 associated spectrum and so a biopsy is useful if it can be done safely. The other disease in the differential is carc...
What baseline work-up or "staging" do you do in patients with a new diagnosis of Sjogren's (i.e., PFT, cryoglobulins, complement, RF, UA)?
The baseline workup I like to do in patients newly diagnosed with Sjogren's are the following lab tests with rationale: ANA (almost all patients have a high titer ANA that is positive - typically it is a speckled pattern Extractable nuclear antigen (ENA) testing looking for SSA (anti-Ro antibody) +/...
Would the need for infliximab/MTX/nonsteroidals to control initial irAE affect your decision to rechallenge these patients with ICI?
Infliximab and methotrexate are generally used in irAE grades 3 or 4, or in grade 2 irAEs that are refractory to initial treatment with steroids. Methotrexate is typically used for irAEs of the musculoskeletal system, such as inflammatory arthritis or myositis. Infliximab tends to be used in the set...
In a patient with persistent symptoms of Lyme arthritis after initial treatment course with oral antibiotics, do you prefer a second course of oral antibiotics or do you frequently offer a course of IV ceftriaxone?
Patients diagnosed with Lyme arthritis should receive a 28-day course of oral antibiotics, preferably doxycycline. If patients achieve at least a partial response, a second course of oral antibiotics may be given. However, in patients with minimal to no response following the initial course of oral ...
Has the MAJESTY trial changed your approach to the rituximab versus obinutuzumab choice in a patient with newly diagnosed primary membranous nephropathy and nephrotic syndrome?
The Bottom Line: Recent landmark trials—MENTOR and MAJESTY—confirm that anti-CD20 therapies are superior to calcineurin inhibitors (CNIs) for the treatment of MN.Key Trial DataMENTOR: Demonstrated that RTX was noninferior to cyclosporine at 12 months, and decisively superior by 24 months (60% vs. 20...
