Intravenous immunoglobulin therapy and plasma exchange through transfusion of fresh frozen plasma are therapeutic options for patients with refractory pemphigus vulgaris. Passive acquisition of various clinically important antibodies through these therapies can occur, leading to false serology and negatively affecting patients' clinical care. It is recommended that dermatologists recognize the possibility of these phenomena and interpret them appropriately. Here, we report false-positive serology following intravenous immunoglobulin therapy and plasma exchange through transfusion of fresh frozen plasma in a patient with refractory pemphigus vulgaris. We also discuss the measure for misinterpretation and unnecessary clinical intervention.

Context: Acute myocarditis is a rare but potentially life-threatening condition in infants and children. While immunosuppressive agents have shown limited effectiveness, intravenous immunoglobulin (IVIg) holds promise as a treatment option.
Objective: To study the efficacy and safety of intravenous immunoglobulin (IVIg) in treating acute viral myocarditis in children.
Efficacy and Safety of a Desensitization Treatment With Rituximab and Immunoglobulin in Hyperimmunized Patients Awaiting a Cadaveric Kidney Transplantation.

Background: Patients on a kidney transplant waiting list with antibodies against more than 80% of a panel reactive antibody (PRA) are difficult to transplant, even with national or regional programs. Desensitization treatment with high-dose intravenous immunoglobulin and rituximab could be offered to patients with a long waiting time for a cadaveric donor to improve their odds of finding a kidney.
Methods: This was a retrospective, single-center study including all hyperimmunized patients on the waiting list for a cadaveric kidney donor who received a desensitization treatment between 2010 and 2020.

Pemphigus vulgaris is a severe and often therapy-resistant bullous autoimmune disease. Standard therapy with steroids often administered together with another immunosuppressant does not respond in all patients or may not be a good therapeutic option in patients with severe underlying diseases. Intravenous immunoglobulins (IVIgs) represent a treatment alternative, often showing a rapid response which allows one to reduce concomitant immunosuppression.

Immune checkpoint inhibitors (ICIs), such as pembrolizumab, have revolutionized cancer treatment by enhancing the immune system's response to malignancies. However, these therapies are associated with immune-related adverse events (irAEs), including neuromuscular complications such as myasthenia gravis, myositis, and myocarditis. We describe two male patients, aged 67 and 68, with small cell and non-small cell lung cancers, who developed progressive neuromuscular symptoms, including ptosis, diplopia, and generalized weakness, after receiving pembrolizumab.

Current treatments for fundus disorders, such as intravitreal injections, pose risks, including infection and retinal detachment, and are limited in their ability to deliver macromolecular drugs across the blood‒retinal barrier. Although non-invasive methods are safer, their delivery efficiency remains suboptimal (<5%). We have developed a wearable electrodriven switch (WES) that improves the non-invasive delivery of macromolecules to the fundus.
