The aim of this study was to describe inflammatory side effects in patients treated with BRAF and MEK inhibitors at a single tertiary care institution. This was a retrospective chart review of patients prescribed single-agent or combination BRAF and MEK inhibitors from January 2010 until May 2015. The primary outcome was the presence of inflammatory side effects. Among 124 patients, 56.4% were male, the median age was 59 years, and most (91.1%) were treated for metastatic melanoma. Most patients (74.2%) developed inflammatory side effects, some with multiple occurrences, for a total of 211 occurrences. The overall prevalence of inflammatory side effects did not differ across therapies. In a subanalysis, patients treated with both single-agent and combination therapies were more likely to experience an inflammatory side effect on single-agent therapy (P = 0.0126 for BRAF inhibitor, P = 0.0833 for MEK inhibitor). The most common inflammatory side effects for the entire cohort included arthralgias/myalgias (32.9%), nonacneiform rash (28.0%), pyrexia (25.5%), and erythema nodosum (11.2%), although side effects differed across the class of therapy. Corticosteroids were initiated in 73 side effect instances among 47 patients. Drug interruption or dose reduction was reported in 78 side effect instances in 50 patients. Fifteen side effect instances led to treatment termination. There is a high prevalence of inflammatory side effects encompassing all organ systems in patients treated with BRAF and MEK inhibitors. There is no significant difference in the prevalence of inflammatory side effects in patients treated with single-agent versus combination therapies, however, side effect profile differs across agents.
This study compared macular capillary parameters between healthy black and white subjects using optical coherence tomography angiography (OCTA). We measured vessel density (VD) of superficial (SCP), intermediate (ICP), and deep (DCP) capillary plexuses and choriocapillaris blood flow area (BFA) of the fovea, parafovea and total 3 mm-diameter circular area centered on the fovea, as well as the foveal avascular zone (FAZ) parameters, controlling for axial length. Black subjects had lower foveal and parafoveal VD in the SCP (p = 0.043 and p = 0.014) and the ICP (p = 0.014 and p = 0.002). In the DCP, black subjects had a trend toward lower foveal and parafoveal VD. Black subjects had decreased choriocapillaris BFA in the total 3 mm area (p = 0.011) and the parafovea (p = 0.033), larger FAZ area (p = 0.006) and perimeter (p = 0.014), and a higher capillary density in a 300 μm wide region around the FAZ (FD-300) (p = 0.001). There was no significant difference in FAZ acircularity index. To our knowledge, this is the first report analyzing the three distinct retinal capillary plexuses and identifying differing baseline VD, choriocapillaris and FAZ parameters in healthy young black compared to white subjects. Larger studies are needed to validate these findings and better understand racial differences in vulnerability to ocular diseases.
Chimeric antigen receptor (CAR) T-cell therapy has become a novel approach in the treatment of many hematologic malignancies. However, ocular adverse effects have not been well described. This report presents a case of a pediatric patient with relapsed B-cell acute lymphoblastic leukemia with ocular involvement treated with CAR T-cell therapy who developed an exudative retinal detachment likely secondary to an inflammatory response to CAR T-cell therapy.
