Immune checkpoint inhibitors targeting programmed cell death protein 1 and cytotoxic T-lymphocyte associated protein 4 have improved survival in patients with metastatic melanoma, especially in combination (i.e., ipilimumab-nivolumab). Postmarketing surveillance has identified rare but at times life-threatening adverse effects associated with these agents in combination and as monotherapy, which include myocarditis, myositis, myasthenia gravis (MG), and hepatotoxicity. Further evaluation of immune checkpoint therapy-induced MG identified the rapid clinical progression, prolonged treatment/supportive therapy course, and higher frequency of myasthenic crisis in these patients versus those with idiopathic MG. More rapid incorporation of aggressive treatment options (i.e., intravenous immunoglobulin, plasmapheresis) may be necessary in these cases. Anti-striational antibodies are often detected in individuals with myasthenia gravis and concurrent myositis and myocarditis. A high-index of suspicion is necessary to assist with rapid treatment initiation as these patients can rapidly deteriorate into respiratory compromise. A case of a 78-year-old woman with metastatic melanoma status after combination therapy with ipilimumab-nivolumab that developed transaminitis, myositis, myocarditis, and myasthenia gravis (with positive anti-striational antibodies) five days after the first cycle, is presented. Despite high dose intravenous methylprednisolone and intravenous immunoglobulin treatment, she ultimately entered hospice care eight days after hospital admission, 36 days after her first cycle.

Background/purposeThe purpose of this study was to evaluate the effectiveness of supplemental diabetes-related training modalities and volunteer activities in increasing first-year medical students’ knowledge/comfort in providing diabetes self-management education and support (DSMES) to patients.MethodsA group of medical students developed supplemental diabetes-related training/volunteer programs. The training modalities included an optional 7-session interprofessionally taught Diabetes Enrichment Elective and a 3-hour endocrinologist-led training session intended to prepare students for involvement in an inpatient DSMES volunteer program. The volunteer program provided the students with the opportunity to provide DSMES to patients with diabetes admitted to an academic medical center. Those participating in any of the stated programs were compared to those with no such training regarding confidence in providing DSMES using an optional online survey. The results were analyzed by using Mann–Whitney U test and descriptive analyses.ResultsA total of 18 first-year medical students responded to the optional survey with a response rate of ~30% (10 of 33) among participants in any training/volunteer program. First-year medical students who attended any of the offered optional programs had statistically significant higher comfort level in 4 of the 6 areas assessed regarding providing DSMES compared with those with no such training (p<0.05), with medium to large effect size (r=0.48–0.59).ConclusionThis study suggests that the supplemental preclerkship diabetes-specific training modalities/volunteer programs can provide benefit in providing medical students with practical knowledge while improving their confidence in providing DSMES to patients with diabetes.
