Case Reports
[Subendocardial injury with no evidence of atherosclerosis associated with obinutuzumab infusion].
Obinutuzumab is a fully humanized monoclonal antibody against CD20 used in the treatment of chronic lymphocytic leukemia. Fatal cardiovascular events have been described, but only in patients with known cardiovascular records. We report the case of an adult male with a high-risk chronic lymphocytic leukemia who developed subendocardial injury, with no evidence of coronary atherosclerosis, during the first administration of obinutuzumab.

Rathke's cleft cyst (RCC) are a slow-growing, benign, cystic lesions that arises from the remnants of the primitive ectoderm and Rathke's pouch. They present a common origin with pituitary adenomas (PA), however, the concomitant presentation of a PA and a RCC rarely occur. We present a case of a 41-year-old female with Cushing's disease. ⋯ The histological studies revealed an ACTH secreting PA and a RCC. The patient presented clinical and endocrinological remission six months after surgery. With the presence of cystic lesion at the sellar region, and the concomitant finding of a pituitary adenoma, RCC should be considered.

Heart transplantation is currently a procedure of choice for patients with advanced heart failure. Despite a continuous improvement in morbidity and mortality made to date, complications requiring hospitalization continue to be high. The main objective of this study was to describe complications that required hospitalization after a heart transplant, and the secondary objective is to evaluate its incidence according to age group in a cohort of heart transplant recipients in Argentina. ⋯ Mortality density incidence was 8 (95% CI 5.4-11.7) per 100-patients/year for the group that had readmission and 1 per 100-patients/year (95% CI 0.4-2.8) for the group that did not have. We conclude that complications requiring hospitalization are frequent in transplanted patients and affect long-term survival. The main causes of readmission are graft rejection and infections, and they had similar incidence in the age groups we analyzed.

Ticagrelor is anantiplatelet agent which acts through reversible binding to the P2Y12 adenosine-diphosphate receptors. In acute coronary syndromes it has been shown to reduce the risk of major cardiovascular events such as myocardial infarction, stroke and death. Although some hemorrhagic, kidney, liver and respiratory complications have been described in detail with the use of ticagrelor, other less frequent adverse effects are not so well clarified. We report the case of a patient with a systemic inflammatory response syndrome secondary to the use of ticagrelor.

The management of patients with immune-related adverse events (irAEs) frequently demands a multidisciplinary approach. We reviewed the causes and clinical course of medical visits and admissions at the Instituto Alexander Fleming due to irAEs between September 2015 and July 2019. Demographic data, diagnosis, toxicity and its severity, requirement of admission, treatment, mortality, and evaluation of the re-administration of immunotherapy were collected. ⋯ One patient received mycophenolate and one IVIG. In 20, the treatment was discontinued; 8 were re-exposed, with definitive discontinuation in one patient. In this case series we report our experience in the diagnosis and management of adverse reactions related to a family of drugs whose use has grown in recent years.
