RESUMO
Cytokine release syndrome (CRS) is a systemic inflammatory condition caused by an excessive immune response and cytokine overproduction. CRS is a life-threatening condition that is often associated with chimeric antigen receptor T-cell therapy. Despite the increased use of immune checkpoint inhibitors (ICIs), ICI-induced CRS remains rare. The present study describes a case of CRS that occurred after the administration of ICIs for recurrent adenocarcinoma of the uterine cervix. A 49-year-old woman received paclitaxel, carboplatin and pembrolizumab for recurrent cervical adenocarcinoma. On day 27 of the third cycle, the patient was admitted with a fever and suspected pyelonephritis. The following day, hypotension, upper respiratory symptoms and myalgia of the extremities were noted, and the left ventricular ejection fraction (LVEF) was decreased to 20%. Multiorgan failure (MOF) occurred, and the patient received ventilator support and continuous hemodiafiltration. Rhabdomyolysis, pancreatitis, erythema multiforme and enteritis were observed. CRS was diagnosed based on elevated ferritin and IL-6 levels. Steroid pulse therapy was administered; however, the MOF did not improve and the anti-IL-6-receptor monoclonal antibody tocilizumab (TOC) was administered. Subsequently, the LVEF improved to 50%, and the patient was removed from the ventilator on day 4 and from the continuous hemodiafiltration unit on day 6 after TOC administration. The patient was discharged on day 21. In conclusion, considering that ICI-induced CRS is a rare but severe complication, fever and other systemic conditions following ICI administration should be monitored.
RESUMO
We experienced a case of preeclampsia in which massive ascites became apparent in the postpartum period. The patient had isolated proteinuria without hypertension before delivery. The infant had fatal growth restriction and neonatal distress. Massive ascites and isolated proteinuria are important symptoms for predicting the aggravation of PE.
RESUMO
We examined the effects of serotonin (5-HT) depletion induced by peripheral injection of 5-HT synthesis inhibitor p-chlorophenylalanine (PCPA) on the expression of feeding-regulating peptides expressions by using in situ hybridization histochemistry in adult male Wistar rats. PCPA pretreatment had no significant effect on basal levels of oxytocin, corticotropin-releasing hormone (CRH), thyrotropin-releasing hormone (TRH), pro-opiomelanocortin (POMC), cocaine and amphetamine-regulated transcript (CART), neuropeptide-Y (NPY), agouti-related protein (AgRP), melanin-concentrating hormone (MCH) or orexin in the hypothalamus. Food deprivation for 48 h caused a significant decrease in CRH, TRH, POMC, and CART, and a significant increase in NPY, AgRP and MCH. After PCPA treatment, POMC and CART did not decrease despite food deprivation. NPY was significantly increased by food deprivation with PCPA, but was attenuated compared to food deprivation without PCPA. These results suggest that the serotonergic system in the hypothalamus may be involved in the gene expression of POMC, CART, and NPY related to feeding behavior.
