Clinical outcomes of patients with corticosteroid refractory immune checkpoint inhibitor-induced enterocolitis treated with infliximab.

INTRODUCTION: Immune checkpoint inhibitors (CPIs) have changed the treatment landscape for many cancers, but also cause severe inflammatory side effects including enterocolitis. CPI-induced enterocolitis is treated empirically with corticosteroids, and infliximab (IFX) is used in corticosteroid-refractory cases. However, robust outcome data for these patients are scarce. METHODS: We conducted a multicenter (six cancer centers), cohort study of outcomes in patients treated with IFX for corticosteroid-refractory CPI-induced enterocolitis between 2007 and 2020. The primary outcome was corticosteroid-free clinical remission (CFCR) with Common Terminology Criteria for Adverse Events (CTCAE) grade 0 for diarrhea at 12 weeks after IFX initiation. We also assessed cancer outcomes at 1 year using RECIST V1.1 criteria. RESULTS: 127 patients (73 male; median age 59 years) were treated with IFX for corticosteroid-refractory CPI-induced enterocolitis. Ninety-six (75.6%) patients had diarrhea CTCAE grade >2 and 115 (90.6%) required hospitalization for colitis. CFCR was 41.2% at 12 weeks and 50.9% at 26 weeks. In multivariable logistic regression, IFX-resistant enterocolitis was associated with rectal bleeding (OR 0.19; 95% CI 0.04 to 0.80; p=0.03) and absence of colonic crypt abscesses (OR 2.16; 95% CI 1.13 to 8.05; p=0.03). Cancer non-progression was significantly more common in patients with IFX-resistant enterocolitis (64.4%) as compared with patients with IFX-responsive enterocolitis (37.5%; p=0.013). CONCLUSION: This is the largest study to date reporting outcomes of IFX therapy in patients with corticosteroid-refractory CPI-induced enterocolitis. Using predefined robust endpoints, we have demonstrated that fewer than half of patients achieved CFCR. Our data also indicate that cancer outcomes may be better in patients developing prolonged and severe inflammatory side effects of CPI therapy.

Nurse Jackie and the politics of care.

This essay considers Nurse Jackie, one of several recent television shows, including HawthoRNe, and Mercy, that features a nurse as the main character. All 3 shows premiered in 2009 and challenged nursing's longstanding invisibility and misrepresentation on television. Although the plots of each show corrected problematic aspects of nursing's usual media representation, only Nurse Jackie remains on the air. In this paper, I analyze why Nurse Jackie succeeded where the other 2 shows did not, considering the representational politics of care on television and in the national context where health care remains a significant concern.

Self-reported quality of life in children and young people with chronic kidney disease.

Chronic kidney disease (CKD) would be expected to impact upon the quality of life (QoL) of children and young people; therefore, it is important that they are given the means to express their opinions about how they perceive their own QoL. We used the Generic Children's Quality of Life Measure (GCQ) in 225 paediatric renal patients (118 male, mean age 13.6 years, range 6.2-18.9 years) from seven UK centres. Of these, 47 were on dialysis (23 on haemodialysis), 128 were post-transplant (47 pre-emptive) and 49 had advanced CKD. A comparison between the 124 renal patients (65 male, mean age 11.2 years) in the same age range as the general population (6-14 years) showed a higher GCQ QoL score for the renal patients (p = 0.02). Analysis of the whole group of renal patients (n = 225) revealed no significant difference between the mean GCQ scores of participants in various treatment modalities (p = 0.26) and no significant differences between gender (p = 0.90) and age group (p = 0.44). The results indicate that young people can perceive their QoL as good despite living with what others may perceive as severe limitations. This may seem counter-intuitive, but QoL is a subjective measure and thus may be difficult to predict from observable limitations (health status). The GCQ is an ideal measure for use in annual departmental audits of generic paediatric QoL and may help to individualise the work of psychosocial teams with each patient.

Pneumonia in term neonates: laboratory studies and duration of antibiotic therapy.

OBJECTIVES: To compare 2 days of antibiotic therapy (AT) to 4 days of AT in neonates with pneumonia and to assess the usefulness of neutrophil values (NV), C-reactive protein (CRP), and procalcitonin (PCT) in this population. DESIGN: The study population consisted of consecutive, eligible term neonates begun on AT for suspected pneumonia. Of 51 neonates, 26 qualified for randomization (14, 2-day group; 12, 4-day group). NV were obtained with the initial evaluation and 12 and 24 hours later. CRP and PCT were obtained 12 and 48 hours after the initial evaluation. RESULTS: None of the 12 neonates in the 4-day group developed recurrent respiratory symptoms. Three of the 14 neonates randomized to the 2-day group had recurrence of symptoms, resulting in study termination. NV, CRP, and PCT were similar in the 2- and 4-day groups. In the three neonates who developed respiratory symptoms, all absolute total neutrophil values and five out of nine absolute total immature neutrophil values were abnormal. However, all immature:total neutrophil values were normal, and CRP was strikingly elevated in only one neonate; only one of six PCT values was abnormal. In a secondary analysis of all 51 study neonates, CRP and PCT did not provide additional benefit over NV in differentiating neonates with pneumonia. CONCLUSIONS: Four days of AT appears to be adequate for selected term neonates with pneumonia; however, 2 days of AT appears to be inadequate for this population. Relative to NV, CRP and PCT appear to have a limited role.
