Background Cutaneous immune-related adverse events (irAEs) represent the most frequent toxicities induced by immune checkpoint inhibitors (ICIs). Objectives To investigate clinical associations of cutaneous toxicities induced by different ICI therapies. Methods This was a multicentre retrospective international cohort study of patients with cancer who developed cutaneous irAEs under ICI therapy. Analysis was performed of the rates and basic characteristics of all cutaneous toxicities, and identification of any associations was performed using univariate and multivariate models. Results In total, 762 patients were included, who developed 993 cutaneous toxicities. Forty different types of skin toxicities were identified. Psoriasis (175 patients, 23Á0%) and pruritus (171 patients, 22Á4%) were the most common toxicities, followed by macular rash (161 patients, 21Á1%) and eczematous-type reactions (150 patients, 19Á7%). Multivariate analysis showed that among
Expression of Transcribed Ultraconserved Regions (T-UCRs) is often deregulated in cancer. The present study assesses the expression and methylation of three T-UCRs (Uc160, Uc283 and Uc346) in colorectal cancer (CRC) and explores the potential of T-UCR methylation in circulating DNA for the detection of adenomas and adenocarcinomas.Expression levels of Uc160, Uc283 and Uc346 were lower in neoplastic tissues from 64 CRC patients (statistically significant for Uc160, p<0.001), compared to non-malignant tissues, while methylation levels displayed the inverse pattern (p<0.001, p=0.001 and p=0.004 respectively). In colon cancer cell lines, overexpression of Uc160 and Uc346 led to increased proliferation and migration rates. Methylation levels of Uc160 in plasma of 50 CRC, 59 adenoma patients, 40 healthy subjects and 12 patients with colon inflammation or diverticulosis predicted the presence of CRC with 35% sensitivity and 89% specificity (p=0.016), while methylation levels of the combination of all three T-UCRs resulted in 45% sensitivity and 74.3% specificity (p=0.013). In conclusion, studied T-UCRs’ expression and methylation status are deregulated in CRC while Uc160 and Uc346 appear to have a complicated role in CRC progression. Moreover their methylation status appears a promising non-invasive screening test for CRC, provided that the sensitivity of the assay is improved.
Background
Real‐world data in patients with moderate psoriasis treated with apremilast is limited.
Objectives
To evaluate the effectiveness and safety of apremilast in bio‐naïve patients with moderate psoriasis in real‐world clinical settings.
Methods
This was a 52‐week multicenter, observational, prospective study of adult outpatients with moderate psoriasis {[10% < body surface area < 20% or 10 < psoriasis area severity index (PASI) < 20] and 10 < dermatology quality of life index (DLQI) < 20} initiated on apremilast ≤7 days before enrollment. Missing data were imputed using the last observation carried forward method.
Results
A total of 287 eligible patients (median age: 54.2 years; median psoriasis duration: 9.8 years) were consecutively enrolled. At baseline, the median DLQI and PASI scores were 12.0 and 11.8, respectively. The 52‐week DLQI ≤ 5 and PASI75 response rates were 68.3% and 61.0%. At 52 weeks, 70.8% and 72.7% of the patients shifted from moderate/severe/very severe to clear/minimal scalp and palmoplantar psoriasis involvement, respectively; the pruritus severity state improved in 67.2%. The 52‐week Kaplan–Meier estimated drug continuation rate was 85.3%. The adverse drug reaction rate was 19.9%.
Conclusions
Apremilast is a safe and effective treatment for bio‐naïve patients with moderate psoriasis and specific psoriasis manifestations.
