AI Article Synopsis
- Three categories of biologics—TNF inhibitors, IL-17 inhibitors, and IL-23 inhibitors—are used to treat severe psoriasis, with recent research highlighting the relevance of specific lab biomarkers (like NLR, PLR, MLR, and CRP) in determining disease severity.
- A study involving 67 patients assessed the relationship between these biomarkers and disease activity, using a statistical model to link lab results with the psoriasis area and severity index (PASI) scores.
- Results showed that both CRP and NLR were significantly correlated with PASI scores in all patients, with NLR emerging as the most consistent biomarker, particularly effective in patients treated with IL-17 inhibitors.
Article Abstract
Background: Three categories of biologics-tumor necrosis factor (TNF) inhibitors, interleukin (IL) -17 inhibitors, and IL-23 inhibitors-are available for treatment of refractory psoriasis. Recent studies have shown that laboratory biomarkers such as peripheral blood neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), monocyte-lymphocyte ratio (MLR), and serum C-reactive protein (CRP) levels are associated with psoriasis or its severity. This study evaluated associations of transition of NLR, PLR, MLR, and CRP with transition of disease activity in psoriasis patients treated with the three categories of biologics.
Methods: Data from 67 patients were analyzed. Associations of transition of psoriasis area and severity index (PASI) score with the abovementioned laboratory markers were evaluated by using a mixed effects model with PASI as the response variable, laboratory markers as fixed effects collectively, and patients as random effects.
Results: In an analysis of all the patients, serum CRP and NLR were associated with PASI score (P=0.006 and P=0.001, respectively). In patients treated with TNF inhibitors, CRP and NLR were associated with PASI score (P=0.043 and P=0.002, respectively). In patients treated with IL-17 inhibitors, NLR was associated with PASI score (P=0.001).
Conclusions: NLR appears to be the most reliable biomarker of the effect of treatment with biologics, especially IL-17 inhibitors.

Ente Ospedaliero Cantonale, Switzerland.
The Swiss Group for Clinical Cancer Research (SAKK) and the Nordic Lymphoma Group (NLG) conducted the SAKK 35/10 randomized phase-2 trial (NCT0137605) to compare rituximab (R) alone versus R plus lenalidomide (L) as initial treatment for follicular lymphoma (FL). Patients with grade 1-3a FL, requiring systemic therapy, were randomized to either R (n=77; 375 mg/m2 IV x 1, weeks 1-4) or RL (n=77; R on the same schedule and L at 15 mg daily continuously). Responders (evaluated at 10 weeks) repeated R during weeks 12-15 with or without L (for a total of 18 weeks).

In this study, we first analyzed data from 147 patients with solitary plasmacytomas treated at the Mayo Clinic between 2005 and 2022 and then expanded our investigation through a systematic review and meta-analysis of 62 studies, encompassing 3,487 patients from the years 1960 to 2022. Our findings reveal that patients with up to 10% clonal plasma cells in their bone marrow (BM), denoted as plasmacytoma +, had a significantly reduced median disease-free survival (DFS) of 15.7 months vs.

Emerging evidence indicates that delayed CAR T-cell infusion, including prolonged time from leukapheresis to infusion, known as vein-to-vein time (V2Vt), may adversely impact clinical outcomes. We conducted a systematic literature review (SLR) and meta-analysis to identify differences in V2Vt in patients with R/R LBCL treated with axi-cel, tisa-cel, or liso-cel.

The phase 2 CLL2-BZAG trial tested a measurable residual disease (MRD)-guided combination treatment of zanubrutinib, venetoclax and obinutuzumab after an optional bendamustine debulking in patients with relapsed/refractory CLL. In total, 42 patients were enrolled and two patients with ≤2 induction cycles were excluded from the analysis population per protocol. Patients had a median of one prior therapy (range 1-5), 18 patients (45%) had already received a BTK inhibitor (BTKi), seven patients (17.

Background: Opioid medications are important for pain management, but many patients progress to unsafe medication use. With few personalized and accessible behavioral treatment options to reduce potential opioid-related harm, new and innovative patient-centered approaches are urgently needed to fill this gap.
Objective: This study involved the first phase of co-designing a digital brief intervention to reduce the risk of opioid-related harm by investigating the lived experience of chronic noncancer pain (CNCP) in treatment-seeking patients, with a particular focus on opioid therapy experiences.
