IDDSs improved clinical success in pain control, reduced pain, significantly relieved common drug toxicities, and improved survival in patients with refractory cancer pain.
Pain has become the most common accompanying symptom in patients seeking medical advice, and it is one of the main issues in public health. In Spain, there are no reliable data about the impact of pain in general population. The aim of the study was to estimate the prevalence of acute and chronic pain in the Spanish general population. An epidemiological observational population-based cross-sectional study was carried out by means of a telephone survey. Multistep stratified quota-adjusted sampling was performed with people aged 18-95 years. A computer-assisted questionnaire was administered, covering physical pain symptoms, site, frequency, perceived cause, therapeutic measures and interference with daily life activities. There were 11,980 useful contacts, with 5000 effective interviews (42% of useful sample). Of the interviewees, 29.6% (95% confidence interval, 28.3-30.8%) reported having had pain the day before (women, 37.6%; men, 20.9%) and 43.2% the week before. Most common pain sites were lower extremities (22.7%) and back (cervical and lumbar levels) (21.5%), followed by head (20.5%). Frequency of pain increased with age, reaching 42.6% for people older than 65 years. Among people complaining of pain during the last day or week, duration of symptoms was higher than 3 months in 54% (chronic pain), representing 23.4% of the Spanish general population; most common causes of chronic pain were arthritis, rheumatism and migraine. Regarding treatment, 61.7% of people complaining of pain said they were taking drugs. Source of drug treatment advice was a physician or a nurse in 66.4% of cases and self-prescription in 29%. It is concluded that pain, particularly chronic pain, has a high prevalence in the Spanish general population and a significant impact on occupational and social relationships.
IDDS improved clinical success, reduced pain scores, relieved most toxicity of pain control drugs, and was associated with increased survival for the duration of this 6 month trial.
Recent studies have demonstrated a suboptimal humoral response to SARS-CoV-2 mRNA vaccines in patients diagnosed with hematologic malignancies, however data about cellular immunogenicity is scarce. In this study we aimed to evaluate both the humoral and cellular immunogenicity one month after the second dose of the mRNA-1273 vaccine. Antibody titers were measured by the Elecsys and LIAISON Anti-SARS-CoV-2 S assay while T-cell response was assessed by Interferon-Gamma-Release-immuno-Assay technology. Overall, 76.3% (184/241) of patients developed humoral immunity and the cellular response rate was 79% (184/233). Hypogammaglobulinemia, lymphopenia, active hematological treatment and anti-CD20 therapy during the last 6 months were associated with an inferior humoral response. Conversely, age over 65 years, active disease, lymphopenia and immunosuppressive treatment for GvHD were associated with an impaired cellular response. A significant dissociation between humoral and cellular response was observed in patients treated with anti-CD20 therapy, being the humoral response of 17.5% whereas the cellular response was 71.1%. In these patients B-cell aplasia was confirmed while T cell counts were preserved. In contrast, humoral response was observed in 77.3% of patients under immunosuppressive treatment for GvHD, while only 52.4% had cellular response. The cellular and humoral response to the SARS-CoV-2 mRNA-1273 vaccine in patients with hematological malignancies is highly influenced by the presence of treatments like anti-CD20 therapy and immunosuppressive agents. This observation has implications for the further management of these patients.
Axicabtagene ciloleucel (axi-cel) and tisagenlecleucel (tisa-cel) are CD19-targeted chimeric antigen receptor (CAR) T-cells approved for relapsed/refractory (R/R) large B-cell lymphoma (LBCL). We performed a retrospective study to evaluate safety and efficacy of axi-cel and tisa-cel outside the setting of a clinical trial. Data from consecutive patients with R/R LBCL who underwent apheresis for axi-cel or tisa-cel were retrospectively collected from 12 Spanish centers. A total of 307 patients underwent apheresis for axi-cel (n=152) and tisa-cel (n=155) from Nov-2018 to Aug-2021, of which 261 (85%) received a CAR-T infusion (88% and 82%, respectively). Median time from apheresis to infusion was 41 days for axi-cel and 52 days for tisa-cel (p=0.006). None of the baseline characteristics were significantly different between both cohorts. Both cytokine release syndrome and neurologic events (NE) were more frequent in the axi-cel group (88% vs 73%, p=0.003, and 42% vs 16%, p
Neurolytic celiac plexus block (NCPB) is claimed to be an effective method of pain control for pancreatic cancer pain. However, the factors that may influence long-term analgesia, adverse effects, and quality of life after performing NCPB have never been determined. In a prospective multicenter study, 22 patients who underwent NCPB were followed until death. Numerous parameters other than pain and symptom intensity were evaluated, including age, gender, initial site of cancer, sites of pain, possible peritoneal involvement, technique, and oncologic interventions. Indices were calculated to determine the opioid consumption ratio (EAS) and the trend of opioid escalation (OEI). NCPB was effective in reducing opioid consumption and gastrointestinal adverse effects for at least 4 weeks. In the last four weeks prior to death, there was the typical trend of increasing symptom intensity common to the terminal cancer population. None of the factors studied influenced the analgesic effectiveness of NPCB. NPCB, performed by skilled clinicians, regardless of the technique chosen, is a safe and useful means that should be considered as an adjuvant to common analgesic regimens at any stage, as it may allow the reduction of the visceral component of pancreatic pain that may prevail in certain phases of the illness. The analgesic and symptomatic effect of NCPB is presumably advantageous for about four weeks. A possible factor interfering with long-term outcome includes the capacity of cancer to involve the celiac axis, which can distort the anatomy and prevent neurolytic spread, or modify the pain mechanisms. Outcomes are strongly based on individual variation.
