Investigating socioeconomic disparities in lung cancer diagnosis, treatment and mortality: an Italian cohort study.

BACKGROUND: Lung cancer is one of the most lethal cancers worldwide and patient clinical outcomes seem influenced by their socioeconomic position (SEP). Since little has been investigated on this topic in the Italian context, our aim was to investigate the role of SEP in the care pathway of lung cancer patients in terms of diagnosis, treatment and mortality. METHODS: This observational retrospective cohort study included patients discharged in the Lazio Region with a lung cancer diagnosis between 2014 and 2017. In the main analysis, educational level was used as SEP measure. Multivariate models, adjusted for demographic and clinical variables, were applied to evaluate the association between SEP and study outcomes, stratified for metastatic (M) and non-metastatic (NM) cancer. We defined a diagnosis as 'delayed' when patients received their initial cancer diagnosis after an emergency department admission. Access to advanced lung cancer treatments (high-cost, novel and innovative treatments) and mortality were investigated within the 24-month period post-diagnosis. Moreover, two additional indicators of SEP were examined in the sensitivity analysis: one focusing on area deprivation and the other on income-based exemption. RESULTS: A total of 13,251 patients were identified (37.3% with metastasis). The majority were males (> 60%) and over half were older than 70 years. The distribution of SEP levels among patients was as follow: 31% low, 29% medium-low, 32% medium-high and 7% high. As SEP increased, the risks of receiving a delayed diagnosis ((high vs low: M: OR = 0.29 (0.23-0.38), NM: OR = 0.20 (0.16-0.25)) and of mortality ((high vs low M: OR = 0.77 (0.68-0.88) and NM: 0.61 (0.54-0.69)) decreased. Access to advanced lung cancer treatments increased in accordance with SEP only in the M cohort (high vs low: M: OR = 1.57 (1.18-2.09)). The primary findings were corroborated by sensitivity analysis. CONCLUSIONS: Our study highlighted the need of public health preventive and educational programs in Italy, a country where the care pathway of lung cancer patients, especially in terms of diagnosis and mortality, appears to be negatively affected by SEP level.

Immunosuppression with Generics in Liver and Kidney Transplantation: A Real-World Evidence Study.

Purpose: This study evaluates the use, benefit-risk profile, and economic impact of generic immunosuppressants (tacrolimus-TAC, cyclosporine-CsA, and mycophenolate-MYC) in kidney and liver transplant recipients compared to brand-name drugs. Patients and Methods: A retrospective multicentre observational study, involving four Italian regions, was conducted based on the national transplant Information system and regional healthcare claims data. The analysis focused on incident patients who received kidney and liver transplants between 2013 and 2019 and evaluated the use of generic of CsA, TAC, and MYC during the 30-day period following discharge. For each type of transplant and immunosuppressive agent, the benefit-risk profile of generic vs branded drugs in a two-year window was estimated by multivariate Cox models (HR; 95% CI). Furthermore, the potential cost savings per person associated with one year of treatment using generics were calculated. Results: The utilization of generic drugs showed a significant increase; over the study years, the proportion of users among kidney recipients ranged from 14.2% to 40.5% for TAC, from 36.9% to 56.7% for MYC, and from 18.2% to 94.7% for CsA. A great variability in generic uptake for region was found. A comparable risk-benefit profile between generic and branded formulations was shown for all immunosuppressors considered. Choosing generic immunosuppressants during maintenance could result in yearly savings of around 2000 euros per person for each therapy ingredient. Conclusion: The study shows an increasing proportion of patients using generic immunosuppressive drugs over time suggesting a growing acceptance of generics within the transplant community and reveals comparable risk-benefit profiles between the generic and branded formulations of TAC, CsA, and MYC. A significant variability in the use of generics immunosuppressive agents was found both at the regional level and among transplant centers and future research should delve into regional prescribing variations.

Determinants of immunosuppressive therapy in renal transplant recipients: an Italian observational study (the CESIT project).

BACKGROUND: Very scanty evidence is available on factors influencing the choice of immunosuppressive drug therapy after kidney transplantation. METHODS: An Italian multiregional real-world study was conducted integrating national transplant information system and claims data. All patients undergoing kidney transplantation for the first time during 2009-2019 (incident patients) were considered. Multilevel logistic models were used to estimate Odds Ratio (OR) and corresponding 95% Confidence intervals. Factors with statistically significance were identified as characteristics associated with treatment regimens: cyclosporin-CsA vs tacrolimus-Tac and, within the latter group, mTOR inhibitors vs mycophenolate-MMF. RESULTS: We identified 3,622 kidney patients undergoing transplantation in 17 hospitals located in 4 Italian regions, 78.3% was treated with TAC-based therapy, of which 78% and 22% in combination with MMF and mTOR, respectively. For both comparison groups, the choice of immunosuppressive regimens was mostly guided by standard hospital practices. Only few recipient and donor characteristics were found associated with specific regimen (donor/receipt age, immunological risk and diabetes). CONCLUSIONS: The choice of post-renal transplant immunosuppressive therapy seems to be mostly driven by standard Centre practices, while only partially based on patient's characteristics and recognized international guidelines.

An Italian multicentre distributed data research network to study the use, effectiveness, and safety of immunosuppressive drugs in transplant patients: Framework and perspectives of the CESIT project.

The goal of post-transplant immunosuppressive drug therapy is to prevent organ rejection while minimizing drug toxicities. In clinical practice, a multidrug approach is commonly used and involves drugs with different mechanisms of action, including calcineurin inhibitors (CNI) (tacrolimus or cyclosporine), antimetabolite (antimet) (mycophenolate or azathioprine), inhibitors of mechanistic target of rapamycin (mTOR) (sirolimus or everolimus), and/or steroids. Although evidence based on several randomized clinical trials is available, the optimal immunosuppressive therapy has not been established and may vary among organ transplant settings. To improve the knowledge on this topic, a multiregional research network to Compare the Effectiveness and Safety of Immunosuppressive drugs in Transplant patients (CESIT) has been created with the financial support of the Italian Medicines Agency. In this article, we describe the development of this network, the framework that was designed to perform observational studies, and we also give an overview of the preliminary results that we have obtained. A multi-database transplant cohort was enrolled using a common data model based on healthcare claims data of four Italian regions (Lombardy, Veneto, Lazio, and Sardinia). Analytical datasets were created using an open-source tool for distributed analysis. To link the National Transplant Information System to the regional transplant cohorts, a semi-deterministic record linkage procedure was performed. Overall, 6,914 transplant patients from 2009-19 were identified: 4,029 (58.3%) for kidney, 2,219 (32.1%) for liver, 434 (6.3%) for heart, and 215 (3.1%) for lung. As expected, demographic and clinical characteristics showed considerable variability among organ settings. Although the triple therapy in terms of CNI + antimet/mTOR + steroids was widely dispensed for all settings (63.7% for kidney, 33.5% for liver, 53.3% for heart, and 63.7% for lung), differences in the active agents involved were detected. The CESIT network represents a great opportunity to study several aspects related to the use, safety, and effectiveness of post-transplant maintenance immunosuppressive therapy in real practice.

Direct and Indirect Impact of COVID-19 for Patients with Immune-Mediated Inflammatory Diseases: A Retrospective Cohort Study.

IMPORTANCE: Since the beginning of the Coronavirus Disease-19 (COVID-19) pandemic, Severe Acute Respiratory Syndrome-CoV-2 (SARS-CoV-2) infection has been a serious challenge for immune-compromised patients with immune-mediated inflammatory diseases (IMIDs). OBJECTIVE: Our aim was to investigate the impact of COVID-19 in terms of risks of infection, hospitalization and mortality in a cohort of patients with rheumatoid arthritis (RA), psoriasis (PSO) or inflammatory bowel disease (IBD). Furthermore, we studied the impact of SARS-CoV-2 infection on the prescribed drug regimen in these patients. METHODS: Through the record linkage between health information systems, a cohort of patients, ≥18 years old, assisted in the Lazio region and who had suffered from immune-mediated inflammatory diseases (RA, PSO, IBD) between 2007 and 2019, was identified. The risk of infection, hospitalization or mortality for COVID-19, was assessed by logistic regression models, and reported in an Odds Ratio (ORs; CI 95%), adjusting for sex, age and the Charlson Comorbidity Index. We also estimated these risks separately by IMID and in the subgroup of prevalent biologic drug users. We investigated deferral of biological treatments in the study population by comparing the prevalence of weekly use of biologicals (2019-2020) before and during the pandemic periods. FINDINGS: Within the 65,230 patients with IMIDs, the cumulative incidence for COVID-19 was 303/10,000 ab. In this cohort of patients, we observed a significantly higher risk of SARS-CoV-2 infection than the general population: OR = 1.17 (95% CI 1.12-1.22). The risk was higher even considering separately each disease and in the subgroup of prevalent biologic drug users. This last subgroup of patients showed a higher risk of death related to COVID-19 (OR 1.89; 95% CI 1.04-3.33) than the general population. However, no differences in terms of risks of hospitalization or death related to COVID-19 were recorded in patients with the IMIDs. Comparing the 2019-2020 prevalence of weekly biological drug treatments in prevalent biologic drug users, we found a decrease (-19.6%) during the lockdown, probably due to pandemic restrictions. CONCLUSIONS AND RELEVANCE: Patients with IMIDs seem to have a higher risk of SARS-CoV2 infection. However, other than for patients with prevalent biologic drug treatment, no significant differences in terms of hospitalization and mortality were reported compared to the general populations; further investigation is warranted on account of unmeasured confounding. In addition, during the lockdown period, the COVID-19 emergency highlighted a lower use of biologic drugs; this phenomenon requires strict pharmacological monitoring as it could be a proxy of forthcoming long-term clinical progression.

Drug discontinuation in pregnant women with psoriasis: The PSO-MOTHER cohort study.

PURPOSE: To analyse the drug use pattern in women with psoriasis before, during and after pregnancy. METHODS: All children born (2009-2016) in a central Italian region (Lazio) to mothers with a diagnosis of psoriasis were identified. Drug use patterns (biologicals, systemic, and topical), and discontinuation and switching of drug therapies before, during, and after pregnancy were studied. Findings were compared with data from a population exposed to similar drug therapies (eg, antirheumatic drugs). RESULTS: Among 3499 deliveries by women affected by psoriasis, 1876 (53.6%) were diagnosed with this condition before the Last Menstrual Period (LMP). Of these, 525 (27.9%) had at least one drug prescription for psoriasis therapy during 6 months before LMP. For each class of drugs considered, there was a general decrease in its use during pregnancy. Considering the two trimesters preceding LMP and the three trimesters of pregnancy, the following percentages of prescriptions were observed: from 10.5% to 0% for biologicals, 7.2% to 2.5% for the conventional systemic drugs, and 51.1% to 9.4% for the topical treatments. After delivery, previous treatments were resumed. Similar results were observed for rheumatoid arthritis, a chronic condition. CONCLUSIONS: Majority of drugs come with warnings regarding potential embryo-fetotoxicity, which might play a role in the decision to continue treatments during pregnancy. According to our study pregnancy appears to have a significant influence on drug prescriptions of different pharmacological treatments for psoriasis.
