Background

Previous studies have reported that rituximab (RTX) therapy might be beneficial in reducing relapse rates in patients with IgG4-related disease (IgG4-RD). Therefore, we aimed to systematically assess the efficacy and safety of RTX induction treatment and the effect of RTX maintenance in patients with IgG4-RD.

Methods

The protocol was registered in the PROSPERO (CRD42023427352). PubMed, Embase, the Cochrane database, Scopus, and the Web of Science were interrogated to identify studies that evaluated the impact of RTX on prognosis in IgG4-RD. We explored the impact of various subgroups of factors on relapse outcomes and focused on the possible role of maintenance therapy in reducing relapse rates. The pooled incidence of adverse events of RTX therapy and the influencing factors have also been evaluated.

Results

Eighteen studies comprising 374 patients (mean age 56.0 ± 8.7 years; male 73.7 %) with a mean follow-up duration of 23.4 ± 16.3 months were included. The pooled estimate of the response rate, complete remission rate, overall relapse rate, adverse event rate, and serious adverse event rate of RTX induction therapy were 97.3 % (95 % CI, 94.7 %–99.1 %), 55.8 % (95 % CI, 39.6 %–71.3 %), 16.9 % (95 % CI, 8.7 %–27.1 %), 31.6 % (95 % CI, 16.7 %–48.9 %) and 3.9 % (95 % CI, 0.8 %–8.9 %), respectively. In subgroup analysis, the pooled relapse rate was significantly lower in studies with maintenance than without maintenance (2.8% vs 21.5 %, p < 0.01). Pooled Kaplan-Meier relapse curves also demonstrated that RTX maintenance therapy provided a better prognosis.

Conclusions

RTX induction therapy appears to have satisfactory efficacy in the induction of remission in IgG4-RD. In addition, prophylactic RTX maintenance therapy after induction may be beneficial in preventing relapse of IgG4-RD.

Background

With their broad presentations and no global biomarker to discriminate crises and attack-free periods, Systemic Auto-Inflammatory Diseases (SAID) are difficult to manage. This study assessed Serum Amyloid A (SAA), C-reactive protein (CRP) and serum calprotectin as potential biomarkers to monitor patients with SAID.

Method

SAA (already studied in Familial Mediterranean Fever (FMF)), CRP and serum calprotectin were measured on SAID adult patients from Juvenile Inflammatory Rheumatism (JIR) cohort during their follow-up visits between 2020 and 2022. Crises and attack-free periods were clinically determined.

Results

96 measures, mainly from FMF (43 %) and Unclassified SAID (USAID) (37 %) patients were included. Using ROC curves, a threshold with sensitivity and specificity of/over 75 % was determined for SAA (9 mg/L) and CRP (9 mg/L) but not for serum calprotectin, not investigated further. With this threshold, the results were similar in FMF and USAID patients’ subgroups. SAA and CRP showed a positive correlation with crises and attack-free periods in SAID patients (r = 0.4796, p < 0.001 and r = 0.5525, p < 0.001, respectively) as in FMF and USAID patients, with no significant difference between both markers in diagnosis value and ROC curves Area Under Curve (AUC) (p = 0.32). Only the CRP results were not influenced by obesity.

Conclusion

SAA and CRP can discriminate crisis and attack-free periods in our cohort of SAID patients mainly composed of FMF and USAID patients. However, only CRP can be used regardless of body mass index. It is the first report of common biomarkers for all SAID, including USAID patients, with CRP widely accessible in routine worldwide.

Introduction

Exacerbations of chronic obstructive pulmonary disease (COPD) can increase the risk of severe cardiovascular events.

Objective

Assess the crude incidence rates (IR) of cardiovascular events and the impact of exacerbations on the risk of cardiovascular events within different time periods following an exacerbation.

Methods

COPD patients aged ≥45 years between 01/01/2015 and 12/31/2018 were identified from the Fondazione Ricerca e Salute administrative database. IRs of severe non-fatal and fatal cardiovascular events were obtained for post-exacerbation time periods (1–7, 8–14, 15–30, 31–180, 181–365 days). Time-dependent Cox proportional hazard models compared cardiovascular risks between periods with and without exacerbations.

Results

Of 216,864 COPD patients, >55 % were male, mean age was 74 years, frequent comorbidities were cardiovascular, metabolic and psychiatric. During an average 34-month follow-up, 69,620 (32 %) patients had ≥1 exacerbation and 46,214 (21 %) experienced ≥1 cardiovascular event. During follow-up, 55,470 patients died; 4,661 were in-hospital cardiovascular-related deaths. Among 10,269 patients experiencing cardiovascular events within 365 days post-exacerbation, the IR was 15.8 per 100 person-years (95 %CI 15.5–16.1). Estimated hazard ratios (HR) for the cardiovascular event risk associated with periods post-exacerbation were highest within 7 days (HR: 34.3, 95 %CI: 33.1–35.6), especially for heart failure (HR 50.6; 95 %CI 48.6–52.7) and remained elevated throughout 365 days (HR 1.1, 95 %CI 1.02–1.13).

Conclusions

COPD patients in Italy are at high risk of severe cardiovascular events following exacerbations, suggesting the need to prevent exacerbations and possible subsequent cardiovascular events through early interventions and treatment optimization.

Objective

To investigate the association of the addition of thiazide diuretic on top of loop diuretic and standard of care with short-term outcomes of patients discharged after surviving an acute heart failure (AHF) episode.

Methods

This is a secondary analysis of 14,403 patients from three independent cohorts representing the main departments involved in AHF treatment for whom treatment at discharge was recorded and included loop diuretics. Patients were divided according to whether treatment included or not thiazide diuretics. Short-term outcomes consisted of 30-day all-cause mortality, hospitalization (with a separate analysis for hospitalization due to AHF or to other causes) and the combination of death and hospitalization. The association between thiazide diuretics on short-term outcomes was explored by Cox regression and expressed as hazard ratios (HR) with 95 % confidence intervals, which were adjusted for 18 patient-related variables and 9 additional drugs (aside from loop and thiazide diuretics) prescribed at discharge.

Results

The median age was 81 (interquartile range=73–86) years, 53 % were women, and patients were mainly discharged from the cardiology (42 %), internal medicine or geriatric department (29 %) and emergency department (19 %). There were 1,367 patients (9.5 %) discharged with thiazide and loop diuretics, while the rest (13,036; 90.5 %) were discharged with only loop diuretics on top of the remaining standard of care treatments. The combination of thiazide and loop diuretics showed a neutral effect on all outcomes: death (adjusted HR 1.149, 0.850–1.552), hospitalization (0.898, 0.770–1.048; hospitalization due to AHF 0.799, 0.599–1.065; hospitalization due to other causes 1.136, 0.756–1.708) and combined event (0.934, 0.811–1.076).

Conclusion

The combination of thiazide and loop diuretics was not associated with changes in risk of death, hospitalization or a combination of both.

Background

Direct oral anticoagulants (DOACs) have become widely used for cancer-associated venous thromboembolism (VTE). However, DOAC-associated bleeding complications remain challenging, especially in patients with gastrointestinal (GI) cancer. This study aimed to compare the bleeding outcomes between patients with upper or lower GI cancers and those without GI cancer.

Methods

Using the COMMAND VTE Registry-2 database, which is a multicenter registry enrolling 5197 consecutive acute symptomatic VTE patients among 31 centers in Japan between January 2015 and August 2020, we identified 1149 active cancer patients with DOACs (upper GI cancer: N = 88; lower GI cancer: N = 114; non-GI cancer: N = 947). The primary outcome was major bleeding during anticoagulation therapy, which was evaluated in the competing risk regression model.

Results

The upper GI cancer group had a lower mean body weight, and most often had anemia. The cumulative 5-year incidence of major bleeding was higher in the upper GI cancer group (upper GI cancer: 22.4 %, lower GI cancer: 15.4 %, and non-GI cancer: 11.6 %, P = 0.015). The most frequent major bleeding site in the upper GI cancer group was the upper GI (53 %), followed by the lower GI (24 %). After adjusting for the confounders, the excess risk in upper GI cancer relative to non-GI cancer remained significant for major bleeding (adjusted subhazard ratio, 2.25; 95 %CI, 1.31–3.87, P = 0.003), but that in lower GI cancer was insignificant.

Conclusions

Upper GI cancer, but not lower GI cancer, as compared to non-GI cancer was associated with a higher risk for major bleeding during anticoagulation therapy with DOACs.

Background

the burden of acute complex patients, increasingly older and poli-pathological, accessing to Emergency Departments (ED) leads up hospital overcrowding and the outlying phenomenon. These issues highlight the need for new adequate patients’ management strategies.

The aim of this study is to analyse the effects on in-hospital patient flow and clinical outcomes of a high-technology and time-limited Medical Admission Unit (MAU) run by internists.

Methods

all consecutive patients admitted to MAU from Dec-2017 to Nov-2019 were included in the study. The admissions number from ED and hospitalization rate, the overall in-hospital mortality rate in medical department, the total days of hospitalization and the overall outliers bed days were compared to those from the previous two years.

Results

2162 patients were admitted in MAU, 2085(95.6%) from ED, 476(22.0%) were directly discharged, 88(4.1%) died and 1598(73.9%) were transferred to other wards, with a median in-MAU time of stay of 64.5 [0.2–344.2] hours. Comparing the 24 months before, despite the increase in admissions/year from ED in medical department (3842 ± 106 in Dec2015–Nov2017 vs 4062 ± 100 in Dec2017-Nov2019, p<0.001), the number of the outlier bed days has been reduced, especially in surgical department (11.46 ± 6.25% in Dec2015–Nov2017 vs 6.39 ± 3.08% in Dec2017-Nov2019, p=0.001), and mortality in medical area has dropped from 8.74 ± 0.37% to 7.29 ± 0.57%, p<0.001.

Conclusions

over two years, a patient-centred and problem-oriented approach in a medical admission buffer unit run by internists has ensured a constant flow of acute patients with positive effects on clinical risk and quality of care reducing medical outliers and in-hospital mortality.
