Inflammatory bowel disease (IBD), once thought to impact younger individuals, now manifests in approximately 10% of patients over 65, characterized by a heightened vulnerability to complications and greater diagnostic intricacies than conventional cases. However, comprehensive global epidemiological data regarding elderly-onset IBD are currently insufficient. Our study addresses this critical gap by analyzing trends in elderly-onset IBD over a decade, encompassing the estimation of annual frequencies and age-standardized rates of elderly-onset IBD burden for both genders, stratifying the data by geographical and sociodemographic factors. Our research highlights a notable increase in the proportion of elderly-onset IBD, constituting around 13% of all IBD cases. We observed a rising incidence in males, contrasted by a decreasing trend in females. The highest surge in incidence rates was seen in the Western Pacific region in both genders, but the highest burden was observed in America. Countries with high sociodemographic index (SDI) carried the greatest burden of elderly-onset IBD, while countries with low SDI had the least. The mortality and disability-adjusted life years (DALYs) rates trend downward in most regions. This study underscores an increasing incidence and proportion of IBD, particularly in elderly-onset IBD, particularly in males. While mortality and DALYs are decreasing in most regions, the overall burden remains highest in America and high-SDI countries. Effective public health interventions and comprehensive studies are required to tackle this mounting burden.

Background: Vascular pythiosis, caused by Pythium insidiosum, is a life-threatening disease with high mortality rate in patients with residual disease post-surgery. This study evaluated the effectiveness of a combination therapy of surgery, azithromycin, doxycycline, and itraconazole. Methods: In this open-label, Phase II multicenter trial, 51 patients were enrolled. Patients were categorized based on residual disease post-surgery (unresectable lesions, incomplete resection, or persistent symptoms). Patients with residual disease received azithromycin (500 mg daily), doxycycline (100 mg twice daily), and itraconazole (200 mg thrice daily) until beta-d-glucan (BDG) levels were negative (<80 pg/mL) for 3 months. Those without residual disease received the same regimen for 6 months. Outcomes included all-cause mortality at 6 months, adverse events, changes in BDG levels over time, and factors associated with residual disease and mortality. Results: At 6 months, the all-cause mortality rate was 15.7%. Mortality in patients with residual disease was 31.5% compared to 6.25% for those without (P = .04). Lesions above the popliteal artery were a significant predictor of residual disease (incidence rate ratio [IRR] 3.20, 95% confidence interval [CI]: 1.08–11.70). BDG levels decreased over time (odds ratio [OR] 0.82, 95% CI: .77–.88 per week, P < .001) but remained higher in the residual disease group (OR 4.29, 95% CI: 1.55–11.92) Conclusions: The combination therapy of surgery, azithromycin, doxycycline, and itraconazole improves survival in patients with vascular pythiosis, including those with residual disease. This regimen is well tolerated and should be considered a standard of care, with further research needed for long-term outcomes.

Immunogenicity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination is diminished in hematopoietic stem cell transplant (HSCT) recipients. To summarize current evidence and identify risk factors for attenuated responses, 5 electronic databases were searched since database inceptions through 12 January 2023 for studies reporting humoral and/or cellular immunogenicity of SARS-CoV-2 vaccination in the HSCT population. Using descriptive statistics and random-effects models, extracted numbers of responders and pooled odds ratios (pORs) with 95% confidence intervals (CIs) for risk factors of negative immune responses were analyzed (PROSPERO: CRD42021277109). From 61 studies with 5906 HSCT recipients, after 1, 2, and 3 doses of messenger RNA (mRNA) SARS-CoV-2 vaccines, the mean antispike antibody seropositivity rates (95% CI) were 38% (19-62), 81% (77-84), and 80% (75-84); neutralizing antibody seropositivity rates were 52% (40-64), 71% (54-83), and 78% (61-89); and cellular immune response rates were 52% (39-64), 66% (51-79), and 72% (52-86). After 2 vaccine doses, risk factors (pOR; 95% CI) associated with antispike seronegativity were male recipients (0.63; 0.49-0.83), recent rituximab exposure (0.09; 0.03-0.21), haploidentical allografts (0.46; 0.22-0.95), <24 months from HSCT (0.25; 0.07-0.89), lymphopenia (0.18; 0.13-0.24), hypogammaglobulinemia (0.23; 0.10-0.55), concomitant chemotherapy (0.48; 0.29-0.78) and immunosuppression (0.18; 0.13-0.25). Complete remission of underlying hematologic malignancy (2.55; 1.05-6.17) and myeloablative conditioning (1.72; 1.30-2.28) compared with reduced-intensity conditioning were associated with antispike seropositivity. Ongoing immunosuppression (0.31; 0.10-0.99) was associated with poor cellular immunogenicity. In conclusion, attenuated humoral and cellular immune responses to mRNA SARS-CoV-2 vaccination are associated with several risk factors among HSCT recipients. Optimizing individualized vaccination and developing alternative COVID-19 prevention strategies are warranted.
