Migrant populations face a disproportionate risk of undiagnosed HIV and viral hepatitis, posing a major challenge to elimination goals. The HEPINMIGRA study evaluated the acceptability, feasibility, and effectiveness of an integrated community-based screening program for migrants in Alicante, Spain. Between March 2024 and February 2025, nine outreach campaigns were conducted in community settings with the support of intercultural mediators. Screening was performed using finger-prick dried blood spots. Among 535 attendees, 529 migrants were screened (acceptance rate 98.9%). Participants had a median age of 39 years, 56.1% were male, and 77.9% were of African origin. Seroprevalence was 1.1% for HIV (95% CI: 0.4-2.3%), 0.6% for HCV (95% CI: 0.1-1.6%), and 4.5% for HBsAg (95% CI: 2.9-6.6%). Although most individuals with positive results were successfully contacted and linked to care, treatment initiation rates were low. Community-based DBS screening was highly feasible and effective for case detection, but major gaps were identified in linkage to care and treatment initiation.

Background/Objetives: The objective of this study was to determine the in vitro susceptibility profiles of clinical Clostridioides difficile isolates to metronidazole (MTZ), vancomycin (VAN), fidaxomicin (FDX), tigecycline (TGC), and eravacycline (ERV) in a multicenter Spanish cohort, and to evaluate their association with clinical factors. Methods: Strains were obtained from prospectively included patients in the ICD-ANCRAID-SEICV cohort (ClinicalTrials.gov ID: NCT04801862) in Andalucía and the Valencian Community between 1 January 2020 and 30 April 2023. Antimicrobial susceptibility testing was performed using E-test for MTZ, VAN, TGC, and ERV, and agar dilution for FDX. Results: The results were interpreted following EUCAST clinical breakpoints and ECOFF criteria. A total of 107 patients were included (median age 70 years; 65.4% women). Nearly half of the cases were community-acquired, 30% nosocomial, and the remainder healthcare-associated. Most infections were non-severe, and 32.7% experienced recurrence. Overall resistance levels were low: VAN and TGC each showed resistance in 2.8% of isolates, followed by MTZ (1.9%). Only one isolate was resistant to FDX (0.9%), and none to ERV. MIC90 values were low for all agents. Some resistant isolates displayed co-resistance and were recovered from patients with prior antibiotic exposure. Among the seven patients carrying resistant strains, most were women, and the cases were predominantly community-acquired. Clinical characteristics, including age, comorbidity, infection origin, and severity, did not differ from those with susceptible isolates. All patients achieved clinical cure without recurrent infection. No association was found between elevated MIC values and recurrence or greater severity. Conclusions: FDX and ERV demonstrated excellent in vitro activity. Resistance to MTZ, VAN, and TGC was uncommon but detectable. Findings highlight the need for continued antimicrobial resistance surveillance and evaluation of its potential clinical impact.

ABSTRACTBackgroundLimited data are available on the management and outcomes of postoperative Crohn's disease (CD) in older patients. We aimed to describe the management of CD in the postoperative setting and assess surgical postoperative recurrence (POR) in this population.MethodsThis was a case‐control study including all adult patients with CD from the ENEIDA registry who had undergone a first intestinal resection with ileo‐colonic anastomosis. Patients were grouped according to their age at the time of the first surgery in older (over 60 years) subjects and controls (between 18 and 60 years of age).ResultsA total of 3982 (535 older subjects and 3454 controls) underwent a first intestinal resection for CD with an ileo‐colonic anastomosis. Time from CD diagnosis to surgery was significantly longer in older patients (114 ± 128 vs. 93 ± 97 months; p < 0.001). Older patients also had a lower proportion of penetrating CD (25% vs. 39%; p < 0.0001) and perianal disease (14% vs. 25%; p < 0.0001). A significantly lower proportion of older patients started preventive therapies for POR (32% vs. 51%; p < 0.0001). The cumulative risk of surgical POR was 3.2%, 5.3% and 10.1% in the older group and 3.6%, 6.6% and 14.2% in the control group at three, five and 10 years, respectively (p = 0.093). In the multivariate logistic regression analysis, only prevention with thiopurines was associated with a lower risk of surgical POR.ConclusionsAlthough postoperative preventive therapy with immunomodulators or biologicals is prescribed less often in older patients after a first intestinal resection, they develop surgical POR as often as younger adult patients.

Hypersensitivity to chlorhexidine is rare in children. The usefulness of different diagnostic tests for allergic contact dermatitis (ACD) is unknown. We aim to describe a case series of children with hypersensitivity to chlorhexidine and to compare the results of different diagnostic tests. Nine children with hypersensitivity to chlorhexidine were included. Only six of these children and their parents consented to a comprehensive allergy assessment, which included the prick test, intradermal test, patch test, and repeated open application test (ROAT). Seven children (78%) presented symptoms of chlorhexidine hypersensitivity within the first 5 years of life; two of them before the age of 1 year. In four children, the dermatitis lesions were suggestive of wound superinfection. All six children who participated in the comprehensive diagnostic evaluation had negative results on the prick test. The immediate-reading intradermal test was positive in one case and uncertain in two cases. The patch test was positive in five cases, and the ROAT was positive in all six cases when using 2% chlorhexidine alcohol solution. ACD to chlorhexidine in children appears to be rare and can be difficult to detect. Clinicians should consider this diagnosis when wounds worsen with chlorhexidine. Although the patch test is the most standardized method for detecting ACD, the ROAT with 2% chlorhexidine alcohol solution was the most sensitive test in our patients.
