A concurrent vitamin B12 deficiency is not well described and may be related to a rare gastrointestinal manifestation of sarcoid and Lofgren’s syndrome. We describe a case of a 57-year-old male presented with migratory polyarthritis, erythemic nodules, edema of his legs and fever. His laboratory tests showed anemia with a profound vitamin B12 deficiency. Imaging demonstrated bilateral hilar adenopathy. Pathology revealed non-necrotizing granulomas consistent with sarcoidosis. The patient was started on prednisone and vitamin B12 supplements with improvement of his complaints and vitamin B12 levels. Sarcoidosis can manifest in many extrapulmonary organs, including the gastrointestinal tract, resulting in nutritional deficiencies, such as vitamin B12 deficiency. Treatment of these nutritional deficiencies includes treatment with steroids, as well as vitamin supplementation. We suggest this case to be a rare manifestation of gastrointestinal involvement in Lofgren syndrome; however, a biopsy from the GI tract was not performed to confirm the diagnosis. An informed consent was obtained from the patient. An institutional approval was not required for the publication of this case.Keywords: vitamin B12, sarcoidosis, Lofgren’s syndrome, gastrointestinal tract

Introduction: Clostridioides difficile (CDI) is a common cause of infectious diarrhea. The current recommendation is to initiate empirical antibiotic treatment for suspected CDI who have an anticipated delay of confirmatory results or fulminant colitis. This is based on limited clinical trials. The study aims to examine the impact of early treatment on mortality and clinical outcomes., Methods: This retrospective cohort study included adult patients with CDI. Early treatment was defined as the initiation of an anti-Clostridioides medication within the first 24 h following stool sampling. Outcomes were 30 and 90 day mortality, length of hospital stay (LOS), recurrence, and colectomy rate. To address potential bias, propensity score matching followed by logistic regression was performed, P value less than 5% was considered statistically significant., Results: Study cohort consisted of 796 patients; clinical characteristics were balanced following matching. There was no difference, in favor of early treatment, between the groups regarding 30 day mortality and 90 day mortality with HR of 0.91 (95% CI 0.56-1.47) and 0.7 (95% CI 0.45-1.08), respectively. No statistically significant difference in recurrence rate, ICU admission or colectomy rate was observed. The LOS was shorter in the early-treatment group with 6 days vs. 8 days., Conclusion: Early treatment for CDI had shortened hospital stay. However, it did not affect clinical outcomes in adult patients., (© 2024. The Author(s), under exclusive licence to Società Italiana di Medicina Interna (SIMI).)

Introduction: Initiation of global vaccination significantly reduced the morbidity and mortality of COVID-19. During the Omicron wave, approximately 70% of the Israeli adult population was fully vaccinated, but the efficacy of the vaccine was questioned., Methods: We conducted a retrospective cohort study of all adult patients admitted to the COVID-19 departments in Rabin Medical Center, during the Delta wave and the Omicron wave. Patients were matched in the 2 waves using the inverse probability of treatment weighting (IPTW) method and risk for mechanical ventilation and 30-day all-cause mortality was assessed., Results: Vaccination had a significant effect on 30-day mortality in the Delta and Omicron waves with adjusted OR of 0.35 (0.17-0.70) and 0.5 (0.27-0.95) respectively. Nonetheless, the rate of mechanical ventilation was similar between the groups with OR of 0.75 (0.52-1.09) and 0.64 (0.40-1.01). Vaccination status did not change the length of admission in both waves., Conclusion: We observed a decreased risk for 30-day mortality among vaccinated patients during the Delta and Omicron waves in Israel. This association, even though consistent, was of a lesser magnitude during the Omicron wave., (Copyright © 2023 Elsevier España, S.L.U. All rights reserved.)

COVID-19 vaccines were introduced soon after the COVID-19 pandemic emerged in 2020. Various side effects were reported worldwide, including several types of common systemic side effects such as fever and general fatigue. Reports of other rare manifestations also emerged. We report the case of an adult male with a rare systemic syndrome mimicking lymphoma after he had received the first dose of an mRNA-based COVID-19 vaccine. After nearly 6 months of investigation with suspicion for an infection or malignancy, all symptoms resolved, laboratory tests normalized, and imaging showed no sign of active disease., Learning Points: A lymphoma-like reaction is a possible side effect of COVID-19 vaccination.It is important to rule out other causes of systemic symptoms before diagnosing a reaction to a COVID-19 vaccine.A lymphoma-like reaction following administration of a COVID-19 vaccine has a good prognosis., Competing Interests: Conflicts of Interests: The Authors declare that there are no competing interests., (© EFIM 2022.)

Objectives: The authors sought to collect data on contemporary practice and outcome of transcatheter aortic valve replacement (TAVR) in oncology patients with severe aortic stenosis (AS)., Background: Oncology patients with severe AS are often denied valve replacement. TAVR may be an emerging treatment option., Methods: A worldwide registry was designed to collect data on patients who undergo TAVR while having active malignancy. Data from 222 cancer patients from 18 TAVR centers were compared versus 2,522 "no-cancer" patients from 5 participating centers. Propensity-score matching was performed to further adjust for bias., Results: Cancer patients' age was 78.8 ± 7.5 years, STS score 4.9 ± 3.4%, 62% men. Most frequent cancers were gastrointestinal (22%), prostate (16%), breast (15%), hematologic (15%), and lung (11%). At the time of TAVR, 40% had stage 4 cancer. Periprocedural complications were comparable between the groups. Although 30-day mortality was similar, 1-year mortality was higher in cancer patients (15% vs. 9%; p < 0.001); one-half of the deaths were due to neoplasm. Among patients who survived 1 year after the TAVR, one-third were in remission/cured from cancer. Progressive malignancy (stage III to IV) was a strong mortality predictor (hazard ratio: 2.37; 95% confidence interval: 1.74 to 3.23; p < 0.001), whereas stage I to II cancer was not associated with higher mortality compared with no-cancer patients., Conclusions: TAVR in cancer patients is associated with similar short-term but worse long-term prognosis compared with patients without cancer. Among this cohort, mortality is largely driven by cancer, and progressive malignancy is a strong mortality predictor. Importantly, 85% of the patients were alive at 1 year, one-third were in remission/cured from cancer.
