RESUMO
OBJECTIVE: Monocyte count and red cell distribution width (RDW) have shown prognostic potential in patients with fibrotic lung diseases. Their kinetics and prognostic usefulness of peripheral blood indices in patients with interstitial lung diseases (ILDs) undergoing surgical lung biopsy for diagnostic reasons have not been studied. PATIENTS AND METHODS: We retrospectively included consecutive patients with ILD who underwent surgical lung biopsy for diagnostic purposes Between 07/11/2019 and 11/10/2022. RESULTS: Fifty-five (n=55) patients were included in the study. Median age was 65.0 years (95% CI: 63.0 to 66.0). Postoperative peripheral blood monocyte count on Day 1 was significantly higher compared to preoperative, perioperative, and postoperative values on Day 90 (repeated measures ANOVA, p<0.0001). Patients in the high postoperative monocyte count group had significantly increased length of postoperative hospital stay [Mann-Whitney test, p=0.007] and significantly lower Forced Vital Capacity (FVC)% predicted 3 months after surgery [Mann-Whitney test, p=0.029] compared to patients in the low postoperative monocyte count group. Postoperative RDW on Day 90 was significantly higher compared to preoperative, perioperative and postoperative-Day 1 RDW (repeated measures ANOVA, p=0.008, p=0.006, p<0.0001, respectively). Patients in the high postoperative RDW group did not have increased hospital stay (Mann-Whitney test, p=0.49) or decreased FVC% predicted at 3 months compared to patients in the low postoperative RDW group (Mann-Whitney test, p=0.91). CONCLUSIONS: Peripheral blood monocyte count could be a prognostic biomarker for patients with ILDs undergoing diagnostic surgical lung biopsies. RDW does not seem to represent an acute phase biomarker but seems to increase over time following disease progression. Larger studies are urgently required.

OBJECTIVE: Real-life data for vaccination against COVID-19 are sorely needed. This was a population-based analysis aiming at investigating the hospitalization risk for COVID-19 of 98,982 subjects and compare features of vaccinated and unvaccinated patients. PATIENTS AND METHODS: Hospitalized patients with COVID-19 between 01/07/2021 and 11/02/2022 were included in the study. RESULTS: 582 patients were included in the analysis [males: 58.6% (n=341), vaccinated patients: 28.5% (n=166), unvaccinated patients: 71.5% (n=416)]. Median age of vaccinated patients was significantly higher compared to median age of unvaccinated [74.0 (95% CI: 72.0-77.0) vs. 59.0 (95% CI: 57.0-62.0), p=0.0001]. Mean latency time (±SD) from the second dose to hospitalization was 5.7±2.6 months. Between 01/07/2021 and 01/12/2021, unvaccinated subjects had higher risk for hospitalization compared to vaccinated [HR: 2.82, 95% CI: 2.30-3.45, p<0.0001]. Between 02/12/2021 and 11/02/2022, unvaccinated subjects presented with higher risk for hospitalization than subjects that had received booster dose [HR: 2.07, 95% CI: 1.44-2.98, p=0.005], but not than subjects that got two doses. Median value of hospitalization days was higher in unvaccinated patients compared to vaccinated [7.0 (95% CI: 7.0-8.0) vs. 6.0 (95% CI: 5.0-7.0), p=0.02]. Finally, age-adjusted analysis showed that hospitalized unvaccinated patients presented with significantly higher mortality risk compared to hospitalized vaccinated patients [HR: 2.59, 95% CI: 1.69-3.98, p<0.0001]. CONCLUSIONS: Vaccination against COVID-19 remains the best way to contain the pandemic. There is an amenable need for booster dose during the omicron era.

Serum ferritin concentration was assessed in male and female pregnant and non-pregnant thalassaemia carriers and in normal subjects of both sexes. Low ferritin levels were found in 61% of non-pregnant and in 32% of pregnant female beta-thalassaemia heterozygotes whereas male thalassaemia carriers had normal iron stores. Increased ferritin levels were not observed in any of the subjects examined. These findings show that iron deficiency is a common finding in female thalassaemia carriers of reproductive age who are not receiving iron supplementation.
