RESUMO

BACKGROUND: The aim of this study was to evaluate the efficacy and safety of ferric carboxymaltose in rheumatic patients with iron deficiency anaemia. MATERIALS AND METHODS: The study retrospectively evaluated a cohort of 34 patients with iron deficiency anaemia affected by inflammatory rheumatic diseases that are refractory or intolerant to oral iron therapy. They were treated with ferric carboxymaltose for a total of 56 cycles of treatment. The primary end point was to evaluate the increase of haemoglobin after ferric carboxymaltose treatment. The secondary end point was safety, including the occurrence of disease flare. RESULTS: Median age of the cohort was 60 years (range 31-91 years), with a male/female ratio of 4/30. Nine (26.5%) were affected by rheumatoid arthritis, 10 (29.4%) by spondyloarthritis, and 15 (44.1%) by other autoimmune connective tissue diseases. Median time from diagnosis was 7 years (IQR 2-12). At time of treatment (T0), median haemoglobin was 9.3 g/dL (IQR 8.2-10.3), transferrin saturation 6.2% (IQR 3.8-9.8), and ferritin 8.5 ng/mL (IQR 6.0-12.8). Median ferric carboxymaltose dose was 1,000 mg. At 6 weeks from T0, median haemoglobin was 12.3 g/dL (IQR 11.6-13.3), with a mean increase of 3.0 g/dL (p<0.01). Twelve (35.3%) patients needed re-treatment with ferric carboxymaltose for recurrence of iron deficiency anaemia. Four (4.3%) patients developed mild grade side effects. One suspected flare reaction has been observed. DISCUSSION: In patients affected by inflammatory rheumatic diseases, ferric carboxymaltose is safe and effective in correcting iron deficiency anaemia.

RESUMO

BACKGROUND AND OBJECTIVES: The role of pre-donation blood pressure (BP) as independent contributor to post-donation vasovagal reactions (VVRs) is still debated. Differences between a liberal (i.e., inclusion of hypotensive donors) and a restrictive policy (i.e., not accepting hypotensive donors) should be investigated. This study aims to investigate the consequences of a liberal policy in development of VVRs after whole-blood donations. MATERIALS AND METHODS: We compared the incidence of VVRs between 2015 (restrictive policy) and 2016 (liberal policy) and the associated risk factors. We evaluated respectively 22 789 vs. 21 676 blood donations obtained from 18 001 blood donors (12 501 donated in both years). RESULTS: Comparing the results we obtained between 2015 and 2016, donations showed an overlap of the cohorts. Two hundred fifteen VVRs (incidence rate 0·48%) were observed, 104 (0·46%) of which in 2015, and 111 (0·51%) in 2016. A preliminary univariate analysis showed that donors with systolic BP <110 mm Hg had a two-fold risk of VVRs compared to normotensive donors (VVR/donation rate of 0·99% vs. 0·46%; P = 0·001). The subsequent multivariable logistic regression model showed that VVRs were highly associated with weight, site of collection, age and number of donations, excluding a role for systolic and diastolic BP. CONCLUSION: A liberal pre-donation BP policy seems to be safe for blood donors. Our analysis confirms that older donors with higher body-weight who already had donated blood are unlikely to experience VVRs.

RESUMO

Graft-versus-host disease (GvHD) causes severe mucositis, impairs feeding and favors infection. The objective of this study was to identify the impact of GvHD in the oral cavity. We reviewed all consecutive patients who developed oral GvHD after HSCT. The study period was over 14 years. 53 patients were identified. M/F = 1.4; median age was 48.6 years; the median follow-up was for up to 3 years and 6 months. Conditioning regimens included several drugs (e.g., busulfan, cyclophosphamide and fludarabine). In 11 cases, radiotherapy (RT) was also used. Patients treated with RT were more likely to have tooth decay requiring fillings (p = 0.029), to need canal root interventions (p = 0.005) and to have tartar requiring oral hygiene interventions (p = 0.011). Patients with a lymphoma diagnosis were more likely to develop perioral scleroderma and chronic oral GvHD (cGvHD) (p = 0.045). Oral acute GvHD (aGvHD) was seen in 26 patients (49.1%). 21 (39.6%) patients developed cGvHD. GvHD of the tongue was seen in 21 (40%) patients. Oral mucositis was seen in only 5 patients (9.4%). Conditioning regimens with RT are more likely to induce oral aGvHD. The tongue is often affected by GvHD.

RESUMO

CONCLUSIONS: The increase of immunization against blood group antigens has reinforced the need for automated extensive blood typing. The aim of this study was to assess both the validity and reliability of red blood cell (RBC) automated agglutination technology in testing for antigens of Kidd (Jk), Duffy (Fy), and MNS (Ss) blood systems. ORTHO Sera (Ortho Clinical Diagnostics, Raritan, NJ) anti-Jka, anti-Jkb, Anti-Fya, anti-Fyb, anti-S, and anti-s reagents were each tested on RBC samples previously typed. Replicates were performed on three separate testing sessions with three consecutive repetitions within each session, thus obtaining 486 test results. Accuracy was assessed by aggregate analysis of sensitivity, specificity, and area under the receiver operating characteristics curve (AUC). Reliability was estimated by a cross-classified mixed-effect logistic model. All reagents tested yielded optimal accuracy (100% for sensitivity and specificity, and 1.00 for AUC), except for anti-S, for which performance was slightly lower (98%, 100%, and 0.99, respectively), owing to misclassification of one sample in a single replicate. Anomalous automated measurements were recorded in 38 of 486 tests (7.8%), which then needed additional manual interpretation. Different sessions and samples were the major contributors to measurement failures (38% and 18%, separately). Order of repetitions and antigen specificity across replicates did not contribute to the risk of failures, although weak evidence of enhanced risk was observed with Jk testing. Automated RBC typing with ORTHO Sera reagents against antigens in the Kidd, Duffy, and MNS blood group systems displayed nearly 100 percent accuracy. However, a sizable number of replicates needed additional ad hoc interpretation, thus suggesting that the reliability could still be improved. Automated agglutination technology represents a viable option for phenotyping large volumes of samples.

RESUMO

BACKGROUND: The aim of this study was to evaluate the effectiveness of ferric carboxymaltose (FCM) in patients with iron deficiency anemia (IDA) secondary to gastrointestinal chronic blood loss (CBL), who received chronic transfusion support. STUDY DESIGN AND METHODS: We retrospectively evaluated 38 patients with IDA (hemoglobin [Hb] < 10 g/dL and ferritin < 12 ng/mL or transferrin saturation [TSAT] < 16%) refractory or intolerant to oral iron therapy that necessitated transfusion support in the previous 12 months. They were treated with FCM (500-2500 mg). The primary endpoint was to evaluate the reduction of transfusion requirements (red blood cell [RBC] units) after FCM treatment. RESULTS: The median age of the cohort was 78 years, with a male:female ratio of 22:16. Before FCM treatment a median of 6 RBC units had been transfused. At the treatment (T0) the median value of Hb was 8.7 g/dL, the TSAT 6%, and ferritin 12 ng/mL. The median FCM dose was 1000 mg. At 5 weeks from T0 the median Hb level was 11 g/dL, with a median increase of 2.4 g/dL. With a median follow-up of 326 days, the median transfusion requirement was 0 RBC units, significantly lower than before T0 (p < 0.001). Overall 17 patients still necessitated transfusion support. Twenty-three patients needed retreatment with FCM for recurrence of IDA: 10 of them obtained a response again. The percentage of transfusion-independent patients at median follow-up was equal to 52%. CONCLUSION: In patients with IDA secondary to CBL, FCM significantly reduces the need of transfusions and achieves transfusion independence in half of the cases.

RESUMO

PURPOSE: A proliferation-inducing ligand (APRIL), a tumor necrosis factor superfamily member involved in B-lymphocytes differentiation and survival, plays a role in protecting B-Cell Chronic lymphocytic leukemia (B-CLL) cells from apoptosis. Having observed that APRIL serum (sAPRIL) levels were higher in B-CLL patients with CLL at diagnosis as compared to healthy donors (14.61±32.65 vs. 4.19±3.42 ng/mL; P<0.001), we tested the correlation existing in these patients between sAPRIL, clinical-biological parameters and disease progression. EXPERIMENTAL DESIGN: sAPRIL levels were measured by ELISA in 130 patients with B-CLL at diagnosis and in 25 healthy donors. RESULTS: sAPRIL levels did not correlate with gender, age, clinical stage, blood cell counts, ß2-microglobulin (ß2M) levels, ZAP-70 and CD38 expression. Using median sAPRIL natural logarithm (ln) as cutoff, we distinguished two groups of patients (APRIL(LOW) and APRIL(HIGH) ) who were comparable with regard to clinical-biological parameters and overall survival, but different with regard to time to the first treatment (TTFT; P=0.035). According to univariate analysis, high lymphocyte count, high ß2M, Binet stage B-C, ZAP-70 expression and ln(sAPRIL) above median were associated with earlier TTFT. Advanced clinical stage, high ß2M, ZAP-70 expression and ln(sAPRIL) above median remained independently predictive of shorter TTFT at multivariate analysis. Moreover, sAPRIL increased its prognostic significance when patients were stratified according to independent favorable clinical-biological characteristics (low ß2M, stage A and lack of ZAP-70 expression). CONCLUSIONS: sAPRIL is a novel indicator of shorter TTFT in B-CLL and a predictor of progression especially in patients otherwise considered at low risk according to validated prognostic factors.
