The True Story on Deficiencies After Sleeve Gastrectomy: Results of a Double-Blind RCT

Background: Since a few years, the laparoscopic sleeve gastrectomy (SG) has become the most performed bariatric operation worldwide. However, as with all bariatric procedures, SG also leads to vitamin and mineral deficiencies post-operatively and standard multivitamin supplements are probably not sufficient. Objective: The present study evaluates the effectiveness of a specialized multivitamin supplement for SG patients (WLS Optimum 1.0, FitForMe, Rotterdam, the Netherlands), compared to a standard multivitamin supplement (sMVS). Design: A double-blind randomized controlled trial was performed. For 12 months, patients in the intervention group received WLS Optimum, containing elevated doses of multiple vitamins and minerals. Patients in the control group were provided with sMVS, containing 100% of the recommended dietary allowance. Results: In total, 139 patients were available for analysis (WLS Optimum, n = 69; sMVS, n = 70). Intention-to-treat analyses revealed more folic acid deficiencies and higher serum vitamin B1 levels in the WLS Optimum group. Per protocol analyses showed that in patients using WLS Optimum, serum folic acid and vitamin B1 levels were higher, serum PTH levels were lower, and only one patient (2.6%) was anemic compared to 11 patients (17.5%) using a sMVS (p < 0.05 for all). No differences were found in prevalence of deficiencies for iron, vitamin B12, vitamin D, and other vitamins and minerals. Conclusions: This optimized multivitamin supplement only affected serum levels of folic acid, PTH and vitamin B1, and anemia rates compared to a sMVS. There is a clear need to further optimize multivitamin supplementation for SG patients. Besides, non-compliance with multivitamin supplements remains an important issue that should be dealt with. Clinical Trial Registry: The study protocol was registered at the clinical trials registry of the National Institutes of Health (ClinicalTrials.gov; identifier NCT01609387).</p

Long Term Follow-up Data and Health-Related Quality of Life in Frontline Therapy of Fit Patients Treated With FCR Versus BR (CLL10 Trial of the GCLLSG)

Fludarabine, cyclophosphamide and rituximab (FCR) was compared to bendamustine and rituximab (BR) in an international, randomized, open label, phase 3 trial in 561 previously untreated, fit patients with chronic lymphocytic leukemia (CLL) without del (17p). Primary endpoint was progression free survival (PFS). The final primary endpoint analysis after 37.1 months median follow up failed to show the non-inferiority of BR as compared with FCR. With extended median follow up of 58.2 months, median PFS was 42.3 months in BR-treated patients versus 57.6 months for FCR-treated patients (Hazard Ratio [HR] 1.593; 95% CI 1.271-1.996; p 65 years, median PFS was 48.5 months with BR versus 57.9 months with FCR without reaching statistical significance (HR 1.352; 95% CI 0.912-2.006; p = 0.134). Median OS was not reached for both arms with 5-year OS rates of 80.1% vs 80.9%, respectively (HR 1.108; 95% CI 0.755-1.627; p = 0.599). No statistically significant difference was found in the time to secondary malignancy between the 2 groups (at 5 years, 86.6% free from secondary malignancies in the BR group vs 83.8% in the FCR group [HR 0.801; 95% CI 0.507-1.267; p = 0.344]). In patients >65 years secondary neoplasia occurred more frequently after FCR treatment [28 of 86 (32.6%) patients] as compared with BR [18 of 107 (16.8%) patients; p = 0.011]. Health-related quality of life was similar in both treatments. Despite the improved PFS for FCR, OS did not differ. These results also suggest an increase in secondary neoplasia associated with FCR in elderly fit CLL patients
