ABSTRACT

INTRODUCTION. Two-thirds of patients with COVID-19 developed smell and taste dysfunction, of whom half experienced improvement within the first month. After six months, 5-15% still suffered from significant olfactory dysfunction (OD). Before COVID-19, olfactory training (OT) was proved to be effective in patients with post-infectious OD. Therefore, the present study aimed to investigate the progress of olfactory recovery with and without OT in patients with long COVID-19. METHODS. Consecutive patients with long COVID-19 referred to the Flavour Clinic at Godstrup Regional Hospital, Denmark, were enrolled. The diagnostic set-up at the first visit and follow-up included smell and taste tests, questionnaires, ENT examination and instructions in OT. RESULTS. From January 2021 to April 2022, 52 patients were included due to long COVID-19-related OD. The majority of patients complained of distorted sensory quality, in particular, parosmia. Two-thirds of the patients reported a subjective improvement of their sense of smell and taste along with a significant decline in the negative impact on quality of life (p = 0.0001). Retesting at follow-up demonstrated a significant increase in smell scores (p = 0.023) where a minimal clinically important difference (MCID) in smell scores was found in 23% of patients. Full training compliance was significantly associated with the probability of MCID improvement (OR = 8.13;p = 0.04). CONCLUSIONS. The average effect of OT is modest;however, full training compliance was significantly associated with an increased probability of a clinically relevant olfactory improvement. FUNDING. none.

ABSTRACT

On behalf of the GRAALL group, the Czech Republic ALL group, the Finland ALL group and the EWALL group. Introduction. Treatment of older patients (pts) with B-cell precursor acute lymphoblastic leukemia (BCP-ALL) remains an unmet medical need. Inotuzumab ozogamicin (INO), an anti-CD22 antibody conjugated to calicheamicin, is approved for the treatment of relapsed/refractory BCP-ALL in adults, sinusoidal obstruction syndrome (SOS) being the major adverse event associated with INO. A previous first line study conducted by the MDACC in pts 60 years or older successfully used INO in combination with a lower intensity version of the hyper-CVAD (mini-hyper-CVD). Due to the occurrence of SOS, the total doses were fixed at 1.3 mg/m² for cycle 1 followed by 3 cycles at 1 mg/m² (Kantarjian H et al. Lancet Oncol, 2018). Here, we aimed to assess the activity and safety of fractionated INO at a reduced dosage in combination with low-intensity chemotherapy as frontline therapy for older pts with CD22+ Philadelphia chromosome-negative (Ph-neg) BCP-ALL. Methods. EWALL-INO is a single arm prospective phase 2 multicentric study conducted in European centers belonging to the EWALL group. Eligibility criteria were pts aged 55y or older, performance status ≤2, and newly diagnosed CD22+ (20% or more of positive blast cells) Ph-neg BCP-ALL without central nervous system involvement. After a prephase including 5 days (D) of dexamethasone (DEX) 10mg per D and a single intrathecal injection (IT), the induction regimen was begun and split in 2 parts. Induction part I (Induc1) consisted of one triple IT, vincristine (VCR) 2 mg (1 mg over 70y) D1 D8 D15 D22 and DEX 20 mg D1D2 D8D9 D15D16 D22D23 combined with 3 injections of INO (0.8 mg/m² D1, 0.5 mg/m² D8 and D15). Induction part II (Induc2) was offered to pts in CR or CRp (CR with platelets < 100 G/l) after Induc1 or as salvage therapy. Induc2 consisted of DEX 20mg D1D8, cyclophosphamide (CY) 300 mg/m² D1 to D3, one triple IT D2 and 2 injections of INO (0.5 mg/m² D1 and D8). Pts in CR/CRp were programmed to receive 6 blocks of consolidation (Ara-C 1.5g/m²/12h adapted to renal clearance D1D2 and DEX 10mg/12h D1D2, cycles 1 and 4;Methotrexate (MTX) 1.5 g/m² over 24h D1, VCR 1 or 2 mg D1, one triple IT D2 and 6-mercaptopurin (6-MP) D1 to D7, cycles 2 and 5;CY 500 mg/m² D1D2, VP16 75 mg/m² D1D2, one triple IT D2 and MTX 25 mg/m² D1, cycles 3 and 6) followed by a POMP maintenance (VCR, 6-MP, MTX, DEX) during 18 months. Allograft was allowed after at least 3 blocks of consolidation at the discretion of the investigators. The evaluable population was pts who received at least 1 dose of INO. Analyses were by modified intention to treat and performed JUN 28, 2021. All pts gave informed consent. The study is registered at ClinicalTrials.gov under the NCT number: NCT03249870. Results. Between DEC 29, 2017 and JUN 22, 2021, 115 pts (out of 130 planned pts) were enrolled including 6 pts with screen failure. The first 90 eligible pts (up to MAR 1, 2021) were considered for this analysis to obtain a minimum of 4 months follow-up. Median age was 69y (range 55-84) and median follow-up for alive pts was 1.18 years (range 0.3-3.5). At time of analysis, 90 and 88 pts had started induc1 and induc2, respectively. Treatment related mortality was 2.2% (2/90) and CR/CRp rate was 85.5% (77/90, 6 CRp) after induc1. Three cases relapsed between induc1 and induc2 and 5 pts were salvaged by induc2 allowing to a CR/CRp rate of 87.7% (79/90, 8 CRp) after induc2. One pts died from refractory disease during induc2. One, 2, 3 4 and 5 injections of INO were administered to 2 (2.2%), 2(2.2%), 11 (12.2%), 2 (2.2%) and 73 pts (81.1%) respectively. Only 6 pts were allografted. One-year OS was estimated to be 78.5% (95%CI 68-85.9) and median OS was not reached. One-year relapse free survival was 74.5% (95CI 63.5-82.6) (Figure 1). Grade 3-4 liver toxicity was observed in 8 pts (8.8%) during the study including 3 pts (3.3%) developing SOS, 2 related to INO during induc1 and one occurred after transplant. Twenty-nine pts died during the follow-up, 16 from relapses (overall incidence 18%) and 13 from adverse events (overall incidence 14.4%), including one COVID19 fatal infection during consolidation. Conclusion. Fractionated inotuzumab ozogamicin at reduced doses (0.8/0.5/0.5/0.5 mg/m²) combined with low-intensity chemotherapy is a very active and well tolerated frontline therapy for older patients with CD22+ Ph-neg BCP-ALL.
