Personal and professional quality of life among French health care workers during the first COVID-19 wave: a cross-sectional study

BACKGROUND

We aimed to assess the personal and professional quality of life changes among health care workers of different professions during the COVID-19 pandemic in a large French university hospital. Other published data originated from countries with different health care systems and outbreak dynamics.

METHODS

All health care workers from our hospital were invited to fill-in an anonymous e-questionnaire of 71 questions regarding perceived personal, professional and overall quality of life before and during the first COVID-19 wave, general profile, occupation and job characteristics, change of assignment, COVID-care features if relevant, general perception during the first wave, and personal experience of being encouraged or stigmatised.

RESULTS

There were 794 participants, with a majority of nursing professionals (n = 416, 56%), including 57 nurse managers, 243 nurses, and 116 nurse assistants. Other participants were physicians (n = 188) and other health care staff (n = 140). Before the crisis, professional quality of life was low (6.5 on a 10-point scale) overall. The personal quality of life was higher (8.1) particularly for physicians and nurse managers. The COVID crisis saw a marked decrease in the personal quality of life (- 1.7), more pronounced in younger health care workers. Professional quality of life was less affected (- 0.4) and stayed almost constant for physicians. Staff in COVID units had a more positive perception of the crisis but experienced more fatigue, which resulted in similar quality of life levels in COVID and non-COVID units. Encouragements originated more often from relatives or colleagues than hospital managers and were exceptionally common: 63.4% of all participants, from 50.5% for other staff to 71.3% for physicians (p = 0.0005). Stigmatisation was reported by 19.3% of participants, with a higher proportion (p = 0.0001) among nurses (26.3%) and assistant nurses (23.3%) than among physicians (8.5%). From multivariate analysis, higher age, working as a physician and receiving encouragements were independently associated with lower loss of overall quality of life.

CONCLUSIONS

The resilience of health care workers was high overall during the first COVID wave although the quality of life decreased more among nursing staff. Social support in the form of encouragements is a key part of management, particularly in times of crisis.

Conclusion

Rituximab is an effective treatment in patients with pemphigus vulgaris and demonstrates a steroid-sparing effect

BACKGROUND

Corticosteroids (CS) with or without adjuvant immunosuppressant agents are standard treatment for pemphigus vulgaris (PV). The efficacy of adjuvant therapies in minimizing steroid-related adverse events (AEs) is unproven.

OBJECTIVES

To utilize data collected in a French investigator-initiated, phase III, open-label, randomized controlled trial to demonstrate the efficacy and safety of rituximab and seek approval for its use in PV.

METHODS

This was an independently conducted post hoc analysis of the moderate-to-severe PV subset enrolled in the Ritux 3 study. Patients were randomized to rituximab plus 0·5 or 1·0 mg kg-1 per day prednisone tapered over 3 or 6 months, or 1·0 or 1·5 mg kg-1 per day prednisone alone tapered over 12 or 18 months, respectively (according to disease severity). The primary end point was complete remission at month 24 without CS (CRoff) for ≥ 2 months, and 24-month efficacy and safety results were also reported.

RESULTS

At month 24, 34 of 38 patients (90%) on rituximab plus prednisone achieved CRoff ≥ 2 months vs. 10 of 36 patients (28%) on prednisone alone. Median total cumulative prednisone dose was 5800 mg in the rituximab plus prednisone arm vs. 20 520 mg for prednisone alone. Eight of 36 patients (22%) who received prednisone alone withdrew from treatment owing to AEs; one rituximab-plus-prednisone patient withdrew due to pregnancy. Overall, 24 of 36 patients (67%) on prednisone alone experienced a grade 3/4 CS-related AE vs. 13 of 38 patients (34%) on rituximab plus prednisone.

CONCLUSIONS

In patients with moderate-to-severe PV, rituximab plus short-term prednisone was more effective than prednisone alone. Patients treated with rituximab had less CS exposure and were less likely to experience severe or life-threatening CS-related AEs. What's already known about this topic? Pemphigus vulgaris (PV) is the most common type of pemphigus. Corticosteroids, a standard first-line treatment for PV, have significant side-effects. Although their effects are unproven, adjuvant corticosteroid-sparing agents are routinely used to minimize steroid exposure and corticosteroid-related side-effects. There is evidence that the anti-CD20 antibody rituximab is effective in the treatment of patients with severe recalcitrant pemphigus and in patients with newly diagnosed pemphigus. What does this study add? This study provides a more detailed analysis of patients with PV enrolled in an investigator-initiated trial. Rituximab plus prednisone had a steroid-sparing effect and more patients achieved complete remission off prednisone. Fewer patients experienced grade 3 or grade 4 steroid-related adverse events than those on prednisone alone. This collaboration between academia and industry, utilizing independent post hoc analyses, led to regulatory authority approvals of rituximab in moderate-to-severe PV.

First-line rituximab combined with short-term prednisone versus prednisone alone for the treatment of pemphigus (Ritux 3): a prospective, multicentre, parallel-group, open-label randomised trial

BACKGROUND

High doses of corticosteroids are considered the standard treatment for pemphigus. Because long-term corticosteroid treatment can cause severe and even life-threatening side-effects in patients with this disease, we assessed whether first-line use of rituximab as adjuvant therapy could improve the proportion of patients achieving complete remission off-therapy, compared with corticosteroid treatment alone, while decreasing treatment side-effects of corticosteroids.

METHODS

We did a prospective, multicentre, parallel-group, open-label, randomised trial in 25 dermatology hospital departments in France (Ritux 3). Eligible participants were patients with newly diagnosed pemphigus aged 18-80 years being treated for the first time (not at the time of a relapse). We randomly assigned participants (1:1) to receive either oral prednisone alone, 1·0 or 1·5 mg/kg per day tapered over 12 or 18 months (prednisone alone group), or 1000 mg of intravenous rituximab on days 0 and 14, and 500 mg at months 12 and 18, combined with a short-term prednisone regimen, 0·5 or 1·0 mg/kg per day tapered over 3 or 6 months (rituximab plus short-term prednisone group). Follow-up was for 3 years (study visits were scheduled weekly during the first month of the study, then monthly until month 24, then an additional visit at month 36). Treatment was assigned through central computer-generated randomisation, with stratification according to disease-severity (severe or moderate, based on Harman's criteria). The primary endpoint was the proportion of patients who achieved complete remission off-therapy at month 24 (intention-to-treat analysis). This study is registered with ClinicalTrials.gov, number NCT00784589.

FINDINGS

Between May 10, 2010, and Dec 7, 2012, we enrolled 91 patients and randomly assigned 90 to treatment (90 were analysed; 1 patient withdrew consent before the random assignment). At month 24, 41 (89%) of 46 patients assigned to rituximab plus short-term prednisone were in complete remission off-therapy versus 15 (34%) of 44 assigned to prednisone alone (absolute difference 55 percentage points, 95% CI 38·4-71·7; p<0·0001. This difference corresponded to a relative risk of success of 2·61 (95% CI 1·71-3·99, p<0·0001), corresponding to 1·82 patients (95% CI 1·39-2·60) who would need to be treated with rituximab plus prednisone (rather than prednisone alone) for one additional success. No patient died during the study. More severe adverse events of grade 3-4 were reported in the prednisone-alone group (53 events in 29 patients; mean 1·20 [SD 1·25]) than in the rituximab plus prednisone group (27 events in 16 patients; mean 0·59 [1·15]; p=0·0021). The most common of these events in both groups were diabetes and endocrine disorder (11 [21%] with prednisone alone vs six [22%] with rituximab plus prednisone), myopathy (ten [19%] vs three [11%]), and bone disorders (five [9%] vs five [19%]).

INTERPRETATION

Data from our trial suggest that first-line use of rituximab plus short-term prednisone for patients with pemphigus is more effective than using prednisone alone, with fewer adverse events.

Soluble alpha-enolase activates monocytes by CD14-dependent TLR4 signalling pathway and exhibits a dual function

Rheumatoid arthritis (RA) is the most common form of chronic inflammatory rheumatism. Identifying auto-antigens targeted by RA auto-antibodies is of major interest. Alpha-enolase (ENO1) is considered to be a pivotal auto-antigen in early RA but its pathophysiologic role remains unknown. The main objective of this study was to investigate the in vitro effects of soluble ENO1 on peripheral blood mononuclear cells (PBMC) from healthy donors and RA patients in order to determine the potential pathogenic role of ENO1. ELISA, transcriptomic analysis, experiments of receptor inhibition and flow cytometry analysis were performed to determine the effect, the target cell population and the receptor of ENO1. We showed that ENO1 has the ability to induce early production of pro-inflammatory cytokines and chemokines with delayed production of IL-10 and to activate the innate immune system. We demonstrated that ENO1 binds mainly to monocytes and activates the CD14-dependent TLR4 pathway both in healthy subjects and in RA patients. Our results establish for the first time that ENO1 is able to activate in vitro the CD14-dependent TLR4 pathway on monocytes involving a dual mechanism firstly pro-inflammatory and secondly anti-inflammatory. These results contribute to elucidating the role of this auto-antigen in the pathophysiologic mechanisms of RA.

Role of toll-like receptor 4 in the inflammation reaction surrounding silicone prosthesis

The inflammation which occurs around the silicone prosthesis is a complex process that can provoke the failure of the device and compromise the health of the implanted patient. Toll-like receptors (TLRs), which are transmembrane proteins, are now known to act in the innate immune response and in endogenous inflammation. The aim of our study was to assess the role of TLR4 in the foreign body reaction to a silicone shell prosthesis. Disks of shell silicone prosthesis were implanted in the subcutaneous tissue of C57BL6-TLR4-/- and C57BL6-WT mice. At day 14, inflammatory cell infiltrate and vessel sections around the prosthesis were less numerous in TLR4-/- than in WT mice. A histomorphometric analysis showed that the capsule around the implant was 1.96-fold less thick in depleted TLR4 than in wild-type mice. In addition, vascular endothelial growth factor and transforming growth factor 1 were underexpressed in the surrounding tissue of the prosthesis in TLR4-/- mice. Our study suggests, from this foreign body response model against silicone in mice, that TLR4 plays a key role in the reaction process around silicone implants.

Novel serum markers of fibrosis progression for the follow-up of hepatitis C virus-infected patients

Liver biopsy is considered the gold-standard method for the assessment of liver fibrosis during follow-up of hepatitis C virus-infected patients, but this invasive procedure is not devoid of complications. The aim of the present study was to identify novel non-invasive markers of fibrosis progression. By microarray analysis, we compared transcript levels in two extreme stages of fibrosis from 16 patients. Informative transcripts were validated by real-time PCR and used for the assessment of fibrosis in 23 additional patients. Sixteen transcripts were found to be dysregulated during the fibrogenesis process. Among them, some were of great interest because their corresponding proteins could be serologically measured. Thus, the protein levels of inter-alpha inhibitor H1, serpin peptidase inhibitor clade F member 2, and transthyretin were all significantly different according to the four Metavir stages of fibrosis. In conclusion, we report here that dysregulation, at both the transcriptional and protein levels, exists during the fibrogenesis process. Our description of three novel serum markers and their potential use as serological tests for the non-invasive diagnosis of liver fibrosis open new opportunities for better follow-up of hepatitis C virus-infected patients.
