Factitious disorder imposed on self: A retrospective study of 2232 cases from health insurance databases

OBJECTIVE

Patients with factitious disorder imposed on self (FDIS) seek medical care for deliberately falsified problems. Although a large amount of work has been published, the scientific literature lacks robust data on FDIS. The present study aimed to estimate the annual mean of in-hospital FDIS codings in France, describe the sociodemographic characteristics of subjects with FDIS, assess healthcare utilisation and medical nomadism, and describe the pathologies most frequently associated with FDIS.

METHOD

Subjects with at least one coding of FDIS in French health insurance databases between January 1, 2009, and December 31, 2017 were included. Subjects younger than 18 years of age at the time of first coding were excluded from the study. Sociodemographic data of subjects and diagnoses associated with the first coding of FDIS were collected. Healthcare utilisation and medical nomadism were analysed descriptively from one year before to one year after the first FDIS coding.

RESULTS

2232 subjects were included, representing an average of 248 new in-hospital FDIS codings per year. The subjects included were 58.2% female. The mean age at diagnosis was 48.5 years. In the year following the first coding of FDIS, 1268 subjects (56.8%) were re-hospitalised at least once, including 159 (7.1%) with at least one new coding for FDIS. From one year before to one year after the first coding of FDIS, 66% of the subjects included had received at least one prescription for benzodiazepines, 58.3% for antidepressants, and 42.6% for antipsychotics.

CONCLUSIONS

Our findings bring new data working towards a better understanding of FDIS. The consumption of psychotropic drugs is particularly frequent in patients with FDIS.

1954. Immunogenicity against SARS CoV-2 ancestral strain and variants of two new COVID-19 recombinant adjuvanted vaccines compared to BNT162b2 as a third dose following two doses of BNT162b2: a single-blinded multicenter randomized controlled trial

Background

New adjuvanted recombinant protein vaccines against coronavirus disease 2019 (COVID-19) as heterologous boosters could maximize the benefits of vaccination against SARS CoV-2.

Methods

In this randomized, single-blinded, multicenter trial, adults who had received two doses of Pfizer-BioNTech mRNA vaccine (BNT162b2) 3–7 months before were randomly assigned to receive a boost of BNT162b2, Sanofi/GSK SARS-CoV-2 adjuvanted recombinant protein MV D614 (monovalent parental formulation) or SARS-CoV-2 adjuvanted recombinant protein MV B.1.351 vaccine (monovalent Beta formulation). The primary endpoint was the percentage of subjects with a ≥ 10-fold increase in neutralizing antibody titers for the Wuhan (D614) and B.1.351 (Beta) SARS-CoV-2 viral strains between D0 and D15.

Results

The percentages of participants whose neutralizing antibody titers against the Wuhan (D614) SARS-CoV-2 strain increased by a factor ≥ 10 between Day 0 and Day 15 was 55.3% (95% CI 43.4-66.7) in MV(D614) group (n=76), 76.1% (64.5-85.4) in MV(Beta) group (n=71) and 63.2% (51.3-73.9) in BNT162b2 group (n=76). These percentages were 44.7% (33.3-56.6), 84.5% (74.0-92.0) and 51.3% (39.6-63.0) for the B.1.351 (Beta) viral strain, respectively. Higher neutralizing antibodies rates against Delta and Omicron BA.1 variants were also elicited after Sanofi/GSK MV(Beta) vaccine compared to the other vaccines. Comparable reactogenicity profile was observed the three vaccines.

Conclusion

All three vaccines boosted antibodies and neutralizing response after BNT162b2 initial course. Heterologous boosting with the Sanofi/GSK SARS-CoV-2 adjuvanted recombinant protein vaccine B.1.351 (Beta formulation) provided higher neutralizing antibodies response rates against variants, including Omicron BA.1, compared with the mRNA BNT162b2 vaccine.

A descriptive, retrospective case series of patients with factitious disorder imposed on self

BACKGROUND

Despite cases of factitious disorder imposed on self being documented in the literature for decades, it appears to remain an under-identified and under-diagnosed problem. The present study aimed to explore factitious disorder imposed on self in a series of French patients.

METHODS

Patients 18 years old and over with factitious disorder imposed on self were retrospectively included by two independent reviewers according to DSM-5 criteria in Rennes University Hospital for the period 1995 to 2019. Patients were identified from a clinical data warehouse.

RESULTS

49 patients with factitious disorder imposed on self were included. Among them, 36 (73.5%) were female. The average age at diagnosis was 38.4 years. The 16 patients with a health-related profession were all female. Direct evidence of falsification was found in 20.4% of cases. Falsification was mainly diagnosed on the basis of indirect arguments: history of factitious disorder diagnosed in another hospital (12.2%), extensive use of healthcare services (22.4%), investigations that were normal or inconclusive (69.4%), inconsistent or incomplete anamnesis and/or patient refusal to allow access to outside information sources (20.4%), atypical presentation (59.2%), evocative patient behaviour or comments (32.7%), and/or treatment failure (28.6%). Dermatology and neurology were the most frequently involved specialities (24.5%). Nine patients were hospitalized in intensive care. Some of them received invasive treatments, such as intubations, because of problems that were only reported or feigned. The diagnosis of factitious disorder imposed on self was discussed with the patient in 28 cases (57.1%). None of them admitted to making up the disorder intentionally. Two suicide attempts occurred within 3 months after the discussion of the diagnosis. No deaths were recorded. 44.9% of the patients returned to the same hospital at least once in relation to factitious disorder imposed on self.

CONCLUSIONS

The present study reinforces data in favour of a predominance of females among patients with factitious disorder imposed on self. This diagnosis is difficult and is based on a range of arguments. While induced cases can be of low severity, cases that are only feigned can lead to extreme medical interventions, such as intubation.

Gender inequality among medical, pharmaceutical and dental practitioners in French hospitals: Where have we been and where are we now?

INTRODUCTION

Women are under-represented in senior academic and hospital positions in many countries. The authors aim to assess the place and the evolution of all appointed female and male health practitioners' working in French public Hospitals.

MATERIALS AND METHODS

Data of this observational study were collected from the National Management Centre (Centre National de Gestion) from 2015 up to January 1, 2020. First, the authors described demographic characteristics and specialties of all appointed medicine, pharmacy, and dentistry doctors' working as Hospital Practitioners, Associate Professors, and Full Professors in French General and University-affiliated Hospitals in 2020. Then, they retrospectively reported the annual incidence of new entrance according to gender and professional status from 1999 to 2019 thanks to the appointment date of all practitioners in activity between 2015 and 2020.

RESULTS

In 2020, 51 401 appointed practitioners (49.7% of female) were in activity in French public hospitals with a large majority being medical doctors (92.4%) compared to pharmacists (6%) and dentists (1.6%). Women represented 52.5% of the Hospital Practitioners, 48.6% of the Associate Professors, and 22.0% of the Full Professors (p < 0.001). There were disparities between the rates of female Full Professors in medicine (20.6%), pharmacy (36.1%), and dentistry (44.3%, p < 0.001). Women were appointed Hospital Practitioners and Associate Professors earlier than men (respectively 37.1 versus 38.8 years, p < 0.001 and 36.1 versus 36.5 years, p = 0.04), and at a later age among Full Professors (43.7 versus 41.9 years, p < 0.001). Compared to men, the annual proportion of appointed women varied significantly between 1999 and 2019 from 47.6% to 60.4% for Hospital Practitioners, from 50.0% to 44.6% for Associate Professors, and from 11.2% to 33.3% for Full Professors (p < 0.001 for trend).

CONCLUSIONS

Although more and more women occupy positions in French hospitals, there is still a gender gap regarding access to Full Professor status in medicine and pharmacy, but not in dentistry. The disparity in numbers makes comparison difficult. Despite a trend towards gender equality during the last twenty years, it has not yet been achieved regarding access to the highest positions.

Vasculitis associated with myelodysplastic syndrome and chronic myelomonocytic leukemia: French multicenter case-control study

INTRODUCTION

Our objective was to evaluate characteristics, treatment and outcome of vasculitis associated with myelodysplastic syndrome (MDS) and chronic myelomonicytic leukemia (CMML) PATIENTS AND METHODS: Retrospective descriptive analysis of MDS/CMML-related vasculitis and comparison with MDS/CMML patients without dysimmune features.

RESULTS

Seventy patients with vasculitis and MDS/CMML were included, with median age of 71.5 [21-90] years and male/female ratio of 2.3. Vasculitis was diagnosed prior to MDS/CMML in 31 patients (44%), and after in 20 patients. In comparison with MDS/CMML without autoimmune/inflammatory features, vasculitis with MDS/MPN showed no difference in MDS/CMML subtypes distribution nor International Prognostic Scoring System and CMML-specific prognostic (IPSS/CPSS) scores. Vasculitis subtypes included Giant cell arteritis in 24 patients (34%), Behçet's-like syndrome in 11 patients (20%) and polyarteritis nodosa in 6 patients (9%). Glucocorticoids (GCs) were used as first-line therapy for MDS/CMML vasculitis in 64/70 patients (91%) and 41 (59%) received combined immunosuppressive therapies during the follow-up. After a median follow-up of 33.2 months [1-162], 31 patients (44%) achieved sustained remission. At least one relapse occurred in 43 patients (61%). Relapse rates were higher in patients treated with conventional Disease Modifying Anti-Rheumatic Drug (DMARDs) (odds ratio 4.86 [95% CI 1.38 - 17.10]), but did not differ for biologics (odds ratio 0.59 [95% CI 0.11-3.20]) and azacytidine (odds ratio 1.44 [95% CI 0.21-9.76]) than under glucocorticoids. Overall survival in MDS/CMML vasculitis was not significantly different from MDS/CMML patients without autoimmune/inflammatory features (p = 0.5), but acute leukemia progression rates were decreased (log rank <0.05).

CONCLUSION

This study shows no correlation of vasculitis diagnoses with subtypes and severity of MDS/CMML, and no significant impact of vasculitis on overall survival. Whereas conventional DMARDs seem to be less effective, biologics or azacytidine therapy could be considered for even low-risk MDS/CMML vasculitis.

Intoxication with 3-MeO-PCP alone: A case report and literature review

RATIONALE

3-Methoxyphencyclidine (3-MeO-PCP) is a new psychoactive substance derived from phencyclidine. Although it can lead to severe intoxications, the main manifestations and optimal management have not been well characterized. Here, we report 2 cases of 3-MeO-PCP intoxication in the same patient, and summarize the manifestations of this intoxication reported in literature.

PATIENT CONCERNS

A 17-year-old male purchased a bag of 3-MeO-PCP on the Internet but took an oral dose (200 mg) that corresponds to the less active isomer 4-MeO-PCP. He developed high blood pressure (158/131 mm Hg), tachycardia (100 bpm), and neurological manifestations (confusion, hypertonia, nystagmus, and then agitation). A maculopapular rash appeared, although this may have been related to the administration of midazolam. Hyperlactatemia (2.6 mmol/L) was the main laboratory finding. Seven days later, he returned to the emergency department after sniffing 50 mg of 3-MeO-PCP. High blood pressure, tachycardia, and neurological manifestations (psychomotor impairment and dysarthria) were present but less severe than after the first intoxication.

DIAGNOSIS

In the first intoxication, the blood and urine 3-MeO-PCP concentrations were, respectively, 71.1 ng/mL and 706.9 ng/mL. Conventional toxicity tests were all negative. In the second intoxication, biological samples were not available.

INTERVENTIONS

In the first intoxication, treatment consisted of intravenous hydration and midazolam. The patient was transferred to an intensive care unit for monitoring. After the second intoxication, he was monitored for 12 hours.

OUTCOMES

The patient's condition improved quickly in both cases.

LESSONS

These cases provide additional information on the manifestations of 3-MeO-PCP intoxication. These manifestations are mainly cardiovascular (high blood pressure, tachycardia) and neurological. The fact that second (50 mg) intoxication was less severe than the first (200 mg) is suggestive of a dose-effect relationship for 3-MeO-PCP. The first case also emphasizes the risk of dosing errors caused by the similarity between the names "3-MeO-PCP" and "4-MeO-PCP."
