RESUMO

BACKGROUND: Patients with pre-existing mental disorders are at higher risk for SARS-CoV-2 infection and adverse outcomes, and severe mental illness, including mood and psychosis spectrum disorders, is associated with increased mortality risk. Despite their increased risk profile, patients with severe mental illness have been understudied during the pandemic, with limited estimates of exposure in inpatient settings. OBJECTIVE: The aim of this study was to describe the SARS-CoV-2 seroprevalence and antibody titers, and pro-inflammatory cytokine concentrations of newly admitted or hospitalized psychiatric inpatients without known history of COVID-19 infection, using robust quantitative multi-antigen assessments, and compare patients' exposure to that of hospital staff. METHODS: This multi-centric, cross-sectional study compared SARS-CoV-2 seroprevalence and titers of 285 patients (University Psychiatric Centre Duffel [UPCD] N = 194; Assistance-Publique-Hopitaux de Paris [AP-HP] N = 91), and 192 hospital caregivers (UPCD N = 130; AP-HP N = 62) at two large psychiatric care facilities between January 1st and the May 30th 2021. Serum levels of SARS-CoV-2 antibodies against Spike proteins (full length), spike subunit 1 (S1), spike subunit 2 (S2), spike subunit 1 receptor binding domain (S1-RBD) and Nucleocapsid proteins were quantitatively determined using an advanced capillary Western Blot technique. To assess the robustness of the between-group seroprevalence differences, we performed sensitivity analyses with stringent cut-offs for seropositivity. We also assessed peripheral concentrations of IL-6, IL-8 and TNF-a using ELLA assays. Secondary analyses included comparisons of SARS-CoV-2 seroprevalence and titers between patient diagnostic subgroups, and between newly admitted (hospitalization ≤ 7 days) and hospitalized patients (hospitalization > 7 days) and correlations between serological and cytokines. RESULTS: Patients had a significantly higher SARS-CoV-2 seroprevalence (67.85 % [95% CI 62.20-73.02]) than hospital caregivers (27.08% [95% CI 21.29-33.77]), and had significantly higher global SARS-CoV-2 titers (F = 29.40, df = 2, p < 0.0001). Moreover, patients had a 2.51-fold (95% CI 1.95-3.20) higher SARS-CoV-2 exposure risk compared to hospital caregivers (Fisher's exact test, P < 0.0001). No difference was found in SARS-CoV-2 seroprevalence and titers between patient subgroups. Patients could be differentiated most accurately from hospital caregivers by their higher Spike protein titers (OR 136.54 [95% CI 43.08-481.98], P < 0.0001), lower S1 (OR 0.06 [95% CI 0.02-0.15], P < 0.0001) titers and higher IL-6 (OR 3.41 [95% CI 1.73-7.24], P < 0.0001) and TNF-α (OR 34.29 [95% CI 5.00-258.87], P < 0.0001) and lower titers of IL-8 (OR 0.13 [95% CI 0.05-0.30], P < 0.0001). Seropositive patients had significantly higher SARS-COV-2 antibody titers compared to seropositive hospital caregivers (F = 19.53, df = 2, P < 0.0001), while titers were not different in seronegative individuals. Pro-inflammatory cytokine concentrations were not associated with serological status. CONCLUSION: Our work demonstrated a very high unrecognized exposure to SARS-CoV-2 among newly admitted and hospitalized psychiatric inpatients, which is cause for concern in the context of highly robust evidence of adverse outcomes following COVID-19 in psychiatric patients. Attention should be directed toward monitoring and mitigating exposure to infectious agents within psychiatric hospitals.

RESUMO

BACKGROUND: Behçet's disease is a multisystem vasculitis of unknown origin. The prevalence of the disease varies widely and is high in the Eastern Mediterranean Basin, North Africa, Iran and Japan. Many clinical features of Behçet's disease have been described and the international study group for Behçet's disease has defined a set of diagnostic criteria. These require the presence of recurrent oral ulcers plus two of the following: recurrent genital ulcerations, typical defined eye lesions, typical defined skin lesions or a positive pathergy test (a skin hypersensitivity reaction to a non-specific physical insult; when positive, the response consists of a papule or pustule that develops after 24 to 48 hours at the site of a needle prick to the skin). Although not included in these diagnostic criteria, there are some other features commonly seen in patients with Behçet's disease: thrombophlebitis, oligo-arthritis, gastrointestinal ulcerations and neurological involvement. Neuro-Behçet is well described in Behçet's disease, with variable prevalence rates between 5.3 and 35%. This prevalence is probably affected by the type of study (retrospective or prospective) and regional and ethnic variations in disease expression. Psychiatric symptoms usually occur as incidental findings in some patients with neurological disease; they are misdiagnosed and mistreated. CASE-REPORT: The patient described here developed acute psychotic symptoms without parenchymal cerebral involvement, and negative symptoms during Behçet's disease. Two hypotheses were evoked: schizophrenia associated with Behçet's disease versus psychiatric syndrome induced by vasculitis. Such a case has not been reported in the literature. We describe the case of a 31-year-old Haitian female, admitted because of an acute psychosis. She developed hallucination, misrecognition, psychomotor hyperactivity and delusion about her million childbirths. The patient had three years history of mistreated Behçet's disease, in particular recurrent oral ulcers, iritis and cardiovascular manifestations. She also had a history of uterine tumour, rectal carcinoid tumour and recurrent pleurisies. One year ago, she presented breast lymphangitis, anxiety, unusual thought content, hostility, suspiciousness, and poor impulse control: cranial computerised tomography scan was normal. After ten days of hospitalization, she complained of oral and genital aphta and no neurological sign was found. The cerebral angiographic magnetic resonance imaging showed a thrombophlebitis of the left lateral sinus without parenchymal involvement. Haloperidol, Heparin, Colchicine, Cyclophosphamide and Prednisone were introduced. Six months after, delirium and Behçet's symptoms had disappeared with the following treatment: Risperidone, Alprazolam, Zolpidem, Colchicine, Prednisone, and Azathioprine. The patient has developed enduring negative symptoms: blunted affect, social withdrawal, difficulty in abstract thinking, lack of spontaneity and flow of conversation and poor rapport. They are still present. This patient had two acute psychotic symptoms without parenchymal pattern. After treatment, she had persistent negative symptoms and psychosocial deterioration. This evolution is commonly seen in schizophrenia. DISCUSSION: Retrospective analysis of this patient's course suggests that -psychiatric episodes were always associated with physical manifestations. However, pleurisies, lymphangitis, uterine and rectal tumours have never been described in Behçet's disease. This vasculitis occurs less frequently in the Caribbean than in Mediterranean, Middle East or Japan. It seemed that this patient had a psychotic syndrome and a chronic relapsing multisystem disorder, more complex than Behçet's disease. A prospective study would be useful to characterize psychiatric patterns of Behçet's disease and establish their relationships with physical manifestations, especially neurological involvement.

RESUMO

We have analyzed eye movement performances in schizophrenics showing primary negative or deficit symptoms (n=16) and non-deficit schizophrenics (n=55), and compared them with those of controls (n=34) in order to study the relationships between negative symptoms and eye movement abnormalities. Patients were subtyped into deficit and non-deficit subgroups using the Schedule for the Deficit Syndrome. Three oculomotor paradigms were used: smooth pursuit, a reflexive saccade paradigm and an antisaccadic task. The smooth pursuit gain was significantly decreased (and the rate of catch-up saccades increased) in schizophrenics as compared with controls, but no difference was observed between patient groups. In the reflexive saccade paradigm, no difference was found between controls and patients, except for latency in deficit patients. In the antisaccade paradigm, the number of errors and the latency of successful antisaccades were significantly increased in schizophrenics as compared with controls. The latency of successful antisaccades in both directions was significantly increased in deficit patients as compared with non-deficit patients. The latency of rightward successful antisaccades was significantly increased as compared with the latency of leftward antisaccades in deficit patients only. However, when patients were classified into negative and non-negative groups using the PANSS, no difference was found in the antisaccade paradigm. Smooth pursuit impairment does not seem to depend on the primary enduring negative symptoms.In deficit schizophrenics, the abnormalities observed in the antisaccadic task are consistent with prefrontal dysfunction, and may suggest parietal lobe dysfunction as well.

RESUMO

Coined by Sifneos in 1972, alexithymia refers to a relative narrowing in emotional functioning, an inability to find appropriate words to describe their emotions, and a poverty of fantasy life. Although initially described in the context of psychosomatic illness, alexithymic characteristics may be observed in patients with a wide range of medical and psychiatric disorders: Parkinson disease, depression, anxiety, substance abuse and eating disorders. Flattening of affect and poverty of speech, major negative symptoms, referred to chronic schizophrenia: there is a lack of outward display of emotions. Accordingly, some disturbances of alexithymia's scores would be expected in schizophrenic patients. The aims of this study were: first to establish some correlations between alexithymia and some symptoms of schizophrenia, and second to estimate the intensity of alexithymia in negative versus positive and undifferentiated schizophrenic patients. Twenty-nine patients, meeting DSM III-R criteria for schizophrenia have been studied. All of them treated by neuroleptics, were in a stable clinical status for at least one month. The patients were assessed by one trained psychiatrist (IN) using six rating scales: Beth Israel Questionnaire (BIQ) for alexithymia, Positive and Negative Syndrome Scale (PANSS), Depressive Retardation Rating Scale (DRRS), Montgomery and Asberg Depression Rating Scale (MADRS), revised Physical Anhedonia Scale (PAS), and finally, Extrapyramidal Symptom Rating Scale (ESRS). In the total sample, the mean score of BIQ was 4.79 +/- 1.68 (mean +/- SD). Significant correlations were found between alexithymia and blunted affect (r = 0.376; p < 0.05), poverty of speech (r = 0.471; p < 0.01), anxiety (r = 0.370; p < 0.05), total score of DRRS (r = 0.370; p < 0.05), and motor subscore of DRRS (r = 0.429; p < 0.05). The patients with negative symptoms of schizophrenia had significantly higher total scores in alexithymia (p < 0.05), blunted affect (p < 0.0001), poverty of speech (p < 0.0001), anxiety (p < 0.05), total score of DRRS (p = 0.01) and his motor subscore (p < 0.0001) as compared to positive and undifferentiated subtypes. In our study, alexithymia seems to be correlated with negative and depressive symptoms in negative forms of schizophrenia, regardless of medication status.

RESUMO

Coined by Sifneos in 1972, alexithymia refers to a relative narrowing in emotional functioning, an inability to find appropriate words to describe their emotions and, a poverty of fantasy life. Although initially described in the context of psychosomatic illness, alexithymic characteristics may be observed in patients with a wide range of medical and psychiatric disorders: Parkinson disease, depression, anxiety, substance abuse and eating disorders. Flattening of affect and poverty of speech, major negative symptoms, referred to chronic schizophrenia: there is a lack of outward display of emotion. Accordingly, some disturbances of alexithymia's scores would be expected in schizophrenic patients. The purpose of this study was to estimate and compare the prevalence of alexithymia in deficit and non-deficit schizophrenia. The term "deficit symptoms" may be used as Carpenter, to refer specifically to those negative symptoms that are not considered secondary. The influence of patients' symptoms has also been studied on alexithymia scores: negative and positive symptoms of schizophrenia, depression, anxiety, anhedonia and effects of neuroleptics. Twenty-five patients, meeting DSM III-R criteria for schizophrenia have been studied. All of them treated by neuroleptics, were in a stable clinical status for at least one month. The patients have been categorized into deficit (n = 12) and non-deficit (n = 13) subgroups by one trained psychiatrist (SD), using the Schedule for the Deficit Syndrome. The subjects have been assessed by the same rater (IN), blind to deficit status, using six rating scales: Beth Israel Questionnaire (BIQ) and Toronto Alexithymia Scale (TAS) for alexithymia, Positive and Negative Syndrome Scale (PANSS), Montgomery and Asberg Depression Rating Scale (MADRS), revised Physical Anhedonia Scale (PAS), and finally, Extrapyramidal Symptom Rating Scale (ESRS). Using TAS, alexithymic characteristics were more prevalent in the deficit subgroup as compared to non-deficit subgroup (83% versus 30.76%; p < 0.01). Significant correlations were observed in the non-deficit subgroup between: TAS and anxiety (r = 0.743; p < 0.01), TAS and depression (r = 0.568; p < 0.05), BIQ and blunted affect (r = 0.636; p < 0.02), BIQ and poverty of speech (r = 0.629; p < 0.02). These correlations were not significant in the deficit group of patients. Alexithymia in schizophrenic patients seems to be a trait characteristic in deficit patients, and a state related to many symptoms, such as flattening of affect, poverty of speech, depression and anxiety in nondeficit patients.
