Seroprevalence of herpes simplex virus type 1 and type 2 among the migrant workers in Qatar.

BACKGROUND: Limited data exists on herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) infections in migrant populations. This study investigated HSV-1 and HSV-2 seroprevalences and associations among craft and manual workers (CMWs) in Qatar who constitute 60% of Qatar's population. METHODS: A national population-based cross-sectional seroprevalence survey was conducted on the CMW population, all men, between July 26 and September 9, 2020. 2,612 sera were tested for anti-HSV-1 IgG antibodies using HerpeSelect 1 ELISA IgG kits and for anti-HSV-2 IgG antibodies using HerpeSelect 2 ELISA IgG kits (Focus Diagnostics, USA). Univariable and multivariable logistic regression analyses were conducted to identify associations with HSV-1 and HSV-2 infections. RESULTS: Serological testing identified 2,171 sera as positive, 403 as negative, and 38 as equivocal for HSV-1 antibodies, and 300 sera as positive, 2,250 as negative, and 62 as equivocal for HSV-2 antibodies. HSV-1 and HSV-2 seroprevalences among CMWs were estimated at 84.2% (95% CI 82.8-85.6%) and 11.4% (95% CI 10.1-12.6%), respectively. HSV-1 infection was associated with nationality, educational attainment, and occupation. HSV-2 infection was associated with age, nationality, and educational attainment. CONCLUSIONS: Over 80% of CMWs are infected with HSV-1 and over 10% are infected with HSV-2. The findings highlight the need for sexual health programs to tackle sexually transmitted infections among the CMW population.

[Interpersonal psychotherapy from research to practice]. / La thérapie interpersonnelle de la recherche à la pratique.

THEORETICAL BACKGROUND: Interpersonal therapy (IPT) is a brief, structured psychotherapy initially intended to treat adult depression that was developed in the 1970s and manualized in 1984 by G. Klerman and his team. Two main theories served as a basis for its design: Bowlby's attachment theory and communication theory. Klerman theorized that tensions and problems in interpersonal relationships (i.e. disputes) cause psychological distress in vulnerable individuals that may lead to a major depressive episode. Clinical and epidemiological studies have shown that an insecure attachment style is strongly associated with lifetime depression. Severe depressive episodes have been correlated with avoidant attachment in women. THERAPY STRUCTURE AND TECHNIQUES: IPT is based on the hypothesis that recent or ongoing disturbances in interpersonal relationships either trigger or follow the onset of mood disorder. In practice, IPT assists patients in analysing their interpersonal relationship modes, correlating their relational states with their mood and in learning to use better communication. Resolving difficulties in interpersonal relationships through the use of better communication skills promotes the improvement of depressive symptoms. Klerman identified four interpersonal areas that seem to be highly correlated with depressive episodes: grief (a close and important personal relation who has died), interpersonal disputes (conflicts with significant people such as a spouse or another close family member), role transition (significant life changes such as retirement, parenthood or chronic and invalidating illness) and interpersonal deficits (patients who have limited social contacts and few interpersonal relations). Classically, IPT is planned around 12-16 weekly sessions. During the initial sessions, the therapist will explore all existing interpersonal relations and any significant dysfunctions, both recent and ongoing. Following this interview, the area the patient considers as driving the current depressive episode will be designated as the focus of therapy. Evaluation of depressive symptoms by a quantitative measure (i.e. Visual Analogue Scale) and qualitative measures (activity, pleasure, quality of life) reoccurs at each session. During the intermediate sessions, therapy uses current situations and events in the designated area that particularly affect the patient's mood. Coping, communication and decision-making skills are gradually improved through a number of techniques. These include non-directive and directive exploration, clarification, encouragement of affect, and communication analysis. The therapeutic relationship is empathetic and encouraging of all progress the patient makes. The final phases close the therapy and help the patient to plan future actions and improvements. CLINICAL TRIALS OF IPT AND DEVELOPMENTS: Several controlled clinical trials in adult populations have demonstrated the efficacy of IPT in treating Major Depressive Disorder (initial and recurrent episodes). It has been recommended as an appropriate treatment option in several guidelines. It can be provided in individual, couple or group formats. There remains an ongoing discussion of the efficacy of monthly maintenance sessions in recurrent depression. Since its conception, clinical trials have explored its use in specific populations such as adolescents and the elderly. IPT has also been the object of trial in other disorders such as post-partum depression, bipolar disorder, social phobia and eating disorders. CONCLUSION: This article reviews the basic principles and objectives of this therapeutic model. Theoretical concepts and results from research are also discussed. The approach is briefly described and the various therapeutic phases are discussed. Clinical trials have shown that IPT is effective in treating major depressive disorder in a wide variety of populations. Further trials are necessary to determine its efficacy in other psychiatric disorders.

Prevalence of hepatitis B and C viruses among migrant workers in Qatar.

Limited data exist on viral hepatitis among migrant populations. This study investigated the prevalence of current hepatitis B virus (HBV) infection and lifetime hepatitis C virus (HCV) infection among Qatar's migrant craft and manual workers (CMWs), constituting 60% of the country's population. Sera collected during a nationwide COVID-19 population-based cross-sectional survey on CMWs between July 26 and September 9, 2020, underwent testing for HBsAg and HCV antibodies. Reactive samples underwent confirmatory testing, and logistic regression analyses were employed to explore associations with HBV and HCV infections. Among 2528 specimens tested for HBV infection, 15 were reactive, with 8 subsequently confirmed positive. Three samples lacked sufficient sera for confirmatory testing but were included in the analysis through multiple imputations. Prevalence of current HBV infection was 0.4% (95% CI 0.2-0.7%). Educational attainment and occupation were significantly associated with current HBV infection. For HCV infection, out of 2607 specimens tested, 46 were reactive, and 23 were subsequently confirmed positive. Prevalence of lifetime HCV infection was 0.8% (95% CI 0.5-1.2%). Egyptians exhibited the highest prevalence at 6.5% (95% CI 3.1-13.1%), followed by Pakistanis at 3.1% (95% CI 1.1-8.0%). Nationality, geographic location, and occupation were significantly associated with lifetime HCV infection. HBV infection is relatively low among CMWs, while HCV infection falls within the intermediate range, both compared to global and regional levels.

[Management, needs and expectations of patients suffering from bipolar I disorders (The ECHO study - France)]. / Prises en charge, besoins et attentes de patients souffrant de troubles bipolaires I (Étude ECHO - France).

AIM: The ECHO study is the first French study directly asking patients with bipolar I disorders on the history and experiences of their disease, their perceptions of care, their sociofamilial relationships, and their expectations regarding what should be done by healthcare professionals and their environment. METHOD: Three hundred euthymic patients suffering from bipolar disorder I were interviewed using a semi-standardized evaluation through telephone interviews. These patients were selected according to the quota method of nationally representative INSEE 99 to be representative of the French population. RESULTS: Ninety-nine percent of patients consulted at least once for psychological signs before the correct diagnosis was established. The average age at the time of diagnosis was of 30.1 years (± 11.3). The average time between first consultation for psychological symptoms and diagnosis is about 5 years. In 92% of cases, the psychiatrist is the health professional that made the diagnosis; 74% of patients were also followed by a general practitioner. One hundred percent of participants had been hospitalized for manic episodes (criterion for inclusion in the study) and 86% were also hospitalized for depressive symptoms. The experience of hospitalization is positive (feeling of security for 84% of the sample, feelings of being helped for 81% of the sample), although these experiences are also associated with the perception of confinement (52% of the sample). At the time of the interview, 97% of these patients were followed by one or more health professionals. Only 34% of these patients were taking a mood stabilizer (lithium, anticonvulsant or atypical antipsychotic with indications in France for bipolar disorder), while 44% were taking an antidepressant and 38% were taking anxiolytics; 84% of patients had experienced side effects related to their current treatment. Acceptance of the disease is difficult and only 56% of patients personally feel they suffer from bipolar disorders. Patients believe that their mental health problems have a significant impact on their lives, including impact on their self-esteem and happiness. Relationships with family, friends but also sexual relations are affected. Even in the euthymic phase, 44% of patients have difficulties in their daily tasks. Three quarters of patients said they had already experienced rejection or discrimination related to their disease. Finally, patients gave a score of 6.4 out of 10 to assess the impact of the disorder on their quality of life. Patients request more dialogue with health professionals and a more personalized treatment, taking into account side effects. They also want more information on the treatment. They would also like to be supported, together with their families, and advised on how to cope with the disease.

SARS-CoV-2 Infection Is at Herd Immunity in the Majority Segment of the Population of Qatar.

BACKGROUND: Qatar experienced a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) epidemic that disproportionately affected the craft and manual worker (CMW) population, who comprise 60% of the total population. This study aimed to assess ever and/or current infection prevalence in this population. METHODS: A cross-sectional population-based survey was conducted during July 26 to September 09, 2020, to assess both anti-SARS-CoV-2 positivity through serological testing and current infection positivity through polymerase chain reaction (PCR) testing. Associations with antibody and PCR positivity were identified through regression analyses. RESULTS: The study included 2641 participants, 69.3% of whom were <40 years of age. Anti-SARS-CoV-2 positivity was 55.3% (95% CI, 53.3%-57.3%) and was significantly associated with nationality, geographic location, educational attainment, occupation, and previous infection diagnosis. PCR positivity was 11.3% (95% CI, 9.9%-12.8%) and was significantly associated with nationality, geographic location, occupation, contact with an infected person, and reporting 2 or more symptoms. Infection positivity (antibody and/or PCR positive) was 60.6% (95% CI, 58.6%-62.5%). The proportion of antibody-positive CMWs who had a prior SARS-CoV-2 diagnosis was 9.3% (95% CI, 7.9%-11.0%). Only seven infections were ever severe, and only 1 was ever critical-an infection severity rate of 0.5% (95% CI, 0.2%-1.0%). CONCLUSIONS: Six in every 10 CMWs in Qatar have been infected, suggestive of reaching the herd immunity threshold. Infection severity was low, with only 1 in every 200 infections progressing to be severe or critical. Only 1 in every 10 infections had been previously diagnosed, which is suggestive of mostly asymptomatic or mild infections.

[Interpersonal and social rhythm therapy (IPSRT)]. / Thérapie interpersonnelle et aménagement des rythmes sociaux (TIPARS) : du concept anglo-saxon à l'expérience française.

Bipolar disorder is common, recurrent, often severe and debiliting disorder. All types of bipolar disorder have a common determinant: depressive episode. It is justify to propose a psychotherapy which shown efficacy in depression. Howewer, perturbations in circadian rhythms have been implicated in the genesis of each episode of the illness. Biological circadian dysregulation can be encouraged by alteration of time-givers (Zeitgebers) or occurrence of time-disturbers (Zeitstörers). Addition of social rhythm therapy to interpersonal psychotherapy leads to create a new psychotherapy adaptated to bipolar disorders: InterPersonal and Social Rhythm Therapy (IPSRT). IPSRT, in combinaison with medication, has demonstrated efficacy as a treatment for bipolar disorders. IPSRT combines psychoeducation, behavioral strategy to regularize daily routines and interpersonal psychotherapy which help patients cope better with the multiple psychosocial and relationship problems associated with this chronic disorder. The main issues of this psychotherapy are: to take the history of the patient's illness and review of medication, to help patient for "grief for the lost healthy self" translated in the french version in "acceptance of a long-term medical condition", to give the sick role, to examinate the current relationships and changes proximal to the emergence of mood symptoms in the four problem areas (unresolved grief, interpersonal disputes, role transitions, role déficits), to examinate and increase daily routines and social rhythms. French version of IPSRT called TIPARS (with few differences), a time-limited psychotherapy, in 24 sessions during approximatively 6 months, is conducted in three phases. In the initial phase, the therapist takes a thorough history of previous episodes and their interpersonal context and a review of previous medication, provides psychoeducation, evaluates social rhythms, introduces the Social Rhythm Metric, identifies the patient's main interpersonal problem area, and contractualizes the therapy. In the second phase, the therapist focuses work with patient toward regulating the patient's daily routines as well as resolving the interpersonal problem areas relevant to episodes (mainly interpersonal disputes and role transitions). In the third or terminaison phase, the therapist evaluates efficacy of the therapy, enhances the patient's independent functioning and develops strategies for relapse prevention. The further maintenance phase suggests differents strategies as maintenance therapy or focused intensive interventions on specific topics.

[Schizophrenia, affective symptoms and clozapine]. / Schizophrénies, troubles thymiques et clozapine.

Clozapine has been shown to be effective in treating schizophrenic patients. In this study we compare the efficacy of clozapine in two groups of treatment resistant psychotics (among the most severe inpatients). 5 chronic schizophrenics (CS). Age 49.6 +/- 12 (paranoid, disorganized residuals). 14 "mixed" patients (MP). Age 34.6 +/- 13, between: major affective disorders (MAD) with mood incongruent psychotic features; schizo affective disorders (SAD). 19 patients (11 females -8 males) have been involved in our trial. They receive 400 up to 800 mg/day of clozapine for a minimum of 12 months and a maximum of 38 months. Treatment responders were defined on the evaluation of the following criteria: scores PANSS-CGI-MADRS (not for the first patients); number of relapses; response to socialisation (exit); quality of life. The results even if based on small sample sizes were classified as: Improvement -->reduction of all major symptoms: patient exit. CS:2/5 (40%); MP:5/14 (35%). Improvement++-->decrease of most major symptoms. CS:1/5 (20%); MP:5/14 (35%). Improvement+-->decrease of one or few major symptoms. CS:2/5 (40%); MP: 1/14 (8%). Failure-->3 from the MP subgroup (16%), 1 leucopenia, 1 worsening, 1 non responder). These finding show that affective disorders and schizoaffective patients are as likely to respond to clozapine as the schizophrenic patients: 60% of the CS and 70% of the MP were very much ( ) and much improved (++). The data also suggest that in the subtype of MP high scores of response occur with the youngest and most recently ill patients (< 30 years, < 18 months).(ABSTRACT TRUNCATED AT 250 WORDS)

[Between efficiency and toxicity: the case of a patient improved by lithium who developed iatrogenic nephropathy]. / Entre efficacité et toxicité: histoire d'un patient guéri par le lithium chez qui l'on découvre une néphropathie iatrogène.

Although almost fifteen cases have been reported since 1970, renal failure during a long term lithium therapy remains in the epidemiologic studies a rare pathology. Lithium treatment side effects can be considered in term of morphologic damages or in terms of kidney physiology impairments in filtration or concentration. For example it has long been known that lithium generates polyuria which results from an induced nephrotic diabetes insipidus (NDI). Fortunately most of these common impairments are reversible without any alarming or starting consequences. Moreover histological injures may also occur such as interstitial fibrosis, sclerotic glomeruli, tubular atrophy or dilatation ... whose evidence still raises some controversy concerning their incidence and specificity. We report here the case of a Bipolar I patient stabilized for at least fifteen years with lithium at a high level of social and professional life, in whom renal failure was found with tubular damage. This injury correlated to the lithium therapy even if always controlled at a normal rate during fifteen years, forced us to withdraw this treatment and switch to valproate. Is our goal to protect the renal function against the patient wishes totally justified since he relapsed in hypomania 63 days after the drop out? We had to choose between renal preservation and mental health.
