Abstract
COVID-19 vaccines are widely available in wealthy countries, yet many remain unvaccinated. We report on two studies (United States and France) with millions of Facebook users that tested two strategies central to vaccination outreach: health professionals addressing common concerns and motivating “ambassadors” to encourage vaccination in their social networks. We can reject very small effects of any intervention on new first doses (0.16 pp, United States; 0.021 pp, France), with similar results for second doses and boosters (United States). During the Omicron wave, messaging aimed at the unvaccinated or those tasked with encouraging others did not change vaccination decisions.

HCV cure: an appropriate moment to reduce cannabis use in people living with HIV? (ANRS CO13 HEPAVIH data). AIDS Res Ther 2022; 19:15. [PMID: 35292069 PMCID: PMC8922772 DOI: 10.1186/s12981-022-00440-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Accepted: 03/06/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Thanks to direct-acting antivirals, hepatitis C virus (HCV) infection can be cured, with similar rates in HCV-infected and HIV-HCV co-infected patients. HCV cure is likely to foster behavioral changes in psychoactive substance use, which is highly prevalent in people living with HIV (PLWH). Cannabis is one substance that is very commonly used by PLWH, sometimes for therapeutic purposes. We aimed to identify correlates of cannabis use reduction following HCV cure in HIV-HCV co-infected cannabis users and to characterize persons who reduced their use. METHODS We used data collected on HCV-cured cannabis users in a cross-sectional survey nested in the ANRS CO13 HEPAVIH cohort of HIV-HCV co-infected patients, to perform logistic regression, with post-HCV cure cannabis reduction as the outcome, and socio-behavioral characteristics as potential correlates. We also characterized the study sample by comparing post-cure substance use behaviors between those who reduced their cannabis use and those who did not. RESULTS Among 140 HIV-infected cannabis users, 50 and 5 had reduced and increased their use, respectively, while 85 had not changed their use since HCV cure. Cannabis use reduction was significantly associated with tobacco use reduction, a decrease in fatigue level, paying more attention to one's dietary habits since HCV cure, and pre-HCV cure alcohol abstinence (p = 0.063 for alcohol use reduction). CONCLUSIONS Among PLWH using cannabis, post-HCV cure cannabis reduction was associated with tobacco use reduction, improved well-being, and adoption of healthy behaviors. The management of addictive behaviors should therefore be encouraged during HCV treatment.

Abstract
Background Beyond sex, age, and various comorbidities, geographical origin and socioeconomic deprivation are associated with Coronavirus Disease (COVID-19) morbidity and mortality in the general population. We aimed to assess factors associated with severe forms of COVID-19 after a hospital emergency department visit, focusing on socioeconomic factors. Methods Patients with laboratory-confirmed COVID-19 attending the emergency department of Béclère Hospital (France) in March–April 2020 were included. Postal addresses were used to obtain two geographical deprivation indices at the neighborhood level. Factors associated with hospitalization and factors associated with adverse outcomes, i.e. mechanical ventilation or death, were studied using logistic and Cox analyses, respectively. Results Among 399 included patients, 321 were hospitalized. Neither geographical origin nor socioeconomic deprivation was associated with any of the outcomes. Being male, older, overweight or obese, diabetic, or having a neuropsychiatric disorder were independent risk factors for hospitalization. Among 296 patients hospitalized at Béclère Hospital, 91 experienced an adverse outcome. Older age, being overweight or obese, desaturation and extent of chest CT scan lesions > 25% at admission (aHR: 2.2 [95% CI: 1.3–3.5]) and higher peak CRP levels and acute kidney failure (aHR: 2.0 [1.2–3.3]) during follow-up were independently associated with adverse outcomes, whereas treatment with hydrocortisone reduced the risk of mechanical ventilation or death by half (aHR: 0.5 [0.3–0.8]). Conclusion No association between geographical origin or socioeconomic deprivation and the occurrence of a severe form of COVID-19 was observed in our population after arrival to the emergency department. Empirical corticosteroid use with hydrocortisone had a strong protective impact.

Abstract
The aim of this study is to assess the long-term effectiveness and safety of IL1Ra in Schnitzler syndrome (SchS). Between 2010 and 2012, we performed a nationwide survey among French internal medicine departments to identify SchS patients. We retrospectively analyzed the long-term efficacy and safety of IL1Ra and the outcome of patients that did not receive this treatment. Forty-two patients were included in the study, 29 of whom received IL1Ra. The mean age at disease onset was 59.9years. Disease manifestations included urticaria (100%), fever (76%), bone/joint pain (86%), bone lesions (76%), anemia (67%), and weight loss (60%). The monoclonal gammopathy was overwhelmingly IgM kappa (83%). The mean follow-up was 9.5years (range: 1.6-35). Two patients developed Waldenström's macroglobulinemia and one developed AA amyloidosis. All of the 29 patients who received IL1Ra responded dramatically. After a median follow-up of 36months (range: 2-79), the effectiveness remained unchanged. All patients remained on anti-IL-1 therapy. Twenty-four patients (83%) went into complete remission and five (17%) into partial remission. Three patients experienced grade 3-4 neutropenia. Six patients developed severe infections. No lymphoproliferative diseases occurred while on IL1Ra. When last seen, all patients without anakinra had an active disease with variable impact on their quality of life. Their median corticosteroids dosage was 6mg/d (range: 5-25). IL1Ra is effective in SchS, with a sharp corticosteroid-sparing effect. Treatment failures should lead to reconsider the diagnosis. Long-term follow-up revealed no loss of effectiveness and a favorable tolerance profile. The long-term effects on the risk of hemopathy remain unknown.

Abstract
BACKGROUND Vinblastine (VBL) is the standard treatment for systemic Langerhans cell histiocytosis (LCH), but little is known about its efficacy in central nervous system (CNS) mass lesions. METHODS A retrospective chart review was conducted. Twenty patients from the French LCH Study Group register met the inclusion criteria. In brief, they had CNS mass lesions, had been treated with VBL, and were evaluable for radiologic response. RESULTS The median age at diagnosis of LCH was 11.5 years (range: 1-50). Intravenous VBL 6 mg/m2 was given in a 6-week induction treatment, followed by a maintenance treatment. The median total duration was 12 months (range: 3-30). Eleven patients received steroids concomitantly. Fifteen patients achieved an objective response; five had a complete response (CR: 25%), ten had a partial response (PR: 50%), four had stable disease (SD: 20%) and one patient progressed (PD: 5%). Of interest, four out of the six patients who received VBL without concomitant steroids achieved an objective response. With a median follow-up of 6.8 years, the 5-year event-free and overall survival was 61% and 84%, respectively. VBL was well-tolerated and there were no patient withdrawals due to adverse events. CONCLUSION VBL, with or without steroids, could potentially be a useful therapeutic option in LCH with CNS mass lesions, especially for those with inoperable lesions or multiple lesions. Prospective clinical trials are warranted for the evaluation of VBL in this indication.

Abstract
INTRODUCTION There are insufficient data regarding the efficacy and safety of vaccination in patients with auto-immune disease (AID) and/or drug-related immune deficiency (DRID). The objective of this study was to obtain professional agreement on vaccine practices in these patients. METHODS A Delphi survey was carried out with physicians recognised for their expertise in vaccinology and/or the caring for adult patients with AID and/or DRID. For each proposed vaccination practice, the experts' opinion and level of agreement were evaluated. RESULTS The proposals relating to patients with AID specified: the absence of risk of AID relapse following vaccination; the possibility of administering live virus vaccines (LVV) to patients not receiving immunosuppressants; the pertinence of determining protective antibody titre before vaccination; the absence of need for specific monitoring following the vaccination. The proposals relating to patients with DRID specified that a 3-6 month delay is needed between the end of these treatments and the vaccination with LVV. There is no contraindication to administering LVV in patients receiving systemic corticosteroids prescribed for less than two weeks, regardless of their dose, or at a daily dose not exceeding 10mg of prednisone, if this involves prolonged treatment. Out of 14 proposals, the level of agreement between the experts was "very good" for eleven, and "good" for the remaining three. CONCLUSION Proposals for vaccine practices in patients with AID and/or DRID should aid with decision-making in daily medical practice and provide better vaccine coverage for these patients.

Abstract
Objective To study the prognosis of HIV-infected patients with virological failure after exposure to three classes of antiretroviral drugs (ARVs). Design Cohort study. Setting: French Hospital Database on HIV. Patients Patients previously exposed to at least two nucleoside reverse transcriptase inhibitors (NRTIs), two protease inhibitors and one non-NRTI, with viral load (VL) values of >5000 copies/ml after the exposure criteria were met and a new treatment initiated between 1998 and 2001 with VL >5000 copies/ml. Main outcome measures Risk of new AIDS-defining-events (ADEs) or death from first introduction of a drug never used before occurring between 1998 and 2001 defined as baseline. Results The main baseline characteristics of the 1092 patients were: previous ADE in 49% of cases, median CD4 cell count 181 μl, median VL 4.9 log10 copies/ml, median duration of ARV therapy 5.0 years and previous exposure to a median of nine ARVs. The crude progression rates were 20.1/100 patient-years among patients included in 1998, 15.1 in 1999, 11.1 in 2000 and 8.6 in 2001. After adjustment for baseline characteristics, the calendar year of inclusion was associated with the risk of clinical progression ( P<0.001). When the types of newly available drugs used at baseline or during follow-up were introduced into the model, year of inclusion was no longer associated with the risk of clinical progression ( P=0.42), while exposure to amprenavir/r, lopinavir/r, abacavir or tenofovir was associated with a lower risk. Conclusions The clinical prognosis of heavily pretreated patients experiencing virological failure improved between 1998 and 2001, mainly thanks to the use of newly available drugs with more favourable resistance profiles.

Abstract
Excisional biopsy for lymphadenopathy is sometimes necessary to confirm the diagnosis of lymphoma or metastatic disease from an unknown primary site. Lymph node excision should be preceded by less invasive approaches which may confirm a benign pathology. Collaboration with medical and hematologic specialists will allow a well-reasoned diagnostic approach with complementary studies; excisional biopsy, if necessary, will then be done under the best conditions and in the most cost-efficient manner.

Abstract
In vitro thyroid function tests are among the most frequently prescribed laboratory procedures. Serum triiodothyronine (T3) tests are seldom necessary as a first-level measurement. Our objectives were to measure the proportion of T3 measurements relative to all in vitro thyroid function tests in a large hospital network and to investigate the contributions of various interventions to change prescribers'behavior. We performed two cross-sectional surveys in 1995 and 1998 in the 50 Paris University hospitals. Questionnaires were mailed to the heads of the 30 laboratories performing thyroid function tests. One-month orders of free and total thyroxine, free and total T3 and thyrotropin were recorded; changes in T3 measurement orders between the two periods were estimated and association with interventions were expressed as odds ratios and 95% confidence intervals. Twenty-five heads of laboratory responded to both surveys. In 1995, T3 measurements constituted 21% of in vitro thyroid function test ordering, which seems to us exceedingly high. The decrease in T3 measurement ordering observed in 1998 (15% of thyroid function test ordering) was independently associated with multiple behavioral changes: educational interventions, structured test form use and year of prescription.

Abstract
OBJECTIVES To determine the distribution of orders for hormonal tests assessing thyroid function in a hospital setting. To collect the opinion of physicians specialized in endocrinology concerning free triodothyronine (FT3) assessment. METHODS Using a cross-sectional survey numbers of free thyroxine (FT4), total T4 (TT4), FT3, total T3 (TT3), and TSH tests were collected from the heads of laboratory assessing thyroid function in June 95 at the Assistance Publique-Hôpitaux de Paris (AP-HP). Cost for these tests was estimated. The physicians of the AP-HP specialized in endocrinology were asked through a questionnaire for circumstances justifying FT3 test ordering. RESULTS Twenty-eight laboratories (93%) responded: 28455 measurements (TSH: 43%, FT4: 33%, TT4: 2%, FT3: 20%, TT3: 2%) were performed and were valued at 3.4 million French Francs. Proportions of T4 (36%) and T3 (20%) tests were lower in hospitals with an inpatient department of endocrinology than in hospitals with an outpatient clinic with specialists in endocrinology (T4: 36%; T3: 27%) or with no endocrinology unit (T4: 33%, T3: 27%); proportion of TSH tests was higher in hospitals with an inpatient endocrinology unit (respectively 44%, 40%, 32%). Forty-two endocrinologists (76%) from 21 departments answered. Follow-up of treatment with amiodarone and euthyroid sick syndrome were considered the only conditions justifying FT3 test ordering. CONCLUSION Though the opinion of physicians specialized in endocrinology was not uniform regarding recommendations for TT3 or FT3 tests as a first-line measurement, the cost of these tests has been estimated at 650 thousand Francs for a month at the AP-HP.

Abstract
We analyzed the production and the roles of IL-6, IL-10, and IL-13 in B-lymphoid malignancies and in specific diseases with B-lymphocyte hyperactivity. Both IL-13 and IL-10 genes are expressed in B-cell lymphomas. However, their contribution to tumor progression is unclear. In certain lymphoproliferative disorders that develop in transplanted patients, IL-6 is produced by malignant cells and is a major factor of their proliferation. In other lymphomas, the IL-6 gene is expressed only in malignancies where differentiated malignant cells are present. In these lymphomas, IL-6 is produced by stromal cells, and the malignant cells express the IL-6 receptor. In patients with HIV infection, the level of production of IL-6, IL-10, and IL-13 is not higher than those of other conditions with immune activation. However, IL-6 contributes to increased production of IgG and IgA in vivo. In Castleman's disease, IL-6 is produced in the lymph node germinal centers, partly originating from follicular dendritic cells, which may explain some of the pathogenesis of this disease. In systemic lupus erythematosus, the critical cytokine is IL-10, which is produced in large amounts by B lymphocytes and monocytes and is responsible for autoantibody production. Taken together, these data emphasize the roles of IL-6 and IL-10, usually produced by nonlymphoid cells, on B lymphocytes, either malignant or hyperactivated.

Abstract
A sixty-year old female was referred to the Internal Medicine Department for the treatment of a diffuse high-grade non Hodgkin's lymphoma. She presented episodes of fever in context of neutropenia (neutrophils 0.35 x 10(9)/1 from 1.6 x 10(9)/1 white blood cells). Hemoglobin level was 8.2 g/dl and platelets 132 x 10(12)/1. A monoclonal IgM-Kappa protein (48 g/l) was detected in her serum. A direct antiglobulin test on the red cells proved positive with anti-C3d but not with anti-IgG antiglobulin, due to the presence of an IgM cold antibody with a serological anti-i specificity. The IgM antibody was found on the patient's neutrophils as well as in her serum. The antibody recognized all neutrophils tested in conventional serological tests whether the neutrophil phenotypes in systems NA, NB, and 5. It was demonstrated that it recognized the i antigen expressed on the neutrophils. These results suggest that a cold agglutinin anti-i might be responsible for neutropenia in some patients.

Abstract
We report a case of severe chronic bilateral uveitis in a 60-year-old white man without neurological manifestations. Spondylarthritis and isolated malabsorption suggested the diagnosis of Whipple's disease. A normal duodenal biopsy delated the diagnosis, who was secondarily demonstrated an adenopathy biopsy and macrophage study on vitrectomy sample (macrophage distended by periodic acid-Schiff positive material). With 1 year follow-up the uveitis was rapidly and completely cured by an antibiotic association (rifampicin and trimethoprim-sulfamethoxazol). The characteristics of ocular involvement in Whipple's disease and treatment of the disease are discussed.

Abstract
It has been traditionally held that developmental anomalies in language acquisition are more frequent in neonatologically at-risk subjects. There is some suggestion that proficiency in phonology is correlated with motor control development. The purpose of this paper was to compare the patterns of acquisition of the control of the acoustic-phonetic cues for voicing in the speech of premature infants and controls. The measure studied was initial stop consonant voice onset time (VOT), which is known to be the most reliable acoustic cue for the distinction between voiced and voiceless stops. The total population of the study consisted of 7 infants born at less than 37 weeks gestation and a control group of 7 infants born full-term at normal weight; 7 adults, aged 24-26 years, also participated. Each child was recorded under standard recording conditions saying words contrasting labial, dental and velar voiced and voiceless initial stops. Elicited word productions were collected monthly from infants, at different age levels, ranging from 18 to 21 months. The results show that the subjects are more advanced in the acquisition of the appropriate VOT values for the voiceless than for the voiced consonants. This difficulty may be related to the increased neuromuscular control and more complex muscle activity necessary for maintaining voicing during the closure, especially for velar stops. It is important to recognize the possibility that increased variability in preterm children may be related to some neuromuscular immaturity.

Abstract
OBJECTIVE Interleukin-10 (IL-10) is a potent stimulator of B lymphocytes in vitro. In vivo dysregulation of IL-10 gene expression was therefore analyzed in patients with rheumatoid arthritis (RA), primary Sjögren's syndrome (SS), and systemic lupus erythematosus (SLE). METHODS Spontaneous production of IL-10 by peripheral blood mononuclear cells was measured using reverse transcription polymerase chain reaction and enzyme-linked immunosorbent assay in untreated patients with either RA (n = 10), SS (n = 10), or SLE (n = 10), and in 15 normal control subjects. RESULTS IL-10 production was dramatically higher in RA, SS, and SLE patients than in controls. In each group, both B lymphocytes and monocytes, but not T lymphocytes, produced IL-10. CONCLUSION IL-10 production is increased in RA, SS, and SLE. It may play a role in B lymphocyte hyperactivity and in the development of autoimmunity.

Abstract
Expression of the IL-13 gene in malignant tissues from 26 human B-cell lymphoid malignancies was analyzed by reverse transcriptase-polymerase chain reaction (RT-PCR). A positive signal was detected in 16 cases, which included high grade B lymphomas, follicular lymphomas and B-cell chronic lymphocytic leukemias. IL-13 mRNA was also detected in the 9 malignant B cell lines and in the 6 lymphoblastoid cell lines tested, as well as in freshly isolated malignant B cells from 2 patients with a Burkitt's lymphoma. Two of 8 T-cell lymphomas and 2 of 4 T-cell lines expressed the IL-13 gene. In contrast, IL-13 gene expression was not detected in any of the 5 non-lymphoid cell lines tested. No specific binding of radiolabeled IL-13 was detected on B cell lines, suggesting an absence of IL-13 receptors on such cells. This conclusion was also supported by the inability of IL-13 or anti-IL-13 antibodies to affect the growth of malignant B cells. Taken together, these results show that both malignant and EBV-transformed B lymphocytes, either freshly isolated or maintained as cell lines, express the IL-13 gene. This raises the question of the role of B lymphocyte-derived IL-13, a B lymphocyte stimulating cytokine, on the in vivo function of normal B lymphocytes as well as on the in vivo behaviour of B lymphoid malignancies.

Abstract
Human immunodeficiency virus infection leads to a deregulated production of a number of cytokines. Some of them (IL-1, IL-6, TNF-alpha, interferon-gamma) are produced in increased amounts in vivo, whereas the production of IL-2 is decreased. This latter abnormality plays a pivotal role in the establishment of the immunodeficiency. Some cytokines (IL-1, IL-6, TNF-alpha) stimulate the in vitro replication of HIV, whereas others (mainly the interferons) inhibit it. The effect of cytokines in vivo in the spreading of HIV remains, however, largely unknown. Cytokines may also be involved in the development of many clinical manifestations associated with HIV infection. IL-1, IL-6 and TNF-alpha may play a role in tissue damages associated with opportunistic infections, in HIV-related encephalopathy and in cachexia. Cytokines, mainly IL-6, IL-10 and IL-13, may stimulate the growth of malignant cells during Kaposi sarcoma or lymphomas. Better knowledge of the role of cytokines during HIV infection should allow new therapeutic approaches based on the use of either recombinant cytokines or specific antagonists, with the aim of limiting both HIV spreading and the clinical manifestations of this infection.

Abstract
Interferon-gamma (IFN-gamma) has been shown to inhibit human immunodeficiency virus (HIV) replication in macrophages. However, the site of its effect on the HIV infectious cycle is unknown. We show here that IFN-gamma inhibits the transactivation of HIV long terminal repeat (LTR) during viral infection and that it antagonizes tat effect in HT4LacZ-1 cells. HT4LacZ-1 is an indicator CD4+ HeLa cell line for HIV infectivity, because it harbors a HIV LTR-LacZ gene susceptible to transactivation by tat. It was used in combination with a computer-assisted image analyzer to quantify: (i) the number of transactivated foci following HIV infection, (ii) their individual level of transactivation, and (iii) the fusion potency of infected cells. IFN-gamma induced a 75% decrease of the number of transactivated foci following infection of HT4LacZ-1 cells by HIV. The remaining 25% foci still susceptible to transactivation were transactivated at a lower level than in control cultures, and the fusion potency of infected cells was strongly decreased. IFN-gamma acted after HIV entry into the cell and independently of reverse transcription. IFN-gamma antagonized tat-induced LTR transactivation: it inhibited transactivation of HT4LacZ-1 cells when tat was provided either from a SV40-based expression vector of tat or by polyethylene glycol-induced cell fusion with HeLa-tat-III cells. These results suggest that IFN-gamma affects the expression or the activity of cellular factors interacting with tat and that the high level of IFN-gamma production associated with HIV infection plays a role in the establishment of HIV latency.

Abstract
The clinical and pathological features of a patient with giant cell arteritis of the uterus and ovaries are described. A 61 year old woman had fever and weight loss over a period of eight months. A hysterectomy with bilateral salpingo-oophorectomy was performed for a large cystic ovarian mass. Histological examination showed a benign ovarian cyst and unexpected giant cell arteritis affecting numerous small to medium sized arteries in the ovaries and myometrium. The diagnosis of temporal arteritis was confirmed by a random temporal artery biopsy, despite the absence of symptoms of temporal arteritis. This observation is compared with previously reported cases and the relation between granulomatous arteritis of the genital tract and temporal arteritis is discussed. The main differential diagnosis in this localisation was represented by Wegener's granulomatosis and periarteritis nodosa.
