T-Cell Receptor Excision Circles in HIV-Exposed, Uninfected Newborns Measured During a National Newborn Screening Program for Severe Combined Immunodeficiency.

International audienceSevere combined immunodeficiency screening by measuring T-receptor excision circles at birth allows evaluation of the impact of various maternal conditions on newborn immunity. The slight decrease observed in a French cohort of newborns to HIV-infected mothers can be explained by the confounding factors of prematurity and African descent

Newborn Screening for Severe Combined Immunodeficiency: Analytic and Clinical Performance of the T Cell Receptor Excision Circle Assay in France (DEPISTREC Study)

International audienceSevere combined immunodeficiency (SCID) is characterized by a major T cell deficiency. Infants with SCID are asymptomatic at birth but die from infections in the first year of life if not treated. Survival rates are better for early treatment. SCID therefore meets criteria for newborn screening (NBS). T cell receptor excision circle (TREC) quantification is a reliable marker of T cell deficiency and can be performed using Guthrie cards. The DEPISTREC project was designed to study the feasibility, clinical utility, and cost-effectiveness of generalized SCID screening in France. About 200,000 babies from all over the country were screened at birth with a commercial kit. We determined assay performance and proposed a cutoff for classification of results. Our findings suggest that, given clearly established validation rules and decision-making procedures, the TREC assay is a suitably specific and sensitive method for high-throughput SCID screening.

Hospital production cost of transcranial direct current stimulation (tDCS) in the treatment of depression

International audienceOBJECTIVES:Due to its ease of use, tolerance, and cost of acquisition, transcranial direct current stimulation (tDCS) could constitute a credible therapeutic option for non-resistant depression in primary care, when combined with drug management. This indication has yet to receive official recognition in France. The objective of this study is to evaluate the production cost of tDCS for the treatment of depression in hospitals, under realistic conditions.METHODS:The methodology adopted is based on cost accounting and was validated by a multidisciplinary working group. It includes equipment, staff, and structural costs to obtain the most realistic estimate possible. We first estimated the cost of producing a tDCS session, based on our annual activity objective, and then estimated the cost of a 15-session treatment program. This was followed up with a sensitivity analysis applying appropriate parameters.RESULTS:The hospital production cost of a tDCS depression treatment program for a single patient was estimated at €1555.60 euros: €99 in equipment costs, €1076.95 in staff costs, and €379.65 in structural costs.CONCLUSION:This cost analysis should make it possible to draw up pricing proposals in compliance with regulations and health policy choices and to develop health-economic studies. This would ultimately lead to official recognition of tDCS treatment for depression in France and pave the way for studying various scenarios of coverage by the French national health insurance system

Cost-Utility Analysis of Curative and Maintenance Repetitive Transcranial Magnetic Stimulation (rTMS) for Treatment-Resistant Unipolar Depression: A Randomized Controlled Trial Protocol

International audienceBACKGROUND: Depression is a debilitating and costly disease for our society, especially in the case of treatment-resistant depression (TRD). Repetitive transcranial magnetic stimulation (rTMS) is an effective adjuvant therapy in treatment-resistant unipolar and non-psychotic depression. It can be applied according to two therapeutic strategies after an initial rTMS cure: a further rTMS cure can be performed at the first sign of relapse or recurrence, or systematic maintenance rTMS (M-rTMS) can be proposed. TMS adjuvant to treatment as usual (TAU) could improve long-term prognosis. However, no controlled study has yet compared the cost-effectiveness of these two additional rTMS therapeutic strategies versus TAU alone. METHODS/DESIGN: This paper focuses on the design of a health-economic, prospective, randomized, double-blind, multicenter study with three parallel arms carried out in France. This study assesses the cost-effectiveness of the adjunctive and maintenance low frequency rTMS on the right dorsolateral prefrontal cortex versus TAU alone. A total of 318 patients suffering from a current TRD will be enrolled. The primary endpoint is to investigate the incremental cost-effectiveness ratio (ICER) (ratio costs / quality-adjusted life-years [QALY] measured by the Euroqol Five Dimension Questionnaire) over 12\,months in a population of patients assigned to one of three arms: systematic M-rTMS for responders (arm A); additional new rTMS cure in case of mood deterioration among responders (arm B); and a placebo arm (arm C) in which responders are allocated in two subgroups: sham systematic M-rTMS and supplementary rTMS course in case of mood deterioration. ICER and QALYs will be compared between arm A or B versus arm C. The secondary endpoints in each three arms will be: ICER at 24\,months; the cost-utility ratio analysis at 12 and 24\,months; 5-year budget impact analysis; and prognosis factors of rTMS. The following criteria will be compared between arm A or B and arm C: rates of responders; remission and disease-free survival; clinical evolution; tolerance; observance; treatment modifications; hospitalization; suicide attempts; work stoppage; marital / professional statues; and quality of life at 12 and 24\,months. DISCUSSION: The purpose of our study is to check the cost-effectiveness of rTMS and we will discuss its economic impact over time. In the case of significant decrease in the depression costs and expenditures associated with a good long-term prognosis (sustained response and remission) and tolerance, rTMS could be considered as an efficient treatment within the armamentarium for resistant unipolar depression.

Efficacy of Spironolactone Compared with Doxycycline in Moderate Acne in Adult Females: Results of the Multicentre, Controlled, Randomized, Double-blind Prospective and Parallel Female Acne Spironolactone vs doxyCycline Efficacy (FASCE) Study

Acne in adult females is triggered mainly by hormones. Doxycycline is a reference treatment in acne. Spironolactone targets the androgen receptor of sebaceous glands and is prescribed off-label for female adult acne. This multicentre, controlled, randomized, double-blind prospective and parallel study assessed the efficacy of spironolactone compared with doxycycline in adult female acne. A total of 133 women with moderate acne were randomized to receive treatment with: (i) doxycycline and benzoyl peroxide for 3 months followed by a 3-month treatment with its placebo and benzoyl peroxide, or (ii) spironolactone and benzoyl peroxide for 6 months. Successfully treated patients continued with benzoyl peroxide or spironolactone alone for a further 6 months. Primary endpoints were treatment success at month 4 and month 6 with the AFAST score. At all visits, the ECLA score, lesion counts, local and systemic safety and quality of life were assessed. Spironolactone performed better at month 4 and showed a statistically significant better treatment success after 6 months than doxycycline (p = 0.007). Spironolactone was 1.37-times and 2.87-times more successful compared with doxycycline at respective time-points. AFAST and ECLA scores, as well as lesion counts always improved more with spironolactone. Patients’ quality of life was better with spironolactone at month 4 and month 6. Spironolactone was very well tolerated. This is the first study to show that, in female adults with moderate acne, treatment with spironolactone is significantly more successful than doxycycline and very well tolerated

FASCE, the benefit of spironolactone for treating acne in women: study protocol for a randomized double-blind trial

International audienceBackground: Acne vulgaris has increased in women over the past 10 years; it currently affects 20-30% of women. The physiopathology of adult female acne is distinguished from that of teenagers essentially by two factors: hormonal and inflammatory. On a therapeutic plan, the four types of systemic treatment approved for female acne include cyclines (leading to bacterial resistance); zinc salts (less effective than cyclines); and antiandrogens (risks of phlebitis). The last alternative is represented by isotretinoin, but its use in women of childbearing potential is discouraged because of the teratogen risks. In this context, spironolactone could represent an interesting alternative. It blocks the 5-alpha-reductase receptors at the sebaceous gland and inhibits luteinizing hormone (LH) production at the pituitary level. It has no isotretinoin constraints and does not lead to bacterial resistance. Currently, very few studies have been performed in a limited number of patients: the studies showed that at low doses (lower than 200 mg/day), spironolactone can be effective against acne. In that context, it is clearly of interest to perform the first double-blind randomized study of spironolactone versus cyclines, which remains the moderate acne reference treatment, and to demonstrate the superiority of spironolactone's efficacy in order to establish it as an alternative to cyclines. Methods: Two hundred female patients will be included. They must have acne vulgaris with at least 10 inflammatory lesions and no more than 3 nodules. After randomization, the patients will be treated by spironolactone or doxycycline for 3 months and after placebo. The study will be blind for the first 6 months and open for the last 6 months. Discussion: The treatment frequently used in female acne is systemic antibiotics with many courses, as it is a chronic inflammatory disease. In the context of the recent World Health Organisation (WHO) revelation about the serious, worldwide threat to public health of antibiotic resistance, this trial could give the physician another alternative in the treatment of adult female acne instead of using isotretinoin, which is more complex to manage.
