Allocation aux adultes handicapés : pathologies et recours aux soins des bénéficiaires en 2017.

OBJECTIVE: We described the pathologies and health care utilization of beneficiaries of the general health insurance scheme via the Allocation Adulte Handicapé (AAH - Adult Disability Allowance) compared to the general population. METHOD: Mapping of pathologies and expenditures allowed the identification of 58 pathologies and chronic treatments in the SNDS, thanks to ICD-10 codes for long-term conditions or hospitalizations, specific drugs or medical procedures, among all beneficiaries of the general health insurance scheme aged 20 to 64 years with reimbursed care (>1€) in 2017. The prevalence and annual rates of care utilization among all beneficiaries of the general scheme via AAH (“AAH” group) and in the rest of the population (“non-AAH”) were standardized and described. RESULTS: Among the 793,934 (2.51% of the population) “AAH” persons, all the pathologies studied were more frequent than among the “non-AAH”, with 44% having psychiatric pathologies (compared with 3.2%), and 14% a neurological pathology (compared with 1%). AAH beneficiaries were more likely to use hospital care (63% versus 40%), but less likely to use specialist care (63% versus 68%) and dental care (37% versus 45%). CONCLUSION: The beneficiaries of the general scheme via the AAH had mainly psychiatric and neurological pathologies, but other pathologies were also much more frequent than in the general population. The lower use of dental and specialist care was probably related to a lack of access to care, potentially caused by the absence of 100% coverage of care.

Meta-analysis of chemotherapy in head and neck cancer (MACH-NC): An update on 107 randomized trials and 19,805 patients, on behalf of MACH-NC Group.

BACKGROUND AND PURPOSE: The Meta-Analysis of Chemotherapy in squamous cell Head and Neck Cancer (MACH-NC) demonstrated that concomitant chemotherapy (CT) improved overall survival (OS) in patients without distant metastasis. We report the updated results. MATERIALS AND METHODS: Published or unpublished randomized trials including patients with non-metastatic carcinoma randomized between 1965 and 2016 and comparing curative loco-regional treatment (LRT) to LRT + CT or adding another timing of CT to LRT + CT (main question), or comparing induction CT + radiotherapy to radiotherapy + concomitant (or alternating) CT (secondary question) were eligible. Individual patient data were collected and combined using a fixed-effect model. OS was the main endpoint. RESULTS: For the main question, 101 trials (18951 patients, median follow-up of 6.5 years) were analyzed. For both questions, there were 16 new (2767 patients) and 11 updated trials. Around 90% of the patients had stage III or IV disease. Interaction between treatment effect on OS and the timing of CT was significant (p < 0.0001), the benefit being limited to concomitant CT (HR: 0.83, 95%CI [0.79; 0.86]; 5(10)-year absolute benefit of 6.5% (3.6%)). Efficacy decreased as patients age increased (p_trend = 0.03). OS was not increased by the addition of induction (HR = 0.96 [0.90; 1.01]) or adjuvant CT (1.02 [0.92; 1.13]). Efficacy of induction CT decreased with poorer performance status (p_trend = 0.03). For the secondary question, eight trials (1214 patients) confirmed the superiority of concomitant CT on OS (HR = 0.84 [0.74; 0.95], p = 0.005). CONCLUSION: The update of MACH-NC confirms the benefit and superiority of the addition of concomitant CT for non-metastatic head and neck cancer.

Risk Factors for Unnecessary Antibiotic Therapy: A Major Role for Clinical Management.

BACKGROUND: Assessment of antimicrobial use places an emphasis on therapeutic aspects of infected patients. Our aim was to determine the risk factors for unnecessary antibiotic therapy (UAT). METHODS: This was a prospective, multicenter study evaluating all curative antibiotic therapies prescribed over 2 consecutive days through the same electronic medical records. Each item that could participate in these prescriptions was collected from the computerized file (reason for hospitalization, comorbid conditions, suspected or definitive diagnosis of infection, microbial analyses). UAT was defined as the recognition of noninfectious sydromes (NIS), nonbacterial infections, use of redundant antimicrobials, and continuation of empirical broad-spectrum antimicrobials. RESULTS: Four hundred fifty-three antibiotic therapies were analyzed at 17 institutions. An infectious disease was the reason for hospitalization in 201 cases (44%). An unspecified diagnosis of infection was observed in 104 cases (23%). Microbial samples were taken in 296 cases (65%), allowing isolation of a pathogen in 156 cases (53%). Unspecified diagnosis was associated with the absence of a microbial sample compared to patients with a diagnosis: (56/104 [54%] vs 240/349 [69%]; P = .005). A total of 158 NIS were observed (35%). UAT was observed in 169 cases (37%), due to NIS in 106 cases. In multivariate analysis, the modifiable risk factors for UAT were unspecified diagnosis (adjusted odds ratio [AOR], 1.83; 95% confidence interval [CI], 1.04-3.20) and absence of a blood culture (AOR, 5.26; 95% CI, 2.56-10.00). CONCLUSIONS: UAT is associated with an unspecified diagnosis and the absence of microbial testing. Antimicrobial stewardship programs should focus on diagnostic difficulties and microbial testing, the latter facilitating antibiotic reassessment and therapeutic interruption.

Cost-effectiveness of left ventricular assist devices for patients with end-stage heart failure: analysis of the French hospital discharge database.

AIMS: Although left ventricular assist devices (LVADs) are currently approved for coverage and reimbursement in France, no French cost-effectiveness (CE) data are available to support this decision. This study aimed at estimating the CE of LVAD compared with medical management in the French health system. METHODS AND RESULTS: Individual patient data from the 'French hospital discharge database' (Medicalization of information systems program) were analysed using Kaplan-Meier method. Outcomes were time to death, time to heart transplantation (HTx), and time to death after HTx. A micro-costing method was used to calculate the monthly costs extracted from the Program for the Medicalization of Information Systems. A multistate Markov monthly cycle model was developed to assess CE. The analysis over a lifetime horizon was performed from the perspective of the French healthcare payer; discount rates were 4%. Probabilistic and deterministic sensitivity analyses were performed. Outcomes were quality-adjusted life years (QALYs) and incremental CE ratio (ICER). Mean QALY for an LVAD patient was 1.5 at a lifetime cost of €190 739, delivering a probabilistic ICER of €125 580/QALY [95% confidence interval: 105 587 to 150 314]. The sensitivity analysis showed that the ICER was mainly sensitive to two factors: (i) the high acquisition cost of the device and (ii) the device performance in terms of patient survival. CONCLUSIONS: Our economic evaluation showed that the use of LVAD in patients with end-stage heart failure yields greater benefit in terms of survival than medical management at an extra lifetime cost exceeding the €100 000/QALY. Technological advances and device costs reduction shall hence lead to an improvement in overall CE.

18F-FDG PET/CT as a central tool in the shift from chronic Q fever to Coxiella burnetii persistent focalized infection: A consecutive case series.

Because Q fever is mostly diagnosed serologically, localizing a persistent focus of Coxiella burnetii infection can be challenging. F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) could be an interesting tool in this context.We performed a retrospective study on patients diagnosed with C burnetii infection, who had undergone F-FDG PET/CT between 2009 and 2015. When positive F-FDG PET/CT results were obtained, we tried to determine if it changed the previous diagnosis by discovering or confirming a suspected focus of C burnetii infection.One hundred sixty-seven patients benefited from F-FDG PET/CT. The most frequent clinical subgroup before F-FDG PET/CT was patients with no identified focus of infection, despite high IgG1 serological titers (34%). For 59% (n = 99) of patients, a hypermetabolic focus was identified. For 62 patients (62.6%), the positive F-FDG PET/CT allowed the diagnosis to be changed. For 24 of them, (38.7%), a previously unsuspected focus of infection was discovered. Forty-two (42%) positive patients had more than 1 hypermetabolic focus. We observed 21 valvular foci, 34 vascular foci, and a high proportion of osteoarticular localizations (n = 21). We also observed lymphadenitis (n = 27), bone marrow hypermetabolism (n = 11), and 9 pulmonary localizations.We confirmed thatF-FDG PET/CT is a central tool in the diagnosis of C burnetii focalized persistent infection. We proposed new diagnostic scores for 2 main clinical entities identified using F-FDG PET/CT: osteoarticular persistent infections and lymphadenitis.

Nocardia veterana: disseminated infection with urinary tract infection

Nocardia spp. are a group of aerobic actinomycetes widely distributed in soil, and associated with severe opportunistic infections, essentially pulmonary infections. We report the first case of disseminated infection associated with urinary tract infection caused by Nocardia veterana. The diagnosis was difficult; despite the presence of pulmonary nodules, the lung biopsies remained negative while only one aerobic blood culture and the urine culture were positive for N. veterana, identified after a 16S rDNA gene sequence analysis. Few cases of clinical importance due to N. veterana have been published since its characterization. The bacteriological diagnosis of nocardiosis can be difficult to establish because of the delayed growth and the specific techniques that are required. This case illustrates the necessity of performing specific investigations in immunocompromised patients who present with infectious disease because the severity of this infection requires early diagnosis and quick initiation of appropriate antibiotic therapy.

[Respiratory manifestations of giant cell arteritis: 8 cases and review of the literature]. / Atteinte respiratoire de la maladie de Horton: 8 observations et revue de la littérature.

BACKGROUND: Pleural and pulmonary manifestations of giant cell arteritis are rare and not well known. They can be associated to more typical signs of the disease and to an inflammatory biological syndrome which are comprised in the multisystemic manifestations of the disease. They can be inaugural, leading to a late management if unrecognized. METHODS: Retrospective and descriptive study of 8 cases over a 10 year period was conducted. Five females and three males with a 67-year-old average age were included according to the American College of Rheumatology criteria. They illustrated the clinical and/or radiological respiratory manifestations of the disease. RESULTS: Pulmonary manifestation was inaugural in six cases over eight. The time to diagnosis range was 15-60 days. Cough was the most frequent symptom (five cases over eight). Dyspnea with orthopnea was described in one case. Pleural and parenchymal radiological manifestations had no specific characteristics: pleurisy, pleural thickening, nodules of variable size, reticular lesions. Temporal artery biopsy was positive in five cases, atypical in one case and negative in two cases. Bronchial and transbronchial biopsies (in two and one cases respectively) did not find any specific lesion. Clinical and radiological signs disappeared quickly after the introduction of glucocorticoid therapy. CONCLUSION: The knowledge of these different respiratory manifestations during giant cell arteritis (persistent cough, nodules, pleural effusion) is useful for the clinician. It helps him in prescribing non invasive investigations or even a presumptive glucocorticoid therapy, in an often old and weakened patient.

Pericardial effusion as the only manifestation of infection with Francisella tularensis: a case report.

INTRODUCTION: Francisella tularensis, a facultative intracellular Gram-negative bacterium, has rarely been reported as an agent of pericarditis, generally described as a complication of tularemia sepsis. F. tularensis is a fastidious organism that grows poorly on standard culture media and diagnosis is usually based on serological tests. However, cross-reactions may occur. Western blotting allows the correct diagnosis. CASE PRESENTATION: A non-smoking 53-year-old woman was admitted to hospital with a large posterior pericardial effusion. Serological tests showed a seroconversion in antibody titers to F. tularensis (IgG titer = 400) and Legionella pneumophila (IgG titer = 512). F. tularensis was identified by Western immunoblotting following cross-adsorption. The patient reported close contact with rabbits 2 weeks prior to the beginning of symptoms of pericarditis. CONCLUSION: We report a rare case of pericardial effusion as the only manifestation of infection by F. tularensis. The etiological diagnosis is based on serology. Western blotting and cross-adsorption allow differential diagnosis.

From acute Q fever to endocarditis: serological follow-up strategy.

The serological evolution from acute Q fever to endocarditis is reported for 22 patients, with a median lag time of 3 months. From this data, we propose a follow-up strategy of serological testing at the third and sixth months after acute Q fever to obtain an early diagnosis of chronic infection.

Amyloid arthropathy and Waldenström macroglobulinemia.

Amyloid arthropathy occurs chiefly as a manifestation of beta(2) microglobulin amyloidosis in patients receiving chronic hemodialysis. AL amyloidosis complicating multiple myeloma is a less common cause. Amyloid arthropathy is exceedingly rare in patients with Waldenström macroglobulinemia. We report a case characterized by lymphoplasmocytoid malignancy with monoclonal IgM production and amyloid arthropathy manifesting as bilateral symmetric polyarthritis. A synovial membrane biopsy established the diagnosis. Chemotherapy was effective in alleviating the joint manifestations. Joint symptoms in patients with monoclonal gammopathies, including those characterized by IgM secretion, should suggest amyloid arthropathy. Treatment of the blood disease may improve the joint symptoms.

RS3PE revealing recurrent non-Hodgkin's lymphoma.

A patient meeting published criteria for remitting seronegative symmetrical synovitis with pitting edema (RS3PE) was found to have a synchronous recurrence of non-Hodgkin's malignant lymphoma. Reported cases of RS3PE associated with hematological malignancies and other forms of cancer are reviewed.
