RESUMEN

After kidney transplantation, C4d is an incomplete marker of acute antibody-mediated rejection (AMR) and C1q-binding donor-specific antibodies (DSA) have been associated with allograft survival. However, the impact on allograft survival of C1q+ DSA after clinical AMR has not been studied yet. We analysed retrospectively in clinical AMR C4d staining and C1q-binding impact on allograft survival. We compared clinical, histological and serological features of C4d- and C4d+ AMR, C1q+ and C1q- DSA AMR and analysed C4d and C1q-binding impact on allograft survival. Among 500 for-cause kidney allograft biopsies, 48 fulfilled AMR criteria. C4d+ AMR [N = 18 (37.5%)] have significantly higher number class I DSA (P = 0.02), higher microvascular score (P = 0.02) and more transplant glomerulopathy (P = 0.04). C1q+ AMR [N = 20 (44%)] presented with significantly more class I and class II DSA (P = 0.005 and 0.04) and C4d+ staining (P = 0.01). Graft losses were significantly higher in the C4d+ group (P = 0.04) but similar in C1q groups. C4d+ but not C1q+ binding was an independent risk factor for graft loss [HR = 2.65; (1.11-6.34); P = 0.028]. In our cohort of clinical AMR, C4d+ staining but not C1q+ binding is an independent risk factor for graft loss. Allograft loss and patient survival were similar in C1q+ and C1q- AMR.

RESUMEN

BACKGROUND: To assess the prevalence of early confluent/confluent white matter lesions (ec/cWMLs) in asymptomatic individuals aged ≥50 years and to identify associated clinical phenotypes. METHODS: Cross-sectional analysis of 141 asymptomatic individuals aged ≥50 years assessed at an outpatient department in France. Brain magnetic resonance imaging was rated using the Fazekas scale. Age-adjusted odds ratios (ORs) and 95% confidence intervals were estimated using logistic models to investigate factors associated with ec/cWMLs; independent risk factors were identified by multivariate analysis. RESULTS: Median age was 63 years; 53.9% were women, 32.6% had hypertension, and 76.6% had ≥1 cardiovascular risk factors. The prevalence of ec/cWMLs was 26.2%. Apart from age, independent risk factors were family history of cardiovascular event (OR = 5.55; 1.13-27.32) and hypertension (2.47; 1.05-5.81). Patients with ec/cWMLs had lower cognitive dual-task walking speed (1.15; 0.98-1.40), MMSE (1.41; 1.06-1.89), and FAB scores (5.21; 1.49-19.84). The Scheltens score was independently associated with the WML severity score. CONCLUSION: ec/cWMLs are common in asymptomatic community-dwelling individuals aged ≥50 years. They are associated with cardiovascular risk factors, impairments in global and executive cognitive function, and Scheltens score elevation.

RESUMEN

AIMS: To update the 2-year outcomes of the TOMS™ transobturator male sling for treating post-prostatectomy urinary incontinence (pRP-UI) in a group of patients previously evaluated at 1 year. METHODS: We prospectively followed 40 patients with pRP-UI before and 6, 12, and 24 months after implantation of the TOMS™ transobturator male sling. Urinary symptoms were evaluated using the following questionnaires: USP, ICIQ, UCLA-PCI (urinary bother domain), PGI-I, and daily pad use. Success was defined as patients wearing no or only one security pad. We also report on any other surgical procedures for treating persistent incontinence during the follow-up period. RESULTS: Of 40 patients included in the 1-year follow-up, seven required additional surgical treatment. In the remaining patients (n = 33), significant improvement (P < 0.001) compared to baseline was seen, and a subsequent tendency (non-significant) toward impairment was noted throughout the three postoperative follow-ups for the ICIQ (14.4 ± 4.4 [baseline], 7.6 ± 5.7 [6 months], 8.1 ± 5.6 [12 months], 8.9 ± 5.5 [24 months]), USP-stress urinary (6.7 ± 2.2, 2.8 ± 2.4, 2.8 ± 2.4, 3.2 ± 2.8), ULCA-PCI-urinary bother (10.0 ± 12.5, 66.0 ± 33.0, 64.0 ± 31.5, 62.0 ± 30.7) scores, and pad use (2.5 ± 1.2, 0.7 ± 1.1, 0.8 ± 1.2, 0.9 ± 1.2). Significant impairment in postoperative PGI-I (6.2 ± 0.9, 6.1 ± 0.9, 5.8 ± 1.1, P = 0.028) and USP-overactive bladder symptoms scores (5.4 ± 3.6 [6 months] vs. 6.6 ± 3.7 [24 months], P = 0.046) were noted. A total of 18 (54.5%), 17 (51.5%), and 15 (45.5%) patients wore no postoperative pad, respectively. CONCLUSION: Approximately half of the patients continue to wear no pad 2 years after TOMS™ transobturator male sling implantation. However, a tendency toward impaired continence, possibly associated with overactive bladder symptoms, was noted.

RESUMEN

INTRODUCTION: Erectile dysfunction (ED) affects quality of life in patients treated by radical prostatectomy (RP). The Erection Hardness Score (EHS) is a single-item scale that has demonstrated good psychometric properties for assessing erectile function (EF) in patients treated by sildenafil, but its applicability to other treatment contexts has not yet been tested. AIM: This study aims to test the validity and time and treatment responsiveness of the EHS to assess ED in men with post-RP ED treated with alprostadil injections. METHODS: This is a 1-year follow-up cohort study of 75 patients treated by RP for localized prostate cancer in a urology department setting between January 2007 and December 2008. Data were prospectively collected at 6 and 12 months post-RP. MAIN OUTCOME MEASURES: The EHS, the International Index of Erectile Function (IIEF) reference questionnaire, the Global Assessment Questionnaire (GAQ), and Numeric Pain Scale (NPS) were collected. Convergent validity (Spearman correlation coefficients with IIEF domains), known-groups validity (comparing EHS scores across ED severity groups), time and treatment responsiveness (effect size with/without treatment and over the follow-up period), and predictive ability (area under the receiver operating characteristics curve [AUC-ROC]) were analyzed for this study. RESULTS: The EHS showed good convergent validity (all Spearman coefficients significant at the P<0.05 level), adequate known-groups validity (global differentiation between IIEF-EF severity groups; P<0.001), and treatment responsiveness (effect size: +1.8 [6 months], +2.1 [12 months]), but limited time responsiveness and predictive ability of the EHS for a normal EF at 12 months follow-up when compared with the IIEF-EF domain (AUC-ROC: 0.72 vs. 0.85; P<0.01). CONCLUSION: Our findings support the overall good psychometric properties of the EHS in patients with post-RP ED treated with alprostadil injections. However, evidence for limited predictive validity and responsiveness to change over time should be considered for its use in clinical follow-up in this population.

RESUMEN

BACKGROUND: In France, the prevalence of childhood lead poisoning is becoming rare since the avoidance of lead in paints in 1949 and the gradual replacement of water pipes. Chronic lead toxicity is well known and is well correlated to blood lead concentration. AIM: Here we report a case of severe lead poisoning occurring in a young female child with a pica behavior. METHODS: A blood sample and four environmental samples were analyzed using inductively coupled plasma- mass spectrometry (ICP-MS). Lead concentration, lead isotopes and elemental ratios were compared. RESULTS: The determination of 208Pb/206Pb, 206Pb/207Pb and Cd/Pb has allowed us to identify the origin of lead poisoning. DISCUSSION-CONCLUSION: The source of contamination was eliminated and the child benefited from a psychological and medical follow up. Her outcome was positive. This case illustrated the potential interest of the use of elemental and isotopic ratios for clinical practice as the ICP-MS measurement has allowed a quick response and a rapid eviction of the contamination's source.

RESUMEN

INTRODUCTION: Intracavernous alprostadil injection (IAI) is a widely used treatment for sexual rehabilitation (SR) after radical prostatectomy (RP). It is unknown whether the continuation of IAI beyond 1 year continues to improve erectile function. AIMS: To assess evolution of sexual function in patients using IAI who are nonresponsive to phosphodiesterase type 5 inhibitors (PDE5i) between 12 (M12) and 24 (M24) months after RP. METHODS: We retrospectively studied 75 men with a nerve-sparing laparoscopic RP, who had normal preoperative erectile function, and who regularly used IAI for SR for at least 24 months. At M12, no patients had responded to PDE5i. MAIN OUTCOME MEASURES: At 12 and 24 months, sexual function was assessed with the UCLA Prostate Cancer Index (UCLA-PCI), International Index of Erectile Function (IIEF)-15, and erection hardness score (EHS) with and without IAI. We also assessed the satisfaction rate with IAI, injection-related penile pain, and satisfaction of treatment. Statistical analysis was performed by using t-tests for paired data and Spearman's rho correlation coefficients to assess the relationships between scores at M12 and M24. RESULTS: Improvement of nocturnal erection was noted (UCLA-PCI, question 25); however, no significant difference was found for IIEF-erectile function with (19.60 ± 9.80 vs. 18.07 ± 10.44) and without IAI (4.63 ± 2.93 vs. 4.92 ± 4.15), UCLA-PCI-sexual bother (37.14 ± 21.45 vs. 37.54 ± 19.67), nor the EHS score with (2.97 ± 1.30 vs. 2.57 ± 1.30) and without IAI (0.67 ± 1.11 vs. 0.76 ± 0.10). The rate of satisfaction with treatment decreased over time (66.6% vs. 46.7%, P = 0.013). Improved response to IAI at M12 was not correlated to improvement in spontaneous erections at M24. CONCLUSION: The response to IAI remained stable after 2 years of treatment, and no significant improvement of spontaneous erections during intercourse attempts was found between M12 and M24. Patients should be informed of the limited effect of IAI on natural erections after 1 year. Yiou R, Bütow Z, Parisot J, Binhas M, Lingombet O, Augustin D, de la Taille A, and Audureau E.

RESUMEN

AIMS: Sleep-disordered breathing (SDB) is highly prevalent and of adverse prognostic significance in patients with chronic heart failure (CHF). Polygraphy is used for diagnosing SDB but polygraphy resources fall short of needs. Here, our aim was to develop a score for SDB screening in patients with CHF. METHODS AND RESULTS: Consecutive patients with stable chronic CHF referred to our CHF clinic for a scheduled follow-up evaluation were included prospectively between 2000 and 2012. SDB was defined as an apnoea-hypopnoea index ≥ 5/h as assessed by routine polygraphy. A screening score was developed as a linear combination of factors independently associated with SDB by multivariate logistic regression. Calibration and discrimination were evaluated using the Hosmer-Lemeshow (HL) test and area under the receiver-operating characteristics curve (AUC), respectively. Bootstrapping was performed to assess internal validity. Of 450 included patients (mean age, 59.5 ± 13.7 years), 397 (88%) had SDB. An easy-to-use score was based on age (2 points if ≥65 years), body mass index (2 points if ≥25 kg/m(2)), New York Heart Association (NYHA) class (2 points if ≥3 or 4) and male gender (3 points). A score cut-off of 5 was 78.9% sensitive and 61.5% specific for SDB. The final model exhibited adequate calibration (pHL ≥ 0.3) and discrimination (AUC, 0.737; 95% confidence interval, 0.663; 0.810). CONCLUSION: An easy-to-use clinical score combining age, body mass index, NYHA class, and gender may help to identify those CHF patients most likely to have SDB, thereby improving the allocation of scarce polygraphy resources and early diagnosis of SDB.
