Abstract
Objective Data about efficacy and safety of the latest COVID-19 treatments as nirmatrelvir/ritonavir (n/r) or Sotrovimab is scarce in solid organ transplant recipients in the Omicron era. This study aims at describing the outcome of kidney transplant recipients (KTRs) presenting Omicron infection according to their management: n/r, sotrovimab or no specific treatment. Patients and methods We conducted a monocentric, retrospective observational study, including KTRs diagnosed Omicron infection between January and May 1st 2022 and compared their outcome (primary outcome defined as hospital admission for COVID-19 within a month after symptoms onset) according to early COVID-19 management. Results Forty-five patients were included: 22 treated (12 n/r, 10 sotrovimab) and 23 with no specific treatment. The groups were statistically comparable. Two patients were admitted for COVID-19: one in each group, resulting in a non-different probability of the primary outcome at on month (p=0.9). Three patients presented tacrolimus overdose including two with acute kidney injury. Conclusions There was no difference in outcome according to early therapeutic management: n/r, sotrovimab or no specific treatment. Our study both underlines a decreased severity of Omicron COVID-19 in KTRs (probably related to vaccinal immunity and decreased virulence of Omicron) and a potential severe adverse effects with n/r.

Abstract
BACKGROUND Renal biopsy is the cornerstone of systemic lupus erythematosus (SLE) nephritis and antiphospholipid syndrome (APS) nephropathy management. However, transcutaneous renal biopsy (TCRB) is hampered by the antithrombotic treatment frequently prescribed for those diseases. Transjugular renal biopsy (TJRB) offers an attractive alternative for patients at increased risk of bleeding. The primary objective of the study was to describe the safety profile and diagnostic performance of TJRB in SLE and APS patients. METHODS All SLE and/or APS patients who underwent a renal biopsy in our department (between January 2004 and October 2016) were retrospectively reviewed. Major complications were death, haemostasis nephrectomy, renal artery embolization, red blood cell transfusion, sepsis and vascular thrombosis; macroscopic haematuria, symptomatic perirenal/retroperitoneal bleeding and renal arteriovenous fistula without artery embolization were considered as minor complications. RESULTS Two hundred and fifty-six TJRBs-119 without antithrombotics (untreated), 69 under aspirin and 68 on anticoagulants and 54 TCRBs without antithrombotics-were analysed. Their major and minor complication rates, respectively, did not differ significantly for the four groups: 0 and 8% for untreated TJRBs, 1 and 6% for aspirin-treated, 6 and 10% for anticoagulant-treated and 2 and 2% for TCRBs. The number of glomeruli sampled and the biopsy contribution to establishing a histological diagnosis was similar for the four groups. CONCLUSIONS TJRBs obtained from SLE and APS patients taking antithrombotics had diagnostic yields and safety profiles similar to those of untreated TCRBs. Thus, TJRB should be considered for SLE and APS patients at risk of bleeding.

Abstract
BACKGROUND AND OBJECTIVES Metabolic acidosis is a frequent manifestation of sickle cell disease but the mechanisms and determinants of this disorder are unknown. Our aim was to characterize urinary acidification capacity in adults with sickle cell disease and to identify potential factors associated with decreased capacity to acidify urine. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Among 25 adults with sickle cell disease and an eGFR of ≥60 ml/min per 1.73 m2 from a single center in France, we performed an acute acidification test after simultaneous administration of furosemide and fludrocortisone. A normal response was defined as a decrease in urinary pH <5.3 and an increase in urinary ammonium excretion ≥33 µEq/min at one or more of the six time points after furosemide and fludrocortisone administration. RESULTS Of the participants (median [interquartile range] age of 36 [24-43] years old, 17 women), 12 had a normal and 13 had an abnormal response to the test. Among these 13 participants, nine had normal baseline plasma bicarbonate concentration. Plasma aldosterone was within the normal range for all 13 participants with an abnormal response, making the diagnosis of type 4 tubular acidosis unlikely. The participants with an abnormal response to the test were significantly older, more frequently treated with oral bicarbonate, had a higher plasma uric acid concentration, higher hemolysis activity, lower eGFR, lower baseline plasma bicarbonate concentration, higher urine pH, lower urine ammonium ion excretion, and lower fasting urine osmolality than those with a normal response. Considering both groups, the maximum urinary ammonium ion excretion was positively correlated with fasting urine osmolality (r 2=0.34, P=0.002), suggesting that participants with sickle cell disease and lower urine concentration capacity have lower urine acidification capacity. CONCLUSIONS Among adults with sickle cell disease, impaired urinary acidification capacity attributable to distal tubular dysfunction is common and associated with the severity of hyposthenuria.

Abstract
Sickle cell disease (SCD), the most common hemoglobinopathy, is an increasing cause of chronic kidney disease. In the last decade, we have witnessed a better understanding in the characterization of clinical manifestations and pathogenesis of sickle cell nephropathy. The spectrum of renal diseases during SCD includes various renal manifestations such as impairment of urinary concentrating ability, defect in urine acidification, renal papillary necrosis and proteinuria related to glomerular injury leading to progressive end-stage renal disease. Endothelial dysfunction related to chronic hemolysis and the relative renal hypoxia caused by vaso-occlusive sickle red blood cells are probably two key factors for SCN development. Optimal therapeutic management (including the use of blockers of the renin-angiotensin system) of patients with proteinuria remains to be determined. Renal replacement therapy with dialysis is required in SCD patients with end-stage renal disease but these patients should probably undergo kidney transplantation that requires careful management.

Abstract
UNLABELLED This paper reports the first data of a study on heart rate variations of 13 5-mo-old infants seated in special chairs. Their electrocardiograms and behaviour were continuously recorded during sessions that were set up with their mother and a mother-child dyad that they met for the first time when the first session was organized. The protocol comprised two interaction phases between the infants and their mothers and two with one another. The same pairs of mother-child dyads were studied a second time 1 wk later. During the first session, the infants' heart rate variability increased significantly from the mother-infant interaction phases to the infant-infant interaction phases. During the second session, the variability was higher during the mother-infant phases than in the corresponding phases of the first session. This could be linked to changes in the mothers' behaviour and the infants' idea and excitement of meeting the child from the first session again. However, the variability was significantly lower during the infant-infant phases than during the mother-infant phases and the corresponding infant-infant phases of the first session. This corresponds to the development of affiliative behaviours in the infants. CONCLUSION When two 5-mo-old infants were seated by their mothers in special chairs, significant differences were observed in their heart rate variability when they became familiar with each other, whether they were interacting with their mothers or with one another.

Abstract
A high-performance liquid chromatographic method with UV detection has been developed for the analysis of clozapine and its active N-desmethylated metabolite (N-desmethylclozapine = DMC) in human plasma. A liquid/liquid procedure was used to extract clozapine and DMC from human plasma. The analysis was performed on a C8 Nucleosil column and the mobile phase comprised acetonitrile-water-Pic B5 diethylamine (63:37:25:0.04, v/v/v/v). The detection wavelength was 245 nm. The intra-assay and inter-assay precision was satisfactory within the concentration range 10-900 ng ml-1. The lower detection limit for clozapine and for DMC was 5 ng ml-1. The recovery and reproducibility values of this method were better or similar to those found by other authors. This method, which is simple, selective and avoids an evaporation step, can be used routinely for therapeutic drug monitoring.

Abstract
INTRODUCTION Rapid cycling among bipolar disorders was characterized in 1974 by Dunner and Fieve by at least 4 episodes per year, lithium resistance, female predominance. The idea of using thyroid hormones is based on frequent coexisting thyroid dysfunction. Thyroid hormones where first used in the forties, and more recently (table I) in open label and blind trials (Stancer et Persad, 1982; Bauer et Whybrow, 1990). OBJECTIVE Open label study of levothyroxine in rapid cycling bipolar disorder. MATERIAL AND METHODS Six subjects (4 females and 2 males, mean age 45.5 years at onset of bipolar disorder) meeting DMS III-R criteria for rapid cycling bipolar disorder were consecutively included in an open label study of levothyroxine. Subject characteristics are presented in table II. RESULTS After almost two years follow-up results appear positive in 67% of cases (2 complete remissions, 2 partial remissions and 2 failures). CONCLUSION Our cases, with data reported in the literature, support the potential efficacy of levothyroxine for treatment of rapid cycling bipolar disorder patients. We suggest a protocol for the good application of this potential new treatment (table III).

Abstract
Stapedius reflex can provide useful prognostic information in FPs when the middle ear is normal. Its preservation may have a favorable significance in partial FP and Bell's palsy. Its loss, even though less reliable, can also have some value as an indicator for a poor prognosis in patients with total and herpes zoster FPs. Most importantly, our findings have shown that the SR alone is not sufficient to be of prognostic value, but is useful if combined with other clinical parameters and electrical responses.

Abstract
Electrical prognosis was evaluated in 79 patients with facial paralysis, of spontaneous (n = 43) or post-traumatic origin (n = 36). Three electrophysiological tests were employed jointly: detection, stimulation and stimulodetection. The patients were reviewed at least 1 year later, in order to appreciate the agreement between the electrical prognosis and the clinical outcome (satisfactory or not). Those patients with a favourable prognosis on electrical testing had in the majority of cases a satisfactory outcome. The accuracy of the prognosis was also better in cases of early examination (within 15 days) and partial paralysis.
