A 29-year-old man with a history of aplastic anemia, who was being treated with cyclosporine, presented to the emergency department with a 4-day history of fever, cough, and difficulty breathing at rest. One day before the onset of symptoms, a pruritic rash had developed on his face, trunk, and limbs. On physical examination, he had a diffuse rash at different stages of development, including papules, vesicles (Bläschen), pustules, and crusted vesicles. What is the diagnosis? Eosinophilic granulomatosis with polyangiitis Disseminated varicella infection Disseminated intravascular coagulation Drug-induced hypersensitivity syndrome Immune thrombocytopenia purpura A chest radiograph showed multiple nodules coalescing to form nodular consolidation and infiltrates in both lungs. A clinical diagnosis of disseminated varicella infection was made, based on his history of contact with a person who had chickenpox, along with the appearance of lesions and pulmonary symptoms in the context of immunosuppression. Zuranolone (INN; developmental code SAGE-217) is an investigational medication, which is under development by SAGE Therapeutics for the treatment of major depressive disorder, postpartum depression, essential tremor, Parkinson's disease, insomnia, and seizures. It is a synthetic, orally active, inhibitory pregnaneneurosteroid, and acts as a positive allosteric modulator of the GABAA receptor. The drug was developed as an improvement of allopregnanolone (brexanolone) with high oral bioavailability and a biological half-life suitable for once-daily administration. Trial of SAGE-217 in Patients with Major Depressive Disorder Altered neurotransmission of γ-aminobutyric acid (GABA) has been implicated in the pathogenesis of depression. Whether SAGE-217, an oral, positive allosteric modulator of GABA type A receptors, is effective and safe for the treatment of major depressive disorder is unknown. In this double-blind, phase 2 trial, we enrolled patients with major depression and randomly assigned them in a 1:1 ratio to receive 30 mg of SAGE-217 or placebo once daily. The primary end point was the change from baseline to day 15 in the score on the 17-item Hamilton Depression Rating Scale (HAM-D; scores range from 0 to 52, with higher scores indicating more severe depression). Secondary efficacy end points, which were assessed on days 2 through 8 and on days 15, 21, 28, 35, and 42, included changes from baseline in scores on additional depression and anxiety scales, a reduction from baseline of more than 50% in the HAM-D score, a HAM-D score of 7 or lower, and a Clinical Global Impression of Improvement score of 1 (very much improved) or 2 (much improved) (on a scale of 1 to 7, with a score of 7 indicating that symptoms are very much worse). The mean HAM-D score at baseline was 25.2 in the SAGE-217 group and 25.7 in the placebo group. On day 15, the least-squares mean change from baseline in HAM-D score was −17.4±1.3 points in the SAGE-217 group and −10.3±1.3 points in the placebo group (least-squares mean difference in change, −7.0; 95% confidence interval [CI], −10.2 to −3.9; P<0.001). At each time point from day 2 through day 28, the unadjusted 95% confidence intervals for the between-group difference in the change from baseline in HAM-D scores did not include zero, and the differences were generally in the same direction as those of the primary outcome, but the unadjusted 95% confidence intervals for days 35 and 42 included zero. At day 15, the least-squares mean change from baseline in the Bech-6 score was −40.7±3.3 points in the SAGE-217 group and −25.7±3.4 points in the placebo group (least-squares mean difference in change, −15.1 points; unadjusted 95% CI, −23.3 to −6.8). At day 15, the least-squares mean change from baseline in the MADRS score was −22.5±1.9 in the SAGE-217 group and −15.0±1.9 in the placebo group (least-squares mean difference in change, −7.6 points; unadjusted 95% CI, −12.3 to −2.8). Efficacy End Points. Scores on the 17-item Hamilton Depression Rating Scale (HAM-D) range from 0 to 52, with higher scores indicating more severe depression. The primary end point was the change in HAM-D score from baseline to day 15 (Panel A). � bars indicate ±1 SE. The percentage of patients who had a reduction from baseline in HAM-D score of more than 50% (Panel B) and the percentage of patients who had a HAM-D score of 7 or lower (Panel C) were secondary end points. The most common adverse events that occurred in at least 5% of patients in the SAGE-217 group were headache, dizziness, nausea, and somnolence Among patients with moderate-to-severe major depressive disorder, treatment with SAGE- 217 for 14 days resulted in a reduction in depressive symptoms, as assessed on the basis of the change in the HAM-D score from baseline to day 15 and of changes in secondary end-point assessments that also were generally in the same direction as those of the primary outcome. The trial was not designed to confirm findings beyond the 15-day assessment period. One patient reported euphoria as an adverse event, which suggests that in most patients the effect of SAGE-217 on alleviation of depressive symptoms was not related to a temporary feeling of euphoria. The assessment of scores on the Bech-6 subscale showed improvement in all core symptoms of depression among patients who received SAGE-217. The effect of SAGE-217 was similar among patients who received adjunctive treatment with conventional antidepressants and those who received SAGE-217 as monotherapy, although the number of patients in these groups was small, and the trial was not powered to assess this comparison. These findings may support a role for GABAA receptors in the pathophysiology of depression. On the basis of the pharmacologic properties of SAGE-217 as a positive allosteric modulator of GABAA receptors, somnolence and sedation may be expected adverse events, and these were among the most common adverse events in the trial. In conclusion, in this trial of SAGE-217, an oral, synthetic positive allosteric modulator of GABAA receptors, patients who received SAGE-217 had a greater reduction in depressive symptoms at day 15 than patients who received placebo. Larger and longer trials are necessary to determine the durability and safety of SAGE-217 in the treatment of depression. Krampfadern (von althochdeutsch krimpfan ‚krümmen‘; fremdwortlich Varix und Varize, Plural Varizen, von lateinisch varix) sind knotig-erweiterte (oberflächliche) Venen (Blutadern). Die Krankheit beim Vorliegen von Varizen heißt in der Fachsprache Varikose oder auch Varikosis. Betroffen sind die oberflächlichen Venen der Beine inklusive deren Hauptstämmen, der Vena saphena magna und Vena saphena parva. Die Ursache der idiopathischen Varikose liegt in einer angeborenen Venenwand- bzw. Bindegewebsschwäche. Keine Rolle spielen Sonne, Wärme, Übereinanderschlagen (Verschränken) der Beine. Das Blut wird durch die Muskelpumpe gegen die Schwerkraft zum Herzen transportiert. Bei Bewegung, z. B. dem Spazierengehen, verkürzen sich die Beinmuskeln und pumpen das Blut in Richtung Herz. Ein Rückfluss wird durch Segelklappen verhindert. Wenn durch Veranlagung die Venenwände schwach sind, das umgebende Gewebe wenig Druck aufbaut und die Bewegung der Beine fehlt, z. B. durch Tätigkeiten, die langes Stehen oder Sitzen erfordern, bleibt mehr Blut in den Beinen. Die Venen werden gedehnt, bis sie so weit sind, dass die Venenklappen sie nicht mehr verschließen – vergleichbar einem Tor mit zu großem Rahmen. An diesem Punkt kommt es zur Strömungsumkehr, auch Blow-out genannt: Das Blut fließt der Schwerkraft folgend Richtung Fuß, statt zum Herzen. Das Phänomen setzt sich über Jahre immer schneller, da mit jeder undichten Klappe mehr Blut in den Beinvenen steht, Richtung Fuß fort. Die Krampfadern entstehen durch einen Abfluss des Blutes über die oberflächlichen Beinvenen, die bei einer Varikosis gefüllter sind. Die Adern selbst sind ungefährliche Zeichen der venösen Überlastung, die auf Schlimmeres hinweisen: eine chronisch-venöse Insuffizienz mit den unten beschriebenen Symptomen. Im Vordergrund der operativen Therapie stehen heute minimalinvasive operative Verfahren, wobei zwischen Methoden der Unterbindung, der Entfernung und der Sklerosierung (Verklebung) von Venen unterschieden werden kann. Bei der endovenösen Lasertherapie, der endovenösen Radiofrequenztherapie und der Sklerotherapie wird die Innenauskleidung der betroffenen Venen (das Endothel) thermisch oder chemisch zerstört, so dass der Blutstrom unterbunden ist. Die Venen selbst werden nicht entfernt. Dabei gibt es im Wesentlichen drei grundlegende Verfahren. Einmal die endoluminalen Verfahren mit Laser (hier gibt es mehrere Anbieter, die alle mit einem ähnlichen System arbeiten) und dann das sogenannte VNUS-Closure-Fast-Verfahren, bei dem ein schlauchartiger Heizdraht in der Vene mit Strom erhitzt wird und so im direkten Kontakt die Venenwände thermisch schädigt. Das dritte Verfahren ist die Celon-FITT-Radiofrequenzmethode (RFITT = Radiofrequenz-induzierte
