3. Real-World Experience With Proactive Therapeutic Drug Monitoring During Infliximab Reintroduction.

Abstract

Background: Interruptions in infliximab therapy are associated with the development of antibodies to infliximab (ATI), infusion reactions (IRs), and loss of response. Despite these challenges, recent observational studies suggest that reinitiating infliximab after a drug holiday can be safe and effective. We assessed the utility of our protocol for restarting infliximab using early serum infliximab and ATI measurements., Methods: A retrospective cohort study of patients restarted on infliximab after at least a 6-month drug holiday. The cohort was divided into 2 groups: a "therapeutic drug monitoring (TDM) group," those who had serum infliximab and ATI measured 1-3 weeks after first reinduction dose, and a "non-TDM group." Outcomes included results of TDM, occurrence of immediate IR (IIR) and delayed hypersensitivity reactions, and medication persistence at 14 weeks and 1 year., Results: About 76 patients were included: 49 in the TDM group and 27 in the non-TDM group. Of 76, 67 (88%) patients tolerated the first reinduction dose without IR. Formation of ATI was seen in 17 of 49 (35%) patients and was associated with longer drug holidays. Most did not experience IR during the entire therapy course-in 26 of 32 (81%) without ATI and 20 of 27 (74%) in the non-TDM group. Infliximab persistence at 14 weeks and 1 year was 76% and 57% for the cohort, respectively., Conclusion: Infliximab can be safely and effectively restarted after a drug holiday. We suggest performing TDM with a drug-tolerant assay 1-3 weeks after the first reinduction infusion as a means to identify patients at risk for severe IIR at the second dose., (© The Author(s) 2021.

4. Properties of triple helices formed by parallel-stranded hairpins containing 8-aminopurines.

Subjects
Amines chemistry, Base Sequence, Circular Dichroism, DNA metabolism, Electrophoretic Mobility Shift Assay, Guanine chemistry, Hot Temperature, Models, Molecular, Nuclear Magnetic Resonance, Biomolecular, Nucleic Acid Conformation, Nucleic Acid Denaturation, Oligonucleotides chemistry, Pyrimidines metabolism, Salts pharmacology, DNA chemistry, Guanine analogs & derivatives, Purines chemistry
Abstract

Parallel-stranded hairpins with a polypyrimidine sequence linked to a complementary purine carrying 8-aminopurines such as 8-aminoadenine, 8-aminoguanine and 8-aminohypoxanthine bind polypyrimidine sequences complementary (in an antiparallel sense) to the purine part by a triple helix. The relative stabilities of triplexes were assessed by UV-absorption melting experiments as a function of pH and salt concentration. Hairpins carrying 8-aminopurines give very stable triple helical structures even at neutral pH, as confirmed by gel-shift experiments, circular dichroism and nuclear magnetic resonance spectroscopy. The modified hairpins may be redesigned to cope with small interruptions in the polypyrimidine target sequence.

5. The effect of RU486 administered during the proliferative and secretory phase of the cycle on the bleeding pattern, hormonal parameters and the endometrium.

Abstract

Seventeen healthy women aged 24-45 years with regular menstrual periods, proven fertility and not using steroidal contraceptives or IUD were recruited for the study. The volunteers were followed during one control, one treatment and one follow-up cycle. Daily morning urine samples were obtained during the control and the treatment cycle. The samples were analysed with regard to pregnanediol glucuronide (P2-G), oestrone glucuronide (E1-G), oestradiol (E2), progesterone (P4), LH and creatinine. During the entire 3-month study the subjects kept a record of uterine bleeding and side effects. The subjects received 50 mg RU486 daily either on cycle days 7-10 (n = 7) or on cycle days 20-23 (n = 10). An endometrial biopsy was taken on cycle day 10 in the first group and on cycle days 21-28 in the second group of patients. Treatment during the proliferative phase caused significant prolongation of the cycle length due to a delay of the oestrogen and LH surge. However, once the oestrogen concentration started to increase, the remaining part of the cycle was normal. The length of the follow-up cycle was similar to that of the control cycle. The morphology of the endometrium did not differ from control samples taken from untreated women at the same time of the cycle. All ovulating women (n = 9) treated in the mid-luteal phase started to bleed on the 3rd to 4th day of the treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

6. Adrenocortical and gonadal steroids during sleep deprivation.

Abstract

Twelve healthy males were exposed to 48 hr of sleep deprivation under conditions of strictly controlled activity and of food and drink intake. During the experiment the subjects were isolated from external time cures, i.e. no daylight, clocks, etc. Plasma samples were obtained before and at the end of the vigil, as well as after 5 days of recovery. Samples were analyzed for adrenal and gonadal steroid hormones and for follicle-stimulating (FSH) and luteinizing hormones (LH). The levels of all unconjugated steroids studied (cortisol, 17-hydroxypregnenolone, 17-hydroxyprogesterone, androstenedione, dihydrotestosterone) were significantly lower at the end of the sleep deprivation period. Self-ratings of fatigue were significantly higher at the end of the deprivation period. After recovery, all values returned to base line. No changes were observed in the levels of FSH, LH, or most conjugated steroids. It was concluded that the results were not consistent with the view that sleep deprivation induces an emergency reaction with increased activation, but rather that it results in lower levels of both psychological and physiological activation.
