How to Deal with the Issues of Fertility, Malignancies, and the Postfinasteride Syndrome while Prescribing Finasteride for Male Pattern Hair Loss

Oral finasteride represented a breakthrough for treatment of male pattern hair loss (MPHL), with clinical studies having demonstrated high efficacy of treatment and a favorable safety profile. And yet, fertility issues, malignancy, and postfinasteride syndrome have been concerns of users and prescribers of the drug. Pre-existing mental health disorder may put patients at an increased risk of nocebo, while the prevalence of personality disorders in subjects with MPHL is known to be higher than in the general population, specifically histrionic personality disorder. We devised a system for patient selection and risk assessment, including fertility issues, regular PSA determinations, and specific mental health assessment. For those who choose regular prostate cancer screening, the use of finasteride meaningfully reduces the risk of prostate cancer. While gynecomastia is a known, rare adverse effect of finasteride, so far, studies support the view that exposure to finasteride is not associated with male breast cancer risk. Patient understanding and involvement are central to optimal treatment selection and active patient role in treatment.

Effect of pulsed intravenous methylprednisolone with alternative low-dose prednisone on high-risk IgA nephropathy: a 18-month prospective clinical trial

Full-dose prednisone (FP) regimen in the treatment of high-risk immunoglobulin A nephropathy (IgAN) patients, is still controversial. The pulsed intravenous methylprednisolone combined with alternative low-dose prednisone (MCALP) might have a more favorable safety profile, which has not been fully investigated. Eighty-seven biopsy-proven IgAN adult patients and proteinuria between 1 and 3.5 g/24 h after ACEI/ARB for at least 90 days were randomly assigned to 6-month therapy: (1) MCALP group: 0.5 g of methylprednisolone intravenously for three consecutive days at the beginning of the course and 3rd month respectively, oral prednisone at a dose of 15 mg every other day for 6 months. (2) FP group: 0.8–1.0 mg/kg/days of prednisone (maximum 70 mg/day) for 2 months, then tapered by 5 mg every 10 days for the next 4 months. All patients were followed up for another 12 months. The primary outcome was complete remission (CR) of proteinuria at 12 months. The percentage of CR at 12th and 18th month were similar in the MCALP and FP groups (51% vs 58%, P = 0.490, at 12th month; 60% vs 56%, P = 0.714, at 18th month). The cumulative dosages of glucocorticoid were less in the MCALP group than FP group (4.31 ± 0.26 g vs 7.34 ± 1.21 g, P < 0.001). The analysis of the correlation between kidney biopsy Oxford MEST-C scores with clinical outcomes indicated the percentages of total remission was similar between two groups with or without M1, E1, S1, T1/T2, and C1/C2. More patients in the FP group presented infections (8% in MCALP vs 21% in FP), weight gain (4% in MCALP vs 19% in FP) and Cushing syndrome (3% in MCALP vs 18% in FP). These data indicated that MCALP maybe one of the choices for IgAN patients with a high risk for progression into ESKD.Trial registration: The study approved by the Chinese Clinical Trial Registry (registration date 13/01/2018, approval number ChiCTR1800014442, https://www.chictr.org.cn/).

Runx1 Messenger RNA Delivered by Polyplex Nanomicelles Alleviate Spinal Disc Hydration Loss in a Rat Disc Degeneration Model

Vertebral disc degenerative disease (DDD) affects millions of people worldwide and is a critical factor leading to low back and neck pain and consequent disability. Currently, no strategy has addressed curing DDD from fundamental aspects, because the pathological mechanism leading to DDD is still controversial. One possible mechanism points to the homeostatic status of extracellular matrix (ECM) anabolism, and catabolism in the disc may play a vital role in the disease’s progression. If the damaged disc receives an abundant amount of cartilage, anabolic factors may stimulate the residual cells in the damaged disc to secrete the ECM and mitigate the degeneration process. To examine this hypothesis, a cartilage anabolic factor, Runx1, was expressed by mRNA through a sophisticated polyamine-based PEG-polyplex nanomicelle delivery system in the damaged disc in a rat model. The mRNA medicine and polyamine carrier have favorable safety characteristics and biocompatibility for regenerative medicine. The endocytosis of mRNA-loaded polyplex nanomicelles in vitro, mRNA delivery efficacy, hydration content, disc shrinkage, and ECM in the disc in vivo were also examined. The data revealed that the mRNA-loaded polyplex nanomicelle was promptly engulfed by cellular late endosome, then spread into the cytosol homogeneously at a rate of less than 20 min post-administration of the mRNA medicine. The mRNA expression persisted for at least 6-days post-injection in vivo. Furthermore, the Runx1 mRNA delivered by polyplex nanomicelles increased hydration content by ≈43% in the punctured disc at 4-weeks post-injection (wpi) compared with naked Runx1 mRNA administration. Meanwhile, the disc space and ECM production were also significantly ameliorated in the polyplex nanomicelle group. This study demonstrated that anabolic factor administration by polyplex nanomicelle-protected mRNA medicine, such as Runx1, plays a key role in alleviating the progress of DDD, which is an imbalance scenario of disc metabolism. This platform could be further developed as a promising strategy applied to regenerative medicine.

A web-based survey on factors for unvaccination and adverse reactions of SARS-CoV-2 vaccines in Chinese postoperative patients with breast cancer

Background Vaccination against SARS-COV-2 has been the most important strategy for preventing infection of Coronavirus disease 2019 (COVID-19). Breast cancer is the most common malignancy in women, but there is a lack of research on the pandemics in postoperative patients with breast cancer. Objective To investigate the rate and factors for SARS-CoV-2 vaccination and adverse reactions after vaccination in postoperative patients with breast cancer. Methods A web-based questionnaire survey on SARS-CoV-2 vaccination in postoperative patients with breast cancer among women. Results A total of 947 online questionnaires were collected. Of these, 341 accepted SARS-CoV-2 vaccination, while 606 were not vaccinated. There were significant differences in age, current treatment, the time since surgery, and the symptoms of anxiety and depression between the two groups. We identified current treatment (OR=0.51 for endocrine therapy; 95% CI: 0.29-0.89), the time since surgery (OR=22.49 for 1-2 years; 95% CI: 12.31-41.10; OR=8.49 for 2-5 years ; 95% CI: 4.98-14.46; OR=1.79 for >5 years ; 95% CI: 1.11-2.89), and the symptoms of depression (OR=2.48; 95% CI: 1.19-5.15) as significant factors for unvaccination. The overall incidence of adverse reactions was 43.1%. The most common local and systemic adverse reactions were pain at the injection site (28.4%) and fatigue (8.8%), respectively. Conclusion Postoperative patients with breast cancer have a relatively lower rate of vaccination for SARS-CoV-2 than the general population. Receiving treatment, a shorter time since surgery and symptom of depression were associated with unvaccination. More importantly, a favorable safety profile of the vaccines is indicated.

Role of inositol and its isomers in glucose metabolism

Despite the chemical similarities between myo-inositol and D-chiro-inositol and their synergistic effects on insulin sensitivity, they serve different functions. Insulin resistance is one of the etiological factors in the development of polycystic ovary syndrome (PCOS), diabetes mellitus, metabolic syndrome, infertility, menstrual irregularities and ovulation disorders, pregnancy complications, in particular, gestational diabetes. Myo-inositol plays an important role in the insulin transfer and hormone synthesis in the ovaries, in oocyte maturation, fertilization, implantation and post-implantation development.Many studies confirm the positive effect of inositol isomers on metabolic, hormonal and reproductive disorders, both in the form of monotherapy and in combination with other drugs to enhance the therapeutic effect and bioavailability. Myo-inositol has a favorable safety profile. Studies have shown that in patients with PCOS myo-inositol improves ovarian function and fertility, reduces the manifestations of hyperandrogenism, insulin resistance and normalizes weight.Myo-inositol and D-chiro-inositol have different mechanisms of action on insulin sensitivity and have different functions. The balance of the two isomers ensures the normal secretion of hormones and ovarian functioning, but it is currently unknown what the optimal ratio of these two isomers due to the small number of high quality studies and the difficulty of studying their isolated action.There are currently different combinations of myo- and D-chiro-inisotol, but they also have not been supported by enough high quality studies. When prescribing various isomers of inositol, it should be remembered that doses above 4000 mg are the most studied in patients with PCOS, but D-chiro-inositol concentration above 1200 mg/day has undesirable effects. Most studies indicate that D-chiro-inositol value is increased in PCOS, therefore oocytes are more sensitive to its overdose, and combination drugs require more study. Currently, there is no consensus in the literature on the advantage of combined supplements of myo- and D-chiro-inositol compared to monotherapy with myo-inositol. Today, myo-inositol monotherapy is more researched and safer.

Long-Term Safety and Efficacy of Belimumab in Japanese Patients with SLE: a 7-Year Open-Label Continuation Study

Objectives Evaluate long-term safety, tolerability and efficacy of belimumab in Japanese patients with systemic lupus erythematosus (SLE). Methods This was a subgroup analysis of Japanese patients who completed studies BEL113750 or BEL112341 and were enrolled in a Phase 3, open-label extension study (BEL114333; NCT01597622). Eligible patients received intravenous belimumab 10 mg/kg every 28 days for ≤7 years. Primary endpoint: safety and tolerability. Secondary endpoints included SLE responder index (SRI)-4 response rate, SRI-4 components, severe SLE flare, use of corticosteroids/other SLE-related treatments. Analyses were based on observed data from first parent or current study belimumab dose through to study end. Results Of 71 Japanese patients enrolled, 69.0% completed the study. Overall, 98.6% patients had adverse events (AEs); 32.4% had serious AEs. The proportion of SRI-4 responders increased progressively (Year 1, Week 24: 40.9% [27/66]; Year 7, Week 48: 84.6% [11/13]) as did the proportion of SELENA-SLEDAI responders. The proportion of patients with no worsening in PGA (91.2−100.0%) and no new organ damage (92.6−100.0%) remained stable over time. Severe SLE flare was experienced by 11.3% (8/71) of patients. Corticosteroid and immunosuppressant use decreased over time. Conclusion : Favorable safety profile and treatment responses with belimumab were maintained for ≤7 years in Japanese patients with SLE.

Central muscle relaxants in rheumatology practice

The article describes the general principles of the treatment of musculoskeletal pain, discusses modern approaches to the treatment of osteoarthritis (OA) and nonspecific back pain (NBS). The issues discussed are: the efficacy and tolerability of the combined use of non-steroidal anti-inflammatory drugs (NSAIDs) of predominantly selective action (aceclofenac) and a centrally acting muscle relaxant (tolperisone) in the treatment of OA and NBS. Two clinical observations are presented that confirm the benefits of combined administration of NSAIDs and muscle relaxants in the treatment of OA and NBS. The efficacy and favorable safety profile of aceclofenac has been demonstrated in patients with comorbid diseases. Tolperisone has shown its efficacy both as a mean of controlling pain associated with muscle tension, and as an element of combination therapy not only for NBS, but also for OA.

Safety, Pharmacokinetics, and Pharmacodynamics of Oral Venglustat in Patients with Parkinson’s Disease and a GBA Mutation: Results from Part 1 of the Randomized, Double-Blinded, Placebo-Controlled MOVES-PD Trial

Background: Glucocerebrosidase gene (GBA) mutations influence risk and prognosis of Parkinson’s disease (PD), possibly through accumulation of glycosphingolipids, including glucosylceramide (GL-1). Venglustat is a novel, brain penetrant glucosylceramide synthase inhibitor. Objective: Evaluate venglustat pharmacology, safety, and tolerability in patients with PD and GBA mutations (GBA-PD). Methods: Part 1 of the phase 2 MOVES-PD trial (NCT02906020) was a randomized, double-blinded, placebo-controlled, dose-escalation study performed in six countries. Eligible participants included Japanese and non-Japanese patients aged 18–80 years with PD diagnosis and heterozygous GBA mutation. Participants were randomized to three doses of once-daily oral venglustat or placebo and were followed up to 36 weeks (Japanese participants: 52 weeks). Primary endpoint was venglustat safety and tolerability versus placebo. Secondary and exploratory endpoints included venglustat pharmacokinetics and pharmacodynamics. Results: Participants (N = 29) received venglustat (Japanese, n = 9; non-Japanese, n = 13) or placebo (n = 3; n = 4). Eight (89%) Japanese and 12 (92%) non-Japanese venglustat-treated participants experienced at least one adverse event (AE) versus two (67%) and four (100%) participants from the respective placebo groups. Most AEs were mild or moderate; no serious AEs or deaths occurred. Two venglustat-treated non-Japanese participants discontinued due to AEs (confusional state and panic attack). Over 4 weeks, venglustat exposure in plasma and cerebrospinal fluid (CSF) increased, and GL-1 levels in plasma and CSF decreased, both in a dose-dependent manner. At the highest dose, CSF GL-1 decreased by 72.0% in Japanese and 74.3% in non-Japanese participants. Conclusion: Venglustat showed favorable safety and tolerability in MOVES-PD Part 1 and target engagement was achieved in CSF.

In vitro additive effects of dalbavancin and rifampicin against biofilm of Staphylococcus aureus

Dalbavancin is a novel glycopeptide antibiotic approved for the treatment of acute bacterial skin and skin structure infections (ABSSSIs). It is characterized by a potent activity against numerous Gram-positive pathogens, a long elimination half-life and a favorable safety profile. Most recently, its application for the treatment of periprosthetic joint infections (PJIs) was introduced. The aim of this study was to proof our hypothesis, that dalbavancin shows superior efficacy against staphylococcal biofilms on polyethylene (PE) disk devices compared with vancomycin and additive behavior in combination with rifampicin. Staphylococcus aureus biofilms were formed on PE disk devices for 96 h and subsequently treated with dalbavancin, vancomycin, rifampicin and dalbavancin-rifampicin combination at different concentrations. Quantification of antibacterial activity was determined by counting colony forming units (CFU/ml) after sonification of the PE, serial dilution of the bacterial suspension and plating on agar-plates. Biofilms were additionally life/dead-stained and visualized using fluorescence microscopy. Dalbavancin presented superior anti-biofilm activity compared to vancomycin. Additive effects of the combination dalbavancin and rifampicin were registered. Dalbavancin combined with rifampicin presents promising anti-biofilm activity characteristics in vitro. Further in vivo studies are necessary to establish recommendations for the general use of dalbavancin in the treatment of PJIs.
