Cumulative incidence and risk of infection in patients with rheumatoid arthritis treated with janus kinase inhibitors: A systematic review and meta-analysis.

Patients with rheumatoid arthritis (RA) who receive immunosuppressive medications have a heightened risk of infection. The goal of our study was to calculate the pooled cumulative incidence and risk of infection in patients with RA treated with Janus kinase inhibitors (JAKi). The PubMed and EMBASE databases were queried for randomized controlled trials comparing patients with RA treated with JAKi (upadacitinib, baricitinib, tofacitinib, peficitinib, or filgotinib), defined as the treatment group, compared with control subjects, defined as participants receiving placebo or treatment regimen that was similar to that of participants in the treatment group, with the exception of JAKi. The primary study endpoint was the relative risk (RR) of any-grade and severe infection. The secondary endpoints were RR and cumulative incidence of opportunistic infections, herpes zoster, and pneumonia. The Stata v17 software was used for all data analysis. Results showed that treatment with baricitinib was associated with an increased risk of any-grade (RR 1.34; 95% CI: 1.19-1.52) and opportunistic (RR 2.69; 95% CI: 1.22-5.94) infection, whereas treatment with filgotinib (RR 1.21; 95% CI: 1.05-1.39), peficitinib (RR 1.40; 95% CI: 1.05-1.86) and upadacitinib (RR 1.30; 95% CI: 1.09-1.56) was associated with increased risk of any-grade infection only. Analysis based on type of infection showed a pooled cumulative incidence of 32.44% for any-grade infections, 2.02% for severe infections, 1.74% for opportunistic infections, 1.56% for herpes zoster, and 0.49% for pneumonia in patients treated with any JAKi during the follow-up period. Treatment with specific JAKi in patients with RA is associated with an increased risk of any-grade and opportunistic infections but not severe infection. Close clinical monitoring of patients with RA treated with JAKi is required to establish the long-term infection risk profile of these agents.

The efficacy and safety of different Janus kinase inhibitors as monotherapy in rheumatoid arthritis: A Bayesian network meta-analysis.

OBJECTIVE: This study aims to evaluate the efficacy and safety of JAK inhibitors in the treatment of patients with RA. METHODS: The databases CNKI, VIP, Wanfang, CBM, and PubMed, Embase, Cochrane Library and Web of Science were searched to identify relevant randomized controlled trials (RCTs), all from the time of database creation to April 2024. Screening, data extraction, and risk of bias assessment (using Review Manager-5.3 software) were independently performed by at least two authors. The network meta-analysis was conducted using R 4.1.3 software. PROSPERO registration number: CRD42022370444. RESULTS: Thirty-three RCTs included 15,961 patients The experimental groups involved six JAK inhibitors (filgotinib, tofacitinib, decernotinib, baricitinib, upadacitinib and peficitinib) and 12 interventions (different doses of the six JAK inhibitors), and the control group involved adalimumab (ADA) and placebo. Compared with placebo, all JAK inhibitors showed a significant increase in efficacy measures (ACR20/50/70). Compared with ADA, only tofacitinib, low-dose decernotinib, and high-dose peficitinib showed a significant increase in ACR20/50/70. Decernotinib ranked first in the SUCRA ranking of ACR20/50/70. In terms of safety indicators, only those differences between low-dose filgotinib and high-dose upadacitinib, low-dose tofacitinib and high-dose upadacitinib were statistically significant. Low-dose filgotinib ranked first in the SUCRA ranking with adverse events as safety indicators. Only the efficacy and safety of tofacitinib ranked higher among different SUCRA rankings. CONCLUSION: Six JAK inhibitors have better efficacy than placebo. The superior efficacy of decernotinib and safety of low-dose filgotinib can be found in the SUCRA. However, there are no significant differences in safety between the different JAK inhibitors. Head-to-head trials, directly comparing one against each other, are required to provide more certain evidence.

Bullous pemphigoid was confirmed by pathological examination and direct immunofluorescence. The patient was treated with topical corticosteroids, oral nicotinamide and minocycline hydrochloride. The lesions of bullous pemphigoid improved significantly after 7 days of treatment.Conclusions: Bullous pemphigoid is a rare adverse event following administration of secukinumab.

Assessment of disease control rate and safety of sorafenib in targeted therapy for advanced liver cancer.

OBJECTIVE: The clinical efficacy and safety of sorafenib in patients with advanced liver cancer (ALC) were evaluated based on transarterial chemoembolization (TACE). METHODS: 92 patients with ALC admitted to our hospital from May 2020 to August 2022 were randomly rolled into a control (Ctrl) group and an observation (Obs) group, with 46 patients in each. Patients in the Ctrl group received TACE treatment, while those in the Obs group received sorafenib molecular targeted therapy (SMTT) on the basis of the treatment strategy in the Ctrl group (400 mg/dose, twice daily, followed by a 4-week follow-up observation). Clinical efficacy, disease control rate (DCR), survival time (ST), immune indicators (CD3+, CD4+, CD4+/CD8+), and adverse reactions (ARs) (including mild fatigue, liver pain, hand-foot syndrome (HFS), diarrhea, and fever) were compared for patients in different groups after different treatments. RESULTS: the DCR in the Obs group (90%) was greatly higher to that in the Ctrl group (78%), showing an obvious difference (P < 0.05). The median ST in the Obs group was obviously longer and the median disease progression time (DPT) was shorter, exhibiting great differences with those in the Ctrl group (P < 0.05). Moreover, no great difference was observed in laboratory indicators between patients in various groups (P > 0.05). After treatment, the Obs group exhibited better levels in all indicators. Furthermore, the incidence of ARs in the Obs group was lower and exhibited a sharp difference with that in the Ctrl group (P < 0.05). CONCLUSION: SMTT had demonstrated good efficacy in patients with ALC, improving the DCR, enhancing the immune response of the body, and reducing the incidence of ARs, thereby promoting the disease outcome. Therefore, it was a treatment method worthy of promotion and application.

Mitigation of retinol-induced skin irritation by physiologic lipids: Evidence from patch testing.

BACKGROUND: There is a dearth of effective treatments to counter retinol-induced skin irritation. OBJECTIVE: This study aimed to investigate the efficacy of three potential mitigants: (i) phytosteryl/octyldodecyl lauroyl glutamate (PLG), (ii) a physiologic lipid mixture (PLM) comprised of ceramide three and cholesterol, and (iii) niacinamide, in ameliorating irritation instigated by retinol. METHODS: An occlusive human patch test, spanning 5 days, was undertaken on 18 Chinese participants aged between 23 and 40. It was designed as a randomized, double-blind, and vehicle-controlled study. Clinician erythema assessment (CEA) and instrumental evaluations were employed pre and post-test. Subsequently, a 4-week consumer in-use test, randomized and double-blind in nature, was executed to substantiate the soothing effects of PLG. RESULTS: Data from CEA and bioengineering assessments revealed that, in comparison to the vehicle control, both 2% PLG and 5% PLM notably curbed retinol-induced skin erythema and inflammation. Notably, PLG outperformed PLM. Conversely, 3% niacinamide did not offer relief against retinol-induced discomfort. The subsequent consumer in-use test affirmed that treatments with 2% PLG were better tolerated than those with the vehicle alone. CONCLUSION: To the best of our knowledge, this study represents the first confirmation that physiologic lipids effectively mitigate retinol-induced irritation. Given their capacity to counter retinol-induced irritation, physiologic lipids, particularly PLG, are recommended for incorporation in retinol regimens. Additionally, the Visia-CR a* value can serve as a robust objective measure for interpreting patch test outcomes.

Prophylactic nicotinamide treatment protects from rotenone-induced neurodegeneration by increasing mitochondrial content and volume.

Leber's hereditary optic neuropathy (LHON) is driven by mtDNA mutations affecting Complex I presenting as progressive retinal ganglion cell dysfunction usually in the absence of extra-ophthalmic symptoms. There are no long-term neuroprotective agents for LHON. Oral nicotinamide provides a robust neuroprotective effect against mitochondrial and metabolic dysfunction in other retinal injuries. We explored the potential for nicotinamide to protect mitochondria in LHON by modelling the disease in mice through intravitreal injection of the Complex I inhibitor rotenone. Using MitoV mice expressing a mitochondrial-tagged YFP in retinal ganglion cells we assessed mitochondrial morphology through super-resolution imaging and digital reconstruction. Rotenone induced Complex I inhibition resulted in retinal ganglion cell wide mitochondrial loss and fragmentation. This was prevented by oral nicotinamide treatment. Mitochondrial ultrastructure was quantified by transition electron microscopy, demonstrating a loss of cristae density following rotenone injection, which was also prevented by nicotinamide treatment. These results demonstrate that nicotinamide protects mitochondria during Complex I dysfunction. Nicotinamide has the potential to be a useful treatment strategy for LHON to limit retinal ganglion cell degeneration.

Revealing metabolic and biochemical variations via 1H NMR metabolomics in streptozotocin-nicotinamide-induced diabetic rats treated with metformin.

The increasing prevalence of lean diabetes has prompted the generation of animal models that mimic metabolic disease in humans. This study aimed to determine the optimum streptozotocin-nicotinamide (STZ-NA) dosage ratio to elicit lean diabetic features in a rat model. It also used a proton nuclear magnetic resonance (1H NMR) urinary metabolomics approach to identify the metabolic effect of metformin treatment on this novel rat model. Three different STZ-NA dosage regimens (by body weight: Group A: 110 mg/kg NA and 45 mg/kg STZ; Group B: 180 mg/kg NA and 65 mg/kg STZ and Group C: 120 mg/kg NA and 60 mg/kg STZ) were administered to Sprague-Dawley rats along with oral metformin. Group A diabetic rats (A-DC) showed favorable serum biochemical analyses and a more positive response toward oral metformin administration relative to the other STZ-NA dosage ratio groups. Orthogonal partial least squares-discriminant analysis (OPLS-DA) revealed that glucose, citrate, pyruvate, hippurate, and methylnicotinamide differentiating the OPLS-DA of A-MTF rats (Group A diabetic rats treated with metformin) and A-DC model rats. Subsequent metabolic pathway analyses revealed that metformin treatment was associated with improvement in dysfunctions caused by STZ-NA induction, including carbohydrate metabolism, cofactor metabolism, and vitamin and amino acid metabolism. In conclusion, our results identify the best STZ-NA dosage ratio for a rat model to exhibit lean type 2 diabetic features with optimum sensitivity to metformin treatment. The data presented here could be informative to improve our understanding of non-obese diabetes in humans through the identification of possible activated metabolic pathways in the STZ-NA-induced diabetic rats model.

Drug-Induced Liver Injury During a Glaucoma Neuroprotection Clinical Trial.

ABSTRACT: There are several ongoing, worldwide clinical trials with a cumulative target enrollment of over 1300 participants on the role of nicotinamide (a specific form of vitamin B3) as a therapeutic neuroprotective treatment for glaucoma. We describe a serious adverse event of drug-induced liver injury (DILI) likely related to the use of 3 g/day nicotinamide in a glaucoma clinical trial (clinicaltrials.gov identifier: NCT05695027) based in the United States. This report is important to share with the medical community, as other participants in glaucoma nicotinamide trials globally may have similar adverse events and many patients are using nicotinamide as a health supplement without medical supervision. We recommend that investigators, physicians, and patients remain vigilant about DILI as they seek novel vision-preserving neuroprotective therapies.

Efficacy and tolerability of a depigmenting gel serum comprising tranexamic acid, niacinamide, 4-butylresorcinol, phytic acid, and a mixture of hydroxy acids that targets the biological processes regulating skin melanogenesis.

BACKGROUND: The diverse causes of hyperpigmentation and complex nature of melanogenesis make it a challenge to manage. Current approaches either fail to deliver effective pigmentation control or have undesirable safety profiles that preclude their long-term use. AIMS: To evaluate the capacity of a cosmetic gel serum comprising tranexamic acid, niacinamide, 4-butylresorcinol, phytic acid, and a mixture of hydroxy acids that was designed to target the biological processes regulating skin melanogenesis to attenuate melanin production in vitro and reduce hyperpigmentation clinically. METHODS: Capacity to reduce melanin production in vitro was determined in melanocyte-containing reconstructed human epidermis (RHEm). Clinical efficacy and skin tolerability following twice daily application were assessed in 35 subjects with slight to moderate facial hyperpigmentation by instrumental (VISIA®-CR, Mexameter®) and clinical (mMASI, clinical score, IGA for hyperpigmentation) evaluation on D14, D28, D56, and D84. Maintenance of pigmentation control was followed up 1 month after cessation of treatment on D112. RESULTS: In RHEm in vitro, melanin production was reduced by 50.0% from baseline (D0) on D14 (p < 0.001) and by 67.0% on D21 (p < 0.001). Clinical reductions from baseline in brown spots count (-9.0%; p < 0.05), brown spots area (-16.7%; p < 0.001), and the melanin index (-11.4%; p < 0.001) were observed within 14 days of use. Statistically significant improvements in all clinical parameters were achieved by D28. By the end of treatment on D84, the number and surface area of brown spots were reduced by 28.4% and 40.3% compared to D0, respectively (p < 0.001, both), the melanin index was reduced by 31.1% (p < 0.001), mMASI was reduced by 63.0% (p < 0.001), and skin luminosity was increased by 79.0% (p < 0.001). IGA was reduced from 2.3 on D0 to 1.3 on D84 (p < 0.001). Improvements to all these parameters were maintained until D112, 1 month after termination of treatment. The product also demonstrated very good skin tolerability. CONCLUSION: A gel serum comprising tranexamic acid, niacinamide, 4-butylresorcinol, and hydroxy acids, designed to target the biological processes regulating skin melanogenesis, demonstrates rapid, robust, and sustained pigmentation control in this cohort.

Effects of Physalis peruviana L. (leaf crude extracts) on blood glucose and functional biomarkers in streptozotocin-nicotinamide-induced diabetic rats.

Promoting antidiabetic phytomedicines necessitates evidence-based preclinical investigations, particularly in animal models. The present study investigated the validity of using the streptozotocin-nicotinamide-induced type 2 diabetic (STZ/NA-induced T2DM) model to evaluate the effects of Physalis peruviana leaf crude extracts on controlling blood glucose levels and regulating physiological biomarkers in rats. Aqueous and methanol extracts dissolved in carboxymethylcellulose 1% (100, 200, mg/kg/day) were administered orally to STZ/NA-induced T2DM rats alongside glibenclamide (5 mg/kg) as the standard drug for four weeks. Blood samples were collected in fasting rats on days 1, 7, 14, 21, and 28 to measure glucose concentration, lipoprotein-cholesterol, and common serum biomarkers. Nutrition characteristics were also monitored, as well as the pancreas histology. Administration of STZ/NA in Wistar rats induced the T2DM significantly lower than did STZ alone (glycaemia 200 vs 400 mg/dL). The significant effects observed with plant extracts compared to untreated diabetic rats were blood glucose reduction (28-52 %), HDL-C increase, LDL-C decrease, ALAT increase, WBC increase, body weight gain (24%), and pancreas protection. The findings confirm the antidiabetic effect of P. peruviana in T2DM animal model.

Efficacy of ceramides and niacinamide-containing moisturizer versus hydrophilic cream in combination with topical anti-acne treatment in mild to moderate acne vulgaris: A split face, double-blinded, randomized controlled trial.

INTRODUCTION: Topical therapy is the mainstay treatment of acne, and topical retinoids such as tretinoin, tazarotene, and adapalene are recommended as the first-line therapy for mild to moderate acne. However, the cutaneous irritations may occur, and the dermocosmetics are recommended to prevent side effects of anti-acne drugs and adhere to treatment. Thus, this study aims to compare the efficacy and tolerability of ceramides and niacinamide-containing moisturizer (CCM) versus hydrophilic cream in combination with topical anti-acne treatment in mild to moderate acne vulgaris. METHODS: This was an 8-week, randomized, double-blinded, split face study in 40 patients assigned for topical anti-acne medications (5% benzoyl peroxide and 0.1% adapalene gel), then randomly applied CCM or hydrophilic cream. All patients were followed at week 0, 2, 4, and 8 for acne improvement, adverse reactions, biometric, and biophysical evaluation. RESULTS: CCM could significantly improve the non-inflammatory, inflammatory, and total acne lesions compared with hydrophilic cream after week 8 of treatment. Interestingly, there was an improvement of global worst score, hemoglobin index, melanin index, TEWL, skin hydration, sebum production, and skin surface pH, with no statistically significant differences between the two treatments. No serious side effects from clinical application of CCM and hydrophilic cream in mild to moderate acne vulgaris patients. CONCLUSION: Ceramide and niacinamide-containing moisturizer in combination with anti-acne medication can significantly improve acne lesions and decrease cutaneous irritations toward a satisfactory treatment outcome of mild to moderate acne vulgaris.

Combination of 5% cysteamine and 4% nicotinamide in melasma: Efficacy, tolerability, and safety.

BACKGROUND: Melasma is a chronic dermatosis that impacts the patient's quality of life and can present considerable challenges in terms of effective treatment. OBJECTIVE: To evaluate the effectiveness, tolerability, and safety of 5% cysteamine combined with 4% nicotinamide in female subjects with melasma. METHODS: This single-center, single-arm, prospective, open-label study evaluated patients with melasma using a combination cream of 5% cysteamine and 4% nicotinamide in a progressive regimen (60 min in the first month, 120 min in the second month, and 180 min in the third month). RESULTS: Overall, 35 treated subjects exhibited reduced modified Melasma Area and Severity Index (mMASI) (p < 0.001) and decreased MelasQoL scores (p < 0.001), accompanied by improved brightness, luminosity, homogeneity, and spot intensity (p < 0.001). Photographic and colorimetric analysis revealed smaller spots and improved homogeneity. LIMITATIONS: Adherence to progressive daily treatment could not be evaluated long-term. CONCLUSION: A combination cream comprising 5% cysteamine and 4% nicotinamide was effective, tolerable, and safe for treating melasma.

The effects of supramolecular nicotinamide combined with supramolecular salicylic acid on chloasma.

OBJECTIVE: To observe the efficacy and safety of supramolecular salicylic acid monotherapy and supramolecular nicotinamide in the treatment of chloasma. METHODS: A total of 28 female patients with chloasma diagnosed in the dermatology outpatient department of our hospital were randomly divided into an experimental group and a control group, with 14 cases in each group. All patients were treated with 30% supramolecular salicylic acid every 2 weeks, for a total of 8 treatments. The experimental group was treated with 10% supramolecular nicotinamide once in the morning and once in the evening, and the control group was a blank control. Before each exfoliation treatment, subjects were photographed with a VISIA skin detector, and skin image analysis and modified melasma area and severity index (MASI) score were performed. RESULTS: According to the MMASI decrease rate (%) before and after treatment, the effective rate of the experimental group was 64.29%, and the effective rate of the control group was 14.29%. The results of the GriffithS10 and VISIA were improved. During the whole treatment, there was one mild adverse reaction in both groups. CONCLUSION: Salicylic acid stripping combined with nicotinamide in the treatment of chloasma is safe and effective, can improve skin conditions, and can be widely applied in clinical practice.

A Prospective Study Exploring the Safety and Efficacy of Lenvatinib for Patients with Advanced Hepatocellular Carcinoma and High Tumor Burden: The LAUNCH Study.

PURPOSE: This study aimed to investigate the safety and efficacy of lenvatinib in real-world settings, including patients excluded from the REFLECT trial, a phase III trial that compared lenvatinib with sorafenib. PATIENTS AND METHODS: This multicenter, nonrandomized, open-label prospective study was conducted at 10 medical facilities in Japan (jRCTs031190017). Eligible patients had advanced hepatocellular carcinoma (HCC) and were suitable for lenvatinib therapy. The study included patients with high tumor burden (with >50% intrahepatic tumor volume, main portal vein invasion, or bile duct invasion), Child-Pugh B status, and receiving lenvatinib as second-line therapy following atezolizumab plus bevacizumab. RESULTS: From December 2019 to September 2021, 59 patients were analyzed (47 and 12 patients with Child-Pugh A and B, respectively). In patients with Child-Pugh A, the frequency of aspartate aminotransferase elevation was high (72.7%) in the high-burden group. No other significant ad verse events (AE) were observed even in second-line treatment. However, patients with Child-Pugh B had high incidence of grade ≥3 AE (100.0%) and high discontinuation rates caused by AE (33.3%) compared with patients with Child-Pugh A (80.9% and 17.0%, respectively). Median progression-free survival was 6.4 and 2.5 months and median overall survival was 19.7 and 4.1 months in Child-Pugh A and B, respectively. Lenvatinib plasma concentration was higher in patients with Child-Pugh B on days 8 and 15 and correlated with dose modifications and lower relative dose intensity. CONCLUSIONS: Lenvatinib is safe and effective for advanced HCC in patients with Child-Pugh A, even with high tumor burden. However, it carries a higher risk of AE and may not provide adequate efficacy for patients with Child-Pugh B status.

Oral Nicotinamide for Actinic Keratosis Prevention in Kidney Transplant Recipients: A Pilot Double-Blind, Randomized, Placebo-Controlled Trial.

BACKGROUND: Oral nicotinamide (NAM) has shown promise in preventing actinic keratoses (AKs) in trials based outside of the United States. We assessed the efficacy of oral NAM supplementation in kidney transplant recipients with a history of keratinocyte carcinoma. MATERIAL AND METHODS: Patients enrolled in a 2-week run-in phase, during which NAM 1000 mg was taken twice daily. After a washout period, patients who tolerated the run-in phase were randomized to NAM 500 mg twice daily or placebo. At baseline, 4, 8, and 12 months, dermatologists conducted full-body skin exams to document area-specific AKs. Routine lab work was collected to ensure the stability of renal allograft function. RESULTS: The dosage was reduced from 1000 to 500 mg due to gastrointestinal symptoms in the run-in phase. Patients were randomized to NAM (n = 10) or placebo (n = 11). At 12 months, mean AK count was 30.8 (95% CI -11.7-73.4) for NAM and 26.6 (95% CI 10.8-42.5) for placebo. The difference in percent AK count change at 12 months compared with baseline was 259.8% (95% CI -385.9 to 905.5) for NAM and 72.4% (95% CI -118.6 to 263.5) for placebo. The between-group difference in percent AK change was not significant (P = .38). There was no attrition in the placebo group and 40% attrition in the NAM arm. DISCUSSION: Nicotinamide did not decrease AK development among kidney transplant recipients. Limitations include drug tolerability, small sample size, and single-center trial nature.

Efficacy and safety analysis of TACE + Donafenib + Toripalimab versus TACE + Sorafenib in the treatment of unresectable hepatocellular carcinoma: a retrospective study.

OBJECTIVE: To compare the efficacy and safety of TACE combined with Donafenib and Toripalimab versus TACE combined with Sorafenib in the treatment of unresectable hepatocellular carcinoma (HCC), aiming to guide personalized treatment strategies for HCC and improve patient prognosis. MATERIALS AND METHODS: A retrospective analysis was conducted on the clinical data of 169 patients with unresectable advanced-stage HCC who underwent treatment at the Interventional Department of Wuhan Union Hospital from January 2020 to December 2022. Based on the patients' treatment strategies, they were divided into two groups: TACE + Donafenib + Toripalimab group (N = 81) and TACE + Sorafenib group (N = 88). The primary endpoints were objective response rate (ORR), disease control rate (DCR), overall survival (OS), and progression-free survival (PFS) of the two groups' tumors. The secondary endpoint was the occurrence of treatment-related adverse events in the two groups of patients. RESULTS: The TACE + Donafenib + Toripalimab group showed higher ORR and DCR compared to the TACE + Sorafenib group (66.7% vs. 38.6%, 82.6% vs. 68.2%, P < 0.05). The TACE + Donafenib + Toripalimab group also demonstrated longer median progression-free survival (mPFS) (10.9 months vs. 7.0 months, P < 0.001) and median overall survival (mOS) (19.6 months vs. 10.9 months, P < 0.001) compared to the TACE + Sorafenib group. When comparing the two groups, the TACE + Sorafenib group had a higher incidence of grade 3-4 hypertension (14.8% vs. 4.9%, P = 0.041), higher incidence of diarrhea (all grades) (18.2% vs. 7.4%, P = 0.042), and higher incidence of hand-foot syndrome (all grades) (26.1% vs. 12.3%, P = 0.032). CONCLUSION: TACE combined with Donafenib and Toripalimab demonstrates superior efficacy and safety in treating unresectable HCC patients. This combination therapy may serve as a feasible option to improve the prognosis of unresectable HCC patients.

A single-center, randomized, controlled study on the efficacy of niacinamide-containing body emollients combined with cleansing gel in the treatment of mild atopic dermatitis.

OBJECTIVE: To observe the effect of niacinamide-containing body emollients combined with a cleansing gel on the clinical symptoms of mild atopic dermatitis (AD) in adults. METHODS: From July 2022 to January 2023, adults with mild AD were enrolled at Huashan Hospital Affiliated to Fudan University using single-center, randomized and placebo-controlled methods. They were divided into three groups: the control group, treatment group 1 (T1) receiving niacinamide-containing body emollients alone, and treatment group 2 (T2) receiving emollients plus niacinamide-containing cleansing gel. All patients were orally administered 10 mg of ebastine tablets daily. AD severity (SCORAD score), peak pruritus numeric rating scale (PP-NRS), patient-oriented measure of eczema (POEM), dermatological quality of life index (DLQI) score, transepidermal water loss (TEWL), and stratum corneum water content (SCWC) were measured by the same dermatologist at days 0, 7, 14, and 28. RESULTS: A total of 122 patients were enrolled, including 38 in the control group, 42 in the T1 group and 42 in the T2 group. There were no obvious adverse reactions at the end of the study and the clinical scores and stratum corneum barrier of all the groups improved significantly relative to baseline. The SCORAD, PP-NRS, DLQI, TEWL and SCWC scores in T1 group (12.43 ± 3, 3.3 ± 0.9, 7.1 ± 2.33, 17.1 ± 9.12, 67.2 ± 21.46, seperately) and T2 group (11.17 ± 3.26, 3 ± 1.3, 6.5 ± 2.11, 16.3 ± 9.12, 69.4 ± 24.52, seperately) were significantly improved than the control group(15.1 ± 3.64, 4.3 ± 1.7, 9.5 ± 2.46, 21.2 ± 9.47, 52.7 ± 22.43, seperately) at the endpoint of the study, while compared the POEM scores, only T2 group showed the difference with control group (5.2 ± 1.4 vs. 6 ± 1.6). The epidermal barrier parameters of TEWL and SCWC in the T2 group (17.57 ± 5.24, 66.46 ± 21.38, seperately) were significantly better than that of the T1 (19.96 ± 4.45, 56.45 ± 20.48, seperately) and control group(21.89 ± 7.03, 51.56 ± 16.58, seperately) on the 14th day of follow-up. CONCLUSION: The use of niacinamide-containing body emollients can significantly improve the clinical symptoms, quality of life, and skin barrier function in patients with mild AD. The addition of niacinamide-containing cleansing gel can also affect the clinical efficacy at certain time points.

Patients' willingness to accept adverse event and cost tradeoffs from oral nicotinamide for reduced risk of non-melanoma skin cancer.

BACKGROUND: Non-immunosuppressed patients with a history of multiple non-melanoma skin cancers (NMSCs) taking oral nicotinamide supplementation experienced a 23% decrease in annual NMSC risk in a randomized clinical trial. Patient preferences for risks and costs associated with nicotinamide are unknown. OBJECTIVES: To understand how patients prioritize NMSC reduction, infection risk, and cost. METHODS: A sample of adults with history of ≥2 NMSC within the past five years undergoing Mohs procedure completed a discrete-choice experiment comprising two hypothetical treatments-characterized by varying reductions in NMSC incidence, increased severe infection risk, and cost-and no treatment. The data were analyzed with random-parameters logit models. RESULTS: A total of 203 subjects (mean age 71.5 years, 65.5% males) participated. For a 23% annual reduction in NMSC incidence, a 26% [95% CI: 8%-45%] annual increase in severe infection risk and $8 [95% CI: $2-14] monthly cost was acceptable. Outcomes across analyzed subgroups (before vs. during COVID pandemic, site of interview, less vs. more prior NMSCs) were similar. CONCLUSIONS: Patients were unwilling to accept high severe infection risks to obtain the reduction in NMSC incidence observed in a nicotinamide trial, suggesting that routinely recommending nicotinamide may run counter to some patients' preferences.

[Efficacy and safety of Cytoflavin in the treatment of diabetic polyneuropathy: results of a multicenter, double-blind, placebo-controlled, randomized CYLINDER study]. / Effektivnost' i bezopasnost' primeneniya Tsitoflavina v terapii diabeticheskoi polineiropatii: rezul'taty mnogotsentrovogo dvoinogo slepogo platsebo-kontroliruemogo randomizirovannogo issledovaniya TsILINDR.

OBJECTIVE: The purpose of the present double-blind, placebo-controlled, randomized clinical trial was to evaluate the efficacy and safety of Cytoflavin in patients with diabetic polyneuropathy (DPN). MATERIAL AND METHODS: Investigational therapy was administered in two steps: intravenous infusions of experimental drug/placebo for 10 days followed by oral administration for 75 days. In 10 clinical centers, 216 patients aged 45-74 years with a diagnosis of type 2 diabetes mellitus, symptomatic distal sensorimotor DPN, confirmed no earlier than 1 year before screening, on stable therapy (no change of drugs and doses) by oral hypoglycemic drugs, intermediate-acting, long-acting or extra-long-acting insulin, and/or GLP-1 receptor agonists. RESULTS: By the end of treatment, the change of the Total Symptom Score (TSS) in the experimental group was -2.65 points, in the placebo group -1.73 points (p<0.001). Improvement of symptoms in the experimental group was achieved regardless of the degree of compensation for type 2 diabetes (both in those with Hb1Ac <8.0% and in those with Hb1Ac ≥8.0%), but demonstrated better results in patients with less severe baseline symptoms (TSS <7.5). Improvement in the components of the TSS scale «paresthesia¼ and «numbness¼ occurred as early as on day 11 of therapy; by the end of treatment, a significant decrease in the «burning¼ component was also demonstrated. The experimental drug had a positive safety profile. CONCLUSION: Cytoflavin, intravenous solution and enteric-coated tablets (SPTF Polysan Ltd.) is indicated for the symptomatic treatment of DPN.
