Effect of Lactoferrin on Clinical Outcomes of Hospitalized Patients with COVID-19: The LAC Randomized Clinical Trial

As lactoferrin is a nutritional supplement with proven antiviral and immunomodulatory abilities, it may be used to improve the clinical course of COVID-19. The clinical efficacy and safety of bovine lactoferrin were evaluated in the LAC randomized double-blind placebo-controlled trial. A total of 218 hospitalized adult patients with moderate-to-severe COVID-19 were randomized to receive 800 mg/die oral bovine lactoferrin (n = 113) or placebo (n = 105), both given in combination with standard COVID-19 therapy. No differences in lactoferrin vs. placebo were observed in the primary outcomes: the proportion of death or intensive care unit admission (risk ratio of 1.06 (95% CI 0.63-1.79)) or proportion of discharge or National Early Warning Score 2 (NEWS2) ≤ 2 within 14 days from enrollment (RR of 0.85 (95% CI 0.70-1.04)). Lactoferrin showed an excellent safety and tolerability profile. Even though bovine lactoferrin is safe and tolerable, our results do not support its use in hospitalized patients with moderate-to-severe COVID-19.

Paroxetine is an effective treatment for refractory erythema of rosacea: Primary results from the Prospective Rosacea Refractory Erythema Randomized Clinical Trial

BACKGROUND

Patients with refractory erythema of rosacea have limited treatment options.

OBJECTIVE

To evaluate the efficacy and safety of a 12-week course of paroxetine for moderate-to-severe erythema of rosacea.

METHODS

In a multicenter, randomized, double-blinded, placebo-controlled trial, patients with refractory erythema of rosacea were randomly assigned (1:1) to receive paroxetine 25 mg daily or placebo for 12 weeks.

RESULTS

Overall, 97 patients completed the study (paroxetine: 49; placebo: 48). The primary end point was the proportion of participants achieving Clinical Erythema Assessment success (defined as Clinical Erythema Assessment score of 0, 1, or ≥2-grade improvement from baseline) at week 12; this was significantly greater in the paroxetine group than in the placebo group (42.9% vs 20.8%, P = .02). Some secondary end points were met, such as flushing success with point reductions ≥2 (44.9% vs 25.0%, P = .04) and improvement in overall flushing (2.49 ± 3.03 vs 1.68 ± 2.27, P = .047), burning sensation (46.9% vs 18.8%, P = .003), and depression (P = .041). The most reported adverse events associated with paroxetine were dizziness, lethargy, nausea, dyspepsia, and muscle tremors.

LIMITATIONS

Only a single-dosage regimen of paroxetine within a 12-week study was evaluated.

CONCLUSIONS

Paroxetine is an effective and well-tolerated alternative treatment for moderate-to-severe erythema of rosacea.

Influence of Lisdexamfetamine Dimesylate on Early Ejaculation-Results from a Double-Blind Randomized Clinical Trial

BACKGROUND

Among male sexual dysfunctions, erectile dysfunction and early ejaculation have the highest prevalence rates. Here, we tested the influence of lisdexamfetamine dimesylate (Vyas®) on early ejaculation. To this end, we performed a double-blind randomized clinical trial among males with early ejaculation.

METHODS

A total of 46 males with early ejaculation (mean age: 35.23 years) and in stable marital relationships with regular weekly penile-vaginal intercourse were randomly assigned either to the lisdexamfetamine dimesylate condition (30 mg) or to the placebo condition. Compounds were taken about six hours before intended penile-vaginal intercourse. At baseline and four weeks later at the end of the study, participants completed a series of self-rating questionnaires covering early ejaculation. Female partners also rated participants' early ejaculation profile.

RESULTS

Compared to the placebo condition, dimensions of early ejaculation improved over time in the lisdexamfetamine condition, though improvements were also observed in the placebo condition.

CONCLUSIONS

Among male adults in stable marital relationships with regular weekly penile-vaginal intercourse, lisdexamfetamine dimesylate improved dimensions of early ejaculation. Given that improvements were also observed in the placebo condition, psychological factors such as increased attention to early ejaculation and favorable expectations of the compound should be considered.

Minocycline 1.5% foam for the topical treatment of moderate to severe papulopustular rosacea: Results of 2 phase 3, randomized, clinical trials

BACKGROUND

Efficacious topical medications for rosacea are needed. FMX103 1.5% is a novel topical minocycline foam that may have therapeutic benefits in treating rosacea while minimizing systemic adverse effects due to its topical route of delivery.

OBJECTIVE

To determine the efficacy, safety, and tolerability of 12 weeks of treatment with FMX103 1.5% topical minocycline foam for papulopustular rosacea.

METHODS

Two 12-week, phase 3, randomized, multicenter, double-blind, vehicle-controlled, 2-arm studies were performed in patients with moderate to severe papulopustular rosacea.

RESULTS

Participants who received FMX103 1.5%, versus control individuals treated with vehicle, exhibited a significantly greater reduction in the number of inflammatory lesions (FX2016-11: -17.57 vs -15.65; P = .0031; FX2016-12: -18.54 vs -14.88; P < .0001) and higher rates of Investigator Global Assessment treatment success (FX2016-11: 52.1% vs 43.0%; P = .0273; FX2016-12: 49.1% vs 39.0%; P = .0077). No serious treatment-related treatment-emergent adverse events occurred.

LIMITATIONS

The generalizability of these data from a controlled clinical trial should be examined in a real-world setting.

CONCLUSIONS

FMX103 1.5% was efficacious for moderate to severe papulopustular rosacea and maintained a favorable safety profile.
