Pulse azathioprine and low-dose methotrexate vs. standard-dose methotrexate in treatment of patients with moderate-to-severe psoriasis: a randomized controlled trial.

BACKGROUND: Psoriasis is a common chronic, immune-mediated inflammatory skin disease. Despite the availability of several systemic therapeutic agents, treatment of psoriasis remains a challenge because of the associated adverse effects and/or the financial burden of these medications, given the chronicity of the disease. OBJECTIVES: We aimed to compare the efficacy and safety of combined pulse azathioprine (AZA) and low-dose methotrexate (MTX) vs. a conventional dose of MTX in patients with chronic plaque psoriasis. METHODS: In this randomized controlled trial, 67 patients with moderate-to-severe plaque psoriasis were randomized into two groups, receiving either combined pulse AZA (300 mg weekly dose) and low-dose MTX (10 mg weekly) or conventional-dose MTX (0.3 mg kg-1 per week) for 16 weeks. Patients were assessed for treatment response using the Psoriasis Area and Severity Index (PASI) score and for the development of any adverse effects at weeks 12 and 16, and for a further 3 months after stopping treatment. RESULTS: A statistically significantly higher proportion of the patients receiving combined pulse AZA and low-dose MTX achieved ≥ 90% improvement in PASI and 100% improvement (PASI 100) at week 12, and PASI 100 at week 16, compared with those receiving the conventional dose of MTX as monotherapy. No serious adverse events were reported during the entire study period in the two groups. CONCLUSIONS: Combination therapy using pulse AZA and low-dose MTX can be an efficacious treatment for moderate-to-severe plaque psoriasis, with a relatively good safety profile.

The Association Between Preoperative Insulin-Like Growth Factor 1 Levels and the Total Body Weight Loss in Women Post Laparoscopic Sleeve Gastrectomy.

BACKGROUND: Despite the well-described optimal initial clinical response of sleeve gastrectomy (SG) in the treatment of obesity, some patients do not achieve optimal initial clinical response. Insulin-like growth factor-1 (IGF-1) has currently shown an association with post-bariatric surgery weight loss. This study aimed to assess the IGF-1 levels in female patients with obesity, the change after surgery, and their association with the metabolic profile and weight loss after surgery. PATIENTS AND METHODS: This was a prospective study that was conducted on adult female patients who were recruited for SG. The patients underwent clinical and laboratory investigations that included the IGF-1 measurement. At the 1-year follow-up, the same clinical and laboratory measures were repeated. RESULTS: This study included 100 female patients. At the 1-year follow-up, there was a statistically significant reduction in body mass index (BMI) (p < 0.001), fasting HbA1C levels (p < 0.001), and triglycerides (p < 0.001), as well as a statistically significant increase in HDL (p < 0.001) and IGF-1 (p < 0.001). Multiple regression analysis revealed that, among the patients baseline characteristics, the significant predictors for the percentage of total weight loss (%TWL) were the patients' BMI (p < 0.001) and IGF-1 levels (p < 0.001). The ROC curve showed that an IGF1 cutoff value of ≤ 23 ng/ml detected suboptimal initial clinical response, with a sensitivity of 95.35% and a specificity of 100%. CONCLUSION: This study underscores the significant impact of SG on weight loss and metabolic improvements in female patients. Baseline IGF-1 levels emerged as a crucial predictor of optimal initial clinical response.
