ABSTRACT
BACKGROUND: There is an urgent need for noninvasive tests to identify patients with psoriasis at risk of significant liver fibrosis. OBJECTIVES: To externally validate the ability of the Steatosis-Associated Fibrosis Estimator (SAFE) score to detect significant liver fibrosis in patients with psoriasis using transient elastography (TE) as a reference. METHODS: We analysed data from 75 patients with psoriasis, including TE, SAFE score, Fibrosis-4 Index (FIB-4) and Nonalcoholic Fatty Liver Disease Fibrosis Score (NFS). Significant liver fibrosis was defined as TE values ≥ 7.1 kPa. Diagnostic accuracy was assessed using the area under the receiver operating characteristic curve (AUROC). RESULTS: Fifteen patients (20%) exhibited significant liver fibrosis. The AUROCs for the SAFE and FIB-4 scores were 0.82 [95% confidence interval (CI) 0.67-0.97] and 0.62 (95% CI 0.45-0.79), respectively. The SAFE score outperformed the FIB-4 Index (P = 0.01) but was comparable with the NFS (P = 0.05) in predicting significant fibrosis. Using thresholds of < 0, 0 to < 100 and ≥ 100, the SAFE score categorized 36, 24 and 15 patients into low, intermediate and high-risk groups for significant fibrosis, respectively. The negative predictive value for excluding significant fibrosis with a SAFE score of < 0 was 94.4%, and the positive predictive value for diagnosing significant fibrosis with a SAFE score of > 100 was 53.3%. The duration of psoriasis, joint involvement and methotrexate treatment did not affect the diagnostic ability of the SAFE score whereas age of the patient did. CONCLUSIONS: The SAFE score demonstrated good accuracy in assessing clinically significant fibrosis among patients with psoriasis. This score should prove valuable for risk stratification and patient management in dermatology practice.

BACKGROUND: IgE-mediated food allergy (FA) affects health-related quality of life, and may cause life-threatening reactions. Few studies characterizing adult FA patients have been reported, especially first ever reaction (FER) in adult-onset. OBJECTIVE: We describe the characteristics of adult FA patients, especially FER and compare these characteristics between childhood- and adult-onset FA. METHODS: A cross-sectional study of all adult patients visiting the Allergy Clinic, Siriraj Hospital at the outpatient department between January 2009 to December 2019 was conducted. Demographic, clinical data, and first reaction in life data were collected. Adult-onset was defined as ≥ 18 years old. RESULTS: Of 711 patients visiting the clinic, 174 (24.4%) were FA with a median age of 31.0 years (interquartile range 24.0, 44.0 years); 29.3% were male. FA patients had significantly higher prevalence of sensitization to cockroach compared with non-FA patients (67.4% vs. 56.3%); p = 0.016). The three most common food triggers were shellfish (68.0%), wheat (28.7%), and fruit and vegetables (10.0%). Before diagnosis, 56.7% (97/171) experienced at least 1 food-related anaphylaxis. Of the 166 patients compared on age of onset, 127 (76.5%) were adult-onset. In FER, patients with adult-onset had significantly more reactions to fruit and vegetables, more respiratory system involvement, and more other systems involvement [OR 8.95 (1.13, 1157); p = 0.034; OR 3.15 (95%CI 1.30, 8.25), p = 0.011; OR 10.8 (1.35, 1404), p = 0.019, respectively]. In sensitivity analysis, the cardiovascular system involvement was also significantly more common [OR 2.78 (1.05, 9.15); p = 0.038]. CONCLUSIONS: Shellfish was the most common trigger foods in adult FA patients. In FER, anaphylaxis was common for adult-onset. Adult-onset FA patients also had more respiratory, cardiovascular, and other systems involvements than childhood-onset ones. FA awareness, early diagnosis, and proper management are encouraged. Further studies on the adult-onset food allergic patients are required.
