ABSTRACT

Summary: Background. The human microbiome is important due to the impact it has on host immunologic development and allergy-associated diseases. This study aimed to investigate the impact of prenatal exposure to antibiotics on the incidence of atopic dermatitis (AD) in children at 18 months of age. Methods. Mothers were interviewed at baseline, in the maternity ward and by phone questionnaire after 18 months. Demographic data, mode of delivery, yoghurt consumption, antibiotic and other drug use during pregnancy, atopic history, diagnosis of AD and history of infections in the offspring were noted. Results. 385 mothers were interviewed at baseline. 231 (60%) mothers with 236 children responded at follow up. Cesarean section was reported in 116 (50.2%) deliveries while antibiotic use during pregnancy in 55/231 (23.8%) women. 43/236 (18.22%) infants were diagnosed with AD. Intravenous antibiotic use was associated with a 7.7 increased risk of AD diagnosis in the offspring (95%CI 1.23-48.27, p = 0.029). An increased odd for AD was recorded for mothers 30-40 years of age (OR 4.50, 95%CI 1.08-18.7, p = 0.039). No significant association between cesarean section and AD (p = 0.70) was recorded. In multivariate analysis, reported food allergy (OR 8.03, 95%CI 2.30-27.97, p = 0.001) and otitis media episodes in children (OR 3.76, 95%CI 1.60-8.83, p = 0.002) were significantly associated with AD diagnosis. Conclusions. An increased risk of AD was recorded only when antibiotics were given prenatally by intravenous route and in women between 30-40 years of age. Children with food allergy had an increased risk for AD. The relatively high percentage of cesarean sections was not a risk factor for AD.

ABSTRACT

BACKGROUND: Few studies have investigated the long-term outcomes of secukinumab in real-life psoriasis treatment where diverse patient profiles require a personalized approach. OBJECTIVES: To determine long-term performance of secukinumab in moderate-to-severe plaque psoriasis, and identify potential clinical factors predictive of sustained optimal response under real-world conditions. METHODS: In this 78-week, single-centre, retrospective study, effectiveness, safety and drug survival of secukinumab were evaluated. Effectiveness data are reported as observed. Co-primary endpoints were absolute Psoriasis Area and Severity Index (PASI) ≤3 at week 4, 16, 52, 78, and clinical predictors of PASI ≤3 and PASI100 responses at week 52 and 78. RESULTS: A total of 85 patients (75.3% male; mean age 48.6 years) were included. Absolute PASI ≤3 was achieved in 73% and 83% of patients at week 52 and 78, respectively. PASI 75/90/100 responses at week 52 (71.6%, 50.8%, and 40.3%, respectively) were sustained at week 78 (73.6%, 64.2%, and 45.3%, respectively). Median absolute PASI remained low at week 52/78 (0.9/0.6, respectively), while mean absolute PGA also sustained low (0-1) values after 16-78 weeks. Investigator's Global Assessment 0/1 response rate was maintained by week 52/78 (72/83%, respectively). The drug survival rate of secukinumab at week 78 was 79.1%. Treatment was discontinued in 17.9% of patients after an average of 41.7 weeks, mainly due to loss of effectiveness (10.4%). A total of 27% experienced adverse events, without critical safety concerns. Based on multivariate analysis, advanced body mass index (BMI) and presence of ≥3 comorbidities decreased the chance of achieving PASI ≤3 at week 78 [OR (95% CI) 0.78 (0.64-0.97); P = 0.024, and OR (95% CI) 0.045 (0.002-0.83); P = 0.037, respectively]. CONCLUSIONS: Secukinumab showed consistently high effectiveness in this real-life cohort, with an acceptable safety profile. Over time, persistence of PASI ≤3 response appears to be lower in patients with high BMI or multiple comorbidities.
