Biologicals have transformed the management of severe disease phenotypes in psoriasis and are often prescribed in women of childbearing age. However, information on safety of biologicals in pregnancy are lacking. We conducted a systematic review and meta‐analysis aimed to describe the characteristics and pregnancy outcomes in women with psoriasis exposed to biologics within 3 months before or during pregnancy, and to estimate the pooled prevalence of spontaneous, elective and total abortions, and congenital malformations in their newborns. Bibliographic searches were performed in the PubMed, Embase, Scopus and Web of Science databases up to 14 April 2022. No restrictions on sample size or publication date were applied. Review performance complied with PRISMA guidelines, and two reviewers assessed randomized controlled trials and nonrandomized studies reporting pregnancy outcomes in women exposed to biologics indicated for psoriasis during the pre‐gestational and/or gestational period. Studies focusing on rheumatologic or gastroenterological immune‐mediated inflammatory diseases were excluded. Regardless of data heterogeneity, a random‐effects model was used to pool prevalence estimates. We included 51 observational studies, involving 739 pregnancies exposed to approved biologics for psoriasis. Administration was mostly (70.4%) limited to the first trimester, and the most common drug was ustekinumab (36.0%). The estimated prevalence of miscarriage was 15.3% (95% confidence interval [CI] 12.7–18.0) and elective abortions, 10.8% (95% CI 7.7–14.3). Congenital malformations occurred in about 3.0% (95% CI 1.6–4.8) of live births exposed to biologics during pregnancy. Altogether, exposure to biologics for psoriasis during pregnancy and/or conception does not seem to be associated with an increased risk of miscarriage/abortion or congenital malformations, showing similar rates to the general population. These results suggest that biologic drugs are safe and pose an acceptable risk to the foetuses/neonates.

Atopic dermatitis (AD) is the most common skin condition among pregnant women. However, there is limited information on the safety of biologicals during pregnancy. A systematic review and meta-analysis was conducted following the PRISMA guidelines to evaluate the effects of exposure to biologicals during pregnancy and/or preconception in women with AD, and to estimate the pooled prevalence of spontaneous abortions and congenital malformations in their newborns. MEDLINE, Embase, Scopus, and Web of Science to 31 May 2024 were searched to identify randomized controlled trials and non-randomized studies. To test the robustness of our findings, sensitivity analyses were performed. Fifteen observational studies involving 115 pregnant women with a mean age of 33.46 years (standard deviation [SD] 3.02 were included). All studies evaluated dupilumab. The mean duration of exposure to dupilumab during pregnancy was 27.52 weeks (SD 11.16). The weighted prevalence of spontaneous abortions was 18.9% (95% confidence interval 5.3 to 38.2). There were no reports of congenital malformations. The sensitivity analyses showed no significant differences in weighted prevalences. In conclusion, the current scientific evidence suggests that dupilumab is probably safe during pregnancy and preconception in women with AD, with no significant increase in the risk of miscarriage or congenital malformations compared to the general population. However, the results of this review are inconclusive due to the limited number of large, well-designed clinical studies.

The incidence of autoimmune bullous disorders has increased over the years, especially in elderly patients with multiple comorbidities, which has stimulated research into their association with other diseases. We performed a retrospective observational study used the Minimum Basic Data Set of hospital discharges to review records of patients admitted to Spanish public hospitals between 2016 and 2019 with a diagnosis of any autoimmune bullous disorder. The objectives were to describe the comorbidity profile and the clinical-epidemiological characteristics of patients with pemphigus and pemphigoid, and analyze the evolution of the incidence of these diseases. The study included 1950 patients with pemphigus and 5424 patients with pemphigoid. Incidence increased from 2016 to 2019. The main comorbidities were hypertension (40.19%) and diabetes mellitus (28.57%). Compared to patients with pemphigoid, those with pemphigus had a higher prevalence of neoplasms, osteoporosis, solid metastases and malignant lymphoma, while the prevalence of hypertension, kidney disease, diabetes, heart failure, dementia, chronic obstructive pulmonary disease and Parkinson’s disease was higher in the pemphigoid group (p < 0.05). Therefore, since autoimmune bullous disorders are associated with diverse comorbidities and their incidence has risen in recent years, the establishment of strategies to prevent the main comorbidities in these patients is justified.

The expansion of the COVID‐19 pandemic has been accompanied by numerous reports of chilblain‐like lesions (CLL) in different countries; however, the pathogenesis of these lesions is still unclear. This systematic review and meta‐analysis aimed to assess the prevalence of COVID‐19 (diagnosed using PCR and/or serology) in patients with CLL. We undertook a literature search in PubMed, Embase, and Scopus (to 15 March 2021), including studies that reported on the number of patients with CLL with positive PCR and/or serology for severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) or with a clinical suspicion of COVID‐19. Regardless of data heterogeneity, a random‐effects model was used to pool prevalence estimates. The meta‐analysis included 63 original studies, involving 2919 cases of CLL. A subgroup of these patients underwent diagnostic tests for COVID‐19 (PCR: n = 1154, 39.5%; serology: n = 943, 32.3%). The pooled prevalence of COVID‐19 in the overall sample and in the subgroup who were tested for COVID‐19 was, respectively: (i) positive PCR: 2.6% [95% confidence interval (CI) 1.9% to 3.4%] and 5.5% (95% CI, 3.7–7.7%); (ii) positive serology for SARS‐CoV‐2: 7.2% (95% CI, 4.7–10.2%) and 11.8% (95% CI, 7.9–16.3%); and (iii) positive PCR and/or serology, 15.2% (95% CI, 10.4–20.7%) and 7.5% (95% CI, 5.1–10.3%). Altogether, a small proportion of diagnostic tests for SARS‐CoV‐2, both PCR and serologies, show positive results in patients with CLL.

Background and Objective: The aim of this study was to analyze sex differences in risk factors associated with hospital mortality in patients with Fournier gangrene (FG). Materials and Methods: A retrospective population-based study (2016–2021) included FG hospitalizations in Spain. To identify the risk factors, we used multivariable logistic regression and reported adjusted odds ratios (aORs) with 95% confidence intervals (CIs). Results: There were 3644 admissions for FG during the study period (82.5% men and 17.5% women). The mean hospitalization rate per 1000 admissions/year was 0.23 for men and 0.05 for women, and the mean hospitalization rate per 100,000 inhabitants/year was 2.7 for men and 0.4 in women. The most common comorbidities were hypertension (44.9%) and diabetes mellitus (35.6%). The main complications were sepsis (22.1%), 29.8% were admitted to the intensive care unit and 16.1% died. Mortality was higher in women (aOR 1.32, 95% CI 1.07–1.63). The main independent risk factors for mortality in the entire sample were older age, neoplasms, chronic kidney disease, heart failure, sepsis, acute kidney injury, and admission to the intensive care unit. In women, they were older age, leukemia, sepsis, acute kidney injury, and admission to the intensive care unit. Conclusions: The overall FG mortality rate was slightly higher in women than in men, people aged >64 years, people with chronic kidney disease, sepsis, and acute kidney injury, and admission to the intensive care unit. The independent factors associated with mortality in women were similar in both sexes.

Background. Chagas disease (CD) is associated with excess mortality in infected people in endemic countries, but little information is available in non-endemic countries. The aim of the study was to analyze mortality in patients admitted to the hospital with CD in Spain. Methods. A retrospective, observational study using the Spanish National Hospital Discharge Database. We used the CD diagnostic codes of the 9th and 10th International Classification of Diseases to retrieve CD cases from the national public registry from 1997 to 2018. Results. Of the 5022 hospital admissions in people with CD, there were 56 deaths (case fatality rate (CFR) 1.1%, 95% confidence interval (CI) 0.8%, 1.4%), 20 (35.7%) of which were considered directly related to CD. The median age was higher in those who died (54.5 vs. 38 years; p < 0.001). The CFR increased with age, peaking in the 70–79-year (7.9%, odds ratio (OR) 6.27, 95% CI 1.27, 30.90) and 80–89-year (16.7%, OR 14.7, 95% CI 2.70, 79.90) age groups. Men comprised a higher proportion of those who died compared to survivors (50% vs. 22.6%; p < 0.001). Non-survivors were more likely to have neoplasms (19.6% vs. 3.4%; p < 0.001), heart failure (17.9% vs. 7.2%; p = 0.002), diabetes (12.5% vs. 3.7%; p = 0.001), chronic kidney failure (8.9% vs. 1.6%; p < 0.001), and HIV (8.9% vs. 0.8%; p < 0.001). In the multivariable analysis, the variables associated with mortality were age (adjusted OR (aOR) 1.05; 95% CI: 1.03, 1.07), male sex (aOR 1.79, 95% CI 1.03, 3.14), cancer (aOR: 4.84, 95% CI 2.13, 11.22), and HIV infection (aOR 14.10 95% CI 4.88, 40.73). Conclusions. The case fatality rate of CD hospitalization was about 1%. The mortality risk increased with age, male sex, cancer, and HIV infection.
