RESUMEN

INTRODUCTION: The Baveno VI consensus guidelines and an expanded algorithm suggest that transient elastography (TE) and platelet (PLT) count can be used to identify patients with cirrhosis who can avoid esophagogastroduodenoscopy (EGD). The primary aims of this study were to assess the ability of a simple algorithm, which uses only laboratory parameters, to predict medium/large esophageal varices (EV) in patients with hepatitis C virus (HCV) and cirrhosis from the Rete Sicilia Selezione Terapia-HCV (RESIST-HCV) cohort and to compare the performance of the algorithm with Baveno VI and Expanded Baveno VI criteria. The secondary aim was to assess the role of TE in ruling out large EV. METHODS: In total, 1,381 patients with HCV-associated cirrhosis who had EGD and TE within 1 year of starting treatment with direct-acting antivirals were evaluated. Using multivariate logistic analysis, laboratory variables were selected to determine which were independently associated with medium/large EV to create the RESIST-HCV criteria. These criteria were tested in a training cohort with patients from a single center (Palermo) and validated with patients from the 21 other centers of the RESIST-HCV program (validation cohort). RESULTS: In the entire cohort, medium/large EV were identified in 5 of 216 patients (2.3%) using the Baveno VI criteria and 13 of 497 patients (2.6%) using the Expanded Baveno VI criteria. PLT count and albumin level were independently associated with medium/large EV. The best cut-off values were a PLT count greater than 120 × 10 cells/µL and serum albumin level greater than 3.6 g/dL; negative predictive values (NPVs) were 97.2% and 94.7%, respectively. In the training cohort of 326 patients, 119 (36.5%) met the RESIST-HCV criteria and the NPV was 99.2%. Among 1,055 patients in the validation cohort, 315 (30%) met the RESIST-HCV criteria and the NPV was 98.1%. Adding TE to the RESIST-HCV criteria reduced the avoided EGDs for approximately 25% of patients and the NPV was 98.2%. DISCUSSION: The "easy-to-use" RESIST-HCV algorithm avoids EGD for high-risk EV screening for more than 30% of patients and has the same performance criteria as TE. Using these criteria simplifies the diagnosis of portal hypertension.

RESUMEN

Tuberculosis (TB) is one of the leading causes of death worldwide. Over the last decades, TB has also emerged in the pediatric population. Epidemiologic data of childhood TB are still limited and there is an urgent need of more data on very large cohorts. A multicenter study was conducted in 27 pediatric hospitals, pediatric wards, and public health centers in Italy using a standardized form, covering the period of time between 1 January 2010 and 31 December 2012. Children with active TB, latent TB, and those recently exposed to TB or recently adopted/immigrated from a high TB incidence country were enrolled. Overall, 4234 children were included; 554 (13.1%) children had active TB, 594 (14.0%) latent TB and 3086 (72.9%) were uninfected. Among children with active TB, 481 (86.8%) patients had pulmonary TB. The treatment of active TB cases was known for 96.4% (n = 534) of the cases. Overall, 210 (39.3%) out of these 534 children were treated with three and 216 (40.4%) with four first-line drugs. Second-line drugs where used in 87 (16.3%) children with active TB. Drug-resistant strains of Mycobacterium tuberculosis were reported in 39 (7%) children. Improving the surveillance of childhood TB is important for public health care workers and pediatricians. A non-negligible proportion of children had drug-resistant TB and was treated with second-line drugs, most of which are off-label in the pediatric age. Future efforts should concentrate on improving active surveillance, diagnostic tools, and the availability of antitubercular pediatric formulations, also in low-endemic countries.

RESUMEN

BACKGROUND: There is limited information on pregnancy outcomes in women with HIV who are of a more advanced maternal age. METHODS: Data from a national observational study in Italy were used to evaluate the risk of nonelective cesarean section, preterm delivery, low birthweight, major birth defects, and small gestational age-adjusted birthweight according to maternal age (<35 and ≥35 years, respectively). RESULTS: Among 1,375 pregnancies with live births, 82.4% of deliveries were elective cesarean sections, 15.8% were nonelective cesarean sections, and 1.8% were vaginal deliveries. Rates of nonelective cesarean section were similar among mothers ≥35 and <35 years (odds ratio [OR], 1.22; 95% CI, 0.90-1.65;P = .19). Preterm delivery and low birthweight were significantly more common among women ≥35 years in univariate but not in multivariate analyses. Newborns from women ≥35 and <35 years showed no differences inZ scores of birthweight, with a similar occurrence of birthweight <10th percentile (12.1% vs 12.0%; OR, 1.02; 95% CI, 0.71-1.46;P = .93). The overall rate of birth defects was 3.4% (95% CI, 2.4-4.4), with no differences by maternal age (≥35 years, 3.5%; <35 years, 3.3%; OR, 1.05; 95% CI, 0.56-1.98;P = .88). DISCUSSION: In this study of pregnant women with HIV, older women were at higher risk of some adverse pregnancy outcomes, such as preterm delivery and low birthweight. The association, however, did not persist in multivariable analyses, suggesting a role of some predisposing factors associated with older age.

RESUMEN

SCOPE: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has become pandemic, reaching almost one million death worldwide. At present standard treatment for coronavirus disease 2019 (COVID-19) is not well defined because the evidence, either from randomized or observational studies, with conflicting results, has led to rapid changes in treatment guidelines. Our aim was to narratively summarize the available literature on the management of COVID-19 in order to combine current evidence and interpretation of the data by experts who are treating patients in the frontline setting. METHODS: The panel conducted a detailed review of the literature and eventual press releases from randomized clinical trials for each possible available treatment. Inductive PubMed search waws performed for publications relevant to the topic, including all clinical trials conducted. The result was a flowchart with treatment indications for patients with COVID-19. IMPLICATIONS: After 6 months of a pandemic situation and before a possible second coronavirus wave descends on Europe, it is important to evaluate which drugs proved to be effective while also considering that results from many randomized clinical trials are still awaited. Indeed, among treatments for COVID-19, only glucocorticoids have resulted in an association with a significant decrease in mortality in published randomized controlled trials. New therapeutic strategies are urgently needed.

RESUMEN

OBJECTIVE: To evaluate the impact of Hepatitis B virus (HBV) coinfection on response to antiretroviral treatment in pregnant women with HIV. METHODS: Retrospective analysis of a large case series of pregnant women with HIV in Italy; outcome measures were CD4 changes, HIV viral load, and main pregnancy outcomes (preterm delivery, low birthweight, intrauterine growth restriction, mode of delivery, and major birth defects). RESULTS: Rate of HBV coinfection among 1462 pregnancies was 12.0%. Compared to the HBV-uninfected, HBV-coinfected women had a significantly lower median CD4 cell gain between first and third trimester (26.5 vs. 60 cells/mm3, p = 0.034), with similar rate of undetectable (<50 copies/ml) HIV-RNA at third trimester (70.5% vs. 65.2%, p = 0.229), and no differences in all the main maternal and infant outcomes. A multivariable linear regression analysis identified four variables significantly and independently associated with a lower CD4 response in pregnancy: HBV coinfection (-35 cells/mm3), being on antiretroviral treatment at conception (-59.7 cells/mm3), AIDS status (-59.8 cells/mm3) and higher first CD4 levels in pregnancy (-0.24 cells per unitary CD4 increase). CONCLUSIONS: HBV coinfection had no adverse influence on the main pregnancy outcomes or on HIV viral load suppression in late pregnancy but was associated with a significantly reduced CD4 response in pregnancy. This effect might have clinical relevance, particularly in women with advanced immune deterioration.

RESUMEN

This retrospective multicentre study aims to evaluate the clinical and epidemiological features of HCV infection in a cohort of immigrants in Italy. Tests were carried out on 194 HCV positive subjects, who represented 5.7% of the participants at baseline screening: the virological (viral load, genotype) and biochemical appearance of their infection was determined, and the disease was staged by histological examination in the patients who had indicated their willingness. Standard therapy (peg-interferon + ribavirin) was implemented in patients who agreed to undergo treatment. The majority of immigrants were of East-European origin (48.4%), females were globally slightly predominant and the average age was 41.4 years. Of the 194 patients, 119 (63.1%) proved to be viraemic: genotype 1 was the most frequent, followed by genotype 4, the latter mainly in African patients. The histological staging of liver disease conducted in 25 patients showed mild hepatitis in 13 subjects, moderate/severe hepatitis in eight subjects and cirrhosis in four. Although 45 out of 119 patients (37.8%) with determinable HCV RNA agreed to undergo treatment, 11 of them independently stopped taking medication before the course of therapy was completed, without any significant side effects. At the sixth month of follow-up, the overall sustained virological response (SVR) was shown by 22/45 patients (48.8%). In our study, migrant populations had higher rates of HCV-related chronic hepatitis than the indigenous population; in some cases the infections were contracted in the country of origin, but in others the infection took place in Italy. The most commonly represented genotype, besides 1, was 4, especially among Africans. The therapeutic management of immigrants proved to be very difficult, mostly but not exclusively because of social factors.
