Less invasive surfactant administration reduces incidence of severe intraventricular haemorrage in preterms with respiratory distress syndrome: a cohort study.

Objective: Less invasive surfactant administration (LISA) has proved to safely improve morbidity in extreme preterms with respiratory distress syndrome (RDS). Its effect regarding intraventricular hemorrhage (IVH) remains controversial between most recent systematic reviews. We aimed to evaluate its effect over incidence of severe IVH in this population.

Severe and malignant hypertension are common in primary atypical hemolytic uremic syndrome.

Malignant hypertension is listed among the causes of secondary thrombotic microangiopathy, but pathogenic mutations in complement genes have been reported in patients with hypertension-induced thrombotic microangiopathy. Here we investigated the frequency and severity of hypertension in 55 patients with primary atypical hemolytic uremic syndrome (aHUS). A genetic analysis was performed in all patients, and funduscopic examination was performed in all the patients with Grades 2 and 3 hypertension.

Eculizumab in secondary atypical haemolytic uraemic syndrome.

Background: Complement dysregulation occurs in thrombotic microangiopathies (TMAs) other than primary atypical haemolytic uraemic syndrome (aHUS). A few of these patients have been reported previously to be successfully treated with eculizumab.

Methods: We identified 29 patients with so-called secondary aHUS who had received eculizumab at 11 Spanish nephrology centres.

Effect of pentoxifylline on renal function and urinary albumin excretion in patients with diabetic kidney disease: the PREDIAN trial.

Diabetic kidney disease (DKD) is the leading cause of ESRD. We conducted an open-label, prospective, randomized trial to determine whether pentoxifylline (PTF), which reduces albuminuria, in addition to renin-angiotensin system (RAS) blockade, can slow progression of renal disease in patients with type 2 diabetes and stages 3-4 CKD. Participants were assigned to receive PTF (1200 mg/d) (n=82) or to a control group (n=87) for 2 years.

Is it necessary to treat all asthmatic children with raised levels of exhaled nitric oxide?: treating the patient or the data.

Background: The aim of the present study is to assess whether a single determination of the fraction of exhaled nitric oxide (FENO), added to the measurements usually taken during a routine checkup, helps in the prediction of the recurrence of asthma attacks in controlled patients who are not receiving any baseline treatment; and whether or not treatment of the said latent inflammation is appropriate.

Methods: Observational study of prospective cohorts. Over a period of three months, data was collected from 28 patients (6 to 14 years) who met the conditions of the inclusion criteria, with a follow up appointment after six months.
