on behalf of the PENUT Trial Consortium* Objective To evaluate whether extremely low gestational age neonates (ELGANs) randomized to erythropoietin have better or worse kidney-related outcomes during hospitalization and at 22-26 months of corrected gestational age (cGA) compared with those randomized to placebo. Study designWe performed an ancillary study to a multicenter double-blind, placebo-controlled randomized clinical trial of erythropoietin in ELGANs. ResultsThe prevalence of severe (stage 2 or 3) acute kidney injury (AKI) was 18.2%. We did not find a statistically significant difference between those randomized to erythropoietin vs placebo for in-hospital primary (severe AKI) or secondary outcomes (any AKI and serum creatinine/cystatin C values at days 0, 7, 9, and 14). At 22-26 months of cGA, 16% of the cohort had an estimated glomerular filtration rate (eGFR) <90 mL/min/1.73 m 2 , 35.8% had urine albumin/creatinine ratio >30 mg/g, 23% had a systolic blood pressure (SBP) >95th percentile for age, and 40% had a diastolic blood pressure (DBP) >95th percentile for age. SBP >90th percentile occurred less often among recipients of erythropoietin (P < .04). This association remained even after controlling for gestational age, site, and sibship (aOR 0.6; 95% CI 0.39-0.92). We did not find statistically significant differences between treatment groups in eGFR, albumin/creatinine ratio, rates of SBP >95th percentile, or DBP >90th or >95th percentiles at the 2 year follow-up visit.Conclusions ELGANs have high rates of in-hospital AKI and kidney-related problems at 22-26 months of cGA.Recombinant erythropoietin may protect ELGANs against long-term elevated SBP but does not appear to protect from AKI, low eGFR, albuminuria, or elevated DBP at 22-26 months of cGA.

Summary The therapy algorithm for severe aplastic anaemia (sAA) is established but moderate AA (mAA), which likely reflects a more diverse pathogenic mechanism, often represents a treatment/management conundrum. A cohort of AA patients (n = 325) was queried for those with non‐severe disease using stringent criteria including bone marrow hypocellularity and chronic persistence of moderately depressed blood counts. As a result, we have identified and analyzed pathological and clinical features in 85 mAA patients. Progression to sAA and direct clonal evolution (paroxysmal nocturnal haemoglobinuria/acute myeloid leukaemia; PNH/AML) occurred in 16%, 11% and 1% of mAA cases respectively. Of the mAA patients who received immunosuppressive therapy, 67% responded irrespective of time of initiation of therapy while conservatively managed patients showed no spontaneous remissions. Genomic analysis of mAA identified evidence of clonal haematopoiesis with both persisting and remitting patterns at low allelic frequencies; with more pronounced mutational burden in sAA. Most of the mAA patients have autoimmune pathogenesis similar to those with sAA, but mAA contains a mix of patients with diverse aetiologies. Although progression rates differed between mAA and sAA (P = 0·003), cumulative incidences of mortalities were only marginally different (P = 0·095). Our results provide guidance for diagnosis/management of mAA, a condition for which no current standard of care is established.

Introduction of SFR and RPS was associated with significant reduction in NEC ≥ Stage II and the composite outcome of NEC ≥ Stage II /mortality in preterm infants.

Background: Excretion of albumin in urine, in the range of 30-300 mg/day is called microalbuminuria, which cannot be detected by routine urine tests. The presence of increased UAE (Urinary albumin excretion) signals an increase in the transcapillary escape rate of albumin and is therefore a marker of micro vascular disease. Thus, microalbuminuria is an early response to myocardial infarction.Methods: A prospective study of 50 patients of acute myocardial infarction was carried out to find out the sensitivity and the specificity of microalbuminuria in non-diabetic patients of acute STEMI; to verify the association between the level of microalbuminuria and the area of infarcts; and to establish the correlation of microalbuminuria with cardiac biomarkers.Results: Microalbuminuria test was positive in 92% patients in the study group and 20% subjects in the control group. The sensitivity of microalbuminuria in our study is 92% and the specificity is 80%. The level of Microalbuminuria does not statistically correlate with areas of myocardial infarction.Conclusions: Microalbuminuria is a non-specific yet highly sensitive marker of myocardial infarction and it can be used as an additional biochemical parameter in non-diabetic patients with acute myocardial infarction. Prognostic marker value of microalbuminuria appears unproved.
