To determine expression levels of urokinase-type plasminogen activator (uPA), soluble urokinase-type plasminogen activator receptor (suPAR), plasminogen activator inhibitor-1 (PAI-1) in plasma and to identify gene polymorphisms specific to patients with pelvic inflammatory disease (PID) and healthy controls. ⋯ Increased plasma suPAR could be a biological marker for the diagnosis of PID and may reflect a new focus in targeted therapy for pelvic inflammatory disease.

Acute kidney injury (AKI) is a dynamic process that can involve inflammatory, hypoxic, and structural changes to the kidney. We evaluated a multiplex panel of markers representing different AKI mechanisms as a tool to provide integrated assessment of AKI status in a single assay. ⋯ The multiplex assay is reliable for simultaneous quantitation of CysC, IL-18, KIM-1 and NGAL in human urine, and performs at levels sufficient for clinical application. The observed differences in biological variability and baseline levels suggest that clinical strategies to detect AKI will need to vary depending upon the specific markers used.

Alcohol ketoacidosis is a frequently missed diagnosis, but is well described in the literature. We present a case of ketoacidosis, likely alcohol ketoacidosis, in a 40 y-old chronic alcoholic patient. The detection of trace serum isopropanol prompted a discussion of alcohol ketoacidosis versus toxic isopropanol ingestion or a combination of both, including comparisons with citations in current literature. ⋯ Ketoacidosis with an increased anion gap in the absence of hyperglycemia or glycosuria in a chronic alcoholic patient should prompt the evaluation for alcohol ketoacidosis. Trace serum isopropanol may be worrisome for a toxic ingestion, but this finding in severe ketoacidosis may be explained by the reversible action of the enzyme alcohol dehydrogenase. Markedly increased serum isopropanol with a low serum acetone:isopropanol ratio would be more indicative of a toxic isopropanol ingestion.

Circulating cell-free DNA levels are increased after trauma injury. This increase is higher since the first hours after trauma and may be related with primary outcome. A sensitive and reliable biomarker for patients at higher risk is needed to identify these patients to initiate early intervention. In this way, circulating DNA may be a possible biological marker after severe TBI. ⋯ In summary we showed that severe TBI is associated with elevated cf-DNA levels and we propose that cf-DNA decrease during the first 24h may predict patient outcome.

Fibromyalgia syndrome (FMS) is a common chronic widespread pain syndrome mainly affecting women. Genetic risk factors are known to contribute to the etiology of the syndrome. Clinical features show that FMS and familial Mediterranean fever (FMF) have some overlapping symptoms. Mediterranean fever (MEFV) gene has already been identified as being responsible for FMF. The aim of this study was to explore the frequency and clinical significance of missense mutations and a common polymorphism of MEFV gene in a cohort of Turkish patients with FMS. ⋯ The results of this study suggest that MEFV gene mutations and polymorphism are positively associated with predisposition to develop FMS. Further studies with larger populations will be required to confirm these findings.
