Neither anti-SLA/LP nor anti-Ro52 Abs or their combination could specify a distinct group of AIH patients in terms of clinical characteristics, treatment response and outcome. Further studies are needed to clarify whether the newly discovered immunodominant epitopes of Ro52 antigen which were associated specifically with AIH have any clinical or pathogenetic significance in AIH.

The results of the study suggest that a high lactic acid level (≥ 1.4 mmol/L) is associated with significantly shorter overall survival in patients with metastatic non-small cell lung cancer and extensive stage small cell lung cancer. Hyperlactatemia is an independent predictor of poor survival in metastatic lung cancer patients.

The early detection of colorectal cancer with effective screening is essential for reduction of cancer-specific mortality. The addition of fecal DNA testing in the armamentarium of screening methods already in clinical use launches a new era in the noninvasive part of colorectal cancer screening and emanates from a large number of previous and ongoing clinical investigations and technological advancements. In this review, we discuss the molecular rational and most important genetic alterations hallmarking the early colorectal carcinogenesis process. Also, representative DNA targets-markers and key aspects of their testing at the clinical level in comparison or/and association with other screening methods are described. Finally, a critical view of the strengths and limitations of fecal DNA tests is provided, along with anticipated barriers and suggestions for further exploitation of their use.

SUMMARY BackgroundWe reported that combined presence of autoantibodies (Abs) against filamentous-actin (AFA) and a-actinin are specific for autoimmune hepatitis type 1 (AIH-1) diagnosis.
