Time and Temperature Stability of TGF-β1, EGF and IGF-1 in 20% and 100% Human Serum.

Autologous serum eye drops (ASEDs) are used as a treatment for severe dry eye disease. The concentration and stability of various growth factors in ASEDs is determinative for their efficiency. We therefore assessed the concentrations of transforming growth factor beta 1 (TGF-β1), epidermal growth factor (EGF) and insulin-like growth factor 1 (IGF-1) in ASEDs following storage at 4-8, -20, -80 and -156 °C.

Using corneal confocal microscopy to track changes in the corneal layers of dry eye patients after autologous serum treatment.

Backround: In vivo corneal confocal microscopy allows the examination of each layer of the cornea in detail and the identification of pathological changes at the cellular level. The purpose of this study was to identify the possible effects of a three-month treatment with autologous serum eye-drops in different corneal layers of patients with severe dry eye disease using corneal confocal microscopy.

Methods: Twenty-six patients with dry eye disease were included in the study.

Apoptosis of conjunctival epithelial cells before and after the application of autologous serum eye drops in severe dry eye disease.

Aims: To assess the impact of autologous serum eye drops on the level of ocular surface apoptosis in patients with bilateral severe dry eye disease.

Methods: This prospective study was conducted on 10 patients with severe dry eye due to graft versus host disease (group 1) and 6 patients with severe dry eye due to primary Sjögren's syndrome (group 2). Impression cytology specimens from the bulbar conjunctiva were obtained before and after a three-month treatment with 20% autologous serum eye drops applied a maximum of 12 times a day together with regular therapy with artificial tears.

[Tear Osmolarity in Patients with Severe Dry Eye Syndrome Before and After Autologous Serum Treatment: a Comparison with Tear Osmolarity in Healthy Volunteers].

Introduction: Dry eye syndrome (DES) is a multifactorial disease of the tears and ocular surface. Recently, treatment with autologous serum eye drops (AS-ed) has been frequently used in these patients. Significant improvement correlates well with clinical, laboratory and subjective findings.

Failure of multiple antivirals to affect high HHV-6 DNAaemia resulting from viral chromosomal integration in case of severe aplastic anaemia.

We report a fifty-year-old woman presenting with severe aplastic anaemia (SAA) and prolonged high Human Herpesvirus 6 (HHV6) variant A DNAeamia detected by quantitative PCR. Multiple antiviral treatments failed to affect the HHV6 DNAemia and subsequent immunosuppressive treatment reached only partial improvement as judged by bone marrow examinations. The patient remained dependent on thrombocyte transfusions and G-CSF treatment.
