Autologous Plasma Treatment for Severe Dry Eye Patients

Use of Autologous Plasma Eyedrops Therapy for Severe Dry Eye in Singapore

A Visual Analogue Scale (VAS) will be applied to evaluate dry eye symptoms as described by Schaumberg et al. (Schaumberg 2007). As shown in Appendix B , the scores will be recorded separately for frequency and severity of dry eye symptoms. The patient will be asked to check a point on a 100-mm line that corresponds to the degree of the symptom. The location of the mark made by the patient for each question will be measured in mm from the left hand side of the 100 mm line and recorded in mm. For the follow up visits, which measured the distance between the mark made by the patient and the central anchor, a negative value will be recorded if left of the anchor and a positive value if right of the anchor. The higher the number, implying more symptoms and frequency of experiencing dry eye.
A global score will be calculated by multiplying the frequency score by the severity score and taking the square root of the result (to transform back to the original scale).

The CSF samples will be stored at -80°C until testing . CSF specimens will be prepared for GS and culture examinations by centrifugation at 3,000 rpm for 10 minutes at room temperaturetemperature.Culture will be performed by inoculating 1-2 drops of CSF sediment directly onto each of the following agar plates: horse-blood agar, Thayer-Martin agar, choc- olate agar and Sabouraud agar. Moreover, a broth tube (brain-heart infusion, BHI) will be inoculated with one drop of the sediment. Agar plates and broth will be incubated for 1 to 5 days at 35-37°C (with ~5% CO2, or in a candle-jar, for Thayer-Martin and chocolate agar) .
In addition to GS and culture method , India ink test and culture and latex agglutination test (LAT). LAT assay will be performed on CSF samples using Latex-antigen detection system kit..

The CSF samples will be stored at -80°C until testing . CSF specimens will be prepared for GS and culture examinations by centrifugation at 3,000 rpm for 10 minutes at room temperature. When dry, the smear will be fixed stained and finally observed by light microscopy with a 100X objective. Culture will be performed by inoculating 1-2 drops of CSF sediment directly onto each of the following agar plates: horse-blood agar, Thayer-Martin agar, choc- olate agar and Sabouraud agar. Moreover, a broth tube (brain-heart infusion, BHI) will be inoculated with one drop of the sediment.

Participants receive the HEAL antimicrobial solution for 2 hours once daily for a minimum of 5 consecutive days. Participants also receive the lock therapy once weekly for two additional weeks. Principle ingredients include minocycline, calcium disodium ethylenediaminetetraacetate (CaEDTA) and ethanol.

Infection

Antimicrobial solution, consisting of minocycline in combination with 30mg/ml of a chelator (EDTA) in 25% ethanol solution (HEAL solution), instilled in central venous catheter (CVC) catheter for 2 hours once daily for a minimum of 5 consecutive days. Lock therapy also received once weekly for two additional weeks.

Phase II Pilot Study to Estimate the Adverse Events Associated With the Lock Solution When Used to Salvage Central Venous Catheter (CVC) in the Setting of a Central Line Associated Bloodstream Infection (CLABSI)

Adverse events include symptoms of discomfort and pain associated with antimicrobial lock therapy (ALT) as well as mechanical complications. Evaluation of symptoms of discomfort related to the ALT including pain, feelings of discomfort, irritation, headache, facial redness or flushing, feeling of drowsiness, nausea, alcohol taste, dyspnea, arrhythmias. Participants given a 0 to 10 numeric discomfort scale. Toxicity due to persistent bacteremia monitored at 7 days.

Clinical assessment pertaining to central line associated bloodstream infection (CLABSI) performed within one month from end of treatment with lock therapy. Following criteria represent infectious failure to respond: Persistent signs and symptoms associated with CLABSI (fever) after 72 hours of initiation of active systemic antimicrobial therapy. Persistent bacteremia. Relapse of bacteremia during follow-up. Development of related deep seated infections during follow-up. Infection related death during acute illness, relapse or development of related deep seated complications.
