Background: The idea of convalescent plasma usage is to give passive immunity to the patients, so their immune system stands a good chance of combating the virus.this study will review 6 cases of eligible covid 19 patients that had been treated with convalescent plasma therapy in Basra covid 19 quarantine Objectives: to demonstrate efficacy and safety of convalescent plasma in the patient series that had been enrolled . Method: this study had pioneered a new method to collect up to 3,000 mL in one session by an off-label use of Spectra Optia Apheresis systems by TerumoBCT /Exchange set to collect convalescent plasma. In this study 250 mL convalescent plasma had been given each of the 6 patients, from one donor. respose in spo2,dyspnoea and tachypnoea was observed ,any reaction to plasma also had been monitored . Result: Our case series have demonstrated both safety and effectiveness of convalescent plasma. This study was successful in reaching our primary and secondary outcomes in all 6 patients (improvement in SpO2 and symptoms). With negligible difference in time of post transfusion response Conclusion: convalescent plasma is apperantly safe and effective, In this study 250 mL convalescent plasma had been given each of the 6 patients, from one donor using Therapeutic Plasma Exchange (TPE) protocol by Spectra Optia Apheresis system/TerumoBCT.

IntroductionPerfluoroalkyl and polyfluoroalkyl substances (PFAS) are a diverse group of compounds that have been used in hundreds of industrial applications and consumer products including aqueous film-forming foam (AFFF) for many years. Multiple national and international health and environmental agencies have accepted that PFAS exposures are associated with numerous adverse health effects. Australian firefighters have been shown to have elevated levels of PFAS in their blood, specifically perfluorooctane sulfonic acid (PFOS) and perfluorohexane sulfonic acid (PFHxS), due to the historical use of AFFF. While PFAS concentrations decline over time once the source of exposure has been removed, their potential adverse health effects are such that it would be prudent to develop an intervention to lower levels at a faster rate than occurs via natural elimination rates.Methods and analysisThis is a randomised controlled trial of current and former Australian firefighters in the Metropolitan Fire Brigade/Fire Rescue Victoria, and contractors, with previous occupational exposure to PFAS and baseline elevated PFOS levels. The study is investigating whether whole blood donation every 12 weeks or plasma donation every 6 weeks will significantly reduce PFAS levels, compared with a control group. We have used covariate-adaptive randomisation to balance participants’ sex and blood PFAS levels between the three groups and would consider a 25% reduction in serum PFOS and PFHxS levels to be potentially clinically significant after 12 months of whole blood or plasma donation. A secondary analysis of health biomarkers is being made of changes between screening and week 52 in all three groups.Ethics and disseminationThis trial has been approved by Macquarie University Human Research Ethics Committee (reference number: 3855), final protocol V.2 dated 12 June 2019. Study results will be disseminated via peer-reviewed publications and presentations at conferences.Trial registration numberAustralian New Zealand Clinical Trials Registry (ACTRN12619000204145).

Donor Plasma

The plasma samples of 34 primary donors (22 men and 12 women) for the first time given the plasma by automated plasmapheresis (control surveillance), and 54 active donors of blood plasma (40 men and 14 women) being donors with non-less 14 days interval between donations, have been examined. The active male donors’ plasma averaged at 18,63±1,71 with individual index fluctuations from 2 to 78, female donors’ – 14,09±1,95 with individual index fluctuations from 2 to 45. The method of plasma obtaining is a manual plasmapheresis method. The surveyed groups were homogeneous for age and sex. Hematologic and biochemical parameters of all those persons have been examined and, basing on the conclusion of the professionals, everyone was admitted to the plasma donation. The content of middle mass molecules in plasma were determined by method of N.I. Gabrieljan, V.I. Lipatovoj (1984). The content of biogenic amines free fractions in plasma were determined by fluorometric method of B.V. Mikhailichenko, S.V. Vydyborets (1999). Analysis of the results showed that in the donor plasma samples obtained by manual plasmapheresis level of middle mass molecules, histamine, serotonin is significantly higher. The significance of obtained results has also been discussed.

Dependent Variables

This study tested the efficacy of interventions to recruit new plasma donors among whole blood donors. A sample of 924 donors was randomized to one of three conditions: control; information only by nurse; and information plus self-positive image message by nurse (SPI). Participants in the control condition only received a leaflet describing the plasma donation procedure. In the two experimental conditions the leaflet was explained face-to-face by a nurse. The dependent variables were the proportion of new plasma donors and the number of donations at six months. Overall, 141 (15.3%) new plasma donors were recruited at six months. There were higher proportions of new plasma donors in the two experimental conditions compared to the control condition (P<.001); the two experimental conditions did not differ. Also, compared to the control condition, those in the experimental conditions (all Ps<.001) gave plasma more often (information only by nurse:  d=.26; SPI: d=.32); the SPI intervention significantly outperformed (P<.05) the information only by nurse condition. The results suggest that references to feelings of SPI such as feeling good and being proud and that giving plasma is a rewarding personal experience favor a higher frequency of plasma donation.
