COMPARISON OF MOLECULAR AND SEROLOGICAL TESTS FOR SEVERE ACUTE RESPIRATORY SYNDROME CORONAVIRUS 2 (SARS-COV-2) IN POST-EXPOSURE EMPLOYEES OF THE NEPHROLOGY DEPARTMENT.

OBJECTIVE: Introduction: A novel coronavirus SARS-CoV-2 RNA, detected by reverse-transcription polymerase chain reaction (RT-PCR) was identified as the cause of a cluster of pneumonia cases in Wuhan, China. It rapidly spread, at first in China, then resulting in an epidemic in other countries throughout the world. One of such controversial topics is the issue of diagnostics and interpretation of test for COVID-19. According to Polish and global guidelines, the basis for diagnosis is molecular testing - real-time reverse transcriptasepolymerase chain reaction (RT-PCR). Taking all these data into consideration, the aim of the study was to compare RT-PCR with serological test in our employees post-exposure. According to Polish and global guidelines, the basis for diagnosis is molecular testing, real-time reverse transcriptase-polymerase chain reaction (RT-PCR). The aim: To compare RT-PCR with serological test in our employees post-exposure. PATIENTS AND METHODS: Material and methods: 79 employees of the Clinic, 19 men and 60 women in the age range 27-69 years were evaluated. Tests were begun four days after information about the positive test in our "Employee 0" and lasted for 7 days. At first, we made RT-PCR tests on the specimen from nasopharyngeal swab. Then, we accomplished rapid antibodies tests. This test is based on the qualitative assessment of the presence of IgM and IgG antibodies by immunochromatography using a sample of capillary blood from the fingertip. RESULTS: Results: All the tests were negative. No employee developed symptoms during the 7-day follow-up after the end of the tests. CONCLUSION: Conclusions: As routine tests for patients have been implemented widely, but similar solutions for employees have not gained popularity. Use of personal protective equipment (PPE) e.g. facemask and shields, transparent screens, disposable medical uniforms, minimalization the contact time, increasing distance from both colleagues and patients (if possible), and strictly follow sanitary procedures largely contributed to the absence of illness in the surveyed group of employees.

HOME DIALYSIS DURING COVID-19 OUTBREAK - IT IS WORTH TO CONSIDER.

The epidemic with the new SARS-CoV-2 virus poses a serious threat to patients treated with renal replacement therapy. Besides clinical risk factors (such as numerous comorbidities, immune disorders), dialysis patients are additionally exposed to the virus through regular stays for several hours in a dialysis center and ambulance journeys. In such an epidemiological situation, it seems that peritoneal dialysis and home hemodialysis are good alternatives for treatment. Currently available telemedicine and medical technologies allow for effective renal replacement therapy also outside dialysis centers. Thanks to this, it is possible to limit the stay of patients in a medical facility to clinically justified situations. For this reason, increasing the number of patients treated with peritoneal dialysis, which is carried out at home and without contact with medical personnel, seems to be a good solution. Enabling patients to undergo home hemodialysis treatment, nowadays unavailable in Poland and establishing it as a guaranteed benefit in the health care system will enable renal replacement therapy to be adapted to the clinical condition and the need for isolation.
