ABSTRACT
Background: Anticoagulation in continuous renal replacement therapy (CRRT) is essential to counteract the coagulation cascade activation, induced by the dialysis circuit. Heparin is the most widely used anticoagulant, followed by regional citrate anticoagulation (RCA). Aim: To determine the effectiveness and safety of anticoagulant treatment with citrate in CRRT. Material and Methods: Retrospective study of adults in CRRT hospitalized between the years 2014 and 2020 in critical units, who required change to RCA according to established protocols. Results: We studied 24 patients aged 63 ± 13 years (12 females). The reasons for admission were acute kidney injury (AKI) in 80% and stage 5 chronic kidney disease in 20%. The indication of RCA in 75% of patients was by coagulation of more than 3 circuits in 24 hours. The duration of the circuit in RCA was 18.5 ± 4.8 hours versus 11.9 ± 4.9 hours with heparin (p < 0.0001). There were 19 mild complications that did not affect the RCA. Conclusions: RCA is feasible to perform, it is a safe and efficient procedure if it is protocolized, allowing a longer duration of the dialysis circuit.
ABSTRACT
COVID-19 infection causes a systemic inflammatory response, which mainly presents as a febrile syndrome with respiratory involvement. We report a 37-year-old male who consulted for myalgia, nausea and epigastric pain lasting three days. On admission, he had crepitations at the lung bases. The initial laboratory showed a creatine kinase of 62,768 U/L, a LDH of 1,110 IU/L, a creatinine a 2.1 mg/dL, an aspartate aminotransferase of 1,347 IU/L, a D-dimer of 1,140 ng/mL, a ferritin of 1,201 ng/mL and a lymphocyte count of 810 cells/mm3. The chest CT scan was compatible with multifocal pneumonia, suggesting a COVID-19 infection. COVID-19 PCR was positive. The patient was managed with hydration, sodium bicarbonate, ceftriaxone, and azithromycin, with a good clinical response.

We report a 41-year-old man with HIV and a chronic obstructive pulmonary disease, treated for seven months with Fluticasone/Salmeterol and antiretroviral therapy (Lamivudine, Tenofovir, Atazanavir and Ritonavir). While using these medications, the patients developed a Cushing syndrome in a period of five months. After performing laboratory and imaging tests, it was concluded that the most probable cause of the syndrome was the interaction of inhaled steroids with Ritonavir. After discontinuing these medications the syndrome reverted in a period of 8 months.
