Introduction: Collapsing focal segmental glomerulosclerosis (cFSGS) refers to a distinct pattern of glomerulopathy characterized by a glomerular capillary collapse in a segmental global manner, podocyte proliferation, and tubulointerstitial injury. Viral infections like HIV, Parvovirus B19, and CMV seem to be prominent triggers for the development of a conventional histological pattern of FSGS. CMV-associated renal disease has been described only in transplant and immunocompromised patients. Case Description: Case 1 18-year-old female with history of asthma and HbSS disease presented with fever, nausea, vomiting, and neck pain Physical examination revealed a temperature of 102 F, icterus, negative meningeal signs, no rales, rhonchi or wheezing. Initial creatinine 0.2 mg/dL. COVID-19 PCR was negative but IgG antibodies positive. Patient developed non-oliguric AKI with fluid overload requiring hemodialysis. CMV IgM and CMV PCR were positive. She recieved antibiotic therapy and also ganciclovir. Biopsy revealed collapsing FSGS with acute tubular injury. A week after completion of ganciclovir therapy creatinine returned to baseline of 1.7 mg/dL. Case 2 40-year-old African American male with history of diabetes and asthma presented with fever, fatigue, epigastric pain and chest pain. Initial creatinine 1.2 mg/dl, hepatic function (AST 333 U/L, ALT 265 U/L, ALK 207 U/L), ferritin (13682 ng/ml), triglycerides (276 mg/dl) and proteinuria (urine protein /creatinine ratio: 2, urine albumin/creatinine:1016 mg/gm). Patient developed anuric renal failure which required hemodialysis. Biopsy revealed collapsing FSGS with diffuse podocyte effacement, moderate tubular atrophy, and interstitial fibrosis. CMV DNA antibodies were positive. Methylprednisolone and valganciclovir were started with patient creatinine trending down to 3.7 mg/dL. Three weeks following discharge, creatinine levels were 1.5 mg/dL with decreased proteinuria. Discussion(s): Collapsing FSGS in immunocompetent patients is uncommon. Reports mention benefits of ganciclovir and steroid therapy for CMV infection in immunocompromised patients. CMV infection should be considered in patients with systemic inflammatory disease and severe renal failure, as early treatment with steroids and antivirals helps preserve renal function.

Background: The severe acute respiratory syndrome coronavirus-2 (SARSCoV-2) was first reported in Wuhan, China in December2019 and represented the pathogen agent that induced COVID-19. The onset and evolution of COVID -19 is severe when is associated with another comorbidities. Patients with acute leukemia present high risk for severe form of COVID-19 Aims: The main objective was to evaluate the particularities of COVID-19 in patients with acute leukemia. Methods: Our study was prospective and included 49 patients with acute leukemia (27 male median age 64 and22 female median age 54,5) who also were SARS CoV2 positive between April2020- February2021 admitted in Hematology and Intensive Care Unit Departments of Colentina Clinical Hospital Bucharest. The diagnosis was established using molecular test for SARS-Cov2 Results: In the group was included 32 patients diagnosed with acute myeloid leukemia (AML), 9 patients with acute lymphoid leukemia (ALL), 6 patients with acut promyelocytic leukemia and2 patients with acute bifenotypic leukemia. Severe form of COVID-19 with ICU addmission was diagnosed in16 patients (32,17%), almost all of them (15 patients) had unfavourable evolution compared with non-ICU patients group with only1 deceased patient, p<0.0001. The recent chemotherapy followed by severe aplasia was the main negative factor that impacted patient evolution (rho=0.508, p=0.0002),13 patients admitted in ICU Department and12 patients in non-ICU. Severe pneumonia (more than 30% lung field) was diagnosed in17 patients with recent chemotherapy and 4 untreated patients. The type of leukemia or refractory status have not any impact of patient evolution. Antiviral therapy - Remdesivir rapidly introduced in patient's therapy was followed by favourable evolution. Summary/Conclusion: Patients with acute leukemia are negatively impacted by intensive chemotherapy during COVID-19 evolution. The key for good prognosis of these patients during COVID-19 are rapid diagnosis and antiviral therapy at the onset of the disease.
