More difficult still: Treating severe rapidly progressive glomerulonephritis in the context of COVID-19 pneumonia. / Más difícil todavía: tratar una glomerulonefritis rápidamente progresiva grave en el seno de una neumonía por COVID-19.

We present the case of a male patient with severe SARS-CoV-2 pneumonia, with simultaneous onset of p-ANCA positive rapidly progressive glomerulonephritis. We discuss the different therapeutic possibilities, emphasising the appropriateness of their administration according to the time in the course of the infection.

Systemic thrombosis in a large cohort of COVID-19 patients despite thromboprophylaxis: A retrospective study.

BACKGROUND: Incidence of thrombotic events associated to Coronavirus disease-2019 (COVID-19) is difficult to assess and reported rates differ significantly. Optimal thromboprophylaxis is unclear. OBJECTIVES: We aimed to analyze the characteristics of patients with a confirmed thrombotic complication including inflammatory and hemostatic parameters, compare patients affected by arterial vs venous events and examine differences between survivors and non-survivors. We reviewed compliance with thromboprophylaxis and explored how the implementation of a severity-adjusted protocol could have influenced outcome. METHODS: Single-cohort retrospective study of COVID-19 patients admitted, from March 3 to May 3 2020, to the Infanta Leonor University Hospital in Madrid, epicenter of the Spanish outbreak. RESULTS: Among 1127 patients, 80 thrombotic events were diagnosed in 69 patients (6.1% of the entire cohort). Forty-three patients (62%) suffered venous thromboembolism, 18 (26%) arterial episodes and 6 (9%) concurrent venous and arterial thrombosis. Most patients (90%) with a confirmed thrombotic complication where under low-molecular-weight heparin treatment. Overt disseminated intravascular coagulation (DIC) was rare. Initial ISTH DIC score and pre-event CRP were significantly higher among non-survivors. In multivariate analysis, arterial localization was an independent predictor of mortality (OR = 18, 95% CI: 2.4-142, p < .05). CONCLUSIONS: Despite quasi-universal thromboprophylaxis, COVID-19 lead to a myriad of arterial and venous thrombotic events. Considering the subgroup of patients with thrombotic episodes, arterial events appeared earlier in the course of disease and conferred very poor prognosis, and an ISTH DIC score ≥ 3 at presentation was identified as a potential predictor of mortality. Severity-adjusted thromboprophylaxis seemed to decrease the number of events and could have influenced mortality. Randomized controlled trials are eagerly awaited.

Immunosuppression as a trigger for hyperinflammatory syndrome due to Strongyloides stercolaris in membranous nephropathy. / Inmunosupresión como desencadenante de un síndrome de hiperinfestación por Strongyloides stercolaris en la nefropatía membranosa.

The relationship between parasites and glomerulonephritis (GN) is well documented in certain parasitoses, but not in cases of Strongyloides stercolaris (S. stercolaris) where there are few cases described being the majority GN of minimal changes. We report a case of hyperinfestation by S. stercolaris in a patient affected by a membranous GN treated with oral corticosteroids with fatal outcome for the patient. This case provides a double teaching: first about a rare association of strongyloid and membranous GN and second about the importance of establishing a diagnosis of suspected and appropriate treatment for certain infections or diseases with little clinical expression before starting any immunosuppressive treatment.
