RESUMEN

INTRODUCTION: During the height of the coronavirus disease-19 (COVID-19) pandemic, some renal replacement therapy (RRT) modalities were insufficient, forcing medical centers to diversify the RRT modalities offered. In this study, we reported the outcomes of chronic peritoneal dialysis (PD) patients and acute PD in critically ill patients during COVID-19 pandemic in a tertiary care medical center in Mexico. METHODS: This descriptive, longitudinal, observational, retrospective study included 47 adult patients with atypical pneumonia in a tertiary care medical center in Mexico during the first and second waves of the COVID-19 pandemic. Chronic PD patients and PD incident patients due to acute kidney injury (AKI) were included. RESULTS: Forty-seven patients were studied (29 chronic PD patients and 18 incident PD patients due to AKI); median age was 59 (48-68) years; 63.8% were men. The ultrafiltrate volume per day was 815 (596.1-1,193.2) mL. Overall mortality was 61.7%, 55.2% in chronic PD patients, and 72.2% in PD incident patients due to AKI. A higher Sequential Organ Failure Assessment (SOFA) score, the need for mechanical ventilation at admission, and the requirement for vasopressors were predictors for mortality (p < 0.01). CONCLUSION: In low- and lower-middle-income countries, PD was a valid alternative for RRT during the COVID-19 pandemic. In AKI patients, PD can correct hyperkalemia, acidosis, uremia, and volume overload; however, there was higher mortality in PD incident patients due to AKI. The main risk factors for mortality were a high SOFA score at admission, the need for invasive mechanical ventilation, and the requirement for vasopressors.

RESUMEN

The relationship between focal segmental glomerulosclerosis (FSGS) and pregnancy is complex and not completely elucidated. Pregnancy in patients with FSGS poses a high risk for complications, possibly due to hemodynamic factors, imbalance between angiogenic and antiangiogenic factors, and hormonal conditioning. Although poor clinical outcomes associated with collapsing FSGS are common outside of pregnancy, the prognosis during pregnancy is not well documented. We report 3 patients who developed collapsing FSGS during pregnancy, 2 of whom had presumed underlying FSGS. Two patients underwent biopsy during pregnancy, and 1, during the puerperium. None of the 3 patients improved spontaneously after delivery, and 1 experienced a rapid deterioration in kidney function and proteinuria after delivery. Aggressive immunosuppressive therapy led to a full response in 1 case (without chronic lesions) and to partial responses in the remaining 2 cases. These cases suggest that collapsing lesions should be considered in patients with FSGS who develop a rapid increase in serum creatinine level or proteinuria during pregnancy and that these lesions may at least partially respond to treatment.

RESUMEN

Chronic kidney disease (CKD) is increasingly recognized as a risk factor in pregnancy; the differential diagnosis between CKD and preeclampsia (PE) may be of pivotal importance for pregnancy management and for early treatment of CKD. Acknowledging this connection may be useful also in a wider context, such as in the case reported in this paper, which for the first time describes an association between syphilis infection and IgA-dominant glomerulonephritis. A 16-year-old woman, referred to a general hospital due to a seizure, was found to be unknowingly pregnant. Based on hypertension and nephrotic proteinuria, she was initially diagnosed with PE. Immunological tests, as well as hepatitis and HIV tests showed negative results. However, secondary syphilis was diagnosed. In discordance with the PE diagnosis, urinalysis showed glomerular microhematuria with cellular casts. Proteinuria and hypertension did not remit after delivery, which was made via caesarean section, due to uncontrolled hypertension, at an estimated gestational age of 29 weeks. A male baby, weighing 1.1 kg (6.5 centile) was born. The baby was hospitalized in the neonatal intensive care unit, where he developed subependymal hemorrhage and thrombocytopenia, and neonatal syphilis was diagnosed. The mother underwent a kidney biopsy one week after delivery, leading to the diagnosis of IgA-dominant postinfectious glomerulonephritis. Mother and child were treated with support and antibiotic therapy, and were discharged in good clinical conditions four weeks later. Four months after delivery, the mother was normotensive without therapy, with normal kidney function and without hematuria or proteinuria. In conclusion, this case suggests that IgA-dominant postinfectious glomerulonephritis should be added to the spectrum of syphilis-associated glomerulonephritides, and underlines the need for a careful differential diagnosis with CKD in all cases of presumed PE. While diagnosis relies on kidney biopsy, urinary sediment, a simple and inexpensive test, can be the first step in distinguishing PE from other nephropathies.
