Long-Term Follow up of Renal and Other Acute Organ Failure in Survivors of Critical Illness Due to Covid-19.

BACKGROUND: Little is known about the long-term health sequelae and outcomes of various organ failures in ICU survivors of Covid-19. The aim of our research was to study the characteristics of 120-day ICU survivors of the initial pandemic surge and report their long term (>6 months) outcomes. METHODS: We conducted a telephone questionnaire-based follow up study of 120- day survivors of Covid-19 admitted to ICUs at Montefiore Medical Center, Bronx, NY from 3/10/2020 to 4/11/2020. The study period was 2 months (11/1/2020-12/31/2020). RESULTS: 126 out of 300 (42%) survived to 120-days post-hospital discharge. The median age of survivors was 54 (47-61) years. Seventy-eight (62%) patients developed acute kidney injury (AKI); thirty-five (44.9%) of them required renal replacement therapy (RRT). One hundred-five (83.3%) required invasive mechanical ventilation; ten of them required tracheotomy. 103 (81.7%) completed the telephone questionnaire-based study, at a median (IQR) of 216.5 (200-234.5) days after hospital discharge. 29 (28.2%) patients reported persistent shortness of breath, 24, (23.3%) complained of persistent cough, and persistent anosmia in 9 (8.8%). AKI resolved completely in 58 (74.4%) patients. Of 35 AKI patients who required initiation of RRT during hospitalization, 27 (77%) were liberated from RRT and 20 (57%) had resolution of AKI. Of 20 patients without AKI resolution, 12 developed chronic kidney disease, whereas 8 still require RRT. Thirty-three (32.4%) patients developed post-traumatic stress disorder (PTSD) and 10 (11.8%) reported major depression. Many of the patients (68%) regained baseline functional status. Readmissions occurred in 22.3% patients within first 6 months after discharge. CONCLUSION: Persistent symptoms of long Covid have been reported in ICU survivors of Covid-19 for extended durations. Outcomes of Covid-19 associated acute kidney injury are excellent. There is a high incidence of PTSD and depression in COVID-19 ICU survivors. Functional outcomes are good, but these patients remain at increased risk of hospital readmission.

The changing epidemiology of acute kidney injury syndromes in the face of emerging respiratory viral pandemic illnesses.

In this issue, Birkelo et al. performed a rigorous analysis of acute kidney injury (AKI) differences in patients hospitalized with coronavirus disease 2019 versus influenza. Coronavirus disease 2019 AKI was more severe, with worse outcomes, than influenza, despite adjustment for confounders. Their findings highlight the need for development of a new category of AKI syndrome, "viral pandemic-associated AKI," in which a more varied pathophysiological approach to AKI would combine with consideration of overcoming future surge-related resource shortages.

Learn to Live Again.

The COVID-19 pandemic has claimed more than 4.5 million lives so far throughout the world. These sudden, unnatural, and unexpected deaths have led to complicated grief reactions as families did not get time to prepare for death. I describe the experience of my family in India during the disastrous second wave of the pandemic. The experience of many such families of COVID-19 casualties is like a horror story that will continue to scare them each day of their life. These families have already suffered a serious and long-lasting harm and are at greater risk of suffering from prolonged grief disorder, post-traumatic stress disorder, depression, emotional distress, adult separation disorder, and generalized anxiety disorder for a long period of time. Creating support groups, empowering primary-care physicians to help and counsel their patients, providing them access to cognitive behavioral therapy, help with opening up and venting out some of their feelings, and training to develop resilience are some of the measures to help our grieving patients.

Anemia Management in the Cancer Patient With CKD and End-Stage Kidney Disease.

Anemia is a common medical problem among patients with cancer and chronic kidney disease (CKD). Although anemia in patients with CKD is often treated with iron and erythropoietin-stimulating agents, there are controversies with regard to the use of erythropoietin-stimulating agents in cancer patients. In this article, we review the treatment of anemia in patients with cancer and CKD, in addition to summarizing the current guidelines in treatment of anemia in these patients.

Associations of Dysnatremia with COVID-19 Status and Mortality.

Background: In patients without COVID-19, dysnatremia is associated with mortality. These relationships are not well established in patients with COVID-19. We tested the hypotheses that patients with COVID-19 were more likely to have dysnatremia than those without COVID-19 and that, among those with COVID-19, dysnatremia is associated with mortality. Methods: We conducted a retrospective observational study of patients admitted to a tertiary care center in the Bronx, New York, during the COVID-19 surge from March 11 to April 26, 2020. Using multinomial logistic regression models, we compared the prevalence of hypernatremia (serum sodium ≥150 mEq/L) and hyponatremia (serum sodium <130 mEq/L) on admission between patients with and without COVID-19. Among patients with COVID-19, we used Cox proportional hazards models to examine the association of dysnatremia with mortality. Results: Compared with those without COVID-19 (n=1265), patients with COVID-19 (n=3345) had a higher prevalence of hypernatremia (7% versus 4%, P<0.001) and hyponatremia (7% versus 6%, P=0.04). In adjusted models, COVID-19-positive patients had a higher likelihood of having hypernatremia (adjusted odds ratio=1.87, 95% CI, 1.3 to 2.57, P=0.001) compared with COVID-19-negative patients, whereas the association between hyponatremia and COVID-19 status was no longer significant (P=0.06). Among patients with COVID-19, 775 (23%) died after a median follow-up of 17 days (IQR 7-27 days). Among nonsurvivors, 15% had hypernatremia and 8% had hyponatremia on admission. Hypernatremia was associated with a higher risk of mortality (adjusted hazard ratio=1.28, 95% CI, 1.01 to 1.63, P=0.04) compared with patients with eunatremia. Conclusions: In patients hospitalized during the spring 2020 COVID-19 surge, COVID-19 status was associated with hypernatremia on admission. Among patients with COVID-19, hypernatremia was associated with higher mortality. Hypernatremia may be a potential prognostic marker for mortality in COVID-19 patients.

Characteristics, Outcomes and 60-Day Hospital Mortality of ICU Patients with COVID-19 and Acute Kidney Injury.

Background: AKI has been reported in patients with COVID-19 pneumonia and it is associated with higher mortality. The aim of our study is to describe characteristics, outcomes, and 60-day hospital mortality of patients with COVID-19 pneumonia and AKI in the intensive care unit (ICU). Methods: We conducted a retrospective study in which all adult patients with confirmed COVID-19 who were admitted to ICUs of Montefiore Medical Center and developing AKI were included. The study period ranged from March 10 to April 11, 2020. The 60-day follow-up data through June 11, 2020 were obtained. Results: Of 300 adults admitted to the ICUs with COVID-19 pneumonia, 224 patients (75%) presented with AKI or developed AKI subsequent to admission. A total of 218 (97%) patients required invasive mechanical ventilation for moderate to severe acute respiratory distress syndrome (ARDS). A total of 113 (50%) patients had AKI on day 1 of ICU admission. The peak AKI stages observed were stage 1 in 49 (22%), stage 2 in 35 (16%), and stage 3 in 140 (63%) patients, respectively. Among patients with AKI, 114 patients (51%) required RRT. The mortality rate of patients requiring RRT was 70%. Of the 34 patients who were survivors, 25 (74%) were able to be weaned off RRT completely before hospital discharge. Nonsurvivors were older and had significantly higher admission and peak creatinine levels, admission hemoglobin, and peak phosphate levels compared with survivors. The 60-day hospital mortality was 67%. Conclusions: COVID-19 requiring ICU admission is associated with high incidence of severe AKI, necessitating RRT in approximately half of such patients. The majority of patients with COVID-19 and AKI in ICU developed moderate to severe ARDS, requiring invasive mechanical ventilation. Timing or severity of AKI did not affect outcomes. The 60-day hospital mortality is high (67%). Patients with AKI requiring RRT have high mortality, but survivors have good rates of RRT recovery.

Septic pulmonary emboli causing recurrent bilateral pneumothoraces in a patient with right sided endocarditis: A case report and review of literature.

Patients with a history of drug abuse and right sided endocarditis are prone to develop septic pulmonary emboli. Pneumothorax is a rare complication of septic pulmonary emboli reported in the literature, likely due to the rupture of thin-walled septic cavitary lesions resembling pneumatoceles into the pleural space. Only seven cases (including our case) of pneumothorax from septic pulmonary emboli due to right sided endocarditis have been described in the literature. Our patient is the first reported case of recurrent bilateral pneumothorax due to septic pulmonary emboli and tricuspid valve endocarditis.

Pregnancy outcomes in women on hemodialysis: a national survey.

Background. Pregnancy occurs among 1-7% of women on chronic dialysis. Experience regarding pregnancy and dialysis originates from anecdotal reports, case series and surveys. This survey updates the US nephrologists' experience with pregnancy on hemodialysis (HD) over the past 5 years. We evaluated maternal and fetal outcomes, certain practice patterns such as dialysis regimens utilized and nephrologist knowledge and comfort level when caring for a pregnant patient on HD. Methods. An anonymous Internet-based 23-question survey was e-mailed to end-stage renal disease Networks of America program directors for forwarding to practicing nephrologists. Results. A total of 196 nephrologists responded to the survey, reporting >187 pregnancies. Of the respondents, 45% had cared for pregnant females on HD and 78% of pregnancies resulted in live births. In 44% of the pregnancies a diagnosis of preeclampsia was made. There were no maternal deaths. Nephrologists most commonly prescribe 4-4.5 h of HD 6 days/week for pregnant women on dialysis. Women dialyzed cumulatively for >20 h/week were 2.2 times more likely to develop preeclampsia than those who received ≤20 h of HD per week. Conclusion. Providing intensive HD is a common treatment approach when dialyzing pregnant women. Maternal and fetal outcomes can be improved. There is a trend toward better live birthrates with more intense HD. Whether more cumulative hours of dialysis per week increases the risk of preeclampsia needs to be further investigated.

Theophylline toxicity leading to suicidal ideation in a patient with no prior psychiatric illness.

Suicidal behavior is a common psychiatric emergency and is associated with psychiatric illness and history of prior suicide attempts. Neuropsychiatric manifestations related to theophylline toxicity are well described in literature. We report a case of theophylline toxicity manifesting as suicidal ideation in a patient with no prior psychiatric illness.

Onconephrology abstracts and publication trends: time to collaborate.

Onconephrology is an emerging subspecialty of nephrology. The American Society of Nephrology(ASN) created a forum dedicated to the field of onconephrology in 2011 to improve collaborative care for cancer patients with kidney disease. In this article, we review the ASN Kidney Week abstracts that were related to onconephrology. There has been an increase in the number of onconephrology-related abstracts at ASN over last 3 years. But only one-fifth of abstracts that were onconephrology related in ASN were published in peer review journals. Clinical Kidney Journal (CKJ) has seen an increase in onconephrology publications in the last 3 years. Most were case reports or review articles. The more widespread use of the keyword 'onconephrology' in all such manuscripts may facilitate the search for onconephrology research papers. To advance the field, CKJ has now created an onconephrology subheading for manuscript categorization. We also propose that conference organizers of ASN and other kidney-related society meeting such as International Society of Nephrology, National Kidney Foundation and European Dialysis and Transplantation Association have a separate onconephrology abstract category. Randomized controlled trials in a subspecialty like onconephrology can only be possible when there is collaboration amongst nephrologists and cancer physicians from cancer centers around the world that interact and share research ideas at international meetings.
