Bilateral Emphysematous Pyelonephritis Associated with COVID Pneumonia: A Case Report.

BACKGROUND 0ptviral pneumonia and bilateral emphysematous pyelonephritis create a rapid acute respiratory distress syndrome. CASE REPORT A 59-year-old diabetic man with altered awareness was admitted as an emergency due to fever, shivering, and pain in the lap. Based on the accurate diagnosis, we concluded that the patient had bilateral emphysematous pyelonephritis, as well as inflammatory changes in the lung parenchyma caused by coronavirus infection (SARS-CoV-2). Active therapy - nephrectomy - was ruled out due to the late detection of the gas collection in the kidneys, as well as the general condition caused by respiratory symptoms. With symptomatic, supportive, and antimicrobial therapy, such as percutaneous renal drainage, renal abnormalities improved. Unfortunately, the virus-induced parenchymal inflammation progressed and proved fatal. The inflammatory process in the urothelial cell is most likely where the linkage and potentiation of COVID-19 infection and emphysematous pyelonephritis begins. Local inflammation that obstructs the movement of the generated gas is one of the hypothesized processes of emphysematous pyelonephritis. The renal and urothelial tubular cells contain the angiotensin-converting enzyme II (ACE2) receptor, which is used by the SARS-CoV-2 virus to enter human cells and may be a risk factor for simultaneous and direct viral injury to urinary tract cells. Sepsis was most likely caused by viral pneumonia, based on the resolution of changes in the kidneys. CONCLUSIONS The combination of EPN and COVID-19 is difficult to treat. Despite multidisciplinary treatment, it has been linked to a worse prognosis and fatal outcome.

Emphysematous cystitis with bilateral pyelonephritis in a pediatric patient with COVID-19.

A 15-year-old female adolescent with a medical history of recurrent urinary tract infections and grade 1 left-sided vesicoureteral reflux presented to the emergency room with abdominal and back pain. Labs revealed a haemoglobin A1c (HbA1c) of 9.1% and a random blood glucose of 200 mg/dL, consistent with new-onset diabetes mellitus. Nasopharyngeal COVID-19 PCR test returned positive. A CT scan of the abdomen and pelvis revealed bilateral attenuation of the kidneys and air in the bladder, which was confirmed by pelvic ultrasound. Gas subsequently resolved 2 days later after treatment with antibiotics, and a diagnosis of emphysematous cystitis was made. Emphysematous cystitis in the paediatric population is an extremely rare condition with four cases reported in the literature. Furthermore, there has been a reported association between COVID-19, cystitis and non-typical course of urinary symptoms. Local inflammation obstructing transportation of formed gas is one of the proposed mechanisms underlying emphysematous cystitis, and so COVID-19 may be yet another predisposing factor.

Fatal allograft mucormycosis complicating severe COVID-19 infection and bacterial pyelonephritis.

We herein present a case of live related kidney transplant recipient who initially developed severe coronavirus (COVID-19) disease associated with E.coli related pyelonephritis and graft dysfunction, who improved over one week only to deteriorate in the second week, with fever, oligoanuria and refractory shock. A postmortem allograft biopsy revealed angioinvasive mucormycosis. With the resurgence of mucormycosis during the COVID-19 pandemic, the transplant team should add allograft mucormycosis as a rare differential for severe graft dysfunction and oligoanuria in the COVID-19-infected kidney transplant recipient.

COVID-19 Pandemic and Pregnancy in Kidney Disease.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is a rapidly spreading pandemic. Owing to changes in the immune system and respiratory physiology, pregnant women are vulnerable to severe viral pneumonia. We review the clinical course, pregnancy outcomes, and management of women with COVID-19 in pregnancy with a focus on those with kidney involvement. Current evidence does not show an increased risk of acquiring SARS-CoV-2 during pregnancy and the maternal course appears to be similar to nonpregnant patients. However, severe maternal disease can lead to complex management challenges and has shown to be associated with higher incidence of preterm and caesarean births. The risk of congenital infection with SARS-CoV-2 is not known. All neonates must be considered as high-risk contacts and should be screened at birth and isolated. Pregnant women should follow all measures to prevent SARS-CoV-2 exposure and this fear should not compromise antenatal care. Use of telemedicine, videoconferencing, and noninvasive fetal and maternal home monitoring devices should be encouraged. High-risk pregnant patients with comorbidities and COVID-19 require hospitalization and close monitoring. Pregnant women with COVID-19 and kidney disease are a high-risk group and should be managed by a multidisciplinary team approach including a nephrologist and neonatologist.
