COVID-19 and APOL-1 High-Risk Genotype-Associated Collapsing Glomerulonephritis.

Coronavirus Disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) primarily affects the lungs and can lead to acute respiratory distress syndrome (ARDS). The ongoing global pandemic has created healthcare and economic crisis for almost every nation of the world. Though primarily affecting the lungs, it has also affected the kidney in various ways including acute kidney injury (AKI), proteinuria, and hematuria.

Pembrolizumab related Guillain barre syndrome, a rare presentation in a patient with a history of lupus and bladder cancer.

Immune checkpoint inhibitor-related neurotoxicity causing Guillain Barre Syndrome is relatively uncommon. We discussed an 80-year-old patient with known systemic lupus erythematosus who presented with lower extremity weakness, areflexia and then progressed to respiratory muscle and upper extremity weakness after receiving immunotherapy with checkpoint inhibitors for metastatic bladder cancer. With the increasing use of immunotherapy for the management of cancer, awareness of neurological autoimmune side effects is essential.

A case of neuromyelitis optica spectrum disorder with coexisting systemic lupus erythematosus.

Neuromyelitis Optica or Devic disease is changed to Neuromyelitis Optica spectrum disorder to include more diverse neurological and autoimmune manifestations. This is a severe relapsing autoimmune demyelinating disorder commonly affecting the optic nerve and spinal cord. It has been reported as either the first manifestation of SLE or as a coexisting condition with other autoimmune disorders commonly included but not limited to SLE and SS.

Fat Embolism Syndrome in Sickle Cell β-Thalassemia Patient With Osteonecrosis: An Uncommon Presentation in a Young Adult.

Fat embolism syndrome is a relatively infrequent presentation in sickle cell thalassemia patients. It most commonly occurs in long bone fractures in the setting of trauma. However, nonorthopedic trauma and nontraumatic cases have been reported to contribute to fat embolism.

Paget-Schroetter Syndrome in a Young Female.

Paget-Schroetter syndrome or effort thrombosis is a relatively rare primary spontaneous thrombosis of upper extremity deep veins secondary to entrapment of axillary subclavian veins from an abnormality of the thoracic outlet. It is commonly seen in young adults who lift heavy weights or strenuous use of the upper extremities during athletic activities. Repetitive microtrauma to the subclavian vein secondary to narrow costoclavicular space and strenuous activities leads to intimal layer inflammation, hypertrophy, fibrosis, and coagulation cascade activation.

Bacteremia Secondary to Uncommon Gram-Negative Bacilli Transmitted From the Canine in a Patient With Multiple Myeloma.

Back to basics: review on vitamin D and respiratory viral infections including COVID-19.

Importance: As the scientific community is in a marathon in finding out the cure for COVID-19, in this crisis, it is essential for the physicians not to forget about the basics. Due to the pandemic crisis, in many nursing homes and hospitals, there established new policies on decreasing unnecessary medications to minimize cross-contamination. Sometimes these policies are making providers avoid essential drugs such as Vitamins, including Vitamin D.

Outcomes of in Patients with Vitamin D Deficiency: A Propensity-Matched National Inpatient Sample Analysis.

Objectives: We aimed to determine in-hospital outcomes, length of hospital stay, and resource utilization in a contemporary cohort of infection (CDI) and vitamin D deficiency (VDD).

Methods: The National Inpatient Sample database for 2016 and 2017 was used for data analysis using () codes to identify the patients with the principal diagnosis of CDI and VDD. We assessed the all-cause in-hospital mortality, morbidity, length of hospital stay (LOS), and total costs between propensity-matched groups of CDI without VDD versus CDI with VDD.

COVID-19 in Renal Transplant Patient Presenting With Active Typical Symptoms and Resolved Atypical Symptoms.

The novel coronavirus disease has brought the world to standstill with high infectivity and rapid transmission. The disease caused by novel coronavirus is termed as coronavirus disease 2019 (COVID-19). We present the case of a renal transplant patient who was infected with COVID-19 through community spread and presented with fever and gastrointestinal symptoms.

Potential Zoonotic Origins of SARS-CoV-2 and Insights for Preventing Future Pandemics Through One Health Approach.

Coronavirus disease 2019 (COVID-19) is an emerging infectious disease that has resulted in a global pandemic and is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Zoonotic diseases are infections that are transmitted from animals to humans. COVID-19 caused by SARS-CoV-2 most likely originated in bats and transmitted to humans through a possible intermediate host.

Cannabis Vaping-Induced Acute Pulmonary Toxicity: Case Series and Review of Literature.

The use of cannabis for recreational as well as medicinal use is on the rise recently with more states legalizing it. We conducted a review analysis of the literature published on acute respiratory failure from vaping cannabis oil. We have also summarized the clinical details (age, length of stay, mode of ventilation, common clinical findings, and steroid use) along with common laboratory abnormalities.

Gastrointestinal Manifestations in COVID-19 Infection and Its Practical Applications.

The latest novel coronavirus (COVID-19) outbreak, which emerged in December 2019 in Wuhan, Hubei, China, is a significant cause of the pandemic. This outbreak is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and is also commonly known as COVID-19. A typical symptom includes cough and fever, but a considerable number of patients can manifest gastrointestinal (GI) symptoms, including diarrhea, which can be the initial presentations and may or may not present with respiratory symptoms or fever.

Case Report: Dilated cardiomyopathy with biventricular thrombus secondary to impaired coagulation in a patient with HIV.

Human immunodeficiency virus (HIV) infection is a known hypercoagulable state with venous thromboembolism with a high mortality rate compared to the general population. The homeostatic balance in HIV infected patients improves with treatment compared to those who are not.  A decreased hypercoagulable state noted by low levels of Von Willebrand factor, factor VIII and d-dimer levels along with higher protein C and S activity in patients on treatment suggests that hypercoagulable state is partially correctable with highly active antiretroviral therapy.

Acute Kidney Injury in a Case Series of Patients with Confirmed COVID-19 (Coronavirus Disease 2019): Role of Angiotensin-Converting Enzyme 2 and Renin-Angiotensin System Blockade.

The renin-angiotensin system plays a very critical role in hypertension, diabetes, and kidney and heart diseases. The blockade of the renin-angiotensin system results in the prevention of progression of renal and cardiac damage. There have been controversial hypotheses raised regarding the safety of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers in COVID-19 (coronavirus disease 2019).

Cocaine and Alcohol Co-Ingestion-Induced Severe Rhabdomyolysis With Acute Kidney Injury Culminating in Hemodialysis-Dependent End-Stage Renal Disease: A Case Report and Literature Review.

Cocaine toxicity is associated with several organ dysfunctions, including acute kidney injury (AKI). Rhabdomyolysis is the most likely mechanism that mediates AKI, and associated alcohol co-ingestion can amplify the situation. AKI, if severe, can result in end-stage renal disease (ESRD) requiring renal replacement therapy (RRT).

Use of Immunotherapy in Extensive-Stage Small Cell Lung Cancer.

Lung cancer is a leading cause of cancer death in the United States and around the world. Approximately 13% of lung cancers are small cell lung cancer (SCLC). SCLC is generally classified as a limited-stage and extensive-stage disease depending on the extent of involvement.

The purpose of this review is to analyze the impact of the virus on the kidney.

Medical Management of COVID-19: Evidence and Experience.

Coronavirus disease 2019 is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and this infectious disease is termed COVID-19 in short. On a global scale, as of June 1, 2020, the World Health Organization (WHO) published statistics of 6,057,853 infected patients and 371,166 deaths worldwide. Despite reported observational data about the experimental use of certain drugs, there is no conclusively proven curative therapy for COVID-19 as of now; however, remdesivir received emergency use authorization (EUA) by the Food and Drug Administration (FDA) recently for use in patients hospitalized with COVID-19.

Coronavirus Disease 2019 (COVID-19) in a Renal Transplant Patient.

Coronavirus disease 2019 (COVID-19) has resulted in significant morbidity and mortality worldwide. Transplant patients are particularly at a higher risk of contracting COVID-19 because of their immunosuppressed state, and they have the propensity to develop opportunistic infections. The pre-immunosuppressed state, along with other existing comorbidities, can influence the outcomes of COVID-19 in transplant patients.
