BACKGROUND: Patients with autosomal dominant polycystic kidney disease (ADPKD) may require specific therapy with vasopressin receptor antagonists to slow the progression of renal disease. Because of its mechanism of action, the most common side effects are polyuria, nocturia, and polydipsia. Elevations of liver enzyme levels can also occur during treatment with Tolvaptan. Temporary drug withdrawal may be indicated if the patient is unable to hydrate adequately or if there are concomitant causes of dehydration, including major infectious events. During the Coronavirus Disease 2019 (COVID-19) pandemic, this should be considered in the management of patients on Tolvaptan therapy. CASE REPORT: We present the clinical case of a 51-year-old male with severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2) infection and ADPKD receiving Tolvaptan therapy with particular reference to the medical management of the patient during the infectious event. The patient was instructed to discontinue promptly Tolvaptan as soon as symptoms appeared. He was treated with forced hydration and symptomatic therapy. Nevertheless, a transient elevation of liver enzyme levels was detected. The timely discontinuation of Tolvaptan therapy avoided the risk of potential hepatotoxicity in a condition of known susceptibility. CONCLUSION: Tolvaptan therapy of patients with ADPKD is safe even during SARS-CoV-2 infection. There is need for appropriate and prompt patient counseling to avoid potentially adverse side effects.

The novel coronavirus, called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was declared a pandemic in March 2020 by the World Health Organization. Older individuals and patients with comorbid conditions such as hypertension, heart disease, diabetes, lung disease, chronic kidney disease (CKD) and immunologic diseases are at higher risk of contracting this severe infection. In particular, patients with advanced CKD constitute a vulnerable population and a challenge in the prevention and control of the disease. Home-based renal replacement therapies offer an opportunity to manage patients remotely, thus reducing the likelihood of infection due to direct human interaction. Patients are seen less frequently, limiting the close interaction between patients and healthcare workers who may contract and spread the disease. However, while home dialysis is a reasonable choice at this time due to the advantage of isolation of patients, measures must be assured to implement the program. Despite its logistical benefits, outpatient haemodialysis also presents certain challenges during times of crises such as the coronavirus disease 2019 (COVID-19) pandemic and potentially future ones.
