Hematologic malignancy, particularly lymphoma, is not uncommon in ITG. ITG appears to have a better prognosis than other paraprotein-related renal lesions, with a half of patients expected to recover kidney function with immunosuppressive therapy or chemotherapy. The proteomic profile of ITG is consistent with deposition of monotypic immunoglobulins and activation of the classical and terminal pathway of complement.

This study represents one of the largest characterizations of stone composition in the Middle East. There remains a significant gender disparity in stone prevalence in the Eastern Province of KSA, with males affected to a significantly greater extent. Calcium oxalate is the most common type of stone, and this is true for both men and women. Future investigations of dietary and environmental factors can build on these initial epidemiologic findings.

Objectives: To report the outcome of patients with end stage kidney disease (ESKD) who were diagnosed with COVID-19 at a large community hospital in Eastern Saudi Arabia.Methods: A single center, prospective observational study at Johns Hopkins Aramco Healthcare, Dhahran, Saudi Arabia. Patients with ESKD who were maintained on dialysis and developed COVID-19 between June 15, 2020 and October 31, 2021 were enrolled. Results:In total, 30 patients with ESKD were diagnosed with severe acute respiratory syndrome coronavirus 2 infection. Twenty two (73%) patients developed the disease prior to COVID-19 vaccine rollout. The median age of the cohort was 63 (55-75) years. Most patients were diabetic (73%), hypertensive (97%) and had a median body mass index of 28 kg/m 2 . Twenty seven (90%) patients required admission, 16 (52%) patients developed pneumonia, and 5 (17%) patients required mechanical ventilation. Patients who developed pneumonia were older, and the majority had diabetes mellitus and coronary artery disease. Five patients died with a total mortality of 17%. Conclusion:Patients with ESKD who developed COVID-19 had a poor outcome with high mortality compared to the general population. Presence of diabetes mellitus, coronary artery disease and older age were associated with a higher risk of severe disease. There was a sharp decline in the number of positive cases following implementation of the vaccination program.

We report a case of benign recurrent intrahepatic cholestasis (BRIC) in an 11-year-old Saudi girl who developed three episodes of pruritus and jaundice at the ages of 4, 8, and 9 years. These episodes were almost stereotypic and lasted 5-8 weeks. Although she had elevated liver enzymes and serum bile acids in her blood during the attacks, they returned to normal between attacks. Thorough investigation excluded other causes of liver disease and her recurrent attacks were shortened by cholestyramine therapy. A diagnosis of BRIC should be kept in mind in patients with cholestasis.
