Hydroxychloroquine-Induced Phospholipidosis - A Forgotten Complication of a Common Drug

Hydroxychloroquine (HCQ) has immunomodulatory and immunosuppressive properties and is used in many rheumatological conditions like systemic lupus erythematosus, rheumatoid arthritis, and Sjogren's syndrome. It is usually a widely used and well-tolerated DMARD (Disease Modifying Anti Rheumatic Drugs). Its most feared toxicities include retinopathy and, rarely, cardiomyopathy. Among its other reported side effects is drug-induced phospholipidosis. Here, we report two cases of HCQ-induced phospholipidosis based on renal biopsy electron microscopy. HCQ-induced phospholipidosis, although uncommon, must be considered as one of the differentials in a patient with persistent proteinuria.

Advances in Takayasu arteritis: An Asia Pacific perspective

Takayasu Arteritis (TA) is a rare form of chronic granulomatous large vessel vasculitis that is more common in Asia compared to other parts of the world. There have been several developments in the field of Takayasu arteritis in relation to genetics, classification, clinical features, imaging, disease activity assessment and management and much of these works have been done in the Asia Pacific region. We will be discussing selected few in the current review.

Update on pregnancy in Takayasu arteritis-A narrative review

Takayasu arteritis (TA) is a chronic, idiopathic large-vessel vasculitis that affects women of reproductive age, and has significant maternal and fetal implications. Although there are contrasting data on the effect of TA on fertility, most studies have shown that fertility outcomes remain unaffected. The disease activity of TA usually either remains stable or decreases during pregnancy. The important fetomaternal complications are maternal hypertension, pre-eclampsia, prematurity, and intrauterine growth restriction. To reduce maternal and fetal morbidity, controlling the disease before conception is important. This review article discusses the various implications, challenges, and medical and endovascular management of TA during pregnancy.
