RESUMO
This case report details a rare presentation of diffuse scleroderma, where a 38-year-old female developed hypertensive encephalopathy due to scleroderma renal crisis (SRC). SRC, characterized by sudden severe hypertension and renal failure, poses a life-threatening emergency. The patient's clinical features, including skin changes and abnormalities on nailfold capillaroscopy, facilitated the diagnosis of diffuse scleroderma. Comprehensive diagnostic investigations revealed multisystem involvement. Management involved angiotensin-converting enzyme inhibitors, hydroxychloroquine, and packed red cell transfusions, highlighting a holistic therapeutic approach. This case underscores the importance of recognizing diverse scleroderma manifestations in hypertensive emergencies for timely intervention and improved outcomes.
RESUMO
Methotrexate (MTX) is a well-established drug for the use of various neoplastic disorders. Recently, it has been widely used as a disease-modifying antirheumatic drug (DMARD) in low doses, mainly for rheumatoid arthritis (RA) and psoriasis. The drug is known to cause renal damage as well as be excreted via the kidneys, thus causing a higher incidence of adverse effects in patients with impaired renal function. The side effects of MTX toxicity range from mucocutaneous ulcers to nephrotoxicity and bone marrow depression, all of which are seen in this case. Here, we report an elderly male in his late 60s who was prescribed MTX 15 mg once a week along with folic acid 5 mg for RA by a general practitioner. Despite being prescribed once weekly, he continued to take MTX daily without following up with a physician for a span of five months. Following this, he presented to the medicine outpatient department with odynophagia due to oral ulcers for 10 days. He was diagnosed with MTX toxicity, causing nephropathy, myelosuppression, and mucocutaneous ulcerations. He was treated with injectable leucovorin 100 mg thrice a day until the toxicity subsided, leading to his eventual recovery.
