Organizing pneumonia due to anti-synthetase syndrome: Presentation of a clinical case

Introduction: Organizing pneumonia is a rare clinico-pathological syndrome. This crypto-genic or secondary condition is of unknown origin, and may be infectious, or associated with autoimmune diseases, cancer, drugs, or radiation. Case description: The case is presented of a 52-year-old patient who was diagnosed with organizing pneumonia secondary to anti-synthetase syndrome. Discussion: It is intended to make known that not all pulmonary consolidative clinical pictures correspond to infectious processes. In this case, an organizing pneumonia secondary to anti-synthetase syndrome is documented. Despite being a disorder that is classified as an idiopathic inflammatory myopathy, it manifests as an interstitial lung disease with predominantly respiratory symptoms.

Introducción: La neumonía organizativa es un síndrome clínico-patológico poco frecuente, dentro del cual se desconoce la etiología de la denominada neumonía criptogénica o secundaria, que puede ser infecciosa o asociada con enfermedades autoinmunes, cáncer, fármacos o radiación. Descripción del caso: Se presenta el caso de una paciente de 52 arios a quien se le diagnostica neumonía organizativa secundaria a síndrome antisintetasa. Discusión: Se busca dar a conocer que no todos los cuadros clínicos de consolidación pulmonar corresponden a procesos infecciosos. En este caso se documentó una neumonía organizativa secundaria a síndrome antisintetasa, la cual a pesar de ser una patología que se cataloga como una miopatía inflamatoria idiopática, se manifestó como una enfermedad pulmonar intersticial con síntomas predominantemente respiratorios.

Losartan-induced DRESS syndrome

Abstract Introduction: drug reactions with eosinophilia and systemic symptoms, known as DRESS syndrome, are a hypersensitivity reaction to medications which can lead to skin lesions and internal organ involvement. This syndrome has typically been associated with a wide variety of medications, including aromatic anticonvulsants, allopurinol and antibiotics as the main culprits. Objective: we present the case of a patient with DRESS syndrome secondary to losartan, manifesting skin symptoms and mild hepatic involvement. Up until now, there have been no reports of losartan as the cause of this condition. Prompt treatment was instated including the withdrawal of the offending medication and initiation of oral systemic steroids, with a satisfactory response. Conclusion: caregivers should be alert to the appearance of skin lesions with the use of different groups of medications, not just those typically reported, since any medication could potentially cause a hypersensitivity reaction.
