RESUMO

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.

RESUMO

Abstract The combination of trimethoprim-sulfamethoxazole (TMP-SMZ or cotrimoxazole) has a bactericidal effect on gram-positive cocci and gram-negative bacilli. It is used clinically for skin and soft tissue, respiratory and urinary tract infections, and is also relevant for prophylaxis and treatment of opportunistic infections in immunosuppressed patients. Its use at established doses in immunocompetent patients is safe, with a low rate of adverse events. However, in immunosuppressed individuals (human immunodeficiency virus [HIV], transplants, or steroid users), the adverse effects (AEs) of this medication reach 83%; and, when administered parenterally at high doses, lactic acidosis has been documented secondary to the polyethylene glycol vehicle. We present two cases of patients who ingested an overdose of TMP-SMZ and developed type 2 renal tubular acidosis (RTA), which has not been described with this medication, and whose hyperlactatemia is not explained by the polyethylene glycol excipient, as it was taken orally.


Resumen La combinación de trimetoprim-sulfametoxazol (TMP-SMZ o cotrimoxazol) tiene efecto bactericida sobre cocos gram positivos y bacilos gram negativos, con uso clínico en infecciones de piel y tejidos blandos, del tracto respiratorio y urinario, además con relevancia en la profilaxis y tratamiento de infecciones oportunistas en pacientes inmunosupresos. Su uso en pacientes inmunocompetentes a dosis establecidas es seguro, con una baja tasa de eventos adversos. Sin embargo, en población con inmunosupresión: virus de inmunodeficiencia humana (VIH), trasplante, o usuarios de esteroides; los efectos adversos (EA) por este medicamento alcanzan 83% y por administración parenteral en dosis elevadas se ha documentado acidosis láctica secundaria al vehículo polietilenglicol. Presentamos dos casos de pacientes que ingirieron TMP-SMZ en sobredosis, desarrollando acidosis tubular renal (ATR) tipo 2, la cual no se ha descrito en este medicamento y cuya hiperlactatemia no es explicable por el excipiente polietilenglicol debido a que el consumo fue oral.
