Reactivation of Chagas Disease in a Patient With Follicular Lymphoma Diagnosed by Means of Quantitative Real-Time Polymerase Chain Reaction

چکیده
We report a case of Chagas disease reactivation in a patient with stage IIb follicular lymphoma in the cecum. He was admitted to the hospital with neutropenia and fever. He had a history of right hemicolectomy 6 months earlier and had received the sixth cycle of chemotherapy with cyclophosphamide/doxorubicin/vincristine/prednisone/rituximab. Blood and urine cultures were negative, but the fever persisted. Reactivation of Chagas disease was confirmed by means of quantitative real-time polymerase chain reaction (qRT-PCR). Parasitic load was 577 950 parasite equivalents/mL. The patient began treatment with benznidazole 5 mg/k per day every 12 hours. After 1 month, the qRT-PCR control was undetectable. The patient completed 60 days of treatment and is currently asymptomatic. Trypanosoma cruzi qRT-PCR may become a useful diagnostic method for reactivation of Chagas disease.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe adverse cutaneous reactions to drugs. We describe the case of a 19 year old patient with SJS/TEN overlap syndrome, who developed severe interstitial pneumonia after she had received antiepileptic drugs. A cytomegalovirus infection was diagnosed by Real Time Polymerase Chain Reaction (RT-PCR) detection on Bronchoalveo...
متن کاملComparison of Quantitative Real-Time Polymerase Chain Reaction (qRT-PCR) and Agglutination Assays in Diagnosis of Brucellosis in Golestan Province, North of Iran
Introduction: Brucellosis is one of the most common zoonotic infections worldwide. The clinical symptoms of brucellosis are similar to a wide range of diseases; hence, reliable diagnostic and laboratory methods are required to identify the causative agent. Iran is an endemic region of brucellosis, and many patients are misdiagnosed due to the nature of the infection. In this study, we aimed to ...

Objective Maternal-fetal RhD antigen incompatibility causes approximately 50% of clinically significant alloimmunization cases. The routine use of prophylactic anti-D immunoglobulin has dramatically reduced hemolytic disease of the fetus and newborn. Recently, fetal RHD genotyping in RhD negative pregnant women has been suggested for appropriate use of anti-D immunoglobulin antenatal prophylaxi...

BACKGROUND Reactivation of chronic Chagas disease, which occurs in approximately 20% of patients coinfected with HIV/Trypanosoma cruzi (T. cruzi), is commonly characterized by severe meningoencephalitis and myocarditis. The use of quantitative molecular tests to monitor Chagas disease reactivation was analyzed. METHODOLOGY Polymerase chain reaction (PCR) of kDNA sequences, competitive (C-) PC...
