RESUMEN

OBJECTIVE: Chagas disease (CD) globalization facilitated the co-infection with Human Immunodeficiency Virus (HIV) in endemic and non-endemic areas. Considering the underestimation of Trypanosoma cruzi (T. cruzi)-HIV co-infection and the risk of life-threatening Chagas Disease Reactivation (CDR), this study aimed to analyze the major co-infection clinical characteristics and its mortality rates. METHODS: This is a cross-sectional retrospective multicenter study of patients with CD confirmed by two serological or one parasitological tests, and HIV infection confirmed by immunoblot. CDR was diagnosed by direct microscopy with detection of trypomastigote forms in the blood or other biological fluids and/or amastigote forms in inflammatory lesions. RESULTS: Out of 241 patients with co-infection, 86.7% were from Brazil, 47.5% had <200 CD4+ T cells/µL and median viral load was 17,000 copies/µL. Sixty CDR cases were observed. Death was more frequent in patients with reactivation and was mainly caused by CDR. Other causes of death unrelated to CDR were the manifestation of opportunistic infections in those with Acquired Immunodeficiency Syndrome. The time between the co-infection diagnosis to death was shorter in patients with CDR. Lower CD4+ cells count at co-infection diagnosis was independently associated with reactivation. Similarly, lower CD4+ cells numbers at co-infection diagnosis and male sex were associated with higher lethality in CDR. Additionally, CD4+ cells were lower in meningoencephalitis than in myocarditis and milder forms. CONCLUSION: This study showed major features on T. cruzi-HIV co-infection and highlighted the prognostic role of CD4+ cells for reactivation and mortality. Since lethality was high in meningoencephalitis and all untreated patients died shortly after the diagnosis, early diagnosis, immediate antiparasitic treatment, patient follow-up and epidemiological surveillance are essentials in T. cruzi/HIV co-infection and CDR managements.

RESUMEN

Seven months after undergoing kidney transplantation, a 56-year-old woman presented with papules and ulcers in her right forearm. The patient received antibiotics for 8 months with limited improvement. Eleven months after symptom onset, she presented with acute arthritis in her left knee. Asynovial fluid culture yielded Mycobacterium tuberculosis, and a forearm ulcer biopsy showed granulomatous inflammation. After surgical fistulectomy and 12 months of tuberculosis treatment, she was cured. Chronic cutaneous ulcers and articular manifestations in TB are rare, but they should always be considered in the differential diagnosis for immunosuppressed patients. Surgical intervention and prolonged treatment might be necessary.

After surgical fistulectomy and 12 months of tuberculosis treatment, she was cured. Chronic cutaneous ulcers and articular manifestations in TB are rare, but they should always be considered in the differential diagnosis for immunosuppressed patients.
