Role of miRNAs in Human T Cell Leukemia Virus Type 1 Induced T Cell Leukemia: A Literature Review and Bioinformatics Approach. Int J Mol Sci 2022; 23:ijms23105486.

Abstract
Human T cell leukemia virus type 1 (HTLV-1) was identified as the first pathogenic human retrovirus and is estimated to infect 5 to 10 million individuals worldwide. Unlike other retroviruses, there is no effective therapy to prevent the onset of the most alarming diseases caused by HTLV-1, and the more severe cases manifest as the malignant phenotype of adult T cell leukemia (ATL). MicroRNA (miRNA) dysfunction is a common feature of leukemogenesis, and it is no different in ATL cases. Therefore, we sought to analyze studies that reported deregulated miRNA expression in HTLV-1 infected cells and patients’ samples to understand how this deregulation could induce malignancy. Through in silico analysis, we identified 12 miRNAs that stood out in the prediction of targets, and we performed functional annotation of the genes linked to these 12 miRNAs that appeared to have a major biological interaction. A total of 90 genes were enriched in 14 KEGG pathways with significant values, including TP53, WNT, MAPK, TGF-β, and Ras signaling pathways. These miRNAs and gene interactions are discussed in further detail for elucidation of how they may act as probable drivers for ATL onset, and while our data provide solid starting points for comprehension of miRNAs’ roles in HTLV-1 infection, continuous effort in oncologic research is still needed to improve our understanding of HTLV-1 induced leukemia.

Abstract
Adult T-cell leukemia/lymphoma (ATLL) is a peripheral T-cell neoplasm caused by the human T-cell leukemia virus type 1 (HTLV-1). It is characterized by a short survival time and lack of response to chemotherapy. We report a case of a 56-year-old woman, from the Brazilian northeast state of Bahia, who presented with a 2-month history of infiltrated papular and nodular skin lesions, especially on her forehead and also on her lower and upper limbs. Laboratory tests revealed positive serology for HTLV-1. Histopathological findings and the immunohistochemical profile confirmed the diagnosis of adult T-cell lymphoma/leukemia. A month after the diagnosis, the patient presented acute fatigue and pronounced paleness of the skin, dying of septic shock after her first chemotherapy cycle. The aim of this case report was to emphasize the importance of maintaining high clinical suspicion for ATLL, considering the epidemiological profile of the disease, especially for patients whose only early symptoms are cutaneous lesions.

Abstract
Resumo Introdução O estudo buscou identificar o conhecimento de mulheres acometidas pelo HTLV acerca da infecção, além de descrever a experiência do adoecimento e limitações impostas pelo vírus. Método Trata-se de uma pesquisa descritiva, com abordagem qualitativa. Participaram 12 mulheres acometidas pelo HTLV, atendidas no ambulatório de Infectologia de um hospital universitário em Salvador (BA) e no Centro de Testagem e Aconselhamento em Santo Antônio de Jesus (BA). A análise deu-se com base no Discurso do Sujeito Coletivo. Resultados Os resultados demonstram que é notável o desconhecimento em relação ao HTLV. O adoecimento é representado por dor, comprometimento dos membros inferiores e relaxamento dos esfíncteres. O HTLV impõe limitações nas atividades de vida diária e acarreta mudanças no cotidiano e na vivência das mulheres soropositivas. Conclusão Os dados empíricos confirmam a importância da realização de estudos, análise e discussão sobre o HTLV para o desenvolvimento de políticas e estratégias para o enfrentamento das doenças decorrentes da infecção.

Abstract
BACKGROUND Primary cutaneous lymphomas (PCL) are a group of extranodal non-Hodgkin lymphomas presenting with no evidence of extracutaneous disease at the time of diagnosis. Few longitudinal studies of PCL have been conducted, particularly in South American populations. Our objective was to describe the behavior of PCL and evaluate patient survival in a cohort of patients from southern Brazil. METHODS We conducted a retrospective cohort study of all patients with a histopathological diagnosis of PCL receiving care at a tertiary referral center in southern Brazil from 2000 to 2012. Clinical, laboratory, and histopathological data, treatment variables, and survival curves were analyzed. RESULTS Eighty-nine patients with PCL were included, with a mean age at diagnosis of 58.9 years. Cutaneous T-cell and natural killer (NK) cell lymphomas (CTCL/NKCL) accounted for 78.4% of cases and cutaneous B-cell lymphomas (CBCL) for 21.6%; 57.4% of patients with CTCL/NKCL and 50% of patients with CBCL were male. Half of all cases were mycosis fungoides (MF). The 5-year survival rate was 74.8% for MF, 61% for Sézary syndrome, 87.5% for primary cutaneous CD30+ lymphoproliferative disorders, and 88.9% for primary cutaneous follicle center lymphoma. CONCLUSIONS In this cohort of patients with PCL from southern Brazil, CTCL/NKCL was more prevalent than CBCL, and the MF subtype was predominant. Survival curves were similar to those reported in the literature, except for Sézary syndrome, which had a better prognosis in this sample.

Abstract
Cutaneous lymphoid hyperplasia (CLH) can be idiopathic or secondary to external stimuli, and is considered rare in tattoos. The infiltrate can be predominantly of B or T-cells, the latter being seldom reported in tattoos. We present a case of a predominantly T CLH, secondary to the black pigment of tattooing in a 35-year-old patient, with a dense infiltrate of small, medium and scarce large T-cells. Analysis of the rearrangement of T-cells receptor revealed a polyclonal proliferation. Since the infiltrate of CLH can simulate a T lymphoma, it is important to show that lesions from tattoos can have a predominance of T-cells.

Abstract
Human T-cell leukemia virus type 1 (HTLV-1), the first human retrovirus to be discovered, is present in diverse regions of the world, where its infection is usually neglected in health care settings and by public health authorities. Since it is usually asymptomatic in the beginning of the infection and disease typically manifests later in life, silent transmission occurs, which is associated with sexual relations, breastfeeding, and blood transfusions. There are no prospects of vaccines, and screening of blood banks and in prenatal care settings is not universal. Therefore, its transmission is active in many areas such as parts of Africa, South and Central America, the Caribbean region, Asia, and Melanesia. It causes serious diseases in humans, including adult T-cell leukemia/lymphoma (ATL) and an incapacitating neurological disease (HTLV-associated myelopathy/tropical spastic paraparesis [HAM/TSP]) besides other afflictions such as uveitis, rheumatic syndromes, and predisposition to helminthic and bacterial infections, among others. These diseases are not curable as yet, and current treatments as well as new perspectives are discussed in the present review.
