RESUMO

Patients treated for adult T-Cell leukemia/lymphoma (ATL) have a poor prognosis and are prone to infectious complications which are poorly described. As the French reference center for ATL, we retrospectively analyzed 47 consecutive ATL (acute, n = 23; lymphoma, n = 14; chronic, n = 8; smoldering, n = 2) patients between 2006 and 2016 (median age 51 years, 96% Afro-Caribbean origin). The 3-year overall survival (OS) was 15.8%, 11.3%, and 85.7% for acute, lymphoma, and indolent (chronic and smoldering) forms respectively. Among aggressive subtypes, 20 patients received, as frontline therapy, high dose of zidovudine and interferon alfa (AZT-IFN⍺) resulting in an overall response rate (ORR) of 39% (complete response [CR] 33%) and 17 chemotherapy resulting of an ORR of 59% (CR 50%). Ninety-five infections occurred in 38 patients, most of whom had an acute subtype (n = 73/95; 77%). During their follow-up, patients receiving frontline chemotherapy or frontline AZT-IFNα developed infections in 74% (n = 14/19) and 89% (n = 24/27) of the cases respectively. Sixty-four (67%) of infections were microbiologically documented. Among them, invasive fungal infections (IFI, n = 11) included 2 Pneumocystis jirovecii pneumonia, 5 invasive aspergillosis, and 4 yeast fungemia. IFI exclusively occurred in patients with acute subtype mostly exposed to AZT-IFNα (n = 10/11) and experiencing prolonged (> 10 days) grade 4 neutropenia. Patients with aggressive subtype experiencing IFI had a lower OS than those who did not (median OS 5.4 months versus 18.4 months, p = 0.0048). ATL patients have a poor prognosis even in the modern era. Moreover, the high rate of infections impacts their management especially those exposed to AZT-IFNα.

RESUMO

BACKGROUND: Transfusion-related acute lung injury (TRALI) is a major cause of transfusion-related mortality and morbidity. Epidemiologic studies using data from national transfusion schemes can help achieve a better understanding of TRALI incidence. STUDY DESIGN AND METHODS: A multidisciplinary working group analyzed TRALI cases extracted from the French Hemovigilance Network Database (2007-2008). All notified cases were reviewed for diagnosis. Those meeting the Canadian Consensus Conference criteria for TRALI were classified according to imputability to transfusion and clinical severity. Patient data (clinical characteristics, number and types of products transfused, and serology results) were obtained. RESULTS: There were 62 TRALI cases and 23 possible TRALI cases during the 2-year period. An immune-mediated mechanism was identified in 30 of 50 TRALI cases with complete serology. TRALI was considered to be the cause of death in 7.1% of patients and might have contributed to death in an additional 9.4% of TRALI or possible TRALI patients. Occurrence ranked high in obstetrics (15%), after surgery (34%), and in hematologic malignancies (21%). Single-donor high-plasma-volume components were involved in half of the cases where the implicated blood product could be determined and carried the highest risk per component (1:31,000 for single-donor fresh-frozen plasma units and apheresis platelet [PLT] concentrates, and 1:173,000 for red blood cells). No incident could be definitively related to the transfusion of solvent/detergent-treated pooled plasma (>200,000 units transfused), nor to pooled PLT concentrates. CONCLUSION: The proportion of TRALI cases related to plasma-rich components was lower than previously described.

RESUMO

BACKGROUND: With the lengthening of life expectancy among HIV-positive subjects related to the use of highly active antiretroviral treatments, an increased risk of cancer has been described in industrialized countries. The question is to determine what occurs now and will happen in the future in the low income countries and particularly in sub-Saharan Africa where more than two-thirds of all HIV-positive people live in the world. The objective of our paper is to review the link between HIV and cancer in sub-Saharan Africa, putting it in perspective with what is already known in Western countries. METHODS AND FINDINGS: Studies for this review were identified from several bibliographical databases including Pubmed, Scopus, Cochrane, Pascal, Web of Science and using keywords "HIV, neoplasia, epidemiology and Africa" and related MesH terms. A clear association was found between HIV infection and AIDS-classifying cancers. In case-referent studies, odds ratios (OR) were ranging from 21.9 (95% Confidence Interval (CI) 12.5-38.6) to 47.1 (31.9-69.8) for Kaposi sarcoma and from 5.0 (2.7-9.5) to 12.6 (2.2-54.4) for non Hodgkin lymphoma. The association was less strong for invasive cervical cancer with ORs ranging from 1.1 (0.7-1.2) to 1.6 (1.1-2.3), whereas ORs for squamous intraepithelial lesions were higher, from 4.4 (2.3-8.4) to 17.0 (2.2-134.1). For non AIDS-classifying cancers, squamous cell conjunctival carcinoma of the eye was associated with HIV in many case-referent studies with ORs from 2.6 (1.4-4.9) to 13.0 (4.5-39.4). A record-linkage study conducted in Uganda showed an association between Hodgkin lymphoma and HIV infection with a standardized incidence ratio of 5.7 (1.2-17) although OR in case-referent studies ranged from 1.4 (0.7-2.8) to 1.6 (1.0-2.7). Other cancer sites found positively associated with HIV include lung, liver, anus, penis, vulva, kidney, thyroid and uterus and a decreased risk of female breast cancer. These results so far based on a relatively small number of studies warrant further epidemiological investigations, taking into account other known risk factors for these tumors. CONCLUSION: Studies conducted in sub-Saharan Africa show that HIV infection is not only strongly associated with AIDS-classifying cancers but also provided some evidence of association for other neoplasia. African countries need now to implement well designed population-based studies in order to better describe the spectrum of AIDS-associated malignancies and the most effective strategies for their prevention, screening and treatment.

RESUMO

OBJECTIVES: The role of hepatitis C virus (HCV) infection in the pathogenesis of non-Hodgkin's lymphoma (NHL) is controversial. A high prevalence of HCV infection in patients with NHL has been reported in Italy and Japan. By contrast, several studies in Northern Europe and Canada have not found any increased prevalence of HCV in B-cell NHL, suggesting a possible geographic variation. We sought to determine whether such an association could be found in patients treated in the Rhone-Alpes region in south-east France. Our main interest was to identify histological subtypes preferentially linked to HCV. METHODS: We determined the prevalence of anti-HCV antibodies in 212 consecutive patients with B-cell NHL diagnosed in our institution between January 1997 and December 1998. The comparison group comprised 974 patients tested for HCV before transfusion at the same hospital during the same period. RESULTS: Anti-HCV antibodies were found in six (2.8%) NHL patients. The distribution by histopathological category was as follows: three gastric mucosa-associated lymphoid tissue (MALT) lymphomas, one marginal lymphoma and two diffuse large-cell lymphomas. Anti-HCV antibodies were found in 20 (2%) of 974 comparison patients. Overall, there was a positive but non-significant trend towards an association between NHL and HCV infection (odds ratio 1.31; 95% confidence interval 0.51-3.36). However, the prevalence of HCV antibodies was significantly higher in MALT lymphoma patients than in the comparison group (odds ratio 9.87; 95% confidence interval 2.59-37.69). CONCLUSIONS: To our knowledge, this is the first French study to show an association between HCV and MALT lymphoma. These results, although derived from a small number of patients, suggest a possible role of HCV in gastric MALT lymphomagenesis.

RESUMO

OBJECTIVE: To study the relation between smoking and non-Hodgkin's lymphoma (NHL), in the Rhône-Alpes region of France. METHODS: We conducted a hospital-based case-control study that included 180 cases of NHL and 360 age-, gender-matched hospital controls. Matched univariable and multivariable logistic regression models were used for analysis. RESULTS: For the whole study population as well as for men, smoking does not elevate the risk of NHL. However, the risk of NHL is higher for women who currently smoke compared to women who have never smoked (odds ratio [OR] = 2.40, 95% confidence interval [95% CI] = 1.19-4.84). Among ever smokers, the OR of NHL is 5.04 (95% CI = 1.40-18.12) for women who have smoked for more than 30 years compared with those who have never smoked. Similarly, women who started to smoke before the age of 20 years compared with women who have never smoked are at greater risk of developing NHL (OR = 2.40, 95% CI = 0.99-5.85). In the total population (women and men), smoking may be associated with one histologic subtype, follicular NHL with an adjusted OR for the current smokers compared to subjects having never smoked of 3.20, 95% CI = 0.79-12.97. CONCLUSIONS: In spite of the small number of subjects in the subgroups, a relation is observed between smoking and NHL among women, but not men, and in the total population a relation is suggested between smoking and follicular NHL.
