Background HIV infection predisposes to several neoplastic conditions, especially non-Hodgkin lymphoma and Kaposi's sarcoma, and also intraepithelial cervical neoplasia, anal neoplasia [1,2] For neoplasias associated with oncogenic human viruses, the role of HIV is most probably linked to its immunosuppressive effect and interference with immune-mediated tumour surveillance [2,3,4] ¹ Goedert, J.

Objectives To assess : the spectrum prevalence evolution of AIDS-related malignancies in teenagers horizontally infected with HIV-1 during their infancy
Material and methods retrospective study, from 01.01.2000 to 31.12.2009, on a cumulative group of 594 adolescents (according to Tanner classification), born and horizontally infected with HIV-1 (mainly nosocomial) between 1988 and 1990, followed up by Regional Center for Evaluation and Monitoring of HIV/AIDS Infection, Craiova, Romania Patients (Px) were clinically, biologically and imaging evaluated; diagnosis of certainty for malignant condition has been histopathologically established
Results-1 21 Px (3.5%) have been diagnosed with AIDS- associated malignancies, gender ratio M/F = 14/7 (66.7% / 33.3%) mean age when malignancy has been diagnosed = 15 [12; 18] years The spectrum and prevalence of malignancies: 13 Px (61.9%)- non-Hodgkin lymphoma (NHL), of which: - 8 Px (38.2%)- diffuse large B-cell NHL - 2 Px (9.5%) - primary central nervous system lymphoma - 2 Px (9.5%) - Burkitt lymphoma - 1 Px (4.7%) – marginal zone B-cell NHL 8 Px (38.1%) - Kaposi sarcoma
Results-2 The average time between diagnosis of HIV infection and identifying neoplasia has been 6.3 [0; 15] years At the malignancy diagnosis: average CD4 count =116.6 [9; 267] cells/mm³ average HIV-RNA = 5.45 [3.89; 5.89] log10 copies/ml 11 Px (52.4%) were antiretroviral multiexperienced, 4 other Px (19%) were naïve (neoplasia highlighted HIV infection) All Px received ARTc, while chemotherapy courses has been introduced in Px diagnosed with lymphoma
Evolution 12 deaths (57.2%) – 11 lymphoma Px, one case of Kaposi sarcoma (also having concomitant pulmonary tuberculosis) - with an average survival time after diagnosis of 5.6 [1; 14] months 2 Px (9.5.%) with NHL demonstrated remission 7 Px (33.3%) with Kaposi sarcoma, treated only with ARV, were still alive after an average of 5.4 [1; 9] years of follow-up.
Case 1: Kaposi Sarcoma N.A, female, born in 1989 Late diagnosis of HIV infection in March 2008 (long term non progressor?) with a concomitant diagnosis of palatinal Kaposi sarcoma CD4 count=18 cells/mm³ HIV-RNA= 28.800 c/ml ARTc - 2NRTI+PI/r (no chemotherapy) August 2008: CD4=217 cells/mm³ HIV-RNA< 50 c/ml Complete remission of the sarcoma
Case 2: Burkitt lymphoma D.N. female, born in 1990 Diagnosed with HIV infection in 1996, EBV-Ig G anti EBNA, anti VCA-positives Burkitt lymphoma in 2001 When malignancy has been recognized: CD4= 152cells/mm³ ART: 2 NRTI - 1997 NNRTI+PI since 2000
Case 2: Burkitt lymphoma The ARTc regimen has been changed: 2 NRTI+PI/r She has received chemotherapy - CHOP (cyclophosphamidum- doxorubicinum- oncovin/vincristinum- prednisonum) regimen (photo has been taken after the first chemotherapy course) She died 6 months later due to renal failure
Case 3: Burkitt lymphoma D.F, male, born in 1988 Diagnosed with HIV infection -1993, EBV-Ig G anti EBNA, anti VCA-positives, ART since 1996, 2 NRTI+PI since 2002 CD4 count=632 cells/mm³-Feb.2006 Diagnosed with Burkitt lymphoma in May 2006 – mandibular tumour (CD4=212 cells/mm³) Only 4 months survival (mandibular, axilar, iliac tumours, medular invasion)
Case 4: Marginal zone B-cell NHL V.I, female, born in 1989, diagnosed with HIV infection in 1996 ART since 1996, 2 NRTI+PI/r since 2007 May 2008: CD4=431cells/mm³, HIV-RNA <50 copies/ml marginal zone B-cell NHL in August 2008
Case 4: Marginal zone B-cell non-Hodgkin lymphoma
Case 4: Marginal zone B-cell NHL Px starts radiation, but after two courses the swelling, which has had an initial tendency to remission, shows progression CT proves the presence of two intraconjunctival abscesses; lymphoma continues to progress and breaches the anterior right eye pole, requiring enucleation
Case 4: Marginal zone B-cell NHL A new CT exam rises suspicion of intracranial expansive formations in the frontal right lobe. Reassessment of CD4 lymphocytes shows their fall in (the new value at 148 cells/mm³) The Px died in October 2008 The case shows the fulminating progression of malignant lesions in a special host (previously stabilized in terms of clinical, immunological and virological aspects) and the rapid and profound impact on cellular immunity
Case 5: NHL D.N.. Male, born in 1988 Diagnosed with HIV infection in 1996 ART since 1996 Diagnosed with diffuse large B cell NHL in 2001 Chemotherapy: - COMP (cyclophosphamidum- oncovin/vincristinum - methotrexatum-prednisonum) regimen-18 months
Case 5: Large B cell non-Hodgkin lymphoma with nuclear pleomorphism and vascular invasion Hematoxylin-eosin stain, x 20 optical enlargement
Evolution, May 2008: Average well-being, BMI = 19 kg/m², oral thrush CD4 count = 71cells/mm³, HIV-RNA=31.400 c/ml, TG=367mg/dl A genotypic test has been performed and the following mutations have been revealed: RT mutation-D67N, T69D, V75T, M184V, T215F, K219Q; PR mutation- L10V, K20R, L24I, L33F, M36I, M46I, I50V, I54V, V77I, V82A
Taking into account the results of the genotypic test and considering the fact that the Px has been exposed, during 1999-2001, to NNRTI (with a subsequent clinical, immunological and virological failure due, probably, to the occurence of NNRTI resistance), the following regimen has been proposed: RAL + T20 + DRV/r After 12 months it is noted: Two minor episodes of respiratory infections, not requiring hospitalization A good immune reconstruction (CD4 count 384 cells/mm³) HIV-RNA undetectable (< 50 copies/ml after one month of treatment with the new regimen)
Due to adverse effects of T20 (occurence of subcutaneous nodules), a new regimen has been introduced: ABC + 3TC +RAL+DRV/r In August 2009: BMI = 23.7kg/ m² CD4 count = 541 cells/mm³ HIV-RNA< 50 copies/ml no signs of opportunistic diseases without relapses of NHL following hypolipemiant treatment maximal well-being and with social integration (student)
Conclusions in HIV-1 positive teenagers horizontally infected during infancy, AIDS-related malignancies have a relatively low prevalence when present, they are accompanied by an increased mortality in spite of appropriate diagnosis and treatment.
