Mullighan1 1Department of Pathology and Hematological Malignancies Program, St Jude Children’s Research Hospital, Memphis, TN Our understanding of the genetic basis of childhood acute lymphoblastic leukemia (ALL) has been greatly advanced by genomic profiling and sequencing studies. These efforts have characterized the genetic basis of recently described and poorly understood subtypes of ALL, including early T-cell precursor ALL, Philadelphia chromosome–like (Ph-like) ALL, and ALL with intrachromosomal amplification of chromosome 21, and have identified several rational therapeutic targets in high-risk ALL, notably ABL1-class and JAK-STAT inhibitors in Ph–like ALL. Deep sequencing studies are also refining our understanding of the genetic basis of clonal heterogeneity and relapse. These studies have elucidated the nature of clonal evolution during disease progression and identified genetic changes that confer resistance to specific therapeutic agents, including CREBBP and NT5C2. Genomic profiling has also identified common and rare inherited genetic variants that influence the risk of developing leukemia. These efforts are now being extended to ALL in adolescents and adults with the goal of fully defining the genetic landscape of ALL to further improve treatment outcomes in high-risk populations. These studies initially used sequencing, have refined the classification of ALL microarray profiling of structural genetic changes (using single ● To appreciate variation in prevalence of ALL subtypes with nucleotide polymorphism arrays or array-based comparative genomic age hybridization) and gene expression and Sanger sequencing of ● To understand that specific genetic alterations are associated limited numbers of genes.

In the meantime discount aciclovir 800 mg visa anti viral fungal fighter, a few ran- domized studies compare such CD4-driven intervals with continuous administra- tion of ART buy aciclovir 400mg on-line symptoms hiv infection first week. The relevant data and results of these studies are given in Table 10. It is clear that the results of these randomized studies differ considerably. While TIBET, Staccato or ACTG 5170 produced the verdict that CD4 T cell-driven inter- ruptions are safe, two other studies, Trivacan and SMART came to other conclusions. In particular, the results of the SMART Study, which started in 2002, caused a sen- sation. In this, the largest randomized HIV study of all time, the cut-off levels for stopping ART were 350 cells/µl, and 250 cells/µl for re-initiating it. In the end, 318 centers in 53 countries recruited a total of 5472 patients. In 2006 an independent data safety monitoring board concluded that therapeutic interruptions result in an increased risk of AIDS – in the interruption arm, approximately twice as many AIDS illnesses were observed at follow-up, over an average of 18 months. This included severe opportunistic infections as well as malignant tumors. In fact, the overall risk was low, but so significantly elevated that the unusual and far-reaching decision was made to end the study. In addition it was observed that cardiovascular incidents in the interruption arm did not become less frequent, but actually increased. Staccato 430 >350 <350 Clinically safe (slightly more side effects in Ananworanich 2006 ART arm; more candidiasis in STI arm). No evidence of resistance ACTG 5170 167 >350 <250 In general safe, with risks only elevated when Skiest 2007 CD4 nadir was low LOTTI 329 >700 <350 Clinically safe. More pneumonias but less Maggiolo 2009 cardiovascular events, no evidence of resistance FU=follow up; Mo=months; BL=baseline Table 10. More recent studies showed that clinical and immunological disadvantages remained, even when ART was resumed (El Sadr 2008). However, even after SMART, not all questions were answered. A striking fact was the high incidence of clinical occurrences compared to Staccato, a study involving 430 patients. As measured by the AIDS/mortality rates of ART, there should have been at least 17 cases in Staccato – instead there was not one. Moreover the significantly higher risk of an AIDS-defining malignancy during therapy interruption (Silverberg 2007) was questionable as the majority of the patients who developed KS or lym- phoma in SMART had already suffered from AIDS illnesses before. Why were these patients enrolled in the SMART study? One can only speculate about the increased cardiovascular, renal and hepatic inci- dents in the interruption group. How many patients interrupted therapy that should not have? How many patients with chronic hepatitis B experienced a HBV rebound during interruption, how many patients with previous HIVAN developed renal prob- lems, how many patients decided to stop concomitant medications (statins) that led to a cardiovascular event? However, there are some newer studies that show an increase of inflammatory or coagulation parameters during therapy interruption (Kuller 2008, Calmy 2009, Baker 2011, Olmo 2012). Cystatin C, a parameter for renal dysfunction, also increases (Mocroft 2009). Especially the argument that therapy interruptions improve quality of life is no longer the case. One can discuss higher values for initiation and interruptions, but there will certainly not be any second SMART with new starting/stopping values for some time. Patients should always be encouraged to continue ART. Thanks to the new classes, the options have widened, enabling us to respond to side effects. If the patient, after discussion, still wishes to interrupt therapy the wish should be respected. The inter- ruption will happen anyway with or without the doctor’s agreement.

Fecal incontinence is less frequent but is highly prevalent in the very old age group and especially in nursing homes. Prevalence on data of symptoms of PFD in the developing world is scarce.
