Leishmanization programmes in a hyperendemic area [Isfahan] and a high-risk group [army recruits and the Revolutionary Guard] are described and their effectiveness and complications are discussed. A trial of a non-living crude vaccine is outlined. More than two million people underwent leishmanization and it was found to reduce the incidence of the disease between one-sixth and one-eighth of its original level. The procedure is recommended whenever people are at a very high risk of contracting the disease

Sociocultural Background

The relation between drug addiction and tuberculosis was assessed in a comparative prevalence study. A group of 561 male addicts were compared with a group of 1532 non-addicts of similar sociocultural background. The results of infection rate showed a statistically significant difference X [2] = 72, P < 0.001] in the proportion of positive tuberculin sensitivity between the groups [66.7% among addicts versus 45.6% in the control group]. Fourteen active cases of pulmonary tuberculosis were found among the addicts with no case in the control group. This gives a prevalence rate of 2500/100 000 addicts, more than 150 times the rate in the general population. Thus, drug addicts are a high-risk group for tuberculosis and a "hidden source" of the disease in the community

Background: The AHA/ACC 2018 Cholesterol Guideline categorizes ASCVD patients into very high-risk vs. high-risk to guide intensive therapy. This categorization is based on clinical conditions, including reduced kidney function, but does not take into account albuminuria, the other kidney measure often available in clinical practice. Methods: We studied 838 participants with major ASCVD (myocardial infarction, ischemic stroke, or symptomatic peripheral artery disease) from the ARIC study at baseline (1996 - 98). We compared urine albumin-to-creatinine ratio (ACR) and the eight high-risk conditions of age 65+, reduced kidney function, diabetes, etc. in the AHA/ACC Guideline regarding their associations with composite outcome of all-cause mortality, myocardial infarction, ischemic stroke, and heart failure. We also evaluated risk classification by adding ACR to the eight high-risk conditions. Results: During a median follow-up of 8 years, 724 (86%) participants developed a composite outcome. ACR ≥30 mg/g was associated with the composite outcome (adjusted hazard ratio [aHR] 1.45 [95% CI 1.20, 1.75]) beyond the eight high-risk conditions (aHR of these conditions ranged from 0.96 to 2.46). The addition of ACR improved the c-statistic by 0.011 (95% CI 0.003-0.019) from 0.661 to 0.672. ACR classified 4.6% of high-risk group to very high-risk and 11.2% of very high-risk group to extremely very high-risk with a reasonable calibration (Figure). Even ACR ≥10 mg/g showed a significant aHR of 1.38 (1.17, 1.63) and classified 13.4% of high-risk and 18.1% very high-risk to a higher risk category. Of our patients with ASCVD, 77% had diabetes, hypertension, or low kidney function, clinical conditions in which the ACR assessment is recommended. Conclusions: In ASCVD, albuminuria was a strong predictor of major adverse cardiovascular outcome and improved risk prediction. Clinicians should pay attention to albuminuria, in addition to eGFR, when managing ASCVD patients.

Abstract In the German Multicenter ALL studies (GMALL) patients aged &gt;55 years with high risk (B-lineage ALL with WBC at diagnosis &gt;30000, late CR, t (4; 11), complex aberrant karyotype or prae-T or mature T-ALL) or very high risk (Ph+/BCR-ABL+) ALL are increasingly candidates for allogeneic stem cell transplantation (allogeneic SCT with a HLA identical sibling donor, MRD or a matched unrelated donor, MUD) or autologous SCT. Here, we report on 31 elderly patients transplanted within the GMALL studies 06/99 and 07/03. Median age of the patients was 61 years (56–65). 22 patients belonged to the very high risk group (VHR), 8 patients to the high risk group (HR) and 1 patient from the standard risk group (SR) was transplanted because of detection of minimal residual disease.17/31 patients were transplanted from a matched unrelated donor, 9/31 patients from a HLA identical sibling donor and 5/31 patients underwent autologous SCT. Conditioning regimens for MRD SCT were myeloablative (MAC) in 6 patients (TBI 12 Gy and chemotherapy n=2, radioimmunotherapy + chemotherapy n=2, chemotherapy only n=2) and 3 patients received reduced intensity conditioning (RIC).Conditioning regimens for MUD SCT changed over time with an increasing number of RIC in the study 07/03. In total, 7/17 patients received MAC (TBI 12 Gy and chemotherapy n=5, chemotherapy only n=2) and 10/17 patients received RIC. Conditioning regimens in autologous SCT were myeloablative (MAC) in 5/5 patients. Results: After allogeneic MRD SCT 4/9 patients (44%) are alive in CCR (d+ 24, d+ 611, d+ 1721, d+ 2321), 3/9 patients died due to leukemia, 2/9 due to transplant related mortality (TRM). After allogeneic MUD SCT 8/17 patients (46%) are alive in CCR (from d+ 165 to d+ 2176). 1 further patient is alive after re- SCT for treatment of relapse. 7/17 patients died due to TRM and 1 patient died due to relapse. After autologous SCT 2/5 patients are alive in CCR (d+ 1703, d+ 1731), 3/5 died due to relapse. Risk factors for TRM: In allo SCT and MAC 8/13 patients died due to TRM in contrast to 1/13 patients with RIC. In auto SCT none of the patients died due to TRM. Risk factors for relapse: In allogeneic MRD SCT 3/9 patients died due to relapse and 2/17 patients relapsed after MUD SCT. Due to the small number of patients, no difference between MAC and RIC could be found. In autologous SCT 3/5 patients died due to relapse. In conclusion: The study shows that allo MRD but also MUD SCT is very effective in a selected population of elderly ALL patients. Since the survival of elderly patients with chemotherapy only is about 25%, more patients should be encouraged to have a MRD or MUD SCT.

The rate of thromboembolic complications associated with thrombophilia is very high; therefore the detection of thrombophilia mutations in the high-risk group of patients is important for the prevention of morbidity, mortality and obstetric losses. The problem of thrombophilia is dealt with by doctors of various specialties: laboratory stuff, geneticists, vascular surgeons, hematologists, neurologists, cardiologists and obstetricians-gynecologists. At the same time, patients with spontaneous thrombosis are followed-up for years without proper examination for thrombophilia. Considering that pregnancy is a condition associated with a high probability of re-thrombosis, it is advisable to determine the cause and tactics of management and treatment of pregnant women as early as possible during the period of pregnancy.

Aim. To assess the specifics of antihypertension therapy (AHT) in hypertensives of various cardiovascular risk, in the registry of chronic non-communicable diseases in Tyumenskaya oblast.Material and methods. A random sample studied, of 1704 patients with hypertension, inhabitants of Tyumenskaya oblast (region), ascribed to dispensary follow-up. Mean age 62±7,5 y.o. Of those 31,5% (n=537) males. The prevalence and efficacy of AHT assessed according to cardiovascular risk level. The significance was evaluated with the criteria χ2.Results. AHT was characterized by the growth of the frequency of treatment approaches with cardiovascular risk consideration. Regular treatment took 33,9% patients of low and moderate risk vs 41,3% of high and very high (p<0,01). In the male group such tendency also took place. Gender specifics of AHT was characterized by that in the groups of high and very high risk females took medications significantly more commonly than males — 46,6% vs 29,1% in high risk group (p<0,01) and 47,5% vs 30% in very high risk group (p<0,01). With the increase of the risk level, there was decline of treatment efficacy — from 95% in low risk group to 32,5% in very high risk group; 53,1% of the participants were taking monotherapy, 32,9% — two drugs, 14,0% — ≥3 drugs. With the increase of risk grade there is tendency to increase of combinational AHT, however with no significant increase of efficacy. Treatment efficacy in high and very high risk patients comparing to patients with low and moderate risk was significantly lower — 33,1% vs 69,7% (p<0,01), respectively. Statins intake among the high and very high risk patients was 10,6-11,0% males and 7,8% females (p<0,05).Conclusion. AHT in hypertensives in Tymenskaya oblast, under dispensary follow-up, is characterized by insufficient usage of combinational drugs. With the raise of cardiovascular risk there is tendency to higher rate of combinational AHT. However there is no significant increase in efficacy of treatment with the increase of medications number. A very low rate of statins intake is noted. The obtained specifics witness for the necessity to optimize AHT among the high and very high risk patients — inhabitants of Tyumenskya oblast.

Objective: The main objective was to develop a decision-support tool to assess the risk of caregiver burden, the Caregiver Risk Evaluation (CaRE) algorithm. Methods: Home care clients were assessed using the Resident Assessment Instrument for Home Care (RAI-HC). Their caregiver completed the 12-item Zarit Burden Interview (ZBI), the main dependent measure, which was linked to the RAI-HC. Results: In the sample ( n = 344), 48% were aged 85+ years and 61.6% were female. The algorithm can be collapsed into four categories (low, moderate, high, and very high risk). Relative to the low-risk group, clients in the very high-risk group had an odds ratio of 5.16 (95% confidence interval: [2.05, 12.9]) for long-term care admission, after adjusting for client age, sex, and regional health authority. Discussion: The CaRE algorithm represents a new tool to be used by home care clinicians as they proactively plan for the needs of clients and their caregivers.

8045 Background: The PTLD-1 trials have established risk-stratified sequential treatment of B-cell PTLD. After rituximab induction, patients (pts) in complete remission (25 %) received rituximab consolidation, while all others received R-CHOP. The PTLD-2 trial tests modified risk-stratification including clinical risk factors. These are the results of the 2nd scheduled interim analysis (40/60 planned pts). Methods: The prospective, multicenter phase II PTLD-2 trial (NCT02042391) enrols treatment-naïve adult SOT recipients with CD20-positive PTLD. Key exclusion criteria are CNS involvement, ECOG > 2, pregnancy, and severe organ dysfunction or severe, active infection. Treatment consists of rituximab (1400 mg SC; first application 375 mg/m2 IV) on days 1, 8, 15 and 22. After restaging, pts in CR as well as those in PR with ≤ 2 IPI risk factors at diagnosis (low-risk group) continue with four three-weekly courses of rituximab. Most other pts (high-risk group) receive 4 cycles of R-CHOP-21, while thoracic SOT recipients who progress under rituximab (very-high-risk group) receive six cycles of alternating R-CHOP-21 and R-DHAOx. The primary endpoint (event-free survival in the low-risk group) is not analyzed here. Secondary endpoints presented here are response and overall response (ORR) by computed tomography, overall survival (OS), time to progression (TTP) and treatment-related mortality (TRM) overall and by risk group. Results: 40 pts were recruited at 12 centers (2015 – 2019). 21/40 were kidney, 11 lung, 4 liver, 3 heart, and 1 liver/kidney transplant recipients. Median age was 54 years. 38/40 PTLD were monomorphic and 15/40 EBV-associated. 38 pts were evaluated for response at interim staging: 13 were allocated to the low-risk, 17 to the high-risk and 8 to the very-high-risk group. ORR was 28/30 (93 %, CR: 16/30 [53 %]). With a median follow-up of 1.9 years, the 1-year/3-year Kaplan-Meier (KM) estimates of TTP and OS in the intention-to-treat population (40 pts) were 85 %/80 % and 70 %/70 %, respectively. In the low-risk group, the 2-year KM estimate of OS was 100 %. The frequency of infections (all grades) was 50 %, and TRM occurred in 3/40 pts (8 %). Conclusions: One third of enrolled pts were treated in the low-risk group and the recruitment goal for evaluation of the primary endpoint will likely be reached. Interim efficacy and toxicity data with rituximab SC and modified risk-stratification are encouraging despite the inclusion of 35 % thoracic SOT recipients. Clinical trial information: NCT02042391 .

Abstract Abstract 2741 Cytogenetic analyses are essential for stratification and prognosis in childhood AML. We analysed the frequency of chromosomal aberrations and the outcome according to the cytogenetic findings in 386 patients with data (92%) out of the total group of 422 German patients in study AML-BFM 2004. The aim was to evaluate the prognostic impact of specific chromosomal aberrations in a large cohort of patients treated according to this BFM protocol. Patients were <18 years of age and were diagnosed between 2004 and 2009. According to the AML-BFM risk criteria based on morphology, genetics and response on day 15 of therapy, patients were assigned to a high-risk (HR) and a standard risk (SR) group. Cytogenetic and FISH analyses-as well as RT-PCR if indicated-were performed according to standard protocols on bone marrow or peripheral blood prior to therapy. Results: the number of patients in different karyotypic groups and their outcome are given in the table below: SE = standard error, pOS = probability of overall survival, pEFS = probability of event-free survival, CIR = cumulative incidence of relapse at 5 years All patients with t(15;17) and/or PML/RARα fusion gene are surviving disease free, except for two patients who died during the first two weeks of treatment. It is noteworthy that all children with inv(16) and/or CBFβ/MYH11 fusion gene are surviving (pOS=100%). Compared to the results of study AML BFM 98, outcome of patients with MLL-rearrangements was significantly higher in study AML BFM 2004 (pEFS 35%, SE 5%, vs. pEFS 55%, SE4%) which may be due to more intensive treatment with liposomal daunorubicin (L-DNR) and 2-chlorodeoxyadenosine (2-CDA). Patients with the translocation t(9;11)(p22;q23) and/or the MLL/AF9 fusion gene [n=43] had a pEFS of 60% (SE 9%) and a pOS of 80% (SE 6%), whereas patients with translocation t(10;11)(p12;q23) and or the MLL/AF10 fusion gene [n=13] showed a poor outcome with a pEFS of 23% (SE 13%) and a pOS of 59% (SE 14%). Based on a literature review we defined a very-high-risk group (see definition in the table) which showed a very poor outcome both in study AML BFM 2004 (n=16, pEFS 30%, SE12%) and AML BFM 98 (n=22, pEFS 14%, SE 7%). In this very high risk group 25 patients of both studies achieved first complete remission (1st CR); 11 of them underwent allogeneic stem cell transplantation (SCT) (pEFS 52%, SE16%), 14 patients did not (pEFS of the 12 patients who had an EFS of at least 0.44 years: 13%, SE 11%), Mantel-Byar p=0.17). Conclusion: Our results confirm the favourable prognosis for patients showing the rearrangements t(8;21), t(15;17) and inv(16) and the unfavourable prognosis for those with complex karyotypes (3 or more chromosomal aberrations), deletions in 12p and t(10;11)(p12;q23). According to these results stratification of patients in further AML BFM studies will be even more differentiated, and patients of a genetically defined very high-risk group will have an indication for SCT in 1.CR.
