Introduction: The spleen is a lymphoid organ that plays an important role in the body's defense against organisms, participation in blood filtration process, phagocytosis and immunoglobulin production. When splenectomy due to severe splenic trauma or hematological disorder is inevitable, spleen autotransplantation may be the only option to preserve the spleen. It has not been determined the structural rearrangements after transplanting in comparison with the amount of transplanted spleen. The aim of this study was to evaluate the histological changes of spleen autotransplanted in the omentum of rats. Materials and Methods: In this experimental study, 16 male Wistar rats underwent splenectomy and transplanting three pieces of splenic tissue consists of 10-15% of the greater omentum. The rats were divided to two equal groups; Eight caseswere randomly separated and followedfor 6 months (Group Au-6) and 8 other cases also were separated for 12 months' follow-up (group Au-12). At the end of follow-up period, after the re-operation of autotransplanted rats, the splenic tissues underwent the macroscopic and microscopic examination and two groups were compared together. Results: After laparotomy, splenic tissues were detected in all cases (8/8, 100%) of Au-6 group and 7 cases (87.5%) of Au-12 group. It’s observed no significant difference between two groups in the capsule around splenic tissue, organized structure, fibrosis and revascularization (P>0.05). The hemosiderin pigmentation was significantly higher in Au-12 group (P=0.03). Conclusions: The results of this study showed that autotransplanting about 15 percent of splenic tissue were associated with a high success rate in tissue structure rearrangement. Therefore, spleen autotransplantation even in small sizes was highly recommended in cases of unavoidable splenectomy.

Tonsils are one of the important secondary lymphoid organ in immune system. It remains controversial whether tonsillectomy results in decreased serum immunoglobulin level. The purpose of this study was to observe the effect of tonsillectomy on humoral immunity parameters among the patients with tonsillar disease. Total group A 70 patients up to the age of 18 years, who were enrolled for tonsillectomy and 30 age matched children group B were included for comparative study. Serum IgG, IgM and IgA levels were measured in all 70 patients before tonsillectomy and in 56 patients who came for 1st follow-up after one month and 30 patients who came for 2nd follow up after three months of tonsillectomy. Serum IgG, IgM and IgA levels were also measured in group B children. Serum IgG, IgM and IgA levels in patients of group A did not show any significant difference in comparison to group B. One month after tonsillectomy the level of IgG was slightly decreased and IgM and IgA were increased compared to preoperative value but not statistically significant. All IgG, IgM and IgA were also not significantly altered in comparison to group B. Three months after tonsillectomy serum IgG, IgM and IgA level were found decreased in comparison to pre operative value and group B, among which difference of only IgG was significant. After tonsillectomy humoral parameters were found reduced but overall impact on humoral immune status was not significantly altered.

Summary Aim: Tumor scintigraphy with 201-TICI is an established diagnostic method in the follow-up of differentiated thyroid cancer. We investigated the relationship between thyroglobulin (Tg) level and tumor detectability. Subject and methods: We analyzed the scans of 122 patients (66 patients with proven tumor). The patient population was divided into groups with Tg above (N = 33) and below (N = 33) 5 ng/ml under TSH suppression or above (N = 33) and below (N = 33) 50 ng/ml under TSH stimulation. Tumor detectability was compared by ROC-analysis (True-Positive-Fraction test, specificity 90%). Results: There was no significant difference (sensitivity 75% versus 64%; p = 0.55) for patients above and below 5 ng/ml under TSH suppression and a just significant difference (sensitivity 80% versus 58%; p = 0.04) for patients above and below 50 ng/ml under TSH stimulation. In 18 patients from our sample with tumor, Tg under TSH suppression was negative, but 201-TICI-scan was able to detect tumor in 12 patients. Conclusion: Our results demonstrate only a moderate dependence of tumor detectability on Tg level, probably without significant clinical relevance. Even in patients with slight Tg elevation 201-TICI scintigraphy is justified.

<p>Liver is an organ with complex metabolism. When the liver is inflamed, cellular immunity will defend against inflammatory agents by stimulating immune cells to produce reactive oxygen species (ROS). Excessive ROS accumulation cause oxydative stress with increased  liver malondialdehyde (MDA) level. Some researches showed that purple sweet potato contain flavonoids (anthocyanins) that functioned as antioxydants. This study aimed to show the prophylactic effect of purple sweet potato extract to the liver MDA level of male Wistar rats induced by carrageenan.</p><p>This study used post-only control group method using 18 male Wistar rats divided into 3 groups: group of rats without treatment, group of rats induced by 0,1 ml of 1% carrageenan by intraplantar injection on day-8, and group of rats given with 872 mg/kgBW of purple sweet potato extract for 7 days and induced by 0,1 ml of 1% carrageenan.

SummaryAim: Assessment of the clinical benefit of i.v. contrast enhanced diagnostic CT (CE-CT) compared to low dose CT with 20 mAs (LD-CT) without contrast medium in combined [18F]-FDG PET/CT examinations in restaging of patients with lymphoma. Patients, methods: 45 patients with non-Hodgkin lymphoma (n = 35) and Hodgkin's disease (n = 10) were included into this study. PET, LD-CT and CECT were analyzed separately as well as side-by-side. Lymphoma involvement was evaluated separately for seven regions. Indeterminate diagnoses were accepted whenever there was a discrepancy between PET and CT findings. Results for combined reading were calculated by rating indeterminate diagnoses according the suggestions of either CT or PET. Each patient had a clinical follow-up evaluation for >6 months. Results: Region-based evaluation suggested a sensitivity/specificity of 66/93% for LD-CT, 87%/91% for CE-CT, 95%/96% for PET, 94%/99% for PET/LD-CT and 96%/99% for PET/CE-CT. The data for PET/CT were obtained by rating indeterminate results according to the suggestions of PET, which turned out to be superior to CT. Lymphoma staging was changed in two patients using PET/ CE-CT as compared to PET/LD-CT. Conclusion: Overall, there was no significant difference between PET/LD-CT and PET/CE-CT. However, PET/CE-CT yielded a more precise lesion delineation than PET/LD-CT. This was due to the improved image quality of CE-CT and might lead to a more accurate investigation of lymphoma.

SummaryThe aim of this study was to assess the influence of background subtraction (BS) on estimation of differential kidney function (DF) on the static scintigraphy with 99mTc dimercaptosuccinic acid (DMSA) and dynamic scintigraphy with 99mTc mercaptoacetyltriglicine (MAG3) and to establish possible differences between DF values estimated with these methods. Patients, methods: Patients (n = 106) were selected among those scheduled to static and dynamic scintigraphies within 3 months, with no interim clinical and laboratory changes, regardless the kidney pathology. DF was estimated according to the uptake ratio method. Four background regions of interest (ROIs) were applied, identical for both studies, and DF values were recalculated after BS. The corrected values were compared to the values before correction, separately for DMSA and MAG3, and between the studies. The results showed that ROIs used introduce variable results for the same patients, predominantly when noncorrected DF values were <45%. There were no significant differences between DF values (corrected and noncorrected) obtained from static and dynamic scintigraphy in all groups of patients. Since numerous reasons can bring to the errors in DF estimation when BS is used, the conclusions are that it would probably be more accurate to avoid BS, particularly when DF values are compared in a patient follow-up, and when kidney function is normal. BS should be used, but always in the same way, only when there is a significant difference in kidney size, or when DF is <25%, since background activity is then considerable. MAG3 and DMSA can be equally used for DF estimation and their results compared in patient follow-up.

Background: Although cardiac resynchronisation therapy (CRT) is an important player in the treatment of heart failure (HF) patients, the proportion of CRT patients with no improvement in either echocardiographic or clinical parameters remains consistently high and accounts for about 30% despite meeting CRT implantation criteria. Furthermore, in patients suffering from HF, renal dysfunction accounts for as many as 30-60%. Accordingly, CRT may improve renal function inducing a systemic haemodynamic benefit leading to increased renal blood flow. Objectives: The aim of the present study was to evaluate the importance of renal function in response to resynchronisation therapy during a 12-month follow-up period. Materials and methods: The study consisted of 46 HF patients qualified for implantation of cardiac resynchronisation therapy defibrillator (CRT-D). A CRT responder is defined as a person without chronic HF exacerbations during observation whose physical efficiency has improved owing to New York Heart Association (NYHA) class improvement ≥1. Results: A statistically significant difference was noted between responders and non-responders regarding creatinine level at the 3rd month (p=0.04) and, particularly, at the 12th month (p=0.02) of follow-up (100±23 vs 139±78 μmol/l). Moreover, there was a remarkable difference between both study groups with regard to GFR CKD-EPI (glomerular filtration rate (GFR) assessed using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula) at the 6th (p=0.03) and 12th month (p=0.01) of follow-up. The reference values for initial creatinine concentrations (101 μmol/l) as well as GFR CKD-EPI (63 ml/min/1.73m2 ) were empirically evaluated to predict favourable therapeutic CRT response. Conclusions: Predictive value of GFR CKD-EPI and creatinine concentration for a positive response to CRT were found relevant.

Abstract Background The natural history of primary sclerosing cholangitis (PSC) in children seems to differ from PSC in adults. However, studies on this matter have been limited by short follow-up periods and inconsistent classification of patients with autoimmune cholangitis (AIC) (or overlap syndrome). Consequently, it remains unclear if long-term outcomes are affected by the clinical phenotype. Aims The aims of this is study are to describe the long-term evolution of PSC and AIC in a pediatric cohort with extension of follow-up into adulthood and to evaluate the influence of phenotype on clinical outcomes. Methods This is a retrospective study of patients with AIC or PSC followed at CHU-Sainte-Justine, a pediatric referral center in Montreal. All charts between January 1998 and December 2019 were reviewed. Patients were classified as either AIC (duct disease on cholangiography with histological features of autoimmune hepatitis) or PSC (large or small duct disease on cholangiography and/or histology). Extension of follow-up after the age of 18 was done for patients followed at the Centre hospitalier de l’Université de Montréal. Clinical features at diagnosis, response to treatment at one year and liver-related outcomes were compared. Results 40 patients (27 PSC and 13 AIC) were followed for a median time of 71 months (range 2 to 347), with 52.5% followed into adulthood. 70% (28/40) had associated inflammatory bowel disease (IBD) (78% PSC vs 54% AIC; p=0.15). A similar proportion of patients had biopsy-proven significant fibrosis at diagnosis (45% PSC vs 67% AIC; p=0.23). Baseline liver tests were similar in both groups. At diagnosis, all patients were treated with ursodeoxycholic acid. Significantly more patients with AIC (77% AIC vs 30 % PSC; p=0.005) were initially treated with immunosuppressive drugs, without a significant difference in the use of Anti-TNF agents (0% AIC vs 15% PSC; p= 0.12). At one year, 55% (15/27) of patients in the PSC group had normal liver tests versus only 15% (2/13) in the AIC group (p=0.02). During follow-up, more liver-related events (cholangitis, liver transplant and cirrhosis) were reported in the AIC group (HR=3.7 (95% CI: 1.4–10), p=0.01). Abnormal liver tests at one year were a strong predictor of liver-related events during follow-up (HR=8.9(95% CI: 1.2–67.4), p=0.03), while having IBD was not (HR=0.48 (95% CI: 0.15–1.5), p=0.22). 5 patients required liver transplantation with no difference between both groups (8% CAI vs 15% CSP; p=0.53). Conclusions Pediatric patients with AIC and PSC show, at onset, similar stage of liver disease with comparable clinical and biochemical characteristics. However, patients with AIC receive more often immunosuppressive therapy and treatment response is less frequent. AIC is associated with more liver-related events and abnormal liver tests at one year are predictor of bad outcomes. Funding Agencies None
