#503 The influence of the degree of liver cell failure on the functional state of the kidneys in patients with liver cirrhosis

Abstract Background and Aims Studying the influence of the severity of liver cirrhosis on the functional ability of the kidneys in patients without concomitant diseases (without diabetes mellitus and hypertension). Method The study included 38 patients with liver cirrhosis who were treated in the gastroenterology department of the Republican Scientific and Practical Center for Therapy and Medical Rehabilitation in Tashkent. The average age of patients was 54 ± 3.4 (from 33 to 65). The examined patients were divided into two groups, depending on the degree of hepatic cellular failure (according to the Child-Pugh classification) and the development of ascitic syndrome. In group 1 Liver cirrhosis without ascites (P-P class A) the number of patients was 20. In group 2 Liver cirrhosis with ascites (P-P class B) the number of patients was 18. When examining patients, we used: Clinical blood test; blood chemistry; determination of electrolytes, creatinine; general urine analysis; glomerular filtration level; Functional renal reserve (defined as the increase in glomerular filtration expressed as a percentage after the administration of Dopamine at a dose of 2-3 μg/kg/min. To assess portal hypertension, all patients underwent ultrasound examination of the organs abdominal cavity and duplex scanning of portal system vessels. Results The examined patients were analyzed for the functional state of the kidneys and its relationship with the main parameters of portal hypertension and hepatic cell failure. Comparative characteristics of the main indicators of renal function significant differences in functional parameters were revealed depending on degree of hepatic cell failure. In the group of patients with cirrhosis with ascites, there was a significant decrease in renal GFR to 77.5 ± 1.4 ml/min, in contrast to the unchanged level of GFR in the group of patients with cirrhosis without ascites—99.3 ml/min. In patients with cirrhosis without ascites, the glomerular filtration rate increases by against the background of dopamine administration was 13.5 ± 4.7% (which corresponds to the norm), in contrast to patients in the second group, where the average Renal Functional Reserve was 8.4 ± 2.8%. Changes in renal function were also characterized by a decrease in Fractional Excretion of Sodium (FENa). The reduction in FENa in the group of patients with persistent ascites. During a detailed assessment of the RFR in patients of the first group, the RFR was below normal only in 2.6 ± 2.5%, while in the second group the number of patients with the decrease in the RFR was 69.7 ± 8.1%. Study of functional renal reserve in a group of patients with cirrhosis with ascites revealed unchanged this indicator in only 10 (30.3 ± 8%). U 19 (57.5 ± 8.6%) of patients in this group, the RFR was less than 10%, and in 12.2 ± 5.7% cases of RFR was below 5%, which indicated pronounced intraglomerular hypertension and the risk of developing resistant ascites. Conclusion The present study indicates that Renal Functional Reserve (RFR) in patients with liver cirrhosis reflects the speed of effective renal plasma flow. A decrease in FPR in Child-Pugh class A liver cirrhosis was detected in 2.6% of cases, with hepatic cell failure, Child-Pugh class B in 69.7%.

Clinical course of ascitic syndrome and acute kidney injury in the setting of nonselective beta‑blockers or endoscopic variceal ligation for primary prevention of bleeding in cirrhotic patients awaiting liver transplantation

Objective: to compare the effects of nonselective beta-blockers (NSBB) and endoscopic variceal ligation (EVL) on patient survival, ascites dynamics, and development of acute kidney injury (AKI) during primary prevention of bleeding from the esophageal varices and cardia in patients with decompensated cirrhosis on the liver transplant waiting list (LTWL). Materials and methods. A retrospective comparative study of the clinical data of patients with severe ascites and esophageal varices without a bleeding history at the time of their inclusion in the LTWL was performed. Group 1 patients (n = 84) were prescribed NSBB, alpha and beta-adrenoblockers in order to prevent bleeding and reduce progression of decompensated cirrhosis. Group 2 patients underwent EVL. Results. Demographic, laboratory and instrumental parameters of patients in the compared groups had no significant differences. In both groups, there were no significant differences between the indicators of severity of liver lesions (MELD-Na, Child–Turcotte–Pugh), frequency of severe ascites, frequency of varicose nodes grades 2–3. At follow-up, bleeding developed in 22 patients (13.25%) – 13 patients in the NSBB group and 9 patients in the EVL group (15.47% and 10.97%, respectively, p > 0.05). Patient survival was significantly higher in the EVL group than in the NSBB group. Incidence of refractory ascites, number of patients with grade 3 ascites, and AKI stages 2–3 in the NSBB group, were significantly higher (p < 0.05) than in the EVL group. MELD-Na was the independent predictor of mortality in the EVL group, while low mean arterial pressure (mAP) and presence of AKI were those for patients receiving NSBB. Conclusion. NSBB and EVL are effective methods of primary prevention of bleeding. Mortality rate, number of patients with refractory ascites and severe ascites, and number of patients with AKI stages 2–3 were higher in the NSBB group than in the EVL cohort. In EVL patients, the independent predictor of death was MELD-Na, while in NSBB patients, the independent predictors of mortality were low mAP and presence of AKI.

Chronic Liver Diseases and COVID-19: Database of General Hospital

Patients with chronic liver diseases (CLD) are at high risk of infection and severe COVID-19 (Corona Virus Disease).Aim: to create a database of patients with CLD, including an analysis of the frequency of detection of SARS-CoV-2 markers, the causes of hospitalization, an assessment of 30-day mortality in the presence of COVID-19 markers and in the absence of infection.Materials and methods. A one-time retrospective observational comparative study was conducted, the result of which was the creation of a database. 693 electronic case hystories of patients with CLD of various etiologies hospitalized in the V.M. Buyanov State Clinical Hospital for the period 01.04.2020–01.10.2021 were analyzed. Th e analysis included the following parameters: gender, age, etiology of the disease, reasons for hospitalization, the presence of ribonucleic acid (RNA) SARS-CoV-2 in a smear of the nasal mucosa and oropharynx, antibodies to SARS-CoV-2 immunoglobulins of classes M, G (IgM, IgG), the outcome of the disease (30-day mortality).Results. Markers of past new coronavirus infection (IgG) were detected in 268 (38,7 %), SARS-CoV-2 RNA was detected in 67 (9,7 %). Th e analysis of the causes of hospitalization revealed the predominance of edematous ascitic syndrome (64,5 %), an increase in hepatic encephalopathy (31,6 %) and an increase in the number of cases of portal vein thrombosis (PVT) (8,9 %). When assessing the 30-day mortality, signifi cant diff erences were found in patients with Alcohol-related liver disease (ARLD), chronic viral hepatitis in the presence of COVID-19 markers and in cases of their absence.Conclusion. SARSCoV-2 markers were found in 335 (48,3 %) of patients with CLD. Th e main reason for hospitalization is the appearance /increase of edematous ascitic syndrome, including due to PVT. 30-day mortality in the postcovid period is signifi cantly higher (р = 0,0246) in ARLD compared with patients without COVID-19 (218 (34,9 %) и 300 (25,3 %), respectively, р = 0,0246).

Time series evaluation of condemnation at poultry slaughterhouses enable to export in Southeastern Brazil (2009-2019): a tool for optimizing resources in the poultry production chain.

Even with the technological advances in management, health and genetics applied to poultry farming worldwide, there is still a high rate of carcasses condemnation at slaughterhouses, which result in losses for the poultry production chain. Thus, this work aimed to evaluate the condemnation occurrence index (COI) and adjusted seasonal index (ASI) of poultry (turkey, griller, and heavy chicken) between 2009 and 2019, in a slaughterhouse enable to export in southeastern Brazil. Data were obtained from official spreadsheets from the Brazilian Federal Inspection Service (FIS) and used to calculate the COI, correlation analysis between the main causes of condemnation, and ASI assessments throughout the year. Seven percent (55,594,318) of the poultry carcasses were condemned (partial or total), and the most frequent causes, contamination, and contusion/traumatic injury, amounted to 63.5% of the total condemnation. There was a trend of increasing condemnation throughout the time series evaluated, with COI varying between 45,282-149,809 condemnations per 1,000,000 poultry slaughtered. Considering the ASI, it was identified that for ascitic syndrome, July has a higher index value (1.63) than the months between January-June (P < 0.05). The main causes of condemnation were contamination and contusion/traumatic injury, both technological causes. ASI showed that in July there is a greater carcasses condemnation due to ascitic syndrome than in the months between January and June. The variations observed in the ASIs can provide subsidies for preventive measures and optimization of human and financial resources, generating positive impacts on food safety, productivity, and profitability of the sector.

Histological Identification and Quantification of Eosinophils and Ascites in Leghorn Chickens Treated with High Oral Concentrations of NaCl-Pilot Study.

The purpose of this pilot study was to determine the role played by eosinophils in NaCl poisoning and right cardiac hypertrophy (ascitic syndrome) in Leghorn chickens, as well as the histological findings in the central nervous system (CNS), liver, and kidney. Moreover, the hypertrophy of the right ventricle index (HRVI) as an indicator of ascites was evaluated. Male SPF Leghorn birds at 28 days of age were submitted to two experiments. Food and water (FW) experiment: birds were treated with food plus 3.3% NaCl for the next 27 days and 1% NaCl in their drinking water from days 22 to 27. Water experiment (W): birds were treated with 1% NaCl in their drinking water for 5 days. In both experiments, the chickens exhibited loss of appetite, diuresis, and watery, green diarrhea during treatment days; at 24–27 td-FW and experiment W, the birds showed nervous signology (prostration, running movements, tremors, and comatose state). In the leukogram at 28 td-FW, an increase (p < 0.05) in heterophiles and basophils was observed. CNS eosinophilia was not observed in birds intoxicated with NaCl, though they did present demyelination in the brain and spinal cord, hepatic degeneration, mesangial proliferative glomerulopathy, and acute proximal renotubular necrosis.

Use of laparocentesis in the treatment of ascites in patients with liver cirrhosis

Ascites occurs in about 60 % of patients with cirrhosis within 10 years of diagnosis. Laparocentesis is the preferred first-line therapy in patients with cirrhosis and massive tense ascites, allowing more than 5–6 liters of ascitic fluid to be removed at one time. The search for informative prognostic factors and the development of a method for predicting unfavorable outcomes of repeated laparocenteses in patients with ascites are relevant to timely refer this contingent of patients to perform TIPS.The purpose of the study was to develop and evaluate the diagnostic significance of a model for determining the probability of unfavorable outcomes of laparocentesis in patients with ascites on the background of liver cirrhosis.The results of treatment of 99 patients with the ascitic syndrome associated with intrahepatic portal hypertension were studied. The multiple regression analysis using the binary response logit model was carried out to calculate the prediction models. The analysis of the treatment results of patients with liver cirrhosis and ascites by the laparocentesis method revealed a number of factors that influence the onset of an unfavorable outcome. 2 models with the inclusion of initial variables are the most promising for forecasting. Model A includes: patient weight, serum-ascites total protein gradient, hyponatremia; model B: MELD-Na score, serum-ascitic total protein gradient, patient weight. The developed prediction method is highly informative, effective, easily applicable, and can be widely used in clinical practice.The ability to predict an unfavorable outcome in patients with portal hypertension and ascites after laparocentesis allows for a personalized approach in the process of timely selection of more effective, but also more expensive treatment methods, such as TIPS, which will help us to increase the therapy effectiveness and the survival of this cohort of patients.

Особливості клінічного перебігу хвороби Вільсона в дітей

Purpose — to discover peculiarities of Wilson disease course in children dependently on the variant of liver affection. Materials and methods. Anamnesis of the disease and clinical and paraclinical peculiarities of the course of the disease with consideration of liver affection severity have been studied in 50 children aged 5–17 years. Results. It was estimated that in 52% of children the disease had a form of chronic hepatitis with minimal clinical symptoms, 44% of patients had liver cirrhosis with predominant signs of edematous and ascitic syndrome and 4% had fulminant hepatitis in a debut of the disease. Complicated family anamnesis was detected in 4% of patients. Syndrome of cytolysis predominated in patients with liver damage in the form of chronic hepatitis (р&lt;0.05). Typical biochemical changes in cirrhotic patients were hepatocellular insufficiency with hypoalbuminemia and coagulopathy, hyperbilirubinemia and minimal hypertransaminasemia (р&lt;0.05). Children with cirrhosis in contrast to patients with chronic hepatitis had reliably lower serum ceruloplasmin concentration and reliably higher excretion of copper with urine. Specific for Wilson disease Kayser—Fleischer rings were found out in 36% of patients only. Conclusions. Wilson's disease in children is characterized by progressing course in the form of either chronic hepatitis or liver cirrhosis or, rarely, fulminant hepatitis. Clinical and paraclinical symptoms of the disease are estimated by the severity of liver affection and vary from a course with minimal symptoms in patients with chronic hepatitis to edematous and ascitic syndrome and hepatocellular insufficiency in patients with cirrhosis and fulminant hepatitis. The research was carried out in accordance with the principles of the Helsinki declaration. The study protocol was approved by the Local Ethics Committee of all participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors. Key words: Wilson's disease, children, chronic hepatitis, liver cirrhosis, course of the disease.

Time series evaluation of ascitic syndrome condemnation at poultry abattoirs under Federal Inspection Service of Brazil (2010-2019)

ABSTRACT: Over the last decade, Brazil registered a 10.56% increase in the number of poultry slaughtered in establishments registered under the “Serviço de Inspeção Federal” (SIF - Federal Inspection Service), as a result of technological advances in management, health and genetics applied to national aviculture. At slaughter, during post-mortem inspection, carcasses can be totally or partially condemned for various reasons, including ascitic syndrome. This syndrome has economic implications for the industry, in addition to being a problem for the health and welfare of poultry. The objective of this work was to evaluate the historical series (2010-2019) of partial and total condemnations of poultry carcasses due to ascitic syndrome in slaughterhouses registered under the SIF and located in the main poultry-producing states. Through official data, the condemnation occurrence index (COI) and the adjusted seasonal index (ASI) were calculated. The condemnation rate was 1,140 carcasses condemned, totally or partially, for ascitic syndrome for every 1,000,000 poultry slaughtered. The smallest and largest COIs were found in São Paulo (February 2010) and in Goiás (January 2017), respectively. The occurrence of condemnations for this syndrome was cyclical throughout the historical series, showing peaks of condemnation in all years evaluated, with the highest ASIs in July, August and September, and with rates varying between 1.24 and 1.54 in these months. Considering the period of pre-slaughter housing, the highest ASIs coincide with the coldest period of the year (May to August) for all analyzed states. The results show that ascitic syndrome is a growing problem in Brazil, with greater occurrence during the coldest months of the year, having a negative impact on animal health and the profitability of producers and industries in the poultry production chain.

Mastocytosis in Adults: A Retrospective Analysis of the Clinical Course and Treatment of 58 Patients

Background. Mastocytosis is a disease caused by proliferation and accumulation of clonal mast cells in one or more organs. It is often associated with other hematological tumors. Aggressive forms of mastocytosis (AFM) require specific therapy. In non-aggressive forms of mastocytosis (NFM) symptomatic treatment is needed. Aim. To analyze the clinical course and treatment outcomes in different forms of adult mastocytosis. Materials &amp; Methods. The retrospective analysis was based on the records of patients who received in-person and distance consultation within the period from 11/2008 to 11/2020. The analysis of complaints in disease onset and over time was carried out using questionnaires. NFM patients received symptomatic treatment with antihistamines. To all AFM patients chemotherapy was administered. Results. The analysis includes the data of 58 patients: 39 (67.2 %) women and 18 (32.8 %) men. The median age was 40 years (range 18-79 years), the median age on diagnosis was 39 years (range 1-79 years). In all patients skin rashes were reported. The median age of the first skin manifestations was 25 years (range 0.1-70 years). In-person monitoring was conducted in 34 (58.6 %) patients, 24 (41.4 %) patients received distance consultations. Median follow-up was 56.5 months (range 3-564 months). In 8 (13.7 %) patients mastocytosis was diagnosed in childhood with the median of 9 years (range 0-15 years). The diagnosis was morphologically confirmed in 46 (79.3 %) patients. Main complaints included pruritus (67.2 %), edema and erythema response to various irritants (62 %). In 45 (77.5 %) patients NFMs were reported. The regular symptomatic treatment of 78.8 % of NFM patients consisted only of antihistamines (57.9 %), and 2 (4.4 %) patients noted poor disease symptom control. One (2.2 %) patient died of associated chronic myelomonocytic leukemia. None of NFM patients required cytoreductive treatment. AFMs were diagnosed in 13 (22.4 %) patients, 5 (38.4 %) out of them had mast cell leukemia. The indications for starting chemotherapy were cytopenia (n = 3; 23 %), extensive osteolysis (n = 7; 53.8 %), ascitic syndrome with portal hypertension (n = 6; 46.1 %). Overall survival of AFM patients was 84.6 % (n = 11) with median follow-up of 80 months (range 12-131 months). Conclusion. NFM prognosis is favorable. Antihistamines are effective in relieving complaints of most patients. Cytostatic treatment of AFM in some patients provides long-lasting antitumor response.

Assessment of external risk factors of hepatocellular cancer development and markers of genetic predisposition to its development in the ethnic group of yakut - men

To establish the main external and genetically determined risk factors for the development of hepatocellular cancer in the ethnic group of male Yakuts living in the Republic of Sakha (Yakutia) [RS (Y)] in the epidemiologically unfavorable conditions of the incidence of viral hepatitis. A total of 97 male Yakuts were examined, including 44 people diagnosed with hepatocellular cancer and 53 people diagnosed with chronic viral hepatitis. HCC risk factors were identified by analyzing medical records and questioning patients. In the experimental and control groups, genetic studies of single nucleotide polymorphisms of genes mapped on the X-chromosome and involved in the activation of antiviral immunity along the TLR7 signaling pathway were performed. In 100% of patients with hepatocellular cancer, infection with hepatitis B, C, D viruses or co - infection with these agents was detected. Every fourth patient with HCC in the RS (Y) was infected with hepatitis D. The course of hepatocellular cancer associated with HDV was characterized by rapid progression of liver cirrhosis, development of portal hypertension, bleeding from varicose veins of the stomach and esophagus (36.4%) and edematous ascitic syndrome (63.6%). In addition to viral agents, additional risk factors for liver cancer were identified, such as alcohol abuse, overweight, diabetes mellitus, and smoking. Among the studied variation sites of genes localized on the X-chromosome and encoding the reaction of innate antiviral immunity, no genetic marker was found with a sufficient degree of confidence determining the likelihood of hepatocellular cancer developing. The high incidence of hepatocellular carcinoma of the male population in the RS (Y) is due to the widespread prevalence of parenteral viral hepatitis, especially viral hepatitis D. Due to the introduction of mass vaccination of the population against hepatitis B in the Russian Federation in the foreseeable future in the RS (Y) we should see a decrease in the proportion of hepatocellular cancer associated with hepatitis B and D viruses, and therefore the focus should be on the treatment and prevention of hepatitis C virus and non - infectious risk factors.

Autosomal Dominant Polycystic Kidney Disease with Hepatic Cysts Complications in a Hemodialysis Patient: A Case Report

Abstract Background: Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited kidney disease in humans. It is a multisystemic disorder characterized by progressive cystic dilatation of both kidneys, with variable extrarenal manifestations in the gastrointestinal tract (hepatic cysts), cardiovascular system, reproductive organs and brain. An important issue of patients with hepatorenal cystic disease is the fact that complications can arise due to the growing of the cysts: local kidney complications (intracystic infection, intracystic hemorrhage) and local liver complications (portal hypertension as a result of portal vein compression by cysts, bile duct compression, ruptures and bleedings of the cysts, obstruction of the liver veins). Objective: The main purpose of our case presentation is to emphasize the fact that ADPKD can be an aggressive disease with multiple complications, which requires an early diagnosis in order to properly avoid possible complications. Material and Method: We present the case of a 61 years old male, known with polycystic hepatorenal disease, chronic kidney disease (CKD) in chronic hemodialysis since 2010, renal hypertension, hypertensive cardiomyopathy, renal anemia and stage 1 chronic lymphatic leukemia. The patient was diagnosed with hepatorenal polycystic disease 20 years ago and 9 years ago he started undergoing renal replacement therapy by hemodialysis. Three months ago, the patient presented a suddenly installed ascitic syndrome for which an MRI was performed. The imagistic investigation revealed multiple kidney and liver cysts, with secondary compression of the portal vein and a tumoral mass that may suggest an adenocarcinoma. Results: The investigations performed confirm the diagnosis of portal hypertension secondary to compression due to cystic formations. Conclusions: Hepatorenal polycystic disease has numerous clinical variations, so it needs to be followed in a multidisciplinary way with rapid therapeutic measures to prevent complications. Further investigations are needed when dealing with suspicious cystic formations with an uncertain substrate.

ESTIMATION OF METASTATIC NEOGENESIS IN ASCITIC EXUDATE BY AN AUTOMATED ANALYSIS OF BIOLOGICAL LIQUIDS

The aimis to carry out an automated analysis of biological liquids for the estimation of metastatic neogenesis in ascitic exudates.Materials and methods.A retrospective analysis of 40 case histories of patients with the ascitic syndrome of non-tumour (cirrhotic) and tumour genesis was performed. Traditional cytology was accompanied by an automated analysis of exudative fluids. The final diagnosis was verified using instrumental and pathomorphological methods. The processing of statistical data included an assessment of the intergroup difference significance.Results.Compared with cirrhotic ascites, the following parameters of the automated analysis of biological fluids are found to be statistically significant (p30% in the atypical cell screening system has been established. In the absence of an acute inflammatory reaction, the presence of eosinophils in the exudate should be interpreted as an indirect marker of a tumour process. According to the data obtained, the content of neutrophils, lymphocytes and monocytes in ascitic fluids does not depend on the nature of the process (p&gt;0.05).Conclusion.The diagnostic capabilities of automated analysis of ascitic fluids are analysed. In the system of differential diagnosis of tumour and non-tumour processes, the following parameters are established to possess the greatest informative value: TCN, HF, and the presence of eosinophils (EO).Conflict of interest: the authors declare no conflict of interest.

Results of portosystemic shunting in patients with hepatic cirrhosis and ascites syndrome

Purpose. Assess the results of portal systemic shunting (PSSh) in patients with liver cirrhosis (LC) with ascitic syndrome.&#x0D; Materials and methods. Analyse the results of PSSh in 556 patients operated a year from 2000 to 2015. The basis of the analysis taken all the features related to the development and progression of ascitic syndrome. Depending on the shunt type, research conducted with most frequently performed shunts groups.&#x0D; Results. Initial decompensated cirrhosis by edema-ascites syndrome significantly increases the risk of specific complications such as hepatic insufficiency from 6.9% to 13.5%, hepatic encephalopathy from 12.1% to 16.2% and increase in ascites from 7.2% to 16.2%, and the mortality rate from 2.1% to 3.8%. The main cause of early mortality after PSSh is a risk of thrombosis of the anastomosis with recurrent bleeding, whereas other specific complications, conservative measures allow neutralizing the difference in the index of satisfactory results of the operation (96.2% — in the group with ascites before PSSh against; 97.9% — in the group without ascites). Quantitative and qualitative analysis of ascites showed that in the coming period after the shunt (3-5 days) the development of this complication depends on the type of bypass surgery, so when the distal splenorenal shunts (DSRS) production of ascites significantly increased (P &lt;0,01), while total protein component fluid significantly (P &lt;0,02) higher than in patients in ascites with central bypass type. This fact is due to the formation of the selective type of bypass on the background of DSRS, and the growth of ascites does not depend on the presence of complications before surgery, indicating that the impact factor of the severity of portal hypertension and therefore the adequacy of decompression of the portal vein system, against which a decrease in blood albumin fraction and increase it in ascites (R2 = 0,57) may be indicative of a high residual portal pressure.&#x0D; Conclusion. In patients with cirrhosis after PSSh in 70.2% of cases of decompensation of ascites syndrome is caused directly with cirrhotic process and the growth of functional impairment of hepatocytes, the remaining 29.8% of cases, the formation of the complications associated with the progression of PH syndrome on the background of anastomotic thrombosis.

Relato de caso: Síndrome ascítica em frangos de corte durante o outono na região noroeste do Estado de São Paulo

This research aims at reporting the cases of Ascitic Syndrome in chickens at Techinician School (ETEC) - Andradina, located in the northwest of the state of São Paulo, to better understand such disorder which is so common in modern chicken raising, mainly throughout the seasons of the year when there is great temperature variation, wind increase and consequently, death of the lots. In this report, there were findings of prostrated birds, bristling legs, abdominal distention, bluish color and growth impairment. In relation to the necropsies, the most common findings were: yellowish liquid with jelly material, congested and irregular liver, right cardiac dilation. The syndrome was responsible for 81.81% of mortality in the lot.

Spontaneous Occurrence of Ascites in Commercial Broiler Flock and Its Management

The present study was carried out on 100 broiler chicks that were reared in an organized poultry farm. From the above mentioned flock 28 birds died of unknown etiology. The clinical signs and post mortem changes were studied. Most of clinical signs were non-specific except a typical frog sitting posture with a backward leg extension noticed in all birds prior to death. Necropsy revealed accumulation of straw coloured fluid in the abdominal cavity which confirmed ascitic syndrome. After the diagnosis, effective control measures such as immediate withdrawal and replacement of leftover feed and provision of proper ventilation to the unaffected birds stopped further mortality in the flock.

Primary granulocytic sarcoma of the peritoneum: a case report and literature review

Granulocytic sarcoma is a rare tumor composed of immature granulocytic cells. Prognosis is poor. The periosteum is preferentially involved. A peritoneum localization is unusual. We report the case of a 20 years old man without particular previous pathologies, which brutally presented an ascitic syndrome in a context of health impairment state. The laparoscopy showes many white nodules on all the peritoneum. The histologic examination of one of these nodules showed granulocytic sarcoma. The blood and bone marrow cell count are without any anomaly. The treatment consisted of a standard acute myeloid leukaemia's chemotherapy with very good evolution. The rarity of peritoneal chloroma causes a diagnostic problem, especially in the absence of hematologic abnormalities. It must be mentioned in the presence of peritoneal nodules even if the blood count and bone marrow are normal.

Condenações por síndrome ascítica em frangos abatidos sob inspeção federal entre 2002 e 2006 no Estado do Rio Grande do Sul, Brasil

A ocorrência de condenação total de carcaças de frangos devido à síndrome ascítica (SA) em matadouros sob inspeção federal, no Estado do Rio Grande do Sul, alcançou a soma de 1.605.439 unidades no período compreendido entre 2002 e 2006, chegando a 8,19% do total de condenações do período, sem aproveitamento parcial, conforme dados obtidos junto ao Ministério da Agricultura Pecuária e Abastecimento (MAPA). Este trabalho teve como objetivos discutir e apresentar as causas e formas de controle da SA, bem como avaliar a evolução da ocorrência deste transtorno metabólico, uma vez que, em 2002, a síndrome ascítica representou 6,4% do total de condenações, crescendo gradativamente até 2006, quando a ascite representou, até o mês de novembro, 9,6% das condenações de carcaça total. A regressão linear apresentou uma forte correlação (0.92), demonstrando que os casos de condenações por ascite estão aumentando gradualmente. Os prejuízos advindos destas condenações, durante o período avaliado, geram valores na ordem de R$ 3,6 milhões, o equivalente a US$1,7 milhões. Esses dados demonstram a importância de maior controle e do monitoramento da enfermidade para o setor avícola.

Edad de reproductora pesada y peso del huevo sobre los parámetros productivos y la incidencia del síndrome ascítico en la progenie

Two experiments were carried out with broilers with the object of assessing productive performance and susceptibility to ascitic syndrome (AS) in progeny of heavy breeding hens of diverse age and egg weight. In the first experiment, 1,500 broilers coming from 35, 44 and 53 weeks old hens, in the second experiment 1,500 broilers that came from differing egg weights (75, 66, 58 g), were used. Results referring to hens', age showed significant differences (P0.05) for feed conversion and for general and AS mortality. These test confirm that broilers that come from older breeding hens enjoy a better productive performance and that, most probably eggshell thickness and albumin quality play a role in gaseous interchange, thus contributing to a higher ascitic syndrome susceptibility.

Incidência de Doenças Metabólicas em Frangos de Corte no Sul do Brasil e Uso do Perfil Bioquímico Sanguíneo para o seu Estudo

Esse trabalho foi realizado em granjas de frangos de corte localizadas no estado do Paraná (sul do Brasil). Foram consideradas 450 granjas, perfazendo uma população total de 4,5 milhões de frangos em um período de 6 meses, durante o qual foram registradas a mortalidade total e as mortes devidas a síndromes metabólicas relacionadas com síndrome ascítica e síndrome de morte súbita, entre a 1ª e a 7ª semana de vida. A mortalidade total foi de 4,8%. Desse total, 12,9% foram registrados como mortos compatíveis com síndrome ascítica e 26,4% compatíveis com síndrome de morte súbita. O pico de mortalidade esteve na 5ª semana de idade para a síndrome ascítica e na 6ª semana para a síndrome de morte súbita. Discute-se que a síndrome de morte súbita pode estar incluindo morte súbita por stress calórico. Os perfis bioquímicos do soro sangüíneo mostraram que aves acometidas por sinais compatíveis com síndrome de morte súbita se caracterizaram por hiperproteinemia, hiperlipidemia, aumentos de ácido úrico, fósforo e magnésio. Nesse caso, o perfil revelou também um choque hipovolémico, além de acidose metabólica e distúrbios no metabolismo dos lipídios. O perfil dos frangos acometidos por sinais compatíveis com síndrome ascítica mostrou depressão do metabolismo energético, evidenciado por diminuição dos níveis de glicose, colesterol e triglicerídeos, além de hipoproteinemia e hipocalcemia.

Liver capsule thickening characterized by mesothelial cell proliferation with vascularization in broilers ascites syndrome

Thickened liver serosal membranes in 24 8-week-old male young broiler chickens with the ascitic syndrome were pathologically examined. Gross changes included inflammation of liver capsules (15/24 cases), right ventricular dilation (24/24 cases), pericarditis (5/24 cases), peritonitis (9/24 cases) and air sacculitis (7/24 cases). Histopathology revealed liver capsule thickening and focal hepatitis in all 24 cases, peri- and epi-carditis in 19 and myocarditis 11 cases. The thickened liver capsules consisted of spindle shaped-cells which reacted with anti-keratin rabbit serum and anti-vimentin monoclonal antibody, and formed cysts of varying size containing clear yellow fluid as ascitic fluid. The volume of sub-capsular fluid may have been responsible for the development of the cysts. The spindle-shaped cells were located perpendicular to the surface with thin bridges from the serosa together with a little collagen and vascularization. These changes were not observed in other serosal membranes in abdominal air sac or pericardium. We have therefore shown that the liver capsule thickening in the broilers ascites syndrome is characterized by mesothelial cell proliferation with vascularization.
