RESUMEN

Background & objectives: Serum alanine aminotransferase (ALT) level is most commonly used as a marker for the assessment of various liver diseases. Currently upper limits of normal for aspartate aminotransferase (AST) or ALT levels used are based on the western literature. This study was conducted to determine the ALT and AST levels in healthy blood donors from western India and to determine the relation with body mass index (BMI) and waist-to-hip ratio (WHR). Methods: A total of 5077 voluntary blood donors were selected with strict routine inclusion and exclusion criteria. Weight, height, BMI and WHR were determined along with AST and ALT levels. BMI and WHR were correlated with liver enzymes. Results: Of the 5077 donors, 160 were excluded due to positive serological results. In the remaining 4917 individuals, 4643 (94.4%) were males and 274 (5.6%) were females. Majority 3024 (61.5%) showed BMI more than 23 kg/m2. WHR > 0.85 and 0.80 was found in 4046 (87.0%) males and 250 (91.2%) females. Mean AST and ALT levels in males were 23.4 ± 9.9 IU/l and 27.0 ± 17.3 IU/l and in females 19.1 ± 9.8 IU/l and 17.7 ± 11.2 IU/l, respectively. With increase in BMI, there was a significant increase in AST and ALT levels. Similar increase was also seen with WHR. Interpretation & conclusions: Majority of voluntary blood donors showed high BMI and WHR which was directly related to AST and ALT levels. This study highlights the magnitude of obesity in general healthy population of western India and a need to revise the current normal limits of serum ALT.

RESUMEN

Introduction: The diagnosis of ulcerative colitis is based on combination of clinical, endoscopic and pathological findings. However cases have been reported showing atypical endoscopic and histological features in ulcerative colitis. Hence the objective of this study was to determine the atypical features of new onset ulcerative colitis in adult population. Methods: A total 110 newly diagnosed cases of ulcerative colitis were enrolled in the study over a period of five years. The diagnosis of ulcerative colitis was made by correlating clinical, endoscopic and histological features. Biopsies from representative areas were processed routinely. Endoscopic and histological evaluation was carried out for atypical features. Results: Majority of the patients (75.4%) were between 21-50 years of age with male to female ratio of 2.2:1. A significant number of patients showed atypical endoscopic findings in the form of rectal sparing in 12 (10.9%) and skip lesions in 24 (21.8%) patients. Atypical features noted on histology included normal surface epithelium in 8 (7.3%), predominant polymorphs in 42 (38%), predominant eosinophils in 7 (6.3%), normal crypt architecture in 1 (0.9%) and well preserved goblet cells in 30 (28%) cases. Conclusion: A significant number of patients with new onset ulcerative colitis showed atypical pattern of disease endoscopically as well as histologically. Pathologists should be aware of these atypical findings in cases of ulcerative colitis so as to avoid misdiagnosis.

RESUMEN

An eight-month-old female, delivered to consanguineous parents, presented with acute liver cell failure. Her investigations showed progressive cholestatic jaundice, high liver enzymes and high gamma-glutamyl transferase. Hepatitis and inborn errors of metabolism were excluded. The liver biopsy showed a prominent parenchymal bile stasis without features of bile obstruction or paucity of bile ducts. These findings wee suggestive of Byler disease or progressive familial intra hepatic cholestasis type III (PFIC III) which begins in infancy and usually progresses to cirrhosis and hepatic failure in the first few years of life.

RESUMEN

Intestinal metastasis from lung primary is very uncommon and seen at the terminal stage of the disease. Clinically, patients present as perforation or bleeding and rarely as intussusception. We report the case of a 78-year-old man who came with sudden onset of abdominal complaints of four to five days duration. A computerized tomography (CT) - scan abdomen showed mural thickening of short loop of jejunum with ileoileal intussusception. Resection-anastomosis revealed two separate nodules in the small intestine. The patient, a diagnosed case of primary carcinoma of lung seven months ago, had been treated with one cycle of chemotherapy. Histopathology of the small intestinal nodules showed features of adenocarcinoma consistent with the known primary lung cancer. We present this case to arouse a clinical suspicion of intestinal metastasis in known cases of primary lung cancer presenting with the sudden onset of abdominal complaints. Early diagnosis and management improves the survival of these patients.

RESUMEN

Introduction: Gastrointestinal tuberculosis (GITB) is a great mimicker and it is often difficult to distinguish GITB from other inflammatory lesions of the intestine. Aim: This study was carried out with the objective of analysing the entire morphological spectrum of GITB. Methods: A total of 110 diagnosed cases of GITB were included in the study. The diagnosis was based on the presence of acid-fast bacilli (AFB) on histology, caseating or non-caseating epithelioid cell granulomas (ECGs), evidence of tuberculosis at other extraintestinal sites, and all of these along with a complete response to anti-tuberculous treatment (ATT). Results: The mean age was 30.9 years with M:F ratio of 1:1. On gross examination, apart from typical tuberculous lesions in the form of transverse ulcers, strictures, hyperplastic lesions and serosal tubercles, intestinal perforation (32.6%) was seen with higher frequency and ischemic bowel was also identified (7.3%). Varied morphological patterns of ECGs in the form of caseating, non-caseating, confluent, discrete and even suppurative granulomas were identified on histopathology. An important finding was the co-existence of different types of granulomas within the same case. In a significant number of cases (44.5%) granulomas were seen in a submucosal location. The predominant type of inflammation seen in the lamina propria was lymphoplasmacytic in 85.5% cases. Conclusion: Pathologists should be aware of the entire spectrum of gross and histopathological features of GITB, so as to avoid misdiagnosis.

RESUMEN

BACKGROUND: Angiogenesis has been well documented in hepatocellular carcinoma (HCC). As liver cirrhosis is considered preneoplastic condition, the aim of this study was to evaluate the process of angiogenesis using CD 34 as an endothelial cell marker in normal liver, cirrhosis and HCC. MATERIALS AND METHODS: A total of 111 cases were included in this study, which consisted of 30 cases each of normal liver and cirrhosis that were all autopsy cases. Twenty-one cases of HCC included 10 autopsy specimens, nine surgically resected specimens and two liver biopsies. Remaining were 30 cases of metastasis to the liver, which included 20 autopsy specimens, one surgically resected specimen and nine liver biopsies. The patients were between the age range from 17 to 80 years with 70 males and 11 females. Paraffin-embedded liver sections of all these cases were stained routinely by hematoxylin-eosin stain, while immunohistochemistry for CD 34 was performed for expression of endothelial cells. The positivity of CD 34 staining was evaluated by counting in 10 high-power field, grading was done from 0 to 4 and compared between normal liver, cirrhosis and HCC and metastasis. RESULTS: CD 34 was positive in 16/30 (53.3%) cases of cirrhosis, 18/21 (85%) cases of HCC and 26 (86.6%) of metastasis to the liver. None of the normal liver showed any positivity. Grade 3 to 4 positivity was seen in 4/16 (25%) and 13/18 (72%) cases of cirrhosis and HCC, respectively. Amongst these, 10 were moderately differentiated, one well differentiated and rest two were fibrolamellar and sarcomatoid variants of HCC. CONCLUSION: Over expression of endothelial cell marker CD 34 with gradual progression was found from normal liver to cirrhosis to HCC and metastasis. Understanding of this process of angiogenesis might help in the design of efficient and safe antiangiogenic therapy for these liver disorders.

RESUMEN

Tuberculous involvement of liver as a part of disseminated tuberculosis is seen in up to 50-80% cases, but localized hepatobiliary tuberculosis (HBTB) is uncommonly described. During 6 years, a total of 280 consecutive patients with TB were evaluated prospectively for the presence and etiology of liver involvement. Cases with miliary TB or immunosuppression and cases receiving anti-tuberculosis drugs prior to presentation to our unit were excluded (38 cases). Details of clinical, biochemical and imaging findings and histology/microbiology were noted. Of 242 included cases, 38 patients (15.7%; age 38.1 +/- 12.5 years; sex ratio 2.5:1) had HBTB, whereas 20 patients (9%; age 39.3 +/- 16.3 years; sex ratio 2.1:1) had other liver diseases. Diagnosis of HBTB was based on caseating granuloma on histology (18/23 procedures), positive smear/culture for acid-fast bacilli (21/39 procedures) and positive polymerase chain reaction for Mycobacterium tuberculosis (28/29 procedures) when diagnostic procedures were guided by imaging results. Thirty-eight cases with HBTB were classified as follows [patients (n), (%)]: (A) hepatic TB [20 (52.6%)]: (1) granulomatous hepatitis - 10 (26.3%), (2) liver abscesses or pseudotumors - 10 (26.3%) and (3) calcified hepatic granuloma - 0 (0%); (B) biliary TB [15 (39.4%)]: (1) biliary strictures - 2 (5.2%), (2) gall bladder involvement - 1 (2.6%) and (3) biliary obstruction due to lymph node masses - 12 (31.5%); (C) mixed variety [3 (7.8%)]: (1) simultaneous granulomatous hepatitis and biliary stricture - 1 (2.6%) and (2) simultaneous lymph node involvement and calcified hepatic granuloma - 2 (5.2%). All the cases responded well to standard anti-tuberculosis therapy. HBTB forms an important subgroup in TB cases. It requires a combination of imaging, histological and microbiological procedures to define the diagnosis. HBTB responds well to treatment.

RESUMEN

Atypical stromal cells have been reported in inflammatory lesions of the gastrointestinal tract. We report a case of ulcerative colitis with pseudopolyps, histology of which showed bizarre stromal cells. These atypical stromal cells simulate malignant cells and pose a diagnostic problem for surgical pathologists. It is therefore important to recognize these benign stromal cells as reactive thereby reducing unnecessary surgery.

RESUMEN

OBJECTIVE: To study the spectrum of histopathological changes in the liver in cases of tuberculosis. MATERIALS & METHODS: This is an autopsy study consisting of 150 adult cases of tuberculosis over a period of 3 years. The diagnosis of tuberculosis was made on the basis of caseating granulomas or acid fast bacilli in the tissue. Cases showing only healed foci of tuberculosis at autopsy were excluded. Clinical details of all cases were obtained from hospital records. At autopsy, gross examination was done meticulously with special emphasis on the liver and extrahepatic biliary tree. Sections from the liver were processed routinely and histopathological findings were analyzed in detail. RESULTS: Patients were between 21 to 60 years of age with a male: female ratio of 2.1:1. Fever was the commonest symptom (62%). On gross examination, at autopsy, pulmonary and extrapulmonary tuberculosis was seen in 79 (52.6%) and 71 (47.4%) cases respectively. Liver involvement was mainly secondary except in one case. The extrahepatic biliary tree was involved in 18 cases, in the form of external compression of the common bile duct by a group of enlarged caseating, matted lymph nodes. The spectrum of histopathological changes of the liver showed epitheloid cell granulomas in 63 (42%), fatty changes in 49 (32.6%), inflammation in 60 (40%), sinusoidal congestion in 48 (32%) and fibrosis in 24 (16%) cases. Of the 63 cases of liver granulomas, 12 (19%) were cases of extensive pulmonary tuberculosis and the remaining were extrapulmonary tuberculosis. Granulomas were caseating in 58.7%, noncaseating in 23.8% and atypical in 17.5% cases. Fatty change ranged from mild to severe. Inflammation was mainly mild to moderate. Stage I and II fibrosis was seen in 13 (8.6%) and stage III and IV in 11 (7.3%) cases. On comparing the granuloma and non-granuloma cases histological features, it was found that fatty changes and inflammation were more with granuloma formation but there was no difference in the degree of fibrosis in the two groups. CONCLUSION: Liver involvement was mainly in the form of secondary tuberculosis. On histopathology, epitheloid cell granulomas were seen in 42% cases, other changes were non-specific. Significant fibrosis was seen in 7.3% cases however the finding of tuberculosis as a cause of significant fibrosis was not consistent.

RESUMEN

Cystic lymphangioma is an uncommon mesenteric tumor usually reported in children. We report a case of 14 year old female who presented with dull aching abdominal pain. At laparotomy a cystic tumor was found in mesentery, which was attached to bowel loops. The histopathology examination showed features of cystic lymphangioma. Although pre-operative diagnosis is usually possible on CT or MRI, confirmatory diagnosis of this lesion requires laparotomy followed by histopathology.

RESUMEN

Overlap syndrome in Autoimmune liver disease is not unusual but the switch over from one type of autoimmune liver disease to another is not well recognized. We report 2 cases of primary biliary cirrhosis (PBC) who with time, crossed over to autoimmune hepatitis (AIH). Recognition of such switch over from PBC to AIH is important for appropriate change in management of the patients.

RESUMEN

OBJECTIVES: To analyze association of different HLA genotypes for predisposition to type-I autoimmune hepatitis in Western India. METHODS: This study was undertaken on patients of type-I autoimmune hepatitis (defined by international criteria by IAHG, 1999). HLA genotyping for class I and II was done in 20 patients of autoimmune hepatitis and 100 healthy controls. Statistics were done using Halden's modification of Woolfs formula. RESULT: Significant association of autoimmune hepatitis was found amongst class I antigens--HLA B27 [20 vs. 0 %] & HLA cw4 [40 vs. 15 %] and amongst class II antigens--DRBI*01XX [25 vs. 2%], DRB1*14XX [30 vs. 12%], DRB1*15XX [40 vs. 25%] and DRB1*07XX [20 vs. 9 %] at DRB1 locus. Stronger association was found with HLA B27, cw4 & HLA DRB1 *01XX. CONCLUSION: Our data indicate that predisposition to autoimmune hepatitis is different in Indian patients and not associated with HLA DRB1*03XX or *04XX, as seen in Western world.
