Evaluation of liver and splenic stiffness by acoustic radiation force impulse for assessment of esophageal varices.

BACKGROUND: In routine clinical practice, assessment of portal hypertension (PHT) among patients with liver cirrhosis is done by a upper gastrointestinal endoscopy (UGIE); however, its invasive nature limits its use. Recent advances in ultrasound imaging make it possible to evaluate the tissue stiffness of the liver and spleen reflecting the severity of underlying fibrosis. Liver stiffness and spleen stiffness can be used to predict the presence of esophageal varices/PHT among cirrhotic patients. AIM: To predict the presence or absence of esophageal varices by measuring the stiffness of the liver and spleen by ultrasonography (USG)-based acoustic radiation force impulse (ARFI). METHODS: This cross-sectional study included 90 subjects with liver cirrhosis. Liver and splenic stiffness were measured along with the USG abdomen, UGIE and aspartate aminotransferase to platelet ratio index (APRI). RESULTS: Liver and spleen stiffness were significantly higher in cirrhotic patients compared to chronic hepatitis B. The best cut-off value of liver stiffness (LS) obtained by the receiver operating characteristic (ROC) curve was 2.16 m/s for predicting esophageal varices (AUROC 0.78, p 0.0002). The best cut-off value of splenic stiffness (SS) obtained by the ROC curve was 3.04 m/s for predicting esophageal varices (AUROC 0.698, p 0.0274). When both LS and SS were taken together, the accuracy in predicting esophageal varices increased to 92.22%. An equation to predict "esophageal varices = (0.225 LS + 0.377SS) - 0.555" was derived. CONCLUSION: LS and SS values of ≥ 2.16 m/s and 3.04 m/s, respectively, predict esophageal varices independently; however, combined assessment is better with 92% accuracy.

Clinical and demographic comparison of celiac disease diagnosed during adulthood versus childhood and adolescence: A single-center experience.

Background and Aim: Celiac disease (CeD) is mainly reported from the northern and western parts of India. In central India, it is believed to be a disease of children, with limited data among adults diagnosed for the first time after the age of 18 years. Hence, we aimed to describe CeD's clinical and demographic features among adults and children/adolescents in central India. Methods: This is a retrospective analysis of a prospectively maintained database of all patients diagnosed for CeD from 2010 to 2019. The disease in adults was confirmed when symptoms developed for the first time after 18 years and had positive anti-transglutaminase antibodies with villous atrophy on duodenal biopsy. It was compared with pediatric patients with CeD diagnosed during the same time period. Results: Of the 170 patients diagnosed with CeD, 118 were adults and 52 were children or adolescents. The mean age of presentation of adult CeD was 37.3 ± 11.93 years, while in the pediatric and adolescent group it was 9.19 ± 5.4 years. Classical presentation with chronic, painless, small-bowel-type diarrhea was seen in 44.1% of adults compared to 57.7% in the pediatric age group. Among the adult patients, 55.9% presented with nonclassical symptoms, which included abdominal pain (40.7%) and weight loss (36.4%). The common presenting symptom in children other than diarrhea was weight loss (50%) and abdominal pain (34.6%). Conclusion: CeD is common in central India, with an increasing number of patients being diagnosed for the first time after 18 years of age and presenting more often with nonclassical symptoms.

Abdominal pain caused by lead toxicity due to over the counter herbal medicines: A case series.

In the last three decades, the use of herbal medications has been increasing for the treatment of various chronic disorders. Studies in the past have shown that many of these medicines could contain high levels of heavy metals, including lead. Therefore, we planned this study to evaluate the possibility of lead toxicity as the underlying cause in patients consuming these unnamed herbal medicines among patients presenting with significant abdominal pain. (Unexplained abdominal pain means pain in abdomen in which no etiology could be ascertained after all possible routine and specialized investigations including computerized axial tomography [CT] of the abdomen and upper gastrointestinal [UGI] endoscopy/colonoscopy). This is an observational case series of prospectively maintained data of all patients having unexplained abdominal pain and found to have an elevated blood lead level from 2011 to 2019. Lead toxicity was diagnosed when its blood lead level was >25 µg/dL. Total sixty-six patients with unexplained abdominal pain from 2011 to 2019 were recruited. Out of the sixty-six patients, seventeen had elevated blood lead levels. All seventeen patients had a history of ingestion of herbal medicines for more than 6 months. Among the seventeen patients, eight were taking it for infertility and sexual dysfunction, six for diabetes, two for arthritis and one for hypertension. Basophilic stippling was seen in one patient. Fourteen patients had low hemoglobin with a median value of 9.7 g/dL. Mean serum blood lead level was 87.1 µg/dL. None of them required anti-chelating agent. Lead toxicity owing to herbal medicine is not uncommon cause of unexplained abdominal pain. Most of these patients do not require a chelating agent for treatment. There is a need to bring these herbal medicines under strict regulations for displaying its constituents and their concentrations.

Inflammatory bowel disease in central India: a single centre experience over five years.

In this retrospective study, the records of all patients diagnosed with inflammatory bowel disease between 2005 and 2010 were analysed. Ulcerative colitis is far more common than Crohn's disease in our setting. The incidence is similar in both sexes and the age at diagnosis for both is similar. Limited left-sided ulcerative colitis is more common. Crohn's disease is difficult to diagnose and is commonly treated as tuberculosis in our setting.

Acute febrile illness in cirrhosis - thinking beyond spontaneous bacterial peritonitis!

The aim of this study was to look at the aetiological factors presenting as acute febrile illness in cirrhotic patients. The study group included all cirrhotic patients admitted as inpatients between January and December 2011 with a history of fever of less than seven days duration. Detailed history, clinical examination and investigations, as required, were noted. The data collected were analysed. A total of 42 patients formed the study group. The male-to-female ratio was 9.5:1. The mean age at presentation was 45.09 years (24-77 years). The aetiological factors for fever were: spontaneous bacterial peritonitis (20), lower respiratory tract infection (8), urinary tract infection (6), lower limb cellulitis (4), acute cholecystitis (2) and malaria (2). The mean MELD (model for end-stage liver disease) score at presentation was 20.4. Three patients with spontaneous bacterial peritonitis (SBP) and a mean MELD score of 31 died during the hospital admission. Febrile illness in cirrhosis is attributable to multiple causes. Outcome is dependent on the severity of underlying liver disease.

Role of intravenous naloxone in severe pruritus of acute cholestasis.

Pruritus is a well-known manifestation of various cholestatic disorders. Increased opioidergic tone is one of the mechanisms for this. This prospective, uncontrolled study was done to determine the efficacy of intravenous naloxone in pruritus of acute cholestasis. Twenty-two patients with severe pruritus (based on visual analogue scale [VAS] score of 0-100 and associated symptoms) were treated with intravenous naloxone (0.4 mg every 8 hours) for at least 48 hours. Viral hepatitis E was found to be the most common etiology for cholestatic pruritus (n=12). Eighteen patients (81.8%) patients had significant reduction in VAS after 48 hours of starting naloxone; these patients also showed reduction in alkaline phosphatase and gamma glutamyl transpeptidase. There was no side-effect or 'breakthrough' phenomenon noted in any patient over next 6 weeks. Naloxone is safe and efficacious in symptomatic improvement in cholestatic pruritus.
