Atypical Presentation of Adult-Onset Still's Disease.

Adult-onset Still's disease (AOSD) is a rare rheumatic disorder with various presentations. It is diagnosed based on the Yamaguchi criteria, besides the exclusion of infectious diseases and other rheumatic disorders and malignancies. Here, we describe a case of a young man, presenting with remittent fever, abdominal pain, and persistent nausea. Further evaluations showed elevated acute phase reactants, abnormal levels of liver transaminase, multiple lymphadenopathies, and pleural effusion. He was finally diagnosed with AOSD and responded well to corticosteroids and methotrexate. We describe the present case to alert gastroenterologists to AOSD as a rare differential diagnosis in patients with persistent gastrointestinal symptoms.

Post-COVID-19 syndrome mimicking cholangiocarcinoma: A case report.

Key Clinical Message: The differential diagnosis of post-COVID-19 syndrome is important in patients with symptoms of biliary obstruction. This patient had severe COVID-19 who underwent ERCP and mimicked cholangiocarcinoma. Abstract: Patients with severe coronavirus disease 2019 (COVID-19) manifest liver injuries with pathological changes because of lowered blood oxygen saturation, cardiac malfunction, hepatotoxic drugs during treatment, and cellular injury. This paper reports a patient with a history of severe COVID-19 who mimics cholangiocarcinoma after undergoing endoscopic retrograde cholangiopancreatography (ERCP). It was shown that differential diagnosis of post-COVID-19 syndrome is greatly important mostly in patients with symptoms of biliary obstruction.

Association between Pattern of Gastritis and Gastroesophageal Reflux Disease in Patients with Helicobacter Pylori Infection.

BACKGROUND Reflux disease is a common gastrointestinal problem. The association between reflux disease and gastritis pattern is controversial. AIM: To determine the association between reflux disease and gastritis pattern in patients with Helicobacter pylori (H. pylori) infection. METHODS 470 patients with dyspepsia and reflux disease were enrolled in this study. The inclusion criteria were willing to participate in the study, age over 40 years, and having the criteria of ROME III for at least 3 months. Patients with history of H. pylori eradication therapy during the 3 months before the study, a history of gastric surgery, and gastric cancer were excluded. All of the participants underwent upper endoscopy and two biopsy samples were taken from antrum, body, and fundal areas. RESULTS H. pylori infection rate was 367 (78.1%) with mean age of 59.8 ± 11.4 years. Of them 131 patients (35.7%) were male. Reflux disease was detected in 273 (74.4%) patients. 216 (58.9%) and 102 (27.8%) patients had non-erosive reflux disease (NERD) and gastroesophageal reflux disease (GERD), respectively. Corpus predominant and antral predominant gastritis were seen in 72 (19.6%) and 129 (35.2%) patients, respectively. Antral gastritis was significantly associated with GERD (p<0.01). In regression analysis, antral predominant gastritis had a significant association with GERD (OR=1.92; 95%CI: 1.22- 3.12). The same result was observed in mild to moderate antral and greater curvature gastritis (OR= 1.26; 95%CI: 0.25-6.40 and OR= 3.0; 95%CI: 0.63-14.17, respectively). CONCLUSION According to these finding ,we could suggest that the pattern of gastritis could be associated with reflux disease and GERD.

A population based study on hepatitis B virus in northern iran, amol.

BACKGROUND: Viral hepatitis is a major health problem worldwide. Change in transmission patterns of hepatitis B makes it necessary to re-evaluate its prevalence and risk factors. OBJECTIVES: We aimed to determine the prevalence of HBV infection and its related risk factors in Amol city, Northern Iran. PATIENTS AND METHODS: As a population based study, a cluster sampling approach was used and 6146 individuals from the general population of urban and rural areas of Amol, Iran, from both genders and different ages were enrolled. Inclusion criteria were willingness to participate in the study, being a lifelong resident in Amol city or its surrounding areas with Iranian nationality. Ten milliliters (10 mL) of blood was taken from each study subject and checked regarding hepatitis B markers including HbsAg, HBsAb and HBcAb using a third generation ELISA. The prevalence of HBV infections and its potential risk factors were recorded. RESULTS: The prevalence of HBsAg, HBsAb and HBcAb were estimated as 0.9%, 30.7% and 10.5%, respectively. The mean age of all participants was 43.9 (95% CI: 43.4, 44.3) in females and 55.6 in (n = 3472) males. In our study, there was a significant association between family history of hepatitis, rural residency and presence of HBsAg. There was also a positive correlation between HBcAb and family history of hepatitis, history of other types of hepatic diseases, history of tattooing, traditional phlebotomy, male gender and age. In backward logistic regression, a significant association was found between history of hepatitis in first-degree family members (OR = 13.35; 95% CI: 6.26, 28.47) and place of residence (OR = 2.32; 95% CI: 1.27, 4.22) with presence of HBsAg. There was also a positive correlation between history of hepatitis among first-degree family members (OR = 2.49; 95% CI: 1.52, 4.08), history of tattooing (OR = 2.13; 95% CI: 1.33, 3.42), history of previous hepatitis (OR = 1.87; 95% CI: 1.06, 3.28), male sex (OR = 1.36; 95% CI: 1.12, 1.66) and age (OR = 1.03; 95% CI: 1.03, 1.04) with presence of HBcAb. CONCLUSIONS: The prevalence of hepatitis B in Amol City and its surrounding areas was about one percent, a lower rate than other reports from Iran.

Association between Helicobacter pylori and Serum Leptin in Iranian Dyspeptic Patients.

BACKGROUND: To investigate any possible relationship between serum leptin level and H.pylori infection in dyspeptic Iranian adults. METHODS: A total of 153 dyspeptic patients referring to Firoozgar hospital for esophagogastroduodenoscopywere enrolled in the study. Serum leptin level was measuredbefore endoscopy, after overnight fasting. Two biopsy specimens weretaken from antrum for each patient during endoscopy: one to detect H. pyloriinfection by Rapid Urease Test (RUT) and the other evaluated by an expertpathologist, blind to the RUT results and patients. Serum leptin level was comparedbetween H.pylori-positive negative groups. RESULTS: A total of 153 dyspeptic patients with the mean age of 43.2±14.3 years wereevaluated. The overall prevalence of H.pylori infection was 49.6%. H.pyloriinfection was significantly associated with serum leptin level (p<0.001). In addition,we found a significant relationship between serum leptin level and gender(p<0.02). Furthermore, serum leptin level was correlated with age (r=0.17,p=0.0031). However, the H.pylori-positive group was older in comparison tothe H.pylori negative group (45.65±13.9 vs. 40.7±14.13, p=0.035). The twogroups were not significantly different in terms of gender, height, weight orBMI. CONCLUSION: H.pylori infection may influence leptin production. Advanced age might exposethe individual to H.pylori infection and consequently influence the leptinlevel.

Persistent alanine aminotransferase elevation among the general Iranian population: prevalence and causes.

AIM: To determine the prevalence and causes of persistently elevated alanine aminotransferase (ALT) levels among the general population in northern Iran. METHODS: A total of 2292 (1376 female, aged 18-75 year), were selected by systematic clustered random sampling from the cities and villages of Gonbad and Kalaleh in Golestan Province and invited to participate in the study. A comprehensive history regarding alcohol drinking and medication was taken. Body mass index (BMI), viral markers and ALT levels were measured. If ALT level was > or = 40 U/L, it was rechecked twice within 6 mo. Those with > or = 2 times elevation of ALT were considered as having persistently elevated ALT level. Non-alcoholic fatty liver disease (NAFLD) was diagnosed based on evidence of fatty liver upon sonography and excluding other etiology. RESULTS: A total of 2049 (1351 female) patients participated in the study, 162 (7.9%) had elevated ALT level at the first measurement. Persistently elevated ALT level was detected in 64 (3.1%) participants, with 51 (79.6%) with no obvious etiology, six (9.3%) with Hepatitis B, four (6.2%) with Hepatitis C virus (HCV) infection and three (4.6%) with alcoholic hepatitis. The prevalence of NAFLD and alcoholic hepatitis was 2.04% (42 patients) and 0.1% (three), respectively. There was correlation between NAFLD and male gender, overweight, diabetes and living in an urban area [odds ratio = 3.03 (95% CI: 1.6-5.72), 4.21 (95% CI: 1.83-9.68), 2.86 (95% CI: 1.05-7.79) and 2.04 (95% CI: 1.00-4.16) respectively]. CONCLUSION: NAFLD is the most common cause of persistently elevated serum ALT level among the general population of Iran.
