Abstract
Helicobacter pylori is one of the most common bacteria affecting human societies worldwide, and is mainly associated with gastrointestinal complications due to different virulence factors. This study aimed to investigate some virulence genes of H. pylori in gastric biopsies of patients with gastritis in Sari city, North of Iran. Informed consent forms were obtained from the studied patients, and those who needed endoscopy were included in the study. To evaluate the prevalence of cagA, iceA1, iceA2, vacA, dupA, and oipA genes, gastric biopsies with positive or negative rapid urease test were collected from 50 patients (25 in each group) with gastro-duodenal diseases. The bacterial DNAs were extracted by a specific kit, and the presence of the genes was analyzed by PCR using specific primers. Eighteen (72%) biopsies from 25 H. pylori-positive samples were cagA-positive, while 17 (68%) biopsies contained the vacA gene, and 11 (44%) samples had both vacA and cagA genes. However, 16 (64%), 12 (48%), 13 (52%), and 14 (56%) biopsies contained dupA, iceA1, iceA2, and oipA genes, respectively. Due to the significant role of the studied virulence factors in the pathogenicity of H. pylori, the high prevalence of these factors in biopsies of patients with gastritis is a concern needing to the management in this region.

Abstract
Vanishing bile duct syndrome (VBDS) has been postulated that may be related to Hodgkin's lymphoma (HL). In the present study, we present a 75-year-old male patient with HL who received chemotherapy but has not received any radiotherapy. The patient's condition worsened in further days, and he died with the diagnosis of cirrhosis and hepatic failure.

Abstract
BACKGROUND Predictive and prognostic biomarkers to guide 2019 novel coronavirus disease (COVID-19) are critically evolving. Dysregulated immune responses are the pivotal cause of severity mainly mediated by neutrophil activation. Thus, we evaluated the association of calprotectin, neutrophil secretory protein, and other mediators of inflammation with the severity and outcomes of COVID-19. METHODS This two-center prospective study focused on PCR-proven COVID-19 patients (n = 76) with different clinical presentations and SARS-CoV-2 negative control subjects (n = 24). Serum calprotectin (SC) was compared with IL-6 and other laboratory parameters. RESULTS Median levels of SC were significantly higher in COVID-19 patients in comparison to the control group (3760 vs. 2100 ng/ml, p < 0.0001). Elevated SC was significantly respective of disease severity (3760 ng/ml in mild up to 5700 ng/ml in severe cases, p < 0.0001). Moreover, the significant positive and negative correlations of SC with disease severity and oxygenation status indicated disease progression and respiratory worsening, respectively. It was found that SC was high in severe patients during hospitalization and significantly declined to normal after recovery. The logistic analysis identified the independent predictive power of SC for respiratory status or clinical severity. Indeed, SC behaved as a better discriminator for both outcomes, as it exhibited the largest area under the curve (receiver operating curve analysis), with the highest specificity and sensitivity when the predictive value of inflammatory biomarkers was compared. CONCLUSION Calprotectin can be used as a reliable prognostic tool to predict the poor clinical outcomes of COVID-19 patients.

Abstract
BACKGROUND Botulinum toxin (BT) injection reduces lower esophageal sphincter pressure and alleviates symptoms in idiopathic achalasia (IA). Ethanolamine oleate (EO) has also been introduced for the treatment of IA. We compared the long-term efficacy of BT and EO injections in the treatment of IA. METHODS A total of 189 IA patients were evaluated prospectively, of whom 21 were unwilling to undergo or were poor candidates for pneumatic balloon dilation and Heller myotomy and were enrolled in the study. Eleven patients were treated by BT, and 10 by EO injections. Patients were followed up by achalasia symptom score (ASS), timed barium esophagogram (TBE), and high-resolution manometry at baseline and post-treatment. A good initial response was defined as a decrease in ASS to 4 or less, and a reduction in barium column height and volume in TBE by >50%. RESULTS All 10 EO group patients and 10 of 11 BT group patients showed a good initial response. Four EO group relapsers and 6 BT group relapsers were managed effectively by re-injections. Mean duration of follow up was 27.38 months. On completion of the study, a sustained good response was seen in 9 and 6 patients in EO and BT groups, respectively (P=0.149). CONCLUSION This study revealed that BT and EO have comparable efficacy in the treatment of IA. However, the cost of EO is about 2 times lower than BT.
