Spontaneous dissection of the superior mesenteric artery related to COVID-19.

Background: Spontaneous peripheral dissections are rare, and in a substantial number of cases, the underlying aetiology remains unclear. Patients and methods: We report the case of a 63-year-old male patient with a recent asymptomatic SARS-CoV-2 infection who presented with sudden-onset intermittent abdominal pain. Imaging studies revealed a dissection of the superior mesenteric artery (SMA) and large-vessel vasculitis involving the SMA as well as the carotid, subclavian, axillary and femoropopliteal arteries. In the absence of other predisposing factors, we supposed an association with prior COVID-19 and performed a systematic review of the literature to search for similar cases with arterial dissection related to acute or recent SARS-CoV-2 infection. Results: We identified 25 cases, including ours: 13 males and 12 females, with a median age of 48 years. In 22/25 patients, arterial dissection occurred within 4 weeks after the diagnosis of COVID-19 and involved the cerebral (11/25; 44%), coronary (10/25; 40%), splanchnic (3/25; 12%) and renal (2/25; 8%) arteries. Conclusions: Although initially known for its respiratory manifestations, it has become evident that SARS-CoV-2 not only infects pneumocytes but also enters the vascular endothelium, leading to endothelial dysfunction and hypercoagulability and - as shown in our case - large-vessel vasculitis, which may predispose patients to intramural haemorrhage and arterial dissection.

Excess burden of respiratory and abdominal conditions following COVID-19 infections during the ancestral and Delta variant periods in the United States: An EHR-based cohort study from the RECOVER Program (preprint)

Importance The frequency and characteristics of post-acute sequelae of SARS-CoV-2 infection (PASC) may vary by SARS-CoV-2 variant. Objective To characterize PASC-related conditions among individuals likely infected by the ancestral strain in 2020 and individuals likely infected by the Delta variant in 2021. Design Retrospective cohort study of electronic medical record data for approximately 27 million patients from March 1, 2020-November 30, 2021. Setting Healthcare facilities in New York and Florida. Participants Patients who were at least 20 years old and had diagnosis codes that included at least one SARS-CoV-2 viral test during the study period. Exposure Laboratory-confirmed COVID-19 infection, classified by the most common variant prevalent in those regions at the time. Main Outcome(s) and Measure(s) Relative risk (estimated by adjusted hazard ratio [aHR]) and absolute risk difference (estimated by adjusted excess burden) of new conditions, defined as new documentation of symptoms or diagnoses, in persons between 31-180 days after a positive COVID-19 test compared to persons with only negative tests during the 31-180 days after the last negative test. Results We analyzed data from 560,752 patients. The median age was 57 years; 60.3% were female, 20.0% non-Hispanic Black, and 19.6% Hispanic. During the study period, 57,616 patients had a positive SARS-CoV-2 test; 503,136 did not. For infections during the ancestral strain period, pulmonary fibrosis, edema (excess fluid), and inflammation had the largest aHR, comparing those with a positive test to those with a negative test, (aHR 2.32 [95% CI 2.09 2.57]), and dyspnea (shortness of breath) carried the largest excess burden (47.6 more cases per 1,000 persons). For infections during the Delta period, pulmonary embolism had the largest aHR comparing those with a positive test to a negative test (aHR 2.18 [95% CI 1.57, 3.01]), and abdominal pain carried the largest excess burden (85.3 more cases per 1,000 persons). Conclusions and Relevance We documented a substantial relative risk of pulmonary embolism and large absolute risk difference of abdomen-related symptoms after SARS-CoV-2 infection during the Delta variant period. As new SARS-CoV-2 variants emerge, researchers and clinicians should monitor patients for changing symptoms and conditions that develop after infection.

Double peptic ulcer perforation in a Covid-19 patient, extremely rare entity.

Peptic ulcer perforation is one of the leading causes of acute abdomen, presenting with acute abdominal pain and severe distress for the patient. In one-third of patients, the presentation is less dramatic, resulting in significant delays in diagnosis. Herein, we present a very rarest case operated on for diffuse purulent peritonitis with double perforation of the stomach in a COVID-19-positive patient, which had a depressing outcome.

Diagnostic performance of serum pentraxin-3 in pediatric acute appendicitis: a prospective diagnostic validation study.

INTRODUCTION: Pediatric acute appendicitis (PAA) is a pathology with a high rate of diagnostic error. The search for new diagnostic tools is justified by the high morbidity and healthcare costs associated with diagnostic error. METHODS: We designed a prospective study to validate serum pentraxin-3 (PTX3) as a diagnostic tool in PAA. Participants were divided into three groups: (1) patients with no underlying pathology (2) patients with non-surgical abdominal pain and (3) patients with a confirmed diagnosis of PAA. For further analyses, patients in group 3 were divided into complicated or uncomplicated PAA. Quantitative variables were expressed as medians and interquartile ranges and categorical variables as percentages. Quantitative variables were compared using the Kruskal-Wallis test and the Mann-Whitney U test. Diagnostic performance was evaluated with ROC curves. RESULTS: This study included 215 patients divided into group 1 (n = 63), group 2 (n = 53) and group 3 (n = 99). Median serum PTX3 values were 2.54 (1.70-2.95) ng/mL, 3.29 (2.19-7.64) ng/mL and 8.94 (6.16-14.05) in groups 1, 2 and 3, respectively (p = 0.001). Patients with complicated PAA showed significantly higher values than patients with uncomplicated PAA (p = 0.04). The AUC (group 2 vs. 3) was 0.77 (95% CI 0.69-0.85) and the best cut-off point was at 7.28 ng/mL, with a sensitivity of 61.3% and a specificity of 73.1%. The AUC (complicated vs. uncomplicated PAA) was 0.65 (95% CI 0.54-0.77) and the best cut-off point was 12.33 ng/mL, with a sensitivity of 51.72% and a specificity of 72.73%. CONCLUSIONS: The diagnostic ability of serum PTX3 in PAA is only moderate and therefore it cannot be considered a definitive diagnostic test. The discriminatory ability of PTX3 between complicated and uncomplicated PAA is poor. These findings, which contrast with those reported to date, should be validated with future properly designed prospective studies.

Terminal ileitis and cytotoxic lesion of corpus callosum as the presenting features of Multisystem inflammatory syndrome in children (MIS-C): a case report.

BACKGROUND: Multisystem inflammatory syndrome in children (MIS-C) is a post-viral inflammatory vasculopathy characterized by persistent fever, multiorgan dysfunction, significant laboratory markers of inflammation, lack of an alternative diagnosis, and prior SARS-CoV-2 infection or exposure in children and adolescents. The most common early symptoms include a prolonged fever, as well as dermatologic, mucocutaneous, and gastrointestinal symptoms such abdominal pain, vomiting, and diarrhea. CASE PRESENTATION: We present a pediatric patient with multisystem inflammatory syndrome with the development of abdominal pain and seizure who was found to have a circumferential wall thickening of the terminal ileum and ileocecal junction in abdominal CT scan. The brain MRI of the patient showed cytotoxic lesions of the corpus callosum (CLOCC) which had hypersignal intensity with a few diffusion restrictions in the splenium of the corpus callosum. CONCLUSION: This case is being reported to raise awareness of MIS-C presenting characteristics. Given the rising number of MIS-C patients and a lack of understanding regarding early diagnostic clinical characteristics and therapy, further research into clinical presentations, treatment, and outcomes is urgently needed.

Prevalence and risk factors of anxiety and depression in patients with liver cirrhosis during the COVID-19 pandemic (preprint)

Background Patients with cirrhosis are prone to mental and psychological problems. However, data on mental and psychological problems in patients with cirrhosis during the coronavirus disease 2019 (COVID-19) pandemic are lacking. Therefore, we aimed to investigate the prevalence and risk factors of anxiety and depression in this population.Methods The Patient Health Questionnaire-9 Scale and Generalized Anxiety Disorder 7-item scale were used to collect mental health data in this cross-sectional study. Multivariate logistic regression analysis was performed to evaluate the relevant influencing factors of anxiety and depression.Results The prevalence rates of anxiety and depression in patients with cirrhosis were 21.3% and 29.9%, respectively. Anxiety risk was higher among patients with cirrhosis who had significant abdominal pain and treatment interruption; COVID-19 vaccination was associated with anxiety reduction as a protective factor. Depression risk was higher among patients with cirrhosis for > 10 years, significant abdominal pain within one week, and treatment interruption. Course of cirrhosis of 5–10 years and COVID-19 vaccination were associated with the reduction of depression as protective factors.Conclusion COVID-19 vaccination is a protective factor for both depression and anxiety. Our findings may help healthcare professionals to develop appropriate treatment strategies and timely psychological interventions.

The clinical course and outcomes of SARS-CoV-2 infection in children: A 24-week follow-up study in Sulaimaniyah, Iraq (preprint)

Most children infected with SARS-CoV-2 have asymptomatic or mild disease with a short clinical course and excellent outcome; meanwhile, some children experienced persisting symptoms lasting > 12 weeks from the COVID-19 diagnosis. This study aimed to define the acute clinical course of SARS-CoV-2 infection and outcomes in children after recovery. This prospective cohort study was conducted on 105 children (aged < 16 years) with confirmed COVID-19 infection at Jamal Ahmed Rashid Teaching Hospital, Sulaimaniyah, Iraq, from July to September 2021. The symptomatic and suspicious cases of COVID-19 infection in children were confirmed by real-time reverse transcriptase-polymerase chain reaction (RT-PCR) on nasopharyngeal swabs. About 85.6% of children fully recovered at ≤ 4 weeks from initial COVID-19 diagnosis, 42% were hospitalized, while 15.2% reported long COVID-19 symptoms. The most commonly reported symptoms were fatigue (7.1%), hair fall (4.0%), lack of concentration (3.0%), and abdominal pain (2.0%). Children aged 11–16 years showed a greater risk of long COVID-19 symptoms. We also observed a higher risk of post-COVID-19 symptoms in those who reported ongoing symptoms at 4–6 weeks of follow-up assessment (p = 0.01). Despite mild disease and complete recovery in most children, many suffered from post-COVID symptoms.

Redistribution and activation of CD16brightCD56dim NK cell subset to fight against Omicron subvariant BA.2 after COVID-19 vaccination (preprint)

With the alarming surge in COVID-19 cases globally, vaccination must be prioritised to achieve herd immunity. Immune dysfunction is detected in the majority of patients with COVID-19; however, it remains unclear whether the immune responses elicited by COVID-19 vaccination function against the Omicron subvariant BA.2. Of the 508 Omicron BA.2-infected patients enrolled, 102 were unvaccinated controls and 406 were vaccinated. Despite the presence of clinical symptoms in both groups, vaccination led to a significant decline in nausea or vomiting, abdominal pain, headache, pulmonary infection, overall clinical symptoms, and a moderate rise in body temperature. Omicron BA.2-infected individuals were also characterised by a mild increase in both serum pro- and anti-inflammatory cytokine levels after vaccination. There were no significant differences or trend changes between T and B lymphocyte subsets; however, a significant expansion of NK lymphocytes in COVID-19-vaccinated patients was observed. Moreover, the most effective CD16brightCD56dim subsets of NK cells showed increased functional capacities, as evidenced by a significantly greater IFN-{gamma} secretion and stronger cytotoxic potential in Omicron BA.2-infected patients after vaccination. Collectively, these results suggest that COVID-19 vaccination interventions promote the redistribution and activation of CD16brightCD56dim NK cell subsets against viral infections, and could facilitate the clinical management of Omicron BA.2-infected patients.

Effect of gastrointestinal symptoms and skipping breakfast on anxiety and depression in quarantined Chinese college students during the COVID-19 pandemic: A cross sectional survey (preprint)

Background: Strict quarantine is an effective measure to prevent the spread of the Coronavirus disease (COVID-19) pandemic, but it probably increases the risk of anxiety and depression. We aimed to evaluate the anxiety and depression among quarantined college students at school during the COVID-19 pandemic and investigate whether gastrointestinal discomfort related-factors and skipping breakfast lead to increased risk of anxiety and depression. Methods: 384 quarantined college students in Shanghai China were recruited in this cross-sectional study from April 5th to May 29th, 2022. Generalized Anxiety Disorder (GAD-7) and Patient Health Questionnaire (PHQ-9) were used to assess anxiety and depression, respectively.Results: The prevalence of anxiety and depression were 56.8% and 62.8%, respectively. Longer quarantine duration, higher education level, skipping breakfast, stomachache or abdominal pain, and nausea or dyspepsia were the risk factors for anxiety. Moreover, longer quarantine duration, being woman, skipping breakfast, stomachache or abdominal pain, and nausea or dyspepsia increased the risk of depression. Notably, regularly physical exercising and taking positive attitude towards COVID-19 can reduce the risk of anxiety and depression. Conclusions: More attention should be paid to anxiety and depression of quarantined college students and universities should provide timely psychological monitoring and intervention services to mitigate the impact of negative emotions on students. And effectively relieving gastrointestinal symptoms, insisting on eat breakfast, regularly exercising, and taking a positive attitude towards to COVID-19 might contribute to preventing the anxiety and depression for those college students experiencing a long-term quarantine.

Evaluation of community-based CT abdomen for acute abdominal pain during COVID-19.

AIM: The purpose of this study was to determine the utility of community-based imaging to reduce use of inpatient surgical resources and enforce social distancing at the outset of the COVID-19 pandemic. METHOD: A prospective evaluation of community-based CT for patients presenting to Christchurch general practitioners with acute abdominal pain from April to November 2020. Eligible patients were discussed with the on-call general surgical team, and then referred for CT abdomen rather than hospital assessment. The positivity rate of CT scans, the 30-day all-cause hospital admission rate, and the proportion of patients where community scanning altered management setting and the number of incidental findings, were all assessed. RESULTS: Of 131 included patients, 67 (51%) patients had a positive CT scan. Thirty-nine (30%) patients were admitted to hospital within 30 days, 34 (87%) of whom had a positive CT scan and were admitted under a surgical specialty. Ninety-two (70%) patients did not require hospital admission for their acute abdominal pain, thirty-three (35%) of whom had a positive CT scan. There were three deaths within 30 days of the community CT, and the setting of the community CT did not contribute to the death of any of the cases. Forty patients (30%) had incidental findings on CT, 10 (25%) of which were significant and were referred for further investigation. CONCLUSION: Community based abdominal CT scanning is a feasible option in the management of acute abdominal pain. While trialed in response to the initial nationwide COVID-19 lockdown in New Zealand, there may be utility for acute community-based CT scanning in regular practice.

Abdominal Manifestations of Multisystem Inflammatory Syndrome in Children: A Single-Center Experience.

OBJECTIVES: We reviewed the cases of probable multisystem inflammatory syndrome in children (MIS-C) to identify those cases that mimicked surgical emergencies. METHODS: Records of children managed for MIS-C during a 15-month period between March, 2020 and April, 2021 were retrieved. Data on clinical presentation, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RT-PCR report, SARS-CoV-2 antibody status, blood investigations, radiological investigations and management were collected. RESULTS: A total of 28 out of 83 children with probable MIS-C had acute abdominal symptoms and signs. Fifteen children had mild features like diffuse abdominal pain or non-bilious vomiting, and the remaining 13 (46.2%) had severe abdominal signs or bilious vomiting. Four children worsened with conservative treatment for MIS-C and were detected with perforated appendicitis. Two more children developed recurrent appendicitis on follow up. One child with appendicitis who underwent laparoscopic appendectomy, later manifested with MIS-C. CONCLUSION: Surgical abdominal emergencies may be confused with or occur concurrently in children with MIS-C that should be identified with a high index of suspicion.

Utility of monocyte distribution width for diagnosing colonic diverticulitis in the emergency department: a retrospective cohort study (preprint)

Background Colonic diverticulitis is a leading cause of abdominal pain. The monocyte distribution width (MDW) is a novel inflammatory biomarker with prognostic significance for coronavirus disease and pancreatitis; however, no study has assessed its correlation with the severity of colonic diverticulitis. Methods This single-center retrospective cohort study included patients older than 18 years who presented to the emergency department between November 1, 2020, and May 31, 2021, and received a diagnosis of acute colonic diverticulitis after abdominal computed tomography. The characteristics and laboratory parameters of patients with simple versus complicated diverticulitis were compared. The significance of categorical data was assessed using the chi-square or Fisher’s exact test. The Mann–Whitney U test was used for continuous variables. Multivariate regression analysis was performed to identify predictors of complicated colonic diverticulitis. Receiver operator characteristic (ROC) curves were used to test the efficacy of inflammatory biomarkers in distinguishing simple from complicated cases. Results Of the 160 patients enrolled, 21 (13.125%) had complicated diverticulitis. Although right-sided was more prevalent than left-sided colonic diverticulitis (70% versus 30%), complicated diverticulitis was more common in those with left-sided colonic diverticulitis (61.905%, p = 0.001). Age, white blood cell (WBC) count, neutrophil count, C-reactive protein (CRP) level, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and MDW were significantly higher in the complicated diverticulitis group (p < 0.05). Logistic regression analysis indicated that the left-sided location and the MDW were significant and independent predictors of complicated diverticulitis. The area under the ROC curve (AUC) was as follows: MDW, 0.870 (95% confidence interval [CI], 0.784–0.956); CRP, 0.800 (95% CI, 0.707–0.892); NLR, 0.724 (95% CI, 0.616–0.832); PLR, 0.662 (95% CI, 0.525–0.798); and WBC, 0.679 (95% CI, 0.563–0.795). The MDW had the largest AUC for diagnosing complicated diverticulitis; when the MDW cutoff was 20.38, the sensitivity and specificity were maximized to 90.5% and 80.6%, respectively. Conclusions Patients with complicated diverticulitis were significantly older and predominantly had left-sided colonic diverticulitis. A large MDW was a significant and independent predictor of complicated diverticulitis. The MDW may aid in planning antibiotic therapy for patients with colonic diverticulitis in the emergency department.

Patient satisfaction after remotely delivered gut-directed hypnotherapy for irritable bowel syndrome during the COVID-19 era: implications for future practice.

OBJECTIVE: Gut-directed hypnotherapy (GDH) is an evidence-based treatment for irritable bowel syndrome (IBS). Adoption of remote GDH has been accelerated by the COVID-19 pandemic. We aimed to evaluate patient experience and satisfaction following remote GDH. DESIGN: On completing 12 sessions of remote GDH via Skype using the Manchester protocol, patients with refractory IBS completed a feedback form on their experience. The proportion reporting positive outcomes (≥30% improvement in global IBS symptoms or abdominal pain, satisfaction, recommendation to family/friends) were compared by patient factors (age, gender, proximity, preferences). RESULTS: Of 52 patients completing the feedback form, 27 (52%) indicated that they would have opted for remote over face-to-face GDH, regardless of the pandemic situation. On a five-point scale (5=easy), patients rated the platform easy-to-use (mean 4.5±0.8) without impairment of communication (mean rating 4.6±0.8). Following remote GDH, 30/52 (58%) reported ≥30% global IBS symptom improvement, and 24/52 (46%) reported ≥30% pain reduction. 90% would recommend remote GDH to others. Only 39% felt they would have benefitted more from face to face. Those who would have chosen remote GDH regardless of the pandemic were more likely to be satisfied (p=0.01). Age, gender and proximity did not influence outcomes, satisfaction and likelihood of recommending remote GDH to others. Difficulties during remote sessions were infrequent in both those that were satisfied, and those that would have preferred face to face. CONCLUSION: These data support the need to continue developing remote GDH in the post-COVID era but suggest that there is still a role for face-to-face GDH, with patient choice being an important factor.

Coronavirus disease 2019-related Kawasaki syndrome: a case report.

BACKGROUND: Coronavirus disease 2019 has changed the pattern of some diseases in the world, especially in pediatrics. Despite data suggesting that the pediatric population is less affected by coronavirus disease-19 infection, new concerns have been raised owing to reported cases with hyperinflammatory conditions such as Kawasaki disease. CASE PRESENTATION: We report herein the case of a pediatric patient diagnosed and treated for classic Kawasaki disease in the setting of confirmed coronavirus disease 2019 infection. She was an 8-year-old, previously healthy, and fully immunized Iranian girl who initially presented to the pediatric emergency department with 5 days of intermittent fever, followed by abdominal pain, nausea, and vomiting. She was admitted for fever and abdominal pain to the surgery service of Akbar Hospital with suspected appendicitis. CONCLUSIONS: This case report may serve as a useful reference to other clinicians caring for pediatric patients affected by coronavirus disease 2019 infection. Standard therapeutic interventions for Kawasaki disease must be performed to prevent critical coronary aneurysm-related complications in the coronavirus disease 2019 era.

Acute pancreatitis masquerading as mesentric growth in COVID-19 patient: A case report.

COVID-19 is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It commonly affects the respiratory system, producing pneumonia-like symptoms. Among extrapulmonary manifestations, involvement of the gastrointestinal tract is common with symptoms of nausea, vomiting, diarrhea, and abdominal pain. Coronavirus acts by targeting the ACE-2 receptors in the alveoli of the lungs, but because these receptors are also present in other organs, such as the pancreas, it can affect the pancreas as well, thus causing acute pancreatitis. We here discuss a case of a 72-year-old hypertensive male with COVID-19 who presented with atypical presentation of acute abdominal pain and a few episodes of vomiting. Laboratory investigations were inconclusive. Imaging findings were suggestive of small bowel obstruction and perforation; thus, an exploratory laparotomy was done in which a mesenteric growth was found, reported as acute pancreatitis on histopathology. Therefore, attention should be paid to the pancreatic involvement and atypical presentations in COVID-19 patients.

Telemedicine and intraductal papillary mucinous neoplasms: Analysis of a new follow-up strategy during COVID-19 outbreak.

BACKGROUND: The Coronavirus pandemic outbreak in 2019 and the saturation of healthcare system led to an increased use of digital tools for surveillance. In this study we described our experience using telemedicine to follow-up on patients with intraductal papillary mucinous neoplasms during the COVID-19 era and analyze those factors associated to patients' satisfaction. METHODS: This 1-year retrospective observational study enrolled patients with intraductal papillary mucinous neoplasms followed-up by telemedicine during COVID-19 outbreak. Patients with high-risk features needing on-site physical examination or declining remote follow-up were excluded. A 13-question survey was conducted; demographic, geographic, and employment information was collected. Univariate and multivariate analyses were performed to evaluate those factors associated to patients' satisfaction. RESULTS: Out of 287, a total of 177 patients with intraductal papillary mucinous neoplasms were included: the mean age was 69 (44-87) years and the male/female ratio was 0.78. A total of 80 (45.2%) patients had previously experienced abdominal pain. Most patients (85.3%) were satisfied with telemedicine: at univariate analysis, age ≥70 years (P = .007), retirement (P = .001), and absence of previous abdominal pain (P = .05) were significantly associated with patient satisfaction. At multivariate analysis, the absence of previous abdominal pain was the only factor independently associated with patient satisfaction (odds ratio 5.964, 95% confidence interval 2.21-16.11, P < .001). CONCLUSION: Telemedicine allows a new follow-up strategy that can be used in selected patients with intraductal papillary mucinous neoplasms. The absence of previous abdominal pain is associated with patient satisfaction during follow-up. Further studies are needed to evaluate safety of remote follow-up in patients with intraductal papillary mucinous neoplasms.

Abdominal pain in children with COVID-19.

OBJECTIVE: To analyze clinical features, diagnosis and treatment of pediatric patients referred to our pediatric surgery center with abdominal pain as a main manifestation of COVID-19. MATERIAL AND METHODS: We retrospectively reviewed 56 patients with abdominal pain associated with SARS-CoV-2 infection at the Basrah Children Specialty Hospital between June 2020 and December 2021. We collected data including demographic data, symptoms, imaging data, laboratory findings, treatments, and clinical outcomes. RESULTS: Fifty-six patients (48 male and 8 female) with a median age of 9 years were analyzed. All patients had abdominal pain. Fifty-two patients complained of vomiting, 48 patients with fever, 36 patients with cough, and 20 patients with shortness of breath. Twenty patients were diagnosed with acute appendicitis, two of them had appendicular abscess. Mesenteric lymphadenitis was found in 12 patients, obstructed inguinal hernia in 4 patients, and epididymo-orchitis in two patients. Ten patients required surgical intervention. CONCLUSION: COVID-19 should be suspected in any child presenting with acute abdominal pain. In the era of COVID-19, all cases of abdominal pain in children including those with acute appendicitis are better to be treated conservatively.

Acute pancreatitis in pregnancy following COVID-19 vaccine: a case report.

BACKGROUND: Since the approval of the Pfizer-BioNTech (BNT162b2) mRNA vaccine for COVID-19 infection, a few adverse effects have been reported. Acute pancreatitis has been reported in a few patients. However, there is currently no research showing a direct relationship between the vaccine and acute pancreatitis. Here, we report a case of acute pancreatitis following Pfizer vaccination in a young healthy pregnant woman without any known risk factors. To our knowledge, this is the first case report of possible vaccine-induced pancreatitis in a pregnant woman. CASE PRESENTATION: The patient, a 24-year-old South-Asian female, at 31 weeks of gestation, presented with severe epigastric pain radiating to the back and worsening on lying supine, associated with nausea and vomiting. She was diagnosed with acute pancreatitis with a serum lipase level of 4376 U/L and an ultrasound showing features of pancreatitis. The patient received her first dose of the Pfizer vaccine 1 week prior to these symptoms. Detailed evaluation did not show any etiological cause of pancreatitis. The patient had a spontaneous vaginal delivery and the baby was shifted to the neonatal intensive care unit in a stable condition. A computed tomography scan postpartum (day 2) demonstrated acute interstitial edematous pancreatitis. The patient was managed conservatively in the intensive care unit and discharged home in a stable condition. CONCLUSION: This report highlights the importance of a detailed history and evaluation, and the close monitoring of any patient presenting with abdominal pain after vaccination. Acute pancreatitis can be fatal if not picked up early.
