RESUMO
Introduction: Acute pancreatitis (AP) is a serious inflammatory condition of the pancreas. Hypertriglyceridemia (HTG) is considered an uncommon cause of AP. The current study aims to present a unique case of recurrent seasonal severe HTG-induced AP (HTG-AP); treated with insulin and heparin. Case report: A 36-year-old male presented with recurrent attacks of severe upper abdominal pain that was radiating to the back and associated with repeated vomiting. The condition has being occurring every autumn-winter for the last three years. He had thalassemia minor and had a history of HTG-AP. His TG levels were relatively normal from February to August; however, from September to February, his TG levels highly elevated which has resulted in HTG-AP every year for the past three years. The condition was confirmed via a contrast-enhanced computerized tomography scan of the abdomen. To prevent the next HTG-AP, his TG level was monitored monthly. When TG levels spiked again, the patient was put on an insulin infusion with heparin, glucose, and potassium to rapidly reduce TG level. After two days, serum TG was dramatically reduced (<500 mg/dL). Discussion: Despite multiple theories being proposed, the pathogenesis of HTG-AP is yet to be understood. Usually, HTG-AP is a single episodic, and recurrent HTG-AP is considered uncommon finding. Previous reports are contradictory regarding TG level and seasonal variation. There is currently no standard management approach to treat HTG-AP cases. Conclusion: HTG-AP rarely reoccurs on an annual basis, and seasonal variation seems to play a major role in its onset. The condition can be managed with insulin, heparin, and glucose infusions.
RESUMO
INTRODUCTION: A small portion of Corona Virus disease-2019 (COVID-19) cases associated with co-infections, however occasionally they turn out to be false positive due to possible cross-reactivities. The current report aims to present a rare case of false-positive human immunodeficiency virus (HIV) in a COVID-19 patient. CASE REPORT: A 32-year-old female complaining from thyroid problems referred for thyroid operation. She had mild symptoms of COVID-19. Her preoperative laboratory findings were normal, except for HIV screening test which was repetitively positive. RNA PCR was performed to confirm the diagnosis of HIV, it revealed a negative result. The patient underwent thyroidectomy as planned and was given the required supportive treatment to recover from COVID-19. Two-month follow up revealed that she was negative for COVID-19 on PCR testing, and HIV immunoassay test was no longer positive. DISCUSSION: Due to structural similarities between the spike protein chains of SARS-CoV-2 and some other viruses such as dengue, Zika, and other closely related coronaviruses (SARS-CoV, MERS-CoV), the protein can potentially interfere with the immunoassay tests. Although HIV immunoassay tests have high sensitivity and specificity, false-positive results have been reported, such as in the case of Epstein Barr virus, Influenza vaccination, and the Australian COVID-19 vaccination. CONCLUSION: Similarity between HIV and SARS-CoV-2 spike proteins can lead to antibody cross-reactivities, yielding false-positive results on immunoassay screening tests.
