Objective: Cytomegalovirus (CMV) infection may rarely lead to protein-losing gastropathy that presents with nausea, vomiting, abdominal pain, and edema in immunocompetent children, but extremely rarely with only generalized edema. Clinical Presentation and Intervention: A previously healthy 5-year-old boy presented with generalized edema without any other symptoms. He had hypoalbuminemia but no proteinuria. He was evaluated for gastrointestinal protein loss, and hypertrophic gastropathy was revealed on esophagogastroduodenoscopy. Meanwhile, CMV infection was detected by serologic tests and polymerase chain reaction in the blood. He recovered spontaneously within a week. Conclusion: CMV-related protein-losing gastropathy may present with generalized edema without any gastrointestinal symptoms.

Acute Cytomegalovirus

The results of a laboratory examination of 520 children aged 1—3 years are presented. The examination was conducted to determine the DNA of cytomegalovirus in children with acute cytomegalovirus infection in various biological media by polymerase chain reaction. The differences in the virus shedding  into the blood, saliva, and urine are established: the median of the viral load for saliva is 4.9 lg copies of DNA/ml, the blood 3.4 lg copies of DNA/ml, urine — 3.85 lg copies of DNA/ml. The cut of extreme values of the viral load are determined with the help of mathematical modeling which determine the clinical probability of developing acute CMV infection which allows for more accurate and timely assignment of etiotropic therapy.

Fecal-orally transmitted cyclosporiasis is frequent in remote resource-limited settings in Central and South America with poor hygiene conditions. In this study, we aimed at assessing seasonal effects on the epidemiology of colonization or infection with C. cayetanensis in Colombian indigenous people living under very restricted conditions. In the rainy season between July and November and in the dry season between January and April, stool samples from indigenous people with and without gastrointestinal symptoms were collected and screened for C. cayetanensis applying in-house real-time polymerase chain reaction (PCR). In the rainy season and in the dry season, positive PCR results were observed for 11.8% (16/136) and 5.1% (15/292), respectively, with cycle threshold (Ct) values of 30.6 (±3.4) and 34.4 (±1.6), respectively. Despite higher parasite loads in the rainy season, fewer individuals (2/16, 12.5%) reported gastrointestinal symptoms compared to the dry season (6/15, 40%). In conclusion, considerable prevalence of C. cayetanensis in Colombian indigenous people persists in the dry season. Low proportions of gastrointestinal symptoms along with higher parasite loads make colonization likely rather than infection.

BACKGROUND: Human cytomegalovirus is an important cause of morbidity and mortality in immunocompromised patients. Qualitative polymerase chain reaction (PCR) has proven to be a sensitive and effective technique in defining active cytomegalovirus infection, in addition to having low cost and being a useful test for situations in which there is no need for quantification. Real-time PCR has the advantage of quantification; however, the high cost of this methodology makes it impractical for routine use.OBJECTIVE: To apply a nested PCR assay to serum (sPCR) and to evaluate its efficiency to diagnose active cytomegalovirus infection compared with PCR of peripheral blood leukocytes (L-PCR).METHODS: Samples of 37 patients were prospectively evaluated. An internal control was created and applied to sPCR to exclude false-negative results.RESULTS: In total, 21 patients (57%) developed active cytomegalovirus infection. After analyzing the two methods for the diagnosis of active infection, higher sensitivity and negative predictive value of the L-PCR versus sPCR (100% versus 62%), and higher specificity and positive predictive value of sPCR versus L-PCR (81% versus 50% and 72%, respectively) were observed. Discordant results were observed in 11 patients who were L-PCR-positive but sPCR-negative for active cytomegalovirus infection, five of whom developed clinical symptoms of cytomegalovirus. Clinical symptoms were observed in 14 patients, 12 of whom were diagnosed with active infection by nested L-PCR (P=0.007) and seven by nested sPCR (P=0.02). Higher specificity and a positive predictive value for sPCR were observed.CONCLUSION: Nested L-PCR and sPCR were considered to be complementary methods for the diagnosis and management of symptomatic cytomegalovirus infection.

Abstract Efforts to recognize SARS–CoV-2 infection have focused on respiratory symptoms such as cough and shortness of breath. Although it is also well known that SARS–CoV-2 infection can cause gastrointestinal symptoms such as abdominal pain, nausea, vomiting and diarrhoea, there are emerging reports of SARS–CoV-2 infection causing surgical pathology. We present the first case report of SARS–CoV-2 infection directly causing acute appendicitis, first suspected due to highly atypical histological features and later confirmed as polymerase chain reaction positive appendicular tissue sample.
