Immune monitoring of a child with autoimmune hepatitis and type 1 diabetes during COVID-19 infection
We present the unique opportunity we had to monitor the liver, IL-6 and immune cell course before, during and after COVID-19 in a boy with autoimmune hepatitis (AIH) and type 1 diabetes (T1D). CD4+ and CD8+ T cells frequencies decreased because of prednisolone, followed by a plateauing increase whereas CD19+CD20+ B cell increased strongly and was unaffected by COVID-19 infection. Moreover, the percentage of activated CD8+ T cells expressing HLA-DR (CD8+HLA-DR+) increased during COVID-19 and subsided after its clearance. Total regulatory T cells (Tregs: CD4+CD25+CD127lowFOXP3+) remained stable. Although activated Tregs (CD4+CD45RA-FOXP3high) strongly increased upon prednisolone, it decreased afterwards. Furthermore, regulatory B cells (Bregs: CD19+CD20+CD24highCD38high) declined sharply owing to prednisolone. Serum IL-6 remained undetectable at all times. We demonstrated for the first time immune monitoring in a child with AIH and T1D before, during and after COVID-19. We hypothesize that continuing with low level of prednisolone without azathioprine may have abrogated activated Tregs, Bregs and IL-6 production and therefore permitting the activation of CD8+ T cells, clearing the virus.

In this report, we describe the case of a SARS-CoV-2 infection (COVID-19) in an infant with mild fever and diarrhea in the absence of respiratory distress. A 45-day-old male infant with COVID-19 was transferred to our pediatric department. He had mild fever and diarrhea at admission. Positive-to-negative nasal swab conversion occurred on the 21st day from the onset of symptoms. However, stool swab positivity persisted during the 6-week admission period and for 7 weeks during follow-up at an outpatient clinic after discharge. Negative conversion in a stool specimen occurred on the 142nd day from the onset of symptoms. This ...
In conclusion, gut inflammation associated with chronic colitis does not mediate a further increase in the cellular entry of SARS-CoV-2. PMID: 32975064 [PubMed - in process]

Conclusions: "Home staying syndrome" is an undefined syndrome of unusual symptoms of abnormal sleep (altering sleep time and duration) and frequent urination> 3 times/hour. This syndrome is associated with staying at home for a long period of time and is easily resolved by doing any activity such as sports or visiting friends. While this syndrome is rare, it may be more prevalent now due to the COVID-19 pandemic, which forces people to stay home for infection prevention. PMID: 32975916 [PubMed - as supplied by publisher]
