Autoimmune encephalitis (AE) is the result of an autoimmune process that occurs as a rapidly advancing encephalopathy. Autoimmune encephalitis was commonly linked to herpes simplex virus 1 (HSV-1) as the most frequently identified virus. The main areas affected by this invasion are the temporal lobe, frontal lobe, and limbic system. Limbic encephalitis is a highly uncommon occurrence involving anti-alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) encephalitis and anti-IgLON family member 5 (IgLON5) disease, both belonging to the rare category. As far as we know, this is the first report showing that a patient diagnosed with AMPAR encephalitis overlapped with anti-IgLON5 disease post herpes simplex virus encephalitis (HSE), which helps to broaden the range of this uncommon autoimmune disease. We recommend autoantibody testing in all patients with HSE, particularly those involving neurological relapses or progression.

Herpes simplex virus type I (HSV-1) infection is associated with lung injury; however, no specific treatment is currently available. In this study, we found a significant negative correlation between FcRn levels and the severity of HSV-1-induced lung injury. HSV-1 infection increases the methylation of the FcRn promoter, which suppresses FcRn expression by upregulating DNMT3b expression.

Liver transplantation (LT) is a cost-effective therapy for advanced liver disease. Although LT significantly improves long-term survival, it requires strict control of immunosuppressants and their potential complications. Several available immunosuppressive drugs include glucocorticoids, calcineurin inhibitors, mycophenolate, mTOR inhibitors, and anti-CD25 antibodies.

We present a case report of a 72-year-old female with a history of stage III rectal adenocarcinoma undergoing chemotherapy who developed neutropenic sepsis and acute respiratory failure. The patient was admitted to the intensive care unit (ICU) due to worsening respiratory status and was subsequently diagnosed with disseminated herpes simplex virus (HSV) infection including acute respiratory distress syndrome (ARDS). This case highlights the challenges in diagnosing and managing HSV infection in critically ill patients and emphasizes the importance of early recognition and appropriate treatment in improving patient outcomes.

After surgery involving cranial nerves and more generally the central nervous system, nonbacterial meningitis should raise suspicion of herpes simplex virus type 1 reactivation. No time should be wasted in diagnosis and treatment; therefore, a polymerase chain reaction testing on cerebrospinal fluid should be systematic in this situation, without neglecting to consider other differential diagnoses.
