Immune checkpoint blockade (ICB) therapy has revolutionized the treatment of lung squamous cell carcinoma (LUSC). However, a significant proportion of patients with high tumour PD-L1 expression remain resistant to immune checkpoint inhibitors.

Noma is a rare disease that occurs mainly in malnourished patients in developing countries. Noma starts as facial swelling and gingival necrosis that eventually necrotizes underlying tissues including the jaw bone, leaving severe disfigurement. It is reported extremely rarely in patients with severe immunosuppression or blood dyscrasia.

Cytomegalovirus establishes life-long latency after primary infection in childhood. Cytomegalovirus reactivation has been well reported in immune-compromised patients; however, in the last few years it has been observed that cytomegalovirus reactivation also occurs in critically ill patients without exogenous immunosuppression, which increases length of intensive care unit stay and mortality rate.

Opportunistic infections associated with immunosuppressive treatments for inflammatory bowel disease pose an important safety concern. Here we report the case of a patient with active ulcerative colitis and cryptococcal pneumonia who was treated with vedolizumab combined with fuconazole.

Methotrexate (MTX) is a chemotherapy and immunosuppressive agent widely used to treat cancer, autoimmune diseases in children and adult patients, and ectopic pregnancy. However, MTX is highly toxic to the liver, kidney, and nervous system. This study aimed to quantify the concentration of MTX in human plasma using high-performance liquid chromatography (HPLC).

Post-transplantation anemia is common among renal transplant recipients (RTR). The most frequent causes are erythropoietin deficiency, acute allograft rejection, iron deficiency, hemolytic anemia, adverse effects of immunosuppressive therapy, and virus infection. Human parvovirus B19 (HPV B19) can cause persistent viremia and erythropoietin-resistant erythroid aplasia in immunosuppressed patients.

Thrombocytopenia, anasarca, fever, reticulin myelofibrosis/renal insufficiency, and organomegaly (TAFRO) syndrome is treated using corticosteroids and/or immunosuppressive agents as first-line therapy. We report the case of a 69-year-old female with TAFRO syndrome in which the patient presented multiple organ failure and steroid resistance, which was successfully treated using plasma exchange (PE) followed by rituximab.

Gemellsa morbillorum (G. morbillorum) is a Gram-positive facultative anaerobe and a known commensal organism of the oropharyngeal and gastrointestinal tracts. It is considered a rare cause of infections in humans.

Hepatic masses are relatively common findings, and the diagnostic approach often begins by identifying patient and mass characteristics that are risk factors for malignancy. Chronic immunosuppression is a known risk factor for various malignancies, and azathioprine in particular has been reported in association with solid and hematologic malignancies, including diffuse large B-cell lymphoma.

Pseudomonas aeruginosa is one of the top three causes of opportunistic infections in humans. Patients with a compromised immune system, due to immunosuppressive therapies or underlying diseases such as cancer, AIDS or the hereditary disease cystic fibrosis, are at risk of developing P. aeruginosa infection.

The pathogenesis of Parkinson’s disease (PD) involves degeneration of dopaminergic neurons, which is influenced by innate and adaptive immunity. IL-17 is a characteristic cytokine secreted by Th17 cells, which acts as a powerful stimulator of neutrophil migration and infiltration and promotes the secretion of inflammatory cytokines. General anesthesia and surgical stress induce immune and inflammatory responses that activate the immunosuppressive mechanism in the perioperative period.

Local anesthesia can reduce the response to surgical stress and decrease the consumption of opioids, which may reduce immunosuppression and potentially delay postoperative tumor recurrence. We compared paravertebral block (PVB) combined with general anesthesia (GA) and general anesthesia regarding their effects on postoperative pain and matrix metalloproteinase-9 (MMP-9) after video-assisted thoracoscopic surgery (VATS) lobectomy.

Epidural use can prevent peri-operative neuro-endocrine stress responses, mitigate pain after surgery, and reduce opioid use, which all lead to immunosuppression. Forty patients with gastric cancer were ultimately enrolled into the study. Patients who received general anaesthesia (GA group, n = 20) or a combination of general anaesthesia and peri-operative epidural use (EGA group, n = 20) were given intravenous analgesia or epidural analgesia, respectively.

Risk of over-immunosuppression or immunization may mitigate the overall and long-term renal outcomes of kidney transplant recipients (KTR) admitted to the ICU in the modern era but remain poorly described. Thus, there is an unmet need to better characterize the survival of KTR admitted to the ICU, but also the renal and immunological outcomes of survivors.

Blood transfusion can cause immunosuppression and lead to worse outcomes in patients with digestive tract malignancies; however, the specific mechanism behind this is not completely understood. One theory is that increased numbers of regulatory CD3+ CD4+ CD25+ FOXP3+ T cells (Tregs) and forkhead box protein-3 mRNA (FOXP3) expression in the blood after transfusion contribute to these outcomes.

Adenosine-to-Inosine (A-to-I) RNA editing is catalyzed by the adenosine deaminase acting on RNA (ADAR) family of enzymes, which induces alterations in mRNA sequence. It has been shown that A-to-I RNA editing events are of significance in the cell’s innate immunity and cellular response to viral infections. However, whether RNA editing plays a role in cellular response to microorganism/fungi infection has not been determined.

The patient was treated with infliximab and a regimen of amoxicillin 1 g three times a day. He had a marked response to the treatment after 2 weeks. The plan was to continue amoxicillin for at least 6 months with regular follow-up. Physicians should be aware that actinomycosis may be a cause of oral lesions in Crohn’s disease patient, particularly in immunosuppressed patient. Bacterial cultures and pathology are the cornerstones of diagnosis and should be performed in suspected cases to prevent misdiagnosis.

Pulmonary nocardiosis frequently develops as an opportunistic infection in cell-mediated immunosuppressive patients, and sometimes requires differentiation from pulmonary malignancy. Ectopic adrenocorticotropic hormone (ACTH) syndrome (EAS) is a neoplastic disorder which leads to impaired cell-mediated immunity, and is commonly associated with small cell lung cancer (SCLC).

Prednisone has been shown to reverse lung function declines in hypersensitivity pneumonitis patients without established fibrosis. Second line immunosuppressants like azathioprine and mycophenolate mofetil have a steroid sparing effect and improve DLCO. There is no published literature on the use of leflunomide in such patients.
