  • Targeting immune evasion via immune checkpoint pathways has changed the treatment paradigm in cancer. Since CTLA-4 antibody was first approved in 2011 for treatment of metastatic melanoma, eight immune checkpoint inhibitors (ICIs) centered on PD-1 pathway blockade are approved and currently administered to treat 18 different types of cancers. The first part of the review focuses on the history of CTLA-4 and PD-1 discovery and the preclinical experiments that demonstrated the possibility of anti-CTLA-4 and anti-PD-1 as anti-cancer therapeutics. The approval process of clinical trials and clinical utility of ICIs are described, specifically focusing on non-small cell lung cancer (NSCLC), in which immunotherapies are most actively applied. Additionally, this review covers the combination therapy and novel ICIs currently under investigation in NSCLC. Although ICIs are now key pivotal cancer therapy option in clinical settings, they show inconsistent therapeutic efficacy and limited responsiveness. Thus, newly proposed action mechanism to overcome the limitations of ICIs in a near future are also discussed.

  • Antiphospholipid syndrome (APS) is an acquired systemic autoimmune disorder characterized by a combination of clinical criteria, including vascular thrombosis or pregnancy morbidity and elevated antiphospholipid antibody titers. It is one of the causes of deep vein thrombosis and pulmonary embolism that can be critical due to the mortality risk. Overall recurrence of thromboembolism is very low with adequate anticoagulation prophylaxis. The most effective treatment to prevent recurrent thrombosis is long-term anticoagulation. We report on a 17-year-old male with APS, who manifested blue toe syndrome, deep vein thrombosis, pulmonary thromboembolism, and cerebral infarction despite adequate long-term anticoagulation therapy.

  • Objective: The root bark of Ulmus davidiana var. Japonica (Ulmi Radicis cortex, URC) is a medicinal herb used for promoting diuresis and treating dampness. In Korea, URC has long been used as an efficacious therapy for inflammation, burns, frostbite and skin diseases such as eczema and psoriasis. Methods: In the present study, we used 1-fluoro-2,4-dinitrofluorobenzene (DNFB)-induced contact dermatitis (CD) mouse model to investigate the anti-allergic and the anti-inflammatory effects of URC on skin lesion, histopathological changes and specific antibody production. Results: URC treatment, 10 mg/mL, effectively inhibited skin lesions induced by repeated paintings with DNFB. In the histopathological observation, topical application of URC inhibited spongiosis. In addition, URC lowered the production levels of total immunoglobulin and IgG2a in serum. Conclusion: These data indicate that URC has an anti-inflammatory effect that produces an improvement of skin lesions in CD mice.

  • Diffuse alveolar hemorrhage (DAH) is a life-threatening and medical emergency that can be caused by numerous disorders and presents with hemoptysis, anemia, and diffuse alveolar infiltrates. Early bronchoscopy with bronchoalveolar lavage is usually required to confirm the diagnosis and rule out infection. Most cases of DAH are caused by capillaritis associated with systemic autoimmune diseases such as anti-neutrophil cytoplasmic antibody-associated vasculitis, anti-glomerular basement membrane disease, and systemic lupus erythematosus, but DAH may also result from coagulation disorders, drugs, inhaled toxins, or transplantation. The diagnosis of DAH relies on clinical suspicion combined with laboratory, radiologic, and pathologic findings. Early recognition is crucial, because prompt diagnosis and treatment is necessary for survival. Corticosteroids and immunosuppressive agents remain the gold standard. In patients with DAH, biopsy of involved sites can help to identify the cause and to direct therapy. This article aims to provide a general review of the causes and clinical presentation of DAH and to recommend a diagnostic approach and a management plan for the most common causes.

  • Kawasaki disease (KD) was first described by Dr. Tomisaku Kawasaki in his 1975 study, published in Pediatrics. Its pathogenesis is still not clearly understood. Early diagnosis and treatment are very important to preventing concomitant coronary artery complications. Most KD patients respond well to the standard treatment of aspirin and intravenous immunoglobulin; however, some of them are refractory to the standard treatment, and so adjuvant therapies with corticosteroids and anti-tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) antibody are necessary. In this article, the author reviews and summarizes the most recent literature on the treatment of refractory KD.

  • Crohn's disease is a chronic inflammatory disorder of the gastrointestinal tract and characterized by relapsing and remitting episodes, with progression over time to complications of stricture, fistulas, or abscesses. The etiology is unknown, although the common opinion is that the disease arises from a disordered immune response to the gut contents in genetically predisposed individuals. Infliximab is a mouse-human chimeric antibody against tumor necrosis factor ${\alpha}$, and has proven to be effective in active Crohn's disease for both induction and maintenance therapy. Despite the growing experience with infliximab in Crohn's disease, optimal treatment strategies still need to be determined. The purpose of this review is to summarize the current knowledge on the use of infliximab in Crohn's disease and to discuss the yet-unsolved issues.

  • An often overlooked issue in the field of adenovirus (Ad)-mediated cancer gene therapy is its limited capacity for effective systemic delivery. Although primary tumors can be treated effectively with intralesional injection of conventional Ad vectors, systemic metastasis is difficult to cure. Systemic administration of conventional naked Ads leads to acute accumulation of Ad particles in the liver, induction of neutralizing antibody, short blood circulation half-life, non-specific biodistribution in undesired organs, and low selective accumulation in the target disease site. Versatile strategies involving the modification of viral surfaces with polymers and nanomaterials have been designed for the purpose of maximizing Ad anti-tumor activity and specificity by systemic administration. Integration of viral and non-viral nanomaterials will substantially advance both fields, creating new concepts in gene therapeutics. This review focuses on current advances in the development of smart Ad hybrid nanocomplexes based on various design-based strategies for optimal Ad systemic administration.

  • Hundreds of drugs have been implicated as the causes of antibody-mediated thrombocytopenia. Naproxen is a commonly used nonsteroidal anti-inflammatory drug, and it is generally considered to be safe with few hematological side effects such as thrombocytopenia. In this case, severe thrombocytopenia associated with petechia and epistaxis appeared after initiation of naproxen therapy in the 59-year-old man. We report here on a case of severe thrombocytopenia that was recognized at 10 days after the use of naproxen, and the patient rapidly recovered to a normal platelet count without bleeding symptoms or any complications, although immunoglobulin or steroid was not used.

  • Systemic lupus erythematosus is a disease of unknown etiology that affects many organ system and is characterized by the presence of multiple autoantibodies that participated in immunology mediated tissue injury. A 36 years-old female patient was admitted to ward due to high fever and erythematous rash on face and hole body. She exhibited itching sense, joint pain, nausea, fatigue, sensitivity to light. The homatologic finding revealed anemia, decrease of lymphocyte, low platelet count, but LE cell, Anti nuclear antibody(ANA) were negative. In the point of Differentiation of Syndrome(辨證), SLE can be thought to be a category of Seasonal febril disease(溫病). This subject diagnosed as Domination of intense evil heat(熱毒熾盛), and was administrated with Chungonpadocyem-gamibang(淸瘟敗毒飮加味方). The clinical and laboratory findings of our patient were improved by herb medication, acupuncture therapy and general supportive measure.
