Still’s disease is an uncommon, systemic, autoinflammatory disease of uncertain cause. It is often misdiagnosed because of heterogeneous symptoms, including fever, rash, leukocytosis, and arthralgia.

A recent study suggests that reexpression of a protein found during fetal development plays a role in the suppression of immunity in early colorectal adenomas and cancers. Figure 1 from the article shows SOX17 and immune evasion in early colorectal cancer development. SRY-box transcription factor 17 (SOX17) plays a crucial role in fetal development (Panel A), including formation of the gut endoderm and the vascular system, but also endometrial embryo receptivity acting mainly by ensuring an immune-tolerant environment. In adults, SOX17 is usually epigenetically silenced, which enables immune surveillance through up-regulation of major histocompatibility complex (MHC) class I expression and the interferon-γ receptor. During the initial phases of colorectal cancer development (Panel B), LGR5-negative epithelial cells can reactivate the fetal SOX17 program and thus reduce the susceptibility of tumor cells to interferon-γ, down-regulate MHC class I expression, and suppress T-cell infiltration. Thus, an immune-suppressive environment is established, enabling tumor outgrowth.

The 𝘋𝘪𝘢𝘨𝘯𝘰𝘴𝘵𝘪𝘤 𝘢𝘯𝘥 𝘚𝘵𝘢𝘵𝘪𝘴𝘵𝘪𝘤𝘢𝘭 𝘔𝘢𝘯𝘶𝘢𝘭 𝘰𝘧 𝘔𝘦𝘯𝘵𝘢𝘭 𝘋𝘪𝘴𝘰𝘳𝘥𝘦𝘳𝘴, fifth edition, criteria for the diagnosis of neuroleptic malignant syndrome include exposure to a dopamine-blocking drug, severe muscular rigidity, fever, and at least two of the following features: diaphoresis, dysphagia, tremor, incontinence, an altered level of consciousness, mutism, tachycardia, elevated or labile blood pressure, leukocytosis, or an elevated serum creatine kinase level. In practice, the syndrome is easier to identify than this list of items suggests. The history, medication list, and context usually make it apparent that the patient has been exposed to a drug implicated in neuroleptic malignant syndrome, but this is not always evident, particularly with medications that are not used primarily for the treatment of psychosis or delirium.

Data from nonrandomized comparisons have suggested that survival might be better with long-term oxygen therapy used for 24 hours per day than with the typically recommended 15 hours per day. Data from randomized trials directly comparing these two durations of oxygen therapy are lacking. In the REDOX trial, researchers assessed hospitalization and mortality among patients with chronic severe hypoxemia who received long-term oxygen therapy for either 24 or 15 hours per day. 241 adults who were starting oxygen therapy for chronic severe hypoxemia at rest were randomly assigned to receive long-term oxygen therapy (LTOT) for either 24 or 15 hours per day. The primary outcome was a composite of hospitalization or death from any cause within 1 year. Among patients with severe hypoxemia, long-term oxygen therapy used for 24 hours per day, as compared with 15 hours per day, did not reduce the risk of hospitalization or death within 1 year.

The 2024 Albert Lasker Award for Basic Medical Research recognizes Dr. Zhijian (James) Chen for his elucidation of how DNA stimulates immune responses. Figure 1 from the article illustrates the cGAS–STING DNA sensing pathway. The cyclic GMP–AMP synthase (cGAS) enzyme binds to viral DNA, tumor DNA, or our own aberrant DNA. DNA binding activates cGAS to synthesize cyclic GMP–AMP (cGAMP) from ATP and GTP nucleotides. Bacteria also produce cyclic dinucleotides (CDNs). Bacterial cyclic dinucleotides and cGAMP bind to STING, a protein of the endoplasmic reticulum, which results in activation of a signaling pathway that stimulates the production of type I interferons. IRF3 denotes interferon regulatory factor 3, IκBα nuclear factor of κ light polypeptide gene enhancer in B cells inhibitor alpha, NF-κB nuclear factor κB, and TBK1 TANK binding kinase 1.

𝗖𝗼𝗻𝗱𝗶𝘁𝗶𝗼𝗻𝗶𝗻𝗴 is a term used to describe a course of treatment comprising one or more medications administered to patients before transplantation of allogeneic or autologous hematopoietic stem cells. Typically, radiation and alkylating agents such as busulfan that eliminate the recipient’s hematopoietic cells are given to “make space” for the transplanted cells. For most allogeneic transplant recipients, additional agents are given to eliminate immune cells and prevent immunologic rejection of the graft.

Case Record of the Massachusetts General Hospital: A 47-year-old man was admitted to the hospital because of confusion, pneumonia involving the right lower lobe, and acute kidney failure. The creatine kinase level was 28,581 U per liter. A diagnosis was made. Figure 2 from the case shows environmental sources, clinical manifestations, laboratory findings, and radiologic findings of legionella pneumonia. Transmission typically occurs through aerosolization from an environmental source. Inhalation and inoculation result in prodromal symptoms, including fever, malaise, and headache. Over the course of several days, a cough develops that may or may not be productive of purulent sputum. Altered mental status is frequently described with severe cases. Nonpulmonary symptoms, such as headache and gastrointestinal symptoms, may be severe and lead to misdiagnosis. Laboratory findings are consistent with severe community-acquired pneumonia and may show leukocytosis or leukopenia, elevated levels of liver enzymes, lactate dehydrogenase, and creatine kinase, and hyponatremia; however, these findings lack specificity. Radiologic findings nearly always include a consolidating pneumonia at the time of presentation. Extrapulmonary infection is rare and occurs almost exclusively in immunocompromised patients.

Price, MD, and Sanjat Kanjilal, MD, MPH, from Massachusetts General Hospital, Harvard Medical School, Harvard Pilgrim Health Care Institute, and Brigham and Women's Hospital: https://nej.md/3B9Fx7e

Most patients with newly diagnosed chronic myeloid leukemia (CML) are treated with one of four approved ATP-competitive tyrosine kinase inhibitors (TKIs): first-generation imatinib or second-generation nilotinib, dasatinib, or bosutinib. However, many patients switch treatments within the first year because of troublesome adverse effects. In the ASC4FIRST trial, researchers assessed the efficacy and safety of asciminib as compared with investigator-selected TKIs in patients with newly diagnosed CML. 405 patients were randomly assigned to receive either asciminib or an investigator-selected TKI: imatinib, nilotinib, dasatinib, or bosutinib. The two primary objectives of the trial were to compare the efficacy of asciminib with that of the investigator-selected TKIs considered together and with imatinib considered individually. The primary end point for both objectives was major molecular response (defined by BCR::ABL1 transcript levels ≤0.1% on the International Scale) at week 48. Asciminib showed superior efficacy and a favorable safety profile as compared with investigator-selected TKIs considered together, and with imatinib individually, in patients with newly diagnosed chronic myeloid leukemia. Whether asciminib is more effective than the second-generation TKIs is not clear.
