Tuberculosis IRIS: Pathogenesis, Presentation, and Management across the Spectrum of Disease.

ABSTRACT: Antiretroviral therapy (ART), while essential in combatting tuberculosis (TB) and HIV coinfection, is often complicated by the TB-associated immune reconstitution inflammatory syndrome (TB-IRIS). Depending on the TB disease site and treatment status at ART initiation, this immune-mediated worsening of TB pathology can take the form of paradoxical TB-IRIS, unmasking TB-IRIS, or CNS TB-IRIS. Each form of TB-IRIS has unique implications for diagnosis and treatment. Recently published studies have emphasized the importance of neutrophils and T cell subtypes in TB-IRIS pathogenesis, alongside the recognized role of CD4 T cells and macrophages. Research has also refined our prognostic understanding, revealing how the disease can impact lung function. While corticosteroids remain the only trial-supported therapy for prevention and management of TB-IRIS, increasing interest has been given to biologic therapies directly targeting the immune pathology. TB-IRIS, especially its unmasking form, remains incompletely described and more data is needed to validate biomarkers for diagnosis. Management strategies remain suboptimal, especially in the highly morbid central nervous system (CNS) form of the disease, and further trials are necessary to refine treatment. In this review we will summarize the current understanding of the immunopathogenesis, the presentation of TB-IRIS and the evidence for management recommendations.

Project description:BackgroundPeptic ulcer disease (PUD), once primary a surgical problem, is now medically managed in the majority of patients. The surgical treatment of PUD is now strictly reserved for life-threatening complications. Free perforation, refractory bleeding and gastric outlet obstruction, although rare in the age of medical management of PUD, are several of the indications for surgical intervention. The acute care surgeon caring for patients with PUD should be facile in techniques required for bleeding control, bypass of peptic strictures, and vagotomy with resection and reconstruction. This video procedures and techniques article demonstrates these infrequently encountered, but critical operations.Content video descriptionA combination of anatomic representations and videos of step-by-step instructions on perfused cadavers will demonstrate the key steps in the following critical operations. Graham patch repair of perforated peptic ulcer is demonstrated in both open and laparoscopic fashion. The choice to perform open versus laparoscopic repair is based on individual surgeon comfort. Oversewing of a bleeding duodenal ulcer via duodenotomy and ligation of the gastroduodenal artery is infrequent in the age of advanced endoscopy and interventional radiology techniques, yet this once familiar procedure can be lifesaving. Repair of giant duodenal or gastric ulcers can present a challenging operative dilemma on how to best repair or exclude the defect. Vagotomy and antrectomy, perhaps the least common of all the aforementioned surgical interventions, may require more complex reconstruction than other techniques making it challenging for inexperienced surgeons. A brief demonstration on reconstruction options will be shown, and it includes Roux-en-Y gastrojejunostomy.ConclusionSurgical management of PUD is reserved today for life-threatening complications for which the acute care surgeon must be prepared. This presentation provides demonstration of key surgical principles in management of bleeding and free perforation, as well as gastric resection, vagotomy and reconstruction.Level of evidenceVideo procedure and technique, not applicable.
