RT Journal Article SR Electronic T1 Miliary tuberculosis and herpes pharyngitis after a trip to a developing country: dangers of biologics JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr-2018-224459 DO 10.1136/bcr-2018-224459 VO 2018 A1 Patel, Sanket A1 Weaver, Martin Douglas A1 Roy, Satyajeet YR 2018 UL http://casereports.bmj.com/content/2018/bcr-2018-224459.abstract AB The use of biologic drugs has expanded since its introduction in the late 1990s. With growing medical use and newer biologic drugs in development, opportunistic infections like Mycobacterium tuberculosis remain important adverse effects. It carries major public health concerns, yet evidence-based clinical guidelines for more routine interval screening in patients taking immunosuppressants and exposed to tuberculosis (TB) are lacking. We illustrate a case of an elderly Indian-born man living in the USA with psoriatic arthritis who was on adalimumab for 10 years. He presented with disseminated TB and herpes simplex virus type 1 (HSV-1) pharyngitis, a year after an innocuous trip to India. Our case draws attention to the adverse effects of biologic drugs and highlights the importance of regular rescreening for a high-risk population. As the use of biologic treatment increases, physicians must be vigilant in more frequent screening, monitoring and identifying related opportunistic infections, notably M. tuberculosis infections.
