Tobacco Associated Deaths in the USA

JAMA Internal Medicine reports that in the USA, those who smoke cigar, pipe, or cigarette have a significant overall  mortality risk, and a much highers cancer mortality risk compared to nonsmokers.

The National Longitudinal Mortality Study collected baseline survey data from 1985 through 2011 and included 357,420 participants reporting on their use of cigar, pipes, or cigarettes.

In this cohort there were a total of 51,150 recorded deaths.  All cause mortality was significantly increased in:

  • exclusive current cigarette smokers (HR 1.98; 95% CI, 1.93-2.02)
  • exclusive current cigar smokers (HR, 1.20; 95% CI, 1.03-1.38)

A significantly increased risk of tobacco-related cancer deaths (bladder, esophagus, larynx, lung, oral cavity, and pancreas CA) was seen in:

  • exclusive current cigarette smokers (HR, 4.06; 95% CI, 3.84-4.29)
  • exclusive current cigar smokers (HR, 1.61; 95% CI, 1.11-2.32)
  • exclusive current pipe smokers (HR, 1.58; 95% CI, 1.05-2.38)

For nondaily cigarette users, statistically significant associations were seen for deaths from:

  • lung cancer (HR, 6.24; 95% CI, 5.17-7.54),
  • oral cancer (HR, 4.62; 95% CI, 1.84-11.58),
  • circulatory death (HR, 1.43; 95% CI, 1.30-1.57),
  • cardiovascular death (HR, 1.24; 95% CI, 1.11-1.39),
  • cerebrovascular death (stroke) (HR, 1.39; 95% CI, 1.12-1.74),
  • COPD (HR, 7.66; 95% CI, 6.09-9.64) as well as for daily smokers.

Hydroxychloroquine Being Over-Dosed with New Guidelines?

Hydroxychloroquine retinopathy prevention guidelines have revised from ideal body weight-based dosing to actual body weight-based dosing; the question remains whether these have been adopted in clinical practice. A database of nearly 21,000 new HCQ users from a UK general population database studied HCQ dosing and use between 2007 and 2016. Specifically they examined whether users were subjected to excess HCQ dosing per ophthalmology guidelines (defined by exceeding 6.5 mg/kg of IBW and 5.0 mg/kg of ABW).

NSAID Use Around Conception Increases Miscarriage Risk

A study from the American Journal of Obstetrics & Gynecology analyzed pregnant women from the Kaiser Permanente healthcare system and compared newly pregnant women who took non-steroidal anti-inflammatory drugs or acetaminophen or neither showed that using NSAIDs around conception carried a more than four-fold higher risk of early miscarriage.

Could Measuring Drug Levels with TNF Treatment Hurt Your Patients?

Our colleagues in gastroenterology measure drug levels with certain biologics used in inflammatory bowel disease in order to increase the dose for optimal benefit if the patient has a low trough level (i.e. targeting drug level).

There have been GI trials with T2T with drug levels but they are not always suggesting that the strategy is superior to usual care. Also, this is really not a common practice in rheumatology.

Cancer Therapies Inducing Immune-Related Adverse Events (irAEs)

Recent shifts in the cancer treatment paradigm towards immune therapies has led to wide implementation of the novel immune check point inhibitors (ICI) in the treatment of multiple types of advanced cancer.

While being quite effective in oncology, these checkpoint inhibitors have led to the emergence of a quite unique spectrum of rheumatologic conditions presented under the umbrella of immune-related adverse events (irAEs).
