AT 2016 GRAPPA ANNUAL MEETING

VITALS

Key clinical point:Patients with psoriatic disease had a significantly higher prevalence of diabetes mellitus and some other endocrine comorbidities.

Major finding: In a univariate analysis, the risk for Cushing’s disease was notably higher among psoriatic arthritis patients, compared with controls (odds ratio, 5.31).

Data source: Retrospective, cross-sectional comparison of 3,161 patients with psoriatic arthritis and 31,610 matched controls.

Disclosures: Dr. Haddad, Dr. Coates, and Dr. Kavanaugh reported having no relevant financial disclosures.

The large, population-based cohort is a strength of the study. “We are now going back to see how many of these patients were seen by rheumatologists,” Dr. Haddad said. A lack of association with disease burden is a potential limitation, he added.

Thirty percent of patients were treated with biologics and about 67% with steroids. “That number treated with steroids seems high,” a meeting attendee commented. Dr. Haddad explained that it is the percentage ever treated with steroids, not necessarily currently on steroids.

In a separate session at the GRAPPA meeting addressing psoriatic disease treatment recommendations, an attendee asked about specific recommendations for comorbidities. For now, GRAPPA plans to include comorbidities within its overall recommendations, as it did in its most recent update, released in January 2016. A limited amount of data is a primary reason.

“As the evidence on comorbidities gets better, we may someday have separate recommendations for comorbidities,” said Laura Coates, MD, a clinical lecturer in rheumatology at the University of Leeds (England).

“The comorbidities are very important,” said Arthur F. Kavanaugh, MD, professor of medicine at the University of California, San Diego. “That’s trickier and deals with the international nature of GRAPPA. It’s hard to say, ‘Go see this specialist,’ because that might not be standard of care in that country.”

Dr. Haddad, Dr. Coates, and Dr. Kavanaugh reported having no relevant financial disclosures.

Pituitary Gland: Normal Function and Assessment

Posted on July 23, 2016 by MaryO

Abstract

This computer-based, interactive module introduces preclinical medical students to normal pituitary function and outlines its assessment. Solid understanding of these topics is requisite to learning clinical disorders of the pituitary.

Existing resources largely target learners at earlier or later stages of training; thus, we created this resource to address needs of medical students during a first- or second-year endocrine course. A module format was selected to promote interactive, independent learning.

Two cohorts of medical students completed the 40-minute module: 172 second-year students who had completed a year of basic sciences in the traditional curriculum and 180 foundation-phase students in a three-semester combined basic and clinical sciences curriculum (due to a change in the medical school curriculum at our institution). In both instances, the module was completed before start of clinical pituitary content. A static set of PowerPoint slides accompanied the module to facilitate note taking.

Test Your Knowledge slides were inserted to ensure grasp of key terms/concepts before moving to subsequent slides. A short question-and-answer session was held following module completion to clarify points of confusion. Students rated effectiveness of the module as 4.6 out of 5, commenting on its clarity, organization, high-yield nature, and utility in preparing for clinical material.

Faculty noted greater understanding of foundational pituitary principles and more engaging discussions. The percentage of pituitary-related questions answered correctly on the midterm exam increased.

Finally, success of the pituitary module prompted development of adrenal, thyroid, and parathyroid modules that now comprise the Endocrine Organs Introduction Series in our curriculum.

Educational Objectives

After completing this module, the learner will be able to:

  1. Describe the normal function and regulation of the pituitary gland, including names and actions of the anterior and posterior pituitary hormones.
  2. Understand the basic approach to laboratory assessment of the pituitary.
  3. Differentiate between anterior and posterior pituitary origin, function, and regulation.
  4. List the hormones produced by the pituitary gland.
  5. Discuss for each pituitary hormone: hypothalamic stimulating/inhibiting factors and their clinical uses, basic physiologic function, and regulation (feedback loop).
  6. Describe factors that affect growth hormone levels.
  7. Understand the tests for growth hormone excess and deficiency.
  8. Define a primary versus secondary endocrine disorder.

16 Years Old!

Posted on July 21, 2016 by MaryO

happybirthday-2015

It’s unbelievable but the idea for Cushing’s Help and Support arrived 16 years ago last night.  That’s a long time for anything online.

I was talking with my dear friend Alice, who ran a wonderful menopause site called Power Surge, wondering why there weren’t many support groups online (OR off!) for Cushing’s and I wondered if I could start one myself and we decided that I could.

The first website (http://www.cushings-help.com) first went “live” July 21, 2000 and the message boards September 30, 2000. Hopefully, with these sites, I’m making some helpful differences in someone else’s life!

The message boards are very active and we have weekly online text chats, occasional live interviews, local meetings, email newsletters, a clothing exchange, a Cushing’s Awareness Day Forum, podcasts, phone support and much more.

Whenever one of the members of the boards gets into NIH, I try to go to visit them there. Other board members participate in the “Cushie Helper” program where they support others with one-on-one support, doctor/hospital visits, transportation issues and more.

Of course, we now have a Facebook page and 2 groups.  Both are secret, so if you want to join, please email  or PM me for an invitation.

Other sites in the Cushing’s Help “Family”

GH therapy increases fracture risk in patients previously treated for acromegaly

Posted on July 16, 2016 by MaryO

van Varsseveld NC, et al. Pituitary. 2016;doi:10.1007/s11102-016-0716-3.

Adult patients with severe growth hormone deficiency previously treated for acromegaly saw an increased fracture risk after 6 years of growth hormone replacement therapy, whereas those previously treated for Cushing’s disease did not experience the same risk, according to a recent observational study.

Nadege C. van Varsseveld, MD, of the department of internal medicine at VU University Medical Center in Amsterdam, and colleagues analyzed data from 1,028 patients with previous nonfunctioning pituitary adenoma (NFPA; n = 783), acromegaly (n = 65) and Cushing’s disease (n = 180), identified through the Dutch National Registry of Growth Hormone Treatment in Adults, a nationwide, long-term surveillance study in patients with severe GH deficiency. Data were collected biannually from medical records through 2009. Baseline DXA measurements were available for 414 patients; 71 (17.1%) had osteoporosis at one or more of the measured sites; 147 (35.5%) had osteopenia.

During a mean follow-up of 5.2 years, researchers found that 166 of patients with previous NFPA were prescribed osteoporosis medications (21.3%), as were 69 patients with previous Cushing’s disease (38.5%) and 22 patients with previous acromegaly (33.4%). During follow-up, 39 patients experienced fractures (3.8%; 32 experiencing one fracture), including 26 patients in the previous NFPA group, eight patients in the previous Cushing’s disease group and five patients in the previous acromegaly group. The median time between baseline and first fracture was 2.4 years (mean age, 59 years).

Researchers found that fracture risk did not differ between groups before 6 years’ follow-up. Fracture risk increased in patients with previous acromegaly after 6 years’ follow-up, but not for those with previous Cushing’s disease vs. patients with NFPA. Results persisted after adjustment for multiple factors, including sex, age, fracture history and the extent of pituitary insufficiency.

The researchers noted that patients with previous Cushing’s disease were younger and more often women and had a greater history of osteopenia or osteoporosis, whereas patients with acromegaly had a longer duration between tumor treatment and the start of GH therapy and were treated more often with radiotherapy.

“During active acromegaly, increased bone turnover has been observed, but reported effects on [bone mineral density] are heterogeneous,” the researchers wrote. “It is postulated that cortical BMD increases, whereas trabecular BMD decreases or remains unaffected.

“The increased fracture risk in the present study may be a long-term effect of impaired skeletal health due to previous GH excess, even though this was not reflected by an increased occurrence of osteopenia or osteoporosis in the medical history,” the researchers wrote. – by Regina Schaffer

Summary

Primary hyperaldosteronism is one of the most common causes of secondary hypertension but clear differentiation between its various subtypes can be a clinical challenge.

We report the case of a 37-year-old African-American woman with refractory hypertension who was admitted to our hospital for palpitations, shortness of breath and headache. Her laboratory results showed hypokalaemia and an elevated aldosterone/renin ratio. An abdominal CT scan showed a nodule in the left adrenal gland but adrenal venous sampling showed elevated aldosterone/renin ratio from the right adrenal vein. The patient began a new medical regimen but declined any surgical options.

We recommend clinicians to maintain a high level of suspicion to consider the less common subtypes of primary hyperaldosteronism, especially given the fact that the management greatly varies.
