Hospital Course

  • Admitted to the ICU for management of thyrotoxicosis and started on empiric antibiotics for sepsis
  • Blood cultures positive for MRSA; TTE showed tricuspid valve endocarditis
  • Endocrinology was consulted and started:
  • Methimazole
  • Propranolol
  • Hydrocortisone
  • Cholestyramine
  • Patient endorsed anterior neck pain, palpitations, diaphoresis and heat intolerance for 2-3 days before presentation
  • Thyroid receptor antibody (TRAb) was negative, ruling out Grave’s disease
  • Methimazole was stopped
  • TPO antibody was negative, ruling out Hashimoto’s thyroiditis
  • Repeat thyroid ultrasound continued to show evidence of thyroiditis
  • Thyroiditis attributed to septicemia/endocarditis/systemic inflammation
  • Patient’s condition gradually improved and steroids were tapered

SLIDE 20

Thyroid Storm

  • Thyroid storm is a rare, life-threatening manifestation of thyrotoxicosis
  • 20-30% mortality rate
  • Affecting only 1% of thyrotoxic patients
  • Most common in patient’s with an underlying hyperthyroid state (Grave’s Disease, toxic multinodular goiter or

solitary toxic adenoma) who have an inciting event

  • Thyroid or non-thyroidal surgery
  • Infection
  • Trauma
  • Acute iodine load
  • Childbirth
  • Irregular use or discontinuation of anti-thyroid drugs (ex. methimazole, propylthiouracil)
  • Very few documented cases of thyroid storm in the setting of subacute thyroiditis

slide-21
SLIDE 21

Presentation

  • Patients present with severe signs/symptoms of thyrotoxicosis
  • Hyperpyrexia
  • Tachycardia
  • Heart failure
  • Hypotension
  • Diarrhea
  • Confusion/delirium
  • Anxiety/agitation
  • Physical exam
  • Goiter may or may not be present
  • Labs
  • Suppressed TSH, elevated Free T3/T4
  • Degree of Free T3/T4 elevation doesn’t necessarily correlate with severity of symptoms

SLIDE 22

Pathogenesis

  • Excess release of circulating thyroid hormones
  • Mechanism of hormone release differs depending on underlying hyperthyroid condition
  • Ex. Graves Disease, subacute thyroiditis, toxic multinodular goiter etc.

22

slide-23
SLIDE 23

Differential Diagnosis

  • Drug intoxication
  • Hypertensive emergency/hypertensive encephalopathy
  • Infection/sepsis
  • Neuroleptic malignant syndrome
  • Pheochromocytoma
  • Psychosis

  • Diagnosis is based on signs/symptoms of thyroid storm in

individuals with suppressed TSH and elevated Free T3/T4

  • The Burch-Wartofsky score is used to aid in the diagnosis
  • Scoring system:
  • < 25: thyroid storm unlikely
  • 25-44: impending thyroid storm
  • > 45: highly suggestive of thyroid storm
  • In this case, the Burch-Wartofsky score was 75

Diagnosis

slide-25
SLIDE 25

Workup

  • Labs
  • TSH, Free T3, Free T4
  • TSI or TRAb
  • Imaging
  • Thyroid ultrasound
  • CT neck soft tissue
  • Radioiodine uptake and scan

25

slide-26
SLIDE 26

Treatment

  • Patients require management in the ICU
  • Management includes:
  • Beta-blockers
  • Management of signs/symptoms related to increased adrenergic tone
  • Thionamides (methimazole or propylthiouracil)
  • Decrease synthesis and peripheral conversion of thyroid hormones
  • Glucocorticoids
  • Reduce peripheral conversion of T4 to T3 conversion
  • Promote vasomotor stability
  • Reduce inflammation (if present)
  • Bile acid sequestrants
  • Decrease enterohepatic recycling of thyroid hormones
  • Iodine (iodinated contrast or iodine tablets)
  • To be given after administration of anti-thyroid medications to prevent worsening of thyrotoxicosis
  • Decrease release of T3 and T4 from the thyroid

26

slide-27
SLIDE 27

Subacute Thyroiditis

  • Inflammation of the thyroid usually in the setting of viral illness or a post-viral inflammatory process
  • Pathogenesis: destruction of thyroid follicles and proteolysis of thyroglobulin causing release of T3 and T4
  • Presentation
  • Anterior neck pain
  • Diffuse goiter with tenderness to palpation
  • Signs/symptoms of hyperthyroidism/thyrotoxicosis with associated laboratory abnormalities
  • Thyrotoxicosis is usually mild
  • Severity of signs/symptoms don’t necessarily correlate with degree of lab abnormalities
  • Imaging
  • Ultrasound: hypoechoic appearance, may be normal or enlarged
  • Radioiodine uptake and scan: low uptake in the hyperthyroid phase
  • Treatment:
  • Pain control and beta blockers
  • Thionamides are not indicated
  • Clinical course
  • Hyperthyroid  Euthyroid  Hypothyroid  Recovery

two days, total net negative - 13.8 L since admission, wt 244

  • 23.5 L by end of

admission, wt 221 Patient either Euvolemic v.

  • Hypovolemic. Likely due

Cardio-Renal Syndrome Pathophysiology

 Complex interaction between Hemodynamics, RAAS, Sympathetic, HPA Axis,

Vasopressin, and Inflammation

 Cardiac output is reduced, resulting in venous systemic pressure elevation

which is transmitted to the kidneys/other organs, which have impaired perfusion and are so damaged. Reduced cardiac output also reduces perfusion to organs

 RASS, Vasopressin, HPA and local/systemic inflammation result, and continue

in a downward spiral perpetuating volume overload and end organ damage

 These patients have a narrow volume status, BP status and so diuretic window  Diuresis can is needed and may result in improvement, maintenance, or

worsening of creatinine initially (but is still needed regardless)

 These patients are often diuretic resistant

challenge

 Tolvaptan (when hyponatremic, infrequently used)  Vasodilators (i.e. isordil/hydralazine, nipride drip, avoid ACEi 2/2 AKI)  Inotropes (i.e. dobutamine, avoid milrinone 2/2 AKI)  Swan-Ganz (idk why we didn’t do this…)  CVP (at least we did this)  Echo

, gout flare, and dehydration. He is living at home; family is bringing him to appointments.

 Is seeing Cardiology, Nephrology and Pulmonology
