RESUMO
Thyrotoxic crisis (thyroid storm) is a severe form of hyperthyroidism. It has a wide range of symptoms, including cardiovascular manifestations that can be life-threatening and require prompt management. Cardiac manifestations of thyroid storm include hypertension, tachycardia, congestive heart failure, cardiac ischemia, and atrial fibrillation. Standard therapeutic approaches of thyroid storm are based on the use of thionamides, corticosteroids, and nonselective beta-blockers to inhibit thyroid hormone synthesis and release while also blocking thyroxin's peripheral effects. This approach is an effective measure in the management of these manifestations. However, when a patient fails to respond to conventional therapy, or there is end organ damage and surgery is not feasible, therapeutic plasma exchange (TPE) is a life-saving measure. Here, we report a case of a 27-year-old female who is known to have hyperthyroidism, but she was not compliant with her medication. She presented with symptoms of hyperthyroidism and was found to have a thyroid storm with refractory atrial fibrillation. Despite the effort to control her symptoms, she developed cardiac arrest, and after 15 minutes of cardiopulmonary resuscitation, she was revived. Amiodarone, beta-blockers, and cardioversion failed to improve the patient's status, and her condition deteriorated. So, we decided to use TPE, and she received three sessions in total. After the first session of TPE, her rhythm converted to sinus rhythm, and her heart rate was controlled to less than 100 beats per minute. She showed dramatic improvement clinically and biochemically. In conclusion, cardiac complications are potentially lethal complications of thyroid storm. Prompt restoration of a normal thyroid state can reverse these complications. When conventional therapy fails to ameliorate symptoms or organ deterioration is rapid and severe, TPE can be a safe and effective measure.
RESUMO
OBJECTIVE: To mitigate the spread of COVID-19, Saudi Arabia implemented a nationwide lockdown that lasted for approximately five months. Due to the limited availability of telemedicine in Saudi Arabia, many people with diabetes (PWD) lost access to diabetes care services during the lockdown period. Here, we examined the impact of lockdown on cardiometabolic health in PWD and how this may have differed between those who utilized diabetes telemedicine during lockdown versus those who did not. METHODS: Hemoglobin A1C (A1C), body weight, lipid, and other cardiometabolic parameters were retrospectively reviewed in 384 PWD who attended routine clinic visits in the pre-lockdown (September 2019 to March 2020) and post-lockdown (Aug to Dec 2020) periods. Changes in cardiometabolic parameters from pre- to post-lockdown were compared across 3 groups according to the type of visit that they had during lockdown (April to July 2020): "no visit" (n = 215), "in-person" visit (n = 44), or "virtual" visit (n = 125). The virtual visits in our institution followed a simplified protocol that utilized technological tools readily available to most PWD and clinicians. RESULTS: PWD who attended "virtual" visits during lockdown were the youngest and most likely to have type 1 diabetes; followed by those who attended "in-person" visits and those who had "no visit". A significant reduction in A1C from pre- to post-lockdown periods was noted in PWD who attended a "virtual visit" (9.02 to 8.27%, respectively, p < 0.01) and those who attended an "in-person" visit (9.18 to 8.43%, respectively, p < 0.05) but not in those who had "no visit" (8.75 to 8.57%, p > 0.05). No significant changes were noted in serum glucose, blood pressure, or lipid parameters during the lockdown in any of the groups. CONCLUSION: Simplified telemedicine visits, including real-time audio calls, were as effective as in-person visits in improving glycemic control in PWD during the lockdown period in a country where telemedicine infrastructure was not well-established. Older adults and those with type 2 diabetes were less likely to utilize telemedicine; suggesting a potential risk of digital divide that warrants greater attention in the future.
