Advances in Hormone Replacement Therapy for Adult Adrenal Insufficiency / 罕见病研究

Adrenal insufficiency is a disease characterized by insufficient secretion of adrenocortical hormones, usually treated with glucocorticoid replacement therapy. The routine drugs have two forms-short-acting and long-acting. The shorter one should be taken 2-3 times a day resulting hormone level of patients fluctuating greatly within a day. Although long-acting drugs reduce the frequency of administration, it is easy to lead to excessive replacement, resulting in adverse effects on metabolism. New alternative treatments for adult patients have emerged, including modified-release hydrocortisone and hydrocortisone subcutaneous infusion pumps. In this review, we briefly introduce these new therapies, emphasizing the pharmacodynamics and pharmacokinetics of the replacement, the effects on metabolism and drug safety, aiming at contributing to the future clinical practice.

Perfusión de furosemida subcutánea como tratamiento paliativo en insuficiencia cardiaca refractaria / Subcutaneous furosemide infusion as palliative treatment in refractory end-stage heart failure

Resumen En la insuficiencia cardiaca terminal los síntomas predominantes habitualmente están relacionados con la congestión; sin embargo, la resistencia a diuréticos vía oral es frecuente y necesita tratamiento parenteral para paliar los síntomas. La administración intravenosa de furosemida requiere hospitalización o asistencia hospitalaria, lo que supone un deterioro significativo de la calidad de vida de pacientes en fases avanzadas de la enfermedad. La administración subcutánea continua de furosemida mediante infusor elastomérico es una técnica eficaz con baja tasa de complicaciones graves que permite la administración de diurético parenteral en el ámbito domiciliario, y evita la necesidad de hospitalizar. A pesar de que esta modalidad de tratamiento no está aceptada en ficha técnica y requiere más estudios que precisen su indicación, puede suponer un recurso adecuado para pacientes seleccionados. Se presenta el caso de una paciente con insuficiencia cardiaca avanzada, síntomas congestivos y ausencia de respuesta a tratamiento deplectivo vía oral, tratada con perfusión continua subcutánea domiciliaria de furosemida mediante infusor elastomérico de forma prolongada.

Abstract In end-stage heart failure the predominant symptoms are usually associated with congestion. However, the resistance to oral diuretics is common and requires parenteral treatment to alleviate the symptoms. The intravenous administration of furosemide requires hospital admission or hospital care. This leads to a significant decrease in the quality of life of patients in advance stages of the disease. The continuous subcutaneous infusion of furosemide using an elastomeric pump is an effective technique, with a low rate of serious complications that allows a parenteral diuretic to be administered in the home environment and thus avoiding the need for hospital admission. Despite this mode of treatment not being indicated in the drug data sheet, and requires more studies that specify its indication, it may be a suitable recourse for selected patients. It is presented a case of a patient with advanced heart failure, congestive symptoms, and a lack of response to oral diuretics treatment, and then treated with a continuous and prolonged subcutaneous infusion of furosemide at home using an elastomeric infusion pump.

The Effect of Continuous Subcutaneous Infusion of Chlorpromazine on Refractory Delirium in Advanced Cancer: Retrospective Study

Context: Delirium in cancer is often difficult to control and refractory when haloperidol is invalid which is considered standard therapy. We need second and subsequent-line therapy to reduce hyperactivity and not to over-sedation for refractory delirium. Objectives: To investigate the efficacy and safety of continuous subcutaneous infusion chlorpromazine on delirium refractory to first-line antipsychiatric medications in advanced cancer palliative care setting. Method: The study population consisted of patients who received continuous subcutaneous infusion chlorpromazine for delirium at two certified PCU. Primary endpoint was the proportion of patients who showed improvements in delirium severity by Delirium Rating Scale Revised 98 score of less than 13 or decrease from baseline and maintained the ability to communicate coherently by Communication Capacity Scale Item-4 score of 2 or less. Secondary outcome were the Nursing Delirium Screening Scale subscale score, and injection site reactions evaluated according to the Common Terminology Criteria for Adverse Events. These outcome measures were assessed at baseline, 48 hours and 7 days after the start of the study. Result: Among eighty-four patients, sixty were positive responders (71.4%, 95% CI [61–80]). The mean CCS Item-4 scores significantly decreased from the baseline value of 1.48 (range 0–3) to 1.03 (range 0–3) at post-treatment (p<0.001). Grade 2 or higher injection site reactions were observed in 1 patient (1.2%, 95% CI [0–7]). Conclusion: Our study suggested that continuous subcutaneous infusion chlorpromazine could improve refractory delirium symptoms and patients’ communication capabilities. Although most of the skin disorders observed in association with chlorpromazine were mild, their incidence rates were relatively high, suggesting the need for careful monitoring.

Establishment of a liaison system for continuous opioid infusion using a patient-controlled analgesia pump at home

In our medical district, home care physician-led liaison system has not yet been established for pain relief using a patient-controlled analgesia（PCA）pump. Therefore, it has been difficult to perform continuous opioid infusion at home. We investigated the liaison system based on our experience with breast cancer patients in whom oral drug administration became difficult during palliative care at home and thus continuous opioid subcutaneous infusion was started in cooperation with a palliative care hospital team and based on the discussion among home care study group physicians of the medical association. Based on the results of our study, we established the system called“Home PCA Raku-raku（Easy）Pack”that are characterized by the following：（1）opioids are prescribed by a home care physician；（2）a certified cancer pain management nurse accompanies a nurse to visit the patients’ home, assesses their conditions, and changes the drug solution；（3）the pump rental fee is paid by the home care physician, and the cost of consumables is paid by the hospital；and（4）the home care physician calculates the fee for home management of malignant tumors, and the hospital calculates the collaborative medical management fee and the visiting nursing management fee. This system was applied to 6 patients during a period of approximately 2 years. The result of a questionnaire survey for home care physicians and visiting nurse stations using this system showed that the system was generally beneficial.

Ceftriaxone subcutaneous infusion at palliative care unit

Ceftriaxone is one of the easily administrative antibiotics, but little is known about their role in palliative care settings. The aim of this study is to show the effect and the safety of ceftriaxone subcutaneous infusion to infection among advanced cancer patients. Consecutive patients who received ceftriaxone subcutaneous infusion at the Seirei Hospice from January 2013 to January 2014 were enrolled in this retrospective analyses. Primary outcome was the response rate of ceftriaxone, determined by improvement of symptoms within 3 days of ceftriaxone use. Secondary outcomes are inflammatory site reaction, and a comparison of the response rate between ceftriatone and other antibiotics. Among a total of 100 admitted patients, 10 patients used ceftriaxone subcutaneous infusion (4 for urinary tract infection, 4 for pneumonia, 2 for soft tissue infection). The response rate was 70% (95% confidence interval, 39－89). There was no inflammatory symptom at the insertion site observed. For comparisons, 16 patients used other antibiotics with the response rate of 74% (51－88).In conclusion, subcutaneous infusion of ceftriaxone can be useful in the treatment of infections of end－of－life cancer patients, and randomized controlled trial is promising.

Use of the On-Q system for pain management after robot - assisted endoscopic transaxillary thyroidectomy

BACKGROUND: The robot-assisted transaxillary approach to thyroid surgery is a novel method that has recently been used to improve patient safety and cosmetic outcomes. We evaluated post-operative pain, following robot-assisted endoscopic transaxillary thyroid surgery, and pain relief using a continuous wound perfusion system with local anesthetics. METHODS: In a control group of 25 female patients who underwent robot-assisted endoscopic transaxillary thyroidectomy, the post-operative pain scores and characteristics as well as analgesic use were monitored. Fifty female patients undergoing robot-assisted endoscopic transaxillary thyroidectomy were given the On-Q system. They were then randomly assigned to receive one of two different local anesthetic doses: Group I (0.25% Ropivacaine, n = 25); and Group II (0.375% Ropivacaine, n = 25). The pain score, pain site, analgesic requirements and side effects of each group were recorded during the 48 hour period post-surgery. RESULTS: Post-operative pain scores and analgesic demand were lower in the On-Q groups than in the control group. No difference was found between Group I and Group II. Until 6-12 hours after surgery, pain was mainly located in the axilla, while after 6-12 hours, the primary location of pain had a tendency to move to the neck. Pain scores gradually decreased in time for all patients. CONCLUSIONS: Patients who underwent robot-assisted endoscopic transaxillary thyroidectomy with an On-Q system injecting 0.25% ropivacaine had lower pain scores, showing the effectiveness of the system. As a potential pain blocker, continuous wound perfusion with the On-Q system attenuates side effects. This could lead to shortened hospital stays after robot-assisted endoscopic transaxillary thyroidectomy.

Both switching from a winged needle to a small plastic intravenous catheter and adding dexamethasone to continuous subcutaneous infusion (CSCI) successfully treated inflammatory skin changes caused by CSCI

<b>Purpose</b>: The continuous subcutaneous infusion (CSCI) is one of the most popular methods to reduce cancer pain. Inflammatory skin changes such as redness and induration are sometimes observed around the infusion site of the skin. Although dexamethasone is empirically added to a CSCI regimen to reduce such skin changes, little evidence on this practice has been available. We aimed to demonstrate the effectiveness of the CSCI protocol that we have been using for the treatment of skin changes. <b>Methods</b>: We prospectively observed the incidence of skin changes. When redness or induration at the injected site appeared, a winged needle was switched to a plastic intravenous catheter. When the redness or induration did not resolve with this needle change, dexamethasone was added to CSCI. <b>Result</b>: Sixty-six patients with cancer pain who underwent CSCI using a winged needle were enrolled in this study. The CSCI needles were switched from a winged needle to a plastic intravenous catheter in 20 out of 66 patients who revealed redness at a size of greater than 10 mm in diameter during CSCI. After this needle switch, the skin changes resolved in 15 out of 20 patients. Among the five patients who did not respond to the needle change, the skin changes resolved in three patients by dexamethasone (0.5∼1 mg/day) added to CSCI. <b>Conclusion</b>: These findings suggest that both switching from a winged needle to a small plastic intravenous catheter and adding dexamethasone to a CSCI regimen are effective in the treatment of inflammatory skin changes caused by CSCI.

Pain Management via a Subcutaneous Infusion of Ketamine in a Patient with Complex Regional Pain Syndrome: A case report / 대한통증학회지

Complex regional pain syndrome (CRPS), which is a syndrome that is defined by pain and sudomotor and/or vasomotor instability, is usually resistant to conventional treatment. Here, a case involving a 30-year-old male patient with CRPS type I who showed severe intractable right shoulder pain with allodynia and hyperalgesia despite being treated with oral medications, nerve blocks including thoracic sympathetic neurolysis, and spinal cord stimulation is described. The patient frequently visited the emergency room due to severe uncontrollable breakthrough pain. Although a favorable effect was observed in response to intermittent ketamine infusion therapies that were performed on an outpatient basis, acute exacerbation of pain occurred frequently during the night and could not be controlled. Therefore, subcutaneous ketamine infusion therapy using a patient-controlled analgesic system was attempted and found to effectively control acute exacerbation of pain during 6 weeks of infusion without serious complications.

Radiologic Placement of Subcutaneous Infusion Ports in Cancer Patients: Analysis of 45 Cases / 대한암학회지

PURPOSE: We undertook this study to evaluate the usefullness of radiologic placement of subcutaneous infusion ports (SIP). MATERIALS AND METHODS: Between August 1999 and May 2000 we performed 45 implantations of SIP in radiologic suite. Both sonography and fluoroscopy were used for venipuncture and to guide port insertion. We prospectively evaluated 45 systems in 45 patients with solid tumors. RESULTS: Median follow-up time was 189 days (61~352 days). Technical success rate is 100% without any venipuncture-related complications. Early complication rate within 30 days of procedure was 4.4%, including wound dehiscence (n=1) and pocket hematoma and local infection (n=1). Catheter-related infection rate was 6.7% and catheter-related venous thrombosis rate was 4.4%. Mean duration of catheter use was 208 96 days (total, 9,381 days). Overall port survival rate was 38.5%, and four systems (8.9%) were prematurely removed because of catheter tunnel infection (n=1), pocket infection (n=1), and central venous thrombosis (n=2). CONCLUSION: Radiologic placement of SIP had higher success rate and equal or lower complication rate compared with reported conventional surgical technique using anatomical landmarks. Moreover, clinical convenience, resulting from ease of scheduling could make it replace surgical method.
