Refractory Chest Pain in Mild to Moderate Coronavirus Disease 2019 Successfully Treated with Saikanto, a Japanese Traditional Medicine.

Coronavirus disease 2019 (COVID-19) causes a variety of pain symptoms in the acute phase. Severe chest pain suddenly occurs even without abnormalities on examination and is sometimes refractory to analgesics. Such pain is a clinical concern in care facilities with limited resources, and this is the first report on the use of saikanto for its treatment. In Miyagi Prefecture, Japan, COVID-19 patients with mild symptoms were admitted to a hotel that operated as an isolation facility, and their symptoms were observed. In this article, we report four cases in which chest pain comorbid with mild to moderate COVID-19 was successfully treated with saikanto, a traditional Japanese (Kampo) medicine. The patients presented with chest pain and underwent medical examination at the facility. Two patients had severe chest pain refractory to acetaminophen. Critical cardiopulmonary diseases were ruled out in all the patients, and three patients had features of pneumonia on chest radiograph. Medications, including saikanto, were administered to the patients. The patients' chest pain and other symptoms improved 1-4 days after the administration of saikanto, and they left the care facility without hospitalization. The cause of the chest pain experienced by these patients is unclear, but we speculate that it could be minimal pleural inflammation or neuropathy. Previous pharmacological studies have suggested anti-inflammatory and analgesic properties of the crude drugs that constitute saikanto. This case report suggests that saikanto could be a treatment option for chest pain refractory to analgesics in patients with mild to moderate COVID-19.

Response to Glucocorticoid Therapy in Patients with Mild to Moderate Coronavirus Disease 2019 at a Japanese Care Facility.

The fifth wave of the coronavirus disease 2019 (COVID-19) pandemic caused by delta variant infection depleted medical resources, and the Japanese government announced glucocorticoid use for outpatients. An appropriate outpatient-glucocorticoid treatment for COVID-19 has not been established; therefore, we created treatment manuals with indications for glucocorticoid administration in a care facility adequately equipped to manage patients with mild to moderate COVID-19. Thirty-eight patients (24 males, 14 females; mean age 40.5 ± 11.8 years) were treated with glucocorticoids from August 1 to October 1, 2021 [COVID-19 staging, mild (n = 1), moderate I (n = 19), and moderate II (n = 18)]. Patients were treated with 6.6 mg/day d.i.v. or 6 mg/day p.o. dexamethasone, or 20-30 mg/day p.o. prednisolone. The median (25th-75th percentile) number of days from the date of onset to glucocorticoid administration was 8.0 days (7.0-11.25 days). While 24 patients were hospitalized, the condition of 14 improved without hospitalization. The median number of days from glucocorticoid administration to hospitalization was 1.0 day (range, 1.0-1.0 day). In the non-hospitalized patients, the median number of days of glucocorticoid administration was 5.0 days (5.0-5.25 days). The mean number of days from glucocorticoid administration to discharge from the care facility for non-hospitalized patients was 8.4 ± 3.3 days. The adverse reactions among non-hospitalized patients included insomnia (n = 1) and mild liver dysfunction (n = 3). The present method of glucocorticoid administration can be safely used for patients with COVID-19 in care facilities.

Treatment of COVID-19-Related Olfactory Disorder Promoted by Kakkontokasenkyushin'i: A Case Series.

Olfactory disorders are one of the characteristic symptoms of the coronavirus disease of 2019 (COVID-19), which causes infection and inflammation of the upper and lower respiratory tract. To our knowledge, there are no treatments for COVID-19-related olfactory disorder. Here, we report five olfactory disorder cases in COVID-19, treated using the Japanese traditional (Kampo) medicine, kakkontokasenkyushin'i. We treated five patients with mild COVID-19 at an isolation facility using Kampo medicine, depending on their symptoms. Patients with the olfactory disorder presented with a blocked nose, nasal discharge or taste impairment. Physical examination using Kampo medicine showed similar findings, such as a red tongue with red spots and sublingual vein congestion, which presented as blood stasis and inflammation; thus, we prescribed the Kampo medicine, kakkontokasenkyushin'i. After administration, the numeric rating scale scores of the smell impairment improved within 3 days from 9 to 3 in case 1, from 10 to 0 in case 2, from 9 to 0 in case 3, from 5 to 0 in case 4, and from 9 to 0 within 5 days in case 5. Following the treatment, other common cold symptoms were also alleviated. Kakkontokasenkyushin'i can be used for treating nasal congestion, rhinitis, and inflammation in the nasal mucosa. The olfactory disorder in COVID-19 has been reportedly associated with inflammation and congestion, especially in the olfactory bulb and olfactory cleft. Kakkontokasenkyushin'i may be one of the treatment alternatives for the olfactory disorder with rhinitis in patients with COVID-19.
