Background/Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) was recently proposed as an alternative disease concept to nonalcoholic fatty liver disease (NAFLD). We aimed to investigate the prognosis of patients with biopsy-confirmed MASLD using data from a multicenter study. Methods: This was a sub-analysis of the Clinical Outcome Nonalcoholic Fatty Liver Disease (CLIONE) study that included 1,398 patients with NAFLD. Liver biopsy specimens were pathologically diagnosed and histologically scored using the NASH Clinical Research Network system, the FLIP algorithm, and the SAF score. Patients who met at least one cardiometabolic criterion were diagnosed with MASLD. Results: Approximately 99% of cases (n=1,381) were classified as MASLD. Patients with no cardiometabolic risk (n=17) had a significantly lower BMI than patients with MASLD (20.9 kg/m2 vs. 28.0 kg/m2, P<0.001), in addition to significantly lower levels of inflammation, ballooning, NAFLD activity score, and fibrosis stage based on liver histology. These 17 patients had a median follow-up of 5.9 years, equivalent to 115 person-years, with no deaths, liver-related events, cardiovascular events, or extrahepatic cancers. The results showed that the prognosis for pure MASLD was similar to that for the original CLIONE cohort, with 47 deaths and one patient who underwent orthotopic liver transplantation. The leading cause of death was extrahepatic cancer (n=10), while the leading causes of liver-related death were liver failure (n=9), hepatocellular carcinoma (n=8), and cholangiocarcinoma (n=4). Conclusions Approximately 99% of NAFLD cases were considered MASLD based on the 2023 liver disease nomenclature. The NAFLD-only group, which is not encompassed by MASLD, had a relatively mild histopathologic severity and a favorable prognosis. Consequently, the prognosis of MASLD is similar to that previously reported for NAFLD.

The cause of dizziness is often phlegm-rheum, and most of them are treated with drugs, which eliminate excessive fluids. However, in recent years, the causes of dizziness have become diversified and complicated, and in some cases it is difficult to treat with general-purpose agents. This time, we present a case of chronic refractory dizziness successfully treated with goshakusan. The patient was a 70-year-old woman. She had wobbled while walking for 2 years, and consulted nearby doctors. No particular abnormality was pointed out, and oral treatment was performed, but there was no improvement. In our department, ryokeijutsukanto, hangebyakujutsutenmato, goreisan, hochuekkito, kamishoyosan, chotosan, and shinbuto were prescribed by the doctor at the first visit. However, there was no improvement, and the author took over the charge. We diagnosed her with orthostatic dysregulation and prescribed tofisopam, but her dizziness did not improve. We conducted oriental medical examination, and diagnosed that phlegm-rheum associated with food accumulation was the main pathological condition, and that qi stagnation and blood stasis were combined. After 16 weeks of administration of goshakusan, her dizziness improved.

Sleep disorders may be involved in unexplained dizziness. This time, we report 2 cases of dizziness with sleep disorders improved with keishikaryukotsuboreito. Case 1 is a 67-year-old woman. She had had vertigo attacks for 4 years, was very anxious about the attacks, had trouble falling asleep, and was aware of dizziness even between the attacks. After 4 weeks of administration of keishikaryukotsuboreito, her anxiety disappeared and she was able to sleep soundly. After 10 weeks, the lightheadedness disappeared and the medication was terminated at 17 weeks. Case 2 is a 38-year-old woman. She was exhausted because she had a personnel change in her workplace 3 months ago and she was concerned about many things. From 2 months ago, she had trouble falling asleep at night. After 2 weeks of administration of keishikaryukotsuboreito, she was able to sleep soundly. The dizziness disappeared after 6 weeks, and the medication was terminated at 10 weeks.

In cases of pulsatile tinnitus, the presence of organic disease should be suspected, and many of them can be treated once the cause is identified. However, there are idiopathic cases in which the cause cannot be identified, and there is no established treatment for them. Here, we report 2 cases in which Kampo medicine was effective for idiopathic pulsatile tinnitus. Case 1 was a 50-year-old man. He had been stressed for half a year due to the change of job title in his workplace, and he had left pulsatile tinnitus a month ago. We administered saikokaryukotsuboreito, and his tinnitus disappeared in a week. Case 2 was a 30-year-old woman. She gave birth 4 months ago, and after giving birth, she had less sleep and was tired and stressed. She started to notice right pulsatile tinnitus and dizziness from a month ago. We administered nyoshinsan, and her tinnitus and dizziness disappeared in 2 months. In both cases, they were aware of hot flashed on their face as a symptom of qi counterflow, and Kampo treatment improved the symptom together with pulsatile tinnitus. It is possible that blood flow in the head increased with qi counterflow, causing relative stenosis of the blood vessels in the head, leading to turbulence in the lumen of the blood vessels, and hearing pulsatile tinnitus.

We have reported cases of idiopathic sensorineural hearing loss treated with Japanese Kampo medicine in the past, but they all exhibited deficiency pattern. This time, we experienced cases of idiopathic sensorineural hearing loss, which exhibited medium pattern and excess pattern. Case 1 is a 57-year-old man. He had a chief complaint of ringing and hearing loss in his right ear from 3 days ago and was diagnosed with right idiopathic sensorineural hearing loss Grade3b. He exhibited medium pattern with liver qi depression and blood stasis, and was administered shosaikoto and keishibukuryogan. He was cured after 2 weeks. Case 2 is a 48-year-old man. He had a chief complaint of hearing loss in his right ear and dizziness from 2 days ago and was diagnosed with right idiopathic sensorineural hearing loss Grade4a. He exhibited excess pattern with liver qi depression and blood stasis, and was administered daisaikoto and tokakujokito for 1 week. After that, we switched tokakujokito to keishibukuryogan and continued treatment, but there remained a slight difference in hearing around the treble part, and it stopped at a remarkable recovery.

Tonsillectomy is an operation generally carried out in otolaryngology. Postoperatively, the pain is very strong and it is often difficult to eat for several days. This time, we experienced a case after tonsillectomy in which rikkosan was effective for pain management. The patient was a 23-year-old woman. With a diagnosis of habitual tonsillitis, we performed her tonsillectomy. Postoperative pain was strong, however, it was difficult to use both non-steroidal anti-inflammatory drug and acetaminophen due to the history of drug eruption. Pain was alleviated immediately after taking rikkosan Subsequently we managed pain by using rikkosan as needed. Following a good postoperative course, she was discharged 6 days after surgery.

Pruritus of external auditory canal is often treated with blood-enriching formulation and heat-clearing formula. Here, we report a case of intractable pruritus of external auditory canal successfully treated with tokishigyakukagoshuyushokyoto, which did not improve with blood-enriching formulation or heat-clearing formula. Our patient was a 52-year-old woman. She had itching in her left ear from the age of 45, and was treated by 5 otolaryngologists, but her symptom did not improve. I treated her with tokiinshi, shofusan, yokukansankachimpihange, unseiin, jumihaidokuto and keishibukuryogankayokuinin, but they had no effect. After reconsideration of sho, she was diagnosed as interior cold pattern, and she had tenderness in groin area. So I treated her with tokishigyakukagoshuyushokyoto, and her itching disappeared. We should consider interior cold pattern as one of the differential diagnoses of pruritus of external auditory canal.

We experienced 2 patients with clinical diagnosis of subacute necrotizing lymphadenitis who were successfully treated with shosaikoto. Case 1 is a 37-year-old woman. Left neck swelling and pain appeared from 12 days before, and temperature went up thereafter. Antibiotics were administered at another hospital, but she did not improve. There were multiple swollen lymph nodes of the left neck, and blood test showed decreased white blood cells and increased LDH. So we clinically diagnosed her as subacute necrotizing lymphadenitis. After administration of shosaikoto, fever resolved, and cervical swelling also markedly improved on the third day. On day 10, both symptom and findings disappeared. Case 2 is a 12-year-old man. Left neck swelling and pain appeared and temperature went up from 8 days before. An antibiotic was administered at another hospital, but he did not improve. There were multiple swollen lymph nodes of the left neck, and blood test showed decreased white blood cells and increased LDH. So we clinically diagnosed him as subacute necrotizing lymphadenitis, and administered shosaikoto. Then fever resolved on the third day, and cervical swelling diminished and tenderness disappeared on day 10. On day 18, both symptom and findings disappeared.

We administered Japanese Kampo medicine for seven patients with Grade 3 or more idiopathic sensorineural hearing loss who could not be administered enough amounts of steroids for some reasons. They all exhibited deficiency patterns, and which were all dual deficiency patterns of qi and yin. All patients were administered hochuekkito and hachimijiogan. Six patients were cured, and one patient was recovered.

Soshikokito has long been used to treat cough in frail patients with cold sensation in their feet, based on the Japanese traditional Kampo textbook “Iryo-Shuhou-Kiku”. In many old documents including “Wazai-Kyokuho,” where soshikokito was first described, it is suggested that airways obstructed by a large quantity of watery expectoration should be the proper indication for the use of this formula. However, in the five cases that we successfully treated, the quantity of sputum was relatively small. To determine the practical indications for this, we examined their abdominal strength and the presence or absence of “cold feet” sensation. In addition, we investigated the nature of sputum in the past clinical reports in which successful treatment using soshikokito was described. It has become clear that we can prescribe soshikokito as an antitussive regardless of the patients' physical fitness as deduced from the abdominal strength. The “cold feet” sensation was not an essential symptom and was regarded as one of the symptoms of qi counterflow. Regarding the properties of sputum, it was viscous and small in quantity. In the cases where soshikokito was effective, it was speculated that viscous sputum would result in airway obstruction, coughing, and wheezing. These conditions will be ameliorated by the antitussive and expectorant effect of this formula, which improves qi counterflow and mildly tonifies water. In the treatment of cough with respiratory distress, “sputum with high viscosity and hard to discharge” is considered to be the targeted symptom in the practical usage of soshikokito.
