Objective Chronic thromboembolic pulmonary hypertension (CTEPH) is a form of pulmonary hypertension caused by persistent thromboemboli of the pulmonary arteries, and one of its etiological factors may be inflammation. Sleep disordered breathing (SDB) is reportedly an important complication of pulmonary hypertension. However, the association between SDB and inflammation in CTEPH has been undefined. ⋯ The circulating tumor necrosis factor-alpha (TNF-α) level was also high in the CTEPH group, and a multivariate analysis showed that the nocturnal mean SpO2 was the most important predictive factor for a high TNF-α level. Conclusion We showed that CTEPH patients had high serum TNF-α levels and that the nocturnal mean SpO2 was a predictive factor for serum TNF-α levels. Further investigations focused on nocturnal hypoxemia and the TNF-α level may provide novel insight into the etiology and new therapeutic strategies for CTEPH.

Successful Introduction of Peritoneal Dialysis in an End-stage Renal Failure Patient with Idiopathic Aplastic Anemia.
A 45-year-old man with idiopathic aplastic anemia required renal replacement therapy (RRT) due to end-stage renal disease (ESRD). We succeeded in inserting the peritoneal dialysis (PD) catheter under cover of frequent red blood cell and platelet infusions because of severe pancytopenia. During the one-year period after starting PD using an ultraviolet-ray sterilization device, he developed severe leukopenia but no PD-related peritonitis or exit site/tunnel infection until he died of pneumonia. This case suggests that PD might be a suitable choice as RRT in ESRD patients with aplastic anemia, even in those with severe pancytopenia.

A 65-year-old woman presented to a hospital with complaints of dyspnea and lumbar pain. Chest computed tomography (CT) showed left pleural effusion. Thoracentesis showed pleural effusion with elevated levels of amylase. ⋯ Conservative management was performed. However, occlusion of the pancreatic fistula failed. Subsequently, she underwent pancreatic body tail spleen merger resection, and the pleural effusion disappeared.

Objective Patient-reported outcomes (PROs) are important measures of the quality of life (QOL) and symptoms in patients with hepatitis C virus (HCV). We evaluated the PROs at the beginning of direct-acting antiviral (DAA) treatment and three years later. A low QOL in patients with chronic liver disease suggested a low muscle mass. ⋯ The sleep quality, sleep latency, fatigue, and abdominal fullness were related to dGHN. Conclusion The QOL is related to sleep disturbance and several other symptoms. Furthermore, in patients with an increased muscle volume after DAA treatment, increased muscle mass is associated with an improvement in the QOL.

Case Reports
A Healthy Family of Familial Hypobetalipoproteinemia Caused by a Protein-truncating Variant in the PCSK9 Gene.
We present the first case of a Japanese patient with familial hypobetalipoproteinemia (FHBL) caused by a protein-truncating variant in the proprotein convertase subtilisin/kexin type 9 (PCSK9) gene. A 34-year-old woman was referred to our hospital due to her low low-density lipoprotein (LDL)-cholesterolemia (34 mg/dL). She did not have any secondary causes of hypobetalipoproteinemia. ⋯ We identified a protein-truncating variant in the PCSK9 gene (c.1090_1091del/p. Pro364ArgfsTer62) among them. None of them exhibited atherosclerotic cardiovascular diseases nor any other complications associated with low LDL cholesterol, including fatty liver, neurocognitive disorders, or cerebral hemorrhaging.
