RESUMEN
Background: Tirzepatide-a dual glucose-dependent insulinotropic peptide and glucagon-like peptide-1 receptor agonist-is used to treat type 2 diabetes. However, the efficacy and safety of tirzepatide in patients undergoing hemodialysis remain unclear. Methods: We conducted a single-center retrospective study of patients with type 2 diabetes undergoing hemodialysis who were transitioned from dulaglutide to tirzepatide. We continuously monitored glucose levels in patients undergoing hemodialysis before and after switching from dulaglutide to tirzepatide. Results: Fourteen patients (mean age: 61.9 ± 9.9 years, male: female = 11:3) were included in this study. After switching to tirzepatide, time in range increased to 50.8% from 42.7% (p = 0.02), time above range decreased to 37.8% from 48.4% (p = 0.02), and mean glucose levels decreased to 137.4 mg/dL from 156.6 mg/dL (p = 0.006). In contrast, there was no significant difference in time below range before and after tirzepatide administration (11.3% and 8.9%) (p = 0.75). Three patients experienced dyspepsia (21.4%), and one patient experienced nausea (7.1%); however, no critical adverse events were reported. Conclusion: Transitioning from dulaglutide to tirzepatide improved glycemic control without increasing hypoglycemia in patients undergoing hemodialysis for type 2 diabetes.
RESUMEN
BACKGROUND AND OBJECTIVE: The identification of factors associated with long-term prognosis after community-onset pneumonia in elderly patients should be considered when initiating advance care planning (ACP). We aimed to identify these factors and develop a prediction score model. METHODS: Patients aged 65 years and older, who were hospitalized for pneumonia at nine collaborating institutions, were included. The prognosis of patients 180 days after the completion of antimicrobial treatment for pneumonia was prospectively collected. RESULTS: The total number of analysable cases was 399, excluding 7 outliers and 42 cases with missing data or unknown prognosis. These cases were randomly divided in an 8:2 ratio for score development and testing. The median age was 82 years, and there were 68 (17%) deaths. A multivariate analysis showed that significant factors were performance status (PS) ≥2 (Odds ratio [OR], 11.78), hypoalbuminemia ≤2.5 g/dL (OR, 5.28) and dementia (OR, 3.15), while age and detection of antimicrobial-resistant bacteria were not associated with prognosis. A scoring model was then developed with PS ≥2, Alb ≤2.5, and dementia providing scores of 2, 1 and 1 each, respectively, for a total of 4. The area under the curve was 0.8504, and the sensitivity and specificity were 94.6% and 61.7% at the cutoff of 2, respectively. In the test cases, the sensitivity and specificity were 91.7% and 63.1%, respectively, at a cutoff value of 2. CONCLUSION: Patients meeting this score should be considered near the end of life, and the initiation of ACP practices should be considered.

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder that causes abnormal blood vessel formation and bleeding. We herein report a 61-year-old woman with aggravated HHT symptoms after hemodialysis initiation. She was diagnosed with HHT based on her recurrent bleeding, abnormal blood vessel formation, and family history. Despite bleeding complications, the patient required anticoagulants and antiplatelet agents to treat cardiovascular complications. Eventually, the patient died of extensive cerebral hemorrhaging. Our experience suggests that special attention should be paid to bleeding complications in high-risk patients.
RESUMEN
INTRODUCTION: Sequential vaccination with the 13-valent pneumococcal protein conjugate vaccine (PCV13) and 23-valent pneumococcal polysaccharide vaccine (PPSV23) is recommended for patients undergoing hemodialysis; however, evidence for the efficacy of these pneumococcal vaccines for patients undergoing hemodialysis is limited to a single dose. We aimed to evaluate the prognosis of patients undergoing hemodialysis who received vaccination with PPSV23 alone versus sequential vaccination with PCV13 and PPSV23. METHODS: Patients undergoing hemodialysis who were vaccinated with PPSV23 alone (PPSV23 group) or PCV13 followed by PPSV23 (PCV13+PPSV23 group) between 2014 and 2016 were included; the observation period was three years from the first injection. Patients who underwent hemodialysis between 2011 and 2012 were included as controls. After propensity score matching using age, sex, dialysis vintage, diabetes history, pneumonia history, and serum albumin and creatinine levels, survival analysis was performed. RESULTS: The study included 89, 71, and 319 patients in the PPSV23, PCV13+PPSV23, and control groups, respectively. After propensity score matching, the PPSV23 and control group 1 (79 patients each) and the PCV13+PPSV23 and control group 2 (61 patients each) were compared. Significant differences were observed in the survival rate between the PPSV23 group and control group 1 (p = 0.005) but not between the PCV13+PPSV23 group and control group 2. Pneumonia-related mortality in the two vaccinated groups did not differ significantly during the observation period. CONCLUSIONS: Patients who received PPSV23 had a favorable prognosis; however, no positive effect was demonstrated in the PCV13+PPSV23 group.
RESUMEN
AIM: This study aimed to verify the impact of low body mass index (BMI) on mortality in nursing home residents undergoing hemodialysis and to clarify other associated mortality risk factors. METHODS: This retrospective study included patients admitted to a nursing home affiliated with Nagasaki Renal Center between April 2014 and March 2022. Medical data were collected on admission, and participants were divided into low and high BMI groups according to their median BMI values. The patients were followed up until March 2023. The association between survival and patient history was also analyzed. RESULTS: Of the 106 patients (average age, 81.3 ± 7.9 years; male, 36.8%; median dialysis vintage, 32.5 [interquartile range (IQR), 13.8-79.3] months), 52 and 54 were classified into the low (median < 18.4 kg/m2 ) and high (≥18.4 kg/m2 ) BMI groups, respectively. Multivariable Cox proportional hazards analysis indicated that BMI (hazard ratio, 0.87; 95% confidence interval [CI]: 0.82-0.94; P < 0.001) was closely associated with survival. Multivariable logistic regression revealed that dementia was associated with low BMI (odds ratio: 2.89, 95% CI: 1.07-7.83, P = 0.03). CONCLUSIONS: Low BMI was an important factor contributing to poor patient survival. Dementia was associated with low BMI. Therefore, the management of both nutrition and dementia is essential for nursing home residents undergoing hemodialysis. Geriatr Gerontol Int 2023; 23: 660-664.

BACKGROUND: Hyperkalemia and hypokalemia are associated with mortality in patients undergoing hemodialysis. However, there are few reports on the association between potassium level fluctuations and mortality. We retrospectively investigated the association between serum potassium level variability and mortality in patients undergoing hemodialysis. METHODS: This study was conducted at a single center. Variability in serum potassium levels was evaluated using the standard deviation of potassium level from July 2011 to June 2012, and its association with prognosis was examined by following up the patients for 5 years. Serum potassium variability was assessed as the coefficient of variation, and the statistical analysis was performed after log transformation. RESULTS: Among 302 patients (mean age 64.9 ± 13.3; 57.9% male; and median dialysis vintage 70.5 months [interquartile range, IQR 34-138.3]), 135 died during the observation period (median observation period 5.0 years [2.3-5.0]). Although the mean potassium level was not associated with prognosis, serum potassium level variability was associated with prognosis, even after adjustments for confounding factors such as age and dialysis time (hazard ratio: 6.93, 95% confidence interval [Cl] 1.98-25.00, p = 0.001). After the adjustments, the coefficient of variation of potassium level in the highest tertile (T3) showed a higher relative risk for prognosis than that in T1 (relative risk: 1.98, 95% CI 1.19-3.29, p = 0.01). CONCLUSIONS: Variability in serum potassium levels was associated with mortality in patients undergoing hemodialysis. Careful monitoring of potassium levels and their fluctuations is necessary for this patient population.

Anorexia is a common symptom in older patients undergoing hemodialysis (HD) and has become a serious problem in dialysis facilities with the aging of patients. Polypharmacy, defined as the prescription of several medications, is known to cause drug-induced anorexia. Although polypharmacy is also common in older patients undergoing HD, only a few studies have examined the association between anorexia and polypharmacy. This study used the Simplified Nutritional Appetite Questionnaire for Japanese Elderly (SNAQ-JE) to evaluate patients' appetite, and examined its association with medications. This cross-sectional study included 233 patients (aged ≥65 years) who underwent HD in October 2021. Among the 233 patients (median age, 73.0 [interquartile range (IQR), 69.0-80.5] years; men, 57.3%; median dialysis vintage, 62.0 [IQR, 30.0-122.0] months), 116 and 117 were classified into the poor (SNAQ-JE total score ≤14) and good (>14) appetite groups, respectively. Although the total number of medications prescribed was not significantly different between the two groups (p = 0.12), the number of antihypertensive drugs was significantly lower (p = 0.03), and that of sleeping medications was significantly higher (p = 0.002) in the poor appetite group. Multivariable logistic regression analysis showed that the number of sleeping medications was associated with poor appetite (odds ratio, 2.08; 95% confidence interval, 1.32-3.27; p < 0.001). The findings suggest that the number of sleeping medications is an important contributing factor to poor appetite in older patients undergoing HD. A proper and regular review of prescriptions may be necessary to improve anorexia.

Older hospitalized patients undergoing hemodialysis are increasingly experiencing malnutrition caused by dysphagia. However, only a few studies have focused on this problem. We used the Kuchikara Taberu Balance Chart (KTBC) to evaluate the patients' feeding status and examined its association with their nutritional status and prognosis. This study included elderly patients undergoing hemodialysis who were hospitalized at Nagasaki Renal Center for > 3 days between June 2021 and February 2022. In total, 82 inpatients were included [mean age, 73.4 ± 10.0 years; men, 57.3%; median dialysis vintage, 79.0 months (interquartile range, 37.3-164.8)]. We classified patients with lower than the median KTBC score (57 points) as being at risk for dysphagia; 37 patients (45.1%) were at risk for dysphagia. Spearman's rank correlation coefficient (ρ) elucidated that the KTBC total score was significantly associated with each nutritional indicator [serum albumin level (ρ = 0.505, p < 0.001); geriatric nutritional risk index (ρ = 0.600, p < 0.001); and nutritional risk index (ρ = -0.566, p < 0.001)]. The KTBC score was also closely associated with the body mass index (ρ = 0.228, p = 0.04). Patients with a lower KTBC score showed poor prognosis (log-rank test: p = 0.001), and age- and sex-adjusted Cox proportional analysis showed that the KTBC score was associated with life prognosis (hazard ratio, 0.90; 95% confidential interval, 0.86-0.94; p < 0.001). Therefore, we concluded that the patients at risk of dysphagia, identified using the KTBC score, were malnourished and had a poor prognosis. Hence, the evaluation of dysphagia using the KTBC is encouraged to prevent malnutrition in vulnerable older patients undergoing hemodialysis.

AIM: This study aimed to elucidate the 5-year changes in the cognitive function of elderly patients undergoing hemodialysis and its association with survival and related factors. METHODS: Cognitive function in patients aged ≥65 years undergoing hemodialysis at the Nagasaki Renal Center was assessed using the Mini-Mental State Examination (MMSE) in 2016. Patients were subsequently classified into normal, mild cognitive impairment (MCI) and suspected dementia groups according to their scores; MMSE was conducted at 30 and 60 months thereafter. The patients were followed until 2021. The association between survival and patient backgrounds was analyzed. RESULTS: Of the 181 patients, 168 completed follow-up and were classified into normal (n = 71, 42.3%), MCI (n = 44, 26.1%), and suspected dementia (n = 53, 31.5%) groups. Multivariable logistic regression analysis showed that age, female sex, and geriatric nutritional risk index were associated with MMSE scores <24. The 5-year survival rates were 60.6%, 40.9%, and 22.6% in the normal, MCI and suspected dementia groups, respectively. With some exceptions, MMSE results tended to decline during the observation period. A multivariate Cox proportional hazards model showed that age (hazard ratio [HR], 1.04; P = 0.007), dialysis vintage (HR, 0.96; P = 0.04), male sex (HR, 1.77; P = 0.02), geriatric nutritional risk index (HR, 0.94; P < 0.001) and MMSE score (HR, 0.96; P = 0.01) were independent risk factors for patient survival. CONCLUSIONS: Cognitive impairment in patients undergoing hemodialysis was associated with age and nutritional status. Patients with cognitive impairment had a poor prognosis.

INTRODUCTION: Diabetes mellitus is one of the most important risk factors for lower-limb amputation in patients undergoing hemodialysis. However, the influence of diabetes mellitus on survival after lower-limb amputation is unknown. METHODS: Patients who underwent lower-limb amputation since 1996 (amputation group) and those who underwent hemodialysis during 2011-2012 (control group) were included and were followed up until July 2022. RESULTS: There were 70 patients (age: 66.3 ± 8.2 years, 80% male, 77% diabetic) in the amputation group and 328 (age: 67.5 ± 13.5 years, 56% male, 33% diabetic) in the control group. The amputation group showed a poorer prognosis than the control group (hazard ratio [HR]: 2.41, p < 0.001). In the control group, patients with diabetes exhibited poorer survival than those without diabetes (HR: 1.86, p < 0.001). In the amputation group, patients with diabetes exhibited improved survival (HR: 0.47, p = 0.02). CONCLUSION: Patients undergoing hemodialysis who underwent lower-limb amputation exhibited a poor prognosis, irrespective of diabetes status.

INTRODUCTION: Withdrawal from maintenance hemodialysis is unavoidable in some patients due to their poor general condition; however, their survival days vary depending on their health status. The factors associated with life prognosis in the terminal phase in patients undergoing hemodialysis remain unclear. METHODS: Patients who died after withdrawal from hemodialysis between 2011 and 2021 at Nagasaki Renal Center were included. Patient background data were collected, and the association between the patients' clinical features and survival duration was analyzed. RESULTS: The withdrawal group included 174 patients (79.8 ± 10.8 years old; 50.6% male; median dialysis vintage, 3.6 years). The most common reason for withdrawal (95%) was that hemodialysis was more harmful than beneficial because of the patient's poor general condition. The median time from withdrawal to death was 4 days (interquartile range, 3-10 days). Multivariable Cox proportional regression analysis showed that oral nutrition (hazard ratio (HR), 1.98; 95% confidence interval (CI), 1.12-3.50; P = 0.03), hypoxemia (HR, 2.32; 95% CI, 1.55-3.47; P < 0.01), ventilator use (HR, 0.26; 95% CI, 0.11-0.58; P < 0.01), and pleural effusion (HR, 1.54; CI, 1.01-2.37; P = 0.04) were associated with increased survival duration. In contrast, antibiotics and vasopressor administration were not associated with the survival duration. CONCLUSION: In this study, we explored the parameters affecting the survival of patients who withdrew from hemodialysis. Physicians could use our results to establish more accurate predictions, which may help the patient and their family to emotionally accept and implement the desired care plan.

Patients undergoing hemodialysis are known to exhibit low humoral responses to vaccines against severe acute respiratory syndrome coronavirus 2. In this study, we aimed to elucidate the humoral response to the third dose of BNT162b2 (Pfizer) in patients undergoing hemodialysis. We included 279 patients undergoing hemodialysis (69 ± 11 years, 65% male, median dialysis vintage: 69 months) and 189 healthcare workers (45 ± 13 years, 30% male) who received the third dose of BNT162b2. Anti-spike immunoglobulin G (anti-S IgG) antibody levels were measured 3−4.5 months after the second dose and 3 weeks after the third dose and were compared. Despite a significant difference in anti-S IgG antibody levels after the second dose between the two groups (patients: median 215 U/mL and healthcare workers: median 589 U/mL; p < 0.001), no significant difference in anti-S IgG antibody levels after the third dose was observed (patients: median 19,000 U/mL, healthcare workers: median 21,000 U/mL). Except for dialysis vintage (ρ = 0.209, p < 0.001), no other factors correlated with anti-S IgG antibody levels after the third vaccine dose in patients undergoing hemodialysis. Therefore, a favorable response to the third dose of BNT162b2 was observed in patients undergoing hemodialysis, irrespective of their backgrounds.
RESUMEN
Despite evident lifestyle changes due to measures against the coronavirus disease 2019 (COVID-19) outbreak, few reports focus on the effects of eating-behavior changes on the nutritional status of elderly patients undergoing hemodialysis (HD). Thus, we examined dry-weight reduction, the simplest indicator of malnutrition among patients undergoing dialysis, and its association with the discontinuation of cafeteria services at a dialysis facility as per COVID-19 measures. This retrospective study included elderly patients (aged ≥ 65 years) undergoing HD at the Nagasaki Renal Center between December 2020 and October 2021. We collected nutrition-related data and patient characteristics and evaluated the association between the service discontinuation and dry-weight reduction 10 months after the discontinuation using multivariable logistic regression. This study included 204 patients, 79 of which were cafeteria users. During the observation period, cafeteria users showed significant dry-weight reduction; however, this was not observed among non-users. Multivariable logistic regression analysis indicated a close association between dry-weight reduction and the service discontinuation. That is, the dietary services cancelation caused dry-weight reduction in patients who relied on the cafeteria. As elderly patients undergoing HD are vulnerable to changes in their eating environment, alternative nutritional management methods need to be considered.

Background: Patients on hemodialysis (HD) face a high mortality risk from coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and they are therefore prioritized for vaccination. However, the efficacy of vaccination in this vulnerable population has not been confirmed. Although age is negatively correlated with serum immunoglobulin (Ig) levels, humoral responses to vaccination in elderly patients undergoing HD have not been investigated. To address this issue, we evaluated the anti-SARS-CoV-2 spike protein antibodies in nursing home residents on HD after BNT162b2 vaccine administration. Methods: Patients on HD from a nursing home and care workers (controls) receiving two doses of the BNT162b2 vaccine between April and May 2021 were enrolled in this study. Those with a prior history of COVID-19 were excluded. Anti-spike protein antibodies were measured with the Elecsys (Roche) immunoassay system. Results: The study included 26 nursing home residents (41% male; median age, 86 years) and 184 care workers (28% male; median age, 45 years). The median HD vintage was 51 months. After two doses of BNT162b2, 73% of the nursing home residents and 99.5% of the control group developed sufficient anti-spike protein antibodies (> 29 U/mL) to neutralize SARS-CoV-2. Three weeks after the second dose, median IgG titers of the residents and care workers were 83 [interquartile range (IQR) 17-511] and 1365 (IQR 847-2245) U/mL, respectively (p < 0.001). Conclusions: The humoral response to BNT162b2 among elderly HD patients was relatively low; therefore, the optimal vaccination strategy for this population should be studied further to avoid COVID-19 outbreaks in healthcare facilities.

RESUMEN
BACKGROUND: Hemodialysis (HD) is a common renal replacement therapy for patients with renal failure. Cardiovascular and cerebrovascular diseases are known to shorten survival periods and worsen the quality of life of HD patients. Atherosclerosis is a major cause of vascular diseases, and various factors such as abnormality of lipid metabolism and increased macrophage activity, oxidative stress, and endothelial dysfunction are associated with its pathogenesis and progression. Further, endothelial stem cells (ESCs) have been reported to play important roles in endothelial functions. Royal jelly (RJ) affects atherosclerosis- and endothelial function-related factors. The main aim of this trial is to investigate whether oral intake of RJ can maintain endothelial function in HD patients. In addition, the effects of RJ intake on atherosclerosis, ESC count, inflammation, and oxidative stress will be analyzed. METHODS: This will be a multicenter, prospective, double-blind, randomized controlled trial. We will enroll 270 participants at Nagasaki Jin Hospital, Shinzato Clinic Urakami, and Maeda Clinic, Japan. The participants will be randomized into RJ and placebo groups. The trial will be conducted according to the principles of the Declaration of Helsinki, and all participants will be required to provide written informed consent. The RJ group will be treated with 3600 mg/day of RJ for 24 months, and the placebo group will be treated with starch for 24 months. The primary endpoint will be the change in flow-mediated dilation (FMD), a parameter of endothelium function, from the time before treatment initiation to 24 months after treatment initiation. The secondary and other endpoints will be changes in FMD; ESC count; serum levels of vascular endothelial cell growth factor, macrophage colony-stimulating factor, 8-hydroxydeoxyguanosine, and malondialdehyde; the incidence of cardiovascular diseases, cerebrovascular diseases, and stenosis of blood access; and safety. DISCUSSION: This trial will clarify whether oral intake of RJ can maintain endothelial function and suppress the progression of atherosclerosis in HD patients. In addition, it will clarify the effects of RJ on ESCs, oxidative stress, and angiogenic activity in blood samples. TRIAL REGISTRATION: The Japan Registry of Clinical Trials jRCTs071200031 .

Although polypharmacy is common among patients on hemodialysis (HD), its association with prognosis remains unclear. This study aimed to elucidate the association between the number of prescribed medicines and all-cause mortality in patients on HD, accounting for essential medicines (i.e., antihypertensives, antidiabetic medicines, and statins) and non-essential medicines. We evaluated 339 patients who underwent maintenance HD at Nagasaki Renal Center between July 2011 and June 2012 and followed up until June 2021. After adjusting for patient characteristics, the number of regularly prescribed medicines (10.0 ± 4.0) was not correlated with prognosis (hazard ratio [HR]: 1.01, 95% confidence interval [CI] 0.97-1.05, p = 0.60). However, the number of non-essential medicines (7.9 ± 3.6) was correlated with prognosis (HR: 1.06, 95% CI 1.01-1.10, p = 0.009). Adjusting for patient characteristics, patients who were prescribed more than 10 non-essential medicines were found to have a significantly higher probability of mortality than those prescribed less than five non-essential medicines, with a relative risk of 2.01 (p = 0.004). In conclusion, polypharmacy of non-essential medicines increases the risk of all-cause mortality in patients on HD. As such, prescribing essential medicines should be prioritized, and the clinical relevance of each medicine should be reviewed by physicians and pharmacists.

BACKGROUND: Although muscle mass loss and pneumonia are common and crucial issues in hemodialysis (HD) patients, few reports have focused on their association, which remains unclear. This study assessed the association between skeletal muscle mass and the incidence of pneumonia in HD patients using the psoas muscle index (PMI). METHODS: This retrospective study included 330 patients on HD who were treated at a single center between July 2011 and June 2012. The observation period was between July 2011 and June 2021. Demographic, clinical, and HD data were collected, and the associations between PMI and hospitalization due to bacterial pneumonia were evaluated using Cox proportional hazards models adjusted for patients' background data. Additionally, the correlation between patient characteristics and PMI was evaluated using multivariable linear regression. RESULTS: Among 330 patients (mean age, 67.3 ± 13.3; 56.7% male; median dialysis vintage 58 months, (interquartile range [IQR] 23-124), 79 were hospitalized for pneumonia during the observation period (median observation period was 4.5 years [IQR 2.0-9.1]). The multivariable Cox proportional analysis, which was adjusted for age, sex, dialysis vintage, diabetes mellitus, and stroke history and considered death as a competing risk, indicated that decreased PMI/(standard deviation) was closely associated with the development of pneumonia (hazard ratio: 0.67, 95% confidence interval: 0.47-0.95, p = 0.03). CONCLUSIONS: Skeletal muscle mass was associated with the development of pneumonia in patients on HD and could be a useful marker for the risk of pneumonia.

Muscle mass loss and worsening physical function are crucial issues in patients receiving hemodialysis (HD). However, few studies have investigated the association between temporal changes in muscle mass and physical function in a large number of HD patients. We examined 286 patients receiving HD (males, 58%; age, 66.8 ± 13.0 years) at a single center, and calculated the percent changes in psoas muscle mass index (%PMI) using computed tomography over two screenings, once per year (July 2011-June 2013). Physical function was evaluated using the Eastern Cooperative Oncology Group Performance Status (ECOG-PS) (range 0-4). The observation period was from July 2012 to June 2021. The median %PMI was -9.5%, and those with the lowest quartile of %PMI (< -20.5%) showed a significantly poor prognosis compared with other patients (p < 0.001). Multivariable logistic regression analysis revealed that these patients tended to have decreased physical function (ECOG-PS 2-4) [odds ratio (OR): 2.46, p < 0.001] and albumin levels (OR: 0.22, p = 0.007). Multiple-factor-adjusted Cox regression analyses showed that %PMI (hazard ratio: 0.99, p = 0.004) and each ECOG-PS stage (1-4 vs. 0) (p < 0.01) were associated with mortality. Augmenting physical activities in daily life and serum albumin levels should be considered to maintain muscle mass and improve the prognosis of patients receiving HD.

BACKGROUND Calcification in arteries is sometimes observed in patients undergoing hemodialysis; however, ectopic calcification in other organs is uncommon. In particular, diffuse liver calcification is very rare. We report a case of rapidly developing diffuse liver calcification in a patient undergoing hemodialysis. CASE REPORT An 82-year-old woman started hemodialysis because of diabetic nephropathy, and her renal function worsened due to acute coronary syndrome. Percutaneous coronary intervention was conducted, and she was referred to our hospital. However, she subsequently contracted various infections, including a urinary tract infection and pneumonia. On day 43 of hospitalization, she developed septic shock and liver dysfunction due to catheter-induced infection. Although she did not have any medical history of liver disease, hypoperfusion of the liver resulted in liver dysfunction, and a computed tomography scan conducted 3 months later showed diffuse calcification in her liver. Despite recovering from septic shock, she ultimately died of multiple organ failure 21 months after admission to our hospital. CONCLUSIONS Diffuse liver calcification is extremely rare; however, it can be observed in patients undergoing hemodialysis who experience liver hypoperfusion. The precise mechanisms underlying this disorder remain unknown, but a critically ill status and specific characteristics of hemodialysis patients may play important roles in liver calcification.
