Hyperlipidemia is characterized by elevated levels of blood lipids. The clinical manifestations are mainly atherosclerosis caused by the deposition of lipids in the vascular endothelium. The link between abnormal lipid metabolism and sudden hearing loss remains unclear. This article presents a case study of sudden hearing loss accompanied by familial hyperlipidemia. Pure tone audiometry indicated intermediate frequency hearing loss in one ear. Laboratory tests showed abnormal lipid metabolism, and genetic examination identified a heterozygous mutation in theAPOA5 gene. Diagnosis: Sudden hearing loss; hypercholesterolemia. The patient responded well to pharmacological treatment. This paper aims to analyze and discuss thepotential connection between abnormal lipid metabolism and sudden hearing loss.

Objective: To investigate the associations between neutrophil-to-lymphocyte ratio (NLR) and estimated glomerular filtration rate (eGFR) in patients with primary aldosteronism (PA). Methods: This study was a cross-sectional study. Consecutive patients diagnosed with PA and admitted to the Second Affiliated Hospital of Nanchang University from October 2017 to April 2022 were enrolled. General information, blood routine, renal function, and other clinical data of the patients were collected. Based on the median NLR of the enrolled patients, NLR-1·1.73 m^-2. Multiple linear regression and multivariate logistic regression models, smooth curve fitting and threshold effect exploration were used to analyze the relationship between NLR and eGFR in PA patients, and stratified analysis and interaction tests were used to evaluate potential variables that may affect the correlation between NLR and eGFR. Results: This study finally included 743 PA patients, aged (50.3±10.4) years, 42.9% (319/743) were female, and the median NLR was 2.3. After adjusting for sex, age, body mass index (BMI) and other factors, multiple linear regression analysis showed that high NLR was negatively correlated with eGFR (β=-4.9, P=0.008), and multivariate logistic regression analysis showed that high NLR was associated with low eGFR (OR=3.1, P=0.002). In the corrected smooth curve, NLR is U-shaped correlation with eGFR, and the inflection point is at NLR=3.5. When the NLR was<3.5, the eGFR decreased with the increase of NLR (corrected β=-4.7, P<0.001); When the NLR was≥3.5, the eGFR increased with the increase of NLR (corrected β=5.8, P=0.031). The results of stratified analysis showed that there was an interaction between the association of NLR and eGFR with the presence or absence of hyperlipidemia (P interaction=0.017), and the correlation between NLR and eGFR was stronger in PA patients with hyperlipidemia. Conclusion: In the PA patients, there is a U-shaped relationship between NLR and eGFR, and higher NLR is associated with lower eGFR. PA patients with elevated NLR should undergo additional screening for chronic kidney disease and receive related preventive interventions.

In the current era of effective antiretroviral therapies (ARTs), human immunodeficiency virus (HIV) infection became a chronic disorder that requires long term follow-up. Among other medical issues, these patients may develop endocrine problems, specific to HIV infection and its treatment. The purpose of this review is to give an overview of common endocrine complications associated with HIV infection, and to propose diagnostic and therapeutic strategies. HIV can affect the endocrine system at several levels. Adrenal and gonadal dysfunction, osteoporosis with increased fracture risk, dyslipidemia with increased cardiovascular risk, are some of the endocrine disorders prevalent in HIV-infected patients that may negatively influence quality of life, and increase morbidity and mortality. While ARTs have dramatically increased life expectancy in the HIV-infected population, they are not devoid of adverse effects, including endocrine dysfunction. Physicians caring for HIV-infected patients should be knowledgeable and exercise a high index of suspicion for the diagnosis of endocrine abnormalities, and in particular be aware of those that can be life threatening. Endocrine evaluation should follow the same strategies as in the general population, including prevention, early detection, and treatment.

BACKGROUND AND OBJECTIVES: We aimed to investigate the history of medical resource consumption and quality of life (QoL) in peripheral arterial disease (PAD) patients in Korea. METHODS: This was a prospective, multi-center (23 tertiary-hospitals, division of cardiology), non-interventional study. Adult patients (age ≥20 years) suffering from PAD for the last 12-month were enrolled in the study if they met with any of following; 1) ankle-brachial index (ABI) ≤0.9, 2) lower-extremity artery stenosis on computed tomography angiography ≥50%, or 3) peak-systolic-velocity-ratio (PSVR) on ultrasound ≥2.0. Medical chart review was used to assess patient characteristics/treatment patterns while the history of medical resource consumption and QoL data were collected using a patient survey. QoL was measured using EuroQoL-5-dimensions-3-level (EQ-5D-3L) score system, and the factors associated with QoL were analyzed using multiple linear regression analysis. RESULTS: This study included 1,260 patients (age: 69.8 years, male: 77.0%). The most prevalent comorbidities were hypertension (74.8%), hyperlipidemia (51.0%) and diabetes-mellitus (50.2%). The 94.1% of the patients took pharmacotherapy including aspirin (76.2%), clopidogrel (53.3%), and cilostazol (33.6%). The 12.6% of the patients were receiving smoking cessation education/pharmacotherapy. A considerable number of patients (500 patients, 40.0%) had visit history to another hospital before diagnosis/treatment at the current hospital, with visits to orthopedic units (50.4%) being the most common. At the time, 29% (or higher) of the patients were already experiencing symptoms of critical limb ischemia. Baseline EQ-5D index and EQ VAS were 0.64±0.24 and 67.49±18.29. Factors significantly associated with QoL were pharmacotherapy (B=0.05053; p=0.044) compared to no pharmacotherapy, and Fontaine stage improvement/maintain stage I (B=0.04448; p < 0.001) compared to deterioration/maintain stage II–IV. CONCLUSIONS: Increase in disease awareness for earlier diagnosis and provision of adequate pharmacotherapy is essential to reduce disease burden and improve QoL of Korean PAD patients.

There has been a sharp increase in the number of obese people worldwide thanks to modern prosperity in accordance with rapid industrialization and economic development. Recently, bariatric surgery has been applied actively to extremely obese patients (BMI>35 kg/m2) and presented as an alternative solution to provide not only weight loss but also a treatment for metabolic diseases such as diabetes mellitus, hypertension, and hyperlipidemia. Gastroesophageal reflux disease (GERD) is one of the most important diseases in morbidly obese patients, and many patients suffer from symptoms like epigastric pain, regurgitation, and dry cough. However, such symptoms are easy to be overlooked and studies on GERD are scarce in relation to bariatric surgery. In morbidly obese patients, high abdominal pressure leads to a pressure gradient between esophagus and stomach. This induces a hiatal hernia causing a greater likelihood of GERD. Many studies in regards to GERD were made after bariatric surgery (sleeve gastrectomy, Roux-en-Y gastric bypass, and gastric band), and various results have been presented. Studies should be carried out on pre-operative diagnosis of GERD, choice of operative method, and improvement of symptoms after the operation. Research is also needed upon bariatric operation in patients with uncontrolled GERD.

PURPOSE: Pulse wave velocity (PWV) is an indicator of arterial stiffness, and is considered a marker of vascular damage. However, a genome-wide association study analyzing single nucleotide polymorphisms (SNPs) associated with brachial-ankle PWV (baPWV) has not been conducted in healthy populations. We performed this study to identify SNPs associated with baPWV in healthy populations in Korea. MATERIALS AND METHODS: Genomic SNPs data for 2,407 individuals from three sites were analyzed as part of the Korean Genomic Epidemiologic Study. Without replication samples, we performed multivariable analysis as a post hoc analysis to verify the findings in site adjusted analysis. Healthy subjects aged between 40 and 70 years without self-reported history or diagnosis of hypertension, diabetes, hyperlipidemia, heart disease, cerebrovascular disease and cancer were included. We excluded subjects with a creatinine level >1.4 mg/dL (men) and 1.2 mg/dL (women). RESULTS: In the site-adjusted association analysis, significant associations (P<5×10⁻⁸) with baPWV were detected for only 5 SNPs with low minor allele frequency. In multivariable analysis adjusted by age, sex, height, body mass index, mean arterial pressure, site, smoking, alcohol, and exercise, 11 SNPs were found to be associated (P<5×10⁻⁸) with baPWV. The 5 SNPs (P<5×10⁻⁸) linked to three genes (OPCML, PRR35 and RAB40C) were common between site-adjusted analysis and multivariable analysis. However, meta-analysis of the result from three sites for the 11 SNPs showed no significant associations. CONCLUSION: Using the recent standard for genome-wide association study, we did not find any evidence of significant association signals with baPWV.

BACKGROUND: To date, numerous studies have investigated the epidemiology and clinical characteristics of male pattern hair loss (MPHL). OBJECTIVE: The purpose of this study was to evaluate a large number of long-term MPHL patients and to compare them to shorter term ones from other studies. METHODS: We retrospectively reviewed charts of patients diagnosed with MPHL during a 10-year period at the alopecia clinic at the Department of Dermatology of Myongji Hospital. RESULTS: Among 3,549 alopecia patients who had visited the hospital's alopecia clinic, 1,360 were patients demonstrating MPHL (38.3%). The most frequent age group was patients in their 20's (30.1%) followed by those in their 30's (28.2%), 40's (17.2%), 50's (9.9%), and teenagers (8.9%). There were 599 MPHL patients (44.0%) with a paternal familial predisposition, 182 (13.4%) with a maternal familial predisposition, and 118 (8.7%) with familial predisposition on maternal and paternal sides. MPHL was classified based on the Norwood-Hamilton classification: type 2 (20.0%), type 3v (19.4%), and type 3a (16.3%) were the most frequent. Abnormalities in total serum cholesterol were found in 15.1% patients and triglycerides in 36.1% of patients. The most common comorbidity was seborrheic dermatitis, followed by hypertension, hyperlipidemia, diabetes mellitus, and gastrointestinal diseases. CONCLUSION: This study demonstrated that the period of MPHL diagnosis and treatment becomes earlier in age and milder regarding MPHL type, which may be due to early puberty in teenagers.

BACKGROUND: The prevalence and clinical characteristics of psoriatic arthritis (PsA) in patients with psoriasis are not well described in Asian populations, including Koreans. OBJECTIVE: The purpose of this study was to investigate the prevalence of PsA by using the classification of psoriatic arthritis (CASPAR) criteria on the basis of physical examination only, as well as its correlation with psoriasis severity and other medical conditions including nail psoriasis. METHODS: A single-center, cross-sectional observational cohort study was conducted, and the included patients were evaluated for PsA according to the CASPAR criteria. The psoriasis area severity index (PASI) and the nail psoriasis severity index (NAPSI) were calculated. RESULTS: The prevalence of PsA in patients with psoriasis in Korea was 13.5%. When performing logistic regression, hyperlipidemia and localized pustular psoriasis were found to be significant predictors of PsA. The PASI score was significantly higher in PsA patients than in those with psoriasis alone (p=0.014). Psoriatic nail involvement was found in 85.5% of the study population, and all PsA patients had nail psoriasis. The mean NAPSI score was higher in patients with PsA; however, the difference was not statistically significant. CONCLUSION: There was a close relation between psoriasis severity and PsA, although nail psoriasis severity was not related to PsA status. Dermatologists can diagnose PsA from current physical findings by using the CASPAR criteria. To validate the CASPAR criteria for PsA diagnosis, the definition of nail psoriasis clinical types and severity in the CASPAR criteria should be reviewed again.
