  • Vitamin D is an essential component of bone and mineral metabolism; its deficiency causes growth retardation and skeletal deformities in children and osteomalacia and osteoporosis in adults. Hypovitaminosis D (vitamin D insufficiency or deficiency) is observed not only in adults but also in infants, children, and adolescents. Previous studies suggest that sufficient serum vitamin D levels should be maintained in order to enhance normal calcification of the growth plate and bone mineralization. Moreover, emerging evidence supports an association between 25-hydroxyvitamin D (25[OH]D) levels and immune function, respiratory diseases, obesity, metabolic syndrome, insulin resistance, infection, allergy, cancers, and cardiovascular diseases in pediatric and adolescent populations. The risk factors for vitamin D insufficiency or deficiency in the pediatric population are season (winter), insufficient time spent outdoors, ethnicity (non-white), older age, more advanced stage of puberty, obesity, low milk consumption, low socioeconomic status, and female gender. It is recommended that all infants, children, and adolescents have a minimum daily intake of 400 IU ($10{\mu}g$) of vitamin D. Since the vitamin D status of the newborn is highly related to maternal vitamin D levels, optimal vitamin D levels in the mother during pregnancy should be maintained. In conclusion, given the important role of vitamin D in childhood health, more time spent in outdoor activity (for sunlight exposure) and vitamin D supplementation may be necessary for optimal health in infants, children, and adolescents.

  • Objectives : We examined quality of life, psychosocial adjustments to illness, changes in sexual functioning, and prevalence of psychiatric disorders in AIDS patients compared to patients with chronic hepatitis B virus infection (CHB). Methods : Thirty-one men with AIDS and 50 men with CHB were enrolled. The Short-Form 12-Item Health Survey (SF-12), the Psychosocial Adjustment to Illness Scale (PAIS), and the Changes in Sexual Functioning Questionnaire short form (CSFQ-14) were administered. Results on these assessments were compared between the 31 AIDS patients and 50 CHB patients. The Structured Clinical Interview for DSMIV (SCID) was administered to determine the psychiatric diagnosis only for the AIDS patients. Results : The Physical Component Summary score (PCS) was lower in AIDS patients than in CHB patients (p<0.001). In the section examining sexual relationships, AIDS patients exhibited a lower level of adjustment (p<0.05) and had more changes in sexual function (p<0.05) than did CHB patients. Administration of the SCID to AIDS patients indicated that the lifetime prevalence of any psychiatric disorder was 56.7% ; 43.3% for mood disorders, 33.3% for alcohol use disorders, 26.7% for anxiety disorders, and 20% for adjustment disorder. Patients who had experienced any psychiatric disorder had more severe psychosocial distress (p=0.004) and evidenced a lower level of overall psychosocial adjustment (p=0.030) than patients who had not. Conclusion : We showed that AIDS patients have a high prevalence of psychiatric disorders, and that AIDS patients with psychiatric disorders were particularly low in levels of psychosocial adjustment. Thus, careful attention should be given to psychiatric aspects of AIDS patients emphasizing the early diagnosis and treatment of psychiatric disorders.

  • Background/Aims: Vitamin D modulates innate and adaptive immune responses, and vitamin D deficiency is associated with increased mortality in hospitalized patients with pneumonia. We evaluated the prevalence of vitamin D deficiency in Korean patients with acute respiratory distress syndrome (ARDS) and its effect on the clinical outcomes of ARDS. Methods: We retrospectively analyzed the data of 108 patients who had a measured serum level of 25-hydroxy vitamin D3 ($25(OH)D_3$) at the time of diagnosis with ARDS. The clinical outcomes were evaluated based on $25(OH)D_3$ levels of 20 ng/mL and stratified by quartiles of $25(OH)D_3$ levels. Results: The mean age of patients was 59.4 years old; 77 (71.3%) were male. Vitamin D deficiency was found in 103 patients (95.4%). The mean $25(OH)D_3$ level was $8.3{\pm}7.0ng/mL$. Neither in-hospital mortality (40.0% vs. 68.0%) nor 6-month mortality (40.0% vs. 71.8%) significantly differed between groups. There were no significant differences in $25(OH)D_3$ level between survivors ($8.1{\pm}7.6ng/mL$) and non-survivors ($8.5{\pm}6.8ng/mL$, p = 0.765). There were no trends toward a difference in mortality among quartiles of $25(OH)D_3$ levels. However, $25(OH)D_3$ levels were inversely related with length of hospital stay and intensive care unit stay among in-hospital survivors. Conclusions: Vitamin D deficiency was prevalent in Korean patients with ARDS. However, levels of vitamin D were not associated with mortality. A large, prospective study is needed to evaluate the effects of vitamin D deficiency on clinical outcomes of ARDS.

  • Human immunodeficiency virus (HIV) is the causative agent of acquired immune deficiency syndrome (AIDS). Anti-HIV agents targeting various steps in HIV life cycle have been developed; however, so far, no effective drugs have been found. We show here that a peptide isolated from Spirulina maxima (SM-peptide) inhibits HIV-1 infection in a human T cell line MT4. SM-peptide inhibited $HIV-1_{IIIB}$-induced cell lysis with a half-maximal inhibitory concentration ($IC_{50}$) of 0.691 mM, while its 50 % cytotoxic concentration ($CC_{50}$) was greater than 1.457 mM. Furthermore, the SM-peptide inhibited the HIV-1 reverse transcriptase activity and p24 antigen production. This suggests that SM-peptide is a novel candidate peptide, which may be developed as a therapeutic agent for acquired immunodeficiency syndrome patients.

  • CHARGE syndrome (coloboma, heart defects, atresia choanae, retarded growth and development, genital hypoplasia, and ear abnormalities) is characterized by multiple malformations and is diagnosed using distinct consensus criteria. Mutations in the gene encoding chromodomain helicase DNA-binding protein 7 (CHD7) are the major cause of CHARGE syndrome. Clinical features of CHARGE syndrome considerably overlap those of 22q11.2 deletion syndrome. Of these features, immunodeficiency and hypocalcemia are frequently reported in patients with 22q11.2 deletion syndrome but are rarely reported in patients with CHARGE syndrome. In this report, we have described the case of a patient with typical phenotypes of 22q11.2 deletion syndrome but without the proven chromosome microdeletion. Mutation analysis of CHD7 identified a pathogenic mutation (c.2238+1G>A) in this patient. To our knowledge, this is the first case of CHARGE syndrome with immunodeficiency and hypocalcemia in Korea. Our observations suggest that mutation analysis of CHD7 should be performed for patients showing the typical phenotypes of 22q11.2 deletion syndrome but lacking the proven chromosome microdeletion.

  • Background: Korean Red Ginseng (KRG) is widely used for strengthening the immune system and fighting fatigue, especially in people with deficiency syndrome. However, there is concern that the long-term application or a high dose of KRG can cause "fireness" (上火 in Chinese) because of its "dryness" (燥性 in Chinese). The aim of this study was to assess the safety and efficacy of a 4-week treatment with KRG in participants with deficiency syndrome. Methods: This was a 4-week, randomized, double-blind, placebo-controlled clinical trial. A total of 180 Chinese participants were randomly allocated to three groups: placebo control group, participants were given a placebo, 3.6 g/d; KRG 1.8 g and 3.6 g groups. The primary outcomes were the changes in fireness and safety evaluation (adverse events, laboratory tests, and electrocardiogram). The secondary outcomes were the efficacy of KRG on fatigue, which include the following: traditional Chinese medicine (TCM) symptom scale and fatigue self-assessment scale. Results: Of the 180 patients, 174 completed the full study. After 4 weeks of KRG treatment, the Fire-heat symptoms score including Excess fire-heat score and Deficient fire-heat score showed no significant change as compared with placebo treatment, and no clinically significant changes in any safety parameter were observed. Based on the TCM syndrome score and fatigue self-assessment score, TCM symptoms and fatigue were greatly improved after treatment with KRG, which showed a dose- and time-dependent effect. The total effective rate was also significantly increased in the KRG groups. Conclusion: Our study revealed that KRG has a potent antifatigue effect without significant adverse effects in people with deficiency syndrome. Although a larger sample size and longer treatment may be required for a more definite conclusion, this clinical trial is the first to disprove the common conception of "fireness" related to KRG.
