BACKGROUND/AIMS: Primary thyroid disease is prevalent in chronic renal disease, especially in patients requiring chronic dialysis. However, the relationship between kidney function and the prevalence of primary thyroid disease has not been studied in Korea, a nation where the dietary iodine intake is excessive. METHODS: Retrospective data from 2201 consecutive adult patients who visited a health promotion center over the last 5 years were analyzed; specifically, 54 patients with chronic kidney disease not requiring hemodialysis and 64 adults treated with hemodialysis. The glomerular filtration rate (GFR) was estimated using the abbreviated Modification of Diet in Renal Disease equation. Multivariable logistic regression was used to evaluate the independent association between the prevalence of primary hypothyroidism and estimated GFR. RESULTS: The prevalence of overt hypothyroidism increased from 0.5% at an estimated GFR > 90 mL/min/1.73 m2 to 6.3% in end-stage renal disease requiring chronic dialysis (p < 0.001 for trend). Compared with participants with an estimated GFR > 60 mL/min/1.73 m2, those with an estimated GFR < 60 mL/min per 1.73 m2 had an increased odds of overt hypothyroidism after adjusting for age, gender, fasting blood glucose (FBS), and the total cholesterol (TC) and triglyceride (TG) concentrations. CONCLUSIONS: These findings suggest that overt primary hypothyroidism is relatively common (6.3%) among persons with chronic kidney disease requiring chronic dialysis, and it is independently associated with a progressively lower estimated GFR.

BACKGROUND: In the Korean healthcare system, medical care for HIV patients was provided by a few university affiliated hospitals. Access to these tertiary hospitals by homeless people living with HIV was difficult due to socioeconomic reasons. Consequently, proper treatment for homeless subjects living with HIV was not delivered in a timely manner. This study compares the degree of disease progression of HIV infection/AIDS between homeless and non-homeless patient groups. MATERIALS AND METHODS: Out of 605 HIV/AIDS patients who visited the Center for Infectious Disease, National Medical Center, Seoul, Korea from August 2003 to May 2010, 295 subjects were included for this study. Referred cases (n=310) were excluded. The study subjects were further classified into three socioeconomic groups: National Health Insurance beneficiaries, Medical Aids beneficiaries, and the homeless. Status of HIV/AIDS disease progress was evaluated by peripheral blood CD4 cell count and the presence of AIDS defining illnesses at the first visit. RESULTS: There were 220 National Health Insurance beneficiaries (male 94.1%), 45 Medical Aids beneficiaries (male 88.9%), and 30 homeless people (male 96.7%). CD4 cell counts of the homeless (median: 119/microL, interquartile range: 44-383/microL) were significantly lower than those of the National Health Insurance beneficiaries (median: 267/microL, interquartile range: 159-397/microL; P=0.024). In addition, the proportion of patients whose CD4 cell counts <200/microL was significantly higher in homeless subjects (53.3%) compared to those in the National Health Insurance beneficiaries (27.3%) and the Medical Aids beneficiaries (28.9%) (P=0.004; P=0.033 respectively). Also, the frequency of AIDS defining illnesses was higher in the homeless (73.3%) than for those in other groups (the Health Insurance beneficiaries: 24.5%; the Medical Aids beneficiaries: 40.0%) (P<0.001; P<0.005 respectively). CONCLUSIONS: Homeless people living with HIV tend to seek medical care in far advanced stage, which may attribute to poor prognoses. More organized and strategic interventions are necessary to find and treat homeless people living with HIV at the early stage.
