Several factors including age, malnutrition and co-morbidity may affect on low survival of peritoneal dialysis (PD) patients. However, there are few report about the medication effect on survival in PD patients. The aim of this study is to find influential factors including medication on survival of PD patients. We retrospectively analyzed by the chart review of 349 patients who started PD therapy in our hospital between October 1999 and September 2008. We excluded patients who had been dropped out, had not maintained PD therapy over 6 months, or had been switched to hemodialysis or kidney transplantation. Finally we enrolled 127 patients (male/female : 62/65, diabetes : 73 cases) and investigated their laboratory findings and medication at the three points (point1 : PD start, point2 : 6 months after PD start, point3 : 3 months before the date of death or last follow-up date of PD patients alive). Mean age of PD patients was 55.3±12.2 years and durations of PD were 44.1±20.6 months. The percent of 3 year-survival was 66.1%. Patients who had survived over 3 years were younger and much more treated with ACEI/ARB than patients who had survived under 3 years. Patients who had survived over 3 years were male dominant and had higher levels of serum creatinine and serum albumin at the point 2 and 3 than patients who had survived under 3 years. Patients who had been treated ACEI/ARB were younger (53.5±12.3 vs. 59.5±11.1 years, p=0.012), showed longer PD duration (47.1±19.5 vs. 37.1±21.4 months, p=0.011) and had higher systolic blood pressure (142.5±20.9 vs. 128.8±30.0 mmHg, p=0.017) at the point 3 than patients who had not been treated ACEI/ARB. Age (OR: 0.93, 95% CI: 0.89 - 0.97, p<0.001), male (OR: 2.67, 95% CI: 1.21 - 5.90, p=0.015), ACEI/ARB therapy (OR: 2.64, 95% CI: 1.17 - 5.96 p=0.019) and serum creatinine(OR: 1.39, 95% CI: 1.15 - 1.70 p=0.001) and serum albumin (OR: 3.34, 95% CI: 1.34-8.34 p=0.010) at the point 3 were significant influential factors for 3 year-survival on the univariate regression analysis. ACEI/ARB therapy, serum creatinine and serum albumin may be influential factors on the 3 year-survival in PD patients.

Bromocriptine 투여로 호전된 프로락틴분비 뇌하수체선종에 의한 항이뇨호르몬 부적절 분비 증후군 1예

서론: 항이뇨호르몬 부적절 분비 증후군 (Syndrome of Inappropriate Antidiuretic Hormone Secretion, SIADH)은 저나트륨혈증의 가장 흔한 원인 중 하나로, 그 진단기준에는 저나트륨혈증, 저장성 혈액, 고장성 소변, 탈수나 부종의 부재, 신장과 부신, 갑상선의 기능이 정상인 것이 포함된다. 뇌하수체 종양은 드물게 저나트륨혈증을 동반할 수 있는 것으로 알려져 있으며, 그 중 SIADH를 동반하는 경우는 극히 드문 것으 로 알려져 있다. 저자들은 SIADH 환자에서 추가적인 검사 시행 중 뇌하수체 선종을 발견하였고, 기능검사에서 프로락틴분비선종을 진단 후, bromocriptine 투여로 혈액검사 및 임상증상이 호전된 1예를 경험하였기에 보고하는 바이다. 증례: 47세 남자 환자가 오심, 구토를 호소 하여 내원하였다. 환자는 만성중이염으로 치료받은 것 외에는 특이 병력은 없었다. 내원 당시 의식은 기면상태였고, 활력징후는 혈압 120/80 mmHg, 맥박수 66회/min 호흡수 18회/분 체온 36℃였다. 환자는 탈수되어 있지 않았으며, 부종도 없었다. 검사실 소견에서 혈청 전해질 및 생화학 검사상 혈청 sodium 110 mEq/L, potassium 3.9 mEq/L, chloride 76mEq/L, 혈청 삼투압 농도 238 mOsm/kg, 소변 삼투압 농도 426 mOsm/kg, 소변내 sodium 143 mEq/L, 혈청 BUN 8 mg/dL, 혈청 creatinine 0.6 mg/dL, 혈청 요산 2.2 mg/dL이었다. 갑상선 및 부신 기능은 모두 정상이었다. 저나트륨혈증을 일으키는 다른 질환과의 감별과 확진을 위하여 수분부하검사를 시행하였고, 수분배설장애를 시사하는 소 견을 보여 SIADH를 확진하였다. 3% 고장성 식염수로 치료를 시작한 이후에도 임상양상, 검사실 소견의 호전 소견 보이지 않아서, 중추신경 계 염분 소모에 대한 검사 진행 중, 뇌 자기공명영상에서 터키안 위아래를 모두 침범하는 2.5 × 1.6 × 1.5 cm 크기의 뇌하수체 거대선종이 관찰되었다. 혈청 프로락틴이 470 ng/ml 이상으로 높게 측정되어 프로락틴분비선종에 합당하였다. Bromocriptine 투여 이후에 환자의 혈청 sodium이 135 mEq/L로 호전되는 양상을 보였고, 추적한 혈청 프로락틴도 감소하였으며, 임상증상도 호전되었다. 결론: 프로락틴분비 뇌하수 체선종과 동반된 SIADH는 매우 드물다. 본 증례는 수술적 치료가 아닌 내과적인 치료로 호전된 첫 번째 증례이다.
