OBJECTIVES: Pneumocystis carinii pneumonia(PCP) is one of the most common life-threatening opportunistic infections in patients with acquired immunodeficiency syndrome(AIDS). This study reports the clinical charac teristics of PCP in the patients with AIDS and prognostic factors for short-term survival of them. METHODS: We investigated 43 patients of AIDS to evaluate the frequency of PCP in patients in AIDS by retrospective analysis, and classified the 17 patients with PCP into survivors and non-survivors to compare epide miology, clinical characteristics and laboratory findings. We also analyzed whether the these findings influenced the short-term survival in patients with PCP that was combined with AIDS. RESULTS: In this retrospective study of 43 patients of AIDS, the frequency of PCP in AIDS patients was relatively high as 17 patients(39%), of whom eight pa tients(47%) died of PCP. The epidemiologic findings such as age, route of human immunodeficiency virus(HIV) infection and co-existing disease were not significantly different between survivors and non-survivors. Coughing was the most common symptom and bilateral infiltrates of lung was the most common form in the chest X-ray examination. But these clinical features were similar in the both groups. Total lymphocyte count, CD4 cell count, serum albumin level and arterial oxygen tension were decreased and serum LDH was increased in patients with PCP that was the first episode in patients with AIDS. Lymphocyte and CD4 cell count were significantly lower in the non-survivor group (p=.002 and p=.03, respec tively). Survivors had higher serum albumin level and arterial oxygen tension than non-survivors (p=.02 and p=.04, respectively). And non-survivors were found to have higher serum LDH level than survivors (p=.02). CONCLUSION: Lymphocyte and CD4 cell counts, serum albumin and LDH, and arterial oxygen tension may be considered as the prognostic factors for short-term sur vival of patients with PCP that is combined with AIDS.

BACKGROUND: Serum potassium level assessment is one of the commonly requested laboratory tests. Hypokalemia is defined as a serum potassium level of less than 3.5 mEq/L. It can be potentially life-threatening when severe, due to its association with cardiac arrhythmia and sudden deaths. The aim of our study is to determine the prevalence and to define clinical characteristics of severe hypokalemia in internal medicine hospitalized patients. METHODS: From December 1999 to June 2000, the group with at least one recorded plasma potassium concentration of less than 3.0 mEq/L was selected in department of internal medicine, Pusan national university hospital. Routine records of age, sex and prevalence was collected. Severe hypokalemia is defined as a serum potassium concentration less than 2.6 mEq/L. This patients were retrospectively studied for discharge diagnosis, medications prescribed before and during hospital stay, hospital course and laboratory findings. RESULTS: There were 7.52% (235/3124) with at least one recorded potassium level of less than 3.0 mEq/L. Severe hypokalemia were 75 patients (2.4%). It were more likely to be female, but statically insignificant. Of the 75 patients, 59 patients (77.3%) had hypokalemia during hospitalization. Gastrointestinal loss of potassium was only 13.8% of the patients. The main causes were combination of iatrogenic factors, including the adminstration of intravenous fluids with insufficient or no potassium, malnutrition, and several drugs. The discharge diagnosis included infection 20 patients (26.6%), malignancy 19 patients (25.3%), gastointestinal disorders 8 patients (10.6%). And each of cardiovascular, respiratory and renal disorders have 7 patients (9.3%). In-hospital mortality was 34.6% (26/75) in severe hypokalemia. Compared to the alive group, death group showed statically significant decrease in serum albumin concentration (p<0.05). CONCLUSION: Severe hypokalemia is fatal electrolyte disorder. The most frequent cause of this lethal condition is drug therapy and intravenous fluids with insufficient or no potassium replacement. It can be prevented by regular potassium monitoring and appropriate potassium supplementation in risky hospitalized patients.

Neurofibromatosis type 1 is the most common neurocutaneous disorders and affects between 1/2,000 and 1/4,500 people. This occurs at any age and is hereditary disease with autosomal dominant fashion. Renovascular hypertension is major form of renal manifestation of the disease. There are few reported cases in Japan and Hungary of Recklinghausen's neurofibromatosis with several glomerular lesions but their relationship is not apparent. A 21-year-old man was admitted to the hospital because of general edema. On admission, the blood pressure was 130/ 80 mmHg and general edema was noted. He had a plexiform neuroma on right flank and multiple cafe- au-lait spots on chest and extremites. Laboratory findings were as follows : Hemoglobin 14.2 g/dL, AST 28 IU/L, ALT 12 IU/L, albumin 1.2 gm/dL, total cholesterol 533 mg/dL, urinary protein 4.0 gm/ day, C3 86.6 mg/dL, C4 19.9 mg/dL, HBs Ag/Ab (+/-), HBe Ag/Ab (+/-), HCV Ab (-), HBV DNA probe 6,000 pg/mL. Renal biopsy was performed and the histological findings were compatible with minimal change disease. The immunohistochemical method revealed that HBsAg was negative. We experienced a case of minimal change disease concurrent with Neurofibromatosis type 1, but their relationship is not clear. We report this case with a brief review.

BACKGROUND: We aimed to evaluate the performance of serum cystatin C-based equations in calculating the glomerular filtration rate (GFR) in patients with varying stages of chronic kidney disease (CKD). METHODS: Serum cystatin C and creatinine levels were measured in 615 CKD patients. The CKD stage was determined by the creatinine-based estimated GFR (eGFR) equation using the four-variable abbreviated Modification of Diet in Renal Disease equation suggested by the Kidney Disease Outcome Quality Initiative with the addition of a coefficient applicable to Korean populations (K-aMDRD). In each CKD stage, the ratio of serum cystatin C to creatinine was calculated and six different cystatin C-based equations were used to estimate GFR. Cystatin C-based eGFR and aMDRD eGFR values were compared using the paired t test, Pearson correlation test, and the Bland-Altman plot. RESULTS: The mean age of patients was 53.21+/-14.45 years; of the 615 patients, 346 were male. The serum cystatin C-to-creatinine ratio was inversely correlated with the CKD stage. Compared with the K-aMDRD values, the results of the Hoek, Filler, and Le Bricon's cystatin C-based eGFR equations were lower in CKD Stages 1-3 and higher in Stages 4 and 5. However, the results of the Orebro-cystatin (Gentian) equation [GFR=100/ScytC (mL/minute/1.73m2) - 14] were similar to those of the K-aMDRD equation in CKD Stages 4 and 5 (15.44+/-9.45 vs. 15.17+/-9.05mL/minute/1.73m2, respectively; P=0.722; bias=0.27+/-8.87). CONCLUSION: The eGFRs obtained from the six cystatin C-based equations differed widely. Therefore, further studies are required to determine the most accurate equation to estimate GFR in Koreans with CKD.

Allopurinol, a commonly prescribed medicine for the management of gout and hyperuricemia, may induce life-threatening hypersensitivity characterized by fever, eosinophilia, hepatitis, renal failure, and skin eruptions such as Stevens-Johnson syndrome or toxic epidermal necrolysis. Stevens-Johnson syndrome may rarely affect the gastrointestinal tract, associated with a poor prognosis. We have experienced a patient having allopurinol hypersensitivity syndrome (AHS) with esophageal ulcer bleeding. A 64-year-old man was admitted with ten-day history of widespread rash and fever. Six weeks before admission, he had symptoms of gouty arthritis, and he was treated with allopurinol and colchicine for 10 days. Complete blood count showed leukocytosis with eosinophilia and blood biochemistry showed impaired renal and hepatic function. The diagnosis of an AHS with Stevens-Johnson syndrome was made from the history and the typical clinical feature. Despite adequate hydration, steroid and immunoglobulin therapy, severe esophageal ulcer bleeding, sepsis and disseminated intravascular coagulation had been developed and the patient died 33 days after admission. Until now, there is no specific treatment for the AHS. The only means of minimizing the incidence of AHS is to limit the allopurinol therapy to accepted indications and to adjust the dosage for the patient's renal function.

A 42-year-old male was hospitalized with abdominal pain, dyspnea, and turbid peritoneal fluid. He was diagnosed with hypertension, diabetes and started continuous ambulatory peritoneal dialysis (CAPD) 11 months ago. He was treated with intraperitoneal cefazolin and ceftazidime, and then white blood cell counts of dialysate decreased. Incidentally, liver abscess was found in chest CT performed for the evaluation of dyspnea, and patient was febrile persistently. So percutaneous abscess drainage was done by pigtail catheter. We changed the antibiotics to ceftriaxone and metronidazole, and hemodialysis was started. Klebsiella pneumoniae was cultured from peritoneal fluid and blood simultaneously. We concluded that liver abscess is a primary cause of CAPD peritonitis.

PURPOSE: Acute poststreptococcal glomerulonephritis(PSGN) is a disease that affects primarily children, and is caused by immune complex-mediated injury after streptococcal infection. The retrospective study was carried out to characterize the clinicopathologic features of PSGN in elderly patients. METHODS: The twenty five patients were enrolled; who had been diagnosed as PSGN clinically and pathologically from 1995 to 1999 in Pusan National University Hospital. They were divided up into 2 groups according to age; younger group being 16 to 29 years old(n=16) and elderly group being 30 years or older(n=9). The age-related characteristics were analyzed by the paired T-test RESULTS: Renal functional impairments and decreased GFR were developed more frequently in elderly group. The pathological severity was more advanced in elderly group. But there was no difference in BUN, serum creatinine, serum albumin, 24-hour urine total protein, ASO, C3, IgG, IgA, IgM. CONCLUSION: Elderly patients with PSGN had a high incidence of renal functional impairment. Early recognition of PSGN in elderly patients with nephrotic syndromes or nephritis, thought to be the key role to improve the renal function.

OBJECTIVES: Gallium 67(Ga-67) scintigraphy has been used to diagnose inflammatory and neoplastic diseases. We undertook a study to determine the clinical value of Ga- 67 renal scan in patients with various glomerular diseases. METHODS: Ga-67 scintigraphy was performed in 48 patients with various biopsy proven forms of renal diseases. Renal uptake in 48 patients images was graded as follow: Grade 0 = not visualization at 48 hours: 1 = faintly visualize: 2 = equal to uptake in spine: 3 = greater than over the spine: 4 = greater than activity over the liver. RESULTS: 1) Of the 48 patients, 31 were male, and mean age was 32 years. 11 patients had hypertension and 29 patients had hematuria. 2) Positive scintigram were seen in 40 of 48(83%) cases. In results of renal biopsy, IgA nephropathy(IgAN) was 15 patients, minimal change disease(MCD) was 14, focal segmental glomerulosclerosis (FSGS) was 8, membranoproliferative glomerulonephritis (MPGN) was 3, lupus nephritis(LN) was 3, poststreptococcal glomerulonephritis(PSGN) was 3 and membranous glomerulonephritis(MGN) was 2. 3) In 26 patients (54%) with nephrotic-range proteinuria, Grade 2 or higher renal uptake was observed in 9 (75%) of MCD, 5(100%) of FSGS, 2(100%) of LN and 3(75%) of IgAN. 4) In comparision nephrotics with non-nephrotics at biopsy, renal Ga-67 uptake in who patients had nephrotic-range proteinuria was correlated with clinical severity determined by serum albumin, serum total cholesterol and 24 hours urine protein excretion. CONCLUSIONS: Renal Ga-67 scintigraphy may be able to be a predictor in the assessment for severity of nephrotic syndrome.

ANCA-associated vasculitis is one of the immunologic cause of diffuse alveolar hemorrhage (DAH). We experienced a rare case of recurrent DAH in a 67-year-old man with ANCA-associated vasculitis who had been on maintenance hemodialysis. Two years ago, he presented with renal failure and hemoptysis. Hemoptysis caused by DAH was resolved immediately and hemodialysis was applied because of persistent uremic symptom. On maintenance hemodialysis, three recurrences have happened so far. At present, oral prednisolone and oral cyclophosphamide are being maintained during outpatient follow-up. Our report suggests that the nephrologist must be concerned about the possibility of recurrent aleveolar hemorrhage in ANCA associated renal disease patients and consider immunosuppressive treatment, even though the patient has been on maintenance hemodialysis.
