Eleven cases of community-acquired Pneumocystis carinii pneumonia occurred between 1979 and 1981 prompted clinical immunologic evaluation the patients. Young men who were drug abusers (seven patients), homosexuals (six), or both (two) presented with pneumonia. Immunologic testing revealed that absolute lymphocyte counts, T-cell proliferation depressed, humoral immunity was intact. Of 11 patients, one found to have Kaposi's sarcoma, another had angioimmunoblastic lymphadenopathy. Eight...
Susceptibility of mice to experimental insulin-dependent diabetes as induced by multiple subdiabetogenic doses streptozotocin has been shown be strongly gender-dependent, males being much more susceptible than females. We examined this gender difference further in two strains genetically determine whether exogenous steroid sex hormones can both suppress the high susceptibility and potentiate low Our results show that, BALB/cBOM C57BL/6 mice, estrogens males. Conversely, normally...
A physiological explanation for sustained hyperosmolality was sought in a patient with histiocytosis. During 23 days of observation only sodium intake regulated at 100 mEq daily, elevation (mean 310 mOsm/kg water) and fluctuation (range 298-323) the fasting plasma osmolality were recorded. The presence endogenous vasopressin indicated by patient's ability to concentrate urine as high 710 water creatinine clearance 84 cc/min, dilution response alcohol. failure increasing fluid 6.2 liters...
Idiopathic focal segmental glomerulosclerosis (FSGS) is one of the leading causes nephrotic syndrome in adults and an important cause end-stage renal disease. Its incidence has dramatically increased last two decades it especially prevalent among black patients. The trend FSGS not been reported beyond 1997.We retrospectively reviewed all biopsies performed at our institution between 1986 2002 identified patients with diagnoses consistent primary glomerulopathy (PG), which included:...
Troponin I (TnI) is an effective marker for detecting myocardial injury, but the interpretation of levels in setting end-stage renal disease (ESRD) still unclear. TnI have been noted to be increased 5-18% asymptomatic haemodialysis (HD) patients with standard assays, newer-generation, high-sensitivity assays not examined. In addition, there limited data on variability over time as well effect HD levels. The aim this study was prospectively explore incidence a assay, and levels.We enrolled 51...
Obesity has been increasingly recognized as a risk factor for kidney disease and both proteinuria microalbuminuria have associated with obesity. The actual prevalence of in obese patients the United States (US) not clearly described literature. Furthermore, obesity is factors disease, such diabetes hypertension (HTN), albuminuria excluding these uncertain. In this study, we collected urine albumin/creatinine protein/creatinine ratios on undergoing bariatric surgery to determine without HTN....

Observations of serum uric acid levels in 22 male cirrhotics showed that the mean concentration urate was 4.18 ± 0.25, significantly lower than found age-matched, controls, 6.44 0.19 (<i>P</i><.001). Twenty-four-hour excretion measured ten patients from each group with similar to those parent were not different. Further study three disclosed ratio clearance creatinine increased, and data obtained after administration pyrazinamide suggested this increase resulted impaired tubular...
To evaluate the reliability of CD34/CD33 subset enumeration as a predictor hematopoietic repopulating potential in autologous blood stem-cell transplantation and to determine which patient treatment-related factors affect timing, quantity, type stem cells mobilized.We analyzed collections from 410 consecutive cancer patients who received mobilization therapy evaluated factors, including CD34+ quantities, that might influence engraftment kinetics transfusion requirements recipients.The...
Although clinical use of recombinant human erythropoietin (rHuEPO) since 1989 has improved anemia in most end-stage renal disease patients, there are still many hemodialysis patients unable to maintain an adequate hematocrit (HCT) without large doses rHuEPO. This suggests that is not solely a consequence rHuEPO deficiency, but may be due other factors including functional iron deficiency. Since the optimal prescription for replacement yet known, we evaluated effect intravenous dextran (IVFe)...

We performed a prospective study of 30 patients undergoing chronic hemodialysis to determine which 6 generally available diagnostic procedures provided the most useful information for assessment bone disease in patients. The were: routine biochemical measurements, N-terminal parathyroid hormone (N-PTH), radiographic analysis hands and clavicles, density determination by dual photon absorptiometry (DPA), deferoxamine stimulation test, iliac crest biopsy. Serum N-PTH was elevated 83% but not...
