Levels of serum phospholipase A2 (PLA2), serum amyloid A (SAA), polymorphonuclear granulocyte elastase (PMN elastase), and C-reactive protein (CRP) were determined at short intervals during the patient's hospitalization. The first specimen was obtained at the time of admission, and subsequent specimens were drawn at 8 h intervals for the first 48 h and then twice daily until death or convalescence. Calculations of the APACHE II score used the most deranged variables during the first 24 h of admission to assess patient outcome. Additional calculations of the APACHE II score at the time of each blood draw served as an indicator of patient status. The results indicate that during the first 24 h after admission none of the four examined biochemical parameters gives reliable information about the outcome. The APACHE II score provided the earliest indicator of patient outcome (83% sensitivity, 65% specificity). PMN elastase provided useful information first at 32 h (83% sensitivity, 45% specificity) and better at 132 h (86% sensitivity, 86% specificity). CRP was of intermediate use in predicting outcome initially at 72 h (83% sensitivity, 50% specificity) and later at 132 h (86% sensitivity, 93% specificity). PLA2 and SAA were not useful as early indicators of lethal outcome.","PeriodicalId":22408,"journal":{"name":"The clinical investigator","volume":"72 11","pages":"843-9"},"PeriodicalIF":0.0,"publicationDate":"1994-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF00190738","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18892423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We treated 32 patients aged between 15 and 63 years with drug-refractory familial hypercholesterolemia, treated once a week by immuno-specific LDL apheresis for 3 years in a controlled prospective and non-randomized trial; 25 patients (14 females and 11 males) completed the study. Noninvasive data were obtained by physical examination, 12-lead ECG and exercise testing. Invasive cardiological data were obtained by cardiac catheterization according to a standardized protocol in four cardiological centers. Left ventricular ejection fraction was calculated using planimetry. Coronary stenoses were measured quantitatively in 23 defined coronary segments by a panel of four investigators with an electronic digital caliper. In addition, overall coronary atherosclerosis was visually qualified. Final decisions on a classification into one of three groups (regression, no change, progression) of coronary atherosclerosis were based on panel consensus. Six cardiac events occurred throughout the study: percutaneous transluminal coronary angioplasty in one patient, coronary bypass grafting in three and two deaths. Statistical analysis of exercise testing yielded no significant change for maximum power and work capacity during the study period. Hemodynamic data revealed no significant change; mean ejection fraction was calculated as 65.8 +/- 15.9% at study entry and 67.0 +/- 12.7% at completion.

We evaluated the influence of morning versus evening administration of the drug in a randomized double-blind cross-over study including 15 essential hypertensives. Five patients had to be excluded from blood pressure analysis because of noncompliance (three cases) or intolerable side effects (two cases). To assess the exact duration of the antihypertensive efficacy noninvasive automatic ambulatory blood pressure monitoring was performed. After a placebo period patients were given 30 mg nifedipine GITS either at 1000 or 2200 hours. Twenty-four-hours systolic and diastolic blood pressure profiles documented a sustained antihypertensive effect of both nifedipine regimens throughout the whole period without affecting the circadian rhythm. Statistical analysis revealed no significant difference between morning and evening administration. Two patients stopped their medication because of intolerable side effects (fatigue and muscle cramps, respectively). Two more cases suffered from mild reversible headache which provoked no discontinuation of the drug. In conclusion our results document a sustained antihypertensive efficacy of 30 mg nifedipine GITS in patients with moderate essential hypertension.

Preselected Asian female patients (n = 150) aged 18-40 years (mean 22.5), with the clinical and biopsy-confirmed diagnosis of genital warts (mean 2.64), predominantly flat vaginal condylomas, were randomly allocated to 3 parallel groups.

Patients were instructed to inject 6 g of the either alloted placebo/active cream deep into the vagina thrice a day for 3 consecutive days (group A) or 4 consecutive days (group B) per week, and if not cured the same treatment was extended to 3 more weeks (maximum 4 weeks active treatment). To assess the clinical efficacy patients were examined on a week-to-week basis. A total clearance of warts (biopsy-confirmed) was evaluated as a complete cure. Patients cured during the treatment were spared further treatment and were requested to visit us after 16 weeks for relapse control. As for the remaining patients, empty tubes were collected, and similarly coded replacement tubes were given for further treatment (in total 588 tubes were used).

Some details of its physiological and pathophysiological role remain poorly defined. Experimental evidence suggests that the antiporter is involved in the regulation of cell volume. In the present study, we therefore investigated the activity of the lymphocyte Na+/H+ antiport in nine healthy volunteers following acute hypertonic (2.5%) saline infusion (4 mmol NaCl/kg over 120 min). Antiport activity was measured after acidifying the cells with Na+ propionate (5-40 mM) using the fluorescent dye bis-carboxyethyl carboxyfluorescein. Hypertonic saline induced significant increases in plasma osmolality (308.4 +/- 2.3 vs. 293.5 +/- 2.7 mOsm/kg; P < 0.01), serum Na+ (150.8 +/- 3.7 vs. 138.9 +/- 0.5 mmol/kg; P < 0.01), and Cl- concentrations (118.0 +/- 3.9 vs. 101.1 +/- 1.0 mmol/kg; P < 0.01). Extracellular hypertonicity was followed by a stimulated activity of the lymphocyte Na+/H+ antiport with an increase in the apparent Vmax values from 2.44 +/- 0.16 to 3.27 +/- 0.34 10(-3) s-1 (P < 0.01) and a slight rise in pK, from 6.81 +/- 0.03 to 6.87 +/- 0.03 (P < 0.05) after hypertonic saline. In addition to antiport activation, cytosolic alkalinization was observed with cytosolic pH values averaging 6.90 +/- 0.02 before and 6.99 +/- 0.02 (P < 0.01) after hypertonic saline. Our results show for the first time that acute extracellular hypertonicity in man due to hypertonic NaCl loading is associated with a stimulated lymphocyte Na+/H+ antiport activity and cytosolic alkalinization.","PeriodicalId":22408,"journal":{"name":"The clinical investigator","volume":"72 11","pages":"817-21"},"PeriodicalIF":0.0,"publicationDate":"1994-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF00190734","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18892460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
