Elevated erythrocyte sedimentation rate and thrombocytosis as possible indicators of active disease in Langerhans' cell histiocytosis

Langerhans' cell histiocytosis (LCH) is a disease with an unpredictable course and unpredictable reactivations. Since active disease may cause life-long sequelae, early detection of reactivation is important. The usefulness of erythrocyte sedimentation rate (ESR) and thrombocytosis as indicators of disease activity in patients with LCH were examined. The mean values for ESR and platelet count for each quarter of a year were compiled. The means of all the ESR estimates (n = 76) during each quarter of a year with active disease was 21 mm h(-1), with intermediate disease activity 11 mm h(-1) and with resolution 7 mm h(-1). The corresponding platelet count estimates (n = 139) were 433 x 10(9) l(-1), 365 x 10(9) l(-1) and 304 x 10(9) l(-1), respectively. In conclusion, elevated ESR and platelet count may be clinically valuable indicators of disease activity in LCH.     

The erythrocyte sedimentation rate. Still a helpful test when used judiciously

ESR is a time-honored, simple, inexpensive test, but unfortunately it lacks sensitivity and specificity. Clinicians need to be aware of appropriate uses, because any test is expensive when ordered often, and evaluation of false-positive results may incur substantial costs and place the patient at risk from additional procedures. ESR should not be used to screen asymptomatic persons for disease. If an increased ESR is encountered and no explanation is immediately apparent, clinicians should repeat the test in several months rather than pursue an exhaustive search for occult disease. ESR may be useful in establishing a "sickness index" in elderly persons who have nonspecific changes in health status and a moderate probability of underlying disease; in screening for infection in specific settings (e.g., orthopedic surgery, pediatrics, gynecology); in diagnosing and monitoring temporal arteritis, polymyalgia rheumatica, and possibly other rheumatic diseases; in monitoring patients with treated Hodgkin's disease; and in assessing iron deficiency in anemia of chronic disease (when correlated with serum ferritin level). An ESR value exceeding 100 mm/hr has a 90% predictive value for serious underlying disease, most often infection, collagen vascular disease, or metastatic tumor. In asymptomatic persons with a markedly elevated ESR value, a minimal number of tests usually reveal the cause.     

Ventricular perforation associated with central venous introducer-dilator systems

BACKGROUND: An erythrocyte sedimentation rate (ESR) of at least 40 mm/h is considered an important requisite for the diagnosis of polymyalgia rheumatica (PMR). However, the relative frequency and clinical features of PMR in patients without a significantly increased ESR are unclear. METHODS: We performed a retrospective study of patients diagnosed as having PMR at the rheumatology divisions of 3 teaching hospitals. The diagnosis of PMR was established, regardless of the ESR, in 201 consecutive patients fulfilling the following criteria: (1) age 50 years or older, (2) severe proximal pain for more than 1 month in at least 2 of 3 areas: neck, shoulder, and/or pelvic girdles, and (3) rapid resolution of the syndrome while taking low-dose prednisone. Patients with giant cell arteritis were previously excluded from the study. The frequency and clinical features of patients with PMR and an ESR lower than 40 mm/h were analyzed. A comparative study between these patients and those with high ESRs was performed. RESULTS: An ESR lower than 40 mm/h was found in 41 patients (20.4%). These patients were younger (P = .02), were more frequently men (P = .006), and experienced a lower frequency of fever (P = .003) and weight loss (P = .07). Furthermore, these patients were characterized by an absence of anemia (P = .002) and a lower frequency of abnormal protein electrophoresis results (P < .001). Otherwise, their clinical syndrome, response to therapy, and frequency of relapses were similar to those of patients with classic PMR. In the entire population of 201 patients, the ESR was related to the length of treatment, number of areas involved, presence of fever, weight loss, and laboratory test result abnormalities, but it was unrelated to the duration of the illness prior to diagnosis. CONCLUSIONS: It is not uncommon to find a patient with PMR with an ESR lower than 40 mm/h. This syndrome is more frequent in men and it is clinically less severe than the classic form of PMR. Its recognition will allow these patients to benefit from an effective treatment with low-dose corticosteroids.     

The dilemma of prostate cancer--a growing human and economic burden irrespective of treatment strategies

The prognostic value of the erythrocyte sedimentation rate (ESR) was investigated in a population-based prostate cancer study, comparing 556 patients treated with no intent to cure. The data originated from hospital charts and death certificates. A statistically significant relationship between ESR at diagnosis and overall as well as disease-specific survival was demonstrated by univariate and multivariate analyses. A similar result was demonstrated in the 179 patients suffering from clinically organ-confined (T1-2,Nx,M0) disease. In a subpopulation consisting entirely of clinically organ-confined, small (T1), well-differentiated tumors, the dichotomized ESR (< or =20 mm/h vs. >20 mm/h) at the time of diagnosis distinguished between aggressive and non-aggressive tumors. In a small, second prostate cancer population it was demonstrated that ESR was not a surrogate marker for prostate- specific antigen (PSA). Our results indicate that ESR is a significant predictor of survival in early localized prostate cancer.     

Study of erythrocyte sedimentation rate in patients with pulmonary tuberculosis

We studied the erythrocyte sedimentation rate (ERS) and related factors that influence ESR in 326 patients with Pulmonary tuberculosis. The ESR tended to be higher for aged subjects and showed a difference between patients under 59 years old and patients over 60 years old. Besides, patients under 30 years old tended to present lower ESR. It is suggested that they may be under the influence of inapparent infection. For The Japanese Society for Tuberculosis Classification, a significant difference was noted in the extent, but there was no difference about the presence of cavity. A significant correlation was detected between ESE and Gaffky scale, ESR and CRP, and ESR and period until sputum culture became negative. But CRP negative cases were observed in about 28%. CRP alone was not sufficient for the evaluation of the morbid condition of Mycobacterium infection. Receiver-Operator Characteristic curve analysis confirmed that ESR is useful among patients with pulmonary tuberculosis. Therefore evaluation of ESR together with CRP was needed.     

Epidemiologic and actual importance of entero-hemorrhagic E. coli in Northern Bavaria (1996)

OBJECTIVES: To compare peripheral type 1 (T1) and type 2 (T2) T cell activities in rheumatoid arthritis (RA) patients with that found for osteoarthritic (OA) patients and healthy controls and to correlate peripheral T1/T2 cell activity in RA with parameters of the disease. METHODS: Peripheral blood mononuclear cells were isolated from patients with RA (n = 66), OA (n = 19), and healthy controls (n = 15). Primary T cell activity in these mononuclear cells was enhanced by means of anti-CD3/anti-CD28, which mimicks stimulation of T cells by activation of the T cell receptor and a major co-stimulatory signal. Interferon gamma (IFN gamma) production and interleukin 4 (IL4) production in the three groups were quantified as measures of T1 and T2 cell activity, respectively, and compared. Serum tumour necrosis factor alpha (TNF alpha), erythrocyte sedimentation rate (ESR), C reactive protein (CRP), and joint destruction assessed radiographically of RA patients were determined as parameters of disease activity and correlated with T1/T2 cell activity. RESULTS: Peripheral T cells from RA patients produced significantly less IFN gamma and more IL4 than T cells from both age and sex matched OA patients and healthy controls. Moreover, in RA patients both a decrease in IFN gamma and an increase in IL4 production correlated with an increase in serum TNF alpha, ESR, CRP, and joint destruction. CONCLUSIONS: These results suggest a role for differential T cell activity in RA. In view of the intra-articular T1 cell predominance the results might be explained by selective T1 cell migration into the joint or peripheral suppression of T1 cell activity.     

Prevalence of Borrelia burgdorferi serum antibodies in 651 patients with predominantly neurologic diseases

An analysis was undertaken to the records of 651 patients (median age 51 years, range 1-91; 334 male and 317 female patients), who were admitted for various reasons to the department of neurology and psychosomatics of the county hospital in Villach (K?rnten, Austria), over the period of one year. The clinical diagnoses were mostly neurological and psychiatric (n = 599), involving 25 different conditions. Other diagnoses (n = 52) comprised a group of 13 various conditions. Sera of all these patients were tested for antibodies to Borrelia burgdorferi. Overall seropositivity was 37.8%. Seropositivity increased significantly with age (p < 0.01). Seroprevalence exceeded 40% in patients with meningitis, paresis of the cranial nerves, cervical syndrome, pareses and sponylitis. The erythrocyte sedimentation rate (ESR) was raised in 37.9% of cases which was not related to seropositivity. ESR was significantly increased in patients with lumbago (p < 0.01) and with arthritis (p < 0.05). Antibiotics and dosages used were recorded in 164 cases. All these cases improved after therapy. Of 81 patients with a history of tick bite, 43 (53%) were seropositive. This is a significantly higher incidence than that of patients without tick bites (p < 0.01). The retrospective evaluation of patients' records showed that anamnestic and clinical findings alone do not suffice to establish the specific diagnosis of Lyme borreliosis and, hence, do not provide the indication of appropriate therapy. Furthermore, the mere demonstration of serum antibodies to Borrelia burgdorferi does not give information on the current state of infection. In case of a suspected Borrelia burgdorferi infection confirmatory tests are needed.(ABSTRACT TRUNCATED AT 250 WORDS)     

Psychiatric aspects of temporal arteritis: a case report and review of the literature

Temporal arteritis may present with atypical manifestations that can hamper its diagnosis. We report a case presenting with predominantly psychiatric symptoms including psychotic features and affective symptoms both on a background of cognitive impairment. Such clear-cut psychotic symptoms have not been described previously in the literature. Corticosteroid treatment was followed by full remission of psychotic and affective symptoms; treatment with antipsychotic medication was unnecessary. Temporal arteritis should be considered in the differential diagnosis of psychosis and affective disorder in the elderly. The erythrocyte sedimentation rate is a valuable parameter in the assessment of old-age psychiatry patients presenting both with functional and neurologic disorders.     

Diagnostic utility of Wada Memory Asymmetries: Sensitivity, specificity, and likelihood ratio characterization.

The authors used logistic regression, dichotomous and multiple level likelihood ratios, and receiver operating characteristic (ROC) analyses to examine Wada Memory Asymmetries (WMAs) in 324 patients who subsequently underwent temporal lobe (TL) surgery (left TL surgery = 172; right TL surgery = 152) using the Medical College of Georgia Wada protocol. Logistic regression correctly classified 84% of left TL patients and 77% of right TL patients using WMA. Corresponding dichotomous likelihood ratios (LRs) were: LR+ = 3.64; LR? = 0.21. The area under the curve using ROC was similarly highly significant (.886, standard error = .018, p     

Clinical criteria for acute maxillary sinusitis in general practice

The purpose of the investigation was to examine the diagnostic value of various symptoms, clinical findings, erythrocyte sedimentation rate (ESR) and serum C-reactive protein (CRP) in acute maxillary sinusitis using the aspiration of purulent or mucopurulent from the sinus of a patient with a pathological CT-scanning as the golden standard. Of 174 patients with suspected acute maxillary sinusitis seen in general practice we found 70% to have a pathological CT-scanning and 53% to have pus or mucous pus in the sinus aspirate. Only the ESR and CRP level were found to be significantly and independently associated with a positive diagnosis as defined by the golden standard. A clinical criterion based on either an elevated ESR and/or CRP level in a patient with pain related to the maxillary sinus region had sensitivity of 0.82, a specificity of 0.57, a positive predictive value of 0.68 and a negative predictive value of 0.75, and was diagnostically superior to the clinical examination. The investigation also confirms that this disease is most likely overdiagnosed in general practice.     

Symptom-specific use of upper gastrointestinal endoscopy in human immunodeficiency virus-infected patients yields high dividends

The yield of upper gastrointestinal endoscopy (esophago-gastroduodenoscopy; EGD) in human immunodeficiency virus (HIV)-infected patients based on presenting symptoms has not been well studied. We studied consecutive patients with documented HIV infection undergoing EGD at a large innercity hospital between August 1, 1990 and December 31, 1993; all had presenting symptoms and indications for EGD prospectively recorded at the time of EGD. All endoscopic abnormalities were routinely subjected to biopsy, and extensive histopathological evaluation was performed. EGD was considered helpful when the findings stimulated specific therapeutic intervention other than antifungal or antacid medications. The specific indications for EGD in 156 patients were as follows: esophageal symptoms, 102 patients (65%); abdominal pain, 18 (12%); upper gastrointestinal bleeding, 25 (16%); refractory nausea and vomiting, 11 (7%). Overall, pathologic findings were identified in 116 patients (74%): in refractory esophageal symptoms, 82%; upper gastrointestinal bleeding, 92%; abdominal pain, 39%; nausea and vomiting, 27%. EGD with biopsy identified a specifically treatable opportunistic disorder other than Candida in 80 patients (51%), including idiopathic esophageal ulcer (22%) or viral esophagitis and/or duodenitis (29%). EGD was not helpful in 22.3% of cases, those involving Candida (12.3%) and peptic ulcer disease (PUD)-related causes (10%). The mean CD4 count of patients with opportunistic pathologic findings (24/mm3, n = 79) was significantly lower than that of patients with PUD/gastroesophageal reflux disease (GERD) (167/mm3, n = 9) or negative EGDs (165/mm3, n = 35). Overall, the results of EGD influenced patient management in 78% of cases. We conclude that selective symptom-specific use of EGD, particularly in patients with esophageal symptoms refractory to antifungal therapy or gastrointestinal bleeding, usually identifies specifically treatable abnormalities, whereas EGD is less useful for the evaluation of abdominal pain or nausea and vomiting.     

Involvement of protein kinase C-delta in CD28-triggered cytotoxicity mediated by a human leukaemic cell line YT

Is shown, that the process of red blood sedimentation under the conditions of standard measurement of a clinical parameter ESR (erythrocyte sedimentation rate) is multistage and non-monotonous. Red blood sedimentation is preceded by the "latent" period lasting up to tens of minutes. When sedimentation begins, multiple accelerations and decelerations in the movement of the boundary between red blood and clean plasma are observed. The differences in dynamics of red blood sedimentation (DRBS) of healthy donors and patients with sharp myocardial infarction are revealed. The form of DRBS diagrams depends upon metabolic activity of blood. We suggest that DRBS represents the active reaction of blood, as of an integral surviving tissue, on stress factors acting on it under the conditions of ESR determination.     

Autonomous cell death of mouse male germ cells during fetal and postnatal period

OBJECTIVE: To determine the utility of CT-determined main pulmonary artery diameter (MPAD) for predicting pulmonary hypertension (PH) in patients with parenchymal lung disease. DESIGN: Retrospective review of right-heart hemodynamic data and chest CT scans in 45 patients. SETTING: Tertiary-referral teaching hospital and VA hospital. PATIENTS: Between October 1990 and December 1995, 36 patients referred for evaluation of parenchymal lung disease or possible pulmonary vascular disease were found to have PH, as defined by mean pulmonary artery pressure (mPAP) > or =20 mm Hg. Nine control patients (mPAP <20 mm Hg) were also identified (4 from hospital records search, 5 after evaluation for possible PH). RESULTS: CT-determined MPAD was 35+/-6 mm in patients with PH and 27+/-2 mm in control subjects. In our group of patients, MPAD > or =29 mm had a sensitivity of 87%, specificity of 89%, positive predictive value (PPV) of 0.97, and positive likelihood ratio (LR) of 7.91 for predicting PH; in the subgroup of patients with parenchymal lung disease (n=28, PH and control subjects), MPAD > or =29 mm had a sensitivity of 84%, specificity of 75%, PPV of 0.95, and positive LR of 3.36 for predicting PH. The most specific findings for the presence of PH were both MPAD > or =29 mm and segmental artery-to-bronchus ratio > 1:1 in three or four lobes (specificity, 100%). There was no linear correlation between the degree of PH and MPAD (r=0.124). CONCLUSIONS: CT-determined MPAD has excellent diagnostic value for detection of PH in patients with advanced lung disease. Therefore, standard chest CT scans can be used to screen for PH as a cause of exertional limitation in patients with parenchymal lung disease. Because CT is commonly used to evaluate parenchymal lung disease, this information is readily available.     

Suturing forceps for microsurgery

One hundred sixty-nine adult patients admitted to McPherson Hospital for elective eye or ear, nose, and throat surgery had erythrocyte sedimentation rates (ESRs) performed by the Wintrobe method, in addition to the usual admission laboratory work. The patients were selected for study if they had no known disease or were not receiving any medication that affects the sedimentation rate. The results showed that the mean ESR rose with each decade of life.     

Is parathyroid hormone-related protein a sensitive serum marker in advanced breast cancer?

BACKGROUND: To compare already used serum markers in advanced breast cancer, namely erythrocyte sedimentation rate (ESR), carcino-embryonic antigen (CEA), and polymorphic epithelial mucins (e.g. CA15-3) with a newer potential marker: parathyroid hormone related protein (PTHrP). METHODS: A study group of 33 patients of proven advanced breast cancer was compared with 11 patients with benign breast lumps who were undergoing surgery, and eight patients with humoral hypercalcaemia of malignancy of non-breast origin. ESR, CA15-3, CEA, PTHrP, parathormone (PTH), liver and renal function were measured using commercially available kits. Using given reference ranges, results were classified into normal versus abnormal, and univariate statistical comparisons were made using Fisher's exact test. For multivariate analysis, absolute serum levels were used, and multivariate logistic regression models were employed. RESULTS: By univariate analysis, only CA15-3 (P = 0.007), and CEA (P = 0.004), were significant markers of metastatic disease. By multivariate analysis the only independently significant serum marker was CA15-3 (P = 0.043). PTHrP was neither a sensitive (22%) nor specific (90.1%) serum marker when compared to CEA or CA15-3. ESR was the most sensitive single serum marker (93%). An incidental finding of elevations of serum parathormone was found in as many patients as in the study group as there were elevations of PTHrP. CONCLUSIONS: PTHrP would not have revealed any patients with metastatic disease that would not have been predicted by any existing tumour markers including CA15-3, CEA and ESR. The finding of elevated PTH in as many patients as PTHrP indicates the possible need for a study inclusive of other polypeptide hormones as markers in advanced breast cancer.     

tRNA-guanine transglycosylase from Escherichia coli: recognition of full-length ''queuine-cognate'' tRNAs

OBJECTIVE: To determine clinical variables useful in predicting the prognosis of patients with early rheumatoid arthritis (RA) by investigating the relationship between clinical variables and radiological progression. METHODS: One hundred eighteen patients with early RA whose symptoms developed within the previous year were enrolled in a prospective study. Data from the 98 patients who completed the 2 year study were analyzed, using the number of erosive joints and Larsen's score as the outcome of RA. RESULTS: Increases in the number of erosive joints at 12 months after entry into the study were significantly correlated with the number of swollen joints (r = 0.510), erythrocyte sedimentation rate (ESR) (r = 0.404), and C-reactive protein (CRP) (r = 0.487) at 6 months. The same results were seen using Larsen's score as the measure of outcome. The average number of erosive joints or mean Larsen's score at 12 months was higher in patients whose levels of CRP were high at 6 months and suppressed by 12 months, but increased much less in patients whose levels of CRP were successfully suppressed by 6 months. More joint erosions were noted in patients with positive rheumatoid factor (RF) than in RF negative patients. CONCLUSION: Joint erosions appeared with a certain time lag after active synovitis. Earlier introduction of effective treatment is recommended for the prevention of RA joint damage. The presence of RF, number of swollen joints, ESR, and levels of CRP at 6 months after starting therapy are the most useful variables to predict radiological progression in patients with early RA.     

An open study of pamidronate in the treatment of refractory ankylosing spondylitis

OBJECTIVE: Bisphosphonates inhibit the development of delayed type hypersensitivity chronic inflammation and suppress inflammation and cartilage/bone erosion in diverse murine arthritis models. We evaluated antiinflammatory properties of the bisphosphonate pamidronate in patients with ankylosing spondylitis (AS) refractory to nonsteroidal antiinflammatory drugs. METHODS: Patients included 14 men and 2 women. The first group of 8 patients (Group 1) received pamidronate as a 30 mg intravenous infusion once a month for 3 months, followed by a 60 mg dose once a month for an additional 3 months. Eight additional patients (Group 2) received only the 60 mg dose once a month for 3 months. Clinical assessments included the BASDAI (Bath AS Disease Activity Index), BASFI (Functional Index), and BASMI (Metrology Index), and laboratory assessments hemoglobin and erythrocyte sedimentation rate (ESR) at baseline and one month after final 60 mg dose of pamidronate. Mean BASDAI score at study entry was 6.7 for both groups. RESULTS: A significant improvement was observed in disease activity score in Group 1 after 6 monthly infusions of pamidronate (mean BASDAI 4.21; p = 0.03), in the BASMI score (p = 0.01), and the ESR (p = 0.009). A significant improvement in the BASMI was noted in Group 2 patients (p = 0.007) after 3 monthly infusions of pamidronate, but not in the BASDAI score (mean 5.01; p = 0.07) or the ESR (p = 0.12). CONCLUSION: Preliminary data suggest pamidronate may possess antiinflammatory activity in patients with AS, particularly with prolonged administration; this agent deserves further evaluation in a controlled trial.     

The micro-erythrocyte sedimentation rate as a screening test for bacteraemia in young children with non-focal infections

The micro-erythrocyte sedimentation rate (micro-ESR) was evaluated in 349 patients without focal signs of infection with bacteraemia, bacteraemia/malaria, malaria (218) and fever of undetermined origin(100). There were significant differences between the diagnoses in their mean micro-ESR uncorrected for anaemia (F ratio = 3.66, p = 0.013 for one way analysis of variance). The sensitivity of uncorrected micro-ESR > 20mm/hr for bacteraemia was moderate (53%) and specificity was low (32%); for bacteraemia/malaria sensitivity was high (88%) but specificity was also low (33%). The positive predictive value of micro-ESR > 20mm/hr was low for bacteraemia (3%) and bacteraemia/malaria (6%) whereas the negative predictive value was high for bacteraemia (94%) and very high for bacteraemia/malaria (98%). We conclude that a low micro-ESR (< 20mm/hr) may be helpful in ruling out bacteraemia, especially bacteraemia/malaria, in young febrile children without focal signs.     

Nutritional status in active juvenile chronic arthritis not treated with steroids

Nutritional status and nutrient intake were assessed in 17 children with active juvenile chronic arthritis (JCA) who never received steroids and in 17 controls matched for age and sex. Five patients had systemic, seven polyarticular and five oligoarticular JCA. Values significantly below those of the controls were found in systemic patients for height (p<0.05), upper arm circumference (p<0.05) and arm muscle area (p<0.01), and in polyarticular subjects for arm muscle area (p<0.01). All patients had unremarkable anthropometric fat measurements. All anthropometric measurements were normal in oligoarticular patients. Twelve JCA patients had reduced serum iron (Fe), 6 reduced serum zinc (SZn), 14 reduced intra-erythrocytic zinc (EZn) and 2 reduced serum copper (SCu). SZn was inversely correlated with erythrocyte sedimentation rate (ESR) (p=0.023). EZn was inversely related to lymphocyte count (p=0.022). SCu was related to ESR (p=0.037) and to lymphocyte count (p=0.016). No significant difference in nutrient intake was found between patients and controls. Active JCA was associated with reduced muscular mass, Fe, SZn, EZn. These alterations did not depend on reduced nutrient intake.     

Tumor-host interaction in non-random metastatic pattern distribution

In a prospective study, white and red blood cell counts, hematocrit, erythrocyte sedimentation rate (ESR), albumin, alpha-1 acid glycoprotein, C-reactive protein (CRP), and transthyretin (TTR) values were determined by serial measurements during 23 days in 80 patients with an open fracture of the lower limb. Postoperative reference profiles were defined in 74 patients without septic complications. In the six remaining patients, serum CRP and TTR concentrations were found efficient for the early diagnosis of postoperative infections: a CRP/TTR mass concentration ratio higher than 0.6 from the 8th day after surgery was sensitive (100%) and specific (93%). Variations of CRP and TTR concentrations often preceded the clinical diagnosis in patients with early infection. ESR was found unreliable with regard to postoperative infection because of its high dependence with respect to red blood cell count.
