The postoperative lumbar spine: evaluation of epidural scar over a 1-year period

BACKGROUND: Results of antituberculous chemotherapy for Mycobacterium avium complex disease remain disappointing. Pulmonary resection during an early stage of the disease, therefore, may be beneficial to patients whose disease is localized and who can tolerate a resectional operation. METHODS: Thirty-three patients with localized M avium complex disease underwent 33 pulmonary resections between 1979 and 1996. There were 17 males and 16 females, with a mean age of 50 years (range, 30 to 69 years). Lobectomy was performed in 26 patients, pleuropneumonectomy in 1, segmentectomy in 5, and wedge resection in 1. RESULTS: There was no operative mortality. After pulmonary resection, 31 (94%) patients attained sputum-negative status. Bronchopleural fistula occurred in one patient who underwent a right upper lobectomy. There were two late deaths. A patient with bronchopleural fistula died of respiratory failure two years postoperatively. Another patient died of an unknown cause 12 years postoperatively. Of the 31 patients with negative sputum status postoperatively, only 2 patients (6%) had relapse at 1 and 9 years after operation. CONCLUSIONS: We recommend that patients with this disease be considered for pulmonary resection as early as possible.     

The present situation, treatment and prognosis of drug-resistant pulmonary tuberculosis. Cooperative Study Unit of Chemotherapy of Tuberculosis of the National Sanitoria in Japan

We studied 266 patients with drug-resistant pulmonary tuberculosis at national sanatoria in Japan. The patients included 218 men (mean age, 58 years) and 48 women (mean age, 62 years). The levels of isoniazid and rifampicin resistance were determined at 1 mcg/mL and 50 mcg/mL, respectively. The results were as follows. (1) Most patients with drug-resistant pulmonary tuberculosis were middle-aged or past middle-aged. (2) There were many cases of drug-resistant pulmonary tuberculosis in previously treated tuberculosis patients with active disease and several cases in previously untreated pulmonary tuberculosis patients. However, in some previously untreated patients active tuberculosis was convert relatively easily to inactive tuberculosis. (3) Concerning life style, bachelors who drank heavily were more likely to develop drug-resistant pulmonary tuberculosis. (4) Most cases of drug-resistant pulmonary tuberculosis had at least one cavity on chest radiographs. (5) Several patients with drug-resistant tuberculosis left the hospital against the advice of their attending doctors; therefore, it was difficult to treat their illnesses. (6) In more than half the cases in which Mycobacterium tuberculosis was resistant to isoniazid and rifampicin, tolerance to streptomycin and ethanbutol was also seen. (7) When patients with drug-resistant pulmonary tuberculosis continued to have tuberculous bacilli in their sputum after 3 months of chemotherapy, there was a tendency for them to expectorate tuberculous bacilli in their sputum. For these drug-resistant tuberculosis patients, we must pay attention not only to the medical aspects but also to the social aspects of their disease.     

Management of pulmonary tuberculosis suspects with negative sputum smears and normal or minimally abnormal chest radiographs in resource-poor settings

SETTING: Queen Elizabeth Central Hospital, Blantyre, Malawi. OBJECTIVES: 1) To determine the proportion of pulmonary tuberculosis (PTB) suspects with negative sputum smears and a normal/minimally abnormal chest radiograph (CXR) who are culture-positive for Mycobacterium tuberculosis, and 2) to determine how many develop smear or radiographic evidence of PTB (TB CXR) during follow-up. METHODS: PTB suspects with negative sputum smears and a normal/minimally abnormal CXR were given a second course of antibiotics and followed up at 3-week intervals over 3 months with repeat sputum smears and chest radiography. RESULTS: Of 79 patients (38 men and 41 women, mean age 33 years) with negative smears and a normal/minimally abnormal CXR, 16 (21%) were culture-positive for M. tuberculosis. Of 15 culture-positive patients who were alive and attended follow-up, seven (47%) developed a TB-CXR by 3 months. Of 41 culture-negative patients who were alive and attended follow-up, 13 (32%) developed a TB-CXR, including one patient who became sputum smear-positive. TB-CXRs were found only in patients with a cough. CONCLUSION: TB suspects with negative smears and normal/minimally abnormal CXRs in high human immunodeficiency virus (HIV) prevalent countries should be given a second course of antibiotics. If cough improves, patients can be advised not to return for further follow-up. If cough continues, patients should return for further follow-up with sputum smear examination and chest radiography. Approximately 50% of those who have culture-positive PTB will develop a TB-CXR by 3 months and can be identified if radiographic facilities are available.     

The use of sputum induction for establishing a diagnosis in patients with suspected pulmonary tuberculosis in Malawi

SETTING: There has been a marked increase in notified cases of smear-negative pulmonary tuberculosis in Malawi since 1986. One reason for this may be related to the difficulties of getting adequate samples of expectorated sputum from patients. Sputum induction with nebulized hypertonic saline may be a simple way of obtaining a better specimen. OBJECTIVE: To examine the value of sputum induction for detecting cases of smear-positive tuberculosis. DESIGN: Sputum induction was performed on 82 adults presenting to the Queen Elizabeth Central Hospital, Blantyre, Malawi with clinically suspected pulmonary tuberculosis who were expectorated sputum smear-negative or unproductive of sputum. The induced sputum smear was examined for acid-fast bacilli and cultured for mycobacteria. RESULTS: Sputum was successfully induced from 73 of the 82 patients (26 previously smear-negative and 47 previously unproductive). The induced sputum was smear-positive in 18 patients (5 previously smear-negative and 13 unproductive). Cultures were positive for Mycobacterium tuberculosis in the 18 smear-positive patients and a further 12 that had been smear-negative. 94 cases of smear-positive pulmonary tuberculosis were notified during the study period. 18 (19%) were as a result of sputum induction. CONCLUSION: Sputum induction is a useful technique for improving the case detection rate of smear-positive tuberculosis in Malawi.     

Treatment of pulmonary disease due to Mycobacterium kansasii: recent experience with rifampin

Records of 244 patients with Mycobacterium kansasii isolated from their sputum were reviewed. Of the 244 patients, 82 failed to meet study criteria and were excluded. Response to treatment and posttreatment follow-up was evaluated in 162 patients. Overall, 135 patients (83%) achieved negative sputum cultures within six months. Among 32 patients whose drug regimen included rifampin, all 32 (100%) had negative cultures at the fourth and fifth months, but two relapsed during the sixth month, with cultures resistant to 1.0 and 25 micrograms of rifampin/ml. Among 130 patients whose regimen did not include rifampin, negative sputum cultures were achieved by the sixth month in 101 (80%). In these patients, no significant influence could be attributed to (1) the use of three-drug vs. two-drug regimens; (2) the in vitro susceptibility of pretreatment cultures to isoniazid; (3) the coexistence of obstructive airway disease; or (4) the early use of pulmonary resection. The susceptibility of pretreatment cultures to streptomycin in those who received this drug may have influenced outcome. The late follow-up showed a cumulative relapse rate of 13% over five years in those who had achieved negative cultures initially, and the relapse rate did not appear to be influenced by pulmonary resection as part of the treatment.     

Surgical treatment of lung abscesses

The authors analysed a group of patients with lung abscesses that received surgical treatment, as well as the characteristics of their evolution. Seventeen patients with lung abscesses which underwent surgical therapy from 1984 to 1995 were analysed. The group was composed of 12 male and 5 female. The age varied from 25 to 78 years (mean-50.1 years). The etiologies were: post-pneumonic, tuberculosis, foreign-body, empyema. Two types of surgical procedures were performed: pulmonary resection and transthoracic drainage. The indication of surgery was based on the failure of clinical treatment, massive hemoptysis, pleural empyema and residual cavity wider than 2 cm after 6 weeks of clinical treatment. The patients with poor clinical conditions were selected to transthoracic drainage, the less invasive procedure. Most patients had a satisfactory post-operative evolution (58.9%). Five patients had complications (29.4%) as empyema and air leak for more than three weeks and two patients died (11.9%). Regarding the surgical technics, the pulmonary resection (lobectomy and segmentectomy) showed no morbidity and mortality. The usage of external chest tube drainage of the abscess had a morbidity of 40% and mortality of 20%. In conclusion, the complicated lung abscess is still a surgical pathology and the best approach seems to be the resection of the pulmonary segment affected. The drainage has specific indication, mainly in patients with deteriorating condition, but this procedure has high mortality and morbidity rates.     

Diagnosis of pulmonary tuberculosis by the amplicor test for Mycobacterium tuberculosis in induced sputum

The polymerase chain reaction (PCR) technique was compared with the conventional smear and culture method for the detection and identification of Mycobacterium tuberculosis in 25 induced sputa samples. Sputum induction was performed with an ultrasonic nebulizer using 3% hypertonic saline in 27 previously untreated patients suspected of active pulmonary tuberculosis clue to chest X-ray findings, but who were unable to spontaneously expectorate sputum. All patients received anti-tuberculosis drugs for at least 6 months after sputum induction. Two patients could not expectorate sputum after hypertonic saline inhalation. Microscopy failed to detect positive acid-fast bacilli in 25 induced sputa samples. Induced sputa were both PCR- and culture-positive for 10 patients, PCR-positive and culture-negative for 4 patients, and PCR-negative and culture-positive for 2 patients. These results suggest that the PCR method is useful in diagnosing tuberculosis in induced sputum, and that the results of PCR and culture Procedures can complement each other.     

Emergence of drug-resistant tuberculosis in Jerusalem: ten-year retrospective review

Drug-resistant tuberculosis (TB) has emerged as a worldwide problem. The annual incidence of TB has increased in Israel in the last decade, mainly due to successive waves of immigration. Few data are available on drug-resistant TB in Israel A 10-year retrospective review was conducted on all patients who had been infected with culture-proven Mycobacterium tuberculosis and had been admitted to our hospital. Forty-seven patients had culture-positive TB; 27 (57%) were male, 20 (43%) were female; mean age (+/- SD) was 56 +/- 23 years. Twenty patients (43%) had pulmonary TB. Three patients (6.4%) had single-drug resistance; 4 patients (8.5%) had multi-drug resistance. Six of the seven patients (86%) with drug-resistant TB had been diagnosed after 1990. Six of the 20 patients (30%) with pulmonary TB had drug-resistant organisms. Six of the 7 patients (86%) with drug-resistant TB had pulmonary infection, as compared to 15/40 (37%) of the patients with drug-susceptible TB (p < 0.001). Six of the 7 patients (86%) with drug-resistant TB had a history of TB. Fifteen percent (14.9%) of all new cases diagnosed with TB in our hospital in the last 10 years had drug-resistant M. tuberculosis. Thirty percent of patients with pulmonary TB had drug-resistant organisms. Drug-resistant TB has evidently emerged in Israel and poses a serious clinical and social threat. A strong case for directly-observed treatment in Israel should be made, especially since the incidence of TB here is still small.     

Cancer resection on the residual lung after pneumonectomy for bronchogenic carcinoma

BACKGROUND: After pneumonectomy for bronchogenic carcinoma, the residual lung may be the site of a new lung cancer or metastatic spread. METHODS: From 1989 to 1995, 13 patients with carcinoma on the residual lung after pneumonectomy for lung cancer were operated on. Three segmentectomies and 7 simple wedge resections were performed, 2 patients had multiple wedge resections, and 1 patient had an exploratory thoracotomy. Nine patients had a primary metachronous bronchogenic carcinoma, 3 had metastases from bronchogenic carcinoma, and no definite conclusion was reached in 1 case. RESULTS: No postoperative mortality was observed. Four patients had postoperative complications. The mean postoperative hospital stay was 14 days. Seven patients are alive, including 5 patients without evidence of disease. Six patients died of their disease, all with pulmonary recurrences. The overall median survival was 19 months, with a probability of survival at 3 years (Kaplan-Meier) of 46% (95% confidence interval, 22% to 73%). CONCLUSIONS: Limited pulmonary resection for lung cancer after pneumonectomy for bronchogenic carcinoma is feasible with very low morbidity. In highly selected patients, surgical resection might prolong survival.     

Neuropathogenesis induced by rhesus cytomegalovirus in fetal rhesus monkeys (Macaca mulatta)

In a double-blind study, 655 sputum specimens were obtained from individuals suspected of having tuberculosis and were analyzed for the presence of Mycobacterium tuberculosis and rifampin susceptibility with use of a polymerase chain reaction (PCR)-based universal heteroduplex generator assay (PCR/UHG-Rif). Of the specimens containing viable M. tuberculosis, 100% of the smear-positive (n = 41) and 50% of the smear-negative (n = 6) specimens tested positive for the organism by PCR/UHG-Rif. Nineteen of 537 culture-negative specimens tested positive for M. tuberculosis by PCR/UHG-Rif and were from patients with confirmed tuberculosis who were receiving antituberculosis therapy at the time of specimen collection. Thirty-five specimens contained nontuberculous mycobacteria and were negative by PCR/UHG-Rif. Genotypic evidence of rifampin resistance in five of six culture-confirmed, rifampin-resistant isolates was obtained by PCR/UHG-Rif, yielding a sensitivity and specificity for the assay of 83% and 98.2%, respectively. These results demonstrate the feasibility of using a PCR-based assay directly on sputum specimens for simultaneous detection of M. tuberculosis and rifampin susceptibility, and they suggest that patients with smear-positive, untreated tuberculosis and those presenting with suspected drug-resistant tuberculosis are the most appropriate groups for testing by PCR/UHG-Rif.     

M. tuberculosis molecular variation in CNS infection: evidence for strain-dependent neurovirulence

OBJECTIVE: To determine the molecular diversity among Mycobacterium tuberculosis isolates associated with central nervous system tuberculosis (CNS TB) in a defined cohort of HIV uninfected patients. DESIGN/METHODS: A retrospective analysis was performed of clinical and laboratory data for all patients with CNS TB diagnosed in Manitoba, Canada, between 1979 and 1996. Restriction fragment-length polymorphisms (RFLP) of archival isolates of M. tuberculosis from CNS TB patients were determined and interpreted against the frequency of different isolates from all TB patients in the years 1992 to 1996. RESULTS: Among 2,334 patients with active TB, CNS TB was diagnosed in 42 (1.8%); meningitis with or without tuberculoma in 76%; and tuberculoma alone in 24%. CNS TB patients were significantly more likely to be young (<40 years old), female, and of Aboriginal origin. Morbidity (fixed/recurrent CNS deficit) rate was 29% and mortality rate was 26%. An adverse outcome, either morbidity or mortality, was significantly more common in those with meningitis. RFLP analysis of isolates (n=19) from CNS TB patients revealed 13 distinct restriction patterns with a predominance of the type 1 pattern (n=6). The frequency of type 1 restriction pattern was significantly greater in patients with CNS TB compared to all TB patients in Manitoba. CONCLUSIONS: CNS TB continues to have a high morbidity and mortality despite modern methods of detection and treatment. Although several strains of M. tuberculosis cause CNS TB, the current study suggests that the occurrence of CNS TB may be strain-dependent.     

Catabolism of lipid-free recombinant apolipoprotein serum amyloid A by mouse macrophages in vitro results in removal of the amyloid fibril-forming amino terminus

A series of 101 consecutive patients undergoing pancreatic resection for cancer was retrospectively analyzed to define factors that may affect the immediate postoperative outcome. Overall morbidity and mortality were 28.7% and 10.9%, respectively, although these figures were greatly reduced during the last years; the complication rate dropped from 55.6% (1981-1987) to 20.0% (1993-1995) and the mortality from 16.7% to 6.7%. At univariate statistical analysis the patient characteristics (sex, age, American Society of Anesthesiologists [ASA] class, nutritional status, jaundice), tumor characteristics (site, size, TNM stage, and grading), and type of surgery were found not to affect postoperative morbidity and mortality. In contrast, a significantly lower rate of complications was observed in patients not undergoing gastric resection, in those who received 3 units or less of blood intraoperatively, and in subjects operated more recently (after 1990). At multivariate analysis the period when the operation was performed was the only independent variable that affected the immediate postoperative outcome. Among the examined factors, only the experience acquired over time regarding the intra- and perioperative treatment of these patients seems able to lower the rate of postoperative complications.     

Pulmonary tuberculosis in Harare, Zimbabwe: analysis by spoligotyping

BACKGROUND: Over the last 10 years there has been a fourfold increase in cases of tuberculosis in Harare, Zimbabwe. The use of molecular epidemiology to understand tuberculosis transmission in this epidemic has been hampered by the availability of suitable culture facilities. A study was therefore undertaken to explore the potential of spoligotyping, a polymerase chain reaction based technique that does not require tuberculosis culture. METHODS: Adults attending a chest clinic with clinical or radiological pulmonary tuberculosis and one smear positive sputum were enrolled over one month. Demographic, socioeconomic, and clinical data were gathered using a standardised questionnaire. Molecular fingerprinting of genomic DNA recovered from sputum was performed by spoligotyping. RESULTS: Sixty one subjects (median age 28 years (range 18-73); 61% men) were recruited and 57 provided adequate sputum samples. Recent rural-urban migration or immigration was not common; 40% of subjects lived in crowded living conditions. DNA suitable for spoligotyping was recovered from 28 patients and 20 different genotypes of Mycobacterium tuberculosis were identified. Fifteen patients were infected with an M tuberculosis strain shared by one or more individuals. Patients infected with a shared spoligotype were not closely linked geographically within Harare, but were more likely to live in overcrowded conditions (69% versus 23%; odds ratio 6.85 (95% CI 1.2 to 47), p = 0.026). Analysis of the patients' original rural family homes revealed two geographically related spoligotype clusters. CONCLUSIONS: Spoligotyping may yield valuable molecular typing information in populations where tuberculosis culture is not available. This novel technique requires further development and evaluation in larger epidemiological studies.     

Is fetal neurologic and physical development accelerated in preeclampsia?

Tuberculosis remains a major health problem worldwide. The current role of video-assisted thoracoscopic surgery (VATS) in the management of this condition is unclear. We reviewed our experience over a 36-month period from a single institution. Thirty-seven patients (26 male, 11 female, with age ranging from 22 days to 71 years), in whom the final diagnosis was tuberculosis, underwent VATS procedures. There were 12 pleural biopsies, 3 decortications, 12 wedge lung resections, 5 drainages of empyema, and 5 lobectomies. All the patients were studied prospectively. There were no mortality or intraoperative complications. The overall median postoperative hospital stay was 4 days (range, 2 to 35 days). Postoperative parenteral narcotics requirement (mean, 310 mg meperidine hydrochloride [Pethidine]) was significantly less than a historic group of 30 patients who underwent conventional thoracotomy for lung resection or empyema drainage for tuberculosis (mean, 875 mg). Postoperative complications include 2 persistent air leaks over 7 days (5.4%) and 1 wound infection (2.7%). We conclude the following: (1) VATS is safe and effective in achieving the diagnosis of tuberculosis through pleural biopsies or wedge lung resection of indeterminate pulmonary nodules; it is particularly useful for those patients who are debilitated, thus making them poor candidates for conventional open surgery; (2) in patients with trapped lung or tuberculous empyema, VATS could achieve full lung reexpansion with minimal morbidity; and (3) therapeutic lung resection using VATS in patients with tuberculosis is technically demanding and potentially hazardous. Its role is, at present, limited.     

Improved results in the management of surgical candidates with lung cancer

BACKGROUND: Perioperative mortality and morbidity after lung resection for carcinoma are generally reported to be 3% to 6% and 15% to 30%, respectively, and higher in the elderly and those with limited cardiopulmonary reserve. METHODS: To minimize this risk and extend the surgical option to more high-risk patients, we adopted a protocol in 1991 that included preoperative digitalis, subcutaneous heparin and venoocclusive stockings, aggressive perioperative pulmonary toilet, and video-directed limited resections for many patients with limited pulmonary reserve. In October 1996, we reviewed our results with 173 consecutive patients (median age, 60 years; range, 17 to 89 years) undergoing operation for suspected lung carcinoma. Forty-one patients were 70 years old or older, and 70 patients were considered high risk on the basis of advanced age (> or = 70 years), poor cardiac or pulmonary reserve, or serious medical comorbidity. Procedures included pneumonectomy (n = 31), lobectomy (n = 83), bilobectomy (n = 12), and limited resection (n = 45). Two patients had unresectable disease. RESULTS: Hospital mortality was 1.6% (3/173) and morbidity was experienced by 15% (26/173). Among the high-risk subgroup mortality was 4.2% (3/70) and morbidity was 20% (14/70; p < 0.03). For the older patients these values were 4.8% (2/41) and 17.9% (7/41), respectively. CONCLUSIONS: Morbidity and mortality from lung resections may be minimized with the perioperative management strategy outlined above. This would allow more high-risk patients to benefit from surgical resection, and do so with an acceptably low risk.     

Expression of type II cGMP-dependent protein kinase in rat kidney is regulated by dehydration and correlated with renin gene expression

To define the current indications for surgical management of pleuropulmonary tuberculosis and analyze the results of operative procedures, the records of 59 patients operated on between January 1987 and December 1993 were reviewed. Three patient categories were defined. Group I patients (n = 25) underwent operation for diagnostic purposes: solitary mediastinal node or mediastinal adenopathy associated with pulmonary lesions (n = 10), pulmonary infiltrates (n = 4), pulmonary nodules or masses (n = 10), or chronic pleurisy (n = 1). Postoperative mortality and morbidity rates in this group were both 4%. Group II patients (n = 18) underwent operation for active lesions: intrapulmonary cavity (n = 6), destroyed lung parenchyma (n = 6), or chronic loculated pleural effusion (n = 6). Postoperative morbidity and mortality rates were 16.6% and 5.5%, respectively. Group III patients (n = 16) underwent operation for a complication of therapy or for sequelae of previously "cured" tuberculosis: calcified pyothorax (n = 8), empyema (n = 2), fistulized nodes (n = 2), bronchiectasis (n = 3), or aspergilloma (n = 1). Morbidity and mortality rates in this group were 31.25% and 12.5%, respectively. Surgery continues to have both diagnostic and therapeutic indications for management of pleuropulmonary tuberculosis, despite the morbidity and mortality rates associated with operative procedures.     

Risk factors for postoperative morbidity

OBJECTIVE: Analysis of outcomes after coronary artery bypass grafting has focused on risk factors for operative mortality. Nonfatal perioperative morbidity is far more costly and more common after operation. To identify the risk factors that lead to postoperative morbidity, we evaluated 938 patients undergoing coronary artery bypass grafting at Albany Medical Center Hospital during 1993. METHODS: Multivariate statistical analysis was performed on preoperative patient variables to identify risk factors for either serious postoperative morbidity or increased hospital length of stay. Variables were considered both individually and in combination. For example, age was considered individually or in combination with other variables, including parameters of blood volume (i.e., age divided by red blood cell volume or Age/RBCVOL). Similar multivariate analysis was performed to identify independent risk factors for hospital mortality. RESULTS: In order of decreasing importance, the following patient variables were significantly associated with increased length of stay by stepwise Cox regression analysis: Age/RBCVOL, history of congestive heart failure, hypertension, femoral-popliteal peripheral vascular disease, chronic obstructive lung disease, and renal dysfunction. The combination variable, Age/RBCVOL, was an important risk factor for both increased length of stay and serious postoperative morbidity. Variables that were significant independent predictors of increased mortality, such as preoperative shock, and redo operation, were not risk factors for either serious morbidity or increased length of stay. CONCLUSIONS: We conclude that risk factors for postoperative morbidity are different from those for postoperative mortality. These results suggest that older patients with preoperative anemia and low blood volume who also have other comorbidities (congestive heart failure, stroke, chronic obstructive pulmonary disease, or hypertension) are at increased risk for postoperative complications. This allows identification of a high-risk cohort of patients who are likely candidates for interventions to lessen postoperative morbidity.     

Resection of the right middle lobe and lingula for mycobacterial infection

BACKGROUND: In a series of 229 patients infected with mycobacterial organisms, we noted a specific female phenotype that involves isolated infections of the middle lobe and lingula. METHODS: Thirteen patients were found to have infections of the middle lobe, lingula, or both. All of them were infected with Mycobacterium other then Mycobacterium tuberculosis, all were women, 12 of the 13 were slender, and most had variable combinations of skeletal abnormalities. All underwent resection of the middle lobe, lingula, or both. RESULTS: There were no operative deaths. Only 2 patients have had reactivation requiring additional antibiotic therapy. All patients have had a decreased number of pulmonary infections in the postoperative period. Anatomic findings at operation included a complete major fissure and at least a partially complete minor fissure with middle lobe resections or an elongated lingula. CONCLUSIONS: Mycobacterial infection of the middle lobe and lingula is primarily a disease of asthenic women and is often associated with skeletal abnormalities and complete fissures or an elongated lingula. We recommend that surgical intervention be performed early once the condition is identified.     

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.
