Alveococcosis of the liver - strategy of surgical treatment with special focus on liver transplantation

BACKGROUND

Echinococcosis is a zoonosis caused by infestation with any of 4 (of the 16) members of the Echinococcus genus, namely Echinococcus granulosus, Echinococcus multilocularis, Echinococcus oligarthus, and Echinococcus vogelii. The aim of this retrospective analysis was to present the outcomes of patients undergoing liver resection and liver transplantation (LT) for E. multilocularis infection.

METHODS

A total of 44 patients who underwent surgical treatment of E. multilocularis infection in the period between 1989 and 2014 were included in the study cohort and retrospectively analyzed.

RESULTS

LT was performed in 22 patients (50.0%), including 4 of 26 patients undergoing initial non-transplant management. Non-transplant procedures comprised liver resection in 23 patients (88.5%), diagnostic laparoscopy in 2 (7.7%), and left adrenalectomy in 1 patient (3.8%). Post-transplantation survival rates were 90%, 85%, and 75% at 1, 5, and 10 years, respectively.

CONCLUSION

In conclusion, LT for E. multilocularis infection is a safe and effective treatment method.

Treatment of early hepatic artery thrombosis after liver transplantation

INTRODUCTION

Early hepatic artery thrombosis remains one of the major causes of graft failure and mortality in liver transplant recipients. It is the most frequent severe vascular complication after orthotopic liver transplantation (OLT) accounting for >50% of all arterial complications. Most patients need to be considered for urgent liver retransplantation.

MATERIALS AND METHODS

Among 911 OLTs in 862 from 1989 to 2011, we observed 23 cases (2.6%) of acute early hepatic artery thrombosis. Seventeen patients were qualified immediately for liver retransplantation, and 6 underwent endovascular therapies, including intra-arterial heparin infusion or percutaneous transluminal angioplasty with stent placement.

RESULTS

Among patients who were assigned to early liver retransplantation, 11/17 survived with 3 succumbling due to postoperative complications, including 1 portal vein thrombosis, and 3 succumbling on the waiting list. All patients who underwent endovascular therapy survived with an excellent result obtained in 1 who underwent treatment<24 hours after arterial thrombosis. In 2 patients we achieved a satisfactory result not requiring retransplantation, but 3 patients assigned to endovascular treatment>24 hours after arterial thrombosis needed to be reassigned to liver retransplantation because of poor results of endovascular treatment.

CONCLUSIONS

Endovascular treatment efforts should be made to rescue liver grafts through urgent revascularization depending on the patient's condition and the interventional expertise at the transplant center, reserving the option of retransplantation for graft failure or severe dysfunction.

Influence of selected factors on survival after liver retransplantation

OBJECTIVE

The aim of this study was to examine the survival of adult liver retransplant recipients depending on selected factors: time from the primary transplantation, cold ischemia time, indications for retransplantation, patient age and United Network for Organ Sharing (UNOS) status.

PATIENTS AND METHODS

Between December 1989 and March 2011, we performed 43 orthotopic liver retransplantations (re-OLTs) among patients aged 20-62 years including 24 women and 19 men. The cold ischemia time was 250-820 minutes. UNOS status before re-OLT: UNOS 1 (n=19; 44%) UNOS 2A (n=15; 35%), and UNOS 2B (n=4; 9%). The time from OLT to re-OLT was 1-2, 146 days. The indications for re-OLT were arterial thrombosis (n=14; 33%), anastomotic biliary complication (n=3; 7%), recurrence of the original disease (n=9; 21%), hepatic vein thrombosis (n=1; 2%), primary nonfunction (PNF) dysfunction (n=2; [5%] /6 [14%]), de novo hepatitis C cirrhosis (n=2; 5%) and other etiologies (n=6; 14%).

RESULTS

The 6-year survival among the primary OLT group was 80% compared with 58% among the re-OLT group (P=.0001). One-year survivals in the re-OLT group according to UNOS status 1, 2A, and 2B were 47%, 60%, and 75%, respectively (P=.475). There was a low negative correlation between survival time and time between OLT and re-OLT. There was a low positive correlation between survival time and cold ischemia time. There was a low negative correlation between survival time and patient age.

CONCLUSIONS

There was a significant difference in survival between OLT and re-OLT. There was a correlation between survival time and time to re-OLTx; a shorter time corresponded to longer survival. There was a poor correlation between survival time and patient age. UNOS status before re-OLT and indication for re-OLTx influenced survival.

Partial recessive IFN-γR1 deficiency: genetic, immunological and clinical features of 14 patients from 11 kindreds

We report a series of 14 patients from 11 kindreds with recessive partial (RP)-interferon (IFN)-γR1 deficiency. The I87T mutation was found in nine homozygous patients from Chile, Portugal and Poland, and the V63G mutation was found in five homozygous patients from the Canary Islands. Founder effects accounted for the recurrence of both mutations. The most recent common ancestors of the patients with the I87T and V63G mutations probably lived 1600 (875-2950) and 500 (200-1275) years ago, respectively. The two alleles confer phenotypes that are similar but differ in terms of IFN-γR1 levels and residual response to IFN-γ. The patients suffered from bacillus Calmette-Guérin-osis (n= 6), environmental mycobacteriosis (n= 6) or tuberculosis (n= 1). One patient did not suffer from mycobacterial infections but had disseminated salmonellosis, which was also present in two other patients. Age at onset of the first environmental mycobacterial disease differed widely between patients, with a mean value of 11.25 ± 9.13 years. Thirteen patients survived until the age of 14.82 ± 11.2 years, and one patient died at the age of 7 years, 9 days after the diagnosis of long-term Mycobacterium avium infection and the initiation of antimycobacterial treatment. Up to 10 patients are currently free of infection with no prophylaxis. The clinical heterogeneity of the 14 patients was not clearly related to either IFNGR1 genotype or the resulting cellular phenotype. RP-IFN-γR1 deficiency is, thus, more common than initially thought and should be considered in both children and adults with mild or severe mycobacterial diseases.

Angiogenic activity of sera from interstitial lung disease patients in relation to clinical and radiological changes

Objective

Clinical symptoms and radiological changes are useful in monitoring patients with interstitial lung diseases (ILD). Neovascularization participates in the pathogenesis of idiopathic pulmonary fibrosis and other ILD. The objective of the study was to examine the relationships between angiogenic activity of sera from ILD patients and clinical or radiological status.

Material and methods

Serum samples were obtained from 83 patients with sarcoidosis, 31 with idiopathic pulmonary fibrosis (IPF), 29 with hypersensitivity pneumonitis (HP), 16 with collagen diseases with pulmonary manifestation (CD), 13 with scleroderma (SCL), 14 with Wegener's granulomatosis (WG), 12 with pulmonary Langerhans cell histiocytosis (HIS), 12 with pneumoconiosis (PNC), 10 with drug-induced lung disease (DLD), 5 with cryptogenic organizing pneumonia (COP), and from 36 healthy volunteers. As an angiogenic test we used a cutaneous angiogenesis assay according to Sidky and Auerbach. Clinical status was evaluated using a special questionnaire. In all patients chest radiographs were performed.

Results

The angiogenic properties of sera from ILD differed depending on the clinical diagnosis. The strongest proangiogenic effect was induced by sera from patients with HP (mean number of new vessels 16.8), CD (16.6), sarcoidosis (16.3), IPF (16.2), and PNC (15.7). In the case of DLD (13.2), the effect was comparable to healthy controls (13.5). In contrast, sera from SCL (mean number of the vessels 10.5) and HIS patients (10.8) significantly inhibited angiogenesis compared with controls. The angiogenic activity of sera from patients with hilar or mediastinal lymph nodes involvement was higher than that of sera from patients with lung fibrosis. There were also differences in the serum angiogenic activity in relation to the severity of dyspnea.

Conclusions

The data showed that sera from ILD patients constitute a source of mediators modulating angiogenesis, but the pattern of reaction is different in various diseases. Sera from HP, sarcoidosis, IPF, and CD patients demonstrated the strongest proangiogenic activity. However, sera from SCL and HIS inhibit angiogenesis. Angiogenic activity of examined sera was related to the clinical and radiological changes.

Impact of tumor characteristic on the outcome of liver transplantation in patients with hepatocellular carcinoma

INTRODUCTION

Orthotopic liver transplantation (OLT) is a well-established treatment for cirrhotic patients with hepatocellular carcinoma (HCC) who meet the Milan criteria. The aim of this study was to identify predictors of survival among 65 patients with HCC in cirrhotic livers who underwent liver transplantation (OLT).

METHODS

From January 2001 to December 2008, we performed 655 OLT in 615 patients. HCC was diagnosed in 58 patients before OLT and in 65 by histological examination of the explanted livers; 74% of the patients met Milan criteria by histological examination.

RESULTS

The median follow-up was 27 months (range = 1-96). We analyzed patient age and gender, etiology of liver disease, Child score at transplantation, rejection episodes, tumor number/size, vascular invasion, and differentiation grade. There was no significant difference in survival among patients grouped according to the Model for End-stage Liver Disease staging system for HCC. The 5-year survival of patients with low differentiated (G3) HCC was significantly worse than that of those with moderately differentiated (G2) or well-differentiated (G1) HCC: 50%, 81%, and 86% respectively, (P < .01). Patients with microvascular invasion displayed a worse 5-year survival than those without vascular invasion (42% vs 80%; P < .01).

CONCLUSIONS

The analysis indicated that the histological grade of the tumors and evidences of microscopic vascular invasion were the most useful predictive factors for overall survival among patients with cirrhosis after liver transplantation for HCC.

Modulatory effect of sera from patients with various types of pulmonary fibrosis on mononuclear cell induced angiogenesis in relation to pulmonary function

Angiogenesis plays an important role in the pathogenesis of idiopathic pulmonary fibrosis. Pulmonary fibrosis occurs also in many diseases, such as other types of interstitial pneumonias or drug-induced pulmonary fibrosis. The aim of the study was to examine the effect of sera from patients with various types of pulmonary fibrosis on angiogenesis induced by human mononuclear cells (MNC) in relation to lung functions. The study population consisted of 32 patients with idiopathic pulmonary fibrosis (IPF), 11 patients with drug-induced pulmonary fibrosis (DIPF), 6 with cryptogenic organizing pneumonia (COP), and 20 healthy volunteers. An animal model of leukocyte-induced angiogenesis assay was used as an angiogenic test. Spirometry, whole-body plethysmography, static lung compliance (Cst), and diffusing capacity of the lung for CO (DL(CO)) were performed in all patients. Sera from IPF and COP patients significantly stimulated angiogenic activity of MNC, compared with sera from healthy donors and from DIPF patients (P<0.001). However, sera from healthy donors and DIPF significantly stimulated angiogenic activity of MNC compared with the control group with PBS (P<0.001). In all groups, a decrease in the mean value of Cst and DL(CO) was observed, but no significant correlation between VC, FEV(1), DL(CO), Cst, and angiogenic activity of sera from examined patients was found. Sera obtained from patients with pulmonary fibrosis constitute a source of mediators modulating angiogenesis, but the pattern of reaction is different in various diseases. The strongest reaction is observed in IPF and the weakest one in DIPF. The angiogenic activity of sera did not correlate with the pulmonary function of patients with pulmonary fibrosis.

[A case of a patient with idiopathic pulmonary arterial hypertension treated with lung transplantation: a "bumpy road" to success]

We describe a case of 29 year old man, a first Polish patient with idiopathic arterial hypertension (IPAH) listed from Poland and successfully treated with lung transplantation in Vienna. Time from diagnosis to lung transplant was merely 11 months. Rapid clinical deterioration required treatment with most of currently approved or emerging methods, including oral and parenteral prostacyclin analogues administration by inhalation and chronic subcutaneous infusion. Atrial balloon septostomy was used to bridge the patient to transplant. We describe multiple problems in providing pharmacotherapy and in arranging logistics for lung transplantation. Peri- and multiple post-transplantation complications including dehiscence of right main bronchial anastomosis and its successful therapy are also presented. We consider good long term outcome as assessed 26 months post transplantation as an encouragement for other attempts at lung transplantation in patients with IPAH and for development of this method of therapy in Poland.

Assessment of early biliary complications after orthotopic liver transplantation and their relationship to the technique of biliary reconstruction

INTRODUCTION

Biliary complications are known as the weak point of liver transplantation. Their occurrence can be related to the practice of drainage of the biliary anastomosis, the routine use of which was abandoned in June 2004. The aim of the study was to assess the incidence and type of biliary complications following orthotopic liver transplantation in relation to the technique of biliary anastomosis.

MATERIAL AND METHODS

We compared the results of two groups of adult liver transplant recipients: group I, recent 50 transplantations with biliary drainage (25 women: 25 men of age range: 17 to 63 years), and group II, first 50 transplantations without drainage (19 women and 31 men of age range, 20 to 65 years). We examined the problem of biliary complications and their influence on the further management of the patients. In both groups the main indications for transplantation were various types of cirrhosis as well as cholestatic diseases. In the majority of cases (n = 86) an end-to-end common bile duct anastomosis was performed and in 14 cases, hepaticojejunal anastomosis.

RESULTS

In group I, biliary complications requiring surgical or endoscopic intervention occurred in 10 (20%) recipients. In one case, biliary complications resulted in the need for retransplantation. In group II, biliary complications occurred in only four (8%) patients, none of which caused organ loss.

CONCLUSION

Cessation of biliary anastomosis drainage has reduced the occurrence of early biliary complications following orthotopic liver transplantation.

Early results of orthotopic liver transplantations using the technique of inferior vena cava anastomosis

INTRODUCTION

We compared early results of orthotopic liver transplantation (OLT) in adults using the classic versus piggyback technique of inferior vena cava anastomosis.

PATIENTS AND METHODS

We analyzed 100 consecutive patients who underwent OLT from 2000 to 2003. Group A included 50 patients operated with the classic technique with venovenous extracorporeal bypass, and group B, 50 patients with the piggyback technique. The age range of the patients in group A was 21 to 63 years (mean, 43.5 years) and in group B, 20 to 65 years (mean, 46 years). The gender F/M distribution in group A was 24/26 and in group B, 28/22. The indications for OLT were acute hepatic failure (8%), chronic liver insufficiency (77%), liver tumors (8%), metabolic diseases (5%), and Budd-Chiari syndrome (2%). The degrees of liver insufficiency evaluated according to the Child classification were A, 18; B, 52; and C, 30 patients. The urgency for OLT on the United Network for Organ Sharing (UNOS) scale was UNOS 1-group A, 2 patients; group B, 7 patients; UNOS 2a-group A, 7 patients; group B, 6 patients; UNOS 2b-group A, 29 patients; group B, 30 patients; UNOS 3-group A, 12 patients; group B, 7 patients.

RESULTS

The average cold ischemia time in group A was 530 minutes and in group B, 515 minutes. The average results on the 10th postoperative day: aspartate transaminase (AST)-group A, 52.5 U/L; group B, 54.5 U/L; alanine transaminase (ALT)-group A, 131.5 U/L; group B, 153 U/L; gamma glutyl transpeptidase (GGTP)-group A, 299 U/L; group B, 285.5 U/L; alkaline phosphatase (ALP)-group A, 164 U/L; group B, 150.5 U/L; bilirubin-group A, 4.37 mg%; group B, 2.71 mg%; activated partial thromboplastin time (APTT)-group A, 37.6 seconds; group B, 34.8 seconds; platelets (PLT)-group A, 167 10(2)/mm(2); group B, 171 10(2)/mm(2). The incidence of postoperative complications was 36% in group A; it was 30% in group B. The mean hospitalization times in the surgical department were 17 days in group A and 16 days in group B.

CONCLUSIONS

The early results, morbidity and mortality with both applied techniques were similar. Individualization in qualifying the patients for a given operative technique is important. The lower complication rate and reduced treatment cost of the piggyback technique group suggested advantages of this technique when compared with the classical OLT technique.

[Invasive aspergillosis (IA) in patients treated in the Institute of Tuberculosis and Chest Diseases in the years 1993-2005--diagnostic problems]

The aim of this study was to present the diagnostic problems in pts treated for invasive aspergillosis (IA) in the IIIrd Clinic of the Institute of Tuberculosis in the years 1993-2005. The material consisted of clinical documentation of 18 pts. 15 out of 18 pts (83,4%) died. In all those cases autopsy examination was done. In 13 pts IA was the main and in another 2 only the accessory cause of death. All pts were treated with corticosteroids and/or cytostatic drugs because of lung cancer (13 pts), haematologic disorders (1 pts), Wegener's granulomatosis (3 pts) and idiopathic pulmonary fibrosis (1 pts). In 13 out of 18 pts granulocytopenia was revealed (on an average from 0,008 x 10(9)/L to 0,95 x 10(9)/L) one month before death. In 13 pts IA was limited to the lungs, in 5 others there were also fungal lesions in brain, kidneys, liver, spleen, pleura, pericardium and heart. Pts with disseminated form of IA had significantly lower granulocyte count and were treated with higher doses of corticosteroids than others. Immunosupressive drugs and granulocytopenia can be regarded as predisposing factors. IA was diagnosed before death only in 5 out of 18 pts. This was mainly caused by the lack of the symptoms of infection (4 pts) and negative results of mycological (6 pts) and serological examination (8 pts). We should underline that mycological examination was only done in 11 pts and serological examination of blood for fungal antigen only in 6 pts. We conclude that mycological infection ought to be searched in all pts treated with high doses of corticosteroids and those with prolonged granulocytopenia, especially if they have the symptoms of infection which does not respond to antibiotic therapy.

Orthotopic Liver Transplantation for Fulminant Hepatic Failure

This paper presents the results of liver transplantation for fulminant hepatic failure in 31 patients qualified as UNOS-1 class (extra-urgent indication for transplantation), operated from January 1989 to April 2005. Twenty-one patients (61.8%) survived the 3-month postoperative period. Three-year survival rate with good liver graft function was 52.9% (18 patients). Before the transplantation, eight patients (23.5%) underwent hepatic dialysis using Fractionated Plasma Separation and Adsorption (FPSA) with the use of a Prometheus 4008H System. Liver transplantation remains the only life-saving procedure for the treatment of fulminant liver failure, regardless of its cause.

Disseminated Mycobacterium avium infection in a 20-year-old female with partial recessive IFNgammaR1 deficiency

We report the case of a 20-year-old female with disseminated Mycobacterium avium disease involving bones, lungs and brain. She was completely healthy up until the present illness and had been vaccinated with BCG in infancy without complications. Mycobacteriosis progressed in spite of treatment with antituberculous drugs and was controlled only after addition of interferon-gamma subcutaneously. A homozygous hypomorphic I87T mutation was found in the gene encoding the ligand-binding chain of the IFN-gamma receptor (IFNgammaR1). This mutation is the only known recessive hypomorphic lesion in IFNGR1 and had been reported before in only 1 child with curable BCG infection and his sibling with primary tuberculosis. Our report illustrates the clinical heterogeneity of patients sharing exactly the same form of partial recessive IFNgammaR1 deficiency. A diagnosis of partial recessive IFNgammaR1 deficiency should be contemplated in adults with unexplained environmental mycobacterial diseases.

[The significance of the serum tumour markers as a prognostic and predictor factors in nonsmall cell lung cancer patients]

The aim of the study was to assess the role of serum tumour markers (NSE, Cyfra 21-1, CEA, LDH, ferritin) as a prognostic and predictive factors in 79 patients with advanced NSCLC treated with chemotherapy. Objective response to treatment was significantly more frequent in the patient with serum NSE > 12.5 ng/ml. Progression of disease was observed more often in patients with serum Cyfra 21-1 >10 ng/ml or LDH >480 U/L. CEA >3 ng/ml, LDH >480 U/L, for coefficient >1, NSE >20 ng/ml and Cyfra 21-1 >10 ng/ml had a negative impact on survival in univariate analysis. Independent negative prognostic significance of fer coefficient >1 was confirmed by multivariate analysis.

Cellular components of the bronchoalveolar lavage correlate with lung function impairment and extrapulmonary involvement markers in active sarcoidosis

Sarcoidosis is a chronic inflammatory multiorgan disease of unknown origin. Our previous study demonstrated a significant correlation between the relative count of non CD4(+), non CD8(+) lymphocytes in bronchoalveolar lavage of active sarcoidosis patients and proangiogenic activity of BAL homogenates. The aim of the present study was to evaluate in a group of 40 patients with active sarcoidosis the possible relationship between the intensity of alveolitis, particularly the non CD4(+), non CD8(+) lymphocyte subset, and other parameters characterizing the level of pulmonary (lung function tests) and extrapulmonary (spleen longitudinal dimension) disease activity. We found that the relative count of non CD4(+), non CD8(+) lymphocytes in BAL correlated positively with spleen size (r=0.50, P<0.01) and negatively with static compliance (r=0.43, P<0.05). We concluded that the lymphocytes belonging to the non CD4(+)non CD8(+) subset participate in the inflammatory process in sarcoidosis. However, more detailed phenotypic and functional characteristics of this cellular population are needed.

Vascular complications after liver transplantation

Vascular complications following liver transplantation is reviewed based upon literature data and our own results. Our study conclusions are mostly based on literature data, because our center does not have the liver transplantation experience of other centers worldwide. Thus, we may conclude, that the number and character of complications does not differ from those reported by other centers. The enbloc technique used in liver harvesting minimizes the risk of arterial damage in case of vascular anomalies. Recipient retransplantation is the most effective treatment method in cases of hepatic arterial occlusion. Doppler ultrasound examinations are effective to monitor vascular blood flow in the transplanted liver.

[Organizing pneumonia--analysis of 18 own cases]

Organizing pneumonia (OP) is a rarely diagnosed disease, however the incidence ratio was estimated as 6-7/100000. Disease can occur in cryptogenic form or as a secondary reaction to various noxious agents, drugs, and ionising radiation, as a concomitant disease to infections, lympho- and myeloproliferative disorders, and connective tissue diseases. Symptoms of OP are non-specific therefore lung biopsy and histological examination are necessary for diagnosis. Eighteen cases of OP, 15 women and 3 men, aged 40 to 76 years, are presented with analysis of clinicopathological characteristic and therapeutic problems. In all cases diagnosis was confirmed by open lung biopsy. In one case radiotherapy and in one trastuzumab treatment was the cause of OP. In further 3 women antibodies against Chlamydia pneumoniae and in one--against Mycoplasma pneumoniae were found in serum. Probably Hashimoto disease was the cause of one case. In 12 patients the OP was idiopathic. Majority of patients were treated by prednisone (0.5 mg/kg). In one patient regression without any treatment was noticed and in other one--after cessation of trastuzumab. Five women were treated by clarithromycin. In 3 of them regression was observed but in other 2 corticotherapy was necessary. The observation period ranged from 1 month to 9 years, mean 34 months.

The impact of experience of a transplantation center on the outcomes of orthotopic liver transplantation

The so-called learning factor has been disregarded for many years in analyzing the causes of surgical complications and post-operative mortality; it is also the case for OLT. In our center until April 2003, 209 OLT were performed in 196 patients. We evaluated the impact of experience of the transplantation team on the outcomes of liver transplantation. Thirty-four patients died (mortality rate, 16%) and 1-year survival rate, 64%. Mortality rates varied during different periods of observation due to increasing experience of the transplantation team. The causes of mortality were assessed for a series of 34 patients: it was 75% at the beginning of transplantation procedures while recent deaths have not recently exceeded 10% of cases.

Bile duct variations in partial liver transplantations from living-related donors

The aim of this paper was to present anatomic variations of bile ducts and their effect on the perioperative course of living-related donors in partial liver transplantations in children. Liver fragments for partial transplantation were harvested from 41 related donors. Segments II and III were harvested from 35 and segments II, III, and IV from 6 donors. During the procedure, cholangiography through cystic duct was performed revealing a normal anatomy of the bile ducts in 33 (80.5%) cases. The rest of the donors showed anatomic variations. There was only one case of complications related to the bile duct. The intraoperative diagnosis of anatomic variations allowed for safe partial liver harvesting.

Comparison of the results of liver transplantation for elective versus urgent indications

The authors present an analysis of early and remote liver transplantation outcomes related to the presence of emergent indications among 196 of the 209 operations performed from 1989 to April 2003; namely 178 elective and 18 emergent transplantations. Perioperative mortality was 15%. The survival rate during the first 12 months was 79.8% and within 3 years 73.5% among patients operated on an elective basis (UNOS 3 and 2B). In contrast, patients with acute liver failure (UNOS 1 and 2A) showed rates of 45%, 50%, and 47%, respectively. Liver transplant outcomes depend primarily on the urgency of an operation. Longterm results are much better among patients operated on electively. Liver transplantation in patients with acute hepatic insufficiency is burdened with a high 45% mortality.

[Pulmonary mycobacterioses--frequency of occurrence, clinical spectrum and predisposing factors]

Various types of non-tuberculous mycobacteria can be the aetiologic factors of chronic lung infections especially in patients with underlying chronic lung diseases. The aim of this study is to present the cases of pulmonary mycobacterioses observed in Institute of Tuberculosis and Lung Diseases in the years 1995-2001. There were 23 patients, 12 men and 11 women in the age between 35-77 years, mean 56 years. 16 out of 23 patients had underlying respiratory problems, mainly healed tuberculosis (7) and COPD (6). Two additional patients suffered from other diseases with potential immunosuppression (leukopenia). In 5 patients no disease other than mycobacteriosis was found, but they were chronic smokers. In 19 cases cough and expectoration of purulent sputum lasting from several months to several years was observed. In 5 patients onset of disease was acute or subacute with high fever. Eight patients had haemoptysis. In chest X-ray pathological lesions including (18 cases) lung cirrhosis (10) and cavities (15) were found. In 4 cases disseminated bronchiectases with small nodules were the main radiologic feature. Mycobacteriosis was caused by M. kansasii in 11 cases, by M. intracellularae in 6, by M. xenopi in 5 and by M. scrofulaceum in 1 case.

[Invasive aspergillosis in autopsy material of patients treated at the Institute of Tuberculosis and Chest Diseases during the years 1993-2000]

The aim of this paper is an analysis of clinical documentation and results of autopsy of 21 patients (pts) who died of invasive aspergillosis (IA) in the Institute of Tuberculosis and Chest Diseases in years 1993-2000 and the assessment of predisposing factors for IA. In 17 pts IA was the main and in other 4 only an accessory cause of death. All pts were treated with corticosteroids and/or cytostatic drugs--because of lung cancer (11 pts), cancer in other site (2 pts), haematologic disorders (2 pts), Wegener's granulomatosis (1 pt), polymyositis (1 pt), idiopathic pulmonary fibrosis (1 pt) and other diseases (3 pts). In 15 out of 21 pts granulocytopenia was revealed (from 0.008 x 10(9)/L to 0.82 x 10(9)/L) on an average one month before death. In 15 pts IA was limited to the lungs, in 6 others there were also fungal lesions in brain, kidneys, liver, spleen and heart. Pts with disseminated form of IA had significantly lower granulocyte count and were treated with higher doses of corticosteroids than others. Immunosuppressive drugs and granulocytopenia can be regarded as predisposing factors. Fatal course of IA depended also on the late diagnosis.

[Prognosis in limited disease (LD) small cell lung cancer (SCLC) patients according to status performance, local extension of lesions, type of treatment and the completeness of staging]

The aim of this study was to assess the prognosis in LD SCLC pts according to their performance status, local extension of lesions, type of treatment and the completeness of staging. In the period 01.01.1986-31.12.1996 in the Institute of Tuberculosis and Chest Diseases 579 consecutive SCLC pts were treated. LD was diagnosed in 345 pts. In 193 out of them the staging was complete that is in addition to chest x-ray, abdomen USG/CT, brain CT/MRI and bilateral bone marrow trepanobiopsy was done. 152 pts were also regarded as limited but the staging was not complete. LD pts proved by complete staging survived significantly longer (median survival 15.7 months) than others (median survival 10.2 months). The pts in whom complete staging was done were however in better performance status and had smaller local extension of lesions and had more often radiotherapy than others. Status performance, local extension of lesions and radiotherapy but also completeness of staging were independent prognostic factors in multivariate analysis.

[Evaluation of mediastinal lymph nodes in the course of lung diseases in dynamic contrast-enhanced magnetic resonance imaging]

The purpose of this study was to evaluate the ability of dynamic contrast-enhanced magnetic resonance to provide differentiation between malignant and benign mediastinal or hilar lymph nodes. The group of 109 patients were examined, with lung carcinoma (63 patients) and sarcoidosis (46 patients). Relative signal intensity increase after administration of Gd-DTPA in standard dose (0.1 mmol/kg) was measured four times (20 s-3 min after injection). There was no significant difference between all groups. In conclusion, differentiation between types of enlarged lymph nodes could not be achieved using the described protocol.

[Pulmonary amyloidosis--own experience]

Three cases of amyloidosis were described. In all diagnosis was confirmed by histological examination. There was amyloidosis limited to the lungs in 2 cases and in 1 generalised. In 1 patient lobectomia was performed. Next 2 pts were treated with prednisone and cytostatic drugs (melphalane and cyclophosphamide).

[Sarcoid reaction in patients with lung neoplasm--personal experiments]

In two cases histological examination of the lymph nodes excised during mediastinoscopy showed non-caseous epithelioid granulomas. In one patient with hilar lymphadenopathy sarcoidosis was misdiagnosed. One-year later progression of lesions in lungs was found and adenocarcinoma was diagnosed. In second patient with tumour in chest x-ray examination after misdiagnosed sarcoidosis thoracotomy was done and histological examination of samples from tumour showed nonsmall cell lung cancer. In both carcinomatous cases sarcoid reaction was recognised.

[Extrapulmonary manifestations of sarcoidosis as the cause of primary symptoms--4 case reports]

Sarcoidosis is a multisystem disorder most frequently presenting with hilar lymphadenopathy, pulmonary infiltrations, ocular and skin lesions. However pulmonary manifestations typically dominate, any organ can be affected. Sometimes leading symptoms are caused by extrapulmonary manifestation of the disease, and together with the absence of typical picture in chest radiographs may be confusing for the physicians. We present 4 cases of proven sarcoidosis in which leading symptoms were caused by sarcoidal involvement of different organs (liver, spleen, heart and skin) without typical changes in the lung. In all cases multiorgan involvement was documented and disease was successfully treated.

Fatal infection in patients treated for small cell lung cancer in the Institute of Tuberculosis and Chest Diseases in the years 1980-1994

The study was performed to explore the frequency of infections present at death and infection as the main cause of death (fatal infection - FI) in 845 consecutive patients (pts) treated for small cell lung cancer (SCLC) at the Institute of Tuberculosis and Chest Diseases in Warsaw, in the period 1980-1994. Diagnosis of infection was based on clinical signs and symptoms, the presence of new lesions on the chest X-ray, microbiological tests and/or autopsy examination. All cases of fungal infection, Pneumocystis carinii pneumonia (PCP) and tuberculosis were proved by autopsy and microscopic examination (including special staining). FI was diagnosed if no progression of cancer was noted and no other complications occurred. Infection was present at the time of death in 116 patients (13.7%) and FI was the cause of death in 39 of them (4.6%). Nine patients died from fungal infection, eight from bacterial infection, seven from PCP and two from tuberculosis. In 13 cases the aetiology of infection found at autopsy was not determined. All FI patients received chemotherapy and corticosteroids, 16 of them also had radiotherapy on the tumour and mediastinum. Thirty-two out of 35 patients had leucopenia. The risk of death from infection was greater in patients above 60 years of age. Patients in bad performance status died of infection significantly earlier than others (P<0.05).

[Pulmonary thromboembolism as the main or secondary cause of death in patients treated for small cell lung cancer]

The aim of this study was to assess the frequency of pulmonary thromboembolism in small cell lung cancer (SCLC) patients (pts) treated in the Institute of Tuberculosis and Chest Diseases in the years 1980-1994. The second aim was to assess whether the occurrence of thromboembolism is connected with the progression of cancer. Pulmonary thromboembolism was recognised in 17 out of 845 pts (2.01%) treated for small cell lung cancer, that is in 2.01% of pts. The frequency of thromboembolism was 8% among patients in which autopsy was done. Pulmonary thromboembolism occurred in 7 pts during progressive disease but also in 9 with partial or complete regression of SCLC. The potential role of chemo- and radiotherapy in the development of thromboembolism in the last group was discussed.

[Myocardial infarction as a cause of death in patients treated for small cell lung cancer]

The aim of our study was to assess frequency of death from myocardial infarction in patients (pts) treated for small cell lung cancer (SCLC). 33 out of 845 patients treated for SCLC died from myocardial infarction. All patients were smokers. In 6 patients coexisted hypertension, in 2--diabetes and in 5--obesity. Eight patients have had cardiac disease in anamnesis. All patients were treated with one or more number of cardiotoxic drugs as DDP, VCR or VBL, E, MTX and ADR which are able to cause ischemic heart disease or myocardial infarction. Sixteen out of 33 patients have had radiotherapy of lung tumour. Death from myocardial infarction occurred from 0.5 up till 98.5 months from the beginning of start treatment. Eighteen men died from myocardial infarction in the first year of treatment. Risk of death from myocardial infarction was 15 times greater in men with SCLC than in men of the polish population at the same age and at the same time.

[Infection as a main or additional cause of death in patients treated for small cell lung cancer]

The aim of this study was to analyse the frequency of infection as a cause of death in small cell lung cancer (SCLC) patients. Our material consisted of 845 unselected SCLC patients, 246 women and 599 men, aged 29-78 years, treated between 1980-1994 in the Institute of Tuberculosis in Warsaw. 479 patients had limited and 366 extensive disease. 530 were in good (0-2) and 315 in bad (3-4) performance status. 784 patients died. Autopsy was done in 211 patients. Infection was regarded as a main cause of death in 39 patients (4.6%) and as a coexistent cause in 77 (9.1%). At the time of death from and/or with infection in 16 patients complete remission and in 27 partial remission of cancer was confirmed. The risk of death from and/or with infection was not related to the age and sex or to the performance status of patients and to extension of cancer. The risk of death from and/or with infection in the first 3 months of treatment was however greater for patients in bad performance status and with extensive disease and later (after 3rd months) for patients in good performance status and with limited disease.

[Predisposing factors for bronchiectasis--analysis of 69 patients treated in the years 1995-1999]

The aim of this study was to analyze the predisposing factors for bronchiectasis in 69 patients hospitalized in the 3rd Dept. of the Institute of TB and Lung Diseases in Warsaw in years 1995-1999. Bronchiectasis was diagnosed on the basis of the high resolution computed tomography (HRCT) scan. Among 69 patients at the age of 15-72 years there were 45 women (65%) and 24 men (35%). Fifty patients were nonsmokers. The most frequent predisposing factors of bronchiectasis in that group of patients were as follows: pneumonia (30.1%, in it recurrent pneumonia--19.3%, a single pneumonia--10.8%), sinobronchial syndrome (19.3%), pulmonary tuberculosis (12.1%), nontuberculous mycobacterial lung infections (7.2%), recurrent pneumonia and bronchitis in childhood (7.2%) and connective-tissue diseases (3.6%). Among other predisposing factors there were allergic bronchopulmonary aspergillosis, foreign body in bronchus, hypogammaglobulinemia and colitis ulcerosa.

[The cause of infection as the main or additional cause of death in patients treated for small cell lung cancer]

In 116 out of 845 patients treated for small cell lung cancer (SCLC) in the Institute of Tuberculosis and Chest Disease in Warsaw in the years 1980-1994 infection was the main or coexistent cause of death. In 4.1% infection was proved of bacterial origin and in further 6.5% of probable bacterial origin (in the later group cultures were negative or not done but fungal infection, pneumocystosis pneumonia and tuberculosis were excluded on autopsy). In 1.54% infection was of fungal origin, 1.2% patients died of Pneumocystis carinii pneumonia and 0.35% of tuberculosis. The majority of patients who died with and/or from infection had treatment-related leukopenia and 99 of them were treated with corticosteroids. Fungal infection, pneumocytosis and tuberculosis were found more frequently than bacterial infection in patients treated with cumulative dose of prednisone above 2000 mg. 33.62% patients had no symptoms or signs of infection. No connection was found between the absence of symptoms and treatment with steroids or the grade of leukopenia. In all cases infection was recognised very late, in 58 only at autopsy.

[The use of monoclonal antibodies in the detection of small cell lung cancer metastases in bone marrow]

Expression of a number of antigens associated with small cell lung cancer (SCLC) have been proposed as a marker of malignancy and the diagnostic tool for the staging procedures and important prognostic factor. Since the bone marrow (BM) was described as a frequent site for SCLC metastases, we have decided to assess clinical importance of cancer cells detection in BM, using immunofluorescence with MAC-1, MAC-31, NSE and anti-Fucosyl-GM1 (PF3) antibodies. The group of 32 patients with SCLC was assessed using our panel of antibodies. Control group consisted of 5 patients with other malignancies (3 patients with malignant lymphoma, 1 with chronic lymphocytic leukaemia and 1 with non-SCLC). The study revealed no correlation between the expression of SCLC markers in patients BM and the cancer treatment outcome measured as a response for treatment, time to progression, and survival time, and no significant difference was found between the patients and control group.

[The pattern of small cell lung carcinoma in autopsy (based on material of the Pathology Department, National Institute of Tuberculosis and Lung Diseases in Warsaw]

The aim of this study was to review autopsy findings in small cell lung carcinoma (SCLC) patients (pts)--in order to assess the distribution of the disease at the time of death and to analyse the pattern of SCLC in relation with different therapeutic modalities. The pattern of autopsy findings was assessed in 100 pts SCLC: 85 pts after treatment with chemotherapy, with or without chest and cranial irradiation; and 15 pts without any therapy. The primary tumours were present in 59% pts (50 of 85), the residual tumour deposits were diagnosed in 32% (27 of 85) pts. The significant difference in the rate of locoregional disease was found between pts given chemotherapy and pts after combined therapy. The tumours occurred significantly more frequently in pts after chemotherapy, than in pts after chemotherapy with irradiation on the chest (75% and 41% respectively, p = 0.03). The chest irradiation with chemotherapy caused less frequent occurrence of the residual tumours than chemotherapy alone (48% and 20%, respectively, p = 0.026). The rate of brain metastases was significantly higher in pts given chemotherapy than in pts treated with chemotherapy and chest irradiation or chemotherapy and curative brain irradiation (90%, 67% and 36% of 50 cases, respectively). Distant metastases were distributed in the same pattern in both studied groups. The distribution of metastases was not dependent on the disease extent at the time of diagnosis.

[Pneumocystis carinii infections in patients with neoplasms and AIDS--clinical-pathologic changes in the lungs]

Pneumocystis carinii (PC) has been documented as a cause of pneumonia in a broad range of immunocompromised patients. The presentation of disease will very based on the underlying predisposing condition but a confirmation depends upon the identification of organisms in a bronchial aspiration or lung biopsy specimen. This retrospective study based on autopsies of 15 patients (pts) with AIDS and 12 non AIDS pts with neoplastic diseases. Pneumocystis carinii pneumonia (PCP) was confirmed by histologic examination. The clinico-pathological analysis emphasizes a spectrum of morphologic variation of the disease in relation to the clinical course of a principal disease. A distinction was made between the microscopical diagnosis of PC infection in AIDS and non AIDS pts; the burden of organisms in infected AIDS pts appeared greater than that of neoplastic diseases (mostly with small cell lung carcinoma). Nonspecific features of diffuse alveolar damage associated with PC organisms were identified in 67% of non AIDS pts and 13% of AIDS pts. Various degree of interstitial fibrosis was more prominent in AIDS pts (67%) than in non AIDS pts. The high frequency of atypical changes in lung might be the result of various chemotherapeutic agents used in managing these pts or repeated pulmonary infections.

[Our experience in bronchiolitis obliterans organising pneumonia (BOOP): personal experience]

BOOP is a disease with characteristic histology features which can occur as a secondary lung reaction to the various toxic agents or as a primary idiopathic disease. Idiopathic form of BOOP is a rare disease and may be found in 6-7 patients of 100,000 hospital admissions. We described 3 patients with idiopathic BOOP confirmed by the histologic lung examination. The time from the beginning of symptoms till the microscopical diagnosis ranged from 6 to 12 months. At the beginning of the disease the patients had symptoms compatible with the respiratory infection. In one of the patients the clinical course of the disease had a progressive character. In two patients spontaneous regression of radiological lung lesions was observed. This regression was however only temporary in one of them. In two cases treated by steroids regression of lung lesions was noticed.

[Hepatic tuberculosis]

Tuberculosis of the liver can be the only manifestation of the disease or it may be a part of disseminated process. Three cases of liver tuberculosis were presented. In one of them the process was restricted to the liver and the diagnosis was made only at autopsy. In two other cases, tuberculosis of the liver was a part of disseminated process. In one of them the impairment of liver function improved after therapy and in another one, in spite of therapy, the patient died with signs of cardio-respiratory and hepatic insufficiency.
