ABSTRACT

PURPOSE: The primary objectives of this study were to evaluate safety, and efficacy of Transarterial Chemoembolization (TACE) using doxorubicin-loaded radiopaque microspheres (DC Bead LUMI™) for the treatment of early and intermediate stage Hepatocellular Carcinoma (HCC) not amenable for curative treatments. Distribution of the microspheres was correlated with results post embolization. MATERIALS AND METHODS: This was a prospective, single arm, open label study. The primary outcome measures were distribution of the radiopaque microspheres as showed by computerized tomography (CT) and local response measured by modified Response Evaluation Criteria (mRECIST) after Magnetic Resonance Imaging (MRI). Secondary measures were Time to Progression (TTP) and Overall Survival (OS). RESULTS: Fifty patients were enrolled over 36 months. Median age was 69.0 years; mean sum of target lesions diameters was 78.6 ± 36.8 mm. There were no Grade 4 or 5 adverse events (AEs). At 6 months Complete Response (CR) (18%), Partial Response (PR) (62%), Objective Response OR (80%) and Stable Disease (SD) (20%) were recorded. Before embolization, Diffusion Weighted Imaging (DWI) showed high signal (restricted diffusion). Post procedure, patients with dense deposition (< 5 mm distance of microsphere aggregations) showed 100% absence of enhancement and no restriction in 30.6%. Median TTP was 8.3 months. TTP for patients with CR was 13.3 months and 7.2 and 5.6 for PR and SD, respectively. At 6 and 36 months, survival was 94% and 34%, respectively. CONCLUSION: DC Bead LUMI™ is well tolerated and effective in early and intermediate stage HCC with maximal necrosis obtained in dense deposition in the target.

ABSTRACT

PURPOSE: To assess prospectively long-term results of doxorubicin-loaded HepaSphere 30-60 µm in consecutive patients with hepatocellular carcinoma (HCC) not amenable to curative treatments. PATIENTS AND METHODS: Single-center study from June 2011 to December 2015 in 151 patients treated with 75 mg of doxorubicin per HepaSphere vial. Baseline: Barcelona Clinic Liver Cancer BCLC A/B was 49.3%/50.7%, and median diameter 6.1 cm (mean 6.7 ± 2.0). Liver function, local response (mRECIST), liver time to progression (LTTP), progression-free survival (PFS), overall survival (OS) and adverse events (AEs) were recorded. RESULTS: Final analysis included 142 patients with median follow-up of 46.8 months (range 4-72) without grade 4/5 AEs, and 30-day mortality was 0%. Mean number of scheduled treatments was 2.6 (range 1-3) and on demand 3 (range 1-8). Complete response for single tumor ≤ 5 cm was 75.0% and 66.7% for Child A and Child B, while for > 5 cm was 28.6% and 11.8%, respectively. OS was 31.0 months (mean 33.3 ± 15.2; range 8-69), notably for BCLC A 41 months (mean 41.1 ± 15.3; range 13-69) and for BCLC B 26.0 (mean 26.0 ± 10.5; range 8-51). OS at 1, 3 and 5 years: 95.8%, 75.7% and 21.4% for BCLC A, and 94.4%, 36.1% and 2.7% for BCLC B. Median LTTP for BCLC A was 11 months (mean 11.9 ± 4.7; range 3-24) and 7.5 for BCLC B (mean 7.9 ± 2.9). Local response was significant for OS and LTTP (p < 0.0001), while size and lesion number affected LPFS and OS (p < 0.001). CONCLUSIONS: HepaSphere 30-60 µm loaded with doxorubicin provides a safe and effective treatment option for patients with HCC.

ABSTRACT

Chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are among the most serious health conditions affecting about 600 million people worldwide leading to a number of severe liver diseases. Due to the lack of warning signs or mild symptoms during the early stage of the infection, a molecular signature associated with disease progression would be useful. Based on our recent paper where candidate biomarkers were determined through topological and modularity analysis of protein interaction networks (PINs), this study was focused on the evaluation of MIF, TNFRSF1A, FAS and TMSB4X as diagnostic biomarkers in chronic HBV and HCV infections. The aim was to establish a molecular profile, by combining those markers, that would discriminate the different stages during the progression of chronic hepatitis. One hundred and fifteen patients infected with HBV or HCV categorized into three groups: non-cirrhotic, cirrhotic and with HCC, and 20 healthy subjects were enrolled in this study. Serum levels of the aforementioned factors were measured by ELISA. TNFRSF1A serum levels appeared statistically significantly increased in all patient groups compared to control group with a p-value of <0.05. Furthermore, the combination of TNFRSF1A and TMSB4X serum levels successfully classified 63, 47% of patients indicating an association with HBV and HCV infections. Thus, variations of serum levels of TNFRSF1A and TMSB4X could be associated with the different stages of the disease and may be utilized for further research. On the other hand, we found no contribution of MIF and FAS serum levels for successful classification of patients.

ABSTRACT

INTRODUCTION/AIM: Patients who present HBV reactivation during immunosuppressive treatment are prone to develop life threatening decompensation of the liver function, therefore prophylaxis and treatment are strongly recommended. So far there are no data regarding the role of tenofovir in this context. Therefore, the aim of our study was to describe our "real life" experience with the use of tenofovir (TDF) in patients who underwent immunosuppressive treatment. RESULTS: 38 patients with immunosuppression received antiviral treatment with tenofovir (25 patients as prophylaxis and 13 patients as treatment of HBV reactivation). In all 25 patients in whom prophylactic treatment with tenofovir was administered no HBV flare occurred during immunosuppression and the levels of serum HBV-DNA became or remained undetectable during the follow up period (mean follow up 17.2 months, range 6-54). One patient experienced HBsAg seroconversion. In the 13 patients who exhibited HBV reactivation TDF treatment resulted in complete biochemical and virological response within 6 months except two patients with high pretreatment HBV-DNA levels who became HBV-DNA negative at 9 months. No exacerbation of liver disease or liver related death has been observed. One patient who presented with decompensated cirrhosis during HBV reactivation returned into a compensated state after treatment. No side effects of tenofovir have been documented. CONCLUSION: Tenofovir seems to be highly effective and safe in the prophylaxis and rescue treatment of HBV reactivation in patients who receive immunosuppression therapy.

ABSTRACT

Sorafenib is considered the standard systemic therapy for hepatocellular carcinoma (HCC), in patients with well-preserved liver function (Child-Pugh A class) and advanced-stage HCC (BCLC-C) or in patients with HCC progressing after locoregional therapies, with a high grade of recommendation. The approval of sorafenib for this indication was grounded on the efficacy and the safety results reported by two international randomized, controlled trials, the SHARP and the Asia-Pacific studies. In addition, the efficacy and the safety of sorafenib in clinical practice are addressed by several field-practice experiences, including the multinational GIDEON study and the SOFIA study. Finally, further research on sorafenib is ongoing to optimize the use of this molecule. This review aims to provide an overview of the most relevant clinical data on the efficacy and the safety of sorafenib in patients with HCC.

ABSTRACT

Low oxygen tension exerts a significant effect on the replication of several DNA and RNA viruses in cultured cells. In vitro propagation of hepatitis C virus (HCV) has thus far been studied under atmospheric oxygen levels despite the fact that the liver tissue microenvironment is hypoxic. In this study, we investigated the efficiency of HCV production in actively dividing or differentiating human hepatoma cells cultured under low or atmospheric oxygen tensions. By using both HCV replicons and infection-based assays, low oxygen was found to enhance HCV RNA replication whereas virus entry and RNA translation were not affected. Hypoxia signaling pathway-focused DNA microarray and real-time quantitative reverse transcription-PCR (qRT-PCR) analyses revealed an upregulation of genes related to hypoxic stress, glycolytic metabolism, cell growth, and proliferation when cells were kept under low (3% [vol/vol]) oxygen tension, likely reflecting cell adaptation to anaerobic conditions. Interestingly, hypoxia-mediated enhancement of HCV replication correlated directly with the increase in anaerobic glycolysis and creatine kinase B (CKB) activity that leads to elevated ATP production. Surprisingly, activation of hypoxia-inducible factor alpha (HIF-α) was not involved in the elevation of HCV replication. Instead, a number of oncogenes known to be associated with glycolysis were upregulated and evidence that these oncogenes contribute to hypoxia-mediated enhancement of HCV replication was obtained. Finally, in liver biopsy specimens of HCV-infected patients, the levels of hypoxia and anaerobic metabolism markers correlated with HCV RNA levels. These results provide new insights into the impact of oxygen tension on the intricate HCV-host cell interaction.

ABSTRACT

The core region of the hepatitis C virus (HCV) genome possesses an overlapping ORF that has been shown to encode a protein, known as the alternate reading frame protein (ARFP), F or core+1. The biological role of this protein remains elusive, as it appears to be non-essential for virus replication. However, a number of independent studies have shown that the ARFP/F/core+1 protein elicits humoral and cellular immune responses in HCV-infected individuals and interacts with important cellular proteins. To assess the significance of the core+1 humoral response in HCV-infected patients, we examined the prevalence of anti-core+1 antibodies in sera from patients with hepatocellular carcinoma (HCC) in comparison with chronically HCV-infected individuals without HCC. We produced two HCV core+1 histidine-tagged recombinant proteins for genotypes 1a (aa 11-160) and 1b (aa 11-144), as well as a non-tagged highly purified recombinant core+1/S protein (aa 85-144) of HCV-1b. Using an in-house ELISA, we tested the prevalence of core+1 antibodies in 45 patients with HCC in comparison with 47 chronically HCV-infected patients without HCC and 77 negative-control sera. More than 50 % of the serum samples from HCC patients reacted with all core+1 antigens, whereas <26 % of the sera from the non-HCC HCV-infected individuals tested positive. No core+1-specific reactivity was detected in any of the control samples. In conclusion, the high occurrence of anti-core+1 antibodies in the serum of HCC patients suggests a role for the ARFP/F/core+1 protein in the pathogenesis of HCC.

ABSTRACT

OBJECTIVES: The aim of this prospective study was to examine the safety of anti-tumour necrosis factor (TNF) therapy in patients with rheumatic disease and hepatitis B virus (HBV) infection. METHODS: 14 patients with chronic HBV infection, 19 HBV-vaccinated patients and 19 patients with resolved HBV infection were included in the study. All HBV-infected patients received combination therapy with oral antivirals and anti-TNF agents. During treatment the levels of hepatitis B surface antibodies (anti-HBs) in HBV-vaccinated patients and of serum HBV DNA in patients with chronic or resolved HBV infection were monitored. RESULTS: No viral reactivation was observed in patients with resolved HBV infection while anti-HBs titres decreased during anti-TNF treatment in vaccinated patients, similarly to patients treated with methotrexate alone. None of the HBV-infected patients developed liver decompensation or a significant increase in alanine aminotransferase levels. One patient (7%) treated with lamivudine and etanercept showed viral reactivation due to the emergence of a lamivudine-resistant mutant strain. CONCLUSIONS: Anti-TNF agents represent a safe option for patients with chronic HBV infection when combined with antiviral therapy, as well as in patients previously exposed to HBV receiving no HBV prophylaxis. Resistant HBV strains may arise in patients with chronic hepatitis B, necessitating the initial use of anti-HBV agents with a low risk of resistance.

ABSTRACT

BACKGROUND: Survivin is a new member of the Inhibitor of apoptosis protein family that has a dual function as a mitotic regulator and apoptosis inhibitor. Survivin is prominently expressed in transformed cell lines and in many human cancers, including colorectal carcinoma. The aim of this study is to investigate the expression of survivin in colorectal carcinomas and its possible associations with clinicopathological parameters and patient survival. MATERIALS AND METHODS: Sections of formalin-fixed paraffin-embedded tissues from 77 colorectal carcinomas were immunohistochemistry stained for survivin. RESULTS: Survivin was mainly detected in the bottom of the glands of normal mucosa with mainly cytoplasmic localization. No survivin expression was found in infiltrating lymphocytes, fibroblasts, smooth muscle cells or neural tissue. Survivin staining was detected in 68/77 (88.3%) colorectal carcinomas. Survivin expression was found to be significantly associated with tumor differentiation (P = 0.02) but not with gender, age or Dukes stage. Survival did not differ according to survivin expression. CONCLUSION: Survivin was found in the majority of colorectal carcinomas, suggesting that its expression is an early event in colorectal carcinogenesis. Its expression is statistically significantly associated with tumor differentiation but not with patient survival.

ABSTRACT

The objective of this study was to investigate changes in the epidemiology of hepatitis B virus infection in the general population and selected groups of immigrants in the region of northeastern Greece over the last decade in relation to the introduction of hepatitis B vaccination programmes. Two population-based seroprevalence surveys were carried out during the years 1992-1994 and 1998-2006. In total, 25,105 individuals were tested for the presence of hepatitis B virus markers: HBsAg, anti-HBs and anti-HBc. Childhood/adolescence immunisation programmes began early in 1994 in selected groups of immigrants and were complemented by the national vaccination programme in 1998. Between 1992-1994 and 1998-2006, the HBsAg carrier rate declined from 5.4% [95% CI: 4.5-5.9] in adults (20-60 years old) and 1.9% [95% CI: 1.6-2.4] in children/adolescents (5-19 years old) of indigenous residents to 3.4% [95% CI: 2.9-3.8] and 0.6% [95% CI: 0.2-1.4] respectively (p<0.05). In spite of a decrease compared with 1992-1994, the percentage of HBsAg carriers was still relatively high in 1998-2006 among the Muslim religious minority group (8.2% [95% CI: 8.0-8.7] in adults and 2% [95% CI: 1.7-2.4] in children/adolescents) and in immigrants from the former Soviet Union (4.3% [95% CI: 3.6-4.7] in adults and 1.1% [95% CI: 0.8-2.4] in children/adolescents) (p<0.05 for both selected groups versus general population). The decline of the prevalence of HBsAg in the general population and selected groups of immigrants in northeastern Greece over the last decade supports the effectiveness of the ongoing immunisation programme although the information on the actual number of cases of acute HBV infection is not available.

ABSTRACT

Despite several studies, the association of glucose intolerance with chronic hepatitis B (CHB) or C (CHC) virus infection remains controversial. We evaluated the prevalence of glucose intolerance by oral glucose tolerance test (OGTT) in patients with CHB or CHC in comparison with matched controls. In total, 189 consecutive outpatients with CHB or CHC and 189 subjects individually matched for age, sex and body mass index (BMI) were included. OGTT was performed in all cases, except in known diabetics, and glucose intolerance was defined as impaired glucose tolerance (IGT), OGTT-diabetes or known diabetes. Most patients with abnormal OGTT had normal fasting glucose (IGT: 69.8%, OGTT-diabetes: 54.5%). Compared with their own controls, CHB patients had a higher prevalence of IGT (13.6% vs 2.5%, P = 0.018) and family history of diabetes (34.6% vs 16.0%, P = 0.011), while CHC patents had higher prevalence of glucose intolerance (37.0% vs 15.7%, Rho = 0.001), mostly because of more frequent IGT (21.3% vs 6.5%, Rho = 0.003). After age and BMI adjustment, patients with CHC compared with those with CHB had significantly higher prevalence of glucose intolerance (37.0% vs 29.6%, P = 0.037). In conclusion, increased prevalence of glucose intolerance is documented by OGTT both in CHC and CHB patients compared with age, sex and BMI matched controls. Glucose intolerance is more frequent in CHC than CHB patients, regardless of known risk factors. An OGTT might be necessary at the baseline work-up of CHB or CHC patients, as a normal fasting glucose value does not exclude IGT or OGTT-diabetes.

ABSTRACT

Liver transplantation remains an underdeveloped technique in Greece; currently there is no information on outcomes in Greek patients. In this study, data were provided on the outcomes of liver transplantation in 71 patients with a mean follow-up of 6 (0.1 to 16) years in our center. Mean age at transplantation was 46 +/- 13 years, while the main cause for transplantation was hepatitis B (16 patients, 23%) or C (six patients, 8%) virus. In the first posttransplantation year, three patients died, while 18 (25%) required at least one hospitalization with a median stay of 30 days. At the end of follow-up, 56 patients (79%) are alive. The leading cause of death was de novo malignancies (40%), appearing at a mean of 5.2 +/- 3.3 years. Late adverse effects of immunosuppressive therapy included hypertension (42%), hyperlipidemia (24%), chronic renal failure (21%), and diabetes mellitus (24%). With the exception of diabetes, all the above abnormalities were significantly associated with cyclosporine-based but not with tacrolimus-based immunosuppressive regimens. Relapse of primary disease in liver transplants occurred in 21 (29.6%) patients at a mean time of 1.5 +/- 1.4 years, of whom 67% were related to viral hepatitis. The quality of life (Karnofsky scale 1 to 6) was excellent in 64% of surviving patients, affordable in 21%, and poor in 15%. In conclusion, after 6 mean years, the majority of Greek liver transplant recipients conduct a normal life, although metabolic abnormalities are often observed. A national registry is needed to provide more solid evidence of outcomes.

ABSTRACT

BACKGROUND/AIMS: Severe involvement of central and/or peripheral nervous system is a rare complication of hepatitis C virus (HCV)-related cryoglobulinaemia. METHOD: Four patients with HCV-related type II/III cryoglobulinaemia (three males with genotype 1, one female with genotype 3) who presented with severe sensory-motor polyneuropathy, one with central nervous system involvement as well, were treated with pegylated IFNa-2b 1.5 microg/kg/week and ribavirin 10.6 mg/kg/daily for 48 weeks. Neurological evaluation involved detailed clinical motor and sensory scores/scales and neurophysiological studies before and after treatment. RESULTS/CONCLUSION: Three out of four patients had undetectable serum HCV-RNA, normal levels of aminotransferases and substantially lower or undetectable levels of cryoglobulins at the end of treatment and at 24 weeks follow-up period. Treatment was well tolerated and all patients exhibited significant improvement of neuropathy based on solid clinical and laboratory criteria that was associated with the virological response.

ABSTRACT

To evaluate hepatic expression of the nuclear proliferative marker Ki-67 and the p53 oncoprotein in hepatitis B virus (HBV)/HCV cirrhosis in relation to dysplastic liver cell changes and hepatocellular carcinoma (HCC). We studied needle liver biopsies from 107 patients with cirrhosis and no HCC (52 HBV, 55 HCV) who had been assessed for protocol studies, and 57 cirrhotic patients with HCC (40 HBV, 17 HCV). We evaluated small and large cell dysplastic changes along with the expression of Ki-67 and p53 by immunohistochemistry. The labelling index (LI) was defined as the proportion (%) of positive-stained nuclei of the 500 measured. Large and small cell dysplastic changes were observed in 12 and 9% of specimens respectively. Only small cell changes were associated with Ki-67 expression. Ki-67 LI was 5.50 +/- 5.7 in cirrhosis (13.90 +/- 3.84 in those with small cell dysplastic changes vs 4.64 +/- 4.98 in those without, P < 0.01), 10.2 +/- 5.95 in cirrhosis with HCC (P < 0.05) and 18.56 +/- 10 in HCC (P < 0.01). Neither the presence of small cell dysplastic changes nor the expression of Ki-67 was related to severity or aetiology of cirrhosis. Expression of p53 was observed in 30% of the non-tumorous and in 53% of the neoplastic tissue obtained from patients with HCC, with no differences between HCV and HBV. Ki-67 and p53 expression was associated with the tumour grade (P < 0.001). Our observations clearly demonstrate the association between the proliferation activity and the morphological changes in the cirrhotic liver from the non-dysplastic to dysplastic lesion to HCC. They also support the hypothesis that p53 alterations are a rather late event in carcinogenesis and related to HCC grade. And finally, they suggest that the final steps of hepatocarcinogenesis are common and independent of the aetiology of the chronic viral infection.

ABSTRACT

SUMMARY: The aim of this study was to investigate the relative frequency of hepatitis C virus (HCV) genotypes in Greek patients with chronic infection as well as possible secular changes in their distribution in relation to modes of transmission, age and time at acquisition of the infection and other variables. We evaluated 434 unselected patients, 241 males and 193 females with a median age of 46.2 years (18-75), with chronic HCV infection presenting during the period 1996-2000. HCV infection was confirmed by the detection of HCV-RNA by polymerase chain reaction (PCR), while HCV genotyping was performed by the Inno-LiPA assay. Liver biopsies were evaluated according to Ishak's scoring system. Of 434 patients, 167 had a history of blood transfusion [post-transfusion hepatitis (PTH)], 80 were i.v. drug users and in 187 the route of infection remained unknown. The overall distribution of HCV genotypes 1, 2, 3 and 4 was 47, 8.3, 27 and 15.2%, respectively. Genotype 3 was common in younger adults and i.v. drug users, whereas genotype 1 predominated in older people and PTH patients (P < 0.001 for both). Infection acquired before 1981 (group A) was related to transfusion and genotype 1, while after 1981 (group B) with i.v. drug use and genotype 3 (P < 0.01). Biopsy was available in 369 (85%) patients, of whom 22.5% had cirrhosis; 29.8% in group A and 9.9% in group B. In a multivariate analysis, cirrhosis was strongly associated with the duration of infection (P = 0.013). Our study revealed a change of HCV genotype distribution in the last 20 years among Greek patients with chronic HCV infection as a result of epidemiological changes in HCV transmission. The presence of cirrhosis was associated only with the duration of infection. These observations have impact both on prevention and treatment.

ABSTRACT

The aim of the study was to assess the long-term outcome of chronic hepatitis B surface antigen (HBsAg) carriers in the general population in North Greece (Thrace), an area with an intermediate endemicity. This was a part of the Interreg I-II EC project. Two hundred sixty three chronic HBsAg+ carriers, median age 34 years (20-65), were evaluated prospectively for a median follow-up of 5 years (2-12). Hepatitis B virus (HBV) markers and ALT were examined every 6 months and serum HBV-DNA every 12 months. Liver biopsy was undertaken at presentation and every 2-4 years. Fourteen of 263 (5.3%) subjects were HBeAg+ and 249/263 (94.7%) HBeAg(-)/anti-HBe+ of whom 48 (19.3%) had elevated ALT, and HBV-DNA levels ranging from 1.4 x 10(5)-4 x 10(7) copies/ml. Inactive carriers (98/195 (50.3%)) had detectable HBV-DNA (median 2.6 x 10(3) range 0.042 x 10(4)-1.9 x 10(4) copies/ml); 4/195 (2%) exhibited HBV reactivation during the observation period (all had HBV-DNA >10(4) copies/ml at presentation). Patients (7/14 (50%) HBeAg+) developed anti-HBe+, annual rate 10%. Subjects (16/195 (8%)) lost HBsAg, all were inactive carriers; 10 developed anti-HBs (annual rate 1%). Liver biopsy was normal or with minimal changes in 92/95 (97%) inactive carriers and remained so at 4 years follow-up. In contrast, 4/48 (8.3%) HBeAg(-)/anti-HBe+ patients with active disease had deterioration of liver histology. In this cohort study: (a) the annual seroconversion rate was 1% for the HBsAg and 10% for the HBeAg, (b) 23.6% of the HBsAg+ carriers had active liver disease and 39% moderate fibrosis at presentation of whom a small proportion deteriorated over the observation period, (c) HBsAg carriers with HBV-DNA level <10(4) copies/ml had persistently normal ALT and unchanged liver histology over the follow-up period of up to 12 years.

ABSTRACT

Chronic infection with hepatitis B virus (HBV) has been reported in two-thirds of cases of hepatocellular carcinoma (HCC) in Greece from 1973 to 1995, while chronic hepatitis C virus (HCV) infection in 10% of them. We studied the roles of HBV and HCV in HCC in Greece between 1996 and 2000 compared with the past, and possible differences in clinical and laboratory characteristics of HBV- and HCV-related HCC. Complete clinical and laboratory data from 306 patients with HCC, diagnosed from January 1996 to December 2000, were analyzed. Chronic HBV and HCV infection were detected in 52.3 and 21.6% of the patients, respectively. The ratio of HBV- to HCV-related HCC was 2.42. Compared with the data prior to 1996, there was a 101.8% increase in the relative frequency of HCV (P < 0.0001) and an 11.8% decrease in that of HBV (P = 0.033), with a -56.3% change in the ratio of HBV- to HCV-related HCC cases. Statistically significant differences in the male/female ratio, median age and frequency of multifocal lesions were found in HBV- vs HCV-related HCC. Although HBV still represents the major aetiological factor of HCC in Greece, its role has significantly decreased in the last 5 years, while a more significant increase has occurred in HCV-related HCC. The two aetiological types of HCC differ in Greece in demographic, epidemiological and other features.

ABSTRACT

A 50-year-old man with no medical history was admitted because of progressive respiratory distress, aseptic meningitis, disseminated intravascular coagulation, cholestatic hepatitis, and renal failure. Mycoplasma pneumoniae infection was confirmed serologically. The patient was treated with erythromycin and showed a favorable recovery. Although M. pneumoniae infection is usually a benign, self-limited acute respiratory disease, on rare occasions it can manifest itself with a fulminant course and multi-organ involvement, even in normal healthy individuals.
