Bone damage after chemotherapy for lymphoma: a real-world experience.

BACKGROUND: Despite recent improvements in survival due to advances in treatment, the quality of life of patients with lymphoma may be compromised by the long-term complications of chemotherapy and steroid therapy. Among these, a potentially relevant problem is bone loss and the development of fragility fractures. AIM: To provide further evidence of clinical or subclinical skeletal complications in correlation with biological variables and markers of bone disease in patients with complete response to therapy. METHOD: A cross-sectional observational study was conducted on subjects diagnosed with lymphoma with subsequent antineoplastic treatment, disease status after therapy defined as complete response disease for at least a year now. We performed: blood chemistry tests, imaging techniques and screening tools for the assessment of functional status and quality of life (SARC-F and mini-Osteoporosis Quality of Life). RESULTS: Approximately 50% of patients had osteoporosis, with a prevalence of vertebral fractures of 65.5%. In most patients, we found hypovitaminosis D and high levels of parathyroid hormone (PTH). Furthermore, a statistically significant association was observed between high PTH levels and previous lymphoma treatment. Finally, the Mini-Osteoporosis Quality of life (mini-OQLQ) questionnaire demonstrated a loss of quality of life as a consequence of the change in bone status. CONCLUSIONS: Patient treatment design for personalized chemotherapy would be desirable to reduce late effects on bone. Also, early prevention programs need to be applied before starting treatment. The most benefited subpopulations could be not only elderly but also young patients.

Anti-hepatitis A virus seroprevalence and seroconversion in a cohort of patients with chronic viral hepatitis.

BACKGROUND: Patients with chronic hepatitis C infected by hepatitis A virus have a substantial risk of fulminant hepatitis or death, while the course of hepatitis A virus is uncomplicated in most subjects with chronic hepatitis B. AIM: To evaluate the prevalence of anti-hepatitis A virus antibodies and the incidence of hepatitis A virus seroconversion in a nationwide sample of 530 patients with chronic hepatitis B and/or hepatitis C infection initially susceptible to this infection after a follow-up of some years. RESULTS: The overall anti-hepatitis A virus prevalence was 85.7%, with no difference between males and females. By the age of 50 years, almost all patients were found to have been exposed to hepatitis A virus. After a mean follow-up period of 76 months the overall anti-hepatitis A virus seroconversion rate in the 76 initially susceptible individuals was 1.2 per 100 person/years. However, it was 0.3 per 100 person/years in those hepatitis B surface antigen positive but 3.36 per 100 person/years in those anti-hepatitis C virus positive. None of the seroconverters was affected by a clinically evident disease or showed deterioration of underlying chronic liver disease. CONCLUSIONS: The present study shows that Italian patients >50 years of age with chronic liver disease have already been exposed to hepatitis A virus suggesting that anti-hepatitis A virus screening is not advisable in these subjects.

Randomised Trial of Two Different Daily Doses of Interferon-α versus Classical Therapy in Treatment-Naïve Patients with Chronic Hepatitis C.

OBJECTIVE: To evaluate the efficacy and tolerability of two different daily doses of interferon-α (lymphoblastoid-IFNα-N1, Wellferon®) [IFNα] for 2 months, followed by the same dose on alternate days for up to 1 year, versus administration on alternate days for 1 year. PATIENTS AND METHODS: A non-blind, randomised study of outpatients with chronic hepatitis C at five centres in Sicily, Italy. Ninety-seven consecutive treatment-naive patients [72 patients with hepatitis C virus (HCV) genotype 1b infection] with histological chronic hepatitis C were included in the study and randomised to receive IFNα subcutaneously: 5 million international units (MIU) daily for 2 months, followed by the same dose on alternate days for up to 1 year (n = 33, group A); 3 MIU for 2 months, followed by the same dose on alternate days for up to 1 year (32, group B); 5 MIU on alternate days for 12 months (32, group C). Adverse effects were monitored through interviews and by clinical and biochemical check-ups at 1-month intervals. RESULTS: There were no significant differences between the three groups with regard to age, gender, HCV genotype distribution, or severity of histological findings. Seven patients dropped out of the study because of severe adverse effects: three from group A, two from group B, and three from group C. Approximately 30% of the 97 patients, equally distributed between the three groups, had a 'flu-like syndrome of mild-to-moderate intensity. Dosage reduction of IFNα from 5 MIU to 3 MIU daily was necessary in two patients in group A during the first month of treatment. Overall, 88 patients completed treatment as scheduled. After the induction phase, HCV was eradicated from the bloodstream in 27 patients (81.8%) from group A versus 15 (46.9%) from group B (p < 0.001) and 15 (46.9%) from group C (p < 0.001). The switch to maintenance dosages caused some infection breakthroughs, with the result that at the end of treatment 16 patients in group A, 12 in group B and 14 in group C had undetectable serum levels of HCV-RNA. After treatment discontinuation, however, five patients in group A, four in group B and six in group C became HCV-RNA positive. Thus, at the end of follow-up, 11 patients in group A, eight in group B and eight in group C had a sustained virological response. CONCLUSION: The present study shows that induction therapy with 5 MIU of IFNα administered daily for 2 months is well tolerated and that the percentage of patients with viral eradication at the end of this phase is higher than the percentage obtained with traditional therapy. Unfortunately, this good initial response decreases as treatment continues with conventional therapy, thus nullifying the benefits of the induction phase.

Percutaneous liver biopsy: a safe outpatient procedure?

Following the discovery of hepatitis C virus, more liver biopsies (LB) than before are being performed to assess the severity of liver disease. In this study, following the recommendations for outpatient LB made by the Patient Care Committee of the American Gastroenterological Association, we assessed the feasibility and benefits of LB performed as an outpatient versus inpatient procedure over the last 7 years in our centre. The study included 1,581 patients consecutively examined in our institute; all LBs were performed by a single operator with a 16-gauge needle using the Menghini technique, and in all cases the puncture site was determined using prebiopsy ultrasound. Liver lesions were classified using grading and staging scores. Ultrasound-guided LB of focal lesions were excluded from this study. LB was performed on 1,318 outpatients and 263 hospitalized patients. The mean age of the hospitalized patients was higher than that of the outpatients (p < 0.0001). As major side effects, one death and one haemoperitoneum requiring blood transfusion were recorded in the hospitalized patients. As minor side effects, one haemorrhage occurred in the hospitalized patients, whereas a case of haemobilia and 2 cases of subcapsular haematoma were recorded in the outpatients. In both groups pain at the puncture site was the most frequent minor complication which easily resolved after non-steroid drug administration. Severe histological diagnoses, both in terms of grading and staging, were significantly associated with hospitalized patients. In conclusion, by carefully selecting patients and using prebiopsy ultrasound to assess the puncture site, outpatient LB can be safely performed in most cases; this procedure should be more widely used, because it has met with the favour of patients who are able to return home the same day and reduces public health care service costs.

Management of caudate lobe injury. Case report.

This article describes a case of abdominal trauma with laceration of the caudate lobe, avulsion of its short hepatic veins and tear of the inferior vena cava (IVC). Anatomic segmentectomy of I segment and direct suture of inferior cava vein was performed. On its arrival to the Emergency Department the patient was hemodynamically stable. Ultrasonography and CT scan demonstrated a fracture of I hepatic segment associated to a retroperitoneal haematoma. Because progressive anemia and unstable hemodynamic state, the patient was taken to the operating room for intervention. No postoperative complications due to surgery were reported. The patient left the hospital in XXII postoperative day, after normalization of clinical parameters.

Traumatic diaphragmatic injuries.

Traumatic diaphragmatic rupture is an uncommon but important problem in patients with multiple injuries. A retrospective analysis of 37 cases with diaphragmatic injuries, 34 of the left and 3 of the right hemidiaphragm, was carried out. Thirty-two patients were treated surgically during the acute phase and 5 after a variable delay post-trauma. Diagnostic problems are discussed, so also for comportance of a proper evaluation of chest films. Factors leading to a strong suspicion of diaphragmatic rupture in patients suffering from thoraco-addominal blunt trauma are emphasized in order to recognize diaphragmatic lesions. Finally, surgical treatment is considered. In most cases, laparotomy is the access route of choice, not only to achieve reduction of herniated viscera and repair of the diaphragmatic lesions, but also to treating the frequently associated intra-abdominal injuries. Whenever thoracotomy is required, it should always be performed via a separate incision.

Interferon-alpha alone versus interferon-alpha plus ribavirin in patients with chronic hepatitis C not responding to previous interferon-alpha treatment.

OBJECTIVE: To study the effects of monotherapy with leucocyte interferon-alpha (IFNalpha) versus IFNalpha + ribavirin in patients with chronic hepatitis C who were nonresponders to previous courses of recombinant or lymphoblastoid IFNalpha. DESIGN AND SETTING: This was a nonblind randomised study of outpatients at 3 centres in Palermo, Sicily, Italy. PATIENTS AND PARTICIPANTS: We recruited 72 patients (48 males, 24 females), mean age 48.8 +/- 6.6 years (range 31 to 63 years), with biopsy-proven chronic hepatitis C, predominantly genotype 1b. INTERVENTIONS: 24 patients (group A) received IFNalpha 6MU 3 times weekly for 6 months, and 48 patients (group B) received IFNalpha 6MU 3 times weekly + ribavirin 1200 mg/day for 6 months. ALT levels and adverse effects were monitored monthly, and hepatitis C virus (HCV) RNA levels were measured at study entry, at the end of treatment and after a 6-month follow-up. RESULTS: At baseline all patients were HCV-RNA positive and had ALT levels greater than twice normal. Mean post-treatment serum HCV-RNA levels were below baseline in group A, but the virus was eradicated in only 1 patient; 6 patients had normalised serum ALT levels. In group B at end of treatment, 12 patients were negative for HCV-RNA and serum ALT levels were normal in 18. At follow-up, all group A patients had elevated ALT levels and positive HCV-RNA. In group B, 3 patients were still negative for HCV-RNA and 4 had normal ALT. In 4 patients in group B, therapy was suspended because of anaemia, depression and decrease in neutrophil count; a flu-like syndrome was recorded with no frequency difference between groups. CONCLUSIONS: These results suggest that patients with chronic hepatitis C unresponsive to IFNalpha monotherapy could benefit from combination therapy with IFNalpha + ribavirin.

Intravenous natural beta-interferon in white patients with chronic hepatitis C who are nonresponders to alpha-interferon.

OBJECTIVES: alpha-Interferons (alpha-IFN) have been shown to be effective in the treatment of chronic viral C hepatitis, but their efficacy remains unsatisfactory. Recently natural beta-interferon (beta-IFN) administered by intravenous infusion has been used successfully. METHODS: To evaluate the efficacy and safety of intravenous beta-IFN administration we treated 20 patients with histologically proven chronic hepatitis C who were nonresponders to at least two previous courses of alpha-IFN treatment. All patients received 6 million units (MU) of natural human fibroblast beta-IFN by drip infusion, 6 times per wk for 8 wk and were followed up for 6 months after suspension of treatment. RESULTS: Five patients (25%) had response at the end of treatment; of these patients only one had sustained response. Patients who responded to therapy had lower, although not significantly, baseline levels of HCV RNA, compared with nonresponders. Whereas mean viral load decreased during therapy, only two patients were HCV RNA negative at the end of treatment, but none were at the end of the follow-up period. Genotype 1 was found in 17 cases, genotype 2 was found in one case, and a combination of genotypes 1b and 2a was found in the remaining two cases. Therapy was well tolerated and beta-IFN administration was neither interrupted nor its dosage reduced due to side effects in any of the patients. CONCLUSIONS: Our study shows that intravenous beta-IFN is well tolerated and that the modest results obtained may depend on the brevity of treatment. Consequently, further studies are needed to define the optimum dose, schedule, and duration of treatment to eradicate HCV infection.

[Factors predicting the response to alpha-interferon therapy in patients with chronic hepatitis C]. / Fattori predittivi di risposta al trattamento con alfa interferone in pazienti con epatopatia cronica anti-HCV positiva.

Objective of the study was to identify predictive factors of response to treatment with interferon in patients with anti-HCV positive chronic liver disease. 92 anti-HCV positive patients, 51 with chronic hepatitis and 41 with active cirrhosis, were treated for 12 months with recombinant alpha 2a interferon at a starting dose of 6 MU TIW/6 months, followed by 3 MU TIW/6 months. Patients were considered responders (RS) when they presented normal serum ALT values both at the end of treatment and after 6 months of follow-up; relapsers (RC) those with normal ALT values at the end of treatment but with increase during the 6 months of follow-up and non-responders (NR) patients who had no beneficial effect on ALT levels during treatment. 21 patients were RS, 11 RC and 60 cases NR. Univariate analysis of pre-treatment factors showed that response to interferon was associated with absence of cirrhosis and lower gamma-GT levels in RS than in RC. Multiple logistic regression of these variables showed that gamma-GT levels and absence of cirrhosis were the only independent factors associated with response to treatment. In conclusion, in our series of patients, only two factors were confirmed useful in predicting response to interferon treatment and it is concluded that they must always be evaluated before starting treatment with interferon which is not without side effects and may not have beneficial effect.

[Benign lesions of the thyroid. Clinical methodology++ and therapeutic management in our personal experience]. / Le affezioni benigne della tiroide. Metodologia clinica e tattica terapeutica nella nostra esperienza personale.

Thyroid benign nodules are common (90-95%). A personal series of 544 cases forms the basis for a discussion of modern diagnostic techniques, their value and limitations. At the present time, subtotal or near total thyroidectomy is preferred, also in benign thyroid disease. The perfect anatomical knowledge of the neck is of paramount importance to minimize the risk of complications, such as a superior or inferior laryngeal nerve injury and hypoparathyroidism. Temporary suclinic, clinic, definitive hypoparathyroidism was never observed. Relapse was observed in 20 hypothyreosic patients with hormonal therapy.

Serum Levels of Soluble IL-2R, CD4 and CD8 in Chronic Active HCV Positive Hepatitis.

The aim of the present study was to compare serum levels of soluble forms of interleukin-2 receptor, CD4 and CD8, released by lymphocytes during activation ofthe immune system, in patients with histologically verified chronic active hepatitis associated to hepatitis C virus infection, with those in healthy subjects. Significantly higher levels of soluble IL-2R and soluble CD8 were found in patients with chronic active hepatitis compared with controls. In contrast no difference was found for soluble CD4 values in the two groups. No correlations were found for both sIL-2R and sCD8 and these two molecules with other parameters of liver function. These results indicate that in these patients there is a general activation of the immune system, but the lack of correlation with parameters of liver function strengthens the suggestion that this activation does not play a role in the pathogenesis of chronic type C hepatitis.

[Campylobacter pylori (C. pylori): an occasional finding or a constant pathogenetic factor in peptic and inflammatory gastroduodenal pathology? Personal observations]. / Campylobacter pilori (C. pylori): un reperto occasionale o un fattore patogenetico costante nella patologia peptica ed infiammatoria gastroduodenale? Considerazioni personali.

The detection of CP in the mucosa of the gastric antrum had led to the supposition of this bacterium's potential pathogenetic role in the onset and continuation of peptic ulcer and/or inflammatory gastroduodenal disease. After reviewing the literature, the Authors report the incidence rate of the presence of C.P. in the mucosa of the gastric antrum in 110 symptomatic patients. Endoscopic examination revealed a negative diagnosis, or the presence of gastric and/or duodenal ulcer, or aspecific inflammatory disease. C.P. was detected using the quick urea test and histomorphological analysis after modified Giemsa staining on bioptic endoscopic specimens. C.P. were present in 86.6% of duodenal ulcers, 94.8% of gastro-duodenal inflammation, and 29.4% of endoscopical normal patients. These results confirm that C.P. should not be considered an occasional finding but almost a constant factors. The importance of performing the quick urea test during endoscopic examination is underlined, since if positive an appropriate therapeutic protocol can be started as soon as possible.
