Background/Aim: Primary mediastinal large Bcell lymphoma (PMLBCL) is an aggressive B-cell non- Hodgkin lymphoma (NHL), whose prognosis has greatly improved since the incorporation of the anti-CD20 monoclonal antibody rituximab into current therapeutic regimens. Evidence, however, on the optimal time interval between consecutive chemoimmunotherapy (CIT) cycles is still scarce. This study aimed to evaluate the efficacy outcomes of the more commonly administered 3-weekly regimens to the biweekly ones in a PMLBCL patients' population, who were mostly treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone every 21 days (R-CHOP-21) or R-CHOP-14. Patients and Methods: We retrospectively studied our cohort of consecutively treated PMLBCL patients, focusing on their treatment density, in order to determine possible differences in treatment outcomes. Results: CIT, in the form of both RCHOP- 21 as well as R-CHOP-14 (or similar regimens), is highly active in PMLBCL, with low rates of early treatment failure. In our cohort of patients, R-CHOP-14 did not result in a meaningful improvement of freedom from progression (FFP) or overall survival (OS). Conclusion: Both R-CHOP- 14 and R-CHOP-21 are probably equally effective in PMLBCL, yet further, prospective, randomized studies are warranted to clarify whether dose-dense regimens can be associated with better disease control and long-term results. © 2022 International Institute of Anticancer Research.

Red blood cell transfusions (RBCT) remain the cornerstone of supportive care in lower-risk myelodysplastic syndrome (LRMDS) [1]. Transfusion dependency in LRMDS patients is associated with inferior outcomes, mainly attributed to severe bone marrow failure [2]. However, iron toxicity, due to frequent RBCT or ineffective erythropoiesis, may be an additional negative prognostic factor [3,4,5,6]. Recently, much progress has been made in unraveling the iron metabolism. The peptide hormone hepcidin is the key regulator by inhibiting iron uptake through degradation of ferroportin, a cellular iron exporter [7]. Erythroferrone and GDF15, produced by erythroblasts, inhibit hepcidin production, which leads to increased uptake and cellular release of iron for the purpose of erythropoiesis [8]. The pathophysiology of iron metabolism in MDS is still not completely understood. Exceedingly high reactive oxygen species (ROS) levels are associated with iron toxicity, disease development, and progression in MDS patients [9,10,11,12]. Malondialdehyde (MDA), resulting from lipid peroxidation of polyunsaturated fatty acids, is a biomarker of oxidative stress [10, 12]. Currently, little is known about the prognostic impact of ROS in MDS patients. The aim of this study is twofold: (1) describe iron and oxidative stress parameters over time in LRMDS patients and (2) to assess their effect on overall and progression-free survival. The EUMDS registry prospectively collects observational data on newly diagnosed LRMDS patients from 148 centers in 16 countries in Europe and Israel as of January 2008. All patients provided informed consent. Clinical data were collected at baseline and at each six-monthly follow-up visit. Serum samples were collected prospectively at each visit from 256 patients included in six participating countries. Conventional iron parameters were measured with routine assays. We additionally analyzed hepcidin, growth differentiation factor 15 (GDF15), soluble transferrin receptor (sTfR), non-transferrin bound iron (NTBI), labile plasma iron (LPI), and MDA. Subjects were prospectively followed until death, loss to follow-up, or withdrawal of consent. All iron parameters were measured centrally at the department of Laboratory Medicine of the Radboudumc, Nijmegen, The Netherlands. Serum samples were collected just prior to transfusion in transfusion-dependent patients and stored at −80 °C. Details on the assays and reference ranges of hepcidin, GDF15, sTfR, NTBI, LPI, and MDA are provided in the supplement. The Spearman rank test was used to evaluate correlations between iron parameters. We stratified the results by transfusion dependency per visit and the presence of ring sideroblasts. When evaluating temporal changes in iron parameters, with linear quantile mixed models, we excluded patients from the timepoint they received iron chelation therapy. Overall survival (OS) was defined as the time from MDS diagnosis to death or, in case of progression-free survival, to date of progression or death; patients still alive at the end of follow-up were censored. Time-dependent Kaplan–Meier curves and cox proportional hazards models were used. In total, 256 consecutive patients, were included in this study. Over five six-monthly visits, 1040 samples were collected. Table 1 describes the patient characteristics. Most patients without ring sideroblasts were transfusion-independent at diagnosis (nonRS-TI; 55.9%), 18.8% with ring sideroblasts were transfusion-independent (RS-TI), 18.4% without ring sideroblasts were transfusion-dependent (nonRS-TD), and 7% with ring sideroblasts were transfusion-dependent patients (RS-TD). The median follow-up time was 6.6 years (95% CI 5.9–7.0). LPI was positively correlated with transferrin saturation (TSAT) (r = 0.15, p < 0.001, Fig. S1). LPI values increased exponentially at TSAT values above 80%. This effect was most pronounced in the transfusion-dependent groups, but also observed in the RS-TI group. MDA was weakly correlated with NTBI (r = 0.09, p = 0.069) and negatively correlated with hemoglobin level (r = −0.1, p = 0.033). GDF15 and hepcidin were negatively correlated in the RS-TI and nonRS-TD group and significantly negatively correlated in the RS-TD group (r = −0.34, p = 0.007, Fig. S2). Serum ferritin levels were elevated in all subgroups with a mean value of 858 µg/L at visit 5. The highest serum ferritin levels were observed in the RS-TD group (mean value at visit 5: 2092 µg/L, Table S1). Serum ferritin increased significantly per visit in the RS-TD group (beta 454.46 µg/L; 95% CI 334.65–574.27), but not in the other groups (Table S2). All subgroups, except for the nonRS-TI, had elevated TSAT levels. TSAT levels were most markedly increased in the RS-TD group with a mean TSAT of 88% at visit 5 (Table S1). In both transfusion-dependent groups the median increase per visit was significant (Table S2). LPI was elevated in the RS-TD group exclusively with a mean value of 0.59 µmol/L at visit 5 (Table S1). NTBI was elevated in all subgroups, with the highest values in the RS-TD group (Table S1). The increase in median NTBI level was significant in both transfusion-dependent groups (Table S2). Hepcidin levels were markedly elevated in the nonRS-TD group. Interestingly, hepcidin levels were lower in the RS-TD group, probably reflecting ineffective erythropoiesis, likewise supported by lower hepcidin/ferritin ratios in RS groups (Table S1). Median hepcidin levels increased over time in the transfusion-dependent subgroups only (Table S2). GDF15 levels, analyzed in the light of its potential role in hepcidin suppression, were increased in all subgroups (Table S1). The RS subgroups had higher GDF15 levels compared to the nonRS groups, reflecting increased erythropoiesis. Mean sTfR levels were within the reference range in all subgroups except for the RS-TI group, which showed elevated levels, reflecting...

End-of-treatment (EoT) PET/CT is used as a guide to omit radiotherapy (RT) patients with primary mediastinal large B-cell lymphoma (PMBCL). We present the mature and extended results of a retrospective study evaluating the prognostic significance of EoT-PET/CT after adequate response to R-CHOP. Among 231 consecutive PMLBCL patients, 182 underwent EoT-PET/CT and were evaluated according to the Deauville 5-point scale (D5PS) criteria. Freedom from progression (FFP) was measured from the time of PET/CT examination. Among 182 patients, 72 (40%) had D5PS score 1 (D5PSS-1), 33 (18%) had 2, 28 (15%) had 3, 29 (16%) had 4, and 20 (11%) had 5. The 5-year FFP was 97, 94, 92, 82, and 44% for D5PSS-1, D5PSS-2, D5PSS-3, D5PSS-4, and D5PSS-5, respectively. Among 105 patients with unequivocally negative PET/CT (D5PSS-1/D5PSS-2), 49 (47%) received RT (median dose 3420 cGy) and 56 (53%) did not with relapses in 0/49 vs. 4/56 patients (2 mediastinum and 2 isolated CNS relapses).The 5-year FFP for those who received RT or not was 100% versus 96%, when isolated CNS relapses were censored (p = 0.159). Among D5PSS-3 patients (27/28 irradiated-median dose 3600 cGy), the 5-year FFP was 92%. The 5-year FFP for D5PSS-4 and D5PSS-5 was 82 and 44%; 44/49 patients received RT (median dose 4000 and 4400 cGy for D5PSS-4 and D5PSS-5). Our study supports the omission of RT in a sizeable fraction of PET/CT-negative patients and definitely discourages salvage chemotherapy and ASCT in patients with PMLBCL who conventionally respond to R-CHOP, solely based on PET/CT positivity in the absence of documented progressive or multifocal disease. The persistence of positive PET/CT with D5PSS < 5 after consolidative RT should not trigger the initiation of further salvage chemotherapy in the absence of conventionally defined PD. © 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH, DE part of Springer Nature.

This retrospective study aimed to describe the Hellenic experience on the use of brentuximab vedotin (BV) in relapsed/refractory (R/R) Hodgkin lymphoma (HL) given within its indication. From June 2011 to April 2015, ninety-five patients with R/R HL, who received BV in 20 centers from Greece, were analyzed. Their median age was 33 years, and 62% were males. Sixty-seven patients received BV after autologous stem cell transplantation failure, whereas 28 patients were treated with BV without a prior autologous stem cell transplantation, due to advanced age/comorbidities or chemorefractory disease. The median number of prior treatments was 4 and 44% of the patients were refractory to their most recent therapy. The median number of BV cycles was 8 (range, 2-16), and the median time to best response was the fourth cycle. Fifty-seven patients achieved an objective response: twenty-two (23%), a complete response (CR), and 35 patients (37%), a partial, for an overall response rate of 60%. Twelve patients (13%) had stable disease, and the remaining twenty-six (27%) had progressive disease as their best response. At a median follow-up of 11.5 months, median progression-free survival and overall survival were 8 and 26.5 months, respectively. Multivariate analysis showed that chemosensitivity to treatment administered before BV was associated with a significantly increased probability of achieving response to BV (P =.005). Bulky disease (P =.01) and response to BV (P

Lung cancer is one of the most common malignancies in the world and one of the leading causes of death from cancer. In the search for molecules that may be involved in lung tumor induction and progression, the receptor of advanced glycation end products (RAGE) comes across as a critical regulator of lung physiology. RAGE is a multiligand receptor that presents a differential expression pattern in lung epithelial cells compared to other cell types being gradually increased from fetal to birth and adult life. Under stress conditions, RAGE expression and activation are rapidly elevated resulting in chronic inflammation, which, in turn, in many instances, promotes epithelial cell malignant transformation. RAGE overexpression in normal lung alveolar type I epithelial cells is followed by rapid downregulation upon malignant transformation, being associated with increased aggressiveness. This is a striking paradox, since in every other cell type the pattern of RAGE expression follows the opposite direction, suggesting the involvement of RAGE in the well-functioning of lung cells. Additionally, RAGE has been attributed with the role of adhesion molecule, since it can stabilize mature alveolar epithelial cells to their substrate (basal lamina) by interacting electrostatically with other molecules. However, the reduction of RAGE observed in lung tumorigenesis interrupts cell-to-cell and cell-to-substrate communication, which is a critical step for cancer cell induction, progression and migration. This review addresses the differential properties of RAGE in lung physiology and carcinogenesis, providing evidence of therapeutic possibilities.

Endocrine complications due to haemosiderosis are present in a significant number of patients with beta-thalassemia major (BTM) worldwide and often become barriers in their desire for parenthood. Thus, although spontaneous fertility can occur, the majority of females with BTM is infertile due to hypogonadotropic hypogonadism (HH) and need assisted reproductive techniques. Infertility in these women seems to be attributed to iron deposition and iron-induced oxidative stress (OS) in various endocrine organs, such as hypothalamus, pituitary, and female reproductive system, but also through the iron effect on other organs, such as liver and pancreas, contributing to the impaired metabolism of hormones and serum antioxidants. Nevertheless, the gonadal function of these patients is usually intact and fertility is usually retrievable. Meanwhile, a significant prooxidants/antioxidants imbalance with subsequent increased (OS) exists in patients with BTM, which is mainly caused by tissue injury due to overproduction of free radicals by secondary iron overload, but also due to alteration in serum trace elements and antioxidant enzymes. Not only using the appropriate antioxidants, essential trace elements, and minerals, but also regulating the advanced glycation end products, could probably reduce the extent of oxidative damage and related complications and retrieve BTM women's infertility. © 2013 Paraskevi Roussou et al.

More aggressive treatment approaches (methotrexate, cytarabine, cyclophosphamide, vincristine, prednisone, and bleomycin [the MACOP-B regimen] or consolidation with high-dose therapy and autologous stem cell transplantation) have been considered to be superior to cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) in patients with primary mediastinal large B-cell lymphoma (PMLBCL). Rituximab-CHOP (R-CHOP) is the standard of care for diffuse large B-cell lymphoma, whereas efficacy in PMLBCL has not been adequately confirmed. Patient and Methods. Seventy-six consecutive PMLBCL patients who received R-CHOP with or without radiotherapy (RT) were compared with 45 consecutive historical controls treated with CHOP with or without RT. Baseline characteristics of the two groups were balanced. Results. The rate of early treatment failure was much lower with R-CHOP with or without RT (9% versus 30%; p =.004). The 5-year freedom from progression rate after R-CHOP with or without RT was 81%, versus 48% for CHOP with or without RT (p < .0001). The 5-year event-free survival rates were 80% and 47% (p < .0001) and the 5-year overall and lymphoma-specific survival rates were 89% and 69% (p = .003) and 91% and 69% (p = .001), respectively, with only seven of 76 lymphoma-related deaths. Among R-CHOP responders, 52 of 68 received RT. Conclusions. Based on these results, most patients with PMLBCL appear to be cured by R-CHOP in 21-day cycles with or without RT, which could be the current standard of care. Therefore, the need for more aggressive treatment strategies is questionable unless high-risk patients are adequately defined. Further studies are required to establish the precise role of RT. ©AlphaMed Press.

Purpose: A prospective study was conducted in order to investigate the serologic evidence of Mycoplasma pneumoniae infection in Greek hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Furthermore, we have assessed the frequency of a number of variables in the group of patients with a serological diagnosis of an acute M. pneumoniae infection compared to patients in whom M. pneumoniae infection was not documented. Materials/Methods: One hundred patients with AECOPD were enrolled in a 29-month study period. Serum IgG, IgA and IgM M. pneumoniae antibody titers were determined during the first day of their hospitalization and 30 days after enrolment, using a commercial ELISA. Results: Nine patients (9%) had serological evidence of an acute M. pneumoniae infection. Acute infection was mainly documented by IgA antibody titer changes. It was mainly attributed to a reinfection rather than a primary infection. Patients with serological evidence of an acute M. pneumoniae infection had a higher heart rate (99+/-12 versus 88+/-14 beats/minute, p=0.02) and a higher hematocrit value (47+/-4.5% versus 40.4+/-6.2%, p=0.004) at admission than patients without a serological diagnosis for this pathogen. Conclusions: Serologic evidence of M. pneumoniae infection is rather common in Greek hospitalized patients with AECOPD. The determination of all three antibody classes was necessary in order to obtain an optimal level of serodiagnosis. No differences were found in the majority of characteristics of patients with and without serological evidence for this pathogen. The clinical utility of these results should be further clarified in future studies.

The recently proposed, ISSWM staging system for symptomatic patients with WM was based on patients treated with alkylating agents and nucleoside analogs and has not been externally validated nor has been validated for cause-specific survival (CSS). We independently validated ISSWM both for overall survival (OS) and for CSS and assessed whether addition of elevated serum LDH may add to the strength of ISSWM in 335 patients treated upfront mainly with alkylating agents (43%), and rituximab-based therapies (47%). ISSWM could discriminate three groups with significantly different OS and CSS (p< 0.01 for both). High serum LDH was predictive of shorter OS and CSS (p< 0.01). The combination of high risk according to ISSWM and elevated serum LDH identified a subset of patients for whom innovative treatment approaches are needed. © 2010 Elsevier Ltd.

Pure infradiaphragmatic Hodgkin's lymphoma (HL) is a rare disease. The prognostic impact of a purely infradiaphragmatic localization of this lymphoma is controversial. We aimed to evaluate the baseline clinicopathologic features, prognostic factors and outcome of a large series of consecutive patients with pure infradiaphragmatic HL.We analyzed 131 patients with clinical stage I/II infradiaphragmatic HL treated with ABVD or equivalent regimens with or without radiotherapy, and compared 54 of them with 444 patients with pure supradiaphragmatic disease, who were treated at the same center.Older age, clinical stage II (borderline), involvement ofor =3 sites, lymphocyte predominant histology, elevated serum beta2-microglobulin and higher International Prognostic Score were more frequent in patients with infradiaphragmatic disease than in those with supradiaphragmatic disease, while nodular sclerosis was less frequent. The complete remission rate was 100%, 97% and 82% for stages I, IIA and IIB, respectively. Only B-symptoms independently predicted for inferior failure-free survival, while inferior overall survival was independently associated with the involvement ofor =3 sites. At 10 years failure-free survival was 82+/-6% (vs. 85+/-2% for patients with supradiaphragmatic disease, p=0.45), overall survival was 74+/-8% (vs. 91+/-2%, p=0.0006), and disease-specific survival 87+/-5% (vs. 94+/-1%, p=0.04). In multivariate analysis the differences between infradiaphragmatic and supradiaphragmatic disease were obscured by older age and B-symptoms.Pure infradiaphragmatic HL presents with distinct clinicopathologic characteristics. The previously reported poorer outcome may be explained by the unfavorable profile of the patients rather than the infradiaphragmatic presentation per se. Patients with stage IIB disease should probably be classified as having advanced HL because of the unacceptable rate of primary refractory disease.

We developed a clinical prediction rule for bone marrow involvement (BMI) in Hodgkin lymphoma based on 826 patients and validated it in 654 additional patients. Independent prognostic factors for BMI were x1, B symptoms; x2, stage III/IV prior to bone marrow biopsy; x3, anemia; x4, leukocytes fewer than 6 × 109/L; x5, age 35 years or older; and x6, iliac/inguinal involvement. Each factor was graded as xi = 1, if present, or xi = 0, if absent. A simplified score Zs = 8x1 + 6x2 + 5x3 + 5x4 + 3x5 + 3x6 - 8 was assigned to each patient. The sensitivity, specificity, and positive and negative predictive value of this prediction rule was 97.8%, 51.5%, 10.6%, and 99.8%, respectively. In the validation group, they were 98.1%, 40.3%, 12.7%, and 99.6%. According to Zs value, 3 risk groups for BMI were defined: low risk (Zs < 0, 44% of patients, 0.3% risk), standard risk (Zs, 0-9; 37% of patients; 4.2% risk), and high risk (Zs ≥ 10, 20% of patients, 25.5% risk). Patients with low risk (stage IA/IIA without anemia and leukopenia; stage IA/IIA, younger than 35 years, with either anemia or leukopenia but no inguinal/iliac involvement; and stage IIIA/IVA without any of these 4 risk factors) do not need bone marrow (BM) biopsy. Patients with standard risk should be staged with unilateral biopsy, but patients with high risk may benefit from bilateral biopsy. © 2005 by The American Society of Hematology.

Interleukin-18 (IL-18) plays a role in the host’s response to tumours and angiogenesis. We determined serum levels of IL-18, vascular endothelial growth factor (VEGF), angiogenin (ANG), tumor necrosis factor (TNF-alpha) and CRP in 65 newly diagnosed myeloma patients. IL-18, VEGF, angiogenin, TNF-alpha and CRP were significantly higher at stage III in comparison to stages 11 and I. These cytokines (measured in 27 patients) significantly decreased after treatment. In survival analysis, higher levels of IL-18 were associated with a poorer prognosis. We conclude that increased serum IL-18 in myeloma patients correlates with advanced disease, increased levels of angiogenic cytokines and worse survival. (C) 2003 Elsevier Ltd. All rights reserved.

Objective: To investigate hypothalamic-pituitary-adrenal axis function in patients requiring mechanical ventilation for traumatic brain injury and to assess the relation of hypothalamic-pituitary-adrenal axis abnormalities with vasopressor dependence and peripheral cytokine levels. Design: Prospective study. Setting: General intensive care unit in a university teaching hospital. Patients: Forty patients (33 men and 7 women) with moderate to severe traumatic brain injury (mean age, 37 +/- 16 yrs) were studied the day after termination of mechanical ventilation (7-60 days after trauma). Interventions: First, a morning blood sample was obtained to measure baseline cortisol, corticotropin, interleukin-6, and tumor necrosis factor alpha. Subsequently, 1 mug of synthetic corticotropin was injected intravenously, and 30 mins later, a second blood sample was drawn to determine stimulated plasma cortisol. Based on data derived from healthy volunteers, patients having stimulated cortisol levels

Hepatocyte growth factor (HGF) has been shown to be involved in angiogenesis, epithelial cell proliferation, and osteoclast activation. HGF and its receptor are expressed on myeloma cell lines and could be involved in the pathogenesis of bone destruction in multiple myeloma (MM). The aim of this study was to examine serum levels of HGF in untreated MM patients and its correlation with bone turnover indices and markers of disease activity. Forty-seven newly diagnosed MM patients and 25 controls were included: 12 patients were of stage I, 13 of stage II, and 22 of stage III (Durie-Salmon classification). Bone lesions were scored from 0 to 3, according to X-ray findings. Serum osteocalcin (OC), interleukin-6 (IL-6), TNF-alpha, beta(2)-microglobulin (beta(2)M), CRIP, calcium, and 24-hr urine N-telopeptide cross-links of collagen breakdown (NTx) were determined. HGF levels were significantly higher at stage III compared to stages II and I (medians: 1,990.4 vs. 1,743.8 and 1,432.4 pg/mL, respectively, P < 0.05). Similarly, NTx, IL-6, TNF-alpha, CRIP, beta(2)M, and calcium increased significantly with advancing stage (P < 0.01). OC was higher at stage I in comparison to stages 11 and III (P < 0.01). All parameters were significantly higher in patients than controls. HGF showed a strong correlation with IL-6 and TNF-alpha and less with beta(2)M, CRP, NTx, and OC. We conclude that serum HGF levels are increased in advanced stages of MM disease and extended bone lesions. HGF correlates with IL-6 and TNF-alpha, which are cytokines involved in osteoclast stimulation in MM. However, an independent association of HGF with bone turnover markers was not shown in this study, thus its role in MM bone disease needs to be further clarified. (C) 2003 Wiley-Liss, Inc.

Background: Waldenstrom’s macroglobulinemia (WM) is an unusual lymphoplasmacytoid lymphoma characterized by the presence of a serum monoclonal immunoglobulin M. Although several studies have evaluated possible prognostic factors of this disease, few have focused on the survival and prognosis of symptomatic patients after the initiation of treatment. Patients and methods: Our study included 122 previously untreated patients with a median age of 67 years who required systemic treatment. Multiple variables were analyzed for their prognostic value on survival after initiation of treatment using univariate and Cox regression multivariate analysis. Results: The median overall survival was 106 months. Pretreatment factors associated with shorter survival were age greater than or equal to65 years, splenomegaly, B-symptoms (weight loss, fever or night sweats), hemoglobin

The standard CHOP regimen may cure 30-40% of patients with advanced aggressive non-Hodgkin’s lymphoma (ANHL). Mitoxantrone is an anthracenedione, which is active in NHL and its toxicity profile may be more favorable than doxorubicin with respect to alopecia, mucositis and cardiotoxicity. This study was designed to compare the effectiveness of an escalated dose of mitoxantrone with that of standard doxorubicin, used in the CHOP regimen in patients with ANHL. One hundred and forty three eligible patients with ANHL were randomized to receive 6 cycles of either CHOP (n = 71) or intensified CNOP (iCNOP) (n = 72); with mitoxantrone 20 mg/m(2), i.v., d.1 instead of doxorubicin. Complete responders (CR) were again randomized either to receive interferon-alpha (IFN-alpha) maintenance (3 MU t.i.w., s.c.) or not. The CR rate was 70 vs. 76% for iCNOP and CHOP (p = 0.45); and the overall response rate was 81 vs. 83%, respectively (p = 0.71). The 5-year failure free survival (FFS) was 48 and 50% in the iCNOP and CHOP arm, respectively (p = 0.45), and the 5-year overall survival (OS) was 61 vs. 64% (p = 0.56). IFN-alpha did not prolong relapse free survival (p = 0.91), iCNOP produced less alopecia (p = 0.001) but more febrile episodes (p = 0.04) than CHOP, while requiring more frequent G-CSF support (p = 0.01). Two cases of acute myelogenous leukemia (AML) were recorded, both in the iCNOP arm (p = 0.14). In conclusion, iCNOP was equally effective to CHOP in patients with ANHL, producing more leukopenia and febrile episodes, but less alopecia. The development of two cases of secondary AML in the iCNOP arm is of concern.

B cells in chronic lymphocytic leukaemia (CLL) usually express the CD5 antigen, which appears to participate in the pathogenesis of autoimmune phenomena. However, 7-20% of B-CLL patients are CD5(-). The aim of this study was to assess whether CD5 expression could be used as a discriminating factor for two subgroups of B-CLL. Twenty-nine CD5(-) B-CLL patients were compared in terms of clinico-biological characteristics and survival with a control group of 29 sex and age-matched, consecutive CD5(+) B-CLL subjects. B-CLL was considered to be CD5(-) when less than 5% of mononuclear cells expressed CD5 after subtraction of the number of T cells. Splenomegaly, lymph node involvement, and haemolytic anemia were found in CD5(+) patients in a significantly higher proportion than in their CD5- counterparts, who presented with an earlier stage of disease. CD5- patients had a median survival of 97.2 (22-130) months, exceeding CD5(+) subjects significantly [84.0 (19-120) months, p = 0.0025]. CD5(-) patients seemingly present with milder disease and have a favourable prognosis compared with the vast majority of B-CLL patients who express CD5.

Objective: To investigate the adrenal function in non-septic, long-stay critically ill patients. Design: Prospective, consecutive study. Setting: General intensive care unit in a university hospital. Patients: Forty-three non-septic patients with protracted critical illness. Interventions: A morning blood sample was first obtained to measure baseline plasma cortisol. Subsequently, 1 mug of corticotropin (ACTH, Synacthene) was injected intravenously and 30 min later a second blood sample was drawn to determine stimulated plasma cortisol. Patients having a stimulated cortisol level of at least 18 pg/dl were defined as responders. In 36 patients, morning interleukin-6 (IL-6) was also measured. Measurements and results: Baseline and stimulated plasma cortisol were 16.8 +/- 4.1 pg/dl and 21.2 +/- 5.1 pg/dl, respectively. Interleukin-6 was high (median 39.3 pg/ml, interquartile range 24.9-86.6 pg/ml) and correlated negatively with stimulated plasma corti-sol (r=-0.40, p

A 38-year-old man, without previous history of disease, was diagnosed with stage IIIB high-grade T-cell non-Hodgkin's lymphoma. He initially received eight cycles of cyclophosphamide (1350 mg), doxorubicin (90 mg), vincristine (2 mg) and prednisone (100 mg/day for 5 days) ^ CHOP regimen ^ with good response. The patient was disease-free for 3 years, after which the disease relapsed and he was scheduled to be treated with a total of six cycles of cyclophosphamide (1350 mg), mitoxantrone (36 mg), vincristine (2 mg), prednisone (100 mg/day for 5 days) and bleomycin (15 mg) ^ CNOP ^ Bleo regimen. Two weeks after the fourth CNOP ^ Bleo treatment cycle, painless onycholysis of all ¢ngernails and toenails became evident (Fig. 1). Onycholysis was accompanied by subungual haemorrhage, though no bleeding disorder was disclosed by the consequent laboratory investigation. No nail discoloration or other skin abnormality (including haemorrhagic lesions) on physical examination were noted.
