Hypertensive emergency due to a delayed dialysis modality transition in a patient with familial hypomagnesemia with hypercalciuria and nephrocalcinosis: a case report. EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2024; 28:3313-3317.

Abstract
BACKGROUND: This case report presents a history of familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC). The patient was admitted to the hospital with hypertensive encephalopathy. FHHNC is a rare autosomal recessive disease caused by mutations in CLDN16 or CLDN19, resulting in insufficient magnesium and calcium kidney reabsorption. FHHNC manifestation starts in childhood, and over the years, its development leads to nephrocalcinosis and, consequently, chronic kidney disease (CKD), which is not slowed by routine administration of magnesium and thiazide diuretics. Ultimately, all FHHNC patients need kidney replacement therapy (KRT). CASE PRESENTATION: The patient was a 28-year-old male diagnosed with FHHNC and admitted to the emergency room due to hypertensive encephalopathy. The current situation was the patient's second hospitalization related to a hypertensive emergency caused by under-dialysis. Despite the signs of insufficient functioning of peritoneal dialysis (PD) (the primary chosen form of KRT), the patient refused the proposed conversion to hemodialysis (HD). Symptoms observed upon admission included disorientation, anxiety, and severe hypertension, reaching 213/123 mmHg. Due to his clinical condition, the patient was transferred to the intensive care unit (ICU), where the introduction of continuous veno-venous hemodiafiltration and hypotensive therapy stabilized blood pressure. Within the next few days, his state improved, followed by discharge from ICU. Eventually, the patient agreed to transition from PD to in-center HD. At the time, he was qualified for kidney transplantation, waiting for a compatible donation. CKD and dialysis are factors that significantly affect a patient's quality of life, especially in young patients with congenital diseases like FHHNC. CONCLUSIONS: For the aforementioned reasons, appropriate education and psychological support should be ensured to avoid the harmful effects of therapy non-compliance.

The Real-World Evidence on the Fragility and Its Impact on the Choice of Treatment Regimen in Newly Diagnosed Patients with Multiple Myeloma over 75 Years of Age. Cancers (Basel) 2023; 15:3469. [PMID: 37444579 DOI: 10.3390/cancers15133469] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 06/24/2023] [Accepted: 06/30/2023] [Indexed: 07/15/2023] Open
Abstract
Fragility scales are intended to help in therapeutic decisions. Here, we asked if the fragility assessment in MM patients ≥ 75 years old qualified for treatment by the local physician correlates with the choice of treatment: a two- or three-drug regimens. Between 7/2018 and 12/2019, we prospectively enrolled 197 MM patients at the start of treatment from the 13 Polish Myeloma Group centers. The data to assess fragility were prospectively collected, but centrally assessed fragility was not disclosed to the local center. The activity of daily living (ADL) could be assessed in 192 (97.5%) and was independent in 158 (80.2%), moderately impaired in 23 (11.7%), and 11 (5.6%) in completely dependent. Patients with more than three comorbidities made up 26.9% (53 patients). Thus, according to the Palumbo calculator, 43 patients were in the intermediate fitness group (21.8%), and the rest belonged to the frailty group (153, 77.7%). Overall, 79.7% of patients (157) received three-drug regimens and 20.3% (40) received two-drug regimens. In each ECOG group, more than three out of four patients received three-drug regimens. According to the ADL scale, 82.3% of the independent 65.2% of moderately impaired, and 81.8% of the dependent received three-drug regimens. Out of 53 patients with at least four comorbidities, 71.7% received three-drug regimens, and the rest received two-drug regimens. Thirty-four patients from the intermediate fit group (79.0%), and 123 (79.9%) from the frail group received three-drug regimens. Early mortality occurred in 25 patients (12.7%). No one discontinued treatment due to toxicity. To conclude, MM patients over 75 are mainly treated with triple-drug regimens, not only in reduced doses, regardless of their frailty scores. However, the absence of prospective fragility assessment did not negatively affect early mortality and the number of treatment discontinuations, which brings into question the clinical utility of current fragility scales in everyday practice.

Abstract
Patients with myelofibrosis (MF) who discontinue ruxolitinib due to progression/resistance have poor prognoses. JAK inhibitors control symptoms and reduce spleen volumes with limited impact on underlying disease pathophysiology. Murine double minute 2 (MDM2), a negative regulator of p53, is overexpressed in circulating malignant CD34+ MF cells. The oral MDM2 inhibitor navtemadlin (KRT-232) restores p53 activity to drive apoptosis of wild-type TP53 tumor cells by inducing expression of pro-apoptotic Bcl-2 family proteins. Navtemadlin demonstrated promising clinical and disease-modifying activity and acceptable safety in a phase II study in patients with relapsed/refractory MF. The randomized phase III BOREAS study compares the efficacy and safety of navtemadlin to best available therapy in patients with MF that is relapsed/refractory to JAK inhibitor treatment.

Immunogenicity and safety of the adjuvanted recombinant zoster vaccine in adults with haematological malignancies: a phase 3, randomised, clinical trial and post-hoc efficacy analysis. THE LANCET. INFECTIOUS DISEASES 2019; 19:988-1000. [PMID: 31399377 DOI: 10.1016/s1473-3099(19)30163-x] [Citation(s) in RCA: 113] [Impact Index Per Article: 22.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/20/2018] [Revised: 03/06/2019] [Accepted: 03/28/2019] [Indexed: 12/18/2022]
Abstract
BACKGROUND The adjuvanted recombinant zoster vaccine (Shingrix) can prevent herpes zoster in older adults and autologous haemopoietic stem cell transplant recipients. We evaluated the safety and immunogenicity of this vaccine in adults with haematological malignancies receiving immunosuppressive cancer treatments. METHODS In this phase 3, randomised, observer-blind, placebo-controlled study, done at 77 centres worldwide, we randomly assigned (1:1) patients with haematological malignancies aged 18 years and older to receive two doses of the adjuvanted recombinant zoster vaccine or placebo 1-2 months apart during or after immunosuppressive cancer treatments, and stratified participants according to their underlying diseases. The co-primary objectives of the study were the evaluation of safety and reactogenicity of the adjuvanted recombinant zoster vaccine compared with placebo from the first vaccination up to 30 days after last vaccination in all participants; evaluation of the proportion of participants with a vaccine response in terms of anti-glycoprotein E humoral immune response to the adjuvanted recombinant zoster vaccine at month 2 in all participants, excluding those with non-Hodgkin B-cell lymphoma and chronic lymphocytic leukaemia; and evaluation of the anti-glycoprotein E humoral immune responses to the vaccine compared with placebo at month 2 in all participants, excluding those with non-Hodgkin B-cell lymphoma and chronic lymphocytic leukaemia. We assessed immunogenicity in the per-protocol cohort for immunogenicity and safety in the total vaccinated cohort. The study is registered with ClinicalTrials.gov, number NCT01767467, and with the EU Clinical Trials Register, number 2012-003438-18. FINDINGS Between March 1, 2013, and Sept 10, 2015, we randomly assigned 286 participants to adjuvanted recombinant zoster vaccine and 283 to placebo. 283 in the vaccine group and 279 in the placebo group were vaccinated. At month 2, 119 (80·4%, 95% CI 73·1-86·5) of 148 participants had a humoral vaccine response to adjuvanted recombinant zoster vaccine, compared with one (0·8%, 0·0-4·2) of 130 participants in the placebo group, and the adjusted geometric mean anti-glycoprotein E antibody concentration was 23 132·9 mIU/mL (95% CI 16 642·8-32 153·9) in the vaccine group and 777·6 mIU/mL (702·8-860·3) in the placebo group (adjusted geometric mean ratio 29·75, 21·09-41·96; p<0·0001) in all patients, excluding those with non-Hodgkin B-cell lymphoma and chronic lymphocytic leukaemia. Humoral and cell-mediated immune responses persisted above baseline until month 13 in all strata and, as expected, vaccine was more reactogenic than placebo (within 7 days after vaccination pain was reported by 221 [79·5%] of 278 vaccine group participants and 45 [16·4%] of 274 placebo group participants; fatigue was reported by 162 [58·3%] of 278 vaccine group participants and 102 [37·2%] of 274 placebo group participants). Incidences of unsolicited or serious adverse events, potential immune-mediated diseases, disease-related events, and fatal serious adverse events were similar between the groups. INTERPRETATION The immunocompromised adult population with haematological malignancies is at high risk for herpes zoster. The adjuvanted recombinant zoster vaccine, which is currently licensed in certain countries for adults aged 50 years and older, is likely to benefit this population.

Abstract
Background Patients with hematologic malignancies treated with anticancer immunosuppressive therapies (ITs) are at increased risk of herpes zoster (HZ). In a previous report of this phase 3, observer-blind, multicenter trial (NCT01767467), the adjuvanted recombinant zoster vaccine (RZV) was shown to be immunogenic and well-tolerated in ≥18 years of age patients with hematologic malignancies who completed or were undergoing anticancer IT.1 Here we report end-of-study results from the same trial. Methods Participants were randomized 1:1 to receive 2 doses of RZV or placebo (PL) 1–2 months apart, either ≥10 days before or after a cancer therapy cycle, or 10 days to 6 months after cancer therapy ended. Humoral and cell-mediated immune (CMI) responses were evaluated at 1 month and 12 months post-dose 2 (month 2 and month 13, respectively). Confirmatory objectives were to evaluate humoral response rate to RZV and to compare humoral immune responses to RZV and PL at month 2 excluding either subjects with chronic lymphocytic leukemia and non-Hodgkin B-cell lymphoma (NHBCL), or only those with NHBCL. Efficacy against HZ was explored in a post-hoc analysis of confirmed HZ cases. Solicited and unsolicited adverse events (AEs) were recorded for 7 and 30 days after each dose, respectively. Serious AEs (SAEs) and potential immune-mediated diseases (pIMDs) were recorded throughout the study. Results Of the 562 (RZV: 283, PL: 279) treated participants, 415 (RZV: 217, PL: 198)/310 (RZV: 168, PL: 142) were included in the according-to-protocol (ATP) cohort for humoral immunogenicity/immune persistence. The ATP sub-cohort for CMI included 132 (RZV: 69, PL: 63) participants at month 2 and 100 (RZV: 54, PL: 46) at month 13. All confirmatory immunogenicity objectives were met (Table 1). RZV efficacy against HZ, assessed post-hoc, was 87.2% (Table 2). RZV was more reactogenic than PL. The occurrence of unsolicited AEs, SAEs, and pIMDs was similar between the study groups (Table 3). Conclusion RZV induced robust humoral and cellular immune responses and showed an effect in the reduction of HZ incidence in patients with hematologic malignancies who completed or were undergoing anticancer IT. No safety concerns were identified. Reference 1. Oostvogels et al. IDWeek2017, abs 1344. ![]()

Efficacy and Safety of IQYMUNE®, a Ten Percent Intravenous Immunoglobulin in Adult Patients With Chronic, Primary Immune Thrombocytopenia. J Hematol 2018; 7:87-95. [PMID: 32300420 PMCID: PMC7155829 DOI: 10.14740/jh385w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2018] [Accepted: 05/07/2018] [Indexed: 01/09/2023] Open
Abstract
Background Intravenous immunoglobulin (IVIG) IQYMUNE® is a highly purified 10% IVIG that was assessed using the new stringent definition of response described in the revised guideline on the clinical investigation of IVIG. The efficacy and the safety of IQYMUNE® were investigated in adult patients with chronic primary immune thrombocytopenia (ITP). Methods In this phase III multinational, multicentre, prospective, uncontrolled, open-label, single-arm study, adult patients with a baseline platelet count < 30 × 109/L were treated with IVIG 10% at a dose of 2 g/kg body weight administered over 2 consecutive days. The primary endpoint was Response over the study period and was defined according to the recent and most stringent European Medicines Agency guidelines (platelet count ≥ 30 × 109/L and a ≥ 2-fold increase from baseline, no new bleeding, and no concomitant treatment with drugs that affect platelet count and/or induce bleeding cessation). Results Thirty-eight patients were enrolled; 73 infusions were administered (38 on Day 1 and 35 on Day 2). Response was reached by 24 patients corresponding to 63.2% of patients in the full analysis set (95% CI: 46.0; 78.2) and 68.6% of patients in the per-protocol set (95% CI: 50.7; 83.1). The median time to Response was 1 day. The median duration of Response was 13.5 days. Reasons for non-response were failure to reach the required platelet count (n = 12), a new bleeding event (n = 1), and forbidden medication use (n = 1). Among the 23 patients with a baseline platelet count ≤ 20 × 109/L, 19 patients (82.6%) achieved a platelet count ≥ 50 × 109/L at least once before Day 5 (previous European Medicines Agency definition of response). Treatment was well tolerated even in patients with a high flow rate (≥ 6 mL/kg/h in 40% of patients). Headache (34.2%), pyrexia (15.8%), and creatinine renal clearance decrease, including one case of decrease in glomerular filtration rate (10.5%) were the most frequently reported drug-related adverse events. Conclusions Administration of IQYMUNE® for 2 consecutive days at a dose of 2 g/kg was safe and efficacious. These results support the treatment of adult patients with chronic ITP with IQYMUNE®.

Abstract
GREEN (NCT01905943) is a non-randomized, open-label phase IIIb study investigating obinutuzumab alone or plus chemotherapy in chronic lymphocytic leukemia (CLL). We report a preplanned subgroup analysis of 158 previously untreated CLL patients receiving obinutuzumab-bendamustine (G-B). Patients received six 28-day cycles (C) of G-B: obinutuzumab day (D)1/D2 of C1 (25 mg D1/975 mg D2), 1000 mg D8 and D15 of C1, and D1 of C2-6; and bendamustine 70/90 mg/m2 D1 and D2 of C1-6. The primary endpoint was safety/tolerability. Grade ≥3 adverse events (AEs) occurred in 82.3% of patients, including neutropenia (49.4%), thrombocytopenia (12.0%) and febrile neutropenia (10.8%). Serious AEs included neutropenia (12.7%), febrile neutropenia (9.5%) and pneumonia (7.6%). Rates of grade ≥3 infections and infusion-related reactions were 20.3% and 17.1%, respectively. Due to tumor lysis syndrome (TLS; 8.2%), including two associated fatalities (one in another study cohort), additional risk-minimization measures were implemented. Overall response rate was 81.0%. After 32.8 months' median observation time, 2-year progression-free survival was 81.8%. Minimal residual disease was undetectable in 59.5% (94/158) and 27.8% (44/158) of patients for blood and bone marrow, respectively. Frontline G-B appears to have manageable toxicity with clinical activity in CLL. Careful TLS risk assessment, pretreatment and monitoring is required.

Abstract
Background Interim PET after two ABVD cycles (iPET2) predicts treatment outcome in classical Hodgkin's lymphoma. To test whether an earlier assessment of chemosensitivity would improve the prediction accuracy, we launched a prospective, multicenter observational study aimed at assessing the predictive value of iPET after one ABVD (iPET1) and the kinetics of response assessed by sequential PET scanning. Patients and methods Consecutive patients with newly diagnosed classical Hodgkin's lymphoma underwent interim PET scan after one ABVD course (iPET1). PETs were interpreted according to the Deauville score (DS) as negative (-) (DS 1-3) and positive (+) (DS 4, 5). Patients with iPET1 DS 3-5 underwent iPET2. Results About 106 early (I-IIA) and 204 advanced (IIB-IV) patients were enrolled between January 2008 and October 2014. iPET1 was (-) in 87/106 (82%) or (+) in 19/106 (18%) of early, and (-) in 133/204 (65%) or (+) in 71/204 (35%) of advanced stage patients, respectively. Twenty-four patients were excluded from response analysis due to treatment escalation. After a median follow-up of 38.2 (3.2-90.2) months, 9/102 (9%) early and 43/184 (23%) advanced patients experienced a progression-free survival event. At 36 months, negative and positive predictive value for iPET1 were 94% and 41% (early) and 84% and 43% (advanced), respectively. The kinetics of PET response was assessed in 198 patients with both iPETs. All 116 patients with iPET1(-) remained iPET2(-) (fast responders), 41/82 with IPET1(+) became iPET2(-) (slow responders), and the remaining 41 stayed iPET2(+) (non-responders); progression-free survival at 36 months for fast, slow and non-responders was 0.88, 0.79 and 0.34, respectively. Conclusion The optimal tool to predict ABVD outcome in HL remains iPET2 because it distinguishes responders, whatever their time to response, from non-responders. However, iPET1 identified fast responders with the best outcome and might guide early treatment de-escalation in both early and advanced-stage HL.

Abstract
We compared the outcomes of multiple myeloma (MM) patients aged 21-40 and 41-60 years in the novel agent era. This case-control study included 1089 patients between 2000 and 2015. Cases and controls were matched for sex, International Staging System (ISS) stage and institution. There were 173 patients in the younger group and 916 patients in the older group. Younger patients presented with a higher incidence of lytic lesions (82% vs. 72%; P = 0·04) and high-risk cytogenetic abnormalities (83% vs. 68%; P = 0·007), but lower rate of elevated lactate dehydrogenase (21% vs. 44%; P < 0·001). Five- and 10-year overall survival (OS) in younger versus older patients was 83% vs. 67% and 56% vs. 39%, respectively (P < 0·001). Similar results were seen when studying the subset of 780 patients who underwent autologous transplantation. Younger patients with ISS stage 1 had a better OS than older patients (P < 0·001). There was no survival difference between younger and older patients with ISS stage 2 or 3. Younger MM patients, aged 21-40 years, treated in the era of novel agents have a better OS than their counterparts aged 41-60 years, but the survival advantage observed in younger patients was lost in more advanced stages of MM.

Abstract
The association of single-nucleotide polymorphisms (SNPs) of B-cell activating factor (BAFF)/a proliferation-inducing ligand (APRIL) system with B-cell chronic lymphocytic leukemia (B-CLL) have been suggested, therefore, we investigated 20 SNPs of BAFF, APRIL, BAFF-R, transmembrane activator and calcium modulator and cyclophilin-ligand interactor (TACI), B-cell maturation antigen (BCMA) genes and the risk and outcome of B-CLL in 187 patients and 296 healthy subjects as well as ligand-receptor gene × gene interactions. Although the obtained P-values for all 20 SNPs did not reach statistical significance for this study (α = 0.003), the high value of the global chi-squared statistic (χ(2) df = 38 = 52.65; P = 0.0586), and obtained values of odds ratio indicate that rs9514828 (BAFF), rs3803800 (APRIL) and rs4985726 (TACI) may be associated with the risk of B-CLL. We observed that the B-CLL patients with the genotype rs9514828CT/rs11570136AA were diagnosed with the disease 12 years later than the whole group of patients in this study.

Abstract
BACKGROUND Multiple myeloma (MM) is associated with increased risk of venous and arterial thromboembolism. Formation of denser and poorly lysable fibrin clots is observed in patients with arterial and venous thromboembolism. We investigated fibrin clot properties and their determinants in MM patients. MATERIALS AND METHODS Ex vivo plasma fibrin clot permeability, turbidity and susceptibility to lysis were evaluated in 106 MM patients at the time of diagnosis vs. 100 age- and sex-matched controls. MM patients had lower clot permeability (Ks ), compaction, indicating denser fibrin clots, impaired fibrin polymerization with longer lag phase and lower final turbidity (D-Dmax ), combined with hypofibrinolysis reflected by longer lysis time and slower rate of D-dimer release from fibrin clots (D-Drate ) compared with controls (all P < 0·001). RESULTS Patients with IgG MM had lower Ks compared with IgA MM [5·9 (5·1-6·4) vs. 6·3 (5·9-7·2) 10(-9) cm(2) ; P = 0·007] and longer lysis time compared with light-chain-disease patients [11·4 (10·9-12·3) vs. 10·7 (9·8-11·9) min; P = 0·022]. Of the fibrin variables, only Ks was significantly lower in patients with International Staging System (ISS) grade III than in those with ISS grade I and II [5·9 (4·9-6·6) vs. 6·2 (5·7-6·8) 10(-9) cm(2) ; P = 0·015]. Multivariate analysis adjusted for age and fibrinogen showed that in MM patients elevated peak thrombin levels determine Ks and D-Dmax , while thrombin-activatable fibrinolysis inhibitor (TAFI) activity predicts Ks , t50% , D-Drate and lag phase. CONCLUSIONS Our study demonstrates prothrombotic fibrin clot phenotype in patients with MM, with a significant impact of increased thrombin formation and TAFI activity.

Abstract
The treatment of patients with multiple myeloma usually includes many drugs including thalidomide, lenalidomide and bortezomib. Lovastatin and other inhibitors of HMG-CoA reductase demonstrated to exhibit antineoplasmatic and proapoptotic properties in numerous in vitro studies involving myeloma cell lines. We treated 91 patients with relapsed or refractory multiple myeloma with thalidomide, dexamethasone and lovastatin (TDL group, 49 patients) or thalidomide and dexamethasone (TD group, 42 patients). A clinical response defined of at least 50% reduction of monoclonal band has been observed in 32% of TD patients and 44% of TDL patients. Prolongation of overall survival and progression-free survival in the TDL group as compared with the TD group has been documented. The TDL regimen was safe and well tolerated. The incidence of side effects was comparable in both groups. Plasma cells have been cultured in vitro with thalidomide and lovastatin to assess the impact of both drugs on the apoptosis rate of plasma cells. In vitro experiments revealed that the combination of thalidomide and lovastatin induced higher apoptosis rate than apoptosis induced by each drug alone. Our results suggest that the addition of lovastatin to the TD regimen may improve the response rate in patients with relapsed or refractory myeloma.

Abstract
A small subgroup of patients with hypereosinophilic syndrome (HES) demonstrates imatinib-sensitive fusion transcript-the FIP1L1-PDGFRA (F/P+). These cases are currently diagnosed as chronic eosinophilic leukaemia (CEL). In this paper, we screened 77 patients to estimate the frequency of FIP1L1-PDGFRA transcript among patients with unexplained, long-term hypereosinophilia exceeding 1.5 x 10(9)/L and to analyse the clinical and serological features in F/P+ CEL population. The FIP1L1-PDGFRA chimeric protein was detectable in 16 (14 males and 2 females) out of 77 examined HES patients (20%) by RT-PCR. Two patients suffered from cough at diagnosis. Three out of 16 (18%) patients had no organ involvements, in 5-one organ was affected and in the remaining eight cases-at least two. Eosinophilic organ damage/dysfunction identified splenomegaly in the majority of studied patients. We compared clinical and serological features between CEL F/P+ (n = 16) and HES (n = 61) patients. F/P+ cases had significantly increased WBC and absolute eosinophil count (AEC) at diagnosis (p = 0.008 and 0.02), whereas platelet count was decreased in this population (p = 0.03). Serum B12 and tryptase levels were increased (p = 0.002 and 0.004) in CEL F/P+ patients when compared to HES cases whereas serum IL-5 levels were significantly increased in the latter group (p = 0.01). Male gender and splenomegaly occurred more frequent in CEL F/P+ population (p = 0.002 and 0.0007, respectively). Additionally, patients with F/P+ CEL (n = 16) were compared with F/P- CEL (n = 8). The latter group, was significantly older, had lower AEC and higher platelet count. In conclusion, significant clinical symptoms are infrequent present and splenomegaly remains the most common organ involvement in patients with CEL expressing F/P fusion transcript. Our study confirmed the long-term remission on imatinib in this patient population.

Abstract
BACKGROUND Ultrasonography (US) is an easy and non-invasive technique of visualizing spleen. Thanks to its repeatability, it plays an important role in the diagnostics of, among others, developmental anomalies, such as supernumerary or lobated spleens, as well as focal lesions. It is also used in monitoring the size of the spleen and it considerably facilitates diagnosis after certain injuries. Thanks to the application of the Doppler method, it also facilitates the diagnostics of pathologies within the spleen's vessels. CASE REPORT This paper presents six different cases of focal lesions in the spleen, including lesions in the course of histiocytosis, in the course of sarcoidosis, as well as isolated abscesses of the spleen. The authors also present the case of a spleen with numerous metastatic lesions, the case of a near-splenic cyst, and the case of asymptomatic focal lesions of unknown origin. In all the presented cases, the lesions were accidentally revealed during ultrasonographic examination, which was the starting point for further diagnostics. CONCLUSIONS Though rare, morphologic lesions in the spleen should always be taken into consideration when performing a routine ultrasonographic examination of the abdominal cavity, and the organ itself should not be ignored. US is a widely available, noninvasive, and useful method for diagnosing splenic abnormalities, including focal changes.

Abstract
A typical symptom of microscopic colitis (MC) is chronic watery diarrhea with normal endoscopic findings and characteristic inflammatory changes in histopathology. Treatment of the disease is mainly empiric. MC has two main subtypes: lymphocytic colitis and collagenous colitis. There are also untypical histopathological forms of MC: MC with giant cells, MC not otherwise specified (NOS) and cryptal lymphocytic coloproctitis. Some other histopathological changes in MC have been observed, especially Paneth cell hyperplasia or epithelial degeneration. Eosinophilic colitis, acute colitis, amyloidosis, ulcerative colitis and Crohn's disease should be taken into consideration in differential diagnosis. The most reliable biopsy material for histopathological examination are samples obtained from transverse colon. Some studies proved that treatment of MC makes it possible to reduce not only clinical, but also histopathological, manifestations.

Abstract
BACKGROUND Transforming growth factor beta (TGF ) is involved in a variety of important cellular functions. The lack of TGF -dependent cell-growth control might be related to oncogenesis, as it has been shown in lung, breast, and colon carcinomas. Current observations have revealed that TGF is rather an inhibiting, not a stimulating, factor as far as malignant tumor development is concerned. Recently, however, there has been a growing number of reports on increased expression of TGF genes in certain tumors. In patients with a diagnosis of non-small-cell lung carcinoma, the tumors expressing high levels of TGF were the ones that had a higher proliferation and metastasis capability, whereas more promising were the cases with lower levels of TGF expression. MATERIAL/METHODS A pilot study of 14 patients was conducted comprising 8 patients with a low-grade lymphoma and 6 patients with a high-grade lymphoma. The QRT-PCR method was employed to assess the activity of TGF 1 and of its receptor types I, II, and III. RESULTS The expression values for TGF 1 and its receptors I, II, and III were twice as high in the group of patients with a diagnosis of high-grade lymphomas as in the group of patients diagnosed with low-grade lymphomas. CONCLUSIONS Results showed a clear difference in TGF 1 expression in patients with NHL depending on the subtype of the lymphoma, suggesting its significant role in the pathomechanism of this group of malignant diseases as well as its potential value as a prognostic factor.

Abstract
Wilson's disease defined also as hepatolenticular degeneration is an important clinical problem of young adults still causing diagnostic difficulties. In the course of the last decade, genetic background of the disease has been definitely established and elucidated, confirming the variety of genetic mutations, responsible for its origin. The current scheme of the disease treatment has been elaborated and established. It aims to eliminate the excess of toxic copper ions from the organism as fast as possible. In the initial phase of the treatment, traditional and recently introduced chelating agents administration usually results in prompt tissue copper deposits excretion and copper metabolism balance maintenance. In the chronic therapy, zinc compounds, inducing intestinal and hepatic metallothionein synthesis, have been gaining more common application. Life-long, constant, pharmacological Wilson's disease therapy, administered after its early diagnosis, allows for long periods of patients survival, frequently comparable to the normal population.

Abstract
Patients with advanced lymphogranulomatosis were divided into two subgroups. One, including 9 patients was treated in the hospital, and the second, including 21 patients, was treated at out-patient department. Results of the treatment and its adverse reactions were not significantly different in patients treated on out-patient basis and in hospital. However, unfavourable effect of therapy on patient's psychological status (anxiety) was less expressed in out-patient conditions. Such a way of treatment enables also considerable savings related to the repeated hospitalizations.

Abstract
Genetic predisposition and environmental factors (physical, chemical, hormonal and drugs inducing collagen-like syndrome) play an important role in the pathogenesis of the systemic lupus erythematosus. Elimination of these factors from the environment of the genetically predisposed individuals may prevent part of them against the disease. Basing on the above assumption, a chart of prophylaxis has been constructed and distributed among the mothers with the systemic lupus erythematosus, recommending prophylactic measures in both mothers and children. Within 1977-1987, 50 children were examined from time to time. Basic laboratory tests, phenomenon LE, antinuclear antibodies and antibodies anti-DNA have been determined. Transient presence of antinuclear antibodies was seen in 23 children. A tendency to an increase in the antibody titre was observed in girls of this group whereas a decrease in the titre was noted in the boys with the time lapse. Systemic lupus erythematosus prophylaxis in both mothers and children is uncomplicated and favourable for children. Regular determination of antibodies enables early diagnosis of the disease.
