Abstract

CD56, p53, and Cyclin D1 detection in plasma cells (PC) can help to predict prognosis of multiple myeloma (MM). Clinical and biochemical prognostic parameters were analysed in a group of 122 patients with primary diagnosed MM in the period 2011–2015. Bone marrow biopsies were analysed with Cyclin D1, p53, CD56 antibodies. Statistical analysis was performed using Microsoft Excel 2010 and Graph Pad Prism 5. Lack of CD56 expression and p53-positivity were significantly correlated with a low glomerular filtration rate (GFR), low platelet count and haemoglobin level, as well as with high serum creatinine levels. Patients with Cyclin D1 expression in PC had a significantly higher serum calcium level and more common osteolytic lesion in bones. CD56-negative as well as p53, Cyclin D1-positive groups had advanced Salmon–Durie MM stages by and significantly higher ß2-microglobulin. Expression of p53, Cyclin D1 and lack of CD56 antigen in PC are negative predictive factors in cases of MM, as these patients were diagnosed as having late Salmon–Durie stage and higher ß2-microglobulin level. Expression of p53 and lack of CD56 antigen in PC is associated with an increased creatinine level in blood and decreased GFR; therefore, these are criteria for chronic renal failure progression and poorer prognosis of MM.

Abstract

Capsule Enteroscopy (CE) is a fundamentally new method in diagnostic endoscopy. However, there are several factors influencing the quality of this procedure, including impermeable fluids, food remains etc. The aim of the study was to assess one of the most popular currently used bowel preparation methods and evaluate possible effects of various factors. 136 CE examinations were analysed. Each patient was prepared using 2 litres of polyethylene glycol (PEG) one day prior to examination. There was a special form filled in for each patient, which included relevant parameters (anamnesis, CE data etc.). Of 136 CE cases, 84 (61.8%) were female patients and 52 (38.2%) were male. The small bowel (SB) transit time in 112 patients varied from 39 to 502 minutes, but in 24 cases the capsule did not reach caecum. The degree of bowel cleanliness was as follows: very good — 30 (22.1%) patients, satisfactory — 97 (71.3%), and poor — 9 (6.6%). A positive correlation was observed between the degree of SB cleanliness and the SB transit time (p = 0.015). A longer SB transits time was associated with poor SB cleanliness. The results obtained in this study showed that the quality of SB cleanliness is affected by SB transit time. A relatively large percentage of cases rated as satisfactory bowel cleanliness and comparatively small percentage of bowel cleanliness cases rated as “very good” were observed when 2 litres of PEG were used prior to CE, indicating an important issues in preparation of the bowel prior to CE.
