Chest x-ray resolution after SARS-CoV-2 infection.

Aim To analyse the resolution of chest X-ray findings in relation to laboratory parameters in patients infected with acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a two- month followup. Analysis of chest X-ray findings in the first few months after the disease is the main goal of our work. Methods Out of the total of 343 patients chest X-ray findings were followed in 269 patients. Patients were divided into groups according to the severity of findings. D-dimer, inflammatory markers, blood cell count, neutrophil lymphocyte ratio (NLR) were analysed. Chest X-ray was analysed during the hospitalization on the day of admission, on the third, the seventh and the fourteenth day (scoring method was used). After discharge chest X-ray was performed in a two-week follow-up, then after one and two months, and after three months if necessary. Results Incomplete chest X-ray resolution was identified in 24 (39.34%) patients with severe, 27 (22.31 %) patients with moderate and in three (3.91%) patients with mild findings. Statistical significance was established in overall score by comparison between all groups (p<0.001), and in the moderate compared to the mild group (p=0.0051). The difference of NLR in the severe compared to the moderate group was observed (p=0.0021) and in the severe group compared to the mild group (p=0.00013). Conclusion Chest X-ray findings persisted mostly in the severe group followed by the moderate and mild ones. Long-term followup is necessary for the appropriate treatment and prevention of fibrosis, and reduction of symptoms.

Alpha-lipoic acid reduces body weight and regulates triglycerides in obese patients with diabetes mellitus.

AIM: To determine an influence of alpha-lipoic acid to reduction of body weight and regulation of total cholesterol concentration, triglycerides and glucose serum levels in obese patients with diabetes mellitus type 2. METHODS: A prospective study includes two groups of obese patients with diabetes mellitus and signs of peripheral polyneuropathia: examined group (30 patients; 15 females and 15 males), and control group (30 patients; 12 females and 18 males). All were treated with metformin (850-1700 mg/day). Examined patients were additionally treated with alpha-lipoic acid 600 mg/day during 20 weeks. Body mass index and concentrations of total cholesterol, triglycerides and glucose in serum were compared before and after the treatment. RESULTS: The group treated with 600 mg alpha-lipoic acid lost significantly more weight, and had lower triglyceride level than the control group. There were no significant differences in total cholesterol and glucose serum levels between the groups. CONCLUSION: Alpha-lipoic acid of 600 mg/day treatment have influenced weight and triglycerides loss in obese patients with diabetes mellitus type 2. It should be considered as an important additive therapy in obese patients with diabetes mellitus type 2.

Changes of natriuretic peptides concentration in early phase of acute myocardial infarction.

AIM: To analyze a change of level of nautriuretic peptide (NT pro- BNP) caused by stress distension of myocardial wall in cases of acute myocardial infarction (AIM), as a possible predictor of early heart failure. METHODS: Patients with myocardial infarction were followed up. Standard clinical and laboratory examination, including NT pro- BNP, and other laboratory analyses, were performed on the day of admission, the next day and on the eighth day of hospitalization. Statistical analyses included variance for repeated measurement (ANOVA), factorial multivariate analysis and test of multiple correlations. RESULTS: The most important predictors of early heart failure in acute myocardial infarction were age, diastolic blood pressure, creatin kinase (CK) on admission, larger field of infarction zone and so on. Multiple correlations showed statistically significant correlation of age, diastolic pressure and larger zone of myocardial infarction with an increase of NT pro-BNP concentration. The activity of CK on the day after admission was higher than on admission (p=0.02) and myocard-binding CK (CK-MB) the next day after admission was higher than on admission (p=0.016). A statistically significant increase was found on the next day for NT pro-BNP in comparison with the value on admission (p=0.0049), but the level of activity of CK was markedly decreased on the eighth hospital day. CONCLUSION: The significant increase of the concentration of NT pro-BNP during myocardial infarction is an important predictor of early heart failure, therefore, in case of a significant increase of NT pro-BNP in the early phase of the infraction a therapy that could prevent clinically relevant heart failure should be administered .

Characteristics of acute abdominal pain in lower abdomen in patients hospitalized in general hospital Tesanj.

BACKGROUND: Pain in the lower abdomen is one of the leading reasons that lead the patient in surgery. Although appendicitis is the most common cause in about two thirds of patients the other causes must be taken into account. OBJECTIVES: To determine the probabilities which could determine what is an etiological cause of pain. MATERIALS AND METHODS: comprised 102 patients hospitalized in general hospital Tesanj because the clinical symptoms dominated by acute pain in the lower abdomen. The study was retrospective prospective clinical study. All data were collected in a special database and statistically analyzed. RESULTS: Of all the causes of abdominal pain in the lower abdomen the most common is appendicitis with a total of 62 patients, of which slightly more male patients (36) compared to female patients (26) or (57% male and 43% female patients). If we analyze the time elapsed from pain onset to patient visit of physician we can say that patient with more intense pain will visit physician sooner. Colic and intense pain is a characteristic of colon cancer (15 patients) and Crohn's disease. Dull pain is characteristic of omentum cyst, diverticulitis, and intestinal obstruction and was seen in one fifth of patients with colorectal cancer and one third of patients with acute appendicitis. Palpatory positive pain in Mc Burney's point distinguishes appendicitis from other causes in most cases. DISCUSSION: The decision-making in the treatment of abdominal pain is depending of nature of pain, intensity, spreading, and sensitivity to palpation and localization of pain that usually indicates the place where the sick organ transmits the inflammatory process to the parietal peritoneum. Other symptoms that accompany pain and laboratory tests can be of crucial importance.

Local CD4+, CD8+ and CD56+ reactions to lung cancer in regard to pathohistological type and clinical stage.

AIM: To determinate the difference of abundance of CD4+, CD8+ and CD56+ bronchoalveolar fluid's lymphocytes and their subpopulations between non- and small cell lung cancer. Also, the differences of abundance of examined lymphocytes were compared between main clinical stages of lung cancer. METHODS: Mini-bronchoalveolar lavate was taken from lungs of 55 patients with cancer. After laboratory processing and adding CD3, CD4, CD8, CD27, CD28 and CD56 antibody, the material was analysed by flow cytometer. Results of Mini-BAL for non- and small cell lung cancer were compared, as well as the different clinical stages of the disease. RESULTS: Immature and regulatory forms of lymphocytes are more activated, while mature and activated forms are less activated in small cell lung cancer compared to non small type. With an increase of the clinical stage of disease, immunological reaction of T lymphocytes is better expressed because of increasing of abundance of immature and regulatory forms of different subpopulations of lymphocytes. CONCLUSION: All components of local CD4+ and CD8+ T lymphocyte, as well as NK and NKT cells response were more activated in lungs with small cell lung cancer, and these reactions were more expressed with an increase in the clinical stage.

Use of amino-terminal pro-B type natriuretic peptide as the parameter for long-term monitoring of water overload in patient with chronic kidney diseases.

AIM: To analyze usefulness of measurement amino-terminal pro-B type natriuretic peptide of (NT pro-BNP) as the one of parameters of water overload in patients with chronic kidney diseases. METHODS: A total number of 277 patients with chronic kidney diseases (CKD) were followed up in the period often years between January 2000 and July 2010. Patients with creatinine clearance of 60 ml/min or less were included in the study. Changes of creatinine clearance, and in last five years changes of NT pro-BNP were followed. Water overload was analyzed using chest x-ray in relation with concentration of NT pro-BNP in the blood. RESULTS: Decrease of clearance of creatinine ranged from average 54.7 ml/min in the first year to 14.6 ml/min in the fifth year of the monitoring. Average NT pro-BNP level in patients without any sign of water overload was 94 pg/ml (SD 21), mean value in those with Kerley lines was 231 pg/ml/L (SD 64), in those with clear signs of water overload but without pleural effusion it was 525 pg/ml (SD 223), and in those with water retention including pleural effusion it was 1606 pg/ml (SD 1134). Using test of multiple correlation a statistically significant correlation between X-ray signs of water overload and NT pro-BNP concentration was shown, p < 0.05. CONCLUSION: Measurement of NT pro-BNP was increased in the beginning of water overload in patients with CKD. Increased value of NT pro-BNP may be found earlier than any other signs of water overload. NT pro-BNP was a useful parameter in estimation of water overload in these patients.

Local CD4+, CD8+ and CD56+ T-lymphocite Reaction on Primary Lung Cancer.

OBJECTIVE: The primary goal of this study was to determine the difference of abundance of CD4+, CD8+ and CD56+ bronchoalveolar fluid's lymphocytes and their subpopulations between cancerous lung and healthy lung from the same patient. METHODS: Mini-bronchoalveolar lavage was taken from 55 patients from lung with cancer and healthy lung. After laboratory processing and addition of CD4, CD8, CD27, CD28 and CD56 antibody, the material was analyzed by flow cytometer. Results from lung with cancer were compared to the ones from the healthy lung. The examined patients were the test and the control group at the same time. RESULTS: CD27+28+ forms of CD4+ and CD8+ lymphocytes are more activated in the cancerous lung compared to healthy lung, while the CD27-28- forms are less activated in diseased lung. CD4+ forms of CD56+ lymphocytes are more activated in cancerous lung compared to the health lung, while the CD8+ forms are less activated in diseased lung. CONCLUSION: Immature helper and cytotoxic T lymphocyte response, as well as regulatory NK and NKT cell response are more activated in cancerous lung compared to the health lung of the same patient.
