Objective. To investigate the effectiveness of first-line intravenous drugs (isoniazid and ethambutol) in patients with tuberculous meningitis and HIV during the intensive phase of chemotherapy. Materials and methods. 54 patients with newly diagnosed infiltrative pulmonary tuberculosis, tuberculous meningitis, and HIV were included in this study. The presence of Mycobacterium tuberculosis in sputum was observed in all patients. Group 1 consisted of 23 patients receiving ethambutol and isoniazid intravenously, and rifampicin and pyrazinamide were administered orally. Group 2 consisted of 31 patients treated with first-line oral anti-tuberculosis drugs. Serum isoniazid and ethambutol concentrations were determined by chromatographic method. Results. There was a greater improvement in clinical symptoms and radiographic evidence in patients receiving intravenous isoniazid and ethambutol compared with group 2. Positivity of sputum Mycobacterium tuberculosis was observed during the second month of treatment in 25.0 % of patients in group 1 and 76.1 % of patients in the control group (p=0.003). In addition, 9 (39.1 %) patients died before 6 months when isoniazid and ethambutol were administered intravenously compared with 22 (70.9 %) in group 2 (p=0.023). Conclusions. In tuberculous meningitis and HIV, intravenous treatment with isoniazid and ethambutol was more effective than oral treatment for 2 months of intensive treatment in the form of faster sputum conversion, clinical improvement, and higher mean concentrations of isoniazid and ethambut blood. In addition, mortality was lower with intravenous isoniazid and ethambutol compared with oral treatment.

Objective. To investigate the effectiveness of infusion chemotherapy in patients with pulmonary tuberculosis (TB) with treatment failure and malabsorption syndrome. Materials and methods. We observed 52 patients with newly diagnosed pulmonary TB with treatment failure, who were diagnosed with malabsorption syndrome. Patients were divided into two groups: 1st group (main) included 24 patients who received rifampicin and ethambutol intravenously, pyrazinamide and isoniazid orally; 2nd group (control) – 28 patients who received standard therapy orally. The severity of malabsorption syndrome was determined by a violation of intestinal penetration. Intestinal penetration was determined by the concentration of lactulose and mannitol (lactulose-mannitol test) in urine. The concentration of rifampicin, isoniazid, ethambutol in the serum was determined by liquid chromatography on a chromatograph Perkin Elmer (USA). Results and discussion. The examination revealed a violation of the rate of intestinal penetration in all studied patients, compared with healthy donors. The concentration of anti-TB drugs in the serum was significantly lower than the therapeutic average in group 2 compared with group 1 (p<0,05). In patients of group 1 after the intensive phase of treatment, the disappearance of clinical symptoms of the disease was observed in 22 (91.3±5.8 %) and 17 (60.7±6.3 %) patients (p<0.05), cessation of mycobacterial excretion – in 20 (83.3±4.3 %) and 14 (50.4±4.6 %) (p<0.05), resorption of infiltrative changes and healing of destruction cavities in the lungs – in 12 (50.2±5.3 %) and 10 (35.7±4.7 %) (p<0.05) compared with group 2. Conclusions. In patients with malabsorption syndrome with ineffective treatment and low intestinal penetration, which leads to reduced serum concentrations of anti-TB drugs in the intensive phase of treatment, it is advisable to increase the effectiveness of intravenous rifampicin and ethambutol.

Objective: To evaluate the role of cerebrospinal fluid (CSF) polymerase chain reaction (PCR) for Mycobacterium Tuberculosis inrapid diagnosis of tuberculous meningitis (TBM). Study Design: Prospective observational study. Place and Duration of Study: Medical A unitHayat Abad Medical complex Peshawar from 1st September 2010 to 30th August 2011. Methodology: A total of 20 Patients having fever,constitutional symptoms (malaise, vague ill health, headache, vomiting), nuchal rigidity with altered mental and behavior changes weresuspected as TBM and hence included in the study. Patients were divided into two groups based on direct and indirect evidence of tuberculosisin central nervous system (CNS) of patients. Group1: Patients having direct evidence of mycobacterial infection in CNS as Acid Fast Bacillismear positive in CSF. Group 2: Patients with indirect evidence of TB in CNS in form of typical CSF findings of TBM, positive sputum smear forAcid fast bacilli (AFB) or computed tomographic (CT) Scan brain findings suggestive of TBM or evidence of TB in x-ray chest or family History oftuberculosis and/or history of contact with TB patients or positive Mantoux Test or evidence of TB elsewhere in the body. Results: Out of total 20patients, 3 (15%) belonged to Group 1 having direct evidence of TBM the remaining 17 (85%) patients belonged to Group 2. Female patientswere 60% while 40% patients were male. Mean age was 35.8 years. All patients had fever and headache. Productive cough was present in 40%patients. Thirty five percent had lost weight. Contact with TB patients was revealed in 35% patients. Signs of meningeal irritation were elicited in90% patients. Cranial nerve palsies were seen in 25% patients, 10% had hemiparesis while 35% had impairment of consciousness. X-ray chestwas normal in 65%.Computed tomographic scan was showing meningeal enhancement in 30% patients, hydrocephalus in 15% patients,meningeal enhancement plus hydrocephalus in 55% patients and infarct in 15% patients. Three patients were enrolled in group 1 and all hadPCR positive for mycobacterium tuberculosis. Of 17 patient in group 2, 64% patients had positive CSF PCR. Conclusions: Tuberculousmeningitis is an important serious extrapulmonary complication of TB, related with high mortality and morbidity. The prompt and accuratediagnosis of TBM is a daunting challenge. CSF PCR for Mycobacterium tuberculosis is an excellent test for rapid diagnosis of TBM.

The efficacy of Bacillus Calmette-Guerin (BCG), vaccine against tuberculosis (TB), varies widely, from 0 to 90%; and BCG mainly activates CD4+ T cells, but it fails to activate CD8+ T cells. From the previous study, 38-kDa protein is an adhesin protein. CD8+ T cells play the role in controlling Mycobacterium tuberculosis (M.tb) infection and contribute to the memory immunity. The objective of this study was to determine effect of oral immunization by 38-kDa adhesin protein of M.tb to increase the level of CD8+ T cells in the lung of BALB/c mice. This study used an experimental with post test control group design. The mice were divided into six groups (each group consist of 4 samples), where Group 1: were immunization orally with 100 μg 38-kDa adhesin protein of M.tb and 12 μg ISCOMs. Followed by group 2: 100 μg 38-kDa adhesin protein of M.tb, group 3: 50 μg 38-kDa adhesin protein of M.tb and 12 μg ISCOMs, and group 4: 50 μg 38-kDa adhesin protein of M.tb. Group 5: 12 μg ISCOMs. Group 6: Control. In this study was found increased level of CD8+ T cells in the lung of BALB/c mice after orally immunization with 38-kDa adhesin protein of M.tb. The highest level of CD8+ T cells was on group 1, p=0.000. Also there were found significant differences among the immunized groups, except group 2 and 3, as well as group 5 and 6 also. It can be concluded in this study that oral immunization with 38-kDa adhesin protein of M.tuberculosis could increase the level of CD8+ T cells in the lung of BALB/c mice.

We examined 56 normoprolactinemic women of reproductive age (18-45 y.o.) with isolated hypogonadotropic hypogonadism (group 1) initially and on treatment with 2 mg of 17beta-estradiol and 10 mg of dydrogesterone in sequenced manner (HRT), duration of HRT was from 18 to 42 (median 36) months; 45 healthy women (20-38 y.o.) were included in control group 2. Initially hypercholesterolemia was observed in 50% of cases in group 1 and 6.6% in group 2 (z=12,29, p=0,0005); nevertheless, the difference in lipid levels between groups 1 and 2 was not statistically significant: total cholesterol levels 5,2 (4,3; 6,0) mmol/l and 4,63 (4,15; 5,15) mmol/l respectively (1vs2, р=0,1); triglycerides 0,8 (0,62; 1,3) mmol/l and 0,76 (0,6; 0,85) mmol/l (1vs2, р=0,08); HDL 1,89 (1,24; 2,1) mmol/l and 1,79 (1,44; 2,8) mmol/l (1vs2, p=0,85); LDL 2,7 (2,2; 3,2) mmol/l and 2,75 (2,3; 3,3) mmol/l (1vs2, p=0,64). In group 1 decrease of total cholesterol and triglycerides concentrations was found on HRT: total cholesterol 4,8 (3,95; 5,1) mmol/l (before vs on treatment p=0,041), triglycerides 0,65 (0,6; 0,9) (before vs on treatment p=0,044) respectively, changes in HDL and LDL levels were not revealed. Initial concentrations of Ca++, P, and alkaline phosphatase (AP) were within normal range in all women. However, concentrations of Ca++ and AP were higher in group 1 compared to group 2: Ca++ 1,13 (1,08; 1,19) mmol/l and 1,05 (1,03; 1,09) mmol/l (1vs2, p=0,0016); AP 161,5 (141,8; 183) IU/l and 141,0 (119; 151) IU/l (1vs2, p=0,044). On HRT reduce in Ca++ and AP concentrations was observed: Ca++ concentrations 1,05 (1,03; 1,10) mmol/l (before vs on treatment p=0,004), AP 139 (112; 143) IU/l (before vs on treatment p=0,004). HRT was accompanied by improvement of clinical symptoms, had no influence on thyroid function, and provoked physiological rise of prolactin levels.Thus, despite lacking the expressed biochemical disorders, isolated hypogonadotropic hypogonadism in women of reproductive age have hidden negative impact on lipid and mineral metabolism. Long term HRT is safe and significantly improved parameters of lipid and mineral homeostasis in this cohort of patients.

The objective: was to evaluate the efficacy of the first line chemotherapy in patients with metastatic triple negative breast cancer (TNBC). Materials and methods. Open randomized study was performed including 122 patients with metastatic TNBC. The efficacy and safety of the first line chemotherapy of regimens АТ (n=59) – group 1, patients received doxorubicine 60 мг/м2 and paclitaxel 175 мг/м2 and ТР (n=63) – group 2, patients received paclitaxel 175 мг/м2 and carboplatin AUC 5 were evaluated. Results. The median duration of response was 9.5 months (4.5–13.25 months) in patients received AT regimen and 8.5 months (4.7–12.25 months), in TP regimen; no statistically significant differences were observed, р=0.836. The median progression free survival was 7 months (95% CI 5–26 months) in group 1 and 7.5 months (95% CI 6–35 months) in group 2, p=0.85. Both chemotherapy regimens (AT and TP) had mild or moderate toxicity profiles (grade 1 or 2 in most patients). No significant difference in gastrointestinal toxicity was observed. The incidence of grade 3–4 neutropenia was higher in patients of group 2 (TP regimen): 42.8% versus 27% (р<0.05). Conclusions. Both regimens of chemotherapy (AT and TP) are appropriate to use in the first line setting in patients with metastatic TNBC. Key words: metastatic triple negative breast cancer, chemotherapy, progression free survival, chemotherapy toxicity.

The purpose of the study was to conduct a comparative assessment of the course of the postoperative period after phlebectomy and thermal ablation in patients with varicose veins of the lower extremities in the system of the great saphenous vein (GSV) with class C2 of chronic venous insufficiency (CVI) — CEAP class C2. Materials and methods: 455 patients (455 limbs) with CEAP class C2. Group 1 (n = 154) received stripping + minimally invasive phlebectomy; Group 2 — endovenous laser ablation (EVLA) of GSV trunk + sclerotherapy of varicose veins; 3 group (n = 150) — radiofrequency ablation (RFA) of the GSV + sclerotherapy. All patients were united by a single tactical solution — the elimination of pathological vertical reflux in GSV. In each group, patients were with similar hemodynamic profile were selected (Group 1 = 63; Group 2 = 61; Group 3 = 61). The course of the postoperative period (from 2 days to 2 months) was compared for pain (visual analog scale — VAS), clinical symptoms of chronic venous insufficiency, degree of satisfaction (Darvall questionnaire), and duration of disability. Statistical processing was carried out using Excel programs for Windows XP, MedCalc® (version 11.4.2.0., Mariakerke, Belgium). Results: Postoperative pain is more pronounced (during day 1 for Group 1–4.0, Group 2–3.0, Group 3–2.0) and more prolonged (up to 4 days) after open surgeries (p < 0.05). The dynamics of the clinical symptoms of CVI (including varicose syndrome and use of compression therapy) could not be fully evaluated in connection with the ongoing sclerotherapy procedures for patients of Groups 2 and 3. Satisfaction of patients with aesthetic aspects was higher than expected in all groups. Reliable statistical differences proved decrease in days of disability (Group 1–14; Group 2–4; Group 3–3) and earlier return to physical activities and work in patients after thermal ablation in comparison with phlebectomy. Conclusion: The study shows that all three methods for eliminating vertical reflux in the GSV can be proposed for a large category of patients with CEAP of class C3 and C2. Medical and social rehabilitation of patients using endovascular thermal ablation technologies proceeds faster, which is beneficial both for the patients and for society.

Introduction: Removable dentures are used by 20% of the population. These may be accompanied by denture stomatitis in 15-70% of patients. The choice of the optimal cleansing agent for removable dental prostheses is of high significance. Aim: The aim of our research was to study the influence of removable denture cleansing products on the adhesion of microorganisms and yeast. Materials and Methods: We manufactured 144 specimens of standardized round shape with a diameter of 10 mm from 4 types of modern polymeric materials used by prosthetic dentistry to produce removable dentures, 12 specimens of each material were placed into suspensions of bacterial cultures of Staphylococcus aureus, Escherichia coli, Candida albicans, then into “ClearaSept” (Test group 1), “Рrotefix active cleanser” (Test group 2), saline solution (Control group), followed by nutrient media. The adhesion index was calculated and analyzed. Results: There was no reliable lowering of adhesion index of Staphylococcus Aureus to all materials detected in Test group 1 (U=6, p>0.05 for Bio XS; U=8, p>0.05 for Dental D, Denotokeep Peek, Vertex Rapid Simplified). In Test group 2, the adhesion index of Staphylococcus Aureus reliably decreased to all materials compared to the Control group (U=0, p≤0.01). The adhesion index of Candida albicans and Escherichia coli to all materials in Test group 1 had a minor to moderate reliable reduction compared to the Control group (U=0, p≤0.01). Test group 2 showed a significant reliable decrease in Candida albicans and Escherichia coli adhesion index to all materials in comparison with the Control group (U=0, p≤0.01). Conclusion: The research showed an unreliable or minor and moderate reliable decrease in microorganisms adhesion index depending on the microorganism species after treatment of denture material specimens by antibacterial soap “ClearaSept” and a reliable significant decrease in microbial and yeast adhesion after application of Protefix active cleaner solution, which demonstrates a more significant antimicrobial effect in comparison to “ClearaSept” against Staphylococcus aureus, Escherichia coli, and Candida albicans.

Effects of a dopamine-1 (DA-1) receptor agonist on systemic and intestinal oxygen delivery (D˙o 2)-uptake relationships were studied in anesthetized dogs during sequential hemorrhage. Control ( group 1) and experimental animals ( group 2) were treated similarly except for the addition of fenoldopam (1.0 μg · kg−1 · min−1) in group 2. Both groups had comparable systemic criticalD˙o 2(D˙o 2crit), but animals in group 2 had a higher gut D˙o 2crit(1.12 ± 1.13 vs. 0.80 ± 0.09 ml · kg−1 · min−1, P < 0.05). At the mucosal level, a clear biphasic delivery-uptake relationship was not observed in group 1; thus oxygen consumption by the mucosa may be supply dependent under physiological conditions. Group 2 demonstrated higher peak mucosal blood flow and lack of supply dependency at higher mucosalD˙o 2 levels. Fenoldopam resulted in a more conspicuous biphasic relationship at the mucosa and a rightward shift of overall splanchnic D˙o 2crit despite increased splanchnic blood flow. These findings suggest that DA-1 receptor stimulation results in increased gut perfusion heterogeneity and maldistribution of perfusion, resulting in increased susceptibility to ischemia.

Введение. Сосудистые осложнения сахарного диабета (СД) являются одной из ведущих причин повышения смертности пациентов трудоспособного возраста. Предполагается, что индуцированный гипергликемией окислительный стресс и нарушение антиоксидантной защиты играют роль в патологическом механизме повреждения сосудов, частично за счет влияния оксида азота (NО). Цель исследования: уточнение взаимосвязей в системах асимметричного диметиларгинина (АДМА) и NO у пациентов с цереброваскулярными заболеваниями (ЦВЗ) на фоне СД 2-го типа (СД-2). Материалы и методы. Обследованы 72 пациента с ЦВЗ со стенозирующим поражением внутренней сонной артерии вне острого периода: группу 1 составили 39 пациентов (18 мужчин и 21 женщина) с СД-2 в возрасте 65 [58; 72] лет; в группу 2 вошли 33 больных (15 мужчин и 18 женщин) без СД-2 в возрасте 66 [56; 74] лет. Контрольную группу составили 30 добровольцев (16 мужчин и 14 женщин) без проявлений церебральной ишемии и нарушений углеводного обмена, с нормальными значениями индекса массы тела, некурящие, в возрасте 62 [50; 66] лет. Проводилось клиническое обследование, нейро- и ангиовизуализационное исследование, спектр биохимических исследований крови, в том числе определение содержания АДМА и показателей системы NO. Результаты. В группе 1 содержание нитрата, нитрита и NO составило 62,1 [56; 68] мкмоль/л, 48,5 [26; 52] мкмоль/л и 13,6 [9; 23] мкмоль/л соответственно, что достоверно отличалось от значений этих показателей в группе 2 — 58,3 [45; 64] мкмоль/л, 39,6 [26,0; 42,3] мкмоль/л и 18,7 [16,1; 24,7] мкмоль/л соответственно. Отмечен также более высокий уровень AДМА в крови у пациентов с ЦВЗ в сочетании с СД-2 — 0,42 [0,21; 0,53] ммоль/л. Заключение. Обнаружена взаимосвязь между уровнями AДМА и NO при ЦВЗ на фоне СД-2. Это требует продолжения исследований биомаркеров повреждения сосудистой стенки для определения их места в патогенезе ишемических церебральных осложнений СД-2. Background. Vascular complications of diabetes mellitus (DM) are one of the leading causes of increased mortality in patients of employable age. Hyperglycemia-induced oxidative stress and impaired antioxidant protection have been suggested to play a role in the pathological mechanism of vascular damage, in part due to the effects of nitric oxide (NO). Objectives: clarification of relationships in the systems of asymmetric dimethylarginine (ADMA) and NO in patients with cerebrovascular diseases (CVD) and type 2 diabetes (DM-2). Patients/Methods. We examined 72 CVD patients with stenosing lesions of the internal carotid artery outside the acute period: group 1 consisted of 39 patients (18 men and 21 women; 65 [58; 72] years old) with DM-2; group 2 consisted of 33 patients (15 men and 18 women; 66 [56; 74] years old) without DM-2. The control group consisted of 30 volunteers (16 men and 14 women; 62 [50; 66] years old) without manifestations of cerebral ischemia and carbohydrate metabolism disorders, with normal body mass index, non-smokers. A clinical examination, neuro- and angio-imaging study, a spectrum of biochemical blood tests, including the concentration of asymmetric dimethylarginine (ADMA) and indicators of NO system were carried out. Results. In group 1, the content of nitrate, nitrite and NO was 62.1 [56; 68] μmol/l, 48.5 [26; 52] μmol/l and 13.6 [9; 23] μmol/l, respectively, that significantly differed from the content of these parameters in group 2 — 58.3 [45; 64] μmol/l, 39.6 [26.0; 42.3] μmol/l and 18.7 [16.1; 24.7] μmol/l, respectively. Noted also a higher blood level of ADMA in patients with CVD combined with DM-2 — 0.42 [0.21; 0.53] mmol/l. Conclusions. A relationship was found between ADMA and NO levels in CVD patients with DM-2. This requires further studies of biomarkers of vascular wall damage to determine their place in the pathogenesis of ischemic cerebral complications of DM-2.
