Thus, use of biological active food additives (activators of the immune system) in acute and subacute forms of brucellosis was ineffective, on the other hand, it resulted in positive dynamics of immunological parameters in patients with chronic (primary and secondary chronic) forms of the disease.

Subpopulations of lymphocytes in patients with various forms of brucellosis disease in an endemic region before and after the standard treatment, in combination with immun-5 were studied. It was found that before treatment significant differences in cellular immunity parameters were obtained. In the acute form a significant reduction of T and B lymphocytes was observed. Most prolonged changes concerned CD3 +, CD4 +, CD8 +, CD20 +, lymphocytes. We can assume that deep depression of T-cell immunity contributes to development of complications, mainly due to a helper T cells.

The fact that the state of the B-cell immunity is not significantly differed in patients with primary subacute and chronic forms of brucellosis, confirms the viewpoint that the greatest susceptibility of B cells to the action of Brucella toxins compared to other immune cells. This study points to the highest sensitivity of B cells to damaging factors, taking place at the brucellosis infection. However, it is not excluded that the reduction of B cells is mediated by the combined effects of toxins Brucella on the immune system in total.

Conclusions:

1. The use of immune stimulator immun-5 in the complex treatment of acute and subacute brucellosis is inappropriate.

2. Positive immunological effect is observed in immun-5 inclusion in a complex therapy of chronic forms of the disease.

Keywords: ocular ischemic syndrome, the treatment of ischemic diseases of the eye, FDP, metabolic therapy of ocular isch-emic syndrome.

Introduction

Ocular ischemic syndrome is a rare condition, which is caused by ocular hypoperfusion due to stenosis or occlusion of the common or internal carotid arteries. Atherosclerosis is the major cause of changes in the carotid arteries Kearns & Hollenhorst [4]. OIS occurs

mostly in patients with poor collateral circulation between the internal and external carotid arteries or between the two internal carotid arteries Mendrinos, Machinie & Pournaras [6], Mizener, Podha-jsky & Hayreh [7]. Since OIS is associated with atherosclerosis, patients usually have other related co-morbidities. Hypertension is

found in 73 % of the patients and diabetes mellitus in 56 % Sharma & Brown [12]. Myocardial infarction occurs in approximately 4 % of patients with OIS Sharma & Brown [12]. The mortality rate is as high as 40 % within 5 years of onset Sharma & Brown [12]. Cardiovascular disease is the main cause of death (approximately 66 %), followed by stroke as the second leading cause of death Ryan, Hinton & Schachat [11], which is why patients with OIS should be referred to the cardiologist, for imaging studies of the carotid arteries, and to the vascular surgeon Barbara, Terelak-Borys, Katarzyna, Skonieczna, Iwona & Grabska-Liberek [1].

Therefore, during treatment of OIS, to eliminate hypoxic and ischemic processes, and improve metabolic processes should be performed courses of conservative therapy with drugs that improve metabolic processes in the tissues, as well as reduce the hypoxic manifestations in organs and tissues of the eye.

Such drug is the FDP, which is used in cardiology, neurology and pediatric neurology in ischemic processes of organs and tissues (ischemic stroke, myocardial infarction, and others).

Fructose-1,6-diphosphate (FDP) is a key intermediate in anaerobic glycolysis and is the product of the major regulatory enzyme in the pathway (phosphofructokinase). Preclinical and clinical data suggest that FDP has substantial cytoprotective effects in a variety of ischaemia-reperfusion injury scenarios. Evidence indicates that FDP has a direct effect on ATP pools, reduces ischaemia-induced tissue damage and has positive inotropic effects on heart function. The clinical data suggest that FDP may be a useful drug in a variety of ischaemic and inflammatory clinical settings where acute management of tissue injury is desired Paul J. Marangos, Anthony W. Fox, Bernhard J. Riedel, David Royston & Zofia, E. Dziewanowska [9].

According to the literature, intravenous injection of FDP during cerebral hypoxia and ischemia restores vital energy ofbrain cells, the ion gradient of neuronal membranes, thereby minimizing damage ofthe cerebral cells (Karaca, Kilic, Yazici, Demir & Torre [3]). In addition, the "surviving" effect of FDP is also demonstrated in ischemia of the kidneys, small intestine, coronary heart disease, brain disease, as well as with lower limb ischemia Karaca, Kilic, Yazici, Demir & Torre [3], Riedel, Gal, Ellis, Marangos, Fox & Royston [10].

Considering the above we conducted a study, where as an anti-ischemic and neuroprotective drug in patients with ocular ischemic syndrome used FDP.

Purpose

Evaluate the efficacy and safety of fructose-1,6-diphosphate in patients with ocular ischemic syndrome.

Material and methods

The material for this study is based on results of a comprehensive examination and treatment of 53 patients with a diagnosis OIS.

The study was conducted in the Republican Clinical Eye Hospital under the Ministry of Health of the Republic of Uzbekistan (Tashkent) from 2012 to 2014.

The study was conducted with the Declaration of Helsinki, ethical approval of the National Committee of the Republic of Uzbekistan under the Ministry of Health of the Republic of Uzbekistan. Patients are acquainted and signed a written informed consent.

The average age of the patients was 57.8 ± 6.82 year. 19 of them women, 34 men. 27 patients entered to the main group [1] which received standard therapy in combination with intravenous fruc-tose-1,6-bisphosphate (FDP — Medexport, Italy). 26 patients in the control group [2] received standard treatment.

To patients of the main group the drug of FDP was administered intravenously in doses of 5 grams 1 times a day for 7 days. The infusion rate was 10 ml/min. 5 g. of the drug FDP was diluted in

50 ml. sterile applied solvent to obtain 10 % solution. The prepared solution was used once only, the remaining amount after the application had been eliminated. When adverse effects or allergic reactions the drug was discontinued.

Standard treatment consisted of the use of drugs that improve the microcirculation, anticoagulants, antiplatelet agents, neuroprotective agents, as well as drugs stabilizing blood glucose and blood pressure within 3 months.

The criterion for evaluating the effectiveness of therapy was to compare the visual acuity, visual fields, parameters of OCT and hemodynamics in the main vessels of the eye between the two groups.

Safety was evaluated by the number of adverse events during treatment. Adverse events were divided into two groups: a life-threatening events included in group 1, non-threatening in the 2nd group. For life-threatening events attributed conditions leading to disability or death of the patient. To a non-threatening life conditions include: dyspepsia, dizziness, headaches, feeling the tide, pulsation, "tingling" in the limbs, as well as allergic reactions.

The diagnosis OIS was based on the clinical and instrumental investigations and violations of hemodynamic parameters in the internal carotid and ophthalmic arteries, as well as clinical manifestations in the form of anterior ischemic neuropathy, central retinal artery occlusion, ischemic central retinal vein thrombosis and glaucoma. Patients with concomitant diseases of the eye, such as refractive errors, diabetic retinopathy, diseases of the inflammatory genesis of the optic nerve and retina, congenital abnormalities of the optic nerve and retina, as well as patients who underwent surgery on the internal carotid artery is not included in this study.

General examination of patients consisted of complaints, medical history, as well as the measurement of blood pressure, heart rate.

In all patients was performed a comprehensive ophthalmologic examination, including visometry, tonometry, computerized static perimetry, gonioscopy, biomicroscopy, fundus ophthalmoscopy. Special methods of investigation include ultrasound dopplerogra-phy of vessels of the organ of vision and the brachiocephalic trunk.

Visometry according to EN ISO 8596 (European standard) conducted on Snellens table (20/200) or Landolt rings. Tonometry was performed by the method of Goldman. Biomicroscopy of the eyeball conducted slit lamp company «Carl Zeiss». Fundus ophthalmoscopy were performed by ophthalmoscope «Heine» and fundus-camera «Carl Zeiss».

Computer static perimetry was performed using the perimeter of Humphrey Field Analyzer 740i (Carl Zeiss Meditec inc.) by programme central threshold test 30-2 and peripheral test 60-4. All results were recorded using a digital marking with the general analysis of indexes MD (mean deviation sensitivity of the retina) and PSD (pattern standard deviation). The distance between the test points was 6.

To estimate the parameters of the optic nerve (optic disk) all patients underwent examination optical coherence tomography (OCT) Cirrus HD — OCT (Zeiss, Spectral Domain Technology). Explored the area of the optic nerve (protocol ONH) and the area of the retina (RNFL).

Ultrasound examination with color Doppler mapping in 3D mode was performed by transpalpebral contact method using multi-ultrasonic instrument («VOLUSON 730 PROGE »). Doppler of the extracranial and intracranial segments of the main vessels of the brachiocephalic trunk was performed to analyze the state, caliber, patency and hemodynamics at the internal, external and common carotid arteries. In order to visualize blood flow in the ophthalmic artery, central retinal artery and its branches used ophthalmodopplerography.

The studies were conducted in the dynamics: before treatment, after treatment and 3 months after treatment.

All patients were randomized by the method of stratification by diagnosis, age, sex, visual function, and concomitant diseases.

Statistical Methods

We used a variational methods ofparametric and nonparametric statistics with the calculation of the arithmetic mean of the studied parameter (M), standard deviation (<<), standard error of the mean (m) and relative values (frequency, %). The statistical significance of the measurements by comparing the mean values was determined by Student's test (t) with the calculation ofthe probability of error (P) when checking normality of distribution (by the excess) and the equality of the population variance (F — Fisher's exact test). For statistically significant changes have taken level of confidence P < 0.05.

Results

According to the study in 12 patients the diagnosis OIS were based on central retinal artery occlusion combined with anterior ischemic optic neuropathy. In 11 patients was observed pseudoexfoliative syndrome in combination with occlusion of the central retinal artery and cataract. In 11 patients central retinal vein thrombosis combined with anterior ischemic neuropathy. In 10 patients occlusion of the central retinal artery developed in conjunction with anterior ischemic neuropathy and open-angle glaucoma. 9 patients had occlusion ofthe central retinal artery in combination with open-angle glaucoma and cataract. All patients with the above nosologies were evenly divided in the main and control groups for therapeutic measures.

In the main group visual acuity of patients before treatment was 20/340 on average. In the control group the visual acuity ofpatients before treatment was 20/320 on average.

Ophthalmoscopy of the fundus: optic disk was round shape in 25 (47.16 %) patients, oval — in 28 (52.83 %) patients, palely — pink in 7 (13.2 %) patients, pale — 43 (81.13 %) patients, hyper-emic — 3 (5.66 %) patients.

The boundaries of the optic disc are distinct in 3 (5.66 %), indistinct — in 17 (32.07 %), were not detected in 33 (62.26 %) patients. Papilledema was observed in 45 (84.9 %), peripapillary edema in 26 (49.05 %) cases. Narrowed artery in 47 (88.67 %), normal-caliber veins in 8 (15.09 %), the veins are narrowed in 31 (58.49 %), expanded in 14 (26.41 %) patients. In 23 (43.39 %) patients were visualized locuses of hemorrhages. Cotton-like locuses were observed in 17 (32.07 %) patients. Spontaneous pulsation of the arteries was observed in 23 (43.39 %) patients.

In 47 (88.67 %) patients in the OCT before treatment showed an increase in the thickness of the neuroretinal area, high edema ONH and peripapillary zone.

Analysis of the data computed perimetry showed an absolute scotoma in 23 (43.39 %), concentric narrowing of the visual field in 21 (39.62 %) patients. In the main group the mean deviation of retinal

sensitivity (MD) before treatment was--14.17 ± 1.29 dB (p < 0.05),

pattern standard deviation (PSD) — 6.24 ± 0.51 dB (p < 0.05). In

the control group before treatment MD was--13.93 ± 1.42 dB

(p < 0.05), PSD — 6.51 ± 0.49 dB (p < 0.05).

At Doppler ultrasound of the eyes revealed hemodynamically significant asymmetry of the velocity parameters of blood flow in the central retinal artery in 24 (45.28 %) patients, the posterior short ciliary arteries in 28 (52.83 %) in the ophthalmic artery in 42 (79.24 %) patients. In 47 (88.67 %) patients had a decrease in blood flow velocity parameters by ophthalmic artery with signs spasm of the peripheral arterioles.

In these patients the aforementioned changes combined with an increase of resistivity index by the central retinal artery and

posterior short ciliary arteries varying degrees, indicating that the deterioration of the blood supply in the organ ofvision.

In the main group before treatment hemodynamic parameters averaged: ophthalmic artery — Vmax 36.2 + 2.13 cm/s, Vmin 9.3 + 1.19 cm/s, RI 0.42 + 0.017 (p < 0.05); central retinal artery — Vmax 8.9 + 0.97 cm/s, Vmin 3.2 + 0.21 cm/s, RI 0.43 + 0.021; posterior short ciliary arteries — Vmax 12.4 + 0.78 cm/s, Vmin 5.3 + 0.13 m/s, RI 0.47 + 0.071, while in the control group: ophthalmic artery — Vmax 36.7 + 1.91 cm/s, Vmin 10.1 + 1.21 sm/s, RI 0.41 + 0.013; central retinal artery — Vmax 9.2 + 0.61 cm/s, Vmin 3.4 + 0.12 cm/s, RI 0.4 + 0.053; posterior short ciliary arteries — Vmax 12.1 + 0.81 cm/s, Vmin 5.1 + 0.19 cm/s, RI 0.46 + 0.091.

After the course of the treatment changes in the blood pressure and heart rate were not revealed.

In patients of both groups after treatment was a decrease in edema of the optic disc and peripapillary zones, areas of hemorrhage and cotton-like locuses.

After treatment in the main group visual acuity of patients in the affected eye improved by 32.8 % and amounted to 20/60, the intraocular pressure in the normal range. In the control group the visual acuity in the affected eye improved by 9.4 %, which was 20/125, intraocular pressure in the normal range.

After treatment in patients of the main group MD and PSD increased by 17.8 % and amounted: -9.29 ± 1.182 dB, 3.72 ± 0.176 dB (p < 0.05) respectively, while in the control group MD and PSD increased by 9.2 % and amounted: -11.18 ± 1.095 dB, 5. 38 ± 0.814 dB (p < 0.05) (table 1). On the computer perimetry absolute scotoma in dynamics decreased in both groups.

On optical coherence tomography papilledema and peripapillary zone in dynamics decreased in both groups.

After treatment in the main group noted improvement in blood flow in main arteries of eye by 16.57 %, after 3 month was 17.95 % from the initial level. In the control group hemodynamic parameters in main arteries of eye after treatment was improved by 7.2 %, after 3 month 7.4 % (tables 1, 2, 3).

In evaluating the safety of the FDP in both groups, adverse events that threaten the patient's life, was not registered. Events that do not threaten the life of the patient in the main group were 12: of these — dyspepsia in 4 patients, headaches in 3, dizziness in 3, feelings the tide in 2. In the control group recorded 13 cases: of these, dyspepsia in 3, headaches in 4, vertigo in 2, feelings the tide in 2, allergic reactions in the form of small rashes in the limbs in 2 patients. This indicate that is not statistically significant incidence of adverse events.

Discussion

Today the OIS is an urgent problem of ophthalmology, despite numerous works on the development of diagnostic and therapeutic measures performed in different countries.

The most frequent clinical manifestations of OIS were combination of anterior ischemic neuropathy, central retinal artery occlusion, ischemic central retinal vein thrombosis and glaucoma. In comparison with literature data the average age of patients was lower than 5.4 years.

In applying the FDP combined with comprehensive therapy in the main group resulted in increased of visual acuity by 32.8 %, parameters of retinal sensitivity by 17.8 %, reducing the area of scotomas compared with patients of the control group. This is confirmed by computed perimetry. Optical coherence tomography registered significant changes in the dynamics in patients of the main group — reducing the edema and restoration of RNFL and ONH. Recovery ofvisual function may have contributed neuroprotective activity of the drug FDP by a protective effect on nerve tissue, reducing the effects of hypoxic stress Karaca, Kilic, Yazici, Demir & Torre [3].

Should be noted that when using this drug in patients of the main group side effects such as changes in blood pressure and heart rate were not detected. In the works of Angel K. et al. 1997, noted anti-ischemic effect FDP without increasing blood pressure and heart rate, because the drug reduced the need for oxygen in ischemic tissues. FDP has been reported as the safe and effective drug Mar-chezani, Valerio, Dardes, Viglianti & Sanguinetti [5].

Considering the improvement of visual function and hemody-namic parameters in the main vessels of the eye in patients of the main group, as well as statistically insignificant indicators of adverse events in both groups, it may be noted about the safety and efficacy of the drug FDP. Conclusions

The use of standard therapy in combination with FDP in the treatment of ocular ischemic syndrome has a positive effect on the course of the disease, thereby, increase of visual acuity, a decrease in sectoral loss in vision fields, the positive dynamics OCT parameters, improving hemody-namic parameters at Doppler imaging in dynamics. Application FDP in patients with OIS is safe because, in patients of the main group were not recorded statistically significant indicators of adverse events and violations of the blood pressure and heart rate.

Clinical analysis of case histories of patients with typhoid held for the periods 1979 - 193 patients, 1997 - 61 patients, 2002 - 102 patients and for the period 2007-2010, 112 patients with typhoid fever. Also analyzed hospital records and the results of follow-up for typhoid carriers: 138 carriers in 1973 -1979 years, 52 — bacillicarriers in 1997-2002, and 70 persons in 2003-2010.

It was found that typhoid in Uzbekistan has undergone significant changes in 40 years, which showed an increase in the proportion of cases among children, n the prevalence of antibiotic-resistant pathogens of typhoid, in this regard — weighting of the clinical course of the disease, increasing the formation of acute and chronic bacterial carriage.

During the formation of the various outcomes of typhoid was the most essential dynamics of indicators such as erythrocyte sedimentation rate, immunoregulatory index, the level of antigen-binding lymphocytes, sensitized regarding the specific antigen S. typhi.

Keywords: typhoid, resistance to antibiotics, bacteria carriage.

Despite general decrease of typhoid morbidity, this rate in the Republic of Uzbekistan amounts to 0.3-0.2 per 100 000 of population per year [4]. As is known, in nowadays typhoid has been undergone substantial changes. This is the development of S. Typhi resistance to the most of commonly used antibiotics (including chloramphenicol) with both chromosome and plasmid strains resistance [1; 5]. Such factors as susceptibility ofpopulation to typhoid, alteration of the disease clinical course, increase of incidence of Salmonella typhi carriage are also of importance [3; 7].

The recent literature cites numerous data on various aspects of typhoid (etiology, epidemiology, diagnosis, pathogenesis, clinical course and etc.), but to date there had been no extended analysis of typhoid at the present stage in comparison with that of 30-40 years ago. Available publications reflect inadequate or not fully illuminate the nature of the clinical changes in typhoid as compared to the current and the manifestation of the disease in the past years. This was the subject of the present study.

Object of the study: to analyse dynamic development of typhoid and its outcomes in Uzbekistan for forty-year period.

Materials, methods and volume of study. We conducted a retrospective and prospective studies on the temper of the causative agent of typhoid, clinical course and outcomes of the disease in dynamics was carried out for forty-year period, taking into account the properties of S. typhi (1970-2010).

Case histories, outpatient's cards of patients with typhoid and convalescents from 1973 up to 2010 were analysed, as well as statistic reports of the Department of State Center of Sanitary and Epidemiological Surveillance for 1970-2010. 193 case histories for 1979, 61 — for 1997, 102 — for 2002 and 112 case histories for 2007-2010 were analysed. Diagnosis of typhoid was based on clinical data, results of bacteriological and/or serological (Vidal reaction, ELISA, etc) examination. Bacteriological examination was carried out by standard methods at bacteriological laboratories at the places of study (Samarkand region, Samarkand city, Kashka-Darya region, Tashkent city) and at microbiological department of Research Institute of epidemiology, microbiology and infectious diseases of the Ministry of Health of the Republic of Uzbekistan.

Detection ofantigen-binding lymphocytes (ABL) to S. typhi antigen was carried out by the method of Garib F. Yu. et al. (1995) [2].

T-lymphocytes and T-subsets for estimation of immunoregulatory index (II) were detected by the method of Novikov D. K. et al. in 2000 [6].

Outpatient's cards and results of dispensary observation of S.typhi carriers were analyzed: 138 individuals in 1973-1979, 52 in 1997-2002 and 70 carriers in 2003-2010.

Statistical analyses were performed using programs "Excel" and R-project.
