Objective: to study the clinical manifestations and effec- tiveness of treatment of patients with pulmonary tubercu- losis with different genotypes of M. tuberculosis. Materi­ als and methods. Clinical and microbiological data of 120 patients were stratified on the M. tuberculosis epidemic variants: subtypes of Beijing CC2 / W148, CC1, other sub- types of Beijing, and other genotypes other than Beijing (nonBeijing). The DNA of M. tuberculosis strains obtained were genotyped by RD 105/207 for Beijing genotype iden- tification. The CC2/W148 subtype was identified by the presence of a specific deletion in the kdpD gene, the CC1 subtype was done by the SNP in the pks17 gene. Results. It was found that in tuberculosis caused by the CC2/W148 subtype of the Beijing genotype, multiple and broad drug resistance occur in 87.5% of patients. The CC2/W148 ge- no type contributes to the chronization of the tuberculosis process, the formation of fibrous-cavernous tuberculo- sis. Miliary tuberculosis is more common (37.5%) among newly diagnosed patients with CC2/W148 than in other genotypes (15.7%), which is also associated with a high incidence of concomitant HIV infection (56.3%). Total lung tissue damage in patients with infiltrative tuberculosis is observed in 41.7% of patients with the CC2/W148 MBT subtype. The clinical cure rate in patients with CC2/W148 is significantly lower (18.7% compared to 47.4%) than in tuberculosis caused by other genotypes. Conclusion. The results obtained indicate the presence of clinical features of tuberculosis caused by the w148 / CC2 subtype of the Beijing genotype, and the expediency of further study of the clinical, radiological and microbio- logical characteristics of the tuberculosis process caused by MBT of different subtypes of the Beijing genotype and non-Beijing genotypes.

A case of lung damage in systemic lupus erythematosus (SLE) in a 33-year-old woman is described. This case is of clinical interest due to the complexity of diagnosis due to the fact that SLE is a disease with diverse clinical manifestations involving many organs and systems, which often makes it difficult to timely recognize the onset of the disease. SLE still remains a challenge and requires special attention to the patient s history, clinical and laboratory parameters of the patient, as well as specific immunological examinations.

Introduction. Liver damage can be a dangerous side effect of using isoniazid. Individual susceptibility to isoniazid in humans is dependent on the presence of N-acetyltransferase 2 allelic variants in genome. It was imperative to assess the effect of genetically determined isoniazid acetylation rate in terms of risk of developing isoniazid-induced hepatotoxicity, as well as prevention of potential hepatopathy, and improvement of tuberculosis chemotherapy safety. Aim. To study the effect of acetylation type on the incidence of isoniazid hepatotoxicity in residents of the Sakha Republic (Yakutia) with newly diagnosed pulmonary tuberculosis. Methods. The study included 112 patients with newly diagnosed pulmonary tuberculosis. Genotyping was performed using real-time polymerase chain reaction. The following single nucleotide polymorphisms were studied: rs1801280, rs1799930, rs1799931, rs1799929, rs1208, rs1041983. Hepatotoxicity was determined based on the results of clinical laboratory monitoring and using the criteria developed by the European Association for the Study of the Liver (2019). Results. Hepatotoxic reactions developed more often in slow acetylators (43.2%), compared to fast acetylators (20.7%) and intermediate acetylators (10.9%); p=0.002. Serum alanine aminotransferase activity was 5 or more times above the upper limit of normal activity in 37.8% of slow acetylators, and in 8.7% of intermediate acetylators; p=0.001. Clinical manifestations of isoniazid hepatotoxicity were observed more often in slow acetylators (29.7%), than in fast acetylators (3.4%); p=0.000. Conclusion. Slow acetylation type ought to be considered an important risk factor for developing isoniazid hepatotoxicity in patients with pulmonary tuberculosis.

Abstract Background Nitrofurantoin has been used to treat cystitis in women; however, data supporting its use in men is lacking. In addition, recent retrospective studies have challenged the manufacturer’s recommendation to avoid nitrofurantoin with creatinine clearances (CrCl) less than 60 mL/min. The purpose of this study is to compare the efficacy and safety of nitrofurantoin for the treatment of acute cystitis in male and female veterans with variable degrees of renal dysfunction. Methods A retrospective chart review was conducted in adult patients who received nitrofurantoin for acute cystitis in the outpatient setting between May 1, 2018 and May 1, 2019. The primary outcomes were rates of clinical cure as compared between males and females, and across various renal function groups (CrCl greater than 60 mL/min, 30 to 60 mL/min, and less than 30 mL/min) following treatment with nitrofurantoin. The secondary outcome was adverse event rates. Results A total of 446 patients were included with 278 females and 168 males. Overall clinical cure rate was 86.5% (n=386). Clinical cure rate did not vary between genders (p=0.0851) or CrCl ranges (p=1.0) as shown in the tables. Benign prostatic hyperplasia (BPH) was associated with decreased odds of clinical cure (OR 0.50 [95% CI 0.26-0.97], p=0.0404) in addition to cirrhosis (OR 0.22 [95% CI 0.06-0.91], p=0.0357). Adverse events occurred in 2% of patients and did not vary based on gender or renal function. RATES OF CLINICAL CURE Conclusion There was no statistically significant difference in clinical cure with nitrofurantoin between genders and various renal impairments. However, history of BPH and cirrhosis were associated with decreased efficacy. Subgroup analysis also revealed lower efficacy in males with CrCl greater than 60 mL/min versus females with similar renal function. This study adds to the growing body of literature suggesting that renal dysfunction with CrCl of 30 to 60 mL/min may not carry the risk of treatment failure and adverse effects previously associated with nitrofurantoin, but large randomized trials are needed to confirm these results.

BACKGROUND: Patients with hemochromatosis may suffer organ damage from iron overload, often with serious clinical consequences.OBJECTIVE: To assess prevalences of self-reported symptoms and clinical signs and conditions in persons homozygous for the hemochromatosis gene (HFE)mutation (C282Y) identified by screening.METHODS: Participants were adults 25 years of age or older enrolled in the Hemochromatosis and Iron Overload Screening (HEIRS) Study. C282Y homozygotes (n=282) were compared with control participants without theHFEC282Y or H63D alleles (ie, wild type/wild type; n=364).RESULTS: Previously diagnosed C282Y homozygotes and newly diagnosed homozygotes with elevated serum ferritin levels had higher prevalences of certain symptoms such as chronic fatigue (OR 2.8; 95% CI 1.34 to 5.95, and OR 2.0; 95% CI 1.07 to 3.75, respectively), and had more hyperpigmentation on physical examination (OR 4.7; 95% CI 1.50 to 15.06, and OR 3.7; 95% CI 1.10 to 12.16, respectively) and swelling or tenderness of the second and third metacarpophalangeal joints (OR 4.2; 95% CI 1.37 to 13.03, and OR 3.3; 95% CI 1.17 to 9.49, respectively) than control subjects. Joint stiffness was also more common among newly diagnosed C282Y homozygotes with elevated serum ferritin than among control subjects (OR 2.7; 95% CI 1.38 to 5.30). However, the sex- and age-adjusted prevalences of self-reported symptoms and signs of liver disease, heart disease, diabetes and most other major clinical manifestations of hemochromatosis were similar in C282Y homozygotes and control subjects.CONCLUSIONS: Some symptoms and conditions associated with hemochromatosis were more prevalent among C282Y homozygotes identified by screening than among control subjects, but prevalences of most outcomes were similar in C282Y homozygotes and controls in this primary care-based study.

ABSTRACTThe implication of coagulase-negative staphylococci in human diseases is a major issue, particularly in hospital settings wherein these species often act as opportunistic pathogens. In addition, some coagulase-negative staphylococci such asS. lugdunensishave emerged as pathogenic bacteria, implicated in severe infections, particularly, osteoarticular infections, foreign-body-associated infections, bacteremia, and endocarditis.In vitrostudies have shown the presence of several putative virulence factors such as adhesion factors, biofilm production, and proteolytic factors that might explain clinical manifestations. Taken together, the clinical and microbiological data might change the way clinicians and microbiologists look atS. lugdunensisin clinical samples.

Dislocations in the carpometacarpal joints of three-phalanx fingers are rare form of injury. Their clinical manifestations are often veiled by swelling, and radiographs in standard views provide little information, which leads to difficulty in diagnosis and a high incidence of unidentified dislocations in the primary treatment. The article describes the basic provisions of the diagnosis and treatment of this type of injury, a clinical case of surgical treatment of undiagnosed dislocations of II-V metacarpal bones in the acute period, and long-term results of treatment.

Congenital factor XIII (FXIII) deficiency is an extremely rare bleeding disorder (RBD) with estimated prevalence of one per 2 million in the general population. The disorder causes different clinical manifestations such as intracranial hemorrhage (ICH), recurrent miscarriage, umbilical cord bleeding, etc. High incidence of the disorder might be due to founder effect. To assess founder effect, haplotype analysis is an important step. For this purpose, suitable and reliable genetic markers such as microsatellites (Hum FXIIIA01 and HumFXIIIA02) and single nucleotide polymorphisms (SNP) are suggested. In the present study we tried to describe evaluation of founder effect in patients with congenital FXIII deficiency via haplotype analysis using suitable genetic markers.

ABSTRACT Ceftaroline, the bioactive metabolite of ceftaroline fosamil (previously PPI-0903, TAK-599), is a broad-spectrum cephalosporin with potent in vitro activity against multidrug-resistant gram-positive aerobic pathogens, including methicillin-resistant Staphylococcus aureus. A randomized, observer-blinded study to evaluate the safety and efficacy of ceftaroline versus standard therapy in treating complicated skin and skin structure infections (cSSSI) was performed. Adults with cSSSI, including at least one systemic marker of inflammation, were randomized (2:1) to receive intravenous (i.v.) ceftaroline (600 mg every 12 h) or i.v. vancomycin (1 g every 12 h) with or without adjunctive i.v. aztreonam (1 g every 8 h) for 7 to 14 days. The primary outcome measure was the clinical cure rate at a test-of-cure (TOC) visit 8 to 14 days after treatment. Secondary outcomes included the microbiological success rate (eradication or presumed eradication) at TOC and the clinical relapse rate 21 to 28 days following treatment. Of 100 subjects enrolled, 88 were clinically evaluable; the clinical cure rate was 96.7% (59/61) for ceftaroline versus 88.9% (24/27) for standard therapy. Among the microbiologically evaluable subjects (i.e., clinically evaluable and having had at least one susceptible pathogen isolated at baseline), the microbiological success rate was 95.2% (40/42) for ceftaroline versus 85.7% (18/21) for standard therapy. Relapse occurred in one subject in each group (ceftaroline, 1.8%; standard therapy, 4.3%). Ceftaroline exhibited a very favorable safety and tolerability profile, consistent with that of marketed cephalosporins. Most adverse events from ceftaroline were mild and not related to treatment. Ceftaroline holds promise as a new therapy for treatment of cSSSI and other serious polymicrobial infections.

Introduction.The given data of fundamental studies of apoptosis processes in B-cell lymphocytic leukemia (B-CLL) testifies about the complexity and variety of mechanisms affecting the kinetics of normal cells and tumor lymphocytes in this disease. It is important to study the severity of clinical manifestations of the disease depending on the expression of the genes that modulate apoptosis.The purposeof the study is to compare the activity of genes encoding apoptosis modulators, the cell cycle and cancer-testicular PRAME protein with clinical manifestations of the disease in primary patients with B-CLL.Materials and methods.The level of expression of the proapoptotic genes FAS, TRAIL, TNFR2, DR4/5 and DR3, as well as the HSP27, XIAP genes, blocking apoptosis was determined in 23 patients with newly diagnosed chronic B-CLL. In addition, expression of genes TP53 and P21 and cancer-testis gene PRAME are tested.Results.According to the multivariate regression analysis, the FAS gene expression in the onset of the disease had the greatest impact on the clinical characteristics of the disease. In this connection, the patients were divided into groups with normal (group) and low gene level (group II). A low level of FAS expression (Me 387 %) was associated with stage II disease (p = 0.03), a large number of lympho cytes (p = 0.001), fewer erythrocytes (p = 0.08), and a lower level of TNFR2 gene expression (p = 0.08), high level of expression of XIAP, HSP27, P21. Overall, the anti-apoptotic potential in Group II patients was higher, which was accompanied by more pronounced clinical manifestations of the disease.Conclusions.The increased anti-apoptotic potential of tumor lymphocytes in newly diagnosed B-CLL is accompanied by a larger tumor mass and greater clinical and hematological manifestation of the disease.

The aberrant accumulation of lipids in the plasma is associated with high incidence of atherosclerosis. Plasma lipids exhibit diurnal variations. Diurnal rhythms are controlled by two major transcription factors, Clock and Bmal1. Previously, we have shown that expression of a Clock mutant protein predisposes mice to hyperlipidemia and atherosclerosis. Here we show that the complete and liver-specific ablation of Bmal1 gene expression in Apoe -/- mice promotes hyperlipidemia and atherosclerosis. We observed that Bmal1 deficiency increases of microsomal triglyceride transfer protein (MTP) expression. Molecular studies indicated that Bmal1 deficiency decreases the expression of small heterodimer partner (SHP), a repressor MTP, to increase MTP expression and hepatic lipoprotein production. The effect of Bmal1 deficiency on MTP can be circumvented by the hepatic over expression of SHP. Over expression of SHP in the liver-specific Bmal1 deficient Apoe -/- mice reduced atherosclerosis and plasma lipids. These studies show that Bmal1 regulates hepatic lipoprotein production by regulating SHP. Deregulation of these circadian regulatory mechanisms and physiologic pathways predisposes mice to hyperlipidemia and atherosclerosis.
