A SEVERE CASE OF NON TYPHOIDAL SALMONELLA ASSOCIATED WITH MULTIPLE ORGAN DAMAGE- CASE STUDY AND LITERATURE REVIEW.

We report a severe case of a 25-year-old girl presented with complaints of weakness, diarrhoea, vomiting, pain in abdomen and hypotension at Infectious Diseases and Clinical Immunology Research Center. From history on 25 February till 29 February she was in India and on 1 march this problem started with watery diarrhoea followed by vomiting. She ate pizza with mushroom following which her condition worsened. Stool culture revealed salmonella nontyphi (nonthyphodal Salmonella)and this is leading cause for gastroenteritis, bacteremia and affects several other bodily system. Her condition deteriorated due to the development of ARDS (acute respiratory distress syndrome) and for this she was on mechanical ventilation. Vitec machine was performed, which identified Salmonella typhi murium. Our goal is to manage and treat this patient well by early diagnosis. She was given ceftriaxone, iv fluids and symptomatic treatment but due to resistance meropenem was started and the patient's condition improved. From serology there was no evidence of immunocompromised state so being a severe case of immunocompetent patient this case reflects the importance of timely diagnosis and management together with food safety practices in population. On follow up she was stable and discharged after 3 weeks. Future research studies need to be continued regarding newer strains, effective treatment strategies and diagnostics to prevent morbidity and mortality.

ENTEROHEMORRHAGIC ESCHERICHIA COLI LEADING TO HAEMOLYTIC UREMIC SYNDROME - CASE STUDY AND REVIEW.

Escherichia coli is a gram-negative bacillus and considered to be the normal pathogen of intestinal and extraintestinal manifestations depending upon the strain. A variety of strains exist that are responsible for causing myriads of clinical presentation. E.coli O157: H7 being the most common and severe bacterial pathogen is the leading cause of bloody diarrhea. EHEC (Enterohemorrhagic E.coli) is responsible for causing severe complications like HC (Hemorrhagic colitis). Herein, we present the case of a young girl with E.coli O157:H7 infection and review the related literature. A previously healthy 37-year-old female presented with bloody diarrhea, fever, headache, and lower abdominal pain. As per history she had eaten a hamburger, denied any recent travel and absence of inflammatory bowel disease or bloody stools in family history. Physical examination revealed normal vital signs and the physical findings were unremarkable except for severe abdominal pain. Her stool was hem-occult positive. The complete blood count was within normal limits except neutrophilia and leukocytosis. An abdominal ultrasound showed thickened bowel loops consistent with colitis. First week of her hospital course, she continued to have bloody diarrhea and severe abdominal pain. Her final stool submitted to the laboratory on day 7 was consistent with a blood clot, following her developed low urine output and hematuria, with a serum creatinine of 2.1 mg/dl on day 5. Her renal symptoms were treated with fluids. She was given supportive treatment, and her platelet count and hemoglobin were stabilized. In early stages of bloody diarrhea, parental hydration plays a major role in accelerating volume expansion. Rapid stool analysis for these bacteria can alert specialists to deal with severe complications like HUS.

AGE SPECIFIC CORRELATION PECULIARITIES OF THE DIAMETER AND DEFORMATION OF A HEALTHY HUMAN ERYTHROCYTE MEMBRANE.

The purpose of our research was to determine the interrelation peculiarities of erythrocyte membrane deformability and cell diameter in a practically healthy person, in different age groups. 60 volunteers were selected for this survey in 5 age groups: 1) 17-25, 2) 25-35, 3) 35-60, 4) 60-75, 5) 75-90. As a result of the study, it was determined that with aging the diameter of peripheral blood erythrocytes increases and an indicator of deformability, in contrary, decreases. The average diameter of erythrocytes in young people, is directly correlated with erythrocyte deformability, while in elderly people, negative correlation is revealed between erythrocytes diameter and their deformability. Decrease in membrane deformability, demonstrated in peripheral blood erythrocytes of elderly people, indicates the participation of different mechanisms in erythrocyte membrane deformity regulation, it might be related to age-related metabolic changes.
