Prognostic impact of main pulmonary artery to ascending aorta diameter ratio in patients with severe aortic stenosis underwent transcatheter aortic valve implantation.

BACKGROUND: Pulmonary hypertension (PH) and right ventricular dysfunction are poor prognostic predictors in patients underwent transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS). AIMS: The prognostic impact of the main pulmonary artery/ascending aorta diameter ratio (MPA/AOr), measured simply by computed-tomographic angiography (CTA), was investigated in this patient group. METHODS: A total of 374 retrospectively evaluated patients (mean age 78.1 ± 8.4 years, 192 [51.3%] females) who underwent TAVI for severe AS were included. MPA/AOr was measured on preprocedural CTA in all patients and the effect of this measurement on the presence of PH, in-hospital and 2-year-overall long-term mortality was investigated. RESULTS: The presence of PH was defined as a systolic pulmonary artery pressure (sPAP) >42 mmHg measured by echocardiography. According to multivariate-logistic-regression analysis, MPA/AOr (adjusted [Adj] odds ratio [OR]: 1.188, confidence interval [CI] 95% [1.002-1.410], p = 0.048), tricuspid annular plane systolic excursion (TAPSE) (adj OR:0.736, CI 95% [0.663-0.816], p < 0.001) and left atrial diameter (adj OR:1.051, CI 95% [1.007-1.098], p = 0.024) were identified as independent predictors of PH. In addition, a statistically significant correlation was found between MPA/AOr and TAPSE (r: -0.283, p < 0.001). Furthermore, MPA/AOr was found to be an independent predictor of both in-hospital (adj OR:1.434, CI 95% [1.093-1.881], p = 0.009) and 2-year long-term (adj OR:1.518, CI 95% [1.243-1.853], p < 0.001) mortality in multivariate analysis including TAPSE, STS score and sPAP. In the 2-year Kaplan-Meier survival probability analysis, an MPA/AOr >0.86 was found to have a hazard ratio of 3.697 (95% CI: 2.341-5.840), with a log-rank p < 0.001. CONCLUSION: MPA/AOr, which can be measured simply by CTA, may be useful as an indicator of the presence of PH and poor prognosis in patients planned for TAVI for severe AS.

Proton pump inhibitors with calcium acetate on serum phosphorus levels in hemodialysis patients.

Background: The increase in serum phosphorus level is an independent risk factor for mortality in patients with chronic renal failure or undergoing dialysis due to end-stage renal disease. Proton pump inhibitors (PPI) are the general name given to agents used to suppress stomach acid. In this study, the clinical benefit of using PPIs in addition to drugs used for phosphorus control was investigated. Methods: 153 patients with end-stage renal disease were included in the study. The data of the patients who had been on hemodialysis for at least 6 months and using calcium acetate for at least 1 month were recorded in the SPSS 21 program. The patients were analyzed in two groups according to whether they used PPI or not. Anamnesis, patient follow-up, laboratory, and treatment forms collected from hemodialysis centers were used. Results: Of the 153 patients in the study, 49% were males and the mean age was 65.11±11.23. The mean duration of patients on dialysis was 48.5 months. Hypertension was found to be the most common comorbidity with 75.8% prevalence among the patients. The mean phosphorus levels of the patients using calcium acetate together with PPI were found to be approximately 1.2 mg/dl lower (p= 0.000). Conclusion: It should be taken into account that the use of PPI together with calcium acetate, which is still common as a phosphorus binder in developing countries, can contribute to controlling phosphorus levels.

Leptospirosis during the COVID-19 pandemic: a case report.

Since SARS-CoV-2 disease (COVID-19) has been labeled as a pandemic, it took the spotlight in the differential diagnosis for patients presenting with acute respiratory and systemic symptoms. Leptospirosis is one of the most common zoonoses in the world, yet it is mainly a disease of differential diagnosis for places that do not have it as an endemic. Due to the high burden of COVID-19 on the healthcare field, patients suffering from other infections may have been inadvertently neglected. COVID-19 infection can mimic other infectious diseases and can confuse physicians in their search for a confirmatory diagnosis. Nonetheless, it is very crucial to broaden the differential diagnosis and keep diseases like leptospirosis within the differential diagnosis despite its rarity, especially in patients presenting with unexplained systemic infectious symptoms. This is a unique case of a patient who presented with dyspnea, jaundice and change in urine color who was suspected to be COVID-19 positive. After a detailed investigation, the patient was diagnosed with leptospirosis instead of COVID-19 and was treated with plasmapheresis and antibiotics accordingly.

Predictive role of FAR ratio in COVID-19 patients.

OBJECTIVE: No effective treatment has yet been found for SARS-Cov-2, which caused a pandemic outbreak in 2019. It is crucial to detect the progression of COVID-19 in patients as early as possible. Fibrinogen to albumin ratio (FAR) has been used as a new inflammatory marker. We aimed to find out whether the use of the FAR as a predictor of mortality in COVID-19 patients provides clinical benefit. MATERIALS AND METHODS: Data from 590 patients with COVID-19 from March 15, 2020 to January 15, 2021 in medicine wards and intensive care units (ICU) were retrospectively analysed. Demographic data and other laboratory markers were collected from the electronic medical records. Relationship between FAR was investigated between patients in the survivor/non-survivor patients. FINDINGS: The mean FAR levels in patients who were non-survivor was 24.44 ± 30.3 (n = 272 and 11.29 ± 6.29 (n = 275) (P = .000) in patients survivor COVID-19 infection. In ROC curve for FAR, the threshold FAR that may pose a risk for mortality was determined as 13.84 ((AUC: 0.808 (0.771-0.844)); 74.9% sensitivity, 74.6% specificity; P = .000)). RESULT: As a result of this study, increased FAR were found to be important markers in determining the mortality levels in COVID-19 patients.

Isolated Intestine Transplantation for Autoimmune Enteropathy: A Case Report.

Autoimmune enteropathy is a rare disease characterized by chronic watery diarrhea, weight loss, and immune-mediated injury of the enterocolic mucosa. The clinicopathologic findings of this disease are variable, and timely diagnosis is challenging. It is usually managed medically. If medical management fails, surgical intervention is considered. This is a case report of a patient with autoimmune enteropathy mimicking collagenous enterocolitis. A 55-year-old man developed intestinal failure that manifested as profuse watery diarrhea, electrolyte disturbances, and weight loss. Initially, he was diagnosed with collagenous enterocolitis based on pathologic findings. Medical interventions were started, but the patient failed to show improvement. At 13 months after the onset of the disease, he was listed for isolated intestine transplantation (IITX) for intestinal failure. A healthy donor graft became available. IITX with chimney colostomy was performed. Based on the pathologic findings of the excised native small intestine, the patient was diagnosed with severe autoimmune enteropathy. The postoperative course was uneventful. By the third postoperative week, a full diet was tolerated and parenteral nutrition (PN) was weaned to end. He was discharged on postoperative day 34. Since discharge, he has been off PN, remaining on an enteral diet. This case is the first reported IITX performed on a patient with severe autoimmune enteropathy that was both curative and lifesaving. The present case confirms that IITX promptly restores gastrointestinal absorption in medically refractory autoimmune enteropathy. This observation provides clinicians with an effective treatment option in this challenging group of patients.

Effect of Systemic Infliximab Therapy in Patients with Sjögren's Syndrome.

OBJECTIVES: To investigate the effect of systemic infliximab therapy on tear function tests and the ocular surface in patients with Sjögren's syndrome secondary to various autoimmune diseases. MA­TE­RI­ALS AND MET­HODS: This prospective study included 22 eyes of 22 patients with Sjögren's syndrome who began treatment with systemic infliximab. Tear film break-up time (TBUT), anesthetized Schirmer's 1 test, fluorescein staining test, and Ocular Surface Disease Index (OSDI) scores were recorded before treatment and in the 3rd and 6th months of treatment. RE­SULTS: In the 3rd month of infliximab therapy, no significant changes were observed in Schirmer's values, TBUT, fluorescein staining, or OSDI scores (p=0.260, p=0.357, p=0.190 and p=0.07, respectively). In the 6th month of infliximab therapy, no significant changes were observed in TBUT, fluorescein staining, Schirmer's value or OSDI scores (p=0.510, p=0.320, p=0.220 and p=0.344, respectively). CONCLUSION: Infliximab therapy, which is commonly used in systemic autoimmune diseases such as rheumatoid arthritis, Crohn's disease, ulcerative colitis, and ankylosing spondylitis, did not show a positive effect on ocular surface and tear function tests.

Absence of the SLC22A12 gene mutation in Turkish population with primary gout disease.

The aim of the study was to examine whether SLC22A12 gene mutations might be influenced in primary gout disease. We included 32 patients with diagnosis of primary gout disease and 100 healthy volunteers. DNA was purified from peripheral blood, and all exons of the SLC22A12 gene were sequenced. We did not find any mutations in the SLC22A12 gene in all of the patients, but found 5 polymorphisms in exons 1 (g.T258C, g.C246T), 2 (g.C1246T) and 8 (g.T8011C) and in intron 9 (g.C8577T). However, we have not found any significant differences in the frequency of the individual genotypes between patients with primary gout disease and control group. In addition, the polymorphisms were not associated with hyperuricemia in our patients with primary gout disease. There was no previously reported mutation/polymorphisms of SLC22A12 gene in Turkish population. Our study is the first one in Turkish population and suggests that there is no association between primary gout disease and SLC22A12 gene polymorphisms. Sequence changes in the promotor and intronic regions of SLC22A12 gene should be investigated further with larger case groups.

Positiveness of purified protein derivatives in rheumatoid arthritis patients who are not receiving immunosuppressive therapy.

In recent years, biological agents have emerged as the most popular drugs for the treatment of rheumatoid arthritis (RA). The most frightening side effects of biological agents are infections, with tuberculosis being the leader. On account of the fact that biological agents have been used widespread, a number of algorithms have been developed to search latent tuberculosis. Among these algorithms, the most popular is the purified protein derivatives (PPD) test which is based upon late sensitivity reaction. The objective of this trial is to investigate the relevance of PPD response for the disease in RA patients. A total of 149 subjects (80 patients, 69 healthy), 35 RA patients who have not been treated before, 23 RA and 22 AS patients who are candidates for biological agents and being treated with immunosuppressive drugs, and 69 healthy subjects, have been included in this trial. Swelling joints, number of tender joints, visual analog scale, erythrocyte sedimentation rate, C-reactive protein, and rheumatoid factor were recorded. PPD was performed using the Mantoux method and was measured 72 h later. Statistically significant lower PPD values were determined in untreated RA patients compared to PPD values of treated RA and AS patients and healthy subjects. No correlation was determined between disease activity score 28 activity and PPD values in untreated and treated groups. Similarly, there was no correlation between acute phase reactants and PPD. Lower PPD responses in patients not being treated with immunosuppressive are due to the disease itself, rather than to the drugs being used. It is also important to interpret PPD results in early RA patients with suspicion, when it is intended to start anti tumor necrosis factor therapy.

Diagnostic value and clinical significance of anti-CCP in patients with advanced rheumatoid arthritis.

OBJECTIVES: To investigate the prevalence of anticyclic citrullinated peptide (anti-CCP) in patients with advanced rheumatoid arthritis (RA) and to compare it with those in control subjects. Further, to study the relation between the anti-CCP and the disease activity parameters in these patients. PATIENTS AND METHODS: Seventy-six RA patients who had a mean disease duration of 9.8 years were included. Eighty-three age-matched non-RA volunteers were enrolled as the control group. Disease duration, duration of morning stiffness, swollen and tender joint counts, hand deformity, patient's assessment of pain, anti-CCP, rheumatoid factor (RF) and acute phase proteins were evaluated. The functional disability was also assessed with the Modified Health Assessment Questionnaire (HAQ). RESULTS: Thirty-seven sera (48.7%) in the patient group and one serum (1.2%) in the control group were positive for anti-CCP. RF was positive in 45% of the RA cases and in 5% of controls. Sensitivity and specificity of anti-CCP reactivity for RA were 49.0% and 99.0%, respectively. HAQ score and duration of morning stiffness were found to be significantly associated with anti-CCP positivity. Disease duration, swollen joint count and anti-CCP positivity were the most important variables predicting hand deformity. CONCLUSION: The prevalence, sensitivity and specificity of anti-CCP in patients with advanced RA were found to be similar to those reported in patients with early disease. Anti-CCP was significantly associated with some parameters of both disease activity and severity. Anti-CCP might be a useful parameter in clinical evaluation of patients with advanced RA.

Factors affecting one year mortality and functional outcome after first ever ischemic stroke in the region of Antalya, Turkey (a hospital-based study).

In order to establish good health politics for stroke survivors, regional differences in factors affecting the outcome of patients have to be known. For this purpose we investigated factors affecting 1 year mortality and functional outcome in patients with first-ever-in a lifetime stroke in the region of Antalya, Turkey. One-hundred and forty-seven patients with a first ever stroke were included and followed up for at least one year. The modified Rankin Scale was used for evaluation of handicap. Several factors known to affect prognosis such as demographic features, socioeconomic status, stroke subtype, neurological findings and stroke risk factors were compared between patients who died during follow-up and survivors. Of the 147 patients 35 (23.8%) died during the course of the study. Multivariate logistic regression analysis showed that only illiteracy, being single or widowed and presence of urinary incontinence were significant predictors of being dead at the end of 1 year. In the survivors factors independently affecting dependence at the end of one year were age, presence of coma on admission and urinary incontinence. Our results suggest that not only stroke severity but also socioeconomic variables are important in determining the prognosis of stroke patients.
