Characteristics of our hypoxemic COVID-19 pneumonia patients receiving corticosteroids and mortality-associated factors.

BACKGROUND: COVID-19 is a disease associated with diffuse lung injury that has no proven effective treatment yet. It is thought that glucocorticoids may reduce inflammation-mediated lung injury, disease progression, and mortality. We aimed to evaluate our patient's characteristics and treatment outcomes who received corticosteroids for COVID-19 pneumonia. METHODS: We conducted a multicenter retrospective study and reviewed 517 patients admitted due to COVID-19 pneumonia who were hypoxemic and administered steroids regarding demographic, laboratory, and radiological characteristics, treatment response, and mortality-associated factors. RESULTS: Of our 517 patients with COVID-19 pneumonia who were hypoxemic and received corticosteroids, the mortality rate was 24.4% (n = 126). The evaluation of mortality-associated factors revealed that age, comorbidities, a CURB-65 score of ≥ 2, higher SOFA scores, presence of MAS, high doses of steroids, type of steroids, COVID-19 treatment, stay in the intensive care unit, high levels of d-dimer, CRP, ferritin, and troponin, and renal dysfunction were associated with mortality. CONCLUSION: Due to high starting and average steroid doses are more associated with mortality, high-dose steroid administration should be avoided. We believe that knowing the factors associated with mortality in these cases is essential for close follow-up. The use of CURB-65 and SOFA scores can predict prognosis in COVID-19 pneumonia.

Characteristics of hospitalised COVID-19 patients and parameters associated with severe pneumonia.

BACKGROUND: After the first case of coronavirus disease 2019 (COVID-19) was reported in China in December 2019, it caused a global pandemic, including Turkey. OBJECTIVES: The aim of this study was to analyse the characteristics of hospitalised COVID-19 patients and assess the parameters related to severe pneumonia. METHODS: Included in the study were hospitalised COVID-19 patients with positive naso-oropharyngeal swabs. Patients' demographics, admission symptoms, laboratory and radiological findings were recorded retrospectively. RESULTS: Of 1013 patients, 583 were males (57.6%) and 430 were females (42.4%), with a mean age of 53.7 ± 17.9. More than half of the patients had at least one comorbidities, the most common of which were hypertension and diabetes mellitus. Cough (59.8%), fatigue (49.5%) and fever (41.2%) were the most common presenting symptoms. Of the hospitalised COVID-19 patients, 84.9% had pneumonia and 83.5% had typical radiological COVID-19 appearances (94.5%: ground-glass areas). The most common laboratory findings were high C-reactive protein (CRP) (73.6%) and lactate dehydrogenase (LDH) (46.2%) levels, as well as lymphopenia (30.1%). Severe pneumonia was present in 28.1% of COVID-19 patients. Multivariate logistic regression analysis indicated that advanced age, hypotension, anaemia and elevated CRP and LDH serum levels were independent risk factors for the severity of COVID-19 pneumonia (P = .011, .006, .017, .003 and .001, respectively). CONCLUSION: This study, as one of the first multicentre studies about characteristics of COVID-19 in Turkey, may guide about disease-related parameters and severity of pneumonia. Age, blood pressure, complete blood count and routine biochemical tests (including CRP and LDH) would appear to be important parameters for the evaluation of the severity of COVID-19 pneumonia.

The relationship of extent of initial radiological involvement with the need of intensive care, mortality rates, and laboratory parameters in Covid-19

Background/aim: It is very important for the efficient use of limited capacity and the success of treatment to predict patients who may need ICU with high mortality rate in the Covid-19 outbreak. In our study, it was aimed to investigate the value of the radiological involvement on initial CT in demonstrating the ICU transfer and mortality rate of patients. Materials and methods: All PCR-positive patients were included in the study, whose CT, PCR, and laboratory values were obtained simultaneously at the time of first admission. Patients were divided into 4 groups in terms of the extent of radiological lesions. These groups were compared in terms of intensive care transfer needs and Covid-related mortality rates. Results: A total of 477 patients were included in the study. Ninety of them were group 0 (no lung involvement), 162 were group 1 (mild lesion), 89 were group 2 (moderate lesion), and 136 were group 3 (severe lung involvement). A significant relationship was found between the extensiveness of the radiological lesion on CT and admission to intensive care and mortality rate. As the initial radiological involvement amounts increased, the rate of ICU transfer and mortality increased. The mortality rates of the groups were 0%, 3%, 12.3%, and 12.5%, respectively, and the difference was significant (p < 0.001). Similarly, the ICU transfer rates of the groups were 2.2%, 5.6%, 13.5%, and 17.7%, respectively, and the difference was significant (p < 0.001). Conclusion: In conclusion, in our study, the strong relationship between the initial radiological extent assessment and the need for intensive care and mortality rates has been demonstrated, and we believe that our results will make a significant contribution to increase the success of the health system in predicting patients who may progress, helping clinicians and managing pandemics.

The relationship between serum bicarbonate, pH level and sleep quality in haemodialysis patients: A cross-sectional study from Turkey.

OBJECTIVE: To investigate the relationship of blood pH and bicarbonate levels with sleep disorders in patients with end-stage renal disease. METHODS: The cross-sectional study was conducted at Kocaeli Derince Health Practice and Research Center, Kocaeli, Turkey, in July 2015, and comprised stable haemodialysis patients aged over 18 years who had undergone at least 3 months of treatment. The Pittsburgh sleep quality index was used to assess sleep quality, and the Epworth sleepiness scale was used to assess sleepiness. Blood urea nitrogen levels were measured to determine dialysis success. SPSS 17 was used for data analysis. RESULTS: Of the 62 patients, 22(35.4%) were good sleepers, while 40(65.6%) were bad sleepers, and 11(17.7%) had excessive daytime sleepiness. There was no significant difference between poor and good sleepers with respect to venous pH (p=0.197) and bicarbonate (p=0.305) levels. Also, the two levels did not differ significantly between patients with routine or excessive daytime sleepiness (p>0.05). Patients with excessive daytime sleepiness had significantly lower calcium (p=0.046) and higher creatinine (p-0.014) levels and were older (p=0.01). Age was the only independent predictor of both the index and the scale scores (p<0.05 each). CONCLUSIONS: Sleep disorders and sleepiness were found to be high in haemodialysis patients and there was a strong correlation between sleep disturbance and age. There was no correlation of either state with patients' bicarbonate or venous pH values.

Comparison of oxidant/antioxidant balance in COPD and non-COPD smokers.

BACKGROUND/AIM: Oxidative stress plays an important role in the pathogenesis of chronic obstructive pulmonary disease (COPD). Smoking is the leading source of oxidants in lungs. However, it is currently unknown why some individuals are more resistant to the detrimental effects of smoking and do not develop COPD. The aim in this study is to measure and compare the oxidant/antioxidant balance between in non-COPD individuals who smoke and COPD patients who smoke. MATERIALS AND METHODS: Included in the study were 137 patients with COPD and 102 healthy individuals. Participants were divided into groups as COPD patients (former and current smokers), non-COPD individuals who smoke and non-smokers healthy persons. In the following stage, the total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI) levels were measured in serum for all participants. RESULTS: In the current-smoker COPD group, the level of oxidant status were significantly higher than the former-smoker COPD group (p < 0.001). Similarly, oxidant levels were significantly high in current-smoker healthy group than never smoker healthy group. According to these results TOS was associated with especially smoking status rather than COPD. Antioxidant status were similar between former-smoker COPD group and current-smoker COPD group. The antioxidant levels were found significantly low in current-smoker COPD patients, compared to the current-smoker non-COPD individuals (p = 0.007). Nevertheless, no significant difference was found in OSI levels between two groups. Briefly, high TOS and OSI values were correlated with only smoking, independently from COPD. CONCLUSION: It was concluded that there are complex pathogenetic mechanisms, including genetic and individual variations other than oxidant/antioxidant balance, involved in the development of smoking-related COPD. TOS and OSI values are not predictive parameters for the development of COPD, but high level of TAS in non-COPD smokers is promising for future studies.

Carotid intima-media thickness in chronic obstructive pulmonary disease and survival: A multicenter prospective study.

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is associated with increased cardiovascular morbidity and mortality. Carotid intima-media thickness (CIMT) is a noninvasive method assessing atherosclerosis. OBJECTIVE: It was aimed to determine relationship and survival between COPD and CIMT. METHODS: CIMT was measured using Doppler ultrasound (USG) in 668 stable COPD patients at 24 centers. Patients were followed-up for 2 years. RESULTS: There were 610 patients who completed the study. There were 200 patients CIMT with <0.78 mm (group 1), and 410 with CIMT ≥ 0.78 mm (group 2). There was a significant difference at the parameters of age, gender, smoking load, biomass exposure, GOLD groups and degree of airway obstruction (FEV1) between groups 1 and 2. Our results revealed positive correlations between mean CIMT and age, smoking load (pack-years), biomass exposure (years), exacerbation rate (last year), duration of hypertension (years) and cholesterol level; negative correlations between CIMT and FEV1 (P < 0.05). According to logistic regression model, compared with group A, risk of CIMT increase was 2.2-fold in group B, 9.7-fold in group C and 4.4-fold in group D (P < 0.05). Risk of CIMT increase was also related with cholesterol level (P < 0.05). Compared with infrequent exacerbation, it was 2.8-fold in the patients with frequent exacerbation (P < 0.05). The mean survival time was slightly higher in group 1, but not significant (23.9 vs 21.8 months) (P > 0.05). CONCLUSION: This study is the first regarding CIMT with combined GOLD assessment groups. It has revealed important findings supporting the increase in atherosclerosis risk in COPD patients. We recommend Doppler USG of the carotid artery in COPD patients at severe stages.

Desquamative interstitial pneumonia: Risk factors, laboratory and bronchoalveolar lavage findings, radiological and histopathological examination, clinical features, treatment and prognosis.

Desquamative interstitial pneumonia is a type of smoking-associated major idiopathic interstitial pneumonia, which is characterized by accumulation of alveolar macrophages in alveolar lumens and septa and develops secondary to mainly active or passive exposure to cigarette smoke. Desquamative interstitial pneumonia mostly occurs in male smokers in association with non-specific symptoms responsive to steroid therapy and has a better prognosis than usual interstitial pneumonia. To date, no large-scale clinical studies have been performed on desquamative interstitial pneumonia patients. Factors responsible for the scarcity of data on the clinical course of this condition include the retrospective nature of the available information as well as its rare occurrence. Despite this, a general consensus exists as to the nature of its symptoms, association with smoking, age and gender distribution, findings of respiratory function tests, steroid responsivity and mortality. The objective of the present review article was to report on desquamative interstitial pneumonia and to describe its etiology, risk factors and clinical features, as well as the laboratory, bronchoalveolar lavage, radiological and histopathological findings, and the treatment and prognosis of affected patients.

Factors affecting TST level in patients undergoing dialysis: a multicenter study.

INTRODUCTION: The risk of TB is increased in patients with chronic kidney disease (CKD) when compared with individuals with normal renal function. We aimed to determine tuberculin skin test (TST) response and the factors which might affect the response in patients with CKD undergoing dialysis in this study. METHODS: The purified protein derivative solution was administered to the patients and the diameter of induration was measured. Additionally, the age, gender and smoking status of the patients were interrogated. Comorbidities were recorded both by patients' self-reports and data from the hospital files. The number of Bacille Calmette-Guerin (BCG) scars was recorded by checking both shoulders. FINDINGS: The study was conducted with a total of 371 patients (194 men and 177 women). The mean age was 60.09 ± 15.88, TST was 6.99 ± 6.9, duration of dialysis was 4.44 ± 4.5 (3.8-0.1,24). A total of 229 patients have comorbodities (61.7%, the most frequent was hypertension). Logistic regression model was performed. Gender, vitamin D treatment and high parathormone (PTH) levels remained in the final stage of the analysis and vitamin D intake and PTH levels were detected to be statistically significant (P = 0.002, 0.007, respectively). DISCUSSION: This study is the first study which showed a correlation between TST negativity and increased PTH levels and receiving vitamin D treatment. Starting from this point, it was concluded that PTH may suppress the immune system and especially cellular immunity.

Influenza and Pneumonia Vaccination Rates and Factors Affecting Vaccination among Patients with Chronic Obstructive Pulmonary Disease.

BACKGROUND: Influenza and pneumococcal vaccinations are recommended in chronic obstructive pulmonary disease patients to decrease associated risks at all stages. Although the prevalence of chronic obstructive pulmonary disease is high in our country, as previously reported, vaccination rates are low. AIMS: To assess the vaccination rates of chronic obstructive pulmonary disease patients and factors that may affect these. STUDY DESIGN: Multi-centre cross-sectional study. METHODS: Patients admitted to the chest diseases clinics of six different centres between 1 February 2013 and 1 January 2014 with a pre-diagnosis of Chronic obstructive pulmonary disease according to the Global initiative for chronic obstructive lung disease criteria, who were in a stable condition were included in the study. The survey, which included demographic characteristics, socio-economic status, severity of disease and vaccination information, was first tested on a small patient population before the study. The survey was completed by the investigators after obtaining written informed consent. RESULTS: The average age of the 296 included patients was 66.3±9.3 years and 91.9% were male. Of these, 36.5% had the influenza vaccination and 14.1% had the pneumococcal vaccination. The most common reason for not being vaccinated was 'no recommendation by doctors': 57.2% in the case of influenza vaccinations, and 46.8% in the case of pneumococcal vaccinations. Both vaccination rates were significantly higher in those patients with comorbidities (influenza vaccination p<0.001; pneumococcal vaccination p=0.06). There was no significant correlation with age, gender, smoking and severity of disease (p>0.05). Vaccination rates were significantly higher in those with a white-collar occupation and higher education level, and who presented to a university hospital (p<0.001). CONCLUSION: Medical professionals do not request vaccinations as often as the International Guidelines suggest for chronic obstructive pulmonary disease patients. Awareness of the importance of these vaccinations among both doctors and patients needs to be addressed.

What are the Prevalence of Abdominal Aortic Aneurysm in Patients with Chronic Obstructive Pulmonary Diseases and the Characteristics of These Patients?

OBJECTIVE: To determine the prevalence of abdominal aortic aneurysm (AAA) in patients with chronic obstructive pulmonary disease (COPD) and to assess the characteristics of these patients. MATERIALS AND METHODS: Stable COPD patients (age, >40 years) were included in the study between January 2014 and June 2014. Patients with acute exacerbations and a previous lung resection were excluded. Data regarding demographic characteristics were recorded. The modified Medical Research Council (mMRC) dyspnea scale was used to assess the severity of breathlessness. The COPD Assessment Test (CAT) was performed. Abdominal aortic diameter was measured using abdominal ultrasonography (AUS), and AAA was diagnosed as an aortic diameter of ≥30 mm at the renal artery level. RESULTS: In total, 82 patients were examined. AAA was detected in five (6.1%) patients. Diabetes mellitus, hypertension, and coronary artery disease were present in four patients with AAA. The average mMRC score was 3.2±0.4, and the mean CAT score was 18.4±6.0. Aneurysmal diameter was >50 mm in four patients and 37 mm in one patient. Statistically significant differences were found between patient with AAA and those without AAA with respect to the mean abdominal aortic diameters at the renal artery and iliac artery levels (p=0.012 and 0.002, respectively). CONCLUSION: Our findings suggest that AAA is associated with COPD, with a prevalence rate of 6.1%. AAA is usually asymptomatic until a clinical status of rupture, which is associated with a higher mortality risk. Early diagnosis of AAA is lifesaving. In COPD patients, AAA might be easily determined using AUS, which is a noninvasive and relatively cheap procedure.

Clinical factors and comorbidities affecting the cost of hospital-treated COPD.

PURPOSE: We aimed to assess the effects of comorbidities on COPD costs and to investigate the relationship between comorbidities and clinical variables. PATIENTS AND METHODS: All patients hospitalized with a diagnosis of COPD exacerbation between January 1, 2014, and December 31, 2014, at all state hospitals of Aydin province, a city located in the western part of Turkey, were included in this study. The costs examined in the study pertained to medications, laboratory tests, hospital stays, and other treatment-related factors, such as consumption of materials, doctor visits, and consultation fees. RESULTS: A total of 3,095 patients with 5,237 exacerbations (mean age, 71.9±10.5 years; 2,434 males and 661 females) were evaluated. For 880 of the patients (28.9%), or 3,852 of the exacerbations (73.1%), at least one comorbid disease was recorded. The mean cost of each exacerbation was $808.5±1,586, including $325.1±879.9 (40.7%) for hospital stays, $223.1±1,300.9 (27.6%) for medications, $46.3±49.6 (0.9%) for laboratory expenditures, and $214±1,068 (26.5%) for other treatment-related factors, such as consumption of materials, doctor visits, and consultation fees. The cost of each exacerbation was $1,014.9 in patients with at least one comorbidity, whereas it was $233.6 in patients without comorbidity (P<0.001). Age >65 years, female gender, hospitalization in an intensive care unit, invasive or noninvasive mechanical ventilation, and a long duration of hospitalization were all found to be significant factors in increasing total costs during the exacerbations requiring hospitalization (P<0.05 for all). CONCLUSION: Comorbidities have an important role in the total costs of acute exacerbations of COPD. Strategies for the prevention, diagnosis, and effective management of comorbidities would decrease the overall financial burden associated with acute exacerbations of COPD.

Serum Uric Acid Levels and Uric Acid/Creatinine Ratios in Stable Chronic Obstructive Pulmonary Disease (COPD) Patients: Are These Parameters Efficient Predictors of Patients at Risk for Exacerbation and/or Severity of Disease?

BACKGROUND Serum uric acid (sUA) levels were previously found to be correlated with hypoxic states. We aimed to determine the levels of sUA and sUA/creatinine ratios in stable COPD patients and to evaluate whether sUA level and sUA/creatinine ratio can be used as predictors of exacerbation risk and disease severity. MATERIAL AND METHODS This cross-sectional study included stable COPD patients and healthy controls. The sUA levels and sUA/creatinine ratios in each group were evaluated and their correlations with the study parameters were investigated. ROC analyses for exacerbation risk and disease severity were reported. RESULTS The study included 110 stable COPD patients and 52 healthy controls. The mean sUA levels and sUA/creatinine ratios were significantly higher in patients with COPD compared to healthy controls. The most common comorbidities in COPD patients were hypertension, diabetes, and coronary artery disease. While sUA levels were significantly higher in patients with hypertension (p=0.002) and malignancy (p=0.033), sUA/creatinine ratios was higher in patients with malignancy (p=0.004). The ROC analyses indicated that sUA/creatinine ratios can be more useful than sUA levels in predicting exacerbation risk (AUC, 0.586 vs. 0.426) and disease severity (AUC, 0.560 vs. 0.475) especially at higher cut-off values, but with low specificity. CONCLUSIONS Our study suggested that sUA levels and sUA/creatinine ratios increased in patients with stable COPD, especially among patients with certain comorbidities compared to healthy controls. At higher cut-off values, sUA levels and especially sUA/creatinine ratios, might be useful in predicting COPD exacerbation risk and disease severity. Also, their association with comorbidities, especially with malignancy and hypertension, may benefit from further investigation.

Protective Effect of Infliximab, a Tumor Necrosis Factor-Alfa Inhibitor, on Bleomycin-Induced Lung Fibrosis in Rats.

We aimed to investigate the preventive effect of Infliximab (IFX), a tumor necrosis factor (TNF)-α inhibitor, on bleomycin (BLC)-induced lung fibrosis in rats. Rats were assigned into four groups as follows: I-BLC group, a single intra-tracheal BLC (2.5 mg/kg) was installed; II-control group, a single intra-tracheal saline was installed; III-IFX + BLC group, a single-dose IFX (7 mg/kg) was administered intraperitoneally (i.p.), 72 h before the intra-tracheal BLC installation; IV-IFX group, IFX (7 mg/kg) was administered alone i.p. on the same day with IFX + BLC group. All animals were sacrificed on the 14th day of BLC installation. Levels of tumor necrosis factor (TNF)-α, transforming growth factor (TGF)-ß, interleukin (IL)-6, periostin, YKL-40, nitric oxide (NO) in rat serum were measured, as well as, myeloperoxidase (MPO), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) activity, and reduced glutathione (GSH), hydroxyproline, malondialdehyde (MDA) content in lung homogenates. Lung tissues were stained with hematoxylin and eosin (H&E) for quantitative histological evaluation. The inducible nitric oxide synthase (iNOS) expression and cell apoptosis in the lung tissues were determined quantitatively by immunohistochemical staining (INOS) and by TUNNEL staining, respectively. BLC installation worsened antioxidant status (such as SOD, CAT, GPx, GSH, MPO), while it increased the serum TNF-α, TGF-ß, IL-6, periostin, YKL-40, and lipid peroxidation, and collagen deposition, measured by MDA and hydroxyproline, respectively. IFX pretreatment improved antioxidant status as well as BLC-induced lung pathological changes, while it decreased the TNF-α, TGF-ß, IL-6, periostin, YKL-40, lipid peroxidation and collagen deposition. Finally, histological, immunohistochemical, and TUNNEL evidence also supported the ability of IFX to prevent BLC-induced lung fibrosis. The results of the present study indicate that IFX pretreatment can attenuate BLC-induced pulmonary fibrosis.

Factors affecting successful treatment outcomes in pulmonary tuberculosis: a single-center experience in Turkey, 2005-2011.

INTRODUCTION: We aimed to describe the treatment outcomes in patients with bacteriologically confirmed pulmonary tuberculosis (PTB) and identify factors associated with successful treatment outcome. METHODOLOGY: The medical charts of patients with smear and/or culture-positive PTB who were treated between 2005 and 2011 at the Kocaeli Tuberculosis Dispensary, Turkey, were reviewed. Patients were categorized as having a successful (cured or with a completed treatment) or poor (treatment default, treatment failure, death) treatment outcome. The association of demographic and clinical factors, including gender, age, education, occupation, insurance, family size, living area, smear and culture positivity, retreatment, comorbidity, drug resistance, and cavity on radiography, with the success of treatment, was evaluated by univariate and multivariate analyses. RESULTS: Of 738 patients (258 females, 480 males) with bacteriologically confirmed PTB, 683 (92.6%) had successful treatment outcomes. Of those with a poor outcome, 29 (3.9%) had treatment default, 18 (2.4%) died, and 8 (1.1%) had treatment failure. Young age, no previous treatment, no comorbidity, no drug resistance, and high education level were factors significantly associated with successful PTB treatment outcome (p < 0.05 for all). CONCLUSIONS: Treatment outcome was successful in young and educated PTB patients who had drug resistance, previous treatment history, and no comorbidities. Knowledge of the factors affecting treatment success will lead to the undertaking of specific measures in the management of PTB, which may help to decrease treatment failure.

Relapse Rate and Factors Related to Relapse in a 1-Year Follow-Up of Subjects Participating in a Smoking Cessation Program.

BACKGROUND: The most important and difficult task when it comes to reducing tobacco-related morbidity and mortality is to convince smokers to quit and to maintain their abstinence. This study aimed to determine the smoking relapse rate and factors related to relapse in subjects who participated in a smoking cessation program and completed a 1-y follow-up in our center. METHODS: The study included 550 subjects who applied to a smoking cessation clinic from June 1, 2011 to December 31, 2011 and completed the 1-y follow-up. RESULTS: After 1 y, 282 (51.4%) subjects had relapsed, 132 (24%) had quit smoking, and 135 (24.6%) could not be contacted. The mean age ± SD was 41.5 ± 10.8 y, and 52.5% were male. There was no difference between non-relapsed and relapsed subjects with regard to age, sex, average smoking duration and daily number of cigarettes, reason to quit, education level, presence of symptoms and concomitant diseases, Fagerström nicotine dependence score, Beck depression score, and frequency of pharmacotherapy administration. In the relapsed group, the age began smoking was younger (P = .05), and the longest prior duration of abstinence was shorter (P = .04). The average number of support contacts was found to be significantly higher in the non-relapsed subjects (P < .001). Logistic regression analysis revealed alcohol intake to be a factor influencing relapse (odds ratio: 2.11, 95% CI: 1.13-3.93, P = .02), as was the number of support contacts (odds ratio: 2.06, 95% CI: 1.59-2.65, P < .001). The presence of drug adverse effects was close to being significant (odds ratio: 1.96, 95% CI: 0.93-4.10, P = .07). CONCLUSION: The relapse rate in a 1-y period was 51.4%. Similar to previous studies, alcohol intake presented a relapse risk. In subjects receiving drug treatment, planning support meetings more frequently and paying attention to adverse effects may increase the success of smoking cessation.

An Unusual Initial Presentation of Sjögren's Syndrome: Severe Hypokalemic Paralysis Secondary to Distal Renal Tubular Acidosis.

Sjögren's syndrome is mainly affects the exocrine glands. Patients usually complain of persistent dryness of the mouth and eyes. However, nonexocrine organs such as the kidneys are often affected in these patients. Distal renal tubular acidosis (dRTA) and interstitiel nephritis are common in Sjögren's syndrome. Nonetheless, severe hypokalemia and paralysis secondary to dRTA are unusual initial manifestation of Sjögren's syndrome. Here, we describe a case of a 48 year old women admitted to the emergency setting with severe hypokalemic paralysis and diagnosed Sjögren's syndrome.
