Introduction Contrast-induced acute kidney injury (CI-AKI) is a serious complication of angiographic procedures with significant morbidity and mortality. We aimed to find the incidence, risk factors and outcomes of CI-AKI in patients who have undergone coronary angiography/angioplasty in a referral hospital in Nepal. MethodsIt was a descriptive observational study of consenting consecutive patients above 18 years undergoing coronary angiography/angioplasty at Manmohan Cardiothoracic Vascular and Transplant Centre, Nepal from July 2015 to September 2017. CI AKI was defined as an elevation of serum creatinine of >25% or ≥0.5 mg/dl (44 μmol/L) from baseline within 48 hour of exposure to contrast. Statistical analysis was performed using SPSS 18 software. Statistical analysis was completed using Student’s t-test, chi-square test and multivariable logistic regression analysis. ResultsOut of 240 patients, 156 (65%) were male, mean age was 60.36±11.29 years. Eighteen patients (7.5%) developed CI-AKI. Incidence of CI-AKI was 20% in patients with chronic kidney disease (CKD), 5.4% in diabetics, 13.6% in patients >70 years, 12.79 % in patients with anaemia and 12.3% in patients with prior contrast exposure. Multivariate logistic regression analysis found smoking and history of prior contrast exposure to be independent predictors for development of CI-AKI. Among patients with CI-AKI, one (5.88%) required dialysis and one (5.88%) died. ConclusionIncidence of CI-AKI after coronary angiography/angioplasty was 7.5%. Patients with prior contrast exposure and smoking were at significantly increased risk of CI-AKI; higher trend of CI-AKI was seen in patients with CKD, diabetes, elderly and anaemia.

Community-acquired pneumonia (CAP) remains a common and serious illness, in spite of the availability of potent new antimicrobials and effective vaccines. Despite Nepal being one of the four developing countries accounting for 40.0% of global acute respiratory infections, studies on CAP are limited and the status of adult pneumonia in our community is unknown. This cross-sectional study reviewed the clinical, bacteriological, radiological profile of 100 cases of adult CAP and followed them during the hospital stay for the outcome. The age group with the highest incidence was 60-79 years with females (55.0%) being more affected than males (45.0%). Risk factors were present in 86.0% of cases, chronic obstructive pulmonary disease (COPD), and smoking was the most common, each present in 43.0% of cases. The most common presenting feature was cough (89.80%) followed by sputum production (78.60%), fever (67.30%), shortness of breath (63.30%), chest pain (38.80%), gastrointestinal symptoms (26.50%), altered sensorium (13.30%), and hemoptysis (13.30%). Only 48.0% of patients had leukocytosis. Klebsiella pneumoniae was the most frequent organism isolated (n=4) followed by Pseudomonas aeruginosa (n=3). Fungi were isolated in 3 cases. Lobar pneumonia was seen in 99.0% of cases with the right lower zone being the most commonly involved zone on chest x-ray. Severe pneumonia with CURB-65 (confusion, blood urea nitrogen, respiratory rate, blood pressure, age>65) Score ≥3 was seen in 15.0% of cases. The mean hospital stay was 7.55 days with 28 cases requiring ICU admission and 5 cases of mortality.
