This study is conducted to observe the association of diabetes (DM), hypertension (HTN) and chronic kidney disease (CKD) on the prognosis and mortality of COVID-19 infection in hospital admitted patients with above mentioned comorbidities. This is a single centre, observational, retrospective study carried out at Sir Ganga Ram Hospital, Delhi, India. The burden of comorbidities on the prognosis and clinical outcome of COVID-19 patients admitted patients from April 8, 2020, to October 4, 2020. Chi-square and relative risk test were used to observe the association of comorbidities and disease prognosis. A total of 2586 patients were included in the study consisting of 69.6% of male patients. All the comorbidities were significantly associated with ICU admission and mortality. The relative risk showed that CKD is most prone to severity as well as mortality of the COVID-19 infection followed by HTN and DM. Further with the increase in number of underlying comorbidities, the risk of ICU admission and mortality also increases. Relative risk of the severity of COVID-19 infection in younger patients with underlying comorbidities are relatively at higher risk of severity of disease as well as to mortality compared to the elderly patients with similar underlying condition. Similarly, it is found that females are relatively at higher risk of mortality as compared to the males having same comorbid conditions except for the hypertensive patients. Diabetes, hypertension and CKD, all are associated with progression of COVID-19 disease to severity and higher mortality risk. The number of underlying comorbid condition is directly proportional to the progression of disease severity and mortality., (© 2022.

Purpose: Considering various factors, such as multiple co-morbidities, unsuitable vessels for access creation, non-maturation, vascular calcifications, the outcome of arteriovenous fistula (AVF) in the elderly population, may not be similar to the younger people. Our study aims to analyze the outcomes of AVF in elderly patients (> 65 year)., Methods: It was a prospective observational study. Patients of more than 65 years of age in whom AVF was created from January 2012 to December 2015 were included in the study. These patients were followed up for 4 years. The primary endpoint of our study was to assess primary and secondary patency rates., Results: A total of 450 AVFs were included in the study. The mean age was 68.5 years. The most common site of AVF was radiocephalic (RCAVF) in 70% (n = 315), brachiocephalic (BCAVF) in 24% (n = 108) and basilic vein transposition (BVT) in 6% (n = 27). At 48 months, the primary patency rate of RCAVF, BCAVF, and BVT was 55%, 61.6%, and 60.4%, respectively. The commonest cause of access failure was thrombosis followed by non-maturation., Conclusion: AVF remains the preferred vascular access for hemodialysis even in the elderly population. Failure to mature and thrombosis continue to be a concern with AVF. Location of the AV access does not seem to impact the long-term patency., (© 2021.

Aim: We aimed to study the clinical profile, prognostic factors, and the 6-month outcome of patients with emphysematous pyelonephritis (EPN) METHODS: All patients admitted with a diagnosis of emphysematous pyelonephritis between January 2001 and July 2007 were included., Results: Overall 19 cases were diagnosed to have emphysematous pyelonephritis. There were 16 females and three males. Fourteen cases had type 2 diabetes mellitus. Fourteen cases had unilateral involvement and five had bilateral involvement. Eleven cases were classified as having class 1 or 2 disease and eight cases had class 3 and 4 disease. E. coli was the most common organism cultured (68.4%). Five cases underwent percutaneous drainage of the collecting system and three cases had nephrectomy of which 10.5% (two with advanced disease) expired. Shock at admission (p = 0.03), serum creatinine >5.0 mg/dl (p = 0.035) and DIC (p = 0.017) were independent poor prognostic factors. There was no difference in the prognosis between patients who had >or=2 or <2 poor prognostic factors (p = 0.16). However, prognosis was not related to disease class, unilateral vs. bilateral involvement, sepsis or the age of the patient. At 6 months, two patients were on maintenance hemodialysis., Conclusions: In cases of EPN, shock, serum creatinine >5.0 mg/dl and DIC at admission are poor prognostic factors. Larger prospective studies are needed to confirm our findings.
