General comment  
This is prospective  observational cohort study which compare a serum values of adipokines and 
other cytokines and CRP in AP patients and healthy subjects. The study is well designed with 
satisfactory number of patients included in study, there are a lot of data included and 
comparisons made. However, a number of data are unnecessary to compare due to lot of studies 
in previous years. This includes prognostic scores and volume of pancreatic necrosis. It is 
enough to compare SOFA and modified CTSI score. Also, on my opinion, if  authors used 
revision of Atlanta classification, they should use and compare only SOFA and modified 
Marshall score between 4 groups of patients. Pancreatic necrosis and volume of necrosis, BISAP 
and HAPS scores  are data which are unnecessary.  
As reporte d previously in several studies, adipokines are important and they have a predictive 
role in course in AP only in obese population. It should be very interesting and possible scientific 
good value if authors perform a division of AP patients according BMI.  After patients 
categorization into maybe 3 groups (normal BMI, obese and very obese) it should be possible to 
made a comparisons between those groups in relation to the disease severity, adipokines and IL -
6 and CRP. After that, the authors could calculate  a cut -off value for adipokines and IL -6 for 
prediction severe form of AP in patients with high BMI. Also, it can be calculate a cut -off value 
for BMI that correlate with high levels of adipokines. This kind of investigation could help in 
routine clinical practice in assessment of high risk (high BMI) patients who have a need for 
adipokines analysis and prediction of severe form of AP. This is worth to discuss!  
The English must be corrected by native English speaker.  
 
 
Specific comment  
Abstract: Background is too long - there is significant benefit in treatment of AP patients - step 
up approach, but there is no benefit for usage of prophylactic antibiotic therapy!!! Early 
classification of AP severity is not remain problematic!!! There is clearly defined cri teria for 
early assessment of AP severity in routine clinical practice! Usage of adiponektins and other 
proinflammatory mediators have only scientific value for now. Maybe in the future.   
There is no need for mentioning revised Atlanta classification seve ral times. The patients were 
categorized according revised Atlanta in 3 groups.  
There is no need for mentioning that CT was performed in patients in abstract. Disease severity 
probably was assessed retrospectively according Atlanta classification based on well defined 
criteria (persistent OF)! This is the main issue for the assessment of AP severity. It must be 
mentioned and reported in abstract and in the methods and results also.  
Methods: If authors used revision Atlanta classification for stratifying patients in 3 groups based 
on the severity, they need to used organ failure as main determinant for disease severity 
assessment! CT is used only for evaluation of morphological change s and indication for 
interventional treatment.  
Results: Well known and supporting facts that affect on decision for intervention, such as 
pancreatic and peripancreatic necrosis in SAP, should not be a issue for comparison neither 
discussion in this paper. The title of this investigation is rule of adipokines in assessment of 
disease severity and outcome.  
The authors should be focused only on this issue, regardless they have a lot of data which are not 
so relevant and are redundant.  
Tables: lot of unnecess ary data.
