Brief Summary:
The purpose of this study was to determine the effects (good and bad) of giving a drug called pentoxifylline to patients with acute pancreatitis.

Condition or disease Intervention/treatment Phase
Acute Pancreatitis (AP) Gallstone Pancreatitis Alcoholic Pancreatitis Trauma Acute Pancreatitis Hypertriglyceridemia Acute Pancreatitis Idiopathic (Unknown) Acute Pancreatitis Medication Induced Acute Pancreatitis Cancer Acute Pancreatitis Miscellaneous (i.e. Acute on Chronic Pancreatitis) Drug: Pentoxifylline Drug: Placebo Phase 3

Detailed Description:

Participants were randomized to either the treatment group (Pentoxifylline medication) or the control group (Placebo).

Participant took a pill orally, starting from the time of admission. Participants received a total of 9 doses over the three days of hospitalization (72 hours).

Research blood draws were done at baseline and on 5 successive days or until the time of discharge, whichever occured earlier. The study gathered clinical follow up information up to 4 months following hospitalization regarding the diagnosis of acute pancreatitis.

Arm Intervention/treatment
Experimental: Pentoxifylline
Pentoxifylline, 400 mg, 3 times daily by mouth from time of enrollment until 72 hours from enrollment. Subjects to receive up to a maximum of 9 doses.
Drug: Pentoxifylline
Pentoxifylline is a competitive nonselective phosphodiesterase inhibitor which raises intracellular cyclic adenosine monophosphate (cAMP), activates protein kinase A (PKA), inhibits Tumor Necrosis Factor (TNF) and leukotriene synthesis, and reduces inflammation and innate immunity. In addition, pentoxifylline improves red blood cell deformability (known as a haemorrheologic effect), reduces blood viscosity and decreases the potential for platelet aggregation and thrombus formation.Pentoxifylline is also an antagonist at adenosine 2 receptors
Other Names:
  • Trental
  • Pentox
  • Pentoxil
  • Flexital

Placebo Comparator: Placebo
Placebo 3 times daily by mouth from time of enrollment until 72 hours from enrollment. Subjects to receive up to a maximum of 9 doses.
Drug: Placebo
A harmless pill that has no therapeutic effect, used as a control in testing of investigational drug

Primary Outcome Measures :
  1. Change in C-reactive Protein (C-RP) From Admission Baseline at One Week. [ Time Frame: Admission (baseline), day 5 ]
    C-reactive protein is a substance produced by the liver in response to inflammation. Normal C-RP levels are below 3.0 mg/L.Units: mg/L

  2. Change in Tumor Necrosis Factor-alpha (TNF-a) Levels From Admission Baseline at One Week. [ Time Frame: Admission (baseline), day 5 ]
    Tumor Necrosis Factor Alpha is a cell signaling protein (cytokine) involved in systemic inflammation and is one of the cytokines that make up the acute phase reaction. TNF is important to the body because it helps regulate the response of the immune system to a foreign object, especially to the present cancerous tumor. It promotes inflammation, produces other cells used in the inflammatory response, and can help cells heal. The normal range is 5 to 27.2 pg/ml.Units: pg/ml

  3. Change in Interleukin-6 (IL-6) Levels From Admission Baseline at One Week. [ Time Frame: Admission (baseline), day 5 ]
    Interleukin-6 (IL-6) may be used to help evaluate a person who has a condition associated with inflammation, such as lupus or rheumatoid arthritis, or with infection, such as sepsis. It may also be used in the evaluation of diabetes or cardiovascular disease. IL-6 is a cytokine, a protein produced by immune cells that acts on other cells to help regulate and/or promote an immune response. It also stimulates the production of acute phase reactants, proteins that increase in the blood with conditions that cause inflammation or tissue injury. Circulating IL-6 can be found in the blood of normal individuals in the 1 pg/mL range, with slight elevations during the menstrual cycle, modest elevations in certain cancers (melanoma) (10 pg/mL), and large elevations after surgery (30-430 pg/mL).Units: pg/ml

  4. Change in Interleukin-8 (IL-8) Levels From Admission Baseline at One Week. [ Time Frame: Admission (baseline), day 5 ]
    IL-8 is a chemotactic factor that attracts neutrophils, basophils, and T-cells, but not monocytes. It is also involved in neutrophil activation. It is released from several cell types in response to an inflammatory stimulus. Units: pg/mL
