Introduction
Chronic pancreatitis (CP) is a multifactorial disease. Even though the disease frequency in India and other Asian nations are higher compared to the west, not much published literature with a large cohort exists from this region.
Aims & Methods
Aim: The aim of the study was to develop a database on Chronic Pancreatitis in South-East and South Asia (CPSEASA) to evaluate the demography, environmental risk factors and clinical characteristics of CP in south and southeastern Asia.
Methods: In this ongoing study, 1212 patients were recruited between September 2020 - April 2023 from India (3 sites) and one site each from Bangladesh, Myanmar, Nepal, Malaysia, Sri Lanka and Thailand. We recorded data on demographic details, environmental risk factors, clinical signs and symptoms (including disease duration and pain patterns), family history, morphological finding, patient awareness about the disease, therapeutic interventions and its outcomes in a structured questionnaire. The study approach is mainly based on North American Pancreatitis Study 2 (NAPS2). Continuous data were expressed as mean with standard deviation (SD) and categorical data as proportions.
Results
A total of 1212 patients were included. Mean (SD) age of patients was 37.2 ± 13.91 with males 855 (70.5%). Dravidian 337 (27.5%) was the most prevalent ethnicity, followed by Indo-Aryans 333 (27.5) and North East with 78 (6.4%). Most patients 291 (24.2%) belonged to upper middle. The most common etiology was idiopathic 725 (59.8%), followed by alcohol 365 (30.1%) and smoking 291 (24%). Disease duration of CP (years) was 40 ± 106.05 and acute exacerbations was developed in 406 (33.49%) patients. 1021 (84.24%) of patients had painful CP with a maximum VAS pain score of 7.15 ± 3.02 with the most prominent pain patterns were episodic 387 (31.9%) than continuous 354 (29.2%). Change in character of pain over time was experienced in 192 (15.8%) patients. Other important clinical manifestations included were weight loss 781 (64.4%), back pain 765 (63.3%) and diabetes 497 (41.2%). Dilatation of MPD 928 (76.6%) and parenchymal calcification 699 (57.8%) were the two most frequent morphological abnormalities seen. Normal home-cooked food with frequent fat restriction was commonly consumed in 712 (58.6%) patients. In terms of treatment received, 379 (31.27%) patients reported using analgesics and 254 (20.9%) were prescribed with neuromodulators. Around 557 (45.9%) patients underwent interventions includes endotherapy with ESWL in 454 (37.4%) and surgical procedures in 89 (7.4%) cases. Most patients 912 (75.2%) were adhered to medical treatment. Short-term relief lasting between 3 to 6 months was experienced by 493 (40.7%), while 702 (57.9%) patients experienced pain relapse after initial treatment. Improvement in glycemic control and nutritional status was observed in 557 (46%) and 537 (44.3%) patients respectively.
| Variables | CPSEASA (n=1212) | Europe (n=56) | USA (NAPS 2) (n=521) |
| Mean age (Mean ± SD) | 37.2 ± 13.91 | 44 ± 12.5 | 49 ± 39, 60 |
| Male (n, %) | 855 (70.5) | 46 (82.1) | 283 (53) |
| Etiology | | | |
| Alcohol (n, %) | 365 (30.1) | 38 (68) | 240 (45) |
| Idiopathic (n, %) | 725 (59.8) | 15 (27) | 154 (29) |

| Episodic (n, %) | 387 (31.9) | 31 (55) | 18 (34.6) |
| Continuous (n, %) | 354 (29.2) | 25 (45) | 25 (40.1) |
| Diabetes (n, %) | 497 (41.2) | 16 (29) | 37 (28.4) |
Conclusion
Our data demonstrate that among the few multicenter study from South and Southeast Asia to report several features of CP is different, which distinguishes the epidemiologic trends from those of the West.
