ABSTRACT
INTRODUCTION: Limited evidence exists on the optimal strategy to correct iron deficiency anemia after variceal bleeding (VB) in cirrhosis. This trial compared the efficacy and safety of intravenous ferric carboxymaltose (IV-FCM) with those of oral iron therapy in this cohort. METHODS: In this open-label, single-center, randomized controlled trial, eligible patients with hemoglobin <10 g/dL and iron deficiency (ferritin <100 ng/mL) after VB received either IV-FCM (1,500-2,000 mg) divided into 2 doses (n = 48) or oral carbonyl iron (100 mg elemental iron/day) (n = 44) for 3 months. The primary outcome was change in hemoglobin at 3 months. Secondary outcomes included improvement in anemia (last hemoglobin >12 g/dL), normalization of iron stores (ferritin >100 ng/mL), liver-related adverse events, adverse drug reactions, and changes in quality of life (CLDQOL questionnaire). RESULTS: Baseline characteristics, including median Child-Turcotte-Pugh score 7 (interquartile range [IQR] 6-9), Model for End-Stage Liver Disease score 12 (IQR 10-17), blood hemoglobin (8.25 ± 1.06 g/dL), and ferritin (30.00 ng/mL [15.00-66.50]), were comparable in both arms. The median increase in hemoglobin at 3 months in the IV and oral arms was 3.65 g/dL (IQR 2.55-5.25) and 1.10 g/dL (IQR 0.05-2.90 g/dL) ( P < 0.001), respectively. Iron stores normalized in 84.6% and 21% of the IV and oral arms, respectively ( P < 0.001). Anemia improved in 50% and 21.9% in the IV and oral arms, respectively ( P < 0.009). Patients in the IV arm showed a significant improvement in all domains of CLDQOL. Liver-related adverse events were comparable in both arms. Transient mild/moderate hypophosphatemia developed in 43% of patients receiving IV-FCM. DISCUSSION: Intravenous iron replacement is efficacious and safe to treat iron deficiency anemia after VB in patients with cirrhosis.
ABSTRACT
BACKGROUND AND AIMS: Lumbar vertebral bone attenuation, measured in Hounsfield units (HU) can indirectly indicate the bone mineral density (BMD). The aim of this study is to determine the optimal HU threshold on abdominal computed tomography (CT) scans to detect osteopathy in patients with chronic pancreatitis (CP). METHODS: This cross-sectional study included patients with CP who underwent CT scans to measure HU at L1 to L4 vertebrae. The mean lumbar vertebral attenuation of female renal transplant donors, aged 20-30 years was utilized to calculate the T-scoreHU of all patients at each vertebral level. Receiver operator characteristic analysis was used to determine the HU and T-scoreHU for diagnosis of osteopathy in patients with CP. Dual-energy X-ray absorptiometry value was used to categorize osteopenia and osteoporosis. RESULTS: A total of 175 patients (mean age, 34.5 ± 10.9 years; 72 % males) and 33 female renal transplant donors (mean age, 28 ± 2.4 years) were included. A threshold HU value 212 or T scoreHU of -1.80 at L1 vertebra was found to have a 78 % sensitivity and 70 % specificity for differentiating between osteoporosis and non-osteoporosis (osteopenia and normal BMD). Similarly, a threshold HU value of 254 or a T-scoreHU of -0.46 at L1 vertebra had 78 % sensitivity and 71 % specificity for distinguishing between normal and low BMD (osteoporosis and osteopenia). CONCLUSION: Abdominal CT images, which are routinely performed in chronic pancreatitis, can be used for opportunistic screening of osteoporosis and osteopenia without additional cost or radiation exposure.

PURPOSE: To compare the efficacy and safety of a thromboelastography (TEG)-guided platelet transfusion strategy to empirical or on-demand transfusions in patients with cirrhosis and severe thrombocytopenia (platelet counts <50 x109/L) undergoing high-risk invasive procedures. MATERIALS AND METHODS: This was a single-center, single-blinded, randomized controlled trial. Patients with cirrhosis and severe thrombocytopenia undergoing high-risk invasive procedures were randomized into three groups- TEG group: transfusions based on TEG parameters; SOC group: 3 units of random donor platelets pre-procedure; On-demand group: transfusions based on procedural adverse effects /clinician's discretion. The primary outcome was periprocedural platelet transfusion in each arm. RESULTS: Eighty-seven patients were randomized (29 in each group) with no significant differences in demographics/coagulation profile/procedures. The median platelet count was 33 x109/L (IQR: 26-43). Percutaneous liver biopsy was the most common procedure (46, 52.9%). Significantly lower number of patients in the TEG group received platelets (4 cases, 13.8%; 95%CI: 3.9-31.7) compared to SOC (100%; 95%CI: 88.1-100) (p<0.001). Four patients in the on-demand group received platelets (13.8%; 95%CI: 3.9-31.7). Minor (WHO grade 2) procedure-related bleeding occurred in 3 (10%; 95%CI: 2.2-27.4) patients in the TEG-guided transfusion group, compared to 1 (3.4%; 95%CI: 0.1-17.8) each in SOC and on-demand groups, respectively (p=0.43) although our sample size was underpowered for comparison of outcomes such as post-procedural bleeding. No bleeding-related mortality was observed in any of the three groups. CONCLUSION: Thromboelastography-guided transfusion reduces prophylactic transfusions in patients with cirrhosis and severe thrombocytopenia undergoing high-risk invasive procedures.

ABSTRACT
INTRODUCTION: Limited data exist on long-term outcomes of patients with compensated cirrhosis presenting with acute variceal bleeding (AVB) as an index and lone decompensating event. This study aimed to evaluate the incidence of further decompensation, survival, and risk factors of mortality in these patients. METHODS: Patients with otherwise compensated cirrhosis presenting with AVB as their index decompensating event (n = 463) were analyzed in this single-center retrospective study. The incidence of individual decompensation events and survival was estimated using competing risk analysis. Risk factors for poor outcomes were identified. RESULTS: The mean age was 47.4 (13.2) years, with most patients (86.5%) being males. Alcohol-related liver disease (42.3%) and viral cirrhosis (22.4%) were the main etiologies with a median Model for End-Stage Liver Disease score of 14 (11-15) at baseline. Over a median follow-up of 42 (24-62) months, 292 patients experienced further decompensations: ascites (n = 283; 96.9%), rebleeding (n = 157; 53.8%), and hepatic encephalopathy (n = 71; 24.3%). Most events occurred with similar frequency across different etiologies, except acute-on-chronic liver failure, which was more common in nonviral cirrhosis (Gray test, P = 0.042). Patients with viral and nonviral cirrhosis had similar survival (5-year survival: 91% and 80.1%, respectively; P = 0.062). Patients with early further decompensations (onset <6 weeks of index AVB event) (n = 40) had a higher mortality (52.5% vs 20.2% for late decompensations; P < 0.001). Active alcohol consumption (hazard ratio [HR]: 9 [5.31-15.3], P < 0.001), high white blood cell count at presentation (HR: 2.5 [1.4-4.4], P = 0.001), and early decompensation (HR: 6.2 [3.6-10.6], P < 0.001) predicted poor survival. DISCUSSION: Despite a high incidence of further decompensation, 5-year survival of patients at this stage of cirrhosis is more than 80% across all etiologies in the absence of early further decompensation and active alcohol consumption.

INTRODUCTION: Chronic isolated terminal ileitis (TI) may be seen in Crohn's disease (CD) and intestinal tuberculosis (ITB) in addition to other etiologies that may be managed symptomatically. We developed a revised algorithm to distinguish patients with a specific etiology from a nonspecific etiology. METHODS: Patients with chronic isolated TI followed up from 2007 to 2022 were retrospectively reviewed. A specific (ITB or CD) diagnosis was made based on standardized criteria, and other relevant data were collected. Using this cohort, validation of a previously suggested algorithm was conducted. Furthermore, based on the results of a univariate analysis, a multivariate analysis with bootstrap validation was used to develop a revised algorithm. RESULTS: We included 153 patients (mean age 36.9 ± 14.6 years, males-70%, median duration-1.5 years, range: 0-20 years) with chronic isolated TI of whom 109 (71.2%) received a specific diagnosis (CD-69, ITB-40). On multivariate regression and validation statistics with a combination of clinical, laboratory, radiological, and colonoscopic findings, an optimism corrected c-statistic of 0.975 and 0.958 was obtained with and without histopathological findings, respectively. Revised algorithm, based on these, showed sensitivity, specificity, positive and negative predictive values, and overall accuracy of 98.2% (95% CI: 93.5-99.8), 75.0% (95% CI: 59.7-86.8), 90.7% (95% CI: 85.4-94.2), 94.3% (95% CI: 80.5-98.5) and 91.5%(95% CI:85.9-95.4), respectively. This was more sensitive and specific than the previous algorithm (accuracy 83.9%, sensitivity 95.5%, and specificity 54.6%). DISCUSSION: We developed a revised algorithm and a multimodality approach to stratify patients with chronic isolated TI into specific and nonspecific etiologies with an excellent diagnostic accuracy, which could potentially avoid missed diagnosis and unnecessary side effects of treatment.

INTRODUCTION: Quantitative fecal fat estimation is the gold standard test to diagnose steatorrhea (fecal fat >7 g/day) in chronic pancreatitis (CP), but cumbersome and inconvenient. So, fecal elastase-1 (FE) is proposed as a good alternative but the data on the diagnostic utility of FE to diagnose steatorrhea is variable. METHODS: This retrospective study included adult CP patients evaluated with both 24-h fecal-fat and FE tests within a 3-month period. The objective was to evaluate the diagnostic performance of FE to diagnose steatorrhea and to evaluate the FE progression over 9-month period. RESULTS: Among the 147 included patients, the frequency of steatorrhea (fecal fat >7 g/day) was 34%. The sensitivity, specificity, and negative likelihood ratio (LR) of FE was 90%, 28.9% and 0.35 at cut-off of <100 µg/g stool to diagnose steatorrhea; and 96%, 11.3% and 0.35 at cut-off of <200 µg/g stool, respectively. The optimal cut-off of FE was <20 on receiver operating characteristic curve (sensitivity 66%; specificity 69%; positive LR 2.14). There was no statistically significant variation in FE levels over 9 months interval among a hundred patients. CONCLUSION: Compared to FE ≥ 200 µg/g stool, FE ≥ 100 can used to exclude steatorrhea (better specificity and negative LR). FE < 20 alone cannot replace fecal fat estimation to confirm steatorrhea but to be interpreted with clinical features. Repeat FE testing for exocrine insufficiency progression can be done at least a year later.

BACKGROUND AND AIMS: The role of intestinal-barrier in acute pancreatitis(AP) is poorly understood. We aimed to assess structural and functional changes in the intestinal-barrier in patients with early AP (time from onset<2 weeks) and the effect of enteral nutrition on them. METHODS: In this prospective observational study, patients with early AP not on enteral nutrition were compared with controls for baseline intestinal-permeability(lactulose: mannitol ratio(L:M)), endotoxinemia(serum IgM/IgG anti-endotoxin antibodies), bacterial-translocation(serum bacterial 16S rRNA) and duodenal epithelial tight-junction structure by immunohistochemistry(IHC) for tight-junction proteins(claudin-2,-3,-4, zonula occludens-1(ZO1), junctional adhesion molecule(JAM) and occludin) and electron microscopy. These parameters were reassessed after 2 weeks enteral feeding in a AP patients subset. RESULTS: 96 patients with AP(age: 38.0 ± 14.5 years; etiology: biliary[46.8%]/alcohol[39.6%]; severe:53.2%, mortality:11.4%) and 40 matched controls were recruited. Patients with AP had higher baseline intestinal permeability(median L:M 0.176(IQR 0.073-0.376) vs 0.049(0.024-0.075) in controls; p < 0.001) and more frequent bacteraemia(positive bacterial 16S rRNA in 24/48 AP vs 0/21 controls; p < 0.001) with trend towards higher serum endotoxinemia(median IgG anti-endotoxin 78(51.2-171.6) GMU/ml vs 51.2(26.16-79.2) in controls; p = 0.061). Claudin-2, claudin-3, ZO1 were downregulated in both duodenal crypts and villi while claudin-4 and JAM were downregulated in duodenal villi and crypts respectively. 22 AP patients reassessed after initiation of enteral nutrition showed trend towards improving intestinal permeability, serum endotoxinemia and bacteraemia, with significant improvement in claudin-2,-3 in duodenal villi. CONCLUSION: Patients with AP have significant disturbances in intestinal barrier structure and function in first 2 weeks from onset that persist despite institution of enteral nutrition.

BACKGROUND: The effects of chronic pancreatitis (CP) on pregnancy and vice versa have not been studied well. We aimed to study the impact of CP on pregnancy-related outcomes and the effect of pregnancy on clinical profile of CP. STUDY AND GOALS: We did a retrospective analysis of all female patients of CP of child-bearing age (above 18 y). The pregnancy-related outcomes of patients with CP were compared with the age-matched 115 controls from the low-risk pregnancy group identified using a simplified antepartum high-risk pregnancy scoring form. The clinical course of CP during pregnancy was compared with the pre-pregnancy course. RESULTS: Among the 338 eligible patients, 46 patients were included after exclusions. All these 46 patients had at least 1 conception and 41 had at least 1 completed pregnancy with a total of 117 conceptions and 96 completed pregnancies. The pregnancy-related outcomes in patients with CP like abortions (21.7% vs. 11.3%; P =0.087), preterm deliveries (14.6% vs. 10.4%; P =0.47), antepartum course (82.7% vs. 82.6%; P =0.58), stillbirths (4.9% vs. 4.3%; P =0.88), cesarean section (36.6% vs. 34%; P =0.849) were comparable with controls. There was overall improvement in the severity and frequency of pain during pregnancy as compared with the pre-pregnancy symptoms ( P =0.001). CONCLUSION: CP is not associated with adverse pregnancy outcomes. Also, there is trend toward improvement in the clinical symptoms because of CP during the pregnancy.

BACKGROUND AND AIMS: Assessment of clinically significant portal hypertension (CSPH) non-invasively using a combination of liver stiffness measurement (LSM) and platelet counts is proposed as an alternative to hepatic venous pressure gradient (HVPG) estimation. Utility of these criteria in compensated advanced chronic liver disease (cACLD) patients of different etiologies including nonalcoholic steatohepatitis (NASH) with BMI > 30 kg/m2 was studied in a large cohort. METHODS: Consecutive patients of cACLD with available anthropometric and laboratory details, LSM, and HVPG were included in a retrospective analysis. A LSM of ≥ 25 kPa alone and LSM ≤ 15 kPa plus platelets ≥ 150 × 109/L were evaluated as non-invasive rule-in and rule-out criteria for CSPH, respectively. The NASH-ANTICPATE model (composite of BMI, platelets, and LSM) was evaluated in patients with obese NASH. RESULTS: Patients with cACLD (n = 626) (mean age: 50.8 ± 12.4 years, 74.2% males) with alcohol (ALD, 30.3%), NASH (26.4%), hepatitis C (HCV, 16.6%), hepatitis B (HBV,10.2%) etiology were included. The prevalence of CSPH was > 80% across all etiologies except in HBV (62.5%) and in obese non-NASH (71-72%). The rule-in criteria had a PPV > 90% for all etiologies except in HBV (80.8%). The rule-out criteria had a negative predictive value (NPV) of 65%, 53%, and 40% in ALD, HCV, and NASH, respectively. The NASH-ANTCIPATE model had specificity of 100% and NPV of 33% to detect CSPH in obese NASH (n = 62). CONCLUSIONS: LSM ≥ 25 kPa predicted CSPH in most etiologies except HBV. A significant proportion of patients have CSPH despite satisfying the rule-out criteria. The NASH-ANTICIPATE model is specific but fails to exclude CSPH in nearly two-third patients with obesity and NASH. There is a need for precise disease-specific non-invasive models for detecting CSPH.

INTRODUCTION: Malnutrition in chronic pancreatitis (CP) has prognostic value and there is limited data on the prevalence, predictors of malnutrition in CP and its effect on Quality of life (QoL). METHODS: A retrospective study was conducted in patients with CP to assess the prevalence of malnutrition as per the Global Leadership Initiative on Malnutrition (GLIM) criteria. Multivariable-adjusted regression was used to identify independent predictors of both malnutrition and global QoL. RESULTS: A total of 297 patients were included and the most common etiology of CP was idiopathic (75%) and alcohol (25%). The prevalence of malnutrition was 46.4% as per GLIM criteria. On univariate analysis, the risk of malnutrition was significantly higher in alcoholic etiology (p = 0.001), current alcohol consumption (p = 0.001), smokers (p < 0.001), those having higher cumulative days of pain in last 6 months (p < 0.001) and lower daily calorie intake (p = 0.019). On multivariate analysis, malnutrition was independently associated with current alcohol consumption (Odds ratio: 3.22, p = 0.017), current smokers (OR: 2.23, p = 0.042) and those having higher cumulative days of abdominal pain (OR: 1.01, p < 0.001), while higher daily calorie intake (per 100 kcal) (OR:0.94, p = 0.023) has reduced risk of malnutrition. Malnutrition (p = 0.015) and higher cumulative days of abdominal pain (p < 0.001) were independently associated with lower global QoL in patients with CP. CONCLUSION: Malnutrition is frequent in patients with CP; and current alcohol consumption, smoking and higher cumulative days of abdominal pain independently predicts risk of developing malnutrition. Patients with malnutrition and higher cumulative days of pain has poorer quality of life.

BACKGROUND AND AIM: Risk stratification beyond the endoscopic classification of esophageal varices (EVs) to predict first episode of variceal bleeding (VB) is currently limited in patients with compensated advanced chronic liver disease (cACLD). We aimed to assess if machine learning (ML) could be used for predicting future VB more accurately. METHODS: In this retrospective analysis, data from patients of cACLD with EVs, laboratory parameters and liver stiffness measurement (LSM) were used to generate an extreme-gradient boosting (XGBoost) algorithm to predict the risk of VB. The performance characteristics of ML and endoscopic classification were compared in internal and external validation cohorts. Bleeding rates were estimated in subgroups identified upon risk stratification with combination of model and endoscopic classification. RESULTS: Eight hundred twenty-eight patients of cACLD with EVs, predominantly related to non-alcoholic fatty liver disease (28.6%), alcohol (23.7%) and hepatitis B (23.1%) were included, with 455 (55%) having the high-risk varices. Over a median follow-up of 24 (12-43) months, 163 patients developed VB. The accuracy of machine learning (ML) based model to predict future VB was 98.7 (97.4-99.5)%, 93.7 (88.8-97.2)%, and 85.7 (82.1-90.5)% in derivation (n = 497), internal validation (n = 149), and external validation (n = 182) cohorts, respectively, which was better than endoscopic classification [58.9 (55.5-62.3)%] alone. Patients stratified high risk on both endoscopy and model had 1-year and 3-year bleeding rates of 31-43% and 64-85%, respectively, whereas those stratified as low risk on both had 1-year and 3-year bleeding rates of 0-1.6% and 0-3.4%, respectively. Endoscopic classification and LSM were the major determinants of model's performance. CONCLUSION: Application of ML model improved the performance of endoscopic stratification to predict VB in patients with cACLD with EVs.

INTRODUCTION: Both transient elastography (TE)-based and non-TE-based criteria exist for detection of varices needing treatment (VNT) in patients with asymptomatic advanced chronic liver disease (CLD). However, their performance in clinical settings at different risk thresholds of detection of VNT and in regions where elastography is not widely available is unknown. We aimed to validate existing noninvasive criteria in our patients with CLD and identify best TE- and non-TE-based criteria for VNT screening at usual risk thresholds. METHODS: Patients with compensated advanced CLD (cACLD) who underwent esophagogastroduodenoscopy and TE within 3 months were included. Diagnostic performance of Baveno VI, expanded Baveno VI, platelet-model for end-stage liver disease, and platelet-albumin (Rete Sicilia Selezione Terapia-hepatitis C virus) criteria were estimated. Decision curve analysis was conducted for different predictors across range of threshold probabilities. A repeat analysis including all patients with compensated CLD (cACLD and non-cACLD) was performed to simulate absence of TE. RESULTS: A total of 1,657 patients (cACLD, 895; non-cACLD, 762) related to hepatitis B virus (38.2%), hepatitis C virus (33.4%), nonalcoholic steatohepatitis (14.7%), and alcohol (11.8%) were included. Baveno VI identified maximum VNT (97.3%) and had best negative predictive value (96.9%), followed by platelet-albumin criteria. Expanded Baveno VI and platelet-model for end-stage liver disease had intermediate performance. At threshold probability of 5%, Baveno VI criteria showed maximum net benefit, and platelet-albumin criteria was next best, with need for 95 additional elastographies to detect 1 additional VNT. Similar results were obtained on including all patients with compensated CLD irrespective of TE. DISCUSSION: Baveno VI criteria maximizes VNT yield at 5% threshold probability. An acceptable alternative is the platelet-albumin criteria in resource-limited settings.

INTRODUCTION: Vascular complications such as venous thrombosis (VT) and pseudoaneurysm are not uncommon in patients with chronic pancreatitis (CP). The aim of this study to was to evaluate the prevalence and risk factors for vascular complications in patients with CP. METHODS: A retrospective analysis of a prospectively maintained database of patients with CP presenting from January 2002 to August 2019 was performed. Venous thrombosis and pseudoaneurysm were identified using radiological imaging, and their risk factors were identified using multivariate Cox-proportional hazards. RESULTS: Of 1363 patients with CP, 166 (12.2%) had vascular complications. Isolated VT was present in 132, pseudoaneurysm in 17, and both in 17 patients. They were more commonly seen in males and alcoholic CP (ACP), and less commonly in patients with pancreatic atrophy and calcification. It involved the vessels in the closest proximity to the pancreas, VT most commonly involving the splenic vein whereas pseudoaneurysm most commonly involved the splenic artery. Alcoholic CP [odds ratio (OR) 2.1, p = 0.002], pseudocyst (OR 4.6, p < 0.001) and inflammatory head mass (OR 3.1, p = 0.006) were independent risk factors for VT, whereas ACP (OR 3.49, p = 0.006) and pseudocyst (OR 3.2, p = 0.002) were independent risk factors for pseudoaneurysm. Gastrointestinal bleed occurred in 3.5% patients, and more commonly in patients with pseudoaneurysm than VT (64.7% vs 15.9%), and in patients with ACP in comparison to other etiologies (p < 0.001). CONCLUSION: Vascular complications are a common complication of CP, VT being more frequent than pseudoaneurysm. Pseudocyst and ACP are independent risk factors for the development of vascular complications.

BACKGROUND: The natural course of chronic pancreatitis(CP) and its complications has been inadequately explored. We aimed to describe the natural history and factors affecting the progression of alcoholic(ACP), idiopathic juvenile(IJCP) and idiopathic senile(ISCP) variants of CP. METHODS: This study was a retrospective analysis from a prospectively maintained database of patients with CP following up at a tertiary care centre from 1998 to 2019. Cumulative rates of pain resolution, diabetes, steatorrhea, pseudocysts and pancreatic cancer were computed using Kaplan-Meier analysis, and the factors affecting their incidence were identified on multivariable-adjusted Cox-proportional-hazards model. RESULTS: A total of 1415 patients were included, with 540(38.1%) ACP, 668(47.2%) IJCP and 207(14.6%) ISCP with a median follow-up of 3.5 years(Inter-quartile range: 1.5-7.5 years). Diabetes occurred at 11.5, 28 and 5.8 years(p < 0.001) while steatorrhea occurred at 16, 24 and 18 years(p = 0.004) after onset for ACP, IJCP and ISCP respectively. Local complications including pseudocysts occurred predominantly in ACP(p < 0.001). Ten-year risk of pancreatic cancer was 0.9%, 0.2% and 5.2% in ACP, IJCP and ISCP, respectively(p < 0.001). Pain resolution occurred more frequently in patients with older age of onset[Multivariate Hazard Ratio(HR):1.7(95%CI:1.4-2.0; p < 0.001)], non-smokers[HR:0.51(95%CI:0.34-0.78); p = 0.002] and in non-calcific CP[HR:0.81(0.66-1.0); p = 0.047]. Occurrence of steatorrhea[HR:1.3(1.03-1.7); p = 0.028] and diabetes[HR:2.7(2.2-3.4); p < 0.001] depended primarily on age at onset. Occurrence of pancreatic cancer depended on age at onset[HR:12.1(4.7-31.2); p < 0.001], smoking-history[HR:6.5(2.2-19.0); p < 0.001] and non-alcoholic etiology[HR:0.14(0.05-0.4); p < 0.001]. CONCLUSION: ACP, IJCP and ISCP represent distinct entities with different natural course. Age at onset of CP plays a major prognostic role in all manifestations, with alcohol predominantly causing local inflammatory complications.

OBJECTIVE: The authors aimed to evaluate the antimicrobial susceptibility pattern of Acinetobacter isolates responsible for nosocomial meningitis/ventriculitis in the neurosurgical ICU. The authors also sought to identify the risk factors for mortality following Acinetobacter meningitis/ventriculitis. METHODS: This was a retrospective study of 72 patients admitted to the neurosurgical ICU between January 2014 and December 2018 with clinical and microbiological diagnosis of nosocomial postneurosurgical Acinetobacter baumanii meningitis/ventriculitis. Electronic medical data on clinical characteristics, underlying pathology, CSF cytology, antibiotic susceptibilities, and mortality were recorded. To evaluate the outcome following nosocomial postneurosurgical Acinetobacter meningitis/ventriculitis, patients were followed up until discharge or death in the hospital. Kaplan-Meier survival analysis and multivariable Cox proportional hazards models were used to compute factors affecting survival. RESULTS: The study population was divided into two groups depending on the final outcome of whether the patient died or survived. Forty-three patients (59.7%) were included in the survivor group and 29 patients (40.3%) were included in the nonsurvivor group. Total in-hospital mortality due to Acinetobacter meningitis/ventriculitis was 40.3% (29 cases), with a 14-day mortality of 15.3% and a 30-day mortality of 25%. The 43 (59.7%) patients who survived had a mean length of hospital stay of 44 ± 4 days with a median Glasgow Outcome Scale-Extended score at discharge of 6. On univariate analysis, age > 40 years (p = 0.078), admission Glasgow Coma Scale (GCS) score ≤ 8 (p = 0.003), presence of septic shock (p = 0.011), presence of external ventricular drain (EVD) (p = 0.03), CSF white blood cell (WBC) count > 200 cells/mm3 (p = 0.084), and comorbidities (diabetes, p = 0.036; hypertension, p = 0.01) were associated with poor outcome. Carbapenem resistance was not a risk factor for mortality. According to a multivariable Cox proportional hazards model, age cutoff of 40 years (p = 0.016, HR 3.21), GCS score cutoff of 8 (p = 0.006, HR 0.29), CSF WBC count > 200 cells/mm3 (p = 0.01, HR 2.76), presence of EVD (p = 0.001, HR 5.42), and comorbidities (p = 0.017, HR 2.8) were found to be significant risk factors for mortality. CONCLUSIONS: This study is the largest case series reported to date of postneurosurgical Acinetobacter meningitis/ventriculitis. In-hospital mortality due to Acinetobacter meningitis/ventriculitis was high. Age older than 40 years, GCS score less than 8, presence of EVD, raised CSF WBC count, and presence of comorbidities were risk factors for mortality.

INTRODUCTION: Hemifacial spasm (HS) is a rare disorder caused by the compression of facial nerve root exit zone (REZ) at the brainstem by a vascular loop. Microvascular decompression (MVD) is a popular treatment modality for HS. OBJECTIVE: The purpose of this study was to determine the long-term efficacy and safety of MVD for HS by assessing the effect of the procedure from the literature published over the last 25 years. MATERIALS AND METHODS: A systematic data review from 1992 to 2015 using specific eligibility criteria yielded 27 studies on MVD for HS, the data of which were pooled and subjected to a meta-analysis. RESULTS: The pooled odds ratio (OR) revealed by the meta-analysis showed that anterior inferior cerebellar artery was the most common offending vessel in 37.8% (95% confidence interval [CI]: 27.8-47.7%) of the patients. Complete resolution of HS was seen in 88.5% (95% CI: 86.7-90.4%) of the patients after a long-term follow up. The complication rate was low following MVD, the most common being temporary facial paresis in 5.9% (95% CI: 4.3-7.5%) of patients. CONCLUSIONS: MVD is a safe and effective treatment for HS with long-term benefits and a low complication rate.

BACKGROUND: The trend in the outcome of patients with acute pancreatitis (AP) as a result of evolving management practices is not known. OBJECTIVE: To study and compare the outcomes of patients with AP at a tertiary care academic center over a period of 16 years. METHODS: In a retrospective study on a prospectively acquired database of patients with AP, we analyzed time trends of severity and mortality of AP. The influence of determinants of severity [APACHE II score, organ failure (OF), infected pancreatic necrosis (IPN)], and management strategy on the actual and predicted mortality was assessed. The actual mortality was adjusted for severity to analyze the severity-adjusted mortality at different times as a reflection of management practices over time. RESULTS: A total of 1333 patients were studied. The number of patients hospitalized with AP has been increasing over time. The proportion of patients with severe AP also increased from 1997 to 2013 as shown by increasing incidence of organ failure and IPN (Spearman's rank correlation coefficient (ρ): OF ρ(17) = 0.797, p < 0.01; IPN ρ(17) = 0.739, p < 0.001), indicating an increasing referral of sicker patients. Consequently, the overall mortality has been increasing (ρ(17) = 0.584; p = 0.014). However, despite increasing severity of AP, the mortality adjusted for OF has decreased significantly (ρ(17) = -0.55, p = 0.02). CONCLUSION: Even with increasing proportion of patients with severe AP, there has been a significant decrease in organ failure adjusted mortality due to AP suggesting improved management over years.

BACKGROUND AND AIMS: Inflammatory head mass of pancreas (IMP) developing in background of chronic pancreatitis (CP) is difficult to distinguish from carcinoma pancreas. We aimed to delineate natural course of IMP and predict their malignancy risk, avoiding unnecessary biopsies. MATERIALS AND METHODS: In this retrospective single-center study, clinical records of patients with CP with diagnosed pancreatic head mass were reviewed. Clinical, laboratory, imaging, endoscopic findings, and follow-up details were retrieved from prospectively maintained database. A diagnostic nomogram was developed combining serum cancer antigen 19-9 and endoscopic ultrasound (EUS) findings to predict the risk of malignancy. RESULTS: We identified 107 patients with pancreatic head mass with CP of whom 87 (81.3%) were IMP and 20 (18.7%) were malignant. Patients with IMP were more frequently young males with alcohol-related CP and low CA 19-9 in comparison with those with malignancy (age IMP: 41.3 ± 11.3 vs carcinoma: 49.3 ± 14.5 years [ P = 0.009]; males 89.7% vs 65% [ P = 0.011]; alcoholic etiology: 71.3% vs 20% [ P < 0.001]; median CA 19-9: 25.78 [interquartile range, 7.20-120.60] vs 1034.50 [106.65-7808.25] [ P < 0.001]). A diagnostic nomogram combining CA 19-9 and EUS findings could identify malignancy with an optimism-corrected c-statistic of 0.905, which was better than both CA 19-9 (0.80) and EUS alone (0.826). Patients with IMP had relatively benign disease course with 40.2% biliary obstruction, 20.7% portal venous thrombosis, 14.9% gastric outlet obstruction, and 1-, 3-, and 5-year survival being 97.3%, 92.7%, and 92.0%, respectively. Surgery was required in only 12 patients (13.8%) with IMP. CONCLUSIONS: Combination of CA 19-9 and EUS best identifies malignancy risk in patients with IMP, who have otherwise benign course.
