Single-Versus Multiple-Dose Antimicrobial Prophylaxis in Peroral Endoscopic Myotomy: A Randomized Controlled Study (SMAPP Trial).

Infections are uncommon after peroral endoscopic myotomy (POEM) procedure. However, prophylactic antibiotics are routinely administered for variable duration during peri-operative period. In this study, we aimed to determine the difference in the rate of infections between single (SD-A) and multiple doses (MD-A) antibiotic prophylaxis groups. The study was a prospective, randomized, non-inferiority trial conducted at a single tertiary care centre from Dec 2018 to Feb 2020. Eligible patients undergoing POEM were randomized into SD-A and MD-A groups. SD-A group received one dose of antibiotic (IIIrd gen cephalosporin) within 30-min of POEM. In the MD-A group, the same antibiotic was administered for a total of three days. Primary aim of the study was to determine the incidence of infections in the two groups. Secondary outcomes included incidence of fever (> 100 °F), inflammatory markers [erythrocyte sedimentation rate (ESR), c-reactive protein(CRP)], serum procalcitonin and adverse events related to antibiotics. (NCT03784365). 114 patients were randomized to SD-A (57) and MD-A (57) antibiotic groups. Mean post-POEM CRP (0.8 ± 0.9 vs 1.5 ± 1.6), ESR (15.8 ± 7.8 20.6 ± 11.7) and procalcitonin (0.05 ± 0.04 0.29 ± 0.58) were significantly higher after POEM (p = 0.001). Post-POEM inflammatory markers (ESR, CRP and procalcitonin) were similar in both the groups. Fever on day-0 (10.5% vs 14%) and day-1 (1.7% vs 3.5%) was detected in similar proportion of patients. Post-POEM infections were recorded in 3.5% (1.7% vs 5.3%, p = 0.618). Single dose of antibiotic is non-inferior to multiple dose antibiotic prophylaxis. Elevation of inflammatory markers and fever after POEM represents inflammation and does not predict infection after POEM.

Hemosuccus Pancreaticus: A systematic approach.

BACKGROUND AND AIM: Hemosuccus pancreaticus is considered as one of the rare cause of upper gastrointestinal bleeding. Intermittent nature of bleeding and lack of standardized approach for diagnosis has resulted in significant delay in definitive management. METHODS: We retrospectively analyzed prospectively maintained data of patients with suspected hemosuccus pancreaticus between January 2010 and December 2019. RESULTS: Out of 114 patients, 87 patients were diagnosed with hemosuccus pancreaticus. Mean age was 35.7 ± 11.7 years with 89.7% men. Median duration of bleeding before diagnosis was 10 days, with 40.2%, 10.3%, and 5.7% patients had symptoms beyond 1, 6, and 12 months, respectively. Visceral artery aneurysm was noted in 62% of cases with splenic artery aneurysm (37.9%) being the common source of bleed. Rarer causes noted were superior mesenteric artery aneurysm, pancreatic adenocarcinoma, gastrointestinal stromal tumor, and post-endoscopic retrograde cholangiopancreatography (2.3% each). Santorinirrhage was seen in 3.4% patients. Endoscopic diagnosis was possible in 64.4% of patients, and angiogram localization of bleeding source was noted in 94.2%. A 56.3% of patients underwent conventional angioembolization with 95.9% success and 28.7% underwent surgery, with overall rebleeding rate of 11.5%. CONCLUSIONS: Early diagnosis of hemosuccus pancreaticus avoids prolonged suffering, multiple hospital admissions, and multiple blood transfusions. It is not uncommon in the absence of aneurysm. In cases of high suspicion, repeating the endoscopy with proper technique and proper timing increases the yield. Angioembolization remains the most preferred first line therapeutic approach in majority of cases.

Indian Adolescent Living with HIV-AIDS: Current Clinical Scenario.

INTRODUCTION: Statistics suggest that, HIV has now largely become the disease of young patients. Hence, the adolescent HIV/AIDS needs to be handled and managed separately from adult HIV. Relatively fewer Indian data exist to characterize the associations in adolescents and young adults infected with HIV disease. The present study explores the current challenges in the management of HIV infected adolescents. OBJECTIVE: The study was aimed at evaluating, relationship between CD4 count and duration of antiretroviral therapy (ART), effects of ART on body mass index and the adverse effects of antiretroviral drugs in adolescent HIV positive patients. METHODS: This was a cross-sectional study involving 60 HIV positive adolescent patients attending tertiary care Institute KEM Hospital, Parel over duration of one year conducted at Mumbai. Patients on ART between age group 12 to 19 years. ART naïve patients were excluded from the study. RESULTS: 60 adolescent HIV positive patients attended our OPD including 37 males (61.67%) and 23 females (38.33%).The most common mode of transmission was vertical (80%). Education level was: school dropouts - 15%, primary education - 30%, Completed SSC - 31.7%, higher secondary - 23%. Among ADRs were 12 (63.15%) cases of anaemia due to Zidovudine, 4 (21.05%) hepatitis due to Nevirapine, 2 (10.52%) Tenofovir induced AKI and 1 (5.26%) Nevirapine rash. Wilcoxon matched pairs test showed a highly significant increase in the BMI (p <0.0001) post therapy. The mean CD4 of the patients at baseline and current presentation was 295.57 ± 109.81 and 630.93 ± 188.70 cells/mm3 respectively. The CD4 count was seen to be increasing with the increase in the duration of HAART treatment. CONCLUSIONS: High efficacy of HAART and availability of free ART under government programme has increased the duration of survival of the adolescent population with HIV. Treatment with HAART showed a favourable response with a statistical significant increase in CD4 count. Longer the duration of HAART, higher was the gain in CD4 count. Indian adolescent receiving long term ART, Lipodystrophy is not a troubling issue. Indian adolescent seems to be more tolerance of ART than the other parts of world.

Fractional Excretion of Sodium and Urea in Differentiating Acute Kidney Injury Phenotypes in Decompensated Cirrhosis.

Background: Prerenal acute kidney injury (prerenal AKI), hepatorenal syndrome (HRS-AKI), and acute tubular necrosis (ATN-AKI) are the various phenotypes of acute kidney injury, which are described in decompensated cirrhosis. It has therapeutic and prognostic implications. We aimed to evaluate the diagnostic utility of fractional excretion of sodium and urea (FENa and FEUrea) for differentiating AKI phenotypes. Methods: A prospective analysis was performed in 200 patients with decompensated cirrhosis with AKI to derive receiver operating curve, optimal cut-off, sensitivity, and specificity. These findings were validated in an independent cohort (n = 50) to differentiate ATN-AKI, HRS-AKI, and prerenal AKI. Results: The incidence of prerenal AKI, HRS-AKI, and ATN-AKI were 37.5%, 34%, and 28.5% in the derivation cohort and 28%, 38%, and 34% in the validation cohort respectively. The median FENa was significantly different in various phenotypes of AKI in the derivation and validation cohort (P 0.001); FEUrea was significantly different in the derivation cohort (P 0.0001), not in the validation cohort (P 0.106). The AUC for FENa (cut-off, sensitivity/specificity) was 86.6% (0.567, 89/71) and for FEUrea was 60.3% (34.73, 70/58) for ATN-AKI vs. non-ATN-AKI. The area under the curve for FENa to differentiate between HRS-AKI vs. non-HRS-AKI was 74.5%. FEUrea could not differentiate HRS-AKI vs. non-HRS-AKI (AUC 60.4%) satisfactorily. FENa and FEUrea were unable to differentiate between prerenal AKI and HRS-AKI (AUC <70%). Conclusion: Among cirrhotics FENa at admission is a simple, commonly available clinical tool that can be used to differentiate structural AKI from prerenal AKI and HRS-AKI. The newly derived lowered cut-off value of FENa makes the diagnosis of ATN-AKI easier, faster and thus obviates the need for extensive workup in a significant proportion of patients. FENa appears better than FEUrea in decompensated cirrhosis with AKI.
