Granulocyte colony stimulating factor: A potential therapeutic rescue in severe alcoholic hepatitis and decompensated cirrhosis

Liver cirrhosis accounts for over 2 million deaths annually worldwide. A subset of these patients – those with alcoholic hepatitis and decompensated cirrhosis, have abysmal short-term survival. Liver transplant is the only intervention of proven survival benefit; however organ availability is a major limitation. It is thus imperative to assess potential benefit of experimental therapies as a bridge to transplant.Stem cell therapies have shown some promise in patients with end-stage liver disease. Of these, bone-marrow derived hematopoietic stem cells have generated the most interest. Animal as well as human data suggest biological plausibility of stem cell translocation from bone marrow to liver, giving credence to cytokine therapies based on bone marrow stimulation. Granulocyte colony stimulating factor has been the most frequently used cytokine for this purpose. This intervention has shown encouraging results in terms of safety as well as survival benefits in small clinical trials. The evidence, however, is sparse and heterogeneous.In this review we describe the biological plausibility, mechanisms of action, and clinical evidence of the use of cytokine based stem cell therapy in patients with end-stage liver disease

Unusual presentation of Kallmannn syndrome with contiguous gene deletion in three siblings of a family

We report the case of 3 brothers aged 34, 24, and 22 years, unmarried, who presented to our endocrinology clinic with absence of secondary sexual characters. There was no such history in other siblings, but their maternal uncle had similar complaints. On examination, all 3 had pre-pubertal appearance, voice, and genitalia along with anosmia and bimanual synkinesia. Cryptorchidism was noticed in 2 while third person had small hypoplastic testes. It was also noted that all 3 patients had icthyosis mainly involving trunk, back, and limbs. The hormonal assays were consistent with isolated hypogonadotrophic hypogonadism. IQ testing revealed mental retardation in the 2 patients. Ultrasound showed ectopic right kidney in one patient, atrophic right kidney in the second patient while the third patient had normal kidneys. MRI brain of all the patients showed poorly visualized olfactory tract and bulb. Kallmann syndrome (KS) was diagnosed based on hormonal evaluation and MRI results. Of the four types of KS: Synkinesia, renal anomaly, and X-linked pedigree pattern in our patients pointed towards X-linked type 1 KS as the possible cause. But, icthyosis and mental retardation are not usual presentation of type 1 KS. They are usually seen as a result of contiguous gene deletion of KAL1, steroid sulfatase (STS), and mental retardation (MRX) gene on X chromosome. Hence, the possible gene defect in our cases is inherited defect in contiguous gene deletion. The contiguous gene deletion as the cause of KS in 3 patients of same family is very rare and worth reporting. Also, the significance of phenotype-genotypic association in Kallmann syndrome is discusse

Public awareness of acetaminophen and risks of drug induced liver injury: Results of a large outpatient clinic survey.

Acetaminophen is one of the most commonly consumed analgesics world wide. Generally perceived as a safe medication, it is the most common cause of acute liver failure in the United States with inadvertent hepatotoxicity in half of all cases. We therefore conducted a survey on the public perceptions of acetaminophen in patients attending the outpatient clinic in Vancouver, Canada. Among 928 patients who were asked, 765 completed the survey questionnaire. The majority of respondents were female (59%), Caucasian (61%), and educated beyond the secondary school level (81%). 23% reported using acetaminophen at least once a week. A significant minority were unaware of the potential liver toxicity of acetaminophen (24%), and knowledge of hepatotoxicity did not vary with education status. In terms of the medicinal composition of acetaminophen products, over half of the respondents (58%) did not know that extra strength preparations of acetaminophen contained the same drug but in a different dose. This knowledge was more prevalent among those with higher level of education (49% in graduate school educated respondents), but was still low overall. The knowledge that alcohol use with acetaminophen was more harmful was low (43%), but improved with level of education (P for trend 0.03). Among respondents who consumed alcohol regularly, 21% were consuming over 1.5 grams of acetaminophen at a time. These patients had similar harm perception to liver as patients who consumed lower doses of acetaminophen. Overall, in a large, well-educated cohort of patients, knowledge about the adverse effects of acetaminophen, the additional risks with alcohol and composition of various retailed products was suboptimal. We speculate that consumer ignorance is a significant reason why acetaminophen is a leading cause of acute liver failure

Acute Liver Failure Due to Etodolac, a Selective Cycloxygenase- 2 (COX -2) Inhibitor Non-Steroidal Anti-Inflammatory Drug Established by RUCAM-Based Causality Assessment

Drug induced liver injury is a common cause of acute liver failure (ALF). While most of these cases are due to dose dependent hepa-totoxicity with acetaminophen, idiosyncratic drug-induced liver injury (DILI) is responsible for about 15% cases of ALF. Antibiotics are the most common cause of idiosyncratic DILI as well as DILI induced ALF. Etodolac is a selective cycloxygenase- 2 (COX -2) inhibitor non-steroidal anti-inflammatory drug used as an analgesic and anti-inflammatory in musculoskeletal diseases. Severe liver impairment is extremely rare. Till date, only 3 cases of ALF related to etodolac have been reported in the literature. Here we report two cases with a unique presentation of ALF occurring due to DILI caused by etodolac, as diagnosed by Roussel Uclaf Causality Assessment Method (RUCAM)

Survival of Trial-Like and Non–Trial-Like Patients With Immunotherapy in Advanced Hepatocellular Carcinoma in Real World: A Collaborative Multicenter Indian Study (IMHEP)

PURPOSEImmune checkpoint inhibitors (ICIs) is the initial line of management in advanced hepatocellular carcinoma (HCC), but survivals in the real world are not known.MATERIALS AND METHODSA retrospective study of patients with advanced HCC receiving ICIs (as first-line therapy or as later lines of therapy) across 11 Indian institutions was conducted. Patients were divided into either cohort 1 (trial-like receiving ICI as first-line therapy), with a Child Pugh score (CTP) of ≤6, an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0/1, and no VP4 (main portal vein thrombosis [MPVT]) or cohort 2 (trial unlike) who did not satisfy at least one of the above criteria. The primary end point was 12-month overall survival (OS).RESULTSBetween January 2017 and January 2022, 133 patient data were analyzed. The presence of MPVT was seen in 33 patients (25%). The ICIs used were atezolizumab-bevacizumab, nivolumab, and pembrolizumab in 89 (66%), 44 (33%), and one (1%) patients, respectively. With a median follow-up of 13.8 months, the 12-month OS for the entire cohort was 33.4% (95% CI, 23.6 to 43.2). Patients in cohort 1 (n = 31) had a significantly improved OS compared with patients in cohort 2 (n = 102; 12-month OS, 57.9% [95% CI, 38.5 to 77.3] v 24% [95% CI, 13.4 to 34.6]; P = .005). Patients with CTP A as compared with CTP B (9.7 v 4.3 months; P < .001) and an ECOG PS of 0/1 as compared with a PS of ≥2 (8.7 v 7.2 months; P = .04) and without MPVT (9.4 v 4.0; P < .001) had superior survivals.CONCLUSIONPatients with advanced HCC in the real world, trial-like have survivals in consonance with trial data, whereas patients with features excluding them from trials, such as main portal vein thrombosis, poor ECOG PS, and child Pugh B status, have markedly inferior survivals, despite good tolerance to immunotherapy
