Coagulopathy and D-dimer level among 114 patients with CLD and cirrhosis were evaluated in this study. they were classified according to Child-Pugh score into A, B and C; and encountered in 10.5%, 26.3%, and 63.2% of total patients respectively. by the way, Baker et al. studied Child-Pugh score as predictor of short-term prognosis in Bangladesh, 2021 and found the incidence of Child-Pugh score A, B, and C was 8%, 28%, and 64% respectively(Baker et al., 2022) while Kumar, et al., studied Child-Pugh score as a better predictor of mortality than MELD in Karachi, 2018 among 165 patients, and reported that, Child's Class A, B, and C showed in 1.21% 38.65%, and 60.60% respectively(Kumar et al., 2018).
In this study, male more affected than female, 63.2% vs 36.8% of total patients and this came in concordance with 68.5% vs 31.5% reported by Kumar et al, and 56.7% vs 43.3% reported by Siddiqui et al(Kumar et al., 2018; Siddiqui et al., 2011). However, gender-specific distribution of patients among Child-Pugh score were nearly equal and as a reflection of their total percentages.
The age 40 years divided the affected patients into two halves. And, 72.2% of Child-Pugh C patients were younger (< 40 years old). On the other hand, 100% of Child-Pugh A, 86.7% of Child-Pugh B patients were 40 years old or older (P Value < 0.001**). By comparison, Siddiqui et al reported that 53.8% were older than 45 years old with male affected more than female.
All patients were Khat chewers. Khat chewing is unique habits for Yemeni and some African nations such as Ethiopian and Somalian. In this scope, Khat induced hepatitis is considered more recently as unique entity, in others words, disease per se and still in scope of research, however, some postulate that Khat triggers hepatitis either from toxin effect or drugs abuse or in just an immune susceptible patients and by the way, AIH relapse recurrent by Khat Chewing(Al Haj et al., 2020; Orlien et al., 2018).
In this study, 17.5% of total patients were active smokers with a difference of statistically significance among Child-Pugh scores regarding smoking habits, all active smokers were in Child-Pugh C (P value 0.001*). in literature review, A history of smoking is observed in approximately 40% of patients with liver disease. Clinical evidence indicates that cigarette smoking negatively impacts the incidence and severity of CLD at multiple levels: cigarette smoking promotes hepatocarcinogenesis, represents a hepatic fibrogenic stimulus, exacerbates metabolic fatty liver diseases and negatively impacts liver-related outcomes at cellular, histologic, systemic, and clinical layer respectively.(Ellerbeck et al., 2018; Marti-Aguado et al., 2022; Orlien et al., 2018; Rutledge & Asgharpour, 2020)
Etiology of CLD and cirrhosis were known among most of our patients: autoimmune hepatitis, HBV, Bilharziasis, HCV accounting of 36.8%, 21.1%, 12.3% and 7% of total patients respectively. However, 22.8% of total patients were surprisingly of unknown etiology. By combining of AIH and Unknown etiology together, they constituted more than 50% of causes and hence we can recall Khat chewing effects as previously detailed and supported by many published papers. By the way, while viral hepatitis either B or C or coinfection were recognized as the main cause of CLD by Siddiqui et al, 10% was of unknown cause and AIH was not reported. This is indirectly going with the effect of Khat chewing in countries where chewing Khat habit well recorded.
Increased fatiguability was in every patient. Others presented symptoms were, Distended abdomen (ascites and splenomegaly), Discoloration of the body (jaundice), GIT bleeding (hematemesis and melena), Change LOC (encephalopathy), and Anuria. accounting of 89.5%, 70.2%, 56.1%, 52.6% and 3.5% of total patients respectively.
In context of distended abdomen, abdominal USG confirmed the presence of ascites in 89.5%, and splenomegaly in 77.2% of total patients. These percentages in our study were a higher than 53.8%, and 66.1% which reported by Siddiqui et al respectively(Siddiqui et al., 2011). US is operator depended machine and the aim of each study may stand beyond these slight differences. Of note, presence of ascites and splenomegaly incrementally proportionated with Child-Pugh score; The higher score hence severity of disease, the higher percentage of ascites and splenomegaly, (P-vale < 0.001**). By the same side, Jaundice and encephalopathy recognized among 70.2% and 52.6% which were higher than 48.5%, and 30.4% of total patients reported by Siddiqui et al(Siddiqui et al., 2011) respectively. on the opposite side, GI bleeding found among 56.1%of total in this study which was slightly lower than 71.9% which reported by(Siddiqui et al., 2011)
Although bleeding events found in direct proportion with stage of liver disease, - the higher stage then severity, the higher bleeding events-, esophageal varices of grade 3 to 4 discovered in all patients of Child-Pugh A and B while only in 83.3% of Child-Pugh C of them 66.7% in the same grade. So, GIT bleeding rather than presence of esophageal varices of any grade responsible of decompensation and severe stage of CLD. High portal pressure, thrombocytopenia, decrease production of coagulation factors (elevated PT/INR) and increased tissue plasminogen level are factors come in favors of bleeding tendency. (Valla et al., 2014) In this context, platelets count ranged between 26–216(130.5), 115–198(174), 56–163(131), and 26–216(129) of total, Child-Pugh A, B and C respectively. All thrombocytic patients below 50k found only in Child-Pugh C, while those who had platelets count bellow 100k but > 50k found in C and B. This result in consistent with most previously mentioned studies in the literature(Fadyla et al., 2021).
Many pathophysiological mechanisms can explain thrombocytopenia in CLD such as increased splenic pooling, shortened life span due increased splenic destruction, increased antibody mediated platelet destruction, relative bone marrow insufficiency, and decreased thrombopoietin secretion. (Valla & Rautou, 2015)
Similarly, PT(seconds) prolonged among 94.7% of total patients and it ranged between 15–50(18), 17–18(18), 15–18(16.5), and 17–50(23.75) and INR(%) ranged between 1.13–3.8(1.4), 1.2–1.4(1.4), 1.13–1.4(1.4), and 1.3–3.8(1.8) for total, Child-Pugh A, B, and C respectively. So, it was clear that, the median of PT/INR in Child-Pugh C patients were prolonged/elevated while that of Child-Pugh A and B were slightly elevated or nearly normal. Although 90.6% of GIT bleeding had prolonged PT/INR and 9.4% had normal PT/INR values, the last presented in decompensated stages B and C. So, advanced CLD stages may predict bleeding events even with normal PT/INR value, this agreed with Tripodi et al(Tripodi et al., 2010; Tripodi, Primignani, Chantarangkul, Viscardi, et al., 2009).
However, many factors come in favors of thrombotic tendency Low portal venous blood flow, Immobilization-related venous stasis, Increased vW factor level, increased high molecular weight vW factor levels (decreased ADAMTS13 levels) Decreased antithrombin, protein C and protein S level, Increased factor VIII levels, decreased plasminogen, factor XIII, a2 antiplasmin and TAFI levels, and Increased PAI-1 levels.(Valla & Rautou, 2015)
Of these factors D-dimer was measured and found in direct proportion with stage of liver disease, the higher stage then severity of liver disease, the higher D-dimer level. D-dimer ranged between 320-10000(5127), 320–560(460), 950–8870(1800), and 1143–10000(6200) for total, Child-Pugh A, B, and C respectively. of note, D-dimer of Child-Pugh patients based on normal cut off point of 500. On the other hand, patients in Child-Pugh B and C groups showed high D-dimer levels. furthermore, there were strong positive correlation between elevated D-dimer and severity of the disease. In the context, elevated D-dimer among CLD and cirrhotic liver is well known in literatures, Primignani et al. (2017), Dhanunjaya et al. Wesam A. Ibrahim, Sara Abdelhakam et al. in 2011,. Spadero et al. and (Al-Basheer & Humeida, 2017). moreover, Dhanunjaya et al, found that was to be strongly increased significantly with severity of liver disease. on the other hand, Apart of high D-dimer levels and the time of sample recruitment for this study which was during 1st pandemic episode of COVID-19, there was no thrombotic event, however the possibility of infection with and effect of COVID-19 can’t be excluded.
Our study showed a statistically significant negative correlation of D dimer levels with albumin level R-Value (-0.415) P-Value < 0.001**. And positive correlation with bilirubin level R-Value (0.44) P-Value = 0.009**, ascites R-Value (0.372) P-Value < 0.001** and Child-Pugh points R-Value (0.401) P-Value < 0.001**. These correlations came in concordance with Wesam A. Ibrahim, Sara Abdelhakam et al(Ibrahim et al., 2015). Surprisingly there were no statistically significant D-dimer correlations with platelets count, Prothrombin time and INR in patients with CLD and this disagree with Wesam A. Ibrahim, Sara Abdelhakam et al.
