RESUMO

Extrahepatic portal vein thrombosis (EHPVO) is an uncommon cause of portal hypertension. In the long term, patients may develop portal cavernoma cholangiopathy (PCC). Up to 30%-40% of patients with EHPVO may not have shuntable veins and are often difficult to manage surgically. Interventional treatment including portal vein recanalisation-trans jugular intrahepatic portosystemic shunt (PVRecan-TIPS) has been used for patients with EHPVO. However, PV reconstruction-trans jugular intrahepatic portosystemic shunt (PVRecon-TIPS) and portal vein stenting are novel techniques for managing such patients with EHPVO with non-shuntable venous anatomy. In contrast to PVRecan-TIPS, PV reconstruction-TIPS (PVRecon-TIPS) is performed through intrahepatic collaterals. Here we present six cases of PCC who presented with recurrent acute variceal bleeding (AVB) and or refractory biliary stricture. They did not have any shuntable veins. PVRecon-TIPS was performed for five patients whilst PV stenting was done in one. Amongst the six patients, one died of sepsis whilst one who developed hyponatremia and hepatic encephalopathy was salvaged with conservative management. Following the procedure, they were started on anti-coagulation. Decompression of cavernoma was documented in all other patients. Biliary changes improved completely in 40% of patients.

RESUMO

We present two cases which underwent complex ocular surface reconstruction to achieve a stable ocular surface. Conjunctival autograft (CAG) procedure was required more than once, in addition to simple limbal epithelial transplantation to address extensive symblepharon in the eyes with total unilateral limbal stem cell deficiency secondary to acid ocular burns. These cases demonstrate that multiple CAGs may be harvested from the contralateral unaffected eye to correct recurrent symblepharon without any donor site complications if the correct surgical technique is adopted.

RESUMO

This review analyzed all pertinent articles on keratoconus (KCN) and cataract surgery. It covers preoperative planning, intraoperative considerations, and postoperative management, with the aim of providing a simplified overview of treating such patients. Preoperatively, the use of corneal cross-linking, intrastromal corneal ring segments, and topo-guided corneal treatments can help stabilize the cornea and improve the accuracy of biometric measurements. It is important to consider the advantages and disadvantages of traditional techniques such as penetrating keratoplasty and deep anterior lamellar keratoplasty, as well as newer stromal augmentation techniques, to choose the most appropriate surgical approach. Obtaining reliable measurements can be difficult, especially in the advanced stages of the disease. The choice between toric and monofocal intraocular lenses (IOLs) should be carefully evaluated. Monofocal IOLs are a better choice in patients with advanced disease, and toric lenses can be used in mild and stable KCN. Intraoperatively, the use of a rigid gas permeable (RGP) lens can overcome the challenge of image distortion and loss of visual perspective. Postoperatively, patients may need updated RGP or scleral lenses to correct the corneal irregular astigmatism. A thorough preoperative planning is crucial for good surgical outcomes, and patients need to be informed regarding potential postoperative surprises. In conclusion, managing cataracts in KCN patients presents a range of challenges, and a comprehensive approach is essential to achieve favorable surgical outcomes.

RESUMO

Background: Cancer screening utilization can aid in the early diagnosis and treatment of cancer. However, the current scenario of the knowledge and practice regarding cancer screening remains unclear as the authors do not have sufficient studies. Hence, the authors conducted this systematic review and meta-analysis to assess the situation of cancer screening utilization and knowledge. Methods: A systematic literature review was conducted to identify all studies on knowledge and practice regarding cancer screening in the Nepalese population. Data extraction and analysis were done with SPSS and CMA-3. Results: The authors identified a total of 5238 studies after database searching, and 19 studies were included in a narrative synthesis. Lack of awareness and knowledge was the major barrier in cervical, breast, and testicular cancer screening. In cervical cancer screening, the most common reason for screening was the advice of health personnel in 85% of respondents, and the barrier was lack of awareness in 49.33% of participants. Conclusion: The knowledge and practice of cancer screening is lacking in Nepal, as shown by our review. More educational and awareness programs, easy access to screening services, and elimination of sociocultural barriers are necessary to increase the utilization of screening services.

RESUMO

Peroxisome proliferator-activated receptor-α (PPAR-α) belonging to the nuclear hormone receptor superfamily is a promising target for CVDs which mechanistically improves the production of high-density lipid as well as inhibit vascular smooth muscle cell proliferation. PPAR-α mainly interferes with adenosine monophosphate-activated protein kinase, transforming growth factor-ß-activated kinase, and nuclear factor-κB pathways to protect against cardiac complications. Natural products/extracts could serve as a potential therapeutic strategy in CVDs for targeting PPAR-α with broad safety margins. In recent years, the understanding of naturally derived PPAR-α agonists has considerably improved; however, the information is scattered. In vitro and in vivo studies on acacetin, apigenin, arjunolic acid, astaxanthin, berberine, resveratrol, vaticanol C, hispidulin, ginsenoside Rb3, and genistein showed significant effects in CVDs complications by targeting PPAR-α. With the aim of demonstrating the tremendous chemical variety of natural products targeting PPAR-α in CVDs, this review provides insight into various natural products that can work to prevent CVDs by targeting the PPAR-α receptor along with their detailed mechanism.

RESUMO

Introduction and importance: This case report highlights the multidisciplinary approach required to achieve successful anatomical and functional outcomes, in an eye with total limbal stem cell deficiency (LSCD) associated with underlying corneal scarring and thinning. Presentation of case: A 59-year-old gentleman had poor visual recovery in the right eye (RE) following accidental carbide blast, 1-year before presenting to us. The visual acuity was counting fingers and clinical examination revealed cicatricial entropion involving the upper eyelid, total LSCD, corneal scarring with a central descemetocele and cataract in the RE. Prior to ocular surface reconstruction, entropion correction was performed. Three months later, penetrating keratoplasty combined with cataract surgery and intraocular lens implantation (penetrating keratoplasty (PK) triple), with autologous simple limbal epithelial transplantation (SLET) was performed. The visual acuity was 20/100, 18 months after the surgery, with a clear well-epithelized corneal graft and stable ocular surface. Discussion: LSCD is caused by a decrease in the population and /or function of the limbal epithelial stem cells. Limbal stem cell transplantation (LSCT) is warranted in eyes with total LSCD. In eyes with coexisting corneal scarring, LSCT alone may be inadequate to restore the vision. These eyes require simultaneous or sequential lamellar or full-thickness corneal transplantation for visual rehabilitation. Though, the existing literature favors a sequential approach, where LSCT is performed first followed by corneal transplantation, under certain circumstances such as a thin underlying cornea like in our case, corneal transplantation may have to be combined with LSCT to achieve optimal outcomes. Conclusion: Combining autologous SLET with PK can be performed for visual rehabilitation in eyes with unilateral total LSCD and underlying corneal thinning. Corneal and limbal graft survival is prolonged if existing adnexal comorbidities are addressed before any surgical intervention is planned and adequate time interval is allowed for the surface inflammation to subside.

RESUMO

Purpose: To study and compare the demographic and clinical profile of acute ocular burns (AOB) in children and adults. Methods: This retrospective case series included 271 children (338 eyes) and 1300 adults (1809 eyes) who presented to two tertiary eye care centers within one month of sustaining AOB. Data regarding demographics, causative agents, severity of injury, visual acuity (VA), and treatment were collected and analyzed. Results: Males were more commonly affected particularly among adults (81% versus 64%, P < 0.00001). Among children, 79% sustained domestic injuries, whereas 59% of adults had work-place injuries (P < 0.0001). Most cases were due to alkali (38%) and acids (22%). Edible lime (chuna, 32%), superglue (14%), and firecrackers (12%) in children, and chuna (7%), insecticides, lye, superglue (6% each), toilet cleaner (4%) and battery acid (3%) in adults, were the main causative agents. The percentage of cases with Dua grade IV-VI was greater in children (16% versus 9%; P = 0.0001). Amniotic membrane grafting and/or tarsorrhaphy were needed in 36% and 14% of affected eyes in children and adults, respectively (P < 0.00001). The median presenting VA was logMAR 0.5 in children and logMAR 0.3 in adults (P = 0.0001), which improved significantly with treatment in both groups (P < 0.0001), but the final VA in eyes with Dua grade IV-VI burns was poorer in children (logMAR 1.3 versus logMAR 0.8, P = 0.04). Conclusion: The findings clearly delineate the at-risk groups, causative agents, clinical severity, and treatment outcomes of AOB. Increased awareness and data-driven targeted preventive strategies are needed to reduce the avoidable ocular morbidity in AOB.

RESUMO

PURPOSE: The aim of this study was to describe the presenting feature of vortex keratopathy in 3 patients with biopsy-proven ocular mucous membrane pemphigoid (OMMP). METHODS: The first patient was a 52-year-old woman with chronic redness and foreign body sensation for 3 years who presented with unilateral vortex keratopathy. Seven months later, in the same eye, she developed conjunctival signs suggestive of OMMP. The second patient was a 33-year-old woman with similar chronic symptoms that were exacerbated by pterygium surgery. Clinical examination revealed vortex keratopathy in the right eye with subtle conjunctival signs suggestive of OMMP. The third patient was a 70-year-old woman with complaints of repeated episodes of redness and foreign body sensation for 18 months who presented with vortex keratopathy in the right eye and conjunctival signs suggestive of OMMP in the same eye. To confirm the clinical diagnosis, bilateral conjunctival biopsy was performed in all patients. RESULTS: OMMP was diagnosed based on conjunctival signs and confirmed on direct immunofluorescence positivity, demonstrating antibodies characteristic and diagnostic of OMMP in the basement membrane zone. A unique feature that preceded or coexisted with the conjunctival signs was unilateral vortex keratopathy seen in all 3 patients, independent of the stage of the disease at which they presented. CONCLUSIONS: Vortex keratopathy can be a presenting feature in patients with OMMP. A complete ocular surface examination, especially checking the medial canthus for keratin and the inferior fornix for foreshortening, is necessary. Conjunctival biopsy should be performed in all cases to confirm the clinical diagnosis wherever required.

RESUMO

Backgrounds/Aims: Hemangiomas are the most common benign liver lesions; however, they are usually asymptomatic and seldom require surgery. Enucleation and resection are the most commonly performed surgical procedures for symptomatic lesions. This study aims to compare the outcomes of these two surgical techniques. Methods: A retrospective analysis of symptomatic hepatic hemangiomas (HH) operated upon between 2000 and 2021. Patients were categorized into the enucleation and resection groups. Demographic profile, intraoperative bleeding, and morbidity (Clavien-Dindo Grade) were compared. Independent t-test and chi-square tests were used for continuous and categorical variables respectively. p-value of < 0.05 was considered significant. Results: Sixteen symptomatic HH patients aged 30 to 66 years underwent surgery (enucleation = 8, resection = 8) and majority were females (n = 10 [62.5%]). Fifteen patients presented with abdominal pain, and one patient had an interval increase in the size of the lesion from 9 to 12 cm. The size of hemangiomas varied from 6 to 23 cm. The median blood loss (enucleation: 350 vs. resection: 600 mL), operative time (enucleation: 5.8 vs. resection: 7.5 hours), and postoperative hospital stay (enucleation: 6.5 vs. resection: 11 days) were greater in the resection group (statistically insignificant). In the resection group, morbidity was significantly higher (62.6% vs. 12.5%, p = 0.05), including one mortality. All patients remained asymptomatic during the follow-up. Conclusions: Enucleation was simpler with less morbidity as compared to resection in our series. However, considering the small number of patients, further studies are needed with comparable groups to confirm the superiority of enucleation over resection.

RESUMO

INTRODUCTION AND IMPORTANCE: The case report highlights the challenges in managing recurrent Mooren's ulcer, a rare and severe form of peripheral ulcerative keratitis. CASE PRESENTATION: A 49-year-old male, with bilateral Mooren's disease who underwent multiple surgical interventions for visual rehabilitation but developed disease recurrence in the left eye despite being on systemic and topical immunosuppression. The authors report successful long-term visual rehabilitation following a large-graft penetrating keratoplasty and Ahmed glaucoma valve implantation performed under immunosuppressive cover after adequate control of inflammation with intravenous Rituximab. CLINICAL DISCUSSION: We discuss the traditionally poor survival of penetrating keratoplasty in refractory Mooren's disease due to the recurrence of the disease in the graft. Occurrence of secondary glaucoma is commonly seen in these eyes, which often requires combined filtration surgery and medical management. The first and second line systemic immunosuppression may be insufficient in adequately controlling the disease, and that intravenous monoclonal antibodies, such as Rituximab, may be a promising treatment modality in refractory Mooren's disease prior to embarking on any surgical intervention. CONCLUSION: Overall, the case report highlights the importance of adequate control of inflammation and the use of immunosuppressive cover in achieving successful outcomes of PK and AGV surgery in Mooren's ulcer. The authors suggest that intravenous Rituximab may be a valuable addition to the management of refractory Mooren's disease, particularly prior to surgical intervention. However, as with any case report, the findings should be interpreted with caution and further research is needed to validate the efficacy of this treatment modality.

RESUMO

Bilateral corneal blindness with severe dry eye disease (DED), total limbal stem cell deficiency with underlying corneal stromal scarring and vascularization, combined with adnexal complications secondary to chronic cicatrizing conjunctivitis is a highly complex situation to treat. In such eyes, procedures such as penetrating keratoplasty alone or combined with limbal stem cell transplantation are doomed to fail. In these eyes, keratoprosthesis (Kpro) or an artificial cornea is the most viable option, eliminating corneal blindness even in eyes with autoimmune disorders such as Stevens-Johnson syndrome, ocular mucous membrane pemphigoid, Sjogren's syndrome, and nonautoimmune disorders such as chemical/thermal ocular burns, all of which are complex pathologies. Performing a Kpro in these eyes also eliminates the need for systemic immunosuppression and may provide relatively early visual recovery. In such eyes, the donor cornea around the central cylinder of the Kpro needs to be covered with a second layer of protection to avoid desiccation and progressive stromal melt of the underlying cornea, which is a common complication in eyes with severe DED. In this review, we will focus on Kpro designs that have been developed to survive in eyes with the hostile environment of severe DED. Their outcomes in such eyes will be discussed.

RESUMO

Early diagnosis of cryptococcal meningitis among people living with HIV (PLHIV) is crucial for its therapeutic success. The objective of this study was to diagnose cryptococcal meningitis in PLHIV cases using the available laboratory techniques for its confirmation in resource limited setting. This cross-sectional prospective study was conducted among 72 PLHIV with clinical suspicion of meningitis. Each cerebrospinal fluid (CSF) sample received at the National Public Health Laboratory, Kathmandu was processed for India ink staining, cryptococcal antigen lateral flow assay, and fungal culture following standard protocols. The laboratory-confirmed cryptococcal meningitis cases were between 24 and 69 years of age (median age 39 years) with 87.5% (12/14) of cases being male. Cryptococcus was detected in 22.22% (16/72) by any of the three tests, 19.44% (14/72) by cryptococcal antigen lateral flow assay, 16.66% (12/72) by India ink staining, and 8.33% (6/72) by culture. High percentage of cryptococcal meningitis among PLHIV warrants early microbiological diagnosis for better case management. Cryptococcal antigen detection immunoassay should be the priority test for laboratory diagnosis of cryptococcal meningitis in PLHIV. Alternatively, very simple and economic India ink staining of CSF specimens could be used in resource limited settings.

RESUMO

Malaria is still a global challenge with significant morbidity and mortality, especially in the African, South-East Asian, and Latin American regions. Malaria diagnosis is a crucial pillar in the control and elimination efforts, often accomplished by the administration of mass-scale Rapid diagnostic tests (RDTs). The inherent limitations of RDTs- insensitivity in scenarios of low transmission settings and deletion of one of the target proteins- Histidine rich protein 2/3 (HRP-2/3) are evident from multiple reports, thus necessitating the need to explore novel diagnostic tools/targets. The present study used peptide microarray to screen potential epitopes from 13 antigenic proteins (CSP, EXP1, LSA1, TRAP, AARP, AMA1, GLURP, MSP1, MSP2, MSP3, MSP4, P48/45, HAP2) of P. falciparum. Three cyclic constrained immunoreactive peptides- C6 (EXP1), A8 (MSP2), B7 (GLURP) were identified from 5458 cyclic constrained peptides (in duplicate) against P. falciparum-infected sera. Peptides (C6, A8, B7- cyclic constrained) and (G11, DSQ, NQN- corresponding linear peptides) were fairly immunoreactive towards P. falciparum-infected sera in dot-blot assay. Using direct ELISA, cyclic constrained peptides (C6 and B7) were found to be specific to P. falciparum-infected sera. A substantial number of samples were tested and the peptides successfully differentiated the P. falciparum positive and negative samples with high confidence. In conclusion, the study identified 3 cyclic constrained immunoreactive peptides (C6, B7, and A8) from P. falciparum secretory/surface proteins and further validated for diagnostic potential of 2 peptides (C6 and B7) with field-collected P. falciparum-infected sera samples.

RESUMO

Ashish SinghBackground Regarding gallbladder cancer (GBC) there is conflicting evidence in the literature whether retroperitoneal lymph nodal metastases (RLNM) should be considered as regional nodal metastasis or as distant metastasis (DM) and the jury is out on radical curative surgery in presence of RLNM. This is an analysis of GBC patients, to see the effect of RLNM on survival and to compare with that of patients with DMs. Methods A retrospective analysis of a prospective database of patients of GBC with RLNM (interaortocaval and paraaortic) or DM on frozen section biopsy at surgery, between January 2013 and December 2018. Data was analyzed using the Statistical Package for the Social Sciences software (version 22.0). Survival in these two groups (RLNM and DM) was compared with log-rank test. A p -value of < 0.05 was considered significant. Results A total of 235 patients with ostensibly resectable GBC underwent surgical exploration. The planned curative resection was abandoned in 91 (39%) patients because of RLNM ( n = 20, 9%) or DM ( n = 71, 30%) on frozen section biopsy. Demographic profile and blood parameters were similar. The median survival for RLNM and DM groups were 5 (range 2-26) and 6 (range 2-24) months, respectively, with no significant difference on log-rank test ( p = 0.64). There was no 3-year or longer survivor in either group. Conclusion Due to similar poor survival in presence of RLNM or DM, RLNM should be considered as the equivalent of DM. This study strengthens evidence to avoid curative surgery in patients with RLNM. These lymph nodes should be sampled preoperatively, if suspicious on imaging, for fine-needle aspiration cytology and at surgery, as a routine for frozen section histological examination before initiating curative resection to avert a futile exercise.

RESUMO

INTRODUCTION: arachnoid cyst-associated subdural fluid collections have been documented in children and adults following traumatic brain injury (TBI). However, this phenomenon has not been previously demonstrated in infants less than 12 months of age. We present a case of an infant with bilateral arachnoid cyst-associated subdural fluid collections identified after TBI. CASE PRESENTATION: a 9-month-old female infant with profound macrocephaly presented to medical care with altered mental status following a witnessed fall down steps while unsecured in a stroller. Neuroimaging revealed bilateral subdural fluid collections, in addition to a hyperdense subdural hematoma, that raised concern for abusive head trauma (AHT) among the pediatric inpatient team and the hospital's Suspected Child Abuse and Neglect (SCAN) Team was consulted. After excluding occult abusive injuries as well as testing for underlying medical conditions, the infant's bilateral subdural fluid collections were attributed to rupture of a pre-existing left middle cranial fossa arachnoid cyst with evidence of prior macrocephaly. CONCLUSION: In infants and toddlers, the identification of subdural fluid collections on neuroimaging warrants inclusion of AHT in the differential diagnosis. However, in infants with a history of congenital macrocephaly, and an otherwise negative AHT workup, an accidental mechanism for the formation of subdural collections should be considered, especially when co-occurring with an arachnoid cyst.

RESUMO

We report a rare presentation of xerophthalmia due to partial pancreatic exocrine insufficiency following Frey's surgery (pancreatic resection) in a 12-year-old girl. The child had undergone this surgery for chronic calcific pancreatitis 3 years before and presented with ocular irritation and decreased vision of 3 months duration. Ocular examination showed severe conjunctival and corneal xerosis. Her serum retinol levels and 25-hydroxyvitamin D were tested and were extremely low. The condition rapidly reversed following high-dose replacement therapy with vitamin A and D. This case highlights the importance of continuous enzyme replacement therapy as well as dietary modification and nutritional supplement therapy and monitoring of ocular symptoms in post-pancreatic surgery.

RESUMO

OBJECTIVE: Sudden unexpected death in epilepsy (SUDEP) is a major outcome of cardiac dysfunction in patients with epilepsy. In continuation of our previous work, the present study was envisaged to explore the key regulators responsible for cardiac damage associated with chronic seizures using whole transcriptome and proteome analysis in a rat model of temporal lobe epilepsy. METHODS: A standard lithium-pilocarpine protocol was used to induce recurrent seizures in rats. The isolated rat heart tissue was subjected to transcriptomic and proteomic analysis. An integrated approach of RNA-Seq, proteomics, and system biology analysis was used to identify key regulators involved in seizure-linked cardiac changes. The analyzed differential expression patterns and network interactions were supported by gene and protein expression studies. RESULTS: Altogether, 1157 differentially expressed genes and 1264 proteins were identified in the cardiac tissue of epileptic animals through RNA-Seq and liquid chromatography with tandem mass spectrometry-based proteomic analysis, respectively. The network analysis revealed seven critical genes-STAT3, Myc, Fos, Erbb2, Erbb3, Notch1, and Mapk8-that could play a role in seizure-mediated cardiac changes. The LC-MS/MS analysis supported the activation of the transforming growth factor ß (TGF-ß) pathway in the heart of epileptic animals. Furthermore, our gene and protein expression studies established a key role of STAT3, Erbb, and Mapk8 to develop cardiac changes linked with recurrent seizures. SIGNIFICANCE: The present multi-omics study identified STAT3, Mapk8, and Erbb as key regulators involved in seizure-associated cardiac changes. It provided a deeper understanding of molecular, cellular, and network-level operations of the identified regulators that lead to cardiac changes in epilepsy.

RESUMO

PURPOSE: To study the type of bacteria and their antibiotic susceptibility pattern from corneal scrapings of patients with infectious keratitis presenting with concurrent nasolacrimal duct obstruction. METHODS: A retrospective analysis was carried out of patients with microbial keratitis and co-existing nasolacrimal duct obstruction during a 5-year period (January 2012 to December 2016). Antibiotic susceptibility profile data was collected from the microbiology records. RESULTS: The study included 56 (M:F = 33:23; OD:OS = 34:22) eyes. The mean age of patients was 60.2 ± 12.3 years. Microscopic examination of corneal scrapings showed 52% of gram-positive (n = 29/55) and 2% of multiple (>1; n = 1/55) bacteria. Streptococcus pneumoniae (32%, n = 18/56), coagulase-negative Staphylococcus (25%, n = 14/56), and Staphylococcus aureus (11%, n = 6/56) were the most common bacteria. Streptococcus pneumoniae was found to be susceptible to ciprofloxacin (72.2%), ofloxacin (94.4%), gatifloxacin (61.1%), and moxifloxacin (83.3%). CONCLUSION: Corneal infection associated with nasolacrimal duct obstruction is commonly caused by gram-positive-bacteria. Irrigation of nasolacrimal duct should be mandatory test in microbial keratitis. The gram-positive bacteria isolated showed maximum susceptibility to vancomycin and cefazolin. Early treatment by surgery and appropriate medical management is recommended for its control.

RESUMO

BACKGROUNDS/AIMS: In the absence of national registry of laparoscopic cholecystectomy (LC) or its complications, it is impossible to determine incidence of bile duct injury (BDI) in India. We conducted an e-survey among practicing surgeons to determine prevalence and management patterns of BDI in India. Our hypothesis was that majority of surgeons would have experienced a BDI during LC despite large experience and that most surgeons who have a BDI tend to manage it themselves. METHODS: An 18-question e-survey of practicing laparoscopic surgeons in India was done. RESULTS: 278/727 (38%) surgeons responded. 240/278 (86%) respondents admitted to a BDI during LC and 179/230 (78%) affirmed to more than one BDI. A total of 728 BDIs were reported. 36/230 (15%) respondents experienced their first BDI even after >10 years of practice and 40% had their first BDI even after having performed >100 LCs. 161/201 (80%) of the respondents decided to manage the BDI themselves, including 56/99 (57%) non-biliary surgeons and 44/82 (54%) surgeons working in non-biliary center. 37/201 (18%) respondents admitted to having a mortality arising out of a BDI; the mortality rate of BDI was 37/728 (5%) in this survey. Only 13/201 (6%) respondents have experienced a medico-legal case related to a BDI during LC. CONCLUSIONS: Prevalence of BDI is high in India and occurs despite adequate experience and volume. Even inexperienced non-biliary surgeons working in non-biliary centers attempt to repair the BDI themselves. BDI is associated with significant mortality but litigation rates are fortunately low in India.

RESUMO

BACKGROUND: Lung cancer is characterized by uncontrolled cell growth of the lung tissues. It is the leading cause of cancer-related deaths worldwide. OBJECTIVES: The study aimed to determine the circulating CRP, TNF-α, IL-6 and IL-8 levels in lung cancer and healthy control and also established association between these biomarkers with the smoking status as well as the stages of the disease. METHODOLOGY: 51 lung cancer patients and 51 healthy controls were enrolled in this case-control study. The serum levels of CRP, TNF-α, IL-6 and IL-8 were measured in lung cancer patients and healthy control groups. RESULTS: The levels of serum CRP, TNF-α, IL-6 and IL-8 were significantly higher in lung cancer patients when compared with controls(P<0.0001). The levels of these biomarkers were also significantly higher in stage iii/iv as compared to stage i/ii(P<0.001). Significant difference in the levels of these biomarkers were also found in smoker and non-smoker lung cancer patients as compared to controls(P<0.001). CONCLUSION: CRP, TNF-α, IL-6 and IL-8 are the promising biomarkers in the identification of lung cancer patients. The study also supports the association of inflammatory markers to lung cancer risk. Hence these findings suggest the levels of these biomarkers could be a useful tool for guiding the diagnosis of lung cancer.
