Serum albumin is the strongest predictor of anti-tumor necrosis factor nonresponse in inflammatory bowel disease in resource-constrained regions lacking therapeutic drug monitoring

Background/Aims@#Evidence on predictors of primary nonresponse (PNR), and secondary loss of response (SLR) to anti-tumor necrosis factor (anti-TNF) agents in inflammatory bowel disease is scarce from Asia. We evaluated clinical/biochemical/molecular markers of PNR/SLR in ulcerative colitis (UC) and Crohn’s disease (CD). @*Methods@#Inflammatory bowel disease patients treated with anti-TNF agents (January 2005–October 2020) were ambispectively included. Data concerning clinical and biochemical predictors was retrieved from a prospectively maintained database. Immunohistochemistry for expression of oncostatin M (OSM), OSM receptor (OSM-R), and interleukin-7 receptor (IL-7R) were done on pre anti-TNF initiation mucosal biopsies. @*Results@#One-hundred eighty-six patients (118 CD, 68 UC: mean age, 34.1±13.7 years; median disease duration at anti-TNF initiation, 60 months; interquartile range, 28–100.5 months) were included. PNR was seen in 17% and 26.5% and SLR in 47% and 28% CD and UC patients, respectively. In CD, predictors of PNR were low albumin (P<0.001), postoperative recurrence (P=0.001) and high IL-7R expression (P<0.027) on univariate; and low albumin alone (hazard ratio [HR], 0.09; 95% confidence interval [CI], 0.03–0.28; P<0.001) on multivariate analysis respectively. Low albumin (HR, 0.31; 95% CI, 0.15–0.62; P=0.001) also predicted SLR. In UC, predictors of PNR were low albumin (P<0.001), and high C-reactive protein (P<0.001), OSM (P<0.04) and OSM-R (P=0.07) stromal expression on univariate; and low albumin alone (HR, 0.11; 95% CI, 0.03–0.39; P=0.001) on multivariate analysis respectively. @*Conclusions@#Low serum albumin at baseline significantly predicted PNR in UC and PNR/SLR in CD patients. Mucosal markers of PNR were high stromal OSM/OSM-R in UC and high IL-7R in CD patients.

An Uncommon Side Effect of a Commonly Used Antibiotic: Amoxicillin-Clavulanic Acid Induced Hepatitis / 가정의학회지

Amoxicillin-Clavulanic acid continues to be one of the most commonly used antibiotic combinations. Hepatic injury due to this antibiotic is rare. We report a case of amoxicillin-clavulanic acid induced hepatitis causing painless jaundice to bring to attention this rare side effect of this commonly used antibiotic. This is a case of a 62-year-old Caucasian female, who presented with acute onset severe painless jaundice, nausea, vomiting, and pruritus of less than 1-week duration. She had completed a course of amoxicillin-clavulanic acid 3 weeks prior to presentation. A careful history pointed to this simple diagnosis. It may be easily missed without an in-depth history and the patient may be subjected to unnecessary expensive tests. This case is reported to highlight cost conscious care by keeping in mind a rare side effect of the commonly used antibiotic.

Windsock deformity of interatrial septum.

Classical “Windsock deformity” is associated with ruptured aneurysmal sinus of Valsalva. The echocardiographic definition for Atrial septal aneurysm (ASA) in children based on dimensions is lacking. Rupture of an ASA, though uncommon, may lead to cardiac failure due to acute RV volume overload. An untreated ASA may be complicated with thrombus formation.

Quality of life and sociodemographic factors associated with poor quality of life in elderly women in Thiruvananthapuram, Kerala.

Background: India is going through a phase of demographic transition leading to population aging and feminization of aging resulting in increased proportion of elderly women than men. Problems faced by the elderly women are more critical than men due to family and social conditions prevailing in India. Objective: The study made an attempt to assess the quality of life (QOL) using the World Health Organization QOL (WHOQOL-BREF) scale and sociodemographic factors affecting QOL of elderly women residing in a community setting in South Kerala. Methods: A community-based, cross-sectional study to assess the QOL of elderly women using WHOQOL-BREF questionnaire. Data were collected from 160 elderly women. Results: 2.5% (95% confidence interval [CI]: 0.07-4.84) of the study participants were having "very good" QOL. 38.8% (95% CI: 31.2-46.4) had "good," 43.1% (95% CI: 35.4-50.8) had "poor," and 15.6% (95% CI: 9.98-21.22) had "very poor" QOL, respectively. QOL was least in the psychological domain followed by physical and health-related, social, and environmental domains. Logistic regression revealed age above 70 years (adjusted odds ratio [OR] - 11.3), nonpossession of property (adjusted OR - 8.99), neglecting attitude by family (adjusted OR - 6.9), and absence of visit by friends and relatives (adjusted OR - 9.9) as risk factors, whereas residing in the urban area as a protective factor (adjusted OR - 0.1) for poor QOL. Conclusion: It is possible to improve the QOL of elderly women by providing financial security, ensuring care, and by enhancing social relationships of elderly women.

Monitoring and decontamination of pesticide residues in okra (Abelmoschus esculentus Moench).

A monitoring study was carried out in okra for a period of six months to assess the level of pesticide residues of three different chemical groups ie organochlorines, organophosphates and synthetic pyrethroids. Okra samples showed residues of malathion and profenophos. To evaluate the effect of different decontaminating solutions in the removal of pesticide residues, okra var. Varsha Upahar was sprayed with a mixture of pesticides which were frequently detected in okra. Estimation of residues was done using Gas Chromatograph equipped with Electron Capture Detector. The results indicated that dipping in tamarind (2 %) solution for 15 minutes followed by washing in tap water was found to be more effective in reducing all pesticides tested when compared with other treatment solutions. This study helped to standardize simple cost effective strategies to eliminate harmful pesticides from okra which could be practiced by home makers.

From guidelines to ground reality: Maximizing the benefits of IDRV in the fourth year of its implementation.

The updated Thai Red Cross Intradermal (TRC-ID) regimen is the most effective strategy for India as it uses only 40% volume of vaccines in comparison with intramuscular (IM) when 0.5 ml vial is used and 20% when 1-ml vial is used; hence, the cost-effectiveness of intradermal (ID) regimen further increases when 1 ml vial is used. To improve the compliance of ID, postexposure prophylaxis (PEP) given free of cost is the ideal solution. For availability and avoiding administrative delays, universal ID delivery of PEP is the answer. ID is safe, effective, and well tolerated. Technique of ID can be learned easily. Universal ID with 1 ml is the ethical solution, which is easy to administer and monitor, economical, effective, and imparts early immunity (Five E's).

Vertebro-basilar dolichoectasia: a rare cause of stroke

We report a case of vertebro-basilar dolichoectasia in a 34 year old male patient who presented with sudden onset of headache, dizziness, diplopia and weakness of the left side of the body

Genetic characterization of dengue virus serotypes causing concurrent infection in an outbreak in Ernakulam, Kerala, South India.

Dengue fever, a mosquito-borne viral infection, causes significant morbidity and has become endemic in the Indian subcontinent. Virus strains currently circulating in many parts of the country are not well studied at the molecular level. In the present study, genetic characterization of virus strains from a dengue outbreak that occurred in and around a tertiary care hospital in Ernakulam, Kerala in the year 2008 has been reported. By reverse transcription polymerase chain reaction (RT-PCR), 37 out of 75 (49.3%) clinically suspected cases were positive for dengue viral RNA. Among these, 21 (56.8%) samples showed concurrent infection with multiple serotypes of the virus. Majority of the combined infections were caused by dengue serotype 2 and 3. Co-infections with type 1 and 2 in two patients, and type 1, 2 and 3 in one patient were also observed. The core-pre-Membrane (CprM) junction nucleotide sequencing and phylogenetic analysis revealed that the type 1 strains were related to the viral strains reported from Delhi-2001 and Gwalior-2002 dengue outbreaks, while the type 2 strains were related to the strains from Gwalior-2001 epidemic. Sequences of type 3 strains did not show clear relation to any of the previous Indian isolates, and in the phylogenetic analysis, they formed a distinct lineage within the Indian type 3 strains. This study indicates hyperendemicity of dengue in the region with the presence of multiple serotypes and high rates of co-infection, and local genomic evolution of the viral strains involved in this outbreak.

Tricuspid valve excision using off-pump inflow occlusion technique: Role of intra-operative trans-esophageal echocardiography.

A pacing system infection may lead to infective endocarditis and systemic sepsis. Tricuspid valve surgery may be required if the valve is severely damaged in the process of endocarditis. Although, cardiopulmonary bypass is the safe choice for performing right-heart procedures, it may carry risk of inducing systemic inflammatory response and multi-organ dysfunction. Some studies have advocated TV surgery without institution of CPB. We report tricuspid valve excision using the off-pump inflow occlusion technique in a 68-year-old man. We also describe role of intra-operative TEE as a monitoring tool at different stages of the surgical procedure. .

Role of intraoperative echocardiography in surgical correction of the superior sinus venosus atrial septal defect.

Superior type of sinus venosus atrial septal defect (SVASD) is invariably associated with the unroofing of right upper pulmonary vein (RUPV). Warden procedure and pericardial patch repair with rerouting of the RUPV are commonly performed operations for the superior SVASD. Both operations involve the risk of obstruction to the flow of superior vena cava or rerouted pulmonary vein in the postoperative period. The sinus venosus defects are well visualized on the transesophageal echocardiography (TEE) because of the proximity of the TEE probe to these structures. We are reporting two cases operated for the superior SVASD with unroofed RUPV, highlighting the intraoperative echocardiographic features before and after the surgery.

Small cell carcinoma occurring in a case of ulcerative colitis.

A 61-year-old man, with an 8-year history of ulcerative colitis, presented with bleeding per rectum for 4 weeks' duration. Colonoscopy revealed polypoidal neoplasm at the rectosigmoid junction. Histopathology depicted small cell carcinoma. On immunohistochemical staining, chromogranin A and synaptophysin were positive. The tumour was diagnosed as undifferentiated small cell carcinoma, which is unusual since generally it is the adenocarcinoma that occurs on a background of ulcerative colitis and there are only three previous reports of small cell carcinoma occurring in UC.

Neuroleptospirosis - revisited: experience from a tertiary care neurological centre from south India.

BACKGROUND & OBJECTIVES: Leptospirosis is a zoonotic disease commonly reported from south India. Neurological manifestations seen in about 10-15 per cent of cases, are protean and remain unrecognized and diverse. We evaluated the pattern of nervous system involvement in leptospirosis, among patients presenting to the emergency services of a tertiary care neurological centre in south India, and also analysed the outcome and prognostic indicators. METHODS: The diagnosis of neuroleptospirosis was based on clinical and laboratory evidence of hepatorenal syndrome, and serum or CSF positivity for antileptospira antibody by a macroscopic agglutination test (MAT) and by ELISA in a limited number of samples. RESULTS: A total of 31 patients (M:F 27:4, age range 6-68 yr, mean 36.4 +/- 14.3 yr) were treated during the five year period. Acute fever with chills and rigors, headache and vomiting were the presenting manifestations; 25 patients (81%) had altered sensorium for a period ranging from 1- 8 days, four (12.9%) being deeply comatose. Eleven (35.5%) had acute symptomatic seizures at the time of presentation. Conjunctival congestion with or without haemorrhage was seen in 12 patients (38.7%), icterus in 14 (45%) and mild hepatosplenomegaly in 11 (35.5%). Early papilloedema was observed in three. Only three patients had localizing deficits. CT scan was normal in 18 of 27 (67%), while 7 (26%) had diffuse cerebral oedema. CSF pleocytosis with lymphocytic predominance (mean 50 cells/microl) and elevated protein levels (mean 115.5 +/- 67.5 mg %) were noted. Leptospira antibody was detected in serum of all, and 5 of 22 in CSF samples. Eight patients (26%) succumbed. Deep altered sensorium at presentation and raised CSF protein were two poor prognostic indicators. Pathological study of brain in five cases revealed encephalitic features and in addition immune mediated acute disseminated encephalomyelitis (ADEM) like pathology in two cases. INTERPRETATION & CONCLUSION: Neuroleptospirosis should be considered in the differential diagnosis of neuroinfections associated with hepatorenal dysfunction, in endemic areas. Leptospira antibody can be detected in CSF also in some cases. Deep altered sensorium at presentation indicates poor prognosis.

Malignant melanoma metastatic to bone marrow.

Bone marrow aspiration and biopsy is a useful means of detecting systemic involvement in patients with non haematological malignancy. Metastases of malignant melanoma may be detected in the bone marrow in a small percentage of patients. Two cases of malignant melanoma, with metastasis to marrow at the time of presentation, are described. In one case, bone marrow was the first site where the malignancy was identified. Subsequent investigations revealed an anal melanoma. In the second case, the patient had widespread dissemination from a tonsillar melanoma to many organs of the body, including bone marrow.

Cold haemagglutinin disease in systemic lupus erythematosus

A 34-year-old lady presenting with features of cold agglutinin disease during the course of systemic lupus erythematosus is described. Cold antibody titer was very high (1 in 4096) with specificity for 'I' antigen. Even though she had poor prognostic factors like high titer of cold antibodies with low thermal amplitude, she responded well to prednisolone.

Immunoblastic lymphadenopathy, a case report
