    The contribution of all key healthcare professionals is vital to promote an efficient adverse drug reaction (ADR) reporting system. In this context, nurses are important as they are in a better position to observe a patient's response regarding the drug therapy and to report an ADR. The aim of the study was to explore the perspectives of nurses about ADR reporting system in Lahore, Pakistan. A total of 21 nurses were interviewed. The thematic content analysis of the qualitative interviews yielded six major themes and eight subthemes. Major themes included: (1) Knowledge about the concept of the medication safety & the ADR; (2) Knowledge regarding pharmacovigilance activities; (3) Willingness to report; (4) Practices related to the ADR reporting; (5) Barriers to the ADR reporting; (6) Facilitators to the ADR reporting. The majority of the nurses were aware of medicine safety and ADRs, but in many cases, they were unable to report these ADRs. The study pointed out considerable concerns regarding the knowledge and practices of nurses about pharmacovigilance activities in their workplace, mainly due to increased workload, due to the absence of a reporting system and legal liability. The main challenges turned out to be the lack of knowledge and training, as well as the implementation of guidelines. Based on the findings, it is suggested that outcome of this study can serve as a guide to design policies that support ADR reporting by nurses in Pakistan.

    J Oleo Sci, 2020 Jul 02;69(7):671-676.
    PMID: 32522941 DOI: 10.5650/jos.ess19253
    The study was designed to evaluate the nutritive value, thermal stability and consumer acceptance of cupcakes baked with red palm olein compared to palm olein. Thermal stability was evaluated for acidity, peroxide, p-anisidine and total oxidation value (cumulative between peroxide and p-anisidine values), as well as fatty acid composition. The concentrations of phytonutrients including tocopherols and tocotrienols, alpha- and beta-carotene after baking were also determined. Acceptance of the cupcakes was assessed using a structured hedonic scale of five points by 29 panelists. As compared to initial test oil (red palm olein), acidity (red palm olein, 0.07±0.01% vs cupcakes containing red palm olein, 0.09±0.01%; P=0.0232), peroxide value (red palm olein, 0.33±0.05 meq O2 kg-1 vs cupcakes containing red palm olein 0.73±0.06 meq O2 kg-1; P=0.0011) and total oxidation value (red palm olein, 2.24±0.13 unit vs cupcakes containing red palm olein, 3.09±0.17 unit; P=0.0012) were found to be higher in cupcakes containing red palm olein, which is within the acceptable rancidity range (peroxide value < 7.5 meq O2 kg-1) for snack food category. No changes were found on oxidative parameters (acidity, peroxide, p-anisidine values and total oxidation value) in cupcakes containing palm olein. Cupcakes made with red palm olein retained nearly 100% of alpha- and beta-carotenes upon baking. Tocopherol homologues were stable in both comparisons, with 95% retention as compared to tocotrienol homologues (~85%). Cupcakes made from red palm olein received higher score (mean=3.29) in sensory evaluation as compared to cupcakes containing palm olein (mean=3.07). The study, therefore, encourages the inclusion of red palm olein in the formulation of bakery products.

    PMID: 32528674 DOI: 10.1016/j.amsu.2020.05.018
    Background: Gastrooesophageal reflux disease (GERD) is a spectrum of symptoms arising from the laxity of the cardio-oesophageal junction. Anti-reflux surgery is reserved for patients with refractory GERD. Anterior partial fundoplication (Dor) is a regularly performed anti-reflux surgery in Malaysia. We intend to determine the improvement in disease-specific quality of life in our patients after surgery.

    Methods: A multicentre cross-sectional study was conducted to assess patients' improvement in disease-specific quality of life after Dor fundoplication. Ethics approval was obtained from our institutional review board. Patients between the ages of 18 and 65 years who underwent Dor fundoplication within the past five years were assessed using the GERD HRQL as well as the VISICK score via telephone interview. We excluded cases of revision surgery.

    Results: Out of 129 patients screened, 55 patients were included. We found a significant improvement in patients' GERD HRQL score with the pre-operative mean score of 28.3 ± 9.39 and 6.55 ± 8.52 post-operatively, p

    Influenza-associated mortality has not been quantified in the Philippines. Here, we constructed multiple negative binomial regression models to estimate the overall and age-specific excess mortality rates (EMRs) associated with influenza in the Philippines from 2006 to 2015. The regression analyses used all-cause mortality as the dependent variable and meteorological controls, time, influenza A and B positivity rates (lagged for up to two time periods), and annual and semiannual cyclical seasonality controls as independent variables. The regression models closely matched observed all-cause mortality. Influenza was estimated to account for a mean of 5,347 excess deaths per year (1.1% of annual all-cause deaths) in the Philippines, most of which (67.1%) occurred in adults aged ≥60 years. Influenza A accounted for 85.7% of all estimated excess influenza deaths. The annual estimated influenza-attributable EMR was 5.09 (95% CI: 2.20-5.09) per 100,000 individuals. The EMR was highest for individuals aged ≥60 years (44.63 [95% CI: 4.51-44.69] per 100,000), second highest for children aged less than 5 years (2.14 [95% CI: 0.44-2.19] per 100,000), and lowest for individuals aged 10 to 19 years (0.48 [95% CI: 0.10-0.50] per 100,000). Estimated numbers of excess influenza-associated deaths were considerably higher than the numbers of influenza deaths registered nationally. Our results suggest that influenza causes considerable mortality in the Philippines-to an extent far greater than observed from national statistics-especially among older adults and young children.

    Rotaviruses are the most common cause of viral gastroenteritis with the highest mortality and morbidity rates in children aged 0-5 years. The aim of this study was to determine the frequency of rotavirus infection in patients whose stool samples were sent to microbiology laboratory to investigate the etiology of diarrhea, to investigate the rotavirus genotypes that are common in our region and G10, G12 genotypes that have recently become common in the world. Fecal samples of 476 patients aged between 0-92 years who applied between November 2016 and February 2018 were studied via immunochromatographic rapid test and enzyme-linked immunosorbent assay (ELISA) methods. ELISA positive samples were studied by nested reverse transcriptase chain reaction (RT-PCR) and genotyped by agarose gel electrophoresis. Rotavirus was found positive in 18.3% and 17% of stool samples by immunochromatographic test and ELISA, respectively. All ELISA positive samples were also detected as positive by RT-PCR. 18.5% of female patients and 15.7% of male patients were found to be positive and rotavirus positivity was not statistically significant between genders. The frequency of rotavirus in different age groups was 23.5% (6-12 years), 17.3% (13-24 months) and 16% (25-36 months). It was determined that rotavirus cases were most common in the spring. G1, G2, G3, G4, G9, G10, and G12 were detected in 37%, 7.4%, 16.1%, 6.2%, 9.9%, 2.5%, 26% of the samples, respectively. G12 was the most common genotype after G1. The most common G and P genotype combination was G1P[8] (17.2%). This was followed by G12P[8] (11.11%) and G3P[8] (11.11%). P[8] (53%) was found to be the dominant P genotype. In this study, it was observed that rotavirus, which is the cause of childhood diarrhea, can also be encountered in advanced ages and even new genotypes that infect humans worldwide may also be the causative agents. Therefore, we concluded that it is important to investigate new genotypes such as G10 and G12 in molecular epidemiological studies.

    Toxoplasma gondii is an obligate intracellular protozoan parasite that causes toxoplasmosis in humans. To date, little is known about T. gondii infection among the indigenous community, particularly in East Malaysia. This study was conducted to determine the status of T. gondii infection and to investigate associated risk factors among the indigenous community of Sarawak, East Malaysia. The sociodemographic data was obtained using a pretested questionnaire. A serological test was done to detect the presence of specific IgM and IgG antibodies against T. gondii in serum samples. A nested polymerase chain reaction (PCR) was used to determine acute infection among seropositive individuals. The overall seroprevalence of T. gondii infection was 50% (95% CI = 43.3 - 56.7). From this subset, 40.1%, 5.7%, and 4.2% were positive for anti-T. Gondii IgG antibodies, IgM, and both IgG and IgM, respectively. Four seropositive samples were amplified through PCR. None of the pregnant women tested positive for T. gondii infection based on the serological and PCR assays. A significant association was found between age, low monthly household income, unemployment, usage of untreated water and close contact with T. gondii seropositive cats. These results provide basic information on T. gondii infection and may be useful for policymakers to initiate prevention and control programs, especially amongst pregnant women and women of childbearing age in the indigenous community.

    Soil-transmitted helminth (STH) could possibly cause mild to severe health effects such as diarrhea, weakness, intestinal blood loss, and impaired cognitive development and growth. In Malaysia, previous studies depicted a high prevalence rate of STH was due to poor hygiene practice and low efficacies of anthelminthic drugs. This study was conducted to investigate hand hygiene practice and WASH criteria's (Water, sanitation and hygiene) related to STH infection among two indigenous tribes in Peninsular Malaysia. A cross-sectional study was carried out to study the relationship among STH infection compared to water quality, sanitation, and hygiene conditions. A total of 190 individuals from two indigenous villages participated in the study, with ages ranging from 5 to 60 years old. In addition, Pearson's Chisquare (X2) test was utilized to test the relationship among STH with demographic socioeconomic and behavioral factors. The confidence interval (CI) of 95% is used to estimate the precision of the odds ratio (OR). Multivariate logistic regression models were also used to identify the risk factors associated with STH infections. The overall findings indicated a prevalence rate of 72% for STH, and distributed mainly among children aged < 12 years. Furthermore, multivariate analyses using logistic regression revealed chronic health problems, incorrect hand washing, and walking bare footed were associated with STH infection. Overall results indicated high prevalence of STH among the indigenous villagers, which aligns with the published literature and proves to be a problem need to be addressed as neglected disease. Interestingly, there was a significant relationship between the presences of chronic diseases and STH infection, which prompted other questions the awareness needs to be educated and the simple and low-cost intervention on the proper way of hand washing may help to reduce STH infection in these indigenous communities.

    An outbreak of dengue in Kudat, northern Sabah in 2016-2017 provided an opportunity to investigate the circulating serotypes of dengue viruses of cases at Hospital Kudat. Between September 2016 and December 2017, a total of 156 dengue positive sera (tested positive by either NS1 antigen, or IgM and IgG antibody rapid test) were collected from dengue patients who had acute fever and showed signs and symptoms suggestive of dengue. RNA was extracted from the sera using QIAamp RNA Blood Mini Kit, and molecular amplification was performed using one-step RT-PCR kit, followed by nested PCR using HotStart Taq master mix kit with the primers of the dengue C-prM gene. There were 81 (52%) male and 75 (48%) female cases. The age group with the highest number of cases was the 10-19 years old, while the youngest infected was 8 months old and the oldest was 83 years old. RT-PCR results showed 88 sera dengue positive, 48 infected with a single serotype while another 40 with multiple serotypes. All four DENV serotypes were co-circulating during the outbreak period and DENV-1 was predominant. Molecular analysis also indicated 69.2%, 50.0%, 51.9% and 48.9% respectively of the NS1, IgM, IgG and IgM and IgG positive sera were RT-PCR positive for dengue. High number of cases were seen in December 2016, February and May 2017. The dengue outbreak might be related to switching of predominant serotype from DENV 4 to DENV 1.

    A 24-year-old man born in Guizhou province was diagnosed with obstructive jaundice and bile duct stones in 2013. Four living trematodes were found during laparotomy and cholecystectomy. Based on the morphology and molecular genetics analysis of internal transcribed spacer and pcox1 genes of the flatworm specimens, the trematodes from the patient were confirmed to be Fasciola hepatica. This report provided the clinical and molecular diagnosis information on human fascioliasis, which is an emerging sanitary problem still ignored in China. Human fascioliasis constantly occurs due to climatic changes and frequency of human travel. Therefore, it deserves more attention from physicians working in both developing and developed countries.

    The hepatitis C virus (HCV) is a blood-borne pathogen that causes acute or chronic infection of the liver, sometimes leading to serious liver damage and fatality. The objective of this study was to evaluate HCV prevalence in patients attending the Regional Training and Research Hospital for Medical Examination and Surgery in Samsun Province of Turkey between 2014 and 2017. Blood specimens taken from 152 596 patients were screened for HCV infection by using the anti-HCV assay. Seropositive samples were subjected to polymerase chain reaction (PCR) testing in order to determine whether the HCV infection was active. Genotyping was then performed. Overall, HCV seropositivity and active HCV infection were 2.76% and 2.05%, respectively. Foreign nationals accounted for 5.61% of the seropositive samples and 1.37% of active HCV infective samples. We further report that 2017 was the year with the highest seroprevalence which was 3.64%. HCV genotype 1 was the most common genotype detected in residents of Samsun Province at 89.86%, followed by Genotype 3 at 4.54%. This study provides important information on the levels of HCV infection in the Samsun region of Turkey. The data indicate that there was a rising trend of HCV infection between 2014 and 2017.

    Toxoplasmosis is a zoonotic disease caused by Toxoplasma gondii that is prevalent in humans and animals. This study was aimed to determine the seroprevalence of T. gondii infection among hemato-oncology patients and its association with sociodemographic and behavioural characteristics. This cross-sectional study was conducted at the Hospital Universiti Sains Malaysia (USM) involving 56 blood samples from hemato-oncology patients. Anti-T. gondii IgG and IgM antibodies and IgG avidity were determined using enzyme-linked immunosorbent assays (ELISA). The association of T. gondii exposure, sociodemographic, and behavioural characteristics were assessed by a questionnaire and face-to-face interviews. Twenty-eight (50%) patients were seropositive for T. gondii antibodies, where 27 (48.21%) patients were IgG+/IgM- and one patient (1.79%) was IgG+/IgM+ with high avidity index, indicating infection of more than 20 weeks. A univariate analysis showed that age, gender, ethnicity, marital status, educational level, employment status, stem cell transplant, blood transfusion, close contact with cats, water supply, and consumption of undercooked meat were not significantly associated with Toxoplasma seropositivity (p < 0.05). Our study has demonstrated, for the first time, the serological evidence of T. gondii exposure among hemato-oncology patients in Hospital USM. Our findings indicated that latent toxoplasmosis was relatively prevalence among our patients. Therefore, serological screening tests should be considered for immunocompromised patients as well as the implementation of health education programmes to encourage a healthy lifestyle and the consumption of healthy food among them.

    PMID: 23317228
    BACKGROUND: The aim of the study was to determine the prevalence of shisha smoking and associated factors among medical students in Malaysia.

    MATERIALS AND METHODS: A cross-sectional study was conducted at the Management and Science University from December 2011 until March 2012. The questionnaire consisted of five sections including socio-demographic, social environment, knowledge about shisha, psychosocial factors, and personal shisha smoking behavior. Obtained data were analyzed using Statistical Package for the Social Sciences (SPSS 13). T-test was used to determine the relationships between shisha smoking and socio-demographic characteristic.

    RESULTS: A total number of 300 medical students participated in this study. Mean age was 22.5±2.5 years. The majority were female, Malay, single, from urban areas (67%, 54%, 97%, 73%; respectively). The prevalence of shisha smoking among medical students was found to be 20%. The study revealed that many students believed that shisha does not contains nicotine, carbon monoxide, does not lead to lung cancer, dental problems and does not lead to cardiovascular diseases (25%, 20.7%, 22.3%, 29%, 26.7%; respectively). Age and sex were found to be significantly associated with smoking shisha status among medical students (p=0.029, p<0.001; respectively). Furthermore, having parents, siblings and friends smokers of shisha were found to be significantly associated with shisha smoking status (p<0.001, p<0.001, p<0.001; respectively). Furthermore, family problems, problems with friends, financial problems and university life were found to significantly associated with shisha smoking status among medical students (p<0.001, p=0.002, p<0.001, p=0.002; respectively).

    CONCLUSIONS: There is a high prevalence of shisha smoking and a poor knowledge about its impact on health among medical students. More attention is needed to focus on medical education in this regard. The policies that are currently employed in order to reduce the cigarettes smoking should be applied to shisha smoking and shisha products.

    Pneumocystis pneumonia (PCP) and pulmonary tuberculosis infection (PTB) are important opportunistic infections in HIV-infected patients. The diagnosis remains challenging since Pneumocystis jirovecii cannot be cultured, and expectorated-sputum is frequently difficult to obtain. The monoclonal-antibody detection for P. jirovecii from induced sputum is promising in diagnosing PCP. This study determined the percentage of PCP in HIV-infected patients with pulmonary infiltrates at three government hospitals in Jakarta. The concurrent infection of PTB was carefully documented as well. This cross-sectional study was carried out by documenting the clinical symptoms, laboratory findings, chest X-ray, while clinical outcomes were evaluated during hospitalization. The sputum induction was conducted for P. jirovecii with monoclonal antibody detection at the laboratory of Parasitology Department, Faculty of Medicine Universitas Indonesia, as well as Ziehl-Nielsen staining for PTB. The results indicated that of 55 HIV-infected patients with pulmonary infiltrates, the positive monoclonal antibody for P. jirovecii was detected in eight patients (14.6%). Weight loss, fever, shortness of breath, and crackles were found in all PCP patients; while dry cough in five patients. Moreover, PTB cases with positive acid-fast bacilli (AFB) was detected in five patients (9.1%), the PTB cases with negative AFB was 43.6% (24 out of 55 patients), and the rest 26 patients (47.3%) were not proven to have PTB. The concurrent infections of PCP and PTB were documented in three out of five positive AFB patients. The clinical outcome of eight PCP patients showed improvement in five patients, but the other three patients died. Laboratory findings play an important role in the diagnosis of PCP and PTB, along with clinical characteristics and radiological features. Low CD4+ cell count was considered a possible risk factor for PCP and poor clinical outcomes.

    Opisthorchiasis caused by Opisthorchis viverrini infection is a major public health concern in Thailand. Despite many decades of national campaigns in place to reduce and control opisthorchiasis in Thailand, the infections remain to exist particularly in the northern and northeastern parts of the country. This study aimed to evaluate the current prevalence of O. viverrini infection in rural communities in northeast Thailand. A cross-sectional survey was conducted between February and October 2018 in three districts (Na Kae, That Phanom and Wang Yang) in Nakhon Phanom Province, Thailand. Demographic data were collected using a standardised questionnaire. Stool samples were collected and processed using the Kato-Katz technique to determine the presence of O. viverrini and other intestinal parasites. In total, 564 individuals were enrolled. The overall intestinal helminth infections were 15.2% (95% CI: 12.4-18.5). Species distribution included a majority of O. viverrini mono-infections (12.9%), followed by Strongyloides stercoralis (1.4%) and Taenia spp. (0.4%). The prevalence of O. viverrini was significantly higher in Wang Yang district (P = 0.022), in males (P = 0.004) and those previously positive with helminth infections (P<0.001) and received treatment of anti-helminths (P<0.001), than in their counterparts. Multivariate regression analysis revealed that being male (adjusted odds ratio [aOR] 1.77, P = 0.035) and those who previously tested positive for helminth infections (aOR 8.69, P<0.001) were significantly associated with a higher odd of O. viverrini infections, but lower in those who had previous stool examination (aOR 0.22, P = 0.001). This study demonstrated that the updated prevalence of O. viverrini infection is still high in rural communities in northeast Thailand. The data of this study will be useful to guide and improve strategies for future O. viverrini and other helminths prevention and control in this region.

    Toxoplasma gondii is a protozoan parasite that can infect all mammals, serving as intermediate hosts. The cause of congenital toxoplasmosis is transplacental transmission of the parasite to the foetus, resulting in wide range of manifestations from mild chorioretinitis to miscarriage. Its frequency can be reduced by early screening of pregnant women which is based mainly on tests for anti-Toxoplasma antibodies. We collected serum samples of 594 pregnant women (subjects) after taking their consent over a period of two years (2016-2018) and analyzed them for anti-Toxoplasma IgG by ELISA. The positive samples were then analyzed for IgG avidity test which could differentiate between recent and past infections. The seroprevalence was also correlated with the age of the subjects and their contact with cats. 162 subjects were found positive out of which only three showed a recent infection. After following up until delivery, one of them delivered a baby who had jaundice and was diagnosed with anti-Toxoplasma IgM at birth. The foetus of the second subject died in-utero, while the third woman delivered a normal baby after being given spiramycin when diagnosed with toxoplasmosis in the first trimester. It was found that most of the positive subjects had frequent contact with cats. Invasion of the parasite during third trimester resulted in death in-utero and jaundice. Most common cause of pregnancy wastage during our study was spontaneous abortions while pregnancy loss due to congenital anomalies was rare.

    PURPOSE: To evaluate the influence of iterative reconstruction (IR) levels on Computed Tomography (CT) image quality and to establish Figure of Merit (FOM) value for CT Pulmonary Angiography (CTPA) examinations.

    METHODS: Images of 31 adult patients who underwent CTPA examinations in our institution from March to April 2019 were retrospectively collected. Other data, such as scanning parameters, radiation dose and body habitus information from the subjects were also recorded. Six different levels of IR were applied to the volume data of the subjects. Five circles of the region of interest (ROI) were drawn in five different arteries namely, pulmonary trunk, right pulmonary artery, left pulmonary artery, ascending aorta and descending aorta. The mean Signal-to-noise ratio (SNR) was obtained, and the FOM was calculated in a fraction of the SNR2 divided by volume-weighted CT dose index (CTDIvol) and SNR2 divided by the size-specific dose estimates (SSDE).

    RESULTS: Overall, we observed that the mean value of CTDIvol and SSDE were 13.79±7.72 mGy and 17.25±8.92 mGy, respectively. Notably, SNR values significantly increase with increase of the IR level (p

    BACKGROUND: The graviceptive otolith function can be measured using subjective visual horizontal (SVH) testing. Nevertheless, more research efforts are required to understand the essential variables affecting SVH.

    OBJECTIVE: The aim of the present study was to determine the effects of type of visual image and gender on subjective visual horizontal (SVH) perception among healthy adults.

    MATERIALS AND METHODS: In this comparative study, 50 healthy young adults were enrolled. While in an upright body position, they were required to report their perception of horizontality for two types of visual images (solid line and arrow pattern) using a computerized SVH device.

    RESULTS: The arrow pattern produced significantly bigger SVH angles than the solid line (p < .001). In contrast, no significant influence of gender was found on SVH results (p = .743), Based on the statistical outcomes, the preliminary normative data for SVH were established.

    CONCLUSIONS AND SIGNIFICANCE: The arrow pattern (a more complex visual image) produced bigger SVH deviations than the simple solid line image. In contrast, the horizontality perception does not appear to be affected by gender. The preliminary normative SVH data gathered from the present study can be beneficial for clinical and future research applications.

    Avascular necrosis of bone (AVN) is increasingly being recognized as a complication of SLE and causes significant disability due to pain and mobility limitations. We studied the prevalence and factors associated with avascular necrosis (AVN) in a multiethnic SLE cohort. SLE patients who visited the outpatient clinic from October 2017 to April 2019 were considered eligible. Their medical records were reviewed to identify patients who developed symptomatic AVN, as confirmed by either magnetic resonance imaging or plain radiography. Subsequently, their SLE disease characteristics and treatment were compared with the characteristics of patients who did not have AVN. Multivariable logistic regression analyses were performed to determine the independent factors associated with AVN among the multiethnic SLE cohort. A total of 390 patients were recruited, and the majority of them were females (92.6%); the patients were predominantly of Malay ethnicity (59.5%), followed by Chinese (35.9%) and Indian (4.6%). The prevalence of symptomatic AVN was 14.1%, and the mean age of AVN diagnosis was 37.6 ± 14.4 years. Both univariate and multivariable logistic regression analyses revealed that a longer disease duration, high LDL-C (low density lipoprotein cholesterol), positive anti-cardiolipin (aCL) IgG and anti-dsDNA results, a history of an oral prednisolone dose of more than 30 mg daily for at least 4 weeks and osteoporotic fractures were significantly associated with AVN. On the other hand, hydroxychloroquin (HCQ), mycophenolate mofetil (MMF) and bisphosphonate use were associated with a lower risk of AVN. No associations with ethnicity were found. In conclusion, several modifiable risk factors were found to be associated with AVN, and these factors may be used to identify patients who are at high risk of developing such complications. The potential protective effects of HCQ, MMF and bisphosphonates warrant additional studies.

    BACKGROUND: Tuberculosis (TB) and human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) infections are leading causes of morbidity and mortality worldwide. People living with HIV/AIDS (PLWHA) are highly susceptible to TB infection and progression to active TB disease. This study aims to determine the proportion and risk factors of TB among PLWHA in Jazan Region, southwestern Saudi Arabia.

    METHODS: A cross-sectional study was conducted among HIV-infected individuals attending the main referral hospital in Jazan Region during the period 2017-2019. The participants' TB status, CD4+ lymphocyte count, and viral load were assessed. In addition, their demographic and clinical information was collected using a structured questionnaire.

    RESULTS: A total of 316 HIV-positive individuals aged between 13 and 81 years (75% male and 25% female) were enrolled in this study. Of them, 30 (9.5%; 95% confidence interval [CI]: 5.2, 10.6%) were diagnosed with TB: 46.7% (14/30) had pulmonary TB and 53.3% (16/30) had extrapulmonary TB. The highest proportion of TB-positive PLWHA was found among participants aged 18-30 years (11.6%) and among non-Saudis (14.0%) when compared to other age groups and Saudi participants (7.4%). Multivariate analysis showed that male gender (adjusted odds ratio [AOR] = 4.79; 95% CI = 1.22, 18.74), past medical history (PMH) of TB (AOR = 29.67; 95% CI = 5.31, 164.32), PMH of other RTIs (AOR = 5.86; 95 % CI = 2.14, 16.06), CD4+ lymphocyte count of <200 cells/mm³ (AOR = 4.33; 95% CI = 1.65, 11.36), and viral load of ≥1 × 103 copies/mL (AOR = 5.46; 95% CI = 2.02, 14.77) were the significant risk factors of TB among the studied PLWHA.

    CONCLUSION: The prevalence of TB/HIV co-infection among the studied population was 9.5%. Therefore, all PLWHA should be screened for TB at every visit to a health facility. The findings highlight that integration of health services for both TB and HIV/AIDS in Saudi Arabia is recommended.
