RESUMEN
Objectives: This study aimed to determine the epidemiology, clinical features, and complications of extensively drug-resistant Salmonella typhi (XDR S. typhi) infection in adults. Method: This cross-sectional study enrolled adults with culture-proven XDR S. typhi admitted to Hayatabad Medical Complex, Peshawar from 1st March to 10th September 2022. Their demographic characteristics, clinical features, treatment, and complications were recorded. Results: Out of 84 patients, 68 (80.9%) were male. The mean age of enrolled patients was 25.2 ± 11.3 years. The mean duration of fever at the time of admission was 13.6 ± 8.2 days, respectively. The most common symptom was loose stools (n=25, 29.8%). Most of the patients (n=69, 82.1%) had received empirical treatment before hospitalization. The majority of the patients (n=42, 50%) received meropenem and a combination of meropenem and azithromycin (n=35, 41.7%) during the study. The time to defervescence for both regimens was similar. Five patients (6%) developed complications of enteric fever. There was no mortality among the participants. Conclusions: Diarrhea was the most common associated clinical feature in XDR typhoid fever. Most of the patients received meropenem alone or in combination with azithromycin with a comparable time to defervescence. The majority of the patients recovered uneventfully and there was no mortality among the study participants.
RESUMEN
Multi-drug resistant strains of Salmonella typhi (S. typhi) has remained endemic in developing countries for the last two decades. With irrational use of antibiotics, an extensively drug-resistant (XDR) strain of S. typhi, sensitive only to Carbapenems and Azithromycin, has evolved which was first reported in Sindh, Pakistan, in 2018. Most of the cases of XDR S. typhi infection treated with antibiotics improve without any complications. Failure to respond to appropriate antibiotics should raise the suspicion of visceral abscesses. Splenic abscess is a rare complication of S. typhi infection. A patient with splenic abscess due to XDR S. typhi has been reported who responded to prolonged antibiotic treatment. We report the case of a young boy from Peshawar with multiple splenic abscesses due to XDR S. typhi which did not respond to percutaneous aspiration and culture-guided antibiotics for two weeks. Eventually, he had to undergo splenectomy. He has remained afebrile since then.

Objective To determine the clinical and biochemical predictors of mortality in patients with dengue fever. Methods This was an analytical, cross-sectional study conducted at Hayatabad Medical Complex, Peshawar, Pakistan. The study participants were patients admitted to the hospital for the management of dengue fever. Clinical parameters (age, gender, duration of hospital stay, and the presence of complications) and biochemical parameters [white blood cells count (WBC), platelet count, serum c-reactive protein (CRP) level, serum alanine aminotransferase (ALT) level, and serum creatinine] were recorded. These parameters were compared between the survivors and non-survivors of dengue fever. Results Out of 115 patients, the majority (n=82, 71.3%) were up to 45 years and the mean age was 38.40 ± 18.1 years. Most of the patients (n=105, 91.3%) survived. On univariate logistic regression analysis, age more than 45 years [odds ratio (OR) 0.141, 95% confidence interval (CI) 0.034 - 0.585, p = 0.007), leukocytosis (> 11,000/mcL) (OR 0.187, 95% CI 0.049 - 0.719, p = 0.015), and acute kidney injury (creatinine > 1.5 mg/dL) (OR 0.124, 95% CI 0.029 - 0.531, p = 0.005)] at the time of admission reduced the likelihood to survive. Leukocytosis and acute kidney injury remained significant independent predictors of mortality on multivariate logistic regression analysis. [(OR 0.201, 95% CI 0.042 - 0.960, p = 0.044) and (OR 0.148, 95% CI 0.026 - 0.857, p = 0.033) for survival, respectively]. Gender, duration of inpatient stay, thrombocytopenia (platelets < 30,000/mcL), and acute liver injury (ALT > 200 IU/L) were not associated with mortality from dengue fever. Conclusion Age over 45 years, leukocytosis, and acute kidney injury at presentation increased the likelihood of mortality from dengue fever in this study. Gender, duration of hospital stay, thrombocytopenia, and acute liver injury did not affect the odds of mortality.
RESUMEN
Background: This study aims to compare lymphocyte count, C-reactive protein (CRP), ferritin, Lactate Dehydrogenase (LDH) and D-dimer among survivors and non-survivors of severe COVID-19. Methods: This retrospective cross-sectional analytical study included 69 patients for whom a record of the biomarkers and survival status was available. Baseline and peak values were selected for serum CRP, ferritin, LDH and D-Dimer. Baseline and trough lymphocyte counts were selected. Data were analyzed using SPSS version 21. Mean and standard deviation were used to compare the biomarkers with paired t-test. p-value <0.05 was taken as significant. Results: The mean age of the study population was 55.5±9.1 years and 50 (72.5%) were male. Among survivors, the increase in CRP level was not significant (from 15.80±9.8 mg/dl to 17.87±8.4 mg/dl, p=0.45) while it was significant in non-survivors (from 16.68±10.90 mg/dl to 20.77±12.69 mg/dl, p=0.04). There was no significant rise in LDH levels in survivors (from 829.59±499 U/L to 1018.6±468 U/L, p=0.20) while it increased significantly in non-survivors (from 816.2±443.08 U/L to 1056.61±480.54 U/L, p=0.003). The decrease in lymphocyte count and increase in D-Dimers in both the groups was significant (p=0.001). There was no significant elevation in ferritin in both the groups (p>0.05). Conclusion: In severe COVID-19 patients, serum CRP and LDH can be used for risk stratification and predicting survival. Lymphopenia, increase in serum ferritin and D-dimers may not predict survival.

Introduction Crimean-Congo hemorrhagic fever (CCHF) is a widespread tick-borne zoonotic disease. Sporadic outbreaks of CCHF occur in endemic regions, including Pakistan. The clinical spectrum of the illness varies from asymptomatic seroconversion to severe disease which may end in death. The treatment is supportive, including blood and blood products. There is multi-organ involvement in CCHF including acute hepatitis, thrombocytopenia, coagulopathy, acute kidney injury (AKI), and encephalopathy. Hematological and biochemical parameters may identify patients at substantial risk of worse outcomes. Early detection of the disease and forecasting the clinical course may be helpful. This case series aims to evaluate the trends of hematological and biochemical parameters among the survivors and non-survivors of CCHF. Methods All consecutive patients aged 16 years and above admitted to the isolation unit of Hayatabad Medical Complex, Peshawar, Pakistan between 1st July and 30th July 2022 with the diagnosis of CCHF were included in this case series. The diagnosis of CCHF was made by detecting viral ribonucleic acid by a polymerase chain reaction. For all patients, age, gender, address, occupation, clinical presentation, history of contact with animals, and travel history were recorded. All the vitals were taken regularly. The hematological (complete blood count) and biochemical parameters (serum creatinine, alanine aminotransferase (ALT), and C-reactive protein (CRP)) were documented daily. The blood group was determined for all the cases. Results Out of 17 cases, the majority (16 cases, 94.1%) were male and butchers (eight cases, 47.1%) by profession. All cases had significant contact with animals. Four patients (23.5%) died. Three out of the four non-survivors (75%) had ALT < 5 times the upper limit of normal with a static pattern of liver enzymes without much decline in ALT till death. One non-survivor (25%) had marked elevation of ALT at presentation, which had a declining trend till death. Seven out of 13 survivors (53.8%) had moderate to marked elevation in the level of ALT at presentation. The ALT showed a downward trend during the course of illness in all these patients. The remaining survivors (six out of 13, 46.2%) had a mild elevation of ALT and 50% of them showed improvement in the ALT level during hospitalization. All patients had thrombocytopenia at presentation. None of the non-survivors showed a persistent increase in the platelet count, and three cases remained severely thrombocytopenic at the time of death. However, the trend in platelet count among all the survivors was increasing. The CRP level in the majority (three out of four cases, 75%) of the non-survivors remained elevated till death, while all survivors showed a progressive decline in CRP level. A majority (11 out of 17 cases) had blood group B. Half of the non-survivors (two out of four cases) and the majority of the survivors (nine out of 13 cases) had blood group B. AKI was found in all non-survivors, while all the survivors had normal renal function throughout the course. Conclusion A persistently raised ALT and CRP level, a persistently low or decreasing platelet count, and AKI were associated with mortality. Blood group B was the commonest blood group among patients of CCHF, which is not reflective of the blood group distribution of the general population from which this case series has been reported.
RESUMEN
In developing countries, infectious diseases are thriving due to poor hygiene, inadequate public health infrastructure, and socio-cultural factors. Generally, infections are due to a single pathogen, but due to the shared risk factors for transmission, co-infections are not uncommon. The severity and outcome of infections are adversely affected by co-infection. Co-infections present as diagnostic and therapeutic enigmas because of the complex interaction between different pathogens involved and distorted host responses. The southeast Asian region, particularly Pakistan, is known for unique combinations of different infections. We present a distinctive case of triple co-infection of dengue virus, Crimean-Congo hemorrhagic fever virus, and severe acute respiratory syndrome coronavirus-2. The index case was a 60-year-old gentleman who presented with fever, cough, shortness of breath, bruises, and hemoptysis. He had thrombocytopenia, deranged liver and renal function, coagulopathy, and infiltrates in both lung fields. Subsequent investigations revealed a positive polymerase chain reaction for ribonucleic acid of dengue virus, Crimean-Congo Hemorrhagic fever virus, and severe acute respiratory syndrome coronavirus-2. He received supportive treatment including antibiotics, blood products, ribavirin, and supplemental oxygen. He developed multi-organ failure and succumbed to the triple co-infection. This case will act as a wake-up call for clinicians, public health authorities, and infectious disease specialists to plan before the volcano of co-infections erupts.
RESUMEN
Viruses have been implicated in the causation of several systemic illnesses, either directly or by immune modulation. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not an exception. Due to altered immune regulation, it is often associated with novel clinical manifestations and complications which have not been reported before. SARS-CoV-2 induces a pro-inflammatory state which makes the patient vulnerable to developing a variety of previously unreported adverse reactions to medications. Coronavirus disease 2019 (COVID-19) and its treatment have provided a fertile ground for various opportunistic infections including mucormycosis. The standard treatment for mucormycosis is surgical debridement and liposomal amphotericin B. Triazole antifungals such as posaconazole and isavuconazonium are the second-line agents for those intolerant to first-line therapy. Posaconazole is safer than amphotericin B as far as renal adverse effects are concerned. We report the case of a 60-year-old lady with type 2 diabetes mellitus, hypertension, ischemic heart disease, and osteoarthritis. She had severe COVID-19 requiring non-invasive ventilation four months ago. She presented with right rhino-orbital swelling, diplopia, and serosanguinous discharge from the right nostril. She had right third, sixth, and seventh cranial nerve palsies. Magnetic resonance imaging revealed right maxillary, ethmoid, and frontal sinusitis. Biopsy from the right nostril confirmed mucormycosis. Having normal renal and liver functions, she was started on oral posaconazole as she had an allergic reaction to a test dose of 1 mg amphotericin B (non-liposomal) in 20 mL of 5% dextrose water infused over 30 minutes. On day five, she developed acute kidney injury requiring renal replacement therapy. Her posaconazole was stopped. As she was not improving with conservative treatment, an ultrasound-guided, percutaneous renal biopsy was performed from the left kidney. The renal biopsy revealed thrombotic microangiopathy. She was started on liposomal amphotericin B as decided by the multidisciplinary team. Her renal function improved, and she continued on liposomal amphotericin B. We conclude that thrombotic microangiopathy, in this case, was likely due to posaconazole. This is a novel adverse effect presumably of posaconazole. This case report will alert physicians to be vigilant of the renal adverse effects of posaconazole in patients who have had COVID-19. Patients who develop renal injury while on posaconazole should undergo an early renal biopsy to ascertain the exact histopathology.
RESUMEN
Infectious agents have been implicated in the pathogenesis of autoimmune disorders for decades. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is no exception. This became evident as the pandemic evolved. Once considered a respiratory pathogen only, SARS-CoV-2 is now linked to a variety of autoimmune rheumatic disorders such as rheumatoid arthritis, systemic lupus erythematosus, reactive arthritis, spondyloarthropathies, vasculitis, and inflammatory myopathy. Although the exact cause for muscle injury in the setting of coronavirus disease 2019 (COVID-19) is not established, autoimmune inflammatory damage is the most accepted mechanism. Moreover, SARS-CoV-2 can cause direct muscle damage and indirectly through a cytokine storm. Inflammatory polymyositis in relation to COVID-19 has seldom been reported in developing countries. Here, we report a unique case of inflammatory polymyositis in a 52-year-old lady. The patient presented with muscle weakness, generalized body aches, and fatigue occurring four months after recovering from mild COVID-19. She had muscle weakness of Medical Research Council (MRC) grade 3/5 involving the shoulders and pelvic girdle with elevated muscle enzymes. Electromyography revealed an active irritable myopathic process consistent with inflammatory polymyositis. She underwent magnetic resonance imaging-guided muscle biopsy from the right thigh which revealed findings consistent with inflammatory myopathy. She was offered prednisolone and azathioprine. After four weeks of treatment, she had a remarkable improvement in her muscle strength to MRC grade 5/5.
RESUMEN
Hypoxemic respiratory failure is the most frequent complication of severe acute respiratory syndrome corona virus-2 (SARS-CoV-2) infection. Coronavirus disease-19 (COVID-19) is no longer considered a standalone respiratory infection. It can involve other organs, including kidneys by direct invasion or indirectly through immune activation, cytokine storm, microthrombi and hemodynamic instability. Multiorgan involvement carries a worse prognosis in COVID-19. Tubulopathy is the most frequently reported renal pathology, followed by glomerulopathies. Among the glomerulopathies, immunoglobulin A (IgA) nephropathy is less often reported. Differentiating tubulopathy from glomerulopathy is important from the management and prognostic point of view. Laboratory investigations, including urine microscopy, cannot predict glomerulopathy as a cause of renal involvement. Therefore, it is important to proceed with renal biopsy early to make a definite diagnosis. We report a case of a 33-year-old male who presented three weeks after recovery from COVID-19 with proteinuric acute kidney injury. Subsequent renal biopsy revealed IgA nephropathy.
RESUMEN
Water-borne infections like typhoid fever are common in the developing world. The emergence of extensively drug-resistant Salmonella typhi (XDR S. typhi) is of great concern for both local and global public health. Fever, diarrhea, and abdominal pain are the commonest manifestations of typhoid fever. Abdominal pain may be due to ileal and colonic inflammation/ulceration and mesenteric lymphadenitis. Sometimes, abdominal pain in typhoid is due to ileal perforation leading to peritonitis, and acute appendicitis which needs urgent surgical intervention. Delayed surgical intervention can result in morbidity and sometimes even death. We report a case of XDR S. typhi infection in a 17-year-old female who presented with fever and abdominal pain. During the course of the hospital stay, while she was on appropriate antibiotics, her abdominal pain worsened due to acute appendicitis. She underwent an appendectomy and had an uneventful recovery. This is the first case, to our knowledge, of acute appendicitis caused by XDR S. typhi. Although appropriate antibiotics are the mainstay of treatment for typhoid fever, physicians should be mindful that surgical consultation may be necessary in certain cases.
RESUMEN
Infectious diseases like malaria, typhoid, leptospirosis, and dengue fever are the leading causes of morbidity and mortality in developing countries like Pakistan. Although rare, it is possible to have coinfection with organisms that are endemic in a region, causing diagnostic and therapeutic dilemmas. Leptospirosis is caused by Gram-negative spirochetes. Leptospira are widely distributed and are transmitted by contamination of water and food by the urine of infected animals like rodents. Leptospirosis is characterized by fever, body aches, abdominal pain, and hepatic and renal involvement. Laboratory abnormalities include cytopenia, elevated bilirubin, alanine aminotransferase, and abnormal renal function tests. Typhoid fever is caused by Salmonella typhi (S. typhi), which is transmitted by fecal contamination of drinking water and food items. The clinical manifestations of typhoid fever include fever, abdominal pain, and diarrhea. Laboratory abnormalities include cytopenia and mildly deranged liver function tests. A strain of S. typhi resistant to all antibiotics except azithromycin and carbapenems was isolated in 2016 in Pakistan. Most of the clinical manifestations and laboratory abnormalities of leptospirosis and typhoid fever overlap. There have been case reports of coinfection of S. typhi and Leptospira, but there is no report of coinfection of extensively drug-resistant (XDR) S. typhi and Leptospira. We present a case of a 20-year-old man with fever, loose motions, and jaundice from Peshawar, Pakistan who had coinfection of Leptospira and XDR S. typhi. The attending physicians should adopt Hickam's dictum instead of Occam's razor approach.
RESUMEN
OBJECTIVE: To determine the effects of tocilizumab (TCZ) on inflammatory markers, laboratory indices; and short-term outcome in patients with severe COVID-19. STUDY DESIGN: Cross-sectional analytical study. Place and Duration of the Study: Hayatabad Medical Complex, Peshawar, Pakistan from 10th June till 31st August 2020. METHODOLOGY: Fifty-four patients with severe COVID-19 fulfilled the inclusion criteria and were included. All patients had received TCZ (4 mg/kg) in addition to standard treatment. Serum C-reactive protein (CRP), lactate dehydrogenase (LDH), D-dimer levels, full blood count, and liver function tests (LFTs) were checked before and 24 hours after receiving TCZ. Short-term outcome, defined as survival at day 28, was determined from hospital record/telephonic contact. Paired t-test was employed to assess the statistical significance of mean differences between the pre- and post-TCZ variables, considering a p-value of <0.05 as significant. RESULTS: Overall, the mean pre- and post-TCZ CRP was 18.7 ± 10.7 and 10.2 ± 8.6 mg/dl (p <0.001). It was 18.0 ± 10.3 and 10.3 ± 8.8 mg/dl (p=0.003) in survivors; and 19.4 ± 11.4 and 10.2 ± 8.7 mg/dl (p=0.005) in non-survivors, respectively. Overall, mean D-dimer level decreased from 12.5 ± 23 to 10.3 ± 12.2 µg/ml following TCZ (p=0.643); it decreased from 15.8 ± 29.8 to 11.4 ± 10.6 µg/ml (p=0.612) in survivors; and 9.0 ± 12.8 to 9.2 ± 14.1 µg/ml (p=0.961) in non-survivors, respectively. There were no significant differences in the pre- and post-TCZ LDH levels overall and between the groups. The 28-day mortality was 46.3%. CONCLUSION: Tocilizumab results in a significant reduction in CRP, while mean change in LDH and D-dimers was not substantial. The mean change in inflammatory markers did not predict survival. Key Words: Tocilizumab, COVID-19, Biomarkers, Outcome, Mortality.

OBJECTIVES: To determine the association between ABO/Rh-D blood types and susceptibility to SARS-CoV-2 infection in Pakistan. METHODS: In this cross-sectional study, 1935 confirmed cases of COVID-19 were included using consecutive sampling. Age and gender-matched sample of 1935 blood donors was used as a comparison group. Chi-square test and binary logistic regression were used for inferential statistics. RESULTS: Significantly higher proportion of blood type-B was observed in COVID-19 group (35.9% vs 31.9%, p=0.009). Blood type-AB was found more frequently (14.2% vs 11.8%, p=0.03) in the comparison group. The Rh-D Positive blood types were 93.3% in COVID-19 group and 94.9% in comparison group (p=0.03). The odds of blood type-B, AB and Rh-D positive to test positive for SARS-CoV-2 were 1.195 (95% CI 1.04 - 1.36, p=0.009), 0.80 (95% CI 0.66 - 0.97, p=0.03) and 0.75 (95% CI 0.57- 0.98, p = 0.03), respectively. Blood types A and O did not have significant association with SARS-CoV-2 PCR result (p = 0.22 and 0.88, respectively). CONCLUSIONS: There is significant association between blood types B & AB and susceptibility to COVID-19. There is no association between blood types A and O with COVID-19. Rh- D positive blood types are less susceptible to COVID-19.
RESUMEN
In South Asia, infectious diseases are associated with significant morbidity and mortality. Malaria, typhoid, and dengue are the most common infectious diseases, and patients may be co-infected with these diseases, resulting in diagnostic and treatment dilemmas. Dengue is caused by the Arboviridae family of viruses and is transmitted by Aedes aegypti. Dengue virus has four serotypes and the symptoms of dengue fever mimic those of other infectious diseases such as malaria, chikungunya, Zika virus disease, influenza A, enteric fever, and coronavirus disease 2019, which are also prevalent in areas of frequent dengue fever outbreak. Dengue fever is characterized by fever, severe myalgia, retro-orbital pain, skin rashes, and bone pain, which is why dengue fever is also referred to as breakbone fever. Patients with secondary dengue virus infection more commonly present with abdominal pain when compared with those with primary dengue virus infection. Salmonella typhi causes enteric fever, which is a human infection with no animal reservoir, but the symptoms of enteric fever closely resemble those of dengue fever. Concurrent infections with multiple organisms are especially difficult to diagnose. In this report, we present the case of a 15-year-old boy from Peshawar, Pakistan, who was co-infected with the dengue virus and extensively drug-resistant Salmonella typhi. To the best of our knowledge, this is the first reported case of co-infection with dengue virus and extensively drug-resistant Salmonella typhi.
RESUMEN
Objective To determine the mortality of patients with severe COVID-19 in the intensive care unit (ICU) in relation to age, gender, co-morbidities, ventilatory status, and length of stay (LOS). Methods This was a cross-sectional study based on data retrieved for 204 patients admitted to the ICU of Hayatabad Medical Complex, Peshawar, Pakistan, from April to August 2020. Study variables were age, gender, co-morbid conditions, ventilatory status, and length of stay (LOS). The data were analyzed using SPSS version 21 (IBM Corp., Armonk, NY). The independent t-test and the chi-square test were used to compare the means and frequencies of variables. Multivariate regression analysis was used to predict the likelihood of mortality. Results The overall mortality was 77%. Non-invasive ventilation (NIV) was administered to 61.8% of patients. Mortality was higher for invasive mechanical ventilation (IMV) (93.6% vs 66.7%, p<0.001) and for over 60 years (87.3% vs 72.3%, p=0.019). Mortality without co-morbidities was 75.2%. Comparative mortality rates for at least one co-morbidity (79.7%), diabetes mellitus (80.0%), hypertension (100%), diabetes mellitus and hypertension both (87.1%), and chronic obstructive pulmonary disease (75%) were insignificant. The LOS for survivors was longer (8.9±8.9 versus 5.4±5.2 days, p=0.017). The LOS < 24h was associated with higher mortality (85.9% vs 72.9%, p=0.040). On multivariable regression, the likelihood of mortality was high for IMV (7.330, 95% CI 2.667 - 20.143, p<0.001) and elderly (>60 years) patients (2.607, 95%CI 1.063 - 6.394, p=0.036). Mortality decreased with LOS longer than 24h (0.412, 95%CI 0.173 - 0.982, p=0.045). Co-morbidities did not have any effect on mortality. Conclusions Age more than 60 years and IMV were independent risk factors for higher mortality. Longer ICU stay, specifically more than 24 hours, was associated with lower mortality but LOS less than 24 hours might not have a causal relationship with mortality. The odds of survival were not affected by co-morbidities.
RESUMEN
Objective In this study, we aimed at comparing the seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in healthcare workers (HCWs) in coronavirus disease 2019 (COVID-19) receiving and non-COVID-19 receiving hospitals in Peshawar, Pakistan. Methods This cross-sectional analytical study was conducted in a COVID-19 receiving hospital (hospital 'A') and a non-COVID-19 receiving hospital (hospital 'B'). Using stratified random sampling, 1,011 HCWs (439 from hospital 'A' and 572 from hospital 'B') were recruited to participate in the study. Immunoglobulin G/immunoglobulin M (IgG/IgM) antibodies were checked using Elecsys® (Roche, Basel, Switzerland) Anti-SARS-CoV-2 immunoassay. The chi-squared test was used to compare frequencies, and the binary logistic regression model was used to predict the association between study variables' seropositivity to SARS-CoV-2. A p-value of <0.05 was considered statistically significant. Results The overall seroprevalence to SARS-CoV-2 antibodies in the two hospitals was 30.76%. It was 28.2% in hospital 'A' and 32.7% in hospital 'B' (p=0.129). The seroprevalence in HCWs having direct contact with COVID-19 patients was higher (33.1%) in non-COVID-19 receiving hospital versus 23.8% in COVID-19 receiving hospital (p=0.034). Seroprevalence was highest among administrative staff (44.0%), followed by nurses (30.8%), residents (19.8%), and consultants (17.8%) (p=0.001). As compared to consultants, the administrative and nursing staff were 3.398 and 3.116 times more likely to have positive antibodies, respectively. There were no significant differences in the seroprevalence between the respective categories of staff of the two hospitals. Conclusions The non-COVID-19 receiving hospital had a higher proportion of seropositive HCWs than the COVID-19 receiving hospital. The HCWs in the non-COVID-19 receiving hospital who had direct contact with patients had significantly higher seroprevalence. Seroprevalence was highest for administrative staff followed by nursing staff, residents, and consultants. Regardless of the COVID-19 status of the healthcare facility, all HCWs shall be trained on, and consistently follow, the proper protocols for donning and doffing of personal protective equipment (PPE).
RESUMEN
OBJECTIVE: To determine the correlation of serum calcium with severity of acute ischaemic stroke. METHODS: This cross-sectional study was conducted at the Khyber Teaching Hospital, Peshawar, Pakistan, from January to September 2013, and comprised patients who had suffered ischaemic stroke. All patients aged above 18 years who had been diagnosed to have suffered ischaemic stroke through history, physical examination and computed tomography scan, and who were admitted within the first 72 hours of the onset of the illness were included. Serum calcium was obtained within 78 hours of the onset of stroke and the severity of stroke was assessed at the same time using the National Institute of Health Stroke score. RESULTS: Of the 138 patients, 71(51.4%) were women and 67(48.6%) men. The overall mean age was 61.09±11.93 years (range: 34-100 years). The mean National Institute of Health Stroke score was 17.77±7.73 (range: 2-35). Serum calcium of all patients was measured and adjusted for serum albumin level. The mean serum calcium level was 8.82±0.69 mg/dl (range: 6.84-10.48). Bivariate correlation was calculated for continuous data of serum calcium and National Institute of Health Stroke score. The overall Pearson's correlation coefficient was r= -0.237 (p=0.005). CONCLUSIONS: Lower serum calcium levels may be associated with more severe clinical findings at the onset of stroke.

BACKGROUND: Foot ulcers are one of the most important complications of diabetes mellitus and often lead to lower limb amputation. Diabetic foot ulcers are susceptible to infection. The objective of this study was to determine the frequency of common bacteria infecting these ulcers and their antibiotic sensitivity pattern. METHODS: This descriptive cross-sectional study was performed in the Departments of Medicine and Surgery, Khyber Teaching Hospital, Peshawar from April, 2011 to February, 2012. Specimens collected from ulcers of 131 patients were inoculated on Blood Agar and MacConkey Agar, and antibiotic sensitivity was tested using standard disc diffusion method. RESULTS: Out of 131, specimens from 120 patients yielded 176 bacteria. Sixty-six patients had monomicrobial infection while polymicrobial growth was obtained in 54 patients. Overall, Staphylococcus aureus (38.6%) was the most common isolate followed by Pseudomonas aeruginosa (27.3%). Staphylococcus aureus was most often sensitive to Moxifloxacin, Imipenem/Meropenem, Vancomycin and Linezolid while it showed varying sensitivity to Penicillins and Cephalosporins. 47.1% isolates of Staphylococcus aureus were resistant to Methicillin. Most of the gram negative rods were sensitive to Imipenem/Meropenem, Piperacillin-Tazobactam and Ticarcillin-Clavulanate. Majority of gram negative bacteria were found resistant to Cephalosporins and Moxifloxacin except Pseudomonas which showed variable sensitivity to Ceftriaxone, Ceftazidime and Moxifloxacin. CONCLUSIONS: Majority of isolates were found resistant to the commonly used antibiotics. Most commonly isolated bacterium, Staphylococcus aureus was most often sensitive to Moxifloxacin, Imipenem/Meropenem, Vancomycin and Linezolid, while majority isolated gram negative rods were sensitive to Imipenem/Meropenem, Piperacillin-Tazobactam and Ticarcillin-Clavulanate.

BACKGROUND: The prevalence of diabetes mellitus has risen exponentially over the last three decades, with resultant increase in morbidity and mortality mainly due to its complications. Limited data is available regarding the awareness and knowledge about these complications in our population. This study was carried out to evaluate the knowledge of diabetic complications in patients with diabetes mellitus. METHODS: This cross-sectional study was conducted in the Medical B Unit of Department of Medicine Khyber Teaching Hospital, Peshawar. All admitted diabetic patients above 15 years of age with duration of diabetes mellitus more than one year were included. RESULTS: Out of the 96 patients questioned, 58 were females and 38 were males. Mean age was 53.29 +/- 10.821 years while the mean duration of diabetes mellitus was 9.75 +/- 7.729 years. Of the total 76 (79.1%) of the patients were illiterate; 36 (37.50%) had good, 24 (25%) had average and 36 (37.50%) had poor knowledge about diabetic complications. Males and university graduate patients had slightly better knowledge. Between 50-60% patients were aware of different cardiac complications of diabetes mellitus. Awareness regarding other complications was foot ulcer/gangrene 70 (72.91%), poor wound healing 68 (70.83%), stroke 54 (56.25%), renal diseases 64 (66.66%), eye diseases 53 (55.20%), gastroparesis and other gastrointestinal problems 45 (46.87%), diabetic ketoacidosis 55 (57.29%), hypoglycaemia 50 (52.08%), lipid abnormalities 26 (27.08%) and symptoms of diabetic neuropathy ranging from 47-65%. CONCLUSIONS: Majority of diabetic patients are unaware of diabetic complications. Therefore, hospital and community based awareness programs should be launched to decrease the morbidity and mortality associated with diabetes mellitus.
