Invasive Fungal Infections in Under-Five Diarrheal Children: Experience from an Urban Diarrheal Disease Hospital.

Invasive fungal infections (IFIs) are opportunistic, especially in immunocompromised and hospitalized patients. Children with IFIs are more vulnerable to a fatal outcome. For early diagnosis and treatment, knowledge of the spectrum and frequency of IFIs among children is prerequisite. In this prospective observational study, we enrolled 168 children of 2-59 months old of either sex from March 2018 to December 2019 admitted to the Dhaka hospital, icddr,b. Study participants with suspected IFIs were with or without severe acute malnutrition (SAM) along with sepsis/pneumonia and fulfilled any of the following criteria: (i) failure to respond to injectable antibiotics, (ii) development of a late-onset hospital-acquired infection, (iii) needed ICU care for >7 days, (iv) took steroids/antibiotics for >2 weeks before hospitalization, and (v) developed thrush after taking injectable antibiotics. The comparison group included non-SAM (weight-for-length Z score ≥ -2) children with diarrhea and fever <3 days in the absence of co-morbidity. We performed real-time PCR, ELISA, and blood culture for the detection of fungal pathogen. Study group children with SAM, positive ELISA and PCR considered to have a IFIs. In the study group, 15/138 (10.87%) children had IFIs. Among IFIs, invasive candidiasis, aspergillosis, histoplasmosis detected in 6 (4.53%), 11 (7.97%), and 1 (0.72%) children, respectively, and (3/15 [2.17%]) children had both candidiasis and aspergillosis. Children with IFIs more often encountered septic shock (26.7% vs. 4.9%; p = 0.013) and had a higher death rate (46.7% vs. 8.9%; p < 0.001) than those without IFIs. IFIs were independently associated with female sex (OR = 3.48; 95% CI = 1.05, 11.55; p = 0.042) after adjusting for potential confounders. Our findings thus implicate that, malnourished children with septic shock require targeted screening for the early diagnosis and prompt management of IFIs that may help to reduce IFIs related deaths.

Clinical profile of HIV/AIDS-infected patients admitted to a new specialist unit in Dhaka, Bangladesh--a low-prevalence country for HIV.

This paper describes the clinical features of a series of patients admitted to the specialist HIV/AIDS unit (Jagori) of the Dhaka Hospital, ICDDR,B (International Centre for Diarrhoeal Disease Research, Bangladesh) during May 2008-February 2010. Data were collected from a review of documents and electronic case-records and collation of laboratory results with respect to CD4 counts. One hundred and nine patients were admitted during this period. Their mean age was 33.4 years, and 62% were male. On admission, the mean CD4 count +/- standard deviation (SD) was 244 +/- 245 (range 2-1,549). The death rate was 12%. The patients were classified as World Health Organization clinical stage 1: 23%, stage 2: 30%, stage 3: 23%, and stage 4: 24% during the admission. The commonest diagnosis recorded was tuberculosis (TB) (23%), which was also the commonest cause of death (38%). Even for those clinicians with limited experience of managing AIDS cases, the commonest problem encountered in this patient group was TB, reflecting the continued high burden of TB on health services in Bangladesh. Additional challenges to managing TB/HIV co-infection include atypical presentations in HIV-infected persons and the complex drug interaction with antiretroviral therapy.

Prevalence of infections, HIV risk behaviors and factors associated with HIV infection among male injecting drug users attending a needle/syringe exchange program in Dhaka, Bangladesh.

Injecting drug users (IDU) in Bangladesh are at the early stages of an HIV epidemic. To understand the dynamics of the HIV epidemic, male IDU (n = 561) were recruited from the needle/syringe exchange program in Dhaka in 2002, who underwent a risk-behavior survey and were tested for HIV, syphilis, hepatitis C, and hepatitis B. Correlates of HIV infection were determined by conducting bivariate and multiple regression analyses. The median age of the IDU was 35 years, 39.6% had no formal education, approximately half were married and/or living with their regular sex partner and 26% were currently homeless. The median age at first injection was 29 years. HIV was detected in 5.9% of the IDU and homelessness was the only factor independently associated with HIV (OR = 5.5). Urgent measures must be undertaken to prevent escalation of the HIV epidemic. The study's limitations are noted.

Clinical profile of hospitalized HIV-infected children in Bangladesh, a low-HIV-prevalence country.

BACKGROUND: Bangladesh has a low HIV prevalence and data on the risk factors and clinical presentation of HIV-infected children are lacking. OBJECTIVE: To describe the clinical characteristics of hospitalized HIV-infected children in Bangladesh and determine the factors associated with a low CD4 count. METHODS: An anonymous, retrospective review was undertaken of the medical records of all patients admitted to the HIV unit of the iccdr,b Dhaka Hospital between February 2009 and July 2012. Demographic, clinical and laboratory data were extracted from the electronic medical record system. HIV-infected children with a low absolute CD4 count (<200 cells/µl) were compared with HIV-infected children with a CD4 count ≧200 cells/µl. RESULTS: Of 266 HIV-infected patients, 24 were children (9%), 13 (54%) of whom were male. Ages ranged from 2 to 17 years (median 7). Of the 21 (88%) children who acquired the infection by vertical transmission, median age at diagnosis was 5·2 years, and the parents of 19 (79%) reported a history of external migration. Children commonly presented with prolonged fever (n = 14, 58%), recurrent cough (n = 14, 58%), failure to thrive (n = 11, 46%) and recurrent diarrhoea (n = 4, 17%). Six (25%) patients had tuberculosis, four (16·7%) had herpes zoster and four (16·7%) were diagnosed with Pneumocystis jirovecii pneumonia. One child died during hospitalization. Children with a low CD4 count (<200 cells/µl) more often had severe wasting (95% CI 1·2-453·97) and severe under-nutrition (95% CI 1·39-196·25) than those with a higher CD4 count*. CONCLUSION: The majority of HIV-infected children presenting to an inpatient speciality ward in Dhaka acquired HIV through vertical transmission, and most of the parents had a history of external migration. Further studies are needed to determine the optimal strategy for preventing mother-to-child transmission and for early identification and treatment of HIV-infected children in this low-prevalence country.

Characteristics and predictors of death among hospitalized HIV-infected patients in a low HIV prevalence country: Bangladesh.

BACKGROUND: Predictors of death in hospitalized HIV-infected patients have not been previously reported in Bangladesh. OBJECTIVE: The primary aim of this study was to determine predictors of death among hospitalized HIV-infected patients at a large urban hospital in Bangladesh. METHODS: A study was conducted in the HIV in-patient unit (Jagori Ward) of icddr,b's Dhaka Hospital. Characteristics of patients who died during hospitalization were compared to those of patients discharged from the ward. Bivariate analysis was performed to determine associations between potential risk factors and death. Multivariable logistic regression was used to identify factors independently associated with death. RESULTS: Of 293 patients admitted to the Jagori Ward, 57 died during hospitalization. Most hospitalized patients (67%) were male and the median age was 35 (interquartile range: 2-65) years. Overall, 153 (52%) patients were diagnosed with HIV within 6 months of hospitalization. The most common presumptive opportunistic infections (OIs) identified were tuberculosis (32%), oesophageal candidiasis (9%), Pneumocystis jirovecii pneumonia (PJP) (8%), and histoplasmosis (7%). On multivariable analysis, independent predictors of mortality were CD4 count ≤200 cells/mm3 (adjusted odds ratio [aOR]: 16.6, 95% confidence interval [CI]: 3.7-74.4), PJP (aOR: 18.5, 95% CI: 4.68-73.3), oesophageal candidiasis (aOR: 27.5, 95% CI: 5.5-136.9), malignancy (aOR:15.2, 95% CI: 2.3-99.4), and bacteriuria (aOR:7.9, 95% CI: 1.2-50.5). Being on antiretroviral therapy prior to hospitalization (aOR: 0.2, 95% CI: 0.06-0.5) was associated with decreased mortality. CONCLUSION: This study showed that most patients who died during hospitalization on the Jagori Ward had HIV-related illnesses which could have been averted with earlier diagnosis of HIV and proper management of OIs. It is prudent to develop a national HIV screening programme to facilitate early identification of HIV.
