Exploring the Impact of Factors Affecting the Lifespan of HIVs/AIDS Patient’s Survival: An Investigation Using Advanced Statistical Techniques

This study investigates the impact of various factors on the lifespan and diagnostic time of HIV/AIDS patients using advanced statistical techniques. The Power Chris-Jerry (PCJ) distribution is applied to model CD4 counts of patients, and the goodness-of-fit test confirms a strong fit with a p-value of 0.6196. The PCJ distribution is found to be the best fit based on information criteria (AIC and BIC) with the smallest negative log-likelihood, AIC, and BIC values. The study uses datasets from St. Luke hospital Uyo, Nigeria, containing HIV/AIDS diagnosis date, age, CD4 count, gender, and opportunistic infection dates. Multiple linear regression is employed to analyze the relationship between these variables and HIV/AIDS diagnostic time. The results indicate that age, CD4 count, and opportunistic infection significantly impact the diagnostic time, while gender shows a nonsignificant relationship. The F-test confirms the model's overall significance, indicating the factors are good predictors of HIV/AIDS diagnostic time. The R-squared value of approximately 72% suggests that administering antiretroviral therapy (ART) can improve diagnostic time by suppressing the virus and protecting the immune system. Cox proportional hazard modeling is used to examine the effects of predictor variables on patient survival time. Age and CD4 count are not significant factors in the hazard of HIV/AIDS diagnostic time, while opportunistic infection is a significant predictor with a decreasing effect on the hazard rate. Gender shows a strong but nonsignificant relationship with decreased risk of death. To address the violation of the assumption of proportional hazard, the study employs an assumption-free alternative, Aalen’s model. In the Aalen model, all predictor variables except age and gender are statistically significant in relation to HIV/AIDS diagnostic time. The findings provide valuable insights into the factors influencing diagnostic time and survival of HIV/AIDS patients, which can inform interventions aimed at reducing transmission and improving early diagnosis and treatment. The Power Chris-Jerry distribution proves to be a suitable fit for modeling CD4 counts, while multiple linear regression and survival analysis techniques provide insights into the relationships between predictor variables and diagnostic time. These results contribute to the understanding of HIV/AIDS patient outcomes and can guide public health interventions to enhance early detection, treatment, and care.

Objective:To determine the seroprevalence of anti-Toxoplasma gondii(T.gondii) IgG and IgM antibodies in HIV/AIDS patients and uninfected subjects.Methods:This cross sectional survey was carried out on 78 healthy and 62 HIV^+/AIDS individuals in northern ban between September 2007 and October 2008.Five mL of blood samples were collected from each person in case and control groups.Determination of CD4^+ counts was performed by flow cytometry.The serum separated from blood samples was evaluated by conventional ELISA technique to determine the presence of antibodies to T.gondii.Results:Forty eight out of 62(77.4%) HIV/AIDS serum samples were found positive for anti-T.gondii IgG antibody,compared with 59 among 78(75.6%) HIV negative samples from the same area(P】0.05).Six out of 62(9.7%) HIV^+/AIDS patients showed anti-T.gondii IgM antibody in their serum samples,compared with 7 among 78(9%) HIV negative samples(P】0.05).The mean of CD4^+ counts in HIWAIDS was(430.8±182.3) cells/μL and in control group was(871.0±243.3)%cells/μL(P【0.01).CD4^+ estimation in 5(11.1%) of HIV^+/AIDS patients was 【200 cells/μL(P【0.000 1).Conclusions:Seroprevalence of latent toxoplasmosis in HIV patients is high,therefore the prevention of toxoplasmic encephalitis,administration of primary prophylaxis with co-trimoxazole to all HIV^+/AIDS patients are necessary.

Investigation and Analysis on Pathogen Distribution of HIV/AIDS Patients with Opportunistic Infection

Objective: This study aims to understand the distribution of pathogenic bacteria in the region of HIV/AIDS patients with opportunistic infection. Methods: To count the number of the bacterial culture of HIV/AIDS patients in our hospital from October 2011 to December 2014, and observe the distribution of all kinds of pathogenic bacteria. Results: From the 4269 cases of HIV/AIDS patients’ bacteria, 5045 cases were cultured whose main flora distribution wasCandida albicans, 1759 cases. The second one was penicillium, 982 cases. The third one was mycobacteria, 557 cases. And then there are 213 cases ofCryptococcus neoformans, 212 cases of?Klebsiella pneumonia, 209 cases of?E. coli, 157 cases of coagulase-negative staphylococci, 112 cases of?Candida tropicalis, 90 cases of glabrata, 81 cases of?Staphylococcus aureus, 75 cases of?Pseudomonas aeruginosa, 60 cases of Salmonella, 48 cases of Acinetobacter and the distribution of the rest of cultured bacterial was less than 40 cases. Conclusion: There are many kinds of types of Pathogenic bacteria in HIV/AIDS patients with the opportunity to infectious. And the majorities are?Candida albicans,?Penicillium marneffei,?Penicillium,?Mycobacterium,?Cryptococcus neoformans?and so on. The infection sites are widely distributed;respiratory and circulatory are the main infected system. Improving the detection rate and reducing the contamination rate can truly reflect the distribution of pathogenic bacteria, and the distribution can guide the infection work in hospital. At the same time, it’s good to predict and prevent opportunistic infection. Thus, the patients can get immediate treatment.

Correlation between Abdominal Ultrasonographic Findings and CD4 Cell Count in Adult Patients with HIV/AIDS in Jos, Nigeria

Acquired Immunodeficiency Syndrome (AIDS) is caused by Human Immunodeficiency Viruses (HIV) resulting in progressive destruction of cell mediated immunity. The abdominal manifestations of AIDS are related to the level of CD+4 cells count as well as viral load. Abdominal ultrasound examination is easy to perform, non-invasive, inexpensive, readily available and reproducible investigation which provides valuable information about abdominal findings in AIDS. The objective of the study was to evaluate abdominal ultrasound findings in adult HIV/AIDS patients in Jos, Plateau State, Nigeria and correlate these findings with the patients’ CD+4 counts. A cross-sectional study of abdominal ultrasound findings of adult patients with HIV/AIDS was conducted over a period of six months. The abdominal ultrasound findings and CD+4 counts were studied. Two hundred (40%) of the patients had normal abdominal ultrasound, while 60% (300) had various abnormalities. The common abnormalities included increased liver parenchymal echogenicity in 25.0%, hepatomegaly in 23.4%, splenomegaly in 6.6%, increased splenic echogenicity in 6.2% and thickened gallbladder wall in 12.6%, elevated renal parenchymal echogenicity in 6.4%, enlarged kidneys in 2.6%, lymphadenopathy in 6.0%, and ascites in 2.4%. Pelvic abscess was the least pathology in 0.2%. Most of the findings did not correlate with the patients’ CD+4?count except for lymphadenopathy and ascites. Although abdominal ultrasound examination is invaluable in the management of these patients, however, it has not shown to be useful in predicting the patients’ immune status.

A comparative study of bacterial isolates from the urine samples of AIDS and non-AIDS patients in Benue,Nigeria

Objective:To determine the common bacterial causes of urinary tract infection and their antibiotic susceptibility pattern in AIDS patients versus non-AIDS patients.Methods:One thousand consecutive AIDS patients with signs and symptoms of AIDS and non-AIDS patients (served as control) each on admission were recruited into the study between January 2005 to January 2008,in Federal Medical Center,Makurdi.Urine samples were collected with sterile universal bottles and analysed with appropriate laboratory methods and antibiotic susceptibility test was carried out by disk diffusion technique in accordance with National Committee for Clinical Laboratory Standards(NCCLS,now CLSI) criteria.The results were analysed using SPSS 11.0 statistical software.Results:Urine samples of AIDS patients with urinary infection had a more spectrum of micro-organisms including Candida organisms,Pseudomonas aeruginosa and Staphylococcus aureus.Ceftriaxone,Ceftazidime or Ciprofloxacin had a remarkably high anti-bacterial activity across the two study groups.A general resistance was recorded in ampicillin.tetracycline and co-trimoxazole.There was no significant difference in antibiotic susceptibility patterns between AIDS and non- AIDS patients(P】0.05).Conclusions:A reduction in unnecessary use of antibiotics as well as infection control should be encouraged in our health facilities.

HIV/AIDS related mortality among adult medical patients in a tertiary health institution in South-South,Nigeria

Objective:To determine the causes of death among human immunodeficiency virus/acquired immunodeficiency syndrome(HIV/AIDS) patients as a step to planning strategies to improve mortality from this condition.Methods:This study retrospectively analyzed the mortality pattern of adult HIV/AIDS patients in the University of Calabar Teaching Hospital from January 2005 to December 2007.The data were obtained from sexually transmitted infection/acquired immunodeficiency syndrome(STI/AIDS) clinic register,admissions and discharge/death registers as well as the patients’ case records and the hospitals monthly mortality reviews.Information obtained included age,sex,diagnosis and cause(s) of death.The causes of death considered were the direct causes of death,since the originating antecedent cause of death is the same in all the patients,in this case,HIV/AIDS.Data was analysed using Epi Info 2002.Results:The total number of mortalities during the study period was 350,100 were HIV positive representing 28.6%of all deaths.While advanced HIV/AIDS disease was the leading cause of death in our study representing 27.0%,tuberculosis was the single leading cause of deaths in HIV/AIDS patients constituting about 24.0%of deaths.This was followed by sepsis and septicaemia(13.0%), meningitis and encephalitis,and anaemia accounting for 11.0%,while respiratory diseases constituted 5.0%of the mortality burden.The highest number of deaths occurred in those aged between 21-50 years(82.0%).Conclusions:The study has shown that HIV/AIDS is a major cause of morbidity and mortality in our hospital.The causes of death reflect the varied spectrum of infection and other forms of organ involvement that affect HIV/AIDS patients.The present dismal situation of adult patients living with HIV/AIDS calls for enhanced strategies to decrease the mortality trend observed in Nigeria and sub-Saharan Africa.

High levels of Zinc-α-2-Glycoprotein among Omani AIDS patients on combined antiretroviral therapy

Objective:To investigate the levels of zinc-α-2-glycoprotein(ZAG) among Omani AIDS patients receiving combined antiretroviral therapy(cART).Methods:A total of 80 Omani AIDS patients(45 males and 33 females),average age of 36 vears.who were receiving cART at the Saltan Qaboos University Hospital(SQUH).Muscat,Oman,were tested for the levels of ZAG.In addition,SO healthy blood donors(46 males and 34 females),average age of 26 years,attending the SOUH Blood Bank,were tested in parallel as a control group.Measurement of the ZAG levels was performed using a competitive enzyme—linked immunosorbent assay and in accordance with the manufacturer's instructions.Results:The ZAG levels were found to he significantly higher among AIDS patients compared to the healthy individuals(P=0.033).A total of 56(70%) of the AIDS patients were found to have higher levels of ZAG and 16(20%) AIDS patients were found to have high ZAG levels,which are significantly(P>0.031) associated with weight loss.Conclusions:ZAG levels are high among Omani AIDS patients on cART and this necessitales the measurement of ZAG on routine basis,as it is associated with weight loss.

Analysis on Immune Tolerance and Resistance Mechanism of <i>Cryptococcus albidus</i>of AIDS Patients with Opportunistic Cryptococci Infection

Objective: To explore more about the immune tolerance and drug resistance of white Cryptococci albidus in AIDS patients with opportunistic Cryptococcus infection. Methods: To analyze drug resistance of the samples of white Cryptococcus albidus extracted from opportunistic infection AIDS patients in the certain infection area from October 2011 to December 2014. Results: After analyzing two samples of Cryptococcus albidus from 885 cases with opportunistic infection, we found that one of the samples do resist to ten common antibiotics. They were fluconazole, flu-cytosine, fluconazole, caspofungin, amphotericin B, MI miconazole, terbinafine, ketoconazole and itraconazole. The other one was sensitive to voriconazole, but resistant to the rest of the drug. Two strains of bacteria were inoculated into the animals in vivo and their DNA was extracted to carry out the genotyping analysis. The results showed that different degrees of resistance gene amplification bands were found in the 10 kinds of antibiotics. Conclusion: Although there were few opportunistic infection Cryptococcus albidus in AIDS patients, it was easy to show its resistance to drugs. Therefore, great attention should be paid to it for the medical workers.

Functional Health Literacy and Doctor-Patient Communication: Experiences of HIV/AIDS Patients in Homa Bay County, Kenya

Patient involvement in the health care process has been documented as a critical component of successful disease management. However, inadequate functional health literacy among patients is a well-known barrier to effective doctor-patient communication, which has an adverse effect on health outcomes. This study aimed at investigating the association of functional health literacy and doctor-patient communication among HIV/AIDS patients in Homa Bay County, Kenya. It was a cross-sectional hospital-based survey conducted among 362 HIV/AIDS patients receiving care at the eight sub-county hospitals of Homa Bay county. Data was collected using a self-administered structured questionnaire. Cronbach’s alpha and confirmatory factor analysis tests were used to ascertain the reliability and validity of study instruments, while Logistic regression logistic analysis was used to measure the association between functional health literacy and doctor-patient communication. 51% of the respondents were females, and the majority (30.9%) of respondents fell in the age group of 45 years and above. The respondents’ functional health literacy levels were inadequate at weighted means scores of 3.23 [SD 1.31]. The study further established that functional health literacy significantly influenced doctor-patient communication [Nagelkerke R square = 0.318]. There is, therefore, a need to document the determinants of functional health literacy to improve it and make doctor-patient interaction an enjoyable and meaningful experience.
