Skin manifestations of malnutrition in HIV-positive meningitis patients

The HIV/AIDS pandemic has led to a rise in the incidence of tuberculosis and an epidemic of co-infection in many developing countries. Treatment of Mycobacterium tuberculosis in persons with HIV infection presents several challenges to the clinician particularly in resource-poor countries. As will be discussed in this paper diagnosis of latent tuberculosis relies on tuberculin skin testing which has poor sensitivity and reproducibility in immunocompromised patients. The World Health Organization (WHO) recommends treatment of active tuberculosis as the primary means of global tuberculosis control. In practice treatment of active tuberculosis typically requires that a symptomatic patient self-report to a health service for evaluation and management. Even if this approach to tuberculosis control were sufficient many logistic and clinical problems remain involving tuberculosis diagnosis and therapy in the patient with HIV/AIDS. Recognizing the significant clinical and public health challenges surrounding the treatment of tuberculosis in patients with HIV infection this paper will address a number of issues relevant to the care of co-infected patients. These include current guidelines for the treatment of active tuberculosis as well as the diagnosis and treatment of latent tuberculosis in HIV-positive patients. The paper concludes with a discussion of promising new drugs for tuberculosis treatment. (excerpt)

Racial Disparities and Hospital Outcomes in Patients with HIV Undergoing Autologous Stem Cell Transplant. Analysis of the National Inpatient Sample (2016-2020)

BackgroundThe association of the anti-aquaporin-4 (AQP-4) water channel antibody with neuromyelitis optica (NMO) syndrome has been described from various parts of the world. There has been no large study describing this association from southern Africa, an HIV endemic area. HIV patients often present with visual disturbance or features of a myelopathy but seldom both either simultaneously or consecutively. We report our experience of NMO in the era of AQP-4 testing in HIV-positive and HIV-negative patients seen in KwaZulu-Natal, South Africa.MethodsA retrospective chart review was undertaken of NMO cases seen from January 2005 to April 2016 in two neurology units serving a population of 7.1 million adults. The clinical, radiological and relevant laboratory data were extracted from the files and analysed.ResultsThere were 12 HIV-positive patients (mean age 33 years), 9 (75%) were women and all 12 were black patients. Of the 17 HIV-negative patients (mean age 32 years), 15 (88%) were women and 10 (59%) were black people. The clinical features in the two groups ranged from isolated optic neuritis, isolated longitudinally extensive myelitis or combinations. Recurrent attacks were noted in six HIV-positive patients and six HIV-negative patients. The AQP-4 antibody was positive in 4/10 (40%) HIV-positive patients and 11/13 (85%) HIV-negative patients. The radiological changes ranged from longitudinal hyperintense spinal cord lesions and long segment enhancing lesions of the optic nerves. Three patients, all HIV-positive, had tumefactive lesions with incomplete ring enhancement.ConclusionThis study confirms the presence of AQP-4-positive NMO in southern Africa in both HIV-positive and HIV-negative patients. The simultaneous or consecutive occurrence of optic neuritis and myelitis in an HIV-positive patient should alert the clinician to test for the AQP-4 antibody. It is important to recognise this clinical syndrome as specific therapy is available. We further postulate that HIV itself may act as a trigger for an autoimmune process.

Distribution patterns of drug resistance Mycobacterium tuberculosis among HIV negative and positive tuberculosis patients in Western Kenya

The impact of HIV infection on malaria is unclear in nonendemic areas. In endemic territories, HIV has been reported to be a risk factor for higher morbidity. Nowadays, as HIV-infected patients travel more, it is important to assess the impact of HIV at the individual level on imported malaria. This retrospective case-control study collected data on HIV-infected patients diagnosed with malaria (2000-2017) and matched them with two controls based on age, sex and ethnicity. Clinical and biological parameters were collected and compared. We identified 47 cases and matched them with 94 controls. Comparing each of the WHO 2014 severity criteria, hyperparasitemia above 10% (P = 0.006; 12.8 versus 1.1%), icterus (P = 0.042; 14.9 versus 4.3%), acute renal failure (P = 0.022; 25.5 versus 9.6%) and bacteraemia (P = 0.014; 6.4 versus 0%) were significantly more present in HIV-infected patients with a trend to more cerebral malaria (12.8 versus 6.4%). HIV- infected patients were hospitalized more frequently and for longer periods. We observed a higher number of severity criteria when CD4 T-cell count was lower, especially below 200 cells/μl. The difference in occurrence of severe malaria disappeared when patients with CD4 T-cell count more than 500 cells/μl and undetectable viral load (n = 9) were compared with controls. De-novo HIV diagnosis was made during the malaria episode in 17% of cases. HIV infection has an impact on the imported malaria profile, although it is unclear whether well controlled HIV-infected patients have a higher risk of severe malaria. HIV-infected patients should be particularly targeted for pretravel advice.

Tunnelled catheters are used for dialysis in over 25% of haemodialysis (HD) patients and are a major risk factor for bacteraemia. HIV-positive patients may be at particularly increased risk of catheter-related bacteraemia (CRB) due to their immunocompromised state. The present case-controlled study compared catheter-related bacteraemia with HIV-positive and HIV-negative haemodialysis patients. Using a prospective computerized vascular access database, we identified 33 HIV-positive haemodialysis patients who had a tunneled dialysis catheter placed during a 6.5-year period. Their catheter outcomes were compared with those observed in 55 age-, sex- and access date-matched control haemodialysis patients. The two groups were similar in terms of age, sex, diabetes, hypertension and peripheral vascular disease, but the HIV patients were more likely to be black (94 vs 76%, P=0.03). CRB occurred in 52% of the HIV patients and 49% of the controls (P=0.83). The median infection-free catheter survival was similar in HIV-positive and negative patients (165 vs 119 days, P=0.12). Among patients with CRB, the likelihood of a Gram-negative infection was similar in both groups (18 vs 30%, P=0.37). However, polymicrobial CRB was more likely in HIV patients (41 vs 15%, P=0.049). HIV-positive patients were more likely to be hospitalized for treatment of CRB than HIV-negative patients (29 vs 7%, P=0.05). CRB is equally likely in HIV-positive and control haemodialysis patients. However, CRB is likely to be more severe in HIV-positive patients, as judged from the greater likelihood of polymicrobial infection and of hospitalization.

BackgroundMalaria and HIV/AIDS constitute major public health problems in Ethiopia, but the burden associated with malaria-HIV co-infection has not been well documented. In this study, the burden of malaria among HIV positive and HIV negative adult outpatients attending health facilities in Oromia National Regional State, Ethiopia was investigated.MethodsA comparative cross-sectional study among HIV-positive patients having routine follow-up visits at HIV care and treatment clinics and HIV-seronegative patients attending the general medical outpatient departments in 12 health facilities during the peak malaria transmission season was conducted from September to November, 2011. A total of 3638 patients (1819 from each group) were enrolled in the study. Provider initiated testing and counseling of HIV was performed for 1831 medical outpatients out of whom 1819 were negative and enrolled into the study. Malaria blood microscopy and hemoglobin testing were performed for all 3638 patients. Data was analyzed using descriptive statistics, Chi square test and multivariate logistic regression.ResultsOf the 3638 patients enrolled in the study, malaria parasitaemia was detected in 156 (4.3 %); malaria parasitaemia prevalence was 0.7 % (13/1819) among HIV-seropositive patients and 7.9 % (143/1819) among HIV-seronegative patients. Among HIV-seropositive individuals 65.4 % slept under a mosquito bed net the night before data collection, compared to 59.4 % of HIV-seronegative individuals. A significantly higher proportion of HIV-seropositive malaria-negative patients were on co-trimoxazole (CTX) prophylaxis as compared to HIV-malaria co-infected patients: 82 % (1481/1806) versus 46 % (6/13) (P = 0.001). HIV and malaria co-infected patients were less likely to have the classical symptoms of malaria (fever, chills and headache) compared to the HIV-seronegative and malaria positive counterparts. Multivariate logistic regression showed that HIV-seropositive patients who come for routine follow up were less likely to be infected by malaria (OR = 0.23, 95 % CI = 0.09–0.74).ConclusionThe study documented lower malaria prevalence among the HIV-seropositive attendants who come for routine follow up. Clinical symptoms of malaria were more pronounced among HIV-seronegative than HIV-seropositive patients. This study also re-affirmed the importance of co-trimoxazole in preventing malaria symptoms and parasitaemia among HIV- positive patients.

Background: More than 90% of human immunodeficiency virus (HIV+) infected patients develop skin lesions at some time throughout the course of the disease. Several skin diseases have proved to be sensitive and useful indicators of progression of HIV+ infection. Although these conditions may be seen in general healthy population, their occurrence in patients with acquired immunodeficiency syndrome is often atypical, more severe and explosive. Objective: The aim of the study was to assess the magnitude and prevalence of skin manifestation among HIV patients in JUSH ART Clinic. Methods: A retrospective study was conducted among HIV patients in JUSH ART Clinic using a structured data collection format and the data was collected from patient’s record (card) and was analyzed by using SPSS version 20. The result was presented using numbers, ratios and tables. Results: Of 268 HIV/AIDS, patients who have follow-up in Jimma University Specialized Hospital (JUSH) Antiretroviral therapy (ART) clinic 137 (51.1%) were having skin manifestations. The commonest type of skin lesion identified was Herpes Zoster, 74 (54%). This study showed that HIV positive (HIV+) patients with advanced stages of skin disorders had relatively lower CD4+ cell counts. Skin manifestation was significantly associated with WHO clinical stage with P=0.019 and CD4+ cell count with a P-value 0.0001. Conclusion: Skin diseases are highly prevalent among HIV- Positive patients and the frequency and number of these manifestations are well correlated to the patient’s immune status and World Health Organization (WHO) staging. Therefore, examination of skin disorders, as early diagnosis and management of skin problems will improve the quality of life in HIV positive patients.

BackgroundKaposi’s sarcoma (KS) is a multifocal angioproliferative tumor involving blood and lymphatic vessels, caused by Human Herpes Virus-8 (HHV-8). KS is an important AIDS-defining tumor with high prevalence in Sub-Saharan Africa, including Tanzania which has high HIV and HHV-8 sero-prevalence. It is critically important to monitor the prevalence of AIDS-defining tumors, such as KS, in the age of HIV/AIDS. We studied the prevalence of KS and associated risk factors among HIV-positive patients at Kilimanjaro Christian Medical Centre (KCMC), a referral hospital in northern Tanzania, over the period from January 2012 to December 2015.MethodsThis was a retrospective hospital-based cross-sectional study to determine the prevalence of KS among HIV/AIDS patients between 2012 and 2015. The study included 1100 HIV patients’ data which were collected at the Infectious Disease Clinic (IDC) from patients’ files. Stata version 13 (StataCorp LP, Texas 77,845 USA) was used for all statistical analyses. The prevalence of KS was calculated across levels of a number of categorical variables. Logistic regression was performed to determine relative risk of KS for all characteristics. We included all variables with p-values ≤10% in the multivariate analysis, including ART use, as this is considered to have an influence on KS. In the multivariate analysis, statistical significance was established based on a two-tailed p-value ≤5%. All patients’ notes were kept confidential as per the Helsinki declaration.ResultsOur results revealed a 4.6% prevalence of KS at KCMC hospital, between January 2012 and December 2015, 51(4.6%) patients were diagnosed with KS out of 1100 HIV-positive patients. The study further revealed that KS in HIV patients was most associated with low CD4 cell count (less than or equal to 200 cells/μl). Moreover, women were more likely than men to diagnosed with KS, with higher odds significantly associated with KS (OR 0.42, p < 0.009). Increased age, above 35 years, among the HIV seropositive patients was significantly associated with KS (OR 25.67, p < 0.007). HIV patients who were none smokers were more likely to suffer from KS compared to HIV smokers (OR 0.41, p < 0.010).ConclusionKS remains a common malignant vascular tumor commonly associated with HIV/AIDS in Tanzania. Our study highlights the need for continued efforts to combat HIV, as well as associated diseases such as KS. Continued availability of ART (Anti-Retroviral Therapy) to HIV/AIDS patients, and test reagents for CD4 cell count and viral load determination are important measures to alleviate the suffering of these patients. Furthermore, studies to gather more evidence on ART resistance are highly needed to guide treatment choices.

Background: Detection of Hepatitis B surface antibodies (anti-HBs) in the serum implies that an individual is immune to HBV infection either from vaccination or past infection, which usually persists for life. Aim: This study was aimed to determine the seropositivity of anti-HBs among HIV-seropositive patients and further appraise the effect of co-infection on their immunological status in Ojo, Lagos. Materials and Methods: A total of 74 blood samples collected from HIV positive patients were analysed for anti-HBs (HBsAb) by Immunochromatographic assay (Biotec, UK). CD4+ count was determined using BD FACS Count Automated analyser. Results: Out of the 74 HIV infected patients screened, 12 (16.2 %) males and 62 (83.8 %) females, 2 patients (2.7 %) were positive for anti-HBs, with no prevalence among the males and 2.7 % among the females. Anti-HBs was only recorded in HIV positive patients in the 21-30 years age group (8.7 %). The result showed anti-HBs lifelong protection to HBV among HIV patients with CD4+ Count ranging from 601-700 and 901-1000 to be 1.7 % and 1.7 % respectively. Protection of 3.5 % was reported among antiretroviral therapy (ART) naïve patients and 0 % protection among ART patients. Conclusions: Our findings showed prevalence of 2.7% HBsAb in the studied HIV positive patients with a protection of 3.5 % anti-HBs to HBV among antiretroviral therapy (ART) naïve patients in Ojo, Lagos. The low prevalence of HBsAb in HIV positive patients may be attributed to suppression of immune responses leading to the loss of previously developed protective antibody against HBV infection. We hereby suggest anti-HBs screening for all HIV positive patients and that those negative should be vaccinated to help them develop protective immunity to HBV infection.

Atypical and severe clinical presentations of seborrheic-like dermatitis (SLD) are associated with HIV infection, correlating with advanced disease or low CD4 counts. Previous studies documented histological findings characteristic of seborrheic dermatitis in HIV-positive patients. To expand current knowledge of the clinicopathological characteristics of SLD in South African HIV-seropositive individuals. This prospective study included HIV-seropositive adult patients presenting with SLD to a dermatology clinic from March 2017 to April 2018. A dermatologist established the diagnosis of SLD and the severity of the disease. Detail about antiretroviral therapy (ART), the latest CD4 count, and the viral load was retrieved from the patients' clinical records. Histopathological assessment of the patients' skin biopsies was recorded using standardized data sheets and semiquantifiable grades. This study included 13 women and 17 men. Fifty percent of patients showed severe or very severe SLD. Six (20.0%) patients presented with erythroderma. Statistical analysis did not show a significant correlation between severity of disease and CD4 count, viral load, or ART, respectively. This study confirmed that the presence of confluent parakeratosis, necrotic keratinocytes, plasma cells, neutrophils with leukocytoclasia, and leukoexocytosis are histopathological clues to SLD occurring in HIV-seropositive patients. SLD in HIV patients may present with varying clinical severity, including erythroderma. The association between the prevalence and severity of SLD with CD4 count, viral load, and ART requires further studies with larger patient populations. The presence of specific histopathological features in a skin biopsy of SLD is a clue to the diagnosis of HIV.

BackgroundEnterobacteriaceae is one of the main families of gram-negative bacilli responsible for serious infections in humans. The severity of infection by these bacteria is a product of many factors, including virulence properties and antimicrobial resistance. This severity may be further intensified if there is an association between these factors and a depressed immune system, such as in HIV patients. This study aimed to determine the distribution of representative virulence genes among key Enterobacteriaceae isolates from HIV-1 and non-HIV gastroenteritis patients and the relationship between carrying these virulence genes and antimicrobial susceptibility, seropositive status, and severity of symptoms associated with Enterobacteriaceae infections in Dschang Regional Hospital Annex.MethodologyA total of 200 gastroenteritis patients (100 HIV-1 and 100 non-HIV patients) were selected and evaluated for symptoms associated with gastroenteritis. Stool samples were obtained and cultured, from which Escherichia coli, Klebsiella pneumoniae, and Salmonella spp. isolates were obtained. Antibiotic susceptibility tests were performed on the isolates by agar disc diffusion using commonly used antibiotics. These isolates were tested for the possession of virulence genes by polymerase chain reaction (PCR); eae for E. coli, entB for K. pneumoniae, and pipD for Salmonella spp. Correlation tests and risk assessments were performed between the presence of virulence genes, antibiotic resistance, and specific symptoms.ResultsThe isolates obtained from HIV-positive and HIV-negative patients were, respectively, 61 against 62 for E. coli, 10 against 21 for K. pneumoniae, and 11 against 15 for Salmonella spp.These organisms showed the highest resistance to amoxicillin and clavulanic acid, while the least resistance was observed against ofloxacin, gentamicin, and amikacin in both groups of patients. The virulence genes showed a generally higher occurrence in isolates from HIV-negative patients than HIV-positive patients, with the eae gene 5/61 (8.20%) against 12/62 (19.35%), the entB gene 4/10 (40.00%) against 14/21 (66.66%), and the pipD gene 5/11 (45.45%) against 7/15 (46.46%) in HIV-positive and negative patients, respectively. There was a significant correlation between eae gene carriage and resistance against imipenem (p = 0.047), gentamycin (p = 0.047), and doxycycline (p = 0.029); entB gene carriage and resistance toward levofloxacin (p = 0.017) in K. pneumoniae; and pipD gene carriage and resistance against levofloxacin (p = 0.039), imipenem (p = 0.041), and doxycycline (p = 0.042). The carriage of the virulence genes was seen to be a stronger risk only for the resistance of K. pneumoniae to ceftriaxone (odds ratio (OR) = 2.286) and gentamycin (OR = 3.000), and Salmonella spp. against imipenem (OR = 2.750) and doxycycline (OR = 2.118). The development of severe symptoms correlated significantly with virulence gene carriage in isolates, mainly in HIV-positive patients with eae (p = 0.017) and pipD (p = 0.025), with a strong risk association with the pipD gene (OR = 2.665).ConclusionsAntibiotic resistance was associated with virulence gene carriage, indicating that virulence and antibiotic resistance can associate their effects and contribute to poor outcomes in the treatment of bacterial diseases in HIV patients. The possession of virulence genes increased the severity of symptoms associated with gastroenteritis in HIV-positive patients.

Background: Oropharyngeal candidiasis (OPC) is a very common opportunistic infection among HIV-positive patients, particularly in resource-limited settings. Although antiretroviral therapy is widely accessible, OPC continues to pose a major clinical challenge, particularly in sub-Saharan Africa. This study sought to explore and determine the risk factors linked to OPC in HIV-positive patients in Southwestern Nigeria. Materials and Methods: A prospective observational study was carried out at the PEPFAR adult clinic of Olabisi Onabanjo University Teaching Hospital in Sagamu, Nigeria, between February 2021 and January 2022. The study enrolled 411 consenting HIV-positive adult patients. Data collection involved the use of questionnaires, clinical examinations and laboratory analyses. Oral swabs were cultured on Sabouraud dextrose agar, and Candida species were identified through colonial morphology, microscopic characteristics, chrome agar identification, and API 20C kit tests. The data were analysed using SPSS version 17, with a statistical significance threshold of P &lt; 0.05. Results: Out of the 411 participants, 324 (78.8%) were female, while 87 (21.2%) were male. The average age of the participants was 44.9 years, and the mean CD4 count was 477.1 cells/μL. Thirty (7.3%) participants had clinical features of OPC, while 82 (20.0%) had Candida species isolated from their oral cavity. Significant associations were found between Candida colonisation and low CD4 counts (&lt;200 cells/μL, χ² =69.0504, P &lt; 0.001), high viral load (&gt;1000 copies/mL, χ² =17.3395, P &lt; 0.001) and infrequent oral hygiene practices (χ² =6.22, P = 0.045). Smoking and alcohol consumption also showed significant associations with Candida colonisation (χ² =1.007 and 0.219, respectively). Conclusion: The study underscores the critical impact of immunosuppression, inadequate oral hygiene and lifestyle factors such as smoking and alcohol use on the development of OPC in HIV-positive patients. To reduce the burden of OPC and enhance HIV care outcomes, early diagnosis, better oral hygiene practices and targeted interventions addressing these risk factors–particularly smoking and alcohol consumption–are essential for this population.

Background: Tuberculosis of the spine is a serious manifestation of the disease that causes debilitating injury. In HIV positive patients the incidence of skeletal tuberculosis increases to 60%. The MRI has become the gold standard for diagnosis and preoperative planning in spinal TB. The objective of this study was to assess the impact of HIV status on MRI findings in spinal tuberculosis patients at a tertiary public hospital in Pune, India. Methods: This was retrospective study of spinal TB patients admitted to a tertiary public hospital in Pune, India. Fifty patients with histopathological confirmation of spinal tuberculosis, HIV status and available MRI scans from 2017-2020 were identified. HIV status was positive in 16 and negative in 34. Males were predominant (27:23). Site, extent of disease, type of lesion, abscess volume, kyphotic deformity and skip lesions were reported. Results: There is no statistical difference in age and sex of the patients. The average abscess size in HIV positive group is more (9.63 sq.cm) as compare to (2.29 sq. cm) non HIV group. Average numbers of vertebrae involved in both groups are almost same (2.4:2.26). Average kyphotic angle is significantly more in non HIV group as compare to HIV group (10.8:15.38). skip lesions were more common in HIV group (6 out of 10 as compare to 6 out of 20). There was a positive correlation between abscess size and CD4 count in HIV patients. Conclusion: HIV negative patients have greater tubercular destruction as measured by resultant kyphosis. There is no difference in the incidence of location, type of vertebral involvement and number of vertebrae involved. Skip lesions were more common in HIV positive patients in our study. HIV positive patients show greater epidural abscess volume and are showing correlation with CD4 count.

HIV Status Does Not Impact on Outcome in Patients with Hodgkin Lymphoma Treated with ABVD Chemotherapy in the HAART Era,
